In order to realize the splicing and installation of any pair of first decorative plates and second decorative plates spliced together. As shown in fig. 1, the decoration board assembly 1 further includes a hanging structure 14 corresponding to any pair of the first decoration board and the second decoration board which are spliced together, and the hanging structure 14 is used for splicing the first decoration board and the second decoration board together and fixing the first decoration board and the second decoration board on the wall surface 2.

Specifically, the hanging structure 14 corresponding to the first spliced decorative plate 11 and the second spliced decorative plate 12 which are spliced together is a first hanging structure, and the hanging structure 14 corresponding to the second spliced decorative plate 12 and the third spliced decorative plate 13 which are spliced together is a second hanging structure.

The structure of the mounting structure 14 will be explained below. As shown in fig. 2, in some embodiments, the hanging structure 14 includes a mounting keel 141 and a clip member 142. Wherein the mounting keel 141 includes a first connection plate 1411 and a mounting plate 1412. The first connecting plate 1411 is used for being fixedly connected with the wall surface 2. The mounting plate 1412 is perpendicular to the first connection plate 1411, and the mounting plate 1412 is connected with the first connection plate 1411 as an integral structure.

The mounting keel 141 is elongated as a whole, and the length of the mounting keel 141 extends in the vertical direction (i.e., the Y direction in fig. 2). The mounting keel 141 has an L-shaped cross-section taken by a plane perpendicular to the length direction thereof. The mounting plate 1412 is used for fixedly connecting with the first decorative plate. The first connecting plate 1411 is provided with a locking hole 14111 penetrating the first connecting plate 1411. The clamping and hanging piece 142 is hung on the hole wall of the clamping hole 14111 of the first connecting plate 1411 and is used for being fixedly connected with the second decorative plate so as to splice the first decorative plate and the second decorative plate. Two clamping pieces 142 are correspondingly configured on one installation keel 141, and the two clamping pieces 142 are arranged at intervals along the length direction of the installation keel 141.

After the first connecting plate 1411 is fixedly connected to the wall surface 2, the first connecting plate 1411 is perpendicular to the wall surface 2, and the mounting plate 1412 is parallel to the wall surface 2. Wherein the wall surface 2 extends in the X-direction and the Y-direction. At this time, the insertion direction of the click hole 14111 is the X direction.

The above description is given by way of example in which two engaging members 142 are disposed on one mounting keel 141. The present application is not limited to the configuration of several fasteners 142 on one mounting keel 141. In other embodiments, one, three, four or more clamping hanging members 142 may be disposed on one mounting keel 141, and all of them may be used as long as the stability of the first decorative plate and the second decorative plate after mounting is ensured to meet the requirement.

The mounting keel 141 has an L-shaped cross section taken along a plane perpendicular to the longitudinal direction thereof. However, the shape of the cross section of the mounting keel 141 taken perpendicular to the longitudinal direction thereof is not limited in the present application. In other embodiments, the mounting keel 141 may also be T-shaped in cross-section taken perpendicular to its lengthwise plane, as shown in figure 3. Specifically, the first connecting plate 1411 is connected to a middle region of the mounting plate 1412, and the same may be used. In a word, after the first connecting plate 1411 is fixedly connected with the wall surface 2, the mounting plate 1412 is far away from the wall surface 2, so that the first decorative plate is conveniently and fixedly connected.

In addition, as for the materials of the installation keel 141 and the clamping and hanging piece 142, the application is not limited, and metal materials, plastics or wood-plastic materials can be selected and used.

Based on this, when the decorative panel assembly 1 is installed, the installation keel 141 is first fixedly installed on the back surface of the first decorative panel facing the wall surface 2 (the surface facing the wall surface 2 is defined as the back surface, the surface facing away from the wall surface 2 is defined as the front surface, and the rest surfaces are defined as the side surfaces), and the clip member 142 is fixedly installed on the back surface of the second decorative panel facing the wall surface 2. Then be close to wall 2 with first decorative board and be fixed in on wall 2 with the installation fossil fragments 141 that correspond to realize that first decorative board installs on wall 2. Next, the second decorative plate is close to the wall surface 2, and the clip 142 is hung on the hole wall of the clip hole 14111 of the first connecting plate 1411 of the mounting keel 141, so that the second decorative plate is mounted on the wall surface 2, and the first decorative plate and the second decorative plate are spliced.

The decorative plate assembly 1 is installed in the above mode, and installation of the decorative plate can be completed without arranging a groove on the side face of the decorative plate. The processing difficulty of the decorative plate is reduced, and the decorative plate is made of a material with higher strength without needing to select the material with higher strength for ensuring the strength of the groove wall of the groove, so that the manufacturing cost of the decorative plate can be reduced.

It should be noted that, when the decoration plate assembly 1 can be understood as including a plurality of pairs of first decoration plates and second decoration plates, corresponding installation keels 141 may be installed on all the first decoration plates, corresponding clamping and hanging members 142 may be installed on all the second decoration plates, and then the first decoration plates and the second decoration plates are installed close to the wall surface 2, which may also be used.

It should be noted that, for the decorative plates (such as the first splicing decorative plate 11 and the third splicing decorative plate 13 in fig. 1) located at the edges in the decorative plate assembly 1, except that the fixed connection with the wall surface 2 is realized at one end of the decorative plate close to the middle (such as the second splicing decorative plate 12 in fig. 1) through the hanging structure 14, the fixing with the wall surface 2 can also be realized at one end of the decorative plate far from the middle in other ways, and the realization ways are more, and are not the technical solutions that need protection in this application, and are not described herein again.

It should be noted that the trim panel assembly 1 shown in fig. 1 includes three trim panels, namely, a first trim panel 11, a second trim panel 12, and a third trim panel 13. However, the number of the decorative boards in the decorative board assembly 1 is not limited in the present application, and in other embodiments, the decorative board assembly 1 may further include more than three decorative boards, in which case, any three decorative boards spliced together in sequence may form the first spliced decorative board 11, the second spliced decorative board 12, and the third spliced decorative board 13 spliced in sequence.

Then: it is understood that the first decorative plate 01 forms a first spliced decorative plate 11, the second decorative plate 02 forms a second spliced decorative plate 12, and the third decorative plate 03 forms a third spliced decorative plate 13. Meanwhile, it can be understood that the second decorative plate 02 forms a first spliced decorative plate 11, the third decorative plate 03 forms a second spliced decorative plate 12, and the fourth decorative plate 04 forms a third spliced decorative plate 13. Meanwhile, it can be understood that the third decorative plate 03 forms a first spliced decorative plate 11, the fourth decorative plate 04 forms a second spliced decorative plate 12, and the fifth decorative plate 05 forms a third spliced decorative plate 13. In the case where the trim panel assembly 1 includes more trim panels, it is also understood in accordance with the above-described rules.

The structure of the catching piece 142 will be explained. As shown in fig. 5, in some embodiments, the clip member 142 includes a second web 1421 and a clip web 1422. The second connecting plate 1421 is used to be fixedly connected to a second decorative panel. The engaging plate 1422 is hung on the hole wall of the engaging hole 14111 of the first connecting plate 1411. The clamping plate 1422 and the second connecting plate 1421 are connected as an integral structure.

Next, how the engaging plate 1422 is hooked on the hole wall of the engaging hole 14111 of the first connecting plate 1411 will be described. As shown in fig. 5, in some embodiments, clamp plate 1422 includes a transition plate 14221 and a clamp 14222. One end of the transition plate 14221 is connected to the second connecting plate 1421, and the other end is connected to the chuck 14222 to form an integral structure. A slot 14223 is formed between the clamp 14222 and the transition plate 14221. The clamp 14222 is a plate-shaped structure, and is perpendicular to the transition plate 14221, and the clamp 14222 is parallel to the second connecting plate 1421. As shown in fig. 6, the hole wall of the locking hole 14111 of the first connecting plate 1411 is locked in the locking groove 14223, and the transition plate 14221 is attached to the first connecting plate 1411. In addition, when the hooking member 142 is hooked on the mounting keel 141, the head 14222 is perpendicular to the first connection plate 1411.

Based on this, when splicing first decorative board and second decorative board, stretch into the dop 14222 of card pendant 142 in the card hole 14111 of installation fossil fragments 141, then move the second decorative board down for the pore wall card of card hole 14111 is in draw-in groove 14223, thereby realizes card pendant 142 and hangs on installation fossil fragments 141, and then realizes the concatenation of first decorative board and second decorative board, and is very simple and convenient.

Note that the wall of the locking hole 14111 is the structure of the first connection plate 1411 around the locking hole 14111.

In order to improve the stability of the clamping hanging piece 142 after being hung on the installation keel 141. As shown in fig. 7, the card slot 14223 includes a rectangular slot 142231 and a trapezoidal slot 142232 arranged in the Y direction. The open, constricted end of trapezoidal slot 142232 communicates with and smoothly transitions into rectangular slot 142231. The surface of the rectangular groove 142231 away from the trapezoidal groove 142232 serves as the groove bottom of the clamping groove 14223; two side surfaces of the hole wall of the locking hole 14111 are attached to the corresponding wall surface of the rectangular groove 142231.

The rectangular groove 142231 has a rectangular cross section taken perpendicular to the surface of the chuck 14222, the trapezoidal groove 142232 has a trapezoidal cross section taken perpendicular to the surface of the chuck 14222, and an end of the trapezoidal groove 142232 corresponding to the upper bottom of the trapezoid forms an open constricted end.

Based on this, as shown in fig. 6, after the hanging member 142 is hung on the mounting keel 141, the hole wall of the clamping hole 14111 can extend into the rectangular groove 142231, and two opposite side surfaces of the hole wall of the clamping hole 14111 in the X direction are respectively attached to opposite groove wall surfaces of the rectangular groove 142231 in the X direction, so that the hanging member 142 is limited by the hole wall of the clamping hole 14111 in the X direction, and the hanging member 142 cannot move relative to the mounting keel 141 in the X direction, so that the stability of the hanging structure 14 is high.

In addition, because the clamping groove 14223 is provided with the trapezoidal groove 142232, in the process of hanging the clamping piece 142 on the installation keel 141, the hole wall of the clamping hole 14111 can easily extend into the clamping groove 14223, so that the hanging of the clamping piece 142 on the installation keel 141 is convenient, and the hanging efficiency of the decorative plate assembly 1 can be improved.

It should be noted that, in order to ensure that the clip member 142 can be smoothly hung on the mounting keel 141, the size of the clip hole 14111 in the Y direction should be larger than that of the clip 14222 in the Y direction.

To facilitate insertion of the cartridge 14222 into the snap hole 14111. As shown in fig. 8, the card holes 14111 include rectangular holes 141111 and trapezoidal holes 141112 arranged in the Y direction. The flared end of trapezoidal shaped aperture 141112 communicates with and smoothly transitions into rectangular shaped aperture 141111.

When the hooking member 142 is hung on the mounting keel 141, the bottom of the slot 14223 of the hooking member 142 faces the contraction end of the trapezoidal hole 141112. Also, the chuck 14222 is engaged in the trapezoidal hole 141112.

It should be noted that the rectangular hole 141111 has a rectangular cross section taken perpendicular to the surface of the first connection plate 1411. The trapezoidal hole 141112 has a trapezoidal cross section taken perpendicular to the surface of the first connection plate 1411. One end of the trapezoidal hole 141112 corresponding to the lower bottom of the trapezoid forms an expanded end, and one end of the trapezoidal hole 141112 corresponding to the upper bottom of the trapezoid forms a contracted end.

Therefore, in the process of hanging the clip member 142 on the mounting keel 141, since the size of the rectangular hole 141111 in the Z direction is large, the clip 14222 of the clip member 142 can easily extend into the clip hole 14111, and then can be hung in the trapezoidal hole 141112 after moving down. The hanging of the clamping hanging piece 142 on the installation keel 141 is convenient, and the hanging efficiency of the decorative plate assembly 1 can be improved. Wherein the Z direction is perpendicular to both the X direction and the Y direction.

In order to improve the stability of the hanging structure 14. As shown in fig. 8, the constricted end of the trapezoidal aperture 141112 has an aperture width equal to the thickness of the collet 14222. The width of the constricted end of the trapezoidal aperture 141112 is oriented perpendicular to the mounting plate 1412 (i.e., extends in the Z-direction in fig. 8), and the thickness of the tap 14222 is also oriented perpendicular to the mounting plate 1412.

In this way, after the hanging member 142 is hung on the mounting keel 141, the groove bottom of the catching groove 14223 can be attached to the wall surface of the trapezoidal hole 141112 away from the rectangular hole 141111. In addition, the chuck 14222 is limited by the hole wall of the trapezoidal hole 141112 in the Z direction, and the engaging member 142 cannot move relative to the mounting keel 141 in the Z direction, so that the stability of the hanging structure 14 is high.
