Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, if not conflicting, the embodiments of the present invention and the features of the embodiments may be combined with each other within the scope of protection of the present invention.

Referring to fig. 1 to 3, the present invention provides a position self-checking computer, including a computer motherboard, where the computer motherboard includes a printed circuit board 100, a position detector 200 and a central processing unit (not shown in the figure), and it can be understood that the computer motherboard further includes elements such as a BIOS chip, an I/O control chip, a panel control switch interface, an indicator light plug-in, an expansion slot, and the like, and except for the position detector 200, the other components are the prior art, and therefore, the structure thereof is not described herein again.

The position detector 200 includes a fluid storage member 21, a conductive fluid 22, a signal pin 23, an isolation sleeve 24, a fixing plate 25, and a signal conversion member 26, wherein a storage groove 211 for storing the conductive fluid 22 is provided in the fluid storage member 21, an inert gas is stored in the storage groove 211, and the sum of the volume of the conductive fluid 22 and the volume of the inert gas is equal to the volume of the storage groove 211. It is understood that the inert gas may be helium or neon, etc. The signal pin can be protected by the inert gas. The signal pin 23 may be a copper pin, a silver pin, or other materials with good conductivity.

Both the fluid housing member 21 and the housing groove 211 may be a polyhedron or a rotator, and in this embodiment, the fluid housing member 21 is a hollow cylindrical structure with one end open and the other end closed; the receiving groove 211 is cylindrical, and a notch of the receiving groove 211 is located at an upper end surface of the fluid receiving member 21. It is understood that the fluid housing member 21 is made of an insulating material or an inner wall surface thereof is plated with an insulating layer.

The conductive fluid 22 is located in the accommodating groove 211, the volume of the conductive fluid 22 is smaller than the volume of the accommodating groove 211, and the distance between the liquid level of the conductive fluid 22 and the notch of the accommodating groove 211 is preset, wherein the type of the conductive fluid 22 and the preset distance can be selected according to the requirement, and are not specifically limited herein. The resistivity of the conductive fluid 22 is much less than the resistivity of the resistance wire, and the resistivity of the conductive fluid 22 is negligible compared to the resistivity of the resistance wire. Therefore, the resistance value between the signal pins 23 is measured from the signal collector as the sum of the resistance values of the portions of the signal pins 23 above the liquid level of the conductive fluid 22 to be measured, and thus the measurement accuracy is high. In this embodiment, the conductive fluid 22 is a sodium chloride solution.

The number of the signal pins 23 is a plurality, and the signal pins 23 are arranged in the accommodating groove 211 at equal intervals and extend along the longitudinal direction of the accommodating groove 211. Each of the signal pins 23 is in contact with the conductive fluid 22 when the fluid housing member is placed vertically. In the present embodiment, in order to simplify the operation and improve the measurement accuracy, the number of the signal pins 23 is an even number, all the signal pins 23 have the same diameter, and the adjacent signal pins 23 are arranged at equal intervals. Specifically, the total number of the signal pins 23 is 6, and a connecting line between adjacent signal pins 23 forms an angle of 120 ° with an adjacent connecting line. It is understood that the number and diameter of the signal pins 23 can be set according to the requirement, and the number and diameter are not limited in detail.

The isolation sleeve 44 covers the signal pin 23, a gap 27 is formed between the isolation sleeve 44 and the signal pin 23, and the gap 27 is used for allowing the conductive fluid 22 to flow to the surface of the signal pin 23. Through setting up spacer sleeve 44, therefore the influence of rocking of liquid level in fluid storage component 21 to liquid level in spacer sleeve 44 is very little, can show like this and reduce to rock the interference to the measuring result, has improved measurement accuracy. The cross section of the gap 27 can be crescent or annular, and the like, in order to improve the measurement accuracy and provide the convenience of use, the isolation sleeve 44 and the signal needle 23 are coaxially arranged, and the cross section of the gap 27 is annular, so that the hard disk can be monitored no matter which direction the hard disk inclines in the use process. It is understood that a holding member may be disposed in the gap 27 and held between the isolation sleeve 44 and the signal pin 23.

To fit in a variety of complex environments, the upper end of the isolation sleeve 44 is positioned above the conductive fluid 22, and the lower end of the isolation sleeve 44 is inserted within the conductive fluid 22. The lower end surface of the spacer 44 is spaced apart from the bottom wall of the receiving groove 211 by a predetermined height, thereby facilitating the conductive fluid 22 to flow into the gap 27. In order to improve the structural stability and ensure the measurement accuracy, in another embodiment, the lower end of the isolation sleeve 44 is inserted into the conductive fluid 22 and abuts against the bottom wall of the accommodating groove 211, and a liquid inlet gap is provided at the lower end surface of the isolation sleeve 44, and the liquid inlet gap is communicated with the gap 27 and the accommodating groove 211.

By providing the fixing plate 25, leakage of the conductive fluid 22 can be avoided during use. The upper end of the spacer 44 is inserted into the through hole and connected to the fixing plate 25, so that the spacer 44 can be more securely mounted.

The signal conversion component 26 is connected to the signal pin 23 and the central processing unit, and is configured to convert an analog signal output by the signal pin 23 into a digital signal. The signal conversion part 26 includes a circuit board 261 and an analog-to-digital conversion circuit (not shown), and the circuit board 261 is covered on the fixing plate 25 and connected to the fixing plate 25, so that the present invention has a compact structure and is convenient for users to use. The analog-to-digital conversion circuit is disposed on the circuit board 261 and electrically connected to the signal pin 23, and is configured to convert an analog signal transmitted by the signal pin 23 into a digital signal. In practical application, when the host computer inclines, the central processing unit calculates the inclination according to the digital signal, and when the inclination is greater than a preset value, the central processing unit controls a display of the computer to send out a reminding signal. It is understood that the analog-to-digital conversion circuit has a high input impedance characteristic.

The working principle of the invention is as follows: taking the number of the signal pins 23 as 6 as an example, when the fluid containing member 21 is not inclined, the six signal pins 23 are located at the same height above the liquid surface of the conductive fluid 22, and therefore the resistance value difference between every two signal pins 23 is zero. After the liquid level is inclined, the height of the signal needle 23 above the liquid level changes, the resistance value of the signal needle also changes, and the height difference of the part of the signal needle 23 above the liquid level can be calculated according to the linear relation that the resistance value and the length of the uniform resistance wire are in direct proportion. It is possible to determine a unique liquid surface position and calculate the angle of the liquid surface with respect to the bottom of the fluid containing member 21, i.e. the inclination of the fluid containing member 21. Thus, the tilt angle of the present invention is calculated. Because the relative variation between the resistors is adopted to measure and calculate the inclination angle, the obtained result is hardly influenced by the external environment, namely the absolute variation of the resistors is influenced by the external environment, and the relative variation is hardly influenced by the external environment.

It can be understood that, in another embodiment, the computer further includes four servo motors and four lead screws in one-to-one transmission connection with the servo motors, the four servo motors are correspondingly disposed at four corners of the bottom of the main body of the computer, and the central processing unit controls the rotation shaft of the servo motor to rotate by a preset angle according to the inclination of the fluid receiving member 21, so as to control the height of the lead screw extending out of the bottom of the main body of the computer, so that the computer is kept not to be inclined, and the computer is better protected.

In summary, in the present invention, through the cooperation among the fluid containing member 21, the conductive fluid 22, the signal pins 23 and the signal converting member 26, the containing groove 211 is disposed in the fluid containing member 21, the conductive fluid 22 is located in the containing groove 211, the volume of the conductive fluid 22 is smaller than the volume of the containing groove 211, the number of the signal pins 23 is several, the signal pins 23 are disposed at equal intervals and extend along the longitudinal direction of the containing groove 211, and each signal pin 23 is in contact with the conductive fluid 22. Therefore, when the computer host inclines, the fluid containing part 21 inclines, when the fluid containing part 21 inclines, the signal output by the signal needle 23 changes, the inclination is calculated according to the change amount of the signal, and the user is reminded whether the hard disk is horizontally placed or not according to the inclination.
