The guide rail fixed body includes a guide rail 1, a rack 4, a wire trough 6, a copper bar 7 and a cover plate 8, and the moving slider assembly includes a moving slider 22, a nylon slider 14, a support bearing 2, a support shaft 3, an anti-backlash bearing 19, a swing arm 20, a rubber body 21, a moving gear box 5, a carbon brush 15, an insulator 16, a second spring 17, a single-end terminal 18, a first positioning tooth 9, a second positioning tooth 11, a guide rod 12, a first spring 13 and an unlocking wheel 10. Among them, a groove is formed on both sides of the bottom of the guide rail 1 along its length direction, and a rack 4 is installed in the groove. The rack 4 is used to provide power support for the moving slider assembly. The rack 4 can match the gear on the moving gear box 5. The moving gear box 5 is fixedly connected in the middle of the moving slider 22. The moving gear box 5 is driven by a motor. The rack 4 and the moving gear box 5 form a moving pair to provide moving power for the moving slider assembly. A wire groove 6 is installed on the side of the guide rail 1. The wire groove 6 has efficient insulation performance. A copper bar 7 is arranged in the wire groove 6. The copper bar 7 can be connected to the vehicle power supply through a connecting wire. The copper bar 7 is used to connect the vehicle power supply to provide power for the moving slider assembly and equipment. In addition, two cover plates 8 are installed on the outer side of the upper part of the guide rail 1. The cover plate 8 can block the gap between the guide rail 1 and the moving slider 22 to prevent dust and other foreign matter from falling into the guide rail 1 (see Figure 2 and Figure 3 ).

[0025] A support bearing 2 is provided in the guide rail 1. The support bearing 2 is sleeved on the support shaft 3. The support bearing 2 is connected to the moving slider 22 through the support shaft 3. In this way, a support bearing 2 is provided at both ends of the moving slider 22. The support bearing 2 matches the support shaft 3 so that the support bearing 2 supports the moving slider 22 in the guide rail 1 through the support shaft 3. A rubber body 21 is provided on the bottom support plate of the moving slider. The rubber body 21 can contact the swing end of the swing arm 20. The support bearing 2 is connected to the anti-backlash bearing 19 through the swing arm 20. One end of the swing arm 20 is fixed on the support shaft 3 of the support bearing 2, and the other end is fixed on the shaft of the anti-backlash bearing 19 (see Figure 6), the rubber body 21 presses the anti-backlash bearing 19 fixed on the swing arm 20 onto the guide rail 1. In this way, the anti-backlash bearing 19 is connected to the swing arm 20 through the moving support bearing 2, and the swing end of the swing arm 20 is firmly pressed on the rubber body 21 fixed on the bottom support plate of the moving slider 22, and then the anti-backlash bearing 19 is pressed firmly on the upper part of the groove of the guide rail 1, thereby playing a role in eliminating the gap between the moving slider 22 and the vertical surface of the guide rail 1. Nylon sliders 14 are respectively installed at the four corners of the bottom of the moving slider 22 to eliminate the gap between the moving slider 22 and the guide rail 1 in the horizontal direction.

[0026] The movable slider 22 is provided with two parallel guide rods 12, and the first springs 13 are respectively installed on the two guide rods 12. The first positioning tooth 9 and the second positioning tooth 11 are sleeved on the guide rods 12 and can flexibly move up and down along the guide rods 12. The first positioning tooth 9 and the second positioning tooth 11 are connected by screws and merged into a positioning tooth assembly. The first positioning tooth 9 and the second positioning tooth 11 are respectively provided with half holes, and the two half holes form a hole for sleeved on the guide rod 9. The lower ends of the first positioning tooth 9 and the second positioning tooth 11 can conflict with the first spring 13, and the first positioning tooth 9 or the second positioning tooth 11 is pushed up by the first spring 13. An eccentric unlocking wheel 10 that can rotate flexibly is provided above the first positioning tooth 9 and the second positioning tooth 11 on the movable slider 22. When the moving slider assembly is in a locked state, the first positioning tooth 9 and the second positioning tooth 11 are lifted up and contacted with the eccentric unlocking wheel 10 under the restoring force of the first spring 13 to clamp the eccentric unlocking wheel 10 and lock the position of the moving slider assembly on the guide rail 1; when the moving slider assembly needs to move, the first positioning tooth 9 and the second positioning tooth 11 are pressed down to leave the eccentric unlocking wheel 10, thereby unlocking the position locking function of the moving slider assembly on the guide rail 1 (see Figure 4 ). The function of the eccentric unlocking 10 is to solve the problem of the movable slider assembly being fixed on the guide rail 1; the movable slider assembly is in an unlocked state when it is moving, and when it is not moving, the movable slider assembly is locked on the guide rail 1 and the position is fixed.

[0027] In addition, an insulator 16 is installed at one end of the moving slider 22, and a carbon brush 15 and a second spring 17 are installed in the insulator 16. The second spring 17 is sleeved on the carbon brush 15. One end of the carbon brush 15 contacts the copper bar 7 on the guide rail fixed body, and the other end is connected to the single-end terminal 18. In this way, the second spring 17 presses the carbon brush 15 against the copper bar 7 to connect the power supply. The single-end terminal 18 is installed on the end surface of the moving slider 22 to provide power for all electrical equipment on the moving slider assembly.
