[0027] The automatic lifting table device of this utility model will be further described below with reference to specific embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of this utility model.

[0028] Example 1

[0029] Figure 1-9 The automatic lifting table device of this embodiment is shown, including a housing assembly, a table 22, a motor assembly 28, and a belt drive assembly. The belt drive assembly is driven by the motor assembly 28 and is disposed within the housing assembly. The belt drive assembly is composed of a left front component assembly 11a, a right front component assembly, and a rear component assembly 13A. The housing assembly is assembled from a top plate 1, a bottom plate 6, a front plate 2, a rear plate 7, a left plate 3, and a right plate 4. A guide rail slider 9 is provided on the bottom plate 6, and the guide rail slider 9 slides in engagement with a guide rail 25 on the back of the table 22. The two ends of the support rod 26 are fixed between the front plate 2 and the rear plate 7 by a support rod front plate 10 and a support rod rear plate 12. The motor assembly 28 is mounted on the top plate 1 via a motor bracket 30 using two mounting bolts 36. A notch 2a is provided between the front plate 2 and the bottom plate 6, and a limiting plate 5 is provided at the notch 2a. After the belt 21 drives the tabletop 22 to slide completely through the notch 2a, the limiting plate 5 restricts the tabletop 22 from continuing to move downwards. A decorative panel 23 is provided on the tabletop 22. Figure 4As shown, a sliding bearing 16 is provided on the bearing support plate 35. The bearing support plate 35 is fixed to the support rod seat 34 by two mounting bolts 36. The support rod seat 34 can move back and forth on the support rod 26 through the sliding bearing 16. A limiting seat 24 is provided on the base plate 6 to determine the initial position of the tabletop 22. The support rod seat 34 and the belt 21 are limited by a positioning plate 33. The support rod seat 34 is rotatably connected to the tabletop 22. A spring 31 is provided between the support rod seat 34 and the tabletop 22. Its function is to provide a reverse force to the tabletop 22 when the tabletop 22 is in the open state, which can better improve the stability of the tabletop 22 when it is in the open state. Under the action of the spring, the tabletop will not wobble due to external factors such as road bumps when it is in the open state. A threaded ring 32 is also provided between the support rod seat 34 and the tabletop 22 to limit their axial relative position.

[0030] like Figure 2 As shown, the left front component assembly 11a includes two front belt supports 11 with front bearings 14, a front pulley shaft 18, and a front pulley 17. The front pulley 17 is mounted on the front pulley shaft 18, which is installed between the front bearings 14 of the two front belt supports 11. The right front component assembly (not shown) has the same structure as the left front component assembly 11a. The left front component assembly 11a and the right front component assembly are mounted to the front panel 2 and the top panel 1 by mounting bolts 36. Figure 3 As shown, the rear component assembly 13A is formed by connecting the left rear component assembly 13a and the right rear component assembly 13b via a motor shaft 27, which is driven by a motor assembly 28. The left rear component assembly 13a includes two rear belt supports 13 with rear bearings 15 mounted on them, a rear pulley shaft 20, and a rear pulley 19. The rear pulley shaft 20 is mounted between the rear bearings 15 of the two rear belt supports 13, and the rear pulley 19 is mounted on the rear pulley shaft 20. The left rear component assembly 13a and the right rear component assembly 13b have the same structure and are symmetrically arranged. The rear component assembly 13A is pre-installed on the rear plate 7, the top plate 1, and the bottom plate 6 by mounting bolts 36. Figure 6 As shown, the front pulley 17 and the rear pulley 19 are respectively provided with front gear teeth 17a and rear gear teeth 19a, and the front gear teeth 17a and the rear gear teeth 19a mesh and rotate with the belt teeth 21a of the belt 21. Figure 5 As shown, the tension of the belt 21 can be adjusted by adjusting the pre-mounting point of the rear component assembly 13A on the rear plate 7. (Combined with...) Figure 5 and Figure 7As shown, after the wiring harness connector 29, serving as the power and signal output terminal 29a, connects to the signal input terminal 28a on the motor assembly 28, when the motor assembly 28 receives the drive signal, it drives the support rod seat 34 to move from the positioning start point to the positioning end point on the support rod 26 via the belt 21. Simultaneously, it drives the tabletop 22 to slide on the guide rail slider 9 via the guide rail 25. When the tabletop 22 is fully opened, the motor assembly 28 stalls and stops driving. The closing process of the tabletop 22 is the reverse of the opening process.
