[0001] This application relates to the field of lifting mechanism technology, specifically a lifting mechanism drive module. Background Technology

[0002] A lifting mechanism is a mechanical device used to achieve vertical movement of objects, and it is widely used in various fields. Its basic function is to raise or lower objects vertically. Depending on the design and application, the types and principles of lifting mechanisms also differ.

[0003] In the use of bedside tables, in order to allow users to easily adjust the height of the desktop according to their personal needs, a lifting mechanism is usually installed at the bottom of the desktop, which makes it easier to adjust the height of the desktop.

[0004] However, if the lifting system malfunctions during use, the table may slip or fall rapidly. A rapidly falling table may hit the user or objects below, and if there are fragile items on the table, these items may fall or be damaged. Therefore, it is necessary to provide a lifting mechanism drive module to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a lifting mechanism drive module that prevents the tabletop from slipping or falling rapidly, thus preventing it from colliding with the user or objects below and preventing items on the table from falling off.

[0013] Furthermore, the outer side of the card plate is provided with an upward inclined surface, and the card slot is composed of a downward inclined surface and a horizontally arranged horizontal plate, with the card plate located on the horizontal plate of the card slot.

[0014] Furthermore, a magnet ring is fixedly installed on the output shaft of the drive cylinder. The magnet ring is located below the arc ring, and the magnet ring rises and falls together with the arc ring. The magnet ring is an electromagnet.

[0015] Furthermore, a base is fixedly installed at the lower end of the lifting mechanism, and a roller is fixedly installed at the lower end of the base.

[0016] The beneficial effects of this application are: the lifting mechanism drive module provided by this application is equipped with a braking mechanism to support the output shaft of the drive cylinder.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figures 1-2 As shown, this application provides a lifting mechanism drive module for adjusting the height of a bedside table. The bedside table includes a tabletop 1, which has a teacup plate 11. An office board 12 is provided on one side of the teacup plate 11. A connecting rod 4 is fixedly installed on the lower end of the office board 12 and the teacup plate 11, and the office board 12 and the teacup plate 11 are connected by the connecting rod 4.

[0034] Meanwhile, a lifting mechanism 2 is fixedly installed at the lower end of the teacup plate 11, and a base 6 is fixedly installed at the lower end of the lifting mechanism 2. The lifting mechanism 2 is supported by the base 6, and a roller 7 is fixedly installed at the lower end of the base 6, which facilitates the adjustment of the overall position of the bedside table.

[0035] Furthermore, a protective shell 8 is provided on the outside of the lifting mechanism 2. The protective shell 8 is used to protect the lifting mechanism 2 and prevent dust and other impurities from entering the interior of the lifting mechanism 2.

[0036] like Figures 3-4 As shown, the lifting mechanism 2 has a drive cylinder 21 fixedly installed on the upper end of the base 6. The drive cylinder 21 is located inside the protective shell 8, and a support rod 22 is fixedly installed on the lower end of the teacup plate 11. The support rod 22 is located on the upper end of the drive cylinder 21. The support rod 22 is coaxially arranged with the output shaft of the drive cylinder 21. In this application, a fixing pipe clamp 23 is fixedly installed between the output shaft of the drive cylinder 21 and the support rod 22, and the drive cylinder 21 and the support rod 22 are fixed by the fixing pipe clamp 23.

[0037] To prevent the table from falling rapidly, such as Figures 4-6 As shown, a braking mechanism 3 is provided between the driving cylinder 21 and the protective shell 8. The braking mechanism 3 has an arc ring 31 fixedly installed on the outside of the fixed pipe clamp 23. Fixed posts 32 are fixedly installed at both ends of the arc ring 31. A limiting shell 33 is fixedly installed at the outer end of the fixed post 32. The lower end of the limiting shell 33 protrudes from the fixed post 32. A connecting plate 34 is rotatably connected inside the limiting shell 33. A clamping plate 35 is fixedly installed on the side of the connecting plate 34 away from the limiting shell 33 facing the protective shell 8. An upward inclined surface is provided on the outer side of the clamping plate 35.

[0038] Meanwhile, the inner wall of the protective shell 8 is provided with multiple sets of slots 81. Each slot 81 is composed of a downward-facing inclined surface and a horizontally arranged transverse plate. Therefore, the slot 81 and the plate 35 cooperate with each other. It should be noted that when the plate 35 is engaged with the slot 81, the plate 35 is located on the transverse plate of the slot 81, which will hold the plate 35 in place and prevent it from descending.

[0039] Meanwhile, a compression spring 36 is fixedly installed between the connecting plate 34 and the limiting shell 33. The compression spring 36 can prevent the connecting plate 34 from shaking randomly and pull the card plate 35 into the card slot 81 in the normal state.

[0040] It should be noted that the drive cylinder 21 is equipped with a remote control for switching on and off, which the user can use to control the switch on and off of the drive cylinder 21.

[0041] In summary: When it is necessary to adjust the height of the tabletop 1, the drive cylinder 21 drives the output shaft upward, which in turn drives the arc ring 31 and the support rod 22 upward, pushing the tabletop 1 upward.

[0042] At the same time, the connecting plate 34 and the clamping plate 35 will move upwards simultaneously, causing the inclined surface of the clamping plate 35 to slide upwards along the inclined plate of the clamping slot 81. This will also cause the connecting plate 34 to rotate outwards and stretch the compression spring 36 outwards until the clamping plate 35 is engaged in the next clamping slot 81. The above actions are repeated until the drive cylinder 21 stops. At this time, the clamping plate 35 is still engaged in the clamping slot 81, thus supporting the output shaft of the drive cylinder 21. Therefore, if the lifting system malfunctions during use, the tabletop 1 will not slip backwards or fall rapidly, preventing it from hitting the user or objects below and preventing items on the table from falling off.

[0043] In this application, a magnet ring 5 is fixedly installed on the output shaft of the drive cylinder 21. The magnet ring 5 is located below the arc ring 31 and moves up and down together with the arc ring 31. It should be noted that the magnet ring 5 is an electromagnet, and its control switch is electrically connected to the switch remote control, and is opposite to the control switch of the drive cylinder 21. It can be understood that when the drive cylinder 21 is extended upward by the switch remote control, the magnet ring 5 is in the closed state. When the drive cylinder 21 is retracted upward by the switch remote control, the magnet ring 5 is in the open state. Therefore, it will pull the connecting plate 34 outward, so that the locking plate 35 is disengaged from the locking slot 81, which facilitates the lowering of the table 1.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
