The user can adjust to the most suitable position according to his own height, reduce fatigue and discomfort that may occur during long-term use, and improve the comfort during use.

[0052] It can be understood that, with reference to Figures 1 to 3In the embodiment of the utility model, the scissor arm mechanism 300 includes at least one group of scissor arm assemblies 310, the scissor arm assembly 310 includes the first scissor arm 311 and the second scissor arm 312 of middle pivot connection, and the opposite two ends on the first scissor arm 311 and the second scissor arm 312 are rotatably provided with the sliding component 320;The sliding component 320 of the upper end of the first scissor arm 311 and the second scissor arm 312 is slidably connected with the second frame body 200, and the sliding component 320 of the lower end of the first scissor arm 311 and the second scissor arm 312 is slidably connected with the first frame body 100,

[0053] Among them, the first drive mechanism 400 is transmission connection with the first scissor arm 311, and the second drive mechanism 500 is transmission connection with the second scissor arm 312.

[0054] Adopt the above structure, through the first drive mechanism 400, user can adjust the height of the second frame body 200 according to own height demand, make the equipment can adapt to the body size of different users.The design of scissor arm assembly 310, especially the first scissor arm 311 and the second scissor arm 312 of middle pivot connection, can provide stable support structure.When the sliding component 320 is connected with the first frame body 100 and the second frame body 200, the stability of the whole mechanism when adjusting height can be ensured.The design of scissor arm helps to evenly distribute the weight of the user to a larger area, reduces the local pressure, improves the comfort, and can be folded or retracted when not in use, thereby saving space, which is especially important for home use or office environment.

[0056] In the embodiment of the utility model, the scissor arm assembly 310 is configured as two groups, and the two groups of scissor arm assemblies 310 are arranged on opposite sides between the first frame body 100 and the second frame body 200.

[0057] Adopt the above setting, two groups of scissor arm assemblies 310 are distributed on opposite sides, which can provide a more stable support structure, reduce the possibility of tilting and shaking, and thus improve the stability of the overall structure.

[0058] Of course, in other embodiments, the scissor arm assembly 310 described above can also be provided in one group, three groups, etc., which are not limited here.

[0059] With reference to Figures 1 to 3 In the embodiment of the utility model, the scissor arm mechanism 300 further comprises a first linkage plate 330, one end of the first linkage plate 330 is connected with the first scissor arm 311 of one group of scissor arm assemblies 310, and the other end of the first linkage plate 330 is connected with the first scissor arm 311 of another group of scissor arm assemblies 310.

[0060] The output end of the first driving mechanism 400 is in transmission connection with the middle part of the first linkage plate 330.

It can be understood that after the second frame body 200 is driven to move up and down by the first driving mechanism 400, the highest position of the second frame body 200 is the highest position of the second frame body 200 driven upward by the second driving mechanism 500; the transmission sleeve 430 is rotatably connected with the scissor arm mechanism 300, and it can be understood that the first linkage plate 330 of the scissor arm mechanism 300 is provided with a mounting shaft 331, and the transmission sleeve 430 is rotatably arranged on the first linkage plate 330 through the mounting shaft 331, so that when the second driving mechanism 500 drives the scissor arm mechanism 300 to act, it will not affect the first driving mechanism 400.

[0064] The transmission screw 420 can be driven by the first driving motor 410 to achieve precise height adjustment. The screw structure of the screw ensures that the rotary motion can be smoothly and accurately converted into linear motion, so that the height adjustment of the second frame body 200 is very precise.

The auxiliary structure 600 can help stabilize the movement of the scissor arm mechanism 300, reduce vibration and sway, and thus improve the stability of the entire dynamic rack. By sharing part of the work through the auxiliary structure 600, the load of the second driving mechanism 500 can be reduced, prolonging the service life. The auxiliary structure 600 can serve as a safety measure, for example, when the second driving mechanism 500 fails, the auxiliary structure 600 can act as a buffer or support to prevent accidents.

[0068] Specifically, with reference to Figures 1 to 3 In this embodiment, the auxiliary structure 600 includes a connecting plate 610, a connecting column 620 and an elastic member 630, the connecting plate 610 is fixedly connected with the first frame body 100, one end of the connecting column 620 is fixedly connected with the connecting plate 610, the other end of the connecting column 620 is slidably connected with the scissor arm mechanism 300; the elastic member 630 is arranged on the connecting column 620, and one end of the elastic member 630 abuts against the connecting plate 610, and the other end of the elastic member 630 abuts against the scissor arm mechanism 300.

[0069] With the above structure, the connecting plate 610, the connecting column 620 and the elastic member 630 have relatively simple structures, which are convenient for inspection and maintenance; the elastic member 630 not only assists the second driving mechanism 500 to drive the scissor arm mechanism 300 to act through its tensile state, but also absorbs and buffers the vibration generated by the scissor arm mechanism 300 during movement, reduces the impact on the first frame body 100 and the second frame body 200, and improves the durability of the overall structure; the design of the auxiliary structure 600 not only improves the stability and safety of the operation of the scissor arm mechanism 300, but also enhances the overall performance and durability of the system, providing users with a more comfortable and reliable use experience.

[0070] It should be noted that in the embodiment, the elastic member 630 is a cylindrical spring, which is simple in structure and low in production cost.

[0073] Wherein, the rotation center line of the partial structure of transmission rocker arm 530 and eccentric shaft 520 cooperation and the rotation center line of the partial structure of second drive motor 510 output and eccentric shaft 520 cooperation do not coincide.

[0074] With the above structure, due to the design of eccentric shaft 520, the rotary motion generated by second drive motor 510 is converted into eccentric motion, thereby generating periodic torque on transmission shaft 540, which is transmitted to scissor arm mechanism 300, so that scissor arm mechanism 300 acts, and drives second frame body 200 to reciprocate up and down relative to first frame body 100, which is compact in structure and provides flexible, efficient and accurate motion control.
