Description

Technical Field

[0001] This utility model relates to the field of lifting mechanism technology, and more specifically, to a lifting component and an automatic mobile device. Background Technology

[0002] Currently, in related technologies, the crank-connecting rod lifting mechanism consists of a reducer connected to a crank, which drives the connecting rod to achieve the lifting function. During the lifting process, the load generated by the lifting mechanism is transmitted to the crank through the connecting rod, and then from the crank to the reducer output shaft. This causes the output shaft to bear a radial force, which leads to a certain deformation of the output shaft, thereby increasing the wear of the output shaft during operation. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this utility model proposes a lifting assembly.

[0005] The second aspect of this utility model proposes an automatic mobile device.

[0006] In view of the above, the first aspect of this utility model provides a lifting assembly, including a drive assembly, a crank, a first connecting rod, a platform assembly, a support component, and a rolling component; the drive assembly includes an output shaft; the crank is connected to the output shaft; one end of the first connecting rod is rotatably connected to the crank; the platform assembly is rotatably connected to the other end of the first connecting rod; the support component is provided with a guide groove; the rolling component is disposed in the guide groove and connected to the crank; wherein, when the drive assembly drives the platform assembly to rise or fall through the crank and the first connecting rod, the rolling component moves along the guide groove.

[0007] The lifting assembly provided by this utility model includes a support component and a rolling component. The support component is provided with a guide groove, and the rolling component is disposed within the guide groove and connected to a crank. The support component not only supports the rolling component but also allows the rolling component to move more stably and flexibly within the guide groove. When it is necessary to control the platform assembly to rise or fall, the weight of the platform assembly itself and the weight of the goods placed on the platform assembly are transmitted to the crank through the first connecting rod, causing the crank to experience a radial force. Since the rolling component is connected to the crank, the support component can support the crank through the rolling component. The supporting force of the support component on the crank offsets part of the radial force from the platform assembly, reducing the radial force transmitted from the crank to the output shaft, thereby reducing the deformation of the output shaft, reducing wear on the output shaft during power output, and extending the service life of the output shaft.

[0008] Because the lifting assembly reduces the deformation of the output shaft by incorporating support and rolling components, the positional accuracy of the crank and the first connecting rod is improved. This, in turn, enhances the fit between the crank and the first connecting rod, as well as the fit between the crank and the output shaft. It also reduces friction between the crank and the first connecting rod and between the crank and the output shaft, extending their service life. Furthermore, it makes the relative movement between the output shaft, crank, and first connecting rod smoother, reducing energy loss caused by friction between components and improving power transmission efficiency.

[0009] By reducing the friction between the crank and the first connecting rod, as well as the friction between the crank and the output shaft, the noise generated by the friction between the various components during the operation of the lifting assembly is also reduced, thus improving the quietness of the lifting assembly during operation.

[0010] Because the lifting assembly can reduce the deformation of the output shaft by setting up support components and rolling components, the additional bending moment borne by the drive assembly is reduced, especially the additional bending moment borne by the reducer at the output end of the drive assembly, and the radial force borne by the reducer is reduced.

[0011] In some technical solutions of this utility model, optionally, the crank includes a crank body and a first connecting shaft, the crank body is connected to the output shaft; the first connecting shaft is connected to the crank body and to the first connecting rod, and the first connecting shaft is offset relative to the output shaft; the rolling component is connected to the end of the first connecting shaft away from the crank body.

[0012] In this technical solution, the crank includes a crank body connected to an output shaft, allowing the output shaft to transmit power through the crank body. The crank also includes a first connecting shaft connected to the crank body and a first connecting rod, allowing power to be transmitted to the first connecting rod through the crank body and the first connecting shaft. During crank movement, the crank body rotates around the axis of the output shaft, and the first connecting shaft also moves around the axis of the output shaft along with the crank body. Because the first connecting shaft is offset relative to the output shaft, its axis is not collinear with the output shaft's axis, resulting in a certain linear displacement when the first connecting shaft rotates. This linear displacement is transmitted to the platform assembly through the first connecting rod, driving the platform assembly and improving the smoothness of the platform assembly during lifting and lowering.

[0013] Furthermore, a shaft hole is provided at one end of the first connecting rod, and the first connecting shaft passes through the shaft hole of the first connecting rod.

[0014] In some technical solutions of this utility model, optionally, the rolling component is annular and sleeved on the first connecting shaft, and the rolling component is rotatable relative to the first connecting shaft.

[0015] In this technical solution, the rolling component is annular and sleeved on the first connecting shaft. The rolling component can rotate relative to the first connecting shaft, making the friction between the rolling component and the inner wall of the guide groove rolling friction. This reduces the frictional force between the rolling component and the inner wall of the guide groove, thereby reducing wear between the inner wall of the guide groove and the rolling component, improving the fit accuracy between the guide groove and the rolling component, and allowing the support component to more effectively support the crank. Furthermore, the rotation of the rolling component relative to the first connecting shaft makes the fit between the crank and the rolling component more flexible, further improving the smoothness of the crank during rotation.

[0016] In some technical solutions of this utility model, optionally, the rolling component is fixed to the first connecting shaft.

[0017] In this technical solution, the rolling component is fixed to the first connecting shaft, making the connection between the rolling component and the first connecting shaft more stable. The supporting component can support the first connecting shaft more effectively through the rolling component. The supporting component can counteract a larger radial force, thereby reducing the radial force transmitted from the crank to the output shaft, and further reducing the deformation and wear of the output shaft.

[0018] In some technical solutions of this utility model, optionally, the rolling component includes a first rolling part and a second rolling part; the first rolling part is sleeved on the first connecting shaft; the second rolling part is sleeved on the first rolling part and can rotate relative to the first rolling part, and the second rolling part contacts the inner wall of the guide groove.

[0019] In this technical solution, the rolling component includes a first rolling part and a second rolling part. The first rolling part is sleeved on the first connecting shaft, and the second rolling part is sleeved on the first rolling part. During crank rotation, the first rolling part is fixed relative to the first connecting shaft, allowing the support component to more effectively support the first connecting shaft through the first rolling part. The support component can counteract a larger radial force, thereby reducing the radial force transmitted from the crank to the output shaft, further reducing the deformation and wear of the output shaft. The second rolling part rotates relative to the first rolling part and relative to the guide groove, further improving the flexibility of the fit between the rolling component and the guide groove. Furthermore, the cooperation between the first and second rolling parts prevents sliding wear between the rolling component and the first connecting shaft. After the lifting assembly has been in operation for a certain period, even if significant wear occurs, only the first and second rolling parts need to be replaced, without replacing the crank. This reduces the maintenance cost and difficulty of the lifting assembly and improves the convenience of maintenance.

[0020] In some technical solutions of this utility model, optionally, the guide groove is annular, the axis of the guide groove is the first axis, and the axis of the output shaft is the second axis; the first axis and the second axis are collinear.

[0021] In this technical solution, the axis of the guide groove is collinear with the axis of the output shaft, which makes the crank rotate more smoothly during the power transmission process, further reducing the frictional loss between the crank and the output shaft, as well as the frictional loss between the crank and the first connecting rod.

[0022] Optionally, in some technical solutions of this utility model, the support component is provided with a shielding part, which is arranged along the outer periphery of the guide groove and located on the side of the rolling component close to the drive assembly.

[0023] In this technical solution, the support component is provided with a shielding part, which is arranged along the outer periphery of the guide groove and located on the side of the rolling component close to the drive assembly. This shielding part limits the movement of the rolling component, prevents the rolling component from leaving the guide groove, and improves the stability of the rolling component during movement.

[0024] Optionally, in some technical solutions of this utility model, the lifting assembly further includes a base, and the drive assembly, platform assembly and support components are all disposed on the base.

[0025] In this technical solution, the lifting assembly also includes a base, and the drive assembly, platform assembly and support components are all set on the base. The base supports the drive assembly, platform assembly and support components, thereby improving the stability of the lifting assembly during operation.

[0026] Optionally, in some technical solutions of this utility model, the platform assembly includes a second link, a third link, and a lifting platform; one end of the second link is rotatably connected to the base; one end of the third link is rotatably connected to the other end of the second link; and the lifting platform is rotatably connected to the other end of the third link.

[0027] In this technical solution, the platform assembly includes a second link, a third link, and a lifting platform. One end of the second link is rotatably connected to the base, allowing the second link to rotate relative to the base. One end of the third link is rotatably connected to the other end of the second link, allowing the third link to rotate relative to the second link. The lifting platform is rotatably connected to the other end of the third link, allowing the third link to rotate relative to the lifting platform.

[0028] When the lifting platform is in its initial position, the angle between the second link and the base is small, and the second link is nearly horizontal. The angle between the third link and the second link is also small, and the third link is also nearly horizontal. As the lifting platform rises, the angle between the second link and the base gradually increases, and the angle between the third link and the second link gradually increases, thus driving the lifting platform to rise. As the lifting platform descends, the angle between the second link and the base gradually decreases, and the angle between the third link and the second link gradually decreases, thus driving the lifting platform to descend, ensuring the stability of the lifting platform during the rising and falling processes.

[0029] Optionally, in some technical solutions of this utility model, the platform assembly further includes a second connecting shaft, which passes through the second link and / or the third link, and is rotatably connected to the first link.

[0030] In this technical solution, the platform component also includes a second connecting shaft, which passes through the second link and / or the third link, and is rotatably connected to the first link, so that the first link can transmit power to the platform component through the second connecting shaft, thereby realizing the driving of lifting and lowering the platform component.

[0031] The second aspect of this utility model provides an automatic mobile device, including a lifting component as described in any of the above technical solutions; therefore, the automatic mobile device possesses all the beneficial effects of the lifting component as described in any of the above technical solutions.

[0032] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0042] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] The following reference Figures 1 to 6 This invention describes a lifting assembly and an automated moving device according to some embodiments of the present invention.

[0045] In one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a lifting assembly is provided, including a drive assembly 100, a crank 200, a first connecting rod 300, a platform assembly 400, a support component 500, and a rolling component 600. The drive assembly 100 includes an output shaft 110; the crank 200 is connected to the output shaft 110; one end of the first connecting rod 300 is rotatably connected to the crank 200; the platform assembly 400 is rotatably connected to the other end of the first connecting rod 300; the support component 500 is provided with a guide groove 510; the rolling component 600 is disposed in the guide groove 510 and connected to the crank 200; wherein, when the drive assembly 100 drives the platform assembly 400 to rise or fall via the crank 200 and the first connecting rod 300, the rolling component 600 moves along the guide groove 510.

[0046] In this embodiment, the lifting assembly includes a drive assembly 100, a crank 200, a first connecting rod 300, and a platform assembly 400. The drive assembly 100 includes an output shaft 110, the crank 200 is connected to the output shaft 110, one end of the first connecting rod 300 is rotatably connected to the crank 200, and the platform assembly 400 is rotatably connected to the other end of the first connecting rod 300. When it is necessary to control the platform assembly 400 to rise, the drive assembly 100 outputs power through the output shaft 110, and the power is then transmitted to the platform assembly 400 through the crank 200 and the first connecting rod 300, thereby driving the platform assembly 400 to rise. When it is necessary to control the platform assembly 400 to fall, the drive assembly 100 outputs power in the opposite direction through the output shaft 110 (opposite to the direction of the power output by the drive assembly 100 when controlling the platform assembly 400 to rise), and the power is then transmitted to the platform assembly 400 through the crank 200 and the first connecting rod 300, thereby driving the platform assembly 400 to fall.

[0047] The lifting assembly also includes a support component 500 and a rolling component 600. The support component 500 is provided with a guide groove 510, and the rolling component 600 is disposed within the guide groove 510 and connected to the crank 200. The support component 500 supports the rolling component 600 while also allowing the rolling component 600 to move more stably and flexibly within the guide groove 510. When it is necessary to control the platform assembly 400 to rise or fall, the weight of the platform assembly 400 itself and the weight of the goods placed on the platform assembly 400 are transmitted to the crank 200 through the first connecting rod 300, causing the crank 200 to be subjected to a radial force. Since the rolling component 600 is connected to the crank 200, the support component 500 can support the crank 200 through the rolling component 600. The supporting force of the support component 500 on the crank 200 will offset part of the radial force from the platform assembly 400, thereby reducing the radial force transmitted from the crank 200 to the output shaft 110, which in turn reduces the deformation of the output shaft 110, reduces the wear of the output shaft 110 during the power output process, and extends the service life of the output shaft 110.

[0048] Because the lifting assembly reduces the deformation of the output shaft 110 by setting the support component 500 and the rolling component 600, the positional accuracy of the crank 200 and the first connecting rod 300 is also improved, thereby improving the matching accuracy of the crank 200 and the first connecting rod 300, as well as the matching accuracy of the crank 200 and the output shaft 110. This reduces the friction between the crank 200 and the first connecting rod 300 and the output shaft 110, extending the service life of the crank 200 and the first connecting rod 300. Furthermore, it makes the relative movement between the output shaft 110, the crank 200 and the first connecting rod 300 smoother, reducing energy loss caused by friction between components and improving the efficiency of power transmission.

[0049] Because the friction between the crank 200 and the first connecting rod 300 is reduced, as well as the friction between the crank 200 and the output shaft 110 is reduced, the noise generated by the friction between the various components during the operation of the lifting assembly is also reduced, thus improving the quietness of the lifting assembly during operation.

[0050] Since the lifting assembly can reduce the deformation of the output shaft 110 by setting the support component 500 and the rolling component 600, the additional bending moment borne by the drive assembly 100 is reduced, especially the additional bending moment borne by the reducer at the output end of the drive assembly 100, and the radial force borne by the reducer is reduced.

[0051] Furthermore, the drive assembly 100 includes a drive component and a reducer. The drive component and the reducer can be an integrated structure, such as a geared motor, or the drive component and the reducer can be two separate devices, such as a motor as the drive component, the motor being connected to the input shaft of the reducer, and the output shaft 110 of the reducer being connected to the crank 200, thereby realizing the output of power.

[0052] Furthermore, the support component 500 is disposed on the side of the first connecting rod 300 away from the drive assembly 100, so that the output shaft 110 and the support component 500 can support the crank 200 on both sides of the crank 200 and the first connecting rod 300, making the force at the connection between the crank 200 and the first connecting rod 300 more balanced, and further reducing the wear between the first connecting rod 300, the crank 200 and the output shaft 110.

[0053] This embodiment provides a lifting assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, the crank 200 includes a crank body 210 and a first connecting shaft 220. The crank body 210 is connected to the output shaft 110. The first connecting shaft 220 is connected to the crank body 210 and to the first connecting rod 300. The first connecting shaft 220 is offset relative to the output shaft 110. The rolling component 600 is connected to the end of the first connecting shaft 220 away from the crank body 210.

[0055] In this technical solution, the crank 200 includes a crank body 210, which is connected to the output shaft 110, allowing the output shaft 110 to transmit power through the crank body 210. The crank 200 also includes a first connecting shaft 220, which is connected to the crank body 210 and to the first connecting rod 300, allowing power to be transmitted to the first connecting rod 300 through the crank body 210 and the first connecting shaft 220. During the movement of crank 200, crank body 210 rotates around the axis of output shaft 110, and first connecting shaft 220 also moves around the axis of output shaft 110 along with crank body 210. Since the first connecting shaft 220 is offset relative to output shaft 110, the axis of the first connecting shaft 220 and the axis of output shaft 110 will not be collinear. As a result, a certain linear displacement will be generated when the first connecting shaft 220 rotates. This linear displacement is transmitted to platform assembly 400 through first connecting rod 300, thereby driving platform assembly 400 and improving the smoothness of platform assembly 400 during lifting.

[0056] Furthermore, a flange is provided on the output shaft 110, and the handle 210 is connected to the flange, for example, by bolts to fix the handle 210 to the flange, so that the output shaft 110 can drive the crank 200 to rotate, and the output shaft 110 and the crank 200 are relatively fixed.

[0057] A shaft hole may also be provided on the side of the handle 210 away from the first connecting shaft 220. The output shaft 110 passes through the shaft hole, and the pin passes through the handle 210 and the first connecting shaft 220 simultaneously along the radial direction of the output shaft 110, so that the output shaft 110 can drive the crank 200 to rotate, and the output shaft 110 and the crank 200 are relatively fixed.

[0058] A shaft hole may also be provided on the side of the handle 210 away from the first connecting shaft 220, and the output shaft 110 passes through the shaft hole. A set screw or bolt passes radially through the handle 210 and abuts against the output shaft 110, so that the output shaft 110 can drive the crank 200 to rotate, and the output shaft 110 and the crank 200 are relatively fixed. Power can also be transmitted between the handle 210 and the output shaft 110 through the cooperation of a key and a groove.

[0059] Furthermore, the handle 210 and the first connecting shaft 220 can be an integral structure or a separate structure.

[0060] Furthermore, one end of the first connecting rod 300 is provided with a shaft hole, and the first connecting shaft 220 passes through the shaft hole of the first connecting rod 300.

[0061] Specifically, when it is necessary to control the platform component 400 to rise or fall, the weight of the platform component 400 itself and the weight of the goods placed on the platform component 400 will be transmitted to the first connecting shaft 220 through the first link 300, so that the first connecting shaft 220 is subjected to a radial force. The direction of the line connecting the contact point between the rolling component 600 and the inner wall of the guide groove 510 and the axis of the first connecting shaft 220 is the first direction. The component of the radial force on the first connecting shaft 220 in the first direction can be offset by the supporting force of the supporting component.

[0062] This embodiment provides a lifting assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0063] like Figure 3 As shown, the rolling component 600 is annular and sleeved on the first connecting shaft 220, and the rolling component 600 is rotatable relative to the first connecting shaft 220.

[0064] In this technical solution, the rolling component 600 is annular and sleeved on the first connecting shaft 220. The rolling component 600 can rotate relative to the first connecting shaft 220, making the friction between the rolling component 600 and the inner wall of the guide groove 510 rolling friction. This reduces the frictional force between the rolling component 600 and the inner wall of the guide groove 510, thereby reducing wear between the inner wall of the guide groove 510 and the rolling component 600, improving the fit accuracy between the guide groove 510 and the rolling component 600, and allowing the support component 500 to more effectively support the crank 200. Furthermore, the rotation of the rolling component 600 relative to the first connecting shaft 220 makes the fit between the crank 200 and the rolling component 600 more flexible, further improving the smoothness of the crank 200 during rotation.

[0065] Specifically, the rolling component 600 is a roller.

[0066] This embodiment provides a lifting assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0067] The rolling component 600 is fixed to the first connecting shaft 220.

[0068] In this technical solution, the rolling component 600 is fixed to the first connecting shaft 220, making the connection between the rolling component 600 and the first connecting shaft 220 more stable. The support component 500 can more effectively support the first connecting shaft 220 through the rolling component 600. The support component can offset a larger radial force, thereby reducing the radial force transmitted from the crank 200 to the output shaft 110, and further reducing the deformation and wear of the output shaft 110.

[0069] Furthermore, the rolling component 600 may be spherical and fixed to the end of the first connecting shaft 220. The rolling component 600 may also be annular and fixed to the end of the first connecting shaft 220. Alternatively, the rolling component 600 may be disc-shaped and fixed to the end of the first connecting shaft 220.

[0070] The rolling component 600 and the first connecting shaft 220 can be either separate or integrated.

[0071] This embodiment provides a lifting assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0072] like Figure 3 and Figure 4 As shown, the rolling component 600 includes a first rolling part 610 and a second rolling part 620; the first rolling part 610 is sleeved on the first connecting shaft 220; the second rolling part 620 is sleeved on the first rolling part 610 and can rotate relative to the first rolling part 610; the second rolling part 620 contacts the inner wall of the guide groove 510.

[0073] In this technical solution, the rolling component 600 includes a first rolling part 610 and a second rolling part 620. The first rolling part 610 is sleeved on the first connecting shaft 220, and the second rolling part 620 is sleeved on the first rolling part 610. During the rotation of the crank 200, the first rolling part 610 is fixed relative to the first connecting shaft 220. The support component 500 can more effectively support the first connecting shaft 220 through the first rolling part 610. The support component can offset a larger radial force, thereby reducing the radial force transmitted from the crank 200 to the output shaft 110, and further reducing the deformation and wear of the output shaft 110. The second rolling part 620 rotates relative to the first rolling part 610 and rotates relative to the guide groove 510, further improving the flexibility of the fit between the rolling component 600 and the guide groove 510. Furthermore, the first rolling part 610 and the second rolling part 620 cooperate to prevent sliding wear between the rolling part 600 and the first connecting shaft 220. After the lifting assembly has been working for a certain period of time, even if there is significant wear, only the first rolling part 610 and the second rolling part 620 need to be replaced, without having to replace the crank 200. This reduces the maintenance cost and difficulty of the lifting assembly and improves the convenience of maintenance.

[0074] Furthermore, the rolling component 600 can be a bearing, with the first rolling part 610 being the inner ring of the bearing and the second rolling part 620 being the outer ring of the bearing.

[0075] The first rolling part 610 and the second rolling part 620 can also be two interlocking ring structures.

[0076] This embodiment provides a lifting assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0077] like Figure 3 and Figure 5 As shown, the guide groove 510 is annular, and the axis of the guide groove 510 is the first axis 512, while the axis of the output shaft 110 is the second axis 112; the first axis 512 and the second axis 112 are collinear.

[0078] In this technical solution, the axis of the guide groove 510 is collinear with the axis of the output shaft 110, which makes the crank 200 rotate more smoothly during the power transmission process, further reducing the frictional loss between the crank 200 and the output shaft 110, as well as reducing the frictional loss between the crank 200 and the first connecting rod 300.

[0079] Specifically, the support component is plate-shaped, and the side wall of the plate-shaped component has an annular guide groove 510, with the opening of the guide groove 510 facing the crank 200.

[0080] This embodiment provides a lifting assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0081] like Figure 5 As shown, the support member 500 is provided with a shielding part 520, which is arranged along the outer periphery of the guide groove 510 and located on the side of the rolling member 600 near the drive assembly 100.

[0082] In this technical solution, the support component 500 is provided with a blocking part 520, which is arranged along the outer periphery of the guide groove 510 and located on the side of the rolling component 600 close to the drive assembly 100. This blocking part 520 limits the rolling component 600, prevents the rolling component 600 from leaving the guide groove 510, and improves the stability of the rolling component 600 during movement.

[0083] Specifically, the shielding part 520 is annular and arranged circumferentially along the guide groove 510.

[0084] There may be multiple shielding parts 520, and the multiple shielding parts 520 are arranged at intervals along the circumference of the guide groove 510.

[0085] Furthermore, the blocking part 520 blocks the outside of the second rolling part 620 but does not contact the first rolling part 610, making the movement of the rolling part 600 within the guide groove 510 smoother.

[0086] This embodiment provides a lifting assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0087] like Figure 3As shown, the lifting assembly also includes a base 700, and the drive assembly 100, platform assembly 400 and support component 500 are all disposed on the base 700.

[0088] In this technical solution, the lifting assembly also includes a base 700. The drive assembly 100, platform assembly 400 and support component 500 are all disposed on the base 700, thereby supporting the drive assembly 100, platform assembly 400 and support component 500 through the base 700, and improving the stability of the lifting assembly during operation.

[0089] This embodiment provides a lifting assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0090] like Figure 3 and Figure 6 As shown, the platform assembly 400 includes a second link 410, a third link 420, and a lifting platform 430; one end of the second link 410 is rotatably connected to the base 700; one end of the third link 420 is rotatably connected to the other end of the second link 410; and the lifting platform 430 is rotatably connected to the other end of the third link 420.

[0091] In this technical solution, the platform assembly 400 includes a second link 410, a third link 420, and a lifting platform 430. One end of the second link 410 is rotatably connected to the base 700, allowing the second link 410 to rotate relative to the base 700. One end of the third link 420 is rotatably connected to the other end of the second link 410, allowing the third link 420 to rotate relative to the second link 410. The lifting platform 430 is rotatably connected to the other end of the third link 420, allowing the third link 420 to rotate relative to the lifting platform 430.

[0092] When the lifting platform 430 is in its initial position, the angle between the second link 410 and the base 700 is small, and the second link 410 is nearly horizontal. The angle between the third link 420 and the second link 410 is also small, and the third link 420 is also nearly horizontal. As the lifting platform 430 rises, the angle between the second link 410 and the base 700 gradually increases, and the angle between the third link 420 and the second link 410 gradually increases, thereby driving the lifting platform 430 to rise. As the lifting platform 430 descends, the angle between the second link 410 and the base 700 gradually decreases, and the angle between the third link 420 and the second link 410 gradually decreases, thereby driving the lifting platform 430 to descend, ensuring the stability of the lifting platform 430 during the rising and falling processes.

[0093] This embodiment provides a lifting assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0094] like Figure 3 and Figure 6 As shown, the platform assembly 400 also includes a second connecting shaft 440, which passes through the second link 410 and / or the third link 420, and is rotatably connected to the first link 300.

[0095] In this technical solution, the platform component 400 also includes a second connecting shaft 440, which passes through the second link 410 and / or the third link 420, and is rotatably connected to the first link 300, so that the first link 300 can transmit power to the platform component 400 through the second connecting shaft 440, thereby realizing the driving of lifting and lowering the platform component 400.

[0096] Specifically, the second link 410 and the third link 420 can form a link assembly. There are four link assemblies in total. Among the four link assemblies, the two link assemblies located on the same side of the lifting platform 430 are connected by a tie rod.

[0097] Both ends of the pull rod can be connected to two sets of second connecting rods 410 respectively; both ends of the pull rod can also be connected to two sets of third connecting rods 420 respectively; both ends of the pull rod can also be connected to the second connecting rod 410 and the third connecting rod 420 simultaneously; the second and third pull rods of the two sets of pull rod assemblies can also be connected by two pull rods respectively; this structure can further improve the stability of the lifting platform 430 during movement.

[0098] Both ends of the second link 410 and the third link 420 are provided with through holes. One end of the second link 410 is rotatably connected to the base 700 through a rotating shaft, and one end of the third link 420 is rotatably connected to the platform through a rotating shaft. The second connecting shaft 440 passes through the shaft holes at the other ends of both the second link 410 and the third link 420, so that the second link 410 and the third link 420 are rotatably connected.

[0099] Specifically, the first connecting rod 300 is provided with a through hole, and the second connecting shaft 440 passes through the through hole of the first connecting rod 300.
