[0042] This utility model provides a lifting device; please refer to [reference needed]. Figures 1 to 12 The lifting device includes a lifting assembly 100, which includes a support assembly 10, which is movably arranged in a vertical direction for lifting one tire of a vehicle.

[0043] The support assembly 10 includes two support portions 11 distributed along a preset horizontal direction, which together support one tire of the vehicle; at least one support portion 11 of the support assembly 10 is movably arranged along the preset horizontal direction to adjust the distance between the two support portions 11 in the preset horizontal direction, so that the support assembly 10 can be adapted to tires of different diameters.

[0044] The lifting assembly 100 also includes an identification component, at least a portion of which is disposed on the support assembly 10. The identification component identifies the position of the tire to be lifted in a preset horizontal direction and the diameter of the tire, adjusting the position of the support portion 11 along the preset horizontal direction based on the identification result. The identification result includes the position of the tire to be lifted in the preset horizontal direction and the diameter of the tire. By providing the identification component, the position of the tire to be lifted in the preset horizontal direction and the diameter of the tire are automatically identified.

[0045] Since at least a portion of the identification component is disposed on the support component 10, when the support component 10 moves in the vertical direction, the portion of the identification component disposed on the support component 10 moves together in the vertical direction.

[0046] Specifically, in the case where one support portion 11 of the support assembly 10 is movably disposed along a preset horizontal direction, while the other support portion 11 is immovable along the preset horizontal direction, the two support portions 11 of the support assembly 10 are respectively a first support portion 1101 and a second support portion 1102. The first support portion 1101 is movably disposed along the preset horizontal direction, while the second support portion 1102 is immovable along the preset horizontal direction. First, the tire to be lifted is moved to a suitable position in the preset direction, such as... Figure 8 As shown, the tire to be lifted is located near one side of the support assembly 10 in the first horizontal direction, which is perpendicular to the preset horizontal direction. Then, the support assembly 10 is moved along the first horizontal direction towards the tire to be lifted, so that the two support parts 11 are positioned correspondingly to the tire to be lifted in the first horizontal direction. Figure 9 As shown, at this point, the two support parts 11 and the tire to be lifted are distributed along a preset horizontal direction, and the two support parts 11 are located on both sides of the tire to be lifted; then the vehicle to be lifted is moved along the preset horizontal direction so that the second support part 1102 is located under the tire to be lifted, as shown. Figure 10 As shown; then the first support part 1101 is moved along a preset horizontal direction so that the first support part 1101 is positioned below the tire to be lifted, as shown. Figure 11 As shown, both support parts 11 are located below the tire to be lifted, so that the tire to be lifted can be lifted.

[0047] Specifically, in the case where both support portions 11 of the support assembly 10 are movably arranged along a preset horizontal direction, the tire to be lifted is first moved to a suitable position in the preset direction, such as... Figure 8 As shown, the tire to be lifted is located near one side of the support assembly 10 in the first horizontal direction. The support assembly 10 is then moved along the first horizontal direction towards the tire to be lifted, so that the two support portions 11 are positioned correspondingly to the tire to be lifted in the first horizontal direction. Figure 9 As shown, at this point, the two support parts 11 and the tire to be lifted are distributed along a preset horizontal direction, and the two support parts 11 are located on both sides of the tire to be lifted; then, both support parts 11 are moved along the preset horizontal direction so that both support parts 11 are located below the tire to be lifted, as shown. Figure 11 As shown, this enables the two support parts 11 to perform a lifting action on the tire to be lifted.

[0048] Figures 8 to 11 The horizontal direction in the middle is the first horizontal direction. Figures 8 to 11 The vertical direction in the text is the preset horizontal direction. Figures 8 to 11 Tire 200 is the tire to be lifted.

[0049] Specifically, the support assembly 10 is movably arranged along a first horizontal direction. After the vehicle inspection and maintenance are completed, and after the support assembly 10 lowers the tire to the ground, both support parts 11 of the support assembly 10 are moved away from the tire in a preset horizontal direction, and the support assembly 10 is moved along the first horizontal direction and in a direction away from the tire to avoid subsequent movement of the vehicle.

[0050] Since at least a portion of the identification component is disposed on the support component 10, when the support component 10 moves along the first horizontal direction, the portion of the identification component disposed on the support component 10 moves together along the first horizontal direction.

[0054] Specifically, the connecting part 13 is movably arranged relative to the movable part 22 along the first horizontal direction, so as to realize that the entire supporting component 10 is movably arranged relative to the movable part 22 along the first horizontal direction.

[0055] Specifically, at least a portion of the identification component is disposed on the connecting portion 13; therefore, when the supporting component 10 moves in the vertical direction, it drives the portion of the identification component disposed on the connecting portion 13 to move in the vertical direction as well; when the supporting component 10 moves in the first horizontal direction, it drives the portion of the identification component disposed on the connecting portion 13 to move in the first horizontal direction as well.

[0056] Specifically, the lifting column assembly 20 also includes a power component 221, which is connected to the movable component 22 to drive the movable component 22 to move relative to the fixed column 21 in a vertical direction.

The operating state of the drive component 141 includes the start and stop of the drive component 141.

[0081] Specifically, the recognition component includes an imaging element 31, an image recognition module, and a calculation and analysis module. The imaging element 31 is mounted on the support component 10, meaning the support component 10 moves the imaging element 31 together with the imaging element 31 in the vertical and first horizontal directions. The imaging element 31 is used to capture images of the tire to be lifted. The image recognition module is communicatively connected to the imaging element 31 to recognize the image of the tire. The calculation and analysis module is communicatively connected to the image recognition module to determine the position of the tire to be lifted in a preset horizontal direction and the diameter of the tire to be lifted based on the image information recognized by the image recognition module. The control module is communicatively connected to the calculation and analysis module and also to the support component 11 to adjust the position of the support component 11 in the preset horizontal direction based on the position of the tire to be lifted in the preset horizontal direction and the diameter of the tire to be lifted determined by the calculation and analysis module.

[0082] It should be noted that the image information recognized by the image recognition module includes the position and diameter of the tire in the image; the calculation and analysis module calculates the position of the tire to be lifted in the preset horizontal direction and the diameter of the tire to be lifted based on the shooting position and shooting angle of the camera 31, the image information recognized by the image recognition module, the ratio of the tire in the image to the actual tire, etc.

[0083] Specifically, the recognition component includes one or more imaging elements 31; when the recognition component includes multiple imaging elements 31, all multiple imaging elements 31 are communicatively connected to the image recognition module, so that the image recognition module can recognize the tire images captured by the multiple imaging elements 31; the calculation and analysis module is communicatively connected to the image recognition module, so that the calculation and analysis module can determine the position of the tire to be lifted in a preset horizontal direction and the diameter of the tire to be lifted based on the multiple image information recognized by the image recognition module. The tire image captured by each imaging element 31 is used to derive one piece of image information.

[0084] Specifically, the camera element 31 is mounted on the connecting part 13.

[0085] Optionally, the camera component 31 is a webcam or a video camera.

[0086] Alternatively, in a first configuration of the image recognition module and the computational analysis module, the image recognition module, the computational analysis module, and the control module are integrated together to form a control component.

[0087] Optionally, the control components are located on the lifting assembly 100.

[0088] Optionally, the control component is mounted on the support component 10, that is, the control component is mounted on the connecting part 13. The support component 10 drives the control component to move together in the vertical direction and the first horizontal direction.

[0089] Optionally, a second arrangement of the image recognition module and the computational analysis module: the image recognition module and the computational analysis module are integrated together and disposed on the supporting component 10; that is, the image recognition module and the computational analysis module are integrated together and disposed on the connecting part 13. The supporting component 10 drives the integrated module of the image recognition module and the computational analysis module to move together in the vertical direction and the first horizontal direction.

[0090] Optionally, when the image recognition module and the calculation and analysis module are configured in the second configuration, the control module is configured on the lifting assembly 100.

[0091] In this application, the lifting assembly 100 also includes a display 50, which is used to display the recognition result of the recognition assembly.

[0092] Specifically, the display 50 is also used to display information about the lifting height of the tire during the lifting process.

[0093] In this application, a sensing element is provided at a preset position of the support part 11 so that when the sensing element senses the tire, the support part 11 supports the tire and stops moving along a preset horizontal direction.

[0094] Specifically, the support part 11 moves along a preset horizontal direction to gradually move it under the tire. When the support part 11 can stably support the tire, the sensing component detects the tire, causing the support part 11 to stop moving along the preset horizontal direction. For the second support part 1102, which cannot move along the preset horizontal direction, the vehicle to be lifted moves along the preset horizontal direction to gradually move the tire above the second support part 1102. When the second support part 1102 can stably support the tire, the sensing component detects the tire, causing the vehicle to stop moving along the preset horizontal direction.

[0095] Specifically, the sensing component is communicatively connected to the control module so that when the sensing component senses the tire, the control module controls the support part 11 to stop moving in a preset horizontal direction, that is, the control module controls the drive assembly 14 to stop.

[0096] Optionally, the sensing component is an infrared sensor.

[0097] The lifting device of this application automatically adjusts the position of the support 11 in a preset horizontal direction through a control module, an identification component, a drive component 14, and a sensing component, thereby achieving automatic matching of the tire to be lifted and reducing the complexity of manual operation. The lifting device of this application is characterized by high efficiency and intelligence.

[0098] In this application, the fixed column 21 has an installation space 211, and the movable part 22 is movably installed in the installation space 211 in the vertical direction.

[0099] Specifically, the installation space 211 has a sidewall unit, which includes a first inner sidewall 212 and a second inner sidewall 213 disposed opposite to each other. Both the first inner sidewall 212 and the second inner sidewall 213 are provided with preset portions. The lifting assembly 100 also includes a guide pair, which includes two guide members 40 disposed on the movable member 22. The two guide members 40 of the guide pair abut against and slide with the preset portions on the first inner sidewall 212 and the second inner sidewall 213, respectively, so that when the movable member 22 moves vertically, the two guide members 40 of the guide pair slide along the preset portions on the first inner sidewall 212 and the second inner sidewall 213, respectively. Thus, through the cooperation of the two guide members 40 of the guide pair with the preset portions on the first inner sidewall 212 and the second inner sidewall 213, the vertical movement of the movable member 22 can be guided. Furthermore, since the first inner sidewall 212 and the second inner sidewall 213 are arranged opposite to each other, and the two guide members 40 of the guide pair are respectively abutted against the preset part on the first inner sidewall 212 and the preset part on the second inner sidewall 213, the stability of the movable member 22 in the installation space 211 can be ensured in the distribution direction of the first inner sidewall 212 and the second inner sidewall 213, thereby ensuring the stability of the lifting device.

[0100] By sliding the guide member 40 with the preset part, wear on the lifting equipment during lifting can be reduced, thereby increasing the service life of the lifting equipment. The abutment between the guide member 40 and the preset part forms a support between the movable member 22 and the side wall of the installation space 211; each abutment point between the guide member 40 and the corresponding preset part forms a support point.

[0101] In this application, the lifting assembly 100 further includes a guiding mechanism, which includes one or more guiding units, each guiding unit including one or more guiding components; the guiding components include one or more guide pairs, the multiple guide pairs of the guiding components being distributed vertically; the multiple guide components of the guiding units being distributed in a direction perpendicular to the distribution direction of the first inner sidewall 212 and the second inner sidewall 213; the multiple guiding units of the guiding mechanism being distributed circumferentially along the movable member 22. The axial direction of the movable member 22 is parallel to the vertical direction.

[0102] Specifically, multiple guide pairs of the guide assembly are all disposed on one side wall of the movable part 22.

[0103] Optionally, the guide unit includes two guide components, which are respectively disposed on two opposite side walls of the movable member 22.

[0104] Optionally, the two guide elements 40 of each guide pair are distributed in the vertical direction.

[0105] Optionally, in each guide assembly, one of the guide pairs is a set guide pair, wherein the two guide members 40 of the set guide pair are located at the middle and bottom of the movable member 22, respectively, to form a support between the middle of the movable member 22 and the side wall of the mounting space 211, and also to form a support between the bottom of the movable member 22 and the side wall of the mounting space 211.

[0106] like Figures 4 to 6 As shown, the guiding mechanism includes a guiding unit, which includes two guiding components. The two guiding components of the guiding unit are respectively disposed on two opposite side walls of the movable member 22, and each guiding component includes a guide pair group. Figure 6 The two guide elements 40 on the left side form a guide pair, which together form the guide assembly on the left side. Figure 6 The two guide components 40 on the right side form a guide pair, which together form the guide assembly on the right side; the guide assembly on the left side and the guide assembly on the right side together form a guide unit.

[0107] Figure 4 and Figure 5 The active component 22 is Figure 6 A schematic diagram of the two side views of the movable part 22. (See diagram below.) Figure 4 and Figure 5 As shown, for the two guide components, each guide component has a set guide pair; the guides 40 located in the middle of the movable part 22 of the set guide pairs of the two guide components are at the same vertical height, and the guides 40 located at the bottom of the movable part 22 of the set guide pairs of the two guide components are at the same vertical height; by making the vertical distance between the middle guide 40 and the bottom guide 40 larger, the stability of the movable part 22 in the installation space 211 is ensured, thereby ensuring the lifting stability of the lifting equipment.

[0108] like Figures 4 to 6 As shown, the guide members 40 with higher height of the guide pair of the two guide components both cooperate with the first inner sidewall 212, and the guide members 40 with lower height of the guide pair of the two guide components both cooperate with the second inner sidewall 213.

[0109] In this application, multiple guide units of the guide mechanism are arranged in a one-to-one correspondence with multiple sidewall units of the mounting space 211. The multiple sidewall units of the mounting space 211 are distributed circumferentially along the mounting space 211, and the axial direction of the mounting space 211 is parallel to the vertical direction. Multiple guide components of each guide unit are arranged in a one-to-one correspondence with multiple preset units of the corresponding sidewall unit. The multiple preset units of each sidewall unit are distributed in a direction perpendicular to the distribution direction of the first inner sidewall 212 and the second inner sidewall 213. Each preset unit includes one or more preset components, and the multiple preset components of each preset unit are distributed in a direction perpendicular to the distribution direction of the first inner sidewall 212 and the second inner sidewall 213. Each guide pair of each guide component of each guide unit corresponds to one preset component of the corresponding preset unit of the corresponding sidewall unit. The preset component includes the aforementioned preset portion respectively disposed on the first inner sidewall 212 and the second inner sidewall 213.

[0110] like Figure 6 As shown, the installation space 211 has one side wall unit, and the side wall unit has two preset units; each preset unit includes a preset component.

[0111] Optionally, when the guide assembly includes multiple guide pairs, the two guide members 40 of each guide pair are respectively a first guide member and a second guide member; the first guide members of all guide pairs correspond to the first inner sidewall 212, and the second guide members of all guide pairs correspond to the second inner sidewall 213. In this case, at least some of the first guide members of all guide pairs may share a preset portion, which is disposed on the first inner sidewall 212; and / or, at least some of the second guide members of all guide pairs may share a preset portion, which is disposed on the second inner sidewall 213.

[0112] In this application, the first configuration of the guide member 40 and the preset portion is as follows: the guide member 40 is a rolling member 41, and the preset portion is a portion of the wall surface of the first inner sidewall 212 or the second inner sidewall 213. The second configuration of the guide member 40 and the preset portion is as follows: the guide member 40 is a rolling member 41, and the preset portion is a guide groove provided on the first inner sidewall 212 or the second inner sidewall 213. The rolling member 41 is slidably disposed within the guide groove, and the guide member 40 is used to abut against the groove wall surface of the guide groove.

[0113] When the guide member 40 is a rolling member 41, the rolling member 41 is rotatably mounted on the movable member 22 around a preset axis. The preset axis is parallel to both the first inner sidewall 212 and the second inner sidewall 213. The circumferential rolling surface 411 of the rolling member 41 is used to abut against the preset part and is rotatably mounted along the preset part. That is, when the movable member 22 moves in the vertical direction, the rolling member 41 rolls along the preset part. Since the preset part extends in the vertical direction, the rolling member 41 will necessarily roll along the extension direction of the preset part.

[0114] Optionally, guide 40 is a roller.

[0115] Specifically, the rolling element 41 is rotatably mounted on the movable element 22 via the connecting shaft 423, and the central axis of the connecting shaft 423 is a preset axis; that is, the connecting shaft 423 is fixedly mounted on the movable element 22, and the rolling element 41 is rotatably sleeved on the connecting shaft 423.

[0116] Specifically, the rolling element 41 is mounted on the moving element 22 via a connecting assembly, which includes a connecting shaft 423.

[0117] Specifically, such as Figure 12 As shown, the connecting assembly includes a first connector 421 and a second connector 422. The first connector 421 is fixedly mounted on the movable part 22, and the connecting shaft 423 is fixedly mounted on the second connector 422. The first connector 421 and the second connector 422 are detachably connected. After the first connector 421 and the second connector 422 are connected, fasteners are passed through the first connector 421 and the second connector 422 to lock and fix them in place. Optionally, the fasteners are bolts or screws.

[0118] Specifically, the connecting shaft 423 has a connecting end and a free end arranged opposite to each other along its axial direction. The connecting end of the connecting shaft 423 is fixedly connected to the movable member 22, that is, the connecting end of the connecting shaft 423 is fixedly connected to the second connecting member 422. There is a gap between the free end of the connecting shaft 423 and the inner wall of the installation space 211. The free end face of the connecting shaft 423 is provided with a receiving groove 4231. The wear-resistant member 424 is fixedly arranged in the receiving groove 4231, and the wear-resistant member 424 is in contact with the inner wall of the installation space 211. In this way, when the moving part 22 moves vertically, the wear-resistant part 424 slides along the inner wall of the installation space 211. On the one hand, this avoids the free end of the connecting shaft 423 from making hard contact with the inner wall of the installation space 211, which would lead to greater wear and thus improve the service life of the lifting equipment. On the other hand, by having the wear-resistant part 424 contact the inner wall of the installation space 211, the stability of the moving part 22 in the installation space 211 is ensured in the axial direction of the connecting shaft 423, which in turn improves the stability of the moving part 22 in the installation space 211 and thus ensures the lifting stability of the lifting equipment.

[0119] Specifically, wear-resistant part 424 is made of wear-resistant material. Optionally, wear-resistant part 424 is made of plastic. For example, wear-resistant part 424 is made of polymer material.

[0120] Optionally, the wear-resistant part 424 is interference-fitted with the groove wall of the receiving groove 4231.

[0121] Optionally, the receiving groove 4231 is a circular groove; the wear-resistant part 424 is a cylindrical structure.

[0122] Specifically, the mounting space 211 also has a third inner sidewall 214 and a fourth inner sidewall 215 disposed opposite to each other, the distribution direction of the third inner sidewall 214 and the fourth inner sidewall 215 being perpendicular to the distribution direction of the first inner sidewall 212 and the second inner sidewall 213 of the sidewall unit. A gap exists between the free end of the connecting shaft 423 and the third inner sidewall 214 or the fourth inner sidewall 215; the wear-resistant part 424 contacts the third inner sidewall 214 or the fourth inner sidewall 215 so that when the movable part 22 moves in the vertical direction, the wear-resistant part 424 slides along the third inner sidewall 214 or the fourth inner sidewall 215.

[0123] like Figure 6 As shown, the guide assembly has a left-side guide assembly and a right-side guide assembly. The free end of the connecting shaft 423 of the rolling element 41 of the left-side guide assembly has a gap with the third inner wall 214. The wear-resistant part 424 inside the connecting shaft 423 of the rolling element 41 of the left-side guide assembly contacts the third inner wall 214. When the movable part 22 moves vertically, the wear-resistant part 424 inside the connecting shaft 423 of the rolling element 41 of the left-side guide assembly slides along the third inner wall 214 to form a left support. The free end of the connecting shaft 423 of the rolling element 41 of the right-side guide assembly has a gap with the fourth inner wall 215. With a gap, the wear-resistant part 424 inside the connecting shaft 423 of the rolling element 41 of the right guide assembly contacts the fourth inner sidewall 215. When the movable part 22 moves in the vertical direction, the wear-resistant part 424 inside the connecting shaft 423 of the rolling element 41 of the right guide assembly slides along the fourth inner sidewall 215 to form a right support. In this way, the stability of the movable part 22 in the installation space 211 can be guaranteed in the distribution direction of the third inner sidewall 214 and the fourth inner sidewall 215, thereby better ensuring the stability of the movable part 22 in the installation space 211, and thus ensuring the lifting stability of the lifting equipment.

[0124] like Figure 6 As shown, the movable component 22 is supported by the inner wall of the installation space 211 in all directions, ensuring the stability of the movable component 22 within the installation space 211, thereby guaranteeing the accuracy and stability of the lifting equipment. Here, "front and back" refers to... Figure 6 The vertical direction in the middle.

[0125] Specifically, a blocking member 425 is provided on the connecting shaft 423; along the axial direction of the connecting shaft 423, the blocking member 425 is located on the side of the rolling member 41 near the free end of the connecting shaft 423, and the blocking member 425 contacts or clearance fits with the rolling member 41 to limit the rolling member 41 on the connecting shaft 423 and prevent the rolling member 41 from falling off the connecting shaft 423.

[0126] Optionally, the blocking member 425 is a ring-shaped structure; the blocking member 425 is sleeved on the connecting shaft 423. Further, the strip-shaped structure is made to surround the connecting shaft 423 circumferentially, and the two ends of the strip-shaped structure are connected so that the strip-shaped structure forms a ring-shaped blocking member 425.

[0127] Optionally, an annular groove 4232 is provided on the outer peripheral wall of the connecting shaft 423, and the blocking member 425 is disposed in the annular groove 4232.

[0128] In this application, the third arrangement of the guide member 40 and the preset part is as follows: one of the guide member 40 and the preset part is a sliding part, and the other is a slide rail. The sliding part is slidably arranged on the slide rail. One of the sliding part and the slide rail extends in the vertical direction.

[0129] Optionally, the sliding part is a slider, and the slide rail extends vertically. Alternatively, the sliding part is a strip structure extending vertically.

[0130] In this application, the lifting device includes one or more lifting units, and the multiple lifting units are distributed along a preset horizontal direction; the lifting unit includes one or two lifting components 100; when the lifting unit includes two lifting components 100, the two lifting components 100 of the lifting unit are distributed along a first horizontal direction.

[0131] Specifically, when the lifting unit includes two lifting components 100, the lifting unit is a gantry structure.

[0132] Specifically, the number of lifting units in the lifting equipment is the same as the number of rows of tires in the vehicle; that is, one or more lifting units of the lifting equipment are configured in a one-to-one correspondence with one or more rows of tires in the vehicle. Each lifting unit has one or two lifting components 100 that are respectively configured in a one-to-one correspondence with one or two tires in a corresponding row of tires in the vehicle, so that each lifting component 100 of each lifting unit lifts one corresponding tire in the corresponding row of tires in the vehicle. Each row of tires in the vehicle includes one or two tires. For example, a car includes two rows of tires, and each row of tires in a car includes two tires.

[0133] In the specific implementation process, all lifting components 100 of the lifting equipment simultaneously lift all tires of the vehicle to achieve overall lifting of the vehicle.

[0134] Optionally, in this application, the lifting device includes one or more control modules, and all control modules of the lifting device are configured in a one-to-one correspondence with all lifting components 100 of the lifting device.

The lifting component is used to connect with a set part on the structure of the vehicle to be lifted, excluding the tires, so that the lifting component drives the vehicle to move together in the vertical direction through the set part.

[0136] In the specific implementation process, all lifting components 100 of the lifting equipment simultaneously lift all tires of the vehicle, while the lifting mechanism simultaneously lifts other structural parts of the vehicle other than the tires, so as to achieve overall lifting of the vehicle.

[0137] Optionally, the setting location is located at the bottom of the vehicle.

[0138] Specifically, the lifting mechanism includes one or more lifting units, and the multiple lifting units are distributed along a preset horizontal direction; the lifting unit includes one or two lifting column assemblies, and the two lifting column assemblies of the lifting unit are distributed along a first horizontal direction; the lifting column assembly includes a support column and a moving part, and the moving part is movably arranged relative to the support column in a vertical direction.

[0139] Optionally, when the lifting unit includes a lifting column assembly, the moving part forms a lifting element.

[0140] Optionally, when the lifting unit includes two lifting column assemblies, there are two designated locations. The moving parts of the two lifting column assemblies are connected to the two designated locations one-to-one. In this case, the moving parts of the two lifting column assemblies together form a lifting component, and the moving parts of the two lifting column assemblies synchronously lift the two designated locations. Alternatively, when the lifting unit includes two lifting column assemblies, there is one designated location. The moving parts of the two lifting column assemblies are connected to each other via a third connector, which is connected to the designated location. In this case, the moving parts of the two lifting column assemblies and the third connector together form a lifting component.

[0141] Optionally, the support column is provided with a second mating part, and the moving part is provided with a third mating part. The second mating part and the third mating part are slidably mated so that when the moving part moves in the vertical direction, the second mating part and the third mating part slide relative to each other in the vertical direction, so as to guide the movement of the moving part in the vertical direction.

[0142] Optionally, the second mating part adopts the same structure as the preset part, and the third mating part adopts the same structure as the guide member 40.

[0146] The lifting assembly 100 also includes an identification component, at least a portion of which is disposed on the support assembly 10.
