Description

Technical Field

[0001] This application relates to the field of vehicles, and in particular to a lifting fixture, maintenance equipment, and battery swapping station. Background Technology

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. In this context, electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the automotive industry's sustainable development.

[0003] During the vehicle's lifespan, the battery may need to be replaced or repaired. In the process of replacing or repairing the battery, the vehicle usually needs to be lifted. The lifting device typically extends a lifting tray under the vehicle's chassis and lifts the entire vehicle through the chassis. The lifting tray may obstruct the battery, increasing the difficulty of battery replacement or repair. Summary of the Invention

[0004] This application provides a lifting fixture, maintenance equipment, and a battery swapping station, which can lift vehicles and reduce the difficulty of vehicle maintenance.

[0005] In a first aspect, this application provides a lifting fixture, which includes a shaft and a load-bearing assembly. The load-bearing assembly includes a first load-bearing member and a second load-bearing member. The first load-bearing member is rotatably disposed on the shaft and includes a first load-bearing portion and a first limiting portion connected to the first load-bearing portion. The second load-bearing member is disposed on the shaft and includes a second load-bearing portion. The first load-bearing portion and the first load-bearing portion are used to support the tires of a vehicle. The first load-bearing member can be locked relative to the shaft when both the first limiting portion and the first load-bearing portion are abutting against the tires.

[0006] The lifting fixture can lift the tires of a vehicle, thereby reducing obstruction to the vehicle's undercarriage and facilitating vehicle maintenance. A first load-bearing member is rotatably mounted on the axle. When the first load-bearing member is subjected to pressure from the tire, it can rotate around the axle to change the relative position between the first and second load-bearing members, thus adapting to different tire models and improving the fixture's adaptability. While the first load-bearing member is under pressure and rotating around the axle, a first limiting member rotates around the axle and gradually approaches the tire. When both the first limiting member and the first load-bearing member are in contact with the tire, the tire restricts the rotation of the first load-bearing member relative to the axle, allowing the first load-bearing member to stably support the tire. With the first load-bearing member, the second load-bearing member, and the first limiting member all in contact with the tire, there are at least three stress points between the lifting fixture and the tire. This improves the uniformity of force distribution on the tire and enhances the stability of the lifted vehicle.

[0007] In some embodiments, the second carrier is rotatably disposed on the shaft, and the second carrier further includes a second limiting portion connected to the second carrier portion. The second carrier can be locked relative to the shaft when both the second limiting portion and the second carrier portion are abutting against the tire.

[0008] Both the first and second load-bearing components are rotatably mounted on the shaft, which increases the range of relative positional variation between the first and second load-bearing components and improves adaptability. By providing a second limiting component, the number of stress points on the tire can be further increased, improving the uniformity of tire stress and enhancing the stability of the lifted vehicle.

[0009] In some embodiments, when viewed vertically, the first bearing portion and the second bearing portion are located on both sides of the axle to improve the uniformity of the force on the tire.

[0010] In some embodiments, when viewed vertically, the first limiting portion is located on the side of the second bearing portion away from the shaft, and the second limiting portion is located on the side of the first bearing portion away from the shaft. The embodiments of this application can reduce the risk of interference between the first and second bearing members during rotation.

[0011] In some embodiments, when viewed vertically, the first bearing portion and the second bearing portion are symmetrically arranged about the axis, as are the first limiting portion and the second limiting portion. The embodiments of this application can improve the uniformity of force distribution on the tires and enhance the stability of the lifted vehicle.

[0012] In some embodiments, the shaft extends along a first direction, and the first direction, the second direction, and the vertical direction are perpendicular to each other. Viewed along the second direction, the first limiting portion is located above the first bearing portion, and the second limiting portion is located above the second bearing portion. The first and second limiting portions can limit the tire from both sides of the second direction, thereby reducing the risk of vehicle rollover and consequently reducing the risk of injury to maintenance personnel.

[0013] In some embodiments, the first support member includes a first rotating portion, a first connecting portion, and a second connecting portion. The first rotating portion is rotatably connected to the shaft. The first connecting portion connects the first rotating portion and the first support portion. The second connecting portion connects the first rotating portion and the first limiting portion, and the first connecting portion and the second connecting portion are respectively connected to both sides of the first rotating portion.

[0014] In some embodiments, the second carrier includes a second rotating portion, a third connecting portion, a fourth connecting portion, and a second limiting portion. The second rotating portion is rotatably connected to the shaft. The third connecting portion connects the second rotating portion and the second carrier portion. The fourth connecting portion is connected to the second rotating portion, and the third and fourth connecting portions are respectively connected to both sides of the second rotating portion. The second limiting portion is connected to the fourth connecting portion, and the second carrier can be locked relative to the shaft when both the second limiting portion and the second carrier portion are abutting against the tire.

[0015] In some embodiments, the second rotating part is sleeved on the shaft, and the first rotating part is sleeved on the second rotating part. The first rotating part and the second rotating part share a space in the axial direction of the shaft, which can improve space utilization and increase the integration of the load-bearing components.

[0016] In some embodiments, the first carrier further includes a third limiting portion connected to the first limiting portion. The third limiting portion is used to restrict the movement of the tire in a first direction, which is parallel to the axial direction of the axle. By providing the third limiting portion, the movement of the vehicle in the first direction can be reduced, thereby lowering the risk of injury to maintenance personnel.

[0017] In some embodiments, the third limiting part is adjustablely positioned relative to the first limiting part in the first direction. The position of the third limiting part can be adjusted according to the tire model, thereby providing better adaptability to the lifting fixture.

[0018] In some embodiments, the lifting fixture includes two load-bearing components, which are respectively disposed at both ends of the axle. The lifting fixture can support two tires simultaneously to improve the stability of the vehicle being lifted.

[0019] In some embodiments, the axis of the axle is parallel to the lateral direction of the vehicle. The axle does not pass over the vehicle's door sill beams to reduce obstruction of the view under the vehicle and facilitate operation by maintenance personnel.

[0020] In some embodiments, the lifting fixture includes an adapter fixed to a shaft for connection with a lifting device. The lifting device can cooperate with the adapter to lift the vehicle by means of the lifting fixture.

[0021] Secondly, embodiments of this application provide a repair device, which includes a lifting device and a lifting fixture provided in any embodiment of the first aspect. The lifting device is used to lift a vehicle. The lifting fixture is used to be positioned under the vehicle and to support the vehicle's tires.

[0022] Thirdly, embodiments of this application provide a battery swapping station, which includes a lifting device and a lifting fixture provided in any of the embodiments of the first aspect. The lifting device is used to lift the vehicle. The lifting fixture is used to be positioned under the vehicle and to support the vehicle's tires. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0040] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0043] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0044] In this application, "multiple" means two or more (including two).

[0045] In the embodiments of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering.

[0046] During the vehicle's lifespan, the battery may need to be replaced or repaired; and during the replacement or repair of the battery, the vehicle usually needs to be lifted.

[0047] In related technologies, lifting devices typically involve extending a lifting tray under the vehicle's chassis and lifting the entire vehicle via the chassis. However, the lifting tray may obstruct the battery, increasing the difficulty of battery replacement or repair.

[0048] In some embodiments, this application provides a lifting fixture that can lift the tires of a vehicle. Exemplarily, after the lifting device lifts the vehicle, the lifting fixture can be placed under the tires, and then the lifting device places the vehicle on the lifting fixture; at this time, the lifting pallet of the lifting device no longer needs to lift the chassis of the vehicle, that is, the lifting pallet can be detached from the chassis of the vehicle, thereby reducing the obstruction of the battery by the lifting pallet.

[0049] However, the load-bearing components of lifting fixtures used to support the weight of vehicles are usually fixed, and lifting fixtures can only be adapted to a single type of tire.

[0050] Therefore, this application provides a lifting fixture, which includes a shaft and a load-bearing assembly. The load-bearing assembly includes a first load-bearing member and a second load-bearing member. The first load-bearing member is rotatably disposed on the shaft and includes a first load-bearing portion and a first limiting portion connected to the first load-bearing portion. The second load-bearing member is disposed on the shaft and includes a second load-bearing portion. The first load-bearing portion and the first load-bearing portion are used to support the tire of a vehicle. The first load-bearing member can be locked relative to the shaft when both the first limiting portion and the first load-bearing portion are abutting against the tire.

[0051] The first bearing member is rotatably mounted on the shaft. When the first bearing member is subjected to pressure from the tire, it can rotate around the shaft to change the relative position between the first and second bearing members, thereby adapting to the tire model and improving the adaptability of the lifting fixture. When the first bearing member is compressed and rotates around the shaft, the first limiting member rotates around the shaft and gradually approaches the tire. When both the first limiting member and the first bearing member are in contact with the tire, the tire can restrict the rotation of the first bearing member relative to the shaft, thus enabling the first bearing member to stably support the tire. The first bearing member, the second bearing member, and the first limiting member are all in contact with the tire, and there are at least three force points between the lifting fixture and the tire. This can improve the uniformity of the force on the tire and improve the stability of the lifted vehicle.

[0052] The lifting fixture disclosed in this application can be used for vehicle maintenance equipment, battery swapping stations, and other scenarios requiring vehicle lifting.

[0053] The lifting fixtures, maintenance equipment, and battery swapping station of this application are described in detail below with reference to the accompanying drawings.

[0054] Figure 1 This is a schematic diagram of the structure of the lifting tooling provided in some embodiments of this application; Figure 2 for Figure 1 Enlarged view of the area within the circle; Figure 3 for Figure 1 A top view of the lifting fixture shown; Figure 4 for Figure 1 A side view of the lifting fixture shown; Figure 5 for Figure 4 The diagram shows the lifting fixture used to lift the tires of a vehicle.

[0055] Reference Figures 1 to 5 The lifting fixture 100 of this application embodiment includes a shaft 1 and a bearing component 2, with the bearing component 2 disposed on the shaft 1.

[0056] For example, the support component 2 is used to abut against and support the tire 201 of the vehicle 200.

[0057] There may be one or more support components 2. For example, there may be multiple support components 2, which are arranged along the axial direction of the shaft 1.

[0058] In some embodiments, the support assembly 2 includes a first support member 21 and a second support member 22, wherein the first support member 21 is rotatably disposed on the shaft 1 and the second support member 22 is disposed on the shaft 1.

[0059] The support component 2 may include one first support member 21 or multiple first support members 21; the support component 2 may include one second support member 22 or multiple second support members 22.

[0060] The first bearing member 21 can be directly connected to the shaft 1, or it can be indirectly connected to the shaft 1 through other components.

[0061] The second bearing member 22 can be fixedly mounted on the shaft 1 or rotatably mounted on the shaft 1.

[0062] In some embodiments, the first support member 21 includes a first support portion 211, and the second support member 22 includes a second support portion 221. The first support portion 211 and the second support portion 221 are used to support the tire 201 of the vehicle 200.

[0063] For example, the first carrier 21 may include one first carrier portion 211 or multiple first carrier portions 211.

[0064] For example, the first support portion 211 may include a rod-shaped structure, a spherical structure, or other shaped structures.

[0065] For example, the second carrier 22 may include one second carrier portion 221 or multiple second carrier portions 221.

[0066] For example, the second support portion 221 may include a rod-shaped structure, a spherical structure, or other shaped structures.

[0067] For example, the first support member 21 can be a one-piece molded component or a component consisting of multiple independent components fixed together. The second support member 22 can be a one-piece molded component or a component consisting of multiple independent components fixed together.

[0068] In some embodiments, the first carrier 21 includes a first limiting portion 212 connected to the first carrier portion 211. Exemplarily, the first carrier 21 includes one or more first limiting portions 212.

[0069] In some embodiments, the first carrier 21 can be locked relative to the axle 1 when both the first limiting portion 212 and the first carrier portion 211 are abutting against the tire 201.

[0070] For example, locking the first carrier 21 relative to the shaft 1 can mean that "the rotation of the first carrier 21 relative to the shaft 1 is locked".

[0071] The first bearing member 21 is rotatably disposed on the shaft 1. When the first bearing part 211 is subjected to the pressure of the tire 201, the first bearing part 211 can rotate around the shaft 1 to change the relative position between the first bearing part 211 and the second bearing part 221, thereby adapting to the model of the tire 201 and improving the adaptability of the lifting fixture 100. When the first bearing part 211 is pressed and rotates around the shaft 1, the first limiting part 212 rotates around the shaft 1 and gradually approaches the tire 201. When both the first limiting part 212 and the first bearing part 211 are in contact with the tire 201, the tire 201 can restrict the rotation of the first bearing member 21 relative to the shaft 1, thereby enabling the first bearing part 211 to stably support the tire 201. The first bearing part 211, the second bearing part 221 and the first limiting part 212 are all in contact with the tire 201. There are at least three force points between the lifting fixture 100 and the tire 201, which can improve the uniformity of the force on the tire 201 and improve the stability of the lifted vehicle 200.

[0072] For example, the embodiments of this application utilize the mechanical structure of the first bearing member 21 itself to achieve locking, without the need to add power structures such as cylinders and motors, thereby simplifying the structure of the lifting fixture 100.

[0073] In some embodiments, the second support member 22 is rotatably disposed on the shaft 1, and the second support member 22 further includes a second limiting portion 222 connected to the second support portion 221. The second support member 22 can be locked relative to the shaft 1 when both the second limiting portion 222 and the second support portion 221 are abutting against the tire 201.

[0074] For example, the second carrier 22 includes one or more second limiting portions 222.

[0075] For example, locking the second carrier 22 relative to the shaft 1 can mean that "the rotation of the second carrier 22 relative to the shaft 1 is locked".

[0076] Both the first support member 21 and the second support member 22 are rotatably mounted on the shaft 1, which increases the range of relative positional variation between the first support portion 211 and the second support portion 221, improving adaptability. By providing the second limiting portion 222, the number of stress points on the tire 201 can be further increased, improving the uniformity of stress on the tire 201 and enhancing the stability of the lifted vehicle 200.

[0077] In some embodiments, viewed along the vertical direction Z, the first bearing portion 211 and the first limiting portion 212 are located on opposite sides of the shaft 1. When one of the first bearing portion 211 and the first limiting portion 212 is subjected to the pressure of the tire 201 and rotates, the other can move toward the tire 201 until it comes into contact with the tire 201. When the first bearing portion 211 and the first limiting portion 212 are in contact with the tire 201 at the same time, the torque on the first bearing portion 211 is opposite to the torque on the first limiting portion 212. When the torque on the first bearing portion 211 and the torque on the first limiting portion 212 are balanced, the first bearing member 21 stops rotating.

[0078] As an example, the vertical direction Z is parallel to the direction of gravity.

[0079] In some embodiments, viewed along the vertical direction Z, the second bearing portion 221 and the second limiting portion 222 are located on both sides of the shaft 1. When one of the second bearing portion 221 and the second limiting portion 222 is subjected to the pressure of the tire 201 and rotates, the other can move toward the tire 201 until it comes into contact with the tire 201. When the second bearing portion 221 and the second limiting portion 222 are in contact with the tire 201 at the same time, the torque on the second bearing portion 221 is opposite to the torque on the second limiting portion 222. When the torque on the second bearing portion 221 and the torque on the second limiting portion 222 are balanced, the second bearing member 22 stops rotating.

[0080] In some embodiments, when viewed along the vertical direction Z, the first bearing portion 211 and the second bearing portion 221 are located on both sides of the axle 1, so as to improve the uniformity of force on the tire 201.

[0081] In some embodiments, the first limiting portion 212 is located on the side of the second bearing portion 221 away from the shaft 1, and the second limiting portion 222 is located on the side of the first bearing portion 211 away from the shaft 1.

[0082] The embodiments of this application can reduce the risk of interference between the first support member 21 and the second support member 22 during rotation.

[0083] In some embodiments, when viewed along the vertical direction Z, the first bearing portion 211 and the second bearing portion 221 are symmetrically arranged about the shaft 1, and the first limiting portion 212 and the second limiting portion 222 are symmetrically arranged about the shaft 1.

[0084] The embodiments of this application can improve the uniformity of force on the tire 201 and improve the stability of the lifted vehicle 200.

[0085] In some embodiments, the shaft 1 extends along a first direction Y, and the first direction Y, the second direction X, and the vertical direction Z are perpendicular to each other. Viewed along the second direction X, the first limiting part 212 is located above the first bearing part 211, and the second limiting part 222 is located above the second bearing part 221.

[0086] The first limiting part 212 and the second limiting part 222 can limit the tire 201 from both sides in the second direction X, thereby reducing the risk of the vehicle 200 rolling away and thus reducing the risk of injury to maintenance personnel.

[0087] In some embodiments, the first support member 21 includes a first rotating portion 213, a first connecting portion 214, and a second connecting portion 215. The first rotating portion 213 is rotatably connected to the shaft 1. The first connecting portion 214 connects the first rotating portion 213 and the first support portion 211. The second connecting portion 215 connects the first rotating portion 213 and the first limiting portion 212, and the first connecting portion 214 and the second connecting portion 215 are respectively connected to both sides of the first rotating portion 213.

[0088] In some embodiments, the first rotating part 213 includes a bearing.

[0092] In some embodiments, the second connection portion 215 may be one or more.

[0093] In some embodiments, the first limiting portion 212 includes a first limiting rod extending along a first direction Y. The first limiting rod has a rod-like structure and a large contact area with the tire 201.

[0094] In some embodiments, there are multiple second connecting portions 215, which are arranged along the first direction Y. Multiple second connecting portions 215 can improve the structural strength of the first support member 21.

[0095] In some embodiments, the second connecting portion 215 includes a first rod 215a and a second rod 215b that are intersecting. The first rod 215a and the first connecting portion 214 are respectively connected to both sides of the first rotating portion 213; the first rod 215a connects the second rod 215b and the first rotating portion 213, and the first limiting portion 212 is connected to the second rod 215b.

[0096] By setting the first rod 215a and the second rod 215b to intersect, the relative positions of the first limiting part 212 and the first bearing part 211 can be adjusted, making it easy to achieve the balance of the first bearing member 21.

[0097] In some embodiments, the first rod 215a and the second rod 215b form a first preset angle, optionally between 60° and 90°. Optionally, the first rod 215a and the second rod 215b are perpendicular.

[0098] In some embodiments, the first rod 215a and the second rod 215b are welded together.

[0099] In some alternative embodiments, the second connecting portion 215 includes an arc-shaped rod. The arc-shaped rod can replace the intersecting first rod 215a and second rod 215b.

[0100] In some embodiments, the second carrier member 22 includes a second rotating portion 223, a third connecting portion 224, a fourth connecting portion 225, and a second limiting portion 222. The second rotating portion 223 is rotatably connected to the shaft 1. The third connecting portion 224 connects the second rotating portion 223 and the second carrier portion 221. The fourth connecting portion 225 is connected to the second rotating portion 223, and the third connecting portion 224 and the fourth connecting portion 225 are respectively connected to both sides of the second rotating portion 223.

[0101] In some embodiments, the second rotating part 223 includes a bearing.

[0102] In some embodiments, the third connecting part 224 is a rod-shaped structure, and its two ends are respectively connected to the second rotating part 223 and the second bearing part 221.

[0103] In some embodiments, the second support portion 221 includes a second support rod extending along a first direction Y. The second support rod has a rod-like structure and a large contact area with the tire 201.

[0111] In some embodiments, the third rod 225a and the fourth rod 225b are welded together.

[0112] In some alternative embodiments, the fourth connecting portion 225 includes an arc-shaped rod. The arc-shaped rod can replace the intersecting third rod 225a and fourth rod 225b.

[0113] In some embodiments, when viewed along the vertical direction Z, the third connecting portion 224 and the second connecting portion 215 do not overlap, and the first connecting portion 214 and the fourth connecting portion 225 do not overlap.

[0114] In some embodiments, the second rotating part 223 is sleeved on the shaft 1, and the first rotating part 213 is sleeved on the second rotating part 223. The first rotating part 213 and the second rotating part 223 share a space in the axial direction of the shaft 1, which can improve space utilization and increase the integration of the load-bearing component 2.

[0115] In some embodiments, the first support member 21 further includes a third limiting portion 216, which is connected to the first limiting portion 212. The third limiting portion 216 is used to limit the movement of the tire 201 in a first direction Y, which is parallel to the axial direction of the shaft 1.

[0116] As an example, when both the first limiting part 212 and the first bearing part 211 are in contact with the tire 201, the third limiting part 216 overlaps with the tire 201 in the first direction Y.

[0117] By setting the third limiting part 216, the movement of the vehicle 200 in the first direction Y can be reduced, thereby reducing the risk of injury to maintenance personnel.

[0118] In some embodiments, there is one third limiting portion 216. Alternatively, there are two third limiting portions 216, which are spaced apart along the first direction Y.

[0119] In some embodiments, the second carrier 22 may include a fourth limiting portion (not shown), which is connected to the second limiting portion 222. The fourth limiting portion is used to limit the movement of the tire 201 in the first direction Y.

[0120] In some embodiments, the third limiting portion 216 is adjustablely positioned on the first limiting portion 212 in the first direction Y.

[0121] The position of the third limiting part 216 can be adjusted according to the model of the tire 201, so that the lifting fixture 100 has better adaptability.

[0122] As an example, the third limiting portion 216 may be provided with a locking structure for locking with the first limiting portion 212. For example, the locking structure includes a fastener.

[0123] When it is necessary to adjust the position of the third limiting part 216, the locking structure and the first limiting part 212 are released, and then the third limiting part 216 is moved along the first direction Y. When the third limiting part 216 moves to the target position, the locking structure is locked to the first limiting part 212, thereby fixing the first limiting part 212 and the third limiting part 216.

[0124] In some embodiments, the lifting fixture 100 includes two load-bearing components 2, which are respectively disposed at both ends of the shaft 1. The lifting fixture 100 can simultaneously support two tires 201 to improve the stability of the lifted vehicle 200.

[0125] In some embodiments, the axial direction of the shaft 1 is parallel to the lateral direction of the vehicle 200. The shaft 1 does not pass through the door sill beam of the vehicle 200 to reduce obstruction of the view of the bottom of the vehicle 200 and facilitate operation by maintenance personnel.

[0126] In some embodiments, the lifting fixture 100 includes an adapter 3 fixed to the shaft 1, the adapter 3 being used to connect to a lifting device. The lifting device can cooperate with the adapter 3 to lift the vehicle 200 by means of the lifting fixture 100.

[0127] In some embodiments, the lower side of the adapter 3 has a flat surface. The lifting tray of the lifting device can be moved to the lower side of the adapter 3, and a planar contact can be formed between the lifting tray and the adapter 3. The planar contact can increase the friction between the lifting tray and the adapter 3 and reduce the sliding of the adapter 3 on the lifting tray.

[0128] In some embodiments, there are two adapter parts 3, which are respectively connected to the two ends of the shaft 1.

[0129] Figure 6 A schematic diagram of a repair device provided in some embodiments of this application; Figure 7 Another schematic diagram of the repair equipment provided in some embodiments of this application; Figure 8 This is yet another schematic diagram of a repair device provided in some embodiments of this application.

[0130] Reference Figures 5 to 8This application provides a repair device including a lifting device 300 and a lifting fixture 100 provided in any of the foregoing embodiments. The lifting device 300 is used to lift a vehicle 200. The lifting fixture 100 is used to be disposed under the vehicle 200 and to support the tires 201 of the vehicle 200.

[0131] In some embodiments, there are two lifting fixtures 100. One lifting fixture 100 has two load-bearing components 2 for supporting two front tires, and the other lifting fixture 100 has two load-bearing components 2 for supporting two rear tires.

[0132] For example, refer to Figure 6 When the battery of vehicle 200 needs to be replaced or repaired, the lifting tray 301 of the lifting device 300 moves to the underside of vehicle 200, and the lifting tray 301 lifts the sill beam or battery of vehicle 200, thereby lifting vehicle 200 to a certain height.

[0133] Then, place the two load-bearing components 2 of one lifting fixture 100 under the two front tires of the vehicle 200, and place the two load-bearing components 2 of the other lifting fixture 100 under the two rear tires of the vehicle 200.

[0134] Reference Figure 5 and Figure 7 The lifting tray 301 moves downward to lower the tires 201 (front and rear tires) of the vehicle 200. During the descent of the vehicle 200, the tires 201 first contact the first support portion 211 and the second support portion 221, and press down on the first support portion 211 and the second support portion 221.

[0135] Driven by the tire 201, the first carrier 21 and the second carrier 22 rotate, and the first limiting part 212 and the second limiting part 222 rotate and press tightly against the tire 201, thereby locking the tire 201 in the longitudinal direction of the vehicle. The third limiting part 216 can limit the tire 201 in the lateral direction of the vehicle 200.

[0136] The first bearing member 21 and the second bearing member 22 are rotatably disposed on the shaft 1. The first bearing part 211, the second bearing part 221, the first limiting part 212 and the second limiting part 222 can be adapted to different types of tires 201 by rotating around the shaft 1.

[0137] With the lifting fixture 100 already supporting the vehicle 200, the lifting tray 301 can continue to descend and detach from the vehicle 200. The lifting tray 301 no longer obstructs the battery, facilitating battery replacement or maintenance.

[0138] Reference Figure 8If the height of vehicle 200 is insufficient, the lifting pallet 301 can be moved to the underside of the adapter 3. The lifting pallet 301 rises and lifts the adapter 3, thereby lifting vehicle 200 by means of the lifting fixture 100 until the height of vehicle 200 meets the maintenance requirements.

[0139] The adapter 3 is connected to the end of the shaft 1, that is, the adapter 3 is located on the outside of the tire 201; when the adapter 3 is lifted, the overlap between the lifting tray 301 and the vehicle 200 in the vertical direction Z is small, and the lifting tray 301 obstructs the battery less.

[0140] Compared to the solution of directly using the lifting tray 301 to lift the sill beam, the embodiment of this application uses two lifting fixtures 100 to lift the front tire and the rear tire respectively, thereby freeing up the space under the vehicle and making the operation more convenient.

[0141] This application embodiment also provides a battery swapping station, which includes a lifting device 300 and a lifting fixture 100 provided in any of the foregoing embodiments. The lifting device 300 is used to lift the vehicle 200. The lifting fixture 100 is used to be disposed under the vehicle 200 and to support the tires 201 of the vehicle 200.

[0142] For example, the battery swapping station can lift vehicle 200 in the same way as maintenance equipment. Once vehicle 200 is lifted to a set height, the battery is removed and a new fully charged battery is installed.

[0143] Reference Figures 1 to 8 This application provides a lifting fixture 100, which includes a shaft 1, two load-bearing components 2 and two adapters 3.

[0144] The shaft 1 extends along the first direction Y, and two connecting parts 3 are respectively connected to the two ends of the shaft 1 along the first direction Y.

[0145] Two load-bearing components 2 are disposed on the shaft 1, and the two load-bearing components 2 are spaced apart along the first direction Y.

[0146] The support assembly 2 includes a first support member 21 and a second support member 22. The first support member 21 includes a first support portion 211, a first limiting portion 212, a first rotating portion 213, a first connecting portion 214, and a second connecting portion 215. The second support member 22 includes a second support portion 221, a second limiting portion 222, a second rotating portion 223, a third connecting portion 224, and a fourth connecting portion 225.

[0147] The first rotating part 213 is rotatably disposed on the shaft 1. The first connecting part 214 connects the first rotating part 213 and the first bearing part 211. The second connecting part 215 connects the first rotating part 213 and the first limiting part 212, and the first connecting part 214 and the second connecting part 215 are respectively connected to both sides of the first rotating part 213.

[0148] The second rotating part 223 is rotatably connected to the shaft 1. The third connecting part 224 connects the second rotating part 223 and the second bearing part 221. The fourth connecting part 225 connects the second rotating part 223 and the second limiting part 222, and the third connecting part 224 and the fourth connecting part 225 are respectively connected to both sides of the second rotating part 223.

[0149] Viewed along the vertical direction Z, the first bearing portion 211 and the second bearing portion 221 are located on both sides of the shaft 1. The first limiting portion 212 is located on the side of the second bearing portion 221 away from the shaft 1, and the second limiting portion 222 is located on the side of the first bearing portion 211 away from the shaft 1.

[0150] The first direction Y, the second direction X, and the vertical direction Z are perpendicular to each other. When viewed along the second direction X, the first limiting part 212 is located above the first bearing part 211, and the second limiting part 222 is located above the second bearing part 221.

[0151] For example, the first carrier 21 can be locked relative to the axle 1 when both the first limiting portion 212 and the first carrier portion 211 are abutting against the tire 201. The second carrier 22 can be locked relative to the axle 1 when both the second limiting portion 222 and the second carrier portion 221 are abutting against the tire 201.

[0152] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
