[0003] The present application relates to the field of vehicles, and in particular to a lifting tool, maintenance equipment, and a battery swap station. Background Art

[0004] Energy conservation and emission reduction are the key to the sustainable development of the automotive industry. In this context, electric vehicles have become an important part of the sustainable development of the automotive industry due to their advantages in energy conservation and environmental protection.

[0005] During the life of a vehicle, the battery may need to be replaced or repaired. During the battery replacement or repair process, the vehicle usually needs to be lifted. The lifting device generally extends a lifting tray under the vehicle's chassis and lifts the entire vehicle through the chassis. The lifting tray may obstruct the battery, making battery replacement or repair more difficult.

[0006] Summary of the Invention

[0007] The present application provides a lifting tool, maintenance equipment and battery swap station, which can lift vehicles and reduce the difficulty of vehicle maintenance.

[0008] In a first aspect, the present application provides a lifting fixture comprising an axle and a bearing assembly. The bearing assembly comprises a first bearing member and a second bearing member. The first bearing member is rotatably mounted on the axle, comprising a first bearing portion and a first stopper connected to the first bearing portion. The second bearing member is mounted on the axle and comprises a second bearing portion. The first bearing portion and the second bearing portion are configured to support a vehicle tire. The first bearing member can be locked relative to the axle when both the first stopper and the first bearing portion abut against the tire.

[0009] The lifting fixture can lift the tire of a vehicle, thereby reducing obstruction to the bottom of the vehicle and facilitating vehicle maintenance. The first bearing member is rotatably mounted on the shaft. When the first bearing member is subjected to pressure from the tire, the first bearing member can rotate around the shaft to change the relative position between the first bearing member and the second bearing member, thereby adapting to the tire model and improving the adaptability of the lifting fixture. When the first bearing member is under pressure and rotates around the shaft, the first limiting member rotates around the shaft and gradually approaches the tire. When the first limiting member and the first bearing member are both in contact with the tire, the tire can limit the rotation of the first bearing member relative to the shaft, allowing 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. There are at least three force points between the lifting fixture and the tire, which can improve the uniformity of the force applied to the tire and improve the stability of the lifted vehicle.

[0010] In some embodiments, the second bearing member is rotatably disposed on the shaft body, and the second bearing member further includes a second limiting portion connected to the second bearing portion. The second bearing member can be locked relative to the shaft body when the second limiting portion and the second bearing portion are both against the tire.

[0011] Both the first and second bearing members are rotatably mounted on the shaft, which increases the range of variation in the relative position between the first and second bearing members and improves adaptability. The second stopper further increases the number of points where the tire bears force, improving the uniformity of the force applied to the tire and enhancing the stability of the vehicle being lifted.

[0012] In some embodiments, when viewed in the vertical direction, the first bearing portion and the second bearing portion are respectively located on both sides of the axle to improve the uniformity of the force applied to the tire.

[0013] In some embodiments, when viewed vertically, the first limit portion is located on a side of the second bearing portion away from the shaft, and the second limit portion is located on a side of the first bearing portion away from the shaft. This embodiment of the present application can reduce the risk of interference between the first bearing member and the second bearing member during rotation.

[0014] In some embodiments, the first bearing portion and the second bearing portion are symmetrically arranged about the axis when viewed in the vertical direction, and the first limiting portion and the second limiting portion are symmetrically arranged about the axis. The embodiments of the present application can improve the uniformity of the force applied to the tire and improve the stability of the vehicle being lifted.

[0015] In some embodiments, the shaft extends along a first direction, and the first direction, second direction, and vertical direction are mutually perpendicular. When viewed from the second direction, the first stopper is located above the first support portion, and the second stopper is located above the second support portion. The first stopper and the second stopper can limit the tire from both sides in the second direction, thereby reducing the risk of the vehicle rolling away and, in turn, the risk of injury to maintenance personnel.

[0016] In some embodiments, the first supporting 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 supporting 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 two sides of the first rotating portion.

[0017] In some embodiments, the second support member 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 support member. The fourth connecting portion is connected to the second rotating portion, and the third and fourth connecting portions are respectively connected to opposite sides of the second rotating portion. The second limiting portion is connected to the fourth connecting portion, and the second support member can be locked relative to the shaft when both the second limiting portion and the second support member are in contact with the tire.

[0018] 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 space in the axial direction of the shaft, which can improve space utilization and increase the integration of the bearing assembly.

[0019] In some embodiments, the first support member further includes a third stopper connected to the first stopper. The third stopper is configured to limit movement of the tire in a first direction, which is parallel to the axial direction of the axle. The provision of the third stopper can reduce movement of the vehicle in the first direction, thereby reducing the risk of injury to maintenance personnel.

[0020] In some embodiments, the third limiting portion is adjustable in position on the first limiting portion in the first direction. The position of the third limiting portion can be adjusted according to the model of the tire, so that the lifting tool has better adaptability.

[0021] In some embodiments, the lifting tool includes two bearing assemblies, which are respectively arranged at both ends of the axle. The lifting tool can simultaneously carry two tires to improve the stability of the lifted vehicle.

[0022] In some embodiments, the axis of the shaft is parallel to the lateral direction of the vehicle and does not pass through the vehicle's door sill to reduce obstruction of the vehicle's bottom view and facilitate maintenance personnel's operation.

[0023] In some embodiments, the lifting fixture includes a connecting portion fixed to the shaft body, the connecting portion being used to connect to the lifting device. The lifting device can cooperate with the connecting portion to lift the vehicle by lifting the lifting fixture.

[0024] In a second aspect, embodiments of the present application provide a maintenance device comprising 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 support the vehicle's tires.

[0025] In a third aspect, an embodiment of the present application provides a battery swap station, comprising 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 support the vehicle's tires. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0043] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0045] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0046] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0047] The term "plurality" used in this application refers to two or more (including two).

[0048] In the embodiments of the present application, "parallel" includes not only the absolutely parallel situation, but also the roughly parallel situation conventionally recognized in engineering; at the same time, "vertical" includes not only the absolutely vertical situation, but also the roughly vertical situation conventionally recognized in engineering.

[0049] During the life cycle of a vehicle, the vehicle's battery may need to be replaced or repaired; and during the battery replacement or repair process, the vehicle usually needs to be lifted.

[0050] In the related art, the lifting device generally extends a lifting tray under the chassis of the vehicle and lifts the entire vehicle through the chassis; the lifting tray may block the battery, increasing the difficulty of battery replacement or maintenance.

[0051] In some embodiments, the present application provides a lifting fixture that can lift a vehicle's tires. For example, after a lifting device lifts the vehicle, the lifting fixture can be placed under the tires. The lifting device then places the vehicle on the lifting fixture. At this point, the lifting device's lifting tray no longer needs to support the vehicle's chassis; that is, the lifting tray can be detached from the vehicle's chassis, thereby reducing obstruction of the battery by the lifting tray.

[0052] However, the supporting member of the lifting fixture for bearing the weight of the vehicle is usually fixed, and the lifting fixture can only be adapted to a single type of tire.

[0053] In view of this, an embodiment of the present application provides a lifting fixture comprising an axle and a bearing assembly. The bearing assembly comprises a first bearing member and a second bearing member. The first bearing member is rotatably mounted on the axle, comprising a first bearing portion and a first stopper connected to the first bearing portion. The second bearing member is mounted on the axle and comprises a second bearing portion. The first bearing portion and the second bearing portion are used to support a vehicle tire. The first bearing member can be locked relative to the axle when both the first stopper and the first bearing portion are in contact with the tire.

[0054] The first bearing member is rotatably mounted on the shaft. When the first bearing member is subjected to pressure from the tire, the first bearing member can rotate about the shaft to change the relative position between the first bearing member and the second bearing member, thereby adapting to the tire model and improving the adaptability of the lifting fixture. When the first bearing member is under pressure and rotates about the shaft, the first limiting member rotates about the shaft and gradually approaches the tire. When the first limiting member and the first bearing member both abut against the tire, the tire can limit the rotation of the first bearing member relative to the shaft, allowing the first bearing member to stably support the tire. The first bearing member, the second bearing member, and the first limiting member all contact the tire, creating at least three force points between the lifting fixture and the tire. This improves the uniformity of force applied to the tire and enhances the stability of the lifted vehicle.

[0055] The lifting tool disclosed in the embodiment of the present application can be used as vehicle maintenance equipment, can be used in battery swap stations, and can also be applied to other scenarios that require lifting vehicles.

[0056] The lifting tooling, maintenance equipment and battery swap station of the present application are described in detail below with reference to the accompanying drawings.

[0057] Figure 1 is a schematic structural diagram of the lifting tool provided in some embodiments of the present application; Figure 2 is an enlarged schematic diagram of the circle frame in Figure 1; Figure 3 is a top view schematic diagram of the lifting tool shown in Figure 1; Figure 4 is a side view schematic diagram of the lifting tool shown in Figure 1; Figure 5 is a schematic diagram of the lifting tool shown in Figure 4 when lifting the tire of a vehicle.

[0058] 1 to 5 , the lifting tool 100 according to the embodiment of the present application includes a shaft body 1 and a bearing assembly 2 , and the bearing assembly 2 is disposed on the shaft body 1 .

[0059] Exemplarily, the load-bearing assembly 2 is used to abut against a tire 201 of a vehicle 200 and support the tire 201 .

[0060] There can be one or more bearing components 2. For example, there are multiple bearing components 2, and the multiple bearing components 2 are arranged along the axial direction of the shaft body 1.

[0061] In some embodiments, the supporting assembly 2 includes a first supporting member 21 and a second supporting member 22 . The first supporting member 21 is rotatably disposed on the shaft body 1 , and the second supporting member 22 is disposed on the shaft body 1 .

[0062] The bearing assembly 2 may include a first bearing member 21 or a plurality of first bearing members 21 ; the bearing assembly 2 may include a second bearing member 22 or a plurality of second bearing members 22 .

[0063] The first supporting member 21 may be directly connected to the shaft body 1 or indirectly connected to the shaft body 1 through other components.

[0064] The second supporting member 22 may be fixedly disposed on the shaft body 1 or rotatably disposed on the shaft body 1 .

[0065] In some embodiments, the first supporting member 21 includes a first supporting portion 211 , and the second supporting member 22 includes a second supporting portion 221 . The first supporting portion 211 and the second supporting portion 221 are used to support the tire 201 of the vehicle 200 .

[0066] Illustratively, the first carrier 21 may include one first carrier portion 211 , or may include a plurality of first carrier portions 211 .

[0067] For example, the first supporting portion 211 may include a rod-shaped structure, a spherical structure, or a structure of other shapes.

[0068] Illustratively, the second carrier 22 may include one second carrier portion 221 , or may include a plurality of second carrier portions 221 .

[0069] For example, the second supporting portion 221 may include a rod-shaped structure, a spherical structure, or a structure of other shapes.

[0070] For example, the first carrier 21 may be an integrally formed component, or a component formed by fixing a plurality of independent components together. The second carrier 22 may be an integrally formed component, or a component formed by fixing a plurality of independent components together.

[0071] In some embodiments, the first carrier 21 includes a first position-limiting portion 212 connected to the first carrier portion 211. For example, the first carrier 21 includes one first position-limiting portion 212 or a plurality of first position-limiting portions 212.

[0072] In some embodiments, the first supporting member 21 can be locked relative to the axle 1 when both the first limiting portion 212 and the first supporting portion 211 are in contact with the tire 201 .

[0073] For example, locking the first carrier 21 relative to the shaft body 1 may mean that “the rotation of the first carrier 21 relative to the shaft body 1 is locked”.

[0074] The first supporting member 21 is rotatably arranged on the shaft body 1. When the first supporting part 211 is subjected to pressure from the tire 201, the first supporting part 211 can rotate around the shaft body 1 to change the relative position between the first supporting part 211 and the second supporting part 221, thereby adapting to the model of the tire 201 and improving the adaptability of the lifting tooling 100. When the first bearing part 211 is compressed and rotates around the shaft 1, the first limiting part 212 rotates around the shaft 1 and gradually approaches the tire 201. When the first limiting part 212 and the first bearing part 211 are both against the tire 201, the tire 201 can limit the rotation of the first bearing member 21 relative to the shaft 1, so that the first bearing part 211 can 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, and there are at least three force points between the lifting tooling 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.

[0075] For example, the embodiment of the present application utilizes the mechanical structure of the first carrier 21 itself to achieve locking, without the need to add power structures such as cylinders and motors, thereby simplifying the structure of the lifting tool 100.

[0076] In some embodiments, the second support member 22 is rotatably disposed on the shaft body 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 body 1 when the second limiting portion 222 and the second support portion 221 are both against the tire 201.

[0077] Illustratively, the second supporting member 22 includes one second limiting portion 222 or a plurality of second limiting portions 222 .

[0078] For example, locking the second carrier 22 relative to the shaft body 1 may mean that “the rotation of the second carrier 22 relative to the shaft body 1 is locked”.

[0079] Both the first support member 21 and the second support member 22 are rotatably mounted on the shaft body 1. This increases the range of variation in the relative position between the first support member 211 and the second support member 221, improving adaptability. The provision of the second stopper 222 further increases the number of stress points on the tire 201, increasing the uniformity of stress applied to the tire 201 and improving the stability of the lifted vehicle 200.

[0080] In some embodiments, when observed along the vertical direction Z, the first bearing portion 211 and the first limiting portion 212 are respectively located on both sides of the shaft body 1. When one of the first bearing portion 211 and the first limiting portion 212 is subjected to pressure from the tire 201 and rotates, the other can move toward the tire 201 until it is in 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 applied to the first bearing portion 211 is opposite to the torque applied to the first limiting portion 212; when the torque applied to the first bearing portion 211 is balanced with the torque applied to the first limiting portion 212, the first bearing member 21 stops rotating.

[0081] As an example, the vertical direction Z is parallel to the direction of gravity.

[0082] In some embodiments, when observed along the vertical direction Z, the second bearing portion 221 and the second limiting portion 222 are respectively located on both sides of the shaft body 1. When one of the second bearing portion 221 and the second limiting portion 222 is subjected to pressure from the tire 201 and rotates, the other can move toward the tire 201 until it is in 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 applied to the second bearing portion 221 is opposite to the torque applied to the second limiting portion 222; when the torque applied to the second bearing portion 221 is balanced with the torque applied to the second limiting portion 222, the second bearing member 22 stops rotating.

[0083] In some embodiments, when viewed along the vertical direction Z, the first bearing portion 211 and the second bearing portion 221 are respectively located on two sides of the shaft body 1 to improve the uniformity of the force applied to the tire 201 .

[0084] In some embodiments, the first limiting portion 212 is located on a side of the second supporting portion 221 away from the shaft body 1 , and the second limiting portion 222 is located on a side of the first supporting portion 211 away from the shaft body 1 .

[0085] The embodiment of the present application can reduce the risk of interference between the first supporting member 21 and the second supporting member 22 during the rotation process.

[0086] In some embodiments, when viewed along the vertical direction Z, the first bearing portion 211 and the second bearing portion 221 are symmetrically arranged with respect to the shaft body 1 , and the first limiting portion 212 and the second limiting portion 222 are symmetrically arranged with respect to the shaft body 1 .

[0087] The embodiment of the present application can improve the uniformity of the force applied to the tire 201 and improve the stability of the lifted vehicle 200.

[0088] 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. Observed along the second direction X, the first limiting portion 212 is located above the first supporting portion 211 , and the second limiting portion 222 is located above the second supporting portion 221 .

[0089] The first limiting portion 212 and the second limiting portion 222 can limit the tire 201 from both sides of the second direction X, thereby reducing the risk of the vehicle 200 slipping and further reducing the risk of maintenance personnel being injured.

[0090] In some embodiments, the first supporting 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 supporting portion 211.

[0091] In some embodiments, the first rotating portion 213 includes a bearing.

[0092] In some embodiments, the first connecting portion 214 is a rod-shaped structure, and two ends of the first connecting portion 214 are respectively connected to the first rotating portion 213 and the first supporting portion 211 .

[0094] Optionally, there are multiple first connection portions 214 , and the multiple first connection portions 214 are arranged along the first direction Y. The multiple first connection portions 214 can improve the structural strength of the first supporting member 21 .

[0095] In some embodiments, there may be one or more second connection parts 215 .

[0096] In some embodiments, the first limiting portion 212 includes a first limiting rod extending along the first direction Y. The first limiting rod has a rod-shaped structure and has a large contact area with the tire 201 .

[0097] In some embodiments, there are multiple second connection portions 215 , and the multiple second connection portions 215 are arranged along the first direction Y. The multiple second connection portions 215 can improve the structural strength of the first supporting component 21 .

[0098] In some embodiments, the second connecting portion 215 includes a first rod 215a and a second rod 215b intersecting each other. The first rod 215a and the first connecting portion 214 are respectively connected to two 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.

[0099] By providing the intersecting first rod 215 a and second rod 215 b , the relative position of the first limiting portion 212 and the first supporting portion 211 can be adjusted, thereby facilitating the balance of the first supporting member 21 .

[0100] In some embodiments, the first rod 215a and the second rod 215b form a first preset angle, and optionally, the first preset angle is 60°-90°. Optionally, the first rod 215a and the second rod 215b are perpendicular.

[0101] In some embodiments, the first rod 215a and the second rod 215b are welded.

[0102] In some alternative embodiments, the second connecting portion 215 includes an arc-shaped rod, which can replace the first rod 215a and the second rod 215b that are arranged to intersect.

[0110] In some embodiments, there are multiple fourth connection portions 225 , and the multiple fourth connection portions 225 are arranged along the first direction Y. The multiple fourth connection portions 225 can improve the structural strength of the second supporting component 22 .

[0111] In some embodiments, the fourth connecting portion 225 includes a third rod 225a and a fourth rod 225b intersecting each other. The third rod 225a and the third connecting portion 224 are respectively connected to two sides of the second rotating portion 223. The third rod 225a connects the fourth rod 225b and the second rotating portion 223, and the second limiting portion 222 is connected to the fourth rod 225b.

[0112] By providing the intersecting third rod 225 a and fourth rod 225 b , the relative position of the second limiting portion 222 and the second supporting portion 221 can be adjusted, thereby facilitating the balance of the second supporting member 22 .

[0113] In some embodiments, the third rod 225a and the fourth rod 225b form a second predetermined angle therebetween. Optionally, the second predetermined angle is between 60° and 90°. Optionally, the third rod 225a and the fourth rod 225b are perpendicular. Optionally, the second predetermined angle is equal to the first predetermined angle.

[0114] In some embodiments, the third rod 225a and the fourth rod 225b are welded.

[0115] In some alternative embodiments, the fourth connecting portion 225 includes an arc-shaped rod, which can replace the intersecting third rod 225a and fourth rod 225b.

[0116] In some embodiments, when viewed along the vertical direction Z, the third connection portion 224 and the second connection portion 215 do not overlap, and the first connection portion 214 and the fourth connection portion 225 do not overlap.

[0117] In some embodiments, the second rotating portion 223 is sleeved on the shaft body 1, and the first rotating portion 213 is sleeved on the second rotating portion 223. The first rotating portion 213 and the second rotating portion 223 share a space in the axial direction of the shaft body 1, which can improve space utilization and increase the integration of the bearing assembly 2.

[0118] In some embodiments, the first bearing member 21 further includes a third limiting portion 216 connected to the first limiting portion 212. The third limiting portion 216 is used to limit the movement of the tire 201 in the first direction Y, which is parallel to the axial direction of the shaft 1.

[0119] As an example, when the first limiting portion 212 and the first bearing portion 211 both abut against the tire 201 , the third limiting portion 216 overlaps with the tire 201 in the first direction Y.

[0120] By providing the third limiting portion 216 , the movement of the vehicle 200 in the first direction Y can be reduced, thereby reducing the risk of injury to maintenance personnel.

[0121] 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.

[0122] In some embodiments, the second supporting member 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.

[0123] In some embodiments, the third limiting portion 216 is disposed on the first limiting portion 212 in an adjustable manner in the first direction Y.

[0124] The position of the third limiting portion 216 can be adjusted according to the model of the tire 201, so that the lifting tool 100 has better adaptability.

[0125] As an example, the third limiting portion 216 may be provided with a locking structure, and the locking structure is used to lock with the first limiting portion 212. For example, the locking structure includes a fastener.

[0126] When the position of the third limiting portion 216 needs to be adjusted, the lock between the locking structure and the first limiting portion 212 is released, and then the third limiting portion 216 is moved along the first direction Y. When the third limiting portion 216 moves to the target position, the locking structure is locked to the first limiting portion 212, thereby fixing the first limiting portion 212 and the third limiting portion 216.

[0127] In some embodiments, the lifting device 100 includes two bearing assemblies 2, which are respectively disposed at both ends of the axle 1. The lifting device 100 can simultaneously carry two tires 201 to improve the stability of the lifted vehicle 200.

[0128] In some embodiments, the axial direction of the shaft body 1 is parallel to the transverse direction of the vehicle 200. The shaft body 1 does not pass through the door sill of the vehicle 200 to reduce the obstruction of the bottom view of the vehicle 200 and facilitate the operation of maintenance personnel.

[0129] In some embodiments, the lifting tool 100 includes a connecting portion 3 fixed to the shaft body 1, and the connecting portion 3 is used to connect to a lifting device. The lifting device can cooperate with the connecting portion 3 to lift the vehicle 200 by lifting the lifting tool 100.

[0130] In some embodiments, the underside of the adapter 3 has a flat surface. The lifting tray of the lifting device can be moved to the underside of the adapter 3, forming a flat contact between the lifting tray and the adapter 3. This flat contact increases friction between the lifting tray and the adapter 3, reducing slippage of the adapter 3 on the lifting tray.

[0131] In some embodiments, there are two adapter parts 3 , and the two adapter parts 3 are respectively connected to the two ends of the shaft body 1 .

[0132] Figure 6 is a schematic diagram of the maintenance equipment provided in some embodiments of the present application; Figure 7 is another schematic diagram of the maintenance equipment provided in some embodiments of the present application; Figure 8 is yet another schematic diagram of the maintenance equipment provided in some embodiments of the present application.

[0133] 5 to 8 , an embodiment of the present application provides a maintenance device comprising a lifting device 300 and a lifting fixture 100 provided in any of the aforementioned embodiments. The lifting device 300 is used to lift a vehicle 200. The lifting fixture 100 is positioned under the vehicle 200 and supports the tire 201 of the vehicle 200.

[0134] In some embodiments, there are two lifting fixtures 100. The two bearing assemblies 2 of one lifting fixture 100 are used to support the two front tires, and the two bearing assemblies 2 of the other lifting fixture 100 are used to support the two rear tires.

[0135] For example, referring to FIG6 , when the battery of the vehicle 200 needs to be replaced or repaired, the lifting tray 301 of the lifting device 300 moves to the lower side of the vehicle 200 , and the lifting tray 301 lifts the sill beam or battery of the vehicle 200 , thereby lifting the vehicle 200 to a certain height.

[0136] Then, the two bearing assemblies 2 of one lifting fixture 100 are placed under the two front tires of the vehicle 200 respectively, and the two bearing assemblies 2 of the other lifting fixture 100 are placed under the two rear tires of the vehicle 200 respectively.

[0137] 5 and 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 supporting portion 211 and the second supporting portion 221, thereby pressing down the first supporting portion 211 and the second supporting portion 221.

[0138] Driven by the tire 201, the first and second bearing members 21 and 22 rotate, and the first and second limiting portions 212 and 222 rotate and press against the tire 201, thereby locking the tire 201 in the front-to-back direction of the vehicle. The third limiting portion 216 can limit the position of the tire 201 in the lateral direction of the vehicle 200.

[0139] The first bearing member 21 and the second bearing member 22 are rotatably disposed on the shaft 1 . The first bearing portion 211 , the second bearing portion 221 , the first limiting portion 212 and the second limiting portion 222 can adapt to different types of tires 201 by rotating around the shaft 1 .

[0140] The lifting tool 100 has lifted the vehicle 200, and the lifting tray 301 can continue to descend and detach from the vehicle 200. The lifting tray 301 no longer blocks the battery, making it easy to replace or repair the battery.

[0141] 8 , if the height of the vehicle 200 is insufficient, the lifting tray 301 can be moved to the lower side of the adapter 3. The lifting tray 301 rises and lifts the adapter 3, thereby lifting the vehicle 200 through the lifting tool 100 until the height of the vehicle 200 meets the maintenance requirements.

[0142] The adapter part 3 is connected to the end of the axle body 1, that is, the adapter part 3 is located on the outside of the tire 201; when the adapter part 3 is lifted, the lifting tray 301 and the vehicle 200 have a smaller overlap in the vertical direction Z, and the lifting tray 301 has less obstruction on the battery.

[0143] Compared with the solution of directly using the lifting tray 301 to lift the door sill beam, the embodiment of the present application uses two lifting tools 100 to lift the front tires and the rear tires respectively, thereby freeing up the space under the vehicle and making the operation more convenient.

[0144] The present application also provides a battery swap station, comprising a lifting device 300 and a lifting fixture 100 provided in any of the aforementioned embodiments. The lifting device 300 is used to lift a vehicle 200. The lifting fixture 100 is used to be positioned under the vehicle 200 and support the tire 201 of the vehicle 200.

[0145] For example, the battery swap station can use the same method as the maintenance equipment to lift the vehicle 200. When the vehicle 200 is lifted to a set height, the battery is removed and a new fully charged battery is installed.

[0146] 1 to 8 , an embodiment of the present application provides a lifting tool 100 , which includes a shaft 1 , two bearing assemblies 2 and two adapters 3 .

[0147] The shaft body 1 extends along a first direction Y, and the two adapter portions 3 are connected to two ends of the shaft body 1 along the first direction Y respectively.

[0148] The two supporting components 2 are disposed on the shaft body 1 , and the two supporting components 2 are spaced apart along the first direction Y.

The second connecting portion 215 connects the first rotating portion 213 and the first limiting portion 212. The first connecting portion 214 and the second connecting portion 215 are respectively connected to two sides of the first rotating portion 213.

[0151] The second rotating portion 223 is rotatably connected to the shaft body 1. The third connecting portion 224 connects the second rotating portion 223 and the second bearing portion 221. The fourth connecting portion 225 is connected to the second rotating portion 223 and the second limiting portion 222. The third connecting portion 224 and the fourth connecting portion 225 are respectively connected to two sides of the second rotating portion 223.

[0152] Observed along the vertical direction Z, the first bearing portion 211 and the second bearing portion 221 are respectively located on both sides of the shaft body 1. The first limiting portion 212 is located on the side of the second bearing portion 221 away from the shaft body 1, and the second limiting portion 222 is located on the side of the first bearing portion 211 away from the shaft body 1.

Observed along the second direction X, the first limiting portion 212 is located above the first supporting portion 211 , and the second limiting portion 222 is located above the second supporting portion 221 .

[0154] For example, the first bearing member 21 can be locked relative to the axle body 1 when both the first limiting portion 212 and the first bearing portion 211 abut against the tire 201. The second bearing member 22 can be locked relative to the axle body 1 when both the second limiting portion 222 and the second bearing portion 221 abut against the tire 201.

[0155] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts.
