Description

Technical Field

[0001] This application relates to the technical field of batteries, and particularly to a battery swapping station. Background Art

[0002] Energy conservation and emission reduction are the keys to the sustainable development of the automotive industry. In this context, electric vehicles have become an important component of the sustainable development of the automotive industry due to their advantages of energy conservation and environmental protection. For electric vehicles, battery technology is an important factor related to their development.

[0003] When the battery runs out of power, the battery is usually placed in a battery swapping station, and the battery is charged through the power connection mechanism in the battery swapping station. In the related art, the position accuracy of the battery in the battery swapping station is relatively low, and the power connection mechanism is easily damaged. Summary of the Utility Model

[0004] In view of the above problems, this application provides a battery swapping station to improve the position accuracy of the battery in the battery swapping station.

[0005] This application provides a battery swapping station, which includes a bracket, a power connection mechanism, and a limiting mechanism. The bracket forms a receiving space for accommodating a battery device. The power connection mechanism is fixedly arranged on the bracket and is used for electrically connecting with the battery device. The limiting mechanism is arranged on the bracket and is used for limiting the position of the battery device in the receiving space.

[0006] In the battery swapping station according to the embodiment of this application, the power connection mechanism is fixedly arranged on the bracket, which can reduce the movement of the power connection mechanism and improve the stability of the power connection mechanism. By limiting the battery device through the limiting mechanism, the position accuracy of the battery device in the receiving space can be improved, which is conducive to improving the connection accuracy between the battery device and the power connection mechanism, and reducing the risk of damaging the power connection mechanism due to collision between the battery device and the power connection mechanism.

[0007] In some embodiments, the bracket includes a support member, a fixing member, and a connecting member. The fixing member is arranged on the support member and extends along a first direction. The connecting member connects the ends of the support member and the fixing member and extends along a second direction. The first direction and the second direction intersect. The support member, the fixing member, and the connecting member jointly define and form the receiving space. The limiting mechanism is arranged on the support member, and the power connection mechanism is fixedly arranged on the fixing member.

[0008] In the above embodiment, the bracket is jointly formed by the support member, the fixing member, and the connecting member, so that the power connection mechanism and the battery device can be respectively arranged on different components, which is beneficial to reducing the interference between the power connection mechanism and the battery device.

[0009] In some embodiments, the limiting mechanism includes a slider and a mounting seat. The mounting seat is fixedly arranged on the bracket. The slider is slidably arranged on the mounting seat, and the slider is used for clamping with the battery device when sliding into the interior of the receiving space.

[0010] In the above embodiments, when the battery device moves closer to the slider in the vertical direction, the slider slides closer to the battery device in the first direction to achieve clamping with the battery device, which can reduce the clamping time between the battery device and the slider and thus improve the battery swapping efficiency.

[0011] In some embodiments, the mounting seat is formed with a chute that extends in the first direction, and the slider slides in the chute.

[0012] In the above embodiments, the chute can provide a sliding space for the slider and at the same time reduce the interference of the slider on the battery device.

[0013] In some embodiments, the mounting seat includes two mounting members that are oppositely arranged on the bracket, and a chute is formed between the two mounting members.

[0014] In the above embodiments, the slider is arranged between the two mounting members, which can limit the movement stroke of the slider in the direction of its own thickness and is beneficial to improving the clamping accuracy between the slider and the battery device.

[0015] In some embodiments, the mounting member is formed with a limiting hole that extends in the first direction, and the slider is formed with a protrusion that can slide in the limiting hole as the slider slides to limit the movement stroke of the slider.

[0016] In the above embodiments, by limiting the movement stroke of the protrusion through the limiting hole, the movement stroke of the slider is limited, which can reduce the risk that the slider moves too much into the accommodation space and collides with the battery device, causing damage to the battery device.

[0017] In some embodiments, the limiting mechanism includes a driving component and a push plate. The push plate is fixed on the slider, the driving component is connected to the push plate, and the driving component drives the slider to slide through the push plate.

[0018] In the above embodiments, the driving component drives the push plate to move, thereby driving the slider to move to achieve clamping between the slider and the battery device.

[0019] In some embodiments, the driving component includes a driving member and a transmission member. The transmission member connects the driving member and the push plate, and the driving member drives the slider to move through the transmission member.

[0020] In the above embodiments, the driving member can provide power, and the transmission member can transmit the power to the push plate to drive the push plate to move, thereby driving the slider to move.

[0021] In some embodiments, the driving assembly includes a first locking member and a second locking member. The transmission member forms a threaded hole that penetrates the transmission member along the radial direction of the transmission member. The first locking member passes through the threaded hole and one end thereof is screwed into the push plate. The second locking member is inserted at one end of the first locking member facing away from the push plate, and there is a gap between the second locking member and the transmission member.

[0022] In the above embodiment, the second locking member can limit the transmission member. There is a gap between the second locking member and the transmission member, so that when the battery device is clamped on the slider, under the gravity of the battery device, the push plate has room for up and down movement, reducing the risk of the slider being pressed down due to the downward pressure of the battery device, thereby causing damage to the transmission member.

[0023] In some embodiments, the slider forms a limiting groove that penetrates the slider along the thickness direction of the slider. The battery device is provided with a clamping member, and the battery device can be clamped in the limiting groove through the clamping member. When the clamping member is clamped in the limiting groove, the power connection mechanism is connected to the battery device.

[0024] In the above embodiment, by clamping the clamping member in the limiting groove, the relative position between the battery device and the bracket can be restricted, thereby improving the positioning accuracy of the battery device.

[0025] In some embodiments, the limiting groove includes a first limiting groove and a second limiting groove. The slider includes a first surface and a second surface that are arranged opposite to each other along the thickness direction of the slider. The first limiting groove extends from the first surface to the second surface, and the second limiting groove extends from the second surface to the first surface. The second limiting groove communicates with the first limiting groove. The cross-sectional area of the first limiting groove is larger than that of the second limiting groove. The clamping member passes through the second limiting groove and abuts against the surface of the first limiting groove that communicates with the second limiting groove.

[0026] In the above embodiment, the clamping member passes through the second limiting groove and abuts against the surface of the first limiting groove that communicates with the second limiting groove. This can reduce the rising height of the battery device, shorten the movement stroke and movement time of the battery device, which is beneficial to improving the battery swapping efficiency. At the same time, through the position of the clamping member in the first limiting groove, it is convenient to adjust the position of the slider, which is beneficial to improving the clamping stability of the battery device.

[0027] In some embodiments, the bracket forms a positioning hole, and the battery device is provided with a positioning member, and the positioning member is inserted into the positioning hole.

[0028] In the above embodiment, the positioning member is inserted into the positioning hole, which can limit the relative position between the battery device and the bracket, improve the positioning accuracy of the battery device and the bracket, and thus is beneficial to improving the docking accuracy between the battery device and the power connection mechanism.

[0029] In some embodiments, the bracket is provided with a limiting member for limiting the height of the battery device.

[0030] In the above embodiments, the limiting member can limit the rising height of the battery device, reduce the risk of the battery device damaging the power connection mechanism due to excessive upward movement stroke, and is beneficial to improving the safety of the power connection mechanism.

[0047] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydraulic, thermal, wind, and solar power stations, but also widely used in electric transportation means such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as aerospace. With the continuous expansion of the application fields of power batteries, the market demand for them is also continuously increasing.

[0048] In the present application, a battery refers to a physical module including one or more battery cells to provide electric energy. For example, the batteries mentioned in the present application can include battery modules or battery packs, etc. A battery generally includes a box for encapsulating one or more battery cells. The box can prevent liquids or other foreign objects from affecting the charging or discharging of the battery cells.

[0049] Optionally, the battery cell may include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery, a magnesium-ion battery, etc., and the embodiments of the present application are not limited thereto. The battery cell may be in a cylindrical shape, a flat shape, a cuboid shape or other shapes, etc., and the embodiments of the present application are not limited thereto either. Generally, the battery cells are divided into three types according to the encapsulation method: cylindrical battery cells, square battery cells and soft-pack battery cells, and the embodiments of the present application are not limited thereto either.

[0050] To meet different power requirements, the battery may include a plurality of battery cells. Among them, the plurality of battery cells may be connected in series, in parallel or in a series-parallel combination. The series-parallel combination means a combination of series and parallel connections. Optionally, the plurality of battery cells may first be connected in series, in parallel or in a series-parallel combination to form a battery module, and then a plurality of battery modules may be connected in series, in parallel or in a series-parallel combination to form a battery. That is to say, the plurality of battery cells may directly form a battery, or may first form a battery module, and then the battery module forms a battery. The battery is further arranged in a vehicle to provide electrical energy for the vehicle.

[0051] When the battery runs out of power, it is necessary to replenish the power of the battery. Since it takes a long time to replenish the power of the battery by charging. Therefore, by directly replacing the battery of the electrical device and using a fully charged battery to replace the depleted battery, the efficiency of replenishing the power of the electrical device can be effectively improved. Therefore, battery swapping stations have emerged and are becoming more and more popular in life. A battery swapping station is an energy station that provides charging and rapid battery replacement for the power battery of an electric vehicle. The battery swapping station charges the battery through a power connection mechanism. In the related art, the position accuracy of the battery in the battery swapping station is relatively low, and the power connection mechanism is easily damaged. To solve the above problems, the present application provides the following technical solutions.

[0052] Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 are schematic structural diagrams of a battery swapping station 100 according to some embodiments of the present application. The battery swapping station 100 according to the embodiment of the present application includes a bracket 10, a power connection mechanism 20 and a limiting mechanism 30. The bracket 10 is formed with an accommodation space 11 for accommodating the battery device 200. The power connection mechanism 20 is fixedly arranged on the bracket 10 and is used for electrically connecting with the battery device 200. The limiting mechanism 30 is arranged on the bracket 10 and is used for limiting the position of the battery device 200 in the accommodation space 11.

[0053] Specifically, the bracket 10 may be a frame structure, and the bracket 10 may provide support for the power connection mechanism 20 and the battery device 200. The shape and size of the accommodation space 11 may be adapted to the shape and size of the battery device 200. Exemplarily, if the battery device 200 is square, the accommodation space 11 is also square.

[0054] One or more batteries 210 can be carried on a battery device 200, that is, one or more batteries 210 can be charged simultaneously. Exemplarily, 2 batteries 210 are carried on the battery device 200, and the 2 batteries 210 are respectively located on both sides of the battery device 200. When the power connection mechanism 20 is electrically connected to the battery device 200, the 2 batteries 210 are charged.

[0055] The power connection mechanism 20 can be a station-side water and electricity connector. The power connection mechanism 20 is used to connect an external power source and the battery device 200 to charge the battery 210 through the battery device 200.

[0056] The number of the limiting mechanisms 30 can be multiple. In one embodiment, the number of the limiting mechanisms 30 is 4, and the 4 limiting mechanisms 30 are arranged at intervals to limit 4 parts of the battery device 200.

[0057] In the above embodiment, the power connection mechanism 20 is fixedly arranged on the bracket 10, which can reduce the movement of the power connection mechanism 20 and improve the stability of the power connection mechanism 20. Limiting the battery device 200 through the limiting mechanism 30 can improve the position accuracy of the battery device 200 in the accommodation space 11, thereby facilitating the improvement of the connection accuracy between the battery device 200 and the power connection mechanism 20 and reducing the risk of damaging the power connection mechanism 20 due to collision between the battery device 200 and the power connection mechanism 20.

[0058] Please refer to Figure 2 , in some embodiments, the bracket 10 includes a support member 12, a fixing member 13 and a connecting member 14. The fixing member 13 is arranged on the support member 12 and extends along the first direction D1. The connecting member 14 connects the ends of the support member 12 and the fixing member 13 and extends along the second direction D2. The first direction D1 and the second direction D2 intersect. The support member 12, the fixing member 13 and the connecting member 14 jointly define and form the accommodation space 11. The limiting mechanism 30 is arranged on the support member 12, and the power connection mechanism 20 is fixedly arranged on the fixing member 13.

[0059] Specifically, the support member 12 can extend along the vertical direction. The fixing member 13 is arranged at the upper end of the support member 12, and the power connection mechanism 20 is fixed on one side of the fixing member 13 facing the lower end of the support member 12. The first direction D1 can be the width direction of the bracket 10, and the second direction D2 can be the length direction of the bracket 10. The support member 12, the fixing member 13 and the connecting member 14 can be fixedly connected by welding, bonding and other means.

[0060] In one embodiment, the number of the support members 12 is 10. The 10 support members 12 are divided into two columns. The two columns of support members 12 are arranged at intervals along the first direction D1. Each column of 5 support members 12 is arranged at intervals along the second direction D2. The two columns of support members 12 correspond to each other one by one. The number of the connecting members 14 is 4. The 4 connecting members 14 respectively connect the two ends of the two columns of support members 12. The number of the fixing members 13 is 6. The two ends of the 6 fixing members 13 respectively connect the two connecting members 14 located at the upper part of the bracket 10 and are arranged at intervals along the second direction D2. The power connection mechanism 20 is fixed on the middle two fixing members 13. The lengths of each support member 12 can be the same or different. The connecting member 14 connects the end of the support member 12. It can be that the connecting member 14 abuts against the end face of the support member 12, or the connecting member 14 abuts against the side face of the support member 12 close to the end.

[0061] In the above embodiment, the bracket 10 is formed by the support member 12, the fixing member 13 and the connecting member 14 together, so that the power connection mechanism 20 and the battery device 200 can be respectively arranged on different components, which is beneficial to reducing the interference between the power connection mechanism 20 and the battery device 200.

[0062] Please refer to Figure 3 , Figure 3 which is a partial structural schematic diagram of the power exchange station 100 according to some embodiments of the present application. In some embodiments, the limiting mechanism 30 includes a slider 31 and a mounting seat 32. The mounting seat 32 is fixedly arranged on the bracket 10. The slider 31 is slidably arranged on the mounting seat 32. The slider 31 is used for being clamped with the battery device 200 when sliding towards the inside of the accommodating space 11.

[0063] Specifically, the slider 31 can be a square plate-like structure. The number of the mounting seats 32 can be 2. The 2 mounting seats 32 are respectively fixed on the mutually close surfaces of two adjacent support members 12 arranged along the second direction D2. The slider 31 slides between the 2 mounting seats 32 close to or away from the accommodating space 11.

[0064] In one embodiment, the number of the limiting mechanisms 30 is 4, the number of the sliders 31 is 4, the number of the mounting seats 32 is 8, and both ends of the slider 31 are respectively arranged in 2 mounting seats 32. The 4 limiting mechanisms 30 are evenly distributed at the four corners of the bracket 10, and can evenly bear the weight of the battery device 200, which is beneficial to improving the stability of the battery device 200.

[0065] In the above embodiment, when the battery device 200 moves close to the slider 31 in the vertical direction, the slider 31 slides close to the battery device 200 along the first direction D1 to realize the clamping with the battery device 200, which can reduce the clamping time between the battery device 200 and the slider 31, thereby improving the power exchange efficiency.

[0066] Please refer toFigure 3 In some embodiments, the mounting base 32 is formed with a sliding groove 321 that extends along the first direction D1, and the slider 31 slides in the sliding groove 321.

[0067] Specifically, two mounting bases 32 form two sliding grooves 321. The two ends of the slider 31 are respectively inserted into the two sliding grooves 321, and the slider 31 moves along the first direction D1 in the sliding groove 321 to approach or move away from the accommodation space 11.

[0068] In the above embodiment, the sliding groove 321 can provide a sliding space for the slider 31 and at the same time reduce the interference of the slider 31 on the battery device 200.

[0069] Please refer to Figure 3 In some embodiments, the mounting base 32 includes two mounting members 33. The two mounting members 33 are oppositely arranged on the bracket 10, and a sliding groove 321 is formed between the two mounting members 33.

[0070] Specifically, the mounting member 33 may include a first mounting portion 331 and a second mounting portion 332. The first mounting portion 331 and the second mounting portion 332 form an L shape and are integrally formed. The first mounting portion 331 is fixed to the support member 12 by welding or fasteners such as bolts. The two mounting members 33 are arranged at intervals in the vertical direction, and the sliding groove 321 is the gap formed between the second mounting portions 332 of the two mounting members 33.

[0071] In the above embodiment, the slider 31 is arranged between the two mounting members 33, which can limit the movement stroke of the slider 31 in the direction of its own thickness, and is beneficial to improving the clamping accuracy of the slider 31 and the battery device 200.

[0072] Please refer to Figure 3 and Figure 4 , Figure 4 FIGS.

[26] and

[27] are partial structural schematic diagrams of the battery swapping station 100 according to some embodiments of the present application. In some embodiments, the mounting member 33 is formed with a limiting hole 333 that extends along the first direction D1. The slider 31 is formed with a protrusion 311, and the protrusion 311 can slide in the limiting hole 333 as the slider 31 slides to limit the movement stroke of the slider 31.

[0073] Specifically, the limiting hole 333 may penetrate the mounting member 33 along the thickness direction of the mounting member 33. Further, the limiting hole 333 may penetrate the second mounting portion 332 along the thickness direction of the second mounting portion 332. The protrusion 311 may be integrally formed with the slider 31, and the protrusion 311 may protrude from the limiting hole 333, which can reduce the risk of the slider 31 detaching from the mounting member 33.

[0074] The limiting holes 333 may be formed on both of the two mounting members 33 of the mounting base 32, or may be formed on one of the mounting members 33. Similarly, the protrusion 311 may be formed on one side of the slider 31 in the thickness direction, or may be formed on both sides of the slider 31 in the thickness direction.

[0075] One limiting hole 333 may be formed on the mounting member 33, or two or more limiting holes 333 may be formed. Similarly, one protrusion 311 may be formed on one side of the slider 31 in the thickness direction, or two or more protrusions 311 may be formed. The multiple protrusions 311 and the multiple limiting holes 333 are arranged in one-to-one correspondence.

[0076] In the above embodiment, the movement stroke of the protrusion 311 is restricted by the limiting hole 333, so as to restrict the movement stroke of the slider 31, which can reduce the risk that the slider 31 moves too much into the accommodation space 11 and collides with the battery device 200, resulting in damage to the battery device 200.

[0077] Please refer to Figure 3 and Figure 4 , in some embodiments, the limiting mechanism 30 includes a driving component 34 and a pushing plate 35. The pushing plate 35 is fixed on the slider 31, the driving component 34 is connected to the pushing plate 35, and the driving component 34 drives the slider 31 to slide through the pushing plate 35.

[0078] The pushing plate 35 may be L-shaped and fixed on the slider 31 by means of welding, bonding, etc. The pushing plate 35 may also be flat and integrally formed with the slider 31. Exemplarily, the pushing plate 35 is formed by extending one side of the slider 31 in the thickness direction.

[0079] In the above embodiment, the driving component 34 drives the pushing plate 35 to move, thereby driving the slider 31 to move, so as to realize the clamping connection between the slider 31 and the battery device 200.

[0080] Please refer to Figure 3 and Figure 5 , Figure 5 is a schematic structural diagram of the power exchange station 100 according to some embodiments of the present application. In some embodiments, the driving component 34 includes a driving member 36 and a transmission member 37. The transmission member 37 connects the driving member 36 and the pushing plate 35, and the driving member 36 drives the slider 31 to move through the transmission member 37.

[0081] Specifically, the driving member 36 may be a motor, and the transmission member 37 may be a screw rod. The transmission member 37 extends along the first direction D1. When the motor is working, the push plate 35 is driven to move through the screw rod, thereby driving the slider 31 to move. The driving member 36 may be fixed to the bracket 10. For example, the driving member 36 is fixed to the connecting member 14, or is fixed to the supporting member 12 through a connecting rod. The driving member 36 may be located above the slider 31, or may be located below the slider 31.

[0082] In the above embodiment, the driving member 36 can provide power, and the transmission member 37 can transmit the power to the push plate 35 to drive the push plate 35 to move, thereby driving the slider 31 to move.

[0083] Please refer to Figure 3 and Figure 5 In some embodiments, the drive assembly 34 includes a first locking member 38 and a second locking member 39. The transmission member 37 forms a threaded hole 371, and the threaded hole 371 penetrates the transmission member 37 in the radial direction of the transmission member 37. The first locking member 38 passes through the threaded hole 371 and one end is screwed into the push plate 35. The second locking member 39 is inserted into the end of the first locking member 38 away from the push plate 35, and there is a gap between the second locking member 39 and the transmission member 37.

[0084] Specifically, the first locking member 38 can be a bolt, the second locking member 39 can be a nut, and the surface of the push plate 35 facing the transmission member 37 can extend inward to form a threaded groove. The first locking member 38 is connected to the second locking member 39, the transmission member 37 and the push plate 35 through threads, which can reduce the looseness of the connection caused by the gravity of the battery device 200, which is beneficial to improve the connection stability, and is easy to disassemble and assemble, making it convenient to repair and replace the drive assembly 34.

[0085] In the above embodiment, the second locking member 39 can limit the transmission member 37. There is a gap between the second locking member 39 and the transmission member 37, so that when the battery device 200 is clamped on the slider 31, under the action of the gravity of the battery device 200, the push plate 35 has space to move up and down, thereby reducing the risk of the battery device 200 pressing down and causing the slider 31 to press down, thereby causing damage to the transmission member 37.

[0086] Please refer to Figures 1 - 4 In some embodiments, the slider 31 forms a limiting groove 312, and the limiting groove 312 penetrates the slider 31 along the thickness direction of the slider 31. The battery device 200 is provided with a clamping member 220, and the battery device 200 can be clamped in the limiting groove 312 through the clamping member 220. When the clamping member 220 is clamped in the limiting groove 312, the power connection mechanism 20 is connected to the battery device 200.

[0087] Specifically, the limiting groove 312 can be a U-shaped groove, and the clamping member 220 can be a T-shaped structure. The limiting groove 312 communicates with the surface of the slider 31 close to the accommodating space 11, so that the clamping member 220 can enter the limiting groove 312 from the surface of the slider 31 close to the accommodating space 11.

[0088] The power connection mechanism 20 is connected to the battery device 200, which means that by controlling the power on and off of the power connection mechanism 20, the power on and off of the battery device 200 can be controlled. When the power connection mechanism 20 is powered on, the power connection mechanism 20 is electrically connected to the battery device 200, and the battery 210 is charged through the battery device 200. When the power connection mechanism 20 is powered off, the power connection mechanism 20 is disconnected from the battery device 200.

[0089] In the above embodiment, by clamping the clamping member 220 in the limiting groove 312, the relative position between the battery device 200 and the bracket 10 can be restricted, thereby improving the positioning accuracy of the battery device 200.

[0090] Please refer to Figures 2 - 4 , in some embodiments, the limiting groove 312 includes a first limiting groove 313 and a second limiting groove 314. The slider 31 includes a first surface 315 and a second surface 316 arranged opposite to each other along the thickness direction of the slider 31. The first limiting groove 313 extends from the first surface 315 to the second surface 316, and the second limiting groove 314 extends from the second surface 316 to the first surface 315. The second limiting groove 314 communicates with the first limiting groove 313. The cross-sectional area of the first limiting groove 313 is larger than that of the second limiting groove 314. The clamping member 220 passes through the second limiting groove 314 and abuts against the surface of the first limiting groove 313 communicating with the second limiting groove 314.

[0091] Specifically, the clamping member 220 includes a first clamping portion 221 and a second clamping portion 222. The second clamping portion 222 is inserted into the second limiting groove 314. The first clamping portion 221 is located in the first limiting groove 313. The cross-sectional area of the first clamping portion 221 is larger than that of the second clamping portion 222. The size of the cross-section of the second clamping portion 222 is less than or equal to the size of the cross-section of the second limiting groove 314. The size of the cross-section of the first clamping portion 221 is larger than the size of the cross-section of the second limiting groove 314 and less than the size of the cross-section of the first limiting groove 313. This can reduce the risk of damage to the limiting groove 312 and the clamping member 220 caused by the positional deviation between the slider 31 and the battery device 200.

[0092] In the above embodiment, the clamping member 220 passes through the second limiting groove 314 and abuts against the surface of the first limiting groove 313 communicating with the second limiting groove 314, which can reduce the rising height of the battery device 200, shorten the movement stroke and movement time of the battery device 200, and is beneficial to improving the battery swapping efficiency. At the same time, the position of the slider 31 can be adjusted conveniently through the position of the clamping member 220 in the first limiting groove 313, which is beneficial to improving the clamping stability of the battery device 200.

[0093] Please refer to Figure 1 , Figure 2 and Figure 5 , in some embodiments, the bracket 10 is formed with a positioning hole 15, and the battery device 200 is provided with a positioning member 230, and the positioning member 230 is inserted into the positioning hole 15.

[0094] Specifically, the support member 12 extends inwardly into the accommodation space 11 to form a positioning block 16, and the positioning hole 15 is formed on the positioning block 16. The positioning hole 15 penetrates the positioning block 16 along the thickness direction of the positioning block 16. The positioning hole 15 can be circular, and the positioning member 230 can be conical.

[0095] The number of the positioning holes 15 and the positioning members 230 can be multiple. In one embodiment, the number of both the positioning holes 15 and the positioning members 230 is 2. The two positioning members 230 and the two positioning holes 15 correspond to each other one by one, and the two positioning members 230 and the two positioning holes 15 are arranged at intervals along the first direction D1 and the second direction D2.

[0096] In the above embodiment, when the positioning member 230 is inserted into the positioning hole 15, the relative positions of the battery device 200 and the bracket 10 can be restricted, the positioning accuracy of the battery device 200 and the bracket 10 can be improved, and thus the docking accuracy between the battery device 200 and the power connection mechanism 20 can be improved.

[0097] Please refer to Figure 3 , in some embodiments, the bracket 10 is provided with a limiting member 17, and the limiting member 17 is used to limit the height of the battery device 200.

[0098] Specifically, the limiting member 17 can be fixed on the support member 12 by welding or fasteners such as bolts, and the limiting member 17 extends toward the accommodation space 11. The number of the limiting members 17 can be one or multiple. In one embodiment, the number of the limiting members 17 is 2, and the two limiting members 17 are respectively arranged on the mutually adjacent surfaces of the two support members 12 arranged at intervals along the first direction D1.

[0099] In the above embodiment, the limiting member 17 can limit the rising height of the battery device 200, reduce the risk that the upward movement stroke of the battery device 200 is too large and damages the power connection mechanism 20, and is beneficial to improving the safety of the power connection mechanism 20.

[0100] The working principle of the battery swapping station 100 according to the embodiments of the present application is as follows: The robotic arm is used to send the battery device 200 into the accommodation space 11. The robotic arm first drives the battery device 200 to move along the second direction D2 until the positioning member 230 is aligned with the positioning hole 15. Then the robotic arm drives the battery device 200 to move upward in the vertical direction. The positioning member 230 passes through the positioning hole 15 until the stroke ends. At the same time, the driving assembly 34 drives the slider 31 to move closer to the accommodation space 11. When the protrusion 311 slides to the end of the limit hole 333, at this time, the clamping member 220 on the battery device 200 passes through the limit groove 312 formed on the slider 31. The robotic arm releases the battery device 200, and the clamping member 220 abuts against the surface of the first limit groove 313 communicating with the second limit groove 314, fixing the battery device 200 on the bracket 10. At the same time, the battery device 200 is connected to the power connection mechanism 20. When the battery 210 needs to be charged, the power connection mechanism 20 is energized with the battery device 200, and the battery 210 is charged through the battery device 200. When the battery 210 is fully charged, the power connection mechanism 20 is de-energized from the battery device 200.
