Description

[0001] This application claims the priority of Chinese Patent Application No. 202410380046.4 with a filing date of March 29, 2024. This application incorporates the entire text of the above-mentioned patent application by reference. Technical Field

[0002] This application belongs to the technical field of electric vehicle battery swapping, and particularly relates to a battery swapping device. Background Art

[0003] With the development and popularization of new energy vehicles, the battery pack quick swapping technology has also developed rapidly. For large vehicles, such as heavy trucks or light trucks, the vehicle body and the cargo weight are very large, resulting in a high demand for the battery pack capacity of large vehicles. Only a sufficiently large-capacity electric energy can support the use of large vehicles.

[0004] In the traditional battery swapping mode, large vehicles in the new energy series all fix relatively large battery containers on the vehicle's beam through overhead lifting. The battery container is set adjacent to the driver's cab, which brings great safety hazards to the driver and the vehicle itself during driving and overhead battery swapping; moreover, if the battery fails, etc., it will directly cause personal injury to the driver. In addition, the overhead lifting method has high requirements for the site of the battery swapping station. The battery swapping station needs to have a sufficiently large area to execute the transfer of the lifting equipment for the battery and store the battery, etc., resulting in a high construction cost.

[0005] Therefore, for large vehicles, there is an urgent need for a safer, more reliable, and easier-to-popularize battery swapping mode. For example, adopting the chassis-type battery swapping mode of passenger cars. In the chassis-type battery swapping mode, it is necessary to control the entire battery swapping device to move to the battery swapping position under the battery swapping vehicle, and then perform the lifting operation and the operation of disassembling or installing the battery pack to complete the entire battery swapping process. During this battery swapping process, due to the limited space at the bottom of the battery swapping vehicle, especially for heavy truck battery swapping vehicles, etc., it is difficult to drive and park on a platform higher than the ground, making the space at the bottom of the battery swapping vehicle more restricted. If a battery swapping device is used for battery swapping, during the battery swapping process, the battery swapping device needs to carry the depleted battery pack or the fully charged battery pack to move back and forth and enter and exit the bottom of the battery swapping vehicle. To meet the power demand of heavy truck battery swapping vehicles, the battery packs are very large, which greatly limits the available space of the battery swapping device and the in-station battery storage device. At this time, if the available space of the battery swapping device is to be increased, the battery swapping device can only move in the space sunken from the ground. Due to the multiple trips of the heavy truck battery swapping vehicle before and after battery swapping, this will inevitably lead to an unreliable ground structure in this way, making it difficult to bear the multiple loads of the battery swapping vehicle, reducing the service life of the equipment structure, and also posing a safety hazard to the battery swapping vehicle.

[0006] In addition, due to the large body size and weight of heavy trucks, the range of adjustability of the body attitude of heavy trucks in a limited space is extremely small and difficult to adjust. At the same time, the body of heavy trucks usually tilts to a certain extent under loaded conditions or after long-term loaded use. Existing battery swapping mechanisms that can reach under the heavy truck for battery swapping operations usually can only maintain a horizontal state. This results in frequent situations during actual battery swapping where the battery swapping structure cannot precisely cooperate with the vehicle chassis to complete the disassembly and assembly of the battery pack due to the tilt of the heavy truck body, which is likely to cause damage to the battery pack, the vehicle body, and the battery swapping mechanism, and is also not conducive to improving the battery swapping efficiency.

[0007] Thus, it can be seen that there are many drawbacks in the existing technology that need to be further improved and enhanced. Summary of the Invention

[0008] The present application provides a battery swapping device. The tilt of the battery swapping main body can drive the deflection of the battery swapping device to adjust the horizontal angle of the battery swapping device, so that the battery swapping device can better adapt to the tilt of the vehicle chassis itself and / or the tilt of the vehicle chassis caused by factors such as vehicle load and uneven ground at the parking position. This ensures that the battery swapping device can fit well with the vehicle chassis when performing battery swapping operations, is conducive to accurately and quickly disassembling and assembling the depleted battery and the fully charged battery, and improves the battery swapping efficiency to solve at least one of the above technical problems.

The battery swapping device further includes a plurality of sliding mechanisms slidably disposed on the side walls of a plurality of columns of the support frame. The battery swapping main body is connected between the plurality of sliding mechanisms, and one end of the battery swapping main body is rotatably connected to the corresponding sliding mechanism, and the other end is movably connected to the corresponding sliding mechanism.

[0011] In the above solution, the inclination of the battery swapping main body can drive the deflection of the battery swapping device to adjust the horizontal angle of the battery swapping device, so that the battery swapping device can better adapt to the inclination of the vehicle chassis itself and / or the inclination of the vehicle chassis caused by factors such as vehicle load and uneven ground at the parking position, ensuring that the battery swapping device can fit well with the vehicle chassis during the battery swapping operation, which is beneficial to accurately and quickly disassembling and assembling the depleted battery and the fully charged battery, and improving the battery swapping efficiency; at the same time, one end of the battery swapping main body is rotatably connected to the sliding mechanism, and the other end is both rotatably connected to the sliding mechanism and can move relative to the sliding mechanism. While facilitating the adjustment of the inclination angle by making the heights of both ends of the battery swapping main body different, it is also convenient to eliminate the influence of the change in the horizontal distance between the battery swapping main body and the sliding mechanism when the battery swapping main body is inclined on the connection structure between the battery swapping main body and the sliding mechanism, thereby being beneficial to ensuring the stability of the connection structure between the battery swapping main body and the sliding mechanism.

[0012] As a preferred embodiment of the present application, a connecting shaft is provided on the end face of one of the battery swapping main body and the sliding mechanism, and a through hole or a waist-shaped hole is provided on the end face of the other, so as to realize the rotational connection or the movable connection between the battery swapping main body and the sliding mechanism.

[0013] In the above solution, the rotational connection between the battery swapping main body and the sliding mechanism can be realized through the cooperation between the connecting shaft and the through hole, and the rotational connection and the movable connection between the battery swapping main body and the sliding mechanism can be realized through the cooperation between the connecting shaft and the waist-shaped hole. The cooperation structure is simple, convenient for disassembly and assembly, and has a low maintenance cost, and the structures of the connecting shaft, the through hole and the waist-shaped hole are simple and easy to process. Setting the connecting shaft, the through hole and the waist-shaped hole will not cause the structural strength of the battery swapping main body and the sliding mechanism to be excessively reduced.

[0014] As a preferred embodiment of the present application, the support frame includes a plurality of columns respectively arranged on the periphery of the battery swapping main body.

[0015] A plurality of the sliding mechanisms are respectively arranged corresponding to two adjacent ones of the columns.

[0016] The battery swapping main body includes a box body provided with the battery swapping device and an installation part arranged on the top surface of the box body, and the installation part is connected between a plurality of the sliding mechanisms.

[0017] In the above solution, the setting of the columns can provide support for the sliding mechanism and the battery swapping body, and can directly provide guidance for the lifting movement of the sliding mechanism; the setting of the box body can provide support and protection for the battery swapping device, and can also provide protection for the battery pack during the process of the battery swapping device carrying and transporting depleted batteries or fully charged batteries, avoiding damage to the battery pack caused by collision and avoiding damage to the battery pack from falling off the battery swapping device; preferably, in the above solution, the box body is rotatably connected to the installation part, so as to facilitate the box body to drive the battery swapping device to adjust the orientation to better adapt to different vehicle models and / or vehicle parking positions.

[0018] As a preferred embodiment of the present application, the battery swapping device further includes two independent lifting drive mechanisms respectively arranged on both sides of the battery swapping body;

[0019] The battery swapping device further includes counterweights. The lifting drive mechanism includes a motor. A vertically movable counterweight is provided at each column. The counterweight is connected to the sliding mechanism on its corresponding side through a chain. A sprocket cooperating with the chain on its side is provided above each column. The motor drives the synchronous shaft to rotate, thereby simultaneously driving the two chains on the same side of the battery swapping body to drive the sliding mechanism to move vertically.

[0020] In the above solution, setting two independent lifting drive mechanisms to independently control the lifting height on both sides of the battery swapping body facilitates the battery swapping body to tilt to adapt to different vehicle chassis; at the same time, the motor has the advantages of fast response speed and easy control, which is convenient for accurately regulating the lifting height and tilt angle of the battery swapping device; the setting of the counterweight can provide a safety measure for the battery swapping device and the battery pack it carries, avoiding damage to the battery swapping device and the battery it carries directly falling due to motor failure.

[0021] As a preferred embodiment of the present application, the counterweight is located at the end side adjacent to the battery swapping body or on the other opposite side.

[0022] In the above solution, there are two setting positions for the counterweight. One is to set it at the end side adjacent to the battery swapping body, which is convenient for transporting the batteries between the battery compartments. The other is to set it on the other opposite side of the battery swapping body, optimizing the space utilization efficiency of the battery swapping station.

[0023] As a preferred embodiment of the present application, the number of the columns is four, and the installation part includes two cross beams respectively corresponding to the columns at both ends;

[0024] The sliding mechanism includes at least two sliders respectively attached to the side walls of the columns and a connecting rod connecting the sliders on both sides.

[0025] In the above solution, four columns are provided, which facilitates the grouped and independent installation of the sliding mechanism and the lifting drive mechanism. Moreover, with the above arrangement of the columns, sufficient supporting capacity can be provided while reducing the obstruction of the columns to the box body in the circumferential direction, facilitating the adjustment of the orientation of the box body; the setting of the connecting rod between the sliders can improve the structural strength of the sliding mechanism and also facilitate ensuring the synchronization of the lifting movements of the sliders at both ends of the connecting rod.

[0026] As a preferred embodiment of the present application, the connecting shafts are provided through the side walls near both ends of the cross beam, and a bushing is fixedly provided inside the cross beam for installing the connecting shafts; U-shaped lugs are provided on the side wall of the connecting rod facing the battery swapping main body, and through holes or waist-shaped holes are provided on the lug side walls of the U-shaped lugs.

[0027] In the above solution, the connecting shaft can be integrally formed with the cross beam, thereby enhancing the connection strength between the connecting shaft and the cross beam; by providing the bushing, it can play a protective role for the connecting shaft, and at the same time, it is also convenient to lubricate between the bushing and the connecting shaft, reducing the frictional loss of the connecting shaft.

[0028] As a preferred embodiment of the present application, U-shaped lugs are provided on the side walls near both ends of the connecting rod, the connecting shafts are provided through the U-shaped lugs, and connectors matching the distances between the two sliding mechanisms are respectively provided at both ends of the cross beam. Through holes or moving grooves are provided on the connectors. The through holes are circular holes that penetrate the connectors and match the connecting shafts, and the moving grooves are waist-shaped holes that extend along the length direction of the cross beam and penetrate the connectors.

[0029] With the above structure, the connector can be connected to the installation part after the connectors are connected. Compared with the previous solution where the connecting shaft is directly provided on the cross beam, it can more conveniently realize the cooperation between the connecting shaft and the through hole and the waist-shaped hole, which is beneficial to reducing the assembly difficulty.

[0030] As a preferred embodiment of the present application, the sliding mechanism includes a connecting rod and vertically arranged fixing plates fixed at both ends of the connecting rod. At least two sliders are sequentially provided on the side wall of each column and one of the fixing plates along the lifting movement direction, and a slide rail matching the sliders is provided on the side wall of the other.

[0031] In the above solution, the matching structure between the slider and the slide rail is simple, convenient to set, and beneficial to the limit of the lifting movement of the sliding mechanism; at the same time, at least two sliders are sequentially provided along the lifting movement direction, which can further limit the running track of the sliding mechanism, prevent deviation during the lifting process, and improve stability.

[0032] As a preferred embodiment of the present application, at least two rollers are provided on two adjacent vertical side walls of the fixing plate adjacent to the column, and rolling surfaces cooperating with the rollers are provided on two mutually perpendicular side walls of the column corresponding thereto.

[0033] In the above solution, through the arrangement of the rollers and the rolling surfaces and the cooperation between the two, the stability of the moving path when the sliding mechanism moves up and down relative to the column can be further ensured, which is beneficial to ensuring the adjustment accuracy of the height and the inclination angle of the battery swapping device.

[0034] As a preferred embodiment of the present application, the installation part further includes a plurality of longitudinal beams vertically and fixedly connected to the cross beam, as well as a first strengthening part and a second strengthening part.

[0035] The first strengthening part includes a plurality of strengthening plates connecting two adjacent longitudinal beams.

[0036] The second strengthening part includes a plurality of transition connecting plates, and the transition connecting plates are arranged on the beam surfaces at the connection parts of the strengthening plates and the longitudinal beams.

[0037] In the above solution, through the arrangement of the first strengthening part and the second strengthening part, the structural strength of the linkage part can be improved, thereby avoiding deformation or fracture of the linkage part due to the excessive weight of components such as the box body, the telescopic mechanism arranged inside the box body, and the battery pack carried, ensuring the safe and stable operation of the equipment; and the structure of the strengthening plate is simple and convenient to arrange, and adopting the above strengthening structure will not occupy too much installation space on the upper part of the installation plate. By arranging the strengthening plates, the planning and arrangement of the installation space on the upper part of the installation plate can be realized, which is convenient for the arrangement of additional components such as the foregoing motor, and at the same time can also provide partial protection for additional components such as the motor.

[0038] As a preferred embodiment of the present application, the transition connecting plate includes a first strengthening rib plate.

[0039] The first strengthening rib plate is arranged at the connection part of the connecting rod and the longitudinal beam, and is located on the two beam surfaces of the connecting rod and the longitudinal beam that are opposite up and down.

[0040] In the above solution, the first strengthening rib plate is located at the connection part of the cross beam and the longitudinal beam and is arranged on the two beam surfaces that are opposite up and down, which can provide additional structural support in the horizontal and vertical directions, enhancing the stability and load-bearing capacity of the cross beam and the longitudinal beam, especially at the connection part, which is usually a region with large stress. Through such reinforcement, the cross beam and the longitudinal beam can better resist deformation and damage during the transportation of the battery pack, ensuring the safety of the battery pack.

[0041] As a preferred embodiment of the present application, the transition connecting plate includes a second strengthening rib plate.

[0042] The edge of the second reinforcing rib plate abuts against the side wall of the connecting rod and the side wall of the longitudinal beam.

[0043] In the above scheme, the edge of the second reinforcing rib plate abuts against the side walls of the cross beam and the longitudinal beam, which can further improve the stability and deformation resistance of the battery transport device when subjected to lateral force, and ensure that during the battery pack transportation process, even if it is subjected to greater lateral pressure, the battery transport device can maintain its structural stability.

[0044] As a preferred embodiment of the present application, the second reinforcement part also includes a diagonal beam, which is arranged at the corner connection position of the connecting rod and the longitudinal beam, and the two ends of the diagonal beam are respectively connected to the connecting rod and the longitudinal beam, so that the diagonal beam, the connecting rod and the longitudinal beam form a triangular frame structure.

[0045] In the above scheme, the triangular frame structure formed by the cable-stayed beam, the cross beam and the longitudinal beam can provide better stability and load-bearing capacity, especially in the corner part where the cross beam and the longitudinal beam are connected, which is usually the area where the force is more concentrated. The triangular structure is stable and can effectively disperse and bear the load, thereby enhancing the structural strength and durability of the entire battery transport device.

[0046] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0047] By adopting the above solution, the chassis-type battery replacement of heavy trucks can be realized, which greatly reduces the requirements for sites and equipment of battery replacement stations compared to the existing top-mounted battery replacement method, greatly reducing land costs and equipment costs. At the same time, it can also directly avoid the battery container being placed close to the cab, which poses a greater safety hazard to the driver and the vehicle itself.

[0048] In the above scheme, the battery exchange equipment in this application integrates the functions of battery transportation and battery exchange operation, eliminating the need for a palletizer in the station, and saving the equipment cost of the palletizer compared to existing battery exchange stations for passenger car chassis. By lifting and rotating the car body relative to the support frame, the battery transport device in this application can accurately and efficiently complete the interaction of the battery pack with the battery rack at any position around it and the battery compartment at any height on the battery rack, greatly improving the transportation efficiency of the battery pack and thus improving the battery exchange efficiency.

[0049] Meanwhile, the inclination of the battery swapping body can drive the deflection of the battery swapping device to adjust the horizontal angle of the battery swapping device, so that the battery swapping device can better adapt to the inclination of the vehicle chassis itself and / or the inclination of the vehicle chassis caused by factors such as vehicle load and uneven ground at the parking position. Coupled with the rotation of the box body, it can adapt to the deviation of the parking position, parking angle or body attitude of the battery swapping vehicle, so as to ensure that the battery swapping device can fit well with the vehicle chassis during the battery swapping operation, which is beneficial to accurately and quickly disassembling and assembling the discharged battery and the fully charged battery, and improving the battery swapping efficiency. In addition, adopting the above scheme is also beneficial to the flexible arrangement of the battery racks in the battery swapping station, which can make full use of the installation space in the station, improve the space utilization rate, and reduce the requirements for the site space.

The battery swapping main body 12 is connected between the plurality of sliding mechanisms 13, and one end of the battery swapping main body 12 is rotatably connected to the corresponding sliding mechanism 13, and the other end is movably connected to the corresponding sliding mechanism 13. With this structure, when there is a difference in the lifting speeds of the sliding mechanisms 13 at both ends of the battery swapping main body 12, the battery swapping main body 12 will tilt. By tilting the battery swapping main body 12, the battery swapping device 1221 can be driven to deflect to adjust the horizontal angle of the battery swapping device 1221, so that the battery swapping device 1221 can better adapt to the tilt of the vehicle chassis itself and / or the tilt of the vehicle chassis caused by factors such as vehicle load and uneven ground at the parking position, ensuring that the battery swapping device 1221 can fit well with the vehicle chassis during the battery swapping operation, which is beneficial to accurately and quickly disassembling and assembling the depleted battery and the fully charged battery, and improving the battery swapping efficiency; at the same time, one end of the battery swapping main body 12 is rotatably connected to the sliding mechanism 13, and the other end is both rotatably connected to the sliding mechanism 13 and can move relative to the sliding mechanism 13. While facilitating the adjustment of the tilt angle by making the heights at both ends of the battery swapping main body 12 different, it is also convenient to eliminate the influence of the change in the horizontal distance between the battery swapping main body 12 and the sliding mechanism 13 when the battery swapping main body 12 tilts on the connection structure between the battery swapping main body 12 and the sliding mechanism 13, thus being beneficial to ensuring the stability of the connection structure between the battery swapping main body 12 and the sliding mechanism 13.

[0068] Preferably, a connecting shaft 1312 is provided on the end surface of one of the power swapping body 12 and the sliding mechanism 13, and a through hole 12112 or a waist-shaped hole is provided on the end surface of the other, so as to realize the rotational connection or the movable connection between the power swapping body 12 and the sliding mechanism 13.

The matching structure is simple, convenient for disassembly and assembly, and low in maintenance cost. In addition, the structures of the connecting shaft 1312, the through hole 12112 and the waist-shaped hole 12113 are simple and easy to process. The arrangement of the connecting shaft 1312, the through hole 12112 and the waist-shaped hole 12113 will not cause the structural strength of the power swapping body 12 and the sliding mechanism 13 to be excessively reduced.

[0069] As a preferred embodiment of the present application, the power swapping device 1 further includes two independent lifting drive mechanisms respectively arranged on both sides of the power swapping body 12. The two independently arranged lifting drive mechanisms are respectively connected to the sliding mechanisms 13 corresponding to both sides of the power swapping body 12, so as to independently control the lifting and moving speeds of the sliding mechanisms 13 on both sides of the power swapping body 12, and further realize the active and passive inclination of the power swapping body 12 to better adapt to the inclination of the vehicle chassis itself and / or the inclination of the vehicle chassis caused by factors such as vehicle load and uneven ground at the parking position. Preferably, the power swapping device 1 further includes a counterweight 25. The lifting drive mechanism includes a motor 21. A vertically movable counterweight 25 is provided at each column 11. The counterweight 25 is connected to the sliding mechanism 13 on its corresponding side through a chain 23. A sprocket 24 engaged with the chain 23 on its side is provided above each column 11. The motor 21 drives the synchronous shaft 22 to rotate, thereby simultaneously driving the two chains 23 on the same side of the power swapping body 12 to drive the sliding mechanism 13 to move vertically. It should be noted here that the present application does not specifically limit the installation position of the counterweight 25. Refer to Figure 1 As shown, the counterweight 25 is located at the end side adjacent to the power swapping body 12, or the counterweight 25 is located on the other side opposite to the power swapping body 12. When the counterweight 25 is arranged at the end side adjacent to the power swapping body 12, it is convenient for transporting the batteries between the battery compartments; when the counterweight 25 is arranged on the other side opposite to the power swapping body 12, it is beneficial to optimize the space utilization efficiency of the power swapping station.

[0070] In one example, refer to Figure 1As shown in the figure, the above two independently arranged lifting drive devices are respectively connected to two battery racks 3 arranged adjacent to the battery swapping device 1. The motor 21, the synchronous shaft 22 and the sprocket 24 are all arranged on the upper part of the battery rack 3, and the counterweight 25 is arranged on the side of the battery rack 3. Adopting this setting method can make full use of the installation space on the upper part of the battery rack 3, avoid setting up additional support structures, save equipment costs and at the same time save the installation space inside the battery swapping station.

[0071] Further, referring to Figure 1 As shown in the figure, the support frame includes a plurality of columns 11 respectively arranged on the peripheral sides of the battery swapping main body 12. A plurality of sliding mechanisms 13 are respectively arranged corresponding to two adjacent columns 11. The battery swapping main body 12 includes a box body 122 provided with a battery swapping device 1221 and a mounting part 121 arranged on the top surface of the box body 122. The mounting part 121 is connected between the plurality of sliding mechanisms 13. In the above solution, by arranging the columns 11, support can be provided for the sliding mechanisms 13 and the battery swapping main body 12, and the columns 11 can directly provide guidance for the lifting movement of the sliding mechanisms 13; the setting of the box body 122 can provide support and protection for the battery swapping device 1221, and at the same time can also provide protection for the battery pack during the process of the battery swapping device 1221 carrying and transporting the discharged battery or the fully charged battery, avoiding damage to the battery pack due to collision and avoiding damage to the battery pack due to falling from the battery swapping device 1221; preferably, in the above solution, the box body 122 and the mounting part 121 are rotatably connected, so as to facilitate the box body 122 to drive the battery swapping device 1221 to adjust the orientation to better adapt to different vehicle models and / or vehicle parking positions. In one example, referring to Figure 3As shown, a slewing bearing 141 and a rotation driving assembly are provided between the box body 122 and the mounting portion 121. The inner and outer rings of the slewing bearing 141 are respectively connected to the mounting portion 121 and the box body 122. The rotation driving assembly includes a gear 142 meshing with the slewing bearing 141 and a motor 21 in transmission cooperation with the gear 142. The motor 21 drives the gear 142 to rotate, thereby driving the outer ring of the slewing bearing 141 to rotate relative to the inner ring and simultaneously driving the box body 122 to rotate relative to the mounting portion 121. In the above solution, the slewing bearing 141, as a large bearing capable of bearing comprehensive loads, can not only realize the rotation of the box body 122, but also directly serve as a connecting member 12111 between the box body 122 and the mounting portion 121, eliminating the need to provide other connecting components; at the same time, the axial dimension of the slewing bearing 141 is small, which is convenient for reducing the height dimension of the connection structure between the mounting portion 121 and the box body 122, so that the height dimension of the box body 122 can be increased under the limitation of the overall height dimension standard of the device to facilitate the installation of internal components of the box body 122 and expand the accommodation space of the box body 122. Moreover, the meshing transmission of the gear 142 has the advantage of high transmission accuracy, so that the rotation angle of the box body 122 can be controlled more precisely. At the same time, the motor 21 also has the advantages of fast response speed and convenient control. It should be noted here that the above example is only the preferred example of the present application. The connection method and connection structure between the box body 122 and the mounting portion 121 in the present application are not limited to the above example, and other more different solutions can also be adopted. The present application does not make specific limitations on this.

[0072] In addition, the rotatability of the box body 122 also facilitates the flexible arrangement of the battery racks 3 around the power swapping device 1. In one example, referring to Figure 6 As shown, three rows of battery racks 3 are arranged in a triangular shape around the power swapping device 1. Adopting this arrangement makes the box body 12 in the power swapping device 1 of the present application can be fixed with a single rotation angle, that is, a single rotation of 90° can achieve an accurate turn, which is more convenient for controlling the rotation of the box body 12; and adopting this arrangement, the layout of the battery racks 3 is simple, without additional operations such as space measurement and installation angle calculation. In another example, referring to Figure 7As shown in the figure, the multi-column battery racks 3 are arranged in a polygonal shape around the periphery of the aforementioned battery swapping device 1. With this arrangement, the layout of the battery racks 3 is more flexible and more conducive to expanding the storage capacity of the battery storage device. At the same time, this layout can also make full use of the installation space inside the battery swapping station and improve the space utilization rate. In addition, with the above arrangement, the compartment 12 in the battery swapping device 1 of the present application can be fixed at a single rotation angle, but accurate space measurement and installation angle calculation are required, and the installation difficulty is relatively higher, and the installation process is relatively more time-consuming and laborious. It should also be noted that the layout of the battery racks 3 around the periphery of the battery swapping device 1 in the present application is not limited to the above examples. The above examples are only some preferred examples of the present application, and other more different battery rack arrangement methods can also be adopted. The present application does not make specific limitations on this either.

[0073] Preferably, referring to Figure 1 As shown in the figure, the number of columns 11 is four, and the support frame and the battery racks 3 provided on both sides of the aforementioned battery swapping device 1 share these four columns 11. With this arrangement, it is beneficial to simplify the structure of the battery swapping device 1, save equipment costs by eliminating a separate support structure, and at the same time, this arrangement can also shorten the distance between the compartment 122 and the battery compartments on the battery racks 3, which is conducive to improving the transfer accuracy and transfer efficiency of the battery packs. Of course, the aforementioned battery racks 3 and the support frame can also be independent of each other. The independence of the battery racks 3 and the support frame is more convenient for the flexible layout of the battery racks 3 and the disassembly, installation and maintenance of the battery swapping device 1. And with this arrangement, a scheme of synchronously rotating the support frame and the compartment 122 can also be adopted, so as to avoid the interference of the columns 11 on the rotation of the compartment 122. Continuing to refer to Figure 2 As shown in the figure, the installation part 121 includes two cross beams 1211 whose two ends are respectively arranged corresponding to the columns 11; the sliding mechanism 13 includes at least two sliders 132 respectively attached to the side walls of the columns 11 and a connecting rod 131 connecting the sliders 132 on both sides. In the above scheme, there are four columns 11, which is convenient for the grouped independent installation of the sliding mechanism 13 and the lifting drive mechanism. And with the above arrangement of the columns 11, while providing sufficient support capacity, it can also reduce the occlusion of the compartment 122 by the columns 11 in the circumferential direction, which is convenient for the compartment 122 to adjust its orientation; the setting of the connecting rod 131 between the sliders 132 can improve the structural strength of the sliding mechanism 13, and at the same time, it is also convenient to ensure the synchronization of the lifting movements of the sliders 132 at both ends of the connecting rod 131.

[0074] It should be noted here that the present application does not make specific limitations on the setting methods of the connecting shaft 1312, the through hole 12112 and the waist-shaped hole 12113.

[0075] In one example, connecting shafts 1312 are provided through the side walls of the cross beam 1211 near both ends. A bushing is fixedly provided inside the cross beam 1211 to install the connecting shafts 1312; a U-shaped lug 1311 is provided on the side wall of the connecting rod 131 facing the power exchange main body 12, and a through hole 12112 or a waist-shaped hole is provided on the lug side wall of the U-shaped lug 1311. The connecting shafts 1312 can be integrally formed with the cross beam 1211, thereby enhancing the connection strength between the connecting shafts 1312 and the cross beam 1211; by providing the bushings, the connecting shafts 1312 can be protected, and at the same time, it is convenient to lubricate between the bushings and the connecting shafts 1312, reducing the frictional loss of the connecting shafts 1312.

[0076] In another preferred example, referring to Figure 2 As shown, U-shaped lugs 1311 are provided on the side walls of the connecting rod 131 near both ends, and connecting shafts 1312 are provided through the U-shaped lugs 1311. Connecting members 12111 matching the distances between the two sliding mechanisms 13 are respectively provided at both ends of the cross beam 1211. Through holes 12112 or moving grooves are provided on the connecting members 12111. The through holes 12112 are circular holes that penetrate the connecting members 12111 and match the connecting shafts 1312, and the moving grooves are waist-shaped holes that extend along the length direction of the cross beam 1211 and penetrate the connecting members 12111. With this structure, the connecting members 12111 can be connected to the installation part 121 after the connecting members 12111 are connected. Compared with the previous solution where the connecting shafts 1312 are directly provided on the cross beam 1211, it is more convenient to realize the cooperation between the connecting shafts 1312 and the through holes 12112 and the waist-shaped holes 12113, which is beneficial to reducing the assembly difficulty.

[0077] Furthermore, referring to Figure 2 As shown, the sliding mechanism 13 includes a connecting rod 131 and vertically arranged fixing plates fixed at both ends of the connecting rod 131. At least two sliders 132 are sequentially provided on the side wall of each column 11 and one of the fixing plates along the lifting and moving direction, and a slide rail matching the sliders 132 is provided on the side wall of the other. Preferably, at least two rollers are provided on two adjacent perpendicular side walls of the fixing plate adjacent to the column 11, and rolling surfaces matching the rollers are provided on two corresponding perpendicular side walls of the column 11. In the above solution, the cooperation structure between the sliders 132 and the slide rails is simple, easy to set, and beneficial to the limit of the lifting and moving of the sliding mechanism 13; at the same time, at least two sliders 132 are sequentially provided along the lifting and moving direction, which can further limit the running track of the sliding mechanism 13, prevent deviation during the lifting process, and improve stability. At the same time, through the setting of the rollers and the rolling surfaces and the cooperation between the two, the stability of the moving path of the sliding mechanism 13 relative to the column 11 during the lifting and moving can be further ensured, which is beneficial to ensuring the adjustment accuracy of the height and the inclination angle of the power exchange device 1221.

[0078] As a preferred embodiment of the present application, refer to Figure 2 , Figure 4 and Figure 5 As shown, the mounting portion 121 also includes a plurality of longitudinal beams 1212 vertically fixedly connected to the cross beam 1211, as well as a first reinforcement portion and a second reinforcement portion. The first reinforcement portion includes a plurality of reinforcement plates 1213 connecting two adjacent longitudinal beams 1212, and the second reinforcement portion includes a plurality of transition connection plates. A transition connection plate is provided on the beam surface at the connection between the reinforcement plate 1213 and the longitudinal beam 1212. The first reinforcement portion and the second reinforcement portion are provided to improve the structural strength of the linkage portion, thereby preventing the linkage portion from being deformed or broken due to the excessive weight of the compartment 122, the telescopic mechanism provided inside the compartment 122, and the battery pack carried, thereby ensuring the safe and stable operation of the equipment; and the reinforcement plate 1213 has a simple structure and is convenient to be provided. The above-mentioned reinforcement structure will not occupy too much installation space on the upper part of the mounting plate. The reinforcement plate 1213 can be provided to realize the planning and arrangement of the installation space on the upper part of the mounting plate, which is convenient for the provision of the aforementioned additional components such as the motor 21, and can also provide partial protection for the additional components such as the motor 21.

[0079] In one example, referring to Figure 4 As shown, the transition connecting plate includes a first reinforcing rib plate 12141; the first reinforcing rib plate 12141 is disposed at the connection position of the connecting rod 131 and the longitudinal beam 1212, and is located on two upper and lower opposite beam surfaces of the connecting rod 131 and the longitudinal beam 1212. The first reinforcing rib plate 12141 is located at the connection position of the cross beam 1211 and the longitudinal beam 1212 and is disposed on two upper and lower opposite beam surfaces, which can provide additional structural support in the transverse and longitudinal directions, enhance the stability and load-bearing capacity of the cross beam 1211 and the longitudinal beam 1212, especially at the connection position, which is usually an area with greater force. Through such reinforcement, the cross beam 1211 and the longitudinal beam 1212 can better resist deformation and damage during the transportation of the battery pack, thereby ensuring the safety of the battery pack. Preferably, continue to refer to Figure 4 As shown, the transition connecting plate includes a second reinforcing rib plate 12142; the edge of the second reinforcing rib plate 12142 abuts against the side wall of the connecting rod 131 and the side wall of the longitudinal beam 1212. The edge of the second reinforcing rib plate 12142 abuts against the side wall of the cross beam 1211 and the longitudinal beam 1212, which can further improve the stability and anti-deformation ability of the battery transport device when subjected to lateral force, ensuring that during the battery pack transportation process, even if it is subjected to a large lateral pressure, the battery transport device can maintain its structural stability.

[0080] In another example, referring to Figure 5As shown, the second strengthening part further includes a stay beam 12143. The stay beam 12143 is disposed at the corner connection position of the connecting rod 131 and the longitudinal beam 1212, and both ends of the stay beam 12143 are respectively connected to the connecting rod 131 and the longitudinal beam 1212, so that the stay beam 12143, the connecting rod 131 and the longitudinal beam 1212 form a triangular frame structure. In the above solution, the triangular frame structure formed by the stay beam 12143, the cross beam 1211 and the longitudinal beam 1212 can provide better stability and load-bearing capacity. Especially at the corner part of the connection position between the cross beam 1211 and the longitudinal beam 1212, which is usually the area where the force is more concentrated, the triangular structure has stability and can effectively disperse and bear the load, enhancing the structural strength and durability of the entire battery transfer device.
