Description

[0001] This application claims priority to Chinese patent application No. 202410380046.4, filed on March 29, 2024. This application incorporates the entirety of the aforementioned patent application. Technical Field

[0002] The present application belongs to the technical field of battery replacement for electric vehicles, and specifically relates to a battery replacement device. Background Art

[0003] With the development and popularization of new energy vehicles, battery pack quick-swap technology has also developed rapidly. For large vehicles, such as heavy trucks and light trucks, the heavy weight of the body and cargo leads to higher battery pack capacity requirements, requiring a sufficiently large capacity of electricity to support the operation of large vehicles.

[0004] In traditional battery swapping, large new energy vehicles use a top-lift method to secure large battery containers to the vehicle's beams. These containers are located close to the cab, posing significant safety risks to both the driver and the vehicle during operation and during top-lift battery swapping. Furthermore, battery failures can directly harm the driver. Furthermore, the top-lift method places high demands on the site for battery swap stations, requiring sufficient space for lifting equipment to transport and store batteries, resulting in high construction costs.

[0005] Therefore, for large vehicles, there is an urgent need for a safer, more reliable and easy-to-popularize battery swap mode. For example, a chassis-type battery swap mode for passenger cars is adopted. In the chassis-type battery swap mode, it is necessary to control the battery swap equipment to move as a whole to the battery swap position under the battery swap vehicle, and then perform lifting operations and remove or install battery pack operations to complete the entire battery swap process. In this battery swap process, due to the limited space at the bottom of the battery swap vehicle, especially heavy-duty battery swap vehicles that are difficult to drive and park on platforms above the ground, the bottom space of the battery swap vehicle is even more limited. If a battery swap device is used for battery swapping, the battery swap device needs to carry the depleted battery pack or the fully charged battery pack to move back and forth and in and out of the bottom of the battery swap vehicle during the battery swap process. In order to meet the power requirements of heavy-duty battery swap vehicles, the battery packs are very large, which leads to a great restriction on the available space for the battery swap equipment and the battery storage device in the station. At this time, if you want to increase the available space for the battery swapping equipment, you can only move the battery swapping equipment in the space sunken from the ground. Due to the multiple driving of heavy-duty battery swapping vehicles before and after battery swapping, the ground structure under this method will inevitably become unreliable and difficult to bear the multiple loads of the battery swapping vehicles, reducing the life of the equipment structure and posing a safety hazard to the battery swapping vehicles.

[0006] In addition, due to the large size and weight of heavy trucks, the range of adjustment of the body posture of heavy trucks in a limited space is extremely small and difficult to adjust. At the same time, the body of a heavy truck under load or after long-term load use will usually tilt to a certain extent, and the existing battery swap mechanism that can extend into the bottom of the heavy truck for battery swap operations can usually only maintain a horizontal state. This leads to the fact that in the actual battery swap process, the battery swap structure cannot be accurately coordinated with the vehicle chassis to complete the disassembly and assembly of the battery pack due to the tilt of the heavy truck body, which can easily cause damage to the battery pack, body and battery swap mechanism, and is not conducive to improving the battery swap efficiency.

[0007] This shows that the many drawbacks of the prior art need to be further improved and enhanced. Summary of the Invention

[0008] The present application provides a battery swapping device, which can drive the deflection of the battery swapping device to adjust the horizontal angle of the battery swapping device by tilting the battery swapping body, 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 in the parking position, ensuring that the battery swapping device can fit well with the vehicle chassis when performing the battery swapping operation, which is conducive to the accurate and rapid disassembly and assembly of depleted batteries and fully charged batteries, improving the battery swapping efficiency, and solving at least one of the above-mentioned technical problems.

[0009] The technical solutions adopted in this application are:

The battery exchange device also comprises a plurality of sliding mechanisms slidably arranged on the side walls of a plurality of columns of the support frame. The battery exchange body is connected between the plurality of sliding mechanisms, and one end of the battery exchange 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 scheme, the tilting of the battery-exchanging body can drive the deflection of the battery-exchanging device to adjust the horizontal angle of the battery-exchanging device, so that the battery-exchanging 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 in the parking position, ensuring that the battery-exchanging device can fit well with the vehicle chassis when performing the battery-exchanging operation, which is conducive to accurate and rapid disassembly and assembly of low-charge batteries and fully-charged batteries, and improves the battery-exchanging efficiency; at the same time, one end of the battery-exchanging 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 tilt angle by making the two ends of the battery-exchanging body different in height, it is also convenient to eliminate the influence of the change in the horizontal distance between the battery-exchanging body and the sliding mechanism when the battery-exchanging body is tilted on the connection structure between the battery-exchanging body and the sliding mechanism, which is conducive to ensuring the stability of the connection structure between the battery-exchanging 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 exchange body and the sliding mechanism, and a through hole or a waist-shaped hole is provided on the other end face, thereby realizing a rotational connection or a movable connection between the battery exchange body and the sliding mechanism.

[0013] In the above scheme, the rotational connection between the battery exchange body and the sliding mechanism can be achieved through the cooperation between the connecting shaft and the through hole, and the rotational connection and movable connection between the battery exchange body and the sliding mechanism can be achieved through the cooperation between the connecting shaft and the waist-shaped hole. The cooperation structure is simple, easy to disassemble and assemble, and has low maintenance cost. The structure of the connecting shaft, through hole and waist-shaped hole is simple and easy to process. The setting of the connecting shaft, through hole and waist-shaped hole will not cause the structural strength of the battery exchange 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 sides of the battery replacement body.

[0015] The plurality of sliding mechanisms are respectively provided corresponding to two adjacent columns.

[0016] The battery exchange body includes a compartment provided with the battery exchange device and a mounting portion provided on the top surface of the compartment, and the mounting portion is connected between the plurality of sliding mechanisms.

[0017] In the above scheme, the setting of the columns can provide support for the sliding mechanism and the battery exchange body, and the columns can directly provide guidance for the lifting and lowering movement of the sliding mechanism; the setting of the box can provide support and protection for the battery exchange device, and can also provide protection for the battery pack during the process of the battery exchange device carrying and transporting low-charged batteries or fully charged batteries, to avoid collision damage to the battery pack and to avoid damage to the battery pack from falling from the battery exchange device; preferably, in the above scheme, the box and the mounting part are rotatably connected, so as to facilitate the box to drive the battery exchange device to adjust its direction, so as to better adapt to different vehicle models and / or parking positions.

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

[0019] The battery exchange equipment also includes a counterweight block, and the lifting drive mechanism includes a motor. Each of the columns is provided with a vertically movable counterweight block, and the counterweight block is connected to the sliding mechanism on its corresponding side through a chain. A sprocket is provided above each column to cooperate with the chain on its side for transmission. The motor drives the synchronous shaft to rotate, thereby simultaneously driving the two chains located on the same side of the battery exchange body to drive the sliding mechanism to move vertically.

[0020] In the above scheme, two independent lifting drive mechanisms are set up to independently control the lifting height on both sides of the battery swap body, so that the battery swap body can be tilted 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 precise control of the lifting height and tilt angle of the battery swap device; the setting of the counterweight block can provide a safety measure for the battery swap device and the battery pack it carries, to avoid motor failure causing the battery swap device and the battery it carries to fall and be damaged directly.

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

[0022] In the above scheme, there are two settings for the counterweight block. One is to be set on the end side adjacent to the battery swap body to facilitate the transportation of batteries between battery compartments. The other is to be set on the other side opposite to the battery swap body to optimize the space utilization efficiency of the battery swap station.

[0023] As a preferred embodiment of the present application, the number of the columns is four, and the mounting portion includes two beams with two ends respectively arranged corresponding to the columns;

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

[0025] In the above scheme, four columns are provided, which is convenient for the independent installation of the sliding mechanism and the lifting drive mechanism in groups, and the columns are arranged in the above manner. While providing sufficient support capacity, it can also reduce the obstruction of the car body by the columns in the circumferential direction, making it convenient for the car body to adjust its direction; the setting of the connecting rod between the sliders can enhance the structural strength of the sliding mechanism, and it is also convenient to ensure the synchronization of the lifting and lowering movements of the sliders at both ends of the connecting rod.

[0026] As a preferred embodiment of the present application, the connecting shaft is provided through the side walls of the beam near both ends, and a shaft sleeve is fixed inside the beam to install the connecting shaft; a U-shaped lug is provided on the side wall of the connecting rod facing the battery exchange body, and the through hole or the waist-shaped hole is provided on the lug side wall of the U-shaped lug.

[0027] In the above scheme, the connecting shaft can be integrally formed with the crossbeam, thereby enhancing the connection strength between the connecting shaft and the crossbeam; by providing a shaft sleeve, the connecting shaft can be protected, and lubrication between the shaft sleeve and the connecting shaft is also facilitated, thereby reducing the friction loss of the connecting shaft.

[0028] As a preferred embodiment of the present application, a U-shaped lug is provided on the side wall near the two ends of the connecting rod, a connecting shaft is passed through the U-shaped lug, and connecting pieces matching the spacing between the two sliding mechanisms are respectively provided at both ends of the beam, and a through hole or a movable groove is provided on the connecting piece, the through hole is a circular hole passing through the connecting piece and matching the connecting shaft, and the movable groove is a waist-shaped hole extending along the length direction of the beam and passing through the connecting piece.

[0029] With the above structure, the connecting part can be connected to the mounting part after the connecting part is connected. Compared with the aforementioned solution of directly setting the connecting shaft on the beam, it is more convenient to realize the matching of the connecting shaft with the through hole and the waist-shaped hole, which is conducive to reducing the difficulty of assembly.

[0030] As a preferred embodiment of the present application, the sliding mechanism includes a connecting rod and a vertically arranged fixed plate fixed at both ends of the connecting rod, and at least two of the sliding blocks are sequentially provided on the side walls of each of the columns and one of the fixed plates along the lifting and lowering direction, and a sliding rail cooperating with the sliding block is provided on the other side wall.

[0031] In the above scheme, the matching structure between the slider and the slide rail is simple, easy to set up and conducive to limiting the lifting and lowering movement of the sliding mechanism; at the same time, at least two of the sliders are arranged in sequence along the lifting and lowering direction, which can further limit the running trajectory 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 vertical side walls of the fixing plate adjacent to the column, and rolling surfaces cooperating with the rollers are provided on two mutually vertical side walls corresponding to the column.

[0033] In the above scheme, the setting of the roller and the rolling surface and the cooperation between the two can further ensure the stability of the moving path when the sliding mechanism moves up and down relative to the column, which is conducive to ensuring the adjustment accuracy of the height of the battery exchange device and the adjustment accuracy of the tilt angle.

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

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

[0036] The second reinforcement portion includes a plurality of transition connection plates, and the transition connection plates are provided on the beam surface at the connection between the reinforcement plate and the longitudinal beam.

[0037] In the above scheme, the structural strength of the linkage part can be improved by setting the first reinforcement part and the second reinforcement part, thereby avoiding deformation or breakage of the linkage part due to the excessive weight of the compartment, the telescopic mechanism set inside the compartment and other components, and the battery pack carried, thereby ensuring the safe and stable operation of the equipment; and the structure of the reinforcement plate is simple and easy to set up. The above reinforcement structure will not occupy too much installation space on the upper part of the mounting plate. By setting the reinforcement plate, the planning and arrangement of the installation space on the upper part of the mounting plate can be realized, which is convenient for the setting of the aforementioned motor and other additional components, and can also provide partial protection for the motor and other additional components.

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

[0039] The first reinforcing rib plate is arranged at the connection position of the connecting rod and the longitudinal beam, and is located on two upper and lower opposite beam surfaces of the connecting rod and the longitudinal beam.

[0040] In the above solution, the first reinforcing ribs are located at the junction of the crossbeam and longitudinal beams and are installed on two opposing beam surfaces. They provide additional structural support in both the horizontal and vertical directions, enhancing the stability and load-bearing capacity of the crossbeam and longitudinal beams, especially at the junction, which is typically subjected to greater stress. This reinforcement helps the crossbeam and longitudinal beams better resist deformation and damage during battery pack transportation, ensuring the safety of the battery pack.

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

[0042] The edge of the second reinforcing rib 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 longitudinal beam, which can further improve the stability and deformation resistance of the battery transfer device when subjected to lateral force, and ensure that during the battery pack transfer process, even if it is subjected to large lateral pressure, the battery transfer 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 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] This solution enables chassis-based battery swapping for heavy trucks, significantly reducing the site and equipment requirements for battery swapping stations compared to existing ceiling-mounted battery swapping methods, significantly reducing land and equipment costs. It also avoids the significant safety hazards posed by placing battery containers close to the cab, which can pose a significant risk 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. Compared with the existing battery exchange stations for passenger car chassis-type battery exchange, the equipment cost of the palletizer is also eliminated. 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 battery packs with battery racks at any position around it and battery compartments at any height on the battery rack, greatly improving the transportation efficiency of the battery packs and thus improving the battery exchange efficiency.

[0049] At the same time, the tilting 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 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. Combined with the rotation of the upper body, it can adapt to the parking position, parking angle or the deviation of the vehicle body's own posture of the battery-swapping vehicle, thereby ensuring that the battery-swapping device can fit well with the vehicle chassis when performing the battery-swapping operation, which is conducive to the accurate and rapid disassembly and assembly of low-charge batteries and fully charged batteries, and improves the efficiency of battery-swapping. In addition, the above scheme is also conducive to the flexible arrangement of battery racks in the battery-swapping station, which can make full use of the installation space in the station, improve space utilization, and reduce the requirements for site space.

[0067] Reference Figure 1-7 As shown, the present application discloses a battery exchange device 1, which includes a support frame, a battery exchange body 12 arranged between the support frames and capable of being raised and lowered, and a battery exchange device 1221 arranged in the battery exchange body 12 and capable of being telescopically moved to the outside of the support frame. The battery exchange device 1 also includes a plurality of sliding mechanisms 13 that can be slidably arranged on the side walls of a plurality of columns 11 of the support frame. The battery exchange body 12 is connected between the plurality of sliding mechanisms 13, and one end of the battery exchange 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 and lowering speeds of the sliding mechanisms 13 at both ends of the battery-changing body 12, the battery-changing body 12 will be tilted. The tilt of the battery-changing body 12 can drive the battery-changing device 1221 to deflect to adjust the horizontal angle of the battery-changing device 1221, so that the battery-changing 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-changing device 1221 can fit well with the vehicle chassis when performing the battery-changing operation, which is conducive to accurate and rapid disassembly. Install low-charged batteries and fully-charged batteries to improve the battery replacement efficiency; at the same time, one end of the battery replacement 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 it is convenient to make the heights of the two ends of the battery replacement body 12 different to achieve the adjustment of the tilt angle, it is also convenient to eliminate the influence of the change in the horizontal distance between the battery replacement body 12 and the sliding mechanism 13 when the battery replacement body 12 is tilted on the connection structure between the battery replacement body 12 and the sliding mechanism 13, which is beneficial to ensure the stability of the connection structure between the battery replacement body 12 and the sliding mechanism 13.

[0068] Preferably, one of the end faces of the battery replacement main body 12 and the sliding mechanism 13 is provided with a connecting shaft 1312, and the other end face is provided with a through hole 12112 or a waist-shaped hole, so as to realize the rotary connection or movable connection between the battery replacement main body 12 and the sliding mechanism 13. The rotary connection between the battery replacement main body 12 and the sliding mechanism 13 can be realized through the cooperation between the connecting shaft 1312 and the through hole 12112, and the rotary connection and movable connection between the battery replacement main body 12 and the sliding mechanism 13 can be realized through the cooperation between the connecting shaft 1312 and the waist-shaped hole 12113. The cooperation structure is simple, easy to disassemble and assemble, and low in maintenance cost. In addition, the structure of the connecting shaft 1312, the through hole 12112 and the waist-shaped hole 12113 is simple and easy to process, and 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 battery replacement main body 12 and the sliding mechanism 13 to be excessively reduced.

[0069] As a preferred embodiment of the present application, the battery replacement equipment 1 further comprises two independent lifting driving mechanisms respectively arranged on both sides of the battery replacement main body 12. The two independently arranged lifting driving mechanisms are respectively connected with the corresponding sliding mechanisms 13 on both sides of the battery replacement main body 12, so as to realize the independent control of the lifting movement speed of the sliding mechanisms 13 on both sides of the battery replacement main body 12, and further realize the active and passive tilting of the battery replacement main body 12 to better adapt to the tilting of the vehicle chassis itself and / or the tilting of the vehicle chassis caused by factors such as the vehicle load, the parking position and the uneven ground. Preferably, the battery replacement equipment 1 further comprises a counterweight 25, and the lifting driving mechanism comprises a motor 21. A vertically movable counterweight 25 is arranged at each column 11. The counterweight 25 is connected with the sliding mechanism 13 on the corresponding side through a chain 23. A sprocket 24 is arranged above each column 11 and cooperates with the chain 23 on the side to drive. The motor 21 drives the synchronous shaft 22 to rotate, thereby simultaneously driving the two chains 23 on the same side of the battery replacement main body 12 to drive the sliding mechanism 13 to move vertically. It should be noted that the present application does not limit the position of the counterweight 25. Referring to Figure 1 The counterweight 25 is located on the side adjacent to the battery replacement main body 12, or the counterweight 25 is located on the other side opposite to the battery replacement main body 12. The counterweight 25 is arranged on the side adjacent to the battery replacement main body 12, which is convenient for the transportation of batteries between the battery compartments. The counterweight 25 is arranged on the other side opposite to the battery replacement main body 12, which is beneficial to optimize the space utilization efficiency of the battery replacement station.

[0070] In one example, referring to Figure 1As shown, the two independently arranged lifting drive devices are respectively connected to the two battery racks 3 arranged near the battery swapping equipment 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. This arrangement can make full use of the installation space on the upper part of the battery rack 3, avoid the need for a separate support structure, save equipment costs, and save installation space inside the battery swap station.

[0071] Further, refer to Figure 1 As shown, the support frame includes a plurality of columns 11 respectively arranged on the sides of the battery exchange body 12, and a plurality of sliding mechanisms 13 are respectively arranged corresponding to two adjacent columns 11. The battery exchange body 12 includes a body 122 provided with a battery exchange device 1221 and an installation portion 121 provided on the top surface of the body 122. The installation portion 121 is connected between the plurality of sliding mechanisms 13. In the above scheme, the column 11 is provided to provide support for the sliding mechanism 13 and the battery exchange body 12, and the column 11 can directly provide guidance for the lifting and lowering movement of the sliding mechanism 13; the arrangement of the compartment 122 can provide support and protection for the battery exchange device 1221, and can also provide protection for the battery pack during the process of the battery exchange device 1221 carrying and transporting low-charge batteries or fully-charged batteries, to avoid collision damage to the battery pack and to avoid damage to the battery pack from falling from the battery exchange device 1221; preferably, in the above scheme, the compartment 122 and the mounting portion 121 are rotatably connected, so as to facilitate the compartment 122 to drive the battery exchange device 1221 to adjust its direction, so as to better adapt to different vehicle models and / or parking positions. In one example, referring to Figure 3As shown, a slewing bearing 141 and a rotation drive assembly are provided between the 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 body 122. The rotation drive assembly includes a gear 142 meshing with the slewing bearing 141 and a motor 21 transmission-coordinated 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 at the same time driving the body 122 to rotate relative to the mounting portion 121. In the above scheme, the slewing bearing 141 is a large bearing capable of bearing a comprehensive load. It not only enables the rotation of the housing 122, but also directly serves as a connecting member 12111 between the housing 122 and the mounting portion 121, eliminating the need for additional connecting components. At the same time, the slewing bearing 141 has a small axial dimension, which facilitates reducing the height dimension of the connection structure between the mounting portion 121 and the housing 122. This allows the height dimension of the housing 122 to be increased within the overall height dimension standard of the device, facilitating the installation of internal components and expanding the storage space of the housing 122. Furthermore, the meshing transmission of the gear 142 has the advantage of high transmission precision, allowing for more precise control of the rotation angle of the housing 122. At the same time, the motor 21 also has advantages such as fast response speed and convenient control. It should be noted that the above examples are only preferred examples of this application. The connection method and connection structure between the housing 122 and the mounting portion 121 in this application are not limited to the above examples. Other different solutions can also be adopted, and this application does not specifically limit them.

[0072] In addition, the rotatable compartment 122 also facilitates the flexible arrangement of the battery rack 3 around the battery replacement device 1. In one example, referring to Figure 6 As shown, three rows of battery racks 3 are arranged in a triangular shape on the periphery of the battery exchange device 1. This arrangement allows the body 12 in the battery exchange device 1 of this application to have a fixed single rotation angle, that is, a single rotation of 90 degrees can achieve a precise turn, which is more convenient for controlling the rotation of the body 12; and this arrangement makes the arrangement of the battery racks 3 simple, without the need for additional work such as space measurement and installation angle calculation. In another example, refer to Figure 7As shown, multiple rows of battery racks 3 are arranged in a polygonal shape around the circumference of the aforementioned battery exchange device 1. With this arrangement, the arrangement of the battery rack 3 is more flexible and more conducive to expanding the storage capacity of the battery storage device. At the same time, the above arrangement can also make full use of the installation space inside the battery exchange station and improve space utilization. In addition, the above arrangement can also make the compartment 12 in the battery exchange device 1 of this application fixed at a single rotation angle, but it requires precise space measurement and installation angle calculation, and the installation difficulty is relatively higher, and the installation process is relatively more time-consuming and labor-intensive. It should also be noted that the arrangement of the battery rack 3 on the circumference of the battery exchange device 1 in this application is not limited to the above examples. The above examples are only some preferred examples of this application. Other more different battery rack arrangements can also be used, and this application does not make specific limitations on this.

[0073] Preferably, refer to Figure 1 As shown, there are four columns 11, and the support frame and the aforementioned battery racks 3 arranged on both sides of the battery exchange device 1 reuse these four columns 11. This setting method is conducive to simplifying the structure of the battery exchange device 1, eliminating a separate supporting structure to save equipment costs, and at the same time, the setting method can also shorten the distance between the compartment 122 and the battery compartment on the battery rack 3, which is conducive to improving the transportation accuracy and efficiency of the battery pack. Of course, the aforementioned battery rack 3 and the support frame can also be independent of each other. The independence of the battery rack 3 and the support frame makes it more convenient for the flexible arrangement of the battery rack 3 and the disassembly and maintenance of the battery exchange device 1. In addition, this setting method can also adopt a solution in which the support frame and the compartment 122 rotate synchronously, thereby avoiding interference of the columns 11 with the rotation of the compartment 122. Continue to refer to Figure 2 As shown, the mounting portion 121 includes two crossbeams 1211, each of which is provided at both ends corresponding to the column 11; the sliding mechanism 13 includes at least two sliders 132, each of which is fitted on the side wall of the column 11, and a connecting rod 131 connecting the sliders 132 on both sides. In the above scheme, four columns 11 are provided, which facilitates the grouped and independent installation of the sliding mechanism 13 and the lifting drive mechanism. The above arrangement of the columns 11 can provide sufficient support capacity while also reducing the obstruction of the column 11 on the circumferential direction of the box 122, making it easier for the box 122 to adjust its direction; the provision of the connecting rod 131 between the sliders 132 can enhance the structural strength of the sliding mechanism 13, and also facilitates the synchronization of the lifting and lowering 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 any specific limitation on the arrangement of the connecting shaft 1312 , the through hole 12112 and the waist-shaped hole 12113 .

[0075] In one example, a connecting shaft 1312 is provided through the side walls of the crossbeam 1211 near both ends, and a sleeve is fixed inside the crossbeam 1211 to install the connecting shaft 1312; a U-shaped lug 1311 is provided on the side wall of the connecting rod 131 facing the battery exchange 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 shaft 1312 can be integrally formed with the crossbeam 1211, thereby enhancing the connection strength between the connecting shaft 1312 and the crossbeam 1211; the provision of the sleeve can protect the connecting shaft 1312, and at the same time facilitate lubrication between the sleeve and the connecting shaft 1312, thereby reducing the friction loss of the connecting shaft 1312.

[0076] In another preferred example, referring to Figure 2 As shown, the side walls of the connecting rod 131 near both ends are provided with U-shaped lugs 1311, and the U-shaped lugs 1311 are penetrated by a connecting shaft 1312. The two ends of the crossbeam 1211 are respectively provided with connecting pieces 12111 that match the spacing between the two sliding mechanisms 13. The connecting piece 12111 is provided with a through hole 12112 or a movable groove. The through hole 12112 is a circular hole that passes through the connecting piece 12111 and matches the connecting shaft 1312. The movable groove is a waist-shaped hole that extends along the length direction of the crossbeam 1211 and passes through the connecting piece 12111. With this structure, the connecting piece 12111 can be connected to the mounting portion 121 after the connecting piece 12111 is connected. Compared with the aforementioned solution in which the connecting shaft 1312 is directly provided on the crossbeam 1211, it is more convenient to achieve the matching of the connecting shaft 1312 with the through hole 12112 and the waist-shaped hole 12113, which helps to reduce the difficulty of assembly.

[0077] Further, refer to Figure 2 As shown, the sliding mechanism 13 includes a connecting rod 131 and a vertically arranged fixed plate fixed at both ends of the connecting rod 131. At least two sliders 132 are sequentially provided on the side walls of each column 11 and one of the fixed plates along the lifting direction, and a slide rail that cooperates with the slider 132 is provided on the other side wall. Preferably, at least two rollers are provided on the two perpendicular side walls adjacent to the fixed plate and the column 11, and rolling surfaces that cooperate with the rollers are provided on the two mutually perpendicular side walls corresponding to the column 11. In the above scheme, the matching structure between the slider 132 and the slide rail is simple, easy to set up, and conducive to limiting the lifting and lowering movement of the sliding mechanism 13. At the same time, the sequential provision of at least two sliders 132 along the lifting direction can further limit the running trajectory of the sliding mechanism 13, prevent deviation during the lifting process, and improve stability. At the same time, the setting of the rollers and the rolling surface and the cooperation between the two can further ensure the stability of the moving path of the sliding mechanism 13 when it is lifted and lowered relative to the column 11, thereby facilitating the adjustment accuracy of the height and tilt angle of the battery exchange device 1221.

[0078] As a preferred embodiment of this application, refer to Figure 2 、 Figure 4 and Figure 5 As shown, the mounting portion 121 also includes a plurality of longitudinal beams 1212 fixedly connected vertically to the crossbeam 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 where the reinforcement plates 1213 connect to the longitudinal beams 1212. The provision of the first reinforcement portion and the second reinforcement portion can enhance the structural strength of the linkage portion, thereby preventing deformation or breakage of the linkage portion due to excessive weight of the compartment 122, the telescopic mechanism provided inside the compartment 122, and the battery pack carried, thereby ensuring safe and stable operation of the equipment. The reinforcement plate 1213 has a simple structure and is easy to set up. The use of the above-mentioned reinforcement structure does not occupy too much installation space on the upper portion of the mounting plate. The provision of the reinforcement plate 1213 can realize the planning and arrangement of the installation space on the upper portion of the mounting plate, facilitate the installation of additional components such as the aforementioned motor 21, and also provide partial protection for 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 provided at the connection position of the connecting rod 131 and the longitudinal beam 1212, and is located on the 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 crossbeam 1211 and the longitudinal beam 1212 and is provided on the upper and lower opposite beam surfaces, which can provide additional structural support in the horizontal and vertical directions, enhance the stability and load-bearing capacity of the crossbeam 1211 and the longitudinal beam 1212, especially at the connection position, which is usually an area with greater force. Through such reinforcement, the crossbeam 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 12142; the edges of the second reinforcing rib 12142 abut against the side walls of the connecting rod 131 and the side walls of the longitudinal beam 1212. The edges of the second reinforcing rib 12142 abut against the side walls of the cross beam 1211 and the longitudinal beam 1212, further improving the stability and deformation resistance of the battery transporter when subjected to lateral forces, ensuring that the battery transporter maintains its structural stability even when subjected to significant lateral pressure during battery pack transport.

[0080] In another example, referring to Figure 5As shown, the second reinforcing part further comprises a cable-stayed beam 12143, which is arranged at the corner connecting position of the link rod 131 and the longitudinal beam 1212, and the two ends of the cable-stayed beam 12143 are connected with the link rod 131 and the longitudinal beam 1212 respectively, so that the cable-stayed beam 12143, the link rod 131 and the longitudinal beam 1212 form a triangular frame structure. In the above scheme, the triangular frame structure formed by the cable-stayed beam 12143, the cross beam 1211 and the longitudinal beam 1212 can provide better stability and carrying capacity, especially at the corner part of the connecting position of the cross beam 1211 and the longitudinal beam 1212, which is usually also a region with relatively concentrated stress. The triangular structure has stability and can effectively disperse and bear the load, thereby enhancing the structural strength and durability of the entire battery transfer device.
