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 transport device and a battery storage 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 replacement mode. For example, a chassis-type battery replacement mode for passenger cars is adopted. In the chassis-type battery replacement mode, it is necessary to control the battery replacement equipment to move as a whole to the battery replacement position under the battery replacement vehicle, and then perform lifting operations and remove or install battery pack operations to complete the entire battery replacement process. In this battery replacement process, due to the limited space at the bottom of the battery replacement vehicle, especially heavy-duty battery replacement vehicles, which are difficult to drive and park on a platform above the ground, the space at the bottom of the battery replacement vehicle is even more limited. If a battery replacement device is used for battery replacement, the battery replacement device needs to carry the low-power battery pack or the fully charged battery pack to move back and forth and in and out of the bottom of the battery replacement vehicle during the battery replacement process. In order to meet the power requirements of heavy-duty battery replacement vehicles, the battery packs are very large, which leads to a great restriction on the available space for the battery replacement equipment and the battery storage device in the station. In addition, in the prior art, the battery pack interaction between the battery replacement equipment and the battery storage device usually requires a separate stacker to be implemented, which further compresses the available installation space in the station, and also prolongs the battery replacement process, making it difficult to effectively improve the battery replacement efficiency.

[0006] In addition, due to the large size and weight of heavy trucks, the range of adjustment of the body posture in a limited space is extremely small and difficult to adjust, and the operating angle of the existing battery swapping equipment is usually fixed. This leads to the problem that in the actual battery swapping process, the battery swapping equipment cannot accurately dock with the battery swapping vehicle to perform the battery swapping operation due to the parking angle, parking position or the body's own posture deviation of the battery swapping vehicle, which can easily cause damage to the battery pack, body and battery swapping equipment.

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

[0008] The present application provides a battery transfer device and a battery storage device. The battery transfer device is provided with a rotatable compartment and a telescopic mechanism arranged inside the compartment. The battery storage device includes a plurality of battery racks arranged around the battery transfer device. The arrangement of the battery racks is flexible and by cooperating with the rotatable compartment, the battery transfer device can interact with battery racks at any position for battery packs, thereby improving the battery transfer efficiency and solving at least one of the above-mentioned technical problems.

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

[0010] In the first aspect, the present application provides a battery transport device, which includes a fixed support frame, a liftable and movable body, and a telescopic mechanism arranged in the body and capable of being telescoped and moved outward. The battery transport device also includes a movable component arranged between the support frames and capable of being lifted and lowered along the support frames. The body can be rotatably connected to the movable component to adjust the direction of the telescopic mechanism.

[0011] In the above scheme, a moving assembly is provided to drive the box to move up and down along the support frame, thereby adjusting the height of the telescopic mechanism. At the same time, the box and the moving assembly are rotatably connected, which facilitates the adjustment of the angle of the box, thereby adjusting the extension angle of the telescopic mechanism. When the position of the battery to be transported or the parking position of the battery swap vehicle has a deflection angle, the telescopic mechanism can be accurately positioned and extended through rotation adjustment, which is conducive to efficient battery transport and completion of the battery swap action. At the same time, the adoption of the above scheme makes the battery rack setting method flexible and highly scalable, and can adapt to the installation conditions of different installation environments. While improving space utilization, it can also increase the battery pack storage capacity and make full use of the installation space on the side of the battery transport device.

[0012] As a preferred embodiment of the present application, the moving assembly is arranged above the box, and the top surface of the box can be rotatably connected to the bottom surface of the moving assembly, so that the box drives the telescopic mechanism to rotate synchronously to adjust the direction of the telescopic mechanism.

[0013] In the above scheme, the mobile component is arranged above the box, and the rotation control is realized by the top surface of the box, so that no additional structure is required on the bottom surface of the box, and it can be set close to the ground, so that it can adapt to the chassis of different models and batteries at different heights, which is conducive to improving the scope of application of the battery transfer device of this application.

[0014] As a preferred embodiment of the present application, the support frame includes a plurality of columns formed on the outer periphery of the box.

[0015] The moving assembly includes at least two moving parts that are arranged in contact with the side walls of two adjacent columns and can be lifted and lowered, and a linkage part connected between the at least two moving parts. The box body can be rotatably connected to the bottom surface of the linkage part.

[0016] In the above scheme, by setting up the columns, stable support and limitation can be provided for the moving assembly and the car body, thereby improving the stability of the connection structure between the car body and the moving assembly, and avoiding the centrifugal force generated by the rotation of the car body relative to the moving assembly, which may cause the moving assembly to shift or deflect, and is beneficial to ensuring the stability of the relative rotation between the moving assembly and the car body; by setting up a moving part in the moving assembly to cooperate with the columns to realize the lifting function, and by setting up a linkage part to be connected with the car body for rotation, it plays a role in positioning and supporting the car body, which is beneficial to improving the stability of the connection mechanism between the car body and the linkage part.

[0017] As a preferred embodiment of the present application, the linkage part includes at least two cross beams whose ends are respectively connected to the corresponding moving parts and at least two longitudinal beams connected between the at least two cross beams, and the bottom surfaces of the at least two longitudinal beams are formed with mounting surfaces for mounting the car body.

[0018] In the above solution, the linkage part is provided with at least two cross beams for connecting with the moving parts on both sides. At least two longitudinal beams are provided to form a mounting surface for mounting the compartment body. At the same time, the longitudinal beams also strengthen the overall structural strength of the linkage part to prevent deformation.

[0019] As a preferred embodiment of the present application, the battery transport device also includes a rotating mechanism arranged between the body and the linkage part, and the rotating mechanism includes a slewing bearing assembly arranged between the mounting surface and the body and a driving assembly for driving the slewing bearing assembly to rotate.

[0020] In the above scheme, by providing a rotating mechanism, the smoothness and efficiency of the rotation of the car body relative to the linkage part can be improved, which is conducive to improving the battery transportation efficiency and battery replacement efficiency; at the same time, the rotatable connection between the car body and the linkage part is achieved by the rotating mechanism, that is, the rotating mechanism integrates the functions of carrying the car body and driving the car body to rotate relative to the linkage, saving additional connection structure, which is conducive to reducing the overall height of the equipment and better adapting to the battery replacement needs of heavy trucks;

[0021] At the same time, in the above scheme, the slewing bearing is a large bearing that can withstand comprehensive loads. It can not only realize the rotation of the car body, but also directly serve as a connecting part between the car body and the linkage part, eliminating the need to set up other connecting parts to connect the car body and the linkage part; at the same time, the axial dimension of the slewing bearing is small, which is convenient for reducing the height dimension of the connection structure between the moving component and the car body, thereby increasing the height dimension of the car body within the limitation of the overall height dimension standard of the device to facilitate the installation of internal components of the car body and expand the accommodating space of the car body.

[0022] As a preferred embodiment of the present application, the linkage portion further includes a mounting plate fixed to at least the bottom surface of the longitudinal beam, and the mounting surface is formed on the surface of the mounting plate.

[0023] The driving assembly includes a rotating shaft passing through the mounting surface, a gear provided on the rotating shaft and meshing with the slewing bearing assembly, and a motor provided on the top surface of the mounting plate and used for driving the rotating shaft to rotate.

[0024] In the above scheme, this setting method can make full use of the installation space on the upper part of the mounting plate, and can avoid occupying the installation space between the mounting surface and the compartment, resulting in an increase in the vertical distance between the mounting surface and the compartment, which is beneficial to increase the height of the compartment within the limitation of the overall height size standard of the device to facilitate the installation of internal components of the compartment and expand the accommodating space of the compartment. The gear meshing transmission has the advantage of high transmission accuracy, so that the angle of rotation of the compartment can be controlled more accurately. At the same time, the motor also has the advantages of fast response speed and easy control.

[0025] As a preferred embodiment of the present application, the linkage portion further includes a first reinforcement portion provided at least corresponding to the mounting surface.

[0026] In the above scheme, the structural strength of the linkage part can be improved by strengthening the structure, 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.

[0027] As a preferred embodiment of the present application, the first reinforcement portion includes a plurality of reinforcement plates, both ends of the reinforcement plates are fixedly connected to the longitudinal beams at both ends respectively, the bottom of the reinforcement plates is fixedly connected to the mounting plate, and / or, the first reinforcement portion includes a plurality of reinforcement plates arranged between the longitudinal beams, and a transition connection plate is also provided on the beam surface at the connection between the reinforcement plates and the longitudinal beams.

[0028] In the above scheme, 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 installation plate. The horizontal and / or vertical reinforcement plates can be used to plan and arrange the installation space on the upper part of the installation plate, which is convenient for the installation of additional components such as the aforementioned motor, and can also provide partial protection for additional components such as the motor.

[0029] As a preferred embodiment of the present application, the linkage portion further includes a second reinforcement portion arranged close to the moving portion.

[0030] In the above scheme, by setting the second reinforcement part, the structural strength of the linkage part close to the moving part can be improved, thereby preventing the linkage part from being deformed due to the excessive weight of the compartment, telescopic mechanism and battery pack it carries. At the same time, it is also beneficial to improve the stability of the connection structure between the linkage part and the moving part, and avoid failure of the matching structure between the linkage part and the moving part.

[0031] As a preferred embodiment of the present application, the second reinforcement portion includes a first reinforcement rib plate;

[0032] Wherein, the first reinforcing rib plate is arranged at the connection position of the cross beam and the longitudinal beam, and is located on two upper and lower opposite beam surfaces of the cross beam and the longitudinal beam.

[0033] 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.

[0034] As a preferred embodiment of the present application, the second reinforcement portion further includes a second reinforcing rib plate;

[0035] Wherein, the edge of the second reinforcing rib abuts against the side wall of the cross beam and the side wall of the longitudinal beam.

[0036] 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.

[0037] As a preferred embodiment of the present application, the second reinforcement portion includes a diagonal beam, which is arranged at the corner connection position of the cross beam and the longitudinal beam, and the two ends of the diagonal beam are respectively connected to the cross beam and the longitudinal beam, so that the diagonal beam, the cross beam and the longitudinal beam form a triangular frame structure.

[0038] 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.

[0039] In the second aspect, the present application also provides a battery storage device, which includes the battery transfer device as described above, and the battery storage device also includes at least one battery rack arranged on the periphery of the battery transfer device, and the battery rack is provided with a plurality of battery positions distributed along the longitudinal direction, and the battery positions have a bay opening facing the compartment body.

[0040] In the above scheme, the battery rack is set up flexibly and has strong scalability. It can adapt to the installation conditions of different installation environments, improve space utilization, and increase the storage capacity of battery packs. The circumferential arrangement of multiple battery racks around the battery transfer device can make full use of the installation space on the side of the battery transfer device, and by cooperating with the rotatable compartment, the battery transfer device can interact with battery racks at any position for battery packs, thereby improving battery transfer efficiency.

[0041] As a preferred embodiment of the present application, a plurality of battery racks are provided, and the plurality of battery racks are arranged circumferentially around the battery transfer device, and the battery racks and the support frame reuse the columns; or, the battery racks and the support frame are independent of each other.

[0042] In the above scheme, the reuse of columns for the battery rack and the support frame further improves the structural strength between the battery rack and the battery transfer device, which is beneficial to improving the safety of battery transfer; at the same time, this setting method is beneficial to simplifying the structure of the battery rack and / or support frame, saving equipment costs; the battery rack and the support frame are independent of each other, which facilitates the overall rotation of the battery transfer device, avoids interference of the columns on the rotation of the car body, and is more conducive to the flexible turning of the car body and the flexible arrangement of the battery rack.

[0043] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0044] 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.

[0045] In the above scheme, the battery transfer device in this application integrates the functions of battery transfer and battery replacement operation, eliminating the need for a palletizer in the station, and also eliminating the equipment cost of the palletizer compared to existing battery replacement stations for passenger car chassis. By lifting and rotating the car body relative to the support frame, the battery transfer 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 transfer efficiency of the battery pack and thus improving the battery replacement efficiency. It also makes the arrangement of the battery racks in the battery storage device in this application more flexible, which can make full use of the installation space in the station, improve space utilization, and reduce the requirements for site space.

[0046] At the same time, the rotation of the body can adapt to the parking position, parking angle or the deviation of the battery-swapping vehicle's own posture, so that the telescopic mechanism can always be accurately docked with the battery-swapping vehicle during the battery-swapping process, thereby achieving accurate and efficient battery swapping and reducing the risk of damage to the battery pack, body and battery-swapping equipment during the battery-swapping process.

[0063] like Figure 1-5 As shown, the present application provides a battery transport device 1, which includes a fixed support frame, a liftable and movable body 12, and a telescopic mechanism 121 arranged in the body 12 and telescopically movable outward. The battery transport device 1 also includes a moving component 13 arranged between the support frames and liftable and movable along the support frames. The body 12 can be rotatably connected to the moving component 13 to adjust the direction of the telescopic mechanism 121. In the above scheme, by setting a moving component 13 to drive the compartment 12 to move up and down relative to the support frame in the vertical direction, the height adjustment of the compartment 12 and the telescopic mechanism 121 inside it can be achieved, so that it can adapt to the different heights of the vehicle chassis and battery pack installation areas of different battery swap vehicles; through the rotational connection between the compartment 12 and the moving component 13, the compartment 12 and the telescopic mechanism 121 inside it in this application can adjust their direction, so that the angle between the extension direction of the telescopic mechanism 121 and the direction of the battery swap vehicle body or the direction of the battery rack 2 can be adjusted to eliminate the adverse effects of the angle deviation between the battery storage position, the battery swap vehicle parking position and the predetermined position on the battery transportation, which is conducive to the accurate and efficient battery pack transportation between the battery swap vehicle and the battery storage device, and improves the battery pack transportation efficiency, transportation safety and the ultimate battery swap efficiency and battery swap safety.

[0064] Further, refer to Figure 1 、 Figure 2 Figure 4 and Figure 5As shown, the movable assembly 13 is disposed above the compartment 12, and the top surface of the compartment 12 is rotatably connected to the bottom surface of the movable assembly 13, so that the compartment 12 drives the telescopic mechanism 121 to rotate synchronously, thereby adjusting the orientation of the telescopic mechanism 121. Positioning the movable assembly 13 above the compartment 12 and enabling rotational control via the top surface of the compartment 12 eliminates the need for any additional structure on the bottom surface of the compartment 12, allowing it to be positioned close to the ground. This allows it to accommodate chassis of different vehicle models and batteries at different heights, thereby broadening the applicability of the battery transporter 1 of the present application.

[0065] As a preferred embodiment of the present application, the support frame includes a plurality of columns 11 formed on the outer periphery of the body 12. The movable assembly 13 includes at least two movable portions 131 disposed in contact with the side walls of two adjacent columns 11 and capable of lifting and lowering, and a linkage portion 132 connected between the at least two movable portions 131. The body 12 is rotatably connected to the bottom surface of the linkage portion 132. The linkage portion 132 includes at least two crossbeams 1321, each of which is connected at both ends to the corresponding moving portions 131, and at least two longitudinal beams 1322 connected between the at least two crossbeams 1321. The bottom surfaces of the at least two longitudinal beams 1322 are formed with mounting surfaces for mounting the body 12.

[0066] In the above scheme, by providing the upright column 11, stable support and positioning can be provided for the moving assembly 13 and the body 12, thereby improving the stability of the connection structure between the body 12 and the moving assembly 13, and preventing the centrifugal force generated by the rotation of the body 12 relative to the moving assembly 13 from causing the moving assembly 13 to shift or deflect, which is conducive to ensuring the stability of the relative rotation between the moving assembly 13 and the body 12; by providing the moving part 131 in the moving assembly 13 to cooperate with the upright column 11 to realize the lifting function, and by providing the linkage part 132 to be rotatably connected to the body 12, it plays a role in positioning and supporting the body 12, which is conducive to improving the stability of the connection mechanism between the body 12 and the linkage part 132. The linkage part 132 is provided with at least two cross beams 1321 for connecting with the moving parts 131 on both sides, and at least two longitudinal beams 1322 are provided to form a mounting surface for mounting the body 12. At the same time, the longitudinal beams 1322 also strengthen the overall structural strength of the linkage part 132 to prevent deformation.

[0067] In one example, referring to Figure 1 As shown, there are four columns 11, two of which are arranged in a group on both sides of the battery transport device 1, and two moving parts 131 are provided, and the two moving parts 131 are respectively arranged on two groups of columns 11. Figure 2As shown, the movable part 131 includes a connecting rod 1311 and a sliding part 1312 provided at both ends of the connecting rod 1311. The length of the connecting rod 1311 is adapted to the spacing between the two columns 11 in the same group, and the sliding parts 1312 at both ends of the connecting rod 1311 respectively slide with the two columns 11 in the same group. The linkage part 132 includes two beams 1321 connected to the sliding parts 1312 at both ends. Preferably, one end of the beam 1321 is rotatably connected to the corresponding sliding part 1312 through the cooperation between the connecting shaft 1313 and the circular hole 13211, and the other end is rotatably connected to the corresponding sliding part 1312 through the cooperation between the connecting shaft 1313 and the waist-shaped hole 13212, and also realizes a movable connection. With this structure, the linkage part 132 can be tilted by the different lifting heights of the movable parts 131 on both sides, thereby driving the body 12 and the telescopic mechanism 121 to be tilted, so as to adapt to the tilt of the chassis of the battery-swap vehicle to more accurately complete the disassembly and assembly of the battery pack.

[0068] Further, refer to Figure 3 As shown, the battery transport device 1 also includes a rotating mechanism provided between the compartment 12 and the linkage portion 132 , and the rotating mechanism includes a slewing support 141 component provided between the mounting surface and the compartment 12 and a driving component for driving the slewing support 141 component to rotate.

[0069] By setting up a rotating mechanism, the smoothness and rotation efficiency of the car body 12 relative to the linkage part 132 can be improved, which is beneficial to improving the battery transportation efficiency and battery replacement efficiency; at the same time, the rotatable connection between the car body 12 and the linkage part 132 is realized by the rotating mechanism, that is, the rotating mechanism integrates the functions of carrying the car body 12 and driving the car body 12 to rotate relative to each other, saving additional connecting structure, which is beneficial to reducing the overall height of the equipment and better adapting to the battery replacement needs of heavy trucks; at the same time, in the above scheme, the slewing bearing 141 is a large bearing that can withstand comprehensive loads. It can not only realize the rotation of the car body 12, but also directly serve as a connecting part between the car body 12 and the linkage part 132, eliminating the need to set up other connecting parts to connect the car body 12 and the linkage part 132; 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 moving component 13 and the car body 12, so that the height dimension of the car body 12 can be increased within the limitation of the overall height dimension standard of the device to facilitate the installation of internal components of the car body 12 and expand the accommodation space of the car body 12.

[0070] In one example, continue with Figure 2As shown, the linkage portion 132 further includes a mounting plate 1323 fixed to the bottom surface of the longitudinal beam 1322, the surface of the mounting plate 1323 being formed with the aforementioned mounting surface, and the drive assembly including a rotating shaft 144 provided through the mounting surface, a gear 143 provided on the rotating shaft 144 and meshing with the slewing bearing assembly, and a motor 142 provided on the top surface of the mounting plate 1323 and configured to drive the rotating shaft 144 to rotate. This arrangement allows for full utilization of the installation space above the mounting plate 1323 and avoids occupying the installation space between the mounting surface and the car body 12, thereby increasing the vertical spacing between the mounting surface and the car body 12. This facilitates increasing the height dimension of the car body 12 within the overall height dimension standard of the device, thereby facilitating the installation of components within the car body 12 and expanding the storage space of the car body 12. The meshing transmission of the gear 143 has the advantage of high transmission precision, thereby enabling more precise control of the rotation angle of the car body 12. The motor 142 also has the advantages of fast response speed and convenient control.

[0071] As a preferred embodiment of this application, refer to Figure 2 As shown, the linkage portion 132 in the present application also includes a first reinforcement portion corresponding to at least the aforementioned mounting surface. In one example, continue to refer to Figure 2 As shown, the first reinforcement portion includes a plurality of reinforcement plates 1324, and both ends of the plurality of reinforcement plates 1324 are respectively connected to the two longitudinal beams 1322, and the bottoms of the reinforcement plates 1324 are fixedly connected to the mounting plates 1323. Preferably, the first reinforcement portion includes a plurality of reinforcement plates 1324 disposed between the longitudinal beams 1322, and a transition connecting plate is further disposed on the beam surface where the reinforcement plates 1324 connect to the longitudinal beams 1322. In this example, the provision of the transition connecting plate can enhance the stability of the connection structure between the reinforcement plates 1324 and the longitudinal beams 1322, thereby enhancing the reinforcing effect of the reinforcement plates 1324 on the linkage portion 132 structure. In addition, in the above example, the reinforcing plate 1324 has a simple structure and is easy to install. The above-mentioned reinforcing structure will not occupy too much installation space on the upper part of the mounting plate 1323, and the horizontal and / or vertical reinforcing plates 1324 can be used to plan and arrange the installation space on the upper part of the mounting plate 1323, which is convenient for the installation of additional components such as the aforementioned motor 142, and can also provide partial protection for additional components such as the motor 142.

[0072] In summary, in the above scheme, the structural strength of the linkage part 132 can be improved by setting the first reinforcement part, thereby avoiding deformation or breakage of the linkage part 132 due to the excessive weight of the compartment 12, the telescopic mechanism 121 set inside the compartment 12 and other components, and the battery pack carried, thereby ensuring the safe and stable operation of the equipment.

[0073] As a preferred embodiment of this application, refer to Figure 4As shown, the linkage portion 132 further includes a second reinforcement portion disposed near the moving portion 131. In one example, referring to Figure 4 As shown, the second reinforcement portion includes a first reinforcing rib plate 13251. The first reinforcing rib plate 13251 is arranged at the connection position of the cross beam 1321 and the longitudinal beam 1322, and is located on the two upper and lower beam surfaces of the cross beam 1321 and the longitudinal beam 1322. The first reinforcing rib plate 13251 is located at the connection position of the cross beam 1321 and the longitudinal beam 1322 and is arranged on the two upper and lower beam surfaces, which can provide additional structural support in the horizontal and longitudinal directions, enhance the stability and load-bearing capacity of the cross beam 1321 and the longitudinal beam 1322, especially at the connection position, which is usually an area with greater force. Through such reinforcement, the cross beam 1321 and the longitudinal beam 1322 can better resist deformation and damage during the transportation of the battery pack, ensuring the safety of the battery pack. Preferably, continue to refer to Figure 4 As shown, the second reinforcement portion further includes a second reinforcing rib 13252, the edges of which abut against the side walls of the crossbeam 1321 and the side walls of the longitudinal beam 1322. The abutment of the edges of the second reinforcing rib 13252 against the side walls of the crossbeam 1321 and longitudinal beam 1322 further enhances the stability and deformation resistance of the battery transporter 1 when subjected to lateral forces, ensuring that the battery transporter 1 maintains its structural stability even under significant lateral pressure during battery pack transport.

[0074] In another example, referring to Figure 5 As shown, the second reinforcement portion includes a diagonal beam 13253, which is disposed at the corner connecting the horizontal beam 1321 and the longitudinal beam 1322. The ends of the diagonal beam 13253 are respectively connected to the horizontal beam 1321 and the longitudinal beam 1322, so that the diagonal beam 13253, the horizontal beam 1321, and the longitudinal beam 1322 form a triangular frame structure. In this exemplary embodiment, the triangular frame structure formed by the diagonal beam 13253, the horizontal beam 1321, and the longitudinal beam 1322 can provide better stability and load-bearing capacity, especially at the corner portion where the horizontal beam 1321 and the longitudinal beam 1322 are connected, which is usually an area with concentrated force. The triangular structure provides stability and can effectively distribute and bear the load, thereby enhancing the structural strength and durability of the entire battery transporter 1.

[0075] In summary, by providing a second reinforcement part, the structural strength of the linkage part 132 near the movable part 131 can be improved, thereby preventing the linkage part 132 from being deformed due to the excessive weight of the compartment 12, the telescopic mechanism 121 and the battery pack it carries. At the same time, it is also beneficial to improve the stability of the connection structure between the linkage part 132 and the movable part 131, thereby preventing the failure of the matching structure between the linkage part 132 and the movable part 131.

[0076] Further, refer to Figure 6and Figure 7 As shown, the present application also discloses a battery storage device, which includes the battery transport device 1 as described above, and also includes at least one battery rack 2 arranged around the battery transport device 1, the battery rack 2 being provided with a plurality of battery positions distributed longitudinally, and the openings of the plurality of battery positions are all oriented toward the compartment 12 in the battery transport device 1. As a preferred embodiment of the present application, a plurality of battery racks 2 are provided, and the plurality of battery racks 2 are arranged around the circumference of the battery transport device 1.

[0077] In one example, referring to Figure 6 As shown, the aforementioned battery racks 2 are arranged in three rows, arranged in a triangular shape around the aforementioned battery transporter 1. This arrangement allows the body 12 of the battery transporter 1 of the present application to have a fixed single rotation angle, that is, a single 90° rotation can achieve a precise turn, making it easier to control the rotation of the body 12. This arrangement also simplifies the arrangement of the battery racks 2, eliminating the need for additional work such as space measurement and installation angle calculation.

[0078] In another example, referring to Figure 7 As shown, multiple rows of battery racks 2 are arranged in a polygonal shape around the circumference of the aforementioned battery transporter 1. This arrangement provides greater flexibility in the layout of the battery racks 2 and is more conducive to expanding the storage capacity of the battery storage device. It also fully utilizes the installation space within the battery transporter 1, improving space utilization. Furthermore, this arrangement also allows the compartment 12 in the battery transporter of this application to have a fixed single rotation angle. However, this requires precise spatial measurement and installation angle calculation, making installation more difficult and time-consuming.

[0079] In summary, in the above scheme, the setting method of the battery rack 2 is flexible and highly scalable, and can adapt to the installation conditions of different installation environments. While improving space utilization, it can also increase the storage capacity of battery packs; the circumferential arrangement of multiple battery racks 2 around the battery transfer device 1 can make full use of the installation space on the side of the battery transfer device 1, and by cooperating with the rotatable compartment 12, the battery transfer device 1 can interact with the battery rack 2 at any position for battery packs, thereby improving battery transfer efficiency.

[0080] As a preferred embodiment of the present application, the aforementioned battery rack 2 can reuse the column 11 with the support frame, and continue to refer to Figure 1As shown, the two battery racks 2 are relatively arranged on both sides of the compartment 12, and the two supporting columns of the two battery racks 2 facing the side of the compartment 12 are the aforementioned columns 11. This arrangement is conducive to simplifying the structure of the battery transfer device 1, eliminating a separate supporting structure and saving equipment costs. At the same time, the arrangement can also shorten the distance between the compartment 12 and the battery compartment on the battery rack 2, which is conducive to improving the transfer accuracy and efficiency of the battery pack. Of course, the aforementioned battery rack 2 and the support frame can also be independent of each other. The independence of the battery rack 2 and the support frame makes it more convenient for the flexible arrangement of the battery rack 2 and the disassembly and maintenance of the battery transfer device 1. In addition, this arrangement can also adopt a solution in which the support frame and the compartment 12 rotate synchronously, thereby avoiding interference of the columns 11 with the rotation of the compartment 12.
