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 electric vehicle battery swap, and specifically relates to a battery transfer device and a battery storage device. BACKGROUND

[0003] With the development and popularization of new energy vehicles, battery pack fast swap technology has also developed rapidly. For large vehicles, such as heavy trucks or light trucks, the vehicle body and the load weight are very large, which leads to a higher demand for the capacity of the battery pack of the large vehicle, and only a large-capacity electric energy can support the use of the large vehicle.

[0004] In the traditional swap mode, large vehicles of new energy series are fixed on the large beam of the vehicle by the way of top lifting, and the battery container is arranged close to the cab, which causes great safety hazards to the driver and the vehicle itself during driving and top lifting swap. Moreover, if the battery fails, it will directly cause personal injury to the driver. In addition, the top lifting method has high requirements for the site of the swap station, and the swap station needs to have a large enough area to perform lifting equipment transfer and battery storage, etc., which leads to high station construction cost.

[0005] Therefore, for large vehicles, there is an urgent need for a safer and more reliable swap mode that is easy to popularize. For example, the chassis type swap mode of passenger cars is adopted. In the chassis type swap mode, the whole swap equipment needs to be controlled to move to the swap position under the swap vehicle, and then the lifting operation and the disassembly or installation of the battery pack operation are performed to complete the entire swap process. During the swap process, due to the limited space at the bottom of the swap vehicle, especially for heavy truck swap vehicles, it is difficult to drive and park on a platform higher than the ground, so the space at the bottom of the swap vehicle is more limited. If the swap equipment is used for swap, the swap equipment needs to carry the discharged battery pack or the full battery pack to move back and forth and in and out of the bottom of the swap vehicle. In order to meet the power demand of the heavy truck swap vehicle, the battery pack is very large, which greatly limits the available space of the swap equipment and the station battery storage device. In addition, the battery pack interaction between the swap equipment and the battery storage device in the prior art usually also needs to set another stacking machine to realize, which further compresses the available installation space in the station, and also prolongs the swap process, making it difficult to effectively improve the swap efficiency.

[0006] In addition, due to the large size and weight of the heavy truck, the range of the body posture adjustment in the limited space is extremely small and difficult to adjust, and the operation angle of the existing battery replacement equipment is usually fixed, which often causes the problem that the battery replacement equipment cannot be accurately connected with the battery replacement vehicle to perform the battery replacement operation due to the parking angle, parking position or body posture offset of the battery replacement vehicle in the actual battery replacement process, thereby easily causing damage to the battery pack, the body and the battery replacement equipment.

[0007] Therefore, the prior art has many drawbacks and needs to be further improved and enhanced. SUMMARY

[0063] As shown in Figures 1-5 The battery transfer device 1 provided by the application includes a fixed support frame, a liftable compartment 12, and a telescopic mechanism 121 arranged in the compartment 12 and movable outwardly. The battery transfer device 1 further includes a moving assembly 13 arranged between the support frames and movable along the support frames. The compartment 12 is rotatably connected to the moving assembly 13 to adjust the orientation of the telescopic mechanism 121. In the above scheme, the height adjustment of the compartment 12 and the telescopic mechanism 121 inside the compartment 12 can be achieved by arranging the moving assembly 13 to drive the compartment 12 to move vertically relative to the support frame, so as to adapt to different vehicle chassis of battery swap vehicles and different heights of battery pack installation areas. The rotation connection between the compartment 12 and the moving assembly 13 enables the compartment 12 and the telescopic mechanism 121 inside the compartment 12 to adjust the orientation, so as to adjust the angle between the extension direction of the telescopic mechanism 121 and the direction of the battery swap vehicle or the orientation of the battery rack 2 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 transfer. This is conducive to achieving accurate and efficient battery pack transfer between the battery swap vehicle and the battery storage device, improving the battery pack transfer efficiency, transfer safety, and ultimately the battery swap efficiency and safety.

[0064] Further, with reference to Figure 1 , Figure 2Figure 4 and Figure 5 As 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 moving part 131 includes a connecting rod 1311 and sliding parts 1312 arranged at both ends of the connecting rod 1311, the length of the connecting rod 1311 is adapted to the distance between the two upright columns 11 in the same group, and the sliding parts 1312 at both ends of the connecting rod 1311 are respectively in sliding cooperation with the two upright columns 11 in the same group. The linkage part 132 includes two cross beams 1321 respectively connected with the sliding parts 1312. Preferably, one end of the cross beam 1321 is rotatably connected with the corresponding sliding part 1312 through cooperation between the connecting shaft 1313 and the circular hole 13211, and the other end is rotatably and movably connected with the corresponding sliding part 1312 through cooperation between the connecting shaft 1313 and the waist-shaped hole 13212. By using this structure, the linkage part 132 can be tilted by changing the lifting height of the two moving parts 131, thereby driving the compartment 12 and the telescopic mechanism 121 to tilt, so that the tilting of the battery swap vehicle chassis can be adapted to more accurately complete the disassembly and assembly of the battery pack

[0068] Further, with reference to Figure 3 As shown, the battery transfer device 1 further includes a rotating mechanism arranged between the compartment 12 and the linkage part 132, the rotating mechanism includes a slewing bearing 141 assembly arranged between the mounting surface and the compartment 12, and a driving assembly for driving the slewing bearing 141 assembly to rotate.

[0069] By arranging the rotating mechanism, the smoothness and efficiency of the rotation of the compartment 12 relative to the linkage part 132 can be improved, thereby improving the battery transfer efficiency and the battery swap efficiency. At the same time, the rotatable connection between the compartment 12 and the linkage part 132 is realized by the rotating mechanism, i.e., the rotating mechanism integrates the functions of bearing the compartment 12 and driving the compartment 12 to rotate relative to the linkage, thereby saving additional connection structures and facilitating the reduction of the overall height of the device to better adapt to the heavy truck battery swap requirements. At the same time, in the above scheme, the slewing bearing 141, as a large bearing capable of bearing comprehensive load, can not only realize the rotation of the compartment 12, but also directly serve as a connecting piece between the compartment 12 and the linkage part 132, thereby eliminating the need for other connecting components to connect the compartment 12 and the linkage part 132. At the same time, the axial size of the slewing bearing 141 is small, which facilitates the reduction of the height of the connecting structure between the moving assembly 13 and the compartment 12, thereby increasing the height of the compartment 12 to facilitate the installation of internal components of the compartment 12 and expand the accommodation space of the compartment 12 under the limitation of the overall height of the device.

[0070] In one example, continuing to refer to Figure 2As shown, the linkage part 132 further comprises a mounting plate 1323 fixed to the bottom surface of the longitudinal beam 1322, the surface of the mounting plate 1323 is provided with the aforementioned mounting surface, and the driving assembly comprises a rotating shaft 144 penetrating through the mounting surface, a gear 143 arranged on the rotating shaft 144 and engaged with the rotary support assembly, and a motor 142 arranged on the top surface of the mounting plate 1323 and used to drive the rotating shaft 144 to rotate. By adopting this arrangement, the mounting space on the upper part of the mounting plate 1323 can be fully utilized, and the vertical distance between the mounting surface and the compartment 12 can be avoided from being enlarged due to the occupation of the mounting space between the compartments 12, thereby facilitating the increase of the height of the compartment 12 under the limitation of the overall height of the device, the installation of the internal components of the compartment 12, and the expansion of the accommodation space of the compartment 12, and the gear 143 has the advantage of high transmission precision, so that the angle of rotation of the compartment 12 can be more accurately controlled, and the motor 142 also has the advantages of fast response speed and convenient control.

[0071] As a preferred embodiment of the present application, referring to Figure 2 As shown, the linkage part 132 further comprises a mounting plate 1323 fixed to the bottom surface of the longitudinal beam 1322, the surface of the mounting plate 1323 is provided with the aforementioned mounting surface, and the driving assembly comprises a rotating shaft 144 penetrating through the mounting surface, a gear 143 arranged on the rotating shaft 144 and engaged with the rotary support assembly, and a motor 142 arranged on the top surface of the mounting plate 1323 and used to drive the rotating shaft 144 to rotate. By adopting this arrangement, the mounting space on the upper part of the mounting plate 1323 can be fully utilized, and the vertical distance between the mounting surface and the compartment 12 can be avoided from being enlarged due to the occupation of the mounting space between the compartments 12, thereby facilitating the increase of the height of the compartment 12 under the limitation of the overall height of the device, the installation of the internal components of the compartment 12, and the expansion of the accommodation space of the compartment 12, and the gear 143 has the advantage of high transmission precision, so that the angle of rotation of the compartment 12 can be more accurately controlled, and the motor 142 also has the advantages of fast response speed and convenient control.

[0072] In summary, in the above scheme, the structural strength of the linkage part 132 can be improved by the first reinforcing part, so that the deformation or fracture of the linkage part 132 caused by the excessive weight of the compartment 12, the telescopic mechanism 121 arranged inside the compartment 12, and the battery pack carried thereby can be avoided, and the safe and stable operation of the equipment can be ensured.

[0073] As a preferred embodiment of the present application, referring to Figure 4As shown, the linkage part 132 further comprises a second reinforcing part arranged near the moving part 131. In one example, referring to Figure 4 As shown, the second reinforcing part comprises a first reinforcing rib plate 13251 arranged at the connecting position of the cross beam 1321 and the longitudinal beam 1322 and located on the two opposite beam surfaces of the cross beam 1321 and the longitudinal beam 1322. The first reinforcing rib plate 13251 arranged at the connecting position of the cross beam 1321 and the longitudinal beam 1322 and located on the two opposite beam surfaces can provide additional structural support in the transverse and longitudinal directions, thereby enhancing the stability and load-bearing capacity of the cross beam 1321 and the longitudinal beam 1322, especially at the connecting position, which is usually a region with relatively large stress. 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, continuing to refer to Figure 4 As shown, the second reinforcing part further comprises a second reinforcing rib plate 13252, the edges of which abut against the side walls of the cross beam 1321 and the longitudinal beam 1322. The edges of the second reinforcing rib plate 13252 abutting against the side walls of the cross beam 1321 and the longitudinal beam 1322 can further improve the stability and deformation resistance of the battery transfer device 1 when subjected to lateral force, ensuring that the battery transfer device 1 can maintain its structural stability even when subjected to relatively large lateral pressure during the transportation of the battery pack.

[0074] In another example, referring to Figure 5 As shown, the second reinforcing part comprises a diagonal beam 13253 arranged at the corner connecting position of the cross beam 1321 and the longitudinal beam 1322, and the two ends of the diagonal beam 13253 are connected with the cross beam 1321 and the longitudinal beam 1322 respectively, so that the diagonal beam 13253, the cross beam 1321 and the longitudinal beam 1322 form a triangular frame structure. In this example, the triangular frame structure formed by the diagonal beam 13253, the cross beam 1321 and the longitudinal beam 1322 can provide better stability and load-bearing capacity, especially at the corner portion of the connecting position of the cross beam 1321 and the longitudinal beam 1322, which is also usually a region with relatively large 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 1.

[0075] In summary, the second reinforcing part can improve the structural strength of the linkage part 132 near the moving part 131, avoid structural deformation of the linkage part 132 due to the excessive weight of the compartment 12, the telescopic mechanism 121 and the battery pack borne by the linkage part 132, and also facilitate improving the stability of the connecting structure between the linkage part 132 and the moving part 131, thereby avoiding failure of the cooperating structure between the linkage part 132 and the moving part 131.

[0076] Further, referring to Figure 6and Figure 7 As shown in FIG. 1, the battery storage device further comprises at least one battery rack 2 arranged around the battery transfer device 1, and the battery rack 2 is provided with a plurality of battery storage positions arranged in the longitudinal direction, and the openings of the plurality of battery storage positions are all directed to the compartment 12 in the battery transfer device 1. As a preferred embodiment of the present application, a plurality of battery racks 2 are arranged around the battery transfer device 1.

[0077] In one example, referring to Figure 6 As shown in FIG. 1, the battery rack 2 is arranged in three rows in a triangular shape around the battery transfer device 1. This arrangement allows the compartment 12 in the battery transfer device 1 to be fixed at a single rotation angle, i.e., a single rotation of 90° can achieve a precise turning once, making it more convenient to control the rotation of the compartment 12. In addition, this arrangement of the battery rack 2 is simple, without the need for additional work such as space measurement and installation angle calculation.

[0078] In another example, referring to Figure 7 As shown in FIG. 1, a plurality of rows of battery racks 2 are arranged in a polygonal shape around the battery transfer device 1. This arrangement makes the arrangement of the battery rack 2 more flexible and more conducive to expanding the storage capacity of the battery storage device. At the same time, this arrangement can also make full use of the installation space inside the battery transfer device 1, improving the space utilization rate. In addition, this arrangement can also make the compartment 12 in the battery transfer device 1 fixed at a single rotation angle, but requires accurate space measurement and installation angle calculation, which is relatively more difficult to install and takes more time and effort during installation.

[0079] In summary, in the above-mentioned scheme, the arrangement of the battery rack 2 is flexible and has strong expandability, which can adapt to different installation conditions and improve the space utilization rate while increasing the storage capacity of the battery pack. The arrangement of a plurality of 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, improving the battery transfer efficiency.

[0080] As a preferred embodiment of the present application, the battery rack 2 can reuse the stand column 11 of the support frame, and referring to Figure 1As shown, two battery racks 2 are arranged opposite to each other on two sides of the compartment 12, and two support columns on each side of the compartment 12 are the aforementioned vertical columns 11. This arrangement is conducive to simplifying the structure of the battery transfer device 1, saving equipment costs by eliminating a separate support structure, and also shortening the distance between the compartment 12 and the battery positions 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 support frame can also be independent of each other, and the independent arrangement of the battery rack 2 and the support frame is more convenient for flexible arrangement of the battery rack 2 and disassembly, maintenance of the battery transfer device 1. In addition, this arrangement can also be used with a scheme in which the support frame and the compartment 12 rotate synchronously, thereby avoiding interference of the vertical columns 11 with the rotation of the compartment 12.
