[0001] The present invention relates to the field of vehicle battery replacement technology, and in particular to a battery adapter, a power battery and a vehicle. Background Art

[0002] At present, the battery box installation methods of electric vehicles are generally divided into fixed and replaceable types. Among them, the fixed battery box is fixedly installed on the electric vehicle, and the electric vehicle is directly used as the charging object during charging. The replaceable battery box is generally installed in a detachable manner. The battery box can be removed and replaced with a new battery box at any time. This process is called battery swapping. Compared with the charging mode, the battery swapping mode has the characteristics of short battery swapping time, high operating efficiency, long battery life, and low difficulty in building charging and swapping stations. It has outstanding advantages in energy replenishment and travel rate, avoiding the long waiting time for the vehicle to be fully charged, which is conducive to the development of new energy vehicles.

[0059] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", and "right" are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of description and simplifying operations, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0060] As Figures 1 to 4 shown, this embodiment provides a battery adapter device, which includes a battery mounting frame 1, an adapter mounting member 3, and one or more vehicle body mounting beams 2.

[0061] Referring to Figure 1 , in this embodiment, the power battery 200 is detachably connected to the battery mounting frame 1 through a locking mechanism 400. The locking mechanism 400 includes a battery-end locking assembly 401 and an adapter-end locking assembly 402 (as Figure 14 shown). Among them, the battery-end locking assembly 401 is provided on the power battery 200, and the adapter-end locking assembly 402 is provided on the battery mounting frame 1. By repeatedly disassembling and assembling between the battery-end locking assembly 401 and the adapter-end locking assembly 402, the replacement of the power battery 200 can be realized.

[0062] Specifically referring to Figure 1 , Figure 2 and Figure 3 , a plurality of adapter-end locking assemblies 402 are provided on the battery mounting frame 1. The plurality of adapter-end locking assemblies 402 are distributed circumferentially and in the middle of the battery mounting frame 1, and are respectively locked or unlocked with the battery-end locking assemblies 401 on the power battery 200. The battery mounting frame 1 is fixed to the vehicle-end longitudinal beam 300 through the vehicle body mounting beam 2 and the adapter mounting member 3, thereby realizing the fixation of the power battery 200 to the vehicle body. By repeatedly disassembling and assembling the power battery 200 and the battery mounting frame 1, vehicle battery swapping can be realized. The setting of the battery adapter device 100, as the installation medium between the power battery 200 and the vehicle body, can meet the requirement of converting it into a battery-swapping type vehicle without changing the original structure of the vehicle, without major modifications to the vehicle production line, and reducing R & D and production costs. In addition, the vehicle body mounting beam 2 of the battery adapter device 100 is installed on the vehicle-end longitudinal beam 300 through the adapter mounting member 3 in an adjustable position along the length direction of the vehicle-end longitudinal beam 300. During installation, the installation position of the battery adapter device 100 can be adaptively adjusted, which can tolerate a certain manufacturing and assembly error, ensuring that the battery adapter device 100 can be successfully installed on the vehicle body, with stronger flexibility and practicability.

[0063] In addition, transfer end locking components 402 are provided along the circumferential direction and at the middle position of the battery installation frame 1, and all the transfer end locking components 402 are locked with the battery end locking components 401 in a one-to-one correspondence. Compared with the prior art in which only vehicle end locking components are provided on the vehicle end longitudinal beam 300, more transfer end locking components 402 with reasonable distribution can be provided on the battery installation frame 1 of the present invention, effectively improving the stability of the power battery 200 after being installed on the vehicle body. Furthermore, the provision of the transfer mounting member 3 makes the connection between the battery installation frame 1 and the vehicle end longitudinal beam 300 more convenient. Compared with the technical solution of directly connecting the vehicle body installation beam 2 with the vehicle end longitudinal beam 300, the operation difficulty is reduced and the disassembly and assembly are more smooth.

[0064] It should be noted that one or more vehicle body installation beams 2 can be provided, as long as they can be connected to the vehicle end longitudinal beam 300 with adjustable positions. Providing multiple vehicle body installation beams 2 can ensure the connection strength between the battery transfer device 100 and the vehicle end longitudinal beam 300 and ensure the installation stability, which can be selected according to specific requirements in actual design. Similarly, one transfer mounting member 3 can be provided on the vehicle body installation beam 2, or multiple transfer mounting members 3 can be provided along the length direction of the vehicle body installation beam 2.

[0065] See Figure 3 and Figure 9 , the power battery 200 includes a lower box body 201 and two end upper box covers 202 arranged at intervals. Both the lower box body 201 and the end upper box covers 202 are shell-like structures with cavities recessed therein. The two end upper box covers 202 are respectively buckled at both ends of the lower box body 201 to form a chamber for accommodating the battery module. See Figure 5 and Figure 6 , the battery installation frame 1 includes a frame main body 11 and two accommodating frames 12 arranged at intervals. The frame main body 11 includes a plurality of border beams 111 connected end to end in sequence, and the border beams 111 are detachably connected to the lower box body 201 of the power battery 200. Specifically, the transfer end locking components 402 on the circumference of the battery installation frame 1 are arranged on the border beams 111, and the battery end locking components 401 are arranged on the lower box body 201. Further, the frame main body 11 is in a rectangular structure, which includes four border beams 111 connected end to end in sequence. The transfer end locking components 402 are arranged on the border beams 111, and the battery end locking components 401 are arranged on the lower box body 201 of the power battery 200. The two accommodating frames 12 respectively protrude from both ends of the frame main body 11 and both define accommodating chambers 121. The openings of the accommodating chambers 121 face downward. When installing the power battery 200, the two end upper box covers 202 of the power battery 200 extend into the accommodating chambers 121 of the two accommodating frames 12 in a one-to-one correspondence, as Figure 3 and Figure 4After the power battery 200 is installed, the two end upper box covers 202 are accommodated in the corresponding accommodation chambers 121, and the accommodation frame 12 can protect the end upper box covers 202 from collision.

[0066] The receiving frame 12 includes a square frame structure 122 and a plurality of support beams 123 spaced apart along the circumference of the square frame structure 122. The ends of the support beams 123 away from the square frame structure 122 are connected to the frame beams 111. That is, the square frame structure 122 is spaced apart above the frame beams 111. Specifically, the frame body 11 also includes two inner connecting beams 112. Figure 5 、 Figure 6 as well as Figure 7 The inner connecting beam 112 is arranged inside the rectangular structure formed by the four frame beams 111 and is used to install the accommodating frame 12. Figure 5 In the orientation, multiple support beams 123 on one side of the frame structure 122 are connected to the frame beam 111, and multiple support beams 123 on the other side are connected to the inner connecting beam 112, that is, the inner connecting beam 112 provides an installation fulcrum for the multiple support beams 123 on the other side of the frame structure 122.

[0067] Further, see [[ID=�3]]Figure 5 、 Figure 6 as well as Figure 7 , a reinforcing crossbeam 124 and / or a first reinforcing oblique beam is provided inside the frame structure 122. In this embodiment, there are multiple reinforcing crossbeams 124 spaced apart and arranged in parallel in the frame structure 122 to ensure that the strength of the containing frame 12 is sufficient and not easily deformed. In other embodiments, the number and distribution of the reinforcing crossbeams 124 and the first reinforcing oblique beams can be set as needed. For example, a first reinforcing oblique beam is provided between the reinforcing crossbeam 124 and the frame structure 122 to form a triangular reinforcing structure, which effectively improves the deformation resistance of the frame structure 122. A second reinforcing oblique beam 125 is provided between the frame structure 122 and the frame beam 111, and a plurality of second reinforcing oblique beams 125 are provided to form multiple triangular reinforcing structures between the frame structure 122 and the frame beam 111 to ensure the overall strength and stability of the containing frame 12.

[0068] like Figure 1 As shown, the upper box covers 202 at the two ends of the power battery 200 are spaced apart along the width of the vehicle-end longitudinal beam 300. Accordingly, the two receiving frames 12 are spaced apart along the width of the vehicle-end longitudinal beam 300. Each of the two receiving frames 12 is connected to a vehicle-mounting beam 2 on one side facing the other. The vehicle-mounting beam 2 is connected to multiple support beams 123 on one side of the receiving frame 12. The two vehicle-mounting beams 2 are each mounted on a corresponding vehicle-end longitudinal beam 300, ensuring that the vehicle-end longitudinal beam 300 and the battery adapter 100 are evenly loaded.

[0069] See Figure 4 and Figure 9 , the power battery 200 further includes an upper middle cover 203 disposed between the two end upper covers 202 and buckled to the middle part of the lower box body 201. As shown in Figure 4 , the upper middle cover 203 includes a plurality of convex shells 2031 arranged at intervals along the length direction of the vehicle end longitudinal beam 300. In this embodiment, three convex shells 2031 are provided, which are recessed from the upper middle cover 203, and the connecting part is between two adjacent convex shells 2031. The battery mounting frame 1 further includes two inner mounting beams 13 arranged at intervals along the length direction of the vehicle end longitudinal beam 300. The two inner mounting beams 13 are connected between the two accommodating frames 12. See Figure 5 , the inner mounting beam 13 is specifically connected to the inner connecting beam 112, and avoidance openings 14 are defined between the inner mounting beam 13 and the frame beam 111 and between two adjacent inner mounting beams 13. The number of the avoidance openings 14 corresponds to the number of the convex shells 2031. The above-mentioned adapter end locking assembly 402 is arranged on the inner mounting beam 13. See Figure 11 , and a battery end locking assembly 401 is arranged at the middle position of the lower box body 201. When installing the power battery 200, the power battery 200 can be lifted by the battery swapping device, so that the end upper cover 202 on the power battery 200 penetrates into the accommodating frame 12, and the three convex shells 2031 of the upper middle cover 203 pass through the avoidance openings 14 one by one. When the power battery 200 is lifted in place, the battery end locking assembly 401 on the lower box body 201 is correspondingly connected to the adapter end locking assembly 402 on the frame beam 111 and the inner mounting beam 13, so as to realize the locking of the power battery 200. As shown in Figure 4 , after the power battery 200 is installed, the inner mounting beam 13 is located directly above the above-mentioned connecting part.

[0070] The locking of the power battery 200 is completed by correspondingly connecting a plurality of battery end locking assemblies 401 on it to the adapter end locking assemblies 402 on the frame beam 111 and the inner mounting beam 13, fixing both the edge position and the middle position of the power battery 200 to ensure that the power battery 200 is firmly fixed after installation. In addition, it can be understood that the convex shells 2031 are inherent in the power battery 200 itself. When the number of them increases, the number of the inner mounting beams 13 also increases accordingly, as long as the number of the formed avoidance openings 14 corresponds to the number of the convex shells 2031.

[0071] As shown in Figure 6 , Figure 7 and Figure 8As shown, a third reinforcing diagonal beam 15 is connected between the inner mounting beam 13 and the receiving frame 12 to form a triangular reinforcing structure at the end position of the inner mounting beam 13, ensuring the stability of the inner mounting beam 13. One or multiple third reinforcing diagonal beams 15 can be provided and distributed circumferentially along the inner mounting beam 13. In this embodiment, three third reinforcing diagonal beams 15 are provided at both ends of the inner mounting beam 13 to form triangular reinforcing structures on both opposite sides and the upper side of the inner mounting beam 13.

[0072] Continue to refer to Figure 6 and Figure 7 , a fourth reinforcing diagonal beam 16 is provided between the frame beam 111 and the inner connecting beam 112, and the fourth reinforcing diagonal beam 16 is located inside the avoidance opening 14 to increase the connection stability between the frame beam 111 and the inner connecting beam 112.

[0073] In this embodiment, optionally, the vehicle body mounting beam 2 is provided in the middle of the receiving frame 12. Refer to Figure 5 , Figure 6 , and Figure 7 , a first reinforcing upright beam 21 connected to the receiving frame 12 is provided on the upper side of the vehicle body mounting beam 2, and multiple first reinforcing upright beams 21 are provided at intervals along the length direction of the vehicle body mounting beam 2; a second reinforcing upright beam 22 connected to both the receiving frame 12 and the frame beam 111 is provided on the lower side of the vehicle body mounting beam 2, and the second reinforcing upright beam 22 is provided at the end of the vehicle body mounting beam 2. By providing the first reinforcing upright beam 21 and the second reinforcing upright beam 22, the connection strength and stability between the vehicle body mounting beam 2 and the battery mounting frame 1 can be improved, and the vehicle body mounting beam 2 can be prevented from being overloaded and deformed.

[0074] As Figure 6 and Figure 7 shown, optionally, five adapter mounting parts 3 are provided along the length of each vehicle body mounting beam 2. As Figure 15 shown, each adapter mounting part 3 includes a first plate 31 and a second plate 32 connected vertically. The first plate 31 is connected to the vehicle body mounting beam 2, and the second plate 32 is connected to the vehicle end longitudinal beam 300 with adjustable position. One or more triangular reinforcing plates 33 (four are provided in this embodiment) are provided between the first plate 31 and the second plate 32. While the adapter mounting part 3 realizes the adjustable position of the vehicle body mounting beam 2, it also has high strength itself, ensuring the stable connection between the vehicle body mounting beam 2, the vehicle end longitudinal beam 300 and the battery mounting frame 1. The number of adapter mounting parts 3 and the number of triangular reinforcing plates 33 on each adapter mounting part 3 can be set according to requirements.

[0075] As Figure 13 and Figure 14As shown, the adapter end locking assembly 402 includes a fixed box 4022 and a locking nut 4021. The fixed box 4022 is fixed to the frame beam 111 by threaded members, and a limiting cavity is defined on the fixed box 4022. The locking nut 4021 is movably arranged in the limiting cavity. The battery end locking assembly 401 includes a locking bolt 4011, and the locking bolt 4011 is rotatably arranged on the lower box body 201 of the power battery 200. When the power battery 200 is lifted to a preset position, the locking bolt 4011 can be rotated by an unlocking and locking gun, so that the locking bolt 4011 passes through the frame beam 111 and is threadedly screwed into the locking nut 4021. The locking nut 4021 is movably arranged in the limiting cavity. When the locking bolt 4011 is just inserted into the locking nut 4021, the locking nut 4021 can move adaptively to be centered with the locking bolt 4011, avoiding rigid contact between the locking bolt 4011 and the locking nut 4021 due to misalignment.

[0076] Further, referring to Figure 13 , the battery end locking assembly 401 further includes an installation sleeve 4012 and a connecting plate 4013. The installation sleeve 4012 is fixedly penetrated through the power battery 200, and the lower end of the locking bolt 4011 is rotatably penetrated through the installation sleeve 4012. The connecting plate 4013 is annularly arranged at the lower end of the installation sleeve 4012. The connecting plate 4013 and the power battery 200 can be installed by bolts to realize the connection between the battery end locking assembly 401 and the power battery 200.

[0077] Referring to Figure 13 and Figure 14 , an installation hole 1111 is vertically and penetratingly arranged on the frame beam 111, and a bushing 1112 is arranged in the installation hole 1111. The upper and lower surfaces of the bushing 1112 are flush with the upper and lower surfaces of the frame beam 111. The locking bolt 4011 can pass through the bushing 1112 and be threadedly screwed into the locking nut 4021. After the locking bolt 4011 is tightened, the frame beam 111 is squeezed between the fixed box 4022 and the installation sleeve 4012. Since the upper and lower surfaces of the bushing 1112 are flush with the upper and lower surfaces of the frame beam 111, the bushing 1112 can bear the pressure on the frame beam 111 caused by threaded screwing, avoiding the frame beam 111 from being crushed and deformed.

[0078] Specifically, the second plate 32 and the vehicle end longitudinal beam 300 are connected by fasteners. Referring to Figure 15 , a plurality of first connection holes 301 are arranged at intervals along the length direction of the vehicle end longitudinal beam 300, a second connection hole 321 is arranged on the second plate 32, and the fastener penetrates through the second connection hole 321 and any one of the first connection holes 301 to realize the position adjustment of the entire battery adapter device 100 in the length direction of the vehicle end longitudinal beam 300. The fastener is preferably a bolt.

[0079] More specifically, a plurality of first connection holes 301 arranged in a rectangular array are provided on the car body longitudinal beam 300. The plurality of first connection holes 301 are structures originally existing on the car body longitudinal beam 300 and are used for installing various components. The first connection holes 301 arranged in a rectangular array are relatively convenient to process. A plurality of second connection holes 321 arranged in a rectangular array are provided on the second plate 32. Correspondingly, the number of fasteners corresponds to the number of the second connection holes 321. Each second connection hole 321 is penetrated by a fastener, and the fastener penetrates through the corresponding first connection hole 301 and is connected to a nut. By providing the plurality of second connection holes 321 arranged in a rectangular array, the connection strength between the adapter mounting member 3 and the car body longitudinal beam 300 can be ensured.

[0080] Referring to Figure 15 , at least one third connection hole 311 for connecting with the vehicle body mounting beam 2 is provided on the first plate 31. Pass a screw through the third connection hole 311 and threadedly screw it onto the vehicle body mounting beam 2, and the fixation between the adapter mounting member 3 and the vehicle body mounting beam 2 can be realized.

[0081] As Figures 9 to 12 shown, the present embodiment further provides a power battery 200, including a lower box body 201, and an end upper box cover 202 and a middle upper box cover 203 that are buckled with the lower box body 201. Referring to Figure 9 and Figure 10 , a plurality of first bearing beams 2011 are arranged on the lower box body 201 along the circumferential direction. Referring to Figure 11 , a second bearing beam 2012 is arranged in the middle of the lower box body 201.

[0082] Specifically, referring to Figure 9 and Figure 11 , the lower box body 201 is in a cuboid shape. A total of four first bearing beams 2011 are arranged along the circumferential direction of the lower box body 201. A plurality of battery end locking assemblies 401 are arranged on each first bearing beam 2011 along its length direction. Correspondingly, a corresponding number of adapter end locking assemblies 402 are also arranged on the four frame beams 111. The battery end locking assemblies 401 on the first bearing beam 2011 are screwed to the adapter end locking assemblies 402 on the frame beam 111 one by one. As Figure 11As shown in the figure, two second bearing beams 2012 are arranged at intervals in the middle of the lower box body 201. A gap is defined between the two second bearing beams 2012, and this gap is isolated from the chambers on both sides for installing battery modules. The battery end locking assembly 401 is arranged on the two second bearing beams 2012, and two are arranged along the length direction of the second bearing beam 2012. One transfer end locking assembly 402 is arranged on each of the two inner installation beams 13, and the battery end locking assemblies 401 on the second bearing beam 2012 are screwed to the transfer end locking assemblies 402 on the inner installation beams 13 in a one-to-one correspondence.

[0083] As Figure 12 shown in the figure, two through holes 2013 are arranged at the bottom of the lower box body 201. The positions of the two through holes 2013 are aligned with the gap between the two second bearing beams 2012 and are communicated with this gap. The gun head of the unlocking and locking gun can pass through the through hole 2013 and act on the battery end locking assembly 401 on the second bearing beam 2012 to screw the locking bolt 4011 onto the corresponding locking nut 4021.

[0084] The number of the locking mechanisms 400 can be selected according to factors such as the weight of the power battery 200 and the diameter of the locking bolt 4011, and can bear the gravity load of the power battery 200 and the dynamic load during vehicle driving.

[0085] This embodiment also provides a vehicle, including a power battery 200, a vehicle-end longitudinal beam 300, and the battery adapter device 100 as described above. This vehicle can meet the requirements of being converted into a battery-swapping type vehicle without changing its original structure, without making major modifications to the vehicle production line, and reducing the R & D and production costs.
