[0046] See Figures 1 to Figure 8As shown, an embodiment of the present application provides a battery system offline charging detection bracket, comprising a frame 1, a charging socket 2 and a cable. The frame 1 is provided with a wheel 14, and the frame 1 has a wire harness storage cavity. The charging socket 2 is provided on the frame 1, and the charging socket 2 is used to connect a charging gun. One end of the cable is connected to the charging socket 2, and the other end of the cable is provided with a quick-plug connector, and the quick-plug connector is used to connect a battery system (such as a high-voltage box of a battery system), and the cable can be accommodated in the wire harness storage cavity. When the battery system offline charging detection bracket of the present application is used, the charging gun of the charging pile is plugged into the charging socket 2, the cable is taken out of the wire harness storage cavity, and the quick-plug connector is plugged into the battery pack to realize the detection of the functional performance of the charging status of the battery pack. The battery system offline charging detection bracket of the present application can realize the connection between the charging gun and the battery pack when the battery system does not have a charging interface. It can enable the battery pack to perform functional detection of the charging status at the battery pack production line or the battery pack storage place, so that the battery system can be tested in a timely and convenient manner when it is offline, greatly reducing the manpower, material resources and time required for detection.

[0047] The cables used when transferring battery packs are long and heavy. The battery system offline charging detection bracket of the present application is provided with a wire harness storage cavity. When not in operation, the cables are centrally placed in the wire harness storage cavity of the frame 1, making it more convenient to carry the cables, reducing the burden on the staff, improving work efficiency, and ensuring that the cables are placed in order, making them less likely to be damaged. Wheels 14 are provided at the bottom of the frame 1, and easy transfer can be achieved by pushing the frame 1, making the movement of the battery system offline charging detection bracket more labor-saving during use. A quick-plug connector is provided at the end of the cable, a high-voltage box is provided on the battery pack, and a quick-plug interface is provided on the high-voltage box. The quick-plug connector can be directly plugged into the quick-plug interface and connected through a quick-plug structure. There is no need for professionals to use professional tools, making the installation process more convenient and quick.

[0048] In some possible implementations, the vehicle frame 1 includes a base frame 13 and a first longitudinal frame 11 and a second longitudinal frame 12 disposed on either side of the base frame 13. The wheels 14 are connected to the base frame 13, and a wiring harness storage compartment 15 is formed on the base frame 13. The first longitudinal frame 11 and the second longitudinal frame 12 are the main skeletons of the entire vehicle frame 1. The four corners of the base frame 13 are respectively connected to the two first longitudinal frames 11 and the two second longitudinal frames 12, ensuring a stable connection of the base frame 13 and ensuring the load-bearing capacity of the base frame 13, so that it can stably carry cables of greater weight. The wiring harness storage compartment 15 is disposed on the base frame 13 at a lower height, so that more space can be reserved above for the installation of other structures.

[0049] In some possible implementations, an integrated box 3 is mounted on the first longitudinal frame 11. The integrated box 3 comprises a box body 31 and a cover 32. The box body 31 is connected to the first longitudinal frame 11, and the charging socket 2 is housed within the box body 31. The cover 32 is hingedly connected to the box body 31 and is used to open and close the box body 31. The integrated box 3 integrates the charging socket 2 within the box body 31 and is provided with the cover 32, allowing the integrated box 3 to completely enclose the charging socket 2, protecting it from water, dust, and other debris.

[0050] Furthermore, the cover 32 and the box body 31 are rotatably connected. When the cover 32 needs to be opened to expose the charging socket 2, it is only necessary to rotate the cover 32, which is easy to operate.

[0051] Furthermore, a first clamping portion 35 is provided on the cover 32, and a second clamping portion is provided on the box body 31. The first clamping portion 35 and the second clamping portion can be engaged or disengaged by pressing, and the pressing method makes the operation simpler and faster.

[0052] In some possible implementations, a first hinged seat 33 is provided on the side of the box body 31 closest to the wheel 14, and a second hinged seat 34 is provided on the cover body 32. The first hinged seat 33 and the second hinged seat 34 are hingedly connected. The side of the box body 31 closest to the wheel 14 is the lower side of the box body 31. The hinged connection point of the cover body 32 and the box body 31 is located on the lower side. When the cover body 32 is opened, it naturally droops downward due to its own gravity. There is no need to support the cover body 32 manually or to set a limit structure on the cover body 32. The cover body 32 does not hinder the connection between the charging cable and the charging socket 2, nor does it compress the charging cable.

[0053] In some possible implementation schemes, a storage space is formed between the first longitudinal frame 11 and the second longitudinal frame 12, and the storage space is connected to the wiring harness storage cavity. The charging socket 2 has a terminal 21 extending to the storage space. The terminal 21 is electrically connected to the cable. The storage space provides a storage position for the terminal 21, and also provides sufficient space for the connection between the terminal 21 and the cable. The terminal 21 is fixedly connected to the cable, and the terminal 21 and the cable can be connected by bolts, welding, riveting, etc. Preferably, the terminal 21 and the cable are connected by bolts, which does not require professionals to use professional tools. Not only is the connection stable, but the installation and disassembly are also simpler and faster, which is convenient for later maintenance.

[0054] In some possible implementations, baffles 17 are provided along the sides of the base frame 13. Together, these baffles 17 and the base frame 13 form the wiring harness storage cavity. Baffles 17 are attached to the side of the base frame 13 facing away from the wheels 14, and are provided between each adjacent first longitudinal frame 11 and second longitudinal frame 12. Each baffle 17 and the base frame 13 enclose a storage cavity with an upper opening, preventing cables contained within the wiring harness storage cavity from sliding outward.

[0055] Furthermore, the baffle 17 is provided with a through hole, which can reduce the weight of the baffle 17. The hole can be circular or strip-shaped, and preferably the through hole is a strip-shaped hole. Dust entering the wiring harness storage cavity can be discharged through the strip-shaped hole, and dust accumulation will not occur, so the wiring harness storage cavity can be kept clean and tidy.

[0056] In some possible implementations, the battery system offline charging and testing support includes an upper platform 16. The upper platform 16 is located on top of the base frame 13 and is connected to the first longitudinal frame 11 and the second longitudinal frame 12. The upper platform 16 can be used to carry equipment for testing battery system cell voltage, cell temperature, and other parameters. These devices can be placed together on the tooling equipment platform, achieving integrated testing equipment and facilitating the testing process.

[0057] In some possible implementations, the cable is fixed to the upper platform 16. After the cable is electrically connected to the charging socket 2, it is fixed below the upper platform 16 to prevent the cable from twisting during use, which may cause damage to the cable or the connection point between the cable and the charging socket 2. This can extend the service life of the cable and the maintenance period of the connection point between the cable and the charging socket 2.

[0058] In some possible implementations, a wire harness securing bracket 4 is provided on the side of the upper platform 16 facing the base frame 13. A wire binder is provided on the wire harness securing bracket 4. The cable is secured to the wire binder. The wire binder can wrap around the crossbeam 41 and the cable, securing the crossbeam 41 and the cable together. This further enhances the secure connection between the cable and the upper platform 16, reducing the likelihood of pulling and twisting at the connection point between the cable and the charging socket 2, thereby further extending the cable's service life and the maintenance cycle at the connection point between the cable and the charging socket 2.

[0059] Furthermore, the wire harness fixing bracket 4 is provided with a cross beam 41 and bending plates 42 located at both ends of the cross beam 41. The bending plates 42 are bent toward the upper platform 16. The cables pass through the gap between the cross beam 41 and the upper platform 16 and overlap on the cross beam 41. The bending plates 42 can prevent the cables from falling from the side ends of the cross beam 41.

[0060] Furthermore, a plurality of cable holders are provided on the crossbeam 41. Since there are a plurality of cables, each cable can be connected more firmly using a cable holder. The cable holders can be cable racks, cable ties, Velcro straps, etc.

[0061] In some possible embodiments, the second longitudinal frame 12 extends out of the upper platform 16, and a handle 5 is provided on the top of the second longitudinal frame 12. The handle 5 provides a gripping position for the user, making the process of pushing the frame 1 more labor-saving, improving user comfort, and thus improving work efficiency.

[0062] Furthermore, the battery system offline charging detection bracket includes four wheels 14, which are respectively arranged at the bottom ends of the two first longitudinal brackets and the two second longitudinal brackets. Among them, the wheels 14 are universal wheels 14, and a locking device is provided on the wheels 14. When unlocked, the wheels 14 can rotate at will, which facilitates pushing the frame 1 to the specified position. When in the locked state, the wheels 14 cannot rotate and the frame 1 cannot move. In this way, when the charging socket 2 and the battery pack are connected for energy replenishment, it plays a certain limiting role on the frame 1, ensuring that the frame 1 will not move at will, and the lock is simple and convenient to operate when opening or closing, and no other professional fixing tools are required.

[0063] In some possible implementations, the battery system offline charging and testing bracket includes two charging sockets 2, each of which is connected to a cable. The two charging sockets 2 can increase the charging power and enable faster charging and testing for large-capacity batteries.

[0064] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
