[0041] See also Figures 1 to 9 , an embodiment of the present application provides a battery rack, comprising:

[0042] A main frame 1, wherein the main frame 1 has a multi-layer support frame 101 arranged in an up-down direction, the support frame 101 is used to support and place the power battery 4, and the support frame 101 is provided with an entrance and exit along a first horizontal direction;

[0043] A roller group 2, the roller group 2 is installed in parallel in the middle area of ​​the support frame 101, and includes at least one electric roller 201, and the length direction of the electric roller 201 is perpendicular to the first horizontal direction;

[0044] The charging device 3 is fixedly mounted on the support frame 101 and arranged adjacent to the entrance and exit. The charging device 3 includes: a mounting base 301 and a charging unit 302 and a driving unit 303 arranged on the mounting base 301, wherein the charging unit 302 is connected to the driving unit 303, and the driving unit 303 is used to drive the charging unit 302 to move along a second horizontal direction to insert or remove the charging port of the power battery 4, and the second horizontal direction is perpendicular to the first horizontal direction.

[0045] The battery rack provided in this embodiment includes: a main frame 1, a roller group and a charging device 3, wherein the main frame 1 has a multi-layer support frame 101 arranged in the up-down direction, wherein the support frame 101 is used to provide an installation base for the roller group 2 and the charging device 3, and to provide support for the placement of the power battery 4. Specifically, the support frame 101 is provided with a plurality of support frames 101 arranged in the first horizontal direction (such as Figure 1 An entrance and exit (as shown in A) is provided to facilitate the placement and removal of the power battery 4. Based on the installation position of the battery rack, the entrance and exit may be at least one of the two sides of the support plate along the first horizontal direction.

[0046] The rollers in the roller group 2 are arranged in parallel along a first horizontal direction and installed in the middle area of ​​the support frame 101 so as to provide support, buffering and drive for the movement of the power battery 4 on the support frame 101 through the roller group 2. The roller group 2 includes at least one electric roller 201 for driving. A driving motor and a reducer are arranged inside the electric roller 201 so that the electric roller 201 can rotate on its own. The electric roller 201 is used for driving. Compared with the existing method of setting a dedicated driving device for the roller group on the main frame 1 or near the main frame 1, it is beneficial to reduce the occupation of the space of the battery swap station by the dedicated driving device, thereby helping to improve the utilization rate of the space of the battery swap station, and at the same time helping to save costs and reduce the difficulty of installation.

[0047] The charging device 3 includes a mounting base 301, a charging unit 302 and a driving unit 303. The mounting base 301 is fixedly mounted on the support frame 101 and provides a mounting base for the charging unit 302 and the charging unit 302; the driving unit 303 is connected to the charging unit 302 and can drive the charging unit 302 to move in a second horizontal direction (such as Figure 1 B in the figure) to insert or pull out the charging port of the power battery 4. For example: when the power battery 4 needs to be charged, the driving unit 303 drives the charging unit 302 to move toward the power battery 4 along the second horizontal direction and insert it for charging. At this time, the power battery 4 can be charged by the charging unit 302; when the power battery 4 is fully charged, the driving unit 303 can drive the charging unit 302 to move away from the power battery 4 in the second horizontal direction, so that the charging unit 302 pulls out the charging port of the power battery 4, disconnects the power battery 4 from the charging unit 302, stops charging the power battery 4, and facilitates the removal of the power battery 4.

[0048] In addition, preferably, the charging device 3 is arranged adjacent to the entrance and exit rather than opposite to the entrance and exit, so as to avoid damage to the power battery 4 and / or the charging device 3 caused by collision between the power battery 4 and the charging device 3 due to errors in the roller group 2 during the process of conveying the power battery 4.

[0049] To summarize, the battery rack provided in the present application conveys the power battery 4 by providing a roller group 2 with an electric roller 201, and charges or stops charging the power battery 4 by plugging and unplugging a charging device 3 that is arranged in a direction different from the movement direction of the power battery 4. This is beneficial to reducing the occupation of the space of the battery swap station by dedicated driving equipment, thereby helping to improve the utilization rate of the space of the battery swap station, and at the same time helping to save costs, reduce installation difficulty, and improve the safety of the power battery 4 and / or charging device 3 in the battery rack.

The driven roller is connected to a motorized roller 201 through a gear or a chain, and rotates synchronously with the motorized roller 201 to transport the power battery 4. In this embodiment, by providing unpowered rollers and / or driven rollers, the number of motorized rollers can be reduced accordingly, which is beneficial to cost saving. When the combination of the motorized roller 201 and the unpowered roller is preferably adopted, since there is no direct connection between the rollers, the difficulty of installing the roller group 2 can also be reduced.
