Abstract
Description
Technical Field
[0001] This utility model relates to a battery box, specifically a battery box with a pull-out structure. Background Technology
[0002] Alkaline nickel-cadmium batteries require regular level checks and fluid replenishment. However, once installed in a vehicle, these procedures are inconvenient for routine maintenance and fluid level checks. Currently, battery boxes with a boom-type structure are complex, resulting in large lateral and longitudinal dimensions, which hinders miniaturization and weight reduction. Utility Model Content
[0003] This utility model provides a battery box with a pull-out structure, which solves the problems of inconvenient battery installation and electrolyte replenishment in practical applications. It also solves the problems of complex structure and large horizontal and vertical dimensions of the arm-type battery box.
[0004] This utility model is achieved through the following technical solution:
[0005] A battery box with a pull-out structure includes a box body and a slide rail trolley. The box body is equipped with bearings, and the slide rail trolley is equipped with C-shaped guide rails that can roll on the bearings, allowing the slide rail trolley to be pulled out from one side of the box body, and the battery is placed in the slide rail trolley.
[0006] Handles are provided on the end face of the sliding rail trolley.
[0007] The battery box has a two-sided door structure.
[0008] The sliding rail trolley structure of this utility model is simpler than the traditional arm-type battery box structure. It saves space by reducing the dimensions of the traditional arm-type battery box in the horizontal and vertical directions, which is more conducive to product miniaturization and weight reduction. Under the same battery arrangement, the sliding rail trolley structure can reduce the box size by about 15% and the box weight by about 20% compared with the traditional arm-type structure.

[0010] Figure 2 This is a single-sided pull-out diagram of the slide rail type trolley of this utility model;
[0011] Figure 3 This is a schematic diagram of the sliding rail trolley of this utility model. Detailed Implementation
[0012] like Figure 1-3As shown, this utility model is a battery box with a pull-out structure. The battery box adopts a two-side door structure and a sliding rail trolley structure. The box body is equipped with bearings, and the sliding rail trolley is equipped with C-shaped guide rails that can roll on the bearings, so that the trolley can pull out two sets of batteries to the sides respectively. After the batteries are pulled out to the side of the trolley, it is convenient for page inspection and maintenance.
[0013] This utility model battery box adopts a two-side door structure and a sliding rail trolley structure, which can accommodate two sets of batteries in a small space.
