Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery energy storage, in particular to a waterproof structure for an energy storage battery box. Background Art

[0002] For the waterproofing of the box, most of them use silicone or rubber rings filled in the connection position of the shell, and the extruded foam is fixed by screws on the front or side. The foam is filled in the gap between the shells to achieve the purpose of waterproofing. Most of the shells can be easily assembled and connected with the upper and lower covers when they are lying flat. When encountering a standing energy storage box, it is not convenient to operate whether the extruded foam is fixed on the front or side. For the waterproofing of the outlet, most of them use cable sleeves and waterproof wire sleeves, which cannot be used for cable specifications of different models. Once the terminal of the connection is larger than the inner diameter of the waterproof connector, it cannot be installed. There are also methods of directly pouring glue at the outlet for waterproofing, which is easy to overflow and inconvenient to handle. The glue application is one-time and difficult to repair after sales.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0026] See also Figures 1 to 9 A waterproof structure for an energy storage battery box is shown, comprising a battery box 1, wherein the battery box 1 comprises a front door panel assembly 10, a rear shell assembly 20 movably matched with the front door panel assembly 10, and a cable outlet cover 30 arranged on the battery box 1 and matched with a cable 2 arranged on the battery box 1.

[0027] The front door panel assembly 10 is provided with a first waterproof structure 40 that cooperates with the rear shell assembly 20, the battery box 1 is provided with a second waterproof mechanism 50 that cooperates with the cable 2, and the outlet cover plate 30 is provided with a third waterproof structure (not shown in the figure) that cooperates with the second waterproof structure 50.

[0028] The front door panel assembly 10 includes a front door panel 11 movably disposed on the rear shell assembly 20 and a front door panel pipe position hole 12 disposed on the front door panel 11 and matched with the rear shell assembly 20. The rear shell assembly 20 in this embodiment includes a rear shell 21 matched with the front door panel 11 and a rear shell pipe position pin 22 disposed on the rear shell 21 and used to pass through the front door panel pipe position hole 12. Specifically, the front door panel 11 is assembled to the rear shell 21 in the direction of the arrow. During the assembly process, the front door panel pipe position hole 12 is buckled into the rear shell pipe position pin 22, and then buckled into the rear shell assembly 20 along the direction of the arrow to complete the assembly.

[0029] The first waterproof structure 40 includes a foam foam 41 disposed on the front door panel 11, one side of the foam foam 41 is fixed to the inner wall of the front door panel 11, and the other side of the foam foam 41 is the front cover waterproof surface a in contact with the rear shell 21. The waterproof part of the first waterproof structure 40 in this embodiment is mainly the interference and compression waterproofing of the flange of the rear cover assembly 20 and the foam foam 41 of the front door panel 11.

[0030] The second waterproof structure 50 includes a cable waterproof rubber block 51 disposed on the battery box 1 and matched with the cable 2, and a waterproof sawtooth ring structure 52 is disposed on the cable waterproof rubber block 51 to adapt to cables 2 of different thicknesses. The waterproof sawtooth ring structure 52 in this embodiment includes a waterproof rubber seat 53 sleeved on the cable 2 and a waterproof sawtooth small circle 52a, a waterproof sawtooth middle circle 52b, and a waterproof sawtooth large circle 52c disposed at intervals on the waterproof rubber seat 53.

The outlet cover plate 30 in this embodiment is connected to the battery case 1 by a fixing bolt 30a. Specifically, after the cable 2 is fixed to the connector of the battery case 1, the cable 2 is pressed onto the cable waterproof rubber block 51, and the outlet cover plate 30 is covered (the outlet cover plate 30 is also assembled with a waterproof rubber block), the cable waterproof rubber block 51 of the battery case 1 and the waterproof rubber block of the outlet cover plate 30 are buckled to form a waterproof function, and the fixing screw 30a is locked to complete the assembly.

[0032] The installation process of the utility model is as follows:

[0033] Assemble the front door panel 11 to the rear shell 21 in the direction of the arrow. During the assembly process, the front door panel tube hole 12 is buckled into the rear shell tube pin 22, and then the rear shell assembly 20 is buckled in the direction of the arrow to complete the assembly; then, after fixing the cable 2 to the connector of the battery box 1, press the cable 2 onto the cable waterproof rubber block 51, cover the outlet cover 30 (the outlet cover 30 is also assembled with a waterproof rubber block), the cable waterproof rubber block 51 of the battery box 1 and the waterproof rubber block of the outlet cover 30 are buckled to form a waterproof function, and the fixing screws 30a are locked to complete the assembly; finally, the principle that the cable waterproof rubber block 51 can adapt to different cable thicknesses is that there are waterproof serrated ring structures 52 with different gears in the cable waterproof rubber block to adapt to different cable thicknesses. When the outlet cover 30 is assembled, the cable waterproof rubber block 51 on the battery box 1 and the waterproof rubber block on the outlet cover 30 are buckled together to form a waterproof ring. The utility model uses three waterproof structures to achieve that the waterproof surface of the front door plate 11 and the rear shell 21 is the front cover waterproof surface a, the waterproof surface of the cable 2 outlet is the outlet waterproof surface b, and the waterproof surface of the outlet cover 30 and the rear shell assembly 20 is the outlet cover waterproof surface c.
