Description

Technical Field

[0001] This utility model relates to the field of battery box technology, specifically a waterproof battery box structure. Background Technology

[0002] With the development of the power battery industry, customers are placing higher demands on the maintenance and repair of battery boxes.

[0003] Most common battery boxes currently have a single-cover design, which requires all the bolts on the cover to be removed during maintenance, seriously affecting the efficiency of maintenance. However, the existing double-cover design cannot guarantee the IP rating of the box, affecting the waterproof performance of the battery box. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a waterproof battery box structure that can be maintained without removing all the bolts on the box cover during maintenance, thereby improving maintenance efficiency. At the same time, it also has the function of preventing water seepage inside the box, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof battery box structure, including a box body, with C-shaped connecting frames symmetrically arranged on the upper surface of the box body. The connecting frames are integrally connected to the box body. A crossbeam is provided between the open ends of the two connecting frames. The crossbeam and the two connecting frames form two square frames for mounting box covers. Threaded holes for connecting box covers are evenly distributed on the crossbeam and the connecting frames. The upper surfaces of the crossbeam and the connecting frames are covered with foamed silicone. A drainage groove is provided in the middle of the crossbeam, and the drainage groove is opened along the length direction of the crossbeam.

[0006] As a preferred technical solution of this utility model, the threaded holes on the crossbeam are symmetrically arranged along its length, and the two rows of threaded holes on the crossbeam and the threaded holes on the connecting frame respectively form a square threaded hole group corresponding to the hole position on the box cover to be installed.

[0007] In a preferred embodiment of this invention, the crossbeam and the connecting frame are connected by welding.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: The waterproof battery box structure has two connecting frames at the top of the original box body, and a crossbeam is set between the two connecting frames. The threaded holes on the connecting frames and the crossbeam form two sets of threaded holes for the installation of the box cover. During maintenance, only one box cover needs to be removed, without having to remove all the box covers, which greatly improves maintenance efficiency. At the same time, foamed silicone is set on the connecting frames and the crossbeam to form a seal when the box cover is installed, which can effectively prevent rainwater from entering the box body and improve the safety of the battery box.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 1 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0012] Please see Figure 1 This utility model provides a technical solution: a waterproof battery box structure, including a box body 1. C-shaped connecting frames 2 are symmetrically arranged on the upper surface of the box body 1. The connecting frames 2 are integrally connected to the box body 1. The open ends of the two connecting frames 2 are arranged opposite each other but not connected. A crossbeam 3 is arranged between the open ends of the two connecting frames 2. The crossbeam 3 and the two connecting frames 2 form two square frames for installing box covers. The crossbeam 3 and the connecting frames 2 are evenly distributed with threaded holes 4 for connecting the box covers. The box covers are connected to the crossbeam 3 and the connecting frames 2 by bolts. The upper surfaces of the crossbeam 3 and the connecting frames 2 are covered with foamed silicone, which plays a role in sealing and waterproofing when the box covers are installed.

[0013] Furthermore, to facilitate the installation of the box cover, the threaded holes 4 on the crossbeam 3 are symmetrically arranged along its length. The two rows of threaded holes 4 on the crossbeam 3 and the threaded holes 4 on the connecting frame 2 respectively form a square threaded hole group corresponding to the hole position on the box cover to be installed.

[0014] To prevent water accumulation on the crossbeam 3 and increase the risk of water seepage inside the box 1, a drainage channel 5 is provided in the middle of the crossbeam 3. The drainage channel 5 is opened along the length of the crossbeam 3, and the gap between the drainage channel 5 and the two C-shaped connecting brackets 2 on the box 1 is on the same straight line. The accumulated rainwater will be discharged through the drainage channel 5.

[0015] To enhance the connection between the crossbeam 3 and the connecting frame 2, the crossbeam 3 and the connecting frame 2 are connected by welding.

[0016] When in use: Install the two covers on the connecting frame 2 and the crossbeam 3 respectively, and fix them with bolts; during maintenance, as needed to inspect the location of the battery box, simply remove the bolts on the cover at the corresponding location, which greatly improves maintenance efficiency.

[0017] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model. The scope of the utility model is defined by the appended claims and their equivalents.
