Description

Technical Field

[0001] The utility model relates to the technical field of new energy batteries, in particular to a battery box sealing structure. Background Art

[0002] In recent years, due to the depletion of energy and the need for environmental protection, new energy vehicles have become the mainstream of market promotion. New energy, also known as unconventional energy, refers to various energy forms other than traditional energy. As a key component of electric vehicles, new energy batteries play a vital role. When new energy batteries are used in automobiles, they are sealed and installed in battery boxes.

[0003] At present, most of the box sealing methods on the market are to use single-component or two-component materials to cure on the upper cover and the lower box to form an elastomer as a sealing strip for sealing. However, the cross-sectional structure of the sealing strip used is relatively simple, and there are relatively few sealing contact points. Since the sealing effect is mainly reflected by the characteristics of the material itself rather than the structure, it is easy to cause poor sealing and affect the use. In view of this, a battery box sealing structure with relatively high requirements on the elasticity and sealing properties of the material is proposed to solve the above problems.

[0016] As a preferred technical solution of the utility model, the top surface of the lower box body is provided with a limiting member for limiting the distance between the upper cover body and the lower box body after the upper cover body and the lower box body are assembled.

[0017] The above technical solution is adopted to ensure the appropriate compression thickness of the sealing ring after the lower box body and the upper cover body are assembled.

[0018] As a preferred technical solution of the present utility model, the edges of the upper cover body are provided with edging, and the edging matches the lower box body.

[0019] The above technical solution is adopted to ensure that water vapor and the like will not enter through the overlap gap between the upper cover body and the lower box body.

[0021] The adoption of the technical solution can achieve an effective sealing effect.

[0022] As a preferred technical solution of the present utility model, the sealing ring is made of foamed silicone.

[0023] The above technical solution is adopted to ensure sealing and reliability.

[0024] As a preferred technical solution of the utility model, the sealing ring includes a first sealing strip, a second sealing strip, a third sealing strip and a fourth sealing strip, and the first sealing strip, the second sealing strip, the third sealing strip and the fourth sealing strip are spliced ​​end to end in sequence.

[0025] The above technical solution is adopted to improve flexibility and reduce production costs through the process of segmented splicing.

[0026] Compared with the prior art, the utility model has the following beneficial effects: the battery box sealing structure has flexible design, simple structure, safety and reliability, can ensure effective sealing effect, prevent the entry of moisture and dust, and ensure safe, stable and effective use;

[0027] 1. The fixing bolt passes through the circular through hole and is threadedly connected to the threaded hole to realize the stable and reliable assembly of the lower box body and the upper cover body;

[0028] 2. The edge of the lower box is designed to be bent inward, which can ensure that the edge of the lower box can be used for routing and placing other electrical components at the bend, which can effectively utilize the space. In addition, the inward bend makes it easier to highlight the unique shape of the battery pack;

[0029] 3. The setting of the limiter on the lower box body can limit the distance between the upper cover and the lower box body after the upper cover and the lower box body are assembled, so as to ensure that the sealing ring is in the most suitable compression thickness and ensure that the sealing ring can play the best performance;

[0030] 4. The edging that is conveniently arranged around the upper cover body can ensure that after the upper cover body and the lower box body are assembled, the edging wraps the lower box body, ensuring that water vapor and dust will not enter from the overlap gap between the upper cover body and the lower box body. In addition, during installation, the upper cover directly covers the lower box body, which plays a role in installation positioning;

[0031] 5. The sealing ring is made of foamed silicone material, which can ensure the sealing effect and reliability of use. At the same time, the sealing ring is spliced ​​by segmented splicing, which improves the flexibility of use and avoids the problem that the sealing ring is large in size and irregular in structure, which would cause the mold development cost and cost to be very expensive if a one-time molding process is adopted.
