Description

Technical Field

[0001] The utility model relates to the technical field of rubber coating, in particular to an anti-tracking battery rubber coating seal. Background Art

[0002] With the popularization of electronic products such as electric vehicles and smart phones, the safety issues of batteries, as their core components, are becoming increasingly prominent.

[0003] Existing sealing plates often use a single flat plate and are fixed with screws. After the sealing plate is closed, it can only work on a single bonding surface, which cannot increase the adhesive area of ​​the glue to achieve a better bonding effect. In addition, the existing sealing plate cannot play a certain role in relieving the flatulence inside the battery pack.

[0004] In view of this, the inventors specially designed an anti-tracking battery encapsulation seal, which resulted in this case. Utility Model Content

[0005] The purpose of the utility model is to provide a battery pack sealant with anti-tracking properties, which can effectively increase the area for glue adhesion and alleviate flatulence inside the battery pack.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The battery pack seal is provided with a cover body, a buffer plug and a locking cover; the outer edge of the cover body is provided with a hanging edge on the circumference, which is used to hang the seal on the battery shell and vertically adhere the excess glue to the outer side of the battery shell; the cover body inside the hanging edge is provided with a plurality of fixing holes on the circumference, and the fixing holes are locked to the battery shell by screws; the lower end of the cover body inside the fixing hole is provided with an annular ridge, which is used to vertically adhere the excess glue to the inner side of the battery shell; a buffer channel is provided in the middle of the cover body; the buffer plug is provided on the buffer channel; the locking cover is provided at the upper end of the buffer plug and is threadedly connected to the cover body; a groove is provided at the upper end of the locking cover; a tightening block is provided in the groove; a buffer hole is provided at the upper end of the cover body outside the buffer channel; the lower end of the buffer hole is connected to the buffer channel, and the buffer hole is used to relieve excessive flatulence inside the battery pack.

[0008] Furthermore, the hanging edge includes a fixed block and a hook; the upper end of the fixed block is fixedly connected to the lower end of the outer edge of the cover body; the hook is arranged at the lower end of the fixed block close to the middle side of the cover body.

[0009] Furthermore, the cross section of the hook is a right triangle, and the hypotenuse of the hook is inclined from the bottom of the hook to one side of the fixing hole.

[0010] Furthermore, the hanging edge is made of elastic material.

[0011] Furthermore, the lower opening of the buffer channel is smaller than the upper opening; and the buffer plug is arranged on the transverse portion in the buffer channel.

[0012] Furthermore, the buffer hole is communicated with a side wall of the buffer plug at the upper portion of the buffer channel.

[0013] Furthermore, the upper ends of the tightening block and the locking cover are on the same horizontal plane as the upper end of the cover plate body.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects:

[0015] 1. The utility model provides a hanging edge on the outer edge of the cover body and an annular convex edge on the inner circumference of the lower end of the cover body, so that the glue can be vertically adhered to the inside and outside of the battery shell, increasing the adhesion area, thereby improving the sealing and anti-tracking performance.

[0016] 2. The utility model opens a buffer channel in the middle of the cover plate body and provides a buffer hole on the cover plate body outside the buffer channel. When the internal air pressure of the battery pack is too high, the internal air pressure of the battery pack squeezes the lower end of the buffer plug, and the locking cover squeezes the upper end of the buffer plug, so that the upper end of the buffer plug remains in position while the lower end of the buffer plug is deformed. The gas flows through the gap between the buffer plug and the buffer channel and is finally discharged through the buffer hole. The exhaust process is that the internal air pressure is much greater than the external air pressure, and the gas flows from the inside of the battery pack to the outside; when the internal air pressure of the battery pack drops to a certain level, the buffer plug, under the action of the locking cover, blocks the end of the buffer hole, so that the gap between the buffer plug and the buffer channel is sealed, and continues to maintain good sealing, so that outside air is not easy to enter the battery pack, thereby solving the problem of reduced battery service life due to the entry of outside air, effectively alleviating the gas pressure generated by temperature changes or chemical reactions inside the battery pack, and avoiding safety hazards caused by excessive internal pressure.

[0017] 3. The design of the hanging edge of this utility model adopts the form of a fixing block and hook. The cross section of the hook is a right triangle, and the hypotenuse extends from the bottom of the hook to the fixing hole. This design not only facilitates installation but also ensures a good sealing effect. The hanging edge is made of elastic material, which can adapt to the battery shell within the tolerance range of different production processes, enhancing applicability.
