Problems solved by technology

[0003] The current battery pack waterproof device mostly adopts a single-stage sealing form with a rectangular cross-section. Due to the large overall size of the battery pack, the sealing surface of the box and the box cover will inevitably have a large warping deformation, so a single-stage rectangular cross-section is used. The waterproof device of the rubber strip cannot effectively prevent the water sprayed during car washing and the rainwater rolled up by the wheels when the vehicle is running.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] As shown in the figure, a new type of waterproof device for a battery pack for electric vehicles includes a case cover 1 , a rubber seal 2 , bolts 3 and a battery pack case 4 . The case cover 1 and the battery pack case 4 are fixed by bolts 3 . The rubber seal 2 is arranged between the battery pack case 4 and the case cover 1 to play a sealing role. The rubber seal 2 includes a rubber sealing body and a U-shaped frame 202 arranged in the rubber sealing body. The rubber seal 2 includes a first side seal portion 203 , a second side seal portion 204 , a third side seal portion 205 and a fourth seal portion 201 . The first side sealing part 203 , the second side sealing part 204 , the third side sealing part 205 and the fourth sealing part 201 are integrally formed. Wherein the first side sealing part 203 is arranged between the U-shaped skeleton 202 and the inne...

Abstract

A novel waterproof device for a battery pack used in an electric vehicle belongs to the technical field of battery pack structures. It includes a battery pack case, a case cover and a rubber seal. The rubber seal includes a rubber seal and a U-shaped skeleton arranged in the rubber seal. The rubber seal includes a U-shaped skeleton and a case cover. The fourth sealing part between the top surfaces, the first side sealing part arranged between the U-shaped skeleton and the inner side of the box cover, the second side sealing part arranged between the U-shaped skeleton and the outer side of the battery pack case, and The third side sealing part is arranged between the U-shaped framework and the inner side of the battery pack case. The battery pack waterproof device of the present invention is indeed an original structure, and can effectively prevent the water sprayed during car washing and the rainwater rolled up by the wheels from intruding into the battery pack when the vehicle is running, and has excellent sealing performance.

Description

technical field [0001] The invention belongs to the technical field of battery pack structures, and in particular relates to a new type of waterproof device for battery packs used in electric vehicles. Background technique [0002] The battery pack is the power source of electric vehicles, and it contains multiple battery packs, BSM controllers, relays, shunts, fuses, connecting copper bars and wires, etc. It is obvious: (1) In addition to the battery, there are live components in the battery pack; once water enters, it will happen: electrical short circuit, component damage, and even battery explosion and fire, causing serious accidents of car crashes and deaths. (2) Effectively solving the problem of water entering the battery pack is a key issue that needs to be solved urgently. [0003] The current battery pack waterproof device mostly adopts a single-stage sealing form with a rectangular cross-section. Due to the large overall size of the battery pack, the sealing surf...
