Description

Technical Field

[0001] This utility model relates to an automotive battery box, specifically a high-sealing battery box for new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels with new on-board power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. The power source of new energy vehicles is a battery pack, which is stored in a battery box, and the top of the battery box is protected by a box cover.

[0003] Existing battery box covers are typically connected to the battery box using a large number of bolts, making disassembly cumbersome and reducing maintenance efficiency when inspecting the batteries inside; moreover, the sealing of the battery box cannot be guaranteed.

[0004] Therefore, we propose a highly sealed battery box for new energy vehicles. Utility Model Content

[0005] The main objective of this disclosure is to provide a highly sealed battery box for new energy vehicles, so as to effectively solve the problems raised by the inventors in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-sealing battery box for new energy vehicles includes a battery box housing and a battery module. The front and rear inner walls of the battery box housing are inlaid with rubber and plastic sealing strips. The battery module is installed inside the battery box housing, and the outer side of the battery box housing is tightly attached to the rubber and plastic sealing strips. A buffer pressure reduction component is provided inside the battery box housing. A sealing cover is detachably installed on the top surface of the battery box housing, and a secondary sealing component is provided on the sealing cover.

[0008] Preferably, the secondary sealing assembly includes a magnetic sheet and an alignment magnetic layer. The magnetic sheet is fixedly installed on the outer edge of the sealing cover, and the thickness of the magnetic sheet decreases from top to bottom. The alignment magnetic layer is fixedly connected to the upper end of the outer side of the battery box housing, and the magnetic sheet and the alignment magnetic layer are magnetically attracted to each other, that is, the magnetic sheet seals the connection between the battery box housing and the sealing cover.

[0009] Preferably, the buffer pressure relief assembly includes a buffer spring and an anti-collision spring. One end of the buffer spring is fixedly connected to the left inner wall of the battery box housing, and the other end abuts against the battery module. One end of the anti-collision spring is fixedly connected to the right inner wall of the battery box housing, and the other end contacts the battery module.

[0010] Preferably, a finned heat sink is fixedly installed inside the battery box housing, and one end of the finned heat sink penetrates through the side plate of the battery box housing.

[0011] Preferably, the side wall of the battery box housing is inlaid with a polygonal sleeve, the sealing cover has a threaded hole, and a fastening bolt is screwed into the threaded hole, the lower end of the fastening bolt being threaded into the polygonal sleeve.

[0012] Preferably, a number of wiring ports are fixedly installed on the side of the battery box housing.

[0013] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0014] (i) In this application, the battery module is installed inside the battery box housing. The rubber and plastic sealing strip can improve the sealing performance and increase the friction of the battery module. With the elastic restraint of the buffer spring and the anti-collision spring, a damping effect is formed, thereby improving the safety of the battery module. The fin-shaped heat sink can regulate the temperature inside the battery box housing so that the battery module is in a relatively stable temperature range.

[0015] (ii) In this application, the sealing cover is installed on the top surface of the battery box housing by means of a polygonal sleeve and fastening bolts, so that the battery box housing is sealed to protect the battery module. When the sealing cover is tightly attached to the top of the battery box housing, the magnetic sheet is just fitted on the upper edge of the battery box housing, and under the magnetic attraction of the matching magnetic layer, the magnetic sheet is tightly attached to the opening of the battery box housing to further improve the sealing performance of the battery box housing.
