Battery box

Abstract

The invention relates to a battery box, comprising a box body and a socket connector arranged on the surface of the box body and used for transmitting electrical signals to the outside, wherein the surface of the box body is provided with a groove, the socket connector is arranged on the wall of the groove and has a bottom end close to the groove wall and a top end far away from the groove wall, and the top end of the socket connector is lower than the surface of the box body located at the periphery of the groove. During collision of the battery box with an outer object, the socket connector is hardly damaged, so replacing frequency of the socket connector is lowered down, work efficiency is improved, and cost is reduced; meanwhile, when a pin connector is used for plug-in electric connection with the socket connector, the distance between the pin connector and the surface of the box body and the distance that the bending radius of a signal line extends to the surface of the box body are reduced, so occupation of effective space out of the battery box is reduced.

Description

technical field [0001] The invention relates to a battery box. Background technique [0002] Lithium-ion batteries are widely used in portable communication, vehicle power and grid energy storage due to their advantages of high voltage, large capacity, small size, light weight and wide operating temperature range, especially in the field of electric vehicles. [0003] The structure of the lithium-ion battery box used on the existing electric vehicle is like the battery box structure disclosed in the Chinese patent application "A Power Lithium Battery Box" with the publication number CN 103000845A. The box body, the box body includes a top cover, a bottom plate and a side wall between the top cover and the bottom plate, and a socket connector for communicating with the user is arranged on the surface of the box body, and the end of the socket connector is far away from the surface of the box body It protrudes from the surface of the box where it is located, so it is possible...

Problems solved by technology

[0003] The structure of the lithium-ion battery box used on the existing electric vehicle is as the battery box structure disclosed in the Chinese patent application "A Power Lithium Battery Box" with the publication number CN 103000845A. Box body, the box body includes a top cover, a bottom plate and a side wall between the top cover and the bottom plate, a socket connector for communicating with the user is arranged on the surface of the box body, and the end of the socket connector is far away from the surface of the box body It protrudes from the surface of the box where it is located, so it is possible to collide with foreign objects during the moving of the battery box and damage the socket connector, and when the socket connector is connected to the plug connector that matches it for communication, the plug The connector will extend outside the box. This structure will not only occupy the effective space outside the battery box, but also easily collide with other structures outside the box. After the collision, the plug connector and socket connector may be damaged. It affects the normal transmission of signals, and even needs to replace the socket connector or plug connector, which increases the workload and affects the installation efficiency of the battery line
