High-voltage explosion-proof battery pack and manufacturing method of battery pack

Abstract

The invention relates to a high-voltage explosion-proof battery pack. The high-voltage explosion-proof battery pack comprises a battery box, a battery group and a cover body, wherein the battery group comprises at least two batteries; and the batteries are fixed inside the battery box in a mutual isolation manner. The explosion-proof battery pack also comprises a rigid circuit board, a flexible circuit board and an external connector, one end of the flexible circuit board is connected with the rigid circuit board, the other end of the flexible circuit board is connected with the battery group, and series connection of the batteries is realized; the rigid circuit board and the flexible circuit board are accommodated in the explosion-proof battery box respectively; the rigid circuit board is positioned at the position close to one side of the battery box; the external connector is connected with the rigid circuit board; the cover body also comprises a circular side wall, a through hole is formed in the side wall corresponding to the position of the external connector; the external connector passes through the through hole to be stretched outwards from the cover body; and the box body is assembled with the battery box together.

Description

technical field [0001] The invention relates to the field of explosion-proof electronic communication and all electronic products containing batteries, in particular to an explosion-proof battery pack which can provide high voltage and is applied to explosion-proof electronic communication products. Background technique [0002] At present, there are some special electronic products that require a large working voltage, and the voltage that a single battery can provide is limited, so it is often necessary to increase the voltage to work normally: for example, the power supply required by a notebook computer is 7.4 volts, such as the work of a battery electric car The voltage is usually 36 volts, etc., which are much higher than the voltage range that a single battery can provide; at the same time, it is difficult for a single battery to reach such a high voltage in the actual manufacturing process, so there are multiple batteries. In addition, the use safety of electronic pr...

Problems solved by technology

[0006] The present invention provides a high-voltage explosion-proof battery pack, which can solve the problems of time-consuming and low production efficiency in the explosion-proof battery pack in the prior art due to the glue on the entire surface of the battery cell; and improves the The operation of the batteries is difficult due to the limited welding area, and the positive and negative poles of the batteries are easily short-circuited; at the same time, it also solves the high product development costs caused by the fact that different products require different molds because the connecting nickel strips cannot be standardized. problem, as well as reducing the number of jigs required for connecting nickel strips when soldering

[0007] The present invention also provides a method for manufacturing and assembling a high-voltage explosion-proof battery pack, which can solve the problem of long working hours and low production efficiency in the step of gluing the entire surface of the battery cell in the assembly process of the explosion-proof battery pack in the prior art. problems; and improved the problems of limited welding area, difficult operation, and easy short circuit of the positive and negative poles of the electric core when the electric core is connected by welding; at the same time, it reduces the need for the use of clamps when the nickel strip is welded. step
