Description
Technical Field
The utility model relates to the technical field of lithium batteries, in particular to a lithium battery with good pressure resistance.
Background
Along with the development of science and technology, the lithium cell has become the mainstream now, the lithium cell is a kind of battery that is used non-aqueous electrolyte solution by lithium metal or lithium alloy, lithium metal's chemical properties is very active, make the processing of lithium metal, save, use, require very high to the environment, current lithium cell structure crushing resistance is relatively poor, lead to the casing damaged because of the collision easily, thereby influence inner structure, the lithium cell can lead to the inflation because of generating heat during operation, current lithium cell structure is mostly in order to can fasten inside battery core, do not leave expandable space for the battery core, lead to the lithium cell to warp easily, influence its life-span.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides the lithium battery with good pressure resistance, and the problems in the background art can be effectively solved.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model provides a lithium cell that crushing resistance is good, includes battery body and shell, battery body locates in the shell, the shell include the epitheca and with the inferior valve of epitheca joint, the epitheca be equipped with the draw-in groove of inferior valve joint, the inferior valve be equipped with draw-in groove complex card strip subassembly, card strip subassembly includes buffering strip and fixture block, buffering strip and inferior valve fixed connection, the fixture block is the right trapezoid structure, one side that battery body was kept away from to the buffering strip is located to the fixture block.
Preferably, the clamping groove is provided with a reinforcing strip at one side close to the battery body, and the reinforcing strip is attached to the buffer strip.
Preferably, the lower case is provided with a buffer groove for realizing vertical movement of the reinforcing bar.
Preferably, the inner sides of the upper shell and the lower shell are respectively provided with an arc-shaped cushion pad, and two ends of the cushion pad are respectively attached to the battery body.
Preferably, a fixing plate is arranged at the joint of the cushion pad and the battery body.
Compared with the prior art, the utility model has the beneficial effects that:
can realize receiving when the shell extrudeing, the distance between epitheca and the inferior valve is dwindled, and buffering strip and fixture block upward movement in the draw-in groove, reinforce the strip and in the dashpot downstream, reinforce the strip and can play the reinforcing effect to buffering strip this moment, because epitheca and inferior valve distance dwindle simultaneously and make the blotter take place elastic deformation, make the whole elasticity that produces of shell, improve compressive capacity.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, a lithium battery with good pressure resistance comprises a battery body 1 and a housing 2, wherein the battery body 1 is arranged in the housing 2, the housing 2 comprises an upper housing 3 and a lower housing 4 connected with the upper housing 3 in a clamped manner, the upper housing 3 is provided with a clamping groove 31 connected with the lower housing 4 in a clamped manner, the lower housing 4 is provided with a clamping strip assembly 41 matched with the clamping groove 31, the clamping strip assembly 41 comprises a buffer strip 411 and a clamping block 412, the buffer strip 411 is fixedly connected with the lower housing 4, the clamping block 412 is in a right trapezoid structure, the clamping block 412 is arranged on one side of the buffer strip 411 away from the battery body 1, the clamping groove 31 is provided with a reinforcing strip 32 on one side close to the battery body 1, the reinforcing strip 32 is attached to the buffer strip 411, the lower housing 4 is provided with a buffer groove 42 for realizing vertical movement of the reinforcing strip 32, the inner sides of the upper housing 3 and the lower housing 4 are both provided with arc- shaped buffer pads 5, 5 both ends of blotter all laminate with battery body 1, 5 and 1 laminating department of battery body are equipped with fixed plate 51 of blotter, can realize when shell 2 receives the extrusion, the distance reduces between epitheca 3 and the inferior valve 4, buffering strip 411 and fixture block 412 upwards move in draw-in groove 31, consolidate strip 32 and move downwards in dashpot 42, it can play the reinforcing effect to buffering strip 411 to consolidate strip 32 this moment, simultaneously because epitheca 3 and inferior valve 4 distance reduce make 5 elastic deformation of blotter take place, make the whole elasticity that produces of shell 2, improve compressive capacity.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
