Problems solved by technology

[0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, which brings a lot of dark consequences. When the battery is in an extreme working environment, due to the occurrence of short circuit, etc., it will easily come into contact with oxygen o...

Method used

Principle of work: drive damping spring 7 by explosion-proof plate 6 and be connected with clamping plate 8 and form installation conflicting structure, have certain cushioning force, utilize connecting device 9 to be connected with angle plate 5 and explosion-proof plate 6 simultaneously, make angle plate 5 And the explosion-proof plate 6 has the effect of surrounding the lithium battery. Connecting all the structures together can better play the explosion-proof effect and avoid explosion damage. Under the effect of head 13, avoid explosion and impel cap body 2 to drop and cause damage.

With reference to Fig. 1-4, a kind of explosion-proof device of lithium battery comprises shell 1, and the upper end side of shell 1 is connected with cap body 2 by hinge 10, and the inner cavity bottom end of shell 1 is provided with negative ele...

Abstract

The invention relates to the technical field of explosion-proof devices and in particular to explosion-proof equipment of a lithium battery. The explosion-proof equipment comprises a housing. An anode conducting strip is arranged on one side, close to the housing, of a cap body; corner plates are arranged on four corners of the inner wall of the housing; an explosion-proof plate is arranged between every two corner plates; locking boards are connected to one sides, far from the housing, of the explosion-proof plates through a plurality of damping springs; the corner plates and the explosion-proof plates are connected through connecting devices; a fixed clamp plate is arranged on one side of the housing; a notch is formed in the middle of one side, far from a hinge, of the fixed clamp plate; a clamping slot is formed in the middle of the fixed plate; one side, far from the hinge, of the cap body, is connected to a movable locking bar matched with the clamping slot through a pin roll; and a hammer-shaped head is arranged on the lower end of the moving locking bar. Compared with the prior art, the explosion-proof equipment provided by the invention is simple in structure, good in explosion-proofness, high in usability, practical and safer and small in potential safety hazard, brings more beneficial effects, and can avoid fire influence caused by explosion.

Example Embodiment

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0015] Reference Figure 1-4 , An explosion-proof device for a lithium battery, comprising a casing 1, the upper side of the casing 1 is connected with a cap 2 through a hinge 10, a negative conductive sheet 4 is provided at the bottom end of the inner cavity of the casing 1, and the cap 2 is close to the casing One side of the body 1 is provided with a positive conductive sheet 3, and the four corners of the inner wall of the housing 1 are provided with gussets 5, and an explosion-proof plate 6 is arranged between every two gussets 5, and the middle of the gusset 5 and the explosion-proof plate 6 are both A jack is provided, and the connecting device 9 includes an enclosure 91 that matches the jack. The middle of the plurality of enclosures 91 are equidistantly provided with through holes 92, and the plurality of through holes 92 are connected by a connecting chain 93, which makes the connection more stable. Connect a large amount of power to ensure explosion-proof performance and improve explosion-proof effect.

[0016] The side of the explosion-proof plate 6 away from the housing 1 is connected with a clamping plate 8 through a plurality of shock-absorbing springs 7, the angle plate 5 and the explosion-proof plate 6 are connected by a connecting device 9, and a fixing splint 14 is provided on one side of the housing 1 to fix The splint 14 is provided with a notch 15 in the middle of the side away from the hinge 10, and the middle of the fixed splint 14 is provided with a clamping groove 16, and the side of the cap 2 away from the hinge 10 is connected with a movable card matching the clamping groove 16 through a pin 11 The rod 12 is provided with a hammer head 13 at the lower end of the movable clamping rod 12. The diameter of the upper end of the hammer head 13 is larger than the diameter of the clamping groove 16, which can prevent the cap body 2 from falling off by using the hammer head 13 during explosion. Increase the damage caused by the explosion.

[0017] Working principle: The damping spring 7 is driven by the explosion-proof plate 6 to connect with the clamping plate 8 to form an installation interference structure, which has a certain buffer force. At the same time, the angle plate 5 and the explosion-proof plate 6 are connected by the connecting device 9 to make the angle plate 5 and the explosion-proof plate 6 It has the effect of enclosing the lithium battery. Connecting all the structures together can better achieve the explosion-proof effect and avoid explosion damage. At the same time, the movable clamp rod 12 and the clamping slot 16 are used to cooperate, and the hammer head 13 Under the action, the explosion can prevent the cap body 2 from falling and causing damage.

[0018] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution of the present invention The equivalent replacement or change of the inventive concept thereof shall be covered by the protection scope of the present invention.
