Description
Technical field
It the utility model is related to a kind of modified ring structure of cylinder type lithium battery combination safety cap.
Background technology
There is potential safety hazard in the structure of existing cylinder type lithium battery combined seal ring body seal circle.Because structure does not conform to
Reason, find that the phenomenon of leakage occurs in the product for having a ten thousandth in factory testing.Passive detection, still there is the lithium with hidden danger
Battery comes into the market, and with the mobile devices such as electric automobile, once occurring leakage in operation, there is the danger for causing fire,
This at home and abroad has been reported on media.
Although the possibility very little of leakage, the cylinder type lithium battery number that each automobile uses up to 4000~7000,
And the phenomenon of lithium battery leakage on the mobile devices such as electric automobile is loaded in often after the operation of long period, vibration
Produce.Nowadays, the detection before cylinder type lithium battery manufacturer dispatches from the factory is passive, there is a possibility that missing inspection.Use
Factory's detection is qualified, but after operation after a while, still there is the danger of leakage.In a word, do not provide against hidden trouble fundamentally, endanger
It is dangerous to be constantly present.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, and processing is convenient, substantially increases the peace of battery
Quan Xing, and hardly increase production cost and price, extensively the cylinder type lithium battery by user's favor combines improving for safety cap
Type ring structure.
The technical solution of the utility model is a kind of modified ring structure of cylinder type lithium battery combination safety cap,
Including sealing ring main body, the section of the sealing ring main body takes the shape of the letter U structure setting, the vertical and horizontal connection of the U-shape structure
End outer surface indent is provided with a groove and forms arc drift angle, and sealing ring envelope is correspondingly arranged in the sealing ring main body
Mouthful, the L-shaped structure setting in section of sealing ring sealing, the sealing ring sealing be correspondingly arranged in the upper part of groove and with
Arc drift angle is correspondingly connected to form one structure.
In one preferred embodiment of the utility model, the transverse end upper surface of the sealing ring sealing is in what is tilted down
Arcuate structure is set.
In one preferred embodiment of the utility model, the transverse end lower surface of sealing ring sealing is inclined upwardly setting
And connection corresponding with the tapered structure in transverse end upper surface.
In one preferred embodiment of the utility model, appearance that the longitudinal end of sealing ring sealing connects with transverse end
Face is set in arc-shaped structure.
In one preferred embodiment of the utility model, the longitudinal direction of longitudinal end and the sealing ring sealing of the sealing ring main body
The outer surface at end keeps flushing setting.
In one preferred embodiment of the utility model, the bottom of the sealing ring sealing is higher than the sealing ring main body
Bottom.
The modified ring structure described in the utility model that safety cap is combined for a kind of cylinder type lithium battery, this practicality are new
Type is simple in construction, and processing is convenient, substantially increases the security of battery, and hardly increases production cost and price,
Extensively favored by user.
Brief description of the drawings
Fig. 1 is that a kind of modified ring structure one of cylinder type lithium battery combination safety cap of the utility model is preferably implemented
Schematic cross-section in example；
Fig. 2 is the enlarged drawing of Fig. 1 part A.
Embodiment
Preferred embodiment of the present utility model is described in detail below, so that advantages and features energy of the present utility model
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to the scope of protection of the utility model.
The modified ring structure described in the utility model that safety cap is combined for a kind of cylinder type lithium battery, such as Fig. 1 knots
Close shown in Fig. 2, including sealing ring main body 1, the section of the sealing ring main body 1 takes the shape of the letter U structure setting, the U-shape structure it is vertical
To being provided with a groove 3 with lateral connection end outer surface indent and forming arc drift angle 4, corresponded in the sealing ring main body 1
Sealing ring sealing 2, the L-shaped structure setting in section of the sealing ring sealing 2 are provided with, the sealing ring sealing 2 is correspondingly arranged
Upper part and the structure that is connected to form one corresponding with arc drift angle 4 in groove 3, the transverse end upper table of the sealing ring sealing 2
Face is in that the arcuate structure that tilts down is set, the transverse end lower surface of the sealing ring sealing 2 be inclined upwardly setting and with transverse direction
Hold the tapered structure in upper surface is corresponding to connect, the outer surface that the longitudinal end of the sealing ring sealing 2 connects with transverse end is in circular arc
Shape structure setting, the outer surface of the longitudinal end of longitudinal end and the sealing ring sealing 2 of the sealing ring main body 1 keep flushing setting,
The bottom of the sealing ring sealing 2 is higher than the bottom of the sealing ring main body 1.
By change combination safety cap sealing ring structure as shown in Figure 2, with the cylindrical lithium electricity of 1.8 centimetres of diameter
Exemplified by pond combination safety cap, the similar products of other diameters can be covered, the radius of the arc-shaped structure of sealing ring sealing is
The angle that 0.1mm, the longitudinal end of sealing ring sealing and the lower surface of transverse end are formed is 60 °, and the sealing ring sealing is indulged
It is 0.1mm to the thickness at end, the height of the longitudinal end of the sealing ring sealing is 1.39mm, is sealed with this to strengthen sealing ring
Sealing, so as to prevent the hidden danger of leakage.The application of remaining size is scaled up or reduced.
In terms of the conclusion of detection, the possibility of leakage is reduced to hundred a ten thousandths, and almost zero event from a ten thousandth
Barrier, is calculated, security is up to more than 100 times in theory.
Increased ring structure hardly increases production cost and price, is similarly subjected to the welcome of user.
The modified ring structure described in the utility model that safety cap is combined for a kind of cylinder type lithium battery, this practicality are new
Type is simple in construction, and processing is convenient, substantially increases the security of battery, and hardly increases production cost and price,
