Abstract
The dumbbell type sealing ring that the utility model discloses a kind of on power battery cabinet, it is characterised in that: the sealing ring uses dumbbell type structure, including the identical sealing of two structures, passes through transition part integrated injection molding between two sealings；The section of two sealings is formed as diamond structure, interior to be equipped with centre bore.Dumbbell type sealing ring provided by the utility model on power battery cabinet, after cabinet is coupled between upper box and lower box, the identical sealing in both ends in this way forms sealing, twice primary seal is formed from inside to outside, it applies and can effectively improve the leakproofness of battery of electric vehicle cabinet in battery of electric vehicle cabinet, to improve the reliability of Battery case, guarantees the normally travel of electric vehicle, be of great practical significance.
Description
Technical field
The utility model belongs to vehicle technology field more particularly to a kind of dumbbell type on power battery cabinet is close
Seal.
Background technique
With the continuous expansion of electric vehicle use scope, vehicle technology is just fast-developing, electric vehicle and its component it is each
Kind technology is just increasingly mature and perfect.As the essential core component of electric vehicle, the development of battery attracts attention always, electricity
The performance in pond is stepping up, and the structure of each component of battery of electric vehicle is also constantly improve.One as battery of electric vehicle technology
A important subject, the leakproofness of battery of electric vehicle cabinet is by the safety of extreme influence battery.Once battery of electric vehicle mould
The leakproofness of group goes wrong, and the circuit and battery modules inside Battery case will face great risk, once and circuit
And battery modules go wrong, whole electric vehicle will sink into state of paralysis.
Utility model content
In view of the problems of the existing technology, the utility model provide a kind of good seal performance for power battery box
Dumbbell type sealing ring on body.
The utility model is realized in this way a kind of dumbbell type sealing ring on power battery cabinet, the sealing
Circle uses dumbbell type structure, including the identical sealing of two structures, between two sealings by transition part integrated injection molding at
Type；The section of two sealings is formed as diamond structure, interior to be equipped with centre bore.
The side wall of the sealing is equipped with the exhaust outlet being connected to centre bore.The design of the structure passes through row after compression
The air in centre bore is discharged in port, further realizes compressive deformation, improves sealing effect, while to when generation explosion in cabinet
The high pressure of generation has the function of having directional exhaust.
The transition part is equipped with through-hole.The design of the structure can be fixedly connected using fastener with by seal case,
Improve the stability of the installation fastness of sealing ring.
The utility model has the advantage that and good effect: provided by the utility model for mute on power battery cabinet
Bell formula sealing ring, after cabinet is coupled between upper box and lower box, the identical sealing in such both ends forms close
Envelope forms twice primary seal from inside to outside, applies and can effectively improve the close of battery of electric vehicle cabinet in battery of electric vehicle cabinet
Feng Xing guarantees the normally travel of electric vehicle, is of great practical significance to improve the reliability of Battery case.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain that this is practical
It is novel, it is not used to limit the utility model.
It in order to further illustrate the specific features of the utility model, is described in detail below with reference to relevant drawings, specifically
Referring to Figure 1 to Fig. 3.
A kind of dumbbell type sealing ring on power battery cabinet, the sealing ring 10 use dumbbell type structure, including
The identical sealing 11 of two structures passes through 310 integrated injection molding of transition part between two sealings；It is set on the transition part
There is through-hole 12, the design of the structure can be fixedly connected with by seal case using fastener, improve firmly installing for sealing ring
The stability of property.Such as staking nut is installed in the through-hole, the staking nut and battery box cover upper flange flanging
Configuration pulling rivet bolt 22 is threadedly coupled in mounting hole；The section of above-mentioned two sealing is formed as diamond structure, is inside equipped with
Heart hole 13, the side wall of sealing are equipped with the exhaust outlet 14 being connected to centre bore.Had using the sealing ring of this kind of structure good
Sealing performance, while also there is sealing compensation, while to the work when the high pressure for generating explosion generation in cabinet with having directional exhaust
With.After Battery case is coupled between upper box 20 and lower box 21, applying can have in battery of electric vehicle cabinet
The leakproofness that effect improves battery of electric vehicle cabinet guarantees the normally travel of electric vehicle to improve the reliability of battery, has weight
Big production practices meaning.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
