Abstract

The utility model discloses a kind of battery modules seal ring, it is characterized in that: comprise the exterior seal ring and inner seal ring that are connected as one by connection Stamping Steel Ribbon, the face of the equidirectional of described exterior seal ring and inner seal ring is plane, and the another side of exterior seal ring and inner seal ring is equipped with raised line.

Description

A kind of battery modules seal ring
Technical field
The utility model relates to a kind of seal ring, particularly a kind of battery modules seal ring.
Background technique
At present, battery is more and more applied in some field, and in these areas battery operationally distributed, unnecessary heat must remove the phenomenon that prevents battery overheated timely.Particularly as lithium ion battery and Ni-MH battery, these batteries have been used on hybrid-power electric vehicle and other application apparatus, these cell output are large, thus the heating value of itself is also relatively very large, traditional cooling or air cooling way naturally can not meet the cooling requirements of battery in above-mentioned environment, thus A designer person adopts at battery additional heat conduction board absorption cell heat outward at present, the mode that thermal conductor dispels the heat is adopted between heat conduction board, thus good heat dissipation effect, but aforesaid way have employed thermal conductor heat radiation, and thermal conductor is mainly made up of water, therefore the sealing of battery pack just becomes vital problem, if thermal conductor leakage can cause extremely dangerous consequence.For the problems referred to above, the utility model devises a kind of waterproof grommet, can play seal action well, certainly also can be used for the leakage preventing other cooling mediums.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of battery modules seal ring of good airproof performance.
The utility model solves the technological scheme that its technical problem adopts:
A kind of battery modules seal ring, it is characterized in that: comprise the exterior seal ring and inner seal ring that are connected as one by connection Stamping Steel Ribbon, the face of the equidirectional of described exterior seal ring and inner seal ring is plane, and the another side of exterior seal ring and inner seal ring is equipped with raised line.
The cross-sectional profiles of described raised line is a circular arc.
Described exterior seal ring is quadrilateral structure; Described inner seal ring comprises four second Stamping Steel Ribbons and four first Stamping Steel Ribbons parallel with exterior seal ring four limit, described second Stamping Steel Ribbon and the first Stamping Steel Ribbon are connected to form closed loop thus form inner seal ring, described connection Stamping Steel Ribbon is made up of the end extension of the second Stamping Steel Ribbon, thus inner seal ring and exterior seal ring is connected.
Described second Stamping Steel Ribbon becomes 45 with the angle of the first adjacent Stamping Steel Ribbon 0.
Described tab parallel is provided with many.
The beneficial effects of the utility model are: the utility model comprises two by connecting the exterior seal ring that connects as one of Stamping Steel Ribbon and inner seal ring, the face of the equidirectional of described exterior seal ring and inner seal ring is plane, and the another side of exterior seal ring and inner seal ring is equipped with raised line, said structure exterior seal ring and inner seal ring form the multi-sealing structure of Double seal ring, not only substantially increase sealing effect, and the gap location of bolt between exterior seal ring and inner seal ring connecting two heat conduction boards passes, bolt is while locking two heat conduction board, also make heat conduction board compression exterior seal ring and inner seal ring be formed to be sealed and matched closely, and exterior seal ring and inner seal ring are just in time distributed in the both sides of bolt, stressed also very even, more ensure that the leakproofness of sealing, the cooling mediums such as the liquid between strict guarantee two heat conduction board or gas can not be revealed.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model;
Fig. 2 is cross sectional view of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model discloses a kind of battery modules seal ring, in this instantiation, the cooling structure that sealing circle is applied to fuel cell plays seal action, this cooling structure comprises two heat-conducting plates, wherein a heat-conducting plate has groove, seal ring comprises two by connecting the exterior seal ring 2 that connects as one of Stamping Steel Ribbon 1 and inner seal ring 3, this exterior seal ring 2 is quadrilateral structure, be specially rectangular, inner seal ring 3 comprises four second Stamping Steel Ribbons 4 and four first Stamping Steel Ribbons 5 parallel with exterior seal ring 2 four limit, second Stamping Steel Ribbon 4 becomes 45 with the angle of the first adjacent Stamping Steel Ribbon 5 0described second Stamping Steel Ribbon 4 and the first Stamping Steel Ribbon 5 are connected to form closed loop thus form inner seal ring 3, the overall structure of inner seal ring 3 is the rectangular after the chamfering of a kind of corner, connect Stamping Steel Ribbon 1 to be made up of the end extension of the second Stamping Steel Ribbon 4, thus inner seal ring 3 and exterior seal ring 2 are connected, exterior seal ring 2 in said structure, inner seal ring 3 and connect Stamping Steel Ribbon 1 to be integrated injection molding aft-loaded airfoil shaping, thus just can have good sealability.
Described exterior seal ring 2 is plane with the face of the equidirectional of inner seal ring 3, and exterior seal ring 2 and the another side of inner seal ring 3 are equipped with raised line 6, plane seals with the bottom land of the groove of a heat-conducting plate and contacts, raised line 6 part then exceeds the surface of heat-conducting plate, when two heat-conducting plates are close to, raised line 6 is made to be close to sealing completely with the surface of another heat-conducting plate by extruding.The designing points of said structure is: if heat-conducting plate and the common seal ring of raised line 6 that do not have will realize good sealing, the area planar degree that heat-conducting plate surface contacts with seal ring requires high, if out-of-flatness, necessarily to be put on by heat-conducting plate with very large pressure and seal ring makes seal ring produce moderate finite deformation just to make up the difference of height that out-of-flatness brings.But, the pressure of two heat-conducting plate lockings is limited, thus, people can only improve the flatness of the bottom land of seal ring and heat-conducting plate and heat conduction film trap to ensure good sealing as far as possible, but above-mentioned measure difficulty of processing is large, cost is high, thus the initial contact surface with heat-conducting plate is reduced by raised line 6, particularly the cross-sectional profiles of described raised line 6 is a circular arc, when easily producing larger elastic strain after raised line 6 pressurized, thus easily irregular region is filled up, and additionally need not increase very large pressure and just can reach and well seal contact.
As the expansive approach of said structure, the cross section of raised line 6 can be triangle or trapezoidal etc., and raised line 6 can be many, and two of such as parallel arrangement or three etc., above-mentioned structure can reach the effect that in this example, structure is identical or close.
Above to a kind of battery modules seal ring that the utility model embodiment provides, be described in detail, apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
