[0036] The utility model provides a sealing ring 100, which is used for sealingly connecting a cover body and a box body of a battery box of a new energy vehicle.

[0037] See also Figures 1 to 5In one embodiment of the utility model, the sealing ring 100 includes a ring body 1, a first annular skeleton 2 and a second annular skeleton 3. The upper and lower ends of the ring body 1 are respectively provided with a first annular groove 11 and a second annular groove. The bottom wall of the first annular groove 11 is provided with a connecting through hole 12 connected to the second annular groove; the first annular skeleton 2 is accommodated in the first annular groove 11, and a through-mounting through hole 21 is provided on one side of the first annular skeleton 2 corresponding to the connecting through hole 12; the second annular skeleton 3 is accommodated in the second annular groove, and the second annular skeleton 3 is close to the first annular A fixed post 4 is provided on one side of the frame 2, and the fixed post 4 includes a connecting section 41 and a bending section 42, one end of the connecting section is connected to the second annular frame 3, and the other end of the connecting section is connected to the bending section 42; wherein the fixed post 4 has a fixed state, in which the fixed post 4 is provided with a connecting through hole 12 and a mounting through hole 21, the bending section 42 is arranged at an angle with the connecting section 41, and the bending section 42 abuts against a side of the first annular frame 2 away from the second annular frame 3, so that the first annular frame 2, the second annular frame 3 and the ring body 1 are connected as a whole;

[0038] The technical solution of the utility model can improve the overall strength of the sealing ring 100 by providing a first annular groove 11 and a second annular groove at the upper and lower ends of the ring body 1, and respectively arranging a first annular skeleton 2 and a second annular skeleton 3 in the first annular groove 11 and the second annular groove, thereby avoiding the problem of breakage and deformation of the sealing ring 100 when the sealing ring 100 is squeezed. At the same time, a fixed clamping column 4 is provided on the second annular skeleton 3 so that the bending section 42 of the fixed clamping column 4 can fix the first annular skeleton 2, the second annular skeleton 3 and the ring body 1 as a whole, thereby enhancing the connection stability between the first annular skeleton 2 and the second annular skeleton 3 and the ring body 1, and enhancing the strength of the inner wall of the ring body 1, avoiding the problem of damage and deformation of the inner wall of the ring body 1 when the connection movement with the external structure is performed, further enhancing the strength and deformation resistance of the sealing ring 100, and greatly improving the service life of the sealing ring 100 body.

[0039] See also Figure 1 and Figure 2 In one embodiment of the present application, the sealing ring 100 further includes a sealing skirt 5, which is disposed on the outer side wall of the ring body 1. By providing the sealing skirt 5, when the free end of the sealing skirt 5 contacts the cover body, the sealing skirt 5 will be opened and folded under the action of friction, thereby achieving a sealed installation.

[0040] Furthermore, in one embodiment of the present application, the sealing skirt 5 is tilted. Since the sealing skirt 5 is tilted, the free end of the sealing skirt 5 should be installed on the cover body first during installation so that it can be easily folded. In addition, in order to make the sealing skirt 5 more firmly sealed as it is folded, the thickness of the sealing skirt 5 from the fixed end to the free end gradually decreases. When the free end is folded, the greater the degree of folding, the greater the thickness of the skirt after folding, thereby making the sealing ring 100 more firmly sealed.

[0041] In order to further facilitate the folding of the sealing skirt 5 , in one embodiment of the present application, the angle between the sealing skirt 5 and the outer side wall of the ring body 1 is A, and 10°≤A≤25°.

[0042] In one embodiment of the present application, the outer wall of the ring body 1 is provided with a third annular groove 13, and one end of the ring body 1 is provided with a glue injection port 14 connected to the third annular groove 13. In this way, waterproof glue can be injected into the third annular groove 13 through the glue injection port 14. The waterproof glue is usually a soft material with certain ductility and elasticity, which can adapt to surfaces of different shapes and form a seal between surfaces. This elasticity allows the waterproof glue to fill the tiny gaps on the surface, thereby effectively preventing water from penetrating. This leaves no gap between the ring body 1 and the cover body, making the connection tighter, and further improving the sealing ability of the sealing ring 100.

[0043] See also Figure 4 In one embodiment of the present application, the bending section 42 includes two bending arms 422 arranged opposite to each other, and the two bending arms 422 are arranged at intervals at one end of the connecting section 41 away from the second annular skeleton 3; in the fixed state, the two bending arms are bent in two opposite directions to respectively abut against the side of the first annular skeleton 2 away from the second annular skeleton 3. The arrangement of the two bending arms 422 makes it difficult for the fixing clamp 4 to fall out of the connecting through hole 12 and the mounting through hole 21, further enhancing the stability of the connection between the first annular skeleton 2 and the second annular skeleton 3.

[0044] In order to further improve the sealing ability of the sealing ring 100, in one embodiment of the present application, the first annular groove 11 is filled with waterproof glue, which can fill the gap between the connecting through hole 12 and the mounting through hole 21, thereby effectively preventing moisture penetration.

[0045] In one embodiment of the present application, the first annular skeleton 2 and the second annular skeleton 3 are made of metal steel. The strength and anti-deformation ability of the sealing ring 100 can be further improved by using the metal steel having the characteristic of high hardness as the material for making the first annular skeleton and the second annular skeleton 3.

[0046] In one embodiment of the present application, the bottom wall of the first annular groove 11 is provided with a plurality of connecting through holes 12; the first annular skeleton 2 is provided with a plurality of mounting through holes 21, and the plurality of mounting through holes 21 are correspondingly connected with the plurality of connecting through holes 12; the second annular skeleton 3 is provided with a plurality of fixing posts 4 on one side close to the first annular skeleton 2; wherein each fixing post 4 is correspondingly provided with a connecting through hole 12 and a mounting through hole 21. In this way, the strength of the sealing ring 100 body itself can be further enhanced, the anti-deformation effect of the ring body 1 can be improved, and the stability effect of the connection between the first annular skeleton 2 and the second annular skeleton 3 and the ring body 1 can be enhanced.

[0047] The utility model also proposes a new energy vehicle battery box, which includes a cover, a box body and a sealing ring 100. The specific structure of the sealing ring 100 refers to the above embodiment. Since the new energy vehicle battery box adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the sealing ring 100 is used to seal the cover and the box body.

[0048] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
