Description

Technical Field

[0001] The utility model relates to the technical field of battery box sealing rings, in particular to a battery box sealing ring for a new energy vehicle. Background Art

[0002] As an important component of pure electric vehicles, the battery box usually has a sealing ring inside that matches the shape of the battery box. The purpose of this is to ensure the sealing inside the battery box, prevent battery liquid leakage or foreign matter from entering the battery box, thereby protecting the safety and stable operation of the battery system.

[0003] The existing electric vehicle battery box sealing ring is generally assembled by a fitting and fixing method, that is, a sealing groove matching the sealing ring is left on the battery box cover, and then the sealing ring is directly embedded in the sealing groove and fixed;

[0004] However, the surface of the existing sealing ring is smooth, and after the sealing ring is embedded in the sealing groove, it is very easy to fall off when the cover is inverted. In addition, if a processing error occurs, the sealing groove is opened too deep, and the sealing ring will be embedded too deeply in the sealing groove, causing the cover of the battery box to fit directly with the box body, affecting the sealing effect. Utility Model Content

[0005] In order to solve the above technical problems, a new energy vehicle battery box sealing ring is provided, which solves the problem that the sealing ring has a smooth surface in the prior art, and then after the sealing ring is embedded in the sealing groove, it is very easy to fall off when the cover plate is inverted, and once a processing error occurs, the sealing groove is opened too deep, the sealing ring will be embedded too deeply in the sealing groove, causing the cover plate of the battery box to be directly fitted with the box body, affecting the sealing effect.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a new energy vehicle battery box sealing ring, including a battery box cover, an annular sealing groove opened on the battery box cover, and a new sealing component arranged in the annular sealing groove;

[0007] The novel sealing component includes a first sealing member arranged in the annular sealing groove and a second sealing member fixedly embedded in the bottom end surface of the first sealing member, a plurality of rubber protrusions are fixed around the inner and outer walls of the second sealing member, and a height-increasing gasket is detachably arranged on the bottom surface of the second sealing member.

[0008] Preferably, the rubber protrusion is in the shape of a right-angled trapezoid, and the hypotenuse of the rubber protrusion is distributed downward.

[0009] Preferably, a plurality of anti-slip grooves are formed on a surface of the rubber protrusion facing away from the second sealing member.

[0010] Preferably, a plurality of rubber plug posts are fixed around the top surface of the height-increasing gasket, and a plurality of rubber slots matching the rubber plug posts are arranged around the bottom surfaces of the second sealing member and the height-increasing gasket.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] (1) By setting the rubber protrusion, when the first seal and the second seal need to be embedded in the annular sealing groove as a whole, the oblique edge of the rubber protrusion contacts the opening of the annular sealing groove in advance and deforms under force, thereby reducing the obstruction to the embedding process of the first seal. After the first seal and the second seal are placed in the annular sealing groove as a whole, the rubber protrusion can make the side with the anti-skid groove close to the inner wall of the annular sealing groove due to its elastic characteristics. Compared with the sealing ring with a smooth surface in the prior art, the rubber protrusion can effectively enhance the friction and stability of the first seal and the second seal as a whole in the annular sealing groove, thereby preventing the first seal and the second seal from detaching from the annular sealing groove.

[0013] (2) By setting the rubber plug and the rubber slot, the rubber plug is aligned and inserted into the rubber slot on the bottom surface of the second seal or the bottom surface of the heightened gasket, so as to quickly connect the heightened gasket to the second seal, or connect multiple groups of heightened gaskets, and then multiple heightened gaskets can be assembled at the bottom of the second seal to increase the overall thickness of the first seal and the second seal, so that the first seal and the second seal can be embedded in the annular sealing grooves of different depths to prevent the first seal and the second seal from being embedded too deep and affecting the sealing effect.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0022] Reference Figure 1-5 As shown, a new energy vehicle battery box sealing ring comprises a battery box cover plate 1, an annular sealing groove provided on the battery box cover plate 1, and a new sealing component arranged in the annular sealing groove;

[0023] The novel sealing component comprises a first sealing member 2 arranged in an annular sealing groove and a second sealing member 3 fixedly embedded on the bottom end surface of the first sealing member 2, and a plurality of rubber protrusions 4 are fixedly arranged on the inner and outer walls of the second sealing member 3;

[0024] The rubber protrusion 4 is in a right-angle trapezoidal shape, and the oblique side of the rubber protrusion 4 is distributed downward;

[0025] A plurality of anti-skid grooves 5 are provided on the surface of the rubber protrusion 4 facing away from the second sealing member 3;

[0026] By setting the rubber protrusion 4, when it is necessary to embed the first seal 2 and the second seal 3 as a whole into the annular sealing groove, the hypotenuse of the rubber protrusion 4 will contact the opening of the annular sealing groove in advance and deform under force, thereby reducing the obstruction to the embedding process of the first seal 2. After the first seal 2 and the second seal 3 are placed in the annular sealing groove as a whole, the rubber protrusion 4 can make the side with the anti-skid groove 5 close to the inner wall of the annular sealing groove due to its elastic characteristics. Therefore, compared with the sealing ring with a smooth surface in the prior art, the rubber protrusion 4 can effectively enhance the friction and stability of the first seal 2 and the second seal 3 as a whole in the annular sealing groove, thereby preventing the first seal 2 and the second seal 3 from escaping from the annular sealing groove.

[0027] Further, refer to Figure 2-4 As shown, it is worth noting that a height-increasing gasket 6 is detachably provided on the bottom surface of the second sealing member 3;

[0028] A plurality of rubber plug posts 7 are fixed around the top surface of the heightening gasket 6, and a plurality of rubber slots 8 matching the rubber plug posts 7 are opened around the bottom surfaces of the second sealing member 3 and the heightening gasket 6;

[0029] By setting the rubber plug 7 and the rubber slot 8, the rubber plug 7 is aligned and inserted into the rubber slot 8 on the bottom surface of the second seal 3 or the bottom surface of the heightened gasket 6, so as to quickly connect the heightened gasket 6 to the second seal 3, or connect multiple groups of heightened gaskets 6, and then multiple heightened gaskets 6 can be assembled at the bottom of the second seal 3 to increase the overall thickness of the first seal 2 and the second seal 3, so that the first seal 2 and the second seal 3 can be embedded in annular sealing grooves of different depths as a whole, so as to prevent the first seal 2 and the second seal 3 from being embedded too deeply and affecting the sealing effect.
