Waterproof fastening shell

Abstract

The invention provides a waterproof fastening shell. The waterproof fastening shell comprises an upper shell body and a lower shell body, wherein the upper shell body comprises an upper bottom surfaceand a waterproof glue binding wall which surrounds the upper bottom surface for one circle and protrudes downward; the waterproof glue binding wall is provided with a plurality of convex clamping hooks; the lower shell body comprises a lower bottom surface, and a first side wall and a second side wall which surround the lower bottom surface for one circle and protrude upward; the first side wallis arranged at the outer side of the second side wall; a clamping hook groove matched with the clamping hooks is formed between the first side wall and the second side wall; a U-shaped groove for containing the waterproof glue binding wall is formed in the second side wall. With the adoption of the technical scheme, the clamping hooks and the clamping hook groove are adopted, and the shell is clamped without the need of an additional tool clamp, so that the time and the clamp cost are reduced; the shell body is fastened by utilizing the clamping hooks, and rebound stress can be balanced, so that the risk that waterproof glue is separated from the two shells is effectively reduced; an additional screw locking procedure is not needed, so that the procedure cost is reduced; the waterproof glue is used for preparing a waterproof layer, so that the risk that a waterproof ring is not assembled in place is also avoided.

Problems solved by technology

[0002] In the prior art, in the assembly process of the car radar casing, there are three common waterproof fastening methods. The first method is to use only waterproof glue, that is, when the two casings are combined, the contact part is filled with waterproof glue, and then the fastening method is fixed with tooling. The clamp clamps the two shells. After the waterproof glue is cured, the fixture is loosened to achieve the purpose of both waterproofing and fastening the shell. The disadvantage of this method is that the curing time of the waterproof glue is long, and the fixture needs to be continuously clamped during the curing period. , generally requires more time cost and tooling fixture cost, and due to the inevitable manufacturing tolerance and deformation of the shell, after the tooling fixture is loosened, when the rebound stress caused by the tolerance and deformation is greater than the adhesive force of the waterproof glue, the waterproof glue and the two There is a risk of detachment of the two shells, and the waterproof function will be invalid at this time

[0003] The second waterproof fastening method is waterproof glue plus screw fastening, that is, screw holes are set on both shells. When combined with each other, the contact part is filled with waterproof glue, and then the two shells are locked with screws. After the waterproof glue is cured , and finally achieve the purpose of both waterproofing and fastening the two shells. The disadvantage of this method is that additional screws and locking screws are required, and there is a risk of the screws being disassembled at will, resulting in product damage and waterproof failure.

[0004] The third waterproof fastening method is to fasten the waterproof ring (silicone or rubber) with screws. Both shells are provided with screw holes. When combined with each other, the waterproof ring is placed on the contact part, and then the two shells are locked with screws and pressed tightly. The waterproof ring finally achieves the purpose of waterproof fastening. The disadvantage of this method is that it requires additional screws and locking screws, and there is a risk of the screws being disassembled at will, resulting in product damage and waterproof failure. In addition, during the assembly process, the waterproof The circle is inside the two shells and is always in an invisible state. There is a risk of improper assembly. If the assembly is not in place, the waterproof will fail
