The radar in the prior art has the problems of poor assembly process, high dimensional requirement precision, precise matching requirement, destructive disassembly, incapability of repeated disassembly test and the like.
An object of this embodiment is to provide a radar waterproof construction for it is complicated to solve millimeter wave radar waterproof construction among the prior art, the inconvenient technical problem of dismouting.
The principle and the implementation of the radar waterproof structure of the present embodiment will be described in detail below, so that those skilled in the art can understand the radar waterproof structure of the present embodiment without creative efforts.
As shown in fig. 1, the present embodiment provides a waterproof radar 100, where the waterproof radar 100 includes: an upper case 110, a lower case 120 matched with the upper case 110, and a waterproof elastic structure 130.
In this embodiment, the waterproof elastic structure 130 is disposed around the inner sidewall of the upper housing 110 and is injection-molded with the upper housing 110 into a whole through a mold, so as to realize sealing and waterproofing between the upper housing 110 and the lower housing 120 by being pressed by the surface of the lower housing 120 when the lower housing 120 is connected to the upper housing 110.
Specifically, the waterproof elastic structure 130 surrounds the inner sidewall of the upper housing 110, and forms a ring-shaped structure matching with the ring-shaped structure formed by the inner sidewall of the upper housing 110.
As shown in fig. 2, the inner side wall of the upper casing 110 defines a rectangular ring, and correspondingly, the annular structure formed by the waterproof elastic structure 130 is also correspondingly shaped as a rectangular ring.
In this embodiment, waterproof elastic structure 130 with go up casing 110 and pass through the mould and mould plastics integratively, make waterproof elastic structure 130 with go up between the casing 110 and need not to seal again, reduced the risk of leaking, reduced the spare part of radar assembly moreover, only need with waterproof elastic structure 130 with go up casing 110 through mould plastics structure after an organic whole with down casing 120 assemble can, the part is few, assembly structure is simple, convenient assembling, and when going up casing 110 and casing 120 separation down, need not to pull down waterproof elastic structure 130, only will go up casing 110 with casing 120 separation down can, can not destroy last casing 110 and casing 120 down.
Wherein the waterproof elastic structure 130 is located in the inner sidewall of the upper housing 110 at a position corresponding to a position where the lower housing 120 is installed in the upper housing 110. That is, the top of the waterproof elastic structure 130 is flush or approximately flush with the top end of the inner sidewall, and extends downwards from the top end of the inner sidewall to form the height of the waterproof elastic structure 130, and the height of the waterproof elastic structure 130 matches the height of the lower housing 120 in the upper housing 110.
When the lower shell 120 is assembled with the upper shell 110, the lower portion of the lower shell 120 extends into the upper shell 110, the outer surface of the lower shell 120 contacts with the waterproof elastic structure 130, the waterproof elastic structure 130 is pressed by the outer surface of the lower shell 120, and a resilience force is applied to the outer surface of the lower shell 120, so that the waterproof elastic structure 130 is tightly attached to the outer surface of the lower shell 120, thereby achieving the effect of sealing and waterproofing with the lower shell 120.
In this embodiment, the thickness of the waterproof elastic structure 130 is greater than the distance between the inner sidewall of the upper housing 110 and the outer sidewall of the lower housing 120.
