Detailed Description

The utility model will be described in detail below with reference to the drawings and detailed description thereof.

Referring to fig. 1-2, an external monitoring device comprises a bracket 2, wherein the bracket 2 is a mounting plate fixed with an automobile, a protective cover is fixed on one side of the mounting plate, and a space between the bracket 2 and the protective cover is a position for fixing a lens 5.

The protection cover comprises an upper shell 1, a lower shell 6, a front shell 4 and a rear shell 3, a through hole 31 is arranged on the rear shell 3, and an observation port of the lens 5 extends out of the through hole 31.

The inner wall of the protective cover is provided with a wind shield 41, the wind shield 41 and the protective cover form an air channel together, an air inlet 21 of the air channel is arranged on the support 2, an air outlet 32 of the air channel is arranged at the side position of the through hole 31, the air outlet 32 is a disturbing hole, and the lens 5 is arranged in the air channel.

As shown in fig. 3, in order to protect the observation port of the lens 5, the lens 5 includes a lens body 52, the lens body 52 is connected to the observation tube 511, a flange plate 51 is fixed on the outer side of the observation tube 511, and the flange plate 51 extends out from the through hole 31.

As shown in fig. 3, for defrosting, a ring-shaped heating film 53 is adhered and fixed to the flange plate 51.

In order to increase the cleaning force, as shown in fig. 4, the air channel at the lens 5 is narrowest. Thus, a closed air duct cavity is formed, the air flow strength is enhanced, the turbulence is weakened, and meanwhile, light foreign matters around the lens can be blown away.

The flange plate 51 is made of aluminum alloy, and the heating diaphragm 53 is made of FPC. A flexible printed circuit board (Flexible Printed Circuit abbreviated as FPC) is a flexible printed circuit board which is made of polyimide or polyester film as a base material and has high reliability and excellent flexibility.

The working principle is as follows:

referring to fig. 4, during running of the automobile, wind is driven to blow out from the air inlet 21 and the air outlet 32, so that sundries such as dust at the lens 5 can be blown away, and self-cleaning is realized.

If ice and snow exist, the ice and snow can be heated through the heating membrane 53, and heat is transmitted to the lens 5 through the flange plate 51, so that the ice and snow can be conveniently removed.

The utility model is characterized in that:

s1, the utility model fully considers the compatibility problem of buses and trucks, and different types of trucks can be used.

S2, the utility model not only opens the disturbing hole on the upper side of the camera, but also designs the air duct between the disturbing hole and the front hole of the monitoring device, so that the air flow formed by the front-back pressure difference of the monitoring device flows more frequently through the air duct under different scenes. Under the condition that the air flows to a certain strength, an air curtain can be formed, so that negative pressure is not easy to generate on the leeward surface around the lens, and meanwhile, light foreign matters around the lens can be blown away.

S3, the flange plate is arranged, and the FPC heating film material is glued, so that the excellent heat conduction performance of the aluminum alloy material is fully utilized, and the heating is faster.

See the prior art for further content.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
