Automobile auxiliary driving system camera demisting device

Abstract

The embodiment of the invention discloses an automobile auxiliary driving system camera demisting device. The device comprises a shell, a camera, a fan, a heater and a control circuit, wherein the camera, the fan, the heater and the control circuit are arranged in the shell. The shell comprises a pasting part for fixing the shell to a front windshield of an automobile. An air hood is composed of agroove formed in the side, provided with the pasting part, of the shell and the front windshield. An air outlet is located in one side of the air hood. An air inlet is formed in the groove. The fan is arranged next to the air inlet. The heater is arranged between the fan and the air inlet. The camera for shooting images outside the front windshield extends to the groove from the inner portion ofthe shell. The control circuit is connected with the fan and the heater so as to control the fan and the heater to be started or stopped and start or stop the demisting function of the camera. By theadoption of the technical scheme, mist on the auxiliary driving camera can be conveniently and quickly removed when an image imaging effect is guaranteed, and the driving experience of a driver is enhanced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of in-vehicle devices, and in particular, to a camera defogging device for an automobile auxiliary driving system. Background technique [0002] Because the assisted driving camera of the car can ensure the legitimate rights and interests of the driver during the driving process by recording the video information during the driving process, supervise the driving behavior of the driver and record the scenery along the way, it is very popular among car owners. [0003] Usually, the assisted driving camera is installed on the front windshield of the car. Due to the influence of environmental factors, when the front windshield of the cab is fogged, it will affect the normal operation of the assisted driving camera. In the prior art, the assisted driving camera is usually defogged by means of a warm air defogging system built in the car or by manually spraying and maintaining an anti-fogging...

Problems solved by technology

[0004] However, when the camera is installed near a corner or surrounded by obstacles, such as figure 1 As shown, the camera device of the car auxiliary driving system has a groove. After pasting it on the front windshield of the car, a cavity area with a small opening and a large inner cavity will be formed, which will make the air circulation poor and the defogging time will be greatly extended. ;The maintenance anti-fog coating is difficult to determine its effective duration due to the different use environments. At the same time, in order to ensure the image imaging effect, it is necessary to spray and maintain the anti-fog coating frequently, which is not convenient for actual use.
