Problems solved by technology

The problem is that a single lens basically cannot reach a wide angle of 170 degrees. Even if it reaches 170 degrees, the picture will be seriously deformed, which will affect the clarity of the picture.
[0003] In addition, the existing lens does not have the function of actively avoiding light, that is, when the light of the vehicle in front is facing the lens at night, the clarity of the picture will be reduced

Abstract

The invention discloses an angle-adjustable lens and an automobile data recorder. The angle-adjustable lens comprises a circular front lens and a back lens and further comprises a casing and a lens accommodation chamber arranged in the casing, wherein an angle of the front lens or the back lens in the lens accommodation chamber can be adjusted, and a transparent liquid medium is filled between the front lens and the back lens. Through the multi-functional angle-adjustable lens, visual lines can be changed through adjusting an included angle between the front lens and the back lens, and angle images which can not be captured in the prior art can be captured by an image sensor. The automobile data recorder is advantaged in that mounting a device capable of automatically adjusting an angle of the automobile data recorder is not required, and the lens angle can be automatically adjusted through the lens on the automobile data recorder.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an angle-adjustable lens and a driving recorder capable of actively adjusting the angle of view. Background technique [0002] Drive recorder is the instrument of the relevent informations such as image and sound in registration of vehicle traveling way. Driving recording is installed After instrument, the video image and sound of running car overall process can be recorded, evidence can be provided for traffic accident. The basic composition of a driving recorder generally includes devices such as a microprocessor, a data memory, a real-time clock, a display, a lens module, operation keys, a printer, and a data communication port. There are several general shooting angles of existing driving recorders, most of which are adjusted according to the angle of the camera: 90 degrees, 100 degrees, 120 degrees, 140 degrees, 150 degrees, 170 degrees, etc. The mainstream single-lens dr...
