Embodiment Construction

[0023] see figure 1 and figure 2 , The present invention relates to a laser projector for vehicles, comprising a housing, a laser emitter 4 is installed in the housing, one end of the housing is open, and the emitting end of the laser emitter points to the opening.

[0024] Install the laser projector at the rear of the car. When the car is reversing, the laser projector works and the laser shines to the rear. If there is an obstacle behind the car, the laser will shine on the obstacle, and the driver can pass through the obstacle. Laser points, so as to determine the distance of obstacles, facilitate people's reverse parking, ensure the safety of vehicles, and prevent accidents.

[0025] The inventor considers that if the obstacle is too small, the laser emitted by the laser projector may not irradiate the obstacle, which will cause the driver to be unable to discover the obstacles behind.

[0026] A scattering lens group 6 is installed in the housing, the scattering lens ...

Abstract

The invention relates to a laser projector for reversing, which comprises a housing, wherein a laser transmitter is mounted in the housing; an opening is formed at one end of the housing; a transmitting end of the laser transmitter points to the opening; a scattering lens set is mounted in the housing, and comprises two convex lenses; the two convex lenses are arranged at the front and the rear; and the scattering lens set is located between the opening and the transmitting end of the laser transmitter. The laser projector is provided with the laser transmitter, the laser transmitter transmits laser backwards, the laser irradiates a rear barrier in a reversing process of an automobile, and a driver can judge a distance between the automobile and the barrier via an irradiation point of the laser, so that safe reversing is achieved.

Description

technical field [0001] The invention relates to a laser projector for reversing, which is mainly used in the field of automobiles. Background technique [0002] At present, the rear of the car mostly uses radar to detect obstacles, or uses reversing images to provide video images behind the driver. However, due to factors such as cost and the number of radars, there will be radar blind spots behind the car, which cannot effectively improve the safety of reversing. Although the reversing image can provide a better view during the day, the visibility of distant objects at night is low. Unable to satisfy the safety of backing up around the clock. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a laser projector for reversing, which can provide effective assistance for the reversing process of the car and ensure the safety of reversing the car. [0004] The technical scheme adopted in the present invention: ...
