Detailed Description

In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

As shown in fig. 1 to 5, in the present embodiment, there is provided a retro-reflector in which reflective particles are provided on an inner housing and a sensor is mounted, and the retro-reflector is mainly composed of a housing 5, an outer housing 1, an inner housing 4, and the like, and the body parts of the housing 5, the outer housing 1, and the inner housing 4 are in a cambered shape to expand the reflective range. Wherein, outer lamp shade 1 sets up in the casing 5 outside, and specific outer lamp shade 1 comprises the black piece 3 of inlayer and outer transparent piece 2, and transparent piece 2 is used for printing opacity and plays the inside effect that is difficult to dirty of protection, and black piece 3 and casing 5 outside welded fastening adopts black piece 3 can improve welded fastness.

Meanwhile, the inner lampshade 4 is welded on the inner wall of the shell 5, densely-distributed reflective particles are arranged on the inner lampshade 4, and the light-transmitting ports 30 corresponding to the inner lampshade 4 are formed in the black sheet 3 so that light passes through, the spacing distance between the inner lampshade 4 and the transparent sheet 2 is preferably 15mm, and of course, the spacing distance can be increased or reduced by adjusting the cavity depth of the shell 5 and the position of the inner lampshade 4 according to actual needs, so that the inner safety of the damaged outer lampshade 1 can be effectively ensured, and the inner lampshade 4 is better protected.

In order to facilitate the installation of functional components such as sensors, a mounting frame 52 is formed on the inner side of one end of the shell 5, a square opening 520 is formed on the mounting frame 52, and the sensors can be conveniently and directly installed through the design of the square opening 520, so that corresponding services are provided for drivers and passengers in the vehicle, convenience is brought to the running of the vehicle, and the safety coefficient is improved.

In order to prevent the problems of expansion due to heat and contraction due to the airtight structure, the top of the shell 5 is provided with an air vent 500. Of course, a limit opening 50 is formed around the outer side of the ventilation hole 500, and a ventilation film 51 is adhered to the inner area of the limit opening 50, and the ventilation film 51 just covers the ventilation hole 500, so that ventilation effect can be achieved, and dust prevention and pollution prevention can be completed.

Because the reflective particles of the conventional retro-reflector are on the outer globe, once the outer globe is damaged, the function of reverting signals to surrounding vehicles and pedestrians is no longer provided. Therefore, in the present embodiment, the reflective particles are designed on the inner globe 4, and the inner globe 4 is welded and embedded in the housing 5, and a safe distance of 15mm is maintained between the outer globe 1, so that the function of returning signals to surrounding vehicles and pedestrians can be maintained even after only the outer globe 1 is damaged due to collision. In addition, the sensor can be installed, radar, a camera and the like can be installed, the use requirement can be directly met, the later installation is not needed, and great convenience is brought to vehicle running.

Referring to fig. 5, the working principle of the present embodiment in use is: the incident light 6 irradiates the transparent sheet 2 reaching the outer lampshade 1, enters the inside of the shell 5 through refraction of the transparent sheet 2 to form a refracted light 7, the refracted light 7 is then irradiated to reflective particles on the inner lampshade 4, the reflective particles reflect the reflected light to form a reflected light 8, the reflected light 8 is then transmitted back to the transparent sheet 2, and then the refracted light 9 is formed through refraction of the transparent sheet 2, and the refracted light 9 is emitted to reach the human eyes 10, so that the function of providing a return signal for surrounding vehicles and pedestrians is finally completed.
