Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of reflective warning devices in the automotive industry, specifically a retroreflector comprising two lenses. Background Technology
[0002] With the rapid development of intelligent electric vehicles, customers have increasingly higher demands for car exterior styling. Designing more aesthetically pleasing, fashionable, and unique designs is a crucial factor for automakers to win in the market. Among exterior design components, lighting fixtures are undoubtedly the most eye-catching and versatile. As a lighting system, lighting fixtures must meet legal and regulatory requirements and have high safety standards while maintaining a stylish and attractive appearance, which to some extent limits their development. Retroreflectors, as a type of lighting fixture, have a relatively simple structure, but their importance cannot be ignored. To ensure the safety of vehicles driving at night, various motor vehicles are equipped with retroreflectors on their sides and rear. When light shines on a retroreflector, it reflects the incoming light back. The retroreflector on the vehicle in front can provide a warning to vehicles behind, allowing drivers behind to take appropriate measures in time to ensure driving safety. Retroreflectors are an important safety guarantee for motor vehicles driving at night.
[0003] As cars become increasingly intelligent, driverless cars are gradually appearing before the public. When these driverless cars achieve bidirectional driving, the current retroreflectors are monochromatic and cannot meet the requirements.
[0004] To address this problem, a retroreflector comprising two lenses is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a retroreflector comprising two optical lenses to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a retroreflector comprising two light distribution lenses, including a black lamp body, a gear-shaped rotating structure fixed to the left end of the black lamp body, a pin-shaped rotating structure fixed to the right side of the black lamp body, a first light distribution lens fixed to the lower end of the black lamp body, and a second light distribution lens fixed to the upper end of the black lamp body, wherein the first light distribution lens is a red light distribution lens.
[0007] Preferably, the second lens is an amber lens.
[0008] Preferably, the second lens is a black lens.
[0009] Preferably, both the first and second optical lenses are connected and fixed to the black lamp body by ultrasonic welding.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] The retroreflector in this invention uses dual light-distributing mirrors, and is divided into two types. One type is installed at the front or rear of the vehicle. One side of the dual light-distributing mirror of this retroreflector is a transparent red light-distributing mirror with a retroreflective pattern, and the other side is a black light-distributing mirror without a retroreflective pattern. The other type is installed on the side of the front or rear of the vehicle. One side of the dual light-distributing mirror of this retroreflector is a transparent red light-distributing mirror with a retroreflective pattern, and the other side is an amber light-distributing mirror with the same retroreflective pattern. The two light-distributing mirrors of both types of retroreflectors are ultrasonically welded to both sides of the lamp body, which not only makes installation convenient, but also greatly improves the safety of vehicle driving.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0020] Example:
[0021] Please see Figure 1-5 This utility model provides a technical solution:
[0022] A retroreflector comprising two light-distributing lenses includes a black lamp body 1, a gear-shaped rotating structure 2 fixed to the left end of the black lamp body 1, a pin-shaped rotating structure 3 fixed to the right side of the black lamp body 1, a first light-distributing lens 4 fixed to the lower end of the black lamp body 1, and a second light-distributing lens 5 fixed to the upper end of the black lamp body 1. The first light-distributing lens 4 is a red light-distributing lens.
[0023] The second lens 5 is an amber-colored lens.
[0024] The second lens 5 is a black lens.
[0025] The first lens 4 and the second lens 5 are both connected and fixed to the black lamp body 1 by ultrasonic welding.
[0026] The retroreflector uses dual reflectors and is divided into two types. One type is installed at the front or rear of the car. One side of the reflector is a transparent red reflector with a retroreflective pattern, and the other side is a black reflector without a retroreflective pattern. The other type is installed on the sides of the front and rear of the car. One side of the reflector is a transparent red reflector with a retroreflective pattern, and the other side is an amber reflector with the same retroreflective pattern. Both types of reflectors have their two reflectors ultrasonically welded to both sides of the black lamp body 1. Both types of reflectors have a gear-shaped rotating structure 2 on the left end and a pin-shaped rotating structure 3 on the right end. When the bidirectional autonomous vehicle is sold domestically, four reflectors are installed on one vehicle, one on each side of the front of the car and one on each side of the rear of the car. When the vehicle is exported to North America, in addition to the above four reflectors, four additional side reflectors need to be installed, one on each side of the front of the car and one on each side of the rear of the car. Furthermore, the two lenses of the four retroreflectors are a combination of red and amber.
[0027] When the car is moving forward, the rear and rear-side retroreflectors appear red to reflect light from vehicles behind, ensuring driving safety. The front retroreflector, through a rotating mechanism at both ends, appears non-reflective black, while the front side retroreflectors appear amber. When the autonomous vehicle changes direction, the rear becomes the front, the rear retroreflector changes from red to black, and the rear side retroreflectors change from red to amber; conversely, the front becomes the rear, the front retroreflector changes from non-reflective black to reflective red, and the front side retroreflectors change from amber to red. When this bidirectional autonomous vehicle switches directions, the front and rear retroreflectors, as well as the side retroreflectors, can switch back and forth to meet regulatory requirements and ensure safe driving on the road.
[0028] The installation steps are as follows:
[0029] The first optical lens 4 is ultrasonically welded to the black lamp body 1, rotated 180 degrees, and then the black or amber optical lens is ultrasonically welded to the other side of the black lamp body 1. The left end of the retroreflector is a gear-shaped rotating structure 2, and the right end is a pin-shaped rotating structure 3. When installing the retroreflector, the right pin-shaped rotating structure 3 is inserted into the matching part, and the left gear-shaped rotating structure 2 is engaged with the gear of the matching part. Then, a motor drives it to rotate 180 degrees, which can switch the two different optical lenses of the retroreflector.

It is obvious to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
