Description

Technical Field

[0001] The utility model relates to the technical field of display, in particular to a vehicle taillight capable of displaying patterns on a curved surface. Background Art

[0002] As an important part of vehicle safety and personalized design, the functions and technical requirements of taillights are constantly improving. Traditional taillights mainly use incandescent lamps or LED light sources, with single functions, and can only transmit simple signal information such as braking and turning by turning on, off or flashing. This design gradually exposes its limitations in complex and changing traffic environments and cannot meet the safety, personalization and intelligence requirements of modern cars.

[0003] At present, with the rapid development of the automobile industry, taillights that can display patterns have appeared on the market. Such taillights can display dynamic graphics. For example, they can present customized patterns such as turn indicators, welcome animations, warning symbols, etc. through dynamic programming to meet the needs of modern automobiles for safety, personalization and intelligence.

[0004] Generally speaking, in order to conform to the streamlined shape of the car, the outer surface of the taillight is a curved surface. In order to make the pattern displayed by the taillight conform to this curved surface, some people propose to use flexible OLED (organic light-emitting diode) to make such taillights. However, due to the problems of low brightness and easy damage of OLED, only expandable curved surfaces can be formed by bending OLED, while the outer surface of most taillights is non-expandable curved surface. Therefore, the shape design of the taillight using OLED is limited, and it is difficult to meet the design requirements of various shapes of car taillights. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a taillight capable of displaying patterns on a curved surface. The taillight can not only display patterns on a curved surface, but also has a non-developable curved surface on its outer surface, which can meet the design of various shapes of taillights and has an anti-collision function. The technical solution adopted is as follows:

[0006] A vehicle taillight capable of displaying patterns on a curved surface, comprising a lamp housing, a light source module and a light guide, wherein the light source module and the light guide are both mounted on the lamp housing, and the light guide is located at the front side of the light source module, and is characterized in that: the light source module adopts an LED array display panel, and the LED array display panel is provided with an LED array composed of a plurality of LED pixels; the light guide is formed by arranging a large number of optical fibers, and there are gaps between adjacent optical fibers, and the rear ends of each optical fiber are respectively coupled with the corresponding LED pixels of the LED array display panel to form a light guide, and the front ends of each optical fiber constitute the front side surface of the light guide, and the front side surface of the light guide is a non-developable curved surface; and an optical fiber fixing component for fixing the middle section or the rear section of each optical fiber is provided on the lamp housing.

[0007] The non-developable surfaces refer to those surfaces that cannot be accurately developed into planes through geometric construction methods, such as surfaces with convexities or concavities, spherical surfaces, and wavy surfaces.

[0008] The light-guiding coupling means that the rear end of each optical fiber is designed to effectively receive the light emitted by the corresponding LED pixel on the LED array display board. Specifically, the rear end of each optical fiber can be aligned with the corresponding LED pixel position on the LED array display board to achieve light-guiding coupling.

[0009] In the structure of this taillight, the light source module adopts an LED array display board, and the LED can achieve high-brightness light emission, which meets the brightness requirements of the rear taillight of the car; by arranging a light guide portion formed by a large number of optical fibers on the front side of the LED array display board, since the optical fibers in the light guide portion have a light guiding function, the LED pattern presented by the LED array display board can be guided by each optical fiber to form a display pattern on the front side of the light guide portion, and since the front side of the light guide portion is a non-developable curved surface, a curved display pattern can be realized on the curved surface outside the exterior lamp, and various shapes of taillight designs can be met, and this taillight has an anti-collision function. When it is collided, the optical fiber and the optical fiber fixing component can play a certain buffering role to prevent damage to the expensive LED array display board.

[0010] As a preferred solution of the utility model, the optical fiber fixing component includes an optical fiber fixing plate, on which a plurality of positioning through holes are formed, and the middle section or the rear section of each optical fiber is fixed in the corresponding positioning through hole.

[0011] As a further preferred solution of the utility model, the optical fiber fixing plate is made of foaming material, thereby enabling the optical fiber fixing component to have a better buffering effect.

[0012] As a further preferred embodiment of the present invention, the foaming material is foam cotton or foam rubber.

[0013] As a preferred solution of the utility model, the LED pixels include LEDs of three colors, RGB, so that the taillight can display color patterns on a curved surface.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] (1) This type of taillight adopts an LED array display panel, and the LED can achieve high brightness, meeting the brightness requirements of the rear taillight of the car. By arranging a light guide composed of a large number of optical fibers on the front side of the LED array display panel, the LED pattern presented by the LED array display panel can be guided by each optical fiber to form a display pattern on the front side of the light guide portion. Since the front side of the light guide portion is a non-developable curved surface, a curved display pattern can be achieved, and the design of various shapes of taillights can be met;

[0016] (2) This type of taillight has an anti-collision function. When it is hit, the optical fiber and the optical fiber fixing component can play a certain buffering role to prevent damage to the expensive LED array display panel. BRIEF DESCRIPTION OF THE DRAWINGS
