Abstract
Description
Technical Field
[0001] The utility model relates to a light-shielding structure for an automobile lamp. Background Art
[0002] As automobiles become increasingly streamlined, the demand for smaller and more refined lamps is increasing. This reduction in lamp size has led to increasingly smaller spacing between different lamp functions, or between different luminous surfaces within the same lamp. Currently, a concave-convex shading structure between two plastic parts is commonly used to prevent light crosstalk. First, the concave-convex shading structure is a combination of two plastic parts. Deviations in the processing or assembly of these parts can lead to light leakage, light crosstalk, dusting from vibration testing, and even breakage, placing high demands on the machining and assembly precision of the parts. Second, because the two plastic parts are combined, the overall size of the concave-convex shading structure exceeds 10mm, considering the effects of plastic molding and vibration. This contradicts the design principle of minimizing the lamp size.
[0003] In summary, the concave-convex shading structure not only has a poor shading effect and requires high manufacturing precision, but also occupies a large space, greatly limiting the customer's vehicle styling. Summary of the Invention
[0004] In view of the above problems, the present invention provides a light-shielding structure for an automobile lamp, which effectively solves the problems pointed out in the background art.
[0005] The technical solution adopted in this utility model is:
[0006] A car lamp shading structure includes a bracket, a rubber strip and a decorative frame. The rubber strip is located between the bracket and the decorative frame. The rubber strip is fixed to the bracket and has a protrusion at one end of the rubber strip facing the decorative frame. The decorative frame is fixed to the bracket by a fastening mechanism.
[0007] Preferably, the protrusion and the decorative frame abut against each other to form an interference fit.
[0008] Preferably, the rubber strip and the bracket are integrally formed.
[0009] Preferably, the bracket is provided with a groove matching the rubber strip, and the rubber strip is fixed to the bracket via the groove.
[0010] Preferably, the fastening mechanism is a buckle and a screw.
[0011] The utility model forms an interference fit structure between the protrusion on the rubber strip and the decorative frame, thereby achieving a 0-gap soft connection between the bracket and the decorative frame, thereby ensuring the shading effect. At the same time, such a structure occupies little space, and the protrusion can adopt a V-shaped structure, which can improve the sealing.
[0012] Preferably, it further includes a lamp housing, a lampshade, an LED module, a reflector and a thick wall. The bracket is fixed in the lamp housing, the lampshade is located on the outside of the decorative frame, the thick wall and the reflector are respectively arranged on the upper and lower sides of the bracket. The thick wall transmits the light emitted by the LED module to the upper area of the lampshade to form a first light-emitting surface, and the reflector transmits the light emitted by the LED module to the lower area of the lampshade to form a second light-emitting surface.
[0013] The beneficial effects of the utility model are as follows:
[0014] 1. The requirements for parts processing and assembly precision are low. Even if there is deviation, it can still ensure that there is no light leakage or light crosstalk, thus reducing manufacturing costs;
[0015] 2. The zero-gap soft connection between the bracket and the decorative frame avoids dust or breakage caused by friction between plastic parts due to manufacturing and assembly deviations;
[0016] 3. The overall size of the conventional concave-convex shading structure is more than 10 mm. Compared with the conventional concave-convex shading structure, the present invention occupies a smaller space, saving about half the space. In particular, when the rubber strip and the bracket are integrally formed, the space occupied is even smaller.
[0017] 4. The utility model transmits the light emitted by the LED module to the upper and lower areas of the lampshade through thick walls and reflectors respectively, and adopts a new shading structure for shading, which not only has a good shading effect, but also has low manufacturing precision requirements and occupies little space.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more, unless expressly limited otherwise.
[0025] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components.

[0027] The present invention will be described in further detail below through specific embodiments with reference to the accompanying drawings.
[0028] like Figure 1-3 As shown, a car lamp shading structure includes a bracket 1, a rubber strip 2 and a decorative frame 3. The rubber strip 2 is located between the bracket 1 and the decorative frame 3. The rubber strip 2 is fixed to the bracket 1, and the rubber strip 2 is provided with a protrusion 4 at one end facing the decorative frame 3. The decorative frame 3 is fixed to the bracket 1 by a fastening mechanism. The protrusion 4 and the decorative frame 3 are abutted against each other to form an interference fit. The fastening mechanism is a buckle and a screw.
[0029] As a preferred solution, the rubber strip 2 and the bracket 1 are integrally formed.
[0030] As another preferred solution, a groove 5 matching the rubber strip 2 is provided on the bracket 1 , and the rubber strip 2 is fixed to the bracket 1 via the groove 5 .
[0031] The present invention also includes a lamp housing 6, a lampshade 7, an LED module 8, a reflector 9 and a thick wall 10. The bracket 1 is fixed in the lamp housing 6, the lampshade 7 is located on the outside of the decorative frame 3, the thick wall 10 and the reflector 9 are respectively arranged on the upper and lower sides of the bracket 1, the thick wall 10 transmits the light emitted by the LED module 8 to the upper area of the lampshade 7, forming a first light-emitting surface 11, and the reflector 9 transmits the light emitted by the LED module 8 to the lower area of the lampshade 7, forming a second light-emitting surface 12.
[0032] The lighting principle of the lamp adopting the shading structure of the utility model is as follows:
[0033] The LED module 8 is a light source. The light emitted upward is conducted by the thick wall 10 and then emitted outward from the upper area of the lampshade 7, forming a first light-emitting surface 11 of the lampshade 7. The light emitted downward is reflected by the reflector 9 and then emitted outward from the lower area of the lampshade 7, forming a second light-emitting surface 12 of the lampshade 7.
[0034] The shading structure of the present invention utilizes the protrusion 4 of the rubber strip 2 and the decorative frame 3 to form a 0-gap soft connection, thereby avoiding dust or breakage caused by mutual friction between plastic parts due to manufacturing and assembly deviations. At the same time, compared with the conventional concave-convex shading structure, such a shading structure can greatly reduce the overall structure size and reduce space occupancy. At the same time, since there is no concave-convex structure to cooperate, the manufacturing precision can be reduced, thereby reducing production costs.
[0035] Finally, it should be noted that the above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and is subject to numerous variations. All variations that can be directly derived or conceived by a person of ordinary skill in the art from the disclosure of the present invention should be considered within the scope of protection of the present invention.
