Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to an automobile luminous signboard and an installation structure of the automobile luminous signboard. Background Art

[0002] Traditional car signs do not have the luminous function. When driving in low light conditions, the signs cannot be seen clearly and the brand of the vehicle cannot be identified. Therefore, signs with luminous functions have appeared on the market. Some luminous signs directly emit light from the car logo pattern; some luminous signs form an aperture at the edge of the car logo pattern to illuminate the sign.

[0003] The commonly used structure of existing automotive luminous signs is: outer lens + inner lens or light-distributing sheet + luminous module + base. This type of luminous sign requires welding or gluing and sealing, with many steps and troublesome assembly. When the luminous sign is installed on the body, the sign is at least 30 mm higher than the mating surface of the body, the thickness is too high, and the appearance is poor. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a thin, aesthetically pleasing, simple to assemble, low-cost automobile luminous sign and an installation structure for the automobile luminous sign.

[0005] The technical solution adopted by the present invention to solve the technical problem is to provide a car luminous sign, including:

[0006] A light blocking member and a base with a mounting cavity, wherein the base is provided with a light shielding portion and a light guiding portion, the light blocking member is arranged on the light guiding portion, and the light guiding portion forms a light-transmitting area outside the light blocking member;

[0007] A PCB board is arranged in the installation cavity. A plurality of light sources are arranged on the PCB board. Light emitted by the light sources can be emitted from the light-transmitting area through the light-guiding portion.

[0008] Furthermore, the base has a protrusion protruding toward a side away from the light blocking member, the installation cavity includes a groove, and the groove is opened on the protrusion, and the PCB board is located in the groove.

[0009] Further, the groove includes a first groove section provided on the light guide portion and a second groove section provided on the light shielding portion, the PCB board is arranged in the second groove section, and the light source is arranged in the first groove section;

[0010] The light shielding portion can reflect the light transmitted from the light source to the light guiding portion to the light transmitting area.

[0011] Furthermore, it also includes a sealing member; a mounting tube protrudes from the light shielding portion toward a side away from the light guiding portion, and the sealing member is arranged at an end of the mounting tube away from the light shielding portion.

[0012] Furthermore, the sealing member is a self-sealing wiring harness plug, which includes a plurality of wiring harnesses, and the wiring harnesses are electrically connected to the PCB board.

[0013] Furthermore, the light blocking member is bonded to the light guiding portion, and the PCB board is fixedly connected to the base.

[0014] Furthermore, the light guiding part and the light shielding part on the base are formed by two-color injection molding.

[0015] The technical solution adopted by the present invention to solve the technical problem is to provide a mounting structure for a car luminous sign, comprising:

[0016] The above-mentioned illuminated vehicle signs;

[0017] The vehicle body is provided with a recessed portion; the base is fixedly connected to the vehicle body, and the protrusion is located in the recessed portion.

[0018] Furthermore, the distance between the light blocking member and the vehicle body is less than or equal to 10 mm.

[0019] Furthermore, the base is bonded to the vehicle body, or the base is snap-connected to the vehicle body.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the present invention, the outer lens and inner lens (or light-distributing sheet) in the existing luminous sign are eliminated, and an integrated base is set, which effectively reduces the thickness of the luminous sign itself, and a protrusion is set on the base to match the recessed part on the vehicle body. After the luminous sign is assembled on the vehicle body, it can be ensured that the height of the luminous sign protruding from the vehicle body is less than 10 mm (that is, the distance between the light-blocking part and the vehicle body is less than 10 mm), and the appearance is high; a groove is set on the protrusion, and the PCB board is accommodated in the groove, and the light source is in the first groove section of the groove, adjacent to the light guide part, which not only makes the structure more compact to fully reduce the thickness of the luminous sign, but also the luminous light source is adjacent to the light guide part, and the light shielding part can also reflect the light transmitted by the luminous light source to the light guide part to the light-transmitting area, ensuring the utilization rate of light, so that the luminous effect of the luminous sign is good. On the other hand, the base is set as an integral type, and does not need to be welded or sealed for assembly. It only needs to install a self-sealing harness plug on the installation tube, which can simplify the assembly process and reduce manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] like Figure 1-Figure 3 As shown, a car luminous sign includes: a light blocking member 1, a base 2, a PCB board 3 and a sealing member 4.

[0038] A light blocking member 1 and a base 2 with a mounting cavity 20, wherein a light shading portion 21 and a light guiding portion 22 are provided on the base 2, wherein the light blocking member 1 is arranged on the light guiding portion 22, and the light guiding portion 22 forms a light-transmitting area 23 outside the light blocking member 1; it should be noted that since the size of the light blocking member 1 is smaller than the size of the light guiding portion 22, after the light blocking member 1 is arranged on the light guiding portion 22, the light guiding portion 22 cannot be completely blocked, thereby forming the light-transmitting area 23. In this scheme, the light-transmitting area 23 is arranged in a ring shape, that is, the luminous sign only needs to emit light in a circle. In order to distinguish the light guiding portion 22 from the light shading portion 21, their section lines are distinguished in the accompanying drawings. In fact, the light guiding portion 22 and the light shading portion 21 are integrated, both are part of the base 2, and are integrally two-color injection molded, that is, the light guiding portion 22 and the light shading portion 21 on the base 2 are two-color injection molded. The PCB board 3 is arranged in the installation cavity 20. The PCB board 3 is provided with a plurality of light sources 30. The light emitted by the light source 30 can be emitted from the light-transmitting area 23 through the light-guiding portion 22, i.e., a circumferential light-emitting effect. The light-shielding portion 21 can also reflect the light transmitted from the light source 30 to the light-guiding portion 22 to the light-transmitting area 23, thereby ensuring the utilization rate of light. The light source 30 is preferably an LED lamp. Specifically, the light-blocking member 1 is bonded to the light-guiding portion 22, the PCB board 3 is fixedly connected to the base 2, and the PCB board 3 can be fixed to the base 2 by screws or the PCB board 3 is snap-connected to the base 2.

[0039] like Figure 2-Figure 3As shown, the base 2 has a protrusion 24 protruding from one side away from the light blocking member 1, the installation cavity 20 includes a groove 240, and the groove 240 is arranged on the protrusion 24, and the PCB board 3 is located in the groove 240. It should be explained that the groove 240 is a part of the installation cavity 20. Specifically, the groove 240 includes a first groove section 240A arranged on the light guiding portion 22 and a second groove section 240B arranged on the light shielding portion 21, and the first groove section 240A and the second groove section 240B are connected to each other. Among them, the PCB board 3 is arranged in the second groove section 240B, and the light emitting light source 30 is arranged in the first groove section 240A, which can further improve the compactness of the light-emitting sign.

[0040] During actual use, a groove 240 is provided on the protrusion 24, the PCB board 3 is accommodated in the groove 240, and the light source 30 is in the first groove section 240A of the groove 240, adjacent to the light guide part 22, which not only makes the structure more compact to fully reduce the thickness of the luminous sign, but also the light source 30 is adjacent to the light guide part 22 to achieve a good lighting effect.

[0041] Preferably, the luminous sign also includes a seal 4; a mounting tube 25 protrudes from the shading portion 21 on a side away from the light-guiding portion 22, and the seal 4 is arranged at one end of the mounting tube 25 away from the shading portion 21. The seal 4 is a self-sealing harness plug, including a plurality of harnesses (not marked in the figure), and the harness is electrically connected to the PCB board 3, which is convenient for wiring and assembly, and no additional wires are required. This solution is configured as an integral base 2, which does not require welding or sealing for assembly. It only needs to install a self-sealing harness plug on the mounting tube 25, which can simplify the assembly process and reduce manufacturing costs.

[0042] like Figure 4 As shown, the installation structure of the automobile luminous sign of the present solution, wherein the installation structure of the automobile luminous sign includes: the above-mentioned automobile luminous sign; and also includes a vehicle body 5, on which a recessed portion 50 is provided; the base 2 is fixedly connected to the vehicle body 5, and the protrusion 24 is in the recessed portion 50. Specifically, the spacing between the light blocking member 1 and the vehicle body 5 is less than or equal to 10 mm. In the present solution, the protruding height of the luminous sign can be controlled to be about 6 mm, the thickness is reduced, and the appearance is high. The base 2 is bonded to the vehicle body 5, or the base 2 is snap-connected to the vehicle body 5. The snap-on structure is not shown in the figure. The vehicle body 5 can be a grille, or a door of a car trunk, or other parts.

[0043] In actual use, the present automobile luminous sign eliminates the outer lens and inner lens (or light-distributing sheet) in the existing luminous sign, and is provided with an integrated base 2, which effectively reduces the thickness of the luminous sign itself, and a protrusion 24 is provided on the base 2, which is adapted to the recessed portion 50 on the vehicle body 5. After the luminous sign is assembled on the vehicle body 5, it can be ensured that the height of the luminous sign protruding from the vehicle body 5 is less than 10 mm (that is, the distance between the light blocking member 1 and the vehicle body 5 is less than 10 mm), and the appearance is high.

[0044] In this solution, the luminous sign is thin in thickness, highly aesthetic, and is easy to assemble and low in cost.

[0045] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
