[0027] The core of the utility model is to disclose a reflective structure, a lamp and a vehicle to reduce the difficulty of assembling lamps in multiple light-emitting areas and optimize the light-emitting effect thereof.

[0028] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0029] See also Figure 2-7The reflective structure provided by the embodiment of the utility model mainly includes a reflective member 10 and a circuit board 20, wherein at least two reflective areas are arranged at intervals on the reflective member 10, and a single reflective area specifically includes a light inlet 110 and a reflective surface 120. The light inlet 110 is arranged toward the reflective surface 120 so that light passes through from one side and reaches the reflective surface 120, and the reflective surface 120 is designed as an arc structure to meet the reflection requirements, and at the same time, the structural edge of the light inlet 110 is fixedly connected to an edge of the reflective surface 120, so that most of the light passing through the light inlet 110 can reach the reflective surface 120. On this basis, the circuit board 20 is fixedly arranged on the reflective element 10 and corresponds to the reflective area one by one. Specifically, the light-emitting area of ​​each circuit board 20 is arranged toward a single reflective surface 120 through a light inlet 110, and preferably, a plurality of circuit boards 20 are arranged in parallel and at intervals, so that the light emission of adjacent circuit boards 20 does not affect each other, and the light can be efficiently reflected, thereby enhancing the concentration and reflection effect of the light. In addition, the parallel arrangement of the circuit boards 20 also helps to evenly distribute the light, avoiding the phenomenon that multiple light-emitting areas are locally too bright or too dark when coordinated.

[0030] On the basis of the above structure, adjacent reflective areas are designed as an integrated structure. It does not need to be fixedly connected by other structural parts as in the prior art, and its assembly difficulty is low. At the same time, the preset assembly angle can also be pre-realized by the mold, which reduces the error in the assembly process. Therefore, the main assembly process of the reflective structure only needs to realize the assembly of the circuit board 20 on the reflective member 10, and it can be connected by bonding, clamping or bolting. Compared with the prior art, the assembly process saves steps and reduces the difficulty of assembly. In addition, the parallelism of the circuit board 20 can also be achieved by the corresponding fixed structure on the reflective member 10. The operator only needs to connect it without subjectively judging the parallelism of the circuit board 20. It can also improve the convenience of assembly and reduce the assembly error under subjective judgment.

[0031] The reflective structure provided by the embodiment of the utility model is provided with at least two reflective areas on a single reflective member 10, and each reflective area is provided with a circuit board 20, the circuit board 20 is fixedly provided on the reflective member 10, and irradiates the reflective surface 120 of the arc-shaped structure through the light inlet 110 on each reflective area, so as to achieve the purpose of realizing multiple light-emitting areas on a single reflective member. At the same time, compared with the prior art, it does not need to connect different light-emitting areas through components, which reduces the difficulty of assembling the reflective structure. In order to realize the parallel setting of the reflective plate, a fixed structure can be pre-arranged on the reflective member 10 and calibrated, so that the circuit board 20 can be connected to the reflective member 10 without artificially calibrating its parallelism, thereby avoiding the subjective judgment deviation on the parallelism of the circuit board 20, and achieving more uniform light distribution in multiple light-emitting areas, thereby improving the luminous effect of the reflective structure.

[0032] It should be noted that in the reflective structure provided in the embodiment of the present invention, two or more reflective areas can be set on a single reflective element 10 to meet the needs. Similarly, in some embodiments of the present invention, only two reflective areas can be set on a single reflective element 10, and a connecting structure can be set on the opposite sides of the reflective element 10 to connect two adjacent reflective elements 10, thereby realizing an extended design of the reflective area. The number of reflective elements 10 can be selected as needed, further improving the degree of commonality during the use of the reflective element 10.

[0033] Furthermore, in the reflective structure provided in the embodiment of the utility model, in order to effectively fix the circuit board 20, a top rib 130 and a fixing portion are further provided on the reflective member 10. The top rib 130 is arranged between two adjacent reflective areas, and one side thereof is in contact with the arc-shaped outer wall of a single reflective surface 120. It should be noted that the outer wall of the reflective surface 120 here specifically refers to the structural wall surface that does not reflect light. The top rib 130 is designed to clamp and limit one side of the circuit board 20 through a protruding structure, and the fixing portion can be bonded, clamped or threaded to fix the circuit board 20 from another point, so that the circuit board 20 can achieve a stable position setting through two-point connection, thereby ensuring the stability and fixation of the circuit board 20 on the reflective member 10. The above structural design not only improves the overall rigidity of the reflective structure and reduces the difficulty of assembly, but also helps to reduce the vibration and displacement of the circuit board 20 during installation or use, thereby improving the consistency and reliability of the reflective effect.

[0034] Furthermore, in order to make the design of the reflective structure more compact and reduce the space occupied by the reflective result, the single circuit board 20 provided in the embodiment of the utility model corresponds to a single top rib 130. At the same time, the first side of the circuit board 20 is interference fit into the gap between the top rib 130 and the side wall of the light entrance 110, and one end of the circuit board 20 abuts the reflective element 10. In the above structure, the circuit board 20 is not only limited and fixed by the structure of the top rib 130 and the light entrance 110, but also the adjacent light entrance 110, that is, the structure of the reflection area is more compact. At the same time, the first side of the circuit board 20 is wrapped and limited in three directions, so that the connection of the circuit board 20 is tighter and more stable, reducing the problem of unstable reflective effect caused by loose connection. At the same time, the above structure also facilitates the installation and disassembly of the circuit board 20, thereby improving the convenience of maintenance.

[0035] In order to further improve the structural stability of the reflective structure after assembly, in some embodiments of the utility model, a raised portion 210 is further provided at the edge of the second side of the circuit board 20, and the raised portion 210 is fixedly engaged with the wiring harness clamp 220, and a raised shaft 140 is provided on the reflective member 10. It should be noted that the raised shaft 140 is preferably provided at the top of the arc-shaped area of ​​the reflecting surface 120 to maintain a maximum distance from the first side of the circuit board 20. At the same time, a thread is provided inside the raised shaft 140, and the opening of the raised shaft 140 is aligned with the connecting port on the wiring harness clamp 220 so that the wiring harness clamp 220 can be locked to the raised shaft 140 by means of the connecting bolt 150. The setting of the raised shaft 140 can realize a fixed connection between the opposite sides of the circuit board 20 and the top rib 130, thereby ensuring the connection strength of the circuit board 20 on the reflective member 10. In addition, the design of the raised shaft 140 and the connecting bolt 150 can also make the installation and disassembly of the circuit board 20 more convenient, and facilitate maintenance and replacement.

[0036] On the basis of the above embodiment, two wiring harness cards 220 may be spaced apart and connected to the second side of a single circuit board 20, and both wiring harness cards 220 are fixedly connected to the reflective element 10, that is, each wiring harness card 220 has a threaded raised shaft 140 for fixation. The structure of the two wiring harness cards 220 not only improves the fixing stability of the circuit board 20, but also reduces the stress concentration caused by improper fixation of the circuit board 20 through the spaced connection, thereby extending the service life of the circuit board 20. At the same time, the spaced connection design also helps to evenly distribute the weight of the circuit board 20 and reduce the uneven reflective effect caused by uneven weight.

[0037] Furthermore, in some embodiments of the present invention, the wiring harness card 220 is made of plastic material, which not only has good mechanical strength and heat resistance and insulation characteristics, but also has low cost and easy processing characteristics. The use of plastic wiring harness card 220 not only improves the overall economy of the reflective structure, but also enhances the safety of the circuit board 20 through its good insulation performance. In addition, the wiring harness card 220 made of plastic material is also easy to mold and dye. Wire harness cards 220 of different shapes and colors can be produced according to different design requirements to improve the aesthetics of the reflective structure, or to distinguish the lighting requirements and importance of different circuit boards 20 through different color markings.

[0038] In order to further optimize the assembly effect of the circuit board 20, in some embodiments of the present invention, a guide portion 1310 is further provided on the top rib 130. The guide portion 1310 is a chamfered or rounded structure, and its guiding direction is the insertion direction of the circuit board 20. The setting structure of the guide portion 1310 can not only improve the guiding accuracy during the insertion of the circuit board 20, but also reduce the friction and damage during the insertion process of the circuit board 20 through the chamfered or rounded structure. In addition, the design of the guide portion 1310 also helps to improve the installation efficiency of the circuit board 20 and reduce the time and labor cost during the installation process.

[0039] In addition, in order to enhance the reflection effect of the reflective surface 120 on the light emitted by the circuit board 20, in some embodiments of the present invention, the light entrance 110 is designed as a rectangular structure, and the circuit board 20 completely covers the light entrance 110, which not only improves the overall aesthetics of the reflective structure, but also enhances the sealing of the light entrance 110 through the complete coverage of the circuit board 20, so that the outgoing light of the circuit board 20 can pass through the entire area of ​​the light entrance 110 and reach the position of the reflective surface 120, thereby ensuring the reflection effect and lighting effect of the light.

[0040] Furthermore, an embodiment of the utility model also provides a lamp, which includes the reflective structure provided by any of the above embodiments, so that the lamp can not only meet the application scenarios of multiple light-emitting areas, but also improve the lighting effect and uniformity of the lamp through the optimization of the reflective structure; in addition, the reflective structure of the lamp can flexibly adjust the number and layout of the reflective areas according to different lighting needs, thereby achieving more precise and efficient lighting effects.

[0041] Furthermore, an embodiment of the utility model also provides a vehicle, which includes at least one lamp provided by the above embodiment. It should be noted that since the lamp has the technical effects provided by the above embodiment, the vehicle also has the above technical effects, which will not be repeated herein.
