[0040] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not impose any limitation on the content of the utility model described in the claims. Further, all the contents of the configurations shown in the following embodiments are not necessarily essential for the solution of the utility model described in the claims. It should be noted that for the sake of description, only the parts related to the relevant utility model are shown in the drawings. Without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.
[0041] Combined with Figures 1 - 10 , the flexible circuit board mounting assembly disclosed by the present utility model includes a mounting bracket and a reinforcing plate 200. The mounting bracket includes a mounting plate 100 and a limiting baffle 110. It is defined that the two opposite side surfaces of the mounting plate 100 are respectively a mounting surface and a light-emitting surface. The limiting baffle 110 is arranged on both sides of the mounting surface, and the flexible circuit board 300 is used to be arranged on the mounting surface. A light-emitting hole 101 for allowing the light-emitting elements on the flexible circuit board 300 to emit light is formed through the mounting plate 100. Elastic clamping portions 210 are arranged on both sides of the reinforcing plate 200. The elastic clamping portions 210 are in abutting cooperation with the limiting baffle 110, and the reinforcing plate 200 is used to press the flexible circuit board 300 against the mounting surface of the mounting plate 100.
[0042] During assembly, first paste the flexible circuit board 300 onto the reinforcing plate 200, then align the light-emitting components on the flexible circuit board 300 with the light-emitting holes 101, then install the reinforcing plate 200 along the guidance of the limiting baffle 110 onto the mounting surface, and finally install the mounting bracket into the lamp housing of the vehicle lamp to complete the assembly of the flexible circuit board 300 on the vehicle lamp.
[0043] Compared with the prior art, the flexible circuit mounting assembly disclosed by the utility model realizes the connection between the mounting bracket and the reinforcing plate 200 through the clamping of the elastic clamping portion 210 and the limiting baffle 110. The structure is simple, the installation is convenient, the cost is low, there is no need to open a plurality of connection holes on the reinforcing plate 200, and the setting of the limiting baffle 110 reduces the risk of the electronic components on the flexible circuit board 300 colliding with the surrounding components during the assembly process.
[0044] Further, in an embodiment, a guiding post 120 is arranged on the mounting surface, and a guiding hole 201 for the guiding post 120 to pass through is opened on the reinforcing plate 200. During assembly, after aligning the guiding hole 201 of the reinforcing plate 200 with the guiding post 120, it is then installed on the mounting surface along the guiding of the limiting baffle 110 and the guiding post 120.
[0045] Correspondingly, an avoidance hole corresponding to the guiding post 120 is opened on the flexible circuit board 300. The setting of the guiding post 120 further ensures the accuracy of the installation position of the flexible circuit board 300 on the mounting bracket.
[0046] In a further optimized solution, a barb structure 220 for clamping with the guiding post 120 is arranged on the guiding hole 201. The setting of the barb structure 220 can increase the connection reliability between the reinforcing plate 200 and the mounting bracket.
[0047] In an embodiment, the elastic clamping portions 210 are two groups and are respectively arranged at both ends of the reinforcing plate 200 to ensure reliable clamping with the mounting bracket.
[0048] In order to reduce production costs, combined with Figure 1 and Figure 10 , when the guiding post 120 is arranged on the mounting plate 100, the guiding post 120 and the limiting baffle 110 can be respectively arranged at both ends of the mounting plate 100 and arranged in a staggered manner. Correspondingly, the guiding hole 201 and the elastic clamping portion 210 are respectively arranged at both ends of the reinforcing plate 200. That is, in this embodiment, both ends of the reinforcing plate 200 are respectively clamped and fixed to the mounting bracket through the barb structure 220 and the elastic clamping portion 210. At the same time, there is no need to arrange the elastic clamping portion 210 and the limiting baffle 110 at the end of the reinforcing plate 200 where the barb structure 220 is arranged, thereby reducing costs.
[0049] According to the actual situation, the number of mounting plates 100 can be one or more. Figure 10A technical solution with two mounting plates 100 is shown. The actual number of mounting plates 100 can be adjusted according to the number of light-emitting components inside the actual vehicle lamp. A preset distance is provided between different mounting plates 100, and adjacent mounting plates 100 are connected by a support plate 140, and the support plate 140 is used to support and guide the flexible circuit board 300; there are multiple reinforcing plates 200 corresponding one by one to the mounting plates 100.
[0050] Among them, multiple mounting plates 100 can be arranged in parallel or at a certain angle. The spacing distances between different mounting plates 100 can be the same or different. The angle between the support plate 140 and the mounting plate 100 can be a right angle or an obtuse angle to avoid affecting the light emission of the light-emitting components.
[0051] The above-mentioned reinforcing plate 200 is usually made of metal. And since the reinforcing plate 200 is usually prepared by a stamping process, in order to avoid the processing defects such as burrs and flash at the edge position of the reinforcing plate 200 from affecting the flexible circuit board 300, each edge of the reinforcing plate 200 is turned over towards the direction away from the mounting surface to form a flanging 202, and the edge position of the reinforcing plate 200 after turning over is in a rounded corner transition.
[0052] The elastic clamping portion 210 and the barb structure 220 are integrally formed with the reinforcing plate 200 and are prepared by processes such as cutting and bending.
[0053] For a further optimized solution, taking the plate-shaped structure of the reinforcing plate 200 shown in Figure 4 as an example, avoiding notches 203 are provided at the four corners of the reinforcing plate 200. The setting of the avoiding notches 203 can reduce the probability of collision when the reinforcing plate 200 is installed on the mounting bracket.
[0054] The angle between the limiting baffle 110 and the mounting plate 100 is usually a right angle. In some embodiments, the angle between the limiting baffle 110 and the mounting plate 100 is an obtuse angle, so that the two limiting baffles 110 are arranged in an open-mouth manner, which is convenient for the elastic clamping portion 210 to be gradually clamped with the limiting baffle 110 during the process of installing the reinforcing plate 200 onto the mounting bracket.
[0055] Combined with Figure 6 , light condensing plates 130 are provided on both sides of the light-emitting surface. The light condensing plates 130 are made of a milky white material and can produce a light condensing effect. The installation angle between the light condensing plates 130 and the mounting plates 100 can be adjusted according to the actual situation.
[0056] In one embodiment, the limiting baffle 110 and the light condensing plate 130 are integrally formed. Further, the limiting baffle 110, the support plate 140, the guiding column 120, the light condensing plate 130 and the mounting plate 100 are all integrally formed and are made of plastic materials.
[0057] The headlight disclosed by the present utility model includes the above flexible circuit board mounting assembly, so it also has the above structure and beneficial effects. For other structures, reference can be made to the prior art and will not be elaborated here.
[0058] The flexible circuit board mounting assembly can be fixed in the lamp housing of the headlight by means of bolt connection, snap connection, etc. If the bolt connection method is used for fixation, corresponding connection holes can be opened on the limit baffle 110, which will not be elaborated here.
[0059] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Specific technical means in some embodiments can be partially or wholly incorporated into another embodiment on the premise that they are not explicitly excluded by another embodiment. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the broadest scope consistent with the principles and novel features disclosed herein.
