[0025] Other objects and advantages of the present disclosure will be readily apparent to those skilled in the art from the detailed description of the present disclosure that follows, taken in conjunction with the accompanying drawings.

[0026] Embodiments of the present disclosure will be described in detail below with reference to the drawings. The following description of the embodiments of the present disclosure with reference to the drawings is intended to explain the general inventive concept of the present disclosure, as those skilled in the art should realize that the described embodiments can be modified in various different ways, without departing from the spirit of the present application, and should not be construed as limiting the present disclosure in any way. Therefore, the drawings and the description are intended to be exemplary in nature and not limiting. In the following, the same reference numerals generally designate the same or similar elements.

[0027] In addition, in the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. It will be apparent, however, to one of ordinary skill in the art that one or more embodiments can be practiced without these specific details. In other instances, well-known structures and devices are not described in detail in order to simplify the drawings.

[0028] In the design of vehicle lamps, sometimes it is necessary to achieve a specific shape, thereby limiting the arrangement and space of the PCB. For example, Figure 1Fig. 1 shows a schematic view of a lamp PCB fixing structure according to the present application. Specifically, the lamp PCB fixing structure comprises a first PCB 101 arranged in a first plane and having opposite first and second ends 1011, 1012, and a second PCB 102 arranged in a second plane intersecting the first plane, and an end portion 1021 of the second PCB 102 is arranged adjacent to the first PCB 101, wherein the first and second planes are both perpendicular to a reference plane. The first end 1012 of the first PCB 101 and the end portion 1021 of the second PCB 102 are fixed to a support element 103 respectively, and the second end 1012 of the first PCB 101 abuts against the end portion 1021 of the second PCB 102. The first and second planes refer to the planes in which the main planes of the PCBs lie, and the reference plane refers to the plane in which the light window lies, i.e. the XY plane. The angle at which the first and second planes intersect can be adjusted as required, and the accompanying drawings of the present application are merely schematic and do not constitute any limitation.

[0029] The first and second PCBs 101, 102 are arranged on the support element 103, which has channels (not shown) for accommodating the first and second PCBs 101, 102 respectively. The channels can achieve preliminary positioning of the PCBs, and the two sides of the channels are provided with limiting structures such as fixing columns to limit displacement of the PCBs. The first end 1012 of the first PCB 101 and the end portion 1021 of the second PCB 102 are fixed to the support element 103 respectively, thereby limiting displacement of the PCBs in the upward and downward directions as shown in the figure. It should be understood that the upward and downward directions here and in the following refer to the Z-axis direction in the accompanying drawings, rather than the actual upward and downward directions of the PCBs after assembly. In the example shown, the support element 103 is part of a reflector bowl 200, and the fixing between the first and second PCBs and the support element is achieved by screws. In another example, the support element 103 can be a separate component, and the fixing between the first and second PCBs and the support element can be achieved in any suitable manner. Figure 1 In the example shown, the support element 103 is part of a reflector bowl 200, and the fixing between the first and second PCBs and the support element is achieved by screws. In another example, the support element 103 can be a separate component; the fixing between the first and second PCBs and the support element can be achieved in any suitable manner.

[0030] In one example, as shown in Fig. 2, the first and second PCBs 101, 102 are arranged in a first plane and a second plane respectively, and the first and second planes are both perpendicular to a reference plane. The first and second PCBs 101, 102 are fixed to a support element 103 respectively, and the first and second PCBs 101, 102 abut against each other. The first and second planes refer to the planes in which the main planes of the PCBs lie, and the reference plane refers to the plane in which the light window lies, i.e. the XY plane. The angle at which the first and second planes intersect can be adjusted as required, and the accompanying drawings of the present application are merely schematic and do not constitute any limitation. Figure 2 and Figure 3As shown, the end one 1021 of the second PCB board 102 is pressed on the second end 1012 of the first PCB board 101. The first PCB board 101 and the second PCB board 102 are both vertically arranged. On the side of the second end 1012 of the first PCB board 101, due to the limitation of space, no additional fixing device can be arranged to fix it. In the present application, in order to ensure the fixation of the side of the second end 1012 of the first PCB board 101, the end one of the second PCB board 102 is pressed on the first PCB board 101, so as to fix and limit the first PCB board 101 in the up-down direction.

[0031] Specifically, in the assembly, the first PCB board is first placed in the channel formed by the support element, and then the first end thereof is fixed to the support element by the screw, and then the second PCB board is placed and the end one thereof is pressed on the second end of the first PCB board, and then the second PCB board is fixed to the support element by the screw. Such arrangement can realize the fixation of the second end of the first PCB board 101 without using additional fixing elements, so as to simplify the assembly and save space.

[0032] In one example, as shown in Figures 1-4 The end one 1021 of the second PCB board 102 has a recessed structure 1022 which is inwardly recessed relative to the lower side of the second PCB board 102, and the plane of the recessed structure 1022 is pressed on the second end 1012 of the first PCB board 101. The recessed structure 1022 refers to the part where the width of the second PCB board 102 is reduced relative to the main body part. The plane of the recessed structure 1022 can be at any suitable angle relative to the side of the second PCB board 102, which can be parallel to the upper side of the second PCB board 102 as shown in Figure 4 , can be parallel to the lower side, or can be at other suitable angles, which are not specifically limited in the present application.

[0033] In the present application, due to the width requirement of the second PCB board 102, the design of the recessed structure 1022 can ensure that the electronic components on the second PCB board 102 have sufficient arrangement space without increasing the additional space requirement in the Z-axis direction, and at the same time, the fixation of the second end 1012 of the first PCB board 101 is realized. The recessed structure 1022 can be obtained by extending the length of the second PCB board 102, or by cutting off a part of the end one 1021 of the second PCB board 102, which is not specifically limited in the present application.

[0034] Figures 5-12Other implementations of the PCB fixing mechanism according to this application are shown. For brevity, only the differences between these implementations and the first implementation will be described in the following description. In addition to the advantages of the first implementation, the following implementations also have other advantages arising from their differences. Although in Figures 5-12 The recessed structure 1022 is shown, but it should be understood that the recessed structure 1022 is not a necessary structure in these implementations, and the absence of the recessed structure does not affect the purpose and effect of these implementations.

[0035] In one example, such as Figure 5 and 6 As shown, a first slot 1013 is formed on the second end 1012 of the first PCB board 101, and the end 1021 of the second PCB board 102 is inserted into the first slot 1013. This arrangement not only restricts the displacement of the first PCB board 101 in the Z-axis direction, but also further restricts the displacement of the first PCB board 101 and the second PCB board 102 in the X-axis direction, achieving better positioning and fixing effects. For ease of assembly, the opening of the first slot 1013 is chamfered. The size of the first slot 1013 and its specific position at the second end 1012 of the first PCB board 101 can be adjusted as needed; this application does not impose specific limitations.

[0036] In one example, such as Figure 7 and 8 As shown, a second slot 1023 is formed on the end 1021 of the second PCB board 102, and the second end 1012 of the first PCB board 101 is inserted into the second slot 1023. This arrangement not only restricts the displacement of the first PCB board 101 in the Z-axis direction, but also further restricts the displacement of the first PCB board 101 and the second PCB board 102 in the Y-axis direction, achieving better positioning and fixing effects. For ease of assembly, the opening of the second slot 1023 is chamfered. The size of the second slot 1023 and its specific position at the end 1021 of the second PCB board 102 can be adjusted as needed; this application does not impose specific limitations.

[0037] In one example, such as Figure 8 and 10As shown, a second slot 1023 is formed on the end 1021 of the second PCB board 102, and the first slot 1013 is engaged in the second slot 1023. This arrangement not only restricts the displacement of the first PCB board 101 in the Z-axis direction, but also further restricts the displacement of the first PCB board 101 and the second PCB board 102 in the X and Y-axis directions, achieving better positioning and fixing effects. For ease of assembly, at least one of the first slot 1013 and the second slot 1023 has a chamfer at its opening. The dimensions of the first slot 1013 and the second slot 1023 and their specific positions on their respective PCB boards can be adjusted as needed; this application does not impose specific limitations.

[0038] In one example, such as Figure 11 and 12 As shown, a hole 1014 is formed on the second end 1012 of the first PCB board 101, and a protrusion 1024 is formed on the end 1021 of the second PCB board 102, the protrusion 1024 passing through the hole 1014. The protrusion 1024 on the second PCB board 102 is positioned along the width of the second PCB board 102 and extends towards the first PCB board 101. Correspondingly, the hole 1014 is formed on the first PCB board. The protrusion 1024 passing through the hole 1014 allows for the fixation of the first PCB board 101 and the second PCB board 102 in the X and Z axis directions.

[0039] Specifically, the tab 1024 includes a hook-like structure 1025 configured to prevent the tab 1024 from dislodging from the hole 104. Due to the hook-like structure 1025, the displacement of the first PCB board 101 and the second PCB board 102 in the Y-axis direction is restricted, further enhancing the fixing effect and reliability. Figure 11 and 12 The hook-shaped structure 1025 shown extends upward in the Y-axis direction, but it should be understood that it can also extend downward, and the specific extension can be adjusted as needed. The tab 1024 is preferably integrated with the second PCB board 102.

[0040] In the accompanying drawings, only some electronic components are shown at the lower edge of the first PCB board 101; however, it should be understood that this does not constitute a limitation on this application. The positions and arrangements of the electronic components on the first PCB board 101 and the second PCB board 102 can be arbitrarily configured as needed.

[0041] According to the lamp PCB board fixing structure of this application, one end of the first PCB board is fixed by the second PCB board, without the need for additional fixing devices. This reduces the number of assembly steps and saves the space required for PCB board assembly, resulting in a more compact vehicle lamp structure.

[0042] The PCB board mounting structure of this application can be used for vehicle lights with different light-emitting functions, such as lights that perform illumination functions, or lights that perform signaling functions, such as taillights, turn indicators, daytime running lights, or position lights. This application does not impose any specific limitations on this.

[0043] This application also provides a vehicle having the aforementioned PCB board fixing structure. The vehicle has the advantages of the aforementioned PCB board fixing structure. The term "vehicle" as used herein can refer to any type of vehicle, such as a car, motorcycle, or any other mobile machine capable of carrying at least one passenger or used for transporting people or goods.

[0044] It will be understood that in this document, the terms “integrated” and “integrated” are relative to “independent” or “separate”, meaning that an integrated or integral part exists as a single unit and does not include parts that are spatially independent or separate from each other. For example, the individual parts of an integrated or integral part may be formed simultaneously (e.g., molded) or they may be formed separately and then assembled together to form a single unit.

[0045] Although this disclosure has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of this disclosure and should not be construed as limiting the disclosure. The dimensions in the drawings are merely illustrative and should not be construed as limiting the disclosure.

[0046] While some embodiments of the general concept of this disclosure have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the general concept of this disclosure, the scope of which is defined by the claims and their equivalents.
