[0024] A detailed description of the present disclosure is provided below with reference to the accompanying drawings to make other objectives and advantages of the present disclosure obvious and help achieve a comprehensive understanding of the present disclosure.

[0025] Embodiments of the present disclosure will be described in detail below with reference to the drawings. The following description of embodiments of the present disclosure with reference to the drawings is intended to explain the overall disclosed concept of the present disclosure. As those skilled in the art will realize, the embodiments described could be modified in various ways without departing from the concept of the present application, and should not be construed as limiting the present disclosure. Therefore, the drawings and the description are essentially exemplary rather than limiting. Hereinafter, identical reference numerals generally denote functionally identical or similar elements.

[0026] In addition, in the following detailed description, for ease of explanation, many specific details are expounded to provide a comprehensive understanding of embodiments of the present disclosure. However, it is obvious that one or more embodiments may also be implementedwithout these specific details. In other scenarios, well-known structures and devices are shown in the form of illustrations to simplify the drawings.

[0027] When a vehicle lamp is being designed, it is sometimes necessary to achieve a specific shape, and this will restrict the way in which a PCB can be arranged, as well as limiting the space in which it can be arranged. Fig. 1 shows a schematic drawing 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 a first end 1011 and a second end 1012 which are opposite one another; and a second PCB 102 arranged in a second plane intersecting the first plane, an end number one 1021 of the second PCB 102 being arranged close to the first PCB 101, wherein the first plane and the second plane are both perpendicular to a reference plane. The first end 1012 of the first PCB 101 and end number one 1021 of the second PCB 102 are separately fixed to a supporting element 103, and the second end 1012 of the first PCB 101 abuts end number one 1021 of the second PCB 102. The first plane and the second plane are planes in which main planes of the PCBs lie; the reference plane is a plane in which a light exit window lies, i.e. the XY plane. The angle at which the first plane and the second plane intersect may be adjusted as required; the drawings of the present application merely provide an indication thereof, and do not constitute any limitation.

[0028] The first PCB 101 and the second PCB 102 are arranged on the supporting element 103, on which are formed channels (not shown) for respectively accommodating the first PCB 101 and the second PCB 102. The channelscan achieve preliminary positioning of the PCBs; limiting structures, such as fixing posts, for limiting displacement of the PCBs are provided at two sides of the channels. The first end 1012 of the first PCB 101 and end number one 1021 of the second PCB 102 are separately fixed to the supporting element 103, so as to limit displacement of the PCBs in a vertical direction as shown in the figures. It should be understood that the vertical direction referred to here and hereinbelow is the Z-axis direction in the figures, not the actual vertical direction after the PCBs have been fitted. In the example shown in Fig. 1, the supporting element 103 is part of a light reflecting bowl 200, and the first PCB and the second PCB are fixed to the supporting element with screws. In another example, the supporting element 103 may be a separate component; the first PCB and the second PCB may be fixed to the supporting element in any suitable manner.

[0029] In an example, as shown in Figs. 2 and 3, end number one 1021 of the second PCB 102 is press-joined to the top of the second end 1012 of the first PCB 101. The first PCB 101 and the second PCB 102 are both arranged vertically; at the second end 1012 side of the first PCB 101, due to space restrictions, it is not possible to provide an additional fixing means to fix same. In the present application, to ensure fixing at the second end 1012 side of the first PCB 101, end number one of the second PCB 102 is pressed against the top of the first PCB 101, so as to fix and limit same in the vertical direction.

[0030] Specifically, to assemble, the first PCB is first positioned in the channel formed on the supporting element, then the first end thereof is fixed tothe supporting element with a screw, then the second PCB is positioned, and end number one thereof is pressed tightly against the top of the second end of the first PCB, then the second PCB is fixed to the supporting element with a screw. With such an arrangement, the second end of the first PCB 101 can be fixed without any need for an additional fixing element, so assembly can be simplified and space can be saved.

[0031] In an example, as shown in Figs. 1 - 4, end number one 1021 of the second PCB 102 has a recessed structure 1022 which is recessed inwards with respect to a lower side face of the second PCB 102; a plane of the recessed structure 1022 is press-joined to the top of the second end 1012 of the first PCB 101. The meaning of "recessed structure 1022" is that a width of the second PCB 102 at the recessed structure is reduced with respect to a main body portion thereof. The plane of the recessed structure 1022 may form any suitable angle with a side edge of the second PCB 102; it may be parallel to an upper side edge of the second PCB 102 as shown in Fig. 4, or parallel to a lower side edge, or may be at another suitable angle. The present application imposes no specific restrictions.

[0032] In the present application, due to width requirements of the second PCB 102, the design of the recessed structure 1022 can ensure that electronic components on the second PCB 102 have sufficient space to be arranged without introducing any additional space requirements in the Z-axis direction, and at the same time enables the second end 1012 of the first PCB 101 to be fixed. The recessed structure 1022 may be obtained by extending a length of the second PCB 102, or by cutting out a portion ofend number one 1021 of the second PCB 102. The present application imposes no specific restrictions.

[0033] Figs. 5 - 12 shows other embodiments of a PCB fixing mechanism according to the present application. In the interests of conciseness, only differences with respect to the first embodiment are pointed out and described in the following description. Besides having the advantages of the first embodiment, the following embodiments also have other advantages due to the differences therein. Although the recessed structure 1022 is shown in Figs. 5 - 12, it should be known that the recessed structure 1022 is not a required structure in these embodiments, and the lack of the recessed structure would not affect the achievement of the objective and effect of these embodiments.

[0034] In an example, as shown in Figs. 5 and 6, a first engaging slot 1013 is formed on the second end 1012 of the first PCB 101, and end number one 1021 of the second PCB 102 is inserted in the first engaging slot 1013. Such an arrangement can restrict displacement of the first PCB 101 in the Z-axis direction, and can further restrict displacement of the first PCB 101 and the second PCB 102 in the X-axis direction, to obtain a better positioning and fixing effect. To facilitate assembly, a chamfer is provided at an opening of the first engaging slot 1013. The dimensions of the first engaging slot 1013, and the specific position thereof at the second end 1012 of the first PCB 101, can be adjusted as required; the present application imposes no specific restrictions.

[0035] In an example, as shown in Figs. 7 and 8, a second engaging slot 1023 is formed on end number one 1021 of the second PCB 102, and the second end 1012 of the first PCB 101 is inserted in the second engaging slot 1023. Such an arrangement can restrict displacement of the first PCB 101 in the Z-axis direction, and can further restrict displacement of the first PCB 101 and the second PCB 102 in the Y-axis direction, to obtain a better positioning and fixing effect. To facilitate assembly, a chamfer is provided at an opening of the second engaging slot 1023. The dimensions of the second engaging slot 1023, and the specific position thereof at end number one 1021 of the second PCB 102, can be adjusted as required; the present application imposes no specific restrictions.

[0036] In an example, as shown in Figs. 8 and 10, a second engaging slot 1023 is formed on end number one 1021 of the second PCB 102, and the first engaging slot 1013 is engaged in the second engaging slot 1023. Such an arrangement can restrict displacement of the first PCB 101 in the Z-axis direction, and can further restrict displacement of the first PCB 101 and the second PCB 102 in the X-axis and Y-axis directions, to obtain a better positioning and fixing effect. To facilitate assembly, a chamfer is provided at an opening of at least one of the first engaging slot 1013 and the second engaging slot 1023. The dimensions of the first engaging slot 1013 and the second engaging slot 1023, and the specific positions thereof on the respectively corresponding PCBs, can be adjusted as required; the present application imposes no specific restrictions.

[0037] In an example, as shown in Figs. 11 and 12, a hole 1014 is provided in the second end 1012 of the first PCB 101, a protrusion 1024 is formed on endnumber one 1021 of the second PCB 102, and the protrusion 1024 passes through the hole 1014. The protrusion 1024 on the second PCB 102 is arranged in a width direction of the second PCB 102, and projects towards the first PCB 101. Correspondingly, the hole 1014 is provided in the first PCB. By passing the protrusion 1024 through the hole 1014, the first PCB 101 and the second PCB 102 can be fixed in the X-axis and Z-axis directions.

[0038] Specifically, the protrusion 1024 comprises a hook-shaped structure 1025, configured to prevent the protrusion 1024 from coming out of the hole 104. Due to the hook-shaped structure 1025, displacement of the first PCB 101 and the second PCB 102 in the Y-axis direction is restricted, further enhancing the effect and reliability of fixing. The hook-shaped structure 1025 shown in Figs. 11 and 12 extends upwards in the Z-axis direction, but it should be known that it could also extend downwards. The specific configuration can be adjusted as required. The protrusion 1024 is preferably formed integrally with the second PCB 102.

[0039] In the drawings, some of the electronic components are shown at a lower edge of the first PCB 101, but it should be known that this does not limit the present application. The positions and manner of arrangement of electronic components on the first PCB 101 and the second PCB 102 may be designed at will as required.

[0040] In the lamp PCB fixing structure according to the present application, one end of the first PCB is fixed by means of the second PCB, with no need for an additional fixing means; this can reduce the number of steps in anassembly process and reduce the amount of space needed to fit the PCBs, resulting in a more compact vehicle lamp structure.

[0041] The lamp PCB fixing structure of the present application may be used in vehicle lamps with different light emission functions in a vehicle, such as vehicle lamps performing a lighting function, and may also be used in vehicle lamps performing signalling functions, such as tail lamps, direction indicators, daytime running lamps or position lamps, etc. The present application imposes no specific restrictions in this respect.

[0042] The present application also provides a vehicle, having the PCB fixing structure described above. The vehicle has the advantages of the PCB fixing structure described above. The term "vehicle" mentioned herein may refer to any type of vehicle, e.g. a vehicle, a motorcycle, or any other moving machine capable of carrying at least one passenger or used for transporting people or goods.

[0043] It will be understood that herein the term "one-piece" or "integrated" is relative to the term "independent" or "separate", that is, a one-piece or integrated component exists as a unit, and does not comprise parts independent or separate from each other in space; for example, the various parts of a one-piece or integrated component may be simultaneously formed (for example moulded), or may be separately formed and thereafter assembled together to form a one-piece assembly.

[0044] Although the present disclosure has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of the presentdisclosure demonstratively, and must not be construed as limiting the present disclosure. The dimensional proportions in the drawings are merely schematic, and must not be construed as limiting the present disclosure.

[0045] Although some embodiments of the general concept of the present disclosure have been shown and described, those ordinarily skilled in the art will understand that changes can be made to these embodiments without departing from the principle and spirit of the general concept of the present disclosure. The scope of the present disclosure is defined by the claims and their equivalents.
