[0045] The core of the utility model is to disclose a vehicle lamp to simplify the difficulty of adjusting the imaging clarity and focal length of the lens assembly and the radiator assembly during the assembly process.

[0046] Another core of the utility model is to disclose a vehicle comprising the above-mentioned vehicle lamp.

[0047] The following is an explanation of the embodiments 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 as solutions of the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0048] Combination Figure 1-Figure 12 The vehicle lamp disclosed in the embodiment of the utility model includes a heat dissipation component, a lens component and a first fastener 300. The heat dissipation component includes a heat dissipation substrate 100 and a first mounting seat 110. The first mounting seat 110 is arranged on the first side of the heat dissipation substrate 100, and the first mounting seat 110 is annular, and a first threaded matching portion is arranged on the first mounting seat 110; a second mounting seat 210 is arranged on the lens assembly, the second mounting seat 210 is annular, and a second threaded matching portion screwed with the first threaded matching portion is arranged on the second mounting seat 210; a first fastening screw hole 112 is opened on the first mounting seat 110 or the second mounting seat 210, and the first fastener 300 is threadedly matched with the first fastening screw hole 112 and is used to connect the first mounting seat 110 and the second mounting seat 210.

[0049] When installing the lens assembly on the heat dissipation assembly, first align the first mounting seat 110 and the second mounting seat 210, and then adjust the relative positions of the lens assembly and the heat dissipation assembly by screwing the first threaded fitting portion and the second threaded fitting portion. After adjustment, tighten the first mounting seat 110 and the second mounting seat 210 by screwing the first fastener 300 to complete the position adjustment and fixation of the lens assembly and the heat dissipation assembly.

[0050] Compared with the prior art, the utility model realizes the distance adjustment of the heat dissipation assembly and the lens assembly through the threaded cooperation of the first mounting seat 110 and the second mounting seat 210, which is more convenient to adjust, effectively reduces the difficulty of adjusting the imaging clarity and focal length when assembling the heat dissipation assembly and the lens assembly, and has a simple structure.

[0051] Combination Figure 3 , Figure 6 and Fig. 9 In a specific embodiment disclosed in the present utility model, the second mounting seat 210 is arranged in the first mounting seat 110, and the first threaded matching portion is arranged on the inner wall of the first mounting seat 110, and the second threaded matching portion is arranged on the outer wall of the second mounting seat 210; correspondingly, a first fastening screw hole 112 is opened through the first mounting seat 110, and the first fastener 300 is arranged on the first mounting seat 110 for pressing the outer wall of the second mounting seat 210.

[0052] During assembly, the lens assembly is rotated clockwise or counterclockwise to control the screw-in depth of the lens assembly, thereby adjusting the distance from the lens assembly to the light-emitting core of the light-emitting assembly 400 on the heat dissipation substrate 100 to achieve adjustment of imaging clarity.

[0053] Specifically, combined Figure 8 , Fig.10 and Fig.11 The lens assembly includes a lens holder 200 and an outer lens 230 . A second mounting seat 210 is disposed at the first end of the lens holder 200 . The outer lens 230 is detachably disposed at the second end of the lens holder 200 . The light emitting assembly 400 emits light from the outer lens 230 .

[0054] Combination Figure 4 A positioning boss 220 is provided between the second mounting seat 210 and the lens bracket 200. The positioning boss 220 is used to abut against the end surface of the first mounting seat 110 facing away from the heat dissipation substrate 100 to limit the extreme position of the lens assembly being screwed and moved relative to the heat dissipation assembly.

[0055] Furthermore, in order to enhance the reliability of the fixing of the lens assembly and the heat dissipation assembly, Fig.12 The vehicle lamp further includes a second fastener 310 , and a second fastening screw hole threadably matched with the second fastener 310 is provided on the positioning boss 220 . The second fastener 310 is used to press the end surface of the first mounting seat 110 facing away from the heat dissipation substrate 100 .

[0056] During the assembly process, after the relative positions of the lens assembly and the heat dissipation assembly are adjusted, the first fastener 300 is first screwed to press the second mounting seat 210, and then the second fastener 310 is screwed to press the first mounting seat 110 to complete the assembly.

[0057] There are multiple second fasteners 310 evenly arranged around the circumference of the first mounting seat 110 .

[0058] Combination Figure 5 and Figure 7 The light-emitting component 400 (including components such as a light-emitting lamp panel and an inner lens) is used to be arranged on the first side of the heat dissipation substrate 100, and is arranged in the first mounting seat 110 and the second mounting seat 210; a first avoidance gap 111 is opened on the first mounting seat 110, and a second avoidance gap 211 is opened on the second mounting seat 210. The first avoidance gap 111 and the second avoidance gap 211 are connected to each other for connecting the wiring component 410 of the light-emitting component 400 to the outside world.

[0059] Those skilled in the art can understand that the number of threads of the first thread matching part and the second thread matching part (the number of threads refers to the number of turns of the complete thread) is relatively small, usually two or three threads. Alternatively, the maximum relative rotation angle of the first mounting seat 110 and the second mounting seat 210 is set to be smaller than the central angle angle corresponding to the first avoidance notch 111 and the second avoidance notch 211 (that is, the number of threads of the first thread matching part and the second thread matching part can be one thread), so as to ensure that the positions of the first avoidance notch 111 and the second avoidance notch 211 correspond to each other after the lens assembly and the heat dissipation assembly are assembled.

[0060] According to a further optimization scheme, the spacing distance between the first fastening screw hole 112 and the heat dissipation substrate 100 is smaller than the spacing distance between the first threaded fitting portion and the heat dissipation substrate 100, so that the first fastener 300 can avoid the position of the first threaded fitting portion to avoid damage to the thread of the first threaded fitting portion.

[0061] In addition, the first mounting seat 110 and the second mounting seat 210 can also be interchanged, that is, the first mounting seat 110 is arranged inside the second mounting seat 210, and correspondingly, the first threaded fitting portion is arranged on the outer wall of the first mounting seat 110, and the second threaded fitting portion is arranged on the inner wall of the second mounting seat 210; a first fastening screw hole 112 is opened through the second mounting seat 210, and the first fastener 300 is arranged on the second mounting seat 210 and is used to tighten the outer wall of the first mounting seat 110.

[0062] In a specific embodiment disclosed in the utility model, a plurality of first fastening screw holes 112 are formed through the first mounting seat 110, and the first fastening screw holes 112 are evenly arranged around the circumference of the first mounting seat 110, and the first fastening member 300 is a fastening screw that is screwed and matched with the first fastening screw holes 112 in a one-to-one correspondence. After the lens assembly and the heat dissipation assembly are assembled in place, the first fastening member 300 can be rotated to press the second mounting seat 210 to ensure reliable connection between the heat dissipation assembly and the lens assembly.

[0063] Combination Figure 1 A heat dissipation fin 120 is disposed on the second side of the heat dissipation substrate 100 , and the heat of the light emitting component 400 is dissipated into the air through the heat dissipation fin 120 after being conducted through the heat dissipation substrate 100 .

[0064] In one embodiment, a liquid cooling plate is disposed on the second side of the heat dissipation substrate 100 , and the heat of the light emitting component 400 is conducted through the heat dissipation substrate 100 and then exchanges heat with the liquid cooling plate.

[0065] The vehicle disclosed in the embodiment of the utility model includes the above-mentioned vehicle lamp, so it also has the above-mentioned structure and beneficial effects. Other structures refer to the prior art and will not be described in detail here.

[0066] The above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the utility model. Various modifications to these embodiments will be obvious to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model.
