[0002] Existing automotive lighting fixtures, such as Figure 11 As shown, for example, a forward-illuminating lamp 700 includes an electronic board 710. Light sources 711 and control units 712 are spaced apart along the vertical direction on the front sidewall of the electronic board 710. Because the multiple lamps of the light sources 711 must be arranged sequentially along the left-right direction, the control unit 712 must be located above or below the light sources 711. Furthermore, due to the relatively narrow length of the electronic board 710 in the left-right direction, the electronic board 710 needs to be designed to be taller in the vertical direction to accommodate the control unit 712 with its numerous electronic components. Therefore, the lamp is relatively thick in the vertical direction, making it inconvenient to install in the front grille of a car or other thinner spaces within the vehicle. Utility Model Content

[0038] Reference Figure 1 , 2 As shown, the automotive lighting fixture according to an embodiment of the present invention includes a housing assembly 100, a lamp plate 200, and a control board 300. The housing assembly 100 has a mounting cavity 110 extending laterally; the lamp plate 200 is mounted within the mounting cavity 110 and extends laterally, as shown below. Figure 2 , 3 As shown, the front side of the lamp panel 200 has a light source 210, and the light from the light source 210 can pass through the housing assembly 100 and shine forward; as Figure 2 , 4 As shown, the control board 300 is installed in the mounting cavity 110 and located behind the lamp board 200. The control board 300 extends in the left and right direction and is provided with electronic components 310 for controlling the light source 210. The control board 300 is electrically connected to the lamp board 200.

[0039] This invention divides the electronic board into a lamp board 200 and a control board 300, both of which, along with the housing assembly 100, extend in the left-right direction. This design allows the housing assembly 100 to accommodate the elongated lamp board 200 and control board 300. Multiple light sources 210 can be arranged on the lamp board 200 in the left-right direction, thereby providing sufficient illumination while maintaining a minimum vertical height. Similarly, multiple electronic components 310 can also be arranged on the control board 300 in the left-right direction, achieving a minimum vertical height. These designs collectively enable the entire automotive lighting fixture to be very thin. Due to the aforementioned structure, the automotive lighting fixture can be mounted on the front grille of a car, or installed under the car as a reversing light, or installed in areas of the car with low vertical height.

[0040] Specifically, such as Figure 1 , 2 As shown, the housing assembly 100 includes a body 102, a lens 103 and a mask 104. The mask 104 is mounted on the left side of the body 102. The mask 104 and the body 102 together enclose a mounting cavity 110. The lens 103 is mounted in the mounting cavity 110 and is located in front of the light source 210.

[0041] During operation, the control board 300 turns on the light source 210 of the lamp board 200 through the electronic component 310. The light from the light source 210 shines forward onto the lens 103, and the lens 103 makes the light pass through the mask 104 and shine forward.

[0042] Specifically, a portion of the mask 104 can be inserted into the body 102 and the two are fixed together by glue, and the mask 104 can press the lens 103 onto the lamp panel 200.

[0043] Specifically, such as Figure 2 As shown, the lamp panel 200 is placed vertically, and thus the left side wall of the lamp panel 200 has sufficient installation area, so that the light source 210 can be installed on the left side wall of the lamp panel 200.

[0044] In some embodiments of this utility model, such as Figure 1 , 4 As shown, the control board 300 has a first surface 301, a second surface 302, and a side surface 303 connecting the first surface 301 and the second surface 302. The first surface 301 and the second surface 302 are arranged opposite to each other. The area of ​​the first surface 301 and the area of ​​the second surface 302 are both larger than the area of ​​the side surface 303. The electronic component 310 is located on the first surface 301 and / or the second surface 302. The first surface 301 and the second surface 302 are both parallel or perpendicular to the horizontal plane.

[0045] The above structure allows the control board 300 to be placed either vertically or horizontally, enabling it to be adjusted according to actual installation needs.

[0046] Understandably, since multiple electronic components 310 make full use of the space in the left and right directions of the control board 300, the height of the control board 300 in the vertical direction will not be too high, regardless of whether the control board 300 is placed horizontally or vertically, thus not affecting the slim design of the automotive lighting fixture.

[0047] Preferably, such as Figure 1 , 2 As shown, the control board 300 is placed horizontally, that is, the first surface 301 and the second surface 302 are both parallel to the horizontal plane. With this design, the height between the first surface 301 and the second surface 302 can be made thinner, with only the electronic components 310 being relatively tall, making full use of the space within the mounting cavity 110 to design other structures.

[0048] In some embodiments of this utility model, such as Figure 2 As shown, the mounting cavity 110 has a partition 111, which is used to divide the mounting cavity 110 into a front chamber 112 and a rear chamber 113. The lamp panel 200 is located in the front chamber 112, and the control panel 300 is located in the rear chamber 113.

[0049] The partition 111 provides a heat insulation effect.

[0050] In a further embodiment of the present invention, the control board 300 is installed in the rear chamber 113 in a suspended manner to facilitate heat dissipation of the electronic components 310 on the control board 300.

[0051] In a further embodiment of this utility model, such as Figure 2 As shown, the partition 111 has a connecting hole 114, the rear chamber 113 is connected to the front chamber 112 through the connecting hole 114, and the control board 300 is electrically connected with wires (not shown in the figure). The wires can pass through the connecting hole 114 and be electrically connected to the lamp board 200.

[0052] When the mounting cavity 110 is provided with a partition 111, the control board 300 and the lamp board 200 are conveniently connected by a connecting hole 114.

[0053] Specifically, the wires can be quickly connected to the control board 300 or the lamp board 200 through the terminal blocks, improving the installation efficiency of automotive lighting fixtures.

[0054] In a further embodiment of this utility model, such as Figure 5 As shown, the control panel 300 is placed horizontally; as Figure 5 As shown, the rear chamber 113 has multiple support portions 1131 spaced apart in the left-right direction and multiple positioning portions 1132 spaced apart in the left-right direction, such as... Figure 4 As shown, the control board 300 has a snap-fit ​​hole 304 that engages with the positioning part 1132, such as Figure 6 As shown, the control board 300 is placed on the support part 1131, the positioning part 1132 is located in the snap-fit ​​hole 304, and at least one support part 1131(a) has a screw hole 11311, and a first screw 1133 is installed in the screw hole 11311. The first screw 1133 is used to fix the control board 300 on the support part 1131.

[0055] The control board 300 is supported by a support part 1131, allowing it to be suspended in the air, which makes it easier to dissipate heat from the electronic components 310 of the control board 300. The control board 300 is fixed to the support part 1131 by the first screw 1133, which facilitates the installation and removal of the control board 300 and its vertical positioning. The positioning part 1132 can limit the position of the control board 300 in the left-right and front-back directions, preventing the control board 300 from moving left-right or front-back within the mounting cavity 110, thereby avoiding abnormal noise from the automotive lighting fixtures.

[0056] During installation, the control board 300 is placed on the support part 1131, and the positioning part 1132 is located in the snap-fit ​​hole 304. The first screw 1133 passes through the control board 300 and is connected to at least one support part 1131, thereby fixing the control board 300 to the support part 1131.

[0057] During disassembly, simply loosen the first screw 1133 and remove the control board 300.

[0058] Specifically, such as Figure 5 As shown, two positioning parts 1132 and two snap-fit ​​holes 304 are provided, and multiple support parts 1131 are located between the two positioning parts 1132.

[0059] In a further embodiment of this utility model, such as Figure 5 , 7 As shown in Figures 8 and 9, at least one support portion 1131(b) has a vent 1134 extending in the front-rear direction. The front end of the vent 1134 communicates with the front chamber 112, and the rear end of the vent 1134 communicates with the outside of the housing assembly 100.

[0060] By providing a vent hole 1134 in the support portion 1131(b) where the first screw 1133 is not installed, the structure of the support portion 1131 is fully utilized, so that the support portion 1131 can both support the control board 300 and dissipate heat for the lamp board 200.

[0061] Specifically, the support part 1131(b) may or may not have a screw hole 11311.

[0062] In a further embodiment of this utility model,

[0063] like Figure 6 As shown, when the control plate 300 is placed on the support part 1131, the height of the upper end surface of the control plate 300 is lower than the height of the upper end surface of the positioning part 1132.

[0064] The upper side of the rear chamber 113 has an opening 1135 that communicates with the outside of the housing assembly 100, through which the top of the support 1131 can be placed on the control panel 300.

[0065] like Figure 8 , 9 As shown in Figure 10, the automotive lighting fixture also includes a cover plate 400 and a second screw 500. The cover plate 400 is placed on top of the positioning part 1132 and located in the opening 1135. The second screw 500 passes through the cover plate 400 and is connected to the positioning part 1132.

[0066] Since the upper surface of the control board 300 is lower than the upper surface of the positioning part 1132 when the control board 300 is placed on the support part 1131, there is a gap between the lower surface of the cover plate 400 and the upper surface of the control board 300 when the cover plate 400 is placed on the positioning part 1132, which facilitates heat dissipation of the control board 300.

[0067] By providing a cover plate 400 and a second screw 500, the control board 300 can be installed or removed simply by turning the second screw 500 and removing or placing the cover plate 400.

[0068] In a further embodiment of this utility model, such as Figure 5 , 8 As shown in Figure 10, at least one support portion 1131(c) has a mounting hole 1136 that extends rearward in a front-rear direction and communicates with the outside of the housing assembly 100. A third screw 1137 is mounted in the mounting hole 1136 and is connected to a mounting bracket 600 that can be mounted on an automobile.

[0069] By providing mounting holes 1136 in the support portion 1131(c) where the first screw 1133 is not installed, the structure of the support portion 1131 is fully utilized, so that the support portion 1131 can both support the control board 300 and provide a position for the installation of the third screw 1137.

[0070] Mounting bracket 600 can be installed on the front grille of a car, the bottom of the car, or other locations on the car.

[0071] Specifically, the support portion 1131(c) may or may not have a screw hole 11311.

[0072] In a further embodiment of this utility model, such as Figure 1 As shown, the rear sidewall 101 of the housing assembly 100 is arc-shaped, and the part of the mounting bracket 600 that matches the rear sidewall 101 is arc-shaped. When the third screw 1137 is loosened from the mounting bracket 600, the mounting bracket 600 can move along the arc of the rear sidewall 101.

[0073] The rear sidewall 101 of the housing assembly 100 and the portion of the mounting bracket 600 that matches the rear sidewall 101 are both arc-shaped, allowing the mounting bracket 600 to be angle-adjustable, thus improving the applicability of automotive lighting fixtures.

[0074] Specifically, the mounting bracket 600 has an adjustment hole (not shown in the figure) on the rear side wall 101 of the housing assembly 100, and the third screw 1137 is located in the adjustment hole. When the angle needs to be adjusted, the third screw 1137 is loosened, and the mounting bracket 600 is driven to move along the arc-shaped rear side wall 101 of the housing assembly 100, so that the position of the third screw 1137 in the adjustment hole changes. After the angle is adjusted, the third screw 1137 is tightened, thereby fixing the mounting bracket 600 to the housing assembly 100.
