Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a lighting controller and a lighting lamp. Background Technology

[0002] Vehicle lights are tools for illuminating roads when vehicles are driving at night, and also tools for issuing various vehicle driving signals.

[0003] The vehicle lighting controller is an electronic control unit responsible for receiving driver commands and sensor signals. Through internal logic processing, it precisely controls the switching, brightness adjustment, and mode conversion of all internal and external lights of the vehicle, thereby achieving safe lighting and intelligent lighting management.

[0004] However, with the increasing functionality of automotive lights, the power consumption of the light controller has risen significantly, making heat dissipation a growing concern. The light controller consists of an upper and lower housing. Along the thickness of the lower housing, there are upper and lower surfaces, with the upper housing fixedly connected to the upper surface. Existing technologies often employ multiple independent heat dissipation fins on the lower surface of the lower housing, extending along its thickness to increase the heat dissipation area and improve cooling efficiency. While this method increases the heat dissipation area, the upper housing and heat dissipation fins are located on opposite sides of the lower housing, increasing the space occupied by the light controller and hindering compact light design. Another approach is to use a coating process on the lower surface of the lower housing, utilizing the thermal radiation properties of the coating material to aid heat dissipation. However, this process is costly, imposing an additional economic burden.

[0005] Therefore, there is an urgent need for a vehicle lighting controller and vehicle lighting that has low heat dissipation costs and a compact structure. Utility Model Content

[0006] The purpose of this invention is to solve the problems of high heat dissipation cost and large space occupation of existing vehicle light controllers.

[0007] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a vehicle light controller, comprising:

[0008] Upper housing, with a base;

[0009] The lower housing includes a bottom plate, the bottom plate including a first side wall and a second side wall, the first side wall having an upwardly bent first heat dissipation rib, and the second side wall having an upwardly bent second heat dissipation rib; the bottom plate, the first heat dissipation rib, and the second heat dissipation rib together form an accommodating area;

[0010] The base plate is fixedly connected to the base, the base is located in the receiving area, and the first heat dissipation rib, the second heat dissipation rib and the base are spaced apart.

[0011] By employing the above technical solution, the effective heat dissipation area of ​​the lower housing is increased by setting the first and second heat dissipation ribs that bend upwards on the base plate, thereby improving the overall heat dissipation performance of the vehicle lighting controller. The first and second heat dissipation ribs and the base plate form a receiving area, and the upper housing is located within this area. That is, the first and second heat dissipation ribs and the upper housing are located on the same side of the base plate, and the first and second heat dissipation ribs do not occupy space on the other side of the base plate, thus making the layout of the vehicle lighting controller compact. The first and second heat dissipation ribs are spaced apart from the upper housing to avoid heat accumulation and ensure uniform heat dissipation of the vehicle lighting controller.

[0012] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a vehicle light controller, wherein the extension direction of the first heat dissipation rib forms an angle α with the base plate, 90°≤a<180°; and the extension direction of the second heat dissipation rib forms an angle b with the base plate, 90°≤b<180°.

[0013] By adopting the above technical solution, the included angles between the first and second heat dissipation ribs and the base plate are both set between 90° and 180°. This means that, given the same size for the first and second heat dissipation ribs, the opening of the resulting receiving area is larger, facilitating the installation and positioning of the upper shell and the base plate. Conversely, if the included angle is less than 90°, i.e., the first and second heat dissipation ribs form an acute angle with the base plate, the opening of the resulting receiving area is smaller, requiring a larger base plate to allow the upper shell to pass through the opening, resulting in a larger space occupied by the base plate.

[0014] In addition, during vehicle operation, the air in front flows over the headlight area. The design of the first and second heat dissipation fins, which are inclined relative to the base plate, can adapt to the changes in airflow direction caused by different headlight shapes. By designing the angle, the first and second heat dissipation fins can increase the frontal area, thereby increasing the convective heat transfer efficiency and improving the heat dissipation efficiency.

[0015] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a vehicle light controller, wherein the included angle a is 90° and the included angle b is 90°.

[0016] By adopting the above technical solution, the first and second heat dissipation ribs are set perpendicular to the base plate, meaning that the first and second heat dissipation ribs only extend along the height direction (second direction) and do not extend horizontally. This reduces the space occupied in the horizontal direction, optimizes the spatial layout of the headlight controller, and thus reduces the overall space occupied by the headlight controller within the headlight.

[0017] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a vehicle light controller, wherein the base has a first outer wall and a second outer wall, the first outer wall is provided with a mounting protrusion, and the mounting protrusion extends along a first direction;

[0018] The first outer wall is provided with a first groove, which is located on one side of the mounting protrusion. The first groove corresponds to the first heat dissipation rib, and the first heat dissipation rib is disposed in the first groove. The second outer wall is provided with a second groove, which corresponds to the second heat dissipation rib, and the second heat dissipation rib is disposed in the second groove.

[0019] Using the above technical solution, a mounting protrusion is provided on the first outer wall of the base for connecting the headlight controller to other components of the headlight. A first groove is provided on one or both sides of the mounting protrusion, meaning the position of the first groove avoids the mounting protrusion. A second groove is provided on the second outer wall. The first and second grooves correspond one-to-one with the first and second heat dissipation ribs, which are located within the grooves to position them and prevent misalignment during installation.

[0020] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a vehicle light controller, wherein the length of the first heat dissipation fin is less than the length of the second heat dissipation fin.

[0021] By adopting the above technical solution, the second heat dissipation rib is longer than the first heat dissipation rib, thus increasing the heat dissipation area. The first heat dissipation rib is shorter, effectively avoiding space constraints for mounting protruding structures.

[0022] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a vehicle light controller, wherein the thickness of the first heat dissipation fin and the second heat dissipation fin is greater than or equal to 1 mm.

[0023] By adopting the above technical solution, by setting the thickness of the first heat dissipation fin and the second heat dissipation fin to not less than 1mm, problems such as insufficient heat conduction cross section and small heat capacity caused by the first heat dissipation fin and the second heat dissipation fin being too thin can be effectively avoided, thereby improving the heat dissipation efficiency of the first heat dissipation fin and the second heat dissipation fin.

[0024] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a vehicle light controller, wherein the upper housing includes:

[0025] A connector is provided on the base and has an upper end face along the second direction;

[0026] The first heat dissipation fin has a first top surface, and the second heat dissipation fin has a second top surface;

[0027] Along the second direction, neither the first top surface nor the second top surface is higher than the upper end surface.

[0028] By adopting the above technical solution, the overall height and shape of the headlight controller are effectively reduced by limiting the top height of the first and second heat dissipation fins to below the upper surface of the connector. This avoids spatial interference with surrounding components in the second direction (i.e., the height direction), making it particularly suitable for headlight interiors where installation space is limited, resulting in a more compact layout for the headlight controller.

[0029] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a vehicle light controller, wherein the base plate, the first heat dissipation rib, and the second heat dissipation rib are integrally formed; wherein the first heat dissipation rib and the second heat dissipation rib are formed by a bending process.

[0030] By employing the above technical solution, the base plate, the first heat dissipation fin, and the second heat dissipation fin are manufactured using an integrated molding process. Furthermore, the bending angles of the first and second heat dissipation fins are set through a bending process to adapt to different heat dissipation requirements. Compared to a coating process, bending the first and second heat dissipation fins at angles can also improve the convective heat dissipation capability of the vehicle lighting controller. This molding method eliminates assembly gaps and contact thermal resistance between parts, not only improving the overall mechanical strength and vibration reliability of the lower housing but also eliminating contact thermal resistance caused by the assembly interfaces of the parts, thereby avoiding the resulting loss of heat dissipation efficiency.

[0031] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a vehicle light controller, wherein the lower housing is made of aluminum alloy.

[0032] By employing the above technical solution and using aluminum alloy to manufacture the lower housing, the excellent thermal conductivity of aluminum alloy is fully utilized, allowing for rapid heat transfer from the interior of the headlight controller to the surfaces of the base plate, the first heat dissipation fin, and the second heat dissipation fin. Simultaneously, aluminum alloy possesses characteristics such as low density, high strength, and corrosion resistance, significantly reducing the overall weight while ensuring efficient heat dissipation.

[0033] This utility model also discloses a vehicle light, comprising:

[0034] As in any of the above embodiments, the vehicle light controller;

[0035] The headlight housing, wherein the upper housing of the headlight controller is connected to the headlight housing. Attached Figure Description

[0059] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0060] refer to Figure 1 , Figure 2This application provides a vehicle lighting controller 100, including: an upper housing 110 and a lower housing 120. The lower housing 120 includes a base plate 121, which includes a first side wall 1211, a second side wall 1212, a third side wall 1213, and a fourth side wall 1214. The first side wall 1211 is provided with two upwardly bent first heat dissipation ribs 122, and the second side wall 1212 and the fourth side wall 1214 are each provided with one upwardly bent second heat dissipation rib 123.

[0061] In some possible implementations, the third sidewall 1213 may also be provided with an upwardly bent first heat dissipation rib 122 or a second heat dissipation rib 123, depending on the internal layout of the headlight 200. This application does not limit this implementation.

[0062] In some possible implementations, the number of first heat dissipation fins 122 may include, but is not limited to, two, and may be one, three, or more, as long as they can avoid the installation protrusion 112. The number of second heat dissipation fins 123 may include, but is not limited to, one, and may be two, three, or more, as long as they can meet the heat dissipation requirements. This application does not limit the number of fins in this implementation.

[0063] refer to Figure 1 , Figure 2 In this embodiment, the base plate 121 is a cuboid. In some possible embodiments, the shape of the base plate 121 is not limited to a cuboid, but can be a frustum of a cone, a cube, an irregular shape, etc., which can be adjusted according to the actual space of the headlight 200. This application does not limit this. Due to the different shapes of the base plate 121, the number of side walls of the base plate 121 is not limited to four. A first heat dissipation rib 122 or a second heat dissipation rib 123 can be provided on the outer periphery of the base plate 121. The specific adjustment can be made according to the actual heat dissipation requirements. This application does not limit this.

[0064] refer to Figure 1 , Figure 2 In this embodiment, the first heat dissipation fin 122 is a regular cuboid structure, and the second heat dissipation fin 123 is also a regular cuboid structure. In some possible embodiments, the shapes of the first heat dissipation fin 122 and the second heat dissipation fin 123 are not limited to cuboids, but can be arc-shaped, corrugated, trapezoidal, or irregular shapes, as long as the heat dissipation area can be guaranteed and it can be adapted to the internal assembly structure of the vehicle headlight 200. This embodiment does not limit this.

[0065] By setting the first heat dissipation rib 122 and the second heat dissipation rib 123 that bend upward on the base plate 121, the effective heat dissipation area of ​​the lower housing 120 is increased, thereby improving the overall heat dissipation performance of the vehicle light controller 100.

[0066] refer to Figure 1, Figure 2 , Figure 3 In this embodiment, the length L1 of the first heat dissipation fin 122 is ( Figure 3 The length L2 of the second heat dissipation fin 123 is less than that shown in L1. Figure 3 (As shown in L2).

[0067] The length L2 of the second heat dissipation rib 123 is greater than the length L1 of the first heat dissipation rib 122, meaning the second heat dissipation rib 123 is longer, thus increasing the heat dissipation area. The first heat dissipation rib 122, being shorter, effectively avoids the spatial structure of the mounting protrusion 112 described below.

[0068] In some possible implementations, the length of the first heat dissipation fin 122 may be greater than or equal to the length of the second heat dissipation fin 123, as long as the heat dissipation requirements are met. This application does not limit this aspect.

[0069] refer to Figure 1 , Figure 2 In this embodiment, the base plate 121, the first heat dissipation fin 122 and the second heat dissipation fin 123 together form a receiving area 124, which is used to receive the upper shell 110.

[0070] refer to Figure 1 , Figure 2 , Figure 3 In this embodiment, the upper housing 110 has a base 111, the shape of which is adapted to the shape of the base plate 121 and is a cuboid. In some possible embodiments, the shape of the base 111 may include, but is not limited to, a cuboid, and may be a frustum, a cube, an irregular shape, etc., which can be adjusted according to the shape of the base plate 121. This embodiment does not limit the shape of the base 111.

[0071] refer to Figure 1 , Figure 2 , Figure 3 In this embodiment, the base plate 121 is fixedly connected to the base 111, the base 111 is located in the receiving area 124, and the first heat dissipation rib 122 and the second heat dissipation rib 123 are spaced apart from the base 111.

[0072] The upper housing 110 is located within the receiving area 124, meaning that the first heat dissipation rib 122 and the second heat dissipation rib 123 are located on the same side of the base plate 121 as the upper housing 110. The first heat dissipation rib 122 and the second heat dissipation rib 123 do not occupy space on the other side of the base plate 121 in the height direction, thus making the layout of the vehicle light controller 100 compact. The first heat dissipation rib 122 and the second heat dissipation rib 123 are spaced apart from the upper housing 110 to avoid heat accumulation and ensure uniform heat dissipation of the vehicle light controller 100.

[0073] refer to Figure 3 , Figure 4A , Figure 4B , Figure 4A for Figure 3 Enlarged view of part B, Figure 4B for Figure 3 An enlarged view of part D. In this embodiment, the distance c between the first heat dissipation fin 122 and the base 111 is ( Figure 4A As shown in c), the distance is 0.5mm, and the gap d between the second heat dissipation fin 123 and the base 111 is (…). Figure 4B (As shown in d) is also 0.5mm.

[0074] In some possible implementations, the distance between the first heat dissipation fin 122 and the base 111 is not limited to 0.5mm. The distance c between them must ensure the space for the first heat dissipation fin 122 to deform due to bending, i.e., c ≥ 0.5mm, and can be 0.6mm, 0.8mm, 1mm, etc. The distance between the second heat dissipation fin 123 and the base 111 is not limited to 0.5mm. The distance d between them must ensure the space for the second heat dissipation fin 123 to deform due to bending, i.e., d ≥ 0.5mm, and can be 0.6mm, 0.8mm, 1mm, etc.

[0075] refer to Figure 3 , Figure 5 In this embodiment, the upper housing 110 further includes a connector 117, which is disposed on the base 111. Along the second direction ( Figure 5 In the Y direction, the insertion interface 117 of the upper housing 110 has an upper end face 1171. The first heat dissipation fin 122 has a first top surface 1221, and the second heat dissipation fin 123 has a second top surface 1231. Along the second direction, neither the first top surface 1221 nor the second top surface 1231 is higher than the upper end face 1171. Wherein, the Y direction is the height direction of the upper housing 110.

[0076] Specifically, the height of the upper end surface 1171 from the bottom surface 1215 of the base plate 121 is h1 ( Figure 5 As shown in h1), the height of the first top surface 1221 from the bottom surface 1215 is h2 ( Figure 5 As shown in h2), the height of the second top surface 1231 from the bottom surface 1215 is h3 ( Figure 5 (As shown in h3). Where h2≤h1, h3≤h1.

[0077] It should be noted that the upper end face 1171 of the connector 117 is the highest point of the upper housing 110.

[0078] By limiting the top height of the first heat dissipation fin 122 and the second heat dissipation fin 123 to below the upper end face 1171 of the connector 117, the overall height and shape of the headlight controller 100 are effectively reduced. This avoids spatial interference with surrounding components in the second direction, making it particularly suitable for headlights 200 with limited installation space, resulting in a more compact layout for the headlight controller 100. (Reference) Figure 6 , Figure 7 In this embodiment, the extending direction of the first heat dissipation fin 122 forms an angle α with the base plate 121. Figure 7 (As shown in a) is 90°, for reference. Figure 8 The extension direction of the second heat dissipation fin 123 forms an angle b with the base plate 121. Figure 8 (As shown in b) is 90°.

[0079] By setting the first heat dissipation rib 122 and the second heat dissipation rib 123 perpendicular to the base plate 121, that is, the first heat dissipation rib 122 and the second heat dissipation rib 123 only extend along the height direction and do not extend in the horizontal direction, the space occupied in the horizontal direction is reduced, the spatial layout of the headlight controller 100 is optimized, and thus the space occupied by the overall headlight controller 100 within the headlight 200 is reduced.

[0080] In some possible implementations, the included angle α is not limited to 90°, and the included angle α can be any degree value of 90° ≤ a < 180°, such as 100°, 120°, 145°, etc. The included angle β is not limited to 90°, and the included angle β can be any degree value of 90° ≤ b < 180°, such as 100°, 120°, 145°, etc.

[0081] The angles between the first heat dissipation fin 122, the second heat dissipation fin 123, and the base plate 121 are all set between 90° and 180°. Compared to a design with an angle less than 90°, this ensures that the base plate 121 is smaller while accommodating the upper housing 110, thus reducing the space occupied by the base plate 121. Furthermore, during vehicle operation, air flows past the headlight 200 area. The inclined design of the first heat dissipation fin 122 and the second heat dissipation fin 123 relative to the base plate 121 can adapt to changes in airflow direction caused by different headlight 200 shapes. By designing the angle, the first heat dissipation fin 122 and the second heat dissipation fin 123 can increase their frontal area, increase convective heat transfer efficiency, and improve heat dissipation efficiency.

[0082] refer to Figure 7 , Figure 8 In this embodiment, the thickness of the first heat dissipation fin 122 and the second heat dissipation fin 123 is equal to 1 mm. In some possible embodiments, the thickness e1 of the first heat dissipation fin 122 is... Figure 7 As shown in e1), the thickness e2 of the second heat dissipation fin 123 ( Figure 8As shown in e2, it is sufficient to satisfy a value greater than or equal to 1mm, such as 1.2mm, 2mm, 3mm, etc.

[0083] By setting the thickness of the first heat dissipation fin 122 and the second heat dissipation fin 123 to not less than 1mm, problems such as insufficient heat conduction cross section and small heat capacity caused by the first heat dissipation fin 122 and the second heat dissipation fin 123 being too thin can be effectively avoided.

[0084] In some possible implementations, the contact area between the first heat dissipation fin 122 and the second heat dissipation fin 123 and the airflow can be increased by providing through holes (not shown in the figure) on the first heat dissipation fin 122 and the second heat dissipation fin 123.

[0085] refer to Figure 6 , Figure 7 , Figure 8 In this embodiment, the lower housing 120 is made of aluminum alloy. In some possible embodiments, the material of the lower housing 120 may include, but is not limited to, aluminum alloy, and may also be other materials, such as magnesium alloy, copper alloy, high thermal conductivity engineering plastic, carbon material, etc.

[0086] By using aluminum alloy to manufacture the lower housing 120, the excellent thermal conductivity of aluminum alloy is fully utilized, which can quickly conduct heat from the inside of the headlight controller 100 to the surfaces of the base plate 121, the first heat dissipation fin 122, and the second heat dissipation fin 123. At the same time, aluminum alloy has the characteristics of low density, high strength, and corrosion resistance, which significantly reduces the overall weight while ensuring efficient heat dissipation.

[0087] refer to Figure 6 , Figure 7 , Figure 8 In this embodiment, the base plate 121, the first heat dissipation fin 122, and the second heat dissipation fin 123 are integrally formed, thereby eliminating the assembly gap and contact thermal resistance between parts. This not only improves the overall mechanical strength and vibration reliability of the lower housing 120, but also eliminates the contact thermal resistance caused by the assembly interface of the parts, thereby avoiding the loss of heat dissipation efficiency.

[0088] In this embodiment, after the base plate 121, the first heat dissipation rib 122, and the second heat dissipation rib 123 are integrally formed, the first heat dissipation rib 122 and the second heat dissipation rib 123 are on the same plane as the base plate 121. After the upper housing 110 is placed in the mounting position with the lower housing 120, the first heat dissipation rib 122 and the second heat dissipation rib 123 are bent upward to a preset angle by a bending process, thereby forming the vehicle light controller 100.

[0089] In some possible implementations, the base plate 121, the first heat dissipation fin 122, and the second heat dissipation fin 123 can also be connected separately, such as by welding, screwing, or riveting, as long as the heat dissipation and connection requirements are met. This application does not limit this aspect.

[0090] refer to Figure 9 In this embodiment, the base 111 has a first outer wall 113, a second outer wall 114, a third outer wall 115, and a fourth outer wall 116. A mounting protrusion 112 is provided at the center of the first outer wall 113, which is located between the second outer wall 114 and the fourth outer wall 116. The mounting protrusion 112 extends along a first direction (…). Figure 9 Extending in the X direction. A mounting protrusion 112 is used for connecting the headlight controller 100 to other components of the headlight 200. Here, the X direction is the length direction of the upper housing 110, and the X direction is perpendicular to the Y direction.

[0091] In some possible implementations, the mounting protrusion 112 may not be located in the middle of the first outer wall 113, but may be located near the second outer wall 114 or the fourth outer wall 116. The specific location may be adjusted according to the specific layout of the headlight 200.

[0092] In some possible implementations, the mounting protrusion 112 on the first outer wall 113 may include, but is not limited to, one, and can be adaptively adjusted according to the actual installation of the vehicle lamp 200, for example, there may be two, three, four, or more. In some possible implementations, the mounting protrusion 112 may also be provided on the second outer wall 114, the third outer wall 115, or the fourth outer wall 116 (not shown in the figure), and can be adaptively adjusted according to the actual layout of the vehicle lamp 200.

[0093] refer to Figure 9 In this embodiment, the first outer wall 113 has a first groove 1131 on each side of the mounting protrusion 112. The second outer wall 114 and the fourth outer wall 116 each have a second groove 1141. In some possible embodiments, the first groove 1131 may also be located on one side of the mounting protrusion 112, depending on the position of the mounting protrusion 112.

[0094] Combination Figure 1 , Figure 2 In this embodiment, the first groove 1131 corresponds one-to-one with the first heat dissipation rib 122, and the first heat dissipation rib 122 is disposed in the first groove 1131. The second groove 1141 corresponds one-to-one with the second heat dissipation rib 123, and the second heat dissipation rib 123 is disposed in the second groove 1141.
