Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, specifically to a signal light. Background Technology

[0002] As an important component of the automotive lighting system, the front signal lights are mainly used as illumination lights to indicate road conditions and other relevant driving information. Currently, the front signal lights on the market mainly have functions such as turn signals, daytime running lights, and position lights. With the increasing demands of the automotive market and the continuous development of lighting designs, the functions of automotive front signal lights on the market need to be further improved based on the existing national standards.

[0003] Currently, automotive headlights on the market mainly function as turn signals, daytime running lights, and position lights. With the continuous advancement of automotive intelligence, the functions of headlights are becoming increasingly diverse. For example, the ADS (Autonomous Driving System Light) is a dedicated signal light used to indicate that the vehicle is in autonomous driving mode. To address the issue of implementing multiple signal functions for headlights, different functions are typically separated into multiple lights, but this undoubtedly increases design costs and fails to meet the current demand for cost reduction in lighting design. Integrating multiple signal functions into a single light would lead to complex internal structure installation. Utility Model Content

Detailed Implementation

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0049] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] Reference Figures 1 to 5 This application provides a signal light fixture, including a housing 10, a first circuit board 20, a first thick-walled component module 30, and a heat sink assembly 40.

[0051] Specifically, the bottom of the housing 10 may have a support arm, through which signal lights based on the housing 10 can be installed on equipment such as vehicles.

[0052] The first circuit board 20 integrates a first signal light assembly 21, which includes at least two types of signal lights. The first signal light assembly 21 may include signal lights with functions such as turn signals, daytime running lights, position lights, and ADS lights (autonomous driving system indicator lights), enabling the signal light to have multiple functions simultaneously, facilitating information interaction between the vehicle equipped with the signal light and the surrounding environment, and improving the practical performance of the signal light.

[0053] The first thick-walled component module 30 is mounted on the housing 10. The first thick-walled component module 30 includes a first thick-walled component upper bracket 31, a first thick-walled component body 32, and a first thick-walled component lower bracket 33. The first thick-walled component body 32 is used to support the first circuit board 20. The first thick-walled component upper bracket 31, the first thick-walled component body 32, and the first thick-walled component lower bracket 33 are arranged sequentially from top to bottom. By setting the first circuit board 20, which integrates the first signal light assembly 21, on the first thick-walled component body 32, the first signal light assembly 21 can be assembled inside the first thick-walled component module 30. This allows a single signal light fixture to have multiple types of signal light functions without having to split different types of signal functions into multiple fixtures, thus saving on fixture design costs.

[0054] A heat sink assembly 40 is disposed on the lower bracket 33 of the first thick-walled component. The heat sink assembly 40 is configured to dock with the first circuit board 20 when the upper bracket 31 and the lower bracket 33 of the first thick-walled component fix the body 32 of the first thick-walled component. During the assembly of the upper bracket 31, the body 32, and the lower bracket 33 of the first thick-walled component into the first thick-walled component module 30, the heat sink assembly 40 can be directly aligned with the first circuit board 20. After the first thick-walled component module 30 is assembled, the heat sink assembly 40 can dock with the first circuit board 20 to dissipate heat from the first circuit board 20.

[0055] By using the above method, a first thick-walled component module 30 is set up, consisting of a first thick-walled component upper bracket 31, a first thick-walled component body 32, and a first thick-walled component lower bracket 33. Multiple types of signal lights are integrated on a first circuit board 20, and the first circuit board 20 integrating multiple signal lights is set on the first thick-walled component body 32. The heat sink assembly 40 is set on the first thick-walled component lower bracket 33. This not only simplifies the structure of signal lights with multiple functions and allows for a reasonable spatial layout of the signal lights, but also enables precise docking of the heat sink assembly 40 and the first circuit board 20 during the assembly of the first thick-walled component module 30. This eliminates the need to split different types of signal functions into multiple lights, reduces design costs, reduces the number of installation steps for the lights, simplifies the installation process of the internal structure of the lights, and reduces the assembly difficulty of the lights.

[0056] In one embodiment, please Figure 5 Further reference Figure 6 and Figure 7The first thick-walled component body 32 is provided with a plurality of first sub-positioning parts 321, and the first circuit board 20 is provided with a plurality of first female positioning parts 22. The first circuit board 20 can be fixed to the first thick-walled component body 32 through the first sub-positioning parts 321 and the first female positioning parts 22. The first sub-positioning parts 321 can be rod-shaped structures, and the first female positioning parts 22 can be hole-shaped structures. The first circuit board 20 can be installed on the installation position on the first thick-walled component body 32 through the first sub-positioning parts 321 and the first female positioning parts 22. In practical applications, after the first sub-positioning parts 321 and the first female positioning parts 22 are aligned, the first circuit board 20 and the first thick-walled component body 32 can be fixed by a hot riveting process, replacing the more complicated screw fastening method, which greatly reduces the assembly workload and labor intensity of the first circuit board 20 and the first thick-walled component body 32.

[0057] Of course, in other embodiments, the first sub-positioning part 321 can also be a hole-shaped structure, and the first female positioning part 22 can be a rod-shaped structure. In this form, the first sub-positioning part 321 and the first female positioning part 22 cooperate with each other to achieve the correct docking of the first circuit board 20 and the first thick-walled body 32.

[0058] Please refer to further details. Figure 8 The lower support 33 of the first thick-walled component is provided with a second sub-positioning part 331 facing the body 32 of the first thick-walled component. The radiator assembly 40 is provided with a plurality of second female positioning parts 41. The radiator assembly 40 and the first thick-walled component body 32 can be fixed by the second sub-positioning parts 331 and the second female positioning parts 41. The second sub-positioning part 331 can be a threaded seat, and the second female positioning part 41 can be a plate-like structure symmetrically arranged on both sides of the radiator assembly 40. The second female positioning part 41 can also be provided with a positioning channel 411 corresponding to the threaded seat, so that the second female positioning part 41 and the second sub-positioning part 331 can be connected by fasteners such as screws, so that the radiator assembly 40 can be installed on the lower support 33 of the first thick-walled component.

[0059] In this embodiment, a third guide post 336 can also be provided on the lower bracket 33 of the first thick-walled component. The third guide post 336 and a portion of the positioning channel 411 of the second female positioning part 41 correspond to each other. Thus, during the process of installing the heat sink assembly 40 onto the lower bracket of the first thick-walled component module 30, the heat sink assembly 40 can be guided so that the other portion of the positioning channel 411 can be aligned with the second female positioning part 331, making it easier for screws and other fasteners to pass through the positioning channel 411 and dock with the first female positioning part 321.

[0060] In one embodiment, please refer to Figures 5 to 6The upper bracket 31 of the first thick-walled member is provided with a first sub-fastener 311 at one end, and the lower bracket 33 of the first thick-walled member is provided with a first female fastener 332 that is snapped into the first sub-fastener 311. The first sub-fastener 311 can be a protrusion, and one or more first sub-fasteners 311 can be provided. The first female fastener 332 can be a sleeve adapted to the protrusion, and one or more first female fasteners 332 can be provided corresponding to the first sub-fastener 311. In use, the first sub-fastener 311 can extend into the first female fastener 332 to achieve a snap-fit ​​connection between the two.

[0061] It should be noted that in other embodiments, the first sub-fastener 311 can be a sleeve, and the first female fastener 332 can be a protrusion adapted to the sleeve. In this form, the first sub-fastener 311 and the first female fastener 332 can also satisfy the snap-fit ​​connection at one end of the upper bracket 31 and the lower bracket 33 of the first thick-walled member.

[0062] The upper bracket 31 of the first thick-walled member has a first upper connecting portion 312 at one end, the lower bracket 33 of the first thick-walled member has a first lower connecting portion 333, and the body 32 of the first thick-walled member has a first middle connecting portion 322 located between the first upper connecting portion 312 and the first lower connecting portion 333. The contact surfaces between the first upper connecting portion 312, the first lower connecting portion 333, and the first middle connecting portion 322 are all planar, and the first upper connecting portion 312, the first middle connecting portion 322, and the first lower connecting portion 333 are fixedly connected. Specifically, the first upper connecting portion 312 is located at the other end of the upper bracket 31 of the first thick-walled member opposite to the first sub-fastener 311, and the first lower connecting portion 333 is located at the other end of the lower bracket 33 of the first thick-walled member opposite to the first female fastener 332. During the assembly of the first thick-walled component module 30, the first thick-walled component body 32 is positioned between the first thick-walled component lower support 33 and the first thick-walled component upper support 31. The first male fastener 311 and the first female fastener 332 are snapped together, and the first upper connecting part 312, the first middle connecting part 322, and the first lower connecting part 333 are correspondingly connected. This allows the first thick-walled component module 30 to be fixed from both ends of the first thick-walled component upper support 31 and the first thick-walled component lower support 33. Simultaneously, the first middle connecting part 322 is positioned between the first upper connecting part 312 and the first lower connecting part 333, enabling the first thick-walled component body 32 to be connected simultaneously with the first thick-walled component upper support 31 and the first thick-walled component lower support 33, thus increasing the overall stability of the first thick-walled component module 30. In other words, the first thick-walled component module 30 utilizes a co-locking mechanism, which greatly enhances the overall vibration stability of the module. Furthermore, the contact surfaces between the first upper connecting part 312, the first middle connecting part 322, and the first lower connecting part 333 are all set as planes. That is, when the first thick-walled component module 30 is locked together, small-face contact is adopted, which not only avoids the connection gap between the above-mentioned connecting parts and improves the connection stability between the above-mentioned connecting parts, but also avoids the problem of non-fitting contact surfaces of the first thick-walled component upper bracket 31, the first thick-walled component body 32, and the first thick-walled component lower bracket 33 due to mold injection, which can reduce the processing accuracy of the first thick-walled component upper bracket 31, the first thick-walled component body 32, and the first thick-walled component lower bracket 33 to a certain extent.

[0063] In this embodiment, please continue to refer to Figures 5 to 7The first upper connecting portion 312 is provided with a second upper connecting channel 3121, the first middle connecting portion 322 is provided with a second middle connecting channel 3221, and the first lower connecting portion 333 is provided with a second lower connecting seat 3331. The second upper connecting channel 3121, the second middle connecting channel 3221, and the second lower connecting seat 3331 are connected by a fastener. Specifically, the second upper connecting channel 3121 can be a hole-like structure provided on the first upper connecting portion 312, the second middle connecting channel 3221 can be a hole-like structure provided on the first middle connecting portion 322, and the second lower connecting seat 3331 can be a threaded seat provided on the first lower connecting portion 333. After passing screws or other fasteners through the second upper connecting channel 3121 and the second middle connecting channel 3221 respectively, they can be connected to the second lower connecting seat 3331 to achieve a fixed connection between the first upper connecting portion 312, the first middle connecting portion 322, and the first lower connecting portion 333.

[0064] Furthermore, a first upper guide channel 3122 may be provided on the first upper connecting part 312, a first middle guide channel 3222 may be provided on the first middle connecting part 322, and a first guide post 3332 may be provided on the first lower connecting part 333. Both the first upper guide channel 3122 and the first middle guide channel 3222 can be hole-like structures. When assembling the first upper connecting part 312, the first middle connecting part 322, and the first lower connecting part 333, the first guide post 3332 can pass through the first upper guide channel 3122 and the first middle guide channel 3222 to assist the second upper connecting channel 3121, the second middle connecting channel 3221, and the second lower connecting seat 3331 in achieving alignment. This not only reduces the assembly difficulty of the above-mentioned connecting parts, but also, in conjunction with the fixing components, enhances the connection strength of the first thick-walled component module 30 at one end of the first upper connecting part 312, the first middle connecting part 322, and the first lower connecting part 333.

[0065] In one embodiment, please Figure 6 , Figure 7 Further reference Figure 9 and Figure 10 The first thick-walled component upper support 31 is provided with a first upper assembly portion 313 facing away from the first thick-walled component body 32, and the housing 10 is provided with a first upper assembly seat 11. The first upper assembly portion 313 and the first upper assembly seat 11 are connected by a fastener. The first upper assembly portion 313 may be a plate-like structure integrally connected to the first thick-walled component upper support 31, and the first upper assembly seat 11 may be a threaded seat provided on the housing 10. When the first thick-walled component module 30 is installed in the housing 10, the first upper assembly portion 313 and the first upper assembly seat 11 are aligned, and the fastener is connected by passing through the first upper assembly portion 313 and the first upper assembly seat 11 to install the first thick-walled component module 30 in the housing 10 from above.

[0066] The lower support 33 of the first thick-walled component is provided with a first lower assembly portion 334 facing away from the body 32 of the first thick-walled component, and the housing 10 is provided with a first lower assembly seat 12. The first lower assembly portion 334 and the first lower assembly seat 12 are connected by a fastener. The first lower assembly portion 334 may also be a plate-like structure integrally connected to the lower support 33 of the first thick-walled component, and the first lower assembly seat 12 may also be a threaded seat provided on the housing 10. When the first thick-walled component module 30 is installed in the housing 10, the first lower assembly portion 334 and the first lower assembly seat 12 are aligned, and the fastener is passed through the first lower assembly portion 334 and the first lower assembly seat 12 to connect them, so that the first thick-walled component module 30 is installed in the housing 10 from below.

[0067] In addition, in other embodiments, please refer to Figure 5 , Figure 7 , Figure 9 and Figure 10 The first thick-walled component body 32 may also be provided with a first intermediate assembly portion 325 facing the first thick-walled component lower support 33. The first intermediate assembly portion 325 may be a plate-shaped structure integrally connected to the first thick-walled component body 32. During the connection process between the first thick-walled component body 32 and the first thick-walled component lower support 33, the first intermediate assembly portion 325 may pass through the first thick-walled component lower support 33 and correspond to and fit with the first lower assembly portion 334, so that the fastener can be installed on the first lower assembly seat 12 by passing through the first lower assembly portion 334 and the first intermediate assembly portion 325 at the same time, thereby improving the overall connection integrity of the first thick-walled component body 32, the first thick-walled component lower support 33, and the housing 10.

[0068] It should be noted that, in this embodiment, a portion of the first lower assembly part 334 can be attached to the first middle assembly part 325 and fixed together on the first lower assembly base 12.

[0071] In one embodiment, please Figure 2 and Figure 5 Further reference Figures 11 to 13 The signal lighting fixture also includes a second circuit board 50, which integrates a second signal light assembly 51. A driver chip assembly 23 is integrated on the first circuit board 20. The second circuit board 50 and the first circuit board 20 are electrically connected via an internal wiring harness 53. The second signal light assembly 51 can also integrate signal lights with multiple functions similar to the first signal light assembly 21. The first circuit board 20 is provided with a first internal terminal, and the second circuit board 50 is provided with a second internal terminal. The internal wiring harness 53 has plugs at both ends that are adapted to the first and second internal terminals, respectively, allowing the first circuit board 20 and the second circuit board 50 to be connected via the internal wiring harness 53, thereby controlling the opening and closing of the first and second signal light assemblies 21.

[0072] It should be noted that the driver chip assembly 23 may include multiple driver chips, the heat sink assembly 40 may include multiple heat sinks, and a heat conductor 42 may be provided between the heat sink and the driver chip to improve the heat dissipation effect of the heat sink on the driver chip.

[0073] The first circuit board 20 is electrically connected to external components via an external wiring harness 24. The first circuit board 20 is also provided with an external terminal block, and the external wiring harness 24 is provided with a plug adapted to the external terminal block. The external wiring harness 24 can be electrically connected to external components to realize the power input and control of the first circuit board 20.

[0074] In one embodiment, please refer to Figures 9 to 13 The signal lighting fixture also includes a second thick-walled component module 60, which is mounted on the housing 10. The second thick-walled component module 60 includes a second thick-walled upper bracket 61, a second thick-walled body 62, and a second thick-walled lower bracket 63. A second circuit board 50 is mounted on the second thick-walled body 62. Specifically, the second circuit board 50 is disposed on the second thick-walled body 62. By setting up the second thick-walled component module 60, which consists of the second thick-walled upper bracket 61, the second thick-walled body 62, and the second thick-walled lower bracket 63, multiple types of signal lights are integrated onto the second circuit board 50. This not only simplifies the structure of signal lighting fixtures with multiple functions and allows for a more rational spatial layout, but also eliminates the need to separate different types of signal functions into multiple fixtures, reducing design costs, simplifying installation steps, and reducing the difficulty of assembling the internal structure of the fixture.

[0075] In one embodiment, please refer to Figures 11 to 13 The second thick-walled component body 62 is provided with a plurality of third sub-positioning parts 621, and the second circuit board 50 is provided with a plurality of third female positioning parts 52. The second circuit board 50 and the second thick-walled component body 62 can be fixed by the third sub-positioning parts 621 and the third female positioning parts 52. Specifically, the third sub-positioning parts 621 can be rod-shaped structures, and the third female positioning parts 52 can be hole-shaped structures. The second circuit board 50 can be installed on the second thick-walled component body 62 at the installation position. In practical applications, after the third sub-positioning parts 621 and the third female positioning parts 52 are aligned, the second circuit board 50 and the second thick-walled component body 62 can be fixed by a hot riveting process, replacing the more complex screw fastening method, which greatly reduces the assembly workload and labor intensity of the second circuit board 50 and the second thick-walled component body 62.

[0076] In one embodiment, please refer to Figures 11 to 13The second thick-walled component lower support 63 has a second lower connecting portion 631 at one end, and the second thick-walled component upper support 61 has a second upper connecting portion 611 at one end.

The contact surfaces between the second upper connecting portion 611, the second middle connecting portion 622, and the second lower connecting portion 631 are all planar. The second upper connecting portion 611, the second middle connecting portion 622, and the second lower connecting portion 631 are fixedly connected. Specifically, by placing the second middle connecting portion 622 between the second upper connecting portion 611 and the second lower connecting portion 631, the second thick-walled component body 62 can be connected simultaneously with the second thick-walled component upper support 61 and the second thick-walled component lower support 63, thus improving the overall stability of the second thick-walled component module 60. That is, the second thick-walled component module 60 adopts a co-locking method, which greatly enhances the overall vibration stability of the module. Furthermore, the contact surfaces between the second upper connecting part 611, the second middle connecting part 622, and the second lower connecting part 631 are all set as planes. That is, when the second thick-walled component module 60 is locked together, small-face contact is used, which not only avoids the connection gap between the above-mentioned connecting parts and improves the connection stability between the above-mentioned connecting parts, but also avoids the problem of non-fitting contact surfaces of the second thick-walled component upper bracket 61, the second thick-walled component body 62, and the second thick-walled component lower bracket 63 due to mold injection, which can reduce the processing accuracy of the second thick-walled component upper bracket 61, the second thick-walled component body 62, and the second thick-walled component lower bracket 63 to a certain extent.

[0077] The upper bracket 61 of the second thick-walled component is fixedly connected to the body 62 of the second thick-walled component near its other end. Specifically, the upper bracket 61 of the second thick-walled component is provided with a fourth upper connecting channel 613 near one end away from the second upper connecting part 611, and the body 62 of the second thick-walled component is provided with a second middle connecting seat 626.

When assembling the second upper connecting part 611, the second middle connecting part 622, and the second lower connecting part 631, the second guide post 6312 can pass through the second upper guide channel 6112 and the second middle guide channel 6222 to assist the third upper connecting channel 6111, the third middle connecting channel 6221, and the third lower connecting seat 6311 in achieving alignment. This not only reduces the assembly difficulty of the above-mentioned connecting parts, but also, in conjunction with the fixing components, enhances the connection strength of the second thick-walled component module 60 at one end of the second upper connecting part 611, the second middle connecting part 622, and the second lower connecting part 631.

[0080] In other embodiments, please continue to refer to Figures 11 to 13 The second thick-walled component body 62 is provided with a fourth connecting channel 625, and the second thick-walled component lower bracket 63 is provided with a fourth lower connecting seat 633.

When the second thick-walled component module 60 is installed in the housing, the third middle assembly part 624 passes through the second thick-walled component lower bracket 63 and fits against the second lower assembly part 632. The fitted third middle assembly part 624, the second lower assembly part 632, and the second lower assembly seat 14 are aligned. The fastener passes through the third middle assembly part 624 and the second lower assembly part 632 and connects to the second lower assembly seat 14 so as to install the second thick-walled component module 60 in the housing 10 from below.

[0083] In one embodiment, please Figure 9 and Figure 10 Further reference Figure 14 and Figure 15The signal light also includes a decorative ring 70, with at least two third lower assembly parts 71 at its bottom.

Specifically, the third lower assembly part 71 can be a plate-like structure integrally connected to the decorative ring 70, or it can be a threaded seat. When the decorative ring 70 is installed inside the housing, parts of the third lower assembly parts 71 and the third lower assembly seat 15 face each other, and the fasteners can fix the bottom of the decorative ring 70 to the housing 10. Parts of the third lower assembly parts 71 and the first lower assembly part 334 face each other, so that parts of the first middle assembly part 325 and the first lower assembly part 334 of the first thick-walled module 30, along with the third lower assembly parts 71, can be fixed inside the housing 10 by the fasteners. Thus, while connecting the bottom of the decorative ring 70 to the housing 10, it provides multiple forms of assembly fit between the decorative ring 70 and the housing 10, thereby improving the stability of the assembly of the housing 10, the decorative ring 70, and the second thick-walled module 60.

[0084] It should be noted that auxiliary guide channels can also be provided on the decorative ring 70, and auxiliary guide posts corresponding to the auxiliary guide channels can be provided on the housing 10. When the auxiliary guide posts move along the auxiliary guide channels, the third lower assembly part 71 can be aligned with the third lower assembly seat 15 and part of the first assembly seat. This can reduce the assembly difficulty of the decorative ring 70.

[0085] In one embodiment, please Figure 9 and Figure 10 Further reference Figure 14 The decorative ring 70 is provided with a third upper assembly seat 72, and the housing 10 is provided with a third upper assembly part 18.

When the faceplate 90 is connected to the housing, the peripheral assembly seat 91 and the peripheral assembly part 16 face each other, and the faceplate 90 and the housing 10 can be fixed from the back of the housing 10 by the fastener. Therefore, by fixing the faceplate 90 from the back of the housing 10 by a fastener, screws and other fasteners are avoided from protruding from the edge of the faceplate 90, which would affect the overall aesthetics of the signal light fixture.

[0088] In this embodiment, a second sub-fastener 92 can be provided around the face mask 90, and a second female fastener 17 can be provided around the housing 10. The first sub-fastener 311 can be a protrusion on the edge of the face mask 90, and multiple first sub-fasteners 311 can be provided.
