[0002] The rapid development of the automotive industry has driven the rapid growth of the automotive lighting industry, with more and more people paying attention to the quality and performance of lighting fixtures. Automotive lights have a complex internal structure, including various electronic components and intricate wiring harnesses. The internal wiring harnesses are responsible for accurately transmitting control signals to various functional modules, ensuring that these functions operate normally.

[0003] In actual use, cars are constantly subjected to vibrations and impacts from uneven road surfaces and bumps. These vibrations and impacts are transmitted to the inside of the headlights, causing relative movement between the wiring harness and the headlight housing and other components. Prolonged and repeated friction can gradually wear down the insulation layer of the wiring harness, potentially exposing the wires. Furthermore, making electrical connections between the internal wiring harness and the external headlight is inconvenient and affects assembly efficiency.

[0004] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0030] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] The following will describe in detail the vehicle lighting module, vehicle lighting, and vehicle in this application with reference to the accompanying drawings and specific embodiments.

[0033] In existing technologies, wiring harnesses are complex and prone to wear during use. Furthermore, it is inconvenient to connect the internal wiring harness of the headlight to the external headlight, resulting in low assembly efficiency.

[0034] To address the aforementioned technical problems, this application provides a vehicle lighting module, including a lamp body, a mounting plate, and a wiring harness. The lamp body has a receiving cavity, the mounting plate is housed within the receiving cavity, and the mounting plate has a wiring groove on its surface facing the lamp body. The wiring harness is routed within the wiring groove via a fixing structure. At least one through-hole is provided on the portion of the lamp body opposite to the mounting plate surface, providing operational space for the wiring harness to be electrically connected to the outside of the lamp body.

[0035] By incorporating wiring channels on the mounting plate and routing the wiring harness within these channels, no separate components are needed for wiring harness arrangement, saving internal space in the headlight and facilitating manufacturing. The wiring harness can be neatly arranged within the channels, preventing a messy distribution within the headlight fixture. This not only makes the headlight fixture more aesthetically pleasing but also facilitates installation, maintenance, and inspection. Furthermore, the wiring harness is electrically connected to the external headlight via through-holes, ensuring easy operation and preventing the connections from easily loosening or detaching, thus guaranteeing the stability of the electrical connection. This will be explained in detail below.

[0036] See Figure 1 and Figure 2 In one embodiment, the vehicle light module includes a lamp body 10, a mounting plate 20, and a wiring harness 30; the lamp body 10 has a receiving cavity, the mounting plate 20 is received in the receiving cavity, and the mounting plate 20 has a wiring groove 21 on the plate surface facing the lamp body 10; the wiring harness 30 is arranged in the wiring groove 21 through a fixing structure 40; wherein, a connection through hole 11 is provided on the portion of the lamp body 10 opposite to the plate surface of the mounting plate 20, providing operating space for the wiring harness 30 to be electrically connected to the outside of the lamp body 10.

[0037] The wiring harness 30 is installed in the wiring trough 21 through the fixing structure 40. The wiring harness 30 can be neatly arranged in the wiring trough 21, avoiding the messy distribution of the wiring harness 30 inside the lamp. This not only makes the appearance of the lamp more neat and beautiful, but also facilitates installation, maintenance and inspection. In addition, the wiring harness 30 is confined in the wiring trough 21, and the vibration generated during vehicle movement will not cause the wiring harness 30 to move in a wide range. This reduces the friction between the wiring harness 30 and the mounting plate 20 or other components, avoids wear on the outer insulation layer of the wiring harness 30, effectively improves the service life and safety of the wiring harness 30, and ensures the stable operation of the lamp. Moreover, after the mounting plate 20 is installed on the lamp body 10, the wiring trough 21 is covered by the part of the lamp body 10 opposite to the mounting plate 20, further protecting the wiring harness 30 and preventing the wiring harness 30 from becoming loose.

[0038] A wiring channel 21 is provided on the mounting plate 20, meaning that the wiring channel 21 is part of the mounting plate 20. This eliminates the need for a separate component for arranging the wiring harness 30, saving internal space in the headlight and facilitating manufacturing. The wiring harness 30 can be fixed in the wiring channel 21 using only the fixing structure 40, improving assembly efficiency. Simultaneously, a connection through hole 11 is provided on the headlight body 10, facilitating the connection of the wiring harness 30 to the external headlight, ensuring smooth transmission of external power and control signals to the headlight. The connection through hole 11 also facilitates the installation of the wiring harness 30 to the external headlight, ensuring stability after connection and preventing loosening or detachment, thus guaranteeing the stability of the electrical connection.

[0039] It should be noted that the accommodating cavity is the internal cavity of the vehicle lamp, that is, the interior of the vehicle lamp, used to provide installation space for the installation of various components such as the light source in the vehicle lamp. The mounting plate 20 is set in the accommodating cavity, and the wiring harness 30 on the mounting plate 20 is electrically connected to the outside of the vehicle lamp through the connecting through hole 11. The connection method between the wiring harness 30 inside the vehicle lamp (i.e., the wiring harness 30 in the wiring trough 21, the same below) and the cable outside the vehicle lamp can be welding or splicing by the installer. In some embodiments, the wiring harness 30 inside the vehicle lamp can also be connected to the cable outside the vehicle lamp by setting an adapter 60 at the end of the wiring harness 30. The installer does not need to perform complicated welding or splicing operations. The setting of the adapter 60 can ensure the stability of the connection and will not easily loosen or fall off, ensuring the stability of the electrical connection, and is convenient to operate, improving installation efficiency. The method of connecting the wiring harness 30 is determined according to the needs of the actual production process.

[0040] It should also be noted that in this embodiment, there is only one connecting through hole 11, that is, the wire harness 30 is electrically connected to the external cable through an adapter 60, which improves the assembly efficiency. In some embodiments, there may be multiple connecting through holes 11, depending on the actual wiring needs of the wire harness 30. The connecting through hole 11 can also be used as a maintenance window for the wire harness 30 in the wiring trough 21, so that the maintenance inside the lamp body 10 can be achieved without disassembling the mounting plate 20 and the lamp body 10.

[0041] In one embodiment, the connecting through hole 11 is a circular through hole, and the diameter of the connecting through hole 11 is d mm, which satisfies: 60 ≤ d ≤ 100.

[0042] When connecting the internal wiring harness 30 of the vehicle headlight to the external cable of the headlight, the operator needs to insert and remove their fingers through the connection hole 11. The circular connection hole 11 has a smooth wall and will not cause scratches to the installer. Moreover, the circular connection hole 11 is conducive to the stability of the headlight body 10 structure. If the wall of the connection hole 11 has an angle (such as a square setting), when the area of ​​the connection hole 11 (the orthographic projection area of ​​the connection hole 11 on the mounting plate 20, the same below) is large, stress is prone to concentrate at the corner of the hole wall. Under the vibration generated by the vehicle driving or the action of external force, the corner is prone to breakage.

[0043] The diameter of the connecting through hole 11 is d mm, satisfying the condition: 60 ≤ d ≤ 100, such as 60, 70, 80, 90, 100, etc. When the value of d is less than 60, the area of ​​the connecting through hole 11 is small, which cannot provide sufficient operating space for the installer, is not conducive to the connection of the wire harness 30, affects the reliability of the connection of the wire harness 30, and reduces the assembly efficiency. When the value of d is greater than 100, the area of ​​the connecting through hole 11 is large, that is, the connecting through hole 11 occupies a large area of ​​the lamp body 10, which is not conducive to the stability of the lamp body 10 structure, and the lamp body 10 is prone to breakage under external force. In summary, when d is within the above range, it can ensure that the installer has sufficient operating space and the stability of the lamp body 10 structure.

[0044] It should be noted that in some embodiments, since the size of the headlight (lamp body 10) is relatively large, the corresponding value of d can also be greater than 100, which will not affect the stability of the lamp body 10 structure.

[0045] See Figure 3 and Figure 4 In one embodiment, the wire harness 30 includes a main body 31 and a plurality of branch portions 32. The main body 31 is disposed in the wiring groove 21. One end of the branch portion 32 is connected to the main body 31, and the other end is connected to a terminal block 50. The number of branch portions 32 is determined according to the number of components that need to be connected in actual use, and is not specifically limited in this embodiment.

[0046] The end of the branch 32 is connected to a terminal block 50, which facilitates the connection operation of the branch 32 (e.g., connection to a printed circuit board). The branch 32 is located outside the wiring trough 21 and has a margin of movement, which facilitates the insertion operation of the terminal block 50 when connecting it. The main body 31 is located in the wiring trough 21, which can ensure the overall stability of the wire harness 30.

[0047] In one embodiment, the fixing structure 40 includes a cable tie 41 and a buckle 42, both of which are detachably mounted on the mounting plate 20. The cable tie 41 is disposed at the connection between the branch portion 32 and the main body portion 31 to control the length of the branch portion 32. The main body portion 31 is engaged in the buckle 42.

[0048] In practical use, the main body 31 is often a single cable, which can be quickly fixed by the snap-fit ​​of the clip 42. The number of clips 42 used is determined according to the length of the main body 31. The branch section 32 is often composed of multiple cables, and the cable tie 41 can effectively bundle multiple cables together, making operation convenient. The cable tie 41 is placed at the connection between the main body 31 and the branch section 32, which can protect the stability of the connection between the branch section 32 and the main body 31 and prevent tearing at the connection due to the movement of the branch section 32 (such as the disassembly and assembly of the terminal block 50). In addition, the cable tie 41 can also control the length of the branch section 32. The position of the cable tie 41 can be set according to the required length of the branch section 32, which can prevent the branch section 32 from being too long and affecting the assembly of other components inside the headlight.

[0049] It should also be noted that the detachable connection between the cable tie 41 and the mounting plate 20, and between the buckle 42 and the mounting plate 20, in some embodiments, can be achieved by providing mounting holes on the mounting portion and providing connecting posts 411 at the bottom of the cable tie 41 and the buckle 42 (e.g., ...). Figure 5 As shown, the cable tie 41 and the mounting plate 20 are detachably connected by inserting and removing the connecting post 411 into the mounting hole.

[0050] In some embodiments, cable ties 41 can also be used to connect and fix the main body 31, and buckles 42 can also be used to connect and fix the branch 32. The selection of cable ties 41 and buckles 42 is based on the actual installation operation of the wire harness 30, and is not limited to these.

[0051] See Figure 2 In one embodiment, the end of the wiring harness 30 is provided with an adapter 60 for electrical connection to the outside of the lamp body 10.

[0052] The adapter 60 can be connected to the outside of the vehicle light through the connection through hole 11. In actual use, the adapter 60 is connected to the external connector that is compatible with it. The adapter 60 ensures a stable connection and is easy to operate, improving installation efficiency. After the internal wiring harness 30 of the vehicle light is connected to the external cable through the adapter 60, it will not easily loosen or fall off, ensuring the stability of the electrical connection.

[0053] In one embodiment, the headlight module further includes a printed circuit board disposed on the back surface of the mounting plate 20 and the wiring harness 30.

[0054] The printed circuit board and the wire harness 30 are respectively mounted on two opposite sides of the mounting plate 20. With this arrangement, the heat generated by the components (such as LED beads) on the printed circuit board is isolated by the mounting plate 20, and the heat has a smaller impact on the wire harness 30, which is beneficial to the service life of the wire harness 30. In addition, when the wire harness 30 is disassembled (installed into the wiring duct 21) or connected to the printed circuit board, the wire harness 30 will not come into contact with the components on the printed circuit board, which improves the service life of the printed circuit board.

[0055] See Figure 2 In one embodiment, the wiring channel 21 is disposed at the bottom of the mounting plate 20.

[0056] The wiring trough 21 is located at the bottom of the mounting plate 20, meaning the wiring harness 30 is installed at the bottom of the mounting plate 20. The heat generated by the components on the printed circuit board will rise, but will not affect the wiring harness 30 located at the bottom, effectively improving the service life of the wiring harness 30. In addition, when the mounting plate 20 is installed with the lamp body 10, since the wiring harness 30 is located at the bottom of the mounting plate 20, due to gravity, the wiring harness 30 will not affect the installation operation above the wiring trough 21. Furthermore, during subsequent use, even if the wiring harness 30 falls out of the wiring trough 21 under the action of external forces such as vehicle vibration (it will be blocked by the lamp body 10), it will not affect the stability and reliability of the connection between the wiring harness 30 and the printed circuit board, or between the wiring harness 30 and the external environment. When the wiring harness 30 is located at the top, if the wiring harness 30 falls out of the wiring trough 21, it will continue to fall downwards under the action of gravity, which will affect the stability of the connection between the wiring harness 30 and the printed circuit board, or between the wiring harness 30 and the external environment.

[0057] On the other hand, this application also relates to a vehicle light, including any of the aforementioned vehicle light modules.

[0058] On the other hand, this application also relates to a vehicle including the aforementioned headlights.

[0059] The technical solution provided in this application aims to save space inside the vehicle lamp by setting a wiring groove 21 on the mounting plate 20 and laying the wiring harness 30 in the mounting groove, without the need to provide a separate component for arranging the wiring harness 30, and at the same time facilitating processing and forming; the wiring harness 30 can be neatly arranged in the wiring groove 21, avoiding the wiring harness 30 being distributed messily inside the lamp, which not only makes the appearance of the lamp more neat and beautiful, but also facilitates installation, maintenance and inspection; and the wiring harness 30 is electrically connected to the outside of the vehicle lamp through the connecting through hole 11, which is convenient for operation, and the connection of the wiring harness 30 will not easily loosen or fall off, ensuring the stability of the electrical connection.
