[0002] With the development of the automotive industry, higher requirements have been placed on the stability of vehicle lights. The reliable fixing of the internal light source components of vehicle lights has become a key factor affecting the overall performance of vehicle lights.

[0003] In related technologies, clips are used to fix the light source components inside the headlight. However, when the headlight is subjected to external force or vibration, the light source components and clips are prone to separation, affecting the light output performance of the headlight. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a vehicle lamp and a vehicle, wherein the light source assembly can be indirectly fixed to the housing through a connector, and the stop protrusion can prevent the corresponding hook from disengaging from the light source assembly, so as to make the setting position of the light source assembly more stable and improve the stability of the vehicle lamp operation.

[0005] According to a first aspect of the present invention, a vehicle lamp includes: a housing, a light source assembly, and at least one connector. The housing has a mounting cavity, the light source assembly is disposed in the mounting cavity, and includes a circuit board and a light source. The circuit board has a mating part and at least one mating through hole. The mating part is located at the edge of the circuit board and is engaged with the housing in the thickness direction of the circuit board. The mating through hole is spaced apart from the edge of the circuit board. The light source is disposed on the circuit board and is spaced apart from the mating part and the mating through hole. The connector is disposed in the mounting cavity and includes a main body, a stop protrusion, and at least one hook. The main body is disposed on one side of the thickness of the circuit board and is fixedly connected to the housing.

The stop protrusion is disposed on the main body and abuts against the opposite sides of the hole wall of the mating through hole, respectively, with the hook, to prevent the corresponding hook from disengaging from the mating through hole.

[0006] According to an embodiment of the present invention, the vehicle lamp connector includes a main body, a stop protrusion, and at least one hook. The main body is located on one side of the thickness of the circuit board and is fixedly connected to the housing. The hook can be engaged through a mating through-hole on the circuit board on the side of the mating through-hole away from the main body.

[0036] Hereinafter, with reference to the accompanying drawings, a vehicle light 100 according to a first aspect embodiment of the present invention will be described.

[0037] like Figures 1-6 As shown, the vehicle headlight 100 includes: a housing 1, a light source assembly 2, and at least one connector 3. The housing 1 has a mounting cavity 10, and the light source assembly 2 is disposed within the mounting cavity 10. The light source assembly 2 includes a circuit board 20 and a light source 23. The circuit board 20 has a mating portion 21 and at least one mating through hole 22. The mating portion 21 is located at the edge of the circuit board 20, and the mating portion 21 and the housing 1 are in the thickness direction of the circuit board 20 (e.g., ...). Figure 4The upper limit of the thickness direction of the circuit board 20 is matched. The through hole 22 is spaced apart from the edge of the circuit board 20. The light source 23 is set on the circuit board 20 and is spaced apart from the mating part 21. The light source 23 is also spaced apart from the mating through hole 22. The connector 3 is set in the mounting cavity 10 and includes a main body 30, a stop protrusion 31 and at least one hook 32. The main body 30 is set on the thickness side of the circuit board 20 and is fixedly connected to the housing 1. The hook 32 is set on the main body 30 and passes through the corresponding mating through hole 22. The hook 32 is hooked on the edge of the mating through hole 22 away from the main body 30. The stop protrusion 31 is set on the main body 30 and the stop protrusion 31 and the hook 32 respectively abut against the opposite sides of the hole wall of the mating through hole 22 to prevent the corresponding hook 32 from disengaging from the mating through hole 22.

[0038] As can be seen, the connector 3 includes a main body 30, a stop protrusion 31, and at least one hook 32. The main body 30 is located on the thickness side of the circuit and is fixedly connected to the housing 1 so that the connector 3 is stably installed in the mounting cavity 10. At least one mating through hole 22 is formed on the circuit board 20. The hook 32 can pass through the mating through hole 22 and is hooked on the edge of the mating through hole 22 away from the main body 30. That is, a part of the hook 32 (e.g., the hook portion 32b described later) and the main body 30 are located on both sides of the thickness of the circuit board 20. At the same time, a mating portion 21 is also formed on the circuit board 20. The connector 31 can be positioned and engaged with the housing 1 in the thickness direction to prevent the circuit board 20 from moving along its thickness direction. The stop protrusion 31 can abut against the side of the hole wall of the mating through hole 22 away from the hook 32. In the direction opposite to the hook 32 and the stop protrusion 31, due to the abutment of the stop protrusion 31, the stop protrusion 31 can restrict the hook 32 from moving relative to the circuit board 20 in the direction of disengagement from the mating through hole 22. This makes it easy for the hook 32 to always be hooked on the edge of the mating through hole 22 away from the main body 30. The hook 32 is not easy to disengage from the edge of the mating through hole 22, thus improving the reliability of the fit between the connector 3 and the circuit board 20.

[0039] For example, taking the stop protrusion 31 and the corresponding hook 32 as being arranged opposite each other in the first direction, the stop protrusion 31 and the corresponding hook 32 respectively abut against the hole wall of the mating through hole 22 on both sides in the first direction, and the stop protrusion 32 abuts against the hole wall of the mating through hole 22 in the first direction, and the corresponding hook 32 abuts against the hole wall of the mating through hole 22 in the first direction.

[0040] Therefore, the light source component 2 can be indirectly fixed to the housing 1 through the connector 3, and the stop protrusion 31 can restrict the corresponding hook 32 from disengaging from the light source component 2. Even when the vehicle lamp 100 is subjected to external force or vibration, the light source component 2 is not easy to disengage from the connector 3, so that the setting position of the light source component 2 is more stable, and the vehicle lamp 100 can have a more stable light output effect, which is conducive to improving the stability of the vehicle lamp 100 operation.

[0041] Furthermore, the mating part 21 is located at the edge of the circuit board 20 so that it does not easily affect the arrangement of other structures on the circuit board 20. At the same time, the mating through hole 22 is spaced apart from the edge of the circuit board 20, so that the mating through hole 22 and the mating part 21 are spaced apart, making it less likely for the mating part 21 to interfere with the connector 3, which facilitates the assembly of the vehicle lamp 100. Moreover, the edge area of ​​the circuit board 20 is limited and mated with the housing 1, so the edge area of ​​the circuit board 20 can be supported to a certain extent. Other areas of the circuit board 20, except for the edge area, do not need to be mated with the housing 1 and can be suspended. When the size of the circuit board 20 is large (e.g., the length of the circuit board 20 is long), the connector 3 can reliably limit and support the areas of the circuit board 20 that are not supported by the housing 1 (e.g., the suspended areas of the circuit board 20), which facilitates the reliable installation of the entire circuit board 20, improves the installation stability of the circuit board 20, reduces the risk of the circuit board 20 shaking or deforming, and improves the performance of the vehicle lamp 100. In other words, the embodiments of this application can be applied to the case of a large size circuit board 20. Of course, this does not mean that the embodiments of this application have limitations on the size of the circuit board 20.

[0042] The light source 23 is spaced apart from the mating part 21 and the mating through hole 22 so that the mating part 21 and the mating through hole 22 are not likely to affect the light source 23 after they are assembled with other components, and other components are not likely to block the light source 23.

[0043] It is understood that the connector 3 may include one or more hooks 32, each hook 32 corresponding to a mating through hole 22. Multiple hooks 32 restrict the circuit board 20 to improve the mating strength between the connector 3 and the light source assembly 2. The vehicle lamp 100 may include one or more connectors 3, which may mat with the same light source assembly 2 or with different light source assemblies 2. Multiple mating through holes 22 may be formed on the circuit board 20, and these holes may correspond one-to-one with the multiple hooks 32 on all connectors 3. The stop protrusion 31 may be one or more. For example, in... Figure 5 In the example, connector 3 includes two hooks 32 and a stop protrusion 31.

[0044] like Figures 4-6As shown, in some embodiments, the main body 30 is abutted against the circuit board 20. The hook 32 includes an arm 32a and a hook 32b. The arm 32a passes through the mating through hole 22 and abuts against the wall of the mating through hole 22 in a first direction. The hook 32b protrudes from one side of the arm 32a in the first direction. The stop protrusions 31 are spaced apart on the side of the arm 32a away from the hook 32b. The arm 32a and the mating through hole 22 are engaged in a limit engagement in a second direction. The first direction, the second direction, and the thickness direction of the circuit board 20 are perpendicular to each other.

[0045] As can be seen, the main body 30 and the circuit board 20 are abutted together, and the hook 32 passes through the corresponding mating through hole 22. The hook 32 is hooked on the side edge of the mating through hole 22 away from the main body 30, that is, the hook part 32b is hooked on the side edge of the mating through hole 22, so that the main body 30 and the hook part 32b are abutted together on both sides of the thickness of the circuit board 20, which can restrict the movement of the circuit board 20 in the thickness direction, making it difficult for the circuit board 20 to detach from the hook 32 along its thickness direction, and further enhancing the mating strength of the connector 3 and the light source assembly 2.

[0046] Furthermore, the arm portion 32a abuts against the wall of the through hole 22 in the first direction, and the stop protrusion 31 is spaced apart on the side of the arm portion 32a away from the hook portion 32b. That is, in the first direction, the arm portion 32a and the stop protrusion 31 abut against the opposite sides of the wall of the through hole 22 to restrict the movement of the circuit board 20 in the first direction, making it difficult for the circuit board 20 to disengage from the hook 32 in the first direction. At the same time, the arm portion 32a and the through hole 22 are engaged in an upper limit engagement in the second direction, so that after the arm portion 32a engages with the through hole 22, it can restrict the movement of the circuit board 20 in the second direction, making it difficult for the circuit board 20 to move in the second direction. This enhances the engagement stability of the connector 3 and the light source assembly 2, enhances the setting stability of the circuit board 20, and facilitates the improvement of the operational stability of the vehicle lamp 100. The first direction, the second direction, and the thickness direction of the circuit board 20 are perpendicular to each other. By setting the connector 3, the movement of the light source assembly 2 along the first direction, the second direction, and the thickness direction of the circuit board 20 can be restricted, so that the setting position of the light source 23 is more stable, which facilitates the improvement of the stability of the vehicle lamp 100 operation.

[0047] like Figures 4-6As shown, in some embodiments, the through hole 22 includes a first hole portion 22a and a second hole portion 22b arranged sequentially along a first direction. The arm portion 32a is limited to the first hole portion 22a, and the arm portion 32a is limited to the second hole portion 22a in a second direction. The arm portion 32a and the hole wall of the second hole portion 22a are abutted in the first direction. The stop protrusion 31 abuts against the hole wall of the second hole portion 22b, and the stop protrusion 31 is abutted to the hole wall of the second hole portion 22b in the first direction. In the second direction, the size of the first hole portion 22a is smaller than the size of the second hole portion 22b.

[0048] As can be seen, in the second direction, the size of the first hole 22a is smaller than the size of the second hole 22b, so that after the hook 32 engages with the through hole 22, the arm 32a can abut against the two side walls of the first hole 22a in the second direction, thereby restricting the movement of the circuit board 20 in the second direction and making the setting position of the light source assembly 2 more stable.

[0049] Furthermore, the hook 32 can be first inserted into the second hole 22b, and the hook 32 can slide into the first hole 22a along the second hole 22b in the first direction until the arm 32a is engaged with the first hole 22a. At the same time, the stop protrusion 31 abuts against the hole wall of the second hole 22b. The first hole 22a and the second hole 22b provided above provide more operating space for the assembly of the hook 32, reducing the assembly difficulty of the connector 3 and the light source assembly 2. That is, the hook 32 does not need to be precisely aligned with the first hole 22a for insertion. During the assembly process, the arm 32a of the hook 32 can slide smoothly into the first hole 22a, which facilitates the improvement of the assembly efficiency of the vehicle lamp 100.

[0050] like Figures 3-6 As shown, in some embodiments, the vehicle light 100 is configured to satisfy at least one of the following conditions A1 to A4:

[0051] In condition A1, the main body 30 is cantilevered and has a fixed end 30a and a free end 30b arranged opposite to each other along a first direction. The fixed end 30a is fixed to the housing 1, and the stop protrusions 31 are spaced apart on the side of the corresponding hook 32 adjacent to the free end 30b in the first direction. The first direction is perpendicular to the thickness direction of the circuit board 20.

[0052] As can be seen, the stop protrusions 31 are spaced apart on the side of the hook 32 adjacent to the free end 30b in the first direction. That is, relative to the hook 32, the stop protrusions 31 are further away from the fixed end 30a, so that the area where the stop protrusions 31 are located can be deformed relatively more easily. When the connector 3 is fitted to the circuit board 20, the hook 32 can be inserted into the mating through hole 22 first. At this time, a certain force can be applied to the area where the stop protrusions 31 are located, so that the stop protrusions 31 can move away from the mating through hole 22, so that the stop protrusions 31 are less likely to interfere with the circuit board 20. After at least part of the hook 32 is abutted against the hole wall of the mating through hole 22, the force applied to the area where the stop protrusions 31 are located is stopped, so that the hook 32 and the stop protrusions 31 are abutted against the opposite sides of the hole wall of the mating through hole 22. This facilitates the assembly of the connector 3 and the light source assembly 2. The setting of the stop protrusion 31 reduces the difficulty of assembling the connector 3 and the light source assembly 2, and improves the assembly efficiency of the vehicle lamp 100.

[0053] In condition A2, the main body 30 is cantilevered and has a fixed end 30a and a free end 30b arranged opposite each other along a first direction. The fixed end 30a is positioned and engaged with the housing 1 through a positioning structure 4. The positioning structure 4 includes a positioning protrusion 40 and a positioning groove 41. The positioning protrusion 40 protrudes along the first direction, so the positioning protrusion 40 and the positioning groove 41 can be inserted into each other along the first direction. The main body 30 is provided with a fastener 5, which passes through the positioning protrusion 40 to fix the main body 30 and the housing 1. The first direction is perpendicular to the thickness direction of the circuit board 20. It can be understood that the fixed end 30a refers to the end of the main body 30 that is fixed to the housing 1, and the free end 30b refers to the end of the main body 30 that is not fixed to the housing 1.

[0054] As can be seen, the fixed end 30a is positioned and engaged with the housing 1 through the positioning structure 4. For example, the positioning protrusion 40 is located on the housing 1 and the positioning groove 41 is located on the fixed end 30a, or the positioning protrusion 40 is located on the fixed end 30a and the positioning groove 41 is located on the housing 1. By positioning and engaging the positioning protrusion 40 in the positioning groove 41, the positioning engagement of the housing 1 and the fixed end 30a can be achieved, which facilitates the pre-positioning of the connector 3. Then, the fastener 5 is inserted through the positioning protrusion 40 to fix the fixed end 30a of the main body 30 and the housing 1, so that the setting position of the connector 3 is more stable, which facilitates the improvement of the stability of the vehicle lamp 100 operation. At the same time, the above-mentioned positioning structure 4 can simplify the assembly process of the housing 1 and the connector 3, which facilitates the improvement of the assembly efficiency of the vehicle lamp 100.

[0055] For example, such as Figure 4 and Figure 5 As shown, a positioning groove 41 is formed on the fixed end 30a. The opening of the positioning groove 41 is set towards the positioning protrusion 40. The peripheral wall of the positioning groove 41 can be extended into a closed ring or an open ring.

[0056] Optionally, the fastener 5 is configured to allow the connector 3 and the housing 1 to be detachably installed, for example, the fastener 5 is a threaded fastener (such as a screw), so that the installation and removal of the connector 3 and the housing 1 are more convenient, facilitating subsequent maintenance and repair, while making the overall structure more compact and saving space.

[0057] In condition A3, the dimensions of circuit board 20 in the first direction (e.g.) Figure 3 L2) is smaller than its dimension in the second direction (e.g. Figure 3 In L1), there are multiple hooks 32, with at least two hooks 32 spaced apart along the first direction. Stop protrusions 31 are spaced apart on one side of the corresponding hooks 32 in the first direction. The first direction is perpendicular to the thickness direction of the circuit board 20. The first direction, the second direction, and the thickness direction of the circuit board 20 are perpendicular to each other.

[0058] As can be seen, the connector 3 includes multiple hooks 32, and the circuit board 20 also has multiple mating through holes 22. Each hook 32 can be mated with the corresponding mating through hole 22, so that multiple hooks 32 can support the circuit board 20 at different positions, reducing the limitation on the size of the circuit board 20 in the first direction. Even if the size of the circuit board 20 in the first direction is large, multiple hooks 32 can still support the circuit board 20 well, so that the circuit board 20 is not prone to shaking, local collapse and other problems, making the setting position of the light source assembly 2 more stable, and facilitating the improvement of the light output stability of the vehicle lamp 100.

[0059] The stop protrusions 31 are spaced apart on one side of the hooks 32 in the first direction, so that after the circuit board 20 is engaged with the multiple hooks 32, the circuit board 20 is less likely to detach from the multiple hooks 32 in the first direction, thereby improving the stability of the vehicle light 100. For example, for a single connector 3, the number of stop protrusions 31 can be less than or equal to the number of hooks 32.

[0060] Of course, in other embodiments of this application, some hooks 32 may also be spaced apart along the second direction so that multiple hooks 32 are arranged in multiple rows and columns to further enhance the fit between the connector 3 and the light source assembly 2.

[0061] In condition A4, the main body 30 is detachable. When the connector 3 and the light source assembly 2 are assembled, the main body 30 can be separated from the housing 1 first, and then the circuit board 20 can be assembled into the housing 1. Then, the hook 32 of the connector 3 can be assembled into the circuit board 20, and the stop protrusion 31 can be assembled into the through hole 22. This makes it less likely for the connector 3 and the light source assembly 2 to interfere with each other during assembly. At the same time, when it is necessary to maintain or replace the light source assembly 2, the main body 30 can be disassembled from the housing 1, and the connector 3 and the light source assembly 2 can be disassembled together, which facilitates the subsequent maintenance of the vehicle light 100.

[0062] like Figures 4-6 As shown, in some embodiments, the vehicle lamp 100 is configured to satisfy condition A1. The stop protrusion 31 is positioned near the free end 30b. In the first direction, the hook 32 corresponding to the stop protrusion 31 is also positioned closer to the free end 30b. The fixed end 30a of the main body 30 is fixedly connected to the housing 1. Through the arrangement of the stop protrusion 31 and the hook 32, the support range of the connector 3 for the light source assembly 2 can be increased, allowing the light source assembly 2 to receive more stable support. This prevents the light source assembly 2 from shaking or collapsing, thus improving the stability of the vehicle lamp 100. Furthermore, the proximity of the stop protrusion 31 to the free end 30b further enhances the deformation capacity of the area where the stop protrusion 31 is located. This allows the area where the stop protrusion 31 is located to move away from the circuit board 20 under a certain force when the connector 3 is fitted to the circuit board 20, making the assembly of the connector 3 and the light source assembly 2 more convenient and improving the assembly efficiency of the vehicle lamp 100.

[0063] like Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the main body 30 includes a first portion 33 and a second portion 34 connected along a first direction. The first portion 33 defines a fixed end 30a, and the second portion 34 defines a free end 30b. In the first direction, the length of the first portion 33 is greater than the length of the second portion 34, and the thickness of the first portion 33 is greater than the thickness of the second portion 34. All hooks 32 are provided in the first portion 33, and the stop protrusion 31 is provided in the second portion 34.

[0064] As can be seen, in the first direction, the length of the first part 33 is greater than the length of the second part 34, and the thickness of the first part 33 is greater than the thickness of the second part 34, so that the first part 33 can have better structural strength. The fixed end 30a is formed in the first part 33, so that the fit between the fixed end 30a and the housing 1 is more stable, and the setting position of the connector 3 is more stable, which facilitates the improvement of the stability of the vehicle lamp 100 operation.

[0065] The hook 32 is located on the first part 33 to provide better connection strength between the hook 32 and the first part 33. The area where the hook 32 is located is less prone to large deformation, making the fit between the hook 32 and the mating through hole 22 more stable. This makes the setting position of the light source assembly 2 more stable, which helps to improve the stability of the vehicle lamp 100 operation. The stop protrusion 31 is located on the second part 34. The second part 34 has a weaker structural strength, so that the operator can apply a small force to the second part 34 to keep the stop protrusion 31 away from the circuit board 20. This makes it less likely for the connector 3 and the circuit board 20 to interfere with the stop protrusion 31 during assembly, which helps to improve the assembly efficiency of the vehicle lamp 100.

[0066] For example, when the connector 3 is assembled onto the circuit board 20, the hook 32 can be inserted into the mating through hole 22 first. At this time, a certain force can be applied to the second part 34 so that the stop protrusion 31 can have a certain distance from the mating through hole 22, so that the stop protrusion 31 is less likely to interfere with the circuit board 20. The connector 3 is pushed along the first direction until the hook 32 stops and engages with the hole wall of the mating through hole 22. Then, the force applied to the second part 34 is stopped, so that the hook 32 and the stop protrusion 31 are respectively engaged with the hole wall of the mating through hole 22 on opposite sides in the first direction. This facilitates the assembly of the connector 3 and the light source assembly 2. By setting the second part 34, the area where the stop protrusion 31 is located can be deformed more easily, which reduces the difficulty of assembling the connector 3 and the light source assembly 2 and improves the assembly efficiency of the vehicle lamp 100.

[0067] like Figure 4 and Figure 7 As shown, in some embodiments, the surface of the second part 34 facing away from the stop protrusion 31 is formed as a concave surface 30c that is recessed toward the side where the stop protrusion 31 is located. For example, the thickness of the middle region of the second part 34 is less than the thickness of the edge region of the second part 34, so that when a force is applied to the second part 34, the deformation mainly occurs in the thinner middle region, while the edge region is relatively thicker and stronger, which can play a certain role in restraining and guiding the deformation, so that the deformation is carried out in a predetermined direction and manner, avoiding irregular and uncontrollable deformation, so that the force is less likely to interfere with the engagement of the hook 32 and the mating through hole 22, which facilitates the improvement of the assembly efficiency of the vehicle lamp 100; and / or, the first part 33 includes a first plate part 33a, a second plate part 33b and two third plate parts 33c arranged opposite each other along the second direction, the first plate part 33a is stacked with the circuit board 20 along the thickness direction of the circuit board 20, the second The plate portion 33b and the two third plate portions 33c are all bent and connected to the edge of the first plate portion 33a away from the circuit board 20. The second plate portion 33b is connected to one end of the first plate portion 33a in the first direction and is connected to the housing 1. Each third plate portion 33c is connected to the second plate portion 33b, that is, each third plate portion 33c is connected to the first plate portion 33a and the second plate portion 33b, so as to enhance the structural strength of the connector 3, so that the part of the first plate portion 33a away from the second plate portion 33b is less likely to collapse, which facilitates the improvement of the stability of the connector 3. At the same time, the structure of the first part 33 is relatively simple, which facilitates the improvement of the manufacturing efficiency of the connector 3. The end of the first plate portion 33a away from the second plate portion 33b is integrally connected to the second part 34. The second part 34 is a plate structure, which facilitates the processing of the connector 3 and makes it easier to make the structural strength of the first part 33 better than that of the second part 34.

[0068] like Figure 3As shown, in some embodiments, the vehicle headlight 100 is configured to satisfy condition A3, the mating parts 21 are multiple and the multiple mating parts 21 include a first mating part 21a and a second mating part 21b, the circuit board 20 has a first mating part 21a at one end in a first direction, the circuit board 20 has a second mating part 21b at both ends in a second direction, the inner wall surface of the housing 1 has a first support structure 11, the first support structure 11 abuts against the first mating part 21a on the side where the main body 30 is located, the inner wall surface of the housing 1 has a second support structure 12, the second support structure 12 supports the second mating part 21b on the side away from the main body 30.

[0069] For example, taking the thickness direction of the circuit board 20 as the vertical direction, the main body 30 is disposed on the upper side of the circuit board 20, the first support structure 11 abuts against the upper side of the first mating part 21a, and the second support structure 12 supports the lower side of the second mating part 21b.

[0070] As can be seen, the size of the circuit board 20 in the second direction is larger than that in the first direction. The first support structure 11 abuts against the first mating part 21a on the side where the main body 30 is located, so the first support structure 11 can support the thickness side of the main body 30. The second support structure 12 supports the second mating part 21b on the side away from the main body 30, so the second support structure 12 can support the thickness side of the main body 30. The first support structure 11 and the second support structure support the thickness sides of the main body 30 respectively. Moreover, since the circuit board 20 has the first mating part 21a at one end in the first direction and the circuit board 20 has the second mating parts 21b at both ends in the second direction, the first support structure 11 corresponding to the first mating part 21a and the second support structure 12 corresponding to the second mating part 21b can be distributed at intervals along the second direction, so that the circuit board 20 can get a better support effect at each position in the second direction, thereby reducing the possibility of the circuit board 20 shaking or collapsing locally, and facilitating the improvement of the stability of the light source assembly 2.

[0071] In some embodiments, there are multiple connectors 3, and the multiple connectors 3 are spaced apart along the second direction. After the multiple connectors 3 cooperate with the same circuit board 20, they can support the circuit board 20 to a certain extent, so as to further enhance the structural stability of the circuit board 20. The arrangement of the multiple connectors 3 is relatively matched with the size of the circuit board 20 in the second direction. So even if the size of the circuit board 20 in the second direction is large, the multiple connectors 3 can support the suspended part of the circuit board 20 except for the mating part 21, effectively reducing the possibility of the circuit board 20 shaking or partially collapsing, so that the light source assembly 2 can have a more stable light output effect, which is conducive to improving the stability of the vehicle lamp 100 operation.

[0072] like Figure 3As shown, in some embodiments, the vehicle lamp 100 is configured to also satisfy condition A1, where the first support structure 11 and the fixed end 30a are located on the same side of the circuit board 20 in a first direction, for example, the width direction of the circuit board 20. The first support structure 11 and the fixed end 30a are both located on the same side of the circuit board 20 in the width direction, which can make full use of the space of the circuit board 20 in the first direction without reserving installation space in multiple directions. This makes it easier for the first support structure 11 to affect the arrangement of various components (e.g., light source 23) on the circuit board 20, making the structure of each component in the vehicle lamp 100 more compact and facilitating the miniaturization design of the vehicle lamp 100.

[0073] It is understandable that when the headlight 100 is configured to satisfy conditions A1 and A3, if there are multiple connectors 3, the fixed ends 30a of the multiple connectors 3 and the first support structure 11 are all located on the same side of the circuit board 20 in the first direction.

[0074] like Figure 4 As shown, in some embodiments, the vehicle headlight 100 is configured to satisfy at least one of the following conditions:

[0075] In condition B1, the light source 23 is located on the side of the circuit board 20 away from the main body 30. The main body 30 covers the mating through hole 22 so that the light emitted by the light source 23 is not easy to leak out through the mating through hole 22, making the light path inside the headlight 100 clearer. That is, the light will not shine through the mating through hole 22 to the position of the headlight 100 that should not emit light, which is conducive to improving the light output effect of the headlight 100.

[0076] In condition B2, the light source 23 is located on the side of the circuit board 20 away from the main body 30. The housing 1 includes a lamp housing 13 and a lamp shade 14 arranged opposite to each other along a first direction. The lamp housing 13 and the lamp shade 14 cooperate to define the mounting cavity 10. The lamp housing 13 cooperates with the mating part 21 and is fixedly connected to the connector 3. A reflective structure 15 is integrally provided on the lamp housing 13. The reflective structure 15 is opposite to the light source 23 along the thickness direction of the circuit board 20 so as to reflect the light emitted by the light source 23 toward the lamp shade 14. The first direction is perpendicular to the thickness direction of the circuit board 20.

[0077] As can be seen, the lamp housing 13 is fitted with the mating part 21 of the circuit board 20, and the lamp housing 13 is fixedly connected to the connector 3. The circuit board 20 is fitted with the connector 3 so that the circuit board 20 can be fixed to the mounting cavity 10 through the connector 3 and the mating part 21, so that the setting position of the light source assembly 2 is more stable, which facilitates the improvement of the stability of the vehicle lamp 100 operation and simplifies the structure of the lamp cover 14.

[0078] In addition, the reflective structure 15 and the light source 23 are arranged opposite to each other along the thickness direction of the circuit board 20, so that the light path between the light source 23 and the emitting structure is shorter, making the light less susceptible to interference from other components. The light emitted by the light source 23 can change the light path through the reflective structure 15 and then be emitted through the lamp cover 14 to achieve good light output of the vehicle lamp 100, which helps to improve the stability of the vehicle lamp 100 operation.

[0079] The lamp housing 13 is integrally provided with a reflective structure 15, so the reflective structure 15 and the lamp housing 13 can be integrally formed, realizing the integration of the two. This allows the reflective structure 15 and the lamp housing 13 to be produced using a single mold, which helps to reduce the production cost of the vehicle lamp 100 and facilitates the mass production of the vehicle lamp 100. At the same time, the integrally formed lamp housing 13 and reflective structure 15 do not require an additional locking structure to fix the lamp housing 13 and reflective structure 15, which helps to reduce the assembly complexity of the vehicle lamp 100 and improve the assembly efficiency of the vehicle lamp 100.

[0080] In related technologies, due to the limited space inside the vehicle lamp, the light source component cannot be fixed to the lamp housing by fasteners along the thickness direction of the circuit board. It is necessary to fix the reflective structure to the light source component first, and then assemble the reflective structure and the light source component as a whole into the lamp housing. Then, the reflective structure is fixed to the lamp housing by fasteners along the first or second direction. This is not conducive to the integrated design of the reflective structure and the lamp housing. However, in this application, the light source component 2 can be fixed to the lamp housing 13 by the connector 3. It is not necessary to fix the light source component 2 to the lamp housing 13 by fasteners 5 along the thickness direction of the circuit board 20. This allows the reflective structure 15 and the lamp housing 13 to be integrated into the design, which reduces the assembly complexity of the vehicle lamp 100 and is conducive to the mass production of the vehicle lamp 100.

[0081] In other embodiments of this application, magnetic components may be provided on the light source assembly 2 and the lamp housing 13 respectively, so as to achieve the positioning and fixing of the light source assembly 2 by means of magnetic attraction; or, adhesive components may be used to fix the light source assembly 2 to the lamp housing 13.

[0082] like Figure 2 and Figure 3 As shown, in some embodiments, the vehicle lamp 100 includes multiple light source components 2, which are spaced apart along a second direction, and are respectively fixed to the lamp housing 13 by corresponding connectors 3. By using multiple light source components 2, the light emission range and light emission effect of the vehicle lamp 100 can be further increased. Of course, there can also be only one light source component 2.

[0083] The vehicle 200 according to the second aspect of the present invention includes the headlights 100 according to the first aspect of the present invention.
