[0002] In related technologies, screws are used to assemble and fix the lens unit and other components. When the screws are inserted into the curved area of ​​the lens unit, the lens unit will be subjected to oblique force. This may cause local skew due to uneven force, which will affect the light output effect. In addition, screwing the lens unit will make the installation process relatively complicated and time-consuming. In mass production, it will prolong the production cycle and affect the production efficiency of the vehicle lights. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a vehicle lamp and vehicle in which the lens unit is positioned and fitted with the housing assembly and / or light source assembly via a first positioning structure. Simultaneously, the lens unit is clamped between the first and second housing walls, thus completing the assembly and fixation of the lens unit.

At the same time, the lens unit is clamped between the first housing wall and the second housing wall. For example, at least a portion of the lens unit abuts against the first housing wall and the second housing wall respectively, so that the lens unit is not easy to move along the first direction, making the setting position of the lens unit more stable and less likely to affect the light output effect. Moreover, the assembly and fixing of the lens unit does not require the use of screws, which facilitates the assembly efficiency of the vehicle lamp and facilitates the mass production of the vehicle lamp.

[0006] In some embodiments, the first positioning structure comprises multiple positioning protrusions, including a first positioning protrusion and a second positioning protrusion, and multiple positioning holes, including a first positioning hole and a second positioning hole.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[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 1-9 As shown, the vehicle headlight 100 includes: a housing assembly 1, a light source assembly 2, and a lens unit 3. The housing assembly 1 has a mounting cavity 10. The housing assembly 1 has a first shell wall 11 and a second shell wall 12 arranged opposite to each other along a first direction and forming the mounting cavity 10. The light source assembly 2 is fixed in the mounting cavity 10, and the lens unit 3 is disposed in the mounting cavity 10. At least one of the housing assembly 1 and the light source assembly 2 is positioned and engaged with the lens unit 3 by at least one first positioning structure 4 to restrict the movement of the lens unit 3 in a preset plane. The first positioning structure 4 includes a positioning protrusion 40 and a positioning hole 41 for positioning and engagement. The first direction is perpendicular to the preset plane, and the lens unit 3 is sandwiched between the first shell wall 11 and the second shell wall 12 to restrict the movement of the lens unit 3 along the first direction.

[0038] As can be seen, the first shell wall 11 and the second shell wall 12 are arranged opposite to each other along the first direction, and both the first shell wall 11 and the second shell wall 12 participate in forming the mounting cavity 10. The light source assembly 2 and the lens unit 3 are both located in the mounting cavity 10, so that the light source assembly 2 and the lens unit 3 are not easily affected by the external environment, which facilitates the improvement of the stability of the vehicle lamp 100 operation. For example, the light source assembly 2 includes a circuit board and an LED light source. By placing the light source assembly 2 in the mounting cavity 10, the circuit board and the LED light source are not easily contaminated by external impurities, so that the light source assembly 2 can have a stable light output effect.

[0039] Furthermore, at least one of the housing assembly 1 and the light source assembly 2 is positioned and engaged with the lens unit 3 through at least one first positioning structure 4 to restrict the movement of the lens unit 3 within a preset plane. For example, the first positioning structure 4 can be used to restrict the movement and rotation of the lens unit 3 relative to the housing assembly 1 and the light source assembly 2 within the preset plane. Simultaneously, the lens unit 3 is sandwiched between the first housing wall 11 and the second housing wall 12, so the first housing wall 11 and the second housing wall 12 respectively abut against the opposite sides of the lens unit 3 to restrict the movement of the lens unit 3 along the first direction. For example, it restricts the movement of the lens unit 3 towards or away from the first housing wall 11 and / or the second housing wall 12 along the first direction, so that the positioning protrusion 40 and the positioning hole 41 are not easy to detach, making the setting position of the lens unit 3 more stable and the lens unit 3 less prone to risks such as skewness. This allows the vehicle lamp 100 to have a good light output effect, and the assembly and fixing of the lens unit 3 does not require the use of screws, which facilitates the improvement of the assembly efficiency of the vehicle lamp 100 and is conducive to the mass production of the vehicle lamp 100.

[0040] The first positioning structure 4 includes a positioning protrusion 40 and a positioning hole 41. By aligning and inserting the positioning protrusion 40 into the positioning hole 41, at least one of the housing assembly 1 and the light source assembly 2 can be assembled with the lens unit 3. The assembly process is relatively simple and facilitates the improvement of the assembly efficiency of the vehicle lamp 100.

[0041] For example, if the housing assembly 1 and the lens unit 3 are positioned and engaged by at least one first positioning structure 4, it includes: the first housing wall 11 and the lens unit 3 being positioned and engaged by at least one first positioning structure 4, and / or, the second housing wall 12 and the lens unit 3 being positioned and engaged by at least one first positioning structure 4.

[0042] In related technologies, screws are used to assemble and fix the lens unit and other components (such as light source components and housing components). When the screws are inserted into the curved area of ​​the lens unit, the lens unit will be subjected to oblique force. The screws will exert a squeezing force on the lens unit, which may cause local skew due to uneven force, affecting the light output effect. Moreover, screwing the lens unit will make the installation process relatively complicated and time-consuming. In mass production, it will prolong the production cycle and affect the production efficiency of the vehicle lights.

[0043] According to the embodiment of the present invention, at least one of the housing assembly 1 and the light source assembly 2 is positioned and engaged with the lens unit 3 through at least one first positioning structure 4, so that the lens unit 3 is not easily moved or rotated within a preset plane. At the same time, the lens unit 3 is clamped between the first housing wall 11 and the second housing wall 12, so that the lens unit 3 is not easily moved along the first direction, making the setting position of the lens unit 3 more stable and less likely to affect the light output effect. Moreover, the assembly and fixing of the lens unit 3 does not require the use of screws. The first positioning structure 4 only restricts the movement of the lens unit 3 within the preset plane, without applying a squeezing force to the lens unit 3 in the first direction. Even if the first positioning structure 4 is located in the curved area of ​​the lens unit 3, since the lens unit 4 is clamped between the first housing wall 11 and the second housing wall 12, the lens unit 4 is not prone to deflection risk, so that the vehicle lamp 100 can have a better light output effect, and it is also convenient to realize the mass production of the vehicle lamp 100 and to improve the service life of the lens unit 3.

[0044] It is understood that at least one of the housing assembly 1 and the light source assembly 2 is positioned and engaged with the lens unit 3 through at least one first positioning structure 4 to restrict the movement of the lens unit 3 within a preset plane. This can include the following examples: Example 1: The housing assembly 1 and the lens unit 3 are positioned and engaged through one first positioning structure 4 to restrict the movement of the lens unit 3 within a preset plane; Example 2: The light source assembly 2 and the lens unit 3 are positioned and engaged through one first positioning structure 4 to restrict the movement of the lens unit 3 within a preset plane; Example 3: The housing assembly 1 and the lens unit 3 are positioned and engaged through one first positioning structure 4, and the light source assembly 2 and the lens unit 3 are also positioned and engaged through one first positioning structure 4 to restrict the movement of the lens unit 3 within a preset plane; Example 4: The housing assembly 1 and the lens unit 3 are positioned and engaged through multiple first positioning structures 4 to restrict the movement of the lens unit 3 within a preset plane. Movement within a preset plane; Example 5: The light source assembly 2 and the lens unit 3 are positioned and engaged by multiple first positioning structures 4 to restrict the movement of the lens unit 3 within a preset plane; Example 6: The housing assembly 1 and the lens unit 3 are positioned and engaged by one first positioning structure 4, and the light source assembly 2 and the lens unit 3 are positioned and engaged by multiple first positioning structures 4 to restrict the movement of the lens unit 3 within a preset plane; Example 7: The housing assembly 1 and the lens unit 3 are positioned and engaged by multiple first positioning structures 4, and the light source assembly 2 and the lens unit 3 are positioned and engaged by one first positioning structure 4 to restrict the movement of the lens unit 3 within a preset plane; Example 8: The housing assembly 1 and the lens unit 3 are positioned and engaged by multiple first positioning structures 4, and the light source assembly 2 and the lens unit 3 are positioned and engaged by multiple first positioning structures 4 to restrict the movement of the lens unit 3 within a preset plane.

[0045] It is understood that when at least one of the housing assembly 1 and the light source assembly 2 is positioned and engaged with the lens unit 3 through a first positioning structure 4, the first positioning structure 4 can restrict the movement of the lens unit 3 in a preset plane through its own structure. For example, the cross-sectional shape of the positioning hole 41 and the positioning protrusion 40 are both non-circular, so that the lens unit 3 is not easy to move or rotate in the preset plane. When at least one of the housing assembly 1 and the light source assembly 2 is positioned and engaged with the lens unit 3 through multiple first positioning structures 4, the first positioning structure 4 can restrict the movement of the lens unit 3 in the preset plane through the combination of its own structure, number and setting position. At this time, the cross-sectional shape of the positioning protrusion 40 is not specifically restricted.

[0046] Therefore, this application does not limit the location or number of the first positioning structure 4, so that the setting of the first positioning structure 4 can be more flexible, making it easier to adapt to different installation environments and improving the flexibility of the vehicle light 100.

[0047] like Figures 4-6 As shown, in some embodiments, the lens unit 3 is a one-piece molded part, and the lens unit 3 includes a bracket 33 and a lens 34. The lens 34 is an optical element used to process the light emitted by the light source assembly 2. The bracket 33 is fixed to the light source assembly 2 and / or the housing assembly 1 through a first positioning structure 4. In related technologies, the lens unit only includes the lens, and screws are used to pass through the middle of the lens, which may scratch the lens and affect the light output effect of the vehicle lamp. However, in this application, the light source assembly 2 and / or the housing assembly 1 are fixed to the bracket 33 through the first positioning structure 4 to achieve indirect fixation of the lens 34, which is less likely to damage the lens 34, facilitates the improvement of the service life of the lens 34, and improves the light output stability of the vehicle lamp 100. The lens 34 can be an inner lens.

[0048] like Figure 2 and Figures 7-9 As shown, in some embodiments, there are multiple first positioning structures 4, including multiple positioning protrusions 40 including a first positioning protrusion 40a and a second positioning protrusion 40b, and multiple positioning holes 41 including a first positioning hole 41a and a second positioning hole 41b. The first positioning protrusion 40a and the first positioning hole 41a are positioned and engaged in a second direction, and the first positioning protrusion 40a and the first positioning hole 41a are clearance-fitted in a third direction. The second positioning protrusion 40b and the second positioning hole 41b are positioned and engaged in a third direction, and the second positioning protrusion 40b and the second positioning hole 41b are clearance-fitted in a second direction. Both the second direction and the third direction are parallel to a preset plane.

[0049] For example, the first positioning hole 41a extends into an elongated hole along a third direction, so that after the first positioning protrusion 40a is engaged with the first positioning hole 41a, the first positioning protrusion 40a can move relative to the first positioning hole 41a along the third direction, but cannot move along the second direction; the second positioning hole 41b extends into an elongated hole along the second direction, so that after the second positioning protrusion 40b is engaged with the second positioning hole 41b, the second positioning protrusion 40b can move relative to the second positioning hole 41b along the second direction, but cannot move along the third direction.

[0050] It is evident that when the first positioning protrusion 40a and the first positioning hole 41a are misaligned due to manufacturing errors and are separated by a certain distance in the second direction, the second positioning protrusion 40b can be moved along the second direction in the second positioning hole 41b so that the first positioning protrusion 40a can engage with the first positioning hole 41a. Similarly, when the second positioning protrusion 40b and the second positioning hole 41b are misaligned due to a certain distance in the third direction, the first positioning protrusion 40a can be moved along the third direction in the first positioning hole 41a so that the second positioning protrusion 40b can engage with the second positioning hole 41b. This reduces the difficulty of aligning the positioning protrusion 40a and the positioning hole 41b, improving the assembly efficiency of the headlight 100. Furthermore, when both the first positioning protrusion 40a and the second positioning protrusion 40b are engaged with the first positioning hole 41a and the second positioning hole 41b respectively, the movement of the lens unit 3 within the preset plane is effectively restricted, making the position of the lens unit 3 more stable and improving the stability of the headlight 100.

[0051] like Figure 3 and Figures 7-9As shown, in some embodiments, one of the first positioning holes 41a and the second positioning holes 41b is multiple, and the other of the first positioning holes 41a and the second positioning holes 41b is provided between adjacent two. For example, there are multiple first positioning holes 41a and a second positioning hole 41b is provided between adjacent two first positioning holes 41a, or there are multiple second positioning holes 41b and a first positioning hole 41a is provided between adjacent two second positioning holes 41b, so that the arrangement of the first positioning holes 41a and the second positioning holes 41b is more regular, which facilitates the improvement of the processing efficiency of the positioning holes 41; and / or, the first positioning hole 41a and the second positioning hole 41b are arranged in a more regular manner. If at least one of the positioning holes 41b penetrates the outer peripheral wall of the light source assembly 2, then at least one of the first positioning holes 41a and the second positioning holes 41b is located at the edge of the light source assembly 2. At the same time, at least one of the first positioning protrusions 40a and the second positioning protrusions 40b is located at the edge of the lens unit 3, so that the first positioning structure 4 can better limit the entire lens unit 3, is not easily interfered with by other components, and is easier to resist external vibration, impact and other interference factors, which is conducive to improving the stability of the vehicle lamp 100 operation. Moreover, the size of the corresponding positioning protrusion 40 is not easily limited by the positioning hole 41.

[0052] like Figures 2-4 As shown, in some embodiments, the light source assembly 2 is spaced apart from the first shell wall 11, and the light source assembly 2 is positioned and engaged with the second shell wall 12 by at least one second positioning structure 5. A portion of the lens unit 3 is located between the light source assembly 2 and the first shell wall 11, and the aforementioned portion of the lens unit 3 is positioned and engaged with the light source assembly 2 by at least the first positioning structure 4.

[0053] As can be seen, the light source assembly 2 and the first housing wall 11 are spaced apart, providing a larger operating space for the lens unit 3 to be assembled into the light source assembly 2, so that the lens unit 3 is less likely to interfere with the first housing wall 11 after being assembled into the light source assembly 2, which facilitates the improvement of the assembly efficiency of the vehicle lamp 100; the light source assembly 2 and the second housing wall 12 are positioned and cooperated by at least one second positioning structure 5 so as to achieve reliable installation of the light source assembly 2, and the lens unit 3 is positioned and cooperated with the light source assembly 2 at least, so that the lens unit 3 can at least indirectly limit the housing assembly 1 through the light source assembly 2, which facilitates the stability of the entire vehicle lamp 100 structure.

[0054] Furthermore, the lens unit 3 is positioned and cooperates with the light source assembly 2 at least through the first positioning structure 4, so that the lens unit 3 and the light source assembly 2 are not prone to relative movement within a preset plane. Moreover, the lens unit 3 is sandwiched between the first shell wall 11 and the second shell wall 12, so that at least a part of the light source assembly 2 is sandwiched between the second shell wall 12 and the lens unit 3, thereby restricting the movement of the light source assembly 2 along the first direction, making it difficult for the light source assembly 2 and the lens unit 3 to separate along the first direction, making the relative position of the lens unit 3 and the light source assembly 2 more stable, so that the light emitted by the light source assembly 2 can be effectively guided by the lens unit 3, which helps to improve the stability of the vehicle lamp 100 operation.

[0055] like Figures 2-4 As shown, in some embodiments, there are multiple second positioning structures 5. One of the second positioning structures 5 includes a third positioning protrusion 50 and a third positioning hole 51. One of the remaining second positioning structures 5 includes a fourth positioning protrusion 52 and a fourth positioning hole 53. The third positioning protrusion 50 and the third positioning hole 51 are positioned and engaged in a second direction, and the third positioning protrusion 50 and the third positioning hole 51 are clearance-fitted in a third direction. The fourth positioning protrusion 52 and the fourth positioning hole 53 are positioned and engaged in a third direction, and the fourth positioning protrusion 52 and the fourth positioning hole 53 are clearance-fitted in a second direction. Both the second direction and the third direction are parallel to a preset plane. And / or, a first clearance portion 30 is formed on the lens unit 3 to avoid the second positioning structure 5.

[0056] It is evident that when the third positioning protrusion 50 and the third positioning hole 51 are misaligned due to manufacturing errors and are separated by a certain distance in the second direction, the fourth positioning protrusion 52 can be moved along the second direction in the fourth positioning hole 53 so that the third positioning protrusion 50 can fit into the third positioning hole 51. Simultaneously, when the fourth positioning protrusion 52 and the fourth positioning hole 53 are misaligned due to a certain distance in the third direction, the third positioning protrusion 50 can be moved along the third direction in the third positioning hole 51 so that the fourth positioning protrusion 52 can fit into the fourth positioning hole 53. This facilitates reducing the difficulty of fitting the second positioning structure 5, improves the assembly efficiency of the headlight 100, and when the third positioning protrusion 50 and the fourth positioning hole 53 are misaligned, the third positioning protrusion 50 can be moved along the third direction in the third positioning hole 51 so that the fourth positioning protrusion 52 can fit into the fourth positioning hole 53. This reduces the difficulty of fitting the second positioning structure 5, improves the assembly efficiency of the headlight 100, and also reduces the difficulty of fitting the second positioning structure 5. After the protrusions 52 are respectively engaged with the third positioning hole 51 and the fourth positioning hole 53, they can effectively restrict the relative movement between the light source assembly 2 and the lens unit 3, so as to make the relative position of the light source assembly 2 and the lens unit 3 more stable and improve the stability of the vehicle lamp 100; and / or, the lens unit 3 is provided with a first clearance part 30 to avoid the engagement of the second positioning structure 5. For example, after the light source assembly 2 is engaged with the second housing wall 12, the second positioning structure 5 can protrude from the side of the light source assembly 2 facing the lens unit 2. By setting the first clearance part 30, the second positioning structure 5 is less likely to affect the engagement of the lens unit 3 with the light source assembly 2 through the first positioning structure 4, which facilitates the assembly feasibility of the vehicle lamp 100.

[0057] like Figure 2 and Figures 7-9 As shown, in some embodiments, a positioning protrusion 40 is formed on the lens unit 3, a positioning hole 41 is formed on the light source assembly 2, and a second clearance portion 12a is formed on the second shell wall 12 to avoid the positioning protrusion 40. When the lens unit 3 is fitted to the light source assembly 2, the positioning protrusion 40 fits into the positioning hole 41 and extends out of the positioning hole 41. The positioning protrusion 40 extends to the side of the positioning hole 41 facing the second shell wall 12. By providing the second clearance portion 12a, the second shell wall 12 does not interfere with the first positioning structure 4, and the second shell wall 12 is less likely to affect the positioning. The cooperation between the protrusion 40 and the positioning hole 41 reduces the assembly difficulty of the light source assembly 2 and the lens unit 3, which is conducive to improving the assembly feasibility of the vehicle lamp 100. At the same time, when the positioning protrusion 40 needs to move in a certain direction within the positioning hole 41 (such as the second direction and the third direction mentioned above), the second clearance part 12a can also avoid the movement of the positioning protrusion 40 within the positioning hole 41, so that the positioning protrusion 40 is less likely to interfere with the second shell wall 12, which facilitates the assembly efficiency of the vehicle lamp 100 and is conducive to the mass production of the vehicle lamp 100.

[0058] In other embodiments of this application, a positioning protrusion 40 is formed on the lens unit 3, and positioning holes 41 are formed on the light source assembly 2 and the second shell wall 12, respectively. The positioning holes 41 on the light source assembly 2 and the corresponding positioning holes 41 on the second shell wall 12 are opposite to each other and are positioned and engaged with the same positioning protrusion 40. That is, by the same positioning protrusion 40 passing through the positioning holes 41 on the light source assembly 2 and the corresponding positioning holes 41 on the second shell wall 12, the relative movement of the light source assembly 2, the lens unit 3 and the second shell wall 12 in the preset plane can be restricted, which is beneficial to enhance the cooperation strength of the first positioning structure 4, so that the relative positions of the light source assembly 2, the lens unit 3 and the second shell wall 12 are more stable, and the stability of the vehicle lamp 100 operation can be improved.

[0059] Of course, in some embodiments, the positioning protrusion 40 is formed on the lens unit 3, the second shell wall 12 is formed with a positioning hole 41, the light source assembly 2 is formed with a clearance through hole, the positioning protrusion 40 passes through the clearance through hole and is positioned and matched with the positioning hole 41. In this case, the lens unit 3 can be positioned and matched with the second shell wall 12 through the first positioning structure 4, while the lens unit 3 is not positioned and matched with the light source assembly 2.

[0060] like Figure 2 , Figure 6 and Figure 7As shown, in some embodiments, the lens unit 3 has a plurality of spaced-apart first abutment portions 31 and a plurality of spaced-apart second abutment portions 32. Each first abutment portion 31 abuts against a first abutment protrusion 11a on the first shell wall 11, and each second abutment portion 32 abuts against a second abutment protrusion 12b on the second shell wall 12. That is, the lens unit 3 is abutted against and engaged with the first shell wall 11 by a plurality of first abutment portions 31, and the lens unit 3 is abutted against and engaged with the second shell wall 12 by a plurality of second abutment portions 32, so that the lens unit 3 can be supported and fixed at multiple points, making the setting position of the lens unit 3 more stable, and the lens unit 3 is less likely to move or shake along the first direction, which facilitates the improvement of the stability of the vehicle lamp 100 operation.

[0061] Lens unit 3 is configured to satisfy at least one of the following conditions A1 to A3:

[0062] In condition A1, the number of first stop portions 31 is at least three. On the preset plane, the orthographic projections of the multiple first stop portions 31 are not collinear, so that the multiple first stop portions 31 can be staggered on the lens unit 3, so that the multiple first stop portions 31 can abut against the first shell wall 11 from different positions, so that the setting position of the lens unit 3 is more stable. At the same time, the staggered arrangement of the multiple first stop portions 31 makes the lens unit 3 less likely to be subjected to excessive local pressure, so that the lens unit 3 is less likely to be damaged due to excessive pressure, and thus improves the service life of the lens unit 3.

[0063] In condition A2, the number of second stop portions 32 is at least three. On the preset plane, the orthographic projections of the multiple second stop portions 32 are not collinear, so that the multiple second stop portions 32 can be staggered on the lens unit 3, so that the multiple second stop portions 32 can abut against the second shell wall 12 from different positions, making the setting position of the lens unit 3 more stable. At the same time, the staggered arrangement of the multiple second stop portions 32 makes the lens unit 3 less likely to be subjected to excessive local pressure, so that the lens unit 3 is less likely to be damaged due to excessive pressure, thus improving the service life of the lens unit 3.

[0064] In condition A3, on the preset plane, the orthographic projection of each first stop part 31 and the orthographic projection of any second stop part 32 are spaced apart, that is, multiple first stop parts 31 and multiple second stop parts 32 are staggered and not vertically opposite each other, so that the lens unit 3 can be supported and fixed in different positions, making the setting position of the lens unit 3 more stable, and the lens unit 3 is not easy to move or shake along the first direction, which helps to improve the stability of the vehicle lamp 100 operation.

[0065] like Figures 1-9As shown, in some embodiments, the housing assembly 1 includes a housing 13 and a heat sink 14, the heat sink 14 and the housing 13 cooperating to jointly define a mounting cavity 10, a first housing wall 11 formed on the housing 13, a second housing wall 12 formed on the heat sink 14, and the second housing wall 12 having a first portion and a second portion connected together, the first portion being thermally engaged with the light source assembly 2, and the second portion being abutted against the lens unit 3.

[0066] As can be seen, the first part is thermally conductively coupled with the light source assembly 2 to maintain the temperature of the light source assembly 2 at a relatively stable level during operation, thereby enabling the light source assembly 2 to have a relatively stable light output effect and improving the operational stability of the vehicle lamp 100. Furthermore, the second part abuts against the lens unit 3, with the lens unit 3 abutting between the second part and the first housing wall 11, and the light source assembly 2 thermally conductively coupled to the first part. By spacing the positions of the lens unit 3 and the second part abutting against the light source assembly 2, the light source assembly 2 is less susceptible to excessive compressive force, which helps to extend its service life and improve the operational stability of the vehicle lamp 100.

[0067] For example, such as Figure 2 and Figure 6 As shown, the first part and the second part can be arranged sequentially along the second direction. The first part is located on one side of the light source assembly 2 in the first direction, and the second part is offset from the light source assembly 2 in the second direction. The second part is arranged opposite to a part of the lens unit 2 in the first direction.

[0068] like Figures 2-4 As shown, in some embodiments, the heat sink 14 defines a mounting space 14a corresponding to a portion of the mounting cavity 10. The mounting space 14a has a first opening 14b and a second opening 14c located on different sides. The first opening 14b is configured to allow the light source assembly 2 and the lens unit 3 to pass through and be accommodated in the mounting space 14a. The first shell wall 11 is detachably covered by the first opening 14b.

[0069] As can be seen, the first opening 14b is formed on one side of the installation space 14a in the first direction. For example, the central axis of the first opening 14b extends along the first direction. The first shell wall 11 is detachably covered by the first opening 14b. The first opening 14b provides a larger operating space for the assembly of the light source assembly 2 and the lens unit 3. The operator can first assemble the light source assembly 2 and the lens unit 3 into a whole in the external environment, and then assemble the light source assembly 2 and the lens unit 3 into the installation space 14a through the first opening 14b. Alternatively, the operator can assemble the light source assembly 2 and the lens unit 3 into the installation space 14a in sequence through the first opening 14b, and then cover the first opening 14b with the first shell wall 11, so that the light source assembly 2 and the lens unit 3 are both located in the relatively closed installation cavity 10. Therefore, the assembly of the vehicle lamp 100 can be completed through the above assembly process, which can improve the assembly efficiency of the vehicle lamp 100, speed up the production cycle, and facilitate the mass production of the vehicle lamp 100. At the same time, when it is necessary to maintain or replace the light source assembly 2 and the lens unit 3, the first shell wall 11 can be removed to expose the first opening 14b, so that the staff can more easily access the light source assembly 2 and the lens unit 3, which can reduce the maintenance difficulty and maintenance cost of the vehicle lamp 100.

[0070] Optionally, the first shell wall 11 is detachably covered by the first opening 14b by fasteners (e.g., screws). The fastening force of the fasteners can make the lens unit 3 more stably clamped between the first shell wall 11 and the second shell wall 12, so that the setting position of the lens unit 3 is more stable. At the same time, the fasteners make the installation and disassembly of the first shell 13 and the first opening 14b more convenient, which facilitates subsequent maintenance and repair, and makes the overall structure more compact and saves space.

[0071] The housing 13 also includes a lampshade 15, which is separately disposed from the first housing wall 11. The lampshade 15 can be inserted into the radiator 14 along a first direction so that the lampshade 15 can cover the second opening 14c. The lampshade 15 is positioned between the radiator 14 and the first housing wall 11. For example, the radiator 14 has a positioning opening and the lampshade 15 has a positioning post. By inserting the positioning post into the positioning opening along the first direction so that the lampshade 15 covers the second opening 14c, the assembly of the lampshade 15 and the radiator 14 can be completed. Then, the first housing wall 11 is assembled into the first opening 14b so that the lampshade 15 is sandwiched between the radiator 14 and the first housing wall 11, making the setting position of the lampshade 15 more stable, so that light can pass through the lampshade 15 smoothly and improve the stability of the vehicle lamp 100 operation.

[0072] 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.

[0073] The vehicle 200 according to the present utility model adopts the above-mentioned headlight 100, which facilitates the improvement of the assembly efficiency of the vehicle 200.

[0074] It is understood that the specific type of vehicle 200 referred to in this application embodiment is not limited. For example, vehicle 200 can be a gasoline vehicle, a natural gas vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, range-extended electric vehicles, solar electric vehicles, gas fuel vehicles (such as hydrogen engine vehicles), or biofuel vehicles (such as vehicles powered by ethanol, biodiesel, etc.). In addition, when the headlight 100 is applied to vehicle 200, the headlight 100 can be a high beam, low beam, etc., in the headlights, but is not limited to these.

[0075] Other configurations and operations of the vehicle 200 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0076] Please refer to this again. Figures 1-9 The present application describes a specific embodiment of a vehicle lamp 100, which includes a housing assembly 1, a light source assembly 2, and a lens unit 3.

[0077] The housing assembly 1 has a mounting cavity 10. The housing assembly 1 includes a housing 13 and a heat sink 14. The heat sink 14 and the housing 13 cooperate to jointly define the mounting cavity 10. A first housing wall 11 is formed on the housing 13, and a second housing wall 12 is formed on the heat sink 14. The first housing wall 11 and the second housing wall 12 are arranged opposite to each other along a first direction and participate in forming the mounting cavity 10. The second housing wall 12 has a first part and a second part connected together. The first part is thermally conductively engaged with the light source assembly 2, and the second part abuts against the lens unit 3. The portion of the heat sink 14 corresponding to the mounting cavity 10 is also specified. An installation space 14a is defined, which has a first opening 14b and a second opening 14c located on different sides. The first opening 14b is configured to allow the light source assembly 2 and the lens unit 3 to pass through and be accommodated in the installation space 14a. The first housing wall 11 is detachably covered by the first opening 14b. The housing 13 also includes a lampshade 15, which is covered by the second opening 14c and is separate from the first housing wall 11. The lampshade 15 can be inserted into the heat sink 14 along a first direction, and the lampshade 15 is positioned between the heat sink 14 and the first housing wall 11.

[0078] The light source assembly 2 is spaced apart from the first shell wall 11, and the light source assembly 2 and the second shell wall 12 are positioned and engaged by multiple second positioning structures 5. There are multiple second positioning structures 5, one of which includes a third positioning protrusion 50 and a third positioning hole 51. One of the remaining second positioning structures 5 includes a fourth positioning protrusion 52 and a fourth positioning hole 53. The third positioning protrusion 50 and the third positioning hole 51 are positioned and engaged in the second direction, and the third positioning protrusion 50 and the third positioning hole 51 are in a clearance engagement in the third direction. The fourth positioning protrusion 52 and the fourth positioning hole 53 are positioned and engaged in the third direction, and the fourth positioning protrusion 52 and the fourth positioning hole 53 are in a clearance engagement in the second direction. The second direction and the third direction are both parallel to the preset plane, and the first direction is perpendicular to the preset plane.

[0079] The lens unit 3 is disposed in the mounting cavity 10. A first clearance portion 30 is formed on the lens unit 3 to avoid the second positioning structure 5. The light source assembly 2 and the lens unit 3 are positioned and engaged by multiple first positioning structures 4 to restrict the movement of the lens unit 3 in a preset plane. The first positioning structure 4 includes positioning protrusions 40 and positioning holes 41 for positioning and engagement. The multiple positioning protrusions 40 include first positioning protrusions 40a and second positioning protrusions 40b. The multiple positioning holes 41 include first positioning holes 41a and second positioning holes 41b. The first positioning protrusions 40a and the first positioning holes 41a are positioned and engaged in a second direction, and the first positioning protrusions 40a and the first positioning holes 41a are clearance engaged in a third direction. The second positioning protrusions 40b and the second positioning holes 41b are positioned and engaged in a third direction, and the second positioning protrusions 40b and the second positioning holes 41b are clearance engaged in a second direction. There are multiple first positioning holes 41a, and a second positioning hole 41b is provided between two adjacent first positioning holes 41a. The first positioning holes 41a penetrate the outer peripheral wall of the light source assembly 2.

[0080] The lens unit 3 has three spaced-apart first stop portions 31 and three spaced-apart second stop portions 32. Each first stop portion 31 abuts against a first stop protrusion 11a on the first shell wall 11, and each second stop portion 32 abuts against a second stop protrusion 12b on the second shell wall 12, so as to restrict the movement of the lens unit 3 along the first direction. On a preset plane, the orthographic projections of the plurality of first stop portions 31 are not collinear, the orthographic projections of the plurality of second stop portions 32 are not collinear, and the orthographic projections of each first stop portion 31 and any second stop portion 32 are spaced apart.

[0081] A positioning protrusion 40 is formed on the lens unit 3, a positioning hole 41 is formed on the light source assembly 2, and a second clearance portion 12a is formed on the second shell wall 12 to avoid the positioning protrusion 40.

[0082] The assembly process of the vehicle light 100 in this application embodiment is explained with the first direction as the up and down direction.

[0083] The first direction is vertical, so the preset plane is horizontal. The first opening 14b is located at the top of the installation space 14a, and the second shell wall 12 is the bottom wall of the installation space 14a. The operator can first assemble the light source assembly 2 and the lens unit 3 into the heat sink 14 through the first opening 14b. That is, the operator can first assemble the light source assembly 2 into the heat sink 14 through the second positioning structure 5 to restrict the movement of the light source assembly 2 on the horizontal plane, and then assemble the lens unit 3 into the light source assembly 2 through the first positioning structure 4 to restrict the movement of the lens unit 3 within the preset plane. At this time, the light source assembly 2 and the lens unit 3 are at least partially in contact. Then, the lampshade 15 is inserted into the heat sink 14 in the vertical direction. The lampshade 15 covers the second opening 14c, and then the first housing wall 11 is placed over the first opening 14b along the first direction, so that the lens unit 3 can be sandwiched between the radiator 14 and the housing 13 (i.e., the lens unit 3 is sandwiched between the first housing wall 11 and the second housing wall 12). The light source assembly 2 is sandwiched between the lens unit 3 and the radiator 14, and the lampshade 15 is sandwiched between the radiator 14 and the first housing wall 11. Then the housing 13 is locked to the radiator 14, so that the positions of the lens unit 3, the light source assembly 2 and the lampshade 15 are more stable. The light emitted by the light source assembly 2 is corrected by the lens unit 3 and then emitted through the lampshade 15, so that the vehicle lamp 100 can have a good light emission effect.

[0084] As can be seen, the assembly process of the above-mentioned vehicle light 100 is relatively simple. The assembly and positioning of the lens unit 3 does not require the use of screws, which reduces the probability of damage to the lens unit 3 during the assembly process, reduces the difficulty of assembly, speeds up the production cycle, and facilitates the mass production of the vehicle light 100.
