[0002] Lenses are optical parts that are generally made of plastic injection molding or glass compression molding. In automotive headlights, lenses control light distribution and imaging through refraction. They are the most basic optical components of the optical module. At the same time, because they are located at the front end of the optical module, they are also important appearance parts. Lenses are usually installed on lens brackets to facilitate reliable fixing of the lens on the reflector or radiator.

[0003] At present, the methods of fixing the lens and the lens holder include buckles, spring clips, laser welding, two-color injection molding, insert injection molding, glue, screws, etc. Among them, the traditional buckle structure has the lens clipped into the lens holder from front to back, from back to front, and is fastened by a third part, a snap ring. However, these fixing methods all have certain defects. For example, if the lens is clipped in from front to back, the hollow parts around the conventional buckle feet will cause light leakage, and the installation structure is obvious, affecting the aesthetics, and additional parts such as decorative rings or brim need to be installed to cover the installation structure; and the snap ring clip method will increase the number of snap ring parts, and there will be an additional installation process on the production line, resulting in an increase in production costs.

[0026] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] Example 1

[0028] The present embodiment provides a lens assembly, which includes: a lens holder 100 and a lens 200, wherein the lens holder 100 is provided with a light outlet 101 for configuring the lens 200, the lens holder 100 has a first clamping edge 3011 and a second clamping edge 3012 arranged at the edge of the light outlet 101, the outer surface of the lens holder 100 is a continuous surface, the lens holder 100 and the first clamping edge 3011 and the second clamping edge 3012 are formed as a whole, the edges of the lens 200 are respectively clamped with the first clamping edge 3011 and the second clamping edge 3012, and the first clamping edge 3011 and the second clamping edge 3012 respectively cover the edges of the lens 200.

[0029] Please refer to Figure 1As shown, in this embodiment, the lens holder 100 is arranged on the light exit side of the light source, and the upper edge and the lower edge of the light exit 101 of the lens holder 100 are folded toward the inside of the light exit 101 to form a first clamping edge 3011 and a second clamping edge 3012. When the lens 200 is covered at the light exit 101, the edge of the lens 200 is clamped with the first clamping edge 3011 and the second clamping edge 3012. The upper and lower edges at the light exit 101 of the lens holder 100 are folded inward to form a strip-shaped first clamping edge 3011 and a second clamping edge 3012 to form a buckle structure, and the outer surface of the lens holder 100 is a continuous surface, and the buckle structure and the lens holder 100 form a whole. And when the lens 200 is clamped with the lens holder 100, the first clamping edge 3011 and the second clamping edge 3012 respectively cover the two opposite edges of the lens 200. When the internal light source passes through the lens 200, since the outer surface of the lens holder 100 is a continuous surface without a hollow structure or a groove, and the edge of the lens 200 is covered by the first clamping edge 3011 and the second clamping edge 3012, there will be no light leakage, ensuring that the light emitted by the light source is emitted through the lens 200. The buckle structure formed by the first clamping edge 3011 and the second clamping edge 3012 has the same function as the existing lens buckle, and the lens 200 is also very convenient to disassemble and assemble, and there is no need to cover the decorative ring and other parts of the existing lens buckle, thereby ensuring the aesthetics of the lens 200 and the lens holder 100 without increasing the production cost, and having high practicality.

[0030] Optionally, in some implementations of the present embodiment, a plurality of mounting pins 201 are disposed on the edge of the lens 200 , and the mounting pins 201 are engaged with the first engaging edge 3011 and the second engaging edge 3012 .

[0031] Please refer to Figure 2As shown, the upper edge and the lower edge of the lens 200 are respectively clamped with the first clamping edge 3011 and the second clamping edge 3012. The upper and lower edges of the lens 200 are provided with mounting pins 201, and the mounting pins 201 are clamped with the first clamping edge 3011 and the second clamping edge 3012. After the lens 200 and the lens holder 100 are assembled, the side of the mounting pin 201 close to the light-emitting surface of the lens 200 abuts against the first clamping edge 3011 and the second clamping edge 3012, and the mounting pin 201 is covered by the first clamping edge 3011 and the second clamping edge 3012. On the one hand, the mounting pin 201 is tightly engaged with the first clamping edge 3011 and the second clamping edge 3012, thereby improving the stability of the lens 200 after installation. Meanwhile, the mounting pin 201 is located inside the lens holder 100 and is completely covered by the first clamping edge 3011 and the second clamping edge. The outer surface of the lens holder 100 is a continuous surface without a hollow structure or a groove, thereby preventing light from leaking from the joint between the lens 200 and the lens holder 100. On the other hand, the mounting pin 201 is covered, which does not affect the appearance of the lens 200 and the lens holder 100, thereby ensuring the aesthetics of the lens 200 and the lens holder 100.

[0032] Optionally, in some implementations of this embodiment, the height of the mounting pin 201 protruding from the lens 200 near the first clamping edge 3011 is greater than or equal to the height of the mounting pin 201 protruding from the lens 200 near the second clamping edge 3012 .

[0033] Please refer to Figure 3As shown, in this embodiment, the upper edge of the light outlet 101 of the lens holder 100 is set as the first clamping edge 3011, and the lower edge is set as the second clamping edge 3012. When installing the lens 200, the mounting clamping pin 201 of the upper edge of the lens 200 is firstly obliquely clamped into the first clamping edge 3011, and then the lens 200 is rotated, and the mounting clamping pin 201 of the lower edge of the lens 200 is clamped into the second clamping edge 3012, so that the installation operation is convenient and quick. Since the lens 200 is directly clamped and connected with the first clamping edge 3011 and the second clamping edge 3012 from the light outlet 101, it is also more convenient to disassemble the lens 200, and it is convenient to replace or maintain the lens 200. When installing, the mounting clamping pins 201 of the upper and lower edges of the lens 200 are clamped with the first clamping edge 3011 and the second clamping edge 3012 respectively. Theoretically, the higher the height of the mounting foot 201 protruding from the lens 200 is, the greater the interference with the lens holder 100 is, so that the clamping is more secure. Therefore, the mounting foot 201 at the upper edge of the lens 200 clamped with the first clamping edge 3011 protrudes from the lens 200 to a greater height, thereby preventing it from falling off. In order to facilitate the smooth clamping of the mounting foot 201 of the lens 200 into the lens holder 100, the mounting foot 201 at the lower edge of the lens 200 clamped with the second clamping edge 3012 protrudes from the lens 200 to a smaller height, thereby facilitating the installation and removal of the lens 200. After the lens 200 is installed, due to the self-generated weight of the lens 200, the mounting foot 201 at the lower end is always in contact with and squeezed with the second clamping edge 3012, so that even if the mounting foot 201 at the lower end of the lens 200 protrudes from the lens 200 to a smaller height, the stability of the lens 200 can be ensured.

[0034] Optionally, in some implementations of this embodiment, the first clamping edge 3011 and the second clamping edge 3012 are made of elastic material.

[0035] Please refer to Figure 3As shown, in this embodiment, the upper edge of the light outlet 101 of the lens holder 100 is the first clamping edge 3011, the lower edge is the second clamping edge 3012, and the left and right sides are the limiting edges 302. The first clamping edge 3011 and the second clamping edge 3012 are in contact with the light-emitting side of the lens 200. For example, the first clamping edge 3011 and the second clamping edge 3012 can be in contact with the side of the mounting pin 201 of the lens 200 close to the light-emitting surface. At the same time, the limiting edge 302 is in contact with the light-incoming side of the lens 200. The first clamping edge 3011, the second clamping edge 3012 and the limiting edge 302 cooperate with each other to ensure the stability of the connection between the lens 200 and the lens holder 100. The first clamping edge 3011 and the second clamping edge 3012 can be made of elastic material, and the first clamping edge 3011 and the second clamping edge 3012 protrude from the limiting edge 302, or a groove is provided at the connection between the first clamping edge 3011 and the second clamping edge 3012 and the limiting edge 302, so that the first clamping edge 3011 and the second clamping edge 3012 can undergo elastic deformation to a certain extent. When the mounting foot 201 is clamped with the first clamping edge 3011 or the second clamping edge 3012, the mounting foot 201 squeezes the first clamping edge 3011 or the second clamping edge 3012 to undergo elastic deformation, and at this time, the mounting foot 201 can be easily clamped with the lens bracket 100. After the clamping is completed, the first clamping edge 3011 or the second clamping edge 3012 is reset under the action of elastic force and firmly fixes the lens 200, so that the lens 200 is firmly installed on the lens bracket 100. When the lens 200 needs to be disassembled, a certain external force is applied to the lens 200 so that the mounting foot 201 squeezes the first clamping edge 3011 or the second clamping edge 3012 to deform and separate from the first clamping edge 3011 or the second clamping edge 3012 , thereby disassembling the lens 200 .

[0036] Optionally, in some implementations of the present embodiment, the edge of the first clamping edge 3011 and / or the second clamping edge 3012 is bent inward along the light outlet 101 to form an elastic buckle 3013 , and the elastic buckle 3013 abuts against the mounting foot 201 .

[0037] Please refer to Figure 4 and Figure 5In this embodiment, the entire edge or part of the edge of the second clamping edge 3012 is folded along the inside of the axial light outlet 101 to form an n-shaped elastic buckle 3013. When the mounting foot 201 is clamped into the second clamping edge 3012 from the outside of the light outlet 101, the mounting foot 201 is easy to squeeze the n-shaped elastic buckle 3013 to deform, which is convenient for the mounting foot 201 to be clamped. On the contrary, when the mounting foot 201 moves from the inside to the outside of the light outlet 101, the elastic buckle 3013 will limit the movement of the mounting foot 201, so as to prevent the mounting foot 201 from being separated from the second clamping edge 3012 under slight force, thereby ensuring the firmness of the connection between the lens 200 and the lens bracket 100. The elastic buckle 3013 is always in contact with the lower edge of the lens 200, which can provide a certain pre-tightening force for the lens 200, and prevent the lens 200 from shaking and affecting the lighting effect.

[0038] Optionally, in some other embodiments, the edge of the first clamping edge 3011 is also folded toward the inside of the light outlet 101 to form an elastic buckle 3013 .

[0039] Optionally, in some implementations of this embodiment, a guiding inclined surface 2011 for guiding the mounting pin 201 to snap into the snap-fit ​​portion is provided on one side of the mounting pin 201 close to the light incident surface of the lens 200 .

[0040] Please refer to Figure 5 As shown, in this embodiment, one end of the mounting pin 201 close to the light incident surface of the lens 200 is set to an inclined structure, thereby forming a guiding inclined surface 2011. When the mounting pin 201 needs to be inserted into the first clamping edge 3011 or the second clamping edge 3012, the inclined guiding inclined surface 2011 is more likely to squeeze the first clamping edge 3011 or the second clamping edge 3012 to deform, so as to facilitate the mounting pin 201 to be inserted.

[0041] Optionally, in some implementations of this embodiment, a limiting inclined surface 2012 abutting against the clamping portion is provided on one side of the mounting pin 201 close to the light-emitting surface of the lens 200 .

[0042] Please refer to Figure 5As shown, in this embodiment, the side of the mounting foot 201 close to the light-emitting surface of the lens 200 is also tilted to form a limiting inclined surface 2012, and the inclination direction of the limiting inclined surface 2012 is opposite to the inclination direction of the guiding inclined surface, and the inclination angle of the limiting inclined surface 2012 is smaller than the inclination angle of the guiding inclined surface. The inclined limiting inclined surface 2012 abuts against the edge of the elastic buckle 3013. On the one hand, the inclined limiting inclined surface 2012 facilitates the mounting foot 201 to be clamped into the second clamping edge 3012. On the other hand, the limiting inclined surface 2012 abuts against the elastic buckle 3013, which not only provides a lateral limiting force to prevent the lens 200 from falling off, but also provides an upward pre-tightening force to prevent the lens 200 from shaking or tilting, etc., which affects the lighting effect. In addition, the inclined limiting inclined surface 2012 also facilitates the disassembly of the lens 200, thereby improving the disassembly and installation efficiency of the lens 200. It should be noted that, in this embodiment, the inclination angle of the limiting slope 2012 is smaller than the inclination angle of the guiding slope. The inclination angle of the limiting slope 2012 is smaller, which prevents the installation pin 201 from falling off due to slight force. A certain force needs to be applied to remove the lens 200, so it will not affect the installation stability of the lens 200.

[0043] Optionally, in some implementations of the present embodiment, convex ribs 202 protruding from the lens 200 are provided on both sides of the lens 200, the convex ribs 202 and the light incident surface of the lens 200 form a step structure, the step structure has a step surface connecting the light incident surface and the convex ribs 202, and an axial positioning rib 400 is provided at the light outlet 101, and the axial positioning rib 400 abuts against the step surface.

[0044] Please refer to Figure 3 As shown, in this embodiment, the limiting edge 302 at the light outlet 101 is provided with a plurality of axial positioning ribs 400, and convex ribs 202 protruding from the lens 200 are provided on both sides of the lens 200. The convex ribs 202 and the light incident surface of the lens 200 form a step structure, and the step structure has a step surface connecting the light incident surface and the convex ribs 202. The axial positioning ribs 400 abut against the step surface, thereby limiting the lens 200 and preventing the lens 200 from shifting and forming a large gap between the lens holder 100 to cause light leakage.

[0045] Optionally, in some implementations of this embodiment, the inner side wall of the lens holder 100 is provided with radial positioning ribs 500, and the radial positioning ribs 500 abut against the side wall of the lens 200. The radial positioning ribs 500 cooperate with the axial positioning ribs 400 to achieve a better limiting effect and ensure the stability of the lens 200.

[0048] The vehicle lamp module provided in this embodiment adopts the above-mentioned lens assembly, and the lens 200 is installed by forming a buckle structure through the first clamping edge 3011 and the second clamping edge 3012 of the flanged type, which is convenient for assembly and disassembly.

The buckle structure is integrated with the lens holder 100, and the outer surface of the lens holder 100 is a continuous surface.
