[0003] The reflector is an important part of the headlight. Due to its specific purpose in the headlight, the structure of the reflector itself and its installation and positioning with other components have a very important impact on the performance of the entire headlight. At present, the design and development of the reflector still focuses on improving its optical performance, while the coordination effect of the reflector and other components when installed and the structural stability during use are less concerned.

[0004] Therefore, after the existing reflector structure and other components are installed and positioned, they are easily displaced due to the shaking of the car during driving, affecting the lighting or signal function of the car lamp. Utility Model Content

[0014] More preferably, the side wall reflectivity of the retaining wall is 5-15%, and / or a pattern structure is provided on the side surface of the retaining wall, and / or at least one through hole is provided on the retaining plate.

[0015] Specifically, an outer wall of a connection between at least one of the mounting portion and the light-isolating portion and the reflector is concave.

[0016] More specifically, the thickness of a connection between at least one of the mounting portion and the light-isolating portion and the reflector is 20-50% of the thickness of other regions of the reflector.

After displacement due to shaking during vehicle driving, the light reflecting element can be restored along with the elastic structure to ensure the lighting or signal function of the car light.

[0042] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0043] First of all, it should be explained that in the following description, some directional words, such as "front", "rear", "up", "down", "left", "right", etc., are involved in order to clearly explain the technical solution of the utility model. Based on the headlights, "front" refers to the direction indicated by the light-emitting direction of the headlights, "rear" refers to the direction opposite to "front", "left" refers to the left side along the light-emitting direction of the headlights, "right" refers to the right side along the light-emitting direction of the headlights, that is, the same as the left and right sides of the vehicle when it is driving normally, "up" refers to the upper side along the light-emitting direction of the headlights, and "down" refers to the lower side along the light-emitting direction of the headlights. The terms are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the utility model.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "contact", and "connection" should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The first aspect of the utility model provides a light reflecting element 1, see Figures 1 to 10, connected to the matching element when in use, the light reflecting element 1 includes a reflecting portion 11 and a mounting portion 12 connected to the reflecting portion 11, the light reflecting element 1 can be connected to the matching element through the mounting portion 12, at least one elastic structure 13 is provided on the side of the mounting portion 12 facing the matching element, and the thickness of the intersection of the elastic structure 13 and the mounting portion 12 is less than the thickness of the mounting portion 12.

[0046] In the present invention, the light reflecting element 1 can be used to directly reflect and transmit the light emitted by the light source 2 in the vehicle lamp, and can also be used to reflect and transmit the light after being converged or transmitted by other optical elements. The matching element can be selected according to the light transmission function of the light reflecting element 1 in the vehicle lamp and the installation method, so as to fix and install the light reflecting element 1 through the installation part 12. For example, the matching element can be a circuit board 3, a heat sink 4, a lens bracket, etc.

[0047] The light reflecting element 1 provided by the basic technical scheme of the utility model is provided with an elastic structure 13 on the side of the mounting portion 12 facing the matching element, and the thickness of the intersection of the elastic structure 13 and the mounting portion 12 is less than the thickness of the mounting portion 12, so that the elastic structure 13 is weakened by the local wall thickness around it, weakening its strength, increasing the deformability of the elastic structure 13, helping the light reflecting element 1 to be better installed and positioned with the matching element, and improving the structural stability after installation. After displacement due to shaking during vehicle driving, it can be restored with the elastic structure 13. When used in a vehicle light module, the light shape accuracy of the vehicle light module can be guaranteed, thereby improving the light shape stability of the vehicle; when used in various types of signal lights, the stability of the signal lighting function of various types of signal lights can be guaranteed.

[0048] In the present invention, the intersection of the elastic structure 13 and the mounting portion 12 refers to the connection between the periphery of the elastic structure 13 and the mounting portion 12; the elastic structure 13 can be an elastic block embedded in the mounting portion 12 and made of elastic material as a whole, or a raised block provided on the mounting portion 12, the part of the raised block close to the mounting portion 12 is made of the same material as the mounting portion 12, and the part away from the mounting portion 12 is made of elastic material. Preferably, the elastic structure 13 is set as a raised elastic block located on the side of the mounting portion 12 facing the mating element, and the local wall thickness of the intersection of the raised elastic block and the mounting portion 12 is thinned, which is conducive to further improving the deformation degree of the elastic structure 13 and improving the recovery ability of the light reflecting element 1 to shaking and offset. Among them, the raised elastic block can be set on the main body of the mounting portion 12, or an extension block can be set on one side of the main body of the mounting portion 12, and the raised elastic block is set on the extension block, so as to be more flexible in installation and connection with the mating element.

[0049] In the present invention, the elastic structure 13 and the matching element are installed to form a butting connection mode, and the matching element can be further connected with other elements. The pressing force of the elastic structure 13 on the matching element can make the matching element and other elements stably installed and fixed. As a preferred embodiment, see Figures 8 to 10 The elastic structure 13 is designed to be in interference connection with the matching element, which helps the light reflecting element 1 to better press the matching element and other elements, and the installation structure is more stable.

[0050] In the present invention, interference connection means that after the elastic structure 13 and the matching element are installed, the elastic structure 13 has a certain radial deformation so that a large pressure is generated between the contact surface with the matching element. The interference amount of the elastic structure 13 can be specifically designed according to the material properties of the elastic structure 13, the type of the matching element and the matching relationship with other elements. For example, the interference amount of the elastic structure 13 is 0.1 to 0.3 mm.

[0051] As a preferred embodiment of the mounting portion 12 in the present invention, at least one zero-surface reference block 14 is also provided on the side of the mounting portion 12 facing the mating element, so as to facilitate positioning of the light reflecting element 1 and the mating element. A plurality of zero-surface reference blocks 14 can be provided, and distributed on two opposite sides of the mounting portion 12.

[0052] As another preferred embodiment, the mounting portion 12 is provided with at least one positioning hole 15 for fixed connection with the matching element. Correspondingly, the matching element may also be provided with a corresponding mounting hole, so that the light reflecting element 1 and the matching element are fixedly mounted by the fastener in the positioning hole 15, and the elastic structure 13 is abutted against the matching element; for example, the fastener may be a screw, a bayonet, etc. When the mounting portion 12 is provided with both the zero-surface reference block 14 and the positioning hole 15, the zero-surface reference block 14 is first used for positioning, and then the fastener is installed in the positioning hole 15 so that the light reflecting element 1 and the matching element form a stable connection structure. The positioning holes 15 may be provided in plurality and distributed on opposite sides of the mounting portion 12.

[0053] In the present invention, the structure of the reflective part 11 can have a single reflector 16 or a plurality of parallel reflectors 16. The reflective surface of the reflector 16 can be a plane or a curved surface. Preferably, the reflective surface of the reflector 16 is in the shape of a parabola or an ellipsoid. As a preferred embodiment of the light reflecting element 1, the reflective part 11 includes a plurality of reflectors 16 connected in sequence along the left-right direction. A light-isolating part is provided on the side of the reflective part 11 facing away from the mounting part 12. The light-isolating part can separate the reflective cavities corresponding to the respective reflectors 16 from each other to avoid the cross-interference of the light reflected by the adjacent reflectors 16 to form the mutual influence of stray light.

[0054] Preferably, the light-isolating portion includes a baffle 17 connected to the reflecting portion 11 and a baffle 18 disposed on the baffle 17, and the baffle 18 is located at the junction of two adjacent reflectors 16. The baffle 17 is connected to the side of the reflecting portion 11 facing away from the mounting portion 12, and the number of baffles 18 matches the number of reflectors 16, which is generally one less than the number of reflectors 16. The size (including height and width) of the baffle 18 can be designed accordingly according to the size of the light-reflecting element 1, so as to be able to block stray light between the reflective cavities of the multiple reflectors 16, for example, the height of the baffle 18 can be 10 to 35 mm, and the width can be 0.8 to 2 mm.

[0055] In the present invention, the baffle 18 should not affect the overall transmission direction of the outgoing light of the corresponding reflector 16, and thus the side wall reflectivity of the baffle 18 is preferably 5-15%; at the same time, a pattern structure is provided on the side of the baffle 18 to further remove stray light in the reflection cavity.

[0056] As a preferred embodiment of the baffle 17, see Figure 6 and Figure 7 At least one through hole 19 is provided on the baffle 17. The provision of the through hole 19 can not only reduce the overall weight of the light reflecting element 1, which is beneficial to the lightweight design of the vehicle lamp, but also realize air convection between the inside and outside of the light reflecting element 1, thereby increasing the heat dissipation effect.

[0057] As another preferred embodiment of the light reflecting element 1, the outer wall of the connection between at least one of the mounting portion 12 and the light isolating portion and the reflector 16 is concave, so that the wall thickness of the connection between the reflector 16 and other structures of the light reflecting element 1 is reduced along the circumference, thereby preventing the surface of the front surface a of the reflective surface of the reflector 16 from shrinking and causing poor quality. Preferably, the thickness of the connection between at least one of the mounting portion 12 and the light isolating portion and the reflector 16 is 20-50% of the thickness of other areas of the reflector 16. Exemplarily, the thickness of the main body of the reflector 16 is 2 mm, and the thickness reduction value of the connection between the reflector 16 and the mounting portion 12 and / or the light isolating portion is 1-1.6 mm.

[0059] Generally, when the reflective portion 11 directly reflects the light from the light source 2 , the light source 2 is arranged with its light emitting surface facing the reflective surface of the reflective portion 11 .

[0060] As a preferred embodiment, see Figures 8 to 10 , the matching component is a circuit board 3, the light source 2 is mounted on the circuit board 3, one side of the circuit board 3 is connected to the mounting portion 12, and the other side is connected to the heat sink 4. The elastic structure and deformability of the light reflecting element 1 can effectively press the circuit board 3 and the heat sink 4 into contact; when the raised elastic block and the matching component are in interference connection, it helps the light reflecting element 1 to better press the circuit board 3 and the heat sink 4. When the mounting portion 12 is provided with a positioning hole 15, corresponding mounting holes are provided on the circuit board 3 and the heat sink 4 to be installed and fixed by fasteners such as screws.

[0062] In the above-mentioned headlight, when installing the light reflecting element 1, the circuit board 3 and the radiator 4, the light reflecting element 1 is first positioned using the zero-surface reference block 14, and then the fastener screws are screwed into the positioning holes 15, the mounting holes on the circuit board 3 and the mounting holes on the radiator 4 in turn, and the circuit board 3 and the radiator 4 are pressed tightly using the interference of the raised elastic block, so that the light reflecting element 1, the circuit board 3 and the radiator 4 form a stable mounting structure. During use, the light emitted by the light source 2 is reflected by the corresponding reflector 16, and the retaining wall 18 can separate the light between adjacent reflection cavities to avoid the influence of stray light between the reflection cavities; after displacement due to shaking during vehicle driving, it can be restored with the raised elastic block.
