[0047] The utility model discloses a vehicle lamp, which improves the accuracy of installing a lens and a lamp panel, so as to improve the optical performance of the vehicle lamp. In addition, the utility model also discloses a vehicle with the vehicle lamp.

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0050] Car lights are very important for road safety and play a significant role in guiding following vehicles and pedestrians. In addition, they are even more important at night and in conditions with poor visibility such as heavy fog.

[0051] Current headlights usually include a lens, a light board and a radiator, wherein the lens and the radiator are respectively arranged on both sides of the light board, and the light emitted by the light source of the light board is irradiated to the outside of the headlight through the lens to realize the lighting function or signal indication function of the headlight.

[0052] By adjusting the position of the lens relative to the light source, the light pattern and brightness of the light source can be changed. Based on this, during the installation of the lens and the light board, the accuracy of the distance between the two is required to be relatively high. At present, the lens is usually bonded to the light board, but the bonding method easily leads to inaccurate distance between the lens and the light board, that is, the lens is offset or deflected relative to the light board, which affects the optical performance of the headlight.

[0053] Based on this, in the present application, the distance between the lens and the light board is adjustable, and the two can be relatively fixed, so as to improve the accuracy of the distance between the lens and the light board and improve the optical performance of the car light.

[0054] like Figures 1 to 10 As shown, the vehicle lamp in the present application includes a lens 1, a light board 2, a heat sink 3 and a locking member 4. Among them, the light board 2 is fixed on the heat sink 3 to form a light module 200. During the assembly of the vehicle lamp, the light board 2 is pre-installed on the heat sink 3. It can be understood that during the installation of the lens 1, the light board 2 and the heat sink 3 are as a whole. By fixing the light board 2 on the heat sink 3, it is prevented that the light board 2 is tilted or offset during the installation of the light board 2 and the lens 1, thereby affecting the accuracy of the relative position between the light board 2 and the lens 1. The connection method between the light board 2 and the heat sink 3 includes but is not limited to fixed connection with screws. When the vehicle lamp is assembled, the lens 1, the light board 2 and the heat sink 3 are arranged in sequence along the first direction.

[0055] The lens 1 has a mounting post 11 extending along a first direction on one side close to the lamp board 2. The lighting module 200 after the lamp board 2 and the heat sink 3 are connected has an assembly hole 21 extending along the first direction. The mounting post 11 can be inserted into the assembly hole 21, and the distance that the mounting post 11 extends into the assembly hole 21 is adjustable. When the mounting post 11 is inserted into the assembly hole 21 so that the distance between the lens 1 and the lamp board 2 reaches the desired position, the mounting post 11 is locked in the assembly hole by a locking member to achieve relative fixation of the lens 1 and the lamp board 2.

[0056] It can be known from the above description that the vehicle lamp disclosed in the present application is achieved by pre-assembling the lamp board 2 to the radiator 3, and assembling and connecting the lens 1 and the lamp board 2 through the mounting column 11 and the assembly hole 21, and adjusting the depth of the mounting column 11 extending into the assembly hole 21 during the assembly process of the lens 1 and the light board 2 to adjust the distance between the lens 1 and the light board 2, thereby improving the accuracy of the distance between the lens 1 and the light board 2 and improving the optical performance of the vehicle lamp.

[0057] See also Figures 2 to 6 As shown, the lens 1 in the present application includes: a lens body 12 and a lens bracket 13. The lens body 12 is mounted on the lens bracket 13, and the connection method between the lens body 12 and the lens bracket 13 includes but is not limited to bonding or clamping. The lens body 12 is located on one side of the lens bracket 13, and the mounting column 11 is located on the other side of the lens bracket 13.

[0058] The lens body 12 is an optical element as a light emitting component, including but not limited to a reflector. Of course, the lens body 12 can also be a combination of multiple lenses. For the structure and connection relationship of the lens body 12, refer to the lens of the existing headlight. The lens bracket 13 is an annular structure. The edge of the lens body 12 is adjacent to the lens bracket 13, and the lens body 12 is opposite to the hollow position of the annular structure to avoid the lens bracket 13 blocking the lens body 12 and affecting the light emitting area of ​​the light source of the lamp board 2. The lens bracket 13 includes but is not limited to an injection molded part, and its shape can be a rectangular ring or a circular ring, and the specific shape can be selected according to different needs.

[0059] In order to improve the stability of the lens 1 after being connected to the light board 2, a fitting surface can be provided on one side of the lens bracket 13 where the mounting post 11 is provided. By fitting the fitting surface to the light board 2, the stability of the lens 1 and the light board 2 after installation is improved to prevent the position of the lens 1 from changing. It should be noted that when the fitting surface is fitted to the light board 2, the depth of the mounting post 11 extending into the assembly hole 21 is just enough to meet the distance between the light board 2 and the lens 1.

[0060] The fitting surface disclosed in some embodiments has a first groove 131 arranged along the circumferential direction, and the first groove 131 is used to set the elastic seal; the fitting surface has a second groove 132, the second groove 132 is close to the inner circle of the lens holder 13, and the mounting column 11 is installed at the groove bottom of the second groove 132. The elastic seal is arranged in the first groove 131, which can realize the fitting and sealing of the lens holder 13 of the lens 1 and the light board 2, and effectively prevent the lens body 12 from being contaminated by dust or water stains.

[0061] Exemplarily, the fitting surface is a rectangular ring structure, the first groove 131 is a rectangular ring, and the second groove 132 is a convex structure of the inner ring of the fitting surface. In some embodiments, four convex structures are arranged in the circumference of the inner ring of the fitting surface, and each convex structure is provided with a mounting post 11, that is, all mounting posts 11 are arranged in a rectangular shape. In order to improve the stability of the connection between the lens 1 and the light board 2, four assembly holes 21 are provided on the light module 200 (see Figure 7 ), and these assembly holes 21 are also arranged in a rectangular shape, so that the mounting posts 11 are arranged one-to-one with the assembly holes 21. By increasing the number of mounting posts 11 and assembly holes 21, the stability of the lens 1 and the light board 2 after assembly can be improved, and during the installation process of the light board 2 and the lens 1, adjacent mounting posts 11 can be mutually limited to improve the accuracy of positioning the light board 2 and the lens 1 in a direction perpendicular to the first direction.

[0062] It should be noted that the number of mounting columns 11 and assembly holes 21 can be set according to different needs. Optionally, there are at least two mounting columns 11, and at least two mounting columns 11 correspond one-to-one to the assembly holes 21, and the mounting columns 11 are distributed circumferentially along the bottom of the second groove 132.

[0063] In some embodiments, the second groove 132 is located in the inner circle of the first groove 131, and the height of the inner groove wall of the first groove 131 close to the second groove 132 is the same as the height of the outer groove wall of the first groove 131 away from the second groove 132. Setting the inner groove wall and the outer groove wall of the first groove 131 to the same height can increase the contact area when the light board 2 and the lens 1 are attached, which is conducive to preventing the lens 1 from tilting relative to the light board 2.

[0064] Combination Figure 6 and Figure 7 As shown, the mounting column 11 includes: a first portion 111 and a second portion 112. The first portion 111 and the second portion 112 are both fixed to the lens bracket 13, and there is a gap between the first portion 111 and the second portion 112. The locking member 4 can extend between the first portion 111 and the second portion 112, and can squeeze the first portion 111 and the second portion 112 to increase the distance between the first portion 111 and the second portion 112, so that the first portion 111 and the second portion 112 are locked in the assembly hole 21.

[0065] The first part 111 and the second part 112 in the present application may be injection molded parts. In some embodiments, the mounting column 11 may be integrally formed with the lens bracket 13. The opposing surfaces of the first part 111 and the second part 112 may be planes, and the distance between the two is smaller than the size of the portion of the locking member 4 extending into the first part 111 and the second part 112. For example, if the locking member 4 is a screw, the distance between the first part 111 and the second part 112 is smaller than the diameter of the screw.

[0066] The distance between the first part 111 and the second part 112 needs to be ensured to be increased after the locking member 4 is inserted therebetween, and the first part 111 and the second part 112 after the increased distance are interference fit with the assembly hole 21 to achieve the fitting connection between the mounting column 11 and the assembly hole 21.

[0067] In some embodiments, the outer wall of the first part 111 and / or the second part 112 has a convex rib 1121 protruding in a direction away from the other, and the assembly hole 21 has a guide groove adapted to the convex rib 1121, and the mounting column 11 and the assembly hole 21 are positioned and assembled through the convex rib 1121 and the guide groove. The position accuracy of the mounting column 11 and the assembly hole 21 during the installation process can be ensured by the definition of the convex rib 1121 and the guide groove, and the relative rotation of the lens 1 and the lighting module 200 during the installation process can be avoided, which affects the gap between the first part 111 and the second part 112 facing the locking member 4.

[0068] The rib 1121 may be a long strip structure extending along the length direction of the mounting column 11. In some embodiments, the size of the end of the mounting column 11 away from the lens bracket 13 gradually increases from the end toward the lens bracket 13 to facilitate the insertion of the mounting column 11 into the assembly hole 21.

[0069] Combination Figure 8 and Fig. 9 As shown, the radiator 3 includes: a heat exchange surface 31 and heat dissipation fins 32. The lamp board 2 is fixedly connected to the heat exchange surface 31. Optionally, the side of the heat exchange surface 31 opposite to the lamp board 2 is a flat plate to increase the contact area between the lamp board 2 and the radiator 3, improve the stability of the lamp board 2 after installation, and help avoid the position of the lamp board 2 from being offset and affecting the position relationship between the lamp board 2 and the lens 1.

[0070] The heat dissipation fin 32 is located on the side of the heat exchange surface 31 away from the lamp board, and the assembly hole 21 extends to the heat dissipation fin 32, and the assembly hole 21 is a blind hole. The heat dissipation fin 32 has a threaded hole 22 arranged to intersect with the axis of the assembly hole 21. The locking member 4 extends into the assembly hole 21 through the threaded hole 22 and abuts against the mounting column 11. Optionally, the threaded hole 22 is arranged vertically with the assembly hole 21 to facilitate the rotation of the locking member 4. Through the cooperation between the locking member 4 and the threaded hole 22, the locking member 4 is fixed to the radiator 3 during the rotation of the locking member 4 relative to the threaded hole 22, and the locking member 4 abuts against the mounting column 11, thereby increasing the distance between the first part 111 and the second part 112, so that the mounting column 11 is connected with the assembly hole 21. The cooperation between the locking member 4 and the threaded hole 22 can improve the stability of the cooperation between the mounting column 11 and the assembly hole 21.

[0071] It should be noted that when the rib 1121 and the guide groove are provided, the gap between the first portion 111 and the second portion 112 is opposite to the threaded hole 22 .

[0072] In the example, the assembly hole 21 is a circular hole, and / or the assembly hole 21 is arranged along the circumference of the lamp beads of the lamp board 2, such as Figure 8 shown.

[0073] In addition, the present application also discloses a vehicle, including a headlight, wherein the headlight is the headlight disclosed in the above embodiment. Therefore, the vehicle with the headlight also has all the above technical effects, which will not be described one by one here.
