[0041] 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.

[0042] 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.

[0043] For vehicle lights, a lot of heat will be generated during the long-term operation of the lighting module. If the heat cannot be dissipated in time, the use of the vehicle lighting module will be affected. Based on this, the current vehicle lights will connect the lighting module with a radiator, and the heat dissipation of the lighting module of the vehicle lights is achieved through the fit between the radiator and the lighting module, thereby ensuring the normal use of the lighting module.

[0044] As the performance requirements of lighting modules become higher and higher, conventional heat sinks can no longer meet the heat dissipation needs of lighting modules, and additional fans are needed to assist the heat sink in dissipating the heat of the lighting modules.

[0045] During the installation of existing fans in lighting modules, screws are usually used to install them on the fan mounting frame of the lighting module. However, since a large operating space is required during the screw connection process and the lighting module itself has a small space, it brings great difficulties to the operator and affects the assembly efficiency of the fan.

[0046] Based on the above problems, the present application discloses a fan assembly, which clips the fan onto the fan mounting frame, i.e., uses clip-on connection instead of screw connection, thereby reducing the space requirement for the screw connection process. The clip-on operation is simple and has small space requirements, which can reduce the difficulty of operation and is beneficial to improving the assembly efficiency of the fan.

[0047] Combination Figure 1 , Figure 2 and Fig. 9 As shown, the fan assembly in the present application includes: a fan 2, a fan mounting frame 1 and a power module 3. The fan 2 is snapped onto the fan mounting frame 1. Specifically, the fan mounting frame 1 has a receiving groove, the bottom of which is a hollow annular structure, and a group of opposite side walls of the receiving groove have a first snap 11 and a second snap 19. The fan 2 can be installed in the receiving groove, and one end face of the fan 2 in the thickness direction abuts against the bottom of the receiving groove, and the blades 22 of the fan 2 are opposite to the hollow position of the bottom of the groove, and a group of opposite side edges of the other end face in the thickness direction of the fan 2 are snapped by the first snap 11 and the second snap 19 along the circumferential direction, respectively, so that the fan 2 is limited along the thickness direction of the fan 2 under the limitation of the first snap 11, the second snap 19 and the bottom of the groove. The circumferential side of the fan 2 abuts against the side wall of the receiving groove, thereby fixing the fan 2 on the fan mounting frame 1.

[0048] The fan 2 is electrically connected to the power module 3 so that the fan 2 is powered by the power module 3 to achieve normal driving of the fan 2.

[0049] In the present application, the fan 2 is snap-connected to the fan mounting bracket 1, that is, snap-connection is used instead of screw connection, thereby reducing the space requirement required for the screw connection process. In addition, the snap-connection operation is simple and requires little space, which can reduce the difficulty of operation and is beneficial to improving the assembly efficiency of the fan 2.

[0050] Combination Figures 3 to 6 As shown, the fan mounting bracket 1 in the present application is provided with a positioning column 12, a positioning groove 13, a first limiting rib 14, a second limiting rib 16, a third limiting rib 17, a fourth limiting rib 18 and a mounting hook 15 on the bottom of the groove.

The number of the first limiting ribs 14 can be set according to different needs. For example, at least two first limiting ribs 14 can be set on the side walls where the first limiting ribs 14 are set. When the fan 2 is installed in the installation groove, the first limiting ribs 14 of the two side walls can clamp the fan to achieve the limitation of the fan in the connection manner of the two side walls.

[0052] The side of the receiving groove where the second buckle 19 is located is provided with a second limiting rib 16. Exemplarily, there are at least two second limiting ribs 16, which are distributed on both sides of the second buckle 19. Optionally, the second buckle 19 is located in the middle of the side where the second limiting rib 16 is located, and the second limiting rib 16 is symmetrically arranged about the second buckle 19 to improve the stability of the installation of the fan 2 and prevent the fan 2 from tilting.

[0053] A third limiting rib 17 is provided on the side of the receiving groove where the first buckle 11 is located. Exemplarily, there are at least two third limiting ribs 17, which are distributed on both sides of the first buckle 11. Optionally, the first buckle 11 is located in the middle of the side where it is located, and the third limiting rib 17 is symmetrically arranged about the first buckle 11; a fourth limiting rib 18 is provided on the inner wall of the first buckle 11, and there can be two fourth limiting ribs 18.

[0054] A set of side walls of the fan 2 (side walls where the first buckle 11 and the second buckle 19 are provided) are abutted against the second limiting rib 16, the third limiting rib 17 and the fourth limiting rib 18, so as to limit the fan 2 along the connecting line direction of the set of side walls. It can be understood that the second limiting rib 16 abuts against one side wall of the fan 2, and the other side wall of the fan 2 abuts against the third limiting rib 17 and the fourth limiting rib 18 at the same time.

[0055] The first limiting rib 14, the second limiting rib 16, the third limiting rib 17 and the fourth limiting rib 18 are respectively formed integrally with the groove wall of the accommodating groove, and the sizes of the first limiting rib 14, the second limiting rib 16, the third limiting rib 17 and the fourth limiting rib 18 can be set according to different needs and are all within the protection range. The fan mounting bracket can be an injection molded part.

[0056] The mounting hook 15 is arranged on the fan mounting frame 1, and is used to clamp and limit the wiring harness of the power module 3, so as to prevent the wiring harness from shaking and affecting the stability of the connection between the power module 3 and the fan 2, and to improve the aesthetics.

[0057] Combination Figures 3 to 8As shown, a positioning column 12 is provided at the bottom of the accommodating groove, and the fan 2 has a positioning hole 211 that can be positioned and connected with the positioning column 12; and / or, a positioning groove 13 is provided at the bottom of the accommodating groove, and the fan 2 has an adjusting member 212 that can be counteracted with the positioning groove 13, and the adjusting member 212 can adjust the distance of the fan 2 relative to the bottom of the accommodating groove.

[0059] The setting of the adjusting member 212 can adjust the distance between the fan 2 and the bottom of the accommodating groove, and can ensure that during the assembly process of the fan 2, when the first buckle 11 and the second buckle 19 are deformed and engaged with the fan 2, the moving distance of the fan 2 can complete the deformation of the first buckle 11 and the second buckle 19, and under the action of the adjusting member 212, a force is applied to the fan 2 in the limiting direction of the first buckle 11 and the second buckle 19 to ensure the installation stability of the fan 2. Based on this, the adjusting member 212 can be an elastic member or a screw connected by a retaining spring. Of course, the adjusting member 212 can only be a screw, and the assembly of the fan 2 is ensured by turning the screw.

[0060] In some embodiments, the positioning grooves 13 and the positioning posts 12 are arranged in a rectangular shape and are arranged alternately along the circumference of the rectangle. Exemplarily, the receiving groove is a rectangular groove, the positioning grooves 13 and the positioning posts 12 are both arranged at the top corners of the rectangular groove, and the positioning grooves 13 are arranged on one diagonal line of the rectangular groove, and the positioning posts 12 are arranged on the other diagonal line of the rectangular groove.

Exemplarily, the mounting seat is arranged on both sides of the opposite side walls of the fan mounting frame 1 where the first buckle 11 and the second buckle 19 are not provided, and the connection direction of the first buckle 11 and the second buckle is arranged obliquely relative to the mounting surface 10.

[0062] The inclination angle of the connecting line of the first buckle 11 and the second buckle relative to the mounting surface 10 can be set according to different needs and is not specifically limited here.

[0063] Combination Fig. 9As shown, the first buckle 11 and / or the second buckle 19 are protrusions protruding from the side wall of the accommodating groove, and the protrusions and the side wall of the accommodating groove form a step, and the step abuts against the end surface of the fan 2. The specific shapes of the first buckle 11 and the second buckle 19 can be set according to different needs, as long as the shapes that can achieve the limited clamping connection between the fan 2 and the fan mounting frame 1 are within the protection range.

[0064] Combination Figure 7 and Figure 8 As shown, the fan 2 includes a fan frame 21 and blades 22. The blades 22 are mounted on the fan frame 21. The blades 22 are opposite to the hollow position of the receiving groove to ensure that wind disturbance is formed during the rotation of the blades 22. The fan frame 21 includes but is not limited to a rectangular frame. For example, the first limiting rib 14 and the second limiting rib 16 can be rectangular columns perpendicular to the bottom of the groove, and the rectangular columns are used to fit the outer wall of the fan frame 21.
