[0033] The present invention discloses a lamp housing assembly of a vehicle lamp to reduce the processing costs of the radiator and the lamp housing. In addition, the present invention also discloses a vehicle lamp having the above-mentioned lamp housing assembly, and a vehicle having the vehicle lamp.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] With the intensification of competition in the automotive industry, the requirements for the exterior parts of vehicles are getting higher and higher, especially the cost requirements for vehicle lights are getting higher and higher.

[0036] As Figure 1 shown, a vehicle light generally includes a radiator 100, a lamp housing 200, a PCB board 300, a lens 400, a decorative frame 500, and a lamp cover 600.

[0037] Among them, the lamp housing 200 serves as the installation foundation of the entire vehicle light, and is used to install the radiator 100, the PCB board 300, the lens 400, the decorative frame 500, and the lamp cover 600, and the lamp housing 200 is fixedly connected to the vehicle body.

[0038] The PCB board 300 is installed on one side of the lamp housing 200, and lamp beads are arranged on the PCB board 300 to realize the lighting function of the vehicle light. The lens 400 is installed with the lamp housing 200 and covers the outside of the PCB board 300, and the irradiation range of the vehicle light is adjusted through the lens 400. The decorative frame 500 and the lamp cover 600 cover the outside of the lens 400 and are detachably connected to the lamp housing 200 to protect the lens 400 inside the vehicle light. The radiator 100 is connected to the side of the lamp housing 200 away from the PCB board 300, and the radiator 100 is in contact with the PCB board 300 to dissipate the heat generated by the PCB board 300.

[0039] In some embodiments, the radiator 100 and the lamp housing 200 are processed separately, that is, the radiator 100 is separately molded and processed, and the lamp housing 200 is separately molded and processed. Exemplarily, the radiator 100 is a die-cast aluminum part, that is, by means of die-casting molding, the radiator 100 needs to be separately molded. The lamp housing 200 is an injection molded part with a plastic structure, and the lamp housing 200 needs to be separately molded. The method of separately molding and processing the radiator 100 and the lamp housing 200 has a high cost.

[0040] During the assembly process of the vehicle light, the separately processed radiator 100 and lamp housing 200 are fixedly connected, and during the assembly process, a sealing member is used to ensure the sealing performance of the connection position between the radiator 100 and the lamp housing 200. Due to the use of the sealing member, the processing cost of the vehicle light will increase, and the sealing member is a consumable part, which will also increase the use cost of the vehicle light.

[0041] In addition, the assembly process of the radiator 100 and the lamp housing 200 is relatively complex, resulting in low assembly efficiency of the vehicle light.

[0042] Based on the above problems, Figure 2 and Figure 3 the embodiments shown disclose a lamp housing assembly of a vehicle light, including a radiator 100 and a lamp housing 200.

[0043] Among them, the radiator 100 and the lamp housing 200 are integrally formed. Exemplarily, the radiator 100 and the lamp housing 200 are injection molded. During the injection molding process, the radiator 100 is first processed by die casting, and then the lamp housing 200 is injection molded on the outer side of the radiator 100, thereby forming a lamp housing assembly. That is, the radiator 100 and the lamp housing 200 in the present application are integrally formed by insert injection molding.

[0044] The radiator 100 and the lamp housing 200 in the present application are injection molded by insert injection molding, which belongs to a secondary molding process. Only the lamp housing 200 needs to be molded, reducing the molding cost. Moreover, the die-cast radiator 100 and the injection-molded lamp housing 200 can achieve a sealed connection during the injection molding process. Therefore, the use of seals can be reduced, effectively reducing the processing cost of the vehicle lamp. In addition, since the radiator 100 and the lamp housing 200 are injection molded by insert injection molding, the use of connectors can be reduced, reducing costs and also reducing the assembly of the two, which is conducive to improving the assembly efficiency of the vehicle lamp.

[0045] As Figure 4 shown, the radiator 100 includes a radiator body 101 and heat dissipation fins 102.

[0046] Among them, the radiator body 101 and the heat dissipation fins 102 are injection molded. The radiator body 101 includes, but is not limited to, a plate structure, and a heat conduction surface capable of contacting the PCB board 300 for heat transfer is formed on one side. The heat dissipation fins 102 are perpendicular to the radiator body 101. Exemplarily, the heat dissipation fins 102 are serrated heat dissipation fins, and there are two groups of heat dissipation fins 102, which are distributed at opposite ends of the radiator body 101.

[0047] The use of serrated heat dissipation fins 102 can increase the length of the heat dissipation fins 102, which is beneficial to increasing the heat dissipation area of the heat dissipation fins 102. The distribution of the heat dissipation fins 102 at both ends of the radiator body 101 can be beneficial to increasing the heat dissipation area, and the two groups of heat dissipation fins 102 are arranged at a long distance, which can avoid the mutual influence of the heat dissipation of the two groups of heat dissipation fins 102 and improve the heat dissipation efficiency.

[0048] The shape, size, and arrangement manner of the heat dissipation fins 102 on the radiator body 101 can be set according to different needs, and all are within the protection scope.

[0049] In some embodiments, the radiator 100 is formed by stamping, with a simple structure and low processing cost. The shape and size of the radiator 100 can be set according to different needs, and all are within the protection scope.

[0050] As Figure 5 and Figure 6As shown, the lamp housing 200 in the present application includes a lamp housing main body 201, connecting lugs 202, a mounting base plate 203, and a wrapping wall 204.

[0051] Among them, connecting lugs 202 are provided on the outer side of the lamp housing main body 201, and the lamp housing 200 can be connected to the vehicle body through the connecting lugs 202. The connection method between the connecting lugs 202 and the vehicle body includes but is not limited to screw connection. There can be multiple connecting lugs 202, which are arranged circumferentially along the lamp housing 200. The lamp housing main body 201 is connected to the edge of the mounting base plate 203, forming a space for accommodating the above-mentioned PCB board 300 and lens 400, and the lamp housing main body 201 is detachably connected to the decorative frame 500 and the lamp cover 600.

[0052] The shape of the lamp housing main body 201 can be set according to different needs. Exemplarily, in this article, the vehicle lamp is a circular lamp. Correspondingly, the lamp housing main body 201 is an annular structure, and the mounting base plate 203 is inside the lamp housing main body 201 and integrally formed to form a cylindrical mounting space. The PCB board 300 can be fixedly connected to the mounting base plate 203, and the required circuits and connection structures for the vehicle lamp can be provided on the mounting base plate 203. The connecting lugs 202 are arranged on the outer side of the lamp housing main body 201 and are arranged circumferentially along the lamp housing main body 201.

[0053] Combined with Figures 2 to 5 As shown, during the injection molding of the lamp housing 200 on the outer side of the stamping-molded radiator 100, the heat-conducting surface 1011 of the radiator main body 101 of the radiator 100 is exposed. It should be noted that the heat-conducting surface 1011 is the side of the radiator main body 101 away from the heat-radiating fins 102. The exposed heat-conducting surface 1011 can be used to fit with the PCB board 300 to achieve heat transfer.

[0054] The mounting base plate 203 is wrapped around the outer side of the radiator main body 101 and becomes a flat structure for installing other components.

[0055] Figure 6 As shown in, other structures required for the lamp housing 200 are provided on the side of the mounting base plate 203 away from the PCB board 300, which are not specifically limited herein as long as they are for the lamp housing 200 of the vehicle lamp. Exemplarily, the side of the mounting base plate 203 away from the PCB board 300 has a wrapping wall 204, and the wrapping wall 204 is used to wrap the connection position between the heat-radiating fins 102 and the radiator main body 101 of the radiator 100 to ensure the stability of the connection between the heat-radiating fins 102 and the lamp housing 200.

[0056] In some embodiments, each group of heat-radiating fins 102 is wrapped with a wrapping wall 204, and the area of the wrapping wall 204 wrapped on the heat-radiating fins 102 can be set according to different connection strength requirements and is within the protection range.

[0057] Combined withFigure 7 and Figure 8 As shown in Figure 8 , during the injection molding process of the lamp housing 200 and the radiator 100, the injection molding material only fills the position of the heat dissipation fins 102 close to the radiator main body 101, preventing the lamp housing 200 from completely covering the radiator 100 and avoiding affecting the heat dissipation effect of the radiator 100. It can be understood that the heat dissipation fins 102 are exposed outside the lamp housing 200 through the wrapping wall 204.

[0058] In addition, this application also discloses a vehicle lamp, including a lamp housing assembly, a PCB board 300, a lens 400, a decorative frame 500, and a lamp cover 600.

[0059] Among them, the PCB board 300 is installed on one side of the lamp housing 200, and lamp beads are arranged on the PCB board 300 to realize the lighting function of the vehicle lamp. The lens 400 is installed with the lamp housing 200 and covers the outside of the PCB board 300 to adjust the irradiation range of the vehicle lamp through the lens 400. The decorative frame 500 and the lamp cover 600 cover the outside of the lens 400 and are detachably connected to the lamp housing 200 to protect the lens 400 inside the vehicle lamp. The radiator 100 is connected to the side of the lamp housing 200 away from the PCB board 300, and the radiator 100 is in contact with the PCB board 300 to dissipate the heat generated by the PCB board 300.

[0060] It should be noted that the lamp housing assembly is the lamp housing assembly disclosed in the above embodiment. Therefore, the vehicle lamp with this lamp housing assembly also has all the technical effects, which will not be elaborated one by one here.

[0061] In addition, this application also discloses a vehicle, including a vehicle lamp. Among them, the vehicle lamp assembly is the vehicle lamp disclosed in the above embodiment. Therefore, the vehicle with this vehicle lamp also has all the above technical effects, which will not be elaborated here.

[0062] In this specification, the various embodiments are described in a progressive manner. The key point of each embodiment is to explain the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.
