Description

Technical Field

[0001] This utility model belongs to the technical field of automotive headlight radiators, specifically relating to a platform-based automotive headlight radiator. Background Technology

[0002] In recent years, the new energy vehicle market has been booming. Under the influence of new energy vehicles, multi-functional, multi-zone, and multi-light-emitting signal light groups have sprung up everywhere. This has brought unprecedented challenges to the vehicle light heat dissipation system. In order to meet the heat dissipation requirements of high-power signal lights, radiators are often used on the lights. Traditional radiator processing technology mostly adopts die casting, stamping, and cold extrusion solutions.

[0003] Current automotive headlight designs are trending towards flatter and smaller shapes, and the development of front trunks in new energy vehicles has further compressed the space in the engine compartment. Traditional radiators, designed to meet the cooling needs of diverse high-power signal light assemblies, often require larger heat dissipation areas and volumes, which contradicts the need for miniaturized headlights. Furthermore, traditional radiators require custom-designed headlight radiators tailored to specific projects. Developing a new headlight necessitates the creation of entirely new tooling, molds, and other equipment to match the radiator, significantly increasing the cost of headlight development. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing automotive headlight radiators being large in size and requiring "one-to-one" custom development, resulting in high costs. This invention designs a platform-based automotive headlight radiator that can flexibly adjust the relevant parameters of the radiator to meet the varying requirements of different vehicle models for heat dissipation area and volume, while also being adaptable to the irregular spaces in the front engine compartment of different vehicle models.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a platform-based automotive headlight radiator, comprising a housing, a PCB assembly, and a radiator body. The radiator body is mounted on the housing, and one side of the radiator body is connected to the PCB assembly, while the other side is connected to several heat dissipation columns. The heat dissipation columns are detachably connected to the side of the radiator body away from the housing, and the length of the heat dissipation columns is adjustable.

[0006] Preferably, the housing is provided with a plurality of first screw post structures at intervals along its circumference, and the heat sink body has first mounting holes corresponding to the first screw post structures, and the first mounting holes are fixed to the first screw post structures by first self-tapping screws.

[0007] Preferably, a sealing ring is provided between the housing and the radiator body, and a first mating structure and a second mating structure are respectively provided on the housing and the radiator body to cooperate with the sealing ring.

[0008] Preferably, the PCB assembly has a second mounting hole corresponding to the second screw post structure on the heat sink body, and the second mounting hole and the second screw post structure are fixedly connected by a second self-tapping screw.

[0009] Preferably, the PCB assembly and the heat sink body also have corresponding main positioning holes and main positioning posts, as well as auxiliary positioning holes and auxiliary positioning posts.

[0010] Preferably, the radiator body has several connecting structures that cooperate with several heat dissipation columns. One end of each heat dissipation column has a threaded section for detachable connection with the connecting structure, and the other end has an internal hex head that cooperates with a screwdriver.

[0011] Preferably, the heat dissipation column includes heat dissipation columns of various specifications with a length of 5-50mm.

[0012] After adopting the above technical solution, the platform-based automotive headlight radiator provided by this utility model has the following beneficial effects:

[0013] (1) This utility model, through the design of detachable heat dissipation column and adjustable heat dissipation column length, can flexibly adapt to the space requirements of the front engine compartment of different models, meet the heat dissipation requirements of different signal lights, effectively reduce the development difficulty in the design stage, and improve the utilization rate of the vehicle engine compartment space.

[0014] (2) This utility model can flexibly adjust the heat dissipation area according to the actual results obtained from the OTS stage test, reduce excessive design redundancy, and save development costs.

Detailed Implementation

[0025] The present invention will now be described in further clear and complete detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0029] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.

[0030] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0031] This utility model discloses a platform-based radiator for automotive headlights, such as... Figure 1-8 As shown, the device includes a housing 1, a PCB assembly 3, and a heat sink body 6.

The heat sink body 6 has first mounting holes 6-5 corresponding to the first screw post structures 1-1, and the first mounting holes 6-5 are fixed to the first screw post structures 1-1 by first self-tapping screws 5. To ensure the sealing effect between the housing 1 and the heat sink body 6, a sealing ring 4 is also provided between the housing 1 and the heat sink body 6. The housing 1 and the heat sink body 6 are respectively provided with a first mating structure 1-2 and a second mating structure 6-4 that are installed in conjunction with the sealing ring 4.

[0032] The PCB assembly 3 is installed on the side of the heat sink body 6 near the housing 1.

[0033] The heat dissipation column 7 is detachably connected to the side of the radiator body 6 away from the housing 1. Specifically, the radiator body 6 has several connecting structures 6-6 that cooperate with the heat dissipation columns 7. One end of the heat dissipation column 7 has a threaded section 7-1 for detachable connection with the connecting structure 6-6, and the other end has an internal hex head 7-2 that cooperates with a screwdriver. During the connection process, a hex screwdriver can be used to assist in the connection through the internal hex head 7-2. Furthermore, in order to adapt to different vehicle space, the length of the heat dissipation column 7 is adjustable. Specifically, the heat dissipation column 7 includes various specifications of heat dissipation columns with lengths of 5-50mm, and the appropriate length of heat dissipation column can be selected according to actual needs.

[0034] When assembling a platform-based automotive headlight radiator according to this utility model, firstly, the PCB assembly 3 is assembled with the main positioning hole 3-2 and the auxiliary positioning hole 3-3 corresponding to the main positioning post 6-2 and the auxiliary positioning post 6-3, and then secured with the second self-tapping screw 2. Next, the sealing ring 4 is assembled to the radiator body 6. Then, the heat sinks 7 of different sizes are connected by the connecting structure 6-6 on the radiator body 6 and the threaded section 7-1 on the heat sink 7. Finally, the first self-tapping screw 5 is used to secure the radiator body 6 to the first screw post structure 1-1 on the housing 1 to complete the installation.

[0035] In summary, the platform-based automotive headlight radiator provided by this utility model allows for flexible control of the radiator's size and heat dissipation area by using heat dissipation columns of different sizes, effectively achieving localized clearance and reducing design and development difficulty. Furthermore, the heat dissipation area can be flexibly adjusted based on actual results obtained from OTS (On-the-Spot) testing, reducing excessive design redundancy and saving development costs. Finally, by using this flexibly adjustable heat dissipation column method, platform-based development of the radiator can be achieved, avoiding the need for traditional "one-to-one" dedicated development for different projects, thereby reducing headlight development costs and timelines and improving radiator utilization.
