Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to an integrated housing and vehicle lighting. Background Technology

[0002] With the technological development of the automotive industry, the light source used in vehicle headlights has gradually become dominated by LEDs. LEDs have the characteristics of high brightness and high power, which can provide clearer illumination for vehicle driving. However, LED light sources will generate a lot of heat when working continuously for a long time, which will affect the normal light emission of the LED light source. In order to ensure the normal operation of the headlights, it is usually necessary to install a corresponding heat sink inside the headlights to dissipate the heat generated by the LEDs.

[0003] Currently, when configuring radiators for automotive headlights, it is typically necessary to custom-make mounting brackets to fit the radiator's size, shape, and the internal installation space of the headlight. The radiator is then fixed to the mounting bracket using bolts and other connecting structures, thus achieving the installation and fixation of the radiator inside the headlight. However, the custom production of mounting brackets requires separate mold development and processing, and the procurement of bolts and other connecting structures significantly increases the number of parts in the overall headlight, leading to increased production costs. At the same time, the installation of mounting brackets and bolts within the headlight occupies a considerable amount of space, making it difficult to effectively reduce the overall size of the headlight and meet the development requirements for lightweight and miniaturized automotive headlights. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an integrated housing and vehicle lamp, which aims to solve the technical problem that when configuring a radiator in existing vehicle lamps, it is usually necessary to specially customize a mounting bracket that is compatible with the radiator, and then fix the radiator to the mounting bracket by bolts and other connecting structures. This increases the number of parts in the overall vehicle lamp, resulting in increased production costs. At the same time, it is difficult to effectively reduce the overall size of the vehicle lamp, making it difficult to meet the development needs of lightweight and miniaturized vehicle lamps.

[0005] One aspect of this utility model is to provide an integrated housing, comprising:

[0006] The heat sink includes a base and a plurality of heat sinks extending vertically outward from one side of the base. The plurality of heat sinks are spaced apart along the length direction of the base, and a heat sink groove is formed between two adjacent heat sinks, the heat sink groove extending into the interior of the base.

[0007] The housing body is integrally formed with the heat sink. The housing body includes a first mounting shell and a second mounting shell disposed on one side of the first mounting shell. The first mounting shell is used to mount the lamp cover. The end of the second mounting shell away from the first mounting shell integrally wraps around the circumferential edge of the base and the root of the heat sink.

[0008] The base has an annular groove on its circumferential surface, and the inner wall of the second mounting shell has an annular protrusion that matches the annular groove. The annular protrusion and the annular groove are integrally formed fitting structures.

[0011] Furthermore, at least two first mounting holes are provided at both ends of the base along its length, and a plurality of first mounting holes are spaced apart along the width direction of the base, and the first mounting holes are provided along the thickness direction of the base.

[0012] Furthermore, the base is provided with at least two second mounting holes, which are provided through the base along its thickness direction for the wire harness to pass through.

[0013] Furthermore, positioning posts are provided at both ends of the side of the base away from the heat sink. The positioning posts are integrally formed with the base, and the axial direction of the positioning posts extends along the thickness direction of the base for positioning and cooperation with the PCB board.

[0014] Another aspect of this utility model is to provide a vehicle lamp, which includes a lamp cover, an inner lens, a PCB board, and the aforementioned integrated housing. The lamp cover is sealed to the first mounting housing to form an accommodating space, and the inner lens and the PCB board are located inside the second mounting housing.

[0015] Furthermore, positioning holes are provided on both sides of the PCB board, and the positioning holes are adapted to the positioning posts to realize the positioning and placement of the PCB board on the heat sink.

[0016] Furthermore, connecting posts are provided at both ends of the inner lens along its length, and a connecting through hole is provided on the PCB board for the connecting posts to pass through. The connecting posts are adapted to the first mounting hole to realize the positioning and placement of the inner lens on the heat sink.

[0017] Furthermore, the vehicle light also includes a wiring harness, one end of which passes through the second mounting hole and is electrically connected to the PCB board, and the other end extends to the outside of the integrated housing and is connected to a power interface.

[0018] Furthermore, the vehicle light also includes a vent cap, which is disposed on the side of the first mounting housing opposite to the lamp cover.

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please see Figures 1 to 8 The diagram shows an integrated housing according to the present invention, including a heat sink 10 and a housing body 20. The heat sink 10 includes a base 11 and a plurality of heat sink fins 12 extending vertically outward from one side of the base 11. The plurality of heat sink fins 12 are spaced apart along the length direction of the base 11. In this embodiment, the plurality of heat sink fins 12 are parallel to each other. This layout design can maximize the heat dissipation area and improve the heat dissipation efficiency within a limited space. A heat dissipation groove is formed between two adjacent heat sink fins 12. The heat dissipation groove extends into the interior of the base 11 along the thickness direction of the base 11, so that the heat inside the base 11 can be quickly transferred to the heat sink fins 12 through the heat dissipation groove, and then dissipated through heat exchange between the heat sink fins 12 and the outside air, effectively improving the timeliness and uniformity of heat dissipation.

[0034] Furthermore, in this embodiment, a reinforcing rib 13 is provided between two adjacent heat sinks 12. The reinforcing rib 13 is vertically connected to the heat sink 12. One end of the reinforcing rib 13 is connected to the base 11, and the end face of the other end is flush with the end face of the heat sink 12. The setting of the reinforcing rib 13 can enhance the connection strength between adjacent heat sinks 12, prevent the heat sink 12 from bending or breaking when subjected to external force impact, and thus ensure the normal use of the heat sink 12.

[0035] In some embodiments, the surface of the heat sink 12 is provided with an anodized coating or a heat dissipation coating. The design of the anodized coating can enhance its wear resistance and corrosion resistance, and improve the service life of the heat sink 12; the design of the heat dissipation coating can further reduce thermal resistance, accelerate the conduction and dissipation of heat, and improve the heat dissipation efficiency of the heat sink 12.

[0036] The housing body 20 and the radiator 10 are integrally formed using an insert injection molding process. This design fundamentally eliminates the connection gap between the two, avoiding heat transfer loss caused by assembly gaps and enhancing the thermal conductivity of the overall structure. In actual production, by pre-placing the radiator 10 as an insert in the mold, the integrated housing can be obtained through a single injection molding process. Compared with the traditional multi-process production mode of split structures, this reduces assembly steps, shortens the production cycle, and better meets the needs of large-scale industrial production. Specifically, the housing body 20 includes a first mounting shell 21 and a second mounting shell 22 located on one side of the first mounting shell 21. The first mounting shell 21 is used to mount the lamp cover 31. The end of the second mounting shell 22 away from the first mounting shell 21 integrally wraps around the circumferential edge of the base 11 and the root of the heat sink 12, strengthening the connection between the radiator 10 and the housing body 20. In this embodiment, multiple mounting lugs are provided on both sides of the first mounting shell 21 to install the housing body in a preset mounting position on the vehicle.

[0037] The base 11 has an annular groove 101 on its circumferential surface, and the inner wall of the second mounting shell 22 has an annular protrusion 221 that matches the annular groove 101. The annular protrusion 221 and the annular groove 101 form an integrally molded fitting structure during the insert injection molding process. The two interlock with each other to form a multi-structure limit, which effectively improves the connection between the shell body 20 and the heat sink 10.

[0038] Furthermore, a plurality of connecting blocks 222 are provided at the opening of the second mounting shell 22 away from the first mounting shell 21. The connecting blocks 222 have an L-shaped structure. One end of the connecting block 222 is integrally connected to the inner wall of the second mounting shell 22, and the other end of the connecting block 222 is adapted to the heat dissipation groove and integrally embedded in the heat dissipation groove. The connecting blocks 222 cooperate with the heat dissipation groove formed by the spaced heat dissipation fins 12. When the insert is injection molded, it forms an interlocking fit with the heat sink 10. The relative position of the heat sink 10 and the shell body 20 is doubly limited in both the circumferential and radial directions, which enhances the overall connection strength between the shell and the heat sink 10. At the same time, it increases the contact area between the shell body 20 and the heat sink 10, which is conducive to the transfer of heat from the shell body 20 to the heat sink 10 and improves the overall heat dissipation effect.

[0039] Furthermore, at least two first mounting holes 102 are provided at both ends of the base 11 along its length. Multiple first mounting holes 102 are spaced apart along the width direction of the base 11. The first mounting holes 102 are arranged along the thickness direction of the base 11. The first mounting holes 102 are non-penetrating blind holes. The first mounting holes 102 are used to install the connecting post 331 of the inner lens 33.

[0040] Furthermore, the base 11 is also provided with at least two second mounting holes 103, which are provided through the thickness direction of the base 11 for the wire harness 34 to pass through.

[0041] Furthermore, positioning posts 14 are provided at both ends of the side of the base 11 away from the heat sink 12. The positioning posts 14 are integrally formed with the base 11, and the axial direction of the positioning posts 14 extends along the thickness direction of the base 11 for positioning and cooperating with the PCB board 32.

[0042] In this embodiment, the heat sink 10 is made of high thermal conductivity aluminum or other high thermal conductivity alloy materials to ensure efficient heat dissipation performance; at the same time, the housing body 20 is made of PC+ABS thermoplastic polymer material, which has both good formability and structural strength.

[0043] Another aspect of this utility model is to provide a vehicle lamp, which includes a lamp cover 31, an inner lens 33, a PCB board 32, and the aforementioned integrated housing. The lamp cover 31 is sealed to a first mounting housing 21 to form an accommodating space, and the inner lens 33 and the PCB board 32 are located within a second mounting housing 22. The lamp cover 31 is made of PMMA material, the inner lens 33 is made of PC material, and the vent cap 36 and wiring harness 34 are standard parts to reduce procurement and replacement costs.

[0044] Furthermore, positioning holes are provided on both sides of the PCB board 32, and the positioning holes are adapted to the positioning posts 14 to realize the positioning and placement of the PCB board 32 on the heat sink 10.

[0045] Furthermore, connecting posts 331 are provided at both ends of the inner lens 33 along its length. A connecting through hole is provided on the PCB board 32 for the connecting posts 331 to pass through. The connecting posts 331 are adapted to the first mounting hole 102 to achieve the positioning of the inner lens 33 on the heat sink 10. In practical applications, the connecting posts 331 on the inner lens 33 pass through the connecting through hole 32 on the PCB board and are inserted into the first mounting hole 102 on the base 11, allowing the PCB board 32 and the inner lens 33 to form an integral assembly, which is then fixedly assembled onto the heat sink 10 by laser welding or other welding methods.

[0046] Furthermore, the vehicle light also includes a wiring harness 34, one end of which passes through the second mounting hole 103 and is electrically connected to the PCB board 32, and the other end extends to the outside of the integrated housing and is connected to the power interface 35.

[0047] Furthermore, the headlight also includes a vent cap 36 for balancing the air pressure inside and outside the integrated housing. The vent cap 36 is located on the side of the first mounting housing 21 away from the lamp cover 31.

[0048] Compared with the prior art, the beneficial effects of the integrated housing and vehicle lamp of this utility model are as follows: The integrated housing of this application adopts a design in which the heat sink and the housing body are integrally formed, eliminating the traditional mounting bracket and bolt connection structure, reducing the number of parts, greatly reducing the production cost of the vehicle lamp, and meeting the development needs of lightweight and miniaturized vehicle lamps. At the same time, the integral molding design of the integrated housing, combined with the interlocking structure of the annular protrusion and the annular groove, as well as the interlocking cooperation of the connecting block and the heat dissipation groove, strengthens the connection strength of the overall structure from multiple dimensions, which can improve the structural stability and service life of the integrated housing and vehicle lamp.
