Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting heat dissipation technology, and in particular to a heat dissipation component and vehicle lighting device. Background Technology

[0002] Automotive headlight components, such as circuit boards and LED chips, generate considerable heat during use. If this heat cannot be dissipated effectively, it will severely impact the headlight's performance and lifespan. However, existing headlights suffer from the following drawbacks: they lack a proper heat dissipation structure or their design is flawed, resulting in poor heat dissipation. Furthermore, the assembly of existing headlight housings is complex and inefficient. Utility Model Content

[0003] Therefore, it is necessary to provide a heat dissipation component and a vehicle lamp device to address the problem that existing vehicle lamps lack heat dissipation structures or have poorly designed heat dissipation structures, resulting in poor heat dissipation performance.

[0004] A heat dissipation assembly includes: a first heat dissipation housing; a second heat dissipation housing disposed on the first heat dissipation housing, the second heat dissipation housing and the first heat dissipation housing forming a mounting cavity for accommodating a vehicle lamp assembly, the first heat dissipation housing having a heat dissipation opening, the second heat dissipation housing having a heat dissipation opening, the first heat dissipation housing and the second heat dissipation housing forming a heat dissipation opening, the heat dissipation opening communicating with the mounting cavity; and a first connector passing through the first heat dissipation housing and / or the second heat dissipation housing, the first connector being used to lock the first heat dissipation housing and the second heat dissipation housing.

[0005] The first aspect of this application discloses a heat dissipation assembly, in which a mounting cavity is formed by a first heat dissipation housing and a second heat dissipation housing, thereby providing a space for accommodating the vehicle lamp assembly. The design incorporates heat dissipation vents on the first and / or second heat dissipation housings, as well as a heat dissipation vent formed by the enclosed portion of the first and second heat dissipation housings. This design is more rational and can effectively dissipate heat generated by the vehicle lamp assembly from multiple directions. This design ensures that heat can be quickly conducted to the external environment, reducing the operating temperature of the vehicle lamp assembly and preventing malfunctions caused by excessively high lamp temperatures, thus reducing the product's lifespan. A first connector, such as a connecting bolt, passes through the first and second heat dissipation housings for locking, ensuring the stability and reliability of the entire heat dissipation assembly and preventing loosening or damage due to vibration or other external forces. This design reduces the difficulty of assembling the lamp housing and improves assembly efficiency. The separate design of the first and second heat dissipation housings makes assembling the vehicle lamp assembly onto the heat dissipation assembly simpler and more convenient, enhancing its practicality.

[0006] In one embodiment, the first heat dissipation housing and / or the second heat dissipation housing are provided with a first heat dissipation opening and a second heat dissipation opening communicating with the mounting cavity. There are multiple second heat dissipation openings, each distributed on both sides of the first heat dissipation opening. The first and second heat dissipation housings together form the third heat dissipation opening communicating with the mounting cavity. The arrangement of the first, second, and third heat dissipation openings promotes heat dissipation from multiple directions and angles, preventing heat accumulation. This design cleverly arranges multiple heat dissipation openings within a limited space, achieving a balance between product practicality and aesthetic appeal.

[0007] In one embodiment, the mounting cavity includes a first receiving cavity and a second receiving cavity, which are connected. The first receiving cavity is connected to the heat dissipation vent, and the first and second receiving cavities are respectively used to accommodate different components of the vehicle lamp assembly. By using the first and second receiving cavities to accommodate different components of the vehicle lamp assembly, targeted design can be carried out according to the heat generation and heat dissipation requirements of different components, optimizing the heat dissipation effect. The connection between the first and second receiving cavities allows heat from the second receiving cavity to be transferred and dispersed through the first receiving cavity, avoiding localized overheating and improving overall heat dissipation efficiency. Furthermore, it facilitates the connection and wiring between different components of the vehicle lamp assembly.

[0008] In one embodiment, the first heat sink housing has a first mounting hole, and the second heat sink housing has a second mounting hole, which is opposite to the first mounting hole. The first connector passes through the first mounting hole and is fitted into the second mounting hole. The opposite arrangement of the first and second mounting holes ensures that the first connector can pass through accurately, and the assembly of the first and second heat sink housings is easy. This design forms a strong mechanical connection, preventing the first and second heat sink housings from loosening or separating during use.

[0009] In one embodiment, the first heat sink and the second heat sink have identical structures. Because the first and second heat sinks have identical structures, they can be manufactured using the same mold, reducing mold manufacturing costs. Furthermore, the identical structural design provides better visual symmetry and enhances the overall aesthetic appeal.

[0010] In one embodiment, the first heat sink housing includes a mounting post, a decorative shell, and a heat sink. Both the mounting post and the heat sink are disposed on the decorative shell and are located on opposite sides of the decorative shell. The mounting post has a third mounting hole and also includes a second connector. The second connector passes through the third mounting hole and is used to connect to the headlight assembly. The heat sink has the heat dissipation vent, and the heat sink and the second heat sink together form the mounting cavity. The third mounting hole on the mounting post provides precise positioning for the headlight assembly. The second connector strengthens the connection between the first heat sink and the headlight assembly, reducing the risk of loosening or detachment.

[0011] In one embodiment, the mounting post is provided with a first adapter port, or the mounting post and the second heat sink housing enclose each other to form a first adapter port. The first adapter port is located on the side of the mounting post and is used to mate with the headlight assembly. The tight fit between the first adapter port and the headlight assembly effectively increases the fixing points of the first heat sink housing, the second heat sink housing, and the headlight assembly, thereby enhancing the stability of the entire headlight assembly.

[0012] In one embodiment, the mounting post is provided with a second adapter port, or the mounting post and the second heat dissipation housing enclose each other to form a second adapter port. The second adapter port is located at the top of the mounting post and is used to adapt to the vehicle lamp assembly. The second adapter port at the top of the second mounting post allows for adaptation to the lamp body, thereby providing an additional fixing point, enhancing the connection stability between the mounting post and the vehicle lamp assembly, and reducing the risk of loosening due to vibration or external forces.

[0013] In one embodiment, the mounting column, the decorative shell, and the heat dissipation shell are integrally formed. This integrated design eliminates problems caused by loose connections, improving product durability and reliability. Furthermore, the integrated design reduces the amount of additional materials and processes required during assembly, thereby lowering production costs.

[0014] In one embodiment, the heat dissipation shell includes a first shell and a second shell. The first shell is disposed on the decorative shell and has a first receiving cavity. The first shell also has a first heat dissipation opening and a second heat dissipation opening communicating with the first receiving cavity. There are two second heat dissipation openings distributed on both sides of the first heat dissipation opening. The second shell is disposed on the first shell at the end of the first shell furthest from the decorative shell and has a second receiving cavity communicating with the first receiving cavity. The second receiving cavity is connected to the first heat dissipation opening. The first and second shells, each with a first receiving cavity and a second receiving cavity respectively, connected by the first heat dissipation opening, form an effective heat dissipation channel, enhancing the heat dissipation effect. The two second heat dissipation openings distributed on both sides of the first heat dissipation opening help dissipate heat from multiple directions, thereby achieving balanced heat dissipation, avoiding localized overheating, and improving overall heat dissipation uniformity.

[0015] In one embodiment, the first heat sink housing has a first opening, and the second heat sink housing has a second opening. The first opening and the second opening are arranged opposite to each other and both communicate with the second receiving cavity. The arrangement of the first and second openings allows the lamp beads of the vehicle lamp assembly to emit light from both sides when installed in the second receiving cavity. Furthermore, heat within the second receiving cavity can be dissipated through the first and second openings, increasing the heat dissipation effect.

[0016] In one embodiment, the second heat sink housing is provided with a fourth mounting hole, which is located at both ends of the second heat sink housing, along with the second mounting hole. It also includes a third connector that passes through the fourth mounting hole and is used to connect to the vehicle light assembly. The fact that the fourth and third mounting holes are located at opposite ends of the second heat sink housing provides the possibility of multiple fixing points, enhancing the connection stability between the heat sink housing and the vehicle light assembly.

[0017] A vehicle lighting device includes: the aforementioned heat dissipation assembly; and a vehicle lighting assembly disposed on the heat dissipation assembly, wherein the vehicle lighting assembly is at least partially located within the mounting cavity, and the heat dissipation assembly is used for heat dissipation of the vehicle lighting assembly.

[0018] The second aspect of this application discloses a vehicle lighting device in which the vehicle lighting assembly is mounted on a heat dissipation assembly. The heat dissipation assembly can quickly dissipate heat from the vehicle lighting assembly, preventing overheating and thus extending its service life and improving performance stability. This design ensures stable operation of the vehicle lighting assembly under various operating conditions, meeting relevant safety and performance standards.

[0019] In one embodiment, the vehicle lamp assembly includes a lamp base, a circuit board, and an LED assembly. The heat dissipation assembly has a first receiving cavity and a second receiving cavity. The lamp base is disposed on the heat dissipation assembly and located at its end. The circuit board is disposed on the heat dissipation assembly and / or the lamp base, located within the first receiving cavity. The LED assembly is disposed on the heat dissipation assembly and located within the second receiving cavity. By placing the circuit board within the first receiving cavity, which communicates with the maximum number of heat dissipation vents, rapid heat dissipation is ensured, reducing the operating temperature of the circuit board. By placing the LED assembly within the second receiving cavity, the light emitted by the LED assembly can be emitted from both sides of the heat dissipation assembly to achieve illumination, improving practicality.
