[0002] As the automotive industry grows and develops, headlights, as functional and styling parts of vehicles, play an increasingly important role in the competitiveness of the entire vehicle. In the future, headlights will develop towards a trend of more beautiful shapes, higher performance, and richer functions. With the improvement of headlight performance and power, the heat dissipation problem of headlights has become a major obstacle to product evolution.

[0003] The current full-load power of headlights is as high as 50W, and can even reach more than 60W. However, due to the closed space inside the lamp, the air temperature inside the lamp cannot form exchange convection with the outside world, and the heat dissipation efficiency is low, which can easily cause the ambient temperature inside the lamp to rise sharply and burn out the light emitter. Therefore, in most usage scenarios, the light output of the headlight has to be reduced, sacrificing the performance of the headlight to ensure the reliability of the headlight.

[0004] Therefore, a feasible solution is urgently needed to improve the heat dissipation efficiency of the headlights while taking into account the requirements of headlight performance and reliability. Summary of the invention

[0086] As described in the background technology section, the current full-load power of car lamp light sources is as high as 50W, and can even reach more than 60W. However, due to the limitations of the closed space inside the lamp, the air temperature inside the lamp cannot form exchange convection with the outside world, and the heat dissipation efficiency is low, which can easily cause the ambient temperature inside the lamp to rise sharply and burn out the light-emitting body. As a result, in most usage scenarios, it is necessary to reduce the luminous power of the car lamp and sacrifice the performance of the car lamp to ensure the reliability of the car lamp.

[0087] For details, please refer to Figure 1 , Figure 1 A cross-sectional schematic diagram of a heat dissipation system provided in an embodiment of the present application.

[0088] like Figure 1 As shown, the heat dissipation system includes a lampshade, a lamp assembly, a lamp housing and a heat dissipation component. The heat dissipation component is arranged inside the lamp housing, and the heat dissipation efficiency is low. It is necessary to reduce the luminous power of the lamp and sacrifice the performance of the lamp to ensure the reliability of the lamp.

[0089] In view of this, the present application provides a connector, a heat dissipation device, a heat dissipation system and a movable terminal, which relate to the field of heat dissipation technology and can be specifically applied to vehicle lights to improve the heat dissipation efficiency of the vehicle lights while taking into account the performance and reliability requirements of the vehicle lights.

[0096] Among them, the connecting member 30 is provided with a mounting hole, and the mounting hole passes through the connecting member 30 along the thickness direction of the connecting member 30. It can be understood that the position of the mounting hole can be used to place the heat dissipation component 40. The heat dissipation component 40 is arranged on the outside of the lamp housing 20 through the mounting hole, and the heat dissipation component 40 can be externalized to improve the heat dissipation efficiency of the car lamp.

[0098] The heat dissipation components of current headlights are usually arranged on the inside of the lamp housing. Due to the limitations of the closed space inside the lamp, the air temperature inside the lamp cannot form exchange convection with the outside world, and the heat dissipation efficiency is low, which can easily cause the ambient temperature inside the lamp to rise sharply and burn out the light-emitting body. As a result, in most usage scenarios, the reliability of the headlight has to be ensured by reducing the luminous power of the headlight and sacrificing the performance of the headlight.

[0100] It is understandable that, since the improvement of the heat dissipation system in the embodiment of the present application mainly lies in the structural form of the connector 30 and the connection method of the connector 30 with the lamp housing 20 and / or the heat dissipation component 40, the heat dissipation system in the embodiment of the present application should at least include the above-mentioned lamp housing 20, the connector 30, and the heat dissipation component 40. Optionally, the heat dissipation system may also include a lampshade 10 and / or a lamp assembly 50.

[0106] It is understandable that the position of the mounting hole 303 can be used to place a heat dissipation component. The heat dissipation component is arranged on the outside of the lamp housing through the mounting hole, so that the heat dissipation component can be externalized to improve the heat dissipation efficiency of the vehicle lamp.

It can be understood that Fig.13 it can also correspond to an enlarged schematic diagram of the dotted area 60 in the heat dissipation system shown above Figure 4 .

[0166] As Fig.13 shown, it can be seen that the heat dissipation component and the component can be integrally formed by two-color or secondary injection molding. For example, the flange of the heat dissipation component can be two-color or secondary injection molded, which can integrate the flexible connection and hermetic connection performance of the heat dissipation component and the component, and can reduce the mold size, reduce the dimming resistance, simplify the assembly, and reduce the cost.

[0167] Optionally, the lamp housing is hermetically connected to the heat dissipation component through a sealing ring. The sealing ring can be made of soft rubber material, which can achieve the hermetic connection between the lamp housing and the heat dissipation component, effectively preventing dust and moisture from invading the internal space of the vehicle lamp and damaging the lamp group and the circuit, thus having a good lighting effect and a long service life.

[0168] Case 3: The component is connected to the first connection groove and / or the second connection groove through a fastener.

[0169] The component to be connected and the connection groove can be fixedly connected through fasteners such as screw threads, pins, and detachable covers.

[0170] Through the embodiment of the present application, the external placement of the heat dissipation component can be realized, the heat dissipation efficiency of the vehicle lamp can be improved, and through the elastic deformation of the connection part and the deformation part of the component, the position adjustment of the lamp group can be realized while ensuring the sealing performance of the vehicle lamp, and then the dimming function of the vehicle lamp can be realized, taking into account the requirements of the performance and reliability of the vehicle lamp.

[0171] The present application provides a heat dissipation device, which is used to connect a heat dissipation component; the heat dissipation device includes a lamp housing and a component as shown above Figures 10 to 13 .

[0172] Among them, the heat dissipation component is located outside the lamp housing, the component is connected to the lamp housing, and the component is integrally formed with the lamp housing.

[0173] Optionally, the lamp housing and the connector can be integrally formed by single-color injection molding. By partially thinning the connector, the connector can achieve flexible connection and sealed connection performance, and the manufacturing and assembly are simple, the cost is low, and the space occupied is small.

[0174] Optionally, the lamp housing and the connecting parts can be molded in one piece by two-color or secondary injection molding. For example, the inside of the lamp housing is made of hard rubber material and the outside of the lamp housing is made of soft rubber material. The flexible connection and sealed connection between the connecting parts and the lamp housing can also be achieved, and the opening size of the lamp housing can be greatly reduced, reducing dimming resistance, simplifying assembly and reducing cost.

[0175] Optionally, the lamp housing is sealed and connected to the heat dissipation component through a sealing ring, which may be made of soft rubber material, so as to achieve a sealed connection between the lamp housing and the heat dissipation component, thereby effectively preventing dust and water vapor from invading the internal space of the lamp and causing damage to the lamp group and the circuit, thereby achieving good lighting effects and a longer service life.

[0176] The heat dissipation components of current headlights are usually arranged on the inside of the lamp housing. Due to the limitations of the closed space inside the lamp, the air temperature inside the lamp cannot form exchange convection with the outside world, and the heat dissipation efficiency is low, which can easily cause the ambient temperature inside the lamp to rise sharply and burn out the light-emitting body. As a result, in most usage scenarios, the reliability of the headlight has to be ensured by reducing the luminous power of the headlight and sacrificing the performance of the headlight.

[0177] In the embodiment of the present application, the heat dissipation component is arranged on the outside of the lamp housing through the mounting hole of the connecting piece, so that the heat dissipation component can be externalized to improve the heat dissipation efficiency of the car lamp, and the flexible connection and sealing connection performance of the connecting piece can be achieved through the elastic deformation of the connecting piece, while ensuring the sealing of the car lamp, the position of the lamp group can be adjusted, thereby realizing the dimming function of the car lamp, taking into account the performance and reliability requirements of the car lamp, and the manufacturing and assembly are simple, the cost is low, and the space occupancy is small.

[0178] The present application provides a heat dissipation device, which is used to connect a lamp housing; the heat dissipation device includes a heat dissipation component and the above Figures 10 to 13 Connectors shown.

[0179] The heat dissipation component is located outside the lamp housing, the connecting piece is connected to the heat dissipation component, and the connecting piece and the heat dissipation component are integrally formed.

[0180] Optionally, the heat dissipation component and the connector can be integrally molded by two-color or two-shot injection molding. For example, the flange of the heat dissipation component can be double-color or two-shot injection molding, which can integrate the flexible connection and sealing connection performance of the heat dissipation component and the connector, and can reduce the mold size, reduce dimming resistance, simplify assembly, and reduce cost.

[0181] Optionally, the lamp housing is sealed and connected to the heat dissipation component through a sealing ring, which may be made of soft rubber material, so as to achieve a sealed connection between the lamp housing and the heat dissipation component, thereby effectively preventing dust and water vapor from invading the internal space of the lamp and causing damage to the lamp group and the circuit, thereby achieving good lighting effects and a longer service life.

[0182] The heat dissipation components of current headlights are usually arranged on the inside of the lamp housing. Due to the limitations of the closed space inside the lamp, the air temperature inside the lamp cannot form exchange convection with the outside world, and the heat dissipation efficiency is low, which can easily cause the ambient temperature inside the lamp to rise sharply and burn out the light-emitting body. As a result, in most usage scenarios, the reliability of the headlight has to be ensured by reducing the luminous power of the headlight and sacrificing the performance of the headlight.

[0183] In the embodiment of the present application, the heat dissipation component is arranged on the outside of the lamp housing through the mounting hole of the connecting piece, so that the heat dissipation component can be externalized to improve the heat dissipation efficiency of the car lamp, and through the elastic deformation of the connecting piece, the flexible connection and sealing connection performance of the connecting piece can be achieved, while ensuring the sealing of the car lamp, the position of the lamp group can be adjusted, and then the dimming function of the car lamp is realized, taking into account the performance and reliability requirements of the car lamp, and the manufacturing and assembly are simple, the cost is low, and the space occupancy is small.
