Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of backlight, especially to a high-brightness backlight source of electric vehicle. BACKGROUND

[0002] The in-vehicle backlight source refers to a light emitting device installed in the interior of an automobile for providing auxiliary lighting or creating an atmosphere. It is usually installed in positions such as the roof, doors, center console, and under the seat, and improves the comfort, aesthetics, or functionality of the interior of the vehicle through light effects. The in-vehicle backlight source has become an important element of modern automotive interior design, which not only improves the driving experience, but also becomes a key to brand differentiation. Whether it is a factory configuration or a post-market modification, safety, compatibility, and personal needs should be considered when choosing.

[0003] However, the traditional high-brightness backlight source of electric vehicles needs to install high-power LED chips on the backlight source to achieve the required brightness during use, so the backlight source usually generates a large amount of heat. If the heat is not dissipated in time, it may cause the performance of the light source to decrease, the service life to be shortened, and even safety hazards to be caused.

[0004] For example, the traditional high-brightness backlight source of electric vehicles usually designs on an aluminum substrate to achieve the heat dissipation effect during use, which may cause the mechanism redundancy of the aluminum substrate and the heat dissipation effect is not good enough, which may have multiple negative impacts on the performance, safety, service life, and user experience of the vehicle. UTILITY MODEL CONTENT

[0005] The utility model discloses a high-brightness backlight source of electric vehicle, which aims to solve the technical problem that the traditional high-brightness backlight source of electric vehicles needs to install high-power LED chips on the backlight source to achieve the required brightness during use, so the backlight source usually generates a large amount of heat. If the heat is not dissipated in time, it may cause the performance of the light source to decrease, the service life to be shortened, and even safety hazards to be caused.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

The other end of the six heat pipes is connected with the outer wall of the bottom of the aluminum substrate.

[0009] The quick release mechanism is arranged on the aluminum substrate.

[0010] In the scheme, the micro heat dissipation fins arranged on the outer wall of the bottom of the aluminum substrate increase the heat dissipation area to accelerate heat diffusion, and the micro heat dissipation fins cooperate with the heat pipes inside to make one end of the heat pipes connected with the outer wall of the bottom of the aluminum substrate, so that the heat generated by the backlight during operation is transmitted to the heat pipes, the heat pipes quickly transmit the heat of the heat source to the heat dissipation fins, and the fins dissipate the heat to the environment through natural convection, forced convection and radiation, which not only effectively dissipates heat, but also makes the temperature distribution of the heat source more uniform, avoiding local overheating.

[0011] In a preferred scheme, the inside of the iron frame is also a hollow structure, and circular holes are arranged on the top outer wall of the iron frame in an equidistant distribution.

[0012] By arranging the iron frame as a hollow structure and the circular holes in an equidistant distribution on the top outer wall of the iron frame, the edge of the backlight is arranged as an annular heat dissipation channel, which can quickly guide out heat by air convection to speed up heat dissipation.

[0013] In a preferred scheme, a clamping groove is arranged on the inner wall of the opposite side of the placing groove, a spring is arranged in the inside of the two clamping grooves, and a spring block is connected to one side of the two springs, and the LED light bar is arranged in the inside of the two spring blocks.

[0014] By arranging the placing grooves in an equidistant distribution on the top outer wall of the aluminum substrate and the springs and spring blocks arranged on the inner walls of the two sides of the placing grooves, the LED light bar can be clamped into the inside of the placing grooves during installation, so that the two spring blocks are compressed into the inside of the clamping grooves through the springs, and the LED light bar is fixed by the elastic force of the springs and spring blocks, and when part of the LED light bar is damaged, the LED light bar can be clamped and taken out, supporting quick replacement of damaged modules and reducing maintenance cost.

[0015] As can be seen from the above, the high-brightness backlight source for electric vehicles comprises a light guide plate and an iron frame arranged on the outer wall of the light guide plate, and further comprises: a heat dissipation mechanism, the heat dissipation mechanism comprising an aluminum substrate arranged on the outer wall of the bottom of the iron frame, two rows of micro heat dissipation fins arranged in an equidistant distribution on the outer wall of the bottom of the aluminum substrate, three heat pipes arranged in the inside of the two rows of micro heat dissipation fins respectively, and the other end of the six heat pipes connected with the outer wall of the bottom of the aluminum substrate; and a quick release mechanism arranged on the aluminum substrate.
