Technical Field
[0001] The utility model belongs to the technical field of headlamp accessories and relates to a high waterproof and heat dissipation air duct structure for an electric vehicle headlamp. Background Technique
[0002] The LED light source is a green light source with high efficiency, long life, adjustable color temperature, small volume and strong earthquake resistance. Based on the above advantages, it has been used as the headlamp light source of electric vehicles. In the electric vehicle headlamp, a corresponding heat dissipation system needs to be set up to ensure the heat dissipation effect of the electric vehicle headlamp (that is, the LED light source) and ensure that the LED light source can carry out lighting operations for a long time.
[0003] In the prior art, in order to dissipate heat better, heat dissipation holes are mostly opened. The heat dissipation holes found at the back of the headlamp are usually covered by a plastic cover and a rubber sleeve. The defect of the existing method is that heat cannot be dissipated quickly and efficiently and the waterproof effect is not good. Based on this, we design a high waterproof and heat dissipation air duct structure for an electric vehicle headlamp. Summary of the Invention

[0006] The hot air duct assembly includes a diversion cover connection end, a first aluminum alloy air guide section, a second aluminum alloy air guide section and two hot air outlet cylinders. One end of the first aluminum alloy air guide section and one end of the second aluminum alloy air guide section are both communicated with the middle of the hot air diversion cover through the diversion cover connection end, and the other end of the first aluminum alloy air guide section and the other end of the second aluminum alloy air guide section are respectively communicated with the two hot air outlet cylinders;
[0007] Rubber tail sleeves are arranged at the tails of the two hot air outlet cylinders. Air outlet openings are arranged at the tails of the two rubber tail sleeves. Ring-shaped shape memory alloys are arranged inside the two rubber tail sleeves. Electrode connection seats are arranged on the sides of the two ring-shaped shape memory alloys, and wires are connected to the terminals of the electrode connection seats.
[0008] In the above-mentioned high waterproof and heat dissipation air duct structure of the electric vehicle headlight, a heat dissipation component is further included. The heat dissipation component is composed of a fin base and two heat dissipation fins. The two heat dissipation fins are embedded at two grooves of the fin base. A circular perforation is provided at the center of the two heat dissipation fins. The two heat dissipation fins are connected to the first aluminum alloy air guiding section and the second aluminum alloy air guiding section through the circular perforations. The purpose of such a setting is to increase the heat dissipation effect of the first aluminum alloy air guiding section and the second aluminum alloy air guiding section itself, so that the heat in the hot air guided by the first aluminum alloy air guiding section and the second aluminum alloy air guiding section can be quickly dissipated to the outside.
[0009] In the above-mentioned high waterproof and heat dissipation air duct structure of the electric vehicle headlight, a limiting frame is provided in the middle of the first aluminum alloy air guiding section and the middle of the second aluminum alloy air guiding section. Limiting grooves corresponding to the limiting frames are provided on the surfaces of the two heat dissipation fins. The purpose of such a setting is to improve the firmness and stability of the connection between the first aluminum alloy air guiding section, the second aluminum alloy air guiding section and the heat dissipation component, and avoid the phenomenon of poor contact caused by loosening.
[0010] In the above-mentioned high waterproof and heat dissipation air duct structure of the electric vehicle headlight, an integrally formed isolation tape is provided in the middle of the fin base. The planar thickness of the heat dissipation fin is smaller than the planar thickness of the isolation tape. The purpose of such a setting is to be able to isolate the two heat dissipation fins, so that the heat of the two heat dissipation fins does not interfere with each other.
[0011] In the above-mentioned high waterproof and heat dissipation air duct structure of the electric vehicle headlight, mounting frames are provided at the centers of the two annular shape memory alloys. The annular shape memory alloys are connected to the hot air outlet cylinder through the mounting frames. The purpose of such a setting is to have a good effect of positioning the positions of the annular shape memory alloys, so that the annular shape memory alloys are in a stable state.
[0012] In the above-mentioned high waterproof and heat dissipation air duct structure of the electric vehicle headlight, the maximum opening diameter of the air outlet opening is three-halves of the initial diameter of the air outlet opening. The purpose of such a setting is to facilitate expanding the opening degree of the air outlet opening and facilitate the rapid discharge of hot air.
