[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1 and Figure 2As shown, a heat dissipation structure of a vehicle lamp module includes an air supply component 10, a first heat dissipation component 2A and a second heat dissipation component 2B. The first heat dissipation component 2A and the second heat dissipation component 2B are respectively arranged on the first vehicle lamp module 3A and the second vehicle lamp module 3B. The air supply component 10 is arranged on the vehicle lamp housing, and includes a fan 11 and an air guide cover 12. The fan 11 is arranged on the air guide cover 12, that is, it is installed on the lower end of the air guide cover 12 by means of a snap, a locking structure, etc. A drainage cavity 100 is formed at the connection between the air guide cover 12 and the fan 11, and a pair of first exhaust cavities 101 and second exhaust cavities 102 respectively connected to the drainage cavity 100 are provided on the air guide cover 12. The ends of the first exhaust cavity 101 and the second exhaust cavity 102 respectively point to the first heat dissipation component 2A and the second heat dissipation component 2B, a pair of first air guide plates 121 are formed in the first exhaust cavity 101, and a pair of second air guide plates 122 are formed in the second exhaust cavity 102.

[0027] In the present invention, a first headlight module 3A and a second headlight module 3B are provided in a headlight housing (not shown) for different lighting forms. For this purpose, a first heat dissipation assembly 2A and a second heat dissipation assembly 2B are provided for heat dissipation of the first headlight module 3A and the second headlight module 3B, respectively, to avoid high temperature of the light source assembly in each headlight module, thereby increasing the service life of the light source assembly (heat conduction and heat dissipation can be achieved through the contact between the heat dissipation assembly and the control board in the light source assembly), and the blowing action of the fan 11 continuously transports the flowing air through the first exhaust cavity 101 and the second exhaust cavity 102 to the first heat dissipation assembly 2A and the second heat dissipation assembly 2B, thereby accelerating the air flow at the first heat dissipation assembly 2A and the second heat dissipation assembly 2B, and continuously taking away the heat on the first heat dissipation assembly 2A and the second heat dissipation assembly 2B through the flowing air, thereby facilitating the light source assembly to continuously conduct the generated heat to the heat dissipation assembly, which can effectively reduce the temperature of the first headlight module 3A and the second headlight module 3B.

[0028] The utility model can divert the transported flowing air through the action of the fan 11 and the first exhaust cavity 101 and the second exhaust cavity 102 on the air guide cover 12, and effectively transport the flowing air to different headlight modules for cooling, thereby improving the service life of the headlight modules; in addition, by respectively arranging a pair of first air guide plates 121 and a pair of second air guide plates 122 in the first exhaust cavity 101 and the second exhaust cavity 102, the flowing air can be transported more concentratedly, so that the outlet position and the outlet form of the flowing air are more consistent with the position and structure of the heat dissipation component, and the concentrated flowing air has a higher flow rate, so that the heat dissipation component is exposed to a larger amount of flowing air, thereby having a more efficient heat dissipation effect.

[0029] Continue as Figure 2As shown, the first air guide plate 121 and the second air guide plate 122 both have a bending structure, which can guide the flowing air more smoothly. The gap between a pair of first air guide plates 121 on the side close to the drainage cavity 100 is larger than the gap on the side away from the drainage cavity 100, and the gap between a pair of second air guide plates 122 on the side close to the drainage cavity 100 is larger than the gap on the side away from the drainage cavity 100. The above-mentioned arrangement can form a relatively narrow flowing air outlet on the side of the air guide plate away from the drainage cavity 100 (the flowing air outlet can cover the range of the adjacent side of the heat dissipation component), where a larger air outlet pressure and flowing air outlet volume can be formed, which is conducive to accelerating air flow for rapid heat dissipation.

[0030] Furthermore, the ends of the first air guide plate 121 and the second air guide plate 122 extend into the drainage cavity 100, which can more effectively guide the flowing air generated by the fan 11, avoid the flowing air from diverging, and improve the utilization efficiency of the flowing air.

[0031] The first air guide plate 121, the second air guide plate 122 and the air guide cover 12 are an integrally formed structure. There is a gap between the first air guide plate 121 and the inner wall of the first exhaust cavity 101, and between the second air guide plate 122 and the inner wall of the second exhaust cavity 102. Since the air guide cover 12 also has the function of being installed in the car lamp housing, that is, the air guide cover 12 needs to be locked to the car lamp housing through the side walls of the first exhaust cavity 101 and the second exhaust cavity 102, the size and shape of the air guide cover 12 need to be coordinated with the structure of the car lamp housing. It should not be too small, but the delivery volume and delivery path of the flowing air need to be taken into consideration. Therefore, a gap structure is required between the side wall of the exhaust cavity and the air guide plate to meet the above requirements.

[0032] like Figure 3 and Figure 4 As shown, the first heat dissipation component 2A includes at least a heat dissipation plate 21, the heat dissipation plate 21 includes a connecting plate 211, and a plurality of heat dissipation fins 212 arranged on the connecting plate 211, the connecting plate 211 is arranged on the heating element of the first headlight module 3A (such as the control board 31 in the light source assembly), the first exhaust cavity 101, and a pair of first air guide plates 121 on the side away from the drainage cavity 100 are closely aligned with the heat dissipation fins 212, the connecting plate 211 has a large contact area and heat conduction area, and the contact between the plurality of heat dissipation fins 212 and the connecting plate 211 can be more conducive to heat dissipation, and the heat on the heat dissipation fins 212 can be quickly taken away by the flowing air entering the gaps between the heat dissipation fins 212 to improve the heat dissipation efficiency.

[0033] Specifically, a card slot 2102 is provided on the connecting plate 211, and the card slot 2102 is connected to the buckle 321 on the first headlight module 3A to preliminarily position the heat sink 21 on the first headlight module 3A; further, a first locking hole 2101 is provided on the connecting plate 211, and the connecting plate 211 is locked on the heating element by a bolt passing through the first locking hole 2101, which can ensure the connection stability between the heat sink 21 and the heating element; further, a second locking hole 2103 is provided on the connecting plate 211, and the connecting plate 211 is locked on the first headlight module 3A by a bolt passing through the second locking hole 2103, which ensures the installation stability of the connecting plate 211 and the headlight module.

[0034] Preferably, the first heat dissipation assembly 2A also includes a seal 22, which includes a cover plate 221. An opening 220 is provided in the middle of the cover plate 221, and a plurality of hooks 222 are provided on its side wall. The hooks 222 are connected to the block 322 on the first headlight module 3A so that the cover plate 221 is wrapped around the edge of the connecting plate 211, and the heat dissipation fins 212 extend out of the opening 220. Since the flowing air is transported quickly and in large quantities by the fan 11, in order to prevent foreign matter (such as dust, etc.) from entering the first headlight module 3A through the gap at the heating element during the contact between the flowing air and the heat sink 21, a seal 22 is provided to wrap the connecting plate 211 and the gap at the connection between the connecting plate 211, the heating element and the first headlight module 3A. The cooperation between the hook 222 and the block 322 can position the seal 22 on the first headlight module 3A, and the opening 220 allows the heat dissipation fins 212 to extend and contact with the flowing air delivered by the air supply assembly 10 without affecting the heat dissipation efficiency.

[0035] Furthermore, a plurality of cover plates 223 are provided on the side of the cover plate 221 , and the plurality of cover plates 223 are respectively engaged with the bolts and buckles used to connect the heat dissipation plate 21 and the first lamp module 21 , which can further improve the sealing of the connection.

[0036] In addition, similarly, the second heat dissipation assembly 2B and the second headlight module 3B can have the same structure and form as the first heat dissipation assembly 2A and the first headlight module 3A.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
