Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle lights, and in particular to a motorcycle headlight structure. Background Technology

[0002] To facilitate nighttime driving, existing motorcycles and electric bicycles are equipped with headlights, and the installation standards require that the headlights have both high beam and low beam functions.

[0003] Existing motorcycle headlight structures generally include several major parts such as the lamp housing, lighting structure, reflector, and lens. The lighting structure usually consists of a light source board with two sets of LED beads for high beam and low beam functions. In order to improve luminous flux, modern headlights use high-power LED beads, which results in high heat generation. Prolonged high-temperature operation can affect the LED lighting effect and lifespan. Therefore, existing lighting structures are equipped with large heat sinks to assist in heat dissipation. However, this heat dissipation effect is not good, and it also makes the overall size of the lighting structure too large. Utility Model Content

[0004] The present invention provides a motorcycle headlight structure that reduces the size of the lighting structure while ensuring heat dissipation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motorcycle headlight structure, comprising an aluminum lamp body, a lamp head, and a light source module. One end of the aluminum lamp body is connected to the lamp head, and the other end is provided with a heat sink. A mounting plate is provided in the middle of the aluminum lamp body, and the light source module is disposed on one side of the mounting plate. The mounting plate has a through hole. High beam and low beam light sources are respectively provided on both sides of the light source module. The low beam light source is disposed in the through hole. The heat sink has an air duct cavity, and a cooling fan and cooling fins are disposed in the air duct cavity. The cooling fins are disposed between the cooling fan and the light source module. The mounting plate has a recessed insertion groove, and the light source module is disposed in the insertion groove. The through hole is located at the bottom of the insertion groove.

[0006] Furthermore, the end face of the heat sink is provided with a first heat dissipation tooth pattern.

[0007] Furthermore, the heat sink has a heat dissipation channel on its sidewall along the thickness direction, and the inner sidewall of the heat dissipation channel has a second heat dissipation tooth pattern.

[0008] Furthermore, both the high beam and low beam light sources include a copper substrate and LED chips.

[0009] Furthermore, a power module is provided inside the lamp head, and the power module is connected to the high beam light source and the low beam light source respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by setting high beam light source and low beam light source on both sides of the light source module respectively, and the low beam light source is correspondingly set in the through hole of the mounting plate, the cooling fan and cooling fins in the heat dissipation head air duct cavity are used to dissipate heat for the light source module, thereby improving the heat dissipation effect of the high beam light source and the low beam light source, and thus extending the service life of the vehicle light.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] As attached Figure 1-3As shown, this utility model discloses a motorcycle headlight structure, including an aluminum lamp body 10, a lamp head 20, and a light source module 30. One end of the aluminum lamp body 10 is connected to the lamp head 20, and the other end is provided with a heat sink 101. A mounting plate portion 102 is provided in the middle of the aluminum lamp body 10. The light source module 30 is disposed on one side of the mounting plate portion 102. The mounting plate portion 102 has a through hole 1021. High beam light sources 31 and low beam light sources 32 are respectively provided on both sides of the light source module 30. The low beam light source 32 is disposed within the through hole 1021. The heat sink 101 has an air duct cavity 1011, within which a cooling fan 40 and cooling fins 50 are disposed. The heat dissipation fins 50 are disposed between the cooling fan 40 and the light source module 30. The mounting plate portion 102 has a recessed insertion groove 103, and the light source module 30 is disposed in the insertion groove 103. The through hole 1021 is located at the bottom of the insertion groove 103. It should be understood that by providing a high beam light source 31 and a low beam light source 32 on both sides of the light source module 30, and the low beam light source 32 is correspondingly disposed in the through hole 1021 of the mounting plate portion 102, the cooling fan 40 and the heat dissipation fins 50 in the air duct cavity 1011 of the heat dissipation head 101 dissipate heat for the light source module 30, thereby improving the heat dissipation effect of the high beam light source 31 and the low beam light source 32, and thus extending the service life of the vehicle lights.

[0017] In this embodiment, the end face of the heat sink 101 is provided with a first heat dissipation tooth pattern 1012, and the side wall of the heat sink 101 is provided with a heat dissipation channel 1013 along the thickness direction. The inner side wall of the heat dissipation channel 1013 is provided with a second heat dissipation tooth pattern 1014. The first heat dissipation tooth pattern 1012 and the second heat dissipation tooth pattern 1014 can further increase the contact area between the heat sink 101 and the outside world, thereby improving the heat dissipation effect.

[0018] In this embodiment, both the high beam light source 31 and the low beam light source 32 include a copper substrate and LED chips; wherein the LED chips are soldered onto the copper substrate by SMT surface mount technology.

[0019] In this embodiment, a power module 60 is provided inside the lamp head 20. The power module 60 is connected to the high beam light source 31 and the low beam light source 32 respectively. The power module 60 is an existing structure. Existing motorcycle lamps also include a lamp housing, and a reflector is provided inside the lamp housing. This is also an existing motorcycle lamp structure. It should be noted that neither the high beam light source 31 nor the low beam light source 32 shines directly forward. After they are lit, they shine on the reflector and the light source is refracted forward by the refraction principle of the reflector.

[0020] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
