Description

Technical Field

[0001] The utility model relates to the technical field of headlamps, in particular to a headlamp with an anti-fogging function. Background Art

[0002] According to customer requirements, in the design and manufacture of automotive lamps, combined lamps formed by assembling multiple functional lamp modules are the main demand trend, which not only occupy less space but also have diverse functions. In existing combined lamps, they usually include a housing and various lighting function modules installed inside the housing. Currently, the main problem with vehicle lamps is that the shape design of some lamp housings has a shell cavity with one large end and one small end, which are respectively a main cavity area with a large space and an extended cavity area with a small space that is horizontally connected to the main cavity area. After various lighting function modules are installed in the main cavity area and the extended cavity area, due to the narrow space in the extended cavity area, gas is not easily circulated, and the light-emitting components of each module are concentrated in the main cavity area. After the light-emitting components are lit, the air temperature around the light-emitting components rises, and this part of the heat is mainly concentrated in the main cavity area. For the extended cavity area where air cannot flow, the temperature is relatively low, making it easy for fog to form in the inner lens area corresponding to the front and back of the extended cavity area, greatly reducing the lighting effect and thus affecting driving safety. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a headlamp with an anti-fogging function.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A headlamp with an anti-fogging function includes a lamp housing, a first lighting module, an anti-fogging component, and a lamp cover structure. The lamp housing forms a main cavity area and an extended cavity area that is horizontally connected to the main cavity area, and a first installation part is formed through the middle of the extended cavity area, the middle of the main cavity area, and the end of the main cavity area far from the extended cavity area for the first lighting module to be installed in the first installation part. The two ends of the first lighting module are respectively fixed in the extended cavity area and the end of the main cavity area far from the extended cavity area;

[0006] The anti-fogging component is installed in the extended cavity area and includes an air duct main body and an axial flow fan. The air duct main body is installed between the inner wall of the extended cavity area and the first lighting module. One end of the air duct main body is fixed at the end of the extended cavity area adjacent to the main cavity area and has an air inlet formed on its end face. The other end of the air duct main body is fixed at the end of the extended cavity area far from the main cavity area and has an air outlet formed at its bottom. The axial flow fan is embedded in the air inlet so that the axial flow fan can input the dry and hot air flow in the main cavity area from the air outlet, transport it along the inside of the air duct main body, and then discharge it from the air outlet;

[0007] The lamp cover structure includes an inner lens lamp cover that covers the first lighting module and is installed inside the lamp housing, and an outer lens lamp cover that covers the light-emitting side of the lamp housing. An air outlet gap corresponding to the front and back is reserved between the first lighting module and the inner lens lamp cover, so that the dry and hot air flow discharged from the air inlet can be input between the outer side of the inner lens lamp cover and the inner side of the outer lens lamp cover after passing through the air outlet gap.

[0008] As a further technical solution of the present invention: the air duct body is an arched strip that matches the inner wall of the extension cavity area, and an air duct for transporting the dry and hot air flow from the air inlet to the air outlet is formed by the air duct body and the inner wall of the extension cavity area.

[0009] As a further technical solution of the present invention: a wire outlet communicating with the inside thereof is formed on the inner side of one end of the air duct body adjacent to the main cavity area, for the wire of the axial flow fan to pass through the wire outlet.

[0010] As a further technical solution of the present invention: a second installation part is formed on the upper part of one end of the lamp housing adjacent to the extension cavity area in its main cavity area, and a high and low beam lamp module is installed in the second installation part.

[0011] As a further technical solution of the present invention: a third installation part is formed on the lower part of one end of the lamp housing adjacent to the extension cavity area in the main cavity area, and a projection lamp module is installed in the third installation part.

[0012] Compared with the prior art, the beneficial effect of the present invention is that: the present invention provides a headlamp with an anti-fogging function. Through the cooperation between the lamp housing, the first lighting module, the anti-fogging component and the lamp cover structure, the heat concentrated in the main cavity area can be input from the air outlet in the form of dry and hot air flow along with the operation of the axial flow fan, transported along the inside of the air duct body, discharged from the air outlet and input between the outer side of the inner lens lamp cover and the inner side of the outer lens lamp cover after passing through the air outlet gap, promoting the air circulation inside the lamp, making the temperatures of the extension cavity area and the main cavity area balanced, and effectively preventing fogging in the extension cavity area.

The lamp housing 10 forms a main cavity area 11 and an extended cavity area 12 that is laterally communicated with the main cavity area 11, and a first installation portion 101 is formed through the middle of the extended cavity area 12, the middle of the main cavity area 11 and one end of the main cavity area 11 away from the extended cavity area 12, for installing the first lighting module 20 into the first installation portion 101. Both ends of the first lighting module 20 are respectively fixed in the extended cavity area 12 and one end of the main cavity area 11 away from the extended cavity area 12; the anti-fogging component 30 is installed in the extended cavity area 12, and it includes an air duct main body 31 and an axial flow fan 32. The air duct main body 31 is installed between the inner wall of the extended cavity area 12 and the first lighting module 20. One end of the air duct main body 31 is fixed at one end of the extended cavity area 12 adjacent to the main cavity area 11 and has an air inlet 311 formed on its end face. The other end of the air duct main body 31 is fixed at one end of the extended cavity area 12 away from the main cavity area 11 and has an air outlet 312 formed at its bottom. The axial flow fan 32 is embedded in the air inlet 311, so that the axial flow fan 32 can input the dry and hot air flow in the main cavity area 11 from the air outlet 312, and after being transported along the inside of the air duct main body 31, it is discharged from the air outlet 312;

[0022] With reference to Figure 6 、 Figure 7 , the lamp cover structure includes an inner lens lamp cover 41 that covers the first lighting module 20 and is installed in the lamp housing 10 and an outer lens lamp cover 42 that covers the light-emitting side of the lamp housing 10. Both the first lighting module 20 and the inner lens lamp cover 41 are provided with an air outlet gap 401 corresponding to the air outlet 312 front and back, so that the dry and hot air flow discharged from the air inlet 311 can be input between the outside of the inner lens lamp cover 41 and the inside of the outer lens lamp cover 42 after passing through the air outlet gap 401, thereby promoting the air circulation inside the lamp and preventing the extended cavity area 12 from fogging.

[0023] Further, in this embodiment, with reference to Figure 5 , the air duct main body 31 is an arched strip that matches the inner wall of the extended cavity area 12, and an air duct for dry hot air to be conveyed from the air inlet 311 to the air outlet 312 is formed by the air duct main body 31 and the inner wall of the extended cavity area 12.

[0024] Further, in this embodiment, at one end of the air duct main body 31 adjacent to the main cavity area 11, a wire outlet 313 communicating with its interior is formed on the inner side for the wires of the axial flow fan 32 to pass through the wire outlet 313.
