Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, in particular to a novel defogging structure for automobile lamps. Background Art

[0002] Due to the small space inside the headlights and poor air flow, condensation often occurs on the plastic outer cover. The current mainstream methods to eliminate condensation on the outer cover of headlights are: adding desiccant to absorb moisture, adding anti-fog paint to the mask, and adding ventilation holes to increase air circulation. However, since desiccant has a shelf life and becomes ineffective after it expires, and anti-fog paint has limited effect and cannot work in harsh environmental conditions, the effect of ventilation holes and breathable semi-permeable membranes will gradually deteriorate with longer use time. Utility Model Content

[0003] In view of this, the problem to be solved by the utility model is to provide a novel vehicle lamp defogging structure.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A novel vehicle lamp defogging structure comprises a cooling device and a defogging device installed inside a lamp housing;

[0006] A cooling fan is provided at the air inlet of the cooling air duct of the cooling device, and the air outlet of the cooling air duct faces the light source that generates heat;

[0007] A defogger fan is arranged at the air inlet of the defogger air duct of the defogger device, and the air outlet of the defogger air duct faces the plastic mask.

[0008] The air outlet of the defogger air duct extends along the length direction of the plastic mask and has an arc-shaped structure.

[0009] The air outlet of the cooling air duct and the air outlet of the defogger air duct are both constructed with a limit rod and a concave internal threaded platform, the two groups of limit rods are diagonally arranged, and the two groups of concave internal threaded platforms are diagonally arranged;

[0011] The cooling air duct and the defogger air duct both include an upper tube portion and a lower tube portion, and the upper tube portion and the lower tube portion are both connected via a snap-fit ​​device.

[0012] The clamping device includes an n-shaped clamping head and a pipe sleeve corresponding to the n-shaped clamping head. A clamping platform is constructed on the inner wall of the pipe sleeve. The cross-sectional area of ​​the clamping platform continuously increases in the direction away from the inlet end of the pipe sleeve. The front surface of the clamping platform is a sloped surface, and the top surface of the clamping platform is a plane.

[0013] The advantages and positive effects of the utility model are:

[0014] The hot air flow blown by the cooling fan to the inner cavity of the lamp housing is gathered into the defogger duct by the defogger fan, and then transferred to the plastic mask through the defogger duct, thereby accelerating the dissipation of fog on the inner surface of the mask.

[0025] like Figure 1 to Figure 2 As shown, the utility model provides a novel vehicle lamp defogging structure, comprising a cooling device 1 and a defogging device 2 installed inside the lamp housing;

[0026] A cooling fan 12 is provided at the air inlet of the cooling air duct 11 of the cooling device 1. The air outlet of the cooling air duct 11 faces the light source that generates heat. The cooling fan 12 blows the heat generated by the light source to the inner cavity of the lamp housing through the cooling air duct 11 to avoid heat accumulation near the light source, thereby achieving a continuous heat dissipation effect on the light source.

[0027] A defogger fan 22 is provided at the air inlet of the defogger duct 21 of the defogger device 2, and the air outlet of the defogger duct 21 faces the plastic mask. The hot air flow blown into the inner cavity of the lamp housing by the cooling fan 12 is gathered into the defogger duct 21 by the defogger fan 22, and the hot air flow is transferred to the plastic mask through the defogger duct 21, thereby accelerating the dissipation of fog on the inner surface of the mask. In the present technical solution, as long as the light source (headlight) is in the on state, hot air flow will always be transferred to the plastic mask, thereby avoiding the occurrence of fog on the inner surface of the mask, thereby realizing the function of continuous defoggering of the mask.

[0028] Specifically, the air outlet of the defogger duct 21 extends in an arc-shaped structure along the length direction of the plastic mask, so that the air outlet range of the defogger duct 21 corresponds to the contour of the plastic mask, thereby transmitting all-round hot air flow to the inner surface of the plastic mask.

[0029] Specifically, the air outlet of the cooling air duct 11 and the air outlet of the defogger air duct 21 are both constructed with positioning rods 31 and concave inner threaded platforms 32. The two sets of positioning rods 31 are diagonally arranged to play a positioning role when installing the cooling fan 12 and the defogger fan 22. After the positioning rods 31 are sleeved and connected, the concave inner threaded platforms 32 are aligned with the screw installation holes on the cooling fan 12 and the defogger fan 22, thereby facilitating subsequent threaded fixing.

[0030] The two groups of the concave internal threaded platforms 32 are also arranged diagonally, and the cooling fan 12 and the defogger fan 22 are inserted into the positioning rod 31 and are threadedly connected to the concave internal threaded platforms 32 by fixing screws; only two groups of fixing screws are needed to fix the cooling fan 12 and the defogger fan 22, which reduces the assembly workload of the workers and improves the installation efficiency.

[0031] like Figure 3 to Figure 4 As shown, specifically, the cooling air duct 11 and the defogger air duct 21 both include an upper tube portion and a lower tube portion, the upper tube portion and the lower tube portion are designed to be joined, and the upper tube portion and the lower tube portion are both connected by a snap-fit ​​device;

[0032] like Figures 3 to 5 As shown, the buckle device includes an n-shaped clamp head 41 and a pipe sleeve 42 corresponding to the n-shaped clamp head 41. A clamping platform 43 is constructed on the inner wall of the pipe sleeve 42. The cross-sectional area of ​​the clamping platform 43 increases continuously in the direction away from the inlet end of the pipe sleeve 42. The top surface of the clamping platform 43 is a plane, and the front surface of the clamping platform 43 (the end surface of the n-shaped clamp head 41 that first contacts the n-shaped clamp head 41 when the n-shaped clamp head 41 enters from the inlet end of the pipe sleeve 42) is a sloped surface, which plays a guiding role, so that the n-shaped clamp head 41 can be inserted into the inner cavity of the pipe sleeve 42. The n-shaped clamp 41 undergoes a certain elastic deformation in the direction. As the n-shaped clamp 41 continuously enters into the pipe sleeve 42, when the clamping platform 43 is completely in the notch on the n-shaped clamp 41, the n-shaped clamp returns to the state before deformation, and the top surface of the clamping platform 43 abuts against the n-shaped clamp 41, so that the clamping platform 43 and the notch on the n-shaped clamp 41 are in a clamping state; when it needs to be disassembled, the n-shaped clamp 41 is pushed in the direction away from the clamping platform 43, and the clamping platform 43 is separated from the notch of the n-shaped clamp 41 through its elastic deformation;

[0033] In this embodiment, the n-shaped clamp 41 is configured on the lower tube portion, and the tube sleeve 42 is configured on the upper tube portion.

[0034] The working principle and working process of the utility model are as follows:

[0035] When the light source needs to be cooled, the cooling fan 12 is turned on, and the cooling fan 12 blows the heat generated by the light source to the inner cavity of the lamp housing through the cooling air duct 11 to avoid heat accumulation near the light source;

[0036] When the mask needs to be defogged, turn on the defog fan 22, and the hot air flow blown into the inner cavity of the lamp housing by the cooling fan 12 is gathered into the defog duct 21 through the defog fan 22, and the hot air flow is transferred to the plastic mask through the defog duct 21, thereby accelerating the dissipation of fog on the inner surface of the mask. As long as the light source (headlights) is turned on during driving, hot air flow will always be transferred to the plastic mask, thereby avoiding the formation of fog on the inner surface of the mask.

[0037] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the utility model should still fall within the scope of this patent.
