Description

Front fog lamp with rotating shaft dimming structure

Technical Field

The utility model relates to the technical field of vehicle lamps, in particular to a front fog lamp with a novel rotating shaft dimming structure.

Background

The front and rear parts of the vehicle are generally provided with fog lamps for ensuring the driving safety under the condition of poor sight such as rainy and foggy days. The national standard GB 4785-2019 explicitly stipulates the light-adjustable requirement of the front fog lamp: the limit angle of downward adjustment of the fog lamp cut-off line is not less than 2 degrees, so that the front fog lamp optical reflector cannot be locked and installed on the lamp shell and can only be installed by adopting a movable part.

Common front fog lamp structure of adjusting luminance in the existing market is mostly as ball stud + ball nail seat mode as shown in figure 1, and this kind of structure has some problems in space occupation. This is because the supporting reflection bowl needs 2 lugs to match with the ball stud, and the space inside the lamp is very limited in most cases, and cannot meet the space required by the lugs of the reflection bowl.

According to the search, a plurality of front fog lamp products with various types of dimming structures exist at present, such as Chinese patents CN214038238U, CN214119912U, CN213118936U and the like. The front fog lamp products have advantages and disadvantages, and on the basis, the novel front fog lamp which is simpler in structure, more convenient to adjust light and better in space utilization rate is developed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a front fog lamp with a rotating shaft dimming structure, which mainly comprises a lampshade 1, a reflector 3, a lamp shell 4, a bulb 5 and an adjusting bolt 7. Wherein, the lampshade 1 and the bulb 5 are fixedly connected with the lamp shell 4; rotating shafts 9 are arranged on two sides (namely, the upper side and the lower side) of the reflector 3 perpendicular to the irradiation direction, corresponding rotating shaft mounting holes are arranged on the lamp shell 4, and the reflector 3 is movably connected with the lamp shell 4 through the rotating shafts and the rotating shaft mounting holes; the adjusting bolt 7 passes through the lamp housing 4 in parallel with the irradiation direction and is fixedly connected with the reflector 3.

Further, the front fog lamp also comprises a light shield 2 and a rear cover assembly 6, wherein the light shield 2 is fixedly connected with the reflector 3 and surrounds the bulb 5, and the rear cover assembly 2 is fixedly connected with the lamp shell 4 and protects the bulb 5.

Further, the shaft mounting hole of the lamp housing 4 is open-ended, and the opening is gradually narrowed.

Furthermore, the rotating shaft 9 and the rotating shaft mounting hole are in interference fit, so that the reflector 3 can be clamped with the lamp housing 4 and cannot be separated due to vibration.

Furthermore, the rotating shafts 9 on both sides of the reflector 3 are coaxial.

Furthermore, a nut positioning hole is formed in one side of the reflector 3 parallel to the irradiation direction, a nut 8 is fixed in the nut positioning hole, and the adjusting bolt 7 penetrates through the lamp housing 4 and then is fixedly connected with the nut 8.

Compared with the existing ball head adjusting structure, the rotating shaft light adjusting structure of the front fog lamp has a series of advantages of simple structure, low assembly difficulty, low installation space requirement and the like, flexible fixation between the reflector and the lamp shell is realized through the longitudinal rotating shaft, and the reflector is pulled to rotate in a certain angle through the adjusting bolt in the horizontal direction, so that light rays are adjusted.

Detailed Description

In order to make those skilled in the art fully understand the technical solutions and advantages of the present invention, the following description is further provided with reference to the specific embodiments and the accompanying drawings.

A front fog lamp with a rotating shaft dimming structure mainly comprises a lampshade 1, a light shield 2, a reflector 3, a lamp shell 4, a bulb 5, a rear cover component 6, an adjusting bolt 7 and a nut 8. The lamp housing 4 is an assembly body, and other parts are directly or indirectly fixed on the lamp housing 4. Specifically, the lampshade 1 and the lamp housing 4 are glued together, and the light shield 2 is fixed with the reflector 3 through screws to jointly form a light reflecting structure. The bulb 5 passes through the mounting hole on the reflector 3 and then is clamped on the lamp shell 4, and the rear cover assembly 6 is fixed with the lamp shell 4 to protect the bulb 5.

The upper side and the lower side of the reflector 3 are symmetrically provided with convex rotating shafts 9, the upper side and the lower side of the lamp shell 4 are provided with corresponding rotating shaft mounting holes, and the rotating shafts 9 are clamped in the rotating shaft mounting holes, so that the movable connection between the reflector and the lamp shell is realized. And a nut positioning hole is formed in the left tail part of the reflector 3, and the nut 8 is fixed in the nut positioning hole. A through hole (provided with a sealing ring) is arranged at the same position on the left side of the lamp shell 4, and the adjusting bolt 7 penetrates through the through hole and the sealing ring on the lamp shell 4 and then is fixedly connected with the nut 8.

The adjusting function of the front fog lamp is realized in the following manner: the adjusting bolt 7 is rotated to drive the reflector 3 to rotate around the rotating shaft 9, and the irradiation direction of light is changed accordingly, so that the dimming function is realized. The bulb 5 (model H7) is electrified to emit light, light is gathered by the light shield and the reflector and then is directionally reflected out from the optical surface of the lamp shell, and finally the fog lamp is lightened by penetrating through the white light-transmitting area of the lamp shade.

The front fog lamp is approved by customers, and the future economic benefit is considerable as a large number of new vehicle types come into the market.
