Description

Bifocal lens projection lamp

technical field

The utility model relates to a car lamp, in particular to a car headlight.

Background technique

Existing headlights have the function of switching between low beam and high beam, but the structure of the existing headlights is relatively complicated or unreasonable, resulting in a high failure rate and unsatisfactory lighting effects. For example, the application number is 200820203979.2, the authorized announcement number is CN201322237Y, and the utility model patent is named "a projection lamp holder for vehicle headlights". The shading sheet is pivotally mounted on the pivot, and the shading sheet is connected to the electromagnetic coil through a push rod. When the electronic coil is energized or powered off, the push rod drives the shading sheet to rotate along the pivot to realize the switching between high beam and low beam. When the headlights switch between high beam and low beam, the moment required for the rotation of the visor is large, and the volume of the electromagnetic coil required is also large. Moreover, when it is in low beam, the upper edge of the visor forms a certain angle of inclination relative to the bottom surface. , the emitted light has a small range on the ground, and the irradiation effect is not ideal.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a double light lens projection vehicle lamp with simple structure, small electromagnetic moment and good irradiation effect.

The technical scheme that the utility model solves its technical problem adopts is:

A bifocal lens projection vehicle lamp, comprising a lamp body and a lampshade. The lamp body includes a lamp cup, a light-shielding sheet and an electromagnet. A shading plate is installed at the opening of the cup, the coil of the electromagnet is fixed on the shading plate, a return spring is installed on the armature, the shading plate is hinged on the shading plate, and the armature is connected with the shading plate to drive the shading plate along the hinge axis. Flip.

The beneficial effects of the utility model are: the shading sheet of the utility model is hinged on the shading plate, the coil of the electromagnet is fixed on the shading sheet, the armature is connected with the shading sheet, and when the light is far away, the electromagnet is energized to attract the armature to drive the shading sheet along the hinge The shaft is turned over, the turning moment is small, the shading plate is parallel to the ground after turning over, and the irradiation effect is ideal. vehicle lighting.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Detailed ways

Referring to Fig. 1 and Fig. 2, a bifocal lens projection vehicle lamp includes a lamp body and a lampshade, and the lamp body includes a lamp cup 10, a shading plate 4, a shading sheet 18, an electromagnet 7 and a "ji"-shaped connecting rod 8 The tail of the lamp cup 10 is provided with a screw 1, the screw 1 is screwed with a nut 2, the light shield 4 is fixed on the opening of the lamp cup 10 by the screw 3 to cover the opening of the lamp cup, and the coil of the electromagnet 7 is fixed on On the light-shielding plate 18, the two ends of the coil are drawn out through the wire 6, and a quick joint 5 is arranged at the end of the wire 6, a return spring 19 is installed on the armature, and the light-shielding plate 4 is provided with two supporting pieces 12, and the light-shielding plate 18 The two ends of the shading sheet 18 are hinged on the supporting sheet 12, and the two ends of the shading sheet 18 are bent 90 degrees to the same side to form a rotating arm 11, and a connecting piece 9 is hinged between the two rotating arms 11, and the connecting piece 9 is set There is a U-shaped notch, the armature of the electromagnet 7 is movably clamped in the U-shaped notch, and the connection drives the shading sheet 18 to turn over 90 degrees along the hinge axis; the two ends of the connecting rod 8 pass through the rotating arms 11 on both sides respectively. The connecting rod 8 and the two braces 12 form a hinge shaft, and the connecting rod 8 is bent toward the light shield 4 through the position of the two braces 12 so that the end thereof leans against the surface of the light shield 4 . When the shading plate 18 rotates, one positioning point is that the shading plate 4 blocks the shading plate 18, and the other positioning point is the end point of the electromagnet stroke or the connecting rod 8 blocks the connecting piece 9. Therefore, the rotation angle of the shading plate 18 can be adjusted according to the stroke of the armature. To determine, as when the armature is longer, the rotation angle of the light shielding plate 4 can also be changed according to the bending degree of the position where the connecting rod 8 passes through the two braces 12 .

When the light is far away, the electromagnet is energized to attract the armature, which drives the shading sheet to flip along the hinge axis. The turning moment is small. After the shading sheet is turned over, it is parallel to the ground, and the irradiation effect is ideal. The utility model has the advantages of simple structure, safety and reliability, and can be widely used in various vehicle lighting.

The lampshade of the present utility model is composed of a lens bracket 15, a lens 17 installed at the lower end of the lens bracket 15, and a pressure ring 16. The inner side of the lens bracket 15 is provided with two stepped surfaces, and the edge of the lens 17 is provided with a lens step resting on the lower step. On the surface, the upper edge of the pressure ring 16 is provided with a pressure ring step, and the pressure ring step is fixed on the upper step surface by a screw 13, and the lower edge of the pressure ring 16 is against the surface of the lens 17, and the lens holder 15 is provided with a fixing screw 14, after the lamp body and the lampshade are fastened, the screw is screwed on the fixing screw 14 through the hole pre-set on the lamp body to fix the lamp body and the lampshade, the assembly method is simple and reliable.

More than just the specific implementation of the utility model, can not limit the scope of protection of the utility model, as long as the equal modification and change done according to the scope of protection of the utility model, such as one side of the shading plate 18 is hinged on the shading plate 4, another The armature connection of one side electromagnet and the like still belong to the scope covered by the invention.
