Description

Technical Field

[0001] The utility model relates to the field of vehicle light distance control, and more specifically to a vehicle light distance control device. Background Art

[0002] Headlights are components installed on vehicles. They are divided into high beams for long-distance lighting, low beams for general roads, fog lights that play a key role in low visibility conditions such as fog, turn signals that indicate turning direction, brake lights that prompt braking action, and daytime running lights that improve daytime visibility. High beams and low beams are especially important when driving at night, as they can illuminate the road environment for the driver, so that the driver can judge the driving route and ensure safe driving.

[0003] Chinese patent application number: CN202120409974.0, provides a car high and low beam control device. This solution changes the angle of the first reflector under the action of the first gear by adjusting the arc rod on the second fixed rod inside the frame, so that the angle of the car light can be adjusted, thereby changing the car light illumination angle. However, during the use of the headlights, especially when driving at night, the headlights need to be illuminated at a farther distance so that the driver can have enough time to respond to emergencies. When driving in urban areas, the illumination distance needs to be reduced to avoid dazzling oncoming vehicles. The headlights mentioned in the above patent are not convenient for controlling the illumination distance, which is not conducive to nighttime vehicle driving.

[0004] Therefore, a vehicle headlight distance control device is proposed in response to the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a headlight distance control device, which can open or close the reflector by changing the angle of the reflector, thereby reflecting the light emitted by the headlight body to different degrees. When the reflector is closed, the light emitted by the headlight body is concentrated and the irradiation distance is farther. When the reflector is opened, the light emitted by the headlight body is scattered and the irradiation distance is shorter, thereby controlling the distance of the light emitted by the headlight body.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0026] The position of the reflector 210 is limited by the fixing rod 208 and the connecting head 209. When the angle of the reflector 210 changes, the reflector 210 is in a retracted or extended state. When the reflector 210 is retracted, the light emitted by the lamp body 202 is concentrated and the irradiation distance is farther; when the reflector 210 is extended, the light emitted by the lamp body 202 is scattered and the irradiation distance is shorter, thereby realizing the control of the light distance of the lamp body 202.

[0027] A hinge 214 is hinged on the outer side of the bottom end of the reflective sheet 210, and a connecting shaft 213 is hinged on the end of the hinge 214 away from the reflective sheet 210. The connecting shaft 213 passes through the positioning ring 201, and the connecting shaft 213 is slidably connected to the positioning ring 201. A hinge 212 is hinged on the end of the connecting shaft 213 away from the hinge 214, and a connecting rod 211 is hinged on the bottom end of the hinge 212.

[0028] The adjustment component 2 also includes a fixed block 203, which is fixedly installed at the bottom end of the positioning ring 201. The bottom end of the fixed block 203 is rotatably connected to a screw rod 204, and a motor 205 is installed at the bottom end of the screw rod 204. The transmission end of the motor 205 is fixedly connected to the screw rod 204, and the bottom end of the motor 205 is fixedly connected to the bottom end inside the lamp body 1.

[0029] The outer end of the screw rod 204 is sleeved with a threaded sleeve 206 , and the threaded sleeve 206 is threadedly connected to the screw rod 204 .

[0030] The outer end of the screw sleeve 206 is fixedly connected with a plurality of hinge joints 207 which are equidistantly distributed in a ring shape. The hinge joint 207 is hinged to one end of the connecting rod 211 away from the hinge 212 .

[0031] The outer end of the positioning ring 201 is fixedly connected with a plurality of convex blocks which are equally spaced in a ring shape, and the convex blocks are sleeved on the outside of the connecting shaft 213, and the convex blocks are slidably connected with the connecting shaft 213;

[0032] The motor 205 drives the screw rod 204 to rotate, the screw rod 204 drives the screw sleeve 206 to move, the screw sleeve 206 drives the connecting rod 211 to move through the hinge 207, and the connecting rod 211 drives the reflective sheet 210 to move through the hinge 212, the connecting shaft 213 and the hinge 214. The angle of the reflective sheet 210 can be changed, so that the reflective sheet 210 can be adjusted to be retracted or opened.

[0033] Specific implementation process: The lamp body 1 is installed at a suitable position on the vehicle body. When the distance of the vehicle light needs to be adjusted, the motor 205 is started, and its transmission end drives the screw rod 204 to rotate. The rotation of the screw rod 204 causes the screw sleeve 206 threadedly connected thereto to move up and down along the screw rod 204. The hinged joint 207 at the outer end of the screw sleeve 206 is hinged to one end of the connecting rod 211. The other end of the connecting rod 211 is connected to the reflector 210 through the hinge 212, the connecting shaft 213 and the hinge 214. When the screw sleeve 206 moves up and down, the connecting rod 211 , hinge 212, connecting shaft 213 and hinge 214 are used to push and pull the reflector 210. Since the reflector 210 is hinged to the connector 209 and is restricted by the fixing rod 208, the angle of the reflector 210 will change under the push and pull action. When the reflector 210 is retracted, the light emitted by the lamp body 202 is concentrated and the irradiation distance is farther; when the reflector 210 is opened, the light emitted by the lamp body 202 is scattered and the irradiation distance is shorter, thereby realizing the control of the lighting distance of the lamp body 202.
