A double ball-joint connecting rod connection device used for the connection of the adjustable bracket of the lamp

Abstract

A double-ball-joint connecting rod connection device for connecting adjustable brackets of vehicle lamps, comprising: a double-ball-joint connecting rod (5) used to connect and synchronously adjust the adjustable brackets of a plurality of light emitting units (A), the The two ends of the double-ball-joint connecting rod (5) are respectively provided with a cavity-type first ball-joint (5a) and a cavity-type second ball-joint (5b), and the interior of the cavity-type first ball-joint (5a) is provided with a ball socket (5c); the two ends of the double-ball connecting rod (5) are connected to the second adjustable brackets of different light-emitting units, and the motor ball head (1a) of the motor (1) runs through the cavity-type second ball head ( 5b), cooperate with the ball socket (5c) provided inside the first ball head (5a) to form a rotating pair. According to the present invention, the adjustable brackets of two or more light-emitting units can be adjusted to tilt up and down synchronously, so as to achieve the purpose of synchronous adjustment of different light-emitting units in the vehicle lamp. In addition, the overall volume of the far and near light unit is smaller than before, which reduces the lateral force of the motor ball head and improves the life of the motor.

Description

technical field [0001] The present invention relates to a car lamp connection structure, in particular, the present invention relates to a double-ball-joint connecting-rod connecting device used for adjustment between adjustable brackets in a car lamp, and the double-ball-joint connecting-rod connecting device is used in a car The light-emitting unit of the lamp is adjusted by tilting up and down, so that the adjustable supports of two or more light-emitting units can be adjusted by tilting up and down synchronously. Background technique [0002] Because the far and near beam lighting functions in the car lights are usually composed of different lighting units, and are respectively fixed on different adjustable brackets. At the same time, due to the angle deviation between the vehicle and the road surface caused by the vehicle under different loads and different road surface conditions, it is necessary to dynamically adjust the illumination of the far and near beams accordin...

Problems solved by technology

[0004] However, the disadvantages of the above-mentioned single-link connection method are:

[0005] Since the ball socket 5'b and the ball head 5'c of the connecting rod 5' cannot be arranged in a straight line, the volume of the connecting rod 5' is relatively large, and the two adjustable brackets 3' and 4' need to be adjusted according to the connecting rod 5'. The positions of the ball socket 5'b and the ball head 5'c are staggered horizontally, resulting in an increase in the overall volume of the far and near light unit

[0006] In addition, since the ball socket 5'b and the ball head 5'c of the connecting rod 5' cannot be arranged in a straight line, the force direction of the ball socket 5'b and the ball head 5'c of the connecting rod 5' is the same as that of the motor ball head. There is a certain distance in the direction of motion of 1'a, which generates torque and causes lateral force on the motor ball head 1'a, reducing the life of the motor
