Description

Magnetic suspension light-changing mechanism

Technical Field

The invention belongs to the technical field of automobile lighting equipment, and particularly relates to a magnetic suspension light-changing mechanism.

Background

In the existing automotive lighting application, the dual-light automotive lens has become a great trend to replace the traditional high beam light and low beam light which take halogen lamps as lamp beads and expose the lamp beads because of the advantages of low power consumption, high integration degree, high brightness, smaller volume, more beautiful appearance and the like. Since the distance light and the near light of the double-light automobile lens are integrated in the same lens, the distance light and the near light need to be distinguished, and a common method is to install a light changing structure in the lens to achieve the purpose of changing the distance light or the near light.

The light changing mechanism utilizes the electromagnet (or the motor) to do horizontal, longitudinal and other axial movements to drive the connecting rod to do up-and-down or rotation and other circular movements to realize structural displacement, so that the electromagnet (or the motor) and the mechanism can realize the required displacement only by mechanical and spring cooperation for a plurality of times, and therefore, the light changing mechanism has larger mechanical abrasion and greatly limited service life. The electromagnet and the mechanism of the car lamp dimming mechanism have the noise of abrasion collision due to structural reasons, and simultaneously, because of more mechanical parts and large abrasion, the car lamp dimming mechanism has the disadvantages of delay after a certain service life and slow jamming reaction, so that the left car lamp and the right car lamp are easily unsynchronized left and right in the switching of the far light and the near light.

Therefore, in view of the above, research and improvement are made on the existing structure and defects, and a magnetic suspension light changing mechanism is provided, so as to achieve the purpose of higher practical value.
