Abstract
The utility model provides an automobile instrument annular pointer movement structure, which comprises a pointer and a motor. The pointer is arranged on an annular driven plate. The annular driven plate is arranged between a support frame and a cover plate. The annular driven plate and the support frame are connected with each other through a sliding pair in the circumferential direction. The outer circumference of the annular driven plate is engaged with a driving gear. The driving gear is arranged on the output shaft of the motor. The annular driven plate transmits the movement of the motor to the pointer. According to the utility model, the central usage space of a dial is saved and plastic parts for fixing a display screen are not needed. The installation operation of the display screen is simplified and the thickness of a product is compressed. Meanwhile, the number of bending angles of the point in the prior art is reduced and the lighting uniformity of the pointer after being lightened is effectively increased. The driven plate and the pointer are driven to rotate around the center of the dial through the sliding of a rolling ball in an annular rail groove arranged on the support frame. The automobile instrument annular pointer movement structure has the advantages of simple structure, convenient installation and fewer parts. Meanwhile, the rolling friction force of the rolling ball is smaller and the motor-driven burden is relieved. The reliability of the movement structure is also increased.
