Abstract

The invention discloses an annular pointer motion structure for an automobile meter, which comprises a pointer and a motor, wherein the pointer is arranged on an annular driven disc, the annular driven disc is arranged between a support bracket and a cover plate, and connected with the support bracket by a circumferential sliding pair, the outer circumference of the annular driven disc is engaged with a drive gear, and the drive gear is arranged on an output shaft of the motor. The annular driven disc transmits the motion of the motor to the pointer; the using space in the center of the meter is saved; plastic parts used for fixing a display screen are saved; the assembling process of the display screen is simplified; the thickness of the product is reduced; the corner of the pointer in the prior art is reduced; the optical uniformity of the lighted pointer is effectively improved; rolling balls slide in an annular rail groove of the support bracket to drive the annular driven disc and the pointer to rotate around the center, fewer spare parts that are simple in structure and convenient to assemble are adopted; and due to smaller rolling friction forces of the rolling balls, the drive burden of the motor is reduced, and the reliability of the motion structure is improved.

Description

Technical field: [0001] The invention relates to the mechanical field, in particular to a driving structure of an instrument pointer, in particular to a circular pointer movement structure of an automobile instrument. Background technique: [0002] With the digital development of automotive electronics, display screens are more and more widely used in automotive instrumentation, and the content required to be displayed is becoming more and more abundant. Many important driving information, safety information and entertainment information in the car need to be displayed through the display screen. [0003] At present, the most popular form of medium and high-end automotive instrumentation is DIG technology. The full name of DIG is Display In Gauge, that is, the display screen is displayed in the center of the instrument panel. The display screen is in the center of the watch head, which can not only maximize the display, but also have a very good appearance. At present, the...
