The invention provides a transmission structure comprising motors, gear rods, clutches and arc-shaped racks. Each clutch comprises a second worm wheel and a regulation gear. The regulation gears are engaged with the arc-shaped racks. Each gear rod comprises a second worm. Each second worm and the corresponding second worm wheel form a second worm wheel and worm transmission assembly. The motors drive the gear rods, the clutches and the arc-shaped racks to move in sequence. The invention further provides a rearview mirror driver comprising a support and the transmission structure mentioned above. The transmission structure is installed on the support. The rearview mirror driver is convenient and rapid to assemble and disassemble, and a large and heavy lens can be driven through the rearview mirror driver of a small specification.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a transmission structure and a rearview mirror driver. Background technique [0002] Patent document CN201580312U discloses a mirror driver for an automobile rearview mirror, which includes a base, two motors disposed in the base, two transmission gears, and two semi-annular racks. Both are provided with teeth meshing with transmission gears, the bottom of each rack is provided with a guide rail, the two racks are on the circumference of the same circle, and the central axes of the hypothetical circles of the two racks are Parallel to the axes of the output shafts of the two motors, the axis of each transmission gear is on the same straight line as the axis of the output shaft of the corresponding motor, and the base is provided with two arcs for sliding fit of the corresponding guide rails. shaped groove. According to the self-report of the patent document, the mirror drive...
