Problems solved by technology

[0005] The main technical problem to be solved by the present invention is to provide a power device for driving the rotation of the lens barrel of the projection lens group, which solves the problem that the overall length of the reduction motor is relatively long due to the fact that the motor and the planetary gear set are mostly directly connected axially together. The problem of long length, and the problem of loud noise caused by geared motors mainly relying on gears meshing to transmit energy during the entire energy transmission process

Abstract

The invention provides a power device for driving a lens barrel of a projection lens group to rotate. The device comprises a projection rotation device, a coupling rubber wheel, a planetary gear speedreduction box internally provided with a planetary gear set, a belt pulley, a direct current motor, a transmission structure fixing support, a first installation groove and a second installation groove which are used for installing the planetary gear speed reduction box and the direct current motor respectively, a belt, a belt wheel fixing support, a third installation groove which is used for installing the belt wheel fixing support, a belt wheel center shaft, an automatic gap adjusting device, and a channel arranged in the transmission structure fixing support and used for installing the automatic gap adjusting device. According to the power device for driving the lens barrel of the projection lens group to rotate, the problem that the overall length of an existing gear motor is large due to the fact that most of the motor and planetary gear sets are directly and axially connected into a whole is solved, and the problem that noise is large due to the fact that the gear motor mainlyrelies on gear engagement to transmit energy in the whole energy transmission process is solved.

Description

technical field [0001] The invention relates to the technical field of power devices, in particular to a power device for driving the rotation of a lens barrel of a projection lens group. Background technique [0002] At present, the projection lamps used in automobiles on the market usually have two projection effects: one is to project a static pattern through a fixed lens; the other is to install a permanent magnet synchronous motor (such as a 220v AC low-speed permanent magnet motor ) to drive the lens rotating part to rotate through a transmission mechanism such as a belt to project a dynamic pattern. [0003] But in practice, it is found that most of the patterns projected through the fixed lens are only static patterns, which generally have the disadvantages of monotonous patterns and lack of aesthetic feeling; and the common geared motors on the market, such as the m10 small gear reducer, mostly combine the motor and The planetary gear sets are directly connected ax...
