Abstract

The invention relates to the technical field of laser projection equipment, and discloses a driving mechanism used for a slip cover. The driving mechanism comprises a rack, a power gear, a driving gear, a movable base and an elastic piece, wherein the rack is arranged on the slip cover; the power gear is driven by a motor to rotate; the driving gear is engaged with the rack and the power gear; theshaft end of the driving gear is rotationally arranged on the movable base, and the movable base can be moved; and the first end of the elastic piece is arranged fixedly, and the second end of the elastic piece is arranged on the movable base. When the rack is assembled on and engaged with the driving gear, the elastic piece is compressed. After the driving mechanism is installed in plate, the elastic piece is in the compressed state, the driving gear always tends to get close to the rack under the elastic function of the elastic piece, great engagement between the rack and the driving gear is guaranteed, effective transmission is guaranteed, and then the slip cover can work smoothly. The invention further discloses a laser television.

Description

technical field [0001] The present application relates to the technical field of laser projection equipment, for example, to a driving mechanism for a sliding cover and a laser television. Background technique [0002] Laser projection equipment, such as laser TV, is a new terminal display equipment, mainly including two parts: laser projector and screen. The light output end of the laser projector is a lens, if there is no protection, there will be dust or scratches from foreign objects, etc., which will affect the display effect of the screen. Therefore, a common approach is to make an openable and closable protective sliding cover, and control the opening or closing of the sliding cover through a driving mechanism. refer to Figure 7 As shown, when using the product, control to open the slide cover and project to watch; refer to Figure 6 As shown, when the camera is turned off and not viewed, the sliding cover should be closed by control to prevent the lens from accumu...
