Abstract

The invention relates to a lens adjusting module and a projection device. The lens adjusting module comprises a base, a support component, a first drive component and a first drive unit. The base is provided with a first side. The support component is provided with a third side. The third side corresponds to the first side, and the third side is provided with a first holding space. The first holding space is provided with a first surface and a second surface in the first direction. The first surface and the second surface are oppositely arranged. The first drive component comprises a first drive block and a first elastic component. The first elastic component is arranged on the first drive block and exposes out of the first drive block. The first drive component is placed in the first holding space, and the first drive component abuts against the first surface and the second surface. The first drive unit is connected with the first drive component; the first drive unit is used to drive the first drive component to bring the support rod and the lens to move in the first direction. According to the invention, while the drive component is being driven by the drive unit, the support component and the lens are subject to displacement, which eliminates the empty stroke and increases the use feel and the user's experience.

Description

technical field [0001] The invention relates to the field of projection devices, in particular to a lens adjustment module and a projection device having the lens adjustment module. Background technique [0002] In recent years, large screen has become the most popular keyword in the display field, and the product in the leading position of large screen is none other than the projection device. With the decline in the price of the projection device and the enrichment of its functions, the projection device market has obtained unprecedented development opportunities. , which are widely used in homes, offices, schools and entertainment venues. [0003] Generally, after the position of the projection device is determined, the position of the projection lens is adjusted by the driving unit, so that the projected image is located at the target position, thereby ensuring the projection effect. In the existing projection device, due to the actual manufacturing tolerance of the par...
