Abstract

The invention provides a projection module and an electronic device. The electronic device comprises a first machine body, a second machine body and a projection module, wherein the second machine body is pivoted to the first machine body, so that the first machine body rotates relative to the second machine body; the projection module comprises a light machine, a balance weight piece and a pivoting piece; the light machine is used for projecting image light beams; the balance weight piece is arranged on the light machine; the pivoting piece is connected with the light machine and the first machine body; and when the first machine body rotates relative to the second machine body, the light machine rotates relative to the first machine body through the pivoting piece under the gravity of the balance weight piece, so that the light machine projects the image light beams towards the regular direction.

Description

technical field [0001] The invention relates to a projection module, in particular to a projection module and an electronic device assembled on an electronic device. Background technique [0002] Projectors are widely used in video playback, presentation data playback, etc. With the advancement of technology, micro-projectors have gradually become the mainstream of the market due to their small size, light weight, and easy operation, especially when used with laptops. , and has become an important tool in mobile commerce because of its great convenience. [0003] Yet existing microprojection device that is arranged on notebook computer, its projection lens all must be adjusted along with the angle between the screen of notebook computer and main frame. Once the user rotates the screen, he must immediately rotate and adjust the projection angle of the micro-projection device to maintain the original image quality, which often causes inconvenience to the user.
