Abstract

The invention provides a lifting mechanism used for lifting objects. The lifting mechanism comprises a lifting piece connected to an object, a driving piece and a gear assembly connected to the driving piece. The transmission assembly is connected between the gear assembly and the lifting piece. The driving part drives the gear assembly to rotate, the gear assembly drives the transmission assemblyto rotate to drive the lifting part to ascend or descend, the transmission assembly is provided with a buffer mechanism, and the buffer mechanism is used for blocking relative movement of the transmission assembly and the gear assembly so as to prevent abnormal rotation of the gear assembly and avoid damage caused by tooth breakage of the gear assembly and the transmission assembly. The inventionfurther relates to a camera device provided with the lifting mechanism and an electronic device provided with the camera device.

Description

Technical field [0001] The present invention relates to the technical field of mechanical transmission, in particular to a lifting mechanism, a camera telescopic device provided with the lifting mechanism, and an electronic device provided with the camera telescopic device. Background technique [0002] Existing electronic devices, such as mobile phones, tablet computers, etc., usually have electronic devices such as lens modules on top of the electronic devices. The lens module of an existing full-screen mobile phone is generally hidden on the back of the display screen. When it is not used, the lens module is retracted inside the mobile phone, and the lens module is extended to take pictures when needed. Due to the limitation of mobile phone space, the installation position, transmission mode, and volume of the lens module inside the mobile phone are all issues that need to be considered. In the prior art, a screw nut lifting mechanism is generally used to drive the lens modul...
