Problems solved by technology

The built-in camera module type portable electronic device is more convenient to carry than the external camera or camera module type portable electronic device, but the function of the built-in camera module is relatively limited due to the limitation of the space of the portable electronic device body
For example, a lens module with a better zoom function needs to occupy a relatively large space, so it is difficult to accommodate in a space-constrained portable electronic device body

Description

【Technical field】 [0001] The invention relates to a zoom lens module, in particular to a zoom lens module applied to a portable electronic device with a built-in camera module. 【Background technique】 [0002] Portable electronic devices with digital camera functions (such as mobile phones, personal digital assistants, etc.) are widely used today, so that the portable electronic devices can be used as cameras to take pictures and video clips. [0003] Portable electronic devices with digital camera functions currently on the market include: external cameras or camera modules and built-in camera modules. The modular portable electronic device with an external camera or camera is connected to an external camera or video head by providing a connection port on the body of the portable electronic device or on the flip cover or slide cover. Since the external camera is independent from the portable electronic device, it can be equipped with a zoom lens module to improve image qual...
