Problems solved by technology

For the part where the thickness of the side wall of the lens barrel is small, that is, where the lens barrel is close to the image side, the torque that fits with the lens is usually relatively large, so that the torque on the lens barrel is not uniform, and seriously, it will directly cause damage to the lens barrel

Abstract

The invention discloses a leans barrel which comprises a side wall. The thickness of the side wall close to the object side of the lens barrel is greater than that of the image side of the lens barrel. The outer surface of the side wall is provided with a plurality of thread groups at intervals around the central axis of the lens barrel; each thread group comprises a plurality of threads; the extending direction of each thread is continued by the extending direction of a corresponding thread in another adjacent thread group; and in the plurality of threads in each thread group, the surface areas of the threads close to the object side of the lens barrel are larger than those of threads close to the image side of the lens barrel. The technical scheme also provides a lens module with the lens barrel.

Description

technical field [0001] The invention relates to the field of optical systems, in particular to a lens barrel with uniform torsional force and a lens module having the lens barrel. Background technique [0002] With the rapid development of multimedia technology, digital cameras, video cameras and mobile phones with cameras are more and more popular among consumers. While people put forward higher requirements for the image quality of objects captured by digital cameras, video cameras and mobile phone cameras, the Demand for products such as digital cameras, video cameras and mobile phones with cameras is also increasing. In photographic devices such as digital cameras, video cameras and mobile phone cameras, the lens module is an indispensable component. [0003] The lens module usually includes a lens barrel, a lens mount, an optical imaging element and an image sensor. The optical imaging element is accommodated in the lens barrel, and the image sensor is arranged on the...
