Problems solved by technology

However, in the process of moving the lens by the motor, due to the heavy weight of the lens, the motor needs a large thrust, which results in high energy consumption of the motor, which is not conducive to long-term shooting by the camera module.

Embodiment Construction

[0075] In order to facilitate the understanding of the optical lens set provided in the embodiment of this application, the meanings of the English abbreviations and related nouns involved in this application are as follows:

[0076] The optical axis is an axis passing through the center of each lens.

[0077] The side of the object is bounded by the lens, the side where the subject is located is the object side, and the surface of the lens close to the object side is called the object side.

[0078] The image side is bounded by the lens, the side where the image of the subject is located is the image side, and the surface of the lens close to the image side is called the image side.

[0079] Positive power, also known as positive refractive power, means that the lens has a positive focal length.

[0080] Negative power, also known as negative refractive power, means that the lens has a negative focal length.

[0081] Focal length (focal length), also known as focal length, ...

Abstract

The invention provides an optical lens, a camera module and electronic equipment. The optical lens comprises a prime lens and a focusing lens. The focusing lens is located on the object side of the prime lens. The focusing lens comprises a motor, a first lens and a second lens. The second lens is located on the image side of the first lens. When the relative position of the second lens and the first lens changes, the focal power of the focusing lens changes. The motor includes a first driving portion and a second driving portion. The first driving part is connected with the first lens. The first driving part is used for driving the first lens to move in the direction perpendicular to the optical axis of the prime lens. The second driving part is connected with the second lens. The second driving part is used for driving the second lens to move in the direction perpendicular to the optical axis of the prime lens. In the focusing process of the optical lens, the energy consumption of the motor is low.

Description

technical field [0001] The present application relates to the lens field, in particular to an optical lens, a camera module and electronic equipment. Background technique [0002] With the popularization and development of smart phones, taking pictures with mobile phones has become a commonly used shooting method. The camera module of a traditional mobile phone includes a motor and a lens. Wherein, during the photographing process of the camera module, the motor drives the lens to move along the optical axis to realize the focusing requirement of the camera module. However, in the process of moving the lens by the motor, due to the heavy weight of the lens, the motor needs a greater thrust, resulting in greater energy consumption of the motor, which is not conducive to long-term shooting by the camera module. Contents of the invention [0003] The present application provides an optical lens, a camera module and an electronic device with low motor energy consumption duri...
