Problems solved by technology

For this reason, in the prior art, the following measures are often considered: one is to miniaturize the size of the camera module. However, under the premise of meeting the basic functional requirements and structural strength requirements, the current reduction in the size of the camera module has tended to The second is to do special treatment on the local structure of the camera module, such as setting chamfers or rounded corners, so as to adapt to the shape of the equipment outline, and arrange the camera module close to the corner, but this method is still limited by the existing camera modules. The structural characteristics of the module and its components; the third is to use a hidden front camera, but in this scheme, due to the addition of a telescopic operating mechanism, the design and manufacturing costs of the equipment have increased, and at the same time a new Potential failure

Embodiment approach 1

[0113] Embodiment 1 (see 5A and 5B)

[0114] Set the camera module at the middle position above the screen, because in the above module, the AF magnet and the AF ball track are only set on one side a of the AF carrier, and the opposite side c is not provided with the AF magnet and the ball track , so the width of the side is relatively narrow, and this narrow side can be set close to the edge of the screen (such as Figure 5A shown). On the two sides adjacent to the side a with the AF ball track, one side d is not provided with an OIS magnet, and the width of this side is relatively narrow, and this side can also be set close to the edge of the screen (such as Figure 5B shown). In this case, the optical axis of the lens is closer to the edge of the screen than the geometric center of the camera module, the components of the camera module except the lens body are farther away from the edge of the screen, and the lens is closer to the edge of the screen.

Embodiment approach 2

[0115] Implementation mode two (see Figure 6A )

[0116] The camera module is arranged at the top of the screen near the corner, which can be arranged at the top of the screen near the upper left corner or at the top of the screen near the rounded corner of the upper right corner. At the same time, one corner of the camera module is set to be arc-shaped, and the arc of the arc angle is roughly the same as the arc of the round corner of the screen, and the arc-shaped side of the camera module corresponds to the round corner at the top of the screen.

[0117] In the above module, the AF magnet and the AF ball track are only arranged on one side a of the AF carrier, and the opposite side c is not provided with the AF magnet and the ball track. Since the magnet and the ball track are omitted on this side, the width narrower, the narrow side can be set on the side close to the left side of the screen, so that the optical axis of the lens is closer to the right side of the screen ...

Embodiment approach 3

[0120] Embodiment three (see Figure 6B )

[0121] The camera module is arranged at the top of the screen near the corner, which can be arranged at the top of the screen near the upper left corner or at the top of the screen near the rounded corner of the upper right corner. At the same time, one corner of the camera module is set to be arc-shaped, and the arc of the arc angle is roughly the same as the arc of the round corner of the screen, and the arc-shaped side of the camera module corresponds to the round corner at the top of the screen.

[0122] In the above module, the AF magnet and the AF ball track are only arranged on one side a of the AF carrier, and the opposite side c is not provided with the AF magnet and the ball track. Since the magnet and the ball track are omitted on this side, the width Narrower, the narrow side can be set on the side near the top of the screen, so that the optical axis of the lens is closer to the upper edge of the screen than the geometri...

Abstract

The invention relates to a camera module, a lens assembly, a driving motor thereof and electronic equipment. The driving motor comprises a fixed part, a movable part and a driving component, the movable part comprises a bearing seat suitable for being fixedly connected with an optical lens of the lens assembly, and the driving component can drive the movable part to move relative to the fixed part. According to the invention, a movement guide is provided between the movable part and the fixed part, which movement guide is arranged in the lateral region of the carrier and is arranged asymmetrically such that the geometric center of the carrier is biased towards one side with respect to the optical axis. Therefore, the lens assembly and the camera module can be arranged at the position, closer to the edge or the corner, of the display screen of the electronic equipment, so that the utilization rate of the screen side is improved, and a larger screen-to-body ratio can be achieved.

Description

technical field [0001] The present invention relates to the field of optical imaging technology, in particular, the present invention relates to a driving motor suitable for a lens assembly of a camera module, a lens assembly and a camera module, the lens assembly and the camera module particularly include the drive motor. The invention also relates to an electronic device including the camera module. Background technique [0002] With the popularization of mobile electronic devices, the related technologies of camera modules (used to obtain images, such as video or images) used in mobile electronic devices have developed rapidly and made great progress. , industrial production and many other fields have been widely used. In order to meet the market demand, at least one camera module is usually configured on the body of a portable terminal (such as a smart phone) popularized due to the development of mobile communication technology, so a miniaturized and thinner camera mod...
