This application claims priority to Chinese Patent Application No. 201921694341.8, filed on Oct. 10, 2019, the disclosure of which is hereby incorporated by reference in its entirety.
An anti-shake function of an electronic device such as a mobile phone can improve an image capturing quality of a camera module in use. When an anti-shake assembly realizes the anti-shake function by regulating a relative position relationship between a lens and an imaging sensor, an imaging effect of an edge of an image and an overall image capturing quality of the camera module will be reduced. Nevertheless, an anti-shake manner that takes both the imaging effect and the anti-shake effect into account needs to improve the anti-shake assembly, which causes an excessive occupation of an inner space of the electronic device.
The disclosure relates generally to a field of electronic technologies, and more particularly to a camera module and an electronic device.
According to a first aspect of the present disclosure, a camera module is provided, and includes a fixed bracket, a camera body and an anti-shake assembly. The camera body includes a lens and an imaging sensor corresponding to the lens in terms of positions. The camera body is provided with a movable connecting member on an external side surface of the camera body arranged along a circumferential direction of the lens, the fixed bracket is provided with a movable fitting member corresponding to the movable connecting member in terms of positions, and the movable fitting member is movably connected with the movable connecting member.
The anti-shake assembly includes a space attitude sensor and a driving module electrically connected with the space attitude sensor. The driving module is configured to be fitted with the camera body and to drive the camera body to perform an anti-shake motion relative to the fixed bracket according to shaking information obtained by the space attitude sensor.
According to a second aspect of the present disclosure, an electronic device is provided. The electronic device includes a device body and a camera module. The camera module is assembled to the device body. The camera module includes a fixed bracket, a camera body and an anti-shake assembly. The fixed bracket is assembled and fitted with the fixed member of the device body. The camera body includes a lens and an imaging sensor corresponding to the lens in terms of positions. The camera body is provided with a movable connecting member on an external side surface of the camera body arranged along a circumferential direction of the lens, the fixed bracket is provided with a movable fitting member corresponding to the movable connecting member in terms of positions, and the movable fitting member is movably connected with the movable connecting member. The anti-shake assembly includes a space attitude sensor and a driving module electrically connected with the space attitude sensor. The driving module is configured to be fitted with the camera body and to drive the camera body to perform an anti-shake motion relative to the fixed bracket according to shaking information obtained by the space attitude sensor.
It should be understood that the above general description and the detailed description below are merely used to explain the present disclosure, and cannot be construed as a limitation to the present disclosure.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the present disclosure as recited in the appended claims.
Since a current working position of the camera body 11 changes with respect to an original working position during shaking of the camera module 1, the imaging effect of the camera body 11 will be affected. Therefore, the anti-shake motion of the camera body 11 with respect to the fixed bracket 12 means a compensation motion in which a posture of the camera body 11 with respect to the fixed bracket 12 is regulated according to the overall shaking information of the camera module 1, so as to maintain the current working position of the camera body 11 in the original working position.
It should be noted that the space attitude sensor 131 may be a gyroscope or other devices for sensing a space attitude of the camera module 1, which is not limited in the present disclosure. The space attitude sensor 131 may be arranged to the fixed bracket 12, or the camera module 1 or other fixed parts of the electronic device 2 assembled with the camera module 1, so as to sense the overall shaking information of the camera module 1. The present disclosure does not limit an arrangement position of the space attitude sensor 131.
When the space attitude sensor 131 of the anti-shake assembly 13 senses the shaking information, the driving module 132 is controlled to be fitted with the camera body 11 and to drive the camera body 11 to perform the anti-shake motion relative to the fixed bracket 12. Since the lens 111 and the imaging sensor 112 of the camera body 11 perform the anti-shake motion relative to the fixed bracket 12 as a whole, an influence of the change of the relative position relationship between the lens 111 and the imaging sensor 112 on the image quality is avoided. Additionally, in the camera module 1, the movable connecting member 114 on the external side surface 113 of the camera body 11 may be used to be movably connected with the movable fitting member 121 on the fixed bracket 12, thereby reducing a structure size and a space occupation of the camera body 11 in a thickness direction.
In the above embodiment, at least two movable connecting members 114 may be provided on the external side surface 113 of the camera body 11, which is not limited in the present disclosure. When at least two movable connecting members 114 are arranged on the external side surface 113 of the camera body 11, the stability of the fit between the camera body 11 and the fixed bracket 12 is increased by improving the number and the arrangement manner of the movable connecting members 114. An exemplary description of the arrangement manner of the movable connecting member 114 will be described as follows.
In an embodiment, as illustrated in
In another embodiment, as illustrated in
As illustrated in
Alternatively, as illustrated in
In the above embodiments, one of the movable connecting member 114 and the movable fitting member 121 may be a guide wheel, and the other one thereof may be an arc-shaped guide rail, so as to drive the camera body 11 to generate the anti-shake motion around an optical axis of the lens 111 with respect to the fixed bracket 12 through a rolling of the guide wheel relative to the arc-shaped guide rail.
Alternatively, one of the movable connecting member 114 and the movable fitting member 121 is a sliding member, and the other one thereof is an arc-shaped slide rail. An arc center of the arc-shaped slide rail coincides with an optical axis of the lens, and the sliding member is slidably fitted with the arc-shaped slide rail. The sliding member may be a slide block structure matched with a cross-section shape of the arc-shaped slide rail. When the slide block slides in the arc-shaped slide rail, the slide block may drive the camera body 11 to generate the corresponding anti-shake motion around the optical axis of the lens 111 with respect to the fixed bracket 12.
The arc center of the arc-shaped guide rail coincides with the optical axis of the lens 111, such that the anti-shake motion of the camera body 11 is conducted around the optical axis of the lens 111, which facilitates the calculation and control of a motion track and helps to improve an anti-shake effect of the camera body 11.
For example, as illustrated in
Further, the anti-shake assembly 13 further includes a feedback module 133 electrically connected with the space attitude sensor 131, and the feedback module 133 includes a Hall sensor (not marked) and a controller (not marked) electrically connected with the Hall sensor. The feedback module 133 is arranged to the fixed bracket 12 or in other fixed positions inside the electronic device 2, which is not limited in the present disclosure. The camera body 11 further includes a magnetic field generator 116, and the Hall sensor corresponds to the magnetic field generator 116 in terms of positions. When the camera body 11 is controlled to perform the anti-shake motion according to the shaking information obtained by the space attitude sensor 131, a relative position relationship between the magnetic field generator 116 arranged on the camera body 11 and the Hall sensor changes. The Hall sensor converts a current position of the magnetic field generator 116 and the camera body 11 into an electrical signal and feeds it back to the controller. The controller compares the above current position with an expected position and sends a feedback control signal to the driving module 132, such that the anti-shake motion of the camera body 11 is tracked and has an error compensation, thereby improving the anti-shake effect of the camera module 1.
It should be noted that the driving module 132 may be at least one of an electromagnetic force driving assembly and a shape-memory alloy, or a driving module 132 based on other principles, which is not limited in the present disclosure. The electromagnetic force driving assembly pushes the camera body 11 to perform the anti-shake motion through an electromagnetic force, while the shape-memory alloy pushes the camera body 11 to perform the anti-shake motion via a current passing through a wire body to raise its temperature, and hence to result in a structure change of the shape-memory alloy.
When the electromagnetic force driving assembly pushes the camera body 11 to perform the anti-shake motion through the electromagnetic force, as illustrated in
For example, the fixed bracket 12 is a door-frame structure matched with the external side surface 113 of the camera body 11, the movable connecting members 114 are provided on the left side surface 1131 and the right side surface 1132 of the camera body 11 symmetrically, and the movable fitting members 121 are correspondingly arranged on the left side and the right side of the door-frame structure. In this case, the magnetic member 1322 may be arranged on the top side surface 1133 of the camera body 11, and the driving coil 1321 is correspondingly arranged to a top of the fixed bracket 12 of the door type, so as to avoid structure and function interferences between the magnetic member 1322, the driving coil 1321 and the movable connecting member 114, the movable fitting member 121, and also to allow the magnetic member 1322 between the two movable connecting members 114 to provide a stable pushing force for the camera body 11.
The present disclosure further proposes an electronic device 2, as illustrated in
It should be noted that the electronic device 2 may be a mobile phone, a tablet computer, a vehicle terminal or a medical terminal, etc., which is not limited in the present disclosure.
The camera module 1 is provided with the camera body 11 and the fixed bracket 12, and the movable connecting member 114 is provided on the external side surface 113 of the camera body 11 arranged along the circumferential direction of the lens 111, such that the movable connecting member 114 is movably connected with the movable connecting member 121 on the fixed bracket 12. When the space attitude sensor 131 of the anti-shake assembly 13 senses the shaking information, the driving module 132 is controlled to be fitted with the camera body 11 and to drive the camera body 11 to perform the anti-shake motion relative to the fixed bracket 12. Since the lens 111 and the imaging sensor 112 of the camera body 11 perform the anti-shake motion relative to the fixed bracket 12 as a whole, the influence of the change of the relative position relationship between the lens 111 and the imaging sensor 112 on the image quality is avoided. In addition, in the camera module 1, the movable connecting member 114 on the external side surface 113 of the camera body 11 may be used to be movably connected with the movable fitting member 121 on the fixed bracket 12, so as to reduce a structure size and a space occupation of the camera body 11 in a thickness direction, thus facilitating improvements of the lightness and thinness of the electronic device 2.
