The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

With the advancement of technology, electronic devices with cameras such as digital cameras, smart phones, tablet computers and notebook computers are more and more frequently used in people's daily life. When using electronic devices for shooting, in order to make the captured The scene is clearly imaged on the photosensitive element of the camera, and the focal length of the camera is generally adjusted automatically or manually by the user.

In the related art, the camera usually includes a voice coil motor (Voice Coil Actuator/Voice Coil Motor), which can adjust the distance between the lens and the photosensitive element in the camera, so that the focal length of the camera meets the needs of users. However, the voice coil motor has a relatively complex structure and a large volume, which increases the production cost of the camera and increases the volume of the camera.

In order to solve the above problems, the technical solutions provided by the embodiments of the present disclosure provide a camera module, the camera module includes a lens, a lens mount and a photosensitive element, wherein the lens is connected to the mirror mount, the photosensitive element is connected to the mirror mount, The main optical axis of the lens is perpendicular to the photosensitive element, wherein the photosensitive element is used to generate an image according to the light passing through the lens, and the mirror base is made of shape memory alloy, which is used to shrink when the mirror base is energized to drive the lens to move along the main optical axis. The direction is close to the photosensitive element, or when the lens base is powered off, it returns to its original shape to drive the lens away from the photosensitive element along the direction of the main optical axis, so as to achieve the purpose of adjusting the distance between the lens and the photosensitive element, so that the camera module can be used without a voice coil The focal length during shooting is adjusted on the premise of the motor, and the size of the camera module is reduced.

An embodiment of the present disclosure provides a camera module, which is applied to an electronic device, where the electronic device may include a smart terminal, a tablet computer, a smart wearable device, and the like. As shown in Figure 1a, the camera module 100 includes a lens 101, a mirror mount 102 and a photosensitive element 103, wherein the lens 101 is connected to the mirror mount 102, the photosensitive element 103 is connected to the mirror mount 102, and the main optical axis of the lens 101 is perpendicular to photosensitive element 103 .

The photosensitive element 103 is configured to generate an image according to the light transmitted by the lens 101 .

The mirror base 102 is made of shape memory alloy, which is used to shrink when the mirror base 102 is energized to drive the lens 101 close to the photosensitive element 103 along the direction of the main optical axis, or to restore the original shape when the mirror base 102 is powered off to drive the lens 101 to move along the main optical axis. The direction of the optical axis is away from the photosensitive element 103 .

Exemplarily, the lens and the mirror base are connected through threaded fit. The photosensitive element can be directly connected to the mirror base, or can be connected to the mirror base through an intermediate structure such as a substrate.

The photosensitive element can be connected with the processor in the electronic device to convert the light signal corresponding to the light transmitted by the lens into a target signal, wherein the target signal can be an analog signal or a digital signal, so that the processor can instruct the storage in the electronic device The device stores the target signal to save the image captured by the electronic device through the camera assembly, or instructs the display screen in the electronic device to display the image captured by the electronic device through the camera assembly according to the target signal.

The mirror mount made of shape memory alloy has the ability to recover from deformation. Among them, the reason why the shape memory alloy has the ability to recover from deformation is due to the thermoelastic martensitic transformation that occurs inside the material during the deformation process. There are two phases in the shape memory alloy: high temperature phase austenite phase and low temperature phase martensite phase. According to different thermal loading conditions, shape memory alloys exhibit two properties. By energizing the lens base to increase its temperature, the shape memory alloy changes from martensite to austenite, so that the lens base shrinks to drive the lens close to the photosensitive element along the direction of the main optical axis. When the base is powered off, the shape memory alloy changes from austenite to martensite, and the lens base returns to its original state, so that the lens base is stretched to drive the lens away from the photosensitive element along the direction of the main optical axis.

For example, the inherent shape of the mirror base after deformation is a contracted state, and the inherent shape of the mirror base before deformation is the original state. When the mirror base is in the contracted state, the first distance between the lens and the photosensitive element is smaller than when the mirror base is in the original state. second distance. When the mirror base is not energized, its initial state is the inherent shape before deformation, that is, the original state. By energizing the mirror base, the temperature of the mirror base can be increased. When the mirror base made of shape memory alloy is heated above the final temperature , the low-temperature martensite in the mirror holder reverses into the high-temperature austenitic phase, so that the mirror holder shrinks from the original shape before deformation to the original shape after deformation, even if the mirror holder changes from the original state to the contracted state, so that the mirror holder The contraction is generated to drive the lens closer to the photosensitive element along the direction of the main optical axis. When the mirror base is powered off, the temperature of the mirror base drops. When the temperature of the mirror base drops below the final temperature, the mirror base returns to the martensitic shape through the release of internal elastic energy, so that the mirror base changes from the inherent shape after deformation. Return to the inherent shape before deformation, that is, the lens base returns to the original state from the contracted state, so that the lens base is stretched to drive the lens away from the photosensitive element along the direction of the main optical axis.

In the technical solution provided by the embodiments of the present disclosure, a camera module is provided. The camera module includes a lens, a lens mount, and a photosensitive element, wherein the lens is connected to the mirror mount, the photosensitive element is connected to the mirror mount, and the main optical axis of the lens Perpendicular to the photosensitive element, wherein the photosensitive element is used to generate images according to the light transmitted by the lens, and the lens base is made of shape memory alloy, which is used to shrink when the lens base is powered on to drive the lens close to the photosensitive element along the direction of the main optical axis, Or when the lens base is powered off, it can be restored to its original shape to drive the lens away from the photosensitive element along the direction of the main optical axis, so as to achieve the purpose of adjusting the distance between the lens and the photosensitive element, so that the camera module can be adjusted without a voice coil motor The focal length when shooting, and the volume of the camera module is reduced, which improves the user's photographing experience.

In one embodiment, as shown in FIG. 1 b , the camera module 100 further includes a temperature control element 104 connected to the mirror base 102 .

The temperature control element is used to adjust the temperature of the mirror base, so that the mirror base shrinks when the temperature of the mirror base is adjusted to the second temperature to drive the lens to approach the photosensitive element along the direction of the main optical axis, or to make the mirror base at the temperature of the mirror base When adjusted from the second temperature to the first temperature, the lens is stretched to drive the lens away from the photosensitive element along the direction of the main optical axis, the first temperature is lower than the end temperature of the shape memory alloy, and the second temperature is greater than the end temperature of the shape memory alloy.

Exemplarily, the temperature control element may be an electric heating wire or an electric heating sheet, such as a resistance wire made of iron-chromium-aluminum alloy or nickel-chromium alloy, and a ceramic heating sheet. The temperature control element can be electrically connected to a processor in the electronic device. When the temperature control element receives the temperature increase command sent by the processor, the temperature control element responds to the temperature increase command to heat the mirror base to ensure that the temperature of the mirror base is raised to a second temperature, wherein the second temperature is greater than the shape The end temperature of the memory alloy makes the lens base shrink to drive the lens close to the photosensitive element along the direction of the main optical axis; when the temperature control element receives the temperature stop raising instruction sent by the processor, the temperature control element responds to the temperature stop raising instruction and stops The lens base is heated to ensure that the temperature of the lens base is adjusted from the second temperature to the first temperature lower than the end temperature of the shape memory alloy, so that the lens base is stretched to drive the lens away from the photosensitive element along the direction of the main optical axis.

When controlling the camera module to zoom, the temperature of the lens base needs to be increased by energizing the lens base. When the ambient temperature of the camera module is low, the time required for the temperature of the lens base to be raised above the final temperature may be too long , by setting the temperature control element in the camera to adjust the temperature of the lens base, the speed of raising the temperature of the lens base can be accelerated, and the time required for the temperature of the lens base to be raised above the final temperature can be reduced, so that in the environment of the camera module Speed up the zoom speed of the camera module when the temperature is low.

The photosensitive element and the mirror base can be connected to the substrate through a non-detachable fixing structure, for example, the mirror base is bonded to the substrate through an adhesive, or can be connected to the substrate through a detachable fixing structure.

When the photosensitive element is connected to the lens base through the substrate, it can reduce the interference of the lens base to the photosensitive element when its temperature rises or shrinks, thereby reducing the interference when taking images through the camera module and improving user experience.

In one embodiment, as shown in FIG. 1d , the camera module 100 further includes a temperature sensing element 106 connected to the substrate 105 .

The temperature sensing element 106 is used to obtain the temperature of the mirror base 102 .

By setting the temperature sensing element connected to the substrate in the camera module, the temperature of the lens base can be obtained, so that the current through the lens base can be determined according to the temperature of the lens base, so as to reduce the power consumption as much as possible. Under the premise of electricity, the temperature of the mirror base is raised above the final temperature.
