In the related art, as shown in fig. 1, when the camera module is designed to be anti-shake, the pan/tilt head stand 200 is connected to the housing 500 of the electronic device, the camera 100 is rotatably disposed on the pan/tilt head stand 200, and the pan/tilt head stand 200 is disposed coaxially with the light-passing port 51 of the electronic device.

In order to solve the above problem, a camera module and an electronic apparatus according to an embodiment of the present application are described below with reference to fig. 2 to 8.

As shown in fig. 2, 3 and 4, a camera module according to some embodiments of the present application includes: camera head 100, pan-tilt support 200, shape memory structure 300 and drive assembly 400.

The camera 100 is movably arranged on the holder bracket 200, and the holder bracket 200 is connected with the shape memory structure 300; the actuation assembly 400 is coupled to the shape memory structure 300 to actuate the shape memory structure 300 from the first state to the second state, or from the second state to the first state.

With the shape memory structure 300 in the first state, the shape memory structure 300 is separated from the camera head 100; when the shape memory structure 300 is in the second state, the shape memory structure 300 abuts against the camera head 100.

Here, the camera 100 of the embodiment of the present application is movably disposed on the cradle head support 200, and it can be understood that the camera 100 can rotate relative to the cradle head support 200 to achieve the anti-shake purpose.

The shape memory structure 300 according to the embodiment of the present invention can be understood as a structure made of a material having a shape memory effect, such as a liquid crystal elastomer or a shape memory alloy. The shape memory structure 300 can be deformed by the energy such as heat, light, electricity, etc. transmitted from the driving assembly 400, and can restore the original state before the structure is deformed.

In practice, the original state of the shape memory structure 300 may be the first state, and the shape memory structure 300 is transformed from the first state to the second state by the energy delivered by the driving assembly 400. The original state of the shape memory structure 300 may also be the second state, from which the shape memory structure 300 is transformed into the first state by the energy delivered by the drive assembly 400.

Based on the above setting, when the module of making a video recording does not start shooting, accessible drive assembly 400 carried energy such as heat energy, light energy and electric energy to shape memory structure 300 for shape memory structure 300 forms the butt to camera 100 under the second state, makes camera 100's optical axis be close to the axis of cloud platform support 200 as far as possible, thereby reduces the offset of camera 100 for the axis of cloud platform support 200.

When installing the module of making a video recording on electronic equipment, because the axis of cloud platform support 200 leads to light mouthful 51 coaxial arrangement on with electronic equipment, when the optical axis of camera 100 and the axis of cloud platform support 200 were close to, camera 100 can reach coaxial arrangement state with leading to light mouthful 51 as far as possible to when the module of making a video recording does not start shooting, electronic equipment can reach better outward appearance effect.

Correspondingly, when the camera module starts shooting, the characteristic of deformation can be automatically recovered by the shape memory structure 300, so that the shape memory structure 300 is separated from the camera 100 in the first state, the camera 100 can be movably arranged on the holder support 200, the camera 100 can be controlled in an anti-shaking manner by the holder support 200 in the shooting process, and the shooting quality of the camera module on a target object is ensured.

In some embodiments, to control the coaxiality of the camera head 100 with respect to the pan/tilt head support 200, the shape memory structure 300 may be provided between the camera head 100 and the pan/tilt head support 200, and the shape memory structure 300 is adaptively arranged according to the camera head 100 such that the eccentric distance of the optical axis of the camera head 100 with respect to the central axis of the pan/tilt head support 200 is smaller than a preset value in the case where the shape memory structure 300 is in the second state.

In this embodiment, the shape memory structure 300 may be disposed around the camera 100, so that when the shape memory structure 300 is in the second state, the camera 100 and the cradle head 200 may reach a coaxial disposition state as much as possible under the driving of the shape memory structure 300, and at this time, the eccentric distance of the optical axis of the camera 100 relative to the central axis of the cradle head 200 is close to zero.

In some embodiments, in order to facilitate control of the coaxiality of the camera head 100 with respect to the head support 200 on the basis of the shape memory structure 300, the shape memory structure 300 of the embodiments of the present application comprises a plurality of shape memory members 310, the plurality of shape memory members 310 being arranged around the camera head 100 with respect to a central axis of the head support 200, a first end of each of the plurality of shape memory members 310 being connected to the head support 200, and a second end of each of the plurality of shape memory members 310 being adapted to abut against the head support 200 in the second state.

As shown in fig. 3, when the camera module starts to shoot, in order to perform anti-shake control on the camera head 100 through the pan-tilt-support 200, the present embodiment may control the driving assembly 400 not to transmit energy to the shape memory structure 300, so that each shape memory element 310 is in the first state. At this time, the second end of each shape memory member 310 is separated from the camera head 100, and the camera head 100 is movably disposed on the holder 200.

As shown in fig. 4, in order to ensure that the camera head 100 and the pan/tilt head support 200 are close to each other and even reach a coaxial arrangement state when the camera module does not start shooting, the present embodiment can control the driving assembly 400 to transmit energy to the shape memory structure 300, so that each of the shape memory members 310 is transformed from the first state to the second state. At this time, the second end of each shape memory member 310 abuts against the camera head 100, the camera head 100 and the pan/tilt head support 200 can achieve a coaxial arrangement state, and the camera head 100 can not move relative to the pan/tilt head support 200 any more.

In some embodiments, since the pan/tilt head stand 200 is generally configured as a trough-like structure and the camera head 100 is rotatably mounted within the pan/tilt head stand 200, to facilitate adjusting the coaxiality of the camera head 100 with respect to the pan/tilt head stand 200, the present embodiment locates the shape memory structure 300 within the pan/tilt head stand 200 and is connected to the inner sidewall of the pan/tilt head stand 200.

In some embodiments, as shown in fig. 2 and 8, the shape memory member 310 of the present embodiment includes: the electro-type shape memory member 331 and the driving unit 400 include a feeding portion 401.

The feeding unit 401 is electrically connected to the electro-type shape memory 331 to supply power to the electro-type shape memory 331. The electro-type shape memory 331 is changed between the first state and the second state according to the electric power supplied from the feeding part 401.

Specifically, power feeding unit 401 according to the embodiment of the present application may supply a voltage to electro-type shape memory member 331 so as to deform electro-type shape memory member 331 in an elongated manner.

When the camera module starts a shooting function, the power feeding unit 401 does not supply a voltage to the electro-type shape memory 331, and the electro-type shape memory 331 is in the first state. When the camera module starts a shooting function, the power feeding part 401 transmits voltage to the electric shape memory element 331, the electric shape memory element 331 is changed from the first state to the second state, and the electric shape memory element 331 is abutted to the camera 100, so that the camera 100 and the holder 200 can be ensured to be in a coaxial arrangement state.

Specifically, the electro-type shape memory member 331 of the present embodiment, which is prepared based on the electro-type liquid crystal elastomer 301 and the conductive structure 302, may be in a block shape, a sheet shape, or a tube shape, and is not particularly limited herein.

The electric field type liquid crystal elastic body 301 can be formed by compounding an inorganic conductive material or an organic conductive material by spin coating, swelling adsorption, physical doping and other methods.

Meanwhile, the conductive structure 302 may be a conductive layer containing carbon black or graphene, or may be a metal conductive structure containing copper wires or nickel chromium wires.

In some examples, the inorganic conductive material includes: any one of carbon fibers, carbon nanotubes, and graphene. The organic conductive material includes: any one of poly 3, 4-ethylenedioxythiophene, polystyrene sulfonate, and polyaniline.

In some examples, the materials of the electro-liquid crystal elastomer 301 include: 3, 6-dioxa-1, 8-octane dithiol, dipropylamine, pentaerythritol tetrakis (3-mercaptopropionate), and 1, 4-bis- [4- (3-acryloyloxypropoxy) benzoyloxy ] -2-methylbenzene.

1, 4-bis- [4- (3-acryloyloxypropoxy) benzoyloxy ] -2-methylbenzene is abbreviated as RM257, and the chemical structural formula is shown as (IV):

in some embodiments, as shown in fig. 8, the electro-type liquid crystal elastomer 301 according to the embodiment of the present application includes a first cross-linked layer 3011 and a second cross-linked layer 3012, and the conductive structure 302 is formed as a conductive layer sandwiched between the first cross-linked layer 3011 and the second cross-linked layer 3012.

In this embodiment, the first cross-linked layer 3011, the conductive layer, and the second cross-linked layer 3012 are combined into a whole to form a sheet-shaped composite layer structure. First crosslinked layer 3011 and second crosslinked layer 3012 may be provided in one layer or at least two layers, which is not particularly limited.

Meanwhile, the first cross-linked layer 3011 and the second cross-linked layer 3012 may both be films made of the material including the electro-liquid crystal elastomer 301, and the conductive layer may be a conductive carbon black layer, or may be a copper wire or a nickel-chromium wire, which is not specifically limited herein.

In some embodiments, the shape memory member 310 of embodiments of the present application includes: the thermotropic shape memory block 311, and the driving unit 400 include a heat generating component 411, and the heat generating component 411 is connected to the thermotropic shape memory block 311 to transfer heat energy to the thermotropic shape memory block 311. The thermotropic shape-memory block 311 is transitioned between the first state and the second state according to the heat energy delivered by the heat-generating component 411.

The heat generating component 411 shown in this embodiment may be an electric heating wire, a heat exchanging plate, or the like, which can provide a controllable temperature field to the thermotropic shape memory block 311. The thermotropic shape memory block 311 may be made of shape memory polyurethane, styrene-butadiene copolymer system shape memory resin, or the like.

In one example, when it is not necessary to photograph the target object, the driving assembly 400 may be controlled to stop operating such that the thermotropic shape memory block 311 is in a room temperature environment (e.g., a first temperature) at which the thermotropic shape memory block 311 reaches a first length. At this time, the thermotropic shape memory block 311 is in the second state, and it is ensured that the camera head 100 and the pan/tilt head support 200 are arranged coaxially as much as possible based on the thermotropic shape memory block 311.

When a target object needs to be photographed, the driving component 400 may provide a temperature stimulus to the thermotropic shape memory block 311, and when the thermotropic shape memory block 311 is heated from a first temperature to a second temperature, the thermotropic shape memory block 311 may be shortened from the first length to the second length and be in the first state. At this time, since the thermotropic shape memory block 311 is separated from the camera 100, the camera 100 is movably disposed on the pan/tilt/support frame 200, and the camera 100 can be controlled to be anti-shake based on the pan/tilt/support frame 200 during shooting.

In some examples, the thermotropic shape memory block 311 of the embodiments of the present application includes a thermotropic liquid crystal elastomer that is reversibly deformable around a liquid crystal transition temperature, the thermotropic liquid crystal elastomer having a cross-linked network including interconnected liquid crystal molecules, molecules containing allyl sulfide groups, flexible chains, and a cross-linking agent.

Specifically, the allyl sulfide group is a group which is sensitive to free radicals, can be kept stable in a solvent, cannot be subjected to dynamic exchange to change a network structure, and after the orientation is obtained, the orientation of the thermotropic liquid crystal elastomer cannot disappear in a swelling process.

Since the allyl sulfide group is sensitive only to free radicals, it remains stable in the absence of free radicals, and dynamic exchange occurs in the presence of free radicals. After the orientation of the thermotropic liquid crystal elastomer is fixed, the residual initiator is removed through swelling, repeated heating and cooling are carried out, or solvent stimulation is carried out, so that free radicals are not generated in the network structure, the allyl sulfide groups in the network structure can not be subjected to dynamic exchange, the orientation of the thermotropic liquid crystal elastomer can be kept all the time, and the thermotropic liquid crystal elastomer has stable reversible deformation near the liquid crystal transition temperature.

When the direction of the reversible deformation is along the axial direction (longitudinal direction) of the thermotropic liquid crystal elastic body, the reversible deformation range of the thermotropic shape memory block 311 is 30 to 60%.

As shown in fig. 5, after the thermotropic shape memory 311 is heated in a temperature field of 80 ℃ for 2 minutes, the thermotropic shape memory 311 assumes a contracted state, and the length of the thermotropic shape memory 311 is 8.02 mm.

As shown in FIG. 6, when thermotropic shape-memory block 311 was left at room temperature of 20℃, thermotropic shape-memory block 311 appeared in an elongated state and reached 11.70 mm. As described above, the thermotropic liquid crystal elastomer shown in the present example has reversible stretching deformation.

Here, the thermotropic liquid crystal elastomer shown in this embodiment can be used as a driving element of a liquid crystal elastomer, and can be applied to artificial muscles, blind displays, sensors, optical motors, microfluidic system valves, or intelligent response interface materials.

In some embodiments, as shown in fig. 7, the shape memory member 310 of embodiments of the present application includes: the holder comprises a light-induced shape memory reel 321 and a moving block 322, wherein the light-induced shape memory reel 321 is rotatably arranged on the holder 200, the side surface of the light-induced shape memory reel 321 is in friction contact with the surface of the moving block 322, and the moving block 322 is movably arranged on the holder 200.

Further, the driving assembly 400 includes an excitation light source 421, and the excitation light source 421 is used for transmitting excitation light to one side of the light-induced shape memory scroll 321. The light-induced shape memory scroll 321 is driven by the exciting light to rotate relative to the holder bracket 200; the moving block 322 is driven by the photo-induced shape memory spool 321 to move between a first position and a second position.

In the case where the moving block 322 is in the first position, the moving block 322 is separated from the camera head 100; when the moving block 322 is at the second position, the moving block 322 abuts against the camera 100.

It is understood that the light-induced shape memory roll 321 shown in this embodiment can be formed by winding a photosensitive shape memory film, and the photosensitive shape memory film can store a stretching strain energy in advance.

Under the irradiation of the exciting light, the stored strain energy is released by photo-thermal triggering, and the photosensitive shape memory film is subjected to photo-induced deformation, so that a great contraction force is generated on the side, facing the light source, of the photo-induced shape memory scroll 321, and the photo-induced shape memory scroll 321 can rotate continuously relative to the holder 200 due to the strong photo-induced contraction force.

Here, since the side surface of the photo shape memory reel 321 is in frictional contact with the surface of the moving block 322, when the photo shape memory reel 321 rotates, the moving block 322 moves between the first position and the second position by the frictional contact force between the photo shape memory reel 321 and the moving block 322.

When the camera module starts a shooting function, the present embodiment can control the moving block 322 to be in the first position, so that the moving block 322 is separated from the camera 100. When the camera module does not start the shooting function, the moving block 322 can be controlled to be located at the second position in the embodiment, so that the moving block 322 abuts against the camera 100, and the camera 100 and the holder 200 are ensured to be in a coaxial arrangement state as much as possible.

In some examples, as shown in fig. 7, the light-induced shape memory spool 321 of the embodiment of the present application includes a transparent drum 31 and an Al-Ce film 32, the transparent drum 31 is rotatably disposed on the holder 200, and the Al-Ce film 32 is wound on the transparent drum 31.

Specifically, the present embodiment can ensure that the light-induced shape memory spool 321 achieves good light acceptance while the Al — Ce thin film 32 is wound on the basis of the transparent roll 31 by providing the transparent roll 31. Meanwhile, since β -hydroxy ester bond can perform fast ester exchange reaction at high temperature by the action of catalyst and endow the material with excellent plasticity, the photosensitive shape memory film corresponding to the light-induced shape memory scroll 321 shown in this embodiment is specifically the Al-Ce film 32.

The excitation light source 421 of this embodiment can be an ultraviolet light source for emitting ultraviolet light to one side of the shape memory spool 321.
