[0029] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0030] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0031] The camera, camera driving method, device and equipment provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0032] The camera provided in the embodiment of the present application may include: a shell, a lens, a motor, a filter, a photosensitive chip and a fixing unit; wherein the lens is located on the filter, the filter is located on the photosensitive chip, and the motor is used to drive the lens to move; the shell is located outside the lens, the motor, the filter, the photosensitive chip and the fixing unit; the fixing unit is used to fix the lens so that it does not move when the camera is not powered on, and to release the fixed lens when the camera is powered on.

[0033] like Figure 1 As shown, Figure 1 1 is a schematic diagram of the structure of a camera provided in an embodiment of the present application. The camera 100 may include: a circuit board 1, a lens 2, a motor 3, a filter 4, a photosensitive chip 5, a base 6 and a fixing unit 7. The motor 3 includes a motor housing 31, a coil 32, a magnet 33 and a carrier 34.

[0034] The circuit board 1 is used to provide electrical connection between the various components of the camera 100; the lens 2 is used to gather light; the filter 4 is used to filter non-visible light to improve the imaging quality; the photosensitive chip 5 receives light and converts the optical signal into an electrical signal; the base 6 is used to support the filter 4; the motor housing 31 is used to protect the internal structure of the motor 3; the coil 32 and the magnet 33 are used to drive the carrier 34 to move and then drive the lens 2 to move, and the carrier 34 is used to carry the magnet 33 and the lens 2.

[0035] The fixing unit 7 is used to fix the lens 2 so that it does not move when the camera 100 is not powered on.

[0036] It should be noted that in Figure 1 The housing of the camera is not shown.

[0037] In the embodiment of the present application, since the camera includes a fixing unit, when the camera is not powered on, the fixing unit can fix the lens of the camera so that it does not move. Thus, it is possible to avoid collision between the lens and the filter of the camera, prevent damage to the filter, and ensure the shooting function of the camera.

[0038] In some possible implementations of the embodiments of the present application, when the camera 100 is not powered on, one side of the fixing unit 7 is fixed to the motor housing 31, and the other side is fixed to the coil 32. The coil 32 and the magnet 33 are in contact with the fixing carrier 34 and do not move, thereby preventing the lens 2 carried on the carrier 34 from moving.

[0039] In some possible implementations of the embodiments of the present application, the fixing unit 7 may be fixed between the motor housing 31 and the coil 32 by adhesive.

[0040] In some possible implementations of the embodiments of the present application, the fixing unit 7 may be a power-on deformable elastic body. When the fixing unit 7 is powered on, the fixing unit 7 is deformed, i.e., its shape changes, so that the coil 32 is separated from the magnet 33, and the carrier 34 is no longer fixed, so that the carrier 34 moves, and then the lens 2 moves, and the camera 100 performs image acquisition. When the fixing unit 7 is not powered on, the shape of the fixing unit 7 is restored, so that the coil 32 and the magnet 33 contact and fix the carrier 34 without moving, so that the lens 2 carried on the carrier 34 does not move either.

[0041] The states of the fixed unit 7 when not powered on and powered on are respectively as follows: Figure 2 and Figure 3 shown. Figure 2 The figure shows the state of the fixing unit provided in the embodiment of the present application when it is not powered on. Figure 3 The figure shows the state of the fixing unit provided in the embodiment of the present application when it is powered on.

[0042] The fixing unit 7 is in a bent state when not powered on, and is in a straight state when powered on.

[0043] In some possible implementations of the embodiments of the present application, the electrically deformable elastic body in the embodiments of the present application may be a liquid crystal elastomer. The liquid crystal elastomer is an electroactive polymer that will produce a certain amount of deformation after being powered on. In the power-off (unpowered) state, the liquid crystals are arranged in a disorderly manner and the elastomer is bent; in the power-on (powered) state, the liquid crystals are arranged in an orderly manner and the elastomer is significantly stretched relative to the bent state.

[0044] In some possible implementations of the embodiments of the present application, the deformation of the electrically deformable elastic body is greater than the distance between the coil 32 and the magnet 33. That is, the deformation of the electrically deformable elastic body needs to be greater than the distance between the coil 32 and the magnet 33, so that the coil 32 and the magnet 33 can contact each other when the electrically deformable elastic body is not powered on. Otherwise, the coil 32 and the magnet 33 cannot contact each other when the electrically deformable elastic body is not powered on, and the carrier 34 cannot be fixed, that is, the lens 2 cannot be fixed.

[0045] Typically, the distance between the coil 32 and the magnet 33 is 0.15 millimeters (mm), and the deformation of the electrically deformable elastic body is greater than 0.15 mm.

[0046] In the embodiment of the present application, since the deformation of the electrically deformable elastic body is greater than the distance between the coil and the magnet, when the electrically deformable elastic body is not powered, the coil is in contact with the magnet and the carrier will not move due to the compression of the coil.

[0047] The states of the camera 100 when it is not powered on and when it is powered on are respectively as follows: Figure 4 and Figure 5 shown. Figure 4 The state of the camera provided in the embodiment of the present application when it is not powered on is shown. Figure 5 The figure shows the state of the camera provided in the embodiment of the present application when it is powered on.

[0048] When the camera 100 is not powered on, the fixing unit 7 is not powered on. At this time, the fixing unit 7 makes the coil 32 contact with the magnet 33, and the carrier 34 is squeezed by the magnet 33 and does not move. When the camera 100 is powered on, the fixing unit 7 is powered on. At this time, the fixing unit 7 separates the coil 32 from the magnet 33 and no longer fixes the carrier 34, so that the carrier 34 moves, thereby driving the lens 2 to move, and the camera 100 performs image acquisition.

[0049] Figure 6 : is a flow chart of a camera driving method provided in an embodiment of the present application. The camera driving method may include:

[0050] S601: Power on the camera provided in the embodiment of the present application;

[0051] S602: Control the fixing unit to release the fixed lens, so that the lens moves and the camera collects images.

[0052] The specific implementation of the above steps will be described in detail below.

[0053] In the embodiment of the present application, since the camera provided by the embodiment of the present application includes a fixing unit, when the camera is not powered on, the fixing unit can fix the lens so that it does not move, thereby preventing the lens from colliding with the filter of the camera, and not damaging the filter, thereby ensuring the shooting function of the camera. When the camera is powered on, the fixing unit releases the fixed lens, causing the lens to move, and the camera performs image acquisition.

[0054] In some possible implementations of the embodiments of the present application, in S601, after receiving an input for starting the camera, the camera is powered on. The input for starting the camera includes but is not limited to: clicking a "camera" control, or clicking a "scan" control, or clicking a "scan code" control, etc.

[0058] In the embodiment of the present application, when the camera is powered off, the fixing unit is powered off, at which time, the fixing unit is restored to its original shape, the coil contacts the magnet, and the fixed lens does not move. This can prevent the lens from colliding with the filter of the camera, and will not damage the filter, thus ensuring the camera's shooting function. When the camera is powered on, the fixing unit releases the fixed lens, causing the lens to move, and the camera performs image acquisition.

[0063] In the embodiment of the present application, since the camera provided by the embodiment of the present application includes a fixing unit, when the camera is not powered on, the fixing unit can fix the lens so that it does not move, thereby preventing the lens from colliding with the filter of the camera, and not damaging the filter, thereby ensuring the shooting function of the camera.

[0064] In some possible implementations of the embodiments of the present application, the control module 702 may be specifically used to:

[0065] The fixing unit is powered on so that the fixing unit changes shape when powered on, the coil of the motor is disconnected from the magnet, and the fixing lens is released.

[0066] In the embodiment of the present application, when the camera is powered on, the fixing unit is powered on, at which time the fixing unit releases the fixed lens, allowing the lens to move, and the camera performs image acquisition.
