Moreover, when the optical zoom motor is used on the smart phone, the use performance of a camera module of the smart phone can be improved, the overall thickness of the smart phone can be effectively reduced, and the problem that a rear camera of the smart phone protrudes outwards can be effectively solved, namely the problem that the rear camera of the smart phone protrudes out of a rear shell of the smart phone is solved.

It should be noted that the camera device in the present application can be applied to the field of miniature image photographing, such as tablet, computer, automotive electronics, and the like, in addition to the field of mobile phones.

As shown in fig. 1 to 10, the optical zoom motor of the present application includes a housing 10, a base 20, a lens support 30, a plurality of drive magnets 40, a plurality of drive coils 50, a plurality of side magnets 60, and a plurality of side coils 70. The base 20 is arranged below the casing 10 and forms an accommodating space with the casing 10, the casing 10 comprises a top wall 111 and a circumferential side wall 112, the top wall 111 is arranged opposite to the base 20, the top wall 111 is connected with the base 20 through the circumferential side wall 112, and one side wall of the circumferential side wall 112 is provided with an opening 113; the lens support 30 is movably arranged in the accommodating space; the driving magnet 40 is disposed on the lens support 30; a driving coil 50 provided on the base 20 and corresponding to the driving magnet 40, the driving coil 50 being energized to move the lens support 30 in a direction approaching or separating from the opening 113; at least one lateral magnet 60 is respectively arranged on a group of two oppositely arranged side walls of the circumferential side wall 112, and the lateral magnets 60 and the opening part 113 are respectively arranged on different side walls; the lateral coils 70 are provided on the lens support 30, and the plurality of lateral coils 70 are provided corresponding to the plurality of lateral magnets 60.

When the optical zoom motor with the above structure is used, because the opening part 113 is arranged on one side wall of the circumferential side wall 112 of the base 20, compared with the traditional optical zoom motor with the opening arranged at the top, when the optical zoom motor is arranged on the camera device, the whole thickness of the camera device can be reduced by changing the installation direction of the optical zoom motor, and meanwhile, the arrangement can also improve the variable-focus driving space range of the camera device parallel to the mobile phone direction, thereby creating favorable conditions for clearly capturing more distant scenes and obtaining more perfect image imaging effect. In addition, since the plurality of driving magnets 40, the plurality of driving coils 50, the plurality of side magnets 60, and the plurality of side coils 70 are respectively provided in the present application, the lens support body 30 can be driven to move in the accommodating space by the cooperation of the driving magnets 40 and the driving coils 50, thereby achieving the purpose of driving the optical zoom of the lens. The position of the lens support 30 relative to the opening 113 can be adjusted by driving the lens support 30 by the cooperation of the side magnets 60 and the side coils 70, thereby ensuring the anti-shake performance of the optical zoom motor. Therefore, the optical zoom purpose of driving the lens is achieved, the effective anti-shake function is achieved, the whole thickness of the camera device is effectively reduced by using the structure, the problem of limitation of the thickness of the mobile phone is solved, and the problems that the zoom range is narrow and the optical zoom capability is insufficient due to the fact that the camera is vertically placed on the surface of the mobile phone towards the outside conventionally are solved.

In the present application, the opening portions 113 may be provided on both of the pair of side walls of the housing 10 that face each other, and the side magnets 60 may be provided on the other pair of side walls that face each other.

It is noted that in the present application all movements of the lens holder 30 are in a direction parallel to the base 20. In addition, although the installation positions of the side coil 70 and the side magnet 60 are interchangeable in the present application, it should be noted that the fixing and electrical conduction manner of the side coil 70 after the interchange has certain complexity. In addition, the exchanged side magnets 60 may interfere with the position sensor 200 on the base 20 to some extent, and affect the feedback accuracy.

As shown in fig. 11, it should be noted that when the optical zoom motor in the present application is used in a mobile phone having a camera function, special attention needs to be paid to the installation direction of the optical zoom motor. When the optical zoom motor is used, the moving direction of the lens support 30 is parallel to the mobile phone rear case or the mobile phone screen when the lens support 30 is driven to focus. At this time, in order to ensure normal use of the camera module of the mobile phone, in an actual shooting process, the prism motor 100 is used together with the prism system while the optical zoom motor in the present application is used, that is, a driving system for lighting the prism at 45 degrees is added at the end of the lens. The prism camera is structurally characterized in that an incident surface of the prism motor 100 is parallel to a rear shell of the mobile phone or a screen of the mobile phone and can collect a target to be photographed, and a reflecting surface of the prism motor 100 is aligned with an opening 113 of the shield cover 11, namely a lens. The specific implementation way is that the lens is aligned along an optical axis parallel to the body, and then the light rays entering the camera are reflected to the optical zoom lens and the image sensor through the reflection of the prism, so that an equivalent focal length longer than that of the traditional camera in the vertical installation direction, namely towards the outside on the surface of the mobile phone, can be created.

Specifically, the lens support 30 is disposed above the base 20 in a floating manner, and a mounting gap is provided between the lens support 30 and the base 20. Since the lens support 30 is parallel to the base 20 during the movement, the friction between the lens support 30 and the base 20 can be effectively reduced by setting the mounting gap, and the service life of the optical zoom motor can be effectively ensured. Moreover, the influence of the base 20 on the movement of the lens support 30 can be reduced by the arrangement, and the movement of the lens support 30 is ensured to be more sensitive.

Specifically, the optical zoom motor further includes a plurality of suspension wires 80, one suspension wire 80 is correspondingly disposed at each corner of the portion of the base 20 located in the housing 10, and a plurality of corners of the lens support 30 are supported corresponding to the plurality of suspension wires 80, so that the lens support 30 is suspended. The suspension wire 80 is provided to realize electrical connection in the optical zoom motor, and since the lens support 30 is suspended above the base 20, the suspension wire 80 can ensure connection between the lens support 30 and the base 20, and the suspension wire 80 can limit movement of the lens support 30 to a certain extent and provide a supporting force for the lens support 30.

Specifically, the housing 10 includes a shield case 11, a frame 12, and a plurality of magnet back plates 13. The shield 11 has a top wall 111 and a circumferential side wall 112: the frame 12 is located in the accommodating space and connected to the top wall 111, and the lateral magnets 60 are located on one side of the frame 12 close to the base 20; the magnet back plate 13 is arranged corresponding to the lateral magnets 60, the magnet back plate 13 is located between the circumferential side wall 112 and the lateral magnets 60, and the magnet back plate 13 is made of a magnetic isolation material. By providing the shield cover 11, other components in the optical zoom motor can be effectively protected. And the side magnets 60 can be effectively fixed by providing the frame 12 and the plurality of magnet back plates 13. Moreover, the magnet back plate 13 can also play a role in magnetic isolation on the lateral magnets 60, so that the using effect of the lateral magnets 60 can be ensured, and the influence of the lateral magnets 60 on other components of the camera device can be reduced.

Optionally, the frame 12 is clamped to the side magnets 60.

Optionally, the magnet back plate 13 is clamped with the lateral magnets 60.

Optionally, the magnet back plate 13 is connected to the frame 12.

Specifically, at least three edges of the magnet back plate 13 are provided with flanges 131 to enclose a cavity for accommodating the lateral magnets 60, and at least one edge of the magnet back plate 13 is provided with a clamping protrusion 132, and the clamping protrusion 132 is matched with the clamping groove 121 of the frame 12; or the frame 12 has a bayonet 122 facing the base 20, and the edge of the side magnet 60 is clamped at the bayonet 122. Through setting up like this, can guarantee effectively that magnetite backplate 13 or frame 12 have guaranteed the stability of side direction magnetite 60 to the fixed effect of side direction magnetite 60 to when optics zoom motor receives striking or vibrations, can guarantee that relative rocking can not appear between side direction magnetite 60 and the shield cover 11.

Alternatively, the width of the flange 131 is equal to the thickness of the side magnet 60. By this arrangement, the side magnet 60 can be effectively protected, and a certain limit effect can be exerted on the movement of the lens support 30. The flange 131 can hold the side magnet 60 well. Further optionally, the outward extending end of the turned-over edge 131 is turned over upward to wrap the edge of the side magnet 60 to prevent the side magnet 60 from falling out.

Of course, the width of the turned-up edge 131 may be smaller or larger than the thickness of the side magnet 60 according to the actual use condition, but it is necessary to ensure the fixing effect of the magnet back plate 13 on the side magnet 60.
