Description

Technical Field

The invention relates to the field of camera devices using periscopic motors, in particular to a prism motor and an imaging system.

Background

In recent years, with market demands, a mobile phone camera has requirements of high pixel, large aperture and ultra-thin type for meeting new development trend.

The existing automatic focusing device is formed by accumulating the heights of a voice coil motor, a lens, an image sensor and a circuit board, and the bottleneck appears in the use of products in the prior art due to the improvement of mobile phone pixels and the requirement of thinner and thinner product heights. The overall optical height of the large aperture and high pixel lens is relatively high, so that the existing accumulated product height cannot meet the requirement of an ultrathin mobile phone body.

Due to the limitation of the thickness of the mobile phone, the camera of the mobile phone which is vertically placed conventionally (i.e. towards the outside on the surface of the mobile phone) has a small focal length and limited optical zooming capability. The periscopic camera is different from the vertical arrangement mode of the traditional lens, is transversely arranged in the mobile phone, is additionally provided with an optical conversion component, comprises an optical zoom motor, a lens group, a prism and the like, and realizes imaging by refracting light into the lens group by using a special optical prism, thereby achieving higher optical zoom times and enabling the lens to clearly shoot more distant scenes. The periscopic structure has good application prospect when being applied to the smart phone.

The invention aims to realize the special lighting path function of the periscope type motor by matching with the optical zoom motor through designing the prism motor as an optical conversion component. Because the periscopic motor can be transversely and parallelly arranged in the mobile phone, extremely favorable conditions are created for thinning the mobile phone body, and the effects of ultrathin mobile phone body and high-quality optical zoom imaging are finally realized.

Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present invention, unless specified to the contrary, use of the terms of orientation such as "upper, lower, top, bottom" or the like, generally refer to the orientation as shown in the drawings, or to the component itself in a vertical, perpendicular, or gravitational orientation; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

In order to solve the problem that prism motor performance is poor among the prior art, this application provides a prism motor and imaging system.

As shown in fig. 1 to 15, the prism motor in the present application includes a base 10, a prism support 20, a driving magnet 30, a driving coil 31, a PCB board 40, and a spring assembly 50. The base 10 has an accommodating space; the prism support body 20 is angularly adjustably arranged on the base 10, and at least a part of the prism support body 20 is positioned in the accommodating space; the driving magnets 30 and the driving coils 31 are located in the accommodating space and are arranged in a one-to-one correspondence manner, and when the driving magnets 30 are arranged on the prism support body 20, the driving coils 31 are arranged on the base 10; the PCB 40 is disposed on the base 10 and electrically connected to the driving coil 31; the spring assembly 50 is connected to the base 10 and the prism support 20, respectively, and the spring assembly 50 is parallel to the bottom surface of the base 10.

When the prism motor having the above-described structure is used, the prism support 20 is disposed on the base 10 so as to be inclined at an angle that can be adjusted, and thus the imaging angle of the prism 90 disposed on the prism support 20 can be adjusted. Since the driving magnets 30 and the driving coils 31 are provided at positions corresponding to the base 10 and the prism support body 20, respectively, the angle between the prism support body 20 and the base 10 can be adjusted by properly interacting the driving magnets 30 and the driving coils 31. Further, since the spring assembly 50 is further provided, the stability between the prism support 20 and the base 10 can be maintained by the spring assembly 50. Therefore, the service performance of the prism motor is effectively improved through the arrangement.

It should be noted that, by arranging the spring assemblies 50 in parallel, the prism motor can rotate the prism 90 by the prism support 20 with a small force by using the lever principle.

By such an arrangement, the position sensor can be arranged to protrude from the surface of the driving coil 31, so that the distance between the position sensor and the driving magnet 30 is shorter, the sensing between the position sensor and the driving magnet 30 is more sensitive, and the control of the prism support body 20 is more accurate.

In addition, in the present application, in order to ensure the inductive effect between the driving magnet 30 and the driving coil 31, the driving magnet 30 or the driving coil 31 disposed on the prism support 20 is disposed on the portion of the prism support 20 located in the angular accommodation space, and thus the inductive distance between the driving magnet 30 and the driving coil 31 can be effectively reduced, thereby ensuring the inductive effect between the driving magnet 30 and the driving coil 31.

It should be added that the prism support 20 has a magnet accommodating groove 32 for accommodating the driving magnet 30 on the side corresponding to the driving coil 31.

Specifically, the driving coil 31 is disposed on the base 10, a surface of the prism support 20 facing away from the accommodating space is a bearing surface for bearing the prism 90, and an included angle between a plane where the driving coil 31 is located and the bearing surface is greater than or equal to 43 degrees and less than or equal to 47 degrees.

Optionally, the adjustment angle range of the prism support 20 on the base 10 is less than 3 degrees.

Preferably, the adjustment angle range of the prism support 20 on the base 10 is less than 1.6 degrees.

In the present application, the purpose of the angle adjustment of the prism support 20 on the base 10 is mainly to adjust the angle of the prism 90, so that the optical anti-shake can be automatically realized. Namely, according to the shaking direction and degree of the camera, the position and the angle of the compensating mirror group are correspondingly adjusted, so that the light path is kept stable. Therefore, the periscopic motor is provided with the prism OIS optical anti-shake function, is not afraid of micro-shake, has good resistance to light path instability caused by hand shake and the like, and is greatly helpful for imaging.

Specifically, the base 10 includes an installation main board 11, the installation main board 11 is L-shaped to form an accommodating space, the driving coil 31 is disposed on the inner side wall of the installation main board 11, and the PCB board 40 is connected to the installation main board 11.

Specifically, the mounting main board 11 includes a first board section 111 and a second board section 112. The second plate section 112 has an installation notch 1121 for accommodating the driving coil 31, the first plate section 111 and the second plate section 112 are sequentially connected to form an accommodating space, and the first plate section 111 is perpendicular to the second plate section 112. Preferably, the mounting main plate 11 is provided as an integrally molded structure. Of course, the mounting board 11 may be provided as a separate structure, but when the mounting board 11 is provided as a separate structure, assembly of the mounting board 11 becomes difficult.

In one particular embodiment of the present application, the first plate section 111 is disposed in a horizontal direction, and the second plate section 112 is disposed in a vertical direction.

Specifically, the base 10 further includes two end plates 12 disposed opposite to each other, the two end plates 12 are respectively disposed on two sides of the mounting main plate 11 to form an accommodating space together, and the spring assembly 50 is connected to the end plates 12. In this way, the movement of the prism support 20 can be limited by the end plate 12, so that it can be effectively ensured that the prism support 20 is only angularly changed when the prism support 20 moves relative to the base 10.

Specifically, at least one plug board segment 113 protruding outward is further disposed on the mounting main board 11. It should be noted that the imaging system in the present application is a periscopic camera, and generally requires that the prism motor is used together with the optical zoom motor, so that the prism motor can be conveniently connected with other structures in the imaging system by arranging the socket plate section 113.

Specifically, a mounting groove 13 is reserved on a surface of the base 10 facing away from the accommodating space to fix the PCB 40. By such an arrangement, the PCB 40 can be mounted on the base 10 without protruding from the surface of the base 10, so that the overall structure of the prism motor can be more compact. In addition, by the arrangement, the PCB 40 can be limited and fixed to a certain extent, so that the PCB 40 and the base 10 cannot move relatively.

And, the mounting groove 13 is provided with a mounting protrusion 131, and the PCB 40 has a mounting hole 41 matched with the mounting protrusion 131, so that the fixing effect of the mounting groove 13 to the PCB 40 can be further ensured by matching the mounting protrusion 131 with the mounting hole 41.

Specifically, the PCB 40 has a first section 42 and a second section 43 connected to each other, the first section 42 is mounted on the first board section 111, the second section 43 is mounted on the second board section 112, and the first section 42 has a terminal pin on a portion extending outward of the base 10. In the present application, the prism motor is electrically connected to the outside through the terminal pins, and the driving coil 31 is electrically connected through the terminal pins and the PCB 40.

Specifically, an open groove 121 is formed on an inner wall of the end plate 12 facing the accommodating space, the prism support body 20 has an overlapping protrusion 21 engaged with the open groove 121, and a movable gap is formed between the overlapping protrusion 21 and the open groove 121. By this arrangement, it can be ensured that the overlapping protrusions 21 can rotate in the open grooves 121 during the rotation of the prism support body 20 relative to the base 10. In addition, the open groove 121 can limit the rotation angle of the prism support 20, thereby preventing the rotation angle of the prism support 20 from exceeding a predetermined value. In addition, by setting the movable gap, the prism support body 20 can be prevented from being relatively locked between the overlapping protrusion 21 and the opening groove 121 in the rotating process, so that the prism support body 20 cannot rotate relative to the base 10. It should be noted that, in the present application, the specific size of the movable gap is determined according to the size of the angle that the prism support 20 can rotate relative to the base 10.

Specifically, the surface of the overlapping protrusion 21 on the side away from the base 10 is parallel to the first plate section 111. By this arrangement, the stability of the movement of the prism support body 20 can be effectively ensured.

Optionally, the spring assembly 50 comprises a plurality of springs, and each end plate 12 is connected to the prism support 20 by at least one spring. By this arrangement, the connection between the prism support 20 and the base 10 can be secured by deformation of the spring pieces.

By providing the frame 70 and the housing 80, the base 10, the prism support 20, and the PCB 40 can be effectively protected from external impacts on the prism support 20 or the base 10 during the use of the prism motor.

Also, the terminal pins and a portion of the PCB board 40 protrude outward from the housing 80 in this application to enable electrical connection of the terminal pins.

Specifically, the frame 70 is provided with at least one bayonet 71, and the base 10 has a stop lug 14 matched with the bayonet 71. By so arranging, stability between the frame 70 and the base 10 can be effectively ensured.
