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 application, where the contrary is not intended, the use of directional words such as "upper, lower, top and bottom" is generally with respect to the orientation shown in the drawings, or with respect to the component itself in the vertical, perpendicular or gravitational direction; 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.

Also, the imaging system in the present application includes a prism motor described below.

It should be noted that the periscopic motor of the imaging system in the present application can be used not only in terminal electronic products such as smart phones, but also in miniature image shooting fields such as tablet computers and automotive electronics.

As shown in fig. 2 to 13, the prism motor of the present application includes a base 10, a prism support 20, two sets of driving magnets 30, and two sets of driving coils 40 and a PCB 50. The base 10 has an angular accommodation space 11; the prism support body 20 is obliquely arranged on the base 10 with an adjustable angle, and at least one part of the prism support body 20 is positioned in the angular accommodating space 11; the two groups of driving magnets 30 and the two groups of driving coils 40 are positioned in the angular accommodating space 11 and are arranged in a one-to-one correspondence manner, when the driving magnets 30 are arranged on the prism support body 20, the driving coils 40 are arranged on the base 10, and the two groups of driving coils 40 or the two groups of driving magnets 30 are respectively positioned on different inner surfaces of the base 10; the PCB board 50 is disposed on the base 10 and electrically connected to the driving coil 40.

When the prism motor having the above-described structure is used, since the prism support 20 is provided on the base 10 at an angle-adjustable inclination, the imaging angle of the prism 200 provided on the prism support 20 can be adjusted. And the driving coils 40 and the driving magnets 30 are respectively and correspondingly arranged at the positions of the base 10 and the prism support body 20, and the two groups of driving coils 40 or the two groups of driving magnets 30 are respectively positioned on different inner surfaces of the base 10, so that the angle adjustment between the prism support body 20 and the base 10 can be realized reasonably through the interaction of the two groups of driving magnets 30 and the driving coils 40. Therefore, the service performance of the prism motor is effectively improved through the arrangement.

Further, it should be noted that, in the present application, in order to ensure the inductive effect between the driving magnet 30 and the driving coil 40, the driving magnet 30 or the driving coil 40 disposed on the prism support 20 is disposed on the portion of the prism support 20 located in the angular accommodation space 11, and thus the inductive distance between the driving magnet 30 and the driving coil 40 can be effectively reduced, thereby ensuring the inductive effect between the driving magnet 30 and the driving coil 40.

Specifically, as shown in fig. 4 to 6, the driving coils 40 are disposed on the base 10, a surface of the prism support 20 away from the angular accommodation space 11 is a bearing surface 21 for bearing the prism 200, and an included angle between a plane of any one of the driving coils 40 and the bearing surface 21 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 200, 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.

In one embodiment of the present application, as shown in fig. 6 and 10, the driving coil 40 is disposed on the base 10, and the driving magnet 30 is disposed on the prism support 20, so that the driving coil 40 can be more conveniently connected to the PCB 50, thereby ensuring the stability of the electrical connection between the PCB 50 and the driving coil 40.

It should be noted that the drive coil 40 is only accommodated in the first mounting notch 123 and the second mounting notch 124 of the base 10 in the present application, and an integral connection type design is adopted between the drive coil 40 and the PCB board 50 in a preferred embodiment.

Further, although the prism support 20 is provided on the base 10 so as to be angularly adjustable in the present application, the prism support 20 is generally adjusted only within a range of plus or minus 1.5 degrees when the prism support 20 is angularly adjusted. In addition, the gap between the prism support 20 and the base 10 can be effectively reduced.

Specifically, the base 10 includes a mounting main board 12, the mounting main board 12 is L-shaped to form an angular accommodation space 11, two sets of driving coils 40 are respectively mounted on two planes perpendicular to each other of the mounting main board 12, and the PCB board 50 is connected to the mounting main board 12. With this arrangement, when the two driving coils 40 respectively act on the two driving magnets 30, acting forces are respectively generated in two mutually perpendicular directions, so that the prism support body 20 is turned over with respect to the base 10 by the action of the two mutually perpendicular acting forces.

It should also be noted that in one embodiment of the present application, the current directions of the two groups of driving coils 40 after being energized are identical.

Specifically, the mounting main board 12 includes a first board section 121 and a second board section 122. The first plate segment 121 has a first mounting notch 123 that receives the drive coil 40; the second plate section 122 has a second mounting notch 124 for accommodating the driving coil 40, the first plate section 121 and the second plate section 122 are sequentially connected to form an angular accommodating space 11, and the first plate section 121 is perpendicular to the second plate section 122. Preferably, the mounting main panel 12 is provided as an integrally formed structure. Of course, the mounting main board 12 may be provided as a separate body structure, but when the mounting main board 12 is provided as a separate body structure, assembly of the mounting main board 12 becomes difficult.

Specifically, the base 10 further includes two end plates 13 disposed opposite to each other, the two end plates 13 are respectively disposed at two sides of the mounting main plate 12 to jointly form the angular accommodation space 11, the end plates 13 have overlapping inclined surfaces 131, and two ends of the prism support 20 are overlapped on the overlapping inclined surfaces 131. In this way, the movement of the prism support 20 can be limited by the end plate 13, 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, the mounting main board 12 is further provided with at least one plug board segment 14 extending outwards. It should be noted that when the imaging system in the present application is a periscopic camera, the prism motor is usually required to be used together with the optical zoom motor 90, so that the prism motor can be conveniently connected with other structures in the imaging system by providing the socket plate section 14.

Specifically, the surface of the base 10 facing away from the angular accommodation space 11 is reserved with an installation groove 15 for fixing the PCB 50. By such an arrangement, the PCB 50 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 50 can be limited and fixed to a certain extent, so that the PCB 50 and the base 10 cannot move relatively.

Moreover, it should be noted that, in the present application, the mounting groove 15 has a mounting protrusion 151 therein, and the PCB 50 is provided with a mounting hole 54 matching with the mounting protrusion 151, so that the mounting effect of the mounting groove 15 on the PCB 50 can be further ensured by matching the mounting protrusion 151 with the mounting hole 54.

Specifically, as shown in fig. 3, the PCB 50 has a first section 51 and a second section 52 connected to each other, the first section 51 is mounted on the first board section 121, the second section 52 is mounted on the second board section 122, the first section 51 and the second section 52 are electrically connected to different driving coils 40, and the first section 51 extends to the outside of the base 10 and has a terminal pin 53 on the portion extending out. It should be noted that in the present application, the prism motor is electrically connected to the outside through the terminal pins 53, and the driving coils 40 are electrically connected through the terminal pins 53 and the PCB board 50, that is, the terminal pins 53 corresponding to different driving coils 40 are different, and the driving coil 40 fixed on the first board segment 121 is connected to the first segment 51 and communicated with the corresponding terminal pins 53, while the driving coil 40 fixed on the second board segment 122 is connected to the second segment 52 and communicated with the corresponding terminal pins 53.

In one embodiment of the present application, the first segment 51 is further provided with a position sensor 511, and the driving coil 40 connected to the first segment 51 is sleeved on the position sensor 511. It should also be noted that after assembly is complete, a certain gap is required between the drive coil 40 and the position sensor 511 to ensure that the drive coil 40 and the position sensor 511 do not come into contact with each other.

Specifically, as shown in fig. 5 and 7, an open groove 132 is formed on an inner wall of the end plate 13 facing the angular accommodation space 11, the prism support body 20 has an overlapping protrusion 22 engaged with the open groove 132, and a movable gap is formed between the overlapping protrusion 22 and the open groove 132. By this arrangement, it is ensured that the overlapping protrusions 22 can rotate in the open grooves 132 during the rotation of the prism support body 20 relative to the base 10. Further, the open groove 132 can limit the rotation angle of the prism support body 20, thereby preventing the rotation angle of the prism support body 20 from exceeding a predetermined value. In addition, by setting the movable gap, it is also able to prevent the prism support 20 from being relatively locked between the overlapping protrusion 22 and the opening groove 132 during the rotation process, so that the prism support 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, as shown in fig. 9 and 11, the prism motor further includes a plurality of reeds 60, and each of the end plates 13 is connected to the prism support body 20 through at least one of the reeds 60. Since there is a play between the open groove 132 and the overlapping protrusion 22, the connection between the prism support 20 and the base 10 can be maintained by the spring 60 by providing the spring 60. Also, with this arrangement, when the prism support 20 and the base 10 are relatively rotated, the connection between the base 10 and the prism support 20 can be secured by the deformation of the spring 60.

It should also be noted that the spring 60 can also limit the position of the prism support 20.

In one embodiment of the present application, there are two of the leaves 60.

In the present application, the base 10 and the prism support 20 are respectively provided with the heat staking posts 80, and the spring pieces 60 are connected to the base 10 and the prism support 20 by the heat staking posts 80. Preferably, the spring plate 60 of the present application is provided with welding holes 61 respectively matching with the hot riveting columns 80 on the base 10 and the prism support 20.

Specifically, as shown in fig. 12, the prism motor further includes a frame 70, and at least a portion of the frame 70 overlaps the end plate 13 and shields the spring 60 and the overlapping protrusion 22.

Specifically, as shown in fig. 12 and 13, the prism motor further includes a frame 70 and a housing 100. At least a portion of the frame 70 overlaps the base 10 to retain the prism support 20 between the base 10 and the frame 70; the housing 100 is disposed around the periphery of the base 10 and is snapped into engagement with the base 10 and/or the frame 70.

By providing the frame 70 and the housing 100, the base 10, the prism support 20, and the PCB 50 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 53 and a portion of the PCB board 50 protrude outward from the housing 100 in this application to achieve electrical connection of the terminal pins 53.

Specifically, the frame 70 is provided with at least one bayonet 71, the housing 100 is a metal plate-shaped member and is formed by bending, and the housing 100 has a bayonet 110 which is folded toward the bayonet 71. In the present application, the prism support 20 is assembled with the base 10, and is assembled with the frame 70 after the assembly is completed, and finally the housing 100 is mounted. Through setting up like this, when installing shell 100, can stretch into bayonet 71 through buckle 110 and inside the equipment of accomplishing shell 100 to can also guarantee the stability between shell 100 and the frame 70 through setting up like this, thereby guarantee can not appear rocking relatively between shell 100 and the frame 70 in the use of prism motor.

And, in order to ensure easy assembling between the frame 70 and the housing 100. The inner space of the bayonet 71 may be larger than the volume of the bayonet 110.

It should be noted that, in the present application, there is a clamping structure between the frame 70 and the casing 100 to ensure the stability of the connection between the frame 70 and the casing 100.

The shell 100 comprises first section 120, the second section 130 and the third section 140 of folding that connects in order, and first section 120 and the third section 140 of folding are perpendicular to the second respectively and fold section 130 and lie in the second and fold same one end of section 130, wherein: one side edge of the first folding section 120 and one side edge of the third folding section 140 are both provided with a clamping interface 150, and the frame 70 is provided with a clamping convex block 72 matched with the clamping interface 150; the other side edge of the first folding section 120 and the other side edge of the third folding section 140 are both provided with a clamping groove 160, and the frame 70 is provided with a clamping protrusion 73 matched with the clamping groove 160; the first folding section 120 and the third folding section 140 are provided with positioning holes 170, and the frame 70 is provided with positioning columns 74 matched with the positioning holes 170; the second folding section 130 has a limiting groove 180, and the frame 70 has a limiting edge 75 engaged with the limiting groove 180.

By this arrangement, the limit of the rotation of the prism support body 20 can be achieved by the cooperation of the first contact stop surface 125 and the first stop surface 23 and the cooperation of the second contact stop surface 126 and the second stop surface 24. Furthermore, it should be noted that in the present application, in order to ensure normal movement of the prism support body 20, it is necessary to ensure that the first contact and stop surface 125 and the first stop surface 23 and the second contact and stop surface 126 and the second stop surface 24 cannot be contacted simultaneously.

In particular, the first contact stop surface 125 and the second contact stop surface 126 are each arranged obliquely with respect to the first plate section 121.
