The lenses can be roughly divided into wide-angle lenses with short focal length and telephoto lenses with long focal length. However, placing a long focal length lens in an optical module increases the thickness of the electronic device, making it difficult to meet the requirements of mobile terminal devices for thin and light thinness. In the prior art, a periscope type design is usually used, that is, the optical path is laid flat and a turning mirror is added to turn the optical path by 90 degrees, so that the entire optical system is laid flat to reduce the overall height.

[0040] In the present application, the orientation words such as "upper, lower, top, bottom" used without the opposite description are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of the components themselves, but the above orientation words are not used to limit the present application.

[0041] In order to solve the poor performance problem of the prism motor in the prior art, the present application provides a prism driving motor, a camera device and an electronic equipment.

[0042] And the electronic equipment in the present application can be a mobile terminal such as a mobile phone, a tablet computer, a notebook computer and the like with the camera device in the present application. At the same time, the camera device in the present application has the prism driving motor described below.

[0043] It should be noted that the prism driving motor in the present application is mainly applied to a periscopic lens, so the prism driving motor in the present application can be used in cooperation with a lens motor in the periscopic lens. That is, the prism driving motor in the present application mainly drives the prism in the periscopic lens to move to realize the anti-shake adjustment of the periscopic lens.

[0044] As shown in FIGS. 1-10, the prism driving motor in the present application includes a base assembly 10 having a containing space, and further includes a rotating frame assembly 20, a first rotating shaft assembly 30, a prism support 40, a second rotating shaft assembly 50, a first driving assembly 60 and a second driving assembly 70 arranged in the containing space. The two ends of the first rotating shaft assembly 30 are connected with the rotating frame assembly 20 and the base assembly 10 respectively, so that the rotating frame assembly 20 can rotate around the first rotating shaft assembly 30 relative to the base assembly 10; the prism support 40 is movably connected with the rotating frame assembly 20, and the rotating frame assembly 20 can drive the prism support 40 to move together, and the prism support 40 has an inclined surface for placing a prism 100; the second rotating shaft assembly 50 passes through the prism support 40, and the two ends of the second rotating shaft assembly 50 are connected with the rotating frame assembly 20 respectively, so that at least a part of the prism support 40 can rotate around the second rotating shaft assembly 50 relative to the rotating frame assembly 20; at least a part of the first driving assembly 60 is arranged on the base assembly 10, and at least another part of the first driving assembly 60 is arranged on the rotating frame assembly 20 correspondingly; at least a part of the second driving assembly 70 is arranged on the base assembly 10, and at least another part of the second driving assembly 70 is arranged on the prism support 40 correspondingly.

[0045] When the prism driving motor in the present application is used, since the prism driving motor has the first driving assembly 60 and the second driving assembly 70, when the prism driving motor needs to be adjusted for anti-shake, the first driving assembly 60 can be used to drive the rotating frame assembly 20 and the prism support 40 to move together around the first rotating shaft assembly 30, and the second driving assembly 70 can be used to drive the prism support 40 to move around the second rotating shaft assembly 50 relative to the rotating frame assembly 20 and the base assembly 10. Since the first rotating shaft assembly 30 and the second rotating shaft assembly 50 are used to replace the ball-type anti-shake driving in the existing prism driving motor in the present application, the prism driving motor in the present application has a larger supporting surface compared with the existing ball-type prism driving motor, and is easier to control. Therefore, the prism driving motor in the present application effectively solves the problem of poor performance of the prism motor in the prior art.

[0046] It should be noted that the rotation of the rotating frame assembly 20 and the prism support 40 in the present application is a small-angle rotation, and only needs to achieve anti-shake adjustment. Therefore, the rotating frame assembly 20 and the prism support 40 in the present application do not need to rotate a full circle.

[0047] Specifically, the axis of the first rotating shaft assembly 30 is parallel to the Y-axis, and the axis of the second rotating shaft assembly 50 is parallel to the X-axis.

[0048] Specifically, the first rotating shaft assembly 30 includes a first connecting shaft 31, both ends of the first connecting shaft 31 are connected with the rotating frame assembly 20 and the base assembly 10 respectively. In addition, the first rotating shaft assembly 30 further includes at least two first shaft sleeves 32, and the rotating frame assembly 20 and the base assembly 10 are respectively provided with at least one first shaft sleeve 32 corresponding to both ends of the first connecting shaft 31.

[0049] In one specific embodiment of the present application, for the way that the first shaft sleeve 32 is installed on the rotating frame assembly 20 and the base assembly 10, a dispensing groove can be arranged on the circumferential inner wall of the hole corresponding to the first shaft sleeve 32 on the rotating frame assembly 20 and the base assembly 10, so that the first shaft sleeve 32 is fixed by dispensing after being installed in the corresponding hole, thereby ensuring that the rotating frame assembly 20 can drive the first shaft sleeve 32 thereon to rotate relative to the base assembly 10 and the first connecting shaft 31. Preferably, the first connecting shaft 31 can be made of ceramic or metal material, so as to ensure the structural strength of the rotating frame assembly 20 and more smooth rotation.

[0050] Therefore, when the rotating frame assembly 20 moves around the first rotating shaft assembly 30 in the present application, the rotating frame assembly 20 can drive the first shaft sleeve 32 thereon to rotate around the first connecting shaft 31.

[0051] Optionally, the prism driving motor further comprises at least one ball 80, and the base assembly 10 and / or the bottom surface of the rotating frame assembly 20 is provided with at least one mounting groove 81 corresponding to the ball 80, and at least part of the ball 80 is movably arranged in the mounting groove 81. For the movement form of the ball 80, the ball 80 can rotate or roll in the mounting groove 81, and the specific size and shape of the mounting groove 81 can be adjusted according to the different requirements of the movement of the ball 80.

[0052] And as known from the above, the mounting groove 81 can be arranged only on the base assembly 10, only on the rotating frame assembly 20, or on both the base assembly 10 and the rotating frame assembly 20.

[0053] Optionally, the ball 80 is a plurality of balls 80, and the plurality of balls 80 are arranged at intervals around the circumference of the first connecting shaft 31.

[0054] In one specific embodiment of the present application, the number of balls 80 is three, the three balls 80 are arranged at intervals, and the base assembly 10 and the rotating frame assembly 20 are respectively provided with three groups of mounting grooves 81 arranged opposite to each other, and each ball 80 corresponds to a different group of mounting grooves 81. In this embodiment, the ball 80 rotates in the mounting groove 81 of the base assembly 10, that is, the mounting groove 81 of the base assembly 10 limits the ball, and the ball 80 and the mounting groove 81 of the rotating frame assembly 20 are in relative motion, or the ball 80 rolls in the mounting groove 81 of the rotating frame assembly 20, but in fact the mounting groove 81 of the rotating frame assembly 20 moves with the rotating frame assembly 20. In this way, not only can the mounting groove 81 of the rotating frame assembly 20 provide a rolling plane for the ball 80, but also the internal space of the prism driving motor can be saved, the internal structure of the prism driving motor is more compact, and the miniaturization design of the prism driving motor is facilitated.

And it should be noted that at this time the plurality of balls 80 have a height higher than the mounting boss 11 in the Y-axis direction. At the same time, in the present application, the ball 80 and the first connecting shaft 31 can also support the rotating frame assembly 20, thereby reducing the contact between the rotating frame assembly 20 and the base assembly 10, or making the rotating frame assembly 20 suspended on the base assembly 10 in the Y-axis direction.

[0056] Optionally, the base assembly 10 and the rotating frame assembly 20 are provided with steel plates corresponding to the positions in contact with the balls 80, so as to ensure the structural strength and reliability of the base assembly 10 and the rotating frame assembly 20 when the prism driving motor is impacted by external force.

[0057] Specifically, the second shaft assembly 50 comprises a second shaft sleeve 51 and a second connecting shaft 52. The second shaft sleeve 51 is two, and one of the second shaft sleeves 51 is arranged on each of the opposite side walls of the rotating frame assembly 20 in the X-axis direction. The two ends of the second connecting shaft 52 extend out of the prism support 40 and into different second shaft sleeves 51.

[0058] Optionally, the second shaft sleeve 51 in the present application can be a split structure or an integral structure. When the second shaft sleeve 51 is a split structure, the second shaft sleeve 51 comprises a welding portion 511 and a sleeve portion 512. The welding portion 511 is welded with the rotating frame assembly 20. The sleeve portion 512 is connected with the rotating frame assembly 20, and the welding portion 511 and the sleeve portion 512 have at least one set of clamping jaws 513 and clamping holes 514 matched with each other.

[0059] In one embodiment of the present application, the second shaft sleeve 51 is a split structure, and when the second shaft sleeve 51 is installed on the rotating frame assembly 20, the welding portion 511 and the sleeve portion 512 can be assembled through the matched clamping jaws 513 and clamping holes 514, and then the second shaft sleeve 51 is fixed on the rotating frame assembly 20 through the direction of glue dispensing, and finally reinforced by welding. Preferably, the welding portion 511 is made of stainless steel, so as to ensure that the welding portion 511 has high welding strength, and the periphery of the welding portion 511 has a plurality of clamping jaws 513. The sleeve portion 512 is made of copper, and the periphery of the sleeve portion 512 has a plurality of clamping holes 514. Of course, a glue groove is arranged at the position of the rotating frame corresponding to the second shaft sleeve 51 to prevent glue overflow.

[0060] Specifically, in the Y-axis direction, the rotating frame assembly 20 has a limiting protrusion 21 extending towards the prism support 40, the prism support 40 has an avoiding groove 41 corresponding to the limiting protrusion 21, and the two ends of the second connecting shaft 52 pass through the side wall of the avoiding groove 41 and extend into the second shaft sleeve 51.

By such arrangement, the fit between the prism support 40 and the second connecting shaft 52 can be ensured to be more stable, so that the prism support 40 can rotate more stably around the second connecting shaft 52.

[0061] And in one embodiment of the present application, the cross section of the limiting protrusion 21 on the YZ plane is a right trapezoid, and the two sides of the right trapezoid correspond to the limiting surface of the limiting protrusion 21 respectively, and when the prism support rotates clockwise and counterclockwise around the X axis, it can be limited by the abutting of the different limiting surfaces and the inner wall surface of the avoidance groove 41, so the avoidance groove 41 also has a vertical inner wall and an inclined inner wall, and the inclined inner wall is arranged on the side of the avoidance groove 41 away from the stand component.

[0062] In the present application, the stand component 10 includes a bottom plate 12 parallel to the XZ plane, a vertical plate 13 parallel to the XY plane, and two side plates 14 parallel to the YZ plane, the first drive assembly 60 includes at least two first drive coils 61 and at least two first drive magnets 62, at least one first drive coil 61 is arranged on each side plate 14, and the first drive magnet 62 corresponding to the first drive coil 61 is arranged on the rotating frame assembly 20; the second drive assembly 70 includes at least one second drive coil 71 arranged on the vertical plate 13 and at least one second drive magnet 72 corresponding to the second drive coil 71 arranged on the prism support 40. Therefore, in this embodiment, the mounting boss 11 and the ball 80 are arranged on the bottom plate 12. The opening of the abutting recess 411 faces the bottom plate 12 of the stand component 10. The limiting protrusion 21 of the rotating frame assembly 20 is arranged between the two connecting plates 22.

[0063] Preferably, the prism driving motor further comprises at least one first magnetic sheet 90, at least one adsorbing magnet 94, and at least one second magnetic sheet 91, one of the first magnetic sheet 90 and the adsorbing magnet 94 is arranged on the bottom plate 12, and the other is arranged on the rotating frame assembly 20 correspondingly; the second magnetic sheet 91 is arranged on the vertical plate 13 corresponding to the second driving magnet 72, and the rotating frame assembly 20 is embedded with a steel sheet at least corresponding to part of the second driving magnet 72.

In a specific embodiment of the present application, the first magnetic sheet 90 and the adsorbing magnet 94 are both two, and the two first magnetic sheets 90 are arranged on the bottom plate, and the two adsorbing magnets 94 are arranged on the rotating frame assembly correspondingly.

When the prism driving motor is impacted by external force, the limiting boss 221 and the damping glue can protect the internal structure of the prism driving motor.
