The prism carrier is arranged on the prism bracket, and the prism carrier includes a second magnet module and corresponds to the second coil assembly, so that the prism carrier rotates around the second axis, and the second axis is perpendicular to the first axis. The prism is arranged on the prism carrier. The limiting structure is arranged between the prism bracket and the prism carrier to limit the movement of the prism carrier on the plane formed by the second axis and the third axis, and the third axis is perpendicular to the first axis and the second axis.

[0005] In one embodiment, the limiting structure includes a first accommodating groove, a first rolling body, a second accommodating groove and a second rolling body. The first accommodating groove and the first rolling body are correspondingly arranged on one side of the prism bracket and the prism carrier on the second axis, and the first rolling body rolls in the first accommodating groove. The second accommodating groove and the second rolling body are correspondingly arranged on the other side of the prism bracket and the prism carrier on the second axis, and the second rolling body rolls in the second accommodating groove.

[0049] Please read first Figures 1 to 5 , Figure 1 is a three-dimensional diagram of the prism motor module of the first embodiment, Figure 2 is a three-dimensional exploded view of the prism motor module of the first embodiment, Figure 3 This is a three-dimensional exploded view of the fixing base and the prism bracket of the first embodiment. Figure 4 is a three-dimensional exploded view of the prism bracket and the prism carrier of the first embodiment, Figure 5This is a schematic diagram of the prism bracket assembly of the first embodiment being arranged on the prism carrier but separated from the fixing seat. The prism motor module of this embodiment can be applied to mobile phone camera devices, augmented reality devices, vehicle-mounted camera devices, and other periscope image capture devices that have image autofocus and optical image stabilization functions. For the convenience of subsequent description, the direction extending along the height direction of the prism motor module is set as the first axis X, the direction extending along the long side direction of the prism motor module is set as the second axis Y, and the direction extending along the short side direction of the prism motor module is set as the third axis Z. The first axis X, the second axis Y, and the third axis Z are perpendicular to each other. Furthermore, by Figure 1 and Figure 2 It can be seen that in order to prevent the internal components of the prism motor module from being disturbed by external elements during operation and to improve the overall aesthetics, a shell 90 can be set on the outermost side of the prism motor module to cover the entire prism motor module.

[0050] Depend on Figure 2 It can be seen that the prism motor module of this embodiment includes a fixing seat 10, a prism bracket 20, a prism carrier 30, a prism 40 and a limiting structure 50. The fixing seat 10 includes a body 11, a driving module 12, two balls 13 and a limiting groove 14. The body 11 has a bottom surface 111 and a side surface 112 perpendicular to the bottom surface 111. The driving module 12 includes a first coil component 121 and a second coil component 122, the first coil component 121 is arranged on the bottom surface 111, and the second coil component 122 is arranged on the side surface 112. The first coil component 121 and the second coil component 122 can both be two groups of coils respectively arranged on the bottom surface 111 and the side surface 112 in a left-right symmetrical manner, or there can be fewer or more groups of coils, which can be configured according to needs.

[0051] The two balls 13 are respectively disposed on two opposite sides of the bottom surface 111 of the body 11. Figure 2 The ball bearing 13 on the left side is shielded and not shown, but in fact there is also an identical ball bearing 13 at the symmetrical upper left corner. The limiting groove 14 is disposed on the bottom surface 111 of the body 11 .

[0052] See also Figure 2 and Figure 3 The prism bracket 20 is assembled on the fixing seat 10, and the prism bracket 20 includes a first magnet module 21 and a guide shaft 22. The assembly position of the first magnet module 21 will correspond to the position of the first coil assembly 121 arranged on the bottom surface 111, and the number of the first magnet modules 21 will also be set corresponding to the number of the first coil assemblies 121. In this embodiment, since the first coil assembly 121 has two groups of coils arranged obliquely on the left and right, the first magnet module 21 also corresponds to two groups of magnets arranged obliquely on the left and right, and each group of magnets is composed of positive and negative bipolars.

[0053] The guide shaft 22 is fixedly disposed on the bottom side of the prism bracket 20 and will correspond to the stop groove 14, so that the prism bracket 20 can rotate around the first axis X with the guide shaft 22 as the axis after being assembled on the fixing seat 10. The center of the guide shaft 22 is set at the extension of the center of the corresponding prism 40, and cooperates with the stop groove 14 on the fixing seat 10. That is to say, the position where the stop groove 14 is set on the bottom surface 111 will correspond to the setting position of the guide shaft 22. In addition to guiding the guide shaft 22 to rotate in the stop groove 14, it can also limit the movement range of the guide shaft 22 when it may move during the rotation process. In this embodiment, the guide shaft 22 can be a metal column or a ceramic column, so as to be embedded in the prism bracket 20, and the end surface of the guide shaft 22 that presses against the stop groove 14 is a circular arc surface.

[0054] At the same time, the two balls 13 disposed on the fixing base 10 also contact the bottom side of the prism bracket 20, and provide two more points of support for the prism bracket 20 in addition to the guide shaft 22. In this way, the fixing base 10 and the prism bracket 20 are contacted by point contact instead of surface contact, thereby reducing the dynamic and static friction when the fixing base 10 and the prism bracket 20 move relative to each other, so as to improve the jitter problem that may be caused by the dynamic and static friction of the motor in the OIS optical anti-shake function structure when switching at a small angle.

[0055] Next, continue reading Figure 2 and Figure 5 The prism carrier 30 is assembled on the prism bracket 20 , and the prism carrier 30 includes a second magnet module 31 and corresponds to the second coil assembly 122 , so that the prism carrier 30 rotates around the second axis Y. The second magnet module 31 is disposed on the back side of the prism carrier 30 . The prism 40 is disposed on the prism carrier 30 . Figure 5 It is shown that when the prism carrier 30 is assembled to the prism bracket 20, the second magnet module 31 will still be exposed on the back side. When the prism carrier 30 is assembled to the prism bracket 20 and then assembled to the fixing base 10, the second magnet module 31 will correspond to the second coil assembly 122. In this embodiment, the second coil assembly 122 is composed of two groups of coils arranged on the side 112 in a bilaterally symmetrical manner, but the second magnet module 31 is extended by a group of long strip magnets to correspond to the entire second coil assembly 122 at the same time. In other embodiments, the second magnet module 31 can also be arranged and arranged corresponding to the number of the second coil assemblies 122 in the same manner as the first magnet module 21.

[0056] Depend on Figure 2 and Figure 4 It can be seen that the limiting structure 50 is disposed between the prism bracket 20 and the prism carrier 30 to limit the movement of the prism carrier 30 on the plane formed by the second axis Y and the third axis Z, that is, to limit the movement of the prism carrier 30 on the horizontal plane.

[0057] Thus, the rotation of the prism 40 on the first axis X in the prism motor module of the present embodiment is based on the first coil assembly 121, the first magnet module 21 and the guide shaft 22 arranged between the fixing seat 10 and the prism bracket 20. The rotation of the prism 40 on the second axis Y is based on the second coil assembly 122, the second magnet module 31 and the limiting structure 50 arranged between the prism bracket 20 and the prism carrier 30. Further, the contact between the fixing seat 10 and the prism bracket 20 is made through the contact between the ball 13 and the guide shaft 22. In addition, the prism bracket 20 and the prism carrier 30 can also be arranged in a point contact or line contact manner through the limiting structure 50. In this way, the dynamic and static friction forces of the fixing seat 10, the prism bracket 20 and the prism carrier 30 during relative movement are reduced by point contact or line contact instead of surface contact, so as to improve the jitter problem that may be generated by the motor in the OIS optical anti-shake function structure when switching at a small angle due to the dynamic and static friction forces.

[0058] Next, please also refer to Figure 2 and Figure 4 The limiting structure 50 includes a first accommodating groove 51, a first rolling body 52, a second accommodating groove 53 and a second rolling body 54. The first accommodating groove 51 and the first rolling body 52 are correspondingly arranged on one side of the prism bracket 20 and the prism carrier 30 on the second axis Y, and the first rolling body 52 rolls in the first accommodating groove 51. The second accommodating groove 53 and the second rolling body 54 are correspondingly arranged on the other side of the prism bracket 20 and the prism carrier 30 on the second axis Y, and the second rolling body 54 rolls in the second accommodating groove 53.

[0059] The first accommodating groove 51 and the second accommodating groove 53 can be respectively disposed in one of the prism support 20 and the prism carrier 30, and the first rolling body 52 and the second rolling body 54 are respectively disposed in the other of the prism support 20 and the prism carrier 30. Figure 4 It can be seen that the first receiving groove 51 and the second receiving groove 53 are respectively disposed on the opposite left and right sides of the prism bracket 20. The first rolling body 52 and the second rolling body 54 are disposed on the opposite left and right sides of the prism carrier 30. In addition, the arrangement is not limited to the receiving grooves being disposed on the prism bracket 20 or the prism carrier 30. Alternatively, the first receiving groove 51 may be disposed on the prism bracket 20, the second receiving groove 53 may be disposed on the prism carrier 30, and the rolling body may be disposed on the other one.

[0060] Further, by Figure 4It can be seen that in this embodiment, the first rolling body 52 is a metal ball or a ceramic ball and is fixed to the prism carrier 30, and the first receiving groove 51 is a triangular groove and is provided in the prism bracket 20. In application, the shape of the first receiving groove 51 is not limited to a triangular groove, and can also be a quadrangular groove, a semicircular groove, etc., as long as it can limit the movement of the first rolling body 52 in the direction of the first axis X and the third axis Z. When the prism carrier 30 rotates around the second axis Y relative to the prism bracket 20, if a displacement on the plane is generated, the range of movement on the plane formed by the first axis X and the third axis Z (i.e., the horizontal plane) can also be controlled under the mutual limitation of the first receiving groove 51 and the first rolling body 52.

[0061] In addition, in the present embodiment, the second rolling body 54 is a metal roller or a ceramic roller, and the axial direction of the second rolling body 54 is parallel to the second axis Y, and the second receiving groove 53 is a V-shaped groove or an arc groove. The shape of the second receiving groove 53 is only for example, and it can also be used to allow the second rolling body 54 of a metal roller or a ceramic roller to roll smoothly therein, and its shape is not limited. The second rolling body 54 is in the form of a metal roller or a ceramic roller, and when the prism carrier 30 rotates around the second axis Y relative to the prism bracket 20, it can provide a mutual movement in the form of line contact between the prism bracket 20 and the prism carrier 30, thereby reducing friction. In addition, by using balls or rollers made of metal or ceramic materials, the friction can be further reduced while increasing the structural strength.

[0062] In addition, this embodiment is illustrated by the first rolling body 52 being a metal ball or a ceramic ball, the first receiving groove 51 being a triangular groove, the second rolling body 54 being a metal roller or a ceramic roller, and the second receiving groove 53 being a V-shaped groove or a circular arc groove. However, in other embodiments, the rolling bodies may all be balls, and the receiving grooves may all be triangular grooves, quadrangular grooves, or semicircular grooves. Alternatively, the rolling bodies may all be rollers, and the receiving grooves may all be V-shaped grooves or circular arc grooves. In this way, the effect of reducing friction and increasing structural strength may also be achieved.

[0063] Next, see Figure 3 The fixing base 10 further includes a magnetic member 15 disposed on the bottom surface 111 and below the first coil assembly 121. The magnetic member 15 and the first magnet module 21 disposed at the bottom of the prism bracket 20 attract each other to press the guide shaft 22 and the ball 13 to ensure that the shaft is not decoupled or the fixing base 10 and the prism bracket 20 are not separated or misaligned during the operation.

[0064] Also, see Figure 4The prism carrier 30 further includes a magnet 32, and the prism bracket 20 further includes another magnetic member 23, and the magnet 32 ​​and the other magnetic member 23 are arranged at corresponding positions. The magnetic member 23 on the prism bracket 20 can be directly embedded in the prism bracket 20 by insert molding. The magnet 32 ​​arranged on the prism carrier 30 and the magnetic member 23 of the prism bracket 20 will attract each other to press the first rolling body 52 and the second rolling body 54 toward the first receiving groove 51 and the second receiving groove 53, so as to ensure that the prism carrier 30 and the prism bracket 20 are not decoupled or the prism carrier 30 and the prism bracket 20 are away from each other or misaligned during the relative movement.

[0065] Next, please refer to Figure 6 , Figure 6 1 is a perspective exploded view of the fixing seat and the prism bracket of the second embodiment. The same structure and connection relationship in the second embodiment as in the first embodiment are not further described. The main difference between this embodiment and the first embodiment is the number of balls arranged on the fixing seat 10. In this embodiment, at least two of the plurality of balls 13a are arranged on one side of the bottom surface 111 of the body 11, and at least another two of the balls 13a are arranged on the other side of the bottom surface 111 of the body 11. Figure 6 Only two balls 13a on the right side can be seen, and the two balls 13a are set in a circular groove to limit the rolling range of the two balls 13a. At the same time, there can also be a corresponding circular groove at the bottom of the prism bracket 20, so that the rolling range of the two balls 13a can be better limited after the two are combined. In addition, in this embodiment, Figure 6 Although not shown, the corresponding position on the left side of the fixing seat 10 also has two balls 13 a and a circular groove which are the same as those on the right side.

[0066] In this way, in addition to providing a larger ball 13 as in the first embodiment, at least two balls 13a may be provided as in the second embodiment to reduce the friction between the fixing base 10 and the prism bracket 20 during relative movement through point contact, thereby making the movement smoother and improving the jitter problem that may be caused by the motor in the OIS optical image stabilization function structure when switching at small angles due to dynamic and static friction.

[0067] Although the present invention is disclosed as above with the aforementioned embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the patent protection scope of the present invention shall be determined by the scope of the claims attached to this specification.

[0068] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims of the present invention.
