Description

Technical Field

[0001] The present application relates to the technical field of photography, and particularly to a camera structure therefor. Background Art

[0002] A camera device usually has an anti-shake mechanism. When a user holds a shooting device to take an image, the user's hand-held shooting device may have unstable shaking or vibration, which affects the captured image. The optical anti-shake technology can compensate for the light of the image to obtain a captured image with good quality. However, the conventional technology adopts a ball-type anti-shake design. The ball rolls in a V-shaped groove, and there are multiple dot contacts between the ball and the V-shaped groove. In addition to the small contact area of the dot contacts, the stress of the dot contacts is also relatively easy to concentrate on the center point. Thus, the stress of the dot contacts of the ball will cause a greater impact on the accommodating groove or the surface of the structure. In the long run, the position of the dot contacts will lead to serious friction, and abnormal problems such as dirt pollution caused by debris. Summary of the Utility Model

For the sake of clarity, many implementation details will be described together in the following narrative. However, it should be understood that these implementation details should not be used to limit the present application. That is to say, in some embodiments of the present application, these implementation details are not necessary.

In the following embodiments, the same reference numerals will be used to represent the same or similar components.

[0043] Please refer to Figures 1 to 5 , Figure 1 which is a perspective view of the first embodiment of the imaging structure of the present application, Figure 2 is Figure 1 a sectional view taken along line A-A' of Figure 3 is Figure 2 an enlarged view of region D of Figure 4 is Figure 1 a sectional view taken along line B-B' of Figure 5 and is Figure 1 a sectional view taken along line C-C' of . As shown in the figure, the present application provides an imaging structure 1, which includes a moving structure 11 and an imaging lens 12. The moving structure 11 includes a first moving part 111, a second moving part 112 and a moving member 113, and the moving member 113 is disposed between the first moving part 111 and the second moving part 112. The moving member 113 includes opposite end portions 1131 and a circumferential surface 1132 located between the end portions 1131. The long axis C of the moving member 113 passes through the end portions 1131, and the circumferential surface 1132 surrounds the long axis C, and the circumferential surface 1132 is an arc surface. In some embodiments, in the direction along the long axis C, the circumferential surface 1132 gradually moves away from the long axis C from the end portions 1131 to the middle position between the end portions. In some embodiments, in the direction along the long axis C, the curvature of the circumferential surface 1132 is less than the curvature of a circle., The first moving part 111 has a first surface 1111, the second moving part 112 has a second surface 1121, and the circumferential surface 1132 of the moving member 113 abuts against the first surface 1111 and the second surface 1121 respectively. The first moving part 111 and the second moving part 112 are displaced relative to each other, and the moving member 113 moves on the first surface 1111 and the second surface 1121. The imaging lens 12 is displaced by the moving structure 11. The moving structure 11 of the present embodiment can provide the imaging lens 12 with functions of automatic focusing (i.e., AF) or / and optical image stabilization (i.e., OIS). In some embodiments, the moving member 113 as a whole can be approximated as an ellipsoid or an olive sphere, etc., which belongs to a non-spherical or non-cylindrical shape, but its circumferential surface 1132 is in the shape of a curved surface or an arc surface. In some embodiments, in some embodiments, when the first moving part 111 and the second moving part 112 are displaced relative to each other, the moving member 113 rolls on the first surface 1111 and the second surface 1121. In some embodiments, the end portions 1131 are respectively circular planes.

[0044] Please refer to together Figure 3 It should be noted that there are some punctuation and grammar issues in the original Chinese text that may affect the understanding. The above translation is based on the original text as accurately as possible., in this embodiment, the first surface 1111 of the first moving part 111 and the second surface 1121 of the second moving part 112 are polygonal concave surfaces according to the side profile of the peripheral surface 1132 of the moving part 113, and the polygonal concave surface has a plurality of contact points with respect to the moving part 113. In some embodiments, a part of the polygonal concave surface of the first surface 1111 is parallel to the long axis C of the moving part 113, and a part of the polygonal concave surface of the second surface 1121 is parallel to the long axis C of the moving part 113. In some embodiments, the first surface 1111 and the second surface 1121 are also symmetric with respect to the long axis C of the moving part 113. The first surface 1111 and the second surface 1121 of this embodiment are respectively composed of a bottom surface 10P and inclined surfaces 11P on both sides of the bottom surface 10P, where the included angle between the bottom surface 10P and the inclined surface 11P is an obtuse angle, and the bottom surface 10P is parallel to the long axis C of the moving part 113. The bottom surface 10P and the two inclined surfaces 11P of the first surface 1111 or the second surface 1121 are polygonal concave surfaces formed according to the side profile of the moving part 113, so that the peripheral surface 1132 of the moving part 113 has corresponding contact points with respect to the bottom surface 10P and / or the two inclined surfaces 11P of the first surface 1111 or the second surface 1121 respectively. In this embodiment, the peripheral surface 1132 of the moving part 113 has corresponding contact points with respect to the bottom surface 10P and the two inclined surfaces 11P of the first surface 1111 and the second surface 1121 respectively, that is, there are six contact points between the peripheral surface 1132 and the first surface 1111 and the second surface 1121. In some embodiments, when both sides of the moving part 113 are abutted against the first surface 1111 and the second surface 1121, the contact points where the moving part 113 abuts against the first surface 1111 or the second surface 1121 will change in shape due to stress. That is to say, in terms of the cross-section of Figure 3 , originally the contact points where the first surface 1111 and the second surface 1121 are abutted by the peripheral surface 1132 are point contacts, but after the contact points are deformed, they will fit the contour of the peripheral surface 1132 to a certain extent, changing the original point contact state to a line contact. In this embodiment, from the cross-section view, the contact points where the first surface 1111 and the second surface 1121 are abutted by the peripheral surface 1132 are line contacts, and in the actual three-dimensional state, they are surface contacts. The abutting surfaces where the bottom surface 10P and the two inclined surfaces 11P of the first surface 1111 are abutted and deformed by the moving part 113 are respectively arc surfaces, that is, the stress-bearing area of the first surface 1111 is the sum of the areas of these arc surfaces. The abutting surfaces where the bottom surface 10P and the two inclined surfaces 11P of the second surface 1121 are abutted and deformed by the moving part 113 are respectively arc surfaces, that is, the stress-bearing area of the second surface 1121 is the sum of the areas of these arc surfaces.

[0045] In the present embodiment, taking the moving member 113 and the spherical ball installed between the first surface 1111 and the second surface 1121 as an example for comparison, where the diameter of the ball is taken as the short-axis length of the moving member 113, the following description is given. The curvature of the peripheral surface 1132 of the moving member 113 in the present embodiment is smaller than the surface curvature of the spherical ball. Therefore, the contact surface between the peripheral surface 1132 of the moving member 113 and the first surface 1111 and the second surface 1121 is larger than the pressing surface between the circular surface of the ball and the first surface 1111 and the second surface 1121. The center points of the contact surface between the peripheral surface 1132 of the moving member 113 and the first surface 1111 and the second surface 1121 are not concentrated, but are arranged according to the positions of the bottom surface 10P and the two inclined surfaces 11P. Therefore, the stress of the moving member 113 is not easily concentrated at the same point, and the stress of the moving member 113 can be dispersed on the peripheral surface 1132, so that the moving member 113 can be prevented from having a large stress friction effect on the first surface 1111 or the second surface 1121. On the contrary, the center point position of the circular surface used for the ball to abut is clear, the stress of the ball is relatively easy to be concentrated at the same point, and the friction force of the ball on the surface is large.

[0046] Furthermore, the deeper the moving member 113 presses against the first surface 1111 and the second surface 1121, the larger the pressure-bearing area of the first surface 1111 and the second surface 1121. When the moving member 113 presses against the ball with a greater depth, the increase in the pressure-bearing area of the first surface 1111 and the second surface 1121 pressed by the moving member 113 is greater than the increase in the pressure-bearing area of the first surface 1111 and the second surface 1121 pressed by the ball. The amount of shape change of the first surface 1111 and the second surface 1121 relative to the moving member 113 does not need to be large, and the first surface 1111 can provide sufficient supporting force to fix the moving member 113. In this way, the moving member 113 is not likely to slip relative to the first surface 1111 and the second surface 1121, so that the service life of the moving structure 11 can be extended. In some embodiments, the elements undergoing compressive deformation can be opposite. For example, the element undergoing compressive deformation can be the peripheral surface 1132 of the moving member 113 instead of the first surface 1111 and the second surface 1121. In this case, the hardness of the peripheral surface 1132 of the moving member 113 is less than that of the first surface 1111 and the second surface 1121. When the peripheral surface 1132 abuts against the first surface 1111 and the second surface 1121, the peripheral surface 1132 is locally deformed by the acting force of the first surface 1111 and the second surface 1121. At this time, the abutting surfaces of the peripheral surface 1132 of the moving member 113 abutted by the bottom surface 10P and the inclined surface 11P of the first surface 1111 and the second surface 1121 are respectively flat. In some embodiments, the elements undergoing compressive deformation can occur simultaneously on the peripheral surface 1132, the first surface 1111 and the second surface 1121.

[0047] Please refer to Figure 6 , which is an exploded perspective view of the imaging structure of the present application. As shown in the figure, in the present embodiment, the imaging structure 1 further includes a base assembly 13 and a first moving assembly 14. The first moving assembly 14 is located inside the base assembly 13. The moving structure 11 includes a first moving structure 11A. There is a first moving structure 11A between the inner wall of the base assembly 13 and the outer wall corresponding to the first moving assembly 14. The base assembly 13 has a first moving part 111A, the first moving assembly 14 has a second moving part 112A, and there is a moving member 113A between the first moving part 111A and the second moving part 112A. The moving members 113 in the present embodiment are multiple, and the multiple moving members 113 are located on both sides of the imaging structure 1. The multiple moving members 113 are arranged between the base assembly 13 and the first moving assembly 14 along the first direction Z. The first moving structure 11A guides the reciprocating movement of the first moving assembly 14 relative to the base assembly 13 in the first direction Z (i.e., the vertical direction).

[0048] Furthermore, the base assembly 13 includes a base 131 and a first coil 132. The first coil 132 is disposed on the base 131. The first moving assembly 14 includes a first moving body 141 and a first magnet 142. The first magnet 142 is disposed on the first moving body 141. The first coil 132 corresponds to the first magnet 142, and the magnetic pole direction of the first magnet 142 is parallel to the first direction Z. The base 131 has a base receiving groove 1310, and the groove side wall of the base receiving groove 1310 has a first notch 1311. The first coil 132 is located within the first notch 1311. The first moving body 141 has a first receiving groove 1411, and the first magnet 142 is disposed within the first receiving groove 1411. The position of the first notch 1311 corresponds to the position of the first receiving groove 1411.

[0049] As described above, the magnetic pole directions of the first magnets 142 are arranged parallel to the first direction Z, that is, the S pole and the N pole of the magnetic poles are arranged in a vertical direction. When an electric current passes through the first coil 132 to generate a corresponding magnetic field, the magnetic field of the first coil 132 interacts with the magnetic poles of the first magnets 142, and then a thrust or a suction force is generated on the first moving assembly 14 relative to the base 131. In this way, the first moving assembly 14 moves relative to the base 131 against the plurality of moving members 113A. Further, the first moving assembly 14 is driven to reciprocate relative to the base 131 in the first direction Z. In this way, the camera lens 12 is displaced by the first moving structure 11A, that is, the automatic focusing function of the imaging structure 1.

[0050] Please refer to Figures 7 to 9 , Figure 7 is Figure 6 the enlarged view of area E of Figure 8 the partial exploded perspective view of the imaging structure and Figure 9 is another partial exploded perspective view of the imaging structure. As shown in the figure, it further includes a second moving assembly 15. The moving structure 11 includes a second moving structure 11B. The first moving assembly 14 has a receiving groove 140. The second moving assembly 15 is disposed within the receiving groove 140 of the first moving assembly 14. There is a second moving structure 11B between the receiving groove 140 of the first moving assembly 14 and the bottom of the second moving assembly 15 corresponding thereto. The first moving assembly 14 has a first moving portion 111B, and the second moving assembly 15 has a second moving portion 112B. The second moving structure 11B guides the second moving assembly 15 to reciprocate relative to the first moving assembly 14 in the second direction Y (i.e., the horizontal direction), and the second direction Y is perpendicular to the first direction Z.

[0051] As described above, there are three moving members 113B in this embodiment. The bottom of the accommodating groove 140 of the first moving assembly 14 has three first moving portions 111B. The second moving assembly 15 is an L-shaped structure. The second moving portions 112B are disposed at both ends and the L-corner position of the second moving assembly 15. The three moving members 113B form a movable supporting horizontal plane, and the three moving members 113B are correspondingly assembled between the second moving portions 112B of the second moving assembly 15 and the first moving portions 111B of the first moving assembly 14.

[0052] In this embodiment, the imaging structure 1 further includes a lens base assembly 16. The moving structure 11 includes a third moving structure 11C. The lens base assembly 16 is disposed on the second moving assembly 15. There is a third moving structure 11C between the top of the second moving assembly 15 and the bottom of the lens base assembly 16 corresponding thereto. The second moving assembly 15 has a first moving portion 111C, and the lens base assembly 16 has a second moving portion 112C. The third moving structure 11C guides the lens base assembly 16 to reciprocate relative to the second moving assembly 15 in the third direction X (i.e., the horizontal direction). The third direction X is perpendicular to the second direction Y. Also, the third direction X is perpendicular to the first direction Z.

[0053] As described above, there are three moving members 113C in this embodiment. The second moving assembly 15 is an L-shaped structure. The positions of the three moving members 113C correspond to the positions of the three moving members 113B. The three moving members 113C are also disposed at the two end points and the L-corner position of the second moving assembly 15. The three moving members 113C form a movable supporting horizontal plane. The lens base assembly 16 is a lens frame for assembling the imaging lens 12. The second moving portions 112C are disposed at the three corner positions of the bottom of the lens base assembly 16. The three moving members 113C are correspondingly assembled between the second moving assembly 15 and the lens base assembly 16.

[0054] In this embodiment, the second moving structure 11B and the third moving structure 11C are used to provide displacement in the horizontal direction. One end of the plurality of moving members 113B of the second moving structure 11B with the second surface 1121 faces inward. One end of the plurality of moving members 113C of the third moving structure 11C with the second surface 1121 also faces inward. In addition, the imaging lens 12 of this embodiment is disposed on the lens base assembly 16. The lens base assembly 16 has an assembling hole 160, and the imaging lens 12 can be fitted into the assembling hole 160. Thus, the imaging lens 12 is driven to displace through the base assembly 13, the first moving assembly 14, the second moving assembly 15, and the lens base assembly 16.

[0055] In this embodiment, the base assembly 13 includes a base 131 and a second coil 133. The second coil 133 is disposed on the base 131. The groove sidewall of the base accommodation groove 1310 of the base 131 further has a second notch 1312. The first notch 1311 and the second notch 1312 are located on different groove sidewalls of the base accommodation groove 1310. The second coil 133 is located within the second notch 1312. The lens base assembly 16 includes a lens base 161 and a second magnet 162. The second magnet 162 is disposed on the lens base 161. The lens base 161 has a second accommodation groove 1611. The second magnet 162 is disposed within the second accommodation groove 1611. The position of the second notch 1312 corresponds to the position of the second accommodation groove 1611. Thus, the second magnet 162 corresponds to the second coil 133, and the magnetic pole directions of the second magnet 162 are arranged in a manner parallel to the second direction Y, that is, the S pole and the N pole of the magnetic poles are arranged in a horizontal direction. When current passes through the second coil 133, the magnetic poles of the second coil 133 and the magnetic poles of the second magnet 162 interact with each other, and then the first moving assembly 14 generates a thrust or a suction force relative to the base 131. Thus, the lens base assembly 16 undergoes a displacement in the second direction Y through the second moving structure 11B between the second moving assembly 15 and the first moving assembly 14. Further, it drives the lens base assembly 16 and the second moving assembly 15 to generate a reciprocating displacement relative to the first moving assembly 14 in the second direction Y.

[0056] Furthermore, the base assembly 13 includes a base 131 and a third coil 134. The third coil 134 is disposed on the base 131. The groove sidewall of the base accommodation groove 1310 of the base 131 further has a third notch 1313. The first notch 1311, the second notch 1312, and the third notch 1313 are respectively located on different groove sidewalls of the base accommodation groove 1310. The third coil 134 is located within the third notch 1313. The lens base assembly 16 includes a lens base 161 and a third magnet 163. The third magnet 163 is disposed on the lens base 161. The lens base 161 has a third accommodation groove 1612. The third magnet 163 is disposed within the third accommodation groove 1612. The position of the third notch 1313 corresponds to the position of the third accommodation groove 1612. Thus, the third coil 134 corresponds to the third magnet 163, and the magnetic pole directions of the third magnet 163 are parallel to the third direction X. When current passes through the third coil 134, the magnetic poles of the third coil 134 and the magnetic poles of the third magnet 163 interact with each other, and then the first moving assembly 14 generates a thrust or a suction force relative to the base 131. Thus, the lens base assembly 16 undergoes a displacement in the third direction X through the third moving structure 11C. Further, it drives the lens base assembly 16 to generate a reciprocating displacement relative to the second moving assembly 15 in the third direction X. Thus, the imaging lens 12 undergoes a displacement through the second moving structure 11B and the third moving structure 11C, that is, the optical image stabilization function of the imaging structure 1.

[0057] In this embodiment, the moving structure 11 includes a first moving structure 11A, a second moving structure 11B, and a third moving structure 11C. The first moving structure 11A, the second moving structure 11B, and the third moving structure 11C have the same structure (as Figure 3 shown). The first moving structure 11A is used for reciprocating displacement in the first direction Z, the second moving structure 11B is used for reciprocating displacement in the second direction Y, and the third moving structure 11C is used for reciprocating displacement in the third direction X. The purpose of the above-mentioned moving structure 11 is to provide the camera lens 12 with moving adjustment in three axial directions.

[0058] Please refer back to Figure 6 , the imaging structure 1 further includes a circuit board 17. The circuit board 17 is disposed on the side of the base assembly 13. The circuit board 17 is located on the side of the first coil 132, the second coil 133, and the third coil 134, and the circuit board 17 is electrically connected to the first coil 132, the second coil 133, and the third coil 134 respectively. Furthermore, the imaging structure 1 further includes a spring piece 18. The spring piece 18 is disposed on the first moving component 14, and the spring piece 18 presses against the upper part of the lens holder assembly 16. The spring piece 18 is disposed along the three sides of the first moving component 14, and the side of the spring piece 18 extends downward to a fixing portion 181. The first moving component 14 has corresponding fixing grooves 143, and the fixing portion 181 of the spring piece 18 is correspondingly fixed in the fixing grooves 143 of the first moving component 14. The spring piece 18 can be used to limit the lens holder assembly 16 corresponding to the three sides of the first moving component 14. The spring piece 18 can be used to limit the moving range of the lens holder assembly 16 and the camera lens 12 in the first direction Z (i.e., the moving range of focusing), and to ensure that the lens holder assembly 16 is assembled in the first moving component 14.

[0059] In addition, as Figure 10 shown, the imaging structure 1 further includes a protective cover 19. The protective cover 19 has an orifice 191. The protective cover 19 covers the base assembly 13, enclosing the first moving component 14, the second moving component 15, the lens holder assembly 16, the circuit board 17, and the spring piece 18 within the base assembly 13, and the camera lens 12 of the lens holder assembly 16 passes through the orifice 191 of the protective cover 19.

[0060] Please refer to Figure 11, is a schematic diagram of the second embodiment of the moving structure of the present application; as shown in the figure. The difference between this embodiment and the first embodiment lies in the shapes of the first surface 1111 and the second surface 1121. The shapes of the first surface 1111 and the second surface 1121 of this embodiment are symmetrical about the long axis C of the moving member 113. Hereinafter, the first surface 1111 will be described. The first surface 1111 of this embodiment is composed of a bottom surface 20P, two first inclined surfaces 21P, and two second inclined surfaces 22P. The inclination angles of the first inclined surface 21P and the second inclined surface 22P relative to the bottom surface are different. On both sides of the bottom surface 20P, two first inclined surfaces 21P and two second inclined surfaces 22P are sequentially connected. The above is a polygonal concave surface formed according to the side profile of the moving member 113. In this way, the moving member 113 has corresponding contact points with the bottom surface 20P, two first inclined surfaces 21P, and two second inclined surfaces 22P of the first surface 1111 or the second surface 1121 respectively. The polygonal concave surface of this embodiment has more contact points with the moving member 113, which can stabilize the sliding stability of the moving member 113.

[0061] Please refer to Figure 12 , is a schematic diagram of the third embodiment of the moving structure of the present application; as shown in the figure. The difference between this embodiment and the first embodiment lies in the shapes of the first surface 1111 and the second surface 1121. The first surface 1111 and the second surface 1121 of this embodiment are in a planar shape. The moving member 113 has a contact point with the first surface 1111 and the second surface 1121 respectively. This embodiment has less restriction on the moving member 113, and the moving member 113 has a large degree of freedom to roll. The first surface 1111 and the second surface 1121 of this embodiment are parallel to the long axis C.

[0062] Please refer to Figure 13 , is a schematic diagram of the fourth embodiment of the moving structure of the present application; as shown in the figure. The difference between this embodiment and the third embodiment lies in the shapes of the first surface 1111 and the second surface 1121. The first surface 1111 and the second surface 1121 of this embodiment are in an arc shape. The moving member 113 has a contact point with the first surface 1111 and the second surface 1121 respectively. The arc shapes of the first surface 1111 and the second surface 1121 are closer to the arc of the side profile of the peripheral surface 1132 of the moving member 113. Therefore, the contact area of the first surface 1111 and the second surface 1121 with respect to the moving member 113 is larger than that of the planar shape in the third embodiment. In addition, the arc shapes of the first surface 1111 and the second surface 1121 can also keep the moving member 113 rolling at the low point of the arc surface during the rolling process. In some embodiments, the arc curvature of the first surface 1111 and the second surface 1121 is smaller than the arc curvature of the peripheral surface 1132 of the moving member 113.

[0063] Please refer to Figure 14 , which is a schematic diagram of the fifth embodiment of the moving structure of the present application; as shown in the figure. The difference between this embodiment and the fourth embodiment lies in the arc surface angles of the first surface 1111 and the second surface 1121. The first surface 1111 and the second surface 1121 of this embodiment are in an arc surface shape, wherein the first surface 1111 and the second surface 1121 are deflected at the same angle with respect to the long axis C of the moving member 113. In other words, the first surface 1111 has an included angle with respect to the wall surface of the outer side wall of the base 131, and the second surface 1121 has an included angle with respect to the wall surface of the inner side wall of the first moving assembly 14. In this way, the moving member 113 will also exhibit a sliding at an oblique angle. The deflection angle of this embodiment is not limited and can be adjusted according to the needs of the user.

[0064] Please refer to Figure 15 , which is a schematic diagram of the sixth embodiment of the moving structure of the present application. As shown in the figure, the difference between this embodiment and the first embodiment lies in the structural difference between the first surface 1111 and the second surface 1121. In this embodiment, the peripheral surface 1132 of the moving member 113 has corresponding contact points with respect to the two inclined surfaces 31P of the first surface 1111 and the second surface 1121, that is, there are four contact points between the peripheral surface 1132 and the first surface 1111 and the second surface 1121. The bottom surface 30P of the first surface 1111 and the second surface 1121 has a gap with respect to the peripheral surface 1132 of the moving member 113, that is, the peripheral surface 1132 of the moving member 113 is suspended between the bottom surfaces 30P of the first surface 1111 and the second surface 1121. Furthermore, in this embodiment, the polygonal concave surface of the first surface 1111 and the second surface 1121 has a plurality of contact points with respect to the moving member 113, and the number of surfaces of the polygonal concave surface can be greater than or equal to the number of contact points of the moving member 113, that is, the moving member 113 does not completely contact all the surfaces of the polygonal concave surface, and this can be adjusted according to the needs of the user. In this way, this embodiment can reduce the contact points of the moving member 113 with the first surface 1111 and the second surface 1121, thereby reducing the rolling resistance of the moving member 113.

[0065] Please refer to Figure 16, which is a schematic diagram of the seventh embodiment of the moving structure of the present application. As shown in the figure, the difference between this embodiment and the sixth embodiment lies in the difference in the surface structure shape of one of the first surface 1111 and the second surface 1121. In this embodiment, the first surface 1111 is in a planar shape, and the moving member 113 has one contact point with respect to the first surface 1111. The surface structures of the first surface 1111 and the second surface 1121 of this embodiment are surface structures that are asymmetric with respect to the major axis C. In other words, the number of contact points of the moving member 113 with respect to the first surface 1111 and the second surface 1121 is also inconsistent. The restriction of the first surface 1111 on the moving member 113 in this embodiment is less, that is, the degree of freedom for the moving member 113 to roll is large, and the restriction of the second surface 1121 on the moving member is more, that is, the degree of freedom for the moving member 113 to roll is smaller. The above can be adjusted according to the needs of the user. The first surface 1111 of this embodiment is parallel to the major axis C. In different embodiments, the second surface 1121 is in a planar shape, and the second surface 1121 is parallel to the major axis C, while the first surface 1111 is like Figure 3 , Figure 11 , Figure 13 or Figure 15 the structural shape.

[0066] In summary, the present application provides an imaging structure. Through the design that the moving member is an ellipsoid, the moving member abuts against the first surface as the first elliptical surface, and the moving member abuts against the second surface as the second elliptical surface. In this way, the contact stress of the elliptical surface can be more dispersed and not concentrated, thereby reducing the frictional damage of the moving member to the first surface and the second surface.
