Description of invention: TECHNICAL FIELD The present invention relates to a lens shifting mechanism, which is applied to an autofocus or zoom lens group, and more particularly to a radial inclined bevel on a bottom edge or an outer edge of a lens sleeve. And correspondingly abutting on a corresponding inclined surface of a corresponding radial movable body, so that when the radial movable body is driven to move radially inward/outward due to the braking force of the brake, the inclined surface corresponding to each other can be used The push between them relatively causes the lens to produce a forward/backward axial movement on the central axis. [Prior Art] On the handheld electronic devices currently used, such as digital cameras, mobile phones with shooting functions, and notebook-type electronic devices, there is a miniature lens module with auto-focusing (AF) or zooming. A compact camera module (CCM), the lens module basically comprises: a cavity formed by the upper cover and the bottom cover; a lens consisting of a lens group and a lens sleeve (iensh〇lder) The sleeve is disposed in the cavity and can be slidably displaced back and forth in the direction of the central axis; and a lens displacement/driving mechanism whose main purpose is to provide an braking force by using an actuator (actuating force) ) to drive the lens to produce an axial shifting action on the central axis in the cavity to achieve autofocus or zoom. 3 200937093 The actuator used in conventional lens shifting mechanisms contains a number of different modes, such as a piezoelectric motor, which is formed using piezoelectric materials such as US 7,212,358, US 2003/ 0227560, US2006/0044455A1, JP2006-293083, JP2006-101611, etc., using a voltage applied to a piezoelectric motor to generate an actuating force; another type called a voice coil motor (VCM), It is formed by a coil, a magnet and an elastic member such as a spring or a spring. For example, US 7,262,927, US 7,196,978, US 7,002,879, US 6,961,090, US 6,687,062, US20070133110 > JP2005037865 ' JP2005258355 ' ® W02007026830 Etc., most of these conventional techniques use a coil and a permanent magnet to be used in combination, such as fixing a coil on the periphery of the lens to form a synchronous linkage, and then arranging one or several rings in the outer circumference of the coil. A permanent magnet is held stationary, so that when the coil is energized, it can generate upward or downward electromagnetic force in the magnetic field established by the permanent magnet. The lens is driven to move; in addition, there is a lens shifting mechanism using a shape memory alloy (SMA), which utilizes the heat-shrinking property of the SMA to serve as a driving force source for the actuator, WUS6. , 307, 678B2, US6, 449, 434B1, US2007058070, ❹ US2007047938, JP2005275270, JP2005195998, etc. However, the SMA heat shrinking cold movement is slower, and it can not be driven by the interlocking structure between the brake (actuat〇r) and the lens. Easy to achieve instant autofocus or zoom. However, in the conventional lens shifting mechanism, the brake used includes a plurality of different modes to choose from, but the brake is generally integrated with other components of the lens module such as the most important lens. The design 'that is, when determining the mode of the brake used, the interlocking structure between the brake and the lens (including the lens group and a lens sleeve) is also set at the same time as disclosed in US 2006/0044455 A1, whereby the brake device 4 200937093 ❹ Ο The generated braking force (actuatingforce) can directly drive the lens to generate an axial displacement action on the central axis of the cavity. Therefore, the brakes of different modes cannot communicate the braking force by the same linkage structure. Can not be replaced; in particular, the brake of the conventional lens shifting mechanism, the direction of the braking force is mostly in the same direction as the optical axis (ie, the central axis of the lens), so that the amount of movement is 1:1 'more braking power, In order to increase the relative movement of the lens, other interlocking structures must be added, which complicates the overall structure and is not conducive to mass production. Reducing the cost; in addition, in the prior art, there is a driving method that uses a bevel to drive the lens shift, such as US 5,930,544, which uses a first movable member (firstmovement member to drive the lens to the left and right shifts) and at the same time By using a second movement member and a lever fulcrum to drive the upper and lower displacement of the lens, the central axis of the lens exhibits an elliptical trajectory displacement effect, resulting in a complicated structure, and The referenced beveling effect is not used to drive the lens for axial movement, that is, it does not use the radial motion of a brake to convert the axial movement of the lens via the bevel action; therefore, the development has a high resolution and increases the relative movement of the lens. The new technology to solve the problem that the amount of movement in the lens shifting mechanism is 1.1 and the interlocking structure between the brake and the lens must be set at the same time will be urgently needed. SUMMARY OF THE INVENTION The main objective of the present invention is to provide a lens shifting mechanism, a lens module for supplying or zooming, which mainly comprises: at least a bottom edge or at a position where the lens sleeve is radially inclined to: the axis f Outer edge: Outer::夂ίί—A radial moving body is placed on the lens sleeve corresponding to the outside? Each of the 'reversely inclined second inclined faces to respectively reduce the bottom edge of the j-head sleeve or the first inclined surface on the outer edge; and the fine brake generates a braking force to drive the radial moving bodies to synchronize 5 200937093 When the inner/outward radial movement, the first inclined surface on the bottom edge or the outer edge of the lens sleeve can be driven by the radial movable body by the pushing action between the first and second inclined surfaces corresponding to each other. The low/high position of one of the second slopes is shifted to a high/low position, and the lens is relatively moved forward/backward on the central axis (optical axis) to achieve autofocus or zoom The function. Another object of the present invention is to provide a lens shifting mechanism, wherein the brake used in the braking portion can further select a voice coil motor (VCM), a piezoelectric motor (piezoelectric motor), and shape memory according to the design requirements of the lens module. A brake formed by an alloy (SMA) or a group of brakes formed by a coil and an electromagnet (a 0) is controlled by an actuating force to drive a lens in a lens module. An axial displacement action is generated on the central axis (optical axis) in the cavity. Another object of the present invention is to provide a lens shifting mechanism, which can further configure a spring on the lens (or the lens sleeve), when the brake force (actuating force) or the driving force of the radial movable body disappears or does not function. The spring provides a relative restoring force to the lens to achieve dynamic balance or return to the original position for autofocus or zoom. The lens shifting mechanism of the present invention is mainly configured by a second inclined surface that can be moved radially and an axially movable first inclined surface, wherein the first inclined surface that is axially movable is attached to the lens cover. The bottom edge or the outer edge of the cylinder is upper, and the radially movable second slope is disposed on a radially movable radial movable body, and corresponds to the first slope on the bottom edge or the outer edge of the lens sleeve Abutting on a second inclined surface of the radially movable body; wherein, when the radially movable body is driven to move radially inward or outward, the push between the first and second inclined surfaces corresponding to each other is abutted The abutting action can drive the lens to move axially forward or backward relative to the central axis. For example, when the radial moving body moves toward the central axis (ie, moves inward), the inclined surface can force the bottom of the lens sleeve. 6 200937093 The first slope on the edge or the outer edge is up and down, and the upper slope is shifted forward; and if the moving body is pq + in the middle, the second slope is moved (ie, moved outward) , so that the lens is relatively down in the center = down direction. Again, this hair The shifting lens of the lens achieves the two bevels of the lens shift and the elliptical surface that can be moved axially. The first choice of the radial movement is to provide the lens with a different axial angle in the cavity. Shift action or precision shift action. #(光轴)上出 [Embodiment] 下列 The following is a clear and detailed description. The preferred embodiment is illustrated and the following figures are omitted.

The movable body 31 respectively corresponds to two first inclined surfaces 23 on the bottom edge or the outer edge of the lens sleeve 22; and each of the radial movable bodies 31 is provided with a second inclined surface which is inclined obliquely and has the same inclination as the first inclined surface 23. 32, the first inclined surface 23 corresponding to the bottom edge or the outer edge of the lens sleeve 22 respectively is dead, wherein the length of the second inclined surface 32 of the radial movable body 31 is greater than the first edge of the lens sleeve 22 The length of the ramp 23 is such that the length ramp 23 is slidably displaceable over the length of the second ramp 32. The braking portion 30 includes a brake for control by a camera controller (not shown) The brake in the brake portion 3 is configured to generate a braking force for driving the radially movable body 31 to move radially inward or outward. By the above structure 'When the braking portion 30 utilizes its brake, a radial braking force (shown by an arrow A in FIG. 4) is generated inward (toward the central axis Z) to drive the radially inwardly moving bodies 31 to move radially inwardly. At this time, the first inclined surface 23 of the lens sleeve 22 can be driven by the second inclined surface 32 of the radial movable body 31 by the pushing action between the first and second inclined surfaces 23 and 32 which are mutually abutted. 200937093 Upper-lower position: Upper climb and shift to second slope 32 Upper high position 襄H = Upper sleeve 22 (ie lens 20) is relatively moving in the center of the heart (none (five)) 4 arrow B1i braking part = system "no effect or generated radial braking force (as shown in Figure 4 arrow disease: not ^ Xiao lost or reversed (outward) radial system; force, this: = 2 followed by the first - and second oblique (four) 32 between the push 柢 Λ 7 < — = the first slope 23 of the Tao 22 lost the forward support force 'and 1) 仫 two '芨 = 31 苐 two slopes 32 The upper-high position (as shown in Fig. 5) is shifted downward to the second slope 32-lower than the 'point position (such as the C lens sleeve. (ie, the lens 20) is relatively at the central axis ( Light?) The rear axial movement returns to the original position. Referring again to Fig. 6, the relative displacement relationship between the axial displacement amount (h) and the second displacement amount (d) of the lens 20 of the present invention is illustrated.矣 Corresponding to the slope of the first and second slopes 23, 32 corresponding to f is Θ. When the second, the shirt θ 'where" is the pumping movement efficiency, U 1,77 can be based on the first and second slopes 23, The frictional force of 32 is different. For different financial qualities, the face is small and the mode can be obtained by actual experiments. Assume that when f1 '=45, tan Θ=1 'so h 〇=d; and when Θ ^, Then h^d, such as a ==53. When Ρ 1,33 (1, such as a = 63.43. When h = 2d, so as long as the two pairs of the first pair, the slope of the first slope, U, 32 The slope 1 is designed as ^45 15, which can be used to increase the relative movement of the lens, so as to solve the problem that the braking force of the brake of the conventional lens shifting mechanism is mostly with the optical axis = i and the movement amount is 1:1. It is more expensive to use the Mirror 20 design that moves along the glaze to the fascinating fascination. It is hoped that the lens can be smashed. 245. For example, the slanting movable body 31 of the first and second slanting faces 23 and 32 can be faded. to One.=60., h=1.73d. At this time, the radial amount only (d) only moves the imm, the axial shift 9 200937093, the quantity (h) moves 1.73mm, and the same, for different lens 2q design When it is desired to relatively precisely move the lens 20 in the axial direction, the slopes of the first and second slopes 23, 32 can be inclined by one. $45. For example, one = 30., h = 0.577d, at this time, the diameter When the radial displacement amount (d) of the movable body 31 is moved by 1 mm, the axial displacement amount (h) is shifted by 577 mm. However, in order to make the lens 20 move smoothly and smoothly, the inclined slope Θ should not be less than 22.3 when proper lubrication is applied and no other machine is applied. Should not be greater than 71 5 . . Referring again to FIGS. 1, 7, and 8, the number and position of the lens shifting machine of the present invention are not limited to two or more, etc., but the cost and assembly of the lens shifting mechanism 3 must be considered; The square mechanism 3 is equal to the 'angle ring ff bottom edge (as shown in Figure 1-7) or the outer edge (as shown in Figure 8-10 = sinking peripheral, preferably the square lens module J shown in Figure 1 and two Iff two lens shifting mechanisms 3 are located at the center of the lens module 1 at the position of the diagonal position 3, that is, at the diagonal position, or four lens shifts are provided at the four corner positions of the interior; In the case of the framing 2, two lens shifting positions can be set; the short-side inner end position symmetrical with the central axis of the figure ❹ the short-side inner end position imaginary mechanism 3 is symmetric with the central axis inside the lens module 1 = : 3⁄4 the cylinder mechanism 3 is equally angularly generated, and the braking force is applied to the axial body 31 provided by the brake of the moving portion 3', thereby stably moving axially on the lens sleeve 22. Mirror 20 is made in the center axis 光 (optical axis), = the brake mode of the brake is used, and it is not allowed to move, and the inactive body 31 is synchronized. Or the outward radial-bevel 23 affects the pushing between the two mutually corresponding abutting 200937093 32; therefore, the voice coil motor (VCM) and the piezoelectric motor can be selected according to the design requirements of the lens module. A piezoelectric motor, a brake formed using a shape memory alloy (SMA), or a brake in a group of brakes formed by a coil and an electromagnet, relatively increases the selectivity of the brake used in the braking portion 30. As shown in FIG. 1 and 7, the braking portion 30 further includes a guiding device 33. As shown in FIG. 1, the radial movable body 31 can be stably slid radially by the rail device 33. The lens of the present invention The shifting mechanism 3 can further be provided with a spring 40 on the lens 20 or its lens cymbal sleeve 22, when the braking force of the brake of the braking portion 30 or the driving force of the radial movable body 31 disappears or does not act. The spring 40 can provide a relative restoring force to the lens 20 to achieve dynamic balance or return to the original position of the lens 20 to achieve an autofocus or zoom effect. As for the elastic type of the spring 40, such as pressure Compression Springs or extension springs, structural types such as coil springs or non-coil springs, number or set position are not limited and may vary depending on the design of the lens module or the direction of motion of the lens. The above description is only the preferred embodiment of the present invention, and the present invention is only for the purpose of illustration and not limitation; those skilled in the art understand that the scope of the invention Many changes, modifications, and even equivalents are made, but all fall within the scope of the present invention.
