Referring to fig. 2, fig. 3 and fig. 4, in an embodiment, the elastic element 130 further includes a fixing portion 132, the fixing portion 132 is connected to the connecting portion 131, the first board 110 and the second board 120 are both provided with a groove 150, and the fixing portion 132 is clamped in the groove 150, so that the elastic element 130 is fixedly connected to the first board 110 and the second board 120. The fixing portion 132 is configured to fixedly connect the elastic member 130 to the first plate 110 and the second plate 120, so that the elastic member 130 is not easily separated from the first plate 110 and the second plate 120 during the use of the anti-shake apparatus 1000. It can be understood that the shape and size of the groove 150 on the first plate 110 and the second plate 120 should match the shape and size of the fixing portion 132 of the elastic member 130, so that the fixing portion 132 of the elastic member 130 is not easily separated from the groove 150, and the connection stability between the elastic member 130 and the first plate 110 and the second plate 120 is strong.
In one embodiment, the connecting portion 131 and the fixing portion 132 are connected end to form a closed structure, and the elastic member 130 is disposed in a central symmetrical manner about a central axis of the accommodating space 121. When the elastic member 130 is of a closed structure, the elastic member 130 can provide a corresponding elastic force in a plane perpendicular to the central axis of the accommodating space 121, in both the transverse direction and the longitudinal direction, so that when the second plate 120 is displaced relative to the first plate 110, the initial homing can be achieved under the influence of the elastic force. Moreover, since the elastic members 130 are distributed in a central symmetry manner about the central axis of the accommodating space 121, the elastic force provided by the elastic members 130 is the same in each direction in a plane perpendicular to the central axis of the accommodating space 121, so that the stress of the member to be prevented from being shaken is more balanced.
It is understood that the connecting portion 131 and the fixing portion 132 of the elastic member 130 may be of an integral structure or a split structure. When the connecting portion 131 and the fixing portion 132 of the elastic member 130 are of an integrated structure, the elastic member 130 has higher stability, and the connecting portion 131 and the fixing portion 132 are not easily separated during use; when the connection portion 131 and the fixing portion 132 of the elastic member 130 are of a split structure, if one of the portions is damaged, the connection portion can be replaced in time, so that the normal function of the elastic member 130 is not affected, and the fault tolerance of the elastic member 130 is improved.
In one embodiment, there are a plurality of elastic members 130, and the plurality of elastic members 130 are sequentially sleeved along a direction perpendicular to the central axis of the accommodating space 121. When the plurality of elastic members 130 are provided, the plurality of elastic members 130 are sequentially sleeved along the direction perpendicular to the central axis of the accommodating space 121, so that a more uniform elastic acting force can be provided in the plane perpendicular to the central axis of the accommodating space 121, and the preliminary homing of the anti-shake members to be treated is facilitated. Moreover, since there are a plurality of elastic members 130, even if one of the elastic members 130 is damaged to cause an elastic function failure, the other elastic members 130 can still have corresponding elastic functions, thereby improving the fault tolerance of the anti-shake apparatus 1000. In one embodiment, the plurality of elastic members 130 are three-way concentric spring plates.
It should be noted that, in process design and production, due to the limitation of error or process level, the verticality in the embodiment of the present application may not be strictly perpendicular to each other, that is, in the anti-shake apparatus 1000 provided in the embodiment of the present application, the included angle between the direction in which the plurality of elastic members 130 are sequentially sleeved and the central axis of the accommodating space 121 is close to 90 °, but not 90 °, but the error of the included angle between the two directions in the anti-shake apparatus 1000 provided in the embodiment of the present application caused by the process should be acceptable to those skilled in the art, and the included angle should not affect the implementation of the object of the embodiment of the present invention.
In one embodiment, the elastic member 130 has a dimension of 10 μm or more in an extending direction along the central axis of the accommodating space 121. When the elastic member 130 connects the first plate body 110 and the second plate body 120, the elastic member 130 is easily damaged due to a shearing stress in an extending direction along the central axis of the accommodating space 121, and thus, in order to prevent the structure of the elastic member 130 from being damaged due to the shearing stress, the structure of the elastic member 130 should have a certain shearing resistance in the extending direction along the central axis of the accommodating space 121. It can be understood that, when the anti-shake apparatus 1000 provided by the embodiment of the present invention is used for anti-shake processing of a lens, since the size of the lens is small, correspondingly, the size of the first plate 110 and the second plate 120 is not too large, when the size of the elastic member 130 in the extending direction along the central axis of the accommodating space 121 is greater than or equal to 10 μm, in this direction, the elastic member 130 can have sufficient structural strength to avoid the structure thereof from being damaged by the shearing stress from the first plate 110 and the second plate 120.
Referring to fig. 1 and 5, in an embodiment, the first sensing element 140 is disposed opposite to the second sensing element 210, and when the first sensing element 140 is offset and staggered from the second sensing element 210, the second sensing element 210 controls the first sensing element 140 to move to a position opposite to the second sensing element 210. The relative arrangement of the first sensing part 140 and the second sensing part 210 enables the first sensing part 140 and the second sensing part 210 to sense the relative position and control the homing more effectively.
In one embodiment, the first sensing element 140 is a magnetic body, the second sensing element 210 includes a sensing chip 211, a coil 212 and a driver (not shown), the sensing chip 211 and the coil 212 are both disposed on the control board 200, the coil 212 is sleeved on the periphery of the sensing chip 211, one end of the driver is electrically connected to the sensing chip 211, and the other end of the driver is electrically connected to the coil 212. When the to-be-anti-shake element drives the second plate 120 to shift due to shake, the sensing chip 211 senses the magnetic force change of the first sensing element 140 due to shift, so as to change the current and output the current to the driver, the driver converts the difference stroke compensation value according to the input current, and outputs the current with corresponding magnitude to the coil 212, the coil 212 conducts the current output by the driving element, and generates a magnetic field with corresponding magnetic field strength, the magnetic field generated by the coil 212 generates a magnetic acting force on the first sensing element 140, and the first sensing element 140 is influenced by the magnetic acting force and drives the to-be-anti-shake element on the second plate 120 to realize homing.
It is understood that the structural configurations of the first sensing element 140 and the second sensing element 210 include, but are not limited to, the above one, and may also be various structural configurations as long as they satisfy the corresponding functions, and they are not specifically limited herein.
Referring to fig. 1 and fig. 2, in an embodiment, the number of the first sensing elements 140 is multiple, the multiple first sensing elements 140 are distributed on the second plate 120 at intervals, the number of the second sensing elements 210 is multiple, and each second sensing element 210 is disposed opposite to one first sensing element 140. When first response piece 140 and the quantity of second response piece 210 relative to it have a plurality ofly, can realize more accurate positioning to make and treat that anti-shake can realize accurate playback, thereby avoid leading to treating that anti-shake can't reach corresponding job requirement because of positional deviation. It can be understood that, since the number of the first sensing elements 140 and the second sensing elements 210 is multiple, even if one of the first sensing elements 140 or the second sensing elements 210 fails due to structural damage, the other first sensing elements 140 and second sensing elements 210 can still meet the corresponding functional requirements, thereby improving the fault tolerance of the anti-shake apparatus 1000.
In one embodiment, the plurality of first sensing members 140 are symmetrical with respect to at least two symmetry axes at the same time, and the plane of the at least two symmetry axes is perpendicular to the central axis of the accommodating space 121. Under the above structure, since the plurality of first sensing members 140 are symmetrical about at least two symmetry axes at the same time, and the plurality of second sensing members 210 disposed opposite to the plurality of first sensing members 140 are symmetrical about at least two symmetry axes at the same time, when the second sensing members 210 control the first sensing members 140 to move along the extending direction of at least two symmetry axes, the stress of the first sensing members 140 is more uniform, so that the movement thereof is more stable. In a specific embodiment, the at least two axes of symmetry are a horizontal axis and a vertical axis, and the plurality of first sensing elements 140 and the plurality of second sensing elements 210 are both symmetrically distributed about the horizontal axis and the vertical axis, so that the acting force of the second sensing elements 210 on the first sensing elements 140 is more uniform in a two-dimensional plane containing the horizontal axis and the vertical axis, so that the first sensing elements 140 can move back to the position opposite to the second sensing elements 210 more smoothly.
It should be noted that, in process design and production, due to limitation of errors or process levels, the verticals in the embodiment of the present invention may not be strictly perpendicular to each other, that is, in the anti-shake apparatus 1000 provided in the embodiment of the present invention, an included angle between a plane where at least two symmetry axes are located and a central axis of the accommodating space 121 is close to 90 °, but not 90 °, but an error of an included angle between the two directions in the anti-shake apparatus 1000 provided in the embodiment of the present invention caused by the process should be acceptable to those skilled in the art, and the included angle should not affect implementation of the object of the embodiment of the present invention.
