Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As shown in fig. 1 to 3, in one embodiment, an anti-shake module 10 is provided, which includes a housing 100, a first connecting portion 210, a mounting body 300, a second connecting portion 310, an elastic reset piece 400, and a power supply unit 600. Thus, when in use, the power supply unit 600 supplies power to the elastic reset piece 400; the elastic reset piece 400 generates heat after being electrified, so that contraction is generated, the movable mounting body 300 rotates relative to the shell 100 under the action of the contraction force, and accordingly corresponding displacement deviation can be compensated.
As shown in fig. 1 to 3, in particular, the case 100 is provided with a mounting cavity 110 having a receiving space; the first connecting portion 210 is fixedly disposed in the mounting cavity 110; the mounting body 300 is rotatably disposed in the mounting cavity 110 and disposed below the first connection portion 210; the second connecting portion 310 is fixedly disposed on the mounting body 300; the elastic reset piece 400 is used for electrically connecting the first connecting portion 210 and the second connecting portion 310, and the elastic reset piece 400 can be heated to shrink and drive the mounting body 300 to rotate; the power supply unit 600 is electrically connected to the elastic reset device 400. So, when installation body 300 takes place corresponding displacement deviation, power supply unit 600 resets piece 400 power supply to elasticity for elasticity resets piece 400 and is heated the shrink, because first connecting portion 210 is fixed and set up in the top of installation body 300 relatively installation body 300, can stimulate installation body 300 and rotate to predetermineeing the position relatively casing 100 when elasticity resets piece 400 shrink, and then can compensate displacement deviation. In addition, when the power supply unit 600 stops supplying power to the elastic restoring member 400, the elastic restoring member 400 is extended and restored by its own restoring force, so that the mounting body 300 is restored with respect to the housing 100. The preset position is a position at which the displacement of the mounting body 300 can compensate for the displacement deviation caused by the impact of the external force when the mounting body 300 moves to the preset position. The mounting body 300 is disposed below the first connection portion 210, and means that the mounting body 300 is located below the first connection portion 210 along an axial direction of the mounting body 300.
Meanwhile, compared with the form of driving by using a motor in the prior art, the mounting body 300 is only required to be arranged below the first connecting part 210, the first connecting part 210 and the second connecting part 310 are connected by using the elastic resetting piece 400, and the mounting body 300 can be driven to move by using the thermal contraction of the elastic resetting piece 400 to supplement displacement deviation.
In addition, along the axial direction of the installation body 300, the first connection portion 210 can be fixedly arranged above the second connection portion 310 (i.e. the projection of the first connection portion 210 on the installation body 300 does not coincide with the projection of the second connection portion 310 on the installation body 300, and along the axial direction of the installation body 300, the first connection portion 210 is located above the second connection portion 310), so that the central axis of the elastic reset piece 400, the projection line of the elastic reset piece 400 on the installation body 300, and the plumb line from the first connection portion 210 to the installation body 300 are arranged in a right triangle, and the central axis of the elastic reset piece 400 is the hypotenuse of the right triangle, the elastic reset piece 400 is heated and contracted to pull the installation body 300 to rotate, so that the elastic reset piece 400 has a larger contraction allowance, and the installation body 300 has a larger rotation angle. So set up, can make elasticity reset piece 400 can realize bigger turned angle through the flexible volume of littleer to prevent that elasticity from resetting piece 400 and leading to the impaired and strain fatigue of structure to lead to the bad effect that life descends because of excessive flexible, turned angle here means the angle that installation body 300 rotated around corresponding axis of rotation.
Wherein, the housing 100 is used for supporting, the housing 100 can be an injection molding or other structures meeting the use requirement.
The first connecting portion 210 and the second connecting portion 310 can be connected to the elastic reset piece 400 by setting the outlines of the first connecting portion 210 and the second connecting portion 310 to hook shapes, and only the two ends of the elastic reset piece 400 need to be connected to hooks respectively.
The mounting body 300 is used for providing a mounting position of the lens assembly, and the mounting body 300 can drive the lens assembly to generate corresponding displacement when moving, so that the lens assembly can be subjected to corresponding displacement compensation; the mounting body 300 may be a mounting plate, a mounting block, or other structure that can meet the mounting requirements of the lens assembly.
The elastic restoring member 400 may be a SAM (shape memory alloy) wire or other element that can contract when heated and contract when cooled and can be restored when cooled and extended when not heated.
The power supply unit 600 may be any one of the existing components capable of supplying and cutting off power to the elastic reset piece 400; the electrical connections may be made by wires or other conductive elements.
Of course, the position of the mounting body 300 may also be detected by the position detecting assembly 500, and when the position detecting assembly 500 detects that the mounting body 300 has a corresponding displacement deviation with respect to the housing 100 (for example, the mounting body 300 shakes under the impact of an external force to have a corresponding displacement), the power supply unit 600 may supply power to the elastic reset piece 400. The position detecting unit 500 may be any conventional unit capable of detecting the position of the mounting body 300 in real time. As shown in fig. 2 to 4, for example, the hall magnetic steel 510 may be fixed to the mounting body 300 by adhering or clamping by matching the hall magnetic steel 510 with the hall sensor 520, the hall sensor 520 may be fixed to the housing 100 by adhering or inserting, the hall magnetic steel 510 and the hall sensor 520 are arranged at an interval, and when the mounting body 300 moves correspondingly, the hall sensor 520 sends a corresponding pulse signal, thereby detecting the position of the mounting body 300.
As shown in fig. 2 to 4, the anti-shake module 10 further includes a first conductive body 200 and a second conductive body 320 (wherein, the second conductive body 320 may be partially or completely embedded in the mounting body 300, so as to save the occupied space and meet the development requirement of miniaturization). One end of the first conductive body 200 is provided with a first connection portion 210, and the other end of the first conductive body 200 is electrically connected to the power supply unit 600. One end of the second conductive body 320 is provided with a second connecting portion 310, and the other end of the second conductive body 320 is electrically connected to the power supply unit 600. Therefore, the power supply unit 600, the first conductive body 200, the elastic reset piece 400 and the second conductive body 320 form a power supply loop, so that the elastic reset piece 400 can be normally powered on and powered off. The first conductive body 200 and the second conductive body 320 may be conductive pillars or conductive sheets, and may be made of aluminum, copper or other conductive materials.
As shown in fig. 2, 5 and 6, in one embodiment, the power supply unit 600 includes a first flexible circuit board 610 electrically connected to the first conductive body 200 and a second flexible circuit board 620 electrically connected to the second conductive body 320. As such, the first conductive body 200 and the second conductive body 320 are supplied with power using the first flexible circuit board 610 and the second flexible circuit board 620, respectively. The second flexible circuit board 620 includes a second flexible body 621, a folding portion 622 bent and extended from the second flexible body 621, and a second flexible power supply portion 623 extended from the folding portion 622 and electrically connected to an external circuit. The folding portion 622 is provided with a gap 624 along the moving direction of the mounting body 300 so as to compress or stretch along with the movement of the mounting body 300, and the second conductive body 320 is electrically connected with the second flexible body 621. So, when the installation body 300 rotates relative to the housing 100 and drives the second conductive body 320 to move, the bending portion 622 can be compressed or stretched along with the rotation of the installation body 300, so as to reduce the pulling force on the elastic reset piece 400, and prevent the elastic reset piece 400 from generating elastic fatigue and affecting the service life.
As shown in fig. 5 and 6, specifically, the folding portion 622 includes a first folding portion 6221 extending along one side of the second flexible body 621 in a direction away from the mounting body 300 and a second folding portion 6222 extending from the first folding portion 6221 to the other side of the mounting body 300. As shown in fig. 5, the first folded portion 6221 includes at least two first flat portions 6223 disposed at an interval and at least one first bent portion 6224 sequentially connecting two adjacent first flat portions 6223, and a gap 624 is formed between two adjacent first flat portions 6223. Thus, when the mounting body 300 rotates relative to the housing 100 to drive the second conductive body 320 to move, the two adjacent first flat portions 6223 are close to or away from each other, so that the whole first folding portion 6221 is compressed or stretched, and therefore the pulling degree of the second flexible circuit board 620 can be reduced, and the structural damage of the second flexible circuit board 620 caused by excessive pulling along with the movement of the mounting body 300 in the moving process is avoided.
As shown in fig. 5 and 6, the second folding portion 6222 includes at least two second flat portions 6225 disposed at an interval and at least one second folding portion 6226 sequentially connecting two adjacent second flat portions 6225, and a gap 624 is formed between two adjacent second flat portions 6225 at an interval. Like this, when the opposite side of installation body 300 also rotated around corresponding axis of rotation relative casing 100, two adjacent second flat portions 6225 drawn close each other or kept away from for whole second portion 6222 that breaks compresses or stretches, thereby can reduce the power of dragging to elasticity piece 400 that resets, avoid elasticity piece 400 to take place elasticity fatigue and influence life. In addition, the combination of the compression and the tension of the first folding portion 6221 and the second folding portion 6222 can reduce the structural damage caused by the pulling of the second flexible circuit board 620 when the mounting body 300 rotates around different rotation axes relative to the housing 100.
The first folding portion 6221 and the second folding portion 6222 may be integrally S-shaped, N-shaped or W-shaped, and only the requirement of being capable of performing corresponding compression and stretching along with the movement of the mounting body 300 is satisfied.
On the basis of any of the above embodiments, the height difference between the second connection portion 310 and the first connection portion 210 is adjustable along the axial direction of the mounting body 300. In this way, by flexibly adjusting the height difference between the second connecting portion 310 and the first connecting portion 210, the rotation angle of the mounting body 300 around the corresponding rotation axis can be flexibly adjusted, so that the mounting body 300 has a larger rotation angle. The height difference between the second connection portion 310 and the first connection portion 210 may be 0.65 mm-1.35 mm (may be 0.65mm, 0.85 mm, 0.95 mm, 1.05 mm, 1.15 mm, 1.25 mm, 1.35 mm), preferably 1.35mm, so that the rotation angle of the mounting body 300 around the corresponding rotation axis is large.
On the basis of any of the above embodiments, the orthographic projection of the elastic resetting piece 400 on the mounting body 300 forms an included angle with the rotation axis of the mounting body 300 and the elastic resetting piece 400. Thus, the contraction of the elastic reset piece 400 can drive the mounting body 300 to rotate around the corresponding rotation axis. The included angle between the orthographic projection of the elastic reset piece 400 on the mounting body 300 and the rotation axis of the mounting body 300 is greater than 0 degree and smaller than 180 degrees (30 degrees, 60 degrees, 90 degrees, 120 degrees or 150 degrees), preferably 90 degrees, so that the elastic reset piece 400 has a larger rotation angle when pulling the mounting body 300 to rotate.
The mounting body 300 is rotatably disposed in the mounting cavity 110, wherein the mounting body 300 can be directly rotatably connected to the housing 100 by a hinge or the like, or can be rotatably connected to the housing 100 by an intermediate element.
As shown in fig. 1 to 4, in one embodiment, the anti-shake module 10 further includes a connection frame 700. The mounting body 300 is coupled to the case 100 by a coupling bracket 700 so that the mounting body 300 can rotate with respect to the case 100. Thus, the connection frame 700 is used for connecting the installation body 300 and the housing 100 in a rotating manner, so that the installation body 300 is prevented from interfering with the housing 100 in the rotating process, and the rotation is smoother. The connecting frame 700 may be a sheet or a bracket structure, and only the mounting body 300 needs to rotate around the corresponding rotation axis in the mounting cavity 110.
In one embodiment, the connecting frame 700 is provided with a third connecting portion (not labeled) and a fourth connecting portion (not labeled) arranged at an included angle. The third connecting part is rotatably connected with the housing 100, and the fourth connecting part is fixedly connected with the mounting body 300; or the third connecting portion is fixedly connected with the housing 100, and the fourth connecting portion is rotatably connected with the mounting body 300. Thus, the installation body 300 can rotate around the corresponding rotation axis relative to the housing 100 only by ensuring that one of the third connection portion and the housing 100 or the fourth connection portion and the installation body 300 adopts a rotation connection mode. The third connecting portion is connected to the housing 100 in a rotating manner, and the fourth connecting portion is connected to the mounting body 300 in a rotating manner, so that the mounting body 300 can rotate relative to the housing 100 only by the rotation of the rotating shaft or the hinge connection.
As shown in fig. 3, in one embodiment, the connecting frame 700 has a fifth connecting portion 710 and a sixth connecting portion 720 arranged at an included angle, the fifth connecting portion 710 is rotatably connected to the housing 100, and the sixth connecting portion 720 is rotatably connected to the mounting body 300. Thus, when the elastic reset piece 400 is heated and contracted, under the action of the contraction force, the connecting frame 700 can rotate around the central axis of the fifth connecting portion 710 relative to the housing 100, and the mounting body 300 can rotate around the central axis of the sixth connecting portion 720 relative to the housing 100, so that the displacement deviation can be compensated, and the mounting body 300 can rotate more flexibly relative to the housing 100.
The fifth connecting portion 710 can be rotatably connected to the housing 100 through a rotating shaft or hinge, and only needs to satisfy the requirement that the connecting frame 700 can rotate around a corresponding rotation axis relative to the housing 100, so that the mounting body 300 can rotate around a corresponding rotation axis.
As shown in fig. 3 and 4, in one embodiment, the fifth connecting portion 710 includes two first connecting protrusions 711 and first rotating shafts 712 disposed in one-to-one correspondence with the first connecting protrusions 711. Two first coupling protrusions 711 are oppositely spaced and disposed toward the outside of the mounting cavity 110, and the first rotation shaft 712 is used to rotatably couple the first coupling protrusions 711 to the housing 100. In this way, the central axes of the two first rotating shafts 712 are on the same straight line to form the first straight line 713, so that the connecting frame 700 rotates around the first straight line 713 relative to the housing 100 and the mounting body 300 rotates around the first straight line 713 relative to the housing 100 under the action of the contraction force of the elastic restoring member 400, thereby compensating for the displacement deviation. A first coupling hole (not labeled) may be provided on the first coupling protrusion 711, and the first rotating shaft 712 is inserted into the first coupling hole, so that the mounting body 300 can rotate around the first straight line 713 with respect to the housing 100.
Similarly, the rotation connection between the sixth connection portion 720 and the mounting body 300 can be realized by a rotation shaft or a hinge, and only the mounting body 300 needs to rotate around the corresponding rotation axis relative to the housing 100.
As shown in fig. 3, in an embodiment, the sixth connection portion 720 includes two second connection protrusions 721 and second rotation shafts (not shown) disposed corresponding to the second connection protrusions 721 one by one, the two second connection protrusions 721 are disposed opposite to each other at intervals and facing the installation cavity 110, and the second rotation shafts are used for rotatably connecting the second connection protrusions 721 with the installation body 300. Thus, the central axes of the two second rotating shafts are on the same straight line to form a second straight line 723, and under the action of the contraction force of the elastic resetting piece 400, the connecting frame 700 also rotates around the second straight line 723 relative to the housing 100, and the mounting body 300 also rotates around the second straight line 723 relative to the housing 100, so that the displacement deviation can be compensated. In addition, the mounting body 300 can flexibly rotate around the first straight line 713 and the second straight line 723, and thus displacement compensation can be more flexibly performed. As shown in fig. 3 and 4, a second connection hole 722 may be disposed on the second connection protrusion 721, an insertion groove 330 and a third connection hole 340 communicating with the insertion groove 330 are disposed on the mounting body 300, the second connection protrusion 721 is inserted into the insertion groove 330, and the second rotation shaft is disposed in the second connection hole 722 and the third connection hole 340, so that the mounting body 300 can rotate around a second straight line 723 relative to the housing 100.
Further, as shown in fig. 3, the first straight line 713 is perpendicular or approximately perpendicular to the second straight line 723.
