背景技术Background technique

目前随着电子设备的发展，人们常常通过电子设备拍摄图像。随着人们需求的提高，对图像的质量要求也越来越高。With the development of electronic devices, people often take images through electronic devices. As people's needs increase, the requirements for image quality are getting higher and higher.

If there is jitter in the shooting process, the drive structure cannot automatically adjust the position of the lens, which will make the quality of the captured image poor, that is, the current drive structure has a poor anti-shake function.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

请参见图1，本实施例提供一种驱动装置，包括载体1、壳体2、弹性件3、至少两个电致驱动片4和底座5；Referring to FIG. 1, this embodiment provides a driving device, which includes a carrier 1, a housing 2, an elastic member 3, at least two electro-driven plates 4, and a base 5;

所述载体1通过所述弹性件3与所述壳体2活动连接，且所述载体1用于承载功能器件；The carrier 1 is movably connected to the housing 2 through the elastic member 3, and the carrier 1 is used to carry functional devices;

所述至少两个电致驱动片4中的各电致驱动片4的第一端与所述底座5相连接，各所述电致驱动片4的第二端与所述载体1相连接；The first end of each electro-driven piece 4 of the at least two electro-driven pieces 4 is connected with the base 5, and the second end of each electro-driven piece 4 is connected with the carrier 1;

其中，在对所述至少两个电致驱动片4中的至少一个电致驱动片施加电压的情况下，所述至少一个电致驱动片变形以驱动所述载体1运动。Wherein, when a voltage is applied to at least one of the at least two electro-driving sheets 4, the at least one electro-driving sheet is deformed to drive the carrier 1 to move.

具体的，载体1通过所述弹性件3与所述壳体2活动连接，即载体1可以相对于壳体2运动，例如，弹性件3设置在壳体2上，载体1与弹性件3连接，悬置在容置腔体中，载体1可在容置腔体内运动。载体1用于承载功能器件，载体1与功能器件之间可采用可拆卸连接，例如，螺纹连接或卡接，功能器件可为光学器件。例如，光学器件可以为应用于摄像头、红外传感器、闪光灯等器件的透镜(lens)或透镜组件，可以通过驱动装置来调节光学器件输出或接收光信号的光程、光学器件的发散角以及焦点等光学参数；功能器件还可为声学模组，可以通过驱动装置调节声学模组的位置，从而改变声学模组前腔或后腔的体积，以改变声学模组的音频特性等等；功能器件还可以是其他的一些活动器件，如触控笔、接口或卡托等结构，此种情况下，驱动装置为活动器件弹出的驱动结构。Specifically, the carrier 1 is movably connected to the housing 2 through the elastic element 3, that is, the carrier 1 can move relative to the housing 2. For example, the elastic element 3 is provided on the housing 2, and the carrier 1 is connected to the elastic element 3. , Suspended in the accommodating cavity, the carrier 1 can move in the accommodating cavity. The carrier 1 is used to carry a functional device, and a detachable connection may be adopted between the carrier 1 and the functional device, for example, a threaded connection or a snap connection, and the functional device may be an optical device. For example, the optical device can be a lens or lens assembly applied to a camera, an infrared sensor, a flashlight, etc., and a driving device can be used to adjust the optical length of the optical device output or receive the optical signal, the divergence angle and focus of the optical device, etc. Optical parameters; the functional device can also be an acoustic module, the position of the acoustic module can be adjusted by the driving device, thereby changing the volume of the front cavity or the back cavity of the acoustic module to change the audio characteristics of the acoustic module, etc.; the functional device is also It can be some other movable devices, such as a stylus, interface, or a card holder. In this case, the driving device is a driving structure for ejecting the movable device.

对于每个电致驱动片4，电致驱动片4的第一端与所述底座5相连接，以固定在底座5上，电致驱动片4的第二端与所述载体1相连接。对于每个电致驱动片4，当对所述电致驱动片4施加电压时，所述电致驱动片4变形并驱动所述载体1运动，例如，根据电致驱动片4的形变方向不同，可驱动所述载体1在朝向底座或背离底座的方向上运动。For each electro-driven piece 4, the first end of the electro-driven piece 4 is connected with the base 5 to be fixed on the base 5, and the second end of the electro-driven piece 4 is connected with the carrier 1. For each electro-driving sheet 4, when a voltage is applied to the electro-driving sheet 4, the electro-driving sheet 4 deforms and drives the carrier 1 to move, for example, according to the direction of deformation of the electro-driving sheet 4 , The carrier 1 can be driven to move in a direction toward or away from the base.

所述电致驱动片4变形，以使所述弹性件3驱动所述载体1运动，即电致驱动片4变形反向回缩时，在弹性件3的作用下，驱动载体1反向运动。The electro-driving sheet 4 is deformed so that the elastic member 3 drives the carrier 1 to move, that is, when the electro-driving sheet 4 deforms and retracts in the reverse direction, the elastic member 3 drives the carrier 1 to move in the reverse direction. .

需要说明的是，载体1悬置时，弹性件3和电致驱动片4可以共同对载体1提供作用力，使其维持悬置状态，此时弹性件3可以不处于初始状态，即弹性件3处于压缩状态或者拉伸状态，具有一定的弹性势能。在电致驱动片4通电产生变形，且沿背离底座5的一侧弯折的情况下，电致驱动片4驱动载体1向远离底座5的方向运动，此时弹性件3被压缩。It should be noted that when the carrier 1 is suspended, the elastic member 3 and the electro-driven sheet 4 can jointly provide a force to the carrier 1 to maintain the suspended state. At this time, the elastic member 3 may not be in the initial state, that is, the elastic member 3 It is in a compressed or stretched state and has a certain elastic potential energy. When the electro-driven sheet 4 is energized and deformed and bends along the side away from the base 5, the electro-driven sheet 4 drives the carrier 1 to move away from the base 5, and the elastic member 3 is compressed at this time.

在电致驱动片4通电产生变形，且沿朝向底座5的一侧弯折的情况下，则有可能存在以下两种情况：When the electro-driven sheet 4 is energized and deformed and is bent along the side facing the base 5, there may be the following two situations:

电致驱动片4带动载体1向靠近底座5的方向运动，同时弹性件3被拉伸，此种情况的前提为：载体1处于悬置状态时，弹性件3处于原长或者拉伸状态；The electro-driven sheet 4 drives the carrier 1 to move in a direction close to the base 5 while the elastic member 3 is stretched. The premise of this situation is: when the carrier 1 is in a suspended state, the elastic member 3 is in the original length or stretched state;

弹性件3驱动载体1向靠近底座5的方向运动，此种情况针对在载体1处于悬置状态时，弹性件3处于压缩状态的情况。The elastic member 3 drives the carrier 1 to move in a direction close to the base 5. This situation is directed to the situation where the elastic member 3 is in a compressed state when the carrier 1 is in a suspended state.

本实施例包括至少两个电致驱动片4，可通过对至少两个电致驱动片4中的一个或多个电致驱动片4施加电压，使得这一个或多个电致驱动片4发生形变，对载体1产生作用力，从而驱动载体1运动，载体1的运动可以是发生角度倾斜的运动和在垂直方向上运动一段距离的至少一项，其中，垂直方向可为朝向或者背离底座5运动的方向。This embodiment includes at least two electro-driven plates 4, which can be caused by applying a voltage to one or more of the at least two electro-driven plates 4 Deformation generates a force on the carrier 1 to drive the carrier 1 to move. The movement of the carrier 1 can be at least one of angular tilt and a distance in the vertical direction, where the vertical direction can be toward or away from the base 5. The direction of movement.

FIG. 20, FIG. 23, and FIG. 24 are schematic diagrams of the cross-sectional structure of the driving device provided in this embodiment.

进一步的，所述至少两个电致驱动片4均为离子传导驱动片，所述离子传导驱动片包括离子交换树脂层以及分别设置于所述离子交换树脂层相对的两个表面的第一电极层和第二电极层，所述离子交换树脂层内具有聚合物电解质。Further, the at least two electro-driving sheets 4 are both ion-conducting driving sheets, and the ion-conducting driving sheets include an ion exchange resin layer and first electrodes respectively disposed on two opposite surfaces of the ion exchange resin layer. Layer and a second electrode layer, the ion exchange resin layer has a polymer electrolyte in it.

具体的，电致驱动片4可采用离子交换聚合金属材料(ion-exchange polymer metal composite，IPMC)制作。IPMC材料是一种新型电致动功能材料，以离子交换树脂层(如氟碳聚合物等)为基体，在基体表面镀贵金属(如铂、银等)，以形成电极层，即第一电极层和第二电极层，如图25所示，图25中标号A和标号B所示分别为第一电极层和第二电极层。离子交换树脂层包括聚合物电解质，聚合物电解质中含有阳离子和阴离子，图25中阳离子和阴离子的位置及数量仅为示意，不代表实际情况。Specifically, the electro-driven sheet 4 may be made of ion-exchange polymer metal composite (IPMC). IPMC material is a new type of electrically actuated functional material. It uses ion exchange resin layer (such as fluorocarbon polymer, etc.) as a matrix, and plating precious metals (such as platinum, silver, etc.) on the surface of the substrate to form an electrode layer, that is, the first electrode The layer and the second electrode layer, as shown in FIG. 25, are the first electrode layer and the second electrode layer as shown by the reference numeral A and the reference numeral B in FIG. 25, respectively. The ion exchange resin layer includes a polymer electrolyte. The polymer electrolyte contains cations and anions. The positions and quantities of the cations and anions in FIG. 25 are only indicative, and do not represent the actual situation.

如图26、图27所示，当对IPMC在厚度方向施加电压时，聚合物电解质中的水合阳离子会移动到阴极侧，引起IPMC的阳极面和阴极面溶胀的差异，从而产生变形，向阳极面弯曲，这样，可通过控制IPMC的通电电压或者电流来控制IPMC弯曲程度，使得IPMC在横向方向上产生位移。As shown in Figure 26 and Figure 27, when a voltage is applied to the IPMC in the thickness direction, the hydrated cations in the polymer electrolyte will move to the cathode side, causing the difference in swelling between the anode surface and the cathode surface of the IPMC. The surface is curved. In this way, the degree of bending of the IPMC can be controlled by controlling the energized voltage or current of the IPMC, so that the IPMC is displaced in the lateral direction.

IPMC材料为一种新型驱动材料，具有驱动质轻、产生位移形变大、驱动电压低等优点。驱动装置中采用IPMC的优势明显，例如，IPMC为非磁性材料，不会产生磁干扰；IPMC变形产生的位移和速度与IPMC的厚度成比例地减小，IPMC变形产生的力与IPMC的厚度的立方成比例地增大。因此，可根据实际情况来设置IPMC的厚度，以达到所需的IPMC变形产生的位移、速度和力度。IPMC material is a new type of driving material, which has the advantages of light driving, large displacement deformation, and low driving voltage. The advantages of using IPMC in the driving device are obvious. For example, IPMC is a non-magnetic material and will not cause magnetic interference; the displacement and speed generated by IPMC deformation are reduced in proportion to the thickness of IPMC, and the force generated by IPMC deformation is less than the thickness of IPMC. The cube increases proportionally. Therefore, the thickness of the IPMC can be set according to the actual situation to achieve the required displacement, speed and strength due to the deformation of the IPMC.

进一步的，在施加于所述离子传导驱动片的电压为第一电压的情况下，所述离子传导驱动片驱动所述载体1沿第一方向运动；在施加于所述离子传导驱动片的电压为第二电压的情况下，所述离子传导驱动片驱动所述载体1沿第二方向运动；其中，所述第一电压和所述第二电压极性相反，所述第一方向与所述第二方向互为反方向。通过向离子传导驱动片施加极性相反的电压，可使得离子传导驱动片驱动所述载体1沿第一方向或第二方向运动。第一方向可为载体1朝向壳体2运动的方向，第二方向可为载体1背离壳体2运动的方向；第一方向可为载体1背离壳体2运动的方向，第二方向可为载体1朝向壳体2运动的方向。Further, when the voltage applied to the ion conduction drive sheet is the first voltage, the ion conduction drive sheet drives the carrier 1 to move in the first direction; when the voltage applied to the ion conduction drive sheet In the case of the second voltage, the ion conduction drive plate drives the carrier 1 to move in a second direction; wherein the first voltage and the second voltage have opposite polarities, and the first direction is opposite to the The second direction is opposite to each other. By applying voltages with opposite polarities to the ion conduction drive plate, the ion conduction drive plate can drive the carrier 1 to move in the first direction or the second direction. The first direction may be the direction in which the carrier 1 moves toward the housing 2, and the second direction may be the direction in which the carrier 1 moves away from the housing 2; the first direction may be the direction in which the carrier 1 moves away from the housing 2, and the second direction may be The carrier 1 faces the direction in which the housing 2 moves.

进一步的，在施加于所述离子传导驱动片的电压为第一电压的情况下，所述离子传导驱动片驱动所述载体1沿第一方向运动第一距离；在施加于所述离子传导驱动片的电压为第三电压的情况下，所述离子传导驱动片驱动所述载体1沿第一方向运动第二距离；其中，所述第一电压和所述第三电压极性相同，且所述第三电压大于所述第一电压，所述第一距离与所述第二距离不同。Further, when the voltage applied to the ion conduction drive sheet is the first voltage, the ion conduction drive sheet drives the carrier 1 to move in the first direction for a first distance; When the voltage of the sheet is the third voltage, the ion conduction drive sheet drives the carrier 1 to move a second distance in the first direction; wherein the first voltage and the third voltage have the same polarity, and The third voltage is greater than the first voltage, and the first distance is different from the second distance.

第二距离可大于第一距离。当需要载体1运动较大距离时，可通过向离子传导驱动片施加较大电压来驱动载体1运动较大距离；当需要载体1运动较小距离时，可通过向离子传导驱动片施加较大电压来驱动载体1运动较小距离。施加于离子传导驱动片的电压大小与载体1的运动距离之间具有对应关系，在确定载体1需要运动的距离的情况下，可根据该对应关系来确定施加于离子传导驱动片的电压大小。进一步的，在施加于所述离子传导驱动片的电压为第一电压的情况下，所述离子传导驱动片以第一速率驱动所述载体1沿第一方向运动；在施加于所述离子传导驱动片的电压为第三电压的情况下，所述离子传导驱动片以第二速率驱动所述载体1沿第一方向运动；其中，所述第一电压和所述第三电压极性相同，且所述第三电压大于所述第一电压，所述第一速率与所述第二速率不同。The second distance may be greater than the first distance. When the carrier 1 is required to move a larger distance, a larger voltage can be applied to the ion conduction drive plate to drive the carrier 1 to move a larger distance; when the carrier 1 is required to move a smaller distance, a larger distance can be applied to the ion conduction drive plate. The voltage drives the carrier 1 to move a small distance. There is a corresponding relationship between the magnitude of the voltage applied to the ion-conducting drive sheet and the moving distance of the carrier 1. In the case of determining the distance that the carrier 1 needs to move, the magnitude of the voltage applied to the ion-conducting drive sheet can be determined according to the correspondence. Further, when the voltage applied to the ion conduction drive sheet is the first voltage, the ion conduction drive sheet drives the carrier 1 to move in the first direction at a first rate; When the voltage of the driving plate is the third voltage, the ion conduction driving plate drives the carrier 1 to move in the first direction at a second rate; wherein the first voltage and the third voltage have the same polarity, And the third voltage is greater than the first voltage, and the first rate is different from the second rate.

第二速率可小于第一速率。当需要载体1运动速率较大时，可通过向离子传导驱动片施加较大电压来驱动载体1以较大速率进行运动；当需要载体1运动速率较小时，可通过向离子传导驱动片施加较小电压来驱动载体1以较小速率进行运动。施加于离子传导驱动片的电压大小与载体1的运动速率之间具有对应关系，在确定载体1需要运动的速率的情况下，可根据该对应关系来确定施加于离子传导驱动片的电压大小。The second rate may be less than the first rate. When the speed of the carrier 1 needs to be large, the carrier 1 can be driven to move at a larger speed by applying a large voltage to the ion conduction drive sheet; when the speed of the carrier 1 needs to be small, the carrier 1 can be applied to the ion conduction drive sheet. The small voltage drives the carrier 1 to move at a small speed. There is a corresponding relationship between the magnitude of the voltage applied to the ion-conducting drive plate and the movement rate of the carrier 1. In the case of determining the velocity at which the carrier 1 needs to move, the magnitude of the voltage applied to the ion-conducting drive plate can be determined according to the correspondence relationship.

当需要载体1产生较大角度的倾斜时，可通过向离子传导驱动片施加较大电压来驱动载体1产生较大角度的倾斜；当需要载体1产生较小角度的倾斜时，可通过向离子传导驱动片施加较小电压来驱动载体1产生较小角度的倾斜。施加于离子传导驱动片的电压大小与载体1的倾斜角度之间具有对应关系，在确定载体1需要倾斜的角度的情况下，可根据该对应关系来确定施加于离子传导驱动片的电压大小。进一步的，本申请实施例还提供一种电子设备，包括上述所述的驱动装置。When the carrier 1 is required to generate a larger angle of inclination, the carrier 1 can be driven to generate a larger angle of inclination by applying a larger voltage to the ion conduction drive sheet; when the carrier 1 is required to generate a smaller angle of inclination, the ion The conductive drive plate applies a small voltage to drive the carrier 1 to generate a small angle of inclination. There is a corresponding relationship between the magnitude of the voltage applied to the ion-conducting drive sheet and the tilt angle of the carrier 1. In the case of determining the angle at which the carrier 1 needs to be tilted, the magnitude of the voltage applied to the ion-conducting drive sheet can be determined according to the correspondence relationship.
