Description

Driving device for camera module, camera module and terminal equipment

Technical Field

The application belongs to the camera module field, and particularly relates to a driving device for a camera module, a camera module and a terminal device.

Background

In an electronic terminal such as a mobile phone, a camera module is an essential part. In order to meet the requirement of high definition of camera shooting, the camera shooting module is required to be capable of automatically focusing, and the driving mechanism drives the lens to longitudinally move so as to realize automatic focusing.

On the one hand, due to the development requirement of lightness and thinness of the mobile phone, the installation space of the camera module is reduced and thinned. The conventional VCM motor drive includes a magnet, a coil, and the like, and can drive the lens assembly to the target position to realize the auto-focusing function, but the structure is complicated, and the structure of the camera module is increased, so that the overall size of the module structure is difficult to be reduced, and the overall miniaturization of the camera module is difficult to be realized. On the other hand, in order to meet the requirements of diversification and high definition of camera shooting, a large aperture, a large image plane and the like are introduced into the camera module, the number of lenses in the lens is continuously increased, and the quality of the lens is increased. The conventional VCM motor driving tends to have insufficient driving force, and there are also problems such as large power consumption in the conventional method. SMA (shape memory alloy) materials, due to their heat-shrinking properties, are provided as another possible actuator to replace the existing VCM drivers. The SMA actuator can meet the demand for miniaturization relative to the VCM actuator.

In addition, in the actual shooting and photographing process, the image blurring and the blurring are caused by the tiny shaking, and particularly in the shooting of a mobile phone terminal under a handheld condition, the blurring of the image caused by the shaking of the hand is more common. Therefore, an optical image stabilization system (OIS) is introduced into various high-end mobile phone terminals to solve the problem of image blurring caused by hand trembling. The principle of OIS anti-shake is that a position detection device, such as a gyroscope, detects a position offset generated by shake, calculates a displacement to be corrected according to the offset, and drives an optical anti-shake actuator to drive a corresponding direction and offset to reach a specified position, so as to compensate a corresponding position and angle, thereby overcoming the problem of image blurring caused by shake.

The existing optical anti-shake device consists of a plane moving shake-proof coil perpendicular to an optical axis, an anti-shake magnet and a suspension wire structure. For example, the optical anti-shake apparatus may include a lens section, a lens driving device for auto-focusing and shake correction, and an image pickup section. The lens driving device includes an OIS movable portion, an OIS fixed portion, and a support member, wherein the OIS movable portion is connected to the OIS fixed portion via the support member, the support member is composed of 4 suspension wires, one end of each suspension wire is fixed to the movable portion of the OIS, and the other end of each suspension wire is fixed to the OIS fixed portion. The OIS movable portion is supported by a suspension wire swingably in the XY plane.

Fig. 1 shows a schematic diagram of a camera module structure.

In an electronic terminal such as a mobile phone, as shown in fig. 1, a camera module 2000 generally includes a circuit board 2500, a photosensitive element 2400 attached to the circuit board 2500, a photosensitive element support base 2300, a lens assembly 2100, a lens carrier 1110, a driving device 1000, and a metal housing 2200. The photosensitive assembly support base 2300 includes a base for supporting the color filter and the color filter attached to the base. The lens assembly 2100 includes an optical system composed of one or more lenses, and is disposed along an optical axis with the photosensitive chip 2400 such that the optical system focuses an image on the photosensitive chip 2400, thereby implementing imaging.

Lens assembly 2100 is disposed in an inner cavity of lens carrier 1110. The driving device 1000 includes an auto-focus driving device and an optical anti-shake driving device. The auto-focus driver is connected to the lens carrier 1110 to drive the lens carrier and the lens to move up and down along the optical axis direction, thereby implementing auto-focus. The optical anti-shake driving device is arranged below the lens carrier and the automatic focusing driving device and used for driving the lens carrier, the lens assembly and the automatic focusing driving device to move on a plane vertical to an optical axis, so that shake correction is realized.

According to a first aspect of the present application, a driving device 1000 for an image pickup module is provided, as shown in fig. 2 and 3. The driving device 1000 includes: a first driving device 1100, a second driving device 1200, and an elastic supporting member 1300. According to an example embodiment of the present application, the first driving device 1100 is an SMA driving device for driving the lens assembly up and down in the optical axis direction; the second driving means 1200 is an OIS driving means for driving the lens assembly to move horizontally in a plane perpendicular to the optical axis.

Referring to fig. 2 and 3, the elastic support member 1300 is used to connect the first driving device 1100 and the second driving device 1200. As shown in fig. 3 and 4, the elastic support component 1300 includes an elastic support body 1310 and a set of elastic sheets 1320 disposed on the periphery of the elastic support body 1310. Spring plate 1320 includes a first horizontal end 1321, a second horizontal end 1322, and a vertically bent end 1324. The first horizontal end 1321 is connected to the elastic support body 1310 to extend outward from the elastic support body 1310. The vertical bent end 1324 has one end connected to the first horizontal end 1321 and the other end connected to the second horizontal end 1322. According to an example embodiment of the present application, the set of elastic pieces 1320 may be four elastic pieces disposed at four corners of the periphery of the elastic support body 1310. As shown in fig. 3, the elastic support body 1310 of the elastic support member 1300 is fixedly connected to the first driving device 1100, and the second horizontal end 1322 is fixedly connected to the second driving device 1200.

As shown in fig. 4, according to an example embodiment of the present application, the elastic support member 1300 may be a metal spring plate, for example, a plate spring. According to other exemplary embodiments of the present application, vertically bent end 1324 may include a first resilient arm and a second resilient arm. The first elastic arm and the second elastic arm are connected in an oblique and crossed mode, namely the first elastic arm and the second elastic arm are located on different planes. For example, the first elastic arm and the second elastic arm are perpendicular to each other by the L-shaped horizontal connecting portion 1323. The first or second resilient arm may comprise at least one U-shaped resilient arm.

Referring to fig. 4, in the exemplary embodiment of the present application, the number of the U-shaped elastic arms is two, and the number of the U-shaped elastic arms may be set according to needs, which is not limited in the present application. The vertical bent end 1324 is connected by bending for many times, so that the deformation strength of the supporting member is increased, and the reliability can be improved, thereby allowing the first driving device 1100 to move on a plane relative to the second driving device 1200 as a whole, and preventing the elastic supporting member 1300 from being twisted and bent to affect the supporting stability.

As shown in fig. 3, the SMA actuation apparatus 1100 includes a lens carrier 1110, an upward SMA actuator 1130, a downward SMA actuator 1140, a base 1160, and a first fixed support member 1170 disposed on the base 1160. Wherein the first fixed supporting member 1170 is fixedly connected to the elastic supporting body 1310 of the elastic supporting member 1300. According to some embodiments of the present application, the elastic support member 1300 may be fixed to the first stationary bearing member through at least three support points. According to an exemplary embodiment of the present application, the first stationary support 1170 may be a set of positioning posts disposed on the base 1160, and the number thereof may be determined according to requirements, for example, 4.

The first driver 1130 and the second driver 1140 are connected to the lens carrier 1110, and the first driver 1130 drives the lens carrier 1100 to move upward along the optical axis direction of the camera module; the second driver 1140 drives the lens carrier 1100 to move downward along the optical axis direction of the camera module.

According to an example embodiment of the present application, the lens carrier 1110 includes a carrier body 1111 and a carrier cavity 1112, with a lens assembly being held in the carrier cavity 1112 by the carrier body 1111. The carrier body 1111 is further provided with a carrier inner wall having a shape corresponding to the outer circumferential shape of the lens module.

The carrier body 1111 further includes a carrier ring 1114 and a carrier support 1115, wherein the carrier support 1115 is integrally provided to the outer circumference of the carrier ring 1114. The first and

second actuators

1130 and 1140 provide upward and downward forces on the carrier ring 1114 through the carrier support 1115 to drive the lens carrier 1110 upward or downward.

The carrier body 1111 further includes a first bending block 1116 and a second bending block 1117, which are disposed around the carrier support 1115 and are configured to cooperate with the first actuator 1130 and the second actuator 1140, respectively, to drive the lens carrier 1110 to move up and down.

The lens carrier 1110 further includes a first stop 1118 for limiting the maximum distance the lens carrier 1110 is driven to move upward. The first stopper 1118 may extend upwardly from the top surface of the carrier 1115, and may be integrally formed with the carrier 1115.

The lens carrier 1110 further includes a spacer 1119 disposed around the carrier support 1115 for spacing the lens carrier 1110 from an inner wall of the camera module housing. The spacer 1119 is integrally disposed on the lens carrier 1110, and may be integrally extended outward from the side of the carrier support 1115, and protrude outward from the positions of the first actuator 1130 and the second actuator 1140, so as to limit the SMA wires of the first actuator 1130 and the second actuator 1140 from contacting the housing of the camera module.

The first driver 1130 includes a first SMA drive wire 1131 and a first fixture 1132, wherein both ends of the first SMA drive wire 1131 are disposed on the first fixture 1132, and the first driver 1130 is fixed to the base 1160 by the first fixture 1132. The first SMA drive line 1131 of the first actuator 1130 is disposed below the first flexure block 1116, wherein the first SMA drive line 1131 of the first actuator 1130 is thermally driven to contract and pull up, thereby pushing the first flexure block 1116 upward.

The second driver 1140 includes a second SMA driving wire 1141 and a second fixing device 1142, wherein two ends of the second SMA driving wire 1141 are disposed on the second fixing device 1142, and the second driver 1140 is fixed on the base 1160 by the second fixing device 1142. A second SMA drive wire 1141 of the second driver 1140 is disposed below a second flexure block 1117, where the second SMA drive wire 1141 contracts in a thermally driven manner drawing the second flexure block 1117 downward.

It should be noted that the SMA wire is heated by itself or by a heat source to achieve the thermal driving. That is, the SMA wire may be heated by itself or by another heat source to contract the length of the SMA wire and thereby drive movement of the movable member. Preferably, in the first preferred embodiment of the present invention, the SMA wire is thermally driven by self-heating, and the SMA wire driving force is controlled by controlling the SMA wire current. In short, when the current of the SMA wire increases, the temperature of the SMA wire heated by electricity increases, and the SMA wire contracts thermally, so that the driving force of the SMA wire increases; when the SMA wire current is reduced, the temperature of the SMA wire which is electrically heated is reduced or the temperature of the SMA wire is reduced at the ambient temperature, and the SMA wire is relaxed, so that the driving force of the SMA wire is reduced.

According to an example embodiment of the present application, the height of the first fixture 1132 is greater than the height of the second fixture 1142. Wherein the first fixture 1132 supports both ends of the first SMA drive wire 1131 such that the first SMA drive wire 1131 passes around the first bending block 1116 to form a "V" shaped traction structure. Accordingly, the first fixture 1142 supports both ends of the second SMA drive wire 1141 such that the first SMA drive wire 1141 bypasses the second flexure 1117 to form an inverted "V" shaped tow structure. Thus, the first driver 1130 and the second driver 1140 of the SMA actuation apparatus 1100 provide mutually opposite forces to the lens carrier 1110, and the lens assembly is moved up and down by driving the lens carrier 1110.

As shown in fig. 2 and 3, the elastic support body 1310 of the elastic support member 1300 is disposed above the lens carrier 1110. The SMA actuation apparatus 1100 further includes a second resilient piece (not shown) disposed on the base 1610, disposed below the lens carrier 1110, and supporting the lens carrier 1110. In a static non-energized state, the elastic support body 1310 and the second elastic sheet support the lens carrier 1110 together, and the lens is maintained at a central position by the lens carrier 1110. When the lens carrier 1110 is driven upwards or downwards by the SMA drive apparatus 1100, the elastic support body 1310 and the second resilient sheet balance the support acting force applied to the lens carrier 1110 in each direction, so that the driving acting force applied to the lens carrier 1110 in each direction is the same, thereby maintaining the smoothness of the lens assembly moving during the driving process through the lens carrier 1110.

The elastic support body 1310 includes a spring ring 1311 and an extension 1312 extending outward from the spring ring 1311. Wherein the clip ring 1311 is disposed on the carrier ring 1114 of the lens carrier 1110, and is sized to fit to the carrier ring 1114. According to some embodiments of the present disclosure, the elastic support body 1310 is a sheet-like elastic body having a hollow structure, and can bear a certain force and return to its original shape under the action of elasticity. The resilient support body 1310 may be formed by mechanical stamping or etching.

In the initial state, the elastic support body 1310 is in a natural extension state, in which the elastic ring 1311 and the extension 1312 are in the same horizontal plane. When the clip ring 1311 is driven to move upward by the lens carrier 1110, the intermediate connection portion of the clip ring 1311 and the extension 1312 is elastically deformed. The extension portion 1312 provides a downward elastic force to the lens carrier 1110.

The second elastic sheet also comprises an elastic sheet ring and a supporting end which is formed by extending outwards from the elastic sheet ring. The elastic ring of the second elastic piece is arranged below the carrier ring 1114 of the lens carrier 1110, the size of the elastic ring is adapted to the carrier ring 1114, and the elastic ring of the second elastic piece provides upward supporting force for the lens carrier 1110. According to an example embodiment of the present application, the second elastic sheet is also a sheet-like elastic body with a hollow structure, and may be made by mechanical stamping or etching. According to an example embodiment of the present application, the elastic supporting body 1310 and the second elastic sheet may be elastic devices made of metal.

In an initial state, the lens carrier 1110 is supported upward by the elastic ring of the second elastic piece under the supporting action of the base 1160, and the lens assembly is positioned at a middle position by the lens carrier 1110. When the second actuator 1140 of the SMA actuation apparatus 1100 drives the lens carrier 1110 to move downward, the lens carrier 1110 presses the elastic ring of the second elastic piece downward, so that the support end of the second elastic piece is elastically deformed. The supporting end of the second elastic sheet supports the lens carrier 1110, and the stress of each part in the horizontal direction is balanced. The elastic ring of the second elastic piece provides an upward elastic force to the lens carrier 1110 to support the lens carrier 1110 to move upward and return to the middle position from the lower part.

As shown in fig. 3, the base 1160 includes a base body 1161, a first fixing support member 1170 disposed on the base body 1161, and a second limiting device 1163. The first fixed supporting part 1170 is fixedly coupled to the elastic supporting body 1310 of the elastic supporting part 1300, for example, to four corners of the elastic supporting body 1310. The second limiting means 1163 may be integrally extended upward from the upper surface of the base main body 1161. The distance between the second limiting device 1163 and the lens carrier 1110 is the limit distance for the lens assembly to move downwards. When the lens carrier 1110 is driven to move downward by the second driver 1140, the lens carrier 1110 is moved downward to contact the second stopper 1163 by the maximum mechanical stroke of the lens carrier 1110 downward.

In the camera module, the OIS drive 1200 is located below the SMA drive 1100. As shown in fig. 3, the OIS driver 1200 includes a substrate 1210, a set of coils 1220, a set of magnetic bodies 1230, and a second stationary support member 1240. A set of magnetic bodies 1230 are connected to the base 1610 of the SMA actuation apparatus. The set of coils 1220 is disposed on the substrate 1210 and is disposed opposite to the set of magnetic bodies 1230. The OIS driver apparatus 1200 further includes a position sensing element (not shown) disposed on the substrate 1210 adjacent to the set of coils 1220. The position sensing element can sense the position of the lens component of the camera module. According to the position information obtained by the sensing element, the SMA driving device can be driven and the lens assembly can be driven to horizontally move in the direction perpendicular to the optical axis of the camera module by the magnetic force between the group of coils 1220 and the group of magnetic bodies 1230, so that the shake correction is realized.

According to some embodiments of the present application, the number of the set of magnetic bodies 1230 and the set of coils 1220 may be four, respectively disposed at four corners of the substrate 1210. The magnetic body may be a magnet, or the like. The set of magnetic bodies 1230 and the set of coils 1220 together constitute an OIS drive structure.

The second fixed support member 1240 is fixedly coupled to the second horizontal end 1322 of the elastic support member 1300. According to some embodiments of the present disclosure, the second fixing support component 1240 may be a set of positioning pillars, and the positions and the number of the positioning pillars may be set according to the requirements, corresponding to the positions and the number of the set of elastic sheets 1320.

The SMA drive device 1100 and the OIS drive device 1200 are suspended and elastically supported by the elastic support part 1300, so that the SMA drive device 1100 can be allowed to move up and down in the optical axis direction within a certain range relative to the OIS drive device 1200, and automatic focusing is realized; and allows the SMA drive apparatus 1100 to move horizontally relative to the OIS drive apparatus 1200 in a direction perpendicular to the optical axis to effect shake correction. Also, the structure of the elastic support member 1300 is more stable and the assembly process is simple, compared to the suspension structure, so that the production cost can be reduced while the function is ensured.

According to another aspect of the present application, there is provided a camera module 3000, as shown in fig. 5 and 6, including a lens assembly 2100, a driving device 1000, a lens mount 3100, and a housing 2200. Wherein the lens assembly 2100 is connected to the lens carrier 1100 of the drive device 1000. The lens assembly 2100 and the driving device 1000 are disposed within the housing 2200. The lens mount 3100 is disposed under the housing 2200 to be coupled to and support the driving device 1000. The driving device 1000 drives the lens assembly 2100 to move up and down in the housing 2200 to achieve auto-focusing and horizontal movement to achieve shake correction.

The housing 2200 has an accommodating space 2210 and a light inlet hole 2220, wherein the light inlet hole 2220 is formed at an upper portion of the housing 2200 in communication with the accommodating space 2210. Light enters the lens assembly 2100 through the light inlet 2220, so that the lens assembly 2100 receives light incident from the outside.

The lens base 3100 further includes a circuit board 2500, a photosensitive element 2400 attached to the circuit board 2500, a photosensitive element support 2300, and a color filter 2600 disposed on the photosensitive element support 2300.
