[0079] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0080] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0081] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0082] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0083] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0084] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would subsequently be positioned "over" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0085] The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive.

The shaft portion 205 provides guidance for the support mechanism 204 so as to stably move the support mechanism 204 up and down. Accordingly, a hollow portion is provided inside the support mechanism 204 to accommodate the shaft portion 205.

[0100] Through the lifting device 200 , when the camera module 100 needs to be extended or retracted into the housing 300 , the motor 201 is used to drive the camera module 100 stably.

[0104] The camera module 100 may further include a support portion 102 . The support portion 102 is fixedly connected to the camera module 101 and is used to support the camera module 101 .

[0105] The camera module 100 may further include a rotation control unit 110 for controlling the pitch angle of the camera module 101 by controlling the support unit 102 .

[0106] The rotation control unit 110 includes a piezoelectric control device, and the pitch angle of the camera module 101 is controlled by controlling the support unit 102 through the piezoelectric control device. The piezoelectric control device is accommodated in the frame of the camera system.

[0107] The rotation control unit 110 further includes a rotation axis O, and the support unit 102 can be controlled to rotate around the rotation axis O, thereby driving the camera module 101 to rotate.

[0108] The piezoelectric control device may include a ceramic plate 111 , a piezoelectric element 112 , and a rod 113 .

[0109] The ceramic plate (piezoelectric ceramic plate) 111 is arc-shaped and is disposed at one end of the support portion 102 that is not fixedly connected to the camera module 101. The ceramic plate 111 is arc-shaped and is located on a concentric circle with the rotation axis O as the center.

[0110] The piezoelectric element 112 is fixed to the housing 105 that accommodates the piezoelectric control device.

[0111] The rod-shaped member 113 is fixed to the piezoelectric element 112 , wherein the rod-shaped member 113 is moved by the deformation of the piezoelectric element 112 , and the support portion 102 is rotated by the contact and friction between the rod-shaped member 113 and the ceramic plate 111 .

[0112] The piezoelectric control device further includes an elastic member 114 , such as elastic rubber, and the elastic member 114 is disposed between the piezoelectric element 112 and the housing 105 .

[0113] According to a further embodiment of the present disclosure, a housing 105 is further included, wherein a portion of the support portion 102 and the rotation control portion 110 are disposed in the housing 105 , and a space for the support portion 102 to rotate is reserved on the upper side of the housing 105 .

[0114] Reference Figure 4 , provides a schematic diagram of a portion of the rotation control unit 110 according to one embodiment of the present disclosure, wherein Figure 4 (a) shows a plan view of the rotation control unit, Figure 4 (b) shows a side view of the plan view, Figure 4 (c) shows a bottom view of the plan view.

[0115] like Figure 4 As shown, the rotation control unit 110 may include a piezoelectric element 112 and a rod-shaped member 113 .

[0116] The piezoelectric element 112 may be composed of four parts, and the specific composition will be described in detail below.

[0117] The rod-shaped member 113 may be made of metal, may be in the shape of a round rod, and may be disposed on the piezoelectric element 112 .

[0118] A groove 115 may be provided at the rod-shaped member of the piezoelectric element 112. The groove 115 may be triangular or in other shapes. The groove 115 is used to accommodate a portion of the rod-shaped member 113, and the groove 115 may be filled with a viscous resin so as to fix the rod-shaped member 113 to the piezoelectric element 112.

[0119] When the piezoelectric element 112 is energized and deformed, it will drive the rod-shaped member 113 to move. Figure 5 Explain it.

[0120] exist Figure 5 , a schematic diagram of the operation of the rotation control unit 110 is shown. The piezoelectric element 112 includes four parts: a first part 112a, a second part 112b, a third part 112c and a fourth part 112d.

[0122] According to a further embodiment, Figure 3 and 7 As shown, the camera module 101 may further include a blocking member 106, which limits the rotation range of the support portion 102, thereby limiting the rotation range of the lens.

[0123] The blocking member 106 limits the rotation angle of the supporting portion 102 to limit the maximum deviation angle between the optical axis direction of the lens of the camera module 101 and the initial optical axis direction. Figure 7 As shown in FIG. 7 , the rotation range can be limited by the upper surface of the piezoelectric ceramic 111 abutting against the stopper 106. Figure 7 The blocking member 106 is used to limit the leftward rotation, but those skilled in the art should understand that when limiting the rotation to the right, a corresponding blocking member can also be provided, and the same distance can be adopted. A blocking member can also be provided to reach the initial optical axis direction.

[0124] The blocking member 106 may be in the form of a fixed block, for example, may be fixedly disposed on the housing 105 .

[0125] Figure 8 The figure shows that by applying a high-period wave (rectangular wave) signal to the piezoelectric element, the piezoelectric element generates ultrasonic vibration, thereby driving the rod-shaped member to move, and the rod-shaped member provides the traveling wave to the piezoelectric ceramic, thereby causing the support part to rotate. Figure 8 It can be seen from the figure that the rotation direction of the support part is different when the applied signal is different.

[0126] According to an optional embodiment of the present disclosure, the blocking member 106 (leftward limitation) and / or another blocking member (rightward limitation or initial limitation) can be replaced by a first position detection unit and / or a second position detection unit, and the first position detection unit and the second position detection unit detect the rotation angle of the support unit 102, wherein the first position detection unit is configured to detect that the optical axis direction of the lens of the camera module 101 is in a state where ... initial optical axis direction has a maximum deviation angle on the right side (initial optical axis direction).

[0127] In a specific application, the first position detection unit and the second position detection unit are Hall sensors or limit switches, and the signal of the piezoelectric element is controlled according to the detection signal of the first position detection unit and / or the second position detection unit.

[0128] The following is a specific description using the Hall sensor as an example. For example, a Hall element is provided on the housing 105, and a permanent magnet is provided on the support part 102. When it is necessary to return to the initial optical axis direction, the current of the SMA spring is controlled. When the Hall element of the first position detection part detects that the support part is in place, the piezoelectric element is controlled to stabilize it to the initial optical axis direction. When it is necessary to reach the maximum rotation angle, the current of the piezoelectric element is controlled. When the Hall element of the second position detection part detects that the support part is in place, the piezoelectric element is controlled to stabilize it to the maximum rotation angle.

[0129] In a further embodiment of the present disclosure, for example, in the case of a telephone conference, the positions of conference participants can be automatically detected, and the first and second telescopic mechanisms can be controlled according to the detected positions to achieve rotation of the lens.

[0130] The present disclosure also provides an electronic device, comprising the above-mentioned camera system.

[0131] According to the embodiments of the present disclosure, the angle of the lens can be arbitrarily changed, and a thin angle control actuator can be provided, so that it can be used in a thin portable terminal or the like.
