In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The camera module provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

As shown in FIGS. 1 to 18 , the embodiment of the present application provides a camera module, which includes a casing 100 , a lens 200 , a suspension assembly 300 and a driving mechanism 400 .

The casing 100 provides the installation base for other components of the camera module, and the casing 100 can protect its internal components from the interference of the external environment.

The lens 200 is installed in the casing 100, and the lens 200 can be fixed relative to the casing 100. It can specifically include a lens barrel and a number of lenses installed in the lens barrel. The lenses can be made of one or more curved optical glass or Optical components made of plastic parts. The lens 200 can focus light to facilitate imaging. One end of the lens 200 can be located outside the housing 100 , that is, the light incident surface of the lens 200 is located outside the housing 100 , so that external light can enter the camera module smoothly.

The suspension assembly 300 is suspended in the casing 100. The suspension assembly 300 includes a circuit board 310 and an image sensor 320. The image sensor 320 is arranged on the circuit board 310. The image sensor 320 is arranged opposite to the lens 200. The light passing through the lens 200 can irradiate the image On the sensor 320, the image sensor 320 can convert light signals into electrical signals.

The driving mechanism 400 is disposed in the casing 100 , the driving mechanism 400 is located between the casing 100 and the suspension assembly 300 , the driving mechanism 400 is connected with the circuit board 310 , and drives the circuit board 310 to move. When shooting, when the user's hand shakes and the whole camera module shakes, the driving mechanism 400 drives the circuit board 310 to move, so as to achieve the purpose of anti-shaking of the camera module.

In the embodiment of the present application, the image sensor 320 is installed on the circuit board 310. When shooting, the driving mechanism 400 moves by driving the circuit board 310, so that the shifted light rays converge to the center of the image sensor 320 again, thereby The purpose of improving the anti-shake effect of the camera module is achieved. Since the weight of the circuit board 310 and the image sensor 320 is small, the driving mechanism 400 can be set smaller, and the driving mechanism 400 requires less energy to work. Therefore, the camera module disclosed in the embodiment of the present application can solve the problems of large external dimensions and high power consumption existing in the anti-shake of the current camera module.

In an optional embodiment, the driving mechanism 400 can drive the circuit board 310 to rotate relative to the lens 200 . When the circuit board 310 rotates relative to the lens 200 , the distance between the center point of the lens 200 and the center point of the image sensor 320 needs to remain constant, and the way to drive the circuit board 310 to rotate is complicated, so the control is difficult. In another optional embodiment, the driving mechanism 400 can drive the circuit board 310 to move along the direction perpendicular to the optical axis of the lens 200. In this way, it is only necessary to keep the center point of the lens 200 to the vertical direction of the image sensor 320. The distance remains unchanged, and the driving circuit board 310 only needs to move, the movement mode is simple, and the control difficulty is less.

In a further optional embodiment, the number of the driving mechanism 400 is one. When the driving mechanism 400 drives the circuit board 310 to move in a direction perpendicular to the optical axis of the lens 200, the circuit board 310 has only one moving direction. In this way, It is difficult to ensure the accuracy of the position of the image sensor 320 after the movement. Therefore, the number of driving mechanisms 400 is at least two, including a first driving mechanism 410 and a second driving mechanism 420, the first driving mechanism 410 drives the circuit board 310 to move along the first direction, and the second driving mechanism 420 drives the circuit board 310 to move along the first direction. The second direction moves; wherein, both the first direction and the second direction are perpendicular to the optical axis of the lens 200 , and the first direction intersects the second direction. In this embodiment, there are multiple moving directions of the circuit board 310. When the driving mechanism 400 drives the circuit board 310 to move in a direction perpendicular to the optical axis of the lens 200, it can ensure that the displacement of the image sensor 320 is more accurate. The location is more accurate.

In another optional embodiment, the suspension assembly 300 further includes a rigid connector, one end of the rigid connector is slidably connected to the housing 100 , and the other end of the rigid connector is connected to the circuit board 310 . When the drive mechanism 400 drives the circuit board 310, since one end of the rigid connector is slidably connected to the housing 100, the circuit board 310 can move in a direction perpendicular to the optical axis of the lens 200. However, in this way, the housing 100 It is necessary to leave a large space for the movement of the rigid connection. Therefore, one end of the rigid link can be hinged to the casing 100 , and the rigid link can be stretched. However, in this way, the suspension assembly 300 may collide with the casing 100 due to the inertia of the movement. Therefore, the suspension assembly 300 may further include an elastic connector 330, one end of the elastic connector 330 is connected to the housing 100, the elastic connector 330 has elasticity, and when the elastic connector 330 is deformed, it can counteract at least part of the inertial force, thereby Collision between the circuit board 310 and the casing 100 can be avoided, and even if a collision occurs, the elastic connecting member 330 can also play a buffering role. The elastic connecting member 330 may be a component made of a copper alloy material, or may be a component made of other materials with elastic properties.

One end of the elastic connecting member 330 may be connected to the side wall of the housing 100 , but this structure will result in a force component of the force exerted by the elastic connecting member 330 on the circuit board 310 , which cannot be fully utilized. Based on this, optionally, the casing 100 has a first surface 101, the first surface 101 faces the image sensor 320, and the elastic connecting member 330 may be movably connected to the first surface 101, or may be fixedly connected to the first surface 101, the present application The embodiment does not limit this. The first surface 101 is located above the image sensor 320, so the elastic connecting member 330 can extend approximately along the optical axis of the lens 200, and the force exerted by the elastic connecting member 330 basically has no component force, so that the effect can be more fully utilized force, thereby improving the stability of the suspension assembly 300.

In a further embodiment, the elastic connector 330 can be a non-conductive member. In this case, the camera module needs to be provided with some wires for power supply connection. However, using wires in the internal space of the camera module is easy to make The circuit board 310 is entangled with the wires during movement. Therefore, the elastic connector 330 is a conductive member. At this time, the elastic connector 330 can also be electrically connected when the circuit board 310 is suspended, thereby reducing the internal wires of the camera module and avoiding contact between the circuit board 310 and the wires when moving. Winding occurs. In addition, the suspension assembly 300 may further include a focus motor 340 , the focus motor 340 is connected to the lens 200 , and the focus motor 340 is electrically connected to the circuit board 310 through the elastic connector 330 . The focus motor 340 may be a closed-loop drive motor, or an open-loop or mid-set drive motor. The focus motor 340 is electrically connected to the circuit board 310 through the conductive properties of the elastic connector 330 , so as to realize the focus function of the camera module, which is beneficial for the camera module to capture clearer images.

In a further optional embodiment, the focus motor 340 is bonded to the first surface 101 of the casing 100, and the focus motor 340 is connected to the elastic connector 330 through wires. However, in this way, since the focus motor 340 is connected to the first surface 101 has a limited connection area, and its own weight tends to detach the focus motor 340 from the first surface 101 of the housing 100 , and in addition, the connection between the wire and the elastic connecting member 330 is prone to entanglement. Therefore, the suspension assembly 300 may further include a bearing plate 350 and an electrical conductor 360, the bearing plate 350 is connected to the focus motor 340, and the bearing plate 350 is located between the focus motor 340 and the image sensor 320, the first end 361 of the electrical conductor 360 The second end 362 of the electrical conductor 360 extends to the side of the focus motor 340 facing away from the image sensor 320 , and the elastic connecting member 330 is connected and electrically conductive to the second end 362 of the electrical conductor 360 . In this embodiment, the carrier plate 350 has a supporting force for the focus motor 340 towards the first surface 101, therefore, the connection between the focus motor 340 and the first surface 101 can be made firmer and more reliable, and through the electrical conductor 360 Tangling can be avoided.

In one embodiment, the electrical conductor 360 may be a cylindrical strip. When the second end 362 of the electrical conductor 360 is connected to the side of the focus motor 340 facing away from the image sensor 320, it is easy to cause insufficient connection due to too small connection area. reliable. Therefore, the second end 362 of the electrical conductor 360 can be arranged in a sheet-like structure, which is bonded and connected to the side of the focus motor 340 facing away from the image sensor 320 , so that the connection area between the electrical conductor 360 and the focus motor 340 can be increased. , so that the connection between the electrical conductor 360 and the focus motor 340 is more reliable.

In another embodiment, the side of the focus motor 340 is provided with a first electrical conduction portion 341, and the side of the carrier plate 350 facing the focus motor 340 is provided with a second electrical conduction portion 351. In this case, the first electrical conduction portion 341 and The second electrical conduction portion 351 is in contact with and conducts electricity, however, this way of achieving electrical conduction only through contact is less reliable. Therefore, the focus motor 340 is provided with a first electrical conduction portion 341, the focus motor 340 has a bottom surface 342, the bottom surface 342 faces the image sensor 320, the first electrical conduction portion 341 is arranged on the bottom surface 342, the first electrical conduction portion 341 and the second electrical conduction portion 351 abuts against and conducts electricity. In this way, pressure is formed between the first electrical conduction portion 341 and the second electrical conduction portion 351 to conduct electrical conduction, and the first electrical conduction portion 341 and the second electrical conduction portion 351 abut more compactly, therefore, reliable Sex is better.

In one embodiment, the elastic connecting member 330 includes a first connecting plate 331, a spring and a second connecting plate 333, the first connecting plate 331 is connected to the second connecting plate 333 through a spring, the first connecting plate 331 is connected to the housing 100 The inner surface is bonded and connected, and the first connecting plate 331 is bonded and connected to the side of the focus motor 340 facing away from the image sensor 320 , and the second connecting plate 333 is bonded and connected to the side of the circuit board 310 facing away from the image sensor 320 . In this method, since the spring is generally a cylindrical structure, the space occupied by the spring is relatively large. Therefore, the elastic connecting member 330 may also include a bent section 332 through which the first connecting plate 331 is connected to the second connecting plate 333. In this way, the spring may be replaced by the bent section 332, and the bent section The volume of 332 can be made smaller, therefore, the space occupied by the bent section 332 is smaller. In a further embodiment, the shape of the bent section 332 is flat, and the space occupied by the bent section 332 of this shape is smaller.

In an optional embodiment, the bent section 332 includes at least two first strip portions 332a and at least two second strip portions 332b, and an acute angle may be formed between the first strip portions 332a and the second strip portions 332b , at this moment, the bending section 332 is a V-shaped structure, and this kind of bending section 332 has relatively high elasticity. When the bending section 332 is deformed, it cannot provide a large force. Therefore, in other embodiments, the first strip-shaped portion 332a extends along a direction perpendicular to the optical axis of the lens 200, the second strip-shaped portion 332b extends along the optical axis direction of the lens 200, and each first strip-shaped portion 332a extends along the direction of the optical axis of the lens 200. 200 are arranged in the direction of the optical axis, and each first strip-shaped portion 332a is located in the same plane, and the ends of adjacent first strip-shaped portions 332a are connected by the second strip-shaped portion 332b. In this embodiment, each first strip-shaped portion 332a is parallel to each other, and the angle between the first strip-shaped portion 332a and the second strip-shaped portion 332b is 90°, so the elasticity of the bending section 332 is more moderate.

The bracket 370 can be an injection-molded plastic part for carrying the filter 380 . The filter 380 can filter the received light so that the image sensor 320 can achieve a better image effect.

In one embodiment, the distance between every two adjacent first bar-shaped portions 332a may be equal, in other words, each first bar-shaped portion 332a may be arranged at equal intervals. In this embodiment, the bonding area between the first bar-shaped portion 332a provided corresponding to the circuit board 310 and the bracket 370 and the side walls of the circuit board 310 and the bracket 370 is relatively large, thereby causing a large impact on the movement of the circuit board 310. resistance. In order to solve this problem, the distance between two adjacent first bar-shaped portions 332a opposite to the circuit board 310 and the bracket 370 can be made larger than the distance between the remaining two adjacent first bar-shaped portions 332a. In this embodiment, the number of first bar-shaped parts 332a close to the circuit board 310 and the bracket 370 is relatively small, and the distribution is relatively sparse, so that the first bar-shaped parts 332a can be connected with the circuit board 310 suspended on the elastic connector 330 The bonding area with the side wall of the bracket 370 is smaller, so that the circuit board 310 moves more smoothly. Moreover, the structure of the bending section 332 in this embodiment is simpler.

The manufacturing material of the magnetic element 440 may be magnetic materials such as aluminum iron boron. The coil 430 can be fixed on the circuit board 310 by an adhesive material such as solder paste or conductive glue, so as to realize electrical conduction between the coil 430 and the circuit board 310 . After the coil 430 is energized, the magnetic field force generated by it interacts with the magnetic field force generated by the magnetic member 440, thereby realizing the movement of the circuit board 310.
