[0013] 1 to 6, a camera assembly according to an embodiment of the present application includes a first circuit board 10, a flexible circuit board 20, a base 30, a plurality of first elastic members 40, a first coil 11, and a photosensitive chip 12, wherein fixed ends 41 of the plurality of first elastic members 40 are fixedly attached to the base 30, and free ends 42 of the plurality of first elastic members 40 are suspended, the first circuit board 10 is attached to a suspension frame formed by the plurality of first elastic members 40, and the first coil 11 and the photosensitive chip 12 are provided on the first circuit board 10, one end of the flexible circuit board 20 is fixedly connected to the first circuit board 10, and the other end of the flexible circuit board 20 is fixedly connected to the base 30.

A circuit is installed inside the first circuit board 10, and the photosensitive chip 12 on the first circuit board 10 and the first coil 11 are electrically connected through the internal circuit.

[0015] As described above, one end of the flexible circuit board 20 is fixedly connected to the first circuit board 10, and the other end of the flexible circuit board 20 is fixedly connected to the base 30. In this way, the flexible circuit board 20 can be electrically connected to elements other than the camera assembly via the end connected to the base 30, and the flexible circuit board 20 can be electrically connected to the first circuit board 10 via the end connected to the first circuit board 10.

[0016] The base 30 may be made of a liquid crystal polymer (LCP) material or other materials, and is not specifically limited herein.

[0017] The first elastic member 40 may be a spring, and may be formed by etching and bending a common alloy material, such as iron or copper. A fixed end 41 of the first elastic member 40 is fixedly attached to the base 30. Alternatively, the fixed end 41 of the first elastic member 40 may be fixed to the base 30 by adhesive, and a free end 42 of the first elastic member 40 is suspended to form a suspension frame, on which the first circuit board 10 is placed, suspending the entire first circuit board 10. In this way, the suspended first circuit board 10 can move freely without being restricted by external forces.

[0018] Optionally, the first elastic member 40 is perpendicular to the base 30. In this way, the internal space occupied by the first elastic member 40 can be reduced, and the laminate thickness of the entire electronic device can be reduced.

[0019] The first coil 11 is also called an anti-shake coil, and may be fixed to the first circuit board 10 by welding.

[0020] The photosensitive chip 12 may be mounted on the first circuit board 10 by a flip-chip mounting process, and the photosensitive chip 12 is used to convert the received optical signal into an electrical signal to form a captured image.

[0021] It should be understood that the camera assembly in this embodiment is further provided with a permanent magnet 61, which generates a magnetic field, and all components in the camera assembly are in this magnetic field, where the first coil 11 is affected by the magnetic field generated by the permanent magnet 61 after being energized, generating an ampere force that drives the first circuit board 10.

[0022] The application principle of this embodiment is as follows: After the first coil 11 is energized, the first coil 11 and the permanent magnet 61 cooperate to generate an ampere force, which drives the first circuit board 10 to move, thereby moving the photosensitive chip 12 and preventing camera shake caused by the chip.

[0023] In the embodiment of the present application, the free ends 42 of the plurality of first elastic members 40 are suspended, and the first circuit board 10 on which the photosensitive chip 12 is mounted is attached to a suspension frame formed by the plurality of first elastic members 40, thereby realizing suspension of the first circuit board 10 without using metal suspension wires to suspend the first circuit board 10. Also, in the embodiment of the present application, one end of the flexible circuit board is fixedly connected to the first circuit board 10, and the other end of the flexible circuit board is fixedly connected to the base 30, eliminating the need to bend the flexible circuit board, and this method reduces the difficulty of assembling the camera assembly.

[0024] Optionally, the number of the first elastic members 40 is four, the first circuit board 10 is a rectangular circuit board, and the first elastic members 40 are located at the four vertices of the first circuit board 10.

[0025] 4 is a front view of a first circuit board according to an embodiment of the present application. As shown in FIG. 4, the first circuit board 10 is a rectangular circuit board and includes four first elastic members 40. The four first elastic members 40 are located at the four vertex corners of the rectangular circuit board. The first elastic members 40 located at the four vertex corners of the rectangular circuit board can move along the diagonal lines of the rectangular circuit board. In this way, the first elastic members 40 located at the four vertex corners of the first circuit board 10 can provide maximum support for the first circuit board 10 to prevent the first circuit board 10 from falling off the suspension frame during movement.

[0026] It should be understood that the number of the first elastic members 40 may be two, and the two first elastic members 40 are located on opposite sides of the first circuit board 10 .

[0027] Optionally, the free end 42 of the first elastic member 40 is located at the bottom of the first circuit board 10, and the free end 42 of the first elastic member 40 is fixedly connected to the first circuit board 10.

[0028] 5 is a structural schematic diagram of a first elastic member according to an embodiment of the present application. As shown in FIG. 5, the first elastic member 40 includes a fixed end 41 and a free end 42. Here, the free end 42 of the first elastic member 40 is located at the bottom of the first circuit board 10 and can be fixedly connected to the bottom of the first circuit board 10. In this way, the first elastic member 40 can more stably support the first circuit board 10.

[0029] When the number of first elastic members 40 is four, the free ends 42 of the first elastic members 40 may be placed on the opposite side of the first circuit board 10, so that the first elastic members 40 can more stably support the first circuit board 10.

[0030] Optionally, the first elastic member 40 includes a first connecting portion 43 and a second connecting portion 44, the fixed end 41 is located at the first connecting portion 43, and the free end 42 is located at the second connecting portion 44, the first connecting portion 43 is located at a first side of the first circuit board 10, and the second connecting portion 44 is located at a second side of the first circuit board 10, and the first side and the second side are adjacent sides of the first circuit board 10.

[0031] Continuing to refer to FIG. 5 , the first elastic member 40 includes a first connecting portion 43 and a second connecting portion 44. Here, the fixed end 41 is attached to the first connecting portion 43, and the free end 42 is attached to the second connecting portion 44. When the first circuit board 10 is a rectangular circuit board, the first connecting portion 43 may be located on a first side of the first circuit board 10, and the second connecting portion 44 may be located on a second side of the first circuit board 10, where the first side and the second side are adjacent sides of the first circuit board 10. In this way, the shape of the suspension frame formed by the plurality of first elastic members 40 is rectangular. In other words, the shape of the suspension frame is the same as the shape of the first circuit board 10, and the shape of the suspension frame can restrict the movement direction of the first circuit board 10 during movement, preventing the first circuit board 10 from falling off the suspension frame during movement.

[0032] Optionally, the first connection portion 43 is attached to a first side of the first circuit board 10, and the second connection portion 44 is attached to a second side of the first circuit board 10, and the first connection portion 43 and the second connection portion 44 are perpendicular to each other.

[0033] In this embodiment, the first connecting portion 43 of the first elastic member 40 is attached to a first side of the first circuit board 10, and the second connecting portion 44 is attached to a second side of the first circuit board 10. When the first circuit board 10 is a rectangular circuit board, the first connecting portion 43 and the second connecting portion 44 are perpendicular to each other. In this way, when the first circuit board 10 is attached to the suspension frame, the multiple first elastic members 40 sandwich the first circuit board 10, clamping and fixing the first circuit board 10 to the suspension frame.

[0034] Alternatively, the number of the flexible circuit boards 20 is two, and the flexible circuit boards 20 are partially connected to the two first connection portions 43 located on the same side of the first circuit board 10.

[0035] In this embodiment, when the number of first elastic members 40 is four, the number of flexible circuit boards 20 may be set to two. One flexible circuit board 20 may be connected to two first elastic members 40 located on opposite sides of the first circuit board 10. Specifically, one end of the flexible circuit board 20 may be connected to the first connecting portion 43 of one first elastic member 40, and the other end of the flexible circuit board 20 may be connected to the first connecting portion 43 of another first elastic member 40, and a portion of the flexible circuit board 20 may be formed in an arch shape, where the two first elastic members 40 are disposed opposite each other.

[0036] In this way, during the process of using the chip to prevent camera shake, the first circuit board 10 moves, and the first elastic member 40 moves following the first circuit board 10. One flexible circuit board 20 is supported by two oppositely installed first elastic members 40, and the flexible circuit board 20 also moves following the first elastic member 40, further preventing the flexible circuit board 20 from breaking during the process of using the chip to prevent camera shake. There is no need to form the flexible circuit board 20 into a bent structure through a bending process, which reduces the difficulty of assembling the camera assembly.

[0037] Optionally, the flexible circuit board 20 is designed as a single layer circuit board to reduce the resistance force that occurs when the flexible circuit board 20 moves.

[0038] In this embodiment, the flexible circuit board 20 is mounted on the first elastic member 40, and thereby the flexible circuit board 20 moves in accordance with the first elastic member 40. The flexible circuit board 20 is installed as a single-layer circuit board, and the internal space of the electronic device occupied by the flexible circuit board 20 is reduced, thereby making it possible to reduce the overall laminate thickness of the device.

[0039] Optionally, the length of the flexible circuit board 20 is made longer than the length of the two fixed ends 41 on the same side of the first circuit board 10, thereby increasing the length of the flexible circuit board 20.

[0040] Optionally, a protrusion 31 is provided on the base 30 , and the protrusion 31 is partially adhered to the flexible circuit board 20 .

[0041] 6 is a schematic diagram of the structure of a base according to an embodiment of the present application. In this embodiment, a protrusion 31 is provided on the base 30, and this protrusion 31 is a slope, and a portion of the flexible circuit board 20 is attached to the protrusion 31 of the base 30. Here, by attaching one surface of the flexible circuit board 20 to the protrusion 31 of the base 30, it is possible to prevent the flexible circuit board 20 from bending during movement.

[0043] In this embodiment, the case 50, the fixture 60, and the movable member 70 may be made of a liquid crystal polymer material. In this embodiment, one end of the lens 100 is bonded to the movable member 70, and the movable member 70 can move within the fixture 60, thereby moving the lens 100 and realizing the focusing function of the lens 100.

The second elastic member 80, the third elastic member 90, the second coil 71 and the permanent magnet 61 are all located in the first accommodating cavity. The fixing member 60 and the moving member 70 surround and form a second accommodating cavity and a third accommodating cavity on opposite sides of the moving member 70. The second elastic member 80 , is located in the second accommodating cavity, and the second elastic member 80 is perpendicular to the movable member 70, the third elastic member 90 is located in the third accommodating cavity, and the third elastic member 90 is perpendicular to the movable member 70, the second coil 71 is located in the first groove of the movable member 70, and the permanent magnet 61 is located in the second groove of the fixing member 60, and the permanent magnet 61 is installed opposite the second coil 71.

[0045] 1, the camera assembly further includes a filter 13. The filter 13 may be adhered to the first circuit board 10 to achieve a fixed connection between the filter 13 and the first circuit board 10, or the filter 13 may be fixedly connected to the first circuit board 10 in other ways, which are not specifically limited herein.

[0046] It should be understood that the filter 13 is used to filter out certain light rays to avoid image distortion, and optionally, the filter 13 may be an infrared filter 13 for filtering infrared light.

[0047] It should be understood that the filter 13 is disposed opposite the photosensitive chip 12, and the distance between the filter 13 and the lens 100 is smaller than the distance between the photosensitive chip 12 and the lens 100. That is, the filter 13 receives the light beam transmitted from the lens 100, filters out the light beam of a specific wavelength, and transmits the filtered light beam to the photosensitive chip 12.

[0048] In this embodiment, the second elastic member 80 and the third elastic member 90 may be springs, and the permanent magnet 61 may be a magnet. The second coil 71 is also called a focusing coil.

[0049] In this embodiment, when the second coil 71 is energized, an electromagnetic effect occurs between the second coil 71 and the permanent magnet 61, generating an Ampere force that drives the movable member 70 to move.
