[0002] With the development of electronic devices, people have higher and higher requirements for electronic devices to take pictures. When a user holds an electronic device to take pictures, the user's holding of the electronic device will cause shaking, which will cause the image taken by the electronic device to be unstable due to the shaking.

[0003] In the related art, in order to reduce the impact of shaking on shooting, electronic devices usually use micro-pan-tilt anti-shake cameras, and set them in the electronic devices through independent packaging. However, when electronic devices use the micro-pan-tilt anti-shake camera independent packaging method, it is necessary to occupy the layout space of the circuit board in the electronic device (for example, the circuit board needs to have an avoidance hole), thereby compressing the layout area of ​​the circuit board, thereby limiting the layout of electronic devices.

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] The technical solutions disclosed in various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1 to 6The embodiment of the present invention discloses a circuit board device, which can be used to be set in electronic devices such as mobile phones, tablet computers, cameras, etc. The disclosed circuit board device includes a first circuit board 100 and a camera module 200. The first circuit board 100 can be used to lay out network wiring, electronic components, etc.

[0025] The first circuit board 100 is provided with a window hole 110 . The camera module 200 includes a camera 210 , a module bracket 220 and an anti-shake driving mechanism 230 . The camera 210 faces the window hole 110 , and the camera 210 can take pictures through the window hole 110 .

[0026] The module bracket 220 is the base for installing the camera 210. The camera 210 is movably arranged on the module bracket 220. The anti-shake driving mechanism 230 is connected between the camera 210 and the module bracket 220 to drive the camera 210 to perform anti-shake movement. The module bracket 220 includes a second circuit board. The second circuit board can be used to lay out network wiring, electronic components, etc., and can be electrically connected to the first circuit board 100 to achieve interaction.

[0027] The embodiment disclosed in the present application configures the module bracket 220 to include a structure of a second circuit board, so that the module bracket 220 can not only provide a base for installing the camera 210, but also play a role in installing other electronic components, thereby making up for the missing layout space caused by the opening of the window hole 110 in the first circuit board 100, so that more electronic components can be arranged.

[0028] In order to increase the occupied area of ​​the second circuit board, optionally, the module bracket 220 can be a second circuit board, that is, the module bracket 220 is entirely formed by the second circuit board. The second circuit board can be provided with a receiving space 221 and an opening 222 connected to the receiving space 221, the opening 222 can be opposite to the window hole 110, the camera 210 can be installed in the receiving space 221, and the camera 210 can shoot through the opening 222 and the window hole 110. The anti-shake drive mechanism 230 can be provided between the second circuit board and the camera 210 to drive the camera 210 to perform anti-shake movement in the receiving space 221. The second circuit board can be used to install various electronic devices, and an electronic network such as wiring can be provided inside.

[0029] By setting the entire module bracket 220 as the second circuit board, the area of ​​the second circuit board can undoubtedly be increased. It is possible to choose to wire or set electronic components on the outer side of the module bracket 220 or on the surface facing away from the first circuit board 100, which is conducive to providing a larger area for laying out electronic devices.

[0030] In order to achieve the installation between the first circuit board 100 and the second circuit board, the surface where the opening 222 of the accommodating space 221 is located is fixedly connected to the board surface of the first circuit board 100 facing the camera module 200 through a plurality of spaced welding points 300, and the gaps 400 between adjacent welding points 300 are connected to the window hole 110 to form a heat dissipation channel connecting the two side spaces of the first circuit board 100. The welding point 300 can be a solder paste welding point. The electronic devices on the second circuit board and the electronic devices on the first circuit board 100 can form electrical conduction and interaction with each other through the welding points.

[0031] By fixing the surface where the opening 222 of the accommodating space 221 is located and the board surface of the first circuit board 100 facing the camera module 200 through a plurality of spaced-apart welding points 300, not only the connection between the first circuit board 100 and the second circuit board can be achieved, but also the first circuit board 100 and the second circuit board can be electrically connected through the welding points 300. By setting gaps between adjacent welding points 300 and connecting with the window hole 110, a heat dissipation channel connecting the spaces on both sides of the first circuit board 100 can be formed, thereby improving the heat dissipation performance.

[0032] In some embodiments, after the camera module 200 is turned on, the anti-shake driving mechanism 230 starts to work, and the anti-shake driving mechanism 230 drives the camera 210 to do anti-shake movement. After the camera module is turned off, the anti-shake driving mechanism 230 may need to continue to work to drive the camera 210 to reset. Of course, in some cases, the anti-shake driving mechanism 230 may have stopped working, and its camera 210 may not be reset, that is, the camera 210 has not returned to the initial position, which is not conducive to the next shooting of the camera module 200. In order to enable the camera 210 to reset, optionally, the module bracket 220 can be provided with a receiving space 221 and an opening 222 connected to the receiving space, and the opening 222 can be arranged opposite to the window hole 110, and the electronic device can also include an elastic anti-shake bracket 500, and the elastic anti-shake bracket 500 has certain elastic properties. The elastic anti-shake bracket 500 can be arranged in the receiving space 221, and the camera 210 can be connected to the elastic anti-shake bracket 500, and the elastic anti-shake bracket 500 can be used to drive the camera 210 to perform a reset movement.

[0033] Specifically, when the camera 210 is in the initial position, the elastic anti-shake bracket 500 is in a state of no deformation. When the camera module 200 is working, the anti-shake drive mechanism 230 drives the camera 210 to perform anti-shake movement. The camera 210 can drive the elastic anti-shake bracket 500 to move so that the elastic anti-shake bracket 500 produces elastic deformation. After the camera module 200 stops working, the anti-shake drive mechanism 230 stops working. When the camera 210 is not in the initial position, the elastic anti-shake bracket 500 is in a deformed state. The camera 210 can move to the initial position under the force of the elastic anti-shake bracket 500 to restore the elastic deformation.

[0034] By further providing an elastic anti-shake bracket 500, not only can the camera 210 be installed, but it is also beneficial to reset the camera 210 after anti-shake movement, thereby facilitating the next use of the camera module.

[0035] Specifically, the anti-shake driving mechanism 230 may include a first magnetic driving mechanism 231, and the first magnetic driving mechanism 231 may include a plurality of first magnetic members 231a and a plurality of first magnetic members 231b. The plurality of first magnetic members 231a may be respectively arranged on a plurality of side surfaces of the camera 210, i.e., the side walls surrounding the optical axis of the camera 210. The plurality of first magnetic members 231b may be respectively arranged on a plurality of side walls of the accommodating space 221, and the plurality of side walls of the accommodating space 221 may also be the side walls surrounding the optical axis of the camera 210. The plurality of first magnetic members 231b are matched with the plurality of first magnetic members 231a in a one-to-one correspondence to drive the camera 210 to move in a plane perpendicular to the direction of its optical axis for anti-shake. Specifically, the first magnetic member 231a can be a first permanent magnet, and the first magnetic member 231b can be a first electromagnetic coil. When the first electromagnetic coil is used, the current magnitude and current direction of the first electromagnetic coil can be changed, and then cooperated with the first magnetic member 231a, so as to achieve the anti-shake movement of the camera 210 under the action of mutual attraction and repulsion. The first electromagnetic coil can be formed by wiring and etching during the production of the second circuit board. Of course, the first magnetic member 231a can be an electromagnetic coil, and the first magnetic member 231b can be a permanent magnet, and there is no specific limitation here.

[0036] By setting the first magnetic driving mechanism 231 to include multiple first magnetic components 231a and multiple first magnetic components 231b, the multiple first magnetic components 231a are respectively arranged on multiple side surfaces of the camera 210, and the multiple first magnetic components 231b are respectively arranged on multiple side walls of the accommodating space 221, so that the multiple first magnetic components 231b correspond one-to-one with the multiple first magnetic components 231a to drive the camera 210 to move and anti-shake in a plane perpendicular to its optical axis direction, thereby realizing movement and anti-shake of the camera 210 in a plane perpendicular to its optical axis direction.

[0037] In order to make the elastic anti-shake bracket 500 have better deformation performance, the elastic anti-shake bracket 500 may include a plurality of connecting strips 510 and a plurality of elastic rings 520 which are sequentially arranged from the outside to the inside and spaced apart. The first ends of the plurality of connecting strips 510 may protrude from the outermost elastic ring 520. The second ends of the plurality of connecting strips 510 sequentially pass from the outermost elastic ring 520 to the innermost elastic ring 520 and are connected to the outer edge of the innermost elastic ring 520. The first ends of the plurality of connecting strips 510 are all connected to the inner wall of the accommodating space 221. The plurality of connecting strips 510 are spaced apart along the circumference of the elastic ring 520. The plurality of elastic rings 520 may form a supporting surface, and the camera 210 is arranged on the supporting surface.

[0038] By adopting the closed annular structure of the elastic ring 520, the elastic ring 520 can be deformed in all directions, so that the deformation performance is better, and it is also beneficial to drive the reset of the camera 210. The elastic anti-shake bracket 500 can be formed simultaneously with the wiring etching step of the conductive layer in the process of manufacturing the second circuit board, without adding additional processes.

[0039] In order to achieve anti-shake of the camera 210 in more directions, the anti-shake drive mechanism 230 may also include a second magnetic drive mechanism 232, the accommodating space 221 may have a bottom wall opposite to the opening 222, the second magnetic drive mechanism 232 may include a plurality of second magnetic members 232a and a plurality of second magnetic members 232b, the plurality of second magnetic members 232b may be arranged on the bottom wall, the plurality of second magnetic members 232a may be arranged on the bottom surface of the camera 210, and the bottom surface of the camera 210 is the side facing the bottom wall. The plurality of second magnetic members 232a cooperate with the plurality of second magnetic members 232b to drive the camera 210 to rotate or move along its optical axis, and the elastic anti-shake bracket 500 may be arranged between the bottom surface and the bottom wall. Specifically, the second magnetic member 232a may be a second permanent magnet, and the second magnetic member 232b may be a second electromagnetic coil. In the case of using the second electromagnetic coil, the current size and current direction of the second electromagnetic coil can be changed, and then cooperated with the second magnetic member 232a, so as to achieve the anti-shake movement of the camera 210 under the action of mutual attraction and repulsion. The second electromagnetic coil can be formed by wiring and etching during the production of the second circuit board. Of course, the second magnetic member 232a can be an electromagnetic coil, and the second magnetic member 232b can be a permanent magnet, which is not specifically limited here.

[0040] Specifically, multiple second magnetic members 232a and multiple second magnetic members 232b can be symmetrically distributed on the orthographic projection of the bottom surface of the camera 210. When the camera 210 moves along the optical axis, the symmetrical multiple second magnetic members 232a can cooperate with the corresponding second magnetic members 232b to realize the movement of the camera 210 along the optical axis. When the camera 210 needs to rotate, the partially asymmetric second magnetic members 232a can cooperate with the corresponding second magnetic members 232b to tilt the camera 210 for rotation. Of course, the movement and rotation of the camera 210 along its optical axis can also be other cooperation modes, which will not be repeated here.

[0041] By cooperating with the plurality of second magnetic elements 232a and the plurality of second magnetic elements 232b, the camera 210 can be further rotated or moved along its optical axis, thereby achieving anti-shake of the camera 210 in more directions.

[0042] In order to better achieve anti-shake of the camera 210, the elastic anti-shake bracket 500 can be suspended on the bottom wall, so that the elastic anti-shake bracket 500 has a movement margin along the optical axis direction of the camera 210, so as to better prevent shake. Moreover, the camera 210 will generate heat when working. The elastic anti-shake bracket 500 being suspended in the air can make the camera 210 suspended in the air, which is beneficial to the dissipation of heat of the camera 210.

[0043] In order to make full use of the existing structure of the second circuit board, optionally, the second circuit board may include a metal layer, the metal layer may include a hollow area, and the hollow area may form the anti-shake driving mechanism 230. By forming the hollow area on the metal layer of the second circuit board, so that the hollow area serves as the anti-shake driving mechanism 230, the existing structure of the second circuit board can be fully utilized to form the anti-shake driving mechanism 230.

[0044] Specifically, the metal layer can be a copper layer. The copper layer not only has good ductility, so that the elastic anti-shake bracket 500 can better achieve elastic deformation, but also because the copper layer does not affect magnetism, it can further avoid driving interference with the driving of the second magnetic driving mechanism 232.

[0045] The present application also discloses an electronic device, and the disclosed electronic device includes the circuit board device disclosed in the above embodiment. By setting the circuit board device in the above embodiment in the electronic device, the second circuit board can make up for the layout space lost by the first circuit board 100 to avoid the installation of the camera module 200, so that the layout area of ​​the circuit board in the electronic device can be increased. And it can solve the problem that the layout area of ​​the circuit board of the electronic device is small due to the squeezing of the space of the electronic device by the independent packaging of the micro-pan-tilt anti-shake camera of the camera module. By including the second circuit board in the module bracket 220, the layout area of ​​the circuit board of the electronic device can be better increased. The electronic device can be a mobile terminal device such as a mobile phone, a tablet, a computer, a smart watch, and a smart glasses, and can also be suitable for other smart terminal devices such as vehicle-mounted devices.

[0046] The electronic device may also include a gyroscope, a gyroscope chip, an anti-shake processing chip, a power management chip, etc. After the camera function of the electronic device is turned on, the current parameters of the first electromagnetic coil and / or the second electromagnetic coil are controlled by the power management chip so that the first electromagnetic coil and / or the second electromagnetic coil generate a magnetic field, thereby acting on the first magnetic attraction component 231a and / or the second magnetic attraction component 232a connected to the camera 210 to drive the camera 210 to move, thereby achieving anti-shake of the camera 210.

[0047] The gyroscope chip can obtain the jitter of the camera 210 according to the gyroscope, and feed the jitter condition back to the anti-shake processing chip. The anti-shake processing chip can calculate the electrical magnitude and direction information of the first electromagnetic coil and the second electromagnetic coil required for spatial position correction of the camera 210 according to the jitter information. The anti-shake processing chip transmits the current information of each electromagnetic coil to the power management chip, and the power management chip controls the current magnitude and direction of the first electromagnetic coil and the second electromagnetic coil to achieve anti-shake of the camera 210.

[0048] The above embodiments of the present invention focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0049] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
