Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.
For convenience of understanding the camera module provided in the embodiments of the present application, an application scenario of the camera module is first described, and the camera module is applied to a mobile terminal, such as a mobile phone, a notebook computer, a tablet computer, and other common mobile terminals.
Referring to fig. 1 to 4, the mobile terminal includes a mobile terminal body 100 and a camera module 10, wherein the camera module 10 is of a flip type. When the mobile terminal is used, the camera module 10 rotates to a certain position, and the rear part of the camera module is exposed outside the mobile terminal body 100 and can take a picture and take a picture. When not in use, the camera module 10 is accommodated in an accommodating space formed in the mobile terminal body 100.
Specifically, the turning of the camera module 10 can be realized by a driving device, which can be a driving motor, or a device formed by combining a driving motor and a reducer, or other different common driving devices. The present application is not limited thereto.
Because the flexible circuit board in the module of making a video recording 10 can be driven in the upset of the module of making a video recording 10 and move, this design that just needs the flexible circuit board reserves certain redundant quantity, and the redundant quantity of flexible circuit board can occupy great space area, consequently, how to improve the setting mode of flexible circuit board, becomes the problem that needs to solve.
It should be noted that, in the embodiment of the present application, the number of the cameras 12 is not limited, and may be one, two, or three, but when the number of the cameras 12 is more than two, the scheme of the present application has a better effect of saving space. Therefore, the following description will be made by taking two cameras as an example.
When two cameras 12 are used, the cameras 12 with the same specification can be selected, and the cameras 12 with different specifications can also be selected, for example, one camera 12 is a wide-angle camera 12, and the other camera 12 is a narrow-angle camera 12; alternatively, the pixels of the two cameras 12 are the same or different.
With continued reference to fig. 3 and 4, two cameras 12 are shown, and each camera 12 corresponds to a flexible circuit board 14, the flexible circuit board 14 having a length and a width. Each flexible circuit board 14 includes two parts, wherein the lead-out portion 141 extends along the axis (shown by the dotted line in the figure) and is connected to the spiral portion 142, and the spiral portion 142 extends outward in a spiral shape around the axis and is connected to the corresponding camera 12.
For convenience of description, with reference to the direction of the paper, the left camera is referred to as a first camera, the right camera is referred to as a second camera, the first camera and the second camera rotate relative to respective axes, and the respective axes are overlapped in the drawing as an example. The flexible circuit board 14 connected with the first camera is a first flexible circuit board, and the flexible circuit board 14 connected with the second camera is a second flexible circuit board.
The lead-out part 141 of the first flexible circuit board and the lead-out part 141 of the second flexible circuit board both pass through the spiral part 142 of the first flexible circuit board; however, only the lead-out portion 141 of the second flexible circuit board penetrates into the spiral portion 142 of the second flexible circuit board, and the lead-out portion 141 of the first flexible circuit board does not penetrate into the spiral portion 142 of the second flexible circuit board. That is, after passing through the spiral part 142 of the first flexible circuit board, the second flexible circuit board is substantially independent from the first flexible circuit board, thereby making the routing manner simpler.
In addition, the optical signal received by the camera 12 is converted into an electrical signal and then transmitted to a corresponding processing circuit of the mobile terminal through the flexible circuit board 14. Therefore, the end of the lead-out portion 141 of the flexible circuit board 14 not connected to the spiral portion 142 is connected to a connector (not shown) or other plug or jack that may be capable of being connected to the processing circuit.
Alternatively, a portion of the lead-out portion 141 distant from the spiral portion 142 is provided with a bent structure, which is disposed along the housing of the mobile terminal and is connected with the connector.
Referring now to fig. 4, in the axial position, a rotating shaft 13 is provided. The shaft rotates the camera 12 about an axis (shown by a dotted line).
Optionally, the rotating shaft 13 is fixedly connected with a housing of the mobile terminal, the housing 11 of the camera 12 is rotatably connected with the rotating shaft 13, and the camera 12 rotates relative to the rotating shaft 13. Alternatively, the rotation shaft 13 is fixedly connected to the housing 11, and the rotation shaft 13 is rotatably connected to the housing of the mobile terminal, so that the camera 12 can rotate relative to the rotation shaft 13.
The lead-out portion 141 of the flexible circuit board 14 may be attached to the surface of the rotating shaft 13 and extend along the length direction of the rotating shaft 13, or the lead-out portion 141 is disposed in the rotating shaft 13, so as to prevent the housing 11 from touching the lead-out portion 141 when rotating, thereby improving the safety of the lead-out portion 141.
Specifically, when the lead-out portion 141 is disposed in the rotating shaft 13, it can be implemented in different manners, for example, in one embodiment, the rotating shaft 13 is provided with a groove which is disposed along the length direction of the rotating shaft 13, the lead-out portion 141 of the flexible circuit board 14 is disposed in the groove, and when the number of the flexible circuit boards 14 is two or more, a part of the lead-out portion 141 is stacked in the groove. When the groove is specifically arranged, the width of the groove is slightly larger than the thickness of the stacked lead-out portions 141 to ensure that the lead-out portions 141 can be stably located in the groove, the groove extends to the end of the rotating shaft 13 and forms an opening at the end of the rotating shaft 13, and the lead-out portions 141 extend out of the opening and are connected with the bending structure.
Optionally, the rotating shaft may also adopt a split structure. Referring to fig. 3 to 5, the shaft 13 includes two parts: the first half cylinder 131 and the second half cylinder 132 are symmetrically disposed, and horizontal planes of the two half cylinders are two adjacent surfaces. When installed, a gap is provided between the two horizontal surfaces of the first half cylinder 131 and the second half cylinder 132, and the gap is a gap for accommodating the lead-out portion 141. When the lead-out portion 141 is provided in the rotation shaft 13, the lead-out portion 141 is laid in a gap between the two semi-cylindrical bodies, and the width of the gap is slightly larger than the thickness of the laid lead-out portion 141 after lamination.
When the first half cylinder 131 and the second half cylinder 132 are combined to form the rotating shaft 13, in order to improve the strength of the whole rotating shaft 13 and reduce the bending risk of the rotating shaft 13, the reinforcing member 133 is provided, the reinforcing member 133 is used for connecting the first half cylinder 131 and the second half cylinder 132, and when the reinforcing member 133 is specifically provided, the number of the reinforcing members 133 may be one or more, and the reinforcing member is provided at the middle part of the rotating shaft 13 so as to improve the strength of the whole rotating shaft 13. When a plurality of reinforcing members 133 are used, the plurality of reinforcing members 133 are spaced along the length direction of the rotating shaft 13, and in a specific embodiment, when the number of the cameras 12 and the number of the reinforcing members 133 are both multiple, the cameras 12 and the reinforcing members 133 are alternately arranged, that is, one reinforcing member 133 is disposed between two cameras 12.
The shape of the reinforcing member 133 can be different, as shown in fig. 5, the reinforcing member 133 is a C-shaped reinforcing member 133, and one end of the reinforcing member 133 is fixedly connected to the first half cylinder 131, and the other end is fixedly connected to the second half cylinder 132, and when the connection is specifically implemented, a welding or bonding manner can be adopted, and common connecting members such as bolts and screws can also be adopted for connection. The number of the reinforcing members 133 is not limited to the C-shape shown in fig. 5, and other shapes such as U-shape or other shapes may be adopted. In addition, the reinforcing member 133 is not limited to the outer surface connecting the two half cylinders, and the reinforcing member 133 may be provided in the gap between the two half cylinders, but in this case, the provision of the reinforcing member 133 should be avoided from affecting the provision of the lead portion 141.
When the strength of the rotating shaft 13 is enhanced, in addition to the reinforcing member 133, the rotating shaft 13 further includes a connecting portion 134, and one end of the first semi-cylinder 131 and one end of the second semi-cylinder are both fixedly connected to the connecting portion 134, and when the rotating shaft is specifically and fixedly connected, different manners such as welding and bonding can be adopted, or the rotating shaft can be fixedly connected by using connecting members such as bolts, screws, rivets, etc. The connecting portion 134 is provided to enhance the strength of the rotation shaft 13, and when the rotation shaft 13 is fixedly connected to the housing of the mobile terminal, the connection portion 134 is fixedly connected to the housing. In addition, a bent portion is disposed at an end of the rotating shaft 13 away from the connecting portion 134, and the bent portion is used for fixedly connecting the other end of the rotating shaft 13 with the housing of the mobile terminal. The bent portion is fixedly connected to the first half cylinder 131 and the second half cylinder 132, so that the strength of the rotating shaft 13 can be enhanced.
As an alternative, the connection portion 134 may be integrated with the first half cylinder 131 and the second half cylinder 132, and in this case, it can be seen that a gap is provided at one end of the rotating shaft 13 of one cylinder, and the gap extends along the length direction of the rotating shaft 13 to form a space for accommodating the lead-out portion 141.
It should be understood that the above list is only a few specific structures that can realize the arrangement of the lead-out portion 141 in the rotating shaft 13, and the rotating shaft 13 provided in the present application may adopt other structures.
With continued reference to fig. 4, the camera module includes a housing 11. The shell 11 wraps the camera 12, and a plurality of accommodating cavities are formed in the shell 11 for accommodating the camera 12 and the flexible circuit board 14. Wherein, first chamber 111 that holds is used for holding camera 12, and optionally, camera 12 is through the mode of bonding and first chamber 111 fixed connection that holds, perhaps, adopts the welding, adopts the connecting piece (such as bolt, screw or rivet) and first chamber 111 fixed connection that holds.
The housing 11 further includes a second accommodating cavity 112, a portion of the flexible circuit board 14 is located in the second accommodating cavity 112, and the first accommodating cavity 111 and the second accommodating cavity 112 in the second accommodating cavity 112 are communicated, so that the flexible circuit board 14 can be inserted into the first accommodating cavity 111 and connected with the camera 12. When the flexible circuit board 14 is disposed, in order to improve the connection strength between the camera 12 and the flexible circuit board 14, one end of the flexible circuit board 14 inserted into the first accommodating cavity 111 is fixedly connected to the housing 11, for example, an adhesive is used for bonding and fixing, so as to ensure the stability of the flexible circuit board 14 and the camera 12 relative to the housing 11. When the flexible circuit board 14 is pulled, the resistance is improved through the adhesive, so that the connection between the camera 12 and the flexible circuit board 14 is prevented from being directly pulled, and the reliability of the camera module 10 is improved.
It should be understood that, in the structure shown in fig. 4, one first accommodating cavity 111 is shown to accommodate the cameras 12, but in the housing 11 provided in the embodiment of the present application, the number of the first accommodating cavities 111 may correspond to the number of the cameras 12, for example, the first cameras and the second cameras are arranged in the respective first accommodating cavities 111. Similarly, when the second accommodating cavity 112 is provided, the second accommodating cavity 112 is also provided in a manner similar to the first accommodating cavity 111, that is, the second accommodating cavity 112 may be provided in a one-to-one correspondence manner with the flexible circuit boards 14, or one relatively large second accommodating cavity 112 may accommodate all the flexible circuit boards 14.
In addition, the shell can adopt an integral structure or a split structure. When the split structure is adopted, the housing 11 includes two parts, namely a first housing 11 and a second housing 11, wherein the first housing 11 and the second housing 11 are detachably connected, for example, detachably connected through a connecting member (a bolt, a screw or a rivet), or detachably connected by a snap. When specifically setting up first shell 11 and second shell 11, first shell 11 and second shell 11 adopt symmetrical structural style to set up, wherein, have set up first recess on the first shell 11, the second shell 11 is gone up and is correspondingly set up the second recess, and when first shell 11 and second shell 11 fixed connection, first recess and second recess are to the box-shaped first chamber 111 that holds. Similarly, when the second housing cavity 112 is formed, the first housing 11 is provided with a third recess, the second housing 11 is provided with a fourth recess, and when the first housing 11 and the second housing 11 are aligned, the third recess and the fourth recess form the second housing cavity 112. Similarly, the first housing 11 and the second housing 11 are provided with grooves corresponding to the rotating shaft 13, and when the first housing 11 and the second housing 11 are fixedly connected, a through hole for accommodating the rotating shaft 13 is formed. And when adopting split type, can fix camera 12 on first shell 11 or second shell 11, later first shell 11 with second shell 11 to box fixed connection together, made things convenient for fixed camera 12. In addition to the above-mentioned split body, the housing 11 may also be integrated, and in this case, the housing 11 may be wrapped around the camera 12 by injection molding or other methods after the camera 12 and the flexible circuit board 14 are directly connected.
The configuration shown in fig. 4 is only a configuration in which one housing 11 accommodates all the cameras 12, but the configuration of the housing 11 in the camera module 10 according to the present invention is not limited to the correspondence relationship shown in fig. 4, and may be a configuration in which one housing 11 accommodates one camera 12. If it is necessary that a plurality of cameras 12 rotate asynchronously, one camera 12 may be used to correspond to one housing 11, and at this time, different rotation modes of the cameras 12 may be implemented by rotating different housings 11. In addition, when a plurality of cameras 12 need to move synchronously, one shell 11 can be adopted to accommodate all the cameras 12; it is also possible to use one housing 11 to accommodate one camera 12, but the connection between adjacent housings 11 ensures synchronous rotation.
