Description
Technical Field
[0001] This utility model relates to the field of camera device technology, and in particular to a camera module. Background Technology
[0002] In related technologies, a bracket needs to be installed on the outside of the camera module. Since the camera module has a flexible circuit board on its outside, and a connector is provided at one end of the flexible circuit board, in order to avoid interference between the flexible circuit board and the bracket, and to meet the requirements of the whole machine assembly, the flexible circuit board (Flexible Printed Circuit, or FPC for short) needs to be bent and attached to the bracket. However, the elastic force of the flexible circuit board after bending and fixing with glue will cause the flexible circuit board to separate from the bracket and lift up, making it difficult to meet the requirements of the whole machine assembly. Utility Model Content

[0028] The following is a reference appendix. Figure 1-6 This application describes a camera module 100 according to some embodiments.
[0029] like Figures 1-4As shown, the camera module 100 according to an embodiment of the present utility model includes: a camera assembly, a bracket 10, a flexible circuit board 20, and a limiting member 30.
[0030] It is understandable that the camera module 100 can be used in shooting devices such as cameras or smartphones. The camera module 100 includes, but is not limited to, vertical camera modules, horizontal camera modules, or telephoto periscope camera modules. In the implementation of the camera module 100 as a telephoto periscope camera module, a special optical design is adopted - the lens is arranged horizontally in the form of a "periscope" and combined with the refraction of light by a prism, so that light can travel a longer distance in a limited space, thereby achieving a higher magnification optical zoom effect.
[0031] The bracket 10 is used to install the camera assembly to realize the installation and fixation of the camera assembly. One end of the camera assembly is provided with a flexible circuit board 20, and a connector is provided on the flexible circuit board 20. The connector is used to connect to an external power source.
[0032] For example, in the implementation of camera module 100 as a telephoto periscope camera module, bracket 10 is used to fix the prism. The camera assembly and image sensor are both mounted on the bracket and positioned opposite the prism. Light enters the prism from the camera assembly, is reflected inside the prism, and then exits towards the image sensor. The camera assembly may include a motor and a lens. The lens is mounted on the motor, and the motor can be mounted on the bracket. One end of the flexible circuit board 20 is electrically connected to the motor, and the other end is provided with a connector to facilitate connection to an external power source. In this way, the power supply to or from the motor or other structures of the camera assembly can be controlled via the flexible circuit board.
[0033] The flexible circuit board 20 includes a body portion 21 and a bending portion 22. The body portion 21 is adapted to be electrically connected to the camera assembly. The bending portion 22 is electrically connected to the body portion 21 and adapted to fit against the outer peripheral wall of the bracket 10, so that the flexible circuit board 20 located on the outside of the bracket 10 is arranged more compactly with the bracket 10, and it is beneficial to reduce the space occupied by the flexible circuit board 20 located on the outside of the bracket 10. At the same time, it is beneficial to enable the camera module 100 to meet the overall assembly requirements.
[0034] In some feasible implementations, the bent portion 22 can be attached to the outer peripheral wall of the bracket 10 by using adhesive substances such as glue, adhesive or double-sided tape, so that the bent portion 22 can be stably attached to the outer peripheral wall of the bracket 10, thereby enhancing the connection stability between the bent portion 22 and the outer peripheral wall of the bracket 10.
[0035] The limiting member 30 is connected to the outer peripheral wall of the bracket 10 and at least partially abuts against the side of the bent portion 22 away from the bracket 10.
[0036] It is understandable that the main body 21 and the bending part 22 are an integral structure. The flexible circuit board 20 is partially bent to form the bending part 22. Since the flexible circuit board 20 itself has a certain elastic deformation capability, when the flexible circuit board 20 is partially bent to form the bending part 22, the bending part 22 will generate a spring force to restore deformation. If the bending part 22 is directly attached to the outer peripheral wall of the bracket 10, the bending part 22 will be lifted relative to the outer peripheral wall of the bracket 10 under the action of the spring force and then separate from the bracket 10. If adhesive substances such as glue, adhesive or double-sided tape are used to stick the bending part 22 to the outer peripheral wall of the bracket 10, there is a problem that the adhesion is not reliable and the adhesive substance is easy to fail.
[0037] To address this, this application includes a limiting element 30, such as... Figure 1 and Figure 2 As shown, at least a portion of the limiting member 30 abuts against the side of the bent portion 22 away from the bracket 10. In this way, the limiting member 30 can apply a force to the bent portion 22 in the direction close to the outer peripheral wall of the bracket 10, thereby enabling the flexible circuit board 20 to overcome the springback force generated after bending, thereby reducing the risk of the flexible circuit board 20 separating from the bracket 10 and lifting up, so as to prevent the bent portion 22 from separating from the outer peripheral wall of the bracket 10. In this way, the bent portion 22 can be stably attached to the outer peripheral wall of the bracket 10, and the camera module 100 meets the requirements of the whole machine assembly.
[0038] In some implementations, the connection method between the limiting member 30 and the outer peripheral wall of the bracket 10 includes, but is not limited to, welding, snap-fitting, plugging, bolting, or magnetic attraction, which can achieve the connection between the limiting member 30 and the outer peripheral wall of the bracket 10.
[0039] In some embodiments, the limiting member 30 is detachably connected to the outer peripheral wall of the bracket 10. This allows for flexible selection of the limiting member 30 according to the user's actual needs and reduces the difficulty of replacing the limiting member 30.
[0040] In some embodiments, such as Figures 1-3 As shown, the outer peripheral wall of the bracket 10 is provided with a limiting structure 40, and the limiting member 30 is inserted into the limiting structure 40. The limiting member 30 is disposed between the outer peripheral wall of the bracket 10 and the limiting structure 40.
[0041] It is understandable that the limiting component 30 and the limiting structure 40 are plugged together so that the limiting component 30 is indirectly connected to the outer peripheral wall of the bracket 10, thereby enhancing the connection stability between the limiting component 30 and the bracket 10. The plugging and connecting method is relatively simple and helps to reduce the installation cost. At the same time, it can meet the requirement of detachable connection between the limiting component 30 and the limiting structure 40, so that the limiting component 30 can be flexibly selected according to the user's actual needs, and the difficulty of replacing the limiting component 30 can be reduced.
[0042] In some embodiments, the limiting structure 40 is detachably connected to the outer peripheral wall of the bracket 10. This allows for flexible selection of the limiting structure 40 according to the user's actual needs and reduces the difficulty of replacing the limiting structure 40.
[0043] In some implementations, the connection method between the limiting structure 40 and the outer peripheral wall of the bracket 10 includes, but is not limited to, snap-fit, plug-in, bolt connection or magnetic attraction, which can achieve a detachable connection between the limiting structure 40 and the outer peripheral wall of the bracket 10.
[0044] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the limiting structure 40 is provided with a limiting groove 401, and the limiting member 30 is inserted into the limiting groove 401.
[0045] It is understandable that, such as Figure 1 and Figure 2 As shown, the limiting member 30 can be constructed as a plate-like structure, which makes the structure of the limiting member 30 relatively simple and reduces the difficulty of setting the limiting member 30. The limiting member 30 is inserted into the limiting groove 401 so that the limiting member 30 and the limiting structure 40 can be inserted and matched. The insertion and matching method is relatively simple and reduces the setting cost. At the same time, it can meet the setting of detachable connection between the limiting member 30 and the limiting structure 40, so as to flexibly select the limiting member 30 according to the actual use needs of the user, and also reduce the difficulty of replacing the limiting member 30.
[0046] In some embodiments, the limiting member 30 is bonded to the inner wall of the limiting groove 401.
[0047] It is understandable that adhesive substances such as glue (not shown in the figure), glue, or double-sided tape can be applied between the inner wall of the limiting groove 401 and the limiting member 30, so that the limiting member 30 can be bonded to the connecting structure while it is being inserted and engaged with the connecting structure. This can further enhance the connection stability between the limiting member 30 and the connecting structure. Moreover, the use of adhesive substances can reduce the shaking of the limiting member 30 in the limiting groove 401, thereby enhancing the stability of the engagement between the limiting member 30 and the limiting groove 401, and thus enhancing the limiting effect of the limiting member 30 on the bent part 22.
[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the extending direction of the limiting member 30 is perpendicular to the extending direction of the bent portion 22.
[0049] This makes it easier to reduce the difficulty of setting the limiting member 30, and facilitates the connection between the bent part 22 and the outer peripheral wall of the bracket 10, avoiding interference between the connection between the limiting member 30 and the bracket 10 and the bent part 22.
[0050] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the limiting structure 40 includes a first sub-plate 41 and a second sub-plate 42. The first sub-plate 41 is connected to the bracket 10. The second sub-plate 42 is bent and connected to the first sub-plate 41 and is spaced apart from the bracket 10. A limiting groove 401 is defined between the bracket 10, the first sub-plate 41 and the second sub-plate 42.
[0051] This allows for the setting of the limiting groove 401 by adding a first sub-plate 41 and a second sub-plate 42 without changing the original bracket 10. The setting method of the first sub-plate 41 and the second sub-plate 42 is relatively simple, which helps to reduce the difficulty of setting the limiting groove 401.
[0052] Meanwhile, the portion of the limiting member 30 extending into the limiting groove 401 is located between the outer peripheral wall of the bracket 10 and the second sub-plate 42. In this way, the second sub-plate 42 can play a certain limiting role for the limiting member 30, thereby preventing the limiting member 30 from separating from the connecting structure 40. At the same time, the first sub-plate 41 can serve as the bottom wall of the limiting groove 401 to abut against the limiting member 30, thereby further enhancing the structural stability of the limiting member 30.
[0053] In some embodiments, such as Figures 4-6 As shown, the limiting structure 40 further includes a third sub-plate 43, which is connected between the bracket 10 and the second sub-plate 42. A limiting groove 401 is defined between the third sub-plate 43, the first sub-plate 41, the second sub-plate 42 and the bracket 10. The first sub-plate 41 is adapted to abut against the limiting member 30 in the first direction X, and the third sub-plate 43 is adapted to abut against the limiting member 30 in the second direction Y. The first direction X and the second direction Y intersect.
[0054] In this way, the first sub-plate 41 can be used to limit the limiting member 30 in the first direction X, and the third sub-plate 43 can be used to limit the limiting member 30 in the second direction Y. Since the first direction X and the second direction Y intersect, the first sub-plate 41 and the third sub-plate 43 can limit the limiting member 30 in two different directions, thereby enhancing the structural stability of the limiting member 30.
[0055] For example Figure 1As shown, the first sub-plate 41 can serve as the bottom wall of the limiting groove 401. The first direction X can be a direction parallel to the insertion direction of the limiting member 30. In this way, after the limiting member 30 is inserted into the limiting groove 401, the first sub-plate 41 can abut against the bottom of the limiting member 30 in the first direction X, thereby limiting the limiting member 30 in the first direction X, thus enhancing the structural stability of the limiting member 30 and preventing the limiting member 30 from being inserted too far. The second sub-plate 42 can prevent the limiting member 30 from disengaging from the limiting groove 401 in a direction perpendicular to the bracket 10, while the third sub-plate 43 abuts against the limiting member 30 in the second direction Y, which can be a direction parallel to the second sub-plate 42. In this way, the limiting member 30 can be prevented from horizontally swaying relative to the second sub-plate 42, thereby further enhancing the structural stability of the limiting member 30.
[0056] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, there are two limiting structures 40, which are located on both sides of the bent portion 22. The two ends of the limiting member 30 are respectively inserted into the two limiting structures 40.
[0057] Therefore, by setting two limiting structures 40, both ends of the limiting member 30 can be inserted into the corresponding limiting structure 40. This makes it easy to fix both ends of the limiting member 30 using the two limiting structures 40, thereby enhancing the connection stability between the limiting member 30 and the bracket 10, and thus improving the limiting effect of the limiting member 30 on the bent part 22.
[0058] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the distance between the two limiting structures 40 is greater than the width of the bent portion 22.
[0059] This allows the bent portion 22 to pass through the space between the two limiting structures 40 when it is in contact with the outer peripheral wall of the bracket 10, thereby avoiding interference between the bent portion 22 and the limiting structure 40 and reducing the difficulty of fitting the bent portion 22 with the outer peripheral wall of the bracket 10.
[0060] In some embodiments, such as Figure 2 As shown, the orthographic projection of the limiting member 30 on the bracket 10 falls on the middle area of the bent portion 22. This allows the limiting member 30 to press against the middle area of the bent portion 22, thereby making the force on the entire bent portion 22 more balanced, thus ensuring the force stability of the bent portion 22, and thus ensuring the fit between the bent portion 22 and the outer peripheral wall of the bracket 10.
[0061] Therefore, in the camera module 100 of this utility model embodiment, the limiting member 30 can abut against the side of the bent portion 22 away from the bracket 10, so that the limiting member 30 can make the flexible circuit board 20 overcome the springback force generated after bending, thereby reducing the risk of the flexible circuit board 20 separating and lifting from the bracket 10, so as to prevent the bent portion 22 from separating from the outer peripheral wall of the bracket 10, ensuring that the bent portion 22 can be stably attached to the outer peripheral wall of the bracket 10, and the camera module 100 meets the assembly requirements of the whole machine.
