Description

TECHNICAL FIELD

[0001] The utility model relates to mobile phone camera module technique field, concretely relates to a mobile phone front camera module with automatic telescopic function. BACKGROUND

[0002] At present, camera has become an indispensable function of electronic equipment, and is more and more used in daily life, and along with the user's increasing demand for camera quality, camera module adopts focusing motor to drive the whole lens to move along the optical axis, thereby realizing the function of automatic focusing, and then the user can shoot clearer image. However, in order to meet the user's requirement for camera quality, the distance required by the lens to move is also longer and longer, which requires a larger space for the focusing motor to stretch out and retract. Therefore, the above problems lead to the large overall size of the existing camera module.

[0003] Through retrieval, the patent application number CN202210570186.9 discloses a camera module and electronic equipment, although the device realizes the telescopic function of the lens by driving the optical lens to stretch out and retract along the optical axis when in use. However, the device lacks sufficient positioning and stability protection for the camera module inside the mobile phone when in use. The positioning structure may not effectively prevent the module from shifting during use, affecting the shooting effect. Moreover, there is no mention of the optimization design for the connection between the module and the PCB, which lacks in connection strength and prevention of relative displacement caused by external force. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a mobile phone front camera module with automatic telescopic function, which solves the problems raised in the background art.

[0005] The technical problems solved by the utility model are as follows:

[0006] A mobile phone front camera module with automatic telescopic function, comprising a PCB, a lens is installed on the PCB through a lifting assembly;

[0007] Both sides of the PCB are provided with connecting pieces, the connecting pieces are located at the fixing holes of the PCB, the connecting pieces are provided with fixing plates, and the connecting pieces are connected and fixed with the PCB through the fixing plates;

[0008] The connecting pieces are provided with bottom plates, the bottom plates are provided with positioning lugs, and the connecting pieces are positioned by being clamped with the fixing holes of the PCB through the positioning lugs of the bottom plates.

[0009] On the basis of the above technical scheme, the utility model can also be improved as follows.

[0010] Further, an upper plate is arranged above the connecting piece, and a through hole is formed in the upper plate, and an adhesive is filled in the through hole.

[0011] The beneficial effects of the above further scheme are:

[0012] The arrangement of the upper plate provides a structural basis for enhancing the connection, and after the adhesive is filled in the through hole, the adhesive is tightly combined with the material around the fixing hole of the PCB during the curing process, forming a double effect of mechanical occlusion and chemical adhesion. This greatly enhances the connection strength between the connecting piece and the PCB, effectively prevents relative displacement between the two due to external factors such as vibration and shaking in daily use, ensures the stability of the camera module inside the mobile phone, and ensures its reliable operation. At the same time, the adhesive filled in the through hole plays a certain protective role for the edge of the fixing hole of the PCB, reduces the damage of the fixing hole caused by friction, stress concentration and other factors, and prolongs the service life of the entire module.

[0013] Further, the PCB is fixed by the connecting piece and the fixing hole of the main PCB.

[0014] The beneficial effects of the above further scheme are:

[0015] Compared with other connection methods, the clamping and fixing method is more convenient and fast to install. In the mobile phone production and assembly link, workers only need to align the camera module PCB with the fixing hole of the main PCB, and press or clamp gently to complete the connection, which greatly improves the production efficiency. Moreover, the clamping structure has a certain elasticity and toughness, and can absorb and buffer the vibration and impact force generated during the use of the mobile phone to a certain extent, avoid excessive external force from being transmitted to the camera module due to rigid connection, and protect the precise electronic elements inside the module from being damaged. In addition, the clamping and fixing is convenient for disassembling, repairing or replacing the camera module in the later stage, which reduces the maintenance cost and difficulty.

[0016] Further, the inner diameter of the through hole is greater than the inner diameter of the fixing hole of the PCB.

[0017] The beneficial effects of the above further scheme are:

[0018] The through hole with a larger inner diameter provides sufficient space for the filling of the adhesive, can accommodate more adhesive, and enables the adhesive to better wrap and penetrate around the fixing hole of the PCB during the filling process, thereby enhancing the firmness of the connection. Meanwhile, the size difference allows for a certain positional error compensation during the installation process. When the connecting piece is installed with the PCB, even if there is a slight deviation in positioning, the adhesive can still be smoothly filled and effectively function due to the larger inner diameter of the through hole, thereby improving the fault tolerance and compatibility of the installation and ensuring that the PCB and the connecting piece produced in different batches can be reliably connected.

[0019] Further, the positioning protrusion is in the shape of a mushroom nail.

[0020] The beneficial effects of the above further scheme are:

[0021] The mushroom nail-shaped positioning protrusion has unique structural advantages. The head is large and the bottom is thin, and when the positioning protrusion is engaged with the fixing hole of the PCB, the large head can form a reliable block in the hole to prevent the positioning protrusion from falling out of the fixing hole, thereby ensuring the stability of the positioning. Moreover, compared with the ordinary columnar positioning block, the mushroom nail-shaped structure has a larger contact area with the wall of the fixing hole, and can generate greater friction force when engaged, thereby further enhancing the positioning effect. In the process of assembling the mobile phone, the obvious shape feature facilitates the workers to quickly identify and align, thereby improving the accuracy and efficiency of the installation. Meanwhile, the design of the mushroom nail-shaped positioning protrusion can also disperse the stress generated during the installation process to a certain extent, thereby avoiding the rupture of the material around the fixing hole of the PCB due to stress concentration, and improving the structural reliability of the PCB.

[0022] The utility model provides a kind of with automatic telescopic function's mobile phone front camera module. With following beneficial effects:

[0023] The connecting piece is engaged and fixed with the main PCB, and the connecting piece is also connected and fixed with the PCB of the camera module, so that the installation process of the whole module is relatively simple, and the module can be firmly installed in the mobile phone and is not easy to loosen.

[0024] The mushroom nail-shaped positioning protrusion on the bottom plate of the connecting piece can be engaged with the fixing hole of the PCB for accurate positioning, so that the position accuracy of the camera module during installation is ensured, and the camera can better play its shooting function.

[0025] The through hole in the upper plate of the connecting piece is filled with adhesive, which further enhances the connection strength between the connecting piece and the PCB, so that the camera module is more reliable during use, and can remain stable even if the mobile phone is subjected to certain vibration or external force.

[0026] The inner diameter of the through hole is larger than the inner diameter of the PCB plate fixing hole, which can provide sufficient space for the injection and filling of the adhesive, so as to ensure that the adhesive can fully play a role, and can also adapt to some errors in the installation process to some extent, improve the compatibility and flexibility of the installation.

[0037] Embodiment one

[0038] The application discloses a front camera module of a mobile phone with an automatic telescopic function, which comprises a PCB board 2, a lens 4 installed on the PCB board 2 through a lifting assembly 3, and connecting pieces 1 arranged on both sides of the PCB board 2, wherein the connecting pieces 1 are located at fixing holes of the PCB board 2, the connecting pieces 1 are provided with fixing plates 101, the connecting pieces 1 are connected and fixed with the PCB board 2 through the fixing plates 101, and the PCB board 2 is clamped and fixed with fixing holes of a main PCB board through the connecting pieces 1. Compared with other connection modes, the clamping and fixing mode is more convenient and fast in the installation process. In the mobile phone production and assembly link, workers only need to align the camera module PCB board with the connecting pieces 1 with the fixing holes of the main PCB board, and press or clamp gently to complete the connection, so that the production efficiency is greatly improved. Moreover, the clamping structure has certain elasticity and toughness, can absorb and buffer the vibration and impact force generated in the use process of the mobile phone to a certain extent, avoids the transmission of too much external force to the camera module due to rigid connection, protects the precise electronic elements in the module from being damaged, and is convenient for dismounting, repairing or replacing the camera module in the later period, and reduces the maintenance cost and difficulty.

[0039] Embodiment two

[0040] In order to ensure the stability of the camera module in the mobile phone and guarantee the reliable work of the camera module, for example, Figures 1 to 4As shown, the utility model further includes: connecting piece 1 is equipped with bottom plate 102, bottom plate 102 is equipped with positioning lug 103, positioning lug 103 is mushroom nail shape, and the mushroom nail shape positioning lug 103 has unique structural advantage. Its head is larger, and the bottom is thinner, and when the PCB board fixing hole is clamped, the larger head can form reliable blocking in the hole, prevent positioning lug 103 from coming out of the fixing hole, and ensure the stability of positioning. Moreover, the mushroom nail structure is larger than the contact area of the ordinary cylindrical positioning block and the fixed hole wall, and can produce greater friction when clamped, further enhancing the positioning effect. In the process of assembling the mobile phone, the obvious shape feature facilitates the workers to quickly identify and align, improves the accuracy and efficiency of installation. At the same time, the design of the mushroom nail-shaped positioning lug 103 can also disperse the stress generated in the installation process to a certain extent, avoid the rupture of the material around the PCB board fixing hole due to stress concentration, improve the structural reliability of the PCB board, and the positioning lug 103 of the bottom plate 102 is clamped with the fixing hole of the PCB board 2 to position the connecting piece 1, and the upper plate 104 is arranged above the bottom plate 102, the through hole 105 is arranged through the upper plate 104, the adhesive is filled in the through hole 105, the setting of the upper plate 104 provides a structural basis for enhancing the connection, and after the adhesive is filled in the through hole 105, the adhesive is tightly combined with the material around the PCB board fixing hole during the curing process, forming a double effect of mechanical occlusion and chemical adhesion. This greatly enhances the connection strength between the connecting piece 1 and the PCB board, effectively prevents the relative displacement of the two due to external factors such as vibration and shaking in daily use, ensures the stability of the camera module in the mobile phone, and ensures its reliable work. At the same time, the adhesive is filled in the through hole 105, which plays a certain protective role for the edge of the fixing hole of the PCB board, reduces the damage of the fixing hole caused by friction, stress concentration and other factors, prolongs the service life of the entire module, and the inner diameter of the through hole 105 is larger than the inner diameter of the fixing hole of the PCB board 2. The through hole 105 with larger inner diameter provides sufficient space for the filling of the adhesive, can accommodate more adhesive, and makes the adhesive better wrap and penetrate around the PCB board fixing hole during the filling process, enhancing the firmness of the connection. At the same time, this size difference allows a certain position error compensation during installation. When the connecting piece 1 is installed with the PCB board, even if the positioning deviates slightly, due to the larger inner diameter of the through hole 105, the adhesive can still be filled smoothly and effectively, improving the fault tolerance and compatibility of installation, and ensuring that the PCB board and connecting piece 1 produced in different batches can be reliably connected.

[0041] Working principle:

[0042] First, the installation of the module is carried out. The connecting piece 1 with a specific structure is connected with the PCB board of the camera module. The connecting piece 1 is provided with a bottom plate 102, and the mushroom-shaped positioning protrusions 103 on the bottom plate 102 are clamped with the fixing holes of the PCB board, so that accurate positioning is realized, and the installation position of the PCB board is ensured to be accurate. At the same time, the connecting piece 1 is further connected and fixed with the PCB board through the fixing plate 101, so that the two are stably combined. Then, the entire camera module is connected with the main PCB board through the connecting piece 1, and the clamping mode of the connecting piece 1 and the fixing holes of the main PCB board is used to complete the preliminary installation of the module in the mobile phone. In this process, the positioning protrusions 103 and the clamping structure are used to simplify the installation steps and ensure the firmness of the installation.

[0043] After the preliminary installation is completed, in order to enhance the connection strength, the upper plate 104 of the connecting piece 1 is operated. The through hole 105 is provided in the upper plate 104, and the inner diameter of the through hole 105 is greater than the inner diameter of the fixing hole of the PCB board. The adhesive is poured in the through hole 105, and the adhesive fills the gap between the through hole 105 and the fixing hole of the PCB board. After curing, the connection strength between the connecting piece 1 and the PCB board is greatly improved, so that the entire camera module is more stable in the mobile phone, and can withstand external forces such as vibration in daily use.

[0044] When the user needs to use the front camera, the mobile phone system sends a command. At this time, the lifting assembly 3 connected with the lens 4 receives the signal and starts to work. The lifting assembly 3 converts electrical energy into mechanical energy through a specific mechanical structure, such as a motor-driven screw nut mechanism or a gear and rack mechanism (determined by the design principle of the lifting assembly 3), to drive the lens 4 to start rising. With the operation of the lifting assembly 3, the lens 4 gradually extends from the inside of the mobile phone to the designated position, ready for shooting work.

[0045] After the lens 4 is extended to the position, the module enters the shooting state. The light is refracted and focused on the image sensor through the lens 4, and the image sensor converts the light signal into an electrical signal. Then, the circuit on the PCB board processes and converts the signal (such as amplification, noise reduction, analog-to-digital conversion, etc.), and finally transmits the processed digital image signal to the mobile phone main processor. The main processor performs subsequent optimization, storage and other operations on the image, and completes the shooting process.

[0046] After the shooting is completed, the mobile phone system sends a command again. The lifting assembly 3 receives the retraction signal and reverses the operation to drive the lens 4 to descend. The lifting assembly 3 uses the mechanical structure to stably retract the lens 4 to the initial position inside the mobile phone, avoiding damage to the lens 4 exposed outside in the non-use state, while maintaining the integrity and aesthetics of the appearance of the mobile phone.
