A camera module and camera device

Abstract

This invention discloses a camera module and camera device, including a camera body, a lens base fixedly connected to the outer wall of the camera body, and a cavity opened inside the lens base. The lens body is movably installed inside the lens base, and a mounting ring is fixedly sleeved on the outer ring of the lens body. A silicone ring is fixed inside the lens base. The device also includes: a driving and linkage mechanism; a locking mechanism; a stabilizing mechanism; and a positioning mechanism. This invention activates a micro motor to drive the drive shaft, which, through gear and belt transmission, drives the remaining three shafts to rotate. This, in turn, drives the rotating plate fixedly sleeved on the outer ring of the shaft to rotate. The rotation of the rotating plate causes the locking block to disengage from its corresponding slot, facilitating subsequent disassembly of the lens body. This can be operated with one hand. When the locking block engages in its corresponding slot, the lens body and lens base are installed. The entire installation process does not involve torsion, ensuring that it will not loosen even after multiple subsequent installations and disassemblies.

Description

Technical Field

[0001] This invention relates to the field of camera devices, and more specifically to a camera module and camera device. Background Technology

[0002] A complete camera module mainly consists of three parts: lens, image sensor, and image processor. The lens and image sensor together are called the lens module. When using a camera to shoot, a corresponding camera module needs to be installed according to different usage requirements to capture images. The lens is usually connected to the lens base by threads to ensure the stability of the lens.

[0003] A Chinese patent publication number, CN211603662U, discloses a camera module including a lens and a lens base for fixing the lens. The lens has a stepped screw, and the inner wall of the lens base, which is adapted to the screw, is also stepped. The lens screw has a first external thread and a second external thread spaced apart, with the thread diameter of the first external thread being larger than that of the second external thread. The lens base has a first internal thread that matches the first external thread and a second internal thread that matches the second external thread. In this embodiment, the lens and lens base are assembled using a double-threaded connection, reducing the number of rotations required when the lens is screwed into the lens base. This reduces friction between the threads, thus reducing debris generation. Furthermore, the double-threaded design provides greater stability than a single-threaded design.

[0004] While the aforementioned lens module employs a dual-segment thread design to enhance the fixation of telephoto lenses during installation, several issues remain: The continuous rotation of the knob during lens installation leads to cumbersome operation, and the continuous friction between the external and internal threads causes wear. Furthermore, vibration at the connection point can cause the threaded connection to loosen and become unstable over time, thus affecting the lens's future usability.

[0005] Therefore, it is necessary to invent a camera module and camera device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a camera module and camera device to solve the problems mentioned in the background art, such as the cumbersome installation operation caused by continuous knob installation of the lens, the wear caused by continuous friction between the external and internal threads, and the vibration at the connection point, which can lead to loosening and instability of the threaded connection after a long period of use, thus affecting the subsequent use of the lens.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a camera module and camera device, comprising a camera body, a lens base fixedly connected to the outer wall of the camera body, and a cavity opened inside the lens base, a lens body movably installed inside the lens base, and an mounting ring fixedly sleeved on the outer ring of the lens body, and a silicone ring fixed inside the lens base, and further comprising: a driving and linkage mechanism, a micro motor fixedly attached to the outer wall of the lens base, and a drive shaft driven by the output shaft of the micro motor, and a gear fixedly sleeved on the outer ring of the drive shaft;

[0012] Preferably, the driving and linkage mechanism includes:

[0013] A miniature motor is fixed to the outer wall of the lens base, and the output shaft of the miniature motor passes through the side plate of the lens base into the cavity;

[0014] The drive shaft has one end that penetrates the inner wall of the cavity, and the drive shaft and the through-hole are rotatably connected by a bearing. The other end of the drive shaft is connected to the output shaft of the micro motor.

[0015] Gear 1 and Gear 2, wherein Gear 1 is fixedly sleeved on the outer ring of the drive shaft, and Gear 1 and Gear 2 are meshed and connected.

[0016] The linkage shaft has two ends that pass through the inner walls of the two sides of the cavity, and the linkage shaft is rotatably connected to the through opening by bearings. The linkage shaft is fixedly sleeved on the inner ring of the second gear, and the linkage shaft is distributed parallel to the drive shaft.

[0017] Rotating shaft one and rotating shaft two, with two bearings distributed in parallel, and the ends of both shafts penetrating the inner walls of both sides of the cavity, and rotating shaft one and rotating shaft two are rotatably connected to the through opening through bearings. Rotating shaft one and rotating shaft two, as well as the drive shaft and linkage shaft are distributed in parallel.

[0018] The belts are provided in two parts. The two ends of one belt are respectively connected to the pulleys fixedly sleeved on the outer ring of the drive shaft and the rotating shaft. The two ends of the other belt are respectively connected to the pulleys fixedly sleeved on the outer ring of the linkage shaft and the rotating shaft.

[0019] Preferably, the engaging mechanism includes:

[0020] There are four rotating plates, which are fixedly sleeved on the outer rings of the drive shaft, the linkage shaft, the first rotating shaft, and the second rotating shaft. The two rotating plates on the outer rings of the linkage shaft and the first rotating shaft are symmetrically distributed, and the two rotating plates on the outer rings of the first rotating shaft and the second rotating shaft are symmetrically distributed.

[0021] The locking block is triangular in shape, with one end fixedly connected to the rotating plate and the other end being pointed. The locking block matches the pre-set slot inside the mounting ring, and the bottom of the locking block also has a pre-set slot.

[0022] Preferably, the stabilizing mechanism includes:

[0023] The movable groove is located inside the mounting ring, and its position corresponds to the position of the preset slot at the bottom of the card block.

[0030] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0031] The micro motor is started to drive the drive shaft, which in turn drives the remaining three shafts to rotate through the transmission of gears and belts. This, in turn, drives the rotating plate that is fixedly sleeved on the outer ring of the shaft to rotate. The rotation of the rotating plate causes the locking block to move out of the corresponding slot, which facilitates the subsequent disassembly of the lens body. It can be operated with one hand. When the locking block is engaged in the corresponding slot, the lens body and lens base are installed. The entire installation process does not involve torsion, which maximizes the guarantee that it will not loosen even after multiple subsequent installations and disassemblies.

[0032] After the locking block is engaged in the corresponding slot, the movable rod simultaneously engages in the corresponding slot inside the locking block, providing secondary reinforcement to the locking block. This ensures the stability of the engagement between the locking block and the mounting ring that secures the rotating plate to the outer ring of the lens body. Attached Figure Description

[0049] The lens base 2 has a through cylindrical hole inside, and the diameter of the cylindrical hole is equal to the outer diameter of the mounting ring 4. The lens base 2 also has a "C" shaped cavity 5 inside.

[0050] The drive and linkage mechanism 6 includes:

[0051] A micro motor 601 is fixed to the outer wall of the lens base 2, and the output shaft of the micro motor 601 passes through the side plate of the lens base 2 into the cavity 5.

[0052] The drive shaft 602 has one end that penetrates the inner wall of the cavity 5, and the drive shaft 602 is rotatably connected to the through opening by a bearing. The other end of the drive shaft 602 is connected to the output shaft of the micro motor 601 for driving the drive shaft 602 to rotate.

[0053] Gear 1 603 and gear 2 604, gear 1 603 is fixedly sleeved on the outer ring of drive shaft 602, and gear 1 603 and gear 2 604 are meshed and connected.

[0054] The linkage shaft 605 has two ends that pass through the inner walls of both sides of the cavity 5, and the linkage shaft 605 is rotatably connected to the through opening by bearings. The linkage shaft 605 is fixedly sleeved on the inner ring of the gear 604, and the linkage shaft 605 is parallel to the drive shaft 602. The linkage shaft 605 is synchronously driven to rotate through gear transmission, and the rotation direction of the linkage shaft 605 is opposite to the rotation direction of the drive shaft 602.

[0055] Rotating shaft 1 606 and rotating shaft 2 607, with two bearings distributed in parallel, and both ends penetrating the inner walls of both sides of cavity 5, and rotating shaft 1 606 and rotating shaft 2 607 are rotatably connected to the through opening through bearings. Rotating shaft 1 606 and rotating shaft 2 607, as well as drive shaft 602 and linkage shaft 605 are distributed in parallel.

[0056] Two belts 608 are provided. The two ends of one belt 608 are respectively connected to the pulleys fixedly sleeved on the outer ring of the drive shaft 602 and the first rotating shaft 606. The two ends of the other belt 608 are respectively connected to the pulleys fixedly sleeved on the outer ring of the linkage shaft 605 and the second rotating shaft 607. The rotation of the drive shaft 602 and the linkage shaft 605 synchronously drives the rotation of the first rotating shaft 606 and the second rotating shaft 607, thereby driving the locking block 702 below the mounting ring 4 to move and engage.

[0057] Card-connecting mechanism 7 includes:

[0058] There are four rotating plates 701, which are respectively fixedly sleeved on the outer ring of the drive shaft 602, the linkage shaft 605, the first rotating shaft 606 and the second rotating shaft 607. The two rotating plates 701 on the outer ring of the linkage shaft 605 and the first rotating shaft 606 are symmetrically distributed, and the two rotating plates 701 on the outer ring of the first rotating shaft 606 and the second rotating shaft 607 are symmetrically distributed.

[0059] The locking block 702 is triangular in shape, with one end fixedly connected to the rotating plate 701 and the other end being pointed. The locking block 702 matches the pre-set slot inside the mounting ring 4. The bottom of the locking block 702 also has a pre-set slot, which is used to limit the mounting ring 4, thereby limiting the lens body 3 that is fixedly sleeved on the inner ring of the mounting ring 4.

[0060] The stabilizing agencies include 8;

[0061] The movable slot 801 is located inside the mounting ring 4, and the position of the movable slot 801 corresponds to the position of the preset slot at the bottom of the card block 702.

[0062] The movable rod 802 has a pointed cone shape at the top, and the tip of the movable rod 802 matches the pre-set slot at the bottom of the locking block 702. The left and right sides of the bottom end of the movable rod 802 are fixedly connected to protrusions, and the movable rod 802 and the protrusions are movably connected to the movable groove 801, so that the movable rod 802 can be engaged in the matching slot inside the locking block 702 as the locking block 702 moves, ensuring that the locking block 702 is stably engaged.

[0063] Spring 803 is fixedly connected at both ends to the bottom end of movable rod 802 and the inner wall of movable groove 801, respectively, and is used to control the movement and reset of movable rod 802.

[0064] Positioning mechanism 9 includes:

[0065] The positioning rod 901 is L-shaped, and one end of the positioning rod 901 is fixedly connected to the inner wall of the through hole inside the lens base 2.

[0066] The positioning groove 902 matches the end of the positioning rod 901, and the positioning groove 902 is opened inside the mounting ring 4. It is used to control the final position of the lens body 3 inside the lens base 2, so that the locking block 702 can be accurately engaged in the matching slot inside the mounting ring 4.

[0067] The inner ring of the silicone ring 10 is pointed, and the inner ring of the silicone ring 10 contacts the outer ring of the lens body 3 and is tightly attached to the outer ring of the lens body 3. The silicone ring 10 has a certain degree of toughness. When the lens body 3 is pushed into the lens base 2, the silicone ring 10 blocks dust. The silicone ring 10 wrapped around the outer ring of the lens body 3 also prevents external light sources from entering the lens base 2 and causing light leakage.

[0068] Working principle: When using a camera module and camera device, firstly, when the camera module needs to be replaced, the micro motor 601 is started to drive the drive shaft 602, which is connected to the output shaft, to rotate. This, in turn, drives the gear 603, which is fixedly sleeved on the outer ring of the drive shaft 602, to rotate. The gear 603 simultaneously drives the gear 604, which meshes with it, and the linkage shaft 605, which is fixedly sleeved on the inner ring of the gear 604, to rotate synchronously. Since the gears mesh in opposite directions, the drive shaft 602 and the linkage shaft 605 rotate in opposite directions. At the same time, driven by the two sets of belts 608, the drive shaft 602 synchronously drives the rotating shaft 606 to rotate, and the linkage shaft 605 synchronously drives the rotating shaft 607 to rotate. This, in turn, drives the four rotating plates 701, which are fixedly sleeved on the outer rings of the drive shaft 602, the linkage shaft 605, the rotating shaft 606, and the rotating shaft 607, to rotate. Figure 3Taking the position of the rotating plate 701 as an example, the drive shaft 602 and the linkage shaft 605 rotate in opposite directions, causing the two rotating plates 701 to rotate synchronously and open. Similarly, the rotating shaft 1 606 and the rotating shaft 2 607 rotate synchronously, causing the rotating plates 701 on the outer ring of the rotating shaft 1 606 and the rotating plates 2 607 to also open. During the rotation of the rotating plate 701, the triangular locking block 702 fixedly connected to the outer wall of the rotating plate 701 is driven to leave the matching slot inside the mounting ring 4. (Refer to...) Figure 7 During the process of the locking block 702 leaving the slot, the conical slot inside the locking block 702 that matches the movable rod 802 moves with the locking block 702. The inner wall of the conical slot abuts against the top of the conical movable rod 802, thus pushing the movable rod 802 towards the movable groove 801. This compresses the spring 803, causing it to deform. At this time, the movable rod 802 gradually leaves the conical slot inside the locking block 702 that matches it. The locking block 702 then completely leaves the slot inside the mounting ring 4 that matches it, making it easy to remove the lens body 3.

[0069] When it is necessary to install the lens body 3, simultaneously start the micro motor 601 to drive the rotating plate 701 to unfold, and hold the lens body 3 so that its tail end passes through the silicone ring 10 and enters the through hole inside the lens base 2. Push the lens body 3 into the lens base 2. At this time, the silicone ring 10, which has a certain degree of toughness, wraps around the outer ring of the lens body 3. When pushing the lens body 3 into the lens base 2, the silicone ring 10 can also block some dust from the outside. At the same time, the silicone ring 10 wrapping around the outer ring of the lens body 3 also prevents external light sources from entering the lens base 2 and causing light leakage, which would affect the final image quality. When pushing the lens body 3, the positioning groove 902 inside the mounting ring 4 is fitted onto the outer ring of the positioning rod 901. At this time, it is not necessary to push the lens body 3 anymore. Start the micro motor 601 to rotate in the opposite direction, and repeat the above operation steps. At this time, two sets of four pieces The rotating plates 701 move towards each other, and the locking block 702, which is fixedly connected to the outer wall of the rotating plates 701, moves into the matching slot inside the mounting ring 4. As the locking block 702 rotates synchronously with the rotating plates 701, the front end of the locking block 702 abuts against the conical top of the movable rod 802, which is movably connected to the movable groove 801 inside the mounting ring 4. As the locking block 702 moves, it abuts against the movable rod 802 and moves towards the inside of the movable groove 801, while simultaneously compressing the spring 803. After the locking block 702 is fully engaged in the slot inside the mounting ring 4 as the rotating plates 701 move, the matching slot inside the locking block 702 moves to the top of the movable rod 802. Under the pushing force of the spring 803, the movable rod 802 is pushed into the matching slot inside the locking block 702, thus ensuring the stability of the locking block 702 and the stability of the lens body 3 installation.

[0070] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
