Description

Technical Field

[0001] This invention relates to the field of camera lens control technology, and more particularly to an integrated camera control structure. Background Technology

[0002] The realization of core adjustment functions such as zooming and focusing of camera lenses is inseparable from a stable and reliable integrated control structure. Its performance directly affects the imaging quality and ease of operation of the camera. Therefore, the development of a compact and precise integrated control structure has become an important research direction in the field of cameras.

[0003] In existing technologies, the driving mechanism and axial limiting mechanism of camera lenses are mostly designed independently, and the axial extension and contraction of the lens are constrained by separately set limiting components such as buckles, retaining rings or guide sleeves. The driving component and the limiting component are respectively assembled in different positions of the camera. This split structure not only makes the internal structure of the camera complex and occupies a large installation space, making it difficult to meet the current development needs of miniaturization and thinness of camera devices, but also makes it difficult to ensure the coaxiality of the driving mechanism and the limiting mechanism during assembly. Summary of the Invention

[0004] In view of this, this application proposes an integrated camera control structure with a tight fit, high lens adjustment accuracy and transmission efficiency.

[0005] This invention provides the following technical solution: an integrated camera control structure, characterized in that it includes: a lens gear, a drive motor, and an axial limiting ring; The lens gear has a ring-shaped gear structure, which is suitable for meshing with camera lenses; The drive motor is located below the lens gear, and a motor gear is provided above it. The motor gear meshes with the lens gear, and the drive motor drives the motor gear and the lens gear to rotate. The axial limiting ring is a circular structure located above the lens gear, and the axial limiting ring and the lens gear are on the same axis. It is fixed on the camera lens and can move up and down with the camera lens.

[0006] In one embodiment of the invention, an axial limiting rod is also included. The axial limiting rod is a long cylindrical structure, and its length direction is parallel to the axis of the lens gear.

[0007] In one embodiment of the invention, a connecting portion is provided on one side of the axial limiting ring along the thickness direction. The connecting portion is integrally connected to the axial limiting ring, and the connecting portion has a vertically formed circular through hole that cooperates with the axial limiting rod.

[0008] In one embodiment of the invention, the axial limiting rod passes vertically through the circular through hole, and a limiting rod seat is installed at the bottom of the axial limiting rod to fix the axial limiting rod.

[0009] In one embodiment of the invention, the axial limiting ring has a certain thickness, and a strip-shaped groove is formed on the upper surface of the axial limiting ring. The depth of the strip-shaped groove is less than the thickness of the axial limiting ring, and there are three strip-shaped grooves, which are evenly spaced along the axial limiting ring.

[0010] In one embodiment of the invention, an adapter ring is also included. The adapter ring is a circular plate-shaped structure located below the axial limiting ring and is bolted to the axial limiting ring. The inner ring of the adapter ring is provided with an internal thread, and the outer ring is provided with an external thread. The adapter ring is provided with a shoulder in the axial direction. The shoulder is formed by the axial height difference between the internal thread and the external thread.

[0011] In one embodiment of the invention, two limit switches are also included; The two limit switches are located below the lens gear, forming a circular hollow structure together with the drive motor, and there is a certain gap between the limit switches and the drive motor.

[0012] In one embodiment of the invention, a metal block is provided on the inner side of the lens gear. The metal block is a rectangular block structure that extends downward in the length direction to the top of the limit switch, and the metal block is bolted to the lens gear.

[0013] In one embodiment of the invention, a circumferential fixing member is also included; The three circumferential fixing components are rectangular plate-shaped structures with an arc, and are respectively fixed to the drive motor and the two limit switches.

[0014] In one embodiment of the invention, a bottom shell is also included. The bottom shell is a ring-shaped plate structure, and the drive motor, two limit switches and the axial limit rod are sequentially fixed on the top of the ring along its circumference.

[0015] The beneficial effects of this invention are as follows: The direct meshing transmission design between the motor gear and lens gear eliminates the need for traditional intermediate transmission components, reducing power transmission loss and accumulated errors, and significantly improving the response speed and rotational accuracy of lens adjustment. The axial limiting ring, with a preset thickness along the axial direction, upper and lower surfaces, and coaxially arranged with the lens gear and fixed to the camera lens, moving up and down synchronously with the lens, precisely constrains the axial movement trajectory of the lens, preventing misalignment during adjustment and ensuring transmission stability. In particular, the axial limiting ring is designed to be directly installed on the original camera lens cap, requiring no modification to the original camera and preserving its original performance to the greatest extent. The overall integrated layout is streamlined and compact, effectively reducing the internal space occupied by the camera, adapting to miniaturization design requirements, simplifying assembly processes, reducing component wear, and lowering production and maintenance costs. Simultaneously, the tight fit of each component achieves a high degree of efficiency in terms of precision, stability, and practicality.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0023] This application discloses an integrated camera control structure for focusing control of SLR camera lenses, enabling convenient operation for high-quality imaging through precise lens adjustment.

[0024] Specific references Figure 1 As an integrated camera control structure of the present invention, the device includes: a lens gear 100, a drive motor 200, and an axial limiting ring 300. The lens gear 100 is a ring-shaped gear structure suitable for meshing with a camera lens 1; the drive motor 200 is located below the lens gear 100, and a motor gear 210 is arranged above it. The motor gear 210 meshes with the lens gear 100, and the drive motor 200 drives the motor gear 210 and the lens gear 100 to rotate; the axial limiting ring 300 is a ring-shaped structure with a preset thickness along the axial direction, having an upper surface and a lower surface, located above the lens gear 100, and the axial limiting ring 300 and the lens gear 100 are located on the same axis, fixed to the camera lens 1, and can move together with the camera lens 1.

[0025] In this example, such as Figure 4 As shown, the lens gear 100 has a ring-shaped gear structure, specifically a hollow ring with teeth on the outer ring, and a certain thickness along the axial direction. The inner surface of the lens gear 100 has grooves that match the stripes on the outer circumference of the camera lens 1, allowing the lens gear 100 to be precisely engaged with the camera lens 1. This ensures no relative slippage between the lens gear 100 and the camera lens 1, improving the stability and reliability of the transmission. Furthermore, the meshing of the external teeth with the motor gear 210 achieves tight transmission, effectively reducing power transmission loss.

[0026] Specifically, the lens gear 100 has uniformly distributed external teeth on its outer surface, enabling it to mesh with the motor gear 210 on the drive motor 200 without backlash. The upper surface of the lens gear 100 has a plurality of uniformly distributed grooves 110, which are spaced apart along the circumference. The number of grooves can be determined according to the diameter of the lens gear 100; in this application, six grooves 110 are preferred. The width of the grooves 110 extends from near the inner ring to near the outer ring, and the depth is less than the thickness of the lens gear 100. The grooves 110 reduce the overall weight of the lens gear 100.

[0027] In addition, in this embodiment, the fixation between the camera lens 1 and the lens gear 100 can be strengthened by attaching adhesive strips to the outer peripheral surface of the camera lens 1.

[0028] Furthermore, the upper surface of the lens gear 100 is adjacent to the axial limiting ring 300, with a gap between them and no direct contact. The lower surface is in contact with the drive motor 200, and the external teeth of the lens gear 100 mesh with the motor gear 210. The axes of the lens gear 100 and the axial limiting ring 300 are completely coincident with the axis of the camera lens 1.

[0029] In this example, the lens gear 100 consists of two semi-circular gears, which are fixedly connected by bolts. The bolts are oriented perpendicular to the axis of the lens gear 100. At the bolted connection between the two semi-circular gears, two support rods 130 extend downwards. Each support rod 130 is a long, narrow structure, with its bottom end fixedly connected to the base shell 700 and its top end fixedly connected to the lens gear 100, thus supporting the lens gear 100.

[0030] like Figure 1As shown, the drive motor 200 is located below the lens gear and has a vertical cylindrical structure. A short shaft extends upward from the top, and a motor gear 210 is fixed at the top of the short shaft. The motor gear 210 is a small ring-shaped gear and is coaxial with the drive motor 200. The drive motor 200 is externally fitted with a motor housing 220, the bottom of which is completely flush with the bottom housing 700. The position of the motor gear 210 corresponds perfectly to the outer ring gear of the lens gear 100. The tooth surfaces of the motor gear 210 mesh with the tooth surfaces of the lens gear 100 without any backlash. Furthermore, the outer diameter of the motor gear 210 is much smaller than that of the lens gear 100, allowing for speed reduction transmission by driving the larger gear with the smaller gear, thus improving the stability of lens adjustment. When the drive motor 200 receives a control signal, it transmits power to the motor gear 210 through the motor shaft. Because the motor gear 210 and lens gear 100 mesh precisely without any backlash, the rotation of the motor gear 210 directly drives the lens gear 100 to rotate circumferentially. Considering that the outer diameter of the motor gear 210 is much smaller than that of the lens gear 100, a reduction ratio is formed, which reduces the rotational speed of the lens gear 100, thereby achieving precise control over the telescopic movement of the camera lens 1. This transmission structure has no intermediate connecting parts, which not only reduces the accumulation of transmission errors but also improves response speed and control accuracy, making the camera lens 1 move smoothly and be accurately positioned during focusing, effectively avoiding the gap, vibration, and noise problems existing in traditional multi-stage transmission structures.

[0031] The axis of the drive motor 200 is parallel to the axis of the lens gear 100. The motor housing 220 is a rectangular box structure that can accommodate the drive motor 200. The sides of the motor housing 220 are fitted with the retaining member 600, and the bottom is fixed to the bottom shell 700 by bolts. The retaining member 600 will be described in detail later. When the drive motor 200 is powered on and rotates, the motor gear 210 rotates synchronously, driving the lens gear 100 to rotate through meshing, thereby driving the camera lens 1 to extend or retract, realizing zoom or focus adjustment. The entire transmission path has no intermediate parts and no additional transmission structure. Furthermore, the motor housing 220 can be made of metal, which has a certain heat dissipation performance. The heat dissipation capacity can also be enhanced by adding a hollow structure to the side of the motor housing 220.

[0032] like Figure 5As shown, the axial limiting ring 300 has a circular ring structure, and its overall shape is similar to that of the lens gear 100, but its outer surface is toothless, and its inner surface is fixedly connected to the top of the camera lens 1. The axial limiting ring 300 is coaxially arranged with the lens gear 100. The inner diameter of the axial limiting ring 300 is slightly larger than the outer diameter of the camera lens 1, and its outer diameter is close to that of the lens gear 100. The axial limiting ring 300 has a certain thickness along the axial direction to ensure that it is not easily deformed under force. Three strip-shaped grooves 310 are evenly formed on its upper surface. The strip-shaped grooves 310 are distributed at intervals along the circumference, and the included angle between adjacent grooves is 120°. The length of the grooves extends from near the inner ring to near the outer ring, and the depth is less than the thickness of the axial limiting ring 300. These strip-shaped grooves reduce the overall weight of the axial limiting ring 300 and avoid increasing the burden on the lens extension and retraction. When the camera lens 1 extends and retracts up and down under the rotation of the lens gear 100, the axial limiting ring 300 moves together with the front end of the lens. Its inner ring is always in contact with the lens 1, and its outer ring is not obstructed by other parts. This follow-up structure precisely constrains the axial movement trajectory of the lens, preventing deviation during lens adjustment. The axial limiting ring 300 can be made of plastic, which has the advantages of being lightweight and having low friction, reducing the burden of movement when moving with the camera lens 1.

[0033] In particular, the axial limiting ring 300 is designed to be directly installed on the snap-fit ​​position of the original camera lens cap. Its outer diameter and connection structure are precisely matched with the original camera lens cap. It can be installed without any modification to the original camera, which not only ensures the original performance of the camera, but also achieves precise control of the lens.

[0034] In one specific embodiment, an axial limiting rod 320 is also included. The axial limiting rod 320 is a long cylindrical structure, and its length direction is parallel to the axis of the lens gear 100. The bottom of the axial limiting rod 320 is fixed, and its top is slidably connected to the axial limiting ring 300 to limit the radial displacement of the axial limiting ring 300.

[0035] specifically refer to Figure 2 The axial limiting rod 320 has an elongated cylindrical structure, with a slender cylindrical body whose length direction is parallel to the axis of the lens gear 100. The axial limiting rod 320 is only located on one side of the axial limiting ring 300. The rod body has a small diameter and a smooth surface, allowing it to engage with the connecting part 330 of the axial limiting ring 300 to achieve limiting. Both the axis of the axial limiting rod 320 and the axis of the lens gear 100 are vertical lines, and the distance between them is fixed, ensuring that the axial limiting rod 320 can constrain the radial movement of the axial limiting ring 300. When the axial limiting ring 300 extends or retracts with the lens 1, the axial limiting rod 320 can restrict the limiting ring 300 from shifting in an unintended direction, preventing misalignment of the lens 1 during adjustment.

[0036] In one specific embodiment, a connecting part 330 is provided on one side of the axial limiting ring 300 along the thickness direction. The connecting part 330 is sleeved on the axial limiting rod 320, and the connecting part 330 is vertically provided with a circular through hole 303, which cooperates with the axial limiting rod 320.

[0037] like Figure 5 As shown, the connecting part 330 is an integral structure of the axial limiting ring 300, in the shape of a rectangular block, extending downwards along the thickness direction from one side of the axial limiting ring 300. It is made of the same material as the axial limiting ring 300. A circular through hole 303 is vertically formed at the center of the connecting part 330. The inner diameter of the circular through hole 303 matches the diameter of the axial limiting rod 320, and the axis of the through hole 303 is parallel to the axis of the axial limiting ring 300, ensuring that the axial limiting rod 320 can pass vertically through. The length and width of the connecting part 330 are both smaller than the outer diameter of the axial limiting ring 300 to avoid interference with other components. The axial limiting rod 320 passes vertically through the circular through hole 303 of the connecting part 330, with the rod body fitting against the inner wall of the through hole. The connecting part 330 and the axial limiting ring 300 are integral and can slide up and down along the axial limiting rod 320. This mating structure can limit the radial displacement of the axial limiting ring 300 to a very small range.

[0038] In one specific embodiment, a limit rod seat 321 is installed at the bottom of the axial limit rod 320 to fix the axial limit rod 320. Figure 3 As shown, the limiting rod seat 321 is an arc-shaped block structure, with dimensions that match the bottom shell 700. Its bottom is flush with the bottom shell 700, and its top is fixedly connected to the bottom of the axial limiting rod 320. The limiting rod seat 321 is fixed to the bottom shell 700 by bolts.

[0039] In one specific embodiment, an adapter ring 400 is also included. The adapter ring 400 is a circular plate structure located below the axial limiting ring 300 and bolted to the axial limiting ring 300. The adapter ring 400 has threaded holes corresponding to the slotted groove 310 for fixed connection with the axial limiting ring 300. The adapter ring 400 has an inner ring and an outer ring, with the inner ring being higher than the outer ring. The height of the inner and outer rings forms a stepped surface, which fits against the lower surface of the axial limiting ring 300. The inner ring of the adapter ring 400 has internal threads for mounting a lens UV filter, and the outer ring has external threads for threaded connection with the camera lens 1. The adapter ring 400 is a transition component connecting the axial limiting ring 300 and the camera lens 1. It has a circular plate structure, is a flat ring with a thin thickness, is located below the axial limiting ring 300, fits against the axial limiting ring 300, and is fixed to the axial limiting ring 300 by bolts. In this embodiment of the application, six threaded holes are provided at the positions of the three strip grooves 310 corresponding to the axial limiting ring 300.

[0040] The adapter ring 400 is bolted to the axial limiting ring 300 through this threaded hole. The inner ring of the adapter ring 400 has internal threads for mounting the lens UV filter, and the outer ring has external threads for threaded connection with the camera lens 1. The axial height difference between the inner and outer rings forms a stepped surface, and the inner ring of the adapter ring 400 is slightly higher than the outer ring. This stepped surface can fit against the lower surface of the axial limiting ring 300 to ensure positioning accuracy when the two are connected.

[0041] In one specific embodiment, this application also includes two limit switches 500. The two limit switches 500 are located below the lens gear 100, and together with the drive motor 200, they form a circular hollow structure, with a certain gap between the limit switches 500 and the drive motor 200.

[0042] like Figure 2 As shown, the limit switches 500 are components for controlling the lens travel. There are two of them, each with a rectangular block structure. The bottom of the limit switches 500 is attached to the bottom housing 700 and fixed to it with bolts. The two limit switches 500 are located on both sides of the drive motor 200, and are evenly distributed around the bottom housing 700, forming a circular hollow structure. The inner diameter of this hollow area is adapted to the outer diameter of the camera lens 1 to accommodate the lens. A gap is left between the two limit switches 500 and the motor housing 220. This gap can prevent collisions caused by vibration during operation and provide sufficient space for the rotation of the lens gear 100.

[0043] In this example, a small sensor 510 is provided at the top of the limit switch 500. The sensor 510 has a sensing end at the top, which faces downwards from the lens gear 100. It is used to receive the trigger signal from the metal block 120 below the lens gear 100. Detailed information about the metal block 120 will be described below.

[0044] In one specific embodiment, a metal block 120 is provided inside the lens gear 100. The metal block 120 is a rectangular block structure that extends downward in the length direction to the top of the limit switch 500, and the metal block 120 is bolted to the lens gear 100.

[0045] like Figure 3As shown, the metal block 120 is a component that triggers the limit switch 500. It has a rectangular block structure, with a slender rectangular body extending downwards in the length direction. The top is fixed to the inside of the lens gear 100 by bolts, and the bottom extends to the top of the limit switch 500. The metal block 120 is made of metal, and its length direction is parallel to the axis of the lens gear 100. When the lens gear 100 rotates to its limit position, the metal block 120 rotates synchronously with the gear. The lower end of the metal block 120 contacts the sensing end of the limit switch 500, triggering the switch to operate and thus controlling the drive motor 200 to stop. This structure effectively prevents the camera lens 1 from being damaged due to excessive extension or contraction.

[0046] In one specific embodiment, it also includes a circumferential fixing member 600. The circumferential fixing member 600 is a rectangular plate-shaped structure with an arc, and there are three of them, which are respectively fixed to the drive motor 200 and the two limit switches 500.

[0047] like Figure 3 As shown, the circumferential fixing component 600 is rectangular with curved edges. One side of the curved edge perfectly matches the motor housing 220 or the limit switch 500, allowing for a tight fit. The other side of the curved edge fits the outer surface of the camera lens 1, assisting in fixing the camera lens 1. Bolt holes are provided on the circumferential fixing component 600 for fixed connection with the motor housing 220 or the limit switch 500. One of the circumferential fixing components 600 has its curved edge fitted to the motor housing 220, while the other two are fitted to the two limit switches 500 respectively.

[0048] In one specific embodiment, such as Figure 1 As shown, it also includes a bottom shell 700, which is a ring-shaped plate structure. A drive motor 200, two limit switches 600 and an axial limit rod 320 are fixed in sequence along its circumference on the top of the bottom shell 700.

[0049] The base shell 700 serves as the mounting base for the entire structure. It is a ring-shaped plate with a flattened ring body. Its outer diameter is close to that of the axial limiting ring 300, and its inner diameter matches the outer diameter of the camera lens 1. It has an upper and lower surface. The upper surface is the mounting surface, where the drive motor 200, two limit switches 500, and a limit rod seat 321 are vertically fixed circumferentially. The base shell 700 is a hollow structure, through which the camera lens 1 passes vertically, located at the center of the entire control structure. All functional components, including the drive motor 200, limit switches 500, and axial limiting rod 320, are evenly distributed around the camera lens 1 along the circumference of the base shell 700, and the mounting direction of each component is perpendicular to the upper surface of the base shell 700. The base shell 700, as the mounting base for the entire structure, is a ring-shaped plate with a flattened ring body. Its outer diameter is close to that of the axial limiting ring 300, and its inner diameter matches the outer diameter of the camera lens 1. It has sufficient thickness to ensure structural rigidity.

[0050] Specifically, along the circumferential direction of the base shell 700, there are, in sequence, a drive motor 200, a first limit switch 500, a second limit switch 500, and a limit rod seat 500, with uniform distances between each component. The base shell 700 is made of metal or high-strength plastic, possessing sufficient rigidity to support the weight of all components without deformation.
