Camera with anti-shake function

Abstract

The utility model discloses a camera with an anti-shake function, and belongs to the field of cameras, and the camera comprises a housing, an imaging module disposed in the housing, and an elastic suspension assembly disposed in the housing and used for preventing the imaging module from shaking. The elastic suspension assembly is formed by alternately overlapping multiple layers of rubber materials and metal sheets with different elastic coefficients; a self-adaptive damping adjusting mechanism is arranged in the elastic suspension assembly; and a universal joint fixedly connected with the shell is fixedly mounted at the bottom of the imaging module. Compared with optical anti-shake, expensive components such as a complex gyroscope and a compensation lens set are reduced, the efficient anti-shake function can be achieved only through the simple elastic suspension assembly, the self-adaptive damping adjusting mechanism and the universal joint, and the production cost is greatly reduced. As the structure is relatively simple, a large amount of space does not need to be specially reserved for a complex anti-shake mechanism, so that the camera can be designed to be more compact and is suitable for equipment with higher space requirements.

Description

Technical Field

[0001] This application relates to the field of camera technology, specifically a camera with image stabilization. Background Technology

[0002] Currently, camera image stabilization technologies on the market mainly include optical image stabilization (OIS), electronic image stabilization (EIS), and sensor-shift image stabilization (SPS). OIS detects minute movements using a gyroscope within the lens, transmitting the signal to a microprocessor. The processor then controls a compensation lens group to compensate for lens shake based on the direction and amount of displacement, effectively overcoming image blur caused by camera vibration. EIS uses digital algorithms to analyze the image and compensate for shake-induced shifts through methods such as cropping. Sensor-shift image stabilization uses a sensor that shifts accordingly to counteract the effects of shake. However, these existing technologies suffer from drawbacks such as high cost, less-than-ideal stabilization performance in extreme conditions, and large space requirements for the equipment.

[0003] Therefore, this application provides a camera with image stabilization to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a new type of camera with image stabilization function to overcome the above-mentioned shortcomings in the existing technology, and to achieve a more efficient, lower-cost and smaller image stabilization effect through a brand-new design concept.

[0005] To achieve the above objectives, this application provides the following technical solution: a camera with image stabilization function, including a housing, an imaging module disposed within the housing, and an elastic suspension component disposed within the housing for image stabilization of the imaging module;

[0006] The elastic suspension component is composed of multiple layers of rubber materials and metal sheets with different elastic coefficients, stacked alternately. When external vibrations are transmitted to the camera, due to the elastic properties of the rubber materials, the imaging module will adaptively make slight displacements relative to the outer shell under the action of the elastic suspension component. The rubber materials with different elastic coefficients can produce corresponding deformations in response to vibrations of different frequencies and amplitudes, thereby offsetting most of the impact of vibrations on the imaging module and ensuring the stability of the imaging.

[0007] The elastic suspension component is internally equipped with an adaptive damping adjustment mechanism. Compared with optical image stabilization, this invention reduces the need for complex and expensive components such as gyroscopes and compensation lens groups. It achieves efficient image stabilization with only a simple elastic suspension component and adaptive damping adjustment mechanism, greatly reducing production costs.

[0008] Preferably, the adaptive damping adjustment mechanism includes an adjustment groove formed within the elastic suspension assembly, a damping fluid loaded within the adjustment groove, and multiple electromagnetic induction elements disposed within the adjustment groove and immersed in the damping fluid. The electromagnetic induction elements are connected to the camera's control system. By working in conjunction with the elastic suspension assembly, the adaptive damping adjustment mechanism significantly improves image stabilization performance. Real-time dynamic damping adjustment more effectively copes with complex and changing vibration environments, further optimizing image stability and clarity. Moreover, its structure is relatively simple, without introducing too many complex components, reducing costs while ensuring the reliability and durability of the device.

[0009] Preferably, to facilitate the connection between the elastic suspension component and the housing: corresponding mounting slots are provided inside the housing at the corresponding positions of the imaging module, and both ends of the elastic suspension component are respectively fixedly inserted into the two mounting slots. The design of the mounting slots makes the installation process of the elastic suspension component simple and convenient, and easy to achieve mass production. At the same time, the reliable connection ensures that the elastic suspension component will not loosen or fall off during long-term use, ensuring the continuous and stable operation of the camera's image stabilization function.

[0010] Preferably, to ensure the stability of the connection between the rubber material and the metal sheet, the rubber material and the metal sheet are tightly bonded together into a single elastic suspension component through a high-temperature, high-pressure vulcanization process. This bonding process ensures the structural stability and integrity of the elastic suspension component. The stable bonding between the different materials prevents the rubber from separating from the metal during long-term vibration and deformation, ensuring the durability and reliability of its elastic properties, and thus guaranteeing the long-term effective operation of the camera's image stabilization function.

[0011] Preferably, to further enhance the image stabilization effect: a universal joint is fixedly installed at the bottom of the imaging module and fixedly connected to the housing, and a torsion spring is fixedly connected to each rotation axis of the universal joint. The universal joint, in conjunction with the elastic suspension component and the adaptive damping adjustment mechanism, greatly enhances the camera's image stabilization capability in complex vibration environments. It can not only effectively cope with common minor vibrations, but also maintain good image stabilization performance under larger amplitude shaking and different vibration frequencies. Compared with traditional image stabilization technologies, it significantly improves image stability and clarity, providing users with a superior shooting experience.

[0012] Compared to optical image stabilization, this invention reduces the need for complex and expensive components such as gyroscopes and compensation lens assemblies. It achieves efficient image stabilization using only a simple elastic suspension assembly, adaptive damping adjustment mechanism, and gimbal, significantly reducing production costs. Due to its relatively simple structure, it does not require a large amount of space specifically allocated for complex image stabilization mechanisms, allowing for a more compact camera design suitable for space-constrained devices such as ultra-thin smartphones and small drones.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Example

[0020] This embodiment provides a camera with image stabilization function, such as... Figure 1-4 As shown, the camera includes a housing 1, an imaging module 2 disposed within the housing 1, and an elastic suspension component 3 disposed within the housing 1 for stabilizing the imaging module 2.

[0021] The elastic suspension component 3 is composed of multiple layers of rubber materials 31 with different elastic coefficients and metal sheets 32, stacked alternately. When external vibrations are transmitted to the camera, due to the elastic properties of the rubber materials 31, the imaging module 2 will adaptively make a small displacement relative to the outer shell 1 under the action of the elastic suspension component 3. The rubber materials 31 with different elastic coefficients can produce corresponding deformations for vibrations of different frequencies and amplitudes, thereby offsetting most of the impact of vibrations on the imaging module 2 and ensuring the stability of the image. Through the elastic suspension component 3, when the camera is subjected to external vibrations, the imaging module 2 can adaptively make a small displacement relative to the outer shell 1 under the action of the elastic suspension component 3, thereby offsetting most of the impact of vibrations on the image. Compared with traditional image stabilization methods, this structural design does not require complex gyroscopes and other detection components, greatly reducing costs and equipment space requirements. This makes the camera design more compact and better suited for space-constrained devices such as ultra-thin mobile phones and small drones.

[0022] The elastic suspension assembly 3 is internally equipped with an adaptive damping adjustment mechanism 4. The adaptive damping adjustment mechanism 4 includes an adjustment groove 41 within the elastic suspension assembly 3, a damping fluid 42 loaded within the adjustment groove 41, and multiple electromagnetic induction elements 43 disposed within the adjustment groove 41 and immersed in the damping fluid 42. The electromagnetic induction elements 43 are connected to the camera's control system. When the camera detects changes in vibration frequency and amplitude, it controls the current of the electromagnetic induction elements 43 to change the viscosity of the damping fluid 42. For example, when the vibration amplitude is large, the viscosity of the damping fluid 42 is increased, making the displacement of the imaging module 2 more stable; when the vibration frequency is high, the viscosity of the damping fluid 42 is appropriately reduced to ensure that the imaging module 2 can quickly respond to vibration changes. This allows for real-time adjustment of the image stabilization effect according to different vibration conditions, improving the accuracy and adaptability of image stabilization. The adaptive damping adjustment mechanism 4, working in conjunction with the elastic suspension assembly 3, significantly improves image stabilization performance. By dynamically adjusting the damping in real time, it can more effectively cope with complex and changing vibration environments, further optimizing the stability and clarity of the image. Moreover, its structure is relatively simple, without introducing too many complex components, which reduces costs while ensuring the reliability and durability of the equipment. Compared with optical image stabilization, this invention reduces expensive components such as complex gyroscopes and compensation lens groups, and achieves efficient image stabilization function with only a simple elastic suspension component 3 and adaptive damping adjustment mechanism 4, which greatly reduces production costs.

[0023] To facilitate the connection between the elastic suspension component 3 and the outer shell 1, corresponding mounting slots 11 are provided inside the outer shell 1 at the corresponding positions of the imaging module 2. Both ends of the elastic suspension component 3 are fixedly inserted into the two mounting slots 11. This connection method ensures the robustness of the connection between the elastic suspension component 3, the outer shell 1, and the imaging module 2, while allowing the imaging module 2 to move freely under the elastic action of the elastic suspension component 3, thus achieving adaptive displacement during vibration. The design of the mounting slots 11 makes the installation process of the elastic suspension component 3 simple and convenient, facilitating mass production. Simultaneously, the reliable connection ensures that the elastic suspension component 3 will not loosen or fall off during long-term use, ensuring the continuous and stable operation of the camera's image stabilization function.

[0024] To ensure the stability of the connection between the rubber material 31 and the metal sheet 32, the rubber material 31 and the metal sheet 32 ​​are tightly bonded together into a single elastic suspension component 3 through a high-temperature and high-pressure vulcanization process. Under high temperature and high pressure, the rubber material 31 undergoes a vulcanization reaction, its molecular structure changes, and it forms strong chemical bonds and physical interlocking with the metal sheet 32, thus tightly connecting the two together. This connection process ensures the structural stability and integrity of the elastic suspension component 3. The stable bonding between the different materials prevents the rubber from separating from the metal during long-term vibration and deformation, ensuring the durability and reliability of its elastic properties, and thus guaranteeing the long-term effective operation of the camera's image stabilization function. Example

[0025] Unlike Embodiment 1, to further enhance the image stabilization effect, a universal joint 5 fixedly connected to the outer casing 1 is mounted on the bottom of the imaging module 2. Torsion springs 51 are fixedly connected to each rotating shaft of the universal joint 5. When the camera experiences significant shaking, such as tilting, the torsion springs 51, under their own elastic force, drive the imaging module 2 to automatically adjust its posture through the rotating shafts of the universal joint 5, keeping it horizontal. Simultaneously, the structure of the universal joint 5 can absorb vibration energy to a certain extent, reducing the vibration impact force transmitted to the elastic suspension component 3 and lessening the burden on the elastic suspension component 3. The universal joint 5, together with the elastic suspension component 3 and the adaptive damping adjustment mechanism 4, greatly enhances the camera's image stabilization capability in complex vibration environments. It not only effectively copes with common minor vibrations but also maintains good image stabilization performance under significant shaking and different vibration frequencies. Compared to traditional image stabilization technologies, it significantly improves image stability and clarity, providing users with a superior shooting experience.

[0027] The control method in this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply ground is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
