Abstract
Description
Technical Field
[0001] This utility model relates to the field of camera protection technology, and in particular to an automatic opening and closing mechanism for a camera protection device. Background Technology
[0002] With the development of industrial automation and intelligence, cameras are increasingly widely used in industrial production, quality inspection, logistics management and other fields. However, in practical applications, camera lenses often need to work in harsh environments, such as in the presence of pollutants such as water vapor, dust, and oil. These pollutants can easily adhere to the camera lens, leading to a decrease in image quality and affecting subsequent image processing and recognition.
[0003] However, existing camera protection devices still have some shortcomings. First, many fixed protection devices lack automatic switching functions, failing to automatically open or close the protective cover according to the camera's operating status. This results in either long-term exposure of the lens to contamination or the need for manual intervention to operate the protective cover, affecting work efficiency. Furthermore, existing linkage mechanisms are often complex in structure with multiple transmission links, making them prone to jamming or unstable transmission, affecting the reliability and accuracy of opening and closing.
[0004] Especially in the internal environment of equipment where air blowing occurs, camera lenses are easily contaminated by water stains, leading to abnormal or failed image captures, which seriously affects the success rate of barcode scanning and production efficiency. Existing protection devices struggle to ensure dynamic protection while also being simple in structure, easy to maintain, and cost-effective, failing to meet the industrial field's demands for high reliability, high efficiency, and low maintenance costs for camera protection devices.

[0014] Furthermore, the conversion mechanism is a linkage group, including at least two linkages, forming a four-bar linkage to improve motion stability and opening / closing accuracy.
[0015] Furthermore, the protective component is mounted in front of the camera lens via a rotating or sliding joint.
[0016] Furthermore, the protective component is a protective cover, including a first protective cover and a second protective cover, which are symmetrically installed on both sides of the camera lens via a rotating joint. The other end of the conversion mechanism is connected to the rotating joint for transmission, driving the protective cover to rotate and open around the rotating joint.

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] This utility model protects an automatic opening and closing mechanism for a camera protection device, such as... Figures 1-3 As shown, it includes:
[0033] Drive unit 1 is used to provide linear driving force;
[0034] Transmission component 2 is connected to the output end of the drive unit 1, receives linear driving force and transmits power;
[0035] The conversion mechanism 3 is connected to the transmission assembly 2 and converts linear motion into rotational or translational motion.
[0036] The protective component 4 is connected to the conversion mechanism 3 and automatically opens and closes under the drive of the conversion mechanism 3 to cover the camera lens.
[0037] In one specific embodiment, one end of the conversion mechanism 3 is connected to the transmission assembly 2, and the other end is connected to the protective component 4; the transmission assembly 2 receives the linear driving force from the drive unit 1 and transmits it to the conversion mechanism 3, driving the protective component 4 to perform rotational or translational movements.
[0038] In one specific embodiment, the drive unit 1 includes any one of an electric push rod, a cylinder, or a linear motor, and outputs linear driving force through electrical energy, pneumatic energy, or mechanical energy.
[0039] In a preferred embodiment, the drive unit 1 is an electric actuator that outputs linear driving force via electrical energy. The extension rod 5 of the electric actuator is positioned towards the camera lens to facilitate connection to the subsequent transmission mechanism.
[0040] In one specific embodiment, the transmission component 2 includes any one of a slider, a guide rail, and a rack, configured to cooperate with an external fixed bracket to form a linear motion guiding structure.
[0041] In a preferred embodiment, the transmission component 2 is a slider.
[0042] In one specific embodiment, the conversion mechanism 3 includes any one of a linkage group, a gear group, or a cam mechanism, used to convert linear motion into rotational or translational motion.
[0043] In a preferred embodiment, the conversion mechanism 3 is a linkage group, including at least two linkages to form a four-bar linkage mechanism, so as to improve motion stability and opening and closing accuracy; the linkages include a first linkage and a second linkage.
[0044] In one specific embodiment, the protective component 4 is mounted in front of the camera lens via a revolute joint or a sliding joint. A revolute joint is a shaft-like component in a mechanical structure used to support rotational motion, allowing connected objects to rotate around its axis; it is commonly found in hinges, pivots, pins, and other structures.
[0045] In a preferred embodiment, the protective component 4 is a protective cover, including a first protective cover and a second protective cover, which are symmetrically installed on both sides of the camera lens via a rotating joint. The other end of the conversion mechanism 3 is connected to the rotating joint for transmission, driving the protective cover to rotate around the rotating joint to open and close.
[0046] In one specific embodiment, the edge of the protective component 4 is provided with a sealing structure to enhance its dustproof and waterproof performance in the closed state.
[0047] In one specific embodiment, the sealing structure includes any one of an elastic seal, a magnetic seal, or a labyrinth seal.
[0048] In a preferred embodiment, the sealing structure is an elastic seal, specifically a sealing strip, to enhance dust and water resistance when closed. The sealing strip is made of soft silicone material with a D-shaped cross-section, enabling it to form a tight seal with the surface around the lens when the protective cover is closed, effectively preventing dust and moisture from entering the lens.
[0049] The extension and retraction of the electric actuator is converted into the rotational motion of the protective cover via a slider and connecting rod assembly, thus achieving automatic opening and closing of the protective cover. When the electric actuator extends, it pushes the slider forward along the guide groove. The slider drives the first connecting rod forward, and the first connecting rod transmits force and motion through its hinge point with the second connecting rod, causing the second connecting rod to rotate around the fixed hinge point. This, in turn, causes the protective cover connected to the other end of the second connecting rod to rotate around a pivot, thus opening the protective cover. When the electric actuator retracts, the slider moves backward under the pulling force of the electric actuator. Through the transmission of the conversion mechanism, the protective cover rotates in the opposite direction around the pivot, thus closing the protective cover.
[0050] With the protective cover fully closed, the sealing strip adheres tightly to the surface around the lens, creating a seal that effectively prevents dust and moisture from entering the lens. With the protective cover fully open, the angle between the cover and the lens optical axis is 90 degrees, ensuring it does not obstruct or affect normal camera operation.
[0051] This utility model provides an automatic opening and closing mechanism for a camera protection device. This mechanism effectively prevents water stains from remaining on the lens, ensuring image clarity and directly improving the success rate of barcode scanning. It is particularly suitable for harsh environments with high cleanliness requirements. The integrated design using a single electric actuator replaces the traditional cylinder solution, eliminating the need for a complex pneumatic system, simplifying the structure, and reducing maintenance costs and complexity. The modular and compatible design enhances the system's versatility, allowing the electric actuator to be replaced with a small cylinder, flexibly adapting to different equipment needs and expanding the product's applicability.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
