[0027] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0028] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0029] like Figure 1 and Figure 2 As shown, a digital camera lens protective case of this application includes an outer shell 1, an inner liner 2, a rotating opening and closing mechanism 3, a damping component 4, a connecting hinge 5, and a toothed sleeve structure 6. These components work together to achieve the safety protection function for the digital camera lens.

[0030] The outer shell 1 of the protective case consists of a pair of petal-shaped shells that can be detachably connected via a plug. The petal-shaped shells are designed in a semi-cylindrical shape, covering the periphery of the digital camera lens to form a complete protective enclosure. Each petal-shaped shell has a corresponding socket or post, which can be inserted and locked together during assembly. For example, one petal-shaped shell has a protruding post at its edge, while the corresponding part of the other petal-shaped shell has a recessed socket; the two are connected and separated by a plug-and-play mechanism.

[0031] The inner liner 2 is a soft material component used to provide cushioning and prevent scratches at the contact points with the lens. It is specifically installed on the inner wall surface of each flap shell, ensuring a connection with the outer hard shell while directly facing the digital camera lens. The inner liner 2 can be made of foam, rubber, or fabric, and can be fixed by adhesive or press-fitting to the inner wall surface of the outer shell 1, ensuring its stability during use.

[0032] The rotating opening and closing mechanism 3 is a key device located at the junction of the two valve shells, responsible for controlling the opening and closing of the pair of valve shells of the outer shell 1. The main body of this mechanism consists of an annular groove 31, located on the outer surface of one of the valve shells, and a flexible buckle 32 is installed within it to secure the overall closed state of the outer shell. In actual implementation, the annular groove 31 can be formed into a specific shape on the surface of the shell through precision injection molding, while the buckle is made of a material with a certain degree of elastic deformation, such as plastic or spring steel, and is pre-installed into the annular groove 31 during assembly.

[0033] The damping component 4 is an independent functional component surrounding the rotary opening and closing mechanism 3. It is specifically embedded within the aforementioned annular groove 31 and fixed in place by positioning ribs. The main function of this component is to increase the stable resistance required during rotation and prevent loosening. The damping component 4 is typically made of a polymer composite material, which generates friction to resist the tendency to move when rotated under applied force. The specific installation method involves pre-reserving multiple protruding structures (i.e., positioning ribs) during the manufacturing process of the damping component 4, inserting them into specific slots in the annular groove 31 to firmly confine it within a designated range, ensuring normal operation is not affected.

[0034] The connecting hinge 5 is a component fixed to the outside of one of the flaps of the outer casing 1 and used in conjunction with other related parts, such as the rotating opening and closing mechanism 3. The hinge typically comprises two pivot-type connecting plates, each fixed to the side of one flap by welding or screws. Furthermore, it is connected to other moving parts via pins to support the smoothness and reliability of the opening action. This connection allows the entire device to open and close flexibly when needed and remain tightly closed.

[0035] The gear sleeve structure 6, as a key component for further optimizing damping adjustment performance, is arranged around the outer area of ​​the damping element 4 and features an eccentric design. This part achieves layered variations in resistance levels by precisely calculating and adjusting the distance difference between its corresponding part and the inner core. The specific construction approach involves first machining it to standard dimensions based on the center offset parameters, then hot-pressing it into the appropriate location using a mold. This allows for selective enhancement of torque output within a specific range to meet the user's operational requirements in different situations.

[0036] Regarding the technical challenge of preventing accidental loosening, this solution employs a multi-layered anti-loosening measure to ensure overall stability. The first layer utilizes damping component 4, providing a basic rotational resistance mechanism. Secondly, a flexible snap-lock design ensures that once the outer shell is closed, it is difficult for it to detach due to slight vibrations. Finally, an eccentric toothed sleeve structure 6 is introduced for refined damping force distribution, further enhancing system reliability. All these elements are closely interconnected and complementary, ultimately successfully resolving the issue of accidental opening common in traditional structures, thus providing users with a safer and more convenient user experience.

[0037] like Figure 4 As shown, in one embodiment, the damping component 4 of a digital camera lens protective housing of this application employs a special design to enhance overall functionality. The damping component 4 is installed inside the annular groove 31 on the outer shell 1 and achieves precise nesting through raised positioning ribs 33. To increase its stability and contact effect during use, the damping component 4 is made of elastic rubber material. This material possesses excellent elasticity and durability, making it suitable as a key component of the protective housing. Structurally, the inner wall of the damping component 4 is provided with multiple annular textures 41. These textures are evenly distributed and tightly adhere to the inner wall of the annular groove 31, significantly enhancing friction and resistance performance, further optimizing the damping effect, and preventing accidental loosening.

[0038] For example, the aforementioned characteristics can be achieved through specific manufacturing and assembly processes. For instance, after the damping component 4 is injection molded, its elastic properties allow it to snap into the annular groove 31 in the outer casing 1, ensuring that its annular texture 41 completely conforms to the groove surface. Furthermore, when assembling the gear sleeve structure 6, the damping component 4 needs to be eccentrically fitted to the component to adjust for different damping levels required during rotation. Thus, a stable connection and fit is formed between the components.

[0039] like Figure 4As shown, in one embodiment, a flexible snap-fit ​​32 of a digital camera lens protective housing of this application is connected at one end to a rotating opening and closing mechanism 3, and the other end is embedded in an arc-shaped groove 11 on the housing body 1. This position and connection form effectively limit the maximum rotation angle. The housing body 1 consists of a pair of flaps connected by insert rods, covering and fixing to the outside of the digital camera lens. The rotating opening and closing mechanism 3 is mounted on the surface of the housing body 1, and through interaction with the flexible snap-fit ​​32, maintains a stable locking state while ensuring flexible opening and closing. The arc-shaped groove 11 is set in a specific area on the surface of the housing body 1, and in combination with the flexible snap-fit ​​32, it limits the movement of the structure.

[0040] For example, the flexible buckle 32 can be designed as a strip-shaped component with a certain degree of elasticity, with one end fixedly welded or integrally formed on the rotating opening and closing mechanism 3, while the other end extends to a range that can accurately embed into the arc-shaped groove 11. Specifically, the length and position of the arc-shaped groove 11 can be determined according to the requirement of the maximum rotation angle to ensure that when the opening and closing mechanism rotates to the preset position, the flexible buckle 32 just contacts the end point of the arc-shaped groove 11, preventing it from exceeding the safe rotation range.

[0041] like Figure 7 As shown, in one embodiment, the connecting hinge 5 of a digital camera lens protective housing of this application includes a limiting block 51, which is used to set a physical constraint on the minimum rotation angle of the rotating opening and closing mechanism 3 relative to the outer shell 1. This structure ensures that functional failure or damage caused by excessive rotation angle can be effectively avoided during the opening and closing operation of the lens protective housing. A connecting hinge 5 is provided on the outer side of one shell segment of the outer shell 1, and a rotational connection is established with the rotating opening and closing mechanism 3 through this hinge. The limiting block 51 is installed in a key force-bearing part inside the connecting hinge 5, and its structural shape is customized according to design requirements, such as in the form of a rectangular protrusion or an arc-shaped blocking piece.

[0042] Specifically, the limiting block 51 is fixedly connected to one fixed end of the connecting hinge 5, and forms a spatial blocking effect with the other side during rotation. For example, one side of the rotating shaft in the connecting hinge 5 can be designed with a recessed structure, and the limiting block 51 is embedded in this recess, allowing it to move relative to the hinge only within a preset range. In this way, when the rotating opening and closing mechanism 3 rotates to the angular limit position defined by the limiting block 51, the continued rotation of the hinge is restricted, thereby maintaining the overall structure in a reliable working state. The components are mainly assembled using assembly processes or simple bonding to ensure precise fit between parts.

[0043] like Figure 3As shown in one embodiment, a digital camera lens protective housing of this application is characterized in that the inner liner 2 is provided with a positioning post 21 for fixed installation with the outer shell 1. The positioning post 21 is a protruding structure, specifically designed to ensure that the inner liner 2 can be precisely and securely fitted into a pre-set hole in the outer shell 1. This connection method achieves fixation through physical insertion, avoiding the use of adhesives or screws, which facilitates disassembly and maintenance while maintaining assembly accuracy and reliability. Since the inner liner 2 typically comes into direct contact with the lens, its installation stability is crucial to ensuring that the digital camera lens is not scratched.

[0044] From a structural perspective, the shape of the positioning post 21 matches the hole on the outer shell 1, and the gap between them is precisely designed to prevent loosening or displacement. Furthermore, to accommodate different assembly processes or material choices, the positioning post 21 may be further provided with a tapered guide portion or other chamfered form for easy and quick insertion and to improve fault tolerance. Specifically, the corresponding hole on the outer shell 1 is located inside the flap shell near the edge of the lens area to facilitate alignment with the functional area of ​​the inner liner 2.

[0045] For example, during the manufacturing process of the outer shell 1, a circular or polygonal hole of suitable size is first pre-drilled. Then, the inner liner 2 with positioning posts 21 is pressed into the hole until the two are fully fitted. The positioning posts 21 may contain flexible materials or a slightly interference fit design to ensure connection strength. The entire process achieves a secure assembly without the need for additional connectors and is also compatible with various production environments and requirements.

[0046] like Figure 4 and Figure 5 As shown, in one embodiment, the rotating opening and closing mechanism 3 of a digital camera lens protective housing according to this application includes an auxiliary pressure plate 34. Its structure is designed to press the damping member 4 tightly within the annular groove 31, preventing displacement or loosening due to external force or long-term use. The auxiliary pressure plate 34 is positioned close to the damping member 4 and cooperates with the annular groove 31 to achieve a stabilizing effect. This structure improves connection stability by adding an extra layer of restraint, preventing malfunctions during use of the rotating opening and closing mechanism 3.

[0047] Specifically, the auxiliary pressure plate 34 is typically fixed to the inner wall of the annular groove 31, for example, through bonding, interference fit, or mechanical locking to achieve a tight fixation. The damping component 4 relies on its own protruding positioning ribs 33 to engage in the annular groove 31, and the auxiliary pressure plate 34 further applies force to achieve stable nesting. The entire assembly process can be ensured by pre-setting the tolerances and material hardness between components. In addition, the design of the auxiliary pressure plate 34 also takes into account the spatial coordination with other components, such as ensuring that it does not obstruct the normal function of the flexible buckle 32, while also retaining a certain degree of maintainability and removability.

[0048] like Figure 7 As shown, in one embodiment, the connecting hinge 5 of a digital camera lens protective shell of this application enhances its durability through a special structural design. The connecting hinge 5 is located on the outer side of one shell segment of the outer shell 1 and is rotatably connected to the rotating opening and closing mechanism 3, enabling the movable opening and closing function between the two shell segments of the outer shell 1. To increase the service life of the connecting hinge 5, a wear-resistant coating 52 is added to the surface of the hinge shaft of the connecting hinge 5. This wear-resistant coating 52 tightly covers the surface of the hinge shaft, reducing friction and preventing surface damage. This design effectively extends the overall lifespan of the connecting hinge 5, thereby ensuring the reliability and stability of the protective shell under long-term use.

[0049] Specifically, suitable wear-resistant materials can be selected to treat the surface of the hinge shaft, such as hard ceramic coatings or special alloy coatings. These materials can significantly improve the wear resistance of the hinge shaft without changing its original structure and dimensions. In addition, the coating can be uniformly adhered to the surface of the hinge shaft by methods such as electroplating, spraying, or sintering, ensuring its long-lasting durability in repeated opening and closing movements.

[0050] like Figure 6 As shown, in one embodiment, the rotary opening and closing mechanism 3 includes a flexible latch 32 for locking the position of the rotary opening and closing mechanism 3. To reduce wear and tear on the flexible latch 32 that may be caused by long-term use, a flexible silicone sleeve 321 is added to completely cover its outer surface. This sleeve not only has high elasticity and wear resistance, but also forms an effective protective layer by tightly fitting the external structure of the flexible latch 32.

[0051] For example, the flexible silicone sleeve 321 can be installed by injection molding in conjunction with the flexible buckle 32, directly covering its outer surface without affecting the overall operation of the rotating opening and closing mechanism 3. Further explanation of its structural connection reveals that the flexible buckle 32 is located on the inner wall of the annular groove 31 and rotates synchronously with the mechanism. The silicone sleeve, as a protective layer, is embedded in this outer area, while maintaining sufficient thickness to absorb friction during daily use, thereby extending the overall service life.

[0052] Specifically, the flexible silicone sleeve 321 can be integrally molded onto the outside of the flexible buckle 32 using a dual-material injection molding method. This method ensures a secure connection between the two and allows for precise control over their relative position and dimensional fit to meet actual assembly needs and functional requirements.

[0053] In actual operation, when this device is in use, a digital camera lens can be placed inside the housing 1, and then the pair of flaps can be closed and locked using the rotating opening and closing mechanism 3. The inner liner 2 contacts the lens to provide cushioning protection and prevent scratches. The rotating opening and closing mechanism 3 is adjusted to the appropriate locking position by rotating the connecting hinge 5. During this process, the damping element 4 provides stable resistance to prevent the mechanism from accidentally loosening, and the raised positioning rib 33 ensures the stable installation of the damping element 4. In addition, the eccentrically set toothed sleeve structure 6 can adjust the damping force at different rotation angles as needed when the rotating opening and closing mechanism 3 is working, thereby ensuring the safety and convenience of the housing 1 in the closed state.

[0054] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
