The eyepiece cup can not only effectively block external light interference, but also help the photographer observe the shooting picture more clearly and improve the shooting quality.

[0003] In related technologies, there are mainly two installation methods for the eyepiece cup. The first method is to use the step difference at the viewfinder opening of the camera for snap installation, which requires the viewfinder opening position of the camera itself to have steps or reserved positions. The second method is to install through the hot shoe slot on the top of the camera, and fix the eyepiece cup at the viewfinder opening of the camera.

[0004] However, the installation methods in related technologies rely on the steps, positions or hot shoe slots of the camera viewfinder opening. Summary of the Utility Model

[0005] The main object of the utility model is to propose a light-shielding component of a viewfinder, aiming to solve the problems that the installation of the existing light-shielding component of the viewfinder depends on the steps or positions of the viewfinder opening and occupies the hot shoe.

[0006] To achieve the above object, the utility model proposes a light-shielding component of a viewfinder, which includes:

[0007] A light-shielding cover, which forms a first hollow inner hole;

[0008] An installation bracket, which includes a connecting frame, an extension arm and a clamping plate. The connecting frame forms a second hollow inner hole. The connecting frame is detachably connected to the light-shielding cover and is used to abut against the first side of the camera and make the second hollow inner hole communicate the viewfinder opening of the camera with the first hollow inner hole. One end of the extension arm is connected to the connecting frame and is used to abut against the second side of the camera adjacent to the first side. The clamping plate is bent and arranged at the other end of the extension arm and is arranged opposite to the connecting frame at an interval. The clamping plate is used to abut against the third side of the camera adjacent to the second side and opposite to the first side at an interval.

[0011] The inner wall of the first hollow inner hole of the light-shielding cover is configured with a second mounting portion, and the second mounting portion cooperates with the first mounting portion to relatively fix the light-shielding cover to the connection frame.

[0012] In some embodiments, the first mounting portion is an annular card slot formed along the circumferential side of the connection frame, and the second mounting portion is an annular flange formed along one end of the light-shielding cover, and the annular flange is clamped in the annular card slot.

[0013] In some embodiments, the buckle plate is arranged parallel or approximately parallel to the connection frame, and the buckle plate is used to abut against the third side of the camera that is adjacent to the second side and spaced relative to the first side.

[0014] In some embodiments, a soft rubber pad is provided on the surface of the buckle plate facing the connection frame, and the soft rubber pad is used to contact the third side of the camera that is adjacent to the second side and spaced relative to the first side when the mounting bracket is mounted on the camera.

[0015] In some embodiments, a groove is configured on the surface of the buckle plate facing the connection frame, the soft rubber pad is arranged in the groove, and at least part of the end of the soft rubber pad facing the connection frame is exposed outside the notch of the groove.

[0016] In some embodiments, the connection frame, the extension arm and the buckle plate are integrally formed.

[0017] And / or, the light-shielding cover is a cover body made of a flexible material.

[0018] In some embodiments, the light-shielding component of the viewfinder further includes a connecting rope, and one end of the connecting rope is connected to the extension arm or the connection frame.

[0019] The present utility model further provides a photographic device, including a camera and the light-shielding component of the viewfinder in the foregoing embodiments. When the light-shielding component of the viewfinder is mounted on the camera, the connection frame of the light-shielding component of the viewfinder is directly opposite to the viewfinder opening of the camera.

[0020] In the technical solution of the present utility model, the light-shielding cover communicates with the viewfinder opening of the camera through a connecting frame, forming an effective light-shielding effect to avoid the interference of ambient light.

[0032] In modern photography, the camera viewfinder is an important tool for photographers to compose pictures and adjust shooting parameters. However, in outdoor or strong light environments, ambient light may affect the visibility of the viewfinder and reduce shooting accuracy. Therefore, the viewfinder usually needs to be equipped with a lens hood to block excess light and improve the clarity and comfort of viewing. The lens hood can not only improve the user experience but also effectively protect the optical elements inside the viewfinder. For the specific installation method of the lens hood, please refer to Figure 1 and Figure 2 , Figure 1 which is the assembly schematic diagram of the light-shielding component of the viewfinder and the camera in an embodiment of the present utility model, Figure 2 which is the structural schematic diagram of the light-shielding component of the viewfinder in an embodiment of the present utility model.

[0033] The present utility model provides a light-shielding component for a viewfinder, and the light-shielding component of the viewfinder includes:

[0034] A lens hood 100, and the lens hood 100 is formed with a first hollow inner hole 101;

[0035] Mounting bracket 200, the mounting bracket 200 includes a connecting frame 201, an extension arm 204 and a buckle plate 205. The connecting frame 201 is formed with a second hollow inner hole 202. The connecting frame 201 is connected to the light shield 100 and is used to abut against the first side portion 301 of the camera 300 and communicate the second hollow inner hole 202 with the viewfinder opening 304 of the camera 300 and the first hollow inner hole 101. One end of the extension arm 204 is connected to the connecting frame 201. The buckle plate 205 is provided at the other end of the extension arm 204 and is disposed opposite to the connecting frame 201 at an interval. The buckle plate 205 and the connecting frame 201 are used to jointly clamp the camera 300.

[0036] In this embodiment, the main function of the light shield 100 is to block the interference of ambient light and provide a clearer view for the photographer. The light shield 100 can adopt an ergonomic shape design to make it fit the facial contour better and improve the wearing comfort. For example, the light shield 100 can adopt a concave design. Specifically, the inner side of the light shield 100 adopts a concave design to fit the facial contour and ensure a comfortable wearing feeling. Of course, it can also be designed into a U-shaped or C-shaped design. Such shapes can provide good support when the light shield 100 fits the face and do not block the view at the same time.

[0037] To increase the wearing comfort, some softer edges can be adopted. For example, the edge adopts a soft arc design, which can reduce the friction with the facial skin and increase the wearing comfort. It can also be to make the edge transition naturally to fit different facial shapes.

[0038] In terms of materials, soft and durable silicone or rubber can be selected. These materials can not only provide a soft touch but also effectively reduce the pressure on the skin during long-term use.

[0039] The function of the mounting bracket 200 is to stably mount the light shield 100 on the camera 300, avoiding occupying the hot shoe slot of the camera 300 or relying on the raised step at the viewfinder opening 304 of the camera 300. The shape of the mounting bracket 200 can be conventionally set as a rectangular frame for easy fixed connection with the light shield 100 and the camera 300. It can also be set with an "L"-shaped extension arm 204. Specifically, it extends outward from the frame and closely fits the side of the camera 300 during installation.

[0040] In addition, to reduce the overall weight of the camera 300, the mounting bracket 200 needs to consider lightweight design. That is to say, hollow parts can be designed on the extension arm 204 to reduce the weight while maintaining sufficient strength. Specifically, it can be set as a honeycomb structure. The honeycomb structure can enhance the strength and stability of the material and reduce the weight at the same time to ensure stable support without affecting other functions of the camera 300. Its material can be selected as a lightweight and strong alloy or engineering plastic to ensure strength and durability while reducing the burden on the camera 300.

[0041] In the mounting bracket 200 of the light-shielding component, the connecting frame 201, the extension arm 204, and the fastening plate 205 each play a key role in ensuring the stable installation of the light-shielding cover 100 and the convenience of use.

[0042] The connecting frame 201 is the core component of the mounting bracket 200 and is used to firmly connect the light-shielding cover 100 to the camera 300. It is usually docked with the hollow inner hole of the light-shielding cover 100 and fixed around the viewfinder of the camera 300. The connecting frame 201 forms a hollow channel, enabling the viewfinder opening 304 of the camera 300 to communicate with the first hollow inner hole 101 of the light-shielding cover 100, ensuring unobstructed transmission of the line of sight. And it provides the basic structure of the overall bracket, ensuring that the mounting bracket 200 remains stable on the camera 300 without shaking.

[0043] The extension arm 204 extends from the connecting frame 201 and is used to support and stabilize the mounting bracket 200. It usually abuts against the side of the camera 300, increasing the stability of the bracket. By abutting against the second side portion 302 of the camera 300, the extension arm 204 helps to position the bracket and can prevent the bracket from shifting during use.

[0044] In addition, the extension arm 204 can distribute the weight of the mounting frame and the pressure of the light-shielding cover 100 to multiple parts of the camera 300, reducing the pressure on a single part and improving the installation reliability.

[0045] The fastening plate 205 is used to fix the mounting bracket 200 on the other side of the camera 300. By closely adhering to the third side portion 303 of the back of the camera 300, it ensures that the bracket is not easily detached.

[0046] Overall, the light-shielding cover 100 of the viewfinder is designed to be quickly snapped on and removed, making the installation and removal process simple and fast, and convenient for users to operate. These three components work together to enable the light-shielding component to be stably and conveniently installed on the camera 300 while maintaining a good light-shielding effect and user experience.

[0047] In actual use, the mounting bracket 200 can be fixedly connected to the camera 300 through simple operations, and the light-shielding cover 100 can be quickly loaded and unloaded through the design of the mounting bracket 200.

[0048] Specifically, the bottom hollow inner hole of the lens hood 100 is docked with the second hollow inner hole 202 of the connection frame 201 to ensure a tight connection between the lens hood 100 and the connection frame 201. The function of the connection frame 201 is to firmly fix the lens hood 100 on the camera 300. Its hollow inner hole is aligned with the viewfinder opening 304 of the camera 300, enabling the photographer to clearly observe through the lens hood 100. During the installation process, the photographer can adjust the position of the connection frame 201 so that its periphery fits around the viewfinder of the camera 300 to ensure unobstructed vision. One end of the connection frame 201 is connected to the extension arm 204. The photographer pushes the extension arm 204 towards the second side 302 of the camera 300, causing the extension arm 204 to abut against the second side 302 of the camera 300, that is, the side adjacent to the viewfinder. The function of the extension arm 204 is to provide additional support to prevent the light-shielding component from moving during use. At the same time, the buckle plate 205 at the other end of the extension arm 204 abuts against the third side 303. The buckle plate 205 is buckled on the back of the camera 300 to ensure the stability of the entire light-shielding component and prevent it from sliding during shooting. The entire process does not require tools, and the photographer can complete the installation or disassembly within a few seconds. If the photographer needs to replace the lens hood 100 with another model, they only need to remove the connection frame 201 from the lens hood 100 to perform the replacement.

[0049] In the technical solution of the present utility model, the lens hood 100 communicates with the viewfinder opening 304 of the camera 300 through the connection frame 201 to form an effective light-shielding effect and avoid interference from ambient light. The design of the extension arm 204 enhances the stability of the mounting bracket 200, facilitating it to closely fit multiple sides of the camera 300 without occupying the hot shoe slot and ensuring that other functions of the camera 300 are not affected. The buckle plate 205 provides a fixing force through close contact with the adjacent side of the back of the camera 300, guaranteeing the stability of the entire light-shielding component during use. In this way, the installation of the lens hood 100 no longer depends on the steps or reserved positions of the viewfinder opening 304 of the camera 300, but is detachably connected to the mounting bracket 200, and then the mounting bracket 200 is detachably connected to the camera 300. Even if there are no steps or positions at the viewfinder opening 304 of the camera 300, the lens hood 100 can still be stably installed on the camera 300.

[0050] In some embodiments, the connection frame 201 is detachably connected to the lens hood 100; the detachable connection between the connection frame 201 and the lens hood 100 enables the user to quickly load, unload, and replace the lens hood 100 during use.

[0051] Continue to refer to Figure 2 , in this embodiment, at least one side of the connection frame 201 is connected to one end of the extension arm 204, and the connection frame 201 is disposed perpendicular or inclined relative to the extension arm 204. The outer sidewall of the connection frame 201 is configured with a first mounting portion 203;

[0052] The inner wall of the first hollow inner hole 101 of the light shield 100 is configured with a second mounting portion 102, and the second mounting portion 102 cooperates with the first mounting portion 203 to relatively fix the light shield 100 to the connection frame 201.

[0053] In this embodiment, at least one side of the connection frame 201 is connected to one end of the extension arm 204. The connection frame 201 can be vertically or obliquely arranged relative to the extension arm 204 to meet the installation requirements of different cameras 300. A first mounting portion 203 is configured on the outer side wall of the connection frame 201, and this mounting portion is used to cooperate with the second mounting portion 102 of the light shield 100, so that the light shield 100 can be stably fixed on the connection frame 201.

[0054] In this embodiment, the design of the connection frame 201 fully considers the tight connection with the light shield 100 to ensure the stability and convenience of use of the light shielding assembly. The first mounting portion 203 of the connection frame 201 and the second mounting portion 102 of the light shield 100 can adopt various cooperation methods to adapt to different usage scenarios and design requirements.

[0055] For example, threaded connection can be adopted. Specifically, threads can be provided on the outer side wall of the connection frame 201 as the first mounting portion 203, and internal threads that cooperate with them are provided on the inner wall of the light shield 100. This method provides stronger fixing force, is suitable for scenarios that require more stable installation, and can be achieved only by rotation during disassembly.

[0056] Of course, when considering the need for quick disassembly, magnetic adsorption can be used as the installation method. Specifically, the first mounting portion 203 of the connection frame 201 can be embedded with magnetic materials, and the second mounting portion 102 of the light shield 100 contains corresponding metal materials, realizing quick connection and disassembly through magnetic force, which is suitable for the need to quickly replace the light shield 100.

[0057] In some embodiments, the first mounting portion 203 can be an elastic buckle, and corresponding grooves 205a or holes are provided on the inner wall of the light shield 100. Through pressing for installation, the buckle automatically snaps into the groove 205a to achieve a firm installation effect, and at the same time it is convenient for users to quickly replace.

[0058] This embodiment provides a flexible and stable connection method between the light shield 100 and the connection frame 201, and users can select different combinations of mounting portions according to actual needs. The diverse installation methods not only improve the applicability of the light shielding assembly, but also enhance the user's operation experience and meet the usage requirements in different environments.

[0059] Continue to refer to Figure 2, in this embodiment, the first mounting portion 203 is an annular card slot formed along the peripheral side of the connecting frame 201, and the second mounting portion 102 is an annular flange formed along one end of the light-shielding cover 100. The annular flange is clamped in the annular card slot.

[0060] In this embodiment, preferably, the first mounting portion 203 of the connecting frame 201 is set as an annular card slot, while the second mounting portion 102 of the light-shielding cover 100 is designed as a matching annular flange. By embedding the flange of the light-shielding cover 100 into the card slot, quick installation and firm fixation are achieved, ensuring that the light-shielding cover 100 is not easily detached during use. In this way, the combination of the annular card slot and the annular flange provides a simple and effective installation method.

[0061] Continue to refer to Figure 2 , in this embodiment, the buckle plate 205 is arranged relatively parallel or approximately parallel to the connecting frame 201. The buckle plate 205 is used to abut against the third side portion 303 of the camera 300 that is adjacent to the second side portion 302 and spaced opposite to the first side portion 301.

[0062] In this embodiment, the buckle plate 205 is arranged relatively parallel to the connecting frame 201, and its design purpose is to provide a stable support and fixation for the camera 300. The buckle plate 205 ensures the stability of the light-shielding component after installation through close contact with the third side portion 303 of the camera 300, and will not shake or displace during use.

[0063] Specifically, the buckle plate 205 is arranged parallel to the connecting frame 201, so that the entire mounting bracket 200 forms a stable structure to adapt to the third side portion 303 of the camera 300. Among them, the buckle plate 205 can be made of a strong material, such as high-strength plastic or light metal, to ensure that it will not deform or be damaged during long-term use.

[0064] During the installation process, the user abuts the connecting frame 201 of the light-shielding cover 100 against the first side portion 301 of the camera 300 to align it with the viewfinder 304 of the camera 300. At this time, the extension arm 204 will unfold along the second side portion 302 of the camera 300 to provide additional support. Subsequently, the buckle plate 205 abuts against the third side portion 303 of the camera 300 through a simple operation, forming a complete wrapping and fixation of the three side portions of the camera 300 to ensure the stability of the component.

[0065] Due to the parallel arrangement of the buckle plate 205 and the connecting frame 201, the user only needs to apply a slight force to move the buckle plate 205 away from the third side portion 303 of the camera 300 for disassembly or replacement.

[0066] Through the parallel design of the buckle plate 205 and the connection frame 201, the present embodiment achieves effective light shielding for the viewfinder of the camera 300 and ensures the stable installation of the light shielding component. The abutment of the buckle plate 205 against the third side portion 303 of the camera 300 provides additional stability and prevents the component from shifting during shooting.

[0067] Refer to Figures 2 to 4 , Figure 2 which is a schematic structural view of the light shielding component of the viewfinder in an embodiment of the present utility model, Figure 3 which is a front view of the light shielding component of the viewfinder in an embodiment of the present utility model, Figure 4 and is a sectional view taken along A-A.

[0068] In the present embodiment, a soft rubber pad 205b is provided on the surface of the buckle plate 205 facing the connection frame 201. The soft rubber pad 205b is used to contact the third side portion 303 which is adjacent to the second side portion 302 and spaced opposite to the first side portion 301 when the mounting bracket 200 is mounted on the camera 300.

[0069] In the present embodiment, the design of the buckle plate 205 and the connection frame 201 is further optimized to improve the stability and protection of the mounting bracket 200 on the camera 300. Specifically, a soft rubber pad 205b is provided on the surface of the buckle plate 205 facing the connection frame 201, and the soft rubber pad 205b directly contacts the third side portion 303 of the camera 300 during the installation process.

[0070] A soft and highly friction soft rubber pad 205b is provided on the surface of the buckle plate 205 facing the connection frame 201. The soft rubber pad 205b is used to closely contact the third side portion 303 of the camera 300 when the mounting bracket 200 is mounted on the camera 300. Among them, the soft rubber pad 205b can be made of wear-resistant and anti-aging materials, such as silicone or polyurethane, to ensure good performance during long-term use.

[0071] During the installation process, the user abuts the connection frame 201 against the first side portion 301 of the camera 300 to align it with the viewfinder opening 304 of the camera 300, and at the same time unfolds the extension arm 204 along the second side portion 302. During the installation of the buckle plate 205, the soft rubber pad 205b fits with the third side portion 303 of the camera 300. Through the flexibility and friction of the soft rubber pad 205b, the stability of the mounting bracket 200 can be further enhanced.

[0072] And the soft rubber pad 205b can absorb the tiny vibrations generated during the installation process, protect the outer shell of the camera 300 from abrasion, and ensure the stability of the light shielding component during use. At the same time, due to the soft characteristics of the soft rubber pad 205b, it can effectively prevent the buckle plate 205 from scratching or damaging the surface of the camera 300 during the installation and disassembly processes.

[0073] By providing a soft rubber pad 205b on the buckle plate 205, the present embodiment improves the installation stability of the light-shielding component and the protection ability of the camera 300. The application of the soft rubber pad 205b not only enhances the friction between the bracket and the camera 300, improving the stability of the component, but also provides a certain degree of protection for the housing of the camera 300.

[0074] Continuing to refer to Figure 2 , in the present embodiment, a groove 205a is formed on the surface of the buckle plate 205 facing the connection frame 201, the soft rubber pad 205b is disposed in the groove 205a, and at least a part of the end of the soft rubber pad 205b facing the connection frame 201 is exposed outside the notch of the groove 205a.

[0075] In the present embodiment, the design of the buckle plate 205 realizes a more stable and protective installation effect by forming a groove 205a on the surface facing the connection frame 201 and providing a soft rubber pad 205b in the groove 205a. The design of the partial exposure of the soft rubber pad 205b ensures good contact with the camera 300 and installation stability.

[0076] Specifically, a groove 205a is specially designed on the surface of the buckle plate 205 facing the connection frame 201 for accommodating the soft rubber pad 205b. The size of the groove 205a is larger than the outer circumference of the soft rubber pad 205b, and the depth of the groove 205a is less than the height of the software pad to ensure that the soft rubber pad 205b can be effectively embedded therein. The groove 205a provides a fixing effect on the soft rubber pad 205b, so that the soft rubber pad 205b remains in the correct position during use and is not easily detached or moved.

[0077] The soft rubber pad 205b is installed in the groove 205a, and at least a part of the end facing the connection frame 201 is exposed outside the notch of the groove 205a. Through this design, the soft rubber pad 205b can provide good friction and buffering effects when contacting the third side portion 303 of the camera 300.

[0078] By providing a groove 205a in the buckle plate 205 and embedding the soft rubber pad 205b, the present embodiment effectively improves the installation stability and use safety of the light-shielding component.

[0079] Refer to Figure 2 , in the present embodiment, the connection frame 201, the extension arm 204, and the buckle plate 205 are integrally formed;

[0080] And / or, the light-shielding cover 100 is a cover body made of a flexible material.

Through the integral forming process, the connection parts between components can be reduced, improving the overall durability and stability.

[0082] Among them, the connecting frame 201, the extension arm 204, and the buckle plate 205 adopt an integrally formed design, which can be realized by a variety of manufacturing processes. Specifically, injection molding can be used. For example, plastic particles are heated and melted and then injected into a mold, and an integrated structure is formed through cooling and solidification. It is applicable to a variety of thermoplastic plastics, such as ABS, polycarbonate, nylon, etc. Injection molding has a fast production speed, is suitable for mass production, and has a low manufacturing cost.

[0083] Additive manufacturing can also be used, that is, the so-called 3D printing. Specifically, it mainly constructs three-dimensional objects by stacking materials layer by layer, and is suitable for small-batch production and the manufacturing of complex shapes. Applicable materials include plastics (PLA, ABS), metals (titanium alloy, stainless steel), resins, etc. This process has flexible design, does not require mold opening, and is suitable for rapid prototyping and customized production.

[0084] In this embodiment, the light-shielding cover 100 can be made of a flexible material, and its design purpose is to provide a comfortable use experience and an effective light-shielding effect.

[0088] In this embodiment, the light-shielding cover 100 of the viewfinder further includes a connecting rope to further improve the safety and use convenience of the component. One end of the connecting rope is fixedly connected to the extension arm 204 or the connecting frame 201 to ensure that the light-shielding cover 100 will not be lost when the light-shielding cover 100 accidentally falls off or needs to be temporarily removed during the shooting process.

[0089] The connecting rope can be made of materials with high flexible strength, such as nylon or braided wire, to ensure durability and reliability during long-term use. One end of the connecting rope is fixedly connected to the extension arm 204 or the connecting frame 201, and the specific position is adjusted according to the product design and user habits. This connection method ensures that the lens hood 100 can be hung beside the camera 300 when not in use, facilitating easy access at any time.

[0090] During the shooting process, the user can easily move the lens hood 100 away from the viewfinder through the connecting rope without worrying about dropping or losing it. The connecting rope can also serve as a safety guarantee to prevent the lens hood 100 from being blown off by the wind or falling due to accidental collision when used outdoors.

[0091] The present utility model further provides a photographic device including the camera 300 and the lens hood 100 of the viewfinder in the foregoing embodiment. The specific structure of the lens hood 100 of the viewfinder refers to the above embodiment. Since this photographic device adopts all the technical solutions of all the above embodiments, it at least has all the technical effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. Among them, when the lens hood 100 of the viewfinder is installed on the camera 300, the connecting frame 201 of the lens hood 100 of the viewfinder is directly opposite to the viewfinder opening 304 of the camera 300.

[0092] In this embodiment, the photographic device realizes more efficient light shielding and usage experience by making the lens hood 100 of the viewfinder detachable from the camera 300.

[0093] Specifically, the lens hood 100 is directly opposite to the viewfinder opening 304 of the camera 300 through its connecting frame 201, ensuring that the user obtains a clear and interference-free view during shooting. The installation process of the lens hood 100 is simple. The detachable design enables the user to quickly fix the lens hood 100 on the camera 300 without additional tools. At the same time, the designs of the connecting frame 201, the extension arm 204 and the buckle plate 205 enable the lens hood 100 to closely fit the camera 300, ensuring stability during the shooting process.

[0094] Moreover, by using a lens hood 100 made of flexible materials or silica gel, the photographic device improves the user's comfort and light shielding effect, reducing the interference of ambient light on the viewfinder. And the integrally formed mounting bracket 200 structure improves the durability and stability of the light shielding component, ensuring reliable use in various environments. The design of the connecting rope provides additional safety, preventing the lens hood 100 from accidentally falling off or getting lost during the shooting process.

[0095] The detachable installation of the light-shielding cover 100 of the photographic device of the present utility model on the camera 300 provides good light-shielding performance and convenience in use, enhancing the comfort and flexibility of shooting. The installation of the light-shielding cover 100 no longer depends on the steps or reserved slots of the viewfinder of the camera 300, but is detachably connected to the mounting bracket 200, and then the mounting bracket 200 is detachably connected to the camera 300. Even if there are no steps or slots at the viewfinder opening 304 of the camera 300, the light-shielding cover 100 can still be stably installed.
