Description

Technical Field

[0001] This utility model relates to the field of camera protective case technology, and in particular to a camera protective case with eyepiece reference positioning. Background Technology

[0002] When using a camera, the viewfinder provides a different perspective than the lens captures. This is mainly due to the parallax problem caused by the rangefinder design. The viewfinder and lens are not on the same horizontal line and work independently, causing the subject to shift to one side of the image during shooting, resulting in unusable photos. Utility Model Content

[0003] The purpose of this utility model is to provide a camera protective case with eyepiece reference positioning to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is: A camera protective case with an eyepiece for reference positioning, used in conjunction with a camera, the protective case comprising: The housing has an observation hole at the position corresponding to the camera viewfinder and a lens hole at the position corresponding to the camera lens. An observation lens is installed at the observation hole. The observation lens is made of transparent material and has a viewfinder center located on the side of the observation lens closer to the lens hole. The straight line of light from the center of the viewfinder to the viewfinder center intersects with the straight line of light from the center of the camera lens.

[0005] The technical solution has at least the following beneficial effects: After the protective case is installed on the camera, when using the camera, the user can align the center of the viewfinder with the subject. When the light from the subject passes through the center of the viewfinder and reaches the viewfinder, the light from the subject also passes through the center of the lens, so that the final image of the subject is centered in the photo. By using the center of the viewfinder as a visual reference mark, users no longer need to rely on experience to confirm the center of the image. Simply aligning the subject with the center of the viewfinder on the same straight line of light path will ensure that the subject is ultimately centered in the photo. This allows users to accurately place the subject in the center of the image and quickly center it, improving shooting speed. Furthermore, placing the center of the viewfinder on the protective case simplifies the structure and greatly reduces the cost of redesigning the camera's internal light path.

[0006] As a further improvement to the above technical solution, the center of the viewfinder is located below the observation lens.

[0007] As a further improvement to the above technical solution, the observation lens includes a viewfinder, the projection of the viewfinder in a plane perpendicular to the optical path of the lens is located in the projection of the observation hole in the same plane, a spiral guide line is provided in the viewfinder, and the center of the viewfinder is located at the center of the spiral guide line.

[0008] As a further improvement to the above technical solution, the observation lens is provided with multiple sets of cells arranged at intervals along the vertical direction, and the multiple sets of cells are arranged along the horizontal direction, with the center of the viewfinder located within the cells.

[0009] As a further improvement to the above technical solution, the observation mirror can be detachably installed on the housing.

[0010] As a further improvement to the above technical solution, the housing has a communicating sliding groove on the side wall of the observation hole, and the observation mirror is slidably installed in the sliding groove.

[0011] As a further improvement to the above technical solution, the observation mirror includes a viewfinder and a gripping part connected to each other, the viewfinder being installed inside the housing and the gripping part being located outside the housing.

[0012] As a further improvement to the above technical solution, a limiting part is connected to the viewfinder, the side wall of the sliding groove is connected to the limiting groove, the limiting groove has an opening on the side opposite to the observation hole, and the limiting part passes through the opening and is engaged with the limiting groove.

[0013] As a further improvement to the above technical solution, the side of the grip portion away from the viewfinder portion is arc-shaped.

[0014] As a further improvement to the above technical solution, the housing includes a front housing and a rear housing, which are detachably connected, and the observation mirror is mounted on the front housing. Attached Figure Description

[0022] When using a camera, users typically protect it with a protective case. Furthermore, the camera case, as an external device, can serve as a platform for supporting camera auxiliary equipment. However, existing cameras, such as instant cameras, have the viewfinder located to the side of the lens. In this embodiment, with the lens facing forward, the viewfinder is located on the upper right side of the lens. When using the viewfinder to take a picture and placing the subject in the center of the viewfinder, the subject is positioned on the right side of the actual photo, wasting photographic paper and resulting in an unattractive final image. Therefore, this application provides a camera case with an eyepiece reference positioning feature, which assists the user in placing the subject in the center of the photo during shooting.

[0023] This application provides a camera protective case with an eyepiece for reference positioning, which is used in conjunction with a camera for reference. Figure 1 and Figure 2 The protective case includes a housing 1 and an observation lens 2 mounted on the housing 1. Specifically, the housing 1 has an observation hole 11 at the position corresponding to the camera viewfinder and a lens hole 12 at the position corresponding to the camera lens, that is, the observation hole 11 is located on the upper right side of the lens hole 12. Reference Figure 2 and Figure 3 The observation lens 2 is installed at the observation hole 11. The observation lens 2 is made of transparent material. The observation lens 2 is provided with a viewfinder center part 21. The viewfinder center part 21 is located on the side of the observation lens 2 near the lens hole 12. The straight line of the light path from the viewfinder to the viewfinder center part 21 intersects with the straight line of the light path of the center of the camera lens.

[0024] As can be seen from the above, after the protective case is installed on the camera, when using the camera, the user can align the center viewfinder 21 with the subject. When the light from the subject passes through the center viewfinder 21 and reaches the viewfinder, the light from the subject simultaneously enters the lens along the light path at the center of the lens. After pressing the shutter, the final image of the subject is positioned in the center of the photo.

[0025] By using the viewfinder center 21 as a visual reference mark, users do not need to rely on experience to confirm the center of the lens image. They only need to align the subject with the viewfinder center 21 on the same straight line of the light path to ensure that the subject is ultimately located in the center of the image. This allows users to accurately place the subject in the center of the image and quickly center the subject, thus improving shooting speed. At the same time, placing the viewfinder center on the protective shell simplifies the structure and greatly reduces the cost of redesigning the internal light path of the camera.

[0026] In this application, the viewfinder center 21 is a polygon or circle drawn on the surface of the observation lens 2 with paint. In this embodiment, the viewfinder center 21 is circular. When taking a picture, the user can place the field of view of the subject within the viewfinder center 21, thereby placing the entire subject within the camera's field of view.

[0027] Specifically, the viewfinder center 21 is located on the surface of the viewfinder 22, so that the viewfinder center 21 can be directly engraved on the surface of the viewfinder, which is convenient for the manufacturer to process.

[0028] Furthermore, since the viewfinder of an instant camera is located above the lens, the final image of the subject will be positioned at the top of the picture when shooting. Therefore, the center of view 21 is set below the viewing lens 2. When shooting, the subject is moved upwards relative to the viewfinder 2 to be aligned with the center of the viewing lens 2, so that the subject is positioned below the viewfinder and aligned with the center of the lens, thus making the subject centrally located in the vertical direction.

[0029] Reference Figure 3 In some embodiments, the viewing lens 2 includes a viewfinder 22. The projection of the viewfinder 22 onto a plane perpendicular to the lens optical path is located within the projection of the viewing aperture 11 onto the same plane. A spiral guide line 23 is provided inside the viewfinder 22, and the center viewfinder 21 is located at the center of the spiral guide line 23. When the user locks onto the subject through the center viewfinder 21, the horizontal lines, perspective lines, or secondary objects in the surrounding background can be actively aligned or paralleled by the user with specific sections of the spiral curve. Without relying on electronic assistance or post-processing, the precise positioning of the photographic subject and the geometric optimization of the overall structure of the image are completed simultaneously at the moment of shooting, thereby systematically improving the compositional standardization, visual balance, and professionalism of the final image.

[0030] Specifically, the center of the spiral guide line 23 is located on the side of the observation mirror 2 closer to the lens. The spiral guide line 23 can better help the user to frame the shot and position the subject of the photograph, thus improving the practicality of the observation mirror 2.

[0031] In other embodiments, reference is made to Figure 4The observation lens 2 has multiple sets of cells 24 arranged at intervals along the vertical direction and horizontally. The center of view 21 is located within each cell 24. This design achieves the following technical effects: This gridded structure divides the field of view into a high-precision two-dimensional coordinate reference system, with each cell 24 directly corresponding to the coordinates of a specific area in the final image. When the user aligns the center of view 21 with a photographic subject, they can accurately and intuitively predict and control the subject's specific position in the final photo based on the relative position of the cell 24 within the grid. This design allows users to quickly and repeatedly compose the subject in any preset position within the frame, greatly enhancing compatibility with various composition rules and operational efficiency, and significantly improving the practicality and positioning accuracy of the observation lens 2 in complex composition scenarios.

[0032] In some embodiments, refer to Figure 2 and Figure 5 The observation lens 2 can be detachably installed on the housing 1. In this way, when the surface of the observation lens 2 is worn after long-term use, causing the center of the viewfinder 21 to become blurry, a new observation lens 2 can be replaced to regain a clear view of the center of the viewfinder 21.

[0033] Specifically, the housing 1 has a connecting sliding groove 13 on the side wall of the observation hole 11. The observation lens 2 is slidably installed in the sliding groove 13. The cross-sectional area and shape of the sliding groove 13 are adapted to the area and shape of the viewing part 22 of the observation lens 2 on the same cross section, so that the observation lens 2 can be smoothly slid into the housing 1.

[0034] In some embodiments, the viewing mirror 2 further includes a gripping part 25 connected to the viewfinder 22. The viewfinder 22 is installed inside the housing 1, and the gripping part 25 is located outside the housing 1. When it is necessary to pull out the viewing mirror 2, the user can directly grasp the gripping part 25 and pull out the entire viewing mirror 2.

[0035] In some embodiments, a limiting part 26 is connected to the viewfinder 22, and the side wall of the sliding groove 13 is connected to a limiting groove 14. The limiting groove 14 has an opening on the side away from the observation hole 11. The limiting part 26 passes through the opening and engages with the limiting groove 14. When the limiting part 26 abuts against the bottom of the limiting groove 14, the projection of the observation hole 11 on the plane perpendicular to the straight line of the lens optical path is located in the projection of the viewfinder 22 on the same plane. After the viewfinder 22 of the observation lens 2 is installed into the housing 1, the limiting part 26 abuts against the limiting groove 14, so that the viewfinder 22 can completely cover the observation hole 11 in the housing 1 without colliding with the housing 1, reducing the possibility of damage to the observation lens 2.

[0036] Specifically, the side of the grip 25 away from the viewfinder 22 is curved. The curved design reduces the sharp edges on the grip 25, thereby reducing the risk of the grip 25 scratching the user.

[0037] To facilitate the installation of housing 1, in this embodiment, refer to... Figure 1 The housing 1 includes a front housing 3 and a rear housing 4, which are detachably connected. The observation lens 2 is installed on the front housing 3 and located in front of the viewfinder. With this design, the housing 1 is divided into two parts, and the front housing 3 and the rear housing 4 can be directly covered on the camera during use.

[0038] Specifically, the front shell 3 and the rear shell 4 are connected by a hinge. Both the side of the front shell 3 away from the hinge and the side of the rear shell 4 away from the hinge are provided with a buckle. The two buckles are connected to lock the front shell 3 and the rear shell 4 to form the shell 1.

[0039] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
