Description

Technical Field

[0001] This utility model belongs to the field of underwater photography, and in particular relates to a shutter mechanism and a waterproof housing for a camera. Background Technology

[0002] In the field of underwater photography, the waterproof housing for cameras is a core component ensuring the safe and stable operation of cameras underwater. As underwater photography becomes increasingly popular, the demand for functional expansion continues to grow. To meet users' pursuit of diverse shooting effects, brackets are often added to the camera's waterproof housing to mount auxiliary equipment such as fill lights and wide-angle lenses. The addition of such equipment effectively improves underwater lighting conditions, broadens the field of view, and significantly enhances the flexibility and functionality of underwater photography.

[0003] However, the addition of the bracket inevitably alters the original structure and spatial layout of the waterproof housing, directly resulting in reduced operating space for the shutter mechanism. This spatial limitation makes it difficult for users to operate the shutter normally, or causes significant inconvenience during operation, thus affecting the shooting experience and efficiency. To solve this problem, existing technologies typically require replacing the shutter mechanism with a compatible one. Furthermore, when replacing the shutter mechanism, the original shutter mechanism must be disassembled, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a shutter mechanism that solves the problem of limited shutter operation space and the need to replace the shutter mechanism due to the addition of a bracket to the waterproof housing of the camera.

[0005] This utility model provides a shutter mechanism, assembled in a waterproof housing for a camera, wherein the waterproof housing is provided with a shutter transmission structure corresponding to the camera's shutter, and the shutter mechanism includes:

[0006] A shutter drive unit has one end rotatably connected to the waterproof housing and the other end having a first operating end. The shutter drive unit has a shutter abutment portion corresponding to the shutter transmission structure. When the first operating end is subjected to a pressing force along the pressing direction, the shutter drive unit rotates around the waterproof housing and drives the shutter abutment portion to press the shutter transmission structure.

[0007] An operating extension member has one end rotatably connected to the shutter drive member and the other end having a second operating end. The operating extension member can rotate relative to the shutter drive member and switch between an avoidance state and an extended state. In the avoidance state, the operating extension member avoids the first operating end in the pressing direction. In the extended state, the second operating end is offset from the first operating end in the pressing direction and is in a preset operating position. When the second operating end is subjected to a pressing force along the pressing direction, the operating extension member drives the shutter drive member to rotate and causes the shutter abutment part to press the shutter transmission structure.

[0008] Optionally, one end of the operating extension is rotatably connected to the side of the shutter drive member facing away from the shutter transmission structure.

[0009] Optionally, the shutter drive component has two spaced transition strips formed on the side facing away from the shutter drive structure;

[0010] One end of the operating extension is located between the two adapter strips and is connected and engaged with the two adapter strips.

[0011] Optionally, the operating extension member, in the avoidance state and / or the extended state, can engage and position with the adapter strip to restrict the rotation of the operating extension member relative to the shutter drive member.

[0012] Optionally, at least one of the operating extension members has a first engaging structure facing the side of the adapter strip;

[0013] At least one of the adapter strips has a second engaging structure facing the operating extension;

[0014] At least one of the adapter strips has a third engaging structure facing the operating extension;

[0015] In the avoidance state, the first engaging structure engages and is positioned with the second engaging structure, while in the extended state, the first engaging structure engages and is positioned with the third engaging structure.

[0016] Optionally, the first engaging structure is either a concave structure or a convex spherical structure;

[0017] The second and third engaging structures are either concave structures or convex spherical structures.

[0018] Optionally, a connecting shaft is provided between the two connecting strips, and the two ends of the connecting shaft are respectively connected to the two connecting strips;

[0019] The operating extension is connected to the adapter shaft, and the adapter shaft enables it to be connected and engaged with the two adapter strips.

[0020] Optionally, the shutter drive and the operation extension are in the form of a sheet;

[0021] In the avoidance state or the extension state, the operating extension member and the shutter drive member are stacked on top of each other.

[0022] Optionally, the operating surfaces of the first operating end and / or the second operating end have tactile protrusions.

[0023] This utility model also provides a waterproof housing for a camera, including the shutter mechanism as described above.

[0024] Based on the structural design of this utility model, by switching the state of the operating extension component, the operating end can be extended to a preset operating position, i.e., a suitable position, when space is limited. This makes operation convenient and eliminates the need to disassemble or replace the original shutter mechanism, saving time and effort. Simultaneously, the coexistence of two operating modes enhances the adaptability of the shutter mechanism, meeting user needs regardless of whether additional equipment is installed, optimizing the shooting experience, improving shooting efficiency, and avoiding inconvenience caused by limited operating space.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0042] This utility model embodiment provides a shutter mechanism, which is assembled in a waterproof housing for a camera. The waterproof housing is provided with a shutter transmission structure corresponding to the camera's shutter. It should be noted that the shutter transmission structure will be displaced relative to the waterproof housing when it is subjected to pressing pressure, so as to transmit the pressing pressure to the camera's shutter and realize the pressing of the shutter.

[0043] Please see Figures 1 to 7 The shutter mechanism includes a shutter drive 100 and an operating extension 200.

[0044] Specifically, one end of the shutter drive 100 is rotatably connected to the waterproof housing (not shown in the figure), and the other end has a first operating end 110. The shutter drive 100 has a shutter abutment portion 120 corresponding to the shutter transmission structure 300. When the first operating end 110 is subjected to a pressing force in the pressing direction, the shutter drive 100 rotates around the waterproof housing and drives the shutter abutment portion 120 to press the shutter transmission structure 300. It should be noted that the shutter abutment portion 120 is preferably a protrusion on the shutter drive 100 facing the shutter transmission structure 300. In this way, the protrusion direction points to the trigger center of the shutter transmission structure 300, ensuring the accuracy of triggering.

[0045] One end of the operating extension member 200 is rotatably connected to the shutter drive member 100, and the other end has a second operating end 210. The operating extension member 200 can rotate relative to the shutter drive member 100 and switch between a avoidance state and an extended state. In the avoidance state, see... Figure 1 The operating extension member 200 avoids the first operating end 110 in the pressing direction, that is, the projection of the operating extension member 200 in the pressing direction does not cover the first operating end 110, so as to avoid affecting the user's pressing of the first operating end 110. In the extended state, see Figure 6 and Figure 7 The second operating end 210 is offset from the first operating end 110 in the pressing direction and is in a preset operating position. When the second operating end 210 is subjected to a pressing force in the pressing direction, the operating extension 200 drives the shutter drive 100 to rotate and drives the shutter abutment 120 to press the shutter transmission structure 300. The preset operating position can be adapted to the actual structure of the waterproof housing and the bracket so that the user can press the second operating end 210 when the bracket is set.

[0046] The usage process of this utility model is as follows:

[0047] Direct operation in a avoidance situation, i.e., a standard scenario: when the waterproof housing is not equipped with auxiliary equipment (such as a supplementary lighting bracket) or there is sufficient operating space, see [reference]. Figure 1 and Figure 2The operating extension 200 is in a avoidance state, and its projection in the pressing direction (usually an axial direction perpendicular to the housing surface) completely avoids the first operating end 110. The user directly presses the first operating end 110, and the pressing force is transmitted to the shutter drive 100 through the first operating end 110. Since one end of the shutter drive 100 is rotatably connected to the waterproof housing (forming a fixed fulcrum), the pressing force causes the drive to rotate around the fulcrum, driving the shutter abutment 120 at the other end to move towards the shutter transmission structure 300. The shutter abutment 120 presses against the shutter transmission structure 300 inside the housing, triggering the camera shutter to complete the shooting. After the operation is completed, the pressing force is released, and during this process, the operating extension 200 remains in the avoidance state.

[0048] Indirect operation in the extended state, i.e., scenarios where space is limited due to the installation of a bracket: When the waterproof housing is fitted with auxiliary equipment, causing the first operating end 110 to be obstructed or operation to be inconvenient, the user can move the operating extension member 200 to rotate it around the rotational connection point with the shutter drive member 100, switching from the avoidance state to the extended state. See [link to relevant documentation]. Figure 6 and Figure 7 At this time, the second operating end 210 is misaligned with the first operating end 110 in the pressing direction (e.g., offset to the side, above, or below the waterproof housing) and reaches the preset operating position (avoiding obstacles such as brackets). When the user presses the second operating end 210, the pressing force is transmitted to the shutter drive 100 through the operating extension 200, causing the shutter drive 100 to rotate around the fulcrum of the housing, which in turn causes the shutter abutment 120 to press the transmission structure and trigger the camera's shutter.

[0049] Based on the structural design of this utility model, by switching the state of the operating extension member 200, the operating end can be extended to a preset operating position, i.e., a suitable position, when space is limited. This makes operation convenient and eliminates the need to disassemble or replace the original shutter mechanism, saving time and effort. Simultaneously, the coexistence of two operating modes enhances the adaptability of the shutter mechanism, meeting user needs regardless of whether additional equipment is installed, optimizing the shooting experience, improving shooting efficiency, and avoiding inconvenience caused by limited operating space.

[0050] Please see Figure 1 and Figure 2 In this embodiment of the invention, one end of the operating extension member 200 is rotatably connected to the side of the shutter drive member 100 facing away from the shutter transmission structure 300. Based on this, the connection point is located on the back of the shutter drive member 100, decoupling the rotational movement of the operating extension member 200 from the pressing movement of the shutter abutment part 120, thus avoiding interference between the two in three-dimensional space. Specifically, in use, the shutter abutment part 120 presses the shutter transmission structure 300 downwards along the axial direction, causing the shutter transmission structure 300 to move below the shutter drive member 100, while the operating extension member 200 rotates in the transverse plane above the shutter drive member 100; the two movements do not interfere with each other.

[0051] Please see Figures 1 to 7 In this embodiment of the invention, the shutter drive member 100 has two spaced-apart transition strips 130 on its side facing away from the shutter transmission structure 300; one end of the operating extension member 200 is located between the two transition strips 130 and is connected to them. The two transition strips 130 constitute the physical carrier of the rotation fulcrum, and their spaced arrangement forms a stable support base, improving the rotational accuracy of the operating extension member 200.

[0052] Please see Figures 1 to 7 In this embodiment of the invention, the operating extension member 200, in both the avoidance and extended states, can engage with the adapter strip 130 for positioning, thereby restricting the rotation of the operating extension member 200 relative to the shutter drive member 100. This engaging and positioning structure creates a locking mechanism between the operating extension member 200 and the adapter strip 130, enhancing their mutual constraint and effectively limiting their free rotation in the non-operating state, thus ensuring the stability of the shutter mechanism in both the avoidance and extended states.

[0053] In other embodiments, the operating extension member 200 may engage and position only in one of the avoidance state and the extended state, or it may engage and position only with one of the two transition strips 130, whichever is required.

[0054] Furthermore, in this embodiment of the present invention, at least one of the operating extension members 200 faces the first engaging structure 220 on the side of the adapter strip 130;

[0055] At least one of the adapter strips 130 has a second engaging structure 131 facing the operating extension 200;

[0056] At least one of the adapter strips 130 has a third engaging structure 132 facing the operating extension 200;

[0057] In the avoidance state, the first engaging structure 220 and the second engaging structure 131 engage and position each other, while in the extended state, the first engaging structure 220 and the third engaging structure 132 engage and position each other.

[0058] Thus, the first engaging structure 220 can engage and position with both the second engaging structure 131 and the third engaging structure 132, eliminating the need for two engaging structures in the operating extension 200 and simplifying its structure.

[0059] In this embodiment, both adapter strips 130 are provided with a second engaging structure 131 and a third engaging structure 132.

[0060] Specifically, in this embodiment of the present invention, the first engaging structure 220 is one of a concave structure and a convex spherical structure;

[0061] The second engaging structure 131 and the third engaging structure 132 are the other of the concave structure and the convex spherical structure.

[0062] Among these features, spherical contact makes the state switching process smoother.

[0063] Specifically, in this embodiment, the first engaging structure 220 is a convex spherical structure, while the second engaging structure 131 and the third engaging structure 132 are concave structures.

[0064] Please see Figures 1 to 7 In this embodiment of the invention, a connecting shaft is provided between the two connecting strips 130, with both ends of the connecting shaft connected to the two connecting strips 130 respectively; the operating extension member 200 is connected to the connecting shaft and achieves a connecting fit with the two connecting strips 130 through the connecting shaft. Achieving a connecting fit through the connecting shaft helps to simplify the structure and reduce manufacturing costs.

[0065] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 In this embodiment of the invention, the shutter drive 100 and the operating extension 200 are sheet-like structures. In the avoidance or extended state, the operating extension 200 and the shutter drive 100 are stacked on top of each other. When folded, the operating extension 200 is stacked on the back of the shutter drive 100, occupying little space. When extended, the operating extension 200 rotates outward, forming a certain angle with the shutter drive 100, with the second operating end 210 in a preset position. At this time, the two may still partially overlap, maintaining a compact structure. This sheet-like structure and stacked arrangement greatly improves the space utilization of the shutter mechanism. In situations where the waterproof housing space is limited, this structure allows the operating extension 200 to fit tightly against the shutter drive 100 when not in use, without occupying additional space and avoiding spatial conflicts with other components such as auxiliary equipment brackets. When the extended state is needed, the extended part is rotated out by 200. Because it is a sheet structure, it is thin and will not take up too much space even when it is in the extended state, making it suitable for the complex space environment after the equipment is installed.

[0066] Please see Figures 1 to 7 In this embodiment of the invention, the operating surfaces of the first operating end 110 and the second operating end 210 have tactile protrusions. These tactile protrusions allow users to quickly locate the operating position using their fingertips, avoiding accidental touches during blind operation.

[0067] In other embodiments, the first operating terminal 110 and the second operating terminal 210 may be provided with tactile protrusions according to usage requirements.

[0068] This utility model also proposes a waterproof housing for a camera, which includes a shutter mechanism. The specific structure of the shutter mechanism is as described in the above embodiments. Since this waterproof housing for a camera adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0069] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
