Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to an extended protective shell and a photographic system. Background Technology

[0002] Action cameras are popular for their ability to capture high-quality video and images in various environments. These cameras typically require mounting on other photographic equipment, such as tripods, helmets, or handheld stabilizers, to meet different shooting needs. To achieve this, action cameras are usually equipped with mounting interfaces, such as hot shoe mounts, for quick connection to compatible accessories. Protective cases, as a common accessory, not only protect the camera from environmental damage but also provide additional mounting options, enhancing its flexibility of use.

[0003] Currently, action camera extension cases typically come in two sizes: one designed for landscape shooting and the other for portrait shooting. These cases achieve quick installation by using specific structures and mounting methods, such as an integrated cold shoe mount, to match the camera's top hot shoe interface.

[0004] However, the limitation of existing protective cases is that their design is geared towards a single shooting direction. Users can only choose between horizontal or vertical extended protective cases according to their shooting needs, and cannot quickly switch between the two modes, which limits the applicability of protective cases in various shooting scenarios. Utility Model Content

[0005] The main purpose of this invention is to propose an extended protective shell that solves the problem that extended protective shells in related technologies cannot quickly switch between two modes.

[0006] To achieve the above objectives, this utility model proposes an extended protective shell for use in photographic equipment. The extended protective shell includes a housing with a mounting cavity for mounting a sports camera. The housing has a first cold shoe mount and a second cold shoe mount respectively provided on its two adjacent sides.

[0007] In some embodiments, the housing is elongated, with a first cold shoe mount at one end of the housing in the length direction and a second cold shoe mount at one side of the housing in the width direction.

One end of the housing is provided with a first protrusion, and one end of the first threaded post is provided with a first groove adapted to the first protrusion. A first screw through hole is formed in the first threaded post, penetrating the bottom wall of the first groove.

[0012] In some embodiments, the second cold shoe includes a second locking knob, a second threaded post, and a second cold shoe plate. The second locking knob is sleeved with the second threaded post. One end of the second threaded post is connected to one side of the housing, and the second cold shoe plate is connected to the other end of the second threaded post. A second protrusion is formed on one side of the housing, and a second groove adapted to the second protrusion is formed at one end of the second threaded post. A second screw through hole is formed in the second threaded post, penetrating the bottom wall of the second groove.

[0013] In some embodiments, the first cold shoe mount includes a first locking knob, a first threaded post, and a first cold shoe plate. The first locking knob is sleeved on the first threaded post. One end of the first threaded post is provided with a first retaining plate, and the other end of the first threaded post is connected to the first cold shoe plate. The first retaining plate is provided with a first retaining protrusion on at least one side in its width direction.

[0014] One end of the housing is provided with a first bayonet opening, and the first bayonet opening is provided with a first slot that is adapted to the first holding protrusion; the first card plate is provided with a first strip opening, and extends along the side of the first card plate where the first holding protrusion is provided.

[0015] In some embodiments, the second cold shoe seat includes a second locking knob, a second threaded post, and a second cold shoe plate. The second locking knob is sleeved with the second threaded post. One end of the second threaded post is provided with a first retaining plate, and the other end of the second threaded post is connected to the second cold shoe plate. The second retaining plate is provided with a second retaining protrusion on at least one side in its width direction.

[0016] A second latch is formed on one side of the housing, and a second slot is formed inside the second latch to match the second holding protrusion; a second strip opening is formed on the second plate, and the second strip opening extends along the side of the second plate where the second holding protrusion is provided.

[0017] The present invention further proposes a photography system, including a photography device, an action camera, and an extended protective shell as described in the foregoing embodiments. The top of the photography device is configured with a cold shoe groove adapted to the first cold shoe mount and the second cold shoe mount, and the action camera is mounted inside the extended protective shell.

[0018] The beneficial effects of this utility model are as follows: by setting a first cold shoe and a second cold shoe on the adjacent two sides of the extended protective shell, a single extended protective shell can flexibly switch between horizontal and vertical shooting modes, solving the limitation of existing protective shell designs for a single shooting direction. This allows users to quickly adjust the shooting direction according to the shooting scene without replacing extended protective shells of different specifications, improving the applicability and ease of use of the extended protective shell in multi-scene shooting, and avoiding the equipment replacement costs and time losses caused by users switching shooting directions.

[0038] Reference Figure 1 This utility model proposes an extended protective shell 10 for use in photographic equipment. The extended protective shell 10 includes a shell 100, which has a mounting cavity 101 for mounting an action camera. The shell 100 has a first cold shoe mount 200 and a second cold shoe mount 300 respectively on its two adjacent sides.

[0039] In this embodiment, the housing 100 of the extended protective shell 10 adopts a semi-enclosed design, with an open surface that communicates with the mounting cavity 101. An action camera can enter the mounting cavity 101 through the open surface to mount the entire extended protective shell 10 onto other photographic equipment, such as tripods, helmets, or handheld stabilizers, to meet different shooting needs. The shape of the housing 100 can be a regular geometric shape such as a cuboid, cube, or cylinder, or it can be customized according to the specific outline of the action camera. In this embodiment, the housing 100 can adopt a cuboid structure, with a first cold shoe mount 200 and a second cold shoe mount 300 respectively provided on its two adjacent sides.

[0040] Specifically, the first cold shoe mount 200 is disposed on the first side of the housing 100, and the second cold shoe mount 300 is disposed on the second side of the housing 100. The first side and the second side can be perpendicular to each other. Both the first cold shoe mount 200 and the second cold shoe mount 300 adopt the standard cold shoe interface specification, enabling compatible connection with the cold shoe slots of commonly available photographic equipment. For example, during use, when the first cold shoe mount 200 is connected to the cold shoe slot of the photographic equipment, the action camera is in a vertical shooting state; when the second cold shoe mount 300 is connected to the cold shoe slot of the photographic equipment, the action camera is in a horizontal shooting state. Users can flexibly choose to use either the first cold shoe mount 200 or the second cold shoe mount 300 according to actual shooting needs, achieving quick switching between horizontal and vertical shooting modes without disassembling the action camera or replacing other accessories.

[0041] The beneficial effects of this utility model are as follows: by setting a first cold shoe mount 200 and a second cold shoe mount 300 on the adjacent two sides of the housing 100 of the extended protective shell 10, the single extended protective shell 10 can flexibly switch between horizontal and vertical shooting modes, which solves the limitation of existing protective shell designs for a single shooting direction. This allows users to quickly adjust the shooting direction according to the shooting scene without replacing the extended protective shell 10 with different specifications, improving the applicability and ease of use of the extended protective shell 10 in multi-scene shooting. It avoids the equipment replacement costs and time losses caused by users switching shooting directions. At the same time, the structural design is simple and reliable, the manufacturing cost is low, it is easy to mass-produce, and it has good market promotion value.

[0042] Continue reading Figure 1 In this embodiment, the housing 100 is elongated, with a first cold shoe seat 200 at one end of its length direction and a second cold shoe seat 300 at one side of its width direction.

[0043] In this embodiment, taking the shell 100 as an example, the length direction of the shell 100 is perpendicular to the width direction, forming a regular rectangular cross-sectional structure.

[0044] Specifically, the first cold shoe mount 200 is located at the end of the housing 100 along its length, with the opening of its cold shoe groove parallel to the length of the housing 100. When the first cold shoe mount 200 is connected to photographic equipment, the main shooting direction of the action camera extends along the length of the housing 100, achieving a horizontal shooting mode. The second cold shoe mount 300 is located on the side of the housing 100 along its width, with the opening of its cold shoe groove parallel to the width of the housing 100. When the second cold shoe mount 300 is connected to photographic equipment, the main shooting direction of the action camera extends along the width of the housing 100, achieving a vertical shooting mode.

[0045] During use, users can selectively connect either the first cold shoe mount 200 or the second cold shoe mount 300, depending on the specific needs of the shooting scenario. For scenes requiring a wide field of view, such as landscape photography or group photos, the first cold shoe mount 200 can be selected for horizontal shooting; for scenes requiring a high field of view, such as portrait photography or panoramic building shots, the second cold shoe mount 300 can be selected for vertical shooting. The entire switching process does not require disassembling or reinstalling the action camera; simply changing the connection method of the cold shoe mount is sufficient to adjust the shooting direction.

[0046] By setting a first cold shoe mount 200 at one end of the length direction and a second cold shoe mount 300 at one side of the width direction of the extended protective case 10, the single extended protective case 10 can flexibly switch between horizontal and vertical shooting modes. This solves the limitation of existing protective case designs that are only designed for a single shooting direction. Users can quickly adjust the shooting direction according to the shooting scene without having to replace the extended protective case 10 with different specifications. This improves the applicability and ease of use of the extended protective case 10 in multiple shooting scenarios and avoids the equipment replacement costs and time losses caused by users switching shooting directions.

[0047] Continue reading Figure 1 In this embodiment, a notch 102 for operating the action camera buttons is provided on one side of the housing 100. The position of the notch 102 corresponds to the position of the main operation buttons of the action camera, including key function buttons such as the power button, record button, and mode switch button. The shape and size of the notch 102 are specially designed according to the button layout of different models of action cameras to ensure that after the action camera is installed in the mounting cavity 101, the user can still directly access and operate the various function buttons of the camera through the notch 102.

[0048] By providing an operation notch 102 on the side of the housing 100, users can perform common operations such as powering on / off, starting recording, stopping recording, and switching shooting modes without removing the action camera from the extended protective case 10, greatly improving ease of use and operational efficiency. At the same time, the edges of the notch 102 are rounded to prevent scratches to fingers during operation, thus improving safety.

[0049] See Figure 2 In this embodiment, a magnetic attachment 103 for attaching an action camera is provided on the side wall of the housing 100. The magnetic attachment 103 is made of permanent magnet material and has moderate magnetic strength, which allows it to firmly attach the action camera while also making it easy for the user to remove the camera when needed. The magnetic attachment 103 can be a single magnet or a combination of multiple magnets, configured appropriately according to the weight and size of the action camera.

[0050] It should be noted that the installation position of the magnetic suction member 103 in this embodiment can be installed on the side of the housing 100 located in the mounting cavity 101, or it can be installed on the side of the housing 100 facing away from the mounting cavity 101.

[0051] The magnetic attachment 103 is positioned to correspond to the metal casing or magnetic interface of the action camera. When the action camera enters the mounting cavity 101 through the open surface, the magnetic attachment 103 automatically attracts the action camera, achieving quick positioning and fixation. This magnetic fixation method eliminates the need for additional mechanical locking devices, simplifying the installation and disassembly process. Users simply need to gently place the action camera into the mounting cavity 101 to complete the installation, and only need to apply appropriate pulling force to separate it.

[0052] The magnetic attachment 103 not only improves the installation stability of the action camera within the housing 100, preventing it from loosening or falling off during action shooting, but also greatly simplifies the user's operation process, enhancing the user experience and ease of use.

[0053] See Figure 1 In this embodiment, the first cold shoe holder 200 and the second cold shoe holder 300 are integrally formed with the housing 100.

[0054] In this embodiment, the first cold shoe holder 200 and the second cold shoe holder 300 are integrally formed with the housing 100, which can be achieved by injection molding, die casting or 3D printing.

[0055] Specifically, when using injection molding, the housing 100 and the cold shoe mount use the same engineering plastic material, such as ABS, PC, or nylon, and are formed in one piece in the injection mold to ensure a tight fit between the components. When using die casting, aluminum alloy or zinc alloy materials can be selected, and the housing 100 and the cold shoe mount are integrally formed through high-pressure die casting. When using 3D printing, 3D printing materials such as PLA, ABS, or nylon can be selected, and the complete extended protective shell 10 can be directly printed through digital modeling.

[0056] The unibody design eliminates seams and weak points that can exist in traditional assembly methods, significantly improving the overall structural strength and stability. Simultaneously, unibody molding avoids the assembly process between multiple parts, reducing production costs and manufacturing complexity, and increasing production efficiency. Furthermore, the unibody surface is smoother and has a better appearance, while reducing dust and dirt accumulation, facilitating daily cleaning and maintenance.

[0057] See Figure 2 , Figure 3 , Figure 4 and Figure 5In this embodiment, the first cold shoe holder 200 includes a first locking knob 201, a first threaded post 202, and a first cold shoe plate 204. The first locking knob 201 is sleeved on the first threaded post 202. One end of the first threaded post 202 is connected to one end of the housing 100, and the first cold shoe plate 204 is connected to the other end of the first threaded post 202. One end of the housing 100 is provided with a first protrusion 104, and one end of the first threaded post 202 is provided with a first groove 203 that is adapted to the first protrusion 104. A first screw through hole 202a is formed in the first threaded post 202 that penetrates the bottom wall of the first groove 203.

[0058] In this embodiment, the first cold shoe base 200 can be detachably connected to the second cold shoe base 300, which is integrally formed with the housing 100 on one side. Specifically, the other end of the first threaded post 202 is fixedly connected to the first cold shoe plate 204 by means of threaded connection, adhesive bonding, or welding, forming an integral connection assembly. The first cold shoe plate 204 adopts a standard cold shoe interface specification and can be inserted into the cold shoe groove of the photographic device. The first locking knob 201 is sleeved on the first threaded post 202. After the first cold shoe plate 204 is connected to the cold shoe groove of the photographic device, the connection is locked and fixed by rotating the first locking knob 201 to prevent the first cold shoe plate 204 from loosening or falling off in the cold shoe groove.

[0059] One end of the housing 100 is provided with a first protrusion 104, which protrudes outward from the surface of the housing 100 and has a specific shape and size. The first threaded post 202 and the first protrusion 104 can be fixed by means of screw connection, snap-fit ​​connection, or plug-in connection. In the screw connection method, the screw passes through the first screw through hole 202a in the first threaded post 202 and is directly screwed into the threaded hole in the first protrusion 104 to achieve a reliable mechanical connection.

[0060] The first groove 203 at one end of the first threaded post 202 is directional; that is, the shape of the first groove 203 is designed as a non-circular cross-section, such as square, rectangular, elliptical, or irregular groove, which perfectly matches the outer contour of the first protrusion 104. This asymmetrical fit ensures that the first protrusion 104 can only be inserted into the first groove 203 in a specific direction, playing a role in precise positioning and preventing the first protrusion 104 from rotating within the first groove 203 after connection, thus ensuring the directional accuracy and connection stability of the first cold shoe seat 200 after installation.

[0061] With this structural design, the first locking knob 201 is specifically used to lock the connection between the first cold shoe plate 204 and the cold shoe groove of the camera device, ensuring a firm connection between the camera device and the extended protective shell 10. At the same time, the matching design of the first protrusion 104 and the first groove 203 ensures accurate positioning of the connection, improving the stability and reliability of the entire system.

[0062] Continue reading Figure 2 , Figure 3 , Figure 4 and Figure 5 The second cold shoe holder 300 includes a second locking knob 301, a second threaded post 302, and a second cold shoe plate 304. The second locking knob 301 is sleeved with the second threaded post 302. One end of the second threaded post 302 is connected to one side of the housing 100, and the second cold shoe plate 304 is connected to the other end of the second threaded post 302. A second protrusion 105 is formed on one side of the housing 100. A second groove 303 adapted to the second protrusion 105 is formed at one end of the second threaded post 302. A second screw through hole 302a is formed in the second threaded post 302, penetrating the bottom wall of the second groove 303.

[0063] In this embodiment, the second cold shoe holder 300 can also be configured with a detachable connection method, based on the screw connection between the first cold shoe holder 200 and the housing 100. Specifically, the other end of the second threaded post 302 is firmly connected to the second cold shoe plate 304 by means of threaded connection, adhesive bonding, or welding, forming a complete connection assembly. The second cold shoe plate 304 also adopts the standard cold shoe interface specification to ensure compatibility with the cold shoe slots of various photographic devices. The second locking knob 301 is sleeved on the second threaded post 302. When the second cold shoe plate 304 is inserted into the cold shoe slot of the photographic device, the connection can be effectively locked by rotating the second locking knob 301, ensuring the stable fixation of the second cold shoe plate 304 in the cold shoe slot.

[0064] A second protrusion 105 is provided on one side of the housing 100. This second protrusion 105 has a similar structure to the first protrusion 104, protruding outward from the side of the housing 100. The second threaded post 302 is connected to the housing 100 by a screw. The screw passes through the second screw through-hole 302a in the second threaded post 302 and is screwed into the pre-set threaded hole in the second protrusion 105, forming a reliable mechanical connection. This connection method facilitates the installation, disassembly, and maintenance of the second cold shoe mount 300.

[0065] The second groove 303 at one end of the second threaded post 302 has a non-circular cross-section, such as a square, rectangular, or other irregularly shaped groove structure, that perfectly matches the second protrusion 105, precisely fitting the outer contour of the second protrusion 105. This directional fit design ensures that the second protrusion 105 can only be inserted into the second groove 303 in the correct direction, effectively preventing accidental rotation of the second protrusion 105 within the second groove 303 after connection, thus guaranteeing the accuracy of the installation direction of the second cold shoe seat 300 and the stability of the overall connection.

[0066] By adopting the same connection structure and locking method as the first cold shoe mount 200, the second cold shoe mount 300 provides a reliable connection while also ensuring the uniformity of the entire extended protective shell 10 design and the standardization of the manufacturing process, reducing production costs and improving the overall quality of the product.

[0067] See Figure 6 , Figure 7 , Figure 8 and Figure 9 In this embodiment, the first cold shoe holder 200 includes a first locking knob 201, a first threaded post 202, and a first cold shoe plate 204. The first locking knob 201 is sleeved on the first threaded post 202. One end of the first threaded post 202 is provided with a first retaining plate 205, and the other end of the first threaded post 202 is connected to the first cold shoe plate 204. The first retaining plate 205 is provided with a first retaining protrusion 207 on at least one side in its width direction.

[0068] One end of the housing 100 is provided with a first bayonet 106, and the first bayonet 106 is provided with a first slot 107 that is adapted to the first holding protrusion 207; a first strip opening 208 is provided on the first card plate 205, and the first holding protrusion 207 extends along the side of the first card plate 205.

[0069] In this embodiment, the second cold shoe holder 300 can be integrally formed with one side of the housing 100. The first cold shoe holder 200 adopts a quick-release connection with the housing 100. Specifically, the first locking plate 205, as the core component of the quick-release mechanism, has a shape and size that precisely matches the first latch 106 at the end of the housing 100. During installation, the first locking plate 205 is inserted along the guide surface of the first latch 106. The first holding protrusion 207 will be subjected to a certain amount of compression deformation during the insertion process. When the first locking plate 205 is fully inserted, the first holding protrusion 207 will automatically spring into the first latch 107 under the elastic recovery action, forming a reliable latching connection.

[0070] The first strip opening 208 provides the first clamping plate 205 with a certain degree of elastic deformation capability, facilitating the deformation of the first clamping protrusion 207 during insertion and removal. Simultaneously, the first strip opening 208 extends along the side of the first clamping protrusion 207, ensuring a reasonable distribution of the deformation area, guaranteeing sufficient elasticity while maintaining the overall strength of the first clamping plate 205.

[0071] During disassembly, the user only needs to apply appropriate pressure to the first retaining protrusion 207 to disengage it from the constraint of the first retaining groove 107, and then pull the first retaining plate 205 out of the first retaining opening 106 in the opposite direction. The entire installation and disassembly process does not require any tools, is simple and quick to operate, and achieves a true quick-release function.

[0072] Continue reading Figure 6 , Figure 7 , Figure 8 and Figure 9 In this embodiment, the second cold shoe holder 300 includes a second locking knob 301, a second threaded post 302, and a second cold shoe plate 304. The second locking knob 301 is sleeved with the second threaded post 302. One end of the second threaded post 302 is provided with a first retaining plate 205, and the other end of the second threaded post 302 is connected to the second cold shoe plate 304. The second retaining plate 305 is provided with a second retaining protrusion 306 on at least one side in its width direction.

[0073] The housing 100 has a second bayonet 108 on one side, and the second bayonet 108 has a second slot 109 that is adapted to the second holding protrusion 306 inside; the second card plate 305 has a second strip opening 307, and the second strip opening 307 extends along the side of the second holding protrusion 306 on the second card plate 305.

[0074] In this embodiment, both the first cold shoe mount 200 and the second cold shoe mount 300 are detachably connected to the housing 100. Specifically, both cold shoe mounts adopt the same quick-release snap-fit ​​structure design, achieving structural uniformity and operational consistency. The structure of the second latch plate 305 is similar to that of the first latch plate 205, but its size and shape are specially designed according to the specific configuration of the second latch 108 on the side of the housing 100 to ensure precise fit with the second latch 108.

[0075] When installing the second cold shoe mount 300, the second locking plate 305 is inserted along the guide surface of the second locking slot 108. During insertion, the second retaining protrusion 306 is elastically deformed by the pressure of the inner wall of the second locking slot 108. After the second locking plate 305 is fully inserted into the designed position, the second retaining protrusion 306 automatically springs into the matching second locking groove 109, forming a stable mechanical lock. The second strip opening 307 provides the necessary deformation space for the second retaining protrusion 306, while the extension design along the side of the second retaining protrusion 306 ensures uniform deformation distribution and overall strength of the locking plate.

[0076] During disassembly, the user can simultaneously press the second retaining protrusion 306 to release it from the constraint of the second retaining slot 109, and then remove the second retaining plate 305 from the second retaining slot 108. This dual quick-release design allows the user to flexibly configure the use of the cold shoe mount according to actual shooting needs. One cold shoe mount can be used alone, or two cold shoe mounts can be installed at the same time to meet shooting needs in different directions.

[0077] By adopting a unified quick-release snap-fit ​​structure, the first cold shoe mount 200 and the second cold shoe mount 300 maintain a high degree of consistency in operation, reducing the user's learning cost, simplifying the production process and maintenance procedures, and improving the practicality and user experience of the entire extended protective shell 10 system.
