Description

Technical Field

[0001] This invention relates to the field of waterproof equipment technology, and more specifically, to a camera-mounted electronically controlled underwater hull and its manufacturing method. Background Technology

[0002] With the increasing popularity of diving, underwater photography has emerged as a rapidly developing new industry. However, conventional cameras lack waterproof structures and cannot be used directly in underwater environments. Although action cameras have some waterproof capabilities and can shoot directly in shallow water, their diving depth is still very limited. Furthermore, due to the significant difference in optical refractive index between underwater and air, some cameras relying on special optical structures (such as fisheye lenses) cannot produce normal images underwater. Therefore, whether it's a diving camera, action camera, or smartphone, underwater shooting typically requires a dedicated underwater housing to ensure equipment safety and image quality.

[0003] To operate a camera encased in a submersible housing, existing solutions generally employ mechanical button structures. These buttons must simultaneously meet the following requirements: 1. Dynamic sealing: The button itself needs to move to transmit force, which requires the structure to pass through the watertight shell and perform reciprocating or rotating motion.

[0004] 2. Operable under pressure: For button-type structures, there is a pressure difference between the external and internal mechanisms, and the movement needs to eliminate the influence of pressure. This makes the existing waterproof shell structure complex, has high manufacturing cost, and limited reliability.

[0005] 3. In addition, existing action camera submersible housings, due to cost and other factors, only support limited operations such as starting / stopping recording, and cannot achieve complex functions such as mode switching.

[0006] 4. At the same time, most modern cameras have wireless or wired electronic control interfaces, but existing commercial accessories generally do not support use in high water pressure environments, making it difficult to meet the needs of underwater photography.

[0007] 5. Although there are already mobile phone diving cases based on Bluetooth indirect control, there are no related technology reports in the field of professional cameras.

[0008] 6. The closest report, while isolating the camera from the external structure, requires signal transmission through a series of complex circuits that need to be specifically designed, and necessitates a double-layered watertight compartment, resulting in low practical value.

[0009] 7. For pressure balancing of underwater devices, in addition to mechanical structures, dielectric liquids or paste filling methods can also be used. This method has not yet been applied to complex circuit structures. However, in the field of immersion liquid cooling, insulating dielectric liquids have been widely proven not to affect the operation of complex circuits. Summary of the Invention

[0010] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide an electrically controlled underwater hull for cameras and a method for manufacturing the same.

[0011] To achieve the above and other related objectives, the present invention provides a camera-mounted electric control submersible hull, comprising: A watertight housing with an openable cover for sealing, and a photographic device is placed inside the watertight housing; A control mechanism, which is connected to the photographing device wirelessly or via a signal transmission cable; A handheld lever is mounted on the bottom of the watertight housing, and the control mechanism is mounted on the handheld lever.

[0012] In one embodiment of the present invention, the watertight housing is provided with a transparent window for the photographing device to take pictures.

[0013] In one embodiment of the present invention, the control mechanism includes: A plastic housing is mounted on the handgrip. A flexible film is mounted on the plastic housing; A wireless remote control, which is encapsulated in a cavity consisting of the flexible film and the plastic shell; The cavity is completely filled with the dielectric liquid.

[0014] In one embodiment of the present invention, the control mechanism further includes: An inlet port, which is installed on one side of the plastic housing, is used to inject the dielectric liquid into the cavity; A stopper structure that is sealed to the inlet.

[0015] In one embodiment of the present invention, the handheld stick is a telescopic handheld stick.

[0016] In one embodiment of the present invention, it further includes: A flexible antenna extension line, one end of which is connected to the wireless remote controller in the control mechanism, and the other end of which is connected to the adhesive antenna; An adhesive antenna is mounted on the watertight housing.

[0017] In one embodiment of the present invention, the watertight shell and the hatch are made of transparent polycarbonate material by injection molding.

[0018] In one embodiment of the present invention, the watertight shell and the hatch are connected by a hinge structure to achieve an openable and closed seal.

[0019] In one embodiment of the present invention, it further includes: An annular groove is provided on the edge of the hatch for placing a sealing ring; A snap-fit ​​structure is installed at the end of the hatch cover; A limiting and fixing block is disposed in the gap between the watertight housing and the photographing device, and the photographing device is stably fixed by forming a tight fit with the frame of the watertight housing.

[0020] This invention also includes a method for manufacturing an electro-optical control submersible housing for cameras, applied to the aforementioned electro-optical control submersible housing for cameras, the method comprising: S1. The watertight shell is manufactured by one or a combination of injection molding, CNC turning, and 3D printing, and the material used to manufacture the watertight shell is one of glass, metal, and fiber composite materials. S2. The watertight housing transmits control commands in a non-contact manner, or transmits control signals to the imaging device through the signal transmission cable; S3. An independent watertight compartment is provided outside the watertight shell or at the connection point with the watertight shell for installing the control mechanism; S4. Place the wireless remote control of the camera device into the cavity and fill the cavity completely by injecting dielectric liquid to remove all air. One side of the cavity is set as a flexible film. The flexible film is fixed to the watertight shell by one or a combination of adhesive, mechanical fixation, integral molding, and welding.

[0021] As described above, the electro-optical control underwater hull for cameras and its manufacturing method of the present invention have the following beneficial effects: This invention provides a camera-mounted electro-optical control submersible housing, which reduces processing requirements and improves sealing reliability. Compared to traditional submersible housings using mechanical buttons, this invention significantly simplifies the manufacturing process and enhances sealing reliability. Mechanical submersible housings require through holes at the corresponding positions of each camera button and the configuration of sealing rings, mechanical transmission rods, and limiting components to achieve the triggering function, resulting in cumbersome manufacturing processes and higher costs and assembly times. When using wireless control, this invention eliminates the need for any mechanical openings in the submersible housing; even with wired control, only a single cable pass-through hole is required, and the signal cable does not move mechanically during use, making the sealing design simpler and more reliable, fundamentally reducing the potential risk of water leakage.

[0022] This invention provides an electrically controlled underwater housing for cameras, enhancing the overall design freedom of both the camera and the housing. This invention significantly optimizes the structural arrangement of the camera and housing, making it particularly suitable for compact products such as panoramic cameras (e.g., DJI IOSMO 360). These cameras require large lens covers to accommodate the light intake of fisheye lenses. However, these large lens covers often cover the power switches and recording buttons on the camera body, making the mechanical button layout difficult and resulting in poor operability, thus hindering the development of conventional underwater housings for such products. For larger camera underwater housings, additional space needs to be reserved to accommodate the mechanical button structure, increasing both size and buoyancy. This invention eliminates the mechanical buttons, allowing for free optimization of the external structure, making the housing more compact and buoyancy easier to control.

[0023] This invention provides an electro-optical control submersible housing for cameras, improving compatibility between different camera models. Based on wireless or wired electronic control, and employing publicly available or commercial communication protocols (such as wireless networks and Bluetooth), different models can be adapted simply by switching the controller's software layer, without requiring mechanical redesign of the housing. Furthermore, since most cameras share a high degree of similarity in size (e.g., between action cameras and digital cameras), the housing can be designed as a universal, pressure-resistant body, adapting to different models simply by replacing the internal non-pressure-resistant camera mounting module. This module can be manufactured using low-cost 3D printing, further enhancing versatility and reducing production costs.

[0024] This invention provides a camera-mounted electro-hydraulic control submersible housing, shortening the development cycle of the electronic control system. Utilizing an immersion-type pressure-resistant method, it eliminates the need for a newly designed controller. The immersion-type pressure-resistant design allows commercially available camera remote controls lacking pressure resistance to be directly encapsulated in a semi-flexible control module. Watertightness and pressure resistance are achieved by filling with dielectric fluid, eliminating the need to develop dedicated pressure-resistant electronic components. This solution significantly shortens the electronic control design cycle, reduces the development difficulty and cost of the electronic control system, and improves reliability, making it suitable for various diving depths and environments.

[0038] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

However, the technical solutions claimed in this disclosure can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0039] Please see Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the structure of a camera-mounted electric control submersible hull according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the control mechanism of a camera-mounted electric control submersible housing according to an embodiment of the present invention. The present invention provides a camera-mounted electric control submersible housing, comprising: a watertight housing 1 with an openable and closable hatch 2 for sealing, wherein a photographing device is placed inside the watertight housing 1; a control mechanism 3 connected to the photographing device wirelessly or via a signal transmission cable 4; and a handheld rod 5 mounted on the bottom of the watertight housing 1, wherein the control mechanism 3 is mounted on the handheld rod 5.

[0040] Specifically, the photographing device can be, but is not limited to, a camera, a mobile phone, or a tablet computer. For example, the photographing device is a camera, which is placed inside the watertight housing 1 and sealed by the hatch 2. The housing remains completely watertight but does not block wireless radio frequency signals, allowing the camera to still receive control commands from the control mechanism wirelessly. Since no mechanical buttons are provided, the housing does not require additional openings, thereby improving sealing reliability and reducing manufacturing complexity.

[0041] Furthermore, the watertight housing 1 is provided with a transparent window for the photographing device to take pictures.

[0042] Specifically, the control mechanism 3 includes: a plastic housing 7 mounted on the handheld stick 5; a flexible film 6 mounted on the plastic housing 7; a wireless remote controller 9 encapsulated in a cavity formed by the flexible film 6 and the plastic housing 7; the cavity is completely filled with the dielectric liquid 8. An inlet 10 is mounted on one side of the plastic housing 7, and the inlet 10 is used to inject the dielectric liquid 8 into the cavity; a stopper structure is sealed to the inlet 10.

[0043] Specifically, the wireless remote controller 9 can be a camera remote controller, which is encapsulated in a cavity consisting of a flexible film 6 and a plastic shell 7. This cavity is completely filled with a dielectric liquid 8 and excludes all air.

[0044] The dielectric liquid 8 has near-incompressibility, while the components inside the remote control are solid. Therefore, in an underwater environment, external water pressure can be directly transmitted to the liquid inside the cavity through the flexible membrane 6, so that the pressure inside the cavity is automatically balanced with the external water pressure, thereby avoiding the cavity structure from bearing differential pressure.

[0045] Therefore, even though the remote control is a non-pressure-resistant electronic product, it can work safely in deep water environments.

[0046] Furthermore, the flexible film 6 is elastic, and the operator can press the film from the outside to directly transmit the force to the remote control buttons inside the cavity, enabling the camera to perform operations such as shooting, recording, and switching modes.

[0047] In close-range use scenarios, the remote control's wireless signal can penetrate several centimeters of water to reach the camera, thereby enabling telemetry control.

[0048] Furthermore, if the camera itself does not have wireless control capabilities, or if a greater distance needs to be placed between the control mechanism and the camera, wired control can be achieved through the signal transmission cable 4. The cable only bears signal transmission and does not withstand mechanical movement, therefore its sealed design is simple and reliable.

[0049] Specifically, the camera-mounted electric control submersible hull of the present invention further includes: The annular groove 14 is provided on the edge of the hatch cover 2 for placing the sealing ring; the snap-fit ​​structure 15 is installed at the end of the hatch cover 2; the limiting fixing block 16 is provided in the gap between the watertight housing 1 and the imaging device, and the imaging device is stably fixed by forming a tight fit with the frame of the watertight housing 1.

[0050] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a camera-mounted electric control submersible hull according to an embodiment of the present invention.

[0051] Embodiment 1 of the present invention: an electrically controlled underwater hull for a panoramic camera.

[0052] Watertight shell structure: The camera watertight housing 11 and the hatch 12 are made of transparent polycarbonate (PC) material by injection molding. The two are connected by a hinge structure 13 to achieve an openable and closed seal.

[0053] The edge of the hatch 12 has an annular groove 14 for placing a sealing ring. A snap-fit ​​structure 15 (any existing snap-fit ​​technology can be used) is provided at the end of the hatch 12 to ensure reliable closure and quick operation of the housing. To keep the camera fixed and stable inside the housing, this embodiment uses 3D printing to manufacture a limiting and fixing block 16, which is placed in the gap between the housing and the camera, forming a tight fit with the housing frame to stably fix the camera. The watertight housing body 11 is connected to the handheld lever 18 for underwater gripping and operation by the diver. The control device 17 is fixed to the handheld lever 18 for electronic control of the camera. The handheld lever 18 can be manufactured using any existing method, such as injection molding, aluminum alloy machining, carbon fiber molding, etc.

[0054] Please see Figure 4 , Figure 4 This is a schematic diagram of the control mechanism for a camera-mounted electric-controlled underwater hull according to an embodiment of the present invention. The control device of the present invention includes: A flexible, waterproof membrane 19, a wireless remote control 20, a plastic housing 22, and a plug structure 21 are assembled. The wireless remote control 20 is fixed within the cavity formed by the plastic housing 22 via a detachable mechanism (such as an adhesive label) and will not move. The flexible membrane 19 and the plastic housing 22 are bonded together with peelable adhesive, maintaining a sealed isolation during use while still allowing for easy disassembly, replacement of the remote control, or internal inspection during maintenance. After the flexible membrane 19, wireless remote control 20, and plastic housing 22 are assembled, dielectric liquid is injected into the cavity through the inlet 23 until it is completely filled and all air bubbles are expelled, making the cavity approximately "incompressible." This allows for automatic pressure balance under water pressure, ensuring the remote control can still function normally in deep water environments. After filling, the plug structure 21 is sealed to the inlet 23, completely isolating the entire cavity from the outside environment.

[0055] Specifically, the camera-mounted electric control submersible housing of the present invention further includes: one end of a flexible antenna extension line 25 is connected to a wireless remote controller 9 in the control mechanism 3, and the other end of the flexible antenna extension line 25 is connected to an adhesive antenna 24; the adhesive antenna 24 is disposed on the watertight housing 1.

[0056] Please see Figure 5 , Figure 5This is a schematic diagram of the structure of a camera-mounted electric control submersible hull according to an embodiment of the present invention.

[0057] Embodiment 2 of the present invention: an electrically controlled submersible hull that cooperates with a retractable handheld stick.

[0058] Based on Embodiment 1, the handheld stick 18 is replaced with a retractable handheld stick 26, which is manufactured using existing related technologies. Simultaneously, a flexible antenna extension cable 25 is led out from the remote control, its length sufficient to connect the control device 17 and the adhesive antenna 24 when the retractable handheld stick 26 is fully extended. When the retractable handheld stick 26 is extended, the signal can be transmitted to the adhesive antenna 24 through the less attenuated flexible antenna extension cable 25, thereby enabling control and avoiding the problem of strong signal attenuation in water, allowing the user to still operate the camera in this situation.

[0059] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of a camera-mounted electric control submersible hull according to an embodiment of the present invention.

[0060] Embodiment 3 of the present invention: Electro-optical control submersible hull for digital cameras This embodiment provides an electronically controlled underwater hull suitable for digital cameras. Its overall structure is similar to that of Embodiment 1, but it has been adjusted accordingly based on the characteristics of digital cameras.

[0061] Digital camera diving case main structure: The camera submersible housing 29 in this embodiment can be manufactured using CNC machining, 3D printing, or other existing manufacturing technologies. Because this invention employs electronic control, the housing does not require mechanical buttons or their associated mechanical transmission mechanisms, thereby reducing processing difficulty and manufacturing costs.

[0062] The rear cover 27 of the diving hull is made of transparent polycarbonate material in one piece. Since there is no need to set up mechanical buttons, the rear cover can be completely flat and transparent, eliminating the need for a separate viewing window component. This not only reduces manufacturing costs but also allows divers to directly observe the internal sealing status.

[0063] Optionally, this embodiment may be configured with a power / signal cable 28 for supplying power to control signals and data, or for wired transmission of control signals and data when wireless is unavailable. The rear cover 27 and the housing 29 are locked and sealed by a mechanical structure, such as screws, snap-fit ​​locking rings, or other existing watertight connection structures.

[0064] In some scenarios, an electronic actuator can be further installed inside the housing 29 to indirectly control functions that the camera cannot perform through its own system, such as optical focusing, physical dials, or power switches, in order to improve compatibility.

[0065] Please see Figure 7 , Figure 7 This is a schematic diagram of the structure of a camera-mounted electric control submersible hull according to an embodiment of the present invention.

[0066] Embodiment 4 of the present invention: Submersible housing for electronic control and electronic display of digital cameras This embodiment further expands the control functions based on embodiment 3, providing a digital camera diving hull that simultaneously possesses both electronic control and electronic display capabilities, thereby improving the underwater observation and operation experience for divers.

[0067] Expanded display functionality of the control device: In this embodiment, in addition to sending camera control commands, the controller 30 also integrates a display module, such as an LCD screen or an OLED display. This display module can display the viewfinder image, thereby solving the problems of small screen size, insufficient brightness, and limited viewing angle of digital cameras in underwater environments.

[0068] Multiplexing of signal and power lines: The power / signal cable 28 not only supplies power to the control mechanism 3, but can also be configured as a multi-core or multi-channel structure to support the transmission of images, status information, or preview signals. Through this cable, the display module on the controller can obtain information output from the camera in real time, enabling underwater preview or status monitoring. By configuring a larger, brighter, and more easily observable display module outside the diving hull, this embodiment significantly enhances the diver's operating experience.

[0069] Expanded material options: Due to the presence of the additional display, the transparent back cover 27 can be replaced with other high-strength opaque materials such as metal, carbon fiber composites, etc.

[0070] Specifically, the flexible outer shell of the plastic casing 7 and the underwater hull for submersible pressure balance to achieve underwater operation can also use traditional mechanical buttons and a rigid casing. The separate control mechanism 3 can also be replaced with a diving watch, mobile phone, or other devices.

[0071] Another aspect of the present invention provides a method for manufacturing an electrically controlled submersible hull, the method comprising the following steps or features: S1. The watertight shell 1 is manufactured by one or a combination of injection molding, CNC turning, and 3D printing. The material used to manufacture the watertight shell 1 is one of glass, metal, and fiber composite materials. S2. The watertight housing 1 transmits control commands in a non-contact manner, or transmits control signals to the imaging device through the signal transmission cable 4; S3. An independent watertight compartment is provided outside the watertight shell 1 or at the connection point with the watertight shell 1 for installing the control mechanism 3; S4. Place the wireless remote control 9 of the camera device into the cavity and fill the cavity completely by injecting dielectric liquid 8 to remove all air. One side of the cavity is set with a flexible film 6. The flexible film 6 is fixed to the watertight shell 1 by one or a combination of adhesive, mechanical fixation, integral molding, and welding.

[0072] Specifically, a method for manufacturing an electrically controlled submersible hull according to the present invention includes: (1) Manufacturing of the watertight shell The watertight housing can be manufactured using injection molding, CNC turning, 3D printing, or a combination of these methods. The resulting housing, once housing the camera, achieves pressure resistance and watertightness, while its transparent window does not affect the camera's normal image quality. This watertight housing does not require mechanical keyholes; only the overall pressure-resistant sealing performance of the housing needs to be ensured.

[0073] (2) Control signal penetration method This watertight housing allows control commands to be transmitted non-contactly (including radio signals, acoustic signals, optical signals, etc.) or through signal cables that do not involve mechanical moving parts. This method avoids the use of mechanical buttons, eliminating the need for complex dynamic sealing structures in the housing.

[0074] (3) Improve the pressure resistance and simplify the manufacturing of the watertight shell. By eliminating mechanical buttons and their associated structures, the pressure resistance and sealing reliability of the housing can be significantly improved, while reducing processing costs and assembly difficulty. The housing only needs to be sealed as a whole, avoiding the complex components such as tiny through holes, button rods, and sealing rings required by mechanical buttons.

[0075] (4) Construction of independent watertight compartments To enable camera control, this method incorporates a separate watertight compartment outside the housing or at its connection point with the housing for mounting the control device. This compartment provides waterproofing and pressure resistance, and is responsible for receiving operating commands from the diver and converting them into control signals that the camera can recognize.

[0076] (5) Pressure-resistant encapsulation of the control device A commercial remote control for a camera is placed inside the compartment, which is then completely filled with a dielectric fluid, expelling all air. One side of the compartment is fitted with a flexible, waterproof membrane to balance external water pressure and allow for finger pressure. Once filled with the dielectric fluid, the internal pressure of the compartment automatically balances with water depth, enabling commercial remote controls that are not pressure-resistant or homemade remote controls that are not capable of diving to function properly in deep water. The flexible, waterproof membrane is secured to the housing with adhesive.

[0077] In summary, the electro-optical control submersible housing for cameras of this invention reduces processing requirements and improves sealing reliability. Compared to traditional submersible housings using mechanical buttons, this invention significantly simplifies the manufacturing process and enhances sealing reliability. Mechanical submersible housings require through holes at the corresponding positions of each camera button and the configuration of sealing rings, mechanical transmission rods, and limiting components to achieve the triggering function, resulting in cumbersome manufacturing processes and higher costs and assembly times. When using wireless control, this invention eliminates the need for any mechanical openings in the submersible housing; even with wired control, only a single wire passage hole is required, and the signal line does not move mechanically during use, making the sealing design simpler and more reliable, fundamentally reducing the potential risk of water leakage.

[0078] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
