Description

Technical Field

[0001] This invention relates to the field of underwater equipment technology, specifically to an underwater balance switch, an underwater Bluetooth module, and an underwater information acquisition system. Background Technology

[0002] In some underwater equipment such as diving devices, underwater robots, and marine exploration instruments, it is often necessary to press a switch button to perform corresponding operations, such as underwater voice acquisition, underwater image acquisition, and underwater information transmission. Generally, the switch module of these underwater devices is equipped with a deformable waterproof gasket. The button and operating end of the switch module are located on the inner and outer sides of the waterproof gasket, respectively. When the operating end is pressed, it causes the waterproof gasket to deform inward, thus actuating the button and triggering the switch. However, due to water pressure, especially in deep water areas where the pressure is very high, the waterproof gasket will automatically deform inward under the pressure. The water pressure will ultimately act on the button, causing the switch to automatically trigger or even locking the button. This makes it difficult to use these underwater devices that require pressing a switch button in deep water areas. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an underwater balance switch that can prevent underwater equipment from being automatically triggered or even locked by pressing due to water pressure.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: an underwater balancing switch, comprising: The housing has a first waterproof and sealed cavity inside, and a switch trigger terminal is provided in the first waterproof and sealed cavity. The top of the housing has a pressing hole. A waterproof sealing gasket is attached to the housing and seals the press hole; A balance plate, disposed within the first waterproof sealed cavity and rotatably connected to the housing, the balance plate having a first pressing portion, and a balance surface on the side of the balance plate near the waterproof sealing gasket; and A trigger, the first end of which is rotatably connected to the housing, and the second end of which has a second pressing part, the second pressing part and the switch trigger end being located on the upper and lower sides of the first pressing part, respectively; When the trigger is not pressed, the balance surface is parallel to the waterproof sealing gasket. When the trigger is pressed, the second pressing part can press toward the first pressing part, so that the first pressing part presses toward the switch trigger end, thereby triggering the underwater balance switch.

[0005] Compared to existing technologies, the advantages of this invention are as follows: This underwater balance switch features a balance plate between the trigger and the switch trigger end. When the trigger is not pressed, the balance surface of the balance plate is parallel to the waterproof sealing gasket. Therefore, when the underwater balance switch is in deep water, and the waterproof sealing gasket experiences significant water pressure acting on the balance plate, the pressure on all parts of the balance plate's balance surface is uniform. The balance plate maintains a balanced state and does not rotate relative to the housing, thus isolating and protecting the switch trigger end to prevent automatic triggering due to water pressure. Only when the trigger is pressed, under the action of the second pressing part, will the balance plate rotate relative to the housing, thereby pressing the first pressing part towards the switch trigger end and triggering the underwater balance switch. Therefore, this underwater balance switch is suitable for equipment requiring underwater operation buttons, such as diving equipment, underwater robots, and marine exploration instruments, especially for the operation of these devices in deep water areas, preventing automatic triggering or even lock-up upon pressing.

[0006] The aforementioned underwater balance switch includes a housing comprising a base and a sealing cover sealed to the base, wherein the base, the sealing cover, and the waterproof sealing gasket form the first waterproof sealed cavity.

[0007] In the aforementioned underwater balance switch, the lower middle part of the balance plate is rotatably connected to the housing via a first rotating shaft, and the first end of the trigger is rotatably connected to the housing via a second rotating shaft.

[0008] The aforementioned underwater balance switch has a trigger with a raised portion that tilts outwards in a direction away from the housing.

[0009] The aforementioned underwater balance switch has anti-slip textures on the side of the raised portion away from the housing.

[0010] This invention also provides an underwater Bluetooth module, including the aforementioned underwater balance switch. A Bluetooth transmitter board is housed within the housing, and the switch trigger terminal is electrically connected to the Bluetooth transmitter board. This underwater Bluetooth module, employing the aforementioned underwater balance switch, is suitable for wireless control and signal transmission of underwater equipment in deep water.

[0011] The aforementioned underwater Bluetooth module includes a first waterproof shell and a second waterproof shell. The first waterproof sealed cavity is disposed inside the first waterproof shell, and the second waterproof shell is provided with a second waterproof sealed cavity. The Bluetooth transmitter board is disposed inside the second waterproof sealed cavity.

[0012] The aforementioned underwater Bluetooth module, the first waterproof housing includes a switch bottom cover and a switch front cover, the switch front cover being sealed to the switch bottom cover, the switch bottom cover, the switch front cover and the waterproof sealing gasket forming the first waterproof sealed cavity; the second waterproof housing includes a Bluetooth board bottom cover and a Bluetooth board front cover, the Bluetooth board front cover being sealed to the Bluetooth board bottom cover, the Bluetooth board bottom cover and the Bluetooth board front cover forming the second waterproof sealed cavity.

[0013] This invention also provides an underwater information acquisition system, including the aforementioned underwater balance switch. A Bluetooth transmitter board is housed within the housing, and the switch trigger terminal is electrically connected to the Bluetooth transmitter board. The housing also includes a mounting cavity for accommodating a smart terminal. This underwater information acquisition system, employing the aforementioned underwater balance switch, can be used for taking photos or underwater voice communication in deep water.

[0014] This invention also provides an underwater information acquisition system, including the aforementioned underwater Bluetooth module, and a waterproof housing for housing a smart terminal, wherein the underwater Bluetooth module is connected to the outside of the waterproof housing. This underwater information acquisition system, employing the aforementioned underwater Bluetooth module, can be used for wireless control photography or underwater voice communication in deep water.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below: Example 1

[0019] Reference Figure 1 Embodiment 1 of the present invention provides an underwater balance switch 100, including a housing 110, a waterproof sealing gasket 120, a balance plate 130, and a trigger 140. The housing 110 has a first waterproof sealed cavity 111 inside, and a switch trigger end 112 is provided within the first waterproof sealed cavity 111. A pressing hole 113 is provided on the top of the housing 110. The waterproof sealing gasket 120 is connected to the housing 110 and seals the pressing hole 113. The balance plate 130 is disposed within the first waterproof sealed cavity 111 and rotatably connected to the housing 110. The balance plate 130 has a first pressing part 131, and a balance surface 132 is provided on the side of the balance plate 130 near the waterproof sealing gasket 120. The first end of the trigger 140 is rotatably connected to the housing 110, and the second end of the trigger 140 has a second pressing part 141. The second pressing part 141 and the switch trigger end 112 are respectively located on the upper and lower sides of the first pressing part 131. When the trigger 140 is not pressed, the balance surface 132 and the waterproof sealing gasket 120 are parallel to each other; when the trigger 140 is pressed, the second pressing part 141 can press towards the first pressing part 131, so that the first pressing part 131 presses towards the switch trigger end 112, thereby triggering the underwater balance switch 100.

[0020] The underwater balance switch 100 has a balance plate 130 between the trigger 140 and the switch triggering end 112. When the trigger 140 is not pressed, the balance surface 132 of the balance plate 130 is parallel to the waterproof sealing gasket 120. Therefore, when the underwater balance switch 100 is in deep water, the waterproof sealing gasket 120 deforms inward under greater water pressure and acts on the balance plate 130. The pressure on all parts of the balance surface 132 of the balance plate 130 is the same, and the balance plate 130 can maintain a balanced state without rotating relative to the housing 110. This isolates and protects the switch triggering end 112, preventing the underwater balance switch 100 from being automatically triggered by water pressure. Only when the trigger 140 is pressed will the balance plate 130 rotate relative to the housing 110 under the action of the second pressing part 141, thereby pressing the first pressing part 131 toward the switch triggering end 112 and triggering the underwater balance switch 100. Therefore, this underwater balance switch 100 is suitable for equipment requiring underwater operation buttons, such as diving equipment, underwater robots, and marine exploration instruments, especially for the operation of these devices in deep water areas. It can prevent the switches of these devices from automatically triggering or even locking up when pressed. In addition, this underwater balance switch 100 achieves water pressure balance by setting up a balance plate 130, eliminating the need for compensation structures such as springs. This not only simplifies the internal structure of the switch and reduces manufacturing and maintenance costs, but also transmits the original pressing and rebound feel of the switch trigger end 112 to the trigger 140 through the balance plate 130, ultimately providing feedback to the user. This gives the user a more realistic triggering feel. In some scenarios, such as when applied on land, the original "click" sound of the switch trigger end 112 can also be heard, further enhancing the user experience.

[0021] Specifically, the housing 110 includes a base 114 and a sealing cover 115 sealed to the base 114. The base 114, the sealing cover 115, and the waterproof sealing gasket 120 form a first waterproof sealed cavity 111. The waterproof sealing gasket 120 can be fixed to the housing 110 by adhesive bonding. During installation, the sealing cover 115 and the base 114 can also be used to press the waterproof sealing gasket 120 together, thereby improving the sealing effect of the waterproof sealing gasket 120. The lower middle part of the balance plate 130 is rotatably connected to the housing 110 via a first rotating shaft 133, and the first end of the trigger 140 is rotatably connected to the housing 110 via a second rotating shaft 142.

[0022] Furthermore, the trigger 140 has a raised portion 143 that curves outwards away from the housing 110, so that the operator can touch and press the raised portion 143 to trigger the switch operation. Furthermore, the side of the raised portion 143 away from the housing 110 has anti-slip texture 144, which can improve the feel and achieve anti-slip operation underwater.

[0023] It is understood that the underwater balance switch 100 in this invention can be either directly mounted on the main structure of the underwater equipment or be an independent control module. The switch trigger terminal 112 can be a common switch button, and the switch trigger terminal 112 can be connected to the required control circuit board via a wire. Example 2

[0024] Reference Figures 2 to 4 Embodiment 2 of the present invention provides an underwater Bluetooth module 200, including the aforementioned underwater balance switch 100, a Bluetooth transmitter board 210 housed within a housing 110, and a switch trigger terminal 112 electrically connected to the Bluetooth transmitter board 210. This underwater Bluetooth module 200 utilizes the aforementioned underwater balance switch 100 and is suitable for wireless control and signal transmission of underwater equipment in deep water. The Bluetooth transmitter board 210 can be used for Bluetooth communication with other devices. The functions and application scenarios implemented by the underwater Bluetooth module 200 can be achieved by changing the specific circuitry of the Bluetooth transmitter board 210. For example, in some application scenarios, pressing and holding the trigger 140 activates the underwater Bluetooth module 200. Subsequently, each press of the trigger 140 sends a signal outward from the Bluetooth transmitter board 210, enabling information collection, such as taking photos. Pressing and holding the trigger 140 again deactivates the underwater Bluetooth module 200. For example, in some application scenarios, pressing and holding trigger 140 can put the underwater Bluetooth module 200 into working state. At this time, an external device can establish a Bluetooth connection with the underwater Bluetooth module 200, and then continuously send data to the external device in real time. This can be used for underwater voice communication or live shooting. Pressing and holding trigger 140 again can turn the underwater Bluetooth module 200 into a closed state.

[0025] Further, the housing 110 includes a first waterproof housing 220 and a second waterproof housing 230. A first waterproof sealed cavity 111 is disposed within the first waterproof housing 220, which in this case is equivalent to the housing 110 of the underwater balance switch 100. The second waterproof housing 230 has a second waterproof sealed cavity 231, and the Bluetooth transmitter board 210 is disposed within the second waterproof sealed cavity 231. Specifically, the first waterproof housing 220 includes a switch bottom cover 221 and a switch front cover 222. The switch front cover 222 is sealed to the switch bottom cover 221, and the switch bottom cover 221, the switch front cover 222, and the waterproof sealing gasket 120 form the first waterproof sealed cavity 111. The second waterproof housing 230 includes a Bluetooth board bottom cover 232 and a Bluetooth board front cover 233. The Bluetooth board front cover 233 is sealed to the Bluetooth board bottom cover 232, and the Bluetooth board bottom cover 232 and the Bluetooth board front cover 233 form the second waterproof sealed cavity 231.

[0026] In this embodiment, the underwater Bluetooth module 200 is an independent module. It does not need to be directly installed in the underwater equipment. Instead, it can be connected to the underwater equipment over a long distance via a signal transmission line such as a coaxial cable. This allows each module to be waterproofed and enables the Bluetooth module to be closer to the mobile smart terminal, minimizing the attenuation of the Bluetooth signal in the water. Example 3

[0027] Reference Figure 5 and Figure 6 Embodiment 3 of the present invention provides an underwater information acquisition system 300, including the aforementioned underwater balance switch 100. A Bluetooth transmitter board 210 is provided inside a housing 110. The switch trigger terminal 112 is electrically connected to the Bluetooth transmitter board 210 via wires or other structures. The housing 110 also includes an installation cavity 310 for accommodating a smart terminal. This underwater information acquisition system 300, employing the aforementioned underwater balance switch 100, can be used for taking photos or underwater voice communication in deep water.

[0028] Taking underwater photography as an example, the underwater information acquisition system 300 of this embodiment can use an existing underwater photography phone case with trigger photography function as the housing 110 in this embodiment, and replace the switch module in the existing underwater photography phone case with the underwater balance switch 100 of this invention. That is, the structure of the phone case is improved, a first waterproof sealed cavity 111 is opened, and the balance plate 130, trigger 140 and other structures are installed. The underwater balance switch 100 of this invention is installed in the existing underwater photography phone case, thereby enabling pressing to trigger photography in deep water. Example 4

[0029] Embodiment 4 of the present invention provides an underwater information acquisition system 300, including the aforementioned underwater Bluetooth module 200, and a waterproof shell for housing a smart terminal, with the underwater Bluetooth module 200 connected to the outside of the waterproof shell. This underwater information acquisition system 300, employing the aforementioned underwater Bluetooth module 200, can be used for wireless control photography or underwater voice communication in deep water.

[0030] Taking underwater photography as an example again, the underwater information acquisition system 300 in this embodiment can use an existing underwater photography phone case as the waterproof case, and adopt the external underwater Bluetooth module 200 as in embodiment 2. The underwater Bluetooth module 200 is installed on the outside of the case using a clamp or other structure to establish a Bluetooth connection between the underwater Bluetooth module 200 and the mobile phone, thus enabling pressing to trigger photography in deep water. In this embodiment, the waterproof case can adopt a common structure in the prior art, only needing to achieve the waterproof function. The external underwater Bluetooth module 200 avoids having too many holes on the waterproof case, thereby reducing waterproofing costs.
