Description

Technical Field

[0001] This invention relates to the field of diving equipment testing, and more particularly to an underwater testing instrument for diving watches and its testing method. Background Technology

[0002] A dive watch is a timekeeping instrument specifically designed for diving activities. It features high standards of water resistance and luminous display, allowing for use in deep water. Therefore, dive watches undergo functional and water resistance testing before leaving the factory. Underwater testing of dive watches typically involves placing them in a pressurized water tank to simulate an underwater environment. Once the dive watch is placed in the pressurized tank, personnel cannot directly operate the buttons to test their functionality or the sealing effect of the buttons during operation.

[0003] In existing technology, holes are typically drilled directly into the wall of a transparent pressure vessel, a shaft is inserted, and the shaft is pushed out from outside the pressure vessel. The other end of the shaft is used to press a button on a diving gauge. The problems with this method are: 1. Pressure vessel walls are generally curved, making it difficult to implement waterproofing measures after drilling, which can easily damage the integrity of the pressure vessel and affect pressurization performance. 2. It is only applicable to a single pressure vessel; once the pressure vessel is changed, testing becomes impossible, resulting in poor adaptability. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this invention is to solve the technical problem of inconvenient underwater testing of diving watches, and to provide an underwater testing instrument and method for diving watches, which can remotely perform button testing without damaging the pressure tank, making it more convenient to use and more applicable.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a diving watch underwater testing instrument includes a waterproof housing, the upper side of which has a groove for placing the diving watch, and multiple waterproof buttons are provided on the side wall of the groove. A power component is provided inside the waterproof housing, which is electrically connected to the waterproof buttons and can drive the waterproof buttons to move along their own axis. A control circuit board is also provided inside the waterproof housing, which is electrically connected to the power component. The control circuit board integrates a wireless receiving module and a first power supply.

[0006] It also includes a remote control, which includes a housing with a remote control button corresponding to the waterproof button. The housing contains a main control board, and the remote control button is electrically connected to the main control board. The main control board integrates a wireless transmission module and a second power supply.

[0007] The present invention has the following advantages: the diving watch is fixed in the groove, and the movement of the power component can be remotely controlled by a remote control by pressing the button on the side of the diving watch; it does not damage the pressure tank, making it more convenient to use; it can be applied to any pressurized container, making it highly adaptable.

[0008] Furthermore, the power assembly includes a servo bracket, which is fixedly installed inside the waterproof housing. The upper side of the servo bracket has a groove corresponding to the waterproof button, and the length direction of the groove is parallel to the central axis direction of the waterproof button. A slider is slidably installed in the groove, and the upper side of the slider extends out of the groove and abuts against one end of the waterproof button.

[0009] The servo bracket is also equipped with a servo motor corresponding to each waterproof button in the middle. The output shaft of the servo motor is connected to one end of the pull rope, and the other end of the pull rope passes through the servo bracket, extends into the slide groove, and is fixedly connected to the slider.

[0010] The advantages of the above-mentioned further solution are: the slider is moved by the servo motor, and the slider presses the waterproof button, which is simple in structure; the servo motor has high positioning accuracy and fast response speed.

[0011] Furthermore, the waterproof housing includes an upper cover and a bottom cover, with a groove located on the upper side of the upper cover, and the upper cover and the bottom cover are detachably connected.

[0012] The beneficial effect of the above-mentioned further solution is that the waterproof shell is divided into two detachable parts, which facilitates assembly and replacement of internal components.

[0013] Furthermore, a sealing ring is provided at the joint between the upper cover and the bottom cover.

[0014] The beneficial effect of the above-mentioned further solutions is that they can further improve sealing performance.

[0015] Furthermore, the groove is provided with a buckle for securing the diving watch.

[0016] The beneficial effect of the above-mentioned further solution is that it can fix both ends of the diving watch and prevent the diving watch from moving when the test button is pressed.

[0017] Furthermore, a trigger switch is also provided in the groove, and the trigger switch is electrically connected to the first power source.

[0018] The beneficial effects of the above-mentioned further solutions are: triggering the switch to control the on / off state of the circuit, saving energy and extending the battery life when not in operation.

[0019] Furthermore, a waterproof socket is provided on the underside of the bottom cover, and the waterproof socket is electrically connected to the first power source.

[0020] The advantages of the above-mentioned further solutions are that they are waterproof and can be charged and upgraded without opening the cover, making them more convenient to use.

[0021] This invention also discloses a method for testing diving watches, using the aforementioned underwater testing instrument:

[0022] Step 1: Place the diving watch in the recess of the waterproof case and place the underwater testing instrument in a pressure vessel filled with water;

[0023] Step 2: Adjust the pressure value of the pressure vessel to 0-1 MPa to simulate water pressure at different depths;

[0024] Step 3: Use the remote control button to control the power unit to push the waterproof button. Test the function of each button on the diving watch by short press (less than 200ms) and long press (greater than or equal to 200ms). Visually check whether the function of each button is consistent with the expectation.

[0025] Step 4: Remove the diving watch to be tested, wipe off any excess water from the surface, and place it in an oven at 50°C for 5 minutes.

[0026] Step 5: Take out the dive watch and observe whether the inside of the watch is fogged up. If fogged up, it means that the watch buttons are not waterproof. If no fogged up, it means that the watch buttons are waterproof. Attached Figure Description

[0039] The dive watch 15 refers to a special watch used for diving, capable of withstanding water pressure at depths of tens to hundreds of meters. The dive watch 15 has multiple buttons on both sides; in this embodiment, the dive watch 15 has three buttons on one side and two buttons on the other side.

[0040] Example 1

[0041] See Figures 1 to 5A diving watch underwater testing instrument includes a waterproof housing 1. The upper side of the waterproof housing 1 has a groove 2 for placing a diving watch 15. Multiple holes are formed on the side wall of the groove 2, and waterproof buttons 3 are installed in each of the holes. A power component 4 is provided inside the waterproof housing 1. The power component 4 is electrically connected to the waterproof buttons 3 and can drive the waterproof buttons 3 to move along their own axis. A control circuit board 5 is also provided inside the waterproof housing 1. The control circuit board 5 is electrically connected to the power component 4. A wireless receiving module and a first power supply 6 are integrated on the control circuit board 5.

[0042] It also includes a remote control, which includes a housing 7, a remote control button 8 corresponding to the waterproof button 3 on the housing 7, a main control board 9 inside the housing 7, the remote control button 8 being electrically connected to the main control board 9, and the main control board 9 integrating a wireless transmission module and a second power supply 10.

[0043] In this embodiment, the diving watch 15 is inserted into the groove 2, and the waterproof buttons 3 on both sides of the groove 2 correspond one-to-one with the buttons on the diving watch 15. Then, the testing instrument and the diving watch 15 are placed in a transparent pressure tank, which is filled with clean water, and then pressurized to simulate a deep-water environment. The operator holds a remote control outside the pressure tank and presses the corresponding remote control button 8. The remote control button 8 sends an electrical signal to the main control board 9, which transmits the signal through a wireless transmission module. The control circuit board 5 on the other side receives the signal through a wireless receiving module and drives the power component 4 to move. The power component 4 drives the waterproof button 3 to move and press the button, completing the test.

[0044] The groove 2 has multiple holes on its side wall, and a waterproof button 3 is installed in the hole. The waterproof button 3 can seal the hole. One end of the waterproof button 3 protrudes from the side wall of the groove 2, and the other end passes through the hole and extends into the waterproof housing 1. Therefore, the power component 4 can drive the waterproof button 3 to move inside the waterproof housing 1.

[0045] Specifically, the waterproof housing 1 includes an upper cover 101 and a bottom cover 102. The groove 2 is located on the upper side of the upper cover 101 and is integrally formed with the upper cover 101. The upper cover 101 and the bottom cover 102 are connected by screws, and a sealing ring 11 is provided at their joint. This ensures both airtightness and facilitates the assembly and replacement of internal components.

[0046] The groove 2 is provided with a buckle 12 for fixing the diving watch 15. The buckle 12 can be a U-shaped clip made of elastic material, which can be inserted into the two ends of the diving watch 15 for installing the watch strap, and prevent the diving watch 15 from moving left and right when the test button is pressed.

[0047] The groove 2 is also equipped with a trigger switch 13, which is electrically connected to the first power supply 6. The trigger switch 13 is existing technology and can be either a magnetic switch or a micro switch. When the diving watch 15 is placed in the groove 2, pressing the trigger switch 13 connects the internal circuit, supplying power to the first power supply 6. When the diving watch 15 is removed, the trigger switch 13 pops up, disconnecting the internal circuit, saving energy and extending battery life when not in use.

[0048] A waterproof socket 14 is provided on the underside of the bottom cover 102, and the waterproof socket 14 is electrically connected to the first power supply 6. The waterproof socket 14 is a six-pin magnetic waterproof socket, which is not only waterproof, but also allows charging and program upgrades without opening the cover, making it more convenient to use.

[0049] Furthermore, the wireless transmitting and receiving modules can be any type of Bluetooth module, 2.4G non-Bluetooth RF module, infrared transmitting and receiving module, or LoRa spread spectrum module. This solution uses a Bluetooth module, which integrates bidirectional transmission and reception and is suitable for short-range, low-speed transmission.

[0050] This embodiment enables remote control of the power unit 4 to press the button on the side of the diving gauge 15; it does not require damaging the pressure tank, making it more convenient to use; it is applicable to any pressurized container and has strong applicability.

[0051] See Figure 4 The power assembly 4 includes a servo bracket 401, which is fixedly installed inside the waterproof housing 1. The upper side of the servo bracket 401 has a sliding groove 402 corresponding to the waterproof button 3. The length direction of the sliding groove 402 is parallel to the central axis direction of the waterproof button 3. A slider 403 is slidably arranged in the sliding groove 402. The upper side of the slider 403 extends out of the sliding groove 402 and abuts against one end of the waterproof button 3.

[0052] The servo bracket 401 is also provided with a servo 404 corresponding to each of the waterproof buttons 3 in the middle position. The output shaft of the servo 404 is connected to one end of the pull rope 405. The other end of the pull rope 405 passes through the servo bracket 401 and extends into the slide groove 402, and is fixedly connected to the slider 403.

[0053] In this embodiment, six sliding grooves 402 are provided on the upper side of the servo bracket 401, making symmetrical processing more convenient. During use, the appropriate groove can be selected based on the button positions on the diving watch 15. Figure 4 With reference as the frame of reference, on the horizontal projection plane, slider 403 is located on the side of waterproof button 3 away from diving watch 15.

[0054] Specifically, the waterproof button 3 includes a waterproof washer and a button post. The waterproof washer is located at the hole on the side wall of the groove 2 and can seal the hole. The button post slides inside the waterproof washer, with both ends extending from the sides of the waterproof washer, one end pointing towards the groove 2 and the other end extending into the waterproof housing 1. A ring platform is also provided at the end of the button post inside the waterproof housing 1, and a return spring is fitted on the button post. One end of the return spring abuts against the inner side wall of the waterproof housing 1, and the other end abuts against the side of the ring platform facing the groove 2. This return spring can push the button post to slide into the waterproof housing 1.

[0055] Initially, slider 403 is at the end of groove 402 and located on the side of button post away from groove 2. When servo motor 404 is activated, a winding wheel on its output end winds up pull rope 405, pulling slider 403 closer to button post and pushing button post towards groove 2, compressing the return spring. Button post moves towards diving watch 15, pressing the button with its front end. The structure is simple, the servo motor has high positioning accuracy, and the response speed is fast. The duration of button press (short or long press) is determined by the program setting. After pressing, servo motor 404 rotates in the opposite direction back to the initial position, pull rope 405 is released, and the return spring pushes button post into the waterproof housing 1, returning button post to its initial position (button post also pushes slider 403 back to its initial position).

[0056] In addition, one end of the pull rope 405 passes through the servo bracket 401 and extends into the slide groove 402. A linear bearing 406 is also provided at the corresponding position on the side wall of the servo bracket 401, which is a linear guide mechanism to guide the movement of the pull rope 405 and reduce friction.

[0057] Based on this embodiment, another return spring can be provided inside the slide groove 402. One end of the return spring abuts against the side wall of the slide groove 402 near the waterproof button 3, and the other end abuts against the side of the slider 403 facing the waterproof button 3. When the servo motor 404 is de-energized, the return spring can also push the slider 403 to move away from the waterproof button 3 for the next use.

[0058] As a parallel implementation, the power unit 4 can also be replaced with a miniature electric actuator, which is arranged along the central axis of the waterproof button 3, and can push the waterproof button 3 when extended, and has an automatic retraction function.

[0059] Example 2

[0060] This invention also discloses a method for testing diving watches, using the aforementioned underwater testing instrument:

[0061] Step 1: Place the diving watch in the groove 2 of the waterproof housing 1, and place the underwater testing instrument in a water-filled pressure vessel;

[0062] Step 2: Adjust the pressure value of the pressure vessel to 0-1 MPa to simulate water pressure at different depths;

[0063] Step 3: Use remote control button 8 to control power component 4 to push waterproof button 3, and perform short press (less than 200ms) and long press (greater than or equal to 200ms) function tests on each button of the diving watch in sequence; the buttons can call up functions such as backlight on / off, display interface switching, and parameter settings of the diving watch; visually check whether the function of each button during long press or short press is consistent with expectations;

[0064] Step 4: Remove the diving watch to be tested, wipe off any excess water from the surface, and place it in an oven at 50°C for 5 minutes.
