Technical Field
[0001] This utility model relates to the field of water-based and underwater equipment technology, specifically to an IP68-rated waterproof remote control. Background Technology
[0002] Surface and underwater equipment is a general term encompassing all kinds of equipment that can operate in water surface and underwater environments and are used for specific operations, monitoring, control and other functions. Its application scenarios involve harsh environments such as underwater operations, robot operation, and marine monitoring. It includes specific types such as underwater operation equipment, underwater robots, and marine monitoring instruments. These types of equipment usually need to cope with complex environmental challenges such as long-term immersion and unstable signal transmission. Therefore, the requirements for the waterproof performance, signal stability and structural reliability of the supporting control device are extremely high. As a supporting control device for underwater and above-water equipment, remote control needs to have good waterproof performance, signal stability and structural reliability. In many application scenarios, such as the operation of underwater work equipment and the control of water entertainment facilities, remote control needs to be able to work stably in the immersion environment. The waterproof rating of traditional remote control is usually IPX4-IPX6. Traditional remote controls are limited by their waterproof rating, meaning they can only withstand small splashes or short-term sprays. If they are submerged for extended periods, moisture can easily seep into the internal components through the casing joints. Once the internal electronic components come into contact with water, they are prone to short circuits and corrosion, leading to remote control malfunction and inability to control the device properly. Therefore, traditional remote controls cannot meet the requirements for long-term submersion. To address these issues, an IP68-rated waterproof remote control is proposed. Utility Model Content
[0003] The purpose of this invention is to provide an IP68-rated waterproof remote control to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: An IP68-rated waterproof remote control includes a lower shell assembly and an upper shell assembly. The lower shell assembly includes a waterproof lower shell, a throttle trigger, a locking pin, and a control board PCBA. A receiving slot is formed in the waterproof lower shell, and a waterproof signal transmitting antenna is installed in the receiving slot. The upper shell assembly includes a waterproof upper shell, a decorative cover, a tightening cover, a battery, a gear lever, and an indicator light. The decorative cover is adapted to the waterproof upper shell and is fitted over the outside of the waterproof upper shell from the top. The top of the waterproof upper shell passes through the decorative cover, and the tightening cover is screwed onto the outside of the top of the waterproof upper shell. The battery, gear lever, and indicator light are installed in the waterproof upper shell. The top of the waterproof lower shell is adapted to the bottom of the waterproof upper shell. The control board PCBA is disposed within a cavity formed between the top of the waterproof lower shell and the bottom of the waterproof upper shell.
[0005] As a further optimization of this utility model, epoxy resin is injected between the receiving groove and the waterproof signal transmitting antenna. The cured layer formed after the epoxy resin is injected completely covers the outer wall of the upper part of the waterproof signal transmitting antenna, and there is no gap between the cured layer and the waterproof lower shell and the waterproof signal transmitting antenna.
[0006] As a further optimization of this utility model, the waterproof lower housing and the throttle trigger are connected by a snap-fit mechanism, the locking pin is inserted into the corresponding lock hole between the throttle trigger and the waterproof lower housing, and an elastic sealing sleeve is provided at the mating point between the locking pin and the lock hole.
[0007] As a further optimization of this utility model, the bottom of the waterproof lower shell is open, and an antenna waterproof cover is screwed onto the bottom of the waterproof lower shell.
[0008] As a further optimization of this utility model, the control PCBA board integrates a surface-mount Hall sensor and a control chip to form a magnetic control circuit module. The gear shift lever and throttle trigger are non-contact triggered by the magnetic control circuit module, with no physical contact gap.
[0009] As a further optimization of this utility model, the indicator light is embedded in a pre-set mounting hole in the upper shell of the waterproof compartment, a waterproof rubber ring is provided at the mating point between the indicator light and the mounting hole, and the indicator light is electrically connected to the control PCBA board through a wire.
[0010] As a further optimization of this utility model, a sealing ring groove is provided between the top of the waterproof lower shell and the bottom of the waterproof upper shell. The two sealing ring grooves are positioned correspondingly and matched in specifications, and a waterproof sealing ring is embedded between the two sealing ring grooves.
[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the combined effect of multiple waterproof structures of the lower and upper shell components effectively prevents water from seeping into the internal cavity. At the same time, the non-contact triggering design of the magnetic control circuit module eliminates the risk of water leakage caused by physical contact gaps, achieving an IP68 waterproof standard. This solves the problem that traditional remote controls cannot be used for long-term immersion in water due to insufficient waterproof rating, meeting the usage needs of more demanding scenarios such as underwater equipment operation and water entertainment facility control, and improving the reliability and service life of the remote control in humid and immersion environments.

The decorative cover 22 is adapted to fit the waterproof upper shell 21. The decorative cover 22 is fitted onto the outside of the waterproof compartment upper shell 21 from the top. The top of the waterproof compartment upper shell 21 passes through the decorative cover 22, and the tightening cover 23 is screwed onto the outside of the top of the waterproof compartment upper shell 21 by threads. The battery 24, the gear lever 25 and the indicator light 26 are installed in the waterproof compartment upper shell 21. The top of the waterproof lower shell 11 is adapted to the bottom of the waterproof compartment upper shell 21. The control board PCBA 14 is disposed in the cavity formed between the top of the waterproof lower shell 11 and the bottom of the waterproof compartment upper shell 21.
[0017] It should be noted that: the lower shell assembly 1 is the operation and control part of the remote control. Its waterproof lower shell 11 is made of high-strength engineering plastic and is integrally injection molded. It has excellent impact resistance and corrosion resistance. The receiving groove 15 is opened inside the waterproof lower shell 11. The waterproof signal transmitting antenna 16 is made of brass core wire with an outer fluororubber insulation layer. Furthermore: The decorative cover 22 in the upper shell assembly 2 is made of aluminum alloy with an anodized surface. After being fitted onto the waterproof chamber upper shell 21, it is fixed by evenly distributed screws. The tightening cover 23 is made of copper, with its internal thread matching the external thread on the top of the waterproof chamber upper shell 21. An O-ring made of nitrile rubber is provided at the threaded connection. After tightening, the top can be sealed. As a further implementation of this solution, epoxy resin 17 is injected between the receiving groove 15 and the waterproof signal transmitting antenna 16. The cured layer formed after the epoxy resin 17 is injected completely covers the outer wall of the upper part of the waterproof signal transmitting antenna 16, and there is no gap between the cured layer and the waterproof lower shell 11 and the waterproof signal transmitting antenna 16. It should be noted that the upper part of the waterproof signal transmitting antenna 16 is sealed by epoxy resin 17. The epoxy resin 17 adopts a vacuum degassing process during the injection process to ensure that the cured layer formed after curing completely covers the outer wall of the upper part of the waterproof signal transmitting antenna 16, and there are no micro gaps between it and the inner wall of the waterproof lower shell 11 and the outer wall of the waterproof signal transmitting antenna 16, thus achieving a thorough waterproof seal. As a further implementation of this solution, the waterproof lower housing 11 and the throttle trigger 12 are snap-fitted together, and the locking pin 13 is inserted into the corresponding lock hole between the throttle trigger 12 and the waterproof lower housing 11. An elastic sealing sleeve is provided at the mating point between the locking pin 13 and the lock hole. It should be noted that the throttle trigger 12 is tightly engaged with the waterproof lower housing 11 through multiple sets of circumferentially arranged buckle structures. The locking pin 13 is chrome-plated and passes through the corresponding lock hole between the throttle trigger 12 and the waterproof lower housing 11. An elastic sealing sleeve made of hydrogenated nitrile rubber is provided at the mating point between the locking pin 13 and the lock hole. The sealing sleeve has a double lip structure, which can form a double seal when the locking pin 13 is inserted. As a further implementation of this solution, the bottom of the waterproof lower shell 11 is open, and the bottom of the waterproof lower shell 11 is screwed with an antenna waterproof cover 18. It should be noted that: the bottom opening of the waterproof lower shell 11 is provided with external threads, and the antenna waterproof cover 18 is made of PA66+GF30 material. Its internal threads are engaged with the external threads at the bottom of the waterproof lower shell 11. The thread engagement is wrapped with polytetrafluoroethylene raw material tape. After tightening, the bottom can be completely sealed, and it is also convenient for the internal components to be maintained later. As a further implementation of this solution, the control board PCBA14 integrates a surface-mount Hall sensor and a control chip to form a magnetic control circuit module. At the mounting positions of the gear shift lever 25 and the throttle trigger 12, non-contact triggering is achieved through the magnetic control circuit module, with no physical contact gap. It should be noted that the control board PCBA14 is a double-sided PCB board with an immersion gold process. The surface-mount Hall sensor integrated on it is model A1324, and the control chip is an STM32F103 series microcontroller. Together they form a magnetic control circuit module. High-temperature resistant neodymium iron boron magnets are respectively set at the mounting positions of the gear lever 25 and the throttle trigger 12. Non-contact triggering is achieved through the magnetic control circuit module, which completely eliminates the physical contact gaps existing in the traditional mechanical contact structure and fundamentally solves the problem of water leakage due to gaps. As a further implementation of this solution, the indicator light 26 is embedded in the pre-set mounting hole of the waterproof housing 21. A waterproof rubber ring is provided at the mating point between the indicator light 26 and the mounting hole, and the indicator light 26 is electrically connected to the control board PCBA14 through a wire. It should be noted that: the indicator light 26 uses high-brightness LED beads, which are embedded in the preset mounting holes of the waterproof housing 21. The mating point between the indicator light 26 and the mounting hole is provided with a waterproof rubber ring made of silicone rubber. Radial sealing is achieved by pressing the indicator light 26. The indicator light 26 is electrically connected to the control board PCBA14 through tinned copper wire. The wires pass through the wire holes of the waterproof housing 21 and are sealed with waterproof potting compound. As a further implementation of this solution, a sealing ring groove 3 is provided between the top of the waterproof lower shell 11 and the bottom of the waterproof upper shell 21. The two sealing ring grooves 3 are positioned correspondingly and matched in specifications, and a waterproof sealing ring 4 is embedded between the two sealing ring grooves 3. It should be noted that the mating surfaces of the top of the waterproof lower shell 11 and the bottom of the waterproof upper shell 21 are precision machined. The sealing ring groove 3 on the mating surface has a rectangular cross-section, and the two sealing ring grooves 3 are precisely aligned. The waterproof sealing ring 4 embedded between the two sealing ring grooves 3 is made of food-grade silicone with a circular cross-section. It has a certain amount of compression during installation to ensure a reliable seal after the upper and lower shells are mated.
[0018] Workflow: During the assembly of the lower housing assembly 1, the waterproof signal transmitting antenna 16 is first installed into the receiving groove 15 using screws. Then, epoxy resin 17 is injected between the receiving groove 15 and the waterproof signal transmitting antenna 16 using a vacuum degassing process until it completely covers the upper outer wall of the waterproof signal transmitting antenna 16. It is left to stand for 24 hours to cure. The control board PCBA 14 is then fixed to the pre-set support on the top of the waterproof lower housing 11 using screws, ensuring that the control board PCBA 14 is placed horizontally without any tilting. The throttle trigger 12 and lock... When assembling the locking pin 13, apply a small amount of silicone grease to the mounting position of the throttle trigger 12 and engage it with the waterproof lower housing 11 through a multi-set snap-fit structure, ensuring that the snap-fit is fully in place. Cover the surface of the locking pin 13 with an elastic sealing sleeve and insert it into the corresponding lock hole between the throttle trigger 12 and the waterproof lower housing 11. After testing that the locking and unlocking functions are smooth, apply waterproof glue to the end of the lock hole. When installing the antenna waterproof cover 18, wrap polytetrafluoroethylene raw material tape around the external thread at the bottom of the waterproof lower housing 11 and tighten the antenna waterproof cover 18 to ensure a reliable seal. When assembling the upper shell assembly 2, first place the battery 24 into the battery compartment inside the waterproof upper shell 21 and fix it with the battery bracket. The waterproof connector at the bottom of the battery compartment is accurately connected to the positive and negative terminals of the battery 24 to ensure no loose connection. When installing the gear shift lever 25, put a fluororubber sealing ring on the rotating shaft of the gear shift lever 25 and install it in the preset shaft hole of the waterproof upper shell 21. Test that the gear shift is smooth and without jamming. Apply sealant to the gap between the shaft hole and the lever. Put a waterproof rubber ring on the mating part of the indicator light 26 and the mounting hole of the waterproof upper shell 21 and install the indicator light 26 in place. Electrically connect it to the control board PCBA14 through the wire. Fill the wire through the wire hole of the waterproof upper shell 21 with waterproof potting compound for sealing. When assembling the decorative cover 22 and the tightening cover 23, put the decorative cover 22 on the outside of the top of the waterproof upper shell 21 and fix it with screws. Put an O-ring on the external thread of the top of the waterproof upper shell 21 and tighten the tightening cover 23 to ensure the top is sealed. When assembling the upper shell assembly 2 and the lower shell assembly 1, first place the waterproof sealing ring 4 in the sealing ring groove 3 at the top of the waterproof lower shell 11 to ensure that the sealing ring is not twisted or offset. Then, align the bottom of the waterproof chamber upper shell 21 of the upper shell assembly 2 with the top of the waterproof lower shell 11, and slowly press down to make the mating surfaces of the upper and lower shells fit together. Fix the two with circumferentially distributed screws, tighten the screws evenly, and ensure that the waterproof sealing ring 4 achieves a certain amount of compression. After the assembly is completed, perform a preliminary sealing test: immerse the entire remote control in clean water and observe for 30 minutes. If no bubbles emerge, the sealing is preliminarily judged to be qualified. Throughout the entire process, the waterproof sealing ring 4, elastic sealing sleeve, waterproof rubber ring, and epoxy resin 17 curing layer work together to prevent moisture from entering the internal cavity. The non-contact triggering design of the magnetic control circuit module eliminates the potential leakage hazards caused by physical contact gaps, fully complying with the IP68 waterproof standard.
