Description

Technical Field

[0001] This invention relates to the field of electric vehicle water and electricity control technology, and in particular to an intelligent integrated water and electricity control system for RVs. Background Technology

[0002] With the popularization of new energy technologies, fuel-powered RVs are gradually being replaced by new energy RVs. To achieve energy-saving management of RV water and electricity, intelligent control of the water system is necessary. RV water supply is divided into two modes: self-supply from the onboard fresh water tank and external water source at the campsite. Currently, RV water systems generally use multiple sets of manual valves to switch between the two water sources, which has the following drawbacks: Manually operating valves to switch water circuits is a cumbersome process; manual operation is prone to errors, which can cause cross-contamination and backflow between the two water sources. The water pipes lack an automatic drainage structure, making it easy for water to accumulate inside. In low-temperature environments, the accumulated water can freeze and crack the pipes, and long-term water accumulation can also breed impurities and bacteria. The lack of an automatic water supply mode prompt structure makes it impossible for users to intuitively identify the current water supply circuit, resulting in a poor user experience. Without automatic sensing and switching logic, even with an external water source connected, the system will maintain its original operating state unless manually switched on the valves and control loops. It lacks "plug-and-play" adaptive capabilities and struggles to meet the diverse intelligent usage needs of RVs across various scenarios. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problems of existing RV water circuit switching being cumbersome, prone to backflow and leakage, lack of antifreeze and drainage of pipelines, and lack of automatic mode perception and prompting, and to provide an intelligent water and electricity integrated control system for RVs, which completely solves the defects mentioned in the background technology.

[0004] This invention is achieved through the following technical solution: This invention proposes an intelligent water and electricity integrated control system for RVs, including a valve body. A fixed bracket is installed on the outer side of the valve body. The left end of the valve body is connected to a drain hole, and the right end of the valve body is connected to a valve body sealing cover. A clean water tank interface is connected to the valve body sealing cover. A water terminal interface and an external water source interface are connected to the bottom side of the valve body. A self-supply mechanism is connected to the clean water tank interface. A valve core control switching mechanism is set inside the valve body, and the valve core control switching mechanism is sealed and cooperates with the drain hole and the clean water tank interface. The valve core control switching mechanism includes an isolation plate, which is fixedly installed inside the valve body and located between the water terminal interface and the external water source interface; a first hexagonal rod is fixedly installed on the isolation plate, a second hexagonal rod is slidably mounted on the first hexagonal rod, and a cam is installed on the second hexagonal rod; two through holes are opened on the top side of the valve body, and circuit switches are installed inside the through holes. The two sets of circuit switches are used to control the operation of the self-water supply mechanism and to indicate the status of the external water source, respectively; the cam is squeezed and matched with the two sets of circuit switches to realize the synchronous linkage of water circuit switching and circuit opening and closing; a pressure sensor is also provided on the top of the valve body, which is used to collect pipeline water pressure signals and link the start and stop of the self-water supply mechanism.

[0005] Preferably, the self-supplying water mechanism includes a clean water tank with a water inlet on the top; a water pump is installed on the top of the clean water tank, with a pumping pipe connecting the pump inlet to the clean water tank and a water supply pipe connecting the pump outlet to the clean water tank interface; the water pump is electrically connected to the circuit switch closest to the water terminal interface in one of the two sets of circuit switches, and the water pump automatically starts and stops in the self-supplying water mode by relying on the linkage of the circuit switches.

[0006] Preferably, the circuit switch includes a sealing cylinder, which is fixedly installed in the through hole of the valve body; a sealing piston is slidably assembled inside the sealing cylinder; an insulating rod is fixed to the outside of the sealing piston, extending outward from the sealing cylinder and fixing an arc-shaped ball, with the insulating rod and the sealing cylinder in a sealed sliding connection; a conductive bridge is fixed to the top of the sealing piston, and two sets of conductive blocks are fixed inside the sealing cylinder, with the conductive blocks and the conductive bridge being electrically compatible; a tension spring is installed between the bottom of the sealing piston and the inner wall of the sealing cylinder, and the tension spring is sleeved on the outside of the insulating rod; an indicator light is set on the outside of the sealing cylinder. By relying on the cam to press the arc-shaped ball, the sealing piston moves vertically, controlling the contact / separation of the conductive bridge and the conductive blocks, completing the switching of the water pump power supply circuit and the external water source indication circuit. The tension spring provides a reset force for the sealing piston, and the circuit switch automatically disconnects when there is no external pressure.

[0007] Preferably, six connecting rods are fixedly installed on the outer side of the second hexagonal rod, and sealing posts are fixedly installed at the outer ends of the six connecting rods; six external water connection holes are opened on the isolation plate, and the sealing posts are sealed and plugged into the corresponding external water connection holes; the isolation plate has an annular pressure-bearing sealing surface on the side facing the external water source interface, and the water pressure of the external water source can act on the pressure-bearing sealing surface to form an axial pressure difference, driving the second hexagonal rod to slide axially. Relying on the synchronous linkage of the six sets of sealing posts, the opening and closing of the external water connection holes are synchronously controlled to realize the physical isolation and switching of the two water paths.

[0008] Preferably, a first spring cavity is formed at the end of the first hexagonal rod near the second hexagonal rod, and the second hexagonal rod is slidably connected to the inner wall of the first spring cavity in a sealed manner; a first spring is fixedly installed inside the first spring cavity, and the two ends of the first spring are respectively connected to the bottom of the first spring cavity groove and the end of the second hexagonal rod. The first spring provides a normal return force, and after the water pressure of the external water source disappears, it pulls the second hexagonal rod to automatically reset and switch back to the self-supply mode.

[0009] Preferably, a connecting seat is fixedly installed at the end of the second hexagonal rod away from the isolation plate. The connecting seat has a third spring cavity, and the end of the second hexagonal rod is slidably connected to the inner wall of the third spring cavity. A third spring is installed inside the third spring cavity. A clean water sealing plug is fixed on the side of the connecting seat near the clean water tank interface, and the clean water sealing plug is adapted to the clean water tank interface. Under normal conditions, the clean water sealing plug is separated from the clean water tank interface and does not block the clean water tank interface. The third spring provides elastic pre-tightening force, which allows the clean water sealing plug to adaptively press against the clean water tank interface in the external water source mode, ensuring a stable seal and preventing cross-flow and backflow between the two water sources.

[0010] Preferably, a connecting rod is fixedly installed at the end of the first hexagonal rod away from the isolation plate. The connecting rod has a second spring cavity, and the end of the first hexagonal rod is slidably connected to the inner wall of the second spring cavity. A second spring is installed inside the second spring cavity. A drain sealing plug is fixed at the end of the connecting rod away from the first hexagonal rod, and the drain sealing plug is in a sealing fit with the drain hole. The second spring provides a normal sealing pre-tightening force for the drain sealing plug, so that the drain hole is normally closed. When manually pressed, the spring can be compressed to open the drain hole, realizing the drainage of water accumulated in the pipeline.

[0011] Preferably, a pressing handle is fixedly installed on the outer end of the venting sealing plug, and the outer end of the pressing handle passes through the venting hole and is fixed with a gripping head; the fixing bracket includes a bracket mounting plate with several mounting holes, two fixing plates are fixed on the inner side of the bracket mounting plate, and slots are formed on the fixing plates. The fixing bracket is used for overall assembly and limiting of the valve body, and the pressing handle is used for manually venting water from the pipeline.

[0012] Compared with the prior art, the present invention provides an intelligent water and electricity integrated control system for RVs, which has the following beneficial effects: 1. Innovative passive water pressure self-driven switching: It abandons the manual valve control and electric control actuator drive scheme, and relies on the external water pressure to form a pressure difference on the pressure-bearing sealing surface of the isolation plate to automatically drive the valve core to complete the dual water source switching; no additional power supply or control program is required, which is suitable for the complex power supply conditions of RVs and has strong operational stability.

[0013] 2. Integrated synchronous linkage of water and electrical circuits: The mechanical displacement of the valve core synchronously drives the cam to switch two sets of circuit switches. The water circuit switching is completed synchronously, and the water pump is de-energized and the clean water tank interface is sealed for double physical isolation. The cam stroke is set with a staggered structure to avoid the condition that the cam transition position simultaneously conducts two sets of switches. The mechanical action and electrical logic are precisely synchronized to achieve unmanned adaptive control. From the structural level, water source cross-contamination and backflow are avoided, and the dual water source is automatically switched.

[0014] 3. Multi-spring adaptive composite seal: The first, second and third springs are set up to match the sealing structure, which respectively realizes the automatic reset of the valve core, the normal sealing of the vent, and the adaptive compression sealing of the clean water interface; it can adapt to the working conditions of pipeline water pressure fluctuation, and bidirectionally blocks the risk of crossflow and backflow between the clean water tank and the external water source, significantly improving the sealing reliability.

[0015] 4. Six-hole synchronous isolation anti-water leakage structure: Six sets of sealing columns move axially synchronously with the valve core, and isolate the vehicle water circuit and the external water circuit at multiple points synchronously. This replaces the traditional single-hole sealing structure, and the water circuit isolation is complete and synchronous, which greatly reduces the probability of water leakage and water leakage caused by valve switching lag.

[0016] 5. Integrated multi-functional valve body: The dual water source switching, electromechanical linkage control, manual antifreeze drainage of pipelines, and anti-vibration installation of equipment are integrated into a single valve body, replacing the traditional split valve group. The compact size is suitable for the small assembly space of RVs; the mechanical trigger circuit switch is combined with the sealed waterproof structure, which is suitable for the humid and bumpy vibration environment of RVs. The structure is simple and durable.

[0017] This invention adopts passive water pressure self-driven switching, combined with electromechanical integration, multi-spring adaptive sealing, and a six-hole synchronous partition structure to achieve fully automatic switching between dual water sources in RVs, preventing cross-contamination, preventing pipe freezing and draining, eliminating the need for electrical control, and featuring high integration and strong stability.

[0020] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0021] Example like Figures 1-18 As shown in the figure, an embodiment of the present invention proposes an intelligent water and electricity integrated control system for RVs, including a valve body 1. A fixing bracket 2 is fixedly installed on the outer side of the valve body 1. A drain hole 13 is connected to the left end of the valve body 1, and a valve body sealing cover 10 is connected to the right end of the valve body 1. A clean water tank interface 14 is connected to the outer side of the valve body sealing cover 10. A water terminal interface 11 and an external water source interface 12 are respectively connected to the bottom side of the valve body 1. A pressure sensor 5 is installed on the top of the valve body 1. The pressure sensor 5 is used to collect the water pressure signal inside the valve body and to control the start and stop of the self-water supply mechanism. The clean water tank interface 14 is connected to the self-water supply mechanism. A valve core control switching mechanism 6 is fixedly installed inside the valve body 1. The valve core control switching mechanism 6 is sealed and fitted with the drain hole 13 and the clean water tank interface 14 respectively.

[0022] In this invention, the valve core control switching mechanism 6 includes an isolation plate 61, which is fixedly installed inside the valve body 1 and positioned between the water terminal interface 11 and the external water source interface 12. The isolation plate 61 has an annular pressure-bearing sealing surface on the side facing the external water source interface 12. After the external water source enters, a sealed pressure-bearing cavity is formed on the left side of the isolation plate, generating an axial pressure difference to drive the valve core. A first hexagonal rod 62 is fixedly mounted on the isolation plate 61, and a second hexagonal rod 65 is slidably mounted on the first hexagonal rod 62. A cam 68 is fixedly mounted on the outer side of the second hexagonal rod 65. The cam 68 has a staggered stroke structure, allowing it to press only one set of circuit switches individually, without simultaneously connecting two sets of switch circuits. Two sets of through holes are opened on the top side of the valve body 1, each containing a circuit switch 4. The two sets of circuit switches 4 are used to control the start / stop of the self-supply mechanism and to indicate the status of the external water source, respectively. The cam 68 is fitted with the two sets of circuit switches 4 to achieve circuit switching.

[0023] The system uses valve body 1 as the integrated carrier, integrating water circuit switching, water pressure self-adaptation, circuit linkage control, and dual water source automatic switching functions. It can automatically and seamlessly switch between the RV's self-supply mode and the external water supply mode depending on whether an external water source is connected, without the need for manual valve switching. This achieves intelligent adaptive control of the RV's water and electricity system. It also has functions such as pipeline dredging, status indicator light prompts, and water pressure monitoring and protection, making it suitable for use in various scenarios such as RV driving, parking, and campsite external water connection.

[0024] In this invention, the self-supplying water mechanism includes a clean water tank 3, a water inlet 31 on the top of the clean water tank 3, a water pump 32 fixedly installed on the top of the clean water tank 3, a water inlet pipe 321 connected to the clean water tank 3, and a water supply pipe 33 connected to the clean water tank interface 14; the water pump 32 is electrically connected to the set of two sets of circuit switches 4 closest to the water terminal interface 11, so as to realize the linkage control of the power on and off of the water pump 32.

[0025] The self-supply mechanism is the core water supply structure when the RV is parked without an external water source. The water inlet 31 is used to replenish and store water in the fresh water tank 3. The water pump 32 draws fresh water from the inside of the fresh water tank 3 through the water pipe 321 and then pumps it into the valve body 1 through the water supply pipe 33 to continuously supply water to the water terminal inside the vehicle. The start and stop of the water pump 32 are controlled by the circuit switch 4 to realize automatic start and stop of the mode without manual operation.

[0026] In this invention, the circuit switch 4 includes a sealing cylinder 41, which is fixedly embedded in the through hole at the top of the valve body 1. A sealing piston 43 is vertically slidably mounted inside the sealing cylinder 41. An insulating rod 42 is fixedly mounted on the outside of the sealing piston 43. The insulating rod 42 extends outward through the sealing cylinder 41 and is fixedly mounted with an arc-shaped ball 421. The insulating rod 42 is slidably connected to the inner wall of the sealing cylinder 41. A conductive bridge 45 is fixedly mounted on the top of the sealing piston 43. Two sets of symmetrically arranged conductive blocks 46 are fixedly mounted on the top of the inside of the sealing cylinder 41. The two sets of conductive blocks 46 are electrically matched with the conductive bridge 45 to realize the circuit connection and disconnection.

[0027] Among them, the circuit switch 4 is the core of the system mode switching. Relying on the squeezing cooperation between the arc ball 421 and the cam 68, it drives the sealing piston 43 to slide vertically, controlling the contact and separation of the conductive bridge 45 and the conductive block 46, and accurately realizing the switching of the power supply circuit of the water pump 32 and the external water source indication circuit. The overall structure has good sealing performance, is waterproof and dustproof, and is suitable for the complex use environment of RVs that are humid and bumpy.

[0028] In this invention, a tension spring 44 is fixedly installed between the bottom of the sealing piston 43 and the inner bottom wall of the sealing cylinder 41. The tension spring 44 is sleeved on the outside of the insulating rod 42, and an indicator light 47 is fixedly installed on the top outer side of the sealing cylinder 41.

[0029] Among them, the tension spring 44 provides automatic reset tension for the sealed piston 43, ensuring that the circuit switch 4 automatically resets and cuts off power when there is no external squeezing force, thus avoiding accidental circuit triggering; the indicator light 47 is used to intuitively display the current water supply mode, and lights up in the external water source mode, making it easy for users to intuitively judge the working status of the equipment.

[0030] In this invention, six connecting rods 651 are fixedly installed in a ring on the outer side of the second hexagonal rod 65. Sealing posts 69 are fixedly installed at the outer ends of the six connecting rods 651. Six external water connection holes 611 are opened in a ring on the isolation plate 61. The sealing posts 69 and the corresponding external water connection holes 611 are sealed and inserted into each other.

[0031] Among them, the six sets of connecting rods 651 and sealing column 69 are synchronously linked, which can follow the axial displacement of the second hexagonal rod 65 to realize synchronous opening and closing, accurately control the opening and closing of the external water connection hole 611, and then switch the internal water circuit connection path of the valve body 1, realize the physical isolation and switching of the dual water source circuit, have good sealing effect, strong switching stability, and can greatly reduce the problem of cross-flow and seepage caused by switching lag.

[0032] In this invention, a first spring cavity 621 is provided at one end of the first hexagonal rod 62 near the second hexagonal rod 65, the second hexagonal rod 65 is slidably connected to the inner wall of the first spring cavity 621, and a first spring 622 is fixedly installed between the first spring cavity 621 and the end of the second hexagonal rod 65.

[0033] The first spring 622 provides the normal reset force for the second hexagonal rod 65. After the water pressure of the external water source disappears, it can automatically pull the second hexagonal rod 65 to reset, so that the equipment can automatically switch back to the self-supply mode, ensuring the automation of mode switching and the accuracy of reset.

[0034] In this invention, a connecting seat 66 is fixedly mounted on the end of the second hexagonal rod 65 away from the isolation plate 61. A third spring cavity 661 is opened inside the connecting seat 66. The end of the second hexagonal rod 65 is slidably connected to the inner wall of the third spring cavity 661. A third spring 662 is fixedly installed between the second hexagonal rod 65 and the inner wall of the third spring cavity 661. A clean water sealing plug 67 is fixedly installed on the side of the connecting seat 66 near the clean water tank interface 14. The clean water sealing plug 67 is sealed and adapted to the clean water tank interface 14. Under normal conditions, the clean water sealing plug 67 does not contact the clean water tank interface 14 and maintains the water circuit conduction state.

[0035] Among them, the third spring 662 provides elastic buffer and sealing pre-tightening force. When switching to the external water source mode, it can ensure that the clean water sealing plug 67 fits tightly to block the clean water tank interface 14, completely isolate the self-supply water circuit, effectively suppress the problem of backflow and cross-flow of external water source, and ensure that the two water circuits operate independently and do not interfere with each other.

[0036] In this invention, a connecting rod 63 is fixedly mounted on the end of the first hexagonal rod 62 away from the isolation plate 61. A second spring cavity 631 is formed inside the connecting rod 63. The end of the first hexagonal rod 62 is slidably connected to the inner wall of the second spring cavity 631. A second spring 632 is fixedly installed between the first hexagonal rod 62 and the inner wall of the second spring cavity 631. A venting sealing plug 64 is fixedly mounted on the end of the connecting rod 63 away from the first hexagonal rod 62. The venting sealing plug 64 is sealed and inserted into the venting hole 13.

[0037] The second spring 632 provides normal sealing elasticity to the drain sealing plug 64, so that the drain hole 13 is normally sealed and closed to prevent water leakage; at the same time, it can be used in conjunction with manual pressing to temporarily open the drain hole 13, complete the drainage of water in the pipeline, and prevent the problem of residual water quality breeding bacteria and low temperature freezing cracking of pipeline.

[0038] In this invention, a pressing handle 7 is fixedly installed on the outer end of the venting sealing plug 64, and the outer end of the pressing handle 7 passes through the venting hole 13 and is fixedly equipped with a gripping head 71.

[0039] The handle 7 can be manually pressed by holding head 71, which drives the vent sealing plug 64 to compress the second spring 632 and move it inward, opening the vent hole 13, so as to manually vent the residual water inside the valve body 1. The structure is simple and easy to operate, which improves the safety and durability of the equipment.

[0040] In this invention, the fixed bracket 2 includes a bracket mounting plate 21, on which a plurality of mounting holes 211 are evenly provided, and two fixing plates 22 are symmetrically fixedly installed on the inner side of the bracket mounting plate 21, and each of the two fixing plates 22 is provided with a slot 221.

[0041] Among them, the fixed bracket 2 provides overall fixed support for the valve body 1. The equipment can be fixed inside the water cabinet of the RV through the mounting hole 211. The slot 221 can be used with the buckle to complete the limit locking. The installation is firm, suitable for the small assembly space of the RV, and has strong shock resistance, avoiding the equipment from loosening and shifting due to vehicle bumps.

[0042] Working principle: 1. No external water source, vehicle-mounted self-water supply mode (RV travel, independent parking) The external water source interface 12 is not connected to an external water pipe, there is no water pressure on the left side of the valve body 1, and there is no axial pressure difference on the left side of the isolation plate 61. The first spring 622 pulls the second hexagonal rod 65 to keep it in the left position, and the six sets of sealing columns 69 are fully inserted into the external water connection hole 611, completely sealing the external water circuit; the clean water sealing plug 67 is separated from the clean water tank interface 14, and the clean water tank interface 14 is connected to the water terminal interface 11 through the internal cavity of the valve body.

[0043] When cam 68 is in the left position, it squeezes the arc ball 421 of the left circuit switch 4, pushes the sealing piston 43 to slide upward, and the conductive bridge 45 is in contact with the conductive block 46, so that the power supply circuit of water pump 32 is turned on and in standby mode; when cam 68 separates from the arc ball 421 of the right circuit switch 4, the external water source indicator light 47 is turned off and goes out.

[0044] Pressure sensor 5 monitors the water pressure in the valve body's water circuit in real time. When the user opens the in-vehicle water terminal valve, the water pressure in the pipeline drops, and pressure sensor 5 sends a low-pressure signal to the RV control terminal. The control terminal then starts water pump 32. Water pump 32 draws clean water from the clean water tank 3 through the pump pipe 321, sends it to the valve body 1 through the water supply pipe 33, and finally delivers it to the in-vehicle water equipment through the water terminal interface 11, achieving automatic water supply. When the water terminal is closed, the water pressure in the pipeline rises again, pressure sensor 5 sends back a high-pressure signal, and water pump 32 automatically stops.

[0045] 2. Connect to an external water source; campsite external water supply mode. The user connects the external water supply pipe to the external water source interface 12 and turns on the external water source. The water flows into the left chamber of the valve body 1. The annular pressure-bearing sealing surface of the isolation plate 61 forms a sealed water pressure chamber. The water pressure generates an axial pressure difference to the right, which pushes the second hexagonal rod 65 to slide to the right against the elastic force of the first spring 622.

[0046] Six sets of sealing columns 69 move to the right simultaneously and disengage from the external water connection hole 611, and the external water source interface 12 is directly connected to the water terminal interface 11; the second hexagonal rod 65 drives the connecting seat 66 and the clean water sealing plug 67 to move to the right simultaneously, the clean water sealing plug 67 presses the clean water tank interface 14, and the third spring 662 provides pre-tight sealing force to completely isolate the water circuit of the vehicle-mounted clean water tank and prevent water leakage and backflow.

[0047] Synchronous Action: After cam 68 moves to the right, it disengages from the arc-shaped ball 421 of the left-side circuit switch 4. The left-side tension spring 44 pulls the sealing piston 43 downward, separating the conductive bridge 45 from the conductive block 46, thus de-energizing and stopping the water pump 32. Cam 68 then presses against the arc-shaped ball 421 of the right-side circuit switch 4, causing the right-side conductive bridge 45 to engage with the conductive block 46. The indicator light 47 on the external water source side illuminates, providing a clear indication of the current water supply mode. The cam employs a staggered stroke structure, preventing simultaneous pressing of two sets of arc-shaped balls during the middle stage of displacement, thus avoiding conflicting conditions where the water pump and indicator light are simultaneously energized.

[0048] 3. Disconnect external water supply, automatically reset, and drain pipeline. After the external water source is disconnected, the water pressure on the left side of the valve body disappears, the first spring 622 pulls the second hexagonal rod 65 to the left to automatically reset: the sealing column 69 re-seals the external water connection hole 611, the clean water sealing plug 67 disengages from the clean water tank interface 14, the cam 68 resets and squeezes the left circuit switch 4, the water pump circuit returns to standby, and the system automatically switches back to the vehicle self-water supply mode.

[0049] If water remains inside the valve body and pipeline, the user can press the grip head 71 inward. Pressing the handle 7 will cause the drain sealing plug 64 to compress the second spring 632 and retract inward, opening the drain hole 13 and allowing the water in the pipeline to drain out from the drain hole 13. After the water is drained, release the grip head 71, and the second spring 632 will push the drain sealing plug 64 to reset, resealing the drain hole 13 to prevent water leakage.
