DETAILED DESCRIPTION

[0019] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0021] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0022] To solve the technical defects mentioned in the background art, the present embodiment provides a structure for instant sanitation service on the way and a driving tool.

[0023] The present application will be described in further detail below with reference to the accompanying drawings: As shown in the drawings, Figures 1-2 The first aspect of the embodiments of the present application provides a structure for instant sanitation service on the way, comprising: a containing main body 6 having a containing cavity for containing excrement; a cover plate 1 rotatably connected to the top of the containing main body 6 for opening or blocking the containing cavity; a conveying pipeline having one end connected to the containing cavity and the other end connected to an excrement collector 11; a pipeline switch arranged in the conveying pipeline and close to the containing cavity; a pneumatic sewage discharge gas storage element 7 having one end located in the containing main body 6 and the other end signal connected to the pipeline switch; an atomized fragrance generating device 5 fixedly arranged on the containing main body 6 and in communication with the containing cavity; a detection unit fixedly arranged on the containing main body 6 for detecting whether the cover plate 1 is closed; wherein when the containing cavity contains excrement and the cover plate 1 forms a sealed blockage to the containing cavity, the pneumatic sewage discharge gas storage element 7 acts on the containing cavity and forms a transient negative pressure environment inside the containing cavity, the pipeline switch is opened in response to the negative pressure environment, and the excrement is conveyed to the excrement collector 11 through the conveying pipeline.

[0024] The above structure guarantees the airtightness of the excrement temporary storage stage under the dynamic working condition of the vehicle body 12, and replaces passive discharge with transient negative pressure driving, significantly improving the sewage discharge efficiency and reliability; taking the closure of the cover plate 1 as the starting premise, the risk of non-sealed sewage discharge is eliminated; with the intervention of the atomized fragrance generating device 5 after the completion of sewage discharge, the targeting and timeliness of odor control are realized, the overall structure is highly integrated, and it is suitable for the limited space constraint of vehicles.

[0025] In the implementation, the containing body 6 is a rigid shell structure, which can be made of stainless steel, reinforced polypropylene (PP), or carbon fiber composite material, and has a wall thickness of 2 mm to 4 mm to balance strength and light weight; the containing cavity is a funnel-shaped chamber that is wide at the top and narrow at the bottom, and is provided with an interface flange that matches the conveying pipeline at the bottom; the inner surface of the cavity is coated with a hydrophobic and oleophobic anti-adhesion coating (such as a fluorosilane modified coating) to reduce the adhesion rate of the filth; the containing body 6 is embedded in the cavity below the rear seat of the vehicle, and its outer contour is fixed to the longitudinal beams and cross beams of the vehicle floor 12, without protruding from the bottom surface of the passenger compartment, ensuring that the appearance is consistent with that of a conventional seat base in the unused state.

[0026] The cover plate 1 is a rigid flat plate or an arc-shaped plate made of the same material as the containing body 6 or an engineering plastic (such as POM), and its rotating connection methods include but are not limited to hinge connection, shaft-bearing pair, or torsional spring support structure; the cover plate 1 is slightly larger than the projection area of the opening of the containing cavity, and is provided with an elastic sealing strip (such as silicone or EPDM rubber) at the edge; when the cover plate 1 is rotated to the sealing position, the sealing strip is deformed under pressure and forms a linear contact seal with the top end surface of the containing body 6; this structure can be replaced by a magnetic quick-release cover plate 1, that is, a permanent magnet is embedded on the back of the cover plate 1, and a magnetically conductive metal ring is provided at the corresponding position on the top of the containing body 6, so as to realize automatic positioning and auxiliary sealing by magnetic attraction.

[0027] The conveying pipeline is a flexible or semi-rigid sewage pipe 10 made of corrosion-resistant and high-toughness material, such as TPU, EPDM rubber-lined stainless steel corrugated pipe, or silicone composite pipe, with an inner diameter of 25 mm to 40 mm and a wall thickness of 1.5 mm to 3 mm; one end of the pipeline is connected to the bottom of the containing cavity through a clamp or a quick connector, and the other end extends to the outside of the vehicle body 12 and is connected to the filth collector 11; the pipeline can be replaced by a segmented structure, with a rigid stainless steel short pipe used in the segment near the containing cavity to withstand negative pressure deformation, and a flexible pipe used in the distal segment to adapt to the vibration of the vehicle body 12 and assembly tolerances.

[0028] In this embodiment, the pipeline switch is a one-way check valve 9.

[0029] The pneumatic sewage storage device 7 is a sealed pressure vessel, one end of which extends into the containing cavity through a through hole for direct action on the gas phase space in the cavity; the other end is connected to the pipeline switch through a signal connection line 8; the storage device can be replaced by a vacuum generator, which uses the compressed air source (0.6-0.8 MPa) of the vehicle to generate negative pressure through a Venturi tube, with the output end connected to the containing cavity and the input end controlled by a solenoid valve; at this time, the signal connection is a synchronous logical association between the solenoid valve on-off command and the pipeline switch opening-closing command.

[0030] The atomizing fragrance generating device 5 is a piezoelectric micro-porous atomizer or an ultrasonic atomizing module, which is fixed in the side wall or the inner side of the top cover of the containing body 6, and the atomizing output end thereof is communicated with the containing cavity through a gas guide pipe or a direct connection opening. The inner cavity of the device can be loaded with fragrance liquid containing plant essential oil or activated carbon loaded odor-removing liquid, and the atomized particle size is 5-20 pm. The starting time of the device is strictly controlled by the sewage discharge completion signal, that is, it is started only after the pipeline switch is closed and the pressure in the conveying pipeline is restored to normal pressure with a delay of 1-3 seconds. The structure can be replaced by a slow-release fragrance module, that is, a porous ceramic carrier is embedded in the inner wall of the containing cavity, and the microencapsulated fragrance components are loaded. When the cover plate 1 is opened, the components are released due to air flow disturbance, but the active atomization mode is adopted in the embodiment to ensure that the odor is covered immediately after sewage discharge.

[0031] The detection unit is a non-contact position sensor, which is fixed in the top side wall or the inner side of the end cover 3 of the containing body 6, and the detection end thereof faces the movement track plane of the cover plate 1. The detection principle is based on infrared reflection, laser ranging or ultrasonic echo time difference, and the output high-low level or digital signal represents whether the cover plate 1 is in the fully closed position. The installation height is 8-15 mm from the closest point when the cover plate 1 is closed, which ensures stable identification. The structure can be replaced by a combination of a Hall sensor and a magnetic steel, that is, a permanent magnet is embedded in the closed position of the cover plate 1, and a Hall element is arranged at the corresponding position of the containing body 6 to determine the closed state by the jump of the magnetic field strength.

[0032] When the user completes the toilet operation and closes the cover plate 1 during the vehicle travel, the detection unit identifies the closed state of the cover plate 1 in real time and sends a confirmation signal to the vehicle body control system. The vehicle machine system discharges air according to the instruction of the pneumatic sewage storage gas element 7, and forms a transient negative pressure environment in the containing cavity. The negative pressure directly acts on the surface of the excrement, and also promotes the opening of the pipeline switch through signal connection. Therefore, the excrement in the containing cavity is driven by the negative pressure difference and is efficiently sucked through the conveying pipeline to the excrement collector 11 located outside the vehicle body 12. After the sewage discharge is completed, the pipeline switch is closed, and the pressure in the cavity is balanced, the atomizing fragrance generating device 5 is started to atomize the odor-removing fragrance into micron-sized particles and uniformly disperse them in the containing cavity to eliminate the residual odor.

[0033] Since the containing body 6 and the cover plate 1 form a reliable sealed cavity, the technical problems of excrement leakage and odor diffusion during travel are solved. Since the pneumatic sewage storage gas element 7 and the pipeline switch are directly physically responsive or deterministically signal-related through the negative pressure environment, the technical problems of loose control logic and unreliable sewage discharge are solved. Since the atomizing fragrance generating device 5 is strictly started after the sewage discharge action, the technical problems of odor treatment lag and uneven coverage are solved. Finally, the technical effect of safely, cleanly, silently and automatically completing the whole process of sanitary service in a dynamic vehicle environment is achieved.

[0034] In this embodiment, the accommodating body 6 is connected with the mounting ring 4, the top of the mounting ring 4 is connected with the end cover 3, the top of the end cover 3 is provided with the heating pad 2; the outer side of the end cover 3 is symmetrically provided with the mounting plate, and the two mounting plates are connected with the rotating shaft; the outer side of the cover plate 1 is provided with the connecting plate, and the connecting plate is rotationally connected with the rotating shaft; wherein, when the cover plate 1 rotates counterclockwise, the cover plate 1 is separated from the heating pad 2 to open the accommodating cavity; when the cover plate 1 rotates counterclockwise, the bottom of the cover plate 1 is attached to the surface of the heating pad 2 to block the accommodating cavity.

[0035] From Figure 1 It can be seen from the above technical scheme that when the user opens the cover plate 1 in a low temperature environment, the heating pad 2 is already in a preheating state, and the warm seat surface is exposed after the cover plate 1 is turned up; during the closing process of the cover plate 1, the bottom thereof naturally presses the surface of the heating pad 2, on the one hand, the sealing property of the accommodating cavity is improved by means of the contact pressure, and the risk of gas leakage during the negative pressure pollution discharge stage is reduced; on the other hand, the body of the cover plate 1 is used as a heat dissipation surface to delay the sudden drop of the surface temperature of the heating pad 2 and maintain the comfortable touch feeling interval; in addition, the whole structure is compactly arranged on the top of the accommodating body 6, without increasing the overall height of the equipment, and is suitable for the available installation space ≤120mm below the rear seat of the vehicle.

[0036] Further, if the accommodating body 6 is a ring structure, in order to enable the user to successfully complete the operation in the vehicle, a through hole is formed on the end cover 3 and the heating pad 2, and the two through holes are axially coincident and communicate with the accommodating cavity.

[0037] Further, the mounting hole is formed on the accommodating body 6, one end of the mounting hole penetrates the outer wall of the accommodating body 6 and communicates with the outside, and the other end communicates with the accommodating cavity; the atomizing fragrance generating device 5 is detachably assembled in the mounting hole, and the atomizing output end is arranged towards the accommodating cavity; the atomizing fragrance generating device 5 is used to atomize the fragrance liquid to form micron-level particles, and the atomizing fragrance generating device 5 is started after the excrement is transported to the excrement collector 11 through the conveying pipeline, so as to uniformly disperse the atomized particles in the interior of the accommodating cavity.

[0038] The atomized fragrance generating device 5 is a micro atomization module independently packaged, including an atomization sheet, a liquid storage cavity, a micro pump, a PCB control board and a sealed connection interface. The atomization sheet is a piezoelectric ceramic micro-porous atomization sheet, with a micro-pore diameter of 3-8 μm and a working frequency of 100-120 kHz, which can stably generate fragrance aerosol with a particle size Dv50=2.5-5.0 μm. The liquid storage cavity has a volume of 8-12 mL, and a screwable sealing cover is provided at the top of the cavity. The cover body is integrated with a silica gel sealing ring and a liquid level observation window. The PCB control board is provided with a delay trigger circuit, which receives cooperative signals from a detection unit and a pipeline switch. Only when the detection unit confirms that the cover plate 1 is closed and the pipeline switch completes a one-time opening-closing cycle (i.e. the end of the decontamination conveying action), the atomization is started after a delay of 1.5-3.0 seconds, and the continuous working time is 6-10 seconds. The device is detachably assembled in the mounting hole through a double fastening mode of buckling and threading. When disassembled, no tools are needed, and the whole machine can be pulled out by pressing the buckle with one hand, supporting quick replacement of consumables or the whole machine.

[0039] After the instant sanitation service structure completes the decontamination conveying operation, the atomized fragrance generating device 5 obtains an external power supply and signal access channel, and ensures that the atomized output directly reaches the target space, because the mounting hole penetrates the inside and outside and is accurately positioned. The detachable assembly structure is simple and reliable, supports tool-free quick disassembly, and significantly reduces the operation and maintenance threshold. The micron-level atomization capability and directional output design work together to make the fragrance particles have a high specific surface area and a low settling rate, which can maintain an effective suspension distribution in the containing cavity for 30-60 seconds. The starting time is strictly limited after the decontamination action is completed, avoiding the interference of the negative pressure environment on the atomized airflow, and ensuring that all atomized products remain in the cavity to play a deodorizing effect.

[0040] In this embodiment, the pneumatic decontamination gas storage member 7 is connected with an air outlet valve and an exhaust pipeline, and the exhaust pipeline is arranged outside the containing main body 6. When the containing cavity contains decontamination objects and the cover plate 1 seals the containing cavity, the air outlet valve is opened, so that the compressed gas in the pneumatic decontamination gas storage member 7 is discharged to the outside through the exhaust pipeline, thereby forming a transient negative pressure environment inside the containing cavity.

[0041] The pneumatic decontamination gas storage member 7 is a core energy storage and release unit for providing a transient negative pressure driving force to the containing cavity. It is a sealed pressure container for storing pre-charged compressed gas. The gas storage member is in communication with the inside of the containing main body 6 through a rigid or flexible pipeline, one end of which extends into the containing cavity to realize pressure coupling, and the other end establishes a controllable response relationship with the air outlet valve through a signal line or a mechanical linkage structure.

[0042] As an optional embodiment, the gas storage member can also be integrated with a pressure sensor and a temperature compensation module to real-time feedback the internal state and participate in closed-loop control.

[0043] The air outlet valve is a fluid on-off actuator controlled by opening and closing, which is arranged at the air outlet of the pneumatic decontamination gas storage member 7, and the valve core adopts electromagnetic drive, piezoelectric drive or pneumatic pilot structure; after the vehicle system receives the signal that the cover plate 1 has been closed and confirms that there is excrement in the containing cavity, the air outlet valve opening operation is started after 3-5 seconds delay.

[0044] As an optional embodiment, the air outlet valve can also be replaced by an electric proportional valve with flow regulation function to realize controllable regulation of negative pressure gradient.

[0045] The exhaust pipe is a special channel for directing compressed gas out of the vehicle, one end of which is sealed and connected with the outlet of the air outlet valve, and the other end penetrates the outer wall of the containing main body 6 and extends to the airflow disturbance area outside the vehicle body 12; the whole pipe is in L or S shape to avoid the direction of straight through the passenger compartment, and the outer wall of the pipe is provided with a clamp mounting seat, which is fixed with the vehicle body 12 longitudinal beam or chassis cross beam through a damping rubber pad to suppress the transmission of driving vibration.

[0046] As an optional embodiment, a muffler or a flow guide fin can be installed at the end of the exhaust pipe to reduce exhaust noise and optimize the tail airflow separation characteristics.

[0047] Further, the exhaust pipe is arranged outside the containing main body 6, which means that all pipe sections do not penetrate the surrounding wall structure of the containing main body 6, nor enter the containing cavity, the conveying pipeline or the space where the fragrance generating device 5 is located; its layout path avoids the passenger leg movement area, high-voltage wire harness and brake pipeline, and is laid along the inside of the vehicle body 12 bottom longitudinal beam or the cavity inside the rear bumper; this arrangement ensures that the compressed gas discharge path is physically isolated from the vehicle air system, eliminating the risk of backflow of exhaust gas.

[0048] As an optional embodiment, the exhaust pipe can also be integrated into the rear bumper styling surface, with its outlet hidden in the grid gap or the edge of the diffuser, realizing the integration of function and appearance.

[0049] In this scheme, the pneumatic decontamination gas storage member 7 is a compressed air tank, which is used as a specific implementation form of the pneumatic decontamination gas storage member 7, and the high-pressure gas pre-stored in it drives the containing cavity to form a negative pressure environment instantaneously in a controllable release process, thereby realizing the active, closed and directional transportation of excrement; this structure selection considers the vehicle space constraint, response speed, cyclic use and engineering maturity, and improves the operation reliability and adaptability of the sanitary service structure in complex conditions such as vibration, temperature change and power limitation during travel.

[0050] The pneumatic pollution discharge gas storage member 7 is a compressed air tank, which is a closed pressure container with a rigid shell, can withstand a working pressure of 0.6-0.8 MPa, is internally filled with dry and clean compressed air, does not rely on real-time air supply of a vehicle power system, and belongs to a passive air source device. The tank body can be made of aluminum alloy or carbon fiber winding composite material, and has the characteristics of light weight, corrosion resistance and impact resistance.

[0051] In an alternative embodiment, the compressed air tank can also be replaced by a metal gas cylinder pre-filled with nitrogen, or an integrated air source unit composed of a miniature piston type mechanical supercharging module and a buffer gas storage cavity, as long as it can release ≥1.5 L of standard state gas in ≤0.5 seconds and the pressure in the cavity after exhaust is reduced to below -30 kPa, the same negative pressure driving effect can be achieved.

[0052] When the containing cavity contains the filth and the cover plate 1 is sealed, the compressed air tank serves as a stable, fast and offline air source, which releases high-pressure gas to the outside through the exhaust pipe under the action of the exhaust valve, so that a negative pressure environment is formed in the containing cavity. The negative pressure environment directly acts on the pipeline switch, which is opened in response, thereby driving the filth to be unidirectionally conveyed along the conveying pipeline to the filth collector 11, so that the instant sanitation service structure can reliably complete the closed pollution discharge operation in the vehicle driving state, and the passenger privacy, the cabin air cleanliness and the stability of the vehicle electrical system are ensured.

[0053] In the embodiment, the detection unit is arranged on the containing body 6, and the detection end faces the cover plate 1. By physically positioning the detection unit on the body structure of the containing body 6 and making the detection end axially face the plane where the movement track of the cover plate 1 is located, the stable, direct and unobstructed perception of the closed state of the cover plate 1 is realized. This arrangement avoids signal attenuation, false triggering or missed detection caused by installation position deviation, angle inclination or relative displacement, and is especially suitable for multi-dimensional vibration, acceleration change and space limited working conditions that exist during vehicle travel.

[0054] The detection unit does not rely on power supply or mechanical linkage of the cover plate 1, and only needs to be rigidly connected to the containing body 6 and face the cover plate 1 to complete state feedback. The structure is simple, reliable and strong in anti-interference, and provides a basic criterion for accurate start and stop of the subsequent negative pressure pollution discharge process.

[0055] The detection unit is arranged on the accommodating body 6, that is, the detection unit is integrated on the outer wall, side wall or top support structure of the accommodating body 6 in a fixed assembly manner, the installation base surface of the detection unit maintains a static relative relationship with the accommodating body 6, and the detection unit can be fixedly connected to the accommodating body 6 by means of a threaded fastener, a buckle or adhesive glue, so that the detection unit is not loosened, displaced or deflected in the process of vehicle running. The installation manner enables the detection unit to form a stable reference relationship with the accommodating cavity, and avoids introducing measurement errors due to tolerance of the rotating pivot of the cover plate 1 or deformation of the connecting plate.

[0056] As an optional embodiment, the detection unit can also be embedded in the groove reserved on the top edge of the accommodating body 6, and the shell of the detection unit is flush with the outer surface of the accommodating body 6, so that the influence of wind resistance is reduced and the protection level is improved. Alternatively, a reinforcing rib can be additionally arranged on the side of the accommodating body 6 corresponding to the rotating path of the cover plate 1, and the detection unit is arranged on the surface of the reinforcing rib, so that the installation rigidity and thermal stability are further improved.

[0057] In the dynamic running environment of the vehicle, because the detection unit is rigidly fixed on the accommodating body 6 and the detection end strictly faces the closed surface of the cover plate 1, the detection unit can stably output a real state signal reflecting the physical position of the cover plate 1. The signal is not disturbed by the opening and closing of the pipeline switch, the pressure fluctuation of the pneumatic blowdown gas storage element 7 or the start and stop of the atomized fragrance generating device 5. Further, the control system can accurately delay the trigger of the negative pressure blowdown process after confirming that the sealing is established, so as to avoid leakage of excrement, diffusion of odor or insufficient negative pressure caused by early opening of the pipeline switch, and to avoid failure of delivery. Finally, the accuracy of the automatic response of the instant sanitation service structure during the journey, the running safety and the consistency of the user experience are improved.

[0058] In the implementation, the detection unit is one of an infrared sensor, a laser ranging sensor or an ultrasonic ranging sensor. After the cover plate 1 completes the mechanical closing action, any one of the infrared sensor, the laser ranging sensor or the ultrasonic ranging sensor independently completes the high-reliability identification of the closed-in-place state. Because the detection unit adopts a non-contact sensing mechanism, the false judgment caused by mechanical contact wear and dirt adhesion is avoided. Because the three types of sensors all have millisecond-level response capability and sub-millimeter-level positioning resolution, it is ensured that the final stationary position of the cover plate 1 can still be accurately captured in the vibration working condition of the vehicle running.

[0059] In the scenes of long-distance driving, emergency rescue and special operation, vehicle occupants often face the realistic dilemma of inconvenient or even no place to go to the toilet: existing vehicles are not equipped with sanitation facilities, and temporary parking has safety hazards and time costs; portable containers are prone to leakage, odor diffusion and cleaning difficulties, and cannot adapt to the dynamic environment during the journey; the vehicle-mounted simple toilet relies on gravity blowdown, and is limited by the installation attitude and the inclination of the vehicle body, so that the blowdown is not complete and the residual excrement breeds bacteria; at the same time, the traditional scheme lacks airtightness, odor removal cooperation and automatic control, resulting in air pollution in the vehicle, poor user experience and high maintenance frequency.

[0060] The above problems are mainly manifested as: it is difficult to provide safe, sanitary, instant, low-invasive, and integrated toilet service in a traveling state, which restricts the functional integrity and humanization level of vehicles in long-time, closed, and mobile scenarios.

[0061] To this end, a second aspect of the embodiments of the present application provides a driving tool, which includes a vehicle, and the vehicle is installed with the instant sanitary service structure in a traveling process.

[0062] Without changing the main structure of the vehicle body and without occupying the effective space of the passenger cabin, all pollution-related components (including the pneumatic pollution storage gas component 7, the conveying pipeline, and the excrement collector 11) are arranged outside the vehicle body 12 or in the hidden area below the seat, which not only guarantees the cleanliness and safety of the vehicle interior but also realizes wind resistance optimization and modeling integration; the system is powered by the vehicle power supply network and is connected to the vehicle CAN bus (Controller Area Network), supports state interaction and instruction response with the vehicle electronic control unit (ECU), and thus completes the full-process closed-loop control such as cover plate 1 opening and closing detection, negative pressure triggering, excrement conveying, and fragrance releasing in the vehicle running state.

[0063] Upgrading the single-point sanitary device to a vehicle-level human factor system significantly improves the vehicle survival support capability in special working conditions, expands the vehicle application scenario boundary, and reserves communication and execution interfaces for subsequent intelligent operation and maintenance (such as excrement overflow warning, consumable replacement prompt, and health data collection).

[0064] Among them, the driving tool generally refers to a mobile device with autonomous driving capability and carrying personnel, including but not limited to passenger cars, commercial vehicles, special vehicles (such as ambulances, police vehicles, recreational vehicles), special operation vehicles, and automatic driving shuttle vehicles; the chassis configuration can be fuel-driven, hybrid or pure electric-driven, and there is no specific limitation on the power form.

[0065] The vehicle as a specific physical carrier of the driving tool specifically refers to a four-wheel and above road vehicle with a closed passenger cabin in the embodiment, and the vehicle body 12 structure includes a frame, a vehicle body cover, a seat system, and a wire harness layout system; the vehicle is internally configured with a standard 12V / 24V low-voltage power supply system and a CAN communication bus to provide power supply and signal interaction channels for the sanitary service structure.

[0066] The on-the-go instant sanitation structure is installed in the above-mentioned position, that is, the sanitation structure is embedded in the existing structure of the vehicle in the form of a complete function, independently operating minimum technical unit, through mechanical fixation and electrical connection; the installation position can be selected as the cavity area below the rear seat, using the seat slide rail, floor crossbeam or subframe as the force bearing base, and rigid connection is achieved by bolt fastening, buckle locking or adhesive bonding; the whole structure shares the ground terminal with the vehicle body, and the electrical interface is connected to the vehicle wire harness branch through a waterproof aviation plug, ensuring long-term reliability under the conditions of vibration, temperature change and electromagnetic compatibility; this installation method does not damage the original vehicle sealing structure, does not interfere with the safety airbag layout path and the collision energy absorption area, and meets the relevant requirements of the national standard.

[0067] The on-the-go instant sanitation structure in this embodiment specifically represents a sealed negative pressure sewage discharge system that meets the adaptability of dynamic working conditions, and its constituent elements strictly correspond to the above-mentioned defined set of technical features, including the containing body 6 and its containing cavity, the cover plate 1 and its rotating connection relationship, the communication path of the conveying pipeline and the excrement collector 11, the position constraint of the pipeline switch, the double-end positioning and signal connection relationship of the pneumatic sewage discharge gas storage element 7, the fixed installation way and communication logic of the atomized fragrance generating device 5, and the installation position and detection directivity of the detection unit; each component maintains the original function definition and relative spatial relationship unchanged in the integrated state of the vehicle, and only adjusts the local installation posture according to the envelope of the vehicle body 12 and the human-machine engineering demand; the parameter range, connection relationship and control logic of all technical features are inherited from the above, without expansion or narrowing.

[0068] When the vehicle is in a running state, the occupant opens the rear seat cover plate 1, the system confirms the opening operation of the cover plate 1 through the detection unit, enters the standby mode, closes the cover plate 1 after defecation, the detection unit identifies the sealing state and sends a signal to the vehicle ECU, the ECU sends an instruction to the pneumatic sewage discharge gas storage element 7 through the CAN bus, the outlet valve is opened, the compressed gas is discharged to the outside through the exhaust pipe, and the negative pressure is formed in the containing cavity and the conveying pipeline; the pipeline switch is automatically opened under the action of negative pressure, and the excrement is sucked into the excrement collector 11 located below the tail of the vehicle under the driving of pressure difference; after the conveying is completed, the pipeline switch is closed, the system delays for 3-5 seconds to start the atomized fragrance generating device 5, atomizes the fragrance liquid into micron-sized particles, and uniformly disperses in the inner wall of the containing cavity and the airflow path, eliminating the residual odor; the whole process does not require the occupant to manually operate the valve or clean the components, and all high-pollution links are physically isolated from the passenger compartment.

[0069] Therefore, the technical problems of difficult defecation, unreliable excretion, difficult odor control and difficult space coordination of passengers in the traveling state are solved, and the technical effects of improving the applicability of the vehicle in all working conditions, ensuring the physiological dignity and health safety of passengers, and reducing the operation and maintenance complexity are achieved.

[0070] Further, the vehicle includes a vehicle body 12, and the front-row seat and the rear-row seat are arranged in the vehicle body 12. The instant sanitary service structure in the traveling state is arranged below the rear-row seat.

[0071] By embedding the instant sanitary service structure in the traveling state in the cavity area directly below the rear-row seat, the technical layout of concealed installation, ready-to-use and human-machine coordination is achieved, which does not occupy the leg movement space and storage space of passengers, ensures a short and direct excretion path, a reasonable pipeline layout and balanced load distribution, and takes into account the consistency of the vehicle model and the assembly maintainability.

[0072] The vehicle includes a vehicle body 12, which refers to a motor vehicle platform with a complete load-bearing structure, a power system and a driving function, including but not limited to a passenger car, a business car, a recreational vehicle or a special operation vehicle. The vehicle body 12 is a rigid main structure composed of a metal frame and a cover, and the floor longitudinal beam, the cross beam and the central channel area jointly enclose the three-dimensional installation space below the rear-row seat.

[0073] The front-row seat and the rear-row seat are arranged in the vehicle body 12, which indicates that the vehicle adopts a conventional double-row passenger arrangement, and the front-row seat is fixed behind the instrument panel and on the front floor longitudinal beam. The rear-row seat is connected to the rear floor longitudinal beam through a slide rail or a bolt. The bottom of the rear-row seat is provided with a hollow support framework, and a continuous hidden chamber is formed between the bottom plate and the floor of the vehicle body 12. The front end of the chamber is adjacent to the rear-row seat backrest adjusting mechanism, and the rear end is adjacent to the front partition plate of the trunk. The lateral direction is limited by the wheel arch lining and the rocker reinforcement, which constitutes a natural equipment integration area.

[0074] The integrated structure of the instant sanitary service on the way is arranged below the rear seat, which means that the whole accommodating body 6 is embedded in the hidden chamber between the rear seat floor and the floor of the vehicle 12, and the top opening plane is flush with or slightly lower than the lower surface of the rear seat cushion. The rotating axis of the cover plate 1 is located at the front side edge of the accommodating body 6, which is arranged in parallel with the rear seat slide rail. The conveying pipeline is led out from the bottom of the accommodating body 6, laid longitudinally below the floor of the vehicle 12, and led to the tail of the vehicle through the central passage or the inside passage of the side longitudinal beam. The pneumatic sewage discharge gas storage element 7, the pipeline switch and the atomized fragrance generating device 5 are arranged in the hidden chamber or on the structure of the vehicle 12 outside the hidden chamber, and the reference planes of all components are uniformly referred to the coordinate system (X axis is the forward direction of the vehicle, Y axis is the left-right direction, and Z axis is the vertical direction) of the vehicle 12. The integrated mode adopts a modular quick-release structure, the bottom of the accommodating body 6 is provided with four groups of positioning pins matched with the guide holes on the floor of the vehicle 12, and two groups of M8 bolts are used to realize rigid locking. The integrated position ensures that the user can complete the whole process operation of opening-use-closing without getting off the seat, and the opening angle of the cover plate 1 is controlled within 75°-90° to avoid interference with the shins of the rear passengers.

[0075] Without changing the original interior shape and seating function of the vehicle, the instant sanitary service structure on the way is deeply embedded in the space below the rear seat, which has natural advantages: high idle degree of structure, which can fully utilize the redundant space of the original vehicle; short distance from the rear passenger operation, convenient to use without additional movement; the shortest longitudinal pipeline path can reduce fluid resistance and improve sewage discharge efficiency; consistent with the gravity-assisted sewage discharge tendency, which can strengthen the effect of directional sewage transportation; and easy to build an integrated fluid circuit with the tail sewage collector 11 to optimize the overall layout of the system.

[0076] Based on the above advantages, the scheme effectively solves the core pain points of the toilet for vehicles in the background art: first, most of the existing products are portable structures, which need to be temporarily taken out and placed during use, and occupy valuable storage space in the vehicle during idle time, which seriously restricts the utilization rate of the space in the vehicle; second, the sealing performance of the external products is generally poor, which is easy to cause odor leakage and destroy the clean environment in the vehicle; third, there is no stable fixing structure, which is easy to shake or even tip over under dynamic conditions such as starting and stopping of the vehicle, which poses a significant risk to the safety of passengers such as the elderly and children in the vehicle.

[0077] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
