Detailed Implementation

[0018] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0019] It is readily understood that, based on the technical solution of this application, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

[0020] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meanings of the above in this application according to the specific circumstances.

[0022] like Figures 1-3 As shown, an embodiment of this application of an automatic hand washing and care device for vehicles includes a housing 1 disposed inside the vehicle compartment, a washing and care chamber 2 disposed inside the housing 1 and a washing and care execution mechanism 4, a sensing and detection unit 3 disposed inside the washing and care chamber 2, a sewage discharge mechanism 5 disposed below the housing 1, an interlocking mechanism 6 disposed above the housing 1 and a control module. The control module is communicatively connected to the sensing and detection unit 3 and the vehicle controller, and receives the hand detection signal detected by the sensing and detection unit 3 in the washing and care chamber 2 and the driving status signal sent by the vehicle controller. The interlocking mechanism 6 is used to lock or unlock the washing and care chamber 2 and the washing and care execution mechanism 4; The control module controls the washing and care actuator 4 according to the hand detection signal and the driving status signal. The washing and care actuator 4 includes a water supply module 41. The water supply module 41 provides cleaning water to the washing and care chamber 2 when the washing and care actuator 4 is unlocked, the hand detection signal indicates that a hand has entered the washing and care chamber 2, and the control module determines that the safety conditions are met. The sewage discharge mechanism 5 discharges wastewater to the outside of the vehicle or the vehicle drainage system when the washing and care actuator 4 is locked.

[0023] In this embodiment, an automatic hand washing and care device for vehicles includes a housing 1, a washing and care chamber 2, a washing and care actuator 4, a sensing and detection unit 3, a wastewater discharge mechanism 5, an interlocking mechanism 6, and a control module. The control module is communicatively connected to the sensing and detection unit 3 and the vehicle controller, and is used to receive hand detection signals detected by the sensing and detection unit 3 in the washing and care chamber 2 and driving status signals sent by the vehicle controller, and to control the washing and care actuator 4 based on the above signals. The washing and care actuator 4 includes a water supply module 41. When the washing and care actuator 4 is unlocked and the control module determines that the hand has entered the washing and care chamber 2 and the vehicle meets the preset safety conditions, the water supply module 41 is controlled to provide cleaning water to the washing and care chamber 2 to achieve automatic hand washing. After the water supply module 41 completes the water supply and the washing and care actuator 4 is locked, the wastewater discharge mechanism 5 is activated to discharge the wastewater generated during the washing and care process to the outside of the vehicle or the vehicle drainage system, thereby preventing sewage from stagnating in the washing and care chamber 2, improving the overall hygiene performance, and ensuring the continuous use capability of the device.

[0024] Furthermore, the interlocking mechanism 6 is located above the housing 1 and is used to lock or unlock the washing chamber 2 and the washing actuator 4. When the washing chamber 2 is not in use, it restricts the operation of the washing actuator 4, thereby effectively preventing abnormal water output or equipment malfunction caused by accidental triggering. The control module is communicatively connected to the sensing detection unit 3, the washing actuator 4, the sewage discharge mechanism 5, and the interlocking mechanism 6, respectively. Based on the sensing detection results and the interlocking status, it coordinates the control of each module, and automatically controls the water supply module 41 to start when preset conditions are met, completing the hand washing operation. This embodiment realizes the automation, safety, and integrated processing of the hand washing process in a vehicle environment, significantly improving ease of use, system reliability, and safety.

[0025] The sewage discharge mechanism 5 discharges wastewater to the outside of the vehicle or the vehicle drainage system while the washing and care actuator 4 is locked. This means that the control module triggers the sewage discharge mechanism 5 to perform drainage only after the washing and care actuator 4 has switched from the unlocked state to the locked state and the water supply module 41 has completed the water supply and cleaning operation. For the device in the initial state or in the locked state when no washing and care operation has occurred, the sewage discharge mechanism 5 does not perform drainage.

[0026] The vehicle controller is the core control unit in the vehicle's electronic control system. It can be the vehicle controller, the body control module, or a control unit related to the vehicle's operating status. It is used to collect and output the vehicle's current operating status information, including but not limited to the vehicle's driving status, speed information, parking status, gear status, and ignition status. The control module interacts with the vehicle controller through the vehicle communication bus to obtain real-time and reliable driving status signals, which are used to determine the conditions for washing and maintenance.

[0027] like Figure 1 and Figure 3 As shown, in one embodiment, the washing and care actuator 4 includes a soap supply module 42; The soap supply module 42 includes a storage tank, a first electric pump, and an outlet pipeline; The storage tank is used to store soap solution. The outlet of the storage tank is connected to the inlet of the first electric pump. The outlet of the first electric pump is connected to the inlet of the outlet pipeline. The outlet of the outlet pipeline is connected to the washing and care chamber 2. The first electric pump is turned on when the water supply module 41 provides cleaning water.

[0028] In this embodiment, the washing and care actuator 4 includes a soap supply module 42; the soap supply module 42 includes a storage tank, a first electric pump, and an outlet pipeline; the storage tank is used to store soap, the outlet of the storage tank is connected to the inlet of the first electric pump, the outlet of the first electric pump is connected to the inlet of the outlet pipeline, and the outlet of the outlet pipeline is connected to the washing and care chamber 2; the first electric pump is activated when the water supply module 41 provides washing water. Driven by the first electric pump, the soap in the storage tank can be transported to the washing and care chamber 2 along the outlet pipeline, realizing the supply of soap during the hand washing process. The structure is simple and easy to control, which is beneficial for compact arrangement in the vehicle space. Simultaneously, it can achieve on-demand soap supply according to the control signal of the control module, avoiding soap waste.

[0029] Furthermore, the soap supply module 42 is directly connected to the washing and care chamber 2, and in conjunction with the coordinated control of the sensor detection unit 3 and the control module, the soap supply is automatically started when a hand is detected entering and the preset conditions are met, so that the soap release process is coordinated with the water supply process, thereby improving the cleaning effect. At the same time, the electric pump can provide a stable output pressure, making the soap output more uniform, which is conducive to improving the cleaning coverage, enhancing the user experience, and enhancing the automation and reliability of the overall washing and care process.

[0030] like Figure 1 and Figure 3 As shown, in one embodiment, the washing and care actuator 4 includes a drying module 43, which is activated when the water supply module 41 stops supplying water for washing. The air drying module 43 includes a fan, a heating element, and an air outlet duct; The air outlet of the fan is connected to the air inlet of the air outlet duct, the heating element is installed inside the air outlet duct, and the air outlet of the air outlet duct is connected to the washing and care chamber 2.

[0031] In this embodiment, the washing and care actuator 4 includes a drying module 43, which is activated when the water supply module 41 stops providing washing water. The drying module 43 includes a fan, a heating element, and an air outlet duct. The air outlet of the fan is connected to the air inlet of the air outlet duct, the heating element is disposed inside the air outlet duct, and the air outlet of the air outlet duct is connected to the washing and care chamber 2. The fan generates airflow and delivers it to the washing and care chamber 2 through the air outlet duct. The heating element heats the airflow to form a dry airflow with a certain temperature, which dries the hands after washing, preventing moisture residue and improving the integrity and continuity of the overall washing and care process. This facilitates integrated arrangement inside the housing 1 and adapts to application scenarios with limited vehicle space.

[0032] Furthermore, by placing the heating element inside the air outlet duct, the air can be heated instantly during airflow, resulting in a more stable output airflow temperature, improved drying efficiency, and enhanced user experience. Combined with the control module, the fan and heating element can be started and stopped according to the actual usage conditions, thereby achieving on-demand drying, ensuring drying effect while reducing energy consumption. At the same time, it avoids the cross-contamination problems caused by traditional wiping methods, improving the hygiene, safety, and reliability of the device in the vehicle environment.

[0033] like Figure 1 and Figure 3 As shown, in one embodiment, the washing and care actuator 4 further includes a four-way distribution valve 44; Water supply module 41 includes a water storage tank, a second electric pump, and a water outlet pipe; the second electric pump is activated when the washing and care actuator is unlocked, the hand detection signal indicates that a hand has entered the washing and care chamber, and the control module determines that the safety conditions are met. The water storage tank is used to store cleaning water. The outlet of the water storage tank is connected to the inlet of the second electric pump, and the outlet of the second electric pump is connected to the inlet of the water outlet pipe. The four-way distribution valve 44 has a first inlet, a second inlet, a third inlet, and an outlet; The first inlet is connected to the liquid outlet end of the water outlet pipe, the second inlet is connected to the liquid outlet end of the liquid outlet pipe, the third inlet is connected to the air outlet pipe, and the outlet is connected to the washing and care chamber 2. The control module is communicatively connected to the four-way distribution valve 44 and is used to control the switching of the four-way distribution valve 44 to its on state.

[0034] In this embodiment, the washing and care actuator 4 further includes a four-way distribution valve 44; the water supply module 41 includes a water storage tank, a second electric pump, and an outlet pipe; the water storage tank is used to store washing water, the outlet of the water storage tank is connected to the inlet of the second electric pump, and the outlet of the second electric pump is connected to the inlet of the outlet pipe; the second electric pump is started when the washing and care actuator 4 is unlocked, the hand detection signal indicates that a hand has entered the washing and care chamber 2, and the control module determines that the safety conditions are met; the four-way distribution valve 44 has a first inlet, a second inlet, a third inlet, and an outlet; the first inlet is connected to the outlet of the outlet pipe, the second inlet is connected to the outlet of the outlet pipe, the third inlet is connected to the air outlet pipe, and the outlet is connected to the washing and care chamber 2; the control module is communicatively connected to the four-way distribution valve 44 and is used to control the switching of the four-way distribution valve 44 to its on / off state. The outputs of the water supply module 41, soap supply module 42, and air drying module 43 are all connected to the four-way distribution valve 44 and connected to the washing and care chamber 2 through a single outlet, realizing the centralized distribution and output of multiple media, such as clean water, soap and airflow. This effectively reduces the number of pipelines and liquid or air outlets, making the overall structure more compact and easy to integrate and arrange in the limited space of the vehicle.

[0035] This embodiment controls the switching of the four-way distribution valve 44's conduction state via a control module, enabling on-demand output of different media. This allows the water rinsing, soap supply, and drying processes to proceed sequentially according to a preset order, forming a continuous and automatic washing and care process. This avoids potential cross-interference issues caused by multi-outlet structures. Simultaneously, it improves the system's sealing and reliability, reduces leakage risks and installation and maintenance difficulties, and further enhances the device's automation level, ease of use, and stability in vehicle environments.

[0036] In one embodiment, the four-way distribution valve 44 can be a multi-way solenoid valve assembly or a rotary distribution valve.

[0037] In this embodiment, when the four-way distribution valve 44 is a multi-way solenoid valve group, the selective conduction of different passages can be achieved through the combination control of multiple solenoid valves. It has a fast response speed, high control accuracy, and is easy to link with the control module through electrical signals. When a rotary distribution valve is used, different fluid channels can be switched by rotating the valve core. The structure is relatively compact, the sealing performance is good, and it is suitable for vehicle environments with limited space and high reliability requirements.

[0038] This embodiment adopts different types of four-way distribution valves 44 structures, which can be flexibly selected according to the different requirements of the system for response speed, sealing performance and cost, thereby improving the stability and reliability of the washing and care actuator 4 in the process of switching between water, soap and air, and ensuring the smooth operation of each functional module.

[0039] like Figures 1-3As shown, in another embodiment, the housing 1 is provided with a washing cover 11 and a maintenance cover 12; The wash cover 11 is used to cover the wash chamber 2, and the maintenance cover 12 is used to cover the wash actuator 4; The interlocking mechanism 6 includes a first switch 61 and a second switch 62; The first switch 61 is used to lock or unlock the wash cover 11, and the second switch 62 is used to lock or unlock the maintenance cover 12. The first switch 61 and the second switch 62 are respectively connected to the control module for communication.

[0040] In this embodiment, the housing 1 is provided with a washing cover 11 and a maintenance cover 12; the washing cover 11 is used to cover the washing chamber 2, and the maintenance cover 12 is used to cover the washing actuator 4; the interlocking mechanism 6 includes a first switch 61 and a second switch 62; the first switch 61 is used to lock or unlock the washing cover 11, and the second switch 62 is used to lock or unlock the maintenance cover 12; the first switch 61 and the second switch 62 are respectively communicatively connected to the control module. Through the above structural arrangement, the washing chamber 2 and the washing actuator 4 are physically separated and independently covered by the washing cover 11 and the maintenance cover 12, respectively, so that the user operation area is effectively isolated from the internal actuator. This not only prevents accidental contact with internal components during use, but also facilitates the later inspection and maintenance of the actuator. Modular maintenance is achieved without affecting the use of the washing chamber 2, improving the practicality and maintainability of the device.

[0041] This embodiment sets a first switch 61 and a second switch 62 on the wash cover 11 and the maintenance cover 12 respectively, and connects them to the control module for communication. This allows the control module to obtain the opening and closing status of the wash cover 11 and the maintenance cover 12 in real time, thereby realizing interlocking control logic, avoiding accidental start-up in the maintenance or closed state, improving system safety, and enhancing the operational reliability and stability of the whole machine in the complex environment of the vehicle.

[0042] In one embodiment, the liquid storage tank is provided with a first replenishment port, and the water storage tank is provided with a second replenishment port.

[0043] In this embodiment, a first replenishment port is provided on the liquid storage tank, and a second replenishment port is provided on the water storage tank. By providing independent replenishment ports on the liquid and water storage tanks respectively, soap solution and cleaning water can be replenished separately, avoiding confusion or contamination between different media during the replenishment process, thereby ensuring the purity and safety of the media during the washing and care process. At the same time, this structure facilitates quick replenishment by users in a vehicle environment, and the refilling operation can be completed without disassembling related parts, improving the convenience of use and maintenance efficiency.

[0044] like Figures 1-3As shown, in one embodiment, the sewage discharge mechanism 5 includes a sewage pump 51 and a sewage pipe 52; One end of the sewage pump 51 is connected to the washing and care chamber 2, and the other end of the sewage pump 51 is connected to the sewage pipe 52. The other end of the sewage pipe 52 is used to discharge sewage. The sewage pump 51 is connected to the control module and is activated when the washing and care actuator is locked.

[0045] In this embodiment, the sewage discharge mechanism 5 includes a sewage pump 51 and a sewage pipe 52. One end of the sewage pump 51 is connected to the washing and care chamber 2, and the other end of the sewage pump 51 is connected to the sewage pipe 52. The other end of the sewage pipe 52 is used to discharge sewage. The sewage pump 51 is communicatively connected to the control module and is activated when the washing and care execution mechanism 4 is locked. Sewage generated in the washing and care chamber 2 can be discharged in a timely manner through the sewage pipe 52 under the drive of the sewage pump 51, thereby avoiding sewage retention in the washing and care chamber 2, effectively reducing the risk of odor generation and bacterial growth, improving the overall hygiene performance of the device, and ensuring that the washing and care process can be carried out continuously to meet the needs of multiple uses in a vehicle environment.

[0046] In one embodiment, the other end of the drain pipe 52 extends out of the vehicle body, allowing wastewater to be discharged directly outside the vehicle via the drain pipe 52. Wastewater generated in the washing and care chamber 2 can be efficiently discharged without remaining in the vehicle, thus preventing dampness, odors, and bacterial growth inside the vehicle, maintaining a clean and hygienic environment. This simplifies the wastewater discharge path, improves discharge efficiency and system reliability, and is particularly suitable for automatic washing and care operations during long-distance driving or multiple uses.

[0047] like Figure 3 As shown, in one embodiment, the sewage discharge mechanism 5 further includes a sewage collection tank 53; The sewage collection tank 53 is located between the washing and care chamber 2 and the sewage pump 51. The inlet of the sewage collection tank 53 is connected to the bottom of the washing and care chamber 2, and the outlet of the sewage collection tank 53 is connected to the sewage pump 51.

[0048] In this embodiment, the sewage discharge mechanism 5 also includes a sewage collection tank 53, which is located between the washing and care chamber 2 and the sewage pump 51 to temporarily collect sewage discharged from the washing and care chamber 2. Sewage flows into the collection tank through the inlet at the bottom of the washing and care chamber 2, where it is temporarily stored and buffered to prevent a large amount of sewage from flowing into the sewage pump 51 instantaneously, reducing the impact on the pump and pipeline and improving the stability of the system's sewage discharge. The outlet of the collection tank is connected to the sewage pump 51, which delivers the sewage to the sewage pipe 52 as needed. The sewage pipe 52 can extend directly out of the vehicle body to discharge the sewage outside, achieving safe sewage discharge. This design not only ensures efficient and smooth sewage discharge but also avoids pollution inside the vehicle, improving the safety and reliability of the onboard automatic handwashing device.

[0049] like Figure 1 and Figure 3 As shown, in one embodiment, the bottom of the washing and care chamber 2 is provided with a first inclined guide surface 21, and the washing and care chamber 2 is connected to the liquid inlet of the sewage collection tank 53 through the first inclined guide surface 21. The bottom of the sewage collection tank 53 is provided with a second inclined guide surface, and the sewage collection tank 53 is connected to the sewage pump 51 through the second inclined guide surface.

[0050] In this embodiment, a first inclined guide surface 21 is provided at the bottom of the washing and care chamber 2, and the washing and care chamber 2 is connected to the inlet of the sewage collection tank 53 through the first inclined guide surface 21. Sewage generated during the washing and care process can flow along the first inclined guide surface 21 to the sewage collection tank 53, preventing sewage from stagnating at the bottom of the washing and care chamber 2 and ensuring the cleaning effect and a clean and hygienic operating environment of the washing and care chamber 2. At the same time, it can reduce the corrosion or contamination of the inner wall of the washing and care chamber 2 by residual sewage, extend the service life of the device, and provide a reliable fluid basis for subsequent sewage discharge.

[0051] The bottom of the sewage collection tank 53 is provided with a second inclined guide surface, through which the sewage collection tank 53 is connected to the sewage pump 51. Through the second inclined guide surface, the sewage in the collection tank can be concentrated and flow into the sewage pump 51, achieving efficient sewage discharge. This not only improves sewage discharge efficiency and reduces the risk of sewage retention and secondary pollution, but also ensures the stability and reliability of the sewage discharge process. Combined with the intelligent management of the control module, automated discharge can be achieved, improving the sanitary environment inside the vehicle, enhancing user convenience and safety, and ensuring the long-term stable operation of the entire device.

[0052] In one embodiment, the drain pipe 52 may be connected to the vehicle's air conditioning condensate drain pipe or the windshield washer fluid recovery pipe.

[0053] In this embodiment, the sewage pipe 52 is connected to the vehicle's original drainage or recycling system, realizing the reuse of the sewage discharge path. There is no need to set up an additional independent drainage outlet, thereby simplifying the overall vehicle layout structure, reducing modification complexity, lowering installation costs, and improving system integration. It is especially suitable for application scenarios with limited vehicle space.

[0054] This embodiment, by connecting with the air conditioning condensate drain pipe or the windshield washer fluid recovery pipe, can utilize the vehicle's existing mature drainage path to achieve stable discharge or recycling of wastewater, which helps improve drainage reliability and reduce leakage risk. At the same time, it is beneficial to improve the collaborative working capability and long-term stability of the entire vehicle system, thereby further enhancing the practicality and engineering application value of this device in the vehicle environment.

[0055] like Figures 1-3 As shown, in one preferred embodiment, the vehicle-mounted automatic hand washing and care device can be installed on the armrest box.

[0056] In this embodiment, by taking advantage of the centrally located and easily accessible armrest box, the device is placed in a position that can be reached by both the driver and passengers, thereby improving ease of use. At the same time, the relatively concentrated internal space of the armrest box facilitates the integrated arrangement of the housing 1, washing and cleaning chamber 2, washing and cleaning actuator 4, and sewage discharge mechanism 5, reducing the occupation of other spaces in the vehicle and improving the overall space utilization of the vehicle.

[0057] Furthermore, by placing the device above or inside the armrest box, it can be installed and fixed using the existing structure of the armrest box, reducing the difficulty of modification and facilitating the centralized layout of water supply, sewage and electrical wiring, thereby improving system integration. At the same time, this location is far from the foot activity area, which can reduce the risk of accidental contact or contamination. Combined with the safety control of the interlocking mechanism 6, it helps to improve the overall safety and stability of use, thereby enhancing the user experience of the device in the actual vehicle environment.

[0058] In another embodiment, the in-vehicle automatic hand washing and care device can be installed on the interior door panel. By taking advantage of the fact that the door area is close to the range of hand movement of the occupants, users can conveniently use the device when getting in and out of the vehicle or while driving, thereby improving the immediacy and convenience of use. At the same time, the interior of the door has a certain space that can be used to arrange some pipes and modules, which is conducive to the decentralized layout of the structure and reduces the space occupied by the central control area. In addition, placing the device in the door position helps to guide the sewage pipe 52 to the outside of the vehicle nearby, simplifying the drainage path, improving sewage efficiency, and reducing the complexity of pipe layout.

[0059] In another embodiment, the in-vehicle automatic handwashing device can be installed in the rear passenger area of ​​the vehicle and near the trunk, allowing users to use it directly when the trunk is opened. By placing the device in a location where the rear passenger area is connected to or adjacent to the trunk, users can wash their hands directly with the trunk open after loading or unloading items, engaging in outdoor activities, or carrying goods, without having to enter the vehicle. This improves convenience and adaptability, making it particularly suitable for applications such as camping, fieldwork, or long-distance travel.

[0060] Furthermore, the washing and cleaning chamber 2 can be oriented towards the opening direction of the trunk, and the washing and cleaning actuator 4 and the sewage discharge mechanism 5 can be centrally arranged in conjunction with the rear space of the vehicle. This helps to shorten the sewage discharge path, allowing the sewage discharge pipe 52 to be guided to the outside of the vehicle nearby, improving sewage discharge efficiency and reducing the complexity of pipeline layout. At the same time, the rear seats and trunk area usually have a relatively spacious environment, which helps to reduce the impact on the passenger area inside the vehicle and avoid pollution problems. With the interlocking mechanism 6 and the safety control of the control module, safe and reliable washing and cleaning operations can be achieved when the trunk is open, thereby further enhancing the practicality and multi-scenario application capabilities of the device.

[0061] In one embodiment, the sensing unit 3 may be one or more combinations of an infrared sensor, a capacitive sensor, a pressure sensor, or a microwave sensor.

[0062] In this embodiment, the sensing unit 3 can be any one of an infrared sensor, a capacitive sensor, a pressure sensor, or a microwave sensor. When using an infrared sensor, non-contact triggering can be achieved by detecting changes in infrared radiation generated when a hand approaches; when using a capacitive sensor, high-sensitivity detection can be achieved by sensing changes in the electric field caused by a hand approaching; when using a pressure sensor, the washing and care process can be triggered by detecting pressure signals generated by hand contact or pressing; when using a microwave sensor, dynamic recognition can be achieved by detecting minute movements of the hand. This embodiment uses a single type of sensor, resulting in a simple structure, low cost, and easy selection of appropriate detection methods according to specific application scenarios, thereby meeting basic automatic triggering requirements while ensuring good system response performance and stability.

[0063] The sensing unit 3 in this embodiment can also be configured as a combination of multiple sensors. For example, a combination of an infrared sensor and a microwave sensor can be used, where the infrared sensor is used for rapid trigger detection of the approach of the hand, and the microwave sensor is used for continuous tracking and identification of dynamic changes of the hand, thereby improving the continuity and stability of detection; a combination of a capacitive sensor and an infrared sensor can also be used, where the capacitive sensor detects the change in electric field caused by the approach of the hand, and the infrared sensor is used for secondary confirmation, thereby reducing the probability of false triggering; Furthermore, a pressure sensor can be positioned in the support position within the washing and care chamber 2. When hand contact or pressure is detected, the washing and care process is triggered, making it suitable for application scenarios that require contact triggering. In addition, a capacitive sensor can be combined with a pressure sensor to achieve hierarchical triggering control through a combination of non-contact and contact detection. For example, the system can be woken up first by a capacitive sensor, and then the execution can be confirmed by a pressure sensor, thereby improving the precision of control.

[0064] In one embodiment, the interlocking mechanism 6 can be a magnetic switch or a photoelectric sensor.

[0065] In this embodiment, when the interlocking mechanism 6 uses a magnetic switch, the open or closed state of the cover can be detected by setting a magnetic element and a sensing element between the wash cover 11 or maintenance cover 12 and the housing 1. The structure is simple and highly stable. When the interlocking mechanism 6 uses a photoelectric sensor, the position of the cover can be determined by detecting changes in the obstruction or reflection of light signals. This has the advantages of fast response speed and high detection accuracy. Real-time monitoring of the open state of the wash cover 11 and maintenance cover 12 is achieved, and the detection results are fed back to the control module to restrict the start of the wash actuator 4 when the cover is not closed properly. This effectively avoids safety hazards caused by misoperation and improves the safety and reliability of the device.

[0066] like Figure 3 As shown, in one embodiment, an in-vehicle automatic hand washing and care device further includes a status indication module 7; The status indicator module 7 includes a status indicator light 71 for indicating the status of the washing and care chamber 2, the washing and care execution status, the sewage discharge status, and the safety status; Status indicator 71 is connected to the control module via communication.

[0067] In this embodiment, the status indicator light 71 can display in real time whether the washing and care chamber 2 is open, whether the washing and care actuator 4 is working, whether the sewage discharge process is completed, and whether the vehicle meets the safe washing and care conditions through different colors or flashing patterns. When the user's hand approaches the washing and care chamber 2, the status indicator light 71 can intuitively indicate whether the current operation can be performed. If the washing and care cover 11 is not opened or the vehicle's driving condition is unsafe, the status indicator light 71 will display a warning message to prompt the user to prohibit operation. When the washing and care process starts normally, clean water or soap is supplied, and the drying module 43 is working, the status indicator light 71 displays the operating status, intuitively indicating the working status of each module of the system.

[0068] In this embodiment, by setting the status indicator module 7, users and maintenance personnel can quickly understand the system's operating status, avoid misoperation, and facilitate monitoring and maintenance, thereby improving the safety, convenience, and reliability of the hand washing and care operation and effectively enhancing the user experience of the vehicle-mounted automatic hand washing and care device.

[0069] Embodiments of this application also provide a control method for an in-vehicle automatic hand washing and care device, used in an in-vehicle automatic hand washing and care device as described in any of the preceding embodiments.

[0070] like Figure 4 The diagram shows a flowchart of a control method for an in-vehicle automatic hand washing and care device, including: Step S401: Obtain the working status of the interlocking mechanism; Step S402A: If the interlocking mechanism locks the washing and care chamber or unlocks the washing and care actuator, the washing and care operation is prohibited. Step S402B: If the interlocking mechanism unlocks the washing and care chamber and locks the washing and care execution mechanism, then obtain the hand detection signal from the sensing and detection unit; Step S403: When the hand detection signal indicates that a hand has entered the washing and care chamber, acquire the driving status signal; Step S404: Determine whether the vehicle meets the safety conditions based on the driving status signal. If the safety conditions are met, control the washing and care actuator to enter the washing and care process. Step S405: After the washing and care process has been executed for the set time, control the sewage discharge mechanism to discharge the sewage.

[0071] Specifically, in step S401, the status information of the interlocking mechanism 6 is first obtained to determine the locking or unlocking status of the washing and care chamber 2 and the washing and care actuator 4. In step S402A, if the interlocking mechanism 6 indicates that the washing and care chamber 2 is locked or the washing and care actuator 4 is unlocked, the system prohibits the washing and care operation, thereby avoiding misoperation and potential safety hazards. In step S402B, when the interlocking mechanism 6 indicates that the washing and care chamber 2 is unlocked and the washing and care actuator 4 is locked, the control module will activate the sensing detection unit 3 to obtain the hand detection signal from the sensing detection unit 3 and detect whether a hand has entered the washing and care chamber 2.

[0072] In step S403, when a hand detection signal indicates that a hand has entered the washing and care chamber, meaning that hand entry into washing and care chamber 2 is detected, the system acquires the vehicle's driving status signal and, in step S404, determines whether the vehicle meets safety conditions, such as being stationary or in a driving state where washing and care are permitted. If the safety conditions are met, the system activates the washing and care execution mechanism 4, including the water supply module 41, soap supply module 42, and drying module 43, to complete hand washing, soap application, rinsing, and drying operations in a preset sequence. Finally, in step S405, after the washing and care process has been executed for a set time, the system controls the sewage discharge mechanism 5 to discharge the wastewater generated during the washing and care process through the sewage collection tank 53 and the sewage pipe 52, ensuring a clean environment inside the vehicle and preventing wastewater pollution. By combining interlocking with the vehicle's driving status for judgment, the washing and care operation is automated, intelligent, and safe.

[0073] Specifically, when the interlocking mechanism 6 indicates that the washing chamber 2 is locked or the washing actuator 4 is unlocked, if the washing operation is still performed, the washing chamber 2 may be accidentally opened or the actuator may be exposed, posing a safety hazard of pinching hands or liquid leakage. Therefore, the system prohibits the washing operation.

[0074] When the interlocking mechanism 6 indicates that the washing chamber 2 is unlocked and the washing actuator 4 is locked, it means that the device is in a safe operating state. Only then is it necessary to further obtain the hand detection signal from the sensing unit 3 to detect whether a hand has entered the washing chamber 2, so as to avoid starting the washing process when no one is operating or the hand is not in place, thus preventing waste of water and ensuring the accuracy and safety of the washing action. The combination of interlocking status and hand detection ensures that the device is both safe and efficient when used in the vehicle.

[0075] In one embodiment, the driving status signal includes a vehicle speed signal, a steering angle signal, and an acceleration signal; Determining whether a vehicle meets safety conditions based on driving status signals specifically includes: The safety conditions are met if the vehicle speed signal is less than or equal to the preset vehicle speed threshold, the absolute value of the steering angle signal is less than or equal to the preset steering angle threshold, and the absolute value of the acceleration signal is less than or equal to the preset acceleration threshold.

[0076] In this embodiment, by acquiring the vehicle's speed, steering angle, and acceleration signals in real time, the control module can determine whether the vehicle is in a safe state suitable for automatic hand washing. When the vehicle speed signal is less than or equal to a preset speed threshold, the absolute value of the steering angle signal is less than or equal to a preset steering angle threshold, and the absolute value of the acceleration signal is less than or equal to a preset acceleration threshold, the vehicle is determined to be stationary or in a stable state, meeting the safety conditions. The system then allows the washing process to begin, thereby ensuring the safety of occupants and the device during the washing process. Conversely, when any signal exceeds the preset threshold, the vehicle may be in motion, making a sharp turn, or accelerating / decelerating. The system automatically prohibits the washing operation, thereby avoiding the risk of liquid splashing, device damage, or occupant injury.

[0077] In one preferred embodiment, the preset vehicle speed threshold can be 5 km / h, the absolute value of the preset steering angle threshold can be 15°, and the absolute value of the preset acceleration threshold can be 0.3g. When the vehicle meets the above conditions, the control module allows the washing and care process to start; if any preset threshold is exceeded, the washing and care operation is prohibited. The system achieves safety protection control in the vehicle environment, enabling the washing and care device to work safely and reliably in a stationary or stable state, while improving the user experience.

[0078] like Figure 3As shown, in one embodiment, a function selection button 13 is provided on the housing 1. The function selection button 13 is communicatively connected to the control module. The function selection button 13 is used to switch between different washing and care modes, including a deep cleaning mode and a quick drying mode. Users can select the start / stop of the soap cleaning process and the drying module 43 by pressing the function selection button 13 once or multiple times. For example, a short press switches whether deep cleaning is enabled, and a long press or continuous press switches whether quick drying is enabled, thus flexibly adjusting the washing and care process according to actual needs.

[0079] In another embodiment, the control module is communicatively connected to the vehicle's central control system. Customers can select modes via the in-vehicle display or control interface, and configure whether to enable deep cleaning and quick drying functions on the central control interface. This embodiment, through its integration with the in-vehicle system, enables unified control and information interaction, enhancing the system's intelligence and facilitating collaborative management with other vehicle functions, thereby further improving safety and convenience.

S505: If the vehicle speed signal is less than or equal to the preset vehicle speed threshold, the absolute value of the steering angle signal is less than or equal to the preset steering angle threshold, and the absolute value of the acceleration signal is less than or equal to the preset acceleration threshold, the safety conditions are met. S506: Determine the cleaning mode based on washing and care needs; S507A: In deep cleaning mode, the four-way distribution valve is controlled to connect to the soap supply module, and the first electric pump is started to supply soap to the washing and care chamber in a metered manner. S507B: If in normal cleaning mode, proceed to step 508; S508: Controls the four-way distribution valve to connect to the water supply module, starting the second electric pump to supply clean water to the washing and care chamber for rinsing; S509: Determine whether the rapid drying mode is activated; S510A: In rapid drying mode, control the four-way distribution valve to switch to the air drying module, and start the fan and heating element for hot air drying; S510B: If it is not in rapid drying mode, proceed to step S511; S511: After the washing and care process has been executed for the set time, the control sewage discharge mechanism starts the sewage pump to discharge the sewage in the washing and care chamber and sewage collection tank through the sewage discharge pipe, thus completing the sewage discharge operation; at the same time, all motors are stopped and the four-way distribution valve is reset.
