[0040] In this embodiment, the self-cleaning car door handle system includes a door handle base, a door handle handle, a first nozzle, a supply pipe, and a cleaning medium supply module.

[0041] Reference Figure 1 The door handle mount is installed on the car body, specifically on the door to be controlled, or on the B-pillar, C-pillar, or other locations near the door to be controlled.

[0042] Reference Figure 2 The door handle base has a receiving space, and part or all of the door handle handle is located in the receiving space of the door handle base. One end of the door handle handle is connected to the door handle base through a hinge or other structure. The driver or passenger can put their hand into the receiving space of the door handle base and move the door handle handle to trigger the mechanical structure or sensor connected to the door handle handle, thereby generating an action or signal to open or close the door.

[0043] Reference Figure 3 and Figure 4 The door handle base is equipped with a first nozzle. The first nozzle can also be located on the door handle itself. (See reference...) Figure 1 One end of the supply pipe is connected to the door handle seat and to the inlet of the first nozzle, while the other end of the supply pipe is connected to the cleaning medium supply module.

[0044] In this embodiment, the cleaning medium supply module can be installed in the engine compartment, under the seats, or in the trunk of the vehicle. The supply pipe is laid out according to the vehicle's piping, connecting the cleaning medium supply module to the first nozzle. The cleaning medium supply module stores cleaning medium and outputs it through its outlet, allowing the cleaning medium to reach the first nozzle through the supply pipe, enter the first nozzle from its inlet, and be sprayed out by the first nozzle to the door handle seat and door handle handle.

[0045] In this embodiment, by setting up a cleaning medium supply module and supply pipe, and installing a first nozzle at the door handle seat or door handle position, the cleaning medium supply module can supply cleaning medium to the door handle seat and door handle. The cleaning medium can wash away dust, mud, and other contaminants adhering to the door handle seat and door handle, keeping the surface of the door handle seat and door handle clean, so that the driver or passenger's hands are not contaminated when using the door handle to open and close the car door, thus improving the driving and riding experience. On the other hand, in situations where multiple people are in the car or the car is used for commercial purposes, the cleaning medium can also remove pathogens and other substances left by the driver or passenger when using the door handle, keeping the door handle seat and door handle hygienic and protecting the health of the driver and passengers. Moreover, the cleaning medium can also remove fingerprints and other information left by the driver or passenger when using the door handle, reducing the risk that criminals will collect fingerprints on the door handle or door handle seat for improper purposes, thus ensuring the safety of car use.

[0046] In this embodiment, refer to Figure 5 The car door handle system also includes a dry gas supply module, a gas pipe, and a second nozzle. (Refer to...) Figure 3 and Figure 4 The second nozzle can be located on the door handle base or on the door handle itself. (See reference...) Figure 5 One end of the gas supply pipe is connected to the door handle seat and then to the inlet of the second nozzle. The other end of the gas supply pipe is connected to the dry gas supply module.

[0047] In this embodiment, the drying gas supply module can be installed in the engine compartment, under the seats, or in the trunk of the vehicle. The gas supply pipe is laid out according to the vehicle's piping, connecting the drying gas supply module to the second nozzle. The drying gas supply module can be a device such as an air pump. It pumps out drying gas, such as air, through its output port, allowing the drying gas to reach the second nozzle via the gas supply pipe. The drying gas then enters the second nozzle through its input port and is ejected by the second nozzle to the door handle base and door handle handle. Specifically, the drying gas can refer to its purpose of drying the door handle base and door handle handle; it is not necessary for the drying gas to reach a specific level of dryness.

[0048] In this embodiment, the cleaning medium supply module can generate a task completion trigger signal after outputting the cleaning medium, and send the task completion trigger signal to the drying gas supply module. Upon receiving the task completion trigger signal from the cleaning medium supply module, the drying gas supply module begins operation.

[0049] By setting up a dry gas supply module, a gas delivery pipe, and a second nozzle, and controlling the dry gas supply module to output dry gas after the cleaning medium supply module outputs the cleaning medium, the surface of the door handle seat and door handle can be dried by the dry gas when the cleaning medium is in liquid state, providing a comfortable use environment for the driver or passenger and improving the driving experience.

[0050] In this embodiment, the car door handle system also includes an environmental sensing module and a control module. Specifically, an electronic control unit (ECU) or similar device can be used as the control module; the environmental sensing module can be a sensor or sensor group that detects environmental parameters such as rainfall, humidity, and wind speed.

[0051] An environmental sensing module can be installed in locations such as a car's rearview mirror to detect the external environment, thereby obtaining environmental parameters such as rainfall, humidity, and wind speed. The environmental sensing module then sends this information to the control module.

[0052] After receiving environmental parameter information, the control module determines whether the environmental parameter information meets a first preset condition. Specifically, the first preset condition can be specific weather conditions. For example, the first preset condition includes multiple thresholds that match environmental parameters such as rainfall, humidity, and wind speed. The control module compares the rainfall, humidity, and wind speed in the environmental parameter information with the corresponding thresholds to determine the levels of rainfall, humidity, and wind speed, and then determines the current weather based on these levels. For example, if the rainfall is low, the humidity is high, and the wind speed is low, the control module can determine that it is currently experiencing the plum rain season. The control module can then generate trigger signals at a high frequency and send each generated trigger signal to the cleaning medium supply module, thereby enabling the cleaning medium supply module to operate at a high frequency. This means that the door handle base and door handle can be frequently cleaned with cleaning medium, effectively addressing potential mud contamination in the plum rain season. Based on the same principle, when the control module determines that the current weather is dry, it generates a trigger signal at a higher frequency, which causes the cleaning medium supply module to work at a higher frequency, thus effectively dealing with possible dust pollution in dry weather conditions. When the control module determines that the current weather is rainy, it generates a trigger signal at a lower frequency or even stops generating a trigger signal, which causes the cleaning medium supply module to work at a lower frequency or even stop working, thus avoiding the waste of cleaning medium when cleaning is unnecessary or the cleaning medium cannot function in rainy conditions.

[0053] In this embodiment, the car door handle system also includes a driving sensing module. Specifically, the driving sensing module can be an acceleration sensor or a sensor array, which can detect the acceleration of the car in the left-right, up-down, and other directions, and send the driving status information to the control module as driving status information.

[0054] After receiving the driving status information, the control module determines whether the driving status information meets a second preset condition. Specifically, the second preset condition can be a specific road shape or road surface environment. For example, the second preset condition includes a threshold matching the vertical acceleration. The control module compares the vertical acceleration in the driving status information with the corresponding threshold to determine the level of vertical acceleration and judges the current road surface environment based on the level of vertical acceleration. For example, if the vertical acceleration is large, the control module can determine that it is currently on a bumpy road surface. The control module can generate trigger signals at a higher frequency and send each generated trigger signal to the cleaning medium supply module, thereby causing the cleaning medium supply module to work at a higher frequency. This means that the door handle base and door handle can be cleaned frequently with cleaning medium, effectively dealing with possible mud or dust pollution in bumpy road environments. Based on the same principle, when the control module determines that it is currently on a smooth road surface, the control module generates trigger signals at a lower frequency or even stops generating trigger signals, thereby causing the cleaning medium supply module to work at a lower frequency or even not work, thus avoiding waste of cleaning medium when cleaning is not needed on smooth roads.

[0055] In this embodiment, the car door handle system also includes a positioning module and a disinfectant dispensing module. Specifically, the positioning module can locate the car using satellite positioning or other means to obtain location information. The disinfectant dispensing module can be installed near the cleaning medium supply module or integrated inside the disinfectant dispensing module. The disinfectant dispensing module stores disinfectant and can output disinfectant to the output port or supply pipe of the cleaning medium supply module, thereby allowing the disinfectant to be added into the supply pipe and mixed with the cleaning medium, and finally sprayed together from the first nozzle onto the surface of the door handle seat and door handle handle. Specifically, the disinfectant can be a stock solution containing active ingredients such as p-chloro-meta-xylenol or polyhexamethylene biguanide.

[0056] In this embodiment, the positioning module is configured with several preset areas, which can specifically represent locations such as hospitals, sanatoriums, or farms. Based on the detected positioning information, the positioning module determines in real time whether the vehicle has entered these preset areas. When the positioning module detects that the positioning information is within a preset area, it generates trigger information and sends it to the disinfectant dispensing module.

[0057] After receiving the trigger information sent by the positioning module, the disinfectant dispensing module adds disinfectant to the supply tube or the cleaning medium supply module, so that the disinfectant is added into the supply tube and mixed with the cleaning medium, and finally sprayed out from the first nozzle onto the surface of the door handle seat and the door handle handle.

[0058] In this embodiment, by setting up a positioning module and a disinfectant dispensing module, disinfectant can be added to the cleaning medium when the car passes through areas where there is a high probability of high concentrations of pathogens in the air, such as hospitals, sanatoriums, or farms. This disinfectant is diluted by the cleaning medium and sprayed onto the surfaces of the door handle base and handle, disinfecting these surfaces, maintaining their hygiene, and reducing the concentration of pathogens on their surfaces, thus helping to prevent the spread of infectious diseases. The positioning module can trigger the disinfectant dispensing module in real time, so disinfection of the door handle base and handle surfaces can be carried out in real time, thereby reducing the time pathogens remain on the surfaces and decreasing the possibility of pathogen spread or increased concentration due to reproduction.

[0059] In this embodiment, the car door handle system also includes a temperature control module. Specifically, the temperature control module can be a semiconductor cooling device and a heating device. The temperature control module can be integrated with the cleaning medium supply module, or the temperature control module can have two sets of semiconductor cooling chips and semiconductor heating chips. One semiconductor cooling chip wraps around the supply pipe, and the semiconductor heating chip in the same set is connected to a heat sink. The other semiconductor heating chip wraps around the supply pipe, and the semiconductor cooling chip in the same set is connected to another heat sink. When the semiconductor cooling chip wrapping the supply pipe cools, the semiconductor heating chip wrapping the supply pipe stops heating, thereby heating the cleaning medium in the supply pipe. When the semiconductor heating chip wrapping the supply pipe heats, the semiconductor cooling chip wrapping the supply pipe stops cooling, thereby cooling the cleaning medium in the supply pipe, thus achieving temperature regulation of the cleaning medium.

[0060] In this embodiment, a target temperature can be set in the control unit of the temperature control module (for example, 10°C in summer and 40°C in winter). The temperature sensing unit in the temperature control module detects the air temperature outside the car body to obtain the current air temperature information. The current air temperature information is compared with the target temperature. When the current air temperature information is higher than the target temperature, the temperature control module cools the cleaning medium through a semiconductor cooling chip; when the current air temperature information is lower than the target temperature, the temperature control module heats the cleaning medium through a semiconductor heating chip.

[0061] In this embodiment, by setting a temperature control module, the current air temperature information can be detected, and it can be assumed that the temperature of the cleaning medium stored in the cleaning medium supply module is the same as the current air temperature information. By heating or cooling the cleaning medium, the temperature of the cleaning medium sprayed onto the door handle seat and door handle can be made close to the target temperature. Therefore, by setting a target temperature that is comfortable for the human body, the cleaning medium sprayed onto the door handle seat and door handle can have a suitable temperature before the driver or passenger uses the door handle, so that the door handle seat and door handle can provide a good tactile feel to the driver or passenger and improve the driving experience.

[0062] In this embodiment, the cleaning medium supply module can be equipped with a storage unit and a pumping unit. The storage unit stores liquid cleaning medium, such as pure water, medical alcohol, or disinfectant solution. The pumping unit pumps the cleaning medium from the storage unit to the supply pipe. Specifically, a storage tank can be used as the storage unit, and a water pump can be used as the pumping unit. The storage unit has a replenishment port, and the liquid cleaning medium can be used as a consumable. When the consumption reaches a certain level, cleaning medium can be replenished to the storage unit through the replenishment port.

[0063] In this embodiment, the cleaning medium supply module can be equipped with an air compression unit and an air storage unit. The air compression unit obtains air from the outside and compresses it to obtain compressed air. A high-pressure airbag is used as the air storage unit to store the compressed air. The high-pressure airbag can be made of rubber or similar material, and the pressure of the stored compressed air can be 2-3 bar. In the event of an accident causing the high-pressure airbag to explode, the resulting damage is relatively small. The high-pressure air released by the air storage unit can be used as a cleaning medium and released into the supply pipe. Finally, it is sprayed from the first nozzle onto the surface of the door handle seat and door handle, thereby cleaning the surface of the door handle seat and door handle. Since the air compression unit can obtain air anytime and anywhere, the cleaning medium is not a consumable and does not need to be replenished, which is convenient for users to use and maintain.

[0064] In this embodiment, the cleaning medium supply module can be equipped with an ice maker and an ice storage unit. The ice maker generates small ice particles, which are stored in the ice storage unit. Using the ice particles as a solid cleaning medium, the ice particles are finally sprayed out from the first nozzle. The ice particles impact and clean the surfaces of the door handle seat and the door handle handle, thereby achieving a better cleaning effect.

[0065] In this embodiment, the car door handle system includes a rotary retainer, wherein the stator of the rotary retainer is mounted on the door handle seat, and the rotor is connected to the door handle handle, so that the door handle handle can be turned not only in the manner of entering and leaving the receiving space, but also as described above. Figure 6 Within the containment space, it rotates about its own extension direction as an axis.

[0066] By using a rotating retainer to install the door handle, the door handle can rotate within the receiving space, allowing any part of the side of the door handle to rotate into the receiving space and directly contact the cleaning medium sprayed from the first nozzle, thus achieving a cleaning effect on different parts of the door handle.

[0067] The car door handle system in this embodiment can be manufactured separately and installed on the car body during later maintenance, or it can be installed on the car body during the car production process and used as a whole with other car components.
