[0030] The accompanying drawings are intended to provide a further understanding of the application, and constitute a part of the specification, together with the embodiments of the application, to explain the application, and do not constitute a limitation on the application. In the drawings: Figure 1 A flow chart of a method for refilling wiper fluid in an embodiment of the present application; Figure 2 A block diagram of a wiper fluid refilling device in an embodiment of the present application; Figure 3 A schematic diagram of the hardware structure of a wiper fluid refilling system in an embodiment of the present application. DETAILED DESCRIPTION

[0031] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, it should be understood that the preferred embodiments described here are only used to illustrate and explain the present application, and are not used to limit the present application.

[0032] Figure 1 A flow chart of a method for refilling wiper fluid in an embodiment of the present application, as shown in Figure 1 The method can be implemented as the following steps S101-S103: In step S101, when the vehicle meets the wiper fluid refilling condition, the condensed water in the condensed water storage assembly is delivered to the wiper washing jug through the wiper fluid communication assembly, wherein the condensed water is air conditioning condensed water; In step S102, the concentrated liquid is delivered into the wiper washing jug through the wiper fluid providing assembly, wherein the delivery amount of the concentrated liquid depends on the target concentration of the wiper fluid and the delivery amount of the condensed water; In step S103, the automatic mixing and dilution of the condensed water and the concentrated liquid in the wiper washing jug is realized, and the wiper fluid preparation is completed.

[0033] In the present application, when the vehicle meets the wiper fluid refilling condition, the condensed water in the condensed water storage assembly is delivered to the wiper washing jug through the wiper fluid communication assembly, wherein the condensed water is air conditioning condensed water; A liquid level sensor is installed on the vehicle, which is arranged in the wiper washing jug and can monitor the liquid level height in the wiper washing jug in real time. When the liquid level sensor detects that the liquid level in the wiper washing jug is lower than the pre-set minimum liquid level threshold, it indicates that the wiper fluid is insufficient, which meets one of the refilling conditions.

[0034] In addition, when the vehicle is parked for a long time or parked at night, a timing task can be set to automatically collect condensed water and prepare wiper fluid at a specific time (such as early morning or before the vehicle starts again) to ensure that the liquid level in the wiper washing jug is sufficient before each driving. Secondly, weather forecast information can also be combined. Under the weather conditions of rainy days or high humidity, the system can predict that the windshield cleaning demand will increase, so as to start the condensed water collection and wiper fluid preparation in advance to ensure that sufficient wiper fluid can be provided in time when needed.

[0035] At the same time, the intelligent control system of the vehicle obtains the running state information of the vehicle, such as whether the vehicle is in the starting and stable running state. Only when the vehicle is started and stably runs for a period of time (such as 5-10 minutes), it is ensured that the air conditioning system normally operates to produce condensate water, and the vehicle is in a safe state (such as non-emergency braking, non-high-speed driving, and other special dangerous states) that can be refueled, it is considered to meet the refueling conditions.

[0036] The condensate water in the condensate water storage assembly is collected by a condensate water collection assembly, wherein the water inlet of the condensate water collection assembly is sealingly connected to the air conditioning condensing pipe through a hose, and the water inlet is located higher than the water outlet of the condensate water storage assembly. The difference in gravity is used to realize the natural flow of condensate water into the storage assembly, and the drain is arranged at the lowest point of the bottom of the storage assembly to remove excess moisture.

[0037] The rainwater and wiper water communication assembly includes a three-way valve structure, and the condensate water in the condensate water storage assembly is transported to the wiper washing kettle through the rainwater and wiper water communication assembly, which includes: The first control valve of the three-way valve structure is automatically opened or closed according to the liquid level height in the condensate water storage assembly, so as to control the timing and amount of condensate water transported to the wiper washing kettle through the opening or closing of the first control valve. A one-way valve is arranged in the pipeline between the condensate water storage assembly and the washing kettle to prevent the liquid in the washing kettle from flowing back to the condensate water storage assembly.

[0038] Specifically, the first control valve of the three-way valve structure is automatically opened or closed according to the liquid level height in the condensate water storage assembly, which includes: when the liquid level in the condensate water storage assembly reaches a first preset liquid level, the first control valve is controlled to be closed to stop the transportation of condensate water; when the liquid level is lower than a second preset liquid level, the first control valve is controlled to be opened to supplement condensate water to the condensate water storage assembly.

[0039] The rainwater and wiper water communication assembly includes a three-way valve structure, and the condensate water in the condensate water storage assembly is transported to the wiper washing kettle through the rainwater and wiper water communication assembly, which includes: The condensate water in the condensate water storage assembly is collected by a condensate water collection assembly, wherein the water inlet of the condensate water collection assembly is sealingly connected to the air conditioning condensing pipe through a hose, and the water inlet is located higher than the water outlet of the condensate water storage assembly. The difference in gravity is used to realize the natural flow of condensate water into the storage assembly, and the drain is arranged at the lowest point of the bottom of the storage assembly to remove excess moisture.

[0040] The target concentration of the wiper water is preset in the intelligent control system of the vehicle, which can be adjusted according to different use scenarios and needs, for example, in the summer, the concentration of the wiper water can be appropriately increased to enhance the cleaning effect in the area with more dust; in winter, in order to prevent the wiper water from freezing at low temperature, the concentration can be reduced and antifreeze ingredients can be added.

[0041] According to the principle of chemical mixing, a calculation model is established between the concentrated liquid delivery volume and the target concentration of the wiper water and the condensed water delivery volume. Assuming that the target concentration of the wiper water is C (volume fraction), the delivery volume of the condensed water is V1, the delivery volume of the concentrated liquid is V2, and the original concentration of the concentrated liquid is C0 (a known fixed value), then there is the formula C = (V2 × C0) / (V1 + V2). Through the calculation module in the intelligent control system, the required concentrated liquid delivery volume V2 is calculated according to the real-time obtained condensed water delivery volume V1 and the preset target concentration C.

[0042] According to the calculated concentrated liquid delivery volume V2, a control signal is sent to the second control valve to adjust the opening of the second control valve, so that the concentrated liquid enters the wiper washing kettle through the delivery pipeline with accurate flow rate.

[0043] During the delivery of the concentrated liquid, a flow sensor is installed on the delivery pipeline to monitor the actual delivery flow rate of the concentrated liquid in real time, and the monitoring data is fed back to the intelligent control system. The intelligent control system compares the actual delivery flow rate with the calculated theoretical delivery volume, and if there is a deviation, the opening of the flow control valve is adjusted in time to ensure the accuracy of the delivery volume of the concentrated liquid. When the delivery volume of the concentrated liquid reaches the calculated value V2, the intelligent control system sends a stop signal to the delivery pump and the flow control valve to stop the delivery of the concentrated liquid.

[0044] The automatic mixing and dilution of the condensed water and the concentrated liquid is realized in the wiper washing kettle, and the preparation of the wiper water is completed.

[0045] A stirring device is provided in the wiper washing kettle, which can be an electric stirrer. The stirring blades of the stirrer are designed in a suitable shape, such as propeller or multi-blade, to increase the stirring effect. The motor of the stirrer is installed outside the wiper washing kettle and connected to the stirring blades inside the kettle through a sealed shaft to prevent the wiper water from leaking into the motor.

[0046] A reasonable flow channel structure is designed inside the wiper washing kettle to guide the condensed water and the concentrated liquid to quickly converge and start mixing after entering the wiper washing kettle. For example, a guide plate is provided at the outlet of the condensed water delivery pipeline and the concentrated liquid delivery pipeline to make the two liquids collide with each other at a certain angle and speed, promoting preliminary mixing.

[0047] When the condensed water and the concentrated liquid are delivered to the wiper washing kettle, the intelligent control system of the vehicle sends a start signal to the motor of the stirring device, and the stirrer starts to work at a set speed (such as 100-300 revolutions per minute) to stir the liquid in the kettle. The stirring time is pre-set according to the volume of the wiper washing kettle and the stirring effect, generally 30-60 seconds, to ensure that the condensed water and the concentrated liquid are fully mixed and uniform.

[0048] The concentration sensor is installed in the wiper washing kettle to monitor the actual concentration of the wiper water in real time. The intelligent control system compares the actual concentration with the preset target concentration. If the deviation between the actual concentration and the target concentration is within the allowed range (e.g. ±5%), it is considered that the mixing is completed; if the deviation exceeds the allowed range, the intelligent control system adjusts the stirring time or recalculates the concentrated liquid delivery amount and performs supplementary delivery, and then performs stirring and mixing again until the actual concentration of the wiper water reaches the target concentration requirement.

[0049] When the wiper water preparation is completed, the intelligent control system displays the information that the wiper water preparation is completed to the driver through the instrument panel or the central control display screen of the vehicle, and can also issue a prompt sound to remind the driver. In addition, the intelligent control system also records the relevant data of this wiper water preparation, such as the condensed water delivery amount, the concentrated liquid delivery amount, the preparation time, etc., for subsequent analysis and optimization.

[0050] The wiper water automatic filling method of the present application can automatically start the filling process when the vehicle meets the filling conditions, without the need for manual filling, and can also ensure that the wiper washing water always maintains a sufficient state, thereby avoiding the situation that the driving vision is affected due to insufficient washing water, and improving the wiper water filling efficiency and driving safety. Secondly, the present application uses the condensed water generated during the operation of the vehicle air conditioning system as a supplementary water source for the wiper water, which not only reduces the dependence on external water sources, but also realizes the recycling of water resources, achieving the purpose of saving water resources.

[0051] In one embodiment, the condensed water in the condensed water storage assembly is collected by a condensed water collection assembly, wherein the water inlet of the condensed water collection assembly is sealingly connected to the air conditioning condensing pipe through a hose, and the water inlet position is higher than the water outlet of the condensed water storage assembly. The condensed water naturally flows into the storage assembly by utilizing the difference in gravity, and the drain is arranged at the lowest point of the bottom of the storage assembly to drain excess moisture.

[0052] The beneficial effects of the present embodiment are that the water inlet of the condensed water collection assembly is sealingly connected to the air conditioning condensing pipe through a hose, and the water inlet position is higher than the water outlet of the condensed water storage assembly, so that the condensed water can be naturally flowed in by utilizing the difference in gravity, without the need for additional motors, simplifying the collection process and reducing energy consumption. Secondly, the arrangement of the drain effectively prevents water accumulation in the storage assembly, ensuring the quality of the condensed water.

[0053] In one embodiment, the wiper water communication assembly includes a three-way valve structure, and the above step S101 can be implemented as the following steps: The first control valve of the three-way valve structure is automatically opened or closed according to the liquid level in the condensate water storage assembly, so as to control the timing and amount of condensate water delivery to the wiper washing kettle through the opening or closing of the first control valve, wherein a one-way valve is arranged in the pipeline between the condensate water storage assembly and the washing kettle to prevent the liquid in the washing kettle from flowing back to the condensate water storage assembly.

[0054] The embodiment has the beneficial effect that the precise control of the condensate water flow is realized through the three-way valve structure and the automatic control of the liquid level. The arrangement of the one-way valve effectively prevents the liquid in the washing kettle from flowing back, ensuring the stability and reliability of the system.

[0055] In one embodiment, the first control valve of the three-way valve structure is automatically opened or closed according to the liquid level in the condensate water storage assembly, which can be implemented as steps A1-A2: In step A1, when the liquid level in the condensate water storage assembly reaches a first preset liquid level, the first control valve is controlled to be closed to stop the delivery of condensate water; In step A2, when the liquid level is lower than a second preset liquid level, the first control valve is controlled to be opened to supplement the condensate water to the condensate water storage assembly.

[0056] The embodiment has the beneficial effect that the automatic management of condensate water delivery is realized through the automatic monitoring and control of the liquid level, reducing manual intervention. The control valve is automatically opened or closed according to the liquid level, effectively optimizing the storage space of the condensate water and avoiding waste.

[0057] In one embodiment, the concentrated liquid tank of the wiper water providing assembly is connected to the wiper washing kettle through a second control valve, and the above step S102 can be implemented as the following steps: The opening degree of the second control valve is dynamically adjusted according to the signal feedback of the environmental temperature sensor to control the delivery amount of the concentrated liquid, and the second control valve is automatically closed after the delivery is completed.

[0058] The embodiment has the beneficial effect that the delivery amount of the concentrated liquid is dynamically adjusted according to the environmental temperature, ensuring the applicability of the wiper water in different environments.

[0059] In one embodiment, the wiper washing kettle is internally provided with a stirring paddle structure, and the above step S103 can be implemented as the following steps B1-B4: In step B1, the vibration energy when the vehicle is running or a micro motor is used to drive the stirring paddle to rotate; In step B2, the concentration sensor arranged in the kettle is used to monitor the concentration of the mixed liquid in real time; In step B3, when the concentration is within a preset range, it is determined that the wiper water preparation is completed; In step B4, when the concentration deviates from the preset range, the concentration adjustment process is performed.

[0060] The beneficial effect of the embodiment is that the uniform mixing of condensed water and concentrated liquid is promoted by the stirring paddle structure or vehicle vibration energy, and the quality of the wiper water is improved. The real-time monitoring and adjustment of the mixed liquid concentration are realized by the concentration sensor, and the stability of the wiper water concentration is ensured.

[0061] In one embodiment, the above step B4 can be implemented as the following steps C1-C3: In step C1, when the concentration sensor detects that the mixed liquid concentration is lower than the preset lower limit value, the electromagnetic valve of the concentrated liquid supply pipeline is preferentially opened by the control unit, and the concentrated liquid is supplemented into the wiper washing kettle at a preset flow rate until the concentration returns to the target range; In step C2, when the concentration sensor detects that the mixed liquid concentration is higher than the preset upper limit value, the electric valve of the condensed water delivery pipeline is preferentially opened by the control unit, and the condensed water is supplemented into the wiper washing kettle at a preset flow rate until the concentration returns to the target range; In step C3, the control unit dynamically adjusts the supplement flow rate according to the concentration deviation value, and the supplement flow rate increases correspondingly when the deviation value is larger, so as to shorten the adjustment time.

[0062] The beneficial effect of the embodiment is that the real-time monitoring of the concentration sensor and the rapid response of the control unit realize the rapid adjustment of the mixed liquid concentration. The supplement flow rate is dynamically adjusted according to the concentration deviation value, which improves the adjustment efficiency and ensures the stability of the wiper water concentration.

[0063] In one embodiment, The concentrated liquid contains an organic alcohol substance for improving the anti-freezing ability of the wiper water, and the method can also be implemented as the following steps D1-D2: In step D1, the current season information is obtained; In step D2, the target concentration of the wiper water is determined according to the current season information, wherein the target concentration of the wiper water in winter is greater than that in other seasons.

[0064] In one embodiment, a filter structure is provided in the wiper water communication assembly.

[0065] By setting a specific filter structure for the wiper water communication assembly, the quality of the wiper water is further improved. During the process of transporting the condensed water from the condensed water storage assembly to the wiper washing kettle, the filter structure can effectively intercept impurities, dust and small particles that may be contained in the condensed water. In this way, the condensed water entering the wiper washing kettle is more pure, and the wiper water made by mixing and diluting the condensed water with the concentrated liquid has better cleaning effect. During the use of the vehicle, the pure wiper water can more effectively clean the windshield, reduce the scratches caused by impurities, prolong the service life of the windshield, and also provide the driver with a clearer and non-interfering view, greatly improving the safety and comfort of driving.
