Description

Technical Field

[0001] The present disclosure relates to a washing system for a vehicle and a corresponding vehicle. Background Art

[0002] During long-term use of a vehicle, the windshield, door glass and other parts will be contaminated with dust, dirt and other pollutants, which is not conducive to the appearance of the vehicle. In particular, when the windshield is contaminated with pollutants, it will block the driver's vision, which is not conducive to the safe driving of the vehicle.

[0003] For this purpose, a washing system is usually provided in the vehicle so as to be able to clean various components (such as a windshield). The washing system may include a housing for containing washing liquid and a pumping component for guiding the washing liquid to a corresponding position.

[0004] In winter or cold conditions, for example, if the washing liquid in the washing system of a vehicle is not replaced in time, the washing liquid may solidify and freeze. At this time, if the washing system is started, the washing pump in the washing system will run blocked or idling. The vehicle driver will run the washing system for a long time without knowing that the washing liquid has solidified. At this time, since the washing pump is a short-time working electronic component, it is very easy to cause the washing pump to burn and be damaged, thereby affecting the safety of vehicle driving. In addition, the installation location of the washing pump is often difficult to access, and it is difficult to replace, and the maintenance time and cost are high.

[0005] For this reason, it is necessary to develop a washing system for vehicles that can operate safely and reliably, thereby ensuring the safety of vehicle driving. Utility Model Content

[0006] In view of this, an object of the present disclosure is to provide a washing system for a vehicle and a corresponding vehicle, which can be operated safely and reliably, thereby ensuring the safety of vehicle driving.

[0007] Therefore, according to the first aspect, the present disclosure provides a washing system for a vehicle, wherein the washing system includes: a washing liquid tank for storing washing liquid, a washing pump for pumping washing liquid from the washing liquid tank, a washing nozzle for outputting washing liquid, a washing pipeline connected between the washing pump and the washing nozzle for conveying washing liquid, and a washing controller connected to the washing pump signal to control the washing pump, characterized in that the washing system also includes a Hall flow sensor for detecting the presence of a washing liquid flow in the washing pipeline, and the Hall flow sensor is arranged in the washing pipeline and is connected to the washing controller signal.

[0008] Therefore, by providing a Hall flow sensor in the washing system according to the present disclosure, it is possible to detect whether there is a washing liquid flow in the washing pipeline of the washing system, so as to determine whether the washing pump is operating normally. Thus, when the washing liquid in the washing liquid tank or the washing pipeline freezes, the washing pump will not operate in a blocked or no-load state. Therefore, the washing system according to the present disclosure can operate safely and reliably, thereby ensuring the safety of vehicle driving.

[0009] In some embodiments, the washing system further comprises a control switch that can be manually operated to start and stop the washing system, and the control switch is connected to the washing controller, thereby making it easier for the vehicle driver to control the washing system.

[0010] In some embodiments, the control switch is integrated into a steering wheel combination switch for the vehicle. Thus, the control switch can be realized simply and at low cost.

[0011] In some embodiments, the Hall flow sensor is arranged in the washing pipeline close to the washing pump, thereby facilitating detection of whether there is washing liquid flow in the washing pipeline at the outlet end of the washing pump, thereby more quickly determining whether the washing system is in a normal state.

[0012] In some embodiments, the washing controller is integrated in a control system for the vehicle. Thus, the washing controller can be realized simply and at low cost.

[0013] In some embodiments, the washer fluid tank is disposed inside an engine compartment of the vehicle, thereby facilitating access to the washer fluid tank.

[0014] In some embodiments, the washing pump is arranged on the washing liquid tank, thereby making the structure of the washing system simpler.

[0015] According to a second aspect, the present disclosure provides a vehicle, characterized in that the vehicle has the washing system according to the present disclosure as described above.

[0016] The vehicle according to the second aspect of the present disclosure also correspondingly brings the same advantages as the washing system according to the first aspect of the present disclosure, which will not be described in detail here.

[0017] It can be seen that the washing system according to the present disclosure uses the Hall flow sensor and the logic control system to detect the washing pump to prevent the washing pump from being burned. Therefore, when the washing liquid in the washing liquid tank or the washing pipeline freezes, even if the washing system is started, the washing pump will not run in a blocked or no-load state, and will not be damaged. Therefore, the washing system according to the present disclosure can operate safely and reliably, thereby ensuring safe driving of the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As mentioned at the beginning of this article, in order to ensure a clear field of vision for the vehicle driver, a washing system is usually provided in the vehicle. The existing vehicle washing system may include a washing liquid tank, a washing pump, a control switch, a washing pipeline and a washing nozzle. It can meet the washing performance requirements of the vehicle under non-special circumstances. However, in the case of freezing of the washing liquid, the washing pump is very easy to be damaged due to the lack of detection and control functions, so that the washing system cannot operate safely and reliably.

[0025] Therefore, the washing system for a vehicle according to the present disclosure can prevent the ablation of the washing pump through detection, thereby ensuring the safe and reliable operation of the washing system. Moreover, the washing system according to the present disclosure has a simple structure, a reasonable design, and is easy to install.

[0026] Refer to the following Figure 1 to Figure 2 A washing system 100 for a vehicle according to an embodiment of the present disclosure is described.

[0027] First refer to Figure 1 According to an embodiment of the present disclosure, a washing system 100 may include a washing liquid tank 10 , a washing pump 20 , a washing nozzle 30 , a washing pipeline 40 , a washing controller 50 , and a Hall flow sensor 60 .

[0028] The washer liquid tank 10 may be configured to store washer liquid. Advantageously, the washer liquid tank 10 may be disposed inside an engine compartment of a vehicle.

[0029] The washer pump 20 may be configured to draw washer liquid from the washer liquid tank 10 . The washer pump 20 may be disposed downstream of the washer liquid tank 10 and may pump washer liquid in the washer liquid tank 10 into the washer line 40 .

[0030] The washer nozzle 30 can output, in particular spray, washer fluid onto components of the vehicle, such as a windshield. The washer nozzle 30 may be located at one end of a washer line 40.

[0031] The washer line 40 may be connected between the washer pump 20 and the washer nozzle 30 , and may be configured to convey washer liquid.

[0032] The wash controller 50 may be signal-connected to the wash pump 20 so as to control the wash pump 20 , for example, to start or stop the wash pump 20 .

[0033] The Hall flow sensor 60 may be disposed in the washing pipeline 40 and may be configured to detect whether the washing liquid flows in the washing pipeline 40. The Hall flow sensor 60 may be signal-connected to the washing controller 50 so as to provide feedback to the washing controller 50.

[0034] Therefore, after the washing system 100 is started, when washing liquid flows through the washing pipeline 40, the Hall flow sensor 60 will give a liquid flow signal to the washing controller 50; when no washing liquid flows through the washing pipeline 40, the Hall flow sensor 60 will give a liquid no flow signal to the washing controller 50. The washing controller 50 can control whether the washing pump 20 continues to operate or shuts down according to the signal received from the Hall flow sensor 60.

[0035] Therefore, the washing system 100 according to the present disclosure can detect whether there is washing liquid flowing in the washing pipeline 40 through the Hall flow sensor 60, and then determine whether the washing system state is normal. Therefore, when the washing liquid in the washing liquid tank or the washing pipeline freezes and freezes in winter or cold working conditions, the washing pump will not operate in a blocked or no-load state. Therefore, the washing system 100 according to the present disclosure can operate safely and reliably, thereby ensuring the safety of vehicle driving.

[0036] According to some embodiments of the present disclosure, the washing system 100 may further include a control switch 70 that can be manually manipulated to activate and deactivate the washing system 100. The control switch 70 may be connected to the washing controller 50 to facilitate the vehicle driver to control the washing system 100.

[0037] In a preferred embodiment, the control switch 70 can be integrated into a steering wheel combination switch for a vehicle. Thus, the control switch 70 can be realized simply and at low cost.

[0038] According to some embodiments of the present disclosure, the Hall flow sensor 60 may be disposed in the washing pipeline 40 close to the washing pump 20. Thus, the Hall flow sensor 60 may facilitate detection of whether there is a washing liquid flow in the washing pipeline 40 at the outlet end of the washing pump 20, thereby more quickly determining whether the washing system state is normal.

[0039] According to some embodiments of the present disclosure, the washing controller 50 may be integrated into a control system for a vehicle, thereby enabling the washing controller 50 to be realized simply and at low cost.

[0040] According to some embodiments of the present disclosure, the washing pump 20 may be disposed on the washing liquid tank 10. Thus, the structure of the washing system 100 according to the present disclosure may be simpler.

[0041] Refer to the following Figure 2 The operation manner of the washing system 100 according to the embodiment of the present disclosure is described.

[0042] In step S1, it is determined whether the control switch 70 of the washing system 100 is closed.

[0043] If the control switch 70 is closed, the washing controller 50 controls the washing pump 20 to turn on in step S2 so that the washing pump 20 works.

[0044] In step S3, it is determined whether the Hall flow sensor 60 detects the flow of washing liquid in the washing pipeline 40. If the flow of washing liquid is detected, the process returns to step S2 so that the washing pump 20 continues to work. If the flow of washing liquid is not detected, the washing pump 20 is stopped. In this case, it is possible that if the Hall flow sensor 60 detects the flow of washing liquid, a digital signal "1" is fed back to the washing controller 50, which represents that the washing system is working normally; if the Hall flow sensor 60 detects that there is no flow of washing liquid, a digital signal "0" is fed back to the washing controller 50, which represents that the washing system is faulty. Therefore, the washing controller 50 can perform logical judgment based on the signal fed back by the Hall flow sensor 60, and output a control signal to control the washing pump 20 to work or stop.

[0045] In summary, the technical solution adopted by the present invention can use the Hall flow sensor to detect the washing system of the vehicle, thereby preventing the washing pump from being burned. The Hall flow sensor can be installed in series on the washing pipeline, and its installation position can be close to the washing pump. After the washing system is started, when washing liquid flows through the Hall flow sensor, the Hall flow sensor will give a signal that there is liquid flow; when no liquid flows, the Hall flow sensor will give a signal that there is no liquid flow; then, the washing controller can control the washing pump to continue to run or shut down according to the signal received from the Hall flow sensor. Therefore, for example, in winter or cold working conditions, when the washing liquid in the washing liquid tank or the washing pipeline solidifies and freezes, if the washing system is started, the washing pump will not run in a blocked or no-load state, so that the washing pump will not be damaged. Therefore, the washing system according to the present disclosure can operate safely and reliably, thereby ensuring safe driving of the vehicle.

[0046] It should be understood that the term "vehicle" or "vehicular" or other similar terms used herein generally include motor vehicles, such as passenger vehicles including sport utility vehicles (SUVs), buses, trucks, various commercial vehicles, ships including various boats, vessels, aircraft, etc., and include hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen-powered vehicles and other alternative fuel vehicles (e.g., fuels derived from sources other than petroleum).
