[0049] Combine the following Figure 1 Embodiment 1 of the present application is described in detail.

[0050] Example 1

[0051] A front windshield cleaning device comprises: a washer liquid driving device 1, a washer liquid spraying device 2 and a control unit; wherein the washer liquid driving device 1 is connected to the washer liquid spraying device 2; the control unit is electrically connected to the washer liquid driving device 1 and the washer liquid spraying device 2 respectively;

[0052] The control unit is used to control the operation of the washing liquid driving device 1 and the washing liquid spraying device 2 according to the vehicle operation status and weather information and the preset infusion rules and spraying rules.

[0053] Specifically, the present application can control the working modes of the washer fluid driving device 1 and the washer fluid injection device 2 according to the vehicle's operating status and weather information, based on preset infusion rules and injection rules, thereby ensuring safe driving behavior and improving the user's driving experience during driving.

[0054] Furthermore, the washing liquid driving device 1 includes: a liquid storage tank 11 for storing washing liquid, and a delivery pump 12 connected to one side of the liquid storage tank 11 and electrically connected to the control unit; the delivery pump 12 is connected to the washing liquid spraying device 2 through a pipeline.

[0055] Specifically, the present application controls the speed and start and stop of the delivery pump 12 through a control unit, thereby adjusting data such as the injection duration, injection cycle, and injection intensity, and constructs washing liquid infusion rules and injection rules based on the injection duration, injection cycle, and injection intensity information, weather information, and vehicle operating status. That is, by setting the priority levels of different weather conditions and vehicle speeds, and associating them with the injection information, a variety of injection modes are pre-set.

[0056] In this embodiment, the washing liquid spraying device 2 includes two spray nozzles 22; each of the spray nozzles 22 has two spraying modes, and are arranged on the trough cover at the rear end of the engine compartment cover through a detachable connection; the two spray nozzles 22 are connected to the delivery pump 12 through a pipeline; wherein, the arrangement spacing between the two spray nozzles 22 is 1 / 3-1 / 2 of the length of the trough cover, preferably 1 / 2.

[0057] It can be understood that the spray nozzle 22 in this embodiment has two spray modes, one is: columnar spray mode; the other is: fan-shaped spray mode; by setting two spray nozzles 22 on the trough cover plate, the spray area of ​​​​the washing liquid can cover the driving sight area of ​​​​the windshield as much as possible, which is convenient for cleaning the windshield surface while improving the user's safe driving behavior.

[0058] In this embodiment, the washing liquid injection device 2 also includes: a two-position three-way solenoid valve 21 electrically connected to the control unit; wherein, a two-position three-way solenoid valve 21 for adjusting the injection mode of the liquid injection nozzle 22 is arranged on the pipeline between each of the liquid injection nozzles 22 and the delivery pump.

[0059] Specifically, the present application can control the spray mode of each liquid spray nozzle 22 individually by controlling the two-position three-way solenoid valve 21, which has a high degree of flexibility.

[0060] Example 2

[0061] like Figure 2As shown, the washing liquid injection device 2 also includes: a two-position three-way solenoid valve 21 electrically connected to the control unit; wherein, two liquid spray nozzles 22 are connected in parallel and connected to a two-position three-way solenoid valve 21 through a pipeline; compared with embodiment 1, the advantage is that, in this embodiment, only one two-position three-way solenoid valve 21 is needed to control the two liquid spray nozzles 22, and the disadvantage is that the flexibility is insufficient. In use, through the two-position three-way solenoid valve 21, only the two liquid spray nozzles 22 can be synchronously controlled to select the same working mode, that is, the two liquid spray nozzles 22 simultaneously spray columnar or fan-shaped washing liquid, and the two liquid spray nozzles 22 cannot be individually controlled separately, and the advantage is that material costs are saved.

[0062] Further, continuing with the above-mentioned embodiment 1, each of the liquid spray nozzles 22 includes: a spray body 220, a first nozzle 221 and a second nozzle 222 arranged on the spray body 220; a first channel 223 connected to the first nozzle 221 and a second channel 224 connected to the second nozzle 222 are arranged inside the spray body 220; wherein, the liquid spray nozzle 22 is connected to the pipeline of the delivery pump 12 through a two-position three-way solenoid valve 21, in the first spraying mode, the first channel 223 is connected to the pipeline of the delivery pump 12, thereby connecting the first nozzle 221 to the delivery pump 12, and in the second spraying mode, the second channel 224 is connected to the pipeline of the delivery pump 12, connecting the second nozzle 222 to the delivery pump 12.

[0063] In this embodiment, the washing liquid sprayed by the first nozzle 221 is in a column shape; the washing liquid sprayed by the second nozzle 222 is in a fan shape.

[0064] It can be understood that the present application, through the two-position three-way solenoid valve 21, independently controls the spraying mode of each spray nozzle 22, has high flexibility and cleaning effect, and improves the user's driving experience while improving safe driving.

[0065] Example 3

[0066] like Figure 3-Figure 5As shown, the liquid spray nozzle 22 includes: a spray body 220, a first spray head 221 and a second spray head 222 arranged on the spray body 220, and a mode adjustment device 227 arranged inside the spray body 220; the spray body 220 is provided with a first channel 223 communicating with the first spray head 221, a second channel 224 communicating with the second spray head 222, an internal chamber 226 for accommodating the mode adjustment device 227, and a third channel 225 communicating with the internal chamber 226; the internal chamber 226 includes It includes a first chamber 2261, a third chamber 2263 and a second chamber 2262 which are connected in sequence; the first chamber 2261 is connected to the first channel 223, the third chamber 2263 is connected to the third channel 225, and the second chamber 2262 is connected to the second channel 224; the third channel 225 is connected to the delivery pump 12; wherein the first channel 223 and the second channel 224 are located on the same side of the internal chamber 226, and the third channel 225 is located on the other side of the internal chamber 226 away from the first channel 223 or the second channel 224.

[0067] like Figure 6-Figure 7 As shown; a nozzle fixing seat 2201 is arranged on the top of the spray body 220; wherein the cross-sectional shape of the nozzle fixing seat 2201 is a fan-shaped structure, and a first nozzle 221 and a second nozzle 222 are arranged in parallel on one side of the nozzle fixing seat 2201; the arrangement direction of the first nozzle 221 and the second nozzle 222 is toward the outer surface of the windshield; the first nozzle 221 and the second nozzle 222 both include a circular connecting portion 228 connected to the nozzle fixing seat 2201 and a spray column 229 connected to the top of the circular connecting portion 228; the circular connecting portion 228 and the nozzle fixing seat 220 1 is an interference fit; the center of the spray column 229 of the first spray head 221 and the second spray head 222 is provided with a cylindrical spray hole 230; wherein, a diverter rod 2202 is provided at the channel outlet position near the circular connecting portion 228 of the second spray head 222 inside the spray head fixing seat 2201; the washing liquid flowing through the spray hole 230 of the second spray head 222 is diverted by the diverter rod 2202; further, a dispersion groove 231 is also provided at the top of the spray column 229 of the second spray head 222; wherein, the outlet of the spray hole 230 of the second spray head 222 is located at the center of the bottom of the dispersion groove 231. The advantage of this design is that it can ensure that the second spray head 222 can spray a wider fan-shaped area and has a better spraying effect.

[0068] The mode adjustment device 227 includes: a push rod 2270 with an I-shaped cross-section, a compression spring 2271 arranged in the first chamber 2261, and an electromagnetic module 2272 arranged in the second chamber 2262 and electrically connected to the control unit; the horizontal part of the push rod 2270 is penetrated in the third chamber 2263, and the two ends of the push rod 2270 extend into the first chamber 2261 and the second chamber 2262 respectively, and the two ends are fixedly provided with a push piston 2273 that can slide within the chamber; the push rod 2270, under the action of the electromagnetic module 2272, can connect the first chamber 2261 with the third chamber 2263 or connect the second chamber 2262 with the third chamber 2263; one end of the compression spring 2271 is fixed to the side wall of the first chamber 2261, so as to ensure the stability of the connection of the compression spring 2271.

[0069] Furthermore, a plug-in port 3 is provided on the side wall of the spray body at the bottom of the electromagnetic module; the electromagnetic module can be electrically connected to the control unit through the plug-in port 3; further, the bottom of the spray body is connected to the sink cover by a snap connection. The plug-in port 3 can play a positioning role, and cooperate with the snap connection of the spray body 220 to have better stability during installation.

[0070] Specifically, the push rod 2270 is made of magnetic material, and a push piston 2273 is fixedly mounted at both ends of the push rod 2270; the push piston 2273 can slide within the first chamber 2261 or the second chamber 2262; wherein, a gap channel for the flow of washing liquid is arranged between the peripheral side of the horizontal part of the push rod 2270 and the third chamber 2263; when in use, the washing liquid flows into the third chamber 2263 through the third pipe, and under the magnetic attraction of the electromagnetic module 2272, the push rod 2270 is driven to move to the right, and the first chamber 2261 and the third chamber 2263 are closed by the push piston 2273 arranged at the left end of the push rod 2270, and the second chamber 2262 and the third chamber 2263 are connected at the same time, and the washing liquid flows into the second chamber 2262 through the third chamber 2263, and flows into the second nozzle 222 through the second channel 224, and is fan-shaped sprayed through the second nozzle 222.

[0071] The difference compared to Example 1 is that the liquid spray nozzle 22 used in this embodiment does not need to control the spray mode of the liquid spray nozzle 22 through a two-position three-way solenoid valve 21. This embodiment controls the spray mode of the liquid spray nozzle 22 by integrating a mode adjustment device 227 inside the liquid spray nozzle 22. The advantage of this design is that it not only improves the control accuracy of the liquid spray nozzle 22, but also increases the response rate of the liquid spray nozzle 22, making the reaction speed of the liquid spray nozzle 22 more sensitive, while saving connecting pipes and reducing the installation space of components, reducing production costs, and significantly improving production efficiency.

[0072] On the other hand, the present application provides a windshield cleaning method, comprising the following steps:

[0073] Step S1: Obtaining the vehicle's operating status and weather information;

[0074] Step S2: According to the running state of the vehicle and weather information, based on preset infusion rules and injection rules, select the injection mode of the washing liquid injection device.

[0075] The running state of the vehicle includes the running speed of the vehicle; the weather information includes at least: rainy day, foggy day, sunny day information, and weather level;

[0076] The step S2 specifically includes:

[0077] Step S21: defining the priority of the spray mode according to the running state of the vehicle and weather information, wherein the priority is ranked in the following order: foggy day > rainy day > running speed;

[0078] Step S22: Based on the priority of the spray mode, according to the preset infusion rule and spray rule, the spray mode of the spray device of the washing liquid is selected.

[0079] Further, step S22 specifically includes:

[0080] Acquire injection information, the injection information at least including: injection duration, injection cycle and injection intensity information;

[0081] Based on the spray mode priority and according to the spray information, the washing liquid infusion rule and the spray rule are constructed to select the spray mode of the washing liquid spray device; wherein the spray mode at least includes the spray method of the spray nozzle and the corresponding spray information.

[0082] For example, when it is detected that the weather at the vehicle's driving position at the current moment has changed from sunny to foggy, and the fog level is heavy fog, the spray duration, spray cycle and spray intensity information corresponding to the heavy fog level are adjusted and selected, and fan-shaped spray is selected at the same time, so as to better disperse and remove fog, dust or stains and ensure the driver's clear vision.

[0083] For example, when the weather is sunny, when the vehicle speed is greater than the preset speed, the columnar spray mode is selected, and when the vehicle speed is less than or equal to the preset speed, the fan-shaped spray mode is selected. For example, the preset speed is 20km / h, and the vehicle speed is 18km / h at this time, and the spray information matching the vehicle speed is selected according to the washing liquid infusion rules and spray rules. The advantage is that when driving on a sunny day, the driver's external vision is relatively clear. When the vehicle speed is high, the columnar spray can prevent the excessive speed from affecting the driver's vision, so as to avoid causing traffic accidents.

[0084] It can be understood that in this embodiment, based on the spray mode priority and according to the spray information, the washing liquid infusion rules and the spray rules are constructed. Through the washing liquid infusion rules and the spray rules, a variety of spray modes are set. Each spray mode pair includes a spray method and corresponding spray information, so as to better disperse and remove dust or stains while ensuring the driver's clear driving vision.

[0086] An acquisition module configured to acquire the running status and weather information of the vehicle;

[0087] The control module is configured to select a spray mode of the washer liquid spray device according to the running state and weather information of the vehicle and based on preset infusion rules and spray rules.

[0088] It is worth noting that although the present system only discloses the acquisition module and the control module, it does not mean that the present device is limited to the above-mentioned basic functional modules; what the present invention wants to express is that, based on the above-mentioned basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with the prior art to form an infinite number of embodiments or technical solutions, that is to say, the present system is open rather than closed, and because the present embodiment only discloses individual basic functional modules, it cannot be considered that the scope of protection of the claims of the present invention is limited to the above-mentioned disclosed basic functional modules.
