Detailed Description
Other advantages and capabilities of the present invention will be readily apparent to those skilled in the art from the present disclosure by describing the embodiments of the present invention with specific embodiments thereof in conjunction with the accompanying drawings. The invention is capable of other and different embodiments and its several details are capable of modification in various other respects, all without departing from the spirit and scope of the present invention.
The theoretical principle of the invention is explained first:
firstly, a method of simulation analysis is used for solving a theoretical wind quantity value.
Firstly, establishing a 3D windshield model by using Dasuo CATIA software modeling by means of advanced CAD and CAE workstations;
then, the 3D windshield model data is imported into the flow field analysis software STAR-CCM +, a calculation domain and a calculation boundary are established and finally a simulation result is derived, as shown in fig. 2.
Two sets of important data can be obtained from the conclusions exported from CAE simulations:
one is as follows: the common surface tension sigma of water drops on the glass is about 65 dynes/cm, and the corresponding simulation result shows that at least 60km/h of windward (or 45km/h of side wind) is needed, and the water drops on the glass surface can be blown away;
the second is that: if one could make the surface tension σ of the water drop on the glass about 78 dynes/cm, only 48km/h of head-on wind (or 30km/h of side wind) would be required and the water droplets on the glass would be blown away.
Therefore, the following conclusions can be drawn:
conclusion 1: the water droplet surface tension σ coefficient has a large influence on the result. The greater the surface tension σ (i.e., the more "rounded" the water droplet), the easier it is for the water droplet to be blown away;
conclusion 2: under the same wind speed, the effect of blowing away water drops by side wind is better than that of head-on wind.
It can be seen that increasing the surface tension σ of the water droplets on the glass surface and providing a lateral blow removes the water film or water droplets from the windshield surface.
Secondly, because the surface of the non-stick pan is provided with a layer of polytetrafluoroethylene (commonly known as Teflon) coating, water drops adhered to the non-stick pan are not wet and can keep a round bead rolling, if Teflon material is applied to the surface coating of the surface of the windshield to form hydrophobic glass, the self water removal performance of the glass can be greatly improved naturally, the working principle of the hydrophobic glass is shown in figure 3, the surface tension of the water drops is increased on the surface of the glass, the shape of the water drops is more converged into a round shape, and under the condition that the surface tension of the common glass is reduced, the water drops tend to be 'paralyzed' on the surface of an object due to gravity.
However, even if the glass is added with the Teflon material coating, only the water stain on the surface is changed into a drop shape from a layered shape, and when the vehicle is at rest or at low speed, the water drop still adheres to the surface of the glass to influence the visual field.
After several practical tests, the following conclusions can be drawn:
1. when the speed of the vehicle is lower than 50km/h, water drops on the hydrophobic windshield cannot be blown away by the front wind;
2. when 30km/h of side supply air is provided by the air jet fan, water drops on the hydrophobic windshield can be blown away by the side air;
therefore, according to the conclusion, when the vehicle speed is lower than 50km/h, the side wind can be artificially compensated to blow away water drops so as to ensure that the front view of the driver is unobstructed.
Fig. 4 and 5 are front and side views, respectively, of a windscreen system of a windscreen wiper-less vehicle according to the invention. As shown in fig. 4 and 5, the windscreen wiper system of the windscreen wiper of the invention comprises: the device comprises a hydrophobic windshield 10, a water removal gas circuit 20 and a central control ECU.
The hydrophobic windshield 10 is an automobile glass coated with a transparent hydrophobic material on the surface, and is used for reducing the adsorption force on the glass surface so that water drops on the glass are approximately spherical, specifically, a hydrophobic coating with low surface energy is coated on the automobile front windshield to form the hydrophobic windshield 10, and in the specific embodiment of the invention, the hydrophobic coating is a teflon material or a low surface energy acrylic resin containing fluorine silicon.
The water removing gas circuit 20 is composed of a plurality of air outlets 201 and 203, a pipeline (not shown), a tee joint (not shown), a controllable valve (not shown) and a blower (not shown), and is used for outputting flowing air with different speeds according to instructions of the central control ECU to blow away water drops on the hydrophobic windshield 10, wherein the air outlets are arranged on the a columns on the left side and the right side of the automobile, and the controllable valve, the pipeline, the tee joint and the blower are hidden under an engine cover.
The central control ECU, which may utilize the central control ECU of the automobile itself, is configured to send a corresponding control instruction to the water removing gas circuit 20 according to the current speed information, so as to open or close the water removing gas circuit 20. Specifically, if the current vehicle speed information is greater than or equal to 50km/h, the simulation experiment result shows that water drops on the hydrophobic windshield can be blown away by the head-on wind at the moment, the dewatering gas path 20 is not needed, the hydrophobic windshield 10 supplies wind to the side, and a closing control signal can be generated to a controllable valve of the dewatering gas path at the moment; and when the current vehicle speed information is less than 50km/h, the central control ECU generates a starting control signal to the controllable valve of the water removing gas circuit 20 so as to start the air blower to provide lateral supply air for the hydrophobic windshield 10, and according to simulation experiment results, when the water removing gas circuit only needs to provide the lateral supply air of not less than 30km/h, water drops on the hydrophobic windshield are blown away by the lateral supply air.
The plurality of air outlets 201 and 203 are disposed on the pillar a, specifically, the plurality of air outlets 201 and 203 inclined upward are disposed on the pillar a, preferably, in order to reduce the influence on the strength of the pillar a and ensure the speed of the water-removing air, two air outlets are disposed on the driving side, one to two air outlets are disposed on the passenger side, specifically, as shown in fig. 4 and 5, two air outlets 201 and 202 are disposed on the pillar a in front of the driving seat on the left side, 1 air outlet 203 is disposed on the pillar a in front of the passenger seat, and the windshield 10 is a glass with a transparent hydrophobic coating. Preferably, the inclination angle of the opening is 45 degrees, so that the opening and the windward can form a superposition effect in the same wind direction, and the sector area shown by the dotted line in fig. 4 is a schematic covering view for removing the wind.
Because the column A is a hollow tubular steel structure, the hollow structure of the column A can be used as an air duct of the water removing air path 20, and an air conditioner blower of an automobile is a ready-made air volume source, so that only one air duct connected to an air outlet from a ready-made air conditioning system is needed to form the water removing air path 20, in one embodiment of the invention, a controllable valve and a tee joint are added at the air blower of the automobile to ensure that the water removing air path 20 is added under the condition that the original air path of the automobile is not changed, specifically, one end of the tee joint is connected with the air outlet of the blower, the other end of the tee joint is connected with the original air path of the automobile, the third end of the tee joint is connected with an inlet of the controllable valve, outlets of the controllable valve are respectively connected to outlets of the column A at the left side and the right side of the automobile by pipelines, and the air outlets on the column A and the column A form the water removing air path 20; the control end of the controllable valve is connected with the central control ECU of the automobile to start or close the water removing gas circuit 30 according to the control instruction of the central control ECU.
Preferably, a control switch can be added to the central control of the automobile, and according to needs and actual conditions, the control switch can be a mechanical switch or a touch switch on a touch screen, so that a user can control the functions of the invention.
Therefore, the invention can directly use the waste heat of the engine cooling liquid to supply heat by utilizing the existing automobile air conditioner blower (for supplying air) and the air conditioner compressor (for supplying heat), especially under the working condition of engine warming, so that no extra system energy consumption is generated.
Certainly, in order to avoid the leakage of the cooling and heating air conditioner of the vehicle, in another embodiment of the present invention, an independent water removal air path 20 may be formed by separately adding a blower, a controllable valve, a pipeline, an a-pillar air outlet and an a-pillar air outlet, and the added blower may be disposed under the hood, which is not limited in the present invention.
Therefore, the windscreen wiper system of the windscreen wiper-free automobile has the advantages that the whole mechanical windscreen wiper system is abandoned, the system cost is greatly reduced, and zero interference is realized on the sight of a driver in the rain and snow removing process due to the fact that the windscreen wiper is omitted.
FIG. 6 is a flow chart of steps of a method of implementing a windscreen wiper system in accordance with the present invention. As shown in fig. 6, the method for implementing a windscreen wiper system of a windscreen wiper of a vehicle according to the present invention comprises the following steps:
and step S1, when the external environment is judged to be in a rainy state, current vehicle speed information is obtained.
Since the rain state judgment and the vehicle speed information acquisition are common functions of the existing vehicle, they are not described herein.
Step S2, judging whether the current vehicle speed information is less than the water removal gas path starting threshold, if so, generating a starting control signal to the water removal gas path to start the water removal gas path, and providing side supply air through the water removal gas path; if the threshold value is larger than the starting threshold value of the water removing gas circuit, a closing control signal is generated to the water removing gas circuit.
In the specific embodiment of the invention, the starting threshold of the water removing gas circuit is 50km/h, namely when the current vehicle speed information is more than or equal to 50km/h, the simulation experiment result shows that water drops on the hydrophobic windshield can be blown away by the frontal wind at the moment, and the water removing gas circuit does not need to provide side supply wind at the moment, and a closing control signal is generated to a controllable valve of the water removing gas circuit; and when the current vehicle speed information is less than 50km/h, the central control ECU generates a starting control signal to the controllable valve of the water removing gas circuit so as to start the air blower to provide side supply air for the hydrophobic windshield, and according to simulation experiment results, when the water removing gas circuit only needs to provide 30km/h of side supply air, water drops on the hydrophobic windshield are blown away by the side supply air.
Preferably, after step S2, the method further includes the following steps:
and step S3, acquiring the environment temperature outside the vehicle in real time, and determining to start the air conditioner heating function according to the environment temperature outside the vehicle to blow out hot air to quickly melt the frost on the windshield and blow away raindrops.
Specifically, when the ambient temperature is too low, for example, lower than 0 degree centigrade, and frost is on the windshield, the air conditioning heating function needs to be turned on to blow out hot air to melt the frost on the windshield quickly, so as to blow away raindrops conveniently. In the specific embodiment of the invention, a temperature sensor can be arranged on the vehicle body, then the temperature data acquired by the temperature sensor is transmitted to the central control ECU, and the central control ECU determines whether the acquired temperature is less than 0 ℃ to determine whether the air conditioning function is started by removing the roof.
Preferably, before step S2, the method further includes the following steps:
and monitoring whether a control switch of the water removing gas circuit is turned on, if so, entering the step S2, and if not, directly ending the process.
In the embodiment of the invention, in order to facilitate the use of the user, a control switch for opening or closing the water removing gas circuit by the user can be added to the central control of the automobile, the control switch can be a mechanical switch or a touch switch on a touch screen, before judging whether the speed information is less than the starting threshold value of the water removing gas circuit, the function of the invention started by the user is monitored by monitoring the switch, if so, the step S2 is entered, and if not, the process is directly ended.
Examples
As shown in fig. 7, in the present embodiment, a windscreen wiper system of a windscreen wiper is implemented as follows:
step one, acquiring vehicle speed information and rainfall detection data, and monitoring the state of a control switch;
judging whether the rain is in a rainy state or not, and controlling whether a switch is turned on or not;
if the vehicle is in a rainy state and the control switch is turned on, judging whether the current vehicle speed is greater than or equal to 50km/h, if the current vehicle speed is greater than or equal to 50km/h, otherwise, sending a starting control signal to the controllable valve to start the blower to provide side supply air for the hydrophobic windshield, wherein the provided side supply air speed is not less than 30 km/h;
and step four, acquiring the current environment temperature outside the vehicle by using a temperature sensor, judging whether the current environment temperature is less than 0 ℃, starting the air-conditioning heating function when the current environment temperature is less than 0 ℃, returning to the step one, and otherwise, directly returning to the step one.
