Description

Technical Field

[0001] The present application belongs to the technical field of vehicle parts, and in particular, relates to a vehicle ultrasonic rainwater removal system and a vehicle. Background Art

[0002] On rainy days, the rain on the windshield will affect the driver's vision, thus increasing driving risks. However, currently, rain is often cleared by controlling the swing frequency of the wipers. On the one hand, the wipers rub against the surface of the windshield during the swinging process, which not only consumes a lot of energy but also has a poor effect in clearing rain in heavy rain or at high speeds. It also produces noise that affects the driver's comfort. In addition, the wiper blades will wear out after long-term use, which will also affect the effect of clearing rain and increase the maintenance cost of the vehicle. Utility Model Content

[0024] The above and / or additional aspects and advantages of the present application will become apparent and easily understood from the description of the embodiments in conjunction with the following drawings, in which:

[0025] Figure 1 It is a structural schematic diagram of the vehicle ultrasonic rainwater removal system provided in an embodiment of the present application.

[0030] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0031] Reference below Figure 1The vehicle ultrasonic rain removal system 100 provided in the embodiment of the present application is described, and the vehicle ultrasonic rain removal system 100 is used to remove rainwater on the windshield 300. The vehicle ultrasonic rain removal system 100 includes a sensor module 110, an ultrasonic module 120 and a control module 130.

[0032] The sensor module 110 is installed on the windshield 300 to obtain rainfall intensity and rain density on the windshield 300 .

[0033] It is understandable that by installing the sensor module 110 on the windshield 300, when rain drops on the windshield 300, the amount of rain on the windshield 300 can be measured in real time, thereby obtaining the rainfall intensity and the density of rain on the windshield 300. The rainfall intensity refers to the total rainfall on the windshield 300 per unit time, and the rain density refers to the distribution of the number of raindrops in a unit volume with their diameters, both of which are direct factors affecting the effect of clearing rain.

[0034] It should be noted that the sensor module 110 includes but is not limited to optical sensors, capacitive sensors, and temperature and humidity sensors. The optical sensor works based on the principle of light refraction. It uses the conical light emitted by the light-emitting diode. When there is rain on the windshield 300, part of the light will deviate, causing the total amount of light received by the optical sensor to change, thereby measuring the rainfall. The capacitive rain sensor measures the rain by using the principle that the dielectric constants of rain and glass are different. The temperature and humidity sensor measures the rain by monitoring parameters such as the temperature and humidity on the surface of the windshield 300 in real time.

[0035] The ultrasonic module 120 is installed outside the windshield 300 to separate rain water from the windshield 300 .

[0036] It can be understood that the ultrasonic module 120 can emit ultrasonic wave beams. Ultrasonic waves are mechanical waves with short wavelengths and high frequencies (usually between 20kHz and 100kHz), thereby causing raindrops on the surface of the windshield 300 to vibrate. Such vibrations will destroy the adhesion between the raindrops and the windshield 300, thereby causing the raindrops to gradually detach from the surface of the windshield 300, thereby achieving the purpose of clearing rainwater without physical contact with the windshield 300, thereby reducing the maintenance cost of the vehicle.

[0037] The control module 130 is respectively connected to the sensor module 110 and the ultrasonic module 120 for adjusting the working parameters of the ultrasonic module 120 according to the rainfall intensity and the rain density. In this embodiment, the control module 130 is located on the windshield 300. Of course, in some embodiments, the control module 130 can also be installed in other parts of the vehicle, which is not specifically limited in this embodiment.

[0038] It is understandable that the control module 130 is connected to the sensor module 110 and the ultrasonic module 120 at the same time, that is, when the control module 130 receives the electrical signal containing the rainfall intensity and rain density sent by the sensor module 110, it processes the electrical signal and sends a control instruction to the ultrasonic module 120, and the control instruction includes the working parameters of the ultrasonic wave, which include but are not limited to the emission frequency and intensity of the ultrasonic wave. That is, the greater the rainfall intensity, the higher the emission frequency of the ultrasonic wave, and the greater the emission intensity of the ultrasonic wave; the greater the rain density, the higher the emission frequency of the ultrasonic wave, and the greater the emission intensity of the ultrasonic wave, so as to adapt to different rainy days and vehicle driving conditions, so as to minimize energy consumption while ensuring the rain removal effect.

[0039] It should be noted that the control module 130 includes a data processing unit and a main control unit. The data processing unit may be a processor, and the processor may be a central processing unit (CPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a network processor (NP) and a digital signal processor (DSP), etc., so as to determine the current working parameters of the ultrasonic module 120 according to the current rainfall intensity and rain density. The main control unit is respectively connected to the sensor module 110, the data processing unit and the ultrasonic module 120 for receiving information reported by the sensor module 110 and the data processing unit, and sending corresponding instructions to the data processing unit and the ultrasonic module 120.

[0040] In this embodiment, the main control unit may be a body control module 130 (Body Control Module, BCM) of the vehicle, which is respectively communicated with the sensor module 110, the data processing unit and the ultrasonic module 120 via a controller area network (CAN) to further improve the integration of the vehicle.

[0041] According to the vehicle ultrasonic rainwater removal system 100 provided in the embodiment of the present application, an ultrasonic module 120 is provided, and the control module 130 adjusts the working parameters of the ultrasonic module 120 according to the rainfall intensity and rainwater density received from the sensor module 110 to adapt to different rainy day conditions and vehicle driving conditions, thereby minimizing energy consumption while ensuring the rainwater removal effect, improving the driver's experience of use and driving safety, and reducing the maintenance cost of the vehicle.

[0042] In some embodiments, Figure 1 As shown, the ultrasonic module 120 includes at least one ultrasonic transmitter, which is located below the windshield 300 and is used to generate an ultrasonic beam.

[0043] It is understandable that, considering that raindrops are affected by gravity and the ultrasonic intensity decreases proportionally with the change of distance, by installing the ultrasonic transmitter below the windshield 300, compared with installing it on both sides or above the windshield 300, it is possible to further reduce energy consumption while ensuring the rainwater removal effect. It should be noted that the shape of the ultrasonic beam emitted by the ultrasonic transmitter and the angle between it and the windshield 300 can be adjusted according to actual needs, and this embodiment does not impose specific restrictions on this.

[0044] For ease of understanding, Figure 1 As shown, the area below the windshield 300 refers to an area on the vehicle frame 200 that is below the lower end of the windshield 300 .

[0045] In addition, considering that the fixed end of the wiper in the related art is often located below the windshield 300, the manufacturing cost can be further reduced by installing the ultrasonic module 120 at the same position as the wiper is installed on the vehicle frame 200.

[0046] In some embodiments, a plurality of ultrasonic transmitters are provided, and the plurality of ultrasonic transmitters are spaced apart along the length direction of the windshield 300, so that the windshield 300 can be partitioned according to the distribution of the plurality of ultrasonic transmitters to further speed up the rainwater removal speed. It should be noted that the number of ultrasonic transmitters and the distance between two adjacent ultrasonic transmitters can be adjusted according to actual needs, and this embodiment does not impose any specific restrictions on this.

[0047] For ease of understanding, the length direction of the windshield 300 refers to the left-right direction of the vehicle.

[0048] In some embodiments, the sensor module 110 includes at least one optical sensor for obtaining rainfall intensity and rain density based on an optical scanning principle. Exemplarily, in order to adapt to a darker driving environment, the optical sensor is an infrared sensor.

[0049] In some embodiments, the windshield 300 includes an outer glass layer and an inner glass layer connected to each other, and the optical sensor is installed between the outer glass layer and the inner glass layer, or the optical sensor is installed on a side of the inner glass layer away from the outer glass layer.

[0050] It is understood that by arranging the optical sensor between the outer glass layer and the inner glass layer, or installing the optical sensor on the side of the inner glass layer away from the outer glass layer, that is, in the interior environment of the vehicle, the influence of the external environment on the optical sensor is reduced, and the service life of the optical sensor is extended. The connection method between the optical sensor and the inner glass layer and the connection method between the optical sensor and the outer glass layer include but are not limited to adhesive bonding.

[0051] In some embodiments, considering the limited detection range of a single optical sensor, such as Figure 1 As shown, a plurality of optical sensors are provided, and the plurality of optical sensors are distributed in an array to obtain the rainfall intensity of each part of the windshield 300 and the rain density on the windshield 300, and further ensure the rain removal efficiency. The number of optical sensors and the distance between two adjacent optical sensors can be adjusted according to actual needs, and this embodiment does not impose any specific restrictions on this.

[0052] In some embodiments, the control module 130 is connected to the ventilation system of the vehicle in communication, and is used to adjust the working parameters of the ultrasonic module 120 according to the air volume of the ventilation system. It can be understood that by connecting the control module 130 to the ventilation system, not only can the temperature inside the vehicle be kept appropriate at all times, but also the airflow introduced by the ventilation system can be used to assist rainwater to separate from the windshield 300, thereby ensuring the effect of rainwater removal while reducing the emission frequency and intensity of ultrasonic waves, further reducing energy consumption.

[0053] In some embodiments, the vehicle ultrasonic rainwater removal system 100 further includes a cleaning module, which is communicatively connected to the control module 130 and is used to spray a cleaning agent onto the windshield 300 .

[0054] It is understandable that, considering that dust and stains adhere to the windshield 300, it is difficult for rainwater to wash them away, thus affecting the driver's field of vision, the cleaning module can spray the cleaning liquid onto the windshield 300, and cooperate with the vibration generated by the ultrasonic wave, so as to achieve the effect of efficient dust removal on the windshield 300.

[0055] The embodiment of the present application further provides a vehicle, which includes a vehicle frame 200, a windshield 300 and the above-mentioned ultrasonic rainwater removal system 100 for a vehicle.

[0056] The material of the frame 200 includes but is not limited to sheet metal, stainless steel, aluminum alloy or titanium alloy.

[0057] The windshield 300 is mounted on the frame 200, and the connection between the windshield 300 and the frame 200 may include but is not limited to bolt connection, rivet connection or snap connection, etc. The windshield 300 is usually made of tempered glass, which has the advantages of high impact resistance and penetration resistance as well as clear visibility.

[0058] It is understandable that at least part of the vehicle ultrasonic rain removal system 100 is installed on the windshield 300. That is, the sensor module 110 is installed on the windshield 300, the ultrasonic module 120 is installed on the frame 200 and close to the connection between the frame 200 and the windshield 300, and the control module 130 can be optionally installed on the windshield 300.

[0059] According to the vehicle provided in the embodiment of the present application, an ultrasonic module 120 is provided in the vehicle ultrasonic rain removal system 100, and the control module 130 adjusts the working parameters of the ultrasonic module 120 according to the rainfall intensity and rain density received from the sensor module 110 to adapt to different rainy days and vehicle driving conditions, thereby minimizing energy consumption while ensuring the rain removal effect, improving the driver's experience of use and driving safety, and reducing the maintenance cost of the vehicle.

[0060] In some embodiments, in order to realize the installation of the ultrasonic module 120 on the vehicle frame 200, the vehicle frame 200 has a first installation structure, and the ultrasonic module 120 of the vehicle ultrasonic rainwater removal system 100 has a second installation structure, and the first installation structure and the second installation structure are detachably connected.

[0061] It is understandable that the first mounting structure includes at least one first mounting hole, the second mounting structure includes at least one second mounting hole, and the fixing member passes through the second mounting structure and is threadedly connected to the first mounting hole to achieve a detachable connection between the ultrasonic module 120 and the frame 200, so as to maintain the ultrasonic module 120. It should be noted that the size, shape and number of the first mounting hole and the corresponding second mounting hole can be designed according to actual needs, and this embodiment does not impose specific restrictions on this. Exemplarily, the fixing member includes a bolt or a screw.
