Detailed Description
Referring to fig. 1 and 2, the wind vibration self-elimination system according to the embodiment of the present invention is mainly composed of a window sensor 10, a speed sensor 20, a vehicle body controller 30, an air conditioning system 40, and a pressure relief member 50. The window sensor 10 may be configured to detect a window opening, and the window sensor 10 may send a corresponding opening signal according to the detected window opening. The speed sensor 20 may be used to detect vehicle speed, and the speed sensor 20 may issue a corresponding speed signal based on the detected vehicle speed. The vehicle body controller 30 may be connected to the window sensor 10 and the speed sensor 20, the vehicle body controller 30 may receive the opening degree signal and the speed signal, and the vehicle body controller 30 may send a control signal when the opening degree signal and the speed signal reach a threshold value for generating wind vibration. The threshold value for generating wind vibration may be set in advance according to the window opening and the vehicle running speed.
The air conditioning system 40 can be connected with the vehicle body controller 30, and the air conditioning system 40 receives a control signal sent by the vehicle body controller 30 and controls the air conditioning system 40 to adjust to an external circulation mode according to the control signal, so that air flow communicated with the outside of the vehicle is formed in the vehicle, and a closed cavity in the vehicle is damaged. Meanwhile, the pressure relief piece 50 may be installed at a tail portion of the vehicle body, the pressure relief piece 50 may be connected to the vehicle body controller 30, and the pressure relief piece 50 may be configured to open the pressure relief piece 50 upon receiving a control signal transmitted from the vehicle body controller 30, so that pressure fluctuation generated in the vehicle is guided out of the vehicle, thereby achieving a purpose of eliminating wind vibration. The wind vibration self-eliminating system does not change the original mechanism of the vehicle, so that the whole appearance of the vehicle is not permanently changed, and the attractiveness of the vehicle is ensured.
It should be noted that, referring to fig. 3, the principle of generating wind vibration booming during opening windows of a vehicle is: when the user is in a high speed windowing condition (e.g., 40-100 km/h), the tangential flow of the leading edge of the vehicle window drops off due to the lack of a surface to which it continues to adhere, creating vortices. The vortex moves further rearward and expands, impacting the cavity in the vehicle and the trailing edge of the window, creating vortex oscillations. The inner cavity of the vehicle is impacted by vortex, and regular expansion and contraction (short for pressure fluctuation) of 10-20Hz occurs because the pressure cannot be released in time. The vortices impacting the window trailing edge are reflected by the trailing edge wall (vortex reflection), creating a positive excitation to the leading vortex, further exacerbating the vortex shedding by the window leading edge. Just because of the violent impact and extrusion of the vortex on the cavity in the vehicle, the cavity generates resonance with corresponding frequency, the resonance frequency is generally distributed between 10 and 20Hz, and the amplitude is generally more than 120 dB. When the human ear is exposed to an environment of more than 110dB for a long time, irreversible hearing damage, such as perforation of eardrum, leakage of ear tissue fluid, tinnitus, ear pain, etc., may be caused. That is, the booming caused by high-speed windowing has extremely strong hazard.
The window-opening roaring principle is used, referring to fig. 4, based on the existing mature vehicle electronic and electric appliance framework, human-computer interaction is utilized, the window-opening roaring (wind vibration) problem can be well solved, the user is prevented from generating irreversible hearing damage, the comfort level of the user is improved, and the brand image of an enterprise is improved. When a user opens a rear window during the running of the vehicle, that is, when a preset vehicle speed and a preset window opening degree are reached, the air conditioning system 40 controlled by the vehicle body controller 30 on the vehicle is adjusted to an external circulation mode, so that the air conditioning external circulation port 42 performs an external circulation action, and simultaneously, the air conditioning blower 43 automatically supplies air, the pressure relief piece 50 at the tail of the vehicle is also opened, and the internal air flow and the external air flow are communicated. Because the air conditioning system 40 enters the external circulation mode and the pressure relief piece 50 is opened, through air flow is formed between the interior of the automobile and the exterior of the automobile, the original cavity in the automobile is damaged, the cavity in the automobile cannot generate strong pressure fluctuation, the generation of the booming sound is avoided, and the amplitude of the wind vibration is reduced to 103dB from 128 Db.
Therefore, according to the wind vibration self-eliminating system, when the opening degree signal and the speed signal received by the vehicle body controller 30 reach the threshold value for generating wind vibration, the air conditioning system 40 is controlled to be adjusted to the external circulation mode, the pressure release piece 50 is controlled to be opened, air flow communicated with the outside of the vehicle is formed in the vehicle, and meanwhile, the air flow pressure of the cavity in the vehicle is led out through the pressure release piece 50, so that strong pressure fluctuation generated by the cavity in the vehicle is avoided, the problem that users have irreversible hearing damage due to wind vibration is avoided, and the comfort level of the users is improved. The wind vibration self-eliminating system is based on the existing electronic and electric appliance framework of the vehicle, can realize the automatic elimination of wind vibration on the premise of not increasing other structures of the vehicle, and is suitable for large-area popularization and application.

The air conditioner blower 43 is connected to the air conditioner controller 41, and the air conditioner blower 43 can turn on the air conditioner blower 43 according to an air conditioner signal to blow air into the passenger compartment. That is, when the user operates the rear window while the vehicle is running, and when the preset vehicle speed and window opening for generating booming are reached, the air conditioning external circulation port 42 in the air conditioning system 40 controlled by the vehicle body controller 30 on the vehicle is opened to adjust the air conditioning system 40 to the external circulation mode, so that the air conditioning external circulation port 42 performs the external circulation operation, and the air conditioning blower 43 automatically supplies air to the passenger compartment. Meanwhile, the pressure relief member 50 installed at the rear of the vehicle is controlled to be opened by the vehicle body controller 30, so that the inside and outside air flows are communicated. Because the air conditioning system 40 enters the external circulation mode and the pressure relief piece 50 is opened, through air flow is formed between the interior and the exterior of the vehicle, a sound cavity in a passenger compartment is changed, the cavity in the vehicle cannot generate strong pressure fluctuation, the generation of booming sound is avoided, the wind vibration amplitude can be reduced to 103dB from 128Db, and the irreversible hearing damage to a user is avoided.
