Detailed Description
Referring to fig. 1 to 3, the wind vibration canceling system for a vehicle according to the embodiment of the present invention is mainly composed of a rear corner window structure 10, a driving device 30, and a control device 40. Wherein the rear quarter window structure 10 may be mounted at a vehicle rear window position and adjacent to the rear side window 21, rear windshield 22 and C-pillar 23. The rear corner window structure 10 has an opening 13 that can be opened or closed, and the rear corner window structure 10 is configured such that the opening 13 on the rear corner window structure 10 can be controllably opened or closed according to the opening degree of the window opening and the speed of the vehicle driving, so as to eliminate wind vibration, avoid irreversible hearing damage of the user, and improve the comfort level of the user.
The principle of generating the windowed wind detonation of the passenger car is as follows: referring to FIG. 4, when a user is in a high speed window operating condition (e.g., 40-100km/h operating condition), tangential flow at the front edge of the vehicle window is shed due to the lack of a surface to continue to adhere, creating a vortex. The vortex moves further rearward and expands, impacting the interior cavity and the window trailing edge. The cavity in the car is impacted by vortex, and the regular expansion and contraction (pressure fluctuation for short) of 10-20Hz occurs because the pressure cannot be released in time. The vortex striking the trailing edge of the window is reflected by the trailing edge wall (vortex reflection), creating a positive excitation for the front vortex, causing the window leading edge to fall off. Due to the severe impact and extrusion of vortex on the cavity in the vehicle, the cavity generates resonance with corresponding frequency, the resonance frequency is generally distributed at 10-20Hz, and the amplitude is generally more than 120dB (see figure 7). Irreversible hearing impairment, such as tympanic membrane perforation, leakage of ear tissue fluid, tinnitus, otodynia, etc., can result when a human ear is exposed to an environment above 110dB for a prolonged period of time. That is, the booming caused by the high-speed window opening is extremely harmful.
The application starts from the principle of windowing bombing, solves the problem of windowing bombing by utilizing the guiding-out effect, avoids irreversible hearing damage of users, improves the comfort level of the users and improves the brand image of enterprises. Referring to fig. 5, when a user performs an operation of opening the rear side window while the vehicle is running, and the preset vehicle speed and window opening degree for generating the booming are about to be reached, the pressure difference of the cavity in the vehicle reaches the opening threshold value of the opening 13 of the rear angle window structure 10, the opening 13 is opened, the pressure wave is guided out, the window opening booming problem caused by wind vibration is solved, irreversible hearing damage generated by the user is avoided, and the comfort level of the user is improved.
The driving device 30 is electrically connected with the backlight window structure 10, and the driving device 30 can controllably drive the opening or closing of the opening 13 on the backlight window structure 10. The control device 40 is connected to the driving device 30, and the control device 40 is configured to calculate a pressure difference of the cavity in the vehicle according to the opening degree of the window and the running speed of the vehicle, so as to control the driving device 30 to drive the opening 13 on the rear corner window structure 10 to open or close when the pressure difference reaches a threshold value for generating wind vibration. That is, the control device 40 can detect the opening degree of the opening of the vehicle window and the running speed of the vehicle in real time, calculate the pressure change of the cavity in the vehicle, and when the pressure difference of the cavity in the vehicle reaches the pressure difference of wind vibration, control the driving device 30 to drive the rear corner window structure 10 to open the opening 13, so that the pressure wave of the cavity in the vehicle can be led out through the opening 13 of the rear corner window structure 10.
Therefore, according to the wind vibration eliminating system for the vehicle, through the arrangement of the rear corner window structure 10, when the pressure difference of the cavity in the vehicle reaches the threshold value for generating wind vibration, the pressure can be relieved by opening the opening 13 on the rear corner window structure 10, so that the pressure waveguide in the cavity in the vehicle is led out of the vehicle, the window opening bombing problem is effectively solved, and the user experience is improved.

A plurality of pressure relief pieces 12 are spaced apart and built in the backlight window body 11, each pressure relief piece 12 has an opening 13 that can be opened or closed, and the backlight window structure 10 can be configured as a cheek type backlight window structure 10. The plurality of pressure release pieces 12 are respectively connected with a driving device 30, and each pressure release piece 12 is driven by the driving device 30 to open or close the opening 13.
In some embodiments of the present application, referring to fig. 2 and 3, the cross section of the backlight window body 11 may be processed into a substantially right triangle shape, and a plurality of pressure relief pieces 12 may be arranged in a row along one right angle side of the backlight window body 11, and pressure waves of the cavity inside the vehicle may be guided out of the vehicle through the plurality of pressure relief pieces 12.
