Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

As used herein, directional terms such as "front", "rear", and "rear", etc., are all with reference to the fore-aft direction of the vehicle after the component is mounted to the vehicle. The terms "longitudinal", "longitudinal" and "longitudinal section" are used herein with reference to the front-rear direction of the component after it is mounted to the vehicle, while "lateral", "transverse" and "cross-section" refer to directions perpendicular to the longitudinal direction. The terms "inner" and "outer" are used herein with reference to the vehicle compartment, i.e., the side adjacent to the occupant is the inside and the side adjacent to the outside of the vehicle is the outside. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

At present, a frameless door is easy to damage window glass, the NVH performance of a vehicle is poor, and the quality of generated sound is poor when the door is closed, a door outer plate is knocked, and the window glass is opened and closed, so that the user experience is poor. The applicant carries out excitation simulation test on the vibration condition of the frameless door within a certain frequency range, and the excitation sources generally comprise a lifting motor of the frameless door glass, door closing vibration, tire noise, wind noise and the like. The door outer plate is generally made of 0.65mm-0.8mm steel plate or 0.9-1.1mm aluminum plate, and the like, the bending rigidity is weak, and due to the fact that a metal plate is thin, the vibration excitation amplitude of the central part and the waist line part (approximately positioned below the frameless door window along the height direction of the vehicle body) of the frameless door is large, resonance is easy to occur, and abnormal sound is generated. Therefore, the utility model discloses a door sets up damping component respectively on stringcourse and central point, reduces the vibration range through damping component, promotes the sound quality of whole car.

Regarding the vibration frequency of the vehicle body, there are generally divided into a low frequency region, a middle frequency region and a high frequency region, the low frequency region generally means a frequency less than 300Hz, the middle frequency region generally means a frequency greater than 300Hz and less than 1000Hz, and the high frequency region generally means a frequency greater than 1000 Hz. Of course, the frequency partitioning is only described as an example, and other partitioning manners are obviously possible. The applicant found that when the vibration frequency is in a low frequency region, for example, the vibration frequency has a frequency of 200Hz, it is mainly controlled by the stiffness, i.e., the greater the rigidity of the vehicle body, the vibration frequency can be effectively reduced. When the vibration frequency is in a middle and low frequency resonance region, for example, the vibration frequency is 200Hz to 500Hz, the vibration frequency of this region is usually controlled by a damping structure, that is, the vibration amplitude of the vehicle body is reduced by the damping structure, so as to reduce the sound pressure in the vehicle.

Meanwhile, when the vibration frequency is in a low-frequency region, the vibration frequency is mainly controlled by rigidity, that is, the increase of the rigidity is beneficial to reducing the vibration frequency of the vehicle body, so that the arrangement of the door body anti-collision beam 112 is also beneficial to reducing the noise of the vehicle body. Obviously, the inclination direction of the door body impact beam 112 may be other directions, such as gradually increasing from front to back along the longitudinal direction of the vehicle body.
