Slow-closing device for automobile door and control method thereof

Abstract

The invention discloses a slow-closing device for an automobile door and a control method thereof. When the closing speed of the automobile door is too high, on the premise that the automobile door can still be closed normally, redundant kinetic energy of the automobile door is used for driving a power generator of the slow-closing device to generate power, then electromagnets are driven by the electric energy to work, force for preventing closing is applied to the automobile door at the moment the automobile door is closed, the closing speed of the automobile door is decreased, and vibration and noise generated at the moment the automobile door is closed are reduced. The slow-closing device for the automobile door mainly comprises an execution mechanism, an energy conversion mechanism, a transmission mechanism, a detection mechanism and an electronic control unit, wherein the electronic control unit controls the power generator to work according to the opening angle and the angular speed of the automobile door, the slow-closing device for the automobile door is made to generate corresponding force used for preventing the automobile door from closing according to different angular speeds of the automobile door, and finally the purposes of reducing vibration and noise generated at the moment the automobile door is closed and improving the comfort of passengers in an automobile are realized.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to an automobile door slow closing device and a control method thereof. Background technique [0002] The car door is an important opening and closing part of the car. The door is used as the passage for the driver and passengers to enter and exit the vehicle. Its performance and function directly affect the ergonomics, comfort, sealing and safety of the car. In daily life, on the one hand, due to the influence of factors such as the model of the car, the time of use of the car, and the deformation of the car door, the work required to overcome the resistance during the closing process of the car door is not the same. On the other hand, due to the habits of some drivers and passengers, often In order to ensure that the door can be completely closed, people use too much force when closing the door. This not only causes the door to generate large vibration and noise at the moment ...

Problems solved by technology

In daily life, on the one hand, due to the influence of factors such as the model of the car, the time of use of the car, and the deformation of the car door, the work required to overcome the resistance during the closing process of the car door is not the same. On the other hand, due to the habits of some drivers and passengers, often In order to ensure that the door can be completely closed, people use too much force when closing the door. This not only causes the door to generate large vibration and noise at the moment of closing, which affects the comfort of the occupants in the car, but also causes damage to the door and even the car.
