Description

Technical Field

[0001] The present invention relates to the technical field of vehicle anti-pinch devices, and particularly to an active anti-pinch system for electric vehicle doors. Background Art

[0002] With the rapid development of the domestic automotive industry, the intelligent levels of traditional fuel vehicles and new energy vehicles are getting higher and higher. Electrically-assisted doors and electric doors are gradually becoming standard or optional features of vehicles, and the "anti-pinch" problem of vehicle doors has increasingly become an important indicator for more and more people to evaluate vehicle safety.

[0003] For the existing problem of pinching hands in electric vehicle doors or electrically-assisted doors, the commonly used anti-pinch solutions are usually passive anti-pinch. This anti-pinch mechanism mainly detects the object being pinched through sensors, such as an item or the user's hand. When the anti-pinch force reaches 80N - 100N, the electric door system will stop closing or reverse a small angle. However, this passive anti-pinch method has certain limitations in practical applications. First, before the anti-pinch force reaches the set value, the object being pinched may have been damaged to a certain extent. Second, for sensitive parts such as fingers, even after the anti-pinch force is triggered, it may cause minor to moderate injuries. In addition, due to the response speed and sensitivity of the anti-pinch system being limited by the detection ability of the sensors and the control algorithm, in some cases, the anti-pinch effect is not ideal, seriously affecting the user experience and safety.

[0004] Therefore, there is an urgent need for an active anti-pinch system for electric vehicle doors to solve the above problems. Summary of the Invention

[0032] As Figures 1 to 4As shown in the figure, this embodiment provides an active anti-pinch system for an electric vehicle door. The active anti-pinch system for the electric vehicle door includes an anti-pinch detection device 1 and a controller 3. The anti-pinch detection device 1 is installed on the vehicle door. When the vehicle door is in a non-closed state, a detection area to be detected is formed between the vehicle door and the body assembly 2. The anti-pinch detection device 1 is used to detect and determine whether there is an object in the detection area to be detected. The controller 3 is used to control the opening and closing of the vehicle door, and the controller 3 is communicatively connected to the anti-pinch detection device 1. With such a setting, during the process of the vehicle door being closed electrically / manually, the anti-pinch detection device 1 detects and determines whether there is an object in the detection area to be detected throughout the process. If there is no abnormality, the door is closed normally; if the anti-pinch detection device 1 detects an object, it will continue to transmit and feedback to the controller 3, and the controller 3 controls the electric vehicle door to stop closing, realizing active anti-pinch, which can improve the overall safety and reliability of the electric vehicle door and enhance the user experience.

[0033] It should be noted that, in order to avoid false triggering, the non-pinching area inside the door frame of the body assembly 2 is pre-calibrated as a non-detection area in advance, which avoids the technical loophole that the electric door cannot be closed when there is someone in the vehicle. And this active anti-pinch system for the electric vehicle door can be widely applied to door systems with electric suction locks such as electric side-opening doors, electric sliding doors, electric swing doors / electric pendulum doors, and electric suction doors.

The door trim assembly 4 is installed inside the door sheet metal assembly 5, and the anti-pinch detection device 1 is installed inside the door trim assembly 4. With such a setting, by placing the anti-pinch detection device 1 inside the door trim assembly 4, it not only does not affect its function, but also there is no risk of signal shielding, and it will not be damaged by foreign objects, thus extending its service life.

[0035] In this embodiment, in order to improve the stability and safety of the structural connection between the vehicle door and the body assembly 2, the active anti-pinch system for the electric vehicle door further includes a first hinge 6 and a second hinge 7. The first hinge 6 and the second hinge 7 are arranged at intervals in the vertical direction.

One side of the electric limiter 8 is mounted on the door sheet metal assembly 5, and the other side of the electric limiter 8 is mounted on the vehicle body assembly 2. The controller 3 is communicatively connected to the electric limiter 8, and the electric limiter 8 is used to control the movement range of the door. With such a setting, the controller 3 can electrically assist the door to be electrically opened or closed around the rotation axes of the first hinge 6 and the second hinge 7 to any position until the fully open or fully closed position is reached. The whole process is smooth, without jamming or abnormal noise, and the door can hover at any position.

[0037] Optionally, in order to be able to achieve the automatic gentle closing of the door and enhance the operation convenience of the user, the active anti-pinch system for the electric vehicle door further includes an electro-suction lock assembly 9.

In actual application, it can be determined whether there is an object in the area to be detected according to the radar distance signal or the detection feedback of the camera. Of course, in other embodiments, the anti-pinch detection device 1 can also be set as any foreign object detection module according to actual needs, and no further limitation is made here.

[0040] Optionally, the door has an opening and closing side along the opening direction away from the vehicle body assembly 2. When the door is in a non-closed state, there is a distance between the opening and closing side and the vehicle body assembly 2, and the area to be detected includes the area between the opening and closing side and the vehicle body assembly 2.
