DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 , an automatic door with anti-pinch function, comprising an automatic door body 1, a first mounting rod 2 is welded to the top inner wall and the bottom inner wall of the automatic door body 1, a plurality of first rings 3 are welded to the middle part of the first mounting rod 2, a first spring box 4 is slidably inserted in the first ring 3, a first spring 5 is welded to the inner wall of one end of the first spring box 4, a connecting rod 6 is welded to the other end of the first spring 5, an extrusion plate 7 is fixed to the other end of the connecting rod 6 and is located outside the automatic door body 1, a first pressure sensor 8 is fixed to the inner wall of one side of the automatic door body 1 by bolts, the model of the first pressure sensor 8 is JYB-KB-CW-2000, the first pressure sensor 8 is in contact with the first spring box 4, the extrusion plate 7 is moved under the extrusion of a person or a hard object, thereby driving the connecting rod 6 to move, and then the first spring 5 is contracted, thereby buffering the impact force of closing the automatic door body 1, and then the first spring box 4 is moved under the elastic action of the first spring 5, so that the first spring box 4 is squeezed with the first pressure sensor 8, and then the first pressure sensor 8 will The information is transmitted to the central control system of the vehicle, and then the central control system of the vehicle controls the automatic door body 1 to stop closing, so as to avoid pinching people or hard objects. A second mounting rod 9 is welded between the top inner wall and the bottom inner wall of the automatic door body 1, and a second ring 10 is welded to the middle part of the second mounting rod 9. A second spring box 11 is slidably inserted in the second ring 10, and a second spring 12 is welded to the inner wall of one end of the second spring box 11, and a push rod 13 is fixed to the other end of the second spring 12, and the other end of the push rod 13 passes through the automatic door body 1. A second pressure sensor 14 is fixed to the inner wall of one side of the automatic door body 1 by bolts. The model of the second pressure sensor 14 is JYB-KB-CW-2000, and the second spring box 11 contacts the second pressure sensor 14. Under the pressure of the vehicle, the push rod 13 moves, so that the second spring 12 contracts, and then the second spring box 11 moves and presses against the second pressure sensor 14. Then, the second pressure sensor 14 transmits the information to the central control system of the vehicle, and then the central control system of the vehicle controls the automatic door body 1 to stop.

[0023] An outer handle 15 is fixed to the outer wall of one side of the automatic door body 1 by bolts, so as to facilitate opening and closing the automatic door body 1 from the outside of the vehicle.
