[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figure 1-Figure 4 As shown, an automatic door opening device for a passenger car with an anti-pinch function includes an electric door body 1 and an anti-pinch adjustment component 3. The outer wall of the electric door body 1 is fixedly connected with a movable slide rail 2. The anti-pinch adjustment component 3 for anti-pinch adjustment is arranged inside the electric door body 1, and the anti-pinch adjustment component 3 includes a buffer pad 301, a movable bar 302, a support column 303, a fixed block 304 and a first return spring 305. The movable bar 302 is arranged inside the buffer pad 301, and the outer wall of the movable bar 302 is fixedly connected with the support column 303, the outer wall of the support column 303 is slidably connected with the fixed block 304, and the outer wall of the fixed block 304 is connected with the first return spring 305, the end of the support column 303 is connected with a first wiring piece 4, and the end of the first return spring 305 is provided with a first wiring piece 4, the end of the first wiring piece 4 is electrically connected with a second wiring piece 5, and the second wiring piece 5 is arranged inside the electric door body 1;

[0024] The specific operation is as follows: after the electric door body 1 is started, it moves on the outer wall of the vehicle body through the moving slide rail 2. When the buffer pad 301 is subjected to pressure, the buffer pad 301 is made of sponge and can play a buffering role. After the buffer pad 301 is deformed, the internal moving bar 302 is subjected to pressure and moves, driving the support column 303 to slide inside the fixed block 304, and the first return spring 305 is stretched. The support column 303 drives the first wiring piece 4 away from the second wiring piece 5, thereby realizing the disconnection of the power supply, and the circuit can be automatically disconnected when the human body is clamped, which can mechanically prevent clamping and improve safety performance;

[0025] When the buffer pad 301 is restored, the moving bar 302 drives the supporting column 303 to return to its original position, and the first return spring 305 rebounds, driving the first connecting piece 4 to be close to the second connecting piece 5, thereby realizing the reconnection of the power supply;

[0026] The adjusting handle 10 is rotated counterclockwise, and the rotation of the adjusting handle 10 drives the rotating shaft 11 to rotate, and the rotation of the rotating shaft 11 drives the reconnection key 12 to rotate, and the rotation pushes the first terminal piece 4 to move toward the second terminal piece 5, so that the power supply can be reconnected;

[0027] like Figure 1-Figure 4 As shown, an electric door frame bracket 6 is provided on the outer wall of the electric door body 1, and an infrared sensor 7 is provided on the side wall of the electric door body 1, a buffer assembly 8 for buffering is provided below the infrared sensor 7, and the buffer assembly 8 includes an electric push rod 801 and a support rod 802, and the top end of the electric push rod 801 is provided with a support rod 802, and the buffer assembly 8 also includes a buffer adjustment rod 803 and a second return spring 804, and the outer wall of the support rod 802 is rotatably connected to the second return spring 804, and the outer wall of the second return spring 804 is provided with a buffer adjustment rod 803, and the outer wall of the electric door frame bracket 6 is provided with a buffer groove 9, and the buffer groove 9 and the second return spring 804 are adapted, and the outer wall of the electric door frame bracket 6 is provided with an adjustment handle 10, and the end of the adjustment handle 10 is connected to a rotating shaft 11, and the outer wall of the rotating shaft 11 is provided with a reconnection key 12, and the side of the reconnection key 12 is provided with a first wiring piece 4;

[0028] The specific operation is as follows: the infrared sensor 7 can sense the movement of an object passing through the inside of the electric door frame bracket 6. When the infrared sensor 7 senses that someone passes through the electric door frame bracket 6, the bottom end of the electric push rod 801 drives the support rod 802 to move downward, and the buffer adjustment rod 803 and the second return spring 804 move downward accordingly. The bottom of the second return spring 804 fits with the buffer groove 9, and the outer wall of the buffer groove 9 and the outer wall of the second return spring 804 are both frosted, so as to increase the friction. After the second return spring 804 moves downward, the buffer adjustment rod 803 stretches, so as to achieve resistance to the automatic closing of the electric door body 1, slow down the closing speed of the electric door body 1, and prevent the electric door body 1 from closing too fast and being pinched when passing through the electric door frame bracket 6 because there is no time to dodge.

[0029] In summary, if Figure 1-Figure 4As shown, the automatic door opening device for passenger cars with anti-pinch finger is used. First, after the electric door body 1 is started, it moves on the outer wall of the car body through the moving slide rail 2. When the buffer pad 301 is subjected to pressure, the buffer pad 301 can play a buffering role. After the buffer pad 301 is deformed, the internal moving bar 302 is subjected to pressure and moves, driving the support column 303 to slide inside the fixed block 304, and the first return spring 305 is stretched, and the support column 303 drives the first wiring piece 4 away from the second wiring piece 5, so as to disconnect the power supply. When the buffer pad 301 is restored, the moving bar 302 drives the support column 303 to reset, and the first return spring 305 rebounds, driving the first wiring piece 4 to be close to the second wiring piece 5, so as to reconnect the power supply. The adjustment handle 10 is rotated counterclockwise, and the rotation of the rotating shaft 11 drives the reconnection key 12 to rotate, and the rotation pushes the first wiring piece 4 to move in the direction of the second wiring piece 5, which can also reconnect the power supply.

[0030] The infrared sensor 7 can sense the movement of an object passing through the inside of the electric door frame bracket 6. When the infrared sensor 7 senses that someone is passing through the electric door frame bracket 6, the bottom end of the electric push rod 801 drives the support rod 802 to move downward, and the buffer adjustment rod 803 and the second return spring 804 move downward accordingly. The outer wall of the buffer groove 9 and the outer wall of the second return spring 804 are both frosted, which can increase the friction. After the second return spring 804 moves downward, the buffer adjustment rod 803 stretches, thereby realizing resistance to the automatic closing of the electric door body 1 and slowing down the closing speed of the electric door body 1.
