[0023] The present invention will be further described in detail below with reference to embodiments:
[0024] like Figure 1-5 As shown, this utility model provides a door anti-pinch and safety warning device for an autonomous driving shuttle vehicle, including an installation component 1, an opening and closing component 2 and an anti-pinch component 3. The installation component 1 includes a fixing frame 10 and a fixing plate 11. The fixing plate 11 is fixedly installed on the outside of the fixing frame 10, and a sliding groove 12 is provided inside the fixing plate 11.
[0025] like Figure 2 and Figure 3 As shown, the opening and closing assembly 2 is fixedly installed inside the mounting assembly 1. The opening and closing assembly 2 includes a motor 20 and a transmission rod 21. The transmission rod 21 is fixedly installed at one end of the motor 20. A slider 24 is slidably installed inside the sliding groove 12. A connecting rod 23 is rotatably installed on the top of the slider 24. A movable door 13 is rotatably installed at the other end of the connecting rod 23. A rotating rod 22 is fixedly installed on the outside of the transmission rod 21. The other end of the rotating rod 22 is rotatably installed on the back of the movable door 13. The motor 20 drives the transmission rod 21 to rotate, and then the transmission rod 21 drives the rotating rod 22 to rotate, so that the rotating rod 22 drives the movable door 13. At the same time, the movable door 13 causes the slider 24 to move inside the sliding groove 12 through the connecting rod 23, so that the door is closed or opened.
[0026] like Figure 3-5 As shown, the anti-pinch assembly 3 is fixedly installed inside the mounting assembly 1. The anti-pinch assembly 3 includes a pressure sensor 35, a contact plate 33, and an infrared sensor 34. The infrared sensor 34 is fixedly installed inside the contact plate 33. A buzzer 38 is fixedly installed at the bottom of the mounting plate 11. The infrared sensor 34 monitors whether there are foreign objects between the moving doors 13, and the buzzer 38 emits an audible sound to remind passengers to stay away from the moving doors 13. Through the combined action of the infrared sensor 34 and the buzzer 38, passengers are prevented from being pinched by the doors.
[0027] like Figure 3-5 As shown, the interior of the movable door 13 has an installation groove 37. The contact plate 33 is movably installed inside the installation groove 37. The other end of the contact plate 33 is movably connected to a spring 36. The other end of the spring 36 is movably connected to the outside of the pressure sensor 35. The pressure sensor 35 is fixedly installed inside the movable door 13. The pressure sensor 35 and the infrared sensor 34 are both electrically connected to the buzzer 38. The pressure sensor 35 is electrically connected to the motor 20. If a passenger's palm or fingers or other small body parts happen to be outside the detection range of the infrared sensor 34, the two contact plates 33 will be forced to retract, compressing the pressure sensor 35 through the spring 36. The pressure sensor 35 stops the operation of the motor 20, thereby stopping the movable door 13 from closing. Through the combined action of the pressure sensor 35, the contact plate 33 and the motor 20, the passenger is prevented from being pinched by the door. By setting multiple contact plates 33 on the contact side of the two movable doors 13, the monitoring blind spots of the movable door 13 are eliminated.
[0028] like Figure 2 and Figure 3 As shown, a first gear 30 is fixedly installed on the top of the transmission rod 21. A second gear 31 is meshed with the outside of the first gear 30. An angle sensor 32 is fixedly installed inside the second gear 31. The angle sensor 32 is fixedly installed on the top of the fixed plate 11 and is electrically connected to the motor 20. When the motor 20 rotates, it drives the first gear 30 to rotate through the transmission rod 21, and then drives the second gear 31 and the angle sensor 32 to rotate through the first gear 30. The angle sensor 32 monitors the rotation angle of the transmission rod 21, thereby monitoring the opening and closing angle of the movable door 13.
[0029] The working principle of the door anti-pinch and safety warning device of the autonomous driving shuttle bus will be explained in detail below.
[0030] like Figure 1-5As shown, when using the door anti-pinch and safety warning device of this autonomous shuttle vehicle, the motor 20 drives the transmission rod 21 to rotate, which in turn drives the rotating rod 22 to rotate. The rotating rod 22 then drives the movable door 13. Simultaneously, the movable door 13, via the connecting rod 23, causes the slider 24 to move within the sliding groove 12, closing the door. When the door closes, the infrared sensor 34 monitors for any foreign objects between the movable doors 13 and the buzzer 38 sounds an alarm to remind passengers to stay away from the movable door 13. The combined action of the infrared sensor 34 and the buzzer 38... To prevent passengers from being pinched by the doors, if a passenger's hand or fingers or other small body parts happen to be outside the detection range of the infrared sensor 34, the two contact plates 33 will retract under force, compressing the pressure sensor 35 through the spring 36. The pressure sensor 35 will stop the operation of the motor 20, thereby stopping the closing of the movable door 13. Through the combined action of the pressure sensor 35, the contact plates 33 and the motor 20, passengers are prevented from being pinched by the doors. By setting multiple contact plates 33 on the contact sides of the two movable doors 13, the detection blind spots of the movable door 13 are eliminated.
[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
