[0036] Example 3:

[0037] like Figure 4 and 13As shown, in combination with the technical solution of Example 2, in this embodiment, the transmission assembly includes a transmission shaft 51, a transmission gear 52, a driven gear 53, and a transmission beam 54. The transmission beams 54 are respectively arranged on both sides of the gate body 1. A door wing rack 56 is provided on one side of the transmission beam 54, and a linkage rack 55 is provided on the lower side of the transmission beam 54. The transmission shaft 51 is rotatably arranged in the middle of the gate body 1, and the transmission gear 52 is arranged at both ends of the transmission shaft 51. The driven gear 53 is rotatably arranged in the gate body 1, and the driven gear 53 is respectively engaged with the linkage rack 55 and the transmission gear 52 for transmission. The fifth drive motor 36 is engaged with one of the linkage racks 55 to control the synchronous operation of the two rotating rods 32 through a single drive motor, so as to facilitate the simultaneous opening and closing of the door wings 31 on both sides of the gate. The lower end of the rotating rod 32 is fixedly connected to a limit tube 61, on which a rotating block 62 is slidably provided, and a limit protrusion is provided along the axial direction of the limit tube 61. A plurality of teeth 63 are provided on the rotating block 62 along the circumferential direction; a rectangular limit block 64 is connected to the lower end face of the rotating block 62, a limit track 6 is provided in the gate body 1, and a telescopic mechanism is provided in the limit tube 61. The output end of the telescopic mechanism is connected to the end face of the rectangular limit block 64, so that the telescopic mechanism drives the rectangular limit block 64 to slide out of the limit track 6 through contraction movement, and the rectangular limit block 64 pushes the rotating block 62 to slide upward on the limit tube 6, so that the teeth 63 engage with the door wing rack 56. The laser sensor 2 is electrically connected to the processing module. When a person passing through the gate fails to recognize the hard gate machine, the laser sensor 2 pre-identifies the behavior of the person breaking through the gate. When the door wing 31 is not fully closed, in order to prevent the door wing 31 from getting stuck to the person passing through the gate and causing accidental injury and damage to the door wing 31, the fourth drive motor 35 drives the screw 33 to rotate to drive the rotating rod 32 to move, so that the door wing 31 moves toward the rear end. In the process of the rotating rod 32 moving toward the rear end, the teeth 63 on the rotating block 62 at its end are acted upon by the door wing rack 56, so that the door wing 31 retreats and closes; when the door wing 31 is fully closed, the telescopic mechanism extends to push the rectangular limit block 64 into the limit track 6 to limit the rotational freedom of the rotating rod 32, so that the person breaking through the gate cannot push open the door wing 31. When the danger is eliminated, the telescopic mechanism retracts, driving the rectangular stopper 64 out of the stopper track 6, releasing the rotational freedom of the rotating rod 32. The rectangular stopper 64 slides upward, driving the teeth 63 on the stopper 62 to engage with the door wing rack 56, allowing the transmission beam 54 to control the rotating rod 32 via the fifth drive motor 36 to drive the door wings 31 to open and close. Specifically, the upper end of the transmission beam 54 is provided with a trapezoidal stopper groove, and the end surface of the lower track groove 42 is provided with a trapezoidal protrusion. The trapezoidal protrusion is located within the trapezoidal stopper groove, allowing the transmission beam 54 to slide linearly on the lower bottom surface of the lower track groove 42. By providing a movable door wing mechanism and a telescopic mechanism, and by providing the transmission beam 54 with the door wing rack 56 and the linkage rack 55, the door wings 31 can be prevented from being accidentally clamped and the door itself can be protected.

[0038] Specifically, there can be two fifth drive motors 36. When there are two fifth drive motors 36, the two door wings 31 on either side of the gate body 1 can be independently controlled without using the transmission shaft 51. Specifically, the telescopic mechanism includes a tube seat 71, a permanent magnet 72, a spring 73, and an iron rod 75 with a wire 74 wound around it. The tube seat 71 is disposed within the limit tube 61, the iron rod 75 is disposed within the tube seat 71, the permanent magnet 72 is slidably disposed within the tube seat 71 via a limit rod 76, the spring 73 is sleeved on the limit rod 76 and connected to the end of the tube seat 71; the end of the limit rod 76 is connected to the rectangular limit block 64 via a connector 77. By providing the telescopic mechanism, the iron rod 75, when energized, becomes magnetic, attracting the permanent magnet 72, thereby driving the limit rod 76 to retract, causing the rectangular limit block 64 to slide upward on the limit tube 61, causing the teeth 63 on the rotating block 62 to engage with the door wing rack 56. Specifically, grooves are provided on both sides of the limiting track 6 so that the connecting member 77 does not interfere with the limiting track 6 when rotating.
