The connecting rod 1 32 is rotated on the housing 1 through the rotating shaft 31, so that the connecting rod 1 32 rotates counterclockwise synchronously with the gate arm 4. The rotation of the connecting rod 1 32 drives the fixing plate 37 rotating at the bottom end to rotate through the connecting rod 2 33. During the rotation, the gate arm 4 and the connecting rod 1 32 continue to maintain a parallelogram to ensure the stability during folding and opening. The fixing plate 37 rotates and drives the gate arm 2 5 connected to its right end to rotate around the fixing plate 37 to the left. The pin shaft at the end rotates as the center, and the gate arm 2 5 rotates through the meshing rotation of the gear 1 35 and the gear 2 36 during the rotation process, thereby driving the gate arm 2 5 and the gate arm 1 4 to rotate in the opposite direction, so that the gate arm 1 4 and the gate arm 2 5 are gradually folded, so that synchronization and coordination can be achieved, thereby achieving the folding opening and closing effect of the entire gate, which can improve the flexibility and applicability of the gate-type access control opening and closing structure, and adapt to different occasions and needs. A supporting mechanism 6 is provided inside the right end of the gate arm 2 5, and the supporting mechanism 6 includes a rotating shaft 61, a supporting rod 62, a sliding hole 64, a spring 65, a sliding column 66, an inclined block 67, a shock absorber 68 and a placement groove 69. The placement groove 69 is provided on the lower surface of the gate arm 2 5, and a rotating shaft is rotatably connected between the front and rear inner walls of the right end of the placement groove 69. Axle 61, a support rod 62 is fixedly sleeved in the middle of the rotating shaft 61, a shock absorber 68 is provided at the left end of the support rod 62, a sliding hole 64 is opened on the left inner wall of the placement groove 69, a sliding column 66 is slidably connected to the inner wall of the sliding hole 64, and a bevel block 67 is fixedly connected to the right end of the sliding column 66, the bevel of the bevel block 67 is matched with the left end of the shock absorber 68 for installation, a spring 65 is fixedly connected between the left side surface of the bevel block 67 and the left inner wall of the placement groove 69, and the spring 65 is sleeved on the outer surface of the sliding column 66, the supporting mechanism 6 also includes a motor 1 63, the motor 1 63 is installed on the rear side surface of the right end of the brake arm 2 5 by bolts, the front end of the output shaft of the motor 1 63 is fixedly connected to the rear end of the rotating shaft 61, and the input end of the motor 1 63 is electrically connected to the output end of the single-chip computer 10,At the same time, when the single chip computer 10 regulates the operation of the motor 2 11, the motor 1 63 is also regulated to operate. The output shaft of the motor 1 63 drives the rotating shaft 61 to rotate clockwise. The rotation of the rotating shaft 61 causes the support rod 62 to rotate clockwise by a certain angle. During the folding process of the brake arm 1 4 and the brake arm 2 5, the support rod 62 continues to rotate until it is aligned with the brake arm 2 5. However, during the rotation of the support rod 62, the shock absorber 68 contacts the inclined surface of the inclined block 67, causing an extrusion force. This extrusion force pushes the inclined block 67 to move leftward. The leftward movement of the inclined block 67 further pushes the slide column 66 to slide into the slide hole 64, and compresses the spring 65 in the process. The support rod 62 continues to rotate until the shock absorber 68 at its end enters the placement groove 69, maintains a horizontal position with the brake arm 2 5, and cancels the extrusion of the inclined block 67. Once the extrusion force is cancelled, the compressed spring 65 rebounds, causing the inclined block 67 and the slide column 66 to rebound and reset, thereby supporting the support rod 62. The support rod 62 and the shock absorber 68, when a pedestrian or a vehicle passes by, and the infrared sensor 2 does not detect that there is a pedestrian or a vehicle passing by, it transmits a signal to the single chip computer 10. After the single chip computer 10 makes a judgment, it adjusts the operation of the motor 2 11, and adjusts the operation of the motor 1 63 during the deployment of the brake arm 1 4 and the brake arm 2 5. The output shaft of the motor 1 63 drives the rotating shaft 61 to rotate in the opposite direction, and the rotating shaft 61 rotates in the opposite direction to drive the support rod 62 to rotate in the opposite direction. When the support rod 62 rotates, it contacts the inclined surface of the inclined block 67 through the shock absorber 68, causing an extrusion force, so that the inclined block 67 drives the slide column 66 to slide into the slide hole 64, and compresses the spring 65 at the same time, and then the motor 1 63 continues to rotate and drives the support rod 62 to rotate until it is perpendicular to the ground, and the bottom end of the shock absorber 68 contacts the ground, so that the damage of the brake arm 1 4 during opening and closing can be reduced through the shock absorber 68, the service life of the system can be extended, and the maintenance and replacement costs can be reduced.

[0027] The working principle of the opening and closing structure of a barrier-type access control provided by the utility model is as follows: first, an external single-chip microcomputer is used to supply power to the single-chip microcomputer 10 through a battery 9, so that the single-chip microcomputer 10 starts to work. After the single-chip microcomputer 10 starts to work, it controls the operation of the infrared sensor 2 according to the preset program and logic. When the infrared sensor 2 detects that a pedestrian or a vehicle passes by, it transmits a signal to the single-chip microcomputer 10. After the single-chip microcomputer 10 makes a judgment, it adjusts the operation of the motor 2 11. The output shaft of the motor 2 11 drives the worm 12 to rotate. The worm 12 is meshed and connected with the worm wheel 8, so that the worm wheel 8 rotates and drives the rotating shaft 7 fixed thereto to rotate counterclockwise. The counterclockwise rotation of the rotating shaft 7 drives the gate arm 4 to start rotating. The rotation of the gate arm 4 drives the connecting rod 32 , the connecting rod 1 32 is rotated on the housing 1 through the rotating shaft 31, so that the connecting rod 1 32 rotates counterclockwise synchronously with the gate arm 1 4, and the rotation of the connecting rod 1 32 drives the fixing plate 37 rotating at the bottom to rotate through the connecting rod 2 33. During the rotation, the gate arm 1 4 and the connecting rod 1 32 continue to maintain a parallelogram, so as to ensure the stability during folding and opening and closing. The rotation of the fixing plate 37 drives the gate arm 2 5 connected to its right end to rotate around the pin shaft at the left end of the fixing plate 37 as the center. However, during the rotation process, the gate arm 2 5 rotates through the meshing of the gear 1 35 and the gear 2 36, thereby driving the gate arm 2 5 and the gate arm 1 4 to rotate in the opposite direction, so that the gate arm 1 4 and the gate arm 2 5 are gradually folded, so that synchronization and coordination can be achieved, thereby realizing the folding of the entire gate. The overlapping opening and closing effect can improve the flexibility and applicability of the gate-type access control opening and closing structure, and adapt to different occasions and needs. At the same time, when the single-chip microcomputer 10 regulates the operation of the motor 2 11, it also regulates the operation of the motor 1 63. The output shaft of the motor 1 63 drives the rotating shaft 61 to rotate clockwise. The rotation of the rotating shaft 61 causes the support rod 62 to rotate clockwise by a certain angle. During the folding process of the gate arm 1 4 and the gate arm 2 5, the support rod 62 continues to rotate until it is aligned with the gate arm 2 5. However, during the rotation of the support rod 62, the shock absorber 68 contacts the inclined surface of the inclined block 67, causing an extrusion force. This extrusion force pushes the inclined block 67 to move to the left. The left movement of the inclined block 67 further pushes the sliding column 66 to slide into the sliding hole 64, and compresses the elasticity in the process. Spring 65, support rod 62 continues to rotate until the shock absorber 68 at its end enters the placement groove 69, maintains a horizontal position with brake arm 2 5, and cancels the squeezing of inclined block 67. Once the squeezing force is cancelled, the compressed spring 65 rebounds, causing inclined block 67 and slide column 66 to rebound and reset, thereby supporting support rod 62 and shock absorber 68. When pedestrians or vehicles pass by, infrared sensor 2 does not detect pedestrians or vehicles passing by, it transmits a signal to single-chip microcomputer 10. After making a judgment, single-chip microcomputer 10 adjusts motor 2 11 to operate, and adjusts motor 1 63 to operate during the deployment of brake arm 1 4 and brake arm 2 5. The output shaft of motor 1 63 drives the rotating shaft 61 to rotate in the opposite direction, and the rotating shaft 61 rotates in the opposite direction to drive support rod 62 to rotate in the opposite direction.When the support rod 62 rotates, the shock absorber 68 contacts the inclined surface of the inclined block 67, causing an extrusion force, so that the inclined block 67 drives the slide column 66 to slide into the slide hole 64, and compresses the spring 65 at the same time. Then the motor 63 continues to rotate and drives the support rod 62 to rotate until it is perpendicular to the ground, and the bottom end of the shock absorber 68 contacts the ground. Therefore, the shock absorber 68 can reduce the damage of the brake arm 4 during opening and closing, extend the service life of the system, and reduce the maintenance and replacement costs.

[0028] It is worth noting that the specific model of the single chip microcomputer 10 disclosed in the above embodiment is S7-200, the infrared sensor 2 can be selected from CPK-TR40MR3, the motor 1 63 can be selected from BMR-50, the battery 9 can be selected from 6-GFM-100, and the motor 11 is recommended to be D180M-0160030B-E. The single chip microcomputer 10 controls the infrared sensor 2, the battery 9, the motor 1 63 and the motor 11 using methods commonly used in the prior art.
