The holding member 60 is fixedly mounted to the nut bracket 54.

In the present embodiment, the nut 52 may be a ball nut or a "T" nut.

In the present embodiment, the number of the abutting pieces 60 is two, and the two abutting pieces 60 are respectively symmetrically disposed on two opposite sides of the nut bracket 54. Each of the holding members 60 includes a nut pin 62 and a pin bearing 64, the nut pin 62 is fixedly installed on the nut bracket 54 along a radial direction of the nut 52, the nut pin 62 is perpendicular to the lead screw 40, the pin bearing 64 is sleeved outside the nut pin 62, and the pin bearing 64 is fixed on the nut pin 62, and the pin bearing 64 is used for holding a groove wall of the guide groove 72.

It will be appreciated that in some embodiments, the nut bracket may be omitted, the nut being disposed externally of the lead screw, the nut being in threaded engagement with the lead screw. The holding piece is connected with the nut along the radial direction of the nut. Specifically, in one embodiment, referring to fig. 6, the sliding assembly 50 is an integrated nut that is sleeved outside the lead screw 40 and is in threaded engagement with the lead screw 40, and the integrated nut is equivalent to integrating the nut 52 and the nut bracket 54.

When the nut bracket is omitted, the abutting rod can be welded to the nut, or the abutting rod and the nut can be mounted on the nut in an integrated structure.

Referring to fig. 4 and 5, one end of the oscillating member 70 is fixedly connected to the main shaft 80, and the other end thereof is provided with a guide groove 72. In the present embodiment, the oscillating member 70 is an oscillating arm, and the number is two. The two swing arms 70 are located on opposite sides of the slide assembly 50, respectively, and are symmetrically disposed with respect to the slide assembly 50. Each of the buttresses 60 is movably mounted in the guide slot 72 of a corresponding one of the swing arms 70. One end of the swing arm 70 is fixedly sleeved outside the main shaft 80, and the swing arm 70 rotates to drive the main shaft 80 to rotate together.

The guide slots 72 are blind slots, the guide slot 72 of one swing arm 70 faces the guide slot 72 of the other swing arm 70, and each abutting member 60 is movably mounted to the guide slot 72 of the corresponding one swing arm 70.

In the present embodiment, the guide slots 72 are blind slots, and the guide slot 72 of one swing arm 70 faces the guide slot 72 of the other swing arm 70, so as to prevent dust or impurities from falling into the guide slots 72, thereby influencing the sliding of the retainer 60 along the guide slots 72. It will be appreciated that in some other embodiments, the channels 72 may also be through slots.

It will be appreciated that in some other embodiments, one end of the swing arm 70 may be secured to the spindle 80 in other ways, for example, one end of the swing arm 70 is welded to the spindle 80.

The main shaft 80 is a power output shaft of the barrier gate, one end of the main shaft 80 can be fixedly provided with a rod handle 82 (see fig. 5), the barrier gate rod is fixed through the rod handle 82, and the rotation of the main shaft 80 can drive the barrier gate rod to rotate so as to lift or fall.

Referring to fig. 8 to 12, in the present embodiment, the guide slot 72 is a curved shape and is approximately a "U" shaped slot, and during the process that the abutting member 60 moves from one end of the guide slot 72 to the other end, an included angle between the direction a of the abutting member 60 moving along the screw 40 and the direction B of the abutting member 60 moving along the guide slot 72 is first increased and then decreased, so that the abutting member 60 abuts against the swinging member 70 to swing, so as to drive the main shaft 80 to rotate at a gradually increased speed and then rotate at a gradually decreased speed. It will be understood that the rotation speed of the main shaft 80 during the movement of the holding member 60 from one end to the other end of the guide groove 72 is not limited to uniform acceleration or uniform deceleration, but the acceleration may be varied, for example, the rotation speed of the main shaft 80 may be first accelerated slowly, then accelerated quickly, then decelerated quickly, and finally decelerated slowly, and how to specifically accelerate or decelerate the main shaft 80 may be set according to actual conditions, and the rotation speed of the main shaft 80 may be first accelerated and then decelerated during the movement of the holding member 60 from one end to the other end of the guide groove 72.

The direction a of the holding member 60 moving along the screw 40 is always constant, and the direction B of the holding member 60 moving along the guide slot 72 changes according to the different positions of the holding member 60 in the guide slot 72, so that the included angle between the direction a of the holding member 60 moving along the screw 40 and the direction B of the holding member 60 moving along the guide slot 72 changes continuously.

If the included angle between the direction a of the abutting piece 60 moving along the screw 40 and the direction B of the abutting piece 60 moving along the guide groove 72 becomes larger in the process that the abutting piece 60 moves along the guide groove 72, the acting force of the abutting piece 60 on the swinging piece 70 becomes larger in the direction perpendicular to the rotation center line of the screw 40, so that the speed of the abutting piece 60 pushing the swinging piece 70 to swing becomes faster, and the main shaft 80 is driven to rotate at an increased speed; if the included angle between the direction a of the holding member 60 moving along the screw 40 and the direction B of the holding member 60 moving along the guide groove 72 becomes smaller in the process that the holding member 60 moves along the guide groove 72, the acting force of the holding member 60 on the swinging member 70 becomes smaller in the direction perpendicular to the rotation center line of the screw 40, so that the swinging speed of the swinging member 70 pushed by the holding member 60 becomes slower, and the main shaft 80 is driven to rotate at a reduced speed.

The two ends of the U-shaped guide slot 72 are respectively provided with a first slot portion 721 and a second slot portion 723 for realizing the self-locking of the main shaft 80. When the holding member 60 moves to the first slot portion 721 or the second slot portion 723, an included angle between the direction a of the holding member 60 moving along the screw 40 and the direction B of the holding member 60 moving along the guide slot 72 is greater than or equal to zero and less than 10 °.

Specifically, referring to fig. 8, when the holding member 60 moves to the first slot portion 721, an included angle between the direction a of the holding member 60 moving along the screw 40 and the direction B of the holding member 60 moving along the guide slot 72 is greater than or equal to zero and less than 10 °.

Specifically, referring to fig. 12, when the holding member 60 moves to the third groove 723, an included angle between the direction a of the holding member 60 moving along the screw 40 and the direction B of the holding member 60 moving along the guide groove 72 is greater than or equal to zero and less than 10 °.

When the included angle between the direction A and the direction B is equal to zero, the sliding assembly 50 is in a complete self-locking state; when the included angle between the direction a and the direction B is greater than zero and less than 10 °, the sliding assembly 50 is in a relative self-locking state.

The fully self-locking state means that the motor can not make the barrier rod move by applying force to the barrier rod from the outside in the non-electrified state. The relative self-locking state is relative to the complete self-locking state, which means that the motor applies a small acting force to the barrier gate rod from the outside in the non-electrified state and cannot move the barrier gate rod, and a very large acting force needs to be applied to the barrier gate rod from the outside to move the barrier gate rod. The closer the included angle between the direction a of the holding member 60 moving along the screw 40 and the direction B of the holding member 60 moving along the guide groove 72 is to zero, the closer the relative self-locking degree of the sliding assembly 50 is to the full self-locking state.

Referring to fig. 13, when the angle between the direction a of the holding member 60 moving along the screw 40 and the direction B of the holding member 60 moving along the guide slot 72 is zero, if an external force is applied to the bar to lift or drop the bar, the external force is transmitted to the main shaft 80 through the bar and is converted into a rotating force F1 acting on the main shaft 80, the rotating force F1 acts on the swinging member 70 and is converted into a thrust F2 acting on the holding member 60, and the thrust F2 is perpendicular to the direction a. Because there is no thrust acting on the holding member 60 along the direction a, the holding member 60 cannot move along the direction a, and the sliding assembly 50 is in a complete self-locking state.

Referring to fig. 14, when the included angle between the direction a of the holding member 60 moving along the screw 40 and the direction B of the holding member 60 moving along the guide slot 72 is greater than zero and less than 10 °, if an external force is applied to the bar to lift or drop the bar, the external force is transmitted to the main shaft 80 through the bar and converted into a rotating force F1 acting on the main shaft 80, the rotating force F1 acts on the swinging member 70 and converted into a pushing force F2 acting on the holding member 60, and the included angle between the pushing force F2 and the direction a is less than 90 ° and greater than 80 °. Because the component of the pushing force F2 in the direction a is small, the pushing force F2 needs to be very large to push the holding member 60 to move in the direction a, and the sliding assembly 50 is in a relatively self-locking state.

In some embodiments, when the holding member 60 is located in the first slot portion 721 or the second slot portion 723, an angle between the direction a of the movement of the screw 40 of the holding member 60 and the direction B of the movement of the holding member 60 along the guide slot 72 may be 1 °, 4 °, 7 °, 9 °, or 10 °.

In some embodiments, when the holding member 60 is located in the first slot portion 721 or the second slot portion 723, the holding member 60 does not contact the end of the guiding slot 72. If the installation of the barrier rod has deviation, the distance between the abutting piece 60 and the tail end of the guide groove 72 is beneficial to adjusting the deviation barrier rod in place.

In some embodiments, when the first slot portion 721 is in the fully self-locking state or the relatively self-locking state, the bar connected to the main shaft 80 is in the horizontal state, and when the second slot portion 723 is in the fully self-locking state or the relatively self-locking state, the bar connected to the main shaft 80 is in the vertical state.

It will be appreciated that in some embodiments, the symmetrical half of the guiding slot 72 is omitted, and the abutting member 60 abuts the swinging member 70 to swing so as to drive the main shaft 80 to rotate with a gradually decreasing speed or rotate with a gradually increasing speed.

In the barrier driving mechanism 100 of this embodiment, while the supporting member 60 moves along the axial direction of the screw 40, the supporting member 60 moves along the guide slot 72, and under the guidance of the guide slot 72, the supporting member 60 swings against the swinging member 70, so as to drive the main shaft 80 to rotate and gradually reduce the rotation speed of the main shaft 80, so that when the barrier driving mechanism 100 of this embodiment is applied to a barrier, the main shaft 80 drives the barrier rod to gradually slow down the rotation speed of the barrier rod in the process of nearly completely falling or nearly completely rising, thereby preventing the barrier rod from generating violent shaking energy to damage the barrier, and at the same time, not delaying the rising or falling speed of the barrier rod.

Referring to fig. 15 and 16 together, another embodiment of the invention further provides a barrier driving mechanism 300, and the barrier driving mechanism 300 shown in fig. 15 and 16 is substantially the same as the barrier driving mechanism 100 of the previous embodiment, except that the barrier driving mechanism 300 includes a swinging member 370, and one end of the swinging member 370 is provided with a guide groove 372. The guide groove 372 is a curved shape, and is substantially an "S" shaped groove, and the "S" shaped groove is provided with two third groove portions 373 and a fourth groove portion 375 (see fig. 17 and 20) for realizing self-locking of the main shaft 80, respectively. When the holding member 60 moves to the third groove portion 373 or the fourth groove portion 375, an included angle between the direction a of the holding member 60 moving along the screw 40 and the direction B of the holding member 60 moving along the guide groove 372 is greater than or equal to zero and less than 10 °.

Referring to fig. 17 to fig. 20, in the process that the supporting member 60 moves from the third groove portion 373 to the end of the guiding groove 372 closer to the main shaft 80, and then moves from the end closer to the main shaft 80 back to the fourth groove portion 375, an included angle between the direction a of the movement of the supporting member 60 along the lead screw 40 and the direction B of the movement of the supporting member 60 along the guiding groove 372 is increased and then decreased, so that the supporting member 60 swings against the swinging member 370 to drive the main shaft 80 to rotate with gradually increasing speed, and then drive the main shaft 80 to rotate with gradually decreasing speed.
