In general, the working principle of the swing gate provided by this embodiment is as follows: the motor as the power output assembly 32 generates power, the screw 331 is driven to rotate through the coupling 336, the screw 331 drives the slider 3321 to push the sliding support 3322 to carry the abutting piece 34 to make a linear motion along the axial direction of the screw 331, and at the same time, the abutting piece 34 also moves in the guide groove 3101 and presses the guide groove 3101, so that the roller 311 makes a circular rotation, the roller 311 carries the first locking piece 312 to rotate synchronously with the second locking piece 315, and then the sleeve 318 rotates along with the rotation, and as the sleeve 318 is connected with the blocking piece 200, the blocking piece 200 also rotates synchronously, thereby realizing the swing brake function.

It is understood that in some embodiments, the guide groove 3101 may be formed by a plurality of straight grooves, for example, the guide groove 3101 is in a folded line shape, or a plurality of curved grooves, for example, the guide groove 3101 is in a curved shape, wherein the shape of the guide groove 3101 can be designed by one skilled in the art according to business needs.

It is understood that the number of the guide grooves 3101 may be one or more.

In some embodiments, the number of the guide grooves 3101 is even and is uniformly distributed along the circumference of the drum 311, the number of the abutments 34 is equal to the number of the guide grooves 3101, and one abutment 34 is movably mounted on each guide groove 3101, so that the abutments 34 uniformly apply force to the drum 311 in the circumference of the drum 311 to push the drum 311 to rotate stably. In this embodiment, the roller 311 is provided with four guide grooves 3101, the four guide grooves 3101 are uniformly distributed along the circumferential direction of the roller 311, and each guide groove 3101 is movably provided with one abutting member 34.

In some embodiments, the curvatures of the guide slots 3101 at the same height are all equal, so that when the plurality of abutments 34 move in the corresponding guide slots 3101 and press the guide slots 3101, the curvatures of the guide slots at the same height are all equal and the bending directions are the same, which can ensure that the plurality of abutments 34 can effectively press the roller 311 to rotate.

Referring to fig. 8, at a height H1, the curvatures of the guide groove position a1 of the first guide groove 71 and the guide groove position a2 of the second guide groove 72 are equal and the bending directions are the same. At a height H2, the curvature of both the guide groove position B1 of the first guide groove 71 and the guide groove position B2 of the second guide groove 72 are equal and the bending direction is the same.

In the conventional swing gate, generally, the rotation speed of the blocking member is adjusted by adjusting the rotation speed of the motor. However, in this embodiment, the guide groove 3101 is designed to be curved, and the guide groove 3101 is configured to have different curvatures at different guide groove positions, so that the swing gate can not only adjust the rotation speed of the blocking member by adjusting the rotation speed of the motor, but also adjust the rotation speed of the blocking member 200 by a mechanical structure.

Therefore, in some embodiments, during the movement of the abutment 34 along the guide groove 3101, the angle between the direction of the abutment 34 along the lead screw 331 and the direction of the abutment 34 along the guide groove 3101 gradually changes, so that the angle variation of the housing assembly 31 in the horizontal circumferential direction is different, and the housing assembly 31 can rotate in a variable speed circle.

It can be understood that the moving direction of the abutting member 34 along the lead screw 331 is a linear moving direction relative to the moving direction of the lead screw 331 with the lead screw 331 as a reference. The direction of movement of the abutment member 34 along the guide groove 3101 is based on the guide groove 3101, and the direction of movement has different directions at different guide groove positions with respect to the direction of movement of the guide groove 3101.

It is understood that "gradually changing" herein means that the included angle of the two moving directions gradually changes along with the abutment member 34 at different guide groove positions, and also means that: when the guide groove 3101 is divided into several guide groove portions, the angle between the two directions of movement is constant for the abutment 34 in one guide groove portion, but is variable for the abutment 34 in a different guide groove portion, so that "gradually changing" here is to be understood as the angle between the two directions of movement being gradually changing when the abutment 34 moves to a different guide groove portion.

In some embodiments, the angle between the direction of the abutment 34 moving along the screw 331 and the direction of the abutment 34 moving along the guide slot 3101 becomes larger, and the force of the abutment 34 on the inner wall of the guide slot 3101 in the direction perpendicular to the axial direction of the screw 331 becomes larger, so that the abutment 34 presses the shell assembly 31 for accelerated circumferential rotation.

In some embodiments, the angle between the direction of movement of the abutment 34 along the lead screw 331 and the direction of movement of the abutment 34 along the guide slot 3101 becomes smaller, and then in a direction perpendicular to the axial direction of the lead screw 331, the force of the abutment 34 against the inner wall of the guide slot 3101 becomes smaller, so that the abutment 34 presses the shell component 31 for a decelerating circular motion.

With continued reference to fig. 8, the guide slot 3101 includes a first slot portion 3105, a second slot portion 3107 and a third slot portion 3109, the second slot portion 3107 being located between the first slot portion 3105 and the third slot portion 3109. The first groove portion 3105 is near one end of the guide groove 3101, the second groove portion 3107 is at the middle of the guide groove 3101, and the third groove portion 3109 is near the other end of the guide groove 3101. It is understood that the second groove portion 3107 may be located at other suitable positions between the first and third groove portions 3105 and 3109.

When the abutment 34 is located in the first groove portion 3105, the stopper 200 is in the open state, and the stopper 200 does not contact the end of the guide groove 3101. When the abutment 34 is positioned in the second groove portion 3107, the stopper 200 is in the closed state. When the abutment 34 is located at the third groove portion 3109, the barrier 200 is in the open state, and the barrier 200 does not contact the other end of the guide groove 3101. The abutment 34 moves from the first slot portion 3105 to the third slot portion 3109 and the stop 200 rotates 180 degrees.

In this embodiment, when the abutment 34 is located in the first groove portion 3105 or the third groove portion 3109, the abutment 34 does not contact the distal end of the guide groove 3101. If there is a deviation in mounting the stopper 200, the distance between the abutment 34 and the end of the guide groove 3101 is advantageous in adjusting the stopper 200 having the deviation in position. It is understood that in some other embodiments, the first and third slot portions 3105 and 3109 may also be located at the ends of the guide slot 3101.

In the process that the abutting piece 34 moves from the first groove portion 3105 to the second groove portion 3107, the included angle between the moving direction of the abutting piece 34 along the screw rod 331 and the moving direction of the abutting piece 34 along the guide groove 3101 is increased and then decreased, so that the abutting piece 34 presses the shell assembly 31 to perform the acceleration circular rotation and then the deceleration circular rotation, and thus, the shell assembly 31 drives the stopper 200 to gradually decelerate when the stopper 200 approaches the brake opening in place, thereby preventing the stopper 200 from shaking, damaging the components and simultaneously preventing noise from being generated. Similarly, during the process of the abutting piece 34 moving from the second groove portion 3107 to the third groove portion 3109, the included angle between the moving direction of the abutting piece 34 along the lead screw 331 and the moving direction of the abutting piece 34 along the guide groove 3101 becomes larger and smaller, so that the abutting piece 34 presses the shell assembly 31 to perform the acceleration circular rotation and then the deceleration circular rotation, and thus, the shell assembly 31 drives the blocking piece 200 to gradually decelerate when the blocking piece 200 approaches the closing position, so that the blocking piece 200 is prevented from shaking, the component is prevented from being damaged, and the noise is prevented from being generated.

Please refer to fig. 9-14. Herein, a direction in which the abutment 34 linearly moves downward along the screw 331 is a first moving direction 101, and a direction in which the abutment 34 moves along the guide groove 3101 is a second moving direction 102.

In fig. 9, the contact piece 34 moves linearly downward along the screw 331 from the first groove portion 3105, in which the first moving direction 101 is linearly downward, and the angle between the second moving direction 102 and the first moving direction 101 is 0 degrees or more and less than 10 degrees.

In fig. 10, the abutment 34 moves along the guide groove 3101, and at this time, the angle between the first movement direction 101 and the second movement direction 102 becomes larger, and the abutment 34 presses the housing assembly 31, so that the housing assembly 31 starts to accelerate in the horizontal circumferential direction.

In fig. 11, the abutment 34 continues to move along the guide groove 3101, at which time the included angle shown in fig. 11 is larger than the included angle shown in fig. 10, the abutment 34 presses the casing member 31 so that the amount of angular change of the casing member 31 in the horizontal circumferential direction continues to become larger, and thus the casing member 31 continues to accelerate the circular rotation.

In fig. 12, the abutment 34 moves close to the second groove portion 3107, and at this time, the included angle shown in fig. 12 is smaller than the included angle shown in fig. 11, and the included angle between the second moving direction 102 and the first moving direction 101 is 0 degrees or more and less than 10 degrees.

In fig. 13, the abutting piece 34 moves toward the third groove portion 3109, and at this time, the angle shown in fig. 13 is larger than the angle shown in fig. 12, and the abutting piece 34 presses the housing assembly 31, so that the amount of angular change of the housing assembly 31 in the horizontal circumferential direction becomes large, and thus, the housing assembly 31 makes an accelerated circumferential rotation.

In fig. 14, the abutting member 34 moves to the third groove portion 3109, at this time, the included angle shown in fig. 14 is smaller than the included angle shown in fig. 13, the included angle between the second moving direction 102 and the first moving direction 101 is greater than or equal to 0 degree and smaller than 10 degrees, the housing assembly 31 is stationary, and the blocking member 200 is in the open state.

The case that the abutting member 34 moves linearly upward along the screw rod 331 is similar to the case that the abutting member 34 moves linearly downward along the screw rod 331, and is not described again here.

When the included angle between the second moving direction 102 and the first moving direction 101 is equal to 0 degree, the housing assembly 31 is in a complete self-locking state; when the included angle between the second moving direction 102 and the first moving direction 101 is greater than 0 degree and less than 10 degrees, the housing assembly 31 is in a relative self-locking state.

The fully self-locking state means that the motor cannot rotate the blocking member 200 at all by applying a force to the blocking member 200 from the outside in a non-energized state. The relative self-locking state is relative to the complete self-locking state, which means that the motor applies a small force to the blocking member 200 from the outside in the non-energized state and cannot rotate the blocking member 200, and a very large force needs to be applied to the blocking member 200 from the outside to move the blocking member 200. The closer the angle between the second moving direction 102 and the first moving direction 101 is to zero, the closer the relative self-locking degree of the housing assembly 31 is to the full self-locking state.

When the housing assembly 31 is in the fully self-locking state, if an external force is applied to the blocking member 200 to rotate the blocking member 200, the external force is transmitted to the roller 311 through the blocking member 200 and is converted into a rotating force acting on the roller 311, the rotating force acts on the abutting member 34 and is converted into a thrust acting on the abutting member 34, and the thrust acting on the abutting member 34 is perpendicular to the first moving direction 101. Due to the fact that no pushing force acts on the abutting piece 34 in the first moving direction 101, the abutting piece 34 cannot move in the first moving direction 101, the abutting piece 34 abuts against the roller 311, and therefore the roller 311 is in a full self-locking state.

When the housing assembly 31 is in the relative self-locking state, if an external acting force is applied to the blocking piece 200 to rotate the blocking piece 200, the external acting force is transmitted to the roller 311 through the blocking piece 200 and converted into a rotating force acting on the roller 311, the rotating force acts on the abutting piece 34 and converted into a pushing force acting on the abutting piece 34, and an included angle between the pushing force acting on the abutting piece 34 and the first movement direction 101 is smaller than 90 degrees and larger than 80 degrees. Since the component of the pushing force acting on the abutting member 34 in the first moving direction 101 is small, the pushing force needs to be very large to push the abutting member 34 to move in the first moving direction 101, so that the abutting member 34 pushes the roller 311 to rotate, and the roller 311 is in a relatively self-locking state.

In some embodiments, where the abutment 34 is located in any of the first, second, and third slot portions 3105, 3107, 3109, the angle of the second direction of motion 102 from the first direction of motion 101 can be 1 °, 4 °, 7 °, 9 °, or 10 °.

It is understood that in some embodiments, a portion of the guide slot 3101 may be omitted, as long as the stop 200 is rotated 90 degrees as the abutment 34 moves from the first slot portion 3105 to the second slot portion 3107, in particular, when the abutment 34 is in the first slot portion 3105, the stop 200 is in the open state; the abutment 34 moves from the first groove portion 3105 to the second groove portion 3107, the stopper 200 rotates 90 degrees, and the stopper 200 closes; the abutment 34 moves from the second groove portion 3107 back to the first groove portion 3105, the stopper 200 rotates 90 degrees, and the stopper 200 is opened.

Generally, when the swing gate needs to be rotated, the motor is just started to work, in order to protect the motor, the rotating speed of the motor just started is relatively slow, the middle process is relatively fast, and the rotating speed gradually becomes slow before the rotation is finished. The conventional swing gate mainly depends on the control logic of the motor itself to achieve the above purpose, however, in the present embodiment, as shown in the swing gate of fig. 9 to 14, when the abutting member 34 moves from top to bottom or from bottom to top, the abutting member 34 can press the guide slot to drive the blocking member 200 to rotate gradually and sequentially according to the change from slow speed, high speed and slow speed, on one hand, it can change the rotation speed of the blocking member 200 through the mechanical structure, on the other hand, it can protect the motor.

The width of the first groove portion 3105 and the width of the third groove portion 3109 both match the outer diameter of the abutment 34. The width of the guide groove 3101 at other portions than the first and third groove portions 3105 and 3109 is slightly larger than the outer diameter of the abutment 34.

In some embodiments, matching the width of first slot portion 3105 and the width of third slot portion 3109 to the outer diameter of abutment 34 means: the width of the first groove portion 3105 and the width of the third groove portion 3109 are slightly smaller than or equal to the outer diameter of the abutment 34. When the width of the first groove portion 3105 and the width of the third groove portion 3109 are slightly smaller than the outer diameter of the abutment 34, and the abutment 34 moves to the first groove portion 3105 or the third groove portion 3109, the abutment 34 is caught by the first groove portion 3105 or the third groove portion 3109, and a larger force needs to be applied to the abutment 34 to push the abutment 34 to be separated from the first groove portion 3105 or the third groove portion 3109. When the width of the first groove portion 3105 and the width of the third groove portion 3109 are equal to the outer diameter of the abutment 34, when the abutment 34 moves to the first groove portion 3105 or the third groove portion 3109, the abutment 34 contacts the side wall of the guide groove 3101, but the abutment 34 is not caught by the first groove portion 3105 or the third groove portion 310.

In some embodiments, each guide slot 3101 includes opposing first and second sidewalls 3102 and 3103. When the abutment member 34 moves on the screw 331 in the first linear direction, the abutment member 34 presses the first side wall 3102 of the corresponding guide groove 3101, and the adjacent abutment member 34 abuts against the second side wall 3103 of the corresponding guide groove 3101.

When the abutting piece 34 moves on the screw rod 331 in the second linear direction, the abutting piece 34 presses the second side wall 3103 of the corresponding guide groove 3101, and the adjacent abutting piece 34 abuts against the first side wall 3102 of the corresponding guide groove 3101, wherein the first linear direction is opposite to the second linear direction.

Referring to fig. 15 to 17, the abutting member 34 moves linearly downward on the screw 331. First, when the screw 331 drives the slider 3321 to push the sliding support 3322 to linearly move downward in the screw 331 in synchronization with the first abutment 341 and the second abutment 342, the force of the first abutment 341 acting on the first side wall 3102 of the third guide groove 91 is zero, but the second abutment 342 is capable of abutting against the first side wall 3102 of the fourth guide groove 92, so that the second abutment 342 presses the first side wall 3102 of the fourth guide groove 92, and thus the drum 311 rotates clockwise. The zero force of the first abutting member 341 acting on the first side wall 3102 of the third guide groove 91 means that: the first contact member 341 does not contact the first side wall 3102 of the third guide groove 91 or the first contact member 341 does not apply a force to the first side wall 3102 although contacting the first side wall 3102.

For example, when the first and second abutments 341 and 342 move to the positions shown in fig. 18, since each abutment moves downward, as shown in fig. 19, the first abutment 341 is suspended in the third guide slot 91, that is, the force applied by the first abutment 341 to the first side wall 3102 or the second side wall 3103 of the third guide slot 91 is zero. However, as shown in fig. 20, the second abutment 342 abuts the first sidewall 3102 of the fourth guide slot 92.

Referring to fig. 18 to 20, the abutting member 34 moves linearly upward on the screw 331. First, when the screw 331 drives the slider 3321 to push the sliding support 3322 to move linearly upward on the screw 331 in synchronization with the first abutment 341 and the second abutment 342, the force of the second abutment 342 acting on the second side wall 3103 of the fourth guide groove 92 is zero, but the first abutment 341 can abut against the second side wall 3103 of the third guide groove 91, so that the first abutment 341 presses the second side wall 3103 of the third guide groove 91, and the roller 311 rotates in a counterclockwise circle.

For example, when the first and second abutments 341 and 342 move to the position shown in fig. 18, as each abutment moves upward, the first abutment 341 abuts against the second side wall 3103 of the third guide groove 91 as shown in fig. 19. As shown in fig. 20, the second abutment 342 is suspended in the fourth guide slot 92, that is, the force of the second abutment 342 on the first side wall 3102 or the second side wall 3103 of the fourth guide slot 92 is zero.

Thus, compared to a solution with only one guide groove, such a solution requires an increase of the gap between the abutment member and the guide groove to ensure that the abutment member is able to effectively squeeze the guide groove when moving upwards or downwards. However, in this embodiment, when the screw 331 drives the sliding block 3321 to push the sliding support 3322 to carry the abutment member 34 to move linearly upward or downward on the screw 331, one abutment member of two adjacent abutment members abuts against the sidewall in its own guide slot to push the housing assembly 31 to rotate circumferentially, and correspondingly, the other abutment member hangs in its own guide slot or the abutment member abuts against the sidewall of its own guide slot but does not apply force. Because the clearance between the abutting part and the guide groove is reduced, the abrasion resistance between the abutting part and the guide groove can be increased, and the service life of the swing brake is prolonged.

Referring to fig. 21, a swing gate system 900 includes two swing gates 100 as described in the above embodiments, and the two swing gates 100 are arranged oppositely, it can be understood that a person skilled in the art can select any number of swing gates to form a swing gate system according to business requirements, so as to implement corresponding business functions.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; within the idea of the invention, also technical features in the above embodiments or in different embodiments may be combined, steps may be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
