Referring to fig. 1, an embodiment of a gate includes a gate case 200 and a swing arm assembly, wherein a receiving slot 201 is formed on one side of the gate case 200, and the swing arm assembly is disposed in the receiving slot 201. When the gate is actually used, for a group of two simultaneous use, the accommodating grooves 201 of the two gates are oppositely arranged, and the opening and closing of the gate are realized by taking in or extending out of the accommodating grooves 201 through the swing arms 100 in the swing arm assemblies of the group of gates.

Referring to fig. 1 and 2, the swing arm assembly includes a swing arm 100, a linear driving mechanism, and a rotation engagement mechanism. The swing arm 100 is a planar extension having a connecting end and a free end. The linear driving mechanism is slidably connected to the connection end of the swing arm 100, and drives the connection end of the swing arm 100 to slide on the gate case 200 along a sliding direction. The rotation matching mechanism is slidably connected with the swing arm 100, and is used for allowing the free end of the swing arm 100 to rotate around a rotation direction when the swing arm 100 slides along the sliding direction, wherein the rotation direction and the sliding direction are mutually perpendicular.

According to the utility model, the original position fixing of the connecting end of the swing arm 100 is improved to be capable of doing linear motion along a sliding direction, and when the connecting end of the swing arm 100 is in linear motion, the rotating matching mechanism is adopted to match with the swing arm 100, so that when the connecting end of the swing arm 100 is doing linear motion, the connecting end of the swing arm 100 can also rotate, thereby driving the whole swing arm 100 to swing, forward and reverse swinging of the swing arm 100 can be realized through changing the positive and negative directions of the connecting end of the swing arm 100 doing linear motion, and the swing arm 100 is retracted into or extended out of the accommodating groove 201 of the gate machine case 200, thereby realizing door opening and door closing of a gate.

Because the connection end of the swing arm 100 can make a linear motion in the accommodating groove 201 of the gate chassis 200 and enable the swing arm 100 to be retracted into or extend out of the accommodating groove 201, the swing arm 100 can maximally approach the entire length of the accommodating groove 201, and the length of the swing arm 100 can be increased from half of the original accommodating groove 201 to approach the entire length of the accommodating groove 201 on the premise of not changing the size of the original gate chassis 200, so as to meet the requirement of a gate wide channel.

Specifically, the linear driving mechanism includes a first linear slide rail 321 and a driving member, where the driving member is used to drive the connection end of the swing arm 100 to slide along the first linear slide rail 321, so that, for the convenience of sliding the connection end of the swing arm 100 on the first linear slide rail 321 and rotating the swing arm 100, the swing arm 100 is rotationally connected with a first linear slide block 322, and the first linear slide block 322 is slidingly connected on the first linear slide rail 321, so that the connection end of the swing arm 100 can slide along with the first linear slide block 322.

Therefore, the motor 311 can drive the screw shaft of the ball screw 312 to rotate, so as to drive the first linear slider 322 fixed to the screw nut of the ball screw 312 to perform linear motion on the first linear slide rail 321 (the length direction of the first linear slide rail 321 is the sliding direction of the connecting end of the swing arm 100).

Referring to fig. 2 and 4, the swing arm 100 is preferably in a rectangular planar structure having a certain length and width, the swing arm 100 includes a door shaft 120 and a swing arm body 110, the door shaft 120 is rotatably connected to a first linear slider 322, and the swing arm body 110 is fixed to a circumferential surface of the door shaft 120, so that the swing arm 100 can rotate about a central axis of the door shaft 120 as a rotation axis (the central axis of the door shaft 120 is the rotation direction of the swing arm). The swing arm body 110 includes a U-shaped frame and a panel fixed in the U-shaped frame, wherein two ends of the U-shaped frame are fixed on the door shaft 120, and form a rectangular frame together with the door shaft 120, so as to facilitate sliding connection between the swing arm 100 and a rotation matching mechanism described below.

In order to ensure that the free end of the swing arm 100 slides smoothly along the first linear slide rail 321, the linear driving mechanism of the present utility model further includes a second linear slide rail 323 and a second linear slide block 324, the second linear slide block 324 is slidably fitted on the second linear slide rail 323, the second linear slide rail 323 is fixedly disposed parallel to the first linear slide rail 321, preferably, the first linear slide rail 321 may be fixedly mounted at the bottom of the accommodating groove 201, and the second linear slide rail 323 may be fixedly mounted at the top of the accommodating groove 201. Both ends of the door shaft 120 are rotatably coupled to the first linear slider 322 and the second linear slider 324, respectively. Referring to fig. 4, two ends of the door shaft 120 are respectively mounted on the first linear slider 322 and the second linear slider 324 by means of the clamp spring 121 and the bearing 122, so as to realize rotational connection between the two ends of the door shaft 120 and the first linear slider 322 and the second linear slider 324, respectively.

The rotation engagement mechanism of the present utility model includes a fixed portion 410 and a rotating portion 420, the rotating portion 420 being rotatably coupled to the fixed portion 410. The swing arm body 110 is slidably connected to the rotating portion 420 along the extending direction from the connecting end to the free end of the swing arm 100, so as to facilitate the sliding connection between the swing arm body 110 and the rotating portion 420, in this embodiment, a through hole is formed in the rotating portion 420, and the frame of the swing arm body 110 passes through the through hole of the rotating portion 420 and can slide freely in the through hole. The fixing portion 410 is fixed at a position along the length direction of the first linear slide 321, and the fixing portion 410 may be fixedly mounted on the outer side of the first linear slide 321, or the fixing portion 410 is directly fixedly mounted on the accommodating groove 201, so that when the door shaft 120 moves linearly along the first linear slide 321, the door shaft 120 can rotate on the first linear slide 322 through the cooperation of the fixing portion 410 and the rotating portion 420 and the sliding connection between the rotating portion 420 and the swing arm body 110, so as to complete the door opening and closing action of the gate.

In this embodiment, the fixing portion 410 is fixed at the position of the first linear rail 321 in the length direction, in other embodiments, the maximum stroke of the fixing portion 410 along the first linear rail 321 may be smaller than the maximum stroke of the first linear slider 322 along the first linear rail 321, and a certain limit on the position of the free end of the swing arm 100 in the length direction of the first linear rail 321 may be formed, so that the swing arm 100 rotates, which is not limited to this embodiment, but in this case, the rotation angle of the swing arm 100 is obviously smaller than the position fixing of the fixing portion 410 in the length direction of the first linear rail 321.

Since the function of the rotation matching mechanism is to limit the position of the free end of the swing arm 100 in the length direction of the first linear rail 321, the position of the rotation matching mechanism on the gate chassis 200 may be various, preferably, the rotation matching mechanism is disposed in the accommodating groove 201, and the rotation matching mechanism may be disposed at the bottom, top or other height positions of the accommodating groove 201 in the gate height direction, i.e. the extending direction of the gate shaft 120, preferably, the position of the bottom, i.e. the position near the first linear rail 321 in this embodiment. It will be appreciated that the closer the rotation engagement mechanism is to the first linear rail 321, the greater the angle at which the swing arm 100 rotates when the first linear slider 322 slides the same distance on the first linear rail 321.

In order to ensure that the swing arm 100 can be received in the receiving slot 201 when the swing arm 100 rotates positively and negatively, in this embodiment, the position of the rotation matching mechanism in the length direction of the first linear rail 321 is set in the middle of the first linear rail 321, and in other embodiments, a position slightly eccentric to the middle of the first linear rail 321 may be selected, which is not limited to the middle position of the first linear rail 321 in this embodiment.

The rotation engagement mechanism of the present utility model is not limited to the above-mentioned engagement structure of the fixed portion 410 and the rotating portion 420, but may be other engagement structures, such as a rack-and-pinion engagement structure (a rack is fixedly mounted on the first linear rail 321, a gear is fixedly mounted on the door spindle 120), or a structure shown in fig. 2, in which only the fixed portion 410 is maintained, and a bar-shaped hole is formed in the swing arm body 110 along the extending direction from the connecting end to the free end of the swing arm 100, the fixed portion 410 is inserted into the bar-shaped hole, the fixed portion 410 can slide along the bar-shaped hole, and the function of rotating the swing arm 100 can also be performed when the first linear slider 322 is along the first linear rail 321.

The principle of opening the door of the present utility model is described below:

in the door closing state, when the door needs to be opened in one direction, referring to fig. 5 (a) to (c), the motor 311 drives the first linear slider 322 to move on the first linear slider 321, the first linear slider 322 moves from the middle of the first linear slider 321 to one end of the first linear slider 321, and drives the door shaft 120 to move to the boundary, during the movement of the first linear slider 322, the rotating portion 420 in the rotating mechanism rotates on the fixed portion 410 due to the limitation of the rotating mechanism, and meanwhile, the swing arm body 110 and the rotating portion 420 slide relatively, so that the door shaft 120 rotates on the first linear slider 322 while the door shaft 120 moves along the first linear slider 322 together, and the movement mode of the swing arm 100 is a combined movement of linear movement and rotational movement, thereby shrinking into the accommodating groove 201 of the door chassis 200. Therefore, all the space of the accommodating groove 201 of the gate case 200 can be used for accommodating the swing arm 100, so that the longer swing arm 100 can be accommodated in the gate, and the requirement of a wide channel of the gate is met.

When the door is closed, the motor 311 drives the first linear slider 322 to reversely move on the first linear slide rail 321, the first linear slider 322 returns to the middle part of the first linear slide rail 321 from one end of the first linear slide rail 321, and the swing arm 100 gradually extends out of the accommodating groove 201 of the gate case 200.

When the gate needs to be opened in the other direction, refer to fig. 5 (d) to (f), the same principle is as above.

The door opening and closing mode of the gate has the following advantages:

in the door opening and closing process of the gate, the motor 311 drives the first linear slide block 322 to do uniform linear motion on the first linear slide rail 321. The initial distance between the first linear slider 322 and the rotating portion is smaller when the door is opened, and the initial distance between the first linear slider 322 and the rotating portion is larger when the door is closed.

Referring to fig. 6, since the linear movement speed of the first linear slider 322 on the first linear rail 321 is uniform, the moving distance of the first linear slider 322 on the first linear rail 321 is x in the same time, i.e. the moving distance of the connecting end of the swing arm 100 is x. As can be seen, when the first linear slider 322 moves from the middle portion to the end portion of the first linear slide rail 321 by a distance x during the door opening process, the swing arm 100 rotates by an angle Φ1; when the distance that the first linear slide block 322 moves from the end part of the first linear slide rail 321 to the middle part in the door closing process is x, the rotation angle of the swing arm 100 is phi 2; it can be seen that Φ1 is obviously greater than Φ2, that is, in the same time, the rotation angle of the swing arm 100 in the door opening process is greater than the rotation angle of the swing arm 100 in the door closing process, so that the angular velocity of the swing arm 100 in the door opening process is greater than the angular velocity of the swing arm 100 in the door closing process, the linear velocity of the edge of the swing arm 100 in the door opening process is greater, that is, the door opening speed is greater than the door closing speed, the door opening speed is fast, and the door closing speed is slow (no pedestrian is reached).
