It can be seen that the straight arm type barrier gate and the folding arm type barrier gate both rotate upwards when the gate is opened. In this process, the gravity of the barrier gate needs to be overcome, which is a laborious process.
FIG. 3 is an exploded view of the structure of a barrier device according to an exemplary embodiment; fig. 4 is a schematic diagram illustrating two types of barriers in the related art according to an exemplary embodiment in comparison with the gravity center position of the blocking device provided by the embodiment of the present invention in the open state.
As shown in fig. 3, an embodiment of the present invention provides a blocking device, including: transmission assembly 1, blocking assembly 2, and drive assembly 3. Wherein, transmission assembly 1 and block subassembly 2 and rotate and be connected, transmission assembly 1 is controlled by drive assembly 3, rotates around at least a pivot. And when the transmission assembly 1 is controlled by the driving assembly 3 to rotate downwards around at least one rotating shaft, the blocking assembly 2 rotates upwards by taking the rotating connection part with the transmission assembly 1 as an axial direction.
Wherein, the transmission component 1 and the blocking component 2 jointly realize the blocking effect. In other words, when the blocking device is used as a barrier, the transmission assembly 1 and the blocking assembly 2 function as a gate rod. When the blocking device provided by the embodiment of the invention is used, the driving component 3 controls the transmission component 1 to rotate downwards around the rotating shaft, so that the blocking component 2 rotates upwards to realize opening.
When the blocking device is opened, the transmission assembly 1 is rotated downwards, in the process, the gravity of the transmission assembly 1 is assisted, and therefore, the opening process is labor-saving for the transmission assembly 1. Compared with a straight arm type brake lever and a folding arm type brake lever in the related art, the blocking device provided by the embodiment of the invention has a labor-saving process when being opened.
And, drive the whole of blocking assembly 2 through drive assembly 1 and move down and realize opening, help reducing the whole centre of gravity height of drive assembly 1 and blocking assembly 2 under the open mode. As shown in fig. 4, for convenience of comparison, the sum of the lengths of the transmission assembly 1 and the blocking assembly 2 in the straight arm type brake lever, the folded arm type brake lever, and the blocking device provided by the embodiment of the present invention is equal. And H0 is the initial height of the center of gravity in fig. 4, H1 is the height of the center of gravity of the transmission assembly 1 and the blocking assembly 2 in the open state of the blocking device provided by the embodiment of the invention, and H2 and H3 are the heights of the center of gravity of the gate rods of the two gates in the open state, respectively. It can be seen that the height of the center of gravity of the transmission assembly 1 and the blocking assembly 2 of the blocking device provided by the embodiment of the invention is obviously lower than that of the two barrier gate bars in the related art. By reducing the height of the center of gravity change of the transmission assembly 1 and the blocking assembly 2 in the opening state, the power consumption required when the blocking device is opened is reduced.
The blocking device provided by the embodiment of the invention reduces the energy consumption of the blocking device in the opening process, and further can reduce the output torque of the driving assembly 3. Therefore, when the blocking device is used as a barrier gate, compared with the barrier gate provided in the related art, the opening process is more time-saving and labor-saving, quick opening can be realized, and the use convenience of the blocking device is optimized.
In one embodiment, the transmission assembly 1 is rotatably connected with the blocking assembly 2 by at least two joints. Wherein, one rotary joint realizes that the transmission component 1 drives the blocking component 2 to move downwards, which is beneficial to reducing the height of gravity center change; the other pivot joint acts as a fulcrum for the upward pivoting of the blocking assembly 2 to effect the opening of the blocking device.
In one embodiment, as shown in FIG. 3, the at least one shaft includes a first shaft A and a second shaft B. The transmission assembly 1 comprises: a first lever 11 rotating about a first axis of rotation a, and a second lever 12 rotating about a second axis of rotation B. The barrier assembly 2 comprises: a first connecting point 21, which is rotatably connected to the first lever 11, and a second connecting point 22, which is rotatably connected to the second lever 12.
In this embodiment, the first rod 11 is used to drive the blocking assembly 2 to move downwards; the second lever 12 is used to guide the movement of the blocking assembly 2 such that the blocking assembly 2 can be pivoted about the second connection site 22.
Alternatively, the first and second connection sites 21, 22 are located away from the end of the blocking assembly 2 that is turned upwards. In such a case, the length of the portion of the blocking member 2 rotated upward is increased, the length of the portion of the blocking member 2 that serves as a blocking function is extended, and the blocking range of the blocking member 2 is expanded.
Optionally, the first connection location 21 is lower or level with the first rotation axis a. Specifically, in the closed state, the transmission assembly 1 and the blocking assembly 2 are at the same horizontal position, and the first connecting position 21 is at the same height as the first rotating shaft a, so as to realize the maximum blocking range of the blocking device in the horizontal direction. The second connecting portion 22 is lower than the second rotation axis B. So that during the opening process the second lever 12 exerts a lifting force on the blocking assembly 2, effecting an upward rotation of the blocking assembly 2; during the closing process, the second lever 12 pulls the blocking member 2 to prevent the blocking member 2 from falling off around the first connecting position 21.
In this embodiment, the first and second rotational axes a and B are relatively fixed. Further, the drive assembly 3 includes: an output shaft 31 connected to the first lever 11 for driving the first lever 11 to rotate about the first rotation axis a. When the first rod 11 rotates downwards, the second rod 12 rotates downwards around the second rotation axis B in a linkage manner, and the second rod 12 drives the blocking assembly 2 to rotate upwards by taking the second connection position 22 as an axial direction. It will be appreciated that the first lever 11 is a driving shaft and the second lever 12 is a driven shaft. In this embodiment, the driving assembly 3 is provided with only one output shaft 31, which has the advantages of simple structure and easy implementation.
The movement pattern of the blocking assembly 2 is defined by the first lever 11 and the second lever 12, while the transmission assembly 1 and the blocking assembly 2 form a linkage. Fig. 5-8 are schematic views illustrating different working states of the blocking device according to an exemplary embodiment. With reference to fig. 5 to 8, the operation of the transmission assembly 1 and the blocking assembly 2 is as follows.
The starting process comprises the following steps: when the transmission component 1 drives the first connecting position 21 to rotate downward, the blocking component 2 has a downward movement tendency, and the blocking component 2 drives the second rod 12 to rotate downward along the second rotating axis B through the second connecting position 22. Simultaneously with the downward rotation of the second lever 12, the second lever 12 exerts a lifting force on the blocking assembly 2, so that the blocking assembly 2 has a tendency to move closer towards the second lever 12. At this time, the blocking assembly 2 rotates upwards with the second connecting position 22 as a fulcrum of the blocking assembly 2, so as to realize opening.
And (3) closing process: the driving assembly 3 drives the transmission assembly 1 to rotate upwards, and the first connecting position 21 rotates upwards. At this time, the blocking component 2 has an upward movement trend, and then the second rod 12 is driven to rotate upward through the second connecting position 22, so that the blocking component 2 and the transmission component 1 extend outward, and a closed state is realized.
Alternatively, the blocking assembly 2 can be rotated between a horizontal position, in which the blocking assembly 2 is in the horizontal position, and a vertical position, in which the blocking assembly 2 is in the vertical position, under the action of the transmission assembly 1 and the second lever 12.
In one embodiment, as shown in fig. 3, the blocking member 2 is provided with a lug plate protruding therefrom for connection to the transmission member 1. Optionally, the ear plates are arranged in pairs on the blocking assembly 2, and the first connection position 21 and the first rod 11 are rotatably connected through the cooperation of the ear plates and the pin shafts, and the second connection position 22 and the second rod 12 are rotatably connected. In the embodiment, a pin shaft hole is not required to be formed in the blocking component 2, so that the phenomenon of stress concentration at the hole is avoided, and the mechanical stability of the blocking component 2 is optimized.
Fig. 8 and 9 are schematic views illustrating a use state of the blocking device according to another exemplary embodiment. In one embodiment, as shown in fig. 8 and 9, the second rotating shaft B is disposed on the first rod 11, in other words, the second rod 12 is rotatably connected with the first rod 11. And, the second connection site 22 is slidably provided on the barrier assembly 2 along the barrier assembly 2.
Furthermore, the drive assembly 3 further includes: an output shaft (not shown) connected to the second lever 12 drives the second lever 12 to rotate about the second rotation axis B through the output shaft. In particular embodiments, the output shaft may be coupled to the second rod 12 via a chain, a track, or the like.
In use, the first lever 11 is rotated downwardly so that the blocking assembly 2 moves downwardly. At the same time, the second rod 12 slides in a direction away from the first rod 11, the second rod 12 exerting a lifting force on the blocking assembly 2, since the length of the second rod 12 is fixed. Further, under the combined action of the first rod 11 and the second rod 12, the blocking assembly 2 exhibits a movement tendency of rotating in the axial direction of the first connecting position 21, and the opening state is realized as shown in fig. 8.
Correspondingly, it will be appreciated that when the first lever 11 is rotated upwardly and the second lever 12 is slid in a direction approaching the first lever 11, the second lever 12 is caused to exert a depressing force on the blocking assembly 2. Furthermore, the blocking member 2 exhibits a tendency to rotate downwards in the axial direction of the first connection site 21, achieving the closed condition shown in fig. 9.
Regarding the manner of connection of the second rod 12 and the blocking assembly 2, optionally, the blocking assembly 2 comprises a slide groove arranged along the length direction, and a slide block cooperating with the slide groove, the slide block forming a second connection site 22 of the second rod 12 to the blocking assembly 2.

In one embodiment, as shown in FIG. 10, the at least one axis of rotation comprises a first axis of rotation A. The transmission assembly 1 comprises a first lever 11 rotating about a first axis of rotation a. The blocking assembly 2 is rotatably connected to the first lever 11. The driving assembly 3 includes output shafts 31 connected to the first rod 11 and the blocking assembly 2, respectively, and when the driving assembly 3 drives the first rod 11 to rotate downward around the first rotation axis a through one output shaft 31, the blocking assembly 2 is driven to rotate upward through the other output shaft 31.
Alternatively, the drive assembly 3 comprises one motor with two output shafts 31, or the drive assembly 3 comprises two motors operating in tandem. Also, the output shaft 31 may be connected to the blocking assembly 2 by a chain or a track (not shown) to drive the blocking assembly 2 to rotate.
In this embodiment, the blocking device is opened by driving the transmission assembly 1 and the blocking assembly 2 through two output shafts 31, respectively. In such a case, the second rod 12, and the second connection site 22 on the blocking assembly 2, are not required, which contributes to simplifying the structure of the transmission assembly 1 and the blocking assembly 2.

The blocking assembly 2 is rotatably connected to the first lever 11. The driving assembly 3 comprises a first driving motor for driving the first rod 11 to rotate; and a second driving motor for driving the blocking assembly 2 to rotate, wherein the second driving motor is disposed on the first lever 11.

The second rod 12 and the second connection site 22 on the blocking assembly 2 are also not required in this embodiment, which helps to simplify the construction of the transmission assembly 1 and the blocking assembly 2. However, in this way, attention is paid to controlling the weight of the second driving motor to avoid increasing the energy consumption of the first driving motor.
In one embodiment, as shown in fig. 3, the blocking device further comprises: and the support frame 4 is connected with the transmission assembly 1 and the output shaft 31.

Regarding the structure of the support frame 4, the support frame 4 illustratively has a polygonal groove, and the output shaft 31 has a projection adapted to the shape of the groove. The relative fixation of the support frame 4 and the output shaft 31 is realized by the matching of the groove and the bump, wherein the polygon can be selected from square, rectangle, hexagon and the like. Alternatively, the support frame 4 and the end of the output shaft 31 are fixed by a fastening member such as a screw.
