Abstract
Description
Technical Field
[0001] This application relates to the field of speed gate technology, and more specifically, to a direct-drive speed gate. Background Technology
[0002] Speed gates are intelligent access control systems primarily used for personnel entry and exit management. They automatically open and close the gate panels through an electronic system, thereby achieving efficient and secure passage management.
[0003] In related technologies, speed gates consist of a control system, an authentication module, a sensor system, and an actuator. The authentication module includes multiple methods such as card swiping, QR code scanning, fingerprint recognition, and facial recognition. The sensor system detects obstacles and monitors passage. The control system drives the gate to open and close, and the actuator uses components such as motors or electromagnetic clutches to ensure millisecond-level response speed and stability.
[0004] However, during routine maintenance of the speed gate or when the swing gate motor malfunctions, the motor is usually locked, preventing the speed gate from being manually opened and automatically closed under external force. In this situation, pedestrians needing emergency passage or normal passage will be obstructed because the gate cannot be opened, severely impacting passage efficiency. Utility Model Content
[0005] In view of this, embodiments of this application provide a direct-drive speed gate to solve the problems in related technologies.
[0006] The problem of speed gates failing to open passively or close automatically when under maintenance or when the swing gate motor is not in operation.
[0007] To achieve the above objectives, the embodiments of this application provide the following technical solutions:
[0008] A direct-drive speed gate, comprising:
[0009] Columns;
[0010] A swing gate motor is installed inside the column, and its drive shaft extends vertically and is fixedly connected to the gate panel.
[0011] A passive access control system includes a sprocket coaxially fixedly mounted on the top of the drive shaft. A chain is externally engaged with the sprocket. The first end of the chain is fixedly connected to the sprocket, and the first end of the chain passes through the side plate of the column and extends to its outside. The second end of the chain is fixedly connected to a slide rod. A return spring is sleeved on the slide rod, which is slidably connected to the side plate of the column and abuts against the return spring through a second limiting plate.
[0012] In some possible implementations, the other end of the slide bar is provided with a first limiting plate, which is used to abut against the other end of the return spring.
[0013] In some possible implementations, the side of the door panel is detachably fixed to the drive shaft by clamps.
[0014] In some possible implementations, the drive shaft of the swing gate motor can passively rotate following the transmission of the passive access control system, and the swing gate motor is in a non-operating state when passively rotating.
[0015] In some possible implementations, the sprocket is fixed to the drive shaft by a key connection, and the number of its teeth is adapted to the rotation angle of the door panel.
[0016] In some possible implementations, a linear bearing is provided at the sliding engagement point between the slide rod and the column side plate. The linear bearing is embedded in the through hole of the column side plate to reduce the sliding friction of the slide rod.
[0017] The direct-drive speed gate provided in this application embodiment has at least the following beneficial effects:
[0018] In the direct-drive speed gate provided in this embodiment, a passive access control system is installed inside the column. This system is assembled with the swing gate motor, drive shaft, and door panel. The passive access control system allows pedestrians to directly push the door panel to passively rotate and open it when the swing gate motor is under maintenance or not in operation. After the pedestrian has passed through, the door panel automatically closes under the force of the return spring. This structural design ensures normal passage of the speed gate during maintenance without requiring an additional power source, offering advantages such as simple structure and high reliability.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1-5 As shown in the figure, the direct-drive speed gate provided in this embodiment includes a column 100, a swing gate motor 200, and a passive access control system. The column 100 refers to the gate column used with the direct-drive speed gate, primarily for the physical separation and control of vehicle or pedestrian traffic, and is installed at designated entrances and exits. The column 100 internally houses various components of the direct-drive speed gate, such as a control system, authentication module, sensor system, and actuators. The above content is well-known to those skilled in the art, and this embodiment will not elaborate further; only the technical solution to the problem to be solved is described.
[0029] The column 100 is a hollow stainless steel structure, inside which a bracket for the swing gate motor 200 is fixedly installed. The swing gate motor 200 is vertically mounted on the bracket by bolts, and the drive shaft 300 of the swing gate motor 200 extends upwards in the vertical direction. Furthermore, the drive shaft 300 and the door panel 400 are detachably and fixedly connected by a clamp 900. Specifically, the clamp 900 is fixedly connected to the side of the door panel 400, and the clamp 900 wraps around the drive shaft 300 and is locked with bolts. Therefore, after the swing gate motor 200 is started, it can drive the door panel 400 to rotate, thereby realizing the opening and closing of the direct-drive speed gate.
[0030] like Figure 4 and Figure 5As shown, this embodiment also includes a passive access control system. This system allows the door panel 400 to passively open and close and automatically close under external force when the swing gate motor 200 is in the closed state. Specifically, the passive access control system includes a sprocket 500, a chain 600, a slide bar 700, and a return spring 800. The sprocket 500 is mounted on the top of the drive shaft 300 via a coaxial key connection, and a half-circle chain 600 is meshed with the outside of the sprocket 500. The first end of the half-circle chain is welded to the teeth of the sprocket 500, and the second end of the half-circle chain passes through the side plate of the column 100 and extends to its exterior.
[0031] Continue as Figure 4 and Figure 5 As shown, a slide rod 700 is fixedly connected to the second end of the semi-circular rack. The slide rod 700 is a cylindrical metal rod structure that passes through the side plate of the column 100 and extends to its exterior. A return spring 800 is sleeved on the outside of the slide rod 700. A second limiting plate 720 is fixedly installed at the end of the slide rod 700 away from the chain 600, and it abuts against the return spring 800 through the second limiting plate 720. In addition, the slide rod 700 is also slidably connected to the side plate of the column 100.
[0032] The following is combined with Figures 1-5 The working principle and working process of the direct-drive speed gate provided in the embodiments of this application are described.
[0033] During normal operation: After the swing gate motor 200 starts, it drives the drive shaft 300 to rotate, which in turn drives the door panel 400 to rotate and open. At this time, the passive access control system moves synchronously with the drive shaft 300, and the elasticity of the return spring 800 does not affect the motor drive. Preferably, the return spring 800 is a high-quality spring with high fatigue resistance.
[0034] When the swing gate motor 200 is under maintenance or not in operation: If a pedestrian wants to pass through the speed gate, they can directly push the door panel 400 to rotate it. Since the door panel 400 and drive shaft 300 are fixedly connected, the door panel 400 will drive the drive shaft 300, causing the swing gate motor 200 to rotate passively. Simultaneously, the sprocket 500 will rotate counter-clockwise synchronously with the drive shaft 300, and will pull the slide bar 700 through the chain 600, causing the return spring 800 to compress. After the pedestrian passes through the speed gate, the return spring 800 returns to its original state under the action of its elasticity, and pushes the slide bar 700 to slide towards the side plate of the column 100. At the same time, the chain 600 pulls the sprocket 500 to rotate counter-clockwise, the drive shaft 300 rotates counter-clockwise synchronously with the sprocket 500, and the door panel 400 automatically closes and resets.
[0035] In the direct-drive speed gate provided in this embodiment, a passive access control system is installed inside the column 100. This passive access control system is assembled and used with the swing gate motor 200, drive shaft 300, and door panel 400. When the swing gate motor 200 is under maintenance or not in operation, the passive access control system allows pedestrians to directly push the door panel 400 to passively rotate and open it. After the pedestrian has passed through, the door panel 400 automatically closes under the elastic force of the return spring 800. This structural design ensures normal passage of the speed gate during maintenance without requiring an additional power source, offering advantages such as simple structure and high reliability.
[0036] In some embodiments, a first limiting plate 710 is provided at the other end of the slide rod 700, which abuts against the other end of the return spring 800. By providing a first limiting plate 710 and a second limiting plate 720 at both ends of the return spring 800, the compression stroke and installation position of the return spring 800 can be precisely limited, preventing the return spring 800 from shifting, falling off, or being over-compressed and failing during sliding. Simultaneously, the above structure can also evenly transmit the elastic force of the return spring 800 to the slide rod 700 and the side plate of the column 100, ensuring stable transmission of the passive access control system under force and improving the reliability of the door panel 400's passive opening and automatic closing.
[0037] In some embodiments, the drive shaft 300 of the swing gate motor 200 can passively rotate following the transmission of the passive access control system, and the swing gate motor 200 is in a non-operating state during passive rotation. This avoids resistance caused by internal electromagnetic locking during passive rotation of the swing gate motor 200, ensuring pedestrians can easily push the door panel 400. Furthermore, it prevents damage to internal components from the passive rotation of the swing gate motor 200 in a non-operating state, thereby extending the service life of the swing gate motor 200 and ensuring smooth passage during maintenance or malfunction.
[0038] In some embodiments, the sprocket 500 and the drive shaft 300 are fixed together by a key connection, and the number of teeth on the sprocket 500 is adapted to the rotation angle of the door panel 400. The key connection is simple in structure and transmits large torque, ensuring that the sprocket 500 and the drive shaft 300 rotate synchronously, avoiding transmission failure due to slippage. The matching of the number of teeth on the sprocket 500 to the rotation angle of the door panel 400 allows for precise control of the chain 600's pulling stroke, ensuring that the rotation angle of the door panel 400 when passively opened meets passage requirements. This prevents the angle from being too small to obstruct passage or too large to cause structural interference, thereby improving the stability and safety of passive opening.
[0039] In some embodiments, a linear bearing is provided at the sliding engagement point between the slide rod 700 and the side plate of the column 100. The linear bearing is embedded in the through hole of the side plate of the column 100 to reduce the sliding friction of the slide rod 700. The linear bearing converts the sliding friction between the slide rod 700 and the side plate of the column 100 into rolling friction, significantly reducing frictional resistance. This makes it easier for pedestrians to push the door panel 400, improving the convenience of passive opening. At the same time, it also reduces the wear of the slide rod 700 and the side plate of the column 100, thereby extending the service life of related components and ensuring that the passive access control system can still operate flexibly and maintain the stability of the automatic reset function after long-term use.

For example, a layer may be located between the top and bottom surfaces of the continuous structure, or between any pairs of lateral planes at the top and bottom surfaces. A layer may extend laterally, vertically, and / or along a tapered surface. A substrate may be a layer, and may include one or more layers, and / or may have one or more layers located on, above, and / or below it. A layer may include multiple layers.
