[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0042] In order to enable those skilled in the art in this technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0043] See Figures 1 - 3 , a quick - access gate safety protection device provided by the present application includes a main body 1, a rotating rod 2 is rotatably connected to the main body 1, a door wing 3 is fixedly arranged on the rotating rod 2, and a transmission part 4 and a one - way damping component 5 are arranged at the bottom end of the rotating rod 2; a driving part 6 is arranged in the main body 1, and the output end of the driving part 6 is connected to the transmission part 4 to realize the opening of the door wing 3; a rebound part 8 is arranged in the main body 1, the rebound part 8 is connected to the upper end of the rotating rod 2, and the rebound part realizes the closing of the door wing 3; a control system, and both the driving part 6 and the locking component 7 are in signal connection with the control system.

[0044] That is to say, the main body 1 is connected to the rotating rod 2 and realizes the stable rotation of the rotating rod 2. A door wing 3 is fixedly installed on the rotating rod 2. The main body 1, the rotating rod 2, and the door wing 3 of the present application are all symmetrically arranged with each other to form a quick - access gate safety protection device.

[0045] The transmission part 4 is installed at the bottom end of the rotating rod 2 and is connected to the output end of the driving part 6, responsible for transmitting the power of the driving part 6 to the rotating rod 2, thereby driving the opening of the door wing 3, and the rebound part stores potential energy.

[0046] The rebounding member 8 is arranged inside the main body 1 and connected to the upper end of the rotating rod 2. When the door wing 3 needs to be closed, the locking assembly 7 stops working, and the rebounding member 8 releases the stored energy to push the rotating rod 2 and the door wing 3 to close quickly and smoothly. The one-way damping assembly 5 is also arranged at the bottom end of the rotating rod 2 and is used to provide a damping force during the closing process of the door wing 3 to slow down the closing speed of the door wing 3 and avoid potential safety hazards caused by rapid closing. The one-way damping assembly 5 only functions when the door wing is closing and does not affect the opening of the door wing.

[0047] The working process of the rapid access door safety protection device of this application is as follows: The control system first receives a trigger signal from the outside, and the signal can come from an access control card, a face recognition system, or other identity verification devices. Once the signal is confirmed to be valid, the control system will immediately issue a control instruction to activate the driving member 6. After receiving the control instruction, the driving member 6 starts to work and drives the door wing 3 to open automatically to provide a passage for the passing personnel. There is a preset time period or time delay mechanism inside the control system to control the duration of the open state of the door wing. When the preset time is reached or it is detected that the passing personnel have passed, the control system will stop the work of the driving member 6. As the driving member 6 stops working, the rebounding member 8 begins to release the energy it stores and pushes the rotating rod 2 to rotate in the reverse direction, realizing the automatic and smooth closing of the door wing 3. During the closing process of the door wing 3, the one-way damping assembly 5 provides the necessary damping force to slow down the closing speed of the door wing. To sum up, a rapid access door safety protection device provided by this application, when the passing personnel fail to pass in time during the closing process of the door wing for some reason, the slow closing of the door wing reduces the harm to the passing personnel and also avoids damage to the structure of the door wing itself, thereby improving the service life of the rapid access door.

[0048] Based on the above embodiments, it further includes a locking assembly 7 arranged inside the main body 1. When the door wing 3 is at a preset open position or a preset closed position, the locking assembly 7 limits the rotation of the rotating rod 2.

[0049] That is to say, when the door wing 3 reaches the preset open position or the preset closed position, the locking assembly 7 will receive a signal from the control system to work and can firmly fix the rotating rod 2 to prevent its accidental rotation.

[0050] When it is necessary to change the state of the door wing (such as from open to closed, or from closed to open), the control system will send a signal again to instruct the locking assembly 7 to release its locking mechanism, and then the rotating rod 2 can rotate freely, thereby driving the door wing to perform corresponding actions.

[0051] Based on the above embodiments, see Figure 3, the locking component 7 includes a cylinder 71. The output end of the cylinder 71 is connected to a telescopic rod 72. One end of the telescopic rod 72 faces the rotating rod 2. The rotating rod 2 is provided with a through first locking hole 22 and a second locking hole 221. The center line of the first locking hole 22 and the center line of the second locking hole 221 are located in the same horizontal plane and are perpendicular to each other. When the door wing 3 is in the preset open position, the cylinder 71 can drive the telescopic rod 72 to penetrate into the second locking hole 221. When the door wing 3 is in the preset closed position, the cylinder 71 can drive the telescopic rod 72 to penetrate into the first locking hole 22.

[0052] That is to say, the cylinder 71 drives the telescopic rod 72 to perform telescopic movement by receiving instructions from the control system. One end of the telescopic rod 72 is connected to the output end of the cylinder 71, and the other end faces the rotating rod 2. The length of the telescopic rod 72 can be adjusted as needed to ensure that it can accurately insert into the locking hole on the rotating rod 2.

[0053] On the rotating rod 2, a through first locking hole 22 and a second locking hole 221 are designed.

[0054] The first locking hole 22 and the second locking hole 221 respectively correspond to the closed state and the open state of the door wing 3. When the door wing 3 is closed, the first locking hole 22 is aligned with the end of the telescopic rod 72; the second locking hole 221 is perpendicular to the center line of the first locking hole 22 and is in the same horizontal plane. When the door wing 3 is open, the first locking hole 22 is aligned with the end of the telescopic rod 72.

[0055] When the door wing 3 is in the preset open position, the control system issues an instruction to the cylinder 71 to drive the telescopic rod 72 to extend in the direction of the second locking hole 221. Once the telescopic rod 72 completely penetrates the second locking hole 221, the rotating rod 2 is locked to prevent it from rotating, thereby keeping the door wing 3 in the open position.

[0056] When the door wing 3 is in the preset closed position, the control system issues an instruction to the cylinder 71 again to drive the telescopic rod 72 to insert into the first locking hole 22. The rotating rod 2 is locked again, and the door wing 3 is kept in the closed position.

[0057] On the basis of the above embodiments, the locking component 7 further includes a door wing position detector. The door wing position detector is signal-connected to the control system. The door wing position detector is used to judge whether the door wing 3 is in the preset open position or the preset closed position.

[0058] That is to say, the door wing position detector is responsible for real-time monitoring of the current position of the door wing 3 and comparing it with the preset open position and closed position. Once it detects that the door wing reaches these preset positions, it will immediately send a signal to the control system to trigger the corresponding locking or unlocking operation.

[0059] Based on the above embodiments, refer to Figure 3 The driving member 6 includes a driving motor 61 and a driving gear 62 connected to the driving motor 61. The transmission member 4 is located above the one-way damping assembly 5. The transmission member 4 is a driven gear, and the driving gear 62 is meshed and connected with the driven gear.

[0060] Specifically, the driving motor 61 is connected to the driving gear 62, and then the driving gear 62 transmits the rotational power generated by the driving motor 61 to the transmission member 4 (driven gear). The driving gear 62 is matched with the driven gear to achieve meshing transmission.

[0061] Specifically, when the driving motor 61 of the present application does not work, the driving gear 62 can rotate freely, and then the rotating rod 2 can rotate in the reverse direction to close the door wing 3. The driving motor 61 can be an AC asynchronous motor without an internal braking device or locking mechanism. When the motor does not work (i.e., when it is not powered on), since there is no electromagnetic force acting on the rotor, the rotor will rotate freely due to external forces.

[0062] Based on the above embodiments, refer to Figures 4 - 5 The rebounding member 8 includes a housing 81. A through hole is provided at the center of the housing 81. A first clamping block 82 is provided on the inner wall of the through hole. A second clamping block 23 is provided on the outer wall of the top end of the rotating rod 2; an elastic member 83 is sleeved on the rotating rod 2. The rotating rod 2 can be inserted into the through hole so that one end of the elastic member 83 abuts against the first clamping block 82 and the other end abuts against the second clamping block 23.

[0063] That is to say, a through hole is provided at the center of the housing 81, and a first clamping block 82 is provided on the inner wall of the through hole as a limiting point; the second clamping block 23 is provided on the outer wall of the top end of the rotating rod 2;

[0064] The elastic member 83 is sleeved on the rotating rod 2 and stores and releases energy by abutting against the first clamping block 82 and the second clamping block 23. When the rotating rod 2 is moved by an external force, the elastic member 83 will be compressed or stretched; when the external force disappears, the elastic member 83 will release the stored energy and push the rotating rod 2 to move in the opposite direction, thereby achieving the effect of rebounding or resetting.

[0065] After receiving the instruction, the driving member 6 starts to work and transmits power to the door wing 3. During the opening process of the door wing 3, the rotating rod 2 also rotates accordingly. When the rotating rod 2 rotates, the second latch 23 also moves accordingly. During the movement of the second latch 23, due to the moving direction of the second latch 23, the elastic member 83 is compressed, thereby storing potential energy. When the door wing 3 is fully opened and reaches the preset position, the driving member 6 stops working. At the same time, the locking assembly 7 also stops working, allowing the door wing to move freely. Then, the elastic member 83 starts to release the previously stored energy, and the released energy is transmitted to the rotating rod 2 through the second latch 23, causing the rotating rod 2 to rotate in the reverse direction. The reverse rotation of the rotating rod 2 further drives the door wing 3 to move in the closing direction until the door wing is fully closed.

[0066] Based on the above embodiment, the one-way damping assembly 5 includes a one-way rotary damper 51 fixedly arranged at the bottom of the cavity of the main body 1; and a connecting member 52. The bottom end of the connecting member 52 is detachably connected to the one-way rotary damper 51. The top end of the connecting member 52 is provided with a blind hole, and the inner wall of the blind hole is provided with uniformly distributed limiting blocks. The outer wall of the bottom end of the rotating rod 2 is provided with uniformly distributed limiting grooves 21, and the limiting blocks can be clamped in the limiting grooves 21.

[0067] Specifically, the one-way rotary damper 51 can provide a damping force when the door wing is closed (i.e., when the rotating rod 2 rotates in the reverse direction), and allows the rotating rod 2 to rotate freely without generating additional resistance when the door wing is opened (i.e., when the rotating rod 2 rotates in the forward direction).

[0068] The bottom end of the connecting member 52 and the one-way rotary damper 51 are detachably connected, which is convenient for maintenance and replacement. The top end of the connecting member 52 is provided with a blind hole, and the inner wall of the blind hole is uniformly distributed with limiting blocks. The limiting blocks are matched with the limiting grooves 21 on the outer wall of the bottom end of the rotating rod 2 and can be clamped therein to achieve a stable connection between the rotating rod 2 and the connecting member 52. Through the clamping connection, the stability and accuracy of the rotating rod 2 during rotation are ensured.

[0069] When the door wing 3 needs to be closed, the rotating rod 2 starts to rotate in the reverse direction as the rebounding member 8. At this time, the one-way rotary damper 51 applies a damping force to the connecting member 52. Since the connecting member 52 and the rotating rod 2 are fixed together through the clamping connection of the limiting blocks and the limiting grooves 21, the damping force will be transmitted to the rotating rod 2, thereby slowing down the closing speed of the door wing. When the door wing is opened, the one-way rotary damper 51 allows the rotating rod 2 to rotate freely without generating additional resistance.

[0070] Based on the above embodiment, the control system further includes a control instruction recognition module. The control instruction recognition module includes a protocol capture unit for capturing service control instructions; an instruction processing unit for parsing and analyzing the instructions; and a signal transmission module for establishing a signal connection with a preset database and used for transmitting correct service instructions.

[0071] That is to say, the protocol capture unit is responsible for capturing service control instructions from an external communication network (such as Ethernet, serial communication, etc.), and can identify and receive data packets that conform to a specific communication protocol. The data packets contain instructions for controlling the express gate, and the captured data packets will be sent to the instruction processing unit for further processing.

[0072] After receiving the data packet from the protocol capture unit, the instruction processing unit first parses it to extract the control instructions and related parameters. Subsequently, the instruction processing unit compares these instructions with the preset instruction formats and rules to ensure the correctness of the instructions. More importantly, the instruction processing unit will compare with the data in the preset database. This database contains all normal and authorized control instructions and their corresponding parameter ranges. If the instruction processing unit finds a matching normal instruction in the database, it will further prepare the instruction for execution; if no matching item is found, the instruction is considered abnormal.

[0073] The signal transmission module establishes a stable signal connection with the preset database for real-time querying and comparing instruction data. When the instruction processing unit confirms that an instruction is normal and legal, the signal transmission module will be responsible for transmitting the instruction to the corresponding actuator to perform the operation.

[0074] If the instruction is identified as abnormal or unauthorized, the signal transmission module will not transmit the instruction and may trigger an alarm system or take other security measures (such as blocking the further propagation of abnormal instructions).

[0075] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0076] Specific examples are used in this article to elaborate on the principles and implementation modes of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
