Description

Technical Field

[0001] This utility model relates to the field of electric door unlocking technology, and in particular to an intelligent recognition and unlocking drive device for electric doors. Background Technology

[0002] Currently, most motor-driven revolving door locking structures employ electromagnetic locks or mechanical latches. Electromagnetic locks engage when energized and unlock when power is cut off; mechanical latches rely on spring force to engage a locking block with gear teeth, requiring manual operation of an unlocking lever to disengage. These structures are widely used in shopping malls, office buildings, and other locations, aiming to ensure door stability after closure through the coordination of motor drive and locking. However, existing designs exhibit weak linkage between the locking and drive systems, with unlocking often relying on a single trigger mechanism. For example, electromagnetic locks unlock solely by power-off, and mechanical latches require separate operation of the unlocking component, making it difficult to meet the security and convenience requirements of complex usage scenarios.

[0003] The existing revolving door locking structure has insufficient locking reliability. Electromagnetic locks are prone to accidental unlocking due to power outages. The springs of mechanical latches weaken after long-term use, which may cause the latch and the tooth groove to loosen, making the door body susceptible to displacement due to external forces. The unlocking linkage is poor, and the unlocking action lacks rigid connection with the motor drive. If the door is unlocked manually, the motor must be restarted to open it, which is a cumbersome operation. Thirdly, there are safety hazards. In some structures, the door body may be directly driven to rotate when the motor is accidentally started. If the lock is not completely released at this time, it is easy to cause rigid collision between the gear and the latch, resulting in wear or even jamming of the parts.

[0004] Therefore, a new intelligent recognition and unlocking drive device for electric doors is proposed to solve the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this utility model is to provide an intelligent identification and unlocking drive device for electric doors. By setting up a detection component, it solves the problems of insufficient locking reliability of existing revolving door locking structures, electromagnetic locks being easily unlocked due to power outages, mechanical buckle springs weakening after long-term use, which may cause the locking block and the tooth groove to loosen, making the door body easily pushed by external forces and displaced; poor unlocking linkage, the unlocking action and motor drive lack rigid connection, such as the need to start the motor to open the door after manual unlocking, which is cumbersome; and thirdly, safety hazards, some structures may directly drive the door body to rotate when the motor is accidentally started. If the lock is not completely released at this time, it is easy to cause rigid collision between the gear and the locking block, resulting in component wear or even jamming.

[0007] 2. Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to an intelligent identification and unlocking drive device for electric doors, comprising a rotating column, a locking block mounted on the rotating column, a telescopic rod mounted on one end of the locking block, a support plate mounted on the end of the locking block near the telescopic rod, an installation cylinder mounted through the support plate, the other end of the telescopic rod being installed inside the installation cylinder, a sliding groove provided on the installation cylinder, a locking rod mounted in the sliding groove, the locking rod being connected to the telescopic rod, a gear mounted on one side of the locking block, the tooth groove of the gear being connected to the tooth block, a threaded column mounted on the bottom end of the gear, and a threaded cylinder mounted on the threaded column.

[0010] Furthermore, a first spring is installed at the end of the latch block near the telescopic rod. The first spring is connected to the support plate. This design allows the gear to rotate when the door panel is closed. When the gear rotates, it drives the latch block to rotate outward. After the latch block rotates outward and leaves the tooth groove it was in, the spring will pull the latch block back, which can prevent the gear from causing the door panel to rotate at any time.

[0011] Furthermore, a bracket is installed on the locking rod, and a sliding rod is installed at the other end of the bracket. The sliding rod is installed inside the air rod, and a cylinder is installed at the other end of the air rod. This design allows the air rod to be retracted by the cylinder. The air rod drives the bracket to move outward through the sliding rod, and the bracket then drives the telescopic rod to move through the locking rod. When the telescopic rod moves, it drives the locking block to rotate around the rotating column and leave the slot of the gear, thereby allowing the gear to rotate continuously.

[0012] Furthermore, a second spring is installed at the end of the sliding rod away from the bracket, and the other end of the second spring is connected to the bottom end of the inner side wall of the gas rod. This design can reduce vibration by means of the spring when the entire device is subjected to vibration or other conditions.

[0013] Furthermore, a support rod is installed at the bottom of the cylinder, and a fixing block is installed at the bottom of the support rod. This design can stably fix the cylinder.

[0014] Furthermore, a second horizontal plate is installed at the bottom of the rotating column, a vertical plate is installed at one end of the second horizontal plate, a first horizontal plate is installed at the upper end of the vertical plate, a rotating shaft is installed through the first horizontal plate, a motor is installed at the end of the first horizontal plate away from the rotating shaft, the motor is connected to the first horizontal plate, the rotating shaft is connected to the end of the gear away from the threaded column, a sleeve is installed on the rotating column, and a door panel is installed on the sleeve. This design allows the electric door to open and close by starting the motor, which drives the sleeve to rotate through the rotating shaft, and the sleeve then drives the door panel to rotate.

[0015] Furthermore, two symmetrical mounting plates are installed on the first horizontal plate, and a camera is installed on either of the opposite mounting plates. This design can capture faces with the cameras and immediately upload the data to an external terminal for recognition.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] This invention significantly improves the safety and reliability of revolving doors through a linkage structure of "locking rod - telescopic rod - locking block": After the door is closed, the locking block engages with the gear teeth to form a rigid lock. Unlocking is only possible by pulling the telescopic rod open and disengaging the locking block from the teeth, preventing accidental unlocking due to electromagnetic lock failure or spring decay. The unlocking action is forcibly linked to the motor drive; the motor can only rotate the door after the locking block is completely disengaged, preventing component collision and wear. Furthermore, this structure does not rely on electronic components; the purely mechanical linkage enhances stability in harsh environments. Operationally, unlocking control is achieved through a single locking rod, simplifying the process while ensuring the safety logic of "no opening without unlocking," thus extending the device's lifespan.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-5As shown, this embodiment is an intelligent identification and unlocking drive device for electric doors, including a rotating column 110. A locking block 111 is installed on the rotating column 110. A telescopic rod 112 is installed at one end of the locking block 111. A support plate 113 is installed at the end of the locking block 111 near the telescopic rod 112. An installation cylinder 114 is installed through the support plate 113. The other end of the telescopic rod 112 is installed inside the installation cylinder 114. A sliding groove 115 is formed on the installation cylinder 114. A locking rod 280 is installed, which is connected to the telescopic rod 112. A gear 120 is installed on one side of the locking block 111, and the tooth groove of the gear 120 is connected to the tooth block. A threaded post 121 is installed at the bottom of the gear 120, and a threaded cylinder 122 is installed on the threaded post 121. A first spring 116 is installed at the end of the locking block 111 near the telescopic rod 112, and the first spring 116 is connected to the support plate 113. A second horizontal plate 330 is installed at the bottom of the rotating column 110. A vertical plate 310 is mounted on one end of the second horizontal plate 330. A first horizontal plate 320 is mounted on the upper end of the vertical plate 310. A rotating shaft 420 is mounted through the first horizontal plate 320. A motor 410 is mounted on the end of the first horizontal plate 320 away from the rotating shaft 420. The motor 410 is connected to the first horizontal plate 320. The rotating shaft 420 is connected to the end of the gear 120 away from the threaded post 121. A sleeve 430 is mounted on the rotating post 110. A [missing information - likely a device or component] is mounted on the sleeve 430. Door panel 440; A bracket 270 is installed on the locking rod 280, and a sliding rod 250 is installed on the other end of the bracket 270. The sliding rod 250 is installed inside the gas rod 240, and a cylinder 230 is installed on the other end of the gas rod 240. A second spring 260 is installed on the end of the sliding rod 250 away from the bracket 270, and the other end of the second spring 260 is connected to the bottom end of the inner side wall of the gas rod 240. A support rod 220 is installed at the bottom end of the cylinder 230, and a fixing block 210 is installed at the bottom end of the support rod 220.

[0033] Working principle: When locking the door is required, motor 410 is started. Motor 410 drives sleeve 430 to rotate via rotating column 110. When sleeve 430 rotates, it drives door panel 440 to rotate, thus closing the door. Rotating column 110 drives gear 120 to rotate. When gear 120 rotates, it pushes block 111 to one side. Regardless of how block 111 rotates, after gear 120 stops rotating, it will rotate back under the action of first spring 116 and lock gear 120, preventing gear 120 from locking. The rotation phenomenon caused by cylinder 20 causes the door panel 440 to open. When the door needs to be opened, cylinder 230 is activated to retract cylinder 240. When cylinder 240 retracts, it drives bracket 270 to move outward via sliding rod 250. When bracket 270 moves, it drives telescopic rod 112 to move via locking rod 280. When telescopic rod 112 moves, it drives locking block 111 to rotate in the opposite direction, thereby causing locking block 111 to completely disengage from the tooth groove of gear 120. At this time, gear 120 rotates without resistance, thereby allowing door panel 440 to open.

[0034] Two symmetrical mounting plates 340 are installed on the first horizontal plate 320, and a camera 350 is installed on either of the opposite mounting plates 340.

[0035] Working principle: During operation, the two cameras 350 will capture the facial information of the people at both ends of the door panel 440 and upload it to the network system for recognition. If the conditions are met, the door can be opened or closed.
