Abstract

The invention belongs to rail transit shielding door/safety door locking equipment, and relates to an electronic locking device applicable for rail transit semi-high shielding door locking equipment,in particular to a mechanism and method for locking and unlocking an urban rail transit semi-high shielding door. The mechanism is characterized by at least comprising a swing handle (1), a guide wheel component (2), connecting steel wires (3), an unlocking component (4), a lock (5), an electromagnetic locking component (6), a travel switch (7), a locking component (8) and an electromagnet (9); the handle (1) is connected to the unlocking component (4) through the guide wheel component (2) by virtue of the connecting steel wires (3); and the unlocking component (4) is connected to the lock through a lever; the unlocking component (4) is connected to the lock which is provided with the electromagnetic locking component (6). The mechanism and method for locking and unlocking the urban rail transit semi-high shielding door have the advantages of a simple structure, easy maintenance, installation space saving and low manufacturing and maintenance cost.

Example Embodiment

[0021] Such as figure 1 , figure 2 , image 3 As shown, an urban rail transit half-height shielded door locking and unlocking mechanism is provided, which is characterized in that it at least includes: a rotating handle 1, a guide wheel assembly 2, a connecting wire 3, an unlocking assembly 4, a lock 5, and an electromagnetic locking assembly 6. , Stroke switch 7, locking assembly 8, electromagnet 9, device fasteners. The fasteners are mainly used to connect the entire device to the door. The handle 1 is connected to the unlocking assembly 4 through the connecting wire 3 through the guide wheel assembly 2; The assembly 4 is connected with the lock head 5 through a lever; the unlocking assembly 4 is connected with the lock head 5, and the lock head 5 has an electromagnetic locking assembly 6 on it.
[0022] As shown in FIG. 7, the electromagnetic lock assembly 6 includes a travel switch 7, a lock assembly 8, and an electromagnet 9. The travel switch 7 and the electromagnet 9 are connected to the lock assembly 8 respectively. The electromagnetic locking assembly 6 is mainly used for locking the lock. Normally, the electromagnetic locking assembly 6 is installed inside the door side box through the mounting seat. During the unlocking process, the electromagnet 9 is energized, and the locking assembly 8 is attracted by the electromagnet. Under the action of, it can move in the axial direction, that is, the direction C as shown in Figure 7. The unlocking component 4 (area 2) is composed of the unlocking component 4, the lock head 5 and the device fasteners. Normally, the component will be fixed in the mounting bracket On the door guide rail, during the door opening/closing movement, the door moves linearly along the A direction shown in Figure 7. When the door is closed, the lock head 5 moves along the A direction and is about to reach the locking position. When the closing component 8 collides, the locking component 8 will be affected by the lift force under the action of the collision force to realize the locking function. When the door needs to be manually unlocked, under the action of the unlocking force, the unlocking assembly 4 rotates along the axis of rotation shown in FIG. 7 so that the unlocking assembly 4 and the locking assembly 8 are displaced in the B direction to realize the unlocking function and ensure the door The body opens normally.
[0023] Locking process: such as Figure 4 , The door body and the lock head 5 move from the initial position (the door is in the normal open state) to the locked position. During this process, the door body drives the lock head 5 to move linearly along the A direction. After the lock head 5 collides with the electromagnetic locking assembly 6 , Under the action of lift, the electromagnetic locking assembly 6 moves linearly along the B direction, and at the same time the stroke switch 7 detects the locking signal, after the lock head 5 moves to the locking position, the entire mechanism completes the automatic locking and detection process;
[0024] Automatic unlocking process: such as Figure 5 , The electromagnetic locking component 6 is energized, the electromagnet is magnetic, the attracting and locking component 8 moves linearly along the C direction, and the lock head 5 and the locking component 8 are displaced along the C direction to achieve separation, and the entire mechanism completes the automatic unlocking function
[0025] Manual unlocking process: such as Image 6 , Rotate the handle or turn the key, and drive the connecting wire to move linearly along the D direction through the guide assembly, thereby driving the lock head 5 to move linearly along the E direction. The lock head 5 and the locking assembly 6 are displaced along the E direction to achieve separation. The entire mechanism is manually completed Unlock function.
