Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electromechanical equipment, and relates to a driving device, in particular to a locking system of the driving device. BACKGROUND

[0002] In rail transit, in order to ensure the absolute safety of trains and passengers when they get on or off the platform, prevent passengers from jumping off the track or falling to the platform below, it is necessary to set up a platform door on the platform.

[0003] At present, the door body assembly of the platform door is generally composed of movable doors and fixed doors, and when the door is closed, the two movable doors are folded together and locked by a locking mechanism to prevent external force from opening; when the door is opened, the locking mechanism can be automatically unlocked, and the two movable doors are separated from each other.

[0004] However, the automatic unlocking of the existing locking mechanism is realized by an electromagnet or other power supply electronic components, that is, it needs to rely on a power source (electromagnet) to realize. For example, the application number 201020656124.2 discloses a locking and unlocking device for rail transit platform shielding door, which comprises a lock seat, a locking mechanism, an electromagnetic unlocking mechanism, a manual unlocking mechanism and a signal generating mechanism installed on the lock seat. The locking mechanism is arranged on the front side of the lock seat and comprises left and right locking blocks and left and right locking tongues which are symmetrically arranged. The left and right locking blocks and the left and right locking tongues are rotatably installed on the lock seat. The left and right locking blocks are connected by a locking block return spring, and the left and right locking tongues are connected by a locking tongue return spring. The left locking block and the left locking tongue form a locking and unlocking relationship, and the right locking block and the right locking tongue form a locking and unlocking relationship. The locking and unlocking of the movable door is realized by limiting the movable door limiting pin connected with the movable door through the left and right locking blocks. When the rail transit shielding door is unlocked and opened, the electromagnetic unlocking bracket is driven to move by the electromagnet after being powered on, so as to drive the locking tongue transmission pin to act, and the restriction on the left and right locking blocks is released. After power failure or power off, the automatic unlocking force is lost, thereby leaving a safety hazard.

[0005] The electromagnet itself has a high failure rate and a short service life. At the same time, the electromagnet is prone to jamming and burning under overheating conditions. In addition, the electromagnet is affected by current, further increasing the failure rate. In the low-temperature working condition, there is a condensation (water droplet) phenomenon, which also affects the service life.

[0006] Therefore, it is urgent to design a new locking device to overcome at least part of the above-mentioned defects of the existing locking device. SUMMARY

The second component B includes a first limiting mechanism 201. When the first component A is in a second operating range, the first pushing mechanism 101 engages with the first limiting mechanism 201, thereby pushing the second component B into motion.

[0139] The third component C includes a first gear 305, a second rack 306, and a second gear 307. In one embodiment, the first gear 305 and the second gear 307 are connected via a rotating shaft 308.

[0141] The first gear 305 is engaged with the first rack 105; when the first rack 105 moves in the first movement interval (the interval in which the second part B moves relative to the first part A), the first rack 105 drives the first gear 305 to rotate, the first gear 305 drives the second gear 307 to rotate, and thus drives the second rack 306 to move. When the first rack 305 moves in the second movement interval (the interval in which the second part B moves to the movement direction of the first part A after the first part A starts to move), the first part A, the second part B and the third part C are jointly driven.

[0142] In an embodiment of the present application, the second gear 307 can be connected with the lock body, and the second gear 307 can be rotated to realize unlocking.

[0147] The third component C includes a second rotating mechanism 310, a second rotating shaft 311 and a third connecting member 312; the second rotating mechanism 310 is connected to the first rotating mechanism 106 and can rotate under the drive of the first rotating mechanism 106; the first end of the third connecting member 312 is connected to the second rotating mechanism 310 and can move under the drive of the second rotating mechanism 310; the third connecting member 312 is provided with a second rotating shaft 311, and can rotate with the second rotating shaft 311 as a fulcrum under the drive of the second rotating mechanism 310.

The synchronous pulley 401 has an output shaft 402, which is connected to the first rotating mechanism 106 via the output shaft and can drive the first rotating mechanism 106 to rotate.

[0149] When the first rotating mechanism 106 is in the first action range (the first action range here refers to the angular range of the rotation process), the second rotating mechanism 310 rotates under the action of the first rotating mechanism 106, the limiting groove 107 fails to touch the limiting platform 204, and the second component B does not move; while the third component C can drive the lock body to unlock during this action process.

[0150] When the first rotating mechanism 106 is in the second action range (the second action range here refers to the angular range of the rotation process), the second component B is restricted by the limit table 204 from continuing to rotate the first rotating mechanism 106 relative to the second component B. The first component A and the second component B form a whole together and are driven by the driving mechanism (for example, the second component B is driven to rotate along the belt). Figure 4-2 ), thereby driving the load connected to the second component B.

The worm gear 322 can connect to a locking mechanism to unlock the lock.

[0152] Can be combined Figure 4-1 、 Figure 5-1 In one embodiment of the present invention, when the first rotating mechanism 106 is in the first action range (the first action range here refers to the angular range of the rotation process), the second rotating mechanism 310 rotates under the action of the first rotating mechanism 106, and the limit groove 107 fails to touch the limit platform 204. After the first component A drives the turbine 321 to rotate (the second component B does not move at this time), it can drive the worm 322 to move; the worm 322 can connect to the locking mechanism, thereby achieving unlocking.

[0153] When the first rotating mechanism 106 is in the second action range (the second action range here refers to the angular range of the rotation process), the second component B is restricted by the limit platform 204 from continuing to rotate the first rotating mechanism 106 relative to the second component B. The first component A and the second component B together form a whole, which is driven by the driving mechanism to move, and can thereby drive the load connected to the second component B.
