Description

Technical Field

[0001] The invention belongs to the technical field of electromechanical equipment and relates to a driving device, in particular to a transmission device of the driving device. Background Art

[0002] In rail transit, in order to ensure the absolute safety of trains and passengers when entering and exiting the station and to prevent passengers from jumping off the tracks or falling under the platform accidentally, platform doors need to be installed on the platform.

[0003] At present, the door body assembly of the platform door is generally composed of a movable door and a fixed door. When closing the door, the two movable doors close together and are locked by a locking mechanism to prevent them from opening by external force. When opening the door, the locking mechanism can be automatically unlocked and the two movable doors separate from each other.

[0004] However, the automatic unlocking of the existing locking mechanism is realized by an electromagnet or other electronic components that require power, that is, it needs to rely on a power source (electromagnet) to achieve. For example, the application number is 201020656124.2, which discloses a rail transit platform screen door locking and unlocking device, including a lock seat and a locking mechanism installed on the lock seat, an electromagnetic unlocking mechanism, a manual unlocking mechanism and a signal generating mechanism. The locking mechanism is arranged on the front side of the lock seat, including symmetrically arranged left and right lock blocks and left and right lock tongues, the left and right lock blocks and the left and right lock tongues are respectively rotatably installed on the lock seat, a lock block reset spring is connected between the left and right lock blocks, a lock tongue reset spring is connected between the left and right lock tongues, a locking and unlocking relationship is formed between the left lock block and the left lock tongue, and a locking and unlocking relationship is formed between the right lock block and the right lock tongue. The locking and unlocking of the movable door is achieved by limiting the movable door limit pin connected to the movable door by the left and right lock blocks. When the rail transit screen door is unlocked and opened, the controller usually controls the electromagnet to drive the electromagnetic unlocking bracket to move after being energized, thereby driving the lock tongue transmission pin to move and release the restrictions on the left and right lock blocks. After power failure or power off, the automatic unlocking force will be lost, leaving a safety hazard.

[0005] The electromagnet itself has a high failure rate and a short lifespan. At the same time, the electromagnet is prone to jamming and burning under overheating conditions. In addition, the electromagnet will be affected by the current, further increasing the failure rate. Under low temperature conditions, there will be condensation (water droplets), which will also affect its service life.

[0006] In view of this, there is an urgent need to design a new locking device so as to overcome at least part of the above-mentioned defects of the existing locking devices. Summary of the invention

[0081] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0082] In order to further understand the present invention, preferred embodiments of the present invention are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0083] The description in this section is only for several typical embodiments, and the present invention is not limited to the scope of the embodiments. The same or similar prior art means and some technical features in the embodiments are mutually replaced within the scope of the present invention.

[0084] In the specification, some components have similar functions and use the same names and marks, but the specific structures of the components with the same names and marks may be different in different embodiments.

[0085] The present invention discloses a transmission mechanism, which includes a first component, a second component and a third component. The first component can be connected to a driving mechanism, and can move according to a set path under the drive of the driving mechanism; the action interval of the first component at least includes a first action interval and a second action interval. When the first component is in the first action interval, the second component does not follow the action of the first component; when the first component is in the second action interval, the second component performs a set action under the action of the first component. When the first component is in a set section of the first action interval (which can be a partial section or a full section), the third component can be connected to the first component, and the third component performs a set action under the action of the first component.

[0086] In one embodiment of the present invention, the first action interval and the second action interval are continuous, and the first action interval and the second action interval can be distinguished by whether the second component is subjected to sufficient force so that the second component can perform the set action.

[0087] In one embodiment of the present invention, the second component is provided with a limiting mechanism, so that the first component can move synchronously with the second component under the action of the limiting mechanism in the second action range.

[0088] In one embodiment of the present invention, the first component can perform linear motion under the drive of the driving mechanism.

[0089] Figure 1-1 is a schematic diagram of the structure of a transmission mechanism in one embodiment of the present invention; please refer to Figure 1-1In one embodiment of the present invention, the transmission mechanism includes a first component A, a second component B and a third component C. The first component A can be connected to a driving mechanism, and can move according to a set path under the drive of the driving mechanism; the action interval of the first component A at least includes a first action interval and a second action interval.

When the first component A is in the first action interval, the third component C can be connected to the first component A, and the third component C performs a set action under the action of the first component A.

[0090] The first action interval refers to the interval before the first component A applies sufficient force to the second component B to make the second component B move simultaneously with the first component A.

When the first rack 305 moves in the second action interval (the interval in which the second component B follows the first component A and starts to move in the direction of movement of the first component A), the first component A, the second component B and the third component C are driven together.

[0108] In an embodiment of the present invention, the second gear 307 may be connected to the lock body, and the second gear 307 may be rotated to achieve unlocking.

[0153] Figure 11-1 to Figure 11-3 is a schematic diagram of the structure of a driving device in one embodiment of the present invention; please refer to Figure 11-1 to Figure 11-3 In one embodiment of the present invention, the shielding door system (or other equipment) uses two power sources, and the driving device includes two driving motors 4 and corresponding synchronous belts 5. One driving motor 4 and synchronous belt 5 drive a door body to move; the synchronous belt 5 realizes transmission and unlocking through the transmission mechanism of the present invention.

[0154] In one embodiment, the left and right sides of the shield door system drive motors 4 and corresponding synchronous belts 5 (using two sets of power sources to act separately), and the drive motors 4 are connected to the corresponding door bodies through the corresponding synchronous belts 5 to drive the corresponding door body switches.

When the first component A is actuated, the third component C can be driven to act; the third component C is connected to the door lock, and the door lock is unlocked when the third component is actuated. After unlocking, the first component A continues to act. At this time, the second component B has not yet contacted the first component A, or the first component A cannot exert enough force on the second component B; at this time, the second component B does not follow the first component A to act, and the first component A and the second component B produce relative displacement.

[0157] In the second action interval of the first component A, the first component A contacts the second component B, or the first component A is connected to the second component B through a fourth component (such as an elastic component, which may be a spring, etc.); at this time, the second component B receives sufficient force applied by the first component A, so that it can follow the action of the first component A. The second component B is connected to the door body, and can drive the door body to open.

[0158] The structures of the two transmission mechanisms can be identical or partially identical, and the principle is to utilize the same power source (which can be the drive motor 4) to achieve unlocking and driving of the door body (unlocking first, then driving).

Fig.12 In one embodiment of the present invention, the transmission mechanism is longitudinally arranged (vertically arranged), and can also drive the load and unlock or lock the lock body through a driving device.

[0160] In one embodiment, the screen door system (which can also be used for other equipment) is a vertical lifting screen door system; the vertical lifting screen door system includes a driving motor 4, a belt 51, a traction wheel 16, a counterweight 17, a fixed pulley 18, a transmission mechanism, a door body 9 and a door lock.

The first end of the belt 51 is provided with a counterweight 17, and the second end of the belt 51 is connected to the transmission mechanism.

[0161] The belt 51 is arranged through the traction wheel 16 and the fixed pulley 18, and can move accordingly when the traction wheel 16 moves. Fig.12 As shown, in one embodiment, when the traction wheel 16 rotates clockwise, the belt 51 moves to Fig.12 The right side of the belt 51 moves in the middle, thereby driving the counterweight 17 to rise and drive the door body 9 to descend (action when closing the door); when the traction wheel 16 rotates counterclockwise, the belt 51 moves to the right side of the belt 51. Fig.12 The left side action in the middle drives the counterweight 17 to descend and can drive the door body 9 to rise (action when opening the door).

[0162] The transmission mechanism includes a first component A, a second component B and a third component C; the first component A is connected to the second component B and the third component C respectively, the second component B is connected to the door body 9, and the third component C is connected to the door lock. The belt 51 is connected to the first component A.

[0163] The following combination Fig.12 The specific process of the vertical lifting shielding door system during the door opening process is introduced. The driving motor 4 applies an upward pulling force to the transmission mechanism through the belt 51. The belt 51 is connected to the first component A, and the first component A is forced to move upward. In the first action interval of the first component A, the first component A is connected to the third component C. When the first component A moves, the third component C can be driven to move; the third component C is connected to the door lock, and the door lock is unlocked when the third component moves. After unlocking, the first component A continues to move. At this time, the second component B has not yet contacted the first component A, or the first component A cannot exert enough force on the second component B; at this time, the second component B does not follow the first component A to move, and the first component A and the second component B produce relative displacement.

[0164] In the second action interval of the first component A, the first component A contacts the second component B, or the first component A is connected to the second component B through a fourth component (such as an elastic component, which may be a spring, etc.); at this time, the second component B receives sufficient force from the first component A, so that it can move following the first component A. The second component B is connected to the door body 9, and can drive the door body 9 to move upward following the second component B, the first component A and the belt 51, so as to open the door.

[0165] In summary, the transmission mechanism proposed in the present invention can use the same driving source to drive at least two devices separately and in sections. In one use scenario of the present invention, the load driving source can be used to unlock the load, which improves the safety and reliability of the equipment while reducing costs. The existing load is usually driven by a load driving source, and the load is locked by an electromagnetic lock. The load needs to be unlocked by an electromagnet as a power source. Compared with the existing solution, the present invention can replace the electromagnetic lock with a mechanical locking device, and the driving source of the load first drives the transmission mechanism to complete the unlocking of the mechanical locking device, and then the driving source of the load drives the transmission mechanism and the load to act together, realizing that only the load driving source can be used to complete the process of unlocking the load and driving the load; the external driving source of the locking device is omitted.
