Description

Technical Field

[0001] The present invention belongs to the technical field of rail transportation, and in particular relates to an electromagnetic lifting platform door system applicable to multiple types of vehicles. Background Art

[0002] With the rapid development of social economy and domestic cities, the scale of cities and the flow of people between cities have become more intensive. Rail transit, as one of the key ways to connect cities and the passage of people within cities, has also grown rapidly in recent years with the emergence of people's travel needs, showing a relatively high enthusiasm for research and development, which in turn has prompted rail transit related technologies to show a trend of rapid development.

[0003] With the increasing popularity of mixed operation of various rail transit modes such as urban rail transit, high-speed rail transit, and intercity rail transit, in order to reduce the scale of stations, it is usually necessary to simultaneously accommodate the docking of different types of standard vehicles on the same station platform. However, since the number, position, and opening degree of doors of different standard vehicles are different, the sliding platform doors on the platform cannot correspond to the doors of various types of standard vehicles, affecting the normal boarding and alighting of passengers.

[0004] At the same time, the vast majority of high-speed rail platforms currently lack platform doors. On-site staff urge passengers to stay within the safety line, but this clearly fails to fundamentally address passenger and public safety concerns. Installing platform doors would not only fail to accurately align doors with multiple train types, but would also occupy a significant portion of platform space, increasing costs. Furthermore, because existing platform doors typically utilize mechanical transmission mechanisms, the transitional movement of the doors often produces noise, impacting the passenger experience. Summary of the Invention

[0005] In response to one or more of the above-mentioned defects or improvement needs in the prior art, the present invention provides an electromagnetic lifting platform door system suitable for multiple types of vehicles, which can adapt to the docking of vehicles of different standards, so that the platform door can accurately correspond to doors of different positions and openings, reduce the space occupied by the platform door, reduce the noise generated by the platform door during movement, and avoid affecting passengers waiting for the train on the platform.

[0006] To achieve the above-mentioned object, the present invention provides an electromagnetic lift platform door system applicable to multiple types of vehicles, comprising a control module, two vertically extending columns spaced apart on the platform, and a door leaf disposed between the two columns;

[0016] As a further preferred embodiment of the present invention, at least one locking mechanism is provided between the column and the door leaf for positioning the door leaf on the column.

[0017] As a further preferred embodiment of the present invention, the locking mechanism includes a plurality of pin holes arranged on the column at vertical intervals and corresponding automatic telescopic latches arranged on the door leaf.

[0018] As a further preferred embodiment of the present invention, at least one counterweight mechanism is provided between each of the upright columns and the door leaf.

[0019] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0020] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:

[0021] (1) The present invention provides an electromagnetic lift platform door system suitable for multiple types of vehicles. It arranges two vertically extending column structures at intervals on the platform, so that the doors carried by the carriages of different types of vehicles to be parked in this area can all fall between the two columns. At the same time, by arranging the door leaf between the two columns and the electromagnetic drive mechanism between the door leaf and each column, the electromagnetic drive mechanism drives the door leaf to reciprocate in the vertical direction, thereby enabling the electromagnetic lift platform door to minimize the occupation of the platform space on the basis of being able to achieve controllable blocking of the space between the columns. At the same time, the electromagnetic drive method is used to drive the door leaf to reciprocate vertically, which can reduce the noise during the operation of the door leaf and improve the comfort of passengers waiting for the bus. And by arranging a control module that is in communication with the electromagnetic drive mechanism, the controllability of the vertical movement of the door leaf is effectively improved.

[0022] (2) The electromagnetic lifting platform door system of the present invention is applicable to multiple types of vehicles. It ensures stable guidance of the door leaf during vertical movement by opening a U-shaped groove on the column or setting a U-shaped groove on the door leaf, and setting a guide magnet and an induction body based on the groove structure, thereby avoiding contact between the door leaf and the column during actual movement, and providing effective protection for passenger safety and equipment safety.

[0023] (3) The electromagnetic lifting platform door system of the present invention is suitable for multiple types of vehicles. It realizes real-time and accurate positioning of the door leaf position, posture and speed by respectively arranging a plurality of first detection components, second detection components and third detection components on the electromagnetic driving mechanism, the guide mechanism and the top or bottom of the column, thereby improving the controllability and accuracy of the electromagnetic lifting platform door system.

[0024] (4) The electromagnetic lifting platform door system of the present invention is applicable to multiple types of vehicles. It is provided with a locking mechanism composed of an electromagnetic spring latch and a pin hole. It can not only realize the active positioning of the door leaf after it moves to the specified position, but also can realize the structural design of the electromagnetic combined with the spring. In the case of a sudden power outage, the locking mechanism can quickly lock the door leaf on the column, further providing effective protection for the safety of passengers and equipment.

[0025] (5) The electromagnetic lifting platform door system of the present invention is suitable for multiple types of vehicles. It sets a counterweight mechanism including a pulley, a connecting rope and a counterweight block. The pulley is set at the top of the column, and the connecting rope is wrapped around the pulley. At the same time, the counterweight block and the door leaf are connected at both ends respectively, so as to prevent the door leaf from sliding down in the case of sudden power failure, thereby providing effective protection for passenger safety and equipment safety.

[0026] (6) The electromagnetic lifting platform door system of the present invention is suitable for multiple types of vehicles. It has a simple structure, stable operation and high reliability. By setting columns arranged at intervals on the platform and door leaves arranged between the columns, when vehicles of different standards stop, the doors of different carriages at the same position can be correspondingly positioned between the two columns, so that the doors can be controlled and blocked by the door leaves. By using columns or door leaves with U-shaped groove structures and permanent magnets or linear motors arranged on the door leaves and columns to drive the door leaves to move back and forth in the vertical direction, the platform door can be arranged along the edge of the platform, reducing the space occupied by the electromagnetic lifting platform door system and reducing the operating noise of the lifting platform door. In addition, by correspondingly setting the inductor and guide magnet on the door leaf and the column, reliable guidance of the vertical reciprocating movement of the door leaf is achieved. Combined with the first detection component, the second detection component and the third component arranged on the door leaf and / or the column, the movement, position and posture of the door leaf are detected in real time, thereby improving the safety and reliability of the door leaf movement. In addition, through the configuration mechanism set between the door leaf and the column and the locking mechanism including the electromagnetic spring latch, the positioning and power-off protection of the door leaf are achieved, thereby providing effective protection for passenger safety and equipment safety, with excellent economic benefits and promotion value.

[0037] Example:

[0038] like Figures 1 to 3 As shown in the , an electromagnetic lifting platform door system suitable for multiple types of vehicles in a preferred embodiment of the present application can adapt to the docking of vehicles of different standards, so that the platform door can accurately correspond to doors of different positions and openings, reduce the platform space occupied by the platform door, reduce the noise generated by the platform door during movement, and avoid affecting passengers waiting for the bus on the platform.

[0039] Specifically, if Figure 1 As shown in the , in a preferred embodiment of the present application, the electromagnetic lift platform door system includes two vertically extending columns 1 spaced apart on the platform, a door leaf 2 disposed between the two columns 1, and a control module. The columns 1 serve as the support structure for the lift platform door. To ensure that vehicle doors of different standards can be accommodated on the lift platform door, the spacing between the two columns 1 is greater than the width of the doors of different standards. That is, the projection of a door of a compartment of any standard vehicle in the front (lateral) direction can fall between the two columns 1, thereby meeting the parking requirements of vehicles of different standards. The door leaf 2 is arranged longitudinally between the two columns 1, and its two ends cooperate with the corresponding columns 1 respectively, and an electromagnetic drive mechanism is arranged between each column 1 and the end of the door leaf 2, and the electromagnetic drive mechanism drives the door leaf 2 to move in the vertical direction, that is, after the vehicle is stably parked, the electromagnetic drive mechanism drives the door leaf 2 to rise vertically, thereby opening the passage connecting the platform and the car, making it convenient for passengers to get on and off the vehicle; and after the vehicle door is closed, the electromagnetic drive mechanism drives the door leaf 2 to move downward, thereby blocking the passage between the platform and the car, preventing passengers from entering the track area. In addition, the electromagnetic drive mechanism is communicatively connected to the control module, and the control module controls the door leaf 2 to reciprocate in the vertical direction. It should be noted that the extension direction along the vehicle and the track is the longitudinal direction, the direction perpendicular to the longitudinal direction in the horizontal plane is the transverse direction, and the direction perpendicular to the horizontal plane is the vertical direction.

[0040] Furthermore, in a preferred embodiment of the present application, the electromagnetic drive mechanism includes a linear motor 6 extending vertically and arranged on the column 1. Correspondingly, a permanent magnet 7 or an electromagnet extending vertically is correspondingly arranged on the door leaf 2. In actual use, the electromagnetic field generated by the linear motor 6 is regulated to achieve stable control of the movement of the door leaf 2. Preferably, in order to achieve stable drive of the permanent magnet 7 on the door leaf 2 by the linear motor 6, the permanent magnet 7 or the electromagnet is arranged on the side wall surfaces at both longitudinal ends of the door leaf 2. Correspondingly, the linear motor 6 is arranged on the end surface of the column 1 corresponding to the permanent magnet 7, thereby ensuring that the door leaf 2 is subjected to a balanced driving force by acting on both ends of the door leaf 2 at the same time.

[0041] Further preferably, in order to ensure the stability of the door leaf 2 during the vertical movement driven by the linear motor 6, in the preferred embodiment of the present application, a plurality of first detection components 8 are provided on the end face of the column 1 where the linear motor 6 is installed or the end face of the door leaf 2 where the permanent magnet 7 is installed, for detecting the longitudinal spacing between the door leaf 2 and the column 1, thereby preventing the door leaf 2 from contacting the column 1 during the vertical movement. Preferably, at least two first detection components 8 are provided at vertical intervals on the side walls at both longitudinal ends of the door leaf 2, so as to determine whether the longitudinal side walls of the door leaf 2 are parallel to the longitudinal side walls of the column 1. Of course, a plurality of first detection components 8 can also be provided at vertical intervals on the longitudinal side walls of the column 1, and the vertical spacing distance between two adjacent first detection components 8 is smaller than the vertical dimension of the door leaf 2, so that the first detection components 8 can accurately detect the positional relationship between the door leaf 2 and the column 1 and the posture of the door leaf 2. Preferably, the first detection component 8 is a laser ranging sensor.

[0042] Further, if Figure 2 As shown, in a preferred embodiment of the present application, both columns 1 have vertically extending U-shaped slots, and the slots of the U-shaped slots on the two columns 1 face each other. The door leaf 2 is a plate-like structure, and the linear motor 6 is fixedly mounted on the vertically arranged bottom of the U-shaped slots of the column 1. Correspondingly, the permanent magnets 7 are arranged on the longitudinal side walls of the plate-like structure. In actual use, the door leaf 2 is embedded in the U-shaped slots of the column 1, so that the permanent magnets 7 can correspond to the linear motors 6, thereby ensuring that the door leaf 2 can reciprocate vertically.

[0043] Of course, the door leaf 2 and the column 1 are not limited to the above-described forms. In another preferred embodiment of the present application, the door leaf 2 is a plate-like structure extending longitudinally, and a U-shaped groove for the door leaf 2 extending vertically is provided at both longitudinal ends of the plate-like structure. Accordingly, the column 1 adopts a plate-like structure or is provided with a vertically extending support plate capable of being embedded in the U-shaped groove of the door leaf 2. During actual installation, the linear motor 6 is provided on the side wall surface of the support plate opposite to the door leaf 2, while the permanent magnet 7 is fixedly mounted on the bottom surface of the U-shaped groove of the door leaf 2. During actual use, the support plate on the column 1 is embedded in the U-shaped groove of the door leaf 2, so that the permanent magnet 7 and the linear motor 6 correspond to each other, thereby ensuring that the door leaf 2 can reciprocate vertically.

[0044] Further preferably, in the preferred embodiment of the present application, an electromagnetic guide mechanism extending vertically is provided between the column 1 and the door leaf 2, for guiding the door leaf 2 in vertical reciprocating motion, thereby ensuring the stability of the movement of the door leaf 2. Preferably, the electromagnetic guide mechanism includes two guide magnets 9 and two inductors, the two guide magnets 9 being symmetrically arranged on the groove wall surface of the U-shaped groove of the column 1, and the guide magnets 9 extending vertically. Accordingly, two inductors are also symmetrically arranged on the two side walls of the door leaf 2 along the horizontal direction, corresponding to the groove wall surface of the U-shaped groove of the column 1. Through the interaction between the inductors and the guide magnets 9, the movement guidance of the door leaf 2 is effectively achieved. Preferably, the inductors are also arranged vertically to ensure the stability of the interaction between the inductors and the guide magnets 9. Further preferably, the guide magnet 9 includes a plurality of electromagnets arranged at intervals along the vertical direction.

[0045] Of course, the electromagnetic guiding mechanism is not limited to the above-mentioned arrangement. In another preferred embodiment of the present application, two guiding magnets 9 are symmetrically arranged on the groove wall surface of the U-shaped groove of the door leaf 2, and the guiding magnets 9 extend vertically. Accordingly, on the two side walls of the column 1 along the horizontal direction, two induction bodies are also symmetrically arranged on the groove wall surface corresponding to the U-shaped groove of the door leaf 2. Through the interaction between the induction body and the guiding magnet 9, the movement guidance of the door leaf 2 is effectively realized.

[0046] Furthermore, in a preferred embodiment of the present application, the door leaf 2 is made of carbon fiber, and a metal induction body is provided at the position of the door leaf 2 corresponding to the guide magnet 9. Alternatively, the door leaf 2 is made of a light alloy, and the guide magnet 9 is directly provided through the entire door body.

[0047] In more detail, in a preferred embodiment of the present application, a plurality of second detection members 10 spaced apart in the longitudinal direction are provided on at least one column 1 to detect the position of the door leaf 2 when it reciprocates on the column 1. Preferably, the second detection member 10 is provided on the end face where the guide magnet 9 is provided. For example, a plurality of second detection members 10 are symmetrically arranged on both wall surfaces of the U-shaped groove of the column 1, and the vertical distance between two adjacent second detection members 10 is less than the vertical width of the door leaf 2. Thus, the posture of the door leaf 2 can be accurately judged by the detection results of the two adjacent second detection members 10. Of course, at least two second detection members 10 can also be provided on each of the two end faces of the door leaf 2 opposite to the guide magnet 9, and the judgment of the posture of the door leaf 2 can also be achieved. Preferably, the second detection member 10 is a laser ranging sensor.

[0048] Furthermore, in a preferred embodiment of the present application, in order to accurately monitor the vertical position and movement speed of the door leaf 2, a third detection member is provided at the top or bottom end of the column 1 facing the door leaf 2. Preferably, the third detection member is provided directly above or below the door leaf 2, and the third detection member is also preferably a laser ranging sensor, thereby achieving accurate detection of the vertical position and running speed of the door leaf 2.

[0049] Further preferably, in a preferred embodiment of the present application, at least one locking mechanism is provided between the column 1 and the door leaf 2, for locking and connecting the door leaf 2 and the column 1 after the door leaf 2 reaches a designated position. Preferably, the locking mechanism includes a plurality of pin holes 5 arranged on the column 1 at vertical intervals and an automatic telescopic latch provided on the door leaf 2 to correspond to the pin holes 5. During actual use, after the door leaf 2 moves to the designated position, the telescopic end of the automatic telescopic latch extends and embeds into the corresponding pin hole 5, thereby achieving stable fixation of the door leaf 2. Preferably, two automatic telescopic latches spaced vertically are provided at both longitudinal ends of the door leaf 2 to facilitate improving the stability of the positioning of the door leaf 2. Further preferably, as Figure 1 As shown in the figure, a U-shaped groove of the column 1 is provided on the column 1, and blind holes or pin holes 5 that pass through the groove wall are provided laterally on the groove walls on both sides of the U-shaped groove of the column 1. Accordingly, the telescopic direction of the automatic telescopic pin provided on the door leaf 2 is horizontal telescopic, so as to ensure that the locking mechanism can stably fix the door leaf 2 on the column 1.

[0050] More specifically, in a preferred embodiment of the present application, to prevent the door leaf 2 from falling due to power outages, the automatically retractable latch is an electromagnetic spring latch. This latch retracts by providing an electromagnetic unit that attracts the latch and compresses a spring. When the electromagnetic spring latch needs to be extended, the electromagnet is de-energized, and the latch, under the action of the spring, extends and enters the pin hole 5, securing the door leaf 2. In a power-off state, the electromagnetic spring latch extends simultaneously, allowing the door leaf 2 to enter the pin hole 5 during a relatively small drop, thus preventing the door leaf 2 from falling and posing a threat to passenger safety.

[0051] Of course, the power-off protection of the door leaf 2 is not limited to the above-mentioned technical solution. In the preferred embodiment of the present application, at least one counterweight mechanism is provided between each column 1 and the door leaf 2 to prevent the door leaf 2 from sliding after power failure.

[0052] Preferably, the counterweight mechanism comprises a pulley mounted on top of column 1, a connecting cable, and a counterweight. The connecting cable passes over the pulley, with its ends fixedly connected to the control block and door leaf 2, respectively. In the event of a power outage, the counterweight, via the connecting cable, holds door leaf 2 in place, preventing it from falling and ensuring safe waiting for passengers. Furthermore, preferably, the length of the connecting cable is equal to the vertical distance between the pulley and the top surface of the platform.

[0053] Furthermore, in a preferred embodiment of the present application, a crossbeam is disposed between the tops of the two uprights 1, thereby forming a door-like structure. Preferably, at least one car display 4 is disposed on the crossbeam to display information about the car corresponding to the electromagnetic lift platform door. Further preferably, at least one train number display 3 is disposed on the uprights 1 to display information about the train to be docked.

[0054] Furthermore, in a preferred embodiment of the present application, the electromagnetic lift platform door is further provided with a fourth detection component and a warning component. The fourth detection component is preferably an image recognition camera, which is used to capture and identify the position of waiting passengers and determine whether the passengers are too close to the door leaf 2. If a passenger is too close to the door leaf 2, the warning component warns the passenger to stay away. Preferably, the warning component is a speaker.

[0055] Preferably, the first detection member 8 , the second detection member 10 , the third detection member, the fourth detection member, and the electromagnetic guide mechanism are all communicatively connected to the control module.

[0056] Furthermore, in a preferred embodiment of the present application, the electromagnetic guide mechanism and the electromagnetic drive mechanism are both provided with corresponding backup power supplies to ensure stable power supply to both in the power-off state, thereby preventing the door leaf 2 from falling suddenly.

[0057] Furthermore, in a preferred embodiment of the present application, the working process of the electromagnetic lift platform door system applicable to multiple vehicle types is as follows:

[0058] S1. The control module receives the door opening command after the vehicle stops and generates an ascending control command;

[0059] S2, the control module transmits the ascending control instruction to the linear motor 6 and the guide magnet 9;

[0060] S3, the linear motor 6 generates a changing magnetic field according to the rising control instruction, driving the door leaf 2 to rise, and the guide magnet 9 generates a guide magnetic field according to the rising control instruction;

[0061] S4, the second detection component 10 detects the position of the door leaf 2 in real time until the door leaf 2 rises to the specified position, and sends the detection parameters to the control module;

[0062] S5, the control module generates a stop instruction according to the detection parameters and sends it to the linear motor 6 and the locking mechanism;

[0063] S6: The linear motor 6 stops generating the changing magnetic field according to the stop command, and the locking mechanism locks the door leaf 2 and the pillar;

[0064] S7: The control module receives the door closing instruction after the passengers have completed boarding and disembarking, and generates a descent control instruction;

[0065] S8, the control module transmits the descending control instruction to the linear motor 6 and the guide magnet 9;

[0066] S9, the linear motor 6 generates a changing magnetic field according to the descending control instruction, driving the door leaf 2 to descend, and the guide magnet 9 generates a guide magnetic field according to the descending control instruction;

[0067] S10, the second detection component 10 detects the position of the door leaf 2 in real time until the door leaf 2 drops to the specified position, and sends the detection parameters to the control module;

[0068] S11, the control module generates a stop instruction according to the detection parameters and sends it to the linear motor 6 and the locking mechanism;

[0069] S12: The linear motor 6 stops generating the changing magnetic field according to the stop instruction, and the locking mechanism locks the door leaf 2 and the pillar.

[0070] The electromagnetic lift platform door system of the present invention is suitable for multiple vehicle types and has a simple structure, stable operation, and high reliability. By providing columns 1 spaced apart on the platform and door panels 2 disposed between the columns 1, the system allows the doors of different carriages at the same location to be positioned between the two columns 1 when corresponding vehicles of different standards are docked, thereby enabling controllable blocking of the doors by the door panels 2. By employing columns 1 or door panels 2 with U-shaped groove structures and permanent magnets 7 or linear motors 6 disposed on the door panels 2 and columns 1 to drive the door panels 2 in vertical reciprocating motion, the platform door can be positioned along the edge of the platform, reducing the space occupied by the electromagnetic lift platform door system and lowering the operating noise of the lift platform door. Furthermore, by correspondingly setting the induction body and guide magnet 9 on the door leaf 2 and the column 1, reliable guidance of the vertical reciprocating motion of the door leaf 2 is achieved. Combined with the first detection member 8, the second detection member 10, and the third member set on the door leaf 2 and / or the column 1, the movement, position, and posture of the door leaf 2 are detected in real time, thereby improving the safety and reliability of the movement of the door leaf 2. In addition, by setting the configuration mechanism between the door leaf 2 and the column 1 and the locking mechanism including the electromagnetic spring latch, the positioning and power-off protection of the door leaf 2 are achieved, thereby providing effective protection for the safety of passengers and equipment, and having excellent economic benefits and promotion value.
