[0001] The present application relates to the field of rail transit, and in particular to a subway platform door with high safety performance. Background Art

[0002] With the acceleration of urbanization, the importance of subway as an efficient and environmentally friendly urban public transportation tool has become increasingly prominent. In order to ensure the safety of passengers, subway platform doors, also known as safety doors or safety barriers, need to be installed on subway platforms. They are located at the edge of the station platform and their main function is to isolate passengers from train tracks. They are vital safety facilities in the subway system.

[0003] At present, the existing subway platform doors usually adopt the left-right sliding opening and closing method. After the subway arrives at the station and stops steadily, the left and right door leaves of the subway platform door slide to both sides and open respectively, and passengers can pass through between the two door leaves. The left and right door leaves are closed before the subway is about to start. However, during peak hours or when there are hurried passengers, passengers are eager to get on the subway platform door while it is closing, which may easily lead to passengers being clamped by the subway platform door, thus posing a safety hazard. Summary of the invention

[0004] In order to improve the safety performance of subway platform doors, the present application provides a subway platform door with high safety performance.

[0005] The application provides a subway platform door with high safety performance adopts the following technical solution:

[0006] A subway platform door with high safety performance comprises a support frame, a sliding door, a driving mechanism and a control arm, wherein an entrance and an exit are provided on the support frame, and one sliding door is slidably provided on the support frame on both sides of the entrance and the exit, respectively; the driving mechanism is provided on the support frame and is used to drive the two sliding doors to move closer to or away from each other; one control arm is hingedly provided at the bottom of the side where the two sliding doors are close to each other, and the two ends of the two control arms away from the sliding doors are hinged to each other.

[0007] By adopting the above technical solution, when the driving mechanism drives the two sliding doors to approach each other and close the entrance and exit, the two sliding doors drive the two control arms to move, so that the control arms rotate in the direction of approaching the sliding doors, and then the two control arms can approach each other and intercept between the two sliding doors to block the passengers, and when the passengers are clamped by the two sliding doors, the hinges of the two control arms are pressed, so that the two control arms rotate in the direction away from the sliding doors, the two sliding doors can be propped open, and the clamped passengers can be rescued, effectively improving the safety performance of subway platform doors.

[0008] Optionally, the driving mechanism includes a driving motor, a supporting wheel and a belt, the driving motor is arranged on a supporting frame, the supporting wheel is rotatably arranged on the supporting frame, the belt is wound around the output shaft of the driving motor and the supporting wheel, and the two sliding doors are respectively connected to opposite sides of the wound belt.

[0009] By adopting the above technical solution, the drive motor is started, and the output shaft of the drive motor pulls the belt to rotate. The opposite sides of the belt can drive the two sliding doors to slide in opposite directions, thereby conveniently and quickly driving the two sliding doors away from or close to each other, and driving them by the same belt to improve the synchronization of the movement of the two sliding doors.

[0010] Optionally, the control arm is provided with a control mechanism for driving the two sliding doors away from each other, and the control mechanism includes a pressure sensor and a controller. The pressure sensor is arranged on the control arm, and the controller is arranged on the support frame and is electrically connected to the pressure sensor and the drive motor.

[0011] By adopting the above technical solution, after a clamping incident occurs, the staff presses the pressure sensor, and the pressure sensor sends an electrical signal to the controller. The controller can then control the drive motor so that the drive motor drives the belt to reverse and the two sliding doors move away from each other, thereby releasing the clamping of the passenger and facilitating rescue of the passenger.

[0012] Optionally, the control arm includes a control sleeve, a control rod and an elastic member, the control sleeve is hinged on the support frame, the pressure sensor is arranged on the inner bottom wall of the control sleeve, the control rod is slidably inserted on the inner wall of the control sleeve, the opening of the control sleeve is smaller than the cross-section of one end of the control rod located in the control sleeve, the control rod is hinged to the sliding door, and the elastic member is arranged on the inner bottom wall of the control sleeve and is used to drive the control rod away from the control sleeve.

[0013] By adopting the above technical solution, when the control rod is pressed to open the two sliding doors, the control rod squeezes the elastic member and slides toward the control sleeve. As the staff continues to press, the control rod abuts against the pressure sensor on the bottom wall of the control sleeve, reducing the possibility of the pressure sensor being accidentally touched and driving the two sliding doors to open.

[0014] Optionally, a receiving groove is provided on one side of the two sliding doors that are close to each other, and the receiving groove is used to accommodate the control sleeve and the control rod when the two sliding doors are in contact with each other.

[0016] Optionally, a telescopic rod is hingedly provided on one of the control sleeves, the telescopic rod is hingedly connected to the other control sleeve, and the length of the telescopic rod can be extended and retracted as the control sleeve rotates.

[0017] By adopting the above technical solution, as the control sleeve rotates with the movement of the sliding door, the length of the telescopic rod expands and contracts with the rotation of the control sleeve, and the telescopic rod continuously supports the control sleeve, thereby improving the stability of the control sleeve.

[0018] Optionally, one end of one of the control rods away from the control sleeve is hingedly provided with a pedal, and the other control rod is hingedly provided on the pedal.

[0019] By adopting the above technical solution, the staff can drive the two control rods away from each other by pressing or stepping on the pedal. The pedal increases the distance between the hinges of the two control rods, reducing the possibility of the staff being clamped by the two control rods when pressing or stepping on the control rods.

[0020] Optionally, a closing mechanism for closing the gap between the two sliding doors is provided on the support frame, and the closing mechanism includes a sliding rod, a protective net and a driving member. The sliding rod is slidably arranged on the support frame along the sliding direction of the sliding door, the protective net is arranged on the support frame and connected to the sliding rod, and the driving member is arranged on the support frame and is used to drive the sliding rod to slide.

[0021] By adopting the above technical solution, during the closing process of the two sliding doors, the driving member drives the sliding rod to slide from one sliding door to the direction close to the other sliding door, and the sliding rod drives the protective net to be pulled between the two sliding doors. The protective net can close the gap between the two sliding doors, thereby reducing the possibility of passengers passing through the two sliding doors and passing through the entrance and exit during the closing process of the sliding doors, thereby further improving safety.

[0022] Optionally, a closing plate is provided at the upper end of the support frame, and the closing plate seals the support frame and the top wall of the subway platform.

[0023] By adopting the above technical solution, the closing plate seals the support frame and the top wall of the subway platform, thereby improving the sealing inside and outside of the subway platform, reducing the noise transmitted into the subway platform when the subway is running, and reducing the loss of cooling or heating in the subway platform.

[0024] Optionally, an elastic plate is provided at the bottom of the sliding door, and the elastic plate is used to abut against the ground of the subway platform.

[0025] By adopting the above technical solution, the elastic plate seals the bottom of the sliding door and the ground of the subway platform, thereby improving the sealing between the sliding door and the ground of the subway platform and reducing the possibility of foreign matter entering the track through the gap between the sliding door and the subway platform.

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The embodiment of the present application discloses a subway platform door with high safety performance.

[0037] Reference Figure 1 , Figure 2The subway platform door with high safety performance includes a support frame 1, a sliding door 2, a driving mechanism 3, a control arm 4 and a closing mechanism 8.

[0038] Reference Figure 1 The support frame 1 is installed at the edge of the subway platform. In this embodiment, the support frame 1 includes a plurality of columns and a plurality of glass plates. The plurality of columns are installed at intervals along the edge of the subway platform by bolts, and the glass plates are installed between adjacent columns, wherein a hollow space is formed between two columns to form an entrance and exit 11 for passengers to enter and exit; a closing plate 9 is installed at the upper end of the support frame 1, and the closing plate 9 seals the gap between the support frame 1 and the top wall of the subway platform.

[0039] The support frame 1 and the closing plate 9 cooperate to separate the subway platform from the track, improve the sealing inside and outside of the subway platform, reduce the noise transmitted into the subway platform when the subway is running, improve the comfort of passengers in the subway platform, and reduce the loss of cold air or hot air in the subway platform to the track side, reduce the power consumption of the air-conditioning system in the subway platform, and facilitate the control of the temperature in the subway platform.

[0040] Reference Figure 1 , Figure 2 The sliding door 2 is slidably mounted on the support frame 1 on the left and right sides of the entrance and exit 11. In this embodiment, the support frame 1 is installed with guide rails on both the upper and lower sides of the entrance and exit 11. The upper and lower ends of the sliding door 2 slide on the two guide rails respectively to improve the stability of the sliding door 2 during sliding. The bottom of the sliding door 2 is installed with an elastic plate 10. In this embodiment, the elastic plate 10 is a corrugated plate, which is stretched by bolts and abuts on the ground of the subway platform, so that the elastic plate 10 can be suitable for different distances between the sliding door 2 and the ground. The gap between the bottom of the sliding door 2 and the ground of the subway platform is closed by the elastic plate 10, which improves the sealing between the sliding door 2 and the ground of the subway platform and reduces the possibility of foreign matter entering the track from the gap between the sliding door 2 and the subway platform.

[0041] Reference Figure 2The driving mechanism 3 is installed on the support frame 1, and the driving mechanism 3 is used to drive the two sliding doors 2 to move closer to or away from each other. The driving mechanism 3 includes a driving motor 31, a supporting wheel 32 and a belt 33. The driving motor 31 is installed on the support frame 1. In this embodiment, the driving motor 31 is a servo motor, an auxiliary wheel is installed on the support frame 1, and an adjusting seat is slidably installed on the support frame 1 along the sliding direction of the sliding door 2. A screw is installed on the support frame 1, and the screw is threadedly connected to the adjusting seat. The supporting wheel 32 is rotatably installed on the adjusting seat. The belt 33 is a toothed chain, which is wound around the auxiliary wheel and the belt 33. The staff rotates the screw to adjust the supporting wheel 32 away from or close to the auxiliary wheel, thereby conveniently and quickly adjusting the tension of the belt 33; the toothed chain is meshed with the output shaft of the driving motor 31 through gears, one of the sliding doors 2 is connected to the belt body on the lower side of the circumferentially wound belt 33, and the other sliding door 2 is connected to the upper side of the circumferentially wound belt 33.

[0042] Start the drive motor 31, and the output shaft of the drive motor 31 drives the belt 33 to rotate. The lower belt body and the upper belt body of the wound belt 33 can respectively drive the two sliding doors 2 to slide in opposite directions, so that the two sliding doors 2 are moved closer to each other to close or away from each other to open, thereby realizing the opening and closing of the entrance 11. The drive motor 31 drives one belt 33 to drive the two sliding doors 2, and the two sliding doors 2 have good synchronization in movement.

[0043] Reference Figure 2 , Figure 3 , control arms 4 are hingedly installed on both sliding doors 2, and the control arms 4 include a control sleeve 41, a control rod 42 and an elastic member 43. The control sleeve 41 is hingedly installed at the bottom position of the sliding door 2 on one side close to the adjacent sliding door 2. The control sleeve 41 is hollow inside and has an opening at one end away from the sliding door 2. The control rod 42 is slidably inserted on the inner wall of the control sleeve 41 along the length direction of the control sleeve 41. The opening size of the control sleeve 41 is smaller than the internal opening size of the control sleeve 41. The cross-sectional size of one end of the control rod 42 sliding in the control sleeve 41 is larger than the opening size of the control sleeve 41. The elastic member 43 is installed on the inner bottom wall of the control sleeve 41. The elastic member 43 is used to drive the control rod 42 away from the control sleeve 41. In this embodiment, the elastic member 43 is a spring, one end of the spring is installed on the inner bottom wall of the control sleeve 41, and the other end of the spring is installed on the control rod 42. The spring always has a tendency to drive the control rod 42 away from the control sleeve 41.

[0044] Reference Figure 2 , Figure 3 One end of one control rod 42 away from the sliding door 2 is hingedly mounted with a pedal 7, and the other end of the other control rod 42 away from the sliding door 2 is hingedly mounted on the pedal 7.

[0045] During the opening of the two sliding doors 2, the sliding doors 2 pull the control sleeve 41, so that the control sleeve 41 rotates in the direction away from the sliding doors 2, so that the two control rods 42 move away from each other and unfold. After the two doors open and the entrance 11 is fully opened, the two control arms 4 unfold to a horizontal state and are stored in the subway platform floor, so that passengers can enter and exit the entrance 11 normally; during the closing of the two sliding doors 2, the sliding doors 2 squeeze the control sleeve 41, and the control sleeve 41 squeezes the control rod 42 through the elastic member 43, so that the two control rods 42 approach each other. During the process of the two control rods 42 approaching each other, they move upward and are intercepted between the two sliding doors 2. The pedal 7 can also facilitate the staff to drive the two control rods 42 away from each other, and at the same time increase the spacing between the hinges of the two control rods 42 and block the hinges of the two control rods 42, thereby reducing the possibility of the staff being clamped by the two control rods 42 when pressing or stepping on the control arms 4.

[0046] Reference Figure 2 , the two sliding doors 2 are provided with a receiving groove 21, which is located on the side of the sliding door 2 close to the adjacent sliding door 2, and the receiving groove 21 is used for receiving the control sleeve 41 and the control rod 42 when the two sliding doors 2 are closed. When the two sliding doors 2 are closed, the two control sleeves 41 and the control rod 42 are respectively rotated in the direction close to the sliding door 2, and the control sleeve 41 and the control rod 42 can be received in the receiving groove 21, so that the two sliding doors 2 can abut against each other to close the inlet and outlet 11, effectively reducing the influence of the control sleeve 41 and the control rod 42 on the airtightness of the two sliding doors 2 when they are closed, and improving the tightness of the closing of the two sliding doors 2.

[0047] Reference Figure 2 , Figure 3 A telescopic rod 6 is hingedly installed on one of the control sleeves 41, and the length of the telescopic rod 6 can be extended and retracted as the control sleeve 41 rotates. In the present embodiment, the telescopic rod 6 is composed of a plurality of sleeve rods, each of which is hollow inside and open at one end. The internal opening diameter of each sleeve rod decreases successively, so that the plurality of sleeve rods can be inserted in sequence into the sleeve rod with a larger inner diameter opening, so that the length of the telescopic rod 6 after being fully retracted is less than the distance between the hinge points of the two control rods 42 on the pedal 7. When the two sliding doors 2 are closed, the telescopic rod 6 can be stored in the accommodating groove 21 together to ensure that the two sliding doors 2 can be closed.

[0048] The telescopic rod 6 includes a support sleeve and a support rod. The support sleeve is hingedly mounted on one of the control sleeves 41. The interior of the support sleeve is hollow and one end away from the control sleeve 41 is open. The support rod is slidably mounted on the inner wall of the support sleeve. The end of the support rod away from the support sleeve is hinged to the other control sleeve 41.

[0049] When the two sliding doors 2 are opened, the sliding doors 2 drive the two control sleeves 41 to move away from each other, and the two control sleeves 41 pull the telescopic rod 6 to extend. When the two sliding doors 2 are closed, the sliding doors 2 drive the two control sleeves 41 to move closer to each other, and the two control sleeves 41 compress the telescopic rod 6 to shorten the telescopic rod 6, thereby achieving the telescopic rod 6 to adaptively extend and retract as the two control sleeves 41 rotate, and the telescopic rod 6 can continuously extend and retract the control sleeve 41 during the extension and retraction process of the sliding door 2, thereby improving the stability of the control sleeve 41 in a direction perpendicular to the opening and closing direction of the sliding door 2.

[0050] Reference Figure 3 A control mechanism 5 is installed on the control sleeve 41. The control mechanism 5 is used to drive the two sliding doors 2 away from each other. The control mechanism 5 includes a pressure sensor 51 and a controller 52. The pressure sensor 51 is installed on the inner bottom wall of the control sleeve 41. The controller 52 is installed on the control sleeve 41. The controller 52 is electrically connected to the pressure sensor 51, and the controller 52 is electrically connected to the driving motor 31.

[0051] When the passenger is trapped and presses or steps on the pedal 7 to open the two sliding doors 2, the control rod 42 squeezes the elastic member 43 under the action of pressing or stepping and moves in the direction close to the control sleeve 41. As the staff continues to press, the control rod 42 can abut against the pressure sensor 51 on the inner bottom wall of the control sleeve 41. The pressure sensor 51 sends an electrical signal to the controller 52. The controller 52 controls the output shaft of the drive motor 31 to drive the two sliding doors 2 to rotate away from each other, so that the two sliding doors 2 are opened and the passengers are released, which is convenient for rescuing the trapped passengers. In addition, the elastic member 43 supports the control rod 42, so that the control rod 42 can abut against the pressure sensor 51 only when the staff presses hard, reducing the possibility of the pressure sensor 51 being accidentally touched and driving the two sliding doors 2 to open, thereby improving the stability of the two sliding doors 2 closing and sealing the entrance and exit 11.

[0052] Reference Figure 2 , Figure 4, the closing mechanism 8 is installed on the support frame 1, and the closing mechanism 8 is used to close the gap between the two sliding doors 2. The closing mechanism 8 includes a sliding rod 81, a protective net 82 and a driving member 83. The sliding rod 81 is slidably installed on the support frame 1 along the sliding direction of the sliding door 2, one end of the protective net 82 is installed on the support frame 1, and the other end of the protective net 82 is installed on the sliding rod 81. In this embodiment, the protective net 82 is a nylon net; the driving member 83 is installed on the support frame 1, and the driving member 83 is used to drive the sliding rod 81 to slide. In this embodiment, the driving member 83 includes a servo motor and a screw rod. The servo motor is installed on the support frame 1, and the screw rod is rotatably installed on the support frame 1 along the sliding direction of the sliding door 2. The screw rod is coaxially connected to the output shaft of the servo motor, and the screw rod is threaded on the sliding rod 81.

[0053] When the two sliding doors 2 approach each other and close the entrance 11, the servo motor starts, and the output shaft of the servo motor drives the screw to rotate, and the screw drives the sliding rod 81 to slide from the side of the entrance 11 close to the protective net 82 toward the other side of the entrance 11. During the sliding process of the sliding rod 81, the protective net 82 is pulled, so that the protective net 82 is pulled from one side of the entrance 11 to the other side. The protective net 82 can close the entrance 11, and then close the gap between the two sliding doors 2 during the closing process, reducing the possibility of passengers passing through the two sliding doors 2 and passing through the entrance 11 during the closing process of the sliding door 2, thereby further improving safety.

[0054] The implementation principle of a subway platform door with high safety performance in the embodiment of the present application is as follows: when the driving motor 31 is started and drives the two sliding doors 2 to approach each other to close the entrance and exit 11, the driving member 83 drives the sliding rod 81 to drive the protective net 82 to close the entrance and exit 11. At the same time, when the two sliding doors 2 are approaching each other, the sliding doors 2 pull the two control arms 4 to approach each other and block between the two sliding doors 2. Through the double blocking of the protective net 82 and the two control arms 4, the possibility of passengers passing through the entrance and exit 11 during the closing process of the sliding doors 2 is effectively reduced. If the passenger is clamped by the two sliding doors 2, the staff can also press or step on the pedal 7, so that the pressure sensor 51 sends an electrical signal to the controller 52 after being compressed. The controller 52 controls the driving motor 31 to drive the two sliding doors 2 away from each other and release the passenger. After release, the protective net 82 still blocks the two entrances and exits 11. Even if the pressure sensor 51 or the controller 52 is damaged, the staff can press or step on the pedal 7 to prop open the two sliding doors 2 through the two control arms 4 to rescue the passenger, thereby jointly improving the safety performance of the subway platform door.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
