Hereinafter, with reference to the accompanying drawings will be described in detail the safety device of the electric vehicle platform according to an embodiment of the present invention.

1 is a view showing an installation state of a safety device according to an embodiment of the present invention.

As shown in the drawing, a plurality of protective walls 10 are continuously provided in the boarding point 200 of the electric vehicle 100 and have a transparent window 11 formed at a center thereof at predetermined intervals. And, the landing board 200 between any one of the protective wall (10a) and the other protective wall (10b) is provided with a case (60) with a built-in sliding footrest 70 (see Fig. 4). At this time, the distance D between any one of the guard walls 10a adjacent to each other and the other guard wall 10b is equal to the width of the doorway 101 (see FIG. 6B) of the electric vehicle 100. The footrest 70 compensates for the gap between the electric vehicle 100 and the boarding point 200 while moving in and out of the case 60.

A protective wall 10 and a plurality of components installed in the protective wall 10 according to the present embodiment will be described with reference to FIGS. 1 and 2. 2 is a perspective view of a protective wall according to an embodiment of the present invention.

As shown, a pair of automatic doors 20 are slidably installed horizontally on the rear surface of the protective wall 10. More specifically, any one automatic door 21a is provided on one side of the side of the protective wall 10, and the other automatic door 21b is provided on the other side of the side. One automatic door 21a and the other automatic door 21b move horizontally in the form of getting closer and farther from each other.

Then, as shown in Fig. 1, any one automatic door 21a installed on one of the adjacent protective walls 10a and one automatic door 23a provided on the other protective wall 10b are close to each other. As it moves away, the gap between one of the protective walls 10a and the other of the protective walls 10b is opened and closed. Then, the other automatic door 21b installed on one of the protective walls 10a and the one automatic door 25a installed on the other protective wall 10c are closer to each other and move away from each other. The gap between the other protective wall 10c is opened and closed.

The lower side of the protective wall 10 is provided with a first drive unit 30 for sliding the automatic door 20 to open and close between the adjacent protective wall 10. The first drive unit 30 has a first housing 31, a first piston 33 and a chain 35.

The first housing 31 is installed on the rear surface of the protective wall 10 to form a predetermined sealed space. One end side of the first piston 33 is located outside the first housing 31 and the other end side thereof is installed in the first housing 31 so as to be linearly movable. The inside of the first housing 31 is partitioned into first and second spaces 31a and 31b (see FIGS. 3A and 3B) by the other end side of the first piston 33. A pair of bearings 37a and 37b are provided on the rear surface of the protective wall 10 so that the chain 35 is supported by the bearings 37a and 37b. That is, the chain 35 is supported by the bearings 37a and 37b to form a closed curve, and is connected to one end side of the first piston 33 to rotate forward and backward as the first piston 33 linearly reciprocates. More specifically, the chain 35 is connected to one end side of the piston 33 while forming a long elliptical closed curve. At this time, the chain 35 and the piston 33 are installed so that the linear movement path of the piston 33 exists on the rotation path of the chain 35. Thus, when the piston 33 linearly reciprocates, the chain 35 rotates forward and backward.

In addition, a pair of automatic doors 21a and 21b are connected to the chain 35, respectively, where one of the automatic doors 21a and the other automatic door 21b is connected to the chain 35 Q1 and Q2. The point symmetry is achieved based on the central portion of the imaginary line L connecting the paired bearings 37a and 37b. That is, one automatic door 21a and the other automatic door 21b are connected to upper and lower portions of the chain 35 with respect to the center of the chain 35 to form point symmetry. Therefore, when the chain 35 rotates forward and backward, they move away from each other and slide toward each other.

The power generating unit 40 is installed outside the protective wall 10. The power generator 40 has a compressor 41 for generating pneumatic pressure for linearly reciprocating the first piston 33 and first and second solenoid valves 43a and 43b.

The compressor 41 communicates with the first and second spaces 31a and 31b of the first housing 31 partitioned by the first piston 33, respectively, to supply air pressure into the first housing 31. In addition, the first solenoid valve 43a is installed in a flow path between the compressor 41 and the first housing 31, and the air pressure is controlled by the control unit 50 (see FIGS. 3A and 3B) in the first housing. It selectively supplies to the 1st and 2nd spaces 31a and 31b of (31). As a result, the first piston 33 rotates the chain 35 forward and backward while linearly reciprocating. That is, when the pneumatic pressure is supplied to the first space 31a, the chain 35 rotates in the clockwise direction so that the paired automatic doors 21a and 21b are close to each other, and the pneumatic pressure is supplied to the second space 31b. When the chain 35 rotates counterclockwise, the pair of automatic doors 21a and 21b are far from each other.

On one side and the other side of the protective wall 10, the first and second sensors 51 and 53 which detect the arrival of the electric vehicle 100 and the opening and closing of the door 101 of the electric vehicle 100 and transmit them to the control unit 50. ) Is installed. The controller 50 receives the signals transmitted from the first and second sensors 51 and 53 and controls the first solenoid valve 43a as appropriate.

In addition, support rails 61 and 63 are supported on the protective wall 10 and the automatic door 20, respectively, and the supporting rails 65 supporting the bottom of the automatic door 20 are provided below the protective wall 10. Is installed. The support rails 61 and 63 and the support rails 65 help the automatic door 20 to slide smoothly.

The operation of the automatic door according to the present embodiment configured as described above will be described with reference to FIGS. 3A and 3B. 3a and 3b is a view showing the operation of the automatic door installed in the protective wall according to an embodiment of the present invention.

As shown in FIG. 3A, it is assumed that the automatic doors 21a and 21b protrude to the outside of the protective wall 10 so that the gap between the adjacent protective walls 10 is closed. In this state, when the arrival signal of the electric vehicle 100 and the signal that the door of the electric vehicle 100 has been opened are transmitted to the control unit 50 through the first and second sensors 51 and 53, the control unit 50 generates the first signal. The solenoid valve 43a is controlled so that the pneumatic pressure generated by the compressor 41 is supplied to the first space 31a of the first housing 31. Then, as the first piston 33 moves to the left, the chain 35 is rotated clockwise, thereby bringing the paired automatic doors 21a and 21b closer together. Then, as shown in FIG. 3B, since the automatic doors 21a and 21b are positioned inside the protective wall 10, the gap between the adjacent protective walls 10 is opened.

Thereafter, when the door 101 of the electric vehicle 100 is closed and the electric vehicle 100 starts, the first and second sensors 51 and 53 transmit this state to the controller 50. Then, the controller 50 controls the first solenoid valve 43a such that the pneumatic pressure of the compressor 41 is supplied to the second space 31b of the first housing 31. Then, since the first piston 33 is moved to the right side, the chain 35 rotates counterclockwise, whereby the paired automatic doors 21a and 21b are separated from each other, as shown in FIG. 3A. The gap between the adjacent protective walls 10 is closed.

Next, with reference to Figure 4 will be described a scaffolding portion that compensates for the gap between the platform and the electric vehicle. Figure 4 is an exploded perspective view of the scaffolding portion according to an embodiment of the present invention.

As shown, a case 60 having a lower case 60a and an upper cover 60b and having an open front surface is provided. The case 60 is installed in the boarding point 200 between the protective walls 10 adjacent to each other so that the front surface thereof faces the track side. Inside the case 60, a plurality of magnetic rails 61 having a rectangular pillar shape are installed toward the front and rear sides of the case 60, and insertion paths 61a are provided on both sides of the case rail 61. Is formed. In addition, insertion rails 63a and 63b are disposed on both inner side surfaces of the case 60 so as to face each other.

The footrest 70 is slidably inserted and supported by the jail 61 and the insertion rails 63a and 63b. In detail, depressions 71 recessed inwardly are formed on both side surfaces of the scaffold 70, and rollers 73 are installed in the depressions 71. Thus, when both side end sides of the footrest 71 are inserted into the insertion rails 63a and 63b, the roller 73 contacts the insertion rails 63a and 63b. In addition, the bottom surface of the footrest 70 is provided with a male-shaped male rail 75, and the insertion protrusions 75a opposed to each other are formed inside both sides of the male rail 75. As shown in FIG. The insertion protrusion 75a is inserted into the insertion path 61a of the jail 61. That is, both side surfaces of the scaffold 70 and the male rail 75 are inserted into and supported by the insertion rails 63a and 63b and the jail rail 61 installed in the case 60, and thus the scaffold 70 is supported by the case ( 60) is slidably installed. Therefore, the footrest 70 compensates for the gap between the electric vehicle 100 and the boarding point 200 while entering and leaving the case 60.

Inside the case 60, a second driving unit 80 having a second housing 81 and a second piston 83 to linearly reciprocate the footrest 70 is installed. The second housing 81 is installed inside the case 60 to form a predetermined closed space. One end side of the second piston 83 is located outside the second housing 81 and coupled to the engaging piece 77 provided on the bottom surface of the scaffold 70. The other end side of the second piston 83 is installed in the second housing 81 so as to be linearly movable, and the first and second spaces 81a and 81b (see FIG. 5) are formed inside the second housing 81. ). Therefore, when the second piston 83 linearly reciprocates, the footrest 70 compensates the gap between the electric vehicle 10 and the landing 200 while moving in and out of the case 60.

The compressor 41 of the power generating unit 40 described above communicates with the first and second spaces 81a and 81b of the second housing 81 respectively partitioned by the second piston 83. A channel for selectively supplying the pneumatic pressure to the first and second spaces 81a and 81b of the second housing 81 under the control of the controller 50 in the flow path between the compressor 41 and the second housing 83. 2 Solenoid valve 43b is installed.

The upper cover of the case 60 is provided with a pivoting cover 66 for opening and closing the front of the case 60 while the footrest 70 rotates as the case 60 enters and exits. And, the inner side of the case 60 is provided with a heating wire 68 to operate by receiving a signal from the temperature sensor 67 and the temperature sensor 67. That is, when the temperature sensed by the temperature sensor 67 is less than or equal to a predetermined temperature, the heating wire 68 generates heat to prevent freezing of components and the footrest 70, which are embedded in the case 60.

In addition, the support 69 is provided on the other inner side of the case 60. The support 69 is in contact with the bottom surface and the upper cover 60b of the lower case 60a, respectively, to prevent the case 60 from being deformed by the load applied from the upper side of the case 60. In addition, a foot passage 70 through which the support base 69 passes is formed in the footrest 70 to prevent the linear motion of the footrest 70 from being disturbed by the support base 69.

The operation of the scaffold according to the present embodiment will be described with reference to FIG. 5. 5 is a view showing an operating state of the scaffold according to an embodiment of the present invention.

As shown, it is assumed that the gap between the protective wall 10 is closed by the automatic door 20, and the state in which the footrest 70 is located inside the case 60 is an initial state. In this state, when the arrival signal of the electric vehicle 100 and the signal that the door of the electric vehicle 100 is opened are transmitted to the control unit 50 through the first and second sensors 51 and 53, the control unit 50 generates a first signal. 2 solenoid valve 43b is controlled so that the pneumatic pressure generated by the compressor 41 is supplied to the first space 81a of the second housing 81. Then, the second piston 83 is moved to the front, thereby filling the gap between the electric vehicle 100 and the landing 200 as the footrest 70 protrudes out of the case 60.

Thereafter, when the door of the electric vehicle 100 is closed and the electric vehicle 100 starts, the first and second sensors 51 and 53 transmit this state to the control unit 50. Then, the controller 50 controls the second solenoid valve 43b such that the pneumatic pressure of the compressor 41 is supplied to the second space 81b of the second housing 81. As a result, the second piston 83 moves backward, thereby inserting the scaffold 70 into the case 60.

6A and 6B are diagrams illustrating an operating state of a safety device according to an embodiment of the present invention.

In FIG. 6A, the gap between the adjacent guard walls 10 is closed by the automatic door 20 installed in the guard wall 10, and the footrest 70 is positioned inside the case 60. In this state, when the door 101 of the electric vehicle 100 is opened, as shown in FIG. 6B, the gap between the adjacent protective walls 10 is opened by the automatic door 20, and the electric vehicle 100 and the platform The gap between the 200 is compensated by the footrest 70 protruding from the case 60.

As described above, in the safety device of the platform for an electric vehicle according to the present invention, the gap between the adjacent protective walls is opened only when the electric vehicle arrives at the platform and the door of the electric vehicle is opened. Therefore, there is no risk of passengers falling from the platform to the track, so that safety accidents can be prevented.

In addition, since the gap between the electric vehicle and the platform is compensated by the scaffold, there is no fear that the passengers' feet fall into the gap between the electric vehicle and the platform. Therefore, safety accidents are further prevented.

In the above, the present invention has been described in accordance with one embodiment of the present invention, but those skilled in the art to which the present invention pertains have been changed and modified without departing from the spirit of the present invention. Of course.
