Technical Field

[0001] An embodiment of the present invention relates to an electric vehicle platform safety device having a soft blocking member for blocking multiple rows of ropes. Background Art

[0002] The electric vehicle platform safety device performs the function of preventing safety accidents by controlling the ingress and egress of passengers' electric vehicles using ropes moving in the up-down direction. In the electric vehicle platform safety device, when viewed from the front, the ropes are arranged at constant intervals in a manner of being spaced apart from each other in the up-down direction, so obstacles (obstacles) such as the passenger's body and umbrella may easily pass between the ropes, and various safety accidents caused by this may occur.

[0003] To solve this problem, Figure 1 As shown in FIG. 1 , an electric vehicle platform safety device is developed that includes a soft blocking member 5 that blocks the front area of ​​the rope 4. However, the following problems may occur: when the rope 4 contracts or expands with temperature (seasonal) changes and / or when at least one of the ropes 4 moves in the left and right directions (see FIG. 1 ), the rope 4 may be blocked. Figure 1 When the tension of the rope 4 is adjusted by adjusting the tension of the rope 4, the rope 4 and the fixed blocking member 5 are twisted in the front-to-back or left-to-right direction, whereby the tension and / or shape of the blocking member 5 may not be maintained constantly, and obstacles may not be blocked by the blocking member 5.

[0029] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0030] The structure of the electric vehicle platform safety device according to the embodiment of the present invention is shown in FIG. Figures 1 to 7 middle.

[0031] Reference Figure 2 The electric vehicle platform safety device is a rope type platform safety door (RPSD) provided on the platform 5 to ensure the safety of passengers using electric vehicles.

[0032] The electric vehicle platform safety device may be arranged at a selected position between the entrance and exit of the platform 5 based on the travel direction of the electric vehicle. The electric vehicle platform safety device may be provided individually on the platform 5 according to the length of the platform 5, or may be provided in plurality. In the latter case, the plurality of electric vehicle platform safety devices may be arranged at intervals in a manner spaced apart from each other along the length direction of the platform 5, or may be arranged continuously.

[0033] The electric vehicle platform safety device includes a main body 10. The main body 10 includes a left column 12A and a right column 12B as a plurality of columns respectively erected on the platform 5. The left column 12A and the right column 12B are arranged at intervals in a manner of being spaced apart from each other in the longitudinal direction of the platform 5. For reference, when a plurality of columns are provided on the platform 5 and are continuously arranged in the longitudinal direction of the platform 5, the electric vehicle platform safety device may also be configured to share the columns.

[0034] exist Figure 2 In the figure, reference numeral 14 is a horizontal frame connecting the upper end of the left column 12A and the upper end of the right column 12B, and the main body 10 may further include the horizontal frame 14.

[0035] Reference Figures 2 to 5The electric vehicle platform safety device includes: a left part 20A and a right part 20B, which are respectively provided on the left column 12A and the right column 12B in a manner that they can move in the up and down directions; a lifting drive unit 30, which moves the left part 20A and the right part 20B; a plurality of rows of ropes 40, which connect the left part 20A and the right part 20B in the left and right directions between the left column 12A and the right column 12B and are separated from each other in the up and down directions; a soft blocking member 50, which is provided on the plurality of rows of ropes 40 in a manner that it can move in the left and right directions along the plurality of rows of ropes 40, so as to block the front area or the rear area of ​​the plurality of rows of ropes 40; and a tension imparting unit 60, which keeps the soft blocking member 50 in a tensioned state.

[0036] In the electric vehicle platform safety device, if the left part 20A and the right part 20B are moved upward or downward by the lifting drive unit 30, the multiple rows of ropes 40 move upward or downward together with the left part 20A and the right part 20B. The multiple rows of ropes 40 can block the passage between the left part 20A and the right part 20B when moving downward, and can block the passage between the left part 20A and the right part 20B when moving upward (refer to Figure 2 ) can release the blocking between the left component 20A and the right component 20B.

[0037] The left component 20A can accurately move in the up-down direction by being guided by a left guide rail (not shown), which can be provided in the up-down direction inside or outside the left column 12A. The right component 20B can accurately move in the up-down direction by being guided by a right guide rail (not shown), which can be provided in the up-down direction inside or outside the right column 12B.

[0038] The lifting drive unit 30 may include: a rotating component 32, which is provided at the upper and lower parts of the left column 12A in a manner that can rotate around a horizontal axis; a connecting component 34, which is suspended from the rotating component 32 and connected to the upper and lower parts of the left component 20A at both ends; and a motor 36, which rotates any one of the rotating components 32. The rotating component 32 may be a sprocket or a pulley, and the connecting component 34 may be a chain or a belt. The rotational force of the motor 36 may be transmitted to any one of the rotating components 32 through a speed reducer.

[0039] The lifting drive unit 30 can move the left side component 20A in the up-down direction by the rotating component 32, the connecting component 34, and the motor 36 to move the plurality of rows of ropes 40 and the right side component 20B connected thereto in the same direction. Alternatively, the lifting drive unit 30 can move the right side component 20B in the up-down direction to move the plurality of rows of ropes 40 and the left side component 20A connected thereto in the same direction. Alternatively, Figure 2 As shown, the lifting drive unit 30 may also simultaneously move the left component 20A and the right component 20B in the up and down directions to move the multiple rows of ropes 40 together in the same direction.

[0040] The plurality of rows of the ropes 40 may be parallel to each other in a horizontal direction corresponding to the left-right direction. The ropes 40 may be provided in plural, and the left and right sides are connected to the left component 20A and the right component 20B, respectively, and provided in plural rows by being spaced apart from each other in the up-down direction. Alternatively, the ropes 40 may be provided in plural rows by being alternately connected to the left component 20A and the right component 20B at a plurality of positions spaced apart from each other in the up-down direction.

[0041] The plurality of rows of ropes 40 may be made of a hard material and covered with rubber, synthetic resin, etc. for protection and / or corrosion prevention. Alternatively, the plurality of rows of ropes 40 may be made of a soft material.

[0042] The blocking member 50 can prevent various obstacles such as the passenger's body (hands, etc.) and umbrellas from passing between the multiple rows of ropes 40 by entirely covering the front area or the rear area of ​​the multiple rows of ropes 40. The blocking member 50 is made of soft rubber, synthetic resin, etc., and can reduce the load acting on the lifting drive unit 30 by being lightweight, thereby preventing safety accidents caused by collision with passengers.

[0043] Reference Figure 5 as well as Figure 6 The blocking member 50 has a ring component 52 at the upper and lower parts along the left-right direction, which provides an insertion space 54 for the uppermost side column and the lowermost side column of the multiple columns of ropes 40 to pass through respectively. Therefore, the blocking member 50 can move freely in the left-right direction along the multiple columns of ropes 40, and can prevent vertical deformation or detachment.

[0044] The insertion space 54 of the ring member 52 can allow the uppermost and lowermost rows of the ropes 40 to freely shrink or expand with temperature changes, and can allow the uppermost and lowermost rows of the ropes 40 to freely move in the left and right directions for adjusting tension, etc. In other words, the blocking member 50 can be prevented from shrinking, expanding or moving with the rope 40 (see Figure 4 To this end, the insertion space 54 may be formed to have a larger cross section than the rope 40. That is, the insertion space 54 may be formed to have a larger up-down and front-back dimension than the rope 40.

[0045] Reference Figure 3 as well as Figure 4 The blocking member 50 includes a reinforcing member 56 that connects the upper and lower ring members 52 in the up-down direction on the left and right sides, respectively. Although not shown, the blocking member 50 may be configured to have a porous structure between the reinforcing members 56 that structurally reinforce the left and right sides. That is, the porous structure may be provided as a structure that allows wind to pass but obstructions are difficult to pass.

[0046] The tension applying unit 60 is configured to apply tension to the left and right sides of the soft stopper 50, thereby preventing the stopper 50 from being deformed. Figure 3 as well as Figure 4 The tension imparting unit 60 includes: at least one left tensioner 60A, connecting the left side portion of the blocking member 50 (i.e., the left side reinforcing component 56 that structurally reinforces the left side of the blocking member 50) to the left side component 20A; and at least one right tensioner 60B, connecting the right side portion of the blocking member 50 (i.e., the right side reinforcing component 56 that structurally reinforces the right side of the blocking member 50) to the right side component 20B.

[0047] The left tensioner 60A can be used to push the blocking member 50 to the left (refer to Figure 4 The right side tensioner 60B can apply tension to the blocking member 50 to the right side (refer to the solid arrow on the left side of the figure) to keep the blocking member 50 in a tensioned state relative to the left side component 20A. Figure 4 The stopper 50 is kept in a tensioned state relative to the right member 20B by applying tension (solid arrow on the right side of the figure). When a plurality of left tensioners 60A and right tensioners 60B are provided, they can be arranged at intervals in a manner spaced apart from each other in the vertical direction.

[0048] The left tensioner 60A may include: two connecting parts 62, respectively connected to the right part of the left part 20A and the reinforcing part 56 on the left side; and a tension adjustment element 64, connecting the two connecting parts 62. The right tensioner 60B may also include two connecting parts 62 and a tension adjustment element 64. Obviously, the two connecting parts 62 of the right tensioner 60B are also respectively connected to the left part of the right part 20B and the reinforcing part 56 on the right side. The tension adjustment element 64 may be a spring, a turnbuckle, etc.

[0049] Figures 7 to 9 Another example of a blocking member of the electric vehicle platform safety device according to an embodiment of the present invention is shown. Figure 7 It is illustrated that the blocking member 50 may be provided in plurality for easy maintenance, arranged in the left-right direction to block the front area or the rear area of ​​the plurality of rows of ropes 40 , and connected to each other via the supporting member 70 .

[0050] When compared with the previous reference Figure 2 , Figure 3 When compared with the blocking member 50 described above, Figure 7 The plurality of blocking members 50 shown have a small left-right dimension and therefore differ only in terms of compactness, and the rest may be constructed substantially the same.

[0051] The supporting component 70 can be configured between the multiple blocking members 50 and the blocking members are set on both sides. It has insertion holes 72 for multiple rows of ropes 40 to pass through respectively and can move in the left and right directions along the multiple rows of ropes 40, and has connecting components 74 respectively connected to the blocking members 50 on both sides.

[0052] Such a support member 70 can connect the blocking members 50 on both sides to guide the integrated movement of the plurality of blocking members 50, thereby preventing the vertical intervals of the plurality of rows of ropes 40 from changing significantly, and allowing the plurality of rows of ropes 40 to freely contract or expand with temperature changes and freely move in the left-right direction for adjusting tension, etc. Fig. 9 As shown, the insertion hole 72 may be formed to have a larger cross-section than the rope 40 .

[0053] The connecting member 74 may be made of soft rubber, synthetic resin, etc. The soft connecting member 74 may ensure flexibility during the process of adjusting the tension of the plurality of stoppers 50 .

[0054] According to this variation, the left tensioner 60A can connect the blocking member 50 located at the far left to the left component 20A, and the right tensioner 60B can connect the blocking member 50 located at the far right to the right component 20B.

[0055] Although the present invention has been described above, the present invention is not limited to the disclosed embodiments and the accompanying drawings, and a person skilled in the art can make various modifications within the scope of the technical concept of the present invention.
