[0034] The technical solutions of the present application will be described below in combination with Figures 1-4 The structure of the novel large-opening platform door of the present application is described.

[0035] As Figure 1As shown, the novel super-large opening platform door provided by the embodiment of the present application comprises a fixed door, a sliding door, a transmission mechanism and a detection assembly. The fixed door is internally provided with a support beam 12, and the support beam 12 is internally embedded with a plurality of rollers 13 which are used to jointly support and guide the sliding door to slide relative to the fixed door. The transmission mechanism is installed at the middle part of the sliding door in the height direction and is used to drive the sliding door to slide relative to the fixed door, thereby realizing the opening and closing of the sliding door. The detection assembly is used to detect whether there is any residual object between the platform door and the train body.

[0036] The novel super-large opening platform door provided by the embodiment of the present application jointly supports and guides the sliding door to horizontally and telescopically slide relative to the fixed door by means of the support beam 12 and the plurality of rollers 13 which are embedded in the support beam 12, thereby solving the problem of poor structural strength of the platform door when the opening degree of the platform door is increased. The opening degree of the platform door can be greater than 7m.

[0037] As shown in the drawings, Figure 1 and Figure 2 As shown, the fixed door comprises a door frame column 1, a bottom plate 2, a top plate 3, a side plate 4, a vertical plate 5 and a door plate 6. A plurality of door frame columns 1 are sequentially arranged along the length direction of the bottom plate 2, and the plurality of door frame columns 1 are arranged at intervals. The two end portions of each bottom plate 2 are fixed to the bottom fixing seat of the door frame column 1 by means of bolts, and the plurality of bottom plates 2 are sequentially connected to form the bottom surface of the fixed door. The two end portions of each top plate 3 are fixed to the top fixing seat of the door frame column 1 by means of bolts, and the plurality of top plates 3 are sequentially arranged to form the top surface of the fixed door. The vertical plate 5 is installed on the opposite sides of the door frame column 1. The top portion of each door plate 6 abuts against the corresponding top plate 3, the bottom portion abuts against the corresponding bottom plate 2, and the side edge abuts against the vertical plate 5 or the side plate 4. The staggered arrangement of the door plate 6 and the vertical plate 5 forms the front surface and the back surface of the fixed door. The two side plates 4 are fixed to the two door frame columns 1 at the most edge in the length direction by means of bolts. The bottom plate 2 and the top plate 3 are provided with grooves corresponding to the two sides in the length direction of the fixed door, and the side plate 4 is fixed through the grooves. One of the side plates 4 is provided with a through hole for the sliding door to slide. It should be noted that the length direction refers to the length direction of the fixed door, i.e. the sliding direction of the sliding door, the front surface refers to the side of the door body facing the passengers, and the back surface refers to the side of the door body facing away from the passengers.

[0038] Therefore, the fixed door provided by the embodiment of the present application forms a closed cavity by the mutually connected bottom plate 2, top plate 3, side plate 4, vertical plate 5 and door plate 6. The sliding door slides in the fixed door, and the use life of the transmission mechanism can be reduced by shielding the top plate 3 to reduce the rain, snow and dust from entering the fixed door. In addition, the fixed door has a simple structure, a large space for accommodating the sliding door and the transmission mechanism inside, which saves materials and meets the space requirement.

[0039] As shown in the drawings, Figure 3As shown, the sliding door includes a sliding door frame rod 7, a glass pressure plate 10, and tempered glass 11. The sliding door frame rod 7 includes an upper sliding door frame rod and a lower sliding door frame rod, each of which is provided with a fixed connecting piece 8 and a tempered glass hole 9. Each fixed connecting piece 8 is connected to two glass pressure plates 10 by a fastening bolt. The tempered glass 11 is fixed by the interlayer of the double-layer glass pressure plate 10 and the tempered glass hole 9, thereby forming a door leaf that can slide horizontally within the fixed door.

[0040] The support beam 12 includes an upper support beam and a lower support beam. Each door frame column 1 is provided with a through hole corresponding to the upper support beam and the lower support beam. The upper support beam and the lower support beam respectively pass through the upper and lower parts of each door frame column 1 and are fixed together by fastening bolts. A plurality of rollers 13 are installed along the length direction at the bottom of the upper support beam and the top of the lower support beam.

[0041] Rollers 13 are mounted on support beams 12 via rolling bearings to increase the sliding door's support points and prevent deformation during long-term use. Preferably, rollers 13 are nylon rollers. The sliding door frame rod 7 is a round rod that aligns with the concave surface of roller 13, providing support and guidance for the horizontal telescopic movement of the sliding door leaf. This ensures stable horizontal sliding of the sliding door and prevents lateral tipping during sliding.

[0042] The transmission mechanism includes a reduction motor 14, a driving sprocket 15, a driven sprocket, and a transmission chain 17. The reduction motor 14 is fixed to the doorframe column 1 on the side of the fixed door. The driving sprocket 15 is keyed to the power output shaft of the reduction motor 14. The driven sprocket is fixed to the doorframe column 1 on the side where the sliding door slides out from the fixed door. The driving sprocket 15 and the driven sprocket are connected by the transmission chain 17. The transmission chain 17 includes multiple chain connecting pieces in a "F" shape, with through holes at each end for securing the glass pressure plate 10 and a through hole in the middle for connecting to the chain. When the reduction motor 14 drives the transmission chain 17 to roll, the sliding door expands and contracts horizontally along with the chain connecting pieces.

[0043] The transmission mechanism provided in the embodiment of the present invention adopts sprocket transmission, which has high precision and does not require a tensioning pulley, and has a long service life compared to belt transmission.

[0044] The main driving sprocket 15 and the driven sprocket are located at the middle position of the fixed door in the height direction, and the chain connecting piece is fixedly connected with the sliding door. When the transmission chain 17 is conveyed forward, the sliding door moves and is outputted to the outside of the fixed door. The sliding door has two states of opening and closing. When the sliding door slides out of the fixed door, i.e. the sliding door is in the closed state, the chain connecting piece connected with the sliding door is in the first position. When the sliding door is in the open state, the chain connecting piece connected with the sliding door is in the second position. The first position and the second position are both located on the chain on the same side of the main driving sprocket 15 and the driven sprocket. The horizontal movement of the sliding door in the fixed door is realized by the transmission chain 17.

[0045] As shown in Figure 4 , the detection assembly includes a force receiving member 19, a universal force sensor 20 and a sensor bracket 21. The force receiving member 19 is in the shape of a flat key, which can wrap the one end of the horizontal telescopic sliding of the sliding door frame rod 7. The sensor bracket 21 is provided with two groups, which are respectively embedded in the one end of the horizontal telescopic sliding of the upper sliding door frame rod and the one end of the horizontal telescopic sliding of the lower sliding door frame rod. The universal force sensor 20 is fixed on the sensor bracket 21. The spring on the universal force sensor 20 is connected with the force receiving member 19. When the platform door is opened or closed, in order to prevent the passenger from staying between the platform door and the train body due to reasons, causing a safety accident, if the force receiving member 19 is touched, the sliding door will stop moving, and after the touch disappears, the sliding door will continue to slide. When the number of touches in a single switch reaches the preset upper limit, the corresponding alarm will be triggered, so as to avoid the occurrence of safety accidents.

[0046] In addition, an anti-interference optical detection element can also be used to detect whether there is a remaining object between the platform door and the train body.

[0047] When the sliding door is opened, the sliding direction of the sliding door is as shown by the arrow in Figure 3 . The reduction motor 14 drives the main driving sprocket 15, and then drives the transmission chain 17 to rotate, drags the sliding door by the chain connecting piece, and drives the sliding door to slide into the fixed door, so as to leave the boarding and alighting passage of the train and the platform, i.e. the opening of the platform door.

[0048] When the sliding door is closed, the sliding direction of the sliding door is opposite to the direction shown by the arrow in Figure 3 . The reduction motor 14 drives the transmission chain 17 to rotate, drags the sliding door by the chain connecting piece, and drives the sliding door to slide horizontally from the open position to the outside of the fixed door, so as to close the boarding and alighting passage of the train and the platform, and realize the closing of the platform door.

[0049] In summary, the large opening degree platform door provided by the application comprises a fixed door assembly, a sliding door assembly and a sensing detection assembly, the fixed door assembly is internally provided with a space allowing the sliding door assembly to horizontally and telescopically slide, and the sliding door assembly is connected with the fixed door assembly through the sliding door frame support beam 12. The structure uses the sliding door frame support beam 12 and the plurality of nylon rollers 13 embedded in the sliding door frame support beam 12 to jointly support and guide the horizontal and telescopic sliding of the sliding door assembly, thereby being able to solve the problem of poor structural strength when the opening degree of the platform door is increased, and make the platform door effectively solve the problem that the train door and the platform door cannot be centered due to the large variety of train types stopped at the platform, and avoid the safety problem of affecting normal operation caused by the failure to center.

[0050] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the application, and not to limit them; although the application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the application.
