Description

Technical Field

[0001] The present invention relates to the field of rail transit, and in particular to a rail transit riding facility. Background Art

[0002] Rail transit refers to a type of transportation tool or transportation system in which operating vehicles need to travel on specific tracks. Common rail transit includes traditional railways (ordinary railways, intercity railways and urban railways), subways, light rails and trams. Among them, on urban subways, the space is small and there are many people, and the seats in the car are not conducive to resting.

[0003] However, traditional subway seats are generally set in fixed positions and cannot be moved. When the number of people is crowded or space is needed, more space cannot be provided. It is usually considered to set the seats to be foldable to save space. However, due to the large passenger flow, the seats are not easy to clean and disinfect, which causes certain troubles to passengers. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the positions of traditional rail transit seats are fixed, and it is not easy to clean and disinfect the seats when the passenger flow is large. The purpose is to provide a rail transit riding facility to solve the above problem.

[0005] The present invention is achieved through the following technical solutions: A rail transit riding facility, comprising a carriage, wherein the carriage is provided with a plurality of doors on both sides along the width thereof, seats are respectively provided on both sides of the inner wall of the carriage close to the doors, each group of the seats is located between the adjacent doors on the same side, and shields are provided at both ends of the seats along the length direction; There is a gap between adjacent seats, and the seats include a first seat plate and a second seat plate. The end of the first seat plate and the end of the second seat plate are connected by a connecting tube. A connecting shaft is arranged between two adjacent shielding plates. The first seat plate or the second seat plate rotates through the connecting shaft after being subjected to force. The first seat plate or the second seat plate is used to bear weight when it is parallel to a horizontal plane.

[0006] In the above technical solution, by adjusting the first seat board, the passenger can choose to sit on the first seat board or the second seat board. Sitting on the two seats alternately can reduce hygiene problems. At the same time, it can also effectively avoid the problem of residual heat in the seat caused by the passenger just leaving the seat.

[0007] In some optional technical solutions, a plurality of supporting mechanisms are provided on one side of the carriage close to the seat, the supporting mechanisms including a cabinet and a rotating assembly, the rotating assembly being arranged in the cabinet, the rotating assembly including a fixed block, a movable block and a return spring, the two ends of the return spring being respectively connected to the fixed block and the movable block, the fixed block being fixedly connected to the inner wall of the cabinet, and the end of the movable block away from the return spring being connected to the first seat plate.

[0008] In the above technical solution, the fixed block and the movable block are used to support the second seat plate in the limited parallel state, and at the same time, the first seat plate in the parallel state can be restored through the reset spring.

[0009] In some optional technical solutions, the first seat plate and the second seat plate are both located outside the cabinet and are used for contacting and limiting the position of the cabinet.

[0010] In the above technical solution, the second seat plate is in contact with the cabinet body and can be used to limit the rotation in a vertical state so that the first seat plate can maintain balance.

[0011] In some optional technical solutions, the movable block is rotatably connected to the cabinet via a rotating shaft, and the top surface of the movable block is connected to the bottom surface of the second seat plate.

[0012] In the above technical solution, the movable block is used to support the second seat plate to prevent the second seat plate from being unstable.

[0013] In some optional technical solutions, a slot is provided at the top of the movable block, and a plurality of locking blocks are provided at one end of the fixed block close to the first seat plate, and the locking blocks are used to engage with the slot.

[0014] In the above technical solution, the cooperation between the clamping block and the clamping slot can limit the rotation of the movable block, thereby preventing the movable block from rotating due to gravity and torque factors.

[0015] In some optional technical solutions, the block is in the shape of a quarter sphere, and the spherical surface of the block faces the second seat plate.

[0016] In some optional technical solutions, the top surface of the clamping block is connected to a limiting shaft, the fixed block is L-shaped, a damping shaft is provided at one end of the fixed block close to the clamping block, and the limiting shaft and the damping shaft are rotatably connected.

[0017] In the above technical solution, the planar end of the clamping block applies force to the planar end of the clamping slot, and the torque acts on the fixed block through the limit shaft. The position of the fixed block is fixed, so the clamping block will be restricted in the clamping slot and the movable block will stop rotating, thereby ensuring that the compressed second seat plate can maintain balance and stability.

[0018] In some optional technical solutions, a through groove is opened in the middle part of the cabinet on one side facing the seat, and push rods are slidably connected to the cabinets on the upper and lower sides of the through groove, one end of the push rods is located outside, and the other end of the push rods is located inside the cabinet, and a number of disinfection spray bottles are detachably connected to the cabinet, one end of two push rods abut against the pressing nozzles of the disinfection spray bottles, the nozzle of the disinfection spray bottle located above the connecting tube faces the first seat plate, and the nozzle of the disinfection spray bottle located below the connecting tube faces the second seat plate.

[0019] In the above technical solution, the first seat plate or the second seat plate will come into contact with the corresponding push rod, and the push rod pushes the disinfection spray bottle, and the nozzle sprays mist disinfectant toward the corresponding first seat plate or the second seat plate, effectively reducing health hazards in public places and other problems.

[0020] In some optional technical schemes, the connecting cylinder includes a first sleeve connected to the first seat plate and a second sleeve connected to the second seat plate, the first sleeve is arranged at both ends of the first seat plate, the second sleeve is arranged in the middle of the second seat plate, the first sleeve and the second sleeve are coaxially arranged, a locking portion is arranged on the connecting shaft, and a connecting straight line groove is provided on the inner circumferential wall of the first sleeve and the second sleeve, the locking portion is used for sliding connection with the straight line groove, a groove is provided at the end of the baffle away from the connecting cylinder, the end of the connecting shaft is located in the groove, the end of the connecting shaft is connected to a handle, there is a gap between the end of the connecting shaft and the bottom surface of the groove, and a valve cover is provided at the groove.

[0021] In the above technical solution, during peak hours in the morning and evening, there are many passengers taking the rail transit. The locking part can be slid into the second sleeve of the second seat plate in advance, and then the handle can be turned to independently control the second seat plate to rotate downward 90°, and the first seat plate and the second seat plate can be unfolded to 180°, providing more standing space for passengers and greatly reducing congestion.

[0022] In some optional technical solutions, arc-shaped convex strips are provided at both ends of the first seat plate and the second seat plate along the length direction of the connecting shaft.

[0023] In the above technical solution, the arc-shaped convex strips are used to protect adjacent passengers from being injured or having their belongings pinched due to the gaps in the seats.

[0024] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The first seat plate and the second seat plate in the present invention can be switched at will according to the needs of the passengers. Whenever the state switching is completed and the passengers sit down, the unused first seat plate or the second seat plate is sprayed with disinfectant spray. After the passenger leaves the seat, the next passenger can choose to sit on the disinfected seat. The interchangeability of the first seat plate and the second seat plate can greatly reduce the environmental sanitation problems in the carriage, and also reduce the workload of the staff for daily disinfection; 2. In the present invention, when the first seat plate or the second seat plate is in a parallel state for passengers to sit on, the stability of the seat can be effectively improved through the cooperation of the block or the cabinet, so as to avoid the problem of the seat being unstable when the younger passengers sit on the seat and shake; 3. When the passenger flow is large during the morning and evening peaks, the second seat plate can be rotated downward in advance through the cooperation of the connecting shaft and the locking part, so that the first seat plate and the second seat plate are in an unfolded state, effectively reducing the problem of congestion in the carriage caused by the morning peak.

[0027] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0028] Example 1 like Figures 1 to 6 As shown, this embodiment provides a rail transit riding facility, including a carriage, wherein a plurality of doors are arranged on both sides of the width of the carriage, seats are arranged on both sides of the inner wall of the carriage close to the doors, each group of seats is located between adjacent doors on the same side, and shields are arranged at both ends of the seats along the length direction; There is a gap between adjacent seats, and the seats include a first seat plate 11 and a second seat plate 12. The end of the first seat plate 11 and the end of the second seat plate 12 are connected by a connecting tube. A connecting shaft 3 is arranged between two adjacent shielding plates. The first seat plate 11 or the second seat plate 12 rotates through the connecting shaft 3 after being subjected to force. The first seat plate 11 or the second seat plate 12 is used to bear weight when it is parallel to a horizontal plane.

[0029] like Figure 3 and Figure 4 As shown, a plurality of supporting mechanisms are arranged on one side of the carriage near the seat, the supporting mechanisms include a cabinet body 4 and a rotating assembly, the rotating assembly is arranged in the cabinet body 4, the rotating assembly includes a fixed block 21, a movable block 22 and a return spring, the two ends of the return spring are respectively connected to the fixed block 21 and the movable block 22, the fixed block 21 is fixedly connected to the inner wall of the cabinet body 4, and the end of the movable block 22 away from the return spring is connected to the first seat plate 11.

[0030] like Figures 1 to 5 As shown, the first seat plate 11 and the second seat plate 12 are both located outside the cabinet body 4 and are used for contacting and limiting the cabinet body 4 .

[0031] The movable block 22 is rotatably connected in the cabinet 4 via a rotating shaft, and the top surface of the movable block 22 is connected to the bottom surface of the second seat plate 12 .

[0032] A slot is formed at the top of the movable block 22 , and a plurality of blocks 24 are provided at one end of the fixed block 21 close to the first seat plate 11 . The blocks 24 are used to be engaged with the slot.

[0033] like Figure 4 As shown, the block 24 is in a quarter spherical shape, and the spherical surface of the block 24 faces the second seat plate 12 .

[0034] like Figure 4 As shown, the top surface of the clamping block 24 is connected to the limiting shaft 23, the fixing block 21 is L-shaped, and a damping shaft is provided at one end of the fixing block 21 close to the clamping block 24, and the limiting shaft 23 is rotatably connected to the damping shaft.

[0035] Specifically, when passengers take rail transit, the initial state of the seats, that is, the normal state, is that the first seat board 11 is vertical to the ground, and the second seat board 12 is parallel to the ground. Passengers can choose any seat to sit when they need to sit. There are gaps between adjacent seats, and each seat is independent, which can effectively prevent some passengers from deliberately sitting in multiple seats or lying on the seats in an uncivilized manner.

[0036] Due to the large daily active flow of rail transit and the large number of passengers, after the passenger sitting on the second seat board 12 leaves the current seat, the next passenger who needs to sit in this seat can choose to rotate the first seat board 11 to 90°, so that the first seat board 11 is parallel to the ground and the second seat board 12 is perpendicular to the ground. The passenger can sit on the first seat board 11 to avoid sitting in the same position with the previous passenger, which can avoid the spread of microorganisms in public places with dense populations and improve the quality of public environmental hygiene.

[0037] Regarding the rotation of the seat: in the initial state, that is, when the first seat plate 11 is vertical to the ground, the movable block 22 can be used to support the second seat plate 12. When the passenger sits on the second seat plate 12, the second seat plate 12 will first be subjected to a downward force. Since the first seat plate 11 and the second seat plate 12 are connected by a connecting tube, and the connecting tube and the connecting shaft 3 are rotatably connected, the second seat plate 12 will also be subjected to a torque, and the rotation direction is downward and toward the cabinet 4. A fixed block 21 is fixedly connected in the cabinet 4. A damping shaft is provided at one end of the L-shaped fixed block 21 facing the first seat plate 11. A limiting shaft 23 is rotatably connected to the damping shaft. A clamping block 24 is provided at the bottom end of the limiting shaft 23. The clamping block 24 is in the shape of a quarter sphere. The movable block 22 extends toward the cabinet 4 at one end of the fixed block 21, and a clamping groove that is clamped with the clamping block 24 is opened on the movable block 22. The clamping block 24 and the clamping groove are adaptively connected, and the spherical surface of the clamping block 24 faces the second seat plate 12.

[0038] Therefore, when the second seat plate 12 rotates downward due to gravity, the movable block 22 rotates accordingly. However, due to the action of the clamping block 24, the planar end of the clamping block 24 applies force to the planar end of the clamping slot, and the torque acts on the fixed block 21 through the limit shaft 23. The position of the fixed block 21 is fixed. Therefore, the clamping block 24 will be restricted in the clamping slot, and the movable block 22 will also stop rotating, thereby ensuring that the compressed second seat plate 12 can be kept balanced and stable.

[0039] When the passenger changes seats, the first seat plate 11 can be pushed in the opposite direction first, that is, the first seat plate 11 is pushed toward the cabinet body 4. The first seat plate 11 contacts the limit shaft 23 of the clamping block 24, so that the limit shaft 23 rotates toward the fixed block 21, and the clamping block 24 rotates in the opposite direction. The spherical surface of the clamping block 24 will slide out smoothly along the clamping groove. At this time, the first seat plate 11 can be normally pulled down. Because the clamping block 24 leaves the clamping groove, the movable block 22 will no longer be subject to resistance and will smoothly follow the rotation of the second seat plate 12, and finally make the second seat plate 12 perpendicular to the ground and the first seat plate 11 parallel to the ground. Because the second seat plate 12 contacts the cabinet body 4, when the passenger sits on the first seat plate 11, the first seat plate 11 is restricted and will not continue to rotate downward. On the other hand, the limit shaft 23 cooperates with the damping shaft, so the limit shaft 23 recovers slowly, and will be contacted by the rotating movable block 22 on the clamping block 24, and another limit is performed, thereby ensuring the stability of the first seat plate 11.

[0040] When the passenger sitting on the second seat plate 12 leaves, the return spring between the movable block 22 and the fixed block 21 will be stretched and deformed due to the downward rotation of the movable block 22. When the pressure of the first seat plate 11 disappears, the movable block 22 is no longer affected by the torque, and the return spring is the same. Therefore, the return spring will return to its original state, driving the movable block 22 to return to a parallel state, that is, the second seat plate 12 becomes parallel.

[0041] Example 2 like Figure 7 As shown, this embodiment is basically the same as Embodiment 1, with the only difference being that a baffle is hinged inside the cabinet body 4 located at the first seat plate 11, and the hinge axis of the baffle is located at the bottom. The baffle can follow the force of the first seat plate 11 to squeeze the movable block 22 inward. Preferably, a coil spring is also provided inside the hinge axis of the baffle to achieve a reset effect.

[0042] The baffle arrangement of the present embodiment can shield the cabinet 4 when the first seat plate 11 is in a parallel state, thereby preventing the passenger's back from being located in the gap of the cabinet 4. Moreover, since the baffle is hingedly arranged and according to the working principle in Example 1, the movable block 22 is fixed at this time, even if the passenger applies force backward with his back, the baffle will not sink into more parts of the cabinet 4, thereby providing a safe riding environment for the passengers.

[0043] Example 3 like Figure 8 As shown, a through groove is opened in the middle of the side of the cabinet 4 facing the seat, and push rods are slidably connected to the cabinet 4 on the upper and lower sides of the through groove, one end of the push rod is located outside, and the other end of the push rod is located in the cabinet 4. A plurality of disinfection spray bottles are detachably connected in the cabinet 4, and one end of the two push rods abuts against the pressing nozzles of the disinfection spray bottles. The nozzle of the disinfection spray bottle located above the connecting tube faces the first seat plate 11, and the nozzle of the disinfection spray bottle located below the connecting tube faces the second seat plate 12.

[0044] Specifically, as mentioned above, rail transit is an environment with large passenger flow and dense population. During the switching process between the first seat plate 11 and the second seat plate 12 as mentioned above, the first seat plate 11 or the second seat plate 12 will come into contact with the corresponding push rod, and the push rod pushes the disinfection spray bottle, and the nozzle sprays a mist of disinfectant to the corresponding first seat plate 11 or the second seat plate 12. Preferably, the disinfectant is an easily evaporable alcohol, which can be sprayed on the other vertical first seat plate 11 or the second seat plate 12 after the passenger takes a seat at the station. Even if the passenger only takes one station, when another passenger sits on the seat sprayed with alcohol after getting off the train, the seat has been air-dried and disinfected, which can effectively reduce health risks in public places.

[0045] Preferably, Figure 8 As shown, the two disinfectant spray bottles located above and below the cabinet 4 have different specifications. The nozzle of the disinfectant spray bottle located above is linear and faces the first seat plate 11. When the first seat plate 11 is restored to a vertical state, the nozzle of the disinfectant spray bottle above is squeezed, and the nozzle sprays alcohol. When the first seat plate 11 leaves and becomes horizontal, the nozzle of the disinfectant spray bottle above rebounds and waits for the next spray of alcohol. It should be noted that when the baffle structure in Example 2 is adopted, a hole can be opened in the middle of the baffle for the nozzle of the upper disinfectant spray bottle to pass through; the disinfectant spray bottle located below is an airbag structure, and a channel is opened under the cabinet 4 for the nozzle of the disinfectant spray bottle below to pass through. When the second seat plate 12 changes from a horizontal state to a vertical state, the airbag is squeezed, and the alcohol in the airbag is sprayed upward along the nozzle onto the surface of the second seat plate 12. Preferably, the second seat plate 12 can be an inclined surface to facilitate spraying of alcohol. At the same time, the inclined seat helps passengers relax their legs when sitting.

[0046] Example 4 The connecting tube includes a first sleeve connected to the first seat plate 11 and a second sleeve connected to the second seat plate 12. The first sleeve is arranged at both ends of the first seat plate 11, and the second sleeve is arranged in the middle of the second seat plate 12. The first sleeve and the second sleeve are coaxially arranged. A locking portion 31 is arranged on the connecting shaft 3. A connecting linear groove is provided on the inner circumferential wall of the first sleeve and the second sleeve. The locking portion 31 is used for sliding connection with the linear groove. A groove is provided at one end of the baffle away from the connecting tube. The end of the connecting shaft 3 is located in the groove. A handle is connected to the end of the connecting shaft 3. There is a gap between the end of the connecting shaft 3 and the bottom surface of the groove. A valve cover is provided at the groove.

[0047] Arc-shaped convex strips are provided at both ends of the first seat plate 11 and the second seat plate 12 along the length direction of the connecting shaft 3 .

[0048] Specifically, during peak hours such as morning and evening, there are many passengers taking rail transit, but the compartment space is limited. In order to improve the utilization rate of the compartment space and reduce congestion, before the peak hours, the corresponding staff can open the valve cover of the shutter and push the inner connecting shaft 3 to the other shutter through the handle, such as Figure 4 As shown, a connected linear groove is provided on the inner circumferential wall of the first sleeve and the second sleeve. During non-peak hours, the locking portion 31 of the connecting shaft 3 is located between the first sleeve and the second sleeve, which can be used to integrate the first seat plate 11 and the second seat. During the morning and evening peak adjustments, the locking portion 31 is only slid into the second sleeve of the second seat plate 12, and then the handle is turned to independently control the second seat plate 12 to rotate downward 90°, and the first seat plate 11 and the second seat plate 12 are expanded to 180°, providing more standing space for passengers and greatly reducing congestion. After the adjustment is completed, the valve cover can be closed, and when the morning and evening peaks are over, the valve cover can be opened again to call back the connecting shaft 3. The arc-shaped convex strip is used to play a rounded transition role at the interval between adjacent seats to avoid pinching or scratching passengers.

[0049] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
