Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and specifically to a flipping structure for a sleeper berth in a rail vehicle. Background Technology

[0002] Rail vehicles are transportation vehicles that must run along tracks. They are characterized by self-guiding, low running resistance, and the ability to operate in formation. Rail vehicles used for long-distance passenger transport usually have sleeper berths in some carriages to meet the needs of different groups of people.

[0003] Traditional fixed sleeper cars have four to six sleeper beds in a compartment, arranged in pairs facing each other with an aisle in the middle. This limits the vertical space available to passengers, especially when the sleeper berths are empty. Therefore, in the course of development, sleeper flip-over structures have emerged to reduce space occupancy.

[0004] However, in actual use, the sleeper berth flipping structure requires a connecting structure to connect the partition in the carriage with the sleeper berth. However, the connecting structure will occupy some space, which will reduce the aisle distance between two opposite berths in a carriage compartment. This will cause inconvenience to people's movement and affect the riding experience of passengers. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a berth flipping structure for rail vehicles, which reduces the space occupation caused by adding a berth flipping structure while maintaining the original aisle length, and improves the riding experience of passengers.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a tilting structure for a sleeper berth in a rail vehicle, including a car compartment, with limit grooves on both sides of the car compartment and limit steel plates fixedly connected in the limit grooves. Connecting plates are fixedly connected to the limit steel plates by bolts. Support frames are fixedly connected to both sides of one end of the connecting plate. Limit grooves are opened on opposite sides of the two support frames, and sliders are slidably connected in the limit grooves. Rotating plates are rotatably connected to opposite sides of the two sliders via rotating shafts. The upper end of the rotating plates is fixed... A mattress is connected to the rotating plate. A handle is fixedly connected to the end of the rotating plate away from the mattress. A guardrail is fixedly connected to the upper part of the rotating plate away from the limiting steel plate. Magnetic strips are evenly fixedly connected within the compartment, and the magnetic strips correspond to the guardrails. A locking strip is fixedly connected to the opposite side of each of the two support frames, and the locking strip is located on the bottom side of the support frame. A connecting sleeve is fixedly connected to the opposite side of each of the two support frames. A spring pull rod is inserted into each connecting sleeve. A slot is inserted into the end of the spring pull rod, and the slot is located at the end of the slider away from the rotating shaft.

[0007] As a preferred technical solution of this utility model, the upper and lower ends of the slider are provided with first grooves, and a pulley is rotatably connected in the first groove. The pulley contacts the limiting groove to reduce the friction of the slider movement.

[0008] As a preferred technical solution of this utility model, a sliding rod is inserted into the slider, and a spring is sleeved on the side of the sliding rod away from the connecting plate, with one end of the spring in contact with the slider. By setting the sliding rod, the slider can move stably, and the relative stability between the slider and the rotating plate can be improved.

[0009] As a preferred technical solution of this utility model, a pad is in contact with one side of the slider, the pad is fixedly connected to the connecting plate, and the pad is fixedly connected to the slide rod. By setting the pad, the collision and wear between the slider and the support frame can be reduced when the slider moves.

[0010] As a preferred technical solution of this utility model, the bottom ends of the support frame and the card strip are both fixedly connected with reinforcing ribs. The reinforcing ribs are made of stainless steel. By setting the reinforcing ribs, the stability of the support frame and the card strip can be increased.

[0011] This utility model has the following advantages: by setting six opposing limiting steel plates and support frames on both sides of the compartment, the limiting rod and slider cooperate with the adjustable rotating plate, and the mattress and rotating plate can be rotated and stored by magnetic attraction of the limiting rails. At the same time, the support frame and the locking strip allow the rotating plate to unfold, and the connecting sleeve and spring pull rod near the compartment limit the slider, thereby allowing the mattress to unfold and provide service. Moreover, the slider can move within the limiting groove, which can reduce the space occupation problem caused by adding a berth flipping structure while maintaining the original aisle length.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The diagram illustrates a tilting structure for a sleeper berth in a rail vehicle, comprising a car compartment 1. Limiting grooves are formed on both sides of the car compartment 1, and limiting steel plates 2 are fixedly connected within these grooves. The limiting steel plates 2 are limited by the car compartment 1, improving stability when connecting berths. Connecting plates 3 are bolted to the limiting steel plates 2. Support frames 4 are fixedly connected to both sides of one end of the connecting plate 3. Limiting grooves 5 are formed on opposite sides of the two support frames 4, providing movement for sliders 6 and facilitating the limiting of sliders 6. The sliding distance is such that a slider 6 is slidably connected within the limiting groove 5. Each of the two sliders 6 has a rotating plate 8 rotatably connected to its opposite side via a rotating shaft 7. A mattress 9 is fixedly connected to the upper end of the rotating plate 8. A handle 19 is fixedly connected to the end of the rotating plate 8 away from the mattress 9. In manual rotation, one hand pushes the rotating plate 8 away from the connecting plate 3, and the other hand pulls the handle 19, causing the rotating plate 8 to rotate. The guardrail 10 is close to the limiting steel plate 2. The upper end of the rotating plate 8 away from the limiting steel plate 2 is fixedly connected to the guardrail 10 (the guardrail 10 can...). The protective railing 10 with a telescopic structure is replaced to further reduce the space occupied by the rotating plate 8 and mattress 9 after rotation and storage (the distance between the two connecting sleeves 12 can be adjusted accordingly). Magnetic strips 20 are evenly fixedly connected inside the compartment 1. When the slider 6 is located at the connecting sleeve 12 on the side away from the connecting plate 3, the end of the spring rod 13 is inserted into the slot 14, so that the protective railing 10 is perpendicular to the limiting steel plate 2. When the slider 6 is close to the connecting sleeve 12 on the side of the connecting plate 3, it forms a connection with the slot 14. When the mattress 9 is unfolded, the magnetic strip 20 corresponds to the guardrail 10. Each of the two support frames 4 has a fixed strip 11 on its opposite side, and the strip 11 is located on the bottom side of the support frame 4. Each of the two support frames 4 has a fixed connecting sleeve 12 on its opposite side, and each connecting sleeve 12 has a spring pull rod 13 inserted into it. The spring pull rod 13 can be manually pulled so that the end of the spring pull rod 13 is no longer inserted into any slot 14. The end of the spring pull rod 13 is inserted into a slot 14, and the slot 14 is located at the end of the slider 6 away from the pivot 7.

[0018] The slider 6 has a first groove at both the upper and lower ends. A pulley 15 is rotatably connected in the first groove. The pulley 15 contacts the limiting groove 5. By setting the pulley 15, the friction between the slider 6 and the limiting groove 5 can be reduced, which facilitates the movement of the slider 6.

[0019] The slider 6 is fitted with a slide rod 17. A spring is sleeved on the side of the slide rod 17 away from the connecting plate 3, and one end of the spring contacts the slider 6. By setting the spring, stress can be provided, which makes it easier for the rotating plate 8 and the mattress 9 to unfold, and makes the mattress 9 more stable when providing support.

[0020] Among them, the slider 6 has a pad 18 in contact with one side. Figure 2 A shim 18 is also provided near the spring side. The shim 18 is fixedly connected to the connecting plate 3 and the slide rod 17. By providing the shim 18, the movement of the slider 6 can be buffered.

[0021] The bottom ends of the support frame 4 and the clip 11 are both fixedly connected to the reinforcing ribs 16, which are made of stainless steel. The reinforcing ribs 16 further increase the stability of the mattress 9 when it is unfolded, which is the bottom side of the support frame 4 and the clip 11.

[0022] Working principle: When the mattress 9 is unfolded, the slider 6 approaches the connecting plate 3 and corresponds to the connecting sleeve 12 on the side close to the connecting plate 3. At this time, the spring pull rod 13 on the side close to the connecting plate 3 inserts into the slot 14. Then, the bottom side of the rotating plate 8 contacts the upper end of the locking strip 11, and the mattress 9 unfolds. When the mattress 9 rotates until the guardrail 10 contacts the magnetic strip 20, the spring pull rod 13 in the connecting sleeve 12 on the side away from the connecting plate 3 inserts into the slot 14 of the slider 6. At this time, the rotating plate 8 and the limiting steel plate 2 are parallel, thus providing rotation storage. Unlike the existing rotatable bunk flipping structure, the slider 6 can move within the limiting slide groove 5, thereby saving the space occupied by the flipping structure and solving the problem of reduced aisle distance between two opposite beds in a compartment 1. It also solves the problem of inconvenient movement for passengers and improves the riding experience.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
