Description

Technical Field

[0001] This utility model relates to the field of railway EMU sleeper berths, specifically a railway EMU sleeper berth. Background Technology

[0002] As an important facility for long-distance passenger transport, the core requirements for sleeper berths on high-speed trains are comfort, safety, space utilization, and privacy protection.

[0003] Traditional sleeper berths may rely solely on a single pull rope for restraint or simple buckles for fixation. Vibrations and bumps during train operation can easily cause the sleeper berth to loosen or unlock unexpectedly, leading to uncontrolled overturning and posing a safety hazard. Utility Model Content

[0004] The present invention aims to provide a sleeper berth for railway EMU trains to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sleeper berth for a railway EMU includes a sleeper frame and a mounting bracket. The sleeper frame holds a sleeper mattress. The sleeper frame is detachably connected to a support, and the support is rotatably connected to a connector. The mounting bracket is rotatably connected to a gas spring, and the connector is rotatably connected to the telescopic end of the gas spring. The sleeper frame is detachably connected to a first mounting plate and a second mounting plate. The first mounting plate is connected to four corner locks, and the four corner locks are connected to connecting plates. The connecting plates are rotatably connected to pull ropes. The first and second mounting plates are each connected to a locking device, which includes a fixing pin. The second mounting plate is slidably connected to a sliding rod, and the pull rope is connected to the sliding rod. The fixing pin is connected to the sliding rod. The sleeper frame is connected to a sleeve, and the fixing pin is slidably connected to the sleeve. The mounting bracket has a fixing hole, and the fixing pin cooperates with the fixing hole. The connection method between the locking device and the first mounting plate is the same as the connection method between the locking device and the second mounting plate.

[0007] Preferably, the second mounting plate is detachably connected to a fixed seat, and the slide rod is fitted with a telescopic spring. The two ends of the telescopic spring are respectively connected to the fixed seat and the fixed pin. The connection method between the fixed seat, the telescopic spring and the first mounting plate is the same as the connection method between the fixed seat, the telescopic spring and the second mounting plate.

[0008] Preferably, mounting plate one and mounting plate two are respectively connected to positioning plates, and the two positioning plates are connected to a protective sleeve, through which the pull rope passes.

[0009] Preferably, the sleeper frame is connected to a button, the mounting bracket is connected to a telescopic support pin, and the telescopic support pin is electrically connected to the button.

[0010] Preferably, the sleeping mat has a double-layer structure, with the upper layer being silicone material and the lower layer being polyurethane high-resilience foam material, and the silicone material and polyurethane high-resilience foam material are integrally formed by sewing.

[0011] Preferably, the sleeper frame is detachably connected to railings.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0013] (1) This solution incorporates a four-corner lock, connecting plate, pull rope, and locking device. The four-corner lock, via the connecting plate, drives the pull rope to control the extension and retraction of the fixing pin. The fixing pin is inserted into the fixing hole of the mounting bracket to achieve the main limit. After the fixing pin is inserted into the fixing hole of the mounting bracket, a mechanical hard connection is formed, which can withstand the gravity after the berth is flipped and the vibration load during train operation. Compared with the traditional pull rope that only relies on friction for limit, the mechanical hard connection has stronger fatigue resistance and is not easy to loosen after long-term use, ensuring that the berth remains stable throughout the entire operation. It effectively maintains the berth's locked state, significantly reducing the risk of accidental unlocking and improving safety. At the same time, the four-corner lock requires a special key to drive, preventing accidental retraction of the fixing pin due to passenger misoperation. This is especially suitable for travel scenarios with children, reducing the safety risks caused by human operation from the source. By setting up a gas spring, the gas spring extension end drives the berth frame to flip within the range of 0° to 70°. The compressed gas inside the gas spring provides reverse thrust, allowing a single person to easily complete the flipping or lowering action, which is especially convenient for female passengers or the elderly. Furthermore, the damping characteristics of the gas spring can control the flipping speed, avoiding the impact or noise caused by uneven force during traditional manual flipping, thus improving the smoothness of operation.

[0014] (2) By setting a telescopic spring, when the pull rope breaks, the spring force can still maintain the fixed pin part inserted into the fixed hole, forming an emergency limit, and preventing the berth from accidentally flipping over due to complete loss of fixation.

[0015] (3) By setting up a protective sleeve, the wear caused by friction between the pull rope and the frame can be reduced. The positioning plate ensures the stability of the pull rope transmission path and avoids the extension and retraction of the fixing pin due to the pull rope offset and jamming, thus improving the reliability of operation.

[0016] (4) By setting the button and telescopic support pin, after flipping into place, press the button and the support pin will pop out to further limit the berth. Even if the main limit pin fails due to the pull rope breaking or other reasons, the support pin can still provide load-bearing force through physical contact to prevent the berth from suddenly flipping over, thus achieving "dual protection of main and auxiliary limit".

[0017] (5) By setting up silicone material and polyurethane high-resilience foam material, the upper silicone material is soft and conforms to the curve of the human body, and the lower polyurethane high-resilience foam material provides support. It is formed in one piece by sewing process, which can effectively disperse the pressure of lying down and reduce the pressure on the protruding parts of the bones. The comfort is greatly improved compared with traditional palm grass mats or single sponge mats, and it is especially suitable for passengers who sit for a long time.

[0018] (6) By setting up railings, it is possible to prevent passengers from falling accidentally while sleeping or when the train is shaking, which is especially suitable for the safety protection of passengers in the upper berth. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0026] like Figure 1-5The sleeper berth shown includes a sleeper frame 5 and a mounting bracket 1. A sleeper pad 8 is placed on top of the sleeper frame 5. The sleeper frame 5 is a flip-up structure with a flip angle of 70 degrees. Supports 3 are detachably connected to both ends of the sleeper frame 5. Connecting parts 15 are rotatably connected to both ends of the support 3. The mounting bracket 1 has two sets. Gas springs 2 are rotatably connected to the two sets of mounting brackets 1. The two connecting parts 15 are rotatably connected to the corresponding telescopic ends of the gas springs 2. The extension and retraction of the gas springs 2 drives the sleeper frame 5 to swing up and down, thereby adjusting the sleeper angle. The bottom ends of the sleeper frame 5 are detachably connected to mounting plates 11 and 19, respectively, by bolts. Mounting plate 11 is connected to a four-corner lock 12, which requires a special key to operate. The four-corner lock 12 is connected to a connecting plate 13, and pull ropes 17 are rotatably connected to both ends of the connecting plate 13. Mounting plates 11 and 19 are respectively connected to locking devices, which include a fixing pin 22. Mounting plate 19 is slidably connected to a slide rod 16, and the corresponding pull ropes 17 are connected to the slide rod 16. The fixing pin 22 is connected to the slide rod 16. The sleeper frame 5 is connected to a sleeve 24, and the fixing pin 22 is slidably connected to the sleeve 24. The mounting bracket 1 has a fixing hole 23, and the fixing pin 22 cooperates with the fixing hole 23. The connection method between the locking device and mounting plate 11 is the same as the connection method between the locking device and mounting plate 19. When the pull rope 17 is pulled, the slide bar 16 slides against the spring force, causing the fixing pin 22 to be pulled out of the fixing hole 23 and the locking is released; after the pull rope 17 is released, the spring returns to its original position and pushes the fixing pin 22 into the fixing hole 23 to achieve automatic locking.

[0027] like Figure 2 , 5 As shown, mounting plate 19 is detachably connected to a fixed base 20. A telescopic spring 21 is sleeved on the slide rod 16. The two ends of the telescopic spring 21 are connected to the fixed base 20 and the fixing pin 22, respectively. The connection method between the fixed base 20, the telescopic spring 21 and mounting plate 11 is the same as the connection method between the fixed base 20, the telescopic spring 21 and mounting plate 19. Mounting plates 11 and 19 are respectively connected to positioning plates 18. The two positioning plates 18 are connected to a protective sleeve 14. The pull rope 17 passes through the protective sleeve 14 to prevent the pull rope 17 from wearing or shaking.

[0028] like Figure 1 As shown, a button 4 is connected to the bottom of the sleeper frame 5, and telescopic support pins 6 are connected to the inner walls of the two mounting brackets 1 respectively. The telescopic support pins 6 are electrically connected to the button 4, and can extend out of the mounting bracket 1 when extended. When the button 4 is pressed, the telescopic support pins 6 extend and extend out of the mounting bracket 1 to further fix the position of the sleeper frame 5. The sleeper mat 8 adopts a double-layer structure, with the upper layer being silicone material 10 and the lower layer being polyurethane high-resilience foam material 9. The silicone material 10 and polyurethane high-resilience foam material 9 are integrally formed by sewing. The sleeper frame 5 is detachably connected to a railing 7.

[0029] The specific implementation process is as follows:

[0030] In use, gently lift one end of the berth. The compressed gas inside the gas spring 2 generates a reverse thrust, counteracting the weight of the berth. This allows the flipping process to be completed with minimal effort. Once flipped into position, the gas spring 2 has a damping or hydraulic locking structure. After adjusting to the target angle, the gas spring 2 automatically maintains its current extension / retraction state, providing initial support and preventing the berth frame 5 from sliding due to gravity. Then, the four-corner lock 12 is activated by a special key. The four-corner lock 12 rotates the connecting plate 13. After releasing the pull rope 17, the spring returns to its original position, pushing the fixing pin 22 into the fixing hole 23 for automatic locking. Finally, pressing button 4 energizes and extends the telescopic support pin 6, further limiting the berth's position.

[0031] When unlocking is required, the four-corner lock 12 is driven by a special key, causing the pull ropes 17 at both ends to be pulled synchronously. The pull ropes 17 pass through the protective sleeve 14, causing the slide rods 16 on the mounting plate 11 and mounting plate 2 to slide. When the slide rods 16 slide, they compress the telescopic springs 21 sleeved on them, and at the same time, they cause the fixing pins 22 to be pulled out of the fixing holes 23 of the mounting bracket 1, releasing the mechanical lock between the sleeper frame 5 and the mounting bracket 1.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
