[0042] This application provides a concealed lower berth safety railing device to solve the problem that in related technologies, the lower berth safety protection device is directly and rigidly fixed and cannot be retracted, which leads to poor convenience when entering and exiting the lower berth and the middle section of the lower berth cannot be used for people to sit.

This achieves a retractable design and provides a stable connection between the horizontally retracted and vertically usable states, facilitating both passenger comfort and safety requirements.

[0048] In some preferred embodiments, reference Figure 10 and Figure 11 , Figure 11This is a schematic diagram showing the connection of the telescopic ends of the guardrail in a vertical state via a locking structure; the guardrail 3 is provided with an installation groove; the unlocking component 5 includes a first elastic element and a button disposed in the installation groove, and the button is connected to a first pull wire 501;

[0049] The guardrail 3 is provided with a first connecting frame 6, and a second connecting frame 7 is connected to the telescopic end. The second connecting frame 7 is located inside the first connecting frame 6 and is hinged to the first connecting frame 6 through a hinge pin 8. The first connecting frame 6 is provided with a guide limiting slot 9. The second connecting frame 7 is provided with a guide groove inside.

[0050] The locking structure 4 includes a support 400 and a locking rod 401 disposed in the second connecting frame 7; a second elastic element 402 is provided between the support 400 and the locking rod 401; the support 400 is provided with a through hole, and a first pull wire 501 passes through the through hole and connects to the locking rod 401; the locking rod 401 passes through the guide groove and engages with the guide limiting groove 9.

[0051] Furthermore, the middle part of the lever 401 is provided with a connecting seat 403, the connecting seat 403 is provided with two mounting cylinders 404, and a pull wire mounting part is provided between the two mounting cylinders 404; the support 400 is provided with a horizontal mounting surface; the two ends of the second elastic member 402 are respectively connected to the mounting cylinders 404 and the horizontal mounting surface.

[0052] The first pull wire 501 is connected to the pull wire mounting part.

[0053] Furthermore, the support 400 has guide holes at both ends, and the connecting seat 403 has guide rods 405 passing through the guide holes at both ends; the guide limiting groove 9 includes a horizontal locking port 900, a vertical locking port 901, and an arc guide groove 902, the two ends of the arc guide groove 902 are connected to the horizontal locking port 900 and the vertical locking port 901; the included angle between the horizontal locking port 900 and the vertical locking port 901 is ninety degrees; the guide groove extends along the extension direction of the extension end, and the maximum deformation of the first elastic element is greater than or equal to the length of the guide groove.

[0054] The above structure details the specific cooperation between the locking lever 401 and the corresponding guide limit slot 9 during the locking and unlocking process of the guardrail 3. Furthermore, the above structure does not employ complex components or require sensors or other precision parts; its simple and practical design allows for unlocking with the press of a single button, facilitating storage and user convenience.

[0055] In some preferred embodiments, the telescopic structure 1 corresponding to the locking structure 4 described above is:

[0056] The fixed slide rail 100 is used to fix the bottom of the lower berth board 2, and each end of the fixed slide rail 100 is provided with a stop block; two locking holes 107 are provided on both ends of the fixed slide rail 100 and between the two stop blocks; the stop blocks are used to cooperate with the U-shaped moving slide rail 101 and the locking plate 103 to limit the maximum movement distance of the U-shaped moving slide rail 101, and because the locking holes 107 are set and engage with the locking plate 103, the starting point and the ending point of the movement path are restricted.

[0057] The U-shaped movable slide rail 101 is slidably mounted on the fixed slide rail 100 and has an accommodating space between it and the fixed slide rail 100. An inner plate 102 is provided in the accommodating space and is connected to the U-shaped movable slide rail 101. One end of the inner plate 102 extends out from the U-shaped movable slide rail 101 to form a telescopic end.

[0058] The locking plate 103 has one end connected to the U-shaped movable slide rail 101 via an elastic hinge 104; the other end of the locking plate 103 is provided with a bent part, which is engaged in the locking hole 107; the locking plate 103 is provided with a second pull wire, the second pull wire 105 is connected to the pull wire mounting part, and is coaxially connected with the first pull wire 501.

[0059] The elastic hinge 104 includes a pivot shaft located within the accommodating space, with both ends rotatably connected to the U-shaped movable slide rail 101. A torsion spring is provided on the pivot shaft. The locking plate 103 is fixedly connected to the pivot shaft. The torsion spring provides elastic force, ensuring that the locking plate 103 and the locking hole 107 can be engaged continuously when not being pulled.

[0060] The U-shaped movable slide rail 101 is equipped with a guide wheel 108 for guiding the second pull cable 105; the fixed slide rail 100 has ball bearing assemblies 106 on both sides that contact the sides of the U-shaped movable slide rail 101. The guide wheel 108 prevents the second pull cable 105 from shifting during the pulling process and facilitates the pulling of the locking plate 103.

[0061] The telescopic structure 1 described above is a special telescopic structure designed to work in conjunction with the locking structure 4 described above. Utilizing the pulling action of the first pull cable 501 and the button, a corresponding second pull cable 105 is also provided. This allows the fixed slide rail 100 and the U-shaped movable slide rail 101 to move relative to each other after the unlocking component 5 is unlocked, thus enabling one button to control the state of both structures. The telescopic structure 1 described above does not employ common telescopic structures driven by electricity, pneumatic pressure, or hydraulic pressure, nor does it use common telescopic structures such as lead screws. It provides a certain guiding function during telescopic movement and works in conjunction with the operation of the unlocking component 5 and the locking structure 4.

[0062] Of course, this application also has another telescopic structure 1, which includes an electric telescopic rod or a lead screw telescopic structure, and a controller and a power supply connected to the electric telescopic rod or lead screw telescopic structure; the unlocking component 5 also includes a pressure sensor disposed in the mounting groove, the pressure sensor being connected to the controller and the power supply; the controller controls the telescopic length of the telescopic structure 1 according to the pressure value detected by the pressure sensor.

[0063] This application also proposes a vehicle comprising: the above-mentioned concealed lower berth guardrail device.

[0064] The concealed lower berth guardrail device is generally composed of an EPP berth board (lower berth board 2), a telescopic structure 1, a guardrail 3, a locking structure 4, an unlocking component 5, a first connecting frame 6, a second connecting frame 7, and a hinge pin 8. The fixed slide rail 100 is fixed to the EPP berth board with countersunk screws, and the EPP berth board has an installation space for accommodating it.

[0065] In the initial state, neither the first pull wire 501 nor the second pull wire 105 is subjected to external force. Due to the elastic force, the second elastic element 402 will press against the locking rod 401 and be locked in the horizontal locking port 900. At this time, the guardrail 3 cannot rotate. In addition, the elastic hinge 104 will not be rotated, and the locking plate 103 will not disengage from the locking hole 107.

[0066] The unlocking principle is as follows: When the oval unlocking button on the guardrail 3 is pressed, the first elastic element is compressed, causing the first pull cable 501 to move. This stretches the second elastic element 402, allowing the locking rod 401 to disengage from the horizontal locking port 900. During continued movement, the locking rod 401 enters the arc-shaped guide groove 902, allowing the first connecting frame 6 to rotate relative to the second connecting frame 7, thus enabling the guardrail 3 to rotate. During rotation, the locking rod 401 moves as a guide, eventually entering the vertical locking port 901. At this point, the first pull cable 501 is released, and under the action of the second elastic element 402, it stably engages with the vertical locking port 901. Therefore, after the guardrail 3 transitions from a horizontal to a vertical state, it will not rotate.

[0067] During the process of the first pull cable 501 unlocking the latch 401, the second pull cable 105 is also stretched, thereby causing the locking plate 103 to rotate via the elastic hinge 104, separating the locking plate 103 from the locking hole 107. When the second pull cable 105 is no longer pulled, it springs back under the action of the elastic hinge 104 and can re-engage with the locking hole 107.

[0068] Similarly, when the guardrail 3 is to be retracted, press the oval unlock button on the guardrail 3. The first pull cable 501 will cause the locking rod 401 to disengage from the vertical locking slot. The first connecting frame 6 and the second connecting frame 7 can rotate, and the locking rod 401 will enter the arc guide groove 902. Then, the above operations are performed in reverse, so that the guardrail 3 can change from a vertical state to a horizontal state.

[0069] Once the above process is completed, pressing an unlock button will unlock both the guardrail 3 and the telescopic structure 1, making them easy to use.

[0070] The vehicles can be either gasoline-powered cars or new energy vehicles, such as electric cars. They can also be used on high-speed trains and railway sleeper berths.

[0071] The principle of this application:

[0072] When the oval unlock button on the guardrail 3 is pressed, the first elastic element is compressed, causing the first pull cable 501 to move. This stretches the second elastic element 402, allowing the locking rod 401 to disengage from the horizontal locking port 900. As it continues to move, the locking rod 401 enters the arc-shaped guide groove 902, allowing the first connecting frame 6 to rotate relative to the second connecting frame 7, thus enabling the guardrail 3 to rotate. During rotation, the locking rod 401 moves as a guide, eventually entering the vertical locking port 901. At this point, the first pull cable 501 is released, and the guardrail 3 is stably engaged with the vertical locking port 901 under the action of the second elastic element 402. Therefore, after the guardrail 3 transitions from a horizontal to a vertical position, it will not rotate.

[0073] During the process of the first pull cable 501 unlocking the latch 401, the second pull cable 105 is also stretched, thereby causing the locking plate 103 to rotate via the elastic hinge 104, separating the locking plate 103 from the locking hole 107. When the second pull cable 105 is no longer pulled, it springs back under the action of the elastic hinge 104 and can re-engage with the locking hole 107.

[0074] Similarly, when the guardrail 3 is to be retracted, press the oval unlock button on the guardrail 3. The first pull cable 501 will cause the locking rod 401 to disengage from the vertical locking slot. The first connecting frame 6 and the second connecting frame 7 can rotate, and the locking rod 401 will enter the arc guide groove 902. Then, the above operations are performed in reverse, so that the guardrail 3 can change from a vertical state to a horizontal state.

[0075] This solves the problem in related technologies where the lower berth safety protection device is directly and rigidly fixed and cannot be retracted, resulting in poor convenience when entering and exiting the lower berth and the inability to sit in the middle section of the lower berth. Furthermore, pressing an unlock button unlocks both the guardrail 3 and the telescopic structure 1, thus facilitating use.
