A wire mounting portion is provided between the two mounting cylinders 404. A horizontal mounting surface is provided on the support 400. The two ends of the second elastic member 402 are respectively connected to the mounting cylinder 404 and the horizontal mounting surface.

[0053] The first pull wire 501 is connected to the pull wire installation portion.

[0054] Furthermore, guide holes are provided at both ends of the support 400, and guide rods 405 passing through the guide holes are provided at both ends of the connecting seat 403; the guide limit slot 9 includes a horizontal locking port 900, a vertical locking port 901 and an arc guide groove 902, and the two ends of the arc guide groove 902 are connected to the horizontal locking port 900 and the vertical locking port 901; the angle between the horizontal locking port 900 and the vertical locking port 901 is ninety degrees; the guide groove extends along the telescopic direction of the telescopic end, and the maximum deformation of the first elastic member is greater than or equal to the length of the guide groove.

[0055] The above structure specifically illustrates the specific coordination between the latching rod 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 structures, requiring no precision components such as sensors. Its simple and practical structure allows for unlocking with the push of a button, making it easy to store and convenient for use.

[0056] In some preferred embodiments, the telescopic structure 1 corresponding to the above-mentioned locking structure 4 is:

[0057] The fixed slide rail 100 is used to be fixed on the bottom of the lower berth board 2, and has a stop block at both ends; 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 movable slide rail 101 and the locking plate 103 to limit the maximum moving distance of the U-shaped movable slide rail 101, and since the setting of the locking hole 107 is engaged with the locking plate 103, the starting point and end point of the moving path are restricted.

[0058] A U-shaped movable rail 101 is slidably mounted on the fixed rail 100, with a receiving space defined between the rail and the fixed rail 100. An inner plate 102 is provided within the receiving space and connected to the U-shaped movable rail 101. One end of the inner plate 102 extends from the U-shaped movable rail 101 to form a telescopic end.

[0059] The locking plate 103 has one end connected to the U-shaped movable slide rail 101 through an elastic hinge 104; the other end of the locking plate 103 is provided with a bending portion, which is clamped in the locking clamping hole 107; a second pull wire is provided on the locking plate 103, and the second pull wire 105 is connected to the pull wire mounting portion to be coaxially connected to the first pull wire 501.

[0060] The elastic hinge 104 includes a rotating shaft located within the housing and pivotally connected to the U-shaped movable slide rail 101 at both ends. A torsion spring is mounted on the shaft, and the locking plate 103 is fixedly connected to the shaft. The torsion spring provides an elastic force that ensures that the locking plate 103 and the locking hole 107 remain engaged when not being pulled.

[0061] A guide wheel 108 is provided inside the U-shaped movable rail 101 to guide the second pull wire 105. Ball assemblies 106 are provided on both sides of the fixed rail 100 to contact both sides of the U-shaped movable rail 101. The guide wheel 108 prevents the second pull wire 105 from deflecting during the pulling process, facilitating the pulling of the locking plate 103.

[0062] The telescopic structure 1 is a special telescopic structure that cooperates with the locking structure 4 described above. With the help of the pulling action of the first pull wire 501 and the button, a corresponding second pull wire 105 is also provided. After the unlocking member 5 is unlocked, the fixed slide rail 100 and the U-shaped movable slide rail 101 can move relative to each other, so that a single button can control the state of the two structures. The telescopic structure 1 does not use a common telescopic structure driven by electricity, air pressure or hydraulic pressure, or a common telescopic structure such as a screw. It has a certain guiding role during the telescopic process and cooperates with the operation of the unlocking member 5 and the locking structure 4.

[0063] Of course, the present application also has another telescopic structure 1, which includes an electric telescopic rod or a screw telescopic structure, and a controller and a power supply connected to the electric telescopic rod or the screw telescopic structure; the unlocking member 5 also includes a pressure sensor arranged in the installation groove, and the pressure sensor is 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.

[0064] The present application also proposes a vehicle, which includes: the above-mentioned hidden lower berth guardrail device.

[0065] The concealed lower berth guardrail assembly consists of an EPP berth board (lower berth board 2), a telescopic structure 1, a guardrail 3, a locking structure 4, an unlocking member 5, a first connecting frame 6, a second connecting frame 7, and a hinge 8. The fixed rail 100 is fixed to the EPP berth board with countersunk screws, and the EPP berth board is provided with an accommodating installation space.

[0066] In the initial state, the first pull wire 501 and the second pull wire 105 are not subjected to external force. The second elastic member 402 will press the card rod 401 due to the elastic force and lock it in the horizontal locking mouth 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 card hole 107.

[0067] The unlocking mechanism is as follows: when the oval unlocking button on the guardrail 3 is pressed, the first elastic member is compressed, driving the first pull wire 501 to move, thereby stretching the second elastic member 402, allowing the latching rod 401 to disengage from the horizontal locking notch 900. As the latching rod 401 continues to move, it enters the arcuate guide groove 902, allowing the first connecting frame 6 to rotate relative to the second connecting frame 7, thus allowing the guardrail 3 to rotate. During the rotation process, the latching rod 401 moves along the guide, eventually entering the vertical locking notch 901. At this point, the first pull wire 501 is released, and the second elastic member 402 allows the latching rod 401 to engage stably with the vertical locking notch 901. As a result, after the guardrail 3 transitions from the horizontal to the vertical position, it will not rotate.

[0068] When the first pull wire 501 drives the latching lever 401 to unlock, the second pull wire 105 is also stretched, thereby driving 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 wire 105 is not pulled, it rebounds under the action of the elastic hinge 104 and can be re-engaged with the locking hole 107.

[0069] Similarly, when the guardrail 3 is to be folded up, the oval unlocking button on the guardrail 3 is pressed, and the first pull wire 501 drives the clamping rod 401 out of the vertical locking mouth; the first connecting frame 6 and the second connecting frame 7 can be rotated, and the clamping rod 401 enters the arc guide groove 902; then the above operations are performed in reverse, so that the guardrail 3 can be changed from a vertical state to a horizontal state.

[0070] The above process is completed, and the guardrail 3 and the telescopic structure 1 can be unlocked by pressing an unlocking button, thereby facilitating use.

[0071] The vehicle can be a fuel vehicle or a new energy vehicle, such as an electric vehicle. Of course, it can also be applied to high-speed trains and railway sleeper berths.

[0072] Principles of this application:

[0073] When the oval unlocking button on the guardrail 3 is pressed, the first elastic member is compressed, driving the first pull wire 501 to move, thereby stretching the second elastic member 402, allowing the latching rod 401 to disengage from the horizontal locking notch 900. As the latching rod 401 continues to move, it enters the arc guide groove 902, allowing the first connecting frame 6 to rotate relative to the second connecting frame 7, thus allowing the guardrail 3 to rotate. During the rotation process, the latching rod 401 moves and guides, eventually entering the vertical locking notch 901. At this point, the first pull wire 501 is released, and the second elastic member 402 causes the latching rod 401 to engage stably with the vertical locking notch 901. As a result, after the guardrail 3 transitions from the horizontal state to the vertical state, it will not rotate.

[0074] When the first pull wire 501 drives the latching lever 401 to unlock, the second pull wire 105 is also stretched, thereby driving 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 wire 105 is not pulled, it rebounds under the action of the elastic hinge 104 and can be re-engaged with the locking hole 107.

[0075] Similarly, when the guardrail 3 is to be folded up, the oval unlocking button on the guardrail 3 is pressed, and the first pull wire 501 drives the clamping rod 401 out of the vertical locking mouth; the first connecting frame 6 and the second connecting frame 7 can be rotated, and the clamping rod 401 enters the arc guide groove 902; then the above operations are performed in reverse, so that the guardrail 3 can be changed from a vertical state to a horizontal state.

[0076] This solves the problem in the related art that the lower berth safety protection device is directly 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 passengers. In addition, by pressing an unlocking button, the guardrail 3 and the telescopic structure 1 can be unlocked, thereby facilitating use.
