[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5, a mounting structure for a semi-enclosed berth for a rail vehicle, comprising a U-shaped plate 1, a berth body 2, a self-locking device and an auxiliary fastening device, wherein the berth body 2 is mounted in the U-shaped plate 1 through the self-locking device, a mat 3 is mounted on the top of the berth body 2, and a barrier 4 is mounted on the top end of the berth body 2 away from the U-shaped plate 1, the self-locking device comprises a locking box 5, a mounting block 6, a mounting groove 7, a self-locking groove 8, a self-locking block 9, a square groove 10, a shift block 11, a shift groove 12 and a spring 13, the side wall of the U-shaped plate 1 is embedded with the mounting block 6, the side wall of the berth body 2 is provided with a mounting groove 7, the mounting block 6 is adapted to the mounting groove 7, the bottom wall of the berth body 2 is fixedly installed with the locking box 5, and the locking box 5 is provided with the square groove 10 running through the upper and lower parts, and the self-locking block 9 is movably installed in the square groove 10, the bottom wall of the berth body 2 is provided with a through groove running through the mounting groove 7, and the bottom wall of the mounting block 6 is provided with a self-locking groove 8, and the self-locking block 9 passes through the through groove and is adapted to the self-locking groove 8, and the end of the self-locking block 9 close to the U-shaped plate 1 is a bevel design, and the left and right ends of the square groove 10 are provided with the shifting groove 12, and the left and right ends of the self-locking block 9 are fixedly installed with the shifting block 11, The block 11 is slidably connected to the shifting groove 12, and the spring 13 is installed at the bottom end of the shifting block 11 in the shifting groove 12. The two ends of the bottom wall of the berth body 2 are assisted and fixed to the U-shaped plate 1 through the auxiliary fastening device. In this embodiment, when in use, when the berth body 2 needs to be installed to the inner wall of the U-shaped plate 1 (the U-shaped plate 1 is a carriage wall with a U-shaped design), the mounting groove 7 on the side wall of the berth body 2 is aligned with the mounting block 6 on the U-shaped plate 1, and then the berth body 2 is pushed to make the mounting block 6 enter the mounting groove 7. Since one end of the self-locking block 9 is designed as a slope, when the berth body 2 is pushed in, the slope on the self-locking block 9 will contact the mounting groove 7. The mounting block 6 forces the self-locking block 9 to move inward in the square groove 10 and compresses the spring 13. The mounting block 6 continues to move toward the mounting groove 7. When the self-locking block 9 corresponds to the self-locking groove 8, the elastic force of the spring 13 will push the moving block 11 to drive the self-locking block 9 to move outward until the self-locking block 9 is completely locked in the self-locking groove 8 and the mounting block 6 enters the mounting groove 7. At this time, the berth body 2 is stably installed on the U-shaped plate 1. Finally, use an auxiliary fastening device to auxiliary fix the two ends of the bottom wall of the berth body 2 to the U-shaped plate 1 to ensure the firmness and stability of the installation. The installation of the U-shaped plate 1 and the berth body 2 forms a semi-enclosed structure of the berth body 2.

[0027] The bottom wall of the chute 17 is provided with a through hole 20 corresponding to the position of the screw hole 18, and the bolt 19 passes through the through hole 20 and is threadedly connected to the screw hole 18. The fixed connection between the support plate 15 and the U-shaped plate 1 fixes the cross plate 14 to the bottom end of the berth body 2, and the U-shaped plate 1 is fixed to the bottom end of the berth body 2. When the profile 1 is installed with the berth body 2, the slider 16 at the bottom end of the berth body 2 slides with the slide groove 17 on the cross plate 14 to guide the push of the berth body 2, which can ensure that the berth body 2 moves quickly to the target position. The sliding connection design of the slider 16 and the slide groove 17 makes the berth body 2 have a certain adjustment flexibility during installation. After sliding to the target position and aligning with the through hole 20 in the slide groove 17, the bolt 19 is passed through the through hole 20 and threadedly connected to the screw hole 18 to connect the slider 16 with the cross plate 14, which can ensure that the berth body 2 will not loosen or fall off after being fixed, thereby improving the stability and reliability of the entire installation structure. Through the design of the cross plate 14 and the support plate 15, additional support is provided for the bottom of the berth body 2. This support structure can effectively prevent the berth body 2 from shaking or shifting during use, thereby increasing the comfort and safety of passengers.

[0028] During actual use, the connection strength between the cross plate 14 and the support plate 15 is further strengthened. In this embodiment, a reinforcing rod 21 is installed between the end of the cross plate 14 away from the U-shaped plate 1 and the lower part of the support plate 15. The reinforcing rod 21 can effectively resist deformation or displacement caused by external forces, thereby ensuring that the connection between the cross plate 14 and the support plate 15 is more stable. The reinforcing rod 21 increases the force-bearing area of ​​the entire structure, so that the connection between the cross plate 14 and the support plate 15 can withstand a greater load. The two sets of self-locking devices work together to significantly improve the installation strength of the berth body 2. Even if one set of devices has a minor fault or fails in some cases, the other set of devices can still maintain stable installation, thereby improving the fault tolerance of the device.

[0029] During actual use, in order to further improve the installation stability of the berth body 2, in this embodiment, two groups of self-locking devices are provided and are symmetrically designed. The two groups of symmetrically designed self-locking devices can ensure that the berth body 2 is subjected to uniform force during installation, thereby avoiding unstable installation or deformation caused by uneven force.

[0030] During actual use, it is further convenient to pull the self-locking block 9 and two groups of self-locking blocks 9 can be pulled at the same time with the help of external tools. In this embodiment, a cylindrical ring 22 is installed at the bottom end of the self-locking block 9. The cylindrical ring 22 provides a clear gripping point, allowing the operator to pull the self-locking block 9 more easily and accurately. This design reduces operational inconvenience and improves operational convenience and efficiency. The shape and design of the cylindrical ring 22 enable it to be used in conjunction with external tools, which allows the operator to use external tools to pull two or more groups of self-locking blocks 9 at the same time, greatly improving operational flexibility and efficiency.

[0031] During actual use, the anti-slip effect of the enclosure 4 is further improved. In this embodiment, the enclosure 4 is provided with anti-slip grooves, which can increase the friction between the enclosure 4 and the user and reduce the risk of accidental falls due to sliding. Especially when performing activities or turning over on the berth body 2, this anti-slip design can significantly improve the safety of the user.

[0032] During actual use, the shift block 11 is further limited. In this embodiment, the two ends of the shift groove 12 are closed. By limiting the moving range of the shift block 11, the closed shift groove 12 can prevent the shift block 11 from excessive movement or dislocation due to human error.

[0033] During actual use, the movement of the shift block 11 and the extension and contraction of the spring 13 are further guided. In this embodiment, a fixing rod 23 is installed in the shift groove 12, and the fixing rod 23 is slidingly connected to the shift block 11. The fixing rod 23 provides a clear path for the movement of the shift block 11, ensuring that the shift block 11 can slide smoothly in the shift groove 12 in a predetermined direction. This guiding effect reduces the shaking or deviation of the shift block 11 during movement, improves the stability and reliability of the device, and also guides the extension and contraction of the spring 13 to prevent the spring 13 from deflecting when it is extended and contracted.

[0034] In order to explain in detail the possible application scenarios, technical principles, specific solutions that can be implemented, and the purpose and effects of this application, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of this application and are therefore only examples and are not intended to limit the scope of protection of this application.
