Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0024] The utility model relates to a drawable undercarriage box.

[0025] See also Figure 1-2 The pull-out undercar box includes a box body 1, and a mounting base 2, a relay disk 3 and a pull-out assembly are arranged inside the box body 1. The mounting base 2 is arranged on the inner wall of the box body, and the relay disk 3 is arranged horizontally inside the box body 1. The pull-out assembly is configured to drive the relay disk 3 to move forward and backward.

[0026] Furthermore, the box 1 is provided with at least two relay disks 3, which are arranged in parallel side by side. The relay disk 3 is designed as an upper and lower two-layer structure, which not only helps to optimize space utilization, but also can be managed according to function, making the entire layout clearer and more orderly; in addition, the layered design is also convenient for heat dissipation, reducing overheating problems caused by densely arranged components.

[0027] Demonstratively, the pull-out assembly includes a slide rail 1 4 and a slide rail 2 5, the slide rail 1 4 is arranged on the left and right sides of the relay disk 3, the slide rail 2 5 is arranged on the mounting base 2 and arranged corresponding to the slide rail 1 4, and the slide rail 2 5 is slidably connected to the slide rail 1 4.

[0028] Furthermore, the slide rail 1 4 is connected to the left and right sides of the relay disk 3, providing a stable sliding track for the relay disk; the slide rail 2 5 is correspondingly connected to the mounting frames 21 on the left and right sides of the mounting base 2, ensuring that the installation of the slide rail 2 5 is firm and stable, providing a stable support and guiding effect for the slide rail 1 4 and the relay disk 3 connected to the slide rail 1 4, and will not generate abnormal noise and vibration when the train is running.

[0029] Through the stable and reliable relative sliding of the slide rail 1 4 and the slide rail 2 5, it is possible to ensure that the relay disk 3 can achieve precise and stable linear sliding, and ensure that the relay disk can be easily pulled out or pushed in from the inside of the box when needed, thereby facilitating installation, debugging or maintenance work.

[0030] Preferably, the slide rail 1 4 is locked and connected to the relay plate 3 by bolts and nuts, and the slide rail 2 5 is locked and connected to the mounting frame by bolts and nuts. This connection method ensures that the connection between the slide rail, the relay plate and the mounting frame is tight and stable, so as to ensure that the relay plate is stable and reliable during the sliding process.

[0031] Furthermore, drag chains 6 are provided on both sides of the installation base 2. The drag chains 6 are used to store the cables of the relay panel and can move forward and backward with the relay panel.

[0032] Preferably, one end of the drag chain 6 is connected to the relay disk 3, and the other end of the drag chain 6 is bent and connected to the mounting base 2. The drag chain 6 is used to ensure that the wiring path of the relay disk is clear and orderly, and can maintain a stable connection of the cable when the relay disk is pulled out or pushed in, avoiding electrical faults caused by movement.

[0033] Furthermore, the pull-out undercarriage box further comprises a handle 7, which is arranged on the front side of the relay panel 3 near the door of the box body 1. By pushing and pulling the handle 7, the relay panel is driven to move forward and backward through the relative sliding of the slide rail 1 4 and the slide rail 2 5, and the drag chain also moves forward and backward with the relay panel. Example

The mounting base 2 and the relay disk 3 are arranged on the inner wall of the box body 1. The pull-out assembly includes a slide rail 1 4 and a slide rail 2 5. The pull-out assembly is configured to drive the relay disk 3 to move forward and backward.

[0036] The difference between this embodiment and the first embodiment is that the relay disk 3 is arranged longitudinally inside the box body 1, two relay disks 3 are arranged side by side in parallel, and the relay disk 3 is designed as a left and right two-layer structure.

[0037] Correspondingly, the slide rail 1 4 is connected to the upper and lower sides of the relay disk 3, and the slide rail 2 5 is correspondingly connected to the mounting frames 21 on the upper and lower sides of the mounting base 2. The remaining structural settings are the same as those in the first embodiment.

[0038] In summary, the internal relay disk of the pull-out undercarriage box of the utility model is arranged horizontally or vertically according to actual use requirements, and the pull-out assembly is also designed accordingly according to the arrangement direction of the relay disk.

[0039] After the handle 7 is pulled, the slide rail drives the relay plate 3 to move forward, and the drag chains 6 on both sides also move forward;

[0040] After pushing the handle 7, the slide rail drives the relay plate 3 to move backward, and the drag chains 6 on both sides also move backward and are locked after being in place.

[0041] The pull-out assembly provides a stable and reliable sliding platform for the relay panel, and the corresponding drag chain design effectively solves the problems of insufficient existing maintenance space and overly scattered layout of electrical equipment, greatly improving the utilization rate of the equipment space under the vehicle, making the entire electrical system more efficient and convenient to install, debug and maintain, bringing great convenience to maintenance personnel.
