AI Technical Summary
The existing battery trolley cannot be fully pulled out of the battery box, which makes maintenance and repair operations inconvenient.
A battery box designed for easy maintenance is adopted, which adopts a folding guide rail and extension structure. The folding guide rail is opened by a flip door to facilitate the pulling out of the battery trolley. A buffer pad is set at the outer end of the extension to prevent impact. A limiting member is used to fix the movable rod. The support guide rail cooperates with the folding guide rail to stabilize the pulling out.
This allows the battery trolley to be completely pulled out of the battery box, simplifying the maintenance and repair process and improving operational convenience.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-speed train battery technology, and in particular to a battery box that is easy to maintain. Background Technology
[0002] The power supply system, as one of the most important sub-equipment of a subway train, provides power for emergency lighting, ventilation, emergency displays, maintenance, communication and control, and emergency traction. The battery box structure consists of individual battery cells placed in a wheeled trolley, which is then installed in the battery casing. The entire battery box is finally installed at the bottom of the subway car body. For battery maintenance, the wheeled battery trolley must be pulled out of the battery casing. Currently, most existing battery boxes have a problem where the battery trolley cannot be pulled out completely, leading to inconvenience in maintenance and repair operations.
[0003] Therefore, it is necessary to design a battery box that is easy to maintain to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the problem in existing battery boxes where the battery trolley cannot be fully pulled out of the battery box, resulting in inconvenience in maintenance and repair operations. This invention proposes a battery box that is easier to maintain.
[0005] The technical solution of this utility model is: a battery box that is easy to maintain, including a battery box body; a flip-top door is provided on the outside of the battery box body; a battery trolley that can be pulled out from the flip-top door is provided inside the battery box body; a folding guide rail that can be opened outward is provided at the flip-top door of the battery box body, and the battery trolley can be pulled out from the folding guide rail when the folding guide rail is opened; an extension for adjusting the length of the folding guide rail is provided at the outer end of the folding guide rail.
[0006] The battery box is symmetrically provided with support rails at both ends, perpendicular to the flip door; the battery trolley is provided with rollers at both ends that cooperate with the two support rails.
[0007] The inner end of the folding guide rail is hinged to the outer end of the supporting guide rail, and when the folding guide rail is opened, it is on the same straight line as the supporting guide rail.
[0008] The extension includes a movable rod that slides into the folding guide rail; the top of the folding guide rail has a long through hole along its length; and one end of the movable rod that extends into the folding guide rail is provided with a limiting member to prevent the movable rod from disengaging from the folding guide rail.
[0009] The outer end of the extension is fixed with a buffer pad by a mounting bracket.
[0010] The limiting component is a limiting screw located in the through hole; the limiting screw is threadedly connected to the movable rod.
[0011] Both the folding guide rail and the extension are made of stainless steel.
[0012] By adopting the above technical solution, this utility model has the following beneficial effects: This utility model is provided with a folding guide rail and an extension at the outer end of the folding guide rail, so that when maintaining and repairing the battery in the battery box, the battery trolley can be completely pulled out of the battery box, thereby solving the problem of inconvenient maintenance and repair.

[0018] (Example 1)
[0019] See Figure 1 and Figure 2 This embodiment provides a battery box that is easy to maintain, including a battery box body 1; the battery box body 1 has a flip door on its outer side; the battery box body 1 has a battery trolley 2 that can be pulled out from the flip door; the flip door of the battery box body 1 is provided with a folding guide rail 3 that can be opened outwards, and when the folding guide rail 3 is opened, the battery trolley 2 can be pulled out from the folding guide rail 3; the outer end of the folding guide rail 3 is provided with an extension part 4 for adjusting the length of the folding guide rail 3.
[0020] Furthermore, to facilitate the pulling out of the battery trolley 2, the battery box 1 is provided with symmetrical support rails 5 perpendicular to the flip door at both ends; the battery trolley 2 is provided with rollers at both ends that cooperate with the two support rails 5, making it easier to pull out the battery trolley 2.
[0021] Furthermore, to facilitate the installation of the folding guide rail 3, the inner end of the folding guide rail 3 is hinged to the outer end of the support guide rail 5, and when the folding guide rail 3 is opened, it is on the same straight line as the support guide rail 5, thereby ensuring that the battery trolley 2 can be pulled out stably.
[0022] Furthermore, in order to simplify the structure of the extension 4, the extension 4 includes a movable rod that slides into the folding guide rail 3; the top of the folding guide rail 3 is provided with a long through hole along the length direction; and a limiting member 6 is provided on one end of the movable rod that extends into the folding guide rail 3 to prevent the movable rod from disengaging from the folding guide rail 3.
[0023] Furthermore, in order to reduce the impact between the battery trolley 2 and the extension 4, a buffer pad 7 is fixed to the outer end of the extension 4 by a mounting bracket, and the buffer pad 7 is preferably made of rubber.
[0024] Furthermore, to facilitate the installation of the limiting member 6, the limiting member 6 is a limiting screw located in the through hole; the limiting screw is threadedly connected to the movable rod.
