Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0035] Such as figure 1 , Figure 2a , Figure 2b Figure 2c The shown composite battery trolley includes a tray 1 and a pulley assembly 2; the tray 1 includes an upwardly opening accommodating chamber 11 for placing the battery; the pulley assembly 2 includes a pulley support structure 21 and a wheel body that is rotatably connected to the pulley support structure 21 22. The pulley support structure 21 is partly or entirely located outside the tray 1, and is used to provide an installation position for the wheel body 22. The pulley assembly 2 is rolled on the guide rail in the battery box; the tray 1 and the pulley support structure 21 are composite material struc...

Abstract

The invention relates to the technical field of rail transit, in particular to a composite material storage battery trolley, which comprises a tray and a pulley assembly. The tray comprises a containing cavity with an upward opening and is used for containing a storage battery. The pulley assembly comprises a pulley supporting structure and a pulley body rotationally connected with the pulley supporting structure, the pulley supporting structure is partially or completely located on the outer side of the tray and used for providing an installation position for the pulley body, and the pulley assembly is arranged on a guide rail in the storage battery box in a rolling mode; the tray and the pulley supporting structure are both made of a composite material structure. The storage battery trolley is made of a composite material instead of a metal material, light weight of the storage battery trolley is realized, the tray containing cavity provides stable support for the storage battery pack, and the pulley supporting structure provides a stable mounting structure for the pulley body. Meanwhile, the invention further discloses a manufacturing method of the composite material storage battery trolley, and the manufacturing method has the same technical effect.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a composite material storage battery trolley and a manufacturing method thereof. Background technique [0002] The battery pack is an important equipment in the auxiliary power supply system of the train and is installed at the bottom of the carriage. Usually, the battery trolley is set up with the battery box. In the prior art, the battery trolley is made of stainless steel, including the trolley body, frame and pulley assembly. The weight of the above structure and the built-in battery pack is about 850kg, which increases the load of the hanging equipment at the bottom of the carriage. With the continuous improvement of train speed and the strengthening of energy conservation and environmental protection awareness, the light weight of the motor car structure is required. Therefore, how to reduce the weight of the battery trolley is a technical problem that those skilled in...
