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 present invention relates to the technical field of rail transit, and in particular to a trolley with a battery made of composite materials, including a tray and a pulley assembly; The wheel body and the pulley supporting structure are partially or completely located outside the pallet to provide an installation position for the wheel body, and the pulley assembly is rolled on the guide rail in the battery box; the pallet and the pulley supporting structure are all composite materials. By improving the material of the battery trolley from metal material to composite material, the weight of the battery trolley is realized. The setting of the tray accommodation cavity provides stable support for the battery pack, and the setting of the pulley support structure provides a stable installation structure for the wheel body. At the same time, the invention also claims a manufacturing method of a composite battery trolley, which 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...
