Urban rail metro vehicle ceiling trim lifting structure

Abstract

The invention discloses an urban rail metro vehicle ceiling trim lifting structure which comprises a small ceiling piece. A lifting sectional material is connected to the position below the small ceiling piece and is integrally of a cavity structure. The cross section of the lifting sectional material is in a Z shape. C-shaped installation sliding grooves are formed in the upper portion and the lower portion of an upper cavity, the sliding groove with an upward opening is a lifting structure installation point, and the sliding groove with a downward opening is a lamp installation point. Two C-shaped installation sliding grooves with downward openings and a clamping groove are formed in the bottom of a lower cavity, the sliding groove in one end serves as a grille installation point, the sliding groove in the other end serves as a middle top installation point, and the clamping groove for insertion of a grille is further formed in the bottom layer. By the adoption of the urban rail metro vehicle ceiling trim lifting structure, a lamp middle top board, the grille and the like are directly lifted to the lifting structure without switching, and the installation process is simplified; weight is reduced, the weight of a vehicle is effectively reduced, and energy is saved; the machining amount is reduced, and machining cost is saved; and the sectional material only needs to be installed at one point in the width direction of the vehicle, and installation points can be arranged in the length direction of the vehicle according to force analysis.

Description

Technical field [0001] The invention relates to the technical field of urban rail vehicle body equipment. Background technique [0002] Nowadays, environmental protection and energy conservation policies and measures have become a familiar development trend of civilized life. With the rapid development of the urban rail transit industry, energy conservation and environmental protection as an important indicator have become the focus of subway vehicle design, and the lightweight design of vehicles is An effective way to save energy. As an important part of subway vehicles, the interior system should be designed to be lightweight. [0003] Existing technology one, such as figure 1 As shown, in some domestic urban rail vehicles, most of the ceiling interior installations are installed with a secondary skeleton structure. The secondary skeleton is a crisscross frame structure. The entire frame structure runs through the entire roof and is arranged on the entire ceiling interior. Abov...
