Body structure of full-bearing coach

Abstract

The invention discloses a body structure of a full-bearing coach, relates to a coach and provides the body structure of the full-bearing coach, which can improve rollover safety of a vehicle and improve the utilization rate of internal space of the vehicle. The body structure comprises a skeleton, a top cover, a side coaming, floors, windows, a safety skylight and seats, wherein the top cover is arranged at the top of the skeleton; the side coaming is arranged around the skeleton; the floors are arranged at the bottom of the skeleton; the windows are arranged on the lateral surfaces of the skeleton; the safety skylight is arranged on the top cover. The body structure is characterized in that the skeleton adopts an integrated frame structure; the skeleton is provided with transverse ring frames distributed at intervals in the longitudinal direction; an independent passenger region is formed between each two transverse ring frames; the seats in each passenger region are oppositely arranged; a transverse passage is arranged in each passenger region; a passenger get-on and get-off door is arranged on the lateral surface of each passenger region; the region at the lower part of the rear end of the skeleton is an installing bin of an engine, an air conditioning compressor and a muffler; a water tank air inlet and an air conditioning air-inlet grille are arranged on the side coaming at the rear part of the skeleton; an air outlet is formed in a rear coaming of the skeleton; the front part of the skeleton is a driving region.

Description

technical field [0001] The invention relates to a passenger car, in particular to a body structure of a full-loaded coach. Background technique [0002] A large passenger car refers to a passenger car with an approved number of passengers greater than or equal to 20. The transportation distance of a large passenger car is as high as hundreds of kilometers. Some cars have all seats; And there are luggage racks or luggage compartments for storing passengers' carry-on luggage. [0003] The fully load-bearing body structure can be vividly called the "birdcage structure". The integrated frame structure technology that has been used in the aircraft manufacturing industry before can obtain the optimal unit mass strength and reduce the structural mass. The full-carrying passenger car technology is a relatively safe and lightweight approach. [0004] The collision safety of passenger cars mainly refers to the safety of rollover structure and the safety of frontal collision. To imp...

AI Technical Summary

Problems solved by technology

The restrictions of various laws and regulations have restricted the development of conventional passenger cars to a certain extent.

[0006] The current full load bus body structure has only one connected passenger area, the seats are all arranged in the same direction, and a longitudinal passage is set in the middle, which has obvious safety hazards: for example, large-scale safety accidents frequently occur on large buses, causing heavy casualties. Local public security and traffic management departments have adopted various measures to restrict the operation of buses, all of which point to the poor safety of the rollover structure of buses, the poor air quality inside the vehicle, the low utilization rate of the interior space of the vehicle, and too few escape exits in the event of an accident. The layout of the passenger area is likely to cause the entire compartment to catch fire quickly after a fire occurs.
