Description

Compartment body high-strength combined anti-collision structure

Technical Field

The utility model relates to an automobile compartment technical field specifically is a railway carriage or compartment body high strength combination formula anticollision structure.

Background

The existing refrigeration and heat preservation automobile generally has the problem that a first failure mode is that a rear door frame is deformed and damaged by collision, so that the whole compartment is sealed and loses efficacy, water enters the compartment and the temperature in the compartment does not reach the temperature required by refrigeration of goods, the problem that the carried goods are damaged by bubbles or are damaged by heating is caused, and the goods are lost. Especially vaccine drugs, are not only lost after being out of service, but also can endanger the life safety of human beings. Through analyzing the rear door frame connecting structure which is generally adopted at present, four frames of the rear door frame are connected with a bottom plate, side plates and a top plate of the refrigeration compartment by using rivets or bolts. Because of back door hinge seat and door frame spiro union, can't laminate between back door frame and each sideboard, there is certain clearance. The thickness of the frame of the rear door frame is between 1.5 and 2.0 mm. The impact strength of the rear door frame only depends on the structure and the material thickness of the rear door frame and the riveting strength of the rivet and the side plate. When a vehicle reversely runs into the refrigeration house opening to load and unload goods, the rear end of the carriage body needs to be close to the loading and unloading platform of the refrigeration house opening, and a driver cannot accurately master the distance between the carriage body and the loading and unloading platform, so that the door frame at the rear end of the carriage body impacts the loading and unloading platform, and the lower end of the door frame is deformed and damaged by impact. After the rear door frame is deformed and damaged, the whole compartment is sealed and fails, external heat easily enters due to sealing failure, and the oil consumption of a vehicle is increased due to the fact that the refrigerating unit works for a long time for maintaining the set temperature. Therefore, a collision-proof structure for a compartment body is urgently needed to solve the technical problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model aims at providing a railway carriage or compartment body high strength combination formula anticollision structure.

Furthermore, the bottom plate assembly sequentially comprises a glass fiber reinforced plastic layer, a composite plate layer, a hard polyurethane layer and a glass fiber reinforced plastic layer from top to bottom.

Further, the horizontal part of the L-shaped bracket is fixed between the rigid polyurethane layer and the glass fiber reinforced plastic layer.

Further, a vertical composite board layer covering the end part of the bottom plate assembly is fixed on the upper surface of the horizontal part of the L-shaped bracket.

Further, the top of the vertical composite board layer is fixedly connected with the horizontal composite board layer through a connecting steel plate.

Further, the S-shaped cross beam is fixedly connected with the bottom of the bottom plate assembly through bolts.

Through the setting, the utility model discloses a bottom plate assembly passes through L type support fixed connection with the back door frame, and the bottom plate assembly has the composite construction that the multilayer is constituteed, and the structure at cooperation border promotes back door frame crashproof intensity, solves cold-stored heat preservation railway carriage or compartment back door frame deformation damage problem, and goods safety in the protection railway carriage or compartment reduces the vehicle oil consumption, and in addition, through experimental, this structure compares original back door frame crashproof intensity under the same effort condition and can promote ten times more.
