Abstract

The invention discloses an electric control springboard type rear cabin door structure and belongs to the technical field of armored vehicles. According to the electric control springboard type rear cabin door structure, the opening mode of a rear cabin door is changed, quick opening and closing are achieved, and the sealing effect is good. The rear cabin door structure comprises a door body and seal assembly, a power mechanism, a locking mechanism and a control device, inflatable type sealing adhesive tapes are adopted for door body sealing, and the conditions such as lax sealing caused by vehicle body deformation and the like can be effectively improved. A door body is of a springboard type opening structure, electric cylinder driving and the electric locking mechanism are adopted, automatic opening and closing functions are achieved, and the electric control springboard type rear cabin door structure can be better adaptable to the door body requirements of the multi-purpose armored vehicles.

Description

technical field

[0001] The invention belongs to the technical field of armored vehicles and relates to rear hatches of all armored vehicles. Background technique

[0002] With the continuous development of armored vehicle technology, the protection, mobility, and environmental adaptability of tracked armored vehicles have been continuously improved. The comprehensive performance of aspects also puts forward higher requirements.

[0003] At present, domestic mainstream armored vehicles, such as Type 99 tanks and Type 04A tracked infantry fighting vehicles, have a rear hatch made of steel and opened on one side at the rear of the vehicle. This rear hatch is manually operated and does not have the function of automatic opening and closing. Due to the unpredictability of the battlefield and the use environment, it may cause problems such as difficulty in opening the door or the inability of personnel to get out of the vehicle after opening; the springboard rear hatch that has b...
