Problems solved by technology

[0003] At present, domestic mainstream armored vehicles, such as Type 99 tanks and Type 04A tracked infantry fighting vehicles, have a rear door made of steel and opened on one side at the rear of the vehicle. This rear door is manually operated and does not have automatic opening and closing functions. 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 been developed and applied to wheeled armored vehicles adopts a steel structure. The weight of the door body is relatively large, and it is generally driven by hydraulic pressure. There are problems such as hydraulic oil leakage, low transmission efficiency, and limited driving methods. Therefore, it is necessary to design a rear hatch that can be opened and closed quickly and reliably automatically, which is necessary for the future development of armored vehicles.

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings, but not as a limitation of the present invention.

[0028] An electric control springboard type rear cabin door mechanism of the present invention has a structure such as figure 1 As shown, it includes four parts: door body and seal 1-1, power mechanism 1-2, locking mechanism 1-3 and control device 1-4. The specific structure of each part is as follows figure 2 , 3 , 4 shown.

[0029] like figure 2 As shown, door body and seal 1-1, including inflatable sealing strip 1, rear hatch door body 2, rear hatch door frame 3, escape door sealing strip 4, escape door body 5, escape door frame 6, pivoting arm 7, Car body connecting block 8, rotating pin shaft 9, air pump mechanism 10;

[0030] like Figure 2-1 , 2-2, in order to meet the sealing requirements of the car body, the inflatable sealing strip 1 is installed in the groove of the rear door frame 3, and the rear do...

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...
