Four-point synchronous cabin expansion system

Abstract

The invention discloses a four-point synchronous cabin expansion system, and belongs to the field of shelter vehicles. The system comprises a main cabin, two expansion cabins are slidably connected into the main cabin, and the opposite sides of the two expansion cabins extend to the two sides of the main cabin. Two servo motors are fixedly installed on the inner bottom wall of the main cabin body, output shafts of the two servo motors are fixedly connected with speed reducers correspondingly, output shafts of the two speed reducers are fixedly connected with transmission shafts correspondingly, and the two transmission shafts are sleeved with two gears fixedly connected with the transmission shafts correspondingly. And four movable rails are slidably connected to the bottom of the main cabin body. The two servo motors are used for driving the left movable rail and the right movable rail of the expansion system correspondingly, cabin expansion is achieved, the movable rails are connected with the expansion cabins through the two connecting points on each side, the four supporting points are arranged on the two sides, the expansion cabin and the main cabin are in lap joint, pressed and sealed, the structure is simple, the weight is low, and the load burden of the whole vehicle can be reduced.

Description

technical field [0001] The invention relates to the field of shelter vehicles, and more specifically, to a four-point synchronous cabin expansion system. Background technique [0002] Square cabins originated in the United States and were first used in the US military. They are all equipped with vehicles and have high mobility. According to different needs, corresponding structural designs are carried out inside the shelters, and relevant equipment is installed to have specific functions. It is widely used in the mobile command system of the US military, communications, medical care, and logistics support, and is one of the important equipment of the US military's mobile forces. In the 1950s and 1960s, American RVs developed unprecedentedly. During this period, related processes and structures of shelter manufacturing were also introduced, which improved the reliability and applicability of RVs. Most of the RVs we see today are vans. The material selection and structural fo...

Problems solved by technology

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a four-point synchronous cabin expansion system, which has the advantages of simple structure and light weight, and solves the problem of complex structure of the prior art expansion technology, which causes the system itself to be heavy. Occupies the weight utilization space of the whole vehicle, and the sealing effect is not very good after the shelter of the prior art is expanded
