Description

Technical Field

[0001] This invention relates to the field of modular cabin assembly, and in particular to a modular cabin end plate sliding extension mechanism. Background Technology

[0002] The sliding extension mechanism of the cabin end plate is a support structure for assembling and folding the cabin. There are various existing extension methods and extension mechanism designs for expandable cabins, but the designs are too cumbersome. The current mainstream design uses multiple motors or multiple hydraulic rods to jointly drive the end plate to move, thereby driving the side plates or top plates to unfold for cabin assembly. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of the cabin end plate sliding extension mechanism.

[0003] Existing modular shelter end plate sliding extension mechanisms have certain drawbacks in use. Due to the complex control of multi-motor linkage and the motion interference between the hydraulic rod and the extension plate, the extension mechanism of the expandable modular shelter is too complicated, resulting in reduced reliability and increased cabin weight. The end plate of the modular shelter cannot meet the required strength and is prone to damage, which has a certain adverse effect on the actual use. Therefore, we propose a modular shelter end plate sliding extension mechanism. Summary of the Invention

[0017] (III) Beneficial Effects

[0018] Compared with existing technologies, this invention provides a sliding expansion mechanism for the end plate of a modular shelter, which has the following advantages: This sliding expansion mechanism features an arc-shaped locking end to the slide rail, applicable to all multi-dimensional expandable shelters. It provides a new design solution for the deployment of two-level and multi-level shelters. By replacing motor drive with a physical mechanism design, it solves the design pain points of current multi-dimensional expandable shelter expansion mechanisms, reducing costs while greatly improving reliability. Using a single motor and slide rail in combination, the movement of the end plate drives the side plate to unfold along the slide rail. The slide rail and side plate are in contact via pulleys, which are mounted on the side plate and connected by casters. The slide rail design of this application is key to achieving this function. The locking end of the slide rail features an arc-shaped design. When the end plate drives the side plate to fully unfold, the pulley moves to the locking end, and then the bottom plate falls. Under the limiting action of the bottom plate, the side plate and pulley lock simultaneously. When the bottom plate retracts, the end plate retracts under the drive of the motor, and the side plate pulley moves in the opposite direction along the slide rail under the action of lateral force. At this point, the retraction of the cabin can be achieved without the need for a motor or hydraulic rod to drive the pulley end of the side plate. The innovation of this application lies in the arc-shaped design of the locking end of the slide rail. With a straight or right-angle locking end, the pulley cannot slide directly in the reverse direction during end plate retraction and can only be driven by a motor or hydraulic rod. The arc-shaped design, through a clever structural design, allows the pulley to slide solely by the reverse force of the end plate. Reducing one motor lowers the cost of the cabin and the complexity of the multi-motor control system. At the same time, the mechanical structure has high reliability. The entire cabin end plate sliding extension mechanism has a simple structure, is easy to operate, and performs better than traditional methods. Attached Figure Description

It uses a single motor and a slide rail in conjunction. The movement of the end plate causes the side plates to unfold along the slide rail. The slide rail and side plates contact each other via pulleys, which are mounted on the side plates and connected by casters. The slide rail design of this application is key to achieving this function. The locking end of the slide rail adopts an arc-shaped design. When the end plate drives the side plates to fully unfold, the pulleys move to the locking end, and then the base plate falls. Under the limiting action of the base plate, the side plates and pulleys lock simultaneously. After the base plate is retracted, the end plate retracts under the drive of the motor, and the side plate pulleys move in the opposite direction along the slide rail under the action of lateral force. At this time, the side plate pulleys do not need to be driven by a motor or hydraulic rod to realize the retraction of the cabin. The innovation of this application is the arc-shaped design of the locking end of the slide rail. With a straight or right-angle locking end, the pulleys cannot slide directly in the opposite direction when the end plate is retracted, and can only be driven by a motor or hydraulic rod. The arc-shaped design, through a clever structural design, allows the pulleys to slide solely by the reverse force of the end plate. Reducing one motor not only reduces the cost of the cabin but also reduces the complexity of the multi-motor control system. At the same time, the mechanical structure has high reliability. The arc-shaped design of the locking end of the slide rail can be applied to all multi-dimensional expandable cabins, providing a new design solution for the deployment of two-level and multi-level cabins. By designing a physical mechanism to replace motor drive, it solves the design pain points of current multi-dimensional expandable cabin expansion mechanisms, reducing costs while greatly improving reliability.
