[0018] Preferably, a pulley is installed at the bottom of the free end of the second-stage telescopic cabin.

[0019] The beneficial effects of adopting the above technical solution are:

[0020] 1. This cabin is equipped with a telescopic cabin. The telescopic cabin consists of a first-stage telescopic cabin and a second-stage telescopic cabin. The two-stage telescopic cabin can be retracted and expanded through a stroke amplification device. The active core and the driven core in the stroke amplification device are respectively connected to the first and second telescopic cabins. When the motor inputs a stroke to the active core, the first-stage telescopic cabin is extended by one stroke through the cooperation between the gear and the rack. The second-stage telescopic cabin is extended by one stroke relative to the first-stage telescopic cabin and twice the stroke relative to the main cabin, which greatly improves the space utilization.

[0021] 2. The solar device in this cabin is equipped with a folding and unfolding mechanism. The folding and unfolding mechanism is composed of a main telescopic frame, a slider and a multi-link mechanism. When the slider rises, the multi-link mechanism will fold and retract to the middle, and when the slider descends, the multi-link mechanism will unfold. The solar panel is installed on the multi-link mechanism, thereby driving the solar panel to fold and unfold. In addition, the folding and unfolding mechanism is connected to the bottom frame through an electric push rod, and the electric push rod can adjust the angle of the folding and unfolding mechanism and the solar panel in the left and right directions by extending and shortening; the electric cylinder A rotates to connect to the bottom frame, and the electric cylinder B slides to connect to the bottom frame. The two electric cylinders can adjust the angle of the folding and unfolding mechanism and the solar panel in the front and back directions. Therefore, the solar panels in this cabin can adjust their own angles at any time according to the height of the sun, which is very practical.

[0022] 3. This cabin has a manual ratchet deployment device. The gear Z on the rotating shaft of the mechanism is meshed with the rack fixedly connected to the first-stage telescopic cabin. When the power system fails, the operator can hang the auxiliary rod into the slot on the rotating shaft, and use the auxiliary rod to turn the rotating shaft to rotate. The rotating shaft drives the gear Z to rotate, and the gear Z drives the rack to move. The rack drives the first-stage telescopic cabin to move, and the first-stage telescopic cabin drives the second-stage telescopic cabin to unfold. The auxiliary rod toggles the rotating shaft based on the lever principle, and the rotating shaft is connected to the first-stage telescopic cabin through a gear rack transmission. Therefore, it is very labor-saving to toggle the rotating shaft. At the same time, the rotating shaft is rigidly connected to the ratchet at the bottom. If the telescopic cabin moves in the opposite direction due to external force, the ratchet can jam the rotating shaft, thereby ensuring that the telescopic cabin will not cause harm to the operator when unfolded.

[0023] 4. The second-stage telescopic cabin has a pulley. The pulley is located at the bottom of the second-stage telescopic cabin and is in direct contact with the ground. When the second-stage telescopic cabin is extended, the pulley can share part of the gravity of the telescopic cabin, reduce the deformation of the telescopic cabin, and reduce the resistance when the telescopic cabin is unfolded.

[0024] 5. The shelter has two expansion modes: autonomous and manual. Autonomous expansion is to drive the telescopic cabin to expand by driving the stroke amplification device through the motor. Manual operation is to rotate the ratchet locking device and cooperate with the gear rack to drive the telescopic cabin to expand. The two expansion modes can be switched freely according to needs, which is very practical.

[0025] 6. This cabin has an ingenious structure, flexible movement, and a wide range of uses. It can not only be used as a temporary shelter, but also as a temporary dormitory, and is highly practical.

[0026] 7. This shelter has two modes: contraction and expansion. In the contraction mode, it saves space and is easy to place. In the expansion mode, the shelter has a large volume and is sturdy and reliable.

[0027] 8. This cabin is suitable for both standby and working situations. In standby state, it saves space and is easy to place and transport. In working state, the space is adjustable, with many application scenarios, a large working range and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] like Figure 1-3 As shown, the square cabin includes a main cabin 1, a telescopic cabin 2, a solar energy device 3, a stroke magnification device 4, and a manual ratchet unfolding device 5. The telescopic cabin 2 includes a fixed telescopic cabin 2-1, a first-level telescopic cabin 2-2, a second-level telescopic cabin 2-3, and a pulley 2-4. The fixed telescopic cabin 2-1 is fixedly connected to the main cabin 1, the first-level telescopic cabin 2-2 is slidably connected to the fixed telescopic cabin 2-1 through the stroke magnification device 4, and the second-level telescopic cabin 2-3 is slidably connected to the first-level telescopic cabin 2-2 through the stroke magnification device 4. Under the action of the stroke magnification device 4, the first-level telescopic cabin 2-2 and the second-level telescopic cabin 2-3 move simultaneously and the stroke of the second-level telescopic cabin 2-3 is twice the stroke of the first-level telescopic cabin 2-2. The stroke magnification device 4 is also fixedly connected to the fixed telescopic cabin 2-1.

[0060] There are two telescopic cabins 2, which are symmetrically arranged on the left and right sides of the main cabin 1. Two rollers 2-4 are installed at the bottom of the second-level telescopic cabin 2-3 to reduce the deformation of the telescopic cabin 2 and the resistance during the folding and unfolding process.

[0061] Specifically, Figure 4-8 As shown, the stroke amplification device 4 includes a housing 4-1, a driving core 4-2, a driven core 4-3, an X fixed bottom rack 4-4, a Y fixed bottom rack 4-5, an X driven top rack 4-6, a Y driven top rack 4-7, a gear X4-8, and a gear Y4-9.

[0062] The X-fixed bottom rack 4-4 and the Y-fixed bottom rack 4-5 are arranged in parallel and are both welded to the bottom of the housing 4-1, the X-driven top rack 4-6 is welded to the top of the driving core 4-2, and the Y-driven top rack 4-7 is welded to the top of the driven core 4-3. The gear Y4-9 is rotatably connected to the driving core 4-2 through a rotating shaft. The gear X4-8 is arranged between the X-fixed bottom rack 4-4 and the X-driven top rack 4-6 and meshed with them respectively, and the gear Y4-9 is arranged between the Y-fixed bottom rack 4-5 and the Y-driven top rack 4-7 and meshed with them respectively.

[0063] The outer shell 4-1 is welded and connected to fix the telescopic cabin 2-1. The driving core 4-2 and the driven core 4-3 are both connected to the outer shell 4-1 by rail sliding. The driving core 4-2 is welded and connected to the first-stage telescopic cabin 2-2, and the driven core 4-3 is welded and connected to the second-stage telescopic cabin 2-3. The motor is fixedly connected to the driving core 4-2, and the gear X4-8 is installed on the motor shaft and driven by the motor to rotate. When the gear X4-8 rolls along the X-fixed bottom rack 4-4, it drives the driving core 4-2 to slide and move, and the driving core 4-6 drives the first-stage telescopic cabin 2-2 to slide and unfold. When the first-stage telescopic cabin 2-2 completes the unfolding of a stroke, it drives the second-stage telescopic cabin 2-3 to complete the movement of a stroke. The active core 4-6 slides and moves while driving the gear Y4-9 to rotate, the gear Y4-9 drives the Y driven top rack 4-7 to move, the Y driven top rack 4-7 drives the driven core 4-3 to move, the driven core 4-3 drives the second stage telescopic cabin 2-3 to move and unfold, the second stage telescopic cabin 2-3 moves one stroke relative to the first stage telescopic cabin 2-2. Relative to the fixed telescopic cabin 2-1, the second stage telescopic cabin 2-3 moves twice the stroke.

[0072] When the folding and unfolding mechanism 3-7 is unfolded, the plate connecting rod A3-7-3, the plate connecting rod B3-7-4, and the plate connecting rod C3-7-5 are horizontally connected to form a first straight line. The auxiliary connecting rod B3-7-7 and the auxiliary connecting rod C3-7-8 are horizontally connected to form a second straight line.
