Description

Technical Field

[0001] The present invention relates to the technical field of mobile cabin equipment, and particularly to a mobile cabin that can be bilaterally expanded. Background Art

[0002] The width of traditional mobile cabins is restricted by the width of transport vehicles, and their designs are often limited to fixed styles and space utilization modes, resulting in relatively small usable space inside the mobile cabins, which limits the usage functions of the mobile cabins. To ensure that the mobile cabin has a relatively large internal space during use and can be conveniently transported during transportation and transfer, the mobile cabin needs to have the function of morphological expansion and change. For an existing bilaterally expandable mobile cabin, there is a lack of auxiliary support structures on both sides of the mobile cabin after expansion, resulting in low support stability and strength on both sides of the mobile cabin after expansion, reducing the service life and usage safety of the mobile cabin.

[0003] For example, a expandable standard mobile cabin with the publication number CN116265670A includes a mobile cabin main body and multi-stage expansion plates inside the mobile cabin main body; the mobile cabin main body includes a base and a housing. The base includes a bottom plate and end plates at both front and rear ends of the bottom plate. The housing includes side plates that are attached to both sides of the bottom plate and can move outward horizontally, and a top plate that is located between the end plates and can rise. A folding top plate is stacked on the top wall of the top plate, and the head and tail ends of the folding top plate are respectively hinged to the side walls of the top plate and the tops of the side plates. A folding bottom plate is stacked on the inner wall of the side plate, and the head and tail ends of the folding bottom plate are respectively hinged to the side walls of the bottom plate and the bottoms of the side plates; the multi-stage expansion plates are rotatably connected to both sides of the end plates through rotating shafts, and after the multi-stage expansion plates are gradually unfolded, they can fill the gap between the housing and the end plates. However, after the side plates of this device are expanded outward, the extended bottom plate lacks corresponding support structures, and the support stability and strength are not high, resulting in a relatively large pressure on the bottom plate, which is more likely to be damaged after long-term use, reducing the service life and usage safety of the mobile cabin.

[0004] Therefore, a mobile cabin that can be bilaterally expanded is proposed to solve the above-mentioned problems. Summary of the Invention

Due to the optimization of the device structure, corresponding logistics costs can be saved during transportation and the transportation burden can be reduced;

[0031] 2. A reinforcing assembly is provided. When the pushing sleeve moves and unfolds, the two lateral pushing sleeves drive the connecting rod to slide inside the auxiliary groove, and the connecting rod will also slide on the outside of the fixed rod. The movement of the connecting rod drives the auxiliary rod to move. At this time, the fixed rod blocks the card block, so that the card block will not pop out from the inner groove, nor will it block the sliding of the auxiliary rod, until the auxiliary rod drives the card block to slide out of the outside of the cabin, and the elastic force of the spring drives the card block to pop out.

[0050] An unfolding assembly 6 is arranged below the interior of the installation box 5. The unfolding assembly 6 includes a driving motor 61 and a speed reducer 62 fixedly installed inside the installation box 5. The output end of the driving motor 61 is connected to the inlet end of the speed reducer 62. The output end of the speed reducer 62 is fixedly connected with a vertical shaft 63. One end of the vertical shaft 63 far from the speed reducer 62 passes through the installation box 5 and the cabin body 1 and is fixedly connected with a main bevel gear 64. A transverse groove 65 and a longitudinal groove 613 are formed inside the cabin body 1.

[0051] One side of the interior of the transverse groove 65 is rotatably connected with a main synchronous pulley 66. One side of the main synchronous pulley 66 close to the driving motor 61 is fixedly connected with a transverse shaft 67. One end of the transverse shaft 67 far from the main synchronous pulley 66 is fixedly connected with a driven bevel gear 68.

One side of the pushing sleeve 614 far from the driven synchronous pulley 69 is fixedly connected with the lower part of the fitting plate 4. A limiting block 616 is fixedly connected to the bottom of the pushing sleeve 614.

The driven synchronous pulley 69 drives the adjusting screw rod 610 to rotate. The limit block 616 slides inside the limit groove 615 to limit the pushing sleeve 614. The thread directions of the adjusting screw rods 610 on both sides of the driven synchronous pulley 69 are opposite. When the adjusting screw rod 610 rotates, the pushing sleeves 614 on both sides of the driven synchronous pulley 69 move away from each other. The pushing sleeve 614 slides inside the longitudinal groove 613 and drives the fitting plate 4 to expand. The fitting plate 4 drives the side box body 3 to slide out from inside the side groove 10, causing the side box body 3 to unfold. The side box body 3 drives the left bed body 8 and the right bed body 9 to separate, thereby expanding the space.

[0056] Below the interior of the cabin body 1, a strengthening component 7 is provided. The strengthening component 7 includes auxiliary grooves 71 symmetrically opened inside the cabin body 1.
