[0030] Example 1:

[0031] refer to Figures 1-6This embodiment proposes a telescopic structure applicable to telescopic houses, comprising at least two sets of parallel scissor braces 2 connected by several vertical connecting rods 25. Each scissor brace 2 includes several parallelogram-shaped scissor brace units 21. The first hinge point 22 at the top of the uppermost scissor brace unit 21 is hinged to one end of a vertical connecting rod 25. The second hinge point 23 at the bottom of the uppermost scissor brace unit 21 is slidably connected to the middle of the vertical connecting rod 25. The other end of the vertical connecting rod 25 is hinged to either the first hinge point 22 or the second hinge point 23 of the lowermost scissor brace unit 21. In this embodiment, a vertical slide rail 26 is connected to the middle of the vertical connecting rod 25. A vertical slider 27 is vertically slidably connected to the vertical slide rail 26. The vertical slider 27 is connected to the second hinge point 23 at the top of the uppermost scissor brace unit 21, allowing the second hinge point 23 to slide vertically along the vertical connecting rod 25 during extension. The telescopic house in this embodiment also includes several spaced-apart support components. Adjacent support components are connected by a telescopic structure. Each support component includes a crossbeam 1, with uprights 4 connected to both sides of the crossbeam 1. The outer sides of the uprights 4 are hinged to the third hinge point 24 at the hinge point of the adjacent scissor brace unit 21. Guide sliders 314 are connected to the bottom of the two uprights 4. The two guide sliders 314 are slidably connected to two guide rails 313. The guide sliders 314 slide on the guide rails 313 through the drive component 3. The two guide rails 313 are fixed on the two bottom rods 5. The two ends of the bottom rods 5 are connected to support columns 6, which are fixed to the ground.

[0032] At this time, the bottom scissor brace 2 drives the top scissor brace 2 to extend outward. The connection point between the top scissor brace 2 and the vertical connecting rod 25 is the first hinge point 22 and the second hinge point 23, which makes the force distribution more reasonable.

[0033] Example 2:

[0034] Continue to refer to Figures 1-6The rest is the same as in Embodiment 1, except that: in order to solve the problem of different left and right extension rates during the extension process, a drive component 3 is proposed, including a dual-axis motor 31 disposed between the two bottom rods 5. The two output shafts of the dual-axis motor 31 are respectively connected to one end of the two transmission shafts 33. In this embodiment, the output shafts of the dual-axis motor 31 and the transmission shafts 33 are connected by a cross-type universal coupling 32. The other ends of the two transmission shafts 33 are respectively connected to the first intermediate sprocket 34. One end of the bottom rod 5 is connected to the second intermediate sprocket 35. The first intermediate sprocket 34 and the second intermediate sprocket 35 are connected by an intermediate chain 311. The second intermediate sprocket 35 is synchronously connected to the first transmission sprocket 36 on one side, and the other end of the bottom rod 5 is connected to the second transmission sprocket 37. The first transmission sprocket 36 and the second transmission sprocket 37 are connected by a transmission chain 312. The slide rail is arranged parallel to the transmission sprocket, and the bottom of the upright 4 of the outermost support component is connected to the transmission chain 312.

[0035] The symmetrical connection between the two drive sprockets includes at least two sets of tensioning structures, through which the drive chain 312 passes to achieve tension. The tensioning structure includes a sliding tensioning wheel 38 and a fixed tensioning wheel 39. The bottom of the sliding tensioning wheel 38 is connected to a tensioning bolt 310, and the bottom of the tensioning bolt 310 extends out of the base rod 5. Rotating the tensioning bolt 310 can lift the sliding tensioning wheel 38 upward, causing the sliding tensioning wheel 38 to slide vertically. The drive chain 312 passes through the top of the sliding tensioning wheel 38 and the bottom of the fixed tensioning wheel 39, respectively.

[0036] Working principle:

[0037] First, the dual-axis motor 31 drives the two transmission shafts 33 to rotate, which in turn drives the central sprocket to rotate. The central sprocket drives the transmission sprocket to rotate, and the transmission sprocket drives the bottom of the outermost upright 4 to slide outward. Other support components extend outward under the action of the outermost support components and the scissor brace 2, realizing the opening and closing of the telescopic house.

[0038] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
