The support assembly 10 comprises at least two columns 11, each of which is arranged in two rows to form a first row support group 12 and a second row support group 13, and the first row support group 12 and the second row support group 13 support both sides of the building. The telescopic crossbeam 20 is connected to the second row of support groups 13, and the telescopic crossbeam 20 includes at least two fixed frames 21 that are sleeved in sequence, and the telescopic crossbeam 20 is extended and folded by the fixed frames 21 that are sleeved in sequence; the telescopic room beam 30 is connected to the first row of support groups, and the telescopic room beam 30 includes at least two beam bodies 31 that are sleeved in sequence, and the telescopic room beam 30 is extended and folded by the beam bodies 31 that are sleeved in sequence; the beam body 31 includes a side panel 37 arranged on one side of the beam body 31, and the side panel 37 is arranged in an arc-shaped structure; a through hole 370 is arranged in the side panel 37, and the through hole 370 is arranged in the side panel 37. The hole 370 passes through both sides of the side panel 37; the reel assembly 40 is arranged on the side of the first column support group 12 away from the second column support group 13, and the reel assembly 40 includes mounting frames 41 stacked in sequence, shells 42 respectively connected to the mounting frames 41, a rolling curtain 43 passing through the shell 42, and a rolling curtain driving member 44 arranged between the shell 42 and the rolling curtain 43; one end of the rolling curtain 43 connected to the rolling curtain driving member 44 is wound in the shell 42, and the other end of the rolling curtain 43 passes through the through hole 370 and is connected and fixed to the fixing frame 21, and the rolling curtain 43 is driven by the arc-shaped side panel 37. Guide to prevent the roller blind 43 from being damaged during the extension and retraction process. The roller blind 43 is mainly used to block the top of the building to prevent the interior of the building from being blown by the wind, exposed to the sun and rain. The moving part 60 is installed on the column 11 and the mounting frame 41. The moving part 60 is used to contact with the external ground to reduce the friction resistance and ensure the stability of the unfolding and folding operation of the building. The mobile drive device 80 is used to drive the relative movement between the columns 11. By controlling the working state of the mobile drive device 80, the building is controlled to unfold or fold accordingly to achieve one-button operation control. At the same time, by controlling the start and pause of the mobile drive device 80, the unfolded volume of the building can be adjusted and controlled.

[0057] The above-mentioned retractable building 100 realizes the unfolding and folding operation of the building in the horizontal direction by setting a fixed frame 21 and a beam body 31 that are sequentially connected, and a mounting frame 41 that is stacked in sequence; one end of the roller shutter 43 is wound in the shell 42, and the other end of the roller shutter 43 passes through the through hole 370 to be connected and fixed to the fixed frame 21, and by setting folding side walls 50 on both sides, the unfolding and folding operation of the building in the longitudinal direction is realized (the transverse direction is the relative movement direction of each column 11 in the same first support group 12, and the longitudinal direction is the relative movement direction of the first column support group 12 and the second column support group 13). The relative movement between the columns 11 and the columns 11 is driven by the mobile driving device 80, thereby realizing the one-button unfolding and folding operation of the building, which does not require additional personnel operation, saves manpower and time, is simple to operate, easy to use, and avoids the generation of waste during disassembly and assembly.

[0058] By setting the reel assembly 40 on the side of the first column support group 12 away from the second column support group 13, the roller blind 43 is guided through the side panel 37 and then connected and fixed to the fixing frame 21, so as to shield the top of the building. It does not need to be set on the top of the building, thereby reducing the thickness of the roof of the building. The roller blind itself is heavy, and setting it on one side can reduce the weight of the roof, reduce the load-bearing capacity of the columns, and lower the center of gravity of the entire building, thereby improving the overall stability of the building. Setting the reel assembly 40 on one side has more sufficient installation space to ensure the shrinkage and folding effect of the reel assembly 40, thereby achieving a larger shrinkage ratio of the entire building.

[0059] By controlling the working state of the mobile drive device 80, the building is controlled to be unfolded or folded accordingly, thereby realizing one-touch operation control. Meanwhile, by controlling the start and pause of the mobile drive device 80, the unfolded volume of the building can be adjusted and controlled to adapt to the external space restrictions and realize any area setting within the maximum extension area.

[0060] Furthermore, the column 11 is arranged in the vertical direction, and the column 11 is a liftable structure in the vertical direction to adjust the height of the building, thereby realizing a three-dimensional contraction structure of the building in the horizontal, longitudinal and height directions, greatly improving the contraction ratio of the building, and the contraction ratio of the floor area of ​​the building in the folded state and the unfolded state can reach 1:31. In this embodiment, the column 11 includes a base column 15, a lifting column 16 slidably arranged on the base column 15, and a lifting drive 17 connected to the lifting column 16. The base column 15 is in the shape of a straight rod and is arranged in the vertical direction. The lifting column 16 is in the shape of a straight rod. The lifting column 16 is arranged parallel to the base column 15. The lifting column 16 is arranged on one side of the base column 15. The lifting drive 17 is arranged in parallel with the base column 15. The bottom end of the lifting drive 17 is relatively fixed to the base column 15. The top end of the lifting drive 17 is connected to the lifting column 16. The lifting drive 17 is inserted into the lifting column 16. The lifting drive 17 is used to drive the lifting column 16 to move relative to the base column 15, thereby realizing the lifting operation of the column 11, so as to realize the adjustment and control of the building height. The folding and unfolding operation of the building in the three-dimensional space direction is realized by adjusting and controlling the building height. The volume contraction ratio of the building in the folded state and the unfolded state can reach one to fifty-four. Specifically, the floor area in the contracted state is 1.34m×1.2m=1.6m 2 The volume in the contracted state is 1.34m×1.2m×1.92m=3.08m 3 ; The floor space in the extended state is 6.07m×8.4m=51m 2 The volume in the extended state is 6.07m×8.4m×3.25m=165.7m 3 It can be understood that the lifting drive member 17 can be a hydraulic cylinder, a pneumatic cylinder or a screw mechanism, as long as it can drive the lifting column 16 to move relative to the base column 15, and the specific structure of the lifting drive member 17 is not specifically limited.

[0061] Furthermore, a slide groove 18 is provided on the base column 15, and a slider 19 is provided on one side of the lifting column 16; the slide groove 18 is in the shape of a long strip extending in the vertical direction, and the slider 19 is slidably arranged in the slide groove 18, and the cross section of the slider 19 is arranged in an H-shaped structure (the cross section refers to the plane along the direction perpendicular to the lifting column 16), and the slide groove 18 corresponds to the shape of the slider 19. By setting the H-shaped cross section, the connection reliability between the base column 15 and the lifting column 16 can be effectively improved, thereby ensuring the ability of the column 11 to withstand impact loads, making the lifting movement smoother. In this embodiment, the number of the columns 11 is eight, and the eight columns 11 are arranged in two rows in parallel, that is, the first column support group 12 and the second column support group 13 respectively include four columns 11, and the columns 11 of the first column support group 12 and the second column support group 13 are evenly spaced, and the setting positions of the columns 11 of the first column support group 12 and the second column support group 13 correspond.

[0062] Further, the telescopic beam 20 is arranged in the horizontal direction, and the telescopic beam 20 is sequentially connected to each column 11 of the second column support group 13. In this embodiment, the fixing frame 21 includes a fixing plate 25, a limit plate 26 arranged at one end of the fixing plate 25, a panel 27 connected to the fixing plate 25, and a top plate 28 connected to the panel 27. The fixing plate 25 is arranged in a rectangular straight plate-like structure, the fixing plate 25 is arranged in the horizontal direction, the fixing plate 25 is connected and fixed to the column 11, and the fixing plate 25 is arranged at the top of the second column support group 13; the limiting plate 26 is arranged in a rectangular straight plate-like structure, the limiting plate 26 is arranged at one end of the fixing plate 25, the limiting plate 26 is arranged in the vertical direction, the limiting plate 26 is perpendicular to the fixing plate 25, and the limiting plate 26 is used to limit the insertion depth position of the adjacent fixing frame 21; the panel 27 is arranged in a rectangular straight plate-like structure, the panel 27 is arranged on the side of the fixing plate 25 away from the first column support group 12, and the panel 27 is arranged perpendicular to the fixing plate 25 and the limiting plate 26; the top plate 28 is arranged in a rectangular straight plate-like structure, the top plate 28 and the fixing plate 25 are arranged in parallel, the fixing plate 25 is arranged on the top of the panel 27, the fixing plate 25 extends from the panel 27 toward the second column support group 13, and the fixing plate 25 is used to connect the roller blind 43. It can be understood that an opening is provided at one end of each fixing frame 21 away from the limiting plate 26 for the adjacent fixing frame 21 to be inserted, and then the length of the telescopic beam 20 is adjusted through the relative movement of each fixing frame 21 to adapt to the folding and unfolding operation of the second column support group 13. Furthermore, the length of the fixing plate 25 of each fixing frame 21 is different. Since the fixing plate 25 is connected to the column 11, the columns 11 are close to each other during the folding process. Therefore, the length of the fixing plate 25 is adjusted to avoid the position of the column 11 in the folded state, that is, the length of the fixing plate 25 of the fixing frame 21 set on the outermost side is the shortest, and the length of the fixing plate 25 of the fixing frame 21 set on the inner side increases in sequence.

[0063] Furthermore, the telescopic beam 30 is arranged in the horizontal direction, and the telescopic beam 30 is sequentially connected to each column 11 of the first column support group 12, and the telescopic beam 30 is arranged corresponding to the telescopic cross beam 20. In this embodiment, the beam body 31 also includes a support plate 35, an end plate 36 arranged at one end of the support plate 35, a guide block 38 connected to the support plate 35, and a baffle 39 connected to the guide block 38. The support plate 35 is arranged in a rectangular strip shape, and the support plate 35 extends in the horizontal direction; the end plate 36 is arranged in a straight plate shape, and the end plate 36 is perpendicular to the support plate 35. The end plate 36 is located at one end of the support plate 35, and the end plate 36 is used to limit the insertion depth position of the adjacent beam body 31; the cross-section of the side panel 37 is an arc shape (the direction of the cross-section is defined as the direction of the plane where the end plate 36 is located), and the side panel 37 is arranged on one side of the support plate 35. The arc structure allows the side panel 37 to extend from one side of the support plate 35 to the top of the support plate 35, and the side panel end plate 36 extends in the direction of the plane where the support plate 35 is located. An opening is provided at one end of the beam body 31 away from the end plate 36 for the adjacent beam body 31 to be inserted, and then the length of the telescopic beam 30 is adjusted by the relative movement of each beam body 31 to adapt to the folding and unfolding operation of the first column support group 12. Furthermore, the through hole 370 is in a rectangular strip shape and extends along the arc-shaped cross-section direction of the side panel 37. The through hole 370 is used for the rolling curtain 43 from the outside to pass through, and then the rolling curtain 43 is guided by the side panel 37, so that the rolling curtain 43 shields the rear side wall and the top surface of the building to achieve wind and rain protection, and the cross-section of the side panel 37 is set to be an arc shape to effectively avoid scratches on the rolling curtain 43 and ensure the service life. It can be understood that the side panel 37 and the support plate 35 are spaced apart to ensure that the bottom of the side panel 37 is exposed, so as to facilitate the rolling curtain 43 from the outside to pass through the through hole 370.

[0064] Further, the guide block 38 is arranged at the bottom of the casing, the guide block 38 is connected to the column 11, the guide block 38 is arranged in an L-shaped structure, one end of the guide block 38 is arranged in the vertical direction, and the other end of the guide block 38 is arranged in the horizontal direction. The end of the guide block 38 arranged in the vertical direction is connected and fixed to the support plate 35, and the end of the guide block 38 arranged in the horizontal direction is hooked toward the end plate 36, and the end of the guide block 38 arranged in the horizontal direction is connected and fixed to the top of the first column support group 12. It can be understood that the end of the guide block 38 close to the end plate 36 is provided with an opening to ensure that when two adjacent beams 31 move relative to each other, the guide block 38 is correspondingly inserted into the opening of the guide block 38 of the adjacent beam 31, thereby ensuring the stability of the relative movement of the beams 31 and improving the reliability of the connection position of the two adjacent beams 31. Furthermore, the baffle 39 is arranged in a rectangular strip structure, the baffle 39 is covered on one side of the guide block 38, and the top of the baffle 39 is connected to the support plate 35. The baffle 39, the support plate 35 and the guide block 38 form a channel steel structure, and then the setting of the baffle 39 effectively improves the bearing strength of the support plate 35 and the connection reliability between the guide block 38 and the support plate 35; the baffles 39 of each beam body 31 are stacked in sequence, and the limiting grooves 390 and the limiting blocks 395 are respectively arranged on both sides of the baffle 39, and the limiting blocks 395 of the two adjacent beam bodies 31 are correspondingly embedded in the limiting grooves 390 to prevent the two adjacent beam bodies 31 from detaching from each other during the movement, thereby realizing the limiting effect during the unfolding process. It can be understood that because one end of each guide block 38 arranged in the horizontal direction is connected to the column 11, the columns 11 are close to each other and fit together during the folding process, so the length dimension of the one end of the guide block 38 arranged in the horizontal direction is adaptively adjusted to ensure that the columns 11 that are close to each other in the folded state are avoided, that is, the length dimension of the one end of the guide block 38 arranged in the outermost direction is the shortest, and the length dimension of the one end of the guide block 38 arranged in the inner direction increases successively.

[0065] Furthermore, the reel assembly 40 is arranged on the side of the first column support group 12 away from the second column support group 13; the mounting frame 41 is used to fix the shell 42 on the column 11, and the mounting frame 41 includes a connecting portion 45, an extending portion 46 connected to the connecting portion 45, and a supporting portion 47 connected to the extending portion 46. The connecting portion 45 is arranged in a rectangular long strip structure, one end of the connecting portion 45 is connected and fixed to the column 11, and the other end of the connecting portion 45 is extended in the horizontal direction; the extending portion 46 is arranged in a rectangular long strip structure, the extending portion 46 is connected to the end of the connecting portion 45 away from the column 11, the extending portion 46 is extended from the connecting portion 45 in the direction away from the column 11, and the extending portion 46 is perpendicular to the connecting portion 45; the supporting portion 47 is arranged in a rectangular straight plate structure, the supporting portion 47 is arranged at the end of the extending portion 46 away from the connecting portion 45, the extending portion 46 is connected to the bottom of the supporting portion 47, and the supporting portion 47 is arranged parallel to the connecting portion 45, the shell 42 is correspondingly fixed on the supporting portion 47, and the shell 42 is arranged at the end of the supporting portion 47 away from the extending portion 46. Since the rolling curtain 43 itself has a heavy mass, by arranging the rolling curtain 43 at the top of the supporting portion 47, the reliability of the supporting strength of the rolling curtain 43 can be greatly improved. It can be understood that an opening is provided on one side of the mounting frame 41 away from the extension portion 46 to ensure that the adjacent mounting frames 41 are inserted from the opening when folded, thereby realizing the folding operation; because the connecting portion 45 is connected to the column 11, the length of the connecting portion 45 needs to be adaptively adjusted to avoid the setting position of the column 11 in the folded state because the columns 11 fit together when folded; at the same time, because the shell 42 is arranged at the top end of the support portion 47, the height of each support portion 47 is adaptively adjusted in turn to ensure that each shell 42 is staggered, and then each shell 42 is successively retracted into the outermost mounting frame 41 when folded.

[0066] Further, the housing 42 is arranged in a hollow rectangular structure, the housing 42 is arranged in the horizontal direction, and the housing 42 is arranged parallel to the beam body 31; the rolling curtain 43 is arranged in a rectangular strip structure, the rolling curtain 43 is a flexible member, and the rolling curtain 43 is used to block sunlight and rain, thereby ensuring the comfort of people in the building structure.

It can be understood that the output shaft of the rolling curtain driving member 44 is connected to the rolling curtain 43, and the rolling curtain 43 is wound on the output shaft. The rolling curtain driving member 44 controls the rotation of the output shaft to control the extension or retraction of the rolling curtain 43 to meet the deployment and folding operations of the entire building. In another embodiment, the rolling curtain driving member 44 is a torsion spring, which applies an elastic pulling force to the rolling curtain 43 in the direction of the housing 42 through its own elastic deformation, thereby ensuring that the rolling curtain 43 is always in a tensioned state during the relative movement of the pillars 11 and the pillars 11 along the longitudinal direction. It can be understood that the structure of the rolling curtain driving member 44 is similar to the torsion spring structure inside the tape measure, and the specific structure of the rolling curtain driving member 44 is not limited here, and it is ensured that the elastic pulling force can be applied to the rolling curtain 43 in the direction of the inside of the housing 42, so that the rolling curtain 43 is always in a tensioned state.

[0067] Furthermore, the fixing frame 21 , the beam body 31 , the mounting frame 41 , the housing 42 and the rolling curtain 43 are respectively arranged in a one-to-one correspondence.

[0068] Furthermore, folding side walls 50 are provided between adjacent columns 11, and the folding side walls 50 are used to shield the surroundings of the building, thereby preventing people in the building from being affected by the external environment in the surrounding directions. It can be understood that since the reel assembly 40 is provided outside the first column support group 12, the folding side walls 50 can be selectively provided between the columns of the first column support group 12; Figure 1The folding side wall 50 disposed between each column 11 of the second row support group 13 is hidden in the figure, so as to facilitate the display of the internal structure of the building. Specifically, the folding side wall 50 includes at least two plates 51. The plates 51 are arranged in a rectangular strip structure, and the plates 51 are arranged in the vertical direction. Each plate 51 is hinged in sequence, and the folding side wall 50 is arranged in a reciprocating winding shape. The side edges of two adjacent plates 51 are hinged to each other, and the unfolding and folding operations of the folding side wall 50 are realized by the relative rotation between each plate 51. In this embodiment, two folding side walls 50 are arranged between two adjacent columns 11, and the two folding side walls 50 are arranged in parallel and staggered. The two folding side walls 50 are respectively connected to the base column 15 and the lifting column 16 to ensure that when the column 11 is adjusted in height, the folding side wall 50 effectively protects the side of the building to meet the use requirements of the building height adjustment. Furthermore, the folding side wall 50 between the first column support group 12 and the second column support group 13 is provided with a reinforcing column 55, the structure of which is the same as that of the column 11, and the specific structure of the reinforcing column 55 is not described here, and the reinforcing column 55 is used to improve the bearing capacity of the folding side walls 50 on both sides of the building, thereby ensuring the reliability of the building. In this embodiment, a receiving groove 110 is provided at the connection position between the column 11 and the folding side wall 50, and the receiving groove 110 is provided in a rectangular groove-shaped structure, and the end of the folding side wall 50 is fixed in the receiving groove 110, and the receiving groove 110 is used to accommodate the folded folding side wall 50, so that the side of the building in the folded state is more flat and beautiful.

[0069] Furthermore, the moving member 60 is arranged at the end of the column 11 and the mounting frame 41 to abut against the external ground, and then the moving member 60 ensures the stability of the column moving relative to the ground; the moving member 60 includes a connecting plate 61 and a universal wheel 62 connected to the connecting plate 61. The connecting plate 61 is arranged in a straight plate-like structure, and the connecting plate 61 is used to fix the moving member 60 on the column 11 and the mounting frame 41; the universal wheel 62 can rotate in the direction of the plane where the connecting plate 61 is located, thereby realizing omnidirectional movement. In this embodiment, the connecting plate 61 is arranged in a rectangular straight plate-like structure, and the universal wheel 62 is arranged in a rectangular array at the four corners of the connecting plate 61.

[0070] Further, the mobile driving device 80 is arranged at the end of the column 11, and the mobile driving device 80 is hinged with the moving member 60. Specifically, the mobile driving device 80 includes a wheel frame 81, driving wheels 82 relatively arranged on both sides of the wheel frame 81, and a driving motor 83 connected to the driving wheels 82. The top of the wheel frame 81 is cylindrical and hinged on the connecting plate 61, so that the wheel frame 81 can rotate relative to the connecting plate 61, and the bottom of the wheel frame 81 is arranged in a hollow rectangular structure to accommodate the driving motor 83; the driving wheels 82 are relatively arranged on both sides of the wheel frame 81, and the number of the driving motors 83 is two, the two driving motors 83 are fixed on the wheel frame 81, and the two driving motors 83 are respectively connected to the driving wheels 82 on both sides, and the driving motor 83 is used to drive the driving wheels 82 to rotate, and the driving wheels 82 on both sides are relatively driven independently. It can be understood that the driving wheels 82 on both sides move in a straight line when they rotate at the same speed and in the same direction; when the driving wheels 82 on both sides rotate at the same speed and in opposite directions, the position of the moving member 60 does not move, but the wheel frame 81 rotates relative to the connecting plate 61, thereby adjusting the moving direction; when the driving wheels 82 on both sides rotate at different speeds, they can realize turning movement to meet the folding and unfolding operations in the horizontal and vertical directions of the building. In this embodiment, by controlling the speed and direction of the two driving motors 83, the driving column 11 is automatically moved and controlled, thereby realizing the automatic folding and unfolding operation of the building; the wheel frame 81 is set at the center of the connecting plate 61, and each universal wheel 62 is arranged around the outer side of the wheel frame 81. It can be understood that the retractable building 100 is provided with a control unit (not shown); each mobile driving device 80 is electrically connected to the control unit, and each mobile driving device 80 can be uniformly controlled by the control unit. The control unit is provided with a wireless communication module to receive wireless control signals, and then remotely control the one-button unfolding and folding operation of the building through the mobile terminal, and can control the movement of the building at the same time, without the need for manual handling to improve the user experience.

[0071] Furthermore, the retractable building 100 further includes a reinforcing rod 70; the reinforcing rod 70 is arranged between the telescopic cross beam 20 and the telescopic room beam 30, and the reinforcing rod 70 is used to improve the ability of the first column support group 12 and the second column support group 13 to bear the lateral load. Specifically, the reinforcing rod 70 includes at least two rod bodies 71, and each rod body 71 is hingedly arranged in sequence to meet the requirements of folding and unfolding of the overall building structure; in this embodiment, the number of the rod bodies 71 is four, and the reinforcing rod 70 is folded into a W-shaped structure.

[0072] The working process of the present invention is as follows: first, the retractable building 100 is moved to the designated deployment position by the mobile driving device 80. After receiving the deployment command, each mobile driving device 80 first moves along the direction in which the first row of support groups 12 are set, that is, in the lateral direction, so that each column 11 is relatively far away from each other, and at the same time, the columns 11 are also relatively far away from each other. At this time, the fixing frame 21 and the beam body 31 are And the mounting frame 41 extends out in sequence to adapt to the unfolding operation along the setting direction of the first column support group 12; after the unfolding operation along the setting direction of the first column support group 12 is completed, each mobile drive device 80 moves in a direction perpendicular to the setting direction of the first column support group 12, that is, in the longitudinal direction, and the first column support group 12 moves away from the second column support group 13. At this time, the folding side walls 50 on both sides are unfolded by the relative rotation between the plate bodies 51, and the reinforcing rods 70 are synchronously unfolded by the relative rotation between the rod bodies 71. During the movement, a pulling force is applied to the roller shutter 43 to pull the roller shutter 43 out of the shell 42, thereby realizing the unfolding operation along the setting direction perpendicular to the first column support group 12; and then the lifting drive member 17 drives the lifting column 16 to move relative to the base column 15 to realize the adjustment and control of the building height, complete the unfolding instruction, and the building unfolds in a three-dimensional direction.

[0073] When the folding instruction is received, the operation process is opposite to the unfolding operation, that is, the lifting column 16 is first controlled to fall back through the lifting drive member 17, and then the first column support group 12 and the second column support group 13 are driven to approach each other through the mobile drive device 80. At this time, the folding side wall 50 is folded into the accommodating groove 110, and the rod body 71 of the reinforcing rod 70 is also rotated and folded with each other. The roller shutter 43 is driven by the roller shutter drive member 44 to roll back into the shell 42. Finally, the mobile drive device 80 drives the columns 11 to approach and fit together. At the same time, the fixed frame 21, the beam body 31 and the mounting frame 41 are inserted and folded in sequence to form a folding structure that is arranged in sequence. The folding instruction is completed, and the building is folded along the three-dimensional direction.

[0074] See also Fig.10, which is a retractable building 200 of the second embodiment of the present invention, and is different from the retractable building 100 of the first embodiment in that a mobile driving device 80a of the retractable building 200 in this embodiment is arranged between two adjacent columns, and the mobile driving device 80a is arranged on the outside of the folding side wall 50, and the mobile driving device 80a includes a first cross rod 91, a second cross rod 95 and a folding driving member (not shown). The first cross rod 91 is arranged in a long strip structure, and the second cross rod 95 is arranged in a long strip structure. The first cross rod 91 and the second cross rod 95 are hinged at the middle position, and the first cross rod 91 and the second cross rod 95 are arranged in an X-shaped structure. One end of the first cross rod 91 and the second cross rod 95 are hinged to the column 11, and the other end of the first cross rod 91 and the second cross rod 95 are slidably arranged on another adjacent column 11. The folding drive member is connected to one end of the sliding structure to adjust the angle between the first cross rod 91 and the second cross rod 95, so as to adjust the relative distance between the columns 11 by adjusting the angle between the first cross rod 91 and the second cross rod 95. It can be understood that the folding drive member can be one of a cylinder, a hydraulic cylinder or a screw mechanism. The specific structure of the folding drive member is not specifically limited here. It is ensured that the folding drive member can drive and control the first cross rod 91 and the second cross rod 95 to slide on the column 11 or the column 11, and then adjust the angle between the first cross rod 91 and the second cross rod 95.

[0075] Furthermore, multiple groups of first cross bars 91 and second cross bars 95 arranged in an X-shaped structure can be arranged between two adjacent columns 11, and folding driving members corresponding to driving the first cross bars 91 to rotate relative to the second cross bars 95 can be arranged respectively. The principle is the same as that of setting one group, and it will not be repeated here. By arranging the first cross bars 91 and the second cross bars 95 crossing in an X-shaped structure on the outside of the folding side wall 50, the driving control of the relative movement between the first column support group 12 and the second column support group 13 is ensured, while the performance of the folding side wall 50 in resisting lateral impact is improved, and the bearing capacity of the folding side wall 50 is further improved. It can be understood that the mobile driving device 80a in this embodiment can be used in combination with the mobile driving device 80 in the first embodiment, and the folding driving member is not arranged, that is, it is driven by the mobile driving device 80, and the connection reliability between adjacent columns is improved by the first cross bars 91 and the second cross bars 95 in an X shape.
