Description

Technical Field

[0001] The invention belongs to the field of shelter equipment, and in particular relates to an intelligent high-expansion-retraction ratio expansion shelter. Background Art

[0002] Shelters are transportable box-type workrooms that are organically combined with various solid materials. Shelters are divided into fixed and extended, and can be used for various purposes such as command, medical treatment, and cooking.

[0003] The expansion cabin can provide a good spatial environment for working in the field. Various design studies on expansion cabin structures have been widely carried out at home and abroad. However, the existing expansion cabin structure is generally a double expansion structure of 1 expansion to 3, with a relatively low expansion and retraction ratio, and the internal space after expansion is limited. The only cabins with a relatively high expansion and retraction ratio are all expanded manually, and fully automatic expansion and retraction have not yet been achieved. The cabin is affected by the unevenness of the road surface during the expansion and retraction process, and the bottom plate of the expansion part cannot automatically adjust the height, which must be done manually. It can be seen that the existing expansion cabins have a low expansion and retraction ratio, poor automation, and long deployment time, which seriously restricts the speed of field deployment of the cabins and cannot meet the needs of rapid deployment in field conditions.

Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0094] For example, the intelligent high expansion and contraction ratio expansion cabin designed by the present invention can be automatically expanded and contracted, and can also be manually expanded and contracted.

The structures of the left expansion cabin and the right expansion cabin are completely symmetrical, and the expansion and retraction methods are the same. This article uses the left expansion cabin as an example. Those skilled in the art can derive the structure and expansion and retraction method of the right expansion cabin from the structure and expansion and retraction method of the left expansion cabin.

[0095] Specifically, the connecting rods include a left first-level front connecting rod, a left first-level rear connecting rod, a left second-level front connecting rod, a left second-level rear connecting rod, a left third-level front connecting rod, a left third-level rear connecting rod, a right first-level front connecting rod, a right first-level rear connecting rod, a right second-level front connecting rod, a right second-level rear connecting rod, a right third-level front connecting rod and a right third-level rear connecting rod.

[0096] For example, the connecting rods in the present invention are used in multiple places in the entire cabin. The left first-level front connecting rod, the left first-level rear connecting rod, the left second-level front connecting rod, the left second-level rear connecting rod, the left third-level front connecting rod, the left third-level rear connecting rod, the right first-level front connecting rod, the right first-level rear connecting rod, the right second-level front connecting rod, the right second-level rear connecting rod, the right third-level front connecting rod and the right third-level rear connecting rod have the same functional structure, but are used in different places in different cabins and have different names.

[0097] Specifically, the left-level expansion cabin 2, the left-level expansion cabin 3, the left-level expansion cabin 4, the right-level expansion cabin 5, the right-level expansion cabin 6 and the right-level expansion cabin 7 can be folded into the main cabin 1; the main cabin 1 is a rectangular structure, including a main front panel, a main rear panel, a main top panel and a main bottom panel; the left-level expansion cabin 2 includes a left-level expansion frame, a left-level expansion top panel, a left-level expansion front end panel, a left-level expansion rear end panel and a left-level expansion bottom panel; the left-level expansion cabin 3 includes a left-level expansion frame, a left-level expansion top panel, a left-level expansion front end panel, a left-level expansion rear end panel and a left-level expansion bottom panel; the left-level expansion cabin 4 includes a left-level expansion frame, a left-level expansion top panel, a left-level expansion front end panel, a left-level expansion rear end panel, a left-level expansion bottom panel and a left-level expansion side panel.

[0098] For example, the intelligent high-expansion-retraction ratio expansion cabin designed by the present invention, the left first-level expansion cabin 2, the left second-level expansion cabin 3, the left third-level expansion cabin 4, the right first-level expansion cabin 5, the right second-level expansion cabin 6 and the right third-level expansion cabin 7 can be folded into the main cabin 1, Figure 2 This is a cross-sectional rendering of the main cabin after folding. After folding, the cabin is a rectangular parallelepiped structure, and its surface is composed of the main front plate, the main rear plate, the main top plate, the main bottom plate, the left first-level extended top plate and the right first-level extended top plate. Another design, after folding, the cabin is a rectangular parallelepiped structure, and its outer surface is composed of the main front plate, the main rear plate, the main top plate, the main bottom plate, the left first-level extended bottom plate and the right first-level extended bottom plate. After unfolding, the cabin is composed of seven rectangular parallelepiped structures, among which the main cabin 1 is larger, and the left first-level extended cabin 2, the left second-level extended cabin 3, the left third-level extended cabin 4, the right first-level extended cabin 5, the right second-level extended cabin 6 and the right third-level extended cabin 7 are slightly smaller. The main cabin 1 is a rectangular parallelepiped structure, including the main front plate, the main rear plate, the main top plate and the main bottom plate. The left first-stage expansion cabin 2 is a rectangular parallelepiped structure, including a left first-stage expansion frame, a left first-stage expansion top plate, a left first-stage expansion front end plate, a left first-stage expansion rear end plate and a left first-stage expansion bottom plate; the left second-stage expansion cabin 3 is a rectangular parallelepiped structure, including a left second-stage expansion frame, a left second-stage expansion top plate, a left second-stage expansion front end plate, a left second-stage expansion rear end plate and a left second-stage expansion bottom plate; the left third-stage expansion cabin 4 is a rectangular parallelepiped structure, including a left third-stage expansion frame, a left third-stage expansion top plate, a left third-stage expansion front end plate, a left third-stage expansion rear end plate, a left third-stage expansion bottom plate and a left third-stage expansion side plate. There is no partition between the main cabin 1 and the left first-stage expansion cabin 2, the left first-stage expansion cabin 2 and the left second-stage expansion cabin 3, and the left second-stage expansion cabin 3 and the left third-stage expansion cabin 4.

[0099] Specifically, the left side of the main top plate is connected to the left first-level extension top plate axis, and the front and rear ends of the left side of the main cabin body 1 are respectively provided with electric struts, and the other ends of the two electric struts are fixedly connected to the front and rear ends of the left first-level extension top plate, and the two electric struts can drive the left first-level extension top plate to rotate along the axis; the left first-level extension frame is a hollow rectangular structure, and the lower side axis of the left first-level extension frame is connected to the left first-level extension bottom plate, and the left first-level extension bottom plate is arranged on the side of the left first-level extension frame close to the main cabin body 1, and an electric strut is further arranged between the left first-level extension frame and the left first-level extension bottom plate, and the electric strut can drive the left first-level extension bottom plate to rotate along the axis; The front axis of the left-level expansion frame is connected to the left-level expansion front end plate, and the left-level expansion front end plate is arranged on the side of the left-level expansion frame close to the main cabin body 1, and an electric support rod is also arranged between the left-level expansion frame and the left-level expansion front end plate, and the electric support rod can drive the left-level expansion front end plate to rotate along the axis; the rear axis of the left-level expansion frame is connected to the left-level expansion rear end plate, and the left-level expansion rear end plate is arranged on the side of the left-level expansion frame close to the main cabin body 1, and an electric support rod is also arranged between the left-level expansion frame and the left-level expansion rear end plate, and the electric support rod can drive the left-level expansion rear end plate to rotate along the axis.

[0100] For example, the intelligent high expansion and contraction ratio expansion cabin designed by the present invention has its bottom plate, front plate, and rear plate all arranged on corresponding frames, and the top plate arranged on the upper-level cabin (the upper level of the third-level cabin is the second-level cabin, the upper level of the second-level cabin is the first-level cabin, and the upper level of the first-level cabin is the main cabin). When expanding, first unfold its top plate, then unfold its front and rear plate at the same time, and finally unfold its bottom plate; when folding, first fold its bottom plate, then fold its front and rear plate at the same time, and finally fold its top plate. Figure 3 As shown, Figure 3The figure shows the rear view of the intelligent high-expansion-retraction ratio expansion cabin, and its left expansion cabin is on the right side of the main cabin when viewed from the rear. The left side of the main top plate is connected to the axis of the left first-level expansion top plate, and the front and rear ends of the left side of the main cabin 1 are each provided with an electric strut, one end of the two electric struts is connected to the front and rear ends of the left side of the main cabin 1, and the other end of the two electric struts is connected to the front and rear ends of the left first-level expansion top plate, and the two electric struts can drive the left first-level expansion top plate to rotate along the axis. When the two electric struts are spread out, the left first-level expansion top plate can be rotated along the axis to be parallel to the plane where the main bottom plate is located. When the two electric struts are retracted, the left first-level expansion top plate can be driven to rotate along the axis to be perpendicular to the plane where the main bottom plate is located. The left first-level expansion frame is a hollow rectangular structure. The left first-level expansion bottom plate, the left first-level expansion front end plate, and the left first-level expansion rear end plate are all arranged on the side of the left first-level expansion frame close to the main cabin 1, that is, the right side. The front side of the left-level expansion frame is connected to the left-level expansion front end plate axis, the rear side of the left-level expansion frame is connected to the left-level expansion rear end plate axis, and the lower side of the left-level expansion frame is connected to the left-level expansion bottom plate axis. Electric struts are arranged between the left-level expansion frame and the left-level expansion front end plate, the left-level expansion frame and the left-level expansion rear end plate, and the left-level expansion frame and the left-level expansion bottom plate. These electric struts can respectively drive the left-level expansion front end plate, the left-level expansion rear end plate and the left-level expansion bottom plate to rotate along the axis. These electric struts can be arranged at any position of the left-level expansion frame, as long as they can meet the requirements that after being stretched, the left-level expansion front end plate, the left-level expansion rear end plate and the left-level expansion bottom plate can be expanded into place and are relatively perpendicular to the left-level expansion frame. After being retracted, the left-level expansion front end plate, the left-level expansion rear end plate and the left-level expansion bottom plate rotate along the axis and are relatively parallel to the plane where the left-level expansion frame is located. Preferably, two electric struts are arranged between the left-level expansion frame and the left-level expansion bottom plate, and one end of the two electric struts is respectively connected to the front and rear sides of the left-level expansion frame, and the other end is connected to the front and rear ends of the left-level expansion bottom plate. This connection method allows the extended top plate and the extended bottom plate to be powered by electric struts installed on both sides (ie, each can rotate around the connection axis separately). Both ends are supported and can be stressed at the same time, making the extension and retraction smoother.

[0101] Specifically, the left side of the front end of the main base plate is fixedly connected to the first end of the left-level front connecting rod, the second end of the left-level front connecting rod is connected to the lower end of the left-level extended front end plate, and the first end and the second end of the left-level front connecting rod can rotate horizontally; the left side of the rear end of the main base plate is connected to the first end of the left-level rear connecting rod, the second end of the left-level rear connecting rod is connected to the lower end of the left-level extended rear end plate, and the first end and the second end of the left-level rear connecting rod can rotate horizontally.

[0102] Exemplarily, in the present invention, the extended front and rear end plates and the frame are unfolded / folded together. The left side of the front end of the main base plate is connected to the first end of the left-level front connecting rod, the second end of the left-level front connecting rod is connected to the lower end of the left-level extended front end plate, and the first and second ends of the left-level front connecting rod can rotate horizontally; the left side of the rear end of the main base plate is connected to the first end of the left-level rear connecting rod, the second end of the left-level rear connecting rod is connected to the lower end of the left-level extended rear end plate, and the first and second ends of the left-level rear connecting rod can rotate horizontally. Preferably, the connection is an axial connection. The connecting rod can have a variety of designs, as long as the connecting rod can be divided into two sections, the middle can rotate, and the connecting rod can be telescopic.

[0103] Since the left first-stage expansion front end plate and the left first-stage expansion rear end plate are respectively connected to the left first-stage expansion frame shaft, and electric struts are arranged between the left first-stage expansion front end plate and the left first-stage expansion frame, and between the left first-stage expansion rear end plate and the left first-stage expansion frame. When folded, the left first-stage expansion frame is subjected to an inward thrust (the thrust is transmitted from the left third-stage expansion cabin 4 to the left second-stage expansion cabin 3, and the left second-stage expansion cabin 3 is transmitted to the left first-stage expansion frame). The folded left second-stage expansion cabin 3 and the left third-stage expansion cabin 4 also move outward together. Under the action of the electric struts, the left first-stage expansion base plate closes to the left first-stage expansion frame. After the left first-stage expansion base plate is folded, the electric struts between the left first-stage expansion frame and the left first-stage expansion front end plate and the left first-stage expansion rear end plate drive the left first-stage expansion front end plate and the left first-stage expansion rear end plate to close to the left first-stage expansion frame. The left first-stage expansion front end plate drives the left first-stage front connecting rod to rotate toward the center direction of the main base plate, and the left first-stage expansion rear end plate drives the left first-stage rear connecting rod to rotate toward the center direction of the main base plate. Under the coordinated action of multiple forces, the left first-stage expansion front plate and the left first-stage expansion rear plate are finally closed together with the left first-stage expansion frame; and under the limiting action of the left first-stage front connecting rod and the left first-stage rear connecting rod, the left first-stage expansion frame and the folded left second-stage expansion cabin 3 and the left third-stage expansion cabin 4 are received into the main cabin 1. Finally, the left first-stage expansion top plate is closed to the main cabin 1. In this way, the left first-stage expansion cabin 2 is folded.

[0104] When unfolding, the left first-stage expansion top plate first unfolds upward until it is parallel to the plane where the main bottom plate is located. The left first-stage expansion frame is subjected to an outward pulling force (the pulling force is transmitted from the left third-stage expansion cabin 4 to the left second-stage expansion cabin 3, and the left second-stage expansion cabin 3 to the left first-stage expansion frame), and the folded left second-stage expansion cabin 3 and the left third-stage expansion cabin 4 are close to the left first-stage expansion frame and move outward together. The electric support rod between the left first-stage expansion frame and the left first-stage expansion front end plate and the left first-stage expansion rear end plate drives the left first-stage expansion front end plate and the left first-stage expansion rear end plate to unfold outward; the left first-stage expansion front end plate drives the left first-stage front connecting rod to rotate in the opposite direction to the center of the main bottom plate, and the left first-stage expansion rear end plate drives the left first-stage rear connecting rod to rotate in the opposite direction to the center of the main bottom plate. Under the joint action of multiple forces, the left first-stage expansion front end plate and the left first-stage expansion rear end plate are finally unfolded, perpendicular to the left first-stage expansion frame, at which time the left second-stage expansion cabin 3 and the left third-stage expansion cabin 4 are still close to the left first-stage expansion frame. Finally, the left first-stage expansion bottom plate is unfolded. In this way, the left first-stage expansion cabin 2 is unfolded.

[0105] Specifically, the left-first-stage expansion frame is connected to the left-secondary expansion top plate axis, and the left-secondary expansion top plate is arranged on the side of the left-first-stage expansion frame away from the main cabin body 1, and an electric strut is respectively arranged at the front and rear ends of the left-first-stage expansion frame, and the other ends of the two electric struts are fixedly connected to the front and rear ends of the left secondary expansion top plate, and the two electric struts can drive the left secondary expansion top plate to rotate along the axis; the left secondary expansion frame is a hollow rectangular structure, and the lower side axis of the left secondary expansion frame is connected to the left secondary expansion bottom plate, and the left secondary expansion bottom plate is arranged on the side of the left secondary expansion frame close to the main cabin body 1, and an electric strut is also arranged between the left secondary expansion frame and the left secondary expansion front plate, and the electric strut can drive the left secondary expansion bottom plate to rotate along the axis; the front side axis of the left secondary expansion frame is connected to the left secondary expansion front end plate, and the left secondary expansion front end plate is arranged on the side of the left secondary expansion frame close to the main cabin body 1, and an electric strut is also arranged between the left secondary expansion frame and the left secondary expansion front end plate, and the electric strut can drive The left secondary extension front end plate is moved to rotate along the axis; the rear side axis of the left secondary extension frame is connected to the left secondary extension rear end plate, and the left secondary extension rear end plate is arranged on the side of the left secondary extension frame close to the main cabin body 1, and an electric strut is also arranged between the left secondary extension frame and the left secondary extension rear end plate, and the electric strut can drive the left secondary extension rear end plate to rotate along the axis; the bottom front end of the left primary extension frame is connected to the first end of the left secondary front connecting rod, the second end of the left secondary front connecting rod is connected to the lower end of the left secondary extension front end plate, and the first end and the second end of the left secondary front connecting rod can rotate horizontally; the bottom rear end of the left primary extension frame is connected to the first end of the left secondary rear connecting rod, the second end of the left secondary rear connecting rod is connected to the lower end of the left secondary extension rear end plate, and the first end and the second end of the left secondary rear connecting rod can rotate horizontally.

[0106] Exemplarily, the left side of the left primary expansion frame is connected to the left secondary expansion top plate axis. Preferably, the left side of the left primary expansion frame is connected to the left secondary expansion top plate via a hinge axis. The front and rear ends of the left primary expansion frame are each provided with an electric strut, one end of the two electric struts is connected to the front and rear ends of the left primary expansion frame, and the other ends of the two electric struts are connected to the front and rear ends of the left secondary expansion top plate. The two electric struts can drive the left secondary expansion top plate to rotate along the axis. When the two electric struts are spread out, the left secondary expansion top plate can be rotated along the axis to be parallel to the plane where the main bottom plate is located. When the two electric struts are retracted, the left secondary expansion top plate can be driven to rotate along the axis to be parallel to the plane where the left primary expansion frame is located. The left secondary expansion frame is a hollow rectangular structure. The left secondary expansion bottom plate, the left secondary expansion front end plate, and the left secondary expansion rear end plate are all arranged on the side of the left secondary expansion frame close to the main cabin body 1, that is, the right side. The front side of the left secondary expansion frame is connected to the left secondary expansion front end plate axis, the rear side of the left secondary expansion frame is connected to the left secondary expansion rear end plate axis, and the lower side of the left secondary expansion frame is connected to the left secondary expansion base plate axis.

[0108] The expansion and folding of the left secondary expansion cabin 3 is similar to that of the left primary expansion cabin 2. Those skilled in the art can deduce the expansion and folding method of the left secondary expansion cabin 3 from the left primary expansion cabin 2.

Electric struts are arranged between the left three-level extension frame and the left three-level extension front end plate, the left three-level extension frame and the left three-level extension rear end plate, and the left three-level extension frame and the left three-level extension bottom plate. These electric struts can respectively drive the left three-level extension front end plate, the left three-level extension rear end plate, and the left three-level extension bottom plate to rotate along the axis. These electric struts can be set at any position of the left three-level expansion frame, as long as they can meet the requirements that after being expanded, the left three-level expansion front end plate, the left three-level expansion rear end plate and the left three-level expansion bottom plate are expanded into place and can be relatively perpendicular to the left three-level expansion frame, and after being retracted, the left three-level expansion front end plate, the left three-level expansion rear end plate and the left three-level expansion bottom plate rotate along the axis and are relatively parallel to the plane where the left three-level expansion frame is located.

[0112] The unfolding and folding of the left third-level expansion cabin 4 is similar to that of the left first-level expansion cabin 2. After folding, from outside to inside, they are respectively the left first-level expansion top plate, the left second-level expansion top plate, the left third-level expansion top plate, the left third-level expansion frame (the left third-level expansion front plate, the left third-level expansion rear plate, the left third-level expansion bottom plate and the left third-level expansion side plate are folded on the left third-level expansion frame), the left second expansion frame (the left second-level expansion front plate, the left second-level expansion rear plate and the left second-level expansion bottom plate are folded on the left second-level expansion frame) and the left first-level expansion frame (the left first-level expansion front plate, the left first-level expansion rear plate and the left first-level expansion bottom plate are folded on the left first-level expansion frame). Those skilled in the art can deduce the unfolding and folding method of the left third-level expansion cabin 4 from the left first-level expansion cabin 2.

[0113] Specifically, the front and rear sides of the left-first-stage expansion frame, the left-second-stage expansion frame and the left-third-stage expansion frame are all provided with road surface adaptive devices, and the road surface adaptive devices are perpendicular to the plane where the main base plate is located; the front and rear sides of the bottom of the main base plate close to one end of the left-first-stage expansion cabin 2 are installed with linkage transition plates, and when the left-first-stage expansion cabin 2, the left-second-stage expansion cabin 3 and the left-third-stage expansion cabin 4 are folded, the road surface adaptive devices can be connected to the linkage transition plates. The road adaptive device includes a spring 91, an electric road support rod 92, a locking mechanism 93, a guide wheel 94 and an angle sensor; the first end of the electric road support rod 92 is provided with a telescopic part, and the second end of the electric road support rod 92 is fixedly connected to the guide wheel 94; the first end of the telescopic part of the electric road support rod 92 penetrates the spring 91, and the second end of the telescopic part of the electric road support rod 92 is provided with a locking mechanism 93, and the locking mechanism 93 can lock the electric road support rod 92 so that the electric road support rod 92 cannot be telescoped; a motor is provided inside the electric road support rod 92, and the motor can drive the electric road support rod 92 to telescope, and a Hall sensor is provided inside the motor, and the Hall sensor is used to collect motor working information. A planetary reduction gear set and a worm gear are also provided inside the electric road support rod 92; the motor power output shaft is meshed with the sun gear in the planetary reduction gear set, and the planetary gear in the star reduction gear set is meshed with the worm gear, and the worm gear is used to drive the electric road support rod 92 to telescope. The rotation angle sensor is arranged outside the electric road support rod 92, and the rotation angle sensor can measure the difference between the ground level in the distance and the current ground level to generate ground information; the Hall sensor and the rotation angle sensor are connected to the central controller circuit; the central controller can adjust the magnitude and direction of the current supplied to the motor; the central controller can adjust the magnitude and direction of the current supplied to the motor in real time according to the received ground information and motor working information. The linkage transition plate is provided with a groove, and the guide wheel 94 can slide in the groove; the first end of the linkage transition plate is provided with a connector, and the linkage transition plate can be connected to the main bottom plate through the connector.

[0114] For example, the road surface adaptive device used in the present invention can automatically adjust according to the actual road surface conditions to adapt to different terrain environments. This solves the problem that the expansion cabin cannot be normally deployed and retracted during deployment and retraction due to uneven road surfaces. Figure 1 As shown, the left first-stage expansion frame, the left second-stage expansion frame, and the left third-stage expansion frame are all provided with road surface adaptive devices on the front and rear sides, and the road surface adaptive devices are perpendicular to the plane where the main bottom plate is located. The road surface adaptive devices are used in conjunction with the linkage transition plate. The linkage transition plate is installed on the front and rear sides of the left end of the bottom of the main bottom plate. When the left first-stage expansion cabin 2, the left second-stage expansion cabin 3, and the left third-stage expansion cabin 4 are folded, the road surface adaptive devices can be connected to the linkage transition plate.

[0115] like Figure 4As shown, the road surface adaptive device includes a spring 91, an electric road surface support rod 92, a locking mechanism 93, a guide wheel 94 and a rotation angle sensor. The electric road surface support rod 92 can be extended or shortened. The electric road surface support rod 92 is connected to each expansion cabin frame, such as the left first-level expansion frame of the left first-level expansion cabin 2. Preferably, the uppermost end of the electric road surface support rod 92 is connected to each expansion cabin frame. By supporting the frame, the electric road surface support rod 92 can finally support the expansion cabin. Since the electric road surface support rod 92 can be extended or shortened, when the ground is uneven, the expansion cabin can be kept relatively horizontal by utilizing the function of the electric road surface support rod 92. The first end of the electric road surface support rod 92 is provided with a telescopic portion, which can be extended or shortened. The second end of the electric road surface support rod 92 is fixedly connected to the guide wheel 94. Preferably, the second end of the electric road surface support rod 92 is fixedly connected to the guide wheel 94 by bolts. This connection method is more convenient for later maintenance. The first end of the telescopic part of the electric road support rod 92 is penetrated by the spring 91, and the spring 91 plays a role of stable support. When the electric road support rod 92 is extended or shortened, due to the reaction force brought by the spring 91, the expansion cabin connected to the electric road support rod 92 is more stable. The second end of the telescopic part of the electric road support rod 92 is provided with a locking mechanism 93, and the locking mechanism 93 is used to lock the electric road support rod 92. When the electric road support rod 92 is already in a suitable position and has been adjusted to an appropriate length, the locking mechanism 93 prevents the electric road support rod 92 from being extended or extended. A motor is provided inside the electric road support rod 92, and the motor output is a rotational motion. A planetary reduction gear set and a worm gear are also provided inside the electric road support rod 92; the power output shaft of the motor is meshed with the sun gear in the planetary reduction gear set, and the planetary gear in the planetary reduction gear set is meshed with the worm gear to convert the rotational motion into a linear motion (up and down motion). The worm gear drives the electric road support rod 92 to extend and retract by moving up and down. The Hall sensor is arranged inside the motor, and the Hall sensor is used to collect motor working information, such as rotation speed, rotation direction, etc. Preferably, the guide wheel 94 has a locking function, when the guide wheel 94 is not locked, the guide wheel 94 can roll, when locked, the guide wheel 94 cannot roll.

[0116] Cabins are often used in the wild, and the ground is not flat. In order to ensure smooth expansion, the electric road support rod 92 needs to be adjusted in real time according to the road surface. The angle sensor is arranged on the outside of the electric road support rod 92, and the angle sensor is used to measure the difference between the horizontal height of the distant ground and the current ground level in real time to generate ground information. The Hall sensor and the angle sensor are connected to the central controller circuit. The motor working information collected by the Hall sensor, such as the speed, the direction of rotation, etc., is transmitted to the central controller, and the angle sensor transmits the ground information to the central controller. The electric road support rod 92 is driven by the guide wheel 94 to move vertically outward, and the central controller receives the ground information in real time. If the current ground has a bulge, the current size and direction of the motor are adjusted to make the electric road support rod 92 contract; if the current ground has a depression, the current size and direction of the motor are adjusted to make the electric road support rod 92 extend; when the electric road support rod 92 is finally kept in translation, the uppermost end of the electric road support rod 92 is relatively horizontal. Preferably, the central controller can also control the locking mechanism 93 to lock / unlock the electric road support rod 92.

[0117] like Figure 5 As shown, the linkage transition plate is provided with a groove, and the guide wheel 94 can slide in the groove. Preferably, the linkage transition plate is made of metal. A connecting piece is provided at the first end of the linkage transition plate, and the linkage transition plate can be connected to the main base plate through the connecting piece. The main base plate uses but is not limited to the following design, a slide groove is provided in the main base plate, the first end of the slide groove is close to the middle of the main base plate, and the second end of the slide groove is away from the middle of the main base plate, and the linkage transition plate can slide in the slide groove. When the linkage transition plate slides to the second end, the first end of the linkage transition plate is connected to the second end of the slide groove of the connecting piece, and the second end of the linkage transition plate can be lowered / lifted.

[0118] When the expansion cabin on the left is expanded, the first ends of the two linkage transition plates on the left are fixedly connected to the front and rear ends of the left side of the main bottom plate, and the guide wheels 94 of the six road surface adaptive devices are respectively arranged in the grooves in front and back. Under the outward pulling force, the left first-level expansion frame, the left second-level expansion frame, and the left third-level expansion frame move outward. The second ends of the two linkage transition plates are tilted downward, and the six guide wheels 94 on the three frames drive the six electric road surface support rods 92 to slide downward respectively. The six guide wheels 94 slide downward and separate from the linkage transition plate to reach the ground. This design allows the road surface adaptive system to have an upward support force from the bottom when it touches the ground from the main cabin, and this design makes the expansion of the square cabin more stable. When folded, the linkage transition plate also has a positioning function. The road surface adaptive device slides into the groove of the linkage transition plate, connects with the linkage transition plate, and the second end of the linkage transition plate moves upward, and finally the road surface adaptive device drives the frame to be loaded into the cabin. The linkage transition plate also plays a certain fixing role. When the expansion cabin is folded in the main cabin, the groove restricts the road surface adaptive device from longitudinal movement and can only slide along the groove direction. Preferably, a fixing device is also provided in the main cabin, and when the expansion cabin is folded into the main cabin, the fixing device can fix the folded expansion cabin so that it cannot be moved. Such a design makes the intelligent high-expansion cabin more convenient for transportation.

[0120] For example, the structure of the right expansion cabin is completely symmetrical with that of the left expansion cabin, and the deployment and retraction method is the same. Those skilled in the art can derive the structure and deployment and retraction method of the right expansion cabin from the structure and deployment and retraction method of the left expansion cabin.

[0121] Specifically, the connecting rod includes a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod are symmetrically arranged, and the second end of the first connecting rod and the second end of the second connecting rod are connected by a hinge mechanism 84; the first end of the first connecting rod is provided with a first pin hole 81, and the first end of the second connecting rod is provided with a second pin hole; the hinge mechanism 84 is fixedly provided with a first pin shaft 83 and a second pin shaft on both sides; the first connecting rod is fixedly provided with a first retaining spring 82, and the first retaining spring 82 is connected with the first pin shaft 83 in cooperation. The second end of the second connecting rod is fixedly provided with a second retaining spring, and the second retaining spring is connected with the second pin shaft in cooperation.

[0122] For example, the connecting rod used in the present invention is used to connect the expansion cabin and the main cabin into a whole, and is the main component to maintain the stability and directionality of the expansion cabin when it is deployed and retracted. The connecting rod is divided into two sections, such as Figure 6 As shown, it includes a first connecting rod and a second connecting rod, which are symmetrically arranged and connected in the middle by a hinge mechanism 84. A first pin hole 81 is arranged at the first end of the first connecting rod, and a second pin hole is arranged at the first end of the second connecting rod. The connecting rod is connected to the pins on the expansion cabin end plate and the main bottom plate through the pin holes at both ends. A first pin 83 and a second pin are fixedly arranged on both sides of the hinge mechanism; a first retaining spring 82 is fixedly arranged at the second end of the first connecting rod, and the first retaining spring 82 is matched and connected with the first pin 83; a second retaining spring is fixedly arranged at the second end of the second connecting rod, and the second retaining spring is matched and connected with the second pin. The matching of the pin and the retaining spring, plus the hinge mechanism in the middle, makes the connecting rod have four degrees of freedom in four directions (up, down, left, and right), ensuring that the two sections of the connecting rod can rotate relative to each other under a certain torque without loosening, and also has the function of limiting. In the process of deploying and retracting the intelligent high deployment ratio expansion cabin, it can adapt to the height changes of the road surface without causing jamming.

[0123] Specifically, the central controller is also connected to the electric support rod circuit, and the central controller can control the extension and retraction of the electric support rod.

[0124] Exemplarily, the central controller in the present invention is connected to the electric strut circuit, and the central controller can control the extension and retraction of the electric strut, and finally realize the deployment and folding of the intelligent high deployment ratio expansion cabin. Preferably, the design of the electric strut is the same as the electric road strut 92, and a motor is arranged inside the electric strut, and the motor can drive the electric strut to extend and retract. A Hall sensor is arranged inside the motor, and the Hall sensor is used to collect motor working information; a planetary reduction gear set and a worm gear are also arranged inside. The power output shaft of the motor is meshed with the sun gear in the planetary reduction gear set, and the planetary gear in the planetary reduction gear set is meshed with the worm gear, and the worm gear is used to drive the electric strut to extend and retract.

[0125] Specifically, the intelligent high-expansion-retraction ratio expansion cabin also includes a plurality of sensors, which are respectively connected to the connecting rod and the electric strut signal; the sensors can sense the horizontal condition of the connecting rod and obtain the connecting rod information; the sensors can sense the extension and retraction of the electric strut and obtain the strut information. The plurality of sensors are also connected to the central controller in communication, and the plurality of sensors transmit the connecting rod information and the strut information to the central controller.

[0126] Exemplarily, the intelligent high deployment ratio expansion cabin also includes a number of sensors, some of which are connected to the connecting rod signal and sense the horizontal condition of the connecting rod to obtain the connecting rod information. The horizontal condition of the connecting rod can reflect whether the cabin is stable during the current deployment and retraction; some of the sensors are connected to the electric strut signal and sense the extension and retraction of the electric strut to obtain the strut information. Some of the sensors are also communicatively connected to the central controller, and some of the sensors transmit the connecting rod information and the strut information to the central controller. The central controller can determine the condition of a certain connecting rod or electric strut based on the obtained connecting rod information and strut information, such as whether the deployment and retraction is in place, whether the deployment and retraction speed is too fast, etc. Through the integrated analysis of the connecting rod information and the strut information transmitted by the sensor, the central controller can better control the extension and retraction of the electric strut.

[0127] Specifically, when the central controller controls the electric support rod to extend and retract, the electric support rod is stuck, and the central controller controls the electric support rod to move in the opposite direction.

[0128] For example, the present invention takes into account the phenomenon of component jamming (such as the bottom plate jamming) during the process of extension and retraction, and applies reverse current on both sides at the same time (that is, the two electric struts driving the bottom plate to move in opposite directions), so that the component retreats a certain stroke and then re-expands, so that the system has a certain tolerance. When the central controller controls the electric strut to extend and retract, the electric strut jams, and the central controller controls the electric strut to move in the opposite direction.

[0129] Specifically, a driving motor is installed on both sides of the left three-stage expansion cabin 4 and the right three-stage expansion cabin 7, and a driving wheel is arranged under the driving motor, and the driving wheel can drive the left three-stage expansion cabin 4 and the right three-stage expansion cabin 7 to move.

[0130] Exemplarily, the intelligent high-expansion-and-retraction ratio expansion cabin designed by the present invention has an additional drive motor designed on both sides of the third-level frame, which serves as the power of the drive wheel to pull and push the expansion and retraction of each level of the expansion and retraction frame, so that the expansion and retraction cabin has sufficient power to ensure that the expansion and retraction mechanisms at each level can be smoothly expanded and retracted under various working conditions. A drive motor is installed on both sides of the left third-level expansion cabin 4 and the right third-level expansion cabin 7, and a drive wheel is arranged under the drive motor, and the drive wheel can drive the left third-level expansion cabin 4 and the right third-level expansion cabin 7 to move. When expanding, the drive wheel provides an outward pulling force, and when folding, the drive wheel provides an inward thrust. Preferably, the drive wheel can be a guide wheel in a road surface adaptive device, and the drive motor can be a motor in the road surface adaptive device. In this case, the output power of the drive motor is greater than that of the motor in the original road surface adaptive device.

[0131] Specifically, sealing components are arranged around each plate of the main cabin 1, the left first-level expansion cabin 2, the left second-level expansion cabin 3, the left third-level expansion cabin 4, the right first-level expansion cabin 5, the right second-level expansion cabin 6, and the right third-level expansion cabin 7. When the intelligent high expansion and contraction ratio expansion cabin is unfolded, the sealing components of each plate can cooperate to seal the intelligent high expansion and contraction ratio expansion cabin.

[0132] Exemplarily, the intelligent high-expansion-retraction ratio expansion cabin designed by the present invention has a sealing structure design. The top plate, bottom plate, side plate, front plate and rear plate in each cabin are all provided with sealing components. Preferably, the parts that move when expanding and retracting in the intelligent high-expansion-retraction ratio expansion cabin are all provided with sealing components; such as the left-level expansion top plate, the left-level expansion front plate, the left-level expansion rear plate and the left-level expansion bottom plate in the left-level expansion cabin 2, such as the right-level expansion top plate, the right-level expansion front plate, the right-level expansion side plate, the right-level expansion rear plate and the right-level expansion bottom plate of the right-level expansion cabin 7. The main front plate, the main rear plate, the main top plate and the main bottom plate of the main cabin 1 can be set as one piece, and there is no need to set a sealing component, or only need to set a sealing component at the connection between the main cabin 1 and the left-level expansion cabin 2 and the right-level expansion cabin 5. When the intelligent high-expansion-retraction ratio expansion cabin is unfolded, the sealing components of each plate can cooperate to seal the intelligent high-expansion-retraction ratio expansion cabin.

[0133] Specifically, a sound device is provided inside the intelligent high-expansion-and-sleeping ratio expansion cabin, and a warning light device is provided outside the intelligent high-expansion-and-sleeping ratio expansion cabin; when the intelligent high-expansion-and-sleeping ratio expansion cabin is expanded or folded, the sound device emits a sound and the warning light device flashes.

[0134] Exemplarily, the present invention takes into account the relevant safety design: a sound device is provided inside the intelligent high-expansion-retraction ratio expansion cabin, and a warning light device is provided outside the intelligent high-expansion-retraction ratio expansion cabin; when the intelligent high-expansion-retraction ratio expansion cabin is expanded or folded, the sound device emits a sound, and the warning light device flashes. The sound of the sound device and the flashing effect of the warning light device can be pre-designed.

[0135] The present invention also designs an intelligent high-expansion-and-retraction ratio expansion and retraction method for a shelter, which includes a shelter deployment method and a shelter folding method;

[0136] The shelter deployment method comprises:
