Description

Technical Field

[0001] This utility model relates to the field of modular housing equipment technology, and more specifically, to a modular housing quick-folding and telescopic mechanism with linkage support. Background Technology

[0002] A modular, rapidly deployable container-type work area is constructed from robust materials and possesses protective, mobile, and environmentally adaptable features, making it widely used in military, medical, and emergency support fields. As a transportable, independent cabin, its core characteristics are high mobility (suitable for various modes of transport such as road, rail, and air) and rapid loading and unloading. To facilitate transportation and rapid deployment, some modular containers are designed as expandable units, which can be folded to reduce volume during transport and quickly expanded to increase space during deployment.

[0003] Traditional expandable modular units, such as four-panel linkage structures (side top panel, side upper panel, side lower panel, and side bottom panel), can be folded up and unfolded by sliding. However, for the sake of structural stability, they are generally only equipped with a single auxiliary compartment. After the auxiliary compartment is extended, its expansion area is not large.

[0004] The Chinese utility model patent, which has been published and is titled "A Foldable Extendable Container" with publication number CN206086509U, includes a container body with side compartments on both sides. Each side compartment includes a side compartment folding and extending device and a side compartment telescopic support device. This utility model features fast expansion speed, large expansion area, and high stability.

[0005] Although this utility model can quickly expand the side cabin and use telescopic support devices to support the side cabin, because its side cabin area is large and the support surface is small, when the side cabin and its internal facilities are too heavy, the weight can easily cause the bottom of the side cabin to collapse and deform, resulting in low safety and low support stability. Summary of the Invention

[0006] The purpose of this application is to provide a rapid folding and telescopic mechanism for modular shelters with linkage support, which solves the technical problem of expanding multi-level folding sub-cabins and providing stable support when the area of ​​the folding sub-cabins is too large.

[0007] To solve the above-mentioned technical problems, the solution adopted in this application is as follows: A modular support quick-folding and telescopic mechanism for a container includes a main frame, with folding frames on both sides of the main frame. The folding frames are telescopic structures, and their telescopic direction is along both sides of the main frame.

[0008] Preferably, the folding frame includes a primary main frame and multiple secondary frames, which are arranged in a tower-like structure and slide sequentially along both sides of the main frame.

[0009] Preferably, bottom frame plates are hinged to the lower sides of the main frame, and the bottom frame plates are matched vertically with the folding frame, and the bottom frame plates are laid flat.

[0012] Preferably, the bottom frame is hinged to the bottom frame of the main frame via hinges.

[0013] Preferably, the bottom shelf is folded towards the side of the main frame, and when the folded frame is not extended, the bottom shelf is fitted against the side of the main frame.

[0014] Preferably, the bottom frame and the main frame are connected by a telescopic drive component.

[0015] Preferably, the fixed end of the telescopic drive component is hinged to the main frame, the telescopic end of the telescopic drive component is hinged to the bottom frame plate, and the hinge point between the telescopic electric cylinder and the main frame is higher than the hinge point between the telescopic electric cylinder and the bottom frame plate.

[0016] Preferably, the support frame includes reinforcing bars.

[0017] Preferably, two ribs are symmetrically arranged below the bottom frame plate, the ribs abut against the lower surface of the bottom frame plate, and one end of the ribs is hinged to the lower part of the main frame, with the hinge direction perpendicular to the hinge direction of the bottom frame plate.

[0018] Preferably, the support frame further includes a positioning rod, which is in the shape of a door.

[0019] Sleeves are fixedly installed on the rib frame and the lower part of the main frame.

[0020] Preferably, a guide structure is also provided between the folding cabin frame and the bottom frame plate, the guide structure including pulleys and guide bars.

[0021] Preferably, the bottom of the main body and the multiple auxiliary bodies are provided with free-rolling pulleys, and the upper surface of the bottom frame is fixed with guide strips. The guide strips correspond to and match the pulleys, and the length direction of the guide strips is consistent with the rolling direction of the pulleys.

[0022] Preferably, the plurality of sub-cabins and the main cabin are provided with a locking structure, which includes a locking pin and a slot.

[0023] Preferably, the sliding front ends of the main body and the multiple sub-body are respectively fixed with locking pins and slots, and the shapes of the locking pins and slots are matched.

[0024] Preferably, the locking pins and slots between adjacent compartments are staggered and corresponding.

[0026] Preferably, the bottom frame plate is also provided with an openable hatch, corresponding to the hatch on the side of the auxiliary compartment.

[0027] The technical solution of this application has at least the following advantages and beneficial effects: In this utility model, the folding cabin frame is set as a tower-like structure of multi-level sub-cabins. The expansion area of ​​the cabin is increased by using multi-level telescopic cabins. In order to solve the problem of collapse and deformation caused by excessive expansion area, a flat bottom frame is set at the bottom. The bottom frame supports the bottom surface of the multi-level cabins by using the surface support of the bottom frame to reduce the deformation of the cabin. To address the issue of reducing the cabin area when it is expanded and then retracted, the bottom frame is designed to be foldable, fitting snugly against the main body of the cabin to reduce its volume. Furthermore, to improve the load-bearing stability of the bottom frame, foldable stiffeners are installed below it. The two frames are folded perpendicularly and can work together to provide support, thereby improving the load-bearing effect and enhancing the stability of the folded cabin.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] It should be noted that similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. The terms "center," "upper," "lower," "inner," and "outer," indicating orientation or positional relationships based on the orientation or positional relationships shown in the figures, or the orientation or positional relationships commonly used when the product is in use, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation on this application. It should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] Example 1 Please refer to Figures 1-6 This utility model provides a linkage-supported quick-folding and telescopic mechanism for a container, including a main frame 1, with each frame of the main frame 1 fixedly connected. Folding frames 4 are respectively provided on both sides of the main frame 1. The folding frames 4 are telescopic structures that can extend or retract along both sides of the main frame 1 to increase the spatial volume of the entire container structure.

[0038] In order to increase the expansion volume of the entire modular structure, the folding frame 4 includes a primary main body 401 and multiple secondary bodies 402. The primary body 401 is slidably connected to the side frame of the main frame 1, and the secondary bodies 402 are slidably connected to the side frame of the primary body 401. Adjacent secondary bodies 402 are also slidably nested and connected to each other, so that the primary main body 401 and the multiple secondary bodies 402 form a tower-like structure in sequence, thereby realizing the folding frame 4 sliding outward from the side of the main frame 1 in sequence.

[0039] It is worth noting that after the multi-level sub-cabin 402 extends and slides into place, it is necessary to temporarily fix the extended state of the multi-level sub-cabin 402 to reduce the occurrence of it sliding out and detaching at will. Therefore, a stop is provided at the sliding end of the main cabin 401 and the sub-cabin 402. When the main cabin 401 or the sub-cabin 402 slides out to the sliding end, the stop at the sliding end will abut against the cabin frame that matches it, thereby restricting the continued sliding of the main cabin 401 or the sub-cabin 402, thus maintaining the extended state of the folding cabin frame 4.

[0040] Furthermore, since the folding frame 4 is equipped with multi-level sub-frames 402, when the multi-level sub-frames 402 are extended, their extension space expands, and the bottom area of ​​the entire container structure also increases. The main frame 1 alone cannot support the extended folding frame 4. In particular, when staff arrange furniture or facilities in the container, the folding frame is prone to collapse and deformation due to its weight. Its structure is easily damaged, and it is also easy to lose its folding function due to deformation.

[0041] Therefore, in order to solve the above problems, a more stable and safer support structure is needed for the multi-level sub-cabinet 402 of the folding cabin frame 4.

[0042] Please refer to Figures 1-4 In this embodiment, bottom frame plates 201 are respectively provided on both sides of the main frame 1, corresponding to the folding frame 4. When the bottom frame plates 201 are laid flat and the folding frame 4 is extended, the bottom frame plates 201 can support the entire folding frame 4. The support surface of the bottom frame plates 201 supports the folding frame 4, reducing the possibility of the folding frame 4 collapsing or deforming due to its weight.

[0043] Specifically, the support frame 2 includes a bottom frame plate 201 and a hinge 202.

[0044] The bottom frame 201 is hinged to the bottom frame of the main frame 1 via a hinge, allowing the bottom frame 201 to be folded at an angle relative to the main frame 1.

[0045] When the folding frame 4 is not extended, the folding frame 4 is retracted into the main frame 1. At this time, the bottom frame 201, which is laid flat on the outside of the main frame 1, occupies a large space and has a certain impact on the transportation and placement of the container (the overall volume of the container is too large). Therefore, the bottom frame 201 is hinged to the main frame 1 so that when the folding frame 4 is not extended, the bottom frame 201 can be folded at an angle and fit against the side of the main frame 1, thereby reducing the volume of the entire container structure.

[0046] When the folding frame 4 is extended, the multi-stage sub-frames 402 of the folding frame 4 extend. At this time, in order to support the extended folding frame 4, the bottom frame plate 201 needs to be pre-extended at an angle and laid flat on the outside of the main frame 1. In order to improve the flatness of the bottom frame plate 201 and reduce its interference with the extension of the folding frame 4 (when the bottom frame plate 201 is tilted, it is easy to interfere with the laterally extending and sliding sub-frames 402 on it), the bottom frame plate 201 and the main frame 1 are connected by a telescopic drive 3. The telescopic drive 3 automatically controls the angle folding range of the bottom frame plate 201 to improve the flatness.

[0047] The telescopic drive component 3 is a telescopic electric cylinder. The cylinder body of the telescopic electric cylinder is hinged on the main frame 1. The telescopic end of the telescopic electric cylinder is hinged to the bottom frame plate 201. The hinge point between the telescopic electric cylinder and the main frame 1 is higher than the hinge point between the telescopic electric cylinder and the bottom frame plate 201, so that the telescopic electric cylinder can drive the bottom frame plate 201 to fold at an angle toward the side of the main frame 1.

[0048] After the bottom frame plate 201 is installed, the entire weight of the folding cabin frame 4 will be borne on the bottom frame plate 201. By utilizing the flat surface of the bottom frame plate 201, the occurrence of collapse and deformation of the folding cabin frame 4 can be reduced, thereby improving the stability and safety of the entire cabin structure.

[0049] Furthermore, although the bottom frame 201 provides support, reducing the probability of the folding cabin frame 4 collapsing or deforming, the bottom frame 201 is hinged to the main cabin frame 1 and controlled by the telescopic drive assembly. Therefore, when the bottom frame 201 provides support, the weight borne by the bottom frame 201 will act on its hinge points and the telescopic drive assembly it is connected to, causing these connection parts to bear excessive stress, which can easily lead to their breakage and damage, affecting the functionality of the cabin structure.

[0050] To solve the above problems, please refer to Figures 4-5 In this embodiment, support ribs 7 are respectively provided on both sides of the main frame 1, corresponding to the support frame surface 2. The support ribs 7 are located below the support frame surface 2 and are used to provide linkage support for the support frame surface 2.

[0051] Specifically, the support frame 7 includes a rib 701, a hinge seat 702, and a positioning rod 703.

[0052] Two ribs 701 are symmetrically arranged below the bottom frame plate 201. The ribs 701 abut against the lower surface of the bottom frame plate 201, and one end of the ribs 701 is hinged to the lower part of the main frame 1 through the hinge seat 702 (the hinge seat 702 is fixed on the main frame 1). The hinge direction is perpendicular to the hinge direction of the bottom frame plate 201. This allows the ribs 701 to be folded at an angle on the main frame 1 while also supporting the entire bottom frame plate 201 and the folding frame 4 on it. The ribs 701 can distribute the weight to the main frame 1 through their hinge points, thereby linking with the bottom frame plate 201 to support the entire folding and telescopic frame 4, increasing the stability of the support position.

[0053] Moreover, modular shelters are generally used as emergency facilities and are usually set up in the external environment. Their bottom is usually erected on the ground. However, the ground in the field is uneven and rugged. If the entire bottom frame 201 is laid directly on the ground, it is easy for the folding frame 4 on it to be deformed due to force when it extends and slides, resulting in sliding resistance (the bottom frame 201 cannot be laid flat), making it difficult to extend and fold. Therefore, setting a rib frame with a small contact area to contact the ground can improve the flatness of the bottom frame 201 above, thereby improving the smoothness of the extension of the folding frame 4.

[0054] Because the two symmetrically arranged stiffeners will interfere with each other due to their length when they are folded synchronously toward the main frame 1 (after the folded frame 4 is retracted, the stiffeners also need to be folded to reduce the volume of the container), in order for the two stiffeners to be folded onto the main frame 1, the hinge points of the connecting hinge seats 702 are staggered and correspondingly arranged so that the two stiffeners will be folded in an alternating manner without interference.

[0055] The folding angle of the frame is free after the angle adjustment of the hinge seat 702. Therefore, in order to ensure the stability of the cabin, its support position needs to be restricted. Therefore, sleeves are fixedly installed on the frame and the lower part of the main cabin frame 1. When the folding cabin frame 4 is extended and the bottom frame plate 201 is laid flat, the frame supports the bottom frame plate 201. The positioning rod 703 connects the frame and the bottom frame plate 201. The positioning rod 703 is in the shape of a door. The two ends of the positioning rod 703 are respectively sleeved in the sleeves on the frame and the main cabin frame 1 to fix the angle position of the frame and the main cabin frame 1. When the folding cabin frame 4 is retracted, the positioning rod 703 can be manually removed from the sleeve to allow the frame to return to its free swing state.

[0056] It is worth noting that the outermost side of the sub-cabin 402 in the folding frame 4 is also provided with an openable hatch 403, which facilitates personnel to enter and exit the entire container. When the entire folding frame 4 is folded and retracted to the main frame 1, the outer bottom frame 201 and ribs 701 will fold and fit against the side of the main frame 1. At this time, the surface of the bottom frame 201 will block the hatch 403 on the side of the sub-cabin 402. Therefore, an openable hatch 403 is also provided on the bottom frame 201, corresponding to the hatch 403 on the side of the sub-cabin 402.

[0057] Example 2 During the extension of the folding cabin frame 4, the bottom frame plate 201 is already in a flat state through the telescopic drive component 3. At this time, the bottom of the sub-cabin body 402 of the folding cabin frame 4 will rub against the upper surface of the bottom frame plate 201. Due to the weight of the sub-cabin body 402, the frictional resistance will be large, making the extension not very smooth. Therefore, in order to improve the smoothness of the extension of the folding cabin frame 4, a guide structure 5 is also provided between the folding cabin frame 4 and the bottom frame plate 201 to provide extension sliding guidance and reduce frictional resistance.

[0058] Specifically, the guide structure 5 includes a pulley 501 and a guide bar 502.

[0059] The bottom of the main body 401 and multiple auxiliary bodies 402 are all fixedly equipped with pulleys 501, which can roll freely. The upper surface of the bottom frame plate 201 is fixed with guide strips 502, which correspond to and match the pulleys 501, and the length direction of the guide strips 502 is consistent with the rolling direction of the pulleys 501.

[0060] When the main cabin 401 and multiple auxiliary cabins 402 are extended, the pulleys 501 at their bottom will roll along the guide strips 502, changing the sliding friction between the main cabin 401, multiple auxiliary cabins 402 and the bottom frame plate 201 into rolling friction, thereby reducing frictional resistance and improving the smoothness of the extension of the folding cabin frame 4.

[0061] Example 3 Because the retraction displacement of multiple sub-cabins 402 is unrestricted when the folding frame 4 is retracted, it is easy for them to retract excessively or even detach from the main frame 401, making it difficult for staff to retract the sub-cabins 402. Therefore, a locking structure 6 is also provided on the multiple sub-cabins 402 and the main frame 401 to restrict and position the retraction position of the multiple sub-cabins 402 when the folding frame 4 is retracted, so that staff can quickly and neatly retract the folding frame 4 into the main frame 1.

[0062] Specifically, the locking structure 6 includes a locking pin 601 and a slot 602.

[0063] Please refer to Figure 3The sliding front ends of the main cabin 401 and multiple sub-cabins 402 are respectively fixed with locking pins 601 and slots 602. The shapes of the locking pins 601 and slots 602 are matched and engaged. The locking pins 601 and slots 602 between adjacent sub-cabins 402 (or adjacent sub-cabins 402 and main cabin 401) are staggered and corresponding. When adjacent cabins retract, the locking pins 601 and slots 602 of adjacent cabins are matched and engaged together, locking them together and allowing them to slide together. When the main cabin 401 and multiple sub-cabins 402 are all locked together by locking pins 601 and slots 602, they can slide together and retract neatly into the main cabin frame 1, thereby improving the folding efficiency of the cabin.

[0064] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
