Description

Technical Field

[0001] This invention belongs to the field of modular equipment, specifically relating to an extended modular container. Background Technology

[0002] Traditional expandable modular shelters come in two forms: one is the panel-type expandable shelter, which includes flip-up and pull-out types, with the expandable parts being assembled from panel components that are folded and stored in the main body of the shelter; the other is the tent-type expandable shelter, with the expandable parts consisting of tents, which are fixed to the main body of the shelter by connectors.

[0003] The panel-type expandable cabin has heavy panel components, which makes transportation, storage and handling inconvenient. Moreover, its external size is limited by the volume of the main cabin and cannot be made larger, resulting in a small space for the expandable part. The tent-type expandable cabin has a relatively independent tent and cabin body. When it is folded up, the tent parts are disassembled and stored in the cabin body. When it is unfolded, the parts are assembled one by one to form the tent and then connected to the cabin body. This form is not only prone to the loss of tent parts, but also the folding and unfolding process is cumbersome and time-consuming. In addition, the connection between the tent and the cabin body is not airtight and can easily cause air and rain leaks.

[0004] Therefore, a new type of expandable container is needed to solve the problems of heavy weight and limited deployment space of panel-type expandable containers, as well as the problems of easy loss of accessories, cumbersome folding and unfolding process, and poor sealing of tent-type expandable containers. Summary of the Invention

[0005] To address the problems of the existing technology, this invention provides an expandable cabin that organically combines a tent and the cabin body. When collapsed, the tent body can be folded and stored inside the cabin body; when unfolded, the tent body can extend to the outside of the cabin, avoiding the disassembly and assembly process of the tent body. Furthermore, the connection between the tent and the cabin body employs a superior sealing structure. This invention aims to solve the problems of heavy weight and limited unfolding space in panel-type expandable cabins, as well as the issues of easily lost accessories, cumbersome folding and unfolding processes, and poor sealing in tent-type expandable cabins. The specific details of this invention are as follows.

[0006] An extended modular housing includes a main housing body and a tent.

[0007] The main body of the modular shelter is hollow, and its side walls are fitted with side panels that can be unfolded outwards. When unfolded, the side panels form the floor of a tent that is parallel to and at the same height as the bottom wall of the main body of the shelter.

[0008] The tent is a retractable frame structure, consisting of a canopy and several portal frames. When extended, the tent forms its main body on the floor; when retracted, it is stored inside the main body of the container house. Each portal frame includes two vertical poles on either side and a horizontal pole in the middle, arranged parallel to the front-to-back direction of the container house. Several portal frames are connected sequentially by X-shaped rods. Each X-shaped rod consists of two connecting rods hinged together in the middle. The upper end of each connecting rod is fixedly connected to a vertical pole of the portal frame, and the lower end of each connecting rod is slidably connected to the vertical pole on the same side of the adjacent portal frame.

[0009] The tarpaulin is stored inside the main body of the container. After the tent is extended, the tarpaulin is laid out and secured to the tent body. A first fastener is located on the side of the tarpaulin closest to the main body of the container, and a second fastener is located on the inner side of the main body of the container closest to the tent wall. After the tent is extended, the first and second fasteners work together to form a sealing strip.

[0010] In one implementation, the side panel is a two-stage outward-deploying structure, comprising a primary panel and a secondary panel. The lower side of the primary panel is hinged to the lower end of the main side wall of the shelter. The upper sides of the primary and secondary panels are hinged to each other and overlap to form the side panel. In the primary deployment state, the primary and secondary panels together rotate 90° downwards and outwards from the main body of the shelter. In the secondary deployment state, in the primary deployment state, the secondary panel rotates another 180° outwards from the hinge point, with the primary and secondary panels arranged horizontally to form the bottom panel.

[0011] In one implementation, a tilting assist mechanism is provided between the first-stage panel and the main body of the container. The tilting assist mechanism is a columnar elastic structure, with one end hinged to the side of the first-stage panel and the other end hinged to the side wall of the main body of the container, used to provide assistance to the operators during the unfolding and retraction of the side panel.

[0012] In one implementation, the main body of the modular tent has a first track on its bottom wall. A second track is located on the upper surface of the bottom plate. The first and second tracks can be connected end-to-end to form a complete track. A slider is located at the lower end of the vertical pole. When the tent is retracted, the slider engages with the first track, and the slider is fixed to the first track by a locking mechanism installed between the slider and the first track. The complete track and slider guide the portal frame when the tent is extended.

[0013] In one implementation, the primary and secondary plates are hinged together by torsion spring hinges. The torsion spring hinges provide assistance to the operator during the secondary deployment and provide cushioning when the secondary plate rotates 180° inward toward the main body of the container in the secondary deployment state.

[0014] In one implementation, jacks are installed on the lower sides of both the first-stage and second-stage deployed tents, away from the main body of the tent. These jacks are used to support and level the tent.

[0015] In one implementation, the lower end of the X-shaped pole is slidably connected to the vertical pole via a sliding sleeve with a first locking pin. A first locking hole is located in the middle of the vertical pole. When the tent is retracted, the several portal frames move closer together, and both the upper and lower ends of the X-shaped pole are clamped together. The sliding sleeve is located below the first locking hole, and the locking pin is in the unlocked state. When the tent is extended, the several portal frames move further apart, and both the upper and lower ends of the X-shaped pole are separated. The sliding sleeve, driven by the X-shaped pole, moves upward to the position of the first locking hole. The locking pin is in the locked state and engages with the first locking hole to fix the lower end of the X-shaped pole to the vertical pole.

[0016] In one embodiment, the vertical rod includes a lower support rod and an upper telescopic rod. The telescopic rod is fitted over the support rod, and a second locking pin is located at its lower end. A second locking hole is located at the upper end of the support rod, above the second locking pin. The telescopic rod can move upward along the support rod, and the second locking pin engages with the second locking hole to fix the telescopic rod to the support rod.

[0017] In one implementation, the tarpaulin includes an inner tarpaulin and an outer tarpaulin. The inner tarpaulin is laid inside the portal frame, and the outer tarpaulin is laid outside the portal frame. A first fastener is located on the side of the inner tarpaulin near the main body of the container. A matching hook and a matching Velcro are provided between the side of the outer tarpaulin near the main body of the container and the outer side wall of the container near the tent. The hooks and Velcro are used for connecting and securing the tent to the main body of the container.

[0018] In one implementation, two tents are used. Two sets of side panels and a first track are also used, both positioned on the left and right sides of the main body of the container. When retracted, the two tents are positioned on the left and right sides inside the main body of the container. When extended, the two tents are positioned on the left and right sides outside the main body of the container.

[0019] The beneficial effects of this invention are that the main body of the modular shelter is equipped with side panels that can form the floor of a tent, allowing the tent to be organically integrated with the main body of the shelter. The tent is no longer a relatively independent piece of equipment but is integrated with the main body of the shelter, and its multi-functional design reduces the number of tent accessories. The retractable tent design simplifies the tent structure, eliminates the need for disassembly and assembly, and prevents the loss of accessories. The sealing strip between the tent fabric and the main body of the shelter effectively solves the overall sealing problem of the extended shelter, and the simple structure and convenient operation save various resources.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] refer to Figures 1-9 The present invention provides an extended cabin, comprising a cabin body 1 and a tent 3.

[0036] like Figure 1 , Figure 2 As shown, the interior of the main body 1 of the shelter is hollow, and its side walls are equipped with side panels 2 that can be unfolded outwards. After unfolding, the side panels 2 form the bottom plate of the tent 3, which is parallel to and at the same height as the bottom wall of the main body 1 of the shelter.

[0037] like Figure 2 As shown, tent 3 is a retractable canopy structure, including a canopy and several portal frames 301. When extended, tent 3 forms the main body of the tent on the base plate; when retracted, it is stored inside the main body of the container house 1. The portal frames 301 include vertical poles on both sides and a horizontal pole 305 in the middle, and are arranged parallel to the front-to-back direction of the main body of the container house 1. It should be noted that the upper ends of the vertical poles and the lower ends of the horizontal poles 305 are riveted together.

[0038] like Figure 5As shown, several portal frame supports 301 are connected sequentially by X-shaped rods 302. Each X-shaped rod 302 includes two connecting rods hinged together at their midpoints. The upper end of each connecting rod is fixedly connected to the vertical rod of the portal frame 301, preferably by screws or rivets, and the lower end is slidably connected to the vertical rod on the same side of the adjacent portal frame 301, preferably by a sliding sleeve. It should be noted that the two connecting rods of the X-shaped rod 302 can swing up and down around the hinge point as the tent 3 contracts and expands.

[0039] The tarpaulin is stored inside the main body 1 of the container house. After the tent 3 is extended, the tarpaulin is laid out and fixed to the main body of the tent 3, preferably using a structure of holes and hooks for fixation. A first fastener is provided on the side of the tarpaulin closest to the main body 1 of the container house, preferably fixed to the tarpaulin by sewing. A second fastener is provided on the inner side wall of the main body 1 of the container house closest to the tent 3, preferably fixed by riveting. After the tent 3 is extended, the first and second fasteners cooperate to form a sealing strip 311. Preferably, the first and second fasteners use the hook side and the fleece side of Velcro.

[0040] In practical implementation, the main body 1 of the modular cabin is equipped with side panels 2, which can form the base of the tent 3, allowing the tent 3 to be organically integrated with the main body 1. The tent 3 is no longer a relatively independent piece of equipment, but is integrated with the main body 1, and its multi-functional design reduces the number of accessories required for the tent 3. The retractable tent 3 simplifies its structure, eliminates the need for disassembly and assembly, and prevents the loss of accessories. The sealing strip 311 between the tent fabric and the main body 1 effectively solves the overall sealing problem of the extended modular cabin, and its simple structure and convenient operation save various resources.

[0041] According to specific embodiments of the present invention, such as Figure 3 , Figure 4 As shown, side panel 2 is a two-stage outward-expanding structure, having a first-stage and a second-stage unfolding state, including a first-stage panel 201 and a second-stage panel 202. The lower side of the first-stage panel 201 is hinged to the lower side wall of the main body 1 of the shelter. The upper sides of the first-stage panel 201 and the second-stage panel 202 are hinged to each other and overlap to form side panel 2. In the first-stage unfolding state, the first-stage panel 201 and the second-stage panel 202 together rotate 90° downwards and outwards from the main body 1 of the shelter. In the second-stage unfolding state, in the first-stage unfolding state, the second-stage panel 202 rotates outwards again by 180° around the hinge point, and the first-stage panel 201 and the second-stage panel 202 are arranged horizontally to form a bottom panel. It should be noted that when the first-stage panel 201 and the second-stage panel 202 are overlapping to form side panel 2, the first-stage panel 201 and the second-stage panel 202 are fixed together by a latch 206.

[0042] In practice, by unfolding the first-level plate 201 and the second-level plate 202 in two stages, a larger unfolding base plate can be obtained, which makes the volume of the container larger after expansion, and the volume of the side plate 2 after it is formed is small and will not occupy a larger internal storage space of the container.

[0043] One embodiment provided by the present invention is as follows: Figure 7 As shown, a tilting assist mechanism 204 is provided between the first-stage plate 201 and the main body of the container 1. The tilting assist mechanism 204 is a columnar elastic structure, with one end hinged to the side of the first-stage plate 201 and the other end hinged to the side wall of the main body of the container 1. It is used to provide assistance to the operator during the unfolding and retraction of the side plate 2, that is, to provide assistance to the operator during the unfolding of the first stage and during the 90° tilting of the side plate 2 from the unfolded state to the inside of the main body of the container 1.

[0044] It should be noted that the flipping assist mechanism 204 consists of an outer cylinder 2044, an inner cylinder 2043, a pull ring 2041, and an assist spring 2042. It is used to counteract the impact of its own gravity generated during the first stage of unfolding, and to prevent the first stage plate 201 and the second stage plate 202 from falling directly to the ground and causing mechanical damage. When retracting, the pulling force of the assist spring 2042 can reduce the physical exertion of personnel.

[0045] In practice, the flipping assist mechanism 204 can provide assistance to the operator through the tension of the assist spring 2042 when unfolding and retracting, and can reduce impact damage to components.

[0046] According to embodiments of the present invention, such as Figure 5 As shown, the bottom wall of the main body 1 of the shelter has a first track 205. The upper surface of the bottom plate has a second track 208. Both the first track 205 and the second track 208 are fixed to the bottom wall and bottom plate by rivets or screws, and the two can be connected end to end to form a complete track. The lower end of the vertical rod has a slider 309, which is preferably fixed to the lower end of the vertical rod by rivets or screws. After the tent 3 is retracted, the slider 309 cooperates with the first track 205, and the slider 309 is fixed to the first track 205 by a locking mechanism installed between the slider 309 and the first track 205. The locking mechanism can preferably adopt a locking structure in the prior art, such as a locking pin and hole fit. The complete track and the slider 309 guide the portal frame 301 when the tent 3 is extended. It should be noted that when the tent 3 is extended, the sliders 309 of several portal frames 301 cooperate with the complete track and slide out from the inside of the main body 1 of the shelter along the track in sequence under human force.

[0047] As another embodiment, the slider 309 can be replaced with a roller structure that cooperates with the track, so that sliding friction is converted into rolling friction with a smaller coefficient of friction.

[0048] In practice, the structure of the slider 309 and the track makes the tent 3 more convenient and less strenuous to extend, and the track plays a guiding role in both the extension and retraction of the tent 3, which can prevent the tent 3 structure from deforming.

[0049] One embodiment provided by the present invention is as follows: Figure 3 , Figure 4 As shown, the primary plate 201 and the secondary plate 202 are hinged together by a torsion spring hinge 203. The torsion spring hinge 203 provides assistance to the operator during the secondary deployment and provides cushioning when the secondary plate 202 rotates 180° inward towards the main body of the shelter in the secondary deployment state. It should be noted that, as Figure 9 As shown, the torsion spring hinge 203 includes a hinge 2033, a hinge shaft 2036, a retainer 2034, a bushing 2031, a torsion spring 2032, and a retaining ring 2035. The hinge 2033 is fixedly connected to the primary plate 201 and the secondary plate 202. The two ends of the torsion spring 2032 are fixed to the hinge 2033 by the retainer 2034, which can be welded or riveted, and provides elastic force. The hinge shaft 2036 is located at the center of the torsion spring 2032, and the hinge shaft 2036 is fixed to the bushing 2031 by the retaining ring 2035.

[0050] In practice, the torsion spring hinge 203 can effectively reduce the physical exertion of personnel during the secondary unfolding process and can also play a certain buffering role when the secondary plate 202 is retracted.

[0051] According to an embodiment of the present invention, Figure 5 As shown, in both the first-stage and second-stage deployed states, jacks 207 are arranged on the lower side of the first-stage plate 201 away from the main body 1 and on the lower side of the second-stage plate 202 away from the main body 1. The jacks 207 are used to support and level the tent 3. Preferably, the jacks are in the form of a nut and screw, which is convenient to use and has a simple structure.

[0052] One embodiment provided by the present invention is as follows: Figure 5As shown, the lower end of the X-shaped rod 302 is slidably connected to the vertical rod via a sliding sleeve 303 with a first locking pin. A first locking hole is located in the middle of the vertical rod. When the tent 3 is retracted, several portal frame supports 301 move closer together, the upper and lower ends of the X-shaped rod 302 are clamped together, the sliding sleeve 303 is located below the first locking hole, and the locking pin is in the unlocked state. When the tent 3 is extended, the several portal frame supports 301 move further apart, the upper and lower ends of the X-shaped rod 302 are separated, and the sliding sleeve 303 moves upward to the position of the first locking hole under the action of the X-shaped rod 302. The locking pin is in the locked state and cooperates with the first locking hole to fix the lower end of the X-shaped rod 302 to the vertical rod. It should be noted that fixing the sliding sleeve 303 to the vertical rod via the first locking pin is equivalent to fixing the lower end of the X-shaped rod 302 to the vertical rod. Since the upper end of the X-shaped rod 302 is fixed to the vertical rod, the portal frame brackets 301 cannot move relative to each other at this time, thus fixing the main structure of the tent 3. When it is necessary to retract the tent 3, the locking pin is set to the unlocked state again, which releases the fixed connection between the lower end of the X-shaped rod 302 and the vertical rod. At this time, the portal frame brackets 301 can move closer to each other, thereby realizing the retraction of the tent 3.

[0053] In practice, the structure of the sliding sleeve 303 and the locking pin enables the tent 3 to be locked after it is extended.

[0054] According to embodiments of the present invention, such as Figure 5 As shown, the vertical rod includes a lower support rod 307 and an upper telescopic rod 306. The telescopic rod 306 is fitted over the support rod 307, and a second locking pin 304 is located at its lower end. A second locking hole is located at the upper end of the support rod 307, above the second locking pin 304. The telescopic rod 306 can move upward along the support rod 307, and is fixed to the support rod 307 by the engagement of the second locking pin 304 and the second locking hole.

[0055] It should be noted that, as Figure 6 As shown, the first locking pin and the second locking pin 304 have the same structure, including a handle 3031, a body 3032, a locking nut 3034, a locking pin shaft 3035, and a return spring 3033. The locking pin is connected to a nut welded to the sliding sleeve 303 via a thread on the body 3032 and is secured with the locking nut 3034. The locking pin shaft 3035 is assembled with the handle 3031 as a whole, and the locking pin can be inserted or removed via the return spring 3033 and the body 3032. When the handle 3031 is rotated to the lower notch of the body 3032, the locking pin shaft is inserted into the first locking hole of the telescopic rod 306, and the telescopic rod 306 and the sliding sleeve 303 are locked. When the handle 3031 is rotated to the upper notch of the body 3032, the locking pin shaft 3035 is pulled out of the first locking hole, the sliding sleeve 303 can slide up and down along the telescopic rod 306, the tent 3 support is unlocked, and the tent 3 can be extended or retracted.

[0056] In practice, the height of the tent 3 is adjustable through the structure of the telescopic pole 306, the support pole 307, and the second locking pin 304, making the space larger after unfolding.

[0057] One embodiment provided by the present invention is as follows: Figure 8 As shown, the tarpaulin includes an inner tarpaulin 310 and an outer tarpaulin 308. The inner tarpaulin 310 is laid inside the portal frame 301, and the outer tarpaulin 308 is laid outside the portal frame 301. A first fastener is located on the side of the inner tarpaulin 310 near the main body 1 of the container. Between the side of the outer tarpaulin 308 near the main body 1 of the container and the outer side wall of the main body 1 near the tent 3, there are interlocking hooks 312 and interlocking hook-and-loop fasteners 313. Preferably, the hooks adopt a rivet and rope structure. The rivets are fixed to the main body 1 of the container and exposed at a certain distance. The ropes are fixed to the outer tarpaulin and can be hung on the rivet heads to form a fixed structure. The hooks adopt a Velcro structure, with the hook face peaked on the outer tarpaulin and the fleece side riveted or glued to the main body of the container. The hooks 312 and hook-and-loop fasteners 313 are used for connection and fixation between the tent 3 and the main body 1 of the container. It should be noted that, due to the gap between the tent 3 and the main body 1 of the container, a transitional connection is made through the inner tarpaulin 310 and the outer tarpaulin 308. The connection between the inner tarpaulin 310 and the main body 1 of the container mainly serves a sealing function, while the connection between the outer tarpaulin 308 and the main body 1 of the container mainly serves a fixing function. In addition, a water-blocking bending component (not shown in the figure) is installed on the top of the main body 1 of the container to prevent rainwater from seeping in.

[0058] According to embodiments of the present invention, such as Figure 2 As shown, two tents 3 are provided. Two sets of side panels 2 and the first track 205 are also provided, and both are arranged on the left and right sides of the main body 1 of the shelter. When retracted, the two tents 3 are arranged on the left and right sides inside the main body 1 of the shelter. When extended, the two tents 3 are arranged on the left and right sides outside the main body 1 of the shelter.

[0059] In practice, setting up two sets of tents 3 can effectively increase the expansion space and provide more functional areas for the mobile cabin.
