Description

Technical Field

[0001] This utility model relates to the field of modular container equipment technology, and more specifically, to a modular container rapid expansion and docking mechanism suitable for various terrains. Background Technology

[0002] A mobile modular shelter is a portable, mobile living container structure equipped with basic living or working facilities; it can quickly provide living conditions for people in the external environment. It is commonly used in applications such as medical mobile shelters to respond to public health emergencies, or living support mobile shelters for disaster relief and rescue.

[0003] In existing technologies, for the resettlement of large numbers of people, a large number of modular cabins are placed together and connected. The existing modular cabins are generally connected by bolts or buckles to fasten the connection parts of two cabins together and set up a sealed structure. They are then installed in the external environment to resist the influence of natural environment such as wind, rain, and vibration.

[0004] However, in the actual docking process, due to the large size of the modular units and the difficulty of transportation, the two units are first placed together, then manually aligned, and finally the distance between the units is adjusted by the transport equipment to achieve accurate docking. However, due to the uneven ground in the environment where the units are placed, the units are easily obstructed when they are moved laterally. This makes the manual handling and alignment of the units time-consuming and laborious, and it is difficult to ensure accurate alignment. The uneven ground can also lead to incomplete matching of the docking positions, increased wear at the docking positions, and gaps that cannot be completely sealed. This can allow the internal space of the unit to connect with the external environment, affecting the normal life of the people inside the unit. Summary of the Invention

The two docking ends are then fixed together by a snap-fit ​​device. In particular, by setting an angle adjustment device and a rotation device between the hatch and the docking ends, the entire snap-fit ​​device can automatically adjust its lateral displacement without disengaging from the hatch, without causing the entire modular unit to shift, thus improving the convenience of adjustment. Furthermore, by driving the sensing device at the docking ends to sense the displacement, automatic sensing and alignment are achieved, improving docking accuracy and enabling rapid docking.

[0037] In this invention, a quick docking and fixing mechanism is achieved by setting a straight arm buckle and a docking cavity locking buckle. The elastic deformation structure of the straight arm buckle itself reduces the docking error between the docking positions of the two containers installed on uneven external ground, thus achieving a more accurate docking. Furthermore, by setting a rotatable straight arm buckle, when disengaging after docking, the straight arm buckle can be rotated to de-lock the docking cavity, thereby achieving quick disengagement.

Detailed Implementation

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.

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.

[0051] Example 1

[0052] Please refer to Figures 1-4 This utility model provides a rapid expansion and docking mechanism for modular shelters suitable for various terrains, including a connecting chamber, a sensing device 4, and a snap-fit ​​device 8.

[0053] Each of the modular units 7 has a connecting chamber at its docking end. When the modular units 7 are docked, the corresponding connecting chambers on the two docking modular units 7 are docked together. The sensing end and sensing end of the sensing device 4 are respectively set at the docking ends of the two connecting chambers to sense whether the two connecting chambers are docked accurately. The locking end and locking cavity of the locking device 8 are also respectively set at the docking ends of the two connecting chambers to lock the two connecting chambers together when they are docked.

[0054] In the prior art, gaps may appear between the docking ends of the two modular containers 7 due to uneven ground or transportation processes. When the two modular containers 7 dock, the gaps between the docking ends may cause gaps to exist between the two connecting chambers after docking. It may also cause the locking end and locking cavity of the locking device 8 to be difficult to lock together due to excessive spacing, making docking difficult.

[0055] Therefore, please refer to Figure 1 and Figure 2 In this embodiment, the connecting chamber includes a telescopic chamber 3, which is equipped with a telescopic device. The telescopic device is also wrapped with a tubular telescopic cover 302, and the space inside the telescopic cover 302 constitutes the space of the telescopic chamber 3.

[0056] Specifically, the telescopic end and the fixed end of the telescopic device are respectively fixedly connected to the two tubular ends of the telescopic cover 302. The two tubular ends of the telescopic cover 302 are respectively connected to the hatch 1 of the container 7 and the snap-fit ​​device 8. During the docking process of the two containers 7, the telescopic cover 302 in the two connecting chambers extends its tubular length through the extension of the telescopic device, so that the two telescopic covers 302 cancel the gap between them and fit together, thereby making the snap-fit ​​end of the snap-fit ​​device 8 on the two telescopic covers 302 snap-fit ​​and match with the snap-fit ​​cavity, improving the snap-fit ​​stability of the snap-fit ​​device 8.

[0057] In the existing technology, when two modular containers 7 are docked, the alignment accuracy of the two docking ends needs to be adjusted step by step. This process is generally done by manual observation, and the modular containers 7 are moved using a handling device to achieve alignment. However, this is time-consuming and labor-intensive, the adjustment time is long, and it is not easy to ensure the alignment accuracy through manual adjustment, resulting in low adjustment accuracy.

[0058] Therefore, please refer to Figure 1 and Figure 2 In this embodiment, the connecting chamber further includes an angle adjustment device 5 and a rotation device 6. The angle adjustment device 5 and the rotation device 6 are disposed between the container 7 and the telescopic chamber 3, and are used to adjust the position of the telescopic chamber 3, thereby adjusting the position of the locking device 8 on the telescopic chamber 3.

[0059] Specifically, the angle adjustment device 5 includes a swing plate 501 and a motor 502. One end of the swing plate 501 is rotatably mounted at the door 1 of the container 7, and the other end is rotatably mounted at one end of the telescopic cover 302 of the telescopic chamber 3. The motor 502 is fixed at the door 1 of the container 7, and its rotating shaft is fixedly connected to one end of the swing plate 501, thereby driving the swing plate 501 to swing angle. At the other end of the swing plate 501, a rotating device 6 is also fixedly mounted on the swing plate 501. The rotating device 6 is also a motor. The rotating end of the rotating device 6 is fixedly connected to the telescopic cover 302, driving the fixed cover to swing angle.

[0060] During the docking process of the two modular containers 7, the sensing devices 4 on the two docking ends are activated. The sensing end is set as a sensor 401, and the sensing head is set as a sensing head that can be sensed by the sensor 401. When the sensor 401 directly senses the sensing head, the sensing device 4 sends a signal to the controller. The controller controls the telescopic device to work, and the fast locking device 8 is achieved directly through the telescopic chamber 3. When sensor 401 does not detect the sensing head, the sensing device 4 sends a signal to the controller. The controller controls the motor 502 of the cabin 7 with the sensing end to work, and starts to drive the entire telescopic chamber 3 to swing by rotating the swing plate 501 (the devices on the other cabin 7 with the sensing end do not work). During the swing of the telescopic chamber 3, the rotating device 6 set on the swing plate 501 will drive the telescopic chamber 3 to rotate in the opposite direction by the same angle, which will counteract the angular swing of the swing plate 501. This makes the telescopic chamber 3 only affected by the offset generated by the swing plate 501, so that the telescopic chamber 3 only performs lateral displacement and does not swing. This allows the sensing end of the sensing device 4 to automatically align and sense the displacement.

[0061] During the docking process of the two modular containers 7, when the sensing end and the sensing end are aligned, the sensing device 4 sends a signal to the controller. The controller controls the telescopic device to work and controls the angle adjustment device 5 and the rotation device 6 to stop working. Then, the telescopic chamber 3 is telescopic to achieve precise alignment and locking of the locking device 8, thereby improving the locking accuracy.

[0062] Preferably, the angle adjustment device 5 and the rotation device 6 are used to achieve relative displacement of the two telescopic chambers 3, so that the sensing devices 4 on the two docking ends can sense the alignment and achieve the locking. The reason for not directly setting a horizontal displacement device between the container 7 and the telescopic chamber 3 is that the horizontal displacement device would directly change the position between the displacement end and the door 1 of the container 7, so that after docking, personnel cannot enter the telescopic chamber 3 through the door 1. By setting the angle adjustment device 5 and the rotation device 6, one end of the swing plate 501 is always located at the position of the door 1 of the container 7, reducing the possibility of the telescopic chamber 3 and the door 1 completely separating, so that the two containers 7 can lock together.

[0063] Example 2

[0064] In existing technologies, modular shelters are mostly set up in the external environment and form a living space inside the shelter, which is isolated from the external environment. Therefore, when modular shelters 7 are docked together, their docking parts (connecting chambers) also need to be isolated from the external environment.

[0065] Please refer to Figures 2-7 In this embodiment, the angle adjustment device 5 is set at the bottom of the transfer chamber 2. The bottom of the transfer chamber 2 is a base plate, which is fixed on the swing plate 501. A tubular telescopic cover 302 is fixed on the base plate. The telescopic cover 302 is used to form the space of the transfer chamber 2. The two ends of the telescopic cover 302 are fixedly connected to the hatch 1 and the telescopic chamber 3 respectively. When the swing plate 501 swings, the telescopic cover 302 can extend on one side and retract on the other side to adapt to the angular offset between the telescopic chamber 3 and the container 7.

[0066] Furthermore, to improve the stability of the telescopic chamber 3, the telescopic chamber 3 also includes a fixed frame 301 and a docking frame 303, both of which are frame-shaped structures. The fixed frame 301 is used to fix the telescopic cover 302 of the telescopic chamber 3 and the telescopic cover 302 of the transfer chamber 2, providing support for the two chamber spaces. The docking frame 303 is fixedly connected to the telescopic cover 302 at the docking end of the telescopic chamber 3, and is used to support the docking end, thereby supporting the sensing device 4 and the snap-fit ​​device 8 on the docking end.

[0067] The telescopic devices in the telescopic chamber 3 are also set on the fixed frame 301 and the docking frame 303 respectively. The telescopic devices drive the docking frame 303 to move, so that the docking frame 303 can extend and retract relative to the fixed frame 301, and the docking ends on the docking frames 303 of the two container docking frames can be engaged.

[0068] In addition, because a connecting chamber is provided at the hatch 1 of the modular container 7, the docking end is exposed to the external environment when the modular containers 7 are not docking. In order to ensure the airtightness of the modular container space, the chamber space of the connecting chamber also needs to be isolated from the external environment. Therefore, a sealable door 304 that can be opened and closed is also provided in the docking frame 303 to seal the docking end opening on the docking frame 303.

[0069] Example 3

[0070] Please refer to Figure 5 and Figure 6 In order to enable the telescopic device to extend and retract along the tubular length of the telescopic cover 302, in this embodiment, the telescopic device includes a first hinge plate 305, a second hinge plate 306, a roller 307, and a cylinder 308.

[0071] Specifically, one end of hinge plate 305 is hinged to the bottom of the fixed frame 301, and the other end is rotatably equipped with a roller 307, which rolls on the upper part of the docking frame 303. One end of hinge plate 306 is hinged to the top of the fixed frame 301, and the other end is also equipped with a roller 307, which rolls on the lower part of the docking frame 303. The two hinge plates are hinged together in the middle, and the two hinge plates are respectively hinged to the two ends of the cylinder 308. When the cylinder 308 works to extend or retract, the two hinge plates are pushed by the thrust and swing along the hinge point in the middle. Thus, through the swing of the two hinge plates, the docking frame 303 is displaced relative to the fixed frame 301, realizing the extension and retraction of the telescopic cover 302 on the two frames.

[0072] When the two hinge plates swing, the rollers 307 on the hinge plates will roll and displace, offsetting the vertical offset when the hinge plates swing, so that the docking frame 303 only makes lateral displacement.

[0073] It is worth noting that the telescopic cover 302 is designed with an accordion-style structure. The accordion-style cover forms an elastic telescopic structure with its own elastic potential energy, allowing for elastic expansion, contraction, and bending. Each fold of the cover is also fixed with a steel ring to improve the stability of the tubular structure of the telescopic cover 302. Therefore, it can expand the space of the telescopic chamber 3 during the entire telescopic docking process; provide a deformable chamber space for the transfer chamber 2 to swing with the angle adjustment device 5, so that the internal space of the chamber is not easily exposed to the external environment during the entire docking process; and provide elastic buffer for the docking end after docking, reducing wear at the docking position.

[0074] At the bottom of the telescopic chamber 3, a foot pedal 309 is also provided. The foot pedal 309 is fixedly installed at the bottom of the fixed frame 301 to provide a foot pedal 309 for personnel to pass through the telescopic chamber 3 after telescopic movement, so as to prevent personnel from directly stepping on the telescopic cover 302.

[0075] Example 4

[0076] To achieve rapid docking of the two modular container units, please refer to... Figures 6-10 In this embodiment, the snap-fit ​​device 8 includes a cantilever 801, a motor 802, a snap-fit ​​cavity plate 803, a stop block 804, and a straight arm buckle 805.

[0077] Specifically, at the docking ends of the two opposing modular units 7, a cantilever 801 is installed on the docking frame 303 of one docking end, and a snap-fit ​​cavity plate 803 is installed on the docking frame 303 of the other docking end. The snap-fit ​​cavity plate 803 has a docking cavity inside. During the docking process, the two docking frames 303 abut together, and the cantilever 801 is inserted into the docking cavity of the snap-fit ​​cavity plate 803, and the two are snap-fitted and matched.

[0078] In order to enable the cantilever 801 and the snap-fit ​​cavity plate 803 to be quickly disengaged, the cantilever 801 is rotatably mounted on the docking frame 303. The docking frame 303 is fixed with a second motor 802. The drive shaft of the second motor 802 is coaxially fixedly connected to one end of the cantilever 801. The other end of the cantilever 801 is provided with a straight arm buckle 805, and the buckle block of the straight arm buckle 805 is located in its vertical position. Inside the docking cavity of the snap-fit ​​cavity plate 803, a stop block 804 is vertically fixedly provided.

[0079] Among them, the straight arm buckle 805 is a flexible plate structure. When the cantilever 801 is connected to the snap-fit ​​cavity plate 803, the straight arm buckle 805 is inserted into the connection cavity. The snap block of the straight arm buckle 805 is blocked by the vertical position stop 804 and is squeezed to undergo elastic bending deformation, thus entering the connection cavity. After the snap block passes through the stop 804, the straight arm buckle 805 will elastically return to its original position. The straight arm buckle 805 then snaps onto the stop 804 in the connection cavity by snapping the snap block, thus locking the entire straight arm buckle 805 in the connection cavity and achieving connection fixation.

[0080] When docking and disengaging, motor 802 will drive the cantilever 801 to rotate 90 degrees, so that the locking blocks in the vertical position of the straight arm buckle 805 are distributed horizontally, so that they are no longer interlocked with the vertically set stop 804 in the docking cavity. By driving the docking frame 303 to retract through the telescopic device, the straight arm buckle 805 can be disengaged from the docking cavity, realizing rapid docking and disengagement.

[0081] 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.
