Description

Technical Field

[0001] This invention belongs to the field of modular cabin equipment technology, specifically relating to a side-wall translational modular cabin body expansion mechanism. Background Technology

[0002] The aforementioned modular shelter refers to a convenient and mobile unit formed by organically combining various sturdy materials. This shelter can accommodate different equipment and devices according to varying usage requirements. Modular shelters are important equipment commonly used in military, medical, and communications fields, and are applied in situations such as mobile command systems, communications, medical emergency response, and logistical support. Furthermore, modular shelters are also used in civilian special vehicles, such as emergency communication vehicles, power station vehicles, and large equipment loading vehicles. The modular shelter expansion structure is a commonly used structural device on the modular shelter body to expand its internal volume. Currently, military and civilian expandable modular shelters generally adopt a drawer-type expansion structure, that is, an integral telescopic expansion compartment is set within the modular shelter body, and the expansion is propelled outward using electric, hydraulic, or other drive methods. Chinese patent document CN217374697U discloses a multifunctional expandable cabin, including a fixed cabin, a telescopic cabin, a folding floor, and a telescopic cabin transmission mechanism. When the telescopic cabin is deployed, it is located on one side of the fixed cabin, and the folding floor is unfolded and laid flat at the bottom of both the fixed and telescopic cabins. When the telescopic cabin is retracted, it is stored inside the fixed cabin, and several movable floor panels fold upwards and stand upright inside the telescopic cabin. This invention has a simple and compact structure and low cost. When the vehicle is in motion, the telescopic cabin is retracted into the cabin body or container under the drive of the transmission mechanism. When the vehicle is parked, the transmission mechanism can push the telescopic cabin outwards from the cabin body or container to expand the working area, making operation very convenient and flexible. However, since the width of traditional modular containers is the same as that of standard shipping containers, the usable space inside the container is quite small. Existing technologies and the telescopic extension modules in the aforementioned patent documents are set inside the modular container, but the width of the modular container is strictly limited by the width of the transport vehicle. Therefore, the telescopic extension module will greatly encroach on the usable space inside the modular container, resulting in weak functionality inside the modular container. In addition, the manufacturing and maintenance costs of this type of integrated telescopic module structure are high, the electric and hydraulic drive methods used are also more complex, and the stability and reliability of the deployment and retrieval work are also poor.

[0003] Therefore, it is necessary to design a structurally sound modular container expansion mechanism that achieves a perfect balance between rapid and convenient expansion and maximizing space, thereby ensuring its own operational stability and reliability while also meeting the various activity requirements inside the modular container. To this end, the applicant has developed a beneficial design, and the technical solution described below arose from this context. Summary of the Invention

[0004] The purpose of this invention is to provide a side-mounted telescopic cabin expansion mechanism that is compact in structure, efficient and quick to use, and helps to eliminate the need for an integral telescopic cabin expansion structure. Instead, it connects a retractable flap component and a hinged folding assembly on one side of the cabin body, thereby effectively reducing the space occupied by the expansion structure in the main cabin when the cabin body is folded up. This further meets various activity requirements and enhances the functionality of the cabin.

[0005] The objective of this invention is achieved as follows: a side-mounted sliding container expansion mechanism includes a frame, an upper flap, a lower flap, side panels, and a pair of side end plate assemblies. The frame includes a pair of longitudinal frame beams forming its left and right sides, a top end transverse frame beam forming its upper part, and a bottom end transverse frame beam forming its lower part. The upper flap is pivotally connected to the top end transverse frame beam, while the lower flap is pivotally connected to the bottom end transverse frame beam and positioned below the upper flap. Both the upper and lower flaps can be retracted to a vertical state or extended outward to a horizontal state. The side panels are vertically oriented, and the two side end plate assemblies are respectively hinged to the left and right ends of the side panels and positioned between the side panels and the frame. Each side end plate assembly includes at least two movable end plates hinged together by hinges, close to... The movable end plates of the side panel are hinged to the lateral edges of the side panel, while the movable end plates closer to the frame are hinged to their corresponding longitudinal frame beams. The side panel sliding container expansion mechanism has a retracted state and an extended state. In the retracted state, the upper and lower flaps retract to a vertical state, and the side panel is retracted into the space between the upper and lower flaps and the frame. The multiple movable end plates of the side panel assembly converge and remain parallel to the side panel. In the extended state, the upper and lower flaps flip to a horizontal state, and the side panel can slide on the lower flap in the horizontal state and move away from the frame in the horizontal direction. The multiple movable end plates of the side panel assembly extend, and when the side panel slides to a predetermined position, the multiple movable end plates can maintain a predetermined vertical angle with the side panel.

The roller positioning frame is hollow inside and has a downward opening. Multiple support rollers are pivotally connected to the roller positioning frame and extend downward out of their openings. On the side surface of the lower flap facing the side panel and at positions corresponding to the multiple sets of support roller assemblies, multiple lower flap limiting slide rails are formed. In the unfolded state, the lower flap is flipped to a horizontal state, and the support rollers of the multiple sets of support roller assemblies can slide outward in their respective lower flap limiting slide rails.

[0007] In another specific embodiment of the present invention, an upper flap hinge is connected to the upper long side of the upper flap, and the upper flap is pivotally connected to the top end cross frame beam through the upper flap hinge; while a lower flap hinge is connected to the lower long side of the lower flap, and the lower flap is pivotally connected to the bottom end cross frame beam through the lower flap hinge.

[0008] In another specific embodiment of the present invention, an upper power cylinder is respectively provided at the left and right ends of the upper flap. The two upper power cylinders are connected between the upper flap body and the frame body, and the upper power cylinder includes an upper power cylinder body and an upper power cylinder piston rod passing through the upper power cylinder body. The upper power cylinder piston rod can reciprocate within the upper power cylinder body. A longitudinal frame beam connecting seat is fixedly installed on each of the two longitudinal frame beams at the position corresponding to the upper power cylinder. An upper flap connecting seat is fixedly installed on the upper flap at the position corresponding to the two side power cylinders. The tail end of the upper power cylinder body is pivotally connected to the longitudinal frame beam connecting seat, thereby realizing the hinge between the upper power cylinder body and the longitudinal frame beam. The end of the upper power cylinder piston rod away from the upper power cylinder body is also pivotally connected to the upper flap connecting seat, thereby realizing the hinge between the upper power cylinder piston rod and the upper flap body.

[0009] In another specific embodiment of the present invention, a lower power cylinder is respectively provided at the left and right ends of the lower flap. The two lower power cylinders are connected between the lower flap body and the frame body, and the lower power cylinder includes a lower power cylinder body and a lower power cylinder piston rod passing through the lower power cylinder body. The lower power cylinder piston rod can reciprocate within the lower power cylinder body. A longitudinal frame beam lower connecting seat is fixedly installed on each of the two longitudinal frame beams at the positions corresponding to the lower power cylinders on both sides. A lower flap connecting seat is fixedly installed on the lower flap at the positions corresponding to the lower power cylinders on both sides. The tail end of the lower power cylinder body is pivotally connected to the longitudinal frame beam lower connecting seat, thereby realizing the hinge between the lower power cylinder body and the longitudinal frame beam. The end of the lower power cylinder piston rod away from the lower power cylinder body is also pivotally connected to the lower flap connecting seat, thereby realizing the hinge between the lower power cylinder piston rod and the lower flap body.

[0010] In another specific embodiment of the present invention, a side panel hinge is installed at the left and right edges of the side panel, and the movable end plate of the side panel end plate assembly that is close to the side panel is hinged to the side panel through the side panel hinge.

[0012] In a more specific embodiment of the present invention, a plurality of side panel working windows are provided on the side panel.

[0013] The technical advantages of the present invention are as follows: The side-wall sliding container expansion mechanism of the present invention can conveniently and quickly expand the container in the length direction. This telescopic structure can be arranged in parallel at one or more ends of the container in the length direction, and the upper and lower flaps respectively form the top and bottom panels of the expansion space. The side panels and the side end panels on both sides together form the side panels and front and rear panels of the expansion space, thereby realizing the construction of a closed expansion space. This eliminates the need for an integral telescopic cabin expansion structure, resulting in a simple and compact overall structure that can quickly and conveniently expand the internal space of the container, meeting the requirements of... To meet various activity needs and enhance the functionality of the modular cabin, and in situations where the cabin needs to be retracted, such as during transport, the entire cabin can be easily and conveniently folded up so that its length or width meets the standard dimensions required by transport vehicles and other work operations, ensuring safety during work and transportation, and making it suitable for a variety of different usage scenarios; on the other hand, the push-plate type side panels and hinged plate structure side panel components can significantly reduce the space occupied by the cabin's internal space compared to the overall telescopic extended cabin in the existing technology, meeting various usage needs inside the cabin, improving the comfort inside the cabin while effectively reducing the difficulty of assembly and installation.

However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of the present invention should be considered within the scope of protection of the present invention.

[0020] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the position of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be construed as a special limitation on the technical solution provided by this invention.

[0021] Please see Figures 1 to 3 This invention relates to a side-panel sliding container expansion mechanism, comprising a frame 1, an upper flap 2, a lower flap 3, side panels 4, and a pair of side end panel assemblies 5; wherein the frame 1 is a rectangular frame connected to the main container body, and can be connected to the main container body in parallel, one or more in number, and has a pair of longitudinal frame beams 11 forming on its left and right sides, a top end transverse frame beam 12 forming on its upper part, and a bottom end transverse frame beam 13 forming on its lower part; the upper flap 2 is pivotally connected to the top end transverse frame beam 12, and the lower flap 3 is pivotally connected to and positioned on the bottom end transverse frame beam 13. The upper flap 2 and the lower flap 3 are both located below the aforementioned upper flap 2 and can be folded up to a vertical state or unfolded outward to a horizontal state. The aforementioned side panel 4 is vertically arranged, and the two aforementioned side panel end plate assemblies 5 are respectively hinged to the left and right ends of the side panel 4 and positioned between the aforementioned side panel 4 and the frame body 1. The side panel end plate assembly 5 includes at least two movable end plates 51 that are hinged together by hinges. The movable end plate 51 close to the aforementioned side panel 4 is hinged to the lateral edge of the aforementioned side panel 4, and the movable end plate 51 close to the aforementioned frame body 1 is hinged to its corresponding longitudinal frame beam 11.

[0022] In this embodiment, the aforementioned side-wall sliding container expansion mechanism has a retracted state and an extended state. In the retracted state, the aforementioned upper flap 2 and lower flap 3 retract to a vertical state, and the aforementioned side panel 4 retracts into the space between the upper flap 2, lower flap 3, and frame 1. The multiple movable end plates 51 of the aforementioned side panel assembly 5 converge and remain parallel to the side panel 4. In the extended state, the aforementioned upper flap 2 and lower flap 3 flip to a horizontal state, and the aforementioned side panel 4 can slide on the lower flap 3 in the horizontal state and move horizontally. Away from the frame 1, the multiple movable end plates 51 of the aforementioned side panel assembly 5 extend and expand the width of the cabin. When the side panel 4 slides to a predetermined position, the multiple movable end plates 51 can maintain a predetermined vertical angle with the side panel 4. At this time, the upper flip plate 2 constitutes the top panel of the expanded space, and the lower flip plate 3 constitutes the bottom panel of the expanded space. The moved side panel 4 and the side short plate assemblies 5 on both sides together constitute the side panel and front and rear panel of the expanded space, realizing the final expansion of the expansion mechanism and completing the increase and expansion of the cabin space.

[0023] Furthermore, multiple sets of horizontally arranged support roller assemblies 41 are fixedly installed at the bottom of the side surface of the aforementioned side panel 4 opposite to the aforementioned frame body 1.

The roller positioning frame 411 is hollow inside and has a downward-facing opening. The multiple aforementioned support rollers 412 are pivotally connected to the aforementioned roller positioning frame 411 and extend downward out of its opening. On the inner surface of the aforementioned lower flap 3 facing the aforementioned side panel 4, and at the position corresponding to the multiple sets of support roller assemblies 41, multiple lower flap limiting slide rails 31 are formed. In the aforementioned unfolded state, as Figure 2 and Figure 3 As shown, when the aforementioned lower flap 3 is flipped to a horizontal state, the support rollers 412 of the multiple sets of aforementioned support roller assemblies 41 can slide outward in their respective lower flap limiting slide rails 31, thereby expanding the width of the container and increasing the space of the container.

The aforementioned upper power cylinder piston rod 222 can slide back and forth in the upper power cylinder body 221. A longitudinal frame beam connecting seat 111 is fixedly installed on the two aforementioned longitudinal frame beams 11 at the positions corresponding to the upper power cylinders 22, and an upper flap connecting seat 23 is fixedly installed on the aforementioned upper flap 2 at the positions corresponding to the two side power cylinders 22. The tail end of the upper power cylinder body 221 is pivotally connected to the connecting seat 111 on the longitudinal frame beam, thereby realizing the hinge between the upper power cylinder body 221 and the longitudinal frame beam 11. The end of the upper power cylinder piston rod 222 away from the upper power cylinder body 221 is also pivotally connected to the upper flap connecting seat 23, thereby realizing the hinge between the upper power cylinder piston rod 222 and the upper flap 2 body. The upper power cylinder 22 is a hydraulic cylinder, pneumatic cylinder or electric cylinder and is connected to an external control system. When it is necessary to flip the upper flap 2 upward, the upper power cylinder piston rod 222 extends out, and the upper power cylinder body 221, which is hinged to the longitudinal frame beam 11, rotates upward, thereby driving the upper flap 2 to rotate.

[0026] Similarly, a lower power cylinder 33 is respectively provided at the left and right ends of the aforementioned lower flap 3. The two lower power cylinders 33 are connected between the lower flap 3 body and the frame body 1, and the lower power cylinder 33 includes a lower power cylinder body 331 and a lower power cylinder piston rod 332 passing through the lower power cylinder body 331. The aforementioned lower power cylinder piston rod 332 can slide back and forth in the lower power cylinder body 331. A longitudinal frame beam lower connecting seat 1 is fixedly installed on the two aforementioned longitudinal frame beams 11 at the positions corresponding to the lower power cylinders 33 on both sides. 12. A lower flap connecting seat 34 is fixedly installed on the aforementioned lower flap 3 at the position corresponding to the lower power cylinders 33 on both sides. The tail end of the aforementioned lower power cylinder body 331 is pivotally connected to the lower connecting seat 112 of the longitudinal frame beam, thereby realizing the hinge between the lower power cylinder body 331 and the longitudinal frame beam 11. The end of the aforementioned lower power cylinder piston rod 332 away from the aforementioned lower power cylinder body 331 is also pivotally connected to the lower flap connecting seat 34, thereby realizing the hinge between the lower power cylinder piston rod 332 and the lower flap 3 body.

[0027] Please see Figure 4 and combined Figure 1A side panel hinge 42 is installed at the left and right edges of the aforementioned side panel 4, and the movable end plate 51 of the aforementioned side panel end plate assembly 5, which is close to the aforementioned side panel 4, is hinged to the aforementioned side panel 4 through the side panel hinge 42.

[0028] Preferably, the longitudinal frame beam 11, the top end transverse frame beam 12, and the bottom end transverse frame beam 13 of the aforementioned frame body 1 are all tubular truss structures with triangular units.

[0029] Preferably, a plurality of side panel working windows 43 are provided on the aforementioned side panel 4. Figure 1 The diagram shows three windows. Ventilation can be achieved by opening the side panel working window 43, which also ensures a wide field of vision for the container and meets its usage needs in specific environments.

[0030] Please see Figures 1 to 3 The applicant briefly describes the working principle of the technical solution provided by this invention: When the side-mounted sliding modular cabin expansion mechanism is in the retracted state, i.e., stored at one side of the modular cabin, as... Figure 1 As shown, at this time, the side panel 4 is located close to the frame 1, while the upper flip panel 2 and lower flip panel 3 are retracted to a vertical state and located on the outside of the side panel 4. The multiple movable end plates 51 of the end plate assembly 5 are folded together and kept parallel to the side panel 4. In this retracted state, the side panel 4, upper flip panel 2, lower flip panel 3, and side end plate assembly 5 form a simple and compact folding structure. The components are tightly connected, and the footprint is small. When the device is parked and needs to be expanded, the upper flip panel 2 and lower flip panel 3 must first be flipped open. At this time, the operation control system causes the upper power cylinder 22 and lower power cylinder 33 to start working, respectively pushing the upper flip panel 2 and lower flip panel 3 to flip. Figure 2 As shown, the upper flip plate 2 rotates 90 degrees upwards to a preset position using the upper flip plate hinge 21 as the rotation axis and remains horizontal, while the lower flip plate 3 rotates 90 degrees downwards to a preset position using the lower flip plate hinge 32 as the rotation axis and remains horizontal. At this time, the upper flip plate 2 and the lower flip plate 3 respectively constitute the top and bottom panels of the extended space. Subsequently, the side panel 4 is pushed outwards, allowing it to slide on the horizontal lower flip plate 3 to achieve outward expansion. The support roller assembly 41 at the lower part of the side panel 4 can slide on the limiting slide rail 31 of the lower flip plate 3. When the support roller 412 slides to the far end of the limiting slide rail 31, the side panel 4 moves to the preset extension position. During this process, the multiple movable end plates 51 of the side panel end plate assembly 5, which is hinged to the side panel 4, extend. Figure 3As shown, at this time, the multiple movable end plates 51 of the two side panel assemblies 5 can maintain a preset vertical angle with the side panel 4 and form the front and rear end plates of the expansion space, ultimately realizing the extension of the expansion mechanism to meet the working needs inside the cabin; when it is necessary to retract the expansion mechanism, simply reverse the operation, push the side panel 4 inward and realize the inward rotation of the upper flip plate 2 and the lower flip plate 3, which is convenient for transportation and storage, and the operation is simple and quick.
