Description

Technical Field

[0001] This utility model relates to the field of modular cabin technology, specifically a wing-type modular cabin. Background Technology

[0002] Wing-type modular shelters are a type of specialized equipment in the field of modular shelter technology that has the function of space expansion. They are usually vehicle-mounted structures. When in use, the internal usable space can be quickly expanded by unfolding the top plate, bottom plate and various wall panels. They are widely applicable to scenarios such as vehicle transportation, field operations and temporary support, and meet diverse usage needs with their flexible space adjustment capabilities.

[0003] In practical applications, the mainstream casement windows used in wing-type modular shelters require a significant amount of external space when opened. When the shelter is densely packed or near walls or corners, the window sash is prone to collisions with surrounding objects, hindering opening and closing. Sliding windows offer poor protection. Casement windows, due to their opening and closing mechanism, are often blocked by the shelter walls after folding. Sliding windows, on the other hand, are more inconvenient to use if users forget to lock them (e.g., with bar locks, hook locks, crescent locks, handle locks, etc.). During transportation, they may slide and collide due to bumps or other external forces, causing damage. This makes them more troublesome to use, requiring staff to carefully check that the sliding windows are locked before each fold. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a wing-shaped container to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wing-shaped modular container, comprising a main body of the container, a ventilation assembly on the back of the main body, and the ventilation assembly comprising a support frame, a guide frame, a drip edge and a wall shell, a servo motor and a limit switch respectively installed inside the wall shell, and a lead screw connected to the output end of the servo motor, an electromagnetic brake installed between the lead screw and the wall shell, a window sash connected to the outside of the lead screw, and rollers and push plates connected to both sides of the bottom of the window sash, and sealing strips affixed to the sides and surface of the window sash.

[0006] By adopting the above technical solutions, a servo motor can drive the lead screw to rotate, thereby enabling the window sash to open and close electrically, reducing the inconvenience of manual operation and the space occupied when opening casement windows; the electromagnetic brake can limit the lead screw when power is off, reducing the window sash from being accidentally moved due to bumps; rollers and push plates can assist the window sash in moving and remove impurities, reducing obstacles to opening and closing; and sealing strips can fill gaps, reducing water and air leakage. All components work together to improve the practicality and stability of the cabin window.

[0007] Furthermore, the longitudinal section of the window sash is shaped like the number "7", and the drip edge is located above the window sash and the guide frame.

[0008] By adopting the above technical solution, the 7-shaped upper extension section of the window sash longitudinal section can shield the screw rod, reducing the direct corrosion of the screw rod by external rainwater and dust, and extending the service life of the screw rod; the drip edge located above the window sash and guide frame can prevent rainwater and dust from accumulating on the top of both, reducing water accumulation and rust, and dust accumulation and jamming, thus reducing the probability of window sash opening and closing failure.

[0009] Furthermore, the rollers are rotatably connected to the support frame, and the window sash is slidably connected to the guide frame.

[0010] By adopting the above technical solutions, the rolling connection between the roller and the support frame can significantly reduce the frictional resistance when the window sash moves, and improve the smoothness of opening and closing; the sliding connection between the window sash and the guide frame allows the guide frame to support the surface of the window sash, and together with the auxiliary support of the support frame for the bottom of the window sash, the weight of the window sash is shared, reducing the load on the screw rod, and at the same time reducing the risk of the window sash tilting forward when moving laterally.

[0011] Furthermore, the push plate is located on the side of the roller, and there is a gap between the bottom of the push plate and the lower part of the support frame.

[0012] By adopting the above technical solution, when the push plate moves laterally with the window sash, it can push large debris such as gravel accumulated at the bottom of the support frame into the through hole at the bottom of the support frame for discharge, reducing the obstruction of the rollers by the debris; the gap between the push plate and the bottom of the support frame can prevent the push plate from contacting and wearing with the support frame and rollers, extending the service life of the push plate and rollers, and reducing the frequency of subsequent maintenance.

[0013] Furthermore, the window sash is threadedly connected to a lead screw, and the window sash is slidably connected to the embedded wall shell.

[0014] By adopting the above technical solutions, the threaded connection between the window sash and the lead screw enables the lead screw to precisely drive the window sash to achieve lateral displacement when it rotates, providing a structural basis for electric opening and closing; the sliding connection between the window sash and the embedded wall shell can limit the movement trajectory of the window sash, ensuring that the window sash remains stable during the opening and closing process and avoiding problems such as deviation and jamming.

[0015] Furthermore, the window sash abuts against the limit switch.

[0016] By adopting the above technical solution, when the window sash is closed to a near-sealed position, the window sash abuts against the limit switch, and the limit switch can link the servo motor to stop running, accurately determining the closed position of the window sash. This effectively reduces situations such as the window sash not closing properly or not sealing tightly due to insufficient control precision of the servo motor, thus ensuring the sealing effect of the window.

[0017] Furthermore, a hatch is hinged to the outer surface of the main body of the container, a top plate is hinged to the upper sides of both sides of the main body of the container, a bottom plate is hinged to the lower sides of both sides of the main body of the container, and a second wall plate is hinged to the outer surface and back of both bottom plates, and a first wall plate is hinged to one side of both bottom plates.

[0018] By adopting the above technical solutions, the hinged structure allows the top plate, bottom plate, first wall panel, and second wall panel to be flexibly unfolded or folded: when space needs to be expanded, unfolding each component can create a larger internal usable space, suitable for field operations, temporary support, and other scenarios; when expansion is not required, folding each component can reduce the overall volume of the container, facilitating vehicle transportation or compact storage; the hatch can meet the needs of personnel and goods entering and exiting, ensuring the basic usability of the container.

[0019] Furthermore, four ventilation components are provided on one side of each of the two first wall panels.

[0020] By adopting the above technical solution, each of the two first wall panels is equipped with four ventilation components, which, together with one ventilation component on the back of the main body of the container, provide a total of five ventilation components. These components can simultaneously achieve ventilation and lighting from different areas of the container, greatly improving the air circulation efficiency and light brightness inside the container. This avoids the problem of insufficient local ventilation and lighting caused by a single ventilation component, and better meets the usage needs of multiple people or multiple devices inside the container.

[0021] Furthermore, five of the five ventilation components are detachably connected to the back of the main body of the container and one side of the two first wall panels by bolts, and the surface of the detachable wall shell is connected to a cover plate by bolts.

[0022] By adopting the above technical solution, the bolted detachable structure allows the buried wall shell to be easily removed from the main body of the container or the first wall panel, which facilitates the subsequent maintenance of the servo motor, lead screw and other electric drive structures inside the buried wall shell; the cover plate on the surface of the buried wall shell can also be removed by bolts, which can not only protect the internal components and reduce external corrosion, but also be quickly opened during maintenance, reducing the difficulty of operation.

[0023] Furthermore, the sealing strip is made of EPDM rubber.

[0024] By adopting the above technical solutions, EPDM rubber has good weather resistance and can adapt to temperature changes and rain erosion in complex environments such as the outdoors and vehicles. This reduces the aging and cracking of the sealing strip after long-term use, ensuring that the sealing strip always maintains good elasticity and sealing performance, and maintains the filling effect on the window sash gaps for a long time, reducing the occurrence of water and air leakage.

[0025] In summary, the present invention has the following main advantages: 1. This utility model, through the design of a servo motor, lead screw, sealing strip, limit switch, and electromagnetic brake, achieves two main benefits. First, the servo motor drives the lead screw to rotate, enabling the window sash to slide open and close without manual operation. This avoids the problem of casement windows occupying too much external space when open, reducing collisions and conflicts between windows in densely populated areas or near wall corners. Second, the limit switch engages with the window sash when closed, precisely determining the closing position in conjunction with the servo motor. Combined with the sealing strip made of EPDM rubber, it effectively fills gaps between window sashes and between the window sash and the wall, reducing water and air leaks. Simultaneously, the electromagnetic brake, as a normally closed brake, automatically limits the lead screw in power-off scenarios such as vehicle operation, reducing the possibility of the lead screw rotating due to bumps and the window sash opening and closing arbitrarily, improving stability in vehicle-mounted environments and increasing the convenience of window use. 2. This utility model, through the arrangement of a window sash, support frame, guide frame, and drip edge, features a window sash with a 7-shaped longitudinal section. The upper side extension can shield the lead screw, preventing it from being directly exposed and reducing the impact of external rainwater and dust on the lead screw, thus extending its service life. The support frame can cooperate with rollers to assist in supporting the window sash, and the guide frame provides support to the surface of the window sash, reducing the risk of the window sash tipping forward during lateral movement and distributing the weight of the window sash, thus reducing the load on the lead screw. The drip edge located above the window sash and guide frame can protect the tops of both, greatly reducing water and dust accumulation on the top and reducing wear between the window sash, guide frame, and wall panel, thereby increasing the service life of the structure. 3. This utility model, through the arrangement of rollers and push plates, forms a rolling connection between the rollers and the support frame, which reduces the frictional resistance when the window sash moves and improves the smoothness of opening and closing the window sash. The push plate is located on the side of the rollers and has a gap between its bottom and the lower part of the support frame, so it will not come into contact with the support frame and rollers and will not wear. At the same time, it can move synchronously with the lateral movement of the window sash, which can push large debris such as gravel from the lower part of the support frame into the through hole at the bottom of the support frame for discharge, reducing the obstruction of the rollers by debris and reducing the probability of the rollers getting stuck. This reduces the frequency of subsequent maintenance and ensures the smooth operation of the window sash for a long time. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1: A type of wing-shaped modular container, such as Figures 2-10As shown, the container includes a main body 1. A ventilation assembly is installed at the back of the main body 1. The ventilation assembly includes a support frame 7, a guide frame 8, a drip edge 10, and a wall shell 13. A servo motor 15 and a limit switch 17 are installed inside the wall shell 13. The output end of the servo motor 15 is connected to a lead screw 16. An electromagnetic brake 18 is installed between the lead screw 16 and the wall shell 13. A window sash 9 is connected to the outside of the lead screw 16 and is threadedly connected to the lead screw 16. The longitudinal section of the window sash 9 is shaped like the number "7". The window sash 9 is slidably connected to the guide frame 8 and the embedded wall shell 13. The window sash 9 abuts against the limit switch 17. The drip edge 10 is located above the window sash 9 and the guide frame 8. Rollers 11 and push plates 12 are connected to both sides of the bottom of the window sash 9. The rollers 11 are rotatably connected to the support frame 7. The push plates 12 are located on the side of the rollers 11. There is a gap between the bottom of the push plates 12 and the lower part of the support frame 7. When it is necessary to open or close the window sash 9, the servo motor 15 in the embedded wall shell 13 is activated and connected to the circuit in the cabin through a cable. Staff can control the servo motor 15 to open and close via a control cabinet or switch inside the shelter. After the servo motor 15 starts, its output drives the lead screw 16 to rotate. Since the window sash 9 is threadedly connected to the lead screw 16, and the window sash 9 is slidably engaged with the embedded wall shell 13 and the guide frame 8, the rotation of the lead screw 16 will drive the window sash 9 to move laterally along the guide frame 8, thus realizing the electric opening and closing of the window sash 9. During this process, the rollers 11 on both sides of the bottom of the window sash 9 are tumbling connected to the support frame 7. The support frame 7 provides auxiliary support to the bottom of the window sash 9, while the guide frame 8 provides support to the surface of the window sash 9. The two together share the weight of the window sash 9, reducing the load on the lead screw 16 and reducing the risk of the window sash 9 tilting forward during lateral movement. In addition, the longitudinal section of the window sash 9 is shaped like the number 7, and its upper side extension can shield the lead screw 16, reducing the direct corrosion of the lead screw 16 by external rainwater and dust. Sealing strips 14 are pasted on the sides and surface of the window sash 9, which can fill the gaps between the two window sashes 9 and between the window sash 9 and the wall, reducing water and air leakage.

[0031] See Figure 1 and Figure 2 In the above embodiment, a hatch 2 is hinged to the outer surface of the main body 1 of the container. Top plates 3 are hinged to the upper sides of both sides of the main body 1, and bottom plates 4 are hinged to the lower sides of both sides of the main body 1. Second wall plates 6 are hinged to the outer surface and back of the two bottom plates 4, and first wall plates 5 are hinged to one side of the two bottom plates 4. When the container needs to expand its internal space, it can operate through its hinged structure to unfold the two top plates 3 and bottom plates 4 outward in sequence. Some wing-type containers can automatically unfold the top plates 3 and bottom plates 4 through hydraulic, electric or pneumatic structures. Then, the staff unfolds the second wall plates 6 and then unfolds the first wall plates 5. The structure is then limited by the container's own limiting structure, so that the wall plates, top plates 3 and bottom plates 4 together form an expanded space after unfolding. When expansion is not needed, the operation is reversed, and the second wall plates 6, first wall plates 5, bottom plates 4 and top plates 3 are successively folded back to the sides of the main body 1 of the container to complete the space shrinkage, which is suitable for vehicle transportation or compact storage needs.

[0032] Example 2: Based on the above embodiment one, the following settings are now implemented to increase lighting and ventilation and facilitate maintenance.

[0033] See Figure 2 , Figure 3 , Figure 4 and Figure 10 In the above embodiment, four ventilation components are respectively provided on one side of the two first wall panels 5. Five of the five ventilation components are embedded in the wall shells 13 and are respectively detachably connected to the back of the main body 1 of the cabin and one side of the two first wall panels 5 by bolts. The surface of the embedded wall shell 13 is detachably connected to the cover plate by bolts. As the ventilation component that is the core of the cabin's ventilation and lighting, its embedded wall shell 13 is fixed to the back of the main body 1 of the cabin and one side of the two first wall panels 5 by bolts. The cover plate on the surface of the embedded wall shell 13 is also detachably connected by bolts. When inspecting the electric drive structure, the staff only needs to unscrew the bolts to disassemble the window sash 9 and then remove the cover plate. At this time, the servo motor 15, lead screw 16 and other components can be inspected. If the entire electric drive component needs to be replaced, the bolts between the embedded wall shell 13 and the wall panel are unscrewed to disassemble the embedded wall shell 13. The five ventilation components on the back and two sides of the cabin work together to further improve the overall lighting and ventilation efficiency of the cabin.

[0034] Example 3: Based on the above embodiment one, the following settings are now adopted to adapt to the outdoor environment.

[0035] See Figure 4 , Figure 7 , Figure 8 and Figure 9 In the above embodiments, the sealing strip 14 is made of EPDM rubber, which has good weather resistance and is not prone to aging due to environmental factors during long-term use.

[0036] The implementation principle of this utility model is as follows: First, when the internal space of the container needs to be expanded, the two top plates 3 and the bottom plate 4 can be unfolded outward in sequence through its hinged structure. Some wing-type container can automatically unfold the top plate 3 and the bottom plate 4 through hydraulic, electric or pneumatic structures. Then, the staff unfolds the second wall plate 6 and then the first wall plate 5. The structure is then limited by the container's own limiting structure, so that the wall plates, top plate 3 and bottom plate 4 together form an expanded space after unfolding. When expansion is not needed, the operation is reversed, and the second wall plate 6, the first wall plate 5, the bottom plate 4 and the top plate 3 are successively folded back to both sides of the container body 1 to complete the space shrinkage, which is suitable for vehicle transportation or compact storage needs. Next, the ventilation component, which is the core of ventilation and lighting in the cabin, has its embedded wall shell 13 fixed to the back of the cabin body 1 and one side of the two first wall panels 5 by bolts. The cover plate on the surface of the embedded wall shell 13 is also connected and disassembled by bolts. When inspecting the electric drive structure, the staff only needs to unscrew the bolts to disassemble the window sash 9 and then remove the cover plate. At this time, the servo motor 15, lead screw 16 and other components can be inspected. If the entire electric drive component needs to be replaced, the bolts between the embedded wall shell 13 and the wall panel are unscrewed to disassemble the embedded wall shell 13. The five ventilation components on the back and sides of the cabin work together to further improve the overall lighting and ventilation efficiency of the cabin. When the window sash 9 needs to be opened or closed, the servo motor 15 inside the embedded wall shell 13 is activated and connected to the circuit inside the cabin via a cable. The staff can control the servo motor 15 to open or close from the control cabinet or switch inside the cabin. After the servo motor 15 is started, the output end drives the lead screw 16 to rotate. Since the window sash 9 is threadedly connected to the lead screw 16, and the window sash 9 is slidably engaged with the embedded wall shell 13 and the guide frame 8, the rotation of the lead screw 16 will drive the window sash 9 to move laterally along the guide frame 8, realizing the electric opening and closing of the window sash 9. During this process, the rollers 11 on both sides of the bottom of the window sash 9 are tumbling connected to the support frame 7. The support frame 7 provides auxiliary support to the bottom of the window sash 9, while the guide frame 8 provides support to the surface of the window sash 9. The two together share the weight of the window sash 9, reducing the load on the lead screw 16 and reducing the risk of the window sash 9 tilting forward when moving laterally. In addition, the longitudinal section of the window sash 9 is shaped like the number 7, and its upper side extension can shield the lead screw 16, reducing the direct corrosion of the lead screw 16 by external rainwater and dust. Meanwhile, the push plate 12, which moves horizontally in sync with the window sash 9, is located on the side of the roller 11. There is a gap between the bottom of the push plate 12 and the lower part of the support frame 7, so that it will not come into contact with or wear against the support frame 7 or the roller 11. During movement, the push plate 12 can push large debris such as gravel accumulated in the lower part of the support frame 7 into the through hole at the bottom of the support frame 7. The debris is discharged through the through hole, reducing the obstruction of the roller 11 to the rolling of the debris and ensuring that the window sash 9 opens and closes smoothly. The drip edge 10 located above the window sash 9 and the guide frame 8 can prevent rainwater and dust from falling to the top of the two, reducing water and dust accumulation on the top, reducing the probability of parts being corroded by water accumulation or stuck by dust accumulation, and extending the service life. When the window sash 9 is closed to a near-sealed position, it will abut against the limit switch 17. After receiving the contact signal, the limit switch 17 will stop the servo motor 15 through the control cabinet of the cabin circuit, accurately positioning the closed position of the window sash 9 and avoiding incomplete sealing due to insufficient closing accuracy. At this time, the sealing strip 14 pasted on the side and surface of the window sash 9 is made of EPDM rubber material. This material has good weather resistance and is not easy to age due to environmental factors after long-term use. It can fill the gaps between the two window sashes 9 and between the window sash 9 and the wall, reducing water and air leakage. In the event of a power outage, such as when the vehicle is in motion, the electromagnetic brake 18 in the wall shell 13, as a normally closed brake, will automatically limit the screw 16 to prevent the screw 16 from rotating due to vehicle bumps, thereby preventing the window sash 9 from opening and closing arbitrarily and ensuring the structural stability during the driving process.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
