Description

Technical Field

[0001] This application relates to the field of vehicle-mounted structures, and in particular to a multi-purpose vehicle-mounted automated expansion cabin and its control method. Background Technology

[0002] A mobile shelter typically refers to a closed cabin structure used to provide temporary medical or other services. This cabin can be a building fixed to the ground or a mobile facility installed on a vehicle or other vehicle. Among them, vehicle-mounted mobile shelters are widely used in emergency situations such as natural disasters and sudden outbreaks of infectious diseases due to their portability and flexibility.

[0003] Vehicle-mounted modular shelters are a type of modular shelter that can be easily moved by vehicles, offering high flexibility. However, due to the limited carrying capacity of vehicles, the volume of a vehicle-mounted modular shelter cannot exceed that of the transport vehicle by much. Therefore, the size of the transport vehicle has a significant impact on the space size of the vehicle-mounted modular shelter. Summary of the Invention

[0004] To increase the space of the vehicle-mounted container, this application provides a multi-purpose vehicle-mounted automated expansion container.

[0005] The multi-purpose vehicle-mounted automated expandable cabin provided in this application adopts the following technical solution:

[0006] A multi-purpose vehicle-mounted automated expandable cabin includes a cabin body, which comprises a bottom plate, side plates, end plates, and a top plate. The bottom plate is detachably mounted on a vehicle body. Two side plates are fixedly mounted at both ends of the bottom plate in the width direction. Two end plates are fixedly mounted at both ends of the bottom plate in the length direction. The top plate is fixed at the end of the top plate and side plates away from the bottom plate. A cabin door is provided on the cabin body. The cabin body is characterized by having an expandable compartment that slides on it. The expandable compartment is detachably mounted on the cabin body. The expandable compartment has a vent, and a baffle is rotatably mounted on the vent.

[0007] By adopting the above technical solution, a sliding expansion module is set outside the main body of the cabin. The cabin space is expanded by sliding the expansion module. At the same time, the expansion module is detachable. By removing the expansion module from the main body of the cabin, it can be reinstalled on the ground to form another new expansion module, thereby realizing the expansion of the cabin space and increasing the cabin space without changing the transport vehicle.

[0008] Optionally, the expansion compartment is slidably mounted on the top of the main body. The expansion compartment includes a long plate, short plates, and a cover plate. Two long plates are slidably mounted on two side plates, and two short plates are slidably mounted on two end plates. The two ends of the long plate are detachably connected to the two short plates, and the two ends of the short plates are detachably connected to the two long plates. The cover plate is detachably fixed to the two long plates and the two short plates around its perimeter. A receiving platform is fixedly provided on both the side plates and the end plates. The long plate is mounted on the side plate and is flush with the surface of the receiving platform of the side plate. The short plate is mounted on the end plate and is flush with the surface of the receiving platform of the end plate.

[0009] Optionally, a guide rod is vertically arranged on the receiving platform. One end of the guide rod is detachably installed on the receiving platform, and the other end is inserted into a long plate or a short plate and slides within the long plate or the short plate. The guide rod includes a mounting part and a rotating part. The mounting part is detachably installed on the receiving platform, and the rotating part is hinged to the mounting part. A rotating bolt and a rotating nut are embedded between the mounting part and the rotating part. The rotating bolt passes through the mounting part and the rotating part. The rotating part is rotatably mounted on the mounting part with the rotating bolt as its axis of rotation. The rotating nut is threaded onto the rotating bolt. Tightening the rotating nut fixes the rotating part to the mounting part.

[0010] Optionally, a lifting rod is slidably provided on both the long plate and the short plate. One end of the lifting rod is inserted into the long plate or the short plate, and the other end is detachably connected to the cover plate. The lifting rod is slidably provided on the long plate or the short plate.

[0011] Optionally, a rotating shaft is fixed at one end of the lifting rod inserted into the long plate or the short plate, and a guide groove is opened on the short plate or the long plate corresponding to the rotating shaft. A rotation port is opened at the end of the guide groove away from the receiving platform.

[0012] Optionally, the side plate and the end plate are vertically provided with positioning grooves, and the long plate and the short plate are fixed with positioning blocks corresponding to the positioning grooves.

[0013] Optionally, there are two top plates, each with a width half that of the bottom plate, and the two top plates are hinged to the side plates respectively.

[0014] Optionally, a driving block is slidably disposed on the side plate. One end of the driving block extends into the positioning groove, and the other end abuts against the top plate. The positioning block slides, causing the driving block to slide. When the positioning block is at the top of the positioning groove, the positioning block drives the driving block to slide and drive the top plate to rotate until it is parallel to the side plate. The top plate is away from the side plate and abuts against the cover plate at one end.

[0015] Optionally, the expansion compartment is slidably inserted into the side plate, the side plate has an expansion hole, the expansion compartment is inserted into the expansion hole, and a side slide plate is slidably provided on the side plate. When the expansion compartment is removed from the compartment body, the side slide plate slides to close the expansion hole.

[0016] A control method for a multi-purpose vehicle-mounted automated expandable cabin includes: S1: cabin expansion; driving the expandable cabin to slide out of the cabin body to expand the cabin body; S2: cabin disassembly; driving the expandable cabin to slide away from the cabin body to disassemble the cabin, and placing the disassembled expandable cabin separately to form a new cabin; S3: cabin storage; installing the disassembled expandable cabin back into the cabin body and storing the expandable cabin back into the cabin body to store the cabin.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. An extendable module is installed on the outer shell of the main body of the container to expand the space of the container. The extendable module is detachable and can be removed from the main body of the container and reinstalled on the ground to form another new extendable module, thereby expanding the space of the vehicle-mounted container and increasing the space of the vehicle-mounted container without changing the transport vehicle.

[0019] 2. The installation of the receiving platform can make the surface of the container on the vehicle flat after the expansion compartment is installed, reducing the probability of transportation accidents caused by protrusions on the vehicle surface.

[0020] 3. Remove the cover plate, slide the long plate and short plate to a position higher than the hinge point of the mounting part and the rotating part, loosen the rotating nut to allow the rotating part to rotate, and drive the rotating part to rotate the long plate or short plate, so that the long plate or short plate can act as a temporary canopy;

[0021] 4. The sliding mechanism of the lifting rod can raise the cover plate, further expanding the space of the container. The rotating mechanism of the lifting rod can support the long or short board by rotating the lifting rod when the long or short board is used as a canopy, so that one end of the lifting rod extends out of the long or short board and abuts against the main body of the container.

[0022] 5. Due to the detachable design of the expansion compartment, the main body of the compartment needs to have its own top plate to ensure that the main body can become a sealed container independently after the expansion compartment is removed. However, the presence of the top plate will affect the expansion of the container when it is being expanded. By using a drive block in conjunction with a positioning block, the top plate is driven to rotate and connect the main body of the compartment and the expansion compartment while the expansion compartment is sliding and expanding. This reduces the impact of the top plate on the expansion of the main body of the compartment, and at the same time, the top plate can also serve as a support for the cover plate, thereby improving the structural strength of the expansion compartment.

Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Example 1

[0041] This application discloses a multi-purpose vehicle-mounted automated expandable cabin, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 12The system includes a cabin body 1, which comprises a floor plate 101 detachably mounted to the vehicle body by bolts, two side plates 102 respectively fixed at both ends of the floor plate 101 in the width direction, two end plates 103 respectively fixed at both ends of the floor plate 101 in the length direction, and a top plate 104 fixed at the end of the end plates 103 and side plates 102 away from the floor plate 101. The floor plate 101, side plates 102, end plates 103 and top plate 104 are welded together to form a hollow cabin body that is a cuboid in shape. A cabin door 2 is provided on the cabin body 1. In this embodiment, the cabin door 2 is provided on one of the side plates 101. On 02, the hatch 2 opens to connect the inside and outside of the main body 1. An extension compartment 3 is slidably mounted on the main body 1. The extension compartment 3 is slidably mounted on the main body 1 along its height direction. The extension compartment 3 is detachably mounted on the main body 1. The extension compartment 3 includes two long plates 301 that are slidably mounted on two side plates 102, two short plates 302 that are slidably mounted on two end plates 103, and cover plates 303 that are detachably fixed to the two long plates 301 and the two short plates 302 on all four sides. The two ends of the long plates 301 are detachably connected to the two short plates 302 along their length. The short plate 302 is detachably connected to two long plates 301 at both ends along its length. The long plates 301, short plates 302, and cover plate 303 form a bottomless hollow cuboid chamber. In this embodiment, both ends of the long plates 301 and short plates 302 are provided with slots and fixed with inserts. The slots and inserts between adjacent long plates 301 and short plates 302 are compatible, and the assembly between the long plates 301 and short plates 302 is achieved through the cooperation of the slots and inserts. The expansion compartment 3 is provided with a vent 15, and a baffle 16 is rotatably installed on the vent 15. By rotating the baffle 16... 6. Ventilation is achieved by opening the vent 15. When the expansion compartment 3 is removed and used separately, the vent 15 can serve as the entrance and exit of the expansion compartment 3. In this embodiment, the vent 15 is set on one of the long plates 301. A sliding expansion compartment 3 is installed on the outer casing of the main body 1. The space of the container is expanded by sliding the expansion compartment 3. At the same time, the expansion compartment 3 is detachable. After the expansion compartment 3 is removed from the main body 1, it can be reinstalled on the ground to form another new expansion compartment 3, thereby realizing the expansion of the space of the vehicle-mounted container and increasing the space of the vehicle-mounted container without changing the transport vehicle.

[0042] Reference Figure 1 and Figure 2Both the side plate 102 and the end plate 103 are fixed with a receiving platform 4. In this embodiment, the receiving platform 4 is a cuboid ring structure that is sleeved and fixed outside the cabin body 1. The cabin door 2 is opened in the area where the receiving platform 4 is fixed in the cabin body 1. The long plate 301 is sleeved on the side plate 102 and is flush with the surface of the receiving platform 4 of the side plate 102. The short plate 302 is sleeved on the end plate 103 and is flush with the surface of the receiving platform 4 of the end plate 103. The setting of the receiving platform 4 can make the surface of the cabin on the vehicle flat after the expansion cabin 3 is installed, reducing the probability of transportation accidents caused by the protrusion of the vehicle surface. In this embodiment, the method of setting the receiving platform 4 is adopted. When the cabin carried by the vehicle cannot be widened, the method of opening a groove can also be adopted to ensure that the surface of the cabin is not protruding during transportation after the expansion cabin 3 is installed.

[0043] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 11 A number of guide rods 5 are vertically arranged on the receiving platform 4. In this embodiment, eight guide rods 5 are provided, with two on each side of the cabin body 1. The two guide rods 5 on each side are symmetrically designed. One end of the guide rod 5 is detachably installed on the receiving platform 4, and the other end of the guide rod 5 is inserted into the long plate 301 or the short plate 302 and slides within the long plate 301 or the short plate 302. The guide rod 5 can guide the sliding of the long plate 301 and the short plate 302. A truncated cone 17 is fixed to one end of the guide rod 5 inserted into the receiving platform 4. After the guide rod 5 is inserted into the receiving platform 4, it is fixed by bolts. In this embodiment, the countersunk head of the bolt fixing the guide rod 5 is set on the receiving platform 4. The truncated cone 17 can facilitate the insertion of the guide rod 5 into the insertion hole 19 of the receiving platform 4, and can also facilitate the insertion of the expansion cabin 3 on the ground when it is removed. The guide rod 5 includes a detachable part installed on the receiving platform. The mounting part 51 and the rotating part 52 are hinged on the mounting part 51. A rotating bolt 6 and a rotating nut 7 are embedded between the mounting part 51 and the rotating part 52. The rotating bolt 6 passes through the mounting part 51 and the rotating part 52. The rotating part 52 is rotatably mounted on the mounting part 51 with the rotating bolt 6 as the pivot. The rotating nut 7 is threaded onto the rotating bolt 6. Tightening the rotating nut 7 fixes the rotating part 52 to the mounting part 51. The hinge between the rotating part 52 and the mounting part 51 is achieved by the rotating bolt 6 and the rotating nut 7. The cover plate 303 is removed, and the long plate 301 and the short plate 302 are slid to a position higher than the hinge point between the mounting part 51 and the rotating part 52. By loosening the rotating nut 7, the rotating part 52 can rotate. The rotation drives the rotating part 52 to rotate the long plate 301 or the short plate 302, so that the long plate 301 or the short plate 302 can act as a temporary awning.

[0044] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8Both the long plate 301 and the short plate 302 are slidably provided with several lifting rods 8. In this embodiment, three lifting rods 8 are evenly provided along the length of each of the long plate 301 and the short plate 302. One end of the lifting rod 8 is inserted into the long plate 301 or the short plate 302, and the other end is detachably connected to the cover plate 303. A rotating platform 18 is rotatably provided on the cover plate 303 corresponding to the lifting rod 8. Both ends of the rotating platform 18 penetrate the cover plate 303 and are flush with the cover plate 303. An insertion hole 19 is provided on the rotating platform 18, and the lifting rod 8 is inserted into the insertion hole 19. Several fixing blocks 20 are slidably provided on the side wall of the insertion hole 19. A fixing slot 21 is provided on one side wall of the rotating platform 18. The fixing block 20 slides into the fixing slot 21 to fix the lifting rod 8 to the cover plate 303. A spring is provided between the fixing block 20 and the rotating platform 18. The spring drives the fixing block 20 to slide towards the fixing slot 21. When the rotating platform 18 is driven to rotate, and the fixing slot 21 and the fixing block 20 are aligned, the fixing block 20 is inserted into the fixing slot 21 under the elastic force of the spring. At this time, the lifting rod 8 is fixed to the cover plate 303. Driving the rotating platform 18 to rotate causes the fixing block 20 and the fixing slot 21 to be misaligned. At this time, the lifting rod 8 can... The device can be removed from the rotating platform 18. The rotating platform 18 has a rotating groove on the side away from the insertion hole 19, facilitating the rotation of the rotating platform 18. In this embodiment, four fixing blocks 20 are evenly arranged around the insertion hole 19, and four fixing slots 21 are evenly arranged on the lifting rod 8. The lifting rod 8 is slidably mounted on the long plate 301 or the short plate 302. Bolts are provided on both the long plate 301 and the short plate 302 to fix the lifting rod 8 to its lifting position. In this embodiment, the countersunk heads of the bolts fixing the lifting rod 8 are located on the long plate 301 or the short plate 302. The sliding mounting of the lifting rod 8 can raise the cover plate 303, allowing the container to... The space is further expanded, but the cabin expanded using this method is not sealed. If sealing is required, the cabin can be sealed later by setting curtains or other means. The lifting rod 8 is inserted into one end of the long plate 301 or the short plate 302 and a rotating shaft 9 is fixed thereon. The short plate 302 or the long plate 301 is provided with a guide groove 10 corresponding to the rotating shaft 9. The end of the guide groove 10 away from the receiving platform 4 is provided with a rotation port 11. The lifting rod 8 is rotatably set so that when the long plate 301 or the short plate 302 is used as a canopy, the lifting rod 8 can be rotated so that the end of the lifting rod 8 extends out of the long plate 301 or the short plate 302 and abuts against the cabin body 1 to support the long plate 301 or the short plate 302.

[0045] Reference Figure 2 , Figure 9 and Figure 10Both the side plate 102 and the end plate 103 have vertically formed positioning grooves 12, and the long plate 301 and the short plate 302 are fixedly provided with positioning blocks 13 corresponding to the positioning grooves 12; there are two top plates 104, and the width of each top plate 104 is half that of the bottom plate 101. The two top plates 104 are respectively hinged to the side plate 102; a driving block 14 is slidably disposed on the side plate 102. In this embodiment, the driving block 14 is an L-shaped slider, with one end of the driving block 14 extending into the positioning groove 12, and the other end... One end of the top plate 104 is abutted against. The positioning block 13 slides, causing the driving block 14 to slide. When the positioning block 13 is at the top of the positioning groove 12, the positioning block 13 drives the driving block 14 to slide and drive the top plate 104 to rotate until it is parallel to the side plate 102. The top plate 104, away from the side plate 102, abuts against the cover plate 303. Through the sliding of the driving block 14, when the expansion compartment 3 is expanded, the top plate 104 is driven to rotate and open the connection between the expansion compartment 3 and the compartment body 1. After rotation, 104 can also act as a support for the expansion compartment 3, improving the structural strength of the expansion compartment 3. A return spring 22 is provided between the drive block 14 and the side plate 102. When the positioning block 13 disengages from the drive block 14, the elastic force of the return spring 22 causes the drive block 14 to slide and return to its original position. At this time, the drive block 14 disengages from the top plate 104, and the top plate 104 returns to its original position under its own weight. Since the expansion compartment 3 is detachable, the compartment body 1 needs its own top plate 104 to ensure that the compartment body 1 can become a sealed container independently after the expansion compartment 3 is removed. However, the presence of the top plate 104 will affect the expansion of the container when it is expanded. By using the drive block 14 in conjunction with the positioning block 13, the top plate 104 is driven to rotate and connect the compartment body 1 and the expansion compartment 3 while the expansion compartment 3 is sliding and expanding. This reduces the impact of the top plate 104 on the expansion of the compartment body 1, and also allows the top plate 104 to act as a support for the cover plate 303, improving the structural strength of the expansion compartment 3.

[0046] The implementation principle of this application embodiment is as follows: When the cabin needs to be expanded, the expansion cabin 3 is driven to slide, and the positioning block 13 slides in the positioning groove 12. When the positioning block 13 slides to the top of the positioning groove 12, the positioning block 13 drives the driving block 14 to slide. The driving block 14 abuts against the top plate 104 and rotates. The top plate 104 completes the expansion of the cabin space by rotating and connecting the cabin body 1 and the expansion cabin 3. When the cabin needs to be expanded again, the lifting rod 8 is driven to slide, and the lifting rod 8 drives the cover plate 303 to slide and expand the cabin again. When a canopy needs to be erected around the cabin, the cover plate 303 is removed, and then the long plate 301 or short plate 302 in the direction where the canopy needs to be erected is slid. The long plate 301 or short plate 302 is slid to a position higher than the hinge point between the mounting part 51 and the rotating part 52, and the rotation is loosened. Nut 7 drives the rotating part 52 to rotate the long plate 301 or the short plate 302. After the long plate 301 or the short plate 302 rotates to a horizontal position relative to the ground or with one end away from the main body 1 tilted towards the ground, tighten the rotating nut 7 to fix the long plate 301 or the short plate 302. Then, drive the lifting rod 8 on the long plate 301 or the short plate 302 to slide, so that the rotating shaft 9 slides to the rotating opening 11. Rotate the lifting rod 8 through the rotating shaft 9, so that the lifting rod 8 abuts against the main body 1, and complete the construction of the canopy. When two cabins are needed, the expansion cabin 3 is removed from the main body 1, and the expansion cabin 3 is disassembled and then reassembled in the area where the cabin needs to be installed to form another cabin. By sliding the lifting rod 8 to drive the cover plate 303 to slide, the cabin formed by the expansion cabin 3 can be expanded. Example 2

[0047] The difference between this embodiment and Embodiment 1 is that the installation method of the expansion compartment 3 in this embodiment is different from that in Embodiment 1.

[0048] Reference Figure 13 , Figure 14 and Figure 15The expansion compartment 3 is slidably inserted into the side plate 102. When the expansion compartment 3 is inserted into the compartment body 1, it is flush with the side plate 102. A sliding groove 23 is opened on the bottom plate 101, and a hydraulic cylinder 24 is installed in the sliding groove 23. A sliding block 25 is provided at the bottom of the expansion compartment 3, and the sliding block 25 is slidably disposed in the sliding groove 23. The piston rod of the hydraulic cylinder 24 is detachably connected to the sliding block 25 by bolts. An expansion hole 26 is opened on the side plate 102, and the expansion compartment 3 is inserted into the expansion hole 26. A side slide plate 27 is slidably disposed on the side plate 102, and the side slide plate 27 is embedded in the side plate 102 and flush with the surface of the side plate 102. In this embodiment, the side slide plate 27 has two... A drive spring 28 is provided between the two side slide plates 27 and the side plate 102. The drive spring 28 drives the two side slide plates 27 to slide towards each other. When the expansion compartment 3 is removed from the compartment body 1, the two side slide plates 27 abut against each other and close the expansion hole 26 by the elastic force of the side spring. The side slide plates 27 have a wedge-shaped surface on the side facing each other. When the expansion compartment 3 is installed, the side slide plates 27 are driven to slide by abutting the wedge-shaped surface, thereby opening the expansion hole 26 and allowing the expansion compartment 3 to be inserted into the compartment body 1. A cover plate 29 is provided on the bottom plate 101. The cover plate 29 is driven by a spring to abut against the end of the expansion compartment 3 inserted into the compartment body 1. After the expansion compartment 3 slides, the cover plate 29 covers the sliding groove 23.

[0049] A control method for a multi-purpose vehicle-mounted automated expandable cabin includes: S1: cabin expansion; driving the expandable cabin 3 to slide out of the cabin body 1 to expand the cabin body 1; S2: cabin disassembly; driving the expandable cabin 3 to slide away from the cabin body 1 to disassemble the cabin, and placing the disassembled expandable cabin 3 separately to form a new cabin; S3: cabin storage; installing the disassembled expandable cabin 3 back into the cabin body 1 and storing the expandable cabin 3 back into the cabin body 1 to store the cabin.

[0050] The implementation principle of this application embodiment is as follows: when the cabin needs to be expanded, the expansion cabin 3 is driven to slide, so that the expansion cabin 3 extends out of the cabin body 1, thereby expanding the cabin; when an additional cabin needs to be set up, the connection between the piston rod of the hydraulic cylinder 24 and the sliding block 25 is disassembled, and the expansion cabin 3 is driven to slide away from the cabin body 1 and placed in the required position to form an additional new cabin.
