Description

Technical Field

[0001] The present invention relates to a household vehicle-mounted travel cabin, specifically, a cabin body that can be folded up and carried on the roof of medium or large household vehicles, such as medium or large SUVs, MPVs and other family passenger cars, and unfolded on the ground of a camping site as a hard cabin, with space required for basic living and working activities such as leisure, bathroom, sleeping, simple cooking and dining, etc., and the household vehicle-mounted travel cabin is independent of the vehicle body, so as to meet the needs of modern families for short-term temporary driving and outdoor living and leisure. Technical Background

[0002] For modern families, with the increase of outdoor leisure and self-driving travel activities, some families have purchased RVs. However, for many families, especially young people, the utilization rate of RVs is not high. They are often used occasionally on holidays and idle on weekdays, and occupy parking spaces for a long time. Most of these tall and large RVs that have been idle for a long time cannot be used as daily commuting vehicles for families. They not only take up costs, but also bring troubles. Although trailer RVs have achieved the separation of "house" and "car", the problem of long-term occupation of parking spaces is a big pain point, which makes many citizens and families stay away.

[0003] At present, people often use cloth floor tents for outdoor camping. Although they are easy to carry and use, they are not suitable for use in many outdoor environments. There are serious personal safety issues, and sometimes they are even fatal. In recent years, some hard roof tents have appeared on the market. They are folded and installed on the roof for transportation and unfolded on the roof for use. In view of the limited roof space and the strength of the car, it can only be a small roof sleeping compartment, which is not convenient and comfortable, and cannot play the role of a comfortable family outdoor living life.

[0004] By searching public publications, no top-loading hard-mounted caravans with outdoor living and leisure functions designed specifically for family self-driving travel in ordinary household cars were found, nor was there any precedent for the public use of such caravans. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a comfortable and safe travel warehouse for people who travel by ordinary family cars, which is required for camping, sleeping, bathroom, simple cooking and dining, etc., so that many families can enjoy the outdoor camping life and travel convenience similar to that of RVs without having to buy RVs separately.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: an independent vehicle-mounted travel cabin is set up, and the cabin body adopts a deformable hardware structure, which can be folded and unfolded through various physical transformations such as stacking, telescoping, plugging, containing, rolling up, splitting and splicing. When folded, it is one or several flat boxes, which are placed on the roof of the vehicle for transportation, and are assembled and unfolded for use after arriving at the camping site, so as to realize outdoor camping and living.

[0007] The present invention adopts a method of setting up a top-loaded travel cabin, which enables driving travel and outdoor camping without changing the original appearance of an ordinary family car, so that many families can enjoy the convenience and fun of outdoor living without having to buy a house or car; the cabin body is easy to assemble and fold and unfold, and is usually placed at home, and is only installed in the car when traveling, which does not affect its daily commuting use at all; the deformable design of the cabin body ensures that the family car carrying the cabin body still has good passability; the cabin body is unfolded to the ground to form a warehouse, and its functionality and comfort are incomparable to those of a hard roof tent, and its safety is far better than that of a camping tent.

[0072] To achieve the purpose of the present invention, the travel cabin must have a space size that is almost the size of a small RV compartment after being assembled and unfolded. Its height must be sufficient for an average person to walk upright in the cabin, and it must have a relatively suitable cabin floor area for the family to carry out basic outdoor living and work activities. At the same time, the condensed cabin body must be able to be installed on the roof of many household passenger cars, such as medium and large SUVs, MPVs, etc., and can be carried in compliance with regulations. Therefore, a deformable composite structure must be adopted so that it can be physically shrunk or disassembled immediately and conveniently after use. Therefore, it is a lightweight top-loaded car travel cabin that can be assembled on the spot.

[0073] In this composite structure, the most practical is to design the warehouse body modularly, assembling two or more independent modular units to form the warehouse body. These modules have appropriate size and weight and are easy to carry. These modular units can also be deformable structures. They can be physically assembled and unfolded into warehouses, or they can be reorganized and shrunk through various physical transformations such as folding, shrinking, and mutual disassembly, stacking, buckling, plugging, and inclusion, forming a flat block that is easy to carry and placed on the roof for transportation. Of course, the operation of these physical transformations must be convenient and immediate, otherwise it will not be practical. Here, the shrinkage of the warehouse body can also be formed into several blocks, and some of the blocks may also be placed in the car for storage and transportation. These situations do not need to be discussed too much. The following is only the most important and basic situation of the warehouse body being reorganized and shrunk into a flat carrier placed on the roof for transportation.

[0074] Figures 1 to 28 This is the best embodiment of the present invention, which is an example of a modular composite structure of the travel cabin, and is described in detail in three parts as follows:

[0075] Part 1: The structure of the travel cabin and its modular units

[0076] Figure 1 The top view of the travel cabin 10 in the folded state is a flat square column, with a column 11 at each of its four corners, called a lifting column, which is a screw with a threaded outer surface, correspondingly inserted into each lifting ear plate 12 and control ear plate 13 on the side of the cabin body, and the upper part of the cabin body is supported and driven to rise and fall through the motor power mechanism in each lifting ear plate 12. The DC battery 14 and the circuit device box 16 are arranged on the top of the cabin body, 15 is the battery charging port, 17 is the power switch, 18 is the circuit breaker, 19 is the operating switch plate, 20 is the connecting cable, and 21 is the cable socket. Figure 2 The travel cabin 10 is unfolded at a camping site, and is a closed and safe hardboard cubic cabin. Figure 3 It is a module disassembly diagram of the warehouse body 10. The entire warehouse body 10 is composed of four equivalent modules 1, 2, 3, 4 horizontally spliced ​​in a predetermined sequence, and locked by splicing locks 22 at corresponding positions. These eight splicing locks 22 are all plug-in type password locks, which are composed of a lock head 23 inserted into its corresponding lock seat 24 with a password ring. Figure 3 The lifting column 11 on the middle module 3 is only shown at the bottom to facilitate viewing of the entire diagram. The reason for using four modules is mainly that the module size is appropriate, the weight is reduced, and it is easy to carry and store at home. Of course, there should not be too many modules to avoid complicated splicing.

[0077] These four modules are structurally equivalent and have the same scale. They are all deformable structures that can be expanded and collapsed. The following takes module 2 as an example to explain the module structure in detail:

[0078] See also Figure 3 , 4 5. Each module is formed by buckling an upper half block 30 and a lower half block 40, and is a square box body, which is locked by a buckle lock 25 on the side elevation. The buckle lock 25 has the same structure as the aforementioned splicing lock 22. The upper and lower half blocks 30 and 40 have the same internal structure, and are both composed of a top cover 31 or a bottom cover 41 containing two horizontally stacked warehouse boards 32, 33 or 42, 43, and each warehouse board is a square hard board. Figure 5 The layered structure inside the module is explained in detail: the bottom cover 41 has two edges with facades and intersect at right angles, called buckle groove plates 44 and 45; the other two edges are open and intersect at right angles, which are used to dock with the adjacent modules 1 and 4 respectively. The top cover 31 also has corresponding buckle groove plates 34 and 35 and two docking edges. Since the four modules of the travel cabin must be stacked in two layers during shipment, each module will have an exposed docking opening that needs to be covered. A flap 36 is specially provided as a cover for this opening. It is hinged to the edge of the top cover 31 and can be flipped up and down to open and close this opening of the module.

[0079] The upper body warehouse panels 32, 33 are respectively installed horizontally and in layers on the inner sides of the corresponding top cover buckle groove panels 34, 35 with folding hinges, and the connecting edges are the same length as their buckle groove panels; the lower body warehouse panels 42, 43 are respectively installed horizontally and in layers on the inner sides of the corresponding bottom cover buckle groove panels 44, 45 with folding hinges, and the connecting edges are the same length as their buckle groove panels. From the perspective of horizontal position relationship, the warehouse panels 32, 42 are symmetrically distributed up and down about the buckling surface 00 of the upper and lower blocks 30, 40, and the size scales are equal, and the warehouse panels 33, 43 are the same. They can be flipped up or down 90 degrees from a horizontal position to an upright position and connected in pairs. The so-called buckling surface 00 here is an imaginary plane in the mathematical sense. In the folded state, the upper and lower blocks 30, 40 are buckled together, and the warehouse panels are stacked horizontally. Pads 37, 38, 39, 47, 48, 49, etc. are provided between the panels for positioning and support. In the unfolded state, such as Figure 6 , 7 As shown, the upper half 30 is raised to a high position, and the lower half 40 remains in place. The upper and lower warehouse boards are successively erected in pairs and assembled to form vertical surfaces 51 and 52, which are overlapped at right angles to form a quarter corner of the entire warehouse.

[0080] In order to squeeze and fit tightly, the upper and lower joint edges of the warehouse board are matched with small slopes. The order of splicing is to splice warehouse boards 33 and 43 first: turn down 33 to stand upright, then turn up 43 to overlap it, and the corresponding pads 38 and 48 are placed side by side and fixed with the movable latches 55 on them to form a large warehouse board 51; then splice warehouse boards 32 and 42 to form warehouse board 52. 52 and 51 are overlapped at right angles. The positioning method is: when warehouse board 42 is upright, its positioning sleeve 50 is inserted into the positioning retaining ring 53 on warehouse board 43, and the screw bolt 56 on its pad 49 is screwed into the positioning hole 54 on warehouse board 43 to position it. The outer edges of warehouse boards 51 and 52 are butt-jointed with other modules, and the butt edges are engaged with concave and convex grooves. The fixed latches 57 and 58 set on the pads 37 and 47 position and connect the corresponding warehouse boards when the modules are spliced. Note that the erection, overlap and positioning of the warehouse panels mentioned here only illustrate the splicing relationship of the warehouse panels within one module. In fact, after the four modules are connected to form a whole, the warehouse panels have been connected in pairs to form a large warehouse panel. When the warehouse body is unfolded, they are all erected and connected uniformly, not each module is unfolded separately. In addition, transparent window panels 60 are set on the corresponding cover panels and warehouse panels; a bottom frame for splicing is attached under the bottom cover 41.

[0081] See also Figure 4 The lifting ear plate 12 and the control ear plate 13 are respectively arranged on the outer side of the upper and lower buckle groove plates 34 and 44 near the corners, and can be respectively called the upper ear plate and the lower ear plate. The lifting column 11 vertically passes through the through holes 70 of the upper and lower ear plates 12 and 13 to locate and control the buckling and separation of the upper and lower half blocks 30 and 40. Figure 8 The structural relationship between the lifting column and the upper and lower ear plates is analyzed. As shown in the figure, the cross section of the lifting column 11 is a circular segment, which is consistent with the through hole 70 of the upper and lower ear plates, and passes through the upper and lower ear plates 12 and 13 in a straight line. For easy viewing, only the bottom of the lifting column 11 and its crossing axis are drawn in the figure. The lifting ear plate 12 is relatively large, and a DC motor 72 and a transmission gear 74 are installed on its support plate 71. The transmission gear 74 is a hollow gear ring, which is placed between the upper ear 75 and the lower ear 76 of the support plate, and is passed through by the lifting column 11. Its inner thread is fitted with the thread of the lifting column 11; its outer edge gear teeth are engaged with the motor gear 73. Driven by the motor 72, the transmission gear 74 rotates around the lifting column 11, so that the entire lifting ear plate 12 moves up and down relative to the lifting column 11, thereby realizing the vertical lifting of the entire upper half 30. 77 is an upper ear plate cover.

[0082] The control ear plate 13 on the lower half block 40 has a simple structure. There is only one circular through hole 70 in the center of the plate that matches the lifting column 11, so that the lifting column 11 can move freely up and down therein, so that the lower half block 40 will not be affected by the lifting of the upper half block 30 and will remain at the bottom. When the warehouse is actually unfolded, the lower ear plate 13 and the lifting column 11 are positioned and connected by screwing the positioning bolt 78 into the positioning hole 79 to ensure that the lower half block 40 is at the bottom and does not move during the lifting process of the upper half block 30. At this time, the lowest point of the lifting column 11 is at the same height as the lowest point of the lower half block 40, and they are both on the ground to bear the weight. This position is called the zero position of the lifting column 11, and the zero positions of the four lifting columns are at the same height.

[0083] The lifting column 11 supports and controls the precise expansion and contraction of the warehouse body 10 to ensure the impact resistance of the entire frame. At the same time, during the loading and unloading process, the entire warehouse body 10 must be lifted steadily and some short-distance adjustments and movements must be made. Therefore, a load-bearing universal foot ball 80 is installed at the bottom of each lifting column 11. At the same time, a grounding ring 81 is provided around the end of the lifting column 11 above the foot ball 80. It is a short circular tube, which is usually mounted on the lifting column 11. When needed, it can be stepped on by foot to play a braking and positioning role.

[0084] According to the needs of vehicle loading and storage, each lifting column 11 must be able to turn twice to become three sections. When loading, it should be attached to the bottom of the stacking warehouse body 10, and when storing, it should be attached to the top of the stacking warehouse body 10. Fig.28 To this end, each lifting column 11 is provided with two turning joints at corresponding positions, and a turning square column inner core mechanism is adopted to achieve 90 degree turning and precise resetting to the left and right. The principle and mechanism are as follows Fig. 9 As shown: at the turning joint 90, the upper and lower lifting columns 91 and 92 are tightly connected by a square column inner core 93. This inner core is divided into upper and lower sections 94 and 95, which are connected by a rotating shaft 96 and can be folded 90 degrees relative to each other in both directions. The upper inner core 94 is connected to the upper lifting column 91; the entire inner core 93 is tightly inserted into the square column central plug hole 97 of the lower lifting column 92, and is connected to the bottom of the hole through a return spring 98. Manually pull one of the upper and lower lifting columns 91 and 92 to expose most of the square column inner core 93, and then turn it in two opposite directions at an angle of 90 degrees each. This structure is not only easy to operate, but also can better ensure the connection strength and accuracy.

[0085] Part 2: Assembly and expansion of warehouse

[0086] First, the base frame of the warehouse body 10 is introduced. Fig.10 , 11As shown, a chassis with a horizontal and vertical metal bar structure is attached under each module bottom cover 41. The four chassis structures correspond to each other. When the modules are spliced, the four are connected together by plugging. Each splicing plug 100 extends out of the docking port and is gradually inserted into the corresponding socket 101 of the other party. In fact, it is the docking of the chassis that guides the splicing operation of the modules and modules, and finally integrates them into one.

[0087] According to the stacking relationship during transportation, modules 1 and 2 are called basic modules, and the two are connected to form basic module 5; 3 and 4 are called stacking modules, and the two are connected to form stacking module 6. During shipment, stacking module 6 is stacked on top of basic module 5 to form a complete stacking warehouse body 10 for roof transportation, as detailed in the third part below. Three sleeves 103 for loading and unloading vehicles are installed under the chassis of basic module 5. The structure is a hollow tube with a slit downward, which is used to sleeve on the upper rod 126 of the sliding rod of the roof support bar 120, and is also used as a ground-based load-bearing foot when the warehouse body is spliced. In addition, two slot columns 110 are respectively arranged at appropriate positions on the bottom surfaces of the two basic modules 1 and 2. When the stacking warehouse body 10 is loaded and transported, the folded lifting column 11 is stored and controlled, see Fig.28 Three L-shaped pins 105 are respectively provided under the bottom frame of the stacking modules 3 and 4, which are used to be plugged into the corresponding foot sleeves 106 on the basic module 5 when building the stacking warehouse body 10. They are also the ground-bearing feet when the warehouse body is spliced.

[0088] The splicing of the travel cabin is carried out at the camping site. It should be carried out on a flat and solid level ground. It should not be used in places with potholes, slippery soil, or large slopes. The splicing is divided into two steps: module splicing and module group splicing. First, the module splicing is carried out to form modules 5 and 6. See Figure 3 The operation method is: first confirm that the lifting column 11 of each module is in zero position. Place the corresponding docking interfaces of modules 1 and 2 in parallel, open each open cover plate 36, and then move module 2 closer to module 1 so that its two splicing plugs 100 are gradually inserted into the corresponding jacks 101 of the other party. After observing and confirming that there is no foreign matter in the docking interface and the docking edges of each board are neat and in place, continue to move closer until the top covers 31 of the two are tightly engaged and the concave and convex bite together, and the two ends of the connector 18 on the top cover are plugged in. At this time, the warehouse plates 32 and 42 in module 2 are also engaged with the corresponding warehouse plates in the other module 1 at the same time, and they are spliced ​​together. At the same time, the lock seat 24 of the corresponding splicing lock 22 is also plugged with its lock head 23 at the same time, and the digital ring on the lock seat 24 can be locked. Finally, the fastening hooks 26 set on the inner side of the top cover 31 and the bottom cover 41 are hooked into the corresponding hook mouth 27, and the splicing of the basic module 5 is completed. The splicing of the stacking module 6 is continued in the same way. The second step is to splice the modules, see Fig.12: Module 6 is moved horizontally toward module 5, so that its four splicing plugs 100 are gradually inserted into the corresponding jacks 101 of the other party, until the top cover and the bottom cover of the module are spliced ​​and squeezed respectively. At this time, the compartment plates 33 and 43 in module 6 are also connected one by one with the corresponding compartment plates in the other module 5, and the concave and convex bite together to lock the corresponding splicing locks 22 that have just been inserted, so that the splicing is completed and formed. Figure 1 The entire warehouse body 10 is shown. At this time, the four upper half blocks 30 and the four lower half blocks 40 are respectively connected as a whole, which is called the upper half and the lower half. The entire warehouse body 10 can be regarded as being formed by buckling the upper half and the lower half. Figure 1 It can be seen from the figure that the four lifting columns 11 are not evenly located at the four corners, and the two lifting columns of the basic module 5 are more inclined to the middle position, which can improve the supporting force structure.

[0089] During the module splicing process, the circuit wiring laid in the four top cover 31 layers is connected through two plugged-in disconnectors 18. After the module is spliced, the jumper cable 20 is plugged into the interface 21, and the power supply lines of the four DC motors 72 are all connected, ready for the subsequent electric expansion of the warehouse body. See the circuit device layout and electrical schematic diagram Fig.13 , Fig.14 . In the figure, four control switch buttons SB1, SB2, SB3, and SB4 are arranged in sequence on the SB switch plate 19. All four are normally off switches. Among them, SB3 and SB4 are switches for controlling the synchronous up and down movement of the two lifting columns of the stacking module 6, which are called height adjustment switches and are used when stacking and loading and unloading vehicles; SB1 and SB2 are switches for controlling the synchronous up and down movement of all four lifting columns, which are called lifting and lowering switches and are used when the warehouse is unfolded and folded and when loading and unloading vehicles. M1, M2, M3, and M4 are the DC motors 72 in the lifting ear plates 12 of modules 1, 2, 3, and 4, respectively. The battery 14 supplies power to the circuit through the power supply switch 17. The fuses FR1, FR2, FR3, and FR4 in the circuit provide the circuit with automatic protective power-off function. Once an erroneous operation such as pressing the wrong button occurs, each switch button will immediately fail and the circuit will be powered off.

[0090] After the warehouse body is assembled, it can be unfolded. The warehouse body unfolding is divided into two steps: electric lifting and manual splicing. Fig.15 , 16, 17, 18, and 19, the first step: first confirm that the four lifting columns 11 are upright at zero position and locked with the lower body, and step on the ground ring 81 at the bottom of each lifting column to stabilize the entire warehouse body 10 on the ground. Turn the password ring to make all four snap locks 25 unlocked, so that the entire upper body and the lower body can be separated. Next, start the electric top lifting: press the power switch button 17, the circuit is energized, and press the top lifting switch button SB1 on the switch plate 19 by hand. The four motors M1, M2, M3, and M4 begin to rotate synchronously in the forward direction, and the upper body begins to rise steadily. When the predetermined upper limit is reached, release the button, all motors stop, and the upper body stays at the highest position. Note that if the button is not released in time after reaching the upper limit, it is not a big deal. The motor circuit will automatically cut off the power immediately under the protection of its fuse, and the motor will actually stop running. After completing the top lifting, press the button 17 again to disconnect the power supply to ensure the safety of the following manual operations and camping activities. The second step is to manually splice the warehouse panels: first splice the two parallel and opposite warehouse body facades where the warehouse panels 33 and 43 are located, and then splice the other two parallel and opposite warehouse body facades where the warehouse panels 32 and 42 are located, thereby completing the deployment of the entire travel warehouse 10.

[0091] According to the reverse order of the splicing operation and the unfolding operation, the folding and disassembling of the travel cabin 10 can be completed. When folding and lowering the roof, the roof lowering switch SB2 button on the switch plate 19 needs to be pressed. If an error occurs by accident, and other switch buttons are pressed or the roof lowering switch SB2 is pressed without folding the cabin board, it is not a big deal. Due to the excessive rotation resistance of the motor, a circuit fuse will quickly operate to cut off the circuit, and the motor will not actually run.

[0092] Note that when the warehouse body 10 is spliced ​​together and in the stacked state described below, it can be moved over a short distance. At this time, electric operation is required. First, the warehouse body 10 is slightly raised so that its bottom is off the ground and it can be moved only by the foot balls 80 of the four lifting columns 11 supporting it on the ground.

[0093] like Fig.19 , 20 As shown, two longitudinally flipping door panels 107 and 108 are installed on the corresponding warehouse panels 32 and 42, and the two are connected to form a warehouse door 109. A set of special booth facilities is configured, including a folding table 111 and two folding combination chairs 112 and 113, which are placed on the bottom cover of the warehouse and fixed with a number of preset positioning holes 114 for leisure, cooking, dining, etc.; when sleeping, they can be adjusted to a bed on the spot; after use, the booth table and chair legs are folded up and placed on the bottom cover of the warehouse on the spot, which does not affect the folding and disassembly of the warehouse body. Because the lower half is thicker than the upper half, some storage space is left on the upper part of the bottom cover. Bathing tents, toilets and other bathroom facilities, as well as bedding, water buckets, induction cookers and other cooking utensils are separately configured on the vehicle.

[0094] Part 3: Module stacking and loading and unloading operations

[0095] In this example, the four modules are stacked in two layers after being disassembled to form a stacking bin 10, which is loaded and transported as a whole. The stacking should be carried out in a suitable, firm and flat position on the right side of the vehicle. Fig.21 , 22 As shown, in the disassembled state, the lifting columns 11 of each module are erected and confirmed to be in zero position. First, the basic modules 1 and 2 are spliced ​​to form the basic module 5, and it is placed along the longitudinal direction of the vehicle body. Then, the modules 3 and 4 are translated one by one on the module 5 along the longitudinal direction from the two outer ends to the center, so that the pins 105 at the bottom are inserted into the corresponding foot sleeves 106 on the basic module 5, and the modules 3 and 4 are spliced ​​on the basic module 5 to form the stacking module 6. At this point, the four modules form the stacking warehouse 10, and finally the cable 20 is inserted into the interface 21 to connect the circuit.

[0096] The loading operation requires the use of three roof support bars, each of which has the same structure, such as Fig.23 As shown: the roof support bar 120 is composed of a support rod 121 and a slide bar 122. The support rod 121 is a hollow metal groove tube with a slit 123 on the top to cover the lower rod 125 of the slide bar 122. The two ends have height-adjustable end feet 124 that bite into the original load-bearing bar 130 on the roof, fixing the support rod 121 on the roof and changing its position forward and backward to adapt to the docking warehouse body 10; the slide bar 122 is a conjoined double-rod metal rod, the lower rod 125 of which is controlled to slide in the support rod 121, and the upper rod 126 is used to slide into the sleeve 103 at the bottom of the warehouse body 10 to overlap and control the warehouse body. A groove line 127 is opened on the top surface of the upper rod 126 for the anti-drop latch 128 on the bottom sleeve 103 of the warehouse described below. Three independent support bars 120 are arranged front and back and across the roof. According to the bending of the roof load-bearing bar 130 and the need to dock the warehouse body 10, the front and rear positions of each support bar and the height of the end feet 124 are adjusted and determined so that the three support bars 120 are at the same height to receive the warehouse body 10. Of course, after the first use, the three support bars 120 have been positioned and marked, and no adjustment is required every time.

[0097] The whole loading operation is divided into three steps, see Fig. 22 , 24 , 25, 26, 27:

[0098] The first step is to calibrate the height of the lifting columns: the four lifting columns 11 of the stacked warehouse 10 are all at zero position, and the two lifting columns of the upper stacking module 6 are off the ground. They must be brought to the ground to achieve the same height of the four columns. This is called the height calibration of the lifting columns. The operation method is: first unscrew the positioning bolts 78 to unlock all four lifting columns 11, then press the height calibration switch button SB4, and release the button when the two lifting columns 11 of the module 6 are on the ground. The second step is electric lifting: press the top lifting switch button SB1, and the entire stacked warehouse 10 begins to rise. Release the button after reaching the appropriate loading height. Note that the rising height of the stacked warehouse 10 is also limited by the upper limit at this time, and will not exceed the highest position of the upper half when the warehouse is unfolded. Within this range, the height of the warehouse can be adjusted using the top lifting and lowering switches SB1 and SB2 to make the warehouse chassis and the roof support bar 120 basically the same height. The third step is overlapping and handing over: pull out the slide bar 122 of the three supporting bars 120 on the roof, and use it as a reference to fine-tune the height of the stacked warehouse body 10 and its position relative to the vehicle body, accurately insert the outer end of the upper rod 126 of the slide bar into the corresponding warehouse bottom sleeve 103 one by one, and push down the anti-disconnection latch 128 installed at the end of the sleeve 103 to limit the possibility of the two being separated, so as to complete the warehouse-car overlap. At this time, the two lifting columns of the basic module 5 are on the inside, and they are first folded up and attached to the warehouse bottom, so that the warehouse body 10 is only supported by the slide bar 122 and the two lifting columns of the stacking module 6, and then slowly push the warehouse body 10 to move parallel to the vehicle body. When part of it moves above the roof, the two lifting columns of the stacking module 6 can be folded, and the warehouse body is completely handed over to the three supporting bars 120 for support and control. Then continue to push the warehouse body 10 to the predetermined final position in the center of the roof, and use a shipping lock seat 132 specially provided on the original load-bearing bar 130 on the roof to combine and lock the shipping lock head 131 on the warehouse body bottom cover, so that the loading is completed.

[0099] The four lifting columns 11 are folded and attached to the bottom surface of the stacking bin 10. Fig.28 .

[0100] The unloading operation can be performed in the reverse order of the above steps, using the roof lowering switch button SB2 and the height adjustment switch SB3 on the switch panel 19 to operate.

[0101] Note that after the stacked warehouse bodies 10 are unloaded from the vehicle and landed, no matter they are to be spliced ​​for use or disassembled and transported indoors for storage, the lifting columns 11 must be placed at zero position to ensure that various subsequent operations can be carried out normally.

[0102] Obviously, the modular structure of the warehouse body can be varied, whether it is the number, shape and whether the modules are isomorphic, the structural mechanism, condensation and expansion methods of the modules, or the methods of their mutual combination, etc., all of which are diverse and cannot be used to limit the scope of the present invention.

[0103] Figures 29 to 38 This is another embodiment of the present invention, in which the warehouse body 600 does not adopt a modular structure, but is designed as a composite whole, which can be folded and unfolded manually, and is briefly described as follows:

[0104] Fig.29 In the case where the travel cabin 600 is placed on the roof of a vehicle, the cabin body 600 is a flat square box body in the folded state, which is formed by the inner box 200 and the outer box 300 being nested together, both of which are flat square boxes with similar dimensions. Each of them has an open side, which is a nesting opening, and the inner box 200 is nested into the outer box 300 to form a closed cabin body 600. Fig.30 This is a top view of the separated inner and outer boxes. Fig.31 The inner box 200 is controlled to be inserted into the outer box 300 by two slide bars 230, 231, which are horizontally installed on the inner box back 201, and are inserted into the corresponding slideways 330, 331 on the outer box back 301 from the bottom and the middle upper part, so as to control the inner box 200 to be inserted into the outer box 300 and slide within a limited range, so as to realize the extension and retraction of the compartment body.

[0105] The structure of the inner box 200 is the same as that of the outer box 300, and the inner box 200 is now taken as an example for description. Fig.32 The structure diagram of the unfolded inner box 200 is composed of three parts: a box back 201, an upper cover 210, and a lower cover 220. The box back 201 is in a square groove shape. Except for the side of the sleeve, the other three sides are respectively surrounded by an upper groove plate 202, a right groove plate 203, and a lower groove plate 204. The lower cover 220 is folded by a mother plate 221 and an extension plate 222, and is connected to the outer edge of the lower groove plate 204 by a hinge. It can be turned down to a horizontal position and unfolded. A folding support rod 206 is provided on the outer side to support it, forming a half of the warehouse bottom of the travel warehouse; the structure, size, and position of the upper cover 210 and the lower cover 220 are completely symmetrical, and it forms a half of the warehouse top after being turned over and unfolded.

[0106] Fig.33 The structure of the inner and outer boxes 200 and 300 of the travel warehouse being stretched out and the upper and lower covers being spliced ​​and unfolded is shown in perspective. In actual use, the warehouse body stands upright on the ground when unloaded from the roof, and is unfolded under the steady control of a special loading and unloading rack: the inner box 200 is pulled outward from the outer box 300 to slide to the farthest position, the upper and lower covers 310 and 320 of the outer box 300 are opened and unfolded for the second time, and then the upper and lower covers 210 and 220 of the inner box 200 are opened and unfolded respectively, and spliced ​​into a surface corresponding to the former, and fixed with hooks 280 and 281 respectively, so as to form a complete warehouse top and bottom.

[0107] As can be seen from the figure, two sets of rolling curtains 250, 251 made of hard slats are vertically installed in the inner box back 201, and the upper and lower ends of the central reels 253, 254 are fixed on the upper and lower groove plates 202, 204 respectively through bearings. They are used to be pulled out and unfolded along the groove slides 282, 283 and 284, 285 set on the inner edges of the warehouse top and bottom, forming the three vertical surfaces of the warehouse body. After the top and bottom are assembled, the rolling curtain wall operation is carried out. Fig.34 As shown: first unfold the rolling curtain 250, pull its outer end along the upper and lower guides 284, 285 into the main slides 282, 283, until it overlaps and fixes with the left groove plate 303 of the outer box 300, and its tail end has been pulled out and separated from its reel 253; then pull out the outer end of the rolling curtain 251, unfold along the main slides 282, 283, until its front end reaches the tail end of the rolling curtain 250, at which time its tail end is still fixed on its reel 254, so that the two groups of rolling curtains 250, 251 unfold into a wall, completing three open closed enclosures to form a warehouse 600. The tail of the rolling curtain 250 is used as a warehouse door, and this section of the groove slide can be rotated inward horizontally, called the door groove 290, corresponding to the upper and lower parts, clamping the tail of the rolling curtain 250 to form a warehouse door 291. In addition, a rechargeable battery 240 is installed on the right groove plate 203 of the inner box 200, which is used as a power source for lighting in the warehouse. Two flaps 340 and 341 are provided on the left groove plate 303 of the outer box 300. When the warehouse body 600 is folded for transportation, the internal space here can be used for appropriate storage.

[0108] The loading and unloading of the warehouse body 600 is completed by using a special loading and unloading frame, the structure of which is as follows: Fig.35 As shown, it is divided into two layers, upper and lower, which are connected as a whole through a turntable structure. The lower frame 500 is a fixed frame in a well shape. Its two horizontal bars 501 and 502 are mounted on two original load-bearing bars 580 on the roof through their end feet. The front and rear positions and heights can be adjusted appropriately, and they are the load-bearing main body. Two longitudinal bars 503 and 504 are arranged in parallel on the horizontal bars. A load-bearing chassis 555 is provided at the connection between the horizontal bar 501 and the longitudinal bar 504, which is used to combine with the turntable 444 of the upper frame 400. The two are sleeved together with the chassis center axis 550 as the rotating shaft to form a load-bearing turntable structure. A groove slideway 560 slightly longer than a quarter of a circle is arranged on the well frame, and its slit faces upward, which is used to bite, support, and control the sliding of the three downward sliding legs 461, 462, and 463 of the upper frame 400. The slideway 560 is divided into three sections 561, 562, and 563, which are separated by partitions and are not connected to each other, called limit plates 564 and 565. The slideways 561 and 563 at both ends are very short and open at the ends, respectively allowing the sliding legs 461 and 463 to slide in and out; the middle section 562 is 90 degrees in arc length for the sliding leg 462, which is limited to slide on a horizontal circular track with a 90-degree arc length between the two limit plates 564 and 565 in the slideway.

[0109] Near one end of the slideway 560 close to the limit plate 564, a positioning bolt 566 is provided. When the upper frame 400 is in the longitudinal standard position, the sliding leg 462 abuts against the limit plate 564. At this time, the positioning bolt 566 is screwed in and extends into the groove to卡住 the sliding leg 462 and make it immovable, so as to longitudinally fix the upper frame 400 and the entire bin body 600 on the roof of the vehicle.

[0110] The upper frame 400 is a rotating frame used to connect and control the bin body 600, so that it can horizontally rotate 90 degrees on the roof of the vehicle, adjust the longitudinal and transverse directions, and when loading and unloading the vehicle, the bin body can be turned up and down on the right side of the vehicle body. The upper frame 400 is in the shape of a Chinese character 'Ri', formed by connecting three cross bars 401, 402, 403 with two longitudinal bars 404, 405. At the connection between the middle of the longitudinal bar 405 and the cross bar 402 is a turntable 444 with a circular hole in the center, which is used to fit with the load-bearing chassis 555 of the lower frame 500. At the corresponding positions of the longitudinal bars and cross bars, sliding legs 461, 462, 463 are set downward. The three are equidistant from the axis of the chassis central axis 550. The sliding leg 462 extends into the arc slideway 562 of the lower frame and slides in the 562 as the upper frame rotates. The sliding legs 461, 463 can respectively enter and exit the short slideways 561, 563. They jointly assist the above turntable structure to support, control and limit the upper frame 400 to rotate smoothly horizontally within the limited range, and then drive the bin body 600 to smoothly perform longitudinal and transverse conversion on the roof of the vehicle.

[0111] At both ends of the cross bar 403, handles 410, 411 are provided, which are short groove pipes with ears and respectively bite on the two back beams 380, 381 of the bin body 600 and are sealed with locking bolts 412, 413. When the locking bolts 412, 413 are screwed in, the back beams 380, 381 can only slide along the groove and cannot be detached, and can also be locked when needed; when the locking bolts 412, 413 are unscrewed, the bin body 600 can be detached from the upper frame 400 and stored in the room. The ears of the two handles 410, 411 are rotatable rings sleeved on the cross bar 403. In this way, under the control of the two handles 410, 411, the bin body 600 can turn up and down around the cross bar 403 and can move back and forth parallel on the upper frame 400 to meet the requirements of loading and unloading the vehicle. The two back beams 380, 381 of the bin body 600 are hollow round bars, which are vertically installed on the back of the outer box, arranged left and right, at the outermost layer of the bin body, and their two ends are fixed by pads. In order to firmly place the bin body 600 on the upper frame 400, anchoring bolts 420, 421 are provided at both ends of the cross bar 401, which can be respectively inserted into the openings at the tops of the two back beams 380, 381 to anchor the bin body.

[0112] The following describes the operation method of the bin body 600 when it lands: Refer to Fig.36 、 37, unscrew the positioning bolt 566, push the warehouse body 600 to rotate 90 degrees counterclockwise horizontally; loosen the blocking bolts 412, 413 on the upper frame 400 to allow the warehouse body 600 to slide, stand on the right side of the vehicle body, grab the back beam 380 or 381 of the warehouse body, and slowly pull the warehouse body outward horizontally until it gradually loses balance on the upper frame 400 and the outer end begins to turn down, then lower it and stand it upright on the ground, then tighten the blocking bolts 412, 413 to complete the landing operation. After that, it can be deployed for use, such as Fig.38 The loading operation is carried out in the reverse order as described above and will not be described in detail.

[0113] As can be seen from the above, this integrated structure still has a large volume and heavy weight when folded, which makes it inconvenient to carry, load and unload, and store. Obviously, there are many structures that can be used for top-loading warehouses. The above is just a simple example. However, no matter what structure is used, as long as it is an integrated warehouse that can be used for basic travel, living and work, the above disadvantages are inevitable. Therefore, it is necessary to use a modular warehouse as in the first embodiment.
