[0103] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. The front and rear directions and the longitudinal direction described herein are the same horizontal direction, and the left and right directions and the transverse direction are the same horizontal direction. The horizontal direction is the direction parallel to the floor. The front and rear directions described herein are the Front-Back directions in the figure, and the left and right directions are the Left-Right directions in the figure. Relative to the vehicle that carries the vehicle-mounted room, the front and rear directions can be the vehicle length direction or the vehicle width direction or any horizontal direction that is at an angle to both the vehicle width direction and the vehicle length direction. "Front" and "rear" are relative and can be swapped. "Left" and "right" are relative and can be swapped.

[0104] like Figure 1 The vehicle-mounted room includes: side walls (10-40), a roof 50, a floor 60, a floor unfolding and retracting mechanism 70 for unfolding and retracting the floor, a lifting mechanism 80 for raising and lowering the roof, a facility component 90, a supporting mechanism 100 for supporting and stabilizing, a side wall unfolding and retracting mechanism 110 for unfolding and retracting the side walls, and a side door 120 installed on the side wall.

[0105] Figure 1-Figure 3 The unfolded state of the car-mounted house is demonstrated. When the car-mounted house is unfolded, people can walk upright in the house without bending over. The room is spacious and can meet various needs such as rest, entertainment, cooking, dining, and showering.

[0106] Figure 1 and Figure 2 The two unfolding states of an embodiment of the car house are shown. In this embodiment, the side wall has an upper wall X1 and a lower wall X2. The upper wall X1 can slide up and down. The user can flexibly adjust the upper and lower positions of the upper wall X1 according to needs. For example, the upper wall X1 can be slid upward to a position in contact with the roof to achieve Figure 1 In the unfolded state shown, the vehicle-mounted room is in the form of an ordinary house structure. The upper wall X1 can also be slid downward to a position a distance away from the roof 50 to achieve Figure 2 In the unfolded state shown, the house is in a fence structure, the room can be ventilated smoothly and the user can have a clear view in the room.

[0107] Figure 3 The embodiment of the vehicle-mounted room is shown in an unfolded state. Of course, the embodiment can also realize the above two unfolded states. Figure 1 and Figure 2One point of the embodiment is that the facility composition of this embodiment comprises a first facility box 901a and a second facility box 901b. After the vehicle-mounted room is stored, some facilities that are relatively high and not convenient for stacking can be accommodated in the first facility box 901a and the second facility box 901b. After the vehicle-mounted room is unfolded, these facilities can slide from the box into the interior of the vehicle-mounted room.

[0108] Figure 4-Figure 6 The vehicle room is shown in its stowed state. In this stowed state, all components, except for the facility boxes (901a, 901b), the box seats 905, and the living facilities within the boxes, are stacked layer by layer to form a stacked structure. The stowed vehicle room meets the roof height limit and floor space requirements.

[0109] Figure 4 and Figure 5 Shown Figure 1 There are two storage states of the car room. Figure 4 The vehicle compartment is in the first storage state. Figure 4 The third sleeve 71f of the middle floor extension and retraction mechanism resists the stacked structure above. There is a certain distance between the stacked structure above and the frame formed by the third sleeve 71f. Figure 4 (the middle and short arrow position), when the third sleeve 71f is automatically Figure 4 The position shown along Figure 4 After the middle dotted arrow moves forward for a distance, it no longer blocks the stacked structure above. At this time, at least part of the stacked structure above falls into the frame formed by the third sleeve 71f, achieving Figure 5 The second storage position is shown. The height H1 of the storage body in the first storage position is higher than the height H2 of the storage body in the second storage position, but both meet the height limit for roof storage. The length L1 of the storage body in the first storage position is shorter than the length L2 of the storage body in the second storage position. Users can freely choose the storage position based on their needs and the vehicle type. For example, the first storage position is more advantageous when installed in a car or pickup truck.

[0110] Figure 6 Shown Figure 3 The embodiment can also realize the above two storage states. In this embodiment, after storage, the facility box and the box seat are located on one side of the stacking body. The total height of the facility box and the box seat is basically the same as the total height of the stacking body, which meets the height limit requirements for rooftop items.

[0111] Here are some examples Figure 3 The general storage steps of the car room,

[0112] First, put the facilities that are difficult to stack into the facility box, and then put the facilities that are easy to stack into a position parallel to the side wall or floor;

[0113] Then, the side wall deployment mechanism is used to rotate and store part of the side wall together with the facility components parallel to it and stack them on the floor;

[0114] Then, the roof is lowered by the lifting mechanism to a position parallel to the floor or the components stacked on the floor. During this process, the remaining side walls and side doors are also stored along with the roof to a position parallel to the floor or the components stacked on the floor.

[0115] After completing the above steps, the roof, side walls and some facilities are stored into four stacked layers; Figure 7 In this embodiment, the floor has four floor panels (61-64), four stacked bodies ( Figure 7 (not shown) are respectively stacked and supported on four floor panels of the floor;

[0116] Then, the support device is stored, and the components of the support device are stored to a position substantially parallel to the floor, and the support device after storage remains connected to the floor or the floor expansion and retraction mechanism;

[0117] Then, the floor unfolding and retracting mechanism is used to store the four floor panels, so that the four floor panels together with the four stacking bodies supported thereon and the supporting devices connected thereto are stacked together. Figure 6 The stacked state shown.

[0118] It should be noted that the above steps are merely schematic illustrations of the storage process and do not necessarily imply that the storage process must be performed in accordance with the above steps. During actual storage, the order of the storage steps can be flexibly adjusted, and steps can be added or reduced as needed. Similarly, the deployment process can be performed in the reverse order of the above storage process, and the order of the deployment steps can be flexibly adjusted, and steps can be added or reduced as needed.

[0119] The vehicle-mounted room provided in this application has a large internal space when unfolded, which meets the needs of people walking upright in the room and various life needs. When folded, it has a small volume, which meets the height limit requirements and flat area requirements for roof objects. In addition, it has high stability and strong wind resistance when unfolded, and the unfolding and folding operations are simple, labor-saving and convenient.

[0120] The following will describe the various parts of the car-mounted room in detail with reference to the embodiments of the accompanying drawings to help understand the implementation method of this application and its core idea. It should be noted that the embodiments of the accompanying drawings are only specific examples of this application and are only used to help understand the method of this application and its core idea. For ordinary technicians in this technical field, without departing from the core idea of ​​this application, several improvements and modifications can be made to this application, and these improvements and modifications also fall within the scope of protection of the claims of this application.

The third connecting portion 72a and the fourth connecting portion 72b of one second connecting device 72 respectively connect the second floor panel 62 and the first floor panel 61. The third connecting portion 72a and the fourth connecting portion 72b of the other second connecting device 72 respectively connect the fourth floor panel 64 and the third floor panel 63. Furthermore, the third connecting portion 72a and the fourth connecting portion 72b of each second connecting device 72 are connected and can slide relative to the fourth connecting portion 72b in a transverse direction (transverse direction refers to the left-right direction in the figure). When the third connecting portion 72a of the two second connecting devices 72 slide relative to the fourth connecting portion 72b, they can drive the second floor panel 62 and the fourth floor panel 64 to slide. Figure 16 In the embodiment, the third connection portions 72a of the two second connection devices 72 slide leftward relative to the fourth connection portions 72b, driving the second floor panel 62 to slide from above the first floor panel 61 to the left of the first floor panel 61, and driving the fourth floor panel 64 to slide from above the third floor panel 63 to the left of the third floor panel 63.

[0127] like Figure 11 The first connecting portion 71a and the second connecting portion 71b each include two parallel sliding members 701. The two sliding members 701 of the first connecting portion 71a are respectively slidably guided with the two sliding members 701 of the second connecting portion 71b to achieve relative sliding connection between the first connecting portion 71a and the second connecting portion 71b. Figure 16 The third connecting part 72a and the fourth connecting part 72b each include two sliding members 701 parallel to each other. The two sliding members 701 of the third connecting part 72a are respectively slidably guided with the two sliding members 701 of the fourth connecting part 72b to achieve relative sliding connection between the third connecting part 72a and the fourth connecting part 72b.

[0128] The sliding member 701 of the first connecting portion 71a and the sliding member 701 of the second connecting portion 71b can be directly slidably guided and matched, or can be indirectly slidably guided and matched through the transition member 703. Figure 12In an indirect sliding and guiding arrangement, the transition member 703 engages with the sliding member 701 of the first connecting portion 71a in a sliding and guiding manner, while the sliding member 701 of the second connecting portion 71b engages with the transition member 703 in a sliding and guiding manner. Thus, when the second connecting portion 71b slides rearward, the transition member 703 and the second connecting portion 71b initially slide rearward together. When the transition member 703 slides rearward to its limit, the second connecting portion 71b continues to slide rearward along the transition member 703. Similarly, the sliding member 701 of the third connecting portion 72a and the sliding member 701 of the fourth connecting portion 72b can also engage with each other directly or indirectly through the transition member 703. This indirect guiding arrangement satisfies the requirements for unfolding the floorboard while ensuring a shorter length when stowed.

[0129] like Figure 11 , both the first connecting portion 71a and the second connecting portion 71b include a lifting member, or only one of them includes a lifting member. Figure 16 The third connecting portion 72a also includes a lifting member. The lifting member can be a swing arm 702. The lower end of the swing arm 702 can be hinged to the sliding member 701 of the connecting portion.

[0130] During the expansion process, Figure 15 When the second floor panel assembly 60b slides to the rear side of the first floor panel assembly 60a, the two sets of floor panel assemblies can be brought to the same height by swinging the swing arm 702 of the first connecting portion 71a and the swing arm 702 of the second connecting portion 71b. Figure 7 When the second floor panel 62 slides to the left of the first floor panel 61 and the fourth floor panel 64 slides to the left of the third floor panel 63, the four floor panels can be brought to the same height by swinging the swing arm 702 of the third connecting portion 72a.

[0131] This floorboard deployment and retraction mechanism utilizes sliding connections to facilitate floorboard deployment and retraction, making deployment and retraction both labor-saving and rapid. The first and second connection devices of the floorboard deployment and retraction mechanism cooperate to enable the floorboard to be deployed and retracted in two or more directions. This ensures that the floorboard has a sufficiently large area when deployed and a sufficiently small area when retracted, meeting the required floor area for rooftop storage.

[0132] like Figure 11 The first connecting portion 71a and the second connecting portion 71b may further be provided with a connecting shaft 704, which is connected to the upper end of the swing arm 702 and extends in the transverse direction. In the illustrated embodiment, the first connecting portion 71a and the second connecting portion 71b are each provided with two connecting shafts 704. Figure 14The first floor panel 61 may be provided with sliding shoes 65 on the front and rear sides. The sliding shoes 65 are slidably guided by the two connecting shafts 704 of the first connecting portion 71a. Thus, the first floor panel 61 can slide left and right along the connecting shafts 704 of the first connecting portion 71a. Similarly, the third floor panel 63 may be provided with sliding shoes 65 on the front and rear sides. The sliding shoes 65 are slidably guided by the two connecting shafts 704 of the second connecting portion 71b. Thus, the third floor panel 63 can slide left and right along the connecting shafts 704 of the second connecting portion 71b. In this way, Figure 16 Before the second and fourth floor panels 62, 64 slide to the left and unfold, the first and third floor panels 61, 63 can be slid to the right a certain distance. In this way, after the four floor panels are unfolded, the joints between the first and second floor panels 61, 62, and the joints between the third and fourth floor panels 63, 64 can be basically located near the left-right center line of the first connecting device 71, ensuring that the vehicle cabin does not excessively deviate to one side of the vehicle after the roof is unfolded.

[0133] In addition, if Figure 7 Sliding shoes 65 may also be provided on the front and rear sides of the second and fourth floor panels 62, 64. When the swing arm 702 of the third connecting portion 72a is swung so that the second and fourth floor panels 62, 64 are at the same height as the first and third floor panels 61, 63, the sliding shoes 65 on the front and rear sides of the second and fourth floor panels 62, 64 are respectively clamped onto the connecting shaft 704, thereby obtaining support and being able to slide along the connecting shaft 704.

[0134] Allowing the floor panels to slide along the connecting shafts 704 allows the floor panels to be closer to the outside of the vehicle, allowing the user to easily remove or install the floor panels and the stacked objects on them from or onto the vehicle roof while standing on the side of the vehicle. Furthermore, the floor panels can be removed or installed in batches, resulting in a lighter load for each removal or installation.

[0135] For example, when removing it from the roof, you can follow the steps below:

[0136] First, slide the second connecting portion 71b and the second set of floor panel assemblies 60b thereon toward the rear of the first connecting portion 71a. Then, use the swing arm 702 to lower the second set of floor panel assemblies 60b to the same height as the first set of floor panel assemblies 60a on the first connecting portion 71a.

[0137] Then, slide the second floor panel 62 and the fourth floor panel 64 along the corresponding connecting shafts to one side of the vehicle;

[0138] Then, remove the fourth floor panel 64, the third connecting portion 72a connected to the fourth floor panel 64, and the stacked body supported on the fourth floor panel 64 from the vehicle side;

[0139] Then, remove the second floor panel 62, the third connecting portion 72a connected to the second floor panel 62, and the stacked body supported on the second floor panel 62 from one side of the vehicle;

[0140] Then, slide the third floor panel 63 and the first floor panel 61 toward one side of the vehicle along the corresponding connecting shafts;

[0141] Then, remove the third floor panel 63, the fourth sliding portion 72b connected to the third floor panel 63, the second sliding portion 71b, and the stacked body supported on the third floor panel 63 from the vehicle side;

[0142] Then, remove the first floor panel 61, the fourth connecting portion 72b connected to the first floor panel 61, the first connecting portion 71a, and the stacked body supported on the first floor panel 61 from the vehicle side;

[0143] After removal, the first connecting portion 71a and the second connecting portion 71b are slid together, and the third connecting portion 72a and the fourth connecting portion 72b are slid together. The blocks can also be pulled away for storage by the movable pulley (not shown) on the floor panel.

[0144] like Figure 11 The first connecting device 71 may also be provided with a plurality of sleeves extending in the transverse direction. In the illustrated embodiment, three sleeves are provided, namely, the first sleeve 71d, the second sleeve 71e and the third sleeve 71f. Figure 17 The tops of the main legs 101a of the floor support device 101 are connected to slide bars 101d. When the vehicle cabin is deployed, the slide bars 101d at the tops of the three rows of main legs 101a are respectively inserted into three sleeves. The three rows of main legs 101a are spaced apart in the front-to-back direction to ensure support stability. The lower end of the swing arm 702 can also be hinged to the sleeve.

[0145] like Figure 11 The first sleeve 71d is connected between the two sliding members 701 of the first connecting portion 71a, the second sleeve 71e is located at the rear side of the first sleeve 71d, the second sleeve 71e is connected between the two sliding members 701 of the second connecting portion 71b, and the third sleeve 71f is located at the front side of the first sleeve 71d.

[0146] Specifically, the third sleeve 71f has two connection modes: Figure 13 In the embodiment, the third sleeve 71f is connected between the two sliding members 701 of the first connecting portion 71a. Figure 11In the figure, the first connecting device 71 is provided with a fifth connecting part 71c, and the fifth connecting part 71c includes two sliding members 701 parallel to each other. The two sliding members 701 of the fifth connecting part 71c are respectively matched with the two sliding members 701 of the first connecting part 71a for sliding guidance, and can slide back and forth relative to the first connecting part 71a. The third sleeve 71f is connected between the two sliding members 701 of the fifth connecting part 71c.

[0147] The third sleeve 71f is connected between the two sliding members 701 of the fifth connecting portion 71c. This allows the position of the third sleeve 71f, the sliding rod 101d inserted into the third sleeve 71f, and the main leg 101a connected to the sliding rod 101d to be changed by sliding the fifth connecting portion 71c. Furthermore, the third sleeve 71f can be used to limit the swing angle of the swing arm 702 of the first connecting portion 71a, allowing the vehicle compartment to adopt two storage positions.

[0148] Specifically, if Figure 4 and Figure 9 When the fifth connecting portion 71c slides backward relative to the first connecting portion 71a to the limit position, the third sleeve 71f acts as a stop for the swing arm 702 of the first connecting portion 71a, or through similar means, the swing arm 702 of the first connecting portion 71a cannot continue to swing downward after swinging to the position shown in the figure. Therefore, the swing arm 702 of the first connecting portion 71a and the floor panel supported thereon can only be stored to the limit position. Figure 4 The first storage state shown in FIG. 7 is not able to fall into the frame enclosed by the third sleeve 71 f, the two sliding members 701 of the first connecting portion 71 a and the first sleeve 71 d.

[0149] like Figure 5 and Figure 10 After the fifth connecting portion 71c slides forward relative to the first connecting portion 71a for a certain distance, the third sleeve 71f no longer blocks the swing arm 702 of the first connecting portion 71a. Sufficient space remains between the first sleeve 71 and the third sleeve 71f, allowing the swing arm 702 of the first connecting portion 71a to swing into the frame formed by the third sleeve 71f, the two sliding members 701 of the first connecting portion 71a, and the first sleeve 71d. Accordingly, the floor panel supported on the first connecting portion 71a can be lowered further than in the first stowed state. This arrangement allows the first connecting portion 71a, the second connecting portion 72b, and the fifth connecting portion 71c to occupy only a minimal amount of the height of the storage body in the second stowed state, thereby meeting the height requirements for rooftop storage and / or allowing for a more generous storage height when designing a vehicle compartment.

[0150] like Figure 4 and Figure 5Comparatively speaking, the length L1 of the storage body in the first storage state is shorter than the length L2 of the storage body in the second storage state, so the storage body occupies a smaller planar surface area in the first storage state. The height H1 of the storage body in the first storage state is higher than the height H2 of the storage body in the second storage state, making the second storage state more suitable for rooftop storage. This arrangement allows users to freely choose the storage state based on their needs and vehicle type. For example, the first storage state is more advantageous when installing the device in a car or pickup truck.

[0151] Lifting mechanism 80

[0152] like Figure 18 In this embodiment, the lifting mechanism 80 is connected between the roof 50 and the floor 60. The lifting mechanism 80 includes a drive unit 80c and four lifting devices. Of the four lifting devices, two are longitudinal lifting devices 80a connected to the longitudinal sides of the roof 50, and the other two are transverse lifting devices 80b connected to the transverse sides of the roof 50. When the vehicle house is unfolded, the two longitudinal lifting devices 80a are located outside the longitudinal side walls of the vehicle house, and the two transverse lifting devices 80b are located outside the transverse side walls of the vehicle house. The drive unit 80c can drive the lifting devices up and down. During the unfolding process of the vehicle house, the driving lifting devices drive the roof 50 to automatically Figure 19 The lower position shown is raised to Figure 18 On the contrary, when the vehicle room is stored, the driving lifting device drives the roof 50 to automatically Figure 18 The high position shown is lowered to Figure 19 The low position shown makes it easier to deploy and store the vehicle cabin.

[0153] like Figure 19 and Figure 20 , each floor panel of the floor 60 is provided with a thrust piece 66 on the outside. When the roof 50 is lowered to the lower position, it is located on the inside of the thrust piece 66 and can interfere with the thrust piece 66 in the inner and outer directions. In the embodiment shown in the figure, the thrust piece 66 is integrated into the lower guide piece 83a fixed to the outside of the floor panel. Figure 19 After the state shown, the connecting rod 50f connecting the roof panels is disconnected, and the roof 50 is leveled to the desired level under the weight of the roof 50 or with the assistance of an appropriate external force. Figure 21 In the state shown, during the leveling process, each roof panel of the roof 50 pushes the corresponding thrust member 66 (such as Figure 20, the second roof panel 54 pushes the thrust piece 66 outward in the direction of arrow B), thereby driving the floor panels of the floor 60 to move horizontally outward, or applying an appropriate external force on the floor panels to move outward, thereby separating the adjacent floor panels for subsequent stacking and storage. This design simplifies the storage operation. Figure 21 After the state shown, the adjacent floor panels are spaced a distance apart, and the floor panels of the floor 60 need to be moved horizontally inwards so that the adjacent floor panels are brought together. During the process of the floor panels being brought together horizontally, the thrust members 66 push the corresponding roof panels inwards (such as Figure 20 Thrust member 66 pushes inward in the direction of arrow A against the second roof panel 54 located inside it, thereby moving the roof panels of roof 50 horizontally closer together until the adjacent roof panels automatically rise at an angle at the joint. This design simplifies the deployment operation. The automatic angled rise design will be further described in the roof section below.

[0154] The longitudinal and transverse sides of the roof 50 are connected to the lifting device, so that the longitudinal and transverse sides of the roof 50 can be reliably supported during the extension and retraction process, so that the roof 50 can be lifted and lowered vertically and is not easy to collapse or deform, especially when the roof 50 is at an angle in both the longitudinal and transverse directions (such as Figure 18 The roof 50 forms an angle θ in the longitudinal direction and an angle γ in the transverse direction), which has a more significant effect in preventing the roof 50 from collapsing or deforming, and can also improve the ability of the vehicle-mounted house to resist external interference such as side winds.

[0155] like Figure 18 Each longitudinal lifting device 80a and transverse lifting device 80b includes an X-shaped cross arm 81. The X-shaped cross arm 81 includes two arms that intersect each other in an X-shape and are connected together at the intersection for relative rotation. Each lifting device is preferably configured as a symmetrical structure that is vertically symmetrical about the intersection of its X-shaped cross arms 81. This facilitates motion matching and reduces the risk of motion interference.

[0156] like Figure 22 、 Figure 23 or Figure 24 The longitudinal lifting device 80a and the transverse lifting device 80b each include an upper guide member 82 and two upper sliding members 84 ( Figure 22 and Figure 23 (Only one upper sliding member 84 is shown in the figure.) The upper guide member 82 may specifically be a guide rod, guide rail, guide sleeve, etc., and the upper sliding member 84 may specifically be a sliding sleeve, slider, etc. Each upper guide member 82 includes two upper guide portions 82a. The two upper sliding members 84 are respectively connected to the two upper guide portions 82a of the upper guide member 82 and can slide along the upper guide portions 82a.

[0157] The upper ends of the two arms of the X-shaped cross arm 81 are hinged to the two upper sliding members 84 respectively. Figure 22 and Figure 23 In the embodiment shown, the upper ends of the two arms of the X-shaped cross arm 81 are directly hinged to the two upper sliding members 84. Figure 24 In the illustrated embodiment, the upper ends of the two arms of the X-shaped cross arm 81 are indirectly hinged to the two upper sliding members 84 via elastic connectors 88 . The beneficial effects of the elastic connectors 88 will be described in detail later.

[0158] The two upper guide parts 82a of the upper guide member 82 are respectively connected to the two roof panels, and can be fixedly connected or hinged to the outer frame of the roof panels. If hinged, the upper guide parts 82a can rotate relative to the roof 50 during the lifting process. Figure 22 In the solution shown, a fixed connection is adopted. In this solution, the two upper guide portions 82 a are disconnected at the joints of the roof panels, thereby not affecting the stacking and storage of the roof 50 . Figure 23 In the illustrated embodiment, a hinged connection is employed. In this embodiment, the two upper guide portions 82a are connected at the joints of the roof panels by means of a sleeve portion 82b. When the roof panels are stored, the two upper guide portions 82a are disconnected at the joints of the roof panels by removing or sliding the sleeve portion 82b, thereby maintaining the stacking of the roof panels 50.

[0159] like Figure 25 , the longitudinal lifting device 80a and the transverse lifting device 80b each include a lower guide member 83 and two lower sliding members 85 ( Figure 25 Only one lower sliding member 85 is shown in the figure. The lower guide member 83 can be a guide rod, a guide rail, a guide sleeve, etc., and the lower sliding member 85 can be a sliding sleeve, a slider, etc. Each lower guide member 83 includes two lower guide portions 83a, and the two lower sliding members 85 are respectively connected to the two lower guide portions 83a of the lower guide 83 (combined with Figure 27 Understanding), it can slide along the lower guide portion 83a, and the lower ends of the two arms of the X-shaped cross arm 81 are hinged to the two lower sliding members 85 respectively.

[0160] like Figure 26 and Figure 27 The lower guide portion 83a is connected to the floor panel 60 and can be specifically arranged on the outside of the floor panel 60 and fixedly connected to the peripheral frame of the floor panel 60. The two lower guide portions 83a are disconnected at the joint between the floor panels to prevent interference with the stacking and storage of the floor panels 60. The lower guide portion 83a of the longitudinal lifting device 80a extends in the horizontal longitudinal direction to guide the lower slider 85 of the longitudinal lifting device 80a to slide in the horizontal longitudinal direction. The lower guide portion 83a of the transverse lifting device 80b extends in the horizontal transverse direction to guide the lower slider 85 of the transverse lifting device 80b to slide in the horizontal transverse direction.

[0161] like Figure 26 and Figure 27 The driving device 80c includes a power element (not shown) and four driving shafts 87. Each driving shaft 87 includes multiple driving shaft segments 87a (two in the figure). The driving shaft segments 87a are connected to form a complete driving shaft 87 at the floor joints through structures such as sliding sleeves. The four driving shafts 87 drive four lifting devices respectively. Figure 25 The lower guide portion 83a is provided as a guide sleeve, and a slot S is provided along the axial direction on the lower guide portion 83a. Figure 26 Each drive shaft 87 passes through the two lower guide portions 83a of a lower guide member 83. External threads of different rotational directions are provided on the drive shaft 87 at positions corresponding to the two lower guide portions 83a. A lower sliding member 85 is sleeved over the lower guide portions 83a. A protrusion is provided on the lower sliding member 85. This protrusion extends through an axial notch S into the lower guide portion 83a and is hingedly connected to a threaded sleeve on the external thread of the drive shaft 87 (the external thread, protrusion, and threaded sleeve are not shown). This converts the rotational motion of the drive shaft 87 into linear sliding motion of the lower sliding member 85.

[0162] When the drive shaft 87 rotates, the two lower sliding members 85 of each lifting device slide toward or away from each other, causing the upper ends of the two arms of the X-shaped cross arm 81 to rise or fall, thereby driving the roof 50 to rise or fall; after the roof 50 is raised or lowered to the target height, the drive shaft 87 stops rotating, and the drive shaft 87 and the lower sliding member 85 rely on the self-locking thread to keep the roof 50 at the target height.

[0163] like Figure 27 The four drive shafts 87 can be linked together via a transmission assembly comprising a plurality of gears 86, which can be bevel or bevel gears. Two meshing gears 86 are positioned at the ends of two adjacent drive shafts 87. This arrangement requires only a single power element to simultaneously drive the four lifting devices. This not only simplifies the structure but also facilitates the synchronization of the four lifting devices. If the four lifting devices are not aligned, the roof 50 can easily warp or become stuck during the lifting process.

[0164] Typically, the longitudinal length and transverse width of a vehicle-mounted house are not equal. In this case, to more stably support the roof 50, the longitudinal span of the X-shaped cross arm 81 of the longitudinal lifting device 80a and the transverse span of the X-shaped cross arm of the transverse lifting device 80b can be different when the vehicle-mounted house is deployed. If the longitudinal length of the vehicle-mounted house is greater than its transverse width, the longitudinal span of the X-shaped cross arm 81 of the longitudinal lifting device 80a is greater than the transverse span of the X-shaped cross arm of the transverse lifting device 80b. Conversely, the longitudinal span of the X-shaped cross arm 81 of the longitudinal lifting device 80a is smaller than the transverse span of the X-shaped cross arm of the transverse lifting device 80b. At the same time, to facilitate storage, the support arm length of the X-shaped cross arm 81 of the transverse lifting device 80b is preferably shorter than the transverse width of the vehicle-mounted house after storage. Therefore, the support arm length of the X-shaped cross arm 81 of the transverse lifting device 80a is preferably set to be shorter than the support arm length of the X-shaped cross arm 81 of the longitudinal lifting device 80b.

[0165] However, if the longitudinal span of the X-shaped cross arm 81 of the longitudinal lifting device 80a is different from the transverse span of the X-shaped cross arm of the transverse lifting device 80b, then the transmission ratio of the longitudinal and transverse drive shafts 87 is obviously not equal to 1. In addition, if the arm length of the X-shaped cross arm 81 of the transverse lifting device 80a is different from the arm length of the X-shaped cross arm 81 of the longitudinal lifting device 80b, then during the lifting process, the lifting heights of the upper ends of the arms of the longitudinal lifting device 80a and the upper ends of the arms of the transverse lifting device 80b may be easily different, thereby easily causing the roof 50 to warp and deform during the lifting process. To avoid this problem, the above-mentioned elastic connector 88 may be provided at the upper ends of the arms of the X-shaped cross arm 81, so that the upper ends of the arms of the X-shaped cross arm 81 are indirectly hinged to the upper sliding member 84 through the elastic connector 88. Specifically, the elastic connector 88 can be provided only at the upper end of the support arm of the X-shaped cross arm 81 of the horizontal lifting device 80b (illustrated solution), or the elastic connector 88 can be provided only at the upper end of the support arm of the X-shaped cross arm 81 of the longitudinal lifting device 80a, or the elastic connector 88 can be provided at the upper ends of the support arms of the X-shaped cross arms 81 of both the longitudinal lifting device 80a and the horizontal lifting device 80b.

[0166] like Figure 24 The elastic connector 88 includes an elastic portion 88b and a hinge portion 88a. The hinge portion 88a is hingedly connected to the upper sliding member 84. The hinge portion 88a is also slidably connected to the upper end of the support arm of the X-shaped cross arm 81 through the elastic portion 88b. The elastic portion 88b can be stretched or compressed along the length of the support arm, allowing the hinge portion 88a to slide or return along the length of the support arm. This can compensate for the difference in lifting height between the upper ends of the support arms of the longitudinal lifting device 80a and the transverse lifting device 80b, thereby preventing the roof from warping during the lifting process.

[0167] The elastic portion 88b can be implemented in a variety of ways. For example, one end of the upper guide portion 82a can be hinged to the roof 50, while the other end is connected to the roof 50 via an elastic member. This allows the upper guide portion 82a to deflect relative to the roof 50 during the lifting process, thereby compensating for the difference in height between the upper ends of the longitudinal and transverse lifting devices 80a and 80b. A method can also be employed to ensure that the amount of extension and compression of the elastic portion 88b along the length of the arm is similar during the lifting process. This means that the elastic portion 88b passes through the midpoint zero position when transitioning from the stretched state to the compressed state. Examples of such methods include unequal angles β between the longitudinal and transverse upper guide portions 82a, and / or unequal lengths between the longitudinal and transverse X-shaped cross arms 81. When the roof 50 remains within the elastically permissible deformation range during this transition from the stretched state to the compressed state, the elastic portion 88b effectively compensates for the difference in height between the upper ends of the longitudinal and transverse lifting devices 80a and 80b. In this case, the elastic portion 88b may not be provided.

[0168] Specifically, the upper guide member 82 of each lifting device can be arranged parallel to its lower guide member 83. Alternatively, the upper guide members 82 of some lifting devices are arranged parallel to their lower guide members 83, while the upper guide members 82 of some lifting devices are not arranged parallel to their lower guide members 83. Alternatively, the upper guide member 82 of each lifting device is not arranged parallel to its lower guide member 83.

[0169] Figure 22 In the illustrated embodiment, the upper guide member 82 is non-parallel to the lower guide member 83. The two upper guide portions 82a of the upper guide member 82 form an angle β with each other, and the two upper guide portions 82a form an angle α with the lower guide member 83. Preferably, the upper guide member 82 of at least one longitudinal lifting device 80a is non-parallel to its lower guide member 83, and the upper guide member 82 of at least one transverse lifting device 80b is non-parallel to its lower guide member 83. This design improves the vehicle house's ability to withstand both lateral and longitudinal winds, making the vehicle house more stable overall.

[0170] With the non-parallel arrangement, when the vehicle cabin is in the unfolded state, when the drive shaft 87 stops rotating, as shown in FIG. Figure 28 As shown:

[0171] For the longitudinal lifting device 80a, in the longitudinal vertical plane H passing through the axis of its upper guide member 82, its upper guide member 82 and upper sliding member 84 are respectively limited by the lower guide member 83 and the lower sliding member 85. In the longitudinal vertical plane H, the roof 50 cannot move in the A-A' direction; at the same time, since the two upper guide parts 82a of the upper guide member 82 of the longitudinal lifting device 80a form an angle β, the two upper sliding members 84 are respectively hinged on the two upper guide parts 82a that form the angle β with each other, and are in a locked state. Therefore, the roof 50 cannot move in the B-B' direction, and the roof 50 cannot deflect in the M direction in the longitudinal vertical plane H.

[0172] Similarly, for the transverse lifting device 80b, within a transverse vertical plane V passing through the axis of its upper guide member 82, its upper guide member 82 and upper sliding member 84 are respectively restrained by the lower guide member 83 and lower sliding member 85. Therefore, within the transverse vertical plane H, the roof 50 cannot move in the E-E' direction. Furthermore, because the two upper guide portions 82a of the upper guide member 82 of the transverse lifting device 80b form an angle β, the two upper sliding members 84 are hingedly connected to the two upper guide portions 82a at the angle β, thus being in a locked position. Therefore, the roof 50 cannot move in the D-D' direction.

[0173] Although the upper ends of the X-shaped cross arms 81 of the transverse lifting device 80b are provided with elastic connectors 88, which can slide relative to the X-shaped cross arms 81, the X-shaped cross arms 81 of the longitudinal lifting devices 80a on both sides prevent one of the two upper sliding members 84 of the transverse lifting device 80b from sliding downward in the C direction and the other from sliding upward in the C' direction (and vice versa), thus preventing the roof 50 from deflecting in the N direction.

[0174] Therefore, by adopting the above-mentioned non-parallel setting scheme, the roof 50 cannot produce horizontal movement, vertical movement, or deflection in the longitudinal vertical plane H and the transverse vertical plane V. Therefore, when raising and lowering the roof 50, no additional limiting mechanism is required, and the roof 50 can be raised and lowered vertically relative to the floor 60. Moreover, after being deployed, the vehicle-mounted house has a strong ability to resist external interference such as side wind, so it is highly stable.

[0175] Figure 23 In the illustrated embodiment, the upper guide 82 is arranged parallel to the lower guide 83, and both upper guide portions 82a of the upper guide 82 are parallel to the lower guide 83. The parallel arrangement makes motion matching easier and motion interference is less likely to occur.

[0176] Specifically, such as Figure 29The X-shaped cross arm 81 comprises two arms that intersect to form an X-shape and are hinged together at the intersection via a hinged structure. Each arm comprises two segments. In the illustrated embodiment, one arm (hereinafter referred to as the first arm) comprises a first segment 81a and a fourth segment 81d, while the other arm (hereinafter referred to as the second arm) comprises a second segment 81b and a third segment 81c. The first segment 81a and the second segment 81b are connected to the roof 50, while the third segment 81c and the fourth segment 81d are connected to the floor 60.

[0177] The two sections of each arm can be connected together detachably, that is, the two sections of each arm can be connected together or separated. With this design, the two sections of each arm can be stacked and stored together with other components of the vehicle house (roof 50, floor 60, etc.), so that the vehicle house as a whole can be automatically Figure 19 The state shown is folded along the seam of the roof panel to Figure 4 or Figure 5 The state shown in FIG. 8 is not required to remove the X-shaped cross arm 81 separately for storage, making the storage and deployment of the vehicle-mounted room more convenient and quick. The method of separating the two arm sections for storage and connecting them for lifting is not limited to the embodiment shown in FIG.

[0178] Specifically, the two arm sections of each arm can be directly plugged together or indirectly plugged together through a transition piece. In the illustrated embodiment, a first transition piece 81e and a second transition piece 81f are provided. The first arm section 81a and the fourth arm section 81d are plugged together through the first transition piece 81e, and the second arm section 81b and the third arm section 81c are plugged together through the second transition piece 81f.

[0179] Specifically, such as Figures 29-32 、 Figure 33-Figure 35 , the connection position of the two arm sections of each arm can be located at the intersection of the two arms. Or, Figure 36-Figure 38 The connection position of the two arm sections of each arm can also be staggered with the intersection position of the two arms.

[0180] Specifically, Figures 29-32 、 Figure 33-Figure 35 In the illustrated embodiment, the hinge structure includes a first hinge portion 81g, a second hinge portion 81h and a hinge shaft (not shown in the figure).

[0181] The first arm segment 81a of the first arm connected to the roof 50 and the third arm segment 81c of the second arm connected to the floor 60 are hinged together through a first hinge portion 81g; the second arm segment 81b of the second arm connected to the roof 50 and the fourth arm segment 81d of the first arm connected to the floor 60 are hinged together through a second hinge portion 81h. Figure 23When the two arm segments of the first arm (the first arm segment 81a and the fourth arm segment 81d) are separated and the two arm segments of the second arm (the second arm segment 81b and the third arm segment 81c) are separated, the first arm segment 81a of the first arm connected to the roof 50 is still hinged to the third arm segment 81c of the second arm connected to the floor 60, and the fourth arm segment 81d of the first arm connected to the floor 60 is still hinged to the second arm segment 81b of the second arm connected to the roof 50. This makes it convenient to store the vehicles and can generate a pulling force on the roof 50 and the floor 60. The pulling force can help the stacked vehicles to maintain their stacked shape and not easily fall apart.

[0182] After the four arm segments are connected, the first arm segment 81a and the fourth arm segment 81d are in a straight line, and the second arm segment 81b and the third arm segment 81c are in a straight line. At the same time, the first arm segment 81a and the third arm segment 81c are hinged via the first hinge portion 81g, and the second arm segment 81b and the fourth arm segment 81d are hinged via the second hinge portion 81h. After the two arms are hinged, the hinge axis of the first hinge portion 81g, the hinge axis of the second hinge portion 81d, and the axis of the hinge shaft coincide (see Figure 29 Middle L).

[0183] Figure 32 This figure illustrates a hinge structure. In this embodiment, the first hinge portion 81g includes a first guide slot M1 and a first slider N1. The first guide slot M1 is provided on the first arm segment 81a, and the first slider N1 is provided on the third arm segment 81c. The first guide slot M1 cooperates with the first slider N1 to guide the first slider N1 along a predetermined trajectory around the hinge axis of the first hinge portion 81g, thereby hingedly connecting the first arm segment 81a and the third arm segment 81c.

[0184] Similarly, the second hinge portion 81h includes a second guide slot M2 and a second slider N2. The second guide slot M2 is provided on the fourth arm segment 81d, and the second slider N2 is provided on the second arm segment 81b. The second guide slot M2 cooperates with the second slider N2 to guide the second slider N2 along a predetermined trajectory around the hinge axis of the second hinge portion 81h, thereby hingedly connecting the second arm segment 81b and the fourth arm segment 81d.

[0185] An escape space is reserved between the first guide groove M1 and the second guide groove M2 for the hinge shaft to pass through. The hinge shaft passes through the first transition piece 81e, the escape space and the second transition piece 81f in sequence, thereby hingedly connecting the two arms together.

[0186] Ports Mk may be provided at the ends of the first guide groove M1 and the second guide groove M2. When the hinge axis of the first hinge part 81g coincides with the hinge axis of the second hinge part 81d, the port of the first guide groove M1 is opposite to the port of the second guide groove M2, so that the first slider N1 can slide from the first guide groove M1 into the second guide groove M2 through the port. Similarly, the second slider N2 can slide from the second guide groove M2 into the first guide groove M1 through the port. This design can ensure that the two arms can swing relative to each other at a large angle.

[0187] The guide groove and slider can be positioned along the hinge axis to maintain a fixed relative position between them. In the illustrated scheme, the guide groove is a T-shaped groove structure, and the slider is a T-shaped block. The guide groove and slider utilize the large end of the "T" to achieve a positional fit. Of course, the method for achieving positional fit is not limited to this. For example, the guide groove can be configured as a dovetail or L-shaped groove in cross section, and the slider can be configured as a dovetail block or L-shaped block to achieve positional fit between the two.

[0188] Figure 32 The hinge structure shown has high reliability, and the concave-convex fit between the guide groove and the slider can increase the structural strength of the support arm to a certain extent.

[0189] Figure 35 Another structure of the hinge part is shown. In this embodiment, the hinge part includes two orifice plates N3 and a hollow shaft N4.

[0190] The two orifice plates N3 of the first hinged portion 81g are respectively arranged on the first arm segment 81a and the third arm segment 81c and avoid the sockets on the arm segments for inserting transition pieces. The two ends of the hollow shaft N4 are respectively inserted into or aligned with the orifices of the two orifice plates N3, thereby hingedly connecting the first arm segment 81a and the third arm segment 81c together.

[0191] The two orifice plates N3 of the second hinged portion 81h are respectively arranged on the second arm segment 81b and the fourth arm segment 81d and avoid the sockets on the arm segments for inserting transition pieces. The two ends of the hollow shaft N4 are respectively inserted into or aligned with the orifices of the two orifice plates N3, thereby hingedly connecting the first arm segment 81a and the third arm segment 81c together.

[0192] The hinge shaft passes through the hollow shaft hole of the first hinge part 81g, the first transition piece 81e, the second transition piece 81f and the hollow shaft hole of the second hinge part 81h in sequence, thereby hingedly connecting the two arms together.

[0193] Figure 32 and Figure 35In the two embodiments, if a connecting piece (such as a bolt, etc.) is provided to connect the first transition piece 81e and the second transition piece 81f, and the connecting piece passes through the hinged parts on the four arm segments of the X-cross arm to make them hinged, the structural stability of the X-cross arm during the lifting process will be significantly enhanced.

[0194] Of course, the structure of the hinge is not limited to Figure 32 and Figure 35 In the two embodiments, any structure is acceptable as long as it can achieve the connection of the two arm segments and ensure that the two arm segments can rotate relative to each other after the connection.

[0195] Rooftop 50

[0196] like Figure 21 In this embodiment, the roof includes a first roof panel 51, a second roof panel 52, a third roof panel 53, and a fourth roof panel 54. The first roof panel 51 and the second roof panel 52 are adjacent, the second roof panel 52 and the fourth roof panel 54 are adjacent, the fourth roof panel 54 and the third roof panel 53 are adjacent, and the first roof panel 51 and the third roof panel 53 are adjacent, forming joints between the adjacent roof panels.

[0197] Figure 39 for Figure 21 The enlarged view of part A in the figure is as follows: Figure 39 A guide pair is provided at the joint of the roof panels, and the guide pair includes a guiding portion 50a and a guided portion 50b. Figure 40 is the end view of the joint, that is, the perspective from one end of the joint to the joint, such as Figure 40 The joints of the roof panels are further provided with a plug-in pair, which includes a plug-in recess 50c and a plug-in protrusion 50d. A plug-in pair can be provided at intervals along the length direction of the joint.

[0198] During the deployment of the vehicle room, Figure 21 After reaching the state shown, the roof panels need to be moved closer to each other in the horizontal direction. Figure 40 The first roof panel 51 and the second roof panel 52 are shown as an example to illustrate the operation process of the guide pair and the plug-in pair at the joint between the two when the two are horizontally approaching. It should be understood that the operation process of the guide pair and the plug-in pair at the joints of other roof panels is the same: after the first roof panel 51 and the second roof panel 52 are horizontally approached to each other until the guiding portion 50a and the guided portion 50b are in contact with each other, and then they are further approached, the guided portion 50b will be guided by the guide portion 50a along the joint. Figure 40The direction indicated by the middle arrow A is tilted upward, so that the side of the entire second roof panel 52 near the joint is tilted upward. At the same time, the plug-in protrusion 50d is gradually inserted into the plug-in recess 50c. Under the mutual restraint of the plug-in protrusion 50d and the plug-in recess 50c, the side of the first roof panel 51 near the joint is also tilted upward along with the side of the second roof panel 52 near the joint, so that the first roof panel 51 and the second roof panel 52 automatically bulge at the joint; when the first roof panel 51 and the second roof panel 52 are close to the extreme position, the first roof panel 51 and the second roof panel 52 form a preset angle (such as Figure 41 ), and the insertion protrusion 50d is substantially fully inserted into the insertion recess 50c and locked with a locking member deep within the recess 50c, locking the first roof panel 51 and the second roof panel 52 together. At this point, the connecting rod 50f between the roof panels 50 can be rotated and connected, forming a bottom connection between the roof panels at the preset angle. The connecting rod 50f and the roof panels at the preset angle form a stable triangular structure, ensuring the stability of the roof and maintaining the preset angle during the raising and lowering of the roof panels 50.

[0199] As described above (in the second paragraph of the lifting mechanism section), the vehicle-mounted room is unfolded to Figure 21 After the state shown, adjacent floor panels are spaced a distance apart, and the floor panels of the floor 60 need to be moved horizontally inwards so that the adjacent floor panels can be brought together. Figure 20 Since each floor panel of the floor 60 is provided with a thrust piece 66 on the outside, and the roof panel at the lower position is located on the inside of the thrust piece 66, when the floor panels are horizontally close to each other, the thrust piece 66 pushes the corresponding roof panel inward (such as Figure 20 , the thrust member 66 pushes the second roof panel 54 inwardly along the direction of arrow A, thereby driving the roof panels of the roof 50 to move horizontally closer. In other words, the floor panels move horizontally closer together with the thrust member 66. Figure 21 In the illustrated state, the spacing between adjacent floor panels is preferably no less than the spacing between adjacent roof panels. This ensures that the adjacent roof panels form a predetermined angle at their joints before or simultaneously with the floor panels closing together, thus avoiding the situation where the floor panels have already closed but the roof panels have not yet formed the predetermined angle. As can be seen from the above description, the provision of the thrust member 66 simplifies the stowage and deployment operations, making the vehicle cabin more convenient to unfold. Furthermore, the thrust member 66 also serves to limit the roof when it is lowered.

[0200] When the adjacent roof panels form a preset angle, the guided portion 50b at least partially extends above the joint of the two adjacent roof panels and above the roof panel provided with the guide portion 50a. Figure 41 understand, Figure 41 In the figure, the adjacent first and second roof panels 51 and 52 are at a predetermined angle, with a portion of the guided portion 50b on the second roof panel 52 extending above the joint between the two panels and above the first roof panel 51. This design allows the guided portion 50b to shield the joint between the adjacent roof panels, providing protection from wind and rain. Furthermore, as shown in the figure, if the portion of the guided portion 50b extending above the joint is angled, it can also serve as a diversion device, directing rainwater down the roof rather than accumulating on it.

[0201] In addition, if Figure 40 The roof panel with the guided portion 50b may further be provided with a socket portion 50e for socketing the guiding portion 50a of the adjacent roof panel. Figure 41 When adjacent roof panels are positioned at a predetermined angle, the inner surface of the socket portion 50e and the outer surface of the guide portion 50a inserted therein are in close contact, with waterproof material sandwiched between them, thereby sealing the seam between the adjacent roof panels. Preferably, the cross-sectional shape of the inner surface of the socket portion 50e and the cross-sectional shape of the outer surface of the guide portion 50a are both arcuate. This provides a better sealing effect when the two contact each other, and reduces friction when the guided portion 50b slides on the surface of the guide portion 50a, resulting in smoother sliding. Furthermore, after the roof 50 is raised and reaches the predetermined angle, the forces between the roof panels are balanced, resulting in a stable structure. Of course, this is not limited to arcuate shapes; other shapes are also possible.

[0202] In addition, in order to further reduce the friction between the guided portion 50b and the guiding portion 50a, the portion where the guided portion 50b contacts the guiding portion 50a can be configured as a circular roller, as shown in the illustrated solution. This allows the roof panels to further bulge by rotating together around the axis of the circular roller until a preset angle is reached (the same applies to the roof leveling process and vice versa).

[0203] A plurality of roof panels with joints intersecting at one point constitute a set of roof panel components. In the illustrated solution, four roof panels constitute a set of roof panel components. Figure 42 When the adjacent roof panels form a preset angle, the guided portions 50b of the roof panel components are stacked up and down at the intersection of the seams. Figure 42In this design, the guided portion 5b of the second roof panel 52 and the guided portion 50b of the third roof panel 53 are stacked on the lower layer, while the two guided portions 50b of the first roof panel 52 are stacked on the upper layer, shielding a portion of the guided portion 5b of the second roof panel 52 and a portion of the guided portion 50b of the third roof panel 53. This design ensures a tight seal at the joint intersection, preventing rainwater from seeping into the room through the joint intersection. Furthermore, a flexible member can be placed between the joints to further enhance the seal.

[0204] Side wall (10-40), side wall extension and retraction mechanism 110 and side door 120

[0205] like Figure 1 In this embodiment, the vehicle room is provided with four side walls, namely a front side wall 10, a rear side wall 20, a left side wall 30 and a right side wall 40.

[0206] like Figure 43 At least one side wall is formed by joining two or more side wall units parallel to the side wall. In the illustrated embodiment, the front side wall 10 is formed by joining the first and second side wall units Q1 and Q2 in the left-right direction. The rear side wall 20 is formed by joining the third and fourth side wall units Q3 and Q4 in the left-right direction. The left side wall 30 is formed by joining the fifth and sixth side wall units Q5 and Q6 in the front-to-back direction. The right side wall 40 is formed by joining the seventh and eighth side wall units Q7 and Q8 in the front-to-back direction.

[0207] The number of side wall units in each side wall is equal to the number of floor panels joined in a direction parallel to the side wall. In the figure, the number of side wall units in the front side wall 10 (two) or the rear side wall 20 (two) is equal to the number of floor panels joined in the front-to-back direction (two), and the number of side wall units in the left side wall 30 (two) or the right side wall 40 (two) is equal to the number of floor panels joined in the left-to-right direction (two).

[0208] The first side wall unit Q1 and the fifth side wall unit Q5 are connected to the front and left frame edges of the second floor panel 62. When stored, these two side wall units are stacked successively above the second floor panel 62. The second side wall unit Q2 and the seventh side wall unit Q7 are connected to the front and right frame edges of the first floor panel 61. When stored, these two side wall units are stacked successively above the first floor panel 61. The third side wall unit Q3 and the sixth side wall unit Q6 are connected to the left and rear frame edges of the fourth floor panel 64. When stored, these two side wall units are stacked successively above the fourth floor panel 64. The fourth side wall unit Q4 and the eighth side wall unit Q8 are connected to the right and rear frame edges of the third floor panel 63. When stored, these two side wall units are stacked successively above the third floor panel 63.

[0209] like Figure 43 , at least one side wall unit includes an upper wall X1 and a lower wall X2. The upper wall X1 is connected to the lower wall X2 and can slide up and down relative to the lower wall X2. After sliding to the target height position, it is locked using a locking structure such as a socket or a latch. The locking structure can be set at multiple different height positions, so that the upper wall X1 can be locked at different height positions. In the illustrated scheme, the eight side wall units are designed to include an upper wall X1 and a lower wall X2. With this structure, after the car-mounted room is unfolded, the user can flexibly adjust the position of the upper wall X1 according to needs. For example, the upper wall X1 can be slid upward to a position in contact with the roof (i.e. Figure 1 As shown in the state), as a house structure, the upper wall X1 can also be slid downward to a position a distance away from the roof 50 (i.e. Figure 2 As shown in the state), as a fence structure, so that smooth ventilation and a transparent view can be obtained.

[0210] The upper wall X1 of the mutually spliced ​​side wall units can slide up and down individually or synchronously. For example, the upper wall of the first side wall unit Q1 and the upper wall of the second side wall unit Q2 can slide up and down individually, or they can be connected together with connecting pins or other connecting structures so that they can slide up and down synchronously.

[0211] like Figure 44 , a door opening is provided on at least one side wall and a side door 120 is hinged. In the illustrated scheme, the side door is hinged to the eighth side wall unit Q8. The side door 120 includes an upper door body 1201 and a lower door body 1202. The upper door body 1201 is connected to the lower door body 1202 and can slide up and down relative to the lower door body 1202. After sliding to the target position, it is locked using a locking structure such as a socket or a latch. The locking structure can be provided at multiple different height positions, so that the upper door body 1201 can be locked at different height positions. With this structure, the user can slide the upper door body 1201 downward to a position a distance away from the roof 50 to enhance ventilation in the room. At the same time, the lower door body 1202 ensures safety (prevents falling from the roof) and privacy. The upper door body 1201 and the upper wall X1 can slide independently. For example, the upper wall X1 can be slid upward to a position in contact with the roof, and only the upper door body 1201 can be slid downward to a position a distance away from the roof 50. As Figure 49 The upper door body 1201 is provided with an upper hinge shaft 1203 on the side frame side, and the eighth side wall unit Q8 is provided with a hinge sleeve on the side frame side. The hinge sleeve is sleeved on the outer surface of the upper hinge shaft 1203. The upper hinge shaft 1203 can slide up and down in the sleeve and rotate around its own axis, so that the upper door body 1201 can both rotate and slide up and down. Figure 50The side frame edge of the lower door body 1202 is hinged to the lower wall X2 of the eighth side wall unit Q8 through the lower hinge shaft 1204 and limited up and down, serving as the lower end rotation axis of the lower door body 1202, so that the lower door body 1202 can rotate but cannot move up and down.

[0212] like Figure 45 and Figure 46 The side frame edges of the upper wall X1 and the lower wall X2 are provided with long grooves W and long ridges V. The long ridges V are inserted into the long grooves W along the length direction of the long grooves W. When the upper wall X1 slides up and down, the long ridges V slide up and down in the long grooves W. With this design, the upper wall X1 and the lower wall X2 use their own side frame edges to achieve a sliding guide connection without the need for an additional guide connection structure. Similarly, Figure 49 The side frame edges of the upper door body 1201 and the side frame edges of the lower door body 1202 are provided with long chute grooves W and long ridges V. The long ridges V are inserted into the long chute grooves W along their length. When the upper wall body X1 slides up and down, the long ridges V slide up and down within the long chute grooves W. This design allows the upper door body 1201 and the lower door body 1202 to achieve a sliding guide connection using their own side frame edges, without the need for an additional guide connection structure. Furthermore, the long chute grooves W and long ridges V can also reduce the risk of air and rain leakage at the seams of the side walls and at the seams between the side door and the side wall. The long chute grooves W and long ridges V can be configured in a variety of ways, not limited to the one shown in the figure.

[0213] like Figure 47 At least one lower wall X2 includes an upper wall portion X21 and a lower wall portion X22. The lower wall portion X22 is offset outward from the upper wall portion X21 by a distance, thereby forming a first storage space X3 outside the upper wall portion X21 and above the lower wall portion X22 for accommodating the upper wall portion X1 after it slides down. A second storage space X4 is formed below the upper wall portion X21 and inside the lower wall portion X22 for accommodating the vehicle compartment's facility components 90. This design improves the space utilization of the vehicle compartment storage unit and enhances the structural strength of the lower wall X2. In the illustrated embodiment, this design is used for the lower wall X2 of the front side wall 10 and the lower wall X2 of the rear side wall 20.

[0214] like Figure 48 The bottom of the side wall (that is, the bottom of each side wall unit) is hinged to the floor. In the illustrated embodiment, a hinge axis Y is provided at the bottom of the side wall, parallel to the floor. A clamping sleeve 67 is provided on the edge of the floor frame. The clamping sleeve 67 is inserted outside the hinge axis Y, thereby achieving the hinged connection between the side wall and the floor. The side wall is deployed and retracted by rotating relative to the floor. When deployed, the side wall is roughly perpendicular to the floor. When retracted, the side wall is stacked above the floor and is roughly parallel to the floor.

[0215] like Figure 45 and Figure 46, a stopper U is provided on the side frame of the side wall. When the vehicle room is unfolded, the two side wall units spliced ​​together (which can be the side wall units of the same side wall, such as Figure 45 Q5 and Q6 in the figure can also be side wall units with different side walls, such as Figure 46 The stoppers U of Q3 and Q6) overlap each other and stop each other in the inner and outer directions perpendicular to the two side wall units, for example, Figure 46 In the figure, a stopper U of the third side wall unit Q3 and a stopper U of the sixth side wall unit Q6 stop each other in the inner and outer directions perpendicular to the third side wall unit Q3. At the same time, another stopper U of the third side wall unit Q3 and another stopper U of the sixth side wall unit Q6 stop each other in the inner and outer directions perpendicular to the sixth side wall unit Q6.

[0216] The stopper U can play a role of stopping and reinforcing, so that the two side walls spliced ​​together can be plugged into each other and stopped to connect after the floor is closed, and can make the two side wall planes rotate from inside to outside relative to the floor at the same time (for example Figure 45 Q5 and Q6 in the figure), and after reaching a certain position (roughly perpendicular to the floor), they stop each other and cannot continue to rotate outwards, and also make the corner splicing of the two side walls that are spliced ​​and angled with each other (such as Figure 46 Q6 and Q3) in the middle cannot be further turned inward (locked by a latch that does not disengage, the latch is not shown) or rotated outward in both the inner and outer directions, and together with the floor, they form a stable three-dimensional structure; in addition, they also play a sealing role, which can reduce the risk of wind and rain leakage at the joints of the two side walls to a certain extent. When the eight side walls are rotated from the inside to the outside (roughly perpendicular to the position of the floor), the four corners of the two side walls that are spliced ​​and angled with each other (Q1-Q5, The stoppers U on the eight side walls (Q6-Q3, Q4-Q8, Q7-Q2) are plugged into each other to stop them, so that all eight side walls cannot continue to rotate inward or outward. For example, if the upper and lower wall X1 and X2 frame beams at the joints of the side wall plane splicing pairs (Q2-Q1, Q5-Q6, Q3-Q4, Q8-Q7) are equipped with pins (not shown) to slidably connect the side wall plane splicing pairs, it can further ensure that the side wall plane splicing pairs (Q2-Q1, Q5-Q6, Q3-Q4, Q8-Q7) are coplanar. At the same time, after all eight side walls are rotated and spliced ​​into place, the stoppers U not only allow any upper wall X1 of the eight side walls to slide up and down on the basis of the lower wall X2, but also, after sliding up and down, the stoppers U of the upper wall X1 and the lower wall X2, as well as the stoppers U between the two side wall splicing pairs, remain plugged in and stopped. The stopper U may be provided in a variety of configurations and is not limited to the configuration shown in the figure.

[0217] like Figure 48Two adjacent side walls at an angle to each other have different heights relative to the floor's rotation axis. For example, in the figure, the sixth side wall unit Q6 and the third side wall unit Q3 have rotation axes R1 and R2, respectively, with R1 being higher than R2. This design allows the sixth side wall unit Q6 and the third side wall unit Q3 to be stacked parallel to each other above the fourth floor panel 64. A gap exists between the level where the sixth side wall unit Q6 resides and the level where the third side wall unit Q3 resides, providing space for stacking facility components.

[0218] like Figure 49 An open slide groove G is provided on the frame of the upper wall X1, so that when the side wall needs support, the T-shaped sliding connection part of the oblique support rod 102b (the oblique support rod 102b is on one side shown in the figure, and the other side in the figure can be set similarly) can be inserted into the frame of the upper wall X1 on the side wall through the opening of the open slide groove G, so that the upper wall X1 can slide up and down on the basis of the lower wall X2, and be supported and stabilized by the oblique support rod 102b, and this insertion connection can be realized on the ground.

[0219] like Figure 51-53 The two side walls are adjacent to each other and form an angle with each other. One is connected to the roof 50 of the vehicle room and is extended and retracted under the drive of the lifting mechanism 80. The other is connected to the side wall extension and retraction mechanism 110 and is extended and retracted under the drive of the side wall extension and retraction mechanism 110. In the illustrated scheme, the fifth side wall unit Q5, the sixth side wall unit Q6, the seventh side wall unit Q7, and the eighth side wall unit Q8 are connected to the roof 50. Specifically, Figure 52 , connected to the roof 50 by connecting rod Z, as shown Figure 46 The connecting rod Z is connected to the lower wall X2 and does not affect the upward and downward sliding of the upper wall X1. In the illustrated embodiment, the first side wall unit Q1 is connected to one set of side wall extension and retraction components of the side wall extension and retraction mechanism 110, and the third side wall unit Q3 is connected to another set of side wall extension and retraction components of the side wall extension and retraction mechanism 110.

[0220] When unfolding, the lifting mechanism 80 is first used to drive the roof 50 to rise, driving the fifth side wall unit Q5, the sixth side wall unit Q6, the seventh side wall unit Q7, and the eighth side wall unit Q8 to rotate from the inside to the outside relative to the floor 60. Since the stopper U of the fifth side wall unit Q5 and the stopper U of the sixth side wall unit Q6 overlap with each other, and the stopper U of the seventh side wall unit Q7 and the stopper U of the eighth side wall unit Q8 overlap with each other, they can rotate outward together with the second side wall unit Q2 and the fourth side wall unit Q4. Then, the side wall unfolding and retracting mechanism 110 is used to drive the first side wall unit Q1 and the third side wall unit Q3 to rotate from the inside to the outside. Since the stopper U of the second side wall unit Q2 and the stopper U of the first side wall unit Q1 overlap with each other, and the stopper U of the fourth side wall unit Q4 overlaps with the stopper U of the second side wall unit Q2, they can rotate outward together with the second side wall unit Q2 and the fourth side wall unit Q4.

[0221] Specifically, such as Figure 53 and Figure 54 The side wall deployment and retraction assembly includes a rotating member 1101, a moving member 1102 and a top support member 1103. The moving member 1102 cooperates with the rotating member 1101 and can move along the rotation axis of the rotating member 1101 as the rotating member 1101 rotates. The top end of the top support member 1103 is connected to the corresponding side wall, and the bottom end of the top support member 1103 is connected to the moving member 1102. The top support member 1103 can swing with the movement of the moving member 1102, thereby driving the front side wall 10 and the rear side wall 20 to rotate relative to the floor 60, thereby realizing deployment and storage.

[0222] In the illustrated embodiment, the rotating member 1101 is a screw, and the movable member 1102 comprises two sleeves: one sleeve fits over the screw and engages with its threads, while the other sleeve fits over a guide shaft 1105, which is parallel to the screw and engages with the guide shaft. A connecting post is positioned between the two sleeves, and a fork is formed at the bottom end of the top support member 1103, which protrudes beyond the connecting post. This allows the bottom end of the top support member 1103 to be easily disconnected from the movable member 1102 after the vehicle cabin is deployed (the top end of the top support member 1103 can be similarly positioned with the side walls 10 and 20). The top support member 1103 can then be adjusted to rest against the side wall or removed directly to prevent it from interfering with the space inside the cabin. Each of the two sleeves can be provided with a connector, which can be positioned on two interlocking floor panels. When the two floor panels are joined, the connectors on the two sleeves interlock to form the connecting post.

[0223] In addition, if Figure 53 and Figure 55When the vehicle-mounted room is in the unfolded state, the side wall deployment assembly is located on the inner side of the side wall. The side wall deployment mechanism also includes a driving rod 1104. One end of the driving rod 1104 extends to the outside of the side wall and is connected to the power element, and the other end extends to the inside of the side wall and is connected to the rotating part 1101 of the side wall deployment assembly, thereby transmitting power to the rotating part 1101.

[0224] Specifically, a driving rod 1104 can drive only the rotating parts 1101 of one set of side wall deployment and retraction components, or it can drive the rotating parts 1101 of multiple sets of side wall deployment and retraction components at the same time. In the illustrated scheme, the sliding part 701 of the floor deployment and retraction mechanism 70 for driving the floor panels to slide is provided with a through hole for the driving rod 1104 to pass through. The driving rod 1104 passes through the through hole and is connected to the rotating parts 1101 of two sets of side wall deployment and retraction components at the same time to drive both of them at the same time.

[0225] Support mechanism 100

[0226] like Figure 1 The support mechanism 100 includes a ground support device 101 and a side wall support device 102. The top of the ground support device 101 is connected to the floor 60 and / or the floor unfolding and retracting mechanism 70 of the vehicle room. When the vehicle room is unfolded, the ground support device 101 is located below the floor 60, and the bottom end of the ground support device 101 is supported on the ground. The bottom end of the side wall support device 102 is connected to the floor 60 and / or the floor unfolding and retracting mechanism 70 of the vehicle room. When the vehicle room is unfolded, the side wall support device 102 is located outside the side wall, and the top end of the side wall support device 102 is connected to the side wall. With this design, the vehicle room is stable as a whole when it is unfolded, is not easy to shake or deform, and can withstand higher levels of wind.

[0227] The top end of the floor support device 101 and the bottom end of the side wall support device 102 are movably connected to the floor 60 and / or the floor unfolding and retracting mechanism 70, and can be rotated to a horizontal state (i.e., a state parallel to the floor 60) while remaining connected to the floor 60 and / or the floor unfolding and retracting mechanism 70, so that they can be stacked and stored together with the floor 60, roof 50, side walls, floor unfolding and retracting mechanism 70, etc., without the need to be disassembled for separate storage. Therefore, the storage and deployment operations of the vehicle room are simpler and faster, and after storage, there are fewer scattered parts and the integrity is good.

[0228] like Figure 1 or Figure 17 The ground support device 101 includes a main support leg 101a. In the illustrated scheme, six main support legs 101a are provided. The six main support legs 101a are vertically supported on the ground. Every two main support legs 101a are arranged in a row along the left-right direction, and the six main support legs 101a are arranged in three rows in sequence along the front-back direction.

[0229] like Figure 1 or Figure 17 The top of the main leg 101a is connected to a slide rod 101d. The slide rod 101d is inserted into the sleeve of the floor extension and retraction mechanism 70 in the left and right directions and can slide along the sleeve and slide into the sleeve. In the illustrated embodiment, the top of the three rows of main legs 101a are respectively inserted into the first sleeve 71d, the second sleeve 71e, and the third sleeve 71f through a set of slide rods 101d. The top of the main leg 101a is rotatably connected to the slide rod 101d and can be rotated to a state that is colinear with the slide rod 101d ( Figure 17 In this manner, as the slide bar 101d slides into the sleeve, it also drives the main leg 101a to slide back into the sleeve, thereby reducing the floor space and height of the vehicle housing when it is folded. Due to the limited length of the sleeve, to accommodate as much of the main leg 101a and slide bar 101d as possible within the sleeve, the right end of the left slide bar 101d and the left end of the right slide bar 101d can be interlocked within the sleeve, or the slide bar 101d can be designed as a telescopic rod.

[0230] like Figure 1 or Figure 17 The ground support device 101 further includes a first auxiliary support leg 101 b , which can further enhance the support stability of the ground support device 101 .

[0231] In the deployed state, the first auxiliary leg 101b is positioned between the two main legs 101a, spaced apart in the front-to-back direction. The bottom end of the first auxiliary leg 101b is supported on the ground or connected to the main leg 101a via a connector (not shown), allowing for adjustable tilt. The top end of the first auxiliary leg 101b is pivotally and slidingly connected to the left or right edge of the floor panel. The bottom end of the first auxiliary leg 101b is tilted forward or backward relative to the top end, enhancing support stability. In the illustrated embodiment, a total of four first auxiliary legs 101b are provided: one is located between the main leg 101a at the left front position and the main leg 101a at the left center position, with its top end connected to the left frame edge of the second floor panel 62; one is located between the main leg 101a at the left center position and the main leg 101a at the left rear position, with its top end connected to the left frame edge of the fourth floor panel 64; one is located between the main leg 101a at the right front position and the main leg 101a at the right center position, with its top end connected to the right frame edge of the first floor panel 61; and one is located between the main leg 101a at the right center position and the main leg 101a at the right rear position, with its top end connected to the right frame edge of the third floor panel 63.

[0232] When storing, rotate the first auxiliary leg 101b to a position parallel to the frame edge of the connected floor panel ( Figure 17Then, slide the first auxiliary leg 101b forward or backward until the front end of the first auxiliary leg 101b does not exceed the front side frame edge of the connected floor panel, and the rear end does not exceed the rear side frame edge of the connected floor panel ( Figure 57 As shown in the state, the first auxiliary leg 101b can be stacked and stored together with the floor panel 60, and after storage, it is on the same layer as the floor panel so that the height after storage will not be increased.

[0233] like Figure 1 or Figure 17 The ground support device 101 further includes a second auxiliary support leg 101c. The provision of the second auxiliary support leg 101c can further enhance the support stability of the ground support device 101.

[0234] In the deployed state, the second auxiliary leg 101c is positioned between the two main legs 101a, spaced apart in the left-right direction. The bottom end of the second auxiliary leg 101c is supported on the ground or connected to the main leg 101a via a connector (not shown), allowing for adjustable tilt. The top end of the second auxiliary leg 101c is pivotally connected to the sleeve of the floor deployment mechanism 70. The bottom end of the second auxiliary leg 101c is tilted left or right relative to the top end. This tilted design further enhances support stability. In the illustrated embodiment, two second auxiliary legs 101c are provided, each pivotally connected to the first sleeve 71d.

[0235] When storing, if Figure 9 , rotate the second auxiliary support leg 101c and rotate it into the space enclosed by the first sleeve 71d and the sliding members 701 at both ends of the first sleeve 71d. With this design, the height and plane area of ​​the vehicle room after storage are smaller.

[0236] After setting the second auxiliary support leg 101c, the car house can remain stable even after the vehicle is driven out from under the floor of the car house (that is, after the car house is no longer supported by the roof). Therefore, after the car house is unfolded, the user can choose to drive the vehicle out from under the car house according to needs. In order to avoid interference, the second auxiliary support leg 101c can be unfolded and supported on the ground after the vehicle is driven out. The second auxiliary support leg 101c can be disabled before the vehicle is driven out.

[0237] like Figure 57The floor support device 101 also includes a limiting support member 101e. In the deployed state, one end of the limiting support member 101e is rotatably connected to the sliding member 701 of the floor deployment mechanism, which slides in the front-to-back direction. The other end of the limiting support member 101e is detachably connected to the sliding rod 101d. In the illustrated embodiment, two limiting support members 101e are provided. The front ends of the two limiting support members 101e are respectively connected to the two sliding members 701 of the floor deployment mechanism 70, which slide in the front-to-back direction. The rear ends of the two limiting support members 101e are respectively connected to the rear sliding rod 101d. The limiting support members 101e limit the sliding movement of the sliding rod 101d and support the sliding rod 101d, further improving the support stability of the floor support device 101. The limiting support members 101e can also transfer the load on the floor to the ground.

[0238] When storing, if Figure 9 , release the connection between the limiting support member 101e and the sliding rod 101d, and then rotate the limiting support member 101e to a state parallel to the connected sliding member 701, so that the limiting support member 101e can be stacked and stored together with the floor unfolding and retracting mechanism 70.

[0239] like Figure 17 , the ground support device 101 also includes an auxiliary support member 101f, one end of the auxiliary support member 101f is rotatably connected to the sleeve, and the other end is detachably connected to the main support leg 101a. In the illustrated scheme, two auxiliary support members 101f are provided, and the top ends of the two auxiliary support members 101f are respectively connected to the sleeve on the rear side (the second sleeve 71e), and the bottom ends of the two auxiliary support members 101f are respectively connected to the two main support legs 101a in the rear row. The provision of the auxiliary support members 101f can further enhance the support stability of the ground support device 101. Similarly, a similar arrangement can also be adopted on the third sleeve 71f. When the vehicle is under the floor of the vehicle room (i.e., the vehicle room is supported by the roof), one set of auxiliary support members 101f can be deployed without affecting the subsequent vehicle from under the floor of the vehicle room (i.e., the vehicle room is no longer supported by the roof).

[0240] When storing, if Figure 57 , release the connection between the auxiliary support 101f and the main leg 101a, and then rotate the auxiliary support 101f upward to a state parallel to the second sleeve 71e. At this time, the auxiliary support 101f is located below the sleeve, and then rotate the auxiliary support 101f around the second sleeve 71e, and transfer the auxiliary support 101f to the rear side of the second sleeve 71e. In this way, the auxiliary support 101f can be stacked and stored together with the floor unfolding and retracting mechanism 70, and after storage, it is on the same layer as the floor unfolding and retracting mechanism 70, so the height after storage will not be increased.

[0241] like Figure 1 and Figure 56The side wall supporting device 102 includes a first main support rod 102a, a second main support rod 102b, a third main support rod 102c, a first horizontal connecting member 102d and a second horizontal connecting member 102e.

[0242] When the car house is unfolded, the first main support rod 102a is located on the outside of the left wall 30 (i.e. the left side), the top end is detachably connected to the left wall 30, and the bottom end is rotatably connected to the first horizontal connecting member 102d; the second main support rod 102b is located on the outside of the right wall 40 (i.e. the right side), the top end is detachably connected to the right wall 40, and the bottom end is rotatably connected to the second horizontal connecting member 102e; the third main support rod 102c is located on the outside of the rear side wall 20 (i.e. the rear side), the top end is connected to the rear side wall 20, and the bottom end is rotatably connected to the rear sleeve (second sleeve 71e); the bottom end of the first main support rod 102a is tilted to the left relative to the top, the bottom end of the second main support rod 102b is tilted to the right relative to the top, and the bottom end of the third main support rod 102c is tilted backward relative to the top. The tilted design is conducive to improving the stability of the support.

[0243] like Figure 9 The first horizontal connector 102d is plugged into a set of connecting shafts 704 of the floor deployment mechanism and can slide left and right along the connecting shafts. The second horizontal connector 102e is plugged into another set of connecting shafts 704 of the floor deployment mechanism and can slide left and right along the connecting shafts. Specifically, each of the first and second horizontal connectors 102d and 102e includes a connecting rod 1021 and end rods 1022 connected to both ends of the connecting rod 1021. The end rods 1022 are plugged into the connecting shafts 704, and the bottom ends of the first and second main supports 102a and 102b are connected to the corresponding connecting rods 1021.

[0244] When expanded, Figure 17 , slide the first horizontal connecting member 102d to the left, slide the second horizontal connecting member 102e to the right, and lock it after sliding into place. Figure 1 , connecting the top of the first main support rod 102a and the left wall 30, and connecting the top of the second main support rod 102b and the right wall 40.

[0245] When storing, the connection between the first main support rod 102a and the left wall 30 and the connection between the second main support rod 102b and the right wall 40 are released, and then the first main support rod 102a and the second main support rod 102b are rotated so that they are parallel or collinear with the connecting rod 1021 of the first horizontal connecting member 102d and the connecting rod 1021 of the second horizontal connecting member 102e. Figure 9Two first main rods 102a are provided. One is rotated and accommodated parallel to the connecting rod 1021 of the first horizontal connector 102d. The other is rotated and accommodated collinearly with the connecting rod 1021 of the first horizontal connector 102d and then slid into the inner cavity of the connecting rod 1021. Similarly, two second main rods 102b are provided. One is rotated and accommodated parallel to the connecting rod 1021 of the second horizontal connector 102e. The other is rotated and accommodated collinearly with the connecting rod 1021 of the first horizontal connector 102e and then slid into the inner cavity of the connecting rod 1021. Then, the first horizontal connector 102d is unlocked and slid to the right, while the second horizontal connector 102e is slid to the left. The third main rod 102c is disconnected from the rear side wall 20, and then the third main rod 102c is rotated until it is parallel to the second sleeve 71e.

[0246] like Figure 17 The side wall supporting device 102 also includes a door entrance platform 102f. The right side of the door entrance platform 102f is rotatably connected to the connecting rod 1021 of the second horizontal connecting member 102e, and can rotate around the connecting rod 1021. When it rotates to a predetermined position, the left side of the door entrance platform 102f is supported on the floor (for example, a lower guide member is provided on the outer frame of the floor 60, which can be used for such support). Specifically, a buckle groove can be provided on the left side of the door entrance platform 102f so that it can be tightly buckled with the floor through the buckle groove.

[0247] like Figure 56 The side wall supporting device 102 also includes a first reinforcing support rod 102g and a second reinforcing support rod 102h. When the car-mounted room is unfolded, the bottom end of the first reinforcing support rod 102g is detachably connected to the left frame edge of the floor 60, and the bottom end of the second reinforcing support rod 102h is detachably connected to the right frame edge of the floor 60. The top end of the first reinforcing support rod 102g is rotatably connected to the first main support rod 102a, and the top end of the second reinforcing support rod 102h is rotatably connected to the second main support rod 102b. The top end of the first reinforcing support rod 102g is inclined to the left relative to the bottom end, and the top end of the second reinforcing support rod 102h is inclined to the right relative to the bottom end, respectively forming a triangular skeleton with one of the first main support rods 102a and one of the second main support rods 102b to improve the support stability.

[0248] The bottom end of the first reinforcing rod 102g is detachably connected to the left frame edge of the floor 60, and the bottom end of the second reinforcing rod 102h is detachably connected to the right frame edge of the floor 60. As a result, the triangular frame design enables the first main rod 102a and the second main rod 102b connected thereto to be connected to the left wall 30 and the right wall 40 respectively by sliding connection, for example, Figure 58The T-shaped connecting parts at the top of the first main support rod 102a and the second main support rod 102b are inserted into the open sliding grooves S on the left and right walls 30, 40, etc., which not only prevents the left and right walls 30, 40 from swaying left and right, but also allows the left and right walls 30, 40 to slide up and down (if the left and right walls 30, 40 need to slide up and down), and the top of the first main support rod 102a and the second main support rod 102b can be directly connected to the left and right walls 30, 40 respectively on the ground.

[0249] When storing, the first reinforcing rod 102g is disconnected from the floor 60 and the second reinforcing rod 102h is disconnected from the floor 60, and then the first reinforcing rod 102g and the second reinforcing rod 102h are rotated to be parallel to the first main rod 102a and the second main rod 102b respectively, and then rotated together with the first main rod 102a and the second main rod 102b to be parallel to the connecting rod 1021 ( Figure 17 and Figure 57 status shown).

[0250] By adopting the support mechanism provided by this solution, the vehicle-mounted house is stable as a whole in the unfolded state and is not prone to shaking or deformation. Moreover, the support mechanism 100 can be stacked and stored together with other components of the vehicle-mounted house - the floor 60, the roof 50, the side walls, the floor unfolding and retracting mechanism 70, the lifting mechanism 80, etc., without the need to be disassembled for separate storage, and the side walls 30 and 40 are allowed to slide up and down. Therefore, there are fewer scattered parts and good integrity in the stored state of the vehicle-mounted house. Moreover, the support mechanism after storage is on the same layer as the other components of the vehicle-mounted house or is located inside the other components, so the plane area and height of the vehicle-mounted house after storage will not be significantly increased, thereby meeting the restrictions on the plane area and height when the vehicle-mounted house is stored on the roof.

[0251] Facility composition 90

[0252] like Figure 59 In this embodiment, the facility component 90 includes first-class living facilities 904 , second-class living facilities 905 and partition facilities 906 .

[0253] The first type of living facilities 904 are tall facilities that are difficult to stack and store, and include sinks 9041, toilets 9042, and / or portable air conditioners. Toilets can be portable. Mobile air conditioners are air conditioners that combine an outdoor unit with a wall mount and can be moved indoors. The electrical components of the vehicle's cabin can draw power from the vehicle's own power supply (such as a battery), or additional power supply components can be configured for the vehicle's cabin.

[0254] The second type of living facilities 905 are facilities with plate-like components as the main body, which are easy to stack and store. The height of this type of facilities in the stored state is much smaller than the height in the used state.

[0255] The partition facility 906 is a facility used to separate the space in a room. The space in the room can be divided into multiple independent spaces to be used as a bathroom, bedroom, living room, kitchen, etc.

[0256] like Figure 59 In this embodiment, the facility assembly 90 also includes a facility box for accommodating first-category living facilities 904. The illustrated solution includes a first facility box 901a and a second facility box 901b. The interior spaces of the first and second facility boxes 901a and 901b are independent of each other. The first facility box 901a accommodates kitchenware, including a sink 9041, and can also accommodate a portable air conditioner. The second facility box 901b accommodates sanitaryware, including a toilet 9042, and can also accommodate a portable air conditioner. When the vehicle cabin is deployed, the facility box is located outside the vehicle cabin.

[0257] like Figure 59 When the vehicle room is unfolded, a passage is provided on one side of the facility box (the front side in the figure), and the side where the passage of the facility box is located is adjacent to the side wall. In the illustrated scheme, the side where the passage of the facility box is located is adjacent to the rear side wall 20. With this design, the sink 9041, toilet 9042, etc. in the facility box can pass through the passage of the facility box into the vehicle room (the mobile air conditioner in the facility box can still remain in the facility box).

[0258] like Figure 59 , an opening and closing door can be installed at the passage. In the illustrated scheme, the opening and closing door (i.e., the movable side wall panel X22a) is connected to the side wall (i.e., the rear side wall 20) adjacent to the passage of the facility box, is a part of the rear side wall 20, and participates in the construction of the rear side wall 20. The passage of the facility box is opened and closed by moving the opening and closing door left and right. Of course, the opening and closing form of the opening and closing door is not limited to sliding. For example, it can also be opened and closed by rotation. In addition, the opening and closing door can also be connected to the facility box instead of the side wall. The opening and closing door is set. When the vehicle-mounted room is in the unfolded state, after the sink 9041, toilet 9042, etc. are stored in the facility box, the opening and closing door can be closed to block the passage of the facility box, thereby achieving dry and wet separation to a certain extent.

[0259] like Figure 60 The sink 9041 and the toilet 9042 are connected to the corresponding facility box through a set of slide rails 90A. Figure 60 Slide the water tank 9041 out of the facility box and then slide it along the direction of the arrows A and B in the middle. Figure 60 Flip it in the direction of the middle C arrow to an appropriate height position. After flipping into place, the water tank 9041 is basically attached to the rear side wall 20 (the state shown in Figure 61).

[0260] Combine Figure 3 and Figure 64The facility assembly 90 also includes a box stand 905 supported at the bottom of the facility box. A swing arm is connected between the box stand 905 and the facility box. The swing arm adjusts the height of the facility box by swinging it. When the box is stowed, it is lowered. When it is deployed, it is raised so that the bottom wall of the facility box is roughly flush with the floor. This allows living facilities such as a toilet to slide smoothly into the vehicle compartment along the floor. The facility box and box stand 905 can be placed near the rear of the vehicle for a more comfortable driving experience.

[0261] The box seat 905 can be connected to the floor unfolding and retracting mechanism 70. Specifically, Figure 14 and Figure 11 The floor deployment mechanism 70 includes a first connecting portion 71a, a second connecting portion 71b, and a fifth connecting portion 71c. The fifth connecting portion 71c is connected to the front of the first connecting portion 71a and can slide forward relative to the first connecting portion 71a. The second connecting portion 71b is connected to the rear of the first connecting portion 71a and can slide rearward relative to the first connecting portion 71a, thereby driving the third and fourth floor panels 63 and 64 connected thereto to deploy rearward. The floor deployment mechanism 70 can be placed on the vehicle roof in either a forward or reverse orientation. When placed on the roof, the first connecting portion 71a is fixed to the roof bracket. When placed on the roof in a forward orientation, the second connecting portion 71b is positioned closer to the front of the vehicle. When placed on the roof in a reverse orientation, the fifth connecting portion 71c is positioned closer to the front of the vehicle. When placed on the roof, the second and fifth connecting portions 71b and 71c slide along the vehicle's length.

[0262] The box holder 905 can be connected to the first connection portion 71a of the floor deployment mechanism 70. During deployment, the box holder 905 does not move in the vehicle length direction. Alternatively, the box holder 905 can be connected to the second connection portion 71b of the floor deployment mechanism 70. During deployment, the box holder 905 and the facility box slide together along the second connection portion 71b to the appropriate position. Alternatively, the box holder 905 can be connected to the fifth connection portion 71c of the floor deployment mechanism 70. During deployment, the box holder 905 and the facility box slide together along the fifth connection portion 71c to the appropriate position.

[0263] Specifically, the facility box is slidably connected to the box seat 905. The facility box can slide horizontally relative to the box seat 905, and the sliding direction is parallel to the side wall adjacent to the through-hole. This design can avoid the X-shaped cross arm of the lifting mechanism 80 arranged on the outside of the side wall, leaving enough space for the X-shaped cross arm to move. Figure 3 、 Figure 62 and Figure 63 As shown in the figure, the first facility box 901a and the second facility box 901b are both connected to the same box seat 905. The first facility box 901a and the second facility box 901b are both adjacent to the rear side wall 20. Both can slide horizontally along the rear side wall 20 relative to the box seat 905 ( Figure 62In the direction indicated by the arrows A and B), when the first facility box 901a and the second facility box 901b slide to Figure 63 When the roof 50 is in the position shown, the lower end of the X-shaped cross arm can be avoided, leaving enough room for the X-shaped cross arm to move so that the X-shaped cross arm can stably support the roof 50.

[0264] like Figure 63 When the vehicle room is unfolded, the first facility box 901a and the second facility box 901b slide to a position spaced apart from each other. A flat fan 90B is installed on the side wall of the second facility box 901b to provide ventilation. Preferably, the fan 90B is installed on the side wall of the second facility box 901b adjacent to the first facility box 901a. In this way, when the vehicle room is stored, when the first facility box 901a and the second facility box 901b slide to a position adjacent to each other, the fan 90B can be blocked by the first facility box 901a (e.g., Figure 6 ) to avoid increasing driving resistance.

[0265] like Figure 65 , the first facility box 901a and the second facility box 901b are both provided with a take-in and take-out port and are equipped with a door 90C that closes the take-in and take-out port. The door 90C is installed on the side of the facility box that is not adjacent to the side wall so that the door 90C can be opened from outside the vehicle room. The internal volume of the first facility box 901a can be set to be larger than the volume of the sink 9041, so that after the sink 9041 is stored in the first facility box 901a, there is still extra space in the first facility box 901a to accommodate other kitchen utensils (such as rice cookers, barbecue grills, etc.) or other daily necessities. The user can open the door 90C of the first facility box 901a to take items in and out without unfolding the vehicle room, and can open the door 90C of the second facility box 901b to take out the toilet and empty it in a suitable position without unfolding the vehicle room.

[0266] like Figure 66 and Figure 67 The second type of living facilities 905 include plate-shaped main components. In the illustrated scheme, there are a first plate-shaped main component 9051, a second plate-shaped main component 9052, a third plate-shaped main component 9053, a fourth plate-shaped main component 9054, a fifth plate-shaped main component 9055, a sixth plate-shaped main component 9056, a seventh plate-shaped main component 9057, and an eighth plate-shaped main component 9058.

[0267] like Figure 66 and Figure 67The plate-shaped main body is hinged to the side wall or floor of the vehicle room. In the illustrated scheme, the first plate-shaped main body 9051 and the second plate-shaped main body 9052 are each hinged to the floor through a set of support members 9059. The third plate-shaped main body 9053, the fourth plate-shaped main body 9054 and the fifth plate-shaped main body 9055 are hinged to the front side wall 10. The sixth plate-shaped main body 9056 and the seventh plate-shaped main body 9057 are hinged to the right side wall 40. The eighth plate-shaped main body 9058 is hinged to the rear side wall 20. When storing, the plate-shaped main body is rotated to a position parallel to the side wall or floor to which it is hinged (such as Figure 66 ), when unfolding, rotate the plate-shaped main body member to a height position parallel to the floor and spaced a distance from the floor (such as Figure 67 ), which is in line with daily living habits. When in use, the user can flexibly choose to unfold all the plate-like main components, unfold part of the plate-like main components, or not unfold the plate-like main components according to needs.

[0268] The plate-like main body member can be unfolded to Figure 67 In the state shown, first plate-shaped main member 9051 and third plate-shaped main member 9053 are joined together and can be used as a bench or single bed, etc. Second plate-shaped main member 9052 and fourth plate-shaped main member 9054 are joined together and can be used as a bench or single bed, etc. Fifth plate-shaped main member 9055 and seventh plate-shaped main member 9057 are located in front of and behind sixth plate-shaped main member 9056, spaced apart from and lower than sixth plate-shaped main member 9056. In this state, fifth plate-shaped main member 9055 and seventh plate-shaped main member 9057 can be used as dining chairs, while sixth plate-shaped main member 9056 can be used as a dining table. Eighth plate-shaped main member 9058 is located near sink 9041 and can be used as a cutting board, cooking utensils, or storage table.

[0269] In the diagram, Figure 67 The first plate-shaped main body member 9051 and the second plate-shaped main body member 9052 are telescopic structures, each including a front plate portion 905a and a rear plate portion 905b. After the first plate-shaped main body member 9051 and the second plate-shaped main body member 9052 are unfolded, the rear plate portions 905b of the first plate-shaped main body member 9051 and the second plate-shaped main body member 9052 can be stretched backward as needed.

[0270] In the diagram, Figure 68 The seventh plate-shaped main body member 9057 is a folding structure, including a left plate portion 905d and a right plate portion 905c. After the seventh plate-shaped main body member 9057 is unfolded, the left plate portion 905d can be folded to a position where the right plate portion 905c is stacked as needed ( Figure 67 This increases the aisle width and facilitates passage.

[0271] In the diagram, Figure 67The sixth plate-shaped main body member 9056 can slide up and down, so that the height position of the sixth plate-shaped main body member 9056 can be adjusted to the same height as the fifth plate-shaped main body member 9055 ( Figure 68 The sixth plate-shaped main body member 9056 can slide forward and backward, making the horizontal position of the sixth plate-shaped main body member 9056 adjustable and capable of being adjusted to a position where it can be spliced ​​with the fifth plate-shaped main body member 9055. The seventh plate-shaped main body member 9057 can slide forward and backward, making the horizontal position of the seventh plate-shaped main body member adjustable and capable of being spliced ​​with the sixth plate-shaped main body member 9056. The fifth plate-shaped main body member 9055, the sixth plate-shaped main body member 9056, and the seventh plate-shaped main body member 9057 can be spliced ​​together to form a bed.

[0272] In addition, recessed areas 90D ( Figure 67 The figure shows a recessed area 90D on the floor. When stowed, the plate-like main body member at least partially sinks into the recessed area of ​​the side wall or floor. This way, when stowed, the plate-like main body member takes up little or no height of the stacked structure, thus ensuring the stacked structure's height remains within the specified limits. Furthermore, the vehicle compartment can be equipped with an inflatable airbag, which can serve as a mattress or seat cushion. When stowed, the airbag (after deflation) can be stored in the recessed area.

[0273] like Figure 67 The second type of living facilities also includes a support member 9059 for supporting the plate-like main body member. In the unfolded state, the support member 9059 is roughly perpendicular to the floor 60, the bottom end is supported on the floor 60, and the top end supports the plate-like main body member, so that the plate-like main body member is stable at the target height position.

[0274] The top and bottom ends of the support member 9059 can both be hinged ends, hinged to the plate-like main body member and the floor hinged end respectively, or one end can be a hinged end and the other end can be a free end. The support member 9059 can rotate relative to the floor or plate-like main body member hinged to it. When stored, the support member 9059 is rotated to a position parallel to the floor or plate-like main body member hinged to it.

[0275] In addition, a recessed area may be provided on the plate-like main body component hinged to the support member 9059, so that the support member 9059 after storage is at least partially sunken into the recessed area of ​​the plate-like main body component, or the support member 9059 after storage is at least partially sunken into the recessed area of ​​the floor or side wall. In this way, after storage is completed, the support member 9059 does not occupy a single layer of the stack, thereby helping to ensure that the height of the stack does not exceed the limit.

[0276] In the illustrated embodiment, the support members supporting the front plate portion 905a of the first plate-shaped main body member 9051 and the support members supporting the front plate portion 905a of the second plate-shaped main body member 9052 are both hinged at the top and bottom ends, with the top ends hinged to the front plate portion 905a of the corresponding plate-shaped main body member and the bottom ends hinged to the floor, as shown in FIG. Figure 69 When the first plate-like main body structure 9051 and the second plate-like main body structure 9052 are extended and retracted, the two groups of supporting members 9059 swing relative to the floor.

[0277] In the illustrated scheme, the supporting components of the rear plate portion 905b of the first plate-shaped main body member 9051, the rear plate portion 905b of the second plate-shaped main body member 9052, the third plate-shaped main body member 9053, the fourth plate-shaped main body member 9054, the fifth plate-shaped main body member 9055, the sixth plate-shaped main body member 9056, and the seventh plate-shaped main body member 9057, these supporting components can be hinged to the floor at the bottom end and the top end is a free end, or the top end can be a hinged end and the bottom end can be a free end. When stored, these supporting components are stored in the recessed area of ​​the floor.

[0278] In the diagram, Figure 66 and Figure 67 The partition facility 906 includes a first partition wall 9061, a second partition wall 9062, and a third partition wall 9063. The first partition wall 9061 is hinged to the left side wall 30, one side of the third partition wall 9063 is hinged to the second partition wall 9062, and the other side of the third partition wall 9063 is hinged to the rear side wall 20. The space enclosed by these three partition walls after unfolding can be used as a bathroom, and a toilet is located in the bathroom. In addition, a shower facility can also be arranged in the bathroom. The partition wall can be arranged in an upper and lower part, that is, it includes an upper partition part and a lower partition part. The upper partition part and the lower partition part are connected and can slide up and down relative to the lower partition part. When stored, the upper partition end can be slid to a position stacked with the lower partition part, and then the whole can be rotated to a position parallel to the side wall. A recessed area can be provided on the inner side of the side wall. After storage, the partition wall is at least partially located in the recessed area of ​​the side wall, which is conducive to ensuring that the height of the stacked body does not exceed the limit.
