[0020] The Fig. Figures 1 to 9 illustrate a first embodiment of the convertible house with a pitched roof of the present utility model, comprising a main room 100, a primary extension room 200, a secondary extension room 900, and a first sliding mechanism 300A and a second sliding mechanism 300B, which are arranged on two adjacent side edges of the main room 100. The primary extension room 200 is connected to the main room 100 via the first sliding mechanism 300A, allowing the primary extension room 200 to be extended and retracted. The secondary extension room 900 is connected to the main room 100 via the second sliding mechanism 300B, allowing the secondary extension room 900 to be extended and retracted. The main room 100 is movably connected to a roof covering 400. The outer wall of both the main room 100 and the primary extension room 200 is each connected to a lifting mechanism.

[0021] The main room 100, the primary extension room 200, and the secondary extension room 900 serve for arranging furniture and / or interior design. The first sliding mechanism 300A and the second sliding mechanism 300B allow the convertible house to be folded out and in, effectively meeting the spatial requirements of its users. The roof cover 400 serves as sun protection or rain protection. The lifting mechanism allows the main room 100, the primary extension room 200, and the secondary extension room 900 to be raised, creating space for loading operations underneath. Once the flatbed truck is directly below the main space 100 and the primary extension space 200 or the secondary extension space 900, the main space and the primary extension space 200 or 900 can be opened by retracting the lifting mechanism.The secondary expansion space 900 can be lowered onto the loading platform of the flatbed truck, which makes loading easier.

[0022] As in Fig. As shown in Figures 3 and 7 to 9, the lifting mechanism comprises a first lifting mechanism 510 and a second lifting mechanism 520, respectively, arranged on the side of the main chamber 100 and the side of the primary extension chamber 200, respectively, and further an extension mechanism 530, wherein the fixed end of the first lifting mechanism 510 is connected to the outer wall of the main chamber 100 via the extension mechanism 530 and the fixed end of the second lifting mechanism 520 is connected to the outer wall of the primary extension chamber 200, while the lifting end of both the first lifting mechanism 510 and the second lifting mechanism 520 is oriented towards the floor and the extension direction of the extension mechanism 530 is parallel to the sliding direction of the first sliding mechanism 300A.The extension mechanism 530 facilitates the adjustment of the distance between the first lifting mechanism 510 and the second lifting mechanism 520, making the convertible house suitable for loading flatbed trucks of various specifications and increasing operational flexibility.

[0023] As in Fig. 3 and Fig. 7 and Fig. As shown in Figure 9, the first lifting mechanism 510 comprises a vertically arranged outer lifting tube 511, an inner lifting tube 512, and a first telescopic section 513. The inner lifting tube 512 is slidably inserted into the outer lifting tube 511, with the inner lifting tube 512 and the outer lifting tube 511 being aligned to improve the stability of the lifting process. The fixed end and the telescopic end of the first telescopic section 513 are each connected to the inner wall of the outer lifting tube 511 and the inner wall of the inner lifting tube 512, respectively. A support leg 514 is connected to the end of the inner lifting tube 512 closest to the ground and / or a support leg 514 is connected to the telescopic end of the first telescopic section 513. The fixed and movable ends of the extension mechanism 530 are each connected to the underside of the main chamber 100 and the outer side wall of the outer lifting tube 511.In this embodiment, the first telescopic section 513 comprises a first electric push rod, wherein the fixed end of the first electric push rod is connected to the inner side wall of the outer lifting tube 511 and the telescopic end of the first electric push rod is connected to the inner side wall of the inner lifting tube 512. Preferably, the support leg 514 is attached to the end position of the telescopic end of the first electric push rod, and the support leg 514 is arranged outside the inner lifting tube 512. When the first electric push rod extends, it drives the inner lifting tube 512 to extend out of the outer lifting tube 511 and simultaneously lowers the support leg 514 until it touches the ground. When the first electric push rod retracts, the support leg 514 is lifted off the ground. In this embodiment, the second lifting mechanism 520 is structurally similar to or identical with the first lifting mechanism 510.The convertible house can be smoothly lifted using the first lifting mechanism 510 and the second lifting mechanism 520. It should be noted that both the first lifting mechanism 510 and the second lifting mechanism 520 can be configured with one or more lifting mechanisms, depending on the actual application scenario.

[0024] As in Fig. As shown in Figure 9, the extension mechanism 530 comprises a horizontally arranged extension outer tube 531, an extension inner tube 532, and a third telescopic section 533. The extension inner tube 532 is slidably inserted into the extension outer tube 531, with the extension inner tube 532 and the extension outer tube 531 being aligned to improve the stability of the extension process. The fixed end and the telescopic end of the third telescopic section 533 are each connected to the inner wall of the extension outer tube 531 and the inner wall of the extension inner tube 532, respectively. The end of the extension inner tube 532 furthest from the extension outer tube 531 is connected to the outer lifting tube 511. The outer side wall of the extension outer tube 531 is connected to the underside of the main chamber 100. In this embodiment, the third telescopic part 533 represents a third electric push rod.The fixed end of the third electric push rod is attached to the inner side wall of the outer lifting tube 511 via a pin joint, while the telescopic end of the third electric push rod is attached to the inner side wall of the inner lifting tube 512 via a pin joint.

[0025] As in Fig. As shown in Figures 7 to 9, the main chamber 100 includes a recess 121 for receiving the first lifting mechanism 510, the recess 121 further comprising a first cover mechanism 610. In this embodiment, the outer wall of the primary extension chamber 200 is provided with a second cover mechanism 620 at the location corresponding to the second lifting mechanism 520. The first cover mechanism 610 and the second cover mechanism 620 facilitate maintenance and inspection of the lifting mechanism and also serve a decorative purpose. In this embodiment, the first cover mechanism 610 comprises a first cover flap that is pivotably connected to the outer side wall of the main chamber 100. In particular, the first cover flap can be connected to the main chamber 100 via a pivot axis or an elastic pivoting mechanism, and a locking mechanism compatible with the first cover flap can also be provided on the outside of the main chamber 100.It should be noted that the second cover mechanism 620 has a similar or identical structure to the first cover mechanism 610. In this embodiment, the second cover mechanism 620 comprises a second cover flap that is rotatably connected to the outer wall of the primary expansion chamber 200. To enable the second cover flap to enclose the second lifting mechanism 520, the cross-section of the second cover flap can be, as shown in [reference]. Fig. 8 shown, be L-shaped.

[0026] As in Fig. Figures 7 to 9 show that, if necessary, the first and second cover flaps are opened. The third electric push rod extends, causing the first lifting mechanism 510 to move outwards away from the main chamber 100. This increases the distance between the first lifting mechanism 510 and the second lifting mechanism 520, facilitating the insertion of the flatbed truck directly beneath the convertible house. Simultaneously, both the first and second lifting mechanisms 520 extend to perform the lifting movement. As the flatbed truck is inserted, the first and second lifting mechanisms 510 retract, and the third electric push rod retracts, pulling the first lifting mechanism 510 into the recess 121. The first and second cover flaps are then closed.

[0027] As in Fig. 3, Fig. 4, Fig. 5 and Fig. Figure 6 shows that the main space 100 comprises a main floor 110 and a main side wall 120 connected to the main floor 110, wherein the primary extension space 200 comprises a hinged floor assembly 210, a floor section 220 and an extension side wall 230, wherein the extension side wall 230 is connected to the floor section 220 and both ends of the hinged floor assembly 210 are hinged to the main floor 110 and the floor section 220 respectively, wherein the main floor 110 and the floor section 220 are configured such that one of them is connected to the fixed end of the first sliding mechanism 300A, while the other is connected to the sliding end of the first sliding mechanism 300A.

[0028] As in Fig. 3, Fig. 4 and Fig. Figure 7 shows that the first sliding mechanism 300A comprises a horizontal telescopic section 310, wherein the fixed end and the telescopic end of the horizontal telescopic section 310 are each connected to the underside of the main floor 110 and the floor section 220, respectively. The hinged floor assembly 210 comprises a first hinge plate 211 and a second hinge plate 212. One end of the first hinge plate 211 is hinged to the main floor 110, while the other end of the first hinge plate 211 is hinged to one end of the second hinge plate 212. The other end of the second hinge plate 212 is hinged to the floor section 220. In this embodiment, the horizontal telescopic section 310 represents a fourth electric push rod. The fixed end of the fourth electric push rod is connected to the underside of the main floor 110, while the telescopic end of the fourth electric push rod is connected to the underside of the floor section 220.When the fourth electric pushrod is in the retracted position, the first folding panel 211 and the second folding panel 212 are in a folded position. The main floor 110 is close to the floor section 220, and both remain on the same horizontal plane. At this point, the extension side wall 230 and the main side wall 120 are in the position shown in [reference missing]. Fig. Figure 6 shows the retracted position. When the fourth electric push rod is in the extended position, the first folding plate 211 and the second folding plate 212 are in a flattened position. Together with the main floor 110 and the floor section 220, they form, as shown in Fig. 3 and Fig. 4 shown, the first folding panel 211 and the second folding panel 212 form a flat surface structure that forms the floor of the extended convertible house.

[0029] In this embodiment, the main side wall 120 comprises a front panel, a rear panel, and a side panel, forming a semi-enclosed structure. The extension side wall 230 forms a semi-enclosed structure similar to the main side wall 120, wherein the main side wall 120 and the extension side wall 230 are designed for a nested configuration. It should be noted that when the main side wall 120 and the extension side wall 230 are in a relatively retracted state, the main side wall 120 may be located outside the extension side wall 230, or alternatively, the extension side wall 230 may be located outside the main side wall 120. The preferred embodiment is that in which the extension side wall 230 is located outside the main side wall 120 when both are in the retracted state, as shown in [Figure 1]. Fig. 8 is shown. In this embodiment, as in Fig. 8 and Fig. Figure 9 shows the extension outer tube 531 attached to the underside of the main floor 110. The first cover flap is located at the position of the side plate of the main side wall 120, while the second cover flap is located at the position of the side plate of the extension side wall 230.

[0030] In this embodiment, an access door can be provided on the main side wall 120 to facilitate entry and exit from the convertible house. As in Fig. As shown in Figure 8, a first access door 150, which can be opened by pivoting, is provided on the side wall of the main side wall 120, while a second access door 160, which can also be opened by pivoting, is provided either on the front panel or the rear panel of the main side wall 120. Appropriate door locks may also be provided. Of course, the access door can also be positioned in other locations, for example, on the first expansion room 200 or the second expansion room 900.

[0031] As in Fig. As shown in Figures 1 and 3 to 7, the roof covering 400 comprises a first cover plate 410, which is pivotally connected to the main chamber 100, a second cover plate 420, which is connected at an angle to the first cover plate 410, and further a second telescopic section 430, wherein the first cover plate 410 is connected to the inside of the main chamber 100 via the second telescopic section 430, and when the second telescopic section 430 is in the retracted position and the primary extension chamber 200 is retracted relative to the main chamber 100, the first cover plate 410 is located above the main chamber 100, with the second cover plate 420 being positioned as shown in Figure 1. Fig. Figure 7 shows the area on the outside of the primary extension space 200. The angled connection between the first cover plate 410 and the second cover plate 420 creates more interior height in the convertible house. This design allows the roof cover 400 to protect against rain while simultaneously facilitating water runoff, thus increasing practicality. The top of the primary extension space 200 is connected to a positioning section 240, and when the second telescopic section 430 is extended and the primary extension space 200 is unfolded relative to the main space 100, the second cover plate 420 is positioned as shown in Figure 7. Fig. Figures 3 to 5 are shown at positioning section 240. The angled connection between the first cover plate 410 and the second cover plate 420 creates more interior height in the convertible house. This design allows the roof covering 400 to protect against sun and rain while simultaneously facilitating heat dissipation and water runoff, thus increasing its practicality.

[0032] In this embodiment, one end of the first cover plate 410 is connected to the top of the main side wall 120 via a hinge, while the other end of the first cover plate 410 is attached at an angle to one end of the second cover plate 420, thus forming a V-shape for the roof cover 400. In this embodiment, several stiffening ribs are also arranged between the first cover plate 410 and the second cover plate 420, thereby increasing the stability of the roof cover 400. In particular, the stiffening ribs are arranged near the junction between the first cover plate 410 and the second cover plate 420. In this embodiment, the second telescopic section 430 represents a second electric push rod. The fixed end of the second electric push rod is connected to the inside of the main side wall 120 via a hinge, more precisely, it is pivotally attached to the side plate of the main side wall 120.The telescopic end of the second electric pushrod is connected to the underside of the first cover plate 410 via a hinge. As in . Fig. As shown in Figure 5, the positioning section 240 comprises an inner eave 241, which is connected to the top of the extension side wall 230. A buffer element 242 is arranged on the inner eave 241, with the other end of the second cover plate 420 abutting the buffer element 242. It should be noted that the buffer element 242 can also be designed as an elastic buffer body.

[0033] The operating principle of the convertible house with a pitched roof in this exemplary embodiment is as follows: When the convertible house is in Fig. As the retracted state shown in Figure 7 transitions to the extended state, the second telescopic section 430 extends and raises the roof cover 400. Subsequently, the horizontal telescopic section 310 extends and drives the primary expansion chamber 200 to move outwards. The hinged floor assembly 210 changes from its folded state to an unfolded state, while the primary expansion chamber 200 also extends relative to the main chamber 100. The second telescopic section 430 then retracts slightly, causing the second cover plate 420 to rest against the positioning section 240, thus aligning as shown in Figure 7. Fig. 3 and Fig. Figure 4 shows the transition to the unfolded state. The convertible house with a pitched roof, consisting of a sloping roof structure formed by the first cover plate 410 and the second cover plate 420, unfolds, creating a distinctive visual effect that immediately draws attention upon setup. This unique appearance attracts more users to experience the accommodation. Inside, the convertible house offers a generously high interior, ensuring a comfortable living experience for its occupants.

[0034] When the convertible house needs to be loaded, the extension mechanism 530 pushes the first lifting mechanism 510 outwards. The first lifting mechanism 510 and the second lifting mechanism 520 then extend to raise the main room 100 and the primary extension room 200. Once the flatbed truck is positioned beneath the main room 100 and the primary extension room 200, the main room 100 and the primary extension room 200 are lowered onto the flatbed truck. Example II

[0035] This embodiment represents a second embodiment of the convertible house with a pitched roof. It is similar to the first embodiment and differs from it only in that the underside of the main floor 110 is as in Fig. 6 and Fig. Figure 7 shows a sliding mechanism 300A connected to a plurality of crossbeams 130, the first sliding mechanism comprising a rail 320 and a plurality of rolling elements 330, the rail 320 being slidably connected to the crossbeams 130 via the rolling elements 330, and the rail 320 being connected to the underside of the bottom section 220. The rail 320 and the rolling elements 330 serve to better guide the movement of the primary expansion space 200 and thereby increase stability during both extension and retraction. In this embodiment, the rolling element 330 can be configured as a rail guide roller, allowing the rail 320 to slide over the rail guide roller on the crossbeam 130. This allows the movement of the floor section 220 and the associated extension side wall 230, whereby the folding floor assembly 210 can be folded in or out accordingly.

[0036] To increase the stability of the convertible house, the crossbeams 130 are additionally connected by a series of longitudinal beams 140. The extension tube 531 and the horizontal telescopic section 310 are located between the main floor 110 and the longitudinal beam 140. Furthermore, both the extension tube 531 and the horizontal telescopic section 310 can be attached to the longitudinal beam 140 via fasteners.

[0037] The operating principle of the convertible house with a pitched roof in this exemplary embodiment is as follows: When the convertible house switches between its retracted and extended states, the rail 320 on the crossbeam 130 can extend and retract together with the horizontal telescopic section 310. This coordinated movement drives the sliding of the primary extension space 200, thus improving the stability of both the extension and retraction processes of the convertible house. Example III

[0038] This embodiment represents a third embodiment of the convertible house with a pitched roof. This embodiment is similar to embodiments I or II and differs only in that, as in Fig. 3, Fig. 7 and Fig. Figure 9 shows that the convertible house with a pitched roof additionally comprises a plurality of retractable rollers 700 arranged on the underside of the main room 100 and / or the primary extension room 200.
