[0035] Please also read Figure 1 and Figure 2 In a first aspect, an embodiment of the present invention discloses a chassis structure 1 with a movable home unit 12, which is applied to an assembled building. The chassis structure 1 includes a base 10, a lifting device 11, a home unit 12 and a moving device 13. The base 10 has a receiving cavity 100 and a first surface 101. The first surface 101 is used to form at least a portion of the floor surface of the assembled building. The base 10 is provided with an opening 102 penetrating the first surface 101, and the opening 102 is connected to the receiving cavity 100. The lifting device 11 is provided in the receiving cavity 100. The home unit 12 is carried by the lifting device 11. The lifting device 11 is used to drive the home unit 12 to move relative to the base 10, so that the home unit 12 is located in the receiving cavity 100, or so that the home unit 12 protrudes from the first surface 101 through the opening 102. The moving device 13 is provided in the home unit 12. The moving device 13 is used to drive the home unit 12 to move to a preset position of the first surface 101 when the home unit 12 protrudes from the first surface 101.

[0036] The first aspect of the embodiment of the present invention provides a chassis structure 1 with a movable home unit 12, the home unit 12 is preset in the accommodating cavity 100 of the base 10, and the first surface 101 of the base 10 can be used as at least part of the floor surface of the prefabricated building. The chassis structure 1 is installed on the prefabricated building, that is, the installation of the floor surface of the prefabricated building and the home unit 12 is completed at the same time, and there is no need to carry and install the home unit 12 separately, which further improves the construction efficiency of the prefabricated building. In addition, through the lifting device 11, the home unit 12 can be moved relative to the base 10, so that the home unit 12 can be located in the accommodating cavity 100, reducing the overall volume of the chassis structure 1, and facilitating the transportation of the chassis structure 1. At the same time, when the user does not need to use the home unit 12, the home unit 12 can be stored in the accommodating cavity 100, saving the indoor space of the prefabricated building, and the home unit 12 can be protruded from the first surface 101 through the opening 102 opened on the base 10, so that the user can use the home unit 12. At the same time, by setting up a moving device 13, when the home unit 12 is moved to a position protruding from the first surface 101 by the lifting device 11, the home unit 12 can be brought to a preset position on the first surface 101 by the moving device 13, which can facilitate the user to adjust the position of the home unit 12 when the prefabricated building is used.

[0037] Optionally, the home unit 12 may be bathroom appliances (such as bathtubs, toilets, etc.), kitchen appliances (such as stoves, cabinets, bars, etc.), furniture (such as beds, tables, sofas, chairs, etc.), electrical equipment (such as washing machines, dryers, refrigerators, lighting equipment, etc.), fitness equipment, ventilation equipment, floor heating and cooling radiation equipment, energy storage equipment, purification equipment, water supply equipment, sewage treatment equipment, etc., products for daily use by users in prefabricated buildings. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0038] Optionally, the base 10 may be a shell structure or a box structure, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0039] Optionally, the number of the home unit 12, the lifting device 11, and the mobile device 13 can be one or more, which can be selected according to actual conditions and is not specifically limited in this embodiment. When the number of the home unit 12 is multiple, the number of the lifting device 11 and the mobile device 13 can also be one, so as to achieve the position adjustment of multiple home units 12 at the same time. The number of the lifting device 11 and the mobile device 13 can also be multiple and correspond to the home unit 12 one by one, so as to achieve the position adjustment of multiple home units 12 respectively.

[0040] Optionally, there may be one or more preset positions, which may be selected according to actual conditions and are not specifically limited in this embodiment.

[0041] In some embodiments, the lifting device 11 includes a supporting plate 110, and the second surface 110a of the supporting plate 110 is used to support the mobile device 13. The supporting plate 110 can move relative to the base 10 so that the home unit 12 is located in the accommodating cavity 100, or so that the home unit 12 protrudes from the first surface 101 through the opening 102, and when the home unit 12 protrudes from the first surface 101 through the opening 102, the second surface 110a of the supporting plate 110 is flush with the first surface 101, and the second surface 110a is used to form a partial floor surface of the prefabricated building.

[0042] In this way, on the one hand, the bearing plate 110 of the lifting device 11 plays the role of bearing the home unit 12, so that the lifting device 11 can drive the home unit 12 to move relative to the base 10 through the bearing plate 110. On the other hand, when the bearing plate 110 drives the home unit 12 to protrude from the first surface 101 through the opening 102, and the second surface 110a of the bearing plate 110 is exactly flush with the first surface 101 of the base 10, the bearing plate 110 can also play the role of being used as at least part of the floor surface of the prefabricated building. The bearing plate 110 and the base 10 cooperate to make the floor surface of the prefabricated building more complete. In addition, the bearing plate 110 plays two roles at the same time, which simplifies the structure of the lifting device 11.

[0043] Exemplarily, the size of the carrier plate 110 is the same as the size of the opening 102. Thus, when the home unit 12 protrudes from the first surface 101 through the opening 102, the second surface 110a of the carrier plate 110 is flush with the first surface 101 and the carrier plate 110 is engaged with the opening 102, so that the first surface 101 and the second surface 110a form a complete surface, further improving the structural and appearance integrity of the first surface 101 and the second surface 110a when used as at least part of the floor surface of the prefabricated building.

[0044] Optionally, the lifting device 11 may include one or more of a jack, an electric push rod, a scissor mechanism 112, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0045] In some embodiments, the lifting device 11 also includes a mounting plate 111 and a scissors mechanism 112. The mounting plate 111 is disposed in the accommodating cavity 100. Both ends of the scissors mechanism 112 are respectively connected to the mounting plate 111 and the supporting plate 110. The scissors mechanism 112 is used to drive the supporting plate 110 to move relative to the mounting plate 111.

[0046] In this way, the scissor mechanism 112 and the supporting plate 110 can be conveniently installed in the accommodating cavity 100 through the mounting plate 111. The scissor mechanism 112 can drive the supporting plate 110 to move relative to the mounting plate 111, so that the supporting plate 110 drives the home unit 12 to be located in the accommodating cavity 100, or, so that the supporting plate 110 drives the home unit 12 to protrude from the first surface 101 through the opening 102. The scissor mechanism 112 has a simple structure and high working efficiency, and can drive the home unit 12 to move relatively smoothly, thereby improving the safety of the chassis structure 1.

[0047] In some embodiments, the scissor mechanism 112 includes an electric push rod 112a and a scissor bracket 112b, the two ends of the scissor bracket 112b along the height direction of the chassis structure 1 are respectively connected to the mounting plate 111 and the bearing plate 110, the fixed end of the electric push rod 112a is installed on the mounting plate 111, and the movable end of the electric push rod 112a is connected to the scissor bracket 112b. In this way, by controlling the extension and contraction of the movable end of the electric push rod 112a, the scissor bracket 112b can be driven to extend and deform, thereby realizing the movement of the bearing plate 110 relative to the mounting plate 111.

[0048] In some embodiments, the chassis structure 1 also includes a first positioning device 14, which is disposed in the accommodating cavity 100. The first positioning device 14 can move relative to the base 10 to avoid movement of the supporting plate 110 relative to the base 10, or, when the second surface 110a of the supporting plate 110 is flush with the first surface 101, the first positioning device 14 stops at the side of the supporting plate 110 that is away from the second surface 110a.

[0049] In this way, by setting the first positioning device 14, the first positioning device 14 can move to different positions relative to the base 10 so that the first positioning device 14 has different functions. The first positioning device 14 can avoid the movement of the supporting plate 110 relative to the base 10, so that the supporting plate 110 can drive the home unit 12 to move relative to the base 10, so that the home unit 12 is located in the accommodating cavity 100 or the home unit 12 protrudes from the first surface 101 through the opening 102. The first positioning device 14 can also stop at a side of the supporting plate 110 away from the second surface 110a when the second surface 110a of the supporting plate 110 is flush with the first surface 101, thereby facilitating the positioning of the second surface 110a of the supporting plate 110 when it needs to be flush with the first surface 101, and at the same time ensuring that the supporting plate 110 maintains a height at which the second surface 110a is flush with the first surface 101.

[0050] Optionally, the first positioning device 14 may be a movable latch, a hinge, etc. The driving mode of the first positioning device 14 may be manual driving or electric driving, which can be selected according to actual conditions and is not specifically limited in this embodiment.

[0051] Optionally, the moving device 13 may include one or more of wheels 131, guide rail slider mechanisms, push rod mechanisms, etc., which may be selected according to actual conditions and are not specifically limited in this embodiment.

[0052] In some embodiments, the mobile device 13 includes a mounting base 130 and a wheel 131. The mounting base 130 is connected to the home unit 12, and the wheel 131 is rotatably connected to the mounting base 130. When the home unit 12 protrudes from the first surface 101, the wheel 131 is used to drive the home unit 12 to move.

[0053] In this way, the wheel 131 can be easily installed on the home unit 12 through the mounting base 130, and the wheel 131 can rotate relative to the mounting base 130, so that when the home unit 12 protrudes from the first surface 101, the wheel 131 can drive the home unit 12 to move, thereby adjusting the position of the home unit 12 on the first surface 101 or the lifting device 11.

[0054] In some embodiments, the mounting base 130 is rotatably connected to the home unit 12 , and when the home unit 12 protrudes from the first surface 101 , the mounting base 130 is used to adjust the orientation of the wheel 131 relative to the base 10 .

[0055] In this way, by rotating the mounting base 130 relative to the home unit 12, the orientation of the wheel 131 relative to the base 10 can be adjusted, thereby adjusting the movement direction of the home unit 12 driven by the wheel 131, so that the home unit 12 can be moved to any position on the first surface 101 or the lifting device 11 through the moving device 13, further facilitating the user to move the home unit 12 to a desired position.

[0056] In some embodiments, the mobile device 13 also includes a first driver (not shown) and a second driver (not shown), the first driver is connected to the wheel 131, and the first driver is used to drive the wheel 131 to rotate relative to the mounting base 130, the second driver is connected to the mounting base 130, and the second driver is used to drive the mounting base 130 to rotate relative to the home unit 12, and the chassis structure 1 also includes a control device (not shown), the control device is electrically connected to the first driver and the second driver, and the control device is used to control the working status of the first driver and the second driver.

[0057] In this way, the first driver and the second driver can provide power for the rotation of the wheel 131 relative to the mounting base 130 and the rotation of the mounting base 130 relative to the home unit 12, and the control device can control the working status of the first driver and the second driver (the working status includes but is not limited to opening, closing, output power, etc. of the first driver and the second driver), that is, the direction of the wheel 131 and the moving distance of the wheel 131 can be controlled, thereby realizing the control of the home unit 12 moving to the preset position of the first surface 101, thereby improving the degree of automation of the chassis structure 1, and further facilitating the user to adjust the position of the home unit 12.

[0058] Optionally, the first driver and the second driver may be motors, hydraulic motors, etc., which can provide power for the rotation of the wheel 131 and the mounting seat 130. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0059] In this embodiment, the control device may also be electrically connected to the electric push rod of the scissor mechanism 112 to control the extension and retraction of the movable end of the electric push rod.

[0060] Optionally, the control device may be a touch panel, a joystick controller, a remote controller, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment. When the control device is a wired control device such as a touch panel or a joystick controller, the control device is electrically connected to the first driver and the second driver through a wire, etc. When the control device is a wireless control device such as a remote controller, the control device is wirelessly connected to the first driver and the second driver through Bluetooth or infrared communication.

[0061] Optionally, the control device can be arranged in the home unit 12 to facilitate electrical connection with the first driver and the second driver. The control device can also be arranged on the base 10 or the wall of the prefabricated building to facilitate centralized control of multiple home units 12. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0062] In some embodiments, the mobile device 13 also includes a first transmission mechanism (not shown) and a second transmission mechanism (not shown), the first transmission mechanism is connected to the wheel 131, the first transmission mechanism is used to drive the wheel 131 to rotate relative to the mounting base 130, and the second transmission mechanism is connected to the mounting base 130, the second transmission mechanism is used to drive the mounting base 130 to rotate relative to the home unit 12.

[0063] In this way, the user can manually control the first transmission mechanism and the second transmission mechanism to provide power for the rotation of the wheel 131 relative to the mounting seat 130 and the rotation of the mounting seat 130 relative to the home unit 12, thereby realizing the movement of the home unit 12 on the first surface 101. In addition, the structure of the mobile device 13 of this embodiment is relatively simple, and only requires the user to manually provide power, without providing energy such as electricity as power, and can be used in any environment, thereby improving the flexibility of the mobile device 13 and increasing the fun of the user when moving the home unit 12.

[0064] Optionally, the first transmission rod mechanism may be a crank rocker mechanism, a gear mechanism or a worm gear mechanism, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0065] Preferably, the first transmission mechanism may be a crank-rocker mechanism, the crank is connected to the wheel 131 , and the user may drive the rotation of the wheel 131 by shaking the rocker, thereby facilitating the user to manually control the rotation of the wheel 131 .

[0066] Optionally, the second transmission mechanism can be a gear mechanism or a worm gear mechanism, or a connecting rod, which is connected along the radial direction of the mounting seat 130. The user can adjust the orientation of the mounting seat 130 by manually rotating the connecting rod. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0067] In some embodiments, the chassis structure 1 also includes a cover plate 15, which is movably connected to the base 10. The cover plate 15 can move relative to the base 10 to cover or open the opening 102. When the cover plate 15 covers the opening 102, the third surface 150 of the cover plate 15 is flush with the first surface 101, and the third surface 150 is used to form a partial floor surface of the prefabricated building.

[0068] In this way, by setting the cover plate 15, the cover plate 15 can be movable relative to the base 10 to cover or open the opening 102. When the home unit 12 is located in the accommodating cavity 100, the cover plate 15 can cover the opening 102. At this time, the third surface 150 of the cover plate 15 is flush with the first surface 101, and the third surface 150 can be used as a partial floor surface of the prefabricated building. The cover plate 15 and the base 10 cooperate to make the floor surface of the prefabricated building more complete. At the same time, the cover plate 15 can prevent the components in the accommodating cavity 100 from falling from the opening 102 during the transportation of the chassis structure 1. When the home unit 12 needs to protrude from the first surface 101 through the opening 102, the cover plate 15 can open the opening 102, so that the home unit 12 can protrude from the first surface 101 through the opening 102. In addition, when the bearing plate 110 and the cover plate 15 are provided at the same time, when the home unit 12 is located in the accommodating cavity 100, the third surface 150 of the cover plate 15 can be used as the floor surface of the prefabricated building at the opening 102 of the base 10, and when the home unit 12 protrudes from the first surface 101 through the opening 102, the second surface 110a of the bearing plate 110 can be used as the floor surface of the prefabricated building at the opening 102 of the base 10. Therefore, no matter what use state the home unit 12 is in, the floor surface of the prefabricated building is relatively complete through the cooperation of the base 10, the bearing plate 110 and the cover plate 15.

[0069] In some embodiments, the size of the cover plate 15 is the same as the size of the opening 102. Thus, when the home unit 12 is located in the accommodating cavity 100, the third surface 150 of the cover plate 15 is flush with the first surface 101 and the cover plate 15 is engaged with the opening 102, so that the first surface 101 and the third surface 150 form a complete surface, further improving the structural and appearance integrity of the first surface 101 and the third surface 150 when used as at least part of the floor surface of the prefabricated building.

[0070] In some embodiments, the chassis structure 1 further includes a second positioning device 16 disposed in the accommodating cavity 100 , and the second positioning device 16 is used to stop the side of the cover plate 15 away from the third surface 150 so that the third surface 150 of the cover plate 15 is flush with the first surface 101 .

[0071] In this way, by setting up the second positioning device 16, during the movement of the cover plate 15, the second positioning device 16 can stop the side of the cover plate 15 away from the third surface 150, so that the third surface 150 of the cover plate 15 is flush with the first surface 101, thereby facilitating the positioning of the third surface 150 of the cover plate 15 when it needs to be flush with the first surface 101, and at the same time can ensure that the cover plate 15 maintains a height at which the third surface 150 is flush with the first surface 101.

[0072] Optionally, the second positioning device 16 may be a positioning block, a fixed latch, a movable latch, a hinge, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0073] Optionally, the first positioning device 14 and the second positioning device 16 can be the same device or two independently arranged devices, which can be selected according to actual conditions and are not specifically limited in this embodiment. When the first positioning device 14 and the second positioning device 16 are the same device, the first positioning device 14 and the second positioning device 16 can be the same movable latch or hinge.

[0074] In some embodiments, the chassis structure 1 also includes a third driver (not shown), which is disposed in the accommodating cavity 100 and connected to the cover 15 . The third driver is used to drive the cover 15 to move relative to the base 10 so that the cover 15 seals or opens the opening 102 .

[0075] In this way, by providing the third driver, it is possible to provide power for the movement of the cover plate 15 relative to the base 10 , thereby enabling the cover plate 15 to close or open the opening 102 .

[0076] Optionally, the third driver may be an electric push rod, a hydraulic push rod, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0077] In some embodiments, the third driver is an electric push rod, the fixed end of the electric push rod is rotatably connected to the base 10, and the movable end of the electric push rod is connected to the cover 15. In this way, the position of the cover 15 relative to the base 10 can be adjusted by extending and retracting the movable end of the electric push rod.

[0078] Optionally, the movable connection mode between the cover plate 15 and the base 10 may be a rotating connection, a sliding connection, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0079] In some embodiments, the cover 15 is rotatably connected to the base 10, and the cover 15 can rotate relative to the base 10 to form a first posture and a second posture relative to the base 10, such as Figure 1 As shown, the first posture is that the cover plate 15 covers the opening 102 and the third surface 150 of the cover plate 15 is flush with the first surface 101, as shown in FIG. Figure 2 As shown, the second posture is that the cover 15 opens the opening 102 and the third surface 150 is inclined to or perpendicular to the first surface 101 . When the cover 15 forms the second posture relative to the base 10 , the cover 15 is located outside the accommodating cavity 100 .

[0080] In this way, the cover plate 15 can be rotated to different positions relative to the base 10 to form a first posture and a second posture. When the cover plate 15 is rotated to cover the opening 102 and the third surface 150 of the cover plate 15 is flush with the first surface 101, the cover plate 15 forms the first posture relative to the base 10. At this time, the third surface 150 of the cover plate 15 is used as the floor surface of the prefabricated building. When the cover plate 15 is rotated to open the opening 102 and the cover plate 15 is located outside the accommodating cavity 100 and the third surface 150 is inclined to or perpendicular to the first surface 101, the cover plate 15 forms the second posture relative to the base 10. At this time, the home unit 12 can protrude from the first surface 101 through the opening 102. In addition, when the cover plate 15 forms the second posture relative to the base 10, the cover plate 15 can also be used as a part of the home unit 12. For example, when the home unit 12 is a bed, the cover plate 15 can be used as the head of the bed. When the home unit 12 is a chair, the cover plate 15 can be used as the backrest of the chair, which further enriches the use function of the cover plate 15.

[0081] In some embodiments, a flexible member 151 is provided on a side of the cover plate 15 facing away from the third surface 150. Thus, when the cover plate 15 forms the second posture relative to the base 10, when the home unit 12 is a bed, the flexible member 151 can be used as a cushion for the head of the bed, and when the home unit 12 is a chair, the flexible member 151 can be used as a backrest cushion for the chair. Optionally, the flexible member 151 can be a silicone pad or a sponge pad, etc., which can be selected according to actual conditions and is not specifically limited in this embodiment.

[0082] In some embodiments, a position sensor 152 is provided on a side of the cover 15 facing away from the third surface 150. When the cover 15 is in the second posture, the position sensor 152 is used to detect the position of the home unit 12 to control the lifting device 11 to drive the home unit 12 to move relative to the base 10 to protrude from the first surface 101.

[0083] In this way, by providing a position sensor 152 on a side of the cover plate 15 away from the third surface 150, when the cover plate 15 is in the second posture, that is, the cover plate 15 is located outside the accommodating cavity 100 and the third surface 150 is inclined to or perpendicular to the first surface 101, the position sensor 152 faces the home unit 12, and can detect the position of the home unit 12 in the height direction of the chassis structure 1, so as to control the lifting device 11 to ensure that the lifting device 11 can drive the home unit 12 to move relative to the base 10 to protrude from the first surface 101. In this embodiment, the position sensor 152 is electrically connected to the control device, and by transmitting the position of the home unit 12 to the control device, the control unit can control the working state of the lifting device 11 to ensure that the lifting device 11 can accurately drive the home unit 12 to move relative to the base 10 to protrude from the first surface 101.

[0084] Optionally, the position sensor 152 may be an infrared sensor or a visual sensor, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0085] Optionally, a position sensor 152 may also be provided on the base 10 to detect the position of the home unit 12 .

[0086] In some embodiments, the chassis structure 1 further includes a control device (not shown), which is electrically connected to the lifting device 11 and the moving device 13 , and is used to control the working states of the lifting device 11 and the moving device 13 .

[0087] In this way, the control device can control the working status of the lifting device 11 and the moving device 13, that is, it can control the height of the mobile home unit 12 of the lifting device 11 and the position of the mobile home unit 12 of the moving device 13, thereby improving the degree of automation of the chassis structure 1 and further facilitating the user to adjust the position of the home unit 12.

[0088] Optionally, the control device for controlling the lifting device 11 and the moving device 13 may be implemented by the same control device or by multiple control devices. The specific selection may be made according to actual conditions and is not specifically limited in this embodiment.

[0089] See also Figure 3 , Figure 3 The dotted lines in the figure indicate the boundaries of different spaces. The second aspect of an embodiment of the present invention discloses an assembled building 2, which includes a building body 20 and a chassis structure 1 as described in the first aspect of the embodiment of the present invention. The building body 20 is connected to the base 10, and the building body 20 and at least a portion of the first surface 101 enclose an indoor space 21. When the mobile device 13 and the home unit 12 protrude from the first surface 101, the mobile device 13 is used to drive the home unit 12 to move to a preset position of the first surface 101 to adjust the position of the home unit 12 relative to the indoor space 21.

[0090] The prefabricated building 2 provided in the second aspect of the embodiment of the present invention adopts the chassis structure 1 provided in the first aspect of the embodiment of the present invention. When the prefabricated building 2 is assembled, the floor surface and the home unit 12 can be installed at the same time by installing the chassis structure 1, and there is no need to transport and install the home unit 12 separately, which further improves the construction efficiency of the prefabricated building 2. The lifting device 11 of the chassis structure 1 can move the home unit 12 relative to the base 10, so that the home unit 12 can be located in the accommodating cavity 100, thereby reducing the overall volume of the chassis structure 1 and facilitating the transportation of the chassis structure 1. The home unit 12 can also be stored in the accommodating cavity 100 when the user does not need to use the home unit 12, thereby saving the indoor space 21 of the prefabricated building 2. The home unit 12 can also be made to protrude from the first surface 101 through the opening 102 opened on the base 10, so that the user can use the home unit 12. When the home unit 12 is moved to the position protruding from the first surface 101 by the lifting device 11 through the moving device 13 of the chassis structure 1, the home unit 12 can be brought to the preset position of the first surface 101 by the moving device 13, so that the user can adjust the position of the home unit 12 when the prefabricated building 2 is used. In addition, since the chassis structure 1 can be provided with multiple home units 12, and the positions of the multiple home units 12 can be adjusted separately, the user can flexibly allocate the home units 12 required for use in the prefabricated building 2, store the home units 12 that are not needed in the accommodating cavity 100, and can also adjust the positions of each home unit 12, thereby improving the flexibility of the prefabricated building 2.

[0091] Optionally, the chassis structure 1 can be directly used as the floor of the prefabricated building 2. During assembly, the wall panels and other structures of the prefabricated building 2 can be directly installed on the chassis structure 1. The chassis structure 1 can also be set on the floor of the prefabricated building 2 for use. A groove can also be opened on the floor of the prefabricated building 2, and the chassis structure 1 can be buried in the groove for use. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0092] In some embodiments, the indoor space 21 includes multiple functional spaces 210, the number of preset positions is multiple, and the multiple preset positions are at least partially located in different functional spaces 210. The mobile device 13 is used to drive the home unit 12 to move to the multiple preset positions on the first surface 101, so that the home unit 12 moves to different functional spaces 210.

[0093] In this way, by dividing the indoor space 21 into multiple functional spaces 210 (such as kitchen space, bedroom space, living room space, bathroom space, etc.), the user can move the home unit 12 to different functional spaces 210 for use through the mobile device 13 according to needs, such as moving the bed originally located in the bedroom space to the living room space for use, and moving the bathtub originally located in the bathroom space to the living room space for use, etc., thereby improving the flexibility of use of the home unit 12.

[0094] In some embodiments, the first surface 101 includes a first part 101a and a second part 101b, the building body 20 and the first part 101a enclose an indoor space 21, and the second part 101b forms an outdoor space 22. There are multiple preset positions, some of which are located in the first part 101a, and some of which are located in the second part 101b. The mobile device 13 is used to drive the home unit 12 to move to multiple preset positions on the first surface 101, so that the home unit 12 moves to the indoor space 21 or the outdoor space 22.

[0095] In this way, by dividing the first surface 101 into a first part 101a and a second part 101b, the building body 20 and the first part 101a are enclosed to form an indoor space 21, and the space above the second part 101b forms an outdoor space 22 (the outdoor space 22 can be used as a balcony, garden, etc. of the prefabricated building 2). The user can move the home unit 12 to the indoor space 21 or the outdoor space 22 for use through the mobile device 13 as needed. For example, a user can move the bathtub originally located in the indoor space 21 to the outdoor space 22 for use, and another user can move the bathtub moved to the outdoor space 22 back to the indoor space 21 for use, thereby meeting the usage needs of different users.
