[0031] The present invention discloses a chassis structure and an assembled building that are easy to construct. A home unit is integrated into the chassis structure. When applied to an assembled building, there is no need to manually carry the home unit separately. The time taken to put the assembled building into use is shorter, thus saving time and labor.

[0032] Embodiment 1

[0033] See also Figure 1 and Figure 2 , is a structural schematic diagram of a chassis structure 100 provided in Embodiment 1 of the present invention. The chassis structure 100 is applied to prefabricated buildings. The chassis structure 100 includes a base 10 and a home module 11. The base 10 has a first surface 10a and a receiving cavity 10b. The first surface 10a is used to form the surface of the floor of the prefabricated building. The home module 11 is arranged in the receiving cavity 10b. The home module 11 includes a plurality of movably arranged home units 111. Each home unit 111 is used to be movable to be located in the receiving cavity 10b or on the first surface 10a.

[0034] in, Figure 1 The home unit 111 is shown to be moved to the accommodation cavity 10b. Figure 2 It is shown that a part of the home unit 111 is moved to be located on the first surface 10a.

[0035] In this embodiment, the home module 11 is arranged through the accommodating cavity 10b of the base 10. The home module 11 includes a plurality of movably arranged home units 111. The home units 111 are movably located in the accommodating cavity 10b or on the first surface 10a of the base 10. In this way, on the one hand, during the transportation and installation process of the chassis structure 100, the home units 111 can be accommodated in the accommodating cavity 10b to protect the home units 111, and the damage to the home units 111 caused by collision can be avoided. The space occupied by the home units 111 can also be reduced, thereby reducing the overall volume of the chassis structure 100 and reducing the difficulty of transporting the chassis structure 100. On the other hand, when the chassis structure 100 is put into use, the home units 111 not used by the user can be accommodated in the accommodating cavity 10b to increase the area of ​​the vacant area of ​​the first surface 10a, and the home units 111 used by the user can be placed on the first surface 10a, so that the user can use the home units 111 normally. Based on this, the chassis structure 100 is applied to prefabricated buildings. The chassis structure 100 integrated with the home unit 111 can be transported to the site as a whole for direct installation, and the transportation difficulty is relatively low. At the same time as the prefabricated building is installed, the home unit 111 can be brought into the site, and there is no need to manually carry the home unit 111 separately. The first surface 10a of the base 10 is used to form the surface of the floor of the prefabricated building. The home unit 111 can be arranged by placing it on the first surface 10a, shortening the time spent on putting the prefabricated building into use, saving time and effort. In addition, by moving different home units 111 to the first surface 10a for use, the use mode of the space of the prefabricated building is changed.

[0036] Specifically, the chassis structure 100 can be pre-buried in the ground, or added to a terrace, an open space, etc., and the prefabricated building can be installed using the chassis structure 100 as the base of the prefabricated building.

[0037] The home unit 111 refers to products that can be used by users in daily life in prefabricated buildings, including but not limited to furniture, household appliances, sanitary ware, fitness equipment, energy storage equipment, purification equipment, water supply equipment, sewage treatment equipment, etc., which are not specifically limited in this embodiment. If the home unit 111 includes water supply equipment and sewage treatment equipment, the chassis structure 100 can be used in environments lacking municipal water supply and drainage points, such as suburbs, forests, deserts, etc.

[0038] As an optional embodiment, the home module 11 includes a plurality of home units 111 of different categories. In this way, the user can move the home units 111 of the required category to the first surface 10a for use according to the use requirements, and move the home units 111 of the unnecessary category to the accommodating cavity 10b for hiding. In addition, by moving the home units 111 of the same category to the first surface 10a, or emptying the home units 111 of the first surface 10a (i.e., hiding in the accommodating cavity 10b), a single functional area of ​​the category can be constructed in a certain area of ​​the first surface 10a, and by moving the home units 111 of different categories to the first surface 10a, multiple multifunctional areas can be constructed in a certain area of ​​the first surface 10a. Based on this, when the chassis structure 100 is applied to an assembled building, the space of the assembled building corresponding to the single functional area is a single functional space, and the multifunctional area corresponds to a multifunctional space, and the single functional space and the multifunctional space have corresponding usage modes, such as bedroom mode, meditation mode, meeting and gathering mode, sports mode, etc.

[0039] Exemplarily, a plurality of different types of home furnishing units 111 include at least residential home furnishing units and bathroom home furnishing units. Thus, when the residential home furnishing unit is moved to the first surface 10a, the single functional area is the residential functional area, and the single functional space is the residential functional space. When the bathroom home furnishing unit is moved to the first surface 10a, the single functional area is the bathroom functional area, and the single functional space is the bathroom functional space. When the residential home furnishing unit and the bathroom home furnishing unit are moved to the first surface 10a, the multifunctional area is the residential-bathroom functional area, and the multifunctional space is the residential-bathroom functional space. For example, the user can take a bath in the bathtub while watching TV, or move the yoga mat and the audio equipment to the first surface 10a, then the multifunctional area is the sports-living functional area, and the multifunctional space is the sports-living functional space. For example, the user can use the yoga mat to exercise while using the audio equipment to listen to music. When the home furnishing unit 111 on the first surface 10a is emptied, the single functional area can be the meditation functional area, and the single functional space is the meditation functional space.

[0040] Among them, residential home units include but are not limited to beds, sofas, tables and chairs, air supply and exhaust systems, baseboard hot and cold radiation systems, electrical equipment (home appliances, lighting), etc., and bathroom home units include toilets, bathtubs, bars, washing and drying machines, fresh water storage tanks, sewage storage tanks, sewage treatment equipment, energy storage equipment, rainwater collection and purification equipment, etc., and this embodiment does not make specific limitations on this.

[0041] In some other embodiments, functional areas and functional spaces such as an oxygen bar and a stage can be formed according to the types or the presence or absence of the home unit 111 on the first surface 10a.

[0042] Optionally, multiple home units 111 of different categories may also include sports home units 111 and courtyard home units 111, and the sports home units 111 may include yoga mats, treadmills, dumbbells, barbells, comprehensive training equipment gantry frames, etc., and the courtyard home units 111 include swings, parasols, tables and chairs, etc. This embodiment does not make specific limitations on this.

[0043] As another optional embodiment, the chassis structure 100 includes a plurality of home furnishing modules 11 of different categories, and the plurality of home furnishing modules 11 are arranged at intervals in the accommodating cavity 10b, and each home furnishing module 11 includes a plurality of home furnishing units 111 of the same category. In this way, by providing a plurality of home furnishing modules 11 of different categories, the user's use requirements for different functions can be met, and each home furnishing module 11 integrates a plurality of home furnishing units 111 of the same category, which is convenient for the user to construct a single functional area in a smaller area of ​​the first surface 10a, and the plurality of home furnishing units 111 of the same category are close to each other, which is more convenient for the user to use.

[0044] Exemplarily, a plurality of different types of home furnishing modules 11 include at least a residential home furnishing module 11a and a bathroom home furnishing module 11b, wherein the residential home furnishing module 11a includes a plurality of residential home furnishing units, and the bathroom home furnishing module 11b includes a plurality of bathroom home furnishing units. In this way, when the user moves a plurality of residential home furnishing units to the first surface 10a, the plurality of residential home furnishing units can construct a residential functional area in a smaller area of ​​the first surface 10a. For example, the user can use a bed, a bedside lamp and a dressing table in a smaller area, do skin care before going to bed on the dressing table, use the bedside lamp to read, watch mobile phones and other electronic products when going to bed, and turn off the bedside lamp before going to bed, and go to sleep directly on the bed. Alternatively, the user can use a sofa and a TV in a smaller area, so as to watch the TV while sitting on the sofa. By analogy, the use of the bathroom home furnishing module 11b can refer to the residential home furnishing module 11a, which will not be described one by one here.

[0045] In some other embodiments, multiple different categories of home modules 11 may also include a sports home module (not shown) and a courtyard furniture module (not shown). The sports home module includes multiple sports home units 111, and the courtyard furniture module includes multiple courtyard home units 111. This embodiment does not make any specific limitations on this.

[0046] In some embodiments, the chassis structure 100 further includes a rotating seat 12, which is located on the side of the base 10 away from the first surface 10a. The base 10 is rotatably connected to the rotating seat 12, and the base 10 can rotate relative to the rotating seat 12 around a straight line a perpendicular to the first surface 10a. In this way, by rotating the base 10 relative to the rotating seat 12 around a straight line a perpendicular to the first surface 10a, the orientation of the base 10 can be changed, and the orientation of the home unit 111 can be changed at the same time. Based on this, when the chassis structure 100 is applied to an assembled building, the change in the orientation of the base 10 can drive the change in the overall orientation of the assembled building. For example, by adjusting the overall orientation of the assembled building, it can adapt to sunrise and sunset, and provide users with sunlight that meets their needs.

[0047] Exemplarily, the chassis structure 100 further includes a driving device (not shown), which is connected to the rotating seat 12 and the base 10, and is used to drive the base 10 to rotate relative to the rotating seat 12 around a straight line a perpendicular to the first surface 10a. In this way, the base 10 and the home unit 111 can be automatically changed in orientation by driving the base 10 to rotate relative to the base 10 around a straight line a perpendicular to the first surface 10a through the driving device, and the degree of automation is high.

[0048] Optionally, the driving device may be a motor or an annular slide rail and a slider structure, for example, a motor is directly used to drive the base 10 to rotate relative to the rotating seat 12, or an annular slide rail and a slider are set between the base 10 and the rotating seat 12, and the slider is used to slide along the annular slide rail to drive the base 10 to rotate relative to the rotating seat 12. This embodiment does not make any specific restrictions on this.

[0049] In some embodiments, the home module 11 further includes a moving device (not shown), which is used to move the home unit 111 to the accommodation cavity 10b or the first surface 10a. In this way, when the user uses the home unit 111, the home unit 111 can be moved to the first surface 10a through the moving device, and when the user does not need to use the home unit 111, the home can be moved to the accommodation cavity 10b through the moving device, thereby hiding the home unit 111, and the degree of automation is high.

[0050] Exemplarily, the moving device includes a lifting device (not shown), which is disposed in the accommodating cavity 10b, and is used to carry the home unit 111, and is used to move the home unit 111 along a direction x perpendicular to the first surface 10a to the accommodating cavity 10b or the first surface 10a. In this way, when the user uses the home unit 111, the home unit 111 can be moved along the direction x perpendicular to the first surface 10a to the first surface 10a through the lifting device, and when the user does not need to use the home unit 111, the home can be moved along the direction x perpendicular to the first surface 10a to the accommodating cavity 10b through the lifting device, thereby realizing the hiding of the home unit 111, and the degree of automation is relatively high.

[0051] Optionally, the lifting device may include one or more of a jack, an electric push rod, a scissor mechanism, etc., which can be selected according to actual conditions and is not specifically limited in this embodiment.

[0052] In some embodiments, Figure 3 As shown, the moving device also includes a translation device (not shown), which is used to move the home unit 111 to a preset position on the first surface 10a when the home unit 111 is located on the first surface 10a. In this way, by moving the home unit 111 to the preset position on the first surface 10a through the translation device, the use position of the home unit 111 on the first surface 10a can be changed, so that the user can use the furniture unit in different spaces of the prefabricated building, and the degree of automation is relatively high.

[0053] in, Figure 3 The home unit 111 is shown to be moved to a preset position on the first surface 10a.

[0054] Optionally, the moving device may include one or more of an electric wheel, a guide rail slider mechanism, a push rod mechanism, a magnetic suspension mechanism, etc., which can be selected according to actual conditions and are not specifically limited in this embodiment.

[0055] The first embodiment of the present invention provides a chassis structure 100, in which a home module 11 is arranged through a receiving cavity 10b of a base 10, and the home module 11 includes a plurality of movably arranged home units 111, and the home units 111 are movably located in the receiving cavity 10b or on the first surface 10a of the base 10. In this way, on the one hand, during the transportation and installation process of the chassis structure 100, the home units 111 can be accommodated in the receiving cavity 10b, and the home units 111 can be protected, and the damage to the home units 111 caused by collision can be avoided, and the space occupied by the home units 111 can be reduced, thereby reducing the overall volume of the chassis structure 100 and reducing the difficulty of transportation of the chassis structure 100. On the other hand, when the chassis structure 100 is put into use, the home units 111 not used by the user can be accommodated in the receiving cavity 10b, thereby increasing the area of ​​the vacant area of ​​the first surface 10a, and the home units 111 used by the user can be placed on the first surface 10a, so that the user can use the home units 111 normally. Based on this, the chassis structure 100 is applied to prefabricated buildings. The chassis structure 100 integrated with the home unit 111 can be transported to the site as a whole for direct installation, and the transportation difficulty is relatively low. At the same time as the prefabricated building is installed, the home unit 111 can be brought into the site, and there is no need to manually carry the home unit 111 separately. The first surface 10a of the base 10 is used to form the surface of the floor of the prefabricated building, and the home unit 111 can be placed on the surface to achieve the arrangement of the home unit 111, shortening the time spent on putting the prefabricated building into use, saving time and labor. In addition, by moving different home units 111 to the first surface 10a for use, the use mode of the space of the prefabricated building is changed.

[0056] Embodiment 2

[0057] See also Figure 4 , which is a structural schematic diagram of an assembled building 200 provided in the second embodiment of the present invention. The assembled building 200 includes a building body 20 and the chassis structure 100 of the first embodiment. The building body 20 is connected to the base 10, and the building body 20 and at least a portion of the first surface 10a of the base 10 enclose an indoor space 201.

[0058] In this embodiment, the building body 20 is connected to the base 10, and the indoor space 201 is enclosed by the building body 20 and at least a portion of the first surface 10a of the base 10. In this way, when the home unit is moved to the portion of the first surface 10a corresponding to the indoor space 201, the home unit can be used by the user in the indoor space 201, and when the home unit is moved to the portion of the first surface 10a outside the indoor space 201, the home unit can be used by the user outside the indoor space 201, for example, the home unit is located in the outdoor space.

[0059] In some embodiments, the indoor space 201 includes a plurality of subspaces arranged at intervals, and different types of home furnishing modules 11 are arranged at the positions of the subspaces corresponding to the accommodating cavity 10b along the direction x perpendicular to the first surface 10a. In this way, by dividing the indoor space 201 into a plurality of subspaces, each subspace corresponds to a different type of home furnishing module 11, and thus, by moving the home furnishing unit corresponding to the home furnishing module 11 from the accommodating cavity 10b to the first surface 10a along the direction x perpendicular to the first surface 10a, the home furnishing unit corresponding to the home furnishing module 11 can make the corresponding subspace form a corresponding functional space, for example, the subspace corresponding to the residential home furnishing module 11a forms a residential functional space 201a, and the subspace corresponding to the bathroom home furnishing module 11b forms a bathroom functional space 201b. In addition, by moving the residential home furnishing unit of the residential home furnishing module 11a located in the residential functional space 201a to the bathroom functional space 201b, the use mode of the original residential functional space 201a can be changed from the residential mode to the bathroom mode, and the corresponding subspace becomes the bathroom functional space 201b.

[0060] Among them, the bathroom functional space 201b can also change its usage mode by moving the home units corresponding to different types of home modules 11, turning it into other single functional spaces, or turning it into a multi-functional space, which will not be elaborated here.

[0061] The second embodiment of the present invention provides an assembled building 200, which integrates the home unit into the chassis structure 100. There is no need to manually carry the home unit separately. The assembled building 200 takes a shorter time to be put into use, saving time and labor.
