DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0047] Please also read Figures 1 to 3In a first aspect, an embodiment of the present invention discloses a chassis structure 1 with an adjustable position of a household water unit 12, which is applied to an assembled building. The chassis structure 1 includes a base 10, a household water unit 12, an active module 11 and a water supply and drainage module 13. The base 10 has a first surface 101, and the first surface 101 is used to form at least a part of the floor surface of the assembled building. The active module 11 is arranged on the base 10, and the active module 11 is used to carry the household water unit 12, and is used to drive the water-using household water unit to move to any one of a plurality of preset positions on the first surface 101. The water supply and drainage module 13 is arranged on the base 10, and the water supply and drainage module 13 is connected to the household water unit 12. The water supply and drainage module 13 is used to supply water to the household water unit 12 and receive water discharged from the household water unit 12.

[0048] The first aspect of the embodiment of the present invention provides a chassis structure 1 with an adjustable position of a household water unit 12, wherein the household water unit 12 is preset on a base 10, and a first surface 101 of the base 10 can be used as at least a portion of the floor surface of the prefabricated building. By installing the chassis structure 1 on the prefabricated building, the installation of the floor bottom surface of the prefabricated building and the household water unit 12 is completed at the same time, and there is no need to transport and install the household water unit 12 separately, thereby further improving the construction efficiency of the prefabricated building. Furthermore, through the movable module 11, the household water unit 12 can be driven to move relative to the base 10 to any one of the multiple preset positions of the first surface 101, which can facilitate the user to flexibly adjust the position of the household water unit 12 when the prefabricated building is in use. At the same time, by providing the water supply and drainage module 13, on the one hand, it can ensure that when the household water unit 12 is moved to different preset positions, it can still supply water to the household water unit 12 and receive water discharged from the household water unit 12, thereby ensuring that the household water unit 12 can be used normally when adjusted to any preset position. On the other hand, it ensures that the water supply and drainage needs of the household water unit 12 can be guaranteed in any environment (such as suburbs, forests, etc. that are not convenient for connecting with the city's water supply and drainage system), thereby improving the flexibility of the construction environment of the prefabricated building.

[0049] Optionally, the household water unit 12 may be bathroom appliances (such as bathtubs, toilets, etc.), kitchen appliances (such as kitchen sinks, bar counters, etc.), furniture (such as coffee tables, etc.), electrical appliances (such as washing machines, water heaters, etc.), etc., which are products for daily use by users in prefabricated buildings and require water supply and drainage. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0050] Optionally, the base 10 may be a block structure, a shell structure or a box structure, etc., which can be selected according to actual conditions and is not specifically limited in this embodiment.

[0051] Optionally, the number of the household water units 12 and the number of the movable modules 11 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 household water units 12 is multiple, the number of the movable modules 11 can also be one, so as to achieve the position adjustment of multiple household water units 12 at the same time, and the number of the movable modules 11 can also be multiple and correspond to the household water units 12 one by one, so as to achieve the position adjustment of multiple household water units 12 respectively.

[0052] In some embodiments, the water supply and drainage module 13 includes a water storage device 130 and a connection structure 131. The water storage device 130 is disposed on the base 10. The water storage device 130 is used to supply water to the household water unit 12 and receive water discharged from the household water unit 12. The connection structure 131 is connected to the water storage device 130; Figure 5 and Figure 7 As shown, when the household water unit 12 moves, the household water unit 12 drives part of the connection structure 131 to move, so that the household water unit 12 is connected to the connection structure 131, or, as shown in FIG. Figures 1 to 4 As shown, when the household water unit 12 moves to a preset position on the first surface 101 , the household water unit 12 is connected to the connection structure 131 .

[0053] In this way, when the household water unit 12 moves, the connecting structure 131 of the first scheme can move along with the movement of the household water unit 12 under the drive of the household water unit 12, so that the household water unit 12 can maintain communication with the connecting structure 131 during any movement. Alternatively, the connecting structure 131 of the second scheme can achieve communication with the household water unit 12 when the household water unit 12 moves to a preset position of the first surface 101, that is, the household water unit 12 can achieve communication with the connecting structure 131 when it moves to any preset position. By setting the connecting structure 131 of any of the two schemes, it is possible to ensure that the household water unit 12 is connected to the connecting structure 131 at any preset position, thereby achieving communication with the water storage device 130 through the connecting structure 131, ensuring that the water storage device 130 can supply water to the household water unit 12 and receive water discharged from the household water unit 12, thereby ensuring the normal use of the household water unit 12 at any preset position.

[0054] Optionally, the water supply and drainage module 13 can be directly disposed on the surface of the base 10 (such as the first surface 101), or can be disposed in the internal space of the base 10. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0055] In some embodiments, the base 10 has a receiving cavity 100 , and the water supply and drainage module 13 is disposed in the receiving cavity 100 .

[0056] In this way, by arranging the water supply and drainage module 13 in the accommodating cavity 100 of the base 10, the water supply and drainage module 13 can be hidden in the base 10, saving the indoor space of the prefabricated building and improving the aesthetics of the indoor space of the prefabricated building.

[0057] In some embodiments, the base 10 is provided with an opening 102 passing through the first surface 101, and the opening 102 is connected to the accommodating cavity 100. The movable module 11 includes a lifting device 110 and a moving device 111. The lifting device 110 is provided in the accommodating cavity 100. The lifting device 110 is used to carry the household water unit 12, and is used to drive the household water unit 12 to move relative to the base 10 so that the household water unit 12 is located in the accommodating cavity 100, or so that the household water unit 12 protrudes from the first surface 101 through the opening 102. The moving device 111 is provided at the household water unit 12. The moving device 111 is used to drive the household water unit 12 to move to any one of a plurality of preset positions on the first surface 101 when the household water unit 12 protrudes from the first surface 101.

[0058] In this way, the household water unit 12 can be moved relative to the base 10 by the lifting device 110, so that the household water unit 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, the household water unit 12 can be stored in the accommodating cavity 100 when the user does not need to use the household water unit 12, saving the indoor space of the prefabricated building, and the household water 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 household water unit 12. At the same time, by setting the moving device 111, when the household water unit 12 is moved to the position protruding from the first surface 101 by the lifting device 110, the household water unit 12 can be brought to the preset position of the first surface 101 by the moving device 111, which can facilitate the user to call the position of the water-saving household unit when the prefabricated building is used.

[0059] Optionally, the lifting device 110 may be a push rod mechanism or a scissors mechanism, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0060] Optionally, the moving device 111 may include one or more of wheels, guide rail slider mechanisms, push rod mechanisms, etc., which can be selected according to actual conditions and are not specifically limited in this embodiment.

[0061] Please also read Figures 1 to 3In some embodiments, the water supply and drainage module 13 includes a water storage device 130 and a connecting structure 131. The water storage device 130 is arranged in the accommodating cavity 100. The connecting structure 131 includes a connecting hole 1310 and a third pipe 1311. A plurality of connecting holes 1310 are arranged on the first surface 101 and connected to the accommodating cavity 100. Each connecting hole 1310 is arranged corresponding to each preset position. One end of the third pipe 1311 is connected to the water storage device 130, and the other end of the third pipe 1311 is connected to the plurality of connecting holes 1310. The water storage device 130 is used to store water, and to supply water to the household water unit 12 through the connecting hole 1310 and the third pipe 1311 and to receive water discharged from the household water unit 12. The connecting hole 1310 is used to connect the connecting hole 1310 corresponding to any preset position with the household water unit 12 when the household water unit 12 moves to any one of the plurality of preset positions on the first surface 101.

[0062] In this way, by setting a plurality of connection holes 1310 on the first surface 101, and the position of each connection hole 1310 corresponds to each preset position, when the water-using household unit moves to any of the plurality of preset positions on the first surface 101, it can be connected with the connection hole 1310 at the preset position, and the plurality of connection holes 1310 are connected with the water storage device 130 through the third pipe 1311, thereby realizing the connection between the household water-using unit 12 and the water storage device 130 at any preset position, ensuring that the water storage device 130 can supply water to the household water-using unit 12 and receive the water discharged by the household water-using unit 12, thereby ensuring the normal use of the household water-using unit 12 at any preset position. In addition, the water storage device 130 and the third pipe 1311 are both arranged in the accommodating cavity 100 of the base 10, which can reduce the occupation of the indoor space of the prefabricated building by the chassis structure 1, and at the same time improve the neatness of the appearance of the chassis structure 1.

[0063] In some embodiments, the third pipeline 1311 includes a main pipeline 1311a and multiple branch pipelines 1311b connected to the main pipeline 1311a, the main pipeline 1311a is connected to the water storage device 130, and each branch pipeline 1311b is respectively connected to each connecting hole 1310, and each branch pipeline 1311b is provided with a valve 1311c, and the valve 1311c is used to control the connection and disconnection of the corresponding branch pipeline 1311b and the main pipeline 1311a.

[0064] In this way, the main pipeline 1311a of the third pipeline 1311 is simultaneously connected to multiple connecting holes 1310 through multiple branch pipelines 1311b, and by providing a valve 1311c in each branch pipeline 1311b, when the household water unit 12 is connected to one of the connecting holes, the valve 1311c in the branch pipeline 1311b connected to the connecting hole connected to the household water unit 12 is opened, and the other valves 1311c are closed, thereby ensuring the connection between the household water unit 12 and the water storage device 130, and preventing water from leaking from the connecting holes 1310 that are not in use.

[0065] Optionally, the valve 1311c can be a manual valve or a solenoid valve, etc., which can be selected according to actual conditions. Preferably, the valve 1311c is selected as a solenoid valve to improve the degree of automation when the chassis structure 1 is used and improve the user experience.

[0066] See also Figure 4 In some embodiments, the water supply and drainage module 13 includes a water storage device 130 and a connecting structure 131. The water storage device 130 is arranged on the base 10. The connecting structure 131 includes a plurality of connecting holes 1310 and a third pipe 1311. The plurality of connecting holes 1310 are arranged on the first surface 101 and connected to the accommodating cavity 100. Each connecting hole 1310 is arranged corresponding to a preset position. One end of the third pipe 1311 is connected to the water storage device 130. The other end of the third pipe 1311 can be movably arranged to be connected to any one of the plurality of connecting holes 1310. The water storage device 130 is used to store water, and to supply water to the household water unit 12 through the connecting holes 1310 and the third pipe 1311 and to receive water discharged from the household water unit 12.

[0067] In this way, by setting a plurality of connecting holes 1310 on the first surface 101, and the position of each connecting hole 1310 corresponds to each preset position, when the household water-using unit moves to any one of the plurality of preset positions on the first surface 101, it can be connected with the connecting hole 1310 at the preset position, and one end of the third pipe 1311 is connected with the water storage device 130, and the other end of the third pipe 1311 is in a movable state, and the position of the other end of the third pipe 1311 can be freely adjusted so that it is connected with the connecting hole 1310 connected with the household water-using unit 12, thereby realizing the connection between the household water-using unit 12 and the water storage device 130 at any preset position, ensuring that the water storage device 130 can supply water to the household water-using unit 12 and receive water discharged from the household water-using unit 12, thereby ensuring the normal use of the household water-using unit 12 at any preset position. In addition, the water storage device 130 and the third pipe 1311 are both arranged in the accommodating cavity 100 of the base 10, which can reduce the occupation of the indoor space of the prefabricated building by the chassis structure 1 and improve the neatness of the appearance of the chassis structure 1.

[0068] In some embodiments, the water supply and drainage module 13 also includes a first driving device 132, which is disposed in the accommodating cavity 100, and is connected to one movably disposed end of the third pipe 1311. The first driving device 132 is used to drive the movably disposed end of the third pipe 1311 so that the third pipe 1311 is connected to any one of the multiple connecting holes 1310.

[0069] In this way, by providing the first driving device 132, when the water-using household unit moves to any one of the multiple preset positions of the first surface 101, the first driving device 132 can provide power for the movement of the other end of the third pipe 1311, so that the other end of the third pipe 1311 is connected to the connecting hole 1310 connected to the household water unit 12, thereby improving the automation of the chassis structure 1. In addition, the first driving device 132 is also arranged in the accommodating cavity 100 of the base 10, which can reduce the occupation of the indoor space of the prefabricated building by the chassis structure 1, and at the same time improve the neatness of the appearance of the chassis structure 1.

[0070] Optionally, the first driving device 132 may be a linear drive, a manipulator, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0071] In some embodiments, the third pipe 1311 is configured to be deformable to change its length, or the water supply and drainage module 13 further includes a rotating member 133 (see Figure 5 ), the rotating member 133 can be rotatably disposed in the accommodating chamber 100, and the third pipe 1311 surrounds the rotating member 133. The rotating member 133 is used to rotate relative to the accommodating chamber 100 to receive or release the third pipe 1311.

[0072] In this way, the first solution is to deform the third pipe 1311 itself so that its length can be changed (for example, the third pipe 1311 is a corrugated pipe or a flexible pipe, etc., which can achieve the effect of deforming to change its own length), so that the third pipe 1311 can be deformed under the drive of the first driving device 132 and connected with different connecting holes 1310 according to the position of the household water unit 12. The second solution is to wrap the third pipe 1311 of sufficient length around the rotating member 133, and the rotating member 133 can be rotated to wind it. The third pipe 1311 is stored in the rotating member 133, thereby reducing the length of the portion of the third pipe 1311 that is not wrapped around the rotating member 133. The rotating member 133 can also release the wound third pipe 1311, thereby increasing the length of the portion of the third pipe 1311 that is not wrapped around the rotating member 133. Therefore, under the drive of the first driving device 132, the third pipe 1311 can extend to different lengths relative to the rotating member 133 and communicate with different connecting holes 1310 according to the position of the household water unit 12. Either of the two solutions can achieve the communication between the household water unit 12 and the third pipe 1311 at any preset position, ensuring the normal use of the household water unit 12 at any preset position.

[0073] See also Figure 5 , Figure 5 The dotted line in the figure indicates the setting position of the first pipe 1312. In some embodiments, the water supply and drainage module 13 includes a water storage device 130 and a connecting structure 131. The water storage device 130 is arranged on the base 10. The connecting structure 131 includes a rotating member 133 and a first pipe 1312. The rotating member 133 is rotatably arranged on the base 10. The first pipe 1312 surrounds the rotating member 133. One end of the first pipe 1312 is connected to the water storage device 130, and the other end of the first pipe 1312 is connected to the household water unit 12. The rotating member 133 is used to rotate relative to the base 10 to store or release the first pipe 1312. The water storage device 130 is used to store water, and is used to supply water to the household water unit 12 through the first pipe 1312 and receive water discharged from the household water unit 12.

[0074] In this way, one end of the first pipe 1312 is connected to the water storage device 130, and the other end of the first pipe 1312 is connected to the household water unit 12. When the household water unit 12 moves at any position on the first surface 101, one end of the first pipe 1312 can follow the movement of the household water unit 12. By setting the rotating member 133, when the household water unit 12 moves to a farther position, the rotating member 133 is driven by the household water unit 12 to rotate and be pulled out through the first pipe 1312 wound on the rotating member 133, thereby increasing the length of the portion of the first pipe 1312 that is not wrapped around the rotating member 133. When the household water unit 12 moves to a closer position, the rotating member 133 rotates. The third pipe 1311 can be wound to accommodate the first pipe 1312 in the rotating member 133, thereby reducing the length of the portion of the first pipe 1312 that is not wrapped around the rotating member 133, so that by changing the length of the portion of the first pipe 1312 that is not wrapped around the rotating member 133 (i.e., the length of the freely movable portion), the end of the first pipe 1312 that is connected to the household water unit 12 can move with the household water unit 12, ensuring that the household water unit 12 can be connected to the first pipe 1312 at any position of the first surface 101, ensuring the normal use of the household water unit 12 at any position of the first surface 101, and further improving the flexibility of the position layout of the household water unit 12. In addition, the structure of the water supply and drainage module 13 of this embodiment is relatively simple, which can reduce the difficulty of production and assembly of the chassis structure 1, and at the same time reduce the production cost of the chassis structure 1.

[0075] Please also read Figure 5 and Figure 6 In some embodiments, the chassis structure 1 further includes a guide member 134, which is distributed along a plurality of preset positions. The guide member 134 is disposed on the first surface 101, and the guide member 134 has a guide groove 1341. When the movable module 11 drives the water-using home unit to move on the first surface 101, the portion of the first pipe 1312 located outside the accommodating cavity 100 moves along the guide groove 1341.

[0076] In this way, when the movable module 11 drives the household water unit 12 to move on the first surface 101, the portion of the first pipe 1312 that is pulled out of the rotating member 133 will move relatively irregularly. By providing a guide member 134 with a guide groove 1341, and the guide member 134 is arranged along the distribution of multiple preset positions (that is, it can cover the preset position or be arranged beside the preset position), the first pipe 1312 can be moved at least partially along the guide groove 1341, so that the movement of the first pipe 1312 is relatively regular, and the irregular movement of the portion of the first pipe 1312 located outside the accommodating cavity 100 is avoided, which affects the neatness of the appearance of the chassis structure 1 and affects the user experience.

[0077] Preferably, the opening of the guide member 134 faces the household water unit 12. In this way, when the household water unit 12 moves, the portion of the first pipe 1312 pulled out of the rotating member 133 can be hidden in the guide member 134, further improving the neatness of the appearance of the chassis structure 1 and ensuring the safety of the first pipe 1312.

[0078] In some embodiments, the base 10 has a accommodating cavity 100, the water storage device 130 is disposed in the accommodating cavity 100, the rotating member 133 can be rotatably disposed in the accommodating cavity 100, the first surface 101 of the base 10 is provided with a first through hole 103, and the guide member 134 is provided with a second through hole 1342 on the side facing the first surface 101, the second through hole 1342 is connected to the guide groove 1341 and the first through hole 103, and the other end of the first pipe 1312 passes through the first through hole 103 and the second through hole 1342 to be connected to the household water unit 12.

[0079] In this way, by arranging the water storage device 130 and the rotating member 133 in the accommodating cavity 100 of the base 10, the occupation of the indoor space of the prefabricated building by the chassis structure 1 can be reduced, while the neatness of the appearance of the chassis structure 1 is improved. At the same time, part of the first pipe 1312 is also hidden in the accommodating cavity 100, and the part outside the accommodating cavity 100 can be blocked by the guide member 134, which further improves the neatness of the appearance of the chassis structure 1 and the safety of use of the first pipe 1312.

[0080] See also Figure 7 , Figure 7 The dotted line in the figure indicates the setting position of the second pipe 1313. In some embodiments, the water supply and drainage module 13 includes a water storage device 130 and a connecting structure 131. The water storage device 130 is arranged on the base 10. The connecting structure 131 includes a second pipe 1313. One end of the second pipe 1313 is connected to the water storage device 130, and the other end of the second pipe 1313 is connected to the household water unit 12. The second pipe 1313 is configured to be deformable to change its own length so as to move with the household water unit 12. The water storage device 130 is used to store water, and to supply water to the household water unit 12 through the second pipe 1313 and receive water discharged from the household water unit 12.

[0081] In this way, one end of the second pipe 1313 is connected to the water storage device 130, and the other end of the second pipe 1313 is connected to the household water unit 12. When the household water unit 12 moves at any position on the first surface 101, by configuring the second pipe 1313 to be deformable to change its own length (for example, the second pipe 1313 is a corrugated pipe or a flexible pipe, etc., the effect of deforming to change its own length can be achieved), so that the end of the second pipe 1313 connected to the household water unit 12 can follow the movement of the household water unit 12 and the second pipe 1313 is deformed at the same time, ensuring that the household water unit 12 can be connected to the second pipe 1313 when it moves to any position on the first surface 101, ensuring the normal use of the household water unit 12 at any position on the first surface 101, and further improving the flexibility of the position layout of the household water unit 12. In addition, the structure of the water supply and drainage module 13 of this embodiment is relatively simple, which can reduce the difficulty of production and assembly of the chassis structure 1, and reduce the production cost of the chassis structure 1.

[0083] In this way, by arranging the water storage device 130 in the accommodating cavity 100 of the base 10, the occupation of the indoor space of the prefabricated building by the chassis structure 1 can be reduced, while the neatness of the appearance of the chassis structure 1 is improved. At the same time, part of the second pipe 1313 is also hidden in the accommodating cavity 100, further improving the neatness of the appearance of the chassis structure 1 and the safety of use of the second pipe 1313.

In this embodiment, the water storage device 130 of the water supply and drainage module 13 includes the first water storage member 130a and the second water storage member 130b, and the components of the connection structure 131 such as the third pipe 1311, the first pipe 1312, and the second pipe 1313 can be set to two, so as to respectively realize the communication between the water inlet 120 of the household water unit 12 and the first water storage member 130a and the communication between the drain outlet 121 and the second water storage member 130b.

[0085] In this way, by setting the first water storage component 130a and the second water storage component 130b, the first water storage component 130a can supply water to the water inlet 120 of the household water unit 12, and the second water storage component 130b can receive water discharged from the drain outlet 121 of the household unit. The first water storage component 130a and the second water storage component 130b are respectively set to store the clean water required by the household water unit 12 and the sewage discharged from the household water unit 12, so as to avoid the mixing of clean water and sewage and affect the user experience.

[0086] Optionally, the first water storage member 130a and the second water storage member 130b may be water storage tanks, water storage boxes, etc., which may be selected according to actual conditions and are not specifically limited in this embodiment.

In some examples, the chassis structure 1 also includes a sewage treatment device 14, which is arranged on the base 10 and connected to the second water storage part 130b. The sewage treatment device 14 is used to purify the sewage in the second water storage part 130b. In this way, by setting up the sewage treatment device 14, the sewage treatment device 14 can purify the sewage in the second water storage part 130b of the water supply and drainage module 13, so that the purified water in the second water storage part 130b can be directly discharged, ensuring that the prefabricated building can meet the drainage requirements of the household water unit 12 in any environment (such as suburbs, forests, etc., which are not convenient for connecting with the urban water supply and drainage system), thereby improving the flexibility of the construction environment of the prefabricated building.

[0089] In some other examples, the chassis structure 1 further includes a rainwater collection and purification device 15, which is disposed on the base 10 and connected to the first water storage member 130a. The rainwater collection and purification device 15 is used to collect rainwater and provide purified rainwater to the first water storage member 130a. In this way, by providing the rainwater collection and purification device 15, the rainwater collection and purification device 15 can collect rainwater and provide purified rainwater to the first water storage member 130a of the water supply and drainage module 13, thereby replenishing the water in the first water storage member 130a, ensuring that the prefabricated building is in any environment (such as suburbs, forests, etc., which are not convenient for connecting with the urban drainage system) The water supply demand of the household water unit 12 can be guaranteed, thereby improving the flexibility of the construction environment of the prefabricated building.
