[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Figures 1 to 3 As shown, an embodiment of the present invention provides a deformable multifunctional coffee table, the coffee table comprising: A plurality of horizontal platforms 100 stacked in a vertical direction, wherein adjacent horizontal platforms 100 are connected by at least three groups of telescopic support columns 200, wherein the telescopic support columns 200 can change the distance between adjacent horizontal platforms 100 during the telescopic process, and a support foot 150 is provided on the bottommost horizontal platform 100, wherein the telescopic support columns 200 and the horizontal platform 100 are detachably connected; When the telescopic support column 200 is extended, the distance between adjacent horizontal surfaces 100 is sufficient for users to place items to serve as a storage rack. When the telescopic support column 200 is shortened, the distance between the upper end surface of the uppermost horizontal surface 100 and the bottom of the support foot 150 is less than fifty centimeters.

[0030] In the present embodiment, the coffee table is composed of a plurality of the horizontal surfaces 100 and the telescopic support columns 200. Since the telescopic support columns 200 are telescopic, when the coffee table is not needed and needs to be put aside, the telescopic support columns 200 are extended. At this time, the distance between adjacent horizontal surfaces 100 increases, and the coffee table is transformed into a shelf form, on which items can be placed, or it can be transformed into a table, so that the coffee table will not be idle and occupy family space in vain, and at the same time increase the family's storage space. When it is needed to function as a coffee table, the telescopic support columns 200 are shortened, so that a plurality of horizontal surfaces 100 are stacked, and the total height of the plurality of horizontal surfaces 100 and the telescopic support columns 200 is less than fifty centimeters, so that it can be used as a coffee table.

[0031] The deformable multifunctional coffee table disclosed in the embodiment of the present invention is arranged by stacking a plurality of horizontal surfaces 100, and connecting adjacent horizontal surfaces 100 through retractable telescopic support columns 200, so that the distance between adjacent horizontal surfaces 100 can be changed. When the telescopic support columns 200 are extended, the distance between adjacent horizontal surfaces 100 increases, and the structure composed of the horizontal surface 100 and the telescopic support columns 200 can be used as a shelf. When the telescopic support columns 200 located at the uppermost layer are extended, the horizontal surface 100 located at the top is raised, and the coffee table can be used as a table. When the telescopic support columns 200 are shortened, the horizontal surfaces 100 are stacked on each other, and the structure composed of the horizontal surface 100 and the telescopic support columns 200 can be used as a coffee table. Compared with the traditional coffee table structure, the present invention can be used as a coffee table, and can also be used as a shelf when the coffee table is not needed, for storing household items, thereby improving the functionality of the coffee table and reducing the waste of household space.

[0033] As a preferred implementation in this embodiment, Figures 9 to 12 As shown, the telescopic support column 200 includes: A spiral airbag 210 and a spiral sheet 220, wherein the spiral airbag 210 and the spiral sheet 220 are coaxially arranged and intertwined with each other, and the spiral airbag 210 and the spiral sheet 220 are fixedly connected; An inflation component 240, used to inflate the spiral airbags 210, each spiral airbag 210 is individually controlled by an inflation valve; In this embodiment, when the spiral airbag 210 is inflated, the inflation valve corresponding to the spiral airbag 210 is opened, and the inflation component 240 extracts external air and fills it into the spiral airbag 210 during operation, so that the spiral airbag 210 expands, and the spiral airbag 210 stretches when expanding. Since the spiral airbag 210 and the spiral sheet 220 are fixedly connected, the spiral sheet 220 can serve as the skeleton of the spiral airbag 210, so that the spiral airbag 210 mainly changes in the axial direction when expanding, and the radial change of the spiral airbag 210 is small, so that the spiral airbag 210 can lift the horizontal platform surface 100 when used as a support. The spiral airbag 210 is a rubber airbag, the spiral sheet 220 is a metal elastic sheet, and the inflation component 240 is a plunger-type inflation pump.

The spiral air tube 142 is wound around the outside of the telescopic support column 200 and can also be used as decoration. When the horizontal platform surface 100 is lifted, the spiral air tube 142 is stretched.

[0034] As a preferred implementation in this embodiment, the spiral airbag 210 is further sleeved with a telescopic tube 230, an elastic skeleton is arranged inside the telescopic tube 230, and a cylindrical flexible layer is arranged outside the elastic skeleton. The flexible layer does not undergo elastic deformation or undergoes very small elastic deformation under the action of external force, such as nylon material. The telescopic tube 230 serves to limit the radial position of the spiral airbag 210, and is used to reduce the radial deformation of the spiral airbag 210.

[0035] As a preferred implementation in this embodiment, the lower shell 110 and the upper cover 120 are both provided with mounting grooves, the mounting grooves are recessed into the horizontal platform 100, and the ends of the telescopic support column 200 are respectively fixed to the mounting grooves on the lower shell 110 and the upper cover 120, and when the telescopic support column 200 is shortened, the telescopic support column 200 can be retracted into the horizontal platform 100; It should be noted that no mounting groove is provided on the upper side of the horizontal platform surface 100 located at the uppermost layer, so that the upper side of the horizontal platform surface 100 located at the uppermost layer is straight.

[0036] In this embodiment, four groups of telescopic supports 200 are provided, and the telescopic supports 200 are distributed at the four corners of the horizontal platform 100 .

[0037] As a preferred implementation of this embodiment, the horizontal surface 100 is a hollow structure, and a heating component 300 is further provided inside the horizontal surface 100 for heating the horizontal surface 100, so that the coffee table can release heat to play a role in heating. At the same time, when used as a shelf, food can also be placed to play a role in heat preservation, or used as a drying rack, thereby expanding the function of the coffee table; In this embodiment, if Figure 6 As shown, the heating component 300 is an electric heating rod structure, and the heating components 300 are evenly distributed in the horizontal platform 100. Each heating component 300 in the horizontal platform 100 is controlled by a separate temperature controller, and the temperature controller is electrically connected to the controller through a wire.

[0038] As a preferred implementation in this embodiment, the upper cover 120 is provided with a plurality of evenly distributed grid holes, and a movable grid 121 is provided at the grid hole. A grid control unit 130 is provided in the horizontal platform 100 to control the end surface of the movable grid 121 to be flush with the end surface of the upper cover 120. At the same time, the grid control unit 130 controls the lifting and lowering of the movable grid 121 to control the opening of the grid hole; like Figure 7 and Figure 8 As shown, both ends of the movable grid 121 are provided with limit ears 122, and the limit ears 122 are provided with waist-shaped holes.

The compression spring 134 is sleeved on the limiting column 132, and the limiting column 132 is fixedly connected to the limiting block 131. The two ends of the compression spring 134 are respectively abutted against the limiting bolt 133 and the limiting lug 122. A gasket is provided between the compression spring 134 and the limiting lug 122. Two waist-shaped holes are provided. Two limiting columns 132, limiting bolts 133, and compression springs 134 are provided, so that the movable grid 121 can only move along a straight line. The plurality of movable grids 121 are connected to each other through a crossbeam structure, and the grid control unit 130 further includes an adjusting threaded tube 135 fixedly connected to the center position and an adjusting bolt 136 rotatably connected to the lower housing 110. When the adjusting bolt 136 rotates, it can drive the adjusting threaded tube 135 to rise and fall, thereby driving the movable grid 121 to rise and fall, and then opening / closing the grid hole; The adjusting bolt 136 is rotatably connected to the lower housing 110 via an elastic retaining spring; Preferably, the normally closed control valve 141 is a three-way reversing valve, and the three interfaces of the 141 are respectively connected to the spiral airbag 210, the spiral air pipe and the interior of the lower shell 110. The normally closed control valve 141 is used to switch the connection relationship among the three. In the normally closed state, the spiral airbag 210, the spiral air pipe 142 and the interior of the lower shell 110 are not connected. When inflating, the spiral airbag 210 is connected to the spiral air pipe 142. When deflated, the spiral airbag 210 is connected to the interior of the lower shell 110, and the interior of the lower shell 110 is connected to the spiral air pipe 142. When heating, the inflatable component 240 inflates the lower shell 110 through the normally closed control valve 141, and at the same time, the movable grid 121 is opened; In this embodiment, the normally closed control valve 141 is a four-position three-way reversing valve in the prior art. The normally closed control valve 141 includes a cylindrical valve shell, a valve core rotatably connected to the inside of the valve shell, and a motor driving the valve core to rotate. The valve shell is provided with three connecting holes on the same circumference, and the valve core is provided with a V-shaped connecting channel. When the connecting channel rotates, different connecting holes can be connected, thereby realizing the connecting relationship between different connecting holes.

[0039] It should be noted that, since the telescopic support 200 and the horizontal platform 100 are detachably connected, the horizontal platform 100 can be placed on the wall after being disassembled and used as a heater. At this time, the heating component 300 heats the outside air and the movable grid 121 is opened.

[0040] As a preferred implementation in this embodiment, a pressure relief valve is also provided at the output end of the inflation component 240 to prevent structural damage caused by excessive pipeline pressure.

[0041] As a preferred implementation in this embodiment, a pressure sensor is also provided in the spiral airbag 210 for detecting the pressure in the spiral airbag 210. The pressure sensor is electrically connected to the controller via a wire. The pressure sensor in the spiral airbag 210 is connected to an external connector via a wire. The external connector can be plugged into a circuit board in the horizontal platform 100. The circuit board in the horizontal platform 100 is electrically connected to the control unit via an electrical connector and a wire. The pressure sensor is used to detect the air pressure in the spiral airbag 210 and the quality of the items on the coffee table, so as to prevent the coffee table from being damaged. In the present embodiment, when the spiral airbag 210 is inflated, the sensor in the spiral airbag 210 can detect the air pressure. When items are placed on the horizontal platform 100, the load-bearing capacity of the telescopic support column 200 increases, and the air pressure in the spiral airbag 210 increases. However, there is an upper limit of air pressure in the spiral airbag 210. When monitoring the air pressure in the spiral airbag 210, the detected real-time air pressure value is compared with the preset air pressure value. When it is less than the preset air pressure value, the air pressure in the spiral airbag 210 is at a safe air pressure. When it is greater than the preset air pressure value, the control unit sounds an alarm through the sound and light alarm device arranged in the horizontal platform 100. The preset air pressure value is less than the upper limit of air pressure of the spiral airbag 210, that is, the critical air pressure of the spiral airbag 210 when it explodes.

[0042] Preferably, a distance detection module, such as an ultrasonic ranging module, is also provided on the horizontal platform surface 100. The distance detection module is electrically connected to the controller via a wire and is used to detect the distance between adjacent horizontal platform surfaces 100. The controller also controls the telescopic tube 230 to inflate the spiral airbag 210 based on the detection result of the distance detection module, so that the distance between adjacent horizontal platform surfaces 100 remains unchanged, that is, when the distance between adjacent horizontal platform surfaces 100 decreases, the inflation component 240 inflates the spiral airbag 210.
