[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, 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 embodiments described are 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 making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1-9As shown, the miniaturized electric lifting device for the dining table top provided in this embodiment includes a primary portion, a lifting assembly, a secondary portion, and a power supply assembly; the secondary portion is slidably connected to the primary portion via the lifting assembly; and the lifting assembly and the power supply assembly are electrically connected. It will be understood by those skilled in the art that the miniaturized electric lifting device for the dining table top provided in this application, wherein the primary portion, the secondary portion, the lifting assembly, and the power supply assembly are all modular structures, has a simple structure and has the advantages of miniaturization and modularization. In addition, it is easy to install, convenient to use, and has a low production cost.

[0027] Furthermore, the secondary portion includes a first top plate 201; the primary portion includes a first bottom plate 103; and the lifting assembly includes an electric push rod 402. The push rod top rod 401 of the electric push rod 402 is fixed to one side of the first top plate 201; and the fixed end of the electric push rod 402 is fixed to one side of the first bottom plate 103. Those skilled in the art will appreciate that the first top plate 201 is raised and lowered by the raising and lowering of the electric push rod 402.

[0028] Furthermore, the first-level portion further includes a second top plate 104; a first through-hole 106 is defined at the center of the second top plate 104; the lifting assembly further includes multiple sets of optical axes 105; the second top plate 104 is disposed below the first top plate 201; the electric push rod top rod 401 of the electric push rod 402 passes through the first through-hole 106; and multiple sets of optical axes 105 are vertically fixed between the second top plate 104 and the first bottom plate 103. Those skilled in the art will appreciate that the second top plate 104 is used to support the first top plate 201. When the electric push rod 402 falls back, the first top plate 201 descends and abuts against the top of the second top plate 104, thereby preventing the first top plate 201 from shaking and improving the stability of the first top plate 201 from tilting.

[0029] Furthermore, the secondary portion also includes a second base plate 203 and a first housing 202; the lifting assembly also includes multiple groups of linear bearings 204 that match the optical axis 105; the second base plate 203 is provided with a second through hole 205 and multiple groups of third through holes; the multiple groups of third through holes are evenly arranged next to the second through hole 205; the linear bearings 204 are fixed to the second base plate 203 after being inserted into the third through holes; the linear bearings 204 slide on the optical axis 105; the first housing 202 is fixed to the first top plate 201 and the second base plate 203 at both ends respectively; the electric push rod 402 is passed through the second through hole 205. It will be understood by those skilled in the art that the second base plate 203 slides on the optical axis 105 via the linear bearings 204, which can improve the stability of the lifting of the primary portion. At the same time, the optical axis 105 is firmly fixed by the second top plate 104 limiting the position of the optical axis 105, preventing the linear bearings 204 from shaking when sliding.

[0030] Furthermore, the number of the optical axes is 5, and the number of the linear bearings 204 is 3. Those skilled in the art will appreciate that 3 sets of linear bearings 204 can ensure sliding stability while reducing costs.

[0031] Furthermore, the power supply assembly also includes an electrical box 301, a power module 305, a base plate 101 and a drag chain 303; the first-level part also includes a second shell 102; one end of the second shell 102 is fixed to the first bottom plate 103, and the other end is fixed to the base plate 101; the first shell 202 passes through the base plate 101; the first shell 202 is located inside the second shell 102; the electrical box 301 is arranged outside or inside the second shell 102; the electrical box 301 is fixed to the base plate 101; the power module 305 is fixed inside the electrical box 301; one end of the drag chain 303 is fixed to the first top plate 201, and the other end is fixed to the electrical box 301; the electric push rod 402 is electrically connected to the power module 305. Those skilled in the art will understand that the drag chain 303, also known as the cable protection drag chain 303 Cable carrier, is a device that restrains cables or wires or air pressure pipes and oil pressure pipes to facilitate their rotation and movement. By routing the wires in the drag chain 303 , power can be provided to external devices on the first top plate. In addition, a spring power cord is used instead of the drag chain, thereby further reducing costs.

[0032] Furthermore, the power supply assembly further includes a control module 304 equipped with a chip; the control module 304 is fixed in the electrical box 301; the control module 304 is electrically connected to the power module 305. Those skilled in the art will appreciate that the control module 304 is prior art and will not be described in detail here.

[0033] Furthermore, the drag chain 303 is arranged in the electrical box 301 .

[0034] Furthermore, the power supply assembly further includes a drag chain box 302 ; the drag chain 303 is disposed in the drag chain box 302 ; and the drag chain box 302 and the electrical appliance box 301 are fixed to each other.

[0035] Furthermore, the first housing 202 and the second housing 102 are annular or square.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
