[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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.

[0026] like Figure 1-Figure 9As shown, the miniaturized electric lifting device for the dining table top provided in this embodiment includes a primary part, a lifting assembly, a secondary part and a power supply assembly; the secondary part is slidably connected to the primary part through the lifting assembly; the lifting assembly and the power supply assembly are electrically connected. Those skilled in the art can understand that the miniaturized electric lifting device for the dining table top provided in this application, its primary part, secondary part, lifting assembly and power supply assembly are all modular structures, so its structure is simple and has the advantages of miniaturization and modularization. In addition, it is easy to install, easy to use and has low production cost.

[0027] Further, the secondary part includes a first top plate 201; the primary part includes a first bottom plate 103; the lifting assembly includes an electric push rod 402; the electric push rod top rod 401 of the electric push rod 402 is fixed to one side of the first top plate 201; 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 can understand that the first top plate 201 is raised and lowered by the lifting and lowering of the electric push rod 402.

[0028] Furthermore, the first-level part further includes a second top plate 104; a first through hole 106 is provided at the center of the second top plate 104; the lifting assembly further includes a plurality of optical axes 105; the second top plate 104 is arranged below the first top plate 201; the electric push rod top rod 401 of the electric push rod 402 is provided with the first through hole 106; and a plurality of optical axes 105 are vertically fixed between the second top plate 104 and the first bottom plate 103. It can be understood by those skilled in the art 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 falls downward 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 so that it will not deviate sideways.

[0029] Furthermore, the secondary part also includes a second bottom plate 203 and a first housing 202; the lifting assembly also includes a plurality of linear bearings 204 matching the optical axis 105; the second bottom plate 203 is provided with a second through hole 205 and a plurality of third through holes; the plurality of third through holes are evenly arranged beside the second through hole 205; the linear bearing 204 is inserted into the third through hole and fixed to the second bottom plate 203; the linear bearing 204 slides on the optical axis 105; the first housing 202 is respectively fixed to the first top plate 201 and the second bottom plate 203 at both ends; the electric push rod 402 is penetrated by the second through hole 205. Those skilled in the art can understand that the second bottom plate 203 slides on the optical axis 105 through the linear bearing 204, which can improve the stability of the lifting of the primary part, and at the same time, the optical axis 105 is firmly fixed by the second top plate 104 limiting the optical axis 105, so as to prevent the linear bearing 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 can understand that 3 sets of linear bearings 204 can ensure the stability of sliding and reduce the cost.

[0031] Further, the power supply assembly also includes an electrical box 301, a power module 305, a substrate 101 and a drag chain 303; the first level also includes a second housing 102; one end of the second housing 102 is fixed to the first bottom plate 103, and the other end is fixed to the substrate 101; the first housing 202 passes through the substrate 101; the first housing 202 is located in the second housing 102; the electrical box 301 is arranged outside or inside the second housing 102; the electrical box 301 is fixed to the substrate 101; the power module 305 is fixed in 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 can understand that the drag chain 303, also known as the cable protection drag chain 303Cable carrier, is a device for binding 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 provided 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 can understand that the control module 304 is a 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 arranged in the drag chain box 302 ; the drag chain box 302 and the electrical 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.
