[0020] According to the above structure, when in use, the lifting platform 3 is driven to rise and fall by the lifting component 4, so as to adjust the overall height of the lower cabinet 1, so as to adapt to the height of the elderly and improve the practicality of the device. The U-shaped connecting plate 7 and the second storage rack 8 are driven to rise and fall by the lifting bracket 6, so as to facilitate the taking of items on the second storage rack 8 when in use, thereby further improving the practicality of the device.

[0023] like Figure 3 and 4 As shown, the lifting platform 3 includes a magnetic plate 31 and a stone panel 32. The bottom end of the stone panel 32 is provided with a groove matching the magnetic plate 31. The inside of the groove is fixedly connected with a stainless steel shell 33. The stainless steel shell 33 is magnetically connected to the magnetic plate 31. A wedge-shaped baffle 34 is fixedly connected to one side of the top of the magnetic plate 31. The bottom end of the stone panel 32 is fixedly connected with a cylindrical baffle 35. The cylindrical baffle 35 is slidably connected to the top of the lower cabinet 1.

[0024] According to the above structure, the magnetic plate 31 is magnetically engaged with the stainless steel shell 33, which facilitates the disassembly and assembly of the stone panel 32, and the wedge-shaped retaining bar 34 plays a role in retaining water, preventing water from seeping along the gap between the stone panel 32 and the wall.

[0025] like Figure 3-5 As shown, the lifting assembly 4 includes four lifting components 41 distributed in a rectangular array, a transmission component 42 is arranged between two adjacent lifting components 41, and the two adjacent lifting components 41 are connected in transmission through the transmission component 42, a support plate 44 is arranged on the top of the lower cabinet 1, a driving component 43 is fixedly installed on the top of the support plate 44, and the driving component 43 is connected in transmission with one of the transmission components 42, and the lifting component 41 includes a square tube 411 fixedly connected to the corner of the lower cabinet 1, a top cover 412 is fixedly connected to the top of the square tube 411, a lifting column 413 is movably connected inside the square tube 411, and the top of the lifting column 413 passes through the top cover 412, and the side wall of the lifting column 413 is provided with two rows of tooth groups, each row of tooth groups includes a square along the height of the lifting column 413.

[0026] According to the above structure, when driving the lifting platform 3 to rise and fall, by starting the first servo motor 432, through the rotation of the two bevel gears 433, the corresponding connecting rod 421 is driven to rotate, and the first gears 422 at both ends of the connecting rod 421 rotate with the connecting rod 421, driving the lifting column 413 connected thereto to rise and fall. After the lifting column 413 is lifted and lowered, it drives the first gear 422 meshing therewith to rotate, and then drives the connecting rod 421 connected to the corresponding first gear 422 to rotate. After the connecting rod 421 rotates, it drives the first gear 422 at the other end to rotate, and then drives the other lifting columns 413 to rise and fall synchronously, so that the four lifting columns 413 can be driven to rise and fall synchronously by the first servo motor 432. After the shell cover 431 is lifted and lowered synchronously, the magnetic plate 31 can be driven to rise and fall, and then the stone panel 32 can be driven to rise and fall. The lifting component 4 occupies part of the space on the top of the lower cabinet 1 and the space at the corners. Compared with the folding lift, it occupies less space and is more practical.

[0027] like Figure 5 As shown, a limiting component 45 for positioning the lifting column 413 is arranged inside the square cylinder 411, and the limiting component 45 includes a rotating shaft 451 rotatably connected to the inside of the square cylinder 411, and a second gear 452 is fixedly sleeved on the side wall of the rotating shaft 451, and the second gear 452 is meshed with one row of teeth 414 on the lifting column 413, and a cylinder 453 is fixedly connected to one side of the second gear 452, and a ratchet 454 is fixedly connected to one end of the cylinder 453, and a second servo motor 455 is fixedly connected to one end of the inner wall of the square cylinder 411, and the output shaft of the second servo motor 455 is fixedly connected to There is a connecting shaft 456, one end of which is fixedly connected to an end head 457, a side wall of the end head 457 is provided with an arc groove 458, a sleeve 46 is movably sleeved on the side wall of the end head 457, an inner wall of the sleeve 46 is fixedly connected to a limit block 461, the limit block 461 is rotatably connected to the inside of the arc groove 458, a side wall of the connecting shaft 456 is provided with a torsion spring 459, one end of the torsion spring 459 is fixedly connected to the side wall of the connecting shaft 456, the other end of the torsion spring 459 is fixedly connected to the inner wall of the sleeve 46, and the outer wall of the sleeve 46 is fixedly connected to a latch tooth 462 that cooperates with the ratchet 454.

[0028] According to the above structure, the limiting component 45 plays a role in supporting the lifting column 413. When the lifting platform 3 completes the lifting, the limiting component 45 supports the driving component 43 to reduce the pressure of the gravity of the lifting platform 3 on the first gear 422 and the rotating shaft of the first servo motor 432. When the lifting column 413 moves upward, the lifting column 413 drives the second gear 452 to rotate counterclockwise through the teeth 414. At this time, the ratchet 454 rotates counterclockwise synchronously with the cylinder 453. The ratchet 454 rotates counterclockwise, and the ratchet on its side wall drives the latch tooth 462 to rotate clockwise. The sleeve 46 rotates counterclockwise with the latch tooth 462. The limiting block 461 can rotate clockwise inside the arc groove 458 and twist the torsion spring 459. When a ratchet rotates, the sleeve 46 and the limiting block are rotated under the torsion of the torsion spring 459. 461 and the latch tooth 462 both rotate counterclockwise to engage with a ratchet. When the lifting column 413 continues to rise, the above-mentioned actions are repeated. When the lifting column 413 stops rising, the latch tooth 462 engages with the corresponding ratchet, thereby preventing the ratchet 454 from reversing, thereby locking the rotating shaft 451 and the second gear 452. The second gear 452 supports the lifting column 413 by cooperating with the tooth 414, thereby improving the stability of the lifting column 413. When the lifting column 413 needs to descend, the second servo motor 455 drives the connecting shaft 456 and the end 457 to rotate clockwise, and the end of the end 457 drives the limit block 461 to rotate clockwise, thereby driving the sleeve 46 and the latch tooth 462 to rotate clockwise, unlocking the ratchet 454, so that the lifting column 413 can descend freely.

[0029] like Figure 6 and 7 As shown, the lifting bracket 6 includes a V-shaped frame 61 fixedly connected to one side of the mounting column 5, the top of the V-shaped frame 61 is rotatably connected to the first support rod 62, one end of the V-shaped frame 61 is rotatably connected to the second support rod 63, one end of the first support rod 62 is rotatably connected to the transmission rod 64, one end of the transmission rod 64 is rotatably connected to the side wall of the second support rod 63, the middle part of the first support rod 62 is rotatably connected to the first rotating block 65, one end of the inner wall of the second support rod 63 is rotatably connected to the second rotating block 66, the middle part of the first rotating block 65 is rotatably connected to the screw 68, the side wall of the screw 68 is threadedly connected to the second rotating block 66, one end of the first rotating block 65 is fixedly connected to the third private service motor 67, and the output shaft of the third private service motor 67 is fixedly connected to one end of the screw 68.

[0030] According to the above structure, when in use, the third private service motor 67 is started to drive the screw 68 to rotate, and the screw 68 is threadedly connected to the second rotating block 66. After the screw 68 rotates, it drives the second rotating block 66 to move along the side wall of the screw 68, thereby changing the distance between the first rotating block 65 and the second rotating block 66. After the distance between the two is changed, the transmission of the transmission rod 64 can realize the change of the angle of the first rotating block 65 and the second support rod 63, thereby realizing the lifting and lowering of the U-shaped connecting plate 7 at the end of the second support rod 63.

[0031] The working principle of the present invention is as follows: when driving the lifting platform 3 to rise and fall, the first servo motor 432 is started to rotate through the two bevel gears 433 to drive the corresponding connecting rod 421 to rotate, and the first gears 422 at both ends of the connecting rod 421 rotate with the connecting rod 421, driving the lifting column 413 connected thereto to rise and fall, and after the lifting column 413 is lifted and lowered, it drives the first gear 422 meshing therewith to rotate, and then drives the connecting rod 421 connected to the corresponding first gear 422 to rotate, and after the connecting rod 421 rotates, it drives the first gear 422 at the other end to rotate, and then drives the other lifting columns 413 to rise and fall synchronously, so that the four lifting columns 413 can be driven to rise and fall synchronously by the first servo motor 432, and the shell cover 431 can drive the magnetic plate 31 to rise and fall synchronously after it rises and falls synchronously. The lifting assembly 4 occupies part of the space on the top of the lower cabinet 1 and the space at the corners. Compared with the folding lift, the space occupied by the lifting assembly 4 is small and more practical. The limiting component 45 supports the lifting column 413. When the lifting platform 3 completes the lifting, the limiting component 45 supports the driving component 43 to reduce the pressure of the gravity of the lifting platform 3 on the first gear 422 and the rotating shaft of the first servo motor 432. When the lifting column 413 moves upward, the lifting column 413 drives the second gear 452 to rotate counterclockwise through the teeth 414. At this time, the ratchet 454 rotates counterclockwise synchronously with the cylinder 453. The ratchet 454 rotates counterclockwise, and the ratchet on its side wall drives the card teeth 462 to rotate clockwise, and the sleeve 46 As the latch tooth 462 rotates counterclockwise, the limit block 461 can rotate clockwise inside the arc groove 458 and twist the torsion spring 459. After one ratchet rotates, the sleeve 46, the limit block 461, and the latch tooth 462 all rotate counterclockwise to cooperate with the next ratchet under the torsion of the torsion spring 459. When the lifting column 413 continues to rise, the above-mentioned actions are repeated. When the lifting column 413 stops rising, the latch tooth 462 clamps the corresponding ratchet to prevent the ratchet wheel 454 from reversing, thereby locking the rotating shaft 451 and the second gear 452. The second gear 452 supports the lifting column 413 by cooperating with the tooth 414 to improve the stability of the lifting column 413. When the lifting column 413 needs to descend, the second servo motor 455 drives the connecting The shaft 456 and the end head 457 rotate clockwise, and the end of the end head 457 drives the limit block 461 to rotate clockwise, thereby driving the sleeve 46 and the latch tooth 462 to rotate clockwise, unlocking the ratchet 454, so that the lifting column 413 can descend freely. When in use, the third private service motor 67 is started to drive the screw 68 to rotate, and the screw 68 is threadedly connected to the second rotating block 66. After the screw 68 rotates, it drives the second rotating block 66 to move along the side wall of the screw 68, thereby changing the distance between the first rotating block 65 and the second rotating block 66. After the distance between the two is changed, the transmission rod 64 is transmitted to realize the change of the angle of the first rotating block 65 and the second support rod 63, thereby realizing the lifting and lowering of the U-shaped connecting plate 7 at the end of the second support rod 63.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
