[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Reference Figure 1 An automatic screen adjustment device for a garbage collection station includes a main body 1, a lifting mechanism 2, an angle adjustment mechanism 3, and a fixing mechanism 4. A main board 11 is fixed to the side of the main body 1, and a touch screen 111 is fixed on the main board 11. A camera window 12 is opened above the main board 11 on the side of the main body 1, and a barcode scanning window 13 and a card swiping window 14 are opened on one side of the main board 1. A camera 15, a barcode scanner 16, and a card swiping device 17 are fixed along one side of the main body 1 along its width direction, and the three are spaced apart along the height direction of the main body 1. All parts except the angle adjustment mechanism 3 and the fixing mechanism 4 are electrically connected and controlled by the main board 11. The lifting mechanism 2 is located on one side of the main body 1 and is used to adjust the height of the main body 1. The angle adjustment mechanism 3 is located below the main body 1 and is used to adjust the angle of the main body 1 to reduce glare and inconvenience to the user. A first switch 18 and a second switch 19 are also fixed on the side of the main body 1, both of which are used to control the angle adjustment mechanism 3.

[0026] When in use, the user can select their height on the touch screen 111. After receiving the instruction, the motherboard 11 will send a signal to the lifting mechanism 2, which will enable the lifting mechanism 2 to adjust the body 1 to a suitable height. The touch screen 111 will stay at a comfortable operating position at that height. When the touch screen 111 is reflective, the user can also touch the first switch 18 and the second switch 19 to activate the angle adjustment mechanism 3, so that the body 1 is adjusted to a non-reflective position for easy operation.

[0027] Reference Figure 1-2 The lifting mechanism 2 includes a lifting assembly 21 and a power assembly 22. There are two sets of lifting assemblies 21, each set positioned on one side of the angle adjustment mechanism 3. Each lifting assembly 21 includes a vertical plate 211, a screw 212, and a slider 213. The vertical plate 211 is positioned on the side of the main body 1 furthest from the touchscreen 111 and is internally hollow. The screw 212 is positioned along the height of the vertical plate 211 and is located within the vertical plate 211. The top end of the screw 212 passes through the top of the vertical plate 211 and is rotatably connected to it, while the bottom end is rotatably connected to the bottom of the vertical plate 211. The slider 213 is threaded onto the screw 212 and is fixed to the angle adjustment mechanism 3. A groove 2111 is provided on the side of the vertical plate 211 near the main body 1. The groove 2111 is positioned along the height of the vertical plate 211, and the slider 213 moves within the groove 2111, slidably connected to the vertical plate 211. The power unit 22 drives the two screws 212 to rotate.

[0028] When the power assembly 22 is started, it can drive the two screws 212 to rotate. Since the two sliders 213 are fixed to the angle adjustment mechanism 3, and with the limiting effect of the slide groove 2111, the sliders 213 can only move along the height direction of the screws 212, thereby driving the angle adjustment mechanism 3 to move up and down. The body 1 is set above the angle adjustment mechanism 3, so the body 1 can be raised and lowered.

[0029] Reference Figure 2 The power assembly 22 is positioned above the two vertical plates 211 and includes a first motor 221, a first pulley 222, and a second pulley 223. The first motor 221 is fixed to the outer top surface of one of the vertical plates 211, and its output shaft is fixedly connected to one end of a nearby screw 212 extending out of the vertical plate 211. The first pulley 222 is fixed to the output shaft of the first motor 221, and the second pulley 223 is fixed to one end of the other screw 212 extending out of the vertical plate 211. A belt 224 is wound around both the first pulley 222 and the second pulley 223. A protective cover 225 is also fixed between the two vertical plates 211. The protective cover 225 is hollow inside and open at the bottom. The power assembly 22 is located inside the protective cover 225, serving a protective and dustproof function. The first motor 221 is electrically connected to the main board 11.

[0030] When the first motor 221 is started, the output shaft of the first motor 221 can drive the screw 212 fixed to it to rotate, and can also drive the first pulley 222 to rotate, which in turn drives the belt 224 to rotate, thereby driving the second pulley 223 to rotate, which in turn drives the screw 212 fixed to the second pulley 223 to rotate, ultimately realizing the rotation of the two screws 212 and providing power to the lifting assembly 21.

[0031] Reference Figure 1-4 The angle adjustment mechanism 3 includes a mounting box 31, a first mounting plate 32, a second mounting plate 33, a first drive assembly 34, a second drive assembly 35, and a third drive assembly 36. The mounting box 31 is located below the main body 1. Two sliders 213 are fixedly connected to the side of the mounting box 31. The lifting mechanism 2 adjusts the height of the main body 1 by adjusting the height of the mounting box 31, and the mounting box 31 is hollow inside. The first mounting plate 32 and the second mounting plate 33 are both arranged along the height direction of the mounting box 31. The first mounting plate 32 and the second mounting plate 33 are both disposed inside the mounting box 31 and are spaced apart along the length direction of the mounting box 31 and fixedly connected to the mounting box 31.

[0032] Reference Figure 1 and Figure 3 The first drive assembly 34 includes a fixing block 341, a first cylinder 342, a first rack 343, a first sleeve 344, and a first spur gear 345. The fixing block 341 is fixedly disposed within the mounting box 31 at one end along its length and is located on the side of the first mounting plate 32 away from the second mounting plate 33. The first switch 18 is electrically connected to the first cylinder 342, and the piston rod of the first cylinder 342 is positioned facing the first mounting plate 32. The first rack 343 is disposed between the first mounting plate 32 and the second mounting plate 33 and is positioned along the length of the mounting box 31. One end of the first rack 343 passes through the first mounting plate 32 and is slidably connected to it, and the other end also passes through the second mounting plate 33 and is slidably connected to it. The end of the first rack 343 passing through the first mounting plate 32 is fixedly connected to the piston rod of the first cylinder 342. The first sleeve 344 is positioned along its height and between the first mounting plate 32 and the second mounting plate 33. The top end of the first sleeve 344 passes through the top of the mounting box 31 and is rotatably connected to it via a bearing, which prevents the first sleeve 344 from slipping out of the mounting box 31. A first spur gear 345 is sleeved on the bottom end of the first sleeve 344 and fixedly connected to it, and the first spur gear 345 meshes with the first rack 343. The third drive assembly 36 is positioned on top of the first sleeve 344.

[0033] Clicking the first switch 18 activates the first cylinder 342, which in turn drives the first rack 343 to move. Since the first sprocket 345 meshes with the first rack 343, the first sprocket 345 rotates, causing the first sleeve 344 to rotate. This, in turn, causes the third drive assembly 36 to rotate horizontally to a position that is convenient for the user.

[0034] Reference Figure 1 and Figure 3 The second drive assembly 35 includes a second cylinder 351, a second rack 352, a second sleeve 353, and a second spur gear 354. A second switch 19 is electrically connected to the second cylinder 351. The second cylinder 351 is fixedly disposed within the mounting housing 31 on the side of the second mounting plate 33 away from the first mounting plate 32, with its piston rod facing the first mounting plate 32. The second rack 352 is disposed between the first mounting plate 32 and the second mounting plate 33, parallel to the first rack 343, and on the side of the first sleeve 344 away from the first rack 343. One end of the second rack 352 passes through and is slidably connected to the second mounting plate 33, and the other end also passes through and is slidably connected to the first mounting plate 32. The end of the second rack 352 passing through the second mounting plate 33 is fixedly connected to the piston rod of the second cylinder 351. The second sleeve 353 is disposed along its height and fitted inside the first sleeve 344. The length of the second sleeve 353 is longer than that of the first sleeve 344, and both ends protrude from the first sleeve 344 and are rotatably connected to the first sleeve 344 via bearings. The bearings ensure that the second sleeve 353 will not slip out of the first sleeve 344. The second spur gear 354 is fitted onto the bottom end of the second sleeve 353 and fixedly connected to it, and the second spur gear 354 meshes with the second rack 352. The top end of the second sleeve 353 is also connected to the third drive assembly 36.

[0035] Reference Figure 1 and Figure 4The third drive assembly 36 includes a mounting base 361, a first bevel gear 362, a second bevel gear 363, a first rotating rod 364, and a second rotating rod 365. The mounting base 361 is U-shaped, and its bottom is fixedly connected to the top of the first sleeve 344. The top of the second sleeve 353 passes through the bottom of the mounting base 361 and is rotatably connected to it via a bearing. The first bevel gear 362 is fitted onto the top of the second sleeve 353 and is fixedly connected to it. The first rotating rod 364 is disposed inside the mounting base 361, above the first bevel gear 362, and along the length of the mounting box 31, with both ends rotatably connected to the mounting base 361. The second bevel gear 363 is fitted onto one end of the first rotating rod 364 and is fixedly connected to it, and the first bevel gear 362 meshes with the second bevel gear 363. The second rotating rod 365 is arranged along the width direction of the mounting box 31, and one end of the second rotating rod 365 is sleeved on the first rotating rod 364 and fixedly connected thereto, while the other end is fixedly connected to the side of the body 1.

[0036] Clicking the second switch 19 activates the second cylinder 351, which in turn drives the second rack 352 to move. Since the second spur gear 354 meshes with the second rack 352, the second spur gear 354 rotates, causing the second sleeve 353 to rotate, which in turn drives the first bevel gear 362 to rotate. Since the first bevel gear 362 meshes with the second bevel gear 363, the second bevel gear 363 also rotates. Because the second bevel gear 363 is fixed to the first rotating rod 364, it also drives the first rotating rod 364 to rotate. Since one end of the second rotating rod 365 is fixed to the first rotating rod 364, the second rotating rod 365 rotates, thereby driving the body 1 to rotate, allowing the body 1 to tilt and adjust its angle.

[0037] Reference Figure 1 The fixing mechanism 4 includes a cover 41 and flanges (not shown in the figure). The cover 41 is hollow inside with an open bottom. The bottom end of the vertical plate 211 passes through the cover 41, extends into the cover 41, and is slidably connected to it. There are two flanges, which are set inside the cover 41 and correspond one-to-one with the two vertical plates 211. Each flange is fixed to the bottom end of its corresponding vertical plate 211 and is fixed to the ground by screws (not shown in the figure). In use, the entire device can be fixed by the flanges and screws.

[0038] The operating principle of this invention is as follows: First, the entire device is fixed using a flange. The user can select their height on the touchscreen 111. After receiving the command, the mainboard 11 sends a signal to the lifting mechanism 2, activating the first motor 221. This motor drives the main body 1 to adjust to a suitable height, and the touchscreen 111 will remain at that comfortable operating height. When the touchscreen 111 is reflective, the user can click the first switch 18 as needed. The first cylinder 342 drives the first rack 343 to move, which in turn rotates the first sprocket 345, causing the first sleeve 344 to rotate, thus achieving... The main body 1 can rotate horizontally; the second switch 19 can also be clicked to start the second cylinder 351, which will drive the second rack 352 to move, thus causing the second sprocket 354 to rotate, which in turn causes the second sleeve 353 to rotate. Since the first bevel gear 362 is fixed on the second sleeve 353, it will also drive the first bevel gear 362 to rotate. Since the first bevel gear 362 and the second bevel gear 363 are meshed, the second bevel gear 363 will also rotate, which will also drive the first rotating rod 364 and the second rotating rod 365 to rotate, ultimately realizing the adjustment of the angle of the main body 1, which is convenient for users.

[0039] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
