[0052] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0054] Please see Figure 1This embodiment provides an automatic lifting mechanism, which includes: a PLC controller 100, a drive assembly 200, a winding component 300, a reduction gear set 410, and a first displacement sensor 400. The drive assembly 200 is electrically connected to the PLC controller 100. The winding component 300 includes: a winding shaft 310 and a plurality of coils 350 arranged in parallel on the winding shaft 310. The winding shaft 310 is drive-connected to the drive assembly 200. Each of the coils 350 contains an electric wire 700 that rotates with the winding shaft 310. The reduction gear set 410 is drive-connected to the winding shaft 310. The first displacement sensor 400 is connected to the reduction gear set 410 and is used to monitor the rotation of the reduction gear set 410 to monitor the number of rotations of the winding shaft 310.

[0055] In this embodiment, please refer to Figure 2 and Figure 5 The winding component 300 includes a winding shaft 310 and several coils 350 arranged side-by-side on the winding shaft 310. Each coil 350 contains an independent wire 700. When the drive assembly 200 drives the winding shaft 310 to rotate, the wires 700 in each coil 350 can rotate with the winding shaft 310, allowing the winding shaft 310 to wind or unwind the wires 700. The ends of the wires 700 can be connected to a lamp 800, thereby enabling several wires 700 to synchronously drive the lamp 800 to move up and down. For example, the drive assembly 200 can drive the winding shaft 310 to rotate clockwise, causing each coil 350 to synchronously unwind the wires 700; or, the drive assembly 200 can drive the winding shaft 310 to rotate counterclockwise, causing each coil 350 to synchronously wind the wires 700.

[0056] The PLC controller 100 is electrically connected to the drive assembly 200 and the first displacement sensor 400. The reduction gear set 410 is driven by the winding shaft 310. The first displacement sensor 400 is connected to the reduction gear set 410 and is used to monitor the rotation of the reduction gear set 410. For example, the winding shaft 310 can be wound with 6 turns of wire 700. The first displacement sensor 400 can monitor the rotation of the reduction gear set 410 within 360°. The rotation angle of the reduction gear set 410 corresponds to the length of the wire 700. That is, the required rotation angle of the reduction gear set 410 can be calculated based on the linear length of the wire 700. When the reduction gear set 410 reaches the required rotation angle, the first displacement sensor 400 can provide feedback to the PLC controller 100 so that the PLC controller 100 can control the drive assembly 200 to achieve precise control of the release or winding of the wire 700.

[0057] For example, when the PLC controller 100 controls the drive assembly 200 to operate according to the linear length set by the wire 700, the drive assembly 200 drives the winding shaft 310 to rotate. The winding shaft 310 drives each wire reel 350 to release the wire 700 synchronously. At the same time, the winding shaft 310 drives the reduction gear set 410 to rotate. The first displacement sensor 400 can monitor the rotation angle of the reduction gear set 410. When the reduction gear set 410 rotates to the required rotation angle, the first displacement sensor 400 can feed back the rotation state of the reduction gear set 410 to the PLC controller 100, that is, the reduction gear set 410 has reached the required rotation angle. The PLC controller 100 can then adjust the working state of the drive assembly 200 in time, so that the drive assembly 200 stops driving the winding shaft 310, and each wire reel 350 stops releasing the wire 700 synchronously. Compared with the existing lifting pneumatic rod, the automatic lifting mechanism in this embodiment has a simple structure, low cost, and small space occupation, making it suitable for indoor decorative lighting.

[0058] In this embodiment, the drive assembly 200 drives the winding component 300 to rotate, causing the winding shaft 310 to wind or release the wire 700. The winding shaft 310 is connected to the first displacement sensor 400 through the reduction gear set 410. The first displacement sensor 400 can detect the linear movement of the wire 700, enabling the PLC controller 100 to accurately control the rotation of the winding shaft 310, thereby achieving precise control of the linear movement of the wire 700 and thus enabling precise control of the lifting and lowering of the lamp 800. The structure is simple and the cost is low.

[0059] Optionally, the winding shaft 310 is provided with two or three coils 350 arranged side by side.

[0060] For example, please combine Figure 2 and Figure 3 The winding shaft 310 can have two coils 350 arranged side by side. Each coil 350 has an independent wire 700. When the winding shaft 310 rotates, it can drive the two wires 700 to rotate synchronously, so that each coil 350 releases or winds the wire 700 synchronously. For example, a long strip lamp 800 may include a long strip bracket 810, which can be suspended by two wires 700. The two wires 700 are respectively placed in the two coils 350 arranged side by side on the winding shaft 310. By driving the winding shaft 310 to rotate, the two wires 700 can synchronously drive the long strip bracket 810 to move up and down smoothly.

[0061] Please combine Figure 2 and Figure 4The winding shaft 310 may have three coils 350 arranged in parallel. Each coil 350 has an independent wire 700. When the winding shaft 310 rotates, it can drive the three wires 700 to rotate synchronously, so that each coil 350 releases or winds the wire 700 synchronously. A ring lamp 800 may include a ring bracket 820, which can be suspended by three wires 700. The three wires 700 are respectively placed in the three coils 350 arranged in parallel on the winding shaft 310. By driving the winding shaft 310 to rotate, the three wires 700 can synchronously drive the ring bracket to rise and fall smoothly. It should be understood that the number of coils 350 on the winding shaft 310 is not limited to the two or three mentioned above. The number of coils 350 on the winding shaft 310 can also be other cases, which are not limited here.

[0062] Specifically, please combine Figure 2 and Figure 7 The winding component 300 also includes an extension shaft 320 and a winding gear 330. The extension shaft 320 extends outward from the winding shaft 310, and the winding gear 330 is disposed on the extension shaft 320. The winding gear 330 is used to mesh and drive with the reduction gear set 410.

[0063] In this embodiment, the winding gear 330 is disposed on the extension shaft 320, which extends outward from the winding shaft 310. This can be understood as the winding shaft 310 and the extension shaft 320 being concentric and coaxial. The winding gear 330 is mounted on the extension shaft 320 and meshes with the reduction gear set 410 for transmission. When the drive assembly 200 drives the winding shaft 310 to rotate, the winding gear 330 on the extension shaft 320 simultaneously drives the reduction gear set 410 to rotate. The reduction gear set 410 is connected to the first displacement sensor 400, which can monitor the rotational state of the reduction gear set 410, thereby achieving high-precision control of the linear movement of the wire 700.

[0064] Specifically, please refer to Figure 6 The reduction gear set 410 includes a first transmission gear 420, a second transmission gear 430, and a third transmission gear 440. The first transmission gear 420 includes a coaxial first large gear part 421 and a first small gear part 422. The first large gear part 421 is meshed and connected to the rope winding gear 330. The second transmission gear 430 is meshed and connected to the first small gear part 422. The third transmission gear 440 is meshed and connected to the second transmission gear 430. The third transmission gear 440 is connected to the first displacement sensor 400.

[0065] When the drive assembly 200 drives the winding shaft 310 to rotate, the winding gear 330 can drive the first large gear part 421 to rotate. The first small gear part 422 of the first transmission gear 420 drives the second transmission gear 430 to rotate. The rotation of the second transmission gear 430 drives the third transmission gear 440. The third transmission gear 440 is connected to the first displacement sensor 400. The first displacement sensor 400 can monitor the rotation state of the third transmission gear 440, realize real-time monitoring of the rotation state of the winding shaft 310, and thus realize high-precision control of the linear movement of the wire 700.

[0066] Specifically, please refer to Figure 5 The winding component 300 further includes a plurality of spaced baffles 340, which are connected to the winding shaft 310 and are used to form a coil 350.

[0067] In this embodiment, several spaced baffles 340 are connected to the winding shaft 310 to form several coils 350. For example, two adjacent baffles 340 can form a receiving groove 341 for accommodating the wire 700. The receiving groove 341 is equivalent to the coil 350. The coil 350 can arrange the winding and unwinding of the wire 700, avoid mutual interference between the wires 700, ensure the smooth movement of the wire 700, and provide a good and stable environment for the movement of the wire 700.

[0068] Specifically, please refer to Figure 1 and Figure 2 The automatic lifting mechanism also includes a rope tensioner 600 and a second displacement sensor 500. The rope tensioner 600 is connected to the wire 700, and the second displacement sensor 500 is electrically connected to the PLC controller 100 and the wire 700. The second displacement sensor 500 is used to monitor the linear displacement of the wire 700.

[0069] In this embodiment, the tensioner 600 can prevent the wire 700 from getting tangled in the cable tray. The tensioner 600 is connected to the output end of the wire 700 and is used to clamp the wire 700 to ensure stable operation of the wire 700. For example, when the wire 700 is released, the tensioner 600 can clamp the wire 700 so that the wire 700 is discharged from the cable tray in an orderly and stable manner. Alternatively, when the drive winding shaft 310 winds the wire 700, the tensioner 600 can clamp the wire 700 so that the wire 700 is retracted in an orderly and stable manner.

[0070] The second displacement sensor 500 can detect the linear movement of the wire 700 and feed back the linear movement of the wire 700 to the PLC controller 100. The PLC controller 100 can adjust the working state of the drive component 200 according to the movement state of the wire 700, so that the linear movement of the wire 700 is consistent with the set linear length, thereby ensuring the accuracy and stability of the linear movement of the wire 700.

[0071] For example, under normal circumstances, assuming the winding shaft 310 rotates 3 times and the wire 700 moves 1m, when the winding component 300 rotates 3 times, the first displacement sensor 400 detects that the winding shaft 310 has rotated to the set number of rotations of 3 times. The first displacement sensor 400 can feed back the rotation status of the winding shaft 310 to the PLC controller 100. At the same time, the second displacement sensor 500 can detect that the wire 700 has moved 1m. The PLC controller 100 controls the drive component 200 to stop driving the winding shaft 310, and the winding shaft 3100 stops releasing the wire 700.

[0072] Abnormal situation 1: The winding shaft 310 rotates 2.5 revolutions (normally 3 revolutions), and the wire 700 moves 1m. When the first displacement sensor 400 detects that the winding shaft 310 has rotated to the set number of revolutions of 2.5 revolutions, the second displacement sensor 500 can detect that the wire 700 has moved 1m. The PLC controller 100 controls the drive component 200 to stop driving the winding shaft 310, and the winding shaft 310 stops releasing the wire 700 to prevent the winding shaft 310 from continuing to rotate, thus stopping the release of the wire 700.

[0073] Abnormal situation 2: The winding shaft 310 rotates 4 times and the wire 700 moves 1m. When the first displacement sensor 400 detects that the winding shaft 310 has rotated to the set number of rotations of 3 times, the second displacement sensor 500 detects that the wire 700 has not moved 1m. The PLC controller 100 controls the drive component 200 to continue driving the winding shaft 310 until the second displacement sensor 500 detects that the wire 700 has moved 1m, at which point the winding shaft 310 stops releasing the wire 700.

[0074] The PLC controller 100 can be understood as existing technology, and the specific structure of the PLC controller 100 will not be described in detail.

[0075] Specifically, please refer to Figure 5 The rope tensioner 600 includes a fixed pulley 610, a movable pulley 620, and a rope tensioning shell 640. The fixed pulley 610 and the movable pulley 620 are connected to form a clamping space 630, which is used to clamp the wire 700.

[0076] The fixed pulley 610 and the movable pulley 620 are connected to form a clamping space 630 through which the wire 700 passes. The movable pulley 620 can be connected to a micro motor. For example, when the drive assembly 200 drives the winding shaft 310 to rotate, the winding shaft 310 releases the wire 700 by rotating. At the same time, the micro motor drives the movable pulley 620 to rotate, at which time the movable pulley 620 can drive the wire 700 to be released from the cable outlet. At the same time, the wire 700 drives the fixed pulley 610 to rotate, which can prevent the wire 700 from getting tangled in the cable outlet. The tensioning shell 640 is used to install the fixed pulley 610 and the movable pulley 620. The tensioning shell 640 can provide a good environment for the rotation of the fixed pulley 610 and the movable pulley 620, and prevent other wires from getting tangled or blocked.

[0077] Optionally, the second displacement sensor 500 includes a roller encoder connected to the movable pulley 620. The roller encoder is used to monitor the rotation of the movable pulley 620 to achieve linear movement of the monitoring wire 700.

[0078] In this embodiment, the second displacement sensor 500 can be a roller encoder to monitor the linear movement of the wire 700. For example, the roller encoder can be connected to the movable pulley 620, and the rotation of the movable pulley 620 can be monitored by the roller encoder to monitor the linear movement of the wire 700, thereby monitoring the movement length of the wire 700.

[0079] Optionally, the first displacement sensor 400 may include a potentiometer-type displacement sensor, that is, the potentiometer-type displacement sensor is connected to the reduction gear set 410, and the potentiometer-type displacement sensor is used to monitor the rotation of the reduction gear set 410 to realize the monitoring of the rotation of the winding shaft 310. For example, the potentiometer-type displacement sensor may be a resistive displacement sensor.

[0080] Specifically, please refer to Figure 2 The drive assembly 200 may include a drive motor 210 and a reducer 220. The drive motor 210 is drivenly connected to the reducer 220, and the reducer 220 is drivenly connected to the winding shaft 310. The winding shaft 310 has a first reel 351, a second reel 352, and a third reel 353 arranged in parallel. The first reel 351 has a first wire 710 that rotates with the winding shaft 310; the second reel 352 has a second wire 720 that rotates with the winding shaft 310; and the third reel 353 has a third wire 730 that rotates with the winding shaft 310.

[0081] Please see Figure 5The winding component 300 also includes a housing 360, which covers the outer sides of the first reel 351, the second reel 352, and the third reel 353. The outer periphery of the housing 360 is evenly provided with a first outlet, a second outlet, and a third outlet. The first outlet is used for routing the first wire 710, the second outlet for routing the second wire 720, and the third outlet for routing the third wire 730. Guide pulleys 362 are provided on the side of the first wire 710 near the first outlet, the side of the second wire 720 near the second outlet, and the side of the third wire 730 near the third outlet. The first wire 710 is connected to the tensioner 600 after passing through the guide pulleys 362. A cover plate 361 is provided on the housing 360 to facilitate the disassembly and maintenance of the reduction gear set 410.

[0082] In this embodiment, the drive motor 210 drives the reducer 220 to rotate, and the reducer 220 can drive the winding shaft 310 to rotate. The winding shaft 310 can drive the first wire 710, the second wire 720, and the third wire 730 to be wound or unwound synchronously. The ends of the first wire 710, the second wire 720, and the third wire 730 can be connected to the lamp 800. In this way, the winding shaft 310 can control the linear movement of the first wire 710, the second wire 720, and the third wire 730 synchronously to control the lifting and lowering of the lamp 800. For example, the lamp 800 can be a ring lamp 800, and the first wire 710, the second wire 720, and the third wire 730 can be evenly arranged on the ring lamp 800, so that the ring lamp 800 can be lifted and lowered smoothly.

[0083] Guide pulleys 362 are provided on the side of the first wire 710 near the first outlet, the side of the second wire 720 near the second outlet, and the side of the third wire 730 near the third outlet. Here, the wires 700 change their direction of movement through the guide pulleys 362, so that the first wire 710, the second wire 720, and the third wire 730 can be suspended on the winding shaft 310.

[0084] The rope tensioner 600 may include a fixed pulley 610 and a movable pulley 620. The rope tensioner 600 is located on the side of the first outlet. The rope tensioner 600 has the function of clamping the first wire 710 to prevent the first wire 710 from getting tangled or blocked at the first outlet.

[0085] A second displacement sensor 500 can be installed on one side of the tensioner 600. The second displacement sensor 500 is used to monitor the rotation of the movable pulley 620 in order to monitor the linear movement of the first wire 710, and thus monitor the moving length of the first wire 710. Since the first wire 710, the second wire 720 and the third wire 730 can be understood to move synchronously up and down, it is understood that a second displacement sensor 500 is set to monitor the first wire 710. It should also be understood that a second displacement sensor 500 can be set to monitor the linear movement of the second wire 720 and the third wire 730.

[0086] Example 2:

[0087] This embodiment provides an automatic lifting light fixture, which includes the automatic lifting mechanism as described in the above embodiment. Therefore, this automatic lifting light fixture possesses all the features and beneficial effects of the aforementioned automatic lifting mechanism, which will not be elaborated further.

[0088] In summary, this application discloses an automatic lifting mechanism and an automatic lifting lamp. The automatic lifting mechanism includes a PLC controller, a drive assembly, a winding component, a reduction gear set, and a first displacement sensor. The drive assembly is electrically connected to the PLC controller. The winding component includes a winding shaft and several coils arranged parallel to the winding shaft. The winding shaft is drive-connected to the drive assembly. Each coil contains an electric wire that rotates with the winding shaft. The reduction gear set is drive-connected to the winding shaft. The first displacement sensor is connected to the reduction gear set and monitors the rotation of the reduction gear set to monitor the number of rotations of the winding shaft. This application drives the winding component to rotate via the drive assembly, causing the winding shaft to wind or release the electric wire. The winding shaft is connected to the first displacement sensor via the reduction gear set, allowing the first displacement sensor to monitor the linear movement of the electric wire. This enables the PLC controller to precisely control the rotation of the winding shaft, thereby achieving precise control of the linear movement of the electric wire and ultimately precise control of the lamp's lifting. The mechanism is simple in structure, low in cost, and occupies little space, making it suitable for indoor decorative lighting.

[0089] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
