Description

Technical Field

[0001] The present application relates to the technical field of automatic lifters, and more specifically, to an automatic lifter and an automatic lifting lamp. Background Art

[0002] Automatic lifting lamps are widely used in various places that require high-altitude lighting due to their flexibility and efficiency. For example:

[0003] Factories and workshops: In factories and workshops, automatic lifting lamps can easily adjust the lighting height to meet the lighting needs of different work areas and equipment.

[0004] Gymnasiums and sports fields: In gymnasiums and sports fields, automatic lifting lamps can adjust the lighting angle and height according to the needs of competition or training to ensure good lighting effects.

[0005] Outdoor lighting: In outdoor places such as squares, parks, roads, etc., automatic lifting lamps can easily realize the lifting and adjustment of lighting equipment, improving lighting efficiency and safety.

[0006] Home lighting: In terms of home, it can be used for dining chandeliers, living room lights, ceiling lights, etc. Automatic lifting lamps can easily realize the lifting and adjustment of lighting equipment, improve lighting efficiency, and have both intelligence and safety.

[0007] The operating principle of automatic lift lamps relies primarily on the coordinated function of components such as the motor, transmission, control system, and safety devices. To adjust the lamp's height, the user issues a command via a remote control or control panel. Upon receiving the command, the control system activates the motor and converts the rotational force into a lifting motion through the transmission (e.g., gearbox, shaft, wires, etc.), thereby achieving the desired height adjustment.

[0008] Application number CN02203927.9 discloses an automatic lifting lamp, whose main feature is that the lamp panel is in the shape of a buckle basin, and a forward and reverse motor is installed in the buckle basin. A wire pulley is installed on the motor shaft, and a lifting rope is wound around the wire pulley. The lifting rope passes through the pulley to lift the lamp panel, and a limiter is also fixed on the motor housing.

[0009] Although the above-mentioned automatic lifting lamp realizes the lifting and lowering of the lamp panel through a motor, a pulley and a hanging rope, it has at least the following defects: its lifting switch is a multi-position switch, and when the dial button is in the middle, it is in the lifting positioning state, that is, when it is necessary to stop the lifting of the lamp panel, it is necessary to manually turn the multi-position switch so that the dial button of the multi-position switch is in the middle, that is, the power is disconnected, and when it is placed up or down (or left or right), it can be in the lifting state, that is, the motor is in the forward or reverse state. This makes it impossible to accurately control the lifting height of the lamp panel. For example, when the lamp panel is lifted to a specified height, multiple up and down adjustments need to be made through the multi-position switch.

[0010] Therefore, the existing technology needs to be improved. Utility Model Content

"Multiple" means two or more, unless otherwise clearly and specifically defined.

[0056] Example 1:

[0057] See also Figure 1 The present embodiment provides an automatic lifter, which includes a PLC controller 100, a driving component 200, a winding component 300, a first displacement sensing component 400 and a second displacement sensing component 500. The driving component 200 is electrically connected to the PLC controller 100, the winding component 300 is transmission-connected to the driving component 200, and an electric wire 700 is provided on the winding component 300. The first displacement sensing component 400 is electrically connected to the PLC controller 100, and the first displacement sensing component 400 is connected to the winding component 300. The first displacement sensing component 400 is used to monitor the number of rotations of the winding component 300. The second displacement sensing component 500 is electrically connected to the PLC controller 100, and the second displacement sensing component 500 is connected to the electric wire 700. The second displacement sensing component 500 is used to monitor the linear displacement of the electric wire 700.

[0058] In this example, see Figure 2 The wire 700 is wound around the winding component 300, and the driving component 200 is drivingly connected to the winding component 300. The driving component 200 can drive the winding component 300 to rotate, so that the winding component 300 winds or releases the wire 700, thereby achieving the up and down movement of the lamp (not shown in the figure) on the wire 700. For example, the driving component 200 can drive the winding component 300 to rotate forward, so that the winding component 300 releases the wire 700, or the driving component 200 can drive the winding component 300 to rotate reversely, so that the winding component 300 winds the wire 700.

[0059] Among them, when the driving component 200 drives the winding component 300 to rotate, the first displacement sensing component 400 can monitor the rotation of the winding component 300. For example, when the PLC controller 100 controls the driving component 200 to work according to the linear length set by the wire 700, the driving component 200 drives the winding component 300 to rotate. When the first displacement sensing component 400 detects that the winding component 300 rotates to the set number of revolutions, the first displacement sensing component 400 can feedback the rotation status of the winding component 300 to the PLC controller 100. The PLC controller 100 can adjust the working status of the driving component 200 in time, so that the driving component 200 stops driving the winding component 300.

[0060] At the same time, the second displacement sensing component 500 can monitor 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 driving 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.

[0061] For example, under normal circumstances, assuming that the winding component 300 rotates 3 circles and the wire 700 moves 1 meter, when the winding component 300 rotates 3 circles, the first displacement sensing component 400 detects that the winding component 300 rotates to the set number of revolutions of 3 circles. The first displacement sensing component 400 can feedback the rotation status of the winding component 300 to the PLC controller 100. At the same time, the second displacement sensing component 500 can detect that the wire 700 moves 1 meter. The PLC controller 100 controls the driving component 200 to stop driving the winding component 300, and the winding component 300 stops releasing the wire 700.

[0062] Abnormal situation 1, the winding component 300 rotates 2.5 circles (normal 3 circles), and the wire 700 moves 1 meter. When the first displacement sensing component 400 detects that the winding component 300 rotates to the set number of revolutions of 2.5 circles, the second displacement sensing component 500 can detect that the wire 700 moves 1 meter. The PLC controller 100 controls the driving component 200 to stop driving the winding component 300, and the winding component 300 stops releasing the wire 700 to prevent the winding component 300 from continuing to rotate, so that the winding component 300 stops releasing the wire 700.

[0063] Abnormal situation 2: the winding component 300 rotates 4 turns and the wire 700 moves 1 meter. When the first displacement sensing component 400 detects that the winding component 300 has rotated to the set number of turns 3, the second displacement sensing component 500 detects that the movement of the wire 700 has not reached 1 meter. The PLC controller 100 controls the driving component 200 to continue driving the winding component 300 until the second displacement sensing component 500 detects that the movement of the wire 700 reaches 1 meter, and the winding component 300 stops releasing the wire 700.

[0064] Among them, the PLC controller 100 can be understood as the existing technology, and the specific structure of the PLC controller 100 is not repeated any more.

[0065] Therefore, in this embodiment, the driving component 200 drives the winding component 300 to rotate, so that the wire 700 moves. The second displacement sensing component 500 can monitor the linear movement of the wire 700 and promptly feedback the linear movement of the wire 700, so that the PLC controller 100 can promptly adjust the working state of the driving component 200 to ensure the accuracy and stability of the linear movement of the wire 700.

[0066] Specifically, see Figure 3 The first displacement sensing assembly 400 includes: a reduction gear set 410 and a first displacement sensor 420. The reduction gear set 410 is transmission-connected to the winding component 300. The first displacement sensor 420 is connected to the reduction gear set 410. The first displacement sensor 420 is used to monitor the rotation of the reduction gear set 410 to monitor the rotation of the winding component 300.

[0067] In this embodiment, the reduction gear set 410 can be connected to the winding component 300 for transmission. When the winding component 300 rotates, the winding component 300 can drive the reduction gear set 410 to rotate. When the reduction gear set 410 rotates, the first displacement sensor 420 can monitor the rotation state of the reduction gear set 410. For example, assuming that the winding component 300 is wound with 6 turns of wire 700, the 6 turns of wire 700 total 2m, and the winding component 300 rotates 6 turns, the conveying gear of the reduction gear set 410 rotates 360°, and the first displacement sensor 420 is connected to the conveying gear, that is, within the range of one rotation of the conveying gear, the first displacement sensor 420 can monitor the rotation state of the winding component 300. The first displacement sensor 420 can determine the rotation state of the winding component 300 by monitoring the rotation angle of the conveying gear.

[0068] Optionally, the first displacement sensor 420 may include a potentiometer-type displacement sensor.

[0069] The first displacement sensor 420 may include a potentiometer displacement sensor, that is, the potentiometer displacement sensor is connected to the reduction gear set 410, and the potentiometer displacement sensor is used to monitor the rotation of the reduction gear set 410 to monitor the rotation of the winding component 300. For example, the potentiometer displacement sensor may be a resistive displacement sensor.

[0070] Specifically, see Figure 4 The reduction gear set 410 includes: a first transmission gear 430, a second transmission gear 440 and a third transmission gear 450. The first transmission gear 430 includes a coaxial first large gear portion 431 and a first small gear portion 432. The first large gear portion 431 is transmission-connected to the winding component 300. The second transmission gear 440 includes a coaxial second large gear portion 441 and a second small gear portion 442. The second large gear portion 441 is meshed and transmission-connected with the first small gear portion 432. The third transmission gear 450 includes a coaxial third large gear portion 451 and a third small gear portion 452. The third large gear portion 451 is meshed and transmission-connected with the second small gear portion 442. The third small gear portion 452 is connected to the first displacement sensor 420.

[0071] In this embodiment, the reduction gear group 410 achieves a deceleration effect through the first transmission gear 430, the second transmission gear 440 and the third transmission gear 450. The first displacement sensor 420 can accurately monitor the position and speed of the third small gear part 452 so as to accurately control the rotation of the winding component 300, which can provide a reliable basis for fault warning of the automatic lifter.

[0072] Specifically, see Figure 2 The driving assembly 200 includes: a driving motor 210, a reducer 220 and a driving mounting plate 230. The driving motor 210 is electrically connected to the PLC controller 100. The driving motor 210 is used to drive the winding component 300 to rotate. The reducer 220 is located between the driving motor 210 and the winding component 300. The reducer 220 is respectively connected to the driving motor 210 and the winding component 300.

[0073] In this embodiment, the drive motor 210 can drive the reducer 220 to rotate, and the reducer 220 can drive the winding component 300 to rotate. The drive motor 210 achieves a deceleration effect through the reducer 220, providing stable power for the efficient operation of the winding component 300. The drive mounting plate 230 is connected to the reducer 220, and the drive mounting plate 230 is used to mount the winding component 300. The drive motor 210 and the reducer 220 can be understood as existing technology, and the specific structures of the drive motor 210 and the reducer 220 are not repeated here.

[0074] Specifically, see Figure 3 and Figure 5 The winding component 300 includes: a winding shaft 310, an extension shaft 320, a winding gear 330 and a housing 370. The winding shaft 310 is transmission-connected to the reducer 220 of the driving assembly 200. The winding shaft 310 is provided with an electric wire 700. The extension shaft 320 extends outward from the winding shaft 310. The winding gear 330 is arranged on the extension shaft 320. The winding gear 330 is used to be transmission-connected to the first large gear portion 431 of the first displacement sensing assembly 400.

[0075] In this embodiment, the wire 700 is wound around the winding spool 310. An extension shaft 320 is provided on the side of the winding spool 310 away from the reducer 220. It can be understood that the winding spool 310 and the extension shaft 320 are concentric and coaxial, and the extension shaft 320 is provided with a winding gear 330, which is meshed and connected to the first large gear portion 431. When the drive motor 210 drives the reducer 220 to rotate, the reducer 220 drives the winding spool 310 to rotate. At the same time, the winding gear 330 on the extension shaft 320 can drive the first transmission gear 430 to rotate. The first transmission gear 430 drives the second transmission gear 440 to rotate. The second transmission gear 440 rotates and drives the third transmission gear 450. The third small gear portion 452 of the third transmission gear 450 is connected to the first displacement sensor 420 to achieve real-time monitoring of the rotation state of the winding component 300, thereby achieving high-precision control of the linear movement of the wire 700.

[0076] Housing 370 houses the winding assembly 300, the first displacement sensor assembly 400, and the second displacement sensor assembly 500. Housing 370 provides a favorable environment for the stable operation of the winding assembly 300 and includes a cable routing port through which the wires 700 pass. For example, housing 370 has two cavities: one for mounting the winding spool 310 and wires 700, and the other for mounting the reduction gear assembly 410 and the first displacement sensor 420. The reduction gear assembly 410 is located outside the winding spool 310. Housing 370 is provided with a cover 371 for easy removal and maintenance of the reduction gear assembly 410.

[0077] Specifically, see Figure 3 and Figure 5 The winding component 300 also includes: a group of baffles 340 and an elastic pressing piece 350, the baffles 340 are arranged on the winding shaft 310, and the group of baffles 340 are connected to the winding shaft 310 to form an accommodating groove 341 for accommodating the wire 700, and the elastic pressing piece 350 is located in the accommodating groove 341, and the elastic pressing piece 350 is used to abut against the wire 700.

[0078] In this embodiment, a group of baffles 340 are connected to the winding shaft 310 to form a receiving groove 341. The receiving groove 341 can arrange the winding and releasing of the wire 700 to ensure the smooth movement of the wire 700. The elastic pressing piece 350 is used to press the wire 700, which can provide a good and stable environment for the movement of the wire 700.

[0079] Specifically, see Figure 5 The winding component 300 further includes a spiral groove 360 ​​, which is disposed on the surface of the winding shaft 310 and is used to cooperate with the wire 700 for connection.

[0080] In this embodiment, when the wire 700 is wound around the winding shaft 310, the wire 700 is embedded in the spiral wire groove 360. The spiral wire groove 360 ​​can make the wire 700 more neatly distributed on the winding shaft 310. When the wire 700 is released, the wire 700 can be arranged in an orderly and stable manner along the spiral wire groove 360, or, when the winding shaft 310 is driven to wind the wire 700, the wire 700 can be wound in sequence and in an orderly manner along the spiral wire groove 360 ​​to ensure the stable movement of the wire 700.

[0081] Specifically, see Figure 2 , further comprising: a tensioner 600 , which is connected to the output end of the wire 700 .

[0082] In this embodiment, the housing 370 has a wire arrangement port, and the wire 700 passes through the wire arrangement port. The wire tensioner 600 can prevent the wire 700 from being entangled in the wire arrangement port. The wire tensioner 600 is connected to the output end of the wire 700. The wire tensioner 600 is used to clamp the wire 700 to ensure stable operation of the wire 700. For example, when the wire 700 is released, the wire tensioner 600 can clamp the wire 700 so that the wire 700 is discharged from the wire arrangement port in an orderly and stable manner, or, when the winding shaft 310 is driven to wind the wire 700, the wire tensioner 600 can clamp the wire 700 so that the wire 700 is retracted in an orderly and stable manner.

[0083] Specifically, see Figure 6 The wire tensioner 600 includes: a fixed pulley 610, a movable pulley 620 and a rope tightening housing 640. The fixed pulley 610 and the movable pulley 620 are connected to form a clamping space 630. The clamping space 630 is located on the side of the wire 700 close to the output end. The clamping space 630 is used to clamp the wire 700. The rope tightening housing 640 is used to install the fixed pulley 610 and the movable pulley 620.

[0084] In this embodiment, the fixed pulley 610 is connected to the movable pulley 620 to form a clamping space 630, through which the wire 700 passes. The movable pulley 620 can be connected to a micromotor. For example, when the drive motor 210 drives the winding shaft 310 to rotate, the winding shaft 310 releases the wire 700 by rotating. At the same time, the micromotor drives the movable pulley 620 to rotate. At this time, the movable pulley 620 can drive the wire 700 to be released from the wire arranging port. At the same time, the wire 700 drives the fixed pulley 610 to rotate, thereby preventing the wire 700 from being entangled in the wire arranging port.
