Description

Technical Field

[0001] This utility model belongs to the field of cable reel technology, specifically relating to an intelligent energy-saving reel. Background Technology

[0002] In mobile device power supply scenarios, traditional cable reels often use hysteresis couplings for driving, which suffers from low control accuracy, high noise, and high energy consumption. Existing technologies struggle to balance cable winding force control with energy-saving requirements and rely on complex communication systems for follow-up control, leading to cable damage and slack.

[0004] The reel body, with one side mounted on the base;

[0005] Flat cable, which is wound around the outside of the reel body;

[0006] The distribution box is mounted on the side of the base via a distribution box support plate.

[0007] Preferably, it also includes a slip ring, which is fixed to the axis of the reel body by a slewing bearing and connected to the inner cable head of the flat cable;

[0008] The outer gear ring of the slewing bearing is fixed to the reel body, and its inner ring is fixed to the base;

[0009] It also includes a motor assembly mounted on the base, wherein a first gear is mounted on the output end of the motor assembly, and the first gear meshes with the outer gear ring of the slewing bearing.

[0010] Preferably, a limiting piece is welded onto the outer shell of the slider, and the limiting piece has a slot.

[0011] The inner ring of the slewing bearing is fixed with a limit rod, which is engaged in the slot.

[0012] Preferably, a multi-functional travel limiter is also installed on the top of the base, and the input shaft of the multi-functional travel limiter is provided with a second gear, which meshes with the outer gear ring of the slewing bearing.

[0013] The beneficial effects of this utility model are:

[0014] A multi-functional travel limit switch provides feedback on the cable's winding and unwinding limits, stopping the motor promptly to prevent over-winding or over-unwinding. An angle encoder provides reel angle feedback, controlling the drive current in real time to precisely manage the cable winding force, achieving energy savings on the reel and extending cable lifespan.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1 to 3 As shown, this embodiment provides an intelligent energy-saving reel, including:

[0025] The reel body 1 is mounted on one side of the base 2; the flat cable 3 is wound around the outside of the reel body 1, and is a highly flexible flat cable. It is wound evenly along the spiral groove of the reel body 1, and its inner cable end passes through the reel shaft hole and connects to the spindle of the slip ring 5; the distribution box 4 is mounted on the side of the base 2 through the distribution box support plate. It integrates a frequency converter, circuit breaker and wiring terminals for power distribution and drive control of the motor assembly 7.

[0026] It also includes a slip ring 5, which is fixed to the axis of the reel body 1 by a slewing bearing 6. The slip ring 5 consists of a spindle and a shell. The inner spindle is connected to the inner cable head of the flat cable 3, and the end face of the spindle has a flange connected to the reel body 1. The outer gear ring of the slewing bearing 6 is connected to the flange of the reel body 1 by high-strength bolts, and the inner ring is interference-fitted with the bushing of the base 2 to form a rigid support. Therefore, the spindle of the slip ring 5, the outer gear ring of the slewing bearing 6, and the reel body 1 will rotate together. It also includes a motor assembly 7, which is mounted on the base 2 and electrically connected to the distribution box 4. The motor assembly 7 is driven by a servo motor through a reducer to drive the reel. Its output end is connected to a first gear 8 through a flat key. The first gear 8 meshes with the outer gear ring of the slewing bearing 6 to achieve transmission. The transmission ratio is set to 1:15 to achieve speed reduction and torque increase. Meanwhile, the servo motor integrates an angle encoder to monitor the rotation angle of the reel in real time and output analog signals to the distribution box 4, forming a closed-loop control system: the distribution box 4 controls the magnitude of the drive current in real time according to the deviation between the target angle and the actual angle, and dynamically adjusts the output torque and speed of the motor assembly 7 to improve the positioning accuracy and winding force of the reel cable winding.

[0027] A limiting piece 9 is welded onto the outer shell of the slip ring 5, and the limiting piece 9 has a slot 10. A limiting rod 11 is fixed to the inner ring of the slewing bearing 6, and the limiting rod 11 is engaged in the slot 10 to prevent the outer shell of the slip ring 5 from rotating together, thereby preventing the cable at the rear end of the outer shell of the slip ring 5 from twisting into a strand as it rotates, which would affect the working efficiency and usage process of the reel.

[0028] A multi-functional travel limiter 12 is also installed on the top of the base 2, and is electrically connected to the distribution box 4. The input shaft of the multi-functional travel limiter 12 is equipped with a second gear 13, which meshes with the outer gear ring of the slewing bearing 6. The multi-functional travel limiter 12 has a built-in overload protection module and a double limit switch that match the input shaft. It judges the motor load status by the change in torque on the input bearing. When an abnormal torque is detected, such as gear jamming causing a sudden increase in resistance, the module will immediately output an analog signal to the distribution box 4 to achieve automatic shutdown, avoid motor stall and burnout, and achieve high-precision control and energy saving.

[0029] All the devices selected in this application (parts whose specific structures are not specified) are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
