Description

Technical Field

[0001] This application relates to the field of cable reel technology, and more particularly to a cable reel device and cable reel. Background Technology

[0002] Conductive wires are widely used in daily life, but due to their varying lengths and tendency to tangle, storage and organization are often inconvenient. To solve this problem, cable reel devices with cable retraction functions have been introduced to the market, making it easier for users to store and use conductive wires.

[0045] Please refer to the following: Figures 1 to 8 The first embodiment of this application provides a winding device 10 for retrieving and releasing a conductive wire 11. The winding device 10 includes a fixed housing 12, an internal gear disc 13, a gear disc 132, a reduction motor 14, a movable wheel 1322, a fixed wheel 1323, the conductive wire 11, a sealed housing 15, and a control circuit board 16. An inner groove 121 is provided in the middle of the fixed housing 12, and the internal gear disc 13 is sleeved on the outer groove wall 1212 of the fixed housing 12 via a sleeve 131. A movable wheel 1322 and a fixed wheel 1323 are respectively provided on the gear disc 132. The movable wheel 1322 meshes with the fixed wheel 1323 and forms a transmission relationship with the motor main wheel 1214. The reduction motor 14 is fixed to the inner groove wall 1211 of the fixed housing 12, and its rotating shaft 1213 passes through the main wheel hole 1326 and is connected to the motor main wheel 1214. The control circuit board 16 is installed at the bottom of the outer groove wall 1212 and is electrically connected to the geared motor 14 and the control button 111.

[0046] During operation, the geared motor 14 drives the motor main wheel 1214 to rotate. The motor main wheel 1214 meshes with the movable wheel 1322 and transmits power, causing the movable wheel 1322 to rotate. The movable shaft 1333 of the movable wheel 1322 is located in the movable hole 1327 and moves along the movable hole 1327 under the thrust of the motor main wheel 1214. When the motor main wheel 1214 rotates clockwise, the movable shaft 1333 of the movable wheel 1322 moves from the lower separating section 1332 to the upper engaging section 1330. The movable wheel 1322 meshes with the fixed wheel 1323, forming a multi-stage transmission. The fixed wheel 1323 drives the inner gear disk 13 to rotate by meshing with several rotating teeth 1324. The conductive wire 11 is wound around the outer side of the sleeve 131, realizing the recovery of the conductive wire 11. When the motor main wheel 1214 rotates counterclockwise, the movable shaft 1333 of the movable wheel 1322 moves from the upper engagement section 1330 to the lower disengagement section 1332. The movable wheel 1322 disengages from the fixed wheel 1323, and the inner gear disc 13 is no longer driven by the fixed wheel 1323. The conductive wire 11 can be freely pulled out, realizing the release of the conductive wire 11. The winding device 10 adopts a multi-stage transmission structure combining the inner gear disc 13 and the reduction motor 14, which makes the winding of the conductive wire 11 more efficient, and avoids the problem of excessive lateral size caused by the parallel arrangement of the wire disc and the motor 142 in traditional winding devices. The fixed housing 12 is provided with an inner groove 121, in which the outer groove wall 1212 provides stable support for the inner gear disc 13, allowing the inner gear disc 13 to rotate within the fixed housing 12.

[0047] Compared to traditional winding devices, the winding device 10 allows the inner gear disc 13 to be partially embedded within the fixed housing 12, rather than being completely exposed, thus reducing the overall lateral space occupied by the device. The winding device 10 employs a multi-stage transmission structure where the inner gear disc 13 interacts with the reduction motor 14. Specifically, the main wheel 1214 of the reduction motor 14 transmits torque sequentially through the movable wheel 1322, the fixed wheel 1323, and several rotating teeth 1324 on the inner side of the gear disc 132, ultimately driving the inner gear disc 13 to rotate and retract the conductive wire 11. Compared to the traditional method of the motor 142 directly driving the spool, the winding device 10 reduces the dependence on the outer diameter of the spool, allowing the conductive wire 11 to be tightly wound around the outer surface of the sleeve 131, further reducing the overall lateral dimension of the winding clutch device. The reduction motor 14 is compactly mounted on the inner groove wall 1211, i.e., inside the fixed housing 12, unlike existing technologies where the motor 142 is placed side-by-side next to the spool. The internal space utilization has been optimized, allowing the motor 142, gear disk 132 and conductive wire 11 storage structure to complete the functions that originally required more space in a smaller volume, further reducing the lateral size of the overall device.

[0048] The stable torque transmission is achieved through the cooperation of the movable wheel 1322, the motor main wheel 1214, and the fixed wheel 1323, enabling the entire device to achieve efficient storage of the conductive wire 11 while maintaining a compact size. The engaging structure of the fixed housing 12 and the sealed housing 15 ensures the stability of the gear disk 132 and transmission components, while also facilitating assembly and maintenance. Through the cooperation of the control circuit board 16 and the control button 111, users can precisely control the retraction and release of the conductive wire 11, making the device more practical and convenient.

[0049] Please refer to the following: Figures 1 to 2 In some embodiments, the winding device 10 includes a conductive wire 11, a fixed housing 12, an internal gear disc 13, and a reduction motor 14; the fixed housing 12 has an inner groove 121 in the middle; the inner groove 121 has an inner groove wall 1211 and an outer groove wall 1212; the internal gear disc 13 has a sleeve 131 and a gear disc 132 arranged opposite to each other; the sleeve 131 is sleeved on the outer groove wall 1212; the gear disc 132 has a movable wheel 1322 and a fixed wheel 1323; the movable wheel 1322 meshes with the fixed wheel 1323. The conductive wire 11 is wound around the outer surface of the sleeve 131; the reduction motor 14 is fixedly installed in the inner groove wall 1211, and the rotating shaft 1213 of the reduction motor 14 extends from the gear disk 132. The rotating shaft 1213 is equipped with a motor main wheel 1214; the motor main wheel 1214 meshes with the movable wheel 1322; wherein, the inner sidewall of the gear disk 132 is provided with a plurality of rotating teeth 1324, and the fixed wheel 1323 meshes with the plurality of rotating teeth 1324, driving the inner gear disk 13 to rotate and retract the conductive wire 11. This effectively solves the problem of the large overall lateral size of the reel in the prior art, making it more compact and portable. The reduction motor 14 is compactly installed in the inner groove wall 1211, that is, inside the fixed housing 12, instead of being arranged side by side next to the reel as in the prior art. The internal space utilization has been optimized, allowing the motor 142, gear disk 132, internal gear disk 13 and conductive wire 11 to perform functions that originally required more space in a smaller volume, further reducing the lateral size of the overall device.

[0050] Please refer to the following: Figures 2 to 3In some embodiments, the gear disk 132 is provided with a disk body 1325, a main wheel hole 1326, a movable hole 1327, and a fixed wheel hole 1328; the disk body 1325 is fixedly mounted on the gear disk 132; a semi-enclosed frame 1329 is provided on the disk body 1325, the semi-enclosed frame 1329 being integrally formed with the disk body 1325; a plurality of snap fasteners 1334 are provided on the outer side of the semi-enclosed frame 1329; the main wheel hole 1326 is provided on the disk body 1325, and the rotating shaft 1213 extends from the main wheel hole 1326; the motor main wheel 1214 is mounted on... Above the main wheel hole 1326; the movable hole 1327 is disposed on the wheel body 1325, with the main wheel hole 1326 and the movable hole 1327 spaced apart; the movable shaft 1333 of the movable wheel 1322 moves in the movable hole 1327; the fixed wheel hole 1328 is disposed on the wheel body 1325, with the fixed wheel hole 1328 and the movable hole 1327 spaced apart. Furthermore, by adding a semi-enclosed frame 1329 and fixing it with a snap-fit ​​buckle 1334, the movable wheel 1322, fixed wheel 1323, motor main wheel 1214, and other components are more stably mounted on the wheel body 1325. This further improves the overall structural strength of the gear disc 132 and ensures that the relative positions of the gears do not misalign, avoiding problems with poor wire winding due to poor meshing, and improving the durability and reliability of the device.

[0051] Please refer to the following: Figure 3 In some embodiments, the movable hole 1327 includes an upper closing section 1330, a corner section 1331, and a lower separating section 1332. The corner section 1331 is used to prevent the movable shaft 1333 from sliding from the upper closing section 1330 to the lower separating section 1332 when the upper closing section 1330 rotates. When it is necessary to retract the conductive wire 11, the motor main wheel 1214 rotates clockwise, and the movable shaft 1333 moves from the lower separating section 1332 to the upper closing section 1330, driving the internal gear disk 13 to rotate. When it is necessary to release the conductive wire 11... At time 1, the motor main wheel 1214 rotates counterclockwise, and the movable shaft 1333 moves from the upper engaging section 1330 to the lower disengaging section 1332, disconnecting the connection between the movable wheel 1322 and the fixed wheel 1323. This allows the movable shaft 1333 to smoothly enter the upper engaging section 1330 and engage with the fixed wheel 1323 when the reduction motor 14 drives the retraction of the conductive wire 11, thus achieving power transmission. During wire release, the movable shaft 1333 can smoothly move to the lower disengaging section 1332, disconnecting the movable wheel 1322 from the fixed wheel 1323. This effectively prevents the movable shaft 1333 from slipping under normal operating conditions, ensuring the stability of the clutch mechanism, optimizing the wire retraction and release process, and improving the reliability of the device.

[0052] Please refer to the following: Figures 6 to 7 In some embodiments, a plurality of sliding protruding rings 1311 are provided on the end face of the sleeve 131 that abuts against the outer groove wall 1212, and all of the sliding protruding rings 1311 abut against the outer groove wall 1212; the plurality of sliding protruding rings 1311 are used to reduce the rotational friction between the inner gear disk 13 and the inner groove 121. This reduces the rotational friction between the inner gear disk 13 and the inner groove 121, making the rotation of the inner gear disk 13 smoother. This not only reduces energy loss and improves the winding efficiency, but also reduces wear on the gear disk and extends the service life of the device.

[0053] Please refer to the following: Figures 1 to 2 In some embodiments, a circular partition 1312 is fitted onto the end of the sleeve 131 away from the gear disk 132, forming a wire storage cavity between the circular partition 1312 and the gear disk 132. This wire storage cavity is used to store the conductive wire 11. Furthermore, by forming a wire storage cavity between the sleeve 131 and the gear disk 132, additional space is provided for storing the conductive wire 11. This effectively avoids the conductive wire 11 being piled up too tightly during storage, thus preventing damage due to excessive winding and further improving the durability and storage convenience of the conductive wire 11.

[0054] Please refer to the following: Figures 1 to 2 In some embodiments, the geared motor 14 includes a reducer 141 and a motor 142. One end of the reducer 141 is disposed in the inner groove wall 1211, and the other end of the reducer 141 is connected to the motor 142. By connecting the reducer 141 to the motor 142, sufficient power output from the motor can be ensured while making the winding process smoother. Specifically, the reducer 141 can effectively reduce the motor speed while amplifying the torque, ensuring that the frictional resistance of the outer sheath of the conductive wire 11 can be overcome during the winding process, improving winding efficiency, and preventing the device lifespan from being affected by motor overload.

[0055] Please refer to the following: Figures 1 to 4In some embodiments, the winding device 10 further includes a sealing housing 15, which is detachably connected to the fixed housing 12. The sealing housing 15 is provided with a plurality of engaging grooves 151 adapted to a plurality of engaging buckles 1334; the plurality of engaging grooves 151 are used to cooperate with the plurality of engaging buckles 1334 to fix the internal gear disc 13; the sealing housing 15 is also provided with a main wheel matching hole 152 that cooperates with the motor main wheel 1214; the main wheel matching hole 152 is used to fix the motor main wheel 1214 in conjunction with the main wheel hole 1326; the sealing housing 15 is also provided with a movable mating hole 153 that mates with the movable wheel 1322, the movable mating hole 153 being used to fix the movable wheel 1322 in conjunction with the movable hole 1327; the sealing housing 15 is also provided with a fixed mating hole 154 that mates with the fixed wheel 1323, the fixed mating hole 154 being used to fix the fixed wheel 1323 in conjunction with the fixed wheel hole 1328. Furthermore, a detachable snap-fit ​​structure is adopted, which allows the internal structure to remain stable while also facilitating maintenance and component replacement. The sealing housing 15 can also effectively prevent dust and foreign objects from entering the gear structure, avoiding affecting the normal operation of the clutch device, thereby improving the service life and reliability of the device.

[0056] Please refer to the following: Figure 5 In some embodiments, the end of the conductive wire 11 includes a control button 111 for controlling the retraction and release of the conductive wire 11. This allows the user to manually control the retraction and release of the conductive wire 11. Users can adjust the retraction and release according to their actual needs without relying entirely on the automatic retraction mechanism, thus improving the operability and practicality of the device.

[0057] Please refer to the following: Figure 7 In some embodiments, the winding device 10 further includes a control circuit board 16, which is disposed at the bottom of the outer groove wall 1212. The control circuit board 16 is electrically connected to the reduction motor 14, the control button 111, and the conductive wire 11. This electrical connection can also be implemented using existing structures. Furthermore, by adding the control circuit board 16, the motor and control button 111 can be electronically controlled. Specifically, this allows for more precise control of the winding and unwinding of the conductive wire 11, and further expands intelligent functions, such as detecting the tension state of the conductive wire 11 to optimize winding speed and force, thereby improving the intelligence level of the equipment.

[0058] In some embodiments, one end of the control circuit board 16 is provided with a PCB control board, which can be implemented using existing structures. Specifically, the PCB control board is provided with core pins such as VBUS (positive power supply), GND (ground), D+ / D- (data line), CC (configuration channel), and Touch (touch detection), supporting power supply, data transmission, touch control, and fast charging protocols. The other end is a rotating plate for conductive lines and buttons, with multiple conductive loops on it. Several first abutting springs can be provided on the circular partition, and these first abutting springs abut against the conductive loops on the control circuit board 16 to realize the electrical connection between the conductive lines, the control circuit board 16, and the geared motor.

The above-mentioned electrical connection method can be implemented using existing structures.

[0060] In some embodiments, the geared motor 14 can use an existing structure, and the winding device 10 can flexibly select geared motors 14 of different sizes, that is, the height dimension of the geared motor 14 can be flexibly selected, and the axial dimension of the winding device 10 can be controlled according to the actual situation.

[0061] In some embodiments, the geared motor 14 is not limited to being located in the middle of the fixed housing, but can also be located at the edge of the fixed housing, as long as it can realize the engagement of the wire pulling gear and the disengagement of the wire releasing gear.
