Description

Technical Field

[0001] This invention relates to the field of charger technology, and in particular to a charger with a hub function. Background Technology

[0002] In an era where modern electronic devices are ubiquitous, chargers play an indispensable role as key equipment for providing power to various electronic devices. A charger is a device that converts alternating current (AC) into direct current (DC) required by electronic devices. Through specific circuit design and conversion technology, it adjusts AC power sources such as mains electricity to suitable voltage and current to meet the charging requirements of different electronic devices. Mobile devices such as mobile phones, tablets, and laptops all rely on chargers to maintain normal operation and power reserves.

[0003] Different electronic devices use different charging interface standards. When users have multiple electronic devices, a charger with a single charging interface is often insufficient to meet their needs. They often need to be equipped with multiple chargers and charging cables of various specifications, which not only takes up a lot of space and is inconvenient to carry, but also increases the cost and complexity of use. When a charger connects to multiple charging cables, the charging cables are prone to getting tangled, affecting the user experience. When children are around, they may pull on the charging cables, causing damage. Young children may also put the live charging head directly into their mouths, posing a risk of electric shock. Summary of the Invention

[0004] In view of this, the present invention proposes a charger with a cable-collecting function. Based on the difference in finger length between adults and children, the trigger switch for removing the charging cable is set in a finger operation hole with a certain depth. Adults can press the trigger switch to easily and quickly remove the charging cable. Children's fingers are shorter and cannot reach the control button, thereby preventing children from unlocking the charger and avoiding the danger of children pulling out the charging cable to play with it.

[0005] The technical solution of this invention is implemented as follows:

[0006] A charger with a cable-gathering function includes a U-shaped base, a mounting cylinder, a charging module, an anti-unlocking mechanism, and a control unit. The mounting cylinder is fixedly disposed on the top of the U-shaped base and has multiple accommodating cavities spaced apart. The charging module includes a housing, a rotating shaft, a winding spool, a coil spring, and a charging cable. The housing is disposed within one of the accommodating cavities, and the rotating shaft is disposed within the housing. The winding spool is rotatably sleeved on the rotating shaft. The coil spring is sleeved on the rotating shaft, with one end fixed to the rotating shaft and the other end fixed to the winding spool. One end of the charging cable is wound around the winding spool, and the other end extends outward through the housing. The end of the charging cable has a straight rod portion. The straight rod has a connector at its end and a groove on its top surface. A T-shaped slider slides within the groove, and a helical spring is located within the groove, with one end connected to the T-shaped slider and the other end connected to the bottom of the groove. The anti-unlocking mechanism is located on one side of the mounting cylinder and includes an arc-shaped plate and a protrusion. The protrusion is located on the side of the arc-shaped plate and has parallel through holes and finger operation holes at its top and bottom, respectively. The bottom inner wall of the finger operation hole communicates with the through hole through a connecting hole. The straight rod can slide to the outside through the through hole. The control unit is located inside the U-shaped base and is electrically connected to the charging module.

[0007] Preferably, the anti-unlocking mechanism further includes a fan-shaped plate and a second rotating shaft. The two ends of the arc-shaped plate are respectively connected to the second rotating shaft through the fan-shaped plate, and the second rotating shaft is rotatably disposed on both sides of the U-shaped base.

[0008] Preferably, it also includes a drive mechanism, which includes an electric push rod, a U-shaped frame, a drive gear, a rack, and a trigger switch. The arc-shaped plate has a cavity that communicates with the bottom of the through hole. The electric push rod is located at the top of the cavity, and its telescopic end is connected to the U-shaped frame. The electric gear is rotatably located in the middle of the U-shaped frame. The rack is located at the top of the charging cable, and the trigger switch is located at the bottom of the groove.

[0009] The driving mechanism also includes an electromagnet, which is located at the bottom of the groove.

[0010] Preferably, the receiving cavity has an opening on one side, and the charging module can be installed into the receiving cavity from the opening. The housing has a male connector on its side, and the receiving cavity has a female connector on its inner wall. The male connector is inserted into the female connector.

[0011] Preferably, the straight rod portion has multiple annular grooves near its end.

[0012] Preferably, it further includes a fixing mechanism, which includes a connecting plate, a support plate, a lead screw, a moving block, a pawl, a knob, and a fastening nut.

[0026] To better understand the technical content of this invention, a specific embodiment is provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0027] Example 1:

[0028] See Figures 1 to 7This invention provides a charger with a cable-gathering function. The charger further includes a U-shaped base 1, a mounting cylinder 2, a charging module, and a control unit 20. The mounting cylinder 2 is fixedly disposed on the top of the U-shaped base 1 and has multiple accommodating cavities 3 spaced apart. The charging module is disposed within the accommodating cavities 3. The charging module includes a housing 12, a rotating shaft 13, a winding spool 23, a coil spring 37, and a charging cable 24. The housing 12 is disposed within the accommodating cavities 3. The rotating shaft 13 is rotatably disposed within the housing 12. The winding spool 23 is rotatably sleeved on the rotating shaft 13. The coil spring 37 is sleeved on the rotating shaft 13 and located within a groove 28 on the side of the winding spool 23, with one end fixed to the rotating shaft 13 and the other end fixed to the winding spool 23. One end of the charging cable 24 is wound around the winding spool, and the other end passes through the housing 1. 2. A through hole 8 is provided on the side. The charging cable 24 has a straight rod 25 at its end. The straight rod 25 has a connector 26 at its end. The top surface of the straight rod end has a groove 28. A limiting block is slidably provided in the groove 28. A helical spring 29 is provided in the groove 28. The limiting mechanism is provided on one side of the mounting cylinder 2. The limiting mechanism includes an arc plate 5 and a protrusion 6. The protrusion 6 is provided on the side of the arc plate 5. The protrusion 6 has a through hole 8 and a finger operation hole 7 that are parallel to each other at its top and bottom. The bottom inner wall of the finger operation hole 7 is connected to the through hole 8 through a connecting hole 9. The straight rod 25 is slidably provided in the through hole 8. The straight rod 25 can extend to the outside through the through hole 8. The control unit 20 is provided in the inner cavity of the U-shaped base 1 and is electrically connected to the charging module and the drive mechanism.

[0029] When charging the device, first insert your finger into the finger operation hole 7 and press the T-shaped slider 27 with your fingertip. The T-shaped slider 27 descends into the groove 28. At the same time, pull the T-shaped slider 27 with your fingertip. The movement of the T-shaped slider 27 causes the straight rod 25 to slide outward through the through hole 8. The charging cable 24 moves outward along the through hole 8 for a predetermined length. Then, pinch the exposed straight rod 25 and pull the charging cable 24 out of the housing 12. Then, connect the plug 26 to the corresponding charging port of the device. As the charging cable 24 is pulled out of the housing 12, the charging cable 24 drives the winding shaft 23 to rotate and release the charging cable 24. At the same time, the rotation of the winding shaft 23 causes the coil spring 37 to continuously coil, converting the tension into elastic potential energy. After the charging operation is completed, connect the plug... The head 26 is separated from the charging port of the electrical device. Under the action of the coil spring 37, the charging cable 24 is driven to rotate the winding spool 23 to store the charging cable 24 and wind it on the winding spool 23. With the groove 28 of the straight rod 25 facing upward, the T-shaped slider 27 is pressed down, and the straight rod 25 is retracted into the through hole 8. As the straight rod 25 slides inward, when the T-shaped slider 27 is aligned with the connecting through hole 9, the T-shaped slider 27 moves into the connecting through hole 9 under the push of the coil spring 29. The side of the T-shaped slider 27 abuts against the inner wall of the connecting through hole 9, limiting the charging cable 24, thereby completing the reset of the charging cable 24. At this time, the connector 26 at the end is located in the through hole 8. The diameter of the through hole 8 is small, so children cannot pull out the charging cable 24 to play through the through hole 8.

[0030] Working principle of the anti-unlocking mechanism: The average length of a normal adult's thumb is about 57mm, the average length of the index finger is about 72mm, and the average length of the middle finger is about 78mm. The size of the finger operation hole 7 is adapted to the adult's finger. Children's fingers are shorter, generally about 20mm. The connecting through hole 9 is located on the inner side of the finger operation hole 7 at a predetermined depth. After an adult inserts their finger into the finger operation hole 7, they can press and pull the T-shaped slider 27 with their fingertip. The T-shaped slider 27 descends into the groove 28, releasing the restriction and making it easy to quickly remove the charging cable 24. Children's fingers are shorter and are restricted by the finger operation hole 7, so they cannot access the T-shaped slider 27 and cannot unlock the charging cable 24, thus preventing them from pulling out the charging cable 24 to play with it and causing danger.

[0031] Preferably, the anti-unlocking mechanism further includes a fan-shaped plate 4 and a second rotating shaft 14. The two ends of the arc-shaped plate 5 are respectively connected to the second rotating shaft 14 through the fan-shaped plate 4. The second rotating shaft 14 is rotatably disposed on both sides of the U-shaped base 1.

[0032] By rotating the fan-shaped plate 4, the direction of the finger operation hole 7 can be adjusted, which makes it easier to insert the finger into the finger operation hole 7 in a comfortable position when unlocking, so as to smoothly unlock the charging cable 24.

[0033] Example 2:

[0034] The difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 also includes a drive mechanism, which includes an electric push rod 31, a U-shaped frame 32, a drive gear, a rack 34, and a trigger switch 39. The arc-shaped plate 5 has a cavity 30, which is connected to the bottom of the through hole 8. The electric push rod 31 is located at the top of the cavity 30, and its telescopic end is connected to the U-shaped frame 32. The electric gear 33 is rotatably located in the middle of the U-shaped frame 32. The rack 34 is located at the top of the charging cable 24, and the trigger switch 39 is located at the bottom of the groove 28.

[0035] In this second embodiment, the user inserts their finger into the finger operation hole 7 and presses down on the T-shaped slider 27 with their fingertip. The T-shaped slider 27 moves down away from the connecting through hole 9 and enters the groove 28. The bottom surface of the T-shaped slider 27 presses down to trigger the switch 39, activating the drive mechanism and activating the electric push rod 31. Its telescopic end extends and drives the U-shaped frame 32 to descend. The descent of the U-shaped frame 32 drives the electric gear 33 to descend and engage with the rack 34. Then, the electric gear 33 is activated, and its rotation drives the rack 34 to move, driving the end of the straight rod 25 to move a predetermined length outside the through hole 8. The charging cable 24 can be pulled out by pinching the straight rod 25 with the hand. Unlocking the charging cable 24 only requires pressing the T-shaped slider 27 with the fingertip, simplifying the unlocking action and making it more convenient to use.

[0036] Preferably, the driving mechanism further includes an electromagnet 38, which is disposed at the bottom of the groove 28.

[0037] When the bottom surface of the T-shaped slider 27 is pressed down to trigger the switch 39, the electromagnet 38 is activated, generating electromagnetic force to attract the T-shaped slider 27 for a predetermined time. This facilitates the locking between the T-shaped slider 27 and the connecting through hole 9 during operation. During the process of the charging cable 24 sliding out of the through hole 8, there is no contact pressure between the T-shaped slider 27 and the through hole 8, reducing friction and facilitating the pulling out of the charging cable 24.

[0038] Preferably, the receiving cavity 3 has an opening on one side, and the charging module can be installed into the receiving cavity 3 from the opening. The housing 12 has a male connector 11 on its side, and the receiving cavity 3 has a female connector 10 on its inner wall. The male connector 11 is inserted into the female connector 10.

[0039] The charging modules are detachably installed in the receiving cavity 3. When one of the charging modules is damaged, first insert your finger into the finger operation hole 7 and press the T-shaped slider 27 with your fingertip. The T-shaped slider 27 descends into the groove 28. Under the elastic force of the coil spring 37, the charging cable 24 retracts and releases the limit. Rotate the arc plate 5 around its pivot 14 to remove the charging cable 24 from the through hole 8. Then rotate the arc plate 5 to the other side of the opening of the receiving cavity 3. This allows for convenient replacement of the charging modules individually.

[0040] Preferably, the straight rod portion 25 is provided with a plurality of annular grooves 40 near its end.

[0041] When an adult inserts their finger into the finger operation hole 7, they can press and pull the T-shaped slider 27 with their fingertip. The T-shaped slider 27 descends into the groove 28, releasing the limit. The movement of the T-shaped slider 27 causes the straight rod 25 to slide out of the through hole 8. The annular groove 40 plays an anti-slip role, which is conducive to pulling out the charging cable 24.

[0042] Preferably, it also includes a fixing mechanism, which includes a connecting plate 22, a support plate 16, a lead screw 19, a moving block 21, a pawl 15, a knob 18, and a fastening nut 17. The support plate 16 is connected to the side of the U-shaped base 1 through the connecting plate 22. The support plate 16 is provided with an open slide groove, in which the lead screw 19 is rotatably mounted. One end of the lead screw 19 is rotatably mounted on the support plate 16, and the other end passes through the support plate 16 and is connected to the knob 18. The fastening nut 17 is threadedly connected to the lead screw 19 and is located between the knob 18 and the support plate 16. The moving block 21 is disposed opposite to both ends of the lead screw 19. The moving block 21 is provided with pawls 15 on its side. The two ends of the lead screw 19 are provided with threads in opposite directions.

[0043] The fixing mechanism allows the charger to be installed on top of the car seat. First, loosen the fastening nut 17 by turning it. Then, turn the knob 18. The rotation of the knob 18 drives the lead screw 19 to rotate. The rotation of the lead screw 19 simultaneously drives the moving block 21 to move in opposite directions. The movement of the moving block 21 drives the claws 15 to move. After the distance between the two claws 15 decreases, the two claws 15 are inserted between the two sliding rods of the headrest on the top of the seat. Then, turn the knob 18 to rotate the lead screw 19 in the opposite direction. The rotation of the lead screw 19 simultaneously drives the moving block 21 to move in the opposite direction. The distance between the claws 15 increases, and they are engaged between the two sliding rods of the headrest on the top of the seat. Finally, turn the fastening nut 17 to fasten the lead screw 19 to the support plate 16, thus completing the fixing of the charger.

[0044] Preferably, the protrusion 6 is made of a transparent material.

[0045] When the charging cable 24 is retracted into the through hole 8 under the action of the coil spring 37, the corresponding interface can be identified by observing the charging plug 36 at the end of the charging cable 24, which is beneficial for quickly pulling out the charging cable 24.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
