[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-3 and Figure 5This utility model provides a technical solution: a charging head protection component, including a circular shell 2 for storage, a charging head body 3 for mounting components at the front of the circular shell 2, a protection mechanism 5 for protecting the plug pins inside the charging head body 3, and a power transmission mechanism 4 for protecting the wires inside the circular shell 2.

[0029] The power transmission mechanism 4 includes a shaft 401 for transmission that is connected through a bearing on the inner wall of the circular shell 2. A conductive slip ring 402 for conducting electricity is connected to the outer side of the shaft 401. The conductive slip ring 402 is connected to one side of the circular shell 2. A partition plate 403 for separation is connected to the outer side of the shaft 401 away from the conductive slip ring 402. A coil spring 404 for resetting is abutted on one side of the partition plate 403. One end of the coil spring 404 is connected to the outer side of the shaft 401 and the other end of the coil spring 404 is connected to the inner wall of the circular shell 2.

[0030] The charging head protection assembly and portable power device have a circular shell 2 connected to one side of the portable power supply 1 by bolts. One side of the conductive slip ring 402 is connected to the circular shell 2. At the same time, the conductive slip ring 402 is installed on the inner wall of the portable power supply 1. The end of the charging cable 405 is connected to the cable on the inner cylinder of the shaft 401. The cable on the outer cylinder of the conductive slip ring 402 is connected to the battery protection board inside the portable power supply 1 for rotational power supply. The cable is wound in the opposite direction.

[0031] When the shaft 401 rotates, it twists the partition 403. After the shaft 401 is released, the partition 403 will drive the shaft 401 to rotate back to its original position, thereby rewinding the charging cable 405.

[0032] exist Figures 3-5 In the middle, the side of the partition 403 away from the coil spring 404 abuts against the charging cable 405 for power transmission. The charging cable 405 is wound around the outside of the shaft 401. One end of the charging cable 405 is connected through the shaft 401, and the other end of the charging cable 405 is connected to the charging head body 3 through the through hole in the round shell 2.

[0033] The charging head protective assembly and portable power device have a charging cable 405 connected to the insert body 502 inside the charging head body 3. Pulling the charging head body 3 externally causes the charging cable 405 to unwind, and the charging cable 405 drives the shaft 401 to rotate, thus twisting the coil spring 404.

[0034] exist Figure 4 and Figure 5In the middle, one side of the charging cable 405 abuts against a baffle 406 for shielding. The outer side of the shaft 401 near the baffle 406 is connected to a ratchet 407 for limiting. The outer side of the ratchet 407 is engaged with a pawl 408 for limiting. The pawl 408 is rotatably connected to one side of the inner wall of the circular shell 2 via a pivot. The pawl 408 passes through and slides in the opening on the inner wall of the circular shell 2. A tension spring 409 for resetting is connected below the pawl 408. The other end of the tension spring 409 is connected to one side of the inner wall of the circular shell 2.

[0035] When the external charging head body 3 is pulled to rotate the shaft 401, the ratchet 407 on the shaft 401 rotates simultaneously with the shaft 401. The tension spring 409 pulls the pawl 408, which remains engaged with the ratchet 407. When the charging cable 405 is released, the coil spring 404 drives the shaft 401 to rotate in the opposite direction to reset. At this time, the ratchet 407 is locked by the pawl 408, preventing the shaft 401 from rotating and limiting the charging cable 405. When the pawl 408 is rotated, it moves away from the ratchet 407 and no longer limits the shaft 401. The coil spring 404 drives the shaft 401 to rotate and reset, winding the charging cable 405 around the shaft 401. By retracting the charging cable 405 into the circular shell 2, the charging cable 405 is protected and prevented from tangling.

[0036] exist Figure 6 In the middle, the protection mechanism 5 includes a conductive insert body 502 connected to the inner wall of the charging head body 3, a protective shell 501 slidably connected to the insert body 502, a T-shaped groove 503 for limiting the position is opened in the protective shell 501, a T-shaped rod 504 for limiting the position is slidably connected to the inner wall of the T-shaped groove 503, the T-shaped rod 504 is connected to the inner wall of the charging head body 3, and a spring a505 for resetting is sleeved on the outer side of the T-shaped rod 504, the spring a505 abutting between the inner wall of the charging head body 3 and the protective shell 501.

[0037] The charging head protective assembly and portable power device are designed to retract the protective shell 501 into the charging head body 3 by pressing it, thus exposing the insert body 502. The insert body 502 is then inserted into the socket for charging. When the protective shell 501 is pulled out of the socket, the spring a505 pushes the protective shell 501 back to its original position, blocking the insert body 502 and preventing it from being squeezed, bent, or deformed, thus preventing it from being inserted into the socket.

[0038] exist Figure 7In the middle, the protective shell 501 has slots 513 for limiting on both sides. The inner wall of the charging head body 3 near the slots 513 has slots 506 on both sides. A spring b507 for resetting is connected to the inner wall of the slot 506. The other end of the spring b507 is connected to a helical tooth plate 508 for limiting. The back of the helical tooth plate 508 is meshed with a long gear 509 for driving the helical tooth plate 508 to move.

[0039] The charging head protection assembly and portable power device have a limiting groove for limiting the position inside the helical tooth plate 508, and a limiting rod is slidably connected inside the limiting groove. The limiting rod is connected to the inner wall of the empty groove 506.

[0040] When the protective shell 501 is pressed, the protective shell 501 presses the inclined surface of the inclined tooth plate 508 and pushes the inclined tooth plate 508 into the empty slot 506. When the protective shell 501 is retracted into the charging head body 3, the slot 513 is aligned with the empty slot 506, and the spring b507 pushes the inclined tooth plate 508 into the slot 513, thereby preventing the protective shell 501 from resetting.

[0041] When the long gear 509 is rotated, the helical gear plate 508 is pulled out from the slot 513 and retracted into the empty slot 506. The helical gear plate 508 no longer limits the protective shell 501, and the spring a505 pushes the protective shell 501 to reset.

[0042] exist Figure 8 and Figure 9 In the middle, an arc-shaped groove 510 is provided on the inner wall of the charging head body 3 near the empty groove 506. An arc-shaped toothed plate 511 for driving the short gear 512 to rotate is rotatably connected to the inner wall of the arc-shaped groove 510 via a rotating shaft. A short gear 512 for driving the long gear 509 to rotate is meshed on the inner wall of the arc-shaped toothed plate 511. The short gear 512 passes through and is rotatably connected to the inner wall between the empty groove 506 and the arc-shaped groove 510, and the short gear 512 is connected below the long gear 509.

[0043] When the charging head protective assembly and portable power device are pressed, the arc-shaped toothed plate 511 is rotated, and the arc-shaped toothed plate 511 drives the short gear 512 and the long gear 509 to rotate together, thereby retracting the helical toothed plate 508 into the empty slot 506.

[0044] Arc-shaped grooves 510 and short gears 512 are provided above and below the long gear 509. A set of arc-shaped tooth plates 511 simultaneously drive the two sets of short gears 512 to rotate.

[0045] A portable power supply device includes: a portable power supply 1, on which a charging head protection component as described above is installed.

[0046] In summary: When using this charging head protection component and portable power device, firstly, insert the plug of the power device into the socket on one side of the portable power supply 1 to use the power. When the portable power supply 1 has low or no power, pull out the charging head body 3 to pull out the charging cable 405, then press the protective shell 501 to retract it into the charging head body 3, expose the insert body 502, and plug it into the power socket to charge the portable power supply 1. After it is fully charged, press the arc-shaped toothed plate 511 to pull out the charging head body 3, and then move the pawl 408 to retract the charging cable 405 into the round shell 2. The contents not described in detail in this description belong to the prior art known to those skilled in the art.
