[0022] As shown in FIGS. 1 to 6, the present invention provides a smart winding type charger including a charger body 1. Inside the charger body 1, a winding case 2, a charging cable 4, a main control board assembly, a switch control element, a winding drive assembly, and a folding pin 15 are provided. The winding drive assembly includes a winding drive motor 7, an interlocking member, and an advancement assist drive assembly. The moving end of the winding drive motor 7 is interlocked with the advancement assist drive assembly by the interlocking member, and a winding connection portion 71 is provided at the moving end of the winding drive motor 7. Both the winding connection portion 71 and the charging cable 4 are provided on the winding case 2, and one end of the charging cable 4 is connected to the winding connection portion 71. The winding case 2 is provided with an entrance / exit 20 that cooperates with the charging cable 4. The charger body 1 is provided with a cable entrance / exit 10 that cooperates with the entrance / exit 20. The winding drive motor 7 can rotationally drive the winding connection portion 71 to wind the charging cable 4 around the winding connection portion 71 and store it in the winding case 2. The advancement assist drive assembly is provided between the entrance / exit 20 and the cable entrance / exit 10. The advancement assist drive assembly can perform winding or unwinding of the wire by pushing and pulling the charging cable 4.

[0023] Due to the arrangement of the winding case 2, the charging cable 4 can be stored inside the product to protect the wire. By the cooperation of the winding drive motor 7 and the advancement assist drive assembly, the storage or unwinding operation of the charging cable 4 can be efficiently automated, eliminating the need to manually store the wire, improving user convenience, ensuring the accuracy of wire storage, avoiding wire knots, meeting the user's usage needs, and being beneficial to improving the competitiveness of the product.

[0024] The winding connection section 71 is a winding frame. A winding connection cylinder 710 is provided at the lower end of the winding frame. A winding column 711 is provided on the winding connection cylinder 710. A drive mounting hole 7110 is provided on the lower end surface of the winding column 711, which cooperates with the moving end of the winding drive motor 7. The winding frame is provided with a wiring port 712 that cooperates with the winding connection cylinder 710. A winding notch 7100 that cooperates with the charging cable 4 is provided on the side of the winding connection cylinder 710. One end of the charging cable passes through the winding notch 7100 and is provided around the winding column 711, and the charging cable 4 is electrically connected to the main control board assembly by passing through the wiring port 712.

[0025] Since one end of the charging cable 4 passes through the winding notch 7100 and is provided around the winding column 711, one end of the charging cable 4 is always provided in the winding connection cylinder 710, and any detachment of the charging cable 4 can be avoided in relation to the use of the product.

[0026] During use, the user activates the winding drive motor 7 using a switch control element to perform winding or unwinding operations. When it is necessary to store the wire, the user controls the moving end of the winding drive motor 7 using a switch control element to rotate the winding frame forward, the unwinding assist drive assembly pulls the charging cable 4 into the entrance / exit 20, the charging cable 4 is stored around the outer circumference of the winding connection cylinder 710, and the storage operation is completed after the moving end of the winding drive motor 7 has rotated a predetermined number of times.

[0027] When it is necessary to extend the charging cable 4, the moving end of the winding drive motor 7 reverses the winding frame, the extension assist drive assembly extends the charging cable 4 from the cable entrance / exit 10 for use by the user, and the extending operation is completed after the moving end of the winding drive motor 7 has rotated a predetermined number of times.

[0028] The winding case 2 includes a winding case upper cover 21 and a winding case lower cover 22.

[0029] The main control board assembly includes a relay circuit board 51 and a main control circuit board 52. The upper end surface of the winding frame is provided with a relay mounting groove 713 that cooperates with the relay circuit board 51. One end of the charging cable is electrically connected to the relay circuit board 51. The inner wall of the winding case 2 is provided with a main control mounting portion that cooperates with the main control circuit board 52. A connector is provided on the upper end surface of the relay circuit board 51, and a plurality of connecting spring pieces 510 are provided on the connector. The lower end surface of the main control circuit board 52 is provided with a conductive layer that cooperates with the connecting spring pieces 510. The connecting spring pieces 510 can contact the conductive layer by elastic restoring force.

[0030] With this arrangement, the connecting spring piece 510 is always electrically connected to the conductive layer of the main control circuit board 52 as the relay circuit board 51 rotates along the winding frame.

[0031] The winding case 2 is provided with a mounting portion 3 that cooperates with the interlocking member. The interlocking member includes a driving gear 81 and a driven gear group 82. The driving gear 81 is fixed coaxially to the moving end of the winding drive motor 7. The driving gear 81 meshes with one end of the driven gear group 82. The advance auxiliary drive assembly includes an interlocking gear 91 and at least one auxiliary rotating shaft 92. The interlocking gear 91 is fixed to the auxiliary rotating shaft 92. The interlocking gear 91 meshes with the other end of the driven gear group 82. Both the auxiliary rotating shaft 92 and the driven gear group 82 are rotatably mounted on the mounting portion 3.

[0032] By rotating the main drive gear 81 with the winding drive motor 7, the driven gear group 82 is rotated, thereby enabling the winding drive motor 7 and the extension assist drive assembly to work together.

[0033] There is one auxiliary rotating shaft 92. A support bump 23 is provided on the outside of the entrance / exit 20, which engages with the auxiliary rotating shaft 92 to clamp the charging cable 4. The winding case 2 is further provided with an upper adjustment seat 24. The mounting portion 3 is a mounting plate provided below the winding case 2. The mounting plate is provided with a rotating hole that cooperates with the moving end of the winding drive motor 7, and the mounting plate does not rotate in accordance with the moving end of the winding drive motor 7. The mounting plate is provided between the lower end surface of the winding case 2 and the drive gear 81. The drive gear 81 clamps the mounting plate and fixes it to the lower end surface of the winding case 2. The mounting plate is rotatably pivotable relative to the winding case 2. The upper adjustment seat 24 is provided with an adjustment slot 241 that cooperates with the auxiliary rotating shaft 92. The upper end of the auxiliary rotating shaft 92 is provided in the adjustment slot 241. The upper adjustment seat 24 and the mounting plate are capable of supporting both the upper and lower ends of the auxiliary rotating shaft 92, respectively. The tightness with which the charging cable 4 is clamped can be adjusted by changing the relative position of the auxiliary rotating shaft 92 in the adjustment slot 241.

[0034] The auxiliary rotating shaft 92 presses the charging cable 4 in the direction of the support bump 23, thereby fixing the charging cable 4 between the auxiliary rotating shaft 92 and the support bump 23. The auxiliary rotating shaft 92 rotates forward or backward to stably drive the charging cable 4 to retract or extend the wire.

[0035] The upper adjustment seat 24 and the mounting plate support both the upper and lower ends of the auxiliary rotating shaft 92, thereby improving the stability of the rotation of the auxiliary rotating shaft 92, as well as improving the stability of the clamping of the charging cable 4 by the auxiliary rotating shaft 92 and the support bump 23.

[0036] Simultaneously, by oscillating the mounting plate and changing the relative position of the auxiliary rotating shaft 92 in the adjustment slot 241, the auxiliary rotating shaft 92 can be moved closer to or further away from the support projection 23, thereby changing the tightness with which it grips the charging cable 4 and allowing it to be adapted to different wire materials.

[0037] Clearly, the arrangement with one auxiliary rotating shaft 92, in which the auxiliary rotating shaft 92 cooperates with the support bump 23 to grip both ends of the charging cable 4, thereby achieving the effect of pushing and pulling the charging cable 4 to store or unload the wire, can be replaced by other configurations. For example, if there are two auxiliary rotating shafts 92, with each of the two auxiliary rotating shafts 92 provided on either side of the charging cable 4, and the interlocking gears 91 under the two auxiliary rotating shafts 92 cooperate with the driven gear group 82, the driven gear group 82 can simultaneously rotate the two auxiliary rotating shafts 92, and by controlling the rotation directions of the two auxiliary rotating shafts 92 in opposite directions, the effect of pushing and pulling the charging cable 4 to store or unload the wire can be achieved in a similar manner.

[0038] The charger body 1 is provided with a connector groove 11 on the side of the cable inlet / outlet 10 that cooperates with the connector of the charging cable 4. The connector groove 11 can secure the connector of the charging cable 4.

[0039] The placement of the connector groove 11 allows the connector of the charging cable 4 to be stored and protected. Before extending and using the cable, the user must manually remove the connector of the charging cable 4 from the connector groove 11, and after storing the wire, manually reattach the connector of the charging cable 4 to the connector groove 11 to improve the stability of the wire storage.

[0040] A silicone sealing sleeve 12 is provided at the cable entry / exit point 10. The silicone sealing sleeve 12 has a sealing hole that cooperates with the charging cable 4, and the charging cable 4 is placed in the sealing hole.

[0041] The placement of the silicone sealing sleeve 12 effectively improves the airtightness of the product during use, preventing dust or foreign matter from entering the product and affecting its lifespan.

[0042] The switch control element includes a touch switch control element 61 and a sound sensor 62. An electrical connection window 210 is provided on the upper end surface of the winding case 2. The touch switch control element 61 and the sound sensor 62 can be electrically connected to the main control circuit board 52 through the electrical connection window 210. The upper end surface of the charger body 1 is provided with a touch mounting hole 100 and a sound collection hole 101, which cooperate with the touch switch control element 61 and the sound sensor 62, respectively.

[0043] The arrangement of the touch switch control element 61 and the voice sensor 62 allows the user to control the retraction or extension of the charging cable via touch or voice commands, thereby improving the product user experience.

[0044] The charger body 1 further includes a motor power supply board 17 and an expansion wiring board 13. A relay window 200 that cooperates with the main control circuit board 52 is provided on the side of the winding case 2. The main control circuit board 52 is provided with connection terminals 520. The connection terminals 520 are provided protruding from the relay window 200. The motor power supply board 17 is provided with a connecting flat cable that cooperates with the connection terminals 520. The winding drive motor 7 and the expansion wiring board 13 are electrically connected to the motor power supply board 17, respectively. The expansion wiring board 13 is provided with an expansion wiring interface 131. The charger body 1 is provided with an expansion receptacle 14 that cooperates with the expansion wiring interface 131.

[0045] The placement of the extension wiring interface 131 allows for the use of another charging cable 4 to access the product.

[0046] The lower end surface of the charger body 1 is provided with a folding groove 16 that cooperates with a folding pin 15. The folding pin 15 is hinge-connected to the folding groove 16.

[0047] The folding pin 15 and the folding groove 16 work together to allow the product to be folded and stored when not in use.

[0048] As can be seen from the above, the beneficial effects of this invention are as follows: By adopting such a structure, the problem of poor user experience in the wire storage structure of conventional chargers can be effectively solved. The arrangement of the winding case 2 allows the charging cable to be stored inside the product and the wire to be protected. The cooperation between the winding drive motor 7 and the extension assist drive assembly allows the storage or unwinding operation of the charging cable 4 to be efficiently automated, eliminating the need to store the wire manually, improving usability, ensuring accuracy in wire storage, avoiding knots in the wire, meeting user needs, and contributing to improved product competitiveness.
