[0068] When charging is required, the control module 6 can control the plug drive assembly 3 to drive the plug 2 out of the housing 1 and control the cable drive assembly 5 to drive the cable 4 out of the housing 1, so that the user can plug the plug 2 into the power socket and plug the cable 4 into the charging port of the electronic product to charge the electronic product.

[0069] When charging is not required, the control module 6 can control the plug drive assembly 3 to retract the plug 2 into the housing 1 and control the cable drive assembly 5 to retract the cable 4 into the housing 1, so as to prevent the plug 2 and cable 4 from being exposed outside the housing 1, thereby making it easier for the user to store the charger of this utility model embodiment.

[0070] In some embodiments, such as Figure 1 As shown, the housing 1 is provided with a plug through hole 101 for the plug 2 to extend out of the housing 1 and retract into the housing 1; the housing 1 is provided with a cable through hole 102 for the cable 4 to extend out of the housing 1 and retract into the housing 1.

[0071] The charger of this utility model embodiment provides a plug through hole 101 on the housing 1 for the plug 2 to extend out of the housing 1 and retract into the housing 1, and a cable through hole 102 on the housing 1 for the cable 4 to extend out of the housing 1 and retract into the housing 1. This facilitates the plug driving assembly 3 to drive the plug 2 to extend out of and retract into the housing 1, and facilitates the cable driving assembly 5 to adjust the cable 4 to extend out of and retract into the housing 1.

[0072] In some embodiments, the charger of this utility model further includes an instruction module 7 that is signal-connected to the control module 6. The instruction module 7 is used to receive instructions and transmit the instructions to the control module 6 so that the control module 6 controls the plug drive component 3 and the cable drive component 5 to operate according to the instructions.

[0073] The instruction module 7 includes at least one of a voice receiving module, a tapping module, and a button module.

[0074] The voice receiving module can receive user voice commands. When the user speaks a preset command, the voice receiving module can transmit the command to the control module 6, so that the control module 6 can control the plug driving component 3 to drive the plug 2 to extend and retract the housing 1, and control the cable driving component 5 to move the cable 4 to extend and retract the housing 1.

[0075] For example, when a user says "I want to charge", the voice receiving module can transmit the command to the control module 6. The control module 6 can control the plug driving component 3 to drive the plug 2 out of the housing 1, and control the cable driving component 5 to move the cable 4 out of the housing 1, so that the user can charge.

[0076] When the user says "I don't want to charge", the voice receiving module can transmit the command to the control module 6. The control module 6 can control the plug driving component 3 to retract the plug 2 into the housing 1 and control the cable driving component 5 to retract the cable 4 into the housing 1, so as to prevent the plug 2 and cable 4 from being exposed outside the housing 1, thereby making it easier for the user to store the charger of this utility model embodiment.

[0077] The tapping module can receive user tapping commands. When the user taps the housing 1, the voice receiving module can transmit the command to the control module 6, so that the control module 6 can control the plug driving component 3 to drive the plug 2 to extend and retract the housing 1, and control the cable driving component 5 to move the cable 4 to extend and retract the housing 1.

[0078] For example, when a user taps the housing twice, the tapping module can transmit the command to the control module 6. The control module 6 can control the plug drive assembly 3 to drive the plug 2 out of the housing 1, and control the cable drive assembly 5 to move the cable 4 out of the housing 1, so that the user can charge the device.

[0079] When the user taps the housing three times, the voice receiving module can transmit the command to the control module 6. The control module 6 can control the plug driving component 3 to retract the plug 2 into the housing 1 and control the cable driving component 5 to retract the cable 4 into the housing 1, so as to prevent the plug 2 and the cable 4 from being exposed outside the housing 1, thereby making it easier for the user to store the charger of this utility model embodiment.

[0080] The button module can receive user button commands. The button module can be set on the housing 1. When the user presses a button, the button module can transmit the command to the control module 6, so that the control module 6 can control the plug drive assembly 3 to drive the plug 2 to extend and retract into the housing 1, and control the cable drive assembly 5 to move the cable 4 to extend and retract into the housing 1.

[0081] For example, the buttons include a charging button and a non-charging button. When the user presses the charging button, the button module can transmit the command to the control module 6. The control module 6 can control the plug drive assembly 3 to drive the plug 2 out of the housing 1 and control the cable drive assembly 5 to move the cable 4 out of the housing 1, so that the user can charge.

[0082] When the user presses the non-charging button, the button module can transmit the command to the control module 6. The control module 6 can control the plug drive component 3 to drive the plug 2 to retract into the housing 1 and control the cable drive component 5 to drive the cable 4 to retract into the housing 1, so as to prevent the plug 2 and cable 4 from being exposed outside the housing 1, thereby making it easier for the user to store the charger of this utility model embodiment.

[0083] In some embodiments, the charger of this utility model further includes a power supply module 8, which is disposed inside the housing 1 and is electrically connected to the plug drive assembly 3 and the cable drive assembly 5.

[0084] Furthermore, the power supply module 8 may include a battery.

[0085] By electrically connecting the battery to the plug drive assembly 3 and the cable drive assembly 5, the battery of the power supply module 8 supplies power to the plug drive assembly 3 and the cable drive assembly 5.

[0086] In some embodiments, the cable drive assembly 5 includes a winding drive motor 501, which is signal-connected to the control module 6 and electrically connected to the power supply module 8, that is, the winding drive motor 501 is electrically connected to the battery.

[0087] The reel 502 is rotatably connected to the housing 1. The cable 4 is wound on the reel 502. The drive end of the winding drive motor 501 is connected to the reel 502 to drive the reel 502 to rotate around the axis of the reel 502, thereby causing the cable 4 to extend out of the housing 1 and retract into the housing 1.

[0088] Furthermore, such as Figure 2 As shown, the outer periphery of the reel 502 is provided with a winding groove 5021, and the cable 4 is wound and disposed in the winding groove 5021.

[0089] Furthermore, such as Figure 2As shown, the winding reel 502 has a winding driven gear 504 at one end of its rotation axis. The rotation axis of the winding driven gear 504 is coaxial with the rotation axis of the winding reel 502. The driving end of the winding drive motor 501 has a winding drive gear 503. The winding drive gear 503 and the winding driven gear 504 mesh and drive each other, so that the winding drive motor 501 can drive the winding reel 502 to rotate around the rotation axis of the winding reel 502, thereby driving the lower cable 4 to extend and retract into the housing 1.

[0090] Furthermore, the diameter of the winding drive gear 503 is smaller than that of the winding driven gear 504. By setting the diameter of the winding drive gear 503 to be smaller than that of the winding driven gear 504, the rotational speed transmitted from the winding drive gear 503 to the winding driven gear 504 can be reduced, thereby making it easier to control the rotation angle of the winding drive motor 501 driving the winding reel 502.

[0091] In some embodiments, the housing 1 is provided with a guide groove 11, and in the extending direction of the guide groove 11, a guide inlet 111 and a guide outlet 112 are respectively provided at both ends of the guide groove 11.

[0092] The guide inlet 111 faces the cable reel 502 so that the cable 4 extends into the guide groove 11 through the guide inlet 111;

[0093] The guide outlet 112 is connected to the cable passage hole 102 so that the cable 4 can extend and retract into the housing 1 through the guide outlet 112 and the cable passage hole 102.

[0094] Specifically, the orientation of the guide inlet 111 can be tangent to the circumferential rotation of the reel 502, making the movement of the cable 4 between the guide groove 11 and the reel 502 smoother, thereby facilitating the cable 4 to extend and retract into the housing 1 through the guide groove 11.

[0095] Furthermore, such as Figure 3 As shown, the guide groove 11 can be defined by two spaced guide plates 12, that is, the gap between the two spaced guide plates 12 is the guide groove 11.

[0096] The charger of this utility model embodiment is provided with a guide groove 11 for the cable 4 to pass through, which makes it easy for the cable 4 to extend out of and retract into the housing 1 through the guide groove 11.

[0097] In some embodiments, the plug drive assembly 3 includes a plug drive motor 301, which is electrically connected to the battery of the power supply module 8 so that the battery can supply power to the plug drive motor 301. At the same time, the plug drive motor 301 is signal connected to the control module 6 so that the control module 6 can control the plug drive motor 301 to operate.

[0098] Plug 2 includes pins 201 and plug rotating base 202. One end of pins 201 is connected to plug rotating base 202, and plug rotating base 202 is rotatably connected to housing 1.

[0099] As shown in the figure, there are two pins 201, which are spaced apart axially on the plug rotating base 202, and one end of each pin 201 is connected and fixed to one end of the plug rotating base 202. Similarly, there are two plug through holes 101, which correspond to the two pins 201 respectively, allowing the two pins 201 to extend out of and retract into the housing 1.

[0100] The drive end of the plug drive motor 301 is connected to the plug 2 adapter to drive the plug 2 adapter to rotate around its axis, thereby causing the plug 2 to extend out of the housing 1 and retract into the housing 1. In other words, the plug drive motor 301...

[0101] Furthermore, as shown in the figure, the plug rotating seat 202 is provided with a first rotating shaft 2021 and a second rotating shaft 2022 at both ends of its rotation axis;

[0102] The housing 1 is provided with a first rotating seat 9 and a second rotating seat 10. The first rotating shaft 2021 is rotatably connected to the first rotating seat 9; the second rotating shaft 2022 is rotatably connected to the second rotating seat 10.

[0103] Furthermore, the first rotating seat 9 may be provided with a rotating hole for the first rotating shaft 2021 to be inserted, and the second rotating seat 10 may also be provided with a rotating hole for the second rotating shaft 2022 to be inserted.

[0104] Furthermore, the plug rotating base 202 is also provided with a plug driven gear 203, and the drive end of the plug drive motor 301 is provided with a plug drive gear 302. The plug drive gear 302 and the plug driven gear 203 mesh and transmit power.

[0105] Furthermore, the diameter of the plug drive gear 302 is smaller than that of the plug driven gear 203. By setting the diameter of the plug drive gear 302 to be smaller than that of the plug driven gear 203, the rotational speed transmitted from the plug drive gear 302 to the plug driven gear 203 can be reduced, thereby making it easier to control the rotation angle of the plug drive motor 301 driving the plug 2 to rotate.

[0106] Furthermore, the plug drive gear 302 and the plug driven gear 203 may also be provided with a plug transmission gear 303, the diameter of which is between the plug drive gear 302 and the plug driven gear 203, so that the plug drive gear 302 can drive the plug driven gear 203 to rotate.

[0107] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
