It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] Please refer to FIG. 1 to FIG. 4, the application provides a winding mechanism 100. The winding mechanism 100 can be used to wind the wire body 200, realize the automatic winding of the wire body 200, and effectively improve the winding efficiency and convenience of the wire body 200. The wire body 200 can be a data line, a cable, a flexible pipe, a wool yarn, a hemp rope, etc., but is not limited thereto. The embodiments of the application take the wire body 200 as a data line as an example for description.

[0033] The winding mechanism 100 includes a winding assembly 101 and a detection assembly 102. The winding assembly 101 is used to carry and wind the wire body 200. The detection assembly 102 is connected with the winding assembly 101, and is used to monitor the working state of the wire body 200, and control the winding assembly 101 to wind the wire body 200 when the working state meets the winding condition. The working state includes an electrical working state and a mechanical working state. The electrical working state includes a charging state and a non-charging state. The mechanical working state includes a wire-out state and a non-wire-out state. If the detection assembly 102 detects that the electrical working state is the non-charging state and the mechanical working state is the wire-out state, it is determined that the working state meets the winding condition.

[0034] The detection assembly 102 can acquire the working state of the wire body 200 received by the take-up assembly 101, and determine whether the working state meets the take-up condition. The detection assembly 102 can also control the take-up assembly 101 to wind the wire body 200 when the working state of the wire body 200 meets the take-up condition. The working state of the wire body 200 meeting the take-up condition includes that the electrical working state is the non-charging state, and the mechanical working state is the wire-out state. It can be understood that if the wire body 200 is in the non-charging state and the non-wire-out state, it means that the working state of the wire body 200 does not meet the take-up condition, and the detection assembly 102 will not control the take-up assembly 101 to perform the take-up action; if the wire body 200 is in the charging state and the wire-out state, it means that the working state of the wire body 200 does not meet the take-up condition, and the detection assembly 102 will not control the take-up assembly 101 to perform the take-up action; if the wire body 200 is in the non-charging state and the wire-out state, it means that the working state of the wire body 200 meets the take-up condition, and the detection assembly 102 controls the take-up assembly 101 to perform the take-up action.

[0035] The detection assembly 102 can acquire the electrical working state and the mechanical working state of the wire body 200, and detect whether the electrical working state is the non-charging state and whether the mechanical working state is the wire-out state. If the detection assembly 102 detects that the electrical working state is the non-charging state and the mechanical working state is the wire-out state, it is determined that the working state meets the take-up condition. Through such a structure, the detection assembly 102 automatically controls the take-up assembly 101 to automatically wind the wire body 200 when it is determined that the working state of the wire body 200 meets the take-up condition, that is, the detection assembly 102 controls the take-up assembly 101 to wind the wire body 200 directly through the working state of the wire body 200, so that the automatic winding of the wire body 200 can be realized, and the winding efficiency of the wire body 200 is improved.

[0036] In some embodiments, the detection assembly 102 includes a timing piece 31. The timing piece 31 is used to start timing when the detection assembly 102 determines that the electrical working state is the non-charging state and the mechanical working state is the wire-out state. If the wire body 200 remains in the non-charging state and the wire-out state for a time greater than a first preset time, it is determined that the working state meets the take-up condition.

[0037] The detection assembly 102 can control the timing element 31 to accumulate the time of the wire body 200 in the non-charging state and the unwinding state when the mechanical working state of the wire body 200 enters the unwinding state from the non-unwinding state. If the time accumulated by the timing element 31 is less than the first preset time length, the wire body 200 enters the charging state, the detection assembly 102 determines that the working state of the wire body 200 does not meet the winding condition, and controls the timing element 31 to clear the time. If the time accumulated by the timing element 31 is greater than the first preset time length, the wire body 200 still does not enter the charging state, the detection assembly 102 determines that the working state of the wire body 200 meets the winding condition, and controls the winding assembly 101 to perform the winding action and controls the timing element 31 to clear the time.

[0038] The detection assembly 102 can also control the timing element 31 to accumulate the time of the wire body 200 in the non-charging state and the unwinding state when the mechanical working state of the wire body 200 is in the unwinding state and the electrical working state enters the non-working state. If the time accumulated by the timing element 31 is less than the first preset time length, the wire body 200 enters the charging state again from the non-charging state, the detection assembly 102 determines that the working state of the wire body 200 does not meet the winding condition, and controls the timing element 31 to clear the time. If the time accumulated by the timing element 31 is greater than the first preset time length, the wire body 200 still does not enter the charging state, the detection assembly 102 determines that the working state of the wire body 200 meets the winding condition, and controls the winding assembly 101 to perform the winding action and controls the timing element 31 to clear the time.

[0039] By accumulating the time of the wire body 200 in the unwinding state by the timing element 31, and the detection assembly 102 determines that the working state of the wire body 200 meets the winding condition only when the time of the wire body 200 in the non-charging state and the unwinding state is greater than the first preset time length, on the one hand, the wire body 200 can be kept in the non-charging state and the unwinding state within the first preset time length, reducing the situation that the detection assembly 102 controls the winding assembly 101 to wind the wire body 200 before the charging operation, on the other hand, the detection assembly 102 can automatically control the winding assembly 101 to wind the wire body 200 when the time of the wire body 200 in the non-charging state and the unwinding state is greater than the first preset time length, preventing the placement position of the winding mechanism 100 from being messy due to the wire body 200 being in the non-charging state and the unwinding state for a long time, and improving the user experience.

[0040] The timing element 31 can be a stopwatch, a timer, etc., but is not limited thereto.

[0041] The first preset time length of the wire body 200 remaining in the non-charging state and the out-of-line state can be 0.5-10 minutes, for example, the first preset time length of the wire body 200 remaining in the non-charging state and the out-of-line state can be 0.5 minutes, 0.88 minutes, 1 minute, 1.35 minutes, 1.66 minutes, 1.85 minutes, 2 minutes, 2.5 minutes, 2.93 minutes, 3.3 minutes, 3.5 minutes, 3.76 minutes, 4 minutes, 4.5 minutes, 4.88 minutes, 5 minutes, 5.2 minutes, 5.5 minutes, 5.8 minutes, 6 minutes, 6.35 minutes, 6.6 minutes, 7 minutes, 7.65 minutes, 8 minutes, 8.5 minutes, 9 minutes, 9.5 minutes, 10 minutes, etc., but not limited thereto.

[0042] In some embodiments, the outer end of the wire body 200 is provided with a magnetic piece 201. The inner end of the wire body 200 is connected with the take-up assembly 101. The detection assembly 102 further comprises a magnetic induction piece 32 and a main controller 40. The magnetic induction piece 32 is arranged on the take-up assembly 101, and is used to sense the magnetic piece 201 and generate a magnetic signal when the outer end of the wire body 200 is wound on the take-up assembly 101. The main controller 40 is connected with the magnetic induction piece 32, and determines the out-of-line state based on the magnetic signal.

[0043] The outer end of the wire body 200 refers to the end connected with the external device. By arranging the magnetic induction piece 32 on the take-up assembly 101, when the wire body 200 is pulled out of the take-up assembly 101, the magnetic induction piece 32 cannot sense the magnetic piece 201, and when the wire body 200 is wound on the take-up assembly 101, the magnetic induction piece 32 can sense the magnetic piece 201 and generate a magnetic signal. The main controller 40 is connected with the magnetic induction piece 32, and is used to receive the magnetic signal generated by the magnetic induction piece 32. If the main controller 40 can receive the magnetic signal, it is determined that the wire body 200 is in the out-of-line state, and if the main controller 40 cannot receive the magnetic signal, it is determined that the wire body 200 is in the non-out-of-line state.

[0044] The magnetic induction piece 32 can be a Hall element, a coil, a reed switch, a fluxgate sensor, etc., but not limited thereto.

[0045] In some embodiments, the wire body 200 has an interface 202 for connecting the external device. The interface 202 is provided with a charging circuit 103, and the charging circuit 103 is electrically connected with the main controller 40. The main controller 40 can obtain the charging information of the charging circuit 103, so as to determine the electrical working state of the wire body 200.

[0046] The protocol IC in the charging circuit 103 is connected to the main controller 40 through I_C1. The charging circuit 103 also charges external devices through C1, and the main controller 40 and the protocol IC are respectively connected to the external devices through I2C1. The protocol IC also supplies power to the main controller 40 through VDRV1.

[0047] In some embodiments, the wire body 200 can be a data line. The interface 202 of the wire body 200 is also the interface of the data line. The specific model of the data line is not limited in the embodiments of the present application, and can be selected according to actual needs. The interface of the data line can be used to connect external devices, wherein the external devices can be a mobile phone, a computer, a Bluetooth headset charging box, a power bank, an electric vehicle, an electric motorcycle, but are not limited thereto.

[0048] The number of interfaces 202 of the wire body 200 is not limited in the embodiments of the present application. The number of interfaces 202 can be one or more, for example, the number of interfaces 202 can be 1, two, 3, 4, 5, 6 or 8, but is not limited thereto. When the number of interfaces 202 of the wire body 200 is one, the type of the interface 202 includes but is not limited to one of a USB interface, a type-C interface and a type-A interface; when the number of interfaces 202 of the wire body 200 is multiple, the types of the multiple interfaces 202 can be the same or different, and the types of the multiple interfaces 202 include but are not limited to one or more of a USB interface, a type-C interface and a type-A interface.

[0049] Please refer to FIGS. 5 to 6, in some embodiments, the winding assembly 101 includes a base 10 and a winding component 20. The base 10 has a first bearing surface 11. The winding component 20 includes a winding frame 21, a locking piece 22 and a first driving piece 23. The winding frame 21 is rotatably arranged on one side of the base 10 having the first bearing surface 11. The surface of the winding frame 21 facing the first bearing surface 11 is formed with a first clamping groove 21a. The locking piece 22 is rotatably arranged on the first bearing surface 11 and used to be buckled with the first clamping groove 21a to lock the winding frame 21. The first driving piece 23 is used to drive the winding frame 21 to rotate relative to the base 10.

[0050] The base 10 is used as a carrier for bearing other components in the winding mechanism 100, and the specific shape and material of the base 10 are not limited in the embodiments of the present application, and can be reasonably selected according to actual needs.

[0051] The first bearing surface 11 of the base 10 can be a plane, a curved surface or a combination of a plane and a curved surface, but is not limited thereto, as long as the first bearing surface 11 can be used to bear the winding frame 21 and the locking piece 22 and the like.

[0052] The winding frame 21 is rotatably arranged on the first bearing surface 11. The winding frame 21 is a structure for winding the wire body 200, and a first clamping groove 21a is formed on the surface of the winding frame 21 facing the first bearing surface 11 of the base 10. A locking member 22 is arranged between the first bearing surface 11 of the base 10 and the winding frame 21, and is rotatably arranged on the first bearing surface 11. During the process of pulling out the wire body 200 from the winding frame 21, the wire body 200 can drive the winding frame 21 to rotate, so that after the wire body 200 is pulled out to a certain length or completely pulled out, the first clamping groove 21a can be engaged with the locking member 22 to lock the winding frame 21. A first driving member 23 is connected to the winding frame 21 and the base 10. The first driving member 23 is used to drive the winding frame 21 to rotate relative to the base 10 after the locking member 22 is disengaged from the first clamping groove 21a.

[0053] In some embodiments, the first driving member 23 can be connected to the main controller 40 and drive the winding frame 21 under the control of the main controller 40. For example, when the wire body 200 is wound on the winding frame 21, the first driving member 23 can drive the winding frame 21 to rotate under the control of the main controller 40, so that the wire body 200 is automatically disengaged from the winding frame 21; after the locking member 22 is disengaged from the first clamping groove 21a, the first driving member 23 can drive the winding frame 21 to rotate under the control of the main controller 40, so that the wire body 200 is automatically wound on the winding frame 21.

[0054] In some embodiments, the main controller 40 is also used to generate a winding control signal when the working state meets the winding condition. The detection assembly 102 further comprises a rotating member 43 and a second driving member 42 connected to the rotating member 43. The second driving member 42 is connected to the main controller 40, and the second driving member 42 is used to drive the rotating member 43 to rotate under the control of the winding control signal, so as to disengage the locking member 22 from the first clamping groove 21a, and drive the winding frame 21 to rotate relative to the base 10 under the driving of the first driving member 23, so as to wind the wire body 200 on the winding frame 21.

[0055] The main controller 40 generates a winding control signal when the working state of the wire body 200 meets the winding condition, and the second driving member 42 drives the rotating member 43 to rotate in response to the winding control signal generated by the main controller 40. The rotating member 43 drives the locking member 22 to disengage from the first clamping groove 21a in the rotating process. After the locking member 22 disengages from the first clamping groove 21a, the winding frame 21 rotates relative to the base 10 under the drive of the first driving member 23 to drive the wire body 200 to be wound on the winding frame 21, so as to realize automatic winding of the wire body 200 on the winding frame 21. Compared with the related art, the winding of the wire body 200 is realized by manually pulling the wire body 200 or manually triggering, which saves the manual triggering process and avoids the problem that the wire body 200 cannot be wound. At the same time, the automatic winding of the wire body 200 can be realized without any operation on the winding assembly 101, which not only improves the convenience of winding the wire body 200, but also improves the efficiency of winding the wire body 200, thereby improving the user experience.

[0056] The main controller 40 automatically controls the winding assembly 101 to automatically wind the wire body 200 when it is determined that the working state of the wire body 200 meets the winding condition, that is, the main controller 40 directly controls the winding assembly 101 to wind the wire body 200 by the working state of the wire body 200, so as to realize automatic winding of the wire body 200 and improve the winding efficiency of the wire body 200.

[0057] In some embodiments, the detection assembly 102 further comprises a driving circuit 40a. The driving circuit 40a is electrically connected with the main controller 40 and the second driving member 42 respectively. The driving circuit 40a is used for the main controller 40 to drive the second driving member 42 to work in response to the generated winding control signal.

[0058] The driving circuit 40a can be a motor driving chip or a non-integrated discrete circuit. The driving circuit 40a can increase the driving capacity of the main controller 40 to the second driving member 42, so as to ensure the normal work of the second driving member 42.

[0059] Please refer to FIG. 7, and also refer to FIG. 4. The detection assembly 102 further comprises an electric control board 41. The main controller 40 is arranged on the electric control board 41. The electric control board 41 is arranged on the base 10. The electric control board 41 is provided with a first contact 414 and a second contact 415. The second driving member 42 is used to drive the rotating member 43 to rotate from the first contact 414 to the second contact 415 under the control of the winding control signal, so as to drive the locking member 22 to disengage from the first clamping groove 21a, and then rotate from the second contact 415 to the first contact 414, so as to reset to the first contact 414.

[0060] The rotating member 43 can be electrically connected with the main controller 40, or other conductive members can be driven to be electrically connected with the main controller 40, and the embodiment is described by taking the rotating member 43 electrically connected with the main controller 40 as an example. When the main controller 40 determines that the working state of the wire body 200 meets the winding condition, the main controller 40 generates a winding control signal, and the second driving member 42 drives the rotating member 43 to rotate from the first contact 414 to the second contact 415 in response to the winding control signal generated by the main controller 40, so as to actuate the locking member 22 to be separated from the first clamping groove 21a. When the rotating member 43 moves to the second contact 415, the rotating member 43 is in contact with the second contact 415, so that the main controller 40 is in conduction with the second contact 415, and it is determined that the rotating member 43 successfully actuates the locking member 22 to be separated from the first clamping groove 21a. Then, the main controller 40 controls the second driving member 42 to drive the rotating member 43 to rotate from the second contact 415 to the first contact 414. When the rotating member 43 rotates to the first contact 414, the rotating member 43 is in contact with the first contact 414, so that the main controller 40 is in conduction with the first contact 414 and controls the second driving member 42 to be closed.

[0061] After the rotating member 43 successfully actuates the locking member 22 to be separated from the first clamping groove 21a, the rotating member 43 is further rotated to be in contact with the second contact 415, so that the main controller 40 is in conduction with the second contact 415, so as to facilitate the main controller 40 to determine that the rotating member 43 can perform subsequent control steps after successfully actuating the locking member 22 to be separated from the first clamping groove 21a. On the one hand, it avoids the repeated control of the main controller 40 when it fails to identify whether the locking member 22 is successfully actuated to be separated from the first clamping groove 21a. On the other hand, it realizes the automatic winding of the wire body 200 and improves the winding efficiency of the wire body 200. After it is determined that the rotating member 43 successfully actuates the locking member 22 to be separated from the first clamping groove 21a, the main controller 40 controls the second driving member 42 to drive the rotating member 43 to reset to the first contact 414, so that the rotating member 43 is in conduction with the first contact 414 and the main controller 40, so as to facilitate the main controller 40 to confirm that the rotating member 43 is successfully reset and automatically control the second driving member 42 to be closed, thereby realizing the automatic closing of the second driving member 42, so that the second driving member 42 can be closed in time, avoiding the phenomenon of overheating or burning of the second driving member 42, and ensuring the service life of the second driving member 42.

[0062] The second driving member 42 can be an electric motor, an electric cylinder, a pneumatic cylinder, or a magnetic driving member, but is not limited thereto. The main controller can be a microcontroller, other control chips, etc.

[0063] In some embodiments, the electric control board 41 is further provided with a first trigger assembly 411 and a second trigger assembly 412. The first trigger assembly 411 and the second trigger assembly 412 each have a fixed end 4131 and a movable end 4132. The fixed end 4131 of the first trigger assembly 411 and the fixed end 4131 of the second trigger assembly 412 are both arranged on the electric control board 41 and located on the side of the first trigger assembly 411 and the second trigger assembly 412 close to each other.

[0064] The first trigger assembly 411 and the second trigger assembly 412 are arranged on the side of the electric control board 41 facing the rotating member 43 and correspond to the rotating member 43. The movable end 4132 of the first trigger assembly 411 is located at the end of the first trigger assembly 411 away from the second trigger assembly 412, and the movable end 4132 of the second trigger assembly 412 is located at the end of the second trigger assembly 412 away from the first trigger assembly 411. The second driving member 42 can drive the rotating member 43 to move from the movable end 4132 of the first trigger assembly 411 to the movable end 4132 of the second trigger assembly 412, or to move from the movable end 4132 of the second trigger assembly 412 to the movable end 4132 of the first trigger assembly 411. The locking member 22 can be arranged between the movable end 4132 of the first trigger assembly 411 and the movable end 4132 of the second trigger assembly 412, so that in the process of the second driving member 42 driving the rotating member 43 to move from the movable end 4132 of the first trigger assembly 411 to the movable end 4132 of the second trigger assembly 412, the rotating member 43 can push the locking member 22 to disengage from the first clamping groove 21a.

[0065] The present application does not limit the arrangement of the fixed end 4131 of the first trigger assembly 411 and the fixed end 4131 of the second trigger assembly 412 on the electric control board 41, for example, the arrangement of the fixed end 4131 of the first trigger assembly 411 and the fixed end 4131 of the second trigger assembly 412 on the electric control board 41 can be screw connection, bolt connection, buckle connection, magnetic attraction connection, adhesion or welding, but is not limited thereto.

[0066] In some embodiments, the take-up control signal includes a first control signal and a second control signal. The main controller 40 is connected with a first contact 414 and a second contact 415 respectively. The movable end 4132 of the first trigger assembly 411 is provided with a first sub-trigger member 4111 on the side facing the electric control board 41. The movable end 4132 of the second trigger assembly 412 is provided with a second sub-trigger member 4121 on the side facing the electric control board 41. The first sub-trigger member 4111 corresponds to the first contact 414, and the second sub-trigger member 4121 corresponds to the second contact 415.

[0067] The second sub-trigger 4121 is arranged at the active end 4132 of the second trigger assembly 412, and the second sub-trigger 4121 corresponds to the second contact 415, so that when the second driving member 42 drives the rotating member 43 to move to the active end 4132 of the second trigger assembly 412, the rotating member 43 can press the second trigger assembly 412 to make the second sub-trigger 4121 contact the second contact 415. The first sub-trigger 4111 is arranged at the active end 4132 of the first trigger assembly 411, so that when the second driving member 42 drives the rotating member 43 to move to the active end 4132 of the first trigger assembly 411, the rotating member 43 can press the first trigger assembly 411 to make the first sub-trigger 4111 contact the first contact 414.

[0068] The first trigger assembly 411 and the second trigger assembly 412 can be connected with the main controller 40. When the first sub-trigger 4111 contacts the first contact 414, the first contact 414 is conducted with the main controller 40 through the first trigger assembly 411. When the second sub-trigger 4121 contacts the second contact 415, the second contact 415 is conducted with the main controller 40 through the second sub-trigger 4121.

[0069] When the rotating member 43 rotates to the second contact 415 and presses the second trigger assembly 412 to make the second sub-trigger 4121 contact the second contact 415, the main controller 40 generates a first control signal, and the second driving member 42 drives the rotating member 43 to rotate towards the first trigger assembly 411 under the control of the first control signal. When the rotating member 43 rotates to the first contact 414 and presses the first trigger assembly 411 to make the first sub-trigger 4111 contact the first contact 414, the main controller 40 generates a second control signal, and the second driving member 42 is closed under the control of the second control signal. On the one hand, the automatic winding and resetting of the line body 200 are realized, and the winding efficiency of the line body 200 is improved. On the other hand, the automatic starting and closing of the second driving member 42 are realized, the energy consumption of the second driving member 42 is reduced, the second driving member 42 can be closed in a short time, so that the second driving member 42 will not appear the phenomenon of overheating or burning, and the service life of the second driving member 42 is guaranteed.

[0070] In some embodiments, the fixed end 4131 of the first trigger component 411 and the second trigger component 412 each comprises a fixed part 4131a and a bent part 4131b. The fixed part 4131a is arranged on the electric control board 41. One side of the bent part 4131b is connected to the fixed part 4131a, and the other side extends away from the electric control board 41 and bends towards one side. It can be understood that one side of the bent part 4131b of the first trigger component 411 is connected to the fixed part 4131a of the first trigger component 411, and the other side extends away from the electric control board 41 and bends away from the second trigger component 412; one side of the bent part 4131b of the second trigger component 412 is connected to the fixed part 4131a of the second trigger component 412, and the other side extends away from the electric control board 41 and bends away from the first trigger component 411.

[0071] The active end 4132 of the first trigger component 411 and the second trigger component 412 is located at the end away from each other, and is arranged away from the electric control board 41. The distance between the first trigger component 411 and the electric control board 41 and the distance between the second trigger component 412 and the electric control board 41 gradually increase in the direction from the fixed end 4131 to the active end 4132. Alternatively, the bent part 4131b of the first trigger component 411 and the second trigger component 412 can be wavy or arc-shaped, and the distance between the first trigger component 411 and the electric control board 41 and the distance between the second trigger component 412 and the electric control board 41 increase in a wavy manner in the direction from the fixed end 4131 to the active end 4132.

[0072] In some embodiments, the first trigger component 411 and the second trigger component 412 can have a certain elasticity, and the first trigger component 411 and the second trigger component 412 can be elastic sheets or springs.

[0073] By arranging the fixed end 4131 of the first trigger component 411 and the second trigger component 412 on the electric control board 41, and arranging the active end 4132 away from the electric control board 41, and gradually increasing or increasing in a wavy manner the distance between the first trigger component 411 and the electric control board 41 and the distance between the second trigger component 412 and the electric control board 41 in the direction from the fixed end 4131 to the active end 4132, and because the first trigger component 411 and the second trigger component 412 have a certain elasticity, when the active end 4132 away from the electric control board 41 is pressed by the rotating member 43, the active end 4132 will move towards the electric control board 41 to make the first sub-trigger component 4111 contact the first contact 414 or make the second sub-trigger component 4121 contact the second contact 415.

[0074] The distance between the first trigger assembly 411 and the electric control board 41 and the distance between the second trigger assembly 412 and the electric control board 41 gradually increase or fluctuate in the direction from the fixed end 4131 to the movable end 4132, so that the second driving member 42 only needs to drive the rotating member 43 to rotate to realize the compression of the first trigger assembly 411 and the second trigger assembly 412, without driving the rotating member 43 to move up and down, which simplifies the structure of the winding mechanism 100 and the control process of the rotating member 43, and improves the working efficiency of the winding mechanism 100.

[0075] In some embodiments, the main controller 40 is further configured to determine whether the first sub-trigger member 4111 is in contact with the first contact 414 before the rotating member 43 is rotated from the first contact 414 to the second contact 415 when the working state meets the winding condition. If yes, the main controller 40 generates a third control signal, and the second driving member 42 drives the rotating member 43 to rotate towards the second contact 415 under the control of the third control signal.

[0076] When the main controller 40 determines that the working state of the wire body 200 meets the winding condition, the main controller 40 first determines whether the first contact 414 is conductive with the main controller 40. If the first contact 414 is not conductive with the main controller 40, it indicates that the first sub-trigger member 4111 is not in contact with the first contact 414, and the rotating member 43 is not currently at the first contact 414. At this time, the second driving member 42 needs to drive the rotating member 43 to return to the first contact 414, so that the rotating member 43 can obtain enough potential energy to drive the locking member 22 to move away from the first clamping groove 21a during the rotation of the rotating member 43 towards the second contact 415. If the first contact 414 is conductive with the main controller 40, it indicates that the first sub-trigger member 4111 is in contact with the first contact 414, and the rotating member 43 is not currently at the first contact 414. At this time, the main controller 40 generates a third control signal, and the second driving member 42 drives the rotating member 43 to rotate towards the second contact 415 under the control of the third control signal.

[0077] In some embodiments, the main controller 40 is further configured to determine whether the second driving member 42 is abnormal, and if yes, control the second driving member 42 to be closed, and the rotating member 43 is rotated under external operation.

[0078] When the working state of the online body 200 meets the winding condition, the main controller 40 controls the second driving member 42 to drive the rotating member 43 to rotate from the first contact point 414 to the second contact point 415. If the main controller 40 and the second contact point 415 are not connected after more than the second preset time, but the current of the second contact point 415 is very large, for example, more than 200 mA, it indicates that the second sub-trigger member 4121 does not contact the second contact point 415, and the rotating member 43 does not move to the second contact point 415. At this time, the main controller 40 determines that the second driving member 42 is working abnormally, and triggers the stall protection mechanism to control the second driving member 42 to be closed. After the second driving member 42 is closed, the rotating member 43 can be driven to rotate manually or by other tools to make the rotating member 43 disengage the locking member 22 from the first clamping groove 21a, so as to realize manual winding.

[0079] Please refer to FIG. 8, in some embodiments, the second driving member 42 can drive the rotating member 43 to move close to or away from the control panel 41. The first trigger assembly 411 and the second trigger assembly 412 each include a mounting plate 416, a slide rod 417, an abutting portion 418, and a reset member (not shown in the figure). The mounting plate 416 is arranged on the side of the control panel 41 facing the rotating member 43. The slide rod 417 is arranged on the mounting plate 416. One end of the abutting portion 418 is slidably arranged on the slide rod 417, and the other end extends towards a side to correspond to the contact point on the control panel 41, that is, one end of the abutting portion 418 of the first trigger assembly 411 is slidably arranged on the slide rod 417, and the other end extends towards the direction of the first contact point 414. One end of the abutting portion 418 of the second trigger assembly 412 is slidably arranged on the slide rod 417, and the other end extends towards the direction of the second contact point 415. The abutting portion 418 of the first trigger assembly 411 is provided with a first sub-trigger member 4111 corresponding to the first contact point 414 on the side of the control panel 41. The abutting portion 418 of the second trigger assembly 412 is provided with a second sub-trigger member 4121 corresponding to the second contact point 415 on the side of the control panel 41. The reset member is sleeved on the slide rod 417 and located between the abutting portion 418 and the mounting plate 416. The abutting portion 418 can move along the slide rod 417 between a first position and a second position, wherein the first position is the position of the abutting portion 418 when the first sub-trigger member 4111 contacts the first contact point 414 and the second sub-trigger member 4121 contacts the second contact point 415, and the second position is the position of the abutting portion 418 when the distance between the abutting portion 418 and the control panel 41 reaches the maximum.

[0080] When the main controller 40 controls the second driving member 42 to drive the rotating member 43 to rotate from the second contact point 415 to the first contact point 414, the second driving member 42 can drive the rotating member 43 to move towards the electric control board 41 to push the abutting part 418 of the second trigger assembly 412 to move along the slide rod 417 from the second position to the first position, so that the second sub-trigger member 4121 contacts the second contact point 415. During the process that the rotating member 43 pushes the abutting part 418 to move from the second position to the first position, the restoring force of the reset member between the abutting part 418 and the mounting plate 416 is compressed and stored towards the abutting part 418. After the second sub-trigger member 4121 contacts the second contact point 415, the main controller 40 controls the second driving member 42 to drive the rotating member 43 to move towards the direction away from the electric control board 41, and at the same time, the reset member resets and pushes the abutting part 418 to move along the slide rod 417 from the first position to the second position. When the main controller 40 controls the second driving member 42 to drive the rotating member 43 to rotate from the second contact point 415 to the first contact point 414, the second driving member 42 can drive the rotating member 43 to move towards the electric control board 41 to push the abutting part 418 of the first trigger assembly 411 to move along the slide rod 417 from the second position to the first position, so that the first sub-trigger member 4111 contacts the first contact point 414. During the process that the rotating member 43 pushes the abutting part 418 to move from the second position to the first position, the restoring force of the reset member between the abutting part 418 and the mounting plate 416 is compressed and stored towards the abutting part 418. After the first sub-trigger member 4111 contacts the first contact point 414, the main controller 40 controls the second driving member 42 to drive the rotating member 43 to move towards the direction away from the electric control board 41 and closes the second driving member 42, and at the same time, the reset member resets and pushes the abutting part 418 to move along the slide rod 417 from the first position to the second position.

[0081] Please refer to FIG. 9, one end of the rotating member 43 is formed with a cylinder 431, and the other end is formed with a pressing part 432. The cylinder 431 is used to accommodate the second driving member 42. The second driving member 42 is provided with a driving shaft 421 towards one side of the bottom of the cylinder 431. The bottom of the cylinder 431 is provided with a first through hole 431a matched with the driving shaft 421, and the driving shaft 421 is arranged in the first through hole 431a to drive the rotating member 43 to rotate. The pressing part 432 is used to press the first trigger assembly 411 and the second trigger assembly 412.

[0082] The rotating member 43 comprises a cylinder body 431, an extension part 433 and a pressing part 432 connected in sequence. It can be understood that the cylinder body 431 is formed at one end of the extension part 433, and the pressing part 432 is formed at the other end of the extension part 433. The pressing part 432 is used to press the first trigger assembly 411 and the second trigger assembly 412. The first trigger assembly 411 and the second trigger assembly 412 will be elastically deformed under the pressure of the pressing part 432, so that the movable end 4132 of the first trigger assembly 411 and the second trigger assembly 412 can move towards the direction of the electric control panel 41. The cylinder body 431 can be a cylinder, and the cylinder body 431 is used to accommodate the second driving member 42. By passing the driving shaft 421 of the second driving member 42 through the first through hole 431a, the second driving member 42 can drive the rotating member 43 to rotate.

[0083] The cylinder body 431, the extension part 433 and the pressing part 432 can be a formed structure, that is, the rotating member 43 can be a one-piece structure.

[0084] Please refer to FIGS. 10-12, the base 10 also has a second bearing surface 12 arranged opposite to the first bearing surface 11. The base 10 is formed with a slot 112 penetrating through the first bearing surface 11 and the second bearing surface 12. The cylinder body 431 is rotatably arranged on the first bearing surface 11. The electric control panel 41 is arranged on the second bearing surface 12, and the first trigger assembly 411 and the second trigger assembly 412 correspond to the slot 112. The pressing part 432 passes through the slot 112.

[0085] The second bearing surface 12 can be a plane, a curved surface or a combination of a plane and a curved surface, but is not limited thereto, as long as the second bearing surface 12 can be used to bear components such as the electric control panel 41.

[0086] The slot 112 is a through slot penetrating through the first bearing surface 11 and the second bearing surface 12. The cylinder body 431 is rotatably arranged on the first bearing surface 11 and located on the side of the slot 112 away from the central axis of the base 10. By rotatably arranging the cylinder body 431 on the first bearing surface 11 of the base 10 facing the reel 21, arranging the electric control panel 41 on the second bearing surface 12 of the base 10 facing away from the reel 21, and forming the slot 112 penetrating through the first bearing surface 11 and the second bearing surface 12 and corresponding to the first trigger assembly 411 and the second trigger assembly 412, the pressing part 432 can pass through the slot 112 and rotate along the slot 112 under the action of the second driving member 42, that is, the second driving member 42 can drive the rotating member 43 to rotate along the slot 112 from the first trigger assembly 411 to the second trigger assembly 412, or from the second trigger assembly 412 to the first trigger assembly 411.

[0087] By setting the rotating member 43 and the second driving member 42 on the first bearing surface 11, setting the electric control board 41 on the second bearing surface 12, and opening the slot 112 penetrating through the first bearing surface 11 and the second bearing surface 12 and corresponding to the first trigger assembly 411 and the second trigger assembly 412, the pressing part 432 of the rotating member 43 can be arranged in the slot 112 to press the first trigger assembly 411 and the second trigger assembly 412, and the slot 112 can limit the rotating member 43, which can prevent the rotating member 43 from shaking during rotation, and can make the rotating member 43 press the first trigger assembly 411 and the second trigger assembly 412 accurately, thereby improving the stability and rotation efficiency of the rotating member 43.

[0088] In some embodiments, the first bearing surface 11 is formed with a recess 111, and the recess 111 is located on the side of the slot 112 away from the central axis of the base 10. The recess 111 is used to accommodate the barrel 431 of the rotating member 43. The rotating member 43 can rotate relative to the recess 111, and the recess 111 can limit the barrel 431 to prevent the rotating member 43 from shaking during rotation, so that the rotating member 43 can rotate stably.

[0089] In some embodiments, the first bearing surface 11 is provided with a limiting groove 113, and the slot 112 is located in the limiting groove 113.

[0090] The limiting groove 113 is a recess with an opening facing the reel 21. The recess 111 and the slot 112 are both formed on the groove bottom wall of the limiting groove 113, and the recess 111 is located on the side of the slot 112 away from the central axis of the base 10. After the reel 21 is arranged on the first bearing surface 11, the orthographic projection of the reel 21 on the first bearing surface 11 is offset from the recess 111, so that the arrangement of the reel 21 does not occupy the arrangement space of the second driving member 42 and the rotating member 43. After the reel 21 and the rotating member 43 are arranged on the base 10, the reel 21 and the rotating member 43 are arranged in a spaced manner, so that the rotating member 43 and the reel 21 can rotate independently and do not interfere with each other.

[0091] In some embodiments, the locking member 22 includes a locking body 221 and a locking protrusion 222. The locking body 221 is arranged in the limiting groove 113, and one end of the locking body 221 extends to the slot 112. The locking protrusion 222 is arranged on the other end of the locking body 221 and located on the side of the locking body 221 facing the reel 21. The locking protrusion 222 is used to be buckled with the first clamping groove 21a to lock the reel 21.

[0092] The locking body 221 is embedded in the limiting groove 113 and is rotationally connected with the groove bottom wall of the limiting groove 113. The locking body 221 can be rotationally connected with the groove bottom wall of the limiting groove 113 through a bearing, a pin shaft, a rotating shaft or the like. One end of the locking body 221 extends to the slotted groove 112, and the locking protrusion 222 is arranged at the other end of the locking body 221. The locking protrusion 222 is arranged at the side of the locking body 221 facing the reel 21. When the wire body 200 is connected with an external device, the locking protrusion 222 is engaged with the first clamping groove 21a on the surface of the reel 21 facing the first bearing surface 11 to lock the reel 21. By extending one end of the locking body 221 to the slotted groove 112, the second driving member 42 can facilitate the process of driving the rotating member 43 to rotate along the slotted groove 112 from the first trigger assembly 411 to the second trigger assembly 412, and the locking body 221 is disengaged from the first clamping groove 21a.

[0093] The locking body 221 and the locking protrusion 222 can be an integral molding structure. The integral molding manner of the locking body 221 and the locking protrusion 222 can be injection molding, milling molding or 3D printing molding, but is not limited thereto. Of course, the locking body 221 and the locking protrusion 222 can also be a fixed connection structure. The fixed connection manner of the locking body 221 and the locking protrusion 222 can be screw connection, bolt connection, buckle connection, magnetic adsorption connection, bonding or welding, but is not limited thereto.

[0094] In some embodiments, the limiting groove 113 has an arc-shaped groove side wall 1131 arranged around the rotation axis of the locking member 22. The other end of the locking body 221 is in contact with the arc-shaped groove side wall 1131. In the working state of the wire body 200 satisfying the winding condition, the second driving member 42 drives the rotating member 43 to rotate along the slotted groove 112, and drives the locking body 221 to rotate along the arc-shaped groove side wall 1131 to disengage the locking protrusion 222 from the first clamping groove 21a.

[0095] The other end of the locking body 221 can be in point contact, line contact or surface contact with the arc-shaped groove side wall 1131. By arranging the arc-shaped groove side wall 1131, when the locking body 221 rotates under the action of the rotating member 43, the other end of the locking body 221 is in contact with the arc-shaped groove side wall 1131, which can effectively enhance the stability of the movement of the locking body 221, so that the locking protrusion 222 can quickly disengage from the first clamping groove 21a.

[0096] In some embodiments, the first bearing surface 11 has a mounting hole 11a. The winding frame 21 comprises a rotating shaft 211 and a bracket 212 fixedly connected with the rotating shaft 211. The first clamping groove 21a is located on the bracket 212. The bracket 212 further has an annular guide groove 21b formed on the surface thereof facing the first bearing surface 11. The mounting hole 11a is in communication with the second bearing surface 12 and the first bearing surface 11. The rotating shaft 211 is arranged in the mounting hole 11a and rotationally connected with the base 10.

[0097] It can be understood that the first clamping groove 21a and the annular guide groove 21b are both formed on the surface of the bracket 212 facing the first bearing surface 11. The specific shape and trajectory of the annular guide groove 21b are not limited in the embodiments of the present application and can be reasonably designed according to actual needs. The locking member 22 is located between the first bearing surface 11 and the bracket 212, and the locking member 22 is at least partially embedded in the annular guide groove 21b. The first clamping groove 21a is a groove segment in the annular guide groove 21b that can be engaged with the locking member 22 to fix the position of the bracket 212 relative to the base 10. The locking member 22 is a structural member for fixing the position of the bracket 212 relative to the base 10, i.e., the bracket 212 and the base 10 are fixed in position relative to each other by the engagement of the locking member 22 with the first clamping groove 21a, so that when the working state of the wire body 200 does not meet the winding condition, the wire body 200 cannot be wound on the winding frame 21, and thus the external device can stably charge or communicate. The first clamping groove 21a is in communication with the annular guide groove 21b, so that the locking member 22 can be disengaged from the first clamping groove 21a and moved to the annular guide groove 21b under the actuation of the rotating member 43.

[0098] The rotating shaft 211 and the bracket 212 are fixedly connected or integrally formed. The fixed connection between the rotating shaft 211 and the bracket 212 can be achieved by bolt connection, screw connection, buckle connection, adhesion or plug-in connection, but is not limited thereto. The rotating shaft 211 and the bracket 212 can be integrally formed by injection molding or 3D printing, but are not limited thereto. One end of the wire body 200 is fixedly connected with and wound around the bracket 212, and the other end of the wire body 200 extends outward from the bracket 212, and the interface 202 is arranged on the other end of the wire body 200.

[0099] In some embodiments, the first driving member 23 can be a coil spring 231. The coil spring 231 is arranged on the side of the base 10 having the second bearing surface 12. The fixed end 2311 of the coil spring 231 is clamped and connected with the base 10, and / or the movable end 2312 of the coil spring 231 is clamped and connected with the rotating shaft 211. When the coil spring 231 drives the winding frame 21 to rotate relative to the base 10, the locking member 22 can slide along the annular guide groove 21b.

[0100] The embodiments of the present application do not limit the specific connection mode between the movable end 2312 of the coil spring 231 and the rotating shaft 211 and between the fixed end 2311 of the coil spring 231 and the base 10, and reasonable devices can be made according to actual needs; for example, the movable end 2312 of the coil spring 231 and the rotating shaft 211 can be connected through bonding, clamping, bolt connection or plug-in connection, but are not limited thereto; the fixed end 2311 of the coil spring 231 and the base 10 can be connected through bonding, clamping, bolt connection or plug-in connection, but are not limited thereto.

[0101] In some embodiments, the first driving member 23 can be an electric motor. The output shaft of the electric motor is connected with the rotating shaft 211 for driving the winding frame 21 to rotate relative to the base 10.

[0102] Please refer to FIG. 13, one end of the rotating shaft 211 passing through the second bearing surface 12 of the base 10 is formed with a second clamping groove 211a. The second bearing surface 12 of the base 10 is provided with a surrounding plate 121. The surrounding plate 121 is annular. The annular surrounding plate 121 is arranged on the second bearing surface 12 to form a receiving portion 122 inside the surrounding plate 121, and the coil spring 231 is received in the receiving portion 122. The surrounding plate 121 is provided with a gap 121a. The end of the rotating shaft 211 formed with the second clamping groove 211a is located in the receiving portion 122, the movable end 2312 of the coil spring 231 is clamped in the second clamping groove 211a, and the fixed end 2311 of the coil spring 231 is clamped in the gap 121a. When the working state of the wire body 200 meets the winding condition, the second driving member 42 drives the rotating member 43 to rotate, and the rotating member 43 rotates to push the locking member 22 to move away from the first clamping groove 21a and to the annular guide groove 21b. At this time, when the coil spring 231 drives the winding frame 21 to rotate relative to the base 10, the locking member 22 can slide along the annular guide groove 21b, so as to realize the automatic winding of the wire body 200. Compared with the manual winding of the wire body in the related art by manually pulling the wire body 200, the process of manually pulling the wire body 200 is saved, and the convenience and efficiency of winding the wire body 200 are improved.

[0103] By arranging the coil spring 231, when the rotating member 43 pushes the locking member 22 to move away from the first clamping groove 21a, the wire body 200 is automatically wound under the elastic restoring force of the coil spring 231 around the axis of the rotating shaft 211, the structure is simple, and the winding efficiency is high. By arranging the coil spring 231 on one side of the base 10 with the second bearing surface 12, on the one hand, the mutual winding of the wire body 200 and the coil spring 231 during winding is effectively avoided, and on the other hand, the space on both sides of the base 10 can be fully utilized, the volume of the base 10 and the support 212 can be reduced, and thus the volume of the winding mechanism 100 is reduced.

The wire body 200 is clamped between the first frame body 2121 and the second frame body 2122. During the process of stretching or winding, the first frame body 2121 and the second frame body 2122 limit the wire body 200, which can effectively ensure the neatness of the wire body 200 wound on the rotating shaft 211, thereby effectively reducing the phenomenon of knotting of the wire body 200 during the process of stretching or winding, and improving the user experience.

[0106] The second frame body 2122 is located on the side of the first frame body 2121 away from the first bearing surface 11, that is, the first frame body 2121 is located on the side of the second frame body 2122 close to the first bearing surface 11.
