This application claims priority of Chinese Patent Application No. 202310840450.0 filed on Jul. 7, 2023, the entire contents of which are hereby incorporated by reference.
This application relates to the field of winding technologies, and in particular, to a cable winding structure.
In different scenarios, different lengths of cables, such as data cables, are required. For example, when a longer charging cable is required when a socket is farther away. However, an existing cable winding structure is not convenient enough for controlling a length of a cable, and requires control by a motor, to retract and pull the cable of a required length. In view of this, there is a need to provide a simpler and more reliable cable winding structure to implement free retraction and release of cables.
Embodiments of this application provide a cable winding structure, configured to conveniently retract and pull a cable.
An embodiment of this application provides a cable winding structure, including: a bottom shell, a rotating disc, and a surface shell that are sequentially arranged opposite to each other, where the surface shell covers the bottom shell;
Optionally, the reset magnet is two magnets whose magnetic poles have a same name and that are arranged axially symmetrically with respect to the magnetic toggle wheel; and
Optionally, the swing position of the magnetic toggle wheel is limited between mounting positions of the two reset magnets on the left and the right; and
Optionally, one end of the magnetic toggle wheel is a rounded structure, and an other end of the magnetic toggle wheel is a sharp-cornered structure, where
Optionally, a magnet with same magnetic poles as those of the reset magnet is mounted inside the sharp-cornered structure.
Optionally, a connecting column is arranged on a middle portion of the bottom shell, and the connecting column penetrates through the rotating disc and bears the surface shell.
Optionally, a winding mechanism is wound around a section of the connecting column that is located in the accommodating space, and the winding mechanism is configured to cooperate with the rotating disc to increase or reduce a length by which the cable is wound.
Optionally, the bottom shell and the surface shell cover each other through a snap-fit structure; and
Optionally, the snap-fit structure includes a recessed portion and a protruding portion that interlock with each other.
Optionally, the bottom shell, the rotating disc, and the surface shell are all made of plastic.
It can be learned from the foregoing technical solutions that the embodiments of this application have at least the following advantages.
The limiting track on the inner wall of the surface shell has a limiting effect on the magnetic toggle wheel, so that a specific length of the cable is stuck outside the accommodating space, to satisfy an actual cable length requirement of a user. When the cable needs to be wound and retracted, the magnetic toggle wheel can be separated from the limiting track by pulling the cable, and under the action of a magnetic force of the reset magnet, the magnetic toggle wheel may return to the swing position at which the magnetic toggle wheel does not abut against the limiting track, so that a specific length of the cable can be conveniently stuck or retracted a next time by limiting the magnetic toggle wheel. Therefore, the cable winding structure in the embodiments of this application can easily implement winding and storage of the cable, and make it convenient for a user to control an outlet length of the cable.

Referring to
The limiting track 21 on the inner wall of the surface shell 2 has a limiting effect on the magnetic toggle wheel 42, a specific length of the cable 3 is stuck outside the accommodating space, to satisfy an actual cable length requirement of a user. When the cable needs to be wound and retracted, the magnetic toggle wheel 42 can be separated from the limiting track 21 by pulling the cable 3, and under the action of a magnetic force of the reset magnet 41, the magnetic toggle wheel 42 may return to the swing position (referred to as returning to an original swing position) at which the magnetic toggle wheel 42 does not abut against the limiting track 21, so that a specific length of the cable 3 can be conveniently stuck or retracted a next time by limiting the magnetic toggle wheel. In view of the above, the cable winding structure in the embodiments of this application can conveniently implement winding of the cable 3 in the accommodating space. In addition, through mutual magnetism (for example, a force of mutual repulsion or a force of mutual attraction) between the reset magnet 41 and the magnetic toggle wheel 42, it is convenient to freely control an outlet length of the cable 3.
Based on the foregoing descriptions of examples, some specific possible implementation examples are provided below, and in an actual application, implementation content in the examples may be combined and implemented as needed according to corresponding functions, principles, and application logic.
As shown in
It may be understood that in some specific examples, the swing position of the magnetic toggle wheel 42 is limited between mounting positions of the two reset magnets 41 on the left and the right. When the magnetic toggle wheel 42 does not abut against the limiting track 21, the magnetic toggle wheel 42 faces toward the direction of the midline formed between the two reset magnets 41, and faces away from the center of a circle of the rotating disc 4, which may be referred to as an original swing position facing toward the middle between the two reset magnets 41 and facing away from the center of a circle of the rotating disc 4. For example, a swing angle of the magnetic toggle wheel 42 falls within an angle area formed by the two reset magnets 41 on the left and right, and does not tightly abut against the reset magnet 41 due to repulsion between magnets of the same poles. When the magnetic toggle wheel 42 does not abut against the limiting track 21, angles formed between the magnetic toggle wheel 42 (at the original swing position) and the two reset magnets 41 on the left and right may be regarded as 120°, that is, the three are arranged symmetrically with each other.
In some specific examples, one end of the magnetic toggle wheel 42 is a rounded structure, and an other end of the magnetic toggle wheel 42 is a sharp-cornered structure 421. The rounded structure is arranged on a surface of the rotating disc 4 through a rotation pivot 43. Preferably, the rotation pivot 43 is located in a midline region formed between the two reset magnets 41. A dimension of the sharp-cornered structure 421 is adapted to a track gauge of the limiting track 21, to enable the cable 3 to be stuck by the limited rotating disc 4. For example, the magnetic toggle wheel 42 may be in a shape of a water drop as shown in

As shown in
In some specific examples, the bottom shell 1 and the surface shell 2 cover each other through a snap-fit structure; and an opening for extending or retracting the cable 3 is provided on a shell wall of the bottom shell 1 and a shell wall of the surface shell 2. Further, the snap-fit structure includes a recessed portion and a protruding portion 12 that interlock with each other. The recessed portion or the protruding portion 12 may be distributed on the bottom shell 1 or the surface shell 2. The interlocking with each other may refer to as a covering relationship of a vertical press-fit type or rotary snap-fit type. Further, to reduce costs of consumables or a weight of a finished product, the bottom shell 1, the rotating disc 4, and the surface shell 2 may all be made of plastic.
In conclusion, the cable winding structure in the embodiments of this application properly utilizes the mutual magnetism (for example, a force of mutual repulsion) between magnets to control the required outlet length of the cable, so that the cable 3 can be easily and conveniently stored, which avoids inconvenience of requiring additional power such as an external power supply or a built-in battery, as in a conventional way, to run a motor and further control the outlet length of the cable, thereby facilitating mass manufacturing and use.
The foregoing embodiments are merely used for describing the technical solutions of this application, but are not intended to limit this application.
