Description
Technical Field
[0001] The present application belongs to the technical field of data cables and relates to an electric retractable cable, and in particular to an electric retractable cable that can automatically retract. Background Art
[0002] In the prior art, with the popularization of electronic products, each electronic product has a data cable for charging or transmitting data. These data cables are relatively long and are easy to get messy and tangled when stored. Folding and bundling the data cables for storage will cause inconvenience in use. Providing a storage box on the data cable is a convenient storage method. When not in use, the data cable can be wound in the box and can be directly pulled out of the storage box when in use. It can also be pulled out to a suitable length according to needs. However, the existing storage boxes are all manual winding and cannot realize the function of automatic winding. Utility Model Content
[0003] In order to overcome the problems existing in the related art, the present application aims to provide an electric telescopic cable that can realize the function of automatic cable retraction.
[0004] The present application is implemented through the following technical solutions.
[0005] The technical solution is to provide an electric retractable cable, comprising a housing, a winding drum, a data cable, an elastic member, a rotating disk and a motor, wherein the winding drum is arranged inside the housing and rotates, and the data cable is wound on the winding drum;
[0006] The winding disc is provided with a corrugated inner tooth, the elastic member is provided in the corrugated inner tooth, the elastic member is provided with a deformation part and a convex tooth part provided on the deformation part, the rotating disc is drivingly connected with the motor, and the side of the rotating disc is provided with at least one convex part;
[0007] When the motor drives the turntable to rotate, the raised portion abuts against the deformation portion, and the convex tooth portion cooperates with the corrugated inner teeth to drive the winding disk to rotate; when the motor stops, the rotation of the winding disk can cause the deformation portion to deform, and the convex tooth portion and the corrugated inner teeth slide with a tooth feeling.
[0008] The electric telescopic cable of the present technical solution, when in the wire-reeling state, drives the turntable to rotate through the motor, and the turntable presses against the elastic member to make the convex tooth portion cooperate with the corrugated inner tooth, so that the winding drum and the turntable rotate together to realize electric wire-reeling and wind the data cable on the winding drum; when in the wire-releasing state, the motor stops working, the turntable is in free rotation and loses the press against the elastic member, and the winding drum rotates in the opposite direction when releasing the wire, and at the same time, the convex tooth portion and the corrugated inner tooth slide with a tooth feeling, so that the rotation positioning of the winding drum when releasing the wire is realized.
[0009] It should be noted that the wire winding state refers to the process in which the motor drives the turntable and the wire winding disc to rotate in the positive direction. In the wire winding state, the data cable is wound onto the wire winding disc, while the wire unwinding state is the process in which the wire winding disc rotates in the reverse direction when an external force pulls the data cable out of the wire winding disc after the motor stops working. The definition of the tooth feeling sliding is the process in which the convex tooth part slides from one tooth valley to another tooth valley on the corrugated inner tooth, and during this process, the deformation part provides an elastic force to keep the convex tooth part in contact with the corrugated inner tooth all the time.
[0010] In one or more embodiments, the deformation part of the elastic member is in an annular structure, the convex tooth part is located outside the deformation part, and the turntable is arranged inside the deformation part.

[0014] In one or more embodiments, the turntable is in an elliptical structure, the center of the turntable is connected to the rotating shaft of the motor, and the protruding part is arranged on the distal side surface of the turntable.
[0015] In one or more embodiments, a first wiring board and a second wiring board are further included. The first wiring board is connected to the wire winding disc, and the second wiring board is connected to the housing;
[0016] One end of the data cable is electrically connected to the first wiring board, the other end is a free end located outside the housing, and the first wiring board and the second wiring board are electrically connected through a brush.

Detailed Description of the Embodiment
[0031] Next, in combination with the accompanying drawings in some embodiments of the present application, the technical solutions in some embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0032] The technical solutions of the embodiments of the present application will be described in detail below in combination with the accompanying drawings.
[0033] As Figures 1 to 6 shown in, this embodiment is an electric telescopic wire, including a housing 11, a winding disc 13, a data wire 12, an elastic member 14, a turntable 15 and a motor 16. The winding disc 13 is arranged to rotate inside the housing 11, the data wire 12 is wound around the winding disc 13, the housing 11 is composed of two parts combined, a chamber for accommodating the winding disc 13, the data wire 12, the elastic member 14, the turntable 15 and the motor 16 is provided in the housing 11, an opening 111 for the data wire 12 to pass through the housing is provided on the housing 11, a rotating shaft 131 is provided on the winding disc 13, a shaft hole 112 is provided on the housing 11, and the winding disc 13 is fitted into the shaft hole 112 through the rotating shaft 131, so as to rotate inside the housing 11 around the rotation axis.
[0034] In this embodiment, a concave cavity 132 is provided at the center of the winding disc 13. The concave cavity 132 is a circular cavity. A corrugated inner tooth 133 is provided on the winding disc 13. The corrugated inner tooth 133 is formed on the side wall of the concave cavity 132, and the corrugated inner tooth 133 is coaxially arranged with the rotation axis of the winding disc 13. Among them, the corrugated inner tooth 133 means that the surfaces of each tooth peak and each tooth valley are all arc surfaces with smooth transitions.
[0035] In this embodiment, the elastic member 14 and the turntable 15 are accommodated in the concave cavity 132. The elastic member 14 includes a deformation part 141 and a convex tooth part 142 provided on the deformation part 141. The tip of the convex tooth part 142 has an arc surface. Exemplarily, the deformation part 141 of the elastic member 14 is an annular structure, such as a circular ring or an elliptical ring, etc. The convex tooth part 142 is located outside the deformation part 141, and the number of the convex tooth parts 142 is two, and the two convex tooth parts 142 are symmetrically arranged. In addition, the elastic member 14 can also be other geometric shapes or irregular shapes.
[0036] When the elastic member 14 is installed inside the corrugated inner tooth 133, the convex tooth part 142 is fitted into the tooth valley of the corrugated inner tooth 133. Whether it is a circular ring or an elliptical ring, at this time, the deformation part 141 will be compressed to present an elliptical ring shape and deform to generate an elastic acting force, so that the convex tooth part 142 is pressed tightly on the corrugated inner tooth 133, restricting and positioning the winding disc 13 to prevent the winding disc 13 from rotating by itself.
[0037] In this embodiment, the turntable 15 is disposed inside the deformed portion 141 of the elastic member 14. The rotation axis of the turntable 15 is coaxially arranged with the rotation axis of the wire winding disc 13. At least one convex portion 151 is provided on the side of the turntable 15. Since the structure of the convex portion 151 is blocked by the elastic member 14, the turntable 15 cannot rotate freely inside the elastic member 14. When the turntable 15 rotates, when the convex portion 151 rotates to a position near the convex tooth portion 142, the convex portion 151 will abut against the deformed portion 141, and through the cooperation of the convex tooth portion 142 and the corrugated internal teeth 133, the wire winding disc 13 is driven to rotate.
[0038] Exemplarily, as Figure 5 、 7 and shown in 8, the turntable 15 can be a circular structure, a structure similar to a polygon or an elliptical structure. The convex portion 151 is formed on the side of the turntable 15. The function of the convex portion 151 is to abut against the elastic member 14. For example, when the turntable 15 is a polygon structure similar to a triangle, a rectangle, etc., the convex portion 151 is located at its corner. When the turntable 15 is a circular structure, the convex portion 151 can be formed outward on the side.
[0039] As Figure 5 shown in, the turntable 15 is an elliptical structure. The center of the turntable 15 is connected to the rotating shaft 131 of the motor 16. The motor 16 drives the turntable 15 to rotate. The convex portion 151 is provided on the distal side surface of the turntable 15. The two ends of the two long radii of the turntable 15 are defined as the convex portions 151. The distance between the tops of the two convex portions 151, that is, the long radius of the ellipse, is defined as the first distance a, and the short radius of the ellipse on the inner surface of the deformed portion 141 of the elliptical ring is defined as the second distance b, where the first distance a is greater than the second distance b. When the motor 16 is in a stopped state, the abutting force of the turntable 15 on the elastic member 14 disappears. During the process of pulling the data cable 12 to pay out the wire, the rotation of the wire winding disc 13 can cause the deformed portion 141 to deform, and a tooth feeling sliding occurs between the convex tooth portion 142 and the corrugated internal teeth 133.
[0040] In this embodiment, during the rotation of the wire winding disc 13, the elastic member 14 does not rotate all the time. In order to limit the elasticity, a strip-shaped guiding hole 143 is provided on the convex tooth portion 142, and a guiding column 161 is provided on the motor 16. The guiding column 161 is disposed in the guiding hole 143. In this way, while limiting the non-rotation of the elastic member 14, the deformation direction of the deformed portion 141 of the elastic member 14 is also guided.
[0041] In this embodiment, the electric telescopic wire further includes a first wiring board 17 and a second wiring board 18. The first wiring board 17 is connected to the wire winding disc 13, and the second wiring board 18 is connected to the housing 11. One end of the data wire 12 is electrically connected to the first wiring board 17, and the other end is a free end located outside the housing 11. The free end is provided with a connector 121, such as a TYPE-C connector, an audio connector, etc. The first wiring board 17 and the second wiring board 18 are electrically connected through a brush 19.
[0042] Exemplarily, a ring-shaped contact conductive end 181 is provided on the surface of the second wiring board 18 facing the first wiring board 17. A brush 19 is provided on the first wiring board 17. The brush 19 is in sliding contact with the contact conductive end 181 to achieve electrical connection. A wiring pad 182 is provided on the second wiring board 18, and the wiring pad 182 can be used to connect another data wire. A first avoidance hole 171 for avoiding the motor 16 is provided on the first wiring board 17, and a second avoidance hole 183 for avoiding the motor 16 is provided on the second wiring board 18.
[0043] In the electric telescopic wire of this embodiment, in the wire winding state, the motor 16 works to drive the turntable 15 to rotate. The turntable 15 abuts against the elastic member 14 so that the convex tooth portion 142 cooperates with the corrugated internal teeth 133. In this way, the wire winding disc 13 and the turntable 15 are linked together to rotate, realizing electric wire winding to wind the data wire 12 around the wire winding disc 13.
[0044] After the motor 16 stops working and is in the wire unwinding state, the turntable 15 is in a free rotation state, releasing the abutment against the elastic member 14. The wire winding disc 13 can rotate in the reverse direction for wire unwinding. At the same time, a tooth feeling sliding occurs between the convex tooth portion 142 and the corrugated internal teeth 133 to realize the rotational positioning of the wire winding disc 13 during wire unwinding, and pull out an appropriate length according to requirements.
[0045] It should be noted that the wire winding state refers to the process in which the motor 16 drives the turntable 15 and the wire winding disc 13 to rotate in the positive direction. In the wire winding state, the data wire 12 is wound around the wire winding disc 13. The wire unwinding state is the process in which the wire winding disc 13 rotates in the reverse direction when an external force pulls the data wire 12 out of the wire winding disc 13 after the motor 16 stops working.
[0046] Tooth feeling sliding refers to the process in which the convex tooth portion 142 slides from one tooth valley to another on the corrugated internal teeth 133. During this process, the deformation portion 141 provides an elastic acting force to keep the convex tooth portion 142 in contact with the corrugated internal teeth 133 all the time. The convex tooth portion 142 with an arc-shaped surface tip and the corrugated internal teeth 133 with an arc-shaped surface valley peak make the tooth feeling sliding smoother.
[0047] The embodiments of the present application have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, the practical application, or the improvement of the technology in the market, or to enable other ordinary skill in the art to understand the embodiments disclosed herein.
