Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0048] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present utility model. Therefore, the "in one embodiment" or "in an embodiment" that appears throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0049] As Figures 1 to 7 shown, the wire winding and unwinding device includes:

[0050] A wire winding assembly 1 and a control assembly 2 movably connected to the wire winding assembly 1;

[0051] The wire winding assembly 1 includes a wire winding wheel 11 and a driving member 12. The driving member 12 is drivingly connected to the wire winding wheel 11, and the driving member 12 drives the wire winding wheel 11 to rotate around the first axis L;

[0052] The wire winding runner 11 includes a receiving groove 111 and a limiting surface 112. The wire harness 7 is received in the receiving groove 111. Among them, the receiving groove 111 is arranged around the first axis L, the limiting surface 112 intersects with the first axis L, and the limiting surface 112 includes a limiting stop 1121;

[0053] The control component 2 is movably connected to the limiting surface 112. When the control component 2 abuts against the limiting stop 1121, the control component 2 restricts the wire winding runner 11 from rotating around the first axis L. When the control component 2 disengages from the limiting stop 1121, the wire winding runner 11 rotates.

[0054] As can be seen from the above embodiments, in the embodiments of the present invention, since the wire winding assembly 1 includes a wire winding runner 11 and a driving member 12, the driving member 12 is drivingly connected to the wire winding runner 11, the driving member 12 drives the wire winding runner 11 to rotate around the first axis L, and the wire winding runner 11 includes a receiving groove 111 and a limiting surface 112, and the wire harness 7 is received in the receiving groove 111. Therefore, the driving member 12 can drive the wire winding runner 11 to rotate around the first axis L, and the rotation of the wire winding runner 11 drives the winding and unwinding of the wire harness 7. Also, since the limiting surface 112 intersects with the first axis L, the limiting surface 112 includes a limiting stop 1121, and the control component 2 is movably connected to the limiting surface 112. When the control component 2 abuts against the limiting stop 1121, the control component 2 restricts the wire winding runner 11 from rotating around the first axis L. When the control component 2 disengages from the limiting stop 1121, the wire winding runner 11 rotates. Therefore, the state of rotation of the wire winding runner 11 can be controlled by the control component 2, and further the length of the winding and unwinding of the wire harness 7 can be controlled. To sum up, the wire winding and unwinding device provided by the embodiments of the present invention can not only realize the winding and unwinding of the wire harness 7, but also control the length of the winding and unwinding of the wire harness 7 during the process of winding and unwinding the wire harness 7, thereby reducing the risk of the wire harness 7 being broken due to complete winding and unwinding, and can reduce the risks such as winding and breaking of the wire harness 7, which is beneficial to the stable winding and unwinding of the wire harness 7.

[0055] Among them, in the above embodiments, the wire winding runner 11 is a rotating member having a rotating wheel surface and a rotating shaft 42. At the same time, the wire winding runner 11 can accommodate the wire harness 7, so that the wire harness 7 can be wound and unwound as the wire winding runner 11 rotates. The driving member 12 can be a circuit board motor structure, or a motor gear structure, or other driving structures that can achieve rotational driving. The embodiments of the present invention do not limit this. In addition, the wire winding runner 11 includes a receiving groove 111 and a limiting surface 112. The limiting surface 112 is located on one end surface of the wire winding runner 11 along the first axis L. The receiving groove 111 surrounds the first axis L, that is, the receiving groove 111 forms an annular groove structure. The groove depth of the receiving groove 111 is determined according to the number of turns of the wire harness 7 to be received.

[0056] In this way, driven by the driving member 12, the wire winding wheel 11 can be rotated in different directions, and thus, the wire harness 7 can be wound and unwound in different rotation directions. Exemplarily, when the wire winding wheel 11 rotates counterclockwise, the wire harness 7 can be disengaged from the accommodation groove 111, thereby realizing the unwinding of the wire harness 7. On the contrary, when the wire winding wheel 11 rotates clockwise, the wire harness 7 can be wound back into the accommodation groove 111, thereby realizing the winding of the wire harness 7.

[0057] In addition, a plurality of convex structures can be provided on the limiting surface 112. The plurality of convex structures form a beam-like structure, and some of the plurality of convex structures form a limiting stop 1121. In this way, on the one hand, the strength of the limiting surface 112 can be increased through the convex structures, and on the other hand, the rotation of the wire winding wheel 11 can be restricted through the limiting stop 1121. The number of the limiting stops 1121 can be one, two, four, or other numbers, and the embodiments of the present invention do not limit this. When the number of the limiting stops 1121 is at least two, the wire winding wheel 11 can be limited at different positions through the limiting stops 1121 at different positions. In some possible implementation manners, the plurality of limiting stops 1121 can be evenly distributed along the circumferential direction of the first axis L, so as to facilitate the flexible selection of the position where the wire winding wheel 11 stops, and the length control of the wire harness 7 is not limited.

[0058] The control component 2 movably connected to the limiting surface 112 can restrict the rotation of the wire winding wheel 11 around the axis L by pressing. Specifically, when the control component 2 abuts against the limiting stop 1121, the wire winding wheel 11 is restricted by the control component 2 and does not rotate in the first rotation direction. When the control component 2 disengages from the limiting stop 1121, the wire winding wheel 11 can rotate. In this way, it is convenient to control the length of the wire harness 7 during winding and unwinding, where the first rotation direction is the rotation direction intersecting with the plane where the limiting stop 1121 is located.

[0059] Next, the specific structure of the wire harness winding and unwinding device provided by the embodiments of the present invention will be introduced as follows:

[0060] In some embodiments, such as Figure 2 and Figure 4As shown, the winding assembly 1 further includes a winding bracket 13, and the control assembly 2 includes a braking lever 21; the winding wheel 11 is hinged to the winding bracket 13. The braking lever 21 includes a bent braking portion 211 and a pressing portion 212. The bent portion of the pressing portion 212 and the braking portion 211 is hinged to the winding bracket 13. The end of the pressing portion 212 away from the braking portion 211 is movably connected to the limiting notch 1121. When the end of the braking portion 211 away from the pressing portion 212 moves away from the winding wheel 11, the end of the pressing portion 212 away from the braking portion 211 presses against the limiting notch 1121. When the end of the braking portion 211 away from the pressing portion 212 moves towards the winding wheel 11, the end of the pressing portion 212 away from the braking portion 211 moves away from the limiting notch 1121.

[0061] In this embodiment, the winding bracket 13 is the main structure for fixing the winding wheel 11. The winding bracket 13 can be a plate-like structure. The winding bracket 13 includes a plurality of cross beams or a plurality of longitudinal beam structures, thereby improving the strength of the winding bracket 13. For the winding wheel 11 being hinged to the winding bracket 13, in an exemplary implementation manner, a rotating boss can be provided at the bottom of the winding wheel 11 (the end of the winding wheel 11 facing the winding bracket 13). The rotating boss can be a cylindrical structure. A hinged boss can be provided at the top of the winding bracket 13 (the end of the winding bracket 13 facing the winding wheel 11). The hinged boss can also be a cylindrical structure. Through the socket connection between the rotating boss and the hinged boss, the rotation of the rotating boss in the hinged boss is realized.

[0062] In addition, the braking lever 21 includes a bent braking portion 211 and a pressing portion 212. The bent portion of the pressing portion 212 and the braking portion 211 is hinged to the winding bracket 13. In an exemplary implementation manner, a hinged column can be provided at the top of the winding bracket 13 (the end of the winding bracket 13 facing the winding wheel 11). A hinged through hole is opened at the bent portion of the pressing portion 212 and the braking portion 211, and then the hinged column is passed through the hinged through hole, so that the bent portion of the pressing portion 212 and the braking portion 211 can rotate along the axis of the hinged column. That is, the pressing portion 212 and the braking portion 211 form a lever, and the fulcrum of the lever is at the bent portion of the pressing portion 212 and the braking portion 211.

[0063] In this way, through the above embodiment, when the end of the braking part 211 away from the pressing part 212 moves toward away from the winding wheel 11, the end of the pressing part 212 away from the braking part 211 presses on the limit stop 1121. When the end of the braking part 211 away from the pressing part 212 moves toward close to the winding wheel 11, the end of the pressing part 212 away from the braking part 211 is away from the limit stop 1121. In this way, through the control of the braking part 211, the relative position between the pressing part 212 and the limit stop 1121 can be switched, thereby realizing the control of the retraction and extension length of the wiring harness 7.

[0064] Furthermore, the control component 2 also includes an elastic member 22; one end of the elastic member 22 is connected to the end of the braking portion 211 away from the pressing portion 212, and the other end of the elastic member 22 is connected to the winding bracket 13; when the end of the pressing portion 212 away from the braking portion 211 is away from the limit stop 1121, the elastic member 22 is in an extended state.

[0065] It should be noted that the elastic member 22 can be a spring, a rubber member, or other structure that is deformable and can generate elastic force, and the embodiments of the present invention are not limited to this. Specifically, in the above embodiment, the elastic member 22 and the pressing portion 212 and the winding bracket 13 are assembled in an exemplary embodiment, taking the elastic member 22 as a spring as an example, the end of the winding bracket 13 can have a mounting plate extending toward the winding wheel 11, and a first connecting column can be provided on the mounting plate. A second connecting column is provided on the end of the braking portion 211 away from the pressing portion 212, one end of the spring is connected to the first connecting column, and the other end of the spring is connected to the second connecting column. In addition, the connecting portion 231 between the pressing portion 212 and the braking portion 211 can be a cylindrical structure, and the connecting portion 231 between the braking portion 211 can be located on different planes to facilitate the installation between the brake lever 21 and the winding bracket 13.

[0066] In this way, in this embodiment, since the end of the pressing portion 212 away from the braking portion 211 is away from the limit stop 1121, the elastic member 22 is in an extended state. Therefore, when it is necessary to make the end of the pressing portion 212 away from the braking portion 211 press against the limit stop 1121, the elastic force of the elastic member 22 can drive the end of the braking portion 211 away from the pressing portion 212 to move away from the winding wheel 11, thereby making the end of the pressing portion 212 away from the braking portion 211 press against the limit stop 1121, and after pressing against the limit stop 1121, under the action of the elastic member 22, the end of the pressing portion 212 away from the braking portion 211 will not separate from the limit stop 1121 without the action of external force, so that the control process of the length of the entire wiring harness 7 is smoother.

[0067] In some embodiments, the wire winding and unwinding device further includes an assembly housing 3; the wire winding assembly 1 and the control assembly 2 are accommodated in the inner cavity of the assembly housing 3.

[0068] It should be noted that the assembly housing 3 can be a housing-like structure with an inner cavity, so that the wire winding assembly 1 and the control assembly 2 are accommodated in the inner cavity of the assembly housing 3. Furthermore, the inner wire winding assembly 1 and the control assembly 2 can be protected by the assembly housing 3 to extend the service life of the wire winding and unwinding device.

[0069] Specifically, for the above embodiments, in some embodiments, the assembly housing 3 includes adjacent first side wall 31 and second side wall 32. Among them, the first side wall 31 is close to the braking portion 211, and the second side wall 32 is close to the pressing portion 212. A sliding through groove 311 is formed on the first side wall 31; the control assembly 2 further includes a push button 23, and the push button 23 is slidably connected in the sliding through groove 311. The push button 23 is connected to the end of the braking portion 211 away from the pressing portion 212; when the push button 23 slides in the direction close to the second side wall 32, the pressing portion 212 abuts against the limiting notch 1121, and when the push button 23 slides in the direction away from the second side wall 32, the pressing portion 212 disengages from the limiting notch 1121.

[0070] It should be noted that the first side wall 31 and the second side wall 32 are two adjacent side walls, that is, the plane where the first side wall 31 is located intersects with the plane where the second side wall 32 is located. Then, a sliding through groove 311 is formed on the first side wall 31, and the sliding through groove 311 runs through the first side wall 31. The push button 23 is slidably connected in the sliding through groove 311 so that the push button 23 can slide in the sliding groove. In this way, when the push button 23 slides in the direction close to the second side wall 32, the pressing portion 212 abuts against the limiting notch 1121, and when the push button 23 slides in the direction away from the second side wall 32, the pressing portion 212 disengages from the limiting notch 1121. Furthermore, a point where braking can be performed can be provided for the operator through the push button 23, which is convenient for controlling the length of the wire harness 7. In addition, the push button 23 can be fixed to the end of the braking portion 211 away from the pressing portion 212 by means of welding, clamping or bolt connection, etc. The embodiments of the present utility model do not limit this.

[0071] Optionally, for the structure of the push button 23, in some embodiments, the push button 23 includes a connecting portion 231 and a sliding portion 232; the sliding portion 232 is connected to the connecting portion 231, the connecting portion 231 is connected to the braking portion 211, the sliding portion 232 is slidably connected in the sliding through groove 311, and the end surface of the sliding portion 232 away from the braking portion 211 protrudes from the notch of the sliding through groove 311 away from the braking portion 211; wherein, the area of the orthographic projection of the sliding portion 232 on the first plane is smaller than the area of the orthographic projection of the sliding through groove 311 on the first plane, and the area of the orthographic projection of the connecting portion 231 on the first plane is larger than the area of the orthographic projection of the sliding through groove 311 on the first plane, and the first plane is a plane parallel to the plane where the first side wall 31 is located.

[0072] In this embodiment, for the structure of the push button 23, the push button 23 includes two parts. One part is the sliding portion 232 that can slide in the sliding through groove 311, and the other part is the connecting portion 231 connected to the braking portion 211. Since the end surface of the sliding portion 232 away from the braking portion 211 protrudes from the notch of the sliding through groove 311 away from the braking portion 211, it is convenient to provide a point where the operator can brake through the sliding portion 232. Also, since the area of the orthographic projection of the sliding portion 232 on the first plane is smaller than the area of the orthographic projection of the sliding through groove 311 on the first plane, and the area of the orthographic projection of the connecting portion 231 on the first plane is larger than the area of the orthographic projection of the sliding through groove 311 on the first plane, under the limitation of the connecting portion 231, the sliding portion 232 can be prevented from falling off from the sliding through groove 311, thereby ensuring the stability of the length adjustment of the wire harness 7.

[0073] Further, for the specific structure of the assembly housing 3, in some embodiments, the assembly housing 3 includes a middle frame ³³, an upper cover ³⁴ and a rear cover ³⁵; the middle frame ³³ is a housing-like structure with openings at both ends, the upper cover ³⁴ covers the opening at one end of the middle frame ³³, and the rear cover ³⁵ covers the opening at the other end of the middle frame ³³.

[0074] It should be noted that the middle frame ³³ is a frame-shaped structure, and both the upper cover ³⁴ and the rear cover ³⁵ can be plate-shaped structures. In this way, when the upper cover ³⁴ covers the opening at one end of the middle frame ³³ and the rear cover ³⁵ covers the opening at the other end of the middle frame ³³, the assembly housing 3 can form a hollow housing-like structure, which is convenient for protecting the internal winding component 1 and control component 2, so as to extend the service life of the wire harness retracting and deploying device.

[0075] Optionally, in some embodiments, as Figure 2 and Figure 5 shown, the wire harness retracting and deploying device further includes a winding rotating shaft 4; the winding rotating shaft 4 is hinged to the rear cover ³⁵, and the end of the wire harness 7 bypasses the winding rotating shaft 4 and extends out from the side wall of the middle frame ³³. Among them, the wire harness 7 between the winding rotating shaft 4 and the winding wheel 11 is in a straightened state.

[0076] In this embodiment, the wire harness 7 on one side of the winding rotating shaft 4 and the wire harness 7 on the other side of the winding rotating shaft 4 are arranged at an angle. In this way, during the winding and unwinding process of the wire harness 7, the wire harness 7 needs to pass through the winding rotating shaft 4. Under the action of the winding rotating shaft 4, the wire harness 7 between the winding rotating shaft 4 and the winding wheel 11 is in a straightened state, which can not only ensure that the wire harness 7 maintains a stable state during the winding and unwinding process, but also avoid phenomena such as wire entanglement, ensuring the normal winding and unwinding of the wire harness 7.

[0077] Regarding the structure of the winding rotating shaft 4, in some embodiments, the winding rotating shaft 4 includes a winding roller 41 and a rotating shaft 42; the end of the rotating shaft 42 is fixed on the rear cover 35, the winding roller 41 is sleeved on the rotating shaft 42, and the winding roller 41 rotates around the rotating shaft 42; the wire harness 7 is wound around the surface of the winding roller 41.

[0078] In this embodiment, the winding roller 41 is a cylindrical structure with a rotating surface. Since the end of the moving shaft is fixed on the rear cover 35, the winding roller 41 is sleeved on the rotating shaft 42 and the winding roller 41 rotates around the rotating shaft 42, so when the wire harness 7 is wound around the surface of the winding roller 41, in other words, when the wire harness 7 passes through the winding roller 41, it is wound into an arc surface with the same surface curvature as the surface of the winding roller 41. Furthermore, while ensuring that the wire harness 7 between the winding rotating shaft 4 and the winding wheel 11 is in a straightened state, it can avoid slipping during the winding and unwinding process of the wire harness 7, and can also avoid the winding roller 41 damaging the wire harness 7.

[0079] Optionally, a connector 5 is installed on the side wall of the middle frame 33, and an outlet hole is provided in the connector 5; the end of the wire harness 7 passes through the outlet hole. In this embodiment, the connector 5 can not only lead out the wire harness 7, but also facilitate the connection of the connector 5 with other wire harness 7 storage devices, facilitating the access of the wire harness 7.

[0080] Regarding the structure of the driving member 12, in some possible implementation manners, such as Figure 6 and Figure 7 as shown, the driving member 12 includes a circuit board 121 and a driving motor 122; the winding wheel 11 includes a wheel main body and a winding cover, a driving through hole is provided in the middle of the wheel main body, the winding cover covers the end face of the driving through hole, the driving motor 122 is embedded in the driving through hole and is electrically connected to the circuit board 121.

[0081] In this embodiment, the drive motor 122 can be first assembled in the drive through-hole opened in the middle of the runner body, and then the wire winding cover is covered on the end face of the drive through-hole, so as to limit the drive motor 122 through the wire winding cover. The drive motor 122 is embedded in the drive through-hole, so that the runner body can rotate with the rotation of the drive motor 122. The circuit board 121 is a control component for controlling the rotation of the drive motor 122, and then the rotation direction of the drive motor 122 is controlled through the circuit board 121 to realize the winding and unwinding of the wire harness 7, so that the process of winding and unwinding the wire harness 7 can be completed automatically.

[0082] Optionally, in some embodiments, as Figure 3 shown, the wire winding and unwinding device further includes at least one magnetic attraction member 6; the circuit board 121 further includes a charging terminal, and the magnetic attraction member 6 is arranged on at least one side close to the charging terminal.

[0083] It should be noted that since the device for supplying power or charging the circuit board 121 is usually a metal device, when the magnetic attraction member 6 is arranged on at least one side close to the charging terminal, the charging terminal can be adsorbed on the device for supplying power or charging, which is more beneficial to the recycling of the wire winding and unwinding device. In addition, it should also be noted that in the embodiment of the present invention, there is a gap between the wire winding bracket 13 and the assembly housing 3, so that the magnetic attraction member 6 is installed in this gap. At the same time, an outlet hole can be opened on the side wall of the assembly housing 3 close to the circuit board 121 to facilitate the charging terminal of the circuit board 121 to extend out of the assembly housing 3 through the outlet hole.

[0084] As can be seen from the above embodiments, in the embodiments of the present utility model, since the wire winding assembly 1 includes a wire winding wheel 11 and a driving member 12, the driving member 12 is drivingly connected to the wire winding wheel 11, and the driving member 12 drives the wire winding wheel 11 to rotate around the first axis L. The wire winding wheel 11 includes a receiving groove 111 and a limiting surface 112, and a wire harness 7 is received in the receiving groove 111. Therefore, the driving member 12 can drive the wire winding wheel 11 to rotate around the first axis L, and the rotation of the wire winding wheel 11 drives the winding and unwinding of the wire harness 7. Also, since the limiting surface 112 intersects the first axis L, the limiting surface 112 includes a limiting notch 1121, and the control assembly 2 is movably connected to the limiting surface 112. When the control assembly 2 abuts against the limiting notch 1121, the control assembly 2 restricts the wire winding wheel 11 from rotating around the first axis L. When the control assembly 2 disengages from the limiting notch 1121, the wire winding wheel 11 rotates. Therefore, the rotation state of the wire winding wheel 11 can be controlled by the control assembly 2, and further the length of the winding and unwinding of the wire harness 7 can be controlled. In summary, the wire winding and unwinding device provided by the embodiments of the present utility model can not only realize the winding and unwinding of the wire harness 7, but also control the length of the winding and unwinding of the wire harness 7 during the process of winding and unwinding the wire harness 7, thereby reducing the risk of the wire harness 7 breaking due to complete winding and unwinding, and reducing the risks of the wire harness 7 getting entangled or broken, which is beneficial to the stable winding and unwinding of the wire harness 7.
