[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.

[0035] As Figures 1 to 11 shown, a charging cable with a dynamic form-changing indicator according to this embodiment includes a first connector 1 and a second connector 2; the second connector 2 is electrically connected to the first connector 1 through a wiring harness 3; a receiving groove 11 is recessed on the surface of the first connector 1; the receiving groove 11 is circular; a charge and discharge indication module 4 is provided in the receiving groove 11;

[0036] The charge and discharge indication module 4 includes a rotating disk 41 rotatably provided in the receiving groove 11; the rotating disk 41 is disk-shaped; an elastic energy storage member 42 is provided between the rotating disk 41 and the first connector 1; a first indication unit 43 and two second indication units 44 symmetrically distributed on both sides of the first indication unit 43 are movably provided on the surface of the rotating disk 41; a switching member 45 is slidably penetrated through the rotating disk 41 along the radial direction; one ends of the two second indication units 44 are respectively hinged to the first indication unit 43 through a link 46; one end of the switching member 45 is hinged to the first indication unit 43; preferably, the switching member 45 is a rod-shaped structure;

[0037] The first connector 1 is provided with an arc groove 12 on the side wall of the receiving groove 11; the arc groove 12 is arranged eccentrically with the rotating disk 41; the other end of the switching member 45 can be movably inserted into the arc groove 12 after passing through the rotating disk 41 outward; under the action of the elastic energy storage member 42, the switching member 45 cooperates with the arc groove 12 to make the first indication unit 43 and the two second indication units 44 form a standby form;

[0038] The first connector 1 is provided with a driving component; the driving component is in transmission connection with the rotating disk 41 to drive the rotating disk 41 to rotate; the driving component is configured to: during charging, drive the rotating disk 41 to rotate in the first direction, so that the switching member 45 drives the first indicating unit 43 and the two second indicating units 44 to combine to form a charging state; during discharging, drive the rotating disk 41 to rotate in the second direction, so that the switching member 45 drives the first indicating unit 43 and the two second indicating units 44 to combine to form a discharging state. If the first direction is clockwise, the second direction is counterclockwise; if the first direction is counterclockwise, the second direction is clockwise.

[0039] For the convenience of explaining the present invention, in this embodiment, the first direction is clockwise and the second direction is counterclockwise for explanation; specifically, when the charging cable with a dynamically changing state indicator is in its initial state, the elastic energy storage member 42 exerts an elastic force on the rotating disk 41, so that the switching member 45 is located at the center position of the arc groove 12. At this time, the first indicating unit 43 and the two second indicating units 44 combine to form a standby state. At this time, the first indicating unit 43 and the second indicating unit 44 are parallel to each other, as Figure 3 shown, to indicate that the charging cable is in an idle state;

[0040] When the charging cable is charging, the driving component drives the rotating disk 41 to rotate clockwise, the elastic energy storage member 42 stores energy, the rotating disk 41 drives the switching member 45 to rotate clockwise synchronously. Since the arc groove 12 and the rotating disk 41 are not concentrically arranged, the switching member 45 is squeezed by the arc groove 12 and retracts radially inward, so that the switching member 45 makes the first indicating unit 43 and the two second indicating units 44 move synchronously and combine to form a charging state indicating the current direction, as Figure 4 shown, the first indicating unit 43 and the two second indicating units 44 combine to form a "<-" pattern, so that the user can intuitively see that the charging cable is in a charging state;

[0041] When discharging, the driving component drives the rotating disk 41 to rotate counterclockwise, the elastic energy storage member 42 stores energy, the rotating disk 41 drives the switching member 45 to rotate counterclockwise synchronously. Since the arc groove 12 and the rotating disk 41 are not concentrically arranged, the switching member 45 is squeezed by the arc groove 12 and retracts radially inward, so that the switching member 45 makes the first indicating unit 43 and the two second indicating units 44 move synchronously and combine to form a discharging state indicating the current direction, as Figure 5 shown, the first indicating unit 43 and the two second indicating units 44 combine to form a "->" pattern, so that the user can intuitively see that the charging cable is in a discharging state;

[0042] After the discharge or charging is completed, the elastic energy storage member 42 releases the stored energy, thereby driving the rotary disk 41 to reset to the initial position. The switching member 45 moves from the end of the arc groove 12 towards the center of the arc groove 12, and the switching member 45 extends outwards, thereby driving the first indicating unit 43 and the two second indicating units 44 to return to the standby state.

[0043] In this embodiment, by integrating a charge-discharge indication module 4 with variable forms on the charging cable, different graphic forms are presented in combination by the first indicating unit 43 and the two second indicating units 44 in different working states, so that the charge-discharge direction and state of the charging cable can be intuitively displayed, enabling users to identify without relying on the color of the light. It is especially suitable for use scenarios of users with strong light or color blindness / weak color vision, improving the user experience and convenience of use.

[0044] In some embodiments of the charging cable with a dynamic form-changing indicator of this embodiment, both the first indicating unit 43 and the second indicating unit 44 are indicators. With such a setting, the state of the charging cable can be judged through the combined graphic state of the indicators, and at the same time, it is convenient to penetrate the combined graphic state of the indicators in scenarios with strong light or dim light, making the structure more convenient to use.

[0045] As Figures 7 to 10 shown, in some embodiments of the charging cable with a dynamic form-changing indicator of this embodiment, the rotary disk 41 is provided with a sliding hole 411 along the radial direction; arc holes 412 are symmetrically arranged on both sides of the sliding hole 411 of the rotary disk 41; the first indicating unit 43 is slidably arranged on the sliding hole 411; the middle parts of the two second indicating units 44 are hinged to the rotary disk 41; an elastic member 47 is connected between the first indicating unit 43 and the rotary disk 41; a first hinge shaft 431 is provided at one end of the first indicating unit 43; second hinge shafts 441 are respectively provided at one ends of the two second indicating units 44; the two second hinge shafts 441 are respectively movably inserted into the corresponding arc holes 412; one end of the connecting rod 46 is hinged to the first hinge shaft 431, and the other end of the connecting rod 46 is hinged to the second hinge shaft 441; one end of the switching member 45 is hinged to the first hinge shaft 431.

[0046] Specifically, when the charging state of the charging cable is charging or discharging, the switching member 45 synchronously retracts inwards during rotation. The switching member 45 pushes the first indicating unit 43 to slide radially through the first hinge shaft 431, and the elastic member 47 deforms. The first hinge shaft 431 slides in the sliding hole 411. At the same time, the first hinge shaft 431 drives the second indicating unit 44 to move synchronously through the connecting rod 46 and the second hinge shaft 441 respectively. The second hinge shaft 441 approaches the first indicating unit 43 along the trajectory of the arc hole 412. In this way, the first indicating unit 43 and the second indicating unit 44 are combined to form an arrow-shaped graphic state, as Figure 4 and Figure 5As shown, it represents the charging state or the discharging state; a graphic form in the shape of an arrow is formed by combining the first indicating unit 43 and the second indicating unit 44, so that it is convenient for the user to directly judge the charging and discharging directions and states of the charging cable by observing the graphic form visually.

[0047] After the charging or discharging of the charging cable is completed, the elastic energy storage member 42 releases the stored energy, drives the rotary disk 41 to reset, the elastic member 47 pushes the first indicating unit 43 to reset, and the first indicating unit 43 pushes the second indicating unit 44 to reset through the first hinge shaft 431, the connecting rod 46 and the second hinge shaft 441, so that the second hinge shaft 441 moves away from the first indicating unit 43, thereby forming a standby state by combining the first indicating unit 43 and the second indicating unit 44, as Figure 3 shown.

[0048] As Figure 2 and Figure 8 shown, for the charging cable with a dynamic form-changing indicator in this embodiment, in some embodiments, the elastic energy storage member 42 is a coil spring; one end of the coil spring is fixedly connected to the rotary disk 41; the other end of the coil spring is fixedly connected to the first connector 1. The coil spring is adopted in this embodiment, and the structure is more compact.

[0049] As Figure 8 and Figure 10 shown, for the charging cable with a dynamic form-changing indicator in this embodiment, in some embodiments, the elastic member 47 is a spring; a sliding table 432 protrudes from the middle of the first indicating unit 43; a first sliding groove 414 is provided along the radial direction of the rotary disk 41; the sliding table 432 is slidably connected in the first sliding groove 414; the spring is arranged in the first sliding groove 414; both ends of the spring respectively abut against the groove wall of the first sliding groove 414 far from the switching member 45 and the sliding table 432. In this embodiment, by arranging the cooperation of the sliding table 432 and the first sliding groove 414, the movement of the first indicating unit 43 is more stable, and it is also convenient for the installation of the spring.

[0050] As Figures 7 to 9 , Figure 11 shown, for the charging cable with a dynamic form-changing indicator in this embodiment, in some embodiments, a limiting arc groove 13 concentric with the rotary disk 41 is further provided on the side wall of the accommodating groove 11; a limiting pin 413 is provided on the outer peripheral wall of the rotary disk 41; the limiting pin 413 is movably embedded in the limiting arc groove 13. In this embodiment, by arranging the cooperation of the limiting arc groove 13 and the limiting pin 413, the rotary disk 41 is limited and guided, so that the movement of the rotary disk 41 is more stable.

[0051] As Figure 2 and Figure 6As shown, in some embodiments, the charging cable with a dynamic form-changing indicator of this embodiment has at least a charging terminal 6 and a discharging terminal 7 disposed within the first connector 1. Of course, other functional terminals may also be provided within the first connector 1, which will not be described in detail here; the driving assembly includes a rotating column 51 rotatably disposed within the first connector 1 and a driven member 52 slidably disposed within the first connector 1 and made of a ferromagnetic material; the rotating column 51 is fixedly connected to the rotating disk 41; a first transmission structure is provided on the outer peripheral wall of the rotating column 51; the driven member 52 is provided with a second transmission structure in transmission connection with the first transmission structure; the driving assembly further includes a first electromagnet 53 electrically connected to the charging terminal 6 and a second electromagnet 54 electrically connected to the discharging terminal 7; the first electromagnet 53 and the second electromagnet 54 are distributed on both sides of the driven member 52.

[0052] Specifically, when the charging cable is in the charging state, the charging terminal 6 is energized to conduct the first electromagnet 53, and the first electromagnet 53 generates a magnetic attraction force on the driven member 52. The driven member 52 slides in the direction of the first electromagnet 53. During the sliding process of the driven member 52, through the cooperation of the first transmission structure and the second transmission structure, the rotating column 51 is driven to rotate clockwise, and the rotating column 51 synchronously drives the rotating disk 41 clockwise. At this time, under the cooperation of the switching member 45 and the arc groove 12, the first indicating unit 43 and the second indicating unit 44 are combined to form a charging form, as Figure 4 shown; similarly, when the charging cable is in the discharging state, the discharging terminal 7 conducts the second electromagnet 54, and the second electromagnet 54 generates a magnetic attraction force on the driven member 52. The driven member 52 slides in the direction of the second electromagnet 54, thereby driving the rotating column 51 to rotate counterclockwise, so that the first indicating unit 43 and the second indicating unit 44 are combined to form a discharging form, as Figure 5 shown; thus, during charging, through the magnetic attraction force of the first electromagnet 53 on the driven member 52, and during discharging, through the magnetic attraction force of the second electromagnet 54 on the driven member 52, the combined form of the first indicating unit 43 and the second indicating unit 44 is changed.

[0053] After being fully charged, the charging terminal 6 is de-energized, that is, the first electromagnet 53 is de-energized, and the torsion spring releases the stored energy, so that the first indicating unit 43 and the second indicating unit 44 are restored to the standby state, as Figure 3 shown. Similarly, after the discharging terminal 7 is de-energized, the second electromagnet 54 is de-energized, and the torsion spring releases the stored energy, so that the first indicating unit 43 and the second indicating unit 44 are restored to the standby state, as Figure 3 shown.

[0054] Through the cooperation among the first electromagnet 53, the second electromagnet 54, the driven member 52, and the rotating column 51 of this embodiment, the charging cable realizes the full-automatic form switching from charging, discharging, to standby, without the need for additional user operations, improving the intelligent interaction experience of the charging cable.

[0055] As Figure 6 shown, in some embodiments of the charging cable with a dynamic form-changing indicator of this embodiment, the first transmission structure is an incomplete gear ring 511; the second transmission structure is a rack 521 arranged along the length direction of the follower 52. The rack 521 meshes with the incomplete gear ring 511. With such a setting, when the follower 52 slides, the rack 521 and the incomplete gear ring 511 engage and drive, thereby driving the rotating column 51 to rotate, converting the linear motion of the follower 52 into the rotational motion of the rotating column 51.

[0056] As Figure 2 and Figure 11 shown, in some embodiments of the charging cable with a dynamic form-changing indicator of this embodiment, a second sliding groove 14 is provided in the first connector 1; the follower 52 is slidably arranged in the second sliding groove 14; the first electromagnet 53 and the second electromagnet 54 are arranged at both ends of the second sliding groove 14. By providing the second sliding groove 14 in this embodiment, it is convenient for the installation of the follower 52, the first electromagnet 53 and the second electromagnet 54.

[0057] As Figure 2 shown, in some embodiments of the charging cable with a dynamic form-changing indicator of this embodiment, accommodating grooves 11 are provided on two opposite surfaces of the first connector 1, and charge-discharge indication modules 4 are provided in both accommodating grooves 11; two rotating disks 41 are fixedly connected to both ends of the rotating column 51. With such a setting, the state of the charging cable can be displayed through the charge-discharge indication module 4 on both the front and back sides of the first connector 1, making the structure more convenient to use.

[0058] The above are only the preferred embodiments of the present invention. Therefore, any equivalent changes or modifications made according to the structures, features and principles described in the scope of this invention patent application are included in the protection scope of this invention patent application.
