DETAILED DESCRIPTION

[0035] The present application will be further described in detail below in conjunction with the drawings and specific embodiments, which are not intended to limit the scope of the present application.

[0036] As shown in the drawings, Figures 1 to 16 A protective charging wire with neck-hanging carrying function is designed to solve the problems of traditional charging wire storage, such as being complicated, easy to be damaged, and inconvenient to carry. The overall structure of the charging wire takes into account protection, convenient storage, and neck-hanging carrying function. The charging wire includes a wire body 1, which is the core carrier of power transmission and is made of high-flexibility wear-resistant material to meet the comfort requirements of repeated bending and neck-hanging. One end of the wire body 1 is provided with a first interface 2 and a first protection module 3, and the other end is provided with a second interface 4 and a second protection module 5. The first interface 2 can be provided with a USB-A interface and a Type-C interface, and the second interface 4 can be provided with a Type-C interface or a Lightning interface. The two interfaces are respectively used to connect power supply equipment and electrical equipment, and the two protection modules respectively play a protective role on the corresponding interfaces.

[0037] Specifically, as shown in the drawings, Figures 4 to 16As shown, the first protection module 3 and the second protection module 5 each include a protection seat 61; the protection seat 61 is fixedly sleeved at the end of the wire body 1, and provides a mounting base for other components of the entire protection module; the protection seat 61 is provided with a plurality of sliding block assemblies 62 distributed in the circumferential direction; the sliding block assemblies 62 are uniformly and circumferentially spaced apart, so as to ensure the balance of force; the plurality of sliding block assemblies 62 are jointly connected with a pressing ring 63; the pressing ring 63 can drive all the sliding block assemblies 62 to move synchronously; the protection seat 61 is jointly connected with the plurality of sliding block assemblies 62 on the side opposite to the first interface 2, and is jointly connected with a resilient reset member 64; the resilient reset member 64 provides power for the reset of the sliding block assemblies 62. Each sliding block assembly 62 is lockably connected with the protection seat 61, so as to realize the fixation of the sliding block assembly 62 at different positions. The other side of the protection seat 61 is provided with a connecting rod assembly 65 and an elastic shielding cover 66; the elastic shielding cover is made of a material with light weight, thin thickness, poor damageability and stretchability, such as thermoplastic polyurethane elastomer, ultra-high molecular weight polyethylene film, liquid silicone and the like; the elastic shielding cover has good stretchability and protection property, and is connected with the protection seat 61 at one end. The connecting rod assembly 65 is slidably connected with the protection seat 61 at one end and movably abuts against each sliding block assembly 62, and is connected with the inner wall of the elastic shielding cover 66 at the other end; the connecting rod assembly 65 can drive the elastic shielding cover 66 to switch states through movement; the elastic shielding cover 66 has a storage state and an unfolded state under the driving of the connecting rod assembly 65; in the storage state, the elastic shielding cover 66 is contracted, so that the first interface 2 or the second interface 4 is exposed, and the user can conveniently perform plugging and unplugging operations; in the unfolded state, the elastic shielding cover 66 is unfolded, and shields and protects the first interface 2 or the second interface 4, so as to reduce the influence of dust, moisture or collision damage on the interface.

[0038] In actual application, when the user needs to use the charging wire to charge, the pressing ring 63 is operated to drive the sliding block assembly 62 to move, so that the sliding block assembly 62 is unlocked from the protection seat 61; under the action of the resilient reset member 64, the sliding block assembly 62 is reset, and further drives the connecting rod assembly 65 to move, so that the elastic shielding cover 66 is switched from the unfolded state to the storage state, and the interface is exposed for connecting the equipment. After charging is completed, the pressing ring 63 is operated again, so that the sliding block assembly 62 is re-locked with the protection seat 61, and the connecting rod assembly 65 drives the elastic shielding cover 66 to switch from the storage state to the unfolded state, so as to protect the interface. When carrying is needed, the wire body 1 can be hung on the neck, as shown in the figure. Figure 3 As shown, since the wire body 1 is made of flexible material and the protection module structure is reasonably designed, the user will not feel obvious discomfort, and the function of hanging on the neck for carrying is realized.

[0039] As shown in the figure, Figures 3 to 16As shown, the protective charging line of the embodiment, the other end of the connecting rod assembly 65 of the first protection module 3 is provided with a first buckle structure; the other end of the connecting rod assembly 65 of the second protection module 5 is provided with a second buckle structure buckled with the first buckle structure; when the elastic shielding cover 66 is in the unfolded state, the first interface 2 and the second interface 4 are in the protection space surrounded by the two elastic shielding covers 66 through the buckling cooperation of the first buckle structure and the second buckle structure. Through the above-mentioned setting of the embodiment, the direct friction between the interface and the outside during carrying is reduced, which is beneficial to prolong the service life and further enhances the protection effect of the interface; the connection of the connecting rod assembly 65 between the two protection modules makes the charging line form a circular structure, as shown in Figure 3 Thus, it is not easy to fall off from the user's neck during carrying, and the carrying is more reliable, and at the same time, the wire body 1 can be kept in a regular state, avoiding the knotting of the wire caused by random winding.

[0040] Through the setting of the protection module at both ends of the charging line, the elastic shielding cover 66 can shield the interface in the unfolded state through the extrusion of the compression ring 63 and the movement of the sliding block assembly 62 and the connecting rod assembly 65, and the interface is in the protection space surrounded by the elastic shielding cover 66 through the cooperation of the first buckle structure and the second buckle structure, effectively avoiding the direct friction between the interface and the outside during carrying or idling and the contamination of foreign matters, which is beneficial to prolong the service life and enhance the protection effect of the interface, and the hanging-neck carrying is more reliable; in the storage state, the interface is directly exposed for use, and the operation is convenient.

[0041] As shown in Figure 6 , Figure 8 , Figure 11 , Figure 13 , Figure 15 and Figure 16 As shown, the protective charging line of the embodiment, in some embodiments, the sliding block assembly 62 includes a limiting sliding block 621; the limiting sliding block 621 is elastically and floatingly provided with a clamping pin 622 at one end; the bottom surface of the other end of the limiting sliding block 621 is provided with an inclined surface 623; the inclined surface 623 is outwardly and upwardly inclined from the center of the protection seat 61, and the setting of the inclined surface 623 provides a basis for cooperation with the connecting rod assembly 65; the protection seat 61 includes a protection disc body 611; the protection disc body 611 is protrudingly provided with an axle table 612 at one side, and the axle table 612 is integrally formed with the protection disc body 611 to ensure the stability of the structure; the outer side wall of the axle table 612 is provided with a locking groove corresponding to each limiting sliding block 621; the clamping pin 622 is movably embedded in the corresponding locking groove, and the cooperation of the clamping pin 622 and the locking groove realizes the locking and unlocking of the sliding block assembly 62 and the protection seat 61.

[0042] As shown in Figure 15As shown, the protective charging cord of the embodiment, in some embodiments, the locking groove includes a straight groove 6131, a first inclined groove 6132 and a second inclined groove 6133, one end of the straight groove 6131 is connected with one end of the first inclined groove 6132, the other end of the first inclined groove 6132 is connected with one end of the second inclined groove 6133, and the other end of the second inclined groove 6133 is connected with the other end of the straight groove 6131, forming a closed groove structure. A locking step 6134 is arranged between one end of the straight groove 6131 and one end of the first inclined groove 6132, which makes the catch 622 be locked by the elastic restoring member 64 when sliding from the straight groove 6131 into the first inclined groove 6132 without external force, so that the elastic shielding cover 66 is kept in the current state under the action of the linkage assembly 65. A blocking step 6135 is arranged between the other end of the first inclined groove 6132 and one end of the second inclined groove 6133, which is used to limit the sliding range of the catch 622 from the second inclined groove 6133 into the first inclined groove 6132. A transition slope 6136 is arranged in the second inclined groove 6133, which enables the catch 622 to slide smoothly in the second inclined groove 6133. Initially, the catch 622 is located in one end of the straight groove 6131 away from the locking step 6134 under the action of the elastic restoring member 64.

[0043] As shown in Figure 5 , Figure 6 , Figure 8 , Figure 11 , Figure 13 and Figure 15 As shown, the protective charging cord of the embodiment, in some embodiments, the elastic restoring member 64 is a spring; the spring is sleeved on the outer periphery of the shaft table 612; one end of the spring abuts against the protective disc body 611, and the other end of the spring movably abuts against each limiting sliding block 621. Specifically, when the sliding block assembly 62 is subjected to the pressure of the pressure ring 63, the spring is compressed to store elastic potential energy; when the pressure is released, the spring releases the elastic potential energy to reset the sliding block assembly 62.

[0044] As shown in Figure 9 and Figure 14As shown, in some embodiments, the protective charging cable of the present embodiment includes a plurality of first connecting members 651 and a plurality of second connecting members 652. The plurality of first connecting members 651 are distributed circumferentially and are respectively connected to the protective disc body 611 in a radial sliding manner, so as to ensure that the first connecting members 651 can slide freely along the radial direction of the protective disc body 611. The plurality of second connecting members 652 are distributed circumferentially and are respectively fixedly bonded to the inner wall of the elastic shielding cover 66, and the connection is firm. The plurality of second connecting members 652 are arranged in one-to-one correspondence with the plurality of first connecting members 651. Each second connecting member 652 is hingedly connected with two adjacent first connecting members 651 via a connecting rod member 653. The connecting rod member 653 hingedly connected with the second connecting member 652 is hingedly connected with the connecting rod member 653 hingedly connected with the adjacent second connecting member 652 in an "X" shape. Such an "X" shape hinged structure makes the connecting rod assembly 65 more stable when moving, and can smoothly drive the elastic shielding cover 66 to expand or contract. The second connecting member 652 of the first protective module 3 is provided with a first buckle structure, and the second connecting member 652 of the second protective module 5 is provided with a second buckle structure.

The second buckle structure is a clamping hole 681 provided in the second connecting member 652 and a clamping groove 682 provided on the hole wall of the clamping hole 681. When the elastic buckle 67 is inserted into the clamping hole 681, the barb structure is clamped into the clamping groove 682, so as to realize the stable cooperation of the first buckle structure and the second buckle structure. When it is necessary to separate, only the two protective modules need to be pulled with force, the elastic buckle 67 is deformed, the barb structure is separated from the clamping groove 682, and the separation can be realized.

[0046] As shown in Figure 6 , Figure 8 , Figure 11 and Figure 13 , in some embodiments, the protective charging cable of the present embodiment, the first connecting member 651 is provided with a top pin 6511; the end of the top pin 6511 penetrates through the protective disc body 611 and is in movable abutment with the corresponding inclined surface 623. Through the above arrangement, when the slider assembly 62 moves, the inclined surface 623 pushes the top pin 6511 to move, thereby driving the first connecting member 651 to slide in the radial direction, and realizing the linkage of the connecting rod assembly 65.

[0047] As shown in Figures 4 to 15As shown, the protective charging wire of the embodiment, in some embodiments, the outer wall of the top pin 6511 is provided with a sliding table 6512; the protective disc body 611 is radially provided with a sliding hole 614 corresponding to each first connecting piece 651; the top pin 6511 is movably penetrated through the sliding hole 614; and the sliding table 6512 is slidingly connected in the sliding hole 614. Through the above setting, the cooperation of the sliding table 6512 and the sliding hole 614 plays a guiding and limiting role on the movement of the top pin 6511, so as to ensure that the top pin 6511 can stably slide in the radial direction, and avoid that the top pin 6511 deviates to affect the normal work of the connecting rod assembly 65.
