Fig. 1 is a schematic view of a wire harness structure according to an embodiment of the present invention, in which a wire harness is in an expanded state, wires 1 in the drawing extend in an expanded direction, and a part of the wires 1 in the drawing is deleted for convenience of illustration, so that the wires 1 do not correspond to the number of connection terminals of a wire harness one by one. Fig. 2-4 show the different states of the wire, respectively, the wire in both figures also being in the deployed state. The dash-dot line in fig. 5 is the outer contour of the wire. The upper left view is the unfolded state of the wire rod from the direction B in fig. 1, and the plurality of wires 1 in the unfolded state are on the same plane, namely, the plurality of wires 1 have a straight outline. The upper right view is a folded state of the wire rod viewed from the B direction in fig. 1, that is, the plurality of wires 1 have a U-shaped profile, the lower view is a wire rod viewed from the shaft side, and the plurality of wires in the lower view are arranged in the height direction. In the upper right and lower drawings, A3 is a bending plane A3 of the wire rod when bending, that is, the bending plane A3 is located in the thickness direction of the wire rod. In fig. 5, A1 is a bending section of the wire, and it can be seen that when the wire harness is bent, only the bending section A1 generates a certain curl along the bending plane A3, while the rest is still in a straightened state.

As shown in fig. 1 to 5, the wire in the present embodiment includes a plurality of wires 1, the plurality of wires 1 are arranged in parallel, the wires 1 have bending sections A1, and the bending section A1 of each wire 1 includes at least one bending section 11, and the bending section 11 is bent in the arrangement direction toward or away from the wires 1 to have a degree of freedom of extension in the arrangement direction of the wires 1. The bending section 11 is configured such that when the wire is folded, the bending section A1 deforms in the circumferential direction of the arrangement direction of the wires 1, and generates a tensile force that stretches the bending section 11 to compensate for the varying length of at least part of the wires 1.

The tensile force in this embodiment is shown by arrow C2 in fig. 2 and 5, and extends along the wire's trend. C1 in fig. 2 and 5 is the deformation direction of the bending section under the tensile force. In the two figures, C1 and C2 are in a vertical or substantially vertical direction, and in the example of fig. 2, the two groups of wires 1 are bent in the upward and downward directions, respectively, so that a space area A4 is present in the middle of the two. Under the action of the tensile force, the bent sections 11 in both the up and down directions are simultaneously stretched toward the space area A4, so that the length of the wire 1 in the horizontal direction is increased. This increased length may compensate for the increased length of the wire when the wire is bent, particularly when the wire is bent along with the hinge assembly.

It will be readily appreciated that, for example, in a folding screen handset, there are provided first and second electronic components and a hinge assembly, the first and second electronic components being secured to two rotating parts of the hinge assembly, respectively, which are rotatably connected by a main shaft of the hinge assembly. When the lead 1 is connected to the first electronic component and the second electronic component, the two ends of the lead 1 are connected to the first electronic component and the second electronic component respectively through the wiring rows. The bending section A1 of the wire 1 is located at or substantially at the main axis of the hinge assembly. The distance between the first electronic component and the second electronic component is shorter when the mobile phone is in the unfolded state. When the mobile phone is in a folded state, a distance which is approximately the same as an arc line on the side wall of the main shaft is increased between the first electronic element and the second electronic element, so that a stretching force is generated on the wire harness positioned between the first electronic element and the second electronic element. This tensile force will be concentrated in the folded position of the hinge, i.e. the spindle position. For this reason, the bending section A1 in the present embodiment is disposed near the main axis of the hinge assembly, so as to generate deformation at the concentrated position of the pulling force, and compensate the length variation of the wire 1 to the maximum.

The wire according to the embodiment of the present invention utilizes the degree of freedom of extension that the bent section 11 of the wire has, so that the wire has the capability of changing in the length direction. Thereby, when the wire is placed inside the electronic device, the bent section 11 can be unfolded in the folded state of the electronic device, thereby compensating for the dimensional change in the length direction of the wire 1. The bending section 11 can also bend in opposite directions when the electronic device is in the unfolded state, so that the redundant length of the wire1 is effectively stored, and the space occupation of the electronic device is reduced.

Optionally, the number of bending sections 11 or the bending amplitude (the blank area A4) of any wire 1 may be selected according to the bending angle or the bending radius of the electronic device. For example, when the bending radius is large, the bending width of the bending section 11 and the number of bending sections can be increased, thereby allowing a larger length deformation amount on the bending section A1.

In some embodiments, as shown in fig. 1-5, the plurality of wires 1 includes a first wire set 113, and the plurality of bent segments 11 form a first segment set 111, where each bent segment 11 of the first segment set 111 corresponds to each wire of the first wire set 113 one-to-one. Each of the bent segments 11 in the first segment group 111 is simultaneously bent in the arrangement direction toward or away from the wires 1 and arranged in the arrangement direction of the wires 1. In this embodiment, the directions and positions of the plurality of bending sections 11 are further configured, so that the plurality of bending sections 11 are all bent in the same direction, and the arrangement directions of the bending sections 11 are the same, so that the arrangement space of the wires 1 is greatly reduced.

Alternatively, a different form of curved section 11 is shown in fig. 3. In state ii, the same wire 1 has 2 bending sections 11, and both bending sections 11 are bent upward at the same time, and the connection point of both bending sections 11 also has an arc-shaped region. In this embodiment, the bending amplitude of each bending section 11 is the same, and the hollow areas of two adjacent bending sections 11 overlap each other, so that the arrangement of the plurality of wires 1 is more regular, and the plurality of wires 1 can be simultaneously bent or stretched towards the same direction when being bent, so as to avoid interference between each other.

In other embodiments, as shown in fig. 1-5, the plurality of curved segments 11 further form a second segment set 112, each curved segment 11 of the second segment set 112 being in one-to-one correspondence with each wire of the first wire set 113. The bending direction of each bending section 11 in the second section group 112 is opposite to the first section group 111 and is aligned along the alignment direction of the wire 1. In the state iii of fig. 3 and in the state vii of fig. 4, the same wire has 2 bent sections 11, but the two bent sections 11 are bent upward and downward, respectively. The wire 1 in the middle area of the two bending sections 11 can be kept in a straight line or a nearly straight line state when the wire bundle is in a folded state or an extended state, so that the service life of the wire 1 in the area is prolonged.

In some embodiments, as shown in fig. 1-5, the plurality of wires 1 further includes a second wire set 114, and the plurality of bent segments 11 further form a second segment set 112, where each bent segment 11 of the second segment set 112 corresponds to each wire of the second wire set 114 one by one, and the bending direction of the second segment set 112 is opposite to the first segment set 111 and is aligned along the alignment direction of the wires 1. The second segment group 112 in this embodiment is on a different wire 1 than the first segment group 111 and is bent in the opposite direction. Fig. 3 shows a configuration of the first segment set 111 and the second segment set 112 in this embodiment, in which there are 2 bent segments 11 per wire. The first and second segment groups 111 and 112 are simultaneously extended inward when the wire harness is folded, and the first and second segment groups 111 and 112 are also simultaneously bent to both sides when the wire harness is unfolded. In this embodiment, the bending sections 11 with opposite directions are utilized, so that the stress of the wires in the arrangement direction can be balanced when the whole bending section A1 is bent or unfolded, and the bending section A1 is prevented from shaking during deformation, that is, the first wire set 113 and the second wire set 114 are inconvenient to position in the arrangement direction when the state i is bent.

Further, the positions of the first segment group 111 and the second segment group 112 correspond to each other. The positions of the first segment group 111 and the second segment group 112 are arranged to coincide in the extending direction of the wire 1 in this embodiment. Thereby making the arrangement of the wire harness more orderly. Preferably, the number of wires 1 of the first wire group 113 and the second wire group 114 is configured to be the same, so that the first wire group 113 and the second wire group 114 are largely symmetrical to each other.

In some embodiments, as shown in fig. 1-5, each curved segment 11 includes two straight segments 115 and a first arc segment 116 connecting the two straight segments 115, the first arc segment 116 having the same opening angle at each curved segment 11. The first arc segment 116 in this embodiment is located between the two straight segments and is deformed at the first arc segment location as the curved segment bends and stretches. Thus, the first arc segment provided in this embodiment may provide deformation for bending, and the straight line segment provided may increase the magnitude of bending. As shown in state iv of fig. 4, the included angle α of the two curved segments on the wire shown in the figure is the same. When deformation occurs, the same deformation amount can be generated to two sides at the same time, so that the position of the bending section is more stable.

In some embodiments, as shown in fig. 1-5, the bending section A1 further includes a second arc segment 117, and two adjacent bending segments 11 with the same bending direction are connected to the second arc segment 117 through a straight line segment 115, and the opening angle of the second arc segment 117 is the same as the opening angle of the first arc segment 116. As shown in state vi of fig. 4, two curved sections 11 on the wire 1 shown in the figure are arranged adjacently, which are connected by a second arc section 117. An extension 118 is provided between the two curved sections 11 shown in states iv and v, in which case the two curved sections 11 are not adjacent. In contrast, in the present embodiment, the two curved sections 11 are disposed adjacently, so that the first arc section 116 and the second arc section 117 can be deformed simultaneously when deformed. Specifically, the included angle α of the first arc segment 116 and the included angle β of the second arc segment 117 in the drawing are set to be the same, that is, a wavy line is formed by the first arc segment 116, the second arc segment 117, and the straight line segment 115 together in the bending section A1. Thereby, the deformation amplitude is further improved, and the deformation amplitude of the first arc segment 116 and the second arc segment 117 is made the same.

In some embodiments, as shown in fig. 1-5, the plurality of wires 1 have a first extension a21 and a second extension a22 located at both ends of the bending section A1. The wire harness structure further includes a first wire row 21 and a second wire row 22, the number of wire terminals of the first wire row 21 and the second wire row 22 being the same as the number of the plurality of wires 1, and being connected to the first extension section a21 and the second extension section a22, respectively. The first extension section a21 and the second extension section a22 in the present embodiment may be provided at two rotational member positions of the hinge. Thus, the two sections may not deform when the electronic device is folded, but follow the two rotating members together.

The wire in the above embodiment may be applied to a hinge assembly, in an alternative implementation manner, the hinge assembly further includes a main shaft and two rotating parts rotatably connected through the main shaft, an arrangement direction of the plurality of wires 1 in the wire is consistent with an extension direction of the main shaft, two ends of the plurality of wires 1 of the wire are respectively electrically connected with the two rotating parts, and a bending section A1 of the wire is located at a position of the main shaft. The bending amplitude of the bending sections 11 in the bending section A1 on the wire and the number of bending sections 11 are related to the radius of rotation and the folding angle of the hinge assembly, for example, when the radius of rotation is large or the folding angle is 180 °, the number of bending sections 11 and the bending angle of the bending sections 11 can be increased on the same wire 1, thereby increasing the length compensation of the wire 1.

The hinge assembly of the embodiment of the present invention utilizes the degree of freedom of extension that the curved section 11 has, so that the wire has the ability to vary in the length direction. Thereby, the bent section 11 can be unfolded in the folded state of the electronic device, thereby compensating for the dimensional change in the length direction of the wire 1. The bending section 11 can also bend in opposite directions when the electronic device is in the unfolded state, so that the redundant length of the wire 1 is effectively stored, and the space occupation of the electronic device is reduced.

The hinge assembly in the above embodiment may be applied to an electronic device, and in an alternative implementation, the electronic device may be a mobile phone, a notebook computer, a smart watch, or the like. The hinge assembly can be used for realizing folding functions on a mobile phone or a notebook computer, such as folding functions of a flexible screen mobile phone, folding functions of the notebook computer and the like.

The electronic device of the embodiment of the invention utilizes the degree of freedom of extension of the bent section 11, so that the wire has the capability of changing in the length direction. Thereby, the bent section 11 can be unfolded in the folded state of the electronic device, thereby compensating for the dimensional change in the length direction of the wire 1. The bending section 11 can also bend in opposite directions when the electronic device is in the unfolded state, so that the redundant length of the wire 1 is effectively stored, and the space occupation of the electronic device is reduced.

It is easy to understand that, as shown in fig. 7, the curved groove 321 in the present embodiment is adapted to the shape of the curved section 11 of the wire 1 in the above embodiment, so that when the wire 1 in a straight state is inserted into the groove along the curved groove 321, the wire 1 can be curved along the curved groove 321, thereby forming the curved section 11.

Specifically, the bent section 11 of the wire 1 is connected with an extension section 118. In contrast, the curved groove 321 of the wire groove 32 is also connected with the extension groove 322. After the first wire row 21 is fixed to the wire row groove 31, the wire 1 to be processed is first arranged along the extension groove 322 and then arranged in the bending direction at the position of the bending groove 321. Finally, the tail end of the wire 1 is extended into the extension groove 322 located at the other side of the bending groove 321.

Step S400: the second terminal block 22 is connected to the tail ends of the plurality of wires 1.

In this embodiment, the shape of the wire 1 is fixed in the wire slot 32, and then connected with the second wire connection row 22, so that the shape of the final finished wire harness is more stable, and the processing speed is improved. That is, in this embodiment, the processing of the wire harness is sequentially completed through the first wire row 21, the extension section 118, the bending section 11, the other extension section 118 and the second wire row 22, so that the problems that the generated wire 1 is not easy to bend and deform, and cannot be well adapted to the wire slot 32 after the length change when the wire 1 is bent after the first wire row 21 and the second wire row 22 are fixed at the two ends of the wire 1 are avoided.

Alternatively, in order to allow the wire harness to be processed to be adapted to different forms of the bent section 11, the wire 1 of the wire harness to be processed may be set longer or slightly longer than the length of the wire 1 of the finished wire harness, after the wire 1 is arranged in the wire groove 32, the surplus length may be cut according to the size of the finished wire harness of the present lot, and the cut tail end may be stripped of the insulation, and then the second wire harness 22 may be connected. Thus, when the finished wire harnesses of different forms or different lengths need to be processed simultaneously, the length of the wire harness to be processed can be configured to be adaptable to the finished wire harnesses of different forms by cutting under the condition that the number of wires is the same.

Further, before connecting the second wire row 22 with the tail ends of the plurality of wires 1, attaching a release paper 4 to the tail ends of the plurality of wires 1, and removing the wire harness to be processed from the first carrier 3. Then, the wire harness to be processed is reversed, and the insulating layer at the tail end of the wire is removed by laser, so that the wire cores of the plurality of wires 1 are exposed. As shown in fig. 6 and 8, the tail end of the wire does not protrude from the wire chase after the wire is inserted into the wire chase. Specifically, in this embodiment, the release paper 4 may be tissue paper, and the tissue paper is used to attach to the tail end of the wire 1. In the peeling stage of the wire 1, the laser is further utilized, and in order to facilitate the peeling operation, the person skilled in the art can take the wire harness to be processed together with the tissue paper off the first carrying platform 3 and then reverse the wire harness so that the tissue paper is located below the wire 1, and the tissue paper mainly plays a role in fixing the wire 1 in the process. When the laser burns the tail end of the wire (dashed box in state viii of fig. 8), the laser intensity may be configured to burn the tissue paper along with the insulating sheath. As shown in fig. 8, the operator can remove the peel along with the tissue to obtain a more complete area of the wire (shown in fig. 8 at ix), the exposed area, i.e., the core. The embodiment uses laser to burn the tail end of the wire rod and simultaneously matches with the fixation of cotton paper, thereby simplifying the operation procedure.

Optionally, as shown in fig. 7, a clamping groove 33 is further provided in the extending direction of the wire groove 32 of the first carrier 3, the clamping groove 33 is used for providing the guiding block 8, and the wire groove 32 corresponding to the tail end of the wire 1 is located in the area. In the above embodiment, in the reversing stage of the wire harness to be processed, the guide block 8, the tissue paper, and the wire harness to be processed which is clamped by the guide block 8 and the tissue paper together can be taken from the first stage 3 and then reversed together, and the guide block 8 is taken from the tissue paper after being reversed so as to expose the tail end of the wire 1. This way, it is ensured that the wire harness to be processed remains regular when it is removed from the first carrier 3, thus preparing for subsequent laser firing.

So that the finished wire in the final wire assembly is located in the middle region of the first stationary film 51. On the other hand, the second fixing film 52 is attached to the first fixing film 51, and is attached to the wire 1 of the final wire rod by the attachment region 521.
