Description

Technical Field

[0001] This utility model relates to a bending control component and a power supply device, belonging to the fields of vehicle accessories and power supply. Background Technology

[0002] In the automotive industry, sliding door systems are increasingly favored by customers due to their unique opening mechanism and numerous advantages over traditional hinged revolving doors. For example, side-sliding door designs are commonly used in luxury MPVs, and even more and more five-seater vehicles are adopting this design. Electric sliding door technology requires a continuous, stable, and safe power supply system for transmitting current and signals between the sliding door and the vehicle body. The bending control component within the power supply system is indispensable for ensuring the sliding door's movement, playing a crucial role in trajectory control and increasing strength.

[0003] Traditionally, bending control components consist of a flat plate and several unit sections. When the unit sections are in a snap-fit ​​state, they interlock in a straight line or arrow shape, providing support and trajectory control.

[0004] However, during the sliding door's movement from fully open to fully closed, the bending shape of the power supply device changes accordingly, thus subjecting it to various bending deformation forces. Traditional power supply devices lack effective technology to control the displacement caused by these forces in their bending control components, making it easy for the flat portion of the bending control component to twist. This can lead to failures such as wire clamping, deformation, or even breakage. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a bending control component and a safe, stable, and continuous power supply device incorporating the bending control component. This effectively controls the degrees of freedom in each direction of the unit sections within the bending control component, making the interlocking of the unit sections more reliable and preventing misalignment. Even when the power supply device is subjected to force during bending, it can suppress misalignment between unit sections to a certain extent, thereby inhibiting torsion of the flat portion of the bending control component. This prevents failures such as wire clamping, deformation, and breakage of the bending control component, effectively reducing the occurrence of adverse situations such as the inability to open and close the car door normally and circuit malfunctions due to the failure of the bending control component.

[0006] Specifically, the first aspect of this utility model provides a bending control component for controlling the bending of a wiring harness laid from the vehicle body to a sliding door, the bending control component comprising:

[0007] The assembly includes multiple unit segments arranged along the length of the wire harness; and a flexible flat plate portion that connects adjacent unit segments to each other, allowing adjacent unit segments to engage with each other to control the bending of the flat plate portion in a predetermined direction.

[0008] The unit segment includes a protrusion and a receiving portion disposed along the length direction. The protrusion of one unit segment can engage with the receiving portion of an adjacent unit segment, such that in this engaged state, the protrusion and the receiving portion restrict displacement between unit segments in the width direction of the flat plate portion.

[0009] The protrusion of the unit section is formed in an inclined shape as it extends protruding in the length direction, and the receiving portion of the unit section is formed in a shape that matches the corresponding protrusion.

[0010] Based on the bending control component with the above-described structure, the bending shape of the wiring harness from the vehicle body to the sliding door can be precisely managed and controlled. This ensures that the wiring harness maintains necessary flexibility during movement while avoiding damage or performance degradation caused by excessive bending. By designing a protrusion and a receiving portion for each unit section, the protrusion can engage with the receiving portion of an adjacent unit section, while the receiving portion can receive the protrusion of another adjacent unit section. This simple structural design, through the interlocking cooperation between unit sections, restricts the degree of freedom of movement of each unit section under bending stress, thus limiting displacement between unit sections, at least in the width direction. This prevents accidental torsional deformation of the flat section and avoids failures such as wire clamping, deformation, and breakage of the bending control component, ensuring the stability of the wiring harness during bending. Furthermore, the protrusion extends protrudingly and tilts along its length, making the engagement process smoother and reducing wear and noise caused by friction or collision. The tilted shape also increases the contact area and friction between the protrusion and the receiving portion, further improving the stability and durability of the engagement.

[0011] Preferably, in the bending control component having the above structure, the protrusion of the unit section is formed as an inclined tooth protruding from one end face in the length direction of the unit section, such that at least one of the two sides of the protrusion in the width direction is an inclined surface, so that the two sides gradually approach each other as they move away from the one end face, and the receiving portion of the unit section is formed as a recessed portion recessed from the other end face in the length direction of the unit section.

[0012] According to the bending control component with the above structure, the protrusion is designed as an inclined tooth protruding from one end face in the length direction of the unit segment. This allows the protrusion to not only provide a biting point in the length direction but also to generate a constraint effect in the width direction through its inclined shape. This enables the control of the unit segment's degrees of freedom in both the length and width directions, suppressing displacement between unit segments in both directions. Since at least one of the two sides of the protrusion in the width direction is an inclined surface, the two sides gradually approach each other as they move away from one end face. Furthermore, the side of the mating receiving portion is also formed into a matching shape, i.e., an inclined surface. Therefore, when the protrusion of one unit segment bites into the receiving portion of an adjacent unit segment, the biting process is smoother, reducing wear and noise caused by friction or collision. Moreover, when the biting is completed, it can be regarded as forming a "wedge" structure, enhancing the stability and reliability of the biting.

[0013] Preferably, in the bending control component having the above structure, the inclined surface of the protrusion of the unit section is inclined at an angle of 8 to 12 degrees relative to the length direction.

[0014] According to the bending control component with the above structure, the inclined surface of the protrusion of the unit section is inclined at an angle of 8 to 12 degrees relative to the length direction, which can achieve a balance between stability and flexibility. This not only helps to improve the performance and effectiveness of the bending control component, but also ensures that the wire harness maintains its predetermined shape and performance during bending. Within this angle range, the inclined surface of the protrusion and the mating shape of the receiving part can fit tightly together to form an effective engagement. This tightness helps to reduce displacement or disengagement caused by external forces. At the same time, this range of inclination angles can reduce friction and collision during engagement, thereby reducing wear and noise generation, and improving both the durability of the component and user comfort.

[0015] Preferably, in the bending control component having the above structure, the end face of the protrusion is an inclined surface that is inclined at an angle of 2 to 5 degrees relative to the height direction.

[0016] According to the bending control component with the above structure, the end face of the protrusion of each unit section is designed to be inclined at an angle of 2 to 5 degrees relative to the height direction, so that the protrusion length of the protrusion gradually increases as it gets closer to the flat plate side. Utilizing this inclined end face configuration, when the bending control component bends towards the opposite side of the flat plate, and thus the protrusion of one unit section needs to be inserted into the recess of an adjacent unit section for bending restriction, the slightly longer inner end of the protrusion closer to the flat plate side will first contact the corresponding recess, thereby providing alignment guidance and preventing slippage.

[0017] Preferably, in the bending control component having the above structure, the protrusion of the unit segment may be formed as a frustum protruding from one end face of the unit segment in the length direction, such that when viewed from the width direction, the end face of the frustum is inclined in an arc shape, and the receiving portion of the unit segment is formed as a recessed portion recessed from the other end face of the unit segment in the length direction.

[0018] According to the bending control component with the above structure, the protrusion of the unit section is designed in the shape of a frustum, so that the end face of the part that engages with the corresponding receiving part is inclined in an arc shape. Therefore, the engagement between the protrusion and the receiving part becomes a receiving engagement between an arc-shaped protrusion and an arc-shaped concave part. This arc-shaped inclination provides a smooth transition and contact surface, ensuring that the protrusion can be smoothly inserted and guided into the receiving part and form a good fit. The degree of freedom of the unit section is controlled in the length, height, and width directions. Moreover, the frustum design increases the contact area between the protrusion and the receiving part, which helps to distribute contact pressure, improve the stability and durability of the connection, and the arc-shaped inclined surface makes the stress distribution more uniform, reducing the risk of damage caused by stress concentration.

[0019] Preferably, in the bending control component having the above structure, one end face of the unit segment is parallel to the other end face, and the arcuate chord constituting the recess is inclined at an angle of 2 to 5 degrees relative to the other end face.

[0020] According to the bending control component with the above structure, the arcuate chord constituting the recess of each unit segment is not aligned with the other end face but is inclined at an angle of 2 to 5 degrees, such that the arcuate chord constituting the recess moves further away from the other end face as it moves away from the flat plate side. Therefore, when the bending control component bends towards the opposite side of the flat plate so that the protrusion of one unit segment is to be inserted into the recess of the adjacent unit segment for bending restriction, the arcuate protrusion and the arcuate recess first come into contact with each other on the side closer to the flat plate, thereby providing guidance and alignment and preventing slippage.

[0021] Preferably, in the bending control component having the above structure, the unit segment may be formed to include a first part and a second part integral in the width direction. In the upper part of the unit segment in the height direction, the first part is offset relative to the second part in the length direction, such that in the length direction, one end of the first part protrudes relative to the second part to form a first protrusion, and the other end of the first part is recessed relative to the second part to form a first recess. In the lower part of the unit segment in the height direction, the first part is offset relative to the second part in the length direction in the opposite direction to that in the upper part, such that in the length direction, one end of the first part is recessed relative to the second part to form a second recess, and the other end of the first part protrudes relative to the second part to form a second protrusion.

[0022] According to the bending control component with the above structure, the first part of the unit section is formed into a Z-shaped structure with staggered vertical alignment, and the second part is a rectangle with consistent vertical alignment. Thus, relative to the second part, one end of the upper length direction of the first part protrudes while the other end is recessed, and one end of the lower length direction of the first part is recessed while the other end protrudes. Therefore, the unit sections interlock in a Z-shape. During the bending of the flat plate, this Z-shaped interlocking between adjacent unit sections controls the degrees of freedom of the unit section in the length, height, and width directions of the flat plate, providing stable support in multiple directions and reducing swaying and displacement of the wire harness during movement.

[0023] Preferably, in the bending control component having the above structure, the surfaces of the first protrusion and / or the second protrusion for engaging with adjacent unit sections in the height direction are inclined surfaces.

[0024] According to the bending control component with the above structure, the surfaces of the first protrusion and / or the second protrusion for engaging with adjacent unit sections in the height direction are designed as inclined surfaces, so that the protrusion and the recess of the adjacent unit section can form a more stable contact relationship when engaged. The inclined surfaces can guide and lock the protrusion, preventing it from accidentally sliding or disengaging during movement. Moreover, the inclined surfaces help to distribute the force at the engagement point, reducing stress concentration, which not only improves the durability of the engagement part, but also reduces the risk of damage caused by uneven force. In addition, the inclined surfaces can generate a certain guiding effect during the engagement process, reducing wear caused by friction.

[0025] Preferably, in the bending control component having the above structure, the inclined surface of the first protrusion and / or the second protrusion is inclined at an angle of 2 to 5 degrees relative to the length direction.

[0026] According to the bending control component with the above structure, the inclined surfaces of the first protrusion and / or the second protrusion are inclined at an angle of 2 to 5 degrees relative to the length direction. This allows the mating inclined surfaces to better fit together and form a stable contact relationship when adjacent unit sections come into contact with each other. When the unit section is subjected to external force during bending, the inclined surfaces provide additional support and restraint, and also help to distribute pressure between unit sections, avoiding damage caused by excessive force at a single point. Moreover, the design of this inclined angle allows adjacent unit sections to engage more smoothly during the process of straightening the flat section from bending.

[0027] A second aspect of this utility model provides a power supply device disposed in a vehicle having a body and a sliding door and electrically connecting the body and the sliding door, the power supply device comprising:

[0028] Wiring harness, which is arranged between the vehicle body and the sliding door; and

[0029] A bending control component arranged along the harness as described in the first aspect.

[0030] According to the power supply device of the second aspect, since it includes a bending control component as described in the first aspect arranged along the wire harness, it is possible to achieve the same technical effect as described in the first aspect. Attached Figure Description

[0078] The technical solution of the present invention will be explained more clearly below by referring to the accompanying drawings and describing specific embodiments of the present invention.

[0079] It should be noted that the accompanying drawings of this utility model are merely schematic diagrams for clearly illustrating the parts related to the solution of this utility model, and do not show some unnecessary parts. Therefore, these drawings should not be construed as limiting the utility model, and may differ from the actual structure in use. Furthermore, it should be understood that terms indicating orientation or position such as "up," "down," "left," "right," "front," and "rear" that may appear in the following description are for convenience of explanation and not restrictive. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0080] The following will describe a bending control component and a power supply device according to an embodiment of the present invention.

[0081] Figure 1This is a view showing a power supply device for a bending control component applied according to an embodiment of the present invention. The power supply device 1 of this embodiment is installed in a vehicle 5. The power supply device 1 is a device for supplying power via a wiring harness 110 from a power source (not shown) located on the side of the vehicle body 60 to an electronic device (not shown) located at the sliding door 50. Furthermore, in Figure 1 In the diagram, the right side corresponds to the front of vehicle 5, the left side corresponds to the rear of vehicle 5, the top corresponds to the outer side of vehicle 5, and the bottom corresponds to the inner side of vehicle 5. Furthermore, the X direction in the diagram represents the left-right direction of vehicle 5, the Y direction represents the front-back direction of vehicle 5, and the Z direction represents the up-down direction of vehicle 5.

[0082] The power supply unit 1 includes a wiring harness 110, a corrugated tube 120, a bending control component 130, a door-side retaining part 140, and a body-side retaining part 150. The wiring harness 110 is constructed by bundling multiple wires 111 together, and the portion of the wiring harness 110 between the body 60 and the sliding door 50 is inserted into the corrugated tube 120, which is a flexible tube made of resin.

[0083] The wire 111 is not only a power line for supplying electricity, but may also include signal lines for sending and receiving signals between a control device (not shown) disposed on the vehicle body 60 and an electrical device (not shown) disposed on the sliding door 50. The bending control component 130 is arranged along the wire harness 110, so that it is circumferentially surrounded between the inner surface of the bellows 120 and the wire harness 110. The bending control component 130 will be described in detail later.

[0084] One end of the bellows 120 on the sliding door 50 side is pivotally held in the door-side retaining part 140 in the XY plane around the door-side rocking axis 141 along the Z direction. The door-side retaining part 140 is fixed in the sliding door 50. The door-side rocking axis 141 arranged on the door-side retaining part 140 is an axis parallel to the sliding door 50 and perpendicular to the opening and closing direction D11 of the sliding door 50 (the Y direction is the front-to-back direction).

[0085] Since the bellows 120 is held by the door-side retaining portion 140, a portion of the wiring harness 110 on the sliding door 50 side is pivotally held in the XY plane around the door-side rocking axis 141. The wiring harness 110 on the sliding door 50 side protrudes from one end of the bellows 120 on the sliding door 50 side. Furthermore, the wiring harness 110 protrudes from the door-side retaining portion 140 through an internal channel (not shown) of the door-side retaining portion 140 and then extends to the electrical components of the sliding door 50.

[0086] On the other hand, one end of the bellows 120 at the vehicle body 60 is pivotally held in the vehicle body side retaining part 150 in the XY plane around the vehicle body side rocking axis 151 along the Z direction. The vehicle body side retaining part 150 is fixed in the vehicle body 60. The vehicle body side rocking axis 151 arranged on the vehicle body side retaining part 150 is an axis parallel to the sliding door 50 and perpendicular to the opening and closing direction D11 of the sliding door 50.

[0087] By holding the bellows 120 using the vehicle body side retaining portion 150, the wiring harness 110 is held such that a portion of it on the vehicle body 60 side can swing in the XY plane about the vehicle body side rocking axis 151. The wiring harness 110 on the vehicle body 60 side protrudes from one end of the bellows 120 on the vehicle body 60 side. Furthermore, the wiring harness 110 protrudes from the vehicle body side retaining portion 150 through a channel (not shown) inside the vehicle body side retaining portion 150, and then extends to a power supply or control device (not shown) in the vehicle body 60.

[0088] like Figure 1 As shown, when the sliding door 50 is fully closed, the door-side retaining portion 140 is located at the front of the vehicle 5 relative to the body-side retaining portion 150. The bellows 120, that is, the wiring harness 110 on its inner side, extends in a straight line between the body-side retaining portion 150 and the door-side retaining portion 140.

[0089] When the sliding door 50 opens towards the rear of the vehicle 5 in the opening direction D111, in its initial stage, one end of the bellows 120 on the sliding door 50 side swings as follows. More specifically, when the sliding door 50 is fully closed, the end of the bellows 120 on the sliding door 50 side is located further from the door-side rocker axis 141 on the body-side retaining part side (rear side). When the sliding door 50 is opened, the aforementioned end swings forward about the door-side rocker axis 141 in the XY plane. When the sliding door is partially opened, this end is located further away from the body-side retaining part 150 (front side) than the door-side rocker axis 141. A coil spring can be arranged in the door-side retaining part 140 to facilitate such swinging. The coil spring applies force to the end of the bellows 120 on the sliding door 50 side in the force application direction D12.

[0090] Due to the aforementioned oscillation during the initial stage of opening the sliding door 50, when the sliding door 50 is subsequently moved in the opening direction D111, that is, when the sliding door 50 is partially opened, the wiring harness 110 inside the bellows 120 is bent as follows. More specifically, as... Figure 1 As shown, the wiring harness 110 is bent so that it presents a U-shape on the front side of the vehicle 5 from the body side retainer 150 toward the door side retainer 140 in the XY plane, and bends toward the outside of the body 60.

[0091] Furthermore, in the following text, unless otherwise specified, the wiring harness 110 inside the bellows 120 will simply be referred to as wiring harness 110.

[0092] When the sliding door 50 moves in the opening direction D111, the U-shaped arm of the wiring harness 110 on the sliding door 50 side extends linearly towards the front of the vehicle 5 due to the force applied in the force direction D12 at the door-side retaining part 140. Due to the movement of these parts and the movement of the bending control member 130 described below, the U-shape of the wiring harness 110 in the XY plane is adjusted during the movement of the sliding door 50.

[0093] As the sliding door 50 slides in the opening direction D111, the arm of the U-shaped wiring harness 110 extends at the sliding door 50, while its arm at the vehicle body 60 shortens. Then, at a stage where the arm of the wiring harness 110 at the vehicle body 60 has shortened to a certain extent, one end of the wiring harness at the side of the vehicle body swings towards the rear of the vehicle 5 in the swing direction D15. Subsequently, in this stage, the sliding door 50 moves in the opening direction D111 and then reaches the fully open state.

[0094] When the sliding door 50 closes from the fully open state in the closing direction D112, the wiring harness 110 moves in the opposite direction to the movement described above when the sliding door 50 was open. First, in its initial stage, one end of the wiring harness 110 on the vehicle body 60 side swings in the opposite direction of the swing direction D15, thus giving the wiring harness 110 a U-shape in the XY plane. Then, as the sliding door 50 continues to move in the closing direction D112 and the U-shaped arm on the sliding door 50 side shortens to a certain extent, one end of the wiring harness 110 on the sliding door side swings as follows: That is, in this stage, one end of the wiring harness 110 on the sliding door 50 side swings against the force applied in the door-side retaining portion 140 towards the rear of the vehicle 5, which is the opposite side of the force application direction D12. Then, in this stage, the sliding door 50 moves in the closing direction D112, and the wiring harness 110 extends linearly and reaches the fully closed state.

[0095] Here, the end of the floor of the vehicle body 60 on the side of the sliding door 50 can be formed as a step 61, which is a lower step and is used to place the feet of a passenger when boarding. When the sliding door 50 is opened and closed, the arm of the U-shaped harness 110 on the side of the vehicle body 60 approaches the step 61 in the XY plane.

[0096] In general, in the field of power supply devices for sliding doors of vehicles, there is a desire to suppress bulging towards the vehicle body side when the wiring harness bends during the opening and closing of the sliding door. Therefore, in this embodiment of the invention, in order to limit such bending of the wiring harness 110 towards the vehicle body 60 side, the bending control member 130 is positioned along the wiring harness 110. The bending control member 130 controls the bending of the wiring harness 110 in the XY plane. Furthermore, the bending control member 130 allows bending to make one side (the rear side of the vehicle 5 in this embodiment of the invention) in the height direction D13 inward. At the same time, regarding the bending of the other side in the height direction D13 inward (the front side of the vehicle 5 in this embodiment of the invention), the bending control member 130 limits the bending to exceed a predetermined limit state. Furthermore, the height direction D13 is a direction perpendicular to both the length direction D14 of the wiring harness 110 and the Z direction, which is a vertical direction perpendicular to the XY plane (and also the width direction D15 of the flat plate portion 132 of the bending control member 130).

[0097] Figure 2 It shows the composition Figure 1 A perspective view of a first example of the multiple unit sections 131 of the bending control component 130 shown.

[0098] like Figure 1 As shown, the bending control component 130 is located between the inner surface of the bellows 120 and the wire harness 110, thereby guiding bending around and along the wire harness 110 in the circumferential direction. The bending control component 130 has substantially the same length as the bellows 120.

[0099] The bending control component 130 has a plurality of unit segments 131 arranged along the wire harness and a flexible plate portion 132 connecting adjacent unit segments 131. In an embodiment of the invention, the plurality of unit segments 131 and the plate portion 132 may be integrally formed of resin. The plurality of unit segments 131 are arranged side by side along the longitudinal direction D14 of the wire harness 110. The plate portion 132 is a flexible component arranged along the wire harness 110 so as to be located inside the bending shape of the plurality of unit segments 131. Adjacent unit segments 131 are connected only by the plate portion 132. Thus, one unit segment among adjacent unit segments 131 can swing about the plate portion 132 relative to one of the adjacent unit segments 131. Adjacent unit sections 131 can engage with each other to control the curvature of the plate portion 132 in the XY plane, allowing one side of its height direction D13 (the opposite side of the protruding side of unit section 131) to be inward, while limiting the curvature of the other side of its height direction D13 (the protruding side of unit section 131) to be inward beyond a predetermined limit state.

[0100] The bending control member 130 includes a unit segment 131 with a protrusion 135 and a receiving portion 136 disposed in the length direction D14. The protrusion 135 of one unit segment 131 can engage with the receiving portion 136 of an adjacent unit segment 131, such that in the engaged state, the protrusion 135 and the receiving portion 136 restrict the displacement between unit segments 131 in the width direction D15 of the flat plate portion 132. The protrusion 135 of the unit segment 131 is formed in a shape that is inclined as it extends protruding toward the length direction D14, and the receiving portion 136 of the unit segment 131 is formed in a shape that matches the corresponding protrusion 135.

[0101] Based on the bending control component with the above-described structure, the bending shape of the wiring harness from the vehicle body to the sliding door can be precisely managed and controlled. This ensures that the wiring harness maintains necessary flexibility during movement while avoiding damage or performance degradation caused by excessive bending. By designing a protrusion and a receiving portion for each unit section, the protrusion can engage with the receiving portion of an adjacent unit section, and the receiving portion can receive the protrusion of another adjacent unit section. This simple structural design, through the interlocking engagement between unit sections, restricts the degree of freedom of movement of each unit section under bending stress. This restricts displacement between unit sections, at least in the width direction, thereby preventing accidental torsional deformation of the flat section and preventing failures such as wire clamping, deformation, and breakage of the bending control component, ensuring the stability of the wiring harness during bending. Furthermore, the protrusion extends protrudingly and tilts along its length, making the engagement process smoother and reducing wear and noise caused by friction or collision. The tilted shape also increases the contact area and friction between the protrusion and the receiving portion, further improving the stability and durability of the engagement.

[0102] The following will refer to the appendix. Figure 2-9 The structure of each unit section 131 is described in detail with three examples.

[0103] Figures 2-4A first example of a unit segment 131 of a bending control member 130 is shown. In this first example, the protrusion 135 of the unit segment 131 of the bending control member 130 is formed as an inclined tooth protruding from one end face 133 in the longitudinal direction D14 of the unit segment 131, such that at least one of the two sides of the protrusion 135 in the width direction D15, namely one side face 135A and the other side face 135B, is an inclined surface, so that the two sides 135A and 135B gradually approach each other as they move away from one end face 133. In this example, as shown in the figure, both one side face 135A and the other side face 135B are inclined surfaces. Correspondingly, the receiving portion 136 of the unit segment 131 is formed as a recessed portion that is recessed from the other end face 134 in the longitudinal direction D14 of the unit segment 131. Needless to say, the receiving portion 136 also has an inclined surface corresponding to the protrusion 135.

[0104] In the first instance, such as Figure 2 As shown, the two inclined sides 135A and 135B of the protrusion 135 of unit section 131 are inclined at an angle α of 8 to 12 degrees relative to the length direction D14. Additionally, the end face 135C of the protrusion 135 of unit section 131 in the length direction D14 can also be an inclined surface, for example, an inclined surface inclined at an angle β of 2 to 5 degrees relative to the height direction D13. By making the end face 135C inclined at this small angle, the protruding length of the protrusion 135 gradually increases as it gets closer to the flat plate 132. Utilizing this inclined end face arrangement, when the bending control member bends towards the opposite side of the flat plate 132, thus requiring the protrusion 135 of one unit section 131 to be inserted into the recessed receiving portion 136 of the adjacent unit section 131 for bending restriction, the inner end of the protrusion 135, which has a slightly longer protruding length near the flat plate 132 side (… Figure 2 The lower end of the segment 131 will first contact the corresponding receiving part 136, thereby playing a role in alignment and guidance and preventing slippage. In addition, one end face 133 and the other end face 144 of the unit segment 131 can also be formed as inclined surfaces parallel to the end face 135C of the protrusion 135, but this is not restrictive and it does not have to be an inclined surface.

[0105] According to the bending control component 130 of the first example, the protrusion 135 of the unit section 131 is designed as an inclined tooth protruding from an end face 133 in the length direction D14, so that the protrusion 135 can not only provide a biting point in the length direction D14, but also generate a constraint effect in the width direction D15 through its inclined shape, thereby realizing the control of the degree of freedom of the unit section 131 in both the length direction D14 and the width direction D15, and suppressing the displacement between the unit sections 131 in the length direction D14 and the width direction D15. Because at least one of the two sides 135A and 135B of the protrusion 135 in the width direction D15 is an inclined surface, the two sides gradually approach each other as they move away from one end face 133. Furthermore, the side of the receiving portion 136 that mates with it is also formed in a matching shape, i.e., an inclined surface. Therefore, when the protrusion 135 of one unit section 131 bites into the receiving portion 136 of the adjacent unit section 131, the biting process is smoother, reducing wear and noise caused by friction or collision. Moreover, when the biting is completed, it can be considered to form a "wedge" structure, enhancing the stability and reliability of the biting. In addition, by utilizing the aforementioned 8-12 degree inclination angle and 2-5 degree inclination angle of the protrusion 135 of the unit section 131, a balance between stability and flexibility can be achieved. This helps improve the performance and effectiveness of the bending control component and ensures that the wire harness maintains its predetermined shape and performance during bending, thus improving both the durability and user comfort of the component.

[0106] Figures 4-8 A second example of the unit segment 131 of the bending control member 130 is shown. Instead of the inclined tooth-like protrusion in the first example, in the second example, the protrusion 135 of the unit segment 131 of the bending control member 130 is formed as a frustum protruding from one end face 133 in the longitudinal direction D14 of the unit segment 131, such that when viewed from the width direction D15, the end face of the frustum is inclined in an arcuate manner, i.e., an inclined surface in the form of an arcuate surface or a circular arc surface, and the receiving portion 136 of the unit segment 131 is correspondingly formed as a recessed portion recessed from the other end face 134 in the longitudinal direction D14 of the unit segment. In this example, both sides of the frustum-shaped protrusion 135 in the width direction D15 are planar, but this is not limiting and other shapes are also possible.

[0107] According to the bending control component 130 with the above-described structure in the second example, the protrusion 135 of the unit section 131 is designed as a frustum shape, so that the end face of the part that engages with the corresponding receiving part 136 presents an arc-shaped inclined surface. Therefore, the engagement between the protrusion 135 and the receiving part 136 becomes a receiving engagement between an arc-shaped protrusion and an arc-shaped concave portion. This arc-shaped inclination provides a smooth transition and contact surface, ensuring that the protrusion 135 can be smoothly inserted and guided into the receiving part 136 and form a good fit. The degrees of freedom of the unit section 131 are controlled in the length direction D14, the height direction D13, and the width direction D15. Moreover, the frustum design increases the contact area between the protrusion 135 and the receiving part 136, which helps to disperse contact pressure, improve the stability and durability of the connection, and the arc-shaped inclined surface makes the force more uniform, reducing the risk of damage caused by stress concentration.

[0108] Similar to the first instance, in the second instance, see [link to example]. Figure 6 In this embodiment, one end face 133 of unit segment 131 and the other end face 134 are parallel to each other. The radius of the arc of protrusion 135 is the same as that of the arc of receiving portion 136. However, as shown in the figure, protrusion 135 and receiving portion 136 are not configured to be parallel to each other in this embodiment, but rather intersect each other at a small angle. In other words, the chord of the arc constituting receiving portion 136 is inclined at an angle δ of 2 to 5 degrees relative to the other end face 134, so that the chord of the arc constituting receiving portion 136 is further away from the other end face 134 as it moves away from the side of plate portion 132. Of course, this inclined configuration is not limiting. However, with this inclined configuration, when the bending control member bends toward the opposite side of plate portion 132 so that the protrusion of one unit segment is to be inserted into the receiving portion of the adjacent unit segment for bending restriction, the arc-shaped protrusion and the arc-shaped receiving portion first come into contact with each other on the side closer to plate portion 132 (the lower side in the figure), thereby playing a guiding alignment role and preventing slippage.

[0109] Figure 9A third example of the unit segment 131 of the bending control member 130 is shown. Instead of the inclined tooth-shaped protrusion in the first example and the frustum-shaped protrusion in the second example, in the third example, the protrusion 135 of the unit segment 131 of the bending control member 130 is formed to include a first part 131A and a second part 131B that are integral in the width direction D15 (in the view, the dashed line separating the first part 131A and the second part 131B is only for illustrative purposes and does not actually exist). In the upper part of the unit section 131 in the height direction D13, the first part 131A is offset from the second part 131B in the length direction D14, such that in the length direction D14, one end of the first part 131A protrudes from the second part 131B to form a first protrusion 135-1, and the other end of the first part 131A is recessed from the second part 131B to form a first recess 136-1. In the lower part of the unit section 131 in the height direction D13, the first part 131A is offset from the second part 131B in the length direction D14 in the opposite direction to that in the upper part, such that in the length direction D14, one end of the first part 131A is recessed from the second part 131B to form a second recess 136-2, and the other end of the first part 131A protrudes from the second part 131B to form a second protrusion 135-2.

[0110] According to the bending control component 130 with the above-described structure in the second example, the first part 131A of the unit section 131 is formed into a Z-shaped structure that is staggered vertically, and the second part 131B is a rectangle with the same vertical orientation. Thus, relative to the second part 131B, one end of the upper part of the first part 131A protrudes in the length direction D14 while the other end is recessed, and one end of the lower part of the first part 131A protrudes in the length direction D14 while the other end protrudes. Therefore, the unit sections 131 interlock in a Z-shape. During the bending of the flat plate portion 132, this Z-shaped interlocking between adjacent unit sections 131 controls the degrees of freedom of the unit section 131 in the length direction D14, height direction D13, and width direction D15 of the flat plate portion, providing stable support in multiple directions and reducing the swaying and displacement of the wire harness during movement.

[0111] In addition, such as Figure 9 In this third example, the protrusions 135 (first protrusion 135-1 and / or second protrusion 135-2) of the unit segment 131 also have an inclined angle, specifically, as shown in... Figure 9 The engagement surfaces 135S of the first protrusion 135-1 and the second protrusion 135-2 for engaging with the unit section 131 in the height direction D13 are inclined surfaces. Moreover, the inclined surfaces are inclined at an angle γ of 2 to 5 degrees with respect to the length direction D14.

[0112] According to the bending control component 130 with the above-described structure in the third example, the engagement surfaces of the first protrusion 135-1 and / or the second protrusion 135-2 for engaging with adjacent unit sections 131 in the height direction D13 are designed as inclined surfaces. This allows each protrusion to form a more stable contact relationship with each recess of the adjacent unit section during engagement. The inclined surfaces can guide and lock the protrusions, preventing accidental slippage or detachment during movement. Moreover, the inclined surfaces help to distribute the force at the engagement point, reducing stress concentration, which not only improves the durability of the engagement area but also reduces the risk of damage caused by uneven force distribution. In addition, the inclined surfaces can provide a certain guiding effect during engagement, reducing wear caused by friction. Furthermore, the inclined surfaces are inclined at an angle of 2 to 5 degrees relative to the length direction D14, so that when adjacent unit sections come into contact with each other, the mating inclined surfaces can fit better together, forming a stable contact relationship. When the unit section is subjected to external forces during bending, the inclined surfaces can provide additional support and restraint, and also help to distribute pressure between unit sections, avoiding damage caused by excessive force at a single point. Moreover, the design of this tilt angle allows adjacent unit sections to mesh more smoothly as the flat section changes from bending to straightening.

[0113] The bending control component of this utility model has been described above through three examples. It can effectively control the degrees of freedom of the unit sections in each direction, making the interlocking of the unit sections of the bending control component more reliable and preventing misalignment. Even if the power supply device is subjected to force during bending, it can suppress the misalignment between the unit sections to a certain extent, thereby suppressing the torsion of the flat part of the bending control component. This prevents failures such as wire clamping, deformation, and breakage of the bending control component, and can effectively reduce the occurrence of adverse situations such as the door not being able to open and close normally and the circuit not conducting due to the failure of the bending control component.

[0114] In addition, the attached drawings only show the unit section located on one side of the width direction of the plate portion; however, the unit section may also be symmetrically formed on the other side of the width direction.

[0115] Furthermore, the second aspect of this utility model also provides a power supply device 1 (see [reference needed]) installed in a vehicle 5 having a body 60 and a sliding door 50 and electrically connecting the body 60 and the sliding door 50. Figure 1 The power supply device 1 includes: a wiring harness 110 arranged between the vehicle body and the sliding door; and a bending control component 130 arranged along the wiring harness as described in the first aspect.

[0116] According to the power supply device 1 of the second aspect, since it includes a bending control component 130 as described in the first aspect arranged along the wire harness 110, it is able to achieve the same technical effect as described in the first aspect.

[0117] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
