[0002] During vehicle use, the trunk is the largest storage space in the vehicle and is frequently used by vehicle users. Therefore, there is a demand for a more convenient opening and closing of the trunk, and the electric tailgate came into being. It allows the operator to automatically open or close the tailgate by simply pressing the corresponding electric tailgate control button, greatly improving the user's vehicle experience. To achieve the automatic opening and closing function of the electric tailgate, a wiring harness needs to be installed to connect the corresponding switch.

[0003] There are two types of electric tailgates for sedans: hatchback and sedan-type. The tailgate support structure of the hatchback electric tailgate is arranged outside the luggage compartment, while the tailgate support structure of the sedan-type electric tailgate is different from that of the hatchback. The support structure is arranged inside the luggage compartment and generally includes a tension spring and a support rod on each side. The wiring harness should avoid the tension spring support rod and then be fixed on the tailgate hinge elbow to connect the electronic components on the tailgate.

[0004] The wiring harness of the current three-box ordinary electric tailgate is fixed on the support plate on the second row of seat backs to avoid tension springs or struts. However, when assembling the fixing points at these locations, due to the limitation of the rear overhang length, the workshop assemblers sometimes cannot reach the fixing points at the normal assembly station, and other assembly stations also have invisible problems, and there are problems with the assembly man-machine. Secondly, the wiring harness passes through the support plate on the second row of seat backs and the parcel shelf to the fixing point of the back door hinge elbow, which will expose the wiring harness outside the trunk decorative panel. Consumers have a chance to see this when taking items from the trunk, which has aesthetic defects. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0035] The terms "first", "second", etc. in the specification, claims, and drawings of the present disclosure are used to distinguish different objects rather than to describe a specific order. Terms such as "upper", "lower", etc. that indicate orientation are described based on the positional relationship of each component structure under normal use. They are only used to describe relative positional relationships and do not necessarily indicate limitations on orientation. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products, or devices.

[0036] In related technologies, such as Figure 1-Figure 2 As shown, in the prior art, the wiring harness 2 of the electric tailgate is arranged from the front end of the seat back support plate 03 of the rear row of the vehicle to the rear end of the seat back support plate 03, and passes through Figure 1The first harness fixing point 01 in the wiring harness is fixed to the two fixing points of the parcel shelf, and the harness goes through this path to the second harness fixing point 02, and finally connects to the electronic components of the electric tailgate. For this arrangement, when assembling the harness, the assembler needs to install the first harness fixing point 01 from the opening of the vehicle's rear door. The position of the assembler closest to the vehicle body during assembly is limited by the position of the rear anti-collision beam. If the rear anti-collision beam is located relatively far back, the assembler may not be able to reach the fixing point, resulting in the risk of being unable to assemble.

[0037] In addition, the harness routing from the seat back support plate to the parcel shelf would cause the harness to extend beyond the boundaries of the trunk trim 04, such as Figure 2 As shown. The wiring harness 2 is exposed outside the trunk decoration 04, which will cause many uncontrollable problems. There may be a risk that the wiring harness may be damaged by sharp objects stored in the trunk. The wiring harness here is the main wiring harness of the entire vehicle electrical system, which is equivalent to the most important aorta. Once damaged, the electronic devices in the entire rear of the vehicle are at risk of failure, which may have a significant impact on the user's normal vehicle use. Secondly, the wiring harness is exposed outside the covering of the trunk decoration, which will give consumers a negative impression of the product. When consumers open the trunk to take out items, they may see the uncovered wiring harness here, which will make them doubt whether the product design and assembly are not meticulous and rigorous enough.

[0038] In view of the risks of assembly ergonomics and aesthetics in the fixed position of the current three-box ordinary electric tailgate wiring harness, the disclosed embodiment changes the wiring harness path from the second-row seat back support plate to the tailgate hinge elbow to the lower inner plate of the C-pillar to the tailgate hinge elbow. By changing the position of the wiring harness fixing point, the wiring harness path is located in the assembly operable area, and the wiring harness is covered by the trunk decorative parts to avoid assembly and appearance risks. By changing the position of the wiring harness fixing point, the disclosed embodiment further provides a special wiring harness fixing buckle to solve the problems of poor ergonomics in the assembly of the electric tailgate wiring harness and the unsightly exposed wiring harness, and at the same time solves the problem of insufficient dynamic clearance between the wiring harness and the electric tailgate tension spring 4, avoiding the risk of the tension spring support rod clamping the wiring harness during the use of the electric tailgate, and improving product quality.

[0039] The disclosed embodiment proposes a wiring harness fixing structure that can be widely used in electric tailgates of Sedan vehicles from the perspective of final assembly and daily use scenarios of consumers. The wiring harness fixing points are arranged to facilitate installation by assemblers, and the wiring harness can be located under the covering of the trunk decorative parts, avoiding potential risks in the current solution. Once developed and used, the risk of complaints about production and products can be reduced, thereby improving product reliability.

[0040] Specifically, the embodiments of the present disclosure, such as Figure 3-Figure 5As shown, firstly, an electric tailgate harness fixing buckle 1 is provided, comprising a buckle body 10, a positioning buckle, a limit fixing buckle and a harness groove 13;

[0041] The positioning buckle is arranged on both sides of the buckle body 10, including a fixing portion 111 connected to the buckle body and a clamping spring 112 connected to the fixing portion. The clamping springs of the two positioning buckles are arranged opposite to each other, and the free ends of the clamping springs on the opposite sides have a protruding clamping column 113. The spacing between the clamping springs matches the width of the trunk lid hinge elbow 3.

[0042] The position-limiting fixing buckle is arranged on a side of the buckle body different from the positioning buckle, and includes a position-limiting fixing buckle protrusion 121, the direction of which is consistent with the length direction of the clamping spring piece;

[0043] The harness groove 13 is arranged on the buckle body, and the shape of the harness groove matches the harness path.

[0044] In some embodiments, the end of the fixing portion 111 facing one end of the snap-fit ​​spring sheet 112 extends upward along both sides of the snap-fit ​​spring sheet to form an extension portion 114, and there is a gap between the extension portion and the snap-fit ​​spring sheet. The provision of the extension portion can improve the fixing strength and achieve a firm fixation with the snap-fit ​​spring sheet. The snap-fit ​​spring sheet can achieve a certain amount of deformation and can reach the mounting hole with a certain amount of deformation during assembly.

[0045] The positioning buckle is used to be fixedly connected to the trunk lid hinge elbow 3 and is installed in the positioning holes opened on the left and right sides of the trunk lid hinge elbow. The part of the clamping column close to the clamping spring is a cylinder with a height of 1.3 mm, and the part away from the clamping spring is an inclined column with a gradually changing height, and the inclined surface of the inclined column faces the direction away from the fixing part, so that it is easy to clamp into the positioning hole during installation and not easy to fall out of the positioning hole.

[0046] In some embodiments, an assembly indication structure 115 is provided on the outer side of the fixing portion, and the assembly indication structure points to the clamping column of the clamping spring. The fixing point of the wiring harness 2 is located at the position of the hinge bend of the trunk lid close to the hinge base, and the fixing hole cannot be seen during assembly. Based on this, the embodiment of the present disclosure designs an arrow-shaped assembly indication structure on the wiring harness fixing buckle, so that the assembler can find the positioning hole through the assembly indication structure at the installation position and complete the installation of the structure. Through this wiring harness fixing buckle, the wiring harness path can be adjusted to an area that is convenient for assembly, and the wiring harness is also covered by the trunk decorative parts to solve the problem of the wiring harness being exposed.

[0047] In some embodiments, a cable tie hole 131 is provided at the bottom of the wire harness groove 13, through which a cable tie can pass, so as to fix the wire harness with the cable tie when assembling and installing the wire harness.

[0048] In some embodiments, the limiting fixing buckle protrusion 121 is a conical structure, so that when the buckle is installed on the trunk lid hinge bend tube, the limiting fixing buckle protrusion can be clamped into the limiting fixing hole 32 on the trunk lid hinge bend tube by rotating along the axis of the clamping column.

[0049] The disclosed embodiment further provides an electric tailgate wiring harness fixing structure, including a trunk lid hinge bend 3 and an electric tailgate wiring harness fixing buckle 1 provided above, wherein positioning holes 31 are provided at set positions on both sides of the trunk lid hinge bend for matching with the clamping columns 113 on the electric tailgate wiring harness fixing buckle 1; a limiting fixing hole 32 is provided at a set position on the upper part of the trunk lid hinge bend for matching with the upper limit fixing buckle protrusion 121 of the electric tailgate wiring harness fixing buckle 1; the positioning hole matches the shape and position of the clamping column of the electric tailgate wiring harness fixing buckle, and the limiting fixing hole matches the shape and position of the limiting fixing buckle protrusion of the electric tailgate wiring harness fixing buckle.

[0050] In some embodiments, the number of the electric tailgate harness fixing buckles is multiple, and the number of positioning holes and limiting fixing holes on the trunk lid hinge elbow matches the number of the electric tailgate harness fixing buckles. In this embodiment, three electric tailgate harness fixing buckles are used to clamp on the trunk lid hinge elbow, and there is a positioning hole on each of the left and right sides of the hinge elbow, and a limiting fixing hole on the upper surface of the hinge elbow.

[0051] An embodiment of the present invention further provides a vehicle, comprising the electric tailgate wiring harness fixing structure provided above.

[0052] like Figure 6(a)-Figure 6(c) As shown, during assembly, first install the electric tailgate harness fixing buckle according to the direction indicated by the assembly indication structure, and insert the clamping column into the positioning hole, as shown in Figure 6(b); then rotate the buckle counterclockwise, insert the limit fixing buckle protrusion into the limit fixing hole, as shown in Figure 6(c), and complete the buckle assembly. Finally, install the wire harness in the wire harness slot and use a cable tie to fix it to complete the wire harness installation.

[0053] The disclosed embodiment adjusts the wiring harness path based on the risks of the existing solution (the assembler is restricted by the length of the rear overhang, there is a risk of failure to assemble, and the risk of the wiring harness being exposed and visible when consumers take items from the trunk), improves the assembler and the risk of wiring harness exposure. Its advantage is that the fixed point position is convenient for the assembler to operate, and there is no need to tiptoe and stretch the body to install the wiring harness fixing point. At the same time, the electric tailgate wiring harness is covered by the trunk decoration, solving the problem of unsightly exposed wiring harness. The structure is simple and easy to implement, and can also be applied to the general structure of a three-box ordinary electric tailgate. After adaptation, it can match different models of the same type, becoming a platform solution.

[0054] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
