Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.
[0035] The terms "first," "second," etc., in this disclosure, claim, and drawings are used to distinguish different objects, not to describe a specific order. Terms indicating orientation, such as "upper" and "lower," are used to describe the relative positional relationship of the structural parts in their normal operating state and do not necessarily limit the orientation. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. 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 not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.
[0036] In related technologies, such as Figures 1-2 As shown, in the prior art, the wiring harness 2 of the electric tailgate is arranged from the front end of the rear seat back support plate 03 to the rear end of the rear seat back support plate 03, and then passes through... Figure 1The first wire harness fixing point 01 in the middle is fixed to two fixing points of the parcel shelf, and the wire harness passes through this path to the second wire harness fixing point 02 and is finally connected to the electronic components of the electric tailgate. For this arrangement, when the wire harness is assembled, the assembler needs to install the first wire harness fixing point 01 from the rear door opening of the vehicle. The position of the assembler closest to the vehicle body during assembly is limited by the position of the rear bumper beam. If the position of the rear bumper beam is relatively rear, the assembler may not be able to reach the fixing point, resulting in the risk of being unable to assemble.
[0037] In addition, the wire harness path from the seat back support plate to the parcel shelf will cause the wire harness to exceed the boundary of the trunk trim 04, as shown in Figure 2 The exposed wire harness 2 outside the trunk trim 04 will cause many uncontrollable problems. There is a risk that sharp objects stored in the trunk will damage the wire harness. The wire harness here is the main wire harness of the entire vehicle electrical system, which is equivalent to the most important aorta. Once damaged, there is a risk that the entire electronic device at the rear of the vehicle will fail, which may have a significant impact on the normal use of the vehicle by the user. Secondly, the exposed wire harness outside the covering of the trunk trim will cause the consumer to have a negative impression of the product in terms of aesthetics. When the consumer opens the trunk to take the items, they may see the wire harness that is not covered, which makes them doubt whether the product is designed and assembled with sufficient care and rigor.
[0038] In view of the assembly man-machine risk and aesthetic risk of the fixing position of the wire harness of the current three-door ordinary electric tailgate, the wire harness path from the second-row seat back support plate to the rear door hinge elbow pipe is changed to the wire harness path from the lower inner panel of the C pillar to the rear door hinge elbow pipe in the embodiments of the present disclosure. By changing the position of the wire harness fixing point, the wire harness path is located in the assembly operable area, and the wire harness is covered by the trunk trim, avoiding the assembly and appearance risks. The embodiments of the present disclosure further provide a special wire harness fixing buckle to solve the problems of electric tailgate wire harness assembly man-machine difference and wire harness exposure unsightliness, and solve the problem of insufficient dynamic gap between the wire harness and the electric tailgate tension spring 4, avoid the risk of the tension spring support rod clamping the wire harness during use of the electric tailgate, and improve the product quality.
[0039] The embodiments of the present disclosure propose a wire harness fixing structure that can be widely applied to electric tailgates of Sedan vehicles from the perspective of total assembly and consumer daily use scenarios. The wire harness fixing point is arranged to be easily installed by the assembler, and the wire harness can be covered by the trunk trim, avoiding the potential risks in the current solution. Once developed and used, the risk of complaints about production and products can be reduced, and the product reliability can be improved.
[0040] Specifically, the embodiments of the present disclosure, as shown in Figures 3-5As shown, first, an electric tailgate wire harness fixing buckle 1 is provided, including a buckle body 10, a positioning buckle, a limiting fixing buckle, and a wire harness groove 13;
[0041] The positioning buckle is arranged on both sides of the buckle body 10, including a fixed part 111 connected with the buckle body and a clamping elastic sheet 112 connected with the fixed part, the clamping elastic sheets of the two positioning buckles are oppositely arranged, the free end of the opposite side of the clamping elastic sheet has a protruding clamping column 113, and the spacing between the clamping elastic sheets matches the width of the trunk lid hinge elbow pipe 3.
[0042] The limiting fixing buckle is arranged on the side of the buckle body different from the positioning buckle, including a limiting fixing buckle protrusion 121, and the direction of the limiting fixing buckle protrusion is consistent with the length direction of the clamping elastic sheet.
[0043] The wire harness groove 13 is arranged on the buckle body, and the shape of the wire harness groove matches the wire harness path.
[0044] In some embodiments, the fixed part 111 extends upwards along both sides of the clamping elastic sheet to form an extension part 114 at one end of the clamping elastic sheet, and there is a gap between the extension part and the clamping elastic sheet. The arrangement of the extension part can improve the fixing strength and realize firm fixing in cooperation with the clamping elastic sheet. The clamping elastic sheet can realize a certain amount of deformation, and can reach the mounting hole with a certain deformation amount during assembly.
[0045] The positioning buckle is used for fixed connection with the trunk lid hinge elbow pipe 3 and is arranged in the positioning hole arranged on the left and right side surfaces of the trunk lid hinge elbow pipe. The part of the clamping column close to the clamping elastic sheet is a cylinder with a height of 1.3 mm, the part away from the clamping elastic sheet is a slope column with a height gradient, and the slope of the slope column faces away from the fixed part, so as to facilitate the clamping into the positioning hole during installation and not to be easily taken out of the positioning hole.
[0046] In some embodiments, the outer side surface of the fixed part is provided with an assembly indication structure 115, and the assembly indication structure points to the clamping column of the clamping elastic sheet. The fixing point of the wire harness 2 is at the position of the trunk lid hinge elbow pipe close to the hinge base, and the fixing hole cannot be seen during assembly. Therefore, the assembly indication structure in the shape of an arrow is designed on the wire harness fixing buckle, so that the assembly personnel can find the positioning hole through the assembly indication structure at the installation position, and the installation of the structure is completed. Through the wire harness fixing buckle, the wire harness path can be adjusted to the area convenient for assembly, and the wire harness is also covered by the trunk trim part, so that the problem of wire harness exposure is solved.
[0047] In some embodiments, the bottom of the wire harness groove 13 is provided with a cable tie hole 131 through which the cable tie can pass, and the cable tie is used to fix the wire harness during assembly and installation of the wire harness.
[0048] In some embodiments, the limiting and fixing buckle protrusion 121 has a conical structure, which facilitates the insertion of the limiting and fixing buckle protrusion into the limiting and fixing hole 32 on the luggage compartment lid hinge bend tube by rotating it along the axis of the locking post when the buckle is installed on the luggage compartment lid hinge bend tube.
[0049] This disclosure 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. Positioning holes 31 are provided at predetermined positions on both sides of the trunk lid hinge bend to match the snap-fit posts 113 on the electric tailgate wiring harness fixing buckle 1. Limiting fixing holes 32 are provided at predetermined positions on the upper part of the trunk lid hinge bend to match the upper limit fixing buckle protrusion 121 of the electric tailgate wiring harness fixing buckle 1. The positioning holes match the shape and position of the snap-fit posts of the electric tailgate wiring harness fixing buckle, and the limiting fixing holes match 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 wiring harness fixing clips is multiple, and the number of positioning holes and limiting fixing holes on the trunk lid hinge bend tube matches the number of electric tailgate wiring harness fixing clips. In this embodiment, three electric tailgate wiring harness fixing clips are used to snap onto the trunk lid hinge bend tube. There is a positioning hole on each of the left and right sides of the hinge bend tube, and a limiting fixing hole on the upper surface of the hinge bend tube.
[0051] The present invention further provides a vehicle, the vehicle including the electric tailgate wiring harness fixing structure provided above.
[0052] like Figures 6(a)-6(c) As shown in Figure 6(b), during assembly, first install the electric tailgate wiring harness fixing clips according to the direction indicated by the assembly instruction structure, and insert the clip pins into the positioning holes; then rotate the clips counterclockwise to insert the limiting fixing clip protrusions into the limiting fixing holes, as shown in Figure 6(c), completing the clip assembly. Finally, install the wiring harness in the wiring harness groove and secure it with cable ties to complete the wiring harness installation.
[0053] This disclosed embodiment addresses the risks of existing solutions (the assembly man-machine interface is limited by the rear overhang, posing a risk of assembly failure, and the risk of exposed wiring harnesses when consumers retrieve items from the trunk). It adjusts the wiring harness path to improve the assembly man-machine interface and reduce the risks of exposed wiring harnesses. Its advantages include convenient mounting point locations for assembly personnel, eliminating the need to tiptoe or lean out to install the wiring harness, and keeping the power tailgate wiring harness covered by the trunk trim, thus solving the problem of unsightly exposed wiring harnesses. The structure is simple and easy to implement, and it can also be applied to the common structure of ordinary three-box power tailgates. After adaptation, it can be matched with different models of the same type, becoming a platform-based solution.
[0054] The above merely provides preferred embodiments of the present disclosure, and is not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the principles and technical scope of the present disclosure shall fall into the scope of the present disclosure.
