Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a tailgate assembly and a vehicle. Background Technology

[0002] A spoiler is a common exterior component installed above the tailgate of a car. It not only improves the aerodynamic performance of the rear of the vehicle but also typically integrates functions such as a high-mounted brake light and a reversing camera. Currently, the spoiler wiring harness passes directly through a hole in the outer tailgate panel and enters the cavity between the inner and outer panels before electrically connecting to the tailgate wiring harness. When the spoiler is narrow, the wiring space inside the spoiler is limited, making it difficult for the spoiler wiring harness to obtain sufficient routing space within the spoiler to align with the through-hole position on the tailgate. This results in difficulties in connecting the spoiler wiring harness to the tailgate wiring harness, leading to low assembly efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide a tailgate assembly and vehicle, which aims to solve at least one of the aforementioned technical problems.

[0004] To achieve the above objectives, embodiments of the present invention provide a tailgate assembly, the tailgate assembly comprising: A back door panel, the back door panel having a recessed portion and a mounting portion located on the upper side of the recessed portion, the mounting portion having a wire passage notch; A tailgate wiring harness, one end of which extends to the recessed portion, and the other end of which is connected to the vehicle body wiring harness; A spoiler is provided at the mounting portion; Electrical components, disposed on the spoiler; and The spoiler wiring harness has one end electrically connected to the electrical component and the other end passing through the wire passage notch and electrically connected to the tailgate wiring harness.

[0005] In one embodiment, in the thickness direction of the back panel, the through-line notch has a first notch and a second notch that are connected, the first notch and the second notch having different widths to form an adhesive application step at the connection position of the first notch and the second notch, the adhesive application step being used to apply sealant.

[0006] In one embodiment, the back panel includes an outer panel and an inner panel, the middle portion of the inner panel is recessed towards the outer panel to form the recessed portion, the edges of the outer panel and the inner panel are fixedly connected to form the mounting portion, the first notch is provided in the outer panel, and the second notch is provided in the inner panel.

[0007] In one embodiment, the width of the first notch is smaller than the width of the second notch.

[0008] In one embodiment, the outer panel has a flange, one end of which is connected to the outer panel, and the other end of which abuts against the inner panel on the side surface opposite to the outer panel. The first notch penetrates the flange.

[0009] In one embodiment, a sealing ring platform is provided on the side surface of the rear door panel facing away from the spoiler, and a wiring space is formed between the sealing ring platform and the wiring notch. The spoiler wiring harness is at least partially located in the wiring space, and the recess is located inside the sealing ring platform.

[0010] In one embodiment, the sealing ring platform is provided with a wiring harness through hole, the wiring harness through hole is connected to the recess, and one end of the spoiler wiring harness passes through the wiring harness through hole and is electrically connected to the tailgate wiring harness.

[0011] In one embodiment, the side surface of the rear door panel facing away from the spoiler is provided with a wiring harness assembly hole, which communicates with the wiring harness through hole.

[0012] In one embodiment, the rear door assembly further includes a conduit, one end of which is connected to the spoiler, and the other end of which is connected to the sealing ring platform. The conduit is sleeved outside the spoiler wiring harness.

[0013] In one embodiment, the outer periphery of the conduit is provided with a sealing flange, which seals the through hole of the wire harness.

[0014] In one embodiment, the surface of the rear door panel is provided with a mounting recess, and the spoiler is disposed in the mounting recess.

[0015] To achieve the above objectives, embodiments of the present invention provide a vehicle comprising the aforementioned tailgate assembly.

[0016] The technical solution of this application, by setting a wiring notch at the edge of the tailgate panel, allows the spoiler wiring harness to smoothly extend from the outside to the inside of the tailgate panel through the notch. It then passes through the sealing ring in the open space inside the tailgate panel and connects electrically with the tailgate wiring harness. This eliminates the need for complex wiring operations in narrow installation gaps, facilitating wiring harness arrangement and assembly, reducing operator workload, and improving assembly efficiency on the production line. Furthermore, after passing through the notch, the spoiler wiring harness is guided to the inside of the tailgate panel, with the overall wiring path hidden within the tailgate panel and not exposed on its outer surface. Since the wiring notch is located on the side of the mounting portion facing away from the recess, it can be covered by the spoiler and is invisible from the outside of the vehicle, improving the overall aesthetic consistency of the rear of the vehicle.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope required by the embodiments of the present invention.

[0026] This application discloses a tailgate assembly and a vehicle. It is understood that the tailgate assembly is applied to a vehicle and is a component of the vehicle. That is, the vehicle includes the tailgate assembly. Optionally, the tailgate assembly can be applied to an SUV or other types of vehicles.

[0027] Furthermore, the vehicle also includes a body body with a receiving cavity, commonly referred to as a trunk. The receiving cavity has an opening, and a tailgate assembly is rotatably positioned at the opening to open or close the receiving cavity.

[0028] Furthermore, the tailgate assembly and the vehicle body are connected by hinges. It can be understood that the tailgate assembly, the vehicle body, and the hinges together form the vehicle body, which is a major component of the vehicle.

[0029] Furthermore, the tailgate assembly includes a tailgate panel and multiple power modules located at different positions on the tailgate panel. In this embodiment, there may be three power modules: the first power module includes a spoiler, a power component mounted on the spoiler, and a spoiler wiring harness electrically connected to the power component; the second power module includes an electric strut and a strut wiring harness electrically connected to the electric strut; and the third power module includes a through light and a through light wiring harness electrically connected to the through light. Of course, in other embodiments, the power modules may also be taillights, electronic locks, etc.

[0030] It should be noted that the tailgate assembly proposed in this application is a windshieldless tailgate, which can break free from the constraints of a rear window and allow for a purer and more dynamic tailgate structure design, meeting the higher aesthetic demands of mid-to-high-end models. Of course, in other embodiments, the tailgate assembly can also be a tailgate with a windshield, which will not be described in detail here.

[0031] Next, the structure and connection relationships of each of the above components will be introduced.

[0032] like Figures 2 to 4 As shown, an embodiment of the present invention proposes a tailgate assembly, the tailgate assembly comprising: The tailgate panel 3 has a sealing ring platform 311 on its inner side, and the inner side of the sealing ring platform 311 has a recess 312. It can be understood that the tailgate panel 3 is the main structure of the tailgate assembly, and can adopt commonly used structural designs, which will not be detailed further. The tailgate panel 3 and the vehicle body 1 are sealed by the sealing ring platform 311, effectively preventing external moisture, dust, and noise from entering the vehicle interior, ensuring the sealing performance of the rear of the vehicle. Optionally, a sealing ring can be provided on the sealing ring platform 311, which can form an elastic pressure seal with the corresponding area of ​​the vehicle body 1 when the tailgate panel 3 is closed. The tailgate wiring harness 5 has one end extending into the recess 312, and the other end connecting to the vehicle body wiring harness. Specifically, the tailgate wiring harness 5 extends into the recess 312, which allows it to be stored and reduces the height of the harness protruding from the tailgate panel 3, thus reducing the thickness of the tailgate panel 3. Specifically, the tailgate wiring harness 5 is electrically connected to the vehicle body wiring harness. It can be understood that the tailgate wiring harness 5 is used to transmit electrical energy from the vehicle body wiring harness to the tailgate panel 3, facilitating the establishment of an electrical connection between the electrical components on the tailgate panel 3 and the vehicle body wiring harness. In other words, the tailgate wiring harness 5 serves as the main wiring harness on the tailgate panel 3 and is directly electrically connected to the vehicle body wiring harness. Furthermore, the various power modules 4 on the tailgate panel 3 are directly electrically connected to the tailgate wiring harness 5, thereby achieving an electrical connection with the vehicle body wiring harness. The end of the tailgate wiring harness 5 furthest from the body wiring harness is located in the recess 312, which allows for at least partial concealment of the tailgate wiring harness 5, reducing the amount of wiring harness exposed on the surface of the tailgate panel 3 and resulting in better aesthetic consistency. Optionally, the tailgate wiring harness 5 passes through the upper part of the tailgate panel 3 and extends into the recess 312, which can further reduce wiring harness exposure and improve the aesthetic consistency of the tailgate panel 3; and At least two power modules 4 are provided, each located on the outer periphery of the sealing ring platform 311, and at least two power modules 4 are electrically connected to the tailgate wiring harness 5. It can be understood that multiple power modules 4 are directly electrically connected to the tailgate wiring harness 5, establishing an electrical connection with the vehicle body wiring harness through the tailgate wiring harness 5. Compared to each power module 4 being directly electrically connected to the vehicle body wiring harness, this reduces the complexity of the overall vehicle wiring harness layout, improves wiring convenience, and enhances the vehicle's appearance consistency. It should be noted that the outer periphery of the sealing ring platform 311 refers to the area outside the inner wall of the sealing ring platform 311; that is, all locations outside the inner wall of the sealing ring platform 311 are considered the outer periphery of the sealing ring platform 311.

[0033] In the technical solution adopted in this embodiment, by first converging the lines of multiple power modules 4 to the tailgate wiring harness 5, and then connecting them to the body wiring harness via the tailgate wiring harness 5, the number of reserved wiring points on the side of the body can be reduced, the number of openings in the body sheet metal and the number of wiring channels can be reduced, the overall layout complexity of the vehicle wiring harness can be effectively reduced, the convenience of wiring operation can be improved, and the appearance defects such as exposed excess wiring harnesses and messy wiring can be reduced, thereby improving the regularity of the wiring harness layout around the tailgate panel 3 and the consistency of the interior and exterior appearance of the vehicle.

[0034] In one embodiment, refer to Figure 3 and Figure 4 One power module 4 includes: An electric strut 411 is provided, with one end connected to the tailgate panel 3 and the other end connected to the vehicle body 1. It is understood that the electric strut 411 drives the tailgate panel 3 to rotate, thereby opening or closing the receiving cavity 11. The specific form of the electric strut 411 can be referenced from existing product structures and will not be detailed further. Optionally, two sets of electric struts 411 are symmetrically arranged along the width direction of the vehicle. Specifically, the electric struts 411 are located on the outer periphery of the sealing ring platform 311; and The strut harness 412 is located on the inner side of the tailgate panel 3. One end of the strut harness 412 is electrically connected to the electric strut 411, and the other end extends to the recess 312 and is electrically connected to the tailgate harness 5. It can be understood that the strut harness 412 is used to provide power to the electric strut 411; that is, one end of the strut harness 412 is electrically connected to the tailgate harness 5, and the other end is electrically connected to the electric strut 411, thereby transmitting the power from the tailgate harness 5 to the electric strut 411, providing power for the operation of the electric strut 411. Furthermore, the strut harness 412 is located on the side of the tailgate panel 3 facing the vehicle body 1, meaning the side of the tailgate panel 3 facing the opening 12 of the receiving cavity 11 is the inner side. Compared to the electric support rod 411, where the support rod wiring harness 412 is located above the electric support rod 411, the support rod wiring harness 412 will not be exposed after the tailgate panel 3 is opened. That is, the support rod wiring harness 412 can be close to the surface of the tailgate panel 3 and rotate with the tailgate panel 3, reducing the messiness of the wiring harness and making the appearance of the tailgate panel 3 more consistent when it is opened. Optionally, the support rod wiring harness 412 and the tailgate wiring harness 5 can be plugged in, soldered, etc., which is not limited here. Furthermore, the support rod wiring harness 412 is led out from the end of the electric support rod 411 near the tailgate panel 3, which facilitates the electrical connection to the tailgate wiring harness 5 in the recess 312.

[0035] In the technical solution adopted in this embodiment, during the opening process of the tailgate panel 3, the support rod harness 412 is closely attached to the surface of the tailgate panel 3 and rotates synchronously with the tailgate panel 3. It will not be exposed in the opening and closing gap between the tailgate panel 3 and the vehicle body 1, eliminating the messy hanging of the support rod harness 412, improving the integrity and uniformity of the appearance of the opening and closing area of ​​the rear of the vehicle, and enhancing visual consistency. Moreover, the support rod harness 412 will be closely attached to the surface of the tailgate panel 3 and will not swing significantly in the air, avoiding the problem of entanglement and messiness between the support rod harness 412 and other harnesses, and improving the neatness and orderliness of the harness layout.

[0036] In one embodiment, the strut harness 412 extends through the sealing ring platform 311 to the recess 312. This avoids the strut harness 412 crossing the sealing ring platform 311, facilitates the extension of the strut harness 412 into the recess 312, and reduces the adverse effect on the seal between the tailgate panel 3 and the vehicle body 1.

[0037] In one embodiment, refer to Figure 3 , Figure 4 as well as Figure 8 The back panel 3 is provided with a wiring harness through hole 321. The support rod wiring harness 412 passes through the wiring harness through hole 321 and through the sealing ring platform 311, extending to the recessed portion 312. Specifically, the wiring harness through hole 321 allows the support rod wiring harness 412 to easily extend into the recessed portion 312 and electrically connect with the back panel wiring harness 5. Optionally, the wiring harness through hole 321 faces the electric support rod 411, so that the support rod wiring harness 412 leading from the electric support rod 411 can directly extend into the recessed portion 312 through the wiring harness through hole 321, reducing the bending of the support rod wiring harness 412. Furthermore, the wiring harness through hole 321 is located below the electric support rod 411, so that the support rod wiring harness 412 leading from the electric support rod 411 will hang down naturally, facilitating its entry into the wiring harness through hole 321.

[0038] In one embodiment, the wiring harness through-hole 321 is provided with sealant, and the strut wiring harness 412 and the wiring harness through-hole 321 are sealed together by the sealant. It is understood that the sealant can achieve a seal between the strut wiring harness 412 and the wiring harness through-hole 321, improving the sealing performance of the recess 312, reducing wind noise, and simultaneously fixing the strut wiring harness 412 in the wiring harness through-hole 321, preventing the strut wiring harness 412 from swinging, reducing friction between the strut wiring harness 412 and the edge of the wiring harness through-hole 321, and improving the service life of the strut wiring harness 412.

[0039] In one embodiment, refer to Figure 3 , Figure 4 as well as Figure 8The recessed portion 312 is provided with a wire harness assembly hole 322, which communicates with the wire harness through hole 321. Understandably, when assembling the wire harness, the operator's hand can pull the support rod wire harness 412 out to the recessed portion 312 through the wire harness assembly hole 322, improving the convenience of connecting the back door wire harness 5 and the support rod wire harness 412. Additionally, in special circumstances, tools such as wires can be inserted through the wire harness assembly hole 322 to pull the support rod wire harness 412 out to the recessed portion 312 for inspection or maintenance. Optionally, the shape of the wire harness assembly hole 322 can be square, circular, etc., and is not limited here. Furthermore, the wire harness assembly hole 322 can be provided with a cover, which is movably connected to the back door panel 3, such as through a rotating connection or a sliding connection, to open or close the wire harness assembly hole 322. Furthermore, the wiring harness assembly hole 322 is located on the inner side of the sealing ring platform 311, which can avoid the narrow area on the outer side of the sealing ring platform 311, providing sufficient operating space for the operator and improving the convenience of connecting the support rod wiring harness 412 and the back door wiring harness 5.

[0040] In one embodiment, the wire harness mounting hole 322 is located below the wire harness through hole 321, so that the strut wire harness 412 can hang down under its own weight and be pulled out smoothly from the wire harness mounting hole 322.

[0041] In one embodiment, the wire harness assembly hole 322 is positioned opposite to the wire harness through hole 321. Thus, when the sealant seals the wire harness through hole 321 and the strut wire harness 412, an endoscope can be inserted through the wire harness assembly hole 322 to observe the sealing process, allowing for timely adjustment of the sealant's sealing position and improving sealing reliability.

[0042] In one embodiment, refer to Figure 4 The outer wall of the sealing ring platform 311 is provided with a clearance recess 313, and the wiring harness through hole 321 is located in the clearance recess 313. Specifically, the clearance recess 313 provides wiring space for the strut wiring harness 412, facilitating its arrangement. Moreover, with the wiring harness through hole 321 located in the clearance recess 313, the strut wiring harness 412 can pass through the side wall of the sealing ring platform 311. The strut wiring harness 412 is constrained in the clearance recess 313 and will not enter the closing gap of the tailgate panel 3, reducing the adverse effects on the sealing of the tailgate panel 3 and the vehicle body 1.

[0043] In one embodiment, refer to Figure 4The clearance recess 313 has a first sidewall 3131 and a second sidewall 3132 arranged adjacent to each other, and the included angle between the first sidewall 3131 and the second sidewall 3132 is an obtuse angle. In this way, the area of ​​the wiring space provided by the clearance recess 313 can be increased, and the strut harness 412 can be bent at a larger angle in the clearance recess 313, avoiding cracking or breakage of the strut harness 412 due to too small a bending angle, and improving the service life of the strut harness 412.

[0044] In one embodiment, the strut harness 412 is located below the electric strut 411. Thus, the strut harness 412 can hang naturally, allowing it to pass through the sealing ring platform 311 and extend into the recess 312, thereby electrically connecting to the back door harness 5.

[0045] In one embodiment, refer to Figure 5 The rear door panel 3 also has a mounting portion 314 located on the upper side of the recess 312. The mounting portion 314 is provided with a wire notch 3141. It can be understood that the recess 312 is formed in the middle of the rear door panel 3, and the mounting portion 314 is formed on the edge of the rear door panel 3, which can be used to install decorative parts such as the spoiler 421.

[0046] In one embodiment, refer to Figure 9 and Figure 10 One power module 4 includes: Spoiler 421 is provided on mounting part 314. Specifically, spoiler 421 can be fixed to mounting part 314 by bolts or the like. The specific structure of spoiler 421 can be referred to existing products and will not be described in detail here. Electrical component 422, located on spoiler 421, can be at least one of a brake light or a camera. That is, a brake light, a camera, or both can be mounted on spoiler 421. Optionally, the brake light and camera are sequentially arranged along the length of spoiler 421 (i.e., the width of the vehicle) and can be fixed to spoiler 421 by bolts, etc., which is not limited here. The specific structures of the brake light and camera can be found in existing products and will not be detailed further. The spoiler wiring harness 423 has one end electrically connected to the electrical component 422, and the other end passes through the wiring notch 3141 and is electrically connected to the tailgate wiring harness 5. Specifically, the spoiler wiring harness 423 is used to provide power to the electrical component 422. It can be understood that the spoiler wiring harness 423 electrically connects the tailgate wiring harness 5 and the electrical component 422, thereby transferring the power from the tailgate wiring harness 5 to the electrical component 422. For the smaller spoiler 421, after the spoiler 421 is installed on the tailgate panel 3, it is closer to the edge of the tailgate panel 3 and cannot directly pass through the recess 312 to electrically connect with the tailgate wiring harness 5. Therefore, this embodiment provides a wiring notch 3141 on the edge of the tailgate panel 3. Specifically, the wiring notch 3141 is provided on the surface of the mounting portion 314 facing away from the recess 312. The spoiler wiring harness 423 can first extend through the wire notch 3141 to the inside of the tailgate panel 3 (i.e. the side facing away from the spoiler 421), and then pass through the sealing ring platform 311 on the inside of the tailgate panel 3 and extend into the recess 312, thereby connecting with the tailgate wiring harness 5. This makes wiring more convenient and avoids the spoiler wiring harness 423 being exposed on the outside of the tailgate panel 3, improving the consistency of appearance and making it more aesthetically pleasing.

[0047] In this embodiment, by providing a wiring notch 3141 at the edge of the tailgate panel 3, the spoiler wiring harness 423 can smoothly extend from the outside of the tailgate panel 3 to the inside of the tailgate panel 3 via the wiring notch 3141. Then, it passes through the sealing ring 311 in the open space inside the tailgate panel 3 and connects electrically with the tailgate wiring harness 5. This eliminates the need for complex wiring operations in narrow installation gaps, facilitating wiring harness arrangement and assembly, reducing the labor intensity of operators, and improving assembly efficiency on the production line. Furthermore, after passing through the wiring notch 3141, the spoiler wiring harness 423 is guided to the inside of the tailgate panel 3, with the overall wiring path hidden inside the tailgate panel 3 and not exposed on its outer surface. Since the wiring notch 3141 is located on the side of the mounting portion 314 facing away from the recessed portion 312, it can be covered by the spoiler 421 and is invisible from the outside of the vehicle, improving the overall appearance consistency of the rear of the vehicle.

[0048] In one embodiment, refer to Figure 5 and Figure 7In the thickness direction of the back panel 3, the wiring notch 3141 has a first notch 31411 and a second notch 31412 that are connected. The widths of the first notch 31411 and the second notch 31412 are different to form an adhesive application step at the connection point of the first notch 31411 and the second notch 31412. The adhesive application step is used to apply sealant. The edges of the back panel 3 are usually fixed together by glue or welding. Providing the wiring notch 3141 at the edge of the back panel 3 may damage the glue or welding, affecting the sealing performance of the recess 312. Therefore, in this embodiment, the wiring notch 3141 includes a first notch 31411 and a second notch 31412 with different widths. The adhesive application step formed at the connection point of the first notch 31411 and the second notch 31412 facilitates the application of sealant and improves the sealing performance of the recess 312. It should be noted that the difference in width between the first notch 31411 and the second notch 31412 refers to the difference in size between the two notches in the width direction of the vehicle, or the difference in size between the two notches in the height direction of the vehicle, or the difference in size between the two notches in both the width and height directions of the vehicle.

[0049] In one embodiment, refer to Figure 6 and Figure 7 The rear door panel 3 includes an outer panel 33 and an inner panel 34. The middle part of the inner panel 34 is recessed towards the outer panel 33 to form a recessed portion 312. The edges of the outer panel 33 and the inner panel 34 are fixedly connected to form a mounting portion 314. A first notch 31411 is provided in the outer panel 33, and a second notch 31412 is provided in the inner panel 34. That is, the rear door panel 3 includes an inner panel 34 and an outer panel 33. The inner panel 34 and the outer panel 33 are fastened together to form a rear door panel 3 with a recessed portion 312. In other words, the edges of the inner panel 34 and the outer panel 33 are fixed together, and a recessed portion 312 is provided at a distance in the middle. A mounting portion 314 is formed in the area where the edges of the inner panel 34 and the outer panel 33 are fixed. Along the thickness direction of the rear door panel 3, the first notch 31411 penetrates the outer panel 33, and the second notch 31412 penetrates the inner panel 34, so that the spoiler wiring harness 423 can be guided to the inside of the rear door panel 3, that is, the side of the inner panel 34 facing away from the outer panel 33. Optionally, a cavity can be formed between the inner plate 34 and the outer plate 33. By applying sealant to the adhesive application step, the sealing performance of the cavity can be improved, and wind noise can be reduced. In addition, the strut harness 412 and the spoiler harness 423 first enter the cavity, then pass through the inner plate 34, and extend to the recess 312.

[0050] In one embodiment, the width of the first notch 31411 is smaller than the width of the second notch 31412. Thus, the adhesive application step is formed on the inner panel 34, meaning adhesive can be applied to one side of the inner panel 34. The applied sealant is located on the side of the outer panel 33 facing the inner panel 34, and is not exposed on the side of the outer panel 33 facing away from the inner panel 34, further improving the overall appearance consistency of the rear of the vehicle and enhancing its aesthetics.

[0051] In one embodiment, refer to Figure 5 and Figure 7 The outer panel 33 has a flange 331, one end of which is connected to the outer panel 33, and the other end of which abuts against the surface of the inner panel 34 facing away from the outer panel 33. A first notch 31411 penetrates the flange 331. It is understood that the flange 331, being bent and connected to the outer panel 33, can extend to the side of the inner panel 34 facing away from the outer panel 33 and abut against it, increasing the contact area between the outer panel 33 and the inner panel 34 and improving the reliability of their fixation. The first notch 31411 penetrating the flange 331 ensures that the spoiler wiring harness 423 can be smoothly guided to the side of the inner panel 34 facing away from the outer panel 33.

[0052] In one embodiment, a wiring space is formed between the sealing ring 311 and the wiring notch 3141, and the spoiler wiring harness 423 is at least partially disposed in the wiring space. Thus, the spoiler wiring harness 423 can be bent and arranged within the wiring space. In other words, by reserving wiring space, the wiring convenience of the spoiler wiring harness 423 is improved, and the spoiler wiring harness 423 can also be constrained within the wiring space, improving the neatness of the wiring harness arrangement.

[0053] In one embodiment, refer to Figure 3 and Figure 5 The sealing ring platform 311 is provided with a wiring harness through hole 323, which communicates with the recessed portion 312. One end of the spoiler wiring harness 423 passes through the wiring harness through hole 323 and is electrically connected to the tailgate wiring harness 5. It can be understood that the spoiler wiring harness 423 is first guided to the side of the inner plate 34 facing away from the outer plate 33 by the wire passing notch 3141, and then passes through the sealing ring platform 311 through the wiring harness through hole 323 and extends to the recessed portion 312, thereby realizing the electrical connection with the tailgate wiring harness 5.

[0054] In one embodiment, refer to Figure 3 and Figure 5 as well as Figure 9The rear door panel 3 has a wiring harness assembly hole 324 on the side facing away from the spoiler 421, which communicates with the wiring harness through hole 323. Understandably, during wiring harness assembly, the operator can use their hand to pull the spoiler wiring harness 423 to the recess 312 through the wiring harness assembly hole 324, improving the convenience of connecting the rear door wiring harness 5 and the spoiler wiring harness 423. Additionally, in special circumstances, tools such as a wire can be used to pull the spoiler wiring harness 423 out to the recess 312 through the wiring harness assembly hole 324 for inspection or maintenance. Optionally, the shape of the wiring harness assembly hole 324 can be square, circular, etc., and is not limited here. Furthermore, the wiring harness assembly hole 324 is provided with a cover, which is movably connected to the rear door panel 3, such as by rotation or sliding, to open or close the wiring harness assembly hole 324. Furthermore, the wire harness assembly hole 324 is provided in the recess 312, that is, located inside the sealing ring platform 311.

[0055] In one embodiment, refer to Figure 9 The tailgate assembly also includes a conduit 35. One end of the conduit 35 is connected to the spoiler 421, and the other end is connected to the sealing ring 311. The conduit 35 is sleeved on the outside of the spoiler wiring harness 423. Specifically, the conduit 35 can prevent the spoiler wiring harness 423 from directly contacting the edge of the wire passage notch 3141, avoiding friction damage to the wiring harness sheath. It also restricts the wiring harness from bending arbitrarily, extending the service life of the wiring harness. Furthermore, it can block rainwater, ultraviolet rays, and other substances from corroding the wiring harness, improving the wiring harness's waterproof and dustproof capabilities. Moreover, it can constrain the wiring harness's direction, preventing the wiring harness from becoming tangled, and further improving the flatness of the tailgate panel 3's appearance.

[0056] In one embodiment, refer to Figure 9 The outer periphery of the conduit 35 is provided with a sealing flange 351, which seals the wire harness through hole 323 and can improve the sealing performance of the wire harness through hole 323.

[0057] In one embodiment, refer to Figure 6 The rear door panel 3 has a mounting recess 315 on its surface, and the spoiler 421 is disposed in the mounting recess 315. Specifically, the mounting recess 315 can be used to position the spoiler 421 during assembly, and can also reduce the height of the spoiler 421 protruding from the rear door panel 3, thereby reducing wind resistance.

[0058] In one embodiment, refer to Figure 2The tailgate assembly also includes a decorative panel 6, which is located in a recess 312. The recess 312 and the decorative panel 6 cooperate to form a cavity, in which the tailgate wiring harness 5 is hidden. This reduces exposed wiring harnesses and further improves the cleanliness and consistency of the overall vehicle appearance. Optionally, the decorative panel 6 is detachably connected to the tailgate panel 3 for easy inspection and maintenance of the wiring harness. Furthermore, a mounting step is provided in the recess 312, and the decorative panel 6 abuts against the mounting step.

[0059] This application also proposes a vehicle body, referring to Figure 1 and Figure 2 The vehicle body includes: The vehicle body 1 has a receiving cavity 11 with an opening 12. It is understood that the vehicle body 1 is the frame structure of the vehicle body and is connected to the chassis. The receiving cavity 11 is what is commonly referred to as the trunk. The receiving cavity 11 has an opening 12 for installing the tailgate assembly. The vehicle body 1 has a mounting surface 13 facing the rear of the vehicle, which can be used to install hinges 2. The rear door assembly is rotatably disposed at the opening 12 to open or close the receiving cavity 11. It is understood that when the rear door assembly is open, the receiving cavity 11 can be placed or retrieved; when the rear door assembly is closed, the receiving cavity 11 is in a sealed state, and items cannot be retrieved. In this embodiment, the rear door assembly can be the rear door assembly described above, or it can be other forms of rear door assembly, which will not be detailed further; and Hinge 2, see reference Figure 11 The hinge 2 includes a fixed arm 21 and a rotating arm 22. The rotating arm 22 is rotatably connected to the fixed arm 21, and the fixed arm 21 is fixedly connected to the mounting surface 13. The end of the rotating arm 22 away from the fixed arm 21 is fixedly connected to the tailgate assembly. It can be understood that the hinge 2 achieves a rotatable connection between the tailgate assembly and the vehicle body 1, ensuring smooth rotation of the tailgate assembly. Specifically, the fixed arm 21 of the hinge 2 is fixedly connected to the vehicle body 1, and the rotating arm 22 of the hinge 2 is fixedly connected to the tailgate assembly. When the tailgate assembly rotates under external force, the rotating arm 22 rotates synchronously. Since the mounting surface 13 faces the rear of the vehicle, it can face the operator during installation, facilitating observation and improving assembly convenience.

[0060] In the technical solution adopted in this embodiment, the mounting surface 13 of the hinge 2 faces the rear of the vehicle. During the vehicle assembly process, when the operator installs the hinge 2, the installation position is directly facing the operator. There is no need to use auxiliary tools for blind installation, nor is it necessary to repeatedly adjust the operating posture. The operator can observe the installation process in real time and accurately, making the assembly process more convenient. This helps to shorten the vehicle assembly time and reduce manufacturing costs.

[0061] Furthermore, refer to Figure 11The vehicle body also includes a locking component 23, which is fixedly connected to the mounting surface 13 and the fixing arm 21. The locking direction of the locking component 23 is parallel to the length direction of the vehicle. Thus, when assembling the hinge 2, the operator can directly observe the installation position and the locking process of the locking component 23, further improving the convenience of the assembly operation. Optionally, the locking component 23 can be a bolt, rivet, etc. Connecting the vehicle body 1 and the fixing arm 21 with bolts is simple and convenient.

[0062] In one embodiment, the fixed arm 21 is provided with a first mounting hole, the extension direction of which is parallel to the length direction of the vehicle. Specifically, the vehicle body 1 is provided with a first mounting hole 131 that mates with the first mounting hole. The first mounting hole 131 extends along the length direction of the vehicle, the first mounting hole and the first mounting hole 131 are aligned, and are fixedly connected by a locking member 23. Optionally, the locking member 23 is a bolt, rivet, etc. Further, the first mounting hole 131 is a threaded hole. Connecting the vehicle body 1 and the fixed arm 21 with bolts is simple and convenient.

[0063] In one embodiment, two first mounting holes are provided, spaced apart along the width direction of the vehicle and symmetrically located on both sides of the connection position between the rotating arm 22 and the fixed arm 21. This improves the uniformity of force distribution on both sides of the rotating arm 22.

[0064] In one embodiment, the rotating arm 22 is fixedly connected to the side surface of the tailgate assembly facing the receiving cavity 11. It is understood that the rotating arm 22 is not fixed to the top wall of the tailgate assembly, but rather to the side surface of the tailgate assembly facing the receiving cavity 11. Thus, there is no need to reserve a mounting position for the hinge 2 in the thickness direction of the tailgate assembly, allowing the tailgate assembly to be made thinner, and the design of the recess 312 of the tailgate assembly to have greater flexibility.

[0065] In one embodiment, refer to Figure 1 The vehicle body 1 also has a limiting surface 14, which is adjacent to the mounting surface 13 and located below the rotating arm 22. The limiting surface 14 and the mounting surface 13 together form a rotation space in which the rotating arm 22 is rotatably positioned. It can be understood that the limiting surface 14 and the mounting surface 13 together form a rotation space, and the rotating arm 22 is rotatably positioned within this space, allowing the rotation path of the rotating arm 22 to be constrained. That is, when the tailgate panel 3 is closed, the rotating arm 22 rotates to the limiting surface 14 at most, at which point the tailgate panel 3 is completely closed. When the tailgate panel 3 is opened, the rotating arm 22 rotates away from the limiting surface 14.

[0066] In one embodiment, refer to Figure 11The rotating arm 22 includes a first segment 221, a second segment 222, and a third segment 223. One end of the first segment 221 is rotatably connected to the fixed arm 21, and the other end of the first segment 221 is bent and connected to one end of the second segment 222. The other end of the second segment 222 is bent and connected to the third segment 223. The third segment 223 is inclined away from the middle of the tailgate assembly, and the side surface of the tailgate assembly facing the receiving cavity 11 is fixedly connected to the third segment 223. In this way, the third segment 223 of the rotating arm 22 can extend close to the edge of the tailgate assembly, avoiding other structural components in the middle of the tailgate assembly. Moreover, the second segment 222 and the third segment 223 of the rotating arm 22 extend along the height direction of the vehicle, making the assembly and adjustment of the hinge 2 more convenient when applied to the recess 312 of tailgate assemblies of different sizes.

[0067] In one embodiment, the angle between the second segment 222 and the third segment 223 is an obtuse angle. Thus, the third segment 223 has a certain extension length in both the height and width directions of the vehicle, resulting in a good span in both the height and width directions of the mounting area between the third segment 223 and the tailgate assembly, thereby improving the torsional stiffness of the tailgate assembly.

[0068] In one embodiment, refer to Figure 11 The third section 223 is provided with a second mounting hole 2231. Multiple second mounting holes 2231 are provided at intervals. The multiple second mounting holes 2231 are staggered in both the height and width directions of the vehicle. In this way, the fixing points of the third section 223 and the tailgate assembly can be distributed in both the height and width directions of the vehicle, further improving the torsional stiffness of the tailgate assembly. Furthermore, the first segment 221, the second segment 222, and the third segment 223 are set as a single unit, which can improve the overall structural strength.

[0069] In one embodiment, the tailgate assembly is made of aluminum alloy, which is lightweight and can reduce the overall weight of the tailgate assembly. The tailgate assembly includes an outer panel 33 and an inner panel 34, at least one of which is made of aluminum alloy.

[0070] Furthermore, refer to Figure 3 The tailgate assembly is provided with a mounting protrusion 316, and the rotating arm 22 is fixedly connected to the mounting protrusion 316. In this way, the structural strength of the tailgate assembly at the hinge 2 mounting position can be improved, thereby ensuring the reliability of the connection between the tailgate assembly and the hinge 2 and improving the torsional stiffness of the tailgate assembly.

[0071] This invention also proposes a vehicle, which includes the body as described above. Specifically, the specific structure of the body refers to the above embodiments. Since the vehicle adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
