Description

Technical Field

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

[0002] SUV (sport utility vehicle, or suburban utility vehicle) refers to a sport utility vehicle. Unlike ORV (off-road vehicle) which can be used on rough terrain, SUV is a type of vehicle that has the space and functionality of a station wagon, combined with the off-road capabilities of a truck.

[0003] SUVs have experienced rapid growth due to their advantages such as strong power, off-road capability, spaciousness, comfort, and excellent cargo and passenger carrying capacity. As SUVs have evolved, passengers have increasingly higher demands for the aesthetics and personalization of the rear styling, leading to a growing trend of tailgate interior trim panels.

[0004] In some embodiments, the tailgate of an SUV typically includes an outer panel, an inner panel, and a trim panel.

[0005] The outer panel is fixedly connected to the inner panel, and the inner panel is connected to the interior trim panel on the side away from the outer panel.

[0006] As the coverage of the interior trim panels increases on the side of the inner panel furthest from the outer panel, the number of mounting points on the inner panel for attaching with the trim panels also increases. Higher coverage also means greater weight for the interior trim panels, necessitating increased strength at the connections between the inner and outer panels. To enhance the strength of these connections, some embodiments incorporate reinforcing structures on the inner panel. These reinforcing structures provide stronger mounting points for the trim panels, increase the strength at the connections, and provide greater support to the inner panel, preventing deformation and consequently, deformation of the outer panel.

[0007] However, the increased number of mounting points on the inner panel increases the difficulty of molding it, and the added reinforcing structure further increases its weight, leading to higher processing costs. Furthermore, due to structural limitations, the inner panel struggles to provide sufficient support and positioning for larger interior trim panels, making installation difficult.

[0008] Therefore, how to provide a tailgate assembly for a vehicle that reduces the processing difficulty and cost of the inner panel is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0009] In view of the above problems, this application provides a tailgate assembly for a vehicle to reduce the processing difficulty and cost of the inner panel.

[0010] The specific plan is as follows:

[0011] The first aspect of this application provides a tailgate assembly for a vehicle, comprising:

[0012] Outer panel; inner panel, the inner panel being connected to the outer panel; support plate, the support plate being located at the hollowed-out position of the inner panel, and the support plate being connected to the inner panel at both ends along a first direction, and the support plate being connected to the outer panel at both ends along a second direction, the first direction being the width direction of the vehicle body, and the second direction being the height direction of the vehicle body; interior panel, the interior panel being used to connect to the support plate.

[0013] In one possible implementation, in the tailgate assembly of the vehicle described above, the support plate includes: a main body portion, both ends of which have overlapping surfaces for overlapping with the outer panel along the second direction; and a side portion, both ends of which have the side portion along the first direction, and the side portion having an overlapping surface for overlapping with the inner panel.

[0014] In one possible implementation, in the above-described tailgate assembly of the vehicle, the overlapping surface of the main body is connected to the outer panel; and / or, the overlapping surface of the side portion is connected to the inner panel.

[0015] In one possible implementation, in the aforementioned tailgate assembly of the vehicle, the overlapping surface of the side portion is an overlapping surface formed by a flange.

[0016] In one possible implementation, in the tailgate assembly of the vehicle described above, the main body has weight-reducing holes that are symmetrically arranged about the centerline of the main body along the second direction.

[0017] In one possible implementation, in the tailgate assembly of the vehicle described above, the support plate has interior panel mounting positioning holes for positioning and connecting with the interior panel and interior panel mounting holes for assembly and connecting with the interior panel; the interior panel mounting positioning holes and / or the interior panel mounting holes are symmetrically arranged about the centerline of the support plate along the second direction.

[0018] In one possible implementation, in the tailgate assembly of the vehicle described above, the support plate has positioning holes and / or mounting holes; the interior trim panel is used to cover the support plate.

[0019] In one possible implementation, in the tailgate assembly of the vehicle described above, the support plate is equipped with a wireless amplifier, and when the interior trim panel is installed on the support plate, the interior trim panel is able to block the wireless amplifier.

[0020] In one possible implementation, in the above-described tailgate assembly of the vehicle, the edge of the outer panel folds towards the inner panel to form a folded edge, and the folded edge wraps around the edge of the inner panel, the folded edge being connected to the edge of the inner panel.

[0021] A second aspect of this application provides a vehicle including a tailgate assembly, wherein the tailgate assembly is any one of the tailgate assemblies described above.

[0022] By employing the aforementioned technical solution, the tailgate assembly of the vehicle provided in this application incorporates a support plate, which is connected to both the inner and outer panels. The interior trim panel is then fixed to the support plate. This allows both the inner and outer panels to simultaneously provide support for the interior trim panel, distributing the stress on the inner panel and reducing the strength requirements for the connection between the inner and exterior trim panels. No additional reinforcing structure is needed, nor are mounting points for the interior trim panel required on the inner panel. This reduces the molding difficulty of the inner panel, thereby lowering the processing difficulty and cost. Furthermore, reducing the number of mounting points also reduces the weight of the inner panel. The support plate provides an effective fixing point for the interior trim panel, while simultaneously reducing the molding difficulty and improving customer satisfaction.

[0023] In addition, the support plate connects the inner and outer plates, thereby providing support for the outer plate and reducing the deformation rate of the inner and outer plates. Attached Figure Description

[0038] SUV (sport utility vehicle, or suburban utility vehicle) refers to a sport utility vehicle. Unlike ORV (off-road vehicle) which can be used on rough terrain, SUV is a type of vehicle that has the space and functionality of a station wagon, combined with the off-road capabilities of a truck.

[0039] SUVs have experienced rapid growth due to their advantages such as strong power, off-road capability, spaciousness, comfort, and excellent cargo and passenger carrying capacity. As SUVs have evolved, passengers have increasingly higher demands for the aesthetics and personalization of the rear styling, leading to a growing trend of tailgate interior trim panels.

[0040] The following combination Figure 1 The specific structure of the vehicle's tailgate is explained, including... Figure 1 This is the structure of the first type of vehicle tailgate disclosed in the embodiments of this application.

[0041] like Figure 1 The tailgate of the vehicle shown consists of an outer panel 100, an inner panel 200, and a interior trim panel 300.

[0042] The outer panel 100 and the inner panel 200 are stacked, optionally along the length of the vehicle body. The outer panel 100 and the inner panel 200 are fixedly connected, and the connection method includes, but is not limited to, welding, threaded connection, or snap-fit. For the connection method between the inner panel 200 and the outer panel 100, refer to the connection method of existing vehicles, which will not be specifically described here. In some embodiments, both the outer panel 100 and the inner panel 200 may be sheet metal parts. Both the outer panel 100 and the inner panel 200 have through holes for installing the glass of the tailgate to form the window glass on the tailgate. The shape and size of the window glass on the tailgate can be set according to different needs, and all are within the protection range.

[0043] The inner panel 200 is connected to the side away from the outer panel 100 by an interior trim panel 300. The shape and size of the interior trim panel 300 can be set according to different needs. In some embodiments, the material of the interior trim panel 300 can be injection molded and the surface is covered with fabric.

[0044] In some embodiments, the interior trim panel 300 and the inner panel 200 are fixedly connected, and the connection method between the two includes, but is not limited to, snap-fit. For example, the inner panel 200 has a connecting buckle on the side near the interior trim panel 300, and the interior trim panel 300 has a slot on the side near the inner panel 200 that can engage with the connecting buckle.

[0045] As the coverage of the interior panel 300 increases on the side of the inner panel 200 furthest from the outer panel 100, the number of mounting points on the inner panel 200 for installation with the interior panel 300 increases. The higher the coverage of the interior panel 300, the greater its weight, necessitating increased strength at the connection between the inner and outer panels 200. To improve the strength at the connection between the inner and outer panels 200, some embodiments incorporate a reinforcing structure on the inner panel 200. This reinforcing structure provides stronger mounting points for the interior panel 300, increases the strength at the connection, and provides greater support for the inner panel 200, preventing deformation and consequently preventing deformation of the outer panel 100.

[0046] However, the increased number of mounting points on the inner panel 200 increases the difficulty of molding it, and the added reinforcing structure further increases its weight, leading to higher processing costs. Furthermore, due to structural limitations, the inner panel 200 struggles to provide sufficient support and positioning for the larger interior trim panel 300, making its installation difficult.

[0047] Based on the aforementioned technical problems, in this application Figures 2 to 7 The invention also discloses a tailgate assembly for a vehicle. By adding a support plate, the support plate is connected to both the inner panel 200 and the outer panel 100, and the interior trim panel 300 is installed on the support plate. This eliminates the need to set multiple mounting points for the interior trim panel 300 on the inner panel 200, and also eliminates the need to add a reinforcing frame to the inner panel 200. It can be understood that the improvement to the inner panel 200 is relatively small, which reduces the molding difficulty of the inner panel 200, reduces the weight of the inner panel 200, and reduces the processing difficulty and processing cost of the inner panel 200.

[0048] in, Figure 2 This is a partial structural diagram of the tailgate of a second type of vehicle provided in an embodiment of this application.

[0049] like Figure 2 The tailgate of the vehicle shown consists of an outer panel 100, an inner panel 200, and a support panel 400.

[0050] Among them, Figure 2 In the middle, the inner panel 200 has a cutout position, and only part of the outer panel 100 can be exposed through the cutout position, while the other parts of the outer panel 100 are covered by the inner panel 200. Figure 3 The shape of the outer panel 100, inner panel 200 and support plate 400 is shown in the figure. The specific shape of the outer panel 100, inner panel 200 and support plate 400 is not limited.

[0051] from Figure 2As can be seen, the support plate 400 is located at the hollowed-out position, and both ends of the support plate 400 along the first direction are fixedly connected to the inner plate 200, and both ends of the support plate 400 along the second direction are fixedly connected to... Figure 3 The outer panel 100 is fixedly connected to the support plate 400. It should be noted that the first direction in this article refers to the width direction of the vehicle body, and the second direction refers to the height direction of the vehicle body. The connection methods between the support plate 400 and the inner panel 200 include, but are not limited to, welding, snap-fit, or threaded connections. The connection methods between the support plate 400 and the outer panel 100 include, but are not limited to, welding, snap-fit, or threaded connections.

[0052] Combination Figure 3 As shown, where Figure 3 for Figure 2 A cross-sectional view along the AA direction.

[0053] In this application, the first side 4011 and the second side 4012 of the support plate 400 are both fixedly connected to the outer plate 100. Specifically, the first side 4011 and the second side 4012 of the support plate 400 are welded to the outer plate 100. Furthermore, the outer plate 100 is welded to the inner plate 200. It should be noted that the first side 4011 and the outer plate 100, and the second side 4012 and the outer plate 100, can also be connected by snap-fit ​​or threaded connection.

[0054] In some embodiments, the end of the outer panel 100 is connected to the inner panel 200 by an edge banding. Specifically, the end of the outer panel 100 has a flange that wraps around the inner panel 200 to form a pre-fixed edge banding. The pre-fixed edge banding method ensures the stability of the connection between the outer panel 100 and the inner panel 200, and also ensures the sealing of the connection between the inner panel 200 and the outer panel 100.

[0055] The following combination Figures 4 to 7 The shape of the support plate 400 and its connection relationship with the inner plate 200 and the outer plate 100 are described. Figure 4 A schematic diagram of the structure of the support plate for the tailgate of the second type of vehicle provided in this application embodiment; Figure 5 A front view of the support plate comprising the tailgate of a second type of vehicle provided in an embodiment of this application; Figure 6 for Figure 5 Cross-sectional view along the BB direction; Figure 7 for Figure 5 A cross-sectional view along the CC direction.

[0056] like Figure 4 and Figure 5 As shown, the support plate 400 includes a main body 401 and a side part 402.

[0057] The main body 401 has side portions 402 at both ends along the first direction. The main body 401 and the side portions 402 are, but are not limited to, integrally formed structural components. In some embodiments, the two side portions 402 can be symmetrical about the main body 401 to ensure that the inner plate 200 adapts to the symmetrical structure.

[0058] The main body 401 has a first side 4011 and a second side 4012 at its two ends along the second direction, which are combined with Figure 3 and Figure 6 It is known that the first side 4011 and the second side 4012 are respectively welded to the outer plate 100. In some embodiments, the main body 401 is a conformal structure that follows the shape of the outer plate 100, the first side 4011 has an undulating shape and is used to form an overlapping surface that overlaps with the outer plate 100. For example, the overlapping surfaces of the first side 4011 that overlap with the outer plate 100 include, but are not limited to, six. By welding the overlapping surfaces of the first side 4011 to the outer plate 100, a fixed connection between the first side 4011 and the outer plate 100 is achieved.

[0059] It should be noted that, in order to ensure the stability of the connection between the first side 4011 and the outer panel 100, the overlapping surface of the first side 4011 is adapted to the surface of the outer panel 100 to form a bonding surface structure with a large contact area.

[0060] In some embodiments, the main body 401 has multiple weight-reducing holes 403. The shape, size, position, and number of the weight-reducing holes 403 can be set according to different needs, and all are within the protection range. For example, a weight-reducing hole 403 is provided at the middle position of the main body 401, and the weight-reducing hole 403 is preferably symmetrical to ensure that the center of gravity of the support plate 400 is as close as possible to the center of the support plate 400, so as to avoid uneven force on both ends of the support plate 400 after installation, which would cause the inner plate 200 to be easily deformed. Other weight-reducing holes 403 are respectively provided at both ends of the weight-reducing hole 403 at the middle position of the main body 401 along the first direction to further reduce the weight of the support plate 400.

[0061] It should be noted that the position and shape of the weight reduction hole 403 on the support plate 400 are preferably symmetrical about the center line of the support plate 400 along the second direction.

[0062] Combination Figure 4 , Figure 5 and Figure 7 It can be seen that the side portion 402 and the main body portion 401 are not on the same plane. It can be understood that the side portion 402 is higher than the plane where the main body portion 401 is located (the plane formed by the first direction and the second direction). The shape and trend of the side portion 402 and the main body portion 401 are related to the shape and trend of the inner plate 200. In some embodiments, the side portion 402 is a conformal structure that follows the shape of the inner plate 200.

[0063] Depend on Figure 2 It can be seen that the two side portions 402 are respectively fixed to the inner plate 200, and the side portions 402 and the inner plate 200 are connected by welding, including but not limited to welding.

[0064] Both ends of the side portion 402 along the second direction and the end along the first direction away from the main body portion 401 have flanges 4021. The flanges 4021 form an overlapping surface with the inner plate 200. The connection between the side portion 402 and the inner plate 200 is achieved by welding the overlapping surface to the inner plate. By providing multiple flanges 4021, the contact area between the side portion 402 and the inner plate 200 is increased, ensuring the stability of the connection.

[0065] The angle and size of the 4021 flange can be set according to different needs, and all are within the protection range.

[0066] The above discloses the substrate structure of the support plate 400, as well as the connection method and connection position of the support plate 400, the inner plate 200 and the outer plate 100. The following describes the connection between the support plate 400 and the interior panel 300. Figures 2 to 7 (The connection method is not shown in the image).

[0067] like Figure 4 and Figure 5 As shown, the support plate 400 has interior panel mounting positioning holes 404 and interior panel mounting holes 405.

[0068] For example, the interior panel mounting positioning hole 404 is located on the main body 401 and near the side part 402. The interior panel mounting positioning hole 404 is symmetrically arranged on the main body 401 about the center line of the main body 401 in the second direction to ensure the accuracy of the position of the interior panel 300 during the installation of the interior panel 300 on the support plate 400.

[0069] Multiple interior panel mounting positioning holes 404 are arranged along the second direction. The shape of the interior panel mounting positioning holes 404 includes, but is not limited to, round holes, oblong holes or rectangular holes. The number and setting position of the interior panel mounting positioning holes 404 can be set according to the shape and size of the interior panel 300.

[0070] The interior panel mounting holes 405 are symmetrically arranged about the centerline of the main body 401 in the second direction to ensure the stability of the interior panel 300 supported in the first direction. The number and specific position of the interior panel mounting holes 405 can be set according to the shape and size of the interior panel 300. This application does not specifically limit them, as long as the interior panel 300 is fixed to the support plate 400.

[0071] As the above analysis shows, the tailgate assembly of the vehicle in this application incorporates a support plate 400, which is welded to the inner panel 200 and the outer panel 100. The interior trim panel 300 is then fixed to the support plate 400. This allows the inner panel 200 and the outer panel 100 to simultaneously provide support for the interior trim panel 300, distributing the stress on the inner panel 200 and reducing the strength requirements when connecting it to the interior trim panel 300. No additional reinforcing structure is needed, nor are mounting points for the interior trim panel 300 required on the inner panel 200. This reduces the molding difficulty and weight of the inner panel 200, thereby lowering the processing difficulty and cost. The support plate 400 provides an effective fixing point for the interior trim panel 300, while also reducing the molding difficulty of the inner panel 200, thus improving customer satisfaction.

[0072] In addition, the support plate 400 connects the inner plate 200 and the outer plate 100, thereby providing support for the outer plate 100 and reducing the deformation rate of the inner plate 200 and the outer plate 100.

[0073] In some embodiments, Figure 5 The support plate 400 is also provided with positioning holes 406 and mounting holes 407. Optionally, the positioning holes 406 and mounting holes 407 can be used to install a wireless amplifier. It can be understood that, in some embodiments, the wireless amplifier is mounted on the support plate 400 through the positioning holes 406 and mounting holes 407. The mounting position of the wireless amplifier on the support plate 400 can be set according to different needs, and the wireless amplifier and the support plate 400 can also be connected by adhesive, snap-fit ​​or threaded connection.

[0074] A vehicle wireless amplifier is a device specifically designed to enhance the reception and transmission of wireless signals within a vehicle. It improves the signal quality of wireless devices inside the car, ensuring stable signal reception in various environments. Specifically, the main functions of a wireless amplifier include: receiving external signals: capturing external signals through a receiving antenna on the roof, processing them through the main unit, and then transmitting the signal into the vehicle through an indoor antenna, allowing users to clearly use wireless devices such as radios and car phones inside the car.

[0075] By mounting the wireless amplifier on the support plate 400 and using the interior panel 300 to cover the wireless amplifier, the wireless amplifier can be installed in a concealed manner, ensuring its safety and preventing collisions. In addition, it can also ensure the consistency and aesthetics of the vehicle's tailgate appearance.

[0076] In some embodiments, Figure 5 The support plate 400 is also provided with wire harness mounting holes 408 for threading wire harnesses of electronic components, including but not limited to cameras.

[0077] Based on the structure of the tailgate of the vehicle described above, the overall assembly process of the tailgate assembly is explained below:

[0078] The mounting nuts of the wireless amplifier are riveted into the positioning holes 406 and mounting holes 407 of the support plate 400 to install the wireless amplifier and the support plate 400, forming the tailgate interior reinforcement plate assembly.

[0079] The two side portions 402 of the support plate 400 of the tailgate interior reinforcement panel assembly are welded to the inner panel 200 to form the tailgate inner panel assembly.

[0080] The inner panel 200 and outer panel 100 of the tailgate inner panel assembly are pre-fixed by edge binding, and then the first side 4011 and the second side 4012 of the support plate 400 are welded to the outer panel 100 to form the tailgate assembly.

[0081] Next, install the tailgate assembly onto the body-in-white, complete the electrophoretic coating, and then assemble all the assembly parts in the final assembly.

[0082] It should be noted that the tailgate components of the vehicles mentioned in this article include not only steel tailgates, but also tailgates made of aluminum or plastic.

[0083] In addition, this application also discloses a vehicle including a tailgate assembly, wherein the tailgate assembly is the tailgate assembly disclosed in the above embodiments. Therefore, the vehicle having the tailgate assembly also has all the above-mentioned technical effects, which will not be described in detail here.

[0084] It should be noted that the vehicles mentioned in this application include, but are not limited to, SUVs, and other vehicles with tailgates are also within the scope of protection.

[0085] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
