The tailgate inner panel includes a first mounting portion, a second mounting portion behind the first mounting portion, and a connecting plate connected between the first mounting portion and the second mounting portion. The connecting plate is inclined downward. The first spoiler is mounted on the first mounting portion and includes a main plate, a first vertical plate extending downward, and an extension plate extending rearward. The extension plate is connected with the connecting plate, such that the connecting plate, the extension plate and the first vertical plate collectively define a water collecting groove. First and second end portions of the water collecting groove are in communication with an external environment. The second spoiler is mounted on the second mounting portion and is provided with a convex rib forming a closed shape. The convex rib defines a dry area on the second mounting portion. When water in the external environment flows into the tailgate inner panel, the water collecting groove and the convex rib prevent the water from flowing into the dry area, avoiding the tailgate inner panel from being waterlogged and adversely affecting the vehicle.

Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to tailgate assemblies for vehicles. This application also relates to vehicles including such tailgate assemblies. Background Technology

[0002] A vehicle's tailgate assembly typically includes a tailgate body and a spoiler mounted on the tailgate body. The spoiler is used to improve the vehicle's aerodynamic performance.

[0003] In some vehicles, spoilers consist of a front spoiler and a rear spoiler assembled together. The front spoiler is positioned in front of the rear spoiler along the longitudinal direction of the vehicle, and there is a gap between the front and rear spoilers. This type of spoiler allows water from the outside environment to enter the space between the spoiler and the tailgate body through this gap, and may then enter other parts of the tailgate assembly through the operating holes on the tailgate body, causing water accumulation inside the tailgate assembly and thus adversely affecting the vehicle. Summary of the Invention

[0004] To address the aforementioned technical problems, a first aspect of this application proposes a tailgate assembly for a vehicle. The tailgate assembly includes an inner tailgate panel, a first mounting portion, a second mounting portion located rear of the first mounting portion along the longitudinal direction of the vehicle, and a connecting plate connecting the first and second mounting portions; the connecting plate is configured to slope downwards in a forward direction; a first spoiler is mounted on the first mounting portion; the first spoiler includes a main body plate, a first vertical plate extending downwards from the main body plate, and an extension plate extending rearwards from the first vertical plate; the extension plate is sealingly connected to the connecting plate such that the connecting plate, the extension plate, and the first vertical plate together define a water collection trough extending in the lateral direction of the vehicle, the water collection trough having a first end and a second end, both of which are in communication with the external environment; and a second spoiler is mounted on the second mounting portion and has a rib protruding towards the second mounting portion; the rib extends to form a closed shape and is adapted to make sealing contact with the second mounting portion to define a dry area on the second mounting portion.

[0005] In one embodiment, the water collection tank has a middle section located between a first end and a second end, and the height of the middle section is greater than the height of the first end and the height of the second end.

[0006] In one embodiment, the tailgate inner panel further includes a second vertical plate extending vertically downward from the connecting plate, and the second mounting portion is connected to the second vertical plate; a chamfer is formed between the end portion of the connecting plate in the lateral direction and the second vertical plate.

[0007] In one embodiment, the tilt angle of the connecting plate relative to the horizontal direction is between 2 and 5 degrees.

[0008] In one embodiment, the length of the connecting plate in the longitudinal direction is between 60 mm and 70 mm.

[0009] In one embodiment, a seal is provided between the second spoiler and the second mounting portion; the rib and the second mounting portion are in sealing contact with the seal.

[0010] In one embodiment, the second mounting portion is provided with two positioning pins, which are opposite each other in the lateral direction and protrude toward the second spoiler; the seal is provided with two positioning holes; the two positioning pins are adapted to be inserted into the corresponding positioning holes to position the seal on the second mounting portion.

[0011] In one embodiment, the second mounting portion is further provided with a positioning rib extending in the lateral direction; the seal is adapted to be disposed in front of the positioning rib in the longitudinal direction.

[0012] In one embodiment, the seal includes a cover portion and a mounting portion surrounding the cover portion; the mounting portion is adapted to be pressed between a rib and a second mounting portion to seal the gap between the rib and the second mounting portion; the cover portion is adapted to cover at least a portion of the dry area.

[0013] In one embodiment, the ribs define an enclosed area on the second spoiler; the second spoiler is also configured with support ribs within the enclosed area, the support ribs being adapted to press against the cover.

[0014] In one embodiment, the seal is made of foam board.

[0015] In one embodiment, the compression ratio of the foam board is greater than or equal to 50%.

[0016] In one embodiment, the second mounting portion further includes a wet area that is offset from the dry area; the wet area is spaced apart from the second spoiler to form a drainage channel between the second spoiler and the second mounting portion.

[0017] A second aspect of this application discloses a vehicle. This vehicle includes the tailgate assembly of the vehicle described above.

[0018] The beneficial effects of this application are as follows: In the tailgate assembly of the vehicle of this application, the connecting plate, the extension plate, and the first vertical plate jointly define a water collection channel extending in the lateral direction of the vehicle, and both ends of the water collection channel are in communication with the external environment. The ribs on the second spoiler define a dry area on the second mounting portion of the inner tailgate panel. When water from the external environment flows into the tailgate assembly, the water collection channel guides a portion of the water to drain from both ends of the water collection channel and substantially avoids the dry area. Water overflowing from the water collection channel and flowing backward is blocked by the ribs and cannot flow into the dry area. In this way, both the water collection channel and the ribs on the second spoiler are used to prevent water from flowing into the dry area, so that water will not flow into other parts of the tailgate assembly through the operating holes in the dry area, thereby avoiding water accumulation in the tailgate assembly and its adverse effects on the vehicle.

[0061] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] In this application, the directional term "front" refers to the direction generally pointing towards the front of the vehicle along the longitudinal direction, and the directional term "rear" refers to the direction generally pointing towards the rear of the vehicle along the longitudinal direction.

[0063] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Vehicle 1 includes a tailgate assembly 2. For example, the tailgate assembly serves as a trunk lid for the vehicle. Figure 2 As shown, the tailgate assembly 2 generally includes an inner tailgate panel 3 and a first spoiler 4 and a second spoiler 5 mounted on the inner tailgate panel 3. The second spoiler 5 is positioned behind and in contact with the first spoiler 4 along the longitudinal direction Y of the vehicle. During the vehicle's journey, the first spoiler 4 and the second spoiler 5 are used to improve the vehicle's aerodynamic performance.

[0064] The tailgate component 2 will now be described in detail.

[0065] like Figure 3 and Figure 4 As shown, the tailgate inner panel 3 includes a first mounting portion 31, a second mounting portion 32, and a connecting plate 33. The second mounting portion 32 is located behind the first mounting portion 31 along the longitudinal direction Y of the vehicle, and the connecting plate 33 connects the first mounting portion 31 and the second mounting portion 32. Also as... Figure 4 As shown, the first mounting portion 31, the second mounting portion 32, and the connecting plate 33 all extend generally along the lateral direction X of the vehicle. An operating hole 301 is formed on the second mounting portion 32. In some embodiments, the number of operating holes can be multiple. For example, some operating holes can be used for wiring harnesses and / or conduits to pass through, while others can be used for connecting the tailgate inner panel to the tailgate interior trim panel (not shown in the figure), without limitation.

[0066] The first spoiler 4 is mounted on the first mounting part 31, and the second spoiler 5 is mounted on the second mounting part 32. The mounting methods of the first spoiler 4 and the second spoiler 5 are well known to those skilled in the art and will not be described in detail here.

[0067] The connecting plate 33 is configured to slope downwards generally in a forward direction A. For example, the connecting plate 33 has a front edge 334 connected to the first mounting portion 31 and a rear edge 335 connected to the second mounting portion 32. The height of the rear edge 335 of the connecting plate is higher than the height of the front edge 334 of the connecting plate.

[0068] For example Figure 3 As shown, the first spoiler 4 includes a main body plate 42, a first vertical plate 41 extending downwards from the main body plate 42 generally along the vehicle's height direction Z, and an extension plate 43 extending rearwards from the first vertical plate 41. For example, the main body plate 42 has a rear edge 421. The first vertical plate 41 extends downwards from the rear edge 421 of the main body plate and extends in the lateral direction X. Viewed as a whole, the main body plate 42, the first vertical plate 41, and the extension plate 43 form a stepped shape.

[0069] After the first spoiler 4 is mounted onto the first mounting portion 31, the main body plate 42 covers the first mounting portion 31, and the extension plate 43 is sealed and fixedly connected to the connecting plate 33. For example, the extension plate 43 and the connecting plate 33 at least partially overlap, and an adhesive is applied between the overlapping portions of the extension plate 43 and the connecting plate 33, thereby sealing and bonding the extension plate 43 and the connecting plate 33 together. In this way, the connecting plate 33, the extension plate 43, and the first vertical plate 41 together define a water collection trough 20 extending in the lateral direction X of the vehicle. The water collection trough 20 has a first end 201 and a second end 202 opposite to each other in the lateral direction X (e.g., ...). Figure 5 As shown in the figure, both the first end 201 and the second end 202 are connected to the external environment.

[0070] Reference Figure 2 and Figure 3 After the second spoiler 5 is installed on the second mounting part 32, the second spoiler 5 contacts the main body plate 42 of the first spoiler 4. For example, the second spoiler 5 extends substantially forward beyond the connecting plate 33 and contacts the rear edge 421 of the main body plate 42 of the first spoiler 4. A gap 21 is formed between the second spoiler 5 and the rear edge 421 of the main body plate 42 of the first spoiler 4.

[0071] For reference Figure 3 and Figure 7The second spoiler 5 has a protruding rib 521 that extends toward the second mounting portion 32, and the rib 521 extends to form a closed shape (i.e., the rib 521 defines a closed area 522 on the second spoiler 5). After the second spoiler 5 is mounted onto the second mounting portion 32, the rib 521 makes a sealing contact with the second mounting portion 32, thereby defining a dry area 321 on the second mounting portion 32. The operating hole 301 on the tailgate inner panel 3 is located within the dry area 321. The area of ​​the dry area can be as large as possible to facilitate the provision of multiple operating holes within the dry area. The specific area of ​​the dry area can be determined according to the actual situation and is not limited here.

[0072] Water from the external environment enters the tailgate assembly 2 through the gap 21 between the first spoiler 4 and the second spoiler 5, and then collects in the water collection tank 20. Guided by the water collection tank 20, it flows in the lateral direction X, forming a first water flow B1. The first water flow B1 is eventually discharged from the first end 201 and / or the second end 202 of the water collection tank 20 (i.e., the first water flow B1 is discharged generally from both sides of the vehicle in the lateral direction X, and is substantially away from the dry area 321, such as...). Figure 5 As shown). After the water collection tank 20 is filled with water, a portion of the water still drains from the first end 201 and / or the second end 202 of the water collection tank 20 (i.e., forming the first water flow B1 mentioned above), while another portion of the water overflows from the water collection tank 20 and flows backward toward the dry area 321 behind the water collection tank 20, forming the second water flow B2 (as shown). Figure 5 (As shown). The second water flow B2 is blocked by the rib 521 and cannot enter the dry area 321, thus preventing leakage from the dry area 321. Specifically, the second water flow B2 flows generally rearward from the drainage channel 22 (see description below) and bypasses the dry area 321, eventually exiting from the rear of the vehicle. Thus, the ribs 521 on the water collection trough 20 and the second spoiler 5 both serve to prevent water entering the tailgate assembly 2 from flowing into the dry area 321, preventing water from flowing into other parts of the tailgate assembly 2 through the operating hole 301 in the dry area 321, avoiding water accumulation in the tailgate assembly 2 and its adverse effects on the vehicle. It should also be noted that since the water collection trough 20 guides some water to exit from the first end 201 and / or the second end 202 of the water collection trough 20, less water flows directly from the water collection trough 20 to the dry area 35, which helps to prevent water flowing to the dry area 35 from seeping into the dry area 321 and causing leakage in the dry area.

[0073] When there is little water entering the water collection tank 20 from the outside, the water will be guided by the water collection tank 20 and discharged only from the first end 201 and / or the second end 202 of the water collection tank 20, instead of overflowing from the water collection tank 20 and flowing to the dry area 321, thereby preventing water leakage in the dry area.

[0074] It should be understood that water remaining in the collection tank and / or drainage channel will gradually evaporate and dry.

[0075] In one embodiment, the tilt angle of the connecting plate 33 relative to the horizontal direction is between 2 and 5 degrees. Additionally, the length of the connecting plate 33 along the longitudinal direction Y is between 60 mm and 70 mm. This structure of the connecting plate 33 meets the vehicle's styling requirements and allows the water collection tank 20 to have a larger capacity, maximizing the drainage of water flowing into the water collection tank 20 from both ends (i.e., the first end 201 and the second end 202) and reducing the risk of leakage in dry areas. Of course, depending on the actual situation, the tilt angle of the connecting plate relative to the horizontal direction and / or the length along the longitudinal direction can also be other values, which will not be elaborated here.

[0076] like Figure 5 As shown, the water collection tank 20 has a central portion 203 located between the first end 201 and the second end 202. The height of the central portion 203 is greater than the height of the first end 201 and also greater than the height of the second end 202. For example, the water collection tank 20 is constructed in an arc shape with the central portion 202 generally convex upwards. In this way, water in the water collection tank 20 can automatically and smoothly drain from the first end 201 and / or the second end 202 of the water collection tank 20 under the action of gravity. The height difference between the central portion 203 and the first end 201, and the height difference between the central portion 203 and the second end 202, can be determined according to the actual situation and are not limited here.

[0077] like Figure 3 As shown, the tailgate inner panel 3 also includes a second vertical plate 34 extending vertically downward from the connecting plate 33. A second mounting portion 32 is connected to the second vertical plate 34. For example, the second vertical plate 32 extends vertically downward from the rear edge 335 of the connecting plate 33 and also generally extends in the lateral direction X. The front edge 323 of the second mounting portion 32 is connected to the lower edge 341 of the second vertical plate 34. Thus, the connecting plate 33, the second vertical plate 34, and the second mounting portion 32 generally form a stepped shape, and the front edge 323 of the second mounting portion 32 is lower than the rear edge 335 of the connecting plate 33.

[0078] Reference Figure 4 and Figure 6 The connecting plate 33 has two end portions along the lateral direction X (i.e., a first end portion 331 and a second end portion 332). A chamfer 333 is formed between the first end portion 331 and the second vertical plate 34, and similarly, a chamfer 333 is formed between the second end portion 332 and the second vertical plate 34. Thus, the water in the water collection tank 20 can also flow laterally and rearward under the guidance of the chamfer 333 and by inertia (i.e., forming a third water flow B3, such as...). Figure 5 (As shown) and drained, which can reduce or prevent water from flowing onto the rear door. It should be noted that the third water flow B3 is also largely off-center from the dry area 321 to avoid leakage in the dry area.

[0079] In one embodiment, such as Figure 4 and Figure 6 As shown, the chamfer 333 is generally triangular, and the width of the two chamfers 333 gradually increases in the direction away from each other (for example, for each triangular chamfer 333, a vertex and the opposite side of the vertex are generally distributed in the lateral direction X, and the vertex is close to the center of the vehicle, while the opposite side is close to the side of the vehicle). This chamfer helps to guide the water in the water collection tank 20 to drain in a laterally rearward direction. Of course, depending on the actual situation, the chamfer can also be constructed into other shapes, such as rectangles, etc., which are not limited here.

[0080] Reference Figure 3 and Figure 5 The second mounting portion 32 also includes a wet area 322 that is offset from the dry area 321. For example, the wet area 322 generally surrounds the dry area 321. After the second spoiler 5 is mounted on the second mounting portion 32, the wet area 322 is spaced apart from the second spoiler 5, thereby forming the drainage channel 22 described above between the second spoiler 5 and the second mounting portion 32. The drainage channel 22 extends generally rearward and communicates with the external environment. Water overflowing from the water collection tank 20 and flowing rearward (i.e., the second water flow B2) flows within the drainage channel 22 and bypasses the dry area 321, finally exiting the tailgate assembly 2 quickly rearward.

[0081] In one embodiment, such as Figure 3 As shown, the second spoiler 5 includes an outer plate 51 and an inner plate 52 assembled with the outer plate 51. The inner plate 52 faces the second mounting portion 32, and a rib 521 is formed on the inner plate 52. Thus, during the manufacture of the second spoiler, no injection molding marks corresponding to the ribs are formed on the outer surface of the second spoiler (i.e., the outer plate 51), which helps improve the appearance quality of the second spoiler. Of course, under appropriate circumstances, the ribs can also be formed directly on the outer plate. In this case, the second spoiler does not have an inner plate.

[0082] For example Figure 3 As shown, a seal 6 is provided between the second spoiler 5 and the second mounting portion 32. Both the rib 521 and the second mounting portion 32 are in sealing contact with the seal 6 to seal the gap between the rib 521 and the second mounting portion 32. The seal can be implemented as a plate shape that matches the closed area 522 defined by the rib 521, for example, made of foam board. Of course, in other embodiments, the seal can also be implemented in other shapes, such as an annular shape that matches the rib, and such a seal can be made of elastic rubber. The technical solution of this application will be described below using a plate-shaped seal as an example.

[0083] like Figure 3As shown, the seal 6 includes a cover portion 61 and a mounting portion 62 surrounding the cover portion 61 (i.e., the mounting portion 62 forms a circumferentially closed shape, and the cover portion 61 is located inside the mounting portion 62). Viewed as a whole, the shape of the seal 6 is substantially the same as the shape of the dry area 321. When the second spoiler 5 is mounted onto the second mounting portion 32, the mounting portion 62 is pressed between the rib 521 and the second mounting portion 32 to seal the gap between the rib 521 and the second mounting portion 32. The cover portion 61 covers and contacts at least a portion of the dry area 321, which also helps to prevent water from penetrating into the dry area 321.

[0084] For example Figure 8 As shown, the cover 61 is provided with an opening 612 corresponding to the operation hole 301 on the second mounting part 32, so as to facilitate the operator to assemble the wire harness, pipes, etc. mentioned above, and to prevent the seal 6 from being damaged.

[0085] like Figure 5 As shown, the second mounting section 32 has two locating pins 324 within the dry area 321. The two locating pins 324 are generally opposite each other in the lateral direction X and protrude towards the second spoiler 5. Figure 8 As shown, the cover portion 61 of the seal 6 has two positioning holes 611. When installing the second spoiler 5 onto the second mounting portion 32, the seal 6 is first placed onto the second mounting portion 32, and the two positioning pins 324 are inserted into the corresponding positioning holes 611 to pre-position the seal 6 on the second mounting portion 32. Then, the second spoiler 5 is installed onto the second mounting portion 32, and the ribs 521 on the second spoiler 5 press against the seal 6 (i.e., the ribs 521 press against the mounting portion 62 of the seal 6). During the installation of the second spoiler 5, the two positioning pins 324 constrain the seal 6, preventing the seal 6 from shifting, thereby accurately forming a dry area 321 at the predetermined position on the second mounting portion 32.

[0086] In other embodiments, the locating pin on the second mounting portion may be located outside the dry area. The seal also includes an outer portion of the mounting portion, in which a locating hole matching the locating pin is provided.

[0087] It should also be noted that the rib 521 of the second spoiler 5 only presses against the mounting portion 62, and the two are not fixedly connected. This allows for easy adjustment of the position of the second spoiler 5 as needed during installation, without requiring the seal 6 to be moved. This also helps to create a dry zone at the predetermined position of the second mounting portion 32. Alternatively, depending on the actual situation, the rib can be fixedly connected to the mounting portion of the seal (e.g., by bonding) during installation of the second spoiler, and the seal can be pressed against the second mounting portion.

[0088] Also refer to Figure 3 and Figure 5 The second mounting portion 32 is provided with a positioning rib 325 extending in the lateral direction X. For example, the positioning rib 325 is spaced apart from the second vertical plate 34 in the longitudinal direction Y and is located behind the second vertical plate 34. When the seal 6 is installed on the second mounting portion 32, the seal 6 is positioned in front of the positioning rib 325 in the longitudinal direction Y, and the positioning rib 325 provides a positioning reference for the seal 6 in the longitudinal direction Y. In this way, it can be ensured that the mounting portion 62 of the seal 6 is squeezed by the protruding rib 521 of the second spoiler 5, and that the cover portion 61 accurately covers the predetermined area on the second mounting portion 32, thereby forming a dry area at the predetermined position of the second mounting portion 32.

[0089] like Figure 7 As shown, the second spoiler 5 is also constructed with multiple support ribs 523 located within the enclosed area 522 defined by the protruding rib 521 on the second spoiler 5. These support ribs 523 can be connected to the protruding rib 521, or they can be spaced apart from the protruding rib 521. After the second spoiler 5 is installed on the second mounting part 32, these support ribs 523 also press against the cover part 61 of the seal 6, which helps to further improve the sealing effect of the seal 6.

[0090] In one embodiment, the rib has a mating plane (not shown) facing the second mounting portion. When the second spoiler is mounted onto the second mounting portion, the mating plane compresses the mounting portion of the seal. This helps to increase the contact area between the rib and the mounting portion of the seal, thereby helping to improve the sealing effect of the seal. In one embodiment, the width of the mating plane is between 12 mm and 15 mm. It should be understood that the width of the mating plane can also be set to other values ​​depending on the actual situation, and is not limited here. The same applies to the support rib, which will not be described further here.

[0091] In one embodiment, the foam board is made of EPDM (i.e., ethylene propylene diene monomer) foam. When the second spoiler is mounted onto the second mounting portion, the mounting portion is compressed by the protruding ribs on the second spoiler, causing the internal holes of the mounting portion to close, thereby achieving a sealing effect. This type of foam board has a low density, which does not significantly increase the weight of the tailgate assembly. Furthermore, this type of foam board is also low in cost, helping to reduce the cost of the tailgate assembly. Of course, those skilled in the art can use other materials to manufacture the foam board, which will not be elaborated here.

[0092] In one embodiment, the compression ratio of the foam board is greater than or equal to 50%. In this application, the compression ratio refers to the ratio of the reduction in thickness of the foam board when compressed to its original thickness before compression. For example, the thickness of the uncompressed foam board is 10 mm; after compression, the thickness is 5 mm or less. This ease of compression of the foam board effectively seals the gap between the rib and the second mounting portion. The protrusion of the rib toward the second mounting portion can be adjusted according to actual conditions to ensure sufficient compression of the mounting portion of the foam board. In one embodiment, the protrusion of the rib toward the second mounting portion is between 30 mm and 35 mm.

[0093] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
