Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicles, and in particular to a rear wing spoiler assembly, a tailgate and a vehicle. Background Art

[0002] The spoiler is an additional plate installed at the rear of the vehicle. It not only makes the appearance of the vehicle more beautiful, but also can effectively reduce the buoyancy of the vehicle during driving, saving fuel while improving the stability of the vehicle. At present, high-end models are usually equipped with plastic spoilers. The spoiler is connected to the rear wing movement mechanism, and the rear wing movement mechanism is used to absorb the dimensional changes of the spoiler due to thermal expansion and contraction. Since low-end models do not have a rear wing movement mechanism, they can only use sheet metal spoilers to reduce the dimensional changes of the spoiler due to thermal expansion and contraction. This results in the spoilers of vehicles with different configurations not being universal, and the corresponding molds used to form the spoilers are also not universal, which leads to higher manufacturing costs for the vehicles.

[0045] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0046] The present disclosure is based on the inventor's discovery and understanding of the following facts and problems:

[0047] When the size of the spoiler assembly changes due to thermal expansion and contraction, it will make it difficult to match the appearance of the spoiler assembly with other parts, affecting the appearance of the entire vehicle. For high-end models with a rear wing movement mechanism, the spoiler assembly is directly connected to the rear wing movement mechanism with fasteners. The change in the gap of the rear wing movement mechanism itself can offset the appearance mismatch caused by the size change of the spoiler assembly. For low-end models without a rear wing movement mechanism, if the same spoiler assembly is to be used with the high-end model, the spoiler assembly needs to be directly connected to the rear door body with fasteners, which requires consideration of how to solve the appearance mismatch caused by the size change of the spoiler assembly.

[0048] like Figures 1 to 8 As shown, the rear spoiler assembly 10 of the disclosed embodiment includes a spoiler 1, a mounting frame 2 and a fastener 3. The mounting frame 2 is connected to the spoiler 1, and the mounting frame 2 is provided with a connecting hole 221. Figures 9 to 11 As shown, the fastener 3 passes through the connection hole 221 and is connected to the back door body. The mounting frame 2 can move relative to the fastener 3 along a first preset direction; the first preset direction is perpendicular to the axial direction of the connection hole 221.

[0049] The rear wing spoiler assembly 10 of the disclosed embodiment, when the spoiler 1 is used for a low-end vehicle model, the fastener 3 is passed through the connection hole 221 of the mounting frame 2, and the fastener 3 is connected to the back door body, so that the spoiler 1 is connected to the back door body through the mounting frame 2. When the spoiler 1 changes in size due to thermal expansion and contraction, the mounting frame 2 can be moved relative to the fastener 3 along the first preset direction, that is, the spoiler 1 is driven to move, so that the spoiler 1 remains in a state of matching with other parts. When the spoiler 1 is used for a high-end vehicle model, the mounting frame is directly connected to the rear wing motion mechanism of the back door body. As a result, the spoiler 1 can be used not only for low-end vehicles, but also for high-end vehicles, so that the spoiler of the low-end vehicle model and the spoiler of the high-end vehicle model can be manufactured using the same set of molds, thereby reducing the manufacturing cost of the vehicle.

[0050] Alternatively, if Figure 3 and Figure 7 As shown, there are multiple connection holes 221 and fasteners 3, and the fasteners 3 correspond to the connection holes 221. The multiple connection holes 221 are arranged at intervals along the second preset direction, and the second preset direction is perpendicular to the axial direction of the connection holes 221 and the first preset direction.

[0051] For example, the number of the connecting holes 221 and the fasteners 3 is two, the two fasteners 3 correspond to the two connecting holes 221 one by one, and each fastener 3 passes through the corresponding connecting hole 221 and is connected to the tailgate body.

[0052] By setting the number of the connection holes 221 and the fasteners 3 to be multiple, the connection between the spoiler assembly 10 and the tailgate body is achieved through multiple fasteners 3, which can improve the connection reliability between the spoiler assembly 10 and the tailgate body.

[0053] The X direction is the length direction of the spoiler 1; the Y direction is the width direction of the spoiler 1; and the Z direction is the axial direction of the connecting hole 221. The first preset direction and the second preset direction can be any two mutually perpendicular directions in the XY plane. For example, the first preset direction is the length direction of the spoiler 1, and the second preset direction is the width direction of the spoiler 1. The X direction, the Y direction, and the Z direction are as follows: Figures 1 to 3 , Figure 7 , Figures 9 to 11 shown.

[0054] For example, the connection hole 221 is a long strip hole extending along the length direction of the spoiler 1, so that the spoiler 1 can be relatively fastened to the fastener 3 along its length direction. A plurality of connection holes 221 are arranged at intervals along the width direction of the spoiler 1.

[0055] Optionally, the spoiler 1 is a plastic spoiler, the mounting frame 2 is a metal frame, and the mounting frame 2 and the spoiler 1 are integrally injection molded.

[0056] By setting the spoiler 1 as a plastic spoiler, the cost of the spoiler assembly 10 can be reduced while reducing the weight of the spoiler assembly 10. By setting the mounting frame 2 as a metal frame, it is beneficial to improve the structural strength of the mounting frame 2, thereby improving the connection reliability between the mounting frame 2 and the fastener 3, and further improving the connection reliability between the spoiler assembly 10 and the rear door body. In addition, the mounting frame 2 and the spoiler 1 are integrally injection molded, which not only helps to reduce the number of parts of the spoiler assembly 10 and improve the assembly efficiency of the spoiler assembly 10; it also facilitates the processing and manufacturing of the spoiler assembly 10 and reduces the manufacturing cost of the spoiler assembly 10.

[0057] In some embodiments, Figure 3 and Figure 4 As shown, the fastener 3 includes a screw rod 31 and a bolt head 32 . The bolt head 32 is connected to one end of the screw rod 31 . The bolt head 32 abuts against the mounting bracket 2 . The screw rod 31 is cantilevered to be connected to the tailgate body.

[0058] like Fig.12As shown, the tailgate body 20 is provided with a fixing hole 201, and the screw 31 passes through the fixing hole 201 and is connected with the nut 4, so that the mounting frame 2 and the tailgate body 20 are clamped between the bolt head 32 and the nut 4, so as to realize the connection between the tailgate body 20 and the spoiler assembly 10, that is, the spoiler assembly 10 is installed on the tailgate. A gasket 5 can be arranged between the nut 4 and the mounting frame 2.

[0059] By configuring the fastener 3 to include a screw rod 31 and a bolt head 32 , the spoiler assembly 10 and the rear door can be disassembled, thereby facilitating replacement of the spoiler assembly 10 .

[0060] Alternatively, if Figures 4 to 6 As shown, the bolt head 32 includes a stop portion 321 and a neck portion 322, the neck portion 322 is connected to the screw rod 31, and the stop portion 321 is arranged on a side of the neck portion 322 away from the screw rod 31 and connected to the neck portion 322. The cross-sectional area of ​​the neck portion 322 is smaller than the cross-sectional area of ​​the stop portion 321, the neck portion 322 is inserted into the connection hole 221, and the stop portion 321 stops at the mounting frame 2.

[0061] The cross-sectional area of ​​the neck 322 refers to the cross-sectional area of ​​the neck 322 cut by a plane perpendicular to the length direction of the screw 31 . The cross-sectional area of ​​the stop portion 321 refers to the cross-sectional area of ​​the stop portion 321 cut by a plane perpendicular to the length direction of the screw 31 .

[0062] By setting the fastener 3 to the above structure, when installing the spoiler assembly 10, the neck 322 can be inserted into the connecting hole 221 first, and the mounting frame 2 can be clamped between the stop portion 321 and the screw 31 to achieve pre-fixation between the fastener 3 and the mounting frame 2 to prevent the fastener 3 from being separated from the mounting frame 2; then, the screw 31 is inserted into the fixing hole 201 of the rear door body 20. In this way, the installation and fixation of the spoiler assembly 10 is facilitated, which is conducive to improving the installation efficiency of the spoiler assembly 10.

[0063] Optionally, in the second preset direction, the size of the neck 322 is smaller than the size of the connecting hole 221 , so that the mounting bracket 2 can move relative to the neck 322 along the first preset direction.

[0064] For example, in the width direction of the spoiler 1 , the size of the neck 322 is smaller than the size of the connecting hole 221 , thereby preventing the hole wall of the connecting hole 221 from restricting the movement of the neck 322 , so that the mounting frame 2 can move relative to the neck 322 along the length direction of the spoiler 1 .

[0065] By designing the dimensions of the neck 322 and the connecting hole 221 as above, it is convenient to realize that the mounting frame 2 moves relative to the neck 322 along the first preset direction.

[0066] Alternatively, if Figures 4 to 6 As shown, the fastener 3 further includes a stopper 33, which is disposed between the neck 322 and the screw rod 31 and connected to the screw rod 31. The cross-sectional area of ​​the stopper 33 is greater than the cross-sectional area of ​​the neck 322. The mounting frame 2 is clamped between the bolt head 32 and the stopper 33.

[0067] The cross-sectional area of ​​the stopper 33 refers to the cross-sectional area of ​​the stopper 33 cut by a plane perpendicular to the length direction of the screw rod 31 .

[0068] By setting the fastener 3 to the above-mentioned structure, when installing the rear wing spoiler assembly 10, the mounting frame 2 is clamped between the stop portion 321 and the limit block 33, thereby improving the limit reliability between the fastener 3 and the mounting frame 2, and more effectively avoiding the fastener 3 from separating from the mounting frame 2, which is beneficial to improving the installation efficiency of the rear wing spoiler assembly 10.

[0069] Alternatively, if Figures 4 to 6 As shown, the fastener 3 includes an insert rod 34, which is embedded in the bolt head 32, and the screw rod 31, the limit block 33 and the insert rod 34 are integrally formed.

[0070] By embedding the insertion rod 34 in the bolt head 32 and integrally forming the screw rod 31 , the limit block 33 and the insertion rod 34 , the connection reliability of the various parts of the fastener 3 is improved, and the connection reliability of the spoiler 1 and the tailgate is improved.

[0071] Alternatively, if Figure 7 and Figure 8 As shown, the mounting frame 2 is provided with a through hole 222 , which is communicated with the connecting hole 221 , and the through hole 222 is for the bolt head 32 to pass through.

[0072] It is understandable that the cross-sectional area of ​​the bolt head 32 is larger than the cross-sectional area of ​​the connecting hole 221, and it is difficult for the bolt head 32 to directly penetrate the connecting hole 221. By providing the through hole 222 for the bolt head 32 to penetrate, when installing the spoiler assembly 10, the bolt head 32 can first pass through the through hole 222, and then move toward the connecting hole 221 into the connecting hole 221, further facilitating the installation and fixation of the spoiler assembly 10, and improving the installation efficiency of the spoiler assembly 10.

[0073] Of course, in other embodiments, the bolt head 32 may be cooled first to reduce its cross-sectional area before passing through the connecting hole 221 .

[0074] In some embodiments, the bolt head 32 and the limiting block 33 are both plastic parts.

[0075] By making the bolt head 32 and the limit block 33 both plastic parts, it is possible to avoid abnormal noise caused by friction between the bolt head 32 and the limit block 33 and the mounting frame 2 when the mounting frame 2 moves relative to the fastener 3, which is beneficial to reducing the operating noise of the rear wing spoiler assembly 10.

[0076] In some other embodiments, at least one of the bolt head 32 and the limiting block 33 is a metal component, and a first plastic layer 35 is provided on the outer side of the metal component.

[0077] For example, Figure 6 As shown, the bolt head 32 is a plastic part, the limiting block 33 is a metal part, and the outer side of the limiting block 33 is covered with a plastic layer 35 .

[0078] By providing a plastic layer 35 on the outside of the metal part, it is possible to avoid abnormal noise caused by friction between the bolt head 32 and the limit block 33 and the mounting frame 2 when the mounting frame 2 moves relative to the fastener 3, which is beneficial to reducing the operating noise of the rear wing spoiler assembly 10.

[0079] Alternatively, if Figure 6 As shown, the screw rod 31, the stopper 33 and the insert rod 34 are all metal parts, and the screw rod 31, the stopper 33 and the insert rod 34 are integrally formed. The bolt head 32 is a plastic part, and the bolt head 32 and the plastic layer 35 are integrally formed. Among them, the fastener 3 is integrally injection molded.

[0080] Therefore, the processing and manufacturing of the fastener 3 is facilitated, which is beneficial to further reduce the manufacturing cost of the rear wing spoiler assembly 10.

[0081] Optionally, the insertion rod 34 is provided with an injection molding groove, and the injection molding groove is filled with a plastic layer 35 .

[0082] By providing an injection molding groove on the insertion rod 34 and filling the injection molding groove with a plastic layer 35 , it is beneficial to increase the connection area between the insertion rod 34 and the plastic layer 35 , and improve the connection reliability between the plastic layer 35 and the insertion rod 34 , thereby helping to further improve the reliability of the rear wing spoiler assembly 10 .

[0083] Alternatively, if Figures 4 to 6 As shown, a sealing member 36 is provided on a side of the neck 322 away from the stop portion 321 , and the sealing member 36 blocks the connecting hole 221 .

[0084] By providing the sealing member 36 to seal the connection hole 221 , it is possible to prevent moisture, dust, etc. from entering the rear wing spoiler assembly 10 through the connection hole 221 and causing corrosion of the mounting frame 2 , etc., which is beneficial to further improve the reliability of the rear wing spoiler assembly 10 .

[0085] Optionally, the sealing member 36 is a flexible plastic layer, and a skirt 361 is provided on a side of the sealing member 36 facing away from the bolt head 32 .

[0086] like Fig.12 As shown, when the fastener 3 is connected to the rear door body 20, the skirt 361 stops at the rear door body 20, thereby preventing water vapor, dust, etc. from entering between the rear door body 20 and the mounting frame 2 through the fixing hole 201, further improving the reliability of the rear wing spoiler assembly 10.

[0087] Alternatively, if Figure 3 and Figure 4 As shown, the mounting frame 2 includes a fixing portion 21 and a connecting portion 22, wherein the fixing portion 21 is connected to the spoiler 1. A connecting hole 221 is provided in the connecting portion 22, and the connecting portion 22 and at least a portion of the spoiler 1 are spaced apart along the axial direction of the connecting hole 221 to enclose an accommodating cavity 101 for accommodating the bolt head 32.

[0088] For example, Figure 4 As shown, the bolt head 32 is arranged in the accommodating cavity 101 .

[0089] By arranging the bolt head 32 in the accommodating cavity 101 , the fastener 3 can be prevented from being exposed to the outside, which not only improves the safety of the fastener 3 but also improves the appearance of the rear wing spoiler assembly 10 .

[0090] Alternatively, if Figure 3 As shown, the spoiler 1 is provided with a groove 13 , the connecting portion 22 blocks the notch of the groove 13 , and an accommodating cavity 101 is formed between the connecting portion 22 and the groove wall of the groove 13 .

[0091] By providing the groove 13 on the spoiler 1 and forming the accommodating cavity 101 between the connecting portion 22 and the groove wall of the groove 13, the structural compactness of the spoiler assembly 10 is improved, thereby facilitating the reduction of the volume of the spoiler assembly 10 and the cost of the spoiler assembly 10.

[0092] Alternatively, if Figure 3 and Figure 4 As shown, the spoiler 1 includes a first plate body 11 and a second plate body 12 arranged in a stacked manner, with a gap between the first plate body 11 and the second plate body 12. The fixing portion 21 is connected to the first plate body 11, and the first plate body 11 is provided with a through hole 111. The hole wall of the through hole 111 and the second plate body 12 form a groove 13, and the hole wall of the through hole 111, the second plate body 12 and the connecting portion 22 form a receiving cavity 101. Among them, the surface of the second plate body 12 facing away from the first plate body 11 is the appearance surface.

[0093] By configuring the spoiler 1 to include a first plate body 11 and a second plate body 12, and a gap is provided between the first plate body 11 and the second plate body 12, the middle of the spoiler 1 is a hollow structure, which saves materials and helps to reduce the weight of the spoiler 1. In addition, by configuring the through hole 111 in the first plate body 11, and using the hole wall of the through hole 111 and the second plate body 12 to form a groove 13, the processing and manufacturing of the spoiler 1 is facilitated, which helps to reduce the cost of the rear spoiler assembly 10.

[0094] Alternatively, if Figure 3 and Figure 4 As shown, the connecting portion 22 is protruded relative to the fixing portion 21 in a direction away from the second plate body 12 .

[0095] As a result, the distance between the connecting portion 22 and the second plate body 12 is larger, so that the space of the accommodating cavity 101 is larger, so as to provide sufficient accommodating space for the bolt head 32 .

[0096] Optionally, the fixing portion 21 is annular and is disposed around the connecting portion 22 .

[0097] By providing the fixing portion 21 in a ring shape, the connection area between the fixing portion 21 and the spoiler 1 is increased, thereby increasing the connection reliability between the fixing portion 21 and the spoiler 1 and further increasing the reliability of the rear wing spoiler assembly 10 .

[0098] Optionally, the spoiler 1 is provided with a positioning column 121, wherein the positioning column 121 is provided on a side of the second plate body 12 facing away from the first plate body 11. The positioning column 121 is used for positioning and cooperating with the rear door.

[0099] For example, the tailgate body 20 is provided with a positioning groove, and the positioning post 121 is inserted into the positioning groove and is positioned and matched with the positioning groove.

[0100] Therefore, when installing the rear wing spoiler assembly 10, the positioning column 121 can be first inserted into the positioning groove of the tailgate body 20 to achieve the positioning between the rear wing spoiler assembly 10 and the tailgate body 20, and then the fastener 3 is used to connect the rear wing spoiler assembly 10 to the tailgate body 20, thereby facilitating the installation and fixation of the rear wing spoiler assembly 10, which is beneficial to further improve the installation efficiency of the rear wing spoiler assembly 10.

[0101] The rear wing spoiler assembly 10 of the disclosed embodiment can be used for both low-end and high-end vehicles when the spoiler 1 is a plastic spoiler, which greatly improves the versatility of the spoiler 1 and at the same time well ensures the reliability and appearance requirements of the vehicle having the rear wing spoiler assembly 10.

[0102] like Figures 9 to 12As shown, the rear door of the embodiment of the present disclosure includes a rear door body 20 and a spoiler assembly 10, the rear door body 20 is provided with a fixing hole 201, or the rear door body 20 is provided with a spoiler movement mechanism, and the spoiler movement mechanism is provided with a fixing hole 201. The spoiler assembly 10 is the spoiler assembly 10 described in any of the above embodiments, and the fastener 3 is connected to the fixing hole 201.

[0103] For example, when the tailgate is a high-end model, the tailgate body 20 is provided with a tail wing movement mechanism, the tail wing movement mechanism is provided with a fixing hole 201, and the tail wing spoiler assembly 10 is connected to the tail wing movement mechanism through the fastener 3. When the tailgate is a low-end model, the tailgate body 20 is not provided with a tail wing movement mechanism, the fixing hole 201 is directly provided on the tailgate body 20, and the tail wing spoiler assembly 10 is connected to the tailgate body 20 through the fastener 3.

[0104] Since the spoiler 1 of the rear wing spoiler assembly of the embodiment of the present disclosure is universal, the rear door of the embodiment of the present disclosure has the advantages of low manufacturing cost and the like.

[0105] For high-end models, since the rear spoiler can be raised and lowered, an opening needs to be set on the rear door to accommodate the rear spoiler; while for low-end models, the rear spoiler does not rise and fall and is always higher than the rear door body, so there is no need to set an opening on the rear door. This results in the rear doors of high-end models and low-end models being unable to be manufactured using the same mold, resulting in higher vehicle manufacturing costs.

[0106] Alternatively, if Fig.10 As shown, the rear tailgate body 20 includes a tailgate body 202 and a shielding plate 203 .

The threaded column passes through the mounting hole and is connected with a nut to realize the connection between the shielding plate 203 and the back door body 202.

[0108] like Fig.10As shown, when the back door body 202 is used for a low-end vehicle, the shielding plate 203 is connected to the back door body 202, the shielding plate 203 is used to block the opening 2021 of the back door body 202, and the spoiler 1 is connected to the shielding plate 203 through the fastener 3. When the back door body 202 is used for a high-end vehicle, the shielding plate 203 is not used, that is, the opening 2021 remains open, the spoiler 1 is connected to the rear wing movement mechanism of the back door, and the spoiler 1 is stored in the opening 2021 when it is retracted. As a result, the back door body 202 can be used not only for low-end vehicles but also for high-end vehicles, so that the back door body 202 of the low-end vehicle and the back door body 202 of the high-end vehicle can be manufactured using the same set of molds, thereby reducing the manufacturing cost of the vehicle.

[0109] When manufacturing the back door body 202, the same set of molds is used for both high-end and low-end models. In addition, for the low-end model, another set of molds is designed to manufacture the shielding plate 203. The vehicle of the disclosed embodiment includes the back door described in any of the above embodiments. The vehicle can be a pure electric vehicle or a hybrid electric vehicle.

[0110] The tailgate of the embodiment of the present disclosure has the advantages of low manufacturing cost, and therefore, the vehicle of the embodiment of the present disclosure has the advantages of low manufacturing cost, and so on.

[0111] Although the embodiments of the present disclosure have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present disclosure. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present disclosure.
