Detailed Implementation

[0025] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0026] Unless otherwise explicitly specified and limited, the terms "setup," "installation," and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms based on the specific circumstances.

[0027] The terms “upper,” “lower,” “left,” “right,” “front,” “back,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.

[0029] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0030] To facilitate understanding of the positional and connection relationships of the components in this utility model, refer to Figure 1 The coordinate system in the figure is based on the vehicle coordinate system, which is a special moving coordinate system used to describe the motion of a car. The origin of the vehicle coordinate system coincides with the center of mass of the vehicle. When the vehicle is stationary on a horizontal road, the X direction of the coordinate system refers to the direction parallel to the direction of the car's travel, that is, the front-to-back direction; the Y direction refers to the width direction of the car, that is, the left-to-right direction; and the Z direction refers to the height direction of the car, that is, the up-down direction.

[0031] like Figure 1 As shown, the vehicle rear wing assembly proposed in this utility model includes a main body 10, which is mounted on the tailgate 20 of the vehicle. The tailgate 20 is configured to open and close, and the main body 10 moves synchronously with the tailgate 20.

[0032] Combination Figure 1 and Figure 2 The main body 10 includes a first connector 11 and a second connector 12. The second connector 12 is connected to the first connector 11, and the first connector 11 is connected to the rear door 20. That is, the second connector 12 is installed to the rear door 20 through the first connector 11. The second connector 12 constitutes a decorative part of the appearance of the main body 10. Figure 3 and Figure 4 One of the first connector 11 and the second connector 12 has a positioning groove 112, and the other has a positioning wing 122 protruding. When the first connector 11 and the second connector 12 are connected, the positioning wing 122 is engaged in the positioning groove 112.

[0033] Reference Figure 1 The main body 10 has a large length dimension in the Y direction of the vehicle. Its Y-direction dimension roughly matches that of the tailgate 20. Due to the shape of the tailgate 20 and the overall design of the vehicle, it usually has a certain curvature. During assembly, it is easy to have insufficient precision, which brings certain difficulties to the assembly of the main body 10. This will cause gaps between the first connector 11 and the second connector 12, making it easy for water to enter. It is also easy to generate wind noise, affecting the vehicle's NVH (Noise, Vibration, and Harshness) performance.

[0034] This utility model, through the cooperation of positioning groove 112 and positioning wing 122, can realize the positioning connection of the first connector 11 and the second connector 12, which is beneficial to improve the assembly accuracy of the main body 10, avoid the problem of internal water or dust impurities caused by connection errors, and avoid the problem of gaps between the first connector 11 and the second connector 12 due to improper installation, which can easily generate wind noise during vehicle operation. In particular, for the tail wing whose Y-axis dimension matches the Y-axis dimension of the tailgate 20, it solves the problem of complex positioning and difficult assembly caused by its length and curvature. The structure is simple and improves assembly efficiency and quality.

[0035] Since the second connector 12 is installed to the tailgate 20 through the first connector 11, that is, one side of the first connector 11 is connected to the second connector 12, and the other side is connected to the tailgate 20, for ease of understanding, refer to... Figure 2 The side of the first connector 11 used to connect with the second connector 12 is defined as the first side, and the side of the first connector 11 used to connect with the tailgate 20 is defined as the second side. That is, the second connector 12 is installed on the first side of the first connector 11, and the second side of the first connector 11 is connected to the tailgate 20.

[0036] In one embodiment, such as Figure 3 As shown, a support member 111 protrudes from the rear end of the first side of the first connector 11, which is combined with... Figure 2 and Figure 4 The rear end of the second connector 12 is provided with a rear wing plate 121. The rear wing plate 121 protrudes and extends towards the side closer to the tailgate 20, that is, the rear wing plate 121 protrudes and extends towards the second side closer to the first connector 11. When the first connector 11 and the second connector 12 are connected, the rear end of the support member 111 contacts and connects with the front end of the rear wing plate 121. The rear wing plate 121 covers the outside of the support member 111. The rear wing plate 121 enables the second connector 12 to present an upturned wing shape in appearance. The support member 111 can support the rear wing plate 121 to ensure the structural stability of the rear wing plate 121.

[0037] In this example of Embodiment 1, refer to Figure 2 The angle between the rear wing 121 and the second connecting member 12 is an acute angle.

[0038] In this example of Embodiment 1, as Figure 3 As shown, the positioning groove 112 is formed on the support member 111 and extends through the support member 111 along the X direction of the vehicle, combined with Figure 2 and Figure 4 The positioning wing 122 protrudes from the front end of the rear wing plate 121. When the first connector 11 and the second connector 12 are connected, the positioning wing 122 is engaged in the positioning groove 112 so as to realize the positioning function of the support 111 and the rear wing plate 121 in the Y direction, and to make the support 111 and the rear wing plate 121 fit together in the X direction, thereby achieving positioning in the X direction. This ensures that the connection and positioning of the first connector 11 and the second connector 12 are accurate, and avoids water leakage and wind noise problems due to assembly errors.

[0039] In this example of Embodiment 1, as Figure 3 As shown, the first connector 11 has a boss 113 on its first side. The boss 113 and the support member 111 are spaced apart in the X direction. A guide rib 114 is provided between the support member 111 and the boss 113. One end of the guide rib 114 is connected to the front end of the support member 111 and the other end is connected to the boss 113. The guide rib 114 can increase the structural strength and stability of the support member 111, thereby ensuring the stable connection between the support member 111 and the rear wing plate 121.

[0040] For example, the support member 111, the boss 113, the guide rib 114 and the first connector 11 are integrally formed.

[0041] For example, such as Figure 3As shown, a water guide groove 115 is provided on the support member 111. The water guide groove 115 passes through the support member 111 and is located on one side of the guide rib 114. If water enters the second connector 12 and the first connector 11 (usually water enters in the X direction), it can be discharged in time through the water guide groove 115. In addition to its structural reinforcement function, the guide rib 114 can also guide water to the water guide groove 115 and discharge it through the water guide groove 115, so as to avoid the internal water accumulation affecting the connection quality between the main body 10 and the back door 20.

[0042] In this first embodiment, the first connector 11 and the second connector 12 are connected by adhesive, more specifically, in combination Figure 2 and Figure 3 The first connector 11 includes a connecting surface 11a, which is located on the first side of the first connector 11 and is spaced apart from the support member 111 in the X direction. The connecting surface 11a is provided with adhesive, and the connecting surface 11a is bonded to the second connector 12. The support member 111 and the rear wing plate 121 are provided with adhesive to achieve bonding, thereby realizing the connection between the first connector 11 and the second connector 12.

[0043] For example, such as Figure 2 As shown, the front end of the second connector 12 is provided with a stop 123. The stop 123 protrudes and extends towards the side closer to the back door 20, that is, it protrudes and extends towards the second side closer to the first connector 11, so as to cover the front end of the first connector 11 and prevent the first connector 11 from being exposed.

[0044] In one embodiment, such as Figure 5 As shown, the second side of the first connector 11 has a first positioning post 116 protruding, which, in conjunction with... Figure 6 The back door 20 is provided with a first positioning hole 21 that cooperates with the first positioning post 116. The diameter of the first positioning hole 21 in the Y direction is larger than the diameter of the first positioning post 116 in the Y direction. When the first positioning post 116 is accommodated in the first positioning hole 21, it has an adjustment amount in the Y direction. With this setting, the first connecting member 11 can be finely adjusted in the Y direction so that the positioning of the first connecting member 11 and the back door 20 is accurate.

[0045] In this example of Embodiment 1, the first positioning post 116 is located in the middle of the first connector 11 in the Y direction. This arrangement allows the middle of the first connector 11 to be positioned in the X direction and has an adjustment amount in the Y direction, so as to facilitate the adjustment and positioning of both sides of the first connector 11 in the Y direction.

[0046] In this example of Embodiment 1, as Figure 5 As shown, the second side of the first connector 11 has a second positioning post 117 protruding from it. The second positioning post 117 is located on both sides of the first positioning post 116 in the Y direction, and is combined with... Figure 6 The back door 20 is provided with a second positioning hole 22 that mates with the second positioning post 117. The diameter of the second positioning hole 22 in the X direction is larger than that of the second positioning post 117 in the X direction. When the second positioning post 117 is accommodated in the second positioning hole 22, it is positioned in the Y direction and has an adjustment range in the X direction. This setting allows for fine-tuning of the X-direction position of the first connector 11 on both sides in the Y direction to ensure accurate installation of the first connector 11 and the back door 20. This helps to avoid problems such as poor overall appearance and easy water leakage caused by installation errors of the main body 10.

[0047] In this first embodiment, the first positioning post 116, the second positioning post 117 and the first connecting member 11 are integrally formed.

[0048] In this first embodiment, the first positioning post 116 and / or the second positioning post 117 are positioning pins, and the first positioning hole 21 and / or the second positioning hole 22 are oblong holes, which are simple in structure and easy to process.

[0049] In one embodiment, combined with Figure 5 and Figure 6 One of the first connector 11 and the back door 20 is provided with a fastener 118, and the other is provided with a slot 23. The positions of the fastener 118 and the slot 23 are configured to be located on one side of the first positioning post 116 and / or the second positioning post 117. When the first connector 11 and the back door 20 are connected, the fastener 118 is engaged in the slot 23. After positioning is completed, the fastener 118 is engaged in the slot 23, which can realize the pre-installation of the first connector 11 and the back door 20 and avoid the first connector 11 from shifting its position relative to the back door 20 during the positioning process.

[0050] In this first embodiment, the fastener 118 protrudes from the second side of the first connector 11, and the slot 23 is formed on the back door 20.

[0051] For example, the fastener 118 is located on one side of the second positioning post 117. This arrangement allows the first connector 11 to be pre-fixed after its position relative to the back door 20 is adjusted by the cooperation of the second positioning post 117 and the second positioning hole 22. This prevents the first connector 11 from shifting during subsequent assembly and improves assembly efficiency.

[0052] For example, the fastener 118 adopts a snap-fit ​​structure.

[0053] In one embodiment, combined with Figure 2 and Figure 5 The second side of the first connector 11 has a protruding fixing post 119, and the fixing post 119 has a fixing hole 1191, which is used for connection. Figure 6The back door 20 has a through hole 24 for accommodating the fixing post 119. When the first connector 11 is connected to the back door 20, the fixing post 119 passes through the through hole 24 to achieve connection with the back door 20. The fixing post 119 is then fixed to the back door 20 through the fixing hole 1191.

[0054] In this example of Embodiment 1, as Figure 5 As shown, a connecting rib 1192 protrudes from the outer periphery of the fixed column 119. The connecting rib 1192 is connected to the first connecting member 11. The connecting rib 1192 is used to increase the structural strength of the fixed column 119 and the connection stability with the first connecting member 11.

[0055] For example, the fixing hole 1191 is used to install a self-tapping screw, and the setting of the connecting rib 1192 can reduce the probability of the fixing post 119 cracking when the self-tapping screw is driven into the fixing hole 1191, thereby helping to ensure the stability of the connection.

[0056] For example, the fixing column 119, the connecting rib 1192 and the first connecting member 11 are integrally formed.

[0057] In this example of Embodiment 1, the fixing posts 119 are distributed in the middle and at both ends of the first connector 11. This arrangement ensures the stability of the main body 10 during installation and effectively prevents the ends of the main body 10 from warping. The fixing posts 119 do not need to consider the thickness and internal space dimensions of the main body 10, thus ensuring connection quality and effectively preventing warping. Especially in some cases, to ensure the overall design harmony of the vehicle, the internal space of the main body 10 may not be sufficient to accommodate the installation structure. The fixing posts 119 are not limited by space and ensure connection quality.

[0058] In one embodiment, the aforementioned boss 113 forms a cavity at one end near the back door 20, that is, a cavity is formed on the second side of the first connector 11. The aforementioned first positioning post 116, second positioning post 117, fastener 118 or slot 23 and fixing post 119 are all disposed in the cavity and are integrally formed with the first connector 11.

[0059] Reference Figure 2 When the second connector 12 is installed on the tailgate 20 through the first connector 11, there is a gap between the lower end of the stop 123 and the rear wing 121 and the surface of the tailgate 20. This gap can ensure the assembly quality of the main body 10 and the tailgate 20, avoid squeezing or scratching the surface of the tailgate 20 during the assembly process, and facilitate the assembly. During assembly, it is only necessary to ensure a sealed connection between the first connector 11 and the tailgate 20.

[0060] In one embodiment, combined with Figure 2 and Figure 5A first sealing element 13 is provided between the first connector 11 and the tailgate 20. The first sealing element 13 is located at the X-direction edges of the second side of the first connector 11 to ensure that the first connector 11 is sealed to the tailgate 20 in the X direction, which helps to prevent water or dust and other impurities from entering between the first connector 11 and the tailgate 20.

[0061] For example, the first seal 13 is made of sealing foam.

[0062] In this example of Embodiment 1, as Figure 5 As shown, a second sealing member 14 is provided between the first connector 11 and the back door 20. The second sealing member 14 is located at the two edges of the Y direction on the second side of the first connector 11 to ensure that the two ends of the first connector 11 are sealed to the back door 20 in the Y direction. This helps to prevent water or dust and other impurities from entering between the first connector 11 and the back door 20, and can effectively prevent the two ends of the main body 10 from warping.

[0063] For example, the second seal 14 is made of sealing foam.

[0064] For example, such as Figure 5 As shown, a guide strip 141 protrudes from the second side of the first connector 11. The guide strip 141 is located at the X-direction and / or Y-direction edges of the second side of the first connector 11. A sealing strip is provided on one side of the guide strip 141. The sealing strip includes the aforementioned first sealing element 13 and / or second sealing element 14. The sealing strip contacts the guide strip 141. More specifically, the guide strip 141 is used to guide the first sealing element 13 and / or second sealing element 14. When the first sealing element 13 and / or second sealing element 14 are laid, they can be laid along the guide strip 141, which can ensure the laying efficiency of the sealing strip and prevent the guide strip 141 from shifting. Especially after long-term use, it can prevent the deformation and shrinkage of the sealing strip from causing positional displacement, thereby ensuring the sealing performance for a long time.

[0065] Furthermore, the guide strip 141 is located outside the sealing strip, meaning that the sealing strip is closer to the center of the first connector 11 than the guide strip 141. This arrangement ensures that the sealing strip does not fail.

[0066] The guide strip 141 can also provide structural support for the main body 10. After the main body 10 has been in use for a long time, problems such as collapse may occur. The guide strip 141 can contact the back door 20 (a certain gap can be reserved between the guide strip 141 and the back door 20 during installation to ensure installation quality). When the sealing strip deforms and shrinks after long-term use, the guide strip 141 can contact the back door 20 to ensure the overall structural stability of the main body 10.

[0067] Based on the above, this utility model also proposes a vehicle, including a tailgate 20 and the aforementioned vehicle rear wing assembly mounted thereon.

[0068] In one embodiment, such as Figure 7 As shown, the back door 20 includes an outer panel 201 and an inner panel 202, which are connected. The aforementioned second positioning hole 22, slot 23 and through hole 24 are all provided on the outer panel 201. The inner panel 202 is provided with a fastening hole 25, which is matched with the position of the fixing hole 1191 to fix the fixing post 119 to the back door 20.

[0069] An avoidance groove 26 is provided on the inner panel 202. The avoidance groove 26 is matched with the first positioning hole 21 and the second positioning hole 22 so as to adjust the position of the main body 10 relative to the back door 20 by means of the first positioning post 116 and the second positioning post 117. The avoidance groove 26 can also reduce weight, which is beneficial to improving the user experience of the back door 20.

[0070] Since the vehicle proposed in this utility model adopts all the technical solutions of all the above-described vehicle rear wing assembly embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0071] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
