AI Technical Summary
Due to space constraints in structures such as door locks and hinges, existing side-opening tailgates cannot integrate taillights into the vehicle body, which increases the complexity of the body-in-white structure. Furthermore, forcibly arranging taillights would reduce the strength of the tailgate and its off-road performance.
In the design of integrating taillights on the side-opening tailgate, the positions of the sealing strip and door lock are adjusted to be staggered in the width direction to provide space for taillight installation. The height of the hinge assembly is also increased to avoid the taillight position. At the same time, the reinforcement structure of the tailgate inner panel is enhanced, including reinforcement members and cavity structures to improve strength and stability.
The taillights were effectively integrated, the body-in-white structure was simplified, the strength and off-road performance of the tailgate were improved, the vibration and deformation of the tailgate were reduced, and the off-road riding comfort was improved.

Abstract
Description
Technical Field
[0001] This application belongs to the field of side-opening tailgate technology, and particularly relates to a side-opening tailgate and vehicle with integrated taillights. Background Technology
[0002] Vehicles with spare tire suspension typically mount the spare tire on the tailgate (also known as the tailgate, rear tailgate, or luggage compartment door). Because the tailgate is heavy due to the spare tire, it opens to the left or right, hence the name "side-opening tailgate".
[0003] The side-opening tailgates on the market usually have the tailgate lock and limiting structure on the left, the spare tire suspended in the middle, and the hinge on the right. Due to the space constraints of the location of the door lock, hinge and other structures, the taillight structure of the traditional top and bottom opening tailgate cannot be implemented on the side-opening tailgate. All taillight functions must be placed on the body, which increases the complexity of the body-in-white structure. Summary of the Invention

Detailed Implementation
[0059] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0060] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0061] Please see Figure 1 and Figure 2 The diagram shows the front and rear views of a side-opening tailgate 100 in the related art. One side of the side-opening tailgate 100 is equipped with a door lock 130 and a limiting structure 190, while the other side is equipped with an upper hinge 141 and a lower hinge 142. In the related art, the side-opening tailgate 100 typically prioritizes the installation requirements of a spare tire 160, and the arrangement of all door locks 130 and hinges revolves around the placement space of the spare tire 160. Figure 3 The diagram shows a cross-sectional view of the lock 130 of a side-opening rear door 100 in the related art. The sealing strip 120 and the lock 130 are arranged side-by-side along the thickness direction of the rear door and completely overlap along the width direction of the rear door. Figure 2 and Figure 3 It can be seen that the door lock 130, the limiting structure 190, and the handle 180 completely occupy the left side space, leaving no space for the taillight. The right hinge occupies a higher position. In order to place the spare tire 160 in the best position, a right-off arrangement is adopted, which places the spare tire 160 on the right side closer to the hinge. There is no space for the taillight on the right side of the spare tire 160.
[0062] As an important exterior and functional component, the taillights must be arranged symmetrically on both sides and not be obstructed by the spare tire 160. Based on the above analysis, due to space constraints, taillights cannot be installed on the side-opening tailgate 100; therefore, all taillight functions must be placed entirely on the vehicle body, specifically on both sides of the luggage compartment opening at the rear of the vehicle. The need to install the taillights increases the complexity of the body-in-white structure.
[0063] Furthermore, the side-opening tailgate 100 primarily meets off-road requirements, while the suspended spare tire 160 is an important functional requirement. If the taillights are forcibly placed on the side-opening tailgate 100, the strength of the tailgate will be greatly reduced, resulting in insufficient tailgate performance during off-road driving (such as tailgate vibration, abnormal noise, and deformation).
[0064] Therefore, this application provides a side-opening tailgate 100 and a vehicle, aiming to at least partially solve the problems existing in current side-opening tailgates. The side-opening tailgate 100 provided by this application can not only be equipped with conventional taillights, but also improve the strength and performance of the tailgate, reduce tailgate vibration under extreme off-road conditions, and improve off-road performance. The content of this application will be described in detail below with reference to the accompanying drawings and embodiments.
[0065] For ease of description, the various directions involved in the embodiments are defined as follows: In the field of vehicle technology, the length direction of a vehicle is generally referred to as the X-direction or longitudinal direction, the width direction as the Y-direction or lateral direction, and the height direction as the Z-direction or vertical direction. The side-opening tailgate is installed at the rear end of the vehicle; the width direction of the side-opening tailgate is also the width direction of the vehicle, i.e., the Y-direction; the height direction of the side-opening tailgate is also the height direction of the vehicle, i.e., the Z-direction; and the thickness direction of the side-opening tailgate is also the length direction of the vehicle, i.e., the X-direction. The interpretations of the relevant directional descriptions in the following embodiments can refer to the above content.
[0066] Please see Figure 4 , Figure 5 and Figure 8 According to a first aspect of this application, a side-opening tailgate 100 is provided, including a door body 110 and a sealing strip 120, a door lock 130, a hinge assembly 140, a first taillight 151, and a second taillight 152 mounted on the door body 110. The door body 110 is the main body of the side-opening tailgate 100, used to cover the opening of the vehicle's luggage compartment, and also serves as the mounting base for various accessories on the side-opening tailgate 100. The sealing strip 120, the door lock 130, and the hinge assembly 140 are conventional accessories on the side-opening tailgate 100. The sealing strip 120 is disposed on the inner side of the door body 110 to seal the door body 110 against the vehicle body. Door lock 130 is used to lock with the lock seat of the vehicle body. Door lock 130 is located on the first side of the inner side of door body 110. Hinge assembly 140 is used to hinge door body 110 to vehicle body. Hinge assembly 140 is located on the second side of the inner side of door body 110, and is located outside the area enclosed by sealing strip 120. For ease of understanding, the first side is defined as the left side of side-opening tailgate 100 and the second side is defined as the right side of side-opening tailgate 100. In the following text, the first side is equivalent to the left side (abbreviated as L) and the second side is equivalent to the right side (abbreviated as R). Of course, in other embodiments, the right side of side-opening tailgate 100 is also regarded as the first side and the left side of side-opening tailgate 100 as the second side.
[0067] Please see Figure 5 and Figure 6 Unlike conventional side-opening back doors 100 where the sealing strip 120 is mounted on the door lock 130, in this application, the door lock 130 is located within the area enclosed by the sealing strip 120. That is, the door lock 130 and the sealing strip 120 are staggered in the width direction of the door body 110. By changing the arrangement of the door lock 130 and the sealing strip 120 from being arranged side-by-side in the X direction to being arranged side-by-side in the Y direction, the space occupied by the door lock 130 and the sealing strip 120 in the thickness direction of the door body 110 can be reduced. This allows space to be created for the first taillight 151 in the thickness direction of the door body 110. The first taillight 151 is located on the first side of the outer surface of the door body 110. The first taillight 151 and the door lock 130 are arranged side-by-side in the thickness direction of the door body 110 without overlapping, and the first taillight 151 and the door lock 130 do not interfere with each other.
[0068] Please see Figure 7 In some embodiments, to further optimize the arrangement of the first taillight 151, the sealing strip 120, and the door lock 130, along the thickness direction of the door body 110, the sealing strip 120 overlaps with the door lock 130, and the sealing strip 120 does not extend beyond the location of the door lock 130. That is, the sealing strip 120 is completely located within the extension space of the door lock 130 in the X direction, and the sealing strip 120 does not occupy the thickness space of the door body 110. Along the width direction of the door body 110, the sealing strip 120 and the door lock 130 are arranged side by side, and both overlap with the first taillight 151 at least partially. This is equivalent to the sealing strip 120 and the door lock 130 being located in front of the first taillight 151. The first taillight 151 does not occupy additional space in the Y direction and does not affect the arrangement of the spare tire 160.
[0069] By arranging the sealing strip 120 and the door lock 130 side by side in the Y direction, with the door lock 130 located within the area enclosed by the sealing strip 120, not only is installation space provided for the first taillight 151, but the size of the trunk opening is also not affected (e.g., Figure 24 As shown, the opening size L of the suitcase is the size of the middle of the sealing strip 120. The opening size of the suitcase should be as large as possible to facilitate the placement of luggage. For the same size side-opening tailgate 100, this application not only solves the problem of the placement of the first taillight 151 by arranging the door lock 130 in the area surrounded by the sealing strip 120, but also increases the opening size of the suitcase. Furthermore, the door lock 130 is arranged in the dry area (the area surrounded by the sealing strip 120), which improves the sealing and water-resistant performance of the side-opening tailgate 100.
[0070] Please see Figure 5In some embodiments, the side-opening tailgate 100 is further provided with a limiting structure 190, and the vehicle body is provided with a limiting groove that cooperates with the limiting structure 190. The limiting structure 190 is located below the door lock 130, and the limiting structure 190 and the door lock 130 are located within the area enclosed by the sealing strip 120. After the door lock 130 is locked, the limiting block of the limiting structure 190 extends into the limiting groove and engages in place, which serves to prevent the tailgate from sinking in the Z direction and to prevent the tailgate from rotating backward in the X direction.
[0071] Please see Figure 8 , Figure 9 and Figure 10 In this application, the height of the uppermost hinge of the hinge assembly 140 is higher than that of a conventional side-opening tailgate 100, exceeding the height of the second taillight 152. This causes the second taillight 152 and the uppermost hinge of the hinge assembly 140 to be offset in the Z-direction, resolving the space issue for taillight arrangement on the hinge side. The height of the second taillight 152 is the same as that of the first taillight 151, satisfying aesthetic requirements.
[0072] It should be noted that the second taillight 152 and the uppermost hinge in the hinge assembly 140 are offset in the Z-direction. This means that the second taillight 152 and the uppermost hinge in the hinge assembly 140 do not completely overlap in the Z-direction. In other words, the overall height of the uppermost hinge in the hinge assembly 140 is higher than that of the second taillight 152. Specifically, this can be achieved by the upper side of the uppermost hinge in the hinge assembly 140 being higher than the upper side of the second taillight 152, and the lower side being higher than the lower side of the second taillight 152, meaning that the second taillight 152 and the uppermost hinge in the hinge assembly 140 are side-by-side and partially overlap in the Z-direction. Alternatively, the lower side of the uppermost hinge in the hinge assembly 140 may be higher than the upper side of the second taillight 152, meaning that the second taillight 152 and the uppermost hinge in the hinge assembly 140 are side-by-side and do not overlap in the Z-direction.
[0073] During the design phase, the position of the taillights is first determined based on the desired aesthetic effect. Based on the taillights' position, the position of the uppermost hinge in the weatherstripping 120, door lock 130, and hinge assembly 140 is then determined. To stably support the door body 110, the hinge assembly 140 typically includes at least two hinges. Figure 8 The specific structure and distribution of the hinge assembly 140 in some embodiments are shown. (Combined with...) Figure 8 The hinge assembly 140 includes an upper hinge 141 and a lower hinge 142 spaced apart along the height direction of the door body 110. The height of the second taillight 152 is less than that of the upper hinge 141 and greater than that of the lower hinge 142. In other embodiments, if the overall height of the side-opening tail door 100 is large, the hinge assembly 140 may include three or four hinges.
[0074] Please see Figure 11 , Figure 12 and Figure 13 The diagram illustrates the structural schematics of the door body 110 and its components in certain embodiments. The door body 110 includes a connected outer rear door panel assembly 111 and an inner rear door panel assembly 112. A first taillight 151 and a second taillight 152 are both mounted on the outer rear door panel assembly 111. A sealing strip 120, a door lock 130, and a hinge assembly 140 are all mounted on the inner rear door panel assembly 112. The outer rear door panel assembly 111 and the inner rear door panel assembly 112 are connected using at least one of the following methods: threaded fasteners 162, riveting, welding, bonding, and FDS (Firmware Distributed Sealing). The specific connection method is not limited in this application.
[0075] In some embodiments, please refer to Figure 13 and Figure 14 The rear door inner panel assembly 112 includes a rear door inner panel 1121 and a central reinforcing unit 1123, a door lock reinforcing member 1122, and a hinge reinforcing member 1124 connected to the rear door inner panel 1121. The door lock reinforcing member 1122, the central reinforcing unit 1123, and the hinge reinforcing member 1124 are distributed sequentially along the width direction of the door body 110. The door lock reinforcing member 1122 is connected to the left side of the rear door inner panel 1121 and at least covers the area where the door lock 130 is located. The hinge reinforcing member 1124 is connected to the right side of the rear door inner panel 1121 and at least covers the area where the hinge is located. The central reinforcing unit 1123 is connected to the middle area of the rear door inner panel 1121 and at least covers the connection area of the fastener for fixing the spare tire 160.
[0076] The central reinforcement unit 1123, door lock reinforcement 1122, and hinge reinforcement 1124 all enclose the inner panel 1121 of the tailgate to form a cavity 112a structure. The cavity 112a structure minimizes the vibration transmitted from the spare tire 160 to the tailgate, improves the tailgate strength and vibration mode, solves the problem of tailgate vibration and deformation under extreme off-road conditions and poor road surfaces (rough roads) after the spare tire 160 is installed, and improves off-road riding comfort.
[0077] Please see Figure 14In some embodiments, the inner panel 1121 of the rear door is provided with a window frame 11211 for installing the rear windshield. The upper ends of the door lock reinforcement 1122 and the hinge reinforcement 1124 extend to the upper edge of the window frame 11211. The middle parts of the door lock reinforcement 1122 and the hinge reinforcement 1124 are connected to the middle reinforcement unit 1123 to completely cover the lower edge and both sides of the window frame 1121. The door lock reinforcement 1122, the middle reinforcement unit 1123, and the hinge reinforcement 1124 together with the inner panel 1121 of the rear door form a closed cavity 112a structure, thereby dispersing the vibration of the spare tire 160 from the middle reinforcement unit 1123 to various areas of the side-opening rear door 100. During the transmission process, the vibration is weakened by the energy absorption of the cavity 112a structure, avoiding excessive vibration impact from being transmitted to weak points.
[0078] In related technologies, the side-opening tailgate 100 does not require a taillight. Therefore, the height of the uppermost hinge in the hinge assembly 140 is lower than the lower edge of the window frame 11211. In embodiments where the hinge assembly 140 includes an upper hinge 141 and a lower hinge 142, the height of the upper hinge 141 is lower than the lower edge of the window frame 11211. Since the window frame 11211 has less material around its perimeter and is relatively weak, placing the upper hinge 141 below the lower edge of the window frame 11211 avoids this weak area and improves the structural strength of the hinge mounting point. However, in this application, since a second taillight 152 needs to be installed, and given that the position of the second taillight 152 is already determined (based on the aesthetic effect), the height of the uppermost hinge in the hinge assembly 140 is increased so that its height is flush with the lower edge of the window frame 11211. For this purpose, please refer to [link to relevant documentation]. Figure 10 , Figure 13 and Figure 21 The hinge reinforcement 1124 and the inner panel 1121 of the back door form a cavity 112a structure at the hinge mounting point and above, which increases the size of the upper cavity 112a structure formed by the inner panel 1121 of the back door and the hinge reinforcement 1124 at the lower edge of the window frame 11211. This is more conducive to improving the structural performance of the window frame 11211 of the side-opening back door 100, improving the structural strength of the weak point of the back door, and improving the various performances of the back door.
[0079] In some embodiments, any one of the door lock reinforcement 1122, the central reinforcement unit 1123, and the hinge reinforcement 1124 can be configured as a single-piece structure, for example, formed in one piece by casting or stamping, and its material can be high-strength steel, cast aluminum, magnesium-aluminum alloy, or other alloy materials. In other embodiments, any one of the door lock reinforcement 1122, the central reinforcement unit 1123, and the hinge reinforcement 1124 can also be configured as a single piece composed of multiple components connected together by welding, threaded fasteners 162, riveting, FDS, etc., and the multiple components can be made of the same or different materials, and their thicknesses can be the same or different. The structure, material, and thickness of the door lock reinforcement 1122, the central reinforcement unit 1123, and the hinge reinforcement 1124 in this application are not limited, as long as they can meet the strength requirements of the side-opening back door 100.
[0080] In some embodiments, the door lock reinforcement 1122, the central reinforcement unit 1123, and the hinge reinforcement 1124 are all constructed from parts connected by different materials and / or thicknesses. Specifically, the main load-bearing structures (components connecting the spare tire 160, door lock 130, hinge, handle 180, or other accessories) in the door lock reinforcement 1122, central reinforcement unit 1123, and hinge reinforcement 1124 are made of high-strength materials and have a greater thickness, while other components that only support the rear door outer panel assembly 111, wiring harness, sensors (such as radar, reversing camera, etc.) are made of ordinary materials and / or have a reduced thickness. The different components are welded together, and the segmented welded closed structure obtained by using components of different thicknesses and materials ensures structural strength while reducing structural weight and cost.
[0081] Figure 15 , Figure 17 and Figure 19 The specific structures of the door lock reinforcement 1122, the central reinforcement unit 1123, and the hinge reinforcement 1124 in certain embodiments are shown respectively. Please refer to... Figure 15 and Figure 16The door lock reinforcement 1122 includes a first upper corner reinforcement plate 11221, a door lock reinforcement plate 11222, and a lower corner reinforcement plate 11223 connected sequentially along the height direction. The first upper corner reinforcement plate 11221 is used to reinforce the upper left corner area of the window frame 11211, and its shape is adapted to the shape of the upper left corner of the window frame 11211. The lower corner reinforcement plate 11223 is used to reinforce the lower left corner area of the back door inner panel 1121, and its shape is adapted to the shape of the lower left corner of the back door inner panel 1121. The first upper corner reinforcement plate 11221 and the lower corner reinforcement plate 11223 can be made of steel plate or aluminum plate, with a thickness not exceeding 1 mm and a yield strength of 200~350 MPa. The door lock reinforcement plate 11222 is the main load-bearing structure of the door lock reinforcement 1122, and the door lock 130 is connected to both the back door inner panel 1121 and the door lock reinforcement plate 11222. The door lock reinforcement plate 11222 is made of high-strength steel and other high-strength materials, with a yield strength of over 460MPa and a thickness of over 1.5mm.
[0082] Please see Figure 17 and Figure 18 The central reinforcing unit 1123 includes an upper reinforcing beam 11231, a lower reinforcing beam 11232, a left reinforcing beam 11233, a right reinforcing beam 11234, and a window frame reinforcing plate 11235. The upper reinforcing beam 11231, the lower reinforcing beam 11232, the left reinforcing beam 11233, and the right reinforcing beam 11234 are connected to form a frame structure 11236. This frame structure 11236 can be quadrilateral or grid-shaped. Figure 18 In the central reinforcing unit 1123 of the illustrated embodiment, the left reinforcing beam 11233 and the right reinforcing beam 11234 have the same structure and dimensions, and mainly support the spare tire 160. The left and right ends of the upper reinforcing beam 11231 extend outwards from the connection points between the upper reinforcing beam 11231 and the left and right reinforcing beams 11233 and 11234, respectively, and connect to the door lock reinforcing plate 11222 and the hinge reinforcing plate 11242. The right end of the lower reinforcing beam 11232 extends to the right from the connection point between the lower reinforcing beam 11232 and the right reinforcing beam 11234, and connects to the hinge reinforcing plate 11242. All four components of this frame structure 11236 are made of high-strength materials such as high-strength steel, with a yield strength of over 460 MPa and a thickness of over 1.5 mm. The window frame reinforcing plate 11235 is connected to the upper reinforcing beam 11231. The window frame reinforcing plate 11235 is used to reinforce the lower edge of the window frame 11211. Its length is less than that of the upper reinforcing beam 11231. The window frame reinforcing plate 11235, together with the first upper corner reinforcing plate 11221 and the lower corner reinforcing plate 11223, can be made of steel plate or aluminum plate. Its thickness does not exceed 1mm and its yield strength is 200~350MPa.
[0083] Considering the high structural strength of frame structure 11236, its connection with the tailgate inner panel 1121 can significantly strengthen the corresponding area of the tailgate inner panel 1121. Therefore, please refer to... Figure 14 In some embodiments, a weight-reducing hole 1121a is provided in the center of the inner panel 1121 of the tailgate. A frame structure 11236 is located on the outer periphery of the weight-reducing hole 1121a and is connected to the area of the inner panel 1121 located around the weight-reducing hole 1121a. The frame structure 11236 has at least four spare tire mounting holes 1123a for installing spare tire 160 mounting bolts. The spare tire mounting holes 1123a are located in at least one set of relatively reinforcing beams of the frame structure 11236, and the spare tire mounting holes 1123a abut against the outer panel assembly 111 of the tailgate. Accordingly, please refer to... Figure 12 The outer panel assembly 111 of the rear door also needs to be provided with mounting holes 1111b for bolts to pass through. In some embodiments, there are 6 spare tire mounting holes 1123a and 6 mounting holes 1111b, with the 6 spare tire mounting holes 1123a symmetrically distributed on the left reinforcing beam 11233 and the right reinforcing beam 11234.
[0084] In some embodiments, the first taillight 151 of the side-opening tailgate 100 overlaps with the door lock 130 in the X direction, and the second taillight 152 overlaps with the upper hinge 141. In this case, the spare tire 160 must be positioned symmetrically in the middle of the side-opening tailgate 100 to avoid obstructing the taillights and affecting lighting requirements. Therefore, the spare tire mounting hole 1123a also needs to be positioned in the middle of the side-opening tailgate 100.
[0085] Please see Figure 19 and Figure 20The hinge reinforcement 1124 includes a second upper corner reinforcement plate 11241, a hinge reinforcement plate 11242, and at least one nut plate 11243 connected together. The first upper corner reinforcement plate 11221 is used to reinforce the upper right corner area of the window frame 11211, and its shape is adaptively adjusted according to the shape of the upper right corner of the window frame 11211. The second upper corner reinforcement plate 11241 can be made of steel or aluminum plate, with a thickness not exceeding 1 mm and a yield strength of 200~350 MPa. The hinge reinforcement plate 11242 at least covers all mounting points of the hinge assembly 140, and the hinge reinforcement plate 11242 is provided with a plurality of hinge mounting holes 1124a, and each nut plate 11243 is respectively connected to the hinge mounting holes 1124a of the hinge reinforcement plate 11242. The hinge reinforcement plate 11242 is the main load-bearing structure of the hinge reinforcement 1124. The hinge is connected to the inner panel 1121 of the rear door, the hinge reinforcement plate 11242, and the nut plate 11243. The hinge reinforcement plate 11242 is made of high-strength materials such as high-strength steel, with a yield strength of over 460MPa and a thickness of over 1.5mm. The nut plate 11243 is mainly used to provide threads for effective screwing with the hinge mounting bolts. Its load-bearing requirements are between those of the second upper corner reinforcement plate 11241 and the hinge reinforcement plate 11242, and its material strength and thickness are also between those of the second upper corner reinforcement plate 11241 and the hinge reinforcement plate 11242.
[0086] In one specific embodiment, the door lock reinforcing plate 11222, upper reinforcing beam 11231, lower reinforcing beam 11232, left reinforcing beam 11233, right reinforcing beam 11234, and hinge reinforcing plate 11242 are all made of high-strength steel with a yield strength of approximately 500 MPa and a thickness of 2 mm; the nut plate 11243 is made of medium-strength steel with a yield strength of approximately 350 MPa and a thickness of 1.5 mm; the first upper corner reinforcing plate 11221, lower corner reinforcing plate 11223, window frame reinforcing plate 11235, and second upper corner reinforcing plate 11241 are all made of high-strength steel with a yield strength of approximately 275 MPa and a thickness of 0.7 mm. All components are welded and fixed at their joints.
[0087] Please see Figure 21 In the embodiment where the hinge assembly 140 includes an upper hinge 141 and a lower hinge 142, both the upper reinforcing beam 11231 and the lower reinforcing beam 11232 are connected to the hinge mounting holes 1124a of the hinge reinforcing plate 11242. Specifically, the hinge reinforcing plate 11242 has two sets of hinge mounting holes 1124a, and the nut plate 11243 has two corresponding holes. The right end of the upper reinforcing beam 11231 is connected to the upper part of the hinge reinforcing plate 11242, and simultaneously supports the lower right corner of the window frame 11211 and the mounting location of the upper hinge 141; the right end of the lower reinforcing beam 11232 is connected to the lower part of the hinge reinforcing plate 11242, and simultaneously supports the lower right corner of the back door and the mounting location of the lower hinge 142.
[0088] The door lock reinforcement 1122, the central reinforcement unit 1123, and the hinge reinforcement 1124 are all located on the side of the inner rear door panel 1121 facing the outer rear door panel assembly 111, and simultaneously serve to support the outer rear door panel assembly 111. Please refer to... Figure 16 , Figure 18 and Figure 20 In some embodiments, one or more outer plate supports 1125 are provided on the door lock reinforcement 1122, the middle reinforcement unit 1123, and the hinge reinforcement 1124. The outer plate supports 1125 are welded and fixed to the parts connected to them on the door lock reinforcement 1122, the middle reinforcement unit 1123, and the hinge reinforcement 1124, and are bonded to the back door outer panel assembly 111 by shock-absorbing adhesive. For embodiments where the back door inner panel 1121 is provided with a weight-reducing hole 1121a, an outer plate support 1125 can be installed at the weight-reducing hole 1121a. The function of the outer plate support 1125 is only to support the back door outer panel assembly 111 to prevent deformation and to improve the modal characteristics of the back door outer panel assembly 111. Therefore, the strength and / or thickness of the outer plate support 1125 is less than that of the nut plate 11243. The outer plate support 1125 can be made of steel plate or aluminum plate, with a thickness not exceeding 1 mm and a yield strength of 200~350 MPa.
[0089] Please combine Figure 22 The closed cavity 112a structure in the inner panel assembly 112 of the tailgate transmits vibrations as follows: During driving on rough roads, the spare tire 160 causes the tailgate to vibrate vertically and horizontally. The vibration of the spare tire 160 is dispersed and transmitted by the central reinforcing unit 1123, where the upper reinforcing beam 11231 connects the upper right hinge mounting structure of the hinge reinforcing plate 11242 to the window frame 11211. Figure 21 As shown, this design effectively enhances the installation performance of the upper hinge 141. The installation location of the upper hinge 141 employs a closed annular cavity 112a structure. Vibration is absorbed within this cavity, preventing vibration deformation from being transmitted to weak points (the upper and side edges of the window frame 11211). The door lock reinforcement 1122 and hinge reinforcement 1124 reinforce the left and right edges of the window frame 11211, respectively. Together, these structures reduce the risk of deformation at the weak points of the rear door, improving road durability. Furthermore, the reinforced hinge installation structure enhances the anti-sinking performance of the side-opening rear door 100.
[0090] In some embodiments, in addition to the weight-reducing hole 1121a surrounded by the central reinforcing unit 1123, the inner panel 1121 of the tailgate may also be provided with other weight-reducing holes 1121a as needed, for example, another weight-reducing hole 1121a may be provided on the left side of the inner panel 1121. The reinforcing structure in the inner panel assembly 112 adopts a segmented welded closed structure, which can use different material thicknesses and materials. Together with the several weight-reducing holes 1121a on the inner panel 1121, the structural weight and cost of the inner panel assembly 112 are reduced.
[0091] Please see Figure 7 and Figure 24 In some embodiments, the first side of the inner tailgate panel 1121 has an extension edge 11212 that bends towards the outer tailgate panel assembly 111 and extends outward. The inner tailgate panel 1121 is a stamped sheet metal part with a groove shape to accommodate the central reinforcing unit 1123, the door lock reinforcing member 1122, and the hinge reinforcing member 1124. The extension edge 11212 is located at the groove opening and extends outward. A sealing strip 120 is installed on the extension edge 11212. The thickness of the sealing strip 120 does not exceed the groove depth, so that the sealing strip 120 does not occupy additional space in the thickness direction. The part of the door lock 130 that couples with the lock seat of the vehicle body is located on the groove wall and locks with the lock seat of the vehicle body in the X direction.
[0092] The tailgate outer panel assembly 111 includes a tailgate outer panel 1111 and two taillight mounting plates 1112 respectively installed on both sides of the tailgate outer panel 1111. The taillight mounting plates 1112 are welded and fixed to the tailgate outer panel 1111. The taillight mounting plates 1112 are connected to the tailgate inner panel 1121, the door lock reinforcement plate 11222, and the hinge reinforcement plate 11242 using structural adhesive. By designing the tailgate outer panel assembly 111 as a split structure, the larger tailgate outer panel 1111 can be a simple sheet metal structure with a simple manufacturing process. The relatively complex taillight mounting plates 1112 are smaller in size and are independently molded. The first taillight 151 and the second taillight 152 are respectively installed on the corresponding taillight mounting plates 1112. Since the projection of the first taillight 151 and the door lock 130 in the X direction overlaps, and the projection of the second taillight 152 and the upper hinge 141 in the X direction overlaps or is close in position, the door lock reinforcing plate 11222 that reinforces the mounting area of the door lock 130 and the hinge reinforcing plate 11242 that reinforces the mounting area of the upper hinge 141 can also strengthen the mounting structure of the first taillight 151 and the second taillight 152, thus solving the problem of insufficient tail door performance caused by the presence of taillights.
[0093] Please see Figure 23 and Figure 24 In some embodiments, the side-opening tailgate 100 also includes a spare tire 160, which is mounted on a spare tire bracket 161. The spare tire bracket 161 is connected to the door body 110 via a threaded fastener 162. Correspondingly, please refer to [link to relevant documentation]. Figure 22In some embodiments, the central reinforcing unit 1123 is provided with three spare tire support blocks 170. The spare tire support blocks 170 are made of elastic material, such as rubber, silicone, or springs. The tailgate outer panel assembly 111 is provided with three through holes 1111a for the spare tire support blocks 170 to extend outward through the through holes 1111a, forming a triangular support structure. When the spare tire 160 vibrates, the three elastic spare tire support blocks 170 first reduce and filter the vibration energy of the spare tire 160. The remaining vibration energy is transmitted to the closed cavity 112a structure of the tailgate inner panel assembly 112 through several mounting points of the spare tire bracket 161, thus fully reducing and absorbing the vibration energy. It is understood that for side-opening tailgates without a spare tire 160, the spare tire support blocks 170 may not be provided, and the corresponding through holes 1111a are not required on the tailgate outer panel assembly 111.
[0094] To improve the installation strength of the spare tire support block 170, please refer to [link / reference needed]. Figure 18 In some embodiments, the central reinforcing unit 1123 further includes a mounting bracket 11237, and three spare tire support blocks 170 are respectively installed at the connection points of the upper reinforcing beam 11231 and the left reinforcing beam 11233, the connection points of the upper reinforcing beam 11231 and the right reinforcing beam 11234, and the mounting bracket 11237. Furthermore, in some embodiments, the material strength and / or thickness of the mounting bracket 11237 are greater than that of the nut plate 11243, and the material and thickness of the mounting bracket 11237, the upper reinforcing beam 11231, the left reinforcing beam 11233, and the right reinforcing beam 11234 can be consistent, so that the structural strength at the installation points of the three spare tire support blocks 170 is the same.
[0095] The side-opening tailgate 100 of this application and Figure 1 Vibration tests were conducted on the side-opening tailgate 100 in the related technology shown. The verification tests demonstrated that the side-opening tailgate 100 of this application improved the vibration problem of the spare tire 160 by 77%, a significant effect. Specific test results are shown in the table below:
[0096]
[0097] In summary, the side-opening tailgate 100 provided in this application adopts a segmented welding structure for the taillight panel structure, and adds structural adhesive to connect it with the tailgate inner panel 1121, door lock reinforcing plate 11222, and hinge reinforcing plate 11242, completely solving the adverse effects on strength caused by the taillight breaking the tailgate panel structure. The right taillight mounting structure cooperates with the central reinforcing unit 1123 and hinge reinforcing member 1124, adopting a closed cavity reinforcing structure. The structure is connected left and right and top and bottom through welding, which particularly strengthens the structural performance near the upper hinge 141. Specifically, the cavity structure of the upper reinforcing beam 11231 supports the hinge mounting surface of the tailgate inner panel 1121, which increases the size of the cavity structure and greatly improves the structural performance. The reinforcing structure of the tailgate inner panel assembly 112 can be integrated using different material thicknesses, reducing the assembly weight and parts cost, greatly saving the working space and fixture costs of the welding process, improving production efficiency, and reducing the difficulty of production operations. The side-opening tailgate 100 provided in this application can not only meet the requirements for taillight assembly, but also install a spare tire 160. It has excellent anti-sinking performance and extreme off-road performance, and can meet the needs of both outdoor off-roading and urban outings.
[0098] According to a second aspect of this application, a vehicle is provided, including a vehicle body and a side-opening tailgate 100 as described in any of the first aspects above. The rear of the vehicle body is provided with a luggage compartment. The side-opening tailgate 100 is hinged to the vehicle body via a hinge assembly 140 and the opening of the luggage compartment is sealed by a sealing strip 120. The vehicle body is provided with a lock seat that engages with a door lock 130 of the side-opening tailgate 100.
[0099] In the embodiment where the side-opening tailgate 100 is provided with a limiting structure 190, the vehicle body is provided with a limiting groove that cooperates with the limiting structure 190. After the door lock 130 is locked, the limiting block of the limiting structure 190 extends into the limiting groove and is engaged, which plays the role of preventing the tailgate from sinking in the Z direction and preventing the tailgate from rotating backward in the X direction.
[0100] The vehicle can be an SUV, MPV, or off-road vehicle, with no specific model limitation. Other undescribed structures of the vehicle can be found in relevant existing art disclosures, and will not be elaborated here.
[0101] Because the vehicle is equipped with the aforementioned side-opening tailgate 100, it has the following beneficial effects:
[0102] (1) The taillights of this vehicle are fully arranged on the side-opening tailgate 100. The problem of taillight arrangement of the side-opening tailgate 100 is solved by staggered overlapping taillight arrangement structure. The left taillight is optimized by reducing the overlap between the sealing strip 120 and the door lock 130 in the front and rear directions, so that the taillight and the door lock 130 are set side by side, ensuring the taillight function. The adjustment of the sealing strip 120 position increases the opening size of the luggage compartment, making it easier to put luggage. The right taillight is optimized by increasing the upper plate cavity 112a, which also increases the structural performance. The increased cavity 112a structure at the lower right corner of the tailgate window frame 11211 not only meets the assembly requirements of the right taillight and the uppermost right hinge, but also strengthens the structural strength of the uppermost right hinge installation location, providing good anti-sinking performance and extreme off-road performance for the installation of the spare tire 160.
[0103] (2) The side-opening tailgate of the vehicle adopts a closed annular cavity 112a structure. During off-road and rough road driving, the spare tire 160 causes the tailgate to vibrate. The vibration of the spare tire 160 is dispersed and transmitted by the frame structure 11236. The upper reinforcing beam 11231 connects the upper hinge 141 mounting structure and the window frame 11211, which can better enhance the installation performance of the hinge. The cavity 112a structure absorbs vibration and reduces amplitude, avoiding vibration deformation from being transmitted to the weak point at the top of the window frame 11211, thus improving road durability. In addition, several reinforcing structures in the tailgate inner panel assembly 112 adopt a segmented welded closed structure, which can use different material thicknesses and materials, reducing structural weight and cost, greatly saving the working space and fixture costs of the welding process, improving production efficiency, and reducing the difficulty of production operations.
[0104] (3) For models with a spare tire 160, three rubber blocks are installed on the side-opening tailgate 100 to form a triangular stable support structure. The three rubber blocks can compressively contact the spare tire 160. The rubber blocks are installed on the closed cavity 112a structure. When the spare tire 160 vibrates, the triangularly distributed rubber blocks first reduce the amplitude of the spare tire 160 vibration and filter some of the vibration energy. The remaining vibration and energy are transmitted to the closed cavity 112a structure through the spare tire bracket 161 mounting point, which fully reduces and absorbs the vibration energy, enhances the extreme off-road performance of the off-road vehicle, and improves the passenger comfort.
