Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to a vehicle. Background Technology

[0002] In a vehicle, the tailgate is a key opening and closing component at the rear. Its design directly affects the convenience of loading and unloading items for users, and also has a significant impact on the overall user experience.

[0003] In related technologies, there are two common structures for vehicle tailgates: one is a top-and-bottom tailgate, which consists of an upper tailgate and a lower tailgate. If the vehicle needs to install a spare tire, an external spare tire bracket is required; the other is a side-opening tailgate, where the spare tire can be directly installed on the door.

[0004] However, among the two types of tailgate structures mentioned above, the combination of a top-and-bottom tailgate with a spare tire bracket adds an extra step to opening the tailgate, making the operation process complicated; while the side-opening tailgate cannot provide the convenient loading and unloading functions of a top-and-bottom tailgate, making it difficult for the vehicle to meet the diverse usage needs of users. Utility Model Content

[0005] This application provides a vehicle that, on the one hand, allows the spare tire to be directly installed on the middle tailgate of the tailgate assembly, and on the other hand, enables the tailgate assembly to meet the usage scenarios of a top-and-bottom tailgate.

[0006] This application provides a vehicle including a body, a tailgate assembly, and a spare tire; the body has a rearward opening; the tailgate assembly is mounted on the opening, the tailgate assembly includes an upper tailgate, a middle tailgate, and a lower tailgate, the middle tailgate is located between the upper tailgate and the lower tailgate, the upper tailgate is rotatably connected to the top of the opening, the middle tailgate is rotatably connected to the side of the opening, and the lower tailgate is rotatably connected to the bottom of the opening; the spare tire is mounted on the outside of the middle tailgate.

[0007] Firstly, in the vehicle provided in this application, the spare tire is directly installed on the outside of the middle tailgate, eliminating the need for an external spare tire bracket. This simplifies the overall structure and avoids the extra opening steps required when using a bracket with the top and bottom doors, thus improving the convenience of retrieving the spare tire and opening and closing the tailgate components.

[0008] Secondly, the tailgate assembly includes an upper tailgate that can be rotatably connected to the top of the opening and a lower tailgate that can be rotatably connected to the bottom of the opening. This allows the upper and lower tailgates to work together to achieve the opening and closing function of a top and bottom door, meeting the user's need for convenient loading and unloading of items in normal scenarios. At the same time, the design of the middle tailgate rotatably connected to the side of the opening retains a flexible opening method similar to a side-opening tailgate, allowing users to choose the appropriate opening and closing form according to actual loading needs, effectively taking into account the adaptability of different usage scenarios.

[0009] As an optional implementation, when the tailgate assembly is in the closed state, the upper and lower ends of the middle tailgate overlap the outer sides of the upper tailgate and the lower tailgate, respectively.

[0010] This design creates a unified structure in the closed state, where the tailgate assembly forms a cohesive whole that supports each other and shares the load, rather than being a simple assembly of three independent parts. This disperses the force exerted on the tailgate assembly when subjected to external pressure (such as minor impacts or pressure), preventing deformation or damage to individual tailgate components due to concentrated stress, and effectively enhancing the overall structural strength and lifespan of the tailgate assembly.

[0011] As an optional implementation, the vehicle provided in this application further includes a first seal and a second seal; the middle tailgate includes a first tailgate body, a first overlap portion and a second overlap portion, the first overlap portion is connected to the top end of the first tailgate body, the second overlap portion is connected to the bottom end of the first tailgate body, and the first seal is installed on the upper tailgate or the first overlap portion; the lower tailgate includes a second tailgate body and a first extension portion, the first extension portion is connected to the second tailgate body, and the second seal is installed on the second overlap portion or the first extension portion; wherein, when the tailgate assembly is in the closed state, the first seal is sandwiched between the upper tailgate and the first overlap portion, and the second seal is sandwiched between the second overlap portion and the first extension portion.

[0012] This allows for a tighter filling of the gaps between the upper and middle tailgates, and between the middle and lower tailgates. This not only effectively prevents rainwater, dust, and other impurities from entering the vehicle's interior, but also further reduces the transmission path of external noise. Especially at high speeds, it reduces the intensity of wind noise entering the vehicle through the tailgate gaps, thus improving the overall sealing and quietness of the vehicle.

[0013] As an optional implementation, when the tailgate assembly is in the closed state, the first overlap portion bends and extends toward the side closer to the upper tailgate; both the first seal and the second seal include a connecting body and a compression portion; in the first seal, the connecting body is connected to the upper tailgate, the first overlap portion abuts against the compression portion, and the shape of the first overlap portion is adapted to the shape of the compression portion; in the second seal, the connecting body is connected to the second overlap portion, and the first extension portion abuts against the compression portion.

[0014] The shape of the first overlapping part is adapted to the shape of the compression part. This "shape matching + directional pressure" method allows the compression part to be deformed evenly under force, avoiding sealing dead corners caused by insufficient contact area or uneven force, so as to more fully fill the gap between the first overlapping part and the upper tail door. In the second seal, the compression part can independently undertake the sealing function, while the connecting body ensures the stable connection between the second seal and the second overlapping part. With dual protection, the sealing reliability between the upper tail door and the middle tail door, and between the middle tail door and the lower tail door can be effectively improved, further preventing rainwater, dust intrusion and noise transmission.

[0015] As an optional implementation, the vehicle provided in this application also includes a sealing ring disposed at the opening; wherein, when the tailgate assembly is in the closed state, the upper tailgate, middle tailgate and lower tailgate all press against the sealing ring.

[0016] In this way, it can largely prevent external rainwater, dust, strong winds and other elements from entering through the connection between the tailgate assembly and the vehicle body. Especially in heavy rain or muddy road conditions, it can effectively prevent rainwater from seeping into the vehicle body along the edge of the opening. At the same time, it can further reduce the wind noise generated by the friction between the external airflow and the vehicle body opening when driving at high speed, thus significantly improving the sealing, quietness and protection of the entire vehicle.

[0017] As an optional implementation, the vehicle provided in this application further includes a first hinge and an electric strut; the upper tailgate is rotatably connected to the vehicle body via the first hinge; one end of the electric strut is connected to the vehicle body, and the other end of the electric strut is connected to the upper tailgate, and the electric strut is used to drive the upper tailgate to open or close.

[0018] The first hinge, as the core connecting component, can precisely limit the rotation trajectory of the upper tailgate, preventing it from deviating or wobbling during opening or closing, ensuring that the upper tailgate always moves smoothly along the preset path. Especially when opened to the maximum angle, the first hinge can also provide stable support for the upper tailgate, preventing it from falling unexpectedly due to gravity, thus improving the structural stability and safety of the upper tailgate during opening and closing.

[0019] As an optional implementation, the vehicle provided in this application further includes a second hinge and a push rod motor; the second hinge includes a first leaf and a second leaf that are rotatably connected, the first leaf being connected to the vehicle body and the second leaf being connected to the tailgate; the push rod motor is mounted on the second leaf, the push rod motor has a push rod, the end of which is connected to the vehicle body, and the push rod motor is used to drive the tailgate to open or close.

[0020] In this way, it can be ensured that the tailgate always moves smoothly along the preset arc during side opening or closing; at the same time, the structure of the first plate being fixed to the vehicle body and the second plate being connected to the tailgate can evenly distribute the weight of the tailgate to the two second pivots, reducing the stress on a single pivot. This not only reduces the probability of wear after long-term use, but also provides stable support when the tailgate is opened to any angle, preventing accidental rotation due to gravity imbalance, and improving the structural stability and safety of the tailgate opening and closing process.

[0021] As an optional implementation, the vehicle provided in this application also includes a connecting frame, a driver, and a fixing seat; the connecting frame is fixed on the lower tailgate, the driver is disposed on the connecting frame, the fixing seat is mounted on the vehicle body, and the drive shaft of the driver passes through the connecting frame and is connected to the fixing seat; wherein, the driver is used to drive the lower tailgate to open or close.

[0022] In this way, the drive unit and the lower tailgate can be integrated into a single component, avoiding positional interference with other structures when the drive unit is installed separately. At the same time, the connecting bracket can be designed to fit the contour and space of the second tailgate body, ensuring the stability of the drive unit after installation and reducing the space occupied inside the lower tailgate. This allows for more storage or structural layout space in the lower tailgate, improving space utilization and the overall structural compactness.

[0023] As an optional implementation, the vehicle provided in this application also includes a limiting strut, one end of which is connected to a connecting frame and the other end of which is connected to the vehicle body when the tailgate is in the open state.

[0024] Among them, the limit strut can directly bear the weight load of the lower tailgate, avoiding fatigue damage to the drive shaft caused by the drive unit being subjected to force alone for a long time, or the lower tailgate falling unexpectedly due to loss of power support in extreme cases such as sudden power failure or drive unit failure; especially when the lower tailgate is open and carrying items (such as temporarily placing luggage, or users leaning against it to operate, etc.), the rigid support of the limit strut can further distribute the load, ensuring that the lower tailgate always maintains the preset opening angle and will not shake or shift, thus improving the structural stability and safety of the lower tailgate when it is open.

[0025] As an optional implementation, the vehicle provided in this application also includes a rear bumper, which is connected to the rear side of the vehicle body; wherein, when the tailgate is in the open state, the rear end of the tailgate is located behind the rear bumper.

[0026] This allows users to sit comfortably on the lower tailgate after it is opened. Attached Figure Description

[0029] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0030] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] In related technologies, there are two common structures for vehicle tailgates: one is a split tailgate, consisting of an upper tailgate and a lower tailgate, which requires an external spare tire carrier if a spare tire needs to be installed; the other is a side-opening tailgate, where the spare tire can be directly mounted on the tailgate. However, the split tailgate with a spare tire carrier adds an extra step to opening the tailgate, making the operation complicated; the side-opening tailgate, on the other hand, cannot provide the convenient loading and unloading capabilities of a split tailgate, making it difficult for the vehicle to meet the diverse needs of users.

[0032] Based on this, this application provides a vehicle with a three-section tailgate structure, which on the one hand allows the spare tire to be directly installed on the middle tailgate of the tailgate assembly, and on the other hand enables the tailgate assembly to meet the usage scenarios of a top and bottom tailgate.

[0033] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0034] Please combine Figures 1 to 2 , Figure 1 This is a three-dimensional structural diagram of a partial structure of the vehicle provided in an embodiment of this application. Figure 2 This is a three-dimensional structural diagram of the tailgate assembly in the open state of a vehicle provided in an embodiment of this application. As shown in the figure, an embodiment of this application provides a vehicle including a body 1, a tailgate assembly 2, and a spare tire 3. The body 1 has a rearward opening 11; the tailgate assembly 2 is installed in the opening 11, and the tailgate assembly 2 includes an upper tailgate 21, a middle tailgate 22, and a lower tailgate 23. The middle tailgate 22 is located between the upper tailgate 21 and the lower tailgate 23. The upper tailgate 21 is rotatably connected to the top of the opening 11, the middle tailgate 22 is rotatably connected to the side of the opening 11, and the lower tailgate 23 is rotatably connected to the bottom of the opening 11; the spare tire 3 is installed on the outside of the middle tailgate 22.

[0035] In the vehicle provided in this application, the spare tire 3 is directly installed on the outside of the middle tailgate 22, without the need for an external spare tire bracket. This simplifies the overall structure and avoids the extra opening steps required when the top and bottom doors are equipped with a bracket, thus improving the convenience of retrieving the spare tire 3 and opening and closing the tailgate assembly 2.

[0036] Secondly, the tailgate assembly 2 includes an upper tailgate 21 that can be rotatably connected to the top of the opening 11 and a lower tailgate 23 that can be rotatably connected to the bottom of the opening 11. This allows the upper tailgate 21 and the lower tailgate 23 to work together to achieve the opening and closing function of the top and bottom doors, meeting the user's need for convenient loading and unloading of items in normal scenarios. At the same time, the design of the middle tailgate 22 being rotatably connected to the side of the opening 11 retains a flexible opening method similar to a side-opening tailgate, allowing users to choose the appropriate opening and closing form according to actual loading needs, effectively taking into account the adaptability of different usage scenarios.

[0037] Please continue to combine Figure 3 , Figure 3 This is a schematic diagram illustrating the connection and cooperation between tailgate assemblies in a vehicle according to an embodiment of this application. It is understood that the tailgate assembly 2 has an open state and a closed state. In this embodiment, when the tailgate assembly 2 is in the closed state, the upper and lower ends of the middle tailgate 22 overlap the outer sides of the upper tailgate 21 and the lower tailgate 23, respectively. Thus, the tailgate assembly 2 forms a mutually supporting and cooperatively stressed integral structure in the closed state, rather than a simple splicing of three independent components.

[0038] In this way, the force exerted on the tailgate assembly 2 when subjected to external pressure (such as slight impact or pressing) can be dispersed, avoiding deformation or damage to a single tailgate component due to concentrated force, and effectively enhancing the overall structural strength and service life of the tailgate assembly 2.

[0039] Therefore, when the rear door assembly 2 provided in this embodiment needs to be opened, the middle rear door 22 should be opened first, and then the upper rear door 21 and the lower rear door 23 should be opened. It should be noted that the opening order of the upper rear door 21 and the lower rear door 23 is not important.

[0040] In specific usage scenarios, only the middle rear door 22 can be opened, allowing access to smaller items; alternatively, the middle rear door 22 can be opened first, followed by the lower rear door 23, allowing the user to sit on the lower rear door 23 to meet their outdoor activity needs, such as camping. The opening method of the rear door component 2 in other usage scenarios is not limited here.

[0041] Please continue to combine Figure 4 and Figure 5 , Figure 4 for Figure 3 A magnified view of the local structure at point A. Figure 5 for Figure 3 A magnified view of the partial structure at point B. To improve the overall sealing of the vehicle when the tailgate assembly 2 is closed, the vehicle provided in this embodiment also includes a first seal 4 and a second seal 5; the middle tailgate 22 includes a first tailgate body 221, a first overlap portion 222 and a second overlap portion 223, the first overlap portion 222 is connected to the top of the first tailgate body 221, the second overlap portion 223 is connected to the bottom of the first tailgate body 221, and the first seal 4 is installed on the upper tailgate 21 or the first overlap portion 222; the lower tailgate 23 includes a second tailgate body 231 and a first extension portion 232, the first extension portion 232 is connected to the second tailgate body 231, and the second seal 5 is installed on the second overlap portion 223 or the first extension portion 232; wherein, when the tailgate assembly 2 is closed, the first seal 4 is sandwiched between the upper tailgate 21 and the first overlap portion 222, and the second seal 5 is sandwiched between the second overlap portion 223 and the first extension portion 232.

[0042] When the tailgate assembly 2 is in the closed state, the first seal 4 is sandwiched between the upper tailgate 21 and the first overlap portion 222, and the second seal 5 is sandwiched between the second overlap portion 223 and the first extension portion 232. In this way, the gaps between the upper tailgate 21 and the middle tailgate 22, and between the middle tailgate 22 and the lower tailgate 23 can be filled more tightly. This not only effectively prevents rainwater, dust and other impurities from entering the vehicle body, but also further weakens the transmission path of external noise. Especially when driving at high speed, it can reduce the intensity of wind noise entering the vehicle through the tailgate gap and improve the overall sealing and quietness of the vehicle.

[0043] Secondly, the cooperation between the upper tailgate 21, the first overlapping portion 222 and the first seal 4, and the pressing cooperation between the second overlapping portion 223, the first extension portion 232 and the second seal 5, can compensate for the dimensional deviations that may exist in the processing or assembly of each tailgate component through the elastic deformation of the first seal 4 and the second seal 5. This avoids the problem of loose closure caused by the loose fit between components. At the same time, the elastic support of the first seal 4 and the second seal 5 can also provide a stable pre-tightening force for each tailgate component, so that the tailgate assembly 2 forms a more stable overall structure in the closed state, reducing the relative displacement of each tailgate component caused by vibration during vehicle operation, thereby reducing the probability of abnormal noise and extending the service life of the tailgate assembly 2.

[0044] Moreover, this fitting structure allows users to feel a smoother "fit feedback" when closing the tailgate assembly 2. The appropriate resistance of the first seal 4 and the second seal 5 ensures that each tailgate component is in place accurately, avoiding the "half-closed" phenomenon caused by poor fit.

[0045] In a specific implementation of this embodiment, in order for the lower tailgate 23 to fit snugly against the side of the vehicle body when the tailgate assembly 2 is in the closed state, the lower tailgate 23 further includes a second extension 233. The first extension 232 and the second extension 233 are respectively connected to opposite ends of the second tailgate body 231, and the second extension 233 abuts against the bottom of the side of the vehicle body.

[0046] To improve the sealing performance of the vehicle when the tailgate assembly 2 is closed, in some embodiments, when the tailgate assembly 2 is closed, the first overlap portion 222 bends and extends toward the side closer to the upper tailgate 21; both the first seal 4 and the second seal 5 include a connecting body 6 and a compression portion 7; in the first seal 4, the connecting body 6 is connected to the upper tailgate 21, the first overlap portion 222 abuts against the compression portion 7, and the shape of the first overlap portion 222 is adapted to the shape of the compression portion 7; in the second seal 5, the connecting body 6 is connected to the second overlap portion 223, and the first extension portion 232 abuts against the compression portion 7.

[0047] The shape of the first overlapping part 222 is adapted to the shape of the compression part 7. This "shape matching + directional pressure" method allows the compression part 7 to be deformed evenly under force, avoiding sealing dead corners caused by insufficient contact area or uneven force, so as to more fully fill the gap between the first overlapping part 222 and the upper tail door 21. In the second sealing member 5, the compression part 7 can independently undertake the sealing function, while the connecting body 6 ensures the stable connection between the second sealing member 5 and the second overlapping part 223. With dual protection, the sealing reliability between the upper tail door 21 and the middle tail door 22, and between the middle tail door 22 and the lower tail door 23 can be effectively improved, further blocking rainwater, dust intrusion and noise transmission.

[0048] In addition, the bending extension of the first overlapping part 222 can not only improve the fit with the first sealing element 4, but its bending shape can also form a certain elastic buffer during the pressing process. Combined with the deformation characteristics of the compression part 7, it can better compensate for the slight positional deviation that may occur between the upper tail door 21 and the middle tail door 22 during assembly or use, and avoid the fit jamming caused by rigid contact.

[0049] Meanwhile, the connecting bodies 6 of the first sealing element 4 and the second sealing element 5 are stably connected to the upper tail door 21 and the second overlapping part 223 respectively, which can ensure that the compression part 7 is always in the preset pressure position and will not shift due to the frequent operation of opening and closing the tail door, thus ensuring the long-term stability of the sealing effect.

[0050] Furthermore, the curved extension design of the first overlapping portion 222 can, to some extent, prevent its edge from scraping against the first seal 4. The compression portion 7, as an independent load-bearing component, can absorb the pressure through its own deformation, reducing direct wear between the first overlapping portion 222, the first extension portion 232, the first seal 4, and the second seal 5. The connecting body 6, not directly bearing the compressive stress, can maintain a stable connection with its corresponding components for a long time. In this way, the structural integrity of the first overlapping portion 222, the first extension portion 232, the first seal 4, and the second seal 5 can be protected, and the service life of each component can be extended, further improving the practical reliability of the back door assembly 2.

[0051] like Figure 4 and Figure 5 As shown, in a specific embodiment of this example, the side of the upper back door 21 connected to the connecting body 6 is a plane, and the side of the second overlapping part 223 connected to the connecting body 6 is a plane. Therefore, the side of the connecting body 6 away from the compression part 7 is a plane.

[0052] To further increase the elastic deformation of the first seal 4 and the second seal 5, thereby improving the fit between the first overlap 222 and the first seal 4, and between the first extension 232 and the second seal 5, a sealing lip 8 is also connected to the connecting body 6, and a cavity 71 is provided inside the compression part 7. This increases the elastic deformation of the first seal 4 and the second seal 5, thus improving their sealing performance.

[0053] Of course, the seal between the tailgate assembly 2 and the vehicle body also has a significant impact on the overall sealing performance of the vehicle. Therefore, please continue to consider... Figure 6 , Figure 6 for Figure 3A magnified view of the partial structure at point C. The vehicle provided in this embodiment also includes a sealing ring 9, which is disposed at the opening 11; wherein, when the tailgate assembly 2 is in the closed state, the upper tailgate 21, the middle tailgate 22 and the lower tailgate 23 all press against the sealing ring 9.

[0054] When the tailgate assembly 2 is closed, the edges of the upper tailgate 21, middle tailgate 22, and lower tailgate 23 all press against the sealing ring 9, which is equivalent to forming a complete outer sealing barrier at the junction of the tailgate assembly 2 and the body opening 11. In this way, it can block rainwater, dust, strong wind and other external elements from entering from the junction of the tailgate assembly 2 and the body 1 to a large extent. Especially in heavy rain or muddy road conditions, it can effectively prevent rainwater from seeping into the body 1 along the edge of the opening 11. At the same time, it can further reduce the wind noise generated by the friction between the external airflow and the body opening 11 when driving at high speed, so that the sealing quietness and protection of the whole vehicle are qualitatively improved.

[0055] Moreover, the sealing ring 9 can also accurately position the closed position of the tailgate assembly 2. Since the upper tailgate 21, middle tailgate 22, and lower tailgate 23 need to press against the sealing ring 9 simultaneously to achieve effective sealing, it requires that the upper tailgate 21, middle tailgate 22, and lower tailgate 23 accurately align with the contour of the opening 11 during the closing process. This indirectly ensures the overlap and fit accuracy between the upper tailgate 21 and the middle tailgate 22, and between the middle tailgate 22 and the lower tailgate 23, and avoids the failure of the internal sealing structure due to the deviation of the closing position of a single tailgate component.

[0056] In addition, the elastic deformation characteristics of the sealing ring 9 can provide a uniform preload force for the tailgate assembly 2, so that the upper tailgate 21, middle tailgate 22 and lower tailgate 23 are tightly fitted with the body opening 11 when closed, reducing the vibration gap between the tailgate assembly 2 and the body during vehicle operation, further reducing the possibility of abnormal noise and improving the overall structural stability.

[0057] Furthermore, the presence of the sealing ring 9 allows users to feel a more obvious "sealing feedback" when closing the tailgate assembly 2. Through the moderate resistance of the sealing ring 9, users can intuitively judge whether the tailgate assembly 2 is closed properly, thus avoiding sealing failure due to incomplete closure to a certain extent.

[0058] like Figure 6 As shown, in this embodiment, the sealing ring 9 includes a main body 91 and a sealing part 92. The main body 91 is connected to the vehicle body, and the sealing part 92 is connected to the main body 91. When the tailgate assembly 2 is in the closed state, the edges of the upper tailgate 21, the middle tailgate 22 and the lower tailgate 23 all press against the sealing part 92.

[0059] Of course, to increase the elastic deformation of the sealing ring 9, a compression chamber 921 can also be provided in the sealing part 92. By providing the compression chamber 921, the elastic deformation of the sealing ring 9 can be increased, thereby improving the sealing performance of the sealing ring 9. As for the shape of the main body 91, as long as it can balance the connection with the vehicle body and a large elastic deformation, the purpose of this embodiment can be achieved. Here, the shape of the main body 91 is not specifically limited.

[0060] The opening and closing of the upper tailgate 21, middle tailgate 22, and lower tailgate 23 are all electric, which will be described in detail below.

[0061] Please continue to combine Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of a partial structure of the tailgate assembly in the vehicle provided in the embodiment of this application, in the open state. Figure 8 This is a schematic diagram of the first partial structure of the tailgate assembly in the closed state in the vehicle provided in this application embodiment. In order to realize the opening and closing of the upper tailgate 21, the vehicle provided in this embodiment also includes a first hinge 10 and an electric strut 20; the upper tailgate 21 is rotatably connected to the vehicle body 1 through the first hinge 10; one end of the electric strut 20 is connected to the vehicle body 1, and the other end of the electric strut 20 is connected to the upper tailgate 21, and the electric strut 20 is used to drive the upper tailgate 21 to open or close.

[0062] Among them, the first hinge 10, as the core connecting component, can precisely limit the rotation trajectory of the upper tailgate 21, avoiding problems such as deviation and shaking during opening or closing, ensuring that the upper tailgate 21 always moves smoothly along the preset path. Especially when opened to the maximum angle, the first hinge 10 can also provide stable support for the upper tailgate 21, preventing the upper tailgate 21 from falling unexpectedly due to gravity, thus improving the structural stability and safety of the upper tailgate 21 during opening and closing.

[0063] Moreover, the electric drive of the electric strut 20 eliminates the need for users to manually lift or press the tailgate 21. They can control the electric strut 20 to open and close the tailgate 21 automatically by using in-vehicle buttons or remote control commands, which effectively lowers the barrier to entry and improves ease of operation.

[0064] Meanwhile, the electric strut 20 can also achieve functions such as opening and closing speed adjustment and precise stroke control through the built-in control module. For example, it can accelerate slowly during the opening process to avoid the impact caused by the rapid opening of the upper tail door 21.

[0065] Understandably, in order to improve the stability of the upper tailgate 21 during the opening and closing process, the aforementioned first hinge 10 and electric strut 20 can both be symmetrically set into two sets along the width direction of the vehicle body, thereby ensuring the stability of the upper tailgate 21 during the opening and closing process.

[0066] like Figure 7 As shown in the specific implementation of this embodiment, the first hinge 10 includes a first hinge leaf 101 and a second hinge leaf 102, which are rotatably connected by a first pivot 103. The opposite sides of the first hinge leaf 101 are connected to the vehicle body by first screws 30, and the second hinge leaf 102 is connected to the upper tailgate 21 by two second screws 40. To enhance the strength of the connection between the second hinge leaf 102 and the upper tailgate 21, a reinforcing plate 200 is also connected between the upper tailgate 21 and the second hinge leaf 102. This improves the structural strength of the second hinge leaf 102 and the effective connection between the upper tailgate 21 and the vehicle body 1.

[0067] It should be noted that the width direction of the aforementioned vehicle body 1 is... Figure 1 and Figure 2 The YY axis direction is always the same.

[0068] Please continue to combine Figure 9 , Figure 9 This is a schematic diagram of the second partial structure of the tailgate assembly in the closed state in the vehicle provided in this application embodiment. To achieve a rotatable connection between the tailgate 22 and the vehicle body 1, the vehicle provided in this embodiment further includes a second hinge 80 and a push rod motor 90. The second hinge 80 includes a first leaf 81 and a second leaf 82 rotatably connected. Specifically, the upper end of the first leaf 81 and the upper end of the second leaf 82, as well as the bottom end of the first leaf 81 and the bottom end of the second leaf 82, are rotatably connected via a second pivot 83. The first leaf 81 is connected to the vehicle body 1, and the second leaf 82 is connected to the tailgate 22. The push rod motor 90 is mounted on the second leaf 82 and has a push rod 901. The end of the push rod 901 is connected to the vehicle body 1, and the push rod motor 90 is used to drive the tailgate 22 to open or close.

[0069] The upper ends of the first leaf piece 81 and the second leaf piece 82, as well as the lower ends of the first leaf piece 81 and the second leaf piece 82, are rotatably connected via the second pivot 83. This ensures that the tailgate 22 moves smoothly along a preset arc during side opening or closing. Simultaneously, the structure where the first leaf piece 81 is fixed to the vehicle body 1 and the second leaf piece 82 is connected to the tailgate 22 evenly distributes the weight of the tailgate 22 onto the two second pivots 83, reducing the load on a single pivot. This not only lowers the probability of wear after long-term use but also provides stable support when the tailgate 22 is opened to any angle, preventing accidental rotation due to gravity imbalance and improving the structural stability and safety of the tailgate 22 during opening and closing.

[0070] Moreover, when the push rod motor 90 is working, the extension and retraction of the push rod 901 can drive the middle tail door 22 to rotate around the second pivot 83 through the second leaf 82, realizing automatic opening or closing without the need for manual pushing and pulling by the user. Especially in scenarios where the overall weight of the middle tail door 22 increases after the spare tire 3 is installed, it can eliminate the inconvenience of manual driving to a certain extent. Furthermore, the extension and retraction stroke of the push rod 901 of the push rod motor 90 can be precisely adjusted by the control system. For example, when closing, it can drive the middle tail door 22 to precisely press against the sealing ring 9 and the first sealing element 4, ensuring complete fit with the overlapping sealing structure of the upper tail door 21 and the lower tail door 23, avoiding sealing failure due to incomplete closure. At the same time, by adjusting the extension and retraction speed of the push rod 901, the impact of the middle tail door 22 when opening and closing can be reduced, improving the operational quality.

[0071] Please continue to combine Figure 10 , Figure 10 This is a schematic diagram of the third partial structure of the tailgate assembly in a vehicle in the closed state, as provided in an embodiment of this application. Figure 2 As shown, since the tailgate 22 in this embodiment is a side-opening type, a rotating connection structure should also be provided on the side where the tailgate 22 is rotatably connected to the vehicle body 1, for example, Figure 10 The transition hinge 220 is included. Specifically, the transition hinge 220 includes a first connecting page 230 and a second connecting page 240. The first connecting page 230 is connected to the vehicle body 1, and the second connecting page 240 is connected to the first tailgate body 221. The first connecting page 230 and the second connecting page 240 are rotatably connected by a connecting shaft.

[0072] The first connecting page 230 can be connected to the vehicle body 1 using screws or other threaded fasteners, and the second connecting page 240 can also be connected to the first tailgate body 221 using screws or other threaded fasteners. No specific restrictions are placed on the structure of the adapter hinge 220. Please continue to combine Figure 11 and Figure 12 , Figure 11This is a schematic diagram of the fourth partial structure of the tailgate assembly in the vehicle in the closed state, as provided in the embodiments of this application. Figure 12 This is a schematic diagram of the fifth partial structure of the tailgate assembly in the vehicle provided in the embodiment of this application when it is in the closed state. Of course, when the tailgate 22 is in the closed state, it also needs to be locked together with the vehicle body 1. Therefore, in the specific implementation of this embodiment, a first lock body 100 is provided on the first tailgate body 221 of the tailgate 22, and a first latch 210 can be provided at the position of the vehicle body 1 corresponding to the first lock body 100. The locking between the tailgate 22 and the vehicle body 1 is achieved by locking the first lock body 100 and the first latch 210.

[0073] The first latch 210 is fixed to a fixing plate 250, which can be connected to the vehicle body 1 by screws or other threaded fasteners. It should be noted that the first lock body 100 and the first latch 210 mentioned above both adopt conventional lock body and latch structures. Here, the specific structure of the first lock body 100 and the first latch 210 is not limited.

[0074] Please continue to combine Figure 13 and Figure 14 , Figure 13 This is a schematic diagram of the sixth partial structure of the tailgate assembly in the vehicle in the closed state, as provided in the embodiments of this application. Figure 14 for Figure 13 The diagram shows a partial structural schematic of the structure shown. To enable the opening and closing of the lower tailgate 23, the vehicle provided in this embodiment also includes a connecting frame 110, a driver 120, and a fixing seat 170; the connecting frame 110 is fixed on the second tailgate body 231 of the lower tailgate 23, the driver 120 is disposed on the connecting frame 110, and the fixing seat 170 is installed on the vehicle body 1, with the end of the fixing seat 170 away from the vehicle body 1 passing through the connecting frame 110 and drivingly connected to the driver 120; wherein, the driver 120 is used to drive the lower tailgate 23 to open or close.

[0075] In this way, the drive unit 120 and the lower tailgate 23 can be integrated into a single component, avoiding positional interference between the drive unit 120 and other structures when installed separately. At the same time, the connecting bracket 110 can be adapted to the contour and space of the second tailgate body 231, which can not only ensure the stability of the drive unit 120 after installation, but also reduce the occupation of the internal space of the lower tailgate 23, leaving more storage or structural layout space for the lower tailgate 23, thus improving space utilization and the compactness of the overall structure.

[0076] In a specific embodiment of this example, the connecting frame 110 includes a first extension plate 111 and a second extension plate 112 connected vertically. The second tailgate body 231 includes a main body plate 2311 and an inner plate 2312 connected to the inner side of the main body plate 2311. The first extension plate 111, the inner plate 2312 and the driver 120 are connected together, and the driver 120 is located above the inner plate 2312. The first extension plate 111 is located below the inner plate 2312. The end of the fixing seat 170 away from the vehicle body 1 passes through the second extension plate 112 and is driven to connect with the driver 120. The driving end of the driver 120 passes through the inner plate 2312 and is driven to connect with the fixing seat 170.

[0077] Please continue to combine Figure 15 , Figure 15 This is a schematic diagram of the seventh partial structure of the tailgate assembly in the closed state in the vehicle provided in this application embodiment. In order to restrict the position of the lower tailgate 23 when it is in the open state, in some optional embodiments, the vehicle provided in this embodiment also includes a limiting strut 130. When the lower tailgate 23 is in the open state, one end of the limiting strut 130 is connected to the second extension plate 112, and the other end of the limiting strut 130 is connected to the vehicle body 1.

[0078] Among them, the limiting strut 130 can directly bear the weight load of the lower tailgate 23, avoiding fatigue damage to the drive shaft 121 caused by the long-term independent force on the drive 120, or the lower tailgate 23 falling unexpectedly due to loss of power support in extreme cases such as sudden power failure or drive 120 failure; especially when the lower tailgate 23 is open and carrying items (such as temporarily placing luggage, user leaning on it for operation, etc.), the rigid support of the limiting strut 130 can further distribute the load, ensuring that the lower tailgate 23 always maintains the preset opening angle and will not shake or shift, thus improving the structural stability and safety of the lower tailgate 23 in the open state.

[0079] In addition, users can open the lower tailgate 23 to a suitable angle according to the size requirements of the items to be loaded or unloaded, and then maintain this state with the support of the limiting strut 130. There is no need to continuously operate the drive 120 or manually hold the lower tailgate 23. Especially when loading or unloading large or irregular items (such as furniture, outdoor equipment, etc.), it can free up the user's hands to focus on moving the items, significantly improving operational efficiency. At the same time, when the lower tailgate 23 is closed, the limiting strut 130 can be naturally retracted with the rotation of the second extension plate 112, avoiding taking up extra space and not interfering with the vehicle body 1 or other tailgate components (such as the upper tailgate 21 and the middle tailgate 2), ensuring the smooth operation of the three-section tailgate assembly 2.

[0080] It should be noted that, in order to improve the stability of the lower tailgate 23 during the opening and closing process, the aforementioned connecting frame 110 and limiting support rod 130 can each be symmetrically set in two along the width direction of the vehicle body 1.

[0081] Please continue to combine Figure 16 , Figure 16 This is a schematic diagram of the eighth partial structure of the tailgate assembly in the vehicle in the closed state according to an embodiment of this application. It is understood that when the tailgate 23 is in the closed state, it is necessary to lock the tailgate 23 and the vehicle body 1 together. Therefore, in the specific implementation of this embodiment, a second lock body 140 and a second latch 150 are also included. The second lock body 140 is connected to the vehicle body, and the second latch 150 is connected to the main body plate 2311 of the tailgate 23 via a second connecting plate 160. Specifically, the second latch 150 is inserted into the second connecting plate 160, and the second connecting plate 160 is connected to the main body plate 2311 via two fourth screws 190.

[0082] It is understandable that, in order to improve the stability of the lower tailgate 23 in the closed state, the aforementioned second latch 150 and second lock body 140 can also be symmetrically set as two in the width direction of the vehicle body 1.

[0083] Furthermore, to improve the usability of the lower tailgate 23 in the vehicle provided in this embodiment after it is opened, the vehicle provided in this embodiment also includes a rear bumper (not shown in the figure), which is connected to the rear side of the vehicle body 1; wherein, when the lower tailgate 23 is in the open state, the rear end of the lower tailgate 23 is located behind the rear bumper. In this way, after the lower tailgate 23 is opened, it is convenient for the user to sit on the lower tailgate 23.

[0084] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
