Description

Technical Field

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

[0002] The tailgate is the rear door of a vehicle, primarily used for passenger entry and exit and for loading and unloading goods. For vehicles such as Sport Utility Vehicles (SUVs) or commercial vehicles, the tailgate is typically larger than that of a regular sedan, providing easy access to the vehicle's interior when open. A typical split tailgate design features both the upper and lower doors hinged between their closed and open positions; the upper door closes by rotating downwards and opens by rotating upwards, while the lower door closes by rotating upwards and opens by rotating downwards.

[0003] Due to the limitations of this split tailgate design, a spare tire cannot be mounted at the rear, which may cause some concern for users on long journeys and directly impact the user experience. This is especially true for off-road vehicles, where users have a strong need for an externally mounted spare tire to handle emergencies such as tire blowouts while traversing mountains and rivers. Utility Model Content

[0004] This application provides a split tailgate and vehicle, and through the structural optimization of the split tailgate, it provides a good technical guarantee for improving the user experience.

[0005] The first aspect of this application provides a split tailgate, which includes a first door and a second door, with the first door located above the second door. The first door is configured to rotate between a closed and an open position, with its rotating portion located on its side. The second door is configured to rotate between a closed and an open position, with its rotating portion located at its bottom. This configuration allows the first door to open laterally around its rotating portion, and the second door to open downwards around its rotating portion. Based on the side-rotating opening characteristic of the first door, it possesses a high load-bearing capacity. A spare tire can be externally mounted on the first door as needed, and the added weight of the spare tire does not affect the load-bearing capacity of the first door during side rotation. Overall, this effectively improves the user experience.

[0006] In addition, the first door opens at a slight angle to the side, allowing for easy access to luggage in the trunk, effectively preventing luggage from slipping out when parking on a slope and further enhancing the user experience. Furthermore, the split tailgate structure provided in this embodiment also helps enhance the safety of the escape mode; if the vehicle falls into water, quick escape can be achieved by opening only the first door.

[0007] Based on the first aspect, this application also provides a first implementation of the first aspect: the split tailgate further includes a spare tire, which is mounted on the first door. Due to the reliable installation of the spare tire, it can be applied to various scenarios such as camping or fishing, effectively improving the user experience. For SUVs or off-road vehicles, this technological advantage is even more significant.

[0008] Based on the first embodiment of the first aspect, this application also provides a second embodiment of the first aspect: the rotating part of the first door is located on the left side of the first door or on the right side of the first door. This allows for configuration according to different user needs, providing good adaptability.

[0009] Based on the first implementation method of the first aspect, or the second implementation method of the first aspect, this application also provides a third implementation method of the first aspect: the height of the first door is greater than the height of the second door. Based on the defined rear opening of the vehicle body, on the one hand, the first door side has a spare tire mounting space that avoids the rear window, meeting emergency needs while also ensuring the driver's rear visibility. On the other hand, the second door has a smaller turning radius when opened; when the second door is horizontally open, the user is relatively close to the trunk when retrieving or placing luggage, effectively reducing the effort required for luggage handling.

[0010] Based on the third embodiment of the first aspect, this application also provides a fourth embodiment of the first aspect: the spare tire is located at the lower part of the first door. This avoids obstructing the rear window, allowing the driver to obtain a good rear view through the rear window. Simultaneously, the available space in the height direction can be fully utilized to arrange the rotating part of the first door, resulting in better rotational performance and load-bearing capacity.

[0011] In practical applications, the first door may include a door body and a rear window glass, with a tailgate window frame provided on the upper part of the door body, and the rear window glass set in the tailgate window frame.

[0012] For example, the rear window glass may include two panes of glass, at least one of which is slidably disposed relative to the tailgate window frame to open the rear window glass as needed.

[0013] Based on the first aspect, or the first embodiment of the first aspect, or the second embodiment of the first aspect, this application also provides a fifth embodiment of the first aspect: the first door further includes a handle, which is located on the opposite side of the rotating part of the first door. Thus, the first door can be opened and closed by pulling the handle around its rotating part.

[0014] Based on the first aspect, or the first embodiment of the first aspect, this application also provides a sixth embodiment of the first aspect: the first vehicle door includes a left sub-door and a right sub-door that open side-by-side, the left sub-door being rotatable between a closed position and an open position, with the rotating part of the left sub-door located on its left side; the right sub-door being rotatable between a closed position and an open position, with the rotating part of the right sub-door located on its right side. Based on the two side-by-side sub-doors, the spare tire can be externally mounted on either the left or right sub-door.

[0015] For example, the left and right sub-doors can be arranged symmetrically or asymmetrically.

[0016] Based on the first aspect, or the first implementation of the first aspect, or the second implementation of the first aspect, this application also provides a seventh implementation of the first aspect: a hook is further provided on the first car door. This arrangement allows for the hanging of tools such as backpacks as needed, facilitating user access and operation.

[0017] A second aspect of this application provides a vehicle including a body and a tailgate located at the rear of the body, the tailgate being a split tailgate as described above.

[0018] For example, the vehicle can be a gasoline-powered vehicle, a hybrid vehicle, or an electric vehicle. Attached Figure Description

[0029] Body 20. Detailed Implementation

[0030] This application provides a solution for a split tailgate, which, through reasonable optimization of the split tailgate structure, enables the spare tire to be suspended at the rear of the vehicle, providing a good technical guarantee for improving user experience.

[0031] With the rapid development of the automotive industry, automobiles have become an indispensable part of people's lives, and people's demands for the convenience and practicality of cars are also increasing. Currently, the tailgate, as the rear door of a car, is mainly used for passenger entry and exit and loading and unloading of goods; its convenience is a crucial factor for most users. For SUVs or commercial vehicles, the tailgate is usually larger than that of ordinary sedans. A typical split tailgate design features both the upper and lower doors hinged between their closed and open positions. The upper door closes by rotating downwards and opens by rotating upwards, while the lower door closes by rotating upwards and opens by rotating downwards. When both doors are opened as a whole relative to the rear of the vehicle, they provide convenient access to the interior.

[0032] Due to the limitations of this split tailgate design, placing the spare tire on the upper door would result in excessive weight, restricting the corresponding drive, transmission, and support functions. Placing it on the lower door would require the spare tire to occupy the rear bottom area as the door opens and closes, limiting the lower door's opening angle to avoid collisions with the rear of the vehicle. Furthermore, the spare tire would extend rearward beyond the door when open, affecting passenger entry and exit, and loading and unloading. Therefore, the inability to mount a spare tire on this split tailgate can cause concern for users on long journeys, directly impacting the user experience. This is especially true for off-road vehicles, where users have a strong need for an externally mounted spare tire for emergencies such as tire blowouts while traversing challenging terrain.

[0033] Based on this, this application provides a split tailgate, which includes a first door and a second door, with the first door located above the second door. The first door is configured to rotate between a closed and an open position, with its rotating portion located on its side. The second door is configured to rotate between a closed and an open position, with its rotating portion located at its bottom. This configuration allows the first door to open laterally around its rotating portion, and the second door to open downwards around its rotating portion. Due to the side-rotating opening characteristic of the first door, it has a high load-bearing capacity. A spare tire can be externally mounted on the first door as needed; the added weight of the spare tire does not affect the load-bearing capacity of the first door during side rotation. Bags and other tools can also be externally mounted on the first door for convenient user access. Overall, this effectively improves the user experience. In particular, the above technical advantages are more significant for SUVs or off-road vehicles.

[0034] In addition, the first door opens slightly to the side, allowing passengers to easily access luggage from the trunk. This effectively prevents luggage from slipping out when parking on a slope, further enhancing the user experience.

[0035] Furthermore, based on the split tailgate structure provided in this application embodiment, it can also help enhance the safety of the escape mode. If the vehicle falls into water, a quick escape can be achieved by opening the first door alone.

[0036] To better understand the technical solution and effects of this application, specific embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figure 1 This is an isometric schematic diagram of a split tailgate provided in an embodiment of this application.

[0037] like Figure 1 As shown, the split tailgate 10 includes a first door 1 and a second door 2, with the first door 1 located above the second door 2. The first door 1 is configured to rotate between a closed and an open position, and its rotating portion (not shown) is located on the left side. The first door 1 can be opened by pulling a handle 4 located on the right side of its rotating portion. The second door 2 is configured to rotate between a closed and an open position, and its rotating portion (not shown) is located at its bottom. Here, "rotating portion" refers to the structure used to allow the corresponding door to rotate relative to the vehicle body and switch between the closed and open positions.

[0038] It should be understood that the directional terms such as "up," "down," "left," and "right" used in this document refer to the corresponding directional relationships perceived primarily by the vehicle driver. The use of these directional terms is only for clearly describing the scheme and does not constitute a substantial limitation on the scheme of this application.

[0039] In practical implementation, a spare tire 3 can be externally mounted on the first door 1 as needed for emergency situations such as tire blowouts. This technology offers particularly significant advantages in long-distance driving or off-road scenarios.

[0040] The split tailgate provided in this embodiment achieves lateral rotation opening of the first door 1 through a rotating part located on the side of the first door 1. The weight of the first door 1 and the externally mounted spare tire 3 is approximately parallel to its rotation center line, and will not generate torque affecting the open state of the first door 1. Thus, the load-bearing capacity requirements for the rotating part of the first door 1 and the related structures at the rear of the vehicle body will not become stringent due to the presence of the spare tire 3. Compared to the implementation scheme of split upper door rotating upward to open, if the externally mounted spare tire generates rotational torque in the rotation direction of the upper door, it is impossible to reliably achieve and guarantee the reliable opening state of the upper door. The embodiment of this application effectively reduces the impact of the spare tire 3 on the load-bearing capacity of the first door, and can reasonably control design and manufacturing costs.

[0041] In other specific implementations, hooks (not shown in the figure) can also be provided on the inner or outer side of the first door 1 to hang tools such as backpacks on the first door as needed for users to access and operate.

[0042] Please see also Figure 2 , Figure 3 and Figure 4 ,in, Figure 2 This is a schematic diagram illustrating one usage state of the split tailgate provided in an embodiment of this application. Figure 3 This is a schematic diagram of an open state provided in an embodiment of this application. Figure 4 This is a schematic diagram of another open state provided for an embodiment of this application.

[0043] Figure 2 The split tailgate 10 shown is in the closed position. In the closed state, the docking position of the first door 1 and the second door 2 can be formed according to the continuous appearance design requirements of the vehicle body. At the same time, the docking position of the entire split tailgate 10 with the rear outline of the vehicle body 20 is formed according to the continuous appearance design requirements of the vehicle body. The specific opening and closing mechanism and the door outline can be determined according to the overall design requirements of the vehicle. This application embodiment does not limit this.

[0044] Figure 3 The first door 1 shown is in the open position, and the second door 2 is in the closed position. It can be understood that opening the first door 1 is sufficient for loading and unloading small items. Furthermore, the first door 1 opens at a slight side angle, with the maximum opening for loading and unloading luggage from the trunk located on the side. This effectively prevents luggage from slipping out when parking on a slope, further enhancing the user experience.

[0045] Figure 4The first door 1 and the second door 2 shown are both in the open position. In practical applications, opening the second door 2 downwards reduces the difficulty of loading and unloading luggage, as well as the difficulty of passengers entering and exiting. In addition, in different scenarios such as camping or fishing, the open second door 2 can also be used as a control panel or seat, meeting the needs of different application scenarios.

[0046] To allow the first door 1 and the second door 2 to open sequentially, a rotation limit pair can be provided between the first door 1 and the second door 2 in a specific implementation. For example,... Figure 4 As shown, the second door 2 is provided with a limiting flange 21. In the closed state, the limiting flange 21 extends upward from the door body of the second door 2 and is located inside the first door 1 when it is in the closed position. Figure 3 As shown, in the closed state, the bottom end of the first door 1 forms a rotation limiting pair with the limiting protrusion 21 to restrict the rotation and opening of the second door 2. In this way, the first door 1 can be opened first, and then the second door 2 can be opened; conversely, the second door 2 can be closed first, and then the first door can be closed. Thus, the sequential opening and closing of the split tailgate can be achieved.

[0047] Of course, in other possible implementations, the rotation limiting pair between the first door 1 and the second door 2 can also be configured in the opposite direction. That is, the limiting protrusion can be located on the side of the first door 1 (not shown in the figure). Correspondingly, in the closed state, the limiting protrusion extends downward from the door body of the first door 1 and is located inside the second door 2 in the closed position, so as to restrict the first door 1 from rotating and opening. The specific implementation can be determined according to the overall product design requirements, and this application embodiment does not limit it.

[0048] In addition, for the first door 1 that opens by rotating to the side, the rotating part of the first door 1 can also be located on the right side. The first door 1 can be opened by pulling the handle located on the left side of the first door 1 around its right rotating part (not shown in the figure), rather than being limited to opening the first door 1 by rotating to the left.

[0049] Furthermore, to avoid the spare tire 3 obstructing the rear window, in the actual implementation, the height dimension L1 of the first door 1 can be greater than the height dimension L2 of the second door 2. Please refer to [the relevant documentation / reference]. Figure 5 , Figure 6 and Figure 7 ,in, Figure 5 for Figure 1 The front view of the split tailgate shown. Figure 6 This is an exploded view of the assembly of a split tailgate according to an embodiment of this application. Figure 7 for Figure 2 The side view shown depicts a split tailgate in use.

[0050] like Figure 5 As shown, the spare tire 3 can be positioned at the lower part of the first door 1, avoiding obstruction of the rear window 12 and allowing the driver to obtain a good rear view through the rear window 12. Simultaneously, the available space in the height direction can be fully utilized to arrange the rotating part of the first door 1, resulting in better rotational performance and load-bearing capacity.

[0051] For example, a tailgate window frame 111 is provided on the upper part of the door body 11 of the first door 1, and the rear window glass 12 is fixedly installed on the tailgate window frame 111. In other possible implementations, the rear window glass 12 may also be movably installed on the tailgate window frame 111. For example, but not limited to, the rear window glass 12 may include two pieces of glass, at least one of which can be slidably installed relative to the tailgate window frame 111 to open the rear window glass 12 as needed. The specific design can be determined according to the overall design requirements of the vehicle, and this application embodiment does not limit it.

[0052] Combination Figure 7 As shown, the height dimension L1 of the first door 1 can be greater than the height dimension L2 of the second door 2. Based on the determined rear opening of the vehicle body, on the one hand, there is space for a spare tire to be placed on the side of the first door 1, which can avoid the rear window, meeting emergency needs while ensuring the driver's rear visibility. On the other hand, the turning radius of the second door 2 is smaller (the turning trajectory is as shown in the diagram). Figure 7 As shown by the dashed line S, when the second door 2 is in the horizontally open state, the user is relatively close to the trunk when taking out or putting in luggage, which can effectively reduce the effort required to take out or put in luggage.

[0053] In the aforementioned embodiment, the first door 1 is an integral, side-rotating upper door. In other possible implementations, the first door 1 of the split tailgate 10 may include two side-opening sub-doors. Specifically, the left side of the left sub-door has a rotating part to allow it to rotate between a closed and open position, and the right side of the right sub-door has a rotating part to allow it to rotate between a closed and open position. Similarly, the spare tire may be externally mounted on either the left or right sub-door (not shown in the figure).

[0054] For the two side doors, the left and right side doors can be arranged symmetrically or asymmetrically. The specific arrangement can be determined based on the overall vehicle design requirements, and this embodiment does not impose such a limitation.

[0055] The specific implementation of other functional components can adopt the same structural form as the aforementioned embodiments. Further details will not be provided here.

[0056] In addition to the aforementioned split tailgate, this application also provides a vehicle that includes a tailgate located at the rear end of the vehicle body 20. This tailgate is a split tailgate 10 as described in the previous embodiments. Based on this split tailgate 10 structure, a spare tire or a backpack or other tools can be externally hung on the first door, facilitating emergency access for the user and effectively improving the user experience.

[0057] In practical implementation, the vehicle model using this split tailgate 10 can be an SUV or an off-road vehicle. For example, the vehicle can be a gasoline-powered vehicle, an electric vehicle, or a hybrid vehicle.

[0058] It should be understood that other functional components of the vehicle can be implemented based on existing technology, and therefore will not be elaborated further.

[0059] Furthermore, the ordinal numbers "first" and "second," etc., used herein are only for describing the composition or structure of the same function in the technical solution. It is understood that the use of the aforementioned ordinal numbers does not constitute a limitation on the understanding of the technical solution for which protection is sought in this application.

[0060] The above are merely preferred embodiments of the present invention.
