Obviously, the described embodiments are only some embodiments of this application, and not all 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.

[0042] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0043] Please see Figures 1-3 , Figure 1 This is a schematic diagram of a backdoor device provided in an embodiment of this application. Figure 1 (a) The rear door device includes a rear door panel 101 and a motion module.

[0044] In this embodiment, the motion module may include a first motion component 102, a second motion component 103, and a telescopic support 104. The first motion component 102 and the second motion component 103 may be rotatable and slidable motors, or rotatable pulleys.

[0045] In one optional embodiment, the first motion component 102 can be movably mounted on the rear door frame. There can be one or more first motion components 102. When there is only one first motion component 102, it can be positioned in the middle of the upper edge of the rear door frame. When there are multiple first motion components 102, they can be mounted on the left and right side frames of the rear door frame. The second motion component 103 can be movably mounted on the rear door panel 101. There can also be one or more second motion components 103. When there is only one second motion component 103, it can be positioned in the middle of the rear door panel 101. When there are multiple second motion components 103, they can be positioned on either side of the rear door panel 101. One end of the telescopic support 104 can be connected to the first motion component 102, and the other end can be connected to the second motion component 103. The telescopic support 104 can be a telescopic bracket or a foldable bracket. The number of telescopic support members 104 can be one or more. If there are multiple telescopic support members 104, then the multiple telescopic support members 104 should be connected one-to-one with multiple first motion components 102 and multiple second motion components 103.

[0046] The aforementioned telescopic support allows for the connection of a first motion component mounted on the rear door frame and a second motion component mounted on the rear door panel. In other words, by using the first motion component, the second motion component, and the telescopic support, the rear door panel can be separated from the vehicle body.

[0047] In one alternative embodiment, Figure 1 This is a schematic diagram of a backdoor device provided in an embodiment of this application. Figure 1 (a), such as Figure 1 As shown, at the first moment the rear door panel opens, that is, when the rear door panel 101 is in the position shown... Figure 1 When in the indicated state, the telescopic support 104 can extend, supporting the rear door panel 101 to leave the rear door frame and reach the first position. This first position can be a position where the rear door panel and the rear door frame are parallel to each other. The distance between the rear door panel and the rear door frame can be adjusted according to the distance between the rear of the vehicle and the obstacles behind it. Figure 2 This is a schematic diagram of a backdoor device provided in an embodiment of this application. Figure 1 (b), such as Figure 2 As shown, at the second moment when the rear door panel 101 is opened, that is, when the rear door panel 101 is in the... Figure 2In the indicated state, the second moving component 103 on the rear door panel 101 can slide downwards, and simultaneously, the rear door panel 101 can slide upwards to a second position under the action of the second moving component 103. This second position can be a position where the rear door panel is parallel to the plane of the rear door frame, and the lower edge of the rear door panel 101 can be in the same plane as the roof. After the rear door panel separates from the rear door frame, it moves upwards, achieving the purpose of opening the rear door while avoiding occupying a large amount of space behind the vehicle. Therefore, when the rear of the vehicle is too close to an obstacle behind it, the rear door panel can also be opened, making it convenient for the user to access items.

[0048] In one alternative embodiment, Figure 3 This is a schematic diagram of a backdoor device provided in an embodiment of this application. Figure 1 (c), such as Figure 3 As shown, a solar power generation layer can be installed on the rear door panel 101. This layer is applied during the third time the rear door panel 101 is opened, i.e., when the rear door panel 101 is in a certain position... Figure 3 In the indicated state, the first motion component 102 slides upwards, while the first motion component 102 and the second motion component 103 can rotate, thereby causing the rear door panel 101 to rotate to a position parallel to the plane of the vehicle roof, allowing the rear door panel to cover the roof. This way, the rear door panel does not occupy a large amount of space above the vehicle, while also maintaining the vehicle's aesthetics. When the vehicle is in a sunny outdoor environment, with the rear door panel covering the roof, the solar power generation layer on the rear door panel can fully receive sunlight, converting solar energy into electrical energy to charge the vehicle.

[0049] In one alternative embodiment, Figure 4 This is a schematic diagram of a first motion component provided in an embodiment of this application, as shown below. Figure 4 As shown, the first motion component 102 may include a first moving member 401 and a first slide rail 402. The first moving member 401 may be disposed in the first slide rail 402, which may be disposed on both sides of the rear door frame. The first slide rail may extend to the top of the vehicle, so that the rear door panel can be brought to the top of the vehicle as the first slide rail slides to the top of the vehicle.

[0050] In one alternative embodiment, Figure 5 This is a schematic diagram of a second motion component provided in an embodiment of this application, as shown below. Figure 5 As shown, the second motion component may include a second moving member 501 and a second slide rail 502. The second moving member 501 may be disposed in the second slide rail 502. The second slide rail 502 may be disposed on both sides of the rear door panel. The telescopic support member may connect the first moving member 401 and the second moving member 501, so that the rear door panel is separated from the rear door frame, and the rear door panel can also move.

[0051] The first slide rail allows the first moving part to slide or rotate within it. The second slide rail allows the second moving part to slide or rotate within it. After the telescopic support connects the first and second moving parts, the rear door panel can be separated from the rear door frame. The rear door panel is then driven by the first and second moving parts to reach the top of the vehicle. This allows the door to be opened even when the rear of the vehicle is very close to an obstacle, without taking up a large amount of space behind the vehicle.

[0052] In one alternative embodiment, Figure 6 This is a schematic diagram of a third motion component provided in an embodiment of this application, as shown below. Figure 6 As shown, the motion module may further include a third motion component, which may include a third moving member 601 and a bracket 602. The number of third moving members 601 and brackets 602 may be one or more. The third moving member 601 may be disposed within or near the second slide rail. When the third moving member 601 is disposed within the second slide rail, it is positioned above the second moving member 501 near the top of the second slide rail. One end of the bracket 602 may be connected to the third moving member 601. When the rear door panel leaves the rear door frame, the third moving member 601 can extend the bracket. When the rear door panel 101 covers the vehicle roof, the other end of the bracket 601 can contact the vehicle roof.

[0053] By setting up a third moving part and a bracket, the bracket supports the rear door panel when it covers the top of the vehicle. The bracket and the telescopic support work together to ensure the stability of the rear door panel on the roof.

[0054] In one alternative embodiment, Figure 7 This is a schematic diagram of a bracket provided in an embodiment of this application, as shown below. Figure 7As shown, bracket 701 can be a telescopic bracket. When the rear door panel 101 is open, bracket 701 can extend from a first length 702 to a second length 703 via the third moving member 601, allowing the other end of the bracket to contact the vehicle roof. The first length can be shorter than the second length. At the first length, the bracket is in a retracted state, saving space. Optionally, bracket 701 can be a folding bracket. When the rear door panel is open, bracket 701 can rotate from a first rotation position 704 to a second rotation position 705 via the third moving member 601. The first rotation position 704 can be a position where bracket 701 is parallel to the rear door panel 101, and the second rotation position 705 can be a position where bracket 701 is perpendicular to the rear door panel 101. When the bracket is not in use, it can rotate to a position parallel to the rear door panel, reducing obstruction during rear door panel movement. When the rear door panel covers the roof, the bracket can be adjusted to a position perpendicular to the rear door panel. In this way, the bracket and the telescopic support can jointly support the rear door panel, improving the stability of the rear door panel on the roof.

[0055] In one alternative embodiment, Figure 8 This is a schematic diagram of a horizontal sensing device provided in an embodiment of this application, as shown below. Figure 8 As shown, the level sensor 801 can be installed on the rear door panel or elsewhere on the vehicle, such as on the roof. The level sensor can be used to detect in real time whether the rear door panel, after covering the vehicle roof, remains parallel to the vehicle's roof surface.

[0056] By setting up a level sensor, it is possible to monitor in real time whether the rear door panel is parallel to the roof when it is covering the roof. If the rear door panel is always parallel to the roof, it can receive sufficient sunlight and is in the most stable state.

[0057] In this application embodiment, a vehicle is also provided, including the rear door device as described in the above embodiment.

[0058] In one alternative embodiment, Figure 9 This is a schematic diagram of a device on a vehicle provided in an embodiment of this application. Figure 1 ,like Figure 9 As shown, the vehicle may further include a processor 901 and an instruction receiving and control module 902. The processor 901 can send an instruction to the instruction receiving and control module 902 to open the rear door. The instruction receiving and control module 902 can be used to control the operation of the rear door device according to the rear door opening instruction sent by the processor 901.

[0059] With the cooperation of the processor and the instruction receiving and control module, the backdoor device can run smoothly.

[0060] In one alternative embodiment, Figure 10This is a schematic diagram of a device on a vehicle provided in an embodiment of this application. Figure 2 ,like Figure 10 As shown, the vehicle may further include a leveling module 1001. This module 1001 can acquire leveling information sent by the leveling sensor 801 after the rear door panel covers the vehicle roof. If the acquired leveling information meets preset requirements, the leveling module 1001 can send an adjustment command to the command receiving and control module 902. This adjustment command can be used to control the rear door device to adjust the length of the telescopic support until the length is sufficient for the rear door panel to be parallel to the roof. The leveling module helps ensure that the rear door panel is always parallel to the roof, thus ensuring the stability of the rear door panel when placed on the roof.
