DETAILED DESCRIPTION

[0041] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0042] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0043] The following combination Figures 1-13 A hatch assembly 10 for a vehicle 100 and the vehicle 100 having the hatch assembly 10 according to an embodiment of the present invention will be described in detail.

[0044] Reference Figures 1-6 As shown, vehicle 100 includes a body 20 having a cabin that can be used to store equipment or items, such as a drone 30 or a small vehicle. A door assembly 10 is mounted on body 20 and is used to open and close the cabin's hatch. For ease of description, the structure of door assembly 10 is described using a cabin that accommodates a drone 30, but this should not be construed as limiting the items that can be stored in the cabin.

[0045] Reference Figures 1-8 As shown, a hatch assembly 10 for a vehicle 100 according to an embodiment of the present invention may include a hatch 1 and a driving device.

[0046] The hatch 1 is movably mounted at the hatch opening of the cabin to open or close the hatch opening of the cabin, and the driving device is connected to the hatch 1 to drive the hatch 1 to open or close the hatch opening. Specifically, when the hatch 1 is in the open position, Figure 1 、 Figure 3-Figure 4 、 Figure 6-Figure 7 、 Figure 9-10 、 Figure 13 As shown, the cabin is exposed, which is convenient for releasing the drone 30; when the cabin door 1 is in the closed position, as shown Figure 2 、 Figure 5 、 Figure 8 、 Figure 11-12 As shown, the cabin is not visible from the outside of the vehicle 100, and the cabin door 1 can protect the internal environment of the cabin, prevent the drone 30 from being lost, and prevent external dust, debris, etc. from falling into the cabin.

[0047] It should be noted that the cabin can be the original space area inside the vehicle body 20, in which case the door 1 can be installed on the vehicle body 20 to open or close the cabin opening. The cabin can also be a physical component. For example, the cabin is a shell structure with a cabin opening, the shell structure is installed on the vehicle body 20, and the door 1 is installed on the shell structure to open or close the cabin opening.

[0048] Reference Figure 1 、 Figure 3-Figure 4 、 Figure 6 As shown, the projection of hatch door 1 on a plane perpendicular to the height of vehicle body 20 lies within the projection of vehicle body 20 on that plane. When vehicle 100 is placed on a horizontal road, the projection of hatch door 1 on the horizontal road lies within the projection of vehicle body 20 on the horizontal road. In other words, when hatch door 1 is open, it does not extend beyond the original length and width of vehicle body 20. This prevents hatch door 1 from interfering with surrounding vehicles, minimizing safety risks.

[0049] According to the hatch assembly 10 for the vehicle 100 according to the embodiment of the present invention, the hatch 1 does not exceed the length and width of the original body 20 of the vehicle 100 when in the open position, thereby avoiding interference between the hatch 1 and surrounding vehicles and helping to improve the safety of the vehicle 100.

[0050] In some embodiments, the driving device includes a transmission device 2 and a driving member 3, wherein the transmission device 2 includes a main connecting rod assembly 22, the main connecting rod assembly 22 is rotatably connected to the cabin door 1, and the driving member 3 is used to drive the main connecting rod assembly 22 to rotate to drive the cabin door 1 to open or close the cabin opening of the cabin.

[0051] Optionally, the driving member 3 is used to directly drive the main connecting rod assembly 22 to rotate, or it can indirectly drive the main connecting rod assembly 22 to rotate. The main connecting rod assembly 22 has low cost and reliable structure. Figure 7-13 In the example, the driving member 3 indirectly drives the main connecting rod assembly 22 to rotate through the gear assembly 21, thereby driving the cabin door 1 to move.

[0052] Optionally, the driving member 3 may be a motor, which drives the main connecting rod assembly 22 to rotate, so that the hatch assembly 10 has a high degree of automation, which can increase the technological sense of the vehicle 100.

[0053] Optionally, the driving member 3 may be fixed to the vehicle body 20 , so that the installation reliability of the driving member 3 is high.

[0054] According to an embodiment of the present invention, the hatch assembly 10 for the vehicle 100 drives the hatch 1 to open or close the hatch opening by providing a main connecting rod assembly 22, so that the movement trajectory of the hatch 1 is non-linear, and thus the hatch 1 does not exceed the original length and width of the vehicle body 20 of the vehicle 100 when in the open position, thereby avoiding interference between the hatch 1 and surrounding vehicles, which is beneficial to improving the safety of the vehicle 100.

[0055] In some embodiments of the present invention, reference Figure 7-13 As shown, the transmission device 2 includes a gear assembly 21 and a main connecting rod assembly 22. The drive member 3 is driven by the gear assembly 21, which in turn drives the main connecting rod assembly 22. The drive member 3 is adapted to rotate the gear assembly 21, thereby driving the main connecting rod assembly 22 to pull the hatch door 1. The gear assembly 21 reduces the speed of the drive member 3 and transmits it to the main connecting rod assembly 22, thereby ensuring smoother opening and closing of the hatch door 1 and enhancing safety.

[0056] In some embodiments of the present invention, reference Figure 7-Figure 8 、 Figure 10-13 As shown, the gear assembly 21 includes: a driving gear 211 and a driven gear 212. The driving member 3 is used to drive the driving gear 211 to rotate. The driven gear 212 is directly or indirectly meshed with the driving gear 211 for transmission. The main connecting rod assembly 22 is connected to the driven gear 212. When the driven gear 212 rotates, the main connecting rod assembly 22 is driven to rotate. Optionally, the driving shaft of the driving member 3 is fixedly connected to the driving gear 211. When the driving shaft rotates, the driving gear 211 rotates synchronously with the driving shaft, and the driving gear 211 drives the driven gear 212 to rotate.

[0057] In some embodiments of the present invention, the number of doors 1 is at least one, and the number of driven gears 212 and the number of main connecting rod assemblies 22 are equal to the number of doors 1. Each door 1 is rotatably connected to a corresponding main connecting rod assembly 22. For example, in some embodiments, the number of doors 1, the number of driven gears 212, and the number of main connecting rod assemblies 22 are all one. Or in Figures 1-13 In the example shown, the number of doors 1, the number of driven gears 212, and the number of main connecting rod assemblies 22 are all two. Of course, in some embodiments not shown in the figures, the number of doors 1, the number of driven gears 212, and the number of main connecting rod assemblies 22 may all be three, four, or more.

[0058] In some embodiments of the present invention, each main link assembly 22 includes a first link and a second link. One end of the first link is fixedly connected to a corresponding driven gear 212. The first link and the driven gear 212 are rotatably mounted to the vehicle body 20. One end of the second link is rotatably mounted to the vehicle body 20. The connection point between the first link and the vehicle body 20 is adapted to be separate from the connection point between the second link and the vehicle body 20. The other ends of the first link and the second link are each rotatably connected to different locations of the corresponding door 1. Specifically, the connection between the first link and the vehicle body 20 is rotatable, and the connection between the first link and the corresponding door 1 is rotatable. The first link is fixedly connected to the driven gear 212, and rotation of the driven gear 212 drives the first link to rotate. The connection between the second link and the vehicle body 20 is rotatable, and the connection between the second link and the corresponding door 1 is rotatable. When the driven gear 212 drives the first link to rotate, the second link rotates accordingly.

[0059] In some embodiments of the present invention, reference Figure 7-Figure 8 、 Figure 10-13 As shown, there are multiple driven gears 212, all of which rotate in the same direction. A single drive member 3 drives the multiple driven gears 212 to rotate in the same direction, thereby ensuring that the multiple main connecting rod assemblies 22 rotate in the same direction, thereby enabling simultaneous opening and closing of multiple doors 1. This transmission device 2 has a simple structure, low cost, and requires minimal modification to the vehicle body 20.

[0060] In some embodiments of the present invention, reference Figure 7-Figure 8 、 Figure 10-13 As shown, the axes of the driving gear 211 and the driven gear 212 are parallel, and the axial thickness of the driving gear 211 is not less than the sum of the axial thicknesses of all the driven gears 212 meshing with the driving gear 211 .

[0061] exist Figures 1-13In the example, there are two doors 1, the two doors 1 are the first door 11 and the second door 12, there are two main connecting rod assemblies 22, the two main connecting rod assemblies 22 are the first main connecting rod assembly 22a and the second main connecting rod assembly 22b, there are two driven gears 212, the two driven gears 212 are the first driven gear 2121 and the second driven gear 2122, the first main connecting rod assembly 22a includes a first group of first connecting rods 221a and a first group of second connecting rods 222a, one end of the first group of first connecting rods 221a is connected to the first group of second connecting rods 222b, and the first group of second connecting rods 221a is connected to the first group of second connecting rods 222a. A driven gear 2121 is fixedly connected. The first group of first connecting rods 221a and the first driven gear 2121 are rotatably mounted on the vehicle body 20. One end of the first group of second connecting rods 222a is rotatably mounted on the vehicle body 20. The connection point between the first group of first connecting rods 221a and the vehicle body 20 is adapted to be separated from the connection point between the first group of second connecting rods 222a and the vehicle body 20. The other ends of the first group of first connecting rods 221a and the other ends of the first group of second connecting rods 222a are both rotatably connected to different positions of the corresponding hatch 1. When the first driven gear 2121 rotates, it can drive the first group of first connecting rods 221a to rotate. When the first group of first connecting rods 221a rotates, it can also drive the first group of second connecting rods 222a to rotate, thereby causing the first group of first connecting rods 221a and the first group of second connecting rods 222a to drive the first hatch 11 to move.

[0062] Similarly, the second main link assembly 22b includes a second set of first links 221b and a second set of second links 222b. One end of the second set of first links 221b is fixedly connected to the second driven gear 2122. The second set of first links 221b and the second driven gear 2122 are rotatably mounted on the vehicle body 20. One end of the second set of second links 222b is rotatably mounted on the vehicle body 20. The connection point between the second set of first links 221b and the vehicle body 20 is adapted to be separated from the connection point between the second set of second links 222b and the vehicle body 20. The other ends of the second set of first links 221b and the other ends of the second set of second links 222b are rotatably connected to different positions of the corresponding hatch 1. Rotation of the second driven gear 2122 drives rotation of the second set of first links 221b, which in turn drives rotation of the second set of second links 222b, thereby causing the second set of first links 221b and the second set of second links 222b to drive movement of the second hatch 12.

[0063] Reference Figures 1-13 As shown, the first door 11 can be located above the second door 12. In an embodiment not shown in the figure, the first door 11 and the second door 12 can be arranged left and right, for example, the first door 11 is close to the driver's side, the second door 12 is close to the co-pilot side, the first door 11 is located to the left of the second door 12, the first door 11 opens to the left, and the second door 12 opens to the right.

[0064] Reference Figure 7-Figure 8 、 Figure 10-13 As shown, the axes of the driving gear 211, the first driven gear 2121, and the second driven gear 2122 are parallel. The driving gear 211 meshes with the first driven gear 2121, and the driving gear 211 also meshes with the second driven gear 2122. Rotation of the driving gear 211 drives the first and second driven gears 2121, 2122, so that the first and second driven gears 2121, 2122 rotate in the same direction. As a result, the two main connecting rod assemblies 22 rotate in the same direction, allowing the first and second doors 11, 12 to open or close simultaneously.

[0065] The driving gear 211 has the same module as the first driven gear 2121 and the second driven gear 2122, but different axial thicknesses. The first driven gear 2121 and the second driven gear 2122 have the same number of teeth, module, and axial thickness. The axial thicknesses of the first driven gear 2121 and the second driven gear 2122 are both smaller than the axial thickness of the driving gear 211. In this way, the first driven gear 2121 and the second driven gear 2122 can engage with different axial positions of the driving gear 211, so that the first driven gear 2121 can be staggered with the second driven gear 2122 in the axial direction of the driving gear 211, thereby staggering the positions of the first main connecting rod assembly 22a and the second main connecting rod assembly 22b in the axial direction of the driving gear 211 to avoid motion interference. For example, in some embodiments, the axial thicknesses of the first driven gear 2121 and the second driven gear 2122 are equal, and the axial thickness of the driving gear 211 is twice the axial thickness of the first driven gear 2121 (or the second driven gear 2122 ).

[0066] The first driven gear 2121 and the second driven gear 2122 directly receive the transmission from the driving gear 211 , which can reduce power loss.

[0067] The transmission ratio of the driving gear 211 to the first driven gear 2121 is the same as the transmission ratio of the driving gear 211 to the second driven gear 2122 , ensuring synchronous rotation of the first driven gear 2121 and the second driven gear 2122 when the driving gear 211 rotates.

[0068] The first driven gear 2121 drives the first group of first connecting rods 221 a to rotate, and the first group of first connecting rods 221 a drives the first cabin door 11 and the first group of second connecting rods 222 a to move, thereby realizing the opening and closing movement of the first cabin door 11 .

[0069] The second driven gear 2122 drives the second group of first connecting rods 221 b to rotate, and the second group of first connecting rods 221 b drives the second door 12 and the second group of second connecting rods 222 b to move, thereby realizing the opening and closing movement of the second door 12 .

[0070] The synchronous rotation of the first driven gear 2121 and the second driven gear 2122 drives the first hatch 11 and the second hatch 12 to open and close synchronously. Through the above method, a single motor drives the two hatches 1 to open and close synchronously.

[0071] The original rear window of vehicle 100 is now used as the hatch opening. Both hatches 1 open toward the rear of vehicle 100, effectively dividing the rear window into two sections. A four-link folding door design reduces the unfolded dimensions of the two doors 1, while also ensuring a reliable structure for the door assembly 10. Furthermore, when opened, the doors 1 occupy minimal space, remaining within the boundaries of vehicle body 20 and preventing accidents.

[0072] In some embodiments of the present invention, the driving member 3 is suitable for directly driving the main connecting rod assembly 22 to rotate, so as to drive the cabin door 1 to move. The number of cabin door 1 is at least one, and the number of main connecting rod assemblies 22 is equal to the number of cabin doors 1. Each cabin door 1 is rotatably connected to the corresponding main connecting rod assembly 22. For example, the number of cabin doors 1 and the number of main connecting rod assemblies 22 are both one; or, the number of cabin doors 1 and the number of main connecting rod assemblies 22 are both two. Of course, the number of cabin doors 1 and the number of main connecting rod assemblies 22 can both be three, four or more. Each main connecting rod assembly 22 includes a first connecting rod and a second connecting rod, one end of the first connecting rod is fixedly connected to the drive shaft of the driving member 3, one end of the second connecting rod is rotatably mounted on the vehicle body 20, and the other end of the first connecting rod and the other end of the second connecting rod are both rotatably connected to different positions of the corresponding cabin door 1.

[0073] In some embodiments of the present invention, the door 1 includes a door body and a door support plate, the door support plate is fixedly connected to the door body, and the main connecting rod assembly 22 is rotatably connected to the door support plate. Specifically, the connection between the first connecting rod and the corresponding door support plate is rotatable, and the connection between the second connecting rod and the corresponding door support plate is rotatable. The first door 11 and the second door 12 both include a door body and a door support plate. The door support plate can be located below the door body. In this way, the door body can cover the door support plate, making the appearance of the door 1 more beautiful. The door support plate and the door body can be made of different materials or the same material. For example, the door support plate is a steel plate and the door body is a plastic plate. This can save costs and does not affect the connection strength between the door support plate and the main connecting rod assembly 22.

[0074] Reference Figure 11 As shown, the first door 11 includes a first door body 111 and a first door support plate 112. The first door support plate 112 is located below the first door body 111. The connection between the first group of first connecting rods 221a and the first door support plate 112 can rotate, and the connection between the first group of second connecting rods 222a and the first door support plate 112 can rotate.

[0075] Reference Figure 11 As shown, the second door 12 includes a second door body 121 and a second door support plate 122. The second door support plate 122 is located below the second door body 121. The connection between the second group of first connecting rods 221b and the second door support plate 122 is rotatable, and the connection between the second group of second connecting rods 222b and the second door support plate 122 is rotatable.

[0076] In some embodiments of the present invention, the hatch assembly 10 further includes an auxiliary link assembly 23. The main link assembly 22 and the drive member 3 are located at one end of the hatch 1 in the transverse direction of the vehicle 100, and the auxiliary link assembly 23 is located at the other end of the hatch 1 in the transverse direction of the vehicle 100. The auxiliary link assembly 23 includes a third link and a fourth link. One end of the third link and one end of the fourth link are both rotatably mounted to different positions of the vehicle body 20, and the other ends of the third link and the other ends of the fourth link are both rotatably connected to different positions of the corresponding hatch 1. Specifically, the connection between the third link and the vehicle body 20 is rotatable, the connection between the third link and the corresponding hatch support plate is rotatable, the connection between the fourth link and the vehicle body 20 is rotatable, and the connection between the fourth link and the corresponding hatch support plate is rotatable.

[0077] exist Figure 7-13 In the example, there are two doors 1, the two doors 1 are the first door 11 and the second door 12, there are two auxiliary link assemblies 23, the two auxiliary link assemblies 23 are the first auxiliary link assembly 23a and the second auxiliary link assembly 23b, the first auxiliary link assembly 23a includes a first group of third links 231a and a first group of fourth links 232a, one end of the first group of third links 231a and one end of the first group of fourth links 232a are rotatably mounted on different positions of the vehicle body 20, and the other end of the first group of third links 231a and the other end of the first group of fourth links 232a are both rotatably connected to different positions of the first door 11. Similarly, the second auxiliary link assembly 23b includes a second group of third links 231b and a second group of fourth links 232b, one end of the second group of third links 231b and one end of the second group of fourth links 232b are rotatably mounted at different positions of the vehicle body 20, and the other end of the second group of third links 231b and the other end of the second group of fourth links 232b are both rotatably connected to different positions of the second hatch 12.

[0078] In some embodiments of the present invention, reference Figure 12-13As shown, the door assembly 10 also includes a first limiting structure 4 and a second limiting structure 5, both of which are located in the cabin, and the second limiting structure 5 is located on the side of the first limiting structure 4 close to the cabin opening. The first link and the second link of each main link assembly 22 are suitable for rotating between the corresponding first limiting structure 4 and the second limiting structure 5, and the first limiting structure 4 is used to limit the first extreme position of the first link, and the second limiting structure 5 is used to limit the second extreme position of the second link.

[0079] exist Figure 12-13 In the example, there are two doors 1, namely the first door 11 and the second door 12. There are two main connecting rod assemblies 22, namely the first main connecting rod assembly 22a and the second main connecting rod assembly 22b. There are two first limiting structures 4, namely the first group of first limiting structures 4a and the second group of first limiting structures 4b. There are two second limiting structures 5, namely the first group of second limiting structures 5a and the second group of second limiting structures 5b. The first group of first connecting rods 221a and the first group of second connecting rods 222a are adapted to rotate between the first group of first limiting structures 4a and the first group of second limiting structures 5a. The first group of first limiting structures 4a is used to limit the first group of first connecting rods 221a to the first extreme position, and the first group of second limiting structures 5a is used to limit the first group of second connecting rods 222a to the second extreme position. The second group of first connecting rods 221b and the second group of second connecting rods 222b are suitable for rotating between the second group of first limiting structures 4b and the second group of second limiting structures 5b, and the second group of first limiting structures 4b are used to limit the first extreme position of the second group of first connecting rods 221b, and the second group of second limiting structures 5b are used to limit the second extreme position of the second group of second connecting rods 222b.

[0080] like Figure 12 As shown, when the hatch 1 is closed, the first set of first limiting structures 4a restricts the freedom of the first set of first connecting rods 221a, while the second set of first limiting structures 4b restricts the freedom of the second set of first connecting rods 221b. This ensures the closing accuracy of the hatch 1 and reduces the shaking of the connecting rods, thus achieving the dual-degree-of-freedom mechanical clearance offset.

[0081] like Figure 13As shown, when the hatch 1 is opened, the first set of second limiting structures 5a restricts the degrees of freedom of the first set of second connecting rods 222a, while the second set of second limiting structures 5b restricts the degrees of freedom of the second set of second connecting rods 222b. This ensures high opening precision of the hatch 1, minimizes wobbling of the connecting rods, and achieves dual-degree-of-freedom mechanical clearance cancellation. In other words, the two sets of first limiting structures 4 and the two sets of second limiting structures 5 achieve dual-degree-of-freedom mechanical clearance cancellation, effectively eliminating wobbling caused by movement, and making the hatch assembly 10 structurally stable and simple.

[0082] In some embodiments of the present invention, the driving shaft of the driving member 3 stops rotating after the gap between the connecting rod and the corresponding limiting structure is zero, thereby preventing the driving member 3 from being damaged.

[0083] Optionally, refer to Figure 12-13 As shown, the first limiting structure 4 and the second limiting structure 5 can be constructed as a limiting bar structure with a limiting groove and a "U" cross-section. After the gap between the connecting rod and the corresponding limiting structure is zero, the connecting rod is wrapped in multiple directions by the groove wall of the limiting groove, which can prevent the connecting rod from shaking.

[0084] Reference Figures 1-6 As shown, a vehicle 100 according to another embodiment of the present invention includes the hatch assembly 10 of the above embodiment.

[0085] In some embodiments of the present invention, reference Figure 4 As shown, the vehicle 100 has a storage board 40 behind the rear seats 50, and the engine room is located above the storage board 40, so that the vehicle space can be reasonably utilized without affecting the driver's front and side vision.

[0086] In some embodiments of the present invention, reference Figure 4 、 Figure 6-Figure 7 As shown, a drone parking plate 60 can be provided above the storage plate 40. The drone parking plate 60 is placed on the storage plate 40, and the drone 30 is suitable for parking on the drone parking plate 60. Optionally, a centering structure can be provided on the drone parking plate 60 to adjust the position of the drone 30 so that the drone 30 is in the middle position on the drone parking plate 60. The drone parking plate 60 can also be provided with a guide rail to guide the movement of the drone 30 on the drone parking plate 60.

[0087] When the cabin is an existing space within the vehicle body 20, the space above the shelf 40 forms the cabin, and the drone parking plate 60 is located within the cabin. When the cabin is a physical component, the cabin is placed above the shelf 40, and the drone parking plate 60 is located within the cabin, or the drone parking plate 60 forms the floor of the cabin.

[0088] According to the vehicle 100 according to the embodiment of the present invention, its hatch assembly 10 drives the hatch 1 to open or close the hatch opening by setting a main connecting rod assembly 22, so that the movement trajectory of the hatch 1 is non-linear, and thus the hatch 1 does not exceed the original length and width of the vehicle body 20 of the vehicle 100 when in the open position, thereby avoiding interference between the hatch 1 and surrounding vehicles, which is beneficial to improving the safety of the vehicle 100.

[0089] In some embodiments of the present invention, the cabin is located behind the rear seats 50 of the vehicle 100. The vehicle body 20 includes a trunk lid. When the hatch 1 opens the hatch opening of the cabin, the hatch 1 is located above the trunk lid. When the hatch 1 is open, it does not extend beyond the original length and width of the vehicle body 20. The hatch 1 is located within the circumferential boundaries of the vehicle body 20. When opened, the hatch 1 does not extend beyond the boundaries of the vehicle body 20, and the hatch 1 does not affect the original wind resistance of the vehicle 100.

[0090] In some embodiments of the present invention, reference Figures 1-6 As shown, multiple doors 1 are stacked above the trunk lid when the doors 1 open the hatch opening. When the doors 1 close the hatch opening, the doors 1 are adjacent. The hatch opening is located where the rear window of vehicle 100 once was. The driver 3 drives the main link assembly 22 to open and close the multiple doors 1. When the hatch opening is closed, the doors 1 align with the rear window. This maintains the appearance of vehicle body 20, does not affect the functionality of vehicle 100, and does not impair the driver's forward and side vision.

[0091] exist Figure 2 and Figure 5 In the example, there are two hatches 1, namely a first hatch 11 and a second hatch 12. When the hatches 1 are closed, the first hatch 11 and the second hatch 12 are attached to the vehicle body 20, and are consistent with the original rear window of the vehicle 100, without affecting the original appearance and field of view of the vehicle 100.

[0092] In some embodiments of the present invention, when the hatch 1 is opened to the maximum position, the hatch 1 is parallel to the trunk lid. Figure 1 、 Figure 3 、 Figure 6 In the example, there are two doors 1, namely a first door 11 and a second door 12. When the two doors 1 are opened, the second door 12 is positioned above the trunk lid, and the first door 11 is positioned above the second door 12. The first and second doors 11 and 12 are stacked one on top of the other. This helps reduce wind resistance of the vehicle 100 and ensures the safety of the doors 1 when opened while the vehicle 100 is in operation. Furthermore, the folding door design reduces the area occupied by the doors 1 when opened. When opened, the doors 1 do not extend beyond the boundaries of the vehicle body 20, thus not affecting the driver's field of view.

[0093] Reference Figure 1 、 Figure 3 、 Figure 6 As shown, after the two doors 1 are opened, the first door 11 and the second door 12 can be parallel to the trunk lid, thereby further reducing the area occupied by the doors 1 after opening.

[0094] Reference Figure 1 、 Figure 3 、 Figure 6 As shown, after the hatch 1 is opened, there is no interference with the drone 30, and the drone 30 can take off normally. At the same time, the tail of the hatch 1 does not exceed the boundary of the vehicle body 20.

[0095] When the vehicle 100 is traveling, the hatch 1 is opened, and the airflow contacts the hatch 1 similarly to line contact, with a small contact area, thereby reducing wind resistance and improving the safety of the hatch 1.

[0096] According to the vehicle 100 of the embodiment of the present invention, the hatch assembly 10 thereof can reasonably utilize the space of the vehicle 100 without affecting the driver's field of vision.
