[0066] It should be understood that in this application, "connection" and "connected" can both refer to a mechanical connection or a physical connection. That is, A and B being connected or A and B being connected can mean that there are fastened components (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and A and B are difficult to separate.

[0067] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0068] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0069] On the one hand, combined with Figures 1 to 5 As shown, this embodiment provides a tailgate device 100, which includes a tailgate assembly 1, a movable tailgate 2, and a sliding assembly 3.

[0070] The tailgate assembly 1 is connected to the rear end of the movable tail compartment 2. The movable tail compartment 2 is connected to the sliding assembly 3. The sliding assembly 3 is used to slide the movable tail compartment 2 to the rear end of the vehicle body 200. The movable tail compartment 2 can slide and extend towards the rear of the vehicle body 200 to increase or decrease the interior space of the vehicle body 200.

[0071] In this embodiment, the tailgate device 100 uses a sliding component 3 to slidably connect the movable tail compartment 2 to the rear end of the vehicle body 200. The movable tail compartment 2 causes the tailgate component 1 to extend or retract towards the rear of the vehicle body 200. Since the position of the tailgate component 1 directly affects the size of the interior space of the vehicle body 200, when the movable tail compartment 2 causes the tailgate component 1 to extend backward, the interior space of the vehicle body 200 can be expanded. The expanded space is actually the part of the movable tail compartment 2 that extends. When the movable tail compartment 2 causes the tailgate component 1 to retract, the interior space of the vehicle body 200 returns to a state corresponding to the size of the vehicle body 200. Therefore, the extension or retraction of the tailgate device 100 of this application can change the size of the interior space of the vehicle body 200, thereby making the vehicle using this tailgate device 100 suitable for different usage scenarios.

[0072] In some possible implementations, the tailgate assembly 1 is located at the rear of the vehicle body 200 and is able to close the interior space of the vehicle body 200.

[0073] In some possible implementations, the movable tail compartment 2 and the vehicle body 200 are connected by a movable sealed connection, which ensures both a sliding connection between the movable tail compartment 2 and the vehicle body 200 and provides a seal to prevent rainwater from entering the interior space of the vehicle body 200. Optionally, a sealing element such as a rubber sealing ring is provided between the movable tail compartment 2 and the vehicle body 200.

[0074] In some possible implementations, the movable tailgate 2 can be made of the same material as the vehicle body 200, or it can be made of a different material. In some examples, the movable tailgate 2 is made of sheet metal, which provides better structural strength while also enhancing the aesthetics. In other examples, the movable tailgate 2 is partially or entirely made of transparent materials, such as tempered glass or transparent plastic, which, when the movable tailgate 2 is extended, provides better visibility and lighting within the vehicle body 200.

[0075] In some possible implementations, when the movable tailgate 2 is fully retracted into the vehicle body 200, the tailgate device 100 is in its first state. At this time, the tailgate assembly 1 is directly connected to the rear end of the vehicle body 200. The interior space of the vehicle body 200 is enclosed by the vehicle body 200 and the tailgate assembly 1, and its length in the front-to-back direction is determined by the length of the vehicle body 200. In this state, the vehicle's front-to-back length (or head-to-tail distance) is smaller, providing better maneuverability, better passability, and easier parking.

[0076] When the movable tailgate 2 extends towards the rear of the vehicle body 200, the tailgate assembly 100 is in its second state. At this time, the tailgate assembly 1 is separated from the rear of the vehicle body 200 and is located behind the vehicle body 200. The interior space of the vehicle body 200 is formed by the vehicle body 200, the movable tailgate 2, and the tailgate assembly 1. Its length in the front-to-back direction is determined by the length of the vehicle body 200 plus the length of the movable tailgate 2, thus gaining additional space provided by the movable tailgate 2. In this state, the vehicle has a larger front-to-back length, resulting in a larger interior space. This provides users with more space, such as accommodating more passengers, loading longer or more numerous cargo items, and providing a more spacious leisure area where users can lie down and rest.

[0077] Combination Figure 1 and Figure 2 As shown, in some embodiments, the rear end of the vehicle body 200 is open, and at least a portion of the movable tailgate 2 is located inside the vehicle body 200.

[0078] With the above arrangement, since at least part of the movable tailgate 2 is located inside the vehicle body 200, the movable tailgate 2 can be reliably slidably connected to the rear end of the vehicle body 200. In the retracted state, the movable tailgate 2 can be completely wrapped by the vehicle body 200, and the tailgate assembly 1 can be directly connected to the rear end of the vehicle body 200. The vehicle body 200 has better integrity and the vehicle has a better appearance.

[0079] In addition, at least part of the movable tail compartment 2 is located inside the vehicle body 200, and the vehicle body 200 can also provide necessary protection for the movable tail compartment 2.

[0080] Combination Figure 5 As shown, in some embodiments, the movable rear compartment 2 is provided with a rear compartment space 201, the front end of which is open; the vehicle body 200 is provided with a vehicle body space 2001, the rear end of which is open.

[0081] The front end of the trunk space 201 is connected to the rear end of the body space 2001, and at least a portion of the trunk space 201 is located within the body space 2001.

[0082] With the above arrangement, the trunk space 201 inside the movable trunk 2 is connected to the body space 2001 inside the body 200. When the movable trunk 2 extends toward the rear end of the body 200, the trunk space 201 can expand the body space 2001, increase the volume of the body space 2001, meet the needs of large space use, and improve the applicability of the vehicle.

[0083] Combination Figures 1 to 5As shown, in some embodiments, the movable tail compartment 2 includes a tail compartment top plate 21, a tail compartment bottom plate 22, and two tail compartment side plates 23; the tail compartment top plate 21 and the tail compartment bottom plate 22 are arranged vertically, and the two tail compartment side plates 23 are arranged at intervals between the tail compartment top plate 21 and the tail compartment bottom plate 22, so that the tail compartment top plate 21, the tail compartment bottom plate 22, and the two tail compartment side plates 23 form a circumferentially enclosed tail compartment space 201.

[0084] With the above arrangement, the movable tail compartment 2 utilizes the tail compartment top plate 21, tail compartment bottom plate 22 and two tail compartment side plates 23 to form a circumferentially sealed tail compartment space 201. The front end of the tail compartment space 201 is open and connected to the vehicle body space 2001, and the rear end of the tail compartment space 201 can be closed by the tailgate assembly 1.

[0085] Combination Figures 1 to 5 As shown, in some embodiments, the vehicle body 200 includes a roof panel 51, a floor panel 52, and two side panels 53; the roof panel 51 and the floor panel 52 are arranged vertically, and the two side panels 53 are arranged at intervals between the roof panel 51 and the floor panel 52, so that the roof panel 51, the floor panel 52, and the two side panels 53 form a circumferentially enclosed vehicle body space 2001.

[0086] With the above arrangement, the body 200 utilizes the body roof plate 51, body floor plate 52 and two body side plates 53 to form a circumferentially sealed body space 2001. The rear end of the body space 2001 is open and connected to the tail compartment space 201, forming an internal space that can be extended and retracted in the front and rear.

[0087] Combination Figure 5 As shown, in some embodiments, when the movable tail compartment 2 includes a tail compartment floor 22 and the vehicle body 200 includes a vehicle body floor 52, the tail compartment floor 22 and the vehicle body floor 52 are slidably connected by a sliding component 3.

[0088] With the above arrangement, the tailgate floor 22 of the movable tailgate 2 and the body floor 52 of the vehicle body 200 can be slidably connected by the sliding assembly 3. The body floor 52 can not only provide upward support for the tailgate floor 22 and the entire tailgate device 100, but also provide guidance and limit for the forward and backward sliding of the movable tailgate 2.

[0089] Combination Figure 6 As shown, in some embodiments, when the movable tail compartment 2 includes two tail compartment side panels 23 and the vehicle body 200 includes two vehicle body side panels 53, each tail compartment side panel 23 is slidably connected to the corresponding vehicle body side panel 53 via a sliding component 3.

[0090] With the above arrangement, the side panel 23 of the movable tail compartment 2 and the side panel 53 of the body 200 can be slidably connected by the sliding assembly 3. The side panel 53 can provide horizontal support for the tail compartment floor 22 and the entire tailgate device 100, reduce the horizontal swaying of the movable tail compartment 2, and improve the reliability and stability of the connection between the movable tail compartment 2 and the body 200.

[0091] Combination Figures 7 to 9 As shown, in some embodiments, the tailgate assembly 1 is located at the rear end of the tailgate device 100. The tailgate assembly 1 includes a tailgate frame 11 and a vent 12. The tailgate frame 11 is connected to the rear end of the movable tailgate 2, and the vent 12 is movably connected to the tailgate frame 11. The vent 12 can be opened or closed.

[0092] In this embodiment, the tailgate assembly 1 serves as a closing component at the rear end of the movable tailgate 2, and also as a closing component at the rear end of the vehicle body 200. It has a tailgate frame 11, which is connected to the rear end of the movable tailgate 2 and can reinforce the rear end of the movable tailgate 2. At the same time, the tailgate frame 11 can also facilitate the movable connection of the windshield 12, which can be opened or closed, serving as a rear window of the vehicle's interior space.

[0093] It should be noted that the windshield 12 can also be called the tailgate or rear window. This windshield 12 can have a significant impact on the driver's visibility, passenger comfort, aesthetics, and aerodynamic characteristics.

[0094] In some embodiments, the opening method of the windshield 12 includes any one of the following: upward opening, downward opening, side opening, segmented opening, and double opening.

[0095] When the windshield 12 opens upwards, refer to Figure 8 As shown, the top edge of the windshield 12 is movably connected to the top frame of the tailgate frame 11, allowing the windshield 12 to be lifted upwards and opened. When the windshield 12 opens downwards, the bottom edge of the windshield 12 is movably connected to the bottom frame of the tailgate frame 11, allowing the windshield 12 to be flipped downwards and opened. When the windshield 12 opens to the side, refer to... Figure 7 As shown, one edge of the vent 12 is movably connected to the side frame of the tailgate frame 11, allowing the vent 12 to be flipped open to the horizontal. When the vent 12 opens in a segmented or bi-fold manner, it can have at least two sub-windows. These sub-windows can be arranged vertically side-by-side or horizontally side-by-side, and each sub-window is movably connected to its corresponding tailgate frame 11. Taking two sub-windows as an example, each sub-window is connected to two opposite positions on the tailgate frame 11, such as the top and bottom frames, or the two side frames. The vent 12 can then open vertically or horizontally (see reference). Figure 9(As shown). If the two child windows are not connected in opposite positions, for example, the lower child window is movably connected to the bottom frame of the tailgate frame 11, and the upper child window is movably connected to the side frame of the tailgate frame 11, the opening method of the vent 12 is a segmented type of bottom opening + side opening.

[0096] In some possible implementations, the windshield 12 is hinged to the tailgate frame 11, and a sealing mechanism, a support mechanism and a window locking device are provided between the windshield 12 and the tailgate frame 11.

[0097] In some possible implementations, the vent 12 can be opened or closed at any position where the movable rear compartment 2 extends or retracts, making it convenient for users to use the vent 12 in different scenarios, such as making it convenient for users to retrieve or place items from the rear.

[0098] In some other possible implementations, the opening or closing of the windshield 12 can be achieved manually or electrically. For example, in electric drive mode, the opening or closing commands for the windshield 12 include, but are not limited to, the vehicle's electronic display, switches, smart keys, mobile apps, and voice commands. Another example is that the windshield 12 also features an anti-pinch function.

[0099] Combination Figures 7 to 9 As shown, in some embodiments, the tailgate assembly 1 further includes a ring taillight 13, the shape of which corresponds to the shape of the tailgate frame 11, and the ring taillight 13 is disposed on the rear end surface of the tailgate frame 11.

[0100] With the above arrangement, the ring-shaped taillights 13 are arranged on the rear end face of the tailgate frame 11, which can make the rear of the vehicle present a simple and elegant appearance.

[0101] Combination Figure 6 As shown, in some embodiments, the vehicle body 200 includes an outer body panel 54 and an interior panel 55. The outer body panel 54 forms a vehicle body space 2001, and the interior panel 55 covers the inner side of the outer body panel 54. The movable tailgate 2 is slidably connected between the outer body panel 54 and the interior panel 55.

[0102] With the above arrangement, the movable tailgate 2 is slidably connected between the outer body panel 54 and the interior panel 55. The movable tailgate 2 is not directly visible from either the outside or inside of the vehicle body 200, ensuring a good appearance and visual effect. Furthermore, the movable tailgate 2 poses a certain safety hazard during its sliding process. By placing the movable tailgate 2 between the outer body panel 54 and the interior panel 55, the movable area is isolated from the sliding area of ​​the movable tailgate 2, providing better safety protection.

[0103] Since the movable tail compartment 2 is located between the outer body panel 54 and the interior panel 55, the sliding component 3 must also be located between the outer body panel 54 and the interior panel 55. The working space of the sliding component 3 is close to a sealed space, so there is no need to worry about debris, dust, rainwater, etc. entering. The working reliability and stability of the sliding component 3 can also be guaranteed.

[0104] In some possible implementations, the roof panel 51 and the two side panels 53 respectively include the aforementioned outer body panel 54 and interior panel 55, the rear cargo box roof panel 21 is located between the outer body panel 54 and interior panel 55 forming the roof panel 51, and the rear cargo box side panel 23 is located between the outer body panel 54 and interior panel 55 forming the side panel 53. Figure 6 This diagram illustrates the connection relationship between the rear cargo box side panel 23 and the body side panel 53 when the body side panel 53 includes the aforementioned body outer panel 54 and interior panel 55.

[0105] It should be noted that the vehicle body floor 52 can also be formed by the vehicle body outer panel 54 and the interior panel 55. In this case, the interior panel 55 forms the floor of the vehicle body space 2001.

[0106] Combination Figure 5 , Figure 6 ,as well as Figure 10 and Figure 11 As shown, in some embodiments, the sliding component 3 includes a first sliding member 31 and a second sliding member 32. The first sliding member 31 is fixedly connected to the movable tail compartment 2, and the second sliding member 32 is fixedly connected to the vehicle body 200. The first sliding member 31 and the second sliding member 32 are slidably connected.

[0107] With the above arrangement, the movable tail compartment 2 is fixedly connected to the first sliding member 31, and the body 200 is fixedly connected to the second sliding member 32. The first sliding member 31 and the second sliding member 32 can be slidably connected, thereby realizing the slidable connection between the movable tail compartment 2 and the body 200.

[0108] Among some possible implementations, refer to Figure 5 and Figure 6 As shown, the first sliding member 31 is a slider structure, and the second sliding member 32 is a slide rail structure. The second sliding member 32 is arranged along the front-rear direction of the vehicle, and the first sliding member 31 can slide back and forth along the second sliding member 32, thereby realizing the extension or retraction of the movable tail compartment 2 toward the rear end of the vehicle body 200. For example, the number of first sliding members 31 can be at least two, arranged at intervals, to provide balanced support for the movable tail compartment 2.

[0109] It should be noted that the first sliding member 31 can also be a slide rail structure, and the second sliding member 32 can also be a slider structure. This application does not impose too many restrictions on this.

[0110] Among some possible implementations, refer to Figure 10 and Figure 11 As shown, the first sliding member 31 is a nut structure, and the second sliding member 32 is a screw structure (or lead screw structure). The second sliding member 32 is arranged along the longitudinal direction of the vehicle, and the first sliding member 31 is threadedly connected to the second sliding member 32. When the second sliding member 32 rotates, the first sliding member 31 can slide back and forth along it, thereby enabling the movable tailgate 2 to extend or retract towards the rear end of the vehicle body 200. For example, the number of first sliding members 31 can be at least two, arranged at intervals to provide balanced support for the movable tailgate 2.

[0111] It should be noted that the first sliding member 31 can also be a screw structure, and the second sliding member 32 can also be a nut structure. This application does not impose too many restrictions on this.

[0112] Combination Figure 10 and Figure 11 As shown, in some embodiments, the tailgate device 100 further includes a drive assembly 4, which includes a drive unit 41 and a control unit 42.

The control unit 42 is electrically connected to the drive unit 41. The control unit 42 is used to control the working state of the drive unit 41.

[0114] With the above arrangement, the drive assembly 4, which consists of control unit 42 and drive unit 41, can control the forward and backward sliding of the movable tail compartment 2.

[0115] For example, the drive unit 41 may be an electric motor, a hydraulic cylinder, a pneumatic cylinder, etc. The control unit 42 may be independent or integrated into other control modules of the vehicle, such as the on-board computer.

[0116] Among some possible implementations, refer to Figure 10 As shown, the drive unit 41 and control unit 42 are located below the vehicle floor 52. The drive unit 41 can pass through the clearance channel of the vehicle floor 52 and be powered to the screw structure, driving the screw structure to rotate. In this embodiment, by arranging the drive unit 41 and control unit 42 below the vehicle floor 52, the space occupied by the drive unit 41 and control unit 42 in the vehicle's interior is reduced, and the operating noise of the drive unit 41 can be reduced to minimize interference with the user.

[0117] Among other possible implementations, see reference Figure 11As shown, the drive unit 41 and control unit 42 are located above the vehicle body floor 52. The drive unit 41 can be directly connected to the screw structure to drive the screw structure to rotate. In this embodiment, although the drive unit 41 and control unit 42 occupy the vehicle's internal space, it reduces the difficulty of connecting the drive unit 41 to the screw structure and avoids creating an obstacle passage on the vehicle body floor 52. The integrity of the vehicle body floor 52 is relatively high, and the sealing performance of the internal space is good.

[0118] In some possible implementations, the movable tailgate 2 can be set to a specific gear travel during the sliding process, and the sliding command can be obtained using the car's electronic screen, switch, smart key, mobile APP, voice, etc. For example, the movable tailgate 2 has an anti-pinch function during the sliding process.

[0119] On the other hand, combining Figures 1 to 4 As shown, this embodiment provides a vehicle, which includes: a tailgate device 100 and a body 200 of this application, wherein the tailgate device 100 is slidably connected to the rear end of the body 200.

[0120] The vehicle in this embodiment uses the tailgate device 100 of this application, and has all the beneficial technical effects of this application.

[0121] Combination Figure 12 and Figure 13 As shown, in some embodiments, the vehicle body 200 has a vehicle space 2001, and the vehicle space 2001 has a rear seat 6.

[0122] The rear seat 6 includes a seat cushion component 61 and a backrest component 62. The backrest component 62 includes a first backrest member 621 and a second backrest member 622, which are respectively movably arranged.

[0123] The rear seat 6 includes a first working mode and a second working mode; in the first working mode, the first backrest piece 621 and the second backrest piece 622 are spliced ​​and aligned from left to right and are vertically arranged at the rear end of the seat cushion piece 61; in the second working mode, the first backrest piece 621 and the second backrest piece 622 are separated from each other and respectively attached to the two side walls of the vehicle body space 2001.

[0124] Through the above arrangement, in order to further improve the spaciousness and comfort of the vehicle body space 2001 inside the vehicle body 200, the rear seats 6 of the vehicle adopt a movable design. The backrest component 62 of the rear seat 6 can be separated into a first backrest component 621 and a second backrest component 622 in the second working mode, and can be rotated and opened horizontally to both sides respectively, fitting against the two side walls of the vehicle body space 2001. Thus, the vehicle body space 2001 and the trunk space can be completely connected to form a larger flat space. This platform space can provide users with a more spacious and comfortable user experience.

[0125] Combination Figure 14 As shown, in some embodiments, the bottom ends of the first backrest member 621 and the second backrest member 622 near the side wall of the vehicle body space 2001 are respectively provided with backrest pivots 63. The first backrest member 621 and the second backrest member 622 are rotatably connected to the seat cushion member 61 by means of the backrest pivots 63. The first backrest member 621 and the second backrest member 622 can be rotated horizontally by means of the backrest pivots 63, thereby enabling the rear seat 6 to switch between a first working mode and a second working mode.

[0126] In some possible implementations, the horizontal rotation of the first backrest member 621 and the second backrest member 622 can be manual or electric. When the horizontal rotation of the first backrest member 621 and the second backrest member 622 is in electric mode, the horizontal rotation of the first backrest member 621 and the second backrest member 622 can be coordinated with the forward and backward sliding of the movable tailgate 2. For example, when the movable tailgate 2 is controlled to extend backward, the horizontal rotation of the first backrest member 621 and the second backrest member 622 opens, and the rear seat 6 switches to the second operating mode. When the movable tailgate 2 is controlled to retract forward, the horizontal rotation of the first backrest member 621 and the second backrest member 622 engages, and the rear seat 6 switches back to the first operating mode.

[0127] It should be noted that the mode switching for the 6 rear seats can also be performed independently.
