[0051] Unless otherwise defined, all technical and scientific terms used in the specification of the present application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the specification of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. The use of the term "and / or" in the specification of the present application includes any and all combinations of one or more of the associated listed items.

[0052] Please refer to Figure 1 and Figure 2 The present application provides a vehicle 1000, which comprises a vehicle body 200 and a tailgate device 100 (which can be referred to as tailgate device 100), a first opening 201 is formed at the tail of the vehicle body 200 in the length direction X of the vehicle 1000, and the tailgate device 100, also referred to as trunk door device, is rotatably connected at the tail position of the vehicle body 200 and used to open or close the first opening 201. When a user needs to take or put an article in the trunk, the tailgate device 100 can be opened to open the first opening 201, and when the taking or putting of the article is completed, the first opening 201 can be closed by the tailgate device 100.

[0053] In the embodiment, the vehicle 1000 is generally configured as a medium-large vehicle, for example, a large SUV, an MPV commercial vehicle, etc. For these vehicles, a common point is that the overall height of the vehicle is high, and accordingly the depth of the trunk in the vehicle height direction Z is also deep, so the size of the tailgate device 100 matched therewith is also large. At this time, for some limited space positions or small object taking scenarios, the large size tailgate device 100 cannot be opened, the opening angle is limited, or the opening is cumbersome, etc., resulting in poor overall user experience.

[0054] In view of the above technical problems, the prior art sets the tailgate device 100 as a combination of a child door and a parent door (i.e., a combination of a small door and a large door). When in some limited space positions or small object taking scenarios, the child door or small door can be selected to be opened, and when large objects need to be taken or large opening is required, the parent door or large door can be selected to be opened. With further changes or development of technology and demand, the user's demand for intelligent vehicle doors is increasing; at the same time, the vehicle tailgate needs to carry more structures, such as through-type tail lamps, various auxiliary cameras, tailgate controllers, etc., which causes some conflicts between the intelligent tailgate and the positions of these components, resulting in difficult arrangement. In view of this, the present application can effectively solve one or more of the above-mentioned problems through optimization of structure and layout.

[0055] Specifically, please refer to Figures 2 to 10The vehicle tail door device 100 comprises a mother door 10, a child door 20, a through type tail lamp 30 and a support rod group 40. The second opening 11 is formed on the mother door 10. The child door 20 can rotate relative to the mother door 10 to open and close the second opening 11. The through type tail lamp 30 is installed on the child door 20 and penetrates the child door 20 along the width direction Y of the vehicle 1000. The support rod group 40 is provided with at least one group, and at least one group of support rod groups 40 is located on one side of the mother door 10 in the width direction Y of the vehicle 1000. The support rod group 40 comprises a first electric support rod 41 and a second electric support rod 42. The first electric support rod 41 has a first movable end 411 and a first fixed end 412 arranged oppositely. The first movable end 411 is connected with the mother door 10, and the first fixed end 412 is used for rotatingly connecting the vehicle body 200. The second electric support rod 42 has a second movable end 421 and a second fixed end 422 arranged oppositely. The second movable end 421 is connected with the child door 20, and the second fixed end 422 is used for rotatingly connecting the vehicle body 200. In the height direction Z of the vehicle 1000, when the tail door device 100 is in a closed state, the first fixed end 412 is located above the first movable end 411, and the second fixed end 422 is located below the second movable end 421. It can be understood that the first electric support rod 41 and the second electric support rod 42 provided in the application realize the electric control of the mother door 10 and the child door 20, so that the starting of the vehicle tail door is more intelligent. At the same time, in the arrangement of the first electric support rod 41 and the second electric support rod 42, the first fixed end 412 is located above the first movable end 411, and the first electric support rod 41 is also called a positive support rod. The second fixed end 422 is located below the second movable end 421, and the second electric support rod 42 is also called a negative support rod. That is, the application adopts a combination form of positive and negative electric support rods for the mother door 10 and the child door 20. When the through type tail lamp 30 is arranged on the child door 20, the second fixed end 422 of the second electric support rod 42 is located below, and the second fixed end 422 sweeps a smaller envelope during movement, that is, the movement space required by the second fixed end 422 is smaller. In this way, even if the length of the second electric support rod 42 becomes longer, the mounting point of the second fixed end 422 can be moved downward in the height direction Z of the vehicle 1000, realizing the installation of the second electric support rod 42, and the second electric support rod 42 will not interfere with the through type tail lamp 30 during movement.

[0056] At the same time, in the application, the first fixed end 412 and the second fixed end 422 are arranged in an upper and lower manner in the height direction Z of the vehicle, that is, they are arranged in a staggered manner. In other words, the first fixed end 412 and the second fixed end 422 are not fixed at the same position of the vehicle body 200. In this way, the stress on the same position of the vehicle body 200 can be avoided, and the vehicle body 200 can be prevented from being concave or damaged.

[0057] Further, different from the "top and bottom door" or "double-leaf door" in the prior art, the "top and bottom door" is that two tail doors are opened by rotating up and down in the height direction Z of the vehicle, that is, one tail door is opened by rotating up and the other tail door is opened by rotating down. The "double-leaf door" is that two doors are opened by rotating left and right in the width direction Y of the vehicle. In the present application, the parent door 10 and the child door 20 are both rotated upwards in the height direction Z of the vehicle 1000 to open the first opening 201 and the second opening 11.

[0058] In an embodiment, please continue to refer to Figure 5 、 Figure 7 and Figure 8 , the child door 20 comprises a main body 22 and a rear window glass 23, the main body 22 is used to be rotatably connected to the tail of the vehicle 1000, that is, the tail of the vehicle body 200. The main body 22 is provided with a third opening 21, and the rear window glass 23 is installed on the main body 22 and covers the third opening 21; wherein the area of the third opening 21 is smaller than the area of the second opening 11. It should be explained that the second opening 11 can be used for users to take and place articles, and the third opening 21 is a rear view window, and the driver or passenger can observe the tail of the vehicle 1000 through the second opening 11 and then through the third opening 21, so as to improve the driving safety and experience.

[0059] Preferably, please refer to Figure 7 , the main body 22 is formed with a groove 221, the third opening 21 is located in the groove 221, the rear window glass 23 is fixed in the groove 221 by sealing glue, and the rear window glass 23 is basically flush with the groove of the groove 221 or the surface of the main body 22 in the length direction X of the vehicle 1000, so that the structure of the child door 20 is more integrated and compact.

[0060] Please refer to Figure 3 and Figure 11The sub-door 20 further comprises a spoiler 24 and an antenna controller 25. The spoiler 24 is installed on the main body 22, and the antenna controller 25 is installed at or near the middle of the main body 22. The spoiler 24 mainly functions to guide the airflow at the rear of the vehicle 1000, so as to make the vehicle 1000 run more stably. The antenna controller 25 mainly functions to transmit, receive and process various signals, so as to realize automatic driving, human-computer interaction and the like of the vehicle 1000. In the related art, the antenna controller 25 is generally installed on the spoiler 24 and located at both sides of the spoiler 24 in the vehicle width direction Y. However, in this embodiment, the tail door of the vehicle 1000 is a double-layer door, so the thickness of the vehicle 1000 in the length direction X is relatively large compared with a single-layer door, which causes the width of the spoiler 24 in the length direction X to be relatively large, so that the overall strength of the structure is poor. Moreover, when arranged at the position of the spoiler 24, the wire harness needs to pass through the spoiler 24 first, and then pass through the sub-door 20, so as to be connected with the tail door control (not shown in the figure). In this embodiment, the antenna controller 25 is arranged at or near the middle of the main body 22, that is, the antenna controller 25 is installed on the sub-door 20. In this way, on the one hand, the wire harness 50 can be directly connected with the controller on the tail door of the vehicle, so as to reduce the running direction of the wire harness and the plug connector, and on the other hand, after the antenna controller 25 is arranged at the middle of the main body 22, no space needs to be reserved at both sides of the vehicle in the width direction Y, so that the size of the spoiler 24 in the length direction X of the vehicle can be as small as possible, and on the basis of being small at both sides, the width of the spoiler 24 in the length direction X of the vehicle is also small, that is, the overall structural strength is improved.

[0061] In an embodiment, referring to Figures 11 to 12 The antenna controller 25 comprises a high-precision positioning antenna controller 251 and a satellite antenna controller 252. In the width direction Y of the vehicle 1000, the high-precision positioning antenna controller 251 and the satellite antenna controller 252 are arranged at both sides of the center axis L, so as to avoid mutual influence of signals between the antenna controllers 25. Here, the high-precision positioning antenna mainly provides high-precision positioning support for the vehicle 1000 in a complex environment, so as to improve the navigation progress, enhance the signal stability, and assist the auxiliary driving and intelligent control of the vehicle 1000. The satellite antenna controller mainly functions to collect weak signals transmitted by satellites, and remove as much noise and interference as possible, so as to improve the signal receiving capability of the vehicle in remote areas, ensure accurate positioning of the navigation system, and ensure the call rate and quality.

[0062] Of course, the antenna controller 25 can also comprise a navigation antenna controller, a communication antenna controller and the like, and the antenna controller 25 can be selected and arranged according to requirements.

[0063] Here, the high-precision positioning antenna controller is an existing technology. It refers to an integrated device that combines a "high-precision satellite signal receiving antenna" and a "positioning signal processing control module". Its core function is to receive carrier phase signals from satellite navigation systems (such as GPS, Beidou, GLONASS, Galileo) and combine them with algorithms such as RTK (real-time dynamic positioning technology) and PPP (precision point positioning technology) to achieve centimeter-level / sub-meter-level positioning of vehicles in three-dimensional space. The positioning data is then transmitted to the vehicle control system (such as the autonomous driving controller and navigation system) in real time, providing positioning support for functions such as autonomous driving, precise navigation, and lane-level assistance. Satellite antenna controllers are existing technology. They refer to integrated devices that combine a "satellite signal receiving antenna" and a "signal conditioning control module". Their core function is to receive radio frequency signals from global satellite navigation systems (GPS, BeiDou, GLONASS, Galileo, etc.) or satellite communication systems. After filtering, amplification, and anti-interference processing, the effective signals are transmitted to vehicle-related control systems (such as navigation modules, high-precision positioning antenna controllers, and vehicle networking terminals). At the same time, they have control functions such as signal status monitoring and power adjustment, providing stable signal support for vehicle positioning, navigation, and remote communication.

[0064] In one embodiment, such as Figures 13 to 15 As shown, a gap 253 is formed between the antenna controller 25 and the sub-door 20 in the height direction Z of the vehicle 1000; the vehicle tailgate device 100 also includes a wiring harness 50, which extends along the width direction Y of the vehicle and passes through the gap 253. That is, the wiring harness 50 is located relatively below the antenna controller 25. This arrangement serves two purposes: firstly, the gap 253 allows for a separation between the antenna controller 25 and the sub-door 20, thus preventing direct contact and relative movement that could cause abnormal noise; secondly, it makes full use of existing space to implement the wiring harness 50 layout, effectively saving other space, and also avoids interference from the magnetic field generated when the wiring harness 50 is energized on the signal of the antenna controller 25, making the transmission and reception of the antenna controller 25 signal more accurate.

[0065] Furthermore, such as Figure 14 As shown, the sub-gate 20 is provided with multiple support plates 26, and an accommodating space 261 is formed between two adjacent support plates 26. The antenna controller 25 is accommodated in the accommodating space 261 and installed on the support plate 26. It can be understood that the accommodating space 261 can initially position the antenna controller 25 so that the antenna controller 25 can be quickly assembled.

[0066] In the embodiment, the support plate 26 is arranged in an integral structure with the main body 22, which can effectively improve the structural strength of the support plate 26, thereby improving the reliability and stability of the installation of the antenna controller 25. Here, the support plate 26 and the main body 22 can be formed in an integral structure by integral casting or the like.

[0067] Further, please refer to Figure 13 and Figure 14 , the support plate 26 is provided with a mounting column 262, the mounting column 262 is provided with a threaded hole 263, the antenna controller 25 is provided with a mounting hole 254, the threaded hole 263 corresponds to the mounting hole 254; wherein one end of the threaded part is threaded through the mounting hole 254 and is screwed with the threaded hole 263. That is, the antenna controller 25 is fixed by the threaded part in a detachable manner, so that the installation and disassembly are more convenient. Here, the threaded part can be a screw or a bolt.

[0068] Preferably, please refer to Figure 14 , the support plate 26 is further provided with a limiting column 264, the antenna controller 25 is provided with a limiting hole 255, the limiting column 264 and the limiting hole 255 can be limited to cooperate. In this way, during installation, the antenna controller 25 can be first limited by the limiting column 264, and then the threaded part is threaded through the corresponding mounting hole 254 and connected with the threaded hole 263.

[0069] In the embodiment, the number of limiting columns 264 can be set to multiple, so that the antenna controller 25 is simultaneously limited by multiple limiting columns 264 to improve the stability of the limiting and installation.

[0072] In an embodiment, please refer to Figure 16 and Figure 17The intelligent electrical device 29 is installed on the parent door 10, and at least includes one of a 360-degree surround view camera 291, a streaming media camera 292, and an external microphone 293. Here, the 360-degree surround view camera 291 can capture the situation around the vehicle 1000. The streaming media camera 292 is mainly used to cooperate with the streaming media rearview mirror in the vehicle to provide the situation at the tail of the vehicle 1000 in real time; the external microphone 293 is mainly used to collect sound, and the user can realize voice control of the actions of the parent door 10 and the child door 20 through the external microphone 293 to realize human-vehicle interaction.

[0073] Please refer to Figure 4 The support rod group 40 is provided in two groups, and one group of the support rod group 40 is arranged on one side of the parent door 10 in the width direction Y of the vehicle 1000, and the other group of the support rod group 40 is arranged on the other side of the parent door 10. In this way, the left and right sides in the width direction Y of the vehicle can be supported by the child door and the parent door 10. This can improve the stability of the overall opening of the tail door.

[0074] Further, in each group of the support rod group 40, the first electric support rod 41 and the second electric support rod 42 are arranged in a cross manner; and in the width direction Y of the vehicle 1000, the second electric support rod 42 is located on the outer side of the first electric support rod 41, so that the parent door 10 is not interfered during opening and closing, and normal opening is ensured.

[0075] Please refer to Figure 4 and Figure 18 The vehicle tail door device 100 further includes a lock mechanism 60 and a cooperating part 61, one of the lock mechanism 60 and the cooperating part 61 is arranged on the parent door 10, and the other is arranged on the child door 20, and the lock mechanism 60 can be locked with the cooperating part 61, and the child door 20 is closed relative to the parent door 10.

[0076] In the present embodiment, the lock mechanism 60 is arranged on the child door 20, and the cooperating part 61 is arranged on the parent door 10.

[0077] Further, the lock mechanism 60 is configured as an electronic latch, when the child door 20 is opened relative to the parent door 10 by a preset angle p, the parent door 10 can be synchronized with the child door 20 through the electronic latch after being attracted, and then move synchronously, so that the tail door device 100 is more stable during overall opening and closing. In other words, when the child door 20 is opened relative to the parent door 10 by a preset angle p, the parent door 10 and the child door 20 form a whole, and then move synchronously.

[0078] Here, the electronic suction lock belongs to the conventional technology, which is not expanded here. The matching piece 61 is a lock catch or a lock hook, and of course, the structure of the matching piece 61 is not limited to the several types of examples, as long as it can cooperate with the electronic suction lock to realize the locking between the parent door 10 and the child door 20.

[0079] For example, when the parent door 10 is closed to the vehicle body 200, it can be considered that the parent door 10 is at 0° (i.e. 0 degree). When the parent door 10 is closed, the child door 20 is also closed to the parent door 10, and it can be considered that the child door 20 is at 0°. The parent door 10 can be opened to 80°, and the child door 20 can also be opened to 80°. Along the length direction X of the vehicle 1000, the rear end of the child door 20 at the maximum angle can be shorter than the rear end of the parent door 10 at the maximum angle by 300 mm or more, for example, 300 mm, 325 mm, etc.

[0080] In some use scenarios, such as when the preset angle p is 20 degrees, the parent door 10 is in a closed state, that is, the child door 20 is opened at an angle of 20 degrees relative to the parent door 10, at this time, if it is not convenient to take the article through the second opening 11, the parent door 10 can be selected to be opened, and the parent door 10 will be suctioned with the child door 20 at the 20-degree position to form a whole, and then continue to open or close. For example, when having a picnic by car, the child door 20 is opened for ventilation, at this time, the preset angle p can be a relatively large angle such as 60 degrees or 70 degrees, when it is found that the parent door 10 needs to be opened, the parent door 10 can be controlled to be opened and the angle of the parent door 10 is not affected by the child door 20, but when the parent door 10 is opened to the angle at which the child door 20 is currently located, the parent door 10 will be suctioned with the child door 20 at the current angle to form a whole, here, the parent door 10 can be opened by 1 degree, 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, etc. For example, when the parent door 10 is opened to 60 degrees or 70 degrees, it will be suctioned with the child door 20 to form a whole and then continue to move.

[0081] Please refer to Figure 6 and Figure 8 The vehicle tail door device 100 further comprises a hinge mechanism 70, the hinge mechanism 70 is used to be installed on the vehicle body 200, and the parent door 10 and the child door 20 are both hinged to the hinge mechanism 70.
