[0032] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0033] Reference below Figure 1-Figure 9 A vehicle 100 according to an embodiment of the present invention is described.

[0034] Combination Figure 1-Figure 9 As shown, the vehicle 100 according to the present utility model may mainly include: a vehicle body 10 and a back door assembly 20. The rear side of the vehicle body 10 is open, and the back door assembly 20 may include a back door component 21 and a glass component 22. The back door component 21 is arranged at the rear side of the vehicle body 10, and the lower end of the back door component 21 is rotatably connected to the vehicle body 10. The glass component 22 is arranged in the back door component 21 so as to be able to rise and fall. The glass component 22 selectively extends from the back door component 21 and seals the rear side of the vehicle body 10 together with the back door component 21.

[0035] Specifically, the rear side of the vehicle body 10 is open, and the back door assembly 20 is arranged at the rear side of the vehicle body 10, and the lower end of the back door member 21 in the back door assembly 20 is rotatably connected to the vehicle body 10, so that the back door assembly 20 can be opened downward or closed relative to the vehicle body 10, so that it is convenient for users to load and take out items. It can be understood that the back door assembly 20 is a door frameless structure, which is conducive to lightweight design.

[0036] Furthermore, by arranging the glass component 22 in the back door component 21 so as to be able to be raised and lowered, the glass component 22 can be extended from the back door component 21, so that the glass component 22 and the back door component 21 can seal the rear side of the vehicle body 10 together, or the glass component 22 can be at least partially extended into the back door component 21, and the rear side of the vehicle body 10 can be partially opened under the premise that the back door assembly 20 is rotated and closed relative to the vehicle body 10, or the glass component 22 can be completely extended into the back door component 21, and then the back door assembly 20 can be flipped up and opened relative to the vehicle body 10.

[0037] In this way, the tailgate assembly 20 of the vehicle 100 can have at least four working states, namely, closed state, slightly open state, half-open state and fully open state. The vehicle 100 can switch between the closed state, slightly open state, half-open state and fully open state to meet the user's usage needs in different scenarios.

[0038] Specifically, when the back door assembly 20 is in the closed state, Figure 1 As shown, the back door member 21 is flipped up relative to the vehicle body 10, and the back door member 21 seals a portion of the rear side of the vehicle body 10, and the glass member 22 is fully extended relative to the back door member 21, and the glass member 22 seals another portion of the rear side of the vehicle body 10, that is, the glass member 22 and the back door member 21 together seal the rear side of the vehicle body 10, which can prevent the items in the luggage box from falling or being stolen, and can improve the safety of the vehicle 100.

[0039] When the back door assembly 20 is in a slightly open state, Figure 3As shown, the back door member 21 is flipped up relative to the vehicle body 10, and the back door member 21 is sealed with a portion of the rear side of the vehicle body 10, and the glass member 22 is slightly lowered relative to the back door member 21, so that a vent can be formed between the glass member 22 and the vehicle body 10, which can facilitate ventilation between the space inside the vehicle and the space outside the vehicle, realize the ventilation function of the back door, thereby expanding the function of the back door assembly 20 and enhancing the user experience.

[0040] When the back door assembly 20 is in a half-open state, Figure 4 As shown, the back door member 21 is flipped up relative to the vehicle body 10, and the back door member 21 is sealed with a portion of the rear side of the vehicle body 10, and the glass member 22 is completely lowered into the back door member 21, so that a passage for taking and placing items can be formed between the glass member 22 and the vehicle body 10. The passage for taking and placing items can not only play a ventilation role, but also make it convenient for users to take and place small luggage items, avoiding the need for users to directly open the back door assembly 20, which can further enhance the user experience.

[0041] When the back door assembly 20 is in the fully open state, Figure 5-Figure 7 As shown, the glass member 22 is completely lowered into the back door member 21, and the back door member 21 is flipped down relative to the vehicle body 10. The back door assembly 20 completely opens the rear side of the vehicle body 10, which can facilitate users to take and put items, and can further enhance the user experience.

[0042] It should be noted that when the back door assembly 20 is in the fully open state, since the glass component 22 is completely dropped into the inside of the back door component 21, compared with the traditional lift-up or side-opening back door assembly, the movement space required for the back door assembly 20 to rotate relative to the vehicle body 10 to open or close can be reduced. This not only reduces the requirements for the operating space when the back door assembly 20 is opened and closed, but also prevents the back door assembly 20 from hitting surrounding people or objects when opening and closing.

[0043] Furthermore, when the back door assembly 20 is in a fully open state, the back door assembly 20 is located at the lower end of the vehicle body 10 and is arranged horizontally. The back door assembly 20 can also be used as a seat for the user, thereby further expanding the function of the back door assembly 20 and meeting the user's needs for use in scenarios such as outdoor camping and fishing that require a seat, thereby further improving the user's experience.

[0044] Therefore, by rotatably connecting the lower end of the back door component 21 to the vehicle body 10 and arranging the glass component 22 in the back door component 21 so that it can be raised and lowered, the back door assembly 20 of the vehicle 100 can have at least a closed state, a slightly open state, a half-open state and a fully open state, which not only reduces the movement space required for the back door assembly 20 to be opened or closed, but also expands the various functions of the back door assembly 20 to meet the user's usage needs in different scenarios, thereby improving the user's usage experience.

[0045] Combination Figure 7-Figure 9 As shown, a cavity 211 is provided in the back door component 21, and a glass lifter 212 is provided in the cavity 211. The glass component 22 is provided in the cavity 211 and is transmission-connected with the glass lifter 212. The glass lifter 212 selectively drives the glass component 22 so that the glass component 22 and the back door component 21 jointly seal the rear side of the vehicle body 10.

[0046] Specifically, the back door component 21 is configured as a cavity structure, a cavity 211 is provided in the back door component 21, and a glass lifter 212 is provided in the cavity 211, so that the lower end of the glass component 22 can be at least partially arranged in the cavity 211, so that the glass component 22 and the glass lifter 212 are transmission-connected, and the glass lifter 212 can selectively drive the glass component 22 to rise and fall relative to the back door component 21, so that the glass component 22 and the back door component 21 can jointly seal the rear side of the vehicle body 10, so that the back door assembly 20 is in a closed state, or the glass component 22 is at least partially retracted into the cavity 211, so that the back door assembly 20 is in a slightly open state, a half-open state or a fully open state, and then, under the premise of ensuring the normal operation of the back door assembly 100, the up and down lifting of the glass component 22 relative to the back door component 21 can be made more stable and reliable, and the back door assembly 20 can be made more intelligent and controllable.

[0047] There may be at least two glass lifters 212 , which are spaced apart in the lateral direction and are both in transmission cooperation with the glass member 22 , so that the glass member 22 can be lifted and lowered relative to the back door member 21 more stably and reliably.

[0048] Furthermore, in a specific embodiment of the present invention, the glass lifter 212 may be driven by a motor, which will not be described in detail herein.

[0049] Combination Figure 1-Figure 5 As shown, a sealing strip 11 is provided at the circumferential portion of the rear side of the vehicle body 10, and the glass member 22 selectively abuts against the sealing strip 11 for sealing. Specifically, by providing the sealing strip 11 at the circumferential portion of the rear side of the vehicle body 10, under the premise that the back door member 21 is sealed with the sealing strip 11, when the glass member 22 is fully raised, the circumference of the glass member 22 can also abut against the sealing strip 11 for sealing, thereby achieving the sealing performance of the back door assembly 20 with the vehicle body 10 in the closed state, preventing foreign matter such as water vapor from entering the vehicle through the gap between the back door assembly 20 and the vehicle body 10, and improving the reliability of the vehicle 100.

[0050] Furthermore, combined with Figure 2As shown, the vehicle body 10 is provided with a drainage groove, and a water guide edge 111 is provided on the inner side of the sealing strip 11, and the water guide edge 111 is extended downward to correspond to the drainage groove of the vehicle body 10. In this way, water that penetrates into the vehicle under special working conditions can also be guided to the drainage groove along the water guide edge 111 and flow out of the drainage groove, thereby preventing water from entering or even accumulating in the vehicle interior, further optimizing the structural design of the sealing strip 11 and even the vehicle 100, and improving the reliability of the vehicle 100.

[0051] Combination Figure 6-Figure 8 As shown, a hinge 12 is provided at the lower end of the rear side of the vehicle body 10 , and the back door member 21 is rotatably connected to the hinge 12 . There are multiple hinges 12 , and the multiple hinges 12 are spaced apart in the lateral direction of the vehicle body 10 .

[0052] Specifically, one end of the hinge 12 and the other end of the hinge 12 can rotate relative to the hinge 12 axis. By setting the hinge 12, one end of the hinge 12 is connected to the lower end of the rear side of the vehicle body 10, and the other end of the hinge 12 is connected to the lower end of the back door member 21. In this way, a rotatable connection between the back door member 21 and the vehicle body 10 can be achieved, which can make the rotatable connection between the back door member 21 and the vehicle body 10 easier to achieve.

[0053] Furthermore, a plurality of hinges 12 may be provided, and the plurality of hinges 12 may be spaced apart in the lateral direction of the vehicle body 10 , and the plurality of hinges 12 may be connected between the vehicle body 10 and the tailgate member 21 , thereby improving the connection strength and connection stability between the tailgate member 21 and the vehicle body 10 , and further improving the reliability of the vehicle 100 .

[0054] Combination Figure 5-Figure 7 As shown, a telescopic limiter 13 is provided at least at one lateral end of the rear side of the vehicle body 10 , one end of the telescopic limiter 13 is connected to the vehicle body 10 , and the other end is telescopically connected to the back door 21 to limit the maximum rotation angle of the back door 21 .

[0055] Specifically, by providing a telescopic limiter 13 at at least one end of the rear side of the vehicle body 10 in the lateral direction, and making one end of the telescopic limiter 13 connected to the vehicle body 10 and the other end telescopically connected to the back door member 21, when the back door member 21 is rotated relative to the vehicle body 10, the telescopic limiter 13 can be extended and retracted accordingly, without affecting the normal rotation of the back door member 21 relative to the vehicle body 10 and ensuring the back door assembly 20 switches between various working states, when the back door member 21 rotates downward to a limited angle relative to the vehicle body 10 and the back door assembly 20 switches to the closed state, the telescopic limiter 13 can be extended to the limit position, thereby limiting the continued rotation of the back door member 21 relative to the vehicle body 10, preventing the back door assembly 20 from being over-opened, and improving the stability and reliability of the back door assembly 20 in the closed state. The limited angle can be 90°.

[0056] Furthermore, there are two telescopic limit members 13, which are respectively arranged at the two lateral ends of the rear side of the vehicle body 10, and the two telescopic limit members 13 are respectively connected to the two lateral ends of the back door member 21, so that the two telescopic limit members 13 can limit the back door member 21 at the two lateral ends respectively, which can make the force on the back door member 21 more uniform and reasonable, thereby further improving the stability and reliability of the back door assembly 20 in the fully open state, and improving the reliability of the vehicle 100.

[0057] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the telescopic limiting member 13 is a limiting cable. When the back door member 21 rotates downward to a limited angle relative to the vehicle body 10 and the back door assembly 20 is switched to a closed state, the limiting cable is straightened to achieve a limiting effect on the back door member 21.

[0058] In other embodiments of the present invention, Figure 7 As shown, the telescopic limiter 13 is a telescopic support rod. When the back door member 21 rotates downward to a limited angle relative to the vehicle body 10 and the back door assembly 20 is switched to a closed state, the telescopic support rod is stretched to the longest position to limit the back door member 21. Furthermore, the telescopic support rod can be a damping support rod, so that the back door assembly 20 can be slowly raised and lowered, which can further improve the user experience.

[0059] It should be noted that an electric opening mechanism may be provided on the telescopic limit member 13, so that the back door assembly 20 may be automatically flipped down without manual operation by the user, thereby improving the automation and intelligence of the vehicle 100 and further enhancing the user experience.

[0060] Of course, the body domain controller can also be electrically connected to the tailgate assembly 20. The body domain controller can receive command data input from the air conditioner, smart key, and remote control device of the vehicle 100, control the operation of the tailgate assembly 20, and complete functions such as in-vehicle ventilation, remote door opening, and remote control, thereby further improving the automation and intelligence of the vehicle 100.

[0061] Combination Figure 5-Figure 8 As shown, a first locking portion 14 is provided at least at one lateral end of the rear side of the vehicle body 10 , and a second locking portion 213 is provided at least at one lateral end of the back door member 21 . The first locking portion 14 and the second locking portion 213 correspond to and selectively lock and cooperate with each other.

[0062] Specifically, a first locking portion 14 is provided at at least one lateral end of the rear side of the vehicle body 10, and correspondingly, a second locking portion 213 is provided at at least one lateral end of the back door member 21. When the back door member 21 is flipped up relative to the vehicle body 10 so that the back door member 21 seals a portion of the rear side of the vehicle body 10, the first locking portion 14 and the second locking portion 213 can be correspondingly locked and matched, thereby ensuring the locking between the back door assembly 20 and the vehicle body 10, preventing the back door assembly 20 from flipping down against the user's will, and keeping the back door assembly 20 in the locked position, thereby improving the reliability of the vehicle 100.

[0063] It is understandable that when the tailgate assembly 20 needs to be opened, it is only necessary to cancel the locking cooperation between the first locking portion 14 and the second locking portion 213, that is, cancel the locking between the tailgate member 21 and the vehicle body 10, so that the tailgate member 21 can be freely tilted downward relative to the vehicle body 10.

[0064] Furthermore, combined with Figure 5-Figure 8 As shown, one of the first locking portion 14 and the second locking portion 213 is a lock buckle, and the other is a lock groove, and the lock buckle and the lock groove are locked and matched. Specifically, one of the first locking portion 14 and the second locking portion 213 can be set as a lock buckle, and the other can be set as a lock groove, so that when the back door 21 is flipped up relative to the vehicle body 10, the lock buckle can directly extend into the lock groove to achieve the locking match between the lock buckle and the lock groove, that is, to achieve the locking match between the first locking portion 14 and the second locking portion 213, so that not only the speed and accuracy of the locking match between the first locking portion 14 and the second locking portion 213 can be improved, but also the stability and reliability between the first locking portion 14 and the second locking portion 213 can be improved.

[0065] Combination Figure 8 As shown, there are two first locking parts 14, which are respectively arranged at the two lateral ends of the rear side of the vehicle body 10, and there are two second locking parts 213, which are respectively arranged at the two lateral ends of the back door 21, and the two first locking parts 14 are locked and matched with the two second locking parts 213 in a one-to-one correspondence. In this way, when the back door 21 is turned up relative to the vehicle body 10 so that the back door 21 seals a part of the rear side of the vehicle body 10, two locking matches can be formed between the vehicle body 10 and the back door 21, and the two locking matches are respectively located at the two lateral ends of the vehicle body 10, so that the force between the back door 21 and the vehicle body 10 can be made more uniform and reasonable, thereby further improving the stability and reliability of the locking between the back door 21 and the vehicle body 10, and improving the reliability of the vehicle 100.

[0066] As described above, on the premise that the tailgate assembly 20 of the vehicle 100 has at least a closed state, a slightly open state, a half-open state and a fully open state, the stability of the tailgate assembly 20 of the vehicle 100 in each working state, as well as the reliability and intelligence of switching between the working states are improved, thereby further optimizing the structural design of the vehicle 100, improving the user experience, and enhancing the product competitiveness of the vehicle 100.
