Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle. Background Technology

[0002] Currently, the tailgates of vehicles on the market have a large turning radius when opening and closing, and they also excessively encroach on the space behind the vehicle when opened. Therefore, the external space required for opening and closing the tailgate is large, especially for SUVs. As the number of vehicles increases and parking spaces shrink, the space available for the tailgate to avoid collisions is gradually decreasing. When parking, cars not only need to leave enough space with the car behind or the wall, but also need to be careful not to scrape against the car behind or the wall when opening and closing the tailgate. This situation has brought inconvenience to the use of cars and its impact is becoming increasingly significant. Utility Model Content

[0003] The main purpose of this utility model is to propose a vehicle that solves the problem of the large amount of space occupied by the tailgate during and after opening.

[0004] To achieve the above objectives, the vehicle proposed in this utility model includes:

[0005] The vehicle body has a rear-side opening;

[0006] A tailgate, having an open state and a closed state, wherein when the tailgate is in the open state, it is located above the roof of the vehicle body; and when the tailgate is in the closed state, it closes the rear side opening.

[0007] The opening and closing structure includes a connecting rod and a hinged rotating arm. One end of the connecting rod is rotatably connected to the vehicle body, and the other end is rotatably connected to the bottom side of the tailgate. One end of the hinged rotating arm is slidably disposed on the tailgate, and the other end is rotatably connected to the top of the vehicle body.

[0008] In one embodiment, the opening and closing structure further includes a driving member, which is drivenly connected to the connecting rod to drive the connecting rod to rotate about the rotational position of the connecting rod and the vehicle body.

[0009] In one embodiment, the drive component is configured as a telescopic rod, one end of which is rotatably connected to the connecting rod and the other end of which is rotatably connected to the vehicle body.

[0010] In one embodiment, the opening and closing structure further includes a guide rail disposed on the tailgate and extending along the Z-axis direction, and the hinge rotating arm is slidably disposed on the guide rail.

[0011] In one embodiment, the hinge rotating arm includes a sliding body and a hinge portion. The sliding body is provided with a sliding cavity, and the hinge portion is rotatably connected to the top of the vehicle body. The sliding body slides with the guide rail through the sliding cavity, so that the sliding body can slide along the guide rail.

[0012] In one embodiment, the sliding body includes a first sidewall, a second sidewall, a third sidewall, a fourth sidewall, and a fifth sidewall connected by bending in sequence. The second sidewall and the fourth sidewall are disposed opposite to each other, and the first sidewall and the fifth sidewall are disposed opposite to the third sidewall to form the sliding cavity on the sliding body. The first sidewall and the fifth sidewall are spaced apart to form a clearance opening between the first sidewall and the fifth sidewall. The hinge portion is connected to the third sidewall. The guide rail includes a track body and a connecting section disposed on the track body. The connecting section passes through the clearance opening and is connected to the tailgate.

[0013] In one embodiment, a rolling element is provided between the guide rail and the hinge rotating arm.

[0014] In one embodiment, the rolling element is configured as a roller, which is disposed on the hinge rotating arm and used to abut against the guide rail.

[0015] In one embodiment, when the tailgate is in the open state, the tailgate is parallel to the roof of the vehicle body.

[0016] In one embodiment, a fixed arm is provided on the top of the vehicle body, the fixed arm is provided with a rotating shaft, and the hinged rotating arm is rotatably connected to the fixed arm through the rotating shaft; and / or

[0017] The tailgate is equipped with a fixed bracket, and the connecting rod is rotatably connected to the tailgate through the fixed bracket.

[0018] The technical solution of this utility model involves rotatably connecting one end of a connecting rod to the vehicle body and the other end to the bottom side of the tailgate. One end of a hinge arm is slidably mounted on the tailgate, while the other end is rotatably connected to the top of the vehicle body. When the tailgate is opened, the connecting rod rotates counterclockwise, causing the bottom side of the tailgate to move upwards away from the vehicle body. The top side of the tailgate and the hinge arm also rotate. Simultaneously, the tailgate slides upwards along the hinge arm, moving closer to the bottom side of the tailgate, thus causing the tailgate to flip over to the top of the vehicle roof. Compared to a tailgate that opens directly upwards, this solution reduces the space occupied by the tailgate during and after opening, thus minimizing the overall space occupied by the vehicle. This tailgate opening method also reduces the length of the tailgate protruding from the vehicle body after opening, facilitating forklift access to the rear of the vehicle for loading through the rear opening. Furthermore, this solution uses fewer components in its opening and closing mechanism, requiring less space and reducing the space occupied by the mechanism within the vehicle. Similarly, when the tailgate moves from the open state to the closed state, the linkage rotates clockwise, the bottom side of the tailgate moves downward and closer to the vehicle body, and at the same time, the hinge rotating arm and the tailgate rotate clockwise, and the tailgate slides downward along the hinge rotating arm, thereby closing the tailgate opening.

[0030] Currently, the tailgates of vehicles on the market have a large turning radius when opening and closing, and they also excessively encroach on the space behind the vehicle when opened. Therefore, the external space required for opening and closing the tailgate is large enough, especially for SUVs. As the number of vehicles increases and parking spaces shrink, the space available for the tailgate to avoid collisions is gradually decreasing. When parking, cars not only need to leave enough space with the car behind or the wall, but also need to be careful not to scrape against the car behind or the wall when opening and closing the tailgate. This situation has brought inconvenience to the use of cars and its impact is becoming increasingly significant.

[0031] To address the aforementioned problems, this utility model proposes a vehicle.

[0032] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the vehicle includes a body 100, a tailgate 200, and an opening and closing structure 300. The body 100 has a rear side opening 110. The tailgate 200 has an open state and a closed state. When the tailgate 200 is in the open state, it is located above the roof 120 of the body 100. When the tailgate 200 is in the closed state, it closes the rear side opening 110. The opening and closing structure 300 includes a connecting rod 310 and a hinge rotating arm 320. One end of the connecting rod 310 is rotatably connected to the body 100, and the other end is rotatably connected to the bottom side of the tailgate 200. One end of the hinge rotating arm 320 is slidably disposed on the tailgate 200, and the other end is rotatably connected to the top of the body 100.

[0033] The technical solution of this utility model involves rotatably connecting one end of the connecting rod 310 to the vehicle body 100 and the other end to the bottom side of the tailgate 200. One end of the hinge rotating arm 320 is slidably mounted on the tailgate 200, and the other end is rotatably connected to the top of the vehicle body 100. Thus, when the tailgate 200 is opened, the connecting rod 310 rotates counterclockwise, causing the bottom side of the tailgate 200 to move upwards away from the vehicle body 100. The top side of the tailgate 200 and the hinge rotating arm 320 also rotate. At this time, the tailgate 200 slides upwards along the hinge rotating arm 320. In other words, the hinged rotating arm 320 slides towards the bottom side of the tailgate 200, causing the tailgate 200 to flip over onto the roof 120 of the vehicle body 100. Compared to the tailgate 200 that opens directly upwards, this solution reduces the space occupied by the tailgate 200 during and after opening, thus reducing the overall space occupied by the tailgate 200. Because of this tailgate opening method, the length of the tailgate 200 protruding from the vehicle body 100 after opening is reduced, making it easier for forklifts to directly enter the rear of the vehicle for loading through the rear side opening 110. Furthermore, this solution uses fewer components for the opening and closing structure 300, requiring less space and thus reducing the space occupied by the opening and closing structure 300. Similarly, when the tailgate 200 moves from the open state to the closed state, the connecting rod 310 rotates clockwise, the bottom side of the tailgate 200 moves downward and towards the vehicle body 100, and at the same time, the hinge rotating arm 320 and the tailgate 200 rotate clockwise, and the tailgate 200 slides downward along the hinge rotating arm 320, thereby closing the tailgate 200 rear opening 110.

[0034] It should be noted that during the process of the tailgate 200 moving from the closed state to the open state, the hinge rotating arm 320 slides towards the bottom side of the tailgate 200. When the tailgate 200 is fully open, the hinge rotating arm 320 slides to a position close to the rotation position of the connecting rod 310 and the tailgate 200. During the process of the tailgate 200 moving from the open state to the closed state, the hinge rotating arm 320 slides towards the top side of the tailgate 200. When the tailgate 200 is fully closed, the hinge rotating arm 320 slides to a position close to the top side of the tailgate 200. In other words, the hinge rotating arm 320 is slidably mounted on the tailgate 200 along the Z-axis direction, that is, the hinge rotating arm 320 is slidably mounted on the tailgate 200 along the vertical direction.

[0035] The bottom side of the tailgate 200 refers to the side of the tailgate 200 closest to the ground when it is closed. The top side of the tailgate 200 refers to the side of the tailgate 200 furthest from the ground when it is closed. The Z-axis direction mentioned in this article refers to the vertical direction of the vehicle, and the Y-axis direction refers to the horizontal direction of the vehicle.

[0036] In this embodiment, the hinge rotating arm 320 is rotatably disposed on the top of the vehicle body 100 about the Y-axis, that is, the hinge rotating arm 320 is rotatably disposed on the top of the vehicle body 100 about the left-right axis.

[0037] Optionally, in this embodiment, the opening and closing structure 300 further includes a driving member, which is drivenly connected to the connecting rod 310 to drive the connecting rod 310 to rotate around the rotational position of the connecting rod 310 and the vehicle body 100. It can be understood that the driving member can drive the connecting rod 310 to rotate around the rotational position of the connecting rod 310 and the vehicle body 100, thereby driving the tailgate 200 to move towards an open or closed state. The driving member makes the opening or closing of the tailgate 200 more intelligent and effortless. This solution uses a driving member to drive the connecting rod 310 to open the tailgate 200, replacing the traditional method of manually supporting and rotating the tailgate 200 to open, which is especially user-friendly for children, the elderly, or people with limited strength. Of course, this solution is not limited to this; in other embodiments, a driving member may not be provided, and the user can drive the tailgate 200 to open or close by hand.

[0038] The drive unit has a self-locking mechanism to prevent accidental loosening or the tailgate 200 from falling, thus reducing safety hazards.

[0039] Furthermore, in this embodiment, the drive unit is controlled via a control button. Of course, in other embodiments, the drive unit can also be controlled via a car key remote or a foot-activated sensor, thereby easily opening / closing the tailgate 200.

[0040] Furthermore, in this embodiment, the driving component is configured as a telescopic rod 330. One end of the telescopic rod 330 is rotatably connected to the connecting rod 310, and the other end is rotatably connected to the vehicle body 100. Specifically, when the telescopic rod 330 extends, it pushes the connecting rod 310 to rotate counterclockwise around the rotational position of the connecting rod 310 and the vehicle body 100, thereby pushing the bottom side of the tailgate 200 to move upward away from the vehicle body 100. The top side of the tailgate 200 and the hinge rotating arm 320 also rotate. At this time, the tailgate 200 slides upward along the hinge rotating arm 320, thereby causing the tailgate 200 to flip over to the top of the roof 120 of the vehicle body 100. When the telescopic rod 330 is shortened, it pulls the connecting rod 310 to rotate clockwise around the rotational position of the connecting rod 310 and the vehicle body 100. This pulls the bottom side of the tailgate 200 downwards and towards the vehicle body 100. Simultaneously, the hinge rotating arm 320 and the tailgate 200 rotate clockwise, and the tailgate 200 slides downwards along the hinge rotating arm 320, thereby closing the tailgate opening 110. This design uses the telescopic rod 330 and the connecting rod 310 to jointly drive the tailgate 200. This allows the telescopic rod 330 to utilize a relatively small linear displacement, which can be amplified and converted into a relatively large rotation angle at the hinge point of the tailgate 200. Therefore, with the same stroke, the telescopic rod 330 can be made shorter, and the opening and closing structure 300 can be more compact.

[0041] In this embodiment, the telescopic rod 330 is configured as an electric strut. This is because the electric strut has a built-in sensor that can detect obstacles (such as hands or luggage) during the closing process, automatically stop and rebound to avoid the risk of pinching. Secondly, the electric strut has a self-locking mechanism to prevent accidental loosening or the tailgate 200 from falling, reducing safety hazards. Moreover, the electric strut is compact, reducing external protrusions, improving the appearance and freeing up interior space at the rear of the vehicle. The electric strut can be linked with the vehicle system, such as automatically turning on lights or activating windshield wipers when the door is opened. Of course, this solution is not limited to this. In the second embodiment, the telescopic rod 330 can also be configured as a hydraulic strut. Of course, this solution is not limited to this. In the third embodiment, the telescopic rod 330 can also be configured as a gas strut.

[0042] Furthermore, in this embodiment, one end of the telescopic rod 330 is rotatably connected to the connecting rod 310 via a ball-head bolt, and the other end of the telescopic rod 330 is rotatably connected to the vehicle body 100 via a ball-head bolt. This improves the smoothness of the rotation of the telescopic rod 330. However, this solution is not limited to this. In the second embodiment, one end of the telescopic rod 330 is rotatably connected to the connecting rod 310 via a ball-head bolt, while the other end of the telescopic rod 330 is directly rotatably connected to the vehicle body 100 without being rotatably connected via a ball-head bolt. Of course, this solution is not limited to this. In the third embodiment, one end of the telescopic rod 330 is directly rotatably connected to the connecting rod 310 without being rotatably connected via a ball-head bolt, while the other end of the telescopic rod 330 is rotatably connected to the vehicle body 100 via a ball-head bolt.

[0043] Optionally, in this embodiment, the opening and closing structure 300 further includes a guide rail 340 disposed on the tailgate 200 and extending along the Z-axis direction, and the hinge rotating arm 320 is slidably disposed on the guide rail 340, which facilitates the assembly of the hinge rotating arm 320 and the sliding structure of the tailgate 200. Of course, this solution is not limited to this. In other embodiments, a track groove extending along the Z-axis direction can also be provided on the tailgate 200, and one end of the hinge rotating arm 320 can be slidably recessed into the track groove, which can make the structure of the tailgate 200 more compact.

[0044] Reference Figure 3 and Figure 4 Furthermore, the hinge rotating arm 320 includes a sliding body 321 and a hinge part 322. The sliding body 321 is provided with a sliding cavity, and the hinge part 322 is rotatably connected to the top of the vehicle body 100. The sliding body 321 slides with the guide rail 340 through the sliding cavity, so that the sliding body 321 can slide along the guide rail 340. Such a sliding structure is simple and easy to process and manufacture.

[0045] In this embodiment, the sliding body 321 includes a first sidewall 321a, a second sidewall 321b, a third sidewall 321c, a fourth sidewall 321d, and a fifth sidewall 321e connected by bending in sequence. The second sidewall 321b and the fourth sidewall 321d are arranged opposite to each other, and the first sidewall 321a and the fifth sidewall 321e are respectively arranged opposite to the third sidewall 321c to form a sliding cavity on the sliding body 321. The first sidewall 321a and the fifth sidewall 321e are spaced apart to form a clearance opening between the first sidewall 321a and the fifth sidewall 321e. The hinge part 322 is connected to the third sidewall 321c. The guide rail 340 includes a track body 341 and a connecting section 342 disposed on the track body 341. The connecting section 342 passes through the clearance opening and is connected to the tailgate 200. This can increase the connection area between the guide rail 340 and the tailgate 200, thereby improving the connection stability between the guide rail 340 and the tailgate 200. Of course, this solution is not limited to this. In other embodiments, a sliding ring can be provided on the sliding body 321, a sliding cavity can be formed in the sliding ring, a guide rail 340 can slide through the sliding cavity, and both ends of the guide rail 340 can be connected to the tailgate 200.

[0046] Optionally, a rolling element 350 is provided between the guide rail 340 and the hinge rotating arm 320, which can reduce the friction between the guide rail 340 and the hinge rotating arm 320, thereby making the sliding of the guide rail 340 smoother.

[0047] Furthermore, the rolling element 350 is configured as a roller, which is mounted on the hinge rotating arm 320 and abuts against the guide rail 340. This further reduces the friction between the guide rail 340 and the hinge rotating arm 320, thereby making the sliding of the guide rail 340 smoother. Of course, this solution is not limited to this; in other embodiments, the rolling element 350 can also be configured as a drum.

[0048] Reference Figure 2 Optionally, when the tailgate 200 is in the open state, the tailgate 200 is parallel to the roof 120 of the vehicle body 100. This can reduce the space occupied by the vehicle above when the tailgate is open, and at the same time improve the aesthetics of the vehicle after the tailgate 200 is opened.

[0049] It should be noted that the parallelism mentioned in this plan is not absolute parallelism, but can also refer to a slight inclination, with the degree of inclination between ±2°.

[0050] In one embodiment, a fixed arm 130 is provided on the top of the vehicle body 100, the fixed arm 130 is provided with a rotating shaft 140, and a hinge rotating arm 320 is rotatably connected to the fixed arm 130 through the rotating shaft 140; and / or the tailgate 200 is provided with a fixed bracket 210, and a connecting rod 310 is rotatably connected to the tailgate 200 through the fixed bracket 210.

[0051] In one embodiment, a fixed arm 130 is provided on the top of the vehicle body 100, and the fixed arm 130 is provided with a rotating shaft 140. A hinge rotating arm 320 is rotatably connected to the fixed arm 130 through the rotating shaft 140. The fixed arm 130 facilitates the rotational connection operation between the hinge rotating arm 320 and the vehicle body 100. The rotating shaft 140 extends in the Y-axis direction. Of course, this solution is not limited to this. In other embodiments, a rotating recess can also be provided on the top of the vehicle body 100, and a rotating shaft extending in the Y-axis direction can be provided in the rotating recess. The hinge rotating arm 320 rotates in the rotating recess through the rotating shaft.

[0052] Optionally, in one embodiment, the tailgate 200 is provided with a fixed bracket 210, and the connecting rod 310 is rotatably connected to the tailgate 200 through the fixed bracket 210, which facilitates the rotatable connection operation between the connecting rod 310 and the tailgate 200. Of course, this solution is not limited to this. In other embodiments, a mounting recess can be provided on the tailgate 200, and a rotating shaft can be provided in the mounting recess, through which the connecting rod 310 is rotatably connected to the tailgate 200.
