Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The purpose of this utility model is to provide a liftable car rear cover mechanism and a car, so as to solve the problems existing in the prior art and improve loading flexibility.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 This embodiment provides a liftable car rear cover mechanism; please refer to [link / reference]. Figures 1-18 The system includes a cover assembly, an opening and closing drive mechanism, and a height adjustment mechanism. The cover assembly is positioned above the cargo compartment 1. The opening and closing drive mechanism is connected to the cover assembly and can drive the cover assembly to move relative to the cargo compartment 1 for opening and closing. The height adjustment mechanism is connected to both the cover assembly and the cargo compartment 1 and can drive the cover assembly to move vertically relative to the cargo compartment 1 to adjust the height of the cover assembly.

[0022] The cover assembly is opened and closed by setting an opening and closing drive mechanism, which can meet the opening and closing of the cargo box 1 and meet the loading and unloading requirements. The height of the cover assembly is adjusted by setting a height adjustment mechanism, so that the loading height inside the cargo box 1 can be adjusted, so that the loading height is not limited to the height of the cargo box 1 itself, which can meet the loading of large items and improve loading flexibility.

[0023] In the optional embodiment, more preferably, the cover assembly includes a fixed frame 14 and a movable cover. The opening and closing drive mechanism is disposed on the fixed frame 14, the height adjustment mechanism is connected to the fixed frame 14, the movable cover is disposed on the upper side of the fixed frame 14 and can move relative to the fixed frame 14, the opening and closing drive mechanism is connected to the movable cover and can drive the movable cover to move relative to the fixed frame 14 for opening and closing.

[0024] The movable cover, which is movable relative to the fixed frame 14, is moved under the opening and closing control of the opening and closing drive mechanism, thereby realizing the opening and closing of the cargo compartment 1.

[0025] In the optional scheme of this embodiment, more preferably, the movable cover includes a power flip cover 3 and a sliding flip cover 4. A positioning cover 2 is provided on one side above the fixed frame 14 and is fixedly mounted on the fixed frame 14. The power flip cover 3 is rotatably connected to the positioning cover 2. The sliding flip cover 4 is rotatably connected to the power flip cover 3 on one side and slidably connected to the fixed frame 14 on the other side. The opening and closing drive mechanism is driven to the power flip cover 3. The opening and closing drive mechanism can drive the power flip cover 3 to flip relative to the positioning cover 2 and can drive the sliding flip cover 4 to slide relative to the fixed frame 14.

[0026] The positioning cover 2 is fastened to the fixing frame 14 by the fifth fastening bolt 29. The folding hinge 6 is fastened to one end of the positioning cover 2 by the first fastening bolt 7. Another identical folding hinge 6 is fastened to one end of the power-operated flip cover 3 by the first fastening bolt 7. Simultaneously, the first rotating shaft 8 passes through the hinge holes of the two folding hinges 6, allowing the power-operated flip cover 3 to flip and fold relative to the positioning cover 2 along the center of the first rotating shaft 8. The same folding hinge 6 is fastened to the other end of the power-operated flip cover 3 by the first fastening bolt 7. Another identical folding hinge 6 is fastened to one end of the sliding flip cover 4 by the first fastening bolt 7. The first rotating shaft 8 also passes through the hinge holes of the two folding hinges 6. The power-operated flip cover 3 and the sliding flip cover 4 can be flipped and folded along the center of the first rotating shaft 8. The other end of the sliding flip cover 4 is provided with a first connecting seat 19. The first pulley 18 passes through the third rotating shaft 20 and enters the first connecting seat 19 at the other end of the sliding flip cover 4. The first pulley 18 can rotate along the center of the third rotating shaft 20. The fixed frame 14 is provided with a first slide rail 17. The sliding flip cover 4 slides with the first pulley 18 and the first slide rail 17. In this way, the opening and closing drive mechanism drives the power-operated flip cover 3 to flip relative to the positioning cover 2, which can drive the sliding flip cover 4 to slide relative to the fixed frame 14. Moreover, this way of cooperating between the power-operated flip cover 3 and the sliding flip cover 4 saves opening and closing space and ensures opening and closing stability.

[0027] In the optional scheme of this embodiment, more preferably, the opening and closing drive mechanism is set as a first telescopic mechanism 9, and the two ends of the first telescopic mechanism 9 are rotatably connected to the fixed frame 14 and the power flip cover 3 respectively; the first telescopic mechanism 9 can adjust its own length to drive the power flip cover 3 to flip relative to the positioning cover 2.

[0028] Specifically, the first telescopic mechanism 9 is configured as an electric cylinder. A second rotating shaft 13 is mounted on the fixed frame 14. One end of the electric cylinder is connected to the second rotating shaft 13 and can rotate relative to it. The second hinge seat 11 is connected and fastened to the power flip cover 3 via a second fastening bolt 12. The other end of the electric cylinder is connected to the second hinge seat 11 via a second rotating shaft 10 and can rotate relative to it. When the electric cylinder is energized, it telescopically extends and retracts, causing one end to hinge and rotate with the second rotating shaft 13, and the other end to hinge and rotate with the second rotating shaft 10. The extension and retraction of the push cylinder drives the power flip cover 3 to flip up and down. When the power flip cover 3 moves, it also drives the sliding flip cover 4 to fold. The gravity of the sliding flip cover 4 causes the first pulley 18 at the other end to always be in contact with the first slide rail 17 and slide relative to it when the sliding flip cover 4 moves, thereby completing the electric opening and closing action of the cover assembly. In the initial state, the electric push cylinder is in a certain tilted state, and the end of the electric push cylinder connected to the second hinge seat 11 is higher than the other end, so that the extension action of the electric push cylinder can drive the power flip cover 3 to flip up.

[0029] In the optional scheme of this embodiment, more preferably, the height adjustment mechanism is set as a lifting mechanism, and the upper and lower sides of the lifting mechanism are respectively connected to the cover assembly and the cargo box 1; the lifting mechanism can adjust its own vertical height to adjust the height of the cover assembly.

[0030] The vertical lifting mechanism can adjust the height of the cover assembly, thereby adjusting the loading height of the cargo box 1 and improving loading flexibility.

[0032] The fixed frame 14 is connected and fastened to the top plate 15 by the third fastening bolt 21 of the lowering mechanism fixing plate; the bottom plate 16 is connected and fastened to the cargo box 1 by the third fastening bolt 21; the scissor assembly is movably connected to the top plate 15 and the bottom plate 16; under the drive of the driving component, the scissor assembly extends and retracts vertically to adjust the height of the cover assembly.

[0033] In an optional embodiment, more preferably, the scissor lift assembly includes a first scissor lift arm 22, a second scissor lift arm 23, and a limiting plate 25 that are crossed and rotatably connected. The two vertically opposite rotating ends of the first scissor lift arm 22 and the second scissor lift arm 23 are rotatably connected to the bottom plate 16 and the top plate 15, respectively. The other two vertically opposite sliding ends of the first scissor lift arm 22 and the second scissor lift arm 23 are slidably connected to the top plate 15 and the bottom plate 16, respectively. The limiting plate 25 is fixedly connected to the first scissor lift arm 22 or the second scissor lift arm 23, and the limiting plate 25 can limit the relative rotation of the first scissor lift arm 22 and the second scissor lift arm 23. The driving component is drivenly connected to the rotating end of the first scissor lift arm 22 or the rotating end of the second scissor lift arm 23 so as to drive the first scissor lift arm 22 and the second scissor lift arm 23 to rotate relative to each other.

[0034] The driving component is a rotary motor 26, which is fastened to the first fixed seat 36 by an eighth fastening bolt 38. The first fixed seat 36 is fastened to the base plate 16 by a seventh fastening bolt 37. The motor shaft of the rotary motor 26 is fastened to the rotating end of the first scissor arm 22 by a ninth fastening bolt 39. The first scissor arm 22 can rotate with the center of the motor shaft of the rotary motor 26. One of the slide grooves 27 is fastened to the top plate 15 by a fourth fastening bolt 28. The two sides of the sliding end of the first scissor arm 22 are respectively connected to two second pulleys by a fourth shaft. The two second pulleys can rotate along the center of the second pulleys. At the same time, two second slide rails are provided on the slide groove 27. The two second pulleys can slide on the two second slide rails while rotating along the center of the fourth shaft. Similarly, the first... The second scissor arm 23 is connected to the first scissor arm 22 via a central pivot 24 and can rotate relative to the center of the central pivot 24. The third hinge seat is connected and fastened to the top plate 15 via a sixth fastening bolt. The rotating end of the second scissor arm 23 is connected to the third hinge seat via a fifth pivot 35 and can rotate along the center of the fifth pivot 35. The two sides of the sliding end of the second scissor arm 23 are respectively connected to two second pulleys via a fourth pivot. The two second pulleys can rotate along the center of the fourth pivot. At the same time, two second slide rails are provided on the slide groove 27. The two second pulleys can slide on the two second slide rails while rotating along the center of the fourth pivot. Moreover, a limit plate 25 is provided above the central pivot 24 of the first scissor arm 22 and the second scissor arm 23 to limit the raised position of the first scissor arm 22 and the second scissor arm 23. Specifically, the limiting plate 25 can be set on the first scissor arm 22 or the second scissor arm 23. When the first scissor arm 22 and the second scissor arm 23 rotate relative to each other and approach each other until the limiting plate 25 abuts against the first scissor arm 22 or the second scissor arm 23, the limit lifting position is reached.

[0035] When the rotary motor 26 is energized and rotates, it drives the first scissor arm 22 to rotate. At the same time, the second pulley at the sliding end of the first scissor arm 22 can slide on the second slide rail on the slide groove 27. The second scissor arm 23 rotates relative to the first scissor arm 22 of the lifting frame. Since the rotating end of the second scissor arm 23 is connected to the third hinge seat through the fifth rotating shaft 35 and can rotate relative to it, and the second pulley at the sliding end can slide on the second slide rail on the slide groove 27, when the rotary motor 26 drives the first scissor arm 22 to rotate, the centers of the first scissor arm 22 and the second scissor arm 23 rotate relative to each other, and the sliding ends of the first scissor arm 22 and the second scissor arm 23 begin to slide, thereby driving the top plate 15 to achieve the function of lifting and lowering. When the top plate 15 rises, the top plate 15 stops rising and reaches its highest position when the center of the first scissor arm 22 and the second scissor arm 23 contact the limiting plate 25; when the top plate 15 falls back down, the top plate 15 stops falling and reaches its lowest position when the bottom plate 16 contacts the sliding groove 27 on the top plate 15.

[0037] The telescopic sealing curtain 5 can be attached to the positioning cover 2, the power flip cover 3, and the sliding flip cover 4 with Velcro to achieve the effect of sealing and waterproofing the interior space of the cargo compartment 1. When the cover assembly needs to be flipped up and opened, the Velcro attached to the power flip cover 3 and the sliding flip cover 4 can be pulled off. The telescopic sealing curtain 5 can automatically extend and retract with the raising and lowering of the car rear cover, so that the interior space can be sealed and waterproofed in both the raised and lowered states of the cover assembly.

[0038] In this embodiment, two sets of opening and closing drive mechanisms and height adjustment mechanisms are symmetrically distributed on the left and right sides of the center of the cargo compartment 1, and they operate simultaneously to improve stability.

[0039] Example 2 This embodiment provides a liftable car rear cover mechanism; please refer to [link / reference].

The push rod 40 is fixed to the second fixed seat 41. The push end 43 of the push rod 40 is connected to the sliding end of the second scissor arm 23 and can rotate relative to it. The position of the rotary motor 26 in Embodiment 1 is replaced by the fifth rotating shaft 35.

[0041] The operation mode of this embodiment is the same as that of embodiment one, except that the rotational power of the rotary motor 26 in embodiment one is changed to the linear pushing force of the push rod 40. The push rod 40 is used to push the second scissor arm 23 to slide in the slide groove 27, so as to achieve the overall lifting and lowering effect of the scissor assembly, thereby realizing the lifting and lowering function of the cover assembly.
