Description

Technical Field

[0001] This application relates to the field of automotive technology, specifically to a vehicle. Background Technology

[0002] A car tailgate is a door located at the rear of a vehicle, serving as a passageway for accessing the rear space. It is typically located at the rear of the vehicle, providing a convenient way to load and unload cargo and passengers. In current vehicle designs, the tailgate is connected to the body via hinges on both sides, and a drive mechanism is used to open and close it. Because the drive point of the drive mechanism is located on one side of the hinge, the center of gravity of the tailgate deviates significantly from the drive point, resulting in uneven force distribution during opening and closing, thus affecting the smoothness of the tailgate's operation.

[0003] Furthermore, the tailgate is kept closed by locking mechanisms located on both sides of the vehicle body. Because the drive point of the drive mechanism is located on the hinge on one side, the synchronicity of the locking mechanisms on both sides of the tailgate is poor, which can easily lead to asynchronous locking. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] This application provides a vehicle, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0029] To address the technical problem of uneven force distribution on both sides of the tailgate during opening and closing in existing technologies, one embodiment of this application provides a vehicle. The vehicle has a length direction and a width direction that are perpendicular to each other. The vehicle includes a body. The vehicle also includes a tailgate, which is rotatably connected to one side of the body in the length direction. The vehicle further includes a drive unit, which includes a telescopic drive rod, which is telescopically disposed on one of the body and the tailgate, and rotatably connected to the other of the body and the tailgate. The drive unit also includes a drive assembly, which is drively connected to the telescopic drive rod. The drive assembly is configured to drive the telescopic drive rod to extend or retract, causing the telescopic drive rod to rotate the tailgate relative to the body. In the width direction, the telescopic drive rod is positioned near the center of the tailgate. This will be described in detail below.

[0030] Please see Figure 1 , Figure 1 This is a structural schematic diagram of an embodiment of the vehicle described in this application.

[0031] In one embodiment, the vehicle has a length direction X and a width direction Y that are perpendicular to each other. The vehicle includes a body 10 and a tailgate 20, which is rotatably connected to one side of the body 10 in the length direction X. Optionally, the tailgate 20 and the body 10 can be rotatably connected by a mechanism such as a hinge 40 or a linkage.

[0032] For example, taking the rotatable connection between the tailgate 20 and the vehicle body 10 via hinges 40 as an example, there are two sets of hinges 40. These two sets of hinges 40 are distributed almost symmetrically on both sides of the center of mass of the tailgate 20 in the width direction Y. The two sets of hinges 40 cooperate to realize the rotatable connection between the tailgate 20 and the vehicle body 10, so that the tailgate 20 can rotate relatively stably and reliably relative to the vehicle body 10. In addition, in the width direction Y, lock bodies (not shown) are also almost symmetrically distributed on both sides of the center of mass of the tailgate 20. The tailgate 20 and the vehicle body 10 are engaged by the lock bodies on both sides to keep the tailgate 20 in the closed state. The tailgate 20 can be rotatably connected to the top or bottom of the vehicle body 10. This embodiment of the application uses the tailgate 20 being rotatably connected to the bottom of the vehicle body 10 as an example for illustration only, and does not limit the installation position of the tailgate 20.

[0033] Please refer to the following: Figure 2 , Figure 2 This is a schematic diagram of the structure of an embodiment of the driving device of this application.

[0034] In one embodiment, the vehicle further includes a drive unit 30 configured to drive the tailgate 20 to rotate relative to the vehicle body 10. Specifically, the drive unit 30 includes a telescopic drive rod 31 and a drive assembly 32. The telescopic drive rod 31 is telescopically disposed on one of the vehicle body 10 and the tailgate 20, and is rotatably connected to the other of the vehicle body 10 and the tailgate 20. The drive assembly 32 is drively connected to the telescopic drive rod 31 and is configured to drive the telescopic drive rod 31 to extend or retract, causing the telescopic drive rod 31 to rotate the tailgate 20 relative to the vehicle body 10, thereby causing the tailgate 20 to rotate between an open state and a closed state.

[0035] In the width direction Y, the telescopic drive rod 31 is positioned close to the center of the tailgate 20, that is, close to the center of mass of the tailgate 20. This helps to ensure that the tailgate 20 is subjected to uniform force on both sides in the width direction Y during rotation, avoiding the problem of eccentric force on both sides of the tailgate 20 as much as possible. This improves the smoothness of opening and closing the tailgate 20. Furthermore, the driving force on both sides of the tailgate 20 in the width direction Y is kept as consistent as possible, which also helps to ensure the synchronicity of the locking bodies on both sides of the tailgate 20, avoiding the problem of asynchronous locking bodies on both sides of the tailgate 20.

[0036] It should be noted that please refer to the following as well. Figure 3 and Figure 4 In the open state, the angle between the tailgate 20 and the length direction X is smaller than the angle between the tailgate 20 and the length direction X in the closed state. Optionally, in the open state, the tailgate 20 can be nearly parallel to the length direction X, that is, the angle between the tailgate 20 and the length direction X does not exceed 10°, such as... Figure 3 As shown; in the closed state, the tailgate 20 can be nearly perpendicular to the length direction X, that is, the angle between the tailgate 20 and the length direction X can be 80° to 90°, as shown. Figure 4 As shown. Furthermore, this embodiment is illustrated using the example of a telescopic drive rod 31 retractably mounted on the tailgate 20 and rotatably connected to the vehicle body 10, for illustrative purposes only and not as a limitation. When the tailgate 20 rotates from the open state to the closed state, the drive assembly 32 drives the telescopic drive rod 31 to retract; when the tailgate 20 rotates from the closed state to the open state, the drive assembly 32 drives the telescopic drive rod 31 to extend.

[0037] Please refer to the following: Figure 5 , Figure 5 This is a perspective structural diagram of an embodiment of the driving device of this application. Figure 5 The internal structure of the drive component 32 is shown in perspective.

[0038] In one embodiment, the drive assembly 32 includes a first drive member 321, a second drive member 322, and a power member 323. The first drive member 321 is connected to the telescopic drive rod 31, the second drive member 322 is threadedly connected to the first drive member 321, and the power member 323 is drively connected to the second drive member 322. The power member 323 is configured to drive the second drive member 322 to rotate, so that the second drive member 322 drives the telescopic drive rod 31 to extend or retract via the first drive member 321, thereby causing the telescopic drive rod 31 to drive the tailgate 20 to rotate relative to the vehicle body 10.

[0039] Furthermore, the outer wall of the first driving member 321 is provided with a first thread 3211, and the second driving member 322 is sleeved on the outer periphery of the first driving member 321, and the inner wall of the second driving member 322 is provided with a second thread (not shown). The first thread 3211 and the second thread are engaged to connect so that the rotation of the second driving member 322 drives the first driving member 321 to move. The power member 323 drives the second driving member 322 to rotate, and the second driving member 322, through the engagement of the first thread 3211 and the second thread, drives the first driving member 321 to move along the rotation axis of the second driving member 322, so that the first driving member 321 drives the telescopic driving rod 31 to extend or retract.

[0040] Of course, in other embodiments of this application, the first driving member 321 and the second driving member 322 are not limited to the first thread 3211 and the second thread engaging. For example, the first driving member 321 and the second driving member 322 can also engage through a linkage mechanism or the like, which is not limited here.

[0041] Furthermore, the power component 323 has a drive screw 3231, and the outer wall of the second drive component 322 is provided with a transmission tooth 3221. The drive screw 3231 meshes with the transmission tooth 3221 to drive the second drive component 322 to rotate. Under the drive of the power component 323, the drive screw 3231 rotates around its central axis, and the drive screw 3231 drives the second drive component 322 to rotate, so that the second drive component 322 drives the first drive component 321 to move through the engagement of the first thread 3211 and the second thread, thereby causing the first drive component 321 to drive the telescopic drive rod 31 to extend or retract.

[0042] It should be noted that the drive assembly 32 in this embodiment includes a first drive member 321, a second drive member 322 and a power member 323. The motion commutator that drives the telescopic drive rod 31 to extend or retract is eliminated, which simplifies the structure of the drive assembly 32 and reduces its cost. Furthermore, the overall volume of the drive assembly 32 is reduced, thus lowering the space requirements for its arrangement.

[0043] Of course, in other embodiments of this application, the drive component 32 is not limited to the above design. For example, the drive component 32 can drive the telescopic drive rod 31 to extend or retract by a cylinder, or the drive component 32 can drive the telescopic drive rod 31 to extend or retract by a linkage mechanism. This is not limited here.

[0044] In one embodiment, the drive unit 30 further includes a mounting base 34, which is disposed on either the vehicle body 10 or the tailgate 20, specifically on the tailgate 20. The drive assembly 32 is disposed on the mounting base 34. Specifically, the drive assembly 32 further includes a cover 33, which can be disposed on the mounting base 34. The cover 33 has an accommodating cavity 331 inside, in which the first drive member 321 and the second drive member 322 are accommodated.

[0045] like Figure 2As shown, the mounting base 34 has a clearance hole 341, through which the telescopic drive rod 31 extends and is rotatably connected to the other of the vehicle body 10 and the tailgate 20. During the rotation of the tailgate 20 relative to the vehicle body 10, the telescopic drive rod 31 can swing within the clearance hole 341. During the rotation of the tailgate 20 relative to the vehicle body 10, the telescopic drive rod 31 not only extends or retracts relative to the mounting base 34, but also swings in a direction perpendicular to the width direction Y. To enable the telescopic drive rod 31 to drive the tailgate 20 to rotate relative to the vehicle body 10, the clearance hole 341 extends at least in a direction perpendicular to the width direction Y, allowing the telescopic drive rod 31 to swing within the clearance hole 341 during the rotation of the tailgate 20 relative to the vehicle body 10. The clearance hole 341 can accommodate the motion envelope of the telescopic drive rod 31.

[0046] Furthermore, the drive device 30 also includes a brush 342, which is disposed on the wall of the clearance hole 341. The brush 342 can cover the gap between the telescopic drive rod 31 and the wall of the clearance hole 341, thereby preventing the internal structure of the drive assembly 32 from being exposed and blocking external impurities from entering the interior of the drive assembly 32 and affecting the working stability of the drive assembly 32. As the telescopic drive rod 31 swings in the clearance hole 341, the brush 342 can brush off foreign objects and impurities on the telescopic drive rod 31, preventing abnormal noise.

[0047] Optionally, the mounting bracket 34 can be fixed to the tailgate 20 using fasteners such as pre-embedded bolts. The drive assembly 32 can be fixed to the inner panel of the tailgate 20 using the mounting bracket 34, and the drive assembly 32 is located in the internal space of the tailgate 20, which is not limited here.

[0048] Please refer to the following: Figure 6 , Figure 6 This is a structural schematic diagram of an embodiment of the connecting bracket of this application.

[0049] In one embodiment, the drive unit 30 further includes a connecting bracket 35 disposed on the vehicle body 10. A telescopic drive rod 31 is disposed on the tailgate 20 and is rotatably connected to the connecting bracket 35. The drive assembly 32 is configured to drive the telescopic drive rod 31 to extend or retract relative to the tailgate 20.

[0050] In this embodiment, by setting a connecting bracket 35 on the vehicle body 10, the installation of the drive device 30 is stabilized, so that the drive assembly 32 can reliably and stably drive the vehicle body 10 through the telescopic drive rod 31, thereby ensuring that the tailgate 20 rotates relative to the vehicle body 10 reliably and stably.

[0051] Furthermore, one of the telescopic drive rod 31 and the connecting bracket 35 is provided with a ball head 361, and the other is provided with a connector 362. The ball head 361 and the connector 362 are rotatably connected, so that the telescopic drive rod 31 is rotatably connected to the connecting bracket 35. Figure 2 and Figure 6 An example is shown where the end of the telescopic drive rod 31 is provided with a connector 362 and the connecting bracket 35 is provided with a ball head 361. The ball head 361 is rotatably embedded in the spherical cavity of the connector 362, thereby realizing the rotational connection between the telescopic drive rod 31 and the connecting bracket 35.

[0052] It should be noted that, in the width direction Y, the connecting bracket 35 is positioned near the center of the tailgate 20, that is, near the center of mass of the tailgate 20. This makes it easier for the connecting bracket 35 to connect with the telescopic drive rod 31. Of course, in other embodiments of this application, the connecting bracket 35 can also be positioned at other locations on the vehicle body 10, and the connecting bracket 35 can be connected to the telescopic drive rod 31 via an adapter structure, which is not limited here.

[0053] Please refer to the following: Figure 7 , Figure 7 This is a structural schematic diagram of another embodiment of the vehicle described in this application.

[0054] In an alternative embodiment, this embodiment differs from the above embodiment in that the drive assembly 32 includes a power component 323 and a motion commutator 37. The power component 323 is connected to the telescopic drive rod 31 via the motion commutator 37. Specifically, the power component 323 may be an electric strut, etc. The motion commutator 37 is rotatably mounted on the tailgate 20. The linear motion of the drive portion of the power component 323 drives the motion commutator 37 to rotate, causing the motion commutator 37 to extend or retract the telescopic drive rod 31, thereby causing the telescopic drive rod 31 to open or close the tailgate 20.

[0055] The technical solutions provided in the embodiments of this application will be described below with reference to specific examples.

[0056] Example 1:

[0057] The vehicle includes a body 10 and a tailgate 20, the tailgate 20 being rotatably connected to one side of the body 10 in the length direction X. The vehicle also includes a drive unit 30, which includes a telescopic drive rod 31, telescopically mounted on the tailgate 20. The body 10 is provided with a connecting bracket 35. The end of the telescopic drive rod 31 is provided with a connector 362, and the connecting bracket 35 is provided with a ball head 361, the ball head 361 being rotatably embedded in the spherical cavity of the connector 362, thus achieving a rotatable connection between the telescopic drive rod 31 and the connecting bracket 35.

[0058] The drive unit 30 also includes a drive assembly 32, which includes a first drive member 321, a second drive member 322, and a power member 323. The first drive member 321 is connected to the telescopic drive rod 31, the second drive member 322 is threadedly connected to the first drive member 321, and the power member 323 is driven by the second drive member 322. The power member 323 is configured to drive the second drive member 322 to rotate, so that the second drive member 322 drives the telescopic drive rod 31 to extend or retract via the first drive member 321, thereby causing the telescopic drive rod 31 to drive the tailgate 20 to rotate relative to the vehicle body 10.

[0059] In the width direction Y, both the telescopic drive rod 31 and the connecting bracket 35 are positioned close to the center of the tailgate 20, with the telescopic drive rod 31 close to the center of gravity of the tailgate 20. This ensures that the tailgate 20 experiences uniform force on both sides in the width direction Y during rotation, minimizing eccentric force on both sides and improving the smoothness of opening and closing. Furthermore, maintaining consistent driving force on both sides of the tailgate 20 in the width direction Y also helps ensure the synchronous engagement of the locks on both sides of the tailgate 20, minimizing asynchronous engagement. The connecting bracket 35 secures the installation of the drive unit 30, enabling the drive assembly 32 to reliably and stably engage with the vehicle body 10 via the telescopic drive rod 31, thereby ensuring reliable and stable rotation of the tailgate 20 relative to the vehicle body 10.

[0060] Example 2:

[0061] The vehicle includes a body 10 and a tailgate 20, the tailgate 20 being rotatably connected to one side of the body 10 in the length direction X. The vehicle also includes a drive unit 30, which includes a telescopic drive rod 31, telescopically mounted on the tailgate 20. The body 10 is provided with a connecting bracket 35. The end of the telescopic drive rod 31 is provided with a connector 362, and the connecting bracket 35 is provided with a ball head 361, the ball head 361 being rotatably embedded in the spherical cavity of the connector 362, thus achieving a rotatable connection between the telescopic drive rod 31 and the connecting bracket 35.

[0062] The drive unit 30 also includes a drive assembly 32, which includes a power component 323 and a motion commutator. The power component 323 is connected to the telescopic drive rod 31 via the motion commutator. Specifically, the power component 323 may be an electric strut or the like. The motion commutator is rotatably mounted on the tailgate 20. The linear motion of the drive part of the power component 323 drives the motion commutator to rotate, causing the motion commutator to extend or retract the telescopic drive rod 31, thereby causing the telescopic drive rod 31 to open or close the tailgate 20.

[0063] In the width direction Y, both the telescopic drive rod 31 and the connecting bracket 35 are positioned close to the center of the tailgate 20, with the telescopic drive rod 31 close to the center of gravity of the tailgate 20. This ensures that the tailgate 20 experiences uniform force on both sides in the width direction Y during rotation, minimizing eccentric force on both sides and improving the smoothness of opening and closing. Furthermore, maintaining consistent driving force on both sides of the tailgate 20 in the width direction Y also helps ensure the synchronous engagement of the locks on both sides of the tailgate 20, minimizing asynchronous engagement. The connecting bracket 35 secures the installation of the drive unit 30, enabling the drive assembly 32 to reliably and stably engage with the vehicle body 10 via the telescopic drive rod 31, thereby ensuring reliable and stable rotation of the tailgate 20 relative to the vehicle body 10.

[0064] In summary, this application provides a vehicle. The vehicle's drive mechanism includes a telescopic drive rod and a drive assembly. The drive assembly is configured to drive the telescopic drive rod to extend or retract, causing the telescopic drive rod to rotate the tailgate relative to the vehicle body, thereby opening and closing the tailgate. In the width direction, the telescopic drive rod is positioned near the center of the tailgate, i.e., near the tailgate's center of gravity. This facilitates even force distribution on both sides of the tailgate in the width direction during rotation, improving the smoothness of opening and closing the tailgate and ensuring the synchronous engagement of the lock bodies on both sides of the tailgate in the width direction. Furthermore, the centrally located design of the drive mechanism in this application reduces matching problems between the tailgate and lock bodies caused by manufacturing tolerance fluctuations, lowers the difficulty of manufacturing and subsequent adjustments, and improves assembly efficiency.

[0065] The vehicle provided in this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
