[0029] This application provides a driving device and 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, in the following embodiments, 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.

[0030] To address the technical problem of how to automatically open and close a tailgate in the prior art, one embodiment of this application provides a drive device. The drive device includes a drive link, which is retractably mounted on one of the vehicle body and the tailgate, and is rotatably connected to the other of the vehicle body and the tailgate. The drive device also includes a transmission member, which is rotatably mounted on one of the vehicle body and the tailgate, and is drively connected to the drive link. The drive device further includes a gear transmission assembly, which is drively connected to the transmission member and configured to drive the transmission member to rotate, thereby causing the drive link to extend or retract, and thus causing the drive link to rotate the tailgate relative to the vehicle body. This will be described in detail below.

[0031] Please see Figure 1 , Figure 1 This is a structural schematic diagram of an embodiment of the vehicle described in this application.

[0032] 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.

[0033] 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.

[0034] The driving device according to the embodiments of this application will be described below.

[0035] Please refer to the following: Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of an embodiment of the driving device of this application. Figure 3 This is a schematic diagram of the structure of an embodiment of the driving device of this application from another perspective.

[0036] In one embodiment, the vehicle body 10 and the tailgate 20 are connected by a drive device 30. The drive device 30 drives the tailgate 20 to rotate relative to the vehicle body 10, thereby automatically opening and closing the tailgate 20. Specifically, the drive device 30 includes a drive link 31, which is retractably mounted on one of the vehicle body 10 and the tailgate 20, and is rotatably connected to the other of the two. The drive device 30 also includes a transmission member 32, which is rotatably mounted on one of the vehicle body 10 and the tailgate 20, and is driveably connected to the drive link 31. The drive device 30 further includes a gear transmission assembly 33, which is drively connected to the transmission member 32. The gear transmission assembly 33 is configured to drive the transmission member 32 to rotate, thereby causing the drive link 31 to extend or retract, so that the drive link 31 drives the tailgate 20 to rotate relative to the vehicle body 10.

[0037] In this embodiment, the gear transmission assembly 33 of the drive device 30 provides power to drive the transmission component 32 to rotate, thereby causing the drive linkage 31 to extend or retract, and the drive linkage 31 to rotate the tailgate 20 relative to the vehicle body 10. In other words, this embodiment provides an automated drive design for the tailgate 20, enabling the tailgate 20 to open and close automatically through the drive device 30. Furthermore, this embodiment uses the gear transmission assembly 33 instead of an electric strut drive method, which not only reduces cost but also simplifies the structure of the drive device 30. This embodiment provides an automated drive design for the tailgate 20, which has advantages such as low cost, simple structure, and compact structure, and is especially suitable for low-end models, maximizing the satisfaction of users' needs for the electric tailgate 20. In addition, the drive device 30 in this embodiment uses the design of the drive linkage 31 and the gear transmission assembly 33, avoiding the use of complex hydraulic or pneumatic systems and improving the durability and service life of the drive device 30.

[0038] It should be noted that please refer to the following as well. Figure 4 and Figure 5 The drive unit 30 drives the tailgate 20 to rotate between an open state and a closed state. 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°. Figure 4 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 5 As shown. Furthermore, this embodiment is illustrated using the example of a drive linkage 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 device 30 drives the drive linkage 31 to retract; when the tailgate 20 rotates from the closed state to the open state, the drive device 30 drives the drive linkage 31 to extend.

[0039] Please refer to the following: Figure 6 , Figure 6 This is a schematic diagram of the structure of one embodiment of the transmission component of this application.

[0040] In one embodiment, the transmission member 32 includes a transmission rod portion 321 and a transmission gear portion 322. One end of the transmission rod portion 321 is connected to the drive linkage 31, and the transmission gear portion 322 is connected to the other end of the transmission rod portion 321 and is connected to the gear transmission assembly 33. The gear transmission assembly 33 is configured to drive the transmission rod portion 321 to rotate via the transmission gear portion 322, thereby causing the drive linkage 31 to extend or retract, which in turn causes the drive linkage 31 to rotate the tailgate 20 relative to the vehicle body 10, thus enabling the tailgate 20 to open and close automatically.

[0041] For example, the transmission gear 322 adopts a sector gear design. The transmission rod 321 is strip-shaped, with one end connected to the side of the transmission gear 322 without teeth, and the end of the transmission rod 321 away from the transmission gear 322 being connected to the drive link 31. The gear transmission assembly 33 outputs torque to drive the transmission gear 322 to rotate, causing the transmission gear 322 to synchronously drive the transmission rod 321 to swing. Through the swinging of the transmission rod 321, the drive link 31 is extended or retracted.

[0042] In one embodiment, the gear transmission assembly 33 includes a power component 331 and a first linkage gear 332. The power component 331 is connected to the transmission gear 322 via the first linkage gear 332. The power component 331 is configured to drive the transmission gear 322 to rotate via the first linkage gear 332, thereby driving the transmission rod 321 to rotate. The transmission rod 321 drives the drive linkage 31 to extend or retract, thereby causing the drive linkage 31 to drive the tailgate 20 to rotate relative to the vehicle body 10, thus realizing the automatic opening and closing of the tailgate 20.

[0043] Optionally, the power component 331 can be a motor or other power element, which is not limited here. In this embodiment, the opening and closing actions of the tailgate 20 are realized by the forward and reverse rotation of the power component 331, which replaces the complex telescopic control of the electric strut, simplifies the drive control logic, reduces the difficulty of system integration, and facilitates maintenance and debugging.

[0044] Furthermore, the gear transmission assembly 33 also includes a second linkage gear 335, which is connected to the drive end of the power component 331 and also meshes with the first linkage gear 332. In this way, the output torque from the drive end of the power component 331 drives the second linkage gear 335 to rotate, causing the second linkage gear 335 to drive the first linkage gear 332 to rotate. The first linkage gear 332 then drives the transmission gear 322 to rotate, which in turn drives the transmission rod 321 to rotate. The transmission rod 321 then drives the drive connecting rod 31 to extend or retract, thereby causing the drive connecting rod 31 to rotate the tailgate 20 relative to the vehicle body 10, thus enabling the tailgate 20 to automatically open and close.

[0045] Furthermore, the first linkage gear 332 includes a first linkage tooth portion 333 and a second linkage tooth portion 334 stacked on top of each other. The first linkage tooth portion 333 is connected to the power component 331 for transmission, and the second linkage tooth portion 334 meshes with the transmission tooth portion 322 of the transmission component 32. Exemplarily, both the first linkage tooth portion 333 and the second linkage tooth portion 334 are complete gear structures, with the outer diameter of the first linkage tooth portion 333 being larger than the outer diameter of the second linkage tooth portion 334. In this embodiment, the torque output by the power component 331 is transmitted to the drive linkage 31 through the first linkage gear 332, the second linkage gear 335, and the transmission component 32, achieving smooth closing of the tailgate 20 and ensuring a certain opening and closing speed through a certain transmission ratio. Since the first linkage gear 332 is relatively large, it can be made of materials such as hard plastic, which helps to reduce the overall weight of the drive device 30 and lower costs. The transmission component 32 can be made of materials such as metal, and it has sufficient structural strength to ensure the stability and reliability of the transmission process.

[0046] In one embodiment, the drive device 30 further includes a first ball joint 341 and a first connector 342. The first ball joint 341 is disposed on one of the transmission rod portion 321 and the drive connecting rod 31 of the transmission member 32, and the first connector 342 is disposed on the other of the transmission rod portion 321 and the drive connecting rod 31. The first ball joint 341 and the first connector 342 are rotatably connected, so that the transmission member 32 is connected to the drive connecting rod 31 in a transmission manner. Furthermore, the first ball joint 341 and the first connector 342 also cooperate to allow the transmission member 32 and the drive connecting rod 31 to rotate relative to each other, so as to adapt to the relative rotation between the transmission member 32 and the drive connecting rod 31 during the process of the drive device 30 driving the tailgate 20 to rotate, ensuring that the tailgate 20 can be opened and closed. Figure 2 and Figure 6 An example is shown where a first ball head 341 is disposed on the transmission rod portion 321 of the transmission member 32, and a first connector 342 is disposed on the drive link 31.

[0047] In one embodiment, the drive device 30 further includes a second ball joint 343 and a second connector 344. The second ball joint 343 is disposed on one of the vehicle body 10 and the drive linkage 31, and the second connector 344 is disposed on the other of the vehicle body 10 and the drive linkage 31. The second ball joint 343 and the second connector 344 are rotatably connected, so that the drive linkage 31 is rotatably connected to the vehicle body 10 to adapt to the relative rotation between the drive linkage 31 and the vehicle body 10 during the process of the drive device 30 driving the tailgate 20 to rotate, thereby ensuring that the tailgate 20 can be opened and closed. Figure 2 and Figure 7 An example is shown where a second ball joint 343 is disposed on the vehicle body 10 and a second connector 344 is disposed on the drive linkage 31.

[0048] In one embodiment, the vehicle body 10 is provided with a connecting bracket 11, and a drive link 31 is provided on the tailgate 20, with the drive link 31 rotatably connected to the connecting bracket 11. The drive link 31 is configured to extend or retract relative to the tailgate 20. Through this method, this embodiment, by providing the connecting bracket 11 on the vehicle body 10, secures the installation of the drive device 30, enabling the gear transmission assembly 33 to reliably and stably engage with the vehicle body 10 via the drive link 31, thereby ensuring reliable and stable rotation of the tailgate 20 relative to the vehicle body 10. The aforementioned second ball joint 343 is provided on the connecting bracket 11. The connecting bracket 11 can be fixed to the vehicle body 10 by welding or riveting.

[0049] In one embodiment, the drive device 30 further includes a mounting member 35. A transmission member 32 is rotatably mounted to the mounting member 35 via a first shaft pin 361, a power member 331 is mounted to the mounting member 35, and a first linkage gear 332 is rotatably mounted to the mounting member 35 via a second shaft pin 362. Exemplarily, the first linkage tooth 333 of the first linkage gear 332 is located away from the mounting member 35 relative to the second linkage tooth 334. The transmission tooth 322 of the transmission member 32 is located on one side of the second linkage tooth 334, and the power member 331 is located on the side of the second linkage tooth 334 away from the transmission tooth 322. Exemplarily, the drive device 30 is mounted on the inner panel 21 of the tailgate 20; specifically, the mounting member 35 can be connected to the inner panel 21 by means of screws or other methods, so that the entire drive device 30 is fixed to the inner panel 21. Figure 8 As shown.

[0050] It should be noted that, as Figure 8 As shown, during the closing process of the tailgate 20, the power component 331 drives the first linkage gear 332 to rotate clockwise via the second linkage gear 335, causing the first linkage gear 332 to drive the transmission component 32 to rotate counterclockwise. This causes the transmission rod portion 321 of the transmission component 32 to drive the drive linkage 31 to retract, thereby driving the tailgate 20 to rotate relative to the vehicle body 10 and close. During the opening process of the tailgate 20, the power component 331 drives the first linkage gear 332 to rotate counterclockwise via the second linkage gear 335, causing the first linkage gear 332 to drive the transmission component 32 to rotate clockwise. This causes the transmission rod portion 321 of the transmission component 32 to drive the drive linkage 31 to extend, thereby driving the tailgate 20 to rotate relative to the vehicle body 10 and open.

[0051] In one embodiment, the drive link 31 is positioned near the center of the tailgate 20 in the width direction Y, i.e., near the center of mass of the tailgate 20. This facilitates the uniform force on both sides of the tailgate 20 in the width direction Y during rotation, minimizing the problem of eccentric force on both sides of the tailgate 20. This improves the smoothness of opening and closing the tailgate 20 and ensures that the driving force on both sides of the tailgate 20 is as consistent as possible. It also helps to ensure the synchronicity of the locking bodies on both sides of the tailgate 20, minimizing the problem of asynchronous locking bodies on both sides of the tailgate 20.

[0052] Correspondingly, in the width direction Y, the connecting bracket 11 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 11 to connect with the drive linkage 31. Of course, in other embodiments of this application, the connecting bracket 11 can also be positioned at other locations on the vehicle body 10, and the connecting bracket 11 can be connected to the drive linkage 31 through a transition structure, which is not limited here.

[0053] The technical solutions provided in the embodiments of this application will be described below with reference to specific examples.

[0054] Example 1:

[0055] The drive unit 30 is used to drive the tailgate 20 of the vehicle to rotate relative to the vehicle body 10, thereby automating the opening and closing of the tailgate 20. Specifically, the drive unit 30 includes a drive link 31, which is retractably mounted on one of the vehicle body 10 and the tailgate 20, and is rotatably connected to the other of the two. The drive unit 30 also includes a transmission member 32, which is rotatably mounted on one of the vehicle body 10 and the tailgate 20, and is driveably connected to the drive link 31. The drive unit 30 further includes a gear transmission assembly 33, which is drively connected to the transmission member 32. The gear transmission assembly 33 is configured to drive the transmission member 32 to rotate, thereby causing the drive link 31 to extend or retract, which in turn causes the tailgate 20 to rotate relative to the vehicle body 10.

[0056] The transmission component 32 includes a transmission rod portion 321 and a transmission gear portion 322. One end of the transmission rod portion 321 is connected to the drive connecting rod 31, and the transmission gear portion 322 is connected to the other end of the transmission rod portion 321 and is connected to the gear transmission assembly 33. The gear transmission assembly 33 includes a power component 331, a first linkage gear 332, and a second linkage gear 335. The power component 331 is connected to the transmission gear portion 322 via the first linkage gear 332, and the second linkage gear 335 is connected to the drive end of the power component 331 and also meshes with the first linkage gear 332. The drive end of the power component 331 outputs torque to drive the second linkage gear 335 to rotate, which in turn drives the first linkage gear 332 to rotate. The first linkage gear 332 drives the transmission gear 322 to rotate, which in turn drives the transmission rod 321 to rotate. The transmission rod 321 drives the drive link 31 to extend or retract, which in turn drives the tailgate 20 to rotate relative to the vehicle body 10, thereby enabling the tailgate 20 to open and close automatically.

[0057] like Figure 8 As shown, during the closing process of the tailgate 20, the power component 331 drives the first linkage gear 332 to rotate clockwise via the second linkage gear 335, causing the first linkage gear 332 to drive the transmission component 32 to rotate counterclockwise. This causes the transmission rod portion 321 of the transmission component 32 to drive the drive linkage 31 to retract, thereby driving the tailgate 20 to rotate relative to the vehicle body 10 and close. During the opening process of the tailgate 20, the power component 331 drives the first linkage gear 332 to rotate counterclockwise via the second linkage gear 335, causing the first linkage gear 332 to drive the transmission component 32 to rotate clockwise. This causes the transmission rod portion 321 of the transmission component 32 to drive the drive linkage 31 to extend, thereby driving the tailgate 20 to rotate relative to the vehicle body 10 and open.

[0058] Example 2:

[0059] 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 body 10 and the tailgate 20 are connected by a drive unit 30, which drives the tailgate 20 to rotate relative to the body 10, thereby automatically opening and closing the tailgate 20. The drive unit 30 includes a drive link 31, which is telescopically mounted on one of the vehicle body 10 and the tailgate 20, and is rotatably connected to the other of the two. The drive unit 30 also includes a transmission member 32, which is rotatably mounted on one of the vehicle body 10 and the tailgate 20, and is drively connected to the drive link 31. The drive unit 30 also includes a gear transmission assembly 33, which is connected to the transmission member 32. The gear transmission assembly 33 is configured to drive the transmission member 32 to rotate, so as to drive the drive linkage 31 to extend or retract through the transmission member 32, thereby causing the drive linkage 31 to drive the tailgate 20 to rotate relative to the vehicle body 10.

[0060] The transmission component 32 includes a transmission rod portion 321 and a transmission gear portion 322. One end of the transmission rod portion 321 is connected to the drive connecting rod 31, and the transmission gear portion 322 is connected to the other end of the transmission rod portion 321 and is connected to the gear transmission assembly 33. The gear transmission assembly 33 includes a power component 331, a first linkage gear 332, and a second linkage gear 335. The power component 331 is connected to the transmission gear portion 322 via the first linkage gear 332, and the second linkage gear 335 is connected to the drive end of the power component 331 and also meshes with the first linkage gear 332. The drive end of the power component 331 outputs torque to drive the second linkage gear 335 to rotate, which in turn drives the first linkage gear 332 to rotate. The first linkage gear 332 drives the transmission gear 322 to rotate, which in turn drives the transmission rod 321 to rotate. The transmission rod 321 drives the drive link 31 to extend or retract, which in turn drives the tailgate 20 to rotate relative to the vehicle body 10, thereby enabling the tailgate 20 to open and close automatically.

[0061] like Figure 8As shown, during the closing process of the tailgate 20, the power component 331 drives the first linkage gear 332 to rotate clockwise via the second linkage gear 335, causing the first linkage gear 332 to drive the transmission component 32 to rotate counterclockwise. This causes the transmission rod portion 321 of the transmission component 32 to drive the drive linkage 31 to retract, thereby driving the tailgate 20 to rotate relative to the vehicle body 10 and close. During the opening process of the tailgate 20, the power component 331 drives the first linkage gear 332 to rotate counterclockwise via the second linkage gear 335, causing the first linkage gear 332 to drive the transmission component 32 to rotate clockwise. This causes the transmission rod portion 321 of the transmission component 32 to drive the drive linkage 31 to extend, thereby driving the tailgate 20 to rotate relative to the vehicle body 10 and open.
