Description

Technical Field

[0001] This utility model belongs to the field of vehicle tailgate technology, and more specifically, it relates to a tailgate assembly and a vehicle. Background Technology

[0002] The tailgate is the structure on a car used to cover the trunk, also known as the trunk lid. Most common tailgates are one-piece flip-up tailgates, consisting of a top cover extending in the front-to-back direction and a back panel connected to the rear of the top cover. The back panel extends below the top cover and abuts against the rear panel. Flip-up tailgates have a simple structure; they flip upwards to open, allowing items to be taken out and put into the trunk. However, after the flip-up tailgate is opened, the top cover rotates to be parallel to the vertical direction, and the back panel extends backward. For larger or longer items, even when the flip-up tailgate is fully open, it is not easy to put them into the trunk.

[0003] Of course, some models feature a split-opening tailgate, either side-to-side or top-to-bottom, to increase the opening size of the trunk and facilitate loading and unloading. However, side-to-side tailgates have more specific requirements for the vehicle model, while top-to-bottom tailgates typically rotate upwards when the top tailgate is opened, reaching or slightly exceeding the roofline. At this point, items need to be placed horizontally from the rear of the vehicle, which can be inconvenient for some oddly shaped items. Furthermore, if the tailgate's tilt angle is too large, it will occupy too much overhead space, making it difficult to fully open in confined areas. Utility Model Content

[0004] The purpose of this utility model is to provide a tailgate assembly and vehicle, which aims to solve the problem that when using a split tailgate in the prior art, the maximum opening of the upper tailgate can only be slightly higher than or flush with the roof, resulting in limited space above the luggage compartment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] Firstly, a tailgate assembly is provided, comprising:

[0007] The upper tailgate unit includes an upper tailgate body, a traction assembly connected to the front of the upper tailgate body, and a support assembly connected to the rear of the upper tailgate body. The support assembly is used to lift the rear of the upper tailgate body upwards, and the traction assembly is used to pull the upper tailgate body forward to above the roof. It also includes a traction drive assembly connected to the traction assembly and the support assembly respectively.

[0008] The lower tailgate unit includes a lower tailgate body rotatably connected to the vehicle body and a telescopic drive assembly rotatably connected to the lower tailgate body, the telescopic drive assembly also being rotatably connected to the vehicle body.

[0009] In conjunction with the first aspect, in one possible implementation, the lower tailgate unit further includes a locking component connected to the lower tailgate body, the locking component comprising:

[0010] The mounting bracket includes a fixing part connected to the lower tailgate body and a mounting part connected at an angle to the fixing part, the mounting part extending towards the front side of the lower tailgate body; and

[0011] A lock, connected to the mounting part, is used to lock with a latch on the vehicle body.

[0012] In conjunction with the first aspect, in one possible implementation, the mounting part includes a mounting plate connected to the fixing part and a mounting hook connected to the mounting plate, the mounting hook being inserted into the mounting hole of the lock.

[0013] In conjunction with the first aspect, in one possible implementation, the lower tailgate body includes a lower tailgate outer panel, a lower tailgate reinforcing plate, and a lower tailgate inner panel arranged sequentially from the outside to the inside. The lower tailgate inner panel has a clearance hole, the fixing part is connected to the lower tailgate reinforcing plate, and the mounting part extends through the clearance hole toward the front side of the lower tailgate inner panel.

[0014] In conjunction with the first aspect, in one possible implementation, the traction drive component includes:

[0015] A front-drive mechanism includes a front-drive module disposed on the vehicle body and a front-drive flexible shaft connected to the front-drive module, the rear portion of the front-drive flexible shaft being connected to the traction assembly; and

[0016] The rear drive mechanism includes a rear drive module disposed on the vehicle body and a rear flexible shaft connected to the rear drive module, the rear part of the rear flexible shaft being connected to the support assembly.

[0017] In conjunction with the first aspect, in one possible implementation, both the front flexible shaft and the rear flexible shaft are provided with a drive rack along their own axial direction, and both the front drive module and the rear drive module include a driver and a transmission gear connected to the driver, the transmission gear meshing with the drive rack.

[0018] In conjunction with the first aspect, in one possible implementation, the traction component includes:

[0019] The traction rail is installed on the vehicle body in the front-rear direction and is located on the front side of the upper tailgate body;

[0020] A sliding member is slidably connected to the traction rail in a front-to-back direction and connected to the traction drive assembly, the traction drive assembly being used to drive the sliding member to slide along the traction rail; and

[0021] A hinge is rotatably or slidably connected to the sliding member and rotatably connected to the front of the upper tailgate body. The hinge is used to raise or lower the upper tailgate body.

[0022] In conjunction with the first aspect, in one possible implementation, the sliding member has a sliding groove, and the rear part of the sliding groove has a lifting area, the tail end of the lifting area is inclined upward, and the hinge member has a sliding end that is slidably inserted into the sliding groove and a hinge end that is rotatably connected to the upper back door body.

[0023] In conjunction with the first aspect, in one possible implementation, the supporting component includes:

[0024] A guide mechanism is provided on the upper rear door body along the front-to-back direction; and

[0025] The support mechanism includes a connector that is slidably connected to the guide mechanism in the front-rear direction and a support that is rotatably connected to the connector, the support being rotatably connected to the vehicle body.

[0026] The advantages of this utility model's tailgate assembly are as follows: Compared with the prior art, both the upper and lower tailgate units of this utility model's tailgate assembly can be opened independently. When the upper tailgate unit is opened, the support assembly first raises the rear of the upper tailgate body upwards to be level with or higher than the front. The traction drive assembly drives the traction component forward, thereby moving the upper tailgate body forward. While the upper tailgate body moves forward, the support assembly remains stationary. When the front of the upper tailgate body moves above the roof, the support component corresponds to the rear of the upper tailgate body. The traction drive assembly no longer drives the traction component but instead drives the support component to rotate forward, controlling the upper tailgate body to continue moving forward until the upper tailgate body is completely above the roof. When the lower tailgate body is opened, the telescopic drive assembly extends and rotates relative to the vehicle body and the lower tailgate body, flipping the lower tailgate body downwards to open. This utility model allows for the independent opening of both the upper and lower tailgate bodies, enabling flexible opening according to actual conditions. Furthermore, when the tailgate is open, not only can the support assembly flip the tailgate upwards, but the towing assembly can also move the tailgate to the roof, completely opening the top of the trunk and increasing the space for loading and unloading items. The tailgate in this invention does not require an excessively large upward flip, thus requiring less space above the vehicle and making it easier to load and unload larger items.

[0027] Secondly, this utility model embodiment also provides a vehicle including any of the above-described tailgate assemblies.

[0028] The beneficial effects of the vehicle provided by this utility model are as follows: compared with the prior art, it adopts the above-mentioned tailgate assembly, which has similar technical effects to the above-mentioned tailgate assembly, and will not be described in detail here.

[0040] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0041] In the claims, description, and accompanying drawings of this utility model, unless otherwise expressly defined, the terms "first," "second," or "third," etc., are used to distinguish different objects, not to describe a specific order. The directional terms "upper" and "lower" in the claims, description, and accompanying drawings of this utility model correspond to the vertical direction of the vehicle body; the terms "left" and "right" correspond to the horizontal direction of the vehicle body; the terms "front" and "rear" correspond to the front-rear direction of the vehicle body; and the term "inner side" refers to the side of the vehicle body adjacent to the passenger compartment in the horizontal direction, and vice versa. Unless otherwise stated, other directional terms, such as "vertical," "clockwise," and "counterclockwise," indicate the direction or positional relationship based on the direction and positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, not to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific protection scope of this utility model. In the claims, description, and accompanying drawings of this utility model, unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" should be interpreted broadly to refer to any connection method in which there is no displacement or relative rotation relationship between the two parties. This includes non-removable fixed connections, detachable fixed connections, integral connections, and fixed connections via other devices or elements. In the claims, description, and accompanying drawings of this utility model, the terms "comprising," "having," and variations thereof are intended to mean "including but not limited to."

[0042] Please refer to the following: Figures 1 to 9The present invention will now describe the tailgate assembly and the vehicle provided. The tailgate assembly includes an upper tailgate unit and a lower tailgate unit. The upper tailgate unit includes an upper tailgate body 1, a traction component 3 connected to the front of the upper tailgate body 1, and a support component 2 connected to the rear of the upper tailgate body 1. The support component 2 is used to lift the rear of the upper tailgate body 1 upward, and the traction component 3 is used to pull the upper tailgate body 1 forward to the roof of the vehicle. It also includes a traction drive component connected to the traction component 3 and the support component 2 respectively. The lower tailgate unit includes a lower tailgate body 6 rotatably connected to the vehicle body and a telescopic drive component rotatably connected to the lower tailgate body 6. The telescopic drive component is also rotatably connected to the vehicle body.

[0043] Compared with the prior art, the tailgate assembly provided by this utility model allows both the upper tailgate unit and the lower tailgate unit to be opened independently. When the upper tailgate unit is opened, the support component 2 first raises the rear of the upper tailgate body 1 to be level with or higher than the front. The traction drive component drives the traction component 3 forward, thereby moving the upper tailgate body 1 forward. While the upper tailgate body 1 moves forward, the support component 2 remains stationary. When the front of the upper tailgate body 1 moves above the roof, the support component 2 corresponds to the rear of the upper tailgate body 1. The traction drive component no longer drives the traction component 3, but instead drives the support component 2 to rotate forward, controlling the upper tailgate body 1 to continue moving forward until it is completely above the roof. When the lower tailgate body 6 is opened, the telescopic drive component extends and rotates relative to the vehicle body and the lower tailgate body 6, flipping the lower tailgate body 6 downwards to open. This utility model allows for the independent opening of both the upper tailgate body 1 and the lower tailgate body 6, enabling flexible opening according to actual conditions. Furthermore, when the tailgate body 1 is opened, not only can the support assembly 2 flip the tailgate body 1 upwards, but the traction assembly 3 can also move the tailgate body 1 to the roof of the vehicle, completely opening the top of the trunk and increasing the space for items to enter and exit the trunk. The tailgate body 1 in this invention does not need to flip upwards at an excessive angle, requiring less space above the vehicle and making it easier to retrieve and place larger items.

[0044] Optionally, the telescopic drive assembly is a telescopic strut, not shown in the figure.

[0045] In some embodiments, please refer to Figures 8 to 9 The lower tailgate unit also includes a locking assembly connected to the lower tailgate body 6. The locking assembly includes a mounting bracket 7 and a lock 8. The mounting bracket 7 includes a fixing part 701 connected to the lower tailgate body 6 and a mounting part connected to the fixing part 701 at an angle. The mounting part extends to the front side of the lower tailgate body 6. The lock 8 is connected to the mounting part and is used to lock with a latch on the vehicle body.

[0046] The fixing part 701 is attached to and connected to the lower tailgate body 6, increasing the contact area with the lower tailgate body 6. The mounting part extends to the front side of the lower tailgate body 6, and the lock 8 is installed on the mounting part to avoid interference with the lower tailgate body 6. In this embodiment, after the lower tailgate body 6 is closed, it is locked by the latch with the vehicle body, which improves the firmness of the lower tailgate body 6 after locking. This not only avoids the lower tailgate body 6 from contacting the vehicle body and generating noise during vehicle operation, but also avoids the lower tailgate body 6 being accidentally opened due to contact with the upper tailgate body 1 when it is closed.

[0047] In some embodiments, please refer to Figure 9 The mounting part includes a mounting plate 702 connected to the fixing part 701 and a mounting hook 703 connected to the mounting plate 702. The mounting hook 703 passes through the mounting hole of the lock 8.

[0048] The mounting hook 703 achieves a fixed connection with the lock 8 by plugging it in and providing a support point for the lock 8. Compared with the solution of directly connecting the lock 8 to the mounting plate 702, there is no need to introduce external connecting parts, which simplifies the installation steps of the lock 8.

[0049] In some embodiments, please refer to Figure 8 The lower tailgate body 6 includes an outer lower tailgate panel, a reinforcing plate 602, and an inner lower tailgate panel 601 arranged sequentially from the outside to the inside. The inner lower tailgate panel 601 has a clearance hole 6011. A fixing part 701 is connected to the reinforcing plate 602, and a mounting part extends through the clearance hole 6011 to the front side of the inner lower tailgate panel 601.

[0050] Since the strength and rigidity of the lower tailgate reinforcement plate 602 are superior to those of the lower tailgate inner plate 601, connecting the mounting bracket 7 to the tailgate reinforcement plate eliminates the need for additional reinforcement components, thus contributing to the overall vehicle weight reduction. Furthermore, the lower tailgate reinforcement plate 602 is located within the cavity formed by the lower tailgate inner plate 601 and the lower tailgate outer plate. Both the fixing part 701 and the rear end of the mounting part of the mounting bracket 7 are located within this cavity. This eliminates the need for excessively deep grooves on the lower tailgate reinforcement plate 602 to provide mounting space for the mounting bracket 7, reducing manufacturing difficulty and minimizing the space occupied inside the trunk.

[0051] In some embodiments, please refer to Figures 3 to 4 The traction drive assembly includes a front drive mechanism 4 and a rear drive mechanism 5. The front drive mechanism 4 includes a front drive module 401 located on the vehicle body and a front flexible shaft 402 connected to the front drive module 401. The rear part of the front flexible shaft 402 is connected to the traction assembly 3. The rear drive mechanism 5 includes a rear drive module 501 located on the vehicle body and a rear flexible shaft 502 connected to the rear drive module 501. The rear part of the rear flexible shaft 502 is connected to the support assembly 2.

[0052] The flexible shaft has a certain degree of rigidity, which can not only pull the upper tailgate body 1 forward, but also apply a thrust to the upper tailgate body 1 to reset it. Moreover, the flexible shaft has both deformability and rigidity, making the upper tailgate body 1 more stable during movement.

[0053] In some embodiments, please refer to Figures 3 to 4 Both the front flexible shaft 402 and the rear flexible shaft 502 are provided with a drive rack along their own axial direction. Both the front drive module 401 and the rear drive module 501 include a driver and a transmission gear connected to the driver. The transmission gear meshes with the drive rack.

[0054] The driver controls the rotation of the transmission gear, and the drive rack meshing with the transmission gear moves, thereby enabling the front flexible shaft 402 to pull or push the traction component 3 and the rear flexible shaft 502 to push the support component 2. The solution in this embodiment is simple, using the movement of the front flexible shaft 402 and the rear flexible shaft 502 to achieve forward traction or backward pushing, without the need for too many transmission components, thus simplifying the structure.

[0055] Optionally, both the front flexible shaft 402 and the rear flexible shaft 502 include a connecting part arranged in the front-to-back direction and a driving part arranged in the left-to-right direction. Since the flexible shaft has a certain deformation capacity, as the driving part moves in the left-to-right direction, it can drive the connecting part to move in the front-to-back direction, thereby realizing the forward traction or backward push of the traction component 3 or the support component 2.

[0056] Specifically, the vehicle has a clearance space on its roof, and when the traction assembly 3 or the support assembly 2 is pulled forward, the drive unit is moved into the clearance space.

[0057] Optionally, both the traction assembly 3 and the support assembly 2 are provided in two sets, symmetrically arranged on both sides of the upper tailgate body 1 along the left-right direction. The front flexible shaft 402 is arranged one-to-one with the traction assembly 3, and the rear flexible shaft 502 is arranged one-to-one with the support assembly 2. The two front flexible shafts 402 are located on opposite sides of the transmission gear of the front drive module 401, and the two rear flexible shafts 502 are located on opposite sides of the transmission gear of the rear drive module 501. The two sets of front flexible shafts 402 move in opposite directions, and the two sets of rear flexible shafts 502 move in opposite directions, thereby synchronously tractioning the upper tailgate body 1.

[0058] Optionally, the transmission gear can be replaced with a turbine, and the drive rack can be a thread adapted to the turbine.

[0059] In some embodiments, please refer to Figures 4 to 7The traction assembly 3 includes a traction rail 301, a sliding member 303, and a hinge member 302. The traction rail 301 is located on the vehicle body in the front-rear direction and is located in front of the upper tailgate body 1. The sliding member 303 is slidably connected to the traction rail 301 in the front-rear direction. The sliding member 303 is also connected to the traction drive assembly, which is used to drive the sliding member 303 to slide along the traction rail 301. The hinge member 302 is rotatably or slidably connected to the sliding member 303 and rotatably connected to the front of the upper tailgate body 1. The hinge member 302 is used to realize the raising or lowering of the upper tailgate body 1.

[0060] When the trunk needs to be opened, the hinge 302 rotates around or slides along the slider 303 to raise the upper tailgate body 1 above the trunk. The support assembly 2 drives the upper tailgate body 1 to rotate around the hinge 302, causing the rear of the upper tailgate body 1 to flip upwards until the rear of the upper tailgate body 1 is not lower than the front. Then, the slider 303 slides forward along the traction rail 301, sliding the upper tailgate body 1 directly above the roof, thus opening the trunk. Conversely, when closing the upper tailgate body 1, it first slides backwards to the rear of the roof. Then, the support assembly 2 drives the upper tailgate body 1 to rotate around the hinge 302, causing the rear of the upper tailgate body 1 to flip downwards to its lowest point. Finally, the hinge 302 rotates or slides to lower the upper tailgate body 1 to close the trunk opening. This invention allows for easy access to the trunk without occupying excessive space at the rear or top of the vehicle when opening the tailgate body 1. The tailgate body 1 is simply raised above the roof and then slid forward until it aligns with the roof, enabling easy access to items from the trunk. Furthermore, because the tailgate body 1 is positioned above the roof after opening, the trunk is fully open, allowing even larger items to be easily loaded and unloaded, thus improving user convenience.

[0061] In some embodiments, please refer to Figure 5 The sliding member 303 has a sliding groove 3031, and the rear part of the sliding groove 3031 has a lifting area. The tail end of the lifting area is inclined upward. The hinge member 302 has a sliding end that is slidably inserted into the sliding groove 3031 and a hinge end that is rotatably connected to the upper back door body 1.

[0062] When the upper tailgate body 1 is closed, the sliding end is located at the front end of the lifting area. When the upper tailgate body 1 is opened, the sliding end moves to the rear end of the lifting area, thereby lifting the upper tailgate body 1.

[0063] Optionally, the sliding end is a circular block structure. When the upper tailgate body 1 is opened, the upper tailgate body 1 can be rotated upward first (the sliding end rotates within the slide groove 3031), and then the upper tailgate body 1 can be pulled upward and backward (the sliding end moves upward and backward towards the slide groove 3031) to lift the upper tailgate body 1.

[0064] Optionally, when the upper tailgate body 1 is opened, the sliding member 303 slides forward, thereby driving the sliding end located in the slide groove 3031 to move upward in the lifting area, thereby lifting the upper tailgate body 1. In this embodiment, the sliding member 303 can be driven by pulling a driver, for example, by using the extension and retraction of a pneumatic cylinder or hydraulic cylinder to achieve the sliding of the sliding member 303, or by using a motor-driven flexible shaft to achieve the forward traction and backward push of the sliding member 303.

[0065] In some embodiments, please refer to Figures 4 to 7 The support component 2 includes a guide mechanism and a support mechanism. The guide mechanism is located on the upper tailgate body 1 in the front-rear direction. The support mechanism includes a connector 204 that is slidably connected to the guide mechanism in the front-rear direction and a support 201 that is rotatably connected to the connector 204. The support 201 is also rotatably connected to the vehicle body.

[0066] When the upper tailgate body 1 is opened, the connector 204 slides forward along the guide mechanism, and the support 201 lifts the upper tailgate body 1 upward until the rear of the upper tailgate body 1 is not lower than the front. Conversely, when the upper tailgate body 1 is closed, the connector 204 slides backward along the guide mechanism, the angle between the support 201 and the upper tailgate body 1 decreases, and the rear of the upper tailgate body 1 flips downward. In this embodiment, the movement of the connector 204 achieves the traction of the support 201, thereby opening or closing the upper tailgate body 1.

[0067] As one specific embodiment of the support member 201, the support member 201 is a telescopic member, and the fixed end of the support member 201 is rotatably connected to the vehicle body, and the telescopic end of the support member 201 is rotatably connected to the connector 204.

[0068] When the upper tailgate body 1 is opened, the support member 201 extends, and at the same time, the fixed end and the telescopic end of the telescopic member rotate. The telescopic end drives the connecting member 204 to slide forward, thereby flipping the upper tailgate body 1 upward. Conversely, when the support member 201 is closed, it returns to its original position, and the upper tailgate body 1 flips downward.

[0069] Optionally, the support member 201 can be a pneumatic or hydraulic telescopic member.

[0070] As one specific implementation of the conductor mechanism, please refer to Figure 7 The guiding mechanism includes a first guide rail 202 and a second guide rail 203 that are parallel to each other. The first guide rail 202 is connected to the vehicle body, and the second guide rail 203 is connected to the upper tailgate body 1. It also includes a traction member 205 that is slidably connected to the first guide rail 202 and the support member 201, and a connecting member 204 that is slidably connected to the second guide rail 203.

[0071] The traction component 205 is slidably connected to the first guide rail 202 and the support component 201. When the traction machine slides back and forth along the first guide rail 202, it simultaneously slides along the support component 201, thereby pulling the support component 201 along the second guide rail 203 with the connecting component 204, thus lifting or lowering the upper tailgate body 1. In this embodiment, the sliding of the traction component 205 drives the support component 201, thereby controlling the flipping of the upper tailgate body 1.

[0072] Optionally, the first guide rail 202 and the second guide rail 203 are distributed along the vertical or horizontal direction.

[0073] Optionally, the support member 201 and / or the first guide rail 202 are provided with a stop position. When the traction member 205 moves to the foremost end of the first guide rail 202, the traction member 205 is in the stop position, which can keep the rear end of the upper tail door body 1 in an open state. For example, the stop position can be a locking groove. The traction member 205 is located in the locking groove to fix the upper tail door body 1 in the open state. When an external force is applied to the upper tail door body 1, the traction member 205 moves out of the locking groove, and the upper tail door body 1 flips downward.

[0074] Based on the same inventive concept, this utility model also provides a vehicle. Please refer to [link / reference]. Figure 1 The vehicle includes a tailgate assembly.

[0075] The vehicle provided by this utility model adopts the aforementioned tailgate assembly, in which both the upper tailgate unit and the lower tailgate unit can be opened independently. When the upper tailgate unit is opened, the support assembly 2 first raises the rear of the upper tailgate body 1 to be level with or higher than the front. The traction drive assembly drives the traction assembly 3 forward, thereby moving the upper tailgate body 1 forward. While the upper tailgate body 1 moves forward, the support assembly 2 remains stationary. When the front of the upper tailgate body 1 moves above the roof, the support assembly 2 corresponds to the rear of the upper tailgate body 1. The traction drive assembly no longer drives the traction assembly 3, but instead drives the support assembly 2 to rotate forward, controlling the upper tailgate body 1 to continue moving forward until the upper tailgate body 1 is completely above the roof. When the lower tailgate body 6 is opened, the telescopic drive assembly extends and rotates relative to the vehicle body and the lower tailgate body 6, flipping the lower tailgate body 6 downwards to open. This utility model allows for the independent opening of the upper tailgate body 1 and the lower tailgate body 6, enabling flexible opening according to actual conditions. Furthermore, when the tailgate body 1 is opened, not only can the support assembly 2 flip the tailgate body 1 upwards, but the traction assembly 3 can also move the tailgate body 1 to the roof of the vehicle, completely opening the top of the trunk and increasing the space for items to enter and exit the trunk. The tailgate body 1 in this invention does not need to flip upwards at an excessive angle, requiring less space above the vehicle and making it easier to retrieve and place larger items.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
