Description

Technical Field

[0001] This utility model belongs to the field of vehicle tailgate technology, specifically relating to a tailgate opening and closing structure assembly and a vehicle. Background Technology

[0002] Hatchback tailgates are widely used in SUVs and other hatchback vehicles, primarily due to their simple design, lower production costs, and convenient opening and closing. However, existing hatchback tailgates have a rear flap that sits above the trunk opening. When loading or unloading larger items, extra care must be taken to avoid bumping the tailgate, compromising the convenience of accessing large items. Furthermore, because the tailgate obstructs the trunk space, it limits the openness of the rear cargo area, requiring users to avoid bumping into the tailgate when standing behind the vehicle to retrieve items, thus impacting the user experience. Utility Model Content

[0003] This utility model provides a tailgate opening and closing structure assembly and vehicle, aiming to solve the problem that the existing tailgate opening and closing method affects the openness of the space behind the vehicle, making it inconvenient to load and unload large items, and making it inconvenient for users to stand behind the vehicle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] In a first aspect, embodiments of the present invention provide a rear tailgate opening and closing structure assembly, comprising:

[0006] Rear door;

[0007] The guide rail is located on the top of the side panel assembly and extends along the top outline of the side panel assembly;

[0008] A front lifting rod device has a front sliding end that slides with the guide rail and a front hinge end that hinges to the front of the side of the tailgate; the front lifting rod device has a folded state and a raised state. In the folded state, the upper edge of the tailgate is aligned with the upper edge of the trunk opening; in the raised state, the upper edge of the tailgate extends upward above the roof.

[0009] The rear lift rod device has a rear sliding end that slides with the guide rail and a rear hinge end that hinges to the rear side of the tailgate. The rear lift rod device is a telescopic device. The rear lift rod device has a folded-down state and an extended-up state. In the folded-down state, the lower edge of the tailgate is aligned with the lower edge of the trunk opening. In the extended-up state, the lower edge of the tailgate extends upward above the roof.

[0010] When the tailgate is closed, the front lifting lever device is in a folded state, and the rear lifting lever device is in a folded and retracted state.

[0011] When the tailgate is fully open, the tailgate is above the roof.

[0012] Compared with the prior art, the solution shown in this application embodiment, when the tailgate is closed, the front lifting rod device is in a folded state and the rear lifting rod device is in a folded-back state. At this time, the front hinge end of the front lifting rod device and the rear hinge end of the rear lifting rod device are both tilted backward. When it is necessary to open the door, the front lifting rod device is controlled to switch from the folded state to the extended state, so that the upper edge of the tailgate is raised upward. At the same time, the rear lifting rod device is controlled to switch from the folded-back state to the extended-back state, so that the lower edge of the tailgate is raised upward. When the tailgate is higher than the ceiling, the tailgate presents a posture of higher back and lower front. At this time, the front lifting rod device and the rear lifting rod device move forward along the guide rail at the same time until the tailgate is above the ceiling, and the door opening operation is completed. The reverse operation can realize the door closing operation. This application enables the tailgate to open by first lifting and then sliding forward. Once opened, the tailgate offers virtually no obstruction of the space above the trunk, resulting in greater trunk openness. Users can place items of various heights in the trunk after the tailgate is open, making it easier to retrieve large items. It also avoids the problem of people bumping into the tailgate when standing behind the car to retrieve items, ensuring that users are not affected while standing behind the car, thus providing a better user experience.

[0013] In conjunction with the first aspect, in one possible implementation, the front lifting rod device includes a front lifting rod, a front sliding seat, and a front hinge seat; one end of the front lifting rod is rotatably connected to the front sliding seat, which forms the front sliding end; the other end of the front lifting rod is hinged to the front hinge seat, which is located on the tailgate. The front sliding seat provides a stable sliding base for the entire front lifting rod device, and the front hinge seat provides a flexible connection between the front lifting rod and the tailgate, facilitating adjustment of the posture of the front lifting rod and the tailgate during lifting or lowering. The overall structure of the front lifting rod device is simple and easy to use.

[0014] In some embodiments, the end of the front lifting rod is provided with a slider, and the front sliding seat is provided with a lifting groove. The lifting groove is set at an angle to the guide rail, and the lifting groove is inclined upward relative to the guide rail. The slider is slidably adapted to the lifting groove. In the folded state, the slider is at the front end of the lifting groove, and in the extended state, the slider is at the rear end of the lifting groove. In use, the front sliding seat is first moved forward, and the slider can slide in the lifting groove, thus lifting the front lifting rod. Combined with the extension of the rear lifting rod device, the entire tailgate is lifted, and the structure of the front lifting rod device is simpler.

[0015] In some embodiments, the tailgate opening and closing structure assembly further includes a front sliding drive device, which is tractively connected to the front sliding seat to drive the front sliding seat to move back and forth along the guide rail.

[0016] In some embodiments, the front sliding seat and the guide rail are distributed in the left-right direction, reducing the vertical dimension and avoiding interference with the opening and closing of the tailgate. The front sliding seat has a front drive protrusion on the side facing the guide rail, and the guide rail has a drive groove. The front drive protrusion slides into the drive groove. The front sliding drive device is a flexible shaft sliding drive device, with its drive end inserted into the drive groove and connected to the front drive protrusion. By using a flexible shaft drive device, the main body of the flexible shaft drive device can be flexibly positioned on the top of the vehicle body. For example, the main body of the flexible shaft drive device can be positioned at the front of the vehicle body, with the flexible shaft turning and extending rearward along the edge of the roof to connect with the front sliding seat. This fully utilizes the internal space of the roof, avoids affecting the movement of the sliding seat, and the flexible shaft can also drive the front sliding seat to reciprocate along the guide rail.

[0017] In conjunction with the first aspect, in one possible implementation, the rear lifting rod device includes a rear lifting rod, a rear sliding seat, and a rear hinge seat. The rear lifting rod is a telescopic rod, one end of which is hinged to the rear sliding seat, forming the rear sliding end. The other end of the rear lifting rod is hinged to the rear hinge seat, which is located on the tailgate. The rear sliding seat provides a stable sliding base for the entire rear lifting rod device, and the rear hinge seat allows for a flexible connection between the rear lifting rod and the tailgate, facilitating adjustment of the posture of the rear lifting rod and the tailgate during lifting or lowering. The overall structure of the rear lifting rod device is simple and easy to use.

[0018] In some embodiments, the tailgate opening and closing structure assembly further includes a rear sliding drive device, which is tractively connected to the rear sliding seat to drive the rear sliding seat to reciprocate along the guide rail.

[0019] In some embodiments, the rear lifting rod is a hydraulic telescopic rod, which gives the rear lifting rod a stronger load-bearing capacity and facilitates stable support of the rear door after extension.

[0020] In some embodiments, a support hinge seat is also provided on the upper side of the rear sliding seat, the main body of the rear lifting rod is hinged to the support hinge seat, and the piston rod of the rear lifting rod is hinged to the rear hinge seat. The support hinge seat enables the rear lifting rod to be hinged to the upper side of the rear sliding seat, avoiding the occupation of space on the left and right sides of the sliding seat, and making the side panel design simpler.

[0021] Secondly, this utility model embodiment also provides a vehicle including the aforementioned tailgate opening and closing structure assembly.

[0022] Compared with the prior art, the solution shown in this application embodiment, by adopting the above-mentioned tailgate opening and closing structure assembly, enables the tailgate to achieve the opening process of first lifting and then sliding forward. After the tailgate is opened, there is basically no obstruction to the space above the trunk, the trunk has greater openness, and users can place items of various heights in the trunk after the tailgate is opened, making it more convenient to retrieve large items. It also avoids the problem of people bumping into the tailgate when standing behind the car, and users are not affected when standing behind the car, resulting in a better user experience.

[0037] Please refer to the following: Figures 1 to 4The rear tailgate opening and closing structure assembly provided by this utility model will now be described. The rear tailgate opening and closing structure assembly includes a rear tailgate 1, a guide rail 2, a front lifting rod device 3, and a rear lifting rod device 4; the guide rail 2 is located on the top of the side panel assembly and extends along the top contour line of the side panel assembly; the front lifting rod device 3 has a front sliding end that slides with the guide rail 2, and also has a front hinge end that hinges to the front of the side of the rear tailgate 1; the front lifting rod device 3 has a folded state and a raised state. In the folded state, the upper edge of the rear tailgate 1 is aligned with the upper edge of the trunk opening; in the raised state, the upper edge of the rear tailgate 1 extends upward above the roof 5. The rear lift rod device 4 has a rear sliding end that slides into the guide rail 2, and a rear hinge end that hinges to the rear side of the tailgate 1. The rear lift rod device 4 is a telescopic device. The rear lift rod device 4 has a folded-down state and a stretched-out state. In the folded-down state, the lower edge of the tailgate 1 aligns with the lower edge of the trunk opening. In the stretched-out state, the lower edge of the tailgate 1 extends upwards above the roof 5. When the tailgate 1 is closed, the front lift rod device 3 is in a folded state, and the rear lift rod device 4 is in a folded-down state. Figure 1 As shown; when the rear door 1 is flipped open, the front lifting rod device 3 is in the supported state, and the rear lifting rod device 4 is in the supported extended state, as shown. Figure 2 As shown; when the tailgate 1 is fully open, the tailgate 1 is positioned above the roof 5, as... Figure 3 As shown.

[0038] The front sliding end can not only slide but also rotate relative to the guide rail. Similarly, the rear sliding end can not only slide but also rotate relative to the guide rail 2, thereby realizing the folding of the front lifting rod device 3 and the rear lifting rod device 4.

[0039] In this embodiment, a front lifting rod device 3 is provided on the left and right sides of the front of the tailgate 1, and a rear lifting rod device 4 is provided on the left and right sides of the rear of the tailgate 1, so as to realize the stable lifting and sliding of the tailgate 1 and make the structure as simple as possible while ensuring the reliability of use.

[0040] Compared with the prior art, the tailgate opening and closing structure assembly provided in this embodiment, when the tailgate 1 is closed, has the front lifting rod device 3 in a folded state and the rear lifting rod device 4 in a folded and retracted state. At this time, both the front hinge end of the front lifting rod device 3 and the rear hinge end of the rear lifting rod device 4 are tilted backward (e.g., Figure 1(As shown); when the door needs to be opened, the front lifting lever device 3 switches from the folded state to the extended state, causing the upper edge of the tailgate 1 to lift upwards. Simultaneously, the rear lifting lever device 4 switches from the folded retracted state to the extended extended state, causing the lower edge of the tailgate 1 to lift upwards, and the tailgate 1 opens upwards. When the tailgate 1 is higher than the roof 5, the tailgate 1 presents a rear-high, front-low posture (as shown). Figure 2 As shown), at this time, the front lifting rod device 3 and the rear lifting rod device 4 move forward along the guide rail 2 simultaneously until the rear door 1 is above the ceiling 5 (as shown). Figure 3 As shown, the tailgate 1 is fully open, and the opening operation is complete; the reverse operation is used to close the tailgate. This embodiment enables the tailgate 1 to open by first lifting and then sliding forward. After the tailgate 1 is opened, it basically does not obstruct the space above the trunk, making the trunk more open. Users can place items of various heights in the trunk after the tailgate 1 is open, making it more convenient to retrieve large items. It also avoids the problem of people standing behind the car bumping into the tailgate 1 when retrieving items. Users can stand behind the car without being affected, resulting in a better user experience.

[0041] It should be noted that when the rear door 1 is propped up, both its upper and lower edges are higher than the roof 5, meaning that both the upper and lower edges of the rear door 1 are higher than the rear edge of the roof 5.

[0042] In some embodiments, see Figure 4 The front lifting rod device 3 includes a front lifting rod 310, a front sliding seat 320, and a front hinge seat 330. One end of the front lifting rod 310 is rotatably connected to the front sliding seat 320, forming a front sliding end. The other end of the front lifting rod 310 is hinged to the front hinge seat 330, which is located on the tailgate 1. The front sliding seat 320 provides a stable sliding base for the entire front lifting rod device 3, and the front hinge seat 330 provides a flexible connection between the front lifting rod 310 and the tailgate 1, facilitating adjustment of the posture of the front lifting rod 310 and the tailgate 1 during lifting or lowering. The overall structure of the front lifting rod device 3 is simple and easy to use. Based on this, the tailgate opening and closing structure assembly also includes a front sliding drive device, which is connected to the front sliding seat 320 to drive the front sliding seat 320 to move back and forth along the guide rail 2.

[0043] In other embodiments, see Figure 5 and Figure 6The front lifting rod 310 has a slider 340 at its end, and the front sliding seat 320 has a lifting groove 350. The lifting groove 350 is set at an angle to the guide rail 2, and the lifting groove 350 is inclined upward relative to the guide rail 2. The slider 340 and the lifting groove 350 are slidably adapted. In the folded state, the slider 340 is at the front end of the lifting groove 350, and in the supported state, the slider 340 is at the rear end of the lifting groove 350. In use, the front sliding seat 320 is moved forward first, and the slider 340 can slide in the lifting groove 350, and the front lifting rod 310 is lifted. Combined with the extension of the rear lifting rod device 4, the entire tailgate 1 is lifted. The swing of the front lifting rod 310 can be satisfied without the need for an electronically controlled drive device, and the structure of the front lifting rod device 3 is simpler.

[0044] Based on the above embodiments, the rear door opening and closing structure assembly also includes a front sliding drive device, which is connected to the front sliding seat 320 to drive the front sliding seat 320 to move back and forth along the guide rail 2.

[0045] In some embodiments, see Figure 7 The front sliding seat 320 and the guide rail 2 are distributed in the left-right direction, reducing the size in the vertical direction to avoid affecting the opening and closing of the rear door 1. Based on this, the front sliding seat 320 has a front drive protrusion 321 on the side facing the guide rail 2, and the guide rail 2 has a drive groove 201. The front drive protrusion 321 and the drive groove 201 are slidably adapted to each other. The front sliding drive device is a flexible shaft sliding drive device, whose drive end passes through the drive groove 201 and connects to the front drive protrusion 321. The flexible shaft in the front sliding drive device is bendable and can connect to components that are not in the same direction as the main body of the flexible shaft drive device to move the target object. By adopting a flexible shaft drive device, the main body of the flexible shaft drive device can be flexibly set on the top of the vehicle body. For example, the main body of the flexible shaft drive device can be set at the front of the vehicle body, and the flexible shaft can bend and extend along the edge of the roof 5 to the rear of the vehicle body to connect with the front sliding seat 320. This makes full use of the interior space of the roof 5 and avoids affecting the movement of the sliding seat. The flexible shaft can also drive the front sliding seat 320 to move back and forth along the guide rail 2.

[0046] Other implementations of the forward sliding drive mechanism are shown below:

[0047] 1) The front sliding drive device includes a drive motor, a drive gear connected to the output shaft of the drive motor, and a rack on the guide rail 2 and extending along the long axis of the guide rail 2. The drive motor is fixed on the front sliding seat 320. The drive motor drives the drive gear to rotate, and the drive gear meshes with the rack, thereby realizing the front sliding seat 320 moving back and forth.

[0048] 2) The front sliding drive device includes a drive motor, a drive sprocket connected to the output shaft of the drive motor, and a chain extending forward and backward on the guide rail 2. The drive motor is fixed on the front sliding seat 320. The drive motor drives the drive sprocket to rotate, and the drive sprocket meshes with the chain, thereby realizing the forward and backward movement of the front sliding seat 320. A tensioning wheel is provided inside the guide rail 2, which is supported between the guide rail 2 and the chain to maintain a certain tension on the chain, facilitating engagement with the drive sprocket.

[0049] Optional, see Figure 7 The front drive protrusion 321 includes a connecting section 3211 and a drive connecting section 3212. The connecting section 3211 is connected to the front sliding seat 320. The width of the drive connecting section 3212 is greater than the width of the connecting section 3211, so as to provide a larger connection area at the connection of the flexible shaft. The drive groove 201 is configured to conform to the shape of the front drive protrusion 321.

[0050] In some embodiments, see Figure 4 The rear lifting rod device 4 includes a rear lifting rod 410, a rear sliding seat 420, and a rear hinge seat 430. The rear lifting rod 410 is a telescopic rod, with one end hinged to the rear sliding seat 420, forming a rear sliding end. The other end of the rear lifting rod 410 is hinged to the rear hinge seat 430, which is located on the tailgate 1. The rear sliding seat 420 provides a stable sliding base for the rear lifting rod device 4, and the rear hinge seat 430 provides a flexible connection between the rear lifting rod 410 and the tailgate 1, facilitating adjustment of the posture of the rear lifting rod 410 and the tailgate 1 during lifting or lowering. The rear lifting rod device 4 has a simple overall structure and is easy to use.

[0051] Based on the above embodiments, the tailgate opening and closing structure assembly also includes a rear sliding drive device, which is connected to the rear sliding seat 420 to drive the rear sliding seat 420 to reciprocate along the guide rail 2. The implementation of the rear sliding drive device and its adaptation to the guide rail 2 are similar to those of the front sliding drive device, and will not be described in detail here.

[0052] In some embodiments, the rear lift rod 410 is a hydraulic telescopic rod, which gives the rear lift rod 410 a stronger load-bearing capacity and facilitates stable support of the tailgate 1 after extension. Of course, the rear lift rod 410 can also be a pneumatic telescopic rod, an electric actuator, etc., which will not be listed here.

[0053] Based on the above embodiments, see Figure 4The upper side of the rear sliding seat 420 is also provided with a support hinge seat 440. The main body of the rear lifting rod 410 is hinged to the support hinge seat 440, and the piston rod of the rear lifting rod 410 is hinged to the rear hinge seat 430. The support hinge seat 440 enables the rear lifting rod 410 to be hinged to the upper side of the rear sliding seat 420, avoiding the occupation of space on the left and right sides of the sliding seat, and making the side panel design simpler.

[0054] In some specific embodiments, the front lifting rod 310 is hinged to the front sliding seat 320, but the front lifting rod 310 does not translate relative to the front sliding seat 320. The lifting or lowering of the upper edge of the tailgate 1 is achieved by the swinging of the apex of the front lifting rod 310. Based on the fact that there is only a rotational connection between the front lifting rod 310 and the front sliding seat 320, the front lifting rod device 3 is also provided with a front lifting drive assembly, which is used to drive the front lifting rod 310 to swing back and forth. The implementation methods of the front lifting drive assembly include, but are not limited to, the following:

[0055] 1-1) The front lifting drive assembly is located between the front sliding seat 320 and the front lifting rod 310. It includes a front lifting driver, a front lifting drive gear, and a front lifting driven gear. The front lifting driver is mounted on the front sliding seat 320, and its output shaft is perpendicular to the front lifting rod 310. The front lifting drive gear is mounted on its output shaft, and the front lifting driven gear is mounted on the front lifting rod 310. The drive gear and driven gear mesh to achieve gear transmission, thereby controlling the rotation of the front lifting rod 310 through the front lifting driver, thus switching the state of the front lifting rod 310. The implementation of the front lifting driver may include, but is not limited to, a servo motor.

[0056] 1-2) The front lifting drive assembly is located between the front sliding seat 320 and the front lifting rod 310. It includes a front lifting driver, a front lifting worm gear, and a front lifting worm. The front lifting driver is mounted on the front sliding seat 320, and its output shaft is in the same vertical plane as the front lifting rod 310. The front lifting worm is mounted on the output shaft of the front lifting driver, and the front lifting worm gear is mounted on the front lifting rod 310. The worm gear meshes with the worm gear to achieve worm gear transmission, thereby controlling the rotation of the front lifting rod 310 through the front lifting driver, thus switching the state of the front lifting rod 310. The implementation of the front lifting driver includes, but is not limited to, a servo motor.

[0057] 1-3) The front lifting drive assembly is located between the front sliding seat 320 and the front lifting rod 310. It includes a front lifting driver, a front lifting drive sprocket, a front lifting driven sprocket, and a front lifting chain. The front lifting driver is mounted on the front sliding seat 320, and its output shaft is perpendicular to the front lifting rod 310. The front lifting drive sprocket is mounted on the output shaft of the front lifting driver, and the front lifting driven sprocket is mounted on the front lifting rod 310. The front lifting chain winds between the front lifting drive sprocket and the front lifting driven sprocket to achieve chain drive. The front lifting driver then controls the rotation of the front lifting rod 310, thus switching the state of the front lifting rod 310. The implementation of the front lifting driver includes, but is not limited to, a servo motor.

[0058] 1-4) The front lifting drive assembly includes a winch, which is mounted on the front sliding seat 320 or the front sliding drive device. The traction rope on the winch is connected to the front lifting rod 310 near the front hinge end. The front lifting rod 310 is raised by winding the traction rope, and the front lifting platform is lowered by releasing the traction rope in combination with the gravity of the front lifting rod 310.

[0059] Based on the above implementation methods 1-1) to 1-4), during the switching state of the front lifting lever 310, the rear lifting lever 410 gradually extends to raise the lower edge of the tailgate 1. After both the upper and lower edges of the tailgate 1 are higher than the roof 5, the front sliding drive device drives the front sliding seat 320 to move forward along the guide rail 2, and at the same time, the rear sliding drive device drives the rear sliding seat 420 to move forward along the guide rail 2, thereby causing the tailgate 1 to move forward as a whole until it moves to a designated position above the roof 5 (e.g., Figure 3 (As shown).

[0060] In some other specific embodiments, based on the lifting groove 350, the front lifting rod 310 can achieve lifting and flipping as follows: When the tailgate 1 is closed, the front sliding drive device drives the front sliding seat 320 to move forward along the guide rail 2. At the same time, the rear lifting rod device 4 gradually extends. During the forward movement of the front sliding seat 320, the tailgate 1 and the front lifting rod 310 are restricted by the rear lifting rod device 4, so that the front lifting rod 310 does not move forward with the front sliding seat 320. At this time, the slider 340 moves backward relative to the lifting groove 350. The position of block 340 gradually rises, which in turn raises the position of the front lifting rod 310, thereby raising the upper edge of the tailgate 1 so that the upper edge of the tailgate 1 is higher than the roof 5. At the same time, as the rear lifting rod device 4 gradually extends, the lower edge of the tailgate 1 also gradually rises until the entire tailgate 1 is higher than the roof 5. Then, the front sliding drive device drives the front sliding seat 320 to move forward along the guide rail 2, and the rear sliding drive device drives the rear sliding seat 420 to move forward along the guide rail 2, thereby moving the entire tailgate 1 forward until it moves to the designated position above the roof 5.

[0061] In some embodiments, the rear sliding seat 420 and the guide rail 2 are distributed in the left-right direction. The rear sliding seat 420 has a rear drive protrusion on the side facing the guide rail 2, and the guide rail 2 has a drive groove 201. The rear sliding drive device is a flexible shaft sliding drive device, and its drive end passes through the drive groove 201 and is connected to the rear drive protrusion. The cooperation method between the rear drive protrusion and the drive groove 201 is similar to that of the aforementioned front drive protrusion 321, and will not be described again here.

[0062] Based on the same inventive concept, this application also provides a vehicle including the above-described tailgate opening and closing structure assembly.

[0063] Compared with the prior art, the vehicle provided in this embodiment, by adopting the above-mentioned tailgate opening and closing structure assembly, enables the tailgate 1 to achieve the opening process of first lifting and then sliding forward. After the tailgate 1 is opened, it basically does not obstruct the space above the trunk, and the trunk has a higher degree of openness.
