[0003] The existing hatchback design's tailgate will obstruct the space above the trunk when opened. When loading or unloading items, users need to be careful to bend over to avoid hitting the tailgate. At the same time, the tailgate will also affect the loading and unloading of large items, affecting the convenience of using the trunk. Utility Model Content

[0004] This utility model provides a tailgate opening and closing structure assembly and vehicle, aiming to solve the problem that the existing hatchback tailgate obstructs the space above the trunk after opening, affecting the convenience of using the trunk.

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

[0006] In a first aspect, embodiments of the present invention provide a rear door switch assembly, comprising:

[0007] Rear door body;

[0008] The first guide rail is located on the top of the side panel assembly and extends along the top outline of the side panel assembly.

[0009] The front lifting rod device has a side sliding end that slides with the first guide rail, and a tailgate front hinge end that hinges to the front of the side of the tailgate body; the front lifting rod device has a front folded state and a front extended state. In the front folded state, the upper edge of the tailgate body is aligned with the upper edge of the trunk opening; in the front extended state, the upper edge of the tailgate body extends upward above the roof.

[0010] The second guide rail extends along the side line of the rear door body;

[0021] In some embodiments, the end of the front support rod is provided with a slider, and the front slide is provided with a lifting groove. The lifting groove is set at an angle to the first guide rail, and the lifting groove is inclined upward relative to the first guide rail. The slider is slidably adapted to the lifting groove. In the front folded state, the slider is at the front end of the lifting groove, and in the front supported state, the slider is at the rear end of the lifting groove.

[0022] In some embodiments, the front slide block and the first guide rail are distributed in the left-right direction. The front slide block has a front drive protrusion on the side facing the first guide rail. The first guide rail has a drive groove. The front drive protrusion is slidably adapted to the drive groove. The tailgate switch assembly also includes a front sliding drive device. The front sliding drive device is a flexible shaft sliding drive device. Its drive end passes through the drive groove and is connected to the front drive protrusion.

[0023] In some embodiments, the front support rod is provided with a limiting member. When the posture of the front support rod corresponds to the front-supported state, the limiting member abuts against the front slide block to limit the upward tilt angle of the rear door body.

[0024] Secondly, this utility model embodiment also provides a vehicle including the aforementioned tailgate switch assembly.

[0046] Please refer to the following: Figures 1 to 4 The tailgate switch assembly provided by this utility model will now be described. The tailgate switch assembly includes a tailgate body 1, a first guide rail 2, a front lifting rod device 3, a second guide rail 4, and a rear lifting rod device 5. The first 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 side panel front sliding end that slides with the first guide rail 2, and a tailgate front hinge end that hinges to the front of the side of the tailgate body 1. The front lifting rod device 3 has a forward-folded state and a forward-supported state. In the forward-folded state, the upper edge of the tailgate body 1 aligns with the upper edge of the trunk opening; in the forward-supported state, the upper edge of the tailgate body 1 extends upward above the roof 6. The second guide rail 4 extends along the side line of the rear tailgate body 1; the rear lifting rod device 5 has a side sliding end that slides in conjunction with the first guide rail 2, and a rear sliding end that slides in conjunction with the second guide rail 4; the rear lifting rod device 5 has a folded state and a raised state. In the folded state, the lower edge of the rear tailgate body 1 is aligned with the lower edge of the trunk opening; in the raised state, the upper edge of the rear tailgate body 1 extends upward above the roof 6.

[0047] When the rear tailgate body 1 is closed, the front lifting rod device 3 is in a forward-folded state and the rear lifting rod device 5 is in a rear-folded state; when the rear tailgate body 1 is flipped open, the front lifting rod device 3 is in a forward-supported state and the rear lifting rod device 5 is in a rear-supported state; when the rear tailgate body 1 is fully open, the rear tailgate body 1 is located above the roof 6.

[0048] It should be noted that the front sliding end of the side of the front lifting rod device 3 is not only slidably connected to the first guide rail 2, but can also rotate relative to the first guide rail 2, thereby realizing the folding of the front lifting rod device 3. Similarly, the rear sliding end of the side of the rear lifting rod device 5 is not only slidably connected to the first guide rail 2, but can also rotate relative to the first guide rail 2, thereby realizing the folding of the rear lifting rod device 5.

[0049] Compared with the prior art, the tailgate switch assembly provided in this embodiment, when the tailgate body 1 is closed, has the front lifting rod device 3 in a forward-folded state and the rear lifting rod device 5 in a rear-folded state. Both the front hinge end of the front lifting rod device 3 and the rear sliding end of the rear lifting rod device 5 are tilted rearward (e.g., ...). Figure 1 (As shown); If it is necessary to open the door, control the front lifting lever device 3 to switch from the front-folded state to the front-supported state, so that the upper edge of the tailgate body 1 is raised upward. At the same time, control the rear lifting lever device 5 to switch from the rear-folded state to the rear-supported state, so that the lower edge of the tailgate is raised upward. The tailgate body 1 is in an upward flipped-open state until the tailgate body 1 is in a rear-high-front-low posture (as shown). Figure 2 (As shown); then the front lifting rod device 3 and the rear lifting rod device 5 move forward simultaneously along the guide rail until the rear door body 1 is above the ceiling 6, and the door opening operation is completed (as shown). Figure 3 (As shown); the reverse operation can be used to close the door. In this embodiment, after the tailgate flips over, it slides forward to the top of the roof 6. After the tailgate body 1 is fully opened, it will not obstruct the top of the trunk. The trunk has sufficient openness, and users can place large items more conveniently without having to bend over to take or put in items.

[0050] Optionally, after the tailgate body 1 moves above the roof 6, the rear lifting rod device 5 switches from the rear-supported state to the rear-folded state until the tailgate body 1 is relatively close to the roof 6, avoiding occupying too much space above the roof 6 (e.g., Figure 3 (As shown).

[0051] In some embodiments, see Figure 4 The rear lifting rod device 5 includes a first rear slide block 510, a rear support rod 520, and a second rear slide block 530. The first rear slide block 510 is slidably connected to the first guide rail 2, and the second rear slide block 530 is slidably connected to the second guide rail 4. One end of the rear support rod 520 is hinged to the first rear slide block 510, and the other end is hinged to the second rear slide block 530. In this embodiment, the length of the rear support rod 520 is fixed. The switching between the rear-folded state and the rear-supported state is achieved through sliding cooperation with the rear tailgate body 1. The rear lifting rod device 5 has a simple and compact structure and low operating cost.

[0052] It should be noted that, in order to maintain its structural stability, during the switching between the rear lifting rod device 5 in the rear folded state and the rear supported state, the position of the first rear slide block 510 relative to the first guide rail 2 remains unchanged, and the state switching is achieved only by adjusting the position of the second rear slide block 530 relative to the second guide rail 4.

[0053] In some embodiments, to realize the lifting function of the rear lifting lever device 5, the tailgate switch assembly further includes a rear sliding drive device and a rear lifting drive device. The rear sliding drive device is drivenly connected to the first rear slide block 510 to drive the first rear slide block 510 to move back and forth along the first guide rail 2; the rear lifting drive device is drivenly connected to the second rear slide block 530 to drive the second rear slide block 530 to move back and forth along the second guide rail 4. The rear lifting drive device operates to switch the rear lifting lever device 5 from a folded state to an extended state. After switching to the correct position, the rear lifting drive device stops operating. Subsequently, the rear sliding drive device operates to drive the rear lifting lever device 5 forward, which corresponds to the process of the tailgate body 1 moving forward as a whole. The rear sliding drive mechanism operates, causing the rear lifting lever device 5 to move backward, corresponding to the overall backward movement of the tailgate body 1. After moving above the trunk opening, the rear sliding drive mechanism stops, and the rear lifting drive mechanism operates to switch the rear lifting lever device 5 from the extended state to the folded state. Once switched into position, the rear lifting drive mechanism stops operating. The rear sliding drive mechanism and the rear lifting drive mechanism work together to make the operation of the rear lifting lever device more flexible and reliable.

[0054] Based on the provision of a rear sliding drive and a rear lifting drive, see [link / reference] Figure 12 and Figure 13 The first rear slide block 510 is equipped with a limit switch 540. When the rear support rod 520 swings to the position corresponding to the rear-raised state, the rear support rod 520 triggers the limit switch 540. The limit switch 540 is communicatively connected to the rear sliding drive device and the rear lifting drive device. Door opening process: According to the input commands from the control module such as the remote control and vehicle buttons, the rear lifting drive device operates to switch the rear lifting rod device 5 from the rear-folded state to the rear-raised state. After the rear support rod 520 triggers the limit switch 540, it is determined that the state switch of the rear lifting rod device 5 is completed. The limit switch 540 generates a completion command. The rear lifting drive device stops operating according to the completion command, and the rear sliding drive device starts according to the completion command to drive the rear lifting rod device 5 forward. During the closing process, based on input commands from control modules such as the remote control and vehicle buttons, the rear sliding drive mechanism operates to move the rear lifting lever device 5 backward. After moving above the trunk opening, the rear sliding drive mechanism stops, and the rear lifting drive mechanism operates to switch the rear lifting lever device 5 from the rear-supported state to the rear-folded state. Simultaneously, the toggle switch 541 of the limit switch 540 resets. By setting the limit switch 540, the intelligence level of the door opening action is improved, ensuring accurate and smooth door opening.

[0055] For specific settings of some limit switches 540, please refer to [link / reference]. Figure 12 and Figure 13The limit switch 540 is embedded in the first rear slide block 510. The first rear slide block 510 has an adjustment through hole 511, which is an elongated hole. The dial 541 of the limit switch 540 passes through the adjustment through hole 511, and the rear support rod 520 can move the dial 541 during the swinging process. The embedded design of the limit switch 540 can better protect the limit switch 540 and prevent it from directly hitting the rear support rod 520. In order for the rear support rod 520 to touch the dial 541, the adjustment through hole 511 is provided so that the dial 541 can pass through. The dial 541 has a first trigger state and a second trigger state. When the rear support rod 520 is in the folded state, the dial 541 is in the first trigger state and is located at the rear end of the adjustment through hole 511. When the rear support rod 520 is in the extended state, the dial 541 is in the second trigger state and is located at the front end of the adjustment through hole 511. Based on this, during the transition from the rear-folded state to the rear-supported state, the rear support rod 520 pushes the dial 541 to move. When the dial 541 moves to the front end of the adjustment through hole 511, the limit switch 540 signal changes, indicating that the state transition of the rear lifting rod device 5 is complete. During the transition from the rear-supported state to the rear-folded state, the rear support rod 520 swings backward, and the dial 541 moves backward accordingly, gradually returning to the first trigger state, waiting for the next state change to be triggered.

[0056] In some embodiments, an elastic element is provided between the switch body of the limit switch 540 and the toggle switch 541. The toggle switch 541 has a first trigger state and a second trigger state. When the rear support rod is in the position corresponding to the folded state, the toggle switch 541 is in the first trigger state, and the toggle switch 541 is located at one end of the adjustment through hole 511; when the rear support rod is in the position corresponding to the extended state, the toggle switch 541 is in the second trigger state, and the toggle switch 541 is located at the other end of the adjustment through hole 511. The elastic element is configured with a preload force to put the toggle switch 541 in the first trigger state. The elastic element enables the toggle switch 541 to have a self-resetting function, making it more convenient to use. The implementation of the elastic element includes, but is not limited to, a spring 524, a rubber block, etc., and is not the only one described here.

[0057] See Figures 7 to 10To achieve automatic reset of the toggle switch 541, in some embodiments, a toggle lever 521 and a connecting rod 522 are also provided on the rear support rod 520. The connecting rod 522 is perpendicular to the toggle lever 521, and one end is connected to the side of the rear support rod 520 facing the toggle switch 541. The other end of the toggle lever 521 is connected to the connecting rod 522. A receiving groove 523 is formed between the toggle lever 521 and the rear support rod 520. A spring 524 is provided in the receiving groove 523. 24 is connected between the rear support rod 520 and the actuating rod 521, and is configured with a preload force to move the actuating rod 521 away from the rear support rod 520; a spring piece 525 is provided on the side of the actuating rod 521 away from the receiving groove 523, one end of the spring piece 525 is fixed to the connecting rod 522, and the other end is in contact with the actuating rod 521, and the spring piece 525 is configured with a preload force to move the actuating rod 521 closer to the rear support rod 520; wherein, the stiffness of the spring piece 525 is greater than the stiffness of the spring 524. During the transition from the folded state to the extended state, the side of the lever 521 away from the receiving groove 523 first contacts the dial 541. Due to the low stiffness of the spring 524, the dial 541 can easily push the lever 521 to swing towards the rear support rod 520. The lever 521 moves away from the spring piece 525 and compresses the spring 524. After the dial 541 enters the receiving groove 523, it separates from the lever 521. The lever 521 returns to its original position under the action of the spring 524. The rear support rod 520 continues to swing, pushing the dial 541 to switch from the first trigger state to the second trigger state. During the transition from the rear-supported state to the rear-folded state, the toggle switch 541 presses the actuating lever 521 towards the receiving groove 523, causing the actuating lever 521 to swing away from the rear support rod 520. However, the spring piece 525 supports the actuating lever 521. After the toggle switch 541 switches to the first trigger state, the toggle switch 541 can no longer move, and the tilting amplitude of the actuating lever 521 increases until it disengages from the toggle switch 541. After disengaging, the actuating lever 521 resets under the action of the spring piece 525. In this way, there is no need to set an elastic element in the limit switch 540; the toggle switch 541 is reset by external force.

[0058] In some embodiments, the specific implementation of the rear sliding drive device is exemplified as follows:

[0059] 1) The rear sliding drive device is a flexible shaft drive device, in which the flexible shaft can bend and transmit power, and can connect to components that are not in the same direction as the main body of the flexible shaft drive device, so as to drive the target object to move. 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 6 to the rear of the vehicle body, and connect with the first rear slide seat 510. This makes full use of the internal space of the roof 6 and avoids affecting the movement of the first rear slide seat 510. The flexible shaft can also drive the first rear slide seat 510 to move back and forth along the first guide rail 2.

[0060] 2) The rear sliding drive device includes a drive motor, a drive gear connected to the output shaft of the drive motor, and a rack provided on the first guide rail 2 and extending along the long axis of the first guide rail 2. The drive motor is fixed on the first rear slide 510. The drive motor drives the drive gear to rotate, and the drive gear meshes with the rack, thereby realizing the forward and backward movement of the first rear slide 510.

[0061] In some embodiments, the specific implementation of the rear lifting drive device is exemplified as follows:

[0062] 1) The rear lifting drive device is a flexible shaft drive device, in which the flexible shaft can bend and drive, and can connect to components that are not in the same direction as the main body of the flexible shaft drive device to drive the target object to move. The main body of the flexible shaft drive device can be flexibly set inside the tailgate body. For example, the main body of the flexible shaft drive device can be set at the front of the tailgate body, the flexible shaft turns and extends backward along the edge of the tailgate body and connects to the second rear slide 530, making full use of the internal space of the tailgate body.

[0063] 2) The rear lifting drive device includes a drive motor, a drive gear connected to the output shaft of the drive motor, and a rack provided on the second guide rail 4 and extending along the long axis of the second guide rail 4. The drive motor is fixed on the second rear slide 530. The drive motor drives the drive gear to rotate, and the drive gear meshes with the rack, thereby realizing the forward and backward movement of the second rear slide 530.

[0064] In some embodiments, see Figures 4 to 6 The front lifting rod device 3 includes a front support rod 310, a front slide block 320, and a front hinge seat 330. One end of the front support rod 310 is rotatably connected to the front slide block 320, forming a front sliding end. The other end of the front support rod 310 is hinged to the front hinge seat 330, which is mounted on the rear tailgate body 1. The front lifting rod device 3 has a simple overall structure. The front slide block 320 not only meets the sliding cooperation with the first guide rail 2 but also provides stable support for the front support rod 310 and the rear tailgate body 1, resulting in better reliability.

[0065] In some embodiments, see Figure 5 and Figure 6The front support rod 310 has a slider 311 at its end, and the front slide block 320 has a lifting groove 321. The lifting groove 321 is set at an angle to the first guide rail 2 and is inclined upward relative to the first guide rail 2. The slider 311 and the lifting groove 321 are slidably adapted. In the forward-folded state, the slider 311 is at the front end of the lifting groove 321, and in the forward-supported state, the slider 311 is at the rear end of the lifting groove 321. In use, the front slide block 320 is moved forward first, and the slider 311 can slide in the lifting groove 321, and the front support rod 310 is lifted. Combined with the extension of the rear support rod 520, the entire rear door body 1 is lifted. The swing of the front support 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.

[0066] Based on the above embodiments, the rear door switch assembly also includes a front sliding drive device, which is connected to the front slide block 320 to drive the front slide block 320 to move back and forth along the first guide rail 2.

[0067] Based on the lifting groove 321, the following example illustrates the lifting and flipping mechanism of the front support rod 310: With the tailgate body 1 closed, the front sliding drive device moves the front slide block 320 forward along the first guide rail 2. Simultaneously, the rear support rod 520 gradually switches from a folded-back state to a rear-supported state. During the forward movement of the front slide block 320, the tailgate body 1 and the front support rod 310 are restricted by the rear support rod 520, preventing the front support rod 310 from moving forward with the front slide block 320. At this time, the slider 311 moves backward relative to the lifting groove 321, and the position of the slider 311 gradually... The position of the front support rod 310 gradually rises, thereby raising the upper edge of the rear tailgate body 1 so that the upper edge of the rear tailgate body 1 is higher than the roof 6. At the same time, as the rear support rod 520 gradually switches to the rear-supported state, the lower edge of the rear tailgate body 1 also gradually rises until the entire rear tailgate body 1 is higher than the roof 6. Then, the front sliding drive device drives the front sliding block 320 to move forward along the first guide rail 2, and at the same time, the rear sliding drive device drives the first rear sliding block 510 to move forward along the first guide rail 2, so that the entire rear tailgate body 1 moves forward until it moves to the designated position above the roof 6.

[0068] In some embodiments, see Figure 11The front slide block 320 and the first guide rail 2 are distributed in the left-right direction to reduce the vertical dimension, improve the compactness of the structure, and avoid affecting the opening and closing of the tailgate body 1. Based on this, the front slide block 320 has a front drive protrusion 322 on the side facing the first guide rail 2, and the first guide rail 2 has a drive groove 201. The front drive protrusion 322 and the drive groove 201 are slidably adapted to each other. The tailgate opening and closing structure assembly also includes a front sliding drive device, which is a flexible shaft sliding drive device. Its drive end passes through the drive groove 201 and is connected to the front drive protrusion 322. 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. 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 6 to the rear of the vehicle body to connect with the front slide block 320. This makes full use of the internal space of the roof 6 and avoids affecting the movement of the slide block. The flexible shaft can also drive the front slide block 320 to reciprocate along the first guide rail 2. Similarly, the adaptation method between the first rear slide block 510 and the first guide rail 2 is similar to that of the front slide block 320, and will not be described again here.

[0069] The front sliding drive device can also be implemented in other ways. For example, the front sliding drive device includes a drive motor, a drive gear connected to the output shaft of the drive motor, and a rack provided on the first guide rail 2 and extending along the long axis of the first guide rail 2. The drive motor is fixed on the front slide 320. The drive motor drives the drive gear to rotate, and the drive gear meshes with the rack, thereby realizing the forward and backward movement of the front slide 320.

[0070] In some embodiments, a limiting member is provided on the front support rod 310. When the posture of the front support rod 310 corresponds to the front-supported state, the limiting member abuts against the front slide block 320 to limit the upward tilt angle of the tailgate body 1 and improve the reliability of use. Optionally, the limiting member may be implemented in ways including but not limited to a limiting rod provided on the side of the front support rod 310, which extends in the left-right direction.

[0071] Based on the same inventive concept, this application also provides a vehicle including the above-described tailgate switch assembly.

[0072] Compared with the prior art, the vehicle provided in this embodiment, by adopting the above-mentioned tailgate switch architecture assembly, will not obstruct the top of the trunk when the tailgate body 1 is fully opened. The trunk has sufficient openness, and users can place large items more conveniently without having to bend over to pick up or put down items, resulting in a better user experience.

[0073] 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.
