Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a vehicle tailgate, control method, control system, and vehicle. Background Technology

[0002] Currently, some vehicles use a split tailgate opening mechanism, which divides the tailgate into an upper and lower section. External force is used to rotate the upper and lower sections to open the upper section upwards and the lower section downwards. Once both sections are closed, a lock installed between them secures the tailgate.

[0003] Normally, the upper and lower doors must be opened in a strict order. For example, if you want to open the lower door alone, you must first open the upper door to a certain angle before you can open the lower door. This makes the entire opening process of the lower door extremely inconvenient. Summary of the Invention

The word “connection” or “link” is not limited to physical or mechanical connections, but can also include electrical connections, whether direct or indirect.

[0062] This application provides a vehicle tailgate and a vehicle (not shown in the figure), the vehicle including a body and a tailgate. The body is both the part of the vehicle used for loading goods or passengers and the base for installing and connecting other components of the vehicle. The body includes a body frame, and an opening is provided at the rear end of the body frame. The tailgate is installed at the opening at the rear end of the body frame, and the tailgate is also the door of the vehicle's trunk.

[0063] Please refer to Figure 1 , Figure 1 A schematic diagram of a vehicle tailgate 100 as illustrated in an exemplary embodiment of this application is shown.

[0064] The vehicle tailgate 100 includes a first door body 10 and a second door body 20, both of which are movably mounted on the rear end of the vehicle body frame for opening or closing the opening at the rear end of the vehicle body frame. In some embodiments, the first door body 10 and the second door body 20 can be arranged along the height direction (the height direction of the vehicle body), with one being the upper door body of the vehicle tailgate 100 and the other being the lower door body of the vehicle tailgate 100. That is, the upper and lower door bodies open the opening in a top-to-bottom manner, which can avoid occupying the space on both sides of the vehicle body along the width direction. In other embodiments, the first door body 10 and the second door body 20 can also be arranged along the horizontal direction (the width direction of the vehicle body), with one being the left door body of the vehicle tailgate 100 and the other being the right door body of the vehicle tailgate 100. That is, the left and right door bodies open the opening in a left-to-right manner.

[0065] In one embodiment, the first door 10 is rotatably connected to the vehicle frame; for example, the first door 10 can be connected via a pivot 107 (see reference). Figure 2 The first door 10 is connected to the vehicle frame. The first door 10 can rotate around the pivot 107 to be in an open or closed state. The second door 20 is rotatably connected to the vehicle frame. For example, the second door 20 can also be connected to the vehicle frame through the pivot, so that the second door 20 is in an open or closed state, which is more time-saving and labor-saving.

[0066] In another embodiment, the first door 10 may also be slidably connected to the vehicle frame, and the second door 20 may also be slidably connected to the vehicle frame. In some other embodiments, one of the first door 10 and the second door 20 may be rotatably connected to the vehicle frame, and the other may be slidably connected to the vehicle frame.

[0067] One of the first door body 10 and the second door body 20 includes a main door body 101 and a bypass door body 102. The bypass door body 102 is movably disposed on the main door body 101 and can move relative to the main door body 101 from an initial position 103 to a bypass position. The first door body 10 and the second door body 20 are configured to be able to open or close independently when the bypass door body 102 is in the bypass position. The initial position is defined as the bypass door body 102 being aligned front and rear with the main door body 101 when both the first door body 10 and the second door body 20 are closed and the bypass door body 102 is aligned front and rear with the main door body 101. Here, "aligned front and rear" means that along the length of the vehicle body, the front is considered the front and the rear is considered the rear. In the initial position, the bypass door body 102 can partially obscure the opening at the rear end of the vehicle body frame.

[0068] As described above, when the clearance door 102 is in the clearance position, it can be located outside the opening and closing space of the first door 10, allowing the first door 10 to move freely without interference from the second door 20. Furthermore, when the clearance door 102 is in the clearance position, it also allows the second door 20 to move freely without interference from the first door 10. With this configuration, the first door 10 and the second door 20 can be opened and closed independently; that is, the first door 10 can be opened or closed without the second door 20 needing to be opened beforehand, and the second door 20 can be opened or closed without the first door 10 needing to be opened beforehand, making the opening and closing process of the vehicle tailgate 100 more convenient and faster.

[0069] exist Figure 1In the illustrated embodiment, the first door 10 is the lower door of the vehicle tailgate 100, and the second door 20 is the upper door of the vehicle tailgate 100. The lower door is a segmented structure, comprising a main door 101 and a clearance door 102, while the upper door is a single, integral structure. In practical applications, the upper door is opened more frequently than the lower door; therefore, a segmented structure for the lower door is more advantageous, as the upper door has relatively less space to move when opening or closing.

[0070] Of course, in other embodiments, the second door 20, which serves as the lower door, can also be segmented, that is, the second door 20 includes the main door 101 and the bypass door 102. Alternatively, when the first door 10 is the left door of the vehicle tailgate 100 and the second door 20 is the right door of the vehicle tailgate 100, the left door can be configured to include the main door 101 and the bypass door 102, or the right door can be configured to include both the main door 101 and the bypass door 102.

[0071] It should be noted that when the avoidance door 102 is in the initial position 103, both the first door 10 and the second door 20 are closed. The avoidance door 102 is located between the upper door and the main door 101, and is flush with the front and rear, which can enhance the integrity of the vehicle tailgate 100.

[0072] The bypass door 102 is movably disposed on the main door 101, and its specific arrangement is not limited. For example, the bypass door 102 can be rotatably disposed or slidably disposed on the main door 101. In this embodiment, the latter is adopted, that is, the bypass door 102 is slidably disposed on the main door 101. The bypass door 102 can slide relative to the main door 101 from the initial position 103 to the bypass position 111. In this way, compared with rotation, the sliding bypass door 102 can reduce the movement space, making the structure of the vehicle tailgate 100 more compact and saving installation space. For example, when at least one of the first door 10 and the second door 20 needs to be opened, the bypass door 102 is first tilted and slid down in the direction of outward movement of the vehicle, and then each door can be opened or closed independently. In the bypass position, the bypass door 102 protrudes from the rear of the vehicle body.

[0073] Please refer to Figure 2 and Figure 3 , Figure 2 This illustration shows a schematic diagram of the position of the door body 102 when the upper door body is opened, as shown in an exemplary embodiment of this application. Figure 3 This document shows a schematic diagram of a sliding portion and a sliding mating portion as illustrated in an exemplary embodiment of this application.

[0074] In one embodiment, one of the main door body 101 and the bypass door body 102 includes a sliding part 104, and the other includes a sliding engagement part 105. During the process of the bypass door body 102 sliding to the bypass position, the sliding part 104 and the sliding engagement part 105 engage in sliding contact. This arrangement not only enables the bypass door body 102 and the main door body 101 to support each other during relative sliding, but also forms a sliding constraint, thereby ensuring the guiding and smoothness of the sliding.

[0075] In some embodiments, one of the sliding part 104 and the sliding engagement part 105 is a slider, and the other is a slide rail. Of course, the embodiments of the sliding part 104 and the sliding engagement part 105 are not limited to this, as long as they can achieve a sliding engagement between the avoidance door body 102 and the main door body 101.

[0076] In some other embodiments, the bypass door 102 may also be rotatably disposed on the main door 101. For example, the bypass door 102 may rotate relative to the main door 101 from the initial position 103 to the bypass position 110. That is, the bypass door 102 can reach the bypass position 110 after rotating around the rotation axis from the initial position to a certain angle, so that the first door 10 and the second door 20 can be opened or closed independently.

[0077] The avoidance position 110 can have multiple positions. In one embodiment, the avoidance positions include a first avoidance position 109 and a second avoidance position 111 (see reference). Figure 4 The first avoidance position 109 is closer to the initial position than the second avoidance position 111. That is, the first avoidance position 109 of the avoidance door 102 is located before the second avoidance position 111. During the movement of the avoidance door 102, the avoidance door 102 can first reach the first avoidance position 109, at which point the second door 20 can open and close independently; when the avoidance door 102 reaches the second avoidance position 111, the first door 10 can open and close independently. Figure 2 In this vehicle, the left side of the tailgate is the outside, and the right side is the inside. It is understandable that, since the second clearance position 111 is located after the first clearance position 109, when the clearance door 102 reaches the second clearance position 111, both the first door 10 and the second door 20 can open or close simultaneously. Furthermore, "opening or closing independently" means that the first door 10 and the second door 20 do not interfere with each other when opening or closing.

[0078] Please refer to Figure 2 , Figure 4 and Figure 5 , Figure 4 This illustration shows a schematic diagram of the position of the door being avoided when the lower door is opened, as shown in an exemplary embodiment of this application. Figure 5This illustration shows a schematic diagram of the positions of the avoidance door and the main door when the lower door is opened, according to an exemplary embodiment of this application.

[0079] When the second door 20 opens alone, the avoidance door 102 moves to the first avoidance position 109. At this point, the second door 20 can open smoothly without interfering with the first door 10. In other words, when the avoidance door 102 moves to the first avoidance position 109, the first door 10 is outside the movement trajectory of the second door 20, and the second door 20 can open freely.

[0080] refer to Figure 4 and Figure 5 When the first door 10 is opened alone, the avoidance door 102 moves to the second avoidance position 111. This second avoidance position 111 can be the limit position in which the avoidance door 102 can move relative to the main door 101. At this time, the first door 10 can be smoothly rotated and opened without interfering with the second door 20. That is to say, when the avoidance door 102 moves to the second avoidance position 111, the second door 20 is outside the movement trajectory of the first door 10, and the first door 10 can be opened freely.

[0081] It should also be noted that the specific setting of the avoidance position can be appropriately adjusted according to the structural design of the first door 10 and the second door 20 and the spatial design between them. As long as the position of the avoidance door 102 allows the first door 10 and the second door 20 to open or close independently, that is, there is no interference between them, the position can be used as the avoidance position.

[0082] In one embodiment, the main door 101 may include a first locking part, and the bypass door 102 may include a first locking engagement part. For example, the first locking part is disposed on the sliding part 104, and the first locking engagement part is disposed on the sliding engagement part 105. When the bypass door 102 is in the initial position 103, the first locking part and the first locking engagement part are locked. The above structure can reliably lock the bypass door 102 and the main door 101, keeping the bypass door 102 and the main door 101 relatively fixed, and increasing the stability of the positions of the bypass door 102 and the main door 101. The implementation of the first locking part and the first locking engagement part is not limited; for example, it may be a card hole or a claw, or it may be a lock hole and a locking pin, but it is not limited to these. Multiple sets of the first locking part and the first locking engagement part may be provided, and the specific number is not limited, for example, two or more sets.

[0083] In one embodiment, the first door 10 further includes a second locking part, and the vehicle frame includes a second locking engagement part. The second locking part and the second locking engagement part engage to lock the first door 10 when it is in the closed state. This ensures that the first door 10 is reliably connected to the vehicle frame when it is closed. The implementation of the second locking part and the second locking engagement part is not limited, and multiple sets of the second locking part and the second locking engagement part can be provided, with no specific number, such as two or more sets.

[0084] In one embodiment, the second door 20 further includes a third locking part, and the vehicle frame includes a third locking engagement part. The third locking part and the third locking engagement part engage to lock the second door 20 when it is in the closed state. This ensures that the second door 20 is reliably connected to the vehicle frame when it is closed. The implementation of the third locking part and the third locking engagement part is not limited, and multiple sets of the third locking part and the third locking engagement part can be provided, with no specific number, such as two or more sets.

[0085] In one embodiment, the vehicle tailgate 100 further includes a first drive mechanism 106, which includes a drive member and a transmission member. The drive member is connected to the transmission member, and the transmission member is connected to the bypass door body 102 to drive the bypass door body 102 to move relative to the main door body 101. In some embodiments, the drive member and the transmission member can be integrated into an electric strut configured to control the movement of the bypass door body 102 by extension and retraction, which can save installation space. In other embodiments, the drive member and the transmission member can also be separate. The drive member can be a drive motor with an output shaft, and the transmission member can be a lead screw and a gear train, a worm and a worm wheel, or a gear and rack. Of course, the specific structure of the transmission member and the drive member is not limited to these.

[0086] In one embodiment, the vehicle tailgate 100 also includes a sealing structure 108 (see reference). Figure 1 The sealing structure 108 is disposed in the first door body 10 and / or the second door body 20, and is sandwiched between the first door body 10, the second door body 20 and the vehicle frame to ensure the isolation of the space enclosed by the first door body 10, the second door body 20 and the vehicle body from the water environment outside the cabin.

[0087] In one embodiment, the first drive mechanism 106 (reference) Figure 1 It is disposed on the side of the sealing structure 108 facing the first door 10 or the second door 20, that is, between the sealing structure 108 and the first door 10 or the second door 20.

[0088] In one embodiment, a second drive mechanism and a third drive mechanism are further included. The second drive mechanism is connected to the first door 10 and is used to drive the first door 10 to open or close. The third drive mechanism is connected to the second door 20 and is used to drive the second door 20 to open or close. The structures of the second drive mechanism and the third drive mechanism may be substantially the same as or different from the structure of the first drive mechanism 106, which will not be described in detail here.

[0089] Please refer to Figure 6 , Figure 6 A flowchart illustrating a vehicle tailgate control method is shown in an exemplary embodiment of this application.

[0090] This application also provides a method for controlling a vehicle tailgate, the method comprising steps S10 to S30.

[0091] Step S10: Receive a switching instruction for the first door and / or the second door to switch between an open state and a closed state. Here, "switching between an open state and / or a closed state" means that the first door and / or the second door switches from an open state to a closed state, or from a closed state to an open state.

[0092] Step S20: According to the switching command, control the avoidance door to move from the initial position to the avoidance position. The initial position is the position of the avoidance door when both the first and second doors are closed and the avoidance door is aligned with the main door front to back. The meaning of "aligned front to back" is the same as described above and will not be repeated here.

[0093] Step S30: Control the opening or closing of the first door and / or the second door.

[0094] In this method, when the avoidance door 102 is in the avoidance position, it is outside the opening and closing space of the first door 10, allowing the first door 10 to move freely without interference from the second door 20. Furthermore, when the avoidance door 102 is in the avoidance position, it also allows the second door 20 to move freely without interference from the first door 10. With this configuration, the first door 10 and the second door 20 can be opened and closed independently; that is, the first door 10 can be opened or closed without the second door 20 needing to be opened beforehand, and the second door 20 can be opened or closed without the first door 10 needing to be opened beforehand, making the opening and closing process of the vehicle tailgate 100 more convenient and faster.

[0095] The "switching instructions" referred to herein include a first switching instruction for switching the first door and / or the second door from a closed state to an open state, and a second switching instruction for switching the first door and / or the second door from an open state to a closed state. In some embodiments, the first switching instruction for the first door and the first switching instruction for the second door can be executed individually or simultaneously. The second switching instruction for the first door and the second switching instruction for the second door can also be executed individually or simultaneously.

[0096] Upon receiving the switching instruction, the door moves from the initial position to the avoidance position according to the switching instruction. Only when the avoidance door is in the avoidance position will at least one of the first door and / or the second door not interfere with each other during the state switching process, so as to ensure that each can open or close smoothly and independently.

[0097] In one embodiment, controlling the opening or closing of the first door and / or the second door includes:

[0098] Check whether the obstacle avoidance gate is in the avoidance position;

[0099] If the door is in the avoidance position, control the first door and / or the second door to open or close.

[0100] In the above embodiment, a detection step is added to the control method. This detection step can detect the position of the avoidance door to ensure that the first door and / or the second door will not interfere with the avoidance door when they are opened or closed, thus avoiding collisions due to the avoidance door not moving into place.

[0101] In one embodiment, controlling the opening or closing of the first door and / or the second door includes:

[0102] The control of opening or closing the first door and / or the second door includes:

[0103] Check whether the main gate and the bypass gate are locked;

[0104] If the main door and the bypass door are locked, unlock and control the bypass door to move to the bypass position, and control the first door and / or the second door to open or close.

[0105] If the main door and the bypass door are not locked, control the first door and / or the second door to open or close.

[0106] This method can also detect whether the main door and the bypass door are locked. If they are locked, it means the bypass door is not in the bypass position and must be unlocked before moving. The first door and / or the second door can only be opened when the bypass door reaches the bypass position. Conversely, if the main door and the bypass door are not locked, it means the bypass door is in the bypass position, and the first door and / or the second door can be opened directly.

[0107] In one embodiment, the avoidance position may include a first avoidance position and a second avoidance position, wherein the first avoidance position is closer to the initial position than the second avoidance position. That is, when the door moves from the initial position to the avoidance position, it first reaches the first avoidance position and then reaches the second avoidance position.

[0108] The control of opening or closing the first door and / or the second door includes:

[0109] When the bypass door moves to the first bypass position, the system controls the opening or closing of either the first door or the second door that has a bypass door. When the bypass door moves to the second bypass position, the system controls the opening or closing of either the first door or the second door that does not have a bypass door.

[0110] Taking the first door as the lower door and the second door as the upper door as an example, the avoidance positions are set to include a first avoidance position and a second avoidance position, with the first avoidance position preceding the second avoidance position. When controlling the upper door to open or close independently, it is only necessary to move the avoidance door to the first avoidance position for smooth opening or closing. This effectively shortens the movement distance of the avoidance door, thereby reducing time and improving opening and closing efficiency. When controlling the lower door to open or close independently, the avoidance door needs to be moved to the second avoidance position, which provides sufficient space for the lower door to rotate.

[0111] Of course, when the door moves to the second avoidance position, the upper and lower doors can also be controlled to open or close simultaneously. That is, when it is necessary to control the upper and lower doors to open or close at the same time, it is only necessary to control the door to move to the second avoidance position once.

[0112] In one embodiment, when a first switching instruction is received for the first door and / or the second door to switch from the closed state to the open state, the control method further includes:

[0113] Unlocking steps: Control the bypass door to unlock the main door.

[0114] The unlocking step is performed before the door is moved to the avoidance position.

[0115] In the initial position, the bypass door and the main door are locked. The unlocking step can release the lock between the bypass door and the main door. After the lock is released, the bypass door can be moved from the initial position to the bypass position, thereby ensuring that the first door and / or the second door can be opened smoothly.

[0116] In one embodiment, the second gate includes a clearance gate and a main gate, and the control method further includes:

[0117] When the second door switches from the closed state to the open state, the opening duration of the second door in the open state is obtained. If the opening duration is greater than or equal to the first duration threshold, the avoidance door is controlled to reset from the avoidance position to the initial position and the avoidance door and the main door are locked.

[0118] This configuration allows for automatic reset of the avoidance gate and automatic locking of both the avoidance gate and the main gate.

[0119] In one embodiment, when a second switching instruction is received to switch the first door and / or the second door from an open state to a closed state, the control method further includes a locking step: controlling the avoidance door to lock with the main door. The locking step is performed after controlling the avoidance door to reset to its initial position.

[0120] Once the bypass gate has returned to its initial position, it can be locked to keep it relatively fixed to the main gate, thus ensuring the stability of the relative position between the bypass gate and the main gate when closed.

[0121] In one embodiment, the control method further includes: when the first door and the second door are switched to the closed state, controlling the avoidance door to reset from the avoidance position to its initial position. In this way, the avoidance door can fill part of the space, reducing the gap at the joint between the first and second doors after they are closed.

[0122] Please refer to Figure 7 , Figure 7 A flowchart illustrating a control method for opening the upper door body, as shown in an exemplary embodiment of this application, is presented.
