Description

Technical Field

[0001] This application belongs to the technical field of vehicles, and particularly relates to an electrically movable cover and a vehicle. Background Technology

[0002] With fierce competition in the vehicle market, the demand for refinement is increasing. The exposed latches at the door sill after the tailgate is opened do not meet the requirements for high refinement.

[0003] In related technologies, in order to improve aesthetics, a movable cover plate is usually set at the door sill latch to cover the latch. As the usage time increases, scratches will be left on the cover plate, affecting the appearance. Summary of the Invention

[0004] This application aims to at least partially solve the technical problem of scratches easily left on movable covers in related technologies. To this end, this application provides an electrically operated movable cover and a vehicle.

[0005] In a first aspect, an embodiment of this application provides an electrically movable cover, installed on the door sill of a vehicle, the door sill having a latch for connection with a door lock on the rear door of the vehicle and an opening for exposing the latch, characterized in that it includes:

[0006] The cover plate is provided with a clearance hole for the latch to avoid the threshold;

[0007] A pivot is fixedly connected to the cover plate and is used for rotatable connection with the threshold.

[0008] A drive assembly is used to drive the rotating shaft to rotate, so that the rotating shaft drives the cover plate to switch between a first position covering the opening and a second position opening the opening;

[0009] When the cover plate is in the second position with the opening open, the latch extends out of the cover plate through the clearance hole to be exposed to the outside through the opening.

[0010] The cover plate is fixedly connected to the pivot, which is used to rotate with the door sill. During the closing of the tailgate, the drive assembly can drive the pivot to rotate in advance to open the cover plate, allowing the lock to extend out of the cover plate through the clearance hole, thus preventing the cover plate from contacting the door lock and preventing the door lock from scratching the cover plate. During the opening of the tailgate, the drive assembly can drive the pivot to rotate after the tailgate is opened, so that the cover plate covers the opening, preventing the cover plate from contacting the door lock and preventing the door lock from scratching the cover plate.

[0011] In some embodiments, the electrically movable cover further includes a switch and a trigger, one of which is mounted on the pivot and the other is mounted on the threshold.

[0012] In some embodiments, the trigger is mounted on the rotating shaft and has a first trigger portion and a second trigger portion spaced apart, both of which protrude from the outer peripheral surface of the rotating shaft; the switch includes a first switch and a second switch, both of which are mounted on the threshold, the first switch being located on the movement path of the first trigger portion and the second switch being located on the movement path of the second trigger portion.

[0013] In some embodiments, the drive assembly includes a drive member and a transmission member, the drive member being drively connected to the transmission member for driving the transmission member to rotate, and the transmission member being fixedly connected to the rotating shaft.

[0014] In some embodiments, the pivot is disposed on the side of the cover plate away from the clearance hole.

[0015] Secondly, embodiments of this application also provide a vehicle, including a control device, a sill, a tailgate, and an electrically movable cover provided in the first aspect above. The tailgate of the vehicle is provided with a door lock, and the sill is provided with a latch for connecting to the door lock and an opening for exposing the latch. The electrically movable cover is installed on the sill. The control device is electrically connected to the drive assembly to control the drive assembly to drive the rotating shaft to switch the cover between a first position covering the opening and a second position opening the opening.

[0016] In some embodiments, the control device controls the actuation of the drive assembly based on the opening angle of the vehicle tailgate.

[0017] In some embodiments, the vehicle further includes a detector electrically connected to the control device for detecting the opening angle of the vehicle's tailgate.

[0018] In some embodiments, when the opening angle of the back door is less than or equal to a set angle X°, the control device controls the drive assembly to adjust the position of the cover plate so that the cover plate covers or opens the opening.

[0019] In some embodiments, when the distance between the door lock and the cover plate is greater than or equal to a set distance A, the control device controls the drive assembly to operate so that the cover plate covers or opens the opening, and during the operation of the cover plate, the distance between the door lock and the cover plate remains greater than or equal to the set distance A.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0034] In related technologies, a movable cover plate is rotatably connected to the sill and covers the opening under the action of a torsion spring, thus concealing the latch. During the opening of the tailgate, the movable cover plate rotates around its pivot under the action of the torsion spring until it is flush with the larger surface of the sill, thereby covering the opening. During the closing of the tailgate, the door lock pushes the movable cover plate, causing it to overcome the torsion spring's torque and rotate around its pivot to open the opening, exposing the latch, so that the door lock engages with the latch.

[0035] The tailgate opening is achieved by the tailgate lock pushing the cover. The lock contacts the cover, pushing it against the torsion spring and opening the opening. When the door is closed, the cover and lock remain in contact due to the torsion spring. This prolonged contact and friction between the lock and the tailgate causes scratches on both the lock's cover and the tailgate, affecting the appearance.

[0036] The movable cover relies on the torque of the torsion spring to return to its original position and cover the opening. As the usage time increases, the torque of the torsion spring decreases, and the movable cover may fail to completely cover the opening. In addition, when the back door is closed, the cover may collide with the threshold, making abnormal noise.

[0037] Therefore, in related technologies, movable covers are prone to scratches. This application provides an electrically operated movable cover 100 and a vehicle 1000, which can at least partially solve the technical problem of movable covers being prone to scratches in related technologies.

[0038] The electrically movable cover 100 provided in this application embodiment can actively cover or open the opening 220 under the action of the drive component 130, which reduces the wear of the movable cover 110 due to the door lock 310 to a certain extent.

[0039] This application is described below with reference to the accompanying drawings and specific embodiments:

[0040] like Figure 1 As shown, when using the electrically movable cover 100, the electrically movable cover 100 is installed on the sill 200 of the vehicle 1000. The sill 200 is provided with a latch 210 for connecting to a door lock 310 on the tailgate 300 of the vehicle 1000 and an opening 220 for exposing the latch 210.

[0041] like Figure 2 As shown, the electrically movable cover 100 includes a cover 110, a rotating shaft 120, and a drive assembly 130. The cover 110 is provided with a clearance hole 111 for avoiding the latch 210 of the threshold 200. The rotating shaft 120 is fixedly connected to the cover 110 and is used to rotately connect with the threshold 200. The drive assembly 130 is used to drive the rotating shaft 120 to rotate, so that the rotating shaft 120 drives the cover 110 to switch between a first position covering the opening 220 and a second position opening the opening 220. When the cover 110 is in the second position opening the opening 220, the latch 210 extends out of the cover 110 through the clearance hole 111 and is exposed to the outside through the opening 220.

[0042] The clearance hole 111 is used to avoid the latch 210 on the threshold 200. The latch 210 can extend out of the cover plate 110 through the clearance hole 111 and be exposed in the opening 220, so that the latch 210 can be locked with the door lock 310.

[0043] The shape and size of the clearance hole 111 are related to the shape and size of the latch 210. The position of the clearance hole 111 on the cover plate 110 is related to the position of the latch 210. This application does not limit the position of the clearance hole 111, and users can make adaptive designs according to specific circumstances.

[0044] The clearance hole 111 can be like Figure 2 As shown, an open hole with an opening is provided on the side of the cover plate 110 away from the rotating shaft 120; the clearance hole 111 can also be provided in the middle area of ​​the cover plate 110 to form a closed hole without an opening.

[0045] For example Figure 2 As shown, the clearance hole 111 is designed as an open hole, which allows the clearance hole 111 to only avoid a part of the latch 210. This design reduces the restriction of the size of the latch 210 on the size of the clearance hole 111 to a certain extent, which helps to reduce the size of the clearance hole 111, thereby reducing the size of the cover plate 110 and helping to achieve the miniaturization design of the cover plate 110.

[0046] The rotating shaft 120 is fixedly connected to the cover plate 110. When in use, the rotating shaft 120 and the threshold 200 are rotatably connected. When the driving component 130 drives the rotating shaft 120 to rotate, the cover plate 110 will rotate because it is fixed on the rotating shaft 120.

[0047] Under the action of the drive assembly 130, the drive assembly 130 can at least stop the cover plate 110 in the first position covering the opening 220 and the second position opening the opening 220.

[0048] When the cover plate 110 is rotated to the first position, it covers the opening 220 and conceals the latch 210, making it invisible to the naked eye and thus satisfying the requirements for the refinement and aesthetics of the vehicle 1000. When the cover plate 110 is rotated to the second position, it does not conceal the opening 220, meaning the opening 220 is open. When the opening 220 is open, the latch 210 extends out of the cover plate 110 through the clearance hole 111. At this time, the latch 210 is exposed through the opening 220, and the door lock 310 of the tailgate 300 can then be connected to the latch 210.

[0049] The function of the drive assembly 130 is to drive the rotating shaft 120 to rotate. Its structure is diverse. It can be a single motor 1311, a system composed of motor 1311 combined with gears and other transmission components, or a system composed of a power cylinder (electric cylinder, pneumatic cylinder, hydraulic cylinder, etc.) combined with gears, racks and pinions and other transmission components. No limitation is made in this application.

[0050] After the electric movable cover 100 of this application is designed according to the above structure, the cover 110 actively covers or opens the opening 220 under the action of the drive component 130. The cover 110 can be rotated to the second position before the door lock 310 contacts the cover 110, so as not to contact the cover 110. The cover 110 can also be rotated to the first position after the back door 300 is opened, so as not to contact the cover 110. This avoids the door lock 310 from contacting the cover 110, and there will be no scratches between the door lock 310 and the cover 110.

[0051] With this design, since the cover plate 110 actively opens the opening 220 under the action of the drive component 130, the cover plate 110 does not contact the door lock 310 at the moment of closing the door. The door lock 310 will not collide with the cover plate 110, and the cover plate 110 will not collide with the threshold 200 due to the force of the door lock 310. During the closing process, no collision noise will be emitted from the cover plate 110, which brings a better user experience.

[0052] In addition, since this application drives the cover plate 110 to rotate via the drive assembly 130, it helps to keep the cover plate 110 continuously and accurately in the first and second positions, and the service life of the electrically movable cover plate 100 is longer.

[0053] When the cover plate 110 rotates from the first position to the second position, the cover plate 110 stops rotating and remains in the second position; when the cover plate 110 rotates from the second position to the first position, the cover plate 110 stops rotating and remains in the first position.

[0054] like Figure 3 As shown, in some embodiments, the drive assembly 130 includes a motor 1311. A detector detects the number of rotations of the output shaft of the motor 1311. By detecting the number of rotations of the motor 1311, the position of the cover plate 110 is indirectly determined. When the cover plate 110 is in a first position or a second position, the motor 1311 stops working, thereby allowing the cover plate 110 to remain in the first position or the second position. The detector can be an absolute position encoder. The installation location and detection principle of the absolute position encoder are known to those skilled in the art and will not be described in detail here.

[0055] In some embodiments, the electrically movable cover 100 also includes a position sensor to directly detect the position of the cover 110. When the cover 110 is in the first position or the second position, the motor 1311 stops working, thereby enabling the cover 110 to remain in the first position or the second position.

[0056] like Figure 2As shown, in some embodiments, the electrically movable cover 100 also includes a switch 140 and a trigger 150, one of which is mounted on the pivot 120 and the other is for mounting on the threshold 200.

[0057] Alternatively, switch 140 can be mounted on shaft 120, and trigger 150 can be mounted on threshold 200; or switch 140 can be mounted on threshold 200, and trigger 150 can be mounted on shaft 120. When drive assembly 130 drives shaft 120 to rotate, since one of trigger 150 and switch 140 is mounted on shaft 120 and the other on threshold 200, switch 140 and trigger 150 will move relative to each other, allowing trigger 150 to contact switch 140 and thus trigger switch 140.

[0058] It should be noted that switch 140 can be electrically connected to drive assembly 130, and of course, switch 140 can also be electrically connected to the control device of vehicle 1000. When switch 140 is triggered by trigger 150, it indicates that cover 110 has reached the first position or the second position. Switch 140 will send a stop signal to drive assembly 130 or control device, causing drive assembly 130 to stop operating and thus remain in the first position or the second position.

[0059] Specifically, when the cover plate 110 reaches the first position, the trigger 150 will trigger the switch 140, causing the drive assembly 130 to stop working. When the cover plate 110 reaches the second position, the trigger 150 will also trigger the switch 140, causing the drive assembly 130 to stop working.

[0060] In some embodiments, the switch 140 has two trigger points, namely a first trigger point and a second trigger point. When the cover plate 110 reaches the first position, the trigger 150 contacts the first trigger point, and when the cover plate 110 reaches the second position, the trigger 150 contacts the second trigger point.

[0061] The structure of the trigger 150 is varied and is not limited here. The function of the trigger 150 is to contact the switch 140, trigger the switch 140, and enable the switch to send a stop signal.

[0062] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the trigger 150 is mounted on the rotating shaft 120 and has a first trigger portion 151 and a second trigger portion 152 spaced apart. Both the first trigger portion 151 and the second trigger portion 152 protrude from the outer peripheral surface of the rotating shaft 120. The switch 140 includes a first switch 141 and a second switch 142. Both the first switch 141 and the second switch 142 are mounted on the threshold 200. The first switch 141 is located on the movement path of the first trigger portion 151, and the second switch 142 is located on the movement path of the second trigger portion 152.

[0063] When the shaft 120 rotates, the trigger 150 rotates with the shaft 120, while the switch 140 remains stationary. Since both the first trigger part 151 and the second trigger part 152 protrude from the outer peripheral surface of the shaft 120, and the first switch 141 is located on the movement path of the first trigger part 151 and the second switch 142 is located on the movement path of the second trigger part 152, the first trigger part 151 can contact the first switch 141 to trigger the first switch 141, and the second trigger part 152 can contact the second switch 142 to trigger the second switch 142.

[0064] Specifically, such as Figure 6 As shown, when the cover plate 110 is rotated to the first position, the first trigger part 151 contacts the first switch 141, triggering the first switch 141. The first switch 141 sends a stop signal to the control device or drive assembly 130, so that the drive assembly 130 stops working and the cover plate 110 remains in the first position.

[0065] like Figure 7 As shown, when the cover plate 110 is rotated to the second position, the second trigger part 152 contacts the second switch 142, triggering the second switch 142. The second switch 142 sends a stop signal to the control device or drive assembly 130, so that the drive assembly 130 stops working and the cover plate 110 remains in the second position.

[0066] Specifically, as the cover plate 110 rotates from the first position to the second position, the trigger 150 rotates with the rotating shaft 120. The first trigger part 151 gradually moves away from the first switch 141, and the second trigger part 152 gradually moves closer to the second switch 142 until the second trigger part 152 contacts the second switch 142. Similarly, as the cover plate 110 rotates from the second position to the first position, the second trigger part 152 gradually moves away from the second switch 142, and the first trigger part 151 gradually moves closer to the first switch 141 until the first trigger part 151 contacts the first switch 141.

[0067] In some embodiments, switch 140 is a contact switch 140, but it can also be of other types. The structure of contact switch 140 is diverse and is known to those skilled in the art. Based on the above content, those skilled in the art know the specific design of contact switch 140 and its electrical connection structure, etc., and will not be described in detail here.

[0068] In some embodiments, the angle between the first line connecting the first trigger part 151 and the first line connecting the second trigger part 152 and the second line connecting the second trigger part 152 and the second line connecting the second trigger part 152 and the second line connecting the second trigger part 152 and the second line connecting the second trigger part 152 is equal to the angle between the first position and the second position of the cover plate 110, so as to ensure that when the cover plate 110 is in the first position, the first trigger part 151 triggers the first switch 141, and when the cover plate 110 is in the second position, the second trigger part 152 triggers the second switch 142.

[0069] like Figure 2 and Figure 3 As shown, in some embodiments, the drive assembly 130 includes a drive member 131 and a transmission member 132. The drive member 131 is connected to the transmission member 132 for driving the transmission member 132 to rotate. The transmission member 132 is fixedly connected to the rotating shaft 120.

[0070] The transmission component 132 is fixedly connected to the rotating shaft 120. The driving component 131 is connected to the transmission component 132. The driving component 131 drives the transmission component 132 to rotate, which in turn drives the rotating shaft 120 to rotate, thereby allowing the cover plate 110 to switch between the first position and the second position.

[0071] like Figure 3 As shown, in some embodiments, the drive component 131 includes a motor 1311 and a gear set 1312. The output shaft of the motor 1311 is connected to the gear set 1312 for transmission, driving the gear set 1312 to rotate. The transmission component 132 is fixedly installed at one end of the rotating shaft 120. The transmission component 132 has a meshing portion that meshes with the output component in the gear set 1312. The rotation of the motor 1311 drives the gear set 1312 to rotate, which in turn drives the transmission component 132 to rotate, thereby causing the rotating shaft 120 to rotate.

[0072] In these embodiments, the rotation direction of the cover plate 110 is controlled by controlling the rotation direction of the motor 1311. For example, when the motor 1311 rotates forward, the motor 1311 drives the cover plate 110 to rotate from the second position to the first position until the first triggering part 151 triggers the first switch 141; when the motor 1311 rotates in reverse, the motor 1311 drives the cover plate 110 to rotate from the first position to the second position until the second triggering part 152 triggers the second switch 142.

[0073] like Figure 2As shown, in some embodiments, the length of the rotating shaft 120 is the same as the length of the cover plate 110, and both ends of the rotating shaft 120 extend out of the cover plate 110. The trigger 150 and the transmission member 132 are located at the two ends of the rotating shaft 120, respectively.

[0074] The rotating shaft 120 can be located in the middle area of ​​the cover plate 110, or it can be located on one side of the cover plate 110. For example... Figure 2 As shown, in some embodiments, the pivot 120 is located on the side of the cover plate 110 away from the clearance hole 111.

[0075] The rotating shaft 120 is positioned away from the side of the clearance hole 111, so that the rotation speed of the clearance hole 111 area is greater than the speed of the side closer to the rotating shaft 120, so that when the cover plate 110 rotates from the second position to the first position, the cover plate 110 can quickly block the latch 210.

[0076] like Figure 1 As shown, based on the same inventive concept, this application also provides a vehicle 1000, including a control device, a sill 200, a tailgate 300, and the aforementioned electrically movable cover 100. The tailgate 300 is provided with a door lock 310, and the sill 200 is provided with a latch 210 for connecting to the door lock 310 and an opening 220 for exposing the latch 210. The electrically movable cover 100 is installed on the sill 200. The control device is electrically connected to a drive assembly 130 to control the drive assembly 130 to drive the rotating shaft 120 to switch the cover 110 between a first position covering the opening 220 and a second position opening the opening 220.

[0077] The electrically movable cover 100 is installed on the threshold 200. Specifically, the drive assembly 130 of the electrically movable cover 100 is installed on the threshold 200, and the rotating shaft 120 of the electrically movable cover 100 is rotatably connected to the threshold 200.

[0078] It should be noted that vehicle 1000 also includes body 400, sill 200 and tailgate 300 are all installed on body 400.

[0079] In some implementations, the upper side of the tailgate 300 is rotatably connected to the vehicle body 400, allowing the tailgate 300 to rotate to open or close the storage compartment. With technological advancements and the demands of different usage scenarios, in some embodiments, the tailgate 300 is slidably connected to the vehicle body 400 along its height. Sliding the tailgate 300 upwards opens the storage compartment, while sliding it downwards engages the door lock 310 with the latch 210, thereby closing the storage compartment and preventing items from falling out.

[0080] The shape and size of the rear door 300 are not limited in this application. The door lock 310 is installed on the rear door 300. When the door lock 310 and the latch 210 on the sill 200 are locked, the rear door 300 of the vehicle 1000 is in the closed state. When the door lock 310 and the latch 210 on the sill 200 are separated, the rear door 300 can be moved to open the storage cavity and take out the goods in the storage cavity.

[0081] The structures of the door lock 310 and the latch 210 are varied and known to those skilled in the art, and are not limited herein.

[0082] The control device is electrically connected to the drive assembly 130 and controls the operation of the drive assembly 130. Of course, the control device can also be electrically connected to other components on the vehicle 1000 to control the working status of other components.

[0083] The control device controls the drive assembly 130 to drive the rotating shaft 120, causing the cover plate 110 to switch between a position covering the opening 220 and a position opening the opening 220. Specifically, when the door lock 310 is locked with the latch 210, the control device controls the drive assembly 130 to drive the rotating shaft 120, causing the cover plate 110 to rotate to the second position, thereby opening the opening 220 and exposing the latch 210. When the door lock 310 is disengaged from the latch 210, the control device controls the drive assembly 130 to drive the rotating shaft 120, causing the cover plate 110 to rotate to the first position, thereby covering the opening 220 and concealing the latch 210.

[0084] The control device can adjust the operation of the drive component 130 according to the position of the tailgate 300. The position can be the position of the tailgate 300 relative to the ground, or the position of the tailgate 300 relative to the threshold 200, etc.

[0085] In some embodiments, the control device controls the actuation of the drive assembly 130 based on the opening angle of the tailgate 300.

[0086] In these embodiments, the tailgate 300 is rotatably connected to the vehicle body 400.

[0087] like Figure 8 As shown, the opening angle can be the angle between the first line and the second line. The first line refers to the line connecting the end of the rear door 300 away from the rear door pivot to the rear door pivot, and the second line refers to the line connecting the threshold 200 to the rear door pivot.

[0088] Specifically, when the control device detects that the opening angle of the rear door 300 decreases, that is, when the rear door 300 gradually approaches the threshold 200 and the rear door 300 is closed, the control device will control the drive assembly 130 to drive the rotating shaft 120 to rotate, causing the cover plate 110 to rotate to the second position to open the opening 220, so that the door lock 310 can engage with the latch 210. When the control device detects that the opening angle of the rear door 300 increases, that is, when the rear door 300 gradually moves away from the threshold 200 and the rear door 300 is open, the control device will control the drive assembly 130 to drive the rotating shaft 120 to rotate, causing the cover plate 110 to rotate to the first position, covering the opening 220 and obscuring the latch 210.

[0089] The control device automatically adjusts the position of the cover 110 according to the opening angle of the tailgate 300, realizing an intelligent design that can bring a better user experience. In addition, the opening angle of the tailgate 300 can accurately reflect the relative position of the tailgate 300 to the threshold 200, thus providing a more accurate reference for the control device to control the movement of the drive component 130 and reducing the probability of misjudgment.

[0090] In some embodiments, the vehicle 1000 also includes an opening angle detector electrically connected to the control device for detecting the opening angle of the tailgate 300.

[0091] The opening angle detector can be a distance sensor, an absolute position encoder, an angle sensor, etc., and is not limited in this application. In addition, the principle of the opening angle detector to detect the opening angle is diverse. For example, the detector can detect the rotation angle of the back door 300 to obtain the opening angle of the back door 300, or it can detect the distance between the back door 300 and the threshold 200, and then calculate the opening angle of the back door 300 through a formula (such as the inverse trigonometric function formula, etc.), etc., and is not limited in this application.

[0092] The opening angle detector is electrically connected to the control device and transmits the opening angle it detects to the control device. The control device controls the drive component 130 to operate based on the opening angle information transmitted by the opening angle detector.

[0093] In order to provide a better user experience, in some embodiments, when the opening angle of the back door 300 is less than or equal to the set angle X°, the control device controls the drive component 130 to adjust the position of the cover plate 110 so that the cover plate 110 covers or opens the opening 220.

[0094] When the opening angle of the back door 300 is less than or equal to the set angle X, people standing behind the back door 300 will have their view obstructed, and they will not be able to see the opening 220 on the threshold 200. The cover 110 covers or opens the opening 220 when the opening angle of the back door 300 is less than or equal to the set angle X°, ensuring that the cover 110 always covers the opening 220 within the visible range, providing a better user experience.

[0095] Specifically, during the opening of the tailgate 300, the control device controls the drive assembly 130 to adjust the position of the cover plate 110 when the opening angle of the tailgate 300 is less than or equal to a set angle X°, so that the cover plate 110 covers the opening 220. The cover plate 110 covers the opening 220 when the tailgate 300 is at or below the set angle X°, meaning the cover plate 110 covers the opening 220 before the tailgate 300 rotates to a position where it does not obstruct people's view of the opening 220, ensuring that the cover plate 110 covers the opening 220 within people's field of vision during the opening of the tailgate 300.

[0096] Specifically, during the closing process of the tailgate 300, the control device controls the drive assembly 130 to adjust the position of the cover plate 110 when the opening angle of the tailgate 300 is less than or equal to a set angle X, so that the cover plate 110 opens the opening 220. The cover plate 110 opens the opening 220 when the tailgate 300 is less than or equal to the set angle X°, that is, the cover plate 110 opens the opening 220 after the tailgate 300 is rotated to the point where it blocks people's view of the opening 220, so that during the closing process of the tailgate 300, the cover plate 110 covers the opening 220 within people's field of vision.

[0097] The setting angle X° is related to people's height, the rotation radius of the back door, etc. Users can make adaptive designs according to specific circumstances, and the specific value is not limited in this application.

[0098] The angle X can be calculated using trigonometric functions, and the specific formula is as follows: Where H is the height of people's eyes from the ground when they are standing, h is the height of the threshold 200 from the ground, D is the horizontal distance between people's eyes and the threshold cover when they are standing, and R is the rotation radius of the back door 300.

[0099] H can be obtained by calculating the average height of the eyes of the shorter people in a group from the ground. D can be obtained by calculating the average horizontal distance between the eyes of the shorter people in a group and the threshold cover.

[0100] In some embodiments, the average height of the eyes of women in the bottom 5% of a certain number of female populations when standing is taken as the value of H, and the average horizontal distance between the eyes of women in the bottom 5% of a certain number of female populations when standing is taken as the value of D.

[0101] In some embodiments, when the distance between the door lock 310 and the cover plate 110 is greater than or equal to a set distance A, the control device controls the drive assembly 130 to operate so that the cover plate 110 covers or opens the opening 220, and the distance between the door lock 310 and the cover plate 110 remains greater than or equal to the set distance A during the operation of the cover plate 110.

[0102] In other words, during the opening of the back door 300, the control device controls the drive assembly 130 to adjust the position of the cover plate 110 when the distance between the door lock 310 and the cover plate 110 is greater than or equal to A, so that the cover plate 110 moves from the second position to the first position to cover the opening 220. During the process of the cover plate 110 rotating from the second position to the first position, the distance between the cover plate 110 and the back door 300 must always be greater than or equal to A.

[0103] In other words, during the closing process of the tailgate 300, the control device controls the drive assembly 130 to operate when the distance between the tailgate 300 and the cover plate 110 is greater than or equal to A, and adjusts the position of the cover plate 110 so that the cover plate 110 moves from the first position to the second position to open the opening 220. During the process of the cover plate 110 rotating from the first position to the second position, the distance between the cover plate 110 and the tailgate 300 must always be greater than or equal to A.

[0104] During the opening of the rear door 300, the drive assembly 130 drives the cover plate 110 to rotate only when the distance between the door lock 310 and the cover plate 110 is greater than or equal to A. Furthermore, during the rotation of the cover plate 110, the distance between the cover plate 110 and the door lock 310 is maintained at a level greater than or equal to A, ensuring that the distance between the cover plate 110 and the rear door 300 remains greater than or equal to A throughout the opening process. During the closing of the rear door 300, the drive assembly 130 drives the cover plate 110 to rotate before the distance between the door lock 310 and the cover plate 110 becomes less than or equal to A. Again, during the rotation of the cover plate 110, the distance between the cover plate 110 and the door lock 310 is maintained at a level greater than or equal to A, ensuring that the distance between the cover plate 110 and the rear door 300 remains greater than or equal to A throughout the closing process. In this way, during the process of closing or opening the back door 300, there is always a safe distance of greater than or equal to A between the cover plate 110 and the door lock 310 of the back door 300, ensuring that the cover plate 110 and the door lock 310 do not come into contact, thus avoiding the situation where the cover plate 110 and the door lock 310 come into contact with each other and cause scratches.

[0105] The distance between the cover plate 110 and the door lock 310 can be measured directly by tools such as a distance sensor, or it can be estimated by combining the opening angle of the back door 300 with a formula. This application does not limit the distance.

[0106] In some embodiments, a drive device is installed on the tailgate 300 to drive the tailgate 300 to open or close. The drive device may be an electric strut.

[0107] In these embodiments, when the control device receives an instruction to open the back door 300, the control device controls the door lock 310 and the latch 210 to unlock, controls the drive device to operate, drives the back door 300 to rotate around the pivot 120 to open the storage cavity, and also controls the drive assembly 130 to drive the cover plate 110 to rotate from the second position to the first position to cover the opening 220.

[0108] In these embodiments, when the control device receives a command to close the back door 300, the control device drives the drive device to rotate the back door 300 around the pivot 120 to close the storage cavity. It also controls the drive assembly 130 to drive the cover plate 110 to rotate from the first position to the second position to open the opening 220, and controls the door lock 310 and the latch 210 to lock together.
