Description

Technical Field

[0001] This application relates to the field of intelligent vehicles, and more specifically, to a trunk lid assembly and a vehicle. Background Technology

[0002] With the diversification of vehicle functions, vehicles have gradually transformed from traditional means of transportation into mobile carriers adaptable to multiple scenarios, and their application scope is gradually extending to outdoor leisure fields (such as camping, fishing, and other outdoor activities). In these outdoor scenarios, users' needs for vehicles are no longer limited to their driving function, but will generate other usage needs; for example, when the vehicle is parked, users may have the need to sit on the tailgate sill.

[0003] Currently, vehicles often have a multi-tiered, stepped structure near the tailgate sill, consisting of the trunk lid, tailgate sill, and rear bumper. This structure results in a poor passenger experience when sitting on the tailgate sill. Improving the passenger experience in this situation is a problem that needs to be addressed. Summary of the Invention

[0004] This application provides a trunk lid assembly and a vehicle, wherein the lid structure in the trunk lid assembly can extend rearward from the vehicle's trunk, and after extending rearward, it can overcome the multi-step structure originally formed at the tailgate sill of the vehicle, thereby improving the user's riding experience when sitting in the rear of the trunk.

[0005] In a first aspect, a trunk lid assembly is provided. This trunk lid assembly is used in the trunk of a vehicle. The trunk lid assembly includes a lid structure, a slider, and a guide rail. The guide rail is fixedly disposed along the length direction of the vehicle, has a component along the height direction of the vehicle, and its front end is lower than its rear end. The slider is disposed on the guide rail and is movable along the guide rail. The lid structure is rotatably connected to the slider, and the axis of rotation of the lid structure has a component along the width direction of the vehicle.

[0006] In this application, the guide rail arranged along the length of the vehicle forms a certain angle with the length of the vehicle in a "lower front, higher rear" manner. When the slider moves from front to back in the guide rail, the cover plate structure connected to the slider will move backward with the slider, so that the cover plate structure extends backward from the trunk of the vehicle. Moreover, during the process of the cover plate structure extending backward, its position in the height direction of the vehicle will gradually rise, so that the cover plate structure can be higher than the tailgate sill after extending backward, thereby overcoming the multi-step structure originally formed at the tailgate sill of the vehicle, thus improving the user's riding experience.

[0007] In some implementations, the trunk lid assembly can have a first mode and a second mode. In the first mode, the entire lid structure can be positioned in front of the vehicle's tailgate sill. In the second mode, a portion of the lid structure can be positioned in front of the tailgate sill, and at least a portion of the lid structure can be positioned above and abut against the tailgate sill.

[0008] In this application, in the first mode, the cover structure is positioned in front of the tailgate sill, allowing the user to place items from the trunk onto the cover structure; in this mode, the trunk cover assembly functions as a traditional trunk cover. In the second mode, even if the tailgate sill and rear bumper still form a stepped structure, this stepped structure will be located below the cover structure. When the user needs to sit in the rear of the trunk, the vehicle will no longer directly support the user through the stepped structure, but rather through the cover structure above the tailgate sill. Since the top of the cover structure is relatively flat, this improves the user's resting experience.

[0009] In some implementations, in the first mode, the cover plate structure can be lower than the tailgate threshold.

[0010] In this application, in the first mode, the tailgate sill, which is higher than the cover plate structure, can restrict the movement of goods on the cover plate structure to prevent them from directly hitting the tailgate when they move backward, thereby reducing the probability of the tailgate making knocking noises or being damaged due to the impact of goods.

[0011] In some implementations, the trunk lid assembly may also include a support block connected to the lid structure. This support block may be located at the bottom of the lid structure and near its rear end; the main body of the support block may be made of foam material. In a second configuration, the support block may be positioned above and abut against the rear bumper.

[0012] In this application, the support block is located below the cover plate structure near the rear end, and in the second mode, the support block is positioned above the rear bumper and can abut against it. Therefore, in the second mode, the rear bumper can support the rear end of the cover plate structure via the support block, preventing the cover plate structure from forming a long "cantilever beam" with the tailgate sill at the rear end, thus improving the load-bearing capacity of the cover plate structure in the second mode. Furthermore, since the main body of the support block is made of foam material, surface damage to the rear bumper caused by contact with the support block can be avoided.

[0013] In some implementations, the cover plate structure may include a first mating part, which can be used to abut against the load-bearing structure in a second mode. The load-bearing structure may be located on the vehicle body and between the guide rail and the tailgate sill.

[0014] In the second mode, the slider-cover structure-tailgate sill will form a "simply supported beam". In this application, in the second mode, the first mating part can abut against the load-bearing structure installed on the vehicle body, so that the cover structure can be supported by the load-bearing structure. For the "simply supported beam" formed by the slider-cover structure-tailgate sill, in this way, the load-bearing structure will provide additional support to the cover structure between the slider and the tailgate sill through the first mating part, thereby improving the stress on the cover structure, which is beneficial to reducing the deformation of the cover structure in the second mode and improving the load-bearing capacity of the trunk cover assembly.

[0015] In some implementations, the cover plate structure may also include a second mating part. This second mating part can be positioned above and abutting against the tailgate sill in the second mode. In the vehicle's height direction, the first mating part may be lower than the second mating part.

[0016] If the first and second mating parts are at the same height in the vehicle's vertical direction, the top of the load-bearing structure needs to be flush with the tailgate sill. This design necessitates the installation of a corresponding clearance structure on the cover plate structure to prevent interference between the cover plate structure and the load-bearing structure in the first mode. The presence of this clearance structure may expose the load-bearing structure to the user's view, thus affecting the shape and aesthetics of the trunk.

[0017] In this application, by placing the first mating part at a position lower than the second mating part, it is not necessary to set an avoidance structure corresponding to the load-bearing structure on the cover plate structure, which is beneficial to improving the aesthetics of the vehicle's shape.

[0018] In some implementations, the load-bearing structure may have a lock hole, and the first mating part may include a locking pin that mates with the lock hole. When the locking pin is in the lock hole, it can be used to restrict the movement of the cover plate structure in at least one of the length and height directions of the vehicle.

[0019] In this application, by providing a lock hole on the load-bearing structure and providing a lock pin that engages with the lock hole in the first mating part, the movement of the cover plate structure can be restricted by the engagement of the lock pin and the lock hole, thereby improving the stability of the cover plate structure in the second mode and preventing the user from falling off the cover plate structure due to its instability.

[0020] In some implementations, the trunk lid assembly may also include an operating handle disposed on the lid structure. The operating handle is drively connected to the lock cylinder via a first transmission assembly. The operating handle can be used to drive the lock cylinder to extend or retract within the keyhole to achieve locking and unlocking.

[0021] In some implementations, the first transmission assembly may include: a first locking rod connected to the operating handle, and a second locking rod connected to the locking pin. The operating handle can drive the first locking rod to rotate, thereby causing the second locking rod and the locking pin to rotate about the rotation axis of the second locking rod, so as to realize the extension and retraction of the locking pin in the keyhole.

[0022] In some implementations, the trunk lid assembly may further include a first motor, a second motor, and a second transmission assembly. The first motor may be fixedly mounted on the vehicle and connected to the slider via the second transmission assembly; the first motor may be used to drive the slider to move along a guide rail. The second motor may be used to drive the lid structure to rotate relative to the slider about a rotation axis.

[0023] In this application, by setting a first motor and a second motor, the luggage compartment cover assembly can be automatically switched between different modes, thereby saving the user the operation of switching modes of the luggage compartment cover assembly.

[0024] In some implementations, the second transmission component may include a lead screw; the lead screw may be driven to the first motor, and the slider may be driven to the lead screw.

[0025] In this application, a lead screw motor is used to realize the movement of the slider within the guide rail, which can save the space required for the transmission components and also achieve high-precision control of the slider movement.

[0026] In some implementations, the second motor can be fixedly mounted on the cover plate structure and connected to the slider via a third transmission assembly. The third transmission assembly may include a first gear connected to the second motor and a second gear connected to the slider. The first gear and the second gear can be connected in a transmission manner.

[0027] In this application, the second motor is mounted on the cover plate structure and the second motor and the slider are connected by a gear set transmission, which helps to save the space for the transmission components and also helps to reduce friction noise caused by improper drive design.

[0028] Secondly, a control method is provided. The method includes: acquiring control information, the control information indicating a target mode for the trunk lid assembly, the target mode including a first mode or a second mode; and controlling the trunk lid assembly to switch to the target mode according to the control information.

[0029] For a description of the luggage compartment cover assembly, the first mode, and the second mode, please refer to the relevant records in the first aspect above.

[0030] In some implementations, the trunk lid assembly can be in a first mode before mode switching, and the control information can indicate that the target mode is a second mode. Controlling the trunk lid assembly to switch to the target mode according to the control information can include: controlling the lid structure to rotate around the rotation axis in a first direction to a first posture; controlling the slider to move the lid structure backward along the guide rail while the lid structure is in the first posture; and controlling the lid structure to rotate around the rotation axis in the opposite direction of the first direction when the slider reaches a first preset position. In the first posture, the entire lid structure can be positioned in front of the tailgate sill, and the bottom of the rear end of the lid structure can be higher than the tailgate sill; when the slider reaches the first preset position, a portion of the lid structure is above the tailgate sill.

[0031] In this application, by controlling the rotation of the cover plate structure before the slider moves backward so that the bottom of its rear end is higher than the tailgate sill, interference between the cover plate structure and the tailgate sill can be avoided during the slider's backward movement. After part of the cover plate structure is above the tailgate sill, controlling the cover plate structure to rotate towards the cover plate structure can prevent the cover plate structure from failing to be above the tailgate sill after rotating in the opposite direction of the first direction.

[0032] In some implementations, the first preset position may include the position of the slider in the second mode.

[0033] In this application, after the slider moves backward to the position corresponding to the second mode, the cover plate structure is then controlled to rotate in the opposite direction of the first direction. This helps to reduce the requirement for control precision and also helps to avoid unexpected interference under lower control precision.

[0034] In some implementations, the trunk lid assembly can be in a second mode before mode switching, and the control information can indicate that the target mode is the first mode. Controlling the trunk lid assembly to switch to the target mode according to the control information can include: controlling the lid structure to rotate around its rotation axis in a first direction to a second posture; controlling a slider to move the lid structure forward along a guide rail while the lid structure is in the second posture; and controlling the lid structure to rotate around its rotation axis in the opposite direction of the first direction when the slider reaches a second preset position. In the second posture, the lid structure is above the tailgate sill but not in contact with it.

[0035] In this application, before the slider moves forward, the cover plate structure is rotated to prevent it from contacting the tailgate sill, thus avoiding frictional noise caused by the cover plate structure contacting the tailgate sill when the slider moves forward.

[0036] In some implementations, the second preset position may include the position of the slider in the first mode.

[0037] In this application, after the slider moves forward to the position corresponding to the first mode, the cover plate structure is then controlled to rotate in the opposite direction of the first direction. This helps to reduce the requirement for control precision and also helps to avoid unexpected interference under lower control precision.

[0038] In some implementations, the movement of the slider along the guide rail and the rotation of the cover plate structure around the rotation axis can occur simultaneously during the first time period.

[0039] In this application, during the first time period of the mode switching process, the movement of the slider is synchronized with the rotation of the cover plate structure, which can shorten the overall switching time.

[0040] In some implementations, the control information may indicate that the target mode is the second mode. The method may also include: when the tailgate is currently in a closed state, controlling the tailgate to open based on the control information.

[0041] In this application, when the tailgate is currently closed and the target mode is the second mode, controlling the tailgate to open according to the control information can ensure the normal operation of the mode switching of the trunk lid assembly and help avoid the failure of the mode switching process due to the tailgate being closed.

[0042] In some implementations, controlling the trunk lid assembly to switch to the target mode may include: controlling the trunk lid assembly to start switching to the second mode after the tailgate is at least partially opened.

[0043] In some implementations, controlling the trunk lid assembly to switch to the target mode may include: when the tailgate opening angle is greater than or equal to a first threshold, controlling the trunk lid assembly to start switching to a second mode. Where the tailgate opening angle is the first threshold, the tailgate and the trunk lid assembly in the second mode may not be in contact.

[0044] In this application, the trunk lid assembly only begins to switch to the second mode when the tailgate opening angle is greater than or equal to a first threshold. Even if the trunk lid assembly's mode switching speed is much faster than the tailgate opening speed, the trunk lid assembly will not interfere with the tailgate during the mode switching process, ensuring the normal operation of the trunk lid assembly's mode switching.

[0045] In some implementations, the control information can also instruct the tailgate to be closed. Controlling the trunk lid assembly to switch to a target mode may include: when the current mode of the trunk lid assembly is a second mode, controlling the tailgate to close and controlling the trunk lid assembly to switch to a first mode according to the control information.

[0046] In this application, when the current mode of the trunk lid assembly is the second mode and the tailgate needs to be closed, the trunk lid assembly is switched to the first mode according to the control information, and the tailgate is closed. This helps to avoid the failure of the tailgate closing process caused by the trunk lid assembly remaining in the second mode.

[0047] In some implementations, controlling the trunk lid assembly to switch to the target mode may include: controlling the trunk lid to switch to the first mode before controlling the tailgate to close.

[0048] In this application, the tailgate is controlled to close after the trunk lid assembly is switched to the first mode. This avoids the tailgate closing failure caused by the mismatch between the tailgate closing speed and the trunk lid assembly mode switching speed, and ensures the normal operation of the tailgate closing process and the trunk lid assembly mode switching process.

[0049] In some implementations, the movement of the tailgate and the mode switching of the trunk lid assembly occur simultaneously during the second time period.

[0050] In this application, the opening / closing movement of the tailgate is synchronized with the mode switching of the trunk lid assembly during the second time period, which can shorten the user's waiting time and improve the user experience.

[0051] Thirdly, a control device is provided. This device may include modules or units for implementing the methods of the first aspect and any possible implementation thereof.

[0052] For example, the control device may include an acquisition unit and a control unit. The acquisition unit may be used to acquire control information. The control unit may be used to control the trunk lid assembly to switch to a target mode based on the control information.

[0053] For example, the control information can indicate that the target mode is the second mode, and the control unit can also be used to: control the tailgate to open when the current state of the tailgate is closed, based on the control information.

[0054] For example, control information can instruct the tailgate to be closed, and the control unit can be used to: control the tailgate to close and control the tailgate assembly to switch to the first mode when the current mode of the trunk lid assembly is the second mode, based on the control information.

[0055] Fourthly, a control device is provided. The device includes at least one processor coupled to at least one memory for storing computer programs or instructions. The at least one processor is configured to retrieve and execute the computer program or instructions from the at least one memory, causing the device to perform the methods of the second aspect and any possible implementation thereof.

[0056] Fifthly, a computer program product is provided, comprising: computer program code, which, when executed on a computer, causes the computer to perform the methods described in the second aspect and any possible implementation thereof.

[0057] In a sixth aspect, a computer-readable storage medium is provided, which stores a computer program that, when run on a computer, causes the computer to perform the methods described in the second aspect and any possible implementation thereof.

[0058] In a seventh aspect, a chip is provided, the chip including circuitry for performing the methods of the second aspect and any possible implementation thereof.

[0059] Eighthly, a vehicle is provided that may include the trunk lid assembly of the first aspect and any possible implementation thereof, or may include the means of the third or fourth aspect and any possible implementation thereof. Attached Figure Description

Detailed Implementation

[0061] As people's living standards improve, vehicles are gradually transforming from traditional means of transportation into mobile platforms adaptable to various scenarios. For example, in outdoor settings such as camping and fishing, users can use their vehicles as temporary rest areas after parking. In this case, in addition to seats, the vehicle can also utilize spaces such as the trunk to provide resting areas for users. For instance, with the tailgate open, the trunk lid / tailgate sill can form a support surface for users to sit on.

[0062] In such outdoor scenarios, sitting in the rear of the trunk is one of the most frequent user needs. Currently, vehicles often have a multi-step structure near the tailgate sill.

[0063] For example, refer to Figure 1Along the length of the vehicle, the tailgate sill, rear bumper, and other components are arranged sequentially from front to rear near the tailgate sill. The shapes of these components have stepped surfaces along the height of the vehicle, resulting in a multi-tiered, stepped structure near the tailgate sill. Here, the x-direction represents the length of the vehicle, the y-direction represents the width, and the z-direction represents the height.

[0064] When the user Figure 1 When a user sits in the position shown (i.e., the user is sitting in the rear of the trunk with their legs extending backward and hanging freely), the step difference in the multi-step structure will result in poor fit between the user's buttocks and legs and the step structure, and will cause local pressure on the user's buttocks and legs, leading to muscle soreness.

[0065] The tailgate sill may include a frame made of body sheet metal, and a sill trim panel covering the frame. For example, see... Figure 2 , Figure 1 The multi-tiered stepped structure shown can be formed by combining the exterior surfaces of multiple components such as the trunk lid 10, door sill trim, and rear bumper.

[0066] In actual implementation, even if the vehicle has a structure near the tailgate threshold that is similar to... Figure 2 There are differences; the vehicle still needs to utilize the stepped structure formed by the tailgate sill and surrounding components to achieve necessary functions (such as preventing cargo above the trunk lid 10 from shifting and ensuring a tight seal when the tailgate is closed). Figure 2 The differences between the schemes shown often lie in the number of steps and the width of the steps in the stepped structure.

[0067] exist Figure 1 In this embodiment, the vehicle employs a liftgate. The liftgate utilizes a single, rigid structure; when opened, the entire liftgate flips upwards around its top hinge, as... Figure 3 As shown in (a) of the diagram. For this type of tailgate, after the tailgate is opened, when the user... Figure 1 When seated in the trunk in the posture shown, the vehicle provides support to the user through a multi-step structure.

[0068] In some designs, to avoid the multi-tiered, stepped structure affecting the user's riding experience, the vehicle adopts a split tailgate. A split tailgate can consist of two independent structures (referred to as the upper tailgate and lower tailgate, respectively); when opening the tailgate, the upper tailgate can flip upwards around its top hinge, and the lower tailgate can flip downwards around its bottom hinge, such as... Figure 3 As shown in (b) in the diagram. For this type of tailgate, after the tailgate is opened, when the user... Figure 1 When seated in the position shown, the vehicle no longer provides support through a multi-tiered stepped structure, but rather through the lower tailgate; that is, the user can sit on the lower tailgate and extend their legs out of the trunk, allowing them to dangle freely. By rationally designing the shape of the corresponding support surfaces within the lower tailgate, the user's seating experience can be enhanced.

[0069] However, on the one hand, when using a liftgate, the vehicle needs to achieve the necessary functions (such as preventing the trunk lid from shifting) through a multi-step structure formed by the tailgate sill and its surrounding components. On the other hand, using a split tailgate would significantly increase the overall vehicle cost.

[0070] In view of this, embodiments of this application provide a trunk lid assembly and a vehicle that, while meeting the user's need to sit in the rear of the trunk, can improve the user's riding experience at a lower cost.

[0071] This trunk lid assembly can be installed in the trunk of a vehicle. The assembly includes a lid structure, a slider, and a guide rail. The guide rail is fixed along the length of the vehicle, may have a component along the vehicle's height, and its front end is lower than its rear end. The slider is mounted on the guide rail and is movable along it. The lid structure is rotatably connected to the guide rail, and the axis of rotation of the lid structure has a component along the width of the vehicle.

[0072] The following combination Figure 4 The arrangement of the guide rails and sliders is illustrated by example.

[0073] For example, Figure 4 This is a schematic diagram of a luggage cover assembly provided in an embodiment of this application.

[0074] Reference Figure 4 The trunk lid assembly 20 may include a guide rail 21, a slider 22, and a lid structure 23. The guide rail 21 may have a component in the x-axis direction and also a component in the z-axis direction. When the guide rail 21 is fixedly installed in the vehicle, it will be in a "lower front and higher rear" orientation.

[0075] The slider 22 can be set in the guide rail 21 and can move along the guide rail 21 along direction 1. Since there is an angle between direction 1 and the x-axis, and direction 1 is in a "lower in front and higher in back" posture, when the slider 22 moves from front to back along the guide rail 21, the position of the slider 22 in the z-axis direction will gradually rise.

[0076] Cover structure 23 can function as a traditional luggage cover (e.g. Figure 2 The function of the luggage lid 10 is to place items and support items placed on it.

[0077] The cover plate structure 23 can be hinged to the slider 22. For example... Figure 4 As shown, the cover plate structure 23, which is hinged to the slider 22, can rotate relative to the slider 22 about a rotation axis; the rotation axis can be the y-axis, or the rotation axis can have a component in the y-axis direction.

[0078] for Figure 4 The trunk lid assembly 20 shown has a slider 22 that is hinged to the lid structure 23. When the slider 22 moves from front to back along the guide rail 21 in direction 1, it will drive the lid structure 23 to move backward, so that the lid structure can slide backward from the trunk of the vehicle.

[0079] In the above embodiments, the extension direction of the guide rail is described by introducing the components of the guide rail in corresponding directions. It should be noted that the extension direction of the "guide rail" mentioned in this application refers to the extension direction of the "track in the guide rail for the slider to slide," and not the extension direction of the overall external shape of the guide rail. Furthermore, regarding guide rail 21, Figure 4 Only the track structure for the slider to slide in the guide rail is shown; the overall external shape of the guide rail is not fully presented. For the guide rail in the trunk lid assembly, the technical focus of this application is not on the external shape of the guide rail, and it does not limit the specific external shape of the guide rail.

[0080] In this embodiment, the guide rail 21, arranged along the length of the vehicle, forms a certain angle with the length of the vehicle in a "lower front, higher rear" manner. When the slider 22 moves from front to back in the guide rail 21, the cover plate structure 23, which is rotatably connected to the slider 22, will move backward with the slider 22, so that the cover plate structure extends backward from the trunk of the vehicle. Moreover, during the process of the cover plate structure 23 extending backward, its position in the height direction of the vehicle will gradually rise, so that the cover plate structure can be higher than the tailgate sill after extending backward, thereby overcoming the multi-step structure originally formed at the tailgate sill of the vehicle, thereby improving the user's riding experience.

[0081] Following the movement of the slider, the cover structure can be positioned at different locations along the length and height of the vehicle. This allows the trunk lid assembly to have multiple modes; in different modes, the cover structure will be in different positions.

[0082] In some implementations, the trunk lid assembly can have a first mode and a second mode. In the first mode, the entire lid structure can be positioned in front of the vehicle's tailgate sill. In the second mode, a portion of the lid structure can be positioned in front of the tailgate sill, and at least a portion of the lid structure can be positioned above and abut against the tailgate sill.

[0083] The following is Figure 4 Taking the cover plate structure shown as an example, combined with Figure 5 The first and second modes are illustrated by example. Figure 5 In the middle, the vehicle's tailgate sill and rear bumper are... Figure 2 Same; that is to say, Figure 5 This can be understood as, in Figure 2 Based on this, replace the luggage compartment lid 10 with Figure 4 The luggage compartment cover assembly shown is 20.

[0084] For example, Figure 5 This is a schematic diagram of the luggage compartment cover assembly provided in this application under different modes. (Refer to...) Figure 5 The luggage compartment cover assembly 20 can have two modes: mode 1 and mode 2.

[0085] In mode 1, slider 22 can be positioned close to the front end of guide rail 21, such as... Figure 5 As shown in (a) above. In the x-axis direction, the cover structure 23 can be positioned entirely in front of the tailgate sill. In use, the user can place objects to be stored in the trunk onto the cover structure 23, which will then support these objects. Mode 1 can correspond to the first mode.

[0086] In this mode, the trunk lid assembly 20 will be able to perform the functions of a traditional trunk lid (such as trunk lid 10) through the lid structure 23.

[0087] In mode 2, slider 22 can be positioned close to the rear end of guide rail 21, such as... Figure 5 As shown in (b) of the diagram. In the x-axis direction, one part of the cover structure 23 can be located in front of the tailgate sill; another part of the cover structure 23 can be located in the area where the tailgate sill is located, and this part is above the tailgate sill; even, yet another part of the cover structure 23 can be located behind the tailgate sill. Mode 2 can correspond to the second mode.

[0088] In this mode, when the user uses a similar Figure 1 When passengers are seated at the rear of the trunk, the vehicle will no longer carry them directly through the tailgate sill, but rather through a cover structure above the tailgate sill.

[0089] In this embodiment, in the first mode, the cover structure is positioned in front of the tailgate sill, allowing the user to place items from the trunk onto the cover structure; thus, the trunk cover assembly can perform the function of a traditional trunk cover. In the second mode, even if the tailgate sill and rear bumper still form a stepped structure, this stepped structure will be located below the cover structure. When the user needs to sit in the rear of the trunk, the vehicle will no longer directly carry the user through the stepped structure, but rather through the cover structure above the tailgate sill. Since the top of the cover structure is relatively flat, this improves the user's resting experience.

[0090] In some implementations, in the first mode, the cover structure can be lower than the tailgate sill. For example, in mode 1, the top of the cover structure 23 can be lower than the top of the tailgate sill, such as... Figure 5 As shown in (a) above. In this case, when goods placed above the cover structure by the user move backward, they will be blocked by the tailgate sill when they reach it. Conversely, in mode 1, if the top of the cover structure 23 is flush with or even higher than the tailgate sill, the goods will not be blocked by the tailgate sill when they move backward, and will directly hit the tailgate. In this embodiment of the application, in the first mode, the tailgate threshold, which is higher than the cover plate structure, can restrict the movement of goods on the cover plate structure, so as to prevent them from directly hitting the tailgate when they move backward, thereby reducing the probability of the tailgate being knocked or damaged due to the impact of goods.

[0091] The above combination Figure 5 Two models of the trunk lid assembly are illustrated below. Figure 6 The following provides an example of how to switch between these two modes.

[0092] Reference Figure 6 In mode 1, slider 22 is close to the front end of guide rail 21, and cover plate structure 23 is positioned in front of tailgate sill. In mode 1, cover plate structure 23 is in posture 1; while in mode 2, cover plate structure 23 will be in posture 4.

[0093] To change the trunk lid assembly 20 from mode 1 to mode 2, first rotate the lid structure 23 upwards around its rotation axis, causing its rear end to tilt upwards. This changes the lid structure from posture 1 to posture 2. In posture 2, the bottom of the rear end of the lid structure 23 will be higher than the tailgate sill. Then, move the slider 22 backwards. The movement of the slider 22 will move the lid structure 23, changing it from posture 2 to posture 3. When the lid structure 23 is in posture 3, the slider 22 can be close to the rear end of the guide rail 21, which corresponds to the position in mode 2. Then, rotate the lid structure 23 downwards relative to the slider 22 around its rotation axis, changing the lid structure to posture 4.

[0094] Conversely, if it is necessary to adjust the trunk lid assembly 20 from mode 2 to mode 1, the lid structure 23 can be rotated from posture 4 to posture 3 first; then, the slider 22 can be moved forward to make the lid structure 23 change to posture 2; then, the lid structure 23 can be rotated to posture 1.

[0095] In practice, users can manually operate the trunk lid assembly (e.g., manually rotate the lid structure) to switch between Mode 1 and Mode 2; alternatively, the trunk lid assembly can automatically switch modes without requiring manual rotation. For example, in cases supporting automatic mode switching, the trunk lid assembly may also include a motor or other drive mechanism, along with corresponding transmission components. Conversely, if the trunk lid assembly does not include a motor or other drive mechanism, then manual operation by the user is the only way to switch modes.

[0096] In some implementations, the trunk lid assembly may also include a support block connected to the lid structure. This support block may be located at the bottom of the lid structure and near its rear end; the main body of the support block may be made of foam material. In a second configuration, the support block may be positioned above and abut against the rear bumper.

[0097] For example, refer to Figure 7 Compared to Figure 4 The luggage compartment cover assembly 20 may also include a support block 24, the main body of which may be made of foam. The support block 24 may be disposed below the cover structure 23 by means of bonding or other methods, and the support block 24 may be arranged close to the rear end of the cover structure 23.

[0098] In Mode 2, the support block 24 can be positioned behind the tailgate sill and above the rear bumper; furthermore, in Mode 2, the support block 24 can abut against the rear bumper below it. In this case, the rear bumper can apply a certain supporting force to the support block 24 above it, and the foamed support block 24 may deform under this supporting force. Moreover, the support block 24 can apply a certain supporting force to the cover plate structure 23 above it.

[0099] for Figure 4 In the proposed solution, under mode 2, the portion of the cover structure 23 located behind the tailgate sill will form a cantilever beam with the tailgate sill, resulting in poor rigidity and load-bearing capacity of the cover structure 23 at the rear end. Furthermore, regarding... Figure 7 In mode 2, the rear bumper can support the portion of the cover structure 23 located behind the tailgate sill via the support block 24, thereby improving the stress on the cover structure.

[0100] above Figure 7 In the illustrated embodiment, the support block 24 is approximately rectangular in shape on the xz plane. In actual implementation, the support block 24 can be other shapes; for example, its bottom can have a shape that matches the top of the rear bumper to improve pressure distribution and thus avoid applying excessive pressure to the rear bumper in certain areas.

[0101] In this embodiment, the support block is located below the cover plate structure near the rear end. In the second mode, the support block is positioned above the rear bumper and can abut against it. Therefore, in the second mode, the rear bumper can support the rear end of the cover plate structure via the support block, preventing the cover plate structure from forming a long "cantilever beam" with the tailgate sill at the rear end, thus improving the load-bearing capacity of the cover plate structure in the second mode.

[0102] In some implementations, the cover plate structure may also include a first mating part. The first mating part can be used to abut against the load-bearing structure in the second mode; the load-bearing structure can be located on the vehicle body and between the guide rail and the tailgate sill.

[0103] For example, refer to Figure 8 The vehicle may include a load-bearing structure mounted on the vehicle body; in the x-axis direction, this load-bearing structure may be arranged between the slider 22 and the tailgate sill. The load-bearing structure may be installed on the vehicle body by riveting, fastener connection, or other methods. The cover plate structure 23 may include a cover plate body 231 and may also have a mating part 232 that cooperates with the load-bearing structure. In mode 2, the mating part 232 may be located above and abut against the load-bearing structure, and the load-bearing structure may support the cover plate structure 23 through the mating part 232.

[0104] Reference Figure 8 In mode 2, for the cover plate structure 23, the slider 22 can provide support near the front end, and the tailgate sill can provide support near the rear end. If no support is provided... Figure 8 The load-bearing structure shown, where the slider-cover structure-tailgate sill form a "simply supported beam," will have a large span. This results in the cover structure having poor rigidity and load-bearing capacity under the same conditions. By setting... Figure 8 The load-bearing structure shown can reduce the deformation of the cover plate structure 23 and improve its load-bearing capacity by improving the stress on the cover plate structure 23.

[0105] In addition, in Mode 1, the load-bearing structure can abut against a part other than the mating part 232 in the cover plate structure 23 to support the cover plate structure at that part; or, the load-bearing structure can not contact the cover plate structure 23 to avoid over-constraint of the cover plate structure.

[0106] In practice, this load-bearing structure can be a sheet metal part or a plastic part (such as one injection-molded from high-strength plastic). For example, the load-bearing structure can be a part that the user installs after the vehicle leaves the factory; in some implementations, to facilitate user installation of the load-bearing structure, the vehicle body can have pre-installed mounting structures (such as pre-drilled mounting holes, bolts, nuts, and other fasteners). Alternatively, the load-bearing structure can be a structure that comes with the vehicle at the factory, and this structure can be installed on the vehicle body using methods such as riveting, bonding, welding, or fastener connections.

[0107] In this embodiment, in the second mode, the first mating part can abut against the load-bearing structure disposed on the vehicle body, so that the cover plate structure can be supported by the load-bearing structure. In this way, the stress on the cover plate structure can be improved, which helps to reduce the deformation of the cover plate structure in the second mode and improves the load-bearing capacity of the trunk cover assembly.

[0108] In some implementations, the cover plate structure may also include a second mating part. This second mating part can be positioned above the tailgate sill in the second mode and abuts against the tailgate sill. In the vehicle's height direction, the second mating part is positioned higher than the first mating part. The following is combined with... Figure 9 An example is given to illustrate the relative positional relationship between the first mating part and the second mating part.

[0109] For example, Figure 9 Several structural schematic diagrams of the cover plate structure are shown.

[0110] Reference Figure 9In addition to the mating part 232, the cover plate structure 23 may also include a mating part 233; mating parts 232 and 233 may be located at different parts of the bottom of the cover plate structure 23. In mode 2, the mating part 232 may be located above the load-bearing structure and abut against the load-bearing structure; the mating part 233 may be located above the tailgate sill and abut against the tailgate sill. In mode 2, the load-bearing structure and the tailgate sill can support the cover plate structure 23 from the bottom through different parts of the bottom of the cover plate structure 23.

[0111] exist Figure 9 In this context, mating part 232 can correspond to the first mating part, and mating part 233 can correspond to the second mating part.

[0112] In one design approach, the top of the load-bearing structure can be flush with the top of the tailgate sill, such as... Figure 9 As shown in (a) of the diagram. Accordingly, in the z-axis direction, the mating part 232 can be flush with the mating part 233; the mating part 232 can be the area at the bottom of the cover body 231 for contact with the load-bearing structure; the mating part 233 can be the area at the bottom of the cover body 231 for contact with the load-bearing structure. Since the top of the load-bearing structure is flush with the top of the tailgate sill, the cover body 231 can have a uniform thickness; the cover body 231 does not need to have additional protrusions or recesses in the area corresponding to the load-bearing structure (i.e., the mating part 232), nor does it need to have additional protrusions or recesses in the area corresponding to the tailgate sill (i.e., the mating part 233), such as... Figure 9 As shown in (a) of the diagram.

[0113] In this scenario, when the trunk lid assembly is in Mode 1, if the lid structure 23 needs to be no higher than the tailgate sill, a corresponding clearance structure needs to be provided on the lid body 231 to prevent the lid structure 23 from interfering with the load-bearing structure in Mode 1. The presence of this clearance structure may expose the load-bearing structure to the user's view, thereby affecting the shape and aesthetics of the trunk.

[0114] In another design approach, the top of the load-bearing structure can be lower than the top of the tailgate sill, such as... Figure 9 As shown in (b) and (c) above. In the z-axis direction, the position of mating part 233 can be higher than the position of mating part 232. Figure 9 Compared to (a) in the previous example, by reasonably setting the structure of the mating part 232, it is possible to avoid interference between the cover plate structure and the load-bearing structure in mode 1, without having to set a specific avoidance structure on the cover plate body 231 to avoid interference with the load-bearing structure.

[0115] In this design, since the mating parts 232 and 233 are at different heights, the bottom of the cover plate structure 23 can have a stepped structure. When the top of the cover plate structure 23 is planar or nearly planar, the cover plate structure can have different thicknesses in different locations.

[0116] In one example, refer to Figure 9 In (b), the thickness of the cover body 231 is 1. The cover body 231 does not have a protruding or recessed structure at the mating portion 232, so that the mating portion 232 and its surrounding area have the same thickness (i.e., thickness 1). The cover body 231 can be recessed upwards at the mating portion 233. Correspondingly, while this recessed structure forms the mating portion 233 that mates with the tailgate sill, the cover structure 23 will have a thinner thickness (i.e., thickness 2) at this recess. In this design, at the bottom of the cover structure 23, there will be a stepped structure between the mating portions 232 and 233. The above... Figures 4 to 8 The luggage compartment lid assembly shown uses... Figure 9 The cover plate structure shown in (b) is shown in the figure.

[0117] In another example, refer to Figure 9 In (c), the thickness of the cover body 231 is 3. The cover body 231 can protrude downward at the mating part 232 to form a mating part 232 that mates with the load-bearing structure; the cover body 231 can also be recessed upward at the mating part 233 to form a mating part 233 that mates with the tailgate sill. Figure 9 As shown in (c), the thickness of the cover plate structure 23 at the mating part 232 is still thickness 1, and the thickness at the mating part 233 is still thickness 2. Thickness 3 is less than thickness 1 and greater than thickness 2.

[0118] In this design, at the bottom of the cover plate structural member 23, there can be a multi-level stepped structure between the mating parts 232 and 26. Compared to Figure 9 In (b), this scheme allows the cover body to have a thinner thickness, which is beneficial for the lightweighting of the cover structure.

[0119] above Figure 8 and Figure 9 In one embodiment, the mating parts 232 and 233 can be formed by protrusions or recesses at corresponding locations on the cover plate body 231. In other embodiments, the mating parts 232 and 233 can have more complex structures. For example, the mating part 232 can have a locking structure. In addition to supporting the cover plate structure 23 through the mating part 232, the supporting structure can also restrict the movement of the cover plate structure through the locking structure on the mating part 232 to ensure the stability of the cover plate structure 23 in mode 2.

[0120] In some implementations, the load-bearing structure may have a locking hole, and the first mating part may have a locking pin that mates with the locking hole. When the locking pin is in the locking hole, it can be used to: restrict the movement of the cover plate structure in at least one of the length and height directions of the vehicle. The following is combined with... Figures 10 to 12 This will be illustrated by example.

[0121] For example, Figure 10 This is a schematic diagram of a mating part 232 provided in an embodiment of this application.

[0122] Reference Figure 10 The mating part 232 may be provided with a locking pin along the z-direction, and the top of the supporting structure may be provided with a locking hole along the z-direction. During the switching of the luggage compartment cover assembly 20 to mode 2, as the cover structure 23 rotates downwards along the rotation axis, the locking pin in the mating part 232 gradually approaches the locking hole in the supporting structure, ultimately locking within the locking hole. In mode 2, the locking pin in the mating part 232 will be positioned within the locking hole of the supporting structure; since the locking pin and locking hole are arranged along the z-direction, the locking hole can restrict the movement of the locking pin along the x-direction, thereby restricting the movement of the cover structure 23 in the x-direction.

[0123] In some embodiments, the mating part 232 and the cover plate body 231 can be the same part. For example, the cover plate body 231 can be made by injection molding. The locking pin in the mating part 232 can be formed directly by mold during the injection molding of the cover plate body 231; or, it can be formed by drilling or other processes at the bottom of the cover plate body 231 after the cover plate body 231 has been injection molded.

[0124] In some embodiments, the mating part 232 and the cover body 231 can be different parts. For example, the mating part 232 can be installed on the bottom of the cover body 231 by fasteners as a separate part.

[0125] exist Figure 10 In the design, the locking pin in the mating part 232 is a regular column shape. In actual implementation, the locking pin can have other regular or irregular shapes. For example, refer to... Figure 11 In (a), the locking pin can be wedge-shaped.

[0126] Additionally, in some embodiments, with Figure 10 Conversely, a locking post can be installed at the top of the load-bearing structure, and a corresponding locking hole can be provided in the mating part 232, such as... Figure 11 As shown in (b) of the diagram. (and) Figure 10 Compared to the previous solution, if the cover plate structure 23 has a locking hole in the mating part 232, the cover plate structure 23 will have a thinner thickness at the locking hole, which may result in poorer rigidity of the cover plate structure 23 at the locking hole.

[0127] For example, Figure 12 This is another structural schematic diagram of the mating part 232 provided in the embodiments of this application.

[0128] Reference Figure 12 The mating part 232 may include a locking pin arranged along the y-direction, and the supporting structure may include a lock hole arranged along the y-direction. The mating part 232 may also include a locking rod 25 for mounting the locking pin. The top end of the locking rod 25 may form a rotating pair with the cover plate body 231, and the rotation axis of the locking rod 25 may be along the x-axis; the locking pin may be located at the bottom end of the locking rod 25. This arrangement allows the locking rod 25 to rotate about its top end along an axis arranged along the x-axis, and the rotation of the locking rod 25 will cause the locking pin to extend and retract in the lock hole along the y-direction.

[0129] During the transition from mode 2 to mode 2, the cover assembly 20 rotates downwards along the rotation axis, causing the locking rod 25 to rotate downwards, bringing the locking pin close to the height of the lock hole in the supporting structure. After the locking pin aligns with the lock hole, rotating the locking rod 25 allows the locking pin to extend and retract within the lock hole, thereby achieving locking and unlocking.

[0130] Compared to Figure 10 , Figure 12 In the proposed solution, the keyhole can restrict the movement of the locking pin in the x and z directions, thereby restricting the movement of the cover plate structure 23 in the x and z directions.

[0131] Furthermore, the locking and unlocking methods differ between the two schemes. Specifically, taking locking as an example, in... Figure 10 In this scheme, when switching to mode 2, the lock pin moves in a z-axis direction when the cover plate structure 23 rotates downward. Since the lock pin and the lock hole are set along the z-axis, as the cover plate structure 23 rotates, the lock pin will first approach the lock hole and then extend into the lock hole.

[0132] exist Figure 12 In this scheme, during the switch to mode 2, when the cover plate structure 23 rotates downwards, the movement direction of the locking pin and locking rod has a component in the z-axis direction, but no component in the y-axis direction. Since the locking pin and the lock hole are set along the y-axis, for the locking pin, the rotation of the cover plate structure 23 can only align the locking pin with the lock hole, but cannot drive the locking pin to extend or retract within the lock hole. After the locking pin is aligned with the lock hole, the user needs to manually rotate the locking rod 25, or drive the locking rod 25 to rotate through a motor or other device, so that the locking pin extends into the lock hole.

[0133] In users with similar Figure 1When sitting on the rear of the trunk lid assembly, if the lid structure moves due to insecure fixing, the user may fall off the trunk lid assembly. In this embodiment, by providing a lock hole on the load-bearing structure and a lock pin that engages with the lock hole in the first mating part, the movement of the lid structure can be restricted by the engagement of the lock pin and the lock hole, thereby improving the stability of the lid structure in the second mode and preventing the user from falling off the lid structure due to instability.

[0134] In some implementations, the trunk lid assembly may also include an operating handle disposed on the lid structure. This operating handle is drively connected to the lock cylinder via a first transmission assembly. The operating handle can be used to drive the lock cylinder to extend or retract within the keyhole to achieve locking and unlocking.

[0135] For example, cover plate structural member 23 can be adopted Figure 12 The illustrated solution enables locking and unlocking. Accordingly, to facilitate the extension and retraction of the locking pin within the keyhole, the trunk lid assembly may also include an operating handle that is driveably connected to the locking rod 25. In use, the user can rotate the operating handle to rotate the locking rod 25 around its top, thereby causing the locking pin to extend and retract within the keyhole, achieving locking / unlocking.

[0136] In some implementations, the first transmission assembly may include a first locking rod connected to the operating handle and a second locking rod connected to the locking pin. The operating handle can drive the first locking rod to rotate, thereby causing the second locking rod and the locking pin to rotate around the axis of the second locking rod, thus enabling the locking pin to extend and retract within the keyhole.

[0137] by Figure 4 Taking the illustrated trunk lid assembly as an example, in Mode 2, the lid structure 23 is positioned above and abuts against the tailgate sill. If the operating handle is located at the rear end of the lid structure 23, the transmission assembly between the operating handle and the locking pin would need to extend from the front of the tailgate sill to the rear, significantly increasing the difficulty of arranging this assembly. Therefore, the operating handle can be positioned on the left or right side of the lid structure. The following... Figure 13 Taking the example of the operating handle being located on the left side of the cover plate structure, the first transmission assembly is described exemplarily.

[0138] For example, Figure 13 This is a schematic diagram of the transmission method between the operating handle and the locking pin provided in an embodiment of this application.

[0139] and Figure 12 Similarly, the keyhole and lock pin can be positioned along the y-axis. For example... Figure 13As shown, the operating handle can be connected to the locking pin via a transmission assembly consisting of locking rods 25 and 26. The operating handle can be located on the left side of the cover plate structure; locking rods 25 and 26 can be located at the bottom of the cover plate structure.

[0140] Reference Figure 13 The locking rod 25 may include a rotating shaft 251 and a connecting rod 252; the rotating shaft 251 may be arranged along the x-direction, the top end of the connecting rod 252 may be connected to the rotating shaft 251, and the locking pin arranged along the y-direction may be arranged at the bottom end of the connecting rod 252; the rotating shaft 251 may form a rotating pair with the cover plate body 231. Figure 13 (Not shown), the axis of rotation can be the axis of the rotating shaft 251 itself. This structure allows the locking bar 25 to rotate about its top end and along the x-axis (i.e., the axis of the rotating shaft 252 itself), and the rotation of the locking bar 25 will cause the locking pin to extend and retract in the lock hole along the y-direction.

[0141] One end of the locking rod 26 may be equipped with an operating handle, and the other end may be connected to the rotating shaft 251 via a transmission connection (e.g., through gears, universal joints, etc.). The locking rod 26 may form a rotating pair with the cover plate body 231, allowing the locking rod 26 to rotate along its own axis.

[0142] The locking lever 26 can be positioned in different directions from the rotating shaft 251. For example, the rotating shaft 251 can be positioned along the x-axis, and the locking lever 26 can be positioned along the y-axis, as shown below. Figure 13 As shown. In this configuration, when the user rotates the operating handle, the operating handle will cause the locking rod 26 to rotate around the y-axis, which in turn causes the locking rod 25 to rotate around the x-axis; when the locking rod 25 causes the locking pin to rotate around the x-axis, the locking pin will have a component of movement along the y-axis, allowing the locking pin to extend and retract within the keyhole, thereby achieving locking and unlocking.

[0143] In practical implementation, the locking rod 25 can be provided with one or more locking pins. Correspondingly, the locking rod 25 can include one or more connecting rods 252, and the supporting structure can be provided with one or more corresponding lock holes; the locking pins, connecting rods 252, and lock holes can correspond one-to-one. For example, refer to... Figure 13 The load-bearing structure can be provided with three lock holes, which can be spaced apart along the x-direction; correspondingly, the locking rod 25 can include three connecting rods 252 spaced apart along the x-direction, and the bottom of each connecting rod 252 can be provided with a locking pin arranged along the y-direction.

[0144] In addition, to improve the strength of the cover plate structural component 23, reinforcing bars can be provided on the cover plate body 231. For example, if the cover plate body 231 is an injection molded part, reinforcing bars can be installed at the bottom of the cover plate body 231, such as... Figure 13 As shown. In one design, the reinforcing rod is a metal rod.

[0145] As mentioned earlier, in one design approach, the trunk lid assembly may not have a motor or other driving components, and only supports manual mode switching by the user. In another design approach, the trunk lid assembly may be equipped with a motor and corresponding transmission components, which can support automatic mode switching according to user needs. For example, the motor can drive the slider 22 to move along the guide rail 21. As another example, the motor can drive the lid structure 23 to rotate around the slider.

[0146] For luggage compartment cover assemblies that only support manual mode switching by the user, the following can be adopted: Figures 10 to 13 The solution restricts the movement of the cover structure components. However, for luggage compartment cover assemblies that support automatic mode switching, even without using... Figures 10 to 13 The solution shown can also limit the movement of the cover plate structure to a certain extent through the self-locking of the motor.

[0147] In some implementations, the trunk lid assembly may further include a first motor, a second motor, and a second transmission assembly. The first motor may be fixedly mounted on the vehicle and connected to the slider via the second transmission assembly; the first motor may be used to drive the slider to move along the guide rail. The second motor may be used to drive the lid structure to rotate relative to the slider.

[0148] The following combination Figure 14 The transmission method between the first motor and the slider is illustrated by an example.

[0149] For example, Figure 14 This is a schematic diagram of the transmission method between the first motor and the slider provided in the embodiments of this application.

[0150] For example, such as Figure 14 As shown in (a), the output end of the motor 31 can be connected to the gear 32, the gear 32 can mesh with the rack 33, and the rack 33 can be fixedly mounted on the slider 22. When the motor 31 rotates, it can drive the gear 32 to rotate, thereby driving the rack 33 and the slider 22 to move along the guide rail 21. In this example, the second transmission component may include the gear 32 and the rack 33.

[0151] For example, such as Figure 14 As shown in (b), a pulley can be provided at each of the upper and lower ends of the guide rail 21; where pulley 34 is the driving pulley and pulley 35 is the driven pulley. The output end of the motor 31 can be connected to pulley 34; the slider 22 can be fixedly connected to the belt 36 (e.g., glued to the belt, or mounted on the belt with bolts or other fasteners). When the motor 31 rotates, it can drive the belt 36 to move through pulley 34, thereby driving the slider 22 to move along the guide rail 21. In this example, the second transmission component may include pulley 34, pulley 35, and belt 36.

[0152] For example, compared to Figure 14 In (b), the belt drive can be replaced with a chain drive.

[0153] In the case of a gear-rack drive, the rack moves along the guide rail together with the slider. When the slider's stroke is large, the rack needs to be longer, resulting in a larger installation space. In the case of a belt drive, a lighter cover plate structure is required to prevent the belt from deforming due to excessive load and to prevent slippage between the belt and the pulley due to excessive load.

[0154] In some implementations, to save space in the second transmission assembly and to improve the control precision of the slider's movement, the trunk lid assembly can use a lead screw to convert the motor's rotation into the linear motion of the slider along the guide rail. In other words, the second transmission assembly can include a lead screw that is driven and connected to the first motor, and the slider can be driven and connected to the lead screw.

[0155] For example, refer to Figure 14 In (c), the motor 31 can be fixedly mounted on the vehicle, and the output end of the motor 31 can be connected to the lead screw 37 to drive the lead screw 37 to rotate. The lead screw 37 can pass through the slider 22 and be connected to the slider 22. Since the slider 22 is connected to the lead screw 37 and the guide rail 21 restricts the rotation of the slider 22 around the lead screw 37, the slider 22 will slide along the guide rail 21 when the motor 31 drives the lead screw 37 to rotate.

[0156] Compared to gear-rack transmission, screw transmission reduces the space required for the second transmission component; compared to belt transmission, screw transmission enables more precise control of the slider's movement and is applicable to a wider range of scenarios (such as scenarios where the cover plate structure is heavy).

[0157] The above combination Figure 14 The operation of the first motor is illustrated by example. The following, in conjunction with... Figure 15 The working method of the motor used to drive the rotation of the cover plate structure is illustrated by way of example.

[0158] For example, Figure 15 This is a schematic diagram of one working mode of the second motor provided in the embodiments of this application.

[0159] Reference Figure 15The trunk lid assembly 20 may also include a motor 41, which can be fixed to the vehicle body. The output end of the motor 41 can be connected to a gear 42, which can mesh with a rack 43. A support block 44 can be provided at the top of the rack 43. The support block 44 can be located below the cover structure 23 and can abut against the cover structure 23 to support it. When the motor 41 rotates, it can drive the gear 42 to rotate, which in turn drives the rack 43 and the support block 44 to move in the z-direction. As the support block 44 rises continuously under the action of the motor 41, it can lift the cover structure 23 from below. Since the cover structure 23 is hinged to the slider 22 and the guide rail 21 can restrict the rotation of the slider 22 in the y-direction, the cover structure 23 will rotate upward around the slider 22 when it is lifted by the support block 44.

[0160] exist Figure 15 In this scheme, after the support block 44 lifts the cover plate structure 23 upwards, the cover plate structure 23 will slide on the support block 44 during the movement of the slider 22 along the guide rail; and noise may be generated due to friction between the cover plate structure 23 and the support block 44 during the sliding process.

[0161] In some implementations, to reduce noise, the second motor can be mounted on the cover plate structure, and a gear set can be used to connect the second motor and the slider. For example, the second motor can be fixedly mounted on the cover plate structure and connected to the slider via a third transmission assembly. The third transmission assembly may include a first gear connected to the second motor and a second gear connected to the slider. The first gear and the second gear can be driven together.

[0162] For example, Figure 16 This is a schematic diagram illustrating another operating mode of the second motor provided in an embodiment of this application. Wherein, Figure 16 (a) in the image uses a side view perspective. Figure 16 (b) in the image uses a top-down view perspective.

[0163] like Figure 16 As shown, the motor 41 can be fixedly mounted on the cover plate structure 23, and its output end can be connected to the gear 45; the slider 22 can be connected to the gear 46 via the rotating shaft 47; the gear 45 can mesh with the gear 46. The cover plate structure 23 can be provided with a through hole along the y-direction; the rotating shaft 47 can pass through this through hole and form a rotating pair with the cover plate structure 23. Thus, the cover plate structure 23 will be able to rotate relative to the slider 22 about the rotating shaft 47.

[0164] Since the rotation of slider 22 in the y-direction is restricted by guide rail 21, gear 46, which is connected to slider 22 via shaft 47, will be unable to rotate along the y-axis. In this case, gear 45 will rotate around the axis of gear 46 (i.e., the axis of shaft 47) while rotating on its own axis. Since motor 41 is fixedly mounted on cover plate structure 23, when motor 41 drives gear 45 to rotate, motor 41, gear 45, and cover plate structure 23 will rotate together around shaft 47, thereby realizing the automatic rotation of cover plate structure 23 around slider 22.

[0165] exist Figure 16 In this design, motor 41 is connected to the slider via a gear set consisting of gears 45 and 46; gear 45 can correspond to the first gear, and gear 46 can correspond to the second gear. In other implementations, this gear set may include more gears. For example, with... Figure 16 In the different configuration, gear 45 no longer meshes with gear 46, and the two gears can be connected by one or more other gear drives.

[0166] Compared to Figure 15 The plan, Figure 16 In the proposed solution, the motor drives the cover plate structure to rotate through a gear set, which has significant advantages in terms of noise and layout space.

[0167] In the above Figures 4 to 16 In the illustrated scheme, guide rail 21 is straight. In other implementations, guide rail 21 can have more complex shapes. For example, in... Figure 4 Based on the scheme, in addition to a section of track set along direction 1, guide rail 21 may also include another section of track set along the x-axis; these two sections of track can be connected, so that the overall track in guide rail 21 presents a broken line shape. Regardless of the overall shape of the track in the guide rail for the slider to slide, the entire track needs to include at least one section of track arranged along the length of the vehicle and set in a "lower front, higher back" manner.

[0168] The above combination Figures 4 to 16 The luggage compartment cover assembly provided in the embodiments of this application has been described by way of example. The following description, in conjunction with... Figure 17 The control method provided in the embodiments of this application is illustrated by way of example.

[0169] For example, Figure 17 This is a schematic flowchart of the control method provided in an embodiment of this application. The method can be executed by the trunk lid assembly, or by a control device or its components (such as a processor, processing circuit, or chip) of the trunk lid assembly, or by a vehicle equipped with the trunk lid assembly or the aforementioned control device. The method may include: S310, acquire control information.

[0170] The control information can indicate the target mode of the trunk lid assembly, which may include a first mode or a second mode.

[0171] For a description of the trunk lid assembly, the first mode, and the second mode, please refer to the above. Figures 4 to 16 The relevant embodiments are described in detail here.

[0172] In one example, the control information can be obtained based on the detected voice command. For instance, when a user's voice command "Extend the trunk lid" is detected, the target mode can be determined to be the second mode. As another example, when the trunk lid assembly is in the first mode, and a user's voice command "Close the tailgate" is detected, the target mode can be determined to be the second mode.

[0173] In another example, the control information can be obtained based on the user's manipulation of physical or virtual buttons. For instance, a vehicle may have a physical or virtual button for switching the mode of the trunk lid assembly, and the user's desired mode can be determined based on the user's manipulation of the button.

[0174] In another example, the mode of the trunk lid assembly can be associated with the vehicle's state. For instance, the vehicle can be configured with a camping mode, in which the tailgate can be preset to the open state, and the trunk lid assembly can be preset to a second mode; when a user's need to switch the vehicle to camping mode is detected, the target mode of the trunk lid assembly can be determined to be the second mode.

[0175] S320, based on the control information, controls the trunk lid assembly to switch to the target mode.

[0176] For example, the mode switching of the trunk lid assembly can be achieved by controlling the relevant drive device. For instance, during the mode switching process of the trunk lid assembly 20, the rotation process of the lid structure 23 around the rotation axis can be controlled by controlling the motor 41; the movement process of the slider 22 along the guide rail 21 can be controlled by controlling the motor 31.

[0177] In one implementation, the trunk lid assembly can be in a first mode before mode switching, and control information can indicate that the target mode is a second mode. Controlling the trunk lid assembly to switch to the target mode according to the control information can include: controlling the lid structure to rotate around a rotation axis in a first direction to a first posture; controlling a slider to move the lid structure backward along a guide rail while the lid structure is in the first posture; and controlling the lid structure to rotate around a first preset position in the opposite direction of the first rotation axis when the slider reaches a first preset position. In the first posture, the entire lid structure can be positioned in front of the tailgate sill, and the bottom of the rear end of the lid structure can be higher than the tailgate sill; when the slider reaches the first preset position, a portion of the lid structure is above the tailgate sill.

[0178] For example, refer to Figure 6 When switching from Mode 1 to Mode 2, the cover plate structure 23 can be controlled to rotate counterclockwise so that its rear bottom is higher than the tailgate sill. At this time, since the slider has not started to move backward, the cover plate structure 23 is still in front of the tailgate sill. When the rotation of the cover plate structure 23 stops, the slider 22 can be controlled to move backward along the guide rail 21 so that the cover plate structure 23 is above the tailgate sill. When the slider 22 moves backward to the position corresponding to Mode 2, the cover plate structure 23 can be controlled to rotate clockwise until the bottom of the cover plate structure 23 abuts against the tailgate sill.

[0179] In this example, the posture of the cover plate structure 23 when it stops rotating counterclockwise can correspond to the first posture; the position of the slider in mode 2 can correspond to the first preset position; the counterclockwise direction can correspond to the first direction, and the clockwise direction can correspond to the opposite direction of the first direction. Moreover, in this example, the rotation of the cover plate structure 23 and the movement of the slider 22 do not occur simultaneously.

[0180] For example, refer to Figure 18 When switching from Mode 1 to Mode 2, the cover structure 23 can be controlled to rotate counterclockwise so that its rear bottom is higher than the tailgate sill. With the rear of the cover structure 23 higher than the tailgate sill, the slider 22 can be controlled to move backward along the guide rail 21, and the cover structure 23 can continue to rotate counterclockwise. When the rotation angle of the cover structure 23 reaches a preset angle threshold, the rotation of the cover structure 23 can be stopped, and the slider 22 can continue to move backward along the guide rail 21. When the slider 22 moves backward to a preset position (which can correspond to the first preset position), the cover structure 23 can be controlled to rotate clockwise, and the slider 22 can continue to move backward. When the slider 22 moves backward to the position corresponding to Mode 2, the slider 22 can be controlled to stop moving, and the cover structure 23 can continue to rotate clockwise until the bottom of the cover structure 23 abuts against the tailgate sill.

[0181] In this example, the posture of the cover plate structure 23 when the slider 22 begins to move backward can correspond to the first posture; the position of the slider when the cover plate structure 23 begins to rotate clockwise can correspond to the first preset position. Moreover, in this example, the rotation of the cover plate structure 23 can be performed simultaneously with the movement of the slider 22.

[0182] In this embodiment, before the slider moves backward, the cover plate structure is rotated so that the bottom of its rear end is higher than the tailgate sill, thus preventing interference between the cover plate structure and the tailgate sill during the slider's backward movement. After part of the cover plate structure is above the tailgate sill, the cover plate structure is then rotated in the opposite direction, preventing the cover plate structure from failing to be above the tailgate sill after rotating in the opposite direction of the first direction.

[0183] In some implementations, the first preset position may include the position of the slider in the second mode.

[0184] For example, such as Figure 6 As shown, after the slider moves backward to the position corresponding to mode 2, the rear part of the cover structure 23 will be above the tailgate sill. At this time, the slider can be stopped and the cover structure 23 can be rotated clockwise until the bottom of the cover structure abuts against the tailgate sill.

[0185] Because the bottom of the cover plate structure may have a stepped structure, if the control precision is poor when the slider moves and the cover plate structure rotates simultaneously, unintended interference may occur as the cover plate structure rotates around the rotation axis toward the tailgate threshold. In this embodiment, after the slider moves backward to the position corresponding to the second mode, the cover plate structure is then controlled to rotate in the opposite direction of the first direction. This helps to reduce the requirement for control precision and also helps to avoid unintended interference under lower control precision.

[0186] In some implementations, the trunk lid assembly can be in a second mode before mode switching, and the control information can indicate that the target mode is the first mode. Controlling the trunk lid assembly to switch to the target mode according to the control information can include: controlling the lid structure to rotate around its rotation axis in a first direction to a second posture; controlling a slider to move the lid structure forward along a guide rail while the lid structure is in the second posture; and controlling the lid structure to rotate around its rotation axis in the opposite direction of the first direction when the slider reaches a second preset position. In the second posture, the lid structure is above the tailgate sill but not in contact with it.

[0187] For example, with Figure 6Conversely, when switching from Mode 2 to Mode 1, the cover structure 23 can be controlled to rotate counterclockwise so that it no longer contacts the tailgate sill. When the rotation of the cover structure 23 stops, the slider 22 can be controlled to move forward along the guide rail 21 until the entire cover structure 23 is in front of the tailgate sill. When the slider 22 moves forward to the position corresponding to Mode 1, the cover structure 23 can be controlled to rotate clockwise until the cover structure 23 is in the posture corresponding to Mode 1.

[0188] In this example, the posture of the cover plate structure 23 when it stops rotating counterclockwise can correspond to the second posture; the position of the slider 22 in mode 1 can correspond to the second preset position.

[0189] For example, with Figure 18 Conversely, when switching from Mode 2 to Mode 1, the cover structure 23 can be controlled to rotate counterclockwise so that it no longer contacts the tailgate sill. If the z-axis distance between the cover structure 23 and the tailgate sill is greater than a certain threshold (e.g., 20 mm), the slider 22 can be controlled to move forward along the guide rail 21, and the cover structure 23 can continue to rotate counterclockwise. When the rotation angle of the cover structure 23 reaches a preset angle threshold, the rotation of the cover structure 23 can be stopped, and the slider 22 can continue to move forward along the guide rail 21. When the slider 22 moves forward to a preset position (which can correspond to a second preset position), the cover structure 23 can be controlled to rotate clockwise, and the slider 22 can continue to move forward along the guide rail 21. When the slider 22 moves forward to the position corresponding to Mode 1, the slider 22 can be stopped, and the cover structure 23 can continue to rotate clockwise until the cover structure 23 is in the posture corresponding to Mode 1.

[0190] In this example, the second preset position can be between the position of the slider in mode 1 and its position in mode 2.

[0191] In this embodiment, before the slider moves forward, controlling the rotation of the cover plate structure to prevent it from contacting the tailgate sill can avoid frictional noise caused by the cover plate structure contacting the tailgate sill when the slider moves forward. Furthermore, after the cover plate structure is positioned in front of the tailgate sill, controlling its rotation can prevent the cover plate structure from failing to return to the posture corresponding to the first mode after moving in the opposite direction of the first direction.

[0192] In some implementations, the second preset position may include the position of the slider in the first mode.

[0193] For example, after the slider moves forward to the position corresponding to Mode 1, the cover structure 23 will be positioned in front of the tailgate sill. At this point, the slider can be stopped, and the cover structure 23 can be rotated clockwise until it reaches the posture corresponding to Mode 1.

[0194] Since the bottom of the cover plate structure may have a stepped structure, if the control precision is poor when the slider moves and the cover plate structure rotates simultaneously, the cover plate structure may unexpectedly interfere with the tailgate sill during its rotation around the rotation axis. In this embodiment, controlling the cover plate structure to rotate in the opposite direction of the first direction after the slider movement stops helps reduce the requirement for control precision and also helps avoid unexpected interference under lower control precision.

[0195] In some implementations, the movement of the slider along the guide rail and the rotation of the cover plate structure around the rotation axis can occur simultaneously during the first time period.

[0196] The first time period can be any duration; within this time period, the movement of the slider and the rotation of the cover plate structure occur simultaneously. For example, refer to... Figure 18 During the transition from mode 1 to mode 2, when the cover plate structure 23 rotates counterclockwise until its rear end is higher than the tailgate threshold, the slider 22 can be controlled to move backward along the guide rail 21, and the cover plate structure 23 can be controlled to continue rotating counterclockwise.

[0197] In this embodiment, during the first time period of the mode switching process, the movement of the slider is synchronized with the rotation of the cover plate structure, which can shorten the overall switching time.

[0198] In some implementations, the control information may indicate that the target mode is the second mode. The method may also include: when the tailgate is currently in a closed state, controlling the tailgate to open based on the control information.

[0199] For example, Figure 19 This is a schematic diagram showing the relative positional relationship between the trunk lid assembly and the tailgate in different states provided in the embodiments of this application.

[0200] In Mode 1, the cover structure 23 of the trunk lid assembly 20 will be positioned in front of the tailgate sill, and there will be no interference between the two even if the tailgate is closed.

[0201] like Figure 19As shown, the tailgate has different gaps with the trunk lid assembly 20 when it is in different states. When the trunk lid assembly 20 is in mode 2, if the tailgate is closed, the tailgate and the cover structure 23 will interfere; that is, the vehicle cannot simultaneously have a closed tailgate and a trunk lid assembly in mode 2. The tailgate opening angle must be at least equal to angle 1 to ensure that the tailgate does not interfere with the cover structure 23 in mode 2.

[0202] During the transition from Mode 1 to Mode 2 of the trunk lid assembly 20, the slider 22 will cause the lid structure 23 to move backward. If the tailgate remains closed, the closed tailgate will interfere with the movement of the lid structure 23 during the transition, preventing the trunk lid assembly from switching to Mode 2. To ensure proper mode switching, if the control information indicates that Mode 2 is the target mode, the tailgate can be opened according to this control information.

[0203] above Figure 19 Taking the top-hinged tailgate as an example, the relative positional relationship between the trunk lid assembly and the tailgate in different states is illustrated. Similar to the top-hinged tailgate, other types of tailgates (such as side-opening tailgates) will also interfere with the movement of the cover structure 23 when they are closed or at a small opening angle, causing the trunk lid assembly to be unable to switch to mode 2.

[0204] In this embodiment, when the tailgate is currently closed and the target mode is the second mode, controlling the tailgate to open according to the control information can ensure the normal switching of the trunk lid assembly mode and help avoid the mode switching process being blocked because the tailgate is closed.

[0205] In some implementations, controlling the trunk lid assembly to switch to the target mode may include: controlling the trunk lid assembly to start switching to the second mode after the tailgate is at least partially opened.

[0206] For example, Figure 20 This is a schematic diagram of the mode switching control method for the luggage compartment cover assembly provided in the embodiments of this application.

[0207] Reference Figure 20 Before mode switching, the tailgate can be in the closed state, and the trunk lid assembly 20 is in mode 1; the target mode of the trunk lid assembly is mode 2. In order to cooperate with the mode switching of the trunk lid assembly 20, the tailgate needs to be switched from the closed state to the open state.

[0208] For the tailgate, the moment it begins to open is denoted as time A, the moment it reaches an opening angle of 1 is denoted as time B, and the moment it reaches a fully open state is denoted as time C; time A is earlier than time B, and time B is earlier than time C. For the trunk lid assembly 20, the moment it begins to switch from mode 1 is denoted as time 1, the moment the slider begins to move backward during the mode switching process is denoted as time 2, and the moment the mode switching ends is denoted as time 3; time 2 is later than time 1 and earlier than time 3. A fully open tailgate can indicate that the current opening angle of the tailgate has reached the maximum opening angle or a preset opening angle; this preset opening angle can be set by the user or preset by the vehicle manufacturer.

[0209] In some embodiments, the trunk lid assembly can begin mode switching when the tailgate is fully open. For example, time 1 may not be earlier than time C; that is, time 1 may be the same as time C, such as... Figure 20 As shown in (a), time 1 can also be later than time C. In this mode, when the cover structure of the trunk lid assembly slides out of the trunk, the tailgate is already fully open, and there is no interference between the two.

[0210] In other embodiments, the trunk lid assembly can begin mode switching when the tailgate opening angle reaches at least angle 1. For example, time 1 may not be earlier than time B, such as... Figure 20 As shown in (b) of the diagram.

[0211] Since the tailgate opening angle reaches angle 1 at time B, the tailgate opening angle will be greater than angle 1 thereafter. Furthermore, when the tailgate opening angle reaches angle 1, even if the trunk lid assembly is in mode 2, it will not interfere with the tailgate. Additionally, sometime between time B and time C, the tailgate opening and the trunk lid assembly mode switching will occur simultaneously. Figure 20 Compared to (a) in the previous method, this method can shorten the time from time A to the end of the trunk lid assembly mode switching.

[0212] In other embodiments, the trunk lid assembly can be controlled to switch modes before the tailgate opening angle reaches angle 1; the slider can be controlled to start moving backward along the guide rail when the tailgate opening angle has at least reached angle 1. For example, as Figure 20As shown in (c), time 1 can be later than time A and earlier than time B, and time 2 can be no earlier than time B. That is, the trunk lid assembly can begin mode switching some time after the tailgate has started opening; when the tailgate opening angle reaches at least angle 1, the slider 22 begins to move backward along the guide rail 21. In this case, even if the lid structure 23 has already rotated to the corresponding posture before time B, the lid structure 23 needs to maintain this posture until time B before the slider 22 begins to move backward.

[0213] In some other embodiments, since the trunk lid assembly 20 needs to rotate the lid structure 23 and then slide the slider 22 backward during the process of switching from mode 1 to mode 2, the trunk lid assembly 20 can be controlled to switch from mode 1 to mode 2 at the same time as the tailgate begins to open. Figure 20 As shown in (d), time 1 and time A can be the same time.

[0214] and Figure 20 Compared to (a) to (c), Figure 20 The solution shown in (d) requires high precision control over the trunk lid assembly and tailgate. For example, as... Figure 20 As shown in (d), if the control precision is poor, the time required for the trunk lid assembly to switch from mode 1 to mode 2 (i.e., the time between time 1 and time 3) is less than the time required for the tailgate to open from the closed state to angle 1 (i.e., the time between time A and time B), then when the trunk lid assembly switches to mode 2, the opening angle of the tailgate will be less than angle 1, that is, there will be interference between the two.

[0215] In addition, users often place items in the trunk. Figure 20 In the scheme shown in (d), the tailgate is not opened when the trunk lid assembly begins to switch modes, making it difficult for users to remove items placed on the trunk lid assembly in a timely manner. During the trunk lid assembly mode switching process, the lid structure will rotate around the rotation axis, which may cause the items placed on it to shift, thus requiring users to rearrange the items on it, affecting the user experience.

[0216] In some implementations, controlling the trunk lid assembly to switch to the target mode may include: when the tailgate opening angle is greater than or equal to a first threshold, controlling the trunk lid assembly to start switching to a second mode. Where the tailgate opening angle is the first threshold, the tailgate and the trunk lid assembly in the second mode may not be in contact.

[0217] For example, Figure 19Angle 1 shown can be an example of the first threshold. For instance, in a scenario where the trunk lid assembly 20 needs to switch from mode 1 to mode 2, the moment the trunk lid assembly begins the mode switch (i.e., moment 1) can be no earlier than the moment the tailgate opening angle reaches angle 1 (i.e., moment B), as shown... Figure 20 As shown in (b) of the diagram.

[0218] In this embodiment, when the opening angle of the tailgate is greater than or equal to the first threshold, the trunk lid assembly will not interfere with the tailgate even if it is in the second mode. When the opening angle of the tailgate is greater than or equal to the first threshold, the trunk lid assembly is controlled to switch to the second mode. While ensuring that the trunk lid does not interfere with the tailgate, the overall time for tailgate opening and trunk lid assembly switching can also be shortened, thereby saving users' waiting time and improving the user experience.

[0219] In some implementations, the control information can also instruct the tailgate to be closed. Controlling the trunk lid assembly to switch to a target mode may include: when the current mode of the trunk lid assembly is a second mode, controlling the tailgate to close and controlling the trunk lid assembly to switch to a first mode according to the control information.

[0220] In this application, when the current mode of the trunk lid assembly is the second mode and the tailgate needs to be closed, the trunk lid assembly is switched to the first mode according to the control information, and the tailgate is closed. This helps to avoid the failure of the tailgate closing process caused by the trunk lid assembly remaining in the second mode.

[0221] For example, Figure 21 This is a schematic diagram of the mode switching control method for the luggage compartment cover assembly provided in the embodiments of this application.

[0222] Reference Figure 21 Before switching modes, the tailgate can be fully open, and the trunk lid assembly 20 is in mode 2. To avoid the tailgate colliding with the trunk lid assembly during closing, the trunk lid assembly needs to be switched from mode 2 to mode 1.

[0223] For the tailgate, the moment when the tailgate begins to close is denoted as time D, the moment when the tailgate's opening angle decreases to angle 1 is denoted as time E, and the moment when the tailgate reaches the closed state is denoted as time F; time D is earlier than time E, and time E is earlier than time F. For the trunk lid assembly 20, the moment when it begins to switch from mode 2 is denoted as time 4, the moment when the mode switch ends is denoted as time 5, and the moment when the slider stops moving forward during the mode switch is denoted as time 6; time 6 is later than time 4 and earlier than time 5.

[0224] In some embodiments, the tailgate can be controlled to begin closing after the trunk lid assembly is switched to the first mode. For example, as... Figure 21 As shown in (a), time 4 can be earlier than time D, and time 5 can be no later than time D. In this way, when the tailgate begins to close, the cover structure is already in front of the tailgate threshold, which can avoid interference between the two during movement.

[0225] In other embodiments, the tailgate assembly end mode switching can be controlled before the tailgate opening angle reaches angle 1. For example, as Figure 21 As shown in (b), time 5 can be no later than time E. In this mode, regardless of whether the time when the trunk lid assembly 20 begins mode switching (i.e., time 4) is earlier than, later than, or equal to the time when the tailgate begins closing (i.e., time D), the trunk lid assembly is already in the first mode when the tailgate opening angle decreases to angle 1, ensuring that the two do not interfere with each other during movement. Furthermore, at some point between time D and time E, the tailgate closing and the trunk lid assembly mode switching will occur simultaneously. Figure 21 Compared to (a) in the previous method, this method can shorten the overall time required for the tailgate and trunk lid assembly to move, thus reducing the user's waiting time.

[0226] In some other embodiments, the slider can be controlled to stop moving along the guide rail before the tailgate opening angle reaches angle 1. For example, as Figure 21 As shown in (c), time 6 can be no later than time E, and time 5 can be later than time E. That is to say, during the closing process of the tailgate, when the opening angle of the tailgate decreases to angle 1, the slider 22 has moved along the guide rail 21 to the position corresponding to mode 1. At this time, the cover plate structure 23 is already in front of the tailgate threshold. Even if the tailgate continues to close during the subsequent rotation of the cover plate structure, there will be no interference between the tailgate and the trunk cover assembly.

[0227] In some implementations, controlling the trunk lid assembly to switch to the target mode may include: controlling the trunk lid assembly to switch to the first mode before controlling the tailgate to close.

[0228] For example, such as Figure 21 As shown in (a), the trunk lid assembly has switched from mode 2 to mode 1 when the tailgate begins to close.

[0229] In this embodiment, the tailgate is controlled to close after the trunk lid assembly is switched to the first mode. This avoids the tailgate closing failure caused by the mismatch between the tailgate closing speed and the trunk lid assembly mode switching speed, and ensures the normal operation of the tailgate closing process and the trunk lid assembly mode switching process.

[0230] In some implementations, the movement of the tailgate and the mode switching of the trunk lid assembly can occur simultaneously during the second time period. For example, as... Figure 20 As shown in (b), during at least a portion of the time period between time B and time C, the tailgate is in the process of opening, and simultaneously, the trunk lid assembly switches modes. For example, as... Figure 21 As shown in (b), during at least a portion of the time period between time D and time E, the tailgate is in the process of closing, and at the same time, the trunk lid assembly switches modes.

[0231] In this embodiment of the application, the movement of the tailgate and the mode switching of the trunk lid assembly are synchronized during the second time period, which can shorten the overall time required and thus shorten the user's waiting time.

[0232] The above text combines Figures 17 to 21 The methods provided in the embodiments of this application are described in detail below. Figure 23 and Figure 23 This application provides a detailed description of the control device provided in the embodiments. The descriptions of the device embodiments correspond to the descriptions of the method embodiments; therefore, any content not described in detail can be found in the method embodiments above.

[0233] For example, Figure 22 A schematic block diagram of a control device 2000 provided in an embodiment of this application is shown. This device may include modules or units for implementing the methods described in the above embodiments.

[0234] For example, the device may include an acquisition unit 2010 and a control unit 2020. The device 2000 is used to perform... Figure 17 In method 300, the acquisition unit 2010 can be used to execute step S310, and the control unit 2020 can be used to execute step S320.

[0235] Specifically, the acquisition unit 2010 can be used to acquire control information. The control unit 2020 can be used to control the trunk lid assembly to switch to the target mode based on the control information.

[0236] For example, in some implementations, the trunk lid assembly can be in a first mode before mode switching, and the control information can indicate that the target mode is the second mode. The control unit 2020 can be used to: control the lid structure to rotate about the rotation axis in a first direction to a first posture according to the control information; when the lid structure is in the first posture, control the slider to drive the lid structure to move backward along the guide rail; when the lid structure is in the second posture, control the lid structure to rotate about the rotation axis in the opposite direction of the first direction.

[0237] For example, the control information can indicate that the target mode is the second mode, and the control unit 2020 can also be used to control the tailgate to open according to the control information when the current state of the tailgate is closed.

[0238] It should be understood that the division of units in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated.
