Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle trunk technology, and more particularly to a trunk lid assembly, control method, and vehicle. Background Technology
[0002] The trunk, as an important storage space in a car, is usually used to store luggage, tools and other items.
[0003] In related technologies, car trunks typically employ a fixed space design, with their internal structure and volume determined at the time of vehicle manufacture, making it impossible to flexibly adjust the storage space size of the trunk according to actual needs.
[0004] Especially in scenarios involving long-distance travel, transporting large items, or having a lot of luggage, users often need more storage space, and the fixed volume of the suitcase may not be able to meet the demand for more storage space. Summary of the Invention
[0005] This application provides a trunk lid assembly, a control method, and a vehicle, aiming to improve the problem that car trunks with fixed space designs cannot flexibly adjust the storage space size according to actual needs.
[0006] In a first aspect, embodiments of this application provide a luggage lid assembly, including a luggage lid, the luggage lid including a top cover and a tail cover; Along the width direction of the trunk lid, one end of the top cover is rotatably connected to the vehicle body, and the other end of the top cover is movably connected to the tail cover; the tail cover is rotatably connected to the vehicle body. The trunk lid has a closed state relative to the vehicle body and an open state relative to the vehicle body. The top cover has an upward flip-up state spaced apart from the tail cover and a closed return state relative to the tail cover.
[0007] Based on the aforementioned technical means, when the trunk lid is closed, flipping the lid upwards increases the trunk's storage space, allowing for flexible adjustments to accommodate different needs. This is particularly beneficial for long-distance travel, transporting large items, or carrying a large amount of luggage. By keeping the trunk lid closed and adjusting the flip-up angle to the maximum, the trunk's storage space is maximized to meet the storage requirements of these scenarios. Furthermore, when the trunk lid is closed, flipping it upwards or returning it to its original position alters the vehicle's appearance, enhancing its visual appeal.
[0008] Optionally, along the width direction of the trunk lid, one end of the top cover is hinged to the vehicle body, and the other end of the top cover is movably connected to the tail cover via a first driving member. The first driving member is used to drive the top cover to rotate and to support the top cover when the top cover is in the flipped-up state.
[0009] Based on the above-mentioned technical means, the top cover can be electrically controlled to flip up, and when the top cover is in the flipped state, it can be supported to keep the top cover in a stable flipped state.
[0010] Optionally, the trunk lid assembly further includes a support rod, one end of which is hinged to the tailgate body, and the other end of which is hinged to the vehicle body; And / or, the trunk lid assembly further includes a second drive member connected to the tail cover body, the second drive member being used to drive the trunk lid to rotate and to support the trunk lid when the trunk lid is in the open state.
[0011] Based on the above-mentioned technical means, the opening of the trunk lid can be electrically controlled, and the trunk lid can be supported when it is open, so as to keep the trunk lid in a stable open state.
[0012] Optionally, the trunk lid assembly further includes a flexible seal, which is connected to the top cover, the support rod, and the tail cover. When the top cover is in the flipped-up state, the flexible seal is used to seal the gap between the top cover and the support rod and the gap between the top cover and the tail cover.
[0013] The aforementioned technical means can prevent items from falling out of the suitcase, prevent rainwater from entering the suitcase, and ensure the suitcase's aesthetic appearance.
[0014] Optionally, the luggage compartment lid assembly further includes a first locking mechanism, which is used to lock the top cover and the tail cover when the top cover is in the returned state. And / or, the trunk lid assembly further includes a second locking mechanism, which, when the trunk lid is in the closed state, locks the trunk lid to the vehicle body.
[0015] According to the above technical means, the first locking mechanism can keep the top cover in the returned state, preventing the top cover from accidentally flipping up due to vibration, bumps or external forces during vehicle operation; the second locking mechanism can keep the trunk lid in the closed state, preventing the trunk lid from accidentally opening due to vibration, bumps or external forces during vehicle operation.
[0016] Secondly, embodiments of this application provide a luggage lid assembly control method, applied to the luggage lid assembly described above; The luggage compartment lid assembly control method includes: Receive luggage lid control commands and control the luggage lid to open or close according to the luggage lid control commands; Receive the top cover control command, and control the top cover to flip up or return to its original position according to the top cover control command.
[0017] Based on the aforementioned technical means, when the suitcase lid is closed, the top cover can be flipped up to increase the suitcase's storage space, thus allowing for flexible expansion of the storage space according to actual needs. Furthermore, based on control commands, the suitcase lid can be automatically opened or closed, and the top cover can be automatically flipped up or returned to its original position.
[0018] Optionally, the luggage compartment lid assembly includes a first driving member for driving the top cover to rotate. When controlling the top cover to flip up or return to its original position, a first driving parameter is determined according to the opening degree of the luggage compartment lid, and the first driving member is controlled to operate according to the first driving parameter. And / or, the trunk lid assembly includes a second drive member for driving the trunk lid to rotate, and when controlling the trunk lid to open or close, a second drive parameter is determined according to the upward tilt angle of the top cover, and the operation of the second drive member is controlled according to the second drive parameter.
[0019] Based on the above technical means, the second driving parameter is associated with the upward tilt angle of the top cover. The second driving parameter can be adjusted based on different tilt angles, so that the opening and closing process of the trunk lid is more stable and reliable, avoiding structural deformation, wear or damage caused by excessive opening or closing speed and excessive driving force.
[0020] By linking the first driving parameter to the opening degree of the trunk lid, the first driving parameter can be adjusted based on different opening degrees, thereby making the process of the lid flipping up and returning to its original position more stable and reliable, and avoiding structural deformation, wear or damage caused by excessive flipping or returning speed and excessive driving force.
[0021] Optionally, when the top cover is in the returned state, the maximum opening of the trunk lid is the second maximum opening. When controlling the opening of the trunk lid or controlling the top cover to flip up, the sum of the opening degree of the trunk lid and the flipping angle of the top cover is less than or equal to the second maximum opening degree.
[0022] Based on the above technical means, by limiting the sum of the opening of the trunk lid and the upward tilt angle of the top cover to no more than the second maximum opening allowed by the structure, the trunk lid will not exceed the range of movement allowed by the structure during the opening process or the top cover during the upward tilting process, thereby avoiding interference, collision, structural damage, etc.
[0023] Optionally, controlling the opening or closing of the trunk lid according to the trunk lid control command includes: If the luggage lid control command is a luggage lid opening command, then the upward tilt angle of the top cover and the opening degree of the luggage lid are obtained; If the upward tilt angle of the top cover is greater than 0, and the sum of the opening degree of the trunk lid and the upward tilt angle of the top cover is less than the second maximum opening degree, then the upward tilt angle of the top cover remains unchanged, and the trunk lid is controlled to open until the opening degree of the trunk lid reaches the difference between the second maximum opening degree and the upward tilt angle of the top cover.
[0024] According to the above technical means, when the sum of the current opening degree of the trunk lid and the upward tilt angle of the top cover is less than the second maximum opening degree allowed by the structure, the upward tilt angle of the top cover remains unchanged during the opening of the trunk lid, that is, the relative stillness of the top cover and the tail cover is maintained. There is no need to adjust the above-mentioned second driving parameter according to the change of the upward tilt angle of the top cover, which helps to simplify the control process.
[0025] Optionally, when the trunk lid is in the closed state, the maximum upward tilt angle of the top cover is taken as the first maximum opening, and the difference between the second maximum opening and the first maximum opening is taken as the maximum opening difference; The step of controlling the top cover to flip up or return to its original position according to the top cover control command includes: If the control command for the top cover is a command to flip the top cover up, then the opening degree of the trunk lid is obtained; If the opening of the trunk lid is greater than the maximum opening difference, the top cover is controlled to flip up until the flipping angle of the top cover reaches the difference between the second maximum opening and the opening of the trunk lid. If the opening degree of the luggage compartment lid is less than or equal to the maximum opening degree difference, then the top cover is controlled to flip up until the flipping angle of the top cover reaches the first maximum opening degree.
[0026] Based on the aforementioned technical means, when the top cover is flipped up, it flips up to the maximum angle that the structure allows, so as to maximize the storage space of the suitcase.
[0027] Optionally, when the trunk lid is in the closed state, the maximum upward tilt angle of the top cover is the first maximum opening angle; The step of controlling the opening or closing of the trunk lid according to the trunk lid control command includes: If the luggage lid control command is a luggage lid closing command, then obtain the upward tilt angle of the top cover; If the upward tilt angle of the top cover is less than the first maximum opening, then control the top cover to tilt upward until the upward tilt angle of the top cover is equal to the first maximum opening, and at the same time control the trunk lid to close until the opening of the trunk lid is 0. If the upward tilt angle of the top cover is equal to the first maximum opening angle, then the upward tilt angle of the top cover remains unchanged, and the luggage compartment lid is controlled to close.
[0028] Based on the above-mentioned technical means, when the opening degree of the suitcase lid reaches 0, the upward angle of the top cover can reach the first maximum opening degree, thereby preventing the items inside the suitcase from being unexpectedly squeezed when the suitcase lid is closed, and thus preventing damage to the items inside the suitcase.

[0032] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0033] Firstly, referring to Figure 1 and Figure 2 This application provides a trunk lid assembly for use in a vehicle. The trunk lid assembly includes a trunk lid 10, which includes a top cover 11 and a rear cover 12. Along the width direction of the trunk lid 10, one end of the top cover 11 is rotatably connected to the vehicle body 60, and the other end of the top cover 11 is movably connected to the rear cover 12. The rear cover 12 is rotatably connected to the vehicle body 60. The trunk lid 10 has a closed state relative to the vehicle body 60 and an open state relative to the vehicle body 60. The top cover 11 has an upward-flipped state spaced apart from the rear cover 12 and a closed return state relative to the rear cover 12.
[0034] The width of the trunk lid 10 is consistent with the length of the vehicle. The width of the trunk lid 10 can be seen from the X direction in the figure. The length of the trunk lid 10 is consistent with the width of the vehicle.
[0035] The trunk lid 10 closes relative to the body 60, and the trunk lid 10 is attached to the body 60 to close the trunk opening. Figure 1 , Figure 2 , Figure 4 and Figure 5In the middle position, the trunk lid 10 is closed, and the trunk opening is not exposed. When the trunk lid 10 is open relative to the vehicle body 60, a clear gap is formed between the trunk lid 10 and the vehicle body 60. When the trunk lid 10 is open, at least a portion of the trunk opening is exposed.
[0036] The opening degree A2 of the trunk lid 10 indicates the degree to which the trunk lid 10 is open, referring to the angle of rotation around the axis of rotation when it is open. Specifically, the opening degree A2 of the trunk lid 10 refers to the angle of rotation of the tail cover body 12 around the axis of rotation when it is open. When the trunk lid 10 is in the closed state, the opening degree A2 of the trunk lid 10 is 0. When the top cover body 11 is in the returned state, the maximum opening degree of the trunk lid 10 is the second maximum opening degree A2max. When the trunk lid 10 is in the open state, the opening degree of the trunk lid 10 can be equal to A2max or less than A2max.
[0037] The top cover 11 is closed relative to the tail cover 12, and the tail end of the top cover 11 is attached to the tail cover 12, with no obvious gap between the top cover 11 and the tail cover 12. Figure 1 and Figure 4 In the middle, the top cover 11 is in the returned position. Figure 2 and Figure 5 In the middle, the top cover 11 is in an upturned state, and a clear gap is formed between the top cover 11 and the tail cover 12.
[0038] Figure 1 and Figure 4 In the case of a luggage compartment, the trunk lid 10 is in the closed state, and the top cover 11 is in the returned state. At this time, the luggage compartment lid 10 includes a sloping part that is higher in the front and lower in the back, and a tail structure formed by bending at the tail end of the sloping part, so that the luggage compartment lid 10 has a zigzag shape. The interface F1 between the top cover 11 and the tail cover 12 can be horizontal, and it passes through the step formed in the X direction at the upper end of the tail of the luggage compartment lid 10.
[0039] Figure 2 and Figure 5 In the middle, the trunk lid 10 is in the closed state, and the top cover 11 is in the flip-up state. At this time, the trunk lid 10 is in a "-shaped" position. The vehicle body 60 is connected to a luggage compartment carpet, and along the height direction of the luggage compartment cover 10, the top cover 11 is opposite to the luggage compartment carpet.
[0040] The upward tilt angle A1 of the top cover 11 indicates the degree of tilting of the top cover 11, referring to the angle of rotation around the axis of rotation when tilted upwards. Specifically, the upward tilt angle A1 of the top cover 11 refers to the angle of rotation of the tail cover 12 around the axis of rotation when opened. When the trunk lid 10 is in the closed state, the maximum upward tilt angle of the top cover 11 is the first maximum opening angle A1max. When the top cover 11 is in the returned state, the upward tilt angle A1 of the top cover 11 is 0. When the top cover 11 is in the tilted state, the upward tilt angle A1 of the top cover 11 can be equal to A1max or less than A1max. A1max is less than A2max.
[0041] It should be noted that during the opening or closing of the trunk lid 10, the trunk lid 10 rotates as a whole around the rotation axis. During this whole rotation, the top cover 11 and the tail cover 12 remain relatively stationary, or the top cover 11 moves relative to the tail cover 12.
[0042] In the embodiments of this application, reference is made to Figure 3 When the suitcase lid 10 is closed, the top cover 11 can be flipped up to increase the suitcase's storage space, allowing for flexible expansion of the storage space according to actual needs. Especially in scenarios involving long-distance travel, transporting large items, or carrying a lot of luggage, keeping the suitcase lid 10 closed and adjusting the flip angle A1 of the top cover 11 to the first maximum opening angle A1max maximizes the suitcase's storage space to meet the storage needs of these scenarios.
[0043] For luggage compartments with a fixed space design, the vehicle's appearance is monotonous when the luggage compartment is closed. In this embodiment, when the luggage compartment lid 10 is closed, the vehicle's appearance can be altered by flipping the top cover 11 upwards or returning it to its original position, thus enhancing its visual appeal. For example, when the luggage compartment lid 10 is closed and the top cover 11 is in its original position, the vehicle's appearance can be that of a fastback sedan; when the luggage compartment lid 10 is closed and the top cover 11 is flipped upwards, the vehicle's appearance can be that of a shooting brake.
[0044] Reference Figure 8 In other embodiments, the interface F1 between the top cover 11 and the tail cover 12 may be inclined and pass through the inner bend of the luggage compartment cover 10, which has a zigzag shape.
[0045] In some embodiments, refer to Figure 2 Along the width direction of the trunk lid 10, one end of the top cover 11 is hinged to the vehicle body 60, and the other end of the top cover 11 is movably connected to the tail cover 12 through the first drive member 30. The first drive member 30 is used to drive the top cover 11 to rotate and to support the top cover 11 when the top cover 11 is in the flipped-up state.
[0046] One end of the top cover 11 is specifically hinged to the body 60 via a hinge structure, and the hinge point is... Figure 2 At point R1, the axis of rotation around which the top cover 11 rotates passes through point R1 and extends along the length of the trunk lid 10. There is at least one first driving member 30. The first driving member 30 is one of an electric strut, a cylinder, or an electric cylinder. Preferably, the first driving member 30 is an electric strut. In this embodiment, the first driving member 30 can electrically control the top cover 11 to flip upwards, and supports the top cover 11 when it is in the flipped-up state, thereby maintaining the top cover 11 in a stable flipped-up state.
[0047] In some embodiments, refer to Figure 2 The trunk lid assembly also includes a support rod 20, one end of which is hinged to the tail cover body 12, and the other end of which is hinged to the vehicle body 60. The trunk lid assembly also includes a second drive member 40 connected to the tail cover body 12. The second drive member 40 is used to drive the trunk lid 10 to rotate and to support the trunk lid 10 when the trunk lid 10 is in the open state.
[0048] The other end of the support rod 20 is specifically hinged to the body 60 via a hinge structure, and the hinge point is... Figure 2 At point R1, the axis of rotation around which the trunk lid 10 rotates passes through point R1 and extends along the length of the trunk lid 10. There can be two support rods 20, located on opposite sides of the trunk lid assembly along its length. When the trunk lid 10 is open, the angle of rotation of the tail cover body 12 around the axis of rotation is equal to the angle of rotation of the support rods 20. The angle of rotation of the support rods 20 can be taken as the opening degree A2 of the trunk lid 10.
[0049] The number of second driving components 40 is at least one. The second driving component 40 is one of an electric strut, a cylinder, or an electric cylinder. Preferably, the second driving component 40 is an electric strut. In this embodiment, the second driving component 40 can electrically control the opening of the trunk lid 10, and support the trunk lid 10 when it is in the open state, thereby keeping the trunk lid 10 in a stable open state.
[0050] In some embodiments, refer to Figure 2 The luggage compartment lid assembly also includes a flexible seal 50, which is connected to the top cover 11, the support rod 20 and the tail cover 12. When the top cover 11 is in the flip-up state, the flexible seal 50 is used to seal the gap between the top cover 11 and the support rod 20 and the gap between the top cover 11 and the tail cover 12.
[0051] The flexible seal 50 is a fabric, such as carbon fiber cloth or polyester fiber cloth. When the top cover 11 is flipped up, the flexible seal 50 gradually unfolds to seal the gap between the top cover 11 and the support rod 20, as well as the gap between the top cover 11 and the tail cover 12. The flexible seal 50 prevents items from falling out of the suitcase, avoids rainwater entering the suitcase, and maintains an aesthetically pleasing appearance.
[0052] In some embodiments, the trunk lid assembly further includes a first locking mechanism, which locks the top cover 11 and the tail cover 12 when the top cover 11 is in the returned state; the trunk lid assembly also includes a second locking mechanism, which locks the trunk lid 10 and the vehicle body 60 when the trunk lid 10 is in the closed state. The first locking mechanism and the second locking mechanism can be mechanical locks or electronic locks.
[0053] The first locking mechanism may include a first lock body disposed on the top cover 11 and a first latch disposed on the tail cover 12. The first lock body and the first latch cooperate to lock the top cover 11 and the tail cover 12. The first lock body may be disposed on the top cover 11 and the tail cover 12. Figure 2 The R2 position is located in the middle. The first locking mechanism can keep the top cover 11 in the returned state, preventing the top cover 11 from accidentally flipping up due to vibration, bumps or external forces during vehicle operation.
[0054] The second locking mechanism may include a second lock body disposed on the tailgate 12 and a second latch disposed on the vehicle body 60. The second lock body and the second latch cooperate to lock the trunk lid 10 to the vehicle body 60. The second lock body may be disposed on the tailgate 12. Figure 2 The R3 position is located in the middle. The second locking mechanism can keep the trunk lid 10 closed, preventing the trunk lid 10 from being accidentally opened due to vibration, bumps or external forces during vehicle operation.
[0055] Reference Figure 6 As an example, when the trunk lid 10 is closed, the top cover 11 is in the returned position; then, the trunk lid 10 is opened. During the opening process, the top cover 11 and the tail cover 12 remain relatively stationary. The trunk lid 10 is opened until the opening degree A2 reaches A2max.
[0056] Reference Figure 7As another example, in stage T1, the trunk lid 10 is closed, the top cover 11 is flipped up, and the flipping angle A1 is equal to A1max. Then, the trunk lid 10 is opened. During the opening process, the flipping angle A1 of the top cover 11 remains unchanged, and the top cover 11 and the tail cover 12 remain relatively stationary. The trunk lid 10 is opened until the opening degree A2 reaches the difference between A2max and A1max. At this time, it is in stage T2. After that, if it is necessary to open the trunk lid 10 again, the top cover 11 is returned to its original position until the flipping angle A1 reaches 0. At the same time, the trunk lid 10 is opened until the opening degree A2 reaches A2max. After the opening is completed, it is in stage T3.
[0057] Secondly, embodiments of this application provide a luggage lid assembly control method, applied to the aforementioned luggage lid assembly.
[0058] Reference Figure 9 The luggage compartment lid assembly control method includes: S101, receiving a luggage compartment lid control command and controlling the luggage compartment lid to open or close according to the luggage compartment lid control command; S102, receiving a top cover body control command and controlling the top cover body to flip up or return to its original position according to the top cover body control command.
[0059] The trunk lid control commands and top cover control commands can be triggered by a touch-sensitive virtual button, by pressing a physical button, or by voice. The trunk lid assembly includes a first drive member 30 for driving the top cover 11 to rotate and a second drive member 40 for driving the trunk lid 10 to rotate. Controlling the trunk lid to open or close according to the trunk lid control commands includes: controlling the second drive member to operate according to the trunk lid control commands, thereby controlling the trunk lid to open or close. Controlling the top cover to flip up or return to its original position according to the top cover control commands includes: controlling the first drive member to operate according to the top cover control commands, thereby controlling the top cover to flip up or return to its original position.
[0060] When opening the trunk lid 10, the second locking mechanism must be unlocked before the second drive component 40 is operated. When flipping the top cover 11 upwards, the first locking mechanism must be unlocked before the first drive component 30 is operated.
[0061] In the embodiments of this application, reference is made to Figure 3 When the luggage lid 10 is closed, the top cover 11 can be flipped up to increase the luggage's storage space, thus allowing for flexible expansion of the luggage's storage space according to actual needs. In addition, based on control commands, the luggage lid 10 can be automatically controlled to open or close, and the top cover 11 can be automatically controlled to flip up or return to its original position.
[0062] In some embodiments, the user can configure whether to disable the flip-up function of the top cover 11 through the host interface. If the user chooses to disable the flip-up function of the top cover 11, the first drive unit 30 and the first locking mechanism will not respond to any operation commands. At this time, the control logic of the luggage compartment lid is the same as that of a normal luggage compartment lid.
[0063] In some embodiments, the trunk lid assembly includes a first drive member 30 for driving the top cover 11 to rotate. When the top cover 11 is controlled to flip up or return to its original position, a first drive parameter is determined according to the opening angle A2 of the trunk lid 10, and the first drive member 30 is controlled to operate according to the first drive parameter. The trunk lid assembly also includes a second drive member 40 for driving the trunk lid 10 to rotate. When the trunk lid 10 is controlled to open or close, a second drive parameter is determined according to the flip angle A1 of the top cover 11, and the second drive member 40 is controlled to operate according to the second drive parameter.
[0064] The opening degree A2 of the trunk lid 10 indicates the degree to which the trunk lid 10 is open, referring to the angle of rotation around the axis of rotation when it is open. Specifically, the opening degree A2 of the trunk lid 10 refers to the angle of rotation of the tail cover body 12 around the axis of rotation when it is open. When the trunk lid 10 is in the closed state, the opening degree A2 of the trunk lid 10 is 0.
[0065] The upward tilt angle A1 of the top cover 11 indicates the degree of tilting of the top cover 11, referring to the angle of rotation around the axis of rotation when tilted upwards. Specifically, the upward tilt angle A1 of the top cover 11 refers to the angle of rotation of the tail cover 12 around the axis of rotation when opened. When the top cover 11 is in the returned state, the upward tilt angle A1 of the top cover 11 is 0. With the trunk lid 10 in the closed state, the maximum upward tilt angle of the top cover 11 is the first maximum opening A1max, and with the top cover 11 in the returned state, the maximum opening of the trunk lid 10 is the second maximum opening A2max, where A1max is less than A2max.
[0066] The first driving parameter is determined based on the opening degree of the trunk lid 10, including: determining the first driving parameter based on the correspondence between the opening degree A2 of the trunk lid 10, the opening degree range of the trunk lid 10, and the first driving parameter. The correspondence between the opening degree range of the trunk lid 10 and the first driving parameter is pre-calibrated. For example, A2max is divided into multiple opening degree ranges according to a step size of X2, and the first driving parameter corresponding to each opening degree range is pre-calibrated. X2 can be set according to actual needs, such as 5°, 10°, 15°, etc.
[0067] During the upward movement of the top cover 11, the first driving parameters may include the pushing force of the first driving member 30 on the top cover 11 and the extension speed of the first driving member 30. During the downward movement of the top cover 11, the first driving parameters may include the pulling force of the first driving member 30 on the top cover 11 and the retraction speed of the first driving member 30.
[0068] The second driving parameter is determined based on the upward tilting angle A1 of the top cover 11, including: determining the second driving parameter based on the upward tilting angle A1 of the top cover 11, the correspondence between the upward tilting angle range of the top cover 11 and the second driving parameter. The correspondence between the upward tilting angle range of the top cover 11 and the second driving parameter is pre-calibrated. For example, A1max is divided into multiple opening ranges according to a step size X1, and the second driving parameter corresponding to each opening range is pre-calibrated. X1 can be set according to actual needs, such as 3°, 5°, etc.
[0069] During the opening of the trunk lid 10, the second driving parameters may include the pushing force of the second driving member 40 on the tail cover body 12 and the extension speed of the second driving member 40. During the closing of the trunk lid 10, the second driving parameters may include the pulling force of the second driving member 40 on the trunk lid 10 and the retraction speed of the second driving member 40.
[0070] The upward tilt angle A1 of the top cover 11 affects the center of gravity of the trunk lid 10 itself. By associating the second driving parameter with the upward tilt angle A1 of the top cover 11, the second driving parameter can be adjusted based on different tilt angles A1, thereby making the opening and closing process of the trunk lid 10 more stable and reliable, and avoiding structural deformation, wear or damage caused by excessive opening or closing speed and excessive driving force.
[0071] The opening degree A2 of the trunk lid 10 will affect the position of the center of gravity of the trunk lid 10 relative to the vehicle body 60. By associating the first driving parameter with the opening degree A2 of the trunk lid 10, the first driving parameter can be adjusted based on different opening degrees A2, so that the process of flipping up and returning the top cover 11 is more stable and reliable, and structural deformation, wear or damage caused by excessively fast flipping or returning speed and excessive driving force is avoided.
[0072] In some embodiments, when the trunk lid 10 is opened or the top cover 11 is flipped up, the sum of the opening degree A2 of the trunk lid 10 and the flipping angle A1 of the top cover 11 is less than or equal to the second maximum opening degree A2max.
[0073] Due to structural limitations, the sum of the opening angle A2 of the trunk lid 10 and the upward tilting angle A1 of the top cover 11 must be less than or equal to the second maximum opening angle A2max. In this embodiment, by limiting the sum of the opening angle A2 of the trunk lid 10 and the upward tilting angle A1 of the top cover 11 to no more than the second maximum opening angle A2max allowed by the structure, the trunk lid 10 will not exceed the range of movement allowed by the structure during opening or the top cover 11 will not exceed the range of movement allowed by the structure during tilting, thereby avoiding interference, collision, structural damage, etc.
[0074] In some embodiments, refer to Figure 10 Controlling the opening and closing of the trunk lid according to the trunk lid control command includes: S201, If the luggage lid control command is a luggage lid opening command, then obtain the upward tilt angle of the top cover and the opening degree of the luggage lid; S202, if the upward tilt angle of the top cover is greater than 0, and the sum of the opening of the trunk lid and the upward tilt angle of the top cover is less than the second maximum opening, then keep the upward tilt angle of the top cover unchanged and control the opening of the trunk lid until the opening of the trunk lid reaches the difference between the second maximum opening and the upward tilt angle of the top cover.
[0075] In S201, the current flip-up angle A1 of the top cover 11 and the opening degree A2 of the trunk lid 10 are obtained. In S202, if the flip-up angle A1 of the top cover 11 is greater than 0, it indicates that the top cover 11 has flipped up to a certain extent. If the sum of the opening degree A2 of the trunk lid 10 and the flip-up angle A1 of the top cover 11 is less than the second maximum opening degree A2max, it indicates that the trunk lid 10 still has some opening margin if the top cover 11 does not return to its original position. In S202, during the opening process of the trunk lid 10, the opening degree A2 of the trunk lid 10 is updated in real time. The opening ends when the opening degree A2 of the trunk lid 10 reaches the difference between the second maximum opening degree A2max and the flip-up angle A1 of the top cover. In S202, when calculating the difference between the second maximum opening degree A2max and the flip-up angle A1 of the top cover, the flip-up angle A1 of the top cover refers to the aforementioned constant flip-up angle A1.
[0076] In this embodiment, when the sum of the opening angle A2 of the current trunk lid 10 and the upward tilt angle A1 of the top cover 11 is less than the second maximum opening angle A2max allowed by the structure, the upward tilt angle A1 of the top cover 11 remains unchanged during the opening of the trunk lid 10, that is, the relative stationary position of the top cover 11 and the tail cover 12 is maintained. There is no need to adjust the above-mentioned second driving parameter according to the change of the upward tilt angle A1 of the top cover 11, which helps to simplify the control process.
[0077] Following S202, it also includes: S203, if the luggage compartment lid opening command is received again, the top cover is controlled to return to its original position until the upward angle of the top cover reaches 0, and the luggage compartment lid is controlled to open until the opening degree of the luggage compartment lid reaches the second maximum opening degree.
[0078] During the process of the top cover 11 returning to its original position and the trunk lid 10 opening, the upward tilt angle A1 of the top cover 11 and the opening degree A2 of the trunk lid 10 change in real time. During this process, the second driving parameter needs to be adjusted accordingly based on the change in the upward tilt angle A1 of the top cover 11, and the first driving parameter needs to be adjusted accordingly based on the change in the opening degree A2 of the trunk lid 10.
[0079] Specifically, an example of S202 is as follows: (Refer to...) Figure 7In stage T1, the trunk lid 10 is closed, meaning the opening angle A2 is 0. The top cover 11 is flipped up, and the flip angle A1 equals A1max, while the sum of A1max and A2 is less than A2max. Then, the trunk lid 10 opens. During the opening process, the flip angle A1 of the top cover 11 remains unchanged, and the top cover 11 and the tail cover 12 remain relatively stationary. The trunk lid 10 opens until the opening angle A2 reaches the difference between A2max and A1max, at which point stage T2 begins. An example of S203 is as follows: (Refer to...) Figure 7 After stage T2, if the luggage compartment lid 10 needs to continue to open, the top cover 11 is returned to its original position until the upward angle A1 reaches 0, and the luggage compartment lid 10 is opened until the opening degree A2 reaches A2max. After the opening is completed, it enters stage T3.
[0080] In some embodiments, refer to Figure 10 S201, if the luggage compartment lid control command is a luggage compartment lid opening command, then after obtaining the upward tilt angle of the top cover and the opening degree of the luggage compartment lid, it also includes: S204, if the upward tilt angle of the top cover is 0, then control the trunk lid to open until the trunk lid reaches the second maximum opening angle; S205, if the upward tilt angle of the top cover is greater than 0, and the sum of the opening of the trunk lid and the upward tilt angle of the top cover is equal to the second maximum opening, then control the top cover to return to its original position until the upward tilt angle of the top cover reaches 0, and simultaneously control the trunk lid to open until the opening of the trunk lid reaches the second maximum opening.
[0081] In S204, when the upward tilt angle A1 of the top cover 11 is 0, it indicates that the top cover 11 is in the returned position. At this time, the opening degree A2 of the trunk lid 10 can reach the second maximum opening degree A2max. An example of S204 can be found here. Figure 6 .
[0082] In S205, the sum of the opening degree A2 of the trunk lid 10 and the upward flip angle A1 of the top cover 11 is equal to the second maximum opening degree A2max. This means that if the top cover 11 does not return to its original position, the trunk lid 10 has no opening margin. At this time, the top cover 11 needs to be controlled to return to its original position in order to open the trunk lid 10.
[0083] In some embodiments, refer to Figure 11 When the trunk lid 10 is in the closed state, the maximum upward tilt angle of the top cover 11 is the first maximum opening angle A1max, and the difference between the second maximum opening angle A2max and the first maximum opening angle A1max is the maximum opening angle difference. Controlling the top cover to flip up or return to its original position according to the top cover control command includes: S301, if the top cover control command is a top cover flip command, then obtain the opening degree of the trunk lid; S302, if the opening of the trunk lid is greater than the maximum opening difference, control the top cover to flip up until the flip angle of the top cover reaches the difference between the second maximum opening and the opening of the trunk lid. S303, if the opening degree of the trunk lid is less than or equal to the maximum opening degree difference, control the top cover to flip up until the flipping angle of the top cover reaches the first maximum opening degree.
[0084] In S301, the current opening degree A2 of the trunk lid 10 is obtained. In S302, if the opening degree A2 of the trunk lid 10 is greater than the maximum opening degree difference, it means that the top cover 11 cannot be opened to the first maximum opening degree A1max, and can only be opened to the difference between the second maximum opening degree A2max and the opening degree A2 of the trunk lid 10. In S303, if the opening degree A2 of the trunk lid 10 is less than or equal to the maximum opening degree difference, it means that the top cover 11 can be opened to the first maximum opening degree A1max. In S302 and S303, the opening degree A2 of the trunk lid 10 is the same as the A2 obtained in S301.
[0085] In this embodiment, when the top cover 11 is flipped up, it flips up to the maximum angle that the structure allows, so as to maximize the storage space of the suitcase.
[0086] In some embodiments, refer to Figure 12 When the trunk lid 10 is closed, the maximum upward opening angle of the top cover 11 is the first maximum opening angle A1max; Controlling the opening and closing of the trunk lid according to the trunk lid control commands includes: S401, if the luggage compartment lid control command is a luggage compartment lid closing command, then obtain the upward tilt angle of the top cover; S402, if the upward tilt angle of the top cover is less than the first maximum opening, control the top cover to tilt upward and control the trunk lid to close simultaneously until the upward tilt angle of the top cover is equal to the first maximum opening and the trunk lid opening is 0. S403, if the upward tilt angle of the top cover is equal to the first maximum opening angle, then keep the upward tilt angle of the top cover unchanged and control the trunk lid to close.
[0087] In S401, the current flip-up angle A1 of the top cover 11 is obtained. In S402, during the flip-up of the top cover 11 and the closing of the trunk lid 10, the opening degree A2 of the trunk lid 10 and the flip-up angle A1 of the top cover 11 change in real time. It is necessary to control that the sum of the real-time changing opening degree A2 of the trunk lid 10 and the flip-up angle A1 of the top cover 11 is less than or equal to the second maximum opening degree A2max. Furthermore, it is necessary to adjust the aforementioned second driving parameter accordingly based on the change of the flip-up angle A1 of the top cover 11, and to adjust the aforementioned first driving parameter accordingly based on the change of the opening degree A2 of the trunk lid 10.
[0088] In this embodiment of the application, when the opening degree A2 of the luggage lid 10 reaches 0, the upward opening angle A1 of the top cover 11 can reach the first maximum opening degree A1max, thereby preventing the items inside the luggage from being unexpectedly squeezed when the luggage lid 10 is closed, and thus preventing damage to the items inside the luggage.
[0089] In some embodiments, refer to Figure 13 The top cover is controlled to flip up or return to its original position according to the control command of the top cover, including: S501, if the top cover control command is the top cover return command, the voice prompt will say "Please confirm that there is enough space in the luggage compartment and request the top cover to return to its original position again". S502, if the top cover body return command is received again, the top cover body is controlled to return to its original position.
[0090] In this embodiment, the user can be reminded to check whether the top cover 11 will squeeze the items inside the suitcase when it returns to its original position, thereby avoiding damage to the items inside the suitcase.
