[0054] Convertible vehicles, due to their unique driving experience and fashionable appearance design, meet the current requirements of drivers for vehicle personalization and diversification. The roof of a convertible vehicle can be flexibly opened and closed according to the driver's needs, bringing more rich driving pleasures to the driver. There is a linkage mechanism in the convertible vehicle for driving the roof to switch between the open and closed states. After the roof is opened, the linkage mechanism for driving and controlling the opening and closing of the soft top will be exposed outside. These linkages are usually made of metal materials, and their appearance is relatively rigid and obtrusive, forming a sharp contrast with the overall smooth and elegant body lines of the convertible vehicle, greatly affecting the aesthetics of the vehicle. To solve the problem that the exposed linkages affect the aesthetics, some covering devices have emerged in the related art. However, the existing covering devices usually require a large movement envelope during the movement process. In the limited body space, this large movement envelope is likely to cause interference between the covering device and other components of the vehicle. For example, the covering device may collide or rub against the sheet metal structure, electrical wiring, interior components, etc. of the vehicle body during the movement process, which will not only affect the normal movement and function realization of the covering device itself, but also may damage other components of the vehicle, increasing the maintenance cost and use risk of the vehicle, and reducing the safety and reliability of the convertible vehicle.

[0055] For the above reasons, the embodiments of the present application provide a convertible link covering device, which can be installed on the convertible storage cover of a vehicle. Through this convertible link covering device, on the one hand, it can effectively cover the link when the roof is opened to improve the overall appearance of the vehicle. On the other hand, the convertible link covering device provided by the embodiments of the present application realizes the covering of the link and the removal of the covering of the link outlet through a telescopic mechanism. This telescopic structure has a smaller movement envelope, thus being less likely to cause the above interference problem, ensuring the realization of functions and avoiding the impact on the structural safety of other components.

[0056] The following will describe in detail the convertible link covering device provided by the present application with reference to the accompanying drawings and specific embodiments. In the embodiments of the present application, as Figure 5 shown, the first direction X is the length direction of the vehicle, the second direction Y is the width direction of the vehicle, and the third direction Z is the height direction of the vehicle.

[0057] As Figure 2 shown, the convertible link covering device provided by the embodiments of the present application may specifically include: a telescopic mechanism 100 and a decorative cover assembly 200. Among them, the telescopic mechanism 100 includes a first guide rail 10 and a first guide wheel assembly 20. The first guide wheel assembly 20 is connected to the first guide rail 10 and can move along the first guide rail 10. The decorative cover assembly 200 is connected to the first guide wheel assembly 20 to move with the first guide wheel assembly 20 and switch between the extended state and the retracted state; as Figure 4 shown, a schematic diagram of the switching between the extended state and the retracted state of the decorative cover assembly 200 is shown. Among them, in the extended state, the decorative cover assembly 200 extends out of the first guide rail 10 and covers the outlet of the convertible link 301. In the retracted state, the decorative cover assembly 200 retracts into the first guide rail 10 and removes the covering of the outlet of the convertible link 301. In practical applications, the telescopic mechanism 100 is connected to the decorative cover assembly 200 and is used to drive the decorative cover assembly 200 to complete the telescopic movement, so that the decorative cover assembly 200 can switch between the extended state and the retracted state. The decorative cover assembly 200, as part of the interior and exterior decoration, can cover the outlet of the convertible link 301 in the extended state, thus ensuring the aesthetic appearance of the vehicle after the roof is opened.

[0058] Specifically, the telescopic mechanism 100 is disposed below the convertible storage cover 302 along the vehicle height direction and fixedly connected to the convertible storage cover 302, ensuring that the entire convertible link covering device can be stably connected to the convertible storage cover 302. Among them, the convertible storage cover 302 is located at the rear of the vehicle and is used to close the convertible storage compartment of the vehicle roof. When the telescopic mechanism 100 is stably connected to the convertible storage cover 302, its position can be kept fixed, thereby providing a stable supporting effect for the telescopic movement of the trim cover assembly 200. Optionally, the telescopic mechanism 100 further includes a first connecting plate 70, the first connecting plate 70 is connected to the first guide rail 10, the first connecting plate 70 is used to connect to the convertible storage cover 302, and the telescopic mechanism 100 is fixed to the convertible storage cover 302 through the first connecting plate 70 to ensure the position stability of the first guide rail 10.

[0059] The telescopic mechanism 100 includes a first guide rail 10 and a first guide wheel assembly 20. The length direction of the first guide rail 10 is generally set along the vehicle length direction. The first guide wheel assembly 20 is movably connected to the first guide rail 10 along the length direction of the first guide rail 10, so that a displacement along the vehicle length direction can be generated. The trim cover assembly 200 is connected to the first guide wheel assembly 20. During the process of the first guide wheel assembly 20 moving along the vehicle length direction, the trim cover assembly 200 generates a synchronous movement with the first guide wheel assembly 20, thereby realizing the switching between the extended state and the retracted state. In practical applications, the first guide wheel assembly 20 can slide or roll relative to the first guide rail 10 to generate a displacement relative to the length direction of the first guide rail 10.

[0060] In the embodiment of the present application, the telescopic mechanism 100 includes a first guide rail 10 and a first guide wheel assembly 20, and the trim cover assembly 200 is connected to the first guide wheel assembly 20. Since the first guide wheel assembly 20 is connected to the first guide rail 10 and can move along the first guide rail 10, the trim cover assembly 200 can follow the first guide wheel assembly 20 to generate a synchronous movement and switch between the extended state and the retracted state; among them, the trim cover assembly 200 can realize the covering function of the outlet of the convertible link 301 in the extended state. In this structure and cooperation form of the first guide wheel assembly 20 and the first guide rail 10, the trim cover assembly 200 can realize the switching between the extended state and the retracted state by telescoping, so the trim cover assembly 200 can have a smaller movement envelope, thereby reducing the risk of interference with the driver and passengers or other structural objects, ensuring the overall safety and reliability of the convertible vehicle.

[0061] Optionally, the telescopic mechanism 100 further includes a driving member 50, the first guide wheel assembly 20 is connected to the output end of the driving member 50, and the driving member 50 is used to drive the first guide wheel assembly 20 to move along the first guide rail 10.

[0062] Among them, the driving member 50 can be a cylinder, a motor or an electric motor. The output end of the driving member 50 is connected to the first guide wheel assembly 20 and is used to drive the first guide wheel assembly 20 to move along the first guide rail 10. Among them, the driving member 50 can drive the first guide wheel assembly 20 to slide along the first guide rail 10, or the driving member 50 can drive the first guide wheel assembly 20 to roll along the first guide rail 10. This application does not make specific limitations on this. Exemplarily, in the embodiment of this application, the driving member 50 is a motor, such as Figure 5 As shown, the output shaft 51 of the motor is connected to the first guide wheel assembly 20 and is used to drive the first guide wheel 21 in the first guide wheel assembly 20 to rotate.

[0063] Such as Figures 2 to 4 As shown, the cover assembly 200 includes a cover body 201 and a second connecting plate 202. The cover body 201 and the second connecting plate 202 are arranged at an angle. The second connecting plate 202 is used to connect to the first guide wheel assembly 20. In the extended state, the cover body 201 covers the outlet of the convertible link 301.

[0064] It should be noted that the cover body 201 can be connected to the first guide wheel assembly 20 through the second connecting plate 202. Among them, the cover body 201 can be designed with a larger area to ensure the shielding effect, and the connecting plate can be designed with a smaller area as a connecting structure, so that the cover assembly 200 is more compact in the overall layout. In practical applications, the second connecting plate 202 can further include a first connecting portion and a second connecting portion. The first connecting portion and the second connecting portion are arranged at an angle. The first connecting portion is connected between the cover body 201 and the second connecting portion. The second connecting portion is used to connect to the first guide wheel assembly 20. Through the angle setting between the first connecting portion and the second connecting portion, and the angle design between the first connecting portion and the cover body 201, different vehicle body structures can be adapted, and the flexibility of the structural design of the cover assembly 200 can be improved.

[0065] Optionally, the first guide wheel assembly 20 includes a first guide wheel 21. The first guide rail 10 is provided with a first guide groove 11. The first guide wheel 21 is movably connected to the first guide groove 11. The design of the first guide groove 11 provides an accurate guiding path for the movement of the first guide wheel 21, thereby ensuring the movement accuracy of the cover assembly 200 and ensuring the covering effect of the cover assembly 200 on the outlet of the convertible link 301 when the first guide wheel assembly 20 moves to the target position.

[0066] Among them, the first guide rail 10 includes a first guide plate. The first guide groove 11 is a through groove provided on the first guide plate. Both sides of the first guide wheel 21 in the radial direction are in contact with the through groove, so that it can be limited by the first guide groove 11 in the up and down two directions, ensuring the stability of its movement path.

[0067] The first guide wheel assembly 20 includes a first guide wheel 21 shaft, which is arranged along the axial direction of the first guide wheel 21 and connected to the first guide wheel 21, and the first guide wheel 21 shaft is at least partially exposed from the first guide groove 11, and the decorative cover assembly 200 is connected to the first guide wheel 21 shaft, and the first guide wheel 21 shaft and the first guide wheel 21 can be fixedly connected or movably connected. Correspondingly, the decorative cover assembly 200 and the first guide wheel 21 shaft are also fixedly connected or movably connected. In actual applications, technicians can design it according to the matching relationship between the first guide wheel 21 and the second guide groove 12.

[0068] In the embodiment of the present application, the first guide wheel 21 is a gear, and the first guide groove 11 is provided with a rack that cooperates with the gear, and the gear and the rack are meshed with each other.

[0069] Specifically, the first guide wheel 21 and the first guide groove 11 are both provided with gear teeth in the circumferential direction, and the gear teeth on the first guide wheel 21 and the first guide groove 11 can mesh with each other. Under this driving structure, since the gear and the rack mesh with each other, when the gear rolls on the rack, it can move strictly according to the preset path and step distance, reducing the gap and offset problems that may exist in the sliding fit mode. In addition, compared with sliding friction, this rolling friction mode can have the advantages of low wear, high running stability, and lower noise, which not only prolongs the service life of the entire device, but also improves the user experience.

[0070] Optionally, the first guide wheel assembly 20 includes a first limiting portion 22 and a second limiting portion 23, the first limiting portion 22 and the second limiting portion 23 are connected to both sides of the first guide wheel 21 along the axial direction, and are respectively clamped on both sides of the first guide groove 11, and the decorative cover assembly 200 is connected to at least one of the first limiting portion 22 and the second limiting portion 23.

[0071] For example, Figure 5 and Figure 6 As shown, the first limiting portion 22 and the second limiting portion 23 are both limiting wheels, and both limiting wheels are sleeved on the shaft of the first guide wheel 21. When the first limiting portion 22 and the second limiting portion 23 are respectively clamped on both sides of the first guide groove 11, since the first guide wheel 21 is movably connected to the first guide groove 11, the first limiting portion 22 and the second limiting portion 23 can limit the axial displacement of the first guide wheel 21, effectively preventing the first guide wheel 21 from separating from the first guide rail 10, ensuring the reliable cooperation between the first guide wheel 21 and the first guide groove 11, and ensuring that the first guide wheel 21 can move along the first guide rail 10 to realize the switching of the decorative cover assembly 200 between the telescopic state and the retracted state. It should be noted that the structural design of the limiting wheel enables the first guide wheel 21 to always be limited by the first limiting portion 22 and the second limiting portion 23 during the movement process, thereby improving the movement reliability of the first guide wheel 21.

[0072] Further, the first guide rail 10 further includes a second guide groove 12. The second guide groove 12 is spaced from the first guide groove 11. The first guide wheel assembly 20 further includes a third limiting portion 24. The third limiting portion 24 is connected to the first guide wheel 21 and is snapped on the side of the second guide groove 12 away from the first guide groove 11. The setting of the third limiting portion 24 further improves the movement accuracy of the first guide wheel 21.

[0073] As Figure 5 shown, the second guide groove 12 is arranged inside the first guide groove 11, and the third limiting portion 24 is arranged inside the second guide groove 12. The third limiting portion 24 cooperates with the first limiting portion 22 and the second limiting portion 23 to form a double limiting structure, providing additional lateral support and constraint for the first guide wheel 21. In addition, the third limiting portion 24 cooperates with the second guide groove 12, indirectly increasing the contact points between the first guide wheel 21 and the first guide rail 10, thereby improving the overall rigidity and stability of the first guide wheel assembly 20, making the movement of the trim cover assembly 200 smoother.

[0074] Optionally, there are two sets of the first guide rail 10 and the first guide wheel assembly 20. The two sets of the first guide rails 10 are arranged at intervals relatively. One set of the first guide wheel assemblies 20 is movably connected to one set of the first guide rails 10.

[0075] As Figure 5 shown, the two sets of the first guide rails 10 are arranged at intervals relatively along the second direction Y. Among them, one set of the first guide rails 10 is movably connected with one set of the first guide wheel assemblies 20, and the trim cover assembly 200 can be connected to the two sets of the first guide wheel assemblies 20 simultaneously. Under the support of this double guide rail, compared with the single guide rail structure, the risk of shaking and offset during the telescopic process of the trim cover assembly 200 is reduced, ensuring the smooth and reliable movement of the trim cover assembly 200. In addition, this redundant design of the double guide rail can ensure the driving effect of the telescopic mechanism 100 on the trim cover assembly 200. Even if one set of the first guide wheel assemblies 20 fails, the trim cover assembly 200 can still be driven to move along the first guide rail 10 through the relative movement between the other set of the first guide wheel assemblies 20 and the first guide rail 10 to realize the switching between the telescopic state and the retracted state, improving the reliability of the entire convertible link covering device.

[0076] Optionally, the first guide rail 10 includes a plurality of first guiding segments, and an angle is formed between adjacent first guiding segments, so that the trim cover assembly 200 can achieve different movement trajectories, improving the flexibility of the movement trajectory design of the trim cover assembly 200.

[0077] As Figure 5As shown, among the multiple first guiding segments, there are straight segments arranged along the first direction X and lifting segments arranged obliquely to the first direction X. The straight segment and the lifting segment are arranged at an angle. During the movement of the first guide wheel assembly 20 on the straight segment, the displacement of the trim cover assembly 200 forward or backward along the first direction X can be realized. During the movement of the first guide wheel assembly 20 on the lifting segment, the displacement of the trim cover assembly 200 rising or falling along the third direction Z can be realized. By setting the lengths and angles of the multiple first guiding segments, the position flexibility of the telescopic mechanism 100 can be improved, so as to realize the telescopic movement of the trim cover assembly 200 while avoiding other vehicle body components. As Figure 4 shown, in the convertible link covering device provided by the embodiment of the present application, during the movement of the first guide wheel assembly 20 along the first guide rail 10, the displacement of the trim cover assembly 200 superposed in the first direction X and the third direction Z can be driven, so that the trim cover assembly 200 moves forward and rises simultaneously during the extension process, and moves backward and descends during the retraction process.

[0078] Optionally, the telescopic mechanism 100 further includes a second guide rail 30 and a second guide wheel assembly 40. The second guide wheel assembly 40 is connected to the second guide rail 30 and can move along the second guide rail 30. The trim cover assembly 200 is also connected to the second guide wheel assembly 40.

[0079] Specifically, as Figures 2 to 5 shown, the second guide rail 30 and the first guide rail 10 are arranged opposite to each other along the second direction Y. The trim cover assembly 200 is connected between the first guide wheel assembly 20 and the second guide wheel assembly 40. It can be understood that since the second guide wheel assembly 40 can move along the second guide rail 30, when the trim cover assembly 200 is simultaneously connected to the first guide wheel assembly 20 and the second guide wheel assembly 40, its movement accuracy can be further improved, the stability of the movement trajectory can be ensured, and the displacement error caused by deviation and shaking can be reduced. Since the trim cover assembly 200 is simultaneously connected to the first guide wheel assembly 20 and the second guide wheel assembly 40, the connection strength between the trim cover assembly 200 and the telescopic mechanism 100 is also enhanced, and the risk of the trim cover assembly 200 being separated from the telescopic mechanism 100 due to external force or service time is reduced.

[0080] Furthermore, there are two sets of the second guide rail 30 and the second guide wheel assembly 40. The two sets of second guide rails 30 are arranged at intervals relative to each other. One set of second guide wheel assemblies 40 is movably connected to one set of second guide rails 30. Specifically, the two sets of second guide rails 30 are arranged along the second direction Y on the outer sides of the two sets of first guide rails 10, so as to guide both sides of the trim cover assembly 200 along the second direction Y, making the movement of the trim cover assembly 200 more stable.

[0081] It should be noted that the second guide wheel assembly 40 has a similar structure to the first guide wheel assembly 20, and the second guide rail 30 has a similar structure to the first guide rail 10, wherein, similar to the structure of the first guide rail 10 and the first guide wheel assembly 20, in the embodiment of the present application, the second guide wheel assembly 40 includes a second guide wheel 41, the second guide rail 30 is provided with a third guide groove 31, and the second guide wheel 41 is movably connected to the third guide groove 31. The design of the third guide groove 31 provides a precise guide path for the movement of the first guide wheel 21, thereby ensuring the movement accuracy of the decorative cover assembly 200 and ensuring the covering effect of the decorative cover assembly 200 on the outlet of the convertible link 301 when the first guide wheel assembly 20 moves to the target position.

[0082] like Figure 7 As shown, the second guide rail 30 includes a second guide plate, and the third guide groove 31 is a through groove arranged on the second guide plate. The second guide wheel 41 is in contact with the through groove on both sides along the radial direction, so that it can accept the limitation of the third guide groove 31 in the upper and lower directions to ensure the stability of its movement path.

[0083] The second guide wheel assembly 40 includes a second guide wheel 41 shaft, which is arranged along the axial direction of the second guide wheel 41 and connected to the second guide wheel 41, and the second guide wheel 41 shaft is at least partially exposed from the third guide groove 31, and the decorative cover assembly 200 is connected to the second guide wheel 41 shaft, and the second guide wheel 41 shaft and the second guide wheel 41 can be fixedly connected or movably connected. Correspondingly, the decorative cover assembly 200 and the second guide wheel 41 shaft are also fixedly connected or movably connected. In actual applications, technicians can design it according to the matching relationship between the second guide wheel 41 and the third guide groove 31.

[0084] Optionally, the second guide wheel assembly 40 includes a fourth limiting portion 42 and a fifth limiting portion 43, the fourth limiting portion 42 and the fifth limiting portion 43 are connected to both sides of the second guide wheel 41 along the axial direction, and are respectively clamped on both sides of the third guide groove 31, and the decorative cover assembly 200 is connected to at least one of the fourth limiting portion 42 and the fifth limiting portion 43.

[0085] For example, Figure 5 and Figure 6 As shown, the fourth limiting portion 42 and the fifth limiting portion 43 are both limiting wheels, and the two limiting wheels are both mounted on the shaft of the second guide wheel 41. When the fourth limiting portion 42 and the fifth limiting portion 43 are respectively clamped on both sides of the second guide groove 12, since the second guide wheel 41 is movably connected to the third guide groove 31, the fourth limiting portion 42 and the fifth limiting portion 43 can limit the axial displacement of the second guide wheel 41, effectively preventing the second guide wheel 41 from disengaging from the second guide rail 30, ensuring the reliable fit between the second guide wheel 41 and the third guide groove 31, and ensuring that the second guide wheel 41 can move along the second guide rail 30, so as to enhance the guiding and limiting effect on the decorative cover assembly 200 during the switching process between the telescopic state and the retracted state.

[0086] Further, the second guide rail 30 further includes a fourth guide groove 32, the fourth guide groove 32 is spaced from the third guide groove 31, the second guide wheel assembly 40 further includes a sixth limiting portion 44, the sixth limiting portion 44 is connected to the second guide wheel 41 and is clamped on a side of the fourth guide groove 32 away from the third guide groove 31. Similar to the function of the third limiting portion 24, the setting of the sixth limiting portion 44 further improves the movement accuracy of the second guide wheel 41.

[0087] As Figure 7 shown, the fourth guide groove 32 is provided outside the third guide groove 31, the sixth limiting portion 44 is provided outside the fourth guide groove 32, and the sixth limiting portion 44 cooperates with the fourth limiting portion 42 and the fifth limiting portion 43 to form a double limiting structure, providing additional lateral support and restraint for the second guide wheel 41. In addition, the sixth limiting portion 44 cooperates with the second guide groove 12, indirectly increasing the contact points between the second guide wheel 41 and the second guide rail 30, thereby improving the overall rigidity and stability of the second guide wheel assembly 40, making the movement of the trim cover assembly 200 smoother.

[0088] Optionally, the second guide rail 30 includes a plurality of second guiding segments, and an angle is provided between adjacent second guiding segments.

[0089] Among them, the angle between the plurality of second guiding segments of the second guide rail 30 is the same as the angle between the plurality of first guiding segments of the first guide rail 10. In this way, when the trim cover assembly 200 moves on the second guide rail 30, its movement trajectory can be synchronized and coordinated with the movement trajectory on the first guide rail 10, thereby ensuring the movement consistency between different components in the telescopic mechanism 100 and reducing the movement interference between components. Specifically, the second guide rail 30 also includes a straight section and a lifting section, so as to play a synchronous guiding role in the movement of the trim cover assembly 200 during the extending process and the retracting process.

[0090] In the embodiment of the present application, the telescopic mechanism 100 further includes a reinforcing plate 60, and the reinforcing plate 60 is connected to the first guide rail 10 to carry the first guide rail 10, the first guide wheel assembly 20, and the trim cover assembly 200.

[0091] Further, the second guide rail 30 is also connected to the reinforcing plate 60. The setting of the reinforcing plate 60 connects the first guide rail 10 and the second guide rail 30 to form an integral body, ensuring the synchronism of the movement trajectories between the first guide wheel assembly 20 and the second guide wheel assembly 40. In this way, it also further ensures the accuracy of the movement path of the trim cover assembly 200. In practical applications, the reinforcing plate 60 can be connected to the trunk lid of the vehicle to ensure the stability of the telescopic mechanism 100.

[0092] In summary, the convertible link covering device provided by the embodiment of the present application can at least include the following advantages:

[0093] In the embodiment of the present application, the telescopic mechanism 100 includes a first guide rail 10 and a first guide wheel assembly 20. The decorative cover assembly 200 is connected to the first guide wheel assembly 20. Since the first guide wheel assembly 20 is connected to the first guide rail 10 and can move along the first guide rail 10, the decorative cover assembly 200 can move synchronously with the first guide wheel assembly 20 and switch between the extended state and the retracted state. Among them, the decorative cover assembly 200 can cover the outlet of the convertible link 301 in the extended state. With this structure and cooperation form between the first guide wheel assembly 20 and the first guide rail 10, the decorative cover assembly 200 can be switched between the extended state and the retracted state by telescoping, so the decorative cover assembly 200 can have a smaller movement envelope, thereby reducing the risk of interference with the driver and passengers or other structural objects, and ensuring the overall safety and reliability of the convertible vehicle.

[0094] The embodiment of the present application also provides a vehicle. As shown in the figure, the vehicle includes a convertible roof 300 and the above-mentioned convertible link covering device. The convertible roof 300 includes a convertible link 301, and the convertible link covering device is connected to the vehicle and is used to cover the outlet of the convertible link 301.

[0095] It should be noted that in the embodiment of the present application, the structure of the convertible link covering device is the same as that of the convertible link covering device in any of the above embodiments, and its beneficial effects are similar, so details are not described here.

[0096] The embodiment of the present application also discloses a control method for a vehicle, which is used to control the above-mentioned vehicle. Among them, the convertible roof 300 includes a convertible storage cover 302 and a convertible body 303; the telescopic mechanism 100 further includes a driving member 50, and the first guide wheel assembly 20 is connected to the output end of the driving member 50, and the driving member 50 is used to drive the first guide wheel assembly 20 to move along the first guide rail 10.

[0097] As Figure 8 shown, it is a control flow chart of the opening and closing process of the convertible link covering device and the convertible roof 300 in the embodiment of the present application. The control method of the vehicle includes:

[0098] After receiving the command to open the convertible roof 300, open the convertible storage cover 302; after receiving the signal that the convertible storage cover 302 is opened in place, start the driving member 50 to control the first guide wheel assembly 20 to move along the first guide rail 10; when the signal that the first guide wheel assembly 20 moves to the target position is not received within the preset time, send a signal that the opening of the convertible body 303 is blocked and turn off the driving member 50; after receiving the signal that the first guide wheel assembly 20 moves to the target position within the preset time, open the convertible body 303; after receiving the signal that the convertible body 303 is opened in place, close the convertible storage cover 302.

[0099] It is understandable that, since the signal that the first guide wheel assembly 20 moves to the target position is not received within the preset time, the vehicle can send a signal that the convertible body 303 is blocked from opening, thereby assisting the driver and passengers in determining whether the convertible body 303 is opened smoothly. After the driver and passengers receive the signal that the convertible body 303 is blocked from opening, they can manually intervene to eliminate the interference between the convertible body 303 and other structures of the vehicle body or external structures, ensuring that the convertible body 303 can be opened smoothly. It should be noted that the closing process of the convertible roof 300 is similar to the opening process, which can be specifically referred to Figure 8 The control flow chart shown will not be repeated here.

[0100] Optionally, two groups of first guide rails 10 and first guide wheel assemblies 20 are provided, the two groups of first guide rails 10 are arranged relatively spaced apart, and one group of first guide wheel assemblies 20 is movably connected to one group of first guide rails 10; after starting the driving member 50, the two groups of first guide wheel assemblies 20 are also controlled by the driving member 50 to move synchronously.

[0101] Specifically, the driving member 50 is a motor, which directly drives the first guide wheel assembly 20 to move, so that the current position of the convertible connecting rod covering device can be determined by directly outputting a signal from the motor, thereby ensuring that the folding and unfolding process of the convertible body 303 does not interfere with the convertible connecting rod covering device, and when the two groups of first guide wheel assemblies 20 move synchronously, the motion interference problem caused by the asynchronous movement of the decorative cover assembly 200 on both sides along the second direction Y can be avoided, thereby ensuring the smoothness of the movement process of the decorative cover assembly 200.

[0102] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0103] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the claims and their equivalents.
