Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a lifting device, a beacon lifting mechanism, a control method, a control device, and a vehicle. Background Technology

[0002] A retractable vehicle emblem, also known as an automatic retractable emblem or smart emblem, is an electromechanical device integrated into the front of the vehicle (usually located on the hood or grille area). Its main feature is that under specific conditions, the emblem can automatically and smoothly rise or retract from inside the vehicle body, transforming the brand logo from a two-dimensional display into a three-dimensional image, enhancing brand recognition and reinforcing the brand's premium image and technological sophistication. Optimizing the implementation of retractable vehicle emblems or other lifting devices to improve the user experience remains a technical challenge requiring ongoing research. Summary of the Invention

[0003] This application provides a lifting device, a sign-raising mechanism, a control method, a control device, and a vehicle, which helps to optimize the implementation of the vehicle's lifting device and improve the user experience.

[0004] In a first aspect, a lifting device is provided, comprising: a lifting platform for carrying decorative parts and / or functional parts; a drive member, drivenly connected to the lifting platform, for driving the lifting platform to move up and down; and a cover plate, drivenly connected to the lifting platform, wherein when the lifting platform moves in a first stroke segment, the cover plate is stationary, and when the lifting platform moves in a second stroke segment, the lifting platform drives the cover plate to move.

[0005] In this embodiment, the decorative components carried by the lifting platform include, but are not limited to, vehicle emblems, and the functional components include, but are not limited to, sensors, lighting components, projection components, and other functional devices. Optionally, in some embodiments, the lifting platform and its lifting device may be located on the side of the vehicle's covering that faces the vehicle interior. The vehicle covering may include, for example, an engine hood, trunk lid, doors, roof panels, side panels, etc. When the lifting platform is in one position, the decorative components and / or functional components it carries may be located in the exterior space of the vehicle; when the lifting platform is in another position, the decorative components and / or functional components it carries may be located in the vehicle's body space. Optionally, in other embodiments, the lifting platform and its lifting device may be located on the side of the vehicle's interior trim that faces the vehicle exterior. When the lifting platform is in one position, the decorative components and / or functional components it carries may be located in the vehicle's passenger compartment; when the lifting platform is in another position, the decorative components and / or functional components it carries may be located in the vehicle's body space.

[0006] When the lifting platform is driven by the drive unit to move in the first stroke segment, the cover plate is stationary. When the lifting platform is driven to move in the second stroke segment, the lifting platform can be used to drive the cover plate to move. This movement may include linear movement, curvilinear movement, flipping movement, or a combination of multiple movement forms, etc.

[0007] Based on the movement of the cover, when the decorative and / or functional components carried by the lifting platform cover the openings of the vehicle's body panels or interior trim and face the vehicle's external space or cabin space, the cover can be stationary in the vehicle's body space; when the decorative and / or functional components carried by the lifting platform are located in the vehicle's body space, the cover can move to cover the openings of the vehicle's body panels or interior trim; the cover and the decorative and / or functional components can alternately cover the openings of the vehicle's body panels or interior trim.

[0008] Through the technical solution of this application embodiment, the lifting device can drive the lifting platform and the cover plate through a single driving component. The driving component drives the lifting platform, which in turn moves the cover plate, resulting in better linkage between the lifting platform and the cover plate. This configuration, on the one hand, helps reduce the structural complexity of the lifting device and the space it occupies, facilitating its placement within the limited space of a vehicle; on the other hand, it improves the continuity and aesthetics of the movement between the decorative parts and / or functional parts and the cover plate, reducing the overall movement time and thus enhancing the user experience. Furthermore, during a portion of the lifting platform's stroke, the cover plate can remain stationary, while during another portion, the lifting platform moves the cover plate. This not only reduces the duration of the cover plate's movement but also reduces the probability of interference between the cover plate and the lifting platform, achieving faster and more reliable movement coordination between them, thereby improving the performance of the lifting device.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, when the lifting platform is in the second stroke segment, the lifting platform is used to drive the cover plate to rotate around the first axis. This rotation movement helps to reduce the travel of the cover plate, thereby facilitating a compact arrangement of the components in the lifting device and improving space utilization. In addition, based on the rotation movement, the cover plate can be longitudinally arranged in the vehicle body space, which helps to reduce the lateral space required by the cover plate and the lifting device.

[0010] Optionally, when the lifting platform is in the second stroke segment, it is also used to move the first axis of the cover plate to rotate. In this way, the rotation of the cover plate is not a one-dimensional fixed-axis rotation, but a multi-dimensional movement and rotation, which makes the movement of the cover plate more flexible, improves the aesthetics of the cover plate movement and enhances the user experience. In addition, the multi-dimensional movement can also more effectively and quickly adapt to the target position of the cover plate to be rotated, further improving the performance of the lifting device.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the second stroke segment is located below the first stroke segment; when the lifting platform descends during the first stroke segment, the cover plate remains stationary at the first position; when the lifting platform descends during the second stroke segment, the cover plate moves from the first position to the second position; when the lifting platform rises during the second stroke segment, the cover plate moves from the second position to the first position; when the lifting platform rises during the first stroke segment, the cover plate remains stationary at the first position. Optionally, the first position is located to the side of the highest position of the lifting platform during the first stroke segment, and the second position is located above the lowest position of the lifting platform during the second stroke segment. This configuration allows for better motion coordination between the lifting platform and the cover plate, making their linkage more effective and resulting in a more compact and smooth movement trajectory.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the lifting stroke of the lifting platform further includes a third stroke segment, which is located below the second stroke segment; when the lifting platform is in the third stroke segment, the cover plate is stationary in the second position.

[0013] Optionally, when the lifting platform is in the third stroke segment, the cover plate can remain stationary; thus, the third stroke segment can be understood as a single stroke position. Alternatively, the lifting platform can move up and down within the third stroke segment; thus, the third stroke segment can include multiple stroke positions. When the third stroke segment includes a single stroke position, the lifting platform can remain stationary during this segment, which helps to lock the cover plate in place and improve its stability. When the third stroke segment includes multiple stroke positions, it improves the flexibility of movement between the lifting platform and the cover plate, thus better adapting to a wider range of application requirements.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the device further includes: a first guide member and a first transmission assembly, the first guide member being fixedly connected to the lifting platform, a first end of the first transmission assembly being slidably connected to the first guide member, and a second end of the first transmission assembly being drively connected to the cover plate; when the lifting platform moves in the first stroke segment, the first guide member slides relative to the first end of the first transmission assembly, and the first end of the first transmission assembly remains stationary; when the lifting platform moves in the second stroke segment, the first guide member is used to drive the first end of the first transmission assembly to move.

[0015] Through the technical solution of this application embodiment, the lifting platform and the cover plate can achieve transmission through a combination of a first guide member and a first transmission assembly. The first guide member rises and falls synchronously with the lifting platform, and the first guide member and the first transmission assembly are slidably connected. By setting the first guide member, the first transmission assembly can remain stationary during the first stroke segment S of the lifting platform, keeping the cover plate stationary. During the second stroke segment of the lifting platform, the first transmission assembly moves, thereby causing the cover plate to flip. The first guide member and the first transmission assembly can reliably and cost-effectively achieve cooperation and linkage between the lifting platform and the cover plate. Furthermore, the guide member can be adjusted according to different application and user needs, allowing for convenient and effective adjustment of the linkage between the lifting platform and the cover plate. The cost of adjusting and replacing the first guide member is low, with minimal impact on the overall structure of the lifting device. This results in better compatibility, enabling the lifting device to be adapted to more scenarios with lower modification costs, meeting the needs of different users.

[0016] Optionally, the first guide member may include a guide groove, and the first end of the first transmission assembly may include a slider matched with the guide groove. Alternatively, in other embodiments, the first guide member may also include a guide rail, a guide shaft, a guide rod, etc., and correspondingly, the first end of the first transmission assembly may include a corresponding matching structure, such as a slider, a bearing, etc. This application does not limit the specific structure of the first guide member and the corresponding first end of the first transmission assembly.

[0017] In conjunction with the first aspect, in some implementations of the first aspect, the first guide member includes a first guide segment and a second guide segment, wherein the first guide segment extends along the lifting direction of the lifting platform, and the second guide segment intersects the first guide segment at an incline; when the lifting platform is in the first stroke segment, the first end of the first transmission component is located in the first guide segment, and when the lifting platform is in the second stroke segment, the first end of the first transmission component is located in the second guide segment.

[0018] The technical solution of this application embodiment provides two guide segments with different directions in the first guide member. These two guide segments enable transmission control of the transmission component, i.e., controlling the transmission component to remain stationary or move. This solution results in a first guide member with low structural complexity and high reliability, making it well-suited for application in the lifting device of this application embodiment. The inclined arrangement of the guide segments in the first guide member allows it to move along with the lifting platform in its lifting direction, and also allows it to simultaneously apply a force to the first end of the transmission component, thereby causing the first end of the transmission component to move and displace. The guide segment arrangement provides better linkage between the lifting platform and the cover plate, improving the aesthetics of the movement.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the first guide member further includes a locking section connected to the second guide section; when the lifting platform is in the third stroke section, the first end of the first transmission component is located in the locking section, and the locking section is used to lock the first end of the first transmission component, thereby further locking the cover plate and improving the stability of the cover plate.

[0020] Optionally, the locking section can be connected to the upper end of the second guide section, and the upper ends of the locking section and the second guide section are arranged along the lifting direction of the lifting platform. This facilitates the lifting platform driving the guide member to move in the lifting direction and stopping at the locking section. The structure of the locking section can be the same as that of the first and second guide sections. For example, if both the first and second guide sections include guide grooves, the locking section can also include a groove structure. The cross-sectional area of ​​the groove structure of the locking section can be small, thereby facilitating better locking of the first end of the first transmission component in multiple directions. The locking section helps improve the stability of the lifting platform, the first transmission component, and the cover plate when the lifting platform is in the third stroke stage, thereby improving the overall structural stability and reliability of the lifting device.

[0021] In conjunction with the first aspect, in some implementations of the first aspect, the first transmission assembly includes a first linkage assembly.

[0022] The design of multiple links in the first linkage assembly allows for various motion trajectories, offering high flexibility and meeting the flipping motion requirements of the cover plate. For example, this first linkage assembly can not only drive the cover plate to flip around the first axis but also move the cover plate along the first axis, achieving multi-dimensional movement of the cover plate and improving its motion flexibility. Furthermore, the first linkage assembly also possesses advantages such as high transmission accuracy, ease of transmitting motion across space, and good force amplification or stroke amplification characteristics, making it well-suited for application in the lifting device of this embodiment.

[0023] In conjunction with the first aspect, in some implementations of the first aspect, the first transmission assembly includes a bent connecting rod. The first end of the bent connecting rod is slidably connected to a first guide member, and the second end of the bent connecting rod is drively connected to a cover plate. The bent portion of the bent connecting rod is rotatably connected to a first fixed fulcrum. When the lifting platform moves in the second stroke segment, the first guide member drives the first end of the bent connecting rod to rotate around the first fixed fulcrum, and the second end of the bent connecting rod drives the cover plate to flip. This bent connecting rod configuration facilitates changing the direction of movement, thereby enabling more flexible coordination between the first guide member and the cover plate to achieve transmission between them.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, the first transmission assembly further includes at least one connecting rod, which is drively connected between the bent connecting rod and the cover plate. The inclusion of this at least one connecting rod facilitates amplifying the travel of the second end of the bent connecting rod and increasing the force exerted on the cover plate, thereby improving the flipping of the cover plate.

[0025] Optionally, at least one link includes two first links, one end of which is rotatably connected to both sides of the cover plate, and the other end of which is rotatably connected to a second fixed fulcrum; the second end of the bent link is driven to either of the two first links to drive the two first links to move, and the two first links are used to drive the cover plate to flip.

[0026] Through the technical solution of this application embodiment, two first connecting rods can be correspondingly arranged on both sides of the cover plate, thereby reliably driving the cover plate to flip and improving the stability of the cover plate flipping. In addition, in this embodiment, the two first connecting rods can be rotatably connected to a fixed fulcrum in the vehicle, so that the two first connecting rods can also have better stability, which is conducive to further improving the stability of the cover plate flipping. Furthermore, a bent connecting rod can be used to realize the synchronous driving of the two first connecting rods, which not only ensures the flipping performance of the cover plate, but also helps to reduce the structural complexity of the lifting device, reduce the cost of the lifting device, and reduce the space occupied.

[0027] Optionally, at least one link further includes a second link, which connects the second end of the bent link to either of the two first links. This second link helps to further improve the transmission performance of the link assembly and optimize the flipping movement path of the cover plate. In some embodiments, one end of the second link may be connected to the second end of the bent link, and the other end of the second link may be connected to the middle region of the first link.

[0028] In conjunction with the first aspect, in some implementations of the first aspect, the cover plate includes a plate-shaped portion and two connecting portions connected to both sides of the plate-shaped portion. One end of each of the two first connecting rods is rotatably connected to a first region of the two connecting portions. A first guide structure is provided in a second region of the two connecting portions. The first guide structure is used to cooperate with a second guide structure connected to a fixed structural member. When the cover plate is flipped, the first guide structure slides relative to the second guide structure.

[0029] In some embodiments, the first guide structure may include a slider, and the second guide structure may include a guide groove. In other embodiments, the first guide structure in the cover plate and the second guide structure in the fixing structure may also be other cooperating guide structures, such as shafts and bearings, etc., which are not specifically limited in this application.

[0030] Optionally, the fixing structure can be a fixing component in a vehicle, or the lifting device can include the fixing structure, which can be located in the housing of the lifting device. In the fixing structure, the guiding direction of the second guide structure (e.g., the extension direction of the guide groove) can be adapted to the flipping movement path of the cover plate, specifically, it can be adapted to the movement path of the first guide structure in the cover plate.

[0031] Through the technical solution of this application embodiment, a matching guide structure can be provided between the cover plate and the fixed connector. On the one hand, the guide structure can provide support for the cover plate, thereby improving the stability of the cover plate flipping. On the other hand, through the design of the guide structure, the flipping and moving path of the cover plate can be made more beautiful and smooth, and can be flexibly adapted to different application scenarios and user needs, so as to further improve the aesthetics of the lifting device and expand its application prospects.

[0032] In conjunction with the first aspect, in some implementations of the first aspect, one end of each of the two first links is rotatably connected to the middle region of the two connecting parts. This allows the first links to effectively move the entire cover plate, rather than just a localized area. A first guide structure is provided at the end region of each of the two connecting parts away from the plate-like portion. By guiding the end region of the connecting part through the first guide structure, the flipping shape of the cover plate can be effectively controlled, allowing the cover plate's shape to reliably adapt to the required application scenario. For example, it can effectively cover a signboard hidden inside a vehicle, improving the overall performance of the lifting device.

[0033] In conjunction with the first aspect, in some implementations of the first aspect, when the lifting platform is in the first stroke segment, at least a portion of the first guide member and the first transmission assembly are located in a first direction of the lifting platform, and the cover plate is located in a second direction of the lifting platform, the first direction intersecting the second direction. Optionally, the second direction may be perpendicular to the first direction.

[0034] This technical solution allows for full utilization of the space surrounding the lifting platform, and allows for the compact arrangement of the first guide component, the first transmission component, and the cover plate, thereby improving the space utilization rate of the lifting device and reducing the space volume required by the lifting device.

[0035] In conjunction with the first aspect, in some implementations of the first aspect, the device further includes: a second transmission assembly, which is tractively connected between the drive member and the lifting platform, and the second transmission assembly includes a second linkage assembly.

[0036] Optionally, the device further includes a second guide member, which extends along the lifting direction of the lifting platform, and the lifting platform is slidably connected to the second guide member.

[0037] Optionally, the second linkage assembly includes a plurality of third linkages connected in series, the drive unit is located on one side of the lifting platform in the lifting direction, and the drive unit is driven to the lifting platform through the plurality of third linkages.

[0038] In this embodiment, the driving component may include a rotary motor whose output shaft can rotate. One end of a plurality of third links connected in series may be hinged to the output shaft of the rotary motor, and the other end may be hinged to the lifting platform. The rotary motor can drive the lifting platform to move by driving the plurality of third links.

[0039] Through the technical solution of this application embodiment, the rotational motion output by the drive component can be converted into linear motion by the cooperation of the second linkage assembly and the second guide member, realizing the reciprocating lifting motion of the lifting platform. The application of the second linkage assembly is beneficial for controlling the smoothness of the lifting platform's movement and the uniformity of speed changes, improving the performance of the lifting device and the aesthetics of the movement of structural components such as the signpost. Furthermore, the second linkage assembly has simple components, is easy to process and maintain, which helps reduce manufacturing and maintenance costs. Moreover, the second linkage assembly is a rigid structure, exhibiting small deformation under load and strong environmental adaptability, which is beneficial for its application in vehicle scenarios.

[0040] In conjunction with the first aspect, in some implementations of the first aspect, the lifting platform includes a base portion and a movable portion, wherein the movable portion is used to carry decorative parts and / or functional parts, and the movable portion is connected to the base portion via a detachable structure, and the base portion is drively connected to a drive component.

[0041] Alternatively, the detachable structure may include a snap-fit ​​structure, a magnetic structure, a detachable adhesive structure, etc.

[0042] When the base and the movable part are connected, the drive unit can drive the base, thereby driving the entire assembly of the base and the movable part, i.e., the lifting platform, to move up and down. When the external force on the decorative parts and / or functional components carried on the movable part exceeds a first force, the detachable structure disengages from the movable part and / or the base, allowing the movable part to detach from the base. For example, the latching structure on the movable part can disengage from the slotting structure on the base, allowing the movable part to descend into the vehicle's interior space under gravity, thus protecting the decorative parts and / or functional components carried on the movable part, providing anti-theft and pedestrian protection functions.

[0043] In this embodiment, the snap-fit ​​structure allows the movable part to detach from the base when subjected to downward or tilted downward external forces. Conversely, when subjected to upward or tilted upward external forces, the snap-fit ​​structure enhances the movable part's resistance to external forces, reducing the risk of theft. Optionally, the upper and lower surfaces of the snap-fit ​​structure can be configured with different structures and / or shapes to adapt to different responses of the movable part to upward and downward forces.

[0044] In conjunction with the first aspect, in some implementations of the first aspect, the lifting platform is equipped with a force sensor for detecting external forces acting on the decorative parts and / or functional parts. Optionally, the force sensor and the drive unit are electrically connected to a control device in the vehicle, and the control device controls the drive unit based on the detection signal from the force sensor. As an example, if the force indicated by the detection signal from the force sensor is greater than a first value, the control device can control the drive unit to lower the lifting platform. This first value can be flexibly set according to requirements, and this application embodiment does not specifically limit it. In this way, the lifting device can achieve automatic lowering of the lifting platform through the cooperation of the force sensor, the control device, and the drive unit, thereby protecting the decorative parts and / or functional parts carried on the lifting platform, providing anti-theft and pedestrian protection functions.

[0045] In conjunction with the first aspect, in some implementations of the first aspect, the decorative element includes the vehicle's emblem.

[0046] In a second aspect, a sign-erecting lifting mechanism is provided, comprising: a sign, and a lifting device provided in the first aspect or any implementation thereof, wherein a lifting platform in the lifting device is used to support the sign.

[0047] Thirdly, a control method is provided, comprising: acquiring a first message; controlling the movement of a lifting platform in a lifting device according to the first message, wherein the lifting platform is used to carry decorative parts and / or functional parts, and when the lifting platform moves in a first stroke segment, the cover plate in the lifting device is stationary, and when the lifting platform moves in a second stroke segment, the lifting platform is used to drive the cover plate to move.

[0048] Fourthly, a control device is provided, comprising: a memory for storing a computer program; and a processor for executing the computer program stored in the memory, such that the device performs the method provided in the third aspect.

[0049] Fifthly, a vehicle is provided, comprising: a lifting device provided in the first aspect or any implementation thereof, or a beacon lifting mechanism provided in the second aspect.

[0050] Optionally, the vehicle also includes a control device connected to a drive component in the lifting device or the beacon lifting mechanism. The control device controls the drive component to drive the lifting platform in the beacon lifting mechanism to move up and down. Optionally, the control device is also connected to a force sensor on the lifting platform and controls the drive component based on the detection signal from the force sensor.

[0051] In some embodiments, the control device may include the control device provided in the fourth aspect. Attached Figure Description

[0065] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0066] This application relates to intelligent driving devices, which may include road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment. For example, an intelligent driving device can be a vehicle, which is a broad concept and can include transportation vehicles (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.), amusement equipment, toy vehicles, etc. This application does not specifically limit the type of vehicle. For example, vehicles in this application may include pure electric vehicles (pure EV / battery EV), hybrid electric vehicles (HEV), range-extended electric vehicles (REEV), plug-in hybrid electric vehicles (PHEV), or new energy vehicles (NEV), etc.

[0067] More specifically, embodiments of this application relate to a lifting device in intelligent driving equipment. In some embodiments, the lifting device can be used to carry a three-dimensional vehicle emblem (also referred to as a hood ornament), forming a hood ornament lifting mechanism for the vehicle. Alternatively, in other embodiments, the lifting device can be used to carry other functional structural components of the vehicle, such as sensors, lighting components, and projection components. These functional structural components can rise from inside the vehicle body under specific conditions to detect the external environment or expand the interaction dimensions between the vehicle and the user, thereby improving the user experience. Or, in yet another example, the lifting device can be used to carry both the vehicle hood ornament and other functional structural components such as sensors, lighting components, and projection components, thereby improving the integration of the vehicle hood ornament lifting mechanism with the vehicle's intelligent network system, sensor system, and other systems.

[0068] As an example, Figure 1 A schematic diagram of a vehicle according to an embodiment of this application is shown. The engine compartment below the hood of this vehicle may be equipped with a sign-lifting mechanism 100. For example... Figure 1 As shown in part (a) of the document, in certain vehicle states, such as when the vehicle is unlocked or ignited, the emblem lifting mechanism 100 can control the emblem 101 of the vehicle to rise from the engine compartment to the external space of the engine hood. Figure 1 As shown in section (b), in other vehicle states, such as when the vehicle is locked or the engine is off, the emblem lifting mechanism 100 can control the emblem 101 to descend and retract into the engine compartment below the hood. Furthermore, to seal the opening formed on the hood surface after the emblem 101 descends, the emblem lifting mechanism 100 or other lifting mechanisms in the vehicle can control the cover 102 to rise from the engine compartment below the hood, sealing the opening formed on the hood surface. By way of example and not limitation, the cover 102 may include, for example, a flat emblem.

[0069] Figure 1 As an example, a schematic diagram of the position of a beacon lifting mechanism 100 in a vehicle provided in an embodiment of this application is shown. Optionally, the beacon lifting mechanism 100 can also be set in other positions in the vehicle as needed, such as the air intake grille or the front bumper area, etc.; the embodiment of this application does not specifically limit the position of the beacon lifting mechanism in the vehicle.

[0070] In some traditional sign-lifting mechanisms, the linkage between the cover plate and the sign is poor. They are connected to different drive and transmission components, resulting in a complex mechanical structure and a large space requirement. In addition, the separate control of the cover plate and the sign can easily cause interference between them during movement. Alternatively, to reduce the probability of interference, the movement of the sign and the cover plate may be interrupted, affecting the overall movement duration and aesthetics, thus impacting the user experience.

[0071] In view of this, the present application provides a lifting device that can be better applied to the sign lifting mechanism to realize the linkage between the sign and the cover plate. The lifting device has a compact overall structure and is conducive to improving the continuity and aesthetics of the movement of the sign and the cover plate, reducing the overall movement time of the sign and the cover plate, thereby improving the user experience.

[0072] As an example, Figure 2 A schematic diagram of a lifting device provided in an embodiment of this application is shown.

[0073] like Figure 2 As shown, the lifting device 200 includes a lifting platform 210, a cover plate 220, and a drive component 230. The lifting platform 210 is used to carry decorative components and / or functional components. The decorative components include, but are not limited to, the vehicle's emblem 101, and the functional components include, but are not limited to, sensors, lighting components, projection components, and other functional devices. Optionally, in some embodiments, the lifting platform 210 and the lifting device 200 thereon may be located on the side of the vehicle's covering that faces the vehicle interior. The vehicle's covering may include, for example, an engine hood, trunk lid, doors, roof panels, side panels, etc. When the lifting platform 210 is in one position, the decorative components and / or functional components it carries may be located in the vehicle's exterior space; when the lifting platform 210 is in another position, the decorative components and / or functional components it carries may be located in the vehicle's interior space. Optionally, in other embodiments, the lifting platform 210 and the lifting device 200 thereon may be located on the side of the vehicle's interior trim opening facing the outside of the vehicle. When the lifting platform 210 is in one position, the decorative parts and / or functional parts it carries may be located in the vehicle's cabin space; when the lifting platform 210 is in another position, the decorative parts and / or functional parts it carries may be located in the vehicle's body space.

[0074] The drive unit 230 is connected to the lifting platform 210 for driving the lifting platform 210 to move up and down. The cover plate 220 is connected to the lifting platform 210, wherein, as... Figure 2 As shown in part (a), when the lifting platform 210 moves in the stroke segment S1, the cover plate 220 can remain stationary; as Figure 2As shown in section (b), when the lifting platform 210 is moving in stroke segment S2, the lifting platform 210 can be used to drive the cover plate 220 to move. As an example, Figure 2 The travel segment S1 of the lifting platform 210 may include a travel segment between position P1 and position P2. When the lifting platform 210 moves between position P1 and position P2, the cover plate 220 can be stationary at position P'1 as shown in the figure. The travel segment S2 of the lifting platform 210 may include a travel segment between position P2 and position P3. When the lifting platform 210 moves between position P2 and position P3, the lifting platform 210 is used to drive the cover plate 220 to move. This movement may include, for example, linear movement, curvilinear movement, flipping movement, or a composite movement including multiple forms of movement, etc. As an example, such as... Figure 2 As shown in part (b), when the lifting platform 210 changes from position P2 to position P3, the cover plate 220 can change from position P'1 to position P'2.

[0075] Based on the movement of the cover 220, when the decorative and / or functional components carried by the lifting platform 210 are located in the vehicle's body space, the cover 220 can cover the openings of the vehicle's body panels or interior trim. When the decorative and / or functional components carried by the lifting platform 210 cover the openings of the vehicle's body panels or interior trim and face towards the vehicle's exterior space or cabin space, the cover 220 can be located in the vehicle's body space. The cover 220 and the decorative and / or functional components can alternately cover the openings of the vehicle's body panels or interior trim.

[0076] Through the technical solution of this application embodiment, the lifting device can drive the lifting platform and the cover plate through a single driving component. The driving component drives the lifting platform, which in turn moves the cover plate, resulting in better linkage between the lifting platform and the cover plate. This configuration, on the one hand, helps reduce the structural complexity of the lifting device and the space it occupies, facilitating its placement within the limited space of a vehicle; on the other hand, it improves the continuity and aesthetics of the movement between the decorative parts and / or functional parts and the cover plate, reducing the overall movement time and thus enhancing the user experience. Furthermore, during a portion of the lifting platform's stroke, the cover plate can remain stationary, while during another portion, the lifting platform moves the cover plate. This not only reduces the duration of the cover plate's movement but also reduces the probability of interference between the cover plate and the lifting platform, achieving faster and more reliable movement coordination between them, thereby improving the performance of the lifting device.

[0077] In some embodiments of this application, the positions P1, P2, and P3 of the lifting platform 210 can be arranged along the descending direction of the lifting platform 210, that is, the travel segment S2 is located below the travel segment S1. The movement of the lifting platform 210 from position P1 to position P3 can be understood as the lifting platform being in a descending state, and the movement of the lifting platform 210 from position P3 to position P1 can be understood as the lifting platform being in an ascending state. Alternatively, in other embodiments, the positions P1, P2, and P3 of the lifting platform 210 can be arranged along the ascending direction of the lifting platform 210, that is, the travel segment S2 is located above the travel segment S1.

[0078] Optionally, when the lifting platform 210 is used to support the emblem, the lifting direction of the lifting platform 210 can be parallel to or intersect the height direction of the vehicle at a small angle. When the lifting platform 210 descends, the emblem carried by the lifting platform 210 can rise from the engine compartment to the outside of the vehicle, and when the lifting platform 210 rises, the emblem carried by the lifting platform 210 can descend from the outside of the vehicle to the engine compartment. In other embodiments, the lifting direction of the lifting platform 210 may not be the height direction of the vehicle, but may be the length direction, width direction, or other directions of the vehicle; this application does not specifically limit this. Optionally, the rising direction of the lifting platform 210 can be the direction of movement from the vehicle body space to the external space / cabin space, and the descending direction of the lifting platform 210 can be the direction of movement from the external space / cabin space of the vehicle to the vehicle body space.

[0079] like Figure 2 As shown, taking the stroke segment S2 being below the stroke segment S1 as an example, when the lifting platform 210 descends during stroke segment S1, the cover plate 220 can remain stationary at position P'1. When the lifting platform 210 descends during stroke segment S2, the cover plate 220 can move from position P'1 to position P'2. When the lifting platform 210 ascends during stroke segment S2, the cover plate 220 can move from position P'2 to position P'1. When the lifting platform 210 ascends during stroke segment S1, the cover plate 220 can remain stationary at position P'1. In this way, the lifting platform 210 and the cover plate 220 can achieve better motion coordination, and the linkage between the two is more effective, which helps to make their motion trajectories more compact and smooth.

[0080] Optionally, when the lifting platform 210 is in position P2, the decorative parts and / or functional parts carried on the lifting platform 210 can be located in the vehicle's body space, that is, the decorative parts and / or functional parts are not visible in the vehicle's exterior space or cabin space. This arrangement allows the decorative parts and / or functional parts to be reliably hidden in the vehicle's body space via the travel segment S1, reducing the risk of the decorative parts and / or functional parts being exposed.

[0081] Optionally, the lifting platform 210 may further include a travel segment S3, which may be located below the travel segment S2. When the lifting platform 210 is in the travel segment S3, the cover plate 220 may remain stationary, for example, stationary at position P'2. Optionally, the lifting platform 210 may remain stationary in the travel segment S3, which can be understood as a single travel position. Alternatively, the lifting platform 210 may move up and down in the travel segment S3, which may include multiple travel positions. In some embodiments, Figure 2 Position P1, as shown, can be the highest position of the lifting platform 210, and position P3 or a position below P3 can be the lowest position of the lifting platform 210. When the stroke segment S3 includes a single stroke position, the lifting platform 210 can remain stationary during stroke segment S3, which facilitates locking the cover plate 220 and improves the stability of the cover plate 220. When the stroke segment S3 includes multiple stroke positions, it improves the flexibility of movement between the lifting platform 210 and the cover plate 220, thus adapting to more application requirements.

[0082] In some embodiments of this application, when the lifting platform 210 is moving in the stroke segment S2, the lifting platform 210 can be used to drive the cover plate 220 to rotate around a first axis. This first axis is... Figure 2 The diagram shows axis A1, which can be a straight line perpendicular to the plane of the paper. Figure 2 Solid black dots and shaded black dots indicate the positions of axis A1 when the cover plate 220 is in position P'1 and position P'2, respectively. Optionally, position P'1 can be located to the side of the lifting platform 210 at the highest position of stroke segment S1 (i.e., position P1), and position P'2 can be located above the lifting platform 210 at the lowest position of stroke segment S2 (i.e., position P3). The flipping motion can better realize the transformation of the cover plate 220 between position P'1 and position P'2, and the cover plate 220 can be longitudinally arranged in the vehicle body space, which helps to reduce the lateral space required by the cover plate 220 and the lifting device 200. Optionally, when the cover plate 220 is in position P'1, the large surface of the cover plate 220 can be parallel to the lifting direction of the lifting platform 210, and when the cover plate 220 is in position P'2, the large surface of the cover plate 220 can be perpendicular to or intersect with the lifting direction of the lifting platform 210. In other embodiments, the orientation of the large surface of the cover plate 220 at different locations can be set to other orientations depending on factors such as vehicle space and vehicle body shape. This application does not specifically limit this aspect.

[0083] Optionally, such as Figure 2As shown, when the lifting platform 210 moves in the stroke segment S2, the lifting platform 210 is also used to drive the axis A1 of the cover plate 220 to move. Thus, the flipping motion of the cover plate 220 is not a one-dimensional fixed-axis flipping motion, but a multi-dimensional movement and flipping motion, which makes the movement of the cover plate 220 more flexible, improves the aesthetics of the movement of the cover plate 220 and enhances the user experience. In addition, the multi-dimensional movement can also more effectively and quickly adapt to the target position required for the flipping of the cover plate 220, further improving the performance of the lifting device 200.

[0084] In some embodiments of this application, a transmission assembly is provided between the lifting platform 210 and the driving member 230, and the driving member 230 can drive the transmission assembly to move, thereby causing the lifting platform 210 to move up and down. As an example, Figure 3 A schematic diagram of another lifting device provided in an embodiment of this application is shown. Figure 3 The lifting device in the diagram omits the cover plate 220, which is intended to illustrate the transmission method between the lifting platform 210 and the drive unit 230.

[0085] like Figure 3 As shown, in the lifting device 200, the drive member 230 can be located on one side of the lifting platform 210 in the lifting direction. A transmission assembly 240 is provided between the lifting platform 210 and the drive member 230. The transmission assembly 240 may include multiple series-hinged links. Among the multiple series-hinged links, one end of any one link can be hinged to one end of another link, the drive member 230, or the lifting platform 210. As an example, Figure 3 The diagram illustrates connecting rods 240-a and 240-b connected in series. One end of connecting rod 240-a can be hinged to the lifting platform 210, and the other end can be hinged to one end of connecting rod 240-b. The other end of connecting rod 240-b can be hinged to the drive member 230. In this embodiment, the drive member 230 may include a rotary motor whose output shaft is rotatable. One end of the multiple connecting rods connected in series can be hinged to the output shaft of the rotary motor, and the other end can be hinged to the lifting platform. The rotary motor can drive the lifting platform to move by driving the multiple connecting rods.

[0086] Furthermore, in order to achieve smooth movement of the lifting platform 210 in a single direction, such as Figure 3 As shown, the lifting device 200 may further include a guide member 250, which extends along the lifting direction of the lifting platform 210, and the lifting platform 210 is slidably connected to the guide member 250. By way of example and not limitation, the guide member 250 may include, but is not limited to, a guide groove, a guide rail, a guide column, an optical axis, etc. The lifting platform 210 may cooperate with the guide member 250 through structures such as sliders, guide sleeves, bearings, etc., so that the lifting platform 210 can be slidably connected on the guide member 250.

[0087] Through the technical solution of this application embodiment, the rotational motion output by the drive component can be converted into linear motion by the cooperation of the linkage assembly and the guide component, realizing the reciprocating lifting motion of the lifting platform. The application of the linkage assembly is beneficial for controlling the smoothness of the lifting platform's movement and the uniformity of speed changes, improving the performance of the lifting device and the aesthetics of the movement of structural components such as the signpost. Furthermore, the linkage assembly has simple components, is easy to process and maintain, which helps reduce manufacturing and maintenance costs. Moreover, the linkage assembly is a rigid structure, exhibiting small deformation under load and strong environmental adaptability, which is beneficial for its application in vehicle scenarios.

[0088] Figure 3 This illustration only demonstrates a transmission connection method between the lifting platform 210 and the driving member 230 according to an embodiment of this application; in other embodiments, other transmission connection methods may be used between the lifting platform 210 and the driving member 230. Optionally, the transmission connection between the lifting platform 210 and the driving member 230 may be omitted. Figure 3 The guide shown is used to achieve linear motion of the lifting platform 210 through other forms of linkage mechanisms, such as Watt's linear linkage mechanism, etc. Optionally, in addition to using linkage assemblies to achieve transmission between the lifting platform 210 and the drive unit 230, other components can also be used to achieve transmission, such as lead screw drive, gear / rack drive, synchronous belt drive, etc.

[0089] The above text combined Figure 3 This section explains the transmission method between the drive unit 230 and the lifting platform 210 in the embodiments of this application. The following section, in conjunction with... Figures 4 to 10 This describes the transmission method between the lifting platform 210 and the cover plate 220 in the embodiments of this application.

[0090] Figure 4 A schematic diagram of yet another lifting device provided in an embodiment of this application is shown.

[0091] like Figure 4 As shown, in addition to the lifting platform 210, cover plate 220, and drive component 230, the lifting device 200 may also include a transmission assembly 270 and a guide component 260. The guide component 260 is fixedly connected to the lifting platform 210, the first end of the transmission assembly 270 is slidably connected to the guide component 260, and the second end of the transmission assembly 270 is drively connected to the cover plate 220. When the lifting platform 210 moves in the stroke segment S1, the guide component 260 slides relative to the first end of the transmission assembly 270, and the first end of the transmission assembly 270 remains stationary. When the lifting platform 210 moves in the stroke segment S2, the guide component 260 drives the first end of the transmission assembly 270 to move, thereby enabling the transmission assembly 270 to drive the cover plate 220 to move.

[0092] Through the technical solution of this application embodiment, the lifting platform 210 and the cover plate 220 can achieve transmission through a combination of guide member 260 and transmission assembly 270. The guide member 260 rises and falls synchronously with the lifting platform 210, and the guide member 260 and transmission assembly 270 are slidably connected. By setting the guide member 260, the transmission assembly 270 can remain stationary during the stroke segment S1 of the lifting platform 210, thus keeping the cover plate 220 stationary. During the stroke segment S2 of the lifting platform 210, the transmission assembly 270 moves, thereby causing the cover plate 220 to flip. The guide component 260 and the transmission assembly 270 can reliably and cost-effectively achieve the cooperation and linkage between the lifting platform 210 and the cover plate 220. In addition, the guide component 260 can be adjusted according to different application requirements and user needs, which can conveniently and effectively adjust the linkage relationship between the lifting platform 210 and the cover plate 220. The cost of adjusting and replacing the guide component 260 is low, and it has little impact on the overall structure of the lifting device 200. As a result, the lifting device 200 has better compatibility and can be adapted to more scenarios with lower modification costs to meet the needs of different users.

[0093] In some embodiments, such as Figure 4 As shown, the guide member 260 may include a guide groove, and the first end of the transmission assembly 270 may include a slider that matches the guide groove. Alternatively, in some other embodiments, the guide member 260 may also include a guide rail, a guide shaft, a guide rod, etc., and correspondingly, the first end of the transmission assembly 270 may include a corresponding matching structure, such as a slider, a bearing, etc. This application does not limit the specific structure of the guide member 260 and the corresponding first end of the transmission assembly 270.

[0094] In some embodiments, such as Figure 4 As shown, the transmission assembly 270 may include a linkage assembly. Through the design of multiple links in the linkage assembly, various forms of motion trajectories can be achieved, offering high flexibility and meeting the flipping motion requirements of the cover plate 220. For example, this linkage assembly can not only drive the cover plate 220 to flip around the first axis, but also drive the cover plate 220 to move along the first axis, realizing multi-dimensional movement of the cover plate 220 and improving its motion flexibility. In addition, the linkage assembly also has advantages such as high transmission accuracy, ease of transmitting motion across space, and good force amplification or stroke amplification characteristics, making it optimally applicable to the lifting device 200 in this embodiment. Optionally, in Figure 4The transmission assembly 270 shown may include connecting rods 271, 272, and 273. The first end of the transmission assembly 270 connected to the guide member 260 may be the connecting rod 271 connected to one end of the guide member 260. In addition, the second end of the transmission assembly 270 connected to the cover plate 220 may be the connecting rod 273 connected to one end of the cover plate 220.

[0095] Figure 5 A schematic diagram of a guide component provided in an embodiment of this application is shown. Figure 5 It can be Figure 4 The illustrated embodiment shows a schematic diagram of the guide member 260 in the xz plane. In various embodiments of this application, the x-direction can be the lifting direction of the lifting platform 210, and the y-direction and z-direction can be perpendicular to the x-direction, and they are also perpendicular to each other.

[0096] like Figure 5 As shown, the guide member 260 may include a guide segment 261 and a guide segment 262, wherein the guide segment 261 extends along the x-direction, i.e., along the lifting direction of the lifting platform 210, and the guide segment 262 may obliquely intersect the guide segment 261. Optionally, the guide segment 262 may include a straight segment and / or a curved segment. Optionally, the guide segment 262 may have a guiding function in directions other than the x-direction (e.g., the z-direction or y-direction), which may be matched according to the configuration of the transmission assembly 270. For example, in combination with Figure 4 and Figure 5 In the embodiment shown, the guide segment 262, which is matched with the transmission assembly 270, has a guiding function in the x-direction and also a guiding function in the z-direction.

[0097] When the lifting platform 210 moves in the stroke segment S1, the first end of the transmission assembly 270 can be stationary in the guide segment 261, and the guide segment 261 slides in the x direction relative to the first end of the transmission assembly 270. When the lifting platform 210 moves in the stroke segment S2, the first end of the transmission assembly 270 can be located in the guide segment 262 and slide in the guide segment 262.

[0098] The technical solution of this application embodiment provides two guide segments with different directions in the guide member 260. These two guide segments enable transmission control of the transmission component 270, allowing the transmission component 270 to be controlled to remain stationary or move. This solution results in a guide member 260 with low structural complexity and high reliability, making it well-suited for use in the lifting device of this application embodiment. The inclined arrangement of the guide segment 262 in the guide member 260 allows the guide member 260 to move in the x-direction along with the lifting platform 210, and also allows the guide member 260 to simultaneously apply a force to the first end of the transmission component 270, thereby causing the first end of the transmission component 270 to move and displace. The arrangement of the guide segment 262 provides better linkage between the lifting platform 210 and the cover plate 220, improving the aesthetics of the movement.

[0099] In this embodiment, guide segment 262 can be connected to the upper end of guide segment 261, and the included angle between guide segment 262 and guide segment 261 is an obtuse angle, thereby enabling guide segment 261 and guide segment 262 to match the linkage between lifting platform 210 and cover plate 220. By setting this included angle, the flipping speed of cover plate 220 can be flexibly adjusted, thereby optimizing the aesthetics of cover plate 220's movement.

[0100] In some embodiments, such as Figure 5 As shown, the guide member 260 may also include a locking section 263 connected to the guide section 262; when the lifting platform 210 is in the stroke segment S3, the first end of the transmission assembly 270 may be located in the locking section 263, and the locking section 263 may be used to lock the first end of the transmission assembly 270, thereby further locking the cover plate 220 and improving the stability of the cover plate 220.

[0101] Optionally, the locking segment 263 can be connected to the upper end of the guide segment 262, and the locking segment 263 and the upper end of the guide segment 262 are arranged along the x-direction. This facilitates the movement of the guide member 260 by the lifting platform 210 in the x-direction, stopping at the locking segment 263. The structure of the locking segment 263 can be the same as that of the guide segments 261 and 262. For example, if both the guide segments 261 and 262 include guide grooves, the locking segment 263 can also include a groove structure. The cross-sectional area of ​​the groove structure of the locking segment 263 can be small, thereby facilitating better locking of the first end of the transmission component 270 in multiple directions. The installation of the locking segment 263 helps improve the stability of the lifting platform 210, the transmission component 270, and the cover plate 220 when the lifting platform 210 is in the stroke segment S3, thereby improving the overall structural stability and reliability of the lifting device 200.

[0102] Optionally, in some embodiments, in order to reduce structural complexity, the locking section 263 may be omitted from the guide member 260, and the lifting platform 210 may be locked by the driving member 230, thereby locking other structures in the lifting device 200 (such as the transmission assembly 270 and the cover plate 220).

[0103] exist Figure 5 In the illustrated embodiment, the guide member 260 may include guide segments 261, 262, and locking segments 263, and may also include a connecting structure, through which the guide member 260 can be connected to the lifting platform 210. This is an example and not a limitation. Figure 5 The diagram shows a plurality of hole structures in the guide member 260, which can be connected to the lifting platform 210 by screws / bolts, etc. Alternatively, in other examples, the guide member 260 can also be fixedly connected to the lifting platform 210 by other detachable or non-detachable means. Or, in yet another embodiment, the guide member 260 can be integrally formed with at least a portion of the structure of the lifting platform 210. This application does not specifically limit the connection method between the guide member 260 and the lifting platform 210.

[0104] Optionally, in some embodiments, the guide member 260 may have a connecting structure at the upper end of the guide segment 262 to connect to the lifting platform 210. Further, return Figure 4 As shown, the guide member 260 can be connected to the lower end of the lifting platform 210. Alternatively, in some other embodiments, the relative position between the guide member 260 and the lifting platform 210 can be set in other ways to adapt to the linkage requirements between the lifting platform 210 and the cover plate 220.

[0105] Continue to return to see Figure 4 As shown, in the transmission assembly 270, the connecting rod 271 connected to the guide member 260 may include a bent connecting rod, or a non-linear connecting rod. The first end of this bent connecting rod is slidably connected to the guide member 260, and the second end is driveably connected to the cover plate 220. The bent portion of the bent connecting rod is rotatably connected to a fixed fulcrum in the vehicle. This bent connecting rod facilitates changing the direction of movement, allowing for more flexible coordination between the guide member 260 and the cover plate 220, thus realizing the transmission between them.

[0106] As an example, Figures 6 to 8 Schematic diagrams of several other lifting devices provided in embodiments of this application are shown.

[0107] like Figure 6As shown, when the drive member 230 drives multiple links in the transmission assembly 240 to drive the lifting platform 210 to the stroke segment S1, the first end 2711 of the bent link is located in the guide segment 261 of the guide member 260 and remains stationary. Thus, other links in the transmission assembly 270, such as links 272 and 273 shown in the figure, also remain stationary, and the transmission assembly 270 does not move the cover plate 220; the cover plate 220 remains in the same position.

[0108] like Figure 7 As shown, when the drive member 230 drives multiple links in the transmission assembly 240 to drive the lifting platform 210 to the stroke segment S2, the first end 2711 of the bending link is located in the guide segment 262 of the guide member 260. The guide member 260 is used to drive the first end 2711 of the bending link to rotate around a fixed fulcrum. The fixed fulcrum is rotatably connected to the bending portion 2713 of the bending link. The second end 2712 of the bending link is used to drive the cover plate 220 to flip.

[0109] As an example, Figure 7 The dashed arrows indicate the descent direction D of the lifting platform 210, and also show the rotational motion directions R1 and R2 of the first end 2711 and the second end 2712 of the bending link when the lifting platform 210 moves along the descent direction D and is in the stroke segment S2. Similarly, when the lifting platform 210 moves along the ascending direction, the rotational motion directions of the first end 2711 and the second end 2712 of the bending link can be opposite to those shown in the figure.

[0110] In this embodiment, both the bending link and the guide 260 can be disposed in the xz plane, and the extension direction of the guide segment in the guide 260 can be parallel to the xz plane. Optionally, in the guide 260, the guide segment 262 can include a straight segment; for example, the two ends of the guide segment 262 can be located at the two ends of the arc segment in the rotation trajectory of the first end 2711 of the bending link. Optionally, the guide segment 262 can include a curved segment; for example, the guide segment 262 can coincide with the arc segment in the rotation trajectory of the first end 2711 of the bending link.

[0111] like Figure 8 As shown, when the drive member 230 drives multiple links in the transmission assembly 240 to drive the lifting platform 210 to its lowest position, the first end 2711 of the bent link is located in the locking section 263 of the guide member 260. The locking section 263 is used to lock the first end 2711 of the bent link, so that the bent link remains stationary. In this way, other links in the transmission assembly 270, such as links 272 and 273 shown in the figure, also remain stationary, so that the cover plate 220 can be locked and held in the same position.

[0112] Combination Figures 4 to 8 As shown in some embodiments of this application, the transmission assembly 270 connecting the guide member 260 and the cover plate 220 may include, in addition to the bending connecting rod, one or more connecting rods, which are transmissionally connected between the bending connecting rod and the cover plate 220. The arrangement of these one or more connecting rods is beneficial to amplifying the travel of the second end of the bending connecting rod and increasing the force exerted on the cover plate 220, thereby facilitating a better realization of the flipping of the cover plate 220.

[0113] Figure 9 A schematic diagram of yet another lifting device provided in an embodiment of this application is shown. For ease of illustration and explanation, in this… Figure 9 In the illustrated embodiment, the cover plate 220 in the lifting device 200 and the decorative and / or functional components carried on the lifting platform 210 are not shown.

[0114] like Figure 9 As shown, in the lifting device 200, the transmission assembly 270, which is connected between the cover plate 220 and the guide member 260, may include connecting rods 273-a and 273-b. The first ends of connecting rods 273-a and 273-b are rotatably connected to the two sides of the cover plate 220, respectively, and the second ends of connecting rods 273-a and 273-b are rotatably connected to a fixed fulcrum in the vehicle. The line connecting the first ends of connecting rods 273-a and 273-b forms a first axis of the cover plate 220, around which the cover plate 220 can rotate.

[0115] In some embodiments, link 273-a and link 273-b can be connected to each other, for example, by means of... Figure 9 The connecting parts 282 shown are interconnected. The second end 2712 of the bent connecting rod can be driven to either connecting rod 273-a or connecting rod 273-b to drive the connecting rod 273-a and connecting rod 273-b to move synchronously. Furthermore, connecting rod 273-a and connecting rod 273-b can be used to drive the cover plate 220 to flip.

[0116] In other embodiments, connecting rods 273-a and 273-b may not be connected to each other. The lifting device 200 may include two sets of guides 260 and bent connecting rods, wherein the second end 2712 of one bent connecting rod may be driven to the connecting rod 273-a, and the second end 2712 of the other bent connecting rod may be driven to the connecting rod 273-b.

[0117] Optionally, such as Figure 9As shown, the second ends of connecting rod 273-a and connecting rod 273-b are rotatably connected to the two ends of connector 281, which can be fixedly mounted in the vehicle as a fixed fulcrum. The second ends of connecting rod 273-a and connecting rod 273-b can rotate around the two ends of connector 281. Alternatively, in some other embodiments, the second ends of connecting rod 273-a and connecting rod 273-b can also be rotatably connected to a fixed fulcrum in the vehicle in other ways. This application does not specifically limit this aspect.

[0118] Through the technical solution of this application embodiment, connecting rods 273-a and 273-b are correspondingly arranged on both sides of the cover plate 220, thereby reliably driving the cover plate 220 to flip and improving the stability of the cover plate 220 flipping. Furthermore, in this embodiment, the second ends of connecting rods 273-a and 273-b can be rotatably connected to a fixed fulcrum in the vehicle, allowing connecting rods 273-a and 273-b to also have good stability, further improving the stability of the cover plate 220 flipping. Moreover, a bent connecting rod can be used to synchronously drive connecting rods 273-a and 273-b, ensuring the flipping performance of the cover plate 220 while also reducing the structural complexity of the lifting device 200, lowering its cost, and reducing the space required.

[0119] Referring again to Figure 9, optionally, a connecting rod 272 is also connected between connecting rod 273-a and the second end 2712 of the bent connecting rod. The arrangement of this connecting rod 272 helps to further improve the transmission performance of the connecting rod assembly and optimize the flipping movement path of the cover plate 220. In some embodiments, one end of the connecting rod 272 can be connected to the second end 2712 of the bent connecting rod, and the other end of the connecting rod 272 can be connected to the middle region of connecting rod 273-a. Alternatively, in other embodiments, the connecting rod 272 can also be connected to the end region of connecting rod 273-a.

[0120] Figure 9The illustration is for informational purposes only and shows a schematic diagram of a transmission assembly 270 between a cover plate 220 and a guide member 260 according to an embodiment of this application. In some other alternative embodiments, by optimizing the bending link 271 and / or the guide member 260, the movement trajectory of the second end 2712 of the bending link 271 can be optimized, thus omitting the link 272 shown in the figure. Alternatively, in other alternative embodiments, the link 273-b, connectors 281 and 282 shown in the figure can be omitted. The bending link 271 can drive one side of the cover plate 220 by driving the link 273-a, and the other side of the cover plate 220 is slidably connected to a limiting structure in the vehicle body structure, so that both sides of the cover plate 220 keep rotating synchronously. Or, in yet another alternative embodiment, the bending link 271 shown in the figure can be replaced by a transmission structure that can change the direction of movement, such as a bevel gear, etc.

[0121] Figure 10 A schematic diagram of yet another lifting device provided in an embodiment of this application is shown. For ease of illustration and explanation, in this… Figure 10 In the illustrated embodiment, decorative and / or functional components carried on the lifting platform 210 are not shown.

[0122] like Figure 10 As shown, in the lifting device 200, the cover plate 220 may include a plate-shaped portion 221 and connecting portions 222-a and 222-b connected to both sides of the plate-shaped portion 221. The first end of the connecting rod 273-a is rotatably connected to the connecting portion 222-a, and the first end of the connecting rod 273-b is rotatably connected to the connecting portion 222-b. Optionally, the connecting portion 222-a may be provided with a guide structure 223-a, which is used to cooperate with the guide structure 292-a connected to the fixed structural member 291-a. Optionally, the connecting portion 222-b may be provided with a guide structure 223-b, which is used to cooperate with the guide structure 292-b connected to the fixed structural member 291-b. When the cover plate 220 is flipped, the guide structure 223-a slides relative to the guide structure 292-a, and the guide structure 223-b slides relative to the guide structure 292-b. Figure 10 In the diagram, for ease of illustration and explanation, fixed structure 291-a and fixed structure 291-b are shown in exploded form. In the assembled state, guide structure 292-a in fixed structure 291-a is slidably connected to guide structure 223-a, and guide structure 292-b in fixed structure 291-b is slidably connected to guide structure 223-b.

[0123] As an example, Figure 10The illustrated guide structures 223-a and 223-b may include sliders, and guide structures 292-a and 292-b may include guide grooves. In other embodiments, the guide structures in the cover plate 220 and the guide structures in the fixing structure may also be other cooperating guide structures, such as shafts and bearings, etc., which are not specifically limited in this application.

[0124] In this embodiment of the application, the fixing structure 291-a and fixing structure 291-b can be fixing components in a vehicle, or the lifting device 200 can include the fixing structure 291-a and fixing structure 291-b, and the two fixing structures can be located in the housing of the lifting device 200.

[0125] In the fixing structure 291-a and fixing structure 291-b, the guiding direction (e.g., the extension direction of the guide groove) of the guide structure 292-a and guide structure 292-b can be adapted to the flipping movement path of the cover plate 220. Specifically, it can be adapted to the movement path of the area where the guide structure 223-a is located in the connecting part 222-a, and the movement path of the area where the guide structure 223-b is located in the connecting part 222-b. Figure 10 The guide structures 292-a and 292-b shown are for illustrative purposes only and are not intended to be limiting. Their shapes can be adapted to the structural design of the cover plate 220, the transmission assembly 270 and the guide member 260, and can also be adapted to the flipping movement path of the cover plate 220. The specific shapes of the guide structures 292-a and 292-b are not limited in this embodiment.

[0126] Through the technical solution of this application embodiment, a matching guide structure can be provided between the cover plate 220 and the fixed connector. On the one hand, the guide structure can provide support for the cover plate 220, thereby improving the stability of the cover plate 220 flipping. On the other hand, through the design of the guide structure, the flipping and moving path of the cover plate 220 can be made more beautiful and smooth, and can be flexibly adapted to different application scenarios and user needs, so as to further improve the aesthetics of the movement of the lifting device 200 and expand its application prospects.

[0127] Optionally, the first end of connecting rod 273-a is rotatably connected to the middle region of connecting portion 222-a, and the first end of connecting rod 273-b is rotatably connected to the middle region of connecting portion 222-b. In this way, connecting rods 273-a and 273-b can effectively move the entire cover plate 220, rather than just a local area of ​​it. Optionally, guide structure 223-a can be located in the end region of connecting portion 222-a away from plate-shaped portion 221, and guide structure 223-b can be located in the end region of connecting portion 222-b away from plate-shaped portion 221. Thus, by guiding the end region of the connecting portion through the guide structure, the flipping shape of the cover plate 220 can be effectively controlled, allowing the shape of the cover plate 220 to reliably adapt to the required application scenario, such as effectively covering a signboard hidden inside a vehicle, thus improving the overall performance of the lifting device 200.

[0128] Alternatively, in some embodiments, such as Figure 4 and Figure 6 As shown, when the lifting platform 210 is in the stroke segment S1, at least a portion of the guide member 260 and the transmission assembly 270 can be located in a first direction of the lifting platform 210, which can be parallel to the y-direction. The cover plate 220 can be located in a second direction of the lifting platform 210, which can be parallel to the z-direction, i.e., the second direction can be perpendicular to the first direction. This facilitates full utilization of the space surrounding the lifting platform 210, allowing for a compact arrangement of the guide member 260, transmission assembly 270, and cover plate 220, thereby improving the space utilization rate of the lifting device 200 and reducing the required volume of space. In some other embodiments, the first and second directions can also be intersecting but not perpendicular directions. Alternatively, in yet another embodiment, the first and second directions can also be parallel directions.

[0129] In some embodiments, such as Figure 7 and Figure 8 As shown, when the lifting platform 210 is in the stroke segment S2 and at its lowest position, compared to the time when the lifting platform 210 is in the stroke segment S1, the cover plate 220 can be flipped from the second direction of the lifting platform 210 to a third direction of the lifting platform 210, which is parallel to the x-direction. Specifically, this third direction can be the top of the lifting platform 210. In other embodiments, the aforementioned third direction can also be an inclined direction intersecting the x-direction at a small angle.

[0130] Optionally, the above embodiment uses the cooperation between the guide member 260 and the transmission assembly 270 as an example to illustrate a transmission method between the lifting platform 210 and the cover plate 220 provided in this application embodiment; in other embodiments, the guide member 260 can be omitted, and a protrusion facing the bending connecting rod can be provided on the lifting platform 210, which can move with the lifting platform 210. The first end 2711 of the bending connecting rod can be connected to an elastic element, such as a spring. When the lifting platform 210 moves in the stroke segment S1, the protrusion is separated from the bending connecting rod; when the lifting platform 210 moves in the stroke segment S2, the protrusion can abut against the bending connecting rod, causing the bending connecting rod to rotate, thereby driving the cover plate 220 to rotate. The provision of the elastic element is beneficial for the automatic reset of the bending connecting rod.

[0131] The above text combined Figures 4 to 10 The illustrated embodiment demonstrates the transmission method between the lifting platform 210 and the cover plate 220 provided in this application embodiment. (Above) Figures 4 to 10 The illustrated embodiment can be compared with Figure 3 The embodiments shown are combined to realize the joint driving of the lifting platform 210 and the cover plate 220 by the driving component 230, thereby realizing the lifting function of the lifting platform 210 and the flipping function of the cover plate 220 in the lifting device 200 provided in this application embodiment.

[0132] Optionally, based on any of the above embodiments, the lifting platform 210 may also be equipped with functional devices to realize anti-theft functions and pedestrian protection functions for the decorative parts and / or functional parts it carries.

[0133] As an example, Figure 11 A schematic diagram of a lifting platform provided in an embodiment of this application is shown. Figure 11 The lifting platform shown can be a schematic exploded view of the lifting platform in any of the embodiments described above.

[0134] like Figure 11 As shown, the lifting platform 210 may include a base portion 211 and a movable portion 212, wherein the movable portion 212 can be used to support decorative parts and / or functional parts, and the movable portion 212 can be connected to the base portion 211 via a snap-fit ​​structure 213, and the base portion 211 is drively connected to the drive member 230. Figure 11 (Not shown in the image). Optionally, in some embodiments, a snap-fit ​​structure 213 may be provided on the movable part 212, and a slot structure 214 may be provided on the base part 211 corresponding to the snap-fit ​​structure 213. Alternatively, in other embodiments, a snap-fit ​​structure 213 may be provided on the base part 211, and a slot structure 214 may be provided on the movable part 212.

[0135] In this embodiment, the lifting platform 210 may be provided with a base portion 211 and a movable portion 212 connected to each other by a snap-fit ​​structure 213. When the base portion 211 and the movable portion 212 are connected, the drive member 230 can drive the base portion 211 to drive the entire base portion 211 and the movable portion 212, i.e., the lifting platform 210, to move up and down. When the decorative parts and / or functional parts carried on the movable portion 212 are subjected to a certain external force (e.g., greater than a first force), the snap-fit ​​structure 213 on the movable portion 212 can disengage from the slot structure 214 on the base portion 211. The movable portion 212 can then descend into the interior space of the vehicle under the action of gravity, thereby protecting the decorative parts and / or functional parts carried on the movable portion 212 and providing anti-theft and pedestrian protection functions.

[0136] Optionally, the movable part 212 may be provided with a through hole 215 extending along the x-direction, thereby facilitating the passage of the guide member 250. When the movable part 212 is detached from the base part 211, the movable part 212 can descend along the extension direction of the guide member 250, resulting in better stability and controllability during the descent of the movable part 212. Optionally, the base part 211 may be provided with a through hole 216 extending along the x-direction, thereby facilitating the passage of the guide member 250. When the driving member 230 drives the base part 211, the base part 211 can move up and down along the extension direction of the guide member 250. When the base part 211 and the movable part 212 are assembled together, the through hole 215 in the movable part 212 can communicate with the through hole 216 in the base part 211, and the two are coaxially arranged.

[0137] exist Figure 11 In the illustrated embodiment, the movable part 212 and the base part 211 can be detachably connected via the snap-fit ​​structure 213. The magnitude of the force required for the movable part 212 to detach from the base part 211 can be controlled by setting the interference amount between the snap-fit ​​structure 213 and the slot structure 214. The interference amount between the snap-fit ​​structure 213 and the slot structure 214 can be the size of a local area of ​​the snap-fit ​​structure 213 within the slot structure 214 in the insertion direction when they are connected; for example, in... Figure 11 In the illustrated embodiment, the insertion direction can be the z-direction. In other embodiments, the insertion direction of the snap-fit ​​structure 213 can also be any direction in the yz plane.

[0138] In this embodiment, the snap-fit ​​structure 213 allows the movable part 212 to detach from the base part 211 when the decorative part and / or functional part carried on the movable part 212 is subjected to a downward or tilted downward external force. Conversely, when the decorative part and / or functional part carried on the movable part 212 is subjected to an upward or tilted upward external force, the snap-fit ​​structure 213 enhances the movable part 212's resistance to external forces, thereby reducing the risk of theft of the decorative part and / or functional part. Optionally, the upper and lower surfaces of the snap-fit ​​structure 213 can be configured with different structures and / or shapes to adapt to different responses of the movable part 212 to upward and downward forces.

[0139] Alternatively, in addition to the snap-fit ​​structure 213, the movable part 212 and the base part 211 can be detachably connected, or they can be detachably connected by other detachable structures, such as magnetic structures, detachable adhesive structures, etc.

[0140] In the above embodiments, the movable part 212 can be detached from the base part 211 under external force through a detachable structure such as the snap-fit ​​structure 213, thereby achieving functions such as anti-theft. In other embodiments, a force sensor can be installed in the lifting platform 210, which can be used to detect the external force on the decorative parts and / or functional parts. The force sensor and the drive unit 230 can be electrically connected to a control device in the vehicle, which can control the drive unit 230 according to the detection signal of the force sensor. As an example, when the force indicated by the detection signal of the force sensor is greater than a first value, the control device can control the drive unit 230 to drive the lifting platform 210 to descend. The first value can be flexibly set according to needs, and this application embodiment does not specifically limit it. In this way, the lifting device 200 can realize the automatic descent of the lifting platform 210 through the cooperation of the force sensor, the control device, and the drive unit, thereby protecting the decorative parts and / or functional parts carried on the lifting platform 210, and playing functions such as anti-theft and pedestrian protection.

[0141] Optionally, such as Figure 11 As shown, the force sensor can be installed in the support portion 217 of the lifting platform 210 for supporting decorative parts and / or functional parts. The support portion 217 can be connected to the rigid structure of the lifting platform 210 via an elastic connector. In this way, when the decorative parts and / or functional parts are subjected to external forces, the elastic connector can provide a certain buffering effect for the support portion 217, thereby improving the stability of the force sensor in detecting external forces and also helping to protect the force sensor.

[0142] Optionally, in the above embodiments, the force sensor may be disposed on the lifting platform 210; or, in some other embodiments, the force sensor may be disposed on the decorative parts and / or functional parts carried by the lifting platform 210; or, in yet another embodiment, the force sensor may be disposed on both the lifting platform 210 and the decorative parts and / or functional parts.

[0143] Optionally, if a force sensor is provided in the lifting device 200, the main body of the lifting platform 210 can be configured as a single unit, or alternatively, it can be... Figure 11 The embodiment shown includes a detachably connected movable part 212 and a base part 211. When the lifting platform 210 is equipped with a force sensor and also includes the movable part 212 and the base part 211, it can better achieve multi-dimensional protection of decorative parts and / or functional parts, anti-theft functions, and pedestrian protection functions.

[0144] Optionally, the lifting device 200 may be equipped with a sensor for detecting that the movable part 212 is detached from the base part 211. When the movable part 212 is detached from the base part 211, the controller may acquire the signal from the sensor and control the drive to drive the base part 211 to descend, so that the base part 211 can be reconnected to the movable part 212.

[0145] Figure 12 and Figure 13 Schematic diagrams of two more lifting devices provided in embodiments of this application are shown.

[0146] like Figure 12 and Figure 13 As shown, the lifting device 200 may further include a housing 201, in which at least a portion of other components of the lifting device 200 are housed. The wall of the housing 201 may form an opening 202, through which decorative elements and / or functional components carried by the lifting platform 210 can move outside the housing 201 when the lifting platform 210 rises; similarly, through the opening 202, the decorative elements and / or functional components carried by the lifting platform 210 can move inside the housing 201 when the lifting platform 210 descends.

[0147] like Figure 12 As shown, when the lifting platform 210 in the lifting device 200 is in its highest position, the decorative and / or functional components it carries (e.g., Figure 12 The sign 101 shown may be located outside the housing 201. Furthermore, the decorative and / or functional components may be located in the external space of the vehicle. The cover 220 in the lifting device 200 may be located inside the housing 201.

[0148] like Figure 13As shown, when the lifting platform 210 in the lifting device 200 is in its lowest position, the decorative and / or functional components it carries can be located within the housing 201. Furthermore, the cover plate 220 in the lifting device 200 can be located outside the housing 201, and more specifically, the cover plate 220 can be located in the external space of the vehicle.

[0149] In this embodiment, the housing 201 facilitates the installation of the lifting device 200 in a vehicle. Furthermore, the housing 201 can better protect the lifting platform 210, cover plate 220, drive component 230 and multiple transmission components in the lifting device 200, thereby improving the structural reliability of the lifting device 200.
