Description

Technical Field

[0001] This invention relates to the field of automotive logo technology, specifically to a linkage-type lifting logo device. Background Technology

[0002] With the development of the automotive industry and the improvement of consumer aesthetics, the design of car logos at the front of vehicles is no longer limited to static decorative functions, but has gradually evolved into an important element reflecting the brand's technological feel and personalization. Retractable car logos have emerged as a result. They can automatically rise when the vehicle starts, is in motion, or in specific scenarios, and automatically retract and hide when the engine is turned off or in the event of a collision. This design not only enhances the dynamic visual effect and sense of ceremony of the vehicle, but more importantly, it provides a safety consideration: in the event of a pedestrian collision, a retractable car logo can effectively reduce the risk of secondary injury to pedestrians, thus improving passive safety.

[0003] Most retractable car emblems leave an opening or dent on the vehicle's surface that doesn't match the surrounding grille design after retracting, ruining the overall aesthetics and design integrity of the vehicle's front end. Furthermore, the exposed opening easily accumulates dust, debris, or rainwater during driving, potentially intruding into the emblem's drive mechanism, causing jamming, wear, or corrosion, affecting its long-term reliability. To achieve the function of concealing the opening after the emblem is raised, some advanced solutions use a separate cover with its own dedicated drive motor and control unit. This results in a complex system structure and an increased number of parts, increasing manufacturing costs and failure rates, as well as requiring more space. More importantly, the raising and lowering of the emblem and the opening and closing of the cover require precise electronic sensors for position detection and rely on complex control programs to synchronize their actions. Under the complex electromagnetic environment and long-term vibration conditions of a car, sensor signals may be interfered with, and the control program may malfunction, leading to disordered actions. For example, the cover may close prematurely before the emblem is fully retracted, causing interference and damage, severely impacting the system's reliability and durability. Summary of the Invention

[0004] The purpose of this invention is to provide a linkage-type lifting logo device that can improve safety, enhance aesthetics, achieve highly integrated single-power-source drive, and establish a reliable and direct mechanical linkage relationship.

[0005] A linkage-type lifting vehicle emblem device, comprising: The substrate has an opening on it; The car logo module can extend or retract into the base; A drive assembly for driving itself and the car logo module to move relative to the base along a preset trajectory; A shielding structure for closing or exposing the opening; A linkage transmission mechanism is movably disposed within the base body; When the drive assembly and the logo module move to a preset linkage position, the housing part of the drive assembly contacts the linkage transmission mechanism and drives it to move, so that the downward movement of the logo module drives the shielding mechanism to shield the opening, and the upward movement of the logo module allows or drives the shielding mechanism to reset.

[0006] In the above solution, the drive assembly provides power, enabling the logo module to extend or retract within the base. When the logo module reaches a specific linkage position, the interaction between the housing of the drive assembly and the linkage transmission mechanism achieves the linkage between the lifting and lowering movement of the logo module and the opening and closing action of the shielding structure. This purely mechanical linkage method does not rely on electronic sensor signal synchronization or additional control logic, fundamentally avoiding the problem of disordered action caused by signal interference, program errors, or independent actuator failures. In the event of a vehicle collision, the retractable logo module can reduce the risk of secondary injury to pedestrians. After the logo module descends, the shielding structure can close the opening, reducing the possibility of external objects entering the base and damaging the logo module and related mechanisms, while maintaining the overall aesthetics and integrity of the vehicle's appearance. The lifting and lowering function of the logo module and its linkage with the shielding structure also add a unique dynamic display effect to the vehicle. Achieving the linkage between the lifting and lowering movement of the logo module and the opening and closing action of the shielding structure through a single drive assembly and linkage transmission mechanism simplifies the system structure, reduces costs, and improves the reliability and stability of the device.

[0007] Furthermore, the linkage transmission mechanism includes a rotating arm, the rotating arm and the base forming a first rotating pair through a first rotating shaft, the shielding structure forming a second rotating pair through a second rotating shaft, one end of the rotating arm being slidably connected to the sliding groove of the shielding structure, and the drive assembly being configured to contact the other end of the rotating arm in the linkage position to drive the rotating arm to move around the first rotating shaft.

[0008] In the above scheme, when the drive assembly and the logo module descend to the linkage position, the housing of the drive assembly will contact one end of the rotating arm. The thrust generated by the continued descent of the drive assembly will cause the rotating arm to move around the first rotating shaft. During the rotation of the rotating arm, it will slide and engage with the sliding groove of the shielding structure, so that the shielding structure rotates around the second rotating shaft and gradually closes until the logo module descends to the position and the opening is completely blocked. When the logo module needs to rise, the drive assembly will drive itself and the logo module to rise along a preset trajectory. The rotating arm will rotate in the opposite direction to reset, which will drive the shielding structure to rotate in the opposite direction. When the linkage position is reached, the shielding structure and the rotating arm are reset, the opening is exposed, and the logo module gradually extends from the opening until it moves to the position. The pure mechanical linkage method does not rely on electronic sensors and complex control programs to achieve the synchronization of the lifting and lowering of the logo module and the opening and closing of the shielding structure. This avoids the loss of control or uncoordinated action caused by electronic signal interference, program failure or sensor failure. Compared with the design of using multiple independent drives and complex control systems, this simplified structure reduces the number of parts and reduces the complexity of the system.

[0009] Furthermore, it also includes an elastic reset element, one end of which is connected to the rotating arm at a position between the first rotating shaft and the second rotating shaft, and the other end is connected to the base, for providing the rotating arm with an elastic force to drive the shielding structure to reset.

[0010] In the above scheme, during the process of the car logo module rising, the elastic reset element can provide a stable and reliable elastic force to drive the rotating arm to reset, thereby driving the shielding structure to reset so that the opening is exposed, allowing the car logo module to extend smoothly out of the base. This helps to simplify the system structure, reduce costs, and also improve the reliability and stability of the device.

[0011] Furthermore, the drive assembly includes a drive member, a gearbox assembly, and at least one output gear. The drive end of the drive member is connected to the input shaft of the gearbox assembly, and the output gear is connected to the output shaft of the gearbox assembly. The drive member drives the gearbox assembly to move, so that the output gear moves along a preset trajectory within the base.

[0012] In the above scheme, when the drive unit starts, it generates a driving torque and transmits this torque to the input shaft of the gearbox assembly, thereby causing the input shaft to rotate. The rotation of the input shaft drives a series of gear mechanisms inside the gearbox assembly. These gear mechanisms operate according to the designed transmission ratio, adjusting the input speed and torque. By rationally designing the number of teeth and meshing method of the gears, the gearbox assembly can optimize the power provided by the drive unit to meet the specific requirements of the car logo module's lifting and lowering movement. The power adjusted by the gearbox assembly is transmitted to the output gear through the output shaft, causing the output gear to rotate. Since the output gear cooperates with the preset trajectory in the base, it drives the entire drive assembly and the connected car logo module to move relative to the base along the preset trajectory, thereby realizing the extension or retraction of the car logo module.

[0013] Furthermore, at least one track plate is installed in the base, the track plate is provided with a track groove and a moving groove spaced apart from the track groove, a transmission rack is provided in the track groove, the output gear meshes with the transmission rack, the housing part of the drive assembly is provided with a guide part, the guide part slides with the moving groove, when the drive assembly moves, the output gear moves along the transmission rack and drives the entire drive assembly to move, and the guide part slides along the moving groove.

[0014] In the above solution, during the lifting and lowering process of the logo module, the gear transmission method between the output gear and the transmission rack ensures that the output gear moves at the set speed and displacement, thereby driving the drive assembly and the logo module to move smoothly and accurately, reducing motion errors and vibrations. The sliding cooperation between the guide part and the moving groove provides precise guidance for the movement of the drive assembly. The shape and position of the moving groove are preset, which can strictly limit the drive assembly to move only along a specific trajectory. This ensures the accuracy of the path of the logo module during the lifting and lowering process, enabling the logo to accurately extend and retract to the predetermined position, improving the accuracy and consistency of the logo display, and avoiding problems such as inaccurate logo position or interference with surrounding components caused by motion deviation.

[0015] Furthermore, the track groove includes a straight section and a curved section, and the transmission rack is provided with a straight toothed portion and a curved toothed portion. The length direction of the track groove is parallel to the straight portion, and the bottom end of the track groove is flush with the bottom end of the straight section. When the output gear enters the curved section from the straight section, the drive assembly swings with the contact point of its guide portion in the moving groove as the rotation center.

[0016] In the above scheme, when the drive assembly drives the logo module to move along the straight section of the track groove, since the transmission rack in the straight section has straight teeth, when the output gear meshes with the straight teeth, it will drive the drive assembly to make translational motion along the straight track. At this time, the guide part slides linearly in the moving groove, and the drive assembly as a whole smoothly drives the logo module to move in the straight direction. The logo module may be in a state of upward or downward linear motion. When the output gear enters the curved section from the straight section, the situation changes. The transmission rack in the curved section has curved teeth, and the output gear meshes with the curved teeth. The direction of the force on the output gear is no longer along the straight direction, but will generate a lateral component force. At the same time, the guide part still plays a constraining role in the moving groove. At this time, the drive assembly will swing with the contact point of its guide part in the moving groove as the rotation center. This swing causes the drive assembly and the logo module connected to it to change direction during the movement, so that the logo module swings away from the linkage transmission mechanism. This can avoid the logo module from rigidly colliding with surrounding parts during the movement and improve space utilization.

[0017] Furthermore, the moving groove is an elongated hole extending along the straight section of the trajectory groove, and the guide portion is provided with a pin that slides with the elongated hole.

[0018] In the above scheme, when the drive assembly is working, the pin slides in the elongated hole, which strictly limits the guide part to move only along the direction of the elongated hole. This ensures that the entire drive assembly and the car logo module connected to it can achieve precise linear motion. When the drive assembly moves to the curved section of the track groove, the pin can ensure that the drive assembly swings around the pin as the rotation center. The structure of the elongated hole and the pin is simple, which not only facilitates manufacturing and installation, but also reduces the possible failure points due to too many parts, and improves the reliability and stability of the entire car logo device.

[0019] Furthermore, the linkage position is located within the curved segment of the track groove. When the output gear enters the curved segment and drives the drive assembly to swing, the housing part of the drive assembly contacts the rotating arm and pushes it to rotate, so that the shielding structure closes the opening.

[0020] In the above scheme, when the output gear enters the curved section of the track groove and drives the drive assembly to swing, the drive assembly housing can automatically push the rotating arm to rotate, thereby closing the opening of the shielding structure. This design makes the swing of the drive assembly and the rotation of the shielding structure form an effective linkage, making full use of the power and motion characteristics of the existing moving parts, avoiding the need to add a complex drive device to achieve the shielding function, and improving the operating efficiency and space utilization of the entire system.

[0021] Furthermore, there are two track boards, which are symmetrically arranged on both sides of the drive assembly.

[0022] In the above scheme, the two symmetrically arranged track plates can provide more precise guidance for the movement of the drive assembly. When the output gear moves in the track groove and the guide part slides along the moving groove, the track plates on both sides simultaneously constrain and guide it, making the linear motion and oscillation of the drive assembly more stable and accurate. Compared with a single track plate, the design of dual track plates can better resist the influence of lateral forces and torque, reduce deviations and shaking during the movement, and ensure that components connected to the drive assembly, such as the logo module, can move according to the preset trajectory and posture, thus improving the motion accuracy of the entire system. During the movement of the drive assembly, the force exerted by the track plates on both sides on the output gear is uniform and consistent, avoiding the problem of asynchronous movement caused by uneven force on both sides. This synchronization can make the lifting and oscillation movements of the logo module more coordinated.

[0023] Furthermore, a drive protrusion is provided on the housing portion of the drive assembly. The drive protrusion is triangular or wedge-shaped and is used to contact the linkage transmission mechanism at the linkage position.

[0024] In the above scheme, the inclined or wedge-shaped surface of the triangle can make smooth, gradual contact with the rotating arm when the drive assembly moves to the linkage position. This avoids rigid impact and converts the linear or oscillating kinetic energy of the drive assembly into a tangential force that drives the rotating arm to rotate more efficiently and smoothly. This reduces noise, vibration, and wear at the moment of contact and improves the smoothness of the movement and the life of the mechanism. When the drive assembly and the logo module move, the position of the contact point between the drive protrusion and the rotating arm will change continuously along the inclined surface. This design realizes the function of a mechanical position and angle converter, mapping the precise composite displacement of the drive assembly to the rotation angle determined by the rotating arm. This allows for precise control of the opening and closing angle and timing of the shielding structure, ensuring that the shielding action is strictly matched with the lifting and lowering stroke of the logo.

[0025] The linkage lifting logo device of the present invention has the beneficial effects of improving safety, enhancing aesthetics, realizing highly integrated single power source drive and establishing a reliable and direct mechanical linkage relationship. Powered by a drive assembly, the logo module can extend or retract within the base. When the logo module reaches a specific linkage position, the interaction between the drive assembly's housing and the linkage transmission mechanism enables the logo module's lifting and lowering movement to synchronize with the opening and closing of the shielding structure. This purely mechanical linkage method does not rely on electronic sensor signal synchronization or additional control logic, fundamentally avoiding the problem of disordered action caused by signal interference, program errors, or independent actuator failures. In the event of a vehicle collision, the retractable logo module reduces the risk of secondary injury to pedestrians. After the logo module descends, the shielding structure closes the opening, reducing the possibility of external objects entering the base and damaging the logo module and related mechanisms, while maintaining the overall aesthetics and integrity of the vehicle's appearance. The logo module's lifting and lowering function and its linkage with the shielding structure also add a unique dynamic display effect to the vehicle. Achieving the linkage between the logo module's lifting and lowering movement and the shielding structure's opening and closing through a single drive assembly and linkage transmission mechanism simplifies the system structure, reduces costs, and improves the device's reliability and stability.

[0033] The following will provide a more detailed description of a linkage lifting vehicle emblem device according to the present invention, in conjunction with specific embodiments and accompanying drawings.

[0034] like Figures 1 to 3 As shown in a preferred embodiment, a linkage lifting car emblem device of the present invention includes: a base 2, a car emblem module 3, a drive assembly 4, a shielding structure 6, and a linkage transmission mechanism 5. The base 2 is provided with an opening 1, and the car emblem module 3 can extend or retract into the base 2. The drive assembly 4 is used to drive itself and the car emblem module 3 to move relative to the base 2 along a preset trajectory. The shielding structure 6 is used to close or expose the opening 1. The linkage transmission mechanism 5 is movably disposed within the base 2. When the drive assembly 4 and the car emblem module 3 move to a preset linkage position, the housing part of the drive assembly 4 contacts the linkage transmission mechanism 5 and drives it to move, so that the downward movement of the car emblem module 3 drives the shielding mechanism to shield the opening 1, and the upward movement of the car emblem module 3 allows or drives the shielding mechanism to reset.

[0035] Reference Figures 5 to 6The drive assembly 4 provides power, enabling the logo module 3 to extend or retract within the base 2. When the logo module 3 reaches a specific linkage position, the housing of the drive assembly 4 interacts with the linkage transmission mechanism 5 to link the lifting and lowering movement of the logo module 3 with the opening and closing action of the shielding structure 6. When the logo module 3 needs to descend, the drive assembly 4 drives itself and the logo module 3 to move relative to the base 2 along a preset trajectory. As the logo module 3 continues to descend, when it reaches the preset linkage position, the housing of the drive assembly 4 contacts the linkage transmission mechanism 5. At this point, the force generated by the continued descent of the drive assembly 4 is transmitted to the linkage transmission mechanism 5, causing it to begin moving. The movement of the linkage transmission mechanism 5 then drives the shielding structure. Action 6 causes the shielding structure 6 to gradually close the opening 1 on the base 2 until the logo module 3 descends to its final position, completely shielding the opening 1. When the logo module 3 needs to rise, the drive assembly 4 provides power again, driving itself and the logo module 3 to rise along a preset trajectory. During this process, the linkage transmission mechanism 5, which had stored a certain amount of potential energy when the logo module 3 descended, releases its potential energy when the logo module 3 rises, driving itself to continue moving. The movement of the linkage transmission mechanism 5 will then cause the shielding structure 6 to move in the opposite direction, gradually opening the opening 1 and exposing the interior of the base 2. When the logo module 3 leaves the linkage position, the shielding structure 6 completes its reset, and the opening 1 is fully exposed. Afterward, the drive assembly 4 continues to drive it and the logo module 3 to move, causing the logo module 3 to rise to its final position.

[0036] This purely mechanical linkage method does not rely on electronic sensor signal synchronization or additional control logic, fundamentally avoiding the problem of disordered action caused by signal interference, program errors, or independent actuator failure. In the event of a vehicle collision, the retractable logo module 3 within the base 2 can reduce the risk of secondary injury to pedestrians. Compared to traditional fixed logos, this liftable design prevents the logo from directly impacting pedestrians like a sharp protrusion during a collision, thus protecting pedestrian safety to a certain extent. After the logo module 3 descends, the shielding structure 6 can close the opening 1, reducing the possibility of external objects entering the base 2 and damaging the logo module 3 and related mechanisms, while maintaining the overall aesthetics and integrity of the vehicle's appearance. The liftable function of the logo module 3 and its linkage with the shielding structure 6 also add a unique dynamic display effect to the vehicle. The linkage between the lifting movement of the logo module 3 and the opening and closing movement of the shielding structure 6 is achieved through a drive assembly 4 and a linkage transmission mechanism 5, simplifying the system structure, reducing costs, and improving the reliability and stability of the device.

[0037] like Figure 3As shown, in some embodiments, the linkage transmission mechanism 5 includes a rotating arm 51, the rotating arm 51 and the base 2 forming a first rotating pair through a first rotating shaft 52, the shielding structure 6 forming a second rotating pair through a second rotating shaft 53, one end of the rotating arm 51 being slidably connected to the sliding groove 61 of the shielding structure 6, and the drive assembly 4 being configured to contact the other end of the rotating arm 51 in the linkage position to drive the rotating arm 51 to move around the first rotating shaft 52. When the drive assembly 4 and the logo module 3 descend to the linkage position, the housing of the drive assembly 4 will contact one end of the rotating arm 51. The thrust generated by the continued descent of the drive assembly 4 will cause the rotating arm 51 to move around the first rotating shaft 52. During the rotation of the rotating arm 51, it will slide and engage with the sliding groove 61 of the shielding structure 6, thereby causing the shielding structure 6 to rotate around the second rotating shaft 53 and gradually close the opening 1 until the logo module 3 has descended to its final position, and the opening 1 is completely covered by the shielding cover 62 of the shielding structure 6. When the logo module 3 needs to rise, the drive assembly 4 will drive itself and the logo module 3 to rise along a preset trajectory, and the rotating arm 51 will reverse. The rotation resets the shielding structure 6, causing it to rotate in the opposite direction. When the linkage position is reached, the shielding structure 6 and the rotating arm 51 are reset, the opening 1 is exposed, and the logo module 3 gradually extends out of the opening 1 until it reaches its position. The purely mechanical linkage method eliminates the need for electronic sensors and complex control programs to synchronize the lifting and lowering of the logo module 3 with the opening and closing of the shielding structure 6. This avoids uncontrolled or uncoordinated movements caused by electronic signal interference, program failures, or sensor malfunctions. Compared to designs using multiple independent drives and complex control systems, this simplified structure reduces the number of parts and lowers the complexity of the system.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments, an elastic reset element 54 is also included. One end of the elastic reset element 54 is connected to the rotating arm 51 at a position between the first rotating shaft 52 and the second rotating shaft 53, and the other end is connected to the base 2. It is used to provide the rotating arm 51 with an elastic force to drive the shielding structure 6 to reset. During the rising process of the logo module 3, the elastic reset element 54 can provide a stable and reliable elastic force to drive the rotating arm 51 to reset, thereby driving the shielding structure 6 to reset so that the opening 1 is exposed, allowing the logo module 3 to smoothly extend out of the base 2. The elastic reset element 54 can be a tension spring, which helps to simplify the system structure, reduce costs, and also improve the reliability and stability of the device.

[0039] like Figure 3 and Figure 4As shown, in some embodiments, the drive assembly 4 includes a drive member, a gearbox assembly, and at least one output gear 41. The drive end of the drive member is connected to the input shaft of the gearbox assembly, and the output gear 41 is connected to the output shaft of the gearbox assembly. The drive member drives the gearbox assembly to move, so that the output gear 41 moves along a preset trajectory within the base 2. When the drive member is activated, it generates a driving torque and transmits this torque to the input shaft of the gearbox assembly, thereby causing the input shaft to start rotating. The rotation of the input shaft will drive a series of gear mechanisms inside the gearbox assembly to move. The drive member and gearbox assembly can adopt conventional structures. These gear mechanisms operate according to the designed transmission ratio, adjusting the input speed and torque. By rationally designing the number of teeth and meshing method of the gears, the gearbox assembly can optimize the power provided by the drive component to meet the specific requirements of the lifting and lowering movement of the logo module 3. The power adjusted by the gearbox assembly is transmitted to the output gear 41 through the output shaft, causing the output gear 41 to start rotating. Since the output gear 41 cooperates with the preset trajectory in the base 2, it will drive the entire drive assembly 4 and the logo module 3 connected to it to move relative to the base 2 along the preset trajectory, thereby realizing the extension or retraction of the logo module 3.

[0040] like Figure 3 and Figure 4 As shown, in some embodiments, at least one track plate 7 is installed in the base 2. The track plate 7 is provided with a track groove 71 and a moving groove 73 spaced apart from the track groove 71. A transmission rack is provided in the track groove 71. The output gear 41 meshes with the transmission rack. The housing part of the drive assembly 4 is provided with a guide part 42. The guide part 42 is slidably engaged with the moving groove 73. When the drive assembly 4 moves, the output gear 41 moves along the transmission rack and drives the drive assembly 4 to move as a whole. The guide part 42 slides along the moving groove 73. During the lifting and lowering process of the logo module 3, the gear transmission between the output gear 41 and the transmission rack ensures that the output gear 41 moves at the set speed and displacement, thereby driving the drive assembly 4 and the logo module 3 to move smoothly and accurately, reducing motion errors and vibrations. The sliding cooperation between the guide part 42 and the moving groove 73 provides precise guidance for the movement of the drive assembly 4. The shape and position of the moving groove 73 are preset, which can strictly limit the drive assembly 4 to move only along a specific trajectory. This ensures the accuracy of the path of the logo module 3 during the lifting and lowering process, so that the logo can be accurately extended and retracted to the predetermined position, improving the accuracy and consistency of the logo display, and avoiding problems such as inaccurate logo position or interference with surrounding components caused by motion deviation.

[0041] like Figure 3 and Figure 4As shown, in some embodiments, the track groove 71 includes a straight section 711 and a curved section 712. The transmission rack is provided with a straight toothed portion 721 and a curved toothed portion 722. The length direction of the track groove 71 is parallel to the straight portion, and the bottom end of the track groove 71 is flush with the bottom end of the straight section 711. When the output gear 41 enters the curved section 712 from the straight section 711, the drive assembly 4 swings with the contact point of its guide portion 42 in the moving groove 73 as the rotation center. When the drive assembly 4 drives the logo module 3 to move along the straight section 711 of the track groove 71, since the transmission rack in the straight section 711 has a straight toothed portion 721, when the output gear 41 meshes with the straight toothed portion 721, it will drive the drive assembly 4 to make a translational motion along the straight track. At this time, the guide portion 42 slides linearly in the moving groove 73, and the drive assembly 4 as a whole smoothly drives the logo module 3 to move in a straight direction. The logo module 3 may be in a state of upward or downward linear motion. When the output gear 41 enters the curved section 712 from the straight section 711, the situation changes. The transmission rack in the curved section 712 has a curved toothed portion 722, and the output gear 41... When meshing with the curved tooth 722, the force on the output gear 41 is no longer in a straight line, but generates a lateral component force. At the same time, the guide part 42 still plays a constraining role in the moving groove 73. At this time, the logo module 3 has been retracted into the base 2. The drive assembly 4 will swing with the contact point of its guide part 42 in the moving groove 73 as the rotation center. This swing causes the drive assembly 4 and the logo module 3 connected to it to change direction during the movement, so that the logo module 3 swings away from the linkage transmission mechanism 5. This can avoid the logo module 3 from rigidly colliding with surrounding parts during the movement and improve space utilization.

[0042] like Figure 3 and Figure 4 As shown, in some embodiments, the moving groove 73 is an elongated hole extending along the straight section 711 of the track groove 71, and the guide part 42 is provided with a pin that slides in conjunction with the elongated hole. When the drive assembly 4 is working, the pin slides in the elongated hole, strictly limiting the guide part 42 to move only along the direction of the elongated hole, thereby ensuring that the entire drive assembly 4 and the car logo module 3 connected to it can achieve precise linear motion. When the drive assembly 4 moves to the curved section 712 of the track groove 71, the pin can ensure that the drive assembly 4 swings around the pin as the rotation center. The structure of the elongated hole and the pin is simple, which not only facilitates manufacturing and installation, but also reduces the possible failure points due to too many parts, and improves the reliability and stability of the entire car logo device.

[0043] like Figures 5 to 6As shown, in some embodiments, the linkage position is located within the curved segment 712 of the track groove 71. When the output gear 41 enters the curved segment 712 and drives the drive assembly 4 to swing, the housing part of the drive assembly 4 contacts the rotating arm 51 and pushes it to rotate, so that the shielding structure 6 closes the opening 1. When the output gear 41 enters the curved segment 712 of the track groove 71 and drives the drive assembly 4 to swing, the housing part of the drive assembly 4 can automatically push the rotating arm 51 to rotate, thereby causing the shielding structure 6 to close the opening 1. This design makes the swing of the drive assembly 4 and the rotation of the shielding structure 6 form an effective linkage, making full use of the power and motion characteristics of the existing moving parts, avoiding the need to add a complex drive device to achieve the shielding function, and improving the operating efficiency and space utilization of the entire system.

[0044] like Figure 3 As shown, in some embodiments, there are two track plates 7, symmetrically arranged on both sides of the drive assembly 4. The two symmetrically arranged track plates 7 provide more precise guidance for the movement of the drive assembly 4. When the output gear 41 moves within the track groove 71 and the guide part 42 slides along the moving groove 73, the track plates 7 on both sides simultaneously constrain and guide it, making the linear motion and oscillation of the drive assembly 4 more stable and accurate. Compared to a single track plate 7, the design of dual track plates 7 can better resist the influence of lateral forces and torque, reducing deviations and swaying during movement. This ensures that components connected to the drive assembly 4, such as the logo module 3, can move according to the preset trajectory and posture, improving the overall system's motion accuracy. During the movement of the drive assembly 4, the force exerted by the track plates 7 on the output gear 41 is uniform and consistent, avoiding the problem of asynchronous movement caused by uneven force on both sides. This synchronization makes the lifting and oscillating movements of the logo module 3 more coordinated.

[0045] like Figure 5 and Figure 6 As shown, in some embodiments, a drive protrusion 43 is provided on the housing portion of the drive assembly 4. The drive protrusion 43 is triangular or wedge-shaped and is used to contact the linkage transmission mechanism 5 in the linkage position. The inclined surface of the triangle or the wedge-shaped surface can make smooth, gradual contact with the rotating arm 51 when the drive assembly 4 moves to the linkage position. This avoids rigid impact and converts the linear or oscillating kinetic energy of the drive assembly 4 into a tangential force that drives the rotating arm 51 to rotate more efficiently and smoothly. This reduces noise, vibration and wear at the moment of contact and improves the smoothness of the movement and the life of the mechanism. When the drive assembly 4 and the logo module 3 move, the position of the contact point between the drive protrusion 43 and the rotating arm 51 will change continuously along the inclined surface. This design realizes the function of a mechanical position and angle converter, mapping the precise composite displacement of the drive assembly 4 to the determined rotation angle of the rotating arm 51, thereby precisely controlling the opening and closing angle and timing of the shielding structure 6 and ensuring that the shielding action is strictly matched with the lifting stroke of the logo.

[0046] like Figures 1 to 3 As shown, in this embodiment, the base 2 constitutes the mounting frame and outer shell of the entire device. The base 2 mainly includes two parts: a base 21 and a top cover 22. The two parts are fixedly connected by screws, clips, or welding to form a box structure with internal storage space. Specifically, the base 21 is usually made of metal or high-strength engineering plastic, and its core design is to provide a stable mounting base. The bottom or side of the base 21 is provided with multiple mounting lugs or threaded holes for rigidly fixing the entire car logo device to the front crossbeam or grille frame of the car with fasteners such as bolts. The base 21 is provided with bearing seats or bearing holes for mounting the first rotating shaft 52 and the second rotating shaft 53 to ensure the precise rotation center position of the rotating arm 51 and the shielding cover 62. In addition, the positioning post or mounting groove for mounting the track plate 7 is also integrally formed or machined on the inner wall of the base 21. The top cover 22, as an appearance part and protective cover, is usually made of plastic or composite material that coordinates with the appearance of the car body. The inner side of the top cover 22 is connected to the base 21, together enclosing the movement space of components such as the shielding structure 6 and the rotating arm 51. With two track plates 7, the inner wall of the top cover 22 is also machined or integrally formed with positioning posts or mounting grooves for mounting the track plates 7.

[0047] The working principle and process of the linkage lifting car logo device of the present invention are as follows: When the car logo module 3 needs to be lowered, the drive assembly 4 will drive itself and the car logo module 3 to move along the preset trajectory relative to the base 2. As the car logo module 3 continues to fall, when it moves to the preset linkage position, the housing part of the drive assembly 4 will contact the linkage transmission mechanism 5. At this time, the car logo module 3 retracts into the base 2. The force generated by the drive assembly 4 continuing to fall will be transmitted to the linkage transmission mechanism 5, causing it to start moving. The movement of the linkage transmission mechanism 5 will then drive the shielding structure 6 to move, so that the shielding structure 6 gradually closes the opening 1 on the base 2 until the car logo module 3 falls to the position and the opening 1 is completely shielded. When the logo module 3 needs to rise, the drive assembly 4 provides power again, driving itself and the logo module 3 to rise along the preset trajectory. During this process, the linkage transmission mechanism 5, which had stored a certain amount of potential energy when the logo module 3 was descending, will release the potential energy when the logo module 3 rises, driving itself to continue moving. The movement of the linkage transmission mechanism 5 will also drive the shielding structure 6 to move in the opposite direction, causing it to gradually open the opening 1 and expose the interior of the base 2. When the logo module 3 leaves the linkage position, the shielding structure 6 completes its reset, and the opening 1 is fully exposed. Then the drive assembly 4 continues to drive it and the logo module 3 to move, so that the logo module 3 rises to the correct position.
