[0039] The present application provides a trigger force adjustment mechanism, a vehicle logo lifting device and a vehicle. The trigger force adjustment mechanism includes an adjustment component and a position holding component. The adjustment component includes a lever arm adjustment disk, a guide seat and a plurality of sliding parts. The lever arm adjustment disk is used to support the three-dimensional vehicle logo. The bottom of the lever arm adjustment disk is provided with a plurality of groove structures distributed along the circumferential interval around the central axis of the lever arm adjustment disk. The guide seat is assembled at the bottom of the lever arm adjustment disk and is used to assemble a plurality of sliding parts. The top of each sliding part extends upward relative to the guide seat and is connected to the corresponding groove structure in a limiting manner. The position holding component is assembled at the bottom of the sliding part and the guide seat and is connected to the clutch mechanism. The trigger force adjustment mechanism is configured to adjust the trigger force of the unlocking clutch mechanism.

[0040] The trigger force adjustment mechanism, vehicle logo lifting device, and vehicle provided by the present application are provided with an adjustment assembly and a position retention assembly. The adjustment assembly comprises a force adjustment disc, a guide seat, and multiple sliding members. The force adjustment disc is used to support the three-dimensional vehicle logo. The bottom of the force adjustment disc is provided with multiple groove structures. The guide seat is assembled to the bottom of the force adjustment disc and is used to assemble multiple sliding members. The top of each sliding member extends upward relative to the guide seat and is positionally connected to the corresponding groove structure. The position retention assembly is assembled to the bottom of the sliding member and the guide seat and is connected to the clutch mechanism. The trigger force adjustment mechanism is configured to adjust the trigger force for unlocking the clutch mechanism. In addition, when an external force is applied to the three-dimensional vehicle logo, the sliding member deflects along the groove structure within the guide seat, converting the external force into a downward displacement, which is transmitted to the clutch mechanism to unlock the clutch mechanism. In this way, the three-dimensional vehicle logo can achieve the functions of position retention, displacement transmission, and trigger force adjustment, improving the adaptability of the component to different user requirements and the reliability of the component's position retention after long-term use, thus meeting the needs of different users.

[0041] The trigger force adjustment mechanism, the vehicle logo lifting device and the vehicle of the present application are described in detail below with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0042] FIG1 is a schematic structural diagram of a vehicle logo lifting device 100 according to an embodiment of the present application. FIG2 is a schematic structural diagram of the vehicle logo lifting device 100 shown in FIG1 from a side view. In combination with FIG1 and FIG2 , the vehicle logo lifting device 100 can be applied to a vehicle 200 (as shown in FIG12 ) to achieve the lifting of a vehicle logo 10. The vehicle logo 10 can be a three-dimensional vehicle logo 11 or a flat vehicle logo 12. In combination with FIG1 and FIG2 , the vehicle logo lifting device 100 includes a drive mechanism 20, a clutch mechanism 30, and a connecting rod mechanism 40. The drive mechanism 20 is provided on the vehicle body of the vehicle 200. The clutch mechanism 30 selectively connects the drive mechanism 20 and the three-dimensional vehicle logo 11. When the clutch mechanism 30 connects the drive mechanism 20 and the three-dimensional vehicle logo 11, the drive mechanism 20 can drive the three-dimensional vehicle logo 11 to move relative to the vehicle body 200 and support the three-dimensional vehicle logo 11 through the clutch mechanism 30. When the clutch mechanism 30 disconnects the drive mechanism 20 and the three-dimensional vehicle logo 11, the three-dimensional vehicle logo 11 can descend under its own weight. The clutch mechanism 30 is assembled below the three-dimensional vehicle logo 11 and selectively connects to the drive mechanism 20. Under certain conditions, the clutch mechanism 30 and the drive mechanism 20 can be connected and disconnected. When the clutch mechanism 30 is connected to the drive mechanism 20, the drive mechanism 20 drives the clutch mechanism 30, causing the three-dimensional vehicle logo 11 to move up and down relative to the vehicle body. When the clutch mechanism 30 is disconnected from the drive mechanism 20, the clutch mechanism 30 and the three-dimensional vehicle logo 11 descend under their own weight and are located within the vehicle body. The connecting rod mechanism 40 is assembled below the flat vehicle logo 12 and is located on one side of the clutch mechanism 30, abutting the clutch mechanism 30. When the clutch mechanism 30 is separated from the driving mechanism 20, the clutch mechanism 30 guides the connecting rod mechanism 40 when it descends, driving the flat logo 12 to move upward relative to the vehicle body, so that the flat logo 12 is located above the three-dimensional logo 11 and does not exceed the top surface of the vehicle body.

[0043] In the above scheme, the vehicle logo lifting device 100 is provided with a driving mechanism 20, a clutch mechanism 30 and a connecting rod mechanism 40. The three-dimensional vehicle logo 11 is assembled by the clutch mechanism 30, and the planar vehicle logo 12 is assembled by the connecting rod mechanism 40. The clutch mechanism 30 is arranged below the three-dimensional vehicle logo 11 and is selectively connected to the driving mechanism 20. When the clutch mechanism 30 is connected to the driving mechanism 20, the driving mechanism 20 drives the clutch mechanism 30, driving the three-dimensional vehicle logo 11 to move up and down relative to the vehicle body. When the clutch mechanism 30 is separated from the driving mechanism 20, the clutch mechanism 30 and the three-dimensional vehicle logo 11 descend under the action of their own gravity and are located inside the vehicle body. At the same time, when the clutch mechanism 30 descends, the connecting rod mechanism 40 is guided to drive the planar vehicle logo 12 to move upward relative to the vehicle body, so that the planar vehicle logo 12 is located above the three-dimensional vehicle logo 11 and does not exceed the top surface of the vehicle body. In this way, under normal conditions, the clutch mechanism 30 connects the three-dimensional vehicle logo 11 and the drive mechanism 20, and the vehicle logo lifting device 100 can control the three-dimensional vehicle logo 11 to rise and maintain it in a fixed position through the drive mechanism 20; when the three-dimensional vehicle logo 11 needs to be lowered normally, the drive mechanism 20 can also lower the three-dimensional vehicle logo 11 and retract it into the vehicle body through the clutch mechanism 30. When the three-dimensional vehicle logo 11 is hit by a pedestrian or moved by external force, the clutch mechanism 30 can directly disconnect the three-dimensional vehicle logo 11 from the drive mechanism 20, allowing the three-dimensional vehicle logo 11 to quickly descend under its own gravity. This descent method is faster than the descent method driven by the drive mechanism 20, effectively protecting the three-dimensional vehicle logo 11. After the three-dimensional vehicle logo 11 descends, the connecting rod mechanism 40 drives the flat vehicle logo 12 to be located above the three-dimensional vehicle logo 11. At this time, the flat vehicle logo 12 is used for display, which does not affect the recognition of the three-dimensional vehicle logo. The flat logo 12 is used to protect the three-dimensional logo 11 , and can also be used to cover the through hole in the vehicle body for penetrating the three-dimensional logo 11 , thereby making the surface of the vehicle body beautiful and improving user experience.

[0044] In this embodiment, a clutch mechanism 30 is provided between the drive mechanism 20 and the three-dimensional vehicle logo 11, and the clutch mechanism 30 can be selectively connected or disconnected. Thus, under normal conditions, the clutch mechanism 30 can connect the drive mechanism 20 and the three-dimensional vehicle logo 11 together. At this time, the drive mechanism 20 can drive the three-dimensional vehicle logo 11 to slowly rise and fall relative to the body of the vehicle 200 to ensure the normal use of the three-dimensional vehicle logo 11. In the event that the three-dimensional vehicle logo 11 is hit by a pedestrian, moved, or stolen, the clutch mechanism 30 can disconnect the drive mechanism 20 and the three-dimensional vehicle logo 11, causing the three-dimensional vehicle logo 11 to lose the support of the drive mechanism 20 and quickly descend into the vehicle body under its own gravity to avoid damage or theft.

[0045] In the embodiment shown in Figures 1 and 2, the vehicle logo lifting device 100 further includes a mounting base 50, on which the three-dimensional vehicle logo 11 is mounted, and the clutch mechanism 30 is at least partially disposed on the mounting base 50. Thus, the mounting base 50 can support and protect the three-dimensional vehicle logo 11 and at least a portion of the clutch mechanism 30, allowing the three-dimensional vehicle logo 11 to be raised and lowered together with the mounting base 50. Furthermore, when the clutch mechanism 30 disconnects the drive mechanism 20 from the three-dimensional vehicle logo 11, the three-dimensional vehicle logo 11 and at least a portion of the clutch mechanism 30 can be rapidly lowered together with the mounting base 50, thereby ensuring the stability of the vehicle logo lifting device 100.

[0046] Specifically, the mounting base 50 can be movably mounted on the vehicle body 200, and can be used to support the three-dimensional vehicle logo 11 when the three-dimensional vehicle logo 11 is raised and lowered. The driving mechanism 20 can be connected to the clutch mechanism 30, and at least a portion of the clutch mechanism 30 is directly mounted on the mounting base 50. When the driving mechanism 20 drives the clutch mechanism 30 to move, the entire mounting base 50 and the three-dimensional vehicle logo 11 on the mounting base 50 can be moved together, thereby ensuring the stability of the vehicle logo lifting device 100.

[0047] To meet the trigger force requirements of different users, the vehicle logo lifting device 100 of the present application also includes a trigger force adjustment mechanism 60, which is assembled on top of the clutch mechanism 30 and located at the bottom of the three-dimensional vehicle logo 11. This trigger force adjustment mechanism 60 can adjust the trigger force required to unlock the clutch mechanism 30. By providing this trigger force adjustment mechanism 60, the downward trigger force required to trigger the three-dimensional vehicle logo when an external force intervenes can be adjusted based on the user's actual needs and the attenuation of components (e.g., components of the clutch mechanism 30), preventing false triggering and extending the service life of components to meet user needs.

[0048] Figure 3 is a schematic diagram of the structure of a trigger force adjustment mechanism 60 according to one embodiment of the present application. Figure 4 is a schematic diagram of a portion of the structure of the trigger force adjustment mechanism 60 shown in Figure 3. Figure 5 is a schematic diagram of a portion of the structure of the trigger force adjustment mechanism 60 shown in Figure 3. Figure 6 is a schematic diagram of a portion of the structure of the trigger force adjustment mechanism 60 shown in Figure 3. Figure 7 is a schematic diagram of a portion of the structure of the trigger force adjustment mechanism 60 shown in Figure 3. Figure 8 is a schematic diagram of a portion of the structure of the trigger force adjustment mechanism 60 shown in Figure 3. Figure 9 is a schematic diagram of a portion of the structure of the trigger force adjustment mechanism 60 shown in Figure 3. Figure 10 is a schematic diagram of a portion of the structure of the trigger force adjustment mechanism 60 shown in Figure 3. Figure 11 is a schematic diagram of a portion of the structure of the trigger force adjustment mechanism 60 shown in Figure 3. With reference to Figures 1 to 11 , the trigger force adjustment mechanism 60 is assembled to a mounting base 50, which supports and secures the trigger force adjustment mechanism 60. The trigger force adjustment mechanism 60 is used to support the three-dimensional vehicle logo 11 and is assembled on top of the clutch mechanism 30. The trigger force adjustment mechanism 60 is used to adjust the trigger force for unlocking the clutch mechanism 30. When the three-dimensional car logo 11 is affected by external forces and needs to descend quickly, the trigger force adjustment mechanism 60 transmits the displacement to the clutch mechanism 30, unlocking the clutch mechanism 30 and the drive mechanism 20, thereby achieving the rapid descent of the three-dimensional car logo 11. The trigger force adjustment mechanism 60 acts as an intermediate medium to transmit the displacement generated when the three-dimensional car logo 11 is hit to the clutch mechanism 30. When the three-dimensional car logo 11 collides or someone bends the three-dimensional car logo 11, the three-dimensional car logo 11 needs to quickly descend to a safe position. Therefore, the support structure of the three-dimensional car logo 11 is required to maintain the position of the three-dimensional car logo 11 while generating a downward displacement when an external force intervenes in the three-dimensional car logo 11. The trigger force is converted into a downward displacement through the force arm conversion, triggering the clutch mechanism 30 to achieve rapid descent. The trigger force adjustment mechanism 60 can realize the functions of position maintenance, displacement transmission, and trigger force adjustment of the three-dimensional car logo 11.

[0049] In the embodiment shown in conjunction with Figures 3 to 11 , the trigger force adjustment mechanism 60 includes an adjustment assembly 601 and a position retention assembly 602. The adjustment assembly 601 includes a lever adjustment disc 603, a guide seat 604, and multiple sliding members 605. The lever adjustment disc 603 is used to support the three-dimensional vehicle logo 11. The top of the lever adjustment disc 603 is used to assemble the three-dimensional vehicle logo 11. The bottom of the lever adjustment disc 603 is provided with multiple groove structures 606 spaced circumferentially around the central axis A of the lever adjustment disc 603. The guide seat 604 is assembled to the bottom of the lever adjustment disc 603 and is used to assemble multiple sliding members 605. The top of each sliding member 605 extends upward relative to the guide seat 604 and is positionally connected to a corresponding groove structure 606. The position retention assembly 602 is assembled to the bottom of the sliding members 605 and the guide seat 604 and is connected to the clutch mechanism 30. The trigger force adjustment mechanism 60 is used to adjust the trigger force for unlocking the clutch mechanism 30. In addition, when an external force is applied to the three-dimensional vehicle logo 11 , the sliding member 605 deflects along the groove structure 606 in the guide seat 604 , converting the external force into a downward displacement, and transmitting it to the clutch mechanism 30 to unlock the clutch mechanism 30 .

[0050] In this embodiment, the central axis A of the lever arm adjustment disk 603 can be in the vertical direction. The top of the sliding member 605 protrudes from the guide seat 604 and is limited in the vertical direction by the groove structure 606. In the horizontal direction, the protruding part of the top of the sliding member 605 abuts against the groove structure 606. When an external force is applied to the three-dimensional vehicle logo 11, the sliding member 605 deflects along the groove structure 606 in the guide seat 604, converting the external force into a downward displacement and transmitting it to the clutch mechanism 30. When the external force reaches a certain value, the clutch mechanism 30 is unlocked. In this way, the functions of position maintenance, displacement transmission, and trigger force adjustment of the three-dimensional vehicle logo 11 can be realized, thereby improving the adaptability of the parts to the requirements of different users and the reliability of the parts in maintaining their position after long-term use, thereby meeting the needs of different users.

[0051] In the embodiment shown in combination with Figures 3 to 11, the adjustment component 601 can be rotated by operation and can be switched between different installation positions. The position holding component 602 is used to ensure that the clutch mechanism 30 remains connected to the drive mechanism 20 to support the three-dimensional car logo 11 when there is no external collision or force on the three-dimensional car logo 11. The lever arm adjustment plate 603 includes a base 607 and a support portion 608 movably connected to the base 607, and the support portion 608 supports the three-dimensional car logo 11. At least one installation position 609 is provided on the peripheral side of the support portion 608 (one installation position 609 is shown in the figure). The installation position 609 is used to detachably install the operating member 610. In this embodiment, the operating member 610 is detachably assembled to the side wall of the support portion 608 of the lever arm adjustment plate 603, and the operating member 610 can be rotated to different installation positions. The operating member 610 can be a locking screw, which can be fastened to the fixed axis of the three-dimensional car logo 11. When the lever arm adjustment disk 603 needs to be adjusted, the locking screw is loosened and rotated. The locking screw can lock the lever arm adjustment disk 603 in the specified position after it is adjusted to the specified position. A plurality of groove structures 606 are provided on a side of the base 607 facing the guide seat 604. When the operating member 610 is installed in one of the installation positions 609, the operating member 610 located on the support portion 608 is rotated, driving the base 607 to rotate around the central axis A of the lever arm adjustment disk 603, causing the plurality of sliding members 605 to retract from the edge of the base 607 toward the central axis A of the lever arm adjustment disk 603 within the guide seat 604, thereby adjusting the contact surface between the plurality of sliding members 605 and the position holding assembly 602 to adjust the trigger force of the unlocking clutch mechanism 30. In this embodiment, the base 607 is a disc structure, and the plurality of groove structures 606 are arranged at intervals along the circumference of the disc structure. Multiple groove structures 606 are recessed vertically from bottom to top toward one side of the support portion 608, effectively utilizing the base 607 to limit the position of the base 607 and the protruding portion of the slider 605, making the entire trigger force adjustment mechanism 60 compact and small in vertical dimensions. When the operating member 610 is switched from the first mounting position to the second mounting position, the multiple groove structures 606 rotate about the central axis A of the force arm adjustment disk 603, causing the multiple sliders 605 to retract within the guide seat 604 toward the central axis A of the force arm adjustment disk 603. This increases the contact surface between the multiple sliders 605 and the position retaining assembly 602, thereby increasing the trigger force for unlocking the clutch mechanism 30.

[0052] In this embodiment, the operation member 610 is rotated to the first installation position and the second installation position as an example for explanation. When the operation member 610 is rotated to the first installation position, which is also the initial position, the outer edge of each sliding member 605 protrudes from the outer edge of the guide seat 604. In other words, each sliding member 605 is farthest from the central axis A of the force arm adjustment plate 603 within the guide seat 604, and the contact surface between the sliding member 605 and the position holding assembly 602 is minimized. In this position, the triggering force for the three-dimensional vehicle logo 11 to drop rapidly is relatively small, and the anti-trigger function of the three-dimensional vehicle logo 11 is relatively sensitive, safe and reliable. After long-term use, the triggering force of the parts that trigger the clutch mechanism 30 will decay. Therefore, in this embodiment, when the position of the operating member 610 is adjusted, for example, by rotating the operating member 610 from the first mounting position to the second mounting position, the outer edge of each slider 605 is retracted relative to the outer edge of the guide seat 604 toward the central axis A of the lever arm adjustment disk 603. In other words, each slider 605 is slightly closer to the central axis A of the lever arm adjustment disk 603 within the guide seat 604. The two opposing sliders 605 both slide toward the central axis A of the lever arm adjustment disk 603, reducing the distance between the two opposing sliders 605. This increases the contact surface between the multiple sliders 605 and the position holding assembly 602, thereby increasing the triggering force for unlocking the clutch mechanism 30 and improving the triggering force of the components of the clutch mechanism 30. This meets the user's different triggering force requirements and solves the problem of attenuated triggering force of the components of the clutch mechanism 30. In this embodiment, the rotation direction for switching from the first mounting position to the second mounting position can be clockwise, which is compatible with the guide direction of the groove structure 606.

[0053] The trigger force adjustment mechanism 60 transmits the displacement of the three-dimensional vehicle logo 11 upon impact to the clutch mechanism 30, thereby maintaining the position of the three-dimensional vehicle logo 11, transmitting displacement, and adjusting the trigger force. By switching the operating member 610 from the first mounting position to the second mounting position, the trigger force required to trigger the three-dimensional vehicle logo 11 to descend rapidly can be adjusted to meet the trigger force requirements of different users. Furthermore, the position retention force, which weakens after long-term use, is strengthened to extend the service life of the component, thereby improving the component's adaptability to different user requirements and its reliability in maintaining position after long-term use, thus meeting the needs of different users.

[0054] In the embodiment shown in conjunction with Figures 3 to 11 , the base 607 is disc-shaped, and the groove structure 606 is an arc-shaped groove. The groove structure 606 extends from the edge of the base 607 toward the central axis A of the lever arm adjustment disk 603, and points on the groove structure 606 at the same position are located on the same circumference relative to the central axis A of the lever arm adjustment disk 603. The lever arm adjustment disk 603 is provided with a groove structure 606 with a variable radius. When the operating member 610 is operated, the lever arm adjustment disk 603 adjusts the contact surface between the slider 605 and the position retaining assembly 602, thereby changing the lever arm size and the triggering force required to trigger the 3D vehicle logo 11 to descend. With this arrangement, when the operating member 610 is rotated from the first mounting position to the second mounting position, the multiple sliders 605 can be synchronously rotated and retracted toward the central axis A of the lever arm adjustment disk 603, thereby increasing the contact surface between the multiple sliders 605 and the position retaining assembly 602, thereby increasing the triggering force required to unlock the clutch mechanism 30. This increases the triggering force for the three-dimensional vehicle logo 11 to descend rapidly downward. In this embodiment, the number of groove structures 606 is even, and the groove structures 606 are arranged in pairs. This arrangement ensures uniform guidance from the groove structures 606, evenly distributing force during adjustment, and reducing effort. The groove structures 606 are arranged symmetrically with respect to the central axis A of the lever arm adjustment plate 603. This arrangement ensures that the guidance of the groove structures 606 remains consistent, providing stable and reliable guidance.

[0055] Looking back at the embodiment shown in Figures 1 to 3, the vehicle logo lifting device 100 also includes a cover plate 70, which is fixed to the mounting base 50 by a plurality of fasteners 71. The plurality of fasteners 71 are located on the peripheral side of the trigger force adjustment mechanism 60 and are connected to the cover plate 70 and the mounting base 50, so that the trigger force adjustment mechanism 60 is housed inside, making the exterior beautiful. The mounting port of the operating member 610 (i.e., the adjustment port for adjusting the force arm adjustment disk 603 to adjust the trigger force of the unlocking clutch mechanism 30) is exposed, and the force arm can be adjusted without disassembling the surrounding parts, which is convenient for operation. The three-dimensional vehicle logo 11 is connected to the trigger force adjustment mechanism 60 and is located above the cover plate 70. The cover plate 70 is tilted to adapt to the top surface of the body of different vehicles 200, making the exterior beautiful. In this embodiment, the support portion 608 is a columnar structure having a central axis A and extending in the vertical direction. The operating member 610 is provided on the peripheral side of the support portion 608 and is located between two adjacent fasteners 71 for easy operation.

[0056] In the embodiment shown in combination with Figures 1 to 11, the guide seat 604 includes a guide groove 611 that runs through from top to bottom. The sliding member 605 includes a sliding portion 612 and a limiting portion 613 protruding from the top of the sliding portion 612. The sliding portion 612 is located in the guide groove 611, and the limiting portion 613 extends from the guide groove 611 to the outside of the guide seat 604. The limiting portion 613 is limited by the groove structure 606 on the central axis A of the force arm adjustment disk 603, and abuts against the edge of the groove structure 606 in the circumferential direction of the central axis A of the force arm adjustment disk 603. In this embodiment, the position holding component 602 plays the role of fixing the sliding portion 612. The guide groove 611 extends along the edge of the position holding component 602 in the direction of the central axis A of the force arm adjustment disk 603. When the operating member 610 rotates from the first installation position to the second installation position, the sliding portion 612 moves relatively close to the central axis A of the force arm adjustment disk 603 not only under the guidance of the groove structure 606, but also under the guidance of the guide groove 611. The direction of the movement can include two directions, one direction is along the curved direction of the groove structure 606, and the other direction is along the straight direction of the guide groove 611. In this way, the size of the trigger force for triggering the three-dimensional vehicle logo 11 to descend rapidly can be adjusted to meet the trigger force requirements of different users.

[0057] In the embodiment shown in conjunction with Figures 3 to 11 , the guide groove 611 includes a first opening 611a and a second opening 611b disposed opposite each other. The first opening 611a is disposed toward the lever arm adjustment disk 603, and the second opening 611b is disposed toward the position maintaining assembly 602. The limiting portion 613 is engaged within the first opening 611a, and the top of the sliding portion 612 abuts against the top wall of the guide groove 611. In this embodiment, the opening width of the first opening 611a is smaller than the opening width of the second opening 611b and is at least larger than the outer diameter of the limiting portion 613. This ensures that the first opening 611a serves as a guide when the limiting portion 613 slides within the guide groove 611, providing stability and reliability. Furthermore, the top of the sliding portion 612 abuts against the top wall of the guide groove 611, ensuring stability during sliding.

[0058] In the embodiment shown in combination with Figures 3 to 11, the position holding assembly 602 includes a position holding seat 614. The position holding seat 614 is used to support the adjustment assembly 601. The position holding seat 614 is assembled at the bottom of the guide seat 604, and a snap-in groove 615 is provided on the side facing the guide seat 604. The sliding portion 612 is partially located in the snap-in groove 615 and partially located in the guide groove 611. The snap-in groove 615 plays a guiding or restraining role, allowing the sliding portion 612 to slide within the track of the guide groove 611, which is more labor-saving. In this embodiment, the snap-in groove 615 is arranged corresponding to the guide groove 611. The position and number of the snap-in groove 615 are arranged in a one-to-one correspondence with the position and number of the guide groove 611. The guide groove 611 and the snap-in groove 615 are extended along the edge of the position holding assembly 602 in the direction of the central axis A of the force arm adjustment disk 603. The guide groove 611 and the engaging groove 615 extend along the edge of the base 607 toward the central axis A of the lever arm adjustment disk 603. The plurality of sliding members 605 are even in number and arranged in pairs. The plurality of sliding members 605 are arranged symmetrically about the central axis A of the lever arm adjustment disk 603. This arrangement ensures that the stopper 613 is stable and reliable when sliding within the guide groove 611.

[0059] In the embodiment shown in combination with Figures 3 to 11, the position holding seat 614 includes a transmission member 616, a support seat 617 and a flange 618. The transmission member 616 extends in the direction of the central axis A of the force arm adjustment disk 603. The transmission member 616 extends in the vertical direction. The support seat 617 and the flange 618 are assembled on the circumferential side of the transmission member 616. The support seat 617 is located at the top of the transmission member 616 and has a distance from the flange 618 in the direction of the central axis A of the force arm adjustment disk 603. The distance is adapted to the downward displacement of the three-dimensional vehicle logo 11. The position holding assembly 602 also includes an elastic member 619, which is sleeved on the transmission member 616 and is compressed between the bottom of the support seat 617 and the top of the flange 618. The elastic member 619 can be a spring. By setting a flexible position maintaining structure supported by a spring, the spring supports the gravity of the support seat 617 and the adjustment component 601, so that the three-dimensional car logo 11 is maintained in the working position. The adjustment component 601 is overlapped on the position maintaining component 602. When an external force is applied to the three-dimensional car logo 11, the external force breaks the balance and the adjustment component 601 deflects in position. When deflected, the edge of the sliding member 605 contacts the support seat 617. By adjusting the contact between the edge of the sliding member 605 and the support seat 617, the size of the trigger force is adjusted to change the force value that triggers the three-dimensional car logo 11 to descend quickly. In the above process, the support seat 617 can convert the external force into a displacement and transmit it to the clutch mechanism 30. The clutch mechanism 30 is unlocked to separate the three-dimensional car logo 11 from the drive mechanism 20. The three-dimensional car logo 11 is rapidly descended under the influence of its own gravity and the speed-descent assist spring 80, thereby realizing the speed-descent function. In this embodiment, the limiting portion 613 of the sliding member 605 can slide in the groove structure 606, and the contact radius between the sliding portion 612 of the sliding member 605 and the position holding seat 614 is changed by the force arm adjustment plate 603, thereby adjusting the force value that triggers the rapid descent of the three-dimensional vehicle logo 11. A spring support is applied to the position holding component 602, and the spring provides a flexible connection while providing a position holding function. When an external force is applied to the three-dimensional vehicle logo 11, the balance of the spring force is broken, and the position holding component 602 will be displaced. The displacement is transmitted to the clutch mechanism 30 through the transmission member 616. The structure is simple and realizes the functions of position holding and deflection displacement.

[0060] Figure 12 is a schematic diagram of a vehicle according to one embodiment of the present application. As shown in Figure 12, vehicle 200 includes a vehicle body. A vehicle logo lifting device is provided on the vehicle body. The vehicle logo lifting device 100 shown in the embodiments of Figures 1 and 2 can also be provided on the vehicle body. By providing the vehicle logo lifting device 100 shown in the embodiments of Figures 1 and 2, the three-dimensional vehicle logo 11 can be actively lowered while simultaneously guiding the flat vehicle logo 12 to rise, providing a better user experience. Alternatively, when the three-dimensional vehicle logo 11 is impacted, the flat vehicle logo 12 can be passively triggered to rise, with the vehicle 200 being displayed through the flat vehicle logo 12. The three-dimensional vehicle logo 11 is highly recognizable and has an aesthetically pleasing appearance, enhancing the user experience. In this embodiment, vehicle 200 is provided with the vehicle logo lifting device 100 having a trigger force adjustment mechanism 60 shown in the embodiments of Figures 3 to 11. This allows the downward trigger force of the three-dimensional vehicle logo 11 to be adjusted based on actual user needs and the degree of component attenuation, preventing false triggering and extending the service life of components to meet user needs.
