Description

Technical Field

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

[0002] Some car models feature a retractable 3D emblem on their hood. When raised, the emblem is exposed on the outside of the hood, and when lowered, it can be hidden on the inside of the hood. Current 3D emblem lifting mechanisms can only achieve linear raising and lowering along the vehicle's height.

[0003] However, since grille lights, front bumper mounting frames, and other components are usually placed below car logos, the current lifting mechanism for three-dimensional car logos cannot adapt to complex boundary conditions. Summary of the Invention

[0014] Optionally, the car logo lifting device further includes a locking component, which is movably mounted on the lifting rod.

[0016] Optionally, the movable arm is configured as a planar linkage mechanism, including a first link, a second link, and a third link. The first link includes a pressed end, a rotating end, and a first hinged end. The pressed end is used to be pressed by the moving block. The rotating end can rotate around a first axis. The first hinged end is hinged to the second link. The second link and the third link can rotate relative to each other around a second axis, and the second axis can rotate around a third axis. The upper end of the third link is used to install a flat car logo. The lower end of the third link is set as a second hinged end, which is located below the second axis and can rotate around a fourth axis.

[0017] Optionally, the movable arm further includes a fourth link, which is hinged to the second link and also hinged to the middle part of the third link.

[0021] Optionally, the groove includes a straight groove at the bottom and an arcuate groove at the top, the cut-off end is located at the end of the arcuate groove away from the straight groove, and the inner surface of the arcuate groove can prevent the pressed end from rotating about the first axis.

[0040] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a car logo lifting device 100 shown in an exemplary embodiment of this application.

[0041] Some car models have a three-dimensional logo, which can be raised and lowered through a logo hole on the hood. The raising and lowering of the three-dimensional logo can be achieved by a logo lifting device located under the hood.

[0042] This application provides a vehicle emblem lifting device 100, which can be raised and lowered in a curved manner to adapt to complex boundary conditions within the vehicle body. Specifically, the vehicle emblem lifting device 100 includes a lifting assembly 10 and a guiding assembly 20. The lifting assembly 10 includes a lifting rod 11, which can move along the height direction of the vehicle body (…). Figure 1 The lifting assembly 10 can rise and fall in the Z direction. The lifting assembly 10 can be driven by the drive assembly to raise and lower the lifting rod 11, which will be described in detail below.

[0043] The guide assembly 20 includes a guide rail 21 and a movable block 22 that moves along the guide rail 21 to achieve height adjustment. In the vehicle body height direction, the upper end of the guide rail 21 is higher than the lower end of the guide rail 21. The guide rail 21 is inclined or bent, one end of the guide rail 21 is fixed, and the other end is used to be positioned below the logo hole. The movable block 22 moves along the guide rail 21. Therefore, the shape of the guide rail 21 can define the movement path of the movable block 22. The inclination angle or bending degree of the guide rail 21 can be set according to the actual application scenario.

[0044] The lifting rod 11 can rise and fall under the action of driving force. The movable block 22 can follow the lifting rod 11 and rise and fall on the guide rail 21. For example, the movable block 22 can be connected to the lifting rod 11, but it is not limited to this. The three-dimensional car logo 200 can be installed on the movable block 22, and the three-dimensional car logo 200 can be raised or lowered by the raising and lowering of the movable block 22. The movable block 22 can slide or roll with the guide rail 21.

[0045] To achieve curved lifting, the lifting assembly 10 is further configured such that, as the moving block 22 moves along the guide rail 21, the lifting assembly 10 can also generate elastic deformation adapted to the movement trajectory of the moving block 22. In other words, the lifting assembly 10 can undergo elastic deformation in the same direction as the moving block 22, facilitating its movement without hindering it. The guide rail 21 can be an inclined linear guide rail or a curved arc guide rail.

[0046] As described above, by setting the inclined or curved guide rail 21, the movement trajectory of the moving block 22 can be changed accordingly to avoid other components located directly below the logo hole and prevent interference. Simultaneously, utilizing the elastic deformability of the lifting assembly 10, the lifting assembly 10 can generate elastic deformation adapted to the movement direction of the moving block 22 during the lifting and lowering process. This enables the lifting and lowering of the guide rail 21 when it is inclined or curved, adapting to the complex boundary conditions inside the vehicle body and ensuring the raising or lowering of the three-dimensional logo 200 at the logo hole.

[0047] In one embodiment, only the lifting rod 11 may be configured to undergo elastic deformation, or the entire lifting assembly 10 may be configured to undergo elastic deformation. For example, each component in the lifting assembly 10 may be made of an elastic material, including but not limited to polymeric elastic materials and metallic elastic materials. In an alternative embodiment, the lifting assembly 10 may employ a planar linkage mechanism, where each member is a metal plate, and the thickness of each metal plate is configured to allow elastic deformation under the tension of the moving block. In practical applications, the thickness of the metal plates can be selected based on the external dimensions of the lifting assembly 10. For example, when the lifting assembly 10 is small, the thickness of the metal plates needs to be relatively thin to ensure that the lifting assembly 10 can undergo elastic deformation under stress. When the lifting assembly 10 is large, the thickness of the metal plates can be relatively thick to also ensure that the lifting assembly 10 can undergo elastic deformation under stress.

[0048] Please continue to refer to this. Figure 1 In one embodiment, the lifting assembly 10 employs a planar linkage mechanism. The lifting assembly 10 further includes a first hinged rod 12 and a second hinged rod 13 that are cross-connected and hinged together. The first hinged rod 12 and the second hinged rod 13 are of equal length and are hinged at their respective midpoints. The top end of the first hinged rod 12 is movably connected to the lifting rod 11, and the top end of the second hinged rod 13 is also movably connected to the lifting rod 11. The angle between the first hinged rod 12 and the second hinged rod 13 can change under the action of a driving force. Thus, when the angle between the first hinged rod 12 and the second hinged rod 13 decreases, the lifting rod 11 can rise; when the angle between the first hinged rod 12 and the second hinged rod 13 increases, the lifting rod 11 can descend. In this design, the first hinged rod 12 and the second hinged rod 13 are hinged together to form an X-shaped crossarm, which is simple in structure and easy to implement.

[0049] Of course, the lifting component 10 is not limited to Figure 1In some other embodiments, as shown in the implementation, the lifting assembly 10 may include a plurality of connecting rods that are hinged end to end, the plurality of connecting rods being connected in a Z-shaped folding structure, and the lifting rod 11 may be connected to the topmost part.

[0050] Please refer to Figure 2 , Figure 2 for Figure 1 A simplified diagram of the lifting assembly 10 is shown in the figure.

[0051] In one embodiment, the bottom end 120 of the first hinge rod 12 can rotate around a certain axis B, with the direction of the rotation axis parallel to the direction of the hinge axis A of the first hinge rod 12 and the second hinge rod 13. The bottom end 130 of the second hinge rod 13 can reciprocate relative to the bottom end 120 of the first hinge rod 12, with the direction of movement consistent with the length direction of the lifting rod 11, thus achieving a change in the included angle between the first hinge rod 12 and the second hinge rod 13. For example, the bottom end 120 of the first hinge rod 12 can be rotatably connected to the vehicle body, and the bottom end 130 of the second hinge rod 13 can be slidably or rollwise connected to the vehicle body. In this embodiment, only one drive mechanism can be set up to drive the bottom end 120 of the first hinge rod 12 to rotate around a certain axis B. The bottom end 130 of the second hinge rod 13 can follow the rotational displacement of the first hinge rod 12, eliminating the need for other drive mechanisms and thus reducing the structural size of the lifting assembly 10.

[0052] In some other embodiments, the bottom end 120 of the first hinge rod 12 and the bottom end 130 of the second hinge rod 13 can both move in the same direction as the length direction of the lifting rod 11, thus achieving a change in the included angle between the first hinge rod 12 and the second hinge rod 13.

[0053] exist Figure 2 In the illustrated embodiment, the top end 121 of the first hinge rod 12 can rotate relative to the lifting rod 11 and can move relative to the lifting rod 11 along the length direction of the lifting rod 11. In this way, the degree of freedom of the first hinge rod 12 can be increased, and the flexibility of the lifting assembly 10 can be improved.

[0054] For reference, the top end 131 of the second hinge rod 13 can also rotate relative to the lifting rod 11, and can move relative to the lifting rod 11 along the length direction of the lifting rod 11. In this way, the degree of freedom of the second hinge rod 13 can be increased, further improving the flexibility of the lifting assembly 10.

[0055] In one specific embodiment, the top end 121 of the first hinge rod 12 can be slidably hinged to the lifting rod 11. In another alternative embodiment, the top end of the first hinge rod 12 is provided with a rotatable shaft, which is slidably connected to the lifting rod 11 along its length. The connection method between the top end 131 of the second hinge rod 13 and the lifting rod 11 can refer to the above configuration and will not be repeated here.

[0056] Please combine Figure 1 and Figure 2 In one embodiment, the motor 14 and transmission assembly 15 can output driving force to the lifting assembly 10, causing the lifting rod 11 to rise and fall. Specifically, the output shaft of the motor 14 is equipped with a gear, and the motor 14 is fixedly connected to the bracket 16. The transmission assembly 15 has a sector-shaped toothed portion, which is rotatably connected to the bracket 16. The gear meshes with the sector-shaped toothed portion, and the first hinge rod 12 is fixedly connected to the axis of the sector-shaped toothed portion. When the output shaft of the motor 14 rotates, the gear drives the sector-shaped toothed portion to rotate relative to the bracket 16, and simultaneously drives the first hinge rod 12 to rotate, thereby changing the angle between the first hinge rod 12 and the second hinge rod 13. By setting the transmission assembly 15, speed reduction and torque increase can be achieved. It should also be noted that the transmission assembly 15 includes, but is not limited to, [specific features not included in the original text]. Figure 1 The fan-shaped toothed portion is shown in the figure.

[0057] The car logo lifting device 100 provided in this application also has a car logo quick-down function. When the three-dimensional car logo 200 exposed on the front hood collides with a pedestrian or someone pries the three-dimensional car logo 200, the three-dimensional car logo 200 can be quickly lowered. On the one hand, it can prevent pedestrians from being injured, and on the other hand, it can prevent the three-dimensional car logo 200 from being stolen or lost.

[0058] Please refer to Figure 3 , Figure 3 for Figure 1 The diagram shows a partial structure of the car logo lifting device 100, in which part of the lifting assembly 10 has been removed.

[0059] In one embodiment, the car emblem lifting device 100 further includes a locking member 30, a pressing component 40, and an elastic member 50. The locking member 30 is movable and has a locked position and an unlocked position. The three-dimensional car emblem 200 can be installed on top of the pressing component 40. When the three-dimensional car emblem 200 is not subjected to external force, the locking member 30 is in the locked position, and the locking member 30 cooperates with the moving block 22 to lock, and the two remain relatively fixed. At this time, the locking member 30 and the moving block 22 move up and down synchronously with the lifting rod 11 to realize the normal lifting and lowering of the three-dimensional car emblem 200. When the three-dimensional car emblem 200 is subjected to external force, the external force is transmitted to the pressing component 40, and the locking member 30 can be pressed by the pressing component 40, so that the locking member 30 and the moving block 22 are unlocked, the locking member 30 changes to the unlocked position, so that the locking member 30 and the moving block 22 are separated from each other, and the moving block 22 and the three-dimensional car emblem 200 can descend together under the action of gravity. Figure 3 In the embodiment shown, when the three-dimensional car logo 200 is pressed or pried, the external force can cause the pressing component 40 to press the locking member 30, thereby causing the locking member 30 to switch to the unlocked position.

[0060] Furthermore, in order to enable the three-dimensional car logo 200 to descend more quickly, in one embodiment, the elastic force of the elastic element 50 can be used to apply a force to the moving block 22 in the same direction as gravity. The resultant force of gravity and elastic force can make the moving block 22 descend rapidly in a state of supergravity acceleration, thereby achieving the rapid descent of the three-dimensional car logo 200.

[0061] In one embodiment, the pressure-sensitive component 40 is movably disposed on the movable block 22, and the elastic element 50 is compressible and deformable along the direction of gravity. When the locking member 30 is locked to the movable block 22, the elastic element 50 is in a compressed state and compressed between the pressure-sensitive component 40 and the movable block 22, at which time the elastic element 50 stores energy. When the locking member 30 separates from the movable block 22, the elastic element 50 responds quickly and releases energy. At this time, the elastic element 50 can apply an elastic force to the movable block 22 in the same direction as gravity. Thus, when the locking member 30 separates from the movable block 22, the elastic element 50 drives the movable block 22 to descend through elastic restoring force. The movable block 22, under the combined action of gravity and elastic force, descends rapidly along with the pressure-sensitive component 40 and the three-dimensional car emblem 200. The elastic element 50 can be a compression spring, but is not limited to this.

[0062] Please combine Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of a movable block 22 shown in an exemplary embodiment of this application.

[0063] The movable block 22 includes a plate-shaped portion 220 extending horizontally from the top in a direction perpendicular to the lifting rod 11. The plate-shaped portion 220 has a through hole 2200. The pressing component 40 passes through the through hole 2200 and is movable along the axial direction of the through hole 2200. The pressing component 40 includes a mounting base 41 and a pressing rod 42 connected to each other. The mounting base 41 is located above the plate-shaped portion 220 and is used to connect with the three-dimensional car logo 200. The pressing rod 42 is located below the plate-shaped portion 220 and is used to press the locking member 30. The upper end of the elastic member 50 abuts against the mounting base 41, and the lower end of the elastic member 50 abuts against the plate-shaped portion 220. With this configuration, the pressure-sensitive component 40 can move relative to the moving block 22 along the axial direction of the through hole 2200. This limits the direction of movement of the pressure-sensitive component 40, ensuring that the pressure can be reliably transmitted to the pressure-sensitive component 40 when the three-dimensional car logo 200 is pressed. This, in turn, ensures that the pressure-sensitive component 40 can reliably press against the locking member 30, thereby improving the sensitivity of the action of the pressure-sensitive component 40.

[0064] It should be noted that the diameter of the through hole 2200 can be set to be larger, so that when the three-dimensional car logo 200 is pried open, the touch component 40 has a larger range of motion, thereby enabling the touch component 40 to generate a larger stroke and ensuring that the touch component 40 can press against the locking component 30.

[0065] Please combine Figure 3 and Figure 5 , Figure 5 This is a schematic diagram of the structure of the car logo lifting device 100.

[0066] In one embodiment, the mounting base 41 has a stepped structure, including a mounting portion 410 at the top and a shaft portion 411 at the bottom. The mounting portion 410 is the larger end, and the shaft portion 411 is the smaller end. The mounting portion 410 is used to connect with the three-dimensional car emblem 200. The bottom surface area of ​​the mounting portion 410 is larger than the opening area of ​​the through hole 2200. The shaft portion 411 passes through the through hole 2200 and is clearance-fitted with the through hole 2200. This prevents the mounting base 41 from falling out of the through hole 2200 and allows it to move up and down within the through hole 2200. The elastic element 50 is disposed within the through hole 2200 and sleeved on the outside of the shaft portion 411. This ensures the stability of the elastic element 50 during expansion and contraction and reliably applies the elastic restoring force to the moving block 22.

[0067] To facilitate the abutment of the elastic member 50 against the plate-shaped portion 220, a stepped surface can be provided on the inner surface of the through hole 2200, and the lower end of the elastic member 50 abuts against the stepped surface.

[0068] In one embodiment, the plate-shaped portion 220 further includes an annular flange 2202 surrounding the through hole 2200. The annular flange 2202 protrudes axially along the through hole 211, and the hollow portion of the annular flange 2202 communicates with the through hole 2200. When the thickness of the plate-shaped portion 220 is small, a stepped surface can be provided on the inner surface of the annular flange, which increases the convenience of setting the stepped surface. Additionally, the annular flange 2202 can also provide guidance for the vertical movement of the shaft portion 411 relative to the plate-shaped portion 220.

[0069] Please continue to refer to this. Figure 3 In one embodiment, the pressing rod 42 is movably disposed relative to the mounting base 41. The pressing rod 42 has a pressing position and a non-pressing position. In the pressing position, the pressing rod 42 can press the locking member 30 to separate it from the moving block 22. In the non-pressing position, the pressing rod 42 does not press the locking member 30, and the locking member 30 is not subjected to force. Furthermore, the pressing rod 42 can move to the pressing position when the mounting base 41 moves downward. This arrangement increases the degree of freedom of movement of the pressing rod 42. When the mounting base 41 moves downward, it can drive the pressing rod 42 to move relative to the mounting base 41, thereby allowing the pressing rod 42 to press against the locking member 30. Moreover, by movably disposing of the pressing rod 42, the direction of power transmission can be changed according to the spatial layout, which is beneficial for optimizing the structural layout. This application does not limit the movement mode of the pressing rod 42, including but not limited to movement or rotation.

[0070] Of course, in some other embodiments, the pressing rod 42 can be kept relatively fixed to the mounting base 41, and the pressing rod 42 can press against the locking member 30 as it moves down with the mounting base 41. In this embodiment, a pressing ramp can be provided on the locking member 30, and the locking member 30 can be unlocked by sliding the pressing rod 42 on the pressing ramp.

[0071] exist Figure 3 and Figure 5 In the illustrated embodiment, the pressing lever 42 is used to press the locking member 30 via a lever principle. Specifically, one end of the pressing lever 42 is rotatably connected to the shaft 411, and the other end of the pressing lever 42 is a free end 420, which is used to contact the locking member 30. The pressing lever 42 is also rotatably connected to the moving block 22 at its middle section. The pivot A1 at the rotatable connection between the pressing lever 42 and the shaft 411 is parallel to the pivot A2 at the rotatable connection between the pressing lever 42 and the plate-shaped part 220. With this configuration, the pressing lever 42 rotates on a fixed axis, resulting in a small rotation space and a compact structure. The pivots A1 and A2 can be parallel to the hinge axis A of the lifting assembly 10 when it is not deformed.

[0072] To ensure that the pressing lever 42 reliably presses against the locking member 30, the surface 310 of the locking member 30 pressed by the free end 420 is set as an inclined surface. Along the sliding direction when the free end 420 presses against the locking member 30, this surface 310 gradually slopes towards the side closer to the pressing lever 42. In this way, as the free end 420 rotates continuously, the locking member 30 can move continuously, and the stroke of the movement gradually increases, ensuring that the locking member 30 moves to the unlocked position and increasing the reliability of the contact.

[0073] This application does not limit the manner in which the locking member 30 is movably connected to the lifting rod 11. The movement of the locking member 30 includes, but is not limited to, moving or rotating. In this embodiment, the locking member 30 is rotatably configured, with the axis of rotation parallel to the axis of rotation at the rotatable connection between the pressing rod 42 and the shaft portion 411. Specifically, the locking member 30 is rotatably connected to the lifting rod 11. The lifting rod 11 has an extension rod 110 extending perpendicular to its own length. The locking member 30 is rotatably connected to the end of the extension rod 110 away from the lifting rod 11. Furthermore, the axis of rotation A3 of the locking member 30 (refer to...) Figure 5 The rotating shaft A1 is parallel to the rotatable connection between the pressure rod 42 and the shaft 411.

[0074] In one embodiment, multiple locking members 30 can be provided and symmetrically arranged on two opposite sides of the plate-shaped portion 220, working together with the plate-shaped portion 220 to lock and unlock, thus ensuring the stability and balance of the force on the plate-shaped portion 220 when locked. Correspondingly, multiple pressing rods 42 can also be provided, each corresponding to one of the locking members 30. Each pressing rod 42 can drive its corresponding locking member 30 to move synchronously, realizing the synchronous unlocking of multiple locking members 30. In this embodiment, two locking members 30 and two pressing rods 42 are provided.

[0075] In one embodiment, such as Figure 5 As shown, the locking member 30 has a slot 32 on the side facing the plate-shaped portion 220, and the edge of the plate-shaped portion 220 engages with the slot 32. When the edge of the plate-shaped portion 220 is engaged in the slot 32, the moving block 22 is locked to the lifting rod 11. When the edge of the plate-shaped portion 220 disengages from the slot 31, the moving block 22 is released from the locking of the lifting rod 11.

[0076] After the three-dimensional car logo 200 is rapidly lowered, the vehicle's recognition module can identify the three-dimensional car logo 200 and generate a corresponding electrical signal. The drive motor 14 is controlled by this electrical signal and can output driving force to make the three-dimensional car logo 200 rise again.

[0077] Please combine Figure 1 and Figure 6 , Figure 6 for Figure 1 Another schematic diagram of the car logo lifting device 100 shown in the figure.

[0078] Some models can also have a flat logo 300, which can be used to cover the logo hole on the hood. In other words, when the three-dimensional logo 200 is lowered, the flat logo 300 can be used to cover the logo hole, thereby improving the vehicle's appearance.

[0079] In one embodiment, the car emblem lifting device 100 further includes a movable arm 60 for delivering the flat car emblem 300 to the emblem opening on the hood. The movable arm 60 is driven by the movable block 22 as the three-dimensional car emblem 200 is lowered, causing the flat car emblem 300 to cover the opening. This configuration allows the movable arm 60 to be driven as the three-dimensional car emblem 200 is lowered, enabling the movable arm 60 to move the flat car emblem 300 quickly and shortening the replacement time of the flat car emblem 300. Furthermore, by covering the emblem opening with the flat car emblem 300, the three-dimensional car emblem 200 can also be hidden inside the hood. Figure 1 This is a schematic diagram of the 200-degree raised 3D car logo. Figure 6 This is a schematic diagram showing the 3D car logo 200 lowered and the flat car logo 300 located at the hole.

[0080] Please refer to Figures 7 to 9 , Figure 7 and Figure 8 This is a schematic diagram of part of the structure of the car logo lifting device 100. Figure 9 This is a schematic diagram of the third link 63.

[0081] This application does not limit the specific implementation of the movable arm 60. In this embodiment, the movable arm 60 is configured as a planar linkage mechanism, which has a simple structure and is easy to implement. Specifically, the movable arm 60 includes a first link 61, a second link 62, and a third link 63. The first link 61 includes a pressed end 610, a rotating end 611, and a first hinged end 612. The pressed end 610 is used to be pressed by the moving block 22, the rotating end 611 can rotate around the first axis O1, and the first hinged end 612 is hinged to the second link 62. The rotating end 611 can be rotatably connected to the vehicle body, and the axis of rotation is the first axis O1.

[0082] The second link 62 can rotate relative to the third link 63, and can also rotate relative to each other around the same second axis O2, which can also rotate around the third axis O3. The third link 63 can rotate around the second axis O2 at its middle position.

[0083] The upper end of the third link 63 is used to mount the flat car emblem 300, and the lower end of the third link 63 is the second hinge end 630, which can rotate around the fourth axis O4. The second hinge end 630 is located below the second axis O2. In this design, power is sequentially transmitted from the first link 61 to the second link 62 and the third link 63. Since the first hinge end 612 rotates around the first axis O1, the second hinge end 630 rotates around the fourth axis O4, and the second axis O2 rotates around the third axis O3, the movement trajectories of the first hinge end 612, the second hinge end 630, and the second axis O2 are restricted. Therefore, the trajectory requirement for delivering the flat car emblem 300 to the emblem hole is achieved, and the positional accuracy of the flat car emblem 300 when moved by the third link 63 is also improved.

[0084] In one embodiment, the movement trajectory of the second axis O2 can be restricted by setting a first arc-shaped groove. For example, the first arc-shaped groove with the axis of the third axis O3 as the center and the radius of the first arc-shaped groove as the preset value slides with the second axis O2, thereby restricting the movement trajectory of the second axis O2. The first arc-shaped groove can be set on the vehicle body.

[0085] In this embodiment, the movable arm 60 further includes a fourth link 64, which is hinged to the second link 62 and also hinged to the middle portion of the third link 63. The hinge axis between the fourth link 64 and the second link 62, and between the fourth link 64 and the third link 63, are both the second axis O2. The fourth link 64 can also rotate around the third axis O3. With this configuration, one end of the fourth link 64 can rotate around the third axis O3, while the other end is coaxially hinged to the second link 62 and the third link 63, allowing the second link 62 and the third link 63 to rotate relative to each other around the second axis O2. Furthermore, the movement trajectory of the second axis O2 is restricted by the third axis O3. Compared to using a first arc-shaped slide groove, the structure is relatively simple and compact.

[0086] This application does not limit the specific structure of the fourth link 64. In this example, the fourth link 64 includes two spaced-apart and parallel-extending sub-links 640, and a third link 63 is hinged to the two sub-links 640 at the middle position via a hinge axis. One of the two sub-links 640 is also hinged to a second link 62. The hinge axis between the third link 63 and the two sub-links 640, and the hinge axis between the second link 62 and one of the sub-links 640, are both the second axis O2. The fourth link 64 can be rotatably connected to the vehicle body, with the rotation axis being the third axis O3.

[0087] The specific shape of the third link 63 can be set according to the actual scenario, as long as it can drive the flat car logo 300 to the hole. In this embodiment, the third link 63 is set as a rod with a bend in the middle, and the third link 63 is hinged to the fourth link 64 at the bend, but it is not limited to this.

[0088] In one embodiment, the movement trajectory of the second hinge end 630 can also be limited by providing a second arc-shaped groove. For example, a second arc-shaped groove with a radius of a preset value centered on the axis of the fourth shaft O4 slides with the second hinge end 630, thereby limiting the movement trajectory of the second hinge end 630. The second arc-shaped groove can be provided on the vehicle body.

[0089] In this embodiment, the movable arm 60 further includes a fifth link 65, one end of which is hinged to the second hinge end 630, and the other end of which can rotate around the fourth axis O4. This configuration allows the second hinge end 630 to rotate around the fourth axis O4, thus limiting the movement trajectory of the second hinge end 630. Compared to using a second arc-shaped slide groove, the structure is relatively simple and compact.

[0090] The fifth link 65 can be set as an arc-shaped link. One end of the fifth link 65 is hinged to the second hinge end 630, and the other end can be rotatably connected to the vehicle body. The pivot is the fourth axis O4.

[0091] Please refer to Figure 8 The movable block 22 is provided with a sliding groove 221, and the pressed end 610 slides in conjunction with the sliding groove 221. The top end of the sliding groove 221 is a stop end 2210, which can press the pressed end 610 when the movable block 22 moves downward. That is, the pressed end 610 can slide within the sliding groove 221 and can also be pressed by the stop end 2210, thereby restricting the movement trajectory of the pressed end 610 and improving the displacement accuracy of the pressed end 610.

[0092] Please refer to Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of part of the structure of the car logo lifting device 100 when the flat car logo 300 is located at the car logo hole. Figure 11 This is a schematic diagram of the movable block 22.

[0093] In one embodiment, the pressed end 610 is located at the cut-off end 2210 when the flat car logo 300 is located at the hole. In the direction in which the external force applied to the flat car logo 300 drives the pressed end 610 to rotate around the first axis O1, the cut-off end 2210 and the pressed end 610 are mutually limiting and engaged, so that the movable arm 60 is in a dead position. With this configuration, when the flat car logo 300 is pressed by an external force, the movable arm 60 will not move, and the flat car logo 300 can always remain and cover the car logo hole.

[0094] like Figure 11 As shown, the slide groove 221 includes a straight groove 2211 at the bottom and an arc-shaped groove 2212 at the top. The cut-off end 2210 is located at the end of the arc-shaped groove 2212 away from the straight groove 2211. The inner surface of the arc-shaped groove 2212 engages with and limits the movement of the pressed end 610 when it rotates around the first axis O1, thus restricting the movement of the pressed end 610. In this design, by setting the top of the slide groove 221 as an arc-shaped groove 2212 to limit the pressed end 610, the structure is relatively simple.

[0095] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
