[0035] The present invention provides a vehicle logo lifting mechanism 100, which is fixed on the front engine cover of the vehicle and installed in the front engine compartment of the vehicle. Figures 1 to 5 As shown, the vehicle logo lifting mechanism 100 includes a guide rail 1 arranged in a vertical direction, a sliding base 2 slidable on the guide rail 1, a locking block 3, a vehicle logo assembly 4, a lifting assembly 5, a tension spring 6 and a driving assembly 8. The vehicle logo assembly 4, the lifting assembly 5 and the tension spring 6 are all arranged on the sliding base 2. The locking block 3 is locked with the lifting assembly 5, and the locking block 3 drives the sliding base 2 to slide on the guide rail 1, thereby driving the vehicle logo assembly 4 and the lifting assembly 5 to slide together. Please refer to Figure 6 As shown, a limit block 11 is also provided on the guide rail 1, and the sliding base 2 descends to the limit block 11 and stops.

[0036] Please refer to Figure 2 and Figure 7 As shown, a sliding groove 21 is provided in the sliding base 2, and the sliding groove 21 is inclined. Specifically, the sliding base 2 includes a sliding base body 22, and two spaced connecting members 23 are provided in the sliding base body 22, and the connecting member 23 is connected to the inner wall of the sliding base body 22. Two opposing protrusions 24 are provided on the connecting member 23, and the protrusions 24 and the bottom of the connecting member 23 form the sliding groove 21.

[0037] The sliding base 2 is also provided with a mounting frame 25, and a base 26 is provided at the bottom of the mounting frame 25, and the base 26 is fixed to the mounting frame 25 by bolts 27. The base 26 is engaged with the guide rail 1, so that the sliding base 2 can slide up and down on the guide rail 1. This structure can enhance the stability of the sliding base 2 on the guide rail 1. In other embodiments, the base 26 can be directly fixed to the sliding base 2, making the structure more streamlined.

[0038] Please refer to Figure 8 As shown, the locking block 3 is provided with a first sliding portion 31 and a second sliding portion 32 with an opening facing downward; the locking block 3 is provided with an inclined surface 33 and a snap-fit ​​groove 34, and the snap-fit ​​groove 34 cooperates with the lifting assembly 5. The first sliding portion 31 cooperates with the right side of the guide rail 1, so that the locking block 3 can slide on the guide rail 1. The second sliding portion 32 cooperates with the driving assembly 8, and the driving assembly 8 drives the locking block 3 to rise and fall slowly.

[0039] The engaging groove 34 and the lifting assembly 5 have a locked state and a separated state. When the engaging groove 34 and the lifting assembly 5 are locked, the locking block 3 slowly rises and falls on the guide rail 1, thereby driving the lifting assembly 5 to slowly rise and fall together. When the engaging groove 34 and the lifting assembly 5 are separated, the lifting assembly 5 quickly falls on the guide rail 1.

[0040] Please refer to Figure 2 and Fig. 9As shown, the vehicle logo assembly 4 includes a standing logo 41 and a transmission base 42 located at the bottom of the standing logo 41 . The vehicle logo assembly 4 also includes a vehicle logo base 43 , a return spring 44 and a support rod 45 disposed inside the return spring 44 .

[0041] The vertical logo 41 is loosely matched with the vehicle logo base 43, and the vehicle logo base 43 is installed on the sliding base 2 to protect the vertical logo 41. The return spring 44 is arranged between the sliding base 2 and the transmission base 42, and the return spring 44 is arranged around the support rod 45. The top end of the return spring 44 abuts against the transmission base 42, and the bottom end abuts against the sliding base 2.

[0042] The transmission base 42 converts the displacement of the vertical sign 41 in any direction into the displacement of the support rod 45 in the vertical direction. Specifically, the transmission base 42 is a plate-like structure, the top surface of the transmission base 42 abuts against the vertical sign 41, and the top of the support rod 45 abuts against the bottom surface of the transmission base 42. When the vertical sign 41 is subjected to an external force in any direction, it will be displaced, and the force will be transmitted to the transmission base 42, and a vertical downward component force will be generated on the transmission base 42, thereby causing the support rod 45 to move downward.

[0043] The bottom of the support rod 45 is connected to the lifting assembly 5. When the sign 41 is stressed, the support rod 45 moves downward, triggering the unlocking of the lifting assembly 5. During this process, the return spring 44 is compressed downward. After the car sign assembly 4 starts to descend, the return spring 44 provides an upward elastic force for the sign 41 to restore the sign 41 to the raised state.

[0044] Please refer to Figure 2 , Fig.10 and Fig.11 As shown, the lifting assembly 5 includes a transmission rack 51, a gear structure 52 and a latch 55. The transmission rack 51 is connected to the support rod 45, and the gear structure 52 is meshed with the transmission rack 51 and the latch 55 respectively. When the sign 41 is displaced by force, the transmission base 42 converts the displacement of the sign 41 into the downward displacement of the support rod 45. The support rod 45 moves downward, driving the transmission rack 51 to move downward. Then the gear structure 52 rotates counterclockwise, causing the latch 55 to slide to the side away from the locking block 3, and the latch 55 is separated from the locking block 3, and the vehicle logo assembly 4 is rapidly lowered along the guide rail 1.

[0045] Please refer to Fig.11 As shown, in this embodiment, the gear structure 52 includes a coaxially connected reversing gear 53 and an unlocking gear 54, and the reversing gear 53 and the unlocking gear 54 are connected by a rotating shaft 56, and both ends of the rotating shaft 56 are fixed on the inner wall of the sliding base 2. The reversing gear 53 is meshed with the transmission rack 51, and the unlocking gear 54 is meshed with the latch 55.

[0046] The latch 55 and the locking block 3 have two states: separated or locked. Specifically, the latch 55 cooperates with the engaging groove 34 to maintain the locked state with the locking block 3; the latch 55 can be disconnected from the locking block 3 after moving along the inclined surface 33. When the locking block 3 is locked with the latch 55, the driving component 8 drives the locking block 3 to drive the sliding base 2, the lifting component 5, and the vehicle logo component 4 to rise and fall slowly on the guide rail 1; the locking block 3 is disconnected from the latch 55, and the sliding base 2 quickly descends on the guide rail 1. Please refer to Figure 4 and Figure 5 As shown, the sliding base 2 is lowered on the guide rail 1 to a safe position.

[0047] Please refer to Fig.11 As shown, the latch 55 is divided into a clamping portion 551 and a meshing portion 552. The clamping portion 551 can move along the inclined surface 33, and the meshing portion 552 meshes with the unlocking gear 54. In a normal state, the clamping portion 551 is clamped in the clamping groove 34. When the latch 55 slides to the side away from the locking block 3, the clamping portion 551 moves upward along the inclined surface 33 and separates from the clamping groove 34.

[0048] When the transmission rack 51 moves downward, it drives the reversing gear 53 to rotate counterclockwise, and the unlocking gear 54 is driven, so that the latch 55 slides along the sliding groove 21 to the side away from the locking block 3, and then unlocks the locking block 3. By setting the number of teeth of the reversing gear 53 and the unlocking gear 54, it can be ensured that when the vertical logo 41 is subjected to a small force, the lifting assembly 5 can be unlocked, shortening the unlocking time of the vehicle logo assembly 4, and allowing the vehicle logo assembly 4 to descend quickly.

[0049] When the vehicle logo assembly 4 descends, the return spring 44 drives the transmission rack 51 to move upward, and the transmission rack 51 drives the reversing gear 53 to rotate clockwise, and the unlocking gear 54 is driven, so that the pin 55 slides along the sliding groove 21 to the side close to the locking block 3 and then returns to the initial position.

[0050] Please refer to Figures 1 to 4 As shown, the sliding base 2 is also provided with a tension spring 6, the top end of which is fixed on the sliding base 2, and the bottom end of which is fixed on the vehicle body. In another embodiment, the guide rail 1 is provided with a tension spring fixing portion, and the bottom end of the tension spring 6 is fixed on the tension spring fixing portion. When the vehicle logo assembly 4 is in a normal state, the tension spring 6 is in a stretched state; when the vehicle logo assembly 4 descends, the tension spring 6 provides a downward pulling force for the vehicle logo assembly 4, so that the vehicle logo assembly 4 descends rapidly under its own gravity and pulling force, shortening the descending time of the vehicle logo assembly 4.

[0051] Please refer to Figures 1 to 4 As shown, in this embodiment, the vehicle logo lifting mechanism 100 includes a mounting plate 7 disposed on the vehicle body, and the guide rail 1 and the locking block 3 are both disposed on the mounting plate 7. In another embodiment, the vehicle logo lifting mechanism 100 can be directly fixed on the vehicle body.

[0052] The mounting plate 7 is also provided with a slide rail 9 for the locking block 3 to slide, and the guide rail 1 and the slide rail 9 are arranged in parallel. The first slide portion 31 cooperates with the slide rail 9 to enable the locking block 3 to slide up and down. Figure 6 As shown, in this embodiment, the guide rail 1 and the slide rail 9 are integrally arranged, and the guide rail 1 is arranged higher than the slide rail 9. In another embodiment, the guide rail 1 and the slide rail 9 are arranged at different positions of the mounting plate 7, the sliding base 2 is installed on the guide rail 1, and the sliding base 2 drives the vehicle logo assembly 4 and the lifting assembly 5 to slide on the guide rail 1; the first sliding portion 31 cooperates with the slide rail 9 so that the locking block 3 can slide on the slide rail 9.

[0053] Please refer to Fig.12 As shown, the driving assembly 8 includes a motor 81, two fixed pulleys 82 and a drawstring 83. The motor 81 is connected to the two fixed pulleys 82 through the drawstring 83, and the drawstring 83 is sleeved on the outside of the two fixed pulleys 82. The two fixed pulleys 82 are arranged on the mounting plate 7 at intervals and are arranged below the guide rail 1. When the motor 81 rotates, the drawstring 83 moves to drive the fixed pulleys 82 to rotate. A second sliding portion 32 with an opening downward is provided at the bottom of the locking block 3. The second sliding portion 32 cooperates with the drawstring 83. Driven by the motor 81, the locking block 3 drives the sliding base 2 to slowly rise and fall on the guide rail 1.

[0054] The present invention also provides a vehicle, which is provided with a front engine compartment, a front engine compartment cover and a horizontal sign assembly 200. The horizontal sign assembly 200 is installed in the front engine compartment. When the sliding base 2 drives the vehicle sign assembly 4 to descend into the front engine compartment, the horizontal sign assembly 200 extends out of the front engine compartment and covers the front engine compartment cover.

[0055] After the vertical sign 41 is lowered, the vehicle identifies the position of the vertical sign 41 and controls the horizontal sign assembly 200 to extend out of the front cabin and cover the front cabin cover. When the vertical sign 41 needs to be restored to its original position, the entire vehicle identifies the position of the vertical sign 41 and controls the motor 81 to drive the locking block 3 to descend to the position of the vehicle logo assembly 4. As the locking block 3 and the latch 55 gradually approach each other, the clamping portion 551 does not move, and the inclined surface 33 contacts the clamping portion 551 until the clamping portion 551 is clamped into the clamping groove 34, and the locking block 3 stops moving. Subsequently, the motor 81 drives the locking block 3 to slide to drive the vehicle logo assembly 4 to slowly rise on the guide rail 1.

[0056] A position sensor may be provided on the vehicle to identify the position of the signpost 41. In some embodiments, the position sensor may be provided on the sliding base 2. When the signpost 41 stops descending, the position sensor transmits the position signal of the signpost 41 to the vehicle, and the vehicle controls the motor 81 to drive the locking block 3 to slowly rise along the guide rail 1, thereby driving the signpost 41 to rise outside the front hood.

[0057] In another embodiment, a pressure sensor may be provided on the limit block 11. When the vehicle logo assembly 4 descends to the limit block 11, the pressure sensor is triggered, and the pressure sensor transmits a signal to the vehicle. The vehicle controls the motor 81 to operate according to the signal from the pressure sensor, so as to drive the locking block 3 to rise slowly along the guide rail 1, thereby driving the vertical logo 41 to rise to the outside of the front hood.

[0058] The vehicle logo lifting mechanism 100 provided by the present invention has a vehicle logo assembly 4, an unlocking assembly 5 and a tension spring 6 installed on a sliding base 2, and the sliding base 2 can drive the vehicle logo assembly 4 and the unlocking assembly 5 to descend rapidly on the guide rail 1. A transmission base 42 is provided at the bottom of the vertical logo 41, and the transmission base 42 converts the displacement generated by the vertical logo 41 into a downward displacement. The transmission rack 51 moves downward to make the reversing gear 53 rotate counterclockwise, and the unlocking gear 54 rotates counterclockwise to drive the latch 55 to disconnect from the locking block 3, and the sliding base 2 as a whole descends rapidly along the guide rail 1. During the descent process, the tension spring 6 provides a downward pulling force for the sliding base 2, so that the sliding base 2 descends rapidly, shortens the unlocking stroke of the lifting assembly 5, and accelerates the descent speed of the vehicle logo assembly 4.

[0059] The overall width of the vehicle logo assembly 4 and the lifting assembly 5 is approximately the same as the width of the guide rail 1. The sliding base 2 drives the vehicle logo assembly 4 and the lifting assembly 5 to slide on the guide rail 1, so that the lateral width of the vehicle logo lifting mechanism 100 is relatively small and mainly occupies the height space of the vehicle body; the latch 55 slides to the side away from the locking block 3 to separate the lifting assembly 5 from the locking block 3. When the displacement of the latch 55 is the largest, the outer edge of the latch 55 does not exceed the outer edge of the main body 22, so that the vehicle logo lifting mechanism 100 occupies a relatively small space in the front cabin as a whole.

[0060] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any modifications, equivalent substitutions, improvements, etc. made within the content of the present application shall be included in the scope of protection of the present application.
