[0001] This invention relates to the field of vehicle technology, and in particular to a method, device, vehicle, and storage medium for controlling vehicle logos. Background Technology
[0002] With the development of technology, people have increasingly higher demands for the sophistication and technological feel of vehicles. Vehicles feature logos, which are among the most important components, enhancing brand recognition and reflecting the vehicle's refinement and technological sophistication.
[0003] In related technologies, the car logo can move between a retracted position and a displayed position. The car logo moves at a constant speed when rising or falling, which can easily cause jamming during the start-up and stopping phases, causing the car logo to vibrate and making it unable to run smoothly, thus reducing the reliability of the car logo. Summary of the Invention
[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the object of the present invention is to provide a method, apparatus, vehicle, and storage medium for controlling vehicle logos.
[0005] The present invention proposes a control method for a vehicle logo, wherein the vehicle logo is configured to rise or fall along a running track under the drive of a motor. The method includes the following steps: controlling the vehicle logo to run in response to a vehicle logo running control command; acquiring the running information of the vehicle logo during the running of the vehicle logo; and controlling the running speed of the vehicle logo based on the running information of the vehicle logo.

[0010] Furthermore, based on the vehicle logo's running information, the vehicle logo is controlled to have different running speeds at different parts of the running track, including: when the vehicle logo rises, the running speed of the vehicle logo is controlled to gradually increase from zero until the vehicle logo reaches a preset distance from the other end of the first track or the running time of the vehicle logo reaches a first preset time, then the vehicle logo is controlled to run at a preset target speed until the vehicle logo reaches a preset distance from the other end of the second track or the running time of the vehicle logo reaches a second preset time, then the running speed of the vehicle logo is controlled to gradually decrease from the target speed until the running speed corresponding to the vehicle logo reaching the other end of the second track or the running time of the vehicle logo reaches a third preset time is zero.
[0011] Furthermore, based on the vehicle logo's running information, the vehicle logo is controlled to have different running speeds at different parts of the running track, including: when the vehicle logo descends, the running speed of the vehicle logo is controlled to gradually increase from zero until the vehicle logo reaches a preset distance from the other end of the second track or the running time of the vehicle logo reaches a fourth preset time, then the vehicle logo is controlled to run at a preset target speed until the vehicle logo reaches a preset distance from the other end of the first track or the running time of the vehicle logo reaches a fifth preset time, then the running speed of the vehicle logo is controlled to gradually decrease from the target speed until the running speed corresponding to the vehicle logo reaching the other end of the first track or the running time of the vehicle logo reaches a sixth preset time is zero.
[0012] Furthermore, the first track is constructed as a circular arc track, and the second track is constructed as a straight track.
[0013] Furthermore, the running speed of the car logo is controlled by controlling the rotational speed of the motor.
[0014] Furthermore, the speed of the motor is controlled by controlling the duty cycle of the voltage driving the motor.
[0015] Furthermore, the motor is configured as a dual Hall effect motor.
[0016] According to the vehicle logo control method of the present invention, during the operation of the vehicle logo, by acquiring the operation information of the vehicle logo and controlling the operation speed of the vehicle logo according to the operation information, vibration of the vehicle logo during the rising or falling process can be avoided, thereby ensuring that the vehicle logo reaches the target position smoothly and improving the reliability of the vehicle logo.

[0041] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.
[0042] The following is for reference. Figures 1-8 A method, apparatus, vehicle, and storage medium for controlling vehicle logos according to embodiments of the present invention are described.
[0043] First, combined Figure 1-6 This invention describes a vehicle logo and its related driving structure according to embodiments of the present invention. A vehicle logo device 100 according to an embodiment of the present invention may mainly include: a base plate 10, a logo lifting assembly 20, a logo assembly 30, and a running track 40. The logo lifting assembly 20 is movably disposed on the base plate 10 and has a sliding portion 21. The logo assembly 30 is in a driving cooperation with the logo lifting assembly 20. The running track 40 is disposed on the base plate 10 and cooperates with the sliding portion 21.
[0044] Specifically, the logo lifting assembly 20 is movably mounted on the base plate 10, and the logo assembly 30 is driven by the logo lifting assembly 20. Thus, the logo lifting assembly 20 can drive the logo assembly 30 to move relative to the base plate 10, thereby achieving the movement of the logo assembly 30 relative to the base plate 10. Furthermore, a sliding part 21 is provided on the logo lifting assembly 20, and a running track 40 is provided on the base plate 10. The running track 40 can cooperate with the sliding part 21 to limit the sliding path of the logo lifting assembly 20 relative to the base plate 10, thereby limiting the movement path of the logo assembly 30 relative to the base plate 10, making the movement of the logo assembly 30 relative to the base plate 10 more stable and reliable.
[0045] Combination Figures 1-6 As shown, the running track 40 mainly includes: a first track 41, a trajectory change segment 42, and a second track 43. In the top-down direction, the trajectory change segment 42 connects the first track 41 and the second track 43. The first track 41 is an arc segment, and the trajectory change segment 42 is bent relative to the first track 41. The trajectory change segment 42 includes at least two sequentially connected arc segments with different centers. The second track 43 is a straight segment. Specifically, in the top-down direction, the first track 41, the trajectory change segment 42, and the second track 43 are connected sequentially to form the overall structure of the running track 40. The sliding part 21 can sequentially pass through the first track 41, the trajectory change segment 42, and the second track 43, thereby driving the logo assembly 30 to move relative to the base plate 10.
[0046] Furthermore, by setting the first track 41 as an arc segment, bending the trajectory change segment 42 relative to the first track 41, and the trajectory change segment 42 mainly comprising two sequentially connected arc segments with different centers, and setting the second track 43 as a straight segment, this not only ensures the smooth connection of the first track 41, the trajectory change segment 42, and the second track 43, but also optimizes the structural design of the running track 40, allowing the sliding part 21 to slide smoothly along the running track 40, thereby making the movement of the car logo component 30 relative to the base plate 10 more stable and smooth. Moreover, when the sliding part 21 slides to the trajectory change segment 42, the car logo lifting component 20 can drive the car logo component 30 to tilt in accordance with the shape of the trajectory change segment 42, thereby reducing the space occupied by the car logo component 30 when it is retracted into the car logo device 100 of the vehicle, and improving the structural compactness of the car logo device 100.
[0047] Furthermore, the sliding part 21 is slidably disposed within the second slide groove 12. When the sliding part 21 switches between groove segments, the other end of the driven link 322 changes its movement state within the first slide groove 11. The extension directions of the multiple groove segments of the second slide groove 12 are set differently, and one end of the driven link 322 is connected to the logo assembly 30, while the other end of the driven link 322 is slidably disposed within the first slide groove 11. Thus, under the premise that the active link assembly 321 drives the logo assembly 30 to move up and down relative to the base plate 10... When the sliding part 21 switches the slot, the movement direction of the sliding part 21 changes, and the other end of the driven link 322 changes the movement state in the first slide groove 11 accordingly. This allows the other end of the driven link 322 to selectively rotate around a fixed point to maintain the upright or flipped state of the logo assembly 30, or to slide along the first slide groove 11 to flip the logo assembly 30 relative to the substrate 10, thereby tilting or straightening the logo assembly 30. This makes the movement of the logo assembly 30 relative to the substrate 10 simpler and more reliable.
[0048] Therefore, by setting the trajectory change segment 42 as at least two sequentially connected arc segments with different centers, not only can the car logo component 30 tilt on the trajectory change segment 42, but the movement of the car logo component 30 can also be made more stable and smooth, thus optimizing the structural design of the vehicle logo device 100.
[0049] Combination Figure 1As shown, the trajectory change segment 42 can mainly include: a first sub-slide rail segment 421 and a second sub-slide rail segment 422. The first sub-slide rail segment 421 is connected between the first track 41 and the second sub-slide rail segment 422. The center of the circle corresponding to the first sub-slide rail segment 421 and the center of the circle corresponding to the first track 41 are both located on one side of the running track 40, and the center of the circle corresponding to the second sub-slide rail segment 422 is located on the other side of the running track 40. Specifically, the first sub-slide rail segment 421 is connected between the first track 41 and the second sub-slide rail segment 422. By setting the center of the first sub-slide rail segment 421 and the center of the first track 41 together on one side of the running track 40, and placing the center of the second sub-slide rail segment 422 on the other side of the running track 40, while ensuring that the car logo component 30 can tilt through the trajectory change segment 42, not only can the connection between the first track 41 and the first sub-slide rail segment 421, the first sub-slide rail segment 421 and the second sub-slide rail segment 422, and the second sub-slide rail segment 422 and the second track 43 be smoother, thus making the sliding part 21 slide more stably and smoothly in the running track 40, but also can reduce the space occupied by the second track 43, thereby further improving the structural compactness of the vehicle logo device 100.
[0050] Furthermore, combined Figure 1 As shown, the circumferential radius corresponding to the first track 41 is R1, the circumferential radius corresponding to the first sub-slide section 421 is R2, and the circumferential radius corresponding to the second sub-slide section 422 is R3. R1, R2, and R3 satisfy the relationship: R1 > R3 > R2. Specifically, the circumferential radius corresponding to the first track 41 is set to be larger than the circumferential radius corresponding to the second sub-slide section 422, and the circumferential radius corresponding to the second sub-slide section 422 is set to be larger than the circumferential radius corresponding to the first sub-slide section 421. This not only ensures smooth connection between the first track 41, the trajectory change section 42, and the second track 43, making the movement of the vehicle logo component 30 relative to the base plate 10 more stable and smooth, but also reduces the space occupied by the running track 40, further improving the structural compactness of the vehicle logo device 100.
[0051] Furthermore, combined Figure 1 as well as Figures 3-6As shown, R1, R2 and R3 satisfy the following relationships: 200mm≤R1≤250mm, 10mm≤R2≤20mm, 30mm≤R3≤40mm. Furthermore, by setting the circumference of the first track 41, the circumference of the first sub-slide section 421, and the circumference of the second sub-slide section 422 within reasonable ranges, the following advantages are achieved: Firstly, the curvature of the first track 41 can be larger, ensuring that the car emblem component 30 retracts vertically into the vehicle emblem device 100 as the sliding part 21 slides along the first track 41. This reduces the opening area of the car emblem component 30, preventing the internal structure from being exposed after the car emblem component 30 is raised, thus improving the reliability and sophistication of the vehicle emblem device 100. Secondly, the curvature of the first sub-slide section 421 and the second sub-slide section 422 can be smaller, with the curvature of the first sub-slide section 421 being smaller than that of the second sub-slide section 422. This allows for a more reasonable tilt angle of the car emblem component 30 when the sliding part 21 slides along the trajectory change section 42, thereby further optimizing the structural design of the running track 40 and improving the structural compactness and reliability of the vehicle emblem device 100.
[0052] Combination Figures 1-6 As shown, the arc length of the first track 41 is L1, the arc length of the first sub-slide segment 421 is L2, and the arc length of the second sub-slide segment 422 is L3. L1, L2, and L3 satisfy the relationship: L1 > L3 > L2. Specifically, the arc length of the first track 41 is set to be greater than the arc length of the first sub-slide rail segment 421, and the arc length of the first sub-slide rail segment 421 is set to be greater than the arc length of the second sub-slide rail segment 422. This allows the arc length of the first track 41 to be larger, so that when the sliding part 21 slides along the first track 41, the sliding part 21 can drive the car emblem component 30 to descend a sufficient distance, ensuring that the car emblem component 30 can be completely retracted into the vehicle's emblem device 100. On the other hand, it allows the arc lengths of both the second sub-slide rail segment 422 and the first sub-slide rail segment 421 to be smaller, and the arc length of the second sub-slide rail segment 422 is greater than the arc length of the first sub-slide rail segment 421. This allows the tilting angle of the car emblem component 30 to be more reasonable, preventing the tilted car emblem component 30 from occupying too much space. This further optimizes the structural design of the running track 40 and improves the structural compactness and reliability of the vehicle's emblem device 100.
[0053] Combination Figures 1-6As shown, the vehicle emblem device 100 may further include an emblem covering component 50. The emblem covering component 50 is disposed on the side of the running track 40 away from the emblem lifting component 20. After the sliding part 21 slides to the second sub-slide rail section 422, the emblem covering component 50 contacts the emblem component 30 and moves synchronously. Specifically, by disposing of the emblem covering component 50 on the side of the running track 40 away from the emblem lifting component 20, when the sliding part 21 slides to the second sub-slide rail section 422, the inclined emblem component 30 can contact the emblem covering component 50. As the sliding part 21 further slides on the second sub-slide rail section 422, the emblem component 30 can apply a force to the emblem covering component 50, thereby achieving synchronous movement of the emblem covering component 50 and the emblem component 30. This allows the emblem covering component 50 to cover the corresponding opening of the emblem component 30 in a timely manner, preventing the opening from being exposed for a long time and improving the reliability of the vehicle emblem device 100.
[0054] Furthermore, combined Figures 1-6 As shown, the logo covering assembly 50 may mainly include: a first rotating member 51, a second rotating member 52, and a logo cover plate 53. The first rotating member 51 and the second rotating member 52 are both rotatably disposed on the base plate 10. The second rotating member 52 is disposed above the first rotating member 51. The logo lifting assembly 20 is in transmission cooperation with the first rotating member 51 during the retraction process. The second rotating member 52 is in sliding cooperation with the first rotating member 51. The logo cover plate 53 is disposed on the second rotating member 52. Specifically, the first rotating member 51 and the second rotating member 52 are rotatably disposed on the base plate 10, and the second rotating member 52 is disposed above the first rotating member 51. The logo cover plate 53 is disposed on the second rotating member 52. In this way, the logo assembly 30 tilts during the retraction process, and the logo assembly 30 can be driven to cooperate with the first rotating member 51, so that the first rotating member 51 rotates clockwise relative to the base plate 10. Furthermore, through the sliding cooperation between the second rotating member 52 and the first rotating member 51, the second rotating member 52 is driven to rotate counterclockwise relative to the base plate 10, which in turn drives the logo cover plate 53 to rotate counterclockwise relative to the base plate 10, so that the logo cover plate 53 covers the corresponding opening of the logo assembly 30, making the covering of the opening by the logo covering assembly 50 simpler and more reliable.
[0055] Combination Figure 1 as well as Figures 3-6As shown, the length of the second track 43 is L4, and L4 satisfies the relationship: 50mm≤L4≤70mm. Specifically, setting the length of the second track 43 within a reasonable range not only ensures the sliding length of the sliding part 21 relative to the second track 43, ensuring that the logo assembly 30 descends a sufficient distance relative to the base plate 10, preventing the retracted logo assembly 30 from obstructing the operation of other components within the vehicle logo device 100, but also prevents the second track 43 from being too long, increasing the space occupied by the vehicle logo device 100, thus ensuring the structural compactness of the vehicle logo device 100.
[0056] Combination Figure 1 As shown, the running track 40 is provided with multiple mounting portions 44. Along the length extension direction of the running track 40, the mounting portions 44 are staggered on both sides of the running track 40, and all mounting portions 44 are mounted on the base plate 10. Specifically, the running track 40 and the sliding portion 21 slide against each other, and the running track 40 is subjected to contact force from the sliding portion 21. By providing multiple mounting portions 44 on the running track 40, and staggering the mounting portions 44 along the length extension direction of the running track 40, and mounting all mounting portions 44 on the base plate 10, not only can the installation of the running track 40 on the base plate 10 be achieved, ensuring the stability and reliability of the installation of the running track 40 on the base plate 10, but also, through the staggered arrangement of the multiple mounting portions 44, the force on the running track 40 and the base plate 10 is made more uniform, thereby improving the reliability of the sliding cooperation between the sliding portion 21 and the running track 40, and improving the reliability of the vehicle emblem device 100.
[0057] The vehicle according to an embodiment of the present invention may mainly include: the vehicle emblem device 100 described above. Specifically, the vehicle emblem device 100 can be applied to the vehicle. By optimizing the structure of the running track 40, not only can the smoothness and stability of the raising and lowering of the emblem component 30 relative to the vehicle body be improved, thus enhancing the reliability of the vehicle, but also the structural compactness of the vehicle can be improved, thereby enhancing the product competitiveness of the vehicle.
[0058] Based on the above introduction of the car logo and related structures, the following combines... Figure 7 The present invention describes a method for controlling a vehicle logo according to an embodiment of the invention. The vehicle logo is, for example, the vehicle logo component 30 described in the above embodiment, which can move relative to the substrate 10.
[0059] Figure 7 This is a flowchart of a vehicle logo control method according to an embodiment of the present invention. Figure 7 As shown, a method for controlling a vehicle emblem, the emblem being configured to rise or fall along a running track under the drive of a motor, the method comprising the following steps:
[0060] Step S1: In response to the logo operation control command, control the logo to operate.
[0061] Specifically, when the logo controller receives the logo operation control command, it controls the motor to run, and the logo rises or falls along the running track under the drive of the motor.
[0062] Step S2: During the operation of the car logo, obtain the operation information of the car logo.
[0063] Step S3: Control the running speed of the car logo based on its running information.
[0064] Specifically, as the logo rises or falls along the track, the logo controller acquires the logo's movement information and controls its speed accordingly. This prevents vibration during ascent or descent, ensuring the logo reaches its target position smoothly and improving its reliability. Specifically, controlling the logo's speed can be achieved by controlling the aforementioned drive components. The specific drive structure and principles are detailed above and will not be repeated here.
[0065] In one embodiment of the present invention, obtaining the running information of the vehicle logo includes: obtaining the location information or running time information of the vehicle logo.
[0066] Specifically, as the logo rises or falls along the track, the logo controller acquires the logo's position information or running time information, and controls the logo's running speed based on this information to prevent vibration during ascent or descent, thus ensuring the logo reaches the target position smoothly and improving its reliability. For example, the logo's position information can be acquired through a position sensor, and the running time information can be acquired through a timer.
[0067] In one embodiment of the present invention, controlling the running speed of the vehicle logo according to the running information of the vehicle logo includes: controlling the vehicle logo to have different running speeds in different parts of the running track according to the running information of the vehicle logo.
[0068] Specifically, to prevent the logo from vibrating during its ascent or descent, it needs to have different running speeds at different points on the track. For example, the track can be divided into a front, middle, and / or rear section. During the ascent, when the logo is in the front section of the track, its speed is gradually increased to the target speed, meaning it rises slowly from the starting point. When it reaches the middle section, it continues at the target speed. When it reaches the rear section, its speed gradually decreases to zero, ensuring a smooth ascent to the end point. Similarly, during the descent, the speed is gradually increased to the target speed in the front section of the track, meaning it descends slowly from the starting point. When it reaches the middle section, it continues at the target speed. When it reaches the rear section, its speed gradually decreases to zero, ensuring a smooth descent to the end point.
[0069] In one embodiment of the present invention, the running track includes a first track and a second track, with one end of the first track and one end of the second track smoothly connected by a trajectory change segment; when the car logo rises, the car logo is controlled to move from the other end of the first track to the other end of the second track; when the car logo falls, the car logo is controlled to move from the other end of the second track to the other end of the first track.
[0070] Specifically, the first track and the second track have different slopes and are smoothly connected through track change segments. The ascending track and the descending track of the car logo are the same track, that is, the ascending track extends from the other end of the first track to the other end of the second track, and the descending track is in the opposite direction to the ascending track, that is, the descending track extends from the other end of the second track to the other end of the first track.
[0071] In one embodiment of the present invention, the vehicle logo is controlled to have different running speeds at different parts of the running track according to the running information of the logo, including: when the logo rises, the running speed of the logo is controlled to gradually increase from zero until the logo reaches a preset distance from the other end of the first track or the running time of the logo reaches a first preset time, then the logo is controlled to run at a preset target speed until the logo reaches a preset distance from the other end of the second track or the running time of the logo reaches a second preset time, then the running speed of the logo is controlled to gradually decrease from the target speed until the running speed corresponding to the logo reaching the other end of the second track or the running time of the logo reaches a third preset time is zero.
[0072] Specifically, when the logo rises, it uses the other end of the first track as the starting point and the other end of the second track as the ending point. When the logo reaches a preset distance from the other end of the first track (e.g., the first 1 / 3 of the way up), or when the logo's running time reaches a first preset time (e.g., 500ms), the logo's speed is gradually increased from zero to a target speed, meaning the logo slowly rises from the starting point of the track. Then, the logo runs at the target speed until it reaches a preset distance from the other end of the second track (e.g., the first 1 / 3 of the way up), or when the logo's running time reaches a third preset time (e.g., 500ms before reaching the ending point), the logo's rising speed is gradually reduced from the target speed to zero. When the logo's rising speed reaches zero, it reaches the other end of the second track, the ending point. Just before reaching the ending point, the logo slowly stops rising to avoid vibration during the ascent.
[0073] In one embodiment of the present invention, the vehicle logo is controlled to have different running speeds at different parts of the running track according to the running information of the logo, including: when the logo descends, the running speed of the logo is controlled to gradually increase from zero until the logo reaches a preset distance from the other end of the second track or the running time of the logo reaches a fourth preset time, then the logo is controlled to run at a preset target speed until the logo reaches a preset distance from the other end of the first track or the running time of the logo reaches a fifth preset time, then the running speed of the logo is controlled to gradually decrease from the target speed until the running speed corresponding to the logo reaching the other end of the first track or the running time of the logo reaches a sixth preset time is zero.
[0074] Specifically, when the logo descends, it uses the other end of the second track as the starting point and the other end of the first track as the ending point. When the logo reaches a preset distance from the other end of the second track (e.g., the first third of the track), or when the logo's running time reaches a fourth preset time (e.g., 500ms), the logo's speed is gradually increased from zero to the target speed, meaning the logo slowly descends from the starting point of the track. Then, the logo continues at the target speed until it reaches a preset distance from the other end of the first track (e.g., the first third of the track), or when the logo's running time reaches a sixth preset time (e.g., 500ms before reaching the end point), the descent speed is gradually reduced from the target speed to zero. When the descent speed reaches zero, the logo reaches the other end of the first track, the ending point of the descent. Just before reaching the end point, the logo slowly stops descending to avoid vibration during the descent.
[0075] In one embodiment of the invention, the first track is constructed as a circular arc track, and the second track is constructed as a straight track.
[0076] Specifically, the circular track and the straight track have different slopes and are smoothly connected through track change segments. The ascending track and descending track of the car logo are the same track, that is, the ascending track extends from the other end of the circular track to the other end of the straight track, and the descending track is in the opposite direction to the ascending track, that is, the descending track extends from the other end of the straight track to the other end of the circular track.
[0077] In one embodiment of the present invention, the running speed of the car logo is controlled by controlling the rotational speed of the motor.
[0078] Specifically, the faster the motor speed, the faster the logo moves. When the logo rises or falls, the motor speed can be gradually increased from zero to raise the logo's speed to the target speed. Then, the motor speed is kept constant to maintain the target speed. Finally, the motor speed is gradually reduced to zero to lower the logo's speed from the target speed to zero. This gradual increase and decrease prevents vibration during ascent or descent, ensuring the logo reaches its target position smoothly and improving its reliability.
[0079] In one embodiment of the present invention, the speed of the motor is controlled by controlling the voltage duty cycle of the motor drive. That is, when the logo starts slowly, the voltage duty cycle of the motor drive is gradually increased from 0% to the voltage duty cycle corresponding to the target speed. When the logo stops slowly, the voltage duty cycle of the motor drive is gradually decreased to 0% to avoid vibration of the logo during the rising or falling process and ensure that the logo reaches the target position smoothly.
[0080] In one embodiment of the invention, the motor is configured as a dual Hall effect motor.
[0081] Specifically, the logo controller determines the motor's rotation speed by collecting the pulse width of the motor's Hall effect sensors, thereby controlling the logo's running speed. In a specific embodiment, the phase difference between the two Hall sensors in the dual-Hall motor is 90°. Therefore, during motor operation, the rotation direction can be determined by the phase difference between the two Hall sensors. The Hall sensors acquire the logo's position information through counting. Under normal circumstances, the counts of the two Hall sensors in the dual-Hall motor are consistent. If they are inconsistent, the larger count value is used, and the Hall sensor that lost data is corrected by comparison. Thus, the dual-Hall sensors can accurately acquire the logo's position information, facilitating precise control of the logo's rotation speed.
[0082] According to the vehicle logo control method of the present invention, during the operation of the vehicle logo, by acquiring the operation information of the vehicle logo and controlling the operation speed of the vehicle logo according to the operation information, vibration of the vehicle logo during the rising or falling process can be avoided, thereby ensuring that the vehicle logo reaches the target position smoothly and improving the reliability of the vehicle logo.
