Method and device for controlling a vehicle badge and vehicle

Abstract

This invention proposes a method, device, and vehicle for controlling a vehicle logo. The method includes: determining the count value of a thermal protection counter based on the operating state of a drive motor; and controlling the drive motor to run or stop based on the relationship between the count value and a preset count threshold, thereby controlling the operating state of the vehicle logo accordingly. By determining and setting the count value of the thermal protection counter, this invention controls the drive motor to run or stop during operation based on the obtained count value. When the count value is too high, an overheat protection function is activated, i.e., the drive motor is stopped, thus stopping the vehicle logo. This reduces the heat generated by the drive motor, avoids motor damage caused by overheating, and improves the safety of the drive motor operation while ensuring the reliability of the vehicle logo's operation.

Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method and device for controlling vehicle logos and a vehicle. 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 important components that enhance brand recognition and reflect the vehicle's refinement and technological sophistication.

[0003] The lifting and rotation of the car logo are driven by a corresponding drive mechanism. Due to the complex structure of the drive mechanism, the running resistance is large when driving the car logo. After long-term or frequent operation, overheating is likely to occur. In addition, the car logo is exposed to the outside throughout the entire operation process, and debris can easily enter and cause the drive mechanism to jam, which increases the running resistance. If the motor continues to run, the motor is likely to overheat and burn out. Summary of the Invention

[0005] Therefore, the first objective of this invention is to provide a method for controlling vehicle logos.

[0006] Therefore, a second objective of the present invention is to provide a control device for vehicle logos.

[0007] Therefore, a third objective of the present invention is to provide a vehicle.

[0008] To achieve the above objectives, an embodiment of the first aspect of the present invention provides a method for controlling a vehicle logo, wherein the vehicle logo is configured to be liftable and / or rotatable along a logo rotation axis, the vehicle logo is connected to a drive assembly, the drive assembly including a drive motor for providing driving force for the operation of the vehicle logo, and the method includes: determining a count value of a thermal protection counter based on the operating state of the drive motor; and controlling the drive motor to operate or stop based on the relationship between the count value and a preset count threshold, so as to control the operating state of the vehicle logo accordingly.

[0009] According to the vehicle logo control method of the present invention, by determining the count value of the thermal protection counter, during the operation of the drive motor, the drive motor is controlled to run or stop according to the magnitude of the obtained count value of the thermal protection counter. When the count value is too large, the overheat protection function is activated, that is, the drive motor is controlled to stop running, so as to control the vehicle logo to stop. This reduces the heat generated by the drive motor movement and avoids motor damage caused by overheating of the drive motor. While improving the safety of drive motor operation, the reliability of vehicle logo operation is also guaranteed.

[0010] In some embodiments, controlling the drive motor to move or stop based on the relationship between the count value and a preset count threshold includes: when the count value is greater than a preset first count threshold, controlling the drive motor to stop based on the current operating state of the drive motor.

[0011] In some embodiments, controlling the drive motor to stop based on its current operating state includes: if the current state of the drive motor is running, controlling the drive motor to stop after the current action is completed, and entering a disabled state after stopping, controlling the drive motor to remain in the disabled state to prevent the drive motor from running, until the count value of the thermal protection counter is less than a preset second count threshold, then controlling the drive motor to release the disabled state to allow the drive motor to run; if the current state of the drive motor is stopped, directly controlling the drive motor to enter a disabled state to prevent the drive motor from running until the count value of the thermal protection counter is less than the preset second count threshold, then controlling the drive motor to release the disabled state to allow the motor to run, wherein the first count threshold is greater than the preset second count threshold.

[0012] In some embodiments, determining the count value of the thermal protection counter based on the operating state of the drive motor includes: when the drive motor is running, controlling the count value of the thermal protection counter to increase at first preset time intervals according to a first preset step size, and determining the count value of the thermal protection counter based on the running time of the drive motor.

[0013] In some embodiments, determining the count value of the thermal protection counter based on the operating state of the drive motor further includes: when a stall of the drive motor is detected during the operation of the drive motor, controlling the count value of the thermal protection counter to increase according to a second preset step size based on the number of stalls of the drive motor; and determining the count value of the thermal protection counter based on the operating time of the drive motor and the number of stalls of the drive motor.

[0014] In some embodiments, after controlling the drive motor to enter a disabled state, the method further includes: controlling the count value of the thermal protection counter to decrease at a third preset time interval according to a third preset step size, until the count value of the thermal protection counter is less than the preset second count threshold, wherein the third preset step size is less than the first preset step size.

[0015] In some embodiments, the preset second counting threshold is half of the first counting threshold.

[0016] In some embodiments, the driving assembly includes a car logo lifting driving assembly and a car logo rotating driving assembly, and the driving motor includes a lifting driving motor and a rotating driving motor. The lifting driving motor is used to provide driving force for lifting the car logo, and the rotating driving assembly is used to provide driving force for rotating the car logo along the rotating axis. The car logo is disposed on the car logo rotating driving assembly, and the car logo is in a transmission engagement with the car logo rotating driving assembly to rotate along the car logo rotating axis under the drive of the car logo rotating driving assembly. The car logo is electrically connected to a car logo position detection assembly to detect whether the car logo is in an extended state or a retracted state.

[0017] In some embodiments, the logo position detection component includes a position detector and a controller. The position detector is used to detect the position of the logo. The controller is electrically connected to the position detector and the logo rotation drive component. When the position detector detects that the logo is in an extended state, the controller controls the logo rotation drive component to drive the logo to rotate.

[0019] According to the vehicle logo control device of the present invention, by determining the count value of the thermal protection counter, the device controls the drive motor to run or stop during the operation of the drive motor based on the magnitude of the obtained count value of the thermal protection counter. When the count value is too large, the overheat protection function is activated, that is, the drive motor is controlled to stop running, thereby controlling the vehicle logo to stop. This reduces the heat generated by the drive motor and avoids motor damage caused by overheating. While improving the safety of the drive motor operation, the device also ensures the reliability of the vehicle logo operation.

[0034] 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.

[0035] The vehicle logo is a three-dimensional logo, which can be set on the top of the vehicle's engine compartment and configured to rotate along a vertically oriented logo rotation axis. Specifically, the logo, the logo rotation axis, and the related drive mechanism are all components of the logo device 100, and the logo and the logo rotation axis can be driven by the related drive mechanism in the logo device.

[0036] The following provides an example illustrating the structure of the relevant vehicle logo device. (For reference...) Figure 1 and Figure 2 The lifting and rotating process of the vehicle logo in an embodiment of the present invention is illustrated by example.

[0037] Combination Figure 1 and Figure 2 As shown, the car logo device 100 includes a base plate 10, a car logo 30, a car logo lifting drive assembly 70, a car logo rotating drive assembly 31, and a car logo position detection assembly 50. The car logo lifting drive assembly 70 is movably disposed on the base plate 10. The car logo rotating drive assembly 31 is driven by the car logo lifting drive assembly 70 to lift and lower relative to the base plate 10 under the drive of the car logo lifting drive assembly 70. The car logo 30 is disposed on the car logo rotating drive assembly 31. The car logo 30 is driven by the car logo rotating drive assembly 31 to rotate relative to the base plate 10 under the drive of the car logo rotating drive assembly 31.

[0038] Specifically, the logo 30 is placed on the logo rotation drive assembly 31, and the logo rotation drive assembly 31 is driven by the logo lifting drive assembly 70. This allows the logo rotation drive assembly 31 to rise and fall relative to the base plate 10 under the drive of the logo lifting drive assembly 70, thereby allowing the logo 30 to rise and fall under the drive of the logo rotation drive assembly 31. Furthermore, since the logo 30 and the logo rotation drive assembly 31 are driven by the rotation, the logo rotation drive assembly 31 can also drive the logo 30 to rotate. This not only makes the lifting and rotation of the logo 30 more reliable, but also simplifies the structural design of the logo device 100. Understandably, the movement of the logo lifting drive assembly 70 is driven by the lifting drive motor, and the movement of the logo rotation drive assembly 31 is driven by the rotation drive motor. When the logo is lifted and / or rotates along the logo rotation axis, the lifting drive motor drives the logo lifting drive assembly to move in order to achieve lifting control of the logo, and / or the rotation drive motor drives the logo rotation drive assembly to move in order to achieve rotation control of the logo along the rotation axis.

[0039] Furthermore, the logo position detection component 50 is used to detect the position of the logo 30. The logo position detection component 50 is electrically connected to the logo rotation drive component 31. When the logo position detection component 50 detects that the logo 30 is in an extended state, the logo rotation drive component 31 drives the logo 30 to rotate. Specifically, when the logo 30 is in an extended state, the logo 30 is located on the outside of the vehicle. When the logo position detection component 50 detects that the logo 30 is in a display position, it can send an electrical signal to the logo rotation drive component 31, thereby causing the logo rotation drive component 31 to drive the logo 30 to rotate. This configuration allows the logo 30 to rotate while in an extended state, which not only improves the performance of the logo device 100 but also makes the rotation of the logo 30 more reliable and intelligent.

[0040] In addition, with this configuration, the lifting and rotation of the logo 30 are relatively independent. That is, the lifting and rotation of the logo 30 are achieved through two power sources, which do not interfere with each other. This can improve the independence and stability of the lifting and rotation of the logo 30.

[0041] Therefore, by electrically connecting the logo position detection component 50 and the logo rotation drive component 31, when the logo 30 is in the extended state, the logo rotation drive component 31 can drive the logo 30 to rotate. This not only makes the rotation of the logo 30 in the extended state more reliable, but also simplifies the structure of the logo device 100.

[0042] The car logo lifting drive assembly 70 can mainly include: a lifting drive mechanism 20 and a lifting transmission mechanism 40. The lifting drive mechanism 20 is disposed on the base plate 10. The lifting transmission mechanism 40 can mainly include: a drive linkage group 41, an active linkage group 42 and a driven linkage 43. The two ends of the drive linkage group 41 are respectively connected to the lifting drive mechanism 20 and the active linkage group 42. The two ends of the active linkage group 42 are respectively connected to the car logo 30 and the base plate 10. One end of the driven linkage 43 is connected to the car logo 30, and the other end of the driven linkage 43 is slidably disposed in the first slide groove 11 to change the rotation axis of the lifting transmission mechanism 40. In this way, the lifting drive mechanism 20 and the active linkage group 42 are in transmission cooperation, which can drive the linkage group 41 to rotate and further drive the active linkage group 42 to move up and down, thereby driving the car logo 30 to move, realizing the lifting and lowering of the car logo 30 relative to the base plate 10, so that the car logo 30 can be selectively located on the upper part of the vehicle engine compartment top cover and the lower part of the car logo engine compartment top cover.

[0043] Among them, combined Figure 1 and Figure 2As shown, the drive linkage assembly 41 mainly includes: a first drive rod 411 and a second drive rod 412. Both ends of the first drive rod 411 are connected to the lifting drive mechanism 20 and one end of the second drive rod 412, while the other end of the second drive rod 412 is connected to the active linkage assembly 42. By connecting both ends of the first drive rod 411 to the lifting drive mechanism 20 and one end of the second drive rod 412 respectively, and connecting the other end of the second drive rod 412 to the active linkage assembly 42, the power of the lifting drive mechanism 20 can be transmitted sequentially to the active linkage assembly 42 through the first drive rod 411 and the second drive rod 412, driving the active linkage assembly 42 to move. This makes the power transmission of the drive linkage assembly 41 simpler and more efficient.

[0044] The active linkage assembly 42 may mainly include: a first active rod 421, a second active rod 422, and an anti-theft actuator 423. One end of the first active rod 421 is connected to the base plate 10, and the drive linkage assembly 41 is connected to the first active rod 421. The other end of the first active rod 421 is selectively connected to the anti-theft actuator 423. The anti-theft actuator 423 is disposed on the second active rod 422. The two ends of the second active rod 422 are rotatably connected to the vehicle emblem 30 and the base plate 10, respectively.

[0045] Specifically, the drive linkage 41 is connected to the first active rod 421. One end of the first active rod 421 is connected to the base plate 10, and the other end of the first active rod 421 is selectively connected to the anti-theft actuator 423. The anti-theft actuator 423 is set on the second active rod 422, and the two ends of the second active rod 422 are rotatably connected to the car emblem assembly 30 and the base plate 10, respectively. In this way, the first active rod 421 can rotate relative to the base plate 10 under the drive of the drive linkage 41, and further drive the anti-theft actuator 423 and the second active rod 422 to rotate relative to the base plate 10. The car emblem assembly 30 can move relative to the base plate 10 under the action of the second active rod 422, thereby making the lifting and lowering of the car emblem assembly 30 more stable and reliable.

[0046] Based on the structure of the above-described vehicle logo device, the following is an example of the vehicle logo control method according to an embodiment of the present invention.

[0047] The following is combined Figure 3 The vehicle logo control method of the present invention is described in the following embodiments: Figure 3 As shown, the vehicle logo control method of this embodiment includes at least step S1 and step S2.

[0048] Step S1: Determine the count value of the thermal protection counter based on the operating status of the drive motor. The drive motor includes a lifting drive motor or a rotating drive motor. The lifting drive motor is used to provide driving force for the lifting of the car logo, and the rotating drive motor is used to provide driving force for the rotation of the car logo along the rotating axis.

[0049] The count value of the thermal protection counter can indicate the operating status of the drive motor to a certain extent, such as whether the drive motor is overheating. If the count value of the thermal protection counter is very large, it is considered that the drive motor may be overheating. Therefore, by obtaining the count value of the thermal protection counter, the operating status of the drive motor can be judged.

[0050] In the embodiments, when the drive motor operates frequently or for a long time, the motor may overheat. Alternatively, when the logo lifting drive assembly and the logo rotating drive assembly control the movement of the logo, the transmission of the logo lifting drive assembly and the logo rotating drive assembly may become stuck. In this case, the resistance of the drive motor increases during operation, which can easily cause the drive motor to overheat. Alternatively, the logo lifting drive assembly and the logo rotating drive assembly may become stuck due to the entry of foreign objects, which can also easily cause the drive motor to overheat. In this case, by determining the count value of the thermal protection counter, it is convenient to implement the corresponding protection strategy for the drive motor based on the count value of the thermal protection counter.

[0051] Step S2: Based on the relationship between the count value and the preset count threshold, control the drive motor to run or stop, so as to control the running status of the car logo accordingly.

[0052] The preset counting threshold is the count value of the thermal protection counter, which includes a first counting threshold and a second counting threshold. When the count value of the thermal protection counter reaches the preset first counting threshold, it is considered that the drive motor may be at risk of overheating and damage.

[0053] In this embodiment, after determining the count value of the thermal protection counter, the count value of the thermal protection counter is compared with a preset count threshold. When the count value of the thermal protection counter exceeds the preset first count threshold, it is considered that the continued operation of the drive motor may cause damage to the drive motor. At this time, it is necessary to adopt an appropriate control strategy for the drive motor, such as controlling the drive motor to stop, in order to reduce the count value of the thermal protection counter.

[0054] When the count value of the thermal protection counter does not exceed the preset first count threshold, it is considered that the drive motor can continue to run. At this time, the drive motor is controlled to run in order to control the movement of the car logo.

[0055] Understandably, by determining the relationship between the count value and the preset count threshold, the operating state of the drive motor can be controlled to control the operating state of the car logo. When the count value is high, such as exceeding the preset first count threshold, the drive motor can be stopped to reduce the heat generated by the drive motor and avoid motor damage caused by overheating, thereby ensuring the safety of motor operation and, in turn, the reliability of the car logo operation.

[0056] According to the vehicle logo control method of the present invention, by determining the count value of the thermal protection counter, during the operation of the drive motor, the drive motor is controlled to run or stop according to the magnitude of the obtained count value of the thermal protection counter. When the count value is too large, the overheat protection function is activated, that is, the drive motor is controlled to stop running, so as to control the vehicle logo to stop. This reduces the heat generated by the drive motor movement and avoids motor damage caused by overheating of the drive motor. While improving the safety of drive motor operation, the reliability of vehicle logo operation is also guaranteed.

[0057] In some embodiments, controlling the drive motor to move or stop based on the relationship between the count value and a preset count threshold includes: controlling the drive motor to stop based on the current operating state of the drive motor when the count value is greater than a preset first count threshold.

[0058] For example, based on the temperature rise curve of the drive motor, a thermal protection strategy can be set. For instance, a preset first counting threshold can be set, and the count value of the thermal protection counter can be obtained. When the count value is greater than the first counting threshold, it is considered that the drive motor may be overheating. At this time, it is necessary to determine the current state of the drive motor and control the drive motor to stop based on the current operating state of the drive motor.

[0059] If the drive motor is currently running, it will stop after the current action is completed and enter a disabled state. The drive motor will remain disabled to prevent it from running until the thermal protection counter's count value falls below a preset second threshold. At this point, the drive motor will be released from the disabled state to allow it to run. It can be understood that if the count value is greater than the first threshold and the drive motor is running, controlling it to enter the disabled state after the current action is completed can prevent the logo from suddenly stopping during movement, thus affecting the user experience. In this case, the drive motor remains disabled. When the drive motor is disabled, its temperature gradually decreases until the thermal protection counter drops below a second threshold. At this point, the drive motor is considered to be free from overheating, and its operation is restored. By setting a second threshold, the drive motor is de-disabled when the thermal protection counter's value falls below this threshold. This prevents the drive motor from remaining in a disabled state and unable to restart, thus achieving intelligent recovery of the drive motor and automatically restoring it to normal operation once its temperature decreases.

[0060] If the drive motor is currently in a stopped state, it is directly controlled to enter a disabled state to prevent its operation until the thermal protection counter's count value falls below a preset second count threshold. At this point, the drive motor is released from the disabled state to allow it to run. The first count threshold is greater than the preset second count threshold. Essentially, when the count value is greater than the first count threshold and the drive motor is stopped, it is directly controlled to enter a disabled state to prevent overheating. Once the thermal protection counter's count value falls below the second count threshold, the motor is allowed to run, thus protecting it from overheating and improving its operational reliability. The second count threshold is typically half the first count threshold; for example, if the first count threshold is 120,000, the second count threshold is 60,000.

[0061] In some embodiments, determining the count value of the thermal protection counter based on the operating state of the drive motor includes: when the drive motor is running, controlling the count value of the thermal protection counter to increase at first preset time intervals according to a first preset step size, and determining the count value of the thermal protection counter based on the running time of the drive motor.

[0062] In this embodiment, when the drive motor is running normally, the count value of the thermal protection counter is increased by a first preset step size every first preset time interval. For example, the count value of the thermal protection counter is increased by 2 every 10ms. The count value of the thermal protection counter is determined according to the running time of the drive motor. When the count value is greater than the first counting threshold, the increase is stopped. The drive motor is then stopped according to the current running state of the drive motor.

[0063] In some embodiments, determining the count value of the thermal protection counter based on the operating state of the drive motor further includes: when a stall of the drive motor is detected during the operation of the drive motor, controlling the count value of the thermal protection counter to increase according to a second preset step size based on the number of stalls of the drive motor; and determining the count value of the thermal protection counter based on the operating time of the drive motor and the number of stalls of the drive motor.

[0064] In this embodiment, when the drive motor is running, under normal circumstances, the count value of the thermal protection counter is increased by a first preset step size every first preset time. If a stall is detected in the drive motor during operation, the count value of the thermal protection counter is increased by a second preset step size. For example, the count value of the thermal protection counter is increased by 50 every time a stall is detected. At this time, the count value of the thermal protection counter is determined according to the running time and the number of stalls of the drive motor. The count value is increased until it exceeds the first counting threshold, at which point the increase stops, and the drive motor is stopped according to its current operating state.

[0065] If no drive motor stall is detected during operation, the thermal protection counter's count value is increased by a first preset step size every first preset time interval until the count value exceeds a first counting threshold. It is understood that by setting the first preset step size to be smaller than a second preset step size, the thermal protection counter's count value can be increased quickly when the drive motor stalls, preventing prolonged stalling and slow count increases that could prevent the count value from reaching the first counting threshold and causing overheating of the drive motor. This improves the safety of drive motor operation.

[0066] In some embodiments, after controlling the drive motor to enter a disabled state, the method further includes: controlling the count value of the thermal protection counter to decrease at a third preset time interval according to a third preset step size, until the count value of the thermal protection counter is less than a preset second count threshold, wherein the third preset step size is less than the first preset step size.

[0067] In this embodiment, when the drive motor is running, if the overheat protection counter enters a disabled state due to an excessively high count value, the count value of the overheat protection counter is reduced by a third preset step size every third preset time interval. For example, the count value of the overheat protection counter is reduced by 1 every 10ms. By setting the third preset step size to be smaller than the first preset step size, sufficient time is provided for the drive motor to cool down, avoiding the situation where the temperature of the drive motor is still high after the count value quickly reaches the second counting threshold.

[0068] The following is for reference. Figure 4 A flowchart describing the vehicle logo control method according to an embodiment of the present invention.

[0069] Step S11, Begin.

[0070] Step S12: Determine whether a stall in the drive motor is detected. If yes, proceed to step S13; otherwise, proceed to step S20.

[0071] Step S13: Control the thermal protection counter to increase its count value according to the second preset step size.

[0072] Step S14: Determine whether the count value of the thermal protection counter is greater than the first count threshold. If yes, proceed to step S15; otherwise, proceed to step S20.

[0073] Step S15: Control the drive motor to stop according to the current operating status of the drive motor.

[0074] Step S16: Determine whether the drive motor is in operation. If yes, proceed to step S17; otherwise, proceed to step S19.

[0075] Step S17: Control the drive motor to run until the current action ends and then stop. After stopping, enter the disabled state and control the drive motor to remain in the disabled state to prevent the drive motor from running.

[0076] Step S18: Every third preset time interval, the count value of the thermal protection counter is controlled to decrease according to the third preset step size until the count value of the thermal protection counter is less than the preset second counting threshold.

[0077] Step S19: Directly control the drive motor to enter the disabled state to prevent the drive motor from running until the count value of the thermal protection counter is less than the preset second count threshold. Then, control the drive motor to release the disabled state to allow the motor to run.

[0078] Step S20: Every first preset time interval, the count value of the thermal protection counter is increased according to the first preset step size.

[0079] Step S21, End.

[0080] According to the vehicle logo control method of the present invention, a thermal protection counter is set up. During the operation of the drive motor, the drive motor is controlled to run or stop according to the value of the thermal protection counter. When the count value is too large, the overheat protection function is activated, that is, the drive motor is controlled to stop running, so as to control the vehicle logo to stop. This reduces the heat generated by the drive motor and avoids motor damage caused by overheating. While improving the safety of motor operation, the reliability of vehicle logo operation is also guaranteed.

[0081] The following describes the vehicle logo control device according to an embodiment of the present invention.

[0082] like Figure 5 As shown, the vehicle logo control device 2 of this embodiment includes a determining module 20 and a control module 21. The determining module 20 is used to determine the count value of the thermal protection counter according to the operating state of the drive motor. The control module 21 is used to control the drive motor to run or stop according to the relationship between the count value and a preset count threshold, so as to control the operating state of the vehicle logo accordingly.

[0083] According to the embodiment of the present invention, the vehicle logo control device 2 determines the count value of the thermal protection counter. During the operation of the drive motor, it controls the drive motor to run or stop based on the magnitude of the obtained count value of the thermal protection counter. When the count value is too large, the overheat protection function is activated, that is, the drive motor is controlled to stop running, so as to control the vehicle logo to stop. This reduces the heat generated by the drive motor and avoids motor damage caused by overheating. While improving the safety of the drive motor operation, it also ensures the reliability of the vehicle logo operation.

[0084] The vehicle according to an embodiment of the present invention is described below.

[0085] like Figure 6 As shown, the vehicle logo 3 in this embodiment of the invention includes the control device 2 for the vehicle logo in the above embodiment.

[0086] According to the vehicle 3 of the present invention, by determining the count value of the thermal protection counter, during the operation of the drive motor, the drive motor is controlled to run or stop according to the magnitude of the obtained count value of the thermal protection counter. When the count value is too large, the overheat protection function is activated, that is, the drive motor is controlled to stop running, so as to control the car logo to stop, thereby reducing the heat generated by the movement of the drive motor and avoiding motor damage caused by overheating of the drive motor. While improving the safety of the drive motor operation, the reliability of the car logo operation is also guaranteed.
