[0020] Embodiment 1 See also Figures 1 to 7In one embodiment, a vehicle logo switching device is used to switch the vehicle logo at the vehicle logo opening of the external vehicle shell 10, including a base shell 1, a track guide part 4, a first vehicle logo carrier, a second vehicle logo carrier and a driving part 2.

[0021] The base shell 1 is configured to cooperate with the outer shell 10 to form a logo switching space, and the logo switching space is defined as having a horizontal length, a longitudinal width, and a vertical height.

[0022] The track guide portion 4 is mounted on the base shell 1 and forms a guide track located in the vehicle logo switching space, and the guide track includes a display track segment 7 located directly below the vehicle logo opening and a first switching track segment and a second switching track segment extending laterally outward at both ends of the display track segment 7. The height of at least part of the first switching track segment and at least part of the second switching track segment is lower than that of the display track segment 7.

[0023] The first vehicle logo carrier is configured to be limited by the track guide part 4 so as to move along the guide track. The second vehicle logo carrier is configured to be limited by the track guide part 4 so as to move along the guide track. The driving part 2 is installed on the base shell 1, and the output end of the driving part 2 is connected to the first vehicle logo carrier and the second vehicle logo carrier. The driving part 2 is configured to drive the first vehicle logo carrier and the second vehicle logo carrier to switch between the first display configuration and the second display configuration.

[0024] In the first display configuration, the output end of the drive unit 2 moves to the first position, the first car logo carrier is located in the first switching track segment, and the second car logo carrier is located in the display track segment 7 and corresponds to the vehicle shell opening. In the second display configuration, the output end of the drive unit 2 moves to the second position, the first car logo carrier is located in the display track segment 7 and corresponds to the vehicle shell opening, and the second car logo carrier is located in the second switching track segment.

[0025] In this embodiment, a base shell 1 is provided to cooperate with an external vehicle shell 10 to form a vehicle logo switching space, and a track guide part 4, a first vehicle logo carrier, a second vehicle logo carrier and a driving part 2 are provided in the vehicle logo switching space; a guide track including a first switching track segment, a display track segment 7 and a second switching track segment is formed on the track guide part 4, and the two switching track segments are arranged to extend laterally outward and at least partially lower than the display track segment 7 to serve as a temporary storage area for the vehicle logo, and the driving part 2 is used to drive the two vehicle logo carriers to move between the first display configuration and the second display configuration along the guide track; in the first display configuration, the first vehicle logo carrier is hidden in the first switching track segment, the second vehicle logo carrier is located in the display track segment 7 and the vehicle logo thereon is located at the vehicle logo opening of the external vehicle shell 10; In the second display configuration, the first vehicle logo carrier and the second vehicle logo carrier move to the other side as a whole, the first vehicle logo carrier moves to the display track segment 7 and the vehicle logo thereon is at the vehicle logo opening of the outer vehicle shell 10, and the second vehicle logo carrier moves and is hidden in the second switching track segment, thereby realizing the vehicle logo switching action. In addition, in this embodiment, since the moving direction is horizontal, the height difference between the two switching track segments relative to the display track segment 7 only needs to meet the thickness of the corresponding vehicle logo carrier, and the space occupied by the overall device in the height direction can be greatly reduced. Moreover, this form of structure that realizes vehicle logo switching by reciprocating motion along the guide track is also simpler than the scheme of lifting and lowering two vehicle logos, which solves the problems of complex mechanism and large space occupied in the height direction in the existing lifting and switching vehicle logo methods.

[0026] The specific structure of the vehicle logo switching device of this embodiment is further described below: In this embodiment, the base shell 1 may specifically include a bottom plate 101 and two connecting plates 102. The lower ends of the two connecting plates 102 are respectively connected to the bottom plate 101 and are located at both ends of the bottom plate 101 in the longitudinal direction, and the upper ends of the two connecting plates 102 are used to connect to the outer shell 10. That is, the bottom plate 101 and the two connecting plates 102 cooperate to form a rectangular space extending in the transverse direction and located on the bottom surface of the outer shell 10.

[0027] See also Figure 6 In this embodiment, the first switching track segment includes a first temporary storage segment 5 and a first transition segment 6. The first transition segment 6 is connected between the first temporary storage segment 5 and the display track segment 7. The first transition segment 6 extends outwards horizontally and tilts downward vertically relative to the display track segment 7. That is, the first temporary storage segment 5 and the display track segment 7 are parallel to each other, and the first temporary storage segment 5 is lower than the display track segment 7 in the vertical direction. The first transition segment 6 is an oblique line segment or an arc segment connected to the first temporary storage segment 5 and the display track segment 7, and an arc transition can be set at the connection position between the first transition segment 6 and the two.

[0028] The second switching track segment includes a second temporary storage segment 9 and a second transition segment 8, the second transition segment 8 is connected between the second temporary storage segment 9 and the display track segment 7, and the second transition segment 8 is horizontally outward and vertically inclined downward relative to the extension direction of the display track segment 7. That is, the second temporary storage segment 9 and the display track segment 7 are parallel to each other, and the second temporary storage segment 9 is lower than the display track segment 7 in the vertical direction. The second transition segment 8 is an oblique line segment or an arc segment connected to the second temporary storage segment 9 and the display track segment 7, and the connection position between the second transition segment 8 and the two can be set with an arc transition.

[0029] Among them, the first temporary storage section 5 and the second temporary storage section 9 are lower than the display track section 7, so that the corresponding vehicle logo carrier can be gradually lifted at the transition section and extended into the vehicle logo opening (from the perspective of the outside of the vehicle, that is, the vehicle logo on the vehicle logo carrier gradually enters the vehicle logo opening from the inside of the vehicle shell) when moving from the corresponding temporary storage section toward the display track section 7. That is, the height of the display track section 7 can meet the requirement of the vehicle logo entering the vehicle logo opening for display, and the display track section 7 only corresponds to the vehicle logo opening, and the transition sections on both sides have the function of making the vehicle logo gradually enter the vehicle logo opening, and the two outermost temporary storage sections are hidden under the vehicle shell.

[0030] In this embodiment, the specific structure of the track guide part 4 may include a first track plate 401 and a second track plate 402. The first track plate 401 and the second track plate 402 are both arranged in the horizontal direction and are arranged on both sides of the driving part 2 respectively. The first track plate 401 and the second track plate 402 are respectively formed with a first track groove 403 and a second track groove on the surface facing the driving part 2. The extension direction of the first track groove 403 and the second track groove matches the guide track, and the sliding connection can be achieved by setting a corresponding slider 203 or a pulley or other structure on the vehicle logo carrier. In other embodiments, guide rails can also be set on the first track plate 401 and the second track plate 402, and this can be achieved by setting a corresponding pulley on the vehicle logo carrier, which is not specifically limited here.

[0031] Furthermore, in order to minimize the gap between the vehicle logo opening and the vehicle logo as much as possible, and reduce the contact wear between the vehicle logo and the vehicle shell caused by the shaking or vibration of the vehicle logo during rapid switching, the above-mentioned track guide part 4 may also include a first mounting seat, a second mounting seat, a tail shaft 406 and an elastic support member 407.

[0032] The first mounting seat and the second mounting seat are respectively mounted on the base shell 1 and are located on both sides of the driving part 2. The head end of the first track plate 401 is rotatably connected to the first mounting seat and the rotation axis is parallel to the longitudinal direction, and the head end of the second track plate 402 is connected to the first mounting seat and the rotation axis is parallel to the longitudinal direction. The two ends of the tail shaft 406 are respectively connected to the tail end of the first track plate 401 and the tail end of the second track plate 402. The elastic support member 407 is connected between the tail shaft 406 and the base shell 1, and the elastic support member 407 is configured to provide the supporting force required by the tail shaft 406 and has a compression stroke and a tension stroke. The elastic member can be specifically a spring or other component that can output the elastic member. That is, the first track plate 401 and the second track plate 402 can both swing around the connection position between them and the corresponding mounting seat, and the swing amplitude is limited to a certain extent by the elastic support member 407, so that the vibration generated by the driving part 2 when driving the first vehicle logo carrier and the second vehicle logo carrier to move can be absorbed by the elastic member, and when the corresponding vehicle logo carrier is in the process of rapid movement, the impact force formed on the vehicle logo carrier can be absorbed to a certain extent, thereby improving its service life.

[0033] In this embodiment, the driving part 2 may specifically include a linear drive mechanism and an intermediate transmission member 204. The linear drive mechanism is installed on the base shell 1, and the output end of the linear drive mechanism is configured to output a linear motion in the lateral direction. The intermediate transmission member 204 has a transmission input end and two transmission output ends. The transmission input end is rotationally connected to the output end of the linear drive mechanism and the rotation axis is parallel to the longitudinal direction. The two transmission output ends are rotationally connected to the first vehicle logo carrier and the second vehicle logo carrier respectively, and the rotation axis is parallel to the longitudinal direction. That is, the swing of the intermediate transmission member 204 relative to the output end of the linear drive mechanism is used to match the vertical height change of the first vehicle logo carrier and the second vehicle logo carrier when they move along the guide track.

[0034] Furthermore, the linear drive mechanism may specifically include a motor 201, a screw 202 and a slider 203. The motor 201 is mounted on the base shell 1, and the screw 202 is the output shaft of the motor 201. The motor 201 may specifically be a brushless motor 201 or a stepper motor 201. The slider 203 is threadedly connected to the screw 202 (the threaded transmission has a self-locking characteristic, which can keep the corresponding vehicle logo carrier stably located in the display track section 7), and at least one end of the slider 203 in the longitudinal direction is provided with a transmission shaft 205 rotatably connected to the transmission input end. Specifically, a transmission shaft 205 extending outward in the longitudinal direction may be respectively provided on the two end faces of the slider 203 in the longitudinal direction, and the two transmission shafts 205 are respectively rotatably connected to the transmission input end of the intermediate transmission member 204.

[0035] Further, see Figure 4The intermediate transmission member 204 may be a transmission plate 2041, which may be rectangular in shape. The transmission plate 2041 is provided with at least one transmission input arm 2042 extending downward, and the transmission input arm 2042 is configured to be rotatably connected to the output end of the linear drive mechanism (the number of the transmission input arms 2042 may be two, which are arranged on both sides of the transmission plate 2041 in the longitudinal direction and located in the middle area in the transverse direction, and the lower ends of the two transmission input arms 2042 may be provided with shaft holes, so as to realize the rotatable connection with the transmission shaft 205). At least one transmission output arm 2043 extending laterally outward is respectively provided at both ends of the transmission plate 2041 in the lateral direction, and the transmission output arms 2043 at both ends are respectively configured to be rotatably connected to the first vehicle logo carrier and the second vehicle logo carrier (the number of the transmission output arms 2043 can be four, which are respectively arranged at the four end points of the rectangular transmission plate 2041, and extend laterally at the corresponding end points in the direction away from the transmission plate 2041. The protruding end of the transmission output arm 2043 can also be provided with a rotating shaft for connecting with the corresponding vehicle logo carrier. The rotating shaft here can be set to be detachably connected to the transmission output arm 2043 for easy assembly).

[0036] See also Figure 5 In this embodiment, the first vehicle logo carrier and the second vehicle logo carrier are both vehicle logo carrier platforms 3. The vehicle logo carrier platform 3 is provided with at least one downwardly extending sliding extension arm 301, the sliding extension arm 301 has at least one sliding end 3012 and a driving end 3011, the sliding end 3012 is configured to be slidably connected to the track guide part 4, and the driving end 3011 is configured to be rotatably connected to the transmission output end. Among them, the sliding end 3012 is lower than the driving end 3011 in the vertical direction, and the driving end 3011 is arranged between the sliding end 3012 and the vehicle logo carrier platform 3, so that the height space required for the swing of the intermediate transmission plate 2041 can utilize the height difference between the sliding end 3012 and the vehicle logo carrier platform 3, that is, make full use of this part of the height space, so that the space required by the vehicle logo switching device as a whole in the height direction can be further compressed.

[0037] Specifically, the number of sliding extension arms 301 on each vehicle logo bearing platform 3 can be two, which are arranged at the two ends of the vehicle logo bearing platform 3 in the longitudinal direction, and correspond to the first track plate 401 and the second track plate 402 respectively. The number of sliding ends 3012 on each sliding extension arm 301 can be two, which are arranged at the two ends of the sliding extension arm 301 in the transverse direction, wherein the sliding end 3012 can be specifically a pulley for extending into and slidingly connected to the corresponding track groove (the pulley can specifically include a connecting shaft connected to the sliding extension arm 301 and a bearing installed on the connecting shaft, and the outer ring surface of the bearing is slidably connected to the corresponding track groove). The number of driving ends 3011 on each sliding extension arm 301 can be one, located between the two sliding ends 3012, and the driving end 3011 can be specifically a shaft hole opened on the sliding extension arm 301, which is used to be rotatably connected to the shaft on the transmission output arm 2043.

[0038] With the development of new energy vehicles, higher and higher requirements are put forward for the integration and miniaturization of the internal components of the automobile, especially the space of the front trunk position where the logo of the new energy vehicle is placed is even more precious, and due to the characteristics of the front layout of the new energy vehicle, the vertical space of the front is small, so the vertical height of the logo switching device is put forward. In this embodiment, the design of the logo switching motion trajectory is combined with the specific structural design to fully compress the vertical height of the logo switching device, thereby meeting the development needs of component miniaturization. In addition, the two logos corresponding to the logo switching device are usually an ordinary logo and a more expensive special logo. The logo switching device of this embodiment is switched by horizontal reciprocating. Compared with the existing lifting and lowering switching method, the switching path is short and simple, that is, the switching speed can be greatly improved, and then when the precious special logo on display is touched or damaged by humans (which can be detected by setting a pressure sensor or other sensing structure), it can be automatically and quickly switched to replace it with an ordinary logo, thereby protecting the precious special logo.

[0039] Embodiment 2 This embodiment provides a control method based on the above embodiment 1, as follows: like Figure 8 As shown, the present invention provides a vehicle logo switching device, including an MCU module and a current acquisition module, a motor transmission mechanism (i.e., the above-mentioned drive unit), a sensor module, and a power supply module electrically connected to the MCU module respectively. The MCU module integrates a state detection unit, a drive unit and a current detection unit, and is used to obtain a target sensor signal, trigger a target control instruction according to the target sensor signal, drive the motor transmission mechanism to operate the main vehicle logo and the auxiliary vehicle logo to switch between each other, and at the same time, respectively perform state detection and current detection and correction on the real-time state and real-time current during the vehicle logo switching process; wherein, the microcontroller internally integrates state detection, H-bridge drive, and current detection functions, completes state detection of the pressure sensor, recovery switch, and position switch, and realizes the drive of the H-bridge and motor current detection; the current detection unit is used to detect the current size of the motor, and when the detected current value exceeds a certain limit, the operation of the motor is stopped, thereby protecting the circuit.

[0040] The current acquisition module is connected to the current detection unit and is used to collect the real-time current signal generated during the vehicle logo switching process and feed it back to the MCU module; The motor transmission mechanism is configured as an actuator that drives the main vehicle logo and the auxiliary vehicle logo to switch between each other through the motor drive module, and is used to execute the switching action between the main vehicle logo and the auxiliary vehicle logo according to the target control instruction and feed back the switching state to the MCU module; wherein the motor transmission mechanism controls the conduction direction and conduction rate of the H bridge, thereby realizing the forward or reverse operation of the motor, and controlling the motor operation rate; The sensor modules are respectively arranged on the main vehicle logo and the auxiliary vehicle logo (they can be respectively arranged on the first vehicle logo carrier, the second vehicle logo carrier or the vehicle logos corresponding to the two vehicle logo carriers), and are used to obtain the sensor signal in real time and transmit it to the MCU module; it can be a pressure sensor / touch sensor, which is integrated into the main vehicle logo LOGO. When a hand touch signal is detected on the main vehicle logo LOGO, the drive motor works and switches to the spare or auxiliary vehicle logo LOGO.

[0041] The power supply module has one path connected to the driving module and the current acquisition module to the current detection unit, and another path directly connected to the MCU module, and is used to convert the input vehicle body power supply voltage into a digital power supply voltage and supply power to each module; wherein the status detection is a sensor signal or switch command that meets the vehicle logo switching trigger condition.

[0042] The vehicle logo switching device provided in this embodiment integrates status detection, drive and current detection functions through the MCU module, simplifies the circuit and improves the reliability of the device; the current is monitored in real time by the current acquisition module to ensure the safety of the motor; the sensor module ensures that the vehicle logo is accurately switched; the status detection unit responds to the trigger condition in time to prevent misoperation; the power supply module provides stable voltage to ensure the normal operation of the device and optimize the use of electricity; the sensor signal is quickly responded to to achieve accurate switching between the main and auxiliary vehicle logos, and the current is monitored in real time, which helps to detect and deal with abnormal situations in time and ensure continuous operation of the device. The flat design saves space and is convenient for integrating the control device into the limited space of the vehicle.

[0043] Specifically, the motor drive module includes a motor and an H-bridge composed of a first MOS tube Q1, a second MOS tube Q2, a third MOS tube Q3 and a fourth MOS tube Q4, which provide the motor with forward or reverse operation, speed control and energy support, one end of the motor is connected to the collector of the first MOS tube Q1 and the fourth MOS tube Q4, and the other end of the motor is connected to the collector of the second MOS tube Q2 and the third MOS tube Q3, and different operating states of the motor are achieved by controlling the conduction and cutoff of the four MOS tubes. The H-bridge can also be composed of four switching elements such as triodes, MOSFETs, etc. The motor is connected to the output end of the H-bridge, that is, connected between two diagonal switching elements, and different operating states of the motor are achieved by controlling the conduction and cutoff of the four switching elements. Taking a DC motor as an example, when Q1 and Q4 are turned on and Q2 and Q3 are turned off, the current returns from the positive pole of the power supply through Q1, the motor, and Q4 to the negative pole of the power supply, and the motor rotates forward; when Q2 and Q3 are turned on and Q1 and Q4 are turned off, the current returns from the positive pole of the power supply through Q2, the motor, and Q3 to the negative pole of the power supply, and the motor reverses. This can achieve forward and reverse rotation and speed adjustment of the motor to meet the needs of different working conditions. Switching elements such as MOSFET or triodes have the characteristics of low conduction voltage drop and high switching frequency, which improves the driving efficiency of the motor. The H-bridge circuit has a simple structure, stable operation, and reduced failure rate. Compared with other complex motor drive solutions, the H-bridge circuit has a low cost and is convenient for large-scale application.

[0044] Specifically, the power supply module includes a body power supply, an anti-reverse filtering module and a power management module. The output end of the body power supply is connected to the input end of the anti-reverse filtering module. One output end of the anti-reverse filtering module and the input end of the power management module are connected to the MCU module. Another output end of the anti-reverse filtering module is connected to the input end of the driving module. The output end of the driving module is connected to the input end of the current acquisition module. The output end of the current acquisition module is grounded and is used to output the original power from the body power supply, output the pre-processed power after the anti-reverse, filtering and overvoltage protection processing of the anti-reverse filtering module, and convert the input pre-processed power supply voltage into a target digital power supply voltage through the power supply module, and distribute the target digital power supply voltage to the next-level H-bridge and MCU module for power supply.

[0045] Specifically, the vehicle logo switching device provided in this embodiment further includes a position switch and a recovery switch; The position switch is used to set the preset extreme position of the main logo and the auxiliary logo corresponding to the travel, and is used to detect whether the corresponding logo has reached the target switching position. When the main / auxiliary logo runs to the preset extreme position, the position switch is triggered and the motor stops running. The preset extreme position is the end position that can be run under the switching travel; The recovery switch is integrated in the vehicle cab. When the recovery switch is turned on and the position switch is detected to be triggered at the same time, the main vehicle logo returns to the starting position; In order to achieve fast switching and reduce the time and steps required for switching, the main vehicle logo and the auxiliary vehicle logo are arranged to be linked with each other so that the switching stroke has the vehicle logo switching states of AB stroke node linkage and BC stroke node linkage. In the first state, the target control instruction is received to drive the main vehicle logo to run from the starting B stroke node to the C stroke node to recover the main vehicle logo, and the auxiliary vehicle logo runs from the A stroke node to the B stroke node to display the auxiliary vehicle logo; in the second state, the recovery instruction is received to drive the main vehicle logo to run from the C stroke node to the B stroke node to display the main vehicle logo, and the auxiliary vehicle logo runs from the B stroke node to the A stroke node to recover the auxiliary vehicle logo, and the A stroke node is the auxiliary vehicle logo in the non-switching mode. The A-stroke node is the starting position of the main logo in non-switching mode and the target position of the secondary logo in switching mode, and is located in the center display area of ​​the vehicle, that is, the logo is exposed; the C-stroke node is the target position when the main logo is recovered in switching mode, and is located in the logo recovery area, that is, hidden. The linkage setting ensures the synchronization of the main and secondary logos during the switching process, avoids potential problems or errors caused by asynchrony, and achieves fast switching response efficiency when the logo is touched by external force, realizing efficient and stable logo switching function, which not only improves switching efficiency and system stability, but also optimizes user experience, making the logo switching process smoother and more natural. Fig. 9 As shown, the above settings also ensure that the car logo can accurately reach the target position during the switching process, thereby improving the accuracy and reliability of the switching; the main and auxiliary car logos are linked to each other to achieve synchronous switching and recovery, thereby ensuring the integrity and continuity of the display; the recovery switch in the cab makes the operation more convenient and reduces the complexity of the operation; the car logo automatically stops when it reaches the preset position, thereby preventing overshoot or damage and improving the safety of the device; it can adapt to different display needs, and the car logo can be quickly switched and restored through simple instructions.

[0046] In order to achieve fast switching, the principle of this embodiment is: in the switching mode, when the pressure sensor / touch sensor is triggered by external pressure or by the change of the touch state of the vehicle logo surface, the sensing signal is obtained and fed back to the MCU module, and the target control instruction is issued by the MCU module to drive the motor transmission mechanism, and the main vehicle logo located in the central display area of ​​the vehicle is recovered and the secondary vehicle logo is simultaneously displayed in the central display area of ​​the vehicle to achieve the fast switching of the main and secondary vehicle logos; when implemented, one method uses a capacitive touch sensor: when a conductor such as a human finger approaches or touches the surface of the vehicle logo, the electric field distribution between the electrodes inside the sensor will change, thereby causing a change in the capacitance value. If the capacitance value is detected to have a significant change and exceeds the set threshold, it can be judged as a touch operation, thereby triggering the vehicle logo switching instruction. Another method uses a resistive pressure sensor: using a Wheatstone bridge circuit structure, when external pressure acts on the elastic diaphragm of the sensor, the resistance of the strain resistor will change, resulting in an imbalance of the Wheatstone bridge, and the output voltage signal will change accordingly. By measuring the change in the output voltage signal, when the change reaches the set standard, it can be judged that pressure has been detected, thereby determining that external pressure has been received and triggering the corresponding instruction. One method uses pressure-sensitive touch technology: combining a pressure sensor with a touch sensor. When a user touches the car logo, the touch action is first detected by a capacitive sensor, and then the touch force is detected by a pressure sensor. If the force reaches a preset threshold, the car logo switching command is triggered. This technology can provide more accurate operational feedback, avoid false triggering, and achieve rapid switching within 0.5 seconds.

[0047] In this embodiment, judging whether the pressure sensor / touch sensor is triggered due to external pressure or a change in the touch state of the vehicle logo surface is a process that comprehensively considers many factors, which are specifically described as follows: Setting threshold judgment: Setting appropriate thresholds for the pressure sensor and touch sensor respectively. For the pressure sensor, when the detected pressure value exceeds the set pressure threshold, it is determined that effective external pressure has been received; for the touch sensor, when the detected signal strength, touch area and other parameters exceed the set touch threshold, it is determined that a touch operation has occurred. These thresholds are usually debugged and determined according to the actual application environment and requirements. For example, when artificial external force is applied to determine a suitable touch signal strength threshold, only when the touch signal strength is higher than the threshold will it be considered a valid touch operation, and then the door opening and other instructions will be executed, while non-artificial external forces such as branches and stones are regarded as invalid touch operations.

[0048] Time characteristic judgment: The time characteristic of the signal is considered for judgment. For example, a short, instantaneous pressure change or touch signal may be an interference signal and will not be responded to; while a pressure or touch signal that lasts for a certain period of time is considered to be a valid operation instruction. The judgment of the time characteristic of the signal can be achieved by setting a time window or using a filtering algorithm. For example, during driving, if the surface of the car logo is only touched briefly, the device may ignore the signal; but if the touch time exceeds a certain duration, such as more than 0.5 seconds, the device will determine it as a valid car logo switching instruction.

[0049] Signal change rate judgment: Calculate the change rate of the pressure or touch signal to determine whether it is a real operation. If the signal change rate is within a certain range and conforms to the logic of normal operation, it is considered to be a valid instruction; if the signal change rate is abnormal, it may be interference or misoperation. For example, when a finger quickly passes over the surface of the car logo, the change rate of the touch signal will be large. In this case, the car logo switching instruction may not be triggered. Only when the finger stably touches the car logo, the signal change rate is small and stable, will it be regarded as a valid switching operation. The above method can improve the reliability and accuracy of the device by reasonably setting the threshold, analyzing the signal characteristics, and combining the vehicle status and environmental factors for judgment, providing users with a more convenient and safer use experience.

[0050] In the detection mode, the real-time status during the logo switching process is detected. When the pressure sensor / touch sensor is triggered by external pressure or the touch state change on the logo surface, the touch shutdown command corresponding to the current pressure sensor / touch sensor is identified to effectively prevent false triggering; the real-time current during the logo switching process is detected to determine whether the real-time current value has abnormal fluctuations during operation to ensure the safety of the motor operation and identify abnormalities when the current floats to prevent foreign objects such as stones from jamming the motor; in the abnormal mode, the fault handling mechanism is triggered according to the identified fault signal. When the false alarm touch signal or the pressure signal of the external force does not reach the preset intensity threshold to form a false touch signal, the corresponding pressure sensor / touch sensor is diagnosed and calibrated through the MCU module; when a stall state other than a false touch signal is identified, a stop command is issued to the motor and the corresponding protection operation is performed. After the stall fault is eliminated, a reset operation is performed to restore the normal working state, and software and hardware self-checks are automatically performed to optimize the running state. For example, if the motor fails, such as overheating, abnormal speed or failure to start, the MCU module will try to perform protective operations on the motor according to the preset algorithm and logic, such as reducing the power output of the motor, adjusting the operating parameters of the motor or trying to restart the motor, etc. If these measures cannot solve the problem, the device will record detailed fault information and display the corresponding fault prompt to the driver through the vehicle's dashboard or central control screen. At the same time, it may limit the further switching operation of the car logo to prevent the fault from further expanding. When the sensor fails, such as the touch sensor keeps misreporting the touch signal or the pressure sensor cannot correctly detect the pressure change, the MCU module will diagnose and calibrate the sensor, try to compensate for the sensor error through the software algorithm or switch to a spare sensor. When receiving a switching anomaly caused by external interference, such as severe vibration during vehicle driving, electromagnetic interference, etc., which affects the normal switching of the car logo, the device will temporarily suspend the switching operation and wait for the interference source to disappear. At the same time, the MCU module will check and correct its own program running status and clear the erroneous data or status caused by interference. Once the interference disappears and the device returns to normal, the logo switching operation will continue. If the interference lasts too long or the interference intensity is too strong, the device will send a warning message to the driver to inform him that there is an abnormality in the current logo switching.

[0051] Based on the same inventive concept, this embodiment also provides a vehicle, including the vehicle logo switching device as described in the above embodiment.

[0052] Based on the same inventive concept, see Fig.10 As shown, this embodiment also provides a control method of the vehicle logo switching device described in the above embodiment, including: Power on and read the calibration data in the current running state. The calibration data includes the starting position, target position and key parameters of the vehicle logo during the switching process. The main logo and the secondary logo are reset to zero to ensure that the logo is at the calibrated starting position before the switching action. For example, the starting position of the main logo is the B travel node, that is, located at the center of the vehicle center display area, and the starting position of the secondary coordinate is the A travel node, that is, the leftmost travel position. When switching, the main logo is moved from the B travel node to the C travel node, that is, the rightmost travel position, and the secondary logo is linked to move from the A travel node, that is, the leftmost travel position, to the B travel node to reach the display area. By returning the main logo and the secondary logo to zero, the system ensures that each switching is performed under the same initial conditions, thereby improving the accuracy of the switching; Receive target control instructions and determine whether to trigger the pressure sensor / touch sensor; When the pressure sensor / touch sensor is triggered by external pressure or by changes in the touch state of the vehicle logo surface, the pressure sensor / touch sensor is triggered, and the touch-to-shutdown command corresponding to the current pressure sensor / touch sensor is valid; the touch-to-shutdown command here refers to an internal instruction or signal triggered by external input such as pressure or touch, which is used to control the vehicle logo switching operation.

[0053] When the current shutdown command is valid, execute the main logo shutdown command, run the motor to drive the main logo to switch, record the travel information of the main logo from the starting position to the target position and read the real-time current data; Determine whether the current switching stroke exceeds the preset extreme stroke to prevent over-travel operation and ensure that the vehicle logo has been completely switched to the target position; only when the vehicle logo runs to a position exceeding the extreme stroke can it be ensured that the vehicle logo has been completely switched to the target state. If the current running stroke is less than or equal to the extreme stroke, the vehicle logo may not be completely switched, affecting the use effect and safety.

[0054] When the current switching stroke exceeds the preset extreme stroke, the logo switch in the cab successfully completes the switching operation between the main logo and the auxiliary logo, clears the touch-off command corresponding to the pressure sensor / touch sensor, shuts down the motor and puts it into standby mode. The above control method automatically reads the calibration data and judges the trigger conditions, realizes the intelligent control of the logo switching, ensures that the logo is in the starting position before switching, improves the switching accuracy, records the stroke information and real-time current data, facilitates the monitoring of the logo switching process, prevents over-travel operation, ensures that the logo is completely switched to the target state, avoids damage, clears the touch-off command and puts the motor into standby mode, and improves the stability and reliability of the device. Among them, the current switching stroke refers to the route corresponding to the main vehicle logo from the B stroke node to the C stroke node and the auxiliary vehicle logo from the A stroke node to the B stroke node. The preset extreme stroke refers to the extreme position or maximum stroke range that the vehicle logo can reach during the switching process. By comparing the current running stroke with the extreme stroke, it is possible to accurately determine whether the vehicle logo has reached the target position. If the current running stroke is less than the extreme stroke, the device may misjudge that the vehicle logo has been switched, thereby stopping the operation of the drive module, resulting in incomplete switching of the vehicle logo.

[0055] It can be understood that the above control process reads the calibration data under the current running state by powering on, and resets the main logo and the auxiliary logo to zero, ensuring that the logo is in the predetermined starting position before each switch, which improves the accuracy and consistency of the logo switching; it can automatically receive the target control command, and intelligently execute the logo switching operation according to the triggering of the pressure sensor or the touch sensor. This automatic control reduces human intervention and improves the intelligence level of the system; during the switching process, the system records the stroke information and real-time current data of the main logo. This helps to monitor the logo switching process, ensure the smooth switching action, and perform fault diagnosis when necessary; by judging whether the current switching stroke exceeds the preset extreme stroke, the system can ensure that the logo has been completely switched to the target position to prevent damage to the logo or incomplete switching due to over-travel operation; clearing the touch shutdown command and putting the motor into standby mode helps protect the system from unnecessary energy consumption and wear, while improving the stability and reliability of the system.

[0056] Further, the determining whether to trigger the pressure sensor / touch sensor includes: If the pressure sensor / touch sensor is triggered, the shutdown command of the pressure sensor / touch sensor is effective, and the main logo shutdown command is executed through the logo switch in the cab, and the motor drives the main and auxiliary logos to switch, and the travel information of the main and auxiliary logos from the starting position to the target position is recorded and the real-time current data is read; If the pressure sensor / touch sensor is not triggered, it is further determined whether the received main logo closing command is a command issued by the logo switch in the cab to prevent false triggering; If the command is issued by the Logo switch in the cab, the motor is also operated to switch the main and auxiliary logos; if the command is not issued by the Logo switch in the cab, the pressure sensor touch shutdown command is checked again to see if it is valid. If it is valid, the motor is operated to switch the main and auxiliary logos. If it is invalid, it returns to the superior to continue waiting to receive the target control command and repeat the subsequent judgment logic. This effectively distinguishes the triggering of the pressure sensor / touch sensor and the command of the Logo switch in the cab, avoids misoperation, ensures that only valid commands will execute the logo switching, enhances the stability of the device, and realizes accurate monitoring of the logo switching process by recording travel information and real-time current data. It can make corresponding judgments and processing according to different situations, and improves the intelligence level of the device. The command issued by the Logo switch in the cab here refers to the logo switching command actively triggered by the driver or vehicle control system in the cab. This command is issued through a physical switch, a touch screen interface or other electronic control methods. By effectively distinguishing between the triggering of the pressure sensor / touch sensor and the command of the logo switch in the cab, misoperation is avoided, ensuring that only valid instructions will execute the logo switching, thereby enhancing the stability and reliability of the device; it can make corresponding judgments and processing according to different situations such as the triggering of the pressure sensor / touch sensor or the command of the logo switch in the cab, thereby improving the intelligence level of the device; by recording travel information and real-time current data, it can achieve accurate monitoring of the logo switching process, which helps to promptly discover and solve potential problems and ensure the smooth switching of the logo; it can further determine whether the received main logo closing command is a command issued by the logo switch in the cab to prevent mistriggers and improve the fault tolerance of the device.

[0057] Further, the determining whether the current switching stroke exceeds the preset extreme stroke includes: When the current switching stroke does not exceed the preset extreme stroke distance, the real-time current value obtained during the switching stroke is compared with the preset stall current value to determine whether the motor is in a stall state; If the current real-time current value is greater than the preset stall current value, the motor is in stall state and the fault diagnosis process is started; Further confirm whether the current stall state is a fault. If it is confirmed that the current stall state is a fault, the motor stops and reports the relevant fault information to the ECU, i.e. the Electronic Control Unit, which is the electronic control unit. Then, the pressure sensor triggers the shutdown command and enters the standby state. If it is confirmed that there is no fault or the current current is less than the preset stall current value, it will return to the upper level to continue waiting for receiving the target control command and repeat the subsequent judgment logic; Among them, the faults confirmed as stalled status include stalls caused by over-voltage, under-voltage, over-current, abnormal temperature, foreign objects in the switching stroke, and internal faults. The above judgment process monitors the motor status in real time, promptly discovers potential problems such as stalls, and prevents more serious faults from occurring. Once a fault is confirmed, the machine is shut down immediately and reported to the ECU to avoid equipment damage or safety accidents. The cause of the fault is accurately determined to reduce misjudgments and unnecessary shutdowns, thereby improving the reliability of the device. It is convenient for maintenance personnel to quickly locate and solve problems, thereby reducing maintenance costs.
