Description

Technical Field

[0001] The present application relates to the field of intelligent parking technology, and in particular to a flat floor lock device and a control method thereof. Background Art

[0002] With the development of intelligence, parking lots have also begun to adopt intelligent billing methods. Intelligent billing can be achieved through parking lot ground locks with detection technology. When a vehicle is detected entering the parking space, the time starts, and the ground lock locks the vehicle in the parking space. When you need to leave, the time stops and charges are made according to the time. After the payment is completed, the ground lock is unlocked to allow the vehicle to leave the parking space.

[0003] Parking lot locks in the prior art usually use geomagnetic, infrared or radar detection technology to sense whether a vehicle has entered a parking space. The above three detection technologies have their own advantages and disadvantages. For example, geomagnetic technology is easily interfered by surrounding magnetic objects, resulting in inaccurate detection data, but it can effectively exclude non-magnetic objects; infrared technology will fail when the vehicle is not parked correctly according to the standard and when the infrared receiving device is exposed to sunlight, resulting in an inability to accurately detect whether the vehicle is parked, but it can work normally in rainy weather; radar technology is easily affected by rainy weather and fails, but it will not be affected by sunlight. Using a single detection technology will result in low detection accuracy of the parking lot lock, which cannot be applied to different scenarios, resulting in an inability to accurately lock the vehicle or inaccurate billing. Summary of the invention

[0004] The purpose of the present application is to provide a flat-plate ground lock device and a control method thereof to improve the accuracy of ground lock detection.

[0005] In the first aspect, the present application provides a flat floor lock device that adopts the following technical solution: A flat floor lock device comprises a controller, a baffle, a driving mechanism and a detection mechanism, wherein the driving mechanism and the detection mechanism are respectively connected to the controller for communication, the driving mechanism is located on one side of the baffle, and the driving mechanism is used to drive the baffle to rise and fall; The detection mechanism is located on the other side of the baffle, and the detection mechanism includes a geomagnetic detection device, an infrared detection device and a radar detection device. The geomagnetic detection device is used to detect changes in the magnetic field. The infrared detection device includes an infrared transmitting end and an infrared receiving end. The radar detection device includes a radar transmitting end and a radar receiving end. When the geomagnetic detection device detects a change in the magnetic field, the controller controls the infrared transmitting end to emit infrared rays, and controls the radar transmitting end to emit electromagnetic waves; When the infrared receiving end receives the reflected infrared rays or the radar receiving end receives the echoed electromagnetic waves, the controller controls the driving mechanism to drive the baffle to rise.

[0006] By adopting the above technical scheme, the present application combines the detection technologies of geomagnetism, infrared and radar. When a vehicle enters the detection range of the geomagnetic detection device, the magnetic field changes, and the geomagnetic detection device senses that a vehicle is approaching. At this time, the infrared detection color plate and the radar detection device are controlled to start working and detecting. The infrared detection device detects the vehicle by emitting infrared rays. If there is a vehicle blocking the infrared emission direction, the infrared rays will be reflected to the infrared receiving end. If there is no vehicle blocking, the infrared receiving end cannot receive the infrared reflection. The radar detection device detects the vehicle by emitting electromagnetic waves. When there is a vehicle blocking the electromagnetic wave emission direction, the electromagnetic wave will be blocked and an echo will be generated. The radar receiving end detects the echo to determine whether there is a vehicle. If there is no vehicle blocking, the radar receiving end cannot receive the electromagnetic wave echo. The present application uses the three technical detection means of geomagnetism, infrared and radar to complement each other and work together to reduce the influence of the outside world on the ground lock device. It can be used normally in both sunlight and rainy environments, effectively improving the accuracy of ground lock detection. At the same time, the geomagnetic detection device of the present application will trigger the infrared detection device and the radar detection device to work only when a change in the magnetic field is detected. This working mode is more energy-efficient than the common periodic uninterrupted detection, and can improve the durability of the ground lock device.

[0007] Furthermore, the driving mechanism includes a housing, a driving motor, a gearbox and a driving battery, wherein the driving motor, the gearbox and the driving battery are installed in the housing, the gearbox is connected to the output shaft of the driving motor, the gearbox output shaft is connected to the baffle, and the driving battery is connected to the power supply end of the driving motor.

[0008] By adopting the above technical solution, the present application drives the baffle to rise and fall through a driving mechanism, and the gearbox is used to decelerate the driving motor to ensure the stability of the baffle lifting process.

[0009] Furthermore, the gearbox output shaft is provided with an angle sensor, and the angle sensor is used to detect the angle of the baffle lifting and lowering.

[0010] Most parking lot locks in the prior art use travel switches and magnetic encoding methods to detect angles. The travel switch has poor detection accuracy and can only detect approximate angles, resulting in large errors in angle detection results. Although the magnetic encoding detection method is more accurate than the travel switch, it still has large errors and is complex to install. By adopting the above technical solution, the present application detects the lifting angle of the baffle through an angle sensor. The angle sensor only needs to be installed on the output shaft of the gearbox to detect the angle. It is easy to install and the detection accuracy can be as accurate as 0.1 degrees, effectively reducing the error of the lifting angle control.

[0011] Furthermore, the driving mechanism also includes a solar panel, which is installed on the upper surface of the shell, and the output end of the solar panel is connected to the charging end of the driving battery. The solar panel is used to convert solar energy into electrical energy to charge the driving battery.

[0012] By adopting the above technical solution, the present application charges the driving battery through the solar panel, which can effectively save energy. At the same time, it can be continuously charged while in use, thereby improving the endurance of the ground lock device.

[0013] Furthermore, a groove is formed on one side of the baffle away from the output shaft of the driving motor, and a plurality of rollers are arranged in the groove.

[0014] By adopting the above technical solution, the present application arranges a roller at one end where the baffle rises, thereby ensuring that the bottom of the vehicle can be effectively protected from being scratched after the baffle rises.

[0015] Furthermore, it also includes a voice broadcast device, which is communicatively connected to the controller.

[0016] By adopting the above technical solution, the present application uses a voice broadcast device to broadcast the current status of the ground lock device, thereby improving the user experience and making management easier.

[0017] In the second aspect, a flat floor lock device control method provided by the present application adopts the following technical solution: A control method for a flat-plate ground lock device is applied to a flat-plate ground lock device according to the first aspect, and includes a lock raising process, specifically including: When the geomagnetic detection device detects a change in the magnetic field, the geomagnetic detection device sends a geomagnetic detection signal to the controller; When the controller receives the geomagnetic detection signal, the controller controls the infrared transmitting end to emit infrared rays, and controls the radar transmitting end to emit electromagnetic waves; When the infrared receiving end receives the reflected infrared rays, the infrared detection device sends an infrared detection signal to the controller; When the radar receiving end receives the echoed electromagnetic wave, the radar detection device sends a radar detection signal to the controller; When the controller receives an infrared detection signal or a radar detection signal, the controller controls the driving mechanism to drive the baffle to rise to a preset locking angle.

[0018] By adopting the above technical solution, this application combines the detection technologies of geomagnetism, infrared and radar. The three technical detection methods complement each other and work together to reduce the impact of the outside world on the ground lock device. It can be used normally in both sunlight and rainy environments, effectively improving the accuracy of ground lock detection. At the same time, since the geomagnetic detection equipment will trigger the infrared detection equipment and radar detection equipment to work only when it detects a change in the magnetic field, this working mode is more energy-efficient than the common periodic uninterrupted detection, and can improve the durability of the ground lock device.

[0019] Furthermore, the controller controls the driving mechanism to drive the baffle to rise to a preset locking angle, specifically including: When the baffle encounters an obstacle while rising to a preset angle, the controller obtains the current real-time rising angle; When the current real-time rising angle is greater than 35 degrees, it is determined that the current baffle has reached the actual locking angle, and the controller controls the baffle to descend to the preset protection angle; When the current real-time rising angle is greater than 25 degrees and less than 35 degrees, it is determined that the current baffle has not reached the actual locking angle, and the controller controls the baffle to rise again after a preset protection time until the baffle rises to the preset locking angle or the actual locking angle; When the current real-time rising angle is less than 25 degrees, the controller generates an abnormal locking signal and controls the baffle to drop to the preset protection angle. The controller controls the baffle to rise again after the preset protection time until the baffle rises to the preset locking angle or the actual locking angle.

[0020] By adopting the above technical solution, the present application ensures that the baffle can smoothly rise to the preset locking angle by monitoring the angle of the baffle in real time during the rising process. When encountering an obstacle during the rising process to the preset angle, the cause of the current obstacle is determined according to the actual rising angle, and adaptive adjustment is performed to effectively protect the safety of the ground locking device and the vehicle.

[0021] Furthermore, the controller controls the baffle to rise again after a preset protection time, until the baffle rises to a preset locking angle or an actual locking angle, specifically including: The controller controls the baffle to rise, and the controller obtains the current real-time rising angle; When the real-time ascent angle is greater than 35 degrees, the controller cancels the abnormal vehicle locking signal and reports the normal vehicle locking information; When the real-time ascent angle is less than 35 degrees, the controller reports abnormal vehicle locking information.

[0022] By adopting the above technical solution, this application reports normal or abnormal vehicle locking information so that management personnel can be informed of the current situation in a timely manner, which facilitates unified management.

[0023] Furthermore, the lock-down process is also included, including: The controller controls the driving mechanism to drive the baffle to rise to a preset locking angle, and after the preset free parking time has passed, the timing starts; After receiving the payment request signal, the controller stops timing and obtains the total parking time; The controller obtains the parking fee according to the preset parking unit price and the total parking time, and generates a payment signal according to the parking fee; After receiving the payment success signal, the controller controls the driving mechanism to drive the baffle to descend to the ground.

[0024] By adopting the above technical solution, the present application performs the locking process of the ground lock by receiving the payment request signal sent by the user, thereby ensuring the stability of the ground lock lowering process and improving the accuracy of the parking fee calculation.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. This application uses the three technical detection methods of geomagnetism, infrared and radar to complement each other and work together to reduce the impact of the outside world on the ground lock device. It can be used normally in both sunlight and rainy environments, effectively improving the accuracy of ground lock detection; 2.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0028] Parking lot locks in the prior art usually use geomagnetic, infrared or radar detection technology to sense whether a vehicle has entered a parking space. The above three detection technologies have their own advantages and disadvantages. For example, geomagnetic technology is easily interfered by surrounding magnetic objects, resulting in inaccurate detection data, but it can effectively exclude non-magnetic objects; infrared technology will fail when the vehicle is not parked correctly according to the standard and when the infrared receiving device is exposed to sunlight, resulting in an inability to accurately detect whether the vehicle is parked, but it can work normally in rainy weather; radar technology is easily affected by rainy weather and fails, but it will not be affected by sunlight. Using a single detection technology will result in low detection accuracy of the parking lot lock, which cannot be applied to different scenarios, resulting in an inability to accurately lock the vehicle or inaccurate billing. Therefore, an embodiment of the present application provides a flat-plate lock device, with reference to Figure 1 , including a controller 1, a baffle 2, a driving mechanism 3 and a detection mechanism 4, the driving mechanism 3 and the detection mechanism 4 are respectively connected to the controller 1 for communication, the driving mechanism 3 is located on one side of the baffle 2, and the driving mechanism 3 is used to drive the baffle 2 to rise and fall. The detection mechanism 4 is located on the other side of the baffle 2, and the detection mechanism 4 is used to detect whether the vehicle enters or leaves the detection range. The detection mechanism 4 includes a geomagnetic detection device 41, an infrared detection device 42 and a radar detection device 43, the geomagnetic detection device 41 is used to detect changes in the magnetic field, the infrared detection device 42 includes an infrared transmitting end and an infrared receiving end, and the radar detection device 43 includes a radar transmitting end and a radar receiving end. In the specific implementation process, when the geomagnetic detection device 41 detects changes in the magnetic field, the controller 1 controls the infrared transmitting end to emit infrared rays, and controls the radar transmitting end to emit electromagnetic waves. When the infrared receiving end receives the reflected infrared rays or the radar receiving end receives the echoed electromagnetic waves, the controller 1 controls the driving mechanism 3 to drive the baffle 2 to rise.

[0029] The implementation principle of the embodiment of the present application is as follows: the present application combines the detection technologies of geomagnetism, infrared and radar. When a vehicle enters the detection range of the geomagnetic detection device 41, the magnetic field changes, and the geomagnetic detection device 41 senses that a vehicle is approaching. At this time, the infrared detection color plate and the radar detection device 43 are controlled to start working and detecting. The infrared detection device 42 detects the vehicle by emitting infrared rays. If there is a vehicle blocking the infrared emission direction, the infrared rays will be reflected to the infrared receiving end. If there is no vehicle blocking, the infrared receiving end cannot receive the infrared reflection. The radar detection device 43 detects the vehicle by emitting electromagnetic waves. When there is a vehicle blocking the electromagnetic wave emission direction, the electromagnetic wave will be blocked and an echo will be generated. The radar receiving end detects the echo to determine whether there is a vehicle. If there is no vehicle blocking, the radar receiving end cannot receive the electromagnetic wave echo. The present application uses the three technical detection means of geomagnetism, infrared and radar to complement each other and work together to reduce the influence of the outside world on the ground lock device. It can be used normally in both sunlight and rainy environments, effectively improving the accuracy of ground lock detection. At the same time, the geomagnetic detection device 41 of the present application will trigger the infrared detection device 42 and the radar detection device 43 to work only when a magnetic field change is detected. This working mode is more energy-efficient than the common periodic uninterrupted detection and can improve the durability of the ground lock device.

[0030] like Figure 3 As shown, the driving mechanism 3 of the embodiment of the present application includes a housing 31, a driving motor 32, a gearbox 33 and a driving battery 34, wherein the driving motor 32, the gearbox 33 and the driving battery 34 are installed in the housing 31, the gearbox 33 is connected to the output shaft of the driving motor 32, the output shaft of the gearbox 33 is connected to the baffle 2, and the driving battery 34 is connected to the power supply end of the driving motor 32. The driving battery 34 is used to supply power to the driving motor 32, and the gearbox 33 is used to decelerate the driving motor 32, and then control the lifting and lowering of the baffle 2 by deceleration to ensure the stability of the lifting and lowering process of the baffle 2. In the specific implementation process, the housing 31 is made of a waterproof and sealed material, which is used to protect the driving motor 32, the gearbox 33 and the driving battery 34.

[0031] like Figure 1 As described, the driving mechanism 3 of the embodiment of the present application further includes a solar panel 35, which is mounted on the upper surface of the housing 31, and the output end of the solar panel 35 is connected to the charging end of the driving battery 34, and the solar panel 35 is used to convert solar energy into electrical energy to charge the driving battery 34. The power supply of the solar panel 35 can effectively save energy, and can be continuously charged while in use, thereby improving the endurance of the ground lock device.

[0032] like Figure 1As shown, in the embodiment of the present application, a groove is provided on one side of the baffle 2 away from the output shaft of the drive motor 32, and a plurality of rollers 21 are provided in the groove. In the specific implementation process, when the baffle 2 rises, the side away from the drive motor 32 will contact the bottom of the vehicle. In the embodiment of the present application, the rollers 21 are provided on the side of the baffle away from the output shaft of the drive motor 32, so that the baffle 2 can slide when contacting the bottom of the vehicle, ensuring that the bottom of the vehicle will not be scratched.

[0033] Most parking locks in the prior art use travel switches and magnetic encoding methods to detect angles. The travel switch has poor detection accuracy and can only detect approximate angles, resulting in large errors in angle detection results. Although the magnetic encoding detection method is more accurate than the travel switch, it still has large errors and is complex to install. Therefore, the output shaft of the gearbox 33 of the embodiment of the present application is also provided with an angle sensor 36, which is used to detect the angle of the baffle 2. The angle sensor 36 only needs to be installed on the output shaft of the gearbox 33 to detect the angle. It is easy to install and the detection accuracy can be as accurate as 0.1 degrees, effectively reducing the error of the lifting angle control.

[0034] In a preferred embodiment, the embodiment of the present application is further provided with a voice broadcast device 5, which is communicatively connected to the controller 1. The voice broadcast device 5 performs voice broadcasting of the current state of the ground lock device, thereby improving the user experience and making management easier.

[0035] The present application also provides a method for controlling a flat floor lock device, including a lock raising process, referring to Figure 4 , including: S1. When the geomagnetic detection device 41 detects a change in the magnetic field, the geomagnetic detection device 41 sends a geomagnetic detection signal to the controller 1.

[0036] Specifically, when the geomagnetic detection device 41 detects a change in the magnetic field, it indicates that a vehicle may have entered the detection range of the geomagnetic detection device 41, but it may also be a change in the magnetic field caused by external magnetic field interference. Therefore, the geomagnetic detection signal is first sent to the controller 1 for the next step of judgment.

[0037] S2. When the controller 1 receives the geomagnetic detection signal, the controller 1 controls the infrared transmitting end to transmit infrared rays, and controls the radar transmitting end to transmit electromagnetic waves.

[0038] Specifically, the controller 1 receives the geomagnetic detection signal, preliminarily determines that a vehicle may be driving in, and controls the infrared detection device 42 and the radar detection device 43 to start and perform the next step of judgment.

[0039] S3. When the infrared receiving end receives the reflected infrared rays, the infrared detection device 42 sends an infrared detection signal to the controller 1.

[0040] Specifically, the infrared detection device 42 detects vehicles by emitting infrared rays. If a vehicle blocks the infrared ray emission direction, the infrared ray will be reflected to the infrared receiving end. If there is no vehicle blocking the infrared receiving end, the infrared receiving end cannot receive the reflected infrared ray. Therefore, when the infrared receiving end receives the reflected infrared ray, it can be determined that a vehicle is currently entering.

[0041] S4. When the radar receiving end receives the echoed electromagnetic wave, the radar detection device 43 sends a radar detection signal to the controller 1.

[0042] Specifically, the radar detection device 43 detects vehicles by emitting electromagnetic waves. When a vehicle blocks the emission direction of the electromagnetic waves, the blocked electromagnetic waves will generate echoes. The radar receiving end detects the echoes to determine whether there is a vehicle. If there is no vehicle blocking the radar, the radar receiving end cannot receive the electromagnetic wave echo. Therefore, when the radar receiving end receives the echoed electromagnetic wave, it can be determined that a vehicle is currently entering.

[0043] S5. When the controller 1 receives an infrared detection signal or a radar detection signal, the controller 1 controls the driving mechanism 3 to drive the baffle 2 to rise to a preset vehicle locking angle.

[0044] Specifically, since the infrared detection device 42 may fail when exposed to sunlight, and the radar detection device 43 may fail in rainy weather, both are detected at the same time. As long as any one sends a detection signal to the controller 1, it can be determined when a vehicle is entering, so that the embodiment of the present application can be applied to a variety of different usage scenarios. After the controller 1 determines that a vehicle is currently entering, it controls the drive mechanism 3 to drive the baffle 2 to rise.

[0045] The embodiment of the present application is provided with an angle sensor 36 to monitor the rising angle of the baffle 2 in real time. Therefore, in step S5, the controller 1 controls the driving mechanism 3 to drive the baffle 2 to rise to a preset locking angle, which specifically includes: S51. When the baffle 2 encounters an obstacle while rising to a preset angle, the controller 1 obtains the current real-time rising angle.

[0046] Specifically, the angle sensor 36 converts the angle change generated when the output shaft of the reduction gearbox rotates into an electrical signal output through the sensor, which is used to control or monitor the angle change.

[0047] S52, when the current real-time rising angle is greater than 35 degrees, it is determined that the current baffle 2 has reached the actual vehicle locking angle, and the controller 1 controls the baffle 2 to descend to a preset protection angle.

[0048] Specifically, when the baffle 2 encounters resistance when its rising angle is greater than 35 degrees, it may be because the chassis of the current vehicle entering is low. Therefore, it is judged that it touches the bottom of the vehicle normally, and the baffle 2 is controlled to automatically descend to a preset protection angle to protect the bottom of the vehicle, and normal vehicle locking information is reported.

[0049] S53, when the current real-time rising angle is greater than 25 degrees and less than 35 degrees, it is determined that the baffle 2 has not reached the actual locking angle, and the controller 1 controls the baffle 2 to rise again after a preset protection time until the baffle 2 rises to the preset locking angle or the actual locking angle.

[0050] Specifically, if the baffle 2 encounters resistance when its rising angle is greater than 25 degrees and less than 35 degrees, it may be that the vehicle is not parked properly or there are other malfunctions. The baffle 2 will first maintain the current angle. The preset protection time is 10 seconds. Then, after 10 seconds, try to control the baffle 2 to rise again. If the rising angle is greater than 35 degrees again, report the normal vehicle locking information. If the rising angle is still less than 35 degrees, report the abnormal vehicle locking status information and maintain the current angle status.

[0051] S54, when the current real-time rising angle is less than 25 degrees, the controller 1 generates an abnormal locking signal and controls the baffle 2 to descend to a preset protection angle. The controller 1 controls the baffle 2 to rise again after a preset protection time until the baffle 2 rises to the preset locking angle or the actual locking angle.

[0052] Specifically, if the baffle 2 encounters resistance when its rising angle is less than 25 degrees, it is considered that the locking process is abnormal, and the abnormal locking status information is reported. The baffle 2 is controlled to descend to the ground for locking protection. The preset protection time is 10 seconds. Then, after 10 seconds, try to control the baffle 2 to rise again. If the rising angle is greater than 35 degrees again, the normal locking information is reported. If the rising angle is greater than 25 degrees and less than 35 degrees again, the abnormal locking information is reported and the current angle status is maintained. If the rising angle is less than 25 degrees again, the abnormal locking information is reported, and the fault status information is generated, and the baffle 2 is controlled to descend to the ground for locking protection again.

[0053] In the specific implementation process, normal vehicle locking information and abnormal vehicle locking information are reported to the management terminal of the management personnel, so that the management personnel can know the current vehicle locking situation in time, which is convenient for unified management. A voice broadcast device 5 can also be set to voice broadcast the current normal vehicle locking information or abnormal vehicle locking information, so that the user can also know the current vehicle locking situation in time.

[0054] The embodiment of the present application also includes a lock-down process, which specifically includes: A1. The controller 1 controls the driving mechanism 3 to drive the baffle 2 to rise to a preset locking angle, and after a preset free parking time has passed, the timing starts.

[0055] Specifically, assuming that the preset free parking time is 30 minutes, the parking time will start to be calculated 30 minutes after the lock-up process is completed.

[0056] A2. After receiving the payment request signal, the controller 1 stops timing and obtains the total parking time.

[0057] Specifically, when the user needs to leave the parking lot, the user sends a payment request signal to the controller 1 by scanning a code with a mobile device, etc. The controller 1 stops timing and takes the time period from the start of timing to the stop of timing as the total parking time.

[0058] A3. The controller 1 obtains the parking fee according to the preset parking unit price and the total parking time, and generates a payment signal according to the parking fee.

[0059] Specifically, the parking fee is calculated based on the preset time unit price and the total parking time, and a payment signal is generated and sent to the mobile device from which the user sends the payment request signal.

[0060] A4. After receiving the payment success signal, the controller 1 controls the driving mechanism 3 to drive the baffle 2 to descend to the ground.

[0061] Specifically, when the user receives the payment signal and completes the payment, a payment success signal is sent to the controller 1, and the controller 1 controls the baffle 2 to complete the locking process so that the vehicle can drive out. If the user has not completed the payment, the controller 1 cannot control the baffle 2 to lock, and the vehicle cannot drive out.

[0062] In the specific implementation process, the baffle 2 may also be obstructed during the descent process. The angle sensor 36 monitors the descent angle of the baffle 2 in real time. When the descent angle is greater than 35 degrees and encounters resistance, the controller 1 controls the baffle 2 to stop descending and reports abnormal lock information. The preset protection time is 10 seconds, and the baffle 2 is tried to descend again after 10 seconds. When the descent angle is less than 35 degrees and encounters resistance, it is considered that the baffle 2 currently has a risk of pinching the foot. The controller 1 controls the baffle 2 to automatically rebound about 10 degrees and reports abnormal lock information. The preset protection time is 10 seconds, and the baffle 2 is tried to descend again after 10 seconds.

[0063] After a certain period of time, the detection mechanism 4 detects whether the vehicle has left. If it is detected that the vehicle has left, the whole process is completed. If it is detected that the vehicle has not left, the controller 1 controls the baffle 2 to lock again and continue to count. If the vehicle fails to pay and tries to leave by force, the baffle 2 will be triggered to shake and alarm, and the management personnel will be informed that there is a suspicion of evading payment.

[0064] By adopting the above technical solution, the present application performs the locking process of the ground lock by receiving the payment request signal sent by the user, thereby ensuring the stability of the ground lock lowering process and improving the accuracy of the parking fee calculation.

[0065] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
