Description

Technical Field

[0001] This application relates to the field of intelligent parking technology for multi-level parking garages, and in particular to an intelligent parking method. Background Technology

[0002] The parking garage market continues to grow, and parking garage types are becoming increasingly diverse. Among them, smart parking garages employ a photoelectric detection system to monitor the car's position and shape upon entry. Only when the car's height and parking position meet the requirements can it enter the garage's work area; otherwise, collisions can easily occur when moving and storing cars within the garage.

[0003] When moving cars in a smart garage, a transfer device is typically used. Therefore, the car needs to be parked in the center of the garage transfer platform, meaning the car's centerline is aligned with the platform's centerline.

[0004] Currently, the parking method is usually as follows: when a car drives to the transition area, the front wheels need to be positioned in the corresponding positions along the length of the car, usually by using front wheel stops to fix the front wheels in the corresponding positions; in the width direction, a contact centering method is used, that is, a motor drives a push rod to push the vehicle so that the center line of the vehicle is aligned with the center line of the garage transition area, so that the transporter can smoothly transport the vehicle.

[0005] However, this method has the following shortcomings and defects: the wheels need to be parked in a fixed position, and various guiding devices and corresponding motors need to be installed in the garage transfer area, which reduces the usable space in the garage transfer area. This results in the need to adjust the position of the vehicle multiple times to park the wheels in a fixed position, increasing the number of steps for car owners to park and making parking more difficult. Summary of the Invention

[0006] Therefore, it is necessary to provide an intelligent parking method that reduces parking difficulty and improves parking comfort.

[0007] To address the aforementioned technical problems, this application provides the following technical solution:

[0008] A smart parking method, the smart parking system including a garage conversion platform, multiple centering mechanisms, a transporter, and a pressure detector; the multiple centering mechanisms are arranged on the garage conversion platform, and the pressure detector is used to detect the pressure value applied by the wheels to the centering mechanism and generate a pressure value signal; the smart parking method includes the following parking steps:

[0009] S1. The vehicle drives into the garage conversion platform, and based on the detection and pressure value signal of the pressure sensor, the wheels are adjusted to be positioned on the corresponding centering mechanism, and a parking signal is generated; S2. A parking prompt is issued according to the parking signal; S3. The vehicle is parked according to the parking prompt; S4. The pressure detector detects the pressure value of the vehicle on the centering mechanism and generates a pressure value signal; S5. The current position of each wheel is obtained based on the pressure value signal, and the position of the axial centerline of the garage conversion platform is obtained; S6. Based on the current position of each wheel and the position of the axial centerline of the garage conversion platform, the target position of each wheel, the path of each wheel, and the running time of the corresponding centering mechanism are obtained; S7. The centering mechanism adjusts the position of the wheels according to the wheel movement path so that the axial centerline of the wheel is aligned with the axial centerline of the garage conversion platform; S8. The transporter transports the vehicle into the garage for storage.

[0010] Understandably, in the parking method provided by this application, the vehicle only needs to be parked within the preset parking area to meet the parking requirements, without the wheels needing to be precisely parked in a fixed position. This reduces the vehicle's posture requirements when entering the garage transition platform, thereby reducing the difficulty for the driver to adjust the wheel position and simplifying the parking process. Furthermore, by providing timely parking status prompts, the system can provide timely feedback on parking, thus avoiding parking errors and ensuring that the vehicle is parked quickly and appropriately, effectively improving parking comfort and the intelligence of the garage.

[0011] In one embodiment, step S1 includes the following steps: detecting whether the vehicle meets the parking capacity specifications of the garage; detecting whether the vehicle is parked in place; if it does not meet the parking capacity specifications and / or is not parked in place, generating a parking incomplete signal and readjusting the vehicle position; if it meets the parking capacity specifications and is parked in place, generating a parking complete signal.

[0012] Understandably, by checking whether a vehicle meets the garage's capacity specifications, it is possible to prevent non-compliant vehicles from being parked in the garage, thereby avoiding damage to vehicles due to incompatibility with the garage. Furthermore, by checking whether the vehicle is parked properly, it is helpful to promptly remind and adjust the vehicle's parking position, reducing parking difficulties.

[0013] In one embodiment, the step "detecting whether the vehicle meets the garage's capacity specifications" includes the following steps: detecting whether the vehicle is located within a preset length range; detecting whether the vehicle is located within a preset width range; and detecting whether the vehicle is located within a preset height range.

[0014] Understandably, by detecting whether a vehicle is within a preset length, width, and height range, the system can determine whether the vehicle matches the garage's capacity specifications from multiple dimensions, thereby improving detection accuracy.

[0015] In one embodiment, detecting whether the vehicle is parked correctly includes the following steps: detecting whether the pressure value received by the centering mechanism has changed, and generating a pressure value signal accordingly; comparing whether the changed pressure value is within a preset threshold range based on the pressure value signal; if not, readjusting the vehicle position; if yes, indicating that the vehicle is parked correctly, and generating a parking signal.

[0016] In one embodiment, the pressure value received by each of the centering mechanisms is detected to be within a preset threshold range. If all of them are within the preset threshold range, it indicates that the vehicle has stopped in place. If the pressure value received by at least one of the centering mechanisms is not within the preset threshold range, the vehicle position is readjusted. Two centering mechanisms can be provided, corresponding to one front wheel and one rear wheel of the vehicle, respectively. Alternatively, four centering mechanisms can be provided, corresponding to two front wheels and two rear wheels of the vehicle, respectively.

[0017] Understandably, by setting a threshold range and comparing whether the pressure value of the centering mechanism is within that threshold range, it is possible to accurately determine whether the vehicle has stopped properly. This method of judgment is simple and quick, and can reduce the difficulty of parking.

[0018] In one embodiment, the parking signal includes a parking complete signal and a parking incomplete signal; a pressure detector is used to detect the pressure on the centering mechanism and generate a pressure value signal; the controller determines whether the parking is complete based on the pressure value signal and generates the parking signal; a prompter is used to receive the parking signal, the prompter is electrically and / or signalally connected to the controller, and the prompter issues a prompt of "parking complete or parking incomplete" after receiving the parking signal.

[0019] Understandably, the prompts can promptly remind you of the parking status, greatly reducing the difficulty of parking.

[0020] In one embodiment, the pressure values ​​at multiple points on the centering mechanism are detected, and the current wheel position is calculated based on the pressure values ​​at the multiple points.

[0021] Understandably, detecting the pressure values ​​at multiple points on the centering mechanism can help improve the accuracy of wheel position calculation.

[0022] In one embodiment, the parking method further includes the steps of: detecting the pressure value currently applied to the centering mechanism after vehicle centering and generating a pressure value signal; determining the position of the wheel after centering based on the pressure value signal and comparing it with the target position of the wheel to determine whether the vehicle is centered; if the positions are consistent, the vehicle is centered; if they are inconsistent, the centering mechanism readjusts the position of the wheel.

[0023] Understandably, by comparing the vehicle's position after alignment with the calculated target alignment position, the position of the wheels can be adjusted in a timely manner to prevent the vehicle from being parked crookedly and affecting its transport into the warehouse.

[0024] In one embodiment, the transporter includes multiple sets of clamping arms, each set of clamping arms being used to clamp a corresponding wheel; the step "the transporter transports the vehicle to the garage for storage" includes the following steps: adjusting the axial spacing between the multiple sets of clamping arms to accommodate the position of the wheel; the clamping arms clamping the corresponding wheel to transport the vehicle to the garage for storage.

[0025] Understandably, the way the transporter moves vehicles by clamping the wheels avoids wear and tear on the vehicle during clamping, and the transporter can clamp the wheels under the vehicle, so there is no need to reserve space for the transporter on the garage transfer platform, thus reducing the area occupied by the garage transfer platform.

[0026] In one embodiment, the step "adjusting the axial spacing between the multiple sets of clamping arms to adapt to the position of the wheel" includes the following steps: obtaining the wheelbase based on the current position of the wheel; and adjusting the spacing between the multiple sets of clamping arms based on the wheelbase to adapt to the position of the wheel.

[0027] It is understandable that the spacing between the clamping arms corresponds to the wheel's wheelbase, so that the clamping arms are positioned to correspond to the wheel, thus enabling accurate and stable clamping of the corresponding wheel when clamping it.

[0028] In one embodiment, the step "adjusting the spacing between multiple clamping arm groups according to the wheel wheel wheelbase" includes the following steps: determining whether the position of the wheel corresponds to the position of the clamping arm group; if they do not correspond, adjusting the position of the transporter itself and the position of the clamping arm group; if they correspond, the transporter extends the clamping arm group and clamps the corresponding wheel, transporting the vehicle to the garage for storage.

[0029] Understandably, adding a step to determine whether the position of the wheel corresponds to the position of the clamping arm assembly is beneficial for timely adjustment of the position of the transporter.

[0030] Compared to existing technologies, the parking method provided in this application only requires the vehicle to be parked within a preset parking area to meet parking requirements. It eliminates the need for the wheels to be precisely positioned in a fixed location, reducing the vehicle's posture requirements when entering the garage transfer platform. This simplifies the process for drivers to adjust wheel positions and streamlines the parking process. Furthermore, timely parking status notifications provide prompt feedback to prevent parking errors and ensure the vehicle is parked quickly and appropriately, effectively improving parking comfort and the intelligence of the garage.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0051] Please see Figures 1 to 4 One embodiment of this application provides a parking device 100, which includes a garage conversion platform 30, a centering mechanism 10, a pressure detector 20, a prompter, and a controller. The controller is electrically and / or signal-connected to the centering mechanism 10, the prompter, and the pressure detector 20. The garage conversion platform 30 serves as an intermediate support platform for temporarily parking a vehicle 200 to facilitate attitude adjustment. The centering mechanism 10 is disposed on the garage conversion platform 30 and is used to support the wheels 201 of the vehicle 200 and move the vehicle 200 to adjust its position on the garage conversion platform 30. The pressure detector 20 is used to detect the pressure value applied by the wheels 201 to the centering mechanism 10 and generate a pressure value signal. The controller is used to adjust the position of the vehicle 200 based on the pressure value. The signal acquires whether the wheel 201 is located on the centering mechanism 10 and outputs a parking in place signal or a parking not in place signal; after receiving the "parking in place signal or parking not in place signal" issued by the controller, the prompt outputs a corresponding "parking completed or parking not completed" prompt, so that the car owner can perform parking operation or adjust the position of the vehicle according to the prompt; wherein, the controller receives the pressure value data measured by the pressure detector 20, and calculates the current position and centering position of the wheel 201 based on the pressure value data, so as to calculate the path that the vehicle 200 needs to move and the running time of the centering mechanism 10, and after the parking operation command is issued, controls the centering mechanism 10 to start and drive the corresponding wheel 201 to move to the centering position, so as to adjust the center line of the vehicle 200 to align with the center line of the garage conversion platform 30.

[0052] The parking device 100 provided in this application allows the vehicle owner or parking personnel to drive the vehicle 200 onto the garage conversion platform 30, with all four wheels 201 positioned on the centering mechanism 10, and generate a parking signal. Based on the parking signal, a parking prompt is issued. After receiving the parking prompt, the vehicle owner or parking personnel complete the parking operation. At this time, no other stopping methods are needed to limit or stop the wheels. After the vehicle owner or parking personnel completes the parking operation and gets out of the vehicle, the wheels 201 apply pressure to the centering mechanism 10. The pressure detector 20 detects the change in pressure value and generates a pressure value signal. Based on the pressure value signal, the movement path of the wheels 201 and the operation of the counterweight mechanism are obtained. During the time it takes, the centering mechanism 10 moves the wheels 201 according to their movement path and running time, so that the vehicle 200 can complete the centering. This application eliminates the use of front wheel stops and contact centering methods when parking, effectively reducing the required height and width of the garage transfer platform 30, saving space on the garage transfer platform 30, eliminating protruding structures on the garage transfer platform 30, and increasing the safety and aesthetics of the garage transfer platform 30; it also reduces the vehicle body posture requirements for the vehicle 200 to enter the garage transfer platform 30, simplifies the parking steps, effectively reduces the difficulty of parking, and thus improves parking comfort and garage intelligence.

[0053] like Figure 11 As shown, the parking device 100 also includes a parking detector 4040. The parking detector 40 is used to detect whether the vehicle 200 meets the parking capacity specifications of the garage and to assist in monitoring whether the vehicle 200 is centered in the target position. If it meets the parking capacity specifications and is parked in place, the controller controls the prompt to issue a "parking completed" prompt. If it does not meet the parking capacity specifications and / or is not parked in place, the car owner continues to adjust the position of the vehicle 200 until it meets the requirements. Of course, if it does not meet the parking capacity specifications of the garage, the vehicle 200 cannot be parked on the garage conversion platform 30 and cannot be stored.

[0054] like Figures 11 to 13 As shown, the parking detector 40 includes a vehicle length sensor 42, a vehicle height sensor 41, and a vehicle width sensor 43. These sensors are used to detect whether the vehicle 200 is within a preset length range, a preset height range, and a preset width range after parking, respectively, ensuring that the vehicle 200's dimensions do not exceed the garage's capacity and preventing collisions during lifting. Additionally, the vehicle width sensor 43 can also detect whether the vehicle 200 is properly aligned after it has been aligned.

[0055] Among them, the vehicle length sensor 42, vehicle height sensor 41, and vehicle width sensor 43 are all photoelectric sensors.

[0056] The parking device 100 also includes a transporter (not shown), which is used to transport the vehicle 200 from the garage transfer platform 30 to the garage for storage. The transporter is signal-connected to the controller. After the centering mechanism 10 completes the centering of the vehicle 200, the controller controls the transporter to transport the vehicle 200 from the garage transfer platform 30 to the garage for storage. When the owner needs to retrieve the vehicle, the controller then controls the transporter to move the vehicle 200 from the garage back to the garage transfer platform 30.

[0057] Specifically, in one embodiment, the transporter includes four sets of clamping arms, each set used to clamp the wheel 201. The four sets of clamping arms work together to clamp the four wheels 201 of the vehicle 200 and transport the vehicle 200. The controller, based on the current position of the wheel, controls the transporter to adjust the distance between the two sets of clamping arms along the axial direction of the vehicle 200 according to the position of the wheel 201, so that the distance matches the wheel spacing of the vehicle 200, allowing each set of clamping arms to clamp the corresponding wheel.

[0058] like Figure 1 and Figure 3 As shown, at least two centering mechanisms 10 are provided, with the two centering mechanisms 10 being arranged opposite each other at both ends of the garage conversion platform 30 and respectively used to support the front wheels and rear wheels of the vehicle, so that when parking, the four wheels of the vehicle 200 can be parked on the centering mechanisms 10.

[0059] For example, such as Figure 1 and Figure 3 As shown, in one embodiment, four centering mechanisms 10 are provided, each positioned at one of the four corners of the garage conversion platform 30 to accommodate the four wheels of the vehicle 200. These four centering mechanisms 10 are independent of each other and do not affect one another, allowing for individual adjustment of the position of any one wheel without affecting the positions of the other wheels, thus providing greater flexibility in wheel positioning. Of course, in other embodiments, the number of centering mechanisms 10 is not limited to the above description; for example, it could be three or six.

[0060] For example, in another embodiment, two centering mechanisms 10 may be provided, each centering mechanism 10 for supporting two wheels on the same side of the vehicle 200, wherein the two centering mechanisms 10 are symmetrically arranged about the axis of length or the axis of width of the garage conversion platform. For example, one centering mechanism 10 is used to support the two front wheels of the vehicle, and the other centering mechanism 10 is used to support the rear wheels of the vehicle, which is advantageous for each centering mechanism 10 to support one front wheel and one rear wheel.

[0061] In one embodiment, such as Figure 5 and Figure 6As shown, the centering mechanism 10 includes a bracket 12, a first transmission assembly 11, and a drive member 13. The drive member 13 is connected to the transmission assembly and is used to drive the first transmission assembly 11 to move. The first transmission assembly 11 is mounted on the bracket 12 and is used to support the wheels. When the drive member 13 drives the first transmission assembly 11 to move, it can drive the wheels to move, thereby driving the vehicle 200 to move and adjust its position.

[0062] Please continue reading. Figure 5 and Figure 6 The first transmission assembly 11 includes a drive shaft 111, multiple drive sprockets 112, and multiple drive chain plates 113. The drive shaft 111 is mounted on a frame and can rotate relative to the frame. A drive unit 13 is connected to the drive shaft 111 to drive its rotation. Multiple drive sprockets 112 are arranged side-by-side along the axial direction of the drive shaft 111, and the drive shaft 111 is connected to the multiple drive sprockets 112 to drive their rotation. The drive chain plates 113 carry the wheels. Multiple drive chain plates 113 are laid side-by-side along the radial direction of the drive shaft 111 on the drive sprockets 112, meshing with and transmitting power to the drive sprockets 112. When the drive sprockets 112 rotate, they can drive the multiple drive chain plates 113 to move, thereby moving the wheels on the drive chain plates 113. The size of the chain plates can be customized according to the size of the garage conversion platform 30, allowing for a larger transmission area to accommodate vehicles 200 of most sizes, thus increasing applicability. In other embodiments, the transmission method of the first transmission component 11 is not limited to the transmission method of sprockets and chain plates described above, but can also be other transmission methods, such as belt drive, where the transmission chain plate 113 is set on a conveyor belt and is conveyed by the conveyor belt, or rollers are used for conveying.

[0063] like Figure 5 and Figure 6 As shown, the centering mechanism 10 also includes a second transmission assembly 15. The second transmission assembly 15 extends radially along the transmission shaft 111 and is disposed on the side of the bracket 12, and is connected to the drive member 13 and the first transmission assembly 11 respectively. By setting the second transmission assembly 15 for transmission, the position of the drive member 13 can be changed to avoid the placement of other components, making the overall structural layout more compact.

[0064] like Figure 5 As shown, the centering mechanism 10 also includes a housing 14, which is disposed on the side of the bracket 12. The second transmission component 15 is disposed inside the housing 14. This can prevent foreign objects from falling into the second transmission component 15 and the drive component 13, which could cause transmission jamming. This greatly reduces the failure rate of the centering mechanism 10, helps to improve the service life of the drive component 13, and ensures that the drive component 13 and the second transmission component 15 are securely installed.

[0065] In one embodiment, the driving component 13 is a drive motor, and the second transmission assembly 15 includes a driving sprocket 151, a chain, and a driven sprocket 152. The driving sprocket 151 is connected to the output shaft of the drive motor, the driven sprocket is connected to the transmission shaft 111, and the chain is meshed with the driving sprocket 151 and the driven sprocket 152. Thus, the drive motor drives the transmission shaft 111 to rotate. Of course, in other embodiments, the second transmission assembly 15 is not limited to the transmission method described above; for example, it can also be a gear drive or a belt drive.

[0066] like Figure 7 and Figure 8 As shown, the pressure detector 20 includes a base 21, a support plate 22, a rotating component 23, and a pressure sensor 24. The support plate 22 supports the centering mechanism 10. The rotating component 23 is located between the base 21 and the support plate 22 and is connected to both the base 21 and the support plate 22. It is used to rotate and tilt the support plate 22 relative to the base 21 in response to external forces. The pressure sensor 24 is mounted on the base 21 and connected to the rotating component 23. It is used to measure the pressure value on the support plate 22. It is understood that when the vehicle 200 drives onto the garage conversion platform 30 and the wheel is positioned on the corresponding centering mechanism 10, the pressure applied by the wheel causes the centering mechanism 10 to deform. The rotating component 23 responds to the external force, allowing the support plate 22 to rotate and tilt at any angle, thus adapting to the deformed centering mechanism 10. This allows the support plate 22 to fit snugly against the centering mechanism 10, making the measurement by the pressure sensor 24 more accurate and improving the monitoring accuracy of the pressure detector 20 at the contact point of the wheel on the centering mechanism 10.

[0067] like Figure 7 As shown, the rotating component 23 includes a rotating shaft 231 and a rotating part 232. One end of the rotating shaft 231 is fixed to the base 21, and the other end extends toward the support plate 22. The rotating part 232 is rotatably mounted on the rotating shaft 231 and can tilt relative to the rotating shaft 231. The support plate 22 is mounted on the rotating part 232 and can rotate and tilt relative to the rotating shaft 231 under the drive of the rotating part 232, so as to adapt to the centering mechanism 10 which is deformed by pressure.

[0068] Specifically, such as Figure 2 As shown, the support plate 22 is attached to and connected to the bottom of the bracket 12 of the centering mechanism 10. When the centering mechanism 10 is subjected to the pressure of the wheel, the bracket 12 deforms locally. The support plate 22 rotates and tilts relative to the base 21 through the rotating component 23, thereby adapting to the deformed bracket 12 and making the pressure measurement accuracy more precise. Of course, the support plate 22 can also be connected to other structures on the centering mechanism 10.

[0069] The support plate 22 is detachably connected to the centering mechanism 10, and the base 21 is detachably connected to the garage conversion platform 30. This facilitates the installation and subsequent disassembly and maintenance of the pressure monitor.

[0070] Specifically, such as Figure 9 As shown, the support plate 22 has multiple connection holes 221. Fasteners are inserted into the connection holes 221 and connect the support plate 22 and the centering mechanism 10. The fasteners are bolts, screws, etc. Similarly, the base 21 and the garage conversion platform 30 are also detachably connected by bolts or screws.

[0071] like Figure 7 As shown, the pressure sensing element 24 has a mounting end 241 and a pressure bearing end 242 arranged opposite to each other. The mounting end 241 is connected to the base 21, and the pressure bearing end 242 is connected to the rotating element 23. A clearance gap 243 is provided between the pressure bearing end 242 and the base 21 so that the pressure bearing end 242 is suspended. This reduces the requirement for the flatness of the mounting surface of the base 21 and avoids the pressure response of the pressure bearing end 242 being affected by the unevenness of the mounting surface of the base 21.

[0072] In one embodiment, the pressure sensing element 24 is either a pressure sensor or a pressure detector, for example, the pressure sensing element 24 is a weighing sensor.

[0073] In one embodiment, multiple pressure detectors 20 are provided, and each centering mechanism 10 is equipped with multiple pressure detectors 20. The multiple pressure detectors 20 are distributed at the bottom of the centering mechanism 10 to measure the pressure values ​​at multiple points on the centering mechanism 10 in order to accurately determine the position of the wheel.

[0074] Specifically, each centering mechanism 10 is equipped with four pressure detectors 20, which are distributed at the four corners of the support 12.

[0075] In one embodiment, the prompt is a display screen 50, positioned above the garage transfer platform 30 and facing the front of the vehicle 200, so that the driver can see the message "Parking complete" or "Parking incomplete" displayed on the screen. Of course, in other embodiments, the prompt can be configured with other structures, and the prompting method is not limited to the text prompts described above. For example, in another embodiment, the prompt is an audio device that can emit a voice prompt such as "Parking complete" or "Parking incomplete" after the parking requirements are met.

[0076] like Figure 10 As shown, this application also provides a parking method based on the aforementioned parking device 100, which simplifies parking difficulties and improves parking comfort. The parking method includes the following steps:

[0077] S1. The vehicle 200 drives into the garage conversion platform 30, and based on the detection and pressure value signal of the pressure detector 20, the wheels 201 are adjusted to be located on the corresponding centering mechanism 10, and a parking signal is generated; wherein, the parking signal includes a parking in place signal and a parking not in place signal;

[0078] S2. Issue a parking reminder based on the parking signal;

[0079] S3. Perform the parking operation according to the parking prompt; specifically, the prompt will be "parking completed" and the driver or parking attendant can get out of the car and perform the parking operation after receiving the prompt.

[0080] S4. Detect the pressure value of the vehicle on the centering mechanism and generate a pressure value signal;

[0081] S5. Obtain the current position of each wheel based on the pressure value signal, and obtain the position of the axial center line of the garage conversion platform 30;

[0082] S6. Based on the current position of each wheel and the position of the axial centerline of the garage conversion platform 30, obtain the target position of each wheel's movement, the path of each wheel's movement, and the corresponding running time of the centering mechanism 10.

[0083] S7. The centering mechanism 10 adjusts the position of the wheel according to the path of the wheel movement so that the axial center line of the wheel is aligned with the axial center line of the garage conversion platform 30.

[0084] S8, the transporter moves the vehicle to the garage for storage.

[0085] Step S1 specifically includes the following steps: S21: Detect whether vehicle 200 meets the parking capacity specifications of the garage; S22: Detect whether vehicle 200 is parked in place. If it does not meet the parking capacity specifications and / or is not parked in place, a parking incomplete signal is generated and the position of vehicle 200 is readjusted; S23: If it meets the parking capacity specifications and is parked in place, a parking complete signal is generated.

[0086] In one embodiment, step S21, detecting whether the vehicle meets the garage's capacity specifications, specifically includes the following steps: detecting whether the vehicle is within a preset length range; detecting whether the vehicle is within a preset width range; and detecting whether the vehicle is within a preset height range. This can be understood as the preset length, width, and height ranges on the garage transfer platform 30 forming a virtual three-dimensional space for judgment. As long as the vehicle 200 does not exceed this three-dimensional space, the vehicle 200 meets the garage's capacity specifications. This allows for determining whether the size of the vehicle 200 is suitable for the garage's capacity and prevents the vehicle 200 from protruding from the garage transfer platform 30 during transport, thus avoiding scratches on the vehicle 200.

[0087] Step S21 specifically includes the following steps: S211: Detecting whether the vehicle is located within the preset length range; S212: Detecting whether the vehicle is located within the preset width range; S213: Detecting whether the vehicle is located within the preset height range.

[0088] In one embodiment, a parking detector 40 is used to detect whether the vehicle 200 meets the parking garage's specifications. The parking detector 40 includes a vehicle length sensor 42, a vehicle height sensor 41, and a vehicle width sensor 43. The vehicle length sensor 42 is used to detect whether the vehicle 200 is within a preset length range, the vehicle height sensor 41 is used to detect whether the vehicle 200 is within a preset height range, and the vehicle width sensor 43 is used to detect whether the vehicle 200 is within a preset width range, to ensure that the vehicle 200's dimensions do not exceed the garage's parking garage specifications. Additionally, the vehicle width sensor 43 can also be used to detect whether the vehicle 200 is properly aligned after it has been aligned.

[0089] In one embodiment, the vehicle length sensor 42, vehicle height sensor 41, and vehicle width sensor 43 are all configured as photoelectric devices, such as photoelectric sensors. The photoelectric devices use through-beam photoelectric detection and / or reflective photoelectric detection methods for detection. When the vehicle body blocks the light emitted by the photoelectric device, causing the photoelectric device to not receive a light signal, it indicates that the vehicle 200 does not meet the vehicle specifications; when the photoelectric device receives a light signal, it indicates that the vehicle 200 meets the vehicle specifications.

[0090] In step S22, detecting whether the vehicle is parked correctly includes the following steps: detecting whether the pressure value of the centering mechanism changes and generating a corresponding pressure value signal; comparing whether the changed pressure value is within a preset threshold range based on the pressure value signal; if not, readjusting the vehicle position; if yes, indicating that the vehicle is parked correctly and generating a parking signal.

[0091] In one embodiment, when performing step S22, it is detected whether the pressure value of each centering mechanism 10 is within a preset threshold range. If all are within the preset threshold range, it indicates that the vehicle has been parked in place. If the pressure value of at least one centering mechanism 10 is not within the preset threshold range, the vehicle position is readjusted. For example, when two centering mechanisms are set, they correspond to the front and rear wheels of the vehicle 200 respectively, and the two centering mechanisms 10 are placed on both sides of the central axis of the garage conversion platform 30. Then, the pressure change of the two centering mechanisms is measured. If four centering mechanisms are set, the pressure change of the four centering mechanisms is detected.

[0092] The pressure detector in any of the above embodiments detects the pressure on the centering mechanism and generates a pressure value signal. The controller determines whether the vehicle has stopped properly based on the pressure value signal and generates a stopping signal. A prompter, as described in any of the above embodiments, receives the stopping signal. The prompter is electrically and / or signalally connected to the controller. After receiving the stopping signal, the prompter issues a corresponding "stopping complete" or "stopping incomplete" prompt. That is, the parking prompt can be a voice or text prompt such as "stopping complete" issued by the prompter, and the prompt style is not limited.

[0093] In one embodiment, the pressure detector 20 detects the pressure exerted by the wheels on the centering mechanism 10 and transmits the pressure value signal to the controller. The controller obtains the current position of each wheel based on the pressure value signal, and obtains the target position of each wheel's movement, the path of each wheel's movement, and the corresponding running time of the centering mechanism 10 based on the current position of each wheel and the position of the axial center line of the garage conversion platform 30.

[0094] In step S5, preferably, the pressure values ​​of multiple points on the centering mechanism 10 are detected. The current wheel position can be obtained based on the pressure values ​​of multiple points, thereby improving the accuracy of wheel position calculation. Of course, in other embodiments, the pressure values ​​of any number of points on the centering mechanism 10 can be measured. There is no limitation here. For example, one point or four points can be measured.

[0095] For example, in one embodiment, the pressure values ​​at four points on the centering mechanism 10 are detected, with the four points located at the four corners of the centering mechanism 10, thus ensuring more accurate wheel position calculation.

[0096] The parking method also includes step S9: After the vehicle 200 is aligned, the pressure value of the current alignment mechanism 10 is detected to determine the position of the wheel after alignment and compare it with the target position of the wheel to determine whether the vehicle 200 is aligned. If the positions are consistent, the vehicle 200 is aligned. If they are inconsistent, the alignment mechanism 10 readjusts the position of the wheel 201 to make the vehicle 200 aligned.

[0097] Step S8 specifically includes the following steps: S81: Adjust the axial spacing between multiple clamping arm groups to match the position of the wheel; S82: The clamping arm groups clamp the corresponding wheel to transport the vehicle to the garage for storage.

[0098] Step S81 specifically includes the following steps: S811: Obtain the wheelbase based on the current position of the wheel; S812: Adjust the spacing between multiple clamping arm groups according to the wheelbase to match the wheel position. Specifically, along the vehicle axis, adjust the spacing between every two clamping arm groups to match the wheelbase, so that the clamping arm groups correspond to the corresponding wheel positions.

[0099] Step S82 specifically includes the following steps: S821: Determine whether the positions of the wheel and the clamping arm assembly correspond; S822: If they do not correspond, adjust the position of the transporter itself and the position of the clamping arm assembly; S823: If they correspond, the transporter extends the clamping arm assembly and clamps the corresponding wheel, transporting the vehicle to the garage for storage.

[0100] Among them, photoelectric detection is used to detect whether the position of the wheel and the clamping arm assembly is aligned.

[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0102] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
