[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0026] See Figures 1 to 6 The vehicle parking device of the present invention includes a first actuator 4 disposed on the rear side of the wheel, a second actuator 5 disposed on the front side of the wheel, a controller, and a tilt sensor. Both the first actuator 4 and the second actuator 5 include a fixing device 1, a deployment device 2, and a stop assembly 3. The fixing device 1 and the stop assembly 3 are connected via the deployment device 2. The fixing device 1 can be connected to the vehicle frame via a sliding rail or quick-connect interface to improve the ease of modification. The deployment device 2 and the tilt sensor are both electrically connected to the controller. The tilt sensor can be mounted on the vehicle frame. The controller is configured as follows: Based on the angle signal obtained from the tilt sensor, if the vehicle pitch angle corresponding to the angle signal is positive, the vehicle is in an uphill parking state; if the vehicle pitch angle corresponding to the angle signal is negative, the vehicle is in a downhill parking state. When the vehicle is parked on an uphill slope, the unfolding device 2 of the first actuator 4 is unfolded. The unfolding device 2 drives the stop assembly 3 to move, so that the stop assembly 3 of the first actuator 4 is supported on the ground and abuts against the rear side of the wheel. At this time, the upper end of the vehicle parking device is fixed to the frame and the lower end abuts against the ground, which can provide relatively stable support for the corresponding stop assembly 3. At the same time, the stop assembly 3 abuts against the rear side of the wheel to stop the wheel and prevent the vehicle from sliding downhill. When the vehicle is parked on a downhill slope, the deployment device 2 of the second actuator 5 is deployed. The deployment device 2 drives the stop assembly 3 to move, so that the stop assembly 3 of the second actuator 5 is supported on the ground and abuts against the front side of the wheel. At this time, the upper end of the vehicle parking device is fixed to the frame and the lower end abuts against the ground, which can provide relatively stable support for the corresponding stop assembly 3. At the same time, the stop assembly 3 abuts against the front side of the wheel to stop the wheel and prevent the vehicle from sliding downhill.

[0027] In some preferred embodiments, wheel speed sensors or vehicle speed sensors can be used to detect whether the vehicle is parked, while a parking button can be provided for manual activation by the driver. The controller only determines that the vehicle is in a parked state and activates the onboard parking device to prepare for assisted parking when the wheel speed sensors or vehicle speed sensors detect that the vehicle speed is zero and the driver has manually activated the parking button. In other embodiments, existing inertial navigation units can also be used to detect vehicle speed and tilt angle.

[0028] As a preferred implementation method, such as Figure 1As shown, the stop assembly 3 includes a propulsion device 301 and a stop block 302. The fixed end of the propulsion device 301 is connected to the unfolding device 2, and the telescopic end of the propulsion device 301 is connected to the stop block 302. The stop block 302 forms a stop surface 306 for contacting the wheel. In this embodiment, after the unfolding device 2 is unfolded, the propulsion device 301 is parallel to the ground. The propulsion device 301 extends in a direction parallel to the ground, driving the stop block 302 closer to the wheel to ensure that the stop surface 306 of the stop block 302 is in close contact with the wheel. When the driver is ready to drive away, the driver can press the retraction button. After the controller receives the retraction signal from the retraction button, the propulsion device 301 can retract in a direction parallel to the ground, driving the stop block 302 away from the wheel. The unfolding mechanism retracts, allowing the vehicle to move normally.

[0029] As a preferred implementation method, such as Figure 1 As shown, the stop surface 306 is an arc-shaped stop surface, which is configured to fit against the wheel so that the wheel can abut against the stop block 302.

[0030] As a preferred implementation method, such as Figure 1 As shown, the stop assembly 3 also includes a first pressure sensor 304 disposed on the arc-shaped stop surface. The arc-shaped structure of the arc-shaped stop surface facilitates the contact between the first pressure sensor 304 and the wheel, making the pressure value applied to the wheel detected by the first pressure sensor 304 more accurate. The first pressure sensor 304 is electrically connected to the controller, which is configured as follows: When the vehicle is in an uphill or downhill parking state, the control propulsion device 301 pushes the stop block 302 toward the wheel, and receives the first pressure from the first pressure sensor 304 in real time. When the first pressure reaches the first pressure target value, the propulsion device 301 is stopped and locked. At this time, the arc-shaped stop surface is tightly against the wheel, and the stop block 302 applies sufficient resistance force to the wheel to prevent the vehicle from slipping and improve the safety and reliability of parking.

[0031] In a preferred embodiment, the vehicle parking device further includes a tire pressure sensor for detecting the tire pressure of the wheels, and the controller is further configured to: The controller receives the tire pressure data from the tire pressure detection sensor and adjusts the first pressure target value according to the tire pressure data to ensure that the stop block 302 can apply sufficient and safe resistance force under different tire pressures. When the tire pressure is detected to be too low, the system automatically reduces the first pressure target value to prevent excessive compression of the tire and damage. When the tire pressure is normal or too high, the system maintains or appropriately increases the first pressure target value to ensure sufficient braking force.

[0032] In some preferred embodiments, the vehicle parking device further includes an alarm device 9, which is electrically connected to a controller. The alarm device 9 can be an audible and visual alarm device, and the controller is further configured to: When the stop assembly 3 is in contact with the wheel, if the first pressure is not within the predetermined safe pressure range, the vehicle is at risk of slippage. The controller will activate the alarm device 9 to issue a corresponding audible and visual alarm to remind the driver to check the vehicle promptly and eliminate the slippage risk. The controller can adjust the predetermined safe pressure range based on the tire pressure data detected by the tire pressure sensor.

[0033] The controller can also be configured as: When the vehicle speed is detected to be zero and the parking button is manually triggered, the audible and visual alarm device will sound a corresponding alarm to prompt the driver to activate the vehicle parking assist device.

[0034] In other embodiments, when the vehicle is about to leave, after the on-board parking device is retracted, the controller can also trigger the audible and visual alarm device to issue a corresponding audible and visual alarm.

[0035] As a preferred embodiment, such as Figure 1 As shown, the stop assembly 3 also includes a support plate 303, which is connected to the propulsion device 301. The support plate 303 forms a support surface 307 for contacting the ground. The support plate 303 is preferably made of a wear-resistant material with high friction to improve the service life of the vehicle parking device and improve the stability of the stop assembly 3.

[0036] As a preferred embodiment, such as Figure 1 As shown, the stop assembly 3 also includes a second pressure sensor 305 disposed on the support surface 307, and the controller is further configured to: When the vehicle is in an uphill or downhill parking state, the controller controls the deployment device 2 to deploy. It receives the second pressure from the second pressure sensor 305 in real time. When the second pressure reaches the second pressure target value, the support surface 307 successfully contacts the ground, stops the deployment, and locks the deployment device 2. The contact between the support surface 307 and the ground provides sufficient force to the stop assembly 3, ensuring that the stop assembly 3 does not shift during parking, thus improving the stability of the vehicle parking device.

[0037] In some embodiments, the controller may be a single controller capable of handling all functions, or it may be configured as a distributed controller, delegating some functions to sensor nodes.

[0038] As a specific implementation method, such as Figure 1 and Figure 2As shown, the unfolding device 2 includes a first rotating device 201, a telescopic device 202, and a second rotating device 203. The fixed end of the telescopic device 202 and the fixed device 1 are rotatably connected through the first rotating device 201. The telescopic end of the telescopic device 202 and the stop assembly 3 are rotatably connected through the second rotating device 203. The first rotating device 201, the telescopic device 202, and the second rotating device 203 are all electrically connected to a controller. When the unfolding device 2 unfolds, the first rotating device 201 and the second rotating device 203 rotate, driving the telescopic device 202 and the stop assembly 3 to rotate, so that the telescopic device 202 is perpendicular to the ground and the propulsion component of the stop assembly 3 is parallel to the ground. At the same time, the telescopic device 202 extends, bringing the stop assembly 3 closer to the ground until the stop surface 306 abuts against the ground and the second pressure reaches the second target pressure value.

[0039] In some embodiments, multiple first pressure sensors 304 may be provided on the stop surface 306 to increase the detection area and prevent the stop surface 306 from stopping before it fully contacts the wheel due to stones or other foreign objects at the location of a certain first sensor 304. When the push device 301 pushes the stop block 302 closer to the wheel and detects a large deviation between the first pressures detected by the multiple first pressure sensors 304, or when the first pressure can never reach the first pressure target value, i.e., when there are foreign objects between the stop block 302 and the wheel, the controller controls the first rotating device 201 to rotate, causing the stop assembly 3 to swing. After the swinging stop assembly 3 contacts the foreign object, it drives the foreign object to move, causing the foreign object to roll down the slope. After controlling the stop assembly 3 to swing multiple times, the controller controls the stop assembly 3 to approach the wheel again to contact the wheel. If a large deviation between the first pressures detected by the multiple first pressure sensors 304 is still detected, or the first pressure can never reach the first pressure target value, the controller controls the alarm device 9 to issue an audible and visual alarm to remind the driver to remove the foreign object. Multiple second pressure sensors 305 can also be installed on the support surface 307 to increase the detection area and prevent the telescopic device 202 from stopping before the support surface 307 fully contacts the ground due to stones or other foreign objects at the location of a second sensor 305. When the telescopic device 202 moves the stop assembly 3 downwards and detects a large deviation between the second pressures detected by the multiple second pressure sensors 305, or when the second pressure fails to reach the target value, the first rotating device 201 can also be driven to rotate to clean the foreign objects at the bottom of the stop assembly 3.

[0040] In some specific examples, the vehicle parking device also includes a control unit 6. The control unit includes a housing 7, a latch 8, operation buttons 10, and indicator lights 11. The latch 8 is used to install the housing 7 on the vehicle. An audible and visual alarm device is installed on the housing 7. The controller is located inside the housing 7. The bottom of the housing 7 is provided with a wiring inlet / outlet 12. Wires can pass through the wiring inlet / outlet 12 and electrically connect the controller and the sensor or electrically connect the controller and the actuator. The housing 7 is provided with multiple operation buttons. The operation buttons 10 may include a parking button and a retraction button. The housing 7 is provided with indicator lights 11 corresponding to the operation buttons 10 to indicate the current vehicle status. The housing 7 is provided with a display 13 to display the first pressure and / or second pressure data for the driver's convenience.

[0041] Based on the vehicle parking device mentioned in the above technical solution of the present invention, the present invention also provides a parking anti-slip method, which can be used in the vehicle parking device of the present invention, and includes the following steps: Obtain the vehicle's parking status; When the vehicle is parked on an uphill slope, the first actuator 4 is controlled to unfold so that the corresponding stop assembly 3 is supported on the ground and abuts against the rear side of the wheel. When the vehicle is parked on a downhill slope, the second actuator 5 is controlled to unfold so that the corresponding stop assembly 3 is supported on the ground and abuts against the front side of the wheel.

[0042] This invention provides a preferred vehicle parking device, which includes a first actuator 4 disposed behind the wheel, a second actuator 5 disposed in front of the wheel, a controller, a tilt sensor, and a speed sensor. Both the first actuator 4 and the second actuator 5 include a fixing device 1, a deploying device 2, and a stop assembly 3. The fixing device 1 and the stop assembly 3 are connected via the deploying device 2. The fixing device 1 is connected to the vehicle frame via a quick-connect interface. The tilt sensor is disposed on the vehicle frame. A speed sensor and a tire pressure sensor are disposed at the wheel. The deploying device 2 includes a first rotating device 201, a telescopic device 202, and a second rotating device 203. The stop assembly 3 includes a pushing device 301, a stop block 302, and a support plate 303. The fixed end of the telescopic device 202 is connected to the fixing device 1 via the first rotating device 201. The telescopic end of the telescopic device 202 is connected to the fixed end of the pushing device 301 via the second rotating device 203. The fixed end of the pushing device 301 is also connected to the support plate 303. The telescopic end of device 301 is connected to a stop block, which forms an arc-shaped stop surface. A first pressure sensor 304 is provided on the arc-shaped stop surface, and a second pressure sensor 305 is provided on the support plate 303. The first rotating device 201, telescopic device 202, second rotating device 203, tilt sensor, speed sensor, tire pressure detection sensor, first pressure sensor, and second pressure sensor are all electrically connected to the controller. The vehicle parking device also includes a control unit, which includes a housing 7, a buckle 8, an operation button 10, an indicator light 11, and an audible and visual alarm device. The buckle 8 is used to install the housing 7 on the vehicle. The audible and visual alarm device is located on the housing 7. The controller is located inside the housing 7. Wires can pass through the inlet and outlet ports 12 on the housing 7 and electrically connect the controller and the sensor or electrically connect the controller and the actuator. The housing 7 is provided with an operation button 10, which includes a parking button and a retraction button. An indicator light 11 is provided on the housing 7 corresponding to the operation button 10. A display 13 is provided on the housing 7. After the driver stops the vehicle, they can press the parking button. The controller receives the wheel rotation stopped signal detected by the speed sensor and the parking signal from the parking button, preparing for assisted parking. The controller activates the audible and visual alarm device to trigger the corresponding parking start alarm and illuminates the indicator light 11 corresponding to the parking button. The controller receives the angle signal from the tilt sensor and determines whether the vehicle is in an uphill or downhill parking state based on the vehicle pitch angle corresponding to the angle signal. If the vehicle is in an uphill parking state, the controller controls the first actuator 4 to deploy, so that the stop assembly 3 of the first actuator 4 supports the ground and abuts the rear side of the wheel. If the vehicle is in a downhill parking state, the controller controls the second actuator 5 to deploy, so that the corresponding stop assembly 3 supports the ground and abuts the front side of the wheel.The process of the controller controlling the deployment of the first or second actuator is as follows: The controller controls the first rotating device 201 and the second rotating device 203 to rotate, thereby driving the telescopic device 202 to be perpendicular to the ground and the stop assembly 3 to be parallel to the ground. At the same time, the controller controls the telescopic device 202 to extend until the second pressure detected by the second pressure sensor 305 reaches the second pressure target value, so that the upper end of the vehicle parking device is connected to the frame and the lower end abuts the ground, providing stable support for the stop assembly 3. Then the controller controls the propulsion device 301 to push the stop block 302 closer to the wheel until the first pressure detected by the first pressure sensor 304 reaches the first pressure target value, so that the arc-shaped stop surface of the stop block 302 abuts the wheel, and the stop block 302 provides sufficient braking force to the wheel to achieve parking assistance. The first pressure target value is adaptively adjusted based on the tire pressure signal detected by the tire pressure monitoring sensor. When the tire pressure is detected to be too low, the first pressure target value is reduced to prevent excessive tire compression and damage. When the tire pressure is normal or too high, the first pressure target value is maintained or appropriately increased to ensure sufficient braking force. At the same time, the controller adjusts the predetermined safe pressure range based on the tire pressure data. If the first pressure is not within the predetermined safe pressure range during parking, the controller controls the audible and visual alarm device to trigger the alarm corresponding to the pressure abnormality, alerting surrounding personnel to safety and prompting them to check the vehicle in time to eliminate the risk of slippage. At this time, the display 13 can display the first pressure of the first pressure sensor 304 of the actuator corresponding to each wheel to check which wheel has insufficient braking force. When the vehicle is about to leave, the driver presses the retraction button, the indicator light 11 corresponding to the parking button is lit, the controller controls the sound and light alarm device to activate the corresponding sound and light alarm, the propulsion device 301 retracts and drives the stop block 302 away from the wheel, the first rotating device 201 and the second rotating device 203 rotate, and at the same time the telescopic device 202 retracts, so that the vehicle parking device is stored in the retraction device. Figure 3 The image shows the position close to the vehicle frame. The vehicle parking device of this invention ensures sufficient stability of the stop assembly 3 in the parking state by setting a second pressure sensor 305 on the support surface 307, and a first pressure sensor 304 on the arc-shaped stop surface to ensure that the stop assembly 3 provides sufficient braking force to the vehicle, achieving a relatively safe and reliable parking. Furthermore, the first pressure sensor 304 can monitor the braking effect of the stop assembly 3 in real time, alerting nearby personnel when the first pressure is not within a predetermined safe pressure range, thus preventing the vehicle from rolling away.

[0043] As can be seen from the above description, the advantages of the present invention are as follows: First, the second pressure sensor ensures the overall stability of the vehicle parking device; second, the propulsion device pushes the stop block, and the stop block forms an arc-shaped stop surface to ensure that the stop block abuts the wheel more tightly, thereby improving braking force; third, the first pressure sensor ensures that sufficient braking force is provided, and can issue a warning to nearby personnel based on the first pressure detected by the first pressure sensor to prevent the vehicle from rolling away and improve safety; fourth, the fixing device can be used to connect with the vehicle frame, making modification convenient and providing strong adaptability to different vehicle models.
