Description

Technical Field

[0001] The present invention belongs to the technical field of parking equipment, and in particular relates to a swing arm ground lock with wireless charging and a charging method thereof. Background Art

[0002] With the increasing popularity of new energy vehicles, wireless charging technology is gaining adoption in specific scenarios, such as high-end shopping malls and private parking spaces, due to its advantages of instant charging, plug-and-play functionality, reduced operating costs, and improved user experience. For example, Chinese patent publication CN101673962A discloses a wireless charging system for electric vehicles, designed to address the leakage and mechanical wear issues of traditional charging equipment. This wireless charging system comprises a transmitter connected to the power grid and a receiver mounted on the vehicle, simplifying the charging process through wireless transmission. In high-end shopping malls, users often seek upgraded services, including parking and charging reservations, for a convenient shopping experience. In private parking spaces, users need to verify parking space ownership, i.e., clarify their use rights to prevent unauthorized occupancy. Both scenarios rely on smart ground locks to address parking space occupancy. However, currently, meeting both parking space occupancy and charging requirements can only be achieved by installing separate smart ground locks and charging stations. This not only results in high equipment costs, but also increases the floor space occupied by two independent systems, hindering the efficient use of parking spaces.

[0003] Existing technologies struggle to integrate parking locks into wireless charging systems, resulting in the following significant drawbacks: First, in public spaces, to address the issue of new energy vehicles not leaving the vehicle promptly after fully charging, existing solutions require data integration through different hardware, such as the ground lock controller and the charging station management system. This results in high development costs and poor data synchronization stability, often leading to delays or errors and the inability to bill and collect parking fees in real time. Second, during the charging process, users must pay for parking and charging separately, resulting in redundant steps.

[0004] Therefore, there is an urgent need to provide a swing arm ground lock with wireless charging and a charging method thereof to integrate the occupying and charging functions, reduce costs and space occupancy, and optimize user experience. Summary of the Invention

[0005] In response to the problems in the related technology, the present invention proposes a rocker arm ground lock with wireless charging and a charging method thereof to overcome the above-mentioned technical problems existing in the existing related technology. Through an integrated design, charging and parking billing data are uniformly processed, the development cost of equipment docking is reduced, and users are supported to pay both fees at one time, simplifying the payment process.

[0006] The technical solution of the present invention is implemented as follows: a rocker arm ground lock with wireless charging is installed on a parking space; it includes:

[0007] The ground lock module includes a base fixedly mounted on the parking space, a car blocking body hinged to the base, and a driving rod that drives the car blocking body to change its posture; the car blocking body is composed of a rocker arm and a baffle hinged together; the car blocking body has three postures:

[0008] First posture: the parking block body stands vertically on the base, the rocker arm and the baffle are coplanar, locking the parking space;

[0009] Second posture: the main body of the parking brake is horizontally attached to the base, the rocker arm and the baffle are coplanar, and the parking space is open;

[0010] Third position: The rocker arm is upright, the baffle is horizontally extended and perpendicular to the rocker arm, the parking space is open and charging is activated;

[0011] The sensing module is provided on the baffle and is used to detect the vehicle's entry / exit / stop status and generate a sensing signal;

[0012] A wireless charging module includes a transmitter integrated into the fender, the transmitter being connected to an external power grid for wirelessly transmitting power to a vehicle receiver;

[0013] The control module is connected to the sensing module, ground lock module and wireless charging module. It is used to control the driving rod to switch the parking body posture according to the sensing signal, and generate an integrated deduction list based on the parking time and charging data.

[0014] This invention integrates the wireless charging transmitter within the baffle and utilizes the baffle's horizontal expansion to achieve highly adaptable wireless charging modules, physically integrating the ground lock and charging device into a single device. The control module directly manages the ground lock's posture control, charging start / stop, and vehicle sensor data, ensuring real-time, synchronized billing of both the ground lock and charging fees, reducing device integration and development costs and streamlining the payment process.

[0015] As a further improvement of the above solution, the rocker arm and the base are hinged to each other through a first magnetic attraction component, and the first magnetic attraction component includes a first magnetic block at the bottom of the rocker arm and a first electromagnet on the base;

[0016] The rocker arm and the baffle are hinged to each other via a second magnetic attraction component, wherein the second magnetic attraction component includes a second magnetic block on the top of the rocker arm and a second electromagnet on the baffle;

[0017] The first electromagnet and the second electromagnet are attracted to or separated from the corresponding magnetic blocks by turning on / off the power, thereby restricting the rotation angle.

[0018] By switching the electromagnets on and off, the magnetic block engages and disengages, enabling convenient adjustment of the vehicle's main position. De-energizing the first electromagnet releases the rocker arm to rotate horizontally, allowing for the second position; energizing it locks the arm in a vertical position, maintaining either the first or third position. Similarly, the second electromagnet precisely controls the flap's tilt angle. This design replaces mechanical buckles with electrically controlled magnetic attraction, minimizing wear, improving the reliability and responsiveness of position switching, and reducing drive energy consumption.

[0019] As a further improvement to the above solution, the rocker arm is composed of multiple hinged rocker arm units. Second magnetic assemblies are positioned between adjacent rocker arm units, with each second magnetic assembly spaced apart along the rocker arm's height. This multi-segment rocker arm unit, combined with the height-spaced second magnetic assemblies, allows the baffle to flip horizontally around the hinge axis to the correct position simply by de-energizing the electromagnet at the target height. This addresses charging alignment challenges caused by varying chassis heights across different vehicle models and prevents the risk of chassis collisions.

[0020] As a further improvement to the above solution, the first posture corresponds to the locked parking space; the second posture corresponds to the vehicle parked but not charging; and the third posture corresponds to the vehicle parked with the fender extended horizontally and charging. The first posture locks the parking space vertically; the second posture is horizontally stowed, allowing for normal parking; and the third posture activates wireless charging with the fender extended horizontally. A single device dynamically switches between these three scenarios, eliminating the need for separate equipment installation. This is particularly suitable for charging reservations in high-end shopping malls and for confirming ownership of private parking spaces.

[0021] As a further improvement to the above solution, the sensing module includes an image recognition unit mounted on the baffle to identify the vehicle's chassis height. Based on the chassis height, the control module de-energizes the second magnetic assembly at the corresponding height, causing the baffle to flip horizontally around the second magnetic assembly's hinge axis to a suitable position. The image recognition unit captures the vehicle's chassis height data in real time, and the linked control module precisely selects the height of the de-energized magnetic assembly, automatically flipping the baffle to the optimal charging distance. This eliminates the need for an additional lifting mechanism to adjust the height of the wireless charging module, preventing charging losses or device collisions caused by height misjudgment by traditional lifting mechanisms.

[0022] As a further improvement to the above solution, the sensing module also includes an ultrasonic sensor mounted on the baffle. In the third position, the ultrasonic sensor detects the vehicle's parking status vertically upward and provides feedback on parking duration to the control module. In this third position, the ultrasonic sensor detects vertically upward, continuously monitoring the vehicle's parking status through sound wave reflection. Compared to geomagnetic or infrared sensors, the ultrasonic sensor has greater penetration and is more resistant to environmental interference, resolving the issue of missing charges in "full parking" scenarios.

[0023] As a further improvement to the above solution, the second magnetic assembly is equipped with a stopper extending from the back of the second magnetic block to the hinge axis with the second electromagnet. The upper edge of the stopper is flush with the upper end surface of the second magnetic block, limiting the baffle's tilt angle to within a range of 0°-90°. The stopper forms a physical stop, preventing the baffle from overturning and damaging the circuitry, such as pulling on the charging cable beyond 90°. It also ensures that the baffle is absolutely level during charging, ensuring a stable and reliable charging process.

[0024] As a further improvement of the above solution, the control module is communicatively connected to a terminal to receive user instructions to control posture switching; the terminal includes a mobile phone, a remote controller or a vehicle-mounted controller.

[0025] A charging method for a swing arm ground lock with wireless charging is applied to the above-mentioned swing arm ground lock with wireless charging, and includes the following steps in a scheduled charging scenario:

[0026] S1. The user reserves the entry time T1 through the terminal's reservation system;

[0027] S2. After arriving at the parking space at time T1, the user sends a lock-down command through the terminal;

[0028] S3. The control module responds to the lock command and controls the vehicle body to switch from the first posture to the second posture or the third posture; when switching to the third posture, executing step S4; when switching to the second posture, executing step S5;

[0029] S4. When the vehicle is about to park, the sensing module obtains the vehicle chassis height through the image recognition unit, and the control module controls the baffle to flip to a horizontal state at a suitable height, and executes step S6;

[0030] S5. When the vehicle is about to park, the control module controls the vehicle body to fit horizontally with the base, and executes step S6;

[0031] S6. After the vehicle is parked, the ultrasonic sensor monitors the parking status of the vehicle; the control module records the actual parking start time T2 and monitors the charging status in real time; when the vehicle leaves the parking lot, the control module records the departure time T3 and simultaneously obtains the charging duration and charging power data;

[0032] S7 control module integration parking time T3-T2, and charging data, according to the pre-designed fee strategy to generate a total service fee order, the billing strategy includes parking fee exemption rules;

[0033] S8. After the vehicle leaves, the vehicle body is controlled to return to the first posture and a payment order is pushed to the user terminal.

[0034] The parking and charging processes are integrated through the reservation system. When leaving the parking lot, the charging data and parking duration are integrated to generate a single order. It supports pre-designed charging strategies, eliminates the cost of connecting the two systems, and simplifies the payment process.

[0035] As a further improvement of the above solution, the lock-down instruction execution process includes:

[0036] When switching to the second posture: the control module cuts off the power supply of the first electromagnet to separate it from the first magnetic block; the driving rod drives the vehicle blocking body to rotate horizontally until it fits with the base;

[0037] When switching to the third posture: the control module keeps the first electromagnet energized to lock the rocker arm in a vertical position; based on the chassis height data obtained by the image recognition unit, the power supply of the second magnetic attraction component at the corresponding height is cut off; the drive rod pushes the baffle to flip horizontally 90 degrees around the de-energized hinge axis; and the transmitter of the wireless charging module is activated;

[0038] The lock-up process after charging is completed includes:

[0039] When the lock is raised from the second posture: the driving rod is erected to the vertical position of the blocking vehicle body; the first electromagnet is energized to attract the first magnetic block;

[0040] When raising the car from the third position, the following steps are performed: the wireless charging module's transmitter is deactivated; the actuator pulls the baffle 90° vertically; the deactivated second magnetic assembly is reenergized, causing the second electromagnet to engage the second magnetic block; and the first electromagnet remains energized to lock the rocker arm. When lowering the car, the magnetic assembly at the corresponding height, selected based on image recognition, is deactivated, driving the baffle to precisely rotate 90° to a horizontal position. When raising the car, the transmitter is first deactivated, followed by the baffle's reset. This adaptive height adjustment mechanism significantly improves vehicle compatibility and addresses charging alignment challenges caused by varying chassis heights.

[0041] Beneficial effects:

[0042] (1) By integrating the wireless charging transmitter inside the baffle and using the baffle to block the main body of the vehicle to unfold horizontally to form a third posture, the wireless charging module is highly adapted, and the occupant ground lock and the charging device are physically integrated into a single device. The control module directly manages the ground lock posture control, charging start and stop, and vehicle sensing data, completely eliminating the external data interaction between the ground lock controller and the charging pile management system. This integrated architecture solves the high development cost and data delay problems caused by multi-system docking at the hardware level, ensures that the occupant fee and the charging fee are charged synchronously in real time, reduces the development cost of equipment docking, supports users to pay both fees at one time, and simplifies the payment process.

[0043] (2) The innovatively designed three-position conversion mechanism of the ground lock body: the first position locks the parking space vertically; the second position is horizontal, completely hidden in the ground, freeing up the entire parking space; the third position has the rocker arm upright and the baffle horizontally charged, using only the gap between the vehicle chassis to deploy the charging module. Compared with the traditional solution of separate ground locks and charging piles, this greatly reduces the ground space occupied and effectively reduces the overall installation cost of the ground locks and charging piles.

[0066] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0067] Example:

[0068] like Figure 1-Figure 7 As shown, this embodiment provides a rocker arm ground lock with wireless charging, which is installed on a parking space and includes a ground lock module 1, a sensing module 2, a wireless charging module 3, and a control module. The ground lock module 1 includes a base 11 fixedly installed on the parking space, a car blocking body 12 hinged to the base 11, and a driving rod 13 for driving the car blocking body 12 to change its posture. The car blocking body 12 is composed of a rocker arm 121 and a baffle 122. The driving rod 13 can be an electric push rod. Specifically, the embodiment uses a three-stage electric push rod, one end of which is hinged to the base 11 and the other end is connected to the baffle 122.

[0069] The vehicle blocking body 12 has three postures:

[0070] First posture: the parking block body 12 stands vertically on the base 11, and the rocker arm 121 and the baffle 122 are coplanar. The first posture corresponds to the parking space locked state;

[0071] Second posture: the parking block body 12 is horizontally attached to the base 11, the rocker arm 121 and the baffle 122 are coplanar, and the parking space is open; the second posture corresponds to the vehicle being parked and not charging;

[0072] The third posture: the rocker arm 121 is vertically upright, the baffle 122 is horizontally extended and perpendicular to the rocker arm 121, the parking space is open and charging is activated. The third posture corresponds to the charging state in which the vehicle is parked and the baffle 122 is horizontally extended.

[0073] In this embodiment, the first position vertically occupies the parking space, locks it in place, the second position is horizontally stowed, and opens for normal parking. In the third position, the flap 122 is horizontally deployed, activating wireless charging. A single device dynamically switches between these three scenarios, eliminating the need for separate equipment installation. This is particularly suitable for charging reservations in high-end shopping malls and for confirming ownership of private parking spaces.

[0074] In this embodiment, the rocker arm 121 and the base 11 are hingedly connected via a first magnetic assembly 123, which includes a first magnetic block 1231 at the bottom of the rocker arm 121 and a first electromagnet 1232 on the base 11. The rocker arm 121 and the baffle 122 are hingedly connected via a second magnetic assembly 124, which includes a second magnetic block 1241 at the top of the rocker arm 121 and a second electromagnet 1242 on the baffle 122. Specifically, each magnetic block can be a permanent magnet, and the first electromagnet 1232 and the second electromagnet 1242 are configured to engage or disengage with the corresponding magnetic block by turning the power on or off, thereby constraining the rotation angle. The electromagnets are coil windings.

[0075] This embodiment uses electromagnets to control the magnetic block's engagement and disengagement, enabling convenient adjustment of the vehicle's main body 12's posture. De-energizing the first electromagnet 1232 releases the rocker arm 121 to rotate horizontally, allowing for the second posture; energizing it locks the arm 121 in a vertical position to maintain the first or third posture. Similarly, the second electromagnet 1242 precisely controls the tilting angle of the baffle 122. This design replaces mechanical buckles with electrically controlled magnetic attraction, minimizing mechanical wear, improving the reliability and responsiveness of posture switching, and reducing drive energy consumption.

[0076] In this embodiment, the rocker arm 121 is composed of a plurality of hinged rocker arm 121 units; a second magnetic assembly 124 is provided between adjacent rocker arm 121 units, and each second magnetic assembly 124 is spaced apart along the height direction of the rocker arm 121, such as at intervals of 10 cm. Specifically, it includes a first rocker arm unit 1211 and a second rocker arm unit 1212; wherein the lower end of the first rocker arm unit 1211 is provided with a first magnetic block 1231, which cooperates with a first electromagnet 1232 on the base 11; the upper end of the first rocker arm unit 1211 is provided with a second magnetic block 1241, and the second magnetic block 1241 is hinged to a second electromagnet 1242; the second electromagnet 1242 is fixed to the lower end of the second rocker arm unit 1212, and the upper end of the second rocker arm unit 1212 is provided with another second magnetic block 1241, which is hinged to another second electromagnet 1242, and the second electromagnet 1242 is fixedly connected to the baffle 122. The multi-stage rocker arm 121, coupled with a second magnetic assembly 124 distributed along the height, allows the baffle 122 to flip horizontally around the second magnetic assembly's hinge axis to the desired position simply by de-energizing the electromagnet at the target height. This addresses the charging alignment challenges caused by varying chassis heights across different vehicle models and prevents the risk of chassis collisions. In other embodiments, a three- or four-stage rocker arm 121 can also be configured to accommodate different heights.

[0077] In this embodiment, the second magnetic assembly 124 is equipped with a stopper 125, which extends from the back of the second magnetic block 1241 to the hinge axis with the second electromagnet 1242. The upper edge of the stopper 125 is flush with the upper end surface of the second magnetic block 1241, limiting the tilting angle of the baffle 122 to within a range of 0°-90°. The provision of the stopper 125 forms a physical stop, preventing the baffle 122 from tilting too far and damaging the circuit, such as pulling on the charging cable beyond 90°. It also ensures that the baffle 122 is absolutely level during charging, ensuring a stable and reliable charging process.

[0078] The sensing module 2, mounted on the baffle 122, is used to detect the vehicle's entry / exit / stop status and generate a sensing signal. In this embodiment, the sensing module 2 includes an image recognition unit 21, such as a CCD camera, mounted on the baffle 122 to identify the vehicle's chassis height. The control module de-energizes the corresponding second magnetic component 124 based on the chassis height, causing the baffle 122 to flip horizontally about the hinge axis to an appropriate position. The image recognition unit 21 captures the vehicle's chassis height data in real time, and the linkage control module accurately selects the height of the de-energized magnetic component, causing the baffle 122 to automatically flip to the optimal charging distance. This eliminates the need for an additional lifting mechanism to adjust the height of the wireless charging module 3, thus avoiding charging losses or device collisions caused by height misjudgment by traditional lifting mechanisms.

[0079] Specifically, the image recognition unit 21 obtains the chassis height by the following process:

[0080] Step 1. Vehicle outline extraction: Capture continuous frame images of vehicles entering the vehicle, such as 30fps; separate moving vehicles using background subtraction; and output a binary mask of the vehicle outline.

[0081] Step 2. Key feature point positioning:

[0082] Tire contact point identification: Search for the point of maximum curvature at the bottom of the profile, where the tire contacts the ground, marked as points P1 and P2;

[0083] Identification of the lowest point of the chassis: Scan the point with the maximum Y coordinate at the bottom of the center axis of the profile, marked as point P3;

[0084] Step 3. Height calculation model:

[0085] Coordinate system establishment: The optical center of the camera is the origin O, the vertical direction is the Z axis, and the horizontal direction is the X axis;

[0086] Actual height calculation: H 底盘 =(f×H sensor ) / (d×k); where f is the focal length of the camera; H sensor is the pixel height of point P3 in the image, in pixels; d is the measured horizontal distance between the camera and point P3, which can be calibrated by the ultrasonic sensor 22; and k is the pixel size conversion coefficient.

[0087] In this embodiment, the sensing module 2 also includes an ultrasonic sensor 22 mounted on the baffle 122. In the third posture, the ultrasonic sensor 22 detects the vehicle's parking status vertically upward and provides feedback on parking duration data to the control module. In the third posture, the ultrasonic sensor 22 detects vertically upward, continuously monitoring the vehicle's parking status through sound wave reflection. Compared to geomagnetic or infrared sensors, the ultrasonic sensor 22 has strong penetration and is resistant to environmental interference, solving the problem of missing charges in "full occupied" scenarios. It should be noted that to prevent the sensing module 2 from being easily damaged by collisions, the probe of the sensing module 2 can be embedded in the mounting slot of the baffle 122 to prevent exposure.

[0088] The wireless charging module 3 includes a transmitter 31 integrated in the baffle 122, such as a copper induction coil. The transmitter 31 is connected to the external power grid and is used to wirelessly transmit power to the vehicle receiver 32; the receiver 32 on the vehicle can be a vehicle-mounted magnetic resonance receiving disk.

[0089] The control module, connected to the sensing module 2, the ground lock module 1, and the wireless charging module 3, controls the driving lever 13 to switch the posture of the vehicle blocking body 12 based on the sensing signal, and generates an integrated deduction bill based on the parking duration and charging data. The integrated deduction bill is a total order that includes the parking duration and charging data. The control module is connected to a terminal for communication and receives user commands to control the posture switching; the terminal can be a mobile phone, remote control, or vehicle controller.

[0090] like Figure 8 、 Figure 9 As shown, through the above solution of the present invention, the following steps are included in the scheduled charging scenario:

[0091] S1. The user reserves entry time T1 through the terminal's reservation system. If using an app, the reservation system integrates the parking and charging processes. Upon departure, the charging data and parking duration are combined to generate a single order. This supports pre-designed billing strategies, eliminates the cost of connecting the two systems, and simplifies the payment process.

[0092] S2. After arriving at the parking space at time T1, the user sends a lock-down command through the terminal;

[0093] S3. The control module responds to the lock command and controls the vehicle body 12 to switch from the first posture to the second posture or the third posture; the lock command execution process includes:

[0094] When switching to the second posture: the control module cuts off the power supply of the first electromagnet 1232 to separate it from the first magnetic block 1231; the driving rod 13 drives the vehicle blocking body 12 to rotate horizontally until it is in contact with the base 11; and step S5 is executed;

[0095] When switching to the third posture: the control module keeps the first electromagnet 1232 energized to lock the rocker arm 121 in the vertical position; based on the chassis height data obtained by the image recognition unit 21, the power supply of the second magnetic attraction component 124 at the corresponding height is cut off; the driving rod 13 pushes the baffle 122 to flip horizontally 90° around the de-energized hinge axis; the transmitter 31 of the wireless charging module 3 is activated; and step S4 is executed;

[0096] S4. When the vehicle is about to park, the sensing module 2 obtains the vehicle chassis height through the image recognition unit 21, and the control module controls the baffle 122 to flip to a horizontal state at a suitable height, and executes step S6;

[0097] S5. When the vehicle is about to park, the control module controls the vehicle body 12 to fit horizontally with the base 11, and executes step S6;

[0098] S6. After the vehicle is parked, the ultrasonic sensor 22 monitors the parking status of the vehicle; the control module records the actual parking start time T2 and monitors the charging status in real time; when the vehicle leaves, the control module records the departure time T3 and simultaneously obtains the charging duration and charging power data;

[0099] S7. The control module integrates the parking time T3-T2 and charging data to generate a total service fee order based on the pre-designed fee strategy. The billing strategy includes parking fee exemption rules; specifically, the parking fee exemption rules can be preferential policies such as free parking for a full hour of charging;

[0100] S8. After the vehicle leaves, the vehicle blocking body 12 is controlled to restore to the first posture, and a payment order is pushed to the user terminal.

[0101] The lock-up process after charging is completed includes:

[0102] When the lock is raised from the second position: the driving rod 13 raises the vehicle blocking body 12 to a vertical position; the first electromagnet 1232 is energized to attract the first magnetic block 1231;

[0103] When the vehicle is locked from the third position, the transmitter 31 of the wireless charging module 3 is deactivated; the drive rod 13 pulls the baffle 122 to rotate vertically 90°; the deactivated second magnetic assembly 124 is reenergized, causing the second electromagnet 1242 to engage the second magnetic block 1241; and the first electromagnet 1232 remains energized, locking the rocker arm 121. When the vehicle is lowered, the magnetic assembly at the corresponding height, selected based on image recognition, is deactivated, driving the baffle 122 to precisely rotate 90° to a horizontal position. When the vehicle is locked, the transmitter 31 is first deactivated, followed by the baffle 122. This adaptive height adjustment mechanism significantly improves vehicle compatibility and addresses the charging alignment challenges caused by differences in chassis heights across different vehicle models. This embodiment integrates the wireless charging transmitter 31 within the baffle 122 and utilizes the baffle 122 to extend horizontally from the vehicle body 12, achieving height adaptation of the wireless charging module 3 and physically integrating the floor lock and charging device into a single device. The control module directly manages ground lock posture control, charging start and stop, and vehicle sensing data, ensuring real-time synchronous billing of occupancy fees and charging fees, reducing equipment docking development costs and simplifying the payment process.
