Description

Technical Field

[0001] This application relates to the field of automated parking equipment technology, and in particular to an automated parking equipment with mobile charging function. Background Technology

[0002] With the rapid development of electric vehicles, DC fast charging technology has become a key solution to meet users' needs for efficient charging due to its high power and short charging time characteristics.

[0003] Chinese invention patent application CN111546918A discloses a multi-parking-space mobile DC charging system. This system connects to a control device via a mobile client scanning a parking space's QR code. The system then moves the charging terminal from its initial position to above the designated parking space and releases the charging gun. After the user inserts the charging gun into the vehicle's charging port, the system completes the communication protocol connection and starts the DC charging host, supplying power to the vehicle via a conductive overhead rail. While this multi-parking-space mobile DC charging system enables flexible scheduling of the charging terminal across multiple parking spaces and effectively solves the charging problem when gasoline vehicles occupy charging spaces, the system requires an additional support structure to support the charging terminal, making installation somewhat cumbersome.

[0051] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0052] See Figures 1-9This invention illustrates a preferred embodiment of a multi-level parking system with mobile charging function, comprising:

[0053] The frame 1 has multiple parking areas 111, which are arranged sequentially along a first horizontal direction. Each parking area 111 has a lower parking space and an upper parking space.

[0054] The number of first vehicle carriers 2 is multiple. Each first vehicle carrier 2 is movably and vertically positioned at a parking area 111 of the frame 1, that is, each parking area 111 is provided with a first vehicle carrier 2.

[0055] The lifting drive mechanism 3 is a multiple lifting drive mechanism 3. Each lifting drive mechanism 3 is located at a parking area 111 of the frame 1. That is, each parking area 111 is equipped with a lifting drive mechanism 3. The output end of each lifting drive mechanism 3 is connected to a first vehicle platform 2 to drive the first vehicle platform 2 to switch between the lower parking space and the upper parking space.

[0056] Mobile charging pile 4 is mounted on frame 1 and can move along the first horizontal direction so that it can move between multiple parking areas 111.

[0057] The charging gun 5 is flexibly connected to the mobile charging station 4, allowing the charging gun 5 to move flexibly relative to the mobile charging station 4. The charging gun 5 is used to connect with the charging interface of the electric vehicle; and

[0058] The mobile drive mechanism 6 is mounted on the mobile charging pile 4 and is used to drive the mobile charging pile 4 to move along the frame 1.

[0059] This utility model discloses a three-dimensional parking system, comprising a frame 1, a first vehicle-carrying platform 2, a lifting drive mechanism 3, a mobile charging pile 4, a charging gun 5, and a mobile drive mechanism 6. When an electric vehicle needs charging, it is driven into the lower parking space of any vacant parking area 111. Then, the mobile driving mechanism 6 drives the mobile charging pile 4 to move to the corresponding parking area 111 and inserts the charging gun 5 into the electric vehicle's charging port. Finally, the lifting drive mechanism 3 drives the first vehicle-carrying platform 2 to lift the charging vehicle to the upper parking space, preventing the charging vehicle from occupying the lower parking space and allowing the lower parking space to be used by non-charging vehicles. This achieves separate parking for charging and non-charging vehicles, optimizing parking space utilization. The charging pile 4 can be flexibly scheduled and shared among multiple parking areas 111. Each parking area 111 controls the first vehicle-carrying plate 2 to switch between the lower parking space and the upper parking space through the lifting drive mechanism 3, so that a single parking area 111 can accommodate two cars. This not only solves the problems of charging spaces being occupied and power supply capacity being too large, but also increases the parking capacity per unit area. In addition, the mobile charging pile 4 can be movably set on the frame 1, thereby eliminating the need for an independent support structure for fixed installation. This makes the mobile charging pile 4 and the frame 1 form an integrated structure. By reusing the structure, the number of components is reduced, which not only simplifies the overall structure and reduces manufacturing costs, but also improves the ease of installation of the mobile charging pile, making the installation of the mobile charging pile more efficient.

[0060] See Figure 1 In one embodiment, the mobile charging pile 4 is located above the parking area 111. This arrangement of the mobile charging pile 4 above the parking area 111 makes full use of the vertical space, achieving high-level installation through the support of the frame 1, thus avoiding the occupation of ground space and affecting vehicle passage and parking.

[0061] See Figures 4-5 In one embodiment, the multi-level parking system with mobile charging function further includes:

[0062] Flexible charging cable 7, one end of which is electrically connected to charging gun 5, and the other end of flexible charging cable 7 is electrically connected to mobile charging pile 4.

[0063] A cable winding device 8 is mounted on the mobile charging pile 4. The output end of the cable winding device 8 is connected to the other end of the flexible charging cable 7. The output end of the cable winding device 8 rotates to wind or unwind the flexible charging cable 7. By setting up the flexible charging cable 7 and the cable winding device 8, where both ends of the flexible charging cable 7 are electrically connected to the charging gun 5 and the mobile charging pile 4 respectively, a flexible connection between the charging gun 5 and the mobile charging pile 4 is achieved. The cable winding device 8, mounted on the mobile charging pile 4 and connected to the flexible charging cable 7, allows for automatic winding or unwinding of the flexible charging cable 7 by rotating its output end in both directions. This allows the charging gun 5 to be stored near the mobile charging pile 4 when not charging, avoiding interference with car parking, and to be flexibly lowered to the charging interface of the electric vehicle when charging. This ensures the convenience and reliability of the charging operation, effectively solves the safety hazards and space occupation problems caused by the messy placement of the flexible charging cable 7, and simplifies the user operation process, improving the overall convenience and safety of the automated parking system.

[0064] In one embodiment, the cable retractor 8 is an electric cable retractor 8. By setting the cable retractor 8 as an electric cable retractor 8, the automated retraction and extension control of the flexible charging cable 7 is realized. This not only improves the convenience and reliability of the operation of storing and lowering the charging gun 5, but also ensures the stability and accuracy of the flexible charging cable 7 retraction and extension process through electric drive. At the same time, it reduces the need for manual intervention, further optimizes the user experience, and improves the safety and efficiency of the overall charging process.

[0065] Specifically, the take-up device 8 includes a take-up motor and a take-up reel. The take-up motor is mounted on the mobile charging station 4, and the output end of the take-up motor is connected to the take-up reel. The take-up reel can wind or unwind the flexible charging cable 7 as the output end of the take-up motor rotates.

[0066] In one embodiment, the mobile charging pile 4 has a cavity, and the cable retractor 8 is located inside the cavity. By integrating the cable retractor 8 into the cavity of the mobile charging pile 4, not only is the cable retractor 8 effectively protected from the influence of the external environment and the reliability of the multi-level parking equipment improved, but the overall spatial layout is also optimized to make the appearance neater. Furthermore, the built-in structure avoids the risk of interference from external components, thereby improving the protective performance and aesthetics of the multi-level parking equipment while ensuring the stability of the charging function.

[0067] In one embodiment, the lifting drive mechanism 3 is used to be electrically connected to a first power supply (not shown in the figure);

[0068] Both the mobile charging pile 4 and the mobile drive mechanism 6 are used for electrical connection to the second power supply (not shown in the figure). By connecting the lifting drive mechanism 3 to the first power supply and the mobile charging pile 4 and the mobile drive mechanism 6 to the second power supply, the electrical isolation between the power supply and charging function of the automated parking system is achieved. This ensures the reliability of the two systems operating independently without interference, avoids the impact of voltage fluctuations on the lifting drive mechanism 3 during high-power charging, and facilitates separate maintenance of each power supply module during the maintenance of the automated parking system. This improves the stability of the automated parking system, ensures charging quality, and optimizes the maintainability of the equipment.

[0069] See Figures 1-5 In one embodiment, the frame 1 includes:

[0070] Main frame 11, main frame 11 having multiple parking areas 111; and

[0071] The first guide rail 12 connects to the main frame 11, and the mobile charging pile 4 is movably mounted on the first guide rail 12. By setting the frame 1 as a main frame 11 with multiple parking areas 111 and the first guide rail 12 connecting the main frame 11, and movably mounting the mobile charging pile 4 on the first guide rail 12, flexible scheduling and precise positioning of the mobile charging pile 4 among multiple parking spaces are achieved. This fully utilizes the structure of the main frame 11 as the supporting foundation for the first guide rail 12 without the need for additional independent support structures. Furthermore, the cooperation between the first guide rail 12 and the mobile charging pile 4 enables a single mobile charging pile 4 to efficiently serve multiple parking spaces. At the same time, the setting of the first guide rail 12 ensures the stability and reliability of the movement of the mobile charging pile 4, thereby achieving the comprehensive effect of optimizing space utilization, improving charging efficiency, and reducing the cost of the multi-level parking equipment.

[0072] See Figure 9 In one embodiment, the first guide rail 12 has a guide groove 121;

[0073] The mobile charging pile 4 is equipped with a guide wheel 9, which is located within a guide groove 121. The output end of the mobile drive mechanism 6 is connected to the guide wheel 9, and the guide wheel 9 can move along the guide groove 121 as the output end of the mobile drive mechanism 6 rotates. In this way, through the constraint of the cooperation between the guide wheel 9 and the guide groove 121, the mobile charging pile 4 runs strictly along a predetermined trajectory, ensuring accurate positioning and avoiding deviation or jamming. At the same time, the mobile drive mechanism 6 directly drives the guide wheel 9, eliminating intermediate transmission links, which not only improves transmission efficiency but also simplifies the structure and reduces manufacturing costs.

[0074] It should be noted that the specific structure of the mobile drive mechanism 6 can be found in the patent document with publication number CN209320735U. The mobile drive mechanism 6 includes a mobile motor, which is mounted on the mobile charging pile 4. The output end of the mobile motor is connected to the guide wheel 9. When the output end of the mobile motor rotates forward or backward, the guide wheel 9 can reciprocate along the guide groove 121 as the output end of the mobile motor rotates.

[0075] In one embodiment, the moving drive mechanism 6 may further include a gear mechanism, wherein the driving gear of the gear mechanism is connected to the output end of the moving motor, and the driving gear can rotate with the output end of the moving motor; the driven gear of the gear mechanism is connected to the guide wheel 9, and the guide wheel 9 can move along the guide groove 121 as the driven gear rotates.

[0076] In one embodiment, the first guide rail 12 is located above the main frame 11. Thus, by placing the first guide rail 12 above the main frame 11, the mobile charging pile 4 operates in a high-level space, avoiding the risk of interference with ground vehicles or personnel, fully utilizing the unused upper space of the automated parking system, and the high-level arrangement of the first guide rail 12 naturally forms a suspension support structure for the mobile charging pile 4, eliminating the need for additional suspension devices. This optimizes space utilization, simplifies the overall structural layout, and improves the operational safety of the automated parking system.

[0077] It should be noted that the electrical connection between the mobile charging pile 4 and the second power supply can be referred to in the patent document with announcement number CN209320735U. The first guide rail 12 is provided with a conductive cable (not shown in the figure), which is electrically connected to the second power supply. The conductive cable extends along the first horizontal direction, and the conductor cable is provided with electrically conductive contact parts at even intervals at the position corresponding to the parking area 111 along the first horizontal direction.

[0078] The first guide rail 12 has a contact groove at the position corresponding to the energized contact part;

[0079] A conductive block is telescopically connected to the guide wheel 9. The conductive block is electrically connected to the flexible charging cable 7. In this embodiment, a spring can be provided between the guide wheel 9 and the conductive block. The two ends of the spring abut against the conductive block and the guide wheel 9, respectively. The spring stores elastic potential energy. When the guide wheel 9 moves to the contact groove, the spring force presses against the conductive block, and the conductive block extends out from the guide wheel 9, so that the conductive block contacts the energized contact part in the first guide rail 12 to realize power transmission. When the guide wheel 9 moves away from the contact groove, the groove surface of the first guide rail 12 presses against the conductive block, and the conductive block retracts into the guide wheel 9, ensuring that the guide wheel 9 can move smoothly along the guide groove 121.

[0080] See Figure 1 as well as Figures 4-5In one embodiment, the multi-level parking system with mobile charging function further includes:

[0081] There are multiple positioning QR codes 10, and each positioning QR code 10 is set at a corresponding position in a parking area 111 of the main frame 11. That is, each parking area 111 corresponds to one positioning QR code 10.

[0082] The control device is electrically connected to the lifting drive mechanism 3, the mobile charging pile 4, and the mobile drive mechanism 6. The control device is configured to: when the user terminal scans any positioning QR code 10, control the mobile charging pile 4 to move above the parking area 111 corresponding to the positioning QR code 10; when the charging gun 5 is electrically connected to the electric vehicle and the electric vehicle is unoccupied, control the lifting drive mechanism 3 to drive the corresponding first vehicle carrier 2 to move from the lower parking space to the upper parking space. By setting up positioning QR codes 10 at corresponding positions in each parking area 111 of the main frame 11 and configuring control devices, intelligent charging scheduling management is achieved. The control devices accurately control the mobile charging pile 4 to move above the corresponding parking area 111 based on the positioning QR code 10 information scanned by the user terminal. When the charging gun 5 is detected to be connected to the electric vehicle and the vehicle is unattended, the lifting drive mechanism 3 is automatically controlled to move the first vehicle platform 2 from the lower parking space to the upper parking space. This solution, through the coordinated cooperation of QR code positioning and control devices, not only achieves accurate positioning and automated scheduling of the mobile charging pile 4, improving charging efficiency, but also ensures the safety of the charging process. At the same time, the intelligent control of automatic lifting in unattended states optimizes the user experience. Overall, it achieves the effects of improving the automation level of the multi-level parking equipment, ensuring operational safety, and enhancing user convenience.

[0083] It should be noted that the connection between the charging gun 5 and the electric vehicle, and the vehicle being unmanned, can be achieved through the following technical means:

[0084] Set up a charging connection detection module: Set a pressure sensor or micro switch on plug 5 of the charging gun to detect the physical connection status with the charging interface of the electric vehicle.

[0085] Set up a vehicle personnel detection system: install a millimeter-wave radar on the top of parking area 111 to monitor vital signs (breathing / heartbeat) inside the vehicle in real time; or, deploy an infrared thermal imaging sensor array to scan the heat radiation distribution inside the vehicle; or, use an on-board weight sensor to compare the weight change of the first vehicle platform 2 before and after charging; or, set up a panoramic camera for image recognition.

[0086] Control logic implementation:

[0087] When the charging gun 5 connection signal and the vehicle BMS communication are both valid, and no personnel presence signal is detected for 30 consecutive seconds, the lifting control is triggered.

[0088] See Figure 8 In one embodiment, the multi-level parking system with mobile charging function further includes:

[0089] There are multiple identification tags 20, and each identification tag 20 is set at the position corresponding to the first guide rail 12 and the parking area 111.

[0090] A tag reader 30 is installed on the mobile charging pile 4 and electrically connected to a control device. When the tag reader 30 reads the corresponding identification tag 20, the control device controls the mobile charging pile 4 to stop moving. Thus, when the tag reader 30 detects the target identification tag 20, the control device immediately brakes the mobile charging pile 4, effectively stopping it upon reaching the target parking area 111. This solution, through a dual positioning mechanism of physical tags and electronic identification, achieves millimeter-level positioning accuracy of the mobile charging pile 4's moving endpoint, avoiding the cumulative error problem of traditional position sensors. It also ensures the real-time performance and reliability of the braking response through direct hardware signal interaction, while simplifying the algorithm complexity of the control device. This improves parking positioning accuracy while reducing the debugging and maintenance costs of the automated parking system, ultimately achieving rapid and accurate alignment between the mobile charging pile 4 and the parking area 111.

[0091] It should be noted that the control device in this embodiment uses a device that can achieve the above functions in the existing market. The internal circuit and the control circuit between each structure can be implemented by those skilled in the art through programming. It is common knowledge in the art. It is only used and not improved. Therefore, this embodiment will not explain the control method and circuit connection in detail.

[0092] See Figures 1-3 In one embodiment, the lifting drive mechanism 3 includes:

[0093] Lifting motor 31 is mounted on the main frame 11;

[0094] The main drive sprocket 32 ​​is connected to the output shaft of the lifting motor 31, and the main drive sprocket 32 ​​can rotate with the output shaft of the lifting motor 31.

[0095] The transmission is from sprocket 33;

[0096] The transmission chain 34 is rotatably sleeved between the main transmission sprocket 32 ​​and the driven transmission sprocket 33.

[0097] The main drive shaft 35 is rotatably mounted on the main frame 11. The main drive shaft 35 extends along the first horizontal direction, and the first end of the main drive shaft 35 is inserted into the center hole of the drive sprocket 33.

[0098] The first drive sprocket 36 is sleeved on the second end of the main drive shaft 35 and can rotate with the main drive shaft 35.

[0099] The second drive sprocket 37 is sleeved on the first end of the main drive shaft 35 and can rotate with the main drive shaft 35.

[0100] The drive shaft (not shown in the figure) is rotatably mounted on the main frame 11. The drive shaft is parallel to the main drive shaft 35 and is spaced apart from the main drive shaft 35 along the second horizontal direction.

[0101] The first drive sprocket (not shown in the figure) is sleeved on the first end of the drive shaft and can rotate with the drive shaft.

[0102] The second drive sprocket 38 is sleeved on the second end of the drive shaft and can rotate with the drive shaft.

[0103] The main drive chain 39 is rotatably mounted between the first main drive sprocket 36 and the second driven slave sprocket 38.

[0104] A drive chain (not shown in the figure) is rotatably sleeved between the second drive master sprocket 37 and the first drive slave sprocket.

[0105] Two first lifting chains 310 are spaced apart along the second horizontal direction. The upper ends of the two first lifting chains 310 are connected to the drive main chain 39, and the lower ends of the two first lifting chains 310 are connected to the first vehicle platform 2.

[0106] Two second lifting chains 320 are spaced apart along a second horizontal direction. The second lifting chains 320 and the first lifting chain 310 are spaced apart along a first horizontal direction. The upper ends of the two second lifting chains 320 are connected to the drive chain, and the lower ends of the two second lifting chains 320 are connected to the first vehicle platform 2. That is, there are a total of four lifting chains, which are respectively connected to the four corners of the first vehicle platform 2.

[0107] Thus, the lifting motor 31 is mounted on the main frame 11 and drives the main drive sprocket 32 ​​to rotate via its output shaft. The main drive sprocket 32 ​​drives the driven sprocket 33 to rotate synchronously via the drive chain 34. The driven sprocket 33 drives the main drive shaft 35 to rotate, and the first drive sprocket 36 and the second drive sprocket 37 at both ends of the main drive shaft 35 rotate synchronously accordingly. The first drive sprocket 36 drives the second drive sprocket 38 to rotate via the drive chain 39, while the second drive sprocket 37 drives the first drive sprocket to rotate via the drive chain, thereby causing the driven shaft, which is parallel to the main drive shaft 35, to rotate synchronously. The first drive sprocket and the second drive sprocket... The sprocket 38 forms a closed-loop transmission system through the driving main chain 39 and the driving slave chain respectively; the upper ends of the four lifting chains (including two first lifting chains 310 spaced apart along the second horizontal direction and two corresponding second lifting chains 320) are respectively connected to the driving main chain 39 and the driving slave chain, and the lower ends are connected to the four corners of the first vehicle platform 2. The rotational motion is converted into vertical lifting motion through chain transmission, so as to realize the smooth lifting of the first vehicle platform 2. The first horizontal direction and the second horizontal direction are perpendicular to each other to form a spatial transmission layout. The entire lifting drive mechanism 3 realizes the bidirectional lifting control of the first vehicle platform 2 through the forward and reverse rotation of the lifting motor 31.

[0108] See Figure 1 , Figure 6 and Figure 7 In one embodiment, the multi-level parking equipment is a horizontal lifting multi-level parking equipment. In this case, there are three parking areas, and the lower parking space in the middle parking area is a passing parking space.

[0109] Multi-level parking systems with mobile charging capabilities also include:

[0110] The second guide rail 40 extends along the first horizontal direction;

[0111] There are two second carrier plates 50. Each second carrier plate 50 is equipped with a wheel 60 at its bottom. The wheel 60 can be movably engaged with the second guide rail 40.

[0112] Two driving drive units 70 are provided, each mounted on a corresponding second vehicle carrier 50. Each driving drive unit 70 drives the wheels 60 on the corresponding second vehicle carrier 50 to move along the second guide rail 40. Thus, since the lower parking space in the middle of the three parking areas is a yielding space, when a vehicle is parked in the lower parking space of either of the two adjacent parking areas and a vehicle in the upper parking space needs to retrieve its vehicle, the driving drive unit 70 on the second vehicle carrier 50 of the lower parking space drives the wheels 60 to rotate, moving the second vehicle carrier 50 and the vehicle on it along the second guide rail 40 to the yielding space. This frees up space for the first vehicle carrier of the upper parking space to descend to its original position in the lower parking space.

[0113] It should be explained that there are two second guide rails 40, and the two second guide rails 40 are set apart along the second horizontal direction;

[0114] Each of the second vehicle platforms 50 has at least four wheels 60 at its bottom. Two of the wheels 60 are engaged with one of the second guide rails 40, and the other two wheels 60 are engaged with another second guide rail 40. The driving device 70 is used to drive the four wheels 60 to rotate.

[0115] It should be noted that the specific structure of the driving drive device 70 can be referenced from existing horizontal lifting three-dimensional parking equipment, and will not be described in detail here.

[0116] The working principle of this utility model's multi-level parking system is as follows:

[0117] After the car owner parks the electric vehicle in the lower parking space of parking area 111, the car owner connects to the control device by scanning the positioning QR code 10 with a mobile terminal. The control device sends a positioning movement command to the mobile drive mechanism 6.

[0118] When the mobile charging pile 4 moves above the corresponding parking area 111, the control device sends a release command for the flexible charging cable 7 to the cable retractor 8.

[0119] The car owner inserts the charging gun 5 into the charging port of the electric vehicle. The mobile charging pile 4 interacts with the electric vehicle through the charging protocol. After the power supply requirements are met, the control device sends a start command to the second power supply. The second power supply is started to transmit electrical energy to the charging gun 5 through the conductive cable to charge the electric vehicle.

[0120] When the charging gun 5 is detected to be connected to the electric vehicle and the vehicle is unmanned, the lifting drive mechanism 3 is controlled to move the first vehicle platform 2 from the lower parking space to the upper parking space.

[0121] After charging is complete, the lifting drive mechanism 3 moves the first vehicle platform 2 from the upper parking space to the lower parking space. The car owner stops charging by operating the mobile phone. The car owner unplugs the charging gun 5 from the charging interface. The control device sends a command to the cable retraction device 8 to retract the flexible charging cable 7, realizing the automatic retraction of the charging gun 5, and the mobile charging pile 4 moves to the initial position.
