Description

Technical Field

[0001] This invention relates to the field of vehicle charging technology, and in particular to a rotary charging device. Background Technology

[0002] In the operation and use of multi-level parking garages, the popularization of new energy vehicles has made charging support services an indispensable function of parking facilities. The integration of charging functions with parking is an important trend to improve the intelligence level of parking garages.

[0003] Currently, charging equipment in automated parking garages generally uses a fixed bracket structure, with the charging gun directly mounted on the parking tray. However, the charging port locations vary significantly between different brands and models of new energy vehicles; some models have the charging port on the left side of the vehicle, while others have it on the right. Because the vehicle's parking position on the tray is relatively fixed, it cannot be dynamically adjusted according to the specific location of the charging port, often resulting in a mismatch between the charging port and the charging gun bracket.

[0004] When the vehicle's charging port is aligned with the charging gun bracket, issues arise such as insufficient charging gun cable length and difficulty in plugging and unplugging. In severe cases, forcibly pulling the cable can cause physical damage to the charging equipment, such as cracked cable sheaths, loose connections, or internal short circuits, potentially even posing electrical safety hazards. In the automated mechanical operation environment of a multi-level parking garage, if operators need to manually adjust the charging gun position, it is not only inefficient and increases manpower burden, but also poses a collision risk due to the movement trajectory of mechanical parts, threatening personal safety.

[0005] Some technologies attempt to cover the charging needs on the left and right sides by manually adjusting the brackets or adding multiple sets of charging guns and brackets. The former is cumbersome to operate and lacks intelligent control, making it difficult to adapt to high-frequency usage scenarios; the latter significantly increases the equipment manufacturing cost, maintenance complexity and space occupancy rate, resulting in a decrease in the compactness of the layout of the multi-level parking garage, which cannot meet the actual needs of efficient, convenient and economical operation.

[0006] Therefore, there is an urgent need to develop a charging device that can dynamically adapt to the differences in the left and right positions of the charging ports of different car models. Summary of the Invention

[0007] The purpose of this invention is to provide a rotating charging device that can flexibly adapt to the differences in the left and right positions of the charging interface of different vehicle models, thereby improving charging safety and ease of operation.

[0008] To address the aforementioned technical problems, this invention provides a rotary charging device applied to an automated parking system. The charging device includes a charging unit, a swing arm unit, a rotation drive unit, a position detection unit, and a control unit. The charging unit is connected to one end of the swing arm unit, and the rotary drive unit is connected to the other end of the swing arm unit. The swing arm unit is also used to fix the cable. The rotary drive unit is fixed on the mounting base, and the mounting base is installed on one side of the vehicle pallet. The position detection unit and the rotation drive unit are respectively electrically connected to the control unit; The position detection unit is used to detect the location of the vehicle's charging port and transmit the detected position signal to the control unit; The control unit stores the position information of the charging unit and the correspondence between the target charging position. The control unit is used to control the rotation drive unit to drive the swing arm unit to rotate in the horizontal or vertical plane according to the correspondence and the position signal, so that the charging unit automatically switches to the target charging position corresponding to the charging port.

[0009] Furthermore, when the swing arm unit is not performing a charging action, it is positioned at a preset intermediate limit position above the vehicle carrier tray, so that the swing arm unit forms a physical block, restricting non-charging vehicles from entering the parking space. The intermediate limiting position is located above the vehicle pallet.

[0010] Furthermore, the charging device also includes a charging authorization triggering unit, which is electrically connected to the control unit; The control unit can control the rotation drive unit to drive the swing arm unit to rotate from the preset intermediate limit position only after receiving the instruction from the charging authorization trigger unit, so that the charging unit automatically switches to the target charging position.

[0011] Furthermore, the charging authorization triggering unit includes at least one of a QR code authorization unit and a reservation interaction unit; The QR code authorization unit is used for users to scan a code to generate a charging authorization signal. The QR code authorization unit is set on the swing arm unit or at the entrance of the automated parking garage. The reservation interaction unit is used to receive user reservation instructions, which include vehicle model and charging port location information.

[0012] Furthermore, the rotary drive unit includes a transmission mechanism and a rotary seat disposed on the mounting base, the rotary seat being connected to the transmission mechanism.

[0013] Furthermore, the transmission mechanism includes a motor, which is electrically connected to the control unit, and the output shaft of the motor is drively connected to the rotating base, so that the motor drives the rotating base to rotate.

[0014] Furthermore, the transmission mechanism includes a cylinder, which is electrically connected to the control unit. The piston rod of the cylinder is connected to the rotating seat, converting the extension and retraction motion of the cylinder into the rotational motion of the rotating seat.

[0015] Furthermore, the swing arm unit includes a swing rod and a vertical rod, the charging unit is connected to one end of the vertical rod, the other end of the vertical rod is connected to one end of the swing rod, and the other end of the swing rod is connected to the rotating seat.

[0016] Furthermore, the position detection unit includes a license plate recognition module, which is used to identify vehicle license plate information and match the corresponding vehicle model. Based on the vehicle model pre-stored data in the control unit, it determines the side of the vehicle body where the charging port is located, generates and transmits the position signal to the control unit, so that the rotation drive unit drives the swing arm unit to rotate to the corresponding charging position.

[0017] Furthermore, the charging device also includes a manual control unit, which is electrically connected to the control unit and is used to receive a manual trigger command from the user and transmit a signal to the control unit according to the trigger command, so that the control unit controls the rotation drive unit to drive the swing arm unit to rotate to the target charging position.

[0018] Furthermore, the charging device also includes a sound indicator unit, which is electrically connected to the control unit and is used to receive and recognize sound commands issued by the user and transmit the sound commands to the control unit, thereby causing the rotation drive unit to drive the swing arm unit to rotate to the corresponding charging position.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects: This invention, by setting up a rotatable swing arm unit and a charging unit, along with a position detection unit and a control unit, can automatically identify the side where the vehicle's charging port is located, thereby driving the swing arm unit to rotate in the horizontal or vertical plane, so that the charging unit can accurately switch to the target position corresponding to the charging port. This achieves adaptive adjustment of the charging position, eliminating the need for manual adjustment of the charging interface orientation, adapting to electric vehicles with different charging port positions, improving the automation and versatility of charging operations in multi-level parking garages, and meeting the usage requirements for compatible charging of multiple vehicle models.

[0020] Furthermore, the swing arm unit is positioned at the middle limit position above the vehicle carrier tray when not charging. The swing arm itself forms a physical blocking structure, which can effectively restrict non-charging vehicles such as fuel vehicles from occupying charging parking spaces, achieving the anti-occupancy function. No additional ground lock device is required, making the structure more streamlined. At the same time, the swing arm movement is controlled through multiple authorization triggering methods such as QR code authorization and mobile phone reservation. The swing arm can only be driven after obtaining a valid charging authorization, which improves the safety and management standardization. The overall device integrates automatic charging, parking space protection and intelligent authorization, making it more practical and more suitable for large-scale application in multi-level parking garages.

[0023] Based on the teachings of this specification, those skilled in the art can form new technical solutions by combining different implementation methods without creating technical contradictions. Such variations should be considered to fall within the protection scope of this application.

[0024] The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.

[0025] The invention is described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0026] like Figures 1 to 2 As shown, this embodiment provides a rotating charging device for use in a multi-level parking garage. The multi-level parking garage includes a vehicle carrying tray, which is used to carry vehicles and can be moved between different parking levels of the multi-level parking garage to realize the three-dimensional utilization of multi-level parking space.

[0027] Specifically, the charging device includes a charging unit 1, a swing arm unit, a rotation drive unit, a position detection unit, and a control unit.

[0028] The charging unit 1 is connected to one end of the swing arm unit, and the rotary drive unit is connected to the other end of the swing arm unit. The rotary drive unit is fixed on the mounting base 4, which is installed on one side of the vehicle carrier tray. The charging unit 1 is installed at the end of the swing arm unit and moves with the rotation of the swing arm unit, thereby enabling free switching of the charging interface in spatial position. The swing arm unit, as the load-bearing and transmission structure of the charging unit 1, receives instructions from the control unit to precisely control the rotation angle and direction of the swing arm unit, thereby driving the charging unit 1 to rotate to the target charging position. This ensures that the charging unit 1 reaches the side where the vehicle charging port is located by rotation, solving the problem that traditional fixed charging devices cannot adapt to the charging port positions of different vehicle models. The rotary drive unit provides power for the rotation of the swing arm unit, and the mounting base 4 provides a stable mounting foundation for the swing arm unit and the charging unit 1, allowing the overall structure to move synchronously with the vehicle carrier tray, adapting to the lifting and moving conditions of the automated parking system.

[0029] The position detection unit and the rotary drive unit are electrically connected to the control unit, forming a complete electronic control signal transmission link to support subsequent automatic control. The position detection unit detects the location of the vehicle's charging port and transmits the detected position signal to the control unit, providing a basis for the control unit's precise control, thereby eliminating manual judgment and adjustment and achieving automated adjustment.

[0030] The control unit stores the position information of the charging unit 1 and the correspondence between the target charging position. When the control unit receives the position signal from the position detection unit, it controls the rotation drive unit to drive the swing arm unit to rotate in the horizontal or vertical plane according to the correspondence and the position signal, so that the charging unit 1 automatically switches to the target charging position corresponding to the charging port, thereby enabling the charging device to meet the usage requirements of various vehicle models and various charging port positions.

[0031] Furthermore, when not performing a charging action, the swing arm unit is positioned at a preset intermediate limit position above the vehicle carrier tray, thus forming a physical obstruction and restricting non-charging vehicles from entering the parking space. The intermediate limit position is located above the vehicle carrier tray.

[0032] Specifically, when the swing arm unit is in the intermediate limit position, it is positioned horizontally above the vehicle tray parking area, forming a visible physical barrier in both the vertical and horizontal directions. Fuel-powered vehicles or vehicles that do not require charging will be physically blocked by the swing arm unit when entering the parking space, preventing them from entering smoothly. This effectively reserves charging spaces for electric vehicles that require charging, achieving precise management of parking space resources and preventing charging facilities from being occupied by vehicles without charging needs for extended periods. Compared to traditional parking lock solutions, this solution utilizes the swing arm unit of the charging device itself to also provide anti-occupancy functionality, eliminating the need for additional parking lock devices and reducing system complexity and construction costs.

[0033] In this embodiment, the swing arm unit is provided with a wiring channel inside, which is used to store and fix the wire. Specifically, the charging gun wire or power cord can be adapted according to the actual installation scenario of the charging unit 1.

[0034] In one embodiment, the charging unit 1 is positioned on the ground, and a charging gun cable is threaded through the swing arm unit. The charging gun cable moves synchronously with the rotation of the swing arm unit. During rotation, the swing arm unit constrains and protects the charging gun cable, preventing it from becoming tangled, pulled, or worn. It also prevents the charging gun from being accidentally stretched during insertion and removal, and from falling onto the vehicle tray or the ground if the charging gun is forgotten to be reinserted into the charging socket on the swing arm, thus reducing equipment damage and safety hazards.

[0035] In another embodiment, the charging unit 1 is mounted on the swing arm unit, and a power cable is run through the swing arm unit. The power cable is protected by the cable routing channel to reduce wear on the power cable during the rotation of the swing arm and extend its service life.

[0036] The two wiring layout methods described above can meet the installation layout requirements of different automated parking systems. At the same time, the swing arm unit can organize and protect the cables, reduce cable wear, and improve the stability and service life of the device.

[0037] In addition, cables located on the outside of the vehicle pallet can be wound up and unwound with the cable chain during the lifting or lateral movement of the vehicle pallet, further preventing the cables from getting tangled, pulled or worn during the movement of the vehicle pallet, making the device more reliable.

[0038] In this embodiment, the charging device further includes a charging authorization triggering unit, which is electrically connected to the control unit. The control unit, upon receiving an instruction from the charging authorization triggering unit, can control the rotation drive unit to drive the swing arm unit to rotate from the preset intermediate limit position, thereby automatically switching the charging unit 1 to the target charging position.

[0039] The charging authorization triggering unit adds an access control mechanism to the charging device in addition to physical anti-occupancy measures. The swing arm unit defaults to the intermediate limit position; only after an authorized electric vehicle user triggers the command can the swing arm unit begin to rotate. This effectively prevents unauthorized personnel from arbitrarily operating the charging device, protecting the safe and normal operation of the charging facilities, and further enhancing the controllability and orderliness of parking space management.

[0040] Furthermore, the charging authorization triggering unit includes at least one of a QR code authorization unit and a reservation interaction unit. The QR code authorization unit is used by the user to scan a QR code to generate a charging authorization signal. This unit is located on the swing arm unit or at the entrance of the automated parking garage. By placing the QR code authorization unit at the entrance of the automated parking garage, the user can complete the authorization before entering the garage, further improving passage efficiency. The reservation interaction unit is used to receive user reservation instructions, which include vehicle model and charging port location information. This allows the control unit to know the charging port location in advance and control the rotating power device to drive the charging unit 1 to the corresponding charging position, improving the convenience and efficiency of the charging process. The QR code authorization unit and the reservation interaction unit can be used independently or configured simultaneously to adapt to different user habits and management needs in different scenarios.

[0041] In practical use, the scanning authorization unit can use a QR code. After the user scans the QR code to complete identity verification or payment authorization via a mobile phone or other terminal, the scanning authorization unit sends a charging authorization signal to the control unit, triggering the swing arm unit to start rotating (equivalent to unlocking the swing arm unit, allowing the swing arm unit to perform subsequent rotating actions).

[0042] In this embodiment, the rotary drive unit includes a transmission mechanism and a rotating seat 5 mounted on the mounting base 4, the rotating seat 5 being connected to the transmission mechanism. The rotating seat 5 serves as the rotational support axis of the swing arm unit, providing a stable rotational foundation for the swing arm unit, enabling it to rotate smoothly and controllably around the rotating seat 5. The transmission mechanism provides the driving force for the rotation of the rotating seat 5. By appropriately selecting the type and specifications of the transmission mechanism, precise control of the rotational speed, output torque, and rotation angle of the rotating seat 5 can be achieved, thereby precisely controlling the charging unit 1 to reach the target charging position.

[0043] Furthermore, as one embodiment of the transmission mechanism, the transmission mechanism includes a motor, which is electrically connected to the control unit. The output shaft of the motor is drively connected to the rotating base 5, causing the motor to drive the rotating base 5 to rotate. The motor-driven method has advantages such as high control precision, fast response speed, and programmable rotation angle. The control unit sends speed and target rotation angle commands to the motor, and the motor's output shaft transmits the motor's rotational motion to the rotating base 5, thereby driving the swing arm unit to rotate to the target position. The electrical connection between the motor and the control unit allows the entire driving process to be precisely scheduled by the control unit, enabling smooth start-stop and precise positioning.

[0044] Furthermore, as another embodiment of the transmission mechanism, the transmission mechanism includes a cylinder, which is electrically connected to the control unit. The piston rod of the cylinder is connected to the rotating seat 5, converting the extension and retraction motion of the cylinder into the rotational motion of the rotating seat 5, thereby driving the swing arm unit to rotate. The cylinder-driven method has a simple structure and advantages such as large output force and rapid action.

[0045] In the specific implementation process, the transmission mechanism can adopt different driving methods according to different installation conditions, power requirements and cost budgets of the multi-level parking garage, so as to adapt to the actual use needs of multi-level parking garages of different sizes.

[0046] In this embodiment, the swing arm unit includes a swing rod 2 and a vertical rod 3. The charging unit 1 is connected to one end of the vertical rod 3, the other end of the vertical rod 3 is connected to one end of the swing rod 2, and the other end of the swing rod 2 is connected to the rotating seat 5.

[0047] Both the swing arm 2 and the upright arm 3 can be made of solid or hollow metal rods, such as steel pipes or aluminum alloy profiles, and can be fixed and installed by welding, bolting or snap-fitting.

[0048] When the rotating base 5 rotates, the support arm, composed of the swing rod 2 and the upright rod 3, rotates synchronously as a rigid structure, thereby driving the charging unit 1 to smoothly switch between the left and right charging positions. This multi-point support and torque transmission mechanism enhances the structural rigidity and stability of the charging unit 1 during rotation, enabling the charging unit 1 to be accurately positioned at the preset charging position and effectively resisting external disturbances.

[0049] In one specific embodiment, such as Figure 1As shown in the figure, a structural form in which the charging unit 1 rotates horizontally with the swing arm unit is illustrated. The swing arm unit rotates in the horizontal plane under the drive of the rotation drive unit, which can rotate the charging unit 1 to the target charging position corresponding to the left or right side of the vehicle charging port. It can adapt to the left and right orientation differences of the charging port of different models, and can realize the automatic adjustment of the charging unit 1 with the side where the charging port is located without the need for manual adjustment of the orientation of the charging interface.

[0050] In another specific embodiment, such as Figure 2 As shown in the figure, the charging unit 1 rotates vertically with the swing arm unit. The swing arm unit rotates in the vertical plane under the drive of the rotation drive unit, which can rotate the charging unit 1 to the target charging position corresponding to the left or right side of the vehicle charging port, adapting to the left and right orientation differences of the charging port of different models.

[0051] Both of the above rotation methods can achieve automatic adjustment between the charging unit 1 and the side where the charging port is located, meeting the usage requirements of automatic charging of multiple vehicle models in the multi-level parking garage.

[0052] In this embodiment, the position detection unit includes a license plate recognition module. The license plate recognition module is used to identify vehicle license plate information and match the corresponding vehicle model. Based on the vehicle model pre-stored data in the control unit, it determines the side of the vehicle body where the charging port is located, generates and transmits the position signal to the control unit, so that the rotation drive unit drives the swing arm unit to rotate to the corresponding charging position.

[0053] Specifically, the license plate recognition module can be implemented using a camera combined with image recognition algorithms. When a vehicle enters the vehicle carrier tray, the license plate recognition module queries a local or cloud database to match the vehicle brand and model corresponding to the license plate. The control unit locates the side of the vehicle where the charging port for that model is located based on a pre-stored vehicle model database, generates a position signal, and triggers the swing arm unit to rotate to the corresponding charging position, thereby further improving the automation level of the charging device and the user experience. The pre-stored vehicle model database can be remotely updated in the background to continuously incorporate new vehicle model data, effectively responding to the ever-increasing number of new models on the market.

[0054] In this embodiment, the charging device further includes a manual control unit electrically connected to the control unit. This manual control unit receives manual trigger commands from the user and transmits signals to the control unit according to the trigger commands. The control unit then controls the rotation drive unit to rotate the swing arm unit to the target charging position. The manual control unit provides a means of manual intervention for the charging device. In situations such as malfunctions in the automatic detection function, the vehicle model database not covering a specific model, or special charging needs of the user, the user can directly specify the target rotation direction and position of the swing arm unit through the manual control unit, effectively improving the applicability of the charging device in various non-standard situations. The manual control unit can take the form of physical buttons, a touchscreen, etc., and can be placed in a prominent and easily accessible location in the automated parking system for convenient manual operation by the user at any time.

[0055] The manual button device can take various forms, such as mechanical buttons, touch buttons, membrane switches, or capacitive sensing buttons, providing a clear and perceptible operating point that allows the user to actively control the device's operation. In a specific usage scenario, the manual control unit is at least one of a single-button button and a double-button button. The single-button button switches the left and right positions with each press, while the double-button button includes two buttons corresponding to the left and right charging positions, respectively. A single-button button allows for cyclical switching between two or more states using a single button. For example, each press of the button alternates the position of the lever 2 between the left and right charging positions. The advantage of this mode is its simplicity, reduced number of buttons, and suitability for scenarios with limited space or those pursuing a minimalist design. A double-button button uses two independent buttons, each corresponding to a specific operation or state. For example, one button is specifically used to control the lever 2 to rotate to the left charging position, while the other button controls it to rotate to the right charging position. The advantage of this mode is its intuitive operation, avoidance of accidental operation, and clear selection of the target position by the user.

[0056] Furthermore, the charging device also includes a sound indicator unit, which is electrically connected to the control unit and is used to receive and recognize sound commands issued by the user and transmit the sound commands to the control unit, thereby causing the rotation drive unit to drive the swing arm unit to rotate to the corresponding charging position.

[0057] In practical use, the voice indicator device can be placed anywhere at a vehicle charging location, allowing for selection of a suitable installation position based on the site environment. This facilitates the acquisition of voice commands issued by the user after parking, further enhancing the convenience and applicability of operation. The voice indicator unit includes a built-in microphone and a voice recognition processing module, which collects and recognizes the natural language commands issued by the user in real time. After capturing the user's voice information, the voice indicator unit recognizes it and converts it into a corresponding control signal, which is then transmitted to the control unit. The control unit then drives the swing arm unit to rotate to the corresponding target charging position.

[0058] In summary, this invention, by setting up a rotatable swing arm unit and a charging unit, in conjunction with a position detection unit and a control unit, can automatically identify the side where the vehicle's charging port is located, thereby driving the swing arm unit to rotate in the horizontal or vertical plane, enabling the charging unit to accurately switch to the target position corresponding to the charging port. This achieves adaptive adjustment of the charging position, eliminating the need for manual adjustment of the charging interface orientation, adapting to electric vehicles with different charging port positions, improving the automation and versatility of charging operations in multi-level parking garages, and meeting the usage requirements for compatible charging of multiple vehicle models.

[0059] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
