Description

Technical Field

[0001] This application relates to the field of automotive charging technology, and in particular to a dual-purpose charging gun and charging system. Background Technology

[0002] In the current field of electric vehicle charging technology, the design of charging equipment mainly falls into two categories: manual charging guns that rely entirely on manual operation, and fully automated charging systems that integrate the charging gun head with a robotic arm. However, both of these models have significant technical limitations. In the mainstream automated charging solutions currently on the market, the charging gun head is usually rigidly integrated into the end of the posture adjustment mechanism, forming a fixed integrated structure with the robotic arm. While this structure enables the robotic arm to drive the gun head for automatic insertion and removal, it does not meet national standards, particularly lacking necessary safety locking mechanisms such as latches, thus failing to meet the basic need for manual insertion and removal of the charging gun. More importantly, existing technical solutions suffer from a serious deficiency in functional simplification. All charging gun products either only support manual operation or rely entirely on the robotic arm for automatic insertion and removal, with no functional compatibility between the two. This technological fragmentation leads to a dilemma for users: when manual intervention or emergency charging is required, the automated charging system does not offer a manual operation option; while when automated charging is needed, the manual charging gun cannot work in conjunction with the robotic arm system. Therefore, existing technologies cannot meet the application requirements of both national standards and manual insertion / removal by personnel, while also being able to be seamlessly integrated with robotic arm systems to achieve automatic insertion / removal. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this application provides a dual-purpose charging gun and charging system to solve the problem that existing charging guns cannot simultaneously meet the needs of automatic plugging and unplugging by robotic arms and manual plugging and unplugging.

[0004] The above-mentioned objectives of this application are mainly achieved through the following technical solutions: A dual-purpose charging gun, the dual-purpose charging gun comprising: The gun body has an internal cavity, and the gun body is equipped with an electrical connection cable and a gun head. The gun body also has a connection area for connecting to a robotic arm and a gripping area for manual operation. A connector is rotatably disposed within the cavity. A hook is provided at the first end of the connector, and the hook extends to the outside of the cavity. When the connector rotates, it can hook onto or detach from the charging port. A first control component is connected to the gripping area and is used to drive the connector to rotate. The first control component is fixedly connected to the connector and has an operating end extending out of the cavity. A second control component is connected to the connector. The second control component has a retractable drive end that can be abutted against the inner wall of the gun body to drive the connector to rotate.

[0005] In an optional embodiment, the dual-purpose charging gun further includes a controller electrically connected to the second control component and controlling the extension and retraction of the drive end.

[0006] In an optional embodiment, the dual-purpose charging gun further includes a micro switch electrically connected to the controller. The micro switch is disposed in the cavity of the gun body, and rotation of the connector can trigger the micro switch.

[0007] In an optional embodiment, the micro switch includes a normally closed interface and a normally open interface, the normally closed interface being connected to the cable and the normally open interface being connected to the controller.

[0008] In an optional embodiment, the gun body is provided with a first baffle and a second baffle, the first baffle being arranged at intervals below the operating end, and the second baffle being arranged at intervals below the second control component.

[0009] In an optional embodiment, a first reset part is provided between the first baffle and the operating end, and a second reset part is provided in the second control component to drive the driving end to reset.

[0010] In an optional embodiment, the gun body is provided with an end cap made of ferromagnetic material on the side away from the connection area, the end cap being used to magnetically connect the connection end of the robotic arm.

[0011] In an optional embodiment, the end cap is provided with at least two positioning holes, which are used to engage with the connecting end of the positioning robotic arm.

[0012] In an optional embodiment, the gun body is provided with a boss for supporting the drive end.

[0013] Based on the same inventive concept, this application also provides a charging system, which includes the dual-purpose charging gun as described above.

[0014] Compared with the prior art, the advantages of this application are: The dual-purpose charging gun of this application includes a gun body, a connector, a first control component, and a second control component. The gun body has an internal cavity and is equipped with an electrically connected cable and a gun head. The gun body also has a connection area for connecting to a robotic arm and a gripping area for manual operation. The connector is rotatably disposed within the cavity, and a hook is provided at its first end, extending outside the cavity. The connector can hook onto or detach from the charging port when rotated. The first control component is connected to the gripping area and is used to drive the connector to rotate. The first control component is fixedly connected to the connector and has an operating end extending outside the cavity. The second control component is connected to the connector and has a retractable driving end that can abut against the inner wall of the gun body to drive the connector to rotate.

[0015] This dual-purpose charging gun features a rotatable connector inside the gun body. The hook of the connector can extend to the outside of the cavity to hook or detach from the charging port. This not only meets the national standard requirements for safety locking mechanisms such as charging gun hooks, but more importantly, through the coordinated action of the first and second control components, it achieves seamless switching between manual operation and automatic control by the robotic arm.

[0016] When manual operation is required, the first control component on the gripping area drives the connector to rotate, and the operating end extends outside the cavity to facilitate direct force application by the user. When automatic operation of the robotic arm is required, the retractable drive end of the second control component generates a reaction force by being mounted on the gun body, driving the connector to complete the rotation action. Both modes share the same hook mechanism, avoiding the single-function defect of traditional solutions.

[0017] This dual-purpose charging gun employs a compound motion combining lever rotation and push-reaction. The connector, as the core transmission component, achieves precise rotational control within the cavity. The hook's motion trajectory is meticulously designed to ensure reliable mechanical locking with the charging port during insertion and removal. The first control component uses a direct drive method, converting the linear displacement of the operating end into the angular displacement of the connector, resulting in intuitive operation and high force transmission efficiency. The second control component utilizes the push-reaction principle; when the driving end extends or retracts, it rests against the inner wall of the gun body, using the inner wall as a reaction fulcrum to drive the connector's rotation. This avoids the problem of traditional automatic charging guns requiring rigid fixation to a robotic arm, allowing the gun body to exist independently of the robotic arm, only cooperating with it when needed. This not only improves the reliability of the mechanism but also greatly simplifies the control complexity of the robotic arm.

[0018] When users choose manual charging, they simply hold the grip area of ​​the charging gun and easily complete the plugging and unplugging action by operating the control terminal of the first control component. The entire process is no different from traditional manual charging guns, conforming to user operating habits. When automatic charging is required, the robotic arm connects to the charging gun through the connection area. The second control component, under the command of the control system, drives the connector to complete the hooking or unhooking action, achieving fully automatic plugging and unplugging. It is particularly noteworthy that the two working modes can be freely switched. Users can interrupt the automatic process and switch to manual operation at any time, or switch back to automatic mode if manual operation fails. This seamless switching capability greatly improves the reliability and emergency handling capability of the charging equipment. In addition, because the charging gun and the robotic arm adopt a non-fixed connection method, when automatic charging is not required, the charging gun can be completely detached from the robotic arm and work independently. This solves the technical problem of the charging head being fixed to the robotic arm in the prior art, making it impossible to manually remove.

[0019] This technical solution not only solves the incompatibility issue between manual and automatic charging functions mentioned in the background technology, but also ensures charging safety and reliability through a standard-compliant hook structure. It retains the flexibility and user habits of manual operation while possessing the convenience and precision of automatic operation. This greatly expands the application scenarios of charging equipment, enabling it to adapt to various environmental needs. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0023] like Figure 1 As shown, Figure 1 This is a cross-sectional view of a dual-purpose charging gun provided in an embodiment of this application; a dual-purpose charging gun includes a gun body 100, a connector 200, a first control component 300, and a second control component 400, wherein: like Figure 1 As shown, the gun body 100 has an internal cavity, and the gun body 100 is provided with an electrical connection cable 101 and a gun head 102. The gun body 100 is provided with a connection area for connecting to a robotic arm and a gripping area for manual operation.

[0024] like Figure 1 As shown, the gun body 100 serves as the main structure of the entire device. The gun body 100 has a precisely designed cavity structure inside, which not only provides installation space for various moving parts but also protects the internal mechanisms from external environmental influences. The gun body 100 integrates the electrical connection cable 101 and the gun head 102, ensuring stable power transmission performance during frequent plugging and unplugging. The gun body 100 has two functional areas on its exterior: a connection area for connecting to the robotic arm uses a standardized interface, allowing for quick docking with mainstream industrial robotic arms on the market; the grip area for manual operation is ergonomically optimized, with a non-slip texture and grooves conforming to the palm's curve, providing users with a comfortable grip and precise operational control.

[0025] like Figure 1 As shown, the connector 200 is rotatably disposed in the cavity. The first end of the connector 200 is provided with a hook 201, which extends to the outside of the cavity. When the connector 200 rotates, it can hook onto or detach from the charging port.

[0026] As a core transmission component, the connector 200 is rotatably mounted within the cavity of the gun body 100 via a precision bearing or bushing structure, ensuring smooth rotation and low frictional loss. The first end of the connector 200 extends to the outside of the gun body 100 and is equipped with a hook 201. The hook 201 can be made of high-strength alloy material, and its shape and size conform to the corresponding interface requirements, enabling it to hook and lock when inserted into the charging port, preventing accidental dislodgement. The movement trajectory of the hook 201 is precisely calculated and arranged; when the connector 200 rotates, the hook 201 moves along a preset arc path, achieving reliable connection and separation with the charging port locking mechanism.

[0027] In a specific implementation, the connector 200 can be a one-piece molded metal component or a multi-part assembly structure. The multi-part structure can achieve the adaptive adjustment function of the hook 201 through elastic elements to adapt to the slight size differences of different charging ports and improve the versatility and compatibility of the device.

[0028] like Figure 1 As shown, a first control component 300 is connected to the gripping area and is used to drive the connector 200 to rotate. The first control component is fixedly connected to the connector 200 and has an operating end 301 extending out of the cavity.

[0029] The first control component 300 is set for manual operation. It is connected to the grip area of ​​the gun body 100 via a fixed bracket or embedded mounting, allowing the user to naturally access the operating end 301 while holding the gun body 100. The first control component and the connecting component 200 are rigidly connected or connected by gear transmission to ensure precise force transmission and synchronous movement. The operating end 301 extends outside the cavity and can be shaped as a button, trigger, or knob. The user only needs to apply moderate force to drive the connecting component 200 to complete the rotation action through leverage.

[0030] like Figure 1 As shown, in actual arrangement, the surface of the operating end 301 can also be provided with anti-slip texture and tactile feedback structure. When the hook 201 completes the hooking or unhooking action, the user can perceive clear operation feedback through touch.

[0031] The second control component 400 is connected to the connector 200. The second control component 400 has a retractable drive end 401, which can be abutted against the inner wall of the gun body 100 to drive the connector 200 to rotate.

[0032] like Figure 1As shown, the second control component 400 is designed for automatic control mode and achieves collaborative work with the robotic arm through a non-contact drive method. The second control component 400 can be mounted on the connector 200 via a fixed base. The drive end 401 can be in the form of an electric push rod, a pneumatic piston, or an electromagnetic actuator, etc. The extension and retraction movement of the drive end 401 is precisely controlled by the robotic arm's control system. When automatic insertion and removal are required, the drive end 401 extends under the action of a control signal and rests against the inner wall of the gun body 100. Using the inner wall as a reaction fulcrum, the connector 200 is driven to rotate through the lever principle, thereby enabling the hook 201 to complete the hooking or disengaging action.

[0033] In practical implementation, a wear-resistant bushing can be installed at the corresponding position on the inner wall of the gun body 100 to ensure that the drive end 401 will not damage the gun body 100 during the pushing process. The second control component 400 can also be equipped with a position sensor and a force feedback device to monitor the movement status and force conditions of the hook 201 in real time. When abnormal resistance is encountered, the action can be stopped in time to prevent equipment damage or safety accidents. This not only achieves the precision of automatic control but also ensures safe isolation from the manual operation mode. The two modes can work independently without interfering with each other.

[0034] like Figure 1 As shown, this dual-purpose charging gun demonstrates excellent flexibility and reliability during actual operation. When the user chooses manual operation, they hold the gun body 100 in the gripping area and operate the first control component 300's operating end 301. Through force transmission and amplification, the connecting piece 200 rotates, causing the hook 201 to hook or disengage. The entire process is smooth and natural, consistent with the operating experience of a traditional manual charging gun. When automatic operation is required, the robotic arm grasps the gun body 100 through the connecting area. The control system sends a command to the second control component 400, and the driving end 401 extends and rests on the inner wall of the gun body 100. The reaction force drives the connecting piece 200 to rotate, automatically locking or releasing the hook 201. The two operating modes can be seamlessly switched. The user can interrupt the automatic process and switch to manual operation at any time, or switch to automatic mode when encountering difficulties in manual operation. This solves the problem of incompatibility between manual and automatic functions in existing technologies and also ensures the safety and reliability of the charging process.

[0035] In an optional embodiment, the dual-purpose charging gun of this application includes a gun body 100, a connector 200, a first control component 300, and a second control component 400. The gun body 100 has an internal cavity, and the gun body 100 is provided with an electrically connected cable 101 and a gun head 102. The gun body 100 has a connection area for connecting to a robotic arm and a gripping area for manual operation. The connector 200 is rotatably disposed within the cavity, and a hook 201 is provided at its first end, extending outside the cavity. When the connector 200 rotates, it can hook onto or detach from the charging port; a first control component 300 is connected to the grip area and is used to drive the connector 200 to rotate. The first control component is fixedly connected to the connector 200 and has an operating end 301 extending out of the cavity; a second control component 400 is connected to the connector 200 and has a retractable drive end 401. The drive end 401 can be abutted against the inner wall of the gun body 100 to drive the connector 200 to rotate.

[0036] The dual-purpose charging gun has a rotatable connector 200 inside the gun body 100. The hook 201 of the connector 200 can extend to the outside of the cavity to hook or detach from the charging port. This not only meets the national standard requirements for safety locking mechanisms such as charging gun hooks, but more importantly, through the coordinated action of the first control component 300 and the second control component 400, it achieves seamless switching between manual operation and automatic control by the robotic arm.

[0037] When manual operation is required, the first control component 300 on the gripping area drives the connector 200 to rotate, and the operating end 301 extends out of the cavity to facilitate direct force application by the user. When automatic operation of the robotic arm is required, the retractable drive end 401 of the second control component 400 generates a reaction force by being mounted on the gun body 100, which drives the connector 200 to complete the rotation action. The two modes share the same hook mechanism, avoiding the single-function defect of traditional solutions.

[0038] This dual-purpose charging gun employs a composite motion combining lever rotation and push-reaction. The connector 200, as the core transmission component, achieves precise rotation control within the cavity. The motion trajectory of the hook 201 is meticulously designed to ensure reliable mechanical locking with the charging port during insertion and removal. The first control component 300 uses a direct drive method, converting the linear displacement of the operating end 301 into the angular displacement of the connector 200, resulting in intuitive operation and high force transmission efficiency. The second control component 400 utilizes the push-reaction principle; when the driving end 401 extends or retracts, it presses against the inner wall of the gun body 100, using the inner wall as a reaction fulcrum to push the connector 200 to rotate. This avoids the problem of traditional automatic charging guns requiring rigid fixation to a robotic arm, allowing the gun body 100 to exist independently of the robotic arm, only cooperating with it when needed. This not only improves the reliability of the mechanism but also greatly simplifies the control complexity of the robotic arm.

[0039] When the user chooses manual charging, they only need to hold the grip area of ​​the gun body 100 and easily complete the plugging and unplugging action by operating the operating end 301 of the first control component 300. The whole process is no different from that of a traditional manual charging gun, which conforms to the user's operating habits. When automatic charging is required, the robotic arm connects to the gun body 100 through the connection area. Under the command of the control system, the second control component 400 drives the connector 200 to complete the hooking or unhooking action, realizing fully automatic plugging and unplugging. It is particularly noteworthy that the two working modes can be switched freely. The user can interrupt the automatic process and switch to manual operation at any time, or switch to automatic mode if manual operation fails. This seamless switching capability greatly improves the reliability and emergency handling capability of the charging equipment. In addition, since the gun body 100 and the robotic arm adopt a non-fixed connection method, when automatic charging is not required, the gun body 100 can be completely detached from the robotic arm and work independently. This solves the technical problem in the prior art where the gun head 102 is fixed to the robotic arm as one piece, making it impossible to remove manually.

[0040] This technical solution not only solves the incompatibility issue between manual and automatic charging functions mentioned in the background technology, but also ensures charging safety and reliability through the standard-compliant hook 201 structure. It retains the flexibility and user habits of manual operation while possessing the convenience and precision of automatic operation. This greatly expands the application scenarios of charging equipment, enabling it to adapt to various environmental needs.

[0041] In an optional embodiment, the dual-purpose charging gun further includes a controller electrically connected to the second control component 400 and controlling the extension and retraction of the drive end 401.

[0042] This controller, through precise timing control, can dynamically adjust the extension stroke and force of the drive end 401 of the second control component 400 based on the movement state of the robotic arm and the actual position of the charging port. During actual operation, the controller receives coordinated commands from the robotic arm control system and, combined with built-in sensor data, determines the relative position of the hook 201 and the charging port in real time, thereby triggering the extension and retraction of the drive end 401 at the optimal moment. This not only significantly improves the success rate and accuracy of automatic insertion and removal but also adapts to charging needs under different environmental conditions. For example, it automatically increases the driving force in low-temperature environments or immediately stops the operation and issues an alarm when abnormal resistance is detected, effectively preventing equipment damage and safety accidents.

[0043] like Figure 1 As shown, in an optional embodiment, the dual-purpose charging gun further includes a micro switch 501 electrically connected to the controller. The micro switch 501 is disposed in the cavity of the gun body 100, and the micro switch 501 can be triggered by the rotation of the connector 200.

[0044] The micro switch 501 provides crucial status monitoring and safety protection functions for the dual-purpose charging gun. Installed within the cavity of the gun body 100, the micro switch 501 accurately presses down the contact of the micro switch 501 when the connector 200 rotates to a preset angle, generating a clear status signal. This enables real-time monitoring of the hook 201's movement status. Whether in manual or automatic control mode, the system can accurately determine whether the hook 201 has completed its hooking or disengaging action. During automatic charging, the signal feedback from the micro switch 501 helps the controller confirm successful operation, preventing charging interruptions or safety hazards due to mechanical failures. More importantly, this mechanical status detection method boasts extremely high reliability and anti-interference capabilities, unaffected by changes in the electromagnetic environment, ensuring accurate status information under various complex operating conditions.

[0045] In an optional embodiment, the micro switch 501 includes a normally closed interface and a normally open interface, the normally closed interface being connected to the cable 101 and the normally open interface being connected to the controller.

[0046] The micro switch 501 employs a dual circuit with both normally closed and normally open interfaces. The normally closed interface is directly connected in series in the main power supply circuit of cable 101, forming a hardware-level safety interlock. When the hook 201 is not fully engaged, the normally closed contact remains open, fundamentally cutting off the output of high-voltage power and preventing potential safety accidents caused by charging in an unlocked state. The normally open interface connects to the controller to provide status signals and enable intelligent control at the software level. This dual protection meets the stringent requirements of electrical safety standards and achieves a reliable combination of hardware protection and software control. When the system detects an abnormality, even if the software control system fails, the hardware-level normally closed interface still provides a final safety barrier to ensure the safety of users and equipment.

[0047] like Figure 1 As shown, in an optional embodiment, the gun body 100 is provided with a first baffle 601 and a second baffle 602. The first baffle 601 is arranged at intervals below the operating end 301, and the second baffle 602 is arranged at intervals below the second control component 400.

[0048] The first baffle 601 is positioned at a predetermined location below the operating end 301. When manually operated by the user, the movement range of the operating end 301 is strictly limited within a safe range, preventing damage to the mechanism or misoperation due to excessive force. The second baffle 602 is located below the second control component 400, providing precise stroke limitation for the drive end 401 in automatic control mode. This ensures that the drive end 401 does not exceed the preset range during pushing, avoiding impact damage to the internal structure of the gun body 100. This improves the reliability and service life of the equipment, making it suitable for long-term stable operation in complex environments.

[0049] like Figure 1 As shown, in an optional embodiment, a first reset part 603 is provided between the first baffle 601 and the operation end 301, and a second reset part 604 is provided in the second control component 400 to drive the drive end 401 to reset.

[0050] The first reset unit 603 and the second reset unit 604 ensure that the dual-purpose charging gun automatically returns to its initial state after each operation, preparing it for the next operation. The first reset unit 603 can employ a high-elasticity spring structure, installed between the first baffle 601 and the operating end 301. When the user releases the operating end 301, the spring's elastic force quickly pushes the operating end 301 back to its original position, simultaneously driving the connecting piece 200 and the hook 201 back to the preset initial angle. The second reset unit 604 is integrated inside the second control component 400 and can employ a pneumatic buffer or electromagnetic reset mechanism. After the controller issues a reset command, it can smoothly retract the driving end 401 to the starting position. This improves the convenience and response speed of operation, and also ensures seamless switching between the two operating modes. Users do not need to worry about the impact of previous operations on subsequent uses, greatly enhancing the user experience and the operational efficiency of the equipment.

[0051] like Figure 1 As shown, in an optional embodiment, the gun body 100 is provided with an end cap 701 made of ferromagnetic material on the side away from the connection area, and the end cap 701 is used to magnetically connect the connection end of the robotic arm.

[0052] The ferromagnetic end cap 701 provides a fast, reliable, and precise docking solution for connecting the dual-purpose charging gun to the robotic arm. Made of a special alloy material with high magnetic permeability, and after surface treatment and magnetization, the end cap 701 maintains a stable magnetic attraction when in contact with the robotic arm's connection end, achieving an instantaneous and secure connection. This magnetic connection method offers significant advantages over traditional mechanical latches. The connection process eliminates the need for complex alignment and locking operations, greatly reducing preparation time. In emergencies, a suitable separation force is applied for rapid disengagement, improving system safety and emergency response capabilities. The magnetic connection also features self-centering, automatically adjusting to the optimal connection position even with slight deviations, ensuring smooth and reliable force transmission between the charging gun and the robotic arm, providing a solid foundation for automatic insertion and removal.

[0053] like Figure 1 As shown, in an optional embodiment, the end cap 701 is provided with at least two positioning holes 702, which are used to engage with the connecting end of the positioning robotic arm. The positioning holes 702 further improve the accuracy and repeatability of the connection between the dual-purpose charging gun and the robotic arm.

[0054] At least two positioning holes 702 on the end cap 701 can be asymmetrically distributed to form a precise fit with the positioning pin at the connecting end of the robotic arm, preventing angular offset during connection and ensuring that the spatial position of the gun body 100 relative to the robotic arm is completely consistent each time it is connected. The inner wall of the positioning hole 702 is hardened, providing reliable wear resistance and able to withstand repeated insertion and removal without significant wear. In practical applications, the robotic arm can precisely control the movement trajectory and insertion angle of the gun head 102, greatly improving the success rate and reliability of automatic insertion and removal. This precise positioning capability is particularly important in fast charging scenarios with high precision requirements.

[0055] like Figure 1 As shown, in an optional embodiment, the gun body 100 is provided with a boss 703 for supporting the drive end 401. The boss 703 provides a reaction force support point for the pushing action of the drive end 401. The boss 703 is precisely set at a specific position inside the gun body 100, and when the drive end 401 extends and pushes, the boss 703 can withstand a large force without deformation or wear.

[0056] Based on the same inventive concept, this application also provides a charging system, which includes the dual-purpose charging gun as described above.

[0057] The charging system includes a charging gun with both manual and automatic operation modes, as well as an intelligent control unit, a robotic arm system, a charging management platform, and a safety monitoring module. The entire charging system works collaboratively through a unified communication protocol and control logic, and can automatically switch operating modes according to different scenario requirements.

[0058] In public places or charging stations, the system can operate fully automatically, with a robotic arm identifying the vehicle's location and completing the charging operation. In homes or private locations, users can choose a manual operation mode and enjoy the convenience of traditional charging. This solves the functional limitations of a single device and provides a feasible technical path for the intelligent upgrading of electric vehicle charging infrastructure.

[0059] Specifically, in this charging system, apart from the dual-purpose charging gun and related components which adopt the technical solutions in the above embodiments, the structure, connection relationship, installation position, etc. of other devices can refer to the relevant disclosures of the prior art, and will not be elaborated here.

[0060] It should be understood that the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Although the terms "first," "second," etc., may be used herein to describe various units, these units should not be limited by these terms. These terms are only used to distinguish one unit from another. For example, a first unit may be referred to as a second unit, and similarly, a second unit may be referred to as a first unit, without departing from the scope of the exemplary embodiments of the invention.

[0061] It should be understood that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously. The term " / and" in this article describes another relationship between related objects, indicating that two relationships can exist.
