[0002] Currently, in order to meet the demand for automated logistics in industrial manufacturing factories, the usage and frequency of AGV (Automated Guided Vehicle) carts are constantly increasing. This has also led to a continuous increase in the failure frequency of AGV carts and the damage rate of the electrical components configured on AGV carts.

[0003] However, the layout of existing AGVs is mostly a compact planar layout, which is not conducive to the installation and maintenance of the electrical components of the AGVs, thus affecting the maintenance efficiency of the AGVs. Summary of the Invention

[0017] Furthermore, the sliding member is provided with a guide groove extending along the extension direction of the sliding member, and a guide protrusion is provided on one side of the main body member, the guide protrusion being located within the guide groove and engaging with the guide groove; and / or,

[0018] Both the sliding component and the main body are U-shaped structures.

[0019] Furthermore, the transport vehicle also includes:

[0020] A support structure is provided on the side of the first mounting plate near the second mounting plate. The support structure is movably provided so that when the first mounting plate is in the unfolded position, it moves to a support state in which the support structure is set at a preset angle with the first mounting plate, or when the first mounting plate is in the retracted position, it moves to a retracted state in which the support structure is attached to the first mounting plate.

[0021] Furthermore, the fixing part includes a movable member and a limiting member connected to each other. The movable member is movably disposed so that, when the sliding member moves along the extending direction of the main body, at least a portion of the limiting member forms a limiting space adapted to the power line; or,

[0022] An adsorption part is provided on the power cord, and the fixing part is an adsorption component. The adsorption component is used to adsorb with the adsorption part so that when the sliding part moves along the extension direction of the main body, the adsorption component and the adsorption part adsorb and fix each other.

[0023] Furthermore, the transport vehicle also includes:

[0024] The first resistance detection element is set on the slider and is used to detect the moving resistance of the slider;

[0025] The controller, the first resistance detection element, and one of the first mounting plate and the second mounting plate are all connected to the controller. The controller is used to keep one of the first mounting plate and the second mounting plate stationary when the first resistance detection element detects that the rate of change of the sliding resistance of the slider is greater than a first preset value.

[0026] Furthermore, the transport vehicle also includes:

[0027] The second resistance detection element is disposed on one of the first drive end and the second drive end and is used to detect the movement resistance of one of the first drive end and the second drive end.

[0031] The second weight detection element is installed on the second mounting plate and is used to detect the total weight of the second mounting plate and the electrical components installed on the second mounting plate. Both the second weight detection element and the first drive element are connected to the controller. The controller is used to put the first drive element into a rest state when the second weight detection element detects that the total weight of the second mounting plate and the electrical components installed on the second mounting plate is greater than a preset weight.

[0032] The technical solution of this invention firstly improves the installation and maintenance efficiency of electrical components. Through the synchronous movement design of the first and second mounting plates, they can be quickly unfolded or retracted, enabling rapid installation and maintenance of electrical components without disassembling the transport trolley's outer shell. This significantly saves time and labor costs, improving equipment maintenance efficiency and availability. Secondly, it optimizes the management and protection of power cables. The sliding structure design includes a sliding component and a main body, both with internal cable grooves. This effectively manages and protects the power cables. During the unfolding or retraction of the mounting plates, the sliding component moves in tandem, extending or retracting the power cables within the cable grooves. This prevents the power cables from being stretched, squeezed, or worn during the unfolding or retraction process, ensuring the stability and safety of the electrical connection. Furthermore, the unfolding or retraction of the first and second mounting plates increases the available installation positions for electrical components while reducing the space occupied by the transport trolley, facilitating component layout and improving the space utilization efficiency of the transport trolley. Therefore, the technical solution of this invention solves the technical problem of low maintenance efficiency of AGV trolleys in the prior art. Attached Figure Description

[0060] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] like Figures 1 to 7 As shown, Embodiment 1 of the present invention provides a transport trolley, which includes a first mounting plate 1, a second mounting plate 2, and a sliding structure 3. Both the first mounting plate 1 and the second mounting plate 2 are used to mount electrical components; the first mounting plate 1 is located above the second mounting plate 2, and the first mounting plate 1 and the second mounting plate 2 are synchronously and movably arranged to move to an unfolded position where the first mounting plate 1 and the second mounting plate 2 are misaligned with each other, or to a retracted position where the first mounting plate 1 and the second mounting plate 2 are opposite each other. A sliding structure 3 is disposed on one side of the first mounting plate 1. The sliding structure 3 includes a slider 31 and a main body 32. Both the main body 32 and the slider 31 extend along the extension direction of the first mounting plate 1. The main body 32 and the slider 31 are respectively provided with a first wire groove and a second wire groove for accommodating power cords. The slider 31 is provided with a fixing part for fixing the power cord. The slider 31 is movably disposed on the main body 32 along the extension direction of the main body 32, so as to move to an open position in which at least a portion of the slider 31 extends out to one side of the main body 32, or to a folded position in which at least a portion of the slider 31 is opposite to the main body 32. One of the first mounting plate 1 and the second mounting plate 2 is connected to the slider 31, so that when one of the first mounting plate 1 and the second mounting plate 2 moves to the unfolded position, the slider 31 is in the open position; when one of the first mounting plate 1 and the second mounting plate 2 moves to the retracted position, the slider 31 is in the folded position.

[0062] The transport trolley provided in Embodiment 1 of the present invention firstly improves the efficiency of electrical component installation and maintenance. Through the synchronous movement design of the first mounting plate 1 and the second mounting plate 2, it can be quickly unfolded or retracted, enabling rapid installation and maintenance of electrical components without disassembling the transport trolley's outer shell. This significantly saves time and labor costs, improving equipment maintenance efficiency and availability. Secondly, it optimizes power cable management and protection. The sliding structure 3 is designed with a sliding member 31 and a main body 32, both internally equipped with cable grooves. This effectively manages and protects the power cables. During the unfolding or retraction of the mounting plates, the sliding member 31 moves in tandem, extending or retracting the power cables within the cable grooves. This prevents the power cables from being stretched, squeezed, or worn during the unfolding or retraction process, ensuring the stability and safety of the electrical connection. Furthermore, the unfolding or retraction of the first mounting plate 1 and the second mounting plate 2 increases the available installation positions for electrical components while reducing the space occupied by the transport trolley, facilitating the layout of electrical components and improving the space utilization efficiency of the transport trolley. Therefore, the transport vehicle provided in this embodiment can solve the technical problem of low maintenance efficiency of AGV vehicles in the prior art.

[0063] Specifically, the transport vehicle is an AGV (Automated Guided Vehicle). The power cord is used for connection to a power source.

[0064] Specifically, when the slider 31 is in the folded position, at least a portion of the slider 31 is embedded in the first groove. The first groove and the second groove are interconnected. This design ensures that the power cord can be safely and orderly stored in the first and second grooves when in the folded position, avoiding cable clutter and potential electrical short circuit risks. Simultaneously, the interconnection of the first and second grooves ensures that the power cord can smoothly unfold during the movement of the slider 31 from the folded position to the open position, preventing cable twisting and damage during movement, improving the lifespan of the power cord and the reliability of the electrical system.

[0065] Specifically, along the direction from the first mounting plate 1 to the second mounting plate 2, the distance between the first mounting plate 1 and the second mounting plate 2 is greater than the maximum height of the electrical component. This design ensures that the movement of the mounting plates during installation or maintenance is not interfered with by the electrical component or the internal structure of the transport trolley, providing sufficient operating space. Simultaneously, the sufficient gap between the first mounting plate 1 and the second mounting plate 2 facilitates heat dissipation of the electrical component, reducing the risk of damage due to overheating, thereby improving the stability of the electrical system and extending the service life of the electrical components.

[0066] Specifically, the transport trolley also includes a drive assembly 4, which comprises a first drive member 41 and a second drive member 42 that are mutually driven. The second drive member 42 has a first drive end 421 and a second drive end 422, which are synchronously and movably arranged in opposite directions. The first drive end 421 is driven to the first mounting plate 1, and the second drive end 422 is driven to the second mounting plate 2. With this structural arrangement, the movement of the first mounting plate 1 and the second mounting plate 2 can be precisely and synchronously controlled through the drive assembly 4, enabling rapid unfolding and folding of the mounting plates, providing efficient support for the installation and maintenance of electrical components. Simultaneously, the mutual driving design of the first drive member 41 and the second drive member 42 ensures the stability and synchronicity of the first mounting plate 1 and the second mounting plate 2 during movement, avoiding jamming or damage to the mounting plates caused by uneven driving, and improving the stability and durability of the system. Furthermore, this drive design simplifies the control logic of the transport trolley, making overall operation more convenient and improving the degree of automation and the intelligence level of the system.

[0067] Specifically, the first driving component 41 is a driving roller, and the second driving component 42 is a driving chain, with the driving chain wound around at least a portion of the driving roller. This structural arrangement, using the combination of the driving roller and the driving chain, enables precise and stable power transmission, ensuring accurate and synchronized movement of the first mounting plate 1 and the second mounting plate 2. The rotation of the roller drives the chain, and the linear motion of the chain is converted into translation of the mounting plates. This transmission method offers high flexibility, simple maintenance, and the ability to withstand large loads, improving the reliability and efficiency of the electrical component mounting mechanism. Simultaneously, the fact that at least a portion of the driving roller is wound around the driving chain ensures close contact between the chain and the roller, reducing energy loss during power transmission and improving power transmission efficiency. Specifically, the driving roller is equipped with gears, which are rotatably configured to drive the driving chain.

[0068] Specifically, the first drive end 421 is located above the second drive end 422, and the vertical distance between the first drive end 421 and the second drive end 422 is adjustable. This structural arrangement allows for the adjustment of the vertical distance between the first drive end 421 and the second drive end 422 to accommodate electrical components of different heights, ensuring the stability and safety of the electrical components during installation or maintenance. This adjustable design improves the system's adaptability and flexibility, enabling the same electrical component mounting mechanism to meet the installation requirements of electrical components of different sizes, reducing modifications to the internal structure of the transport trolley, and lowering customization costs.

[0069] Specifically, there are at least two first driving members 41, which are spaced apart along the extension direction of the first mounting plate 1. The spacing between one of the at least two first driving members 41 and the other in the extension direction of the first mounting plate 1 is adjustable. This structural arrangement, using at least two first driving members 41, not only distributes the load, reduces wear on individual first driving members 41, and extends the service life of the first driving members 41 and the second driving member 42, but also improves the smoothness and synchronization of the movement of the first mounting plate 1 and the second mounting plate 2, ensuring the safety of electrical components during movement. Furthermore, by providing first driving members 41 with adjustable spacing in the extension direction of the first mounting plate 1, the position of the first driving members 41 can be adjusted according to the layout of electrical components on the mounting plate to accommodate the installation requirements of different electrical components, improving the flexibility and efficiency of electrical component installation on the transport trolley.

[0070] In this embodiment, the transport trolley also includes a mounting structure 5, which is disposed on one side of the first mounting plate 1. The mounting structure 5 includes a first side plate 51 and a second side plate 52 that are connected to each other and perpendicular to each other. The first side plate 51 is parallel to the first mounting plate 1, and a sliding structure 3 is disposed on the first side plate 51. A second driving member 42 is disposed opposite to the second side plate 52, and the first driving member 41 is connected to the second side plate 52. This structural arrangement and the design of the mounting structure 5 not only provide a stable mounting platform for the sliding structure 3, but also enhance the structural stability and rigidity of the overall mechanism through the perpendicular connection of the first side plate 51 and the second side plate 52, avoiding the impact of vibrations during transportation on electrical components. Simultaneously, the connection between the first driving member 41 and the second side plate 52 enhances the stability of the structure, making the unfolding and retraction of the first mounting plate 1 and the second mounting plate 2 smoother, reducing potential damage to electrical components, and ensuring the stability and safety of the transport trolley in various working environments.

[0071] Specifically, the mounting structure 5 includes mounting members 53, of which there are at least two. One of the mounting members 53 is located on one side of the first mounting plate 1, and the other is located on the other side of the first mounting plate 1. The mounting members 53 extend along the extension direction of the first mounting plate 1. The first driving member 41 is interconnected with the mounting members 53, and the mounting members 53 are mounted on the second side plate 52. The design of using at least two mounting members 53 can distribute the load more evenly, improving the load-bearing capacity and stability of the entire structure. The extension of the mounting members 53 along the extension direction of the first mounting plate 1 ensures stability and reliability during the driving process. At the same time, this design makes the driving of the first mounting plate 1 more uniform, avoiding plate deformation or driving member damage caused by uneven local stress, and extending the service life of the electrical component mounting mechanism.

[0072] Specifically, the mounting component 53 is made of aluminum profile. In this way, using aluminum profile as the mounting component 53 not only provides good strength and rigidity, enabling it to withstand various forces during the operation and maintenance of the transport trolley, but also the lightweight nature of aluminum profile helps to reduce the overall weight of the transport trolley, thereby improving its operating efficiency and flexibility.

[0073] Specifically, the first mounting plate 1 includes a first main board component 11 and a first connecting plate component 12 connected to each other. The first connecting plate component 12 is located on one side of the first main board component 11, and is provided with a first connecting portion 121 for fixed connection with the first driving end 421. There are at least two first connecting plates 12, spaced apart along the extending direction of the first mounting plate 1. This structural arrangement increases the connection strength and structural stability of the first mounting plate 1. In particular, by providing multiple first connecting plates 12, the force connected to the first driving end 421 can be distributed more evenly, avoiding deformation or damage caused by excessive local stress. Simultaneously, the spaced first connecting plates 12 provide a more flexible connection method with the driving assembly 4, facilitating adjustments according to actual needs and improving the adaptability and maintainability of the mounting plate.

[0074] Specifically, the second mounting plate 2 includes a second main board component and a second connecting plate component connected to each other. The second connecting plate component is located on one side of the second main board component and has a second connecting portion for fixed connection with the second drive end 422. There are at least two second connecting plates, spaced apart along the extending direction of the second mounting plate 2. This structural arrangement improves the stability and strength of the connection. The spaced arrangement of the second connecting plates also ensures a uniform distribution of force, avoiding structural problems caused by localized stress, while enhancing the adaptability and adjustability of the second mounting plate 2, facilitating connection with the second drive end 422, and ensuring smoothness and reliability during the driving process.

[0075] Specifically, the second driving member 42 is provided with a third connecting portion 401, located on the side of the second driving member 42 near the first mounting plate 1. The third connecting portion 401 includes at least two third connecting plates, which are spaced apart along the extending direction of the first mounting plate 1. The first connecting plate 12 is used to connect with the third connecting plates by bolts. The second connecting plate is also used to connect with the third connecting plates by bolts. Thus, by providing the third connecting portion 401 on the second driving member 42, including at least two third connecting plates spaced apart along the extending direction of the first mounting plate 1, this design ensures the stability and uniformity of the connection with the first connecting plate 12 and the second connecting plate. Using bolted connections makes the entire connection structure both stable and easy to disassemble and maintain, improving the maintainability and flexibility of the system. Simultaneously, this connection method can accommodate electrical components of different sizes, allowing the first mounting plate 1 and the second mounting plate 2 to be more flexibly unfolded and retracted during the installation and maintenance of electrical components, ensuring efficiency and safety during the installation process.

[0076] In this embodiment, the slider 31 is provided with a guide groove 311 extending along the extension direction of the slider 31, and a guide protrusion 321 is provided on one side of the main body 32. The guide protrusion 321 is located within the guide groove 311 and guides and cooperates with the guide groove 311. This structural arrangement ensures the stability and guidance of the slider 31 during the sliding process, avoids lateral deviation and wobbling of the slider 31 during movement, and improves the stability and reliability of the sliding structure 3. The guiding cooperation between the guide groove 311 and the guide protrusion 321 enables the slider 31 to move accurately between the open and folded positions, ensuring the smooth unfolding and orderly folding of the power cord during the movement of the slider 31, avoiding damage to the power cord, and extending its service life.

[0077] Specifically, both the slider 31 and the main body 32 are U-shaped structures. This effectively increases the depth of the cable tray, providing a safer space for the power cord. Simultaneously, the U-shaped design increases the contact area between the slider 31 and the main body 32, improving stability during sliding. Furthermore, the U-shaped structure provides better rigidity, reducing deformation under load and ensuring the structural stability and durability of the slider 31 and the main body 32 during long-term use, making it suitable for environments with frequent movement and high loads.

[0078] Specifically, the transport trolley also includes a support structure, which is located on the side of the first mounting plate 1 near the second mounting plate 2. The support structure is movably configured to either be in a supported state where the support structure is positioned at a preset angle to the first mounting plate 1 when the first mounting plate 1 is in the extended position, or in a retracted state where the support structure is in contact with the first mounting plate 1 when the first mounting plate 1 is in the retracted position. This movable support structure design provides additional support for the first mounting plate 1 when it is in the extended position, ensuring its stability during the installation or maintenance of electrical components and preventing swaying or tilting due to gravity or external forces, thus improving safety and efficiency during the installation and maintenance of electrical components. When the first mounting plate 1 is in the retracted position, the support structure automatically retracts and contacts the first mounting plate 1, reducing space occupation, preventing interference with the external environment, and improving the flexibility and adaptability of the transport trolley. Furthermore, the automatic adjustment mechanism of the support structure simplifies the operation process and improves automation and user experience.

[0079] Specifically, the fixing part includes a movable member and a limiting member connected to each other. The movable member is movably arranged so that when the sliding member 31 moves along the extending direction of the main body 32, at least a portion of the limiting member forms a limiting space adapted to the power cord. With this structure, the limiting space of the power cord can be dynamically adjusted according to the movement of the sliding member 31, ensuring that a portion of the power cord can be limited within the limiting space during the movement of the sliding member 31, thereby facilitating the unfolding of the power cord that is gathered together in the wire groove during the movement of the sliding member 31.

[0080] It should be noted that "at least part of the limiting component forms a limiting space that is compatible with the power cord" means that the inner diameter of the limiting space is the same as the outer diameter of the power cord.

[0081] In Embodiment 2, the power cord is equipped with an adsorption part, and the fixing part is an adsorption member. The adsorption member is used to adsorb with the adsorption part so that when the sliding member 31 moves along the extension direction of the main body 32, the adsorption member and the adsorption part adsorb and fix each other. In this way, the power cord can be automatically adsorbed and fixed in a set position when the sliding member 31 moves, ensuring that a part of the power cord can be adsorbed inside the sliding member 31 during the movement of the sliding member 31, thereby facilitating the unfolding of the power cord that is gathered together in the wire groove during the movement of the sliding member 31. At the same time, the adsorption fixing method of the adsorption member and the adsorption part avoids the damage to the power cord that may be caused by traditional fixing methods (such as binding or buckling), ensuring the integrity and stability of the power cord, thereby improving the overall performance and safety of the electrical system.

[0082] In Embodiment 1, the transport trolley also includes a first resistance detection element and a controller. The first resistance detection element is disposed on the sliding member 31 and is used to detect the moving resistance of the sliding member 31. The first resistance detection element and one of the first mounting plate 1 and the second mounting plate 2 are connected to the controller. The controller is used to keep one of the first mounting plate 1 and the second mounting plate 2 stationary when the first resistance detection element detects that the rate of change of the moving resistance of the sliding member 31 is greater than a first preset value. With this structural arrangement, the moving resistance of the sliding member 31 can be monitored in real time, and when the resistance increases abnormally, the first mounting plate 1 and the second mounting plate 2 can be automatically controlled to stop moving, preventing damage to the sliding member 31 caused by external resistance or internal faults, avoiding the possibility of the power cord being stuck and torn, and ensuring the safety of electrical components and the stability of the electrical system. Through automated monitoring and control, the intelligence level of the system is improved, operational errors and maintenance costs are reduced, and the adaptability and safety of the transport trolley in complex environments are enhanced.

[0083] In Embodiment 1, the transport trolley further includes a second resistance detection element and a controller. The second resistance detection element is disposed on one of the first drive end 421 and the second drive end 422 and is used to detect the movement resistance of one of the first drive end 421 and the second drive end 422. The second resistance detection element and one of the first drive end 421 and the second drive end 422 are both connected to the controller. The controller is used to stop one of the first drive end 421 and the second drive end 422 when the rate of change of the movement resistance of one of the first drive end 421 and the second drive end 422 detected by the second resistance detection element is greater than a second preset value. In this way, by introducing the second resistance detection element, the change of resistance encountered by the first drive end 421 or the second drive end 422 during movement can be detected. Once the rate of change of resistance exceeds the preset value, the controller will automatically stop the movement of the drive end. This mechanism can prevent overload of the drive end when it encounters obstacles, avoid damage to the drive system and related mechanical components (such as chains, rollers, etc.), improve the reliability and safety of the electrical component mounting mechanism, and also reduce the risk of damage to electrical components caused by overload.

[0084] In Embodiment 1, the transport trolley also includes a controller and a first weight detection component. The first weight detection component is mounted on the first mounting plate 1 and is used to detect the total weight of the first mounting plate 1 and the electrical components mounted on it. Both the first weight detection component and the first drive component 41 are connected to the controller. The controller stops the first drive component 41 when the first weight detection component detects that the total weight of the first mounting plate 1 and the electrical components mounted on it exceeds a preset weight. This structural arrangement allows for real-time detection of the total weight of the electrical components on the mounting plate. Once the weight exceeds a preset safety limit, the controller automatically stops the operation of the first drive component 41, preventing drive system failures and electrical component damage caused by overload, ensuring the safe operation of the electrical component mounting mechanism and the stability of the electrical system. This combination of weight detection and automatic control improves the system's intelligence and safety while reducing maintenance costs.

[0085] Specifically, the transport trolley also includes a second weight detection component, which is mounted on the second mounting plate 2 and used to detect the total weight of the second mounting plate 2 and the electrical components mounted on it. Both the second weight detection component and the first drive component 41 are connected to a controller. The controller stops the first drive component 41 when the second weight detection component detects that the total weight of the second mounting plate 2 and the electrical components mounted on it exceeds a preset weight. This structural arrangement allows for real-time detection of the total weight of the electrical components on the mounting plate. Once the weight exceeds a preset safety limit, the controller automatically stops the operation of the first drive component 41, preventing drive system failures and electrical component damage caused by overload, ensuring the safe operation of the electrical component mounting mechanism and the stability of the electrical system. This combination of weight detection and automatic control improves the system's intelligence and safety while reducing maintenance costs.

[0086] It should be noted that "the total weight of the first mounting plate 1 and the electrical components mounted on the first mounting plate 1" refers to the sum of the weight of the first mounting plate 1 and the weight of the electrical components mounted on the first mounting plate 1. "The total weight of the second mounting plate 2 and the electrical components mounted on the second mounting plate 2" refers to the sum of the weight of the second mounting plate 2 and the weight of the electrical components mounted on the second mounting plate 2.

[0087] It should be noted that when the first driving component 41 is in a resting state, the driving end of the first driving component 41 stops moving.

[0088] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: reduce the difficulty of installation and maintenance of electrical components inside the AGV vehicle; and expand the layout space of electrical components inside the AGV vehicle.

[0089] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0090] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0091] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0092] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0093] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0094] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
