Description

Technical Field

[0001] This application relates to the field of engine assembly technology, and in particular to support devices, engine assembly tooling, and process operation methods. Background Technology

[0002] An engine assembly line is a production line process for sequentially assembling engines. Each station operates on a production line basis, so the control of each link must have high reliability and a certain degree of sensitivity to ensure the continuity and stability of production.

[0003] Engine assembly lines typically use roller conveyors to transport parts between workstations. Operators stand on the side of the roller conveyor to assemble the components. However, the installation heights of different engine components vary, and a single workstation generally installs components at the same height. Since there are many engine components, engine assembly lines require a large number of workstations, resulting in high transport time and labor costs, and low assembly efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a support device, engine assembly tooling, and process operation method to address the problem of low assembly efficiency on engine assembly lines.

[0005] An embodiment of the first aspect of this application provides a support device, the support device comprising:

[0006] A support plate having a first surface for supporting an external object, the support plate having a folded state and an unfolded state;

[0007] A base, wherein the base and the support plate are arranged side by side along a first direction;

[0008] An unfolding and retracting assembly is disposed between the base and the support plate, such that the support plate is movably connected to the base, and the unfolding and retracting assembly drives the support plate to switch between the retracted state and the unfolded state;

[0009] When the support plate is in the retracted state, the support plate is attached to the base.

[0010] When the support plate is in the unfolded state, the unfolding assembly separates the first surface of the support plate from the base along the first direction, so that a separation gap is formed between the first surface and the base.

[0011] In one embodiment, the deployment and reception components include:

[0012] A connector, the first end of which is rotatably connected to the support plate, and the second end of which is rotatably connected to the base;

[0013] A locking member is provided along the first direction. The first end of the locking member is detachably connected to the support plate, and the second end of the locking member is detachably connected to the base, so as to lock the relative position of the support plate and the base.

[0014] In one embodiment, the locking element is configured as a positioning pin, the first end of which is inserted into the support plate and the second end of which is inserted into the base.

[0015] In one embodiment, the connector includes:

[0016] The rod body; and

[0017] The bent portion has an angle between it and the length direction of the rod body;

[0018] The bent portion has a first connecting end, a second connecting end, and a contact surface. The first connecting end is fixedly connected to the end of the rod body, the second connecting end is rotatably connected to the support plate or the base, and the contact surface is the side of the bent portion away from the rod body.

[0019] When the support plate is in the unfolded state, the contact surface abuts against the support plate or the base that is connected to the second connecting end.

[0020] In one embodiment, the support device further includes a cylinder component, one end of which is rotatably connected to the support plate, and the other end of which is rotatably connected to the base.

[0021] During the process of switching the support plate from the unfolded state to the retracted state, the cylinder component can provide damping force for the relative movement of the support plate and the base.

[0022] An embodiment of the second aspect of this application provides an engine assembly fixture, including a roller conveyor and the aforementioned support device. The roller conveyor is disposed on the ground, and a receiving space is provided between the roller conveyor and the ground. At least a portion of the support device can enter the receiving space along a second direction, which intersects with the first direction.

[0023] In one embodiment, the engine assembly fixture further includes a limiting component, the accommodating space having a retaining inner wall in the second direction, and the limiting component being disposed between the retaining inner wall and the supporting device along the second direction to limit the relative position of the supporting device and the retaining inner wall.

[0024] In one embodiment, the limiting component includes:

[0025] A limiting plate, the limiting plate being used to connect with the inner wall of the baffle;

[0026] A telescopic component, one end of which is connected to the limiting plate and the other end of which is connected to the supporting device;

[0027] The telescopic member can extend and retract along the second direction to adjust the relative position of the support device and the inner wall of the retaining wall.

[0028] In one embodiment, the support device further includes a gripping portion disposed on the support plate, the gripping portion and the limiting component being disposed on opposite sides of the support plate along the second direction.

[0029] An embodiment of the third aspect of this application proposes a process operation method based on the aforementioned engine assembly tooling, the process operation method comprising:

[0030] When high-level operations are required, the support device is moved out of the accommodating space, the unfolding assembly is adjusted to unfold, and the first surface of the support plate is separated from the base by the unfolding assembly;

[0031] When low-level operations are required, adjust the extension and retraction components to retract them so that the support plate fits against the base and the support device is retracted into the receiving space.

[0032] The aforementioned support device, comprising a base, a support plate, and an unfolding assembly, is positioned between the base and the support plate, allowing the support plate to be movably connected to the base. The unfolding assembly switches the support plate between a retracted and an unfolded state. When high-level operation is required, the unfolding assembly adjusts the support plate to the unfolded state, with the first surface of the support plate separating from the base, allowing the support plate to reach a higher height for the operator to stand and perform high-level operations. When low-level operation is required, the unfolding assembly adjusts the support plate to the retracted state, allowing the support plate to fit against the base, and the operator to stand on the first surface. Alternatively, the retracted support device can be folded up for low-level operations. This allows the operator to perform installation operations at different heights on assembly components from the same workstation, accommodating two or more types of parts. The device features a simple structure, convenient height adjustment and storage, and efficient use of process space, reducing the number of workstations, conveying time, and labor costs, thereby effectively improving assembly efficiency.

[0046] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0047] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and 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 of this application.

[0048] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0051] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0052] See Figure 1 , Figure 1 This diagram illustrates the upper structure of the support device in its extended state according to an embodiment of this application. The support device 1 provided in one embodiment includes a base 12, a support plate 11, and an extension / retraction assembly 13. The support plate 11 has a first surface 111 for supporting external objects. Optionally, the support plate 11 can be used for an operator to stand on. The support plate 11 has a retracted state and an extended state to support external objects at different positions. The base 12 and the support plate 11 are arranged side-by-side along a first direction. Optionally, the base 12 and the support plate 11 are parallel, or the base 12 and the support plate 11 may be angled in the first direction, forming an inclined arrangement, as long as the support plate 11 can support external objects. The retractable assembly 13 is disposed between the base 12 and the support plate 11, allowing the support plate 11 to be movably connected to the base 12. The retractable assembly 13 drives the support plate 11 to switch between a retracted state and an extended state. Specifically, when the support plate 11 is in the retracted state, it can be fitted against the base 12, providing support for external objects. When the support plate 11 is in the extended state, the retractable assembly 13 separates the first surface 111 of the support plate 11 from the base 12 along a first direction, creating a separation gap between the first surface 111 and the base 12, thereby allowing the first surface 111 to provide support for external objects in another position.

[0053] With this configuration, the support device 1 in this embodiment can be used for the operator to stand on, and the first direction can be configured as a vertical direction. When a high-level operation is required, the unfolding assembly 13 can adjust the support plate 11 to the unfolded state, and the first surface 111 of the support plate 11 is separated from the base 12, so that the support plate 11 is switched to a higher height, allowing the operator to stand for high-level operation. When a low-level operation is required, the unfolding assembly 13 can adjust the support plate 11 to the retracted state, and the support plate 11 can be attached to the base 12, allowing the operator to stand on the first surface 111, or the retracted support device 1 can be retracted for low-level operation. This allows the operator to perform installation operations at different heights on the assembly parts at the same workstation, and can assemble and adjust two or more parts. The structure is simple, the height is adjustable and easy to store, the process space can be rationally utilized, the number of workstations is reduced, and the conveying time and labor costs are reduced accordingly, thereby effectively improving assembly efficiency and solving the problem of low assembly efficiency in engine assembly lines.

[0054] In this embodiment, the drive method for switching the state of the support plate 11 by the extension and retraction assembly 13 can be manually driven by the operator, or it can be driven by a drive component. That is, the extension and retraction assembly 13 may include a drive component, which is movably connected between the base 12 and the support plate 11. The drive component may be, but is not limited to, a cylinder or a hydraulic cylinder. In addition, several types of high and low position operations are specifically described here. For example, adjusting the intake and exhaust valve clearance in an engine with in-cylinder braking is a high position operation, while assembling a flywheel housing is a low position operation.

[0055] See Figure 1-2 In some embodiments, the unfolding assembly 13 includes a connector 131 and a locking member 132. The first end of the connector 131 is rotatably connected to the support plate 11, and the second end of the connector 131 is rotatably connected to the base 12. When the support plate 11 is switched to the folded state, the connector 131 can gradually approach a state parallel to the base 12. When the support plate 11 is switched to the unfolded state, the connector 131 can gradually approach a state perpendicular to the base 12.

[0056] The locking member 132 is arranged along the first direction. The first end of the locking member 132 is detachably connected to the support plate 11, and the second end of the locking member 132 is detachably connected to the base 12. The connection between the first end of the locking member 132 and the support plate 11 can be, but is not limited to, a plug-in connection, a threaded connection, a snap-fit ​​connection, or a magnetic connection. The connection between the second end of the locking member 132 and the base 12 can be, but is not limited to, a plug-in connection, a threaded connection, a snap-fit ​​connection, or a magnetic connection. When the support plate 11 is in the unfolded state, the first end of the locking member 132 can be connected and fixed to the support plate 11, and the second end of the locking member 132 can be connected and fixed to the base 12, thereby fixing the relative rotational position of the connecting member 131 and the support plate 11, as well as the relative rotational position of the connecting member 131 and the base 12. At this time, the locking member 132 can cooperate with the connecting member 131 to jointly support between the support plate 11 and the base 12, and the support plate 11 can remain in the unfolded state, thereby providing stable support for external objects.

[0057] In this embodiment, multiple connectors 131 may be provided, and the connectors 131 may be arranged in pairs, and the connectors 131 may be located on opposite sides of the base 12. Optionally, four connectors 131 may be provided.

[0058] In some embodiments, the extension and retraction assembly 13 can separate the first surface 111 of the support plate 11 relative to the base 12 to different separation distances, so that the support plate 11 has multiple heights. Specifically, the support plate 11 is provided with one or more first connection positions for detachable connection of the first end of the locking member 132, and the base 12 is provided with multiple second connection positions for detachable connection of the second end of the locking member 132. The first end of the locking member 132 can be connected to the first connection position respectively, and the second end of the locking member 132 can be connected to the second connection position respectively, so that a corresponding separation distance is formed between the first surface 111 and the base 12.

[0059] See Figure 1-2 In some embodiments, the locking member 132 is configured as a positioning pin. The first end of the positioning pin is inserted into the support plate 11, and the second end of the positioning pin is inserted into the base 12. The positioning pin is arranged along a first direction, that is, the support plate 11 and the base 12 may be provided with corresponding insertion holes. When the support plate 11 is in the unfolded state, the positioning pin can be inserted into the support plate 11 and the base 12 respectively. The positioning pin can limit the relative position of the connector 131, the support plate 11, and the base 12, so that the support plate 11 remains in the unfolded state. If it is necessary to switch the support plate 11 to the retracted state, one or both ends of the positioning pin can be removed from the corresponding insertion holes to switch the state of the support plate 11, which is convenient.

[0060] In this embodiment, the locking member 132 can also be configured as a spring pin structure, that is, a spring is added on the basis of the positioning pin. The spring can be set between the positioning pin and the support plate 11, or the spring can be set between the positioning pin and the base 12. It can provide a certain elastic force when the positioning pin is pulled out. After the operator releases the positioning pin, the positioning pin can automatically spring back to its original position under the action of the spring, which is convenient for adjustment and use.

[0061] In some embodiments, the base 12 and the support plate 11 may be, but are not limited to, a frame structure or a shell structure, enabling lightweight design and reducing the overall weight of the support device 1. A connector 131 may be disposed on the side of the base 12 and the side of the support plate 11 to reduce movement interference between the connector 131, the base 12, and the support plate 11. The surface of the base 12 facing the support plate 11 may be provided with a second surface 121. The second surface 121 and the first surface 111 may be frame-type support surfaces or solid surfaces. Anti-slip structures may be provided on the second surface 121 and the first surface 111. These anti-slip structures may be, but are not limited to, multiple protrusions, and the material of the anti-slip structures may be, but is not limited to, rubber or silicone.

[0062] See Figure 2-3 In some embodiments, the connector 131 includes a rod body 1311 and a bent portion 1312. The bent portion 1312 and the rod body 1311 are provided with an angle in the length direction, that is, the extension line of the length of the bent portion 1312 intersects the extension line of the length of the rod body 1311.

[0063] The bent portion 1312 has a first connecting end 13121, a second connecting end 13122, and a contact surface 13123. The first connecting end 13121 is fixedly connected to the end of the rod body 1311, the second connecting end 13122 is used to rotatably connect with the support plate 11 or the base 12, and the contact surface 13123 is the side of the bent portion 1312 away from the rod body 1311.

[0064] The support plate 11 or base 12 may have an abutment surface. When the support plate 11 is in the unfolded state, the contact surface 13123 abuts against the support plate 11 or base 12 corresponding to the second connecting end 13122. At this time, the contact surface 13123 can limit and stop the relative rotation between the rod body 1311 and the corresponding support plate 11 or base 12, reduce the over-rotation between the rod body 1311 and the corresponding support plate 11 or base 12, and increase the supporting area between the rod body 1311 and the corresponding support plate 11 or base 12, thereby improving the support stability of the rod body 1311 on the support plate 11 or base 12.

[0065] In this embodiment, one or two bending portions 1312 may be provided on the same connector 131. When two bending portions 1312 are provided, the two bending portions 1312 may be respectively provided at both ends of the rod body 1311, and the two bending portions 1312 may be respectively provided on both sides of the rod body 1311 to form a Z-shaped structure. Specifically, the two bending portions 1312 may be referred to as the first bending portion 1312 and the second bending portion 1312, respectively. The first bending portion 1312 is connected between the rod body 1311 and the support plate 11, and the second bending portion 1312 is connected between the rod body 1311 and the base 12. When the support plate 11 is in the unfolded state, the contact surface 13123 of the first bent portion 1312 abuts against the abutting surface of the support plate 11, and the contact surface 13123 of the second bent portion 1312 abuts against the abutting surface of the base 12. That is, abutting and limiting are formed between the connector 131 and the support plate 11, and between the connector 131 and the base 12, making the support more stable.

[0066] See Figure 2 and Figure 4 In some embodiments, the support device 1 further includes a cylinder 14, one end of which is rotatably connected to the support plate 11, and the other end of which is rotatably connected to the base 12. During the process of the support plate 11 switching from an unfolded state to a retracted state, the cylinder 14 provides damping force for the relative movement of the support plate 11 and the base 12, i.e., the cylinder 14 can act as a buffer between the support plate 11 and the base 12 to prevent hand pinching.

[0067] In this embodiment, when the support plate 11 is in the unfolded state, the axis of the cylinder component 14 can deviate from the first direction and be inclined along the relative rotation direction of the support plate 11 and the base 12. Specifically, when the support plate 11 switches from the unfolded state to the retracted state, the support plate 11 compresses the cylinder component 14, and the extension distance of the piston rod of the cylinder component 14 decreases. When the support plate 11 switches from the retracted state to the unfolded state, the support plate 11 stretches the cylinder component 14, and the extension distance of the piston rod of the cylinder component 14 increases.

[0068] See Figure 4-5Another embodiment of this application provides an engine assembly fixture, including a roller conveyor 2 and the aforementioned support device 1. The roller conveyor 2 is disposed on the ground, and a receiving space 21 is provided between the roller conveyor 2 and the ground. At least a portion of the support device 1 can enter the receiving space 21 along a second direction, which intersects with the first direction. With this configuration, the engine assembly fixture can be used to assemble engines, and the roller conveyor 2 can serve as a conveyor mechanism for assembly line operations, used to place and transport engine components. An operator can perform installation operations from the side of the roller conveyor 2. When high-level operations are required, the support device 1 can be moved out of the receiving space 21 along the second direction, and the unfolding assembly can adjust the support plate 11 to an unfolded state. The first surface 111 of the support plate 11 is separated from the base 12, so that the support plate 11 is switched to a higher height, allowing the operator to stand and perform high-level operations.

[0069] When low-position operations are required, the extension and retraction assembly 13 can adjust the support plate 11 to a retracted state, and the support plate 11 can be attached to the base 12. The operator can stand on the first surface 111, or the retracted support device 1 can be stored in the receiving space 21 along the second direction, allowing the operator to stand on the ground and perform low-position operations. This allows the operator to perform installation operations at different heights on the assembly parts at the same workstation. The structure is simple, the height is adjustable and easy to store, reducing the number of workstations, and thus reducing the conveying time and labor costs, thereby effectively improving assembly efficiency.

[0070] In this embodiment, the second direction can be along a horizontal direction, and the angle formed by the intersection of the second direction and the first direction can be an acute angle or a right angle. The support device 1 can enter or leave the receiving space 21 under the action of external force. Optionally, the support device 1 can be manually pushed and pulled by the operator, which is flexible. Alternatively, a displacement mechanism can be provided between the support device 1 and the inner wall of the receiving space 21. The displacement mechanism can be, but is not limited to, a cylinder, a hydraulic cylinder, or a screw and nut structure. The displacement mechanism includes a fixed end and a movable end that can move relative to each other. The fixed end can be connected to the inner wall of the receiving space 21, and the movable end can be connected to the support device 1. The relative movement of the fixed end and the movable end can drive the support device 1 to move relative to the receiving space 21, so as to move into or out of the receiving space 21.

[0071] See Figure 4 In some embodiments, the support device 1 further includes a roller 16, which is disposed on the base 12, that is, the roller 16 can be disposed at the bottom of the base 12, so that the support device 1 can be moved to the required position more conveniently according to actual needs, thereby making it easier for the support device 1 to move into or out of the accommodating space 21.

[0072] See Figure 4-5In some embodiments, the engine assembly fixture further includes a limiting component 3. The accommodating space 21 has a retaining inner wall 211 in the second direction. The limiting component 3 is disposed between the retaining inner wall 211 and the supporting device 1 in the second direction to limit the relative position of the supporting device 1 and the retaining inner wall 211. With this configuration, when the supporting device 1 moves into the accommodating space 21, the limiting component 3 can be located between the retaining inner wall 211 and the supporting device 1, which can support the supporting device 1 at different distances from the retaining inner wall 211 in the second direction, reducing the possibility of the supporting component moving too far.

[0073] In some embodiments, the limiting component 3 includes a limiting plate 31 and a telescopic member 32. The limiting plate 31 is used to connect with the inner wall 211 of the retaining structure. The connection can be, but is not limited to, a magnetic connection, a bolt connection, a snap-fit ​​connection, or a plug-in connection. The limiting plate 31 can increase the contact area 13123 with the inner wall 211 of the retaining structure, making the connection and support between the inner wall 211 of the retaining structure and the limiting component 3 more stable. One end of the telescopic member 32 is connected to the limiting plate 31, and the other end is connected to the support device 1. The telescopic member 32 can move telescopically in a second direction to adjust the relative position between the support device 1 and the inner wall 211 of the retaining structure. That is, according to the use needs of the support device 1, the telescopic member 32 can be used to adjust the distance between the limiting plate 31 and the support device 1 to different distances so that the support device 1 can be moved into different preset positions within the accommodating space 21.

[0074] In this embodiment, the telescopic member 32 can be, but is not limited to, located in a telescopic tube, a cylinder, or a hydraulic cylinder, as long as it can form a separation distance between the support device 1 and the inner wall 211 of the retaining device. Specifically, the telescopic member 32 can be a telescopic tube structure, and the telescopic member 32 can include at least two sleeved tubes. After the adjacent tubes are sleeved, they can move relative to each other. The connection between the adjacent tubes can be, but is not limited to, a threaded connection, a snap-fit ​​connection, or a plug-in connection. After moving to a preset position, it can be tightened. The tubes at both ends of the telescopic member 32 are referred to as the first tube and the second tube. The first tube can be connected to the base 12 of the support device 1, and the second tube can be connected to the limiting plate 31.

[0075] See Figure 1 The limiting plate 31 may be provided with a groove 311, which can be used to provide clearance space for the support device 1. That is, the telescopic member 32 is provided on the side or bottom of the support device 1. When the telescopic member 32 is retracted to the shortest position, the edge of the base 12 of the support device 1 can extend into the groove 311 to reduce the positional interference between the support device 1 and the limiting plate 31.

[0076] See Figure 4In some embodiments, the support device 1 further includes a gripping part 15, which is disposed on the support plate 11. The gripping part 15 and the limiting component 3 are disposed on both sides of the support plate 11 along the second direction, so that the operator can manually grip the gripping part 15 and drive the support device 1 to move along the arrangement direction of the limiting component 3, making it more convenient to apply force.

[0077] In this embodiment, the grip portion 15 may be, but is not limited to, a handle or a grippable protrusion or opening groove, as long as it allows the hand to perform gripping operations.

[0078] In some embodiments, the engine assembly fixture further includes a wire groove 4 and an air supply pipe 5. The wire groove 4 may be provided with wiring, which can be used to provide power to the components on the roller conveyor 2 or the components of the support device 1. The air supply pipe 5 can be used to provide air to the components on the roller conveyor 2 or the components of the support device 1. When the support device 1 is retracted into the receiving space 21, the wire groove 4 and the air supply pipe 5 may be located below the support device 1.

[0079] Another embodiment of this application provides a process operation method. Based on the above-described engine assembly tooling, the process operation method includes:

[0080] When high-level operations are required, the support device 1 is moved out of the accommodating space 21, the extension and retraction assembly 13 is adjusted to unfold, and the first surface 111 of the support plate 11 is separated from the base 12 by the extension and retraction assembly 13.

[0081] When low-level operations are required, adjust the extension and retraction assembly 13 to retract it so that the support plate 11 fits against the base 12 and the support device 1 is retracted into the receiving space 21.

[0082] With this configuration, the engine assembly fixture can be used to implement the process operation method of this embodiment. When performing high-level operations, the support device 1 can be moved outward and unfolded to form a higher support state. When performing low-level operations, the support device 1 can be retracted and stored in the accommodating space 21, utilizing the space below the roller conveyor 2 for storage. This reduces the impact on the operator's working space when performing low-level operations, allowing the operator to perform installation operations at different heights on the assembly parts at the same workstation. The structure is simple, height adjustment and storage are convenient, reducing the number of workstations, and consequently reducing conveying time and labor costs, thereby effectively improving assembly efficiency.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
