Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to an adjustment device and an intelligent blackboard. Background Technology

[0002] Traditional smart blackboards typically connect the main and secondary screens via a quick-release latch, which usually relies on rotating a screw for adjustment. However, the screw needs to be adjusted before connection, which is inconvenient, and because the screw pitch is fixed, there is an unavoidable gap during adjustment.

[0003] If the adjustment is not correct and a gap is formed, foam filling is required. After long-term use, the foam will age, warp, break, or shrink, resulting in visible gaps or foreign objects such as chalk dust that are difficult to remove. If the adjustment is too tight and an interference fit is formed, the secondary screen will be forced to rotate backward, causing a gap to appear between the main and secondary screens, thus affecting the user experience and structural stability. Utility Model Content

[0004] Therefore, it is necessary to provide an adjustment device and a smart blackboard to address the above problems. The adjustment device can flexibly adjust the distance between the two structures.

[0005] This utility model first provides an adjustment device for connecting a first structure and a second structure, comprising: a first connector for being disposed in one of the first structure and the second structure; a base for being disposed in the other of the first structure and the second structure; and a connecting assembly disposed in the base and having a separated state and a connected state. The connecting assembly includes a fixing member and a second connector, the second connector being disposed in the fixing member and capable of reciprocating relative to the fixing member in a preset direction. In the separated state, the second connector is separated from the first connector; in the connected state, the second connector is connected to the first connector and is capable of driving the first connector to slide closer to / away from the base, so that the first structure and the second structure move closer to / away from each other.

[0006] In the above-mentioned adjustment device, after the second connector is connected to the first connector, the distance between the second connector and the first connector can be adjusted by controlling the second connector to slide relative to the fixed member in a preset direction. This allows for flexible adjustment of the distance between the first structure and the second structure, improving the overall stability of the structure and enhancing the user experience. Furthermore, the second connector can be adjusted while connected, making the adjustment process simple, easy for users to operate, and improving adjustment efficiency.

[0007] In one embodiment, the adjusting device further includes an adjusting component disposed on the connecting component, the adjusting component being capable of driving the second connecting member.

[0008] With this configuration, users can actively and precisely control the sliding of the second connector relative to the fixed component by adjusting the components, thereby enabling more accurate and convenient adjustment of the gap between the first and second structures.

[0009] In one embodiment, the adjustment assembly includes a knob and a first transmission member. The knob is disposed on the fixing member and is rotatable about a first preset axis relative to the fixing member. The two sides of the first transmission member are respectively connected to the knob and the second connecting member to convert the rotation of the knob about the first preset axis into the sliding of the second connecting member along the preset direction.

[0010] This configuration makes the adjustment method simple and smooth, allowing for a more compact structural arrangement of the adjustment components on the connecting components. The adjustment components can achieve stepless adjustment, thereby enabling flexible and precise control of the distance between the first and second connecting parts, and thus achieving high-precision adjustment of the distance between the first and second structures.

[0011] In one embodiment, the adjustment assembly further includes a first connecting shaft extending along a second preset axis. The knob is connected to the first transmission member via the first connecting shaft. The second connecting member is provided with a transmission groove. The first transmission member is disposed in the transmission groove and is capable of swinging around a third preset axis. The second preset axis and the third preset axis are arranged opposite to each other on both sides of the first preset axis.

[0012] With this configuration, the knob of the adjustment component and the first transmission component adopt an eccentric structure to achieve transmission, which is simple in structure and easy to process and assemble.

[0013] In one embodiment, the adjustment assembly further includes a handle, which is disposed on the knob and has an unlocked state and a locked state; in the unlocked state, the handle and the knob can drive the first transmission member to move; in the locked state, the first transmission member does not move with the handle and the knob.

[0014] This design effectively prevents accidental movement of the second connector, thereby achieving the self-locking and anti-accidental-touch functions of the adjustment device and improving the stability and reliability of the long-term connection between the first and second structures.

[0015] In one embodiment, the adjustment assembly further includes a second transmission member and an elastic member. The second transmission member is disposed on the side of the knob facing the first transmission member. The second transmission member can rotate around the first preset axis together with the knob and can slide relative to the knob along the first preset axis. The two ends of the elastic member abut against the second transmission member and the first transmission member, respectively. In the unlocked state, the handle pushes the second transmission member toward the first transmission member, and the elastic member is compressed. And / or, the handle can rotate relative to the knob around a fourth preset axis to switch between the unlocked state and the locked state. The fourth preset axis is perpendicular to the first preset axis. In the unlocked state, the handle is perpendicular to the fixing member. In the locked state, the handle is parallel to the fixing member.

[0016] This design simplifies the unlocking and locking mechanism, making it easy to manufacture and assemble, as well as user-friendly. In the unlocked state, the handle stands upright for easy operation, while in the locked state, it lies flat, saving space, creating a cleaner appearance, and further reducing the risk of accidental contact with the handle.

[0017] In one embodiment, the first connector includes a connecting portion, and the second connector has a connecting hole. The connecting hole has an insertion hole and a fixing hole that are interconnected along the preset direction. The connecting portion can be inserted into the insertion hole and slid to the fixing hole to restrict the separation of the first connector and the second connector.

[0018] With this design, the connecting part cooperates with the fixed hole to achieve multi-directional limiting, effectively preventing the first and second connecting parts from accidentally disengaging due to vibration or external force.

[0019] In one embodiment, the first connector further includes a mounting portion for being disposed in one of the first structure and the second structure, and the connecting portion is disposed in the mounting portion and is T-shaped; or, the connecting portion is a screw.

[0020] This design allows the mounting section to be easily fixedly connected to the second blackboard. The connection section has a simple and reliable structure, making it easy to process and assemble. Using screws as the first connecting part provides high versatility and reduces the number of parts in the adjustment device, thus lowering costs.

[0021] In one embodiment, the adjusting device further includes a support spring, and the connecting assembly is rotatably connected to the base via the support spring to switch between the separated state and the connected state.

[0022] With this configuration, the support spring can provide a stable holding force for the connecting components in both the separated and connected states, preventing the connecting components from wobbling and thus improving the stability and reliability of the connection between the first and second connecting components.

[0023] This utility model also provides an intelligent blackboard, including a first blackboard, a second blackboard and the adjustment device as described above, wherein the first connecting member is disposed on one of the first blackboard and the second blackboard, and the base is disposed on the other of the first blackboard and the second blackboard.

[0024] This setup allows for flexible adjustment of the distance between the first and second blackboards via an adjustment device, enhancing the user experience of the smart blackboard. Attached Figure Description

Detailed Implementation

[0034] 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.

[0035] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application's specification are for illustrative purposes only and do not represent the only possible implementation.

[0036] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0039] Traditional smart blackboards typically connect the main and secondary screens via a quick-release mechanism, which relies on a screw for adjustment. However, due to the fixed screw pitch, gaps are unavoidable during adjustment. If the adjustment is incomplete, resulting in a gap fit, foam filling is necessary. Over time, this foam can age, warp, break, or shrink, leading to visible gaps or the accumulation of chalk dust and other foreign matter. Conversely, if the adjustment is too tight, creating an interference fit, the secondary screen will rotate backward under pressure, causing a gap to appear between the main and secondary screens, affecting both user experience and structural stability.

[0040] To solve the above problems, such as Figures 1 to 7 As shown, this utility model provides an adjustment device that can flexibly adjust the distance between two structures.

[0041] like Figures 1 to 2 As shown, specifically, the adjusting device is used to connect the first structure and the second structure, including a first connector 1, a base 2, and a connecting assembly 3. The first connector 1 is used to be disposed in one of the first structure and the second structure; the base 2 is used to be disposed in the other of the first structure and the second structure; the connecting assembly 3 is disposed in the base 2 and has a separated state and a connected state. The connecting assembly 3 includes a fixing member 31 and a second connector 32. The second connector 32 is disposed in the fixing member 31 and can slide back and forth relative to the fixing member 31 in a preset direction. In the separated state, the second connector 32 is separated from the first connector 1; in the connected state, the second connector 32 is connected to the first connector 1 and can drive the first connector 1 to slide closer to or away from the base 2, so that the first structure and the second structure move closer to or further away from each other.

[0042] For ease of description, the following description uses the first structure shown in the figure as the first blackboard 6 and the second blackboard 7, with the first connector 1 located on the first blackboard 6 and the base 2 located on the second blackboard 7 as an example. Of course, in other embodiments, the first connector 1 may be located on the second blackboard 7 and the base 2 may be located on the first blackboard 6. Alternatively, the first structure and the second structure may be two displays, two splicing boards, or other structures that need to be interconnected. This embodiment of the present invention does not impose specific limitations here.

[0043] In the adjustment device provided in this embodiment of the utility model, after the second connecting member 32 is connected to the first connecting member 1, the distance between the second connecting member 32 and the first connecting member 1 can be adjusted by controlling the second connecting member 32 to slide relative to the fixing member 31 in a preset direction. This allows for flexible adjustment of the distance between the first blackboard 6 and the second blackboard 7, ensuring a tight and uniform fit between them. This avoids problems such as gaps or foreign objects in the gaps caused by clearance fits, and also avoids problems such as the first blackboard 6 or the second blackboard 7 rotating backward or opening due to interference fits. This improves the stability of the overall structure and enhances the user experience. Furthermore, the second connecting member 32 can be adjusted while connected, making the adjustment process simple, easy for users to operate, and improving adjustment efficiency.

[0044] In the illustrated embodiment, the preset direction is perpendicular to the sidewalls where the first blackboard 6 and the second blackboard 7 are attached, i.e., the X-axis direction shown in the figure. Of course, in other embodiments, the preset direction may also form an angle with the direction perpendicular to the sidewalls where the first blackboard 6 and the second blackboard 7 are attached.

[0045] like Figures 1 to 3 As shown, in one embodiment, the adjustment device further includes an adjustment component 4 disposed on the connecting component 3, which can drive the second connecting member 32. Thus, the user can actively and precisely control the sliding of the second connecting member 32 relative to the fixing member 31 through the adjustment component 4, thereby more accurately and conveniently adjusting the distance between the first blackboard 6 and the second blackboard 7, without the need for external tools, making operation simple and convenient. Of course, in other embodiments, the second connecting member 32 can also be slid relative to the fixing member 31 in a preset direction using external tools or by direct manual pushing.

[0046] like Figures 3 to 4As shown, in one embodiment, the adjustment component 4 includes a knob 41 and a first transmission member 42. The knob 41 is mounted on the fixed member 31 and can rotate about a first preset axis a relative to the fixed member 31. The two sides of the first transmission member 42 are respectively connected to the knob 41 and the second connecting member 32, so as to convert the rotation of the knob 41 about the first preset axis a into the sliding of the second connecting member 32 along a preset direction. When the user rotates the knob 41, its rotational motion is converted into the linear sliding of the second connecting member 32 along the preset direction through the first transmission member 42. This adjustment method is simple and smooth, making the structural arrangement of the adjustment component 4 on the connecting component 3 more compact. At the same time, the adjustment component 4 can achieve stepless adjustment, thereby flexibly and accurately controlling the distance between the first connecting member 1 and the second connecting member 32, and thus achieving high-precision adjustment of the distance between the first blackboard 6 and the second blackboard 7.

[0047] like Figure 3 As shown in the illustrated embodiment, the adjustment assembly 4 further includes a first connecting shaft 43 extending along a second preset axis b. The knob 41 and the first transmission member 42 are connected via the first connecting shaft 43. The second connecting member 32 is provided with a transmission groove 321. The first transmission member 42 is disposed within the transmission groove 321 and can swing around a third preset axis c. The second preset axis b and the third preset axis c are arranged opposite each other on both sides of the first preset axis a. When the knob 41 rotates around the first preset axis a, it drives the first connecting shaft 43 to rotate synchronously around the first preset axis a. The position where the first transmission member 42 is connected to the first connecting shaft 43 moves synchronously with the first connecting shaft 43. Due to the transmission cooperation between the first transmission member 42 and the transmission groove 321, the first transmission member 42 swings around the third preset axis c within the transmission groove 321, simultaneously pushing the second connecting member 32 to slide along a preset direction. Thus, the knob 41 and the first transmission member 42 of the adjustment assembly 4 adopt an eccentric structure to achieve transmission, resulting in a simple structure that is easy to process and assemble. Specifically, the transmission groove 321 includes a limiting groove 3211 and a swing groove 3212 that are interconnected. The first transmission member 42 includes a limiting part 421 and a swing part 422 that are interconnected. The limiting part 421 is disposed in the limiting groove 3211, and the third preset axis c is located at the center of the limiting part 421 and the limiting groove 3211. The swing part 422 is disposed in the swing groove 3212, and the swing part 422 is provided with a first hole 423 that is rotatably connected to the first connecting shaft 43.

[0048] Of course, in other embodiments, the adjusting component 4 may also adopt other structures such as cam mechanism, linkage mechanism, gear and rack mechanism, which can convert rotational motion into linear sliding of the second connecting member 32, or directly drive the second connecting member 32 to slide in a straight line. This utility model embodiment does not impose specific limitations here.

[0049] like Figure 4As shown, the adjustment assembly 4 also includes a handle 44, which is located on the knob 41 and has an unlocked state and a locked state. In the unlocked state, the handle 44 and the knob 41 can drive the first transmission member 42 to move; in the locked state, the first transmission member 42 does not move with the handle 44 and the knob 41. When adjustment is required, the handle 44 is moved to the unlocked state, and the user can control the handle 44 to drive the knob 41 to rotate around the first preset axis a, and drive the second connecting member 32 to slide in a preset direction through the first transmission member 42; after adjustment, the handle 44 is moved to the locked state, at which time the second connecting member 32 cannot be controlled to move through the handle 44 and the knob 41. In this way, the accidental movement of the second connecting member 32 due to accidental collision, equipment vibration or misoperation is effectively prevented, thereby realizing the self-locking and anti-accidental touch function of the adjustment device, and improving the stability and reliability of the long-term connection between the first blackboard 6 and the second blackboard 7.

[0050] like Figure 4 As shown, in one embodiment, the handle 44 is rotatable relative to the knob 41 about a fourth preset axis d to switch between an unlocked state and a locked state. The fourth preset axis d is perpendicular to the first preset axis a. In the unlocked state, the handle 44 is perpendicular to the fixing member 31; in the locked state, the handle 44 is parallel to the fixing member 31. Thus, in the unlocked state, the handle 44 is upright for easy user operation; in the locked state, the handle 44 is flat, saving space and making the appearance neater, while further reducing the risk of accidental contact with the handle 44. Of course, in other embodiments, the handle 44 can also use other methods such as pressing, tooth engagement, or magnetic attraction to switch between the unlocked and locked states.

[0051] like Figures 3 to 4As shown, in one embodiment, the adjustment assembly 4 further includes a second transmission member 45 and an elastic member 46. The second transmission member 45 is located on the side of the knob 41 facing the first transmission member 42. The second transmission member 45 can rotate around a first preset axis a together with the knob 41 and can slide relative to the knob 41 along the first preset axis a. The two ends of the elastic member 46 abut against the second transmission member 45 and the first transmission member 42, respectively. In the unlocked state, the handle 44 pushes the second transmission member 45 toward the first transmission member 42, and the elastic member 46 is compressed. In the unlocked state, the elastic element 46 presses against the first transmission element 42, resulting in a relatively large force exerted on the first transmission element 42 by the handle 44, knob 41, second transmission element 45, and elastic element 46 as a whole, thus enabling the first transmission element 42 to move synchronously. In the locked state, the first transmission element 42 can slide back to the side away from the first transmission element 42 under the action of the elastic force of the elastic element 46, resulting in a relatively small force exerted on the first transmission element 42 by the handle 44, knob 41, second transmission element 45, and elastic element 46 as a whole, which cannot drive the first transmission element 42 to move synchronously. Thus, the structure of the adjustment component 4 for unlocking and locking is simple, easy to manufacture and assemble, and also easy for users to operate. The elastic element 46 can be a spring or other elastic element; this embodiment of the invention does not impose specific limitations.

[0052] Furthermore, such as Figures 3 to 4 As shown, the handle 44 includes a locking part 441 extending along the fourth preset axis d. When the handle 44 is upright, the dimension of the locking part 441 along the first preset axis a is greater than the dimension of the locking part 441 along the first preset axis a when the handle 44 is flat, so that when the handle 44 is upright, the locking part 441 can push the second transmission member 45 toward the first transmission member 42.

[0053] like Figure 3 As shown, the adjustment assembly 4 also includes a second connecting shaft 47. The two ends of the second connecting shaft 47 are connected to the second transmission member 45 and the knob 41, respectively. The first connecting shaft 43 and the second connecting shaft 47 are located on opposite sides of the first preset axis a, ensuring that the second transmission member 45 can rotate around the first preset axis a together with the knob 41. The second transmission member 45 is also provided with two second holes 451 corresponding to the first connecting shaft 43 and the second connecting shaft 47, respectively. The first connecting shaft 43 and the second connecting shaft 47 pass through the corresponding second holes 451 and can move up and down within the second holes 451, allowing the second transmission member 45 to slide relative to the knob 41 along the first preset axis a.

[0054] like Figure 3As shown, the fixing member 31 has a rotating hole 311 centered on the first preset axis a. The second transmission member 45 is rotatably disposed within the rotating hole 311 to limit the movement of the second transmission member 45, ensuring that the knob 41 and the second transmission member 45 always rotate around the first preset axis a, and that the second transmission member 45 always slides along the first preset axis a, thereby improving the stability and reliability of the adjustment assembly 4 during the adjustment process. Simultaneously, the fixing member 31 may also have a guide groove (not shown) extending along a preset direction. The second connecting member 32 is slidably disposed within the guide groove, ensuring that the second connecting member 32 always slides along the preset direction, thereby improving the stability and reliability of the second connecting member 32 during the adjustment process.

[0055] like Figures 4 to 5 As shown, in one embodiment, the first connector 1 includes a connecting portion 11, and the second connector 32 is provided with a connecting hole 322. The connecting hole 322 has an insertion hole 3221 and a fixing hole 3222 that are interconnected along a preset direction. The connecting portion 11 can be inserted into the insertion hole 3221 and slide to the fixing hole 3222 to restrict the separation of the first connector 1 and the second connector 32. During installation, the connecting portion 11 is first aligned and inserted into the insertion hole 3221, and then the connecting portion 11 is controlled to slide to the fixing hole 3222. Then, the second connector 32 is controlled by the adjusting component 4 to drive the first connector 1 to slide along the preset direction. After the adjustment is completed, the control handle 44 moves to the locked state. The connecting part 11 engages with the fixing hole 3222, preventing the connecting part 11 from disengaging from the direct connecting hole 322. It also restricts the movement of the first connecting member 1 relative to the second connecting member 32 in a direction perpendicular to a preset direction, achieving multi-directional limiting and effectively preventing the first connecting member 1 and the second connecting member 32 from accidentally disengaging due to vibration or external force, thereby improving the stability and reliability of the connection between the first connecting member 1 and the second connecting member 32. Preferably, the fixing hole 3222 is located on the side of the insertion hole 3221 away from the base 2, so that when the second connecting member 32 slides towards the side closer to the base 2, the connecting part 11 can automatically slide from the insertion hole 3221 to the fixing hole 3222.

[0056] like Figures 5 to 6As shown, specifically, in one embodiment, the first connector 1 further includes a mounting portion 12, which is used to be disposed in one of the first structure and the second structure. The connecting portion 11 is disposed on the mounting portion 12 and is T-shaped. Specifically, the T-shaped connecting portion 11 includes a connecting section 111 and a limiting section 112. The two ends of the connecting section 111 are respectively connected to the center of the limiting section 112 and the mounting portion 12. The cross-sectional dimension of the limiting section 112 is larger than the cross-sectional dimension of the fixing hole 3222 and smaller than the cross-sectional dimension of the insertion hole 3221; the cross-sectional dimension of the connecting section 111 is equal to or slightly smaller than the cross-sectional dimension of the fixing hole 3222. When the connecting portion 11 is engaged with the fixing hole 3222, the limiting section 112 can abut against the side of the second connector 32 away from the mounting portion 12, and the side wall of the connecting section 111 can abut against the inner wall of the fixing hole 3222 to achieve multi-directional limiting. The mounting part 12 can be easily fixedly connected to the second blackboard 7, and the connecting part 11 has a simple and reliable structure, making it easy to process and assemble. The first connecting part 1 can be a sheet metal part, and the connecting part 11 can be bent into shape.

[0057] like Figure 7 As shown, in another embodiment, the connecting part 11 is a screw. Specifically, the screw includes a small-diameter section (not shown) and a large-diameter section 113. The small-diameter section has threads and is used for fixed connection with the second black plate 7. The cross-sectional dimension of the large-diameter section 113 is larger than the cross-sectional dimension of the fixing hole 3222 and smaller than the cross-sectional dimension of the insertion hole 3221; the cross-sectional dimension of the small-diameter section is equal to or slightly smaller than the cross-sectional dimension of the fixing hole 3222. When the connecting part 11 mates with the fixing hole 3222, the large-diameter section 113 can abut against the side of the second connecting member 32 away from the mounting part 12, and the peripheral wall of the small-diameter section can abut against the inner wall of the fixing hole 3222 to achieve multi-directional limiting. Using a screw as the first connecting member 1 has high versatility and can reduce the number of parts in the adjustment device, thus reducing costs.

[0058] Of course, in other embodiments, the first connector 1 and the second connector 32 can also switch between the connected state and the disconnected state by means of snaps, screws or other methods.

[0059] like Figure 3As shown, in one embodiment, the adjusting device further includes a support spring 5. The connecting component 3 is rotatably connected to the base 2 via the support spring 5 to switch between a separated state and a connected state. The connecting component 3 has a simple structure, making it easy for the user to control its switching between the separated and connected states. The support spring 5 provides a stable holding force for the connecting component 3 in both the separated and connected states, preventing the connecting component 3 from wobbling arbitrarily, thereby improving the stability and reliability of the connection between the first connecting member 1 and the second connecting member 32. Of course, in other embodiments, the connecting component 3 can also be directly rotatably connected to the base 2 via a shaft, pin, or other structure, or the connecting component 3 can also slide relative to the base 2 to switch between the separated and connected states.

[0060] like Figures 1 to 2 As shown, this embodiment of the present invention also provides a smart blackboard, including a first blackboard 6, a second blackboard 7, and the aforementioned adjustment device. A first connecting member 1 is disposed on one of the first blackboard 6 and the second blackboard 7, and a base 2 is disposed on the other. Thus, the distance between the first blackboard 6 and the second blackboard 7 can be flexibly adjusted via the adjustment device, ensuring a tight and uniform fit between them. This avoids problems such as gaps or foreign objects in the gaps caused by clearance fits, and also avoids problems such as the first blackboard 6 or the second blackboard 7 rotating backward or opening due to interference fits. This improves the overall structural stability and enhances the user experience of the smart blackboard. Of course, this adjustment device can also be used in other devices that require adjusting the distance between two structures, such as displays and splicing boards; this embodiment of the present invention does not impose specific limitations on these applications.

[0061] 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.

[0062] 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 scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
