Description

Technical Field

[0001] This application relates to the field of display screen installation technology, and in particular to a display screen splicing structure and display screen module. Background Technology

[0002] As an important display device for outdoor advertising and media, LED all-in-one displays (or LED poster machines) are facing increasingly higher display requirements, with pixel pitch gradually shifting from large to small. Due to diverse usage scenarios, the assembled screens need to support wall mounting or ceiling mounting.

[0003] Most existing LED all-in-one displays use die-cast cabinet structures for splicing. However, using die-cast cabinets results in a double-sized bezel inside the screen, leading to a bulky structure, large space occupation, numerous splicing components, and low assembly efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a display splicing structure and display module to address the issue that the entire screen has a double outer bezel size after splicing using die-cast cabinets.

[0005] This application provides a display screen splicing structure, the display screen splicing structure comprising:

[0006] A first profile and a second profile arranged along a first direction, the sides of the first profile and the second profile forming a mounting surface for mounting a display screen;

[0007] A locking element and a sliding block, the locking element passing through the first profile and the sliding block being slidably connected to the second profile;

[0008] The sliding block has an unlocked position and a locked position. The locked position is higher than the unlocked position. When it is in the unlocked position, the sliding block is located inside the second profile. When it is in the locked position, the sliding block partially extends out of the second profile and is connected to the locking member.

[0009] In one embodiment, the display splicing structure further includes a front connecting plate connected to the first profile and the second profile to tighten and align the first profile and the second profile.

[0010] In one embodiment, the display splicing structure further includes a first embedded part and a second embedded part. The first embedded part is provided on the first profile, and the second embedded part is provided on the second profile. Both the first embedded part and the second embedded part are connected to the front connecting plate.

[0011] In one embodiment, the second profile has a receiving cavity for accommodating the sliding block, and the second profile is provided with a groove communicating with the receiving cavity. One end of the second embedded part is located outside the second profile, and the other end passes through the groove and the sliding block and abuts against the cavity wall of the receiving cavity. The extending direction of the groove is parallel to the first direction.

[0012] In one embodiment, a plurality of first embedded parts are provided, and the plurality of first embedded parts are arranged at intervals along the length direction of the first profile; and / or, a plurality of second embedded parts are provided, and the plurality of second embedded parts are arranged at intervals along the length direction of the second profile.

[0013] In one embodiment, the display splicing structure further includes a limiting member that can pass through the second profile and be threadedly connected to the sliding block to restrict the sliding block from sliding within the second profile; or...

[0014] The limiting member can pass through the second profile and abut against the sliding block to restrict the sliding block from sliding within the second profile.

[0015] In one embodiment, a limiting track is provided on the outer wall of the second profile, and the limiting member passes through the limiting track and extends into the second profile.

[0016] In one embodiment, the sliding block is U-shaped, with its closed end located inside the second profile and its open end able to slide out of the second profile. The end of the locking member passes through the open end and is threadedly connected to the sliding block.

[0017] In one embodiment, the sliding block includes:

[0018] A sliding part is provided through the second profile, and the sliding part has a first connecting hole;

[0019] The first abutting part has a second connecting hole communicating with the first connecting hole. The first abutting part is disposed at one end of the sliding part and is located between the first profile and the second profile. The first abutting part can abut against the bottom end surface of the first profile.

[0020] The end of the locking member passes through the second connecting hole and is threaded to the wall of the first connecting hole.

[0021] In one embodiment, the sliding block further includes a second abutting portion, which is disposed at one end of the sliding portion away from the abutting portion, and the second abutting portion is located outside the second profile.

[0022] In one embodiment, the second profile has a receiving cavity for accommodating the sliding block, the cavity wall of which is adapted to the outer peripheral surface of the sliding block to restrict relative rotation between the sliding block and the second profile.

[0023] This application also provides a display module, including a display screen and the display splicing structure described in any of the above claims.

[0024] The aforementioned display splicing structure, through the arrangement of first and second profiles along a first direction, allows the sides of the first and second profiles to jointly form the display mounting surface. The structural strength of the profiles themselves is sufficient to support and install the display, eliminating the need for space-consuming bezels. Through the cooperation of locking components and sliding blocks, when the sliding block is in the unlocked position, it is located within the second profile, avoiding interference with wall-mounted installation. When splicing fixation or hoisting requirements are needed, the sliding block slides to the locked position, at which point the sliding block extends beyond the second profile and connects with the locking components. This connection method using locking components and sliding blocks replaces the traditional locking splicing structure, reducing the number of components required for splicing, simplifying the assembly process, and improving assembly efficiency. Simultaneously, it eliminates the need for a heavy die-cast housing, reducing overall structural costs, and can also adapt to the load-bearing requirements of hoisting scenarios.

[0025] In traditional die-cast cabinet assembly, each cabinet has its own independent outer frame. After assembly, the frames of adjacent cabinets overlap, inevitably forming a double-sized outer frame. This results in a significant loss of internal space and makes the screen bulky. However, the first and second profiles in this application are not independent "cabinet" structures. They are arranged along a first direction with their sides serving as mounting surfaces. No separate outer frame is needed; the structural strength of the profiles themselves is sufficient to support and position the display screen. This eliminates the possibility of overlapping frames forming a double-sized frame, reducing the space occupied and improving space utilization. Attached Figure Description

[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] As an important display device for outdoor advertising and media, LED all-in-one displays (or LED poster machines) are facing increasingly higher display requirements, with pixel pitch gradually shifting from large to small. Due to diverse usage scenarios, the assembled screens need to support wall mounting or ceiling mounting.

[0053] Most existing LED all-in-one displays use die-cast cabinet structures for splicing. However, using die-cast cabinets results in a double-sized bezel inside the screen, leading to a bulky structure, large space occupation, numerous splicing components, and low assembly efficiency.

[0054] In this embodiment, the first and second profiles are arranged along a first direction, and the first and second profiles are unlocked or locked using locking members and sliding blocks. After the first and second profiles are locked, the display screen can be directly installed on the sides of the first and second profiles without the need for a separate complete outer bezel. The structural strength of the profiles themselves is sufficient to support and position the display screen, thus eliminating the need for a double bezel, reducing the space occupied by the screen and improving space utilization.

[0055] This application provides a display screen splicing structure, such as Figures 1 to 10As shown, the display splicing structure includes: a locking member 300, a sliding block 400, and a first profile 100 and a second profile 200 arranged along a first direction. The sides of the first profile 100 and the second profile 200 form a mounting surface for mounting the display screen. The locking member 300 passes through the first profile 100, and the sliding block 400 is slidably connected to the second profile 200. The sliding block 400 has an unlocked position and a locked position. The locked position is higher than the unlocked position. When in the unlocked position, the sliding block 400 is located inside the second profile 200. When in the locked position, the sliding block 400 partially extends out of the second profile 200 and is connected to the locking member 300.

[0056] The aforementioned display splicing structure, through the arrangement of the first profile 100 and the second profile 200 along the first direction, allows the sides of the first profile 100 and the second profile 200 to jointly form the display mounting surface. The structural strength of the profiles themselves is sufficient to support and install the display, eliminating the need for space-consuming bezels. Through the cooperation of the locking component 300 and the sliding block 400, when the sliding block 400 is in the unlocked position, it is located within the second profile 200, avoiding interference with wall-mounted installation. When splicing fixation or hoisting requirements are needed, the sliding block 400 slides to the locked position, at which point a portion of the sliding block 400 extends beyond the second profile 200 and connects with the locking component 300. This connection between the locking component 300 and the sliding block 400 replaces the traditional locking splicing structure, reducing the number of components required for splicing, simplifying the assembly process, and improving assembly efficiency. Simultaneously, it eliminates the need for a heavy die-cast housing, reducing overall structural costs, and can also adapt to the load-bearing requirements of hoisting scenarios.

[0057] In traditional die-cast cabinet assembly, each cabinet has its own independent outer frame. After assembly, the frames of adjacent cabinets overlap, inevitably forming a double-sized outer frame. This results in a significant loss of internal space and makes the screen bulky. However, the first profile 100 and the second profile 200 of this application are not independent "cabinet-type" structures. The first profile 100 and the second profile 200 are arranged along the first direction with their sides serving as mounting surfaces. There is no need for separate outer frames. The structural strength of the profiles themselves is sufficient to support and position the display screen. This eliminates the possibility of overlapping frames forming a double-sized frame, reduces the occupation of internal space, and improves space utilization.

[0058] It should be noted that, as Figures 1 to 10 As shown, the first profile 100 and the second profile 200 are tubular structures.

[0059] In one embodiment, such as Figures 1 to 10As shown, the display splicing structure also includes a front connecting plate 500, which is connected to the first profile 100 and the second profile 200 to tighten and align the first profile 100 and the second profile 200. Through the connection between the front connecting plate 500 and the first profile 100 and the second profile 200, the front connecting plate 500 can exert a tension force on the first profile 100 and the second profile 200 arranged along the first direction, reducing the relative displacement that may occur between the first profile 100 and the second profile 200 during installation or use due to external forces, their own weight, and other factors. Simultaneously, the front connecting plate 500 can align and calibrate the splicing parts of the first profile 100 and the second profile 200, preventing unevenness on the mounting surface of the display screen due to misalignment of the profiles, thereby ensuring the flatness of the mounting surface during subsequent display screen installation.

[0060] In one embodiment, such as Figures 1 to 10 As shown, the display splicing structure also includes a first embedded part 110 and a second embedded part 210. The first profile 100 is provided with the first embedded part 110, and the second profile 200 is provided with the second embedded part 210. Both the first embedded part 110 and the second embedded part 210 are connected to the front connecting plate 500. The first embedded part 110 is set as the connection medium between the first profile 100 and the front connecting plate 500, and the second embedded part 210 is set as the connection medium between the second profile 200 and the front connecting plate 500.

[0061] Compared to the direct connection of the front connecting plate 500 to the first profile 100 and the second profile 200, the first embedded part 110 and the second embedded part 210 can form an integrated structure with the corresponding profile in advance, avoiding the problem of loose connection caused by the material characteristics of the profile or insufficient structural strength of the connection position when directly connected; at the same time, the first embedded part 110 and the second embedded part 210 can play a positioning role for the connection position of the front connecting plate 500, ensuring that the front connecting plate 500 can accurately correspond to the preset connection point of the first profile 100 and the second profile 200.

[0062] In one embodiment, such as Figures 1 to 10 As shown, multiple first embedded parts 110 are provided, and the multiple first embedded parts 110 are arranged at intervals along the length direction of the first profile 100. The multiple spaced first embedded parts 110 form multi-point force support along the length direction of the first profile 100, so that the connection force between the front connecting plate 500 and the first profile 100 is evenly distributed to different positions of the first profile 100, avoiding local deformation of the first profile 100 due to force concentration at a single connection point.

[0063] In one embodiment, such as Figures 1 to 10As shown, multiple second embedded parts 210 are provided, and these multiple second embedded parts 210 are arranged at intervals along the length direction of the second profile 200. The multiple spaced-apart second embedded parts 210 create uniform connection stress points along the length direction of the second profile 200, so that the tension force and positioning effect of the front connecting plate 500 on the second profile 200 cover the second profile 200, preventing the second profile 200 from bending or shifting due to uneven stress.

[0064] In this embodiment, as Figures 1 to 10 As shown, there are two of each of the first embedded part 110 and the second embedded part 210. In other embodiments, the number of the first embedded part 110 and the second embedded part 210 is determined according to the actual operation requirements, for example, three, four or even more.

[0065] In one embodiment, such as Figures 1 to 10 As shown, the front connecting plate 500 is connected to the first profile 100 by the first fastener 700 and to the second profile 200 by the second fastener 800.

[0066] In one embodiment, such as Figures 1 to 6 As shown, the first profile 100 and / or the second profile 200 are provided with reinforcing ribs 900 to enhance the structural strength of the first profile 100 and / or the second profile 200.

[0067] This application provides two embodiments. Figures 1 to 5 Example 1 Figures 6 to 10 This is Example 2. The main difference between Example 1 and Example 2 is the structure that restricts the relative rotation of the sliding block 400 and the second profile 200, the structure of the limiting member 600, and the structure of the sliding block 400.

[0068] In Example 1, as Figures 1 to 5 As shown, the second profile 200 has a receiving cavity for accommodating the sliding block 400. The second profile 200 is provided with a groove 220 communicating with the receiving cavity. One end of the second embedded part 210 is located outside the second profile 200, and the other end passes through the groove 220 and the sliding block 400, abutting against the cavity wall. The extending direction of the groove 220 is parallel to the first direction. The receiving cavity of the second profile 200 provides sliding space for the sliding block 400, ensuring that the sliding block 400 can move along a preset trajectory and guaranteeing that the sliding block 400 switches between the unlocked and locked positions. The second embedded part 210 passes through the groove 220 and the sliding block 400 and abuts against the cavity wall, so that the second embedded part 210 can be connected to the front connecting plate 500 and restrict the relative rotation of the sliding block 400 and the second profile 200 without the need for additional components to restrict the rotation of the sliding block 400. At the same time, the second embedded part 210 passes through the groove 220, thereby restricting the movement trajectory of the sliding block 400 to form a limit, ensuring that the sliding block 400 moves along the first direction.

[0069] In Example 1, as Figures 1 to 5 As shown, the display splicing structure also includes a limiting member 600. The limiting member 600 can pass through the second profile 200 and be threadedly connected to the sliding block 400 to restrict the sliding block 400 from sliding within the second profile 200. When the limiting member 600 is threadedly connected to the sliding block 400, the second profile 200 and the sliding block 400 are directly locked, preventing the sliding block 400 from accidentally sliding due to vibration, external interference, or its own weight when not in operation, ensuring that the sliding block 400 always remains in the preset position.

[0070] It is understandable that when it is necessary to connect the locking member 300 and the sliding block 400, the limiting member 600 must be rotated first to unlock the second profile 200 and the sliding block 400, so that the sliding block 400 can move within the second profile 200.

[0071] In Example 1, as Figures 1 to 5 As shown, the sliding block 400 is U-shaped. The closed end of the sliding block 400 is located inside the second profile 200, and the open end of the sliding block 400 can slide out of the second profile 200. The end of the locking member 300 passes through the open end and is threadedly connected to the sliding block 400. By setting the sliding block 400 to a U-shape, with the closed end located inside the second profile 200, the contact area between the sliding block 400 and the receiving cavity of the second profile 200 is increased, providing a supporting foundation for the sliding block 400. The open end can extend out of the second profile 200, facilitating a threaded connection with the locking member 300. By connecting the open end to the locking member 300, there is no need to perform complex drilling on the second profile 200, simplifying the structural processing flow.

[0072] It is understandable that the locking element 300 and the sliding block 400 are threaded together, and the sliding block 400 can switch between the unlocked position and the locked position through the threaded engagement between the two.

[0073] In Example 1, as Figures 1 to 5 As shown, the open end of the sliding block 400 is provided with a chamfer 440. By providing a chamfer 440 at the open end, not only is it possible to prevent sharp edges from scratching operators or scraping other parts during the sliding process of the sliding block 400 sliding out of the second profile 200, but also, when the end of the locking member 300 passes through the open end and is threadedly connected to the sliding block 400, the chamfer 440 can play a guiding role, guiding the locking member 300 to quickly and accurately align with the connection position of the open end.

[0074] In Example 2, as Figures 6 to 10As shown, the second profile 200 has a receiving cavity for accommodating the sliding block 400. The cavity wall is adapted to the outer peripheral surface of the sliding block 400 to restrict relative rotation between the sliding block 400 and the second profile 200. By adapting the cavity wall of the receiving cavity to the outer peripheral surface of the sliding block 400, when the sliding block 400 rotates about the first direction, the sliding block 400 can abut against the cavity wall of the receiving cavity, thereby restricting relative rotation between the sliding block 400 and the second profile 200.

[0075] It should be noted that the cavity wall of the receiving cavity and the outer peripheral surface of the sliding block 400 are adapted to each other, that is, the cross-sectional shape of the receiving cavity is complementary to the cross-sectional shape of the sliding block 400, so that the sliding block 400 cannot rotate inside the receiving cavity.

[0076] In one specific embodiment, the cross-sectional shape of the receiving cavity and the cross-section of the sliding block 400 are both non-circular.

[0077] In one specific embodiment, the cross-sectional shape of the receiving cavity is the same as that of the sliding block 400, which is polygonal or elliptical.

[0078] In Example 2, as Figures 6 to 10 As shown, the display splicing structure also includes a limiting member 600. The limiting member 600 can pass through the second profile 200 and abut against the sliding block 400 to restrict the sliding of the sliding block 400 within the second profile 200. By setting the limiting member 600 so that it passes through the second profile 200 and abuts against the sliding block 400, the displacement of the sliding block 400 can be restricted by physical obstruction. The structure is simple and easy to operate, and it is convenient to quickly release the limiting member to adjust the position of the sliding block 400 according to installation requirements.

[0079] In Example 2, as Figures 6 to 10 As shown, a limiting track 610 is provided on the outer wall of the second profile 200, and the limiting member 600 passes through the limiting track 610 and extends into the second profile 200. By providing the limiting track 610 on the outer wall of the second profile 200, the limiting track 610 can limit the insertion depth of the limiting member 600, preventing damage to the sliding block 400 or the internal structure of the second profile 200 due to excessive insertion, and also avoiding insufficient limiting effect due to shallow insertion. Moreover, the limiting track 610 is located on the outer wall of the second profile 200, making it easy for operators to visually observe the position of the limiting member 600, and to quickly locate and operate the limiting member 600 when the position of the sliding block 400 needs to be adjusted.

[0080] In Example 2, as Figures 6 to 10As shown, the sliding block 400 includes a sliding part 410 and a first abutting part 420. The sliding part 410 passes through the second profile 200 and has a first connecting hole 411. The first abutting part 420 has a second connecting hole 421 communicating with the first connecting hole 411. The first abutting part 420 is located at one end of the sliding part 410 and between the first profile 100 and the second profile 200. The first abutting part 420 can abut against the bottom end face of the first profile 100. The end of the locking member 300 passes through the second connecting hole 421 and is threaded to the wall of the first connecting hole 411.

[0081] The sliding part 410 passes through the second profile 200, providing a sliding guide for the sliding block 400 and ensuring that the sliding block 400 moves in a preset direction within the second profile 200. The locking member 300 passes through the second connecting hole 421 and is threadedly connected to the first connecting hole 411, achieving precise docking between the sliding block 400 and the locking member 300. The first abutting part 420 is located between the first profile 100 and the second profile 200 and can abut against the bottom surface of the first profile 100. When the sliding block 400 is in the locked position, physical support can be formed through the direct abutment between the first abutting part 420 and the first profile 100. Combined with the threaded connection of the locking member 300, the connection stability between the first profile 100 and the second profile 200 is enhanced.

[0082] Compared to other connection methods, the locking element 300 and the sliding block 400 are connected by threads, which not only makes disassembly and assembly convenient, but also allows the connection tightness to be adjusted by the degree of tightening, adapting to the structural strength requirements of different installation scenarios.

[0083] In Example 2, as Figures 6 to 10 As shown, the sliding block 400 also includes a second abutment portion 430, which is located at the end of the sliding portion 410 opposite to the abutment portion and outside the second profile 200. By positioning the second abutment portion 430 outside the second profile 200, when the sliding portion 410 slides along the second profile 200, the second abutment portion 430 limits the sliding stroke of the sliding portion 410, preventing the sliding portion 410 from sliding completely into the second profile 200 due to excessive sliding and becoming difficult to remove, or from coming out of the second profile 200 and causing structural failure.

[0084] In other words, such as Figure 4 and Figure 5 The sliding block 400 provided in Embodiment 1 of this application is shown, and as shown in the figure... Figure 9 and Figure 10 The sliding blocks provided in Embodiment 2 shown are all threadedly connected to the sliding block 400 via the locking member 300, thereby driving the sliding block 400 to switch between the locked position and the unlocked position.

[0085] It should be noted that, in this first embodiment, as Figure 2 and Figure 4 As shown, when the sliding block 400 is in the unlocked position, the sliding block 400 is located at the bottom of the second profile 200; as Figure 3 and Figure 5 As shown, when the sliding block 400 is in the locked position, the sliding block 400 rises to the top of the second profile 200 and abuts against the bottom end face of the first profile 100. In this second embodiment, as... Figure 7 and Figure 9 As shown, when the sliding block 400 is in the unlocked position, the first abutment portion 420 of the sliding block 400 overlaps with the second profile 200; as Figure 8 and Figure 10 As shown, when the sliding block 400 is in the locked position, the first abutting part 420 of the sliding block 400 rises and abuts against the bottom end face of the first profile 100.

[0086] By setting the sliding block 400, when locked, the sliding block 400 is threadedly connected to the locking member 300, and part of the sliding block 400 extends out of the second profile 200 and abuts against the first profile 100, forming an additional force point, which enhances the connection strength between the first profile 100 and the second profile 200, improves the load-bearing capacity of the overall structure, and is especially suitable for scenarios with high load-bearing requirements such as hoisting.

[0087] During installation, when the sliding block 400 is in the unlocked position, the sliding block 400 of the first embodiment is completely inside the second profile 200 and does not protrude outside the second profile 200. Therefore, it will not interfere with the installation of surrounding structures and is suitable for various installation methods. The sliding block 400 of the second embodiment overlaps the second profile 200 and will not interfere with the installation of surrounding structures.

[0088] Additionally, it should be noted that the sliding block 400 is a pre-installed structure, already installed within the second profile 200 at the factory, while the front connecting plate 500 can be installed on-site according to actual splicing needs, facilitating transportation and on-site assembly, and improving installation efficiency and flexibility.

[0089] This application also provides a display module, including a display screen and a display splicing structure as described above. Integrating the display splicing structure with the display screen allows the display screen to be directly attached to the mounting surface formed by the profile, eliminating the need for additional heavy cabinets, thus reducing the overall weight and volume of the display module and improving space utilization.

[0090] 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.

[0091] The above embodiments merely illustrate 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.
