Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a garbage guiding structure and a cleaning robot. Background Art

[0002] As people's living standards continue to improve, cleaning robots are becoming increasingly popular, freeing people from various cleaning tasks and improving their sense of well-being. The trash bins of some cleaning robots typically include an entrance at a certain height. To ensure that garbage passes through this entrance and is collected in the trash bin, a garbage guide structure is required. Existing garbage guide structures often use fixed inclined plates or belt conveyors. Cleaning robots using this technology cannot achieve both effective garbage collection and good obstacle-crossing capabilities. Utility Model Content

[0003] Based on this, it is necessary to address the defects of the garbage guiding structure in the existing technology and provide a garbage guiding structure and a cleaning robot that take into account both garbage guiding effect and obstacle crossing ability.

[0006] The mounting base is provided on the chassis of the cleaning equipment;

[0007] A guide assembly is mounted on the mounting base via a movable connection assembly, the guide assembly being tilted in the front-to-back direction, with the lower edge of the guide assembly contacting the working surface;

[0008] When the lower edge of the guide assembly is subjected to an impact force, the guide assembly is pushed back and lifted up relative to the mounting base; when the impact force disappears, the guide assembly is reset.

[0009] The technical solution is further described below:

[0010] In one embodiment, the movable connection assembly includes a first connecting rod and a second connecting rod arranged at an interval from each other, one end of the first connecting rod and one end of the second connecting rod are hinged to the mounting base, and the other end of the first connecting rod and the other end of the second connecting rod are hinged to the guide assembly, so that the mounting base, the first connecting rod, the guide assembly and the second connecting rod cooperate to form a connecting rod mechanism.

[0011] In one embodiment, the guide assembly has a center plane parallel to the vertical plane, there are two first connecting rods and two second connecting rods, the two first connecting rods and the two second connecting rods are symmetrically arranged about the center plane and are respectively located on both sides of the mounting base.

[0012] In one embodiment, the mounting base is provided with a first limiting portion, and the first limiting portion is used to cooperate with the guide assembly in a limiting manner when the guide assembly is in an initial position;

[0013] And / or, the mounting base is provided with a second limiting portion, and the second limiting portion is used to cooperate with the guide assembly in a limiting manner when the guide assembly is lifted to a preset position.

[0014] In one embodiment, the garbage guide structure further includes an elastic member, both ends of which are connected to the mounting base and the guide assembly respectively, and is configured to stretch when the lower edge of the guide assembly is subjected to an impact force, and rebound and reset when the impact force disappears.

[0015] In one embodiment, the guide assembly includes a guide shovel and a first front shovel. The guide shovel is rotatably mounted on the mounting base. Along the tilting direction of the guide shovel, the first front shovel is detachably mounted on the lower side of the guide shovel and is used to withstand the impact force.

[0016] In one embodiment, the guide assembly further includes a locking member, which is mounted on a side of the guide shovel close to the first front shovel. A first locking portion is provided on a side of the first front shovel close to the guide shovel, and the locking member is locked in engagement with the first locking portion.

[0017] In one embodiment, a first positioning portion and a second positioning portion are respectively provided on a side where the guide shovel and the first front shovel are close to each other, and the first positioning portion is positioned and matched with the second positioning portion;

[0018] And / or, the guide assembly further comprises a second front shovel provided with a second locking portion, the structure and shape of the second locking portion being identical to those of the first locking portion, so that the locking member can be locked and matched with either the first locking portion or the second locking portion.

[0019] In one embodiment, the guide assembly further includes a rolling element, which is mounted on the first front shovel and is configured to be able to roll on the working surface.

[0020] On the other hand, a cleaning robot is provided, including a chassis, a side brush assembly, a roller brush assembly, a trash box and the garbage guide structure, the side brush assembly, the roller brush assembly, the trash box and the mounting base are all installed on the chassis, the upper edge of the guide assembly is located above the roller brush assembly or in contact with the roller brush assembly, the guide assembly is used to guide the garbage gathered by the side brush to the roller brush assembly, and the roller brush assembly is used to transfer the garbage into the trash box.

[0021] In the above-described embodiment, the garbage guide structure is used by attaching a mounting base to the chassis of the cleaning device. The guide assembly is mounted to the mounting base via a movable connection assembly. The guide assembly is tilted in the front-to-back direction, with its lower edge contacting the work surface and its upper edge above the work surface. This tilted orientation of the guide assembly allows it to guide garbage collected by the side brush assembly of the cleaning device to the roller brush assembly, where it is further reeled into a rear garbage bin. As the chassis of the device drives the garbage guide structure forward to perform cleaning operations, if it encounters an obstacle on the work surface, the obstacle exerts an impact force on the lower edge of the guide assembly, pushing the guide assembly backward and upward relative to the mounting base, increasing the distance between the guide assembly and the work surface to allow it to pass the obstacle. Once the guide assembly passes the obstacle, the impact force dissipates and the guide assembly returns to its initial position under the action of its own weight and the pressure of the side brush, ensuring that the guide assembly re-contacts the work surface and improving the cleaning efficiency of the cleaning robot. Compared to existing garbage guide structures, the guide assembly in this application is movably mounted on the mounting base. This allows the guide assembly to adjust the distance between itself and the working surface to pass through the obstacle when it collides with it. Furthermore, after passing the obstacle, the guide assembly can promptly return to its initial position under the action of its own gravity and / or the pressure of the side brush. In other words, the guide assembly is floatingly mounted on the mounting base and can adaptively adjust the distance between itself and the working surface according to the conditions of the working surface, thereby improving the garbage guide structure's ability to cross obstacles and surmount ridges. Therefore, the guide mechanism provided in this application can achieve both garbage guidance effectiveness and obstacle-crossing capability. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0032] like Figure 1 、 Figure 2 and Figure 3As shown, in one embodiment, a garbage guide structure 10 is provided for use in cleaning equipment. The garbage guide structure 10 includes a mounting base 100 and a guide assembly 200. The mounting base 100 is mounted on the chassis of the cleaning equipment; the guide assembly 200 is mounted on the mounting base 100 via a movable connection assembly; the guide assembly 200 is tilted in the front-to-back direction, with the lower edge of the guide assembly 200 contacting the working surface 20. When the lower edge 231 of the guide assembly 200 is impacted, the guide assembly 200 is pushed back and lifted upward relative to the mounting base 100; when the impact force disappears, the guide assembly 200 returns to its original position.

[0033] In the above-described embodiment, the garbage guide structure 10 is used by attaching the mounting base 100 to the chassis of the cleaning device. The guide assembly 200 is mounted to the mounting base 100 via a movable connection assembly. The guide assembly 200 is tilted in the front-to-back direction, with the lower edge of the guide assembly 200 contacting the working surface 20 and the upper edge of the guide assembly 200 being higher than the working surface 20. This tilted orientation of the guide assembly 200 ensures that garbage collected by the side brush assembly is directed to the roller brush assembly, where it is then swept into the rear garbage bin. As the chassis of the cleaning device drives the garbage guide structure 10 forward to perform cleaning operations, if it encounters an obstacle on the working surface 20, the obstacle will impact the lower edge 231 of the guide assembly 200, pushing the guide assembly 200 backward and upward relative to the mounting base 100. This increases the distance between the guide assembly 200 and the working surface 20 to allow it to pass through the obstacle. After the guide assembly 200 passes the obstacle, the impact force on the guide assembly 200 disappears, and the guide assembly 200 returns to its initial position under the action of its own weight and / or the pressure of the side brush. This ensures that the guide assembly 200 can re-contact the working surface 20, thereby improving the guiding and transfer effectiveness of the garbage guiding structure 10. Compared with garbage guiding structures in the prior art, the guide assembly 200 in the present application is movably mounted on the mounting base 100, allowing the guide assembly 200 to adjust the distance between itself and the working surface 20 to pass the obstacle when it collides with the obstacle. At the same time, after passing the obstacle, the guide assembly 200 can promptly return to its initial position under the action of its own weight and the pressure of the side brush. That is, the guide assembly 200 is floatingly mounted on the mounting base 100, and the guide assembly 200 can adapt to the conditions of the working surface 20 to adjust the distance between itself and the working surface 20, thereby improving the garbage guiding structure 10's ability to pass over bumps and obstacles. Therefore, the garbage guiding structure 10 provided in the present application can achieve both garbage guiding effectiveness and obstacle-crossing capabilities.

[0034] like Figure 1As shown, in this embodiment, the guide assembly 200 has a "shovel-like" structure, with a low center and high sides, and a narrow front and wide rear. The shovel-like design of the guide assembly 200 facilitates the guidance of debris collected by the side brush. Furthermore, the upper surface of the guide assembly 200 is provided with ribs 130 for guiding and collecting debris.

[0035] like Figure 2 As shown, specifically in this embodiment, the mounting base 100 includes a mounting body 140 and a roller brush front stop 150. The roller brush front stop 150 is mounted on the mounting body 140 and can form a part of the front wall of the roller brush compartment together with the mounting body 140 when the mounting body 140 is mounted on the chassis. It is understood that the mounting base 100 can be an integral part of the chassis, that is, the mounting base 100 forms a part of the equipment chassis.

[0036] like Figure 1 As shown, the garbage guide structure optionally further includes an elastic member 300, the ends of which are connected to the mounting base 100 and the guide assembly 200, respectively. The elastic member 300 is configured to stretch when the lower edge of the guide assembly 200 is subjected to an impact force, and to rebound and return to its original position when the impact force disappears. Thus, when the chassis drives the garbage guide structure 10 forward to perform cleaning operations and encounters an obstacle, the obstacle exerts an impact force on the lower edge 231 of the guide assembly 200, causing the guide assembly 200 to be pushed back and lifted relative to the mounting base 100. The elastic member 300 stretches, increasing the distance between the guide assembly 200 and the work surface 20 to allow it to pass through the obstacle. After the guide assembly 200 passes the obstacle, the impact force on the guide assembly 200 disappears, and the elastic member 300 recovers and drives the guide assembly 200 back to its original position. This ensures that the guide assembly 200 can more quickly and promptly return to its original position in contact with the work surface 20. When there are no obstacles on the work surface 20, this further ensures the effective guidance and transfer of the garbage guide structure 10.

[0037] It should be noted that when the garbage guide structure 10 does not encounter an obstacle, the guide assembly 200 will remain in the initial position under the control of the elastic member 300. The lower edge 231 refers to the direction of the guide assembly 200 (such as the direction of the guide assembly 200). Figure 2 In the direction shown in A in FIG, the guide assembly 200 is close to the side of the working surface 20. The upper edge 221 refers to the side of the guide assembly 200 away from the working surface 20 along the inclined direction of the guide assembly 200.

[0038] The mounting base 100 can be a one-piece structure or can be assembled from multiple parts. The elastic member 300 can be configured as a tension spring, elastic strip, elastic column, or other elastic connection. Specifically, in this embodiment, the elastic member 300 is configured as a tension spring and is located between the guide assembly 200 and the mounting base 100.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the movable connection assembly includes a first connecting rod 400 and a second connecting rod 500 spaced apart from each other. One end of the first connecting rod 400 and one end of the second connecting rod 500 are both hinged to the mounting base 100, and the other ends of the first connecting rod 400 and the other ends of the second connecting rod 500 are both hinged to the guide assembly 200. Thus, the mounting base 100, the first connecting rod 400, the guide assembly 200, and the second connecting rod 500 cooperate to form a linkage mechanism. With this arrangement, the movable connection assembly is configured as a linkage mechanism, and the first connecting rod 400 and the second connecting rod 500 can cooperate to guide and limit the guide assembly 200, ensuring that the guide assembly 200 floats within a preset travel range, thereby improving the reliability of the garbage guide structure 10.

[0040] Optionally, the guide assembly 200 has a center plane parallel to the vertical plane, and two first connecting rods 400 and two second connecting rods 500 are each symmetrically arranged about the center plane and located on opposite sides of the mounting base 100. In this manner, by increasing the number of connecting rod mechanisms, the floating of the guide assembly 200 is made more stable, thereby improving the reliability of the garbage guiding structure 10. Specifically, in this embodiment, the left and right sides of the guide assembly 200 are also symmetrically arranged about the center plane.

[0041] In other embodiments not shown in the accompanying drawings, in addition to using the linkage mechanism composed of the first link 400 and the second link 500 to movably connect the guide assembly 200 and the mounting base 100, the movable connection assembly can also be configured to rotatably mount the guide assembly 200 on the base 100 by a single or combined structure such as hinges, hinges and torsion springs.

[0042] Please combine Figure 2 In one embodiment, the mounting base 100 is provided with a first stopper 110, which is configured to engage with the guide assembly 200 when the guide assembly 200 is in its initial position. Thus, when the guide assembly 200 is reset, the first stopper 110 acts as a stopper, allowing the guide assembly 200 to quickly and accurately return to its initial position. This ensures that the guide assembly 200 can re-engage the working surface 20 without colliding with the working surface 20, thereby improving the reliability of the garbage guiding structure 10.

[0043] The first limiting portion 110 can be directly engaged with the guide assembly 200 for limiting position, or can be indirectly engaged with the guide assembly 200 for limiting position via the first connecting rod 400 or the second connecting rod 500. The first limiting portion 110 can be configured as a limiting surface, a limiting frame, or other limiting structure. Specifically, in this embodiment, the guide assembly 200 is provided with a third limiting portion 210, which is configured to engage with the first limiting portion 110 for limiting position when the guide assembly 200 rotates to the initial position. The third limiting portion 210 is configured as a limiting plate.

[0044] like Figure 1 and Figure 3 As shown, the mounting base 100 optionally includes a second stopper 120, which is configured to engage with the guide assembly 200 when the guide assembly 200 is raised to a preset position. Thus, when the guide assembly 200 is raised, the second stopper 120 can limit the maximum lift height of the guide assembly 200, ensuring that the guide assembly 200 can reciprocate within a preset stroke and pass through obstacles within a preset height range, thereby ensuring that the guide assembly 200 does not interfere with surrounding components and improving the reliability of the garbage guiding structure 10.

[0045] The preset position refers to the position at which the guide assembly 200 is lifted relative to the working surface 20 to a preset height (i.e., the maximum lifting height, such as Figure 3 When the height is set to the height shown in FIG. 1 (B), the position of the guide assembly 200 relative to the mounting base 100. The value of the preset height can be flexibly adjusted according to actual needs.

[0046] The second limiting portion 120 can be directly engaged with the guide assembly 200 for limiting position, or it can be indirectly engaged with the guide assembly 200 for limiting position through the first connecting rod 400 or the second connecting rod 500. The second limiting portion 120 can be configured as a limiting surface, a limiting groove, or other limiting structure. Specifically, in this embodiment, along the tilt direction of the guide assembly 200, the first connecting rod 400 is located above the second connecting rod 500. The second limiting portion 120 is configured to engage with the first connecting rod 400 for limiting position when the guide assembly 200 rotates to a predetermined position.

[0047] like Figure 1 and Figure 4 As shown, in one embodiment, the guide assembly 200 includes a guide shovel 220 and a first front shovel 230. The guide shovel 220 is rotatably mounted on the mounting base 100. The first front shovel 230 is detachably mounted to the front end of the guide shovel 220 along the tilt direction of the guide shovel 220 and is used to withstand impact forces. This allows the first front shovel 230 to be removed from the guide shovel 220 for easy replacement, extending the service life of the garbage guide structure 10.

[0048] The first front shovel 230 can be mounted on the lower side of the guide shovel 220 by means of snap connection, screw connection, plug connection or other detachable connection methods. Specifically in this embodiment, the guide shovel 220 is connected to the end of the elastic member 300 away from the mounting base 100.

[0049] like Figure 3 and Figure 4 As shown, the guide assembly 200 further includes a locking member 240, which is mounted on a side of the guide shovel 220 near the first front shovel 230. A first locking portion 232 is provided on the side of the first front shovel 230 near the guide shovel 220, and the locking member 240 is locked with the first locking portion 232. In this way, the first front shovel 230 can be fixed to the guide shovel 220 as a whole via the first locking portion 232 and the locking member 240, ensuring that the first front shovel 230 and the second front shovel 250 do not move relative to each other during use, thereby improving the reliability of the garbage guiding structure 10.

[0050] The locking member 240 can be configured as any locking structure. Specifically, in this embodiment, the first locking portion 232 can be integrally formed with the first front shovel 230. The locking member 240 can be mounted on the guide shovel 220 via a snap-on, screw-on, plug-on, or other connection method. The locking member 240 and the first locking portion 232 can cooperate to form a buckle, with the locking member 240 being the movable portion of the buckle and the first locking portion 232 being the fixed portion.

[0051] The number of locking members 240 and first locking portions 232 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, there are two locking members 240 and two first locking portions 232. The two locking members 240 are symmetrically arranged about the center plane and are located on the left and right sides of the guide shovel 220, respectively. The two first locking portions 232 are symmetrically arranged about the center plane and are located on the left and right sides of the first front shovel 230, respectively.

[0052] like Figure 4 As shown, optionally, a first positioning portion 222 and a second positioning portion 233 are respectively provided on the side of the guide shovel 220 and the first front shovel 230 adjacent to each other, and the first positioning portion 222 and the second positioning portion 233 are positioned and matched. In this way, after the first front shovel 230 is initially installed on the guide shovel 220 using the first positioning portion 222 and the second positioning portion 233, the first front shovel 230 and the guide shovel 220 are fixed together using the locking member 240 and the first locking portion 232, thereby improving the convenience of assembling the garbage guiding structure 10.

[0053] The first positioning portion 222 can be configured as a positioning post, a positioning block, or other positioning structure. The second positioning portion 233 can be correspondingly configured as a positioning hole, a positioning slot, or other positioning structure. The number of first positioning portions 222 and second positioning portions 233 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, two positioning holes are provided on the side of the guide shovel 220 proximate to the first front shovel 230, and two first positioning posts are provided on the side of the first front shovel 230 proximate to the guide shovel 220. The two first positioning posts are symmetrically arranged about the center plane and are positioned in correspondence with the two positioning holes.

[0054] like Figure 4 As shown, the guide assembly 200 optionally further includes a second front shovel 250 having a second locking portion 251. The structure and shape of the second locking portion 251 are identical to those of the first locking portion 232, so that the locking member 240 can be locked with either the first locking portion 232 or the second locking portion 251. In this way, the first front shovel 230 and the second front shovel 250 have the same mounting and locking structure, allowing the guide shovel 220 to interchangeably use the first front shovel 230 and the second front shovel 250 as needed, thereby improving the practicality of the garbage guiding structure 10.

[0055] The first front shovel 230 and the second front shovel 250 can be two different front shovels with different maximum lift heights relative to the work surface 20, or can be two different front shovels with different rubber hardnesses. In other embodiments, the number of front shovel types can be flexibly adjusted based on actual usage needs, as long as each type of front shovel has the same mounting and locking structure to be locked and fixed to the guide shovel 220.

[0056] Specifically in this embodiment, the second front shovel 250 is further provided with two second positioning posts, the structure and shape of the second positioning posts being identical to those of the first positioning posts, and the two second positioning posts being positioned and matched with the two positioning holes.

[0057] like Figure 1 and Figure 4 As shown, in one embodiment, the guide assembly 200 further includes a rolling member 260. The rolling member 260 is mounted on the first front shovel 230 and is configured to roll on the work surface 20. With this arrangement, the rolling surface of the rolling member 260 constitutes the lower edge of the guide assembly 200. While rolling on the work surface 20, the rolling member 260 can also limit the position of the first front shovel 230. This ensures that the distance between the first front shovel 230 and the work surface 20 remains stable when no obstacles are encountered, while also reducing the friction of the guide assembly 200 on the work surface 20.

[0058] Specifically, in this embodiment, the rolling elements 260 are configured as two rollers, symmetrically arranged about the center plane and mounted on the left and right sides of the first front shovel 230. The symmetrical arrangement of the two rolling elements 250 ensures the stability of the entire garbage guide structure 10 and prevents it from tilting. It should be noted that by replacing the rollers (rolling elements 260) with different diameters, the height of the guide assembly 200 above the ground in its initial position can be adjusted to accommodate different working conditions of the working surface 20.

[0059] Please combine Figure 5 In one embodiment, a cleaning robot is provided, comprising a chassis (not shown), a side brush assembly 30, a roller brush assembly 40, a trash box 50, and the trash guide structure 10 of any of the above embodiments. The side brush assembly 30, the roller brush assembly 40, the trash box 50, and the mounting base 100 are all mounted on the chassis. The upper edge of the guide assembly 200 is located above the roller brush assembly. The guide assembly 200 is used to guide the garbage gathered by the side brush assembly 30 to the roller brush assembly 40, and the roller brush assembly 40 is used to transfer the garbage to the trash box 50. The cleaning robot provided in this embodiment does not require an additional fan for sucking out garbage. The garbage on the working surface 20 can be collected into the trash box 50 through the cooperation of the side brush assembly 30, the garbage guide structure 10, and the roller brush assembly 40, thereby saving material costs and avoiding the huge noise generated by the suction fan when it is working.

[0060] When the cleaning robot of the above embodiment is used, the mounting base 100 is mounted on the chassis of the cleaning robot, and the guide assembly 200 is mounted on the mounting base 100 via a movable connection assembly. The guide assembly 200 is tilted in the front-to-back direction, that is, the lower edge of the guide assembly 200 contacts the working surface, and the upper edge of the guide assembly 200 is higher than the working surface. The lower edge 231 of the guide assembly 200 contacts the working surface 20, ensuring that the guide assembly 200 can guide garbage from the working surface 20 to the guide assembly 200. The upper edge of the guide assembly 200 is higher than the working surface, ensuring that the guide assembly 200 can guide the garbage to the roller brush assembly, and then the roller brush assembly transfers the garbage into the garbage bin. When the cleaning robot's chassis drives the garbage guide structure 10 forward to perform cleaning operations and encounters an obstacle, the obstacle will exert an impact force on the lower edge 231 of the guide assembly 200. Because the guide assembly 200 and the mounting base 100 are movably connected via an articulating assembly, the guide assembly 200 is pushed back and lifted relative to the mounting base 100, increasing the distance between the guide assembly 200 and the working surface 20 to enable the robot to pass the obstacle. After the guide assembly 200 passes the obstacle, the impact force on the guide assembly 200 disappears, and the guide assembly 200 returns to its initial position under the action of its own weight and / or the pressure of the side brush assembly, ensuring that the guide assembly 200 can re-contact the working surface 20, thereby improving the cleaning effect of the cleaning robot. Compared with the prior art, the guide assembly 200 in the present application is movably mounted on the mounting base 100, so that when the guide assembly 200 collides with an obstacle, it can adjust the distance between itself and the working surface 20 to pass the obstacle. At the same time, after passing the obstacle, the guide assembly 200 can be promptly reset to its initial position under the action of its own gravity and / or the pressure of the side brush assembly 30. That is, the guide assembly 200 is floatingly mounted on the mounting base 100, and the guide assembly 200 can adjust the distance between itself and the working surface 20 according to the situation of the working surface 20, thereby improving the cleaning robot's ability to cross obstacles and hurdles. Therefore, the guide mechanism 10 and cleaning robot provided in the present application can take into account both the garbage guidance and storage effect and the obstacle-crossing ability.

[0061] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0062] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0063] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0064] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0065] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, 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 embodiment.

[0066] It should also be understood that when explaining the connection relationship or positional relationship of elements, even if not explicitly described, the connection relationship and positional relationship should be interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately," "approximately," or "substantially" can mean within one or more standard deviations, which is not limited here.

[0067] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.

[0068] The above embodiments merely illustrate several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
