Description

Technical Field

[0001] This application relates to the field of dry bulk material transportation equipment technology, and in particular to a material transportation equipment and its material transportation device. Background Technology

[0002] Dry bulk materials refer to bulk solid materials such as gravel, cement, and pulverized coal, which are widely used in industries such as construction and agriculture. The transportation of dry bulk materials is a critical link in the supply chain of related industries, directly affecting construction efficiency and production costs.

[0003] In existing technologies, the transportation of dry bulk materials mainly relies on two methods. One method is to rely on rail transport. When the track gauge changes, the vehicle body and related structures need to be modified. The loading and unloading process is limited by the track laying conditions and cannot flexibly switch between road and rail transport modes. The other method is to rely on dedicated road transport vehicles. However, the limited variety of vehicle types leads to insufficient emergency response capabilities, and the fixed unloading structure is difficult to adapt to different construction needs, thus limiting loading and unloading efficiency. Summary of the Invention

[0004] In view of the above problems, this application provides a material transport equipment and a material transport device, which has strong adaptability, high loading and unloading efficiency, and can achieve precise quantitative unloading.

[0005] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] In one possible implementation, the fixing component includes multiple legs spaced apart along the length of the hopper, with the top ends of the legs connected to the hopper and the bottom ends of the legs detachably connected to the transport platform.

[0008] In one possible implementation, the fixing component includes multiple legs, which are respectively arranged on opposite sides of the discharge port along the width direction, and the multiple legs are spaced apart along the length direction of the hopper. The top ends of the multiple legs are connected to the hopper, and the bottom ends of the multiple legs are detachably connected to the transport platform.

[0009] In one possible implementation, the outrigger is configured to insert into a limiting hole provided on the transport platform.

[0010] In one possible implementation, the hopper includes vertical walls, inclined walls, and a bottom wall; the two vertical walls are opposite each other and spaced apart in the width direction; the bottom ends of the two vertical walls are respectively connected to an inclined wall; along the height direction of the hopper, from top to bottom, the two inclined walls are inclined towards each other; the bottom wall is connected to the bottom ends of the two inclined walls.

[0011] In one possible implementation, the top of the fixing component is connected to the top of the outer side of the inclined wall.

[0012] In one possible implementation, the hopper is provided with multiple lifting lugs on both sides along its width direction, and the multiple lifting lugs are arranged at intervals along the length direction of the hopper.

[0013] In one possible implementation, guide ramps are provided on both sides of the discharge port along the length of the hopper; along the height of the hopper, from top to bottom, the guide ramps are inclined toward the discharge port; the tops of the two guide ramps between two adjacent discharge ports are connected; along the height of the hopper, from top to bottom, the distance between the two guide ramps between two adjacent discharge ports increases.

[0014] In one possible implementation, the discharge switch assembly includes: a fixing member located on the side of the discharge port and fixedly connected to the hopper; a sliding plate slidably connected to the fixing member and having a plurality of second through holes; when each discharge port is opposite to one of the second through holes, the discharge port is configured to be open; when the plurality of discharge ports are staggered from the plurality of second through holes, the discharge port is opposite to the sliding plate, so that the discharge port is configured to be closed.

[0015] In one possible implementation, the sliding plate slides along the length of the hopper.

[0016] Another aspect of this application provides a material transport device, including: a material transport apparatus as described above; and a transport platform detachably connected to the material transport apparatus.

[0017] The material transport equipment and device provided in this application include a hopper, a discharge switch assembly, and a fixing assembly. The hopper is constructed to form a cavity for containing materials, and its bottom is provided with multiple discharge ports. The discharge switch assembly is located at the bottom of the discharge ports and can control the opening and closing state of each discharge port, thereby achieving precise control of the discharge position and discharge amount, and meeting the quantitative discharge requirements under different construction scenarios.

[0018] The top of the fixed component connects to the hopper, while the bottom is designed for detachable connection to different transport platforms. This allows the material handling device of this application to flexibly adapt to various transport modes, such as road and rail, expanding its application scope and scenario adaptability. When the fixed component is connected to the transport platform, an appropriate discharge gap is maintained between the bottom of the discharge port and the transport platform to provide necessary space for smooth material discharge, avoiding blockages or interference during unloading and ensuring the continuity and reliability of loading and unloading operations. Therefore, the material handling device provided by this application has advantages such as strong adaptability, high loading and unloading efficiency, and the ability to achieve precise quantitative unloading.

[0035] As described in the background section, dry bulk materials are granular or powdery materials widely used in fields such as construction, agriculture, and urban subway tunnel construction. Their transportation efficiency and stability are directly related to the construction progress and production continuity, thus requiring specialized transportation equipment to adapt to the transportation needs of different scenarios.

[0036] Currently, common methods of transporting dry bulk materials are mainly divided into two categories. One type relies on rail-based transport vehicles, which lack independent power and require locomotive traction. Loading and unloading are limited by track laying conditions. When the track gauge changes in the construction area, the vehicle and container structures must be modified accordingly, resulting in poor adaptability. Furthermore, this method is only suitable for railway transport and cannot achieve flexible switching between road and rail transport. The vehicle type has limited functionality and cannot meet the diverse needs of different construction stages or material types.

[0037] Another method uses dedicated highway transport vehicles, which are self-powered but limited in variety. When faced with emergency transport tasks, difficulties in vehicle allocation can lead to insufficient responsiveness. Furthermore, their fixed unloading structure prevents adjustments to the unloading port configuration according to on-site construction needs, thus hindering loading and unloading efficiency.

[0038] In summary, existing technical solutions are all limited by a single transportation mode, failing to integrate the advantages of road and rail transport, thus restricting transportation flexibility and making it difficult to adapt to the requirements of efficient transportation in complex terrain and variable construction environments. Furthermore, existing dry bulk material transport devices generally lack precise quantitative unloading control mechanisms, failing to meet the stringent requirements of uniform material distribution and quantity control at construction sites, thereby further restricting the overall adaptability, efficiency, and stability of dry bulk material transport.

[0039] In view of this, embodiments of this application provide a material transport equipment and a material transport device thereof.

[0040] One aspect of this application provides a material transport device, which includes a hopper and a fixing component. The top of the fixing component is connected to the hopper, and the fixing component is configured to be detachably connected to a transport platform. By setting a detachably connected fixing component, the same hopper can be adapted to different transport platforms, enabling switching between road and rail transport without modifying the main body of the hopper. This overcomes the limitations of a single transport mode and avoids the need to modify the overall structure of the material transport device when the track gauge changes, thereby improving the adaptability of the material transport device of this application.

[0041] In addition, multiple discharge ports are provided at the bottom of the hopper. The material conveying device of this application also includes a discharge switch assembly, which is located at the bottom of the discharge ports and is configured to control the opening and closing of the multiple discharge ports. By adjusting the opening and closing state of each discharge port through the discharge switch assembly, the unloading amount can be adjusted as needed to achieve quantitative unloading, thus solving the shortcomings of low unloading efficiency and insufficient control precision in existing methods. A discharge gap is maintained between the bottom of the discharge port and the conveying platform, providing the necessary space for smooth material unloading and ensuring that the material conveying device can achieve efficient and unobstructed unloading operations on different conveying platforms.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Figure 1 This is a schematic diagram of the material transport device provided in an embodiment of this application. Figure 2 A side view of a material transport device provided in an embodiment of this application. Figure 3 A top view of a material transport device provided in an embodiment of this application.

[0044] Reference Figure 1 This application provides a material handling equipment that can be widely applied to various material handling scenarios. For example, the equipment can be used in urban subway tunnel construction to achieve efficient and precise transport of backfill materials such as gravel in tunnels with complex geological conditions. It can also be used in road logistics to meet the transportation needs of building materials such as cement and pulverized coal, addressing urgent supply tasks and challenges in complex road conditions. Furthermore, the equipment can be used in multimodal transport systems requiring road-rail connections, enabling seamless material transfer between different transport modes and significantly improving overall transportation efficiency across regions and scenarios.

[0045] The above is merely an illustrative description of the application scenarios of the material transport equipment in the embodiments of this application, and is not intended to limit the application scenarios of the material transport equipment in the embodiments of this application.

[0046] Reference Figure 1 , Figure 2 and Figure 3 The material transport equipment includes a transport platform (not shown in the figure) and a material transport device 10. The transport platform and the material transport device 10 are detachably connected. This configuration allows the material transport device 10 to be adapted to transport platforms of different specifications, enabling flexible switching between road and rail transport modes.

[0047] The detachable connection between the transport platform and the material transport device 10 enhances the organizational flexibility of the material transport equipment, allowing it to select the optimal transport plan based on actual working conditions and improving the utilization rate of the material transport device 10. Furthermore, when the transport platform requires maintenance, the material transport device 10 can be quickly detached and put back into operation, thus ensuring the continuity and efficiency of transport operations.

[0048] Reference Figure 1 The material conveying device 10 includes a hopper 100, which is configured to form a cavity for containing materials.

[0049] The top of the container can be open. This facilitates quick and efficient loading operations and allows for easy observation of the material's condition within the container, thus improving loading efficiency and operational convenience.

[0050] Figure 4 This is a schematic diagram of the structure of the hopper in the material transport device provided in the embodiments of this application. Figure 5 This is a top view of the hopper in a material conveying device provided in an embodiment of this application. (Refer to...) Figure 4 and Figure 5 In some embodiments, the hopper 100 may use standard channel steel to form its main load-bearing frame 100a, and weld steel plates 100b of a certain thickness around the inside and bottom of the frame 100a. In this way, the combination of the channel steel frame 100a and the steel plates 100b can ensure that the hopper 100 has excellent rigidity and strength, and can reliably withstand the static load of the material it carries as well as the dynamic load impact generated under complex transportation conditions, thereby ensuring the structural integrity and stability during transportation.

[0051] Continue to refer to Figure 4 and Figure 5 Multiple discharge ports 110 can be provided at the bottom of the hopper 100. Multiple discharge ports 110 allow materials to be discharged from multiple positions simultaneously, avoiding the problem of uneven material accumulation caused by a single discharge port, and improving discharge efficiency and quality.

[0052] In some embodiments, multiple discharge ports 110 can be spaced apart along the length of the cavity. This allows the layout of the multiple discharge ports 110 to adapt to the length of the cavity, enabling simultaneous unloading at multiple points along the length of the cavity, avoiding uneven material accumulation, and thus improving unloading efficiency and uniformity.

[0053] Figure 6 This is a side view of the hopper in a material conveying device provided in an embodiment of this application. (Refer to...) Figure 6 The hopper 100 may include vertical walls 120, inclined walls 130, and a bottom wall 140. Two vertical walls 120 are opposite each other along their width and are spaced apart. The bottom ends of each of the two vertical walls 120 are connected to an inclined wall 130. Along the height direction of the hopper 100, from top to bottom, the two inclined walls 130 are inclined towards each other. The bottom wall 140 is connected to the bottom ends of the two inclined walls 130.

[0054] Additionally, refer to Figure 5 The hopper 100 may also include two end walls 150, which are respectively disposed at both ends of the vertical wall 120 along its length. The two end walls 150 are respectively connected to the vertical wall 120 and the inclined wall 130, together forming a cavity.

[0055] To accommodate the lifting and relocation needs of the hopper 100 in construction or transportation scenarios, multiple lifting lugs can be installed on both sides of the hopper 100 along its width direction, with the lugs spaced apart along the length direction of the hopper 100. Each lifting lug can be firmly connected to the hopper 100 by welding to ensure the connection strength between the lug and the hopper 100, thereby ensuring the stability and structural safety of the hopper 100 during the lifting process and meeting the operational requirements for lifting and transporting the hopper 100.

[0056] In some embodiments, lifting lugs can be connected to the vertical wall 120 or the end wall 150, and multiple lifting lugs can be distributed circumferentially along the vertical wall 120 and the end wall 150. In this way, the force-bearing surfaces of the end wall 150 and the vertical wall 120 are flat, which can provide a stable support foundation for the lifting lugs, and is conducive to improving the force balance and operational safety of the hopper 100.

[0057] An inclined wall 130 is disposed between the vertical wall 120 and the bottom wall 140. The inclined wall 130 extends inclinedly along the material flow direction, and its inclined structure guides the material in the cavity to flow naturally along the wall towards the bottom wall 140, preventing material accumulation within the cavity. The bottom wall 140 is connected to the bottom end of the inclined wall 130 and is provided with multiple discharge ports 110. Material in the cavity, guided by the inclined wall 130, can be discharged through the discharge ports 110 of the bottom wall 140.

[0058] In addition, since the bottom wall 140 is the main load-bearing structure of the hopper 100, it needs to bear the load of the material in the cavity, so it needs to have the corresponding structural strength to ensure that it does not deform or get damaged under load.

[0059] For example, refer to Figure 6 A bottom reinforcing plate 160 can be fixedly installed below the bottom wall 140. The bottom reinforcing plate 160 is connected to the bottom wall 140 and can distribute the material load borne by the bottom wall 140, preventing deformation of the bottom wall 140 due to localized stress concentration. At the same time, the bottom reinforcing plate 160 has a first through hole aligned with the discharge port 110. The position and diameter of the first through hole match the discharge port 110. This ensures that when the material is discharged from the cavity through the discharge port 110, it can smoothly pass through the first through hole without being blocked by the bottom reinforcing plate 160, thus ensuring the continuity of the unloading process.

[0060] Reference Figure 5 The bottom wall 140 can also be welded with a bottom reinforcing rib plate 170. The bottom reinforcing rib plate 170 can be distributed along the length of the bottom wall 140, thereby further enhancing the structural rigidity of the bottom wall 140 and improving the overall deformation resistance of the bottom wall 140.

[0061] Additionally, refer to Figure 4 Along the length of the hopper 100, guide ramps 180 can be provided on both sides of the discharge port 110. Along the height of the hopper 100, from top to bottom, the guide ramps 180 slope towards the discharge port 110, forming a flow channel that converges towards the discharge port 110. The tops of the two guide ramps 180 between two adjacent discharge ports 110 are connected. Furthermore, along the height of the hopper 100 from top to bottom, the distance between the two guide ramps 180 between two adjacent discharge ports 110 increases along the length direction.

[0062] This configuration ensures that the material in the upper part of the cavity can be smoothly transferred to the discharge port 110 through the guide plate 180, avoiding the formation of dead corners between adjacent discharge ports 110, and allowing the material to flow to the corresponding discharge ports 110 on both sides, further ensuring the continuity and smoothness of material discharge during the unloading process.

[0063] Meanwhile, the guide plate 180 and the inclined wall 130 work together to form a guide channel that gradually narrows from top to bottom, allowing the material to flow naturally along the guide channel under the action of gravity, avoiding material stagnation or accumulation in the cavity, thereby achieving smooth material flow, uniformity of the unloading process, and improved unloading efficiency.

[0064] Reference Figure 6In some embodiments, triangular ribs 190 can be provided on the outer side of the guide ramp 180, and the triangular ribs 190 are connected to both the guide ramp 180 and the bottom wall 140. Utilizing the geometric stability of the triangular structure, the triangular ribs 190 can create a reliable rigid connection between the guide ramp 180 and the bottom wall 140 of the hopper 100, improving the connection strength between the guide ramp 180 and the bottom wall 140, and suppressing potential loosening or fatigue cracking of the connection portion of the guide ramp 180 under long-term alternating loads.

[0065] Meanwhile, the triangular rib plate 190 can distribute and transfer the material impact load and its own weight borne by the guide plate 180 to the bottom wall 140 and bottom reinforcing plate 160 of the hopper 100, thereby reducing the stress concentration of the guide plate 180 and ensuring the long-term reliability of the guide plate 180.

[0066] In addition, multiple guide ribs (not shown in the figure) can be provided on the surface of the guide sloping plate 180. The multiple guide ribs extend along the material flow direction, which can further enhance the bending stiffness and deformation resistance of the guide sloping plate 180 itself, and prevent the guide sloping plate 180 from local dents or bending due to long-term material flow and compression.

[0067] Figure 7 A side view of the discharge switch assembly in the material transport device provided in an embodiment of this application. (Refer to...) Figure 7 The material transport device 10 also includes a discharge switch assembly 200, which is located at the bottom of the discharge port 110. It can control the opening and closing of multiple discharge ports 110 according to actual unloading needs, thereby regulating the unloading area and material flow.

[0068] Continue to refer to Figure 7 In some embodiments, the discharge switch assembly 200 may include a fixing member 210 and a sliding plate 220. The fixing member 210 is located on the side of the discharge port 110 and is fixedly connected to the hopper 100. The fixing member 210 can provide a mounting base and sliding guide for the sliding plate 220.

[0069] For example, the fastener 210 can be bolted to the bottom reinforcing plate 160 of the hopper 100 to ensure that the sliding plate 220 maintains a stable movement trajectory during long-term use, and to prevent the sliding plate 220 from getting stuck or misaligned due to the displacement of the fastener 210, thereby ensuring the accuracy and reliability of the opening and closing control of the discharge port 110.

[0070] Of course, the fastener 210 can also be fixedly connected to the bottom reinforcing plate 160 by welding or bayonet connection. This application embodiment does not impose specific limitations on this.

[0071] Figure 8This is a schematic diagram of the sliding plate in the material transport device provided in an embodiment of this application. (Refer to...) Figure 8 The sliding plate 220 is slidably connected to the fixing member 210. The sliding plate 220 is provided with a plurality of second through holes 221, the number and spacing of which are adapted to the number of discharge ports 110. When the sliding plate 220 moves to a specific position, each discharge port 110 is opposite to one of the through holes, and the discharge port 110 is in the open state, allowing material to pass smoothly. When the sliding plate 220 moves to another position, the multiple discharge ports 110 are staggered from the multiple through holes, and the discharge ports 110 are opposite to the sliding plate 220, at which point the discharge ports 110 are configured to be closed, blocking the material discharge path.

[0072] In addition, by moving the sliding plate 220, the overlapping area of ​​the second through hole 221 and the discharge port 110 can be adjusted, thereby adjusting the opening of the discharge port 110. In this way, the operator can control the displacement of the sliding plate 220 to achieve the effective flow section of the discharge port 110 according to the construction requirements, thereby controlling the material unloading rate and improving the applicability of the material conveying device 10.

[0073] In some possible embodiments, the sliding plate 220 can slide along the length of the hopper 100. Furthermore, the sliding plate 220 can be an elongated structure with a row of second through holes 221 corresponding to the discharge ports 110. By sliding the sliding plate 220 linearly along its length, the opening or closing of all discharge ports 110 can be controlled synchronously, making operation simple and the transmission mechanism simple and reliable.

[0074] In other possible embodiments, the sliding plate 220 can also slide along the width direction of the hopper 100. Based on this, the sliding plate 220 can be a single integrated structure, or multiple independently controlled sliding plate 220 units can be provided, arranged along the length direction of the hopper 100. When there are only multiple sliding plate 220 units, each sliding plate 220 unit can independently control one or more discharge ports 110 in its corresponding area. This configuration allows operators to selectively open the discharge ports 110 in specific areas according to site requirements, achieving targeted material delivery and improving the flexibility of the material transport device 10.

[0075] In addition, the movement of the sliding plate 220 can be achieved by manual control. An operating handle 222 can be provided at the end of the sliding plate 220 along the length direction of the hopper 100. The operator can directly push and pull the operating handle 222 to drive the sliding plate 220 to slide, thereby completing the position adjustment of the sliding plate 220.

[0076] Alternatively, the movement of the sliding plate 220 can also be achieved through electric control. The discharge switch assembly 200 may further include a drive motor, a transmission mechanism, and a control unit, wherein the drive motor converts the rotational motion into linear displacement of the sliding plate 220 through the transmission mechanism. The control unit can receive remote signals or preset program instructions to achieve precise adjustment and automated operation of the discharge port 110 opening. The transmission mechanism may adopt transmission forms including but not limited to gear and rack mechanisms, chain drive mechanisms, belt drive mechanisms, or lead screw and nut mechanisms, and this application embodiment does not impose specific limitations on this.

[0077] Continue to refer to Figure 1 The material transport device 10 also includes a fixing component 300, the top of which is connected to the hopper 100 and detachably connected to the transport platform, so that the material transport device 10 can be quickly installed on different types of transport platforms.

[0078] Figure 9 This is a schematic diagram of the support leg in the material transport device provided in an embodiment of this application. (Refer to...) Figure 9 The fixing component 300 may include multiple support legs 310, which are spaced apart along the length of the hopper 100 and distributed on both sides of the hopper 100 along its width. The tops of the support legs 310 are connected to the hopper 100. The tops of the support legs 310 may be fixed to the top of the outer side of the inclined wall 130. In this way, the support legs 310 can avoid the discharge area of ​​the discharge port 110, ensuring that the material flow path at the discharge port 110 is unobstructed.

[0079] For example, the support leg 310 can be connected to the outside of the inclined wall 130 by welding, and the top of the support leg 310 can be set as an inclined surface 311 adapted to the surface of the inclined wall 130, so as to obtain the maximum contact area and the best force transmission efficiency.

[0080] The outrigger 310 may be equipped with load-bearing stiffeners 312. The stiffeners 312 can distribute the weight load of the hopper 100 and the material within the cavity borne by the outrigger 310, preventing bending, deformation, or even breakage of the outrigger 310 due to localized stress concentration, thus ensuring stable support of the hopper 100 by the outrigger 310. Furthermore, during the transportation process of the material handling equipment, the stiffeners 312 can enhance the impact resistance and fatigue resistance of the outrigger 310, extending its service life and providing a stable structural foundation for the detachable connection of the material handling device 10 to adapt to different transportation platforms.

[0081] In addition, the bottom ends of multiple outriggers 310 are detachably connected to the transport platform. This design allows the material transport device 10 to quickly adapt to different types or specifications of transport platforms, such as those for highways and railways, without requiring modifications to the main structure, enabling flexible switching between transport modes. When the transport platform requires maintenance, the material transport device 10 can be quickly detached to continue operation, ensuring continuity of transport work. Furthermore, the detachable connection of the outriggers 310 to the transport platform simplifies the assembly and disassembly process, shortens platform changeover time, and further improves overall operational efficiency and device versatility.

[0082] In some embodiments, a limiting hole may be provided at a corresponding position on the transport platform. The bottom end of the outrigger 310 is provided with a plug-in portion 313 that matches the limiting hole. The plug-in portion 313 can be inserted vertically into the limiting hole to form a positioning fit. The fit between the limiting hole and the plug-in portion 313 enables rapid positioning of the outrigger 310 and the transport platform, reducing assembly alignment time.

[0083] To enhance the connection stability between the outrigger 310 and the transport platform, the cross-sectional dimensions and wall thickness of the insertion portion 313 can be increased to improve its bending stiffness and load-bearing capacity. Furthermore, by increasing the contact area between the insertion portion 313 and the transport platform, the load transfer path can be optimized, enhancing the fatigue resistance of the outrigger 310 under complex working conditions and improving the durability of the material transport device 10.

[0084] In other embodiments, the outrigger 310 and the transport platform can also be connected by snap-fit. The bottom end of the outrigger 310 may be provided with an elastic snap-fit, and the corresponding position on the transport platform is provided with a slot adapted to the snap-fit. During assembly, quick fixing is achieved by the snap-fit ​​between the elastic snap-fit ​​and the slot; during disassembly, pressing the release end of the snap-fit ​​disengages the connection. This application does not impose specific limitations on the connection method between the outrigger 310 and the transport platform, as long as a detachable connection between the outrigger 310 and the transport platform can be achieved.

[0085] It should be noted that when the fixed component 300 is connected to the transport platform, there is a discharge gap between the bottom end of the discharge port 110 and the transport platform. This ensures that the material flow can pass through the discharge port 110 without obstruction and be smoothly guided into the designated receiving device or area. This avoids interference from the transport platform in the unloading process and ensures the smooth flow of materials.

[0086] It should be noted that the terms "an embodiment," "an embodiment," "an exemplary embodiment," "some embodiments," etc., mentioned in the specification may include specific features, structures, or characteristics, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Additionally, when describing a specific feature, structure, or characteristic in conjunction with embodiments, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0087] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "one" can be understood to convey either singular or plural usage.

[0088] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0089] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
