Description

Technical Field

[0001] The present application relates to the technical field of material conveying, and in particular to a conveying device. Background Art

[0002] At present, the loading and unloading of goods by logistics companies are mainly done manually. In the express delivery industry, loading and unloading of goods are done manually with telescopic cranes. For the express delivery industry and large-scale logistics, the situation is even worse. It can only be done by manpower and forklifts. Loading and unloading are inconvenient. It takes 3-5 hours to load and unload each vehicle. The turnover time is long, the site is large, and the logistics cost is high. During the loading and unloading process, the length of the conveying equipment cannot be adjusted adaptively. Summary of the invention

[0003] The embodiment of the present application provides a conveying device to improve the problem of difficulty in loading and unloading goods in the current logistics industry.

[0004] The embodiment of the present application provides a conveying device, including a support platform and a flexible conveying mechanism. The flexible conveying mechanism includes a flexible conveying member and a transmission wheel, the transmission wheel is installed on the support platform, the front end of the flexible conveying member is used to connect with a traction device, and the rear end of the flexible conveying member bypasses the transmission wheel. The traction device can pull the front end of the flexible conveying member to move forward and backward on the support platform.

[0005] In the above technical solution, the front end of the flexible conveyor can move under the traction of the traction device, so that the goods placed on the flexible conveyor can move with the movement of the flexible conveyor under the traction of the traction device, and can transport the goods to the loading and unloading space reached by the traction device, reducing the manual handling of the goods. Similarly, if unloading is to be carried out, the traction device pulls the head flexible conveyor to the place to be unloaded, and places the goods on the flexible conveyor. The traction device drives one end of the flexible conveyor line to move in the unloading direction to achieve unloading, reducing the manual handling of the unloading process. In addition, the traction device pulls the front end of the flexible conveyor to move so that the working length of the flexible conveyor can adapt to the distance change between the cargo storage point and the cargo delivery target position. In addition, the flexible conveyor bypasses the transmission wheel, and the flexible conveyor has a turn at the rotating wheel, so that the turn of the flexible conveyor can always be docked with other equipment. In the process of the traction device pulling the flexible conveyor, the goods can be loaded or unloaded from the flexible conveyor, ensuring the continuity of transportation and improving the efficiency of cargo transportation.

[0006] In addition, the conveying device of the embodiment of the present application also has the following additional technical features:

[0007] In some embodiments of the present application, the flexible conveying member is a chain or a chain plate, and the transmission wheel is a sprocket.

[0008] In the above technical solution, the flexible conveying member can be a chain or a chain plate, and the chain or chain plate cooperates with the sprocket to enable the chain or chain plate to move stably relative to the supporting platform to ensure smooth and smooth transportation. At the same time, the setting of the sprocket can also prevent the chain or chain plate from moving randomly.

[0009] In some embodiments of the present application, the chain or the chain plate includes a supporting roller, and the chain or the chain plate is supported on the supporting platform through the supporting roller.

[0010] In the above technical solution, the chain or chain plate is supported on the supporting platform by supporting rollers, and the movement of the chain or chain plate relative to the supporting platform is achieved by rotating the supporting rollers relative to the supporting platform. This can reduce the friction between the chain or chain plate and the supporting platform during the movement process, and can use a smaller traction force to achieve the movement of the chain or chain plate, while also increasing the service life of the chain or chain plate.

[0011] In some embodiments of the present application, the conveying equipment also includes a winding mechanism, which is arranged on the supporting platform; the flexible conveying member is a conveyor belt, the transmission wheel is a roller shaft, the front end of the conveyor belt is connected to the traction device, and the rear end of the conveyor belt is connected to the winding mechanism; when the traction end moves along the loading direction, the winding mechanism winds up the conveyor belt, and when the traction end moves along the unloading direction, the winding mechanism releases the conveyor belt.

[0012] In the above technical solution, the conveyor belt is a flexible member, one end of the conveyor belt is used for traction by the traction device, and the other end is used for winding by the winding mechanism. When moving in the loading direction, the main power is provided by the traction device, and when moving in the unloading direction, the main power is provided by the winding mechanism. One end is pulled and the other end is wound so that the conveyor belt is always in a tensioned state, avoiding the accumulation of the conveyor belt due to pulling and winding, thereby ensuring smooth transportation.

[0013] In some embodiments of the present application, the transmission wheel divides the flexible conveyor into two parts, the part between the traction device and the transmission wheel is located on the support surface of the support platform, and the other part is located below the support surface of the support platform.

[0014] In the above technical solution, the part of the flexible conveyor supported on the supporting surface is convenient for placing and transporting goods, and the other part is located below the supporting surface to avoid mutual interference between the two ends of the flexible conveyor.

[0018] In the above technical solution, the setting of the first roller can ensure that the goods placed on the first roller can still be transported under the action of the first roller when the traction device does not provide traction.

[0024] In the above technical solution, the jacking mechanism includes a cross structure and a hydraulic cylinder. The cross structure can provide a certain supporting force for the supporting platform, avoiding that the supporting platform is supported by the hydraulic cylinder alone, thereby reducing the burden on the hydraulic cylinder.

[0025] In some embodiments of the present application, the lifting mechanism includes two cross structures arranged at intervals in a direction perpendicular to the conveying direction of the flexible conveying mechanism.

[0026] In the above technical solution, the jacking mechanism includes two cross structures, which can improve the stability of the jacking process. The two cross structures jointly share the load of the supporting platform, further reducing the load of the hydraulic cylinder.

[0027] In some embodiments of the present application, the conveying device further includes a fixed conveying mechanism, and a front end of the fixed conveying mechanism is used to dock with a turning portion of the flexible conveying mechanism.

[0028] In the above technical solution, the front end of the fixed conveying mechanism is connected with the turning point of the flexible conveying mechanism, so that the fixed conveying mechanism can continuously convey goods to the flexible conveying mechanism or the goods on the flexible conveying mechanism can be continuously conveyed to the fixed conveying mechanism, thereby improving the conveying efficiency. In addition, the traction device pulls the front end of the flexible conveying member to move so that the working length of the flexible conveying member can adapt to the distance change between the fixed conveying mechanism and the target location of the goods to be transported.

[0029] In some embodiments of the present application, the fixed conveying mechanism includes a first conveying mechanism and a second conveying mechanism, the front end of the first conveying mechanism is used to dock with the turning point of the flexible conveying mechanism, and the rear end of the first conveying mechanism is used to dock with the second conveying mechanism; the second conveying mechanism includes a transmission mechanism and an information collection device arranged on the transmission mechanism, and the transmission mechanism is used to transport the goods to the information collection device and transport the goods for which information has been collected to the first conveying mechanism.

[0031] In some embodiments of the present application, the first conveying mechanism includes a frame and a plurality of second rollers spaced apart from the frame, each second roller being rotatably disposed on the frame; the rotation of the second rollers can convey the goods on the first conveying mechanism to the flexible conveying mechanism.

[0032] In the above technical solution, the movement of the goods is achieved by rotating the second roller, which facilitates the linear movement of the goods on the flexible conveying mechanism and the first conveying mechanism.

[0033] In some embodiments of the present application, the conveying device further includes a second driving mechanism, and the second driving mechanism is used to drive some or all of the plurality of second rollers to rotate.

[0050] Example

[0051] At present, people's lives have an increasing demand for logistics. For example, online shopping and mailing require logistics, which requires the logistics industry to invest a lot of manpower in loading and unloading goods every day. Generally, the loading and unloading volume of logistics transport vehicles is large, which makes the labor intensity of the staff very high, and the loading and unloading time is also very long, and the efficiency is low.

[0052] like Figure 1As shown, the embodiment of the present application provides a conveying device 100, which includes a support platform 10 and a flexible conveying mechanism 20. The flexible conveying mechanism 20 includes a flexible conveying member 21 and a transmission wheel 22, the transmission wheel 22 is installed on the support platform 10, the front end of the flexible conveying member 21 is used to connect with the traction device, and the rear end of the flexible conveying member 21 bypasses the transmission wheel 22. The traction device can pull the front end of the flexible conveying member 21 to move forward and backward on the support platform 10. The front end of the flexible conveying member 21 can move under the traction of the traction device, so that the goods placed on the flexible conveying member 21 can follow the flexible conveying member 21 under the traction of the traction device, and the goods can be transported to the loading and unloading space reached by the traction device, reducing the manual handling of the goods. Similarly, if unloading is to be carried out, the traction device pulls the first flexible conveying member 21 to the place to be unloaded, and places the goods on the flexible conveying member 21. The traction device drives one end of the flexible conveying line to move in the unloading direction to achieve unloading, reducing the manual handling of the unloading process. Moreover, the front end movement of the traction device pulling the flexible conveyor 20 can make the working length of the flexible conveyor 20 adapt to the distance change between the cargo storage point and the cargo delivery target location. In addition, the flexible conveyor 21 bypasses the transmission wheel 22, and the flexible conveyor 21 has a bend at the rotating wheel, so that the bend of the flexible conveyor 21 can always dock with other equipment. In the process of the traction device pulling the flexible conveyor 21, the flexible conveyor 21 can be loaded or unloaded, ensuring the continuity of transportation and improving the efficiency of cargo transportation.

[0053] The traction device can pull the front end of the flexible conveyor 21 to move forward and backward on the support platform 10 , which means that the traction device can pull the front end of the flexible conveyor 21 to move along the loading direction A or along the unloading direction B relative to the support platform 10 .

[0054] In this embodiment, a platform 500 is provided on the ground, a receiving cavity 510 is provided on the platform 500 , and the driving wheel 22 is located in the receiving cavity 510 .

[0055] In this embodiment, the flexible conveying member 21 is a chain, and the transmission wheel 22 is a sprocket. The chain and the sprocket cooperate to make the chain or the chain plate move stably relative to the support platform 10, so as to ensure smooth and smooth transportation. At the same time, the sprocket teeth cooperate with the chain to prevent the chain or the chain plate from moving at will. The chain includes a support roller 23, and the chain is supported on the support platform 10 through the support roller 23. The movement of the chain relative to the support platform 10 is achieved by rotating the support roller 23 relative to the support platform 10, which can reduce the friction between the chain and the support platform 10 during the movement process, and can use a smaller traction force to achieve the movement of the chain, while increasing the service life of the chain or the chain plate.

[0056] In this embodiment, the sprocket divides the flexible conveyor 21 into two parts, the part between the traction device and the transmission wheel 22 is located on the support surface of the support platform 10, and the other part is located below the support surface of the support platform 10. When the traction device pulls the chain to move in the loading direction A, the rear end of the chain moves in the unloading direction B, and when the traction device pulls the chain to move in the unloading direction B, the rear end of the chain moves in the loading direction A, that is, the front and rear ends of the chain move in opposite directions, avoiding mutual interference between the two ends of the flexible conveyor 21. The chain part located below the support surface of the support platform 10 is located in the accommodating cavity 510.

[0057] In other embodiments, the front end and rear end of the chain may have other relative movement relationships, for example, the front end of the chain moves in the horizontal direction, and the rear end of the chain moves in the vertical direction, that is, the movement direction of the front end of the chain is perpendicular to the movement direction of the rear end of the chain, or the movement direction of the front end of the chain and the movement direction of the rear end of the chain are arranged at an acute angle or an obtuse angle.

[0058] In order to facilitate the movement of the chain, the conveying device 100 also includes a motor, which is arranged on the supporting platform 10, and the motor is used to drive the transmission wheel 22 to rotate. The motor drives the sprocket to rotate, which is conducive to the movement of the chain. When the traction device and the motor work together, the flexible conveying member 21 moves, which can reduce the power consumption of the traction device. In some embodiments, the sprocket may not be provided with a motor to drive its rotation, and the sprocket is driven to rotate by the horizontal force of the traction device acting on the chain, so that the sprocket assists the chain to move.

[0059] Furthermore, the flexible conveying mechanism 20 further includes a plurality of first rollers 24 arranged at intervals along the extension direction of the flexible conveying member 21, each first roller 24 being rotatably disposed on the flexible conveying member 21, and the rotation of the first roller 24 can move the goods on the first roller 24 relative to the flexible conveying member 21. The arrangement of the first roller 24 enables the goods placed on the first roller 24 to be transported under the action of the first roller 24 when the traction device does not provide traction. If the traction device provides traction, the first roller 24 and the traction device jointly drive the goods to move, which can increase the moving speed of the goods and improve the conveying efficiency.

[0060] In order to facilitate the control of the rotation of the first roller 24, the conveying device 100 further includes a first driving mechanism, which is used to drive some or all of the first rollers 24 to rotate. In this embodiment, the first driving mechanism includes multiple motors, one motor corresponding to driving one first roller 24. In this embodiment, some of the first rollers 24 can be driven by the motor. Generally, the goods need to be supported by several first rollers 24 at the same time. The rotation of some of the first rollers 24 among all the first rollers 24 supporting the goods can realize the movement of the goods relative to the flexible conveying member 21. Therefore, only some of the first rollers 24 need to be provided with motors to realize the movement of the goods relative to the flexible conveying member 21, so as to reduce the use of the first driving mechanism and save costs.

[0061] In other embodiments, the motor of the first driving mechanism can also be set in a one-to-one correspondence with the first roller 24 to ensure that each first roller 24 can be driven to rotate by the motor, which can better ensure the transportation of goods and better adapt to goods of different sizes.

[0062] In some embodiments, the rear end of the chain may also have other arrangements relative to the front end, such as Figure 2 As shown, the rear end of the chain is fixed on the sprocket, and the chain is wound on the sprocket. When the traction device pulls the front end of the chain to move along the loading direction A, the sprocket releases the chain wound on the sprocket. When the traction device drives the chain to move along the unloading direction B, the sprocket reels the chain. When the sprocket is driven by a motor, the sprocket can release the chain by the traction device pulling the chain, or by the motor and the traction device together. The sprocket winding and chain connection can be achieved by the motor driving the sprocket to rotate.

[0063] In other embodiments, the flexible conveyor 21 may be a chain plate, which has a larger width and can accommodate goods with a larger width. The arrangement of the chain plate and the chain may refer to the arrangement of the chain. Accordingly, the chain plate may also include a support roller 23, and the chain plate is supported on the support platform 10 through the support roller 23. The movement of the chain plate relative to the support platform 10 is achieved by rotating the support roller 23 relative to the support platform 10, which can reduce the friction between the chain or chain plate and the support platform 10 during the movement process, and can use a smaller traction force to achieve the movement of the chain plate, while increasing the service life of the chain plate.

[0064] In some embodiments, Figure 3As shown, the flexible conveying member 21 can be a conveyor belt, the driving wheel 22 is a roller shaft, and the conveying device 100 also includes a winding mechanism 30. The winding mechanism 30 is connected to the supporting platform 10 and is located in the accommodating chamber 510. The front end of the conveyor belt is connected to the traction device, and the rear end of the conveyor belt bypasses the driving wheel 22 and is connected to the winding mechanism 30. When the traction end moves along the loading direction A, the winding mechanism 30 winds up the conveyor belt, and when the traction end moves along the unloading direction B, the winding mechanism 30 releases the conveyor belt. Since the conveyor belt is a flexible member, one end of the conveyor belt is pulled by the traction device, and the other end is wound by the winding mechanism 30. When moving in the loading direction A, the main power is provided by the traction device, and when moving in the unloading direction B, the main power is provided by the winding mechanism 30. One end is pulled and the other end is wound, so that the conveyor belt is always in a tensioned state, avoiding the accumulation of the conveyor belt due to pulling and winding, and ensuring smooth transportation. Of course, the winding mechanism 30 can also be used instead Figure 3 The transmission wheel 22 in.

[0065] Furthermore, the conveying device 100 further includes a lifting mechanism 40, the supporting platform 10 is arranged at the upper end of the lifting mechanism 40, the lifting mechanism 40 is located in the accommodating cavity 510, and the lifting mechanism 40 is used to drive the supporting platform 10 to move vertically. The lifting mechanism can drive the supporting platform 10 to move vertically to adapt to cargo platforms of different heights, so that the conveying device 100 has a wider range of applications.

[0066] Among them, Figure 4 , Figure 5 As shown, the lifting mechanism 40 includes a cross structure 41 and a hydraulic cylinder 42, and the conveying equipment 100 also includes a base plate 413. The cross structure 41 includes a first rod 411 and a second rod 412. The first rod 411 and the second rod 412 are cross-hinged, the upper end of the first rod 411 is rotatably connected to the support platform 10, the lower end of the first rod 411 is slidably connected to the base plate 413, the upper end of the second rod 412 is slidably connected to the support platform 10, and the lower end of the second rod 412 is rotatably connected to the base plate 413; the hydraulic cylinder 42 is used to drive the lower end of the first rod 411 to approach the lower end of the second rod 412 and the upper end of the second rod 412 to approach the upper end of the first rod 411, or the hydraulic cylinder 42 is used to drive the upper end of the first rod 411 away from the lower end of the second rod 412 and the upper end of the second rod 412 away from the upper end of the second rod 412. When the lower end of the first rod 411 moves toward the lower end of the second rod 412 and the upper end of the second rod 412 moves toward the upper end of the first rod 411, the support platform 10 rises; when the lower end of the first rod 411 moves away from the lower end of the second rod 412 and the upper end of the second rod 412 moves away from the upper end of the first rod 411, the support platform 10 descends.

[0067] In this embodiment, the lifting mechanism 40 includes two cross structures 41 arranged at intervals along the conveying direction of the vertical flexible conveying mechanism 20. The first rods 411 of the two cross structures 41 are connected by a cross bar, and the telescopic end of the hydraulic cylinder 42 is connected to the cross bar, and the lifting platform is lifted and lowered by driving the cross bar to move.

[0068] In some embodiments, only one cross structure 41 may be provided, and hydraulic pressure acts on the first rod 411 or the second rod 412 .

[0069] In other embodiments, the lifting mechanism 40 may also only include a vertically driven linear drive mechanism such as a cylinder, a hydraulic cylinder, a linear motor, etc.

[0070] Furthermore, if Figure 6 As shown, the conveying device 100 also includes a fixed conveying mechanism 50, and the front end of the fixed conveying mechanism 50 is used to dock with the turning part of the flexible conveying mechanism 20. The front end of the fixed conveying mechanism 50 docks with the turning part of the flexible conveying mechanism 20, so that the fixed conveying mechanism 50 can continuously transport goods to the flexible conveying mechanism 20 or the goods on the flexible conveying mechanism 20 can be continuously transported to the fixed conveying mechanism 50, thereby improving the transportation efficiency. In addition, the traction device pulls the front end of the flexible conveying member 20 to move so that the working length of the flexible conveying member 20 can adapt to the distance change between the fixed conveying mechanism 50 and the target position of the goods to be transported.

[0071] In this embodiment, the fixed conveying mechanism 50 includes a first conveying mechanism 51 and a second conveying mechanism 52. The front end of the first conveying mechanism 51 is used to dock with the turning point of the flexible conveying mechanism 20, and the rear end of the first conveying mechanism 51 is used to dock with the second conveying mechanism 52; the second conveying mechanism 52 includes a transmission mechanism 521 and an information collection device 522 arranged on the transmission mechanism 521. The transmission mechanism 521 is used to transport the goods to the information collection device 522 and transport the goods with information collection to the first conveying mechanism 51. The information collection device 522 is convenient for collecting information such as the shape and size of the goods and planning the loading space. At the same time, the flexible conveying mechanism 20 and the second conveying mechanism 52 are docked through the first conveying mechanism 51, which can extend the length of the entire conveying equipment 100 and facilitate the transportation of more goods at one time. The transmission mechanism 521 can adopt a conveying method in the form of a conveyor belt, a conveyor chain, etc.

[0072] The first conveying mechanism 51 includes a frame 511 and a plurality of second rollers 512 arranged at intervals on the frame 511. The frame 511 of the first conveying mechanism 51 can be arranged on the platform 500, and each second roller 512 can be rotatably arranged on the frame 511; the second rollers 512 can be rotated to convey the goods on the first conveying mechanism 51 to the flexible conveying mechanism 20. The movement of goods by the rotation of the second rollers 512 facilitates the linear movement of goods between the flexible conveying mechanism 20 and the first conveying mechanism 51.

[0073] The conveying device 100 also includes a second driving mechanism, which is used to drive some or all of the second rollers 512 in the plurality of second rollers 512 to rotate. The second driving mechanism includes a plurality of motors, one motor corresponding to driving one second roller 512. Generally, the goods need to be supported by several second rollers 512 at the same time. The rotation of some of the second rollers 512 in all the second rollers 512 supporting the goods can realize the movement of the goods relative to the flexible conveying member 21. Therefore, in this embodiment, some of the second rollers 512 are equipped with motors to drive them to rotate, so as to reduce the use of the second driving mechanism and save costs. However, in other embodiments, the second rollers 512 and the motors of the second driving mechanism can also be set one-to-one, that is, each second roller 512 has a motor to drive it to rotate, so that the first conveying mechanism 51 can transport the goods more stably and smoothly.

[0074] In some embodiments, the fixed conveying mechanism 50 may include only the first conveying mechanism 51 or only the second conveying mechanism 52. When the fixed conveying mechanism 50 includes only the first conveying mechanism 51, the front end of the first conveying mechanism 51 is docked with the turning point of the flexible conveying mechanism 20. When the fixed conveying mechanism 50 includes only the second conveying mechanism 52, the front end of the transmission mechanism 521 of the second conveying mechanism 52 is docked with the turning point of the flexible conveying mechanism 20.

[0075] Since the flexible conveying mechanism 20 can adjust the vertical height under the action of the jacking mechanism 40, in order to adapt to the height change of the flexible conveying mechanism 20 and to ensure that the goods can be transported between the flexible conveying mechanism 20, the first conveying mechanism 51 and the second conveying mechanism 52, the first conveying mechanism 51 and the second conveying mechanism 52 can also be provided with an adjustment mechanism that can vertically adjust the vertical height of the first conveying mechanism 51 and the second conveying mechanism 52, and the structure of the adjustment mechanism can be set with reference to the jacking mechanism 40.

[0076] like Figure 7As shown, when loading into the carriage 210 of the truck 200, the traction device 400 first pulls the front end of the flexible conveying member 20 to move so that the working length of the flexible conveying member 20 can adapt to the distance change between the fixed conveying mechanism 50 (cargo storage point) and the cargo delivery target position (different loading positions in the carriage 210). Of course, the flexible conveying member 20 can also be first pulled to the cargo delivery target position in the carriage 210 by the traction device 400, so that a complete conveying relationship can be formed between the cargo delivery target position, the flexible conveying mechanism 20 and the fixed conveying mechanism 50, and then the first driving mechanism drives the first roller 24 to transport the cargo from the fixed conveying mechanism 50 to the cargo delivery target position along the loading direction A. As the cargo in the carriage 210 increases, the length of the chain above the support platform 10 becomes shorter and shorter, and the length of the chain below the support platform 10 becomes longer and longer.

[0077] In some embodiments, the cargo 300 may be first moved from the rear end of the second conveying mechanism 52 to the transmission mechanism 521, and pass through the information collection device 522 and the first conveying mechanism 51 in sequence, and finally moved to the flexible conveying mechanism 20. The traction device 400 pulls the flexible conveying member 21 to move along the loading direction A. In order to improve the conveying efficiency, the first roller 24 is driven to rotate by the first driving mechanism at the same time, so that the traction device 400 pulls the flexible conveying member 21, the first driving mechanism drives the first roller 24 to rotate, and the motor drives the transmission wheel 22 in the forward direction to rotate. The flexible conveying member 21 and the first roller 24 jointly convey the cargo 300 to the carriage 210 of the truck 200, and at the same time, the portion of the flexible conveying member 21 located below the supporting surface of the support platform 10 gradually becomes shorter.

[0078] like Figure 8 As shown, when unloading from the carriage 210 of the truck 200, the traction device 400 first pulls the flexible conveying member 20 to the position to be unloaded in the carriage 210 through the traction device 400, so that a complete conveying relationship can be formed between the position to be unloaded, the flexible conveying mechanism 20 and the fixed conveying mechanism 50, and then the first driving mechanism drives the first roller 24 to convey the goods from the fixed conveying mechanism 50 to the fixed conveying mechanism 50 or other equipment along the unloading direction B. As the number of goods in the carriage 210 decreases, the length of the chain above the support platform 10 becomes longer and longer, and the length of the chain below the support platform 10 becomes shorter and shorter.

[0079] In some embodiments, the traction device 300 may also drive the flexible conveying member 21 to move along the unloading direction B. In order to improve the conveying efficiency, the first roller 24 is driven to rotate by the first driving mechanism at the same time, so that the traction device 400 pulls the flexible conveying member 21 and the first driving mechanism drives the first roller 24 to rotate. The flexible conveying member 21 and the first roller 24 jointly transport the goods 300 in the carriage 210 of the truck 200, and at the same time, the part of the flexible conveying member 21 located below the supporting surface of the support platform 10 gradually becomes longer.

[0080] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
