Description

Technical Field

[0001] The present invention relates to the technical field of railway transportation, and in particular to a locking device and a vehicle device having the same. Background Art

[0002] Container transportation is the main mode of modern logistics and multimodal transport, and has been widely adopted by countries around the world. At present, container rail transport generally uses container flat cars or open cars. When loading containers on container flat cars, special locking devices are required to fix the containers. The locking devices are generally distributed at the ends and the middle of the flat car body. The end locks are generally fixed; the middle locks are mostly mobile, which are divided into push-pull translation type and push-pull flip type. The lock head can be manually translated or flipped to achieve the conversion between working position and non-working position.

[0003] In the related art, when the container is assembled with the vehicle body, the container is locked by the upper hook of the locking device. During transportation, the container may easily break away from the upper hook due to bumps and shaking, which may easily cause the locking device to fail, thereby separating the container from the vehicle body. Summary of the invention

[0004] The main purpose of the present invention is to provide a locking device and a vehicle device having the same, so as to solve the problem in the related art that the locking device is easy to fail and thus the container is easy to separate from the vehicle body.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a locking device is provided, comprising: a base; a clamping assembly, arranged on the base, the clamping assembly comprising a plurality of clamping members, each of which is hingedly connected to the base, each of which is swingably arranged, and the plurality of clamping members are arranged at intervals along a preset circumferential direction, and each of the clamping members has an inward clamping state and an outward swinging avoidance state; a plurality of clamping recesses, each of which is provided with a clamping recess, and when each clamping member is in the outward swinging avoidance state, the clamped member can move downward from the space between the plurality of clamping members to between the plurality of clamping recesses, and when the clamped member moves downward, each clamping member can be driven to switch from the outward swinging avoidance state to the inward clamping state to clamp the clamped member.

[0006] Furthermore, each clamping recess has a bearing surface and a clamping surface, the bearing surface is located at the bottom of the clamping recess, and the clamping surface is located at the top surface of the clamping recess. When the clamping assembly switches from an outward swing avoidance state to an inward retracted clamping state, the angle between the bearing surface and the horizontal plane gradually decreases, and the angle between the clamping surface and the horizontal plane gradually decreases.

[0007] Furthermore, an end portion of the clamping surface away from the bearing surface is located in a space defined by the bearing surface.

[0008] Furthermore, the clamping recess also has a connecting surface, and the connecting surface is located between the bearing surface and the clamping surface. When the clamping assembly is in the clamping state, the bearing surface is arranged horizontally.

[0009] Furthermore, the angle between the clamping surface and the bearing surface is between 30° and 60°.

[0010] Furthermore, the locking device further comprises a first recess, which is located at the intersection of the connecting surface and the clamping surface, and / or the locking device further comprises a second recess, which is located at the intersection of the connecting surface and the bearing surface.

[0011] Furthermore, the clamping part includes a connecting part and a clamping part, the connecting part is hingedly connected to the base, the clamping part is connected to the connecting part, the clamping part includes a clamping body and an outwardly protruding stopper, the clamping body stops the clamped part in a first direction, the outwardly protruding stopper stops the clamped part in a second direction, and the first direction and the second direction are arranged vertically.

[0012] Further, in a projection of the clamping member on a preset surface parallel to an axis of a preset circle, a surface of the clamping member on a side away from the clamping recess is in an arc shape.

[0013] Furthermore, the locking device also includes a connecting seat, which is arranged on the base and is hingedly connected to the clamping member.

[0014] Furthermore, the base includes a shell, an elastic component and a top plate. The elastic component is arranged in the shell. An opening is arranged on the top of the shell. The top plate is located in the opening and connected to the elastic component.

[0015] Furthermore, a positioning structure is provided inside the shell, and the elastic component is positioned and matched with the positioning structure.

[0016] Furthermore, the elastic component includes a first mounting tube, a second mounting tube and an elastic member, the first mounting tube and the second mounting tube are nested, the elastic member is arranged between the first mounting tube and the second mounting tube, the second mounting tube is connected to the elastic member, and there is a gap between the top wall of the second mounting tube and the first mounting tube.

[0017] Further, the positioning structure includes a positioning ring arranged on the bottom wall of the shell, and the first mounting tube is inserted into the positioning ring.

[0018] According to another aspect of the present invention, a vehicle device is provided, comprising a vehicle body, a locking device arranged on the vehicle body, and a container detachably mounted on the vehicle body, wherein the locking device is the above-mentioned locking device.

[0019] According to the technical solution of the present invention, a clamping assembly is arranged on a base, and the clamping assembly includes a plurality of clamping members, each of which is hingedly connected to the base, and each of which can be swingably arranged. The plurality of clamping members are arranged at intervals along a preset circumferential direction. A clamping recess is arranged on each clamping member, and when each clamping member is in an outward swing avoidance state, the clamped member can move downward from the space between the plurality of clamping members to between the plurality of clamping recesses. When the clamped member moves downward, each clamping member can be driven to switch from the outward swing avoidance state to the recovery clamping state and clamp the clamped member. Through the above arrangement, when the clamped part enters the clamping assembly from the top of the clamping assembly and moves downward, the clamped part enters into multiple clamping recesses and the clamped part can press the bottom wall of the clamping recess, thus forming a self-locking structure and being able to lock the clamped part. When the clamped part slides or tilts, the force applied by the clamped part to the clamping part is divided into a downward direction and a direction toward the side wall of the clamping recess, that is, the clamped part has a component force applied downward in any state, thus ensuring that multiple clamps will not be opened. When the clamped part needs to be moved out, the clamped part is moved upward, at which time the side wall of the clamped part pushes the side wall of the clamping recess, and the bottom wall of the clamping recess is not subjected to force, thus enabling multiple clamps to switch from the retracted clamping state to the outward swing avoidance position. Therefore, the technical solution of the present application effectively solves the problem in the related art that the locking device is prone to failure, which leads to the easy separation of the container and the vehicle body.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0042] like Figures 1 to 3 As shown, in this embodiment, the locking device includes: a base 10, a clamping assembly 20 and a plurality of clamping recesses 30. The clamping assembly 20 is arranged on the base 10, and the clamping assembly 20 includes a plurality of clamping members 21, each of which is hingedly connected to the base 10, each of which is swingably arranged, and a plurality of clamping members 21 are arranged at intervals along a preset circumferential direction, and each of which has an inward clamping state and an outward swing avoidance state. A clamping recess 30 is arranged on each clamping member 21, and when each clamping member 21 is in the outward swing avoidance state, the clamped member 1 can move downward from the space between the plurality of clamping members 21 to between the plurality of clamping recesses 30, and when the clamped member 1 moves downward, each clamping member 21 can be driven to switch from the outward swing avoidance state to the inward clamping state to clamp the clamped member 1.

[0043] The technical solution of this embodiment is applied, and the clamping assembly 20 is arranged on the base 10. The clamping assembly 20 includes a plurality of clamping members 21, each of which is hingedly connected to the base 10, and each of which can be swingably arranged. The plurality of clamping members 21 are arranged at intervals along a preset circumferential direction. A clamping recess 30 is arranged on each clamping member 21. When each clamping member 21 is in an outward swing avoidance state, the clamped member 1 can move downward from the space between the plurality of clamping members 21 to between the plurality of clamping recesses 30. When the clamped member 1 moves downward, each clamping member 21 can be driven to switch from the outward swing avoidance state to the recovery clamping state and clamp the clamped member 1. Through the above arrangement, when the clamped part 1 enters the clamping assembly 20 from the top of the clamping assembly 20 and moves downward, the clamped part 1 enters into the multiple clamping recesses 30 and the clamped part 1 can press the bottom wall of the clamping recess 30, thus forming a self-locking structure and being able to lock the clamped part 1. When the clamped part 1 slides or tilts, the force applied by the clamped part 1 to the clamping part is divided into the downward direction and the direction toward the side wall of the clamping recess 30, that is, the clamped part 1 has a component force applied downward in any state, thus ensuring that the multiple clamping parts 21 will not be opened. When the clamped part 1 needs to be moved out, the clamped part 1 is moved upward, at which time the side wall of the clamped part 1 pushes the side wall of the clamping recess 30, and the bottom wall of the clamping recess 30 is not subjected to force, thus enabling the multiple clamping parts 21 to switch from the inward clamping state to the outward swing avoidance position. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the locking device is prone to failure, which leads to the easy separation of the container and the vehicle body.

[0044] Each clamping recess 30 has a bearing surface 31 and a clamping surface 32. The bearing surface 31 is located at the bottom of the clamping recess 30, and the clamping surface 32 is located at the top surface of the clamping recess 30. When the clamping assembly 20 switches from the outward swing avoidance state to the inward clamping state, the angle between the bearing surface 31 and the horizontal plane gradually decreases, and the angle between the clamping surface 32 and the horizontal plane gradually decreases. The above-mentioned bearing surface 31 can effectively support the clamped part 1, and the clamping surface 32 can limit the top or side of the clamped part 1, thereby making the position of the clamped part 1 more stable. Specifically, when the clamping assembly 20 switches from the inward clamping state to the outward swing avoidance state, the distance between the two corresponding clamping surfaces 32 increases, thereby making it easier to take out the clamped part 1.

[0045] Specifically, the above design can ensure the stability of the clamped member 1 when entering and exiting the locking device, reduce friction and impact caused by angle changes, and is suitable for occasions with high stability requirements, such as container fixing during high-speed transportation.

[0046] like Figure 1 , Figure 2 as well as Figures 9 to 12 As shown, in this embodiment, the end of the clamping surface 32 away from the bearing surface 31 is located in the space defined by the bearing surface 31. The above arrangement makes the area of ​​the bearing surface 31 larger, which not only improves the clamping stability, but also makes it easier to remove the clamped part 1.

[0047] Specifically, the above design can further enhance the clamping force of the locking device on the clamped part 1, preventing the clamped part 1 from being displaced when subjected to external force, and is particularly suitable for environments that may encounter bumps and vibrations during transportation. In actual use, this design enables the locking device to maintain a firm lock on the container even under extremely harsh transportation conditions, effectively preventing damage to the goods during transportation.

[0048] like Figure 1 , Figure 2 as well as Figures 9 to 12 As shown, in this embodiment, the clamping recess 30 further has a connecting surface 33, and the connecting surface 33 is located between the bearing surface 31 and the clamping surface 32. When the clamping assembly 20 is in the clamping state, the bearing surface 31 is arranged horizontally. The above arrangement can make the support more stable.

[0049] Specifically, the horizontally arranged bearing surface 31 can provide a stable supporting platform to ensure the balance of the clamped component 1 in a locked state, and is suitable for fixing objects that need to remain in a stable state for a long time.

[0050] like Figure 1 , Figure 2 as well as Figures 9 to 12 As shown, in this embodiment, the angle between the clamping surface 32 and the bearing surface 31 is between 30° and 60°. The above angle setting can ensure the clamping effect and make it easier to remove the clamped part.

[0051] The selection of the above-mentioned angle range not only ensures that the locking device firmly clamps the clamped part 1, but also avoids the difficulty of loading and unloading caused by too large an angle. It is suitable for clamped parts of various sizes and shapes, and improves the versatility of the locking device.

[0052] like Figure 1 , Figure 2 as well as Figures 9 to 12As shown, in this embodiment, the locking device further includes a first recess 41, which is located at the intersection of the connecting surface 33 and the clamping surface 32, and the locking device further includes a second recess 42, which is located at the intersection of the connecting surface 33 and the bearing surface 31. The arrangement of the first recess 41 and the second recess 42 can effectively reduce stress concentration, that is, the first recess 41 can prevent tearing between the connecting surface 33 and the clamping surface 32, and the second recess 42 can prevent tearing between the connecting surface 33 and the bearing surface 31.

[0053] like Figure 1 , Figure 2 as well as Figures 8 to 11 As shown, in this embodiment, the clamping member 21 includes a connecting portion 211 and a clamping portion 212, the connecting portion 211 is hingedly connected to the base 10, the clamping portion 212 is connected to the connecting portion 211, the clamping portion 212 includes a clamping body 2121 and an outer convex stopper 2122, the clamping body 2121 stops the clamped member 1 in the first direction, the outer convex stopper 2122 stops the clamped member 1 in the second direction, and the first direction and the second direction are arranged perpendicularly. The above arrangement makes the overall structure relatively simple and can effectively limit the clamped member 1.

[0054] Specifically, the above design can effectively fix the clamped part 1 from multiple directions, improve the reliability of locking, and is particularly suitable for scenarios that require all-round stable fixation, such as equipment fixation on aerial work platforms. In the application of aerial work platforms, this locking device can ensure that the equipment can be firmly locked at any angle, greatly improving the safety and stability of aerial work and reducing the risk of aerial work.

[0055] Specifically, Fig.11As shown, the outer wall of the clamping member 21 is composed of a first arc, a second arc, a third arc, a fourth arc, a fifth arc and a sixth arc. From the end of the clamping surface 32 away from the bearing surface to the end of the bearing surface 31 away from the clamping body 2121, the first arc, the second arc, the third arc, the fourth arc, the fifth arc and the sixth arc are connected in sequence and are tangent to each other. The radius of the first arc is smaller than the radius of the second arc, the radius of the third arc is larger than the radius of the first arc and smaller than the radius of the second arc, the radius of the fourth arc is larger than the radius of the second arc, the radius of the fifth arc is equal to the radius of the third arc, the radius of the sixth arc is equal to the radius of the second arc, the center of the circle where the first arc is located is point a, the center of the circle where the second arc is located is point b, the center of the circle where the third arc is located is point c, the center of the circle where the fourth arc is located is point d, the center of the circle where the fifth arc is located is point e, and the center of the circle where the sixth arc is located is point b, that is, the center of the circle where the second arc is located coincides with the center of the circle where the sixth arc is located. In the vertical direction, point a, point c, point d, point b and point e are arranged in sequence, point a and point b are both on the same vertical line, point c and point e are both on the same vertical line, and point d is located outside the clamp.

[0056] like Figures 1 to 3 As shown, in this embodiment, the locking device further comprises a connecting seat 50, which is arranged on the base 10 and is hingedly connected to the clamping member 21. The arrangement of the connecting seat 50 can make the swing of the clamping member 21 more stable.

[0057] It should be noted that the addition of the connection seat 50 makes the installation and removal of the locking device more convenient, improves the maintenance efficiency of the equipment, and is suitable for scenes where regular equipment maintenance and overhaul are required, such as the fixing of containers on railway transport vehicles. In the railway transportation environment, this convenient installation and disassembly design can significantly reduce the time for equipment maintenance and overhaul, improve the utilization efficiency of railway transport vehicles, reduce operating costs, and also facilitate the rapid replacement of the locking device when necessary to ensure safety during transportation.

[0058] like Figures 1 to 5 as well as Figure 7 and Figure 8 As shown, in this embodiment, the base 10 includes a housing 11, an elastic component 12 and a top plate 13. The elastic component 12 is arranged in the housing 11. An opening 111 is arranged on the top of the housing 11. The top plate 13 is located in the opening 111 and connected to the elastic component 12. The arrangement of the elastic component 12 can provide a buffer for the clamping component 20, so as to prevent the clamping component 20 from being damaged by the impact of the clamping member 1 on the clamping component 20.

[0059] Specifically, the setting of the elastic component 12 enables the locking device to have a certain buffering effect when subjected to external force impact, reducing damage to the clamped part 1, and is suitable for environments that may encounter strong impacts during transportation, such as container fixing in ocean transportation. In the environment of ocean transportation, this elastic component design with a buffering effect can effectively absorb waves and other external impact forces, reduce damage to the container during transportation, protect the safety of the goods, and improve the reliability and economy of ocean transportation.

[0060] It should be noted that there is a gap between the top plate 13 and the opening 111, and the top plate 13 can slide in the opening 111. A positioning plate is provided on the periphery of the opening 111, and the positioning plate has positioning and guiding functions. A water collecting trough is provided on the bottom plate of the outer shell 11, and a drainage hole is provided on the side plate of the outer shell 11. The drainage hole is connected to the water collecting trough. The depth and width of the water collecting trough should not be too large, and the size of the drainage hole can be suitable for the water collecting trough, so as to realize the water collecting and drainage functions. The form of the water collecting trough is not limited, and the water collecting trough is provided near the two ends of the side plate of the positioning structure 61, with at least one on each side.

[0061] like Figures 1 to 5 As shown, in this embodiment, a positioning structure 61 is disposed inside the housing 11, and the elastic component 12 is positioned and matched with the positioning structure 61. The positioning structure 61 can effectively limit the position of the elastic component 12, thereby preventing the elastic component 12 from being deflected.

[0062] The addition of the positioning structure 61 can ensure the stable position of the elastic component 12 inside the locking device, avoiding locking failure caused by displacement of the elastic component 12, and is suitable for fixing items that need to remain stable for a long time.

[0063] like Figures 1 to 5 as well as Figure 7 As shown, in this embodiment, the elastic component 12 includes a first mounting cylinder 121, a second mounting cylinder 122 and an elastic member 123. The first mounting cylinder 121 and the second mounting cylinder 122 are arranged in a nested manner, the elastic member 123 is arranged between the first mounting cylinder 121 and the second mounting cylinder 122, the second mounting cylinder 122 is connected to the elastic member 123, and there is a gap between the top wall of the second mounting cylinder 122 and the first mounting cylinder 121. Since there is a gap between the second mounting cylinder 122 and the first mounting cylinder 121, the second mounting cylinder 122 can move downward, thereby realizing elastic buffering, and at the same time, the first mounting cylinder 121 and the second mounting cylinder 122 are arranged in a nested manner, so that the relative movement of the first mounting cylinder 121 and the second mounting cylinder 122 is relatively stable.

[0064] This structural design can ensure the stability and reliability of the elastic member 123 during operation, and is suitable for scenarios that need to withstand frequent external force impacts.

[0065] like Figures 1 to 5 as well as Figure 7 As shown, in this embodiment, the positioning structure 61 includes a positioning ring 611 arranged on the bottom wall of the housing 11, and the first mounting tube 121 is inserted into the positioning ring 611. The above arrangement can make the elastic buffering effect better, and the elastic component 12 can be effectively positioned under the action of the positioning ring 611.

[0066] In another embodiment, Figure 6 As shown, the first installation barrel 121 includes a first barrel section 1211 and a second barrel section 1212, the diameter of the first barrel section 1211 is smaller than the diameter of the second barrel section 1212, the second barrel section 1212 is located between the first barrel section 1211 and the second installation barrel 122, the positioning structure 61 includes a positioning ring 611 arranged on the bottom wall of the housing 11, and the first barrel section 1211 is inserted into the positioning ring 611. Specifically, the elastic member 123 is a rubber block, the rubber block includes a first column section and a second column section, the first column section is located in the first barrel section 1211, the second column section is located in the second barrel section 1212, and there is a gap between the rubber block and the side wall of the first installation barrel 121.

[0067] This segmented design not only improves the installation accuracy of the elastic component 12 , but also facilitates the replacement and maintenance of the elastic component 12 .

[0068] In an embodiment not shown in the figures, the elastic member may be a spring, an elastic member combining a spring and a rubber body, a gas spring, a hydraulic spring, etc.

[0069] It should be noted that the positioning ring 611 is a whole ring. In an embodiment not shown in the figure, the positioning ring 611 includes a plurality of arc segments arranged at intervals.

[0070] Specifically, in this embodiment, in order to ensure that the clamped member 1 is limited in position, the number of the clamping members 21 is greater than or equal to 3. When there are three clamping members 21, the three clamping members 21 are arranged at intervals.

[0071] In other embodiments, Fig.13 and Fig.14 As shown, in the projection of the clamping member 21 on the preset surface parallel to the axis of the preset circumference, the surface of the clamping member 21 away from the clamping recess 30 is in an arc shape. The above-mentioned configuration ensures the stability of clamping, that is, the clamping member 21 has a certain length in the circumferential direction of the preset circumference, so that the clamping assembly 20 can ensure the stability of clamping by only including two clamping members 21.

[0072] According to another aspect of the present application, a vehicle device is provided, such as Fig.15 and Fig.16As shown, the vehicle device of this embodiment includes a vehicle body 2, a locking device arranged on the vehicle body 2, and a container 3 detachably mounted on the vehicle body 2, and the locking device is the above-mentioned locking device. The locking device of this vehicle device can quickly and safely lock and release the container 3, effectively improving the safety and operational convenience during transportation. It is particularly suitable for logistics vehicles that need to frequently load and unload containers 3, such as container trucks, railway transport vehicles, etc., and can significantly improve loading and unloading efficiency and reduce logistics costs. In practical applications, the vehicle device of this locking device is not only suitable for conventional logistics transportation, but also can be used in special scenarios such as emergency rescue. Its efficient and stable locking performance can ensure transportation safety under complex conditions and improve the versatility and adaptability of the vehicle device.

[0073] Specifically, the technical solution of this embodiment provides a stable, long-lasting, soft-contact, and durable container locking device. During the shipping process, the container 3 needs to be locked with the vehicle body 2 before it can be transported. The technical solution of this embodiment realizes soft contact between the container 3 and the vehicle body 2, avoids hard collision and hard connection, reduces the damage and destruction of the lock head and lock seat of the container 3 and the vehicle body 2, extends the service life, reduces the frequency of maintenance and replacement of the container locking device, and reduces maintenance costs. On the other hand, it also ensures the safety of the container in transportation and vehicle driving, and provides protection for the safety of life and property.

[0074] The locking device of this embodiment is preferably a railway container flat car, but the locking device can exist independently of the flat car and can be used as long as it is needed to transport the container. When the locking device is not loaded with container 3, the flip clamping assembly 20 is in an outwardly opened state under the elastic action of the elastic assembly 12, and the opening angle is 30°. When the container 3 is shipped, the lock of the container 3 will fall downward into the flip clamping assembly 20, and the clamping surface 32 of the flip clamping assembly 20 has a guiding and centering function. As the lock falls in, it will slowly be clamped in the center. As the container 3 continues to fall, the flip clamping assembly 20 transmits pressure to the top plate 13, and the top plate 13 presses on the elastic assembly 12. The second mounting tube 122 of the elastic assembly 12 will compress the elastic member 123 until the container 3 falls on the bottom frame of the vehicle body 2, thereby locking the container 3, thereby buffering the container 3 and the bottom frame of the vehicle body 2, avoiding hard collision, avoiding hard landing of the container 3, avoiding or reducing damage to the lock at the bottom of the container 3 and the lock seat on the vehicle body 2, which can extend the service life and reduce maintenance costs. In addition, it also ensures the safety of the container during transportation and vehicle driving.

[0075] The locking device and its application in the vehicle device realizes efficient and stable clamping of the clamped part 1 through the automatic switching of the clamping assembly 20, reduces manual operation, and improves loading and unloading efficiency. In particular, in the vehicle device, the locking device can quickly and safely lock and release the container 3, effectively improving the safety and convenience of operation during transportation. The wide application of this locking device can not only significantly improve the loading and unloading efficiency of the logistics industry and reduce labor costs, but also improve the safety of cargo transportation and reduce cargo losses during transportation, with significant economic and social benefits. In practical applications, this locking device can also be customized according to specific needs, such as adjusting the number and angle of the clamping members 21 and the strength of the elastic component 12, etc., to adapt to different types of clamped parts and different use environments, further expanding its application range and improving its competitiveness in the market. For example, for the transportation of oversized goods, by increasing the number and strength of the clamping members 21 and adjusting the parameters of the elastic component 12, a greater clamping force and a more stable locking effect can be provided to meet the needs of special cargo transportation and improve the transportation industry's adaptability and processing capabilities for various goods.

[0076] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0077] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0078] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
