Description

Technical Field

[0001] This application relates to the field of transportation, and in particular to a suitcase. Background Technology

[0002] Currently, the core function of suitcases on the market focuses on storage. However, when users need to rest temporarily while traveling or commuting, the suitcase itself cannot provide effective support. Users often have to find public seating or sit on the ground, making temporary rest inconvenient. To improve this, some suitcases have attempted to add auxiliary support components. However, these components are usually inextricably linked to the suitcase body, not only increasing the overall size and weight of the suitcase, making it inconvenient to carry and store, but also taking up extra space when the support components are not needed, affecting the normal pushing and storing of the suitcase. Utility Model Content

[0003] Therefore, it is necessary to provide a suitcase that can meet users' needs for temporary rest while improving the suitcase's portability and storage capacity.

[0004] This utility model provides a suitcase, comprising:

[0005] Box;

[0006] A seat is detachably mounted on the top of the housing. The seat is rotatable relative to the housing about a preset axis and has an open state and a closed state. In the open state, the seat and the top of the housing form an accommodating space. In the closed state, the seat is in contact with the top of the housing. A rotating assembly includes a rotating shaft extending along the preset axis and a rotating member detachably mounted on the rotating shaft. The rotating member is rotatable about the rotating shaft. One of the rotating shaft and the rotating member is mounted on the housing, and the other is mounted on the seat.

[0007] This design, with its detachable connection between the seat and the suitcase, allows users to choose to install or remove the seat as needed. Removing the seat reduces the overall size and weight of the suitcase, making it easier to carry either the suitcase or the seat separately and improving adaptability to different scenarios. Secondly, when open, the seat provides a resting space for users, meeting their needs for temporary rest. Furthermore, when closed, the close fit between the seat and the top of the suitcase ensures the overall neatness of the suitcase, preventing the seat from protruding and taking up space, and not affecting the normal pushing and storage of the suitcase. At the same time, the rotating component is detachably located on the rotating shaft, forming a linkage with the detachable connection between the seat and the suitcase. Users only need to separate the rotating component from the rotating shaft to complete the removal of the seat, a simple operation that requires no complicated tools.

[0008] In one embodiment, the seat includes a backrest and baffles disposed on both sides of the backrest. In the closed state, the two baffles are in contact with the two sides of the housing, and the backrest is in contact with the top surface of the housing.

[0009] With this design, the backrest structure provides back support for the user when sitting. When closed, the side panels fit snugly against the sides of the box, further filling the gap between the seat and the box. When open, the panels can cover the sides of the storage space, preventing the user from falling off the seat and items from falling out of the storage space.

[0010] In one embodiment, the rotating shaft is disposed at the top of the housing, the rotating component is disposed at the bottom of the seat and has a rotating hole extending along the preset axis, the rotating shaft can extend into / out of the rotating hole and can reciprocate within the rotating hole.

[0011] With this configuration, the movement of the rotating shaft into or out of the rotating hole directly enables the disassembly of the rotating component, thereby completing the disassembly of the seat and the housing.

[0012] In one embodiment, the suitcase further includes a disassembly assembly disposed on the top of the suitcase body and connected to the rotating shaft, the disassembly assembly being capable of driving the rotating shaft to extend into / disengage from the rotating hole.

[0013] This setup, by introducing disassembly components, enables mechanized control of the seat disassembly process.

[0014] In one embodiment, the disassembly assembly includes a pressing member capable of reciprocating along the preset axis, and a rotating shaft connected to the pressing member and capable of moving with the pressing member to extend into / disengage from the rotating hole.

[0015] This design allows for easy control of the rotating shaft by simply pressing the button, lowering the operational threshold and improving the efficiency of installing or removing the seat.

[0016] In one embodiment, the disassembly assembly further includes a spring disposed between the housing and the pressing member. When the pressing member moves toward a side away from the rotating member, the spring is compressed and applies a force to the pressing member to move toward the rotating member.

[0017] With this configuration, the elastic force of the spring can automatically reset the pressing part. After the user presses the pressing part to disengage the rotating shaft from the rotating hole and removes the seat, the spring can push the pressing part to reset.

[0018] In one embodiment, the disassembly assembly further includes a limiting component, wherein when the pressing member moves toward the side away from the rotating member until the rotating shaft disengages from the rotating hole, the pressing member cooperates with the limiting component to limit the movement.

[0019] With this design, the limiting component can fix the pressing part in the current position after the rotating shaft disengages from the rotating hole, so that the user can remove or install the seat without having to keep pressing the pressing part.

[0020] In one embodiment, the limiting component includes a return spring, an abutment, and a latching member. The latching member is disposed on the top of the housing and located on the side of the pressing member away from the rotating member. The abutment is disposed between the pressing member and the latching member and is capable of reciprocating along the preset axis. The return spring is disposed between the abutment and the housing.

[0021] When the pressing member moves toward the side away from the rotating member until the rotating shaft disengages from the rotating hole, the abutting member is pushed by the pressing member to engage with the locking member;

[0022] As the pressing member continues to move toward the side away from the rotating member, the return spring is compressed and can apply a force to the abutment member, causing it to move toward the rotating member and separate from the locking member.

[0023] With this configuration, the "engagement-disengagement" process of the limiting component is achieved through the step-by-step movement of the pressing part. The user only needs to press again to complete the operations of "disengaging the drive shaft", "engaging the abutment part", and "disengaging and resetting the abutment part", without the need for additional operation of the limiting component, thus simplifying the operation process. The reset spring can automatically push the abutment part to separate when the pressing part continues to move, ensuring that the limiting state can be flexibly released.

[0024] In one embodiment, the suitcase further includes a cover covering the outside of the rotating assembly and the disassembly assembly, with at least a portion of the pressing member extending out of the cover.

[0025] With this design, at least part of the pressing component extends out of the cover, ensuring that the user can operate the pressing component normally and that the disassembled components will not be unusable due to the cover, thus balancing protection and ease of operation.

[0026] In one embodiment, the top of the suitcase is provided with a first abutment at the end away from the suitcase body, and the seat is provided with a second abutment at the end near the rotating assembly. In the open state, the first abutment and the second abutment abut against each other.

[0027] With this design, the engagement of the first and second abutting parts can set a fixed limit position for the open state of the seat, preventing the seat from rotating excessively away from the body.

[0028] In one embodiment, the suitcase further includes a pull rod and a pull cord. The pull rod is telescopically disposed on the side of the suitcase body away from the rotating assembly. In the open state, when the pull rod extends out of the top of the suitcase body, the two ends of the pull cord are detachably connected to the pull rod and the seat, respectively. And / or, the suitcase body further includes a first latching part, and the seat further includes a second latching part. In the closed state, the first latching part and the second latching part engage.

[0029] This design, with its retractable pull rod, allows users to adjust the extension length of the pull rod according to the height of the seat when it is open, ensuring that the pull rope remains taut. The detachable connections at both ends of the pull rope make it easy for users to remove the rope when not needed, preventing it from getting tangled in other parts. When the seat is open, the pull rope provides additional support. When closed, the engagement of the first and second locking parts securely fixes the seat to the top of the suitcase, preventing it from accidentally coming off due to bumps or shaking during luggage handling.

[0030] In one embodiment, the housing further includes a first gripping part disposed on the top of the housing, and the seat has a hollow area corresponding to the first gripping part. In the closed state, the first gripping part is exposed through the hollow area.

[0031] With this design, the first grip is exposed through the cutout area when the seat is closed, ensuring that users can directly move suitcases through the first grip without disassembling or opening the seat. Attached Figure Description

[0044] Currently, the core function of suitcases on the market focuses on storage. However, when users need to rest temporarily while traveling or commuting, the suitcase itself cannot provide effective support. Users often have to find public seating or sit on the ground, making temporary rest inconvenient. To improve this, some suitcases have attempted to add auxiliary support components. However, these components are usually inextricably linked to the suitcase body, not only increasing the overall size and weight of the suitcase, making it inconvenient to carry and store, but also taking up extra space when the support components are not needed, affecting the normal pushing and storing of the suitcase.

[0045] To solve the above problems, such as Figures 1 to 5 As shown, this utility model discloses a suitcase that meets the user's temporary rest needs while improving the suitcase's portability and storage expansion capabilities.

[0046] like Figure 1 and Figure 4 As shown, this application provides a suitcase, including a seat 1, a case 2, and a rotating assembly 3, wherein: the seat 1 is detachably disposed on the top of the case 2, the seat 1 is rotatable relative to the case 2 about a preset axis, and has an open state and a closed state. In the open state, the seat 1 and the top of the case 2 form an accommodating space, and in the closed state, the seat 1 is in contact with the top of the case 2; the rotating assembly 3 includes a rotating shaft 31 extending along the preset axis and a rotating member 32 detachably disposed on the rotating shaft 31, the rotating member 32 is rotatable about the rotating shaft 31, and one of the rotating shaft 31 and the rotating member 32 is disposed on the case 2, and the other is disposed on the seat 1.

[0047] This design, with the detachable connection between seat 1 and the suitcase 2, allows users to choose to install or remove seat 1 as needed. Removing seat 1 reduces the overall size and weight of the suitcase, making it easier to carry either the suitcase or seat 1 separately, thus improving adaptability to different scenarios. Secondly, in the open state, seat 1 provides a resting space for the user, meeting their need for temporary rest. Furthermore, the rotation function of seat 1 around a preset axis allows the user to adjust the angle of seat 1 according to their resting posture, accommodating different sitting needs. Simultaneously, the storage space formed by seat 1 and the top of the suitcase 2 in the open state can additionally store personal items, expanding the suitcase's storage capacity and eliminating the need to carry additional storage bags. The design of the storage space in the closed state is based on the relative position of the seat 1 and the box 2. The seat 1's own structure creates an additional storage area without altering the original storage space of the box 2, improving practicality without increasing the overall size of the suitcase. Furthermore, in the closed state, the close fit between the seat 1 and the top of the box 2 ensures the overall neatness of the suitcase, preventing the seat 1 from protruding and taking up space, and not affecting the normal pushing and storing of the suitcase. This close fit design in the closed state eliminates gaps between the seat 1 and the top of the box 2 through direct contact, preventing collision noise caused by gaps during pushing, while also reducing overall space occupation, balancing functionality and portability. In addition, the cooperation between the rotating shaft 31 and the rotating component 32 provides a stable axial guide for the rotation of the seat 1, preventing offset and wobbling during rotation and ensuring stability for the user. Simultaneously, the rotating component 32 is detachably mounted on the rotating shaft 31, forming a linkage with the detachable connection between the seat 1 and the box 2. Users can easily disassemble the seat 1 by separating the rotating component 32 from the rotating shaft 31, a simple operation requiring no complicated tools.

[0048] Specifically, the rotation angle range of seat 1 can be designed according to actual needs.

[0049] In the illustrated embodiment, the extension direction of the preset axis is the width direction of the box 2.

[0050] In another implementation, depending on actual needs, the extension direction of the preset axis can also be designed as other directions such as the thickness direction of the box 2.

[0051] like Figure 1As shown, in one embodiment, the seat 1 includes a backrest 11 and baffles 12 disposed on both sides of the backrest 11. In the closed state, the two baffles 12 are fitted against the two sides of the suitcase 2, and the backrest 11 is fitted against the top surface of the suitcase 2. This configuration provides back support for the user when seated, preventing the user from leaning directly against the suitcase 2 and thus improving comfort and resting experience. The baffles 12, when closed, fit against the two sides of the suitcase 2, further filling the gap between the seat 1 and the suitcase 2, making the fit tighter and reducing shaking and collision noise during pushing. Simultaneously, the baffles 12 can cover the sides of the storage space when open, preventing the user resting on the seat 1 from falling and items in the storage space from falling out, improving storage safety. Furthermore, the fit between the backrest 11 and the top surface of the suitcase 2 ensures that the top of the suitcase is flat when closed, not affecting the user's ability to place other items.

[0052] The baffle 12 and the backrest 11 can be integrally formed or separately formed.

[0053] In the illustrated embodiment, the backrest 11 and the top surface of the housing 2 have the same dimensions, ensuring both a large working dimension of the backrest 11 and aesthetic appeal. In another embodiment, the dimensions of the backrest 11 can be designed to be larger or smaller than the top surface dimension of the housing 2, depending on actual needs.

[0054] In the illustrated embodiment, the baffle 12 is perpendicular to the chair back 11.

[0055] In another embodiment, the angle between the baffle 12 and the backrest 11 can be designed according to actual needs.

[0056] In another embodiment, the seat 1 includes only the backrest 11.

[0057] like Figure 1 and Figure 2 As shown, in one embodiment, the rotating shaft 31 is disposed on the top of the housing 2, and the rotating component 32 is disposed on the bottom of the seat 1 and has a rotating hole 321 extending along a preset axis. The rotating shaft 31 can extend into or out of the rotating hole 321 and can reciprocate within the rotating hole 321. With this configuration, the rotating shaft 31 is fixed to the top of the housing 2 and the rotating component 32 is fixed to the bottom of the seat 1, allowing the installation of the rotating component 3 to be closer to the connection surface of the two, reducing the suspended length of the component and improving rotational stability. The rotating hole 321 extends along the preset axis, providing precise rotational guidance for the rotating shaft 31, ensuring that the rotating component 32 rotates around the preset axis and preventing the seat 1 from rotating off-center. At the same time, the action of the rotating shaft 31 extending into or out of the rotating hole 321 directly realizes the detachment of the rotating component 3, thereby completing the disassembly of the seat 1 and the housing 2. The operation does not require additional tools, improving the convenience of disassembly.

[0058] In another embodiment, the rotating shaft 31 is disposed at the bottom of the seat 1, and the rotating component 32 is disposed at the top of the housing 2 and is provided with a rotating hole 321 extending along a preset axis. The rotating shaft 31 can extend into or out of the rotating hole 321 and can reciprocate within the rotating hole 321.

[0059] like Figures 1 to 3 As shown, in one embodiment, the suitcase also includes a disassembly assembly 4, which is located on the top of the suitcase body 2 and connected to a rotating shaft 31. The disassembly assembly 4 can drive the rotating shaft 31 to extend into or disengage from the rotating hole 321. This configuration, by introducing the disassembly assembly 4, achieves mechanized control of the seat 1 disassembly process. The disassembly assembly 4, connected to the rotating shaft 31, can precisely control the vertical travel of the rotating shaft 31, ensuring that it can reliably extend into the rotating hole 321 for rotational connection, or reliably disengage from the rotating hole 321 for quick disassembly. This avoids the difficulty of manually aligning and pulling out the shaft, providing an active and controlled disassembly method, and improving the convenience and safety of disassembly and installation.

[0060] like Figures 1 to 3 As shown, in one embodiment, the disassembly assembly 4 includes a pressing member 41, which is capable of reciprocating along a preset axis. A rotating shaft 31 is connected to the pressing member 41 and moves with it to extend into or disengage from the rotating hole 321. This configuration allows control of the rotating shaft 31's movement solely through the pressing member 41, lowering the operational threshold and improving the efficiency of installing or removing the seat 1. Simultaneously, the pressing member 41's movement along the preset axis, coaxial with the extension direction of the rotating shaft 31, ensures smooth movement of the rotating shaft 31, preventing movement deviation and further enhancing the smoothness of the disassembly operation.

[0061] like Figures 1 to 3 As shown, in one embodiment, the disassembly assembly 4 further includes a spring 42, which is disposed between the housing 2 and the pressing member 41. When the pressing member 41 moves toward the side away from the rotating member 32, the spring 42 is compressed and applies a force to the pressing member 41 to move toward the rotating member 32. With this configuration, the elastic force of the spring 42 can realize the automatic reset of the pressing member 41. After the user presses the pressing member 41 to disengage the rotating shaft 31 from the rotating hole 321 and removes the seat 1, the spring 42 can push the pressing member 41 to reset, driving the rotating shaft 31 back to the initial position of "extending into the rotating hole 321", simplifying the operation process. At the same time, the compression and reset process of the spring 42 can buffer the movement speed of the pressing member 41, preventing the pressing member 41 from colliding with the housing 2 due to excessive movement, and protecting the structural integrity of the pressing member 41 and the housing 2.

[0062] In another embodiment, the disassembly assembly 4 also includes structures such as pneumatic or hydraulic dampers, which, in addition to providing a reset force, can also control the reset speed of the rotating shaft 31.

[0063] In another implementation, the disassembly component 4 can be designed as a motor drive or other structures.

[0064] like Figures 1 to 3 As shown, in one embodiment, the disassembly assembly 4 further includes a limiting assembly 43. When the pressing member 41 moves toward the side away from the rotating member 32 until the rotating shaft 31 disengages from the rotating hole 321, the pressing member 41 and the limiting assembly 43 cooperate to limit its movement. With this configuration, the limiting assembly 43 can fix the pressing member 41 in its current position after the rotating shaft 31 disengages from the rotating hole 321. The user does not need to keep pressing the pressing member 41 to disassemble or install the seat 1, freeing up their hands and improving operational convenience. At the same time, the limiting action can prevent the spring 42 from pushing the pressing member 41 back to its original position and the rotating shaft 31 from re-entering the rotating hole 321 due to the user releasing their hand, ensuring the continuity of the disassembly or installation process and preventing operation interruption.

[0065] In another embodiment, the disassembly component 4 may also employ other designs such as electromagnetic locking or friction braking to maintain the disassembly state of the disassembly component 4.

[0066] In one embodiment, the limiting component 43 includes a return spring 431, an abutment 432, and a locking member 433. The locking member 433 is disposed on the top of the housing 2 and on the side of the pressing member 41 away from the rotating member 32. The abutment 432 is disposed between the pressing member 41 and the locking member 433 and is capable of reciprocating along a preset axis. The return spring 431 is disposed between the abutment 432 and the housing 2. When the pressing member 41 moves toward the side away from the rotating member 32 until the rotating shaft 31 disengages from the rotating hole 321, the abutment 432 is pushed by the pressing member 41 to engage with the locking member 433. When the pressing member 41 continues to move toward the side away from the rotating member 32, the return spring 431 is compressed and can apply a force to the abutment 432 to make it move toward the rotating member 32 and separate from the locking member 433. With this configuration, the "engagement-disengagement" process of the limiting component 43 is achieved through the step-by-step movement of the pressing member 41. The user only needs to press again to complete the operations of "disengaging the drive shaft 31", "engaging the abutment member 432", and "disengaging and resetting the abutment member 432", without the need for additional operation of the limiting component 43, thus simplifying the operation process. The reset spring 431 can automatically push the abutment member 432 to separate when the pressing member 41 continues to move, ensuring that the limiting state can be flexibly released and preventing the limiting component 43 from jamming and causing the pressing member 41 to be unable to reset. At the same time, the locking member 433 is located away from the rotating part of the pressing member 41. On one side of component 32, interference with the rotating assembly 3 is avoided, ensuring that each component works independently. In addition, to unlock and reset the rotating shaft 31, the user needs to apply a pushing force to the pressing component 41 again. This extra stroke will compress the reset spring 431, causing the abutment component 432 to separate from the locking component 433. Then, the spring 42 drives the rotating shaft 31 to reset quickly. This design provides clear operational feedback and additional safety, ensuring that the connection is restored only when the user clearly intends to reset the connection, effectively preventing accidental restoration of the connection due to vibration or accidental touch during operation.

[0067] In another embodiment, the engagement state between the abutment member 432 and the latching member 433 can also be maintained or changed by other designs such as electromagnetic locking or friction braking.

[0068] like Figures 3 to 5As shown, in one embodiment, the suitcase further includes a cover 5 that covers the outside of the rotating component 3 and the disassembly component 4, with at least a portion of the pressing component 41 extending out of the cover 5. This arrangement isolates the rotating component 3 and the disassembly component 4 from the external environment, preventing dust, rainwater, and debris from entering the components, avoiding corrosion and jamming, and extending the service life of the rotating component 3 and the disassembly component 4. Simultaneously, the cover 5 enhances the aesthetics of the suitcase's top structure, conceals internal mechanical parts, and improves the suitcase's overall appearance. The fact that at least a portion of the pressing component 41 extends out of the cover 5 ensures that the user can operate the pressing component 41 normally, preventing the disassembly component 4 from becoming unusable due to the cover 5, thus balancing protection and ease of operation.

[0069] like Figure 4 and Figure 5 As shown, in one embodiment, the top of the suitcase away from the suitcase body 2 has a first abutment 51, and the seat 1 near the rotating component 3 has a second abutment 13. In the open state, the first abutment 51 and the second abutment 13 abut against each other. This arrangement allows the abutment of the first abutment 51 and the second abutment 13 to set a fixed limit position for the open state of the seat 1, preventing the seat 1 from rotating excessively away from the suitcase body 2. This prevents the seat 1 from becoming loose from the rotating component 3 due to excessive rotation angle, or from the suitcase tipping over due to a shift in the center of gravity, protecting the connection structure between the seat 1 and the suitcase body 2. It also ensures the stability of the seat 1's angle when the user is seated, improving passenger safety. Furthermore, the abutment engagement does not require an additional locking structure; the limiting effect can be achieved through mechanical contact, resulting in a simple and reliable structure that reduces manufacturing costs.

[0070] In the illustrated embodiment, the first abutment 51 is disposed on the shield 5, and the second abutment 13 is disposed on the backrest 11. In other embodiments, depending on actual needs, the first abutment 51 may be arranged at other positions such as the top edge or center of the housing 2; the second abutment 13 may be arranged at other positions such as the bottom of the baffle 12.

[0071] like Figure 4As shown, in one embodiment, the suitcase also includes a pull rod 6 and a pull rope 7. The pull rod 6 is telescopically positioned on the side of the suitcase 2 away from the rotating component 3. In the open state, with the pull rod 6 extending beyond the top of the suitcase 2, the two ends of the pull rope 7 are detachably connected to the pull rod 6 and the seat 1, respectively. This telescopic design of the pull rod 6 allows the user to adjust its extension length according to the height of the seat 1 when it is open, ensuring the pull rope 7 remains taut. The detachable connection at both ends of the pull rope 7 allows the user to easily remove it when not needed, preventing it from tangling with other components. In the open state, the pull rope 7 provides additional support to the seat 1, distributing the pressure of the seat 1 on the rotating component 3 and preventing damage to the rotating component 3 due to excessive stress over a long period, while also increasing the load-bearing capacity of the seat 1. Furthermore, the support of the pull rope 7 reduces the swaying of the seat 1, making the user's seating more stable. The pull rope 7, pull rod 6, and seat 1 form a closed space, preventing items placed on the top of the suitcase 2 from falling or users resting on the top of the suitcase 2 from falling.

[0072] like Figure 1 and Figure 4 As shown, in one embodiment, the suitcase 2 further includes a first latching part 21, and the seat 1 further includes a second latching part 14. In the closed state, the first latching part 21 and the second latching part 14 engage. This configuration ensures that the engagement of the first latching part 21 and the second latching part 14 in the closed state firmly fixes the seat 1 to the top of the suitcase 2, preventing the seat 1 from accidentally coming off due to bumps or shaking during luggage pushing, thus ensuring stability in the closed state. Simultaneously, the latching operation is simple; the user only needs to rotate the seat 1 to the closed state for automatic engagement, eliminating the need for additional locking steps and improving ease of use. Furthermore, the latching structure enhances the fit between the seat 1 and the suitcase 2, further reducing the gap between them and preventing collision noise. Specifically, the first latching part 21 is a protrusion, and the second latching part 14 is a hole corresponding to the first latching part 21.

[0073] In another embodiment, the second latching portion 14 is a protrusion, and the first latching portion 21 is a hole corresponding to the first latching portion 21.

[0074] In another embodiment, depending on actual needs, the first snap-fit ​​portion 21 and the second snap-fit ​​portion 14 can be designed as other structures such as snap-fit ​​and sliding groove.

[0075] In the illustrated embodiment, one end of the pull rope 7 is threaded through the second locking part 14, and the other end is locked to the pull rod 6.

[0076] In another embodiment, when closed, the housing 2 and the seat 1 can be designed with magnetic attraction to prevent the seat 1 from falling off.

[0077] like Figure 1As shown, in one embodiment, the case 2 further includes a first gripping part 22, which is disposed on the top of the case 2. The seat 1 has a hollow area 15 corresponding to the first gripping part 22. In the closed state, the first gripping part 22 is exposed through the hollow area 15. With this configuration, the first gripping part 22 is exposed through the hollow area 15 in the closed state, ensuring that the user can directly carry the suitcase through the first gripping part 22 without disassembling or opening the seat 1, without affecting the normal carrying function of the suitcase. At the same time, the setting of the hollow area 15 does not require changing the position and structure of the first gripping part 22. It only requires opening a corresponding area on the seat 1, which is simple in design and does not increase manufacturing costs. In addition, the hollow area 15 can reduce the weight of the seat 1 and improve the portability of the seat 1.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
