Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a luggage structure. Background Technology

[0002] As an indispensable storage tool for modern travel, suitcases are designed to provide users with a convenient and efficient solution for carrying their belongings. They typically consist of two shells connected by a specific rotating mechanism to open and close, providing travelers with space to store essentials such as clothing, food, and personal care items. However, in actual use, existing suitcases generally face a pressing problem—insufficient closure stability.

[0003] Specifically, when a suitcase is loaded with a large number or heavy items, the structure of the suitcase often cannot withstand the resulting enormous internal pressure. This can cause the connection between the lid and the body to loosen or even develop gaps during lifting or moving. This problem not only affects the suitcase's sealing and security but can also cause unnecessary trouble and losses for travelers due to leaks or damage to the suitcase.

[0004] In particular, when lifting a suitcase full of items by the handle, the connection between the lid and the body is more easily squeezed or stretched due to gravity or uneven weight distribution of the items inside the suitcase, which exacerbates the problem of the lid not closing securely. Utility Model Content

[0005] In view of this, the present invention provides a suitcase structure to solve the problem that gaps easily appear at the lid when the suitcase is lifted in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention provides a luggage structure, which includes a first shell, a second shell, a handle assembly, and a reinforcing assembly.

[0009] As an embodiment of this utility model, when the handle assembly does not exert force on the first housing, the reinforcing assembly is relatively parallel to the inner wall of the second housing and there is a preset distance between them.

[0010] As an embodiment of the present invention, the first housing includes a first body and a first frame, and the second housing includes a second body and a second frame. The first frame is connected to the opening edge of the first body, and the second frame is connected to the opening edge of the second body. The first frame and the second frame are rotatably connected.

[0011] As an embodiment of this utility model, the first frame is provided with a protrusion at the end opposite to the first body, and the second frame is provided with a groove that cooperates with the protrusion at the end opposite to the second body. The protrusion is engaged in the groove so that the first shell and the second shell are closed.

[0012] As an embodiment of the present invention, the first frame is provided with a groove at the end opposite to the first body, and the second frame is provided with a protrusion that cooperates with the groove at the end opposite to the second body. The protrusion is engaged in the groove so that the first shell and the second shell are closed.

[0013] As an embodiment of the present invention, the luggage structure further includes at least two sets of hinges. Each set of hinges includes two hinge pieces and a hinge pin. The two hinge pieces are respectively fixed to the side walls of the first frame and the second frame, and the two hinge pieces are rotatably connected by the hinge pin.

[0014] As one embodiment of the present invention, the handle assembly includes a connecting seat and a handle. The connecting seat is fixed to the outer side wall of the first frame or the first body, and the handle is rotatably connected to the connecting seat.

[0015] As an embodiment of the present invention, the suitcase structure further includes a combination lock, one end of which is fixed to the outer side wall of the first frame or the first body and is on the same side as the connecting seat, and the other end is locked to the second frame or the second body.

[0016] As an embodiment of this utility model, the suitcase also includes a plurality of rivets, the first frame and the second frame are respectively connected to the first body and the second body by the rivets, and the number of the rivets is a preset number.

[0017] In one embodiment of this utility model, the reinforcing component is fixed to the bottom of the handle component by screws passing through the first housing.

[0018] As one embodiment of this utility model, the first reinforcing plate is two separate curved baffles, the two separate curved baffles respectively corresponding to the bottom two sides of the handle assembly; or the first reinforcing plate is a single integral curved baffle, the two sides of the single integral curved baffle respectively corresponding to the bottom two sides of the handle assembly.

[0019] As one embodiment of this utility model, the second reinforcing plate is two separate straight baffles, the two separate straight baffles respectively corresponding to the bottom two sides of the handle assembly; or the second reinforcing plate is a single integrated straight baffle, the two sides of the single integrated straight baffle respectively corresponding to the bottom two sides of the handle assembly.

[0020] Compared with the prior art, the suitcase structure provided in this embodiment of the utility model has the following advantages:

[0021] 1. In the luggage structure provided by this utility model, a reinforcing component is provided on the inner side wall of the first shell, corresponding vertically to the handle component on the outer side wall of the first shell. When the first and second shells are closed and the luggage is lifted by the handle component, the reinforcing component generates an upward force, allowing it to abut against the inner side wall of the second shell. This provides stable support for the first and second shells, reinforcing their closure and effectively preventing gaps from forming between their openings. Therefore, the luggage structure provided by this utility model effectively solves the problem in the prior art where gaps easily appear at the lid when the luggage is lifted.

[0022] 2. In the luggage structure provided by this utility model, the main body of the first reinforcing piece protrudes and bends on both sides to form a connecting part and a first baffle part, respectively. The bending direction of the connecting part is opposite to the bending direction of the first baffle part. The connecting part can be stably fixed to the inner wall of the first shell by a connector. The first baffle part spans the opening and closing point between the first shell and the second shell. When the first shell and the second shell are closed and the luggage is lifted, the first baffle part can generate abutment or fit force on the second shell to make it close firmly, preventing gaps from appearing at the closing point. Structurally, the bending of the first reinforcing piece forms a stable structure, thereby improving the resistance of the first reinforcing piece to the closing point of the luggage.

[0023] 3. In the luggage structure provided by this utility model, one side of the second reinforcing piece protrudes to form a second baffle portion, which can stably fix the second reinforcing piece to the inner side wall of the first shell. The second baffle portion spans the opening and closing point between the first shell and the second shell. When the first shell and the second shell are closed and the luggage is lifted, the second baffle portion can generate abutment or fit force on the second shell to make it close firmly, preventing gaps from appearing at the closing point. Structurally, the second reinforcing piece bends to form a stable structure, thereby improving the resistance of the second reinforcing piece to the closing point of the luggage.

[0024] 4. In the luggage structure provided by this utility model, when the handle assembly is in its natural state, the handle assembly does not exert force on the first shell, and there is a gap between the reinforcing assembly and the inner wall of the second shell, which enables the reinforcing assembly to prevent gaps from appearing when the luggage is lifted without affecting the opening and closing of the luggage.

[0025] 5. In the luggage structure provided by this utility model, one end of the first frame is connected to the opening edge of the first body, and one end of the second frame is connected to the opening edge of the second body. The adjacent side walls of the first frame and the second frame are rotatably connected. The first frame and the second frame can provide support for the first shell and the second shell, thereby enhancing the overall structural strength of the luggage and effectively resisting external impacts and pressure.

[0026] 6. In the luggage structure provided by this utility model, the protrusions and grooves cooperate to form a stitching-like mechanism, which enables the first shell and the second shell to fit tightly together to form a compact and stable whole. It provides additional stability and fixation when the first shell and the second shell are closed, and also helps to reduce gaps inside the luggage, thereby improving its sealing performance. In addition, the mechanism of protrusions and grooves is simpler than the traditional zipper or buckle method, improving the user experience.

[0027] 7. In the luggage structure provided by this utility model, the first frame and the second frame are rotatably connected by a hinge pin, which ensures that the first shell and the second shell have stable rotational performance at the connection point. This enables the luggage structure to achieve a stable rotational connection, enhances the structural strength and durability, provides a smooth opening and closing experience, enhances the stability when closing, improves the overall structural reliability, and plays an important role in facilitating maintenance and replacement. As a result, the luggage structure is more practical, durable, and reliable, meeting the various needs of users in travel and daily life.

[0028] 8. In the suitcase structure provided by this utility model, the two ends of the handle are rotatably connected to the connecting seat, which allows users to adjust the handle to different angles as needed to adapt to different carrying postures and height requirements, making the suitcase more flexible during carrying and improving user comfort.

[0029] 9. The suitcase structure provided by this utility model, by adding a combination lock, allows users to control the opening permissions of the suitcase, providing security for users and ensuring that the items inside the suitcase are not taken or stolen by unauthorized persons, bringing users a safer, more convenient and reliable suitcase usage experience.

[0030] 10. The luggage structure provided by this utility model is characterized by simple and quick operation through rivet connection, which can greatly shorten the assembly time and improve work efficiency. If a rivet fails or is damaged, it can be easily removed and replaced with a new rivet without large-scale disassembly and reconstruction of the entire structure. In addition, rivets of different shapes, sizes and colors can be selected to match the overall design style and aesthetic requirements of the luggage structure.

[0031] 11. In the luggage structure provided by this utility model, screws are passed through the first housing to fix the fixing component to the bottom of the handle component. The connection and fixation between the reinforcement component and the first housing are achieved by screws, which can improve the convenience of disassembling and installing the reinforcement component. It can also install different types of reinforcement components as needed, and improve the compatibility of the first housing with the reinforcement component. Attached Figure Description

[0057] Example 1

[0058] Please see Figure 1 As shown, the first embodiment of this utility model discloses a suitcase structure 1, which includes a first shell 11, a second shell 12, a handle assembly 13, and a reinforcing assembly 14. The first shell 11 and the second shell 12 are closable. The handle assembly 13 is disposed on the outer side wall of the first shell 11. The first end of the reinforcing assembly 14 is disposed on the inner side wall of the first shell 11. The reinforcing assembly 14 and the handle assembly 13 are vertically corresponding. The second end of the reinforcing assembly 14 crosses the opening and closing point between the first shell 11 and the second shell 12. When the handle assembly 13 exerts a force on the first shell 11, the reinforcing assembly 14 abuts against the inner side wall of the second shell 12.

[0059] Specifically, the first housing 11 and the second housing 12 can be opened and rotated along two adjacent side walls as a central axis. The handle assembly 13 can be provided on the outer side wall of the first housing 11 or the second housing 12, and the reinforcing assembly 14 corresponding to the position of the handle assembly 13 is provided on the inner side wall of the corresponding first housing 11 or the second housing 12.

[0060] Optionally, the number of handle components 13 and reinforcing components 14 is not less than two sets.

[0061] For ease of understanding, this utility model is specifically described using two sets of handle components 13 and reinforcing components 14 as an example, but this should not be construed as limiting the utility model. The two sets of handle components 13 are respectively disposed on two adjacent outer sidewalls of the first housing 11, near the opening of the first housing 11, while the two sets of reinforcing components 14 are disposed vertically on two adjacent inner sidewalls of the first housing 11, corresponding to the positions of the handle components 13.

[0062] It is understood that when the suitcase structure 1 is closed, that is, when the first shell 11 and the second shell 12 are closed, and the suitcase is lifted by the handle assembly 13, the reinforcing assembly 14 will generate an upward force, allowing the reinforcing assembly 14 to abut against the inner wall of the second shell 12. This provides stable support for the first shell 11 and the second shell 12, reinforcing the closure of the first shell 11 and the second shell 12 and effectively preventing gaps from forming between the openings of the first shell 11 and the second shell 12. Therefore, the suitcase structure 1 provided by this utility model effectively solves the problem in the prior art where gaps easily appear at the lid when the suitcase is lifted.

[0063] Furthermore, the reinforcement component 14 is fixed to the bottom of the handle component 13 by screws passing through the first housing 11. The connection and fixation between the reinforcement component 14 and the first housing 11 is achieved by screws, which can improve the convenience of disassembly and installation of the reinforcement component 14. It can also install different types of reinforcement components 14 as needed, and improve the compatibility of the first housing 11 with the reinforcement component 14.

[0064] Furthermore, please combine Figure 1 and Figure 2 As shown, the reinforcing component 14 includes a first reinforcing piece 141. The two sides of the first reinforcing piece 141 are bent to form a connecting part 1411 and a first baffle part 1412, respectively. The bending direction of the connecting part 1411 is opposite to the bending direction of the first baffle part 1412. The connecting part 1411 is connected to the inner wall of the first housing 11. The first baffle part 1412 is parallel to the connecting part 1411 and protrudes from the plane of the opening of the first housing 11 connected to the connecting part 1411, and crosses the opening between the first housing 11 and the second housing 12. When the handle component 13 exerts force on the first housing 11, the first baffle part 1412 abuts against the inner wall of the second housing 12.

[0065] Optionally, the first reinforcing plate 141 may be made of a sturdy material, such as metal or other sturdy materials like hard plastic, which is not specifically limited herein.

[0066] Specifically, the first reinforcing piece 141 is a curved sheet structure. Its main body 1413 protrudes and bends on both sides to form a connecting part 1411 and a first baffle part 1412, respectively. The bending direction of the connecting part 1411 is opposite to that of the first baffle part 1412. The connecting part 1411 can be stably fixed to the inner wall of the first housing 11 by a connector. The first baffle part 1412 protrudes from the plane of the opening of the first housing 11 and spans the opening and closing point between the first housing 11 and the second housing 12. When the first housing 11 and the second housing 12 are closed, the first baffle part 1412 can exert a force to abut or adhere to the second housing 12 when the suitcase is lifted, so that it is firmly closed, preventing gaps from appearing at the closing point. Structurally, the bending of the first reinforcing piece 141 forms a stable structure, thereby improving the resistance of the first reinforcing piece 141 to the closing point of the suitcase.

[0067] Optionally, the first reinforcing plate 141 is two separate curved baffles 142, which correspond to the bottom two sides of the handle assembly 13 respectively; or the first reinforcing plate 141 is a single integrated curved baffle 143, which corresponds to the bottom two sides of the handle assembly 13 respectively.

[0068] In one implementation, the first reinforcing plate 141 consists of two separate curved baffles 142. Please refer to... Figure 2 and Figure 3 As shown, the two split curved baffles 142 correspond to the bottom sides of the handle assembly 13, respectively. The overall thickness L1 of the split curved baffle 142 is 2-6mm, the length L2 of the connecting part 1411 of the split curved baffle 142 is 15-25mm, the length L3 of the main body part 1413 is 2-10mm, the length L4 of the first baffle part 1412 is 15-35mm, and the radius of the rounded corner connecting the main body part 1413 with the connecting part 1411 and the first baffle part 1412 is 2-4mm. The overall length of the split curved baffle 142 is 40-70mm. The first baffle part 1412 can also be trapezoidal.

[0069] In another embodiment, the first reinforcing plate 141 is an integral curved baffle 143. Please refer to... Figure 4 and Figure 5 As shown, the two sides of the integrated curved baffle 143 correspond to the bottom two sides of the handle assembly 13 respectively. The overall thickness of the integrated curved baffle 143 is the same as the overall thickness of the split curved baffle 142, which is 2-6mm. The overall length L5 of the integrated curved baffle 143 is 150-200mm. The first baffle part 1412 can also be trapezoidal.

[0070] Furthermore, when the handle assembly 13 is in its natural state, there is a gap between the reinforcing assembly 14 and the inner wall of the second housing 12.

[0071] It is understandable that when the handle assembly 13 is in its natural state, that is, when the handle assembly 13 does not exert any force on the first housing 11, and there is a gap between the reinforcing assembly 14 and the inner wall of the second housing 12, the reinforcing assembly 14 can prevent gaps from appearing when the suitcase is lifted, while not affecting the opening and closing of the suitcase.

[0072] Further, please refer to Figure 6 As shown, the luggage structure 1 also includes at least two hinge 15s. Each hinge 15 includes two hinge pieces 151 and a hinge pin 152. The two hinge pieces 151 are fixed to the side walls of the first frame 112 and the second frame 122 respectively, and the two hinge pieces 151 are rotatably connected by the hinge pin 152.

[0073] Specifically, in each hinge 15, the two hinge pieces 151 are fixed to the side walls of the first frame 112 and the second frame 122 respectively, and are rotatably connected by the hinge pin 152. This ensures that the first shell 11 and the second shell 12 have stable rotational performance at the connection point, enabling the luggage structure 1 to achieve a stable rotational connection, enhancing structural strength and durability, providing a smooth opening and closing experience, enhancing stability when closing, improving the overall structural reliability, and facilitating maintenance and replacement. As a result, the luggage structure 1 is more practical, durable, and reliable, meeting the various needs of users in travel and daily life.

[0074] Further, please refer to Figure 7 As shown, the first housing 11 includes a first body 111 and a first frame 112, and the second housing 12 includes a second body 121 and a second frame 122. The first frame 112 is connected to the opening edge of the first body 111, and the second frame 122 is connected to the opening edge of the second body 121. The first frame 112 and the second frame 122 are rotatably connected.

[0075] Specifically, both the first body 111 and the second body 121 are box structures with openings. The first shell 11 is composed of the first body 111 and the first frame 112. Specifically, one end of the frame of the first frame 112 is connected to the opening edge of the first body 111. The second shell 12 is composed of the second body 121 and the second frame 122. Specifically, one end of the frame of the second frame 122 is connected to the opening edge of the second body. The adjacent side walls of the first frame 112 and the second frame 122 are rotatably connected.

[0076] More specifically, the first frame 112 and the second frame 122 are made of a sturdy material, such as metal or hard plastic. By setting the first frame 112 and the second frame 122 to the opening edges of the first body 111 and the second body 121 respectively, support can be provided for the first shell 11 and the second shell 12, enhancing the overall structural strength of the suitcase and effectively resisting external impacts and pressure.

[0077] In one embodiment, the first frame 112 has a protrusion 1121 at one end opposite to the first body 111, and the second frame 122 has a groove 1221 at one end opposite to the second body 121 that cooperates with the protrusion 1121. The protrusion 1121 is engaged in the groove 1221 so that the first housing 11 and the second housing 12 are closed.

[0078] In another embodiment, the first frame 112 has a groove 1221 at the end opposite to the first body 111, and the second frame 122 has a protrusion 1121 that mates with the groove 1221 at the end opposite to the second body 121. The protrusion 1121 is engaged in the groove 1221 so that the first housing 11 and the second housing 12 are closed. That is, the protrusion 1121 can also be provided at the end opposite to the second body 121 of the second frame 122, while the groove 1221 is provided at the end opposite to the first body 111 of the first frame 112. In this utility model, the protrusion 1121 being provided in the first frame 112 is used as an example for specific description, but this should not be construed as limiting the utility model.

[0079] More specifically, the protrusion 1121 of the first frame 112 and the groove 1221 of the second frame 122 cooperate to form a stitching mechanism, which enables the first shell 11 and the second shell 12 to fit tightly together to form a compact and stable whole. This provides additional stability and fixation when the first shell 11 and the second shell 12 are closed, and also helps to reduce gaps inside the suitcase, thereby improving its sealing performance. Furthermore, the mechanism of the protrusion 1121 and the groove 1221 is simpler than traditional zipper or buckle methods, improving the user experience.

[0080] For further information, please refer to [link / reference]. Figure 7 As shown, the handle assembly 13 includes a connecting seat 131 and a handle 132. The connecting seat 131 is fixed to the outer side wall of the first frame 112 or the second frame 122. The handle 132 is rotatably connected to the connecting seat 131. In some embodiments, the connecting seat 131 can also be fixed to the outer side wall of the first body 111 or the second body 121.

[0081] Specifically, the handle 132 has an arch-shaped or bow-shaped structure, and its two ends are rotatably connected to the left and right connecting seats 131 via pins. This allows users to adjust the handle 132 to different angles as needed to adapt to different carrying postures and height requirements, making the suitcase more flexible during carrying and improving user comfort.

[0082] Furthermore, the connecting seat 131 is located in the middle of the outer side wall of the first frame 112, and the reinforcing component 14 is located in the inner side wall of the first frame 112, corresponding to the position of the connecting seat 131.

[0083] Specifically, the connecting seat 131 and the reinforcing component 14 are located in the middle of the side wall of the first frame 112. The optimized position of the handle component 13 makes it easier and less strenuous for users to lift and move the suitcase. It also ensures that the reinforcing component 14 has the best support effect when lifting the suitcase, and the force is evenly distributed, reducing the risk of frame deformation or gaps at the closure caused by uneven force distribution.

[0084] Furthermore, the suitcase structure 1 also includes a combination lock 16. In one embodiment, one end of the combination lock 16 is fixed to the outer wall of the first frame 112 and on the same side as the connecting seat 131, and the other end is locked to the second frame 122. In another embodiment, one end of the combination lock 16 is fixed to the outer wall of the first body 111 and on the same side as the connecting seat 131, and the other end is locked to the second body 121. In this utility model, the example of one end of the combination lock 16 being fixed to the outer wall of the first frame 112 is used for specific description, but this should not be construed as limiting the utility model.

[0085] Specifically, the suitcase structure 1 is equipped with a combination lock 16, which allows users to control the opening permissions of the suitcase, providing security and ensuring that the items inside the suitcase are not taken or stolen by unauthorized persons, thus bringing users a safer, more convenient and reliable suitcase experience.

[0086] Furthermore, the first frame 112 and the second frame 122 are connected to the first body 111 and the second body 121 by rivets 17, and the number of rivets 17 is a preset number.

[0087] Specifically, the connection via rivets 17 is simple and quick to operate, which can greatly shorten assembly time and improve work efficiency. If a rivet 17 malfunctions or is damaged, it can be easily removed and replaced with a new rivet 17 without large-scale disassembly and reconstruction of the entire structure. In addition, rivets 17 of different shapes, sizes, and colors can be selected to match the overall design style and aesthetic requirements of the suitcase structure 1.

[0088] Optionally, the number of rivets 17 is 10-100.

[0089] In this utility model, when the luggage structure 1 is 20 inches, the number of rivets 17 is 10-70, and the spacing between the rivets 17 is 3-18cm; when the luggage structure 1 is 28 inches, the number of rivets 17 is 30-100, and the spacing between the rivets 17 is 3-18cm.

[0090] Example 2

[0091] Please see Figure 8 As shown, the second embodiment of this utility model discloses a suitcase structure 2. The suitcase structure 2 disclosed in the second embodiment is generally the same as the suitcase structure 2 disclosed in the first embodiment. The parts that are the same will not be described again here. The main difference is that the reinforcing component 24 includes a second reinforcing piece 241. The second reinforcing piece 241 is connected to the inner wall of the first housing 21. One side of the second reinforcing piece 241 protrudes to form a second baffle portion 2411. The second baffle portion 2411 spans the opening and closing point between the first housing 21 and the second housing 22. When the handle component 23 exerts a force on the first housing 21, the second baffle portion 2411 abuts against the inner wall of the second housing 22.

[0092] Optionally, the second reinforcing piece 241 may be made of a sturdy material, such as metal or other sturdy materials like hard plastic, which is not specifically limited herein.

[0093] Specifically, the second reinforcing piece 241 is a straight sheet structure with one side protruding to form a second baffle portion 2411, which can stably fix the second reinforcing piece 241 to the inner wall of the first housing 21. The second baffle portion 2411 protrudes from the plane of the opening of the first housing 21 and spans the opening and closing point between the first housing 21 and the second housing 22. When the first housing 21 and the second housing 22 are closed and the suitcase is lifted, the second baffle portion 2411 can generate abutment or fit force on the second housing 22 to make it close firmly, preventing gaps from appearing at the closure. Structurally, the second reinforcing piece 241 bends to form a stable structure, thereby improving the resistance of the second reinforcing piece 241 to the closure point of the suitcase.

[0094] Optionally, the second reinforcing plate 241 is two separate straight baffles 242, which correspond to the bottom two sides of the handle assembly 23 respectively; or the second reinforcing plate 241 is a single integrated straight baffle 243, which corresponds to the bottom two sides of the handle assembly 23 respectively.

[0095] In one implementation, the second reinforcing plate 241 consists of two separate straight baffles 242. Please refer to... Figure 9 and Figure 10As shown, two separate straight baffles 242 respectively correspond to both sides of the bottom of the handle assembly 23. The separate straight baffle 242 is a short strip-shaped structure in a "convex" shape. The overall thickness of the separate straight baffle 242 is 2 - 6 mm, the overall height H1 is 30 - 60 mm, the length H2 of the upper short side is 15 - 55 mm, and the length H3 of the lower long side is 40 - 70 mm. In the embodiment of the present utility model, the upper short side H2 is specifically 30 mm, the length H3 of the lower long side is specifically 55 mm, the overall height H1 is specifically 34 mm, and the side short side H4 is specifically 18 mm.

[0096] As another implementation manner, the second reinforcing piece 241 is an integral straight baffle 243. Please refer to Figure 11 and Figure 12 As shown, both sides of the integral straight baffle 243 respectively correspond to both sides of the bottom of the handle assembly 23. The integral straight baffle 243 is a long strip-shaped structure in a "convex" shape. The overall thickness of the integral straight baffle 243 is 2 - 6 mm, the length H5 is 150 - 200 mm, and the width H6 is 30 - 60 mm.

[0097] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, 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, it should be considered as the scope described in this specification.

[0098] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
