Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a roof reinforcement structure, a carriage, and a rail vehicle. Background Technology

[0002] Existing rail transit vehicles, such as high-speed trains, subways, and light rail, typically require new manufacturing technologies that balance vehicle safety, lightweight design, high strength, and aesthetic appeal to meet the requirements of exterior design and lightweight body. To meet the protection requirements of the car roof, the upper part of the car usually has a roof reinforcement structure. In related technologies, the roof reinforcement structure constitutes at least part of the car roof or serves as a reinforcement structure or interior structure of the car roof, typically including an inner support plate and an outer support plate. The inner and outer support plates are connected by multiple threaded connectors. Using threaded connectors requires through holes in the inner or outer support plates for the threaded connectors to pass through, which can easily affect the sealing and structural strength of the roof reinforcement structure. Furthermore, the disassembly and assembly process requires tightening multiple threaded connectors, making disassembly and assembly time-consuming. Summary of the Invention

[0003] This invention provides a roof reinforcement structure, a carriage, and a rail vehicle to solve or improve the defects in related technologies where the two support plates of the roof reinforcement structure are connected by multiple threaded connectors, which can easily affect the sealing and structural strength of the roof reinforcement structure and make disassembly and assembly time-consuming. This invention reduces the adverse effects of the connectors between the two support plates on the sealing and structural strength of the roof reinforcement structure and improves the disassembly and assembly efficiency of the roof reinforcement structure.

[0004] This invention provides a ceiling reinforcement structure, including a first support plate, a second support plate, a column structure, and a cylindrical structure;

[0005] The outer side wall of the column structure has a protrusion, and the inner side wall of the cylindrical structure has a concave portion for engaging with the protrusion. Both the column structure and the cylindrical structure are disposed between the first support plate and the second support plate, and one of the column structure and the cylindrical structure is connected to the first support plate, while the other is connected to the second support plate.

[0006] According to a ceiling reinforcement structure provided by the present invention, the protrusion is configured as a spherical structure, and correspondingly, the concave portion is configured as a spherical hole;

[0007] Alternatively, the protrusion may be configured as an annular protrusion, a beaded structure, or a bump, and correspondingly, the concave portion may be configured as a groove.

[0008] According to the present invention, a ceiling reinforcement structure further includes a support structure, which is supported between a first support plate and a second support plate. The support structure is provided with a positioning hole through which a corresponding cylindrical structure passes. The positioning hole cooperates with the corresponding cylindrical structure to position the support structure.

[0009] According to the present invention, a ceiling reinforcement structure is provided, wherein the support structure includes a plurality of support units arranged in an array, the support units are polygonal structures, and each support unit is provided with at least two positioning holes.

[0010] According to a ceiling reinforcement structure provided by the present invention, the support unit has a first groove in the middle, the first groove extending from one of the first support plate and the second support plate toward the other and penetrating the support unit;

[0011] And / or, the side of the support unit is provided with a second groove, the second groove extending from one of the first support plate and the second support plate toward the other and penetrating the support unit.

[0012] According to the present invention, a roof reinforcement structure is provided, wherein the supporting structure is a frame structure.

[0013] According to the present invention, a ceiling reinforcement structure is provided in which the hollow area of ​​the frame structure is filled with sound insulation cotton.

[0014] According to the present invention, a ceiling reinforcement structure further includes a reinforcing rib, wherein at least one of the first support plate and the second support plate is provided with a slot on its outer side, the reinforcing rib is provided with a locking block, the reinforcing rib is connected to the outer side of the first support plate or the outer side of the second support plate, and the locking block of the reinforcing rib extends into the corresponding slot.

[0015] According to a ceiling reinforcement structure provided by the present invention, at least one side of the reinforcing rib is provided with an ear plate, and the ear plate is connected to the first support plate or the second support plate by a connector;

[0016] Alternatively, the reinforcing rib may be welded or bonded to the first support plate or the second support plate.

[0017] The present invention also provides a carriage, including the roof reinforcement structure as described above.

[0018] The present invention also provides a rail vehicle, including the roof reinforcement structure as described above or the carriage as described above.

[0019] This invention provides a ceiling reinforcement structure. A first support plate and a second support plate are connected by a column structure and a cylindrical structure disposed between them. The cylindrical structure allows the column structure to extend into it, and its inner wall has a recessed portion that engages with a protrusion of the column structure. During assembly, the column structure of one of the first and second support plates is aligned with the cylindrical structure of the other, and then the column structure is pressed into the cylindrical structure, causing the protrusion of the column structure to engage with the recessed portion within the cylindrical structure, thus completing the assembly of the ceiling reinforcement structure. When it is necessary to disassemble the first and second support plates, the first support plate can be lifted from the second support plate, overcoming the engaging force between the protrusion and the recessed portion, allowing the column structure to detach from the cylindrical structure, thus completing the disassembly of the ceiling reinforcement structure.

This eliminates the need for through holes in the first and second support plates for connecting components to pass through, thus ensuring the sealing performance and structural strength of both plates. Furthermore, during assembly and disassembly, the column structure can be simply pressed into or pulled out of the cylindrical structure, eliminating the need for twisting, making operation more convenient and improving assembly and disassembly efficiency.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0033] In related technologies, ceiling reinforcement structures typically include an inner support plate and an outer support plate. The inner and outer support plates are connected by multiple threaded connectors. Using threaded connectors requires opening through holes in either the inner or outer support plate for the connectors to pass through, which can easily affect the sealing and structural strength of the ceiling reinforcement structure. In addition, multiple threaded connectors need to be tightened during disassembly and assembly, making the process time-consuming.

[0034] To address or improve the shortcomings of existing ceiling reinforcement structures where two support plates are connected by multiple threaded connectors, which can easily affect the sealing and structural strength of the ceiling reinforcement structure and result in time-consuming disassembly and assembly, this invention provides a ceiling reinforcement structure to reduce the impact of the connectors between the two support plates on the sealing and structural strength of the ceiling reinforcement structure and to improve the disassembly and assembly efficiency of the ceiling reinforcement structure.

[0035] The following is combined Figures 1-7 The ceiling reinforcement structure provided in the embodiments of the present invention is described.

[0036] Specifically, the roof reinforcement structure includes a first support plate 1, a second support plate 2, a column structure 3, and a cylindrical structure 4.

[0037] The cylindrical structure 4 is used to allow the column structure 3 to extend into it. The outer wall of the column structure 3 has a protrusion 301, and the inner wall of the cylindrical structure 4 has a recess 401 for engaging with the protrusion 301. Both the column structure 3 and the cylindrical structure 4 are disposed between the first support plate 1 and the second support plate 2, and one of the column structure 3 and the corresponding cylindrical structure 4 is connected to the first support plate 1, while the other is connected to the second support plate 2. Optionally, to ensure the connection strength between the first support plate 1 and the second support plate 2, multiple cylindrical structures 4 and multiple column structures 3 are provided between the first support plate 1 and the second support plate 2.

[0038] In an embodiment of the present invention, a ceiling reinforcement structure is provided. During assembly, the column structure 3 of one of the first support plate 1 and the second support plate 2 is aligned with the cylindrical structure 4 of the other. The column structure 3 is then pressed into the cylindrical structure 4, and the protrusion 301 of the column structure 3 engages with the concave portion 401 within the cylindrical structure 4, thereby completing the assembly of the ceiling reinforcement structure. When it is necessary to disassemble the first support plate 1 and the second support plate 2, the first support plate 1 can be lifted from the second support plate 2, overcoming the engaging force between the protrusion 301 and the concave portion 401, allowing the column structure 3 to disengage from the cylindrical structure 4, thereby completing the disassembly of the ceiling reinforcement structure.

[0039] With this configuration, the canopy reinforcement structure provided in this embodiment of the invention connects the first support plate 1 and the second support plate 2 through the interlocking action of the column structure 3 and the cylindrical structure 4. This eliminates the need for through holes in the first and second support plates 1 and 2 for connecting components to pass through, thus ensuring the sealing performance and structural strength of the first and second support plates 1 and 2. Furthermore, during assembly and disassembly, the column structure 3 can be simply pressed into or pulled out of the cylindrical structure 4, eliminating the need for twisting, making operation more convenient and improving assembly and disassembly efficiency.

[0040] In some embodiments provided by the present invention, the roof reinforcement structure constitutes at least part of the roof of the carriage, or the roof reinforcement structure serves as a reinforcement structure for the carriage roof, or the roof reinforcement structure serves as an interior panel of the carriage roof.

[0041] Optionally, when the roof reinforcement structure is installed in the carriage, both the first support plate 1 and the second support plate 2 are connected to the main body of the carriage. The column structure 3 and the cylindrical structure 4 engage, which on the one hand ensures that the relative positions of the first support plate 1 and the second support plate 2 are fixed, reducing the problem of the first support plate 1 and the second support plate 2 moving around during installation, so as to facilitate the installation of the roof reinforcement structure.

[0042] On the other hand, the column structure 3 and the cylindrical structure 4 are connected between the first support plate 1 and the second support plate 2, which can connect the first support plate 1 and the second support plate 2 into one unit, improve the rigidity of the first support plate 1 and the second support plate 2, and reduce the problem of the first support plate 1 and the second support plate 2 bending inward or outward. The "inward" side refers to the side of the first support plate 1 and the second support plate 2 that are close to each other, and the "outward" side refers to the side of the first support plate 1 and the second support plate 2 that are far apart from each other.

[0043] Furthermore, both the first support plate 1 and the second support plate 2 are fixedly connected to the main body of the carriage. Alternatively, both the first support plate 1 and the second support plate 2 are detachably connected to the main body of the carriage. Alternatively, one of the first support plate 1 and the second support plate 2 is detachably connected to the main body of the carriage, while the other is fixedly connected to the main body of the carriage. The fixed connection allows for a higher connection strength between the first support plate 1 or the second support plate 2 and the main body of the carriage, while the detachable connection facilitates the removal and replacement of the first support plate 1 or the second support plate 2.

[0044] Optionally, the fixed connection can be a welded connection or a riveted connection, and the detachable connection can be a threaded connection.

[0045] In some embodiments of the present invention, the ceiling reinforcement structure further includes a support structure 5. The support structure 5 is supported between a first support plate 1 and a second support plate 2, and the support structure 5 is provided with positioning holes 502 for the corresponding cylindrical structure 4 to pass through. When the cylindrical structure 4 passes through the positioning holes 502, it can position the support structure 5.

[0046] In this embodiment, the support structure 5 is used to support and limit the first support plate 1 and the second support plate 2, thereby increasing the rigidity of both the first support plate 1 and the second support plate 2 and reducing the problem of the first support plate 1 and the second support plate 2 bending inward.

[0047] By setting positioning holes 502 in the support structure 5, the column structure 3 can be avoided, and the cylindrical structure 4 can be inserted into the positioning holes 502 to achieve the effect of positioning the support structure 5, thereby reducing the problem of the support structure 5 shifting.

[0048] In some embodiments provided by this invention, the support structure 5 is configured as a frame structure. The frame structure can be configured as a single, integral structure.

[0049] In this embodiment, by setting the support structure 5 as a frame structure, the mass of the support structure 5 can be reduced while ensuring the support effect of the support structure 5 on the first support plate 1 and the second support plate 2, thereby achieving the effect of lightweighting of the roof reinforcement structure.

[0050] Alternatively, in order to achieve a lightweight effect for the roof reinforcement structure, the frame structure can be set as an aluminum alloy structure or a carbon fiber structure.

[0051] Alternatively, in order to achieve a lightweight effect for the roof reinforcement structure, the first support plate 1 and the second support plate 2 can be set as aluminum alloy plates or carbon fiber plates.

[0052] In some embodiments provided by the present invention, the hollow area of ​​the frame structure is filled with sound insulation cotton 8.

[0053] In this embodiment, filling the hollow area of ​​the frame structure with sound-insulating cotton 8 can improve the utilization rate of the hollow area of ​​the frame structure without increasing the thickness of the ceiling reinforcement structure. On the other hand, by filling with sound-insulating cotton 8, both the sound insulation performance and the heat insulation performance of the ceiling reinforcement structure can be improved.

[0054] In some embodiments provided by the present invention, the support structure 5 includes a plurality of support units 501 arranged in an array. The support units 501 are configured as polygonal structures, and each support unit 501 is provided with at least two positioning holes 502.

[0055] In this embodiment, the support structure 5 includes multiple support units 501 arranged in an array. By setting multiple support units 501, the support effect on the first support plate 1 and the second support plate 2 can be improved. In addition, when the areas of the first support plate 1 and the second support plate 2 change, by increasing or decreasing the number of support units 501, the support structure 5 can be better adapted to the first support plate 1 and the second support plate 2, ensuring a better support effect.

[0056] like Figure 3 As shown, optionally, the support unit 501 can be configured as a rectangular structure. The support units 501 configured as rectangular structures are arranged in both directions, and there is a spacing between two adjacent support units 501 in the same row or column.

[0057] In this embodiment, by setting the support unit 501 as a rectangular structure, and having a gap between adjacent support units 501 in the row and column, the gap between adjacent support units 501 will change when the ceiling reinforcement structure is bent. By having a certain gap between adjacent support units 501, the two adjacent support units 501 will not interfere with each other during the bending process of the ceiling reinforcement structure.

[0058] Furthermore, since there is a gap between adjacent support units 501 in each row and column, when the size of the ceiling reinforcement structure is large, it can be cut along the gap between the support units 501, making the use of the ceiling reinforcement structure more flexible and convenient. In addition, when opening holes in the ceiling reinforcement structure for embedding other components, holes can also be made along the gaps between the support units 501.

[0059] Of course, the support unit 501 can also be a triangle, pentagon or hexagon.

[0060] In some embodiments provided by the present invention, a first groove 503 is provided in the middle of the support unit 501. The first groove 503 extends along one of the first support plate 1 and the second support plate 2 towards the other and passes through the support unit 501.

[0061] In this embodiment, by providing a first groove 503 in the middle of the support unit 501, the weight of the support unit 501 can be reduced, thereby achieving the effect of lightweighting the roof reinforcement structure.

[0062] Furthermore, sound-insulating cotton 8 is provided inside the first groove 503.

[0063] In this embodiment, filling the first groove 503 of the support unit 501 with sound-insulating cotton 8 can improve the utilization rate of the internal space of the support unit 501 without increasing the thickness of the ceiling reinforcement structure. On the other hand, by filling with sound-insulating cotton 8, both the sound insulation performance and the heat insulation performance of the ceiling reinforcement structure can be improved.

[0064] Optionally, the first groove 503 can be a circular groove or a polygonal groove.

[0065] In some embodiments provided by the present invention, the side of the support unit 501 is provided with a second groove 504, which extends along one of the first support plate 1 and the second support plate 2 toward the other and passes through the support unit 501.

[0066] In this embodiment, by providing a second groove 504 on the side of the support unit 501, the weight of the support unit 501 can be reduced, thereby achieving the effect of lightweighting the roof reinforcement structure.

[0067] Furthermore, each side of the support unit 501 is provided with a second groove 504, and the side of the support unit 501 is arranged opposite to the side of the adjacent support unit 501, that is, the second grooves 504 of the two adjacent support units 501 are arranged opposite to each other, and sound insulation cotton 8 is provided in the second grooves 504 of the two adjacent support units 501.

[0068] In this embodiment, filling the two oppositely arranged second grooves 504 of two adjacent support units 501 with sound-insulating cotton 8 can improve the utilization rate of the space between adjacent support units 501 without increasing the thickness of the ceiling reinforcement structure. On the other hand, by filling with sound-insulating cotton 8, both the sound insulation performance and the heat insulation performance of the ceiling reinforcement structure can be improved.

[0069] Optionally, the second groove 504 is a circular groove or a polygonal groove.

[0070] refer to Figure 3 As shown, the support unit 501 further includes a first groove 503 in the middle and a second groove 504 on the side. Thus, the support unit 501 itself forms an integral frame structure, while the support structure 5, which includes multiple support units 501, forms an assembled frame structure, thereby making the support unit 501 lighter.

[0071] Furthermore, both the first groove 503 and the second groove 504 are filled with sound-insulating cotton 8. This increases the amount of sound-insulating cotton 8 filling the support structure 5, thereby further improving the sound insulation and heat insulation performance of the ceiling reinforcement structure.

[0072] In some embodiments provided by this invention, the column structure 3 is configured as a cylindrical structure, and correspondingly, the cylindrical structure 4 is configured as a cylindrical structure, with a one-to-one correspondence between the column structure 3 and the cylindrical structure 4. This configuration simplifies the structure of the column structure 3 and the cylindrical structure 4, making them easier to manufacture.

[0073] Furthermore, the column structure 3 can be threadedly connected to the first support plate 1 or the second support plate 2. For example, the inner side of the first support plate 1 or the inner side of the second support plate 2 is provided with a threaded blind hole, and the outer side of the column structure 3 is provided with a threaded engagement with the threaded blind hole. This allows the height of the column structure 3 extending out of the threaded blind hole to be adjusted, making it easier for the column structure 3 to engage with the cylindrical structure 4.

[0074] Alternatively, the column structure 3 can be connected to the first support plate 1 or the second support plate 2 by bonding or welding. Furthermore, to increase the connection strength between the column structure 3 and the first support plate 1 or the second support plate 2, blind holes can be provided on the inner side of the first support plate 1 or the second support plate 2, with the column structure 3 extending into the blind holes and bonded or welded to the first support plate 1 or the second support plate 2. This makes the structure of the column structure 3, the first support plate 1, and the second support plate 2 relatively simple, thereby reducing manufacturing difficulty and cost.

[0075] It is understandable that the connection between the cylindrical structure 4 and the first support plate 1 or the second support plate 2 can be referenced to the connection between the column structure 3 and the first support plate 1 or the second support plate 2, and will not be elaborated further.

[0076] In some embodiments provided by the present invention, the protrusion 301 of the column structure 3 is configured as a spherical structure, and correspondingly, the concave portion 401 of the cylindrical structure 4 is configured as a spherical hole. That is, the protrusion 301 of the column structure 3 extends into the cylindrical structure 4 and engages with the spherical hole of the cylindrical structure 4.

[0077] In this embodiment, during the bending process of the ceiling reinforcement structure, the first support plate 1 and the second support plate 2 will have different curvatures. Therefore, the inner sides of the first support plate 1 and the inner sides of the second support plate 2 will be relatively offset, causing the column structure 3 to tilt relative to the cylindrical structure 4. The column structure 3 engages with the spherical hole of the cylindrical structure 4 through a ball-head structure. During the bending process of the ceiling reinforcement structure, the ball-head structure can tilt relative to the spherical hole while maintaining engagement with it, thus producing an adaptive effect. This reduces the problem of excessive interaction force between the column structure 3 and the cylindrical structure 4, which could lead to stress concentration and damage.

[0078] Of course, the protrusion 301 of the column structure 3 is not limited to being a spherical structure; for example, the protrusion 301 can also be an annular protrusion. Alternatively, the protrusion 301 can be a beaded structure, which protrudes from the surface of the column structure 3 under the action of an elastic element. Correspondingly, the concave portion 401 of the cylindrical structure 4 is a groove provided on the inner wall of the cylindrical structure 4.

[0079] In some embodiments of the present invention, the column structure 3 is configured as an elastic structure. For example, the column structure 3 is made of an elastic material, including rubber or plastic. With this configuration, during the insertion of the column structure 3 into the cylindrical structure 4, the column structure 3 can deform and engage with the recessed portion 401 of the cylindrical structure 4. Furthermore, configuring the column structure 3 as an elastic structure can reduce the transmission of vibration between the first support plate 1 and the second support plate 2, thereby reducing noise.

[0080] Of course, to enable the column structure 3 to engage with the cylindrical structure 4, it is not limited to setting the column structure 3 as an elastic structure. For example, in other embodiments provided by the present invention, the side wall of the cylindrical structure 4 is provided with at least two through grooves, which are distributed circumferentially along the cylindrical structure 4. The through grooves penetrate the cylindrical wall of the cylindrical structure 4 and extend to the end of the cylindrical structure 4 into which the column structure 3 extends. That is, the cylindrical structure 4 is set as an expansion sleeve.

[0081] With this configuration, after the column structure 3 extends into the cylindrical structure 4, it can expand the cylindrical structure 4, allowing the cylindrical structure 4 to abut against the inner wall of the positioning hole 502 of the support structure 5. In other words, the cylindrical structure 4 can tighten the positioning hole 502, thereby reducing the problem of the support structure 5 shaking due to the gap between the cylindrical structure 4 and the positioning hole 502, and improving the stability of the support structure 5.

[0082] Of course, column structure 3 is not limited to being a cylindrical structure, and cylindrical structure 4 is not limited to being a cylindrical structure. For example, see reference. Figure 7 As shown, in other embodiments provided by the present invention, the column structure 3 is configured as a cuboid structure, and correspondingly, the cylindrical structure 4 is configured as a square tube structure. The protrusion 301 is a protrusion provided on the surface of the column structure 3, and the concave portion 401 is a groove provided in the cylindrical structure 4. Optionally, the cylindrical structure 4 can correspond one-to-one with the column structure 3, or one cylindrical structure 4 can cooperate with at least two column structures 3.

[0083] Furthermore, in order to enable the column structure 3 to engage with the cylindrical structure 4, the column structure 3 is configured as an elastic structure. Alternatively, the side wall of the cylindrical structure 4 is provided with at least two through slots, which are distributed circumferentially along the cylindrical structure 4. The through slots penetrate the cylindrical wall of the cylindrical structure 4 and extend to the end of the cylindrical structure 4 into which the column structure 3 extends.

[0084] In some embodiments provided by the present invention, all column structures 3 are disposed on the first support plate 1, and all cylindrical structures 4 are disposed on the second support plate 2.

[0085] In this embodiment, the first support plate 1 has only column structure 3 and the second support plate 2 has only cylindrical structure 4. Therefore, in the manufacturing process, it is only necessary to install all column structures 3 on the first support plate 1 and all cylindrical structures 4 on the second support plate 2. That is, the same structure is installed on the support plate, which makes the installation easier and more efficient.

[0086] Of course, the arrangement of the column structure 3 and the cylindrical structure 4 is not limited to the column structure 3 being all located on the first support plate 1 and the cylindrical structure 4 being all located on the second support plate 2. For example, in other embodiments provided by the present invention, the first support plate 1 is provided with both column structure 3 and cylindrical structure 4. Correspondingly, the second support plate 2 is provided with cylindrical structure 4 at positions corresponding to the column structure 3 of the first support plate 1, and the second support plate 2 is provided with column structure 3 at positions corresponding to the cylindrical structure 4 of the first support plate 1.

[0087] refer to Figure 1 and Figure 2As shown, in some embodiments of the present invention, the ceiling reinforcement structure further includes a reinforcing rib 6. At least one of the first support plate 1 and the second support plate 2 has a slot 7 on its outer side, and the reinforcing rib 6 has a locking block 601. The reinforcing rib 6 is connected to the outer side of the first support plate 1 or the outer side of the second support plate 2, and the locking block 601 of the reinforcing rib 6 extends into the corresponding slot 7. Optionally, the locking block 601 is a T-shaped block, and the slot 7 is a T-shaped groove into which the locking block 601 can extend.

[0088] In this embodiment, by providing a locking block 601 for the reinforcing rib 6, the thickness of the reinforcing rib 6 is increased, thereby increasing its stiffness. This allows the reinforcing rib 6 to improve the stiffness and strength of the first support plate 1 or the second support plate 2, resulting in better structural performance of the ceiling reinforcement structure. Furthermore, the locking block 601 is positioned within the locking groove 7, minimizing the portion of the reinforcing rib 6 protruding beyond the first support plate 1 or the second support plate 2. This reduces the overall dimensions of the ceiling reinforcement structure and minimizes interference between the reinforcing rib 6 and other components. In addition, the engagement of the locking block 601 with the locking groove 7 increases the contact area between the reinforcing rib 6 and the first support plate 1 or the second support plate 2, resulting in higher connection strength and reducing the risk of detachment. This allows the reinforcing rib 6 to provide better reinforcement and strengthening effects for the first support plate 1 or the second support plate 2.

[0089] In some embodiments provided by the present invention, at least one side of the reinforcing rib 6 is provided with an ear plate 602, and the ear plate 602 is connected to the first support plate 1 or the second support plate 2 through a connector.

[0090] Furthermore, multiple ear plates 602 are provided on both sides of the reinforcing rib 6, and each ear plate 602 is connected to the first support plate 1 or the second support plate 2 via a connector. This arrangement can improve the connection strength between the reinforcing rib 6 and the first support plate 1 or the second support plate 2.

[0091] Optionally, the ear plate 602 is connected to the first support plate 1 or the second support plate 2 via a threaded connector to facilitate the installation and removal of the reinforcing rib 6.

[0092] Of course, the reinforcing rib 6 is not limited to being connected to the first support plate 1 or the second support plate 2 via a connector. For example, in other embodiments provided by the present invention, the reinforcing rib 6 is welded or bonded to the first support plate 1 or the second support plate 2.

[0093] This invention also provides a carriage.
