Description

Technical Field

[0001] This application relates to the field of transportation technology, and more particularly to a frame box. Background Technology

[0002] In logistics transportation and cargo turnover, frame containers are widely used in long-distance transportation and warehousing of various items such as machinery, large parts, and building materials due to their advantages such as structural stability, strong protection, and ease of hoisting.

[0003] In related technologies, the chassis of a flat rack container, as the core component bearing the weight of the goods, is usually made of metal. However, metal is heavy, resulting in a high proportion of the chassis's weight and thus increasing the overall mass of the container. During transportation, vehicles have fixed load limits; an excessively heavy chassis directly reduces the effective load-bearing capacity of the goods, decreasing the cargo capacity for a single trip. Simultaneously, heavier flat rack containers increase the energy consumption of the transportation vehicle, significantly raising transportation costs. Utility Model Content

[0004] To overcome the problems existing in related technologies, this application provides a frame box.

[0005] According to this application, a frame box is provided, comprising: A base frame for carrying items, the base frame comprising: Multiple support beams, wherein the multiple support beams are arranged at intervals along a first direction, the support beams comprising: A support extending along a second direction perpendicular to the first direction, wherein the support is made of resin; A first fabric strip is embedded in the support and integrally formed with the support, and the first fabric strip extends along the second direction.

[0006] In some embodiments of this application, the first fabric strip is woven from multiple fiber bundles.

[0007] In some embodiments of this application, the fiber bundle is configured as a glass fiber bundle.

[0008] In some embodiments of this application, the support body includes a first side plate, a second side plate, a third side plate, and a fourth side plate connected end to end in sequence, wherein the extending directions of the first side plate, the second side plate, the third side plate, and the fourth side plate are all the same as the second direction.

[0009] In some embodiments of this application, the base frame further includes: A reinforcing rod, wherein multiple supporting beams are sequentially inserted through the reinforcing rod along the first direction.

[0010] In some embodiments of this application, the base frame further includes: At least two support components, each support component including multiple support beams arranged in parallel, with a gap space between adjacent support components, a reinforcing rod passing through the gap space, and a locking structure provided around the reinforcing rod, the locking structure being provided at both ends of the reinforcing rod and / or the portion of the reinforcing rod corresponding to the gap space.

[0011] In some embodiments of this application, the support component includes: A loading platform is disposed on top of the support beam and covers the support beam.

[0012] In some embodiments of this application, the carrier plate includes: A matrix extending along a second direction, wherein the matrix is ​​made of resin; The second fabric strip is embedded in the substrate and integrally formed with the substrate, and the second fabric strip extends along the second direction.

[0013] In some embodiments of this application, the frame box further includes: A connecting frame, wherein the connecting frame is disposed at at least one of the opposite ends in a second direction of the base frame; The side frame is rotatably connected to the connecting frame so that the side frame can rotate toward or away from the base frame.

[0014] In some embodiments of this application, both the connecting frame and the side frame are made of metal.

[0015] The technical solutions provided by the embodiments of this application may include the following beneficial effects: The frame box provided in this application reduces the overall weight of the base frame by using resin as the material for the support beams. Compared with existing metal base frames, resin base frames are lighter, which helps reduce the total weight of the frame box, reduce transportation energy consumption, and increase the cargo loading capacity of a single transport under the same load limit. It also helps improve the corrosion resistance of the base frame and extend the service life of the frame box. By setting the first fabric strip embedded in the support body, the structural strength of the support body with the first fabric strip embedded in it can be increased, thereby improving the structural strength and load-bearing stability of the support beam. At the same time, it can also enhance the impact resistance and fatigue resistance of the support beam, further extending the service life of the frame box.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and feature vectors in the embodiments of this application can be arbitrarily combined with each other.

[0021] In related technologies, the chassis of a flat rack container, as the core component bearing the weight of the goods, is usually made of metal. However, metal is heavy, resulting in a high proportion of the chassis's weight and thus increasing the overall mass of the container. During transportation, vehicles have fixed load limits; an excessively heavy chassis directly reduces the effective load-bearing capacity of the goods, decreasing the cargo capacity for a single trip. Simultaneously, heavier flat rack containers increase the energy consumption of the transportation vehicle, significantly raising transportation costs.

[0022] To address the above problems, this application provides a frame box, which includes a base frame for carrying goods. The base frame includes multiple support beams, each support beam comprising a support body and a first fabric strip. The support body extends along a second direction, perpendicular to the first direction, and is made of resin. The first fabric strip is embedded in and integrally formed with the support body, extending along the second direction. By using resin as the material for the support beams, the overall weight of the base frame is reduced. Compared to existing metal base frames, the base frame of this application is lighter, which helps reduce the total weight of the frame box, increase the cargo loading capacity per transport, and reduce transport energy consumption. Furthermore, the first fabric strip embedded in the support body improves the structural strength and load-bearing stability of the support beams, while also enhancing their impact and fatigue resistance, thus extending the service life of the frame box.

[0023] An exemplary embodiment of this application provides a frame box, see [link to example]. Figure 1 The frame box 10 includes a base frame 1 for carrying items. The length direction of the base frame 1 is a second direction, and the base frame 1 extends along the second direction. For example, the second direction is parallel to the horizontal direction, so that the base frame 1 can carry items on a horizontal surface.

[0024] See Figures 1-4 as well as Figure 7The base frame 1 includes multiple support beams 11, which are spaced apart along a first direction parallel to the horizontal plane and perpendicular to a second direction. Each support beam 11 includes a support body 111 and a first fabric strip 112. The support body 111 extends along the second direction and is made of resin. The first fabric strip 112 is embedded in the support body 111 and integrally formed with it, extending along the second direction. Exemplarily, the first fabric strip 112 and the support body 111 can be integrally formed by thermosetting pultrusion. The thermosetting pultrusion process ensures that the first fabric strip 112 and the support body 111 form a stable overall structure, which is beneficial for improving the structural strength of the support beam 11. Exemplarily, in... Figure 7 In this case, the first fabric strip 112 can be embedded inside the support body 111, or the first fabric strip 112 can be embedded on the surface of the support body 111.

[0025] In this embodiment, by using resin as the material for the support beam 11, the overall weight of the base frame 1 is reduced. Compared with the existing metal base frame 1, the resin base frame 1 is lighter, which helps to reduce the total weight of the frame box 10, reduce transportation energy consumption, and increase the cargo loading capacity of a single transport under the same load limit. It also helps to improve the corrosion resistance of the base frame 1 and extend the service life of the frame box 10. By setting the first fabric strip 112 embedded in the support body 111, the structural strength of the support body 111 with the first fabric strip 112 embedded is higher, thereby improving the structural strength and load-bearing stability of the support beam 11. At the same time, it can also enhance the impact resistance and fatigue resistance of the support beam 11, further extending the service life of the frame box 10.

[0026] In some embodiments, see Figure 7 and Figure 9 The first fabric strip 112 is woven from multiple fiber bundles 1121. The first fabric strip 112 woven from the fiber bundles 1121 has the characteristics of high strength and high modulus, which can significantly improve the load-bearing capacity and deformation resistance of the support beam 11 while maintaining the overall lightweight structure of the support beam 11.

[0027] In some embodiments, see Figure 9 Since at least some of the fiber bundles 1121 extend in different directions, the support beam 11 has high structural strength in different directions, thereby effectively improving the overall deformation resistance of the support beam 11.

[0028] In some embodiments, the fiber bundle 1121 is a glass fiber bundle. Glass fiber bundles have strong chemical stability, are not easily deformed or aged, and are not easily affected by changes in environmental humidity and temperature, ensuring that the support beam 11 maintains stable structural performance over a long period of time. At the same time, glass fiber bundles have good compatibility with resin materials, and can be better embedded in the support body 111 during thermosetting pultrusion molding, further improving the overall load-bearing reliability of the support beam 11.

[0029] In some embodiments, see Figures 5-7 The support body 111 includes a first side plate 1111, a second side plate 1112, a third side plate 1113, and a fourth side plate 1114 connected end to end. The first side plate 1111 and the third side plate 1113 are arranged opposite each other in the vertical direction, and the second side plate 1112 and the fourth side plate 1114 are arranged opposite each other in the first direction. The first side plate 1111, the second side plate 1112, the third side plate 1113, and the fourth side plate 1114 enclose a hollow part, which helps to reduce the amount of material used in the support body 111. To reduce the weight of the base frame 1, the extension directions of the first side plate 1111, the second side plate 1112, the third side plate 1113, and the fourth side plate 1114 are all the same as the second direction. The first fabric strip 112 extends along the second direction so that when the first fabric strip 112 is embedded in the first side plate 1111, the second side plate 1112, the third side plate 1113, and the fourth side plate 1114, the length of the first fabric strip 112 can be made longer, thereby improving the overall structural strength of the support 111 in the second direction.

[0030] In some embodiments, see Figures 5-7 The support body 111 also includes a first partition plate 1115 and a second partition plate 1116. The first partition plate 1115 and the second partition plate 1116 are disposed in the hollow part. The first partition plate 1115 and the second partition plate 1116 are spaced apart and parallel in the vertical direction. The two ends of the first partition plate 1115 are respectively connected to the second side plate 1112 and the fourth side plate 1114. The two ends of the second partition plate 1116 are respectively connected to the second side plate 1112 and the fourth side plate 1114. This design facilitates the improvement of the structural strength of the support beam 11, thereby improving the reliability and stability of the base frame 1 in carrying items.

[0031] In some embodiments, see Figures 1-6The base frame 1 also includes reinforcing rods 12, and multiple reinforcing rods 12 can be provided. In the second direction, multiple reinforcing rods 12 are arranged sequentially at intervals. In the first direction, multiple support beams 11 are sequentially inserted through the reinforcing rods 12. The reinforcing rods 12 sequentially pass through the interior of multiple support beams 11 to connect the multiple support beams 11, thereby enhancing the structural strength of the base frame 1. When the base frame 1 partially bears an object, the weight of the object can be transferred to the reinforcing rods 12 through the support beams 11, and then distributed to the adjacent support beams 11 by the reinforcing rods 12. This avoids deformation of a single support beam 11 due to local overload, thereby enhancing the load-bearing capacity of the frame box 10.

[0032] In some embodiments, see Figures 3-7 The base frame 1 also includes at least two support components 13, each comprising multiple parallel support beams 11. These parallel support beams 11 enhance the load-bearing capacity of the frame box 10. When the base frame 1 bears the weight of items, the multiple support beams 11 increase the structural strength of the support component 13, preventing a single support beam 11 from bending or breaking due to overload, and preventing dents or deformation of the loading plate 131. For example, the support component 13 includes six parallel support beams 11. A spacer 5 is provided between adjacent support components 13, the length of which in a first direction is greater than the distance between adjacent support beams 11 within the support component 13. A reinforcing rod 12 passes through at least two support components 13 and the spacer 5 between adjacent support components 13 to connect adjacent support components 13 together, enhancing the overall structural strength of the base frame 1.

[0033] See Figures 1-7 A locking structure 2 is provided around the reinforcing rod 12. The locking structure 2 is located at both ends of the reinforcing rod 12 and / or at the corresponding interval space 5. The locking structure 2 is used to connect the locking device to fix the carried items. The two ends of the reinforcing rod 12 are located at the edge of the frame box 10, providing a large installation and operating space. At the same time, the portion of the reinforcing rod 12 corresponding to the interval space 5 also provides a large installation and operating space. Setting the locking structure 2 at both ends of the reinforcing rod 12 and / or at the corresponding interval space 5 facilitates the connection of the locking device to the locking structure 2, making user operation more convenient and improving the ease of fixing items with the locking device.

[0034] In some embodiments, see Figures 4-7The locking structure 2 includes a connecting part 21 and a ring part 22. One end of the connecting part 21 is rotatably connected to the reinforcing rod 12, and the other end of the connecting part 21 is connected to the ring part 22. This design allows the connecting part 21 to rotate according to the tension force of the locking device when the locking structure 2 is subjected to the tension force, thereby adaptively adjusting the angle to match the direction of the tension force of the locking device and avoiding damage to the locking structure 2 due to excessive local stress caused by the deviation of the tension direction. For example, the ring part 22 can be configured as a ring structure, and the connection between the connecting part 21 and the ring part 22 can be either a rotatable connection or a fixed connection.

[0035] In some embodiments, see Figures 3-6 The support assembly 13 includes a carrying plate 131, which is disposed on top of the support beam 11 and covers the support beam 11. The support beam 11 provides stable support to the carrying plate 131. The carrying plate 131 covers the support beam 11, thereby covering the gap between adjacent support beams 11, so that the support assembly 13 forms a complete bearing surface, reducing the risk of items shaking or colliding due to uneven bearing surfaces.

[0036] In some embodiments, see Figure 8 The loading platform 131 includes a base 1311 and a second fabric strip 1312. The base 1311 extends along a second direction and is made of resin. Compared with the existing metal loading platform 131, the resin loading platform 131 is lighter, which helps to reduce the weight of the base frame 1, thereby reducing the total weight of the frame box 10, reducing transportation energy consumption, and increasing the cargo loading capacity of a single transport under the same load limit. It also helps to improve the corrosion resistance of the loading platform 131, thereby increasing the service life of the frame box 10. The second fabric strip 1312 is embedded in the base 1311 and formed integrally with the base 1311. The second fabric strip 1312 extends along the second direction and can be thermosetting and pultruded with the base 1311 to form an integral structure, which makes the structural strength and load-bearing stability of the loading platform 131 higher. At the same time, it can also enhance the impact resistance and fatigue resistance of the loading platform 131, further extending the service life of the frame box 10. For example, the second fabric strip 1312 may be embedded inside the substrate 1311, or the second fabric strip 1312 may be embedded on the surface of the substrate 1311.

[0037] In some embodiments, see Figure 1 and Figure 10The frame box 10 also includes a connecting frame 3 and a side frame 4. The connecting frame 3 is located at at least one end of the base frame 1 in a second direction, and is connected to the base frame 1. The side frame 4 is rotatably connected to the connecting frame 3, meaning the side frame 4 is located at at least one end of the base frame 1 in a second direction. The side frame 4 can rotate towards or away from the base frame 1, thus allowing it to be erected or laid flat. See also Figure 1 When the side frame 4 is erected, it can restrain the goods carried on the frame container 10, preventing them from falling out of the frame container 10. See also Figure 10 The side frame 4 can be laid flat to reduce the space occupied by the side frame 4 in the height direction of the frame box 10, making it easier to stack multiple frame boxes 10, thereby reducing the space occupied by the frame box 10 in the transportation.

[0038] In some embodiments, both the connecting frame 3 and the side frame 4 are made of metal, which can prevent deformation or damage at the connection point caused by long-term opening and closing of the side frame 4, and ensure that the blocking effect of the side frame 4 on the goods is stable and reliable when it is erected. After the side frame 4 is laid flat, the metal connecting frame 3 and the side frame 4 can help to stably support the weight of the upper stacked frame box 10, prevent the frame box 10 from breaking during stacking, and improve the safety of multi-box stacking transportation.
