[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] Example 1: This example provides a tray panel structure, such as... Figures 1-3As shown, the device includes a first fixing plate 1, a support plate 2, a panel 4, and a second fixing plate 5. One side of the support plate 2 has a mounting groove 3. There are two support plates 2, symmetrically distributed at both ends of the first fixing plate 1. Both ends of the panel 4 are respectively inserted into the two mounting grooves 3. At least one panel 4 is sequentially arranged along the support plate 2 from the end closest to the first fixing plate 1 towards the end furthest from the first fixing plate 1. Both ends of the second fixing plate 5 are detachably connected to the two mounting grooves 3, and the second fixing plate 5 is attached to the side of the panel 4 furthest from the first fixing plate 1.

[0033] For example, during implementation, a mounting groove 3 is provided on one side of the support plate 2, and the mounting groove 3 extends from one end of the support plate 2 to the other end of the support plate 2. There are two support plates 2, and the two support plates 2 are symmetrically arranged with the openings of the mounting grooves 3 facing each other.

[0034] The two ends of the first fixing plate 1 are respectively installed in the two mounting slots 3, and the ends of the first fixing plate 1 are connected to one end of the support plate 2 by welding, screwing or integral molding.

[0035] The two ends of the panel 4 are respectively adapted to the two mounting slots 3. The number of panels 4 is at least one, and the panel 4 can slide along the mounting slot 3 from the end away from the first fixing plate 1 to the end of the mounting slot 3 closer to the first fixing plate 1 until the panel 4 is attached to the first fixing plate 1.

[0036] The two ends of the second fixing plate 5 are respectively adapted to the two mounting slots 3, and the second fixing plate 5 can slide along the mounting slot 3 towards the end of the first fixing plate 1 closer to the first fixing plate 1 until the second fixing plate 5 is attached to the side of the panel 4 away from the first fixing plate 1, and the second fixing plate 5 is detachably connected to the support plate 2 by means of screwing, riveting, snapping, etc.

[0037] During use, determine the initial number of panels 4 as needed. Insert both ends of the first panel 4 into the two mounting slots 3 respectively, and slide the first panel 4 along the mounting slot 3 from the end away from the first fixing plate 1 towards the end of the mounting slot 3 closer to the first fixing plate 1 until the first panel 4 is in contact with the first fixing plate 1. Next, insert both ends of the second panel 4 into the two mounting slots 3 respectively, and slide the second panel 4 along the mounting slot 3 from the end away from the first fixing plate 1 towards the end of the mounting slot 3 closer to the first fixing plate 1 until the side of the first panel 4 away from the first fixing plate 1 is in contact with the first panel 4. Repeat the above steps until all the panels 4 of the initial number are inserted into the mounting slots 3. Next, insert both ends of the second fixing plate 5 into the two mounting slots 3 respectively, and slide the second fixing plate 5 along the mounting slot 3 from the end away from the first fixing plate 1 towards the end of the mounting slot 3 closer to the first fixing plate 1 until the second fixing plate 5 is in contact with the side of the last panel 4 away from the first fixing plate 1. At this point, the second fixing plate 5 and the support plate 2 are detachably connected by means of bolt connection, pin riveting, snap-fit, etc.

[0038] On the one hand, when the size of the tray panel 4 needs to be adjusted, the second fixing plate 5 can be removed, and the number of panels 4 can be increased or decreased. This aims to allow users to easily increase or decrease the number of panels 4 as needed, thereby enabling the tray panel structure to meet different size requirements and load-bearing needs. Simultaneously, users do not need to store multiple sizes of tray panels 4, thus reducing inventory types and space usage. On the other hand, the second fixing plate 5 confines the panel 4 within the mounting groove 3, reducing the risk of the panel 4 sliding out of the mounting groove 3 and ensuring the stability of the panel 4 connection. Furthermore, if a component (such as the panel 4, the first fixing plate 1, the support plate 2, or the second fixing plate 5) is damaged, only the damaged component needs to be replaced, thus reducing maintenance costs and resource waste.

[0039] Example 2: Based on Example 1 above, in this example, as follows... Figure 3 Combination Figure 4 As shown, the panel 4 includes a first horizontal plate 41 and a horizontally extending plate 42; there are two horizontally extending plates 42, and the two horizontally extending plates 42 are symmetrically arranged on both sides of the first horizontal plate 41; the horizontally extending plate 42 includes an arc-shaped plate element 421 and a groove-shaped plate element 422; the groove openings of the arc-shaped plate element 421 and the groove openings of the groove-shaped plate element 422 both face upwards; one side of the groove-shaped plate element 422 is connected to the first horizontal plate 41; the arc-shaped plate element 421 is connected to the other side of the groove-shaped plate element 422.

[0040] For example, in implementation, the panel 4 described above includes a first transverse plate 41 and a transversely extending plate 42.

[0041] There are two transverse extension plates 42, which are symmetrically distributed below the first transverse plate 41. The two transverse extension plates 42 are respectively connected to both sides of the first transverse plate 41 by welding, screwing or integral molding.

[0042] The transversely extending plate 42 includes an arc-shaped plate element 421 and a grooved plate element 422. The grooves of both the arc-shaped plate element 421 and the grooved plate element 422 face upwards. One side of the grooved plate element 422 is connected to the side wall of the first transverse plate 41 by means of welding, screwing, or integral molding, while the arc-shaped plate element 421 is connected to the side of the grooved plate element 422 away from the first transverse plate 41 by means of welding, screwing, or integral molding.

[0043] During use, the arc-shaped plate element 421, the grooved plate element 422, and the first transverse plate 41 are assembled to form a panel 4, and both ends of the panel 4 are inserted into two mounting slots 3 respectively. This allows the upper surfaces of the arc-shaped plate element 421, the grooved plate element 422, and the first transverse plate 41 to collectively form a load-bearing surface for supporting goods. On one hand, by introducing the arc-shaped plate element 421 and the grooved plate element 422, it is hoped that the overall rigidity and load-bearing capacity of the panel 4 will be increased, thereby enabling the pallet to withstand heavier or more complex loads. On the other hand, the upward-facing slots of the arc-shaped plate element 421 and the grooved plate element 422 form continuous grooves, which provide better support for specific types of goods. Especially for items requiring additional stability (such as cylindrical or irregularly shaped goods), the grooves can be used for positioning, effectively reducing the risk of goods shifting during transportation and ensuring safe transport.

[0044] Example 3: Based on Example 2 above, in this example, as follows... Figure 6 , Figure 7 or Figure 8 As shown, the cross-sectional area of ​​the grooved plate element 422 gradually decreases along the direction from the groove opening of the grooved plate element 422 to the bottom of the groove.

[0045] For example, in implementation, the cross-sectional area of ​​the aforementioned channel-shaped plate element 422 gradually decreases along the direction from the opening to the bottom of the channel. That is, the channel walls of the channel element 422 gradually approach each other along the direction from the opening to the bottom, forming a conical or trapezoidal reinforcing rib structure between the channel walls. On the one hand, this results in the channel element 422 having a higher moment of inertia than a rectangular section, aiming to more effectively reduce the risk of bending deformation. On the other hand, while meeting strength requirements, the gradually changing section uses less material than a rectangular section of uniform thickness. This aims to achieve lightweighting, thereby reducing the pallet's self-weight and increasing the effective load.

[0046] Example 4: Based on Example 2 above, in this example, as... Figure 6 , Figure 7 or Figure 8 As shown, the arc-shaped plate element 421 includes a first horizontal segment 4211 and an arc-shaped segment 4212; the number of the first horizontal segments 4211 is set to a plurality of them, and the plurality of the first horizontal segments 4211 are arranged at intervals along the first transverse plate 41 toward the grooved plate element 422, and the first horizontal segment 4211 closest to the first transverse plate 41 is connected to the first transverse plate 41; wherein, any two adjacent first horizontal segments 4211 are connected by the arc-shaped segment 4212.

[0047] For example, in the implementation process, the above-mentioned arc-shaped plate element 421 includes a first horizontal segment 4211 and an arc-shaped segment 4212.

[0048] The number of first horizontal segments 4211 is set to N, where N is an integer greater than or equal to 2. The N first horizontal segments 4211 are arranged at intervals along the direction from the first transverse plate 41 toward the channel-shaped plate element 422. Among them, the first horizontal segment 4211 closest to the channel-shaped plate element 422 is denoted as the first first horizontal segment 4211, and the first first horizontal segment 4211 is connected to the side of the channel-shaped plate element 422 away from the first transverse plate 41 by means of welding, screwing, or integral molding.

[0049] The number of arc-shaped segments 4212 is set to N-1, and these N-1 arc-shaped segments 4212 are evenly distributed among the N first horizontal segments 4211. That is, an arc-shaped segment 4212 is evenly distributed between any two adjacent first horizontal segments 4211. The arc-shaped segments 4212 are connected to the adjacent first horizontal segments 4211 by means of welding, screwing, or integral molding.

[0050] For example, when the number N of the first horizontal segment 4211 is equal to 2, the number of arc segments 4212 is 1. This forms a shape like... Figure 6The arc-shaped plate element 421 is shown. When the number N of the first horizontal segments 4211 is equal to 3, the number of arc segments 4212 is 2. This forms a shape as shown... Figure 7 The arc-shaped plate element 421 is shown. When the number N of the first horizontal segments 4211 is equal to 4, the number of arc segments 4212 is 3. This forms a shape as shown... Figure 8 The arc-shaped plate element 421 is shown.

[0051] In specific implementation, the aforementioned panel 4 can have multiple configurations, such as N=1, N=2, and N=3, and the panel structure can include one or more of these configurations. On one hand, this aims to create panels 4 of different widths, allowing users to select and combine panels 4 of varying widths to meet different pallet size and load requirements. On the other hand, a wavy surface texture can be formed on the upper surface of the panel 4. This is intended to significantly increase the sliding friction between the upper surface of the panel 4 and the bottom of the goods, thereby further reducing the risk of goods sliding.

[0052] Example 5: Based on Example 4 above, in this example, as... Figure 4 Combination Figure 6 , Figure 7 or Figure 8 As shown, the panel 4 also includes a first longitudinal plate 43; the first longitudinal plate 43 is connected to the first horizontal segment 4211 of the plurality of first horizontal segments 4211 that is away from the first transverse plate 41.

[0053] For example, in implementation, the panel 4 further includes a first longitudinal plate 43. There are two first longitudinal plates 43, symmetrically distributed on both sides of the first transverse plate 41. The first longitudinal plates 43 are connected to the lower side of the transverse extension plate 42 away from the first transverse plate 41 by welding, screwing, or integral molding. That is, the first longitudinal plate 43 is connected to the lower side of the N first horizontal segments 4211 away from the first transverse plate 41 by welding, screwing, or integral molding, and is located on the side of the first horizontal segment 4211 away from the first transverse plate 41. In other words, the first longitudinal plate 43 is connected to the lower side of the Nth first horizontal segment 4211 away from the first transverse plate 41.

[0054] During implementation, after the panel 4 is inserted into the mounting groove 3, the end of the first longitudinal plate 43 away from the first horizontal section 4211 (i.e., the lower end face of the first longitudinal plate 43) is attached to one wall of the mounting groove 3, while the upper surface of the first horizontal section 4211, the upper surface of the first transverse plate 41, and the upper surface of the grooved plate element 422 are all attached to the other wall of the mounting groove 3. The first longitudinal plate 43 acts as a reinforcing beam, significantly improving the bending stiffness of the panel 4 in the length direction and the torsional stiffness of the entire pallet. This aims to reduce the risk of torsional deformation of the pallet during forklift handling, thereby enhancing the overall stiffness and torsional performance of the panel 4.

[0055] Example 6: Based on Example 5 above, in this example, as... Figure 6 , Figure 7 or Figure 8 As shown, the first longitudinal plate 43 includes a longitudinal plate element 431 and a second horizontal segment 432; the upper end of the longitudinal plate element 431 is connected to the first horizontal segment 4211 away from the first transverse plate 41 among the plurality of first horizontal segments 4211; the second horizontal segment 432 is connected to the side of the lower end of the longitudinal plate element 431 close to the first transverse plate 41.

[0056] For example, in implementation, the first longitudinal plate 43 includes a longitudinal plate element 431 and a second horizontal segment 432.

[0057] The upper end of the longitudinal plate element 431 is connected to the lower side of the Nth horizontal segment away from the first transverse plate 41 by means of welding, screwing, or integral molding.

[0058] The second horizontal segment 432 is connected to the lower end of the longitudinal plate element 431 by means of welding, screwing, or integral molding, and the second horizontal segment 432 is located on the side of the longitudinal plate element 431 closer to the first transverse plate 41. That is to say, the second horizontal segment 432 extends in the direction closer to the first transverse plate 41.

[0059] During implementation, after panel 4 is inserted into mounting groove 3, the second horizontal segment 432 is attached to one wall of mounting groove 3, and the upper surfaces of the first horizontal segment 4211, the first transverse plate 41, and the grooved plate element 422 are all attached to the other wall of mounting groove 3. The longitudinal plate element 431 is supported between the second horizontal segment 432 and the first horizontal segment 4211. Under the action of vertical shear force (such as stacking pressure), the second horizontal segment 432 provides an additional load-bearing surface to share the pressure from the first horizontal segment 4211. This is intended to further improve the bending stiffness of panel 4 in the length direction and the torsional stiffness of the entire pallet, thereby reducing the risk of torsion deformation of the pallet during forklift handling and improving the overall stiffness and torsional performance of panel 4.

[0060] In a preferred embodiment, the ends of the second horizontal segments 432 that are close to each other are bent upwards.

[0061] Example 7: Based on Example 1 above, in this example, as follows... Figure 5 As shown, the second fixing plate 5 includes a second transverse plate 51 and a second longitudinal plate 52; the second longitudinal plate 52 is connected to the lower part of the second transverse plate 51; there are two second longitudinal plates 52, and the two second longitudinal plates 52 are arranged opposite to each other on both sides of the second transverse plate 51.

[0062] For example, in the implementation process, the second fixing plate 5 includes a second transverse plate 51 and a second longitudinal plate 52.

[0063] The second longitudinal plate 52 is connected to the lower surface of the second transverse plate 51 by means of welding, screwing, or integral molding. There are two second longitudinal plates 52, which are stacked and distributed on both sides of the lower surface of the second transverse plate 51.

[0064] During implementation, after the second fixing plate 5 is inserted into the mounting groove 3, the upper surface of the second transverse plate 51 is attached to one wall of the mounting groove 3, and the lower end surface of the second longitudinal plate 52 is attached to the other wall of the mounting groove 3. This is intended to effectively enhance the rigidity and torsional resistance of the pallet end, thereby reducing the risk of the pallet end twisting or deforming during handling.

[0065] Example 8: Based on Example 7 above, in this example, as... Figure 5 As shown, the second fixing plate 5 also includes a third transverse plate 53; the third transverse plate 53 is connected to the lower end of the second longitudinal plate 52, and the third transverse plate 53 is located directly below the second transverse plate 51.

[0066] For example, in the implementation process, the second fixing plate 5 also includes a third transverse plate 53.

[0067] The third transverse plate 53 is connected to the lower surface of the second longitudinal plate 52 by means of welding, screwing, or integral molding, and the third transverse plate 53 is located on the side of the second longitudinal plate 52 closer to the second transverse plate 51. That is to say, the third transverse plate 53 extends towards the second transverse plate 51.

[0068] During implementation, after the second fixing plate 5 is inserted into the mounting groove 3, the upper surface of the second transverse plate 51 is attached to one wall of the mounting groove 3, and the lower surface of the third transverse plate 53 is attached to the other wall of the mounting groove 3. The second longitudinal plate 52 is supported between the second transverse plate 51 and the third transverse plate 53. Under the action of vertical shear force (such as stacking pressure), the third transverse plate 53 provides an additional load-bearing surface to share the pressure from the second transverse plate 51. This is intended to further improve the bending stiffness of the second fixing plate 5 in the length direction and the torsional stiffness of the entire pallet, thereby reducing the risk of torsional deformation of the pallet during forklift handling and improving the overall stiffness and torsional performance of the pallet panel structure.

[0069] In a preferred embodiment, the structure of the first fixing plate 1 is the same as that of the second fixing plate 5.

[0070] Example 9: This example provides a tray, such as Figure 9 As shown, the tray includes a tray panel structure as described in any of Embodiments 1-8.

[0071] For example, in implementation, the tray includes a tray panel structure as shown in any of the embodiments 1-8 above.

[0072] On the one hand, when the size of the tray panel 4 needs to be adjusted, the second fixing plate 5 can be removed, and the number of panels 4 can be increased or decreased. This aims to allow users to easily increase or decrease the number of panels 4 as needed, thereby enabling the tray panel structure to meet different size requirements and load-bearing needs. Simultaneously, users do not need to store multiple sizes of tray panels 4, thus reducing inventory types and space usage. On the other hand, the second fixing plate 5 confines the panel 4 within the mounting groove 3, reducing the risk of the panel 4 sliding out of the mounting groove 3 and ensuring the stability of the panel 4 connection. Furthermore, if a component (such as the panel 4, the first fixing plate 1, the support plate 2, or the second fixing plate 5) is damaged, only the damaged component needs to be replaced, thus reducing maintenance costs and resource waste.

More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims.
