[0039] In order to solve the problem that the pallet is easily damaged by collision or impact during use, an embodiment of the present disclosure provides a pallet foot and a pallet with a protective structure, which is described in detail below with reference to the accompanying drawings.

[0040] Figure 1 FIG. 1 is a schematic diagram of a three-dimensional structure of a pallet foot with a protective structure according to an embodiment of the present disclosure. Figure 1 The specific embodiment of the present disclosure provides a pallet foot 1 with a protective structure, which is suitable for being arranged at the corner of a load-bearing plate of a pallet to support the load-bearing plate. The pallet foot 1 with a protective structure comprises: a first surface 11, a second surface 12 opposite to the first surface 11, and a side surface 13 arranged between the first surface 11 and the second surface 12. The first surface 11 of the pallet foot 1 with a protective structure is suitable for contacting with the lower surface of the load-bearing plate to support the load-bearing plate.

[0041] The pallet foot 1 with a protective structure also includes: a first protective edge structure 14, which is arranged on a partial edge of the first surface 11 and protrudes from the first surface 11, and is suitable for being located on the outside of the corners of the supporting plate to protect the corners of the supporting plate when the first surface 11 contacts the lower surface of the supporting plate.

[0042] In some specific embodiments, the first protective edge structure 14 is disposed at the corners of the first surface 11 .

[0043] In some specific embodiments, the shape of the first protective edge structure 14 matches the shape of the corner of the carrier board located inside the first protective edge structure 14, so that the corner of the carrier board can be more closely protected. In other words, the shape of the first protective edge structure 14 can be designed according to the shape of the corner of the carrier board. In some specific embodiments, the first protective edge structure 14 is in an arc shape or a right angle shape, so as to be used for correspondingly protecting the carrier board with an arc-shaped corner or a right angle corner; in some specific embodiments, the curvature of the arc-shaped first protective edge structure 14 is consistent with the curvature of the arc-shaped corner of the carrier board.

[0044] In order to better realize the protective effect of the first protective edge structure 14 on the corners of the load-bearing plate, the mechanical strength and impact resistance of the first protective edge structure 14 can be improved by setting reinforcing ribs. In some specific embodiments, the first protective edge structure 14 includes: an inner wall 141 and an outer wall 142, and a reinforcing rib 143 arranged between the inner wall 141 and the outer wall 142, and the reinforcing rib 143 increases the overall mechanical strength of the first protective edge structure 14. In some specific embodiments, there are multiple reinforcing ribs 143, and the multiple reinforcing ribs 143 are evenly distributed between the inner wall 141 and the outer wall 142. In some specific embodiments, the wall thickness of the outer wall 142 is greater than the wall thickness of the inner wall 141, so that the first protective edge structure 14 has better structural strength, better absorbs and disperses the impact force when facing external impact, and is not easy to deform or break. In some specific embodiments, the wall thickness of the reinforcing rib 143 is 2-3 mm, for example, 2 mm, 2.1 mm, 2.3 mm, 2.5 mm, 2.7 mm, 2.9 mm or 3 mm, etc.; the wall thickness of the inner wall 141 is 2-4 mm, for example, 2 mm, 2.1 mm, 2.3 mm, 2.5 mm, 2.7 mm, 2.9 mm, 3 mm, 3.1 mm, 3.3 mm, 3.5 mm, 3.7 mm, 3.9 mm or 4 mm, etc.; the wall thickness of the outer wall 142 is 3-4 mm, for example, 3 mm, 3.1 mm, 3.3 mm, 3.5 mm, 3.7 mm, 3.9 mm or 4 mm, etc. In some specific embodiments, the wall thickness of the outer wall 142 is greater than the wall thickness of the reinforcing rib 143, and the wall thickness of the reinforcing rib 143 is greater than the wall thickness of the inner wall 141, and the first protective edge structure 14 has good impact resistance and structural strength.

[0045] In some specific embodiments of the pallet foot with a protective structure disclosed herein, the second surface 12 of the pallet foot 1 with a protective structure is suitable for contacting the ground or a bottom plate, and the ground or the bottom plate supports the pallet foot 1 from the second surface 12 .

[0046] In some specific embodiments, the pallet foot 1 with a protective structure also includes: a second protective edge structure 15, which is arranged on a partial edge of the second surface 12 and protrudes from the second surface 12, and is suitable for being located on the outside of the corners of the bottom plate to protect the corners of the bottom plate when the second surface 12 contacts the upper surface of the bottom plate.

[0047] In some specific embodiments, the second protective edge structure 15 is disposed at the corners of the second surface 12 .

[0048] In some specific embodiments, the shape of the second protective edge structure 15 matches the shape of the corner of the bottom plate located inside the second protective edge structure 15, so that the corner of the bottom plate can be protected more closely. In other words, the shape of the second protective edge structure 15 can be designed according to the shape of the corner of the bottom plate. In some specific embodiments, the second protective edge structure 15 is in an arc shape or a right angle shape, so as to be used to protect the bottom plate with an arc-shaped corner or a right angle corner; in some specific embodiments, the curvature of the arc-shaped second protective edge structure 15 is consistent with the curvature of the arc-shaped corner of the bottom plate.

[0049] In order to better realize the protective effect of the second protective edge structure 15 on the corners of the load-bearing plate, the mechanical strength and impact resistance of the second protective edge structure 15 can be improved by setting reinforcing ribs; in some specific embodiments, the setting method of the reinforcing ribs is the same as the setting method of the reinforcing ribs in the first protective edge structure 14, which will not be repeated here.

[0050] In the specific embodiments of the pallet foot with a protective structure disclosed in the present invention, in some specific embodiments, the pallet foot 1 also includes: a mounting groove 16, which is arranged on the side 13 of the pallet foot 1 facing outward, and the mounting groove 16 is suitable for installing a protective rod, which extends in the vertical direction to further enhance the protection of the load-bearing plate on the basis of the protection of the first protective edge 14, and at the same time protect the items carried by the load-bearing plate in the vertical direction. A supporting structure and another load-bearing structure can also be installed on the protective rod, thereby realizing multi-layer loading of items on the pallet.

[0051] In some specific embodiments, two or more installation grooves 16 are provided on the side 13, thereby providing two or more installation positions for the protective rod, thereby enhancing the fixing strength of the protective rod and the pallet foot 1 with a protective structure after installation, which is beneficial to impact and collision resistance and enhances the protective effect of the load-bearing plate and the items carried by the load-bearing plate.

[0052] In some specific embodiments, the mounting groove 16 has an opening on the side 13 , and the opening is a rectangle with a length of 80 to 100 mm and a width of 10 to 20 mm.

[0053] The pallet foot with a protective structure of the specific embodiments of the present disclosure, in some specific embodiments, the structure between the first surface 11, the second surface 12 and the side of the pallet foot 1 is a hollow structure. The hollow structure reduces the overall weight of the pallet foot 1, reduces the amount of manufacturing materials for the pallet foot 1, and saves the manufacturing cost of the pallet foot 1.

[0054] Under the condition of ensuring the structural strength of the first protective edge structure 14, the hollow structure can have a variety of designs. In some specific embodiments, the hollow structure includes: a first hollow portion 17 and a second hollow portion (not shown in the figure), and a solid portion located between the first hollow portion 17 and the second hollow portion. The solid portion is beneficial to ensuring the overall structural strength of the pallet foot 1. In some specific embodiments, the thickness of the solid portion is 2 to 4 mm, for example 2 mm, 2.1 mm, 2.3 mm, 2.5 mm, 2.7 mm, 2.9 mm, 3 mm, 3.1 mm, 3.3 mm, 3.5 mm, 3.7 mm, 3.9 mm or 4 mm.

[0055] In some specific embodiments, the volume of the hollow portion of the first hollow portion 17 is larger than the volume of the hollow portion of the second hollow portion, so that the second hollow portion below the first hollow portion 17 has more solid parts around it, thereby ensuring the overall structural strength of the pallet foot 1.

[0056] In some specific embodiments, the first hollow portion 17 is extended from the solid portion to the first surface 11 of the pallet foot 1; in some specific embodiments, the hollow portion of the first hollow portion 17 is composed of a cavity extending from the solid portion to the first surface 11, and an opening is formed on the first surface 11, the number of the cavities is more than one, and solid cavity walls are between adjacent cavities.

[0057] In some specific embodiments, the second hollow portion is extended from the solid portion to the second surface 12 of the pallet foot 1; in some specific embodiments, the hollow portion of the second hollow portion is composed of a cavity extending from the solid portion to the second surface 12, and an opening is formed on the second surface 12, the number of the cavities is more than one, and solid cavity walls are between adjacent cavities.

[0058] In some specific embodiments, the first hollow portion 17 includes five cavities extending from the solid portion to the first surface 11 , and the second hollow portion includes four cavities extending from the solid portion to the second surface.

[0059] In the specific embodiments of the pallet foot with a protective structure disclosed in the present invention, in some specific embodiments, the material of the pallet foot 1 is thermoplastic plastic or modified thermoplastic plastic; in some specific embodiments, the material of the pallet foot 1 is polypropylene or modified polypropylene. The modified type of the thermoplastic plastic modified material can be modified accordingly according to the application requirements, including but not limited to toughening modification, flame retardant modification, reinforcement modification, etc., and the modified additives and modification methods are not limited here.

[0060] In some specific embodiments, the material of the reinforcing rib is a thermoplastic plastic that is the same as or different from the material of the first protective edge structure 14 .

[0061] A specific embodiment of the present disclosure further provides a pallet suitable for placing articles, wherein the pallet comprises a load-bearing plate and a pallet foot with a protective structure as described in any of the above specific embodiments.

[0062] Figure 2 FIG. 2 shows a three-dimensional structural schematic diagram of a tray according to an embodiment of the present disclosure. Figure 2 The pallet includes: a load-bearing board 2 for placing articles; and a pallet foot 1 with a protective structure. The pallet foot 1 with a protective structure is arranged at the corner of the load-bearing board 2, the first surface of the pallet foot 1 with a protective structure contacts and is fixed to the lower surface of the load-bearing board 2, and the first protective edge structure 14 of the pallet foot 1 with a protective structure is located outside the corner 21 of the load-bearing board 2 to protect the corner 21 of the load-bearing board 2.

[0063] The pallet foot 1 with a protective structure is the same as the pallet foot 1 with a protective structure described in any of the above specific embodiments, and will not be described in detail herein.

[0064] In the pallet of the specific embodiments of the present disclosure, in some specific embodiments, the lower surface of the supporting plate 2 is rectangular or rounded rectangular, and the four corners 21 of the supporting plate 2 are respectively provided with the pallet feet 1 with the protective structure, that is, the four pallet feet 1 with the protective structure respectively support the supporting plate 2 at the four corners 21 of the supporting plate 2 and protect the corners 21.

[0065] In some specific embodiments, the shape of the first protective edge structure 14 of the pallet foot 1 with a protective structure matches the shape of the corner 21 of the load-bearing plate 2 located on the inner side of the first protective edge structure 14, so that the first protective edge structure 14 and the corner 21 of the load-bearing plate 2 can be completely fitted and fixed to each other. The load-bearing plate 2 supports the first protective edge structure 14, which helps to increase the structural strength of the first protective edge structure 14, thereby helping to protect the corner 21 of the load-bearing plate 2 from being damaged in collision or impact. In some specific embodiments, the load-bearing plate 2 is rectangular, and the shape of the first protective edge structure 14 is right-angled; in some specific embodiments, the load-bearing plate 2 is a rounded rectangle, and the shape of the first protective edge structure 14 is arc-shaped, and the curvature of the arc of the first protective edge structure 14 is consistent with the curvature of the rounded corner of the corner 21 of the load-bearing plate 2.

[0066] In some specific embodiments, the height of the first protective edge structure 14 is consistent with the thickness of the supporting plate 2, thereby preventing the portion of the supporting plate 2 that is higher than the first protective edge structure 14 from being unprotected due to the thickness of the supporting plate 2 being greater than the height of the first protective edge structure 14, and also preventing the first protective edge structure 14 from protruding from the supporting plate 2, thereby causing the objects carried on the supporting plate 2 to collide with the first protective edge structure 14 and obstruct the objects or even cause damage to the objects or the first protective edge structure 14.

[0067] In some specific embodiments, the supporting plate 2 is a rectangular structure with a length of 800 to 1400 mm, a width of 800 to 1400 mm, and a thickness of 10 to 30 mm, or a quasi-rectangular structure with rounded rectangular upper and lower surfaces. The corners 21 of the supporting plate 2 are in a right-angle shape or a rounded shape that matches the first protective edge structure 14; the height of the first protective edge structure 14 is 10 to 30 mm and is consistent with the thickness of the supporting plate 2.

[0068] In order to further enhance the support strength of the load-bearing plate 2 to carry items of a certain weight, the pallet of the specific embodiment of the present disclosure further comprises: a support pallet foot 3, which is arranged in the area other than the corner 21 of the load-bearing plate 2 to support the load-bearing plate 2, and the support pallet foot 3 is in contact with and fixed to the lower surface of the load-bearing plate 2. The support pallet foot 3 and the pallet foot 1 with a protective structure are both in contact with and fixed to the lower surface of the load-bearing plate 2, and together support the load-bearing plate 2.

[0069] For a load-bearing board 2 whose upper and lower surfaces are both rectangular or rounded rectangular, four pallet feet 1 with protective structures are arranged at four boundaries 21 of the load-bearing board 2 to protect the boundaries 21. The number and distribution of the supporting pallet feet 3 can be designed according to the size of the load-bearing board 2 and the weight of the items that the load-bearing board 2 actually needs to carry. In order to make the pallet as a whole have good and uniform structural strength, in some specific embodiments, the supporting pallet feet 3 and the pallet feet 1 with protective structures are evenly distributed on the lower surface of the load-bearing board 2 to evenly support the load-bearing board 2.

[0070] In some specific implementations, the number of the tray supporting feet 3 is four, which are respectively disposed at the midpoints of the four rectangular sides of the lower surface of the carrying plate 2 .

[0071] In some specific embodiments, the number of supporting pallet feet 3 is 5, wherein 4 supporting pallet feet 3 are respectively arranged at the midpoints of the 4 rectangular sides of the lower surface of the loading plate 2, and 1 supporting pallet foot 3 is arranged at the rectangular center position of the lower surface of the loading plate 2, that is, the 5 supporting pallet feet 3 and the 4 pallet feet 1 with protective structures form three groups of parallel and basically equidistant pallet feet to support the loading plate 2.

[0072] In some specific embodiments of the pallet disclosed herein, the pallet foot 1 with the protective structure and the supporting pallet foot 3 are directly placed on the ground or other supporting planes.

[0073] In order to have better supporting strength and structural strength, in some specific embodiments, the pallet also includes a bottom plate 4, which is arranged below the supporting plate 2, and the pallet foot 1 with a protective structure is arranged between the supporting plate 2 and the bottom plate 4, and the bottom plate 4 is in contact with the second surface 12 of the pallet foot 1 with a protective structure and is fixed to each other.

[0074] In some specific embodiments, the pallet foot 1 with a protective structure includes: a second protective edge structure 15, which is provided at a portion of the edge of the second surface 12 and protrudes from the second surface 12, and is suitable for being located outside the corner of the bottom plate 4 when the second surface 12 contacts the upper surface of the bottom plate 4 to protect the corner of the bottom plate 4. The second protective edge structure 15 is the same as that described in any of the above specific embodiments, and will not be repeated here. That is, the first protective structure 14 contacts the corner 21 of the load-bearing plate 2 from the outside and is fixed to each other, and the second protective structure 15 contacts the corner of the bottom plate 4 from the outside and is fixed to each other, thereby realizing the protection of the corner of the load-bearing plate 2 and the corner of the bottom plate 4.

[0075] In some specific embodiments, the shape and size of the bottom plate 4 are consistent with the shape and size of the bottom plate 4 , thereby forming a more stable supporting structure.

[0076] In some specific embodiments, the base plate 4 includes three independent support strips that are arranged parallel to each other. The support strip in the middle is in contact with and fixed to three supporting pallet feet 3 respectively, and the two support strips on both sides are in contact with and fixed to two pallet feet 1 with protective structures and one supporting pallet foot 3 respectively. There is a gap between each support strip. Compared with a whole plate, the independently arranged support strips save more materials of the base plate 4, thereby reducing the manufacturing cost of the pallet.

[0081] In some specific embodiments, the carrier plate 2 is rectangular or rounded rectangular, and the pallet feet 1 with protective structures are respectively provided at the four corners of the carrier plate 2, and the four protective rods 18 are respectively fixed to the four pallet feet 1 with protective structures, and the protective rods 18 include mounting portions, which are arranged at the tops of the protective rods 18; the pallet also includes: two supporting cross bars 19 arranged in an X-shape, and the two ends of each supporting cross bar 19 are respectively connected and fixed to the mounting portions of the two protective rods 18 located at the diagonal positions of the carrier plate 2, and are perpendicular to the protective rods 18; the loading tray arranged on the two supporting cross bars 19 is suitable for placing articles. That is, the first layer of articles is carried by the carrier plate 2, and the second layer of articles is carried by the loading tray. While the protective rods 18 enhance the protection of the carrier plate 2 and the articles, the use efficiency of the space is improved. In addition, based on the fact that the bearing strength of the carrier plate 2 is greater than that of the loading tray, the carrier plate 2 is suitable for carrying heavier articles, and the loading tray is suitable for carrying lighter articles, so as to ensure the stability of the overall structure of the pallet.

[0082] In the specific embodiments of the pallet foot with a protective structure disclosed herein, in some specific embodiments, the load-bearing plate 2 and the pallet foot with a protective structure 1 and the supporting pallet foot 3 are fixed to each other by bonding.

[0083] In the specific embodiments of the pallet foot with a protective structure disclosed in the present invention, in some specific embodiments, the load-bearing plate 2 is made of continuous fiber reinforced thermoplastic prepreg and honeycomb thermoplastic. The addition of continuous fibers increases the mechanical strength of the load-bearing plate 2, and the honeycomb structure makes the load-bearing plate 2 relatively light, thereby giving the load-bearing plate 2 the characteristics of light weight and high mechanical properties. Compared with the load-bearing plate made of traditional plastic or wood, it has better load-bearing performance for articles; in some specific embodiments, the material of the pallet foot 1 with a protective structure is thermoplastic or modified thermoplastic. In some specific embodiments, the material of the supporting pallet foot 3 is thermoplastic or modified thermoplastic. In some specific embodiments, the material of the bottom plate 4 is thermoplastic or modified thermoplastic, or the material of the bottom plate 4 is made of continuous fiber reinforced thermoplastic prepreg and honeycomb thermoplastic. It should be noted that the thermoplastic plastics in the materials of the load-bearing plate 2, the bottom plate 4, the pallet foot 1 with a protective structure and the supporting pallet foot 3 can be the same or different thermoplastic plastics. For thermoplastic modified materials, the thermoplastic plastics can be prepared by corresponding modification of the thermoplastic plastics according to different requirements. The modified additives and modification methods are not limited here.

[0084] In some specific embodiments, the material of the supporting plate 2 is continuous fiber reinforced thermoplastic plastic, the material of the pallet foot 1 with a protective structure is thermoplastic plastic, and the supporting plate 2 and the pallet foot 1 with a protective structure are fixed by hot melt welding; further, the material of the supporting pallet foot 3 is also thermoplastic plastic, and the supporting plate 2 and the pallet foot 1 with a protective structure and the supporting pallet foot 3 are fixed by hot melt welding, so that the supporting plate 2 and the pallet foot 1 with a protective structure and the supporting pallet foot 3 all have good interface strength and bonding force, thereby improving the overall mechanical strength and structural stability of the pallet; further, the material of the bottom plate 4 is thermoplastic plastic, or thermoplastic modified material, or is made of continuous fiber reinforced thermoplastic plastic prepreg and honeycomb thermoplastic plastic, and the bottom plate 4 and the supporting plate 2 and the pallet foot 1 with a protective structure and the supporting pallet foot 3 are all fixed by hot melt welding, and the hot melt welding fixation makes the supporting pallet foot 3 and the pallet foot 1 have good interface strength and bonding force with the supporting pallet foot 3 and the bottom plate 4, so that the pallet as a whole has good mechanical strength and stability.

[0085] The above is only an exemplary embodiment used to illustrate the principle of the present disclosure, and is not intended to limit the scope of protection of the present disclosure. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present disclosure, and these modifications and improvements are also within the scope of protection of the present disclosure.
