[0083] Reference will now be made to Figures 1 to 9 Exemplary embodiments according to the present application will be described in more detail.

[0084] First preferred embodiment

[0085] Reference will first be made to Figure 1 , Figure 2 , Figure 3 and Figure 4 The tray 100 of the first preferred embodiment of the present application is generally composed of a base assembly, a load-bearing assembly, and a support assembly. The base assembly is used to be placed on the ground. The load-bearing assembly is located above the base assembly, preferably spaced apart, for carrying goods located thereon. The support assembly is located between the two, bridging the gap, to support the load-bearing assembly.

[0086] Specifically, the tray 100 is preferably configured as a rectangle. More preferably, the tray 100 is configured as a square. The base assembly includes a bottom frame 150, which is arranged along the circumference of the tray 100. Alternatively, the bottom frame 150 is also configured as a square. The bottom frame 150 can be made by splicing and welding pipes, such as steel pipes. Preferably, the bottom frame 150 is made by splicing or welding four pipes, the ends of which are configured as male and female sleeve designs for easy insertion. Preferably, at least one set of opposite pipes of the bottom frame 150 is provided with a shovel. For example, the bottom of at least one set of opposite pipes of the bottom frame 150 is partially concave, or the bottom of the above-mentioned pipes is partially flattened, to leave space for the passage of the forks of a forklift.

[0087] The support assembly includes a first load-bearing beam 101, a second load-bearing beam 102, and four second supports 140. The first load-bearing beam 101 includes two load-bearing units 110 and a first support 130. Specifically, the two load-bearing units 110 are connected to the first support 130, and the first support 130 is located between the two load-bearing units 110.

[0088] The second load-bearing beam 102 includes two abutting load-bearing units 110. The load-bearing unit 110, the first support 130, and the second support 140 are all configured as one-piece stampings. The size of the above-mentioned stampings can be changed by adjusting the mold.

[0089] The specific structure of the load-bearing unit 110 is shown in FIG. Figure 1 and Figure 2 , which includes a main beam portion 111 and a support portion 112. The main beam portion 111 extends along the length direction or width direction of the pallet 100. The support portion 112 is located at the end of the main beam portion 111 and is constructed as an inverted trapezoid that is concave downward to contact the base assembly, or in other words, to contact the bottom frame 150. Exemplarily, the inverted trapezoid is preferably a right-angled trapezoid. As a result, the inverted trapezoidal support portion 112 can achieve a vibration reduction effect and effectively alleviate external force impact.

[0090] Specifically, the support portion 112 includes a hypotenuse portion 113, a base portion 114, and a side portion 115. The hypotenuse portion 113 is connected to the main beam portion 111. It extends obliquely downward from the end of the main beam portion 111. The hypotenuse portion 113 roughly constitutes the hypotenuse of an inverted trapezoid. The base portion 114 is connected to the hypotenuse portion 113 and is preferably arranged horizontally. In other words, the base portion 114 is horizontally arranged at the end of the hypotenuse portion 113 away from the main beam portion 111. The base portion 114 roughly constitutes the narrow bottom of the inverted trapezoid. The side portion 115 is connected to the base portion 114 and is preferably arranged vertically. Thus, it can roughly constitute the straight side or height of the inverted trapezoid. In other words, the side portion 115 is vertically arranged at the end of the base portion 114 away from the hypotenuse portion 113. Among them, the main beam portion 111 and the hypotenuse portion 113 are constructed as corrugated plates to improve structural strength. In addition, the combination of the corrugated plate and the inverted right-angled trapezoid can more effectively reduce vibration while ensuring the overall structural strength.

[0091] Preferably, the bottom surface of the bottom edge portion 114 is provided with a first groove 116 and a second groove 117. Both the first groove 116 and the second groove 117 are recessed upward. Furthermore, the first groove 116 extends perpendicular to the main beam portion 111, while the second groove 117 is arranged orthogonally to the first groove 116. In other words, the second groove 117 extends perpendicularly to the first groove 116.

[0092] In this embodiment, the first load-bearing beam 101 and the second load-bearing beam 102 are arranged crosswise. Preferably, they are arranged orthogonally. In other words, the first load-bearing beam 101 and the second load-bearing beam 102 are perpendicular to each other. The second load-bearing beam 102 is located between the two load-bearing units 110 of the first load-bearing beam 101.

[0093] And, the first load-bearing beam 101 and the second load-bearing beam 102 are arranged on the bottom frame 150. Wherein, the first load-bearing beam 101 and the second load-bearing beam 102 are respectively perpendicular to two groups of opposite sides of the top frame 121. Specifically, the two support portions 112 of the first load-bearing beam 101 and the second load-bearing beam 102 are respectively located at the midpoints of the four sides of the square bottom frame 150. Thus, the four first grooves 116 on the four support portions 112 of the first load-bearing beam 101 and the second load-bearing beam 102 are respectively overlapped with one side of the bottom frame 150, and the pipe material of the bottom frame 150 can be embedded into the first groove 116. In this way, the stability and firmness of the installation can be improved.

[0094] The specific structure of the first support 130 can refer to Figure 1 and Figure 3 which are arranged at the middle part of the first load-bearing beam 101 and protrude downward from the main beam portion 111 to be connected to the base assembly.

[0095] More specifically, referring to Figure 3 , the first support 130 includes a first side wall 131, a second side wall 132, a bottom wall 133, a first connecting portion 134 and a second connecting portion 135. Wherein, the first side wall 131 and the second side wall 132 are arranged opposite to each other along the vertical direction. The bottom wall 133 is connected between the bottom end of the first side wall 131 and the bottom end of the second side wall 132. The first connecting portion 134 is horizontally arranged at the top end of the first side wall 131 and extends away from the second side wall 132. The second connecting portion 135 is horizontally arranged at the top end of the second side wall 132 and extends away from the first side wall 131. That is, the first connecting portion 134 and the second connecting portion 135 extend in opposite directions. Wherein, the first connecting portion 134 and the second connecting portion 135 are respectively used to connect, for example, weld or screw, with the two main beam portions 111 of the two load-bearing units 110 of the first load-bearing beam 101. Thus, when the first load-bearing beam 101 and the second load-bearing beam 102 are arranged in a cross manner, the second load-bearing beam 102 can pass between the first connecting portion 134 and the second connecting portion 135 of the first support 130, so as to avoid the interference between the corrugations on the first load-bearing beam 101 and the corrugations on the second load-bearing beam 102, and to make it difficult to be stably connected.

[0096] The third groove 136 and the fourth groove 137 are arranged on the bottom wall 133 and are recessed upward. And, the third groove 136 and the fourth groove 137 are arranged orthogonally or perpendicularly, so that the extending directions of the first load-bearing beam 101 and the second load-bearing beam 102 which are crossed are the same. In other words, the bottom wall 133 is roughly square, and the third groove 136 and the fourth groove 137 are respectively perpendicular to two groups of opposite sides of the bottom wall 133.

[0097] Preferably, the two second grooves 117 of the load-bearing unit 110 of the first load-bearing beam 101 are respectively collinear with the third groove 136 and the fourth groove 137.

[0098] Reference Figure 1 , four second supports 140 are respectively arranged at four corners of the bottom frame 150. The bottom of the second support 140 is connected with the bottom frame 150. The specific structure of the second support 140 refers to Figure 4 , which includes a first extension part 141, a second extension part 142 and a transition part 143. Among them, the first extension part 141 and the second extension part 142 are arranged perpendicular to each other, or in other words, perpendicular. The transition part 143 is connected between the first extension part 141 and the second extension part 142. And the first extension part 141 and the transition part 143, and the second extension part 142 and the transition part 143 are both smoothly transitioned. Therefore, the right angle design of the smooth transition can greatly improve the stability and relieve the impact.

[0099] In other words, the extension direction of the first extension part 141 and the second extension part 142 is parallel or overlapped with the two vertical edges of the bottom frame 150. Preferably, the outer side wall of the first extension part 141 and the second extension part 142 is constructed as a corrugated plate to further improve the bearing strength.

[0100] Continuing to refer to Figure 1 , the bearing assembly includes a top frame 121 and a panel (not shown). The shape of the top frame 121 is generally constructed as a rectangle, preferably a square. Or it is similar in shape to the bottom frame 150, also arranged along the circumference of the tray 100. Preferably, the top frame 121 has an embedded slot with an opening facing inward. Or in other words, each edge of the top frame 121 is provided with a U-shaped groove recessed in the horizontal direction and in the direction from the center of the tray 100 to the outside. The panel is inserted into the embedded slot, so that the four edges of the panel are surrounded by the top frame 121, thereby improving the firmness of the connection.

[0101] In this case, when installing the panel, the profile, such as light steel profile, can be used to first splice three edges of the top frame 121, and then splice the last edge after inserting the panel to complete the cladding. The panel can be constructed as a fiberglass composite panel, a bamboo-wood composite panel, a stamped steel plate or other types of composite panel materials, etc.

[0102] In this embodiment, the four second supports 140 are also located at the four corners of the top frame 121, i.e. the top surface of the second support 140 is connected with the bottom of the top frame 121. And the end of the bearing unit 110 is also connected with the top frame 121. Specifically, the top of the side edge part 115 of the support part 112 located at the end of the bearing unit 110 is connected to the top frame 121 to further support the bearing assembly. Preferably, the main beam part 111 of the bearing unit 110 can also be connected with the bottom surface of the panel to further improve the bearing strength. Exemplarily, the main beam part 111 can be welded or screwed to the panel.

[0103] The base assembly can further comprise a base plate 154, which is configured as a square plate substantially in accordance with the cross-sectional shape of the first support 130, to be connected to the bottom side of the first support 130. The base plate 154 can be configured as a plate-shaped profile, such as a light steel profile plate. Alternatively, the base plate 154 can be configured as a composite structure, for example, it can comprise a U-shaped base and a filler embedded in the U-shaped base.

[0104] Second preferred embodiment

[0105] Figure 5 A second preferred embodiment of the present application is shown. The second preferred embodiment of the present application is a variation of the first preferred embodiment. It differs from the first preferred embodiment in that the bottom surface of the first support 130 is not connected to the base plate 154, or in other words, the base assembly of the second preferred embodiment does not comprise a base plate 154.

[0106] In the present embodiment, the base assembly comprises, in addition to the bottom frame 150, a first reinforcing rib 152 and a second reinforcing rib 153. Both are preferably also made of a pipe material, such as stainless steel. Furthermore, the first reinforcing rib 152 and the second reinforcing rib 153 are arranged orthogonally, or in other words, perpendicularly. Moreover, the first reinforcing rib 152 and the second reinforcing rib 153 are arranged on the inner side of the bottom frame 150.

[0107] Here, the two ends of each of the first reinforcing rib 152 and the second reinforcing rib 153 are located at the midpoints of the four edges of the bottom frame 150, so that each of the first reinforcing rib 152 and the second reinforcing rib 153 is perpendicular to two pairs of opposite edges of the bottom frame 150. Furthermore, the first reinforcing rib 152 and the second reinforcing rib 153, which are made of a pipe material, are embedded in the third groove 136 and the fourth groove 137 of the bottom surface of the first support 130, respectively, and the first reinforcing rib 152 and the second reinforcing rib 153 are also embedded in the second groove 117 of the corresponding support portion 112.

[0108] Thus, the second preferred embodiment of the present application can be referred to as a cross-bottom tray 200.

[0109] Third preferred embodiment

[0110] Figure 6 A third preferred embodiment of the present application is shown. The third preferred embodiment of the present application is a variation of the second preferred embodiment. It differs from the second preferred embodiment in that only one first reinforcing rib 152 or only one second reinforcing rib 153 is provided, to obtain a sun-bottom tray 300.

[0111] Preferably, at least one set of opposing sides of the bottom frame 150 is bent toward the load-bearing assembly to form a shovel opening 151, thereby facilitating insertion by a ground bull or forklift. Specifically, a shovel opening 151 is provided between one of the second supports 140 and one of the support portions 112. That is, the edges of the tubular bottom frame 150 are bent upward to form a rectangular shovel opening 151.

[0112] Fourth preferred embodiment

[0113] Figure 7 FIG4 shows a fourth preferred embodiment of the present invention. The pallet 400 of the fourth preferred embodiment of the present invention is a variation of the second preferred embodiment. It differs from the second preferred embodiment in that only one first reinforcing rib 152 or only one second reinforcing rib 153 is provided, resulting in a Japanese-shaped bottom pallet 100.

[0114] Furthermore, the base assembly is preferably made of a plate-like profile. That is, the bottom frame 150 and the first reinforcing rib 152, or the bottom frame 150 and the second reinforcing rib 153, are both made of a plate-like profile, such as a light steel profile, to increase the contact area between the base assembly and the ground.

[0115] Fifth preferred embodiment

[0116] Figure 8 FIG2 shows a fifth preferred embodiment of the present invention. The fifth preferred embodiment of the present invention is a variation of the first preferred embodiment. It differs from the first preferred embodiment in that the support assembly includes three first load-bearing beams 101 and one reinforcement beam 118. Furthermore, the base assembly does not include a bottom frame 150, but instead consists of a plurality of base plates 154.

[0117] Specifically, the three first load-bearing beams 101 are arranged parallel and spaced apart from each other, with the spacing between two adjacent first load-bearing beams 101 being equal. The reinforcement beam 118 is arranged perpendicular to the three first load-bearing beams 101 and positioned above the three first supports 130. In other words, the reinforcement beam 118 can pass between the first connecting portion 134 and the second connecting portion 135 of each of the three first supports 130.

[0118] Furthermore, the bottom of each first support 130 and the bottom of each supporting portion 112 are connected to a base plate 154. In other words, in this embodiment, the base assembly includes nine base plates 154.

[0119] Thus, a nine-foot pallet 500 is formed. The reinforcing beam 118 and the base plate 154 are preferably made of a plate-shaped profile, such as a light steel profile plate.

[0120] Sixth preferred embodiment

[0121] Figure 9 A sixth preferred embodiment of the present application is shown. The sixth preferred embodiment of the present application is a variation of the fifth preferred embodiment. It differs from the fifth preferred embodiment in that the support assembly does not include the reinforcing beam 118. Also, the base assembly does not include the base plate 154.

[0122] In particular, the three first load-bearing beams 101 are parallel and spaced apart from each other, and the spacing between adjacent two first load-bearing beams 101 is equal.

[0123] In the present embodiment, the first load-bearing beams 101 can be different from other embodiments, for example, the two load-bearing units 110 of the first load-bearing beam 101 can also be abutted with each other.

[0124] The base assembly part includes three bottom beams 155, and the three bottom beams 155 are parallel and spaced apart from each other, and the spacing between adjacent two bottom beams 155 is equal. In particular, one of the three bottom beams 155 is connected at the bottom side of the three first supports 130. The other two bottom beams 155 are respectively connected at the two ends of the three first load-bearing beams 101. Or in other words, the other two bottom beams 155 are respectively connected at the bottom side of the support portions 112 located at the same side of the three first load-bearing beams 101.

[0125] Thus, the river-shaped bottom tray 600 is formed. The bottom beam 155 is preferably made of a plate-shaped profile, for example, a light steel profile plate.

[0126] According to the tray of the present application, different specifications of trays can be formed by using an integral stamping part and free combination of various profiles, and the structure is flexible and low in cost, and also has the advantages of strong universality, light weight, good strength, long service life, etc.
