[0065] FIG. 1A is a schematic diagram illustrating an exemplary cargo fixation device according to some embodiments of the present disclosure.
[0066] A cargo fixation device 10 may be configured to fix a cargo. In some embodiments, the cargo may have a small bottom area and a high height. In some embodiments, the cargo may be in any shape.
[0067] As shown in FIG. 1A, the cargo fixation device 10 may include a first pallet 100 configured to fix one or more cargoes.
[0068] In some embodiments, the first pallet 100 may include a support plate 110 and a support portion 120 disposed around the support plate 110. In some embodiments, the shape of the support plate 110 may be set in a rectangular shape so that it may be adapted as much as possible to fit the shape of a rectangular cargo (e.g., a packing box) to provide reliable support. In some embodiments, the shape of the support plate 110 may be set to other shapes, such as a circle, a triangle, a pentagon, a hexagon, or a shape that can match different cargoes to enhance the applicability of the first pallet 100.
[0069] As used herein, when the first pallet 100 is a rectangular structure, the height direction, the width direction, and the length direction of the first pallet 100 are perpendicular to each other, and the height direction may be a direction from a bottom to a top of the first pallet 100, the length direction may be a direction along a long side of the first pallet 100, and the width direction may be a direction along a short side of the first pallet 100. In addition, some embodiments of the present disclosure may define a top surface and a bottom surface of the first pallet 100. The top surface of the first pallet 100 is a surface located uppermost along the height direction, and the bottom surface of the first pallet 100 is a surface located lowermost along the height direction. When the first pallet 100 is carrying a cargo, the top surface faces the cargo and the bottom surface backs away from the cargo.
[0070] The support plate 110 has a support surface 111, and the support surface 111 is a contact surface of the support plate 110 with the cargo.
[0071] The first pallet 100 may be configured to switch between a first state and a second state. When the first pallet 100 is configured to be in the first state, the support surface 111 may be configured to be at the same level as the top surface of the support portion 120, and at this time, if the first pallet 100 is carrying a cargo, the support surface 111 and the support portion 120 may jointly bear the cargo. When the first pallet 100 is configured to be in the second state, the support surface 111 may be configured to be lower than the top surface of the support portion 120, and the support surface 111 and the support portion 120 may be configured to form an accommodation cavity. The cargo may be fixed in the accommodation cavity, the bottom surface of the accommodation cavity is the support surface 111, the support surface may bear the cargo, and side surfaces of the accommodation cavity may be composed of the support portion 120, and the support portion 120 may be disposed around the periphery of the cargo to restrict a position of the cargo and prevent the cargo from tipping.
[0072] Some embodiments of the present disclosure are capable of adapting to different sizes of cargo by setting up the first pallet 100 with the first state and the second state, which extends use scenarios of the first pallet 100. For example, as shown in FIG. 16, when the cargo has a larger bottom area and a wider overall width, the cargo may simultaneously fall on the support plate 110 and the support portion 120 of the first pallet 100 in the first state. The support surface 111 and the top surface of the support portion 120 are in contact with the bottom surface of the cargo, and the support plate 110 and the support portion 120 may support the cargo together. As another example, as shown in FIG. 18, when the bottom surface area of the cargo is smaller and the overall width is narrower, the first pallet 100 in the first state may be switched to the second state, so that the cargo is better supported by the accommodation cavity, which enables the cargo to be stably supported during transportation, prevents the cargo from being shaken and tipped over during logistics, and reduces logistics loss.
[0073] The first pallet 100 may be set up in a variety of ways such that the first pallet 100 may be switched between the first state and the second state.
[0074] For example, the support portion 120 includes a first support unit and a second support unit that are disposed opposite each other, and a third support unit and a fourth support unit that are disposed opposite each other. The first support unit, the second support unit, the third support unit, and the fourth support unit extend along different extension directions of the support plate, respectively. The first support unit and the second support unit are connected to sides of the support plate, and the third support unit and the fourth support unit are not connected to the sides of the support plate. When the first pallet switches from the first state to the second state, the support plate may be configured to drive the first support unit and the second support unit to flip; and when the first pallet is in the second state, top surfaces of the first support unit and the second support unit in the first state are arranged oppositely along a height direction, and the top surfaces of the first support unit and the second support unit in the first state, and inner side surfaces of the third support unit and the fourth support unit surround each side of the support plate to form the accommodation cavity with the support plate. More information on the foregoing examples can be found in the relevant descriptions below.
[0075] Further example, the first pallet 100 further includes a base, the support plate and the support portion are both disposed at the top portion of the base along a height direction, and a resilient support member is disposed between the support plate and the base. The support plate is configured to move between an initial position and a target position relative to the base to cause the first pallet to switch between the first state and the second state. When the support plate moves from the initial position to the target position under an external force, the first pallet may be configured to switch from the first state to the second state, and when the external force is withdrawn, under a resilient restoration force of the resilient support member, the support plate may be configured to move back to the initial position, and the first pallet may be configured to switch from the second state to the first state. More descriptions for on the foregoing example can be found in related descriptions below.
[0076] In some embodiments, the first pallet 100 in the first state may be switched to the second state in a variety of ways. For example, a downward force (e.g., manually applying a downward force to the support plate 110) may be applied to the support plate 110 to cause the first pallet 100 in the first state to switch to the second state. Furthermore, for example, when a cargo is placed on the support plate 110 of the first pallet 100 in the first state, the support plate 110 may sink when subjected to the downward gravitational force of the cargo, causing the first pallet 100 in the first state to automatically switch to the second state, so that the first pallet 100 can be automatically switched to the second state when needed, avoiding manual adjustment of a state of the first pallet 100 and reducing costs.
[0077] In some embodiments, the first pallet 100 may include other structures. For example, as shown in FIG. 1A, the first pallet 100 may also include a connection assembly, and the connection assembly may connect the first pallet 100 to other pallets. More descriptions about the connection assembly can be found in the relevant description below in the present disclosure.
[0078] In some embodiments, a material of the first pallet 100 may include paper, wood, plastic, metal, or the like, or a combination thereof. Materials used for different structures in the first pallet 100 may be the same or different.
[0079] In some embodiments, the cargo fixation device 10 may include only the first pallet 100.
[0080] In some embodiments, the cargo fixation device 10 may include a second pallet 200 and / or a third pallet 300 in addition to the first pallet 100. The second pallet 200 and the third pallet 300 are two pallets connected to the first pallet 100, respectively.
[0081] In some embodiments, the cargo fixation device 10 may include a plurality of pallets that are connected in sequence. As shown in FIG. 1B, the cargo fixation device 10 may include the first pallet 100, the second pallet 200, and the third pallet 300, the first pallet 100 may be connected with the second pallet 200 and the third pallet 300.
[0082] Each pallet (e.g., the first pallet 100, the second pallet 200, the third pallet 300, etc. ) of the cargo fixation device 10 may be provided with a connection assembly, and two pallets of the cargo fixation device 10 may be connected to each other by the connection assembly of each of the two pallets.
[0083] In some embodiments, the plurality of pallets of the cargo fixation device 10 (e.g., the first pallet 100, the second pallet 200, the third pallet 300, etc. ) is identical in structure, and the plurality of pallets may be connected by the connection assembly. In some embodiments, the plurality of pallets of the cargo fixation device 10 (e.g., the first pallet 100, the second pallet 200, the third pallet 300, etc. ) is different in structure, but connection assemblies of two adjacent pallets may be connected. Exemplarily, the plurality of pallets of the cargo fixation device 10 has different structures, but positions and the structures of connection assemblies of two adjacent pallets may be matched, so the two adjacent pallets with different structures may be connected by the matched connection assemblies of the two adjacent pallets.
[0084] For example, the cargo fixation device 10 includes the first pallet 100 and the second pallet 200, the first pallet 100 and the second pallet 200 are identical in structure, and the first pallet 100 and the second pallet 200 may be connected through respective connection assembly. As another example, the cargo fixation device 10 includes the first pallet100 and the third pallet 300, the first pallet 100 and the third pallet 300 are identical in structures, the first pallet 100 and the third pallet 300 being connectable to each other through respective connection assembly. As another example, the cargo fixation device 10 includes the first pallet100, the second pallet 200, and the third pallet 300, the first pallet 100, the second pallet 200, and the third pallet 300 are different in structures, but the first pallet 100 may be connected to the connection assembly of the second pallet 200 and the connection assembly of the third pallet 300 via the connection assembly of the first pallet 100.
[0085] In some embodiments, the connection assembly may include a first construction member 131 and a second construction member 132. Construction members (e.g., the first construction member 131 and the second construction member 132, etc. ) in two adjacent pallets that needed to be connected may be matched in structure and position, so that a particular pallet may be connected to the second construction member 132 of another pallet via the first construction member 131 of the particular pallet, thereby realizing a connection between two pallets. For example, the first construction member 131 of the first pallet 100 may be configured to match and cooperate with the second construction member 132 in the connection assembly of the second pallet 200 to realize a connection between the first pallet 100 and the second pallet 200. A particular pallet may also be connected to the first construction member 131 of yet another pallet via the second construction member 132 of the particular pallet to effectuate a connection between the two pallets. For example, the second construction member 132 of the first pallet 100 may be configured to match and cooperate with the first construction member 131 in the connection assembly of the third pallet 300 to effectuate a connection between the first pallet 100 and the third pallet 300. It will be appreciated that a pallet in the cargo fixation device 10 may be connected to only one pallet via the first construction member 131 or the second construction member 132, or connected to two pallets via the first construction member 131 and the second construction member 132. Specific structures of the first construction member 131 and the second construction member 132 can be found in the relevant descriptions below in the present disclosure.
[0086] In some embodiments, each pallet in either the first state or the second state may be connected to another pallet via the second construction member 132 or the first construction member 131.
[0087] In some embodiments, the first construction member 131 may include a slot and the second construction member 132 may include an insert. As shown in FIG. 2, the support portion 120 of the first pallet 100 is provided with a slot 1311 and an insert 1321, and the insert 1321 may be provided in the slot 1311. The slot 1311 and the insert 1312 may be both disposed on each of a plurality of side surfaces of the support portion 120 of the first pallet 100, and the first pallet 100 may be connected with different pallets through the slot 1311 and the insert 1321 on each of different side surfaces. When a plurality of pallets need to be connected to each other, the insert 1321 in the first pallet 100 may be inserted into a slot 1311 of a second pallet, and an insert 1321 of a third pallet may be inserted into the slot 1311 of the first pallet 100. In some embodiments, each of a plurality of sides of the support portion of the pallet may be provided with the slot and the insert to ensure that pallets in same or different states may be connected. For example, pallets in first states may be connected via the slot and the insert. Furthermore, for example, when one pallet is in a first state and the other pallet is in a second state, the two pallets may be connected via the slot and the insert. As another example, when both pallets are in a second state, the two pallets may also be connected via the slot and the insert. In some embodiments, when each of the plurality of sides of the support portion of the pallet is provided with the slot and the insert, a plurality of pallets may be connected along the height direction, extending a use scenario of the cargo fixation device 10. For example, when a slot and an insert are provided on the bottom surface of one pallet, and a slot and an insert are provided on the top surface of another pallet, the two pallets may be connected along the height direction.
[0088] In some embodiments, the first construction member 131 and the second construction member 132 may include hooks, and different pallets may be connected to by the hooks. In some embodiments, each of the hooks may be opened and closed.
[0089] In some embodiments, each of the first construction member 131 and the second construction member 132 in the first pallet 100 may include a touch fastener. The first construction member 131 and the second construction member 132 may be a hook side of the touch fastener and a hair side of another touch fastener, respectively, and a connection between different pallets may be realized by Velcro lamination.
[0090] In some embodiments, when the pallet in the first state (e.g., the first pallet 100, the second pallet 200, the third pallet 300, etc. ) switches to the second state, the pallet may be automatically connected to one or more pallets, simplifying an installation operation of the pallet and facilitating the use of the cargo fixation device 10.
[0091] In some embodiments, the first construction member 131 may include an insertion member, and the second construction member 132 may include an insertion slot, and when the first pallet 100 in the first state shits to the second state, the insertion member in the first pallet 100 may extend out of the first pallet 100 and extend into the insertion slot in the second pallet 200, thereby realizing a connection between the first pallet 100 and the second pallet 200. In some embodiments, similarly, when the third pallet 300 in the first state switches to the second state, an insertion member in the third pallet 300 may extend out of the third pallet 300 and into the insertion slot in the first pallet 100, thereby realizing a connection between the first pallet 100 and the third pallet 300.
[0092] In some embodiments, the insertion member may include a first insertion member 1312, and the insertion slot may include a first insertion slot 1322, and more information about the first insertion member 1312 and the first insertion slot 1322 can be found in the related descriptions below.
[0093] In some embodiments, the insertion member may include a second insertion member 1313, and the insertion slot may include a second insertion slot 1323, and more information about the second insertion member 1313 and the second insertion slot 1323 can be found in the related description below.
[0094] In some embodiments, the insertion member may include a third insertion member 1319, and the insertion slot may include a third insertion slot. The support plate 110 may include a protruded member 117, and the support portion 120 is provided with a third through-hole 1201 and a fourth through-hole 1202. The third through-hole 1201 is disposed on an inner side surface of the support portion 120 that is close to the support plate 110, the fourth through-hole 1202 is disposed on an outer side surface of the support portion 120 away from the support plate 110, the protruded member 117 extends into the support portion 120 from the third through-hole 1201. A third insertion member 1319 is provided in correspondence with the fourth through-hole 1202, the third insertion member 1319 overlaps with a projection of the protruded member 117 along the height direction, and a size of an end of the third insertion member 1319 close to the protruded member 117 gradually increases from top to bottom along the height direction. As shown in FIG. 3A, the first pallet 100 is in the first state, at which time, the third insertion member 1319 may be disposed in the support portion 120, and when the support plate 110 is subjected to a downward force (e.g., the gravity of a cargo) along the height direction, the support plate 110 moves downwardly along the height direction, and at the same time, the protruded member 117 is driven to move downwardly, and as the third insertion member 1319 overlaps with the projection of the protruded member 117 along the height direction, the size of the end of the third insertion member 1319 close to the protruded member 117 gradually increases from top to bottom along the height direction, when the protruded member 117 is driven to move downward, the third insertion member 1319 may be driven to extend out of the support portion 120 via the fourth through-hole 120 to cause the first pallet 100 in the second state as illustrated in FIG. 3B, so that a connection between the first pallet and the insertion slot of other pallets may be realized.
[0095] In some embodiments, as shown in FIG. 3A, the size of the end of the protruded member 117 close to the third insertion member1319 gradually increases from top to bottom along the height direction, and an end surface of the third insertion member 1319 contacting with the protruded member 117 and an end surface of the protruded member 117 contacting with the third insertion member 1319 are parallel, which may make a contact area between the third insertion member 1319 and the protruded member 117 larger after the third insertion member 1319 extends out of the support portion 120, thereby facilitating the protruded member 117 to support the third insertion member 1319 and improving the stability of a connection between pallets.
[0096] In some embodiments, as shown in FIG. 3A, the third insertion member 1319 may be provided with a position-limiting block 134 and a fourth spring 135. One end of the fourth spring 135 may be connected to the inner wall of the support portion 120, and the other end of the fourth spring 135 may be connected to the position-limiting block 134, and the position-limiting block 134 may be connected to the third insertion member 1319. As shown in FIG. 3A and FIG. 3B, when the third insertion member 1319 extends out of the support portion 120, the fourth spring 135 may be driven to deform. When the force subjected by the support plate 110 along the height direction disappears (e.g., the cargo is taken away and the gravity of the cargo disappears) , the deformed fourth spring 135 restores its initial state, which generates a resilient force, and the resilient force drives the third insertion member 1319 back to the support portion 120, driving the support plate 110 to move upwardly along the height direction, which can make the first pallet 100 automatically switch from the second state to the first state, avoiding manual adjustment of the state of the first pallet 100 and facilitating use.
[0097] Some embodiments of the present disclosure may connect a plurality of pallets in the cargo fixation device 10 through the connection assembly of each of the plurality of pallets, so as to increase the bottom area of the cargo fixation device 10, enhance the anti-dumping capability of the plurality of pallets in the process of transportation, and a plurality of neighboring pallets may be kept relatively stationary, improving the stability of the plurality of pallets in the process of transportation, and at the same time, an interconnection between the plurality of pallets may also enable the plurality of pallets to form a whole with a larger volume and occupying a larger area, further preventing the cargo from tipping over or overturning in the process of transportation. Exemplarily, when a transportation vehicle is braking sharply or turning a corner, a cargo on a pallet may tilt, driving corresponding pallet to tilt, at which time, other interconnected pallets may be able to limit positions of the pallet, so as to restore the initial state of the pallet and improve the stability in the process of transportation.
[0098] A pallet in the cargo fixation device 10 may be described below in the present disclosure using the first pallet 100 as an example. Structures of other pallets in the cargo fixation device 10 may be the same or similar to the first pallet 100.
[0099] The support portion 120 may include a first support unit 121, a second support unit 122, a third support unit 123, and a fourth support unit 124. The first pallet 100 shown in FIG. 4A is in the first state, the support surface 111 is at the same level as the top surface of the support portion 120, and The first support unit 121 and the second support unit 122 are disposed opposite to each other, the third support unit 123 and the fourth support unit 124 are disposed opposite to each other, and the first support unit 122, the second support unit 123, the third support unit 123, and the fourth support unit 124 are disposed along extension directions of the support plate 110, respectively. The first support unit 121 and the second support unit 122 are connected to sides of the support plate 110, and the third support unit 123 and the fourth support unit 124 are not connected to the sides of the support plate 110.
[0100] FIG. 4B shows a transition process of the first pallet 100 switching from the first state shown in FIG. 4A to the second state, and FIG. 4C shows the second state of the first pallet 100. The support plate 110 sinks during the transition process and when the first pallet 100 is in the second state. As the first support unit 121 and the second support unit 122 are connected to the sides of the support plate 110, the sinking of the support plate 110 may drive the first support unit 121 and the second support unit 122 to flip, and as the third support unit 123 and the fourth support unit 124 are not connected to the sides of the support plate 110, the sinking of the support plate 110 may not cause the third support unit 123 and the fourth support unit 124 to change. Only by way of illustration, as shown in FIG. 4A, the top surface of the second support unit 122 is provided with a label A, and the top surface of the third support unit 123 is provided with a label B, and when the first pallet 100 switches from the first state to the second state, the label A is flipped along with the second support unit 122 to a position shown in FIG. 4B, and then is flipped to a position shown in FIG. 4C, while a position of the label B is not changed.
[0101] When the first pallet 100 in the first state as shown in FIG. 4A is switched into the second state as shown in FIG. 4C, the first support unit 121 and the second support unit 122 in the first state are opposite each other along the top surface, top surfaces of the first support unit 121 and the second support unit 121 in the first state and inner side surfaces of the third support unit 123 and the fourth support unit 124 surround sides of the support plate 110 to form an accommodation cavity with the support plate 110. The cargo is placed in the accommodation cavity, and the first support unit 122, the second support unit 123, the third support unit 123, and the fourth support unit 124 may work together to act as a gripper and an enclosure for the cargo. The third support unit 123 and the fourth support unit 124 are not connected to the support plate 110, so that the third support unit 123 and the fourth support unit 124 can play a restraining role on the first support unit 122 and the second support unit 123 to prevent the first support unit 122 and the second support unit 123 from rotating along a direction far away from a center of the first pallet 100 when the cargo is tipped over, thereby ensuring that the first pallet 100 in the second state is stable, further enhancing a support function of the first pallet 100.
[0102] In some embodiments, as shown in FIG. 4A, the support plate 110 in the first pallet 100 has two first sides 1101 extending along a length direction and two second sides 1102 extending along a width direction, the first support unit 121 and the second support unit 122 are disposed on the different first sides 1101, respectively, the third support unit 123 and the fourth support unit 124 are disposed on the different second sides 1102, respectively. A first cutting slot 112 is provided between one second side 1102 of the support plate 110 and the third support unit 123, and a second cutting slot 112 is provided between the other second side 1102 of the support plate 110 and the fourth support unit 124, and the support surface 111 is disposed between the first support unit 121, the second support unit 122, the first cutting slot 112, and the second cutting slot 113.
[0103] When the first pallet 100 switches from the first state to the second state as shown in FIG. 4A, the support surface 111 sinks (i.e., moves downwardly along the height direction) to drive the first support unit 121 and the second support unit 1022 to rotate along the first side 1101, and the third support unit 123 and the fourth support unit 124 remain stationary. By the above-described setting, the support surface 111 may be adapted to a cargo with a narrower width, and the support plate 110 may drive the first support unit 121 and the second support unit 122 to rotate around the first side 1101 toward the cargo under the driving of the cargo. By setting the first cutting slot 112 and the second cutting slot 113, the third support unit 123 and the fourth support unit 124 may not rotate relative to the cargo under an action of the support plate 110, which can restrain the first support unit 121 and the second support unit 122 and ensure an overall structural stability of the first pallet 100.
[0104] In some embodiments, the first support unit 121 and the second support unit 122 may be located at the different second sides 1102, and the third support unit 123 and the fourth support unit 124 may also be located at different first sides 1101, cutting slots are provided between the two first sides 1101 of the support plate 110 and the third support unit 123 and the fourth support unit 124, respectively, as long as a dimension of the cargo may be matched and the third support unit 123 and the fourth support unit 124 may restrain the first support unit 121 and the second support unit 122.
[0105] In some embodiments, the support portion 120 is provided with a reinforcement structure, and the reinforcement structure is configured to increase the support strength of the support portion 120. The support portion 120 may be an internal hollow structure, and a top surface of the reinforcement structure may be in contact with an internal top surface of the support portion 120, and a bottom surface of the reinforcement structure may be in contact with an internal bottom surface of the support portion 120. The resistance level to deformation of the reinforcement structure along the height direction of the support portion 120 is greater than the resistance level to deformation of the support portion 120 along the height direction of the support portion 120.
[0106] Exemplarily, the reinforcement structure may be an elongate structure (e.g., a second reinforcement strip 160) that extends along a length direction of the support portion 120, the height of the elongate structure is the same as, or approximate to, the height of an internal hollow of the support portion 120, and the resistance level to deformation of the elongate structure along the height direction of the support portion 120 is greater than the resistance level to deformation of the support portion 120 along the height direction of the support portion 120, which may increase the support strength of the support portion 120.
[0107] The reinforcement structure can prevent the support portion 120 from being deformed by the load of the cargo, and enhance the structural performance of the support portion 120 as a whole. When the first pallet 100 is in the first state, the reinforcement structure can enhance the support performance of the support portion 120, and when the first pallet 100 is in the second state, the reinforcement structure can enhance the structural strength, better enclosing and supporting the cargo.
[0108] In some embodiments, the support surface 111 of the support plate 110 is provided with a reinforcement member, and the reinforcement member is adapted to a shape of a projection of the support surface 111 along the height direction to ensure that the reinforcement member may be placed on the support surface 111, and when the first pallet 100 is in the second state, the reinforcement member may not move back and forth or move left to right in the accommodation cavity. For example, the reinforcement member may be a reinforcement plate 114 as illustrated in FIG. 7, which is adapted to the shape of the projection of the support surface 111 along the height direction, and the reinforcement plate 114 is capable of enhancing a structural strength of the support plate 110, preventing the support plate 110 from breaking, which causes the cargo to sink directly through a broken place without causing the support plate 110 to sink as well, and thus ensuring the usability of the pallet. As another example, the reinforcement member may be provided with a slot, and a shape and size of the slot may be adapted to a structure of the cargo at a corresponding position, so as to better fix the cargo, and improve the stability of the cargo when being transported. As another example, the reinforcement member may be a multi-layer structure, and a material of the multi-layer structure may be adjusted as needed. For example, the multi-layer structure may include materials such as sponge, rubber, and other materials for reducing vibration to reduce vibration of the cargo when being transported, thereby avoiding damage to the cargo.
[0109] In some embodiments, the reinforcement member may be provided with an anti-slip structure. For example, the reinforcement member may be provided with a rubber cam, and the rubber cam may increase a friction between the reinforcement member and the cargo, improving the stability of the cargo when being transported.
[0110] In some embodiments, the reinforcement member may be placed directly on the support surface 111. In some embodiments, the reinforcement member may be removably disposed on the support surface 111. Exemplarily, the reinforcement member and the support surface 111 may be removably coupled via Velcro to facilitate replacement of the reinforcement member as needed. Exemplarily, the reinforcement member may be replaced as needed based on a broken situation of the reinforcement member. Furthermore, for example, the reinforcement member may be replaced according to the shape of a cargo to be transported.
[0111] The material of the reinforcement member may be the same as a material of the first pallet 100, e.g., the reinforcement member and the first pallet 100 may both be of paper construction or plastic construction. In some embodiments, the material of the reinforcement member may be different from the material of the first pallet 100, for example, the reinforcement member may be made of metal.
[0112] In some embodiments, the first pallet 100 may be set up with the first construction member 131 and the second construction member 132 in a variety of ways to enable a connection between different pallets. For example, the first pallet 100 of the foregoing setup may be set up in a variety of ways to realize the connection between different pallets through the first construction member 131 and the second construction member 132 as shown in some of the previous embodiments of the present disclosure. As another example, the first pallet 100 may realize the connection between different pallets through the first insertion member 1312 and the first insertion slot 1322 according to some embodiments below of the present disclosure.
[0113] In some embodiments, the first construction member 131 includes the first insertion member 1312, the second construction member 132 includes the first insertion slot 1322, the first insertion member 1312 and the first insertion slot 1322 are disposed on two opposite sides of the first pallet 100. In some embodiments, the first pallet 100 may include more than one first insertion member 1312 and more than one first insertion slot 1322.
[0114] In some embodiments, the first insertion slot 1322 may be provided on the first support unit 121 or the second support unit 122. Exemplarily, the first insertion slot 1322 is provided on the first support unit 121 of the first pallet 100 as shown in FIG. 8. More information about the first insertion member 1312 can be found in the relevant description below in the present disclosure.
[0115] In some embodiments, the first insertion member 1312 may switch between a first avoidance position and a first insertion position. When the first insertion member 1312 is located in the first avoidance position, at that time, the first insertion member 1312 is not protruding out of the side of the first pallet 100 and may not cooperate and insert with the first insertion slot 1322 of the second pallet 200. When the first insertion member 1312 is disposed at the first insertion position, at this time, the first insertion member 1312 is provided to protrude out of the side of the first pallet 100 and may cooperate and insert with the first insertion slot 1322 of the second pallet 200. Through the above-described setting, when a plurality of pallets are transported, the plurality of pallets may be connected to each other through the first insertion member 1312 and the first insertion member slot 1322, which can further enhance the anti-tipping ability of the pallets during transportation. When a transportation vehicle brakes sharply or turns, a plurality of adjacent pallets may remain relatively stationary to ensure the stability of the plurality of pallets in the process of transportation.
[0116] In some embodiments, as shown in FIG. 8, the first pallet 100 may include a first reinforcement strip 150 extending along a length direction of the first pallet 100, and the first reinforcement strip 150 is provided with the first insertion member 1312.
[0117] As shown in FIG. 4A, when the first pallet 100 is in the first state, the first reinforcement strip 150 is disposed inside the first support unit 121, and a through-hole 1212 is provided at a bottom portion of the first support unit 121 (for ease of illustration, the through-hole 1212 is referred to as a first through-hole 1212) , the first insertion member 1312 on the first reinforcement strip 150 is provided aligned with the first through-hole 1212, and the first insertion member 1312 is in the first avoidance position at this time.
[0118] The first support unit 121 is provided with an avoidance opening 1211 at a top portion of the first support unit 121, the support plate 110 is provided with an abutment projection 115 on the side of the support plate 110, the abutment projection 115 is disposed at the avoidance opening 1211, and the side wall of the second support unit 122 is provided with the first insertion slot 1322.
[0119] In some embodiments, the abutment projection 115 may be provided on a plurality of structures of the first pallet 100. For example, as shown in FIG. 4A, the abutment projection 115 may be provided on the support plate 110 of the first pallet 100. As another example, as shown in FIG. 7 to FIG. 9, the abutment projection 115 may be provided on the reinforcement plate 114 of the first pallet 100. As another example, each of the support plate 110 of the first pallet 100 and the reinforcement plate 114 may both be provided with the abutment projection 115.
[0120] As shown in FIG. 4A to FIG. 4B, when the first pallet 100 switches from the first state to the second state, the first support unit 121 and the second support unit 122 are flipped over relative to the support plate 110, and the abutting protrusion 115 extends into the first support unit 121 via the avoidance opening 1211 to drive the first reinforcement strip 150 to move along a direction away from the support plate 110, and cause the first insertion member 1312 to protrude via the first through-hole 1212, at which time the first insertion member 1312 is in the first insertion position.
[0121] As shown in FIG. 4C, when the first pallet 100 is in the second state, the first insertion slot 1322 is located on a side of the second support unit 122 away from the support plate 110, thereby facilitating a connection with the first insertion member 1312 of another pallet.
[0122] In some embodiments, the first pallet 100 may be otherwise set up in a manner that may cause the first insertion member 1312 to extend out of the first through-hole 1212.
[0123] In some embodiments, the top portion of the first support unit 121 in the first pallet 100 may be provided with a position-limiting hole 1213. The first reinforcement strip 150 may be provided with a position-limiting member 151, and the position-limiting member 151 may be movable within the position-limiting hole 1213. As shown in FIG. 5A and FIG. 5B, the position-limiting hole 1213 may include a first position-limiting portion that extends along the width direction of the first pallet 100, and the position-limiting member 151 may move within the first position-limiting portion, thereby driving the first insertion member 1312 provided on the first reinforcement strip 150 to extend out of or enter the first support unit 121, to realize automatic control of the first insertion member 1312. The first insertion member 1312 may be driven to switch between the first avoidance position and the first insertion position as needed, and avoid the damage caused by the first insertion member 1312 also extending out of the side of the first pallet 100 when a plurality of pallets are not required to be connected.
[0124] It should be noted that the position-limiting hole 1213 may be disposed on the top portion of the first support unit 121 of the first pallet 100 in the first state, or may be provided on the top portion of the first support unit 121 of the first pallet 100 in the second state.
[0125] In some embodiments, as shown in FIG. 5B and FIG. 5C, the position-limiting hole 1213 may further include a second position-limiting portion extending along the length direction of the first pallet 100, the first position-limiting portion and the second position-limiting portion are connected, and the position-limiting member 151 may move within the second position-limiting portion, thereby fixing a position of the first insertion member 1312 along the width direction of the first pallet 100 and safeguarding the stability of the plurality of pallets when being connected.
[0126] In some embodiments, a fifth spring 1214 may be provided in the first support unit 121. One end of the fifth spring 1214 may be connected to a side edge of the first reinforcement strip 150, and the other end of the fifth spring 1214 may be connected to the inner wall of the first support unit 121. The side edge of the first reinforcement strip 150 is symmetrical with a side surface of the first reinforcement strip 150 in which the first insertion member 1312 is provided. As shown in FIG. 6A, when the first pallet 100 is in the first state, the fifth spring 1214 is in a compressed state, the first through-hole 1212 is obstructed by the ground or other items, and the first insertion member 1312 is in the first avoidance position. As shown in FIG. 6B, when the first pallet 100 in the first state is switched to the second state, the first support unit 121 is flipped over, driving the first through-hole 1212 to be exposed, and the fifth spring 1214 generates a resilient force, so that the first insertion member 1312 may be driven to extend out of the first through-hole 1212, the first insertion member 1312 is in the first insertion position, and the first insertion member 1322 may be connected to the first insertion slot 1322 of another pallet.
[0127] Some embodiments of the present disclosure, through the settings, can make the pallet (e.g., the first pallet 100) connect with an adjacent pallet (e.g., the second pallet 200, the third pallet 300) through the first insertion member 1312 and the first insertion slot 1322 when switching to the second state, thereby improving the relative stability between the two adjacent pallets. When one of the pallets is shaken to cause the cargo to fall over, the other pallet may play a role in limiting each other to prevent the cargo from falling over and reduce the logistics loss caused by improper transportation.
[0128] In some embodiments, as shown in FIG. 4A, the first pallet 100 further includes a second reinforcement strip 160 disposed within the second support unit 122 along the length direction of the first pallet 100. Providing the first reinforcement strip 150 and / or the second reinforcement strip 160 extending along the length direction can prevent the support portion 120 from being deformed by a load of the cargo, and improve the structural performance of the support portion 120 as a whole. When the first pallet 100 is in the first state, the first reinforcement strip 150 and the second reinforcement strip 160 can enhance the supporting performance of the support portion 120. When the first pallet 100 is in the second state, the first reinforcement strip 150 and the second reinforcement strip 160 can enhance the structural strength of the support portion 120, thereby better enclosing and supporting the cargo.
[0129] In some embodiments, the first reinforcement strip 150 and the second reinforcement strip 160 may be fixed in the support portion 120 in a variety of ways, and a fixation manner of the first reinforcement strip 150 and the second reinforcement strip 160 and the support portion 120 may be the same or different. For example, the first reinforcement strip 150 and the second reinforcement strip 160 may be fixed in the first support unit 121 and the second support unit 122, respectively, by gluing, so that when the first pallet 100 is in the first state, it can be ensured that the first reinforcement strip 150 and the second reinforcement strip 160 may not move within the first support unit 121 and the second support unit 122, thereby ensuring the structural stability of the first reinforcement strip 150 and the second reinforcement strip 160, and when the first pallet 100 is in the second state, the first reinforcement strip 150 may be subjected to an action of the abutment projection 115 and be dislodged from the first support unit 121, thereby realizing that the first insertion member 1312 extends out of the first through-hole 1212 through movement and ensuring the use performance of the first reinforcement strip 150. As another example, the first reinforcement strip 150 and the second reinforcement strip 160 may be secured by Velcro in the first support unit 121 and the second support unit 122, respectively.
[0130] Based on the foregoing structural setup of the first pallet 100 shown in some embodiments of the present disclosure, a process of interconnecting two adjacent pallets may be as follows:
[0131] When a narrower and taller cargo is placed on the support plate 110, the support plate 110 sinks to drive the first support unit 121 and the second support unit 122 to flip over, the first insertion member 1312 located in the first support unit 121 may extend out of the first support unit 121 and be inserted into the first insertion member 1312 of the other pallet (e.g., the second pallet 200) to connect the two adjacent pallets.
[0132] The manner in which the first pallet 100 described in some of the foregoing embodiments is produced and assembled is described below in the present disclosure.
[0133] In some embodiments, each side of the support plate 110 is provided with a folding plate. The folding plate may include a plurality of interconnected folding zones 140. The plurality of folding zones 140 that are on the same folding plate are folded along a same direction to form the support portion 120 with a hollow cavity. By the above-described setting, the plurality of interconnected folding zones 140 may be folded multiple times to form the support portion 120, which facilitates the production and processing of the pallet. When there is no need to use the pallet, the folding plate is not folded, which can reduce an occupancy space of the pallet, and when there is a need to use the pallet, the support portion 120 may be formed by folding the folding zones 140 multiple times.
[0134] Referring to FIG. 12 to FIG. 14, a count of the plurality of folding zones may be set to 4, so that a cross-sectional shape of the support portion 120 formed by the folding zones after folding is rectangular along a radial direction, which can improve the support performance and structural stability of the support portion 120.
[0135] Between two adjacent folding zones 140, a connection between the support plate 110 and the folding plate may be pre-machined with a knife mold line, so as to facilitate the folding of the folding zones 140, constrain a dimension of the folding zones 140, and ensure that structural dimensions of each of the support units in the support portion 120 are compatible, thereby ensuring that the pallet can smoothly carry the cargo.
[0136] In some embodiments, a gluing plate may be provided on the folding zone 140 away from the support plate 110, and the gluing plate is subjected to gluing, and the folding zone 140 on a side proximate to the support plate 110 and the folding zone 140 on a side remote from the support plate 110 may be glued through the gliding plate to further enhance the structural strength of the support portion 120 and improve the stability of the pallet.
[0137] In some embodiments, the support plate 110 is provided with a connection tab 116. A connection hole 125 is provided on a side wall of at least one of the third support unit 123 and the fourth support unit 124 toward the support plate 110, and the connection tab 116 is disposed within the connection hole 125 to restrict at least one of the third support unit 123 and the fourth support unit 124 from moving relative to the support plate 110. Through the above-described setting, the structural strength of the third support unit 123 and the fourth support unit 124 may be ensured, preventing the third support unit 123 and the fourth support unit 124 formed through folding from deforming and loosening under pressure, thereby ensuring the structural stability of the first pallet 100. In some embodiments, one of the first support unit 121 and the second support unit 122 may be provided with the connection hole 125, and the connection hole 125 may be inserted and fixed to the connection tab 116 to further enhance the structural stability of the first support unit 121 and the second support unit 122.
[0138] In some embodiments, at least a portion of the support portion 120 is integrally molded with the support plate 110. For example, the support portion 120 as a whole is integrally molded structure with the support plate 110. As another example, a portion of the support portion 120 is an integrally molded structure with the support plate 110.
[0139] The support portion 120 and the support plate 110 may be made of a plurality of materials. For example, the support plate 110 and the plurality of folding plates are cut and molded from cardboard in one piece. As another example, the support plate 110 and the plurality of folding plates may be integrally molded from plastic (e.g., polyvinyl chloride, polypropylene, etc. ) . As another example, the support plate 110 and the plurality of folding plates may also be made of metal, and folding plates needed to be folded may be connected to each other by hinges. With the above setup, when there is no need to use the first pallet 100, the first pallet100 may not be folded, and the first pallet 100 is stored in an unfolded form, and when there is a need to use the first pallet 100, the first pallet may be quickly formed by folding, which can facilitate the production and processing of the first pallet 100, and at the same time can save the space occupied by the first pallet 100 and reduce the pressure on the storage of the first pallet 100. The use of an environmentally-friendly material to make the pallet, compared to the wooden pallet in the prior art, the first pallet 100 made of paper or plastic can achieve a certain degree of institutional strength through the folding and the production cost is lower. Moreover, the first pallet 100 can be recycled after use, which is conducive to protecting the environment and reducing material waste.
[0140] In some embodiments, the first reinforcement strip 150 and the second reinforcement strip 160 may be formed by a plurality of independent units connected together along a thickness direction, which can facilitate the production and processing of the first reinforcement strip 150 and the second reinforcement strip 160. A material of each of the first reinforcement strip 150 and the second reinforcement strip 160 may include paper, plastic, wood, or the like, or a combination thereof. When the material of the first reinforcement strip 150 and the second reinforcement strip 160 is paper or plastic, the first reinforcement strip 150 and the second reinforcement strip 160 may be cut and molded with the support plate 110 and the plurality of folding plates simultaneously. The gluing between the plurality of independent units can also further enhance the strength of the first reinforcement strip 150 and the second reinforcement strip 160, thereby enhancing the support performance of the first reinforcement strip 150 and the second reinforcement strip 160.
[0141] Some embodiments of the present disclosure illustrate a structural setup of the first pallet 100, by which the pallet may be made to automatically connect with other pallets when the pallet switches from the first state to the second state, to ensure that the pallet transports the cargo in a stability, and improve the supporting role of the pallet. Meanwhile, the pallet of the structural setup has a simple structure, low production difficulty, low cost, and is easy to store when not in use.
[0142] In some embodiments, as shown in FIG. 15, FIG. 17, FIG. 19, and FIG. 20, the first pallet 100 further includes a base 170, the support plate 110 and the support portion 120 both disposed on a top portion of the base 170, and a resilient support member 180 is disposed between the support plate 110 and the base 170. The support plate 110 is configured to move between an initial position and a target position with respect to the base 170, which can cause the first pallet 100 to switch between the first state and the second state. When the support plate 110 is acted upon by an external force (e.g. when a cargo is placed on the support surface 111 of the support plate 110, the support plate 110 is under the action of the gravity of the cargo) , the support plate 110 moves from an initial position to the target position, and the first pallet100 switches from a first state to a second state; when the external force is withdrawn (e.g., after the removal of the cargo) , and under the resilient restoring force of the resilient support member 180, the support plate 180 moves to the initial position, and the first pallet 100 switches from the second state to the first state.
[0143] Some embodiments of the present disclosure can adapt to different sizes of cargo through the first pallet 100, and when a cargo is narrower and taller, the first pallet 100 may be switched to the second state, which can provide support and fixation for the cargo through an accommodation cavity, preventing the cargo from being shaken and tipped during logistics transportation and reduce logistics loss. In addition, by providing the resilient support member 180, it is convenient for the first pallet 100 to automatically switch between the first state and the second state, which facilitates the use of the first pallet 100.
[0144] In some embodiments, as shown in FIG. 19 and FIG. 20, the resilient support member 180 may include a mounting block 181, a first guiding column 182, and a first spring 183. The mounting block 181 may be connected to the support plate 110, the first guiding column 182 may extend along a height direction of the first pallet 100, and the mounting block 181 may be movably provided on the first guiding column 182. The first guiding column 182 may be configured to guide the movement of the mounting block 181. The first spring 183 may be socketed to the first guiding column 182, one end of the first spring 183 may be fixedly connected to the mounting block 181, and the first spring 183 may be capable of providing a resilient force for the support plate 110 to move toward the initial position through the mounting block 181. With the above-described setting, when the support plate 110 is switched from the initial position to the target position by the gravity of the cargo, the mounting block 181 can compress the first spring 183, and when the support plate 110 is switched from the target position to the initial position, the support plate 183 is no longer affected by the gravity of the cargo, and the first spring 183 can drive the support plate 110 to move toward the initial position, realizing the automatic reset of the support plate 110 and avoiding manual adjustment of the state of the first pallet 100.
[0145] In some embodiments, the side wall of the accommodation cavity includes an accommodation slot provided in an annular shape, and the mounting block 181 may be provided on a side of the support plate 110 toward a bottom of the accommodation slot, and the mounting block 181 extends along a direction toward the accommodation slot, and the first guiding column 182 and a portion of the mounting block 181 are disposed in the accommodation slot. Through such an arrangement, the support plate 110 may limit a position of the support plate 110 through the accommodation slot, preventing the support plate 110 from moving excessively in the process of switching to the initial position, ensuring that a side of the support plate 110 away from a bottom of the accommodation cavity is in the same plane as a top surface of the support portion 120 when the support plate 110 is at the initial position, and thereby ensuring that the cargo can be stably placed on the support plate 110 when the support plate 110 is at the initial position.
[0146] In some embodiments, the first pallet 100 may include only one resilient support member 180. In some embodiments, the first pallet 100 may be provided with a plurality of resilient support members 180, and the plurality of resilient support members 180 may be spaced apart at the bottom portion of the support plate 110 and the accommodation cavity to ensure stabilization of the support plate 110 when switching between the initial position and the target position. In some embodiments, the plurality of resilient support members 180 may be arranged as an annular shape at the bottom portion.
[0147] In some embodiments, the first pallet 100 of the foregoing setup may be set up in a variety of ways with the first construction member 131 and the second construction member 132 to enable a connection between different pallets. For example, the first construction member 131 and the second construction member 132 may include a locking element and a control element in a locking mechanism on the side (e.g., the side of the support portion 120 or the base 170) of the first pallet 100, respectively, and the different pallets may be structurally connected by the locking mechanism in either the same or different states.
[0148] In some embodiments, the first construction member 131 and the second construction member 132 are disposed on two opposite sides of the base 170. The first construction member 131 may include the second insertion member 1313 and the second construction member 132 may include the second insertion slot 1323. The second insertion member 1313 may have a second insertion position and a second avoidance position that are disposed relatively to each other, and when the second insertion member 1313 is located at the second insertion position, the second insertion member 1313 may protrude out of the first pallet 100, for example, disposed on the side of the support portion 120 or the base 170 and may be capable of being inserted to the second insertion slot 1323 of the second pallet 200. A driving structure may be provided between the resilient support member 180 and the first construction member 131, and when the support plate is switched from the initial position to the target position, the second insertion member 1313 may switch to the second insertion position driven by the driving structure. With the above-described setting, when the cargo fixation device includes the plurality of pallets, the plurality of pallets may be connected to each other via the second insertion member 1313 and the second insertion slot 1323, which can further enhance the anti-tipping ability of the plurality of pallets during transportation. When the transportation vehicle brakes sharply or turns, a plurality of adjacent pallets can be kept relatively stationary to ensure the stability of the plurality of pallets in the process of transportation, and at the same time, the plurality of pallets can be connected with each other to enable the plurality of pallets to form a larger volume and a larger area to prevent the cargo from tipping over or overturning in the process of transportation.
[0149] In some embodiments, the driving structure may include a first stopping piece 191, a second stopping block 192, a second guiding column 193, and a second spring 194. As shown in FIG. 21 and FIG. 22, the first stopping piece 191 is provided on the resilient support member 180, the second stopping block 192 is provided on the second insertion member 1313. One end of the second guiding column 193 is connected (e.g., fixedly connected) to the second stopping block 192 and the other end of the second guiding column 193 is connected (e.g., fixedly connected) to the base 170. The second spring 194 is socketed to the second guiding column 193, one end of the second spring 194 is connected to the second stopping block 192, and the second spring 194 is configured to provide a resilient force for the second insertion member 1313 to switch from the second avoidance position to the second insertion position. When the support plate 110 is in the initial position, the second stopping block 192 and the first stopping piece 191 abut against each other to keep the second insertion member 1313 located at the second avoidance position, and when the support plate 110 is switched from the initial position to the target position, the first stopping piece 191 is lowered along with the mounting block 181, the first stopping piece 191 is separated from the second stopping block 192, and the second insertion member 1313 is switched from the second avoidance position to the second insertion position driven by the second spring 194. When the support plate 110 is switched from the initial position to the target position, the first stopping piece 191 may be driven down by the descent of the support plate 110, so that the second spring 194 drives the second insertion member 1313 from the second avoidance position to the second insertion position, realizing a connection between two adjacent pallets.
[0150] In some embodiments, as shown in FIG. 19 and FIG. 20, the first stopping piece 191 may be provided on the mounting block 181, to enable the first stopping piece 191 to support the support plate 110. In some embodiments, the same mounting block 181 may be provided with two first stopping pieces 191, and the two first stopping pieces 191 may be symmetrically provided on two sides of the mounting block 181, to further improve the support effect of the first stopping pieces 191 on the support plate 110 and to facilitate the installation of the mounting block 181.
[0151] In some embodiments, the first construction member 131 further includes a first mounting seat 1314, the first mounting seat 1314 is provided on the support portion 120 and the first mounting seat 1314 is opened with a mounting slot 1315. The second insertion member 1313 is provided within the mounting slot 1315, and the mounting slot 1315 extends along a movement direction of the second insertion member 1313. With the above-described setting, the mounting slot 413 may provide a guiding effect for the movement of the second insertion member 411, facilitating the switching of the second insertion member 411 between the second insertion position and the second avoidance position.
[0152] In some embodiments, as shown in FIG. 22, the guiding slot 1316 may also be provided on a side of the mounting slot 413 toward the second spring 194, and the second stopping block 192 may be movably disposed within the guiding slot 1316 to further guide and limit a position of the second insertion member 1313 and the second stopping block 192.
[0153] In some embodiments, as shown in FIG. 22, an end portion of the guiding slot 1316 may also be provided with a stopping piece 1317 to limit the movement of the second stopping block 192, and thus limit the position of the second insertion member 1313 between the second insertion position and the second avoidance position.
[0154] In some embodiments, as shown in FIG. 22, the first mounting seat 1314 may be provided with a position-limiting projection 1318, the position-limiting projection 1318 being provided at an end of the second stopping block 192 away from the first stopping piece 191, and the second guiding column 193 is threaded on the position-limiting projection 1318, and the other end of the second spring 194 abuts and cooperates with the position-limiting projection 1318. With the above-described setup, the position-limiting projection 1318 can limit a position of the compression of the second spring 194, and at the same time can guide the movement of the second guiding column 193 threaded on the position-limiting projection 1318.
[0155] In some embodiments, the second construction member 132 includes a second mounting seat 1324, the second mounting seat 1324 being provided with the second insertion slot 1323. An extension direction of the second insertion slot 1323 is the same as the movement direction of the second insertion member 1313, and the second insertion slot 1323 may accommodate the second insertion member 1313, so as to realize a connection between different pallets through the insertion and cooperation between the first construction member 131 and the second construction member 132.
[0156] In some embodiments, a chamfer structure is provided around a periphery of the second insertion slot 1323, and the chamfer structure is capable of guiding the movement of the second insertion member 1313, facilitating the entry of the second insertion member 1313 into the second insertion slot 1323.
[0157] In some embodiments, a locking structure is provided between the second mounting seat 1324 and the second insertion member 1313, and the locking structure is capable of restricting the displacement of the second insertion member 1313 within the second insertion slot 1323 when the second insertion member 1313 is switched to the second insertion position. By providing the locking structure, it is possible to prevent the detachment of two pallets connected to each other along the movement direction of the second insertion member 1313, to improve the connection stability of the connection assembly, and to further ensure that the two adjacent pallets can be stably connected to each other.
[0158] In some embodiments, as shown in FIG. 23 and FIG. 24, the locking structure may include a through-hole 1331 (for ease of illustration, the through-hole 1331 is also referred to as the second through-hole 1331) , a pin 1332, and a third spring 1333. The second through-hole 1331 is provided on a side wall of the second insertion member 1313. The pin 1332 is perforated on a side wall of the second mounting seat 1324, the pin 1332 includes a free end and a locking end that are oppositely disposed, the locking end being movably disposed within the second insertion slot 1323, and the pin 1332 includes a locked position and an unlocked position that are oppositely disposed. The third spring 1333 is connected to the pin 1332 in a drive-connection manner, and the third spring 1333 provides a resilient force for the pin 1332 to move toward the locked position. When an end portion of the second insertion member 1313 is pressed against the pin 1332, the second insertion member 1313 drives the pin 1332 to move from the locked position to the unlocked position, and when the second insertion member 1313 continues to move so that the second through-hole 1331 corresponds to the pin 1332, the third spring 1333 drives the pin 1332 to insert and cooperate with the second through-hole 1331 to fix a position of the second insertion member 1313 within the second insertion slot 1323. With the above-described setup, when the second insertion member 1313 enters the second insertion slot 1323, the end portion of the second insertion member 1313 can push up on the pin 1332 and cause the third spring 1333 to be compressed, and when the second insertion member 1313 moves so that the second through-hole 1331 corresponds to the pin 1332, the pin 1332 can enter the second through-hole 1331 under the compression of the third spring 1333, thereby realizing an interlocking between the first construction member 131 and the second construction member 132 of two adjacent pallets, and realizing the connection of the pallets.
[0159] In some embodiments, a cross-sectional dimension along a radial direction of a locking end of the pin 1332 increases from the locking end to the free end, and the locking end of the pin 1332 forms a guide for the movement of the second insertion member 1313, which can facilitate the second insertion member 1313 to jack up the pin 1332 during movement for the pin 1332 entering the unlocked position.
[0160] In some embodiments, a cross-sectional dimension along a radial direction of an end of the second insertion member 1313 facing an end portion of the second insertion slot increases along a direction away from the second insertion slot 1323, thereby guiding the cooperation between the second insertion member 1313 and the pin 1332.
[0161] In some embodiments, the cross-sectional dimension along a radial direction of the locking end of the pin 1332 increases from the locking end to the free end, and the cross-sectional dimension of the second insertion member 1313 toward the end portion of the second insertion slot 1323 along the radial direction increases along the direction away from the second insertion slot 1323, so that a better guiding effect can be obtained, and the friction between the second insertion member 1313 and the pin 1332 can also be reduced, so as to reduce friction loss and improve the durability of the locking structure.
[0162] In some embodiments, the locking structure further includes a mounting plate 1334, the mounting plate 1334 is provided at the free end of the pin 1332, an end of the third spring 1333 is connected to a side wall of the second mounting seat 1324, and the other end of the third spring 1333 is connected to the mounting plate 1334, and the mounting plate 1334 is provided with a pull ring 1335, so that when it is necessary to separate two adjacent pallets, the pin 1332 may be switched from the locked position to the unlocked position through the pull ring 1335.
[0163] Based on the foregoing structural setup of the first pallet 100 shown in some embodiments of the present disclosure, a process of interconnecting two adjacent pallets may be as follows:
[0164] When a narrower and taller cargo is placed on the support plate 110, the support plate 110 sinks and switches to the target position, the support plate 110 drives the mounting block 31 of the resilient support member 180 and the first stopping piece 191 of the driving structure to move down, and the first stopping piece 192 detaches from the constraint of the first stopping piece 191, and the second insertion member 1313 switches from the second avoidance position to the second insertion position driven by the second spring 194 and enters the second insertion slot 1323. The end portion of the second insertion member 1313 tops up the pin 1332 in the process of entering the second insertion slot 1323, causing the pin 1332 to switch to the unlocked position. The second insertion member 1313 continues to move, and the second through-hole 1331 is removed from the second through-hole 1332 when the second through-hole 1331 corresponds to the pin 1332, the pin 1332 enters the second through-hole 1331 under the resilient force of the third spring 1333, and the pin 1332 is switched to the locked position so that the first construction member 131 and the second construction member 132 can realize a connection, and thus connect two adjacent pallets.
[0165] The process of separating two interconnected adjacent pallets may be as follows:
[0166] The cargo is moved away from the support plate 110, the support plate 110 is switched from the target position to the initial position driven by the first spring 33 of the resilient support member 180, and at this time, the second guiding column 193 affects the upward reset of the first stopping piece 191, and at this time, the pull ring 1335 may be pulled to switch the pin 1332 to the unlocked position, and the end portion of the second insertion member 1313 may be pressed to enable the second insertion member 1313 to switch to the second avoidance position, and specifically, beveled surfaces 1911 may be provided on a side of the first stopping piece 191 away from the position-limiting projection 414 and on a side of the second stopping block 192 away from the mounting block 31, respectively, so that when the first stopping piece 191 moves toward the position-limiting projection 414, the first stopping piece 191 can avoid the second stopping block 192, and when the second insertion member 1313 is switched to the second avoidance position, the resident support member 180 causes the support plate 110 to switch to the initial position under an action of a resilient force of the first spring 33, and at this time, the two adjacent pallets are separated from each other, and the pallets may be used individually or reconnected.
