The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the present specification includes any and all combinations of one or more related listed items.

[0046] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict. Obviously, the described embodiments are part of the embodiments of the present application, not all.

[0047] The forklift disclosed in the embodiments of this application, such as Figure 1 This includes the body 100a and the mast 100b. For example... Figure 2 As shown, the mast 100b includes a body 1, a first fork 2 and a second fork 3 extending from the body 1 along a first direction X, and a first support device 4 disposed on the first fork 2. The first fork 2 and the second fork 3 are spaced apart, with the side of the first fork 2 and the side of the second fork 3 facing each other being the inner side, and the side facing away from each other being the outer side. The first support device 4 is disposed on the outer side of the first fork 2. Figure 3 As shown, the first support device 4 includes a first extension wing 41, which protrudes outward from the surface of the first fork 2 and is configured to support an external object disposed on the first fork 2.

[0048] When carrying goods, the first extension wing 41 supports the part of the goods that extends beyond the first fork 2, making the force on the goods more balanced, reducing the risk of the goods tilting or tipping over, improving the reliability of forklift handling of goods, and reducing the difficulty of operation.

[0049] In some embodiments, the first extension wing 41 is rotatably connected to the first fork 2, and the first extension wing 41 is configured to rotate in a first direction X and a second direction, the second direction being opposite to the first direction X. Along the rotational trajectory of the first extension wing 41, the first extension wing 41 is in a folded state (e.g., ...). Figure 4 (as shown) and unfolded state (as shown) Figure 2 As shown in the diagram, the folding state includes folding in a first direction X and folding in a second direction. When the first extension wing 41 is in the unfolded state, the angle between the first extension wing 41 and the first fork 2 is 'a', and when the first extension wing 41 is in the folded state, the angle between the first extension wing 41 and the first fork 2 is 'b', and 'a' is greater than 'b'. In this embodiment, 90° > b ≥ 0°, and 'a' equals 90°.

[0050] During forklift operation, when the first extension wing 41 encounters an obstacle, it will rotate to a folded state to pass through the obstacle, allowing the first fork 2 to travel through the obstacle in the first or second direction. This also reduces the risk of damage to the first extension wing 41 from scraping, increasing the equipment's lifespan.

[0051] like Figure 3 As shown, the first support device 4 includes a first reset mechanism 42, which is configured to switch the first extension wing 41 between a folded state reset state and an unfolded state. Figure 2 The image shows the first extended wing 41 in its non-rotating state. Figure 4The diagram shows the first extension wing 41 configured to rotate under external force, entering a folded state. When the external force is removed, the first reset mechanism 42 returns the first extension wing 41 from the folded state to the unfolded state. The direction of the external force is perpendicular to both the rotation axis L of the first extension wing 41 and the extension direction of the first extension wing 41. The rotation axis L is perpendicular to... Figure 3 The Z-axis is parallel.

[0052] When encountering an obstacle, the first extension wing 41 rotates from the unfolded state to the folded state through the first reset mechanism 42 to pass through the obstacle. After passing the obstacle, the first extension wing 41 resets from the folded state to the unfolded state to provide support for the cargo.

[0053] In some embodiments, the first support device 4 includes a pivot 44 and a base 43 fixed to the first fork 2. The pivot 44 passes through the base 43, the first reset mechanism 42 and the first extension wing 41, and fixes the base 43, the first reset mechanism 42 and the first extension wing 41.

[0054] like Figure 5 As shown, the base 43 is fixed to the outer surface of the first fork 2, and the end of the first extension wing 41 adjacent to the first fork 2 is hinged to the base 43 through the pivot 44.

[0055] The first reset mechanism 42 includes a second torsion arm 4212 and a fourth torsion arm 4222. The first extension wing 41 is provided with a first insertion hole 41a and a second insertion hole 41b. The second torsion arm 4212 is inserted into the second insertion hole 41b, and the fourth torsion arm 4222 is inserted into the first insertion hole 41a. The first insertion hole 41a and the second insertion hole 41b are located at one end of the first extension wing 41 adjacent to the first fork 2, and the extending directions of the first insertion hole 41a and the second insertion hole 41b are perpendicular to the pivot 44. The second torsion arm 4212 and the fourth torsion arm 4222 act on the first extension wing 41 through the first insertion hole 41a and the second insertion hole 41b.

[0056] The first socket 41a and the second socket 41b respectively constrain the fourth torsion arm 4222 and the second torsion arm 4212, reducing the displacement or shaking of the second torsion arm 4212 and the fourth torsion arm 4222 during use, thereby improving the reliability of the equipment.

[0057] The first reset mechanism 42 includes a first torsion arm 4211 and a third torsion arm 4221; the base 43 includes a first recess 431 and a second recess 432. The first torsion arm 4211 is disposed in the first recess 431 and fixed to the base 43. The third torsion arm 4221 is disposed in the second recess 432 and fixed to the base 43. The first torsion arm 4211 and the third torsion arm 4221 act on the base 43. The first torsion arm 4211 is subjected to a first force from the base 43, and the second torsion arm 4212 is subjected to a second force from the first extension wing 41. The first force and the second force form a torque. The third torsion arm 4221 is subjected to a third force from the first extension wing 41, and the fourth torsion arm 4222 is subjected to a fourth force from the base 43. The third force and the fourth force form a torque.

[0058] The first reset mechanism 42 includes a first fixing block 423 and a second fixing block 424 fixed to the base 43, wherein the first fixing block 423 is used to fix the first torsion arm 4211 and the second fixing block 424 is used to fix the third torsion arm 4221.

[0059] The first fixing block 423 and the second fixing block 424 respectively constrain the first torsion arm 4211 and the third torsion arm 4221, preventing the first torsion arm 4211 and the third torsion arm 4221 from shifting or shaking during use, thereby improving the reliability of the equipment.

[0060] In some embodiments, such as Figure 3 As shown, the first reset mechanism 42 includes a first elastic element 421 and a second elastic element 422. In some embodiments, the first elastic element 421 and the second spring 422 are configured to jointly provide a restoring force to the first extension wing 41 when it rotates to the deployed state. When the first extension wing 41 is in the deployed state, the torque generated by the first elastic element 421 and the second elastic element 422 acting on the first extension wing 41 is zero; when the first extension wing 41 rotates in the first direction X or the second direction, the torque of the second elastic element 422 acting on the first extension wing 41 is in the same direction as that of the first elastic element 421, and the combined action of the two causes the first extension wing 41 to generate a torque to reset to the deployed state.

[0061] In some embodiments, the first elastic member 421 is configured to provide a restoring force for the first extension wing 41 to rotate in the first direction X, and the second elastic member 422 is configured to provide a restoring force for the first extension wing 41 to rotate in the second direction. The torques generated by the first elastic member 421 and the second elastic member 422 acting on the first extension wing 41 are in opposite directions, and the magnitudes of the torques satisfy: when the first extension wing 41 is in the unfolded state, the torques generated by the first elastic member 421 and the second elastic member 422 acting on the first extension wing 41 are equal in magnitude and thus cancel each other out; when the first extension wing 41 rotates in the first direction X, the torque generated by the second elastic member 422 acting on the first extension wing 41 is greater than the torque generated by the first elastic member 421; and when the first extension wing 41 rotates in the second direction, the torque generated by the first elastic member 421 acting on the first extension wing 41 is greater than the torque generated by the second elastic member 422.

[0062] Thus, when an external force acts on the first extension wing 41 to change it from the unfolded state to the folded state, after the external force disappears, the first extension wing 41 will eventually return to the unfolded state under the combined action of the first elastic member 421 and the second elastic member 422.

[0063] In this way, when the first extension wing 41 encounters an obstacle during use of the forklift, the first extension wing 41 can be rotated to the folded state to pass through the obstacle, so that the first fork 2 can smoothly travel in the first or second direction. At the same time, the risk of damage caused by scratching of the first extension wing 41 is reduced, and the service life of the equipment is increased.

[0064] In some embodiments, the first elastic member 421 is a torsion spring sleeved on the rotating shaft 44.

[0065] The first elastic member 421 includes a first spring body 4210, and a first torsion arm 4211 and a second torsion arm 4212 located at two ends of the first spring body 4210.

[0066] In some embodiments, the second elastic member 422 is a torsion spring sleeved on the rotating shaft 44, and the second elastic member 422 includes a second spring body 4220, and a third torsion arm 4221 and a fourth torsion arm 4222 located at two ends of the second spring body 4220.

[0067] During rotation of the first extension wing 41 from the unfolded state to the first direction X, the second spring body 4220 stores energy, the first spring body 4210 releases energy, and the torque generated by the fourth torsion arm 4222 acting on the first extension wing 41 is greater than the torque generated by the second torsion arm 4212. After the external force disappears, the first extension wing 41 returns to the unfolded state under the action of the fourth torsion arm 4222. When the first extension wing 41 rotates from the unfolded state to the second direction, the first spring body 4220 stores energy, the first spring body 4210 releases energy, and the torque generated by the second torsion arm 4212 acting on the first extension wing 41 is greater than the torque generated by the fourth torsion arm 4222. After the external force disappears, the first extension wing 41 returns to the unfolded state under the action of the second torsion arm 4212.

[0068] In some embodiments, multiple first support devices 4 are distributed along the extension direction of the first fork 2, which increases the force points in contact with the goods, making the goods more stable during transportation, and disperses the gravity of the goods to each first support device 4, reducing the stress on a single first device 4 and prolonging its service life.

[0069] In some embodiments, as shown in Figure 2 and Figure 3 , the forklift includes a second support device 6 fixed to the second fork 3, which has the same structure as the first support device 4.

[0070] As shown in Figure 2 , the second support device 6 is arranged on the outer side of the second fork 3. As shown in Figure 8 , the second support device 6 includes a second extension fin 61 that protrudes outward from the surface of the second fork 3, and the second extension fin 61 is configured to support external objects arranged on the second fork 2.

[0071] In some embodiments, as shown in Figure 2 , the second support device 6 is mirror-symmetric to the first support device 4, and the central axis O between the first fork 2 and the second fork 3 is located in the mirror-symmetric plane.

[0072] In this way, the second support device 6 and the first support device 4 are arranged on the outer side of the first fork 2 and the second fork 3, respectively, increasing the effective area of the mast 100b carrying the goods and improving the reliability of the forklift transporting the goods.

[0073] Another embodiment of the present application discloses a goods transportation assembly, as shown in Figure 6 , which includes the forklift and the pallet 5 in the above embodiments. As shown in Figure 7 and Figure 8 , the pallet 5 includes a bottom and a side, and the bottom of the pallet 5 is provided with a first recess 51 and a second recess 52 for inserting the first fork 2 and the second fork 3, respectively, and the side of the pallet 5 is provided with a first opening 53 communicating with the first recess 51, and the first extension fin 41 can enter the first opening 53.

[0074] The first extension fin 41 is configured to be in a folded state when located in the first recess 51 and reset to an unfolded state when entering the first opening 53.

[0075] In some embodiments, the first opening 53 and the outside of the pallet 5 are in communication, and the operator can observe whether the first extension fin 41 returns to normal through the first opening 53.

[0076] As shown in Figure 7 and Figure 8As shown, the first groove 51 and the second groove 52 extend along the first direction X, and the first opening 53 communicates with the first groove 51 in a direction perpendicular to the first groove 51. Figure 4 As shown, when the first fork 2 enters the first groove 51, the first extension wing 41, under the action of the inner wall of the first groove 51, rotates from the unfolded state to the second direction, thereby rotating to the folded state, so that the first fork 2 can continue to be pushed into the first groove 51. Figure 7 and Figure 8 As shown, when the first extension wing 41 moves to the first opening 53, the external force applied to the first extension wing 41 by the inner wall of the first groove 51 disappears, and the first extension wing 41 returns to its extended state within the first opening 53.

[0077] like Figure 9 As shown, when the first fork 2 exits from the first groove 51, the first extension wing 41, under the action of the inner wall of the first groove 51, rotates from the unfolded state to the first direction X, thereby rotating to the folded state, so that the first fork 2 can exit the first groove 51. When the first extension wing 41 moves out of the first groove 51, the external force applied to the first extension wing 41 by the inner wall of the first groove 51 disappears, and the first extension wing 41 returns to the extended state outside the first groove 51.

[0078] The first extension wing 41 supports the portion of the pallet 5 that extends beyond the first fork 2, making the force on the pallet 5 more balanced, reducing the risk of the pallet 5 tilting or tipping over, improving the reliability of forklift handling, and reducing operational difficulty. When the pallet 5 tilts due to external force, the first extension wing 41 interacts with the first opening 53 to support the pallet 5, further enhancing the overall stability of the handling assembly.

[0079] In some embodiments, such as Figure 10 As shown, the first extension wing 41 includes a first fixed end 41c connected to the first fork 2 and a first free end 41d opposite to the first fixed end 41c. The length between the first fixed end 41c and the first free end 41d is h1, as shown. Figure 2 As shown, the width of the first fork 2 from the inner side to the outer side is d1, as... Figure 7 As shown, the width of the first groove 51 is w1, which satisfies: h1+d1>w1.

[0080] After the first extension wing 41 enters the first groove 51, when the first extension wing 41 moves to the first opening 53, it can be reset from the folded state to the unfolded state, thereby entering the first opening 53 to lock the pallet 5 and reduce the risk of the pallet 5 falling off the forklift.

[0081] The side of the tray 5 is provided with a second opening 54 that connects to the second groove 3, and the second extension wing 61 can enter the second opening 54.

[0082] The second extension fin 61 is configured to be in a folded state when located in the second groove 52, and to reset to an unfolded state when entering the second opening 54.

[0083] As the first fork 2 and the second fork 3 enter the first groove 51 and the second groove 52 respectively, the first extension fin 41 enters the first opening 53, and the second extension fin 61 can enter the second opening 54, thereby increasing the effective range of the mast 100b for carrying the pallet 5. The first extension fin 41 cooperates with the first opening 53, and the second extension fin 61 cooperates with the second opening 54, thereby supporting the pallet 5 from two directions and improving the reliability of the forklift in transporting goods.

[0084] As shown in Figure 11 , the second extension fin 61 includes a second fixed end 61c connected to the second fork 3 and a second free end 61d opposite the second fixed end 61c, and the length between the second fixed end 61c and the second free end 61d is h2, as shown in Figure 2 , the width between the inner side and the outer side of the first fork 2 is d2, as shown in Figure 7 , the width of the second groove 52 is w2, and h2+d2>w2 is satisfied.

[0085] After the second extension fin 61 enters the second groove 52, when the second extension fin 61 moves to the second opening 54, it can reset from the folded state to the unfolded state, thereby entering the second opening 54 and achieving locking of the pallet 5, thereby reducing the risk of the pallet 5 separating from the forklift.

[0086] In some embodiments, as shown in Figure 2 and Figure 6 , a plurality of first extension fins 41 are arranged on the outer side of the first fork 2 along the first direction X, and a plurality of first openings 53 are arranged on the side of the pallet 5 along the first direction X corresponding to the first extension fins 41.

[0087] Through the one-to-one correspondence between the plurality of first extension fins 41 and the first openings 53, the locking ability of the forklift on the pallet 5 is improved, and the risk of the pallet 5 separating from the forklift is reduced.

[0088] In some embodiments, as shown in Figure 2 and Figure 8 , a plurality of second extension fins 61 are arranged on the outer side of the second fork 3 along the first direction X, and a plurality of second openings 54 are arranged on the other side of the pallet 5 along the first direction X corresponding to the second extension fins 61.
