[0037] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. Based on the embodiments in the embodiments, it is intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0038] As used herein, the phrase "in one embodiment" or "example" or "instance" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment disclosed in this application. The appearances of the phrase "in one embodiment" in various positions in the specification do not necessarily refer to the same embodiment.

[0039] As a first aspect of the present utility model, a lifting mechanism is provided. As shown in Figure 1 , the lifting mechanism includes a top plate 100, a scissor assembly, and a driving component 300. The scissor assembly is disposed on the back surface of the top plate 100, and the scissor assembly includes a plurality of scissor structures 210 arranged at intervals in a first set direction D1. The sliders ( Figure 1 two sliders 213 and two sliders 214 are shown in

[0040] ) of the plurality of scissor structures 210 are located on the same side of the scissor assembly. The sliders are capable of sliding along a second set direction D2, and the first set direction D1 intersects the second set direction D2.

[0041] Among them, the driving component 300 includes a lifting power source 310 and a crank and connecting rod sub - assembly 320. The lifting power source 310 is used to be fixed on the mounting base 400. The input end of the crank and connecting rod sub - assembly 320 is fixedly connected to the output shaft of the lifting power source 310. The output end of the crank and connecting rod sub - assembly 320 is hinged to the back surface of the top plate 100, and the driving component 300 is located on the slider side of the top plate 100.

[0042] In the embodiment of the present utility model, the driving assembly 300 is located on the slider side. The crank and connecting rod sub-assembly 320 can support the top plate 100 on the slider side, improving the stability when the lifting mechanism carries materials. Moreover, after the driving assembly is arranged on the slider side of the top plate 100, it is beneficial to set corresponding functional modules in the area corresponding to the hinge point side of the top plate 100 on the installation base 400, improving the space utilization rate of the equipment including the installation base 400.

[0043] In the embodiment of the present utility model, no special limitation is imposed on the specific type of the installation base 400, as long as it is a part of the equipment that needs to be provided with a lifting mechanism. For example, the installation base 400 can be the chassis of a transport vehicle. For another example, the installation base 400 can also be any one of the following mechanisms: the mounting seat of a material transfer device, a part of a material buffer device, and a part of a material transfer device.

[0044] That is to say, the lifting mechanism provided by the embodiment of the present utility model can be used in any of the following equipment: transport vehicles, material transfer devices, material buffer devices, and material transfer devices.

[0045] It should be noted that when the lifting mechanism provided by the embodiment of the present utility model is used in a transport vehicle, the installation base 400 is the chassis of the transport vehicle, and the slider side of the top plate 100 faces the rear of the chassis. Structures such as a navigation module and a caster module are arranged in the front area of the chassis of the transport vehicle. Therefore, the space in the front area of the chassis of the transport vehicle is limited. In the embodiment of the present utility model, the overall layout of the driving assembly 300 on the lifting mechanism is close to the slider side, without occupying the front area of the chassis, and more reasonably utilizes the space of the chassis.

[0046] The "crank and connecting rod sub-assembly" utilizes the basic working principle of "crank and connecting rod", that is, it can convert rotational motion into reciprocating motion. The lifting power source 310 of the driving assembly 300 is arranged on the installation base 400, and the output end of the crank and connecting rod sub-assembly is arranged on the top plate 100. The lifting power source 310 outputs rotational motion, which is converted by the crank and connecting rod sub-assembly into reciprocating motion for the top plate 100 to move towards or away from the installation base 400, thereby driving the scissor assembly to lift and lower. The lifting force output by the crank and connecting rod sub-assembly 320 acts directly on the top plate 100, rather than on the slider of the scissor mechanism. That is to say, during the lifting and lowering process of the scissor assembly, the lifting force no longer passes through the scissor structure 210, thereby realizing load sharing, greatly reducing the internal load of the scissor assembly, improving the strength of the scissor assembly, and extending the service life of the scissor assembly.

[0047] Specifically, the torque and rotation angle output by the jacking power source 310 are converted by the crank and connecting rod subassembly 320 into a bearing capacity for supporting the gravity load on the top plate 100, and the rotation angle is converted by the crank and connecting rod subassembly 320 into a displacement for driving the position control of the assembly 300.

[0048] Figure 6 is Figure 1 a schematic diagram of the load parallel sharing structure of the jacking mechanism provided in. As Figure 6 shown, since the crank and connecting rod subassembly is directly connected to the top plate 100, the driving assembly and the scissor assembly are connected in parallel to respectively bear the gravity load and the eccentric load moment in the external load.

[0049] As an alternative embodiment, the first direction D1 and the second direction D2 are perpendicular to each other. Optionally, the second direction D2 may be the length direction of the jacking mechanism, and the first direction D1 may be the width direction of the jacking mechanism.

[0050] In the embodiment of the present utility model, each scissor structure 210 has a plurality of sliders. It is easy to understand that at least one of the plurality of sliders of the scissor structure 210 ( Figure 1 the slider 214 in) is slidably disposed on the back surface of the top plate 100, and at least another one of the plurality of sliders of the scissor structure 210 ( Figure 1 the slider 213 in) is used to be slidably disposed on the mounting base 400. In order to make the top plate 100 more stable during the lifting process, optionally, the output end of the crank and connecting rod subassembly 320 is disposed between the moving paths of two adjacent sliders 214 located on the top plate 100. Further, the distance between the output end of the crank and connecting rod subassembly 320 and the moving paths of the two adjacent sliders to the crank and connecting rod subassembly 320 is the same. As Figure 3 shown, the moving path of the slider 213 is represented by S1, and the moving path of the slider 214 is represented by S2. The output end of the crank and connecting rod subassembly 320 is hinged to the top plate 100 through a hinge seat 323. Therefore, the distance L1 between the hinge seat 323 and the moving path S1 is the same as the distance L2 between the hinge seat 323 and the moving path S2. It should be noted that the "same" here means approximately the same, allowing for machining errors.

[0051] It should be noted that the embodiment of the present utility model is not limited thereto. The output end of the crank and connecting rod subassembly may be located outside the moving paths of the two sliders. For example, the output end of the crank and connecting rod subassembly 320 may be disposed outside the outermost slider 214 on the top plate. For another example, the output end of the crank and connecting rod subassembly 320 may also be disposed at the edge of the top plate 100.

[0052] As Figure 2 and Figure 3As shown, the output end of the crank - connecting rod sub - assembly 320 is hinged to the top plate 100 through the hinge seat 323.

[0053] In the embodiment of the present utility model, no special limitation is imposed on the specific number of the scissor structures 210 in the scissor assembly. For example, in Figure 1 the embodiment shown, the scissor assembly includes two scissor structures 210.

[0054] In the embodiment of the present utility model, no special limitation is imposed on the specific composition of the scissor structure 210. As Figure 1 shown, the scissor structure 210 further includes a first slider rod 211 and a second slider rod 212, and corresponding sliders are provided for both the first slider rod 211 and the second slider rod 212. In Figure 1 the specific embodiment shown, the first slider rod 211 corresponds to the slider 213, and the second slider rod 212 corresponds to the slider 214.

[0055] The slider 213 corresponding to the first slider rod 211 is used to be slidably arranged on the mounting base 400, the slider 214 corresponding to the second slider rod 212 is slidably arranged on the back surface of the top plate 100. The middle part of the first slider rod 211 is hinged to the middle part of the second slider rod 212. The first end of the first slider rod 211 is hinged to the back surface of the top plate 100. The second end of the first slider rod 211 is hinged to the slider 213 corresponding to this first slider rod 211. The first end of the second slider rod 212 is used to be hinged to the mounting base 400, and the second end of the second slider rod 212 is hinged to the slider 214 corresponding to this second slider rod 212.

[0056] When the output end of the crank - connecting rod sub - mechanism 320 rises, the top plate 100 is lifted. Correspondingly, the slider 213 of the scissor structure 210 moves towards the first end of the second slider rod 212, and the slider 214 of the scissor structure 210 moves towards the first end of the first slider rod 211.

[0057] When the output end of the crank - connecting rod sub - assembly 320 descends, the top plate 100 is pulled down. Correspondingly, the slider 213 of the scissor structure 210 moves away from the first end of the second slider rod 212, and the slider 214 of the scissor structure 210 moves away from the first end of the first slider rod 211.

[0058] To improve the overall stability of the scissor assembly, optionally, the scissor assembly may further include a connecting shaft 220 and at least one support seat 230. The first ends of a plurality of second slider rods 212 are hinged to the support seat 230 through the connecting shaft 220, and the support seat 230 is used to be arranged on the mounting base 400.

[0059] Multiple scissor structures 210 can be connected into a whole through a connecting shaft 220, so that the scissor assembly including multiple scissor structures 210 has higher structural stability, thereby improving the stability during the process of lifting materials.

[0060] In the embodiment of the present utility model, there is no special limitation on how to slidably arrange the slider on the top plate 100 or the mounting base 400. As an optional implementation manner, a dovetail groove can be arranged on the back surface of the top plate 100, and the corresponding slider 214 can be arranged as a dovetail-shaped slider matching the dovetail groove. Similarly, a dovetail groove can also be arranged on the surface of the mounting base, and the corresponding slider 213 can be arranged as a dovetail-shaped slider matching the dovetail groove.

[0061] For the convenience of processing and assembly, optionally, the scissor structure 210 further includes a plurality of chute members corresponding to the plurality of sliders one by one. The chute member has a slider opening, and the slider is arranged in the sliding groove of the corresponding chute member through the slider opening.

[0062] As Figure 1 shown in, the chute member 214a corresponding to the slider (not shown) on the top plate 100 is fixedly arranged on the back surface of the top plate 100, so that the corresponding slider slides along the sliding groove of the chute member 214a.

[0063] Similarly, the chute member 213a corresponding to the slider 213 for being arranged on the mounting base 400 is used for being fixedly arranged on the mounting base 400, so that the corresponding slider 213 slides along the sliding groove of the chute member 213a.

[0064] It is easy to understand that the top wall of the chute member is oppositely arranged to the bottom wall of the chute member. For improving the stability during the sliding process of the slider, optionally, the chute member can further include side plates connected between the top wall and the bottom wall of the chute member. During the sliding process of the slider, the top wall, the bottom wall, and the side plates of the chute member can limit and guide the slider. For ensuring that the slider can move within a set range, optionally, the chute member can further include two oppositely arranged end plates, and both end plates are connected between the top wall and the bottom wall of the chute member.

[0065] As Figure 3 shown in, the chute members 213a and 214a on the back surface of the top plate 100 are arranged at intervals, and the side plates of the chute member 213a are opposite to the side plates of the chute member 214a.

[0066] In the embodiment of the present utility model, there is no special limitation on the specific structure of the crank and connecting rod subassembly 320, as long as the rotary motion can be converted into reciprocating motion through the crank and connecting rod principle.

[0067] AsFigure 5 As shown, the crank - connecting rod sub - assembly 320 may include a first swing arm 321 and a second swing arm 322. The first end of the first swing arm 321 is formed as the input end of the crank - connecting rod sub - assembly 320 and is fixedly connected to the output shaft of the lifting power source (see Figure 4 the output shaft 310a in). The second end of the first swing arm 321 is hinged to the first end of the second swing arm 322. The second end of the second swing arm 322 is formed as the output end of the crank - connecting rod sub - assembly 320 and is hinged to the back surface of the top plate 100.

[0068] Figure 2 On the left side in, it is the lowest state of the scissor assembly. The first swing arm 321 is vertical, and the second end of the first swing arm 321 faces the mounting base 400. Driven by the lifting power source 310, the first swing arm 321 rotates clockwise around the output shaft of the lifting power source 310 until the first swing arm 321 is vertical and the second end of the first swing arm 321 faces the top plate 100, and the scissor assembly rises to the highest state.

[0069] In the embodiment of the present utility model, there are no special limitations on the length of the first swing arm 321 and the length of the second swing arm 322. Optionally, the length of the first swing arm 321 is between one - third and one - half of the length of the second swing arm 322.

[0070] As an alternative implementation manner, the first swing arm 321 and the second swing arm 322 are hinged through a spherical plain bearing.

[0071] In the embodiment of the present utility model, there are also no special limitations on the specific structure of the lifting power source 310, as long as it can output torque. As an alternative implementation manner, as Figure 4 shown, the lifting power source 310 includes a motor 311 and a reduction assembly 312. The output shaft 310a of the reduction assembly 312 is the output shaft of the lifting power source 310. The motor 311 outputs torque and rotation angle, and the reduction assembly 312 is used to match the power requirements of the end (i.e., the crank - connecting rod sub - assembly) to achieve the power output function.

[0072] Specifically, the first swing arm 321 is connected to the output shaft 310a of the reduction assembly 312. The second end of the first swing arm 321 passes above the spherical plain bearing of the second swing arm 322 and is hinged to the second swing arm 322.

[0073] In the present utility model, the hinge point of the second swing arm 322 of the crank - connecting rod sub - assembly 320 (i.e., the output end of the crank - connecting rod sub - assembly) is close to the slider. Then the driving assembly is also located on the slider side, realizing the power rear - position. Compared with the scheme of arranging the driving assembly on the hinge - point side, the embodiment of the present utility model can directly reuse the hinge - point and slider connection features of the chassis, avoiding re - developing the chassis or developing an adapter for connecting the scissor assembly, and having better compatibility.

[0074] As the second aspect of the present utility model, a material handling device is provided. The material handling device includes an installation base 400 and a jacking mechanism. Among them, the jacking mechanism is the jacking mechanism provided in the first aspect of the present utility model, and the top plate 100 is disposed opposite to the installation base 400.

[0075] As described above, the drive assembly 300 is located on the slider side. The crank and connecting rod sub-assembly 320 can support the top plate 100 on the slider side, improving the stability of the jacking mechanism when carrying materials. Moreover, after the drive assembly is arranged on the slider side of the top plate 100, it is beneficial to set corresponding functional modules in the area corresponding to the hinge point side of the top plate 100 on the installation base 400, improving the space utilization rate of the device including the installation base 400.

[0076] It should be noted that "material handling" here refers to actions related to transporting materials, transferring materials, and storing materials.

[0077] In the embodiment of the present utility model, the material handling device can be any one of a transport vehicle, a material transfer device, a material buffer device, and a material transfer device.

[0078] As an alternative embodiment, the material handling device is a transport vehicle, and the chassis of the transport vehicle serves as the installation base 400.

[0079] Correspondingly, the slider side of the top plate 100 faces the rear of the installation base 400 (i.e., the chassis). Structures such as a navigation module and a caster module are provided in the front area of the installation base 400 of the transport vehicle. Therefore, the space in the front area of the installation base 400 of the transport vehicle is limited. In the embodiment of the present utility model, the overall layout of the drive assembly 300 on the jacking mechanism is rearward, without occupying the front area of the installation base 400, making more reasonable use of the space of the installation base 400.

[0080] As an alternative embodiment, the transport vehicle includes a navigation module, and the navigation module is disposed on the chassis and located at the front of the chassis.

[0081] As an alternative embodiment, when the scissor assembly is in the lowest position, the top plate 100 is not lower than the top surface of the housing of the chassis (i.e., the installation base 400).

[0082] The above is only the specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that the present utility model includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present utility model will be included in the scope of the claims.
