[0055] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0056] To achieve the above objectives, the technical solution of this utility model is as follows:

[0057] See Figures 1-8As shown, this utility model provides a lifting structure, including: a support plate 10, disposed on the body 1; a lifting component 20, movably disposed on the support plate 10; and a steering component 30, connected to the lifting component 20; the lifting component 20 is used to drive the steering component 30 to move vertically relative to the support plate 10; and the steering component 30 is used to rotate vertically relative to the lifting component 20, the support plate 10, and the body 1.

[0058] The lifting structure provided by this utility model is fixedly installed on the body 1 via a support plate 10. A lifting component 20 is movably disposed on the support plate 10. The lifting component 20 moves vertically relative to the support plate 10. A steering component 30 is connected to the lifting component 20. Thus, when the lifting component 20 moves vertically upward relative to the support plate 10, it drives the steering component 30 to move vertically upward relative to the support plate 10, reducing the distance between the steering component 30 and the support plate 10 and the body 1, thereby reducing the overall height of the lifting structure. Conversely, when the lifting component 20 moves vertically downward relative to the support plate 10, it drives the steering component 30 to move vertically downward relative to the support plate 10, increasing the distance between the steering component 30 and the support plate 10 and the body 1, thereby increasing the overall height of the lifting structure. Therefore, this lifting structure can be designed to be raised and lowered relative to the support plate 10 via the lifting component 20 and the steering component 30, achieving overall height adjustment. Furthermore, through the connection between the steering component 30 and the lifting component 20, the steering component 30 is used to rotate vertically relative to the lifting component 20, the support plate 10, and the body 1, enabling the lifting structure to be steered via the steering component 30. Therefore, the lifting structure can adapt to the needs of placing goods at different heights, and the lifting structure is easy to turn and move.

[0059] Furthermore, the support plate 10 includes a front end 11 and a rear end 12; the lifting assembly 20 is provided in at least two sets; some of the lifting assemblies 20 are respectively arranged on both sides of the rear end 12; the remaining lifting assemblies 20 are respectively arranged on both sides of the front end 11. By providing at least two sets of lifting assemblies 20 and at least two sets of steering assemblies 30, the lifting structure can be suitable for scenarios involving climbing at least one step, and the lifting structure can be adapted to different overall height adjustment needs. The overall height adjustment of the lifting structure can be achieved through the two sets of lifting assemblies 20 and the steering assemblies 30.

[0060] Further, the lifting assembly 20 includes a first gear 22 and a first drive assembly 23. The first gear 22 is disposed on the side of the support plate 10 near the steering assembly 30, with one side of the first gear 22 spaced apart from or in contact with the support plate 10, and the other side of the first gear 22 in contact with the steering assembly 30. The first drive assembly 23 is disposed on the side of the first gear 22 away from the steering assembly 30, and the first drive assembly 23 passes through the first gear 22 and is connected to the steering assembly 30. The first drive assembly 23 is used to drive the steering assembly 30 to move vertically relative to the support plate 10.

[0061] It should be noted that the first drive assembly 23 passes through the first gear 22 and connects to the steering assembly 30. The first drive assembly 23 can drive the first gear 22 and the steering assembly 30 to move vertically upwards or downwards. Therefore, when the vertical height of the lifting structure needs to be adjusted to decrease or increase, the first drive assembly 23 needs to be activated first. After the first drive assembly 23 is activated, it drives the first gear 22 and the steering assembly 30 to move vertically relative to the support plate 10, thereby achieving vertical height adjustment of the entire lifting structure.

[0062] Further, the first drive assembly 23 includes a first motor 24, a second gear 25, a third gear 26, and a first lead screw 27. The first motor 24, the second gear 25, and the third gear 26 are disposed on the side of the support plate 10 away from the first gear 22. The third gear 26 and the first gear 22 are vertically spaced apart, and the second gear 25 and the first gear 22 are also vertically spaced apart. The second gear 25 is connected to the first motor 24. Specifically, the second gear 25 is axially connected to the output shaft of the first motor 24, which extends vertically. The axial direction of the second gear 25 is aligned with the vertical direction, and the first motor 24 drives the second gear 25 to rotate vertically around its axial direction. The third gear 26 is drively connected to the second gear 25. Specifically, the axial direction of the third gear 26 is vertical, and the third gear 26 and the second gear 25 are connected via a conveyor belt, allowing the third gear 26 and the second gear 25 to rotate synchronously around their respective axial directions. The first lead screw 27 is connected between the third gear 26 and the steering assembly 30. Specifically, the third gear 26 is axially connected to one end of the first lead screw 27, and the other end of the first lead screw 27 passes through the first gear 22 and is connected to the steering assembly 30. This end of the first lead screw 27 is rotatably connected to the steering assembly 30 about vertically. By allowing the steering assembly 30 to rotate vertically relative to the first lead screw 27, the design requirement that the steering assembly 30 can rotate relative to the lifting assembly 20, the support plate 10, and the main body 1 is met.

[0063] Furthermore, the lifting assembly 20 also includes a first mounting plate 201 and a second mounting plate 202. The first mounting plate 201 is disposed between the first gear 22 on the side away from the steering assembly 30 and the support plate 10. The second mounting plate 202 is disposed on the side of the support plate 10 away from the first mounting plate 201. The second mounting plate 202, the support plate 10, and the first mounting plate 201 are arranged sequentially in a vertical direction. The first gear 22 is fixedly mounted on the side of the first mounting plate 201 away from the support plate 10, and the first gear 22 is fastened to the first mounting plate 201 by screws. The first motor 24 is fixedly mounted on the second mounting plate 202. The second gear 25 and the third gear 26 are fixedly mounted on the side of the second mounting plate 202 away from the first mounting plate 201. The second gear 25 and the third gear 26 can rotate about their own axial direction on the second mounting plate 202, thereby enabling synchronous vertical transmission on the second mounting plate 202. One end of the first lead screw 27 passes through the second mounting plate 202 and is connected to the third gear 26. The other end of the first lead screw 27 passes through the first mounting plate 201 and the first gear 22 and is connected to the steering assembly 30. The first lead screw 27 is axially rotatably connected to the first mounting plate 201 through a bearing. The bearing is axially adapted to the interior of the first mounting plate 201. The bearing is designed to enable the first lead screw 27 to rotate vertically relative to the first mounting plate 201.

[0064] Furthermore, the support plate 10 is provided with a guide 203, which is fixedly installed on the support plate 10 along the axial direction. The guide 203 is provided with a mating hole that penetrates the support plate 10. The first lead screw 27 penetrates the mating hole of the guide 203. The outer peripheral surface of the first lead screw 27 mates with the inner peripheral surface of the mating hole of the guide 203. The guide 203 is used to provide vertical guidance for the movement of the first lead screw 27.

[0065] Furthermore, the lifting assembly 20 also includes multiple guide rods 204; the guide rods 204 are spaced apart around the first lead screw 27, and extend vertically between the first mounting plate 201 and the support plate 10, and extend vertically between the support plate 10 and the second mounting plate 202. Through the position and structural design of the multiple guide rods 204, when the first drive assembly 23 drives the second mounting plate 202 and the first mounting plate 201 to move vertically relative to the support plate 10, the guide rods 204 move vertically together with the second mounting plate 202 or the first mounting plate 201, so as to play a role in vertical guidance.

[0066] Further, the steering assembly 30 includes: a mounting housing 31 and a first rotating wheel 32. The mounting housing 31 is disposed on the side of the first gear 22 away from the first mounting plate 201. One end of the first lead screw 27 passes through the first mounting plate 201 and the first gear 22 and is rotatably connected to the mounting housing 31. The mounting housing 31 can rotate vertically relative to the first mounting plate 201 and the first gear 22. Preferably, the end of the first lead screw 27 is connected to the mounting housing 31 through a bearing, and the bearing is fitted inside the mounting housing 31. Each set of steering assemblies 30 is provided with two first rotating wheels 21, which are symmetrically distributed on both sides of the mounting housing 31. The two first rotating wheels 21 are connected by a shaft passing through the mounting housing 31 to achieve stable movement of the first rotating wheels 21.

[0067] Furthermore, the steering assembly 30 also includes a second motor 33 and a fourth gear 34. The second motor 33 is fixedly mounted on the mounting housing 31. The fourth gear 34 is connected between the first gear 22 and the second motor 33. Specifically, the output shaft of the second motor 33 extends vertically, and the fourth gear 34 is axially connected to the output shaft of the second motor 33. The axis of the fourth gear 34 is vertical, and the fourth gear 34 meshes with the first gear 22. The output shaft of the second motor 33 is used to drive the fourth gear 34 to rotate vertically. Since the fourth gear 34 is meshed and connected to the first gear 22, the outer gear of the fourth gear 34 rotates relative to the outer gear of the first gear 22. The fourth gear 34 drives the mounting shell 31 and the first rotating wheel 32 to turn relative to the first gear 22. That is, the fourth gear 34 drives the mounting shell 31 and the first rotating wheel 32 to turn relative to the support plate 10. At this time, the mounting shell 31 rotates relative to the first lead screw 27 through the built-in bearing. The mounting shell 31 drives the first rotating wheel 32 to turn relative to the support plate 10 in a vertical direction. This lifting structure realizes the function of turning in a vertical direction through the steering assembly 30.

[0068] Therefore, the lifting structure provided by this utility model drives the steering component 30 to move vertically relative to the support plate 10 through the lifting component 20, so that the overall height of the lifting structure can be adjusted vertically. The steering component 30 is connected to the lifting component 20 and is used to rotate relative to the lifting component 20, the support plate 10 and the body 1 around the vertical, so that the lifting structure can be turned through the steering component 30.

[0069] This utility model also provides a loading device suitable for loading materials inside a vehicle compartment 100. The compartment 100 includes at least one step 110. The loading device includes the aforementioned lifting structure and further includes: a main body 1, a feeding mechanism 2, and a fixed wheel set 3. A support plate 10 is disposed on the main body 1; the feeding mechanism 2 is disposed on the side of the main body 1 away from the lifting structure 20, and is used to provide loading for loading goods; the fixed wheel set 3 is disposed at the front end 11, and the fixed wheel set 20 rotates or rolls relative to the main body 1 to drive the main body 1 forward or backward, so that loading is convenient when the main body 10 moves forward and returning for material transport is convenient when the main body 10 moves backward.

[0070] Further, the feeding mechanism 2 includes: a feeding plate 201, a second drive assembly, a third drive assembly, a pusher plate 204, and a fourth drive assembly. The feeding plate 201 is used to carry pallets for loading goods, and is connected to the conveyor belt 4 above the housing 1 to receive materials. The second drive assembly is connected to the feeding plate 201 and is used to drive the feeding plate 201 to move along a first direction X. The second drive assembly includes a third motor 202, a synchronous pulley connected to the third motor 202, and a lead screw connected between the synchronous pulley and the feeding plate 201. The third motor 202 is used to drive the feeding plate 201 to move along the first direction X or in the opposite direction of the first direction X for loading goods. The third drive assembly is connected to the feeding plate 201 and is used to drive the feeding plate 201 to move along a second direction Y. The third drive assembly includes a fourth motor 203 and a synchronous belt connected to the fourth motor 203. The system includes a wheel, a lead screw connecting the synchronous pulley and the feeding plate 201, and a fourth motor 203 for driving the feeding plate 201 to move along the second direction Y or in the opposite direction of the second direction Y. A pusher plate 204 is correspondingly disposed on the side of the feeding plate 201 away from the body 1. A fourth drive assembly is connected to the pusher plate 204 and includes a fifth motor 205, multiple sets of synchronous pulleys connected to the fifth motor 205, and a lead screw connecting the synchronous pulleys and the pusher plate 204. The fifth motor 205 is used to drive the pusher plate 204 to move relative to the feeding plate 201 along the first direction X. The first direction X is the direction from the rear end 12 to the front end 11, and any two of the vertical, second, and first directions Y intersect perpendicularly. Preferably, there are two feeding plates 201, which are spaced apart along the second direction Y. Correspondingly, there are two pusher plates 204, which are slidably disposed on the feeding plates 201.

[0071] It should be noted that the lifting components and steering components 30 of the lifting structure are each provided with at least two sets. The loading device is suitable for scenarios where at least one step needs to be climbed. Furthermore, the lifting structure can be adapted to different height adjustment requirements. Thus, the lifting structure can meet the requirements for placing or loading goods at different heights. The loading objects can be different types of items such as rolls, rods, express boxes, and fertilizers.

[0072] The feeding device provided by this utility model includes a lifting structure, a main body 1, a feeding mechanism 2, and a fixed wheel set 3. The lifting component 20 of the lifting structure moves vertically relative to the support plate 10 and the main body 1, adjusting the overall height of the feeding device to decrease. When the lifting component 20 moves vertically downward relative to the main body 10, the overall height of the feeding device increases. Thus, the height adjustment design of the feeding device is achieved through the lifting design of the lifting component 20. Furthermore, the steering component 30 is used to turn the feeding device around the vertical relative to the support plate 10 and the main body 1, realizing the steering design of the feeding device. Therefore, this feeding device can meet the usage needs in different step scenarios and can also adapt to the needs of placing goods at different heights.

[0073] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
