Description

Technical Field

[0001] This invention relates to the field of tractor technology, and in particular to a tractor suitable for operation in multiple scenarios. Background Technology

[0002] A tractor unit is a specialized traction device used to tow or push goods, containers, or other types of vehicles. It is widely used in industries such as warehousing, sorting, airport baggage handling, production line logistics, rescue, cargo handling and transfer, and agriculture. Its applications are extensive and its working conditions are diverse. Different traction devices are required for different working conditions to adapt to the normal operation of the tractor unit under special working conditions.

[0003] Chinese patent CN211442351U discloses an electric tractor, characterized in that the electric tractor includes a rear axle motor, rear wheels and front wheels, a connecting frame, handlebars, a power supply box, and a ball joint. The ball joint is pulled out and connected to an external logistics trolley. The rear axle motor drives the rear wheels, and the external logistics trolley is moved by manually pulling the handlebars. This utility model has a simple structure and is easy to use; by driving the rear wheels with the rear axle motor, it greatly saves manpower.

[0004] However, this technical solution is applicable to only one working condition and cannot adjust the corresponding parameters or states according to different working conditions to adapt to the corresponding working conditions. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a tractor unit suitable for multi-scenario operation. By adjusting components to change the connection between the operating assembly and the vehicle body or front wheels, the tractor unit can adapt to different working conditions, enabling its application in multiple scenarios. Operators can flexibly adapt to different working conditions to achieve optimal operation. Furthermore, by setting a first and second rotation position on the wheel frame, the position of the front wheel's rotation axis and the operating assembly's rotation axis can be switched. Combined with the adjusting components, this further improves the smoothness of the tractor unit's operation. In particular, when the operating assembly is connected to the vehicle body, adjusting the front wheels to an eccentric state improves the vehicle's steering sensitivity and smoothness. Simultaneously, when the operating assembly is connected to the front wheel assembly, the front wheels and rotation axis are located in the same plane, improving steering accuracy and making it more suitable for operation in confined spaces. This solves the problem of existing tractor units having limited functionality and being unable to adapt to more working conditions.

The axis of the second rotating position is offset from the rotation axis of the operating assembly. The front wheel is rotatably mounted in the first rotating position or the second rotating position.

[0029] As an improvement, the wheel frame is provided with a track connecting the first rotation position and the second rotation position.

[0030] As an improvement, the front wheel assembly further includes a locking assembly, which is mounted at both ends of the rotating shaft and is used to fix the position of the front wheel at a first rotation position and a second rotation position.

[0031] As an improvement, the connector is provided with a first limiting groove, the upper end of the connecting flange is provided with a second limiting groove, and the adjusting block reciprocates between the first limiting groove and the second limiting groove to switch the connection mode between the operating assembly and the vehicle body or front wheel assembly.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0061] Example 1

[0062] like Figures 1-3 As shown, this embodiment provides a tractor applicable to multiple operating scenarios, including: a vehicle body 1; a control component 2, which controls the direction of travel of the vehicle body 1 and is located at the front of the vehicle body 1; a traction connection component 3, which is located at the rear of the vehicle body 1 and is used to connect to the object to be towed; a drive component 4, which drives the vehicle body 1 to move; the drive component 4 includes a rear wheel 41 rotatably mounted at the rear of the vehicle body 1 and a drive motor for driving the rear wheel 41 to rotate; and a control component 5, which is located on the vehicle body 1 and is used to control and process the signals given by the control component 2 and output them to the drive component 4, so that the drive component 4 drives the vehicle body 1 forward or backward; preferably, the control component 5 is located in the middle of the vehicle body 1.

[0063] The control assembly 2 includes: a connector 21 detachably connected to the vehicle body 1; an operation assembly 22 rotatably mounted on the connector 21; a front wheel assembly 23 rotatably mounted below the connector 21; and an adjustment assembly 24 located below the operation assembly 22 for switching the operation assembly 22 to be integrated with the vehicle body 1 or integrated with the front wheel assembly 23, so that the operation assembly 22 directly controls the vehicle body 1 or directly controls the front wheel assembly 23.

[0064] Preferably, the operating assembly 22 includes a hinge seat 224, an operating lever 221 hinged to the hinge seat 224, and a control knob 222 on the operating lever 221 for controlling the movement of the tractor; the control knob 222 controls the tractor to move forward, backward, and other actions.

[0065] Preferably, a rotating shaft 223 is fixedly connected to the lower part of the hinge seat 224, and a support plate 225 is fixedly mounted on the rotating shaft 223, so that the support plate 225 rotates synchronously with the rotating shaft 223, and one end of the rotating shaft 223 passes through the support plate 225. Specifically, the support plate 225 can be fixedly connected to the rotating shaft 223 by welding, threaded connection, snap-fit, or other connection methods. Of course, it is not limited to the above connection methods. For example, the rotating shaft 223 and the support plate 225 can be integrally formed.

[0066] As an improvement, such as Figures 4-7 As shown, the adjustment component 24 includes:

[0067] A fixing plate 241 is connected to the bottom of the operating assembly 22. A first sliding groove 2411 is provided on the bottom of the fixing plate 241. Limiting protrusions 2412 and guide protrusions 2413 are respectively provided at both ends of the fixing plate 241. Specifically, the fixing plate 241 is installed on the support plate 225 by fasteners. A second sliding groove 2251 adapted to the first sliding groove 2411 is provided on the support plate 225.

[0068] An adjusting rod 242 is slidably disposed on the fixed plate 241 and passes through the limiting protrusion 2412 and the guide protrusion 2413. One end of the adjusting rod 242 is provided with a handle 243, which can both pull and rotate the adjusting rod and limit the position of the adjusting rod.

[0069] An adjusting block 244 is sleeved on the adjusting rod 242 and moves back and forth with the adjusting rod 242. Its lower end is slidably disposed in the first sliding groove 2411. Specifically, the adjusting rod 242 is provided with a limiting step 2421, and one end of the adjusting block 244 abuts against the limiting step 2421 and moves back and forth with the adjustment rod 242.

[0070] The limiting member 245 is installed at one end of the adjusting rod 242. The limiting protrusion 2412 has a slot, through which the limiting member 245 can pass and be rotated and locked at the edge of the slot.

[0071] The reset member 246 is sleeved on the adjusting rod 242 and is used to reset the adjusting block 244. Specifically, one end of the reset member 246 abuts against one side of the adjusting block 244, and the other end abuts against the side of the guide protrusion 2413.

[0072] It should be noted that, as Figure 7 As shown, by pulling the adjusting rod 242 to the right using the handle 243, the adjusting block 244 moves, and the limiting member 245 passes through the limiting protrusion 2412. Then, by rotating the adjusting rod 242, the limiting member 245 rotates 90° and locks onto the right side of the limiting protrusion 2412, thus fixing the position of the adjusting block 244. Under the action of the reset member 246, the limiting member 245 always abuts against the limiting protrusion 2412, achieving stable positioning. At this time, the adjusting block 244 engages with the first limiting groove 211, making the operating assembly 22 and the connecting member 21 engage as a single structure. That is, the operating assembly 22 is connected to the vehicle body 1 as a single structure. The vehicle body 1 is controlled to move by the operating assembly 22. When turning, the front wheel 233 at the bottom is a universal wheel structure. The traction vehicle's direction of travel is switched by controlling the left and right swing of the vehicle body 1 through the operating assembly 22.

[0073] like Figure 6 As shown, when it is necessary to switch the connection state, pull the limiting member 245 and rotate it so that the limiting member 245 is aligned with the slot. Under the action of the reset member 246, the adjusting block 244 drives the adjusting rod 242 to move to the left, so that the adjusting block 244 engages with the second limiting slot 2321, realizing the connection between the operating assembly 22 and the front wheel assembly 23 as an integral structure. The front wheel assembly 23 controls the rotation direction of the front wheel assembly 23 through the swing of the operating assembly 22, thereby changing the travel direction of the tractor.

[0074] Preferred, such as Figure 5 As shown, the connector 21 has a first limiting groove 211, the upper end of the connecting flange 232 has a second limiting groove 2321, and the adjusting block 244 reciprocates between the first limiting groove 211 and the second limiting groove 2321 to switch the connection mode between the operation assembly 22 and the vehicle body 1 or the front wheel assembly 23.

[0075] Specifically, when the adjusting block 244 engages with the first limiting groove 211, the operating assembly 22 is connected to the vehicle body 1; at this time, by swinging the operating assembly left and right, the rotation angle of the front wheel 233 is changed through the vehicle body 1, thereby realizing the adjustment of the tractor's travel direction. The tractor has a large turning radius and runs smoothly, making it particularly suitable for heavy-load, low-speed, and large-travel-space working conditions.

[0076] In addition, when the adjusting block 244 engages with the second limiting groove 2321, the operating assembly 22 is connected to the front wheel assembly 23. At this time, the swing direction of the front wheel 233 is controlled by the left and right swing of the operating assembly 22, thereby controlling the travel direction of the tractor. The tractor has a small turning radius and is more suitable for light load, small travel space and high travel speed.

[0077] Example 2

[0078] like Figure 2 , Figure 5 , Figure 9 , Figure 10 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0079] In this embodiment, as Figure 5 , Figure 9 As shown, the front wheel assembly 23 includes:

[0080] A connecting flange 232 is rotatably mounted inside the connecting member 21 via a bearing; the operating assembly 22 is rotatably connected inside the connecting flange 232 via a rotating shaft 223; specifically, a bearing is provided between the rotating shaft 223 and the inner wall of the connecting flange 232, so that the rotating shaft 223 can be rotatably mounted inside the connecting flange 232, and the connecting flange 232 can rotate, thereby driving the front wheel 233 to rotate.

[0081] Wheel frame 231, the wheel frame 231 is disposed at the bottom of the connecting flange 232;

[0082] The front wheel 233 is rotatably mounted on the wheel frame 231 via a rotating shaft.

[0083] Furthermore, such as Figure 10 As shown, the wheel frame 231 has a first rotating position 2311 and a second rotating position 2312 on its side. The axis of the first rotating position 2311 is located in the same plane as the rotation shaft 223 of the operating assembly 22. The axis of the second rotating position 2312 is offset from the rotation shaft 223 of the operating assembly 22. The front wheel 233 is rotatably mounted in the first rotating position 2311 or the second rotating position 2312.

[0084] It should be noted that the first rotation position 2311 and the second rotation position 2312 can be two independently set through holes used to fix the rotation shaft of the front wheel 233. When it is necessary to switch the position of the front wheel 233 in the above two rotation positions, the rotation shaft is pulled out and the front wheel 233 is installed in the other rotation position to complete the switching of the rotation position of the front wheel 233.

[0085] Furthermore, such as Figure 10As shown, the wheel frame 231 is provided with a track 2313 connecting the first rotation position 2311 and the second rotation position 2312, so that the rotation axis of the front wheel 233 can move quickly between the first rotation position 2311 and the second rotation position 2312 along the track 2313, thereby achieving efficient adjustment of the position of the front wheel 233. With the help of the locking buckle structure, the position of the front wheel 233 can be adjusted more efficiently and quickly.

[0086] Preferably, the first rotation position 2311 and the second rotation position 2312 are located at the same horizontal level, so that the rotation center of the front wheel remains unchanged after adjustment.

[0087] Preferably, the front wheel assembly 23 further includes a locking assembly 234, which is installed at both ends of the rotating shaft and is used to fix the front wheel 233 at the first rotating position 2311 or the second rotating position 2312. The locking assembly 234 can be a bolt structure for locking or a locking buckle structure. In this embodiment, a locking buckle structure is preferred to achieve quick adjustment of the position of the front wheel 233. At the same time, the locking buckle is a commonly used structure, and the detailed structure will not be described in detail in this application.

[0088] It should be noted that when the front wheel 233 changes direction actively, that is, by changing the swing direction of the front wheel 233 through external force, the direction of travel of the tractor is controlled. Preferably, the front wheel 233 is located in the first rotation position 2311 to improve the smoothness, stability and convenience of the steering process.

[0089] When the front wheel 233 changes direction passively, that is, when the front wheel 233 acts as a swivel wheel, the direction of travel of the front wheel 233 is not directly changed by external force. The change of direction is achieved by the swing of the tractor body 1 in combination with the friction between the front wheel 233 and the ground.

[0090] It should be noted that when the front wheel 233 is in the first rotation position 2311, if the operating assembly 22 is connected to the vehicle body 1, it is particularly difficult to control the steering of the front wheel 233 through the vehicle body 1, which affects the smoothness of operation. If the front wheel 233 is to be adjusted to the second rotation position 2312, a lever arm structure is formed between the rotation center of the rotating shaft 223 and the second rotation position 2312, which improves the smoothness of steering of the front wheel 233 and thus improves the operator's sense of the tractor.

[0091] Example 3

[0092] like Figures 1-3 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 3 and Embodiment 1 is as follows:

[0093] In this embodiment, the vehicle body 1, the control component 2, the traction connection component 3, and the drive component 4 are all detachably connected and can be quickly replaced according to different functions and customer requirements to meet different user needs.

[0094] Furthermore, the control component 2 is connected to the vehicle body 1 via fasteners, enabling quick assembly and disassembly, and allowing for the replacement of different types of control components 2 according to different user needs.

[0095] Preferably, the traction connection component 3 is quickly assembled and disassembled with the vehicle body 1 by plugging it in and using fasteners. Specifically, the traction connection component 3 is plugged into the vehicle body 1 and connected to the vehicle body 1 by several fasteners on both sides of the vehicle body 1. The traction connection component 3 can be selected according to different traction weights and traction types.

[0096] Preferably, the drive assembly 4 is detachably connected to the vehicle body 1, and a suitable traction connection assembly 3 can be selected according to different traction weights to meet the needs of different traction weights.

[0097] Example 4

[0098] like Figure 2 , Figure 3 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 4 and Embodiment 1 is as follows:

[0099] In this embodiment, the traction connection assembly 3 includes:

[0100] Connecting frame 31, the connecting frame 31 is connected to the vehicle body 1;

[0101] And a traction fixing member 32, which is used to detachably connect the traction fixing member 32 to the connecting frame 31 for connecting the object to be pulled;

[0102] The traction fixing component 32 is a traction column 321 installed on the top of the connecting frame 31 or a traction bolt 322 installed at the tail of the connecting frame 31.

[0103] It should be noted that customers can select different traction fixing parts 32 according to different traction needs to meet different working conditions and improve the equipment's versatility and adaptability to multiple working conditions.

[0104] The top towing column 321 is suitable for structures where the object to be towed needs to be quickly disassembled, while also ensuring stable operation and meeting the requirements for rapid and automated disassembly of the goods to be towed.

[0105] The 322 towing bolt at the rear is suitable for heavy loads and conditions prone to swaying, ensuring a stable connection between the cargo to be towed and the tractor.

[0106] The traction column 321 has a structure that is larger at the top and smaller at the bottom, which facilitates the limiting of the cargo to be towed during the towing process. Preferably, the top of the traction column 321 is spherical, which facilitates the quick assembly and disassembly of the cargo to be towed.

[0107] Furthermore, the towing column 321 is quickly connected via a locking pin, enabling rapid replacement of the towing column 321. Different towing columns 321 can be replaced with different ones to meet the requirements of different towing goods.

[0108] Preferably, the traction connection assembly 3 further includes counterweights 33 disposed on both sides of the connection frame 31 for changing the weight of the tractor.

[0109] It should be noted that by adding counterweights 33 of different weights, stable traction can be achieved for different traction weights, avoiding excessive traction weight that would prevent the tractor from driving. At the same time, by selecting appropriate counterweights 33 according to different traction weights, the weight of the tractor can be reduced to the greatest extent, saving energy and extending battery life.

[0110] Example 5

[0111] like Figure 1 , Figure 3 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 5 and Embodiment 1 is as follows:

[0112] In this embodiment, the control component 5 includes a controller, a battery that provides energy to the tractor, and a charger that charges the power source.

[0113] The control component 5 also includes a wireless control module, which is used to wirelessly control the tractor. The specific wireless connection method is existing technology, and this application will not elaborate on the specific connection method.

[0114] Preferably, the charger is either built-in or externally installed. Specifically, when the charger is built-in, it is installed inside the vehicle body 1 and connected to the power source via a plug to achieve fast charging.

[0115] Preferably, when the charger is externally mounted, a hidden charging interface is provided on the vehicle body 1, and the battery is charged by inserting an external charging plug into the charging interface.

[0116] The installation methods of the two chargers mentioned above can be adjusted according to user needs to meet the requirements of different working conditions.

[0117] Furthermore, the battery is provided in multiple groups, and the battery is connected in one or a combination of plug-in or fixed connection to meet the needs of different working conditions; specifically, the plug-in connection of the battery is suitable for the tractor to work for a long time, and the tractor can be operated continuously by replacing the battery.

[0118] When the tractor operates intermittently, a fixed battery can be installed. During the tractor's downtime, the battery can be charged as needed, reducing user operating costs.

[0119] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
