[0047] For the purpose of making the purposes, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, but not to limit the present application. The present application can be implemented without some of the specific details by those skilled in the art. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0048] It should be noted that, in this paper, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or equipment including the elements.

[0049] For a better understanding of the present application, in one aspect, the following will be described in detail Figures 1 to 6 According to the embodiments of the present application, a detailed description is provided.

[0050] Figure 1 Figure 1 A structure schematic diagram of a steering wheel in a first state is provided for some embodiments of the present application. Figure 2 A structure schematic diagram of a steering wheel in a second state is provided for some embodiments of the present application. Figure 3 An explosion schematic diagram of a steering wheel is provided for some embodiments of the present application.

[0051] As Figures 1 to 3As shown, the embodiment of the present application provides a steering wheel 10, which has a first state S1 and a second state S2. The steering wheel 10 comprises a driving adjusting device 100 and a driving device 200. The driving adjusting device 100 comprises a fixing assembly 110, a pressure adjusting assembly 120 and a mounting piece 130. The fixing assembly 110 is movably connected with the mounting piece 130. The pressure adjusting assembly 120 is arranged on the fixing assembly 110 and located between the fixing assembly 110 and the mounting piece 130. The fixing assembly 110 is fixed to a vehicle body. The driving device 200 is arranged on a side of the mounting piece 130 away from the fixing assembly 110, and is used to drive the steering wheel 10 to move. In the process of changing from the first state S1 to the second state S2, one end of the pressure adjusting assembly 120 away from the fixing assembly 110 abuts against the mounting piece 130, so that the mounting piece 130 presses the driving device 200 along a first direction X. The first direction X is a side-by-side direction of the mounting piece 130 and the driving device 200.

[0052] The steering wheel 10 comprises the driving adjusting device 100, the driving device 200, a driving motor 510, a gear set and a reduction box 240, and can realize the forward movement, backward movement, braking and steering of the steering wheel 10. In some optional examples, the steering wheel 10 is applied to a transportation device 20. The movement of the steering wheel 10 drives the transportation device 20 to move, so as to realize the transportation of the transportation device 20 to articles.

[0053] In some examples of the embodiment, the first state S1 is an empty state of the steering wheel 10, and the second state S2 is a loaded state of the steering wheel 10. In the first state S1, the transportation device 20 carrying the steering wheel 10 does not place articles to be transported. In the second state S2, the transportation device 20 carrying the steering wheel 10 places articles to be transported. In the second state S2, the transportation device 20 carrying the steering wheel 10 can place articles with different weights.

[0054] The process of changing from the first state S1 to the second state S2, in other words, the process of placing articles to be transported on the transportation device 20 carrying the steering wheel 10. In this process, the articles to be transported are placed on the transportation device 20. The transportation device 20 feeds back the weight of the articles to be transported to the steering wheel 10. The driving adjusting device 100 of the steering wheel 10 applies pressure to the mounting piece 130 according to the weight of the articles to be transported, so as to provide the driving device 200 with corresponding driving force by the mounting piece 130.

[0055] The fixed assembly 110 in the driving adjustment device 100 can be fixed on the vehicle body of the transport device 20 by means of bolts, welding, riveting, etc., for fixing the driving adjustment device 100 and the tiller 10 on the vehicle body. In some examples of the embodiment, the number of the fixed assemblies 110 can include multiple, so as to improve the stability of the tiller 10 on the transport device 20. The shape of the fixed assembly 110 includes a long strip, a plate, etc., so as to be more flexible to be installed on the transport device 20.

[0056] One end of the pressure adjustment assembly 120 is fixed on the fixed assembly 110, so that the pressure adjustment assembly 120 is offset during work, resulting in poor or even failure of the pressure adjustment effect. The other end of the pressure adjustment assembly 120 can be relatively moved relative to the one end fixed on the fixed assembly 110, and the movable end is moved along the direction from the fixed assembly 110 to the mounting 130, and the mounting 130 transmits the pressure to the driving device 200, the pressure on the driving device 200 is increased, and the friction between the driving device 200 and the driving surface is also increased, thereby increasing the driving force of the driving device 200.

[0057] In some optional embodiments, the pressure adjustment assembly 120 includes a hydraulic device, a lead screw device, etc. The tiller 10 will output instructions to the pressure adjustment assembly 120 according to the load condition by the encoder, and the pressure adjustment assembly 120 applies pressure to the mounting 130 through the instructions, thereby increasing the driving force of the tiller 10.

[0058] Optionally, in the first state S1, the movable end of the pressure adjustment assembly 120 can not be in contact with the mounting 130, thereby simplifying the assembly difficulty of the pressure adjustment assembly 120.

[0059] The mounting 130 is used to carry the driving device 200, and the mounting 130 is movable relative to the fixed assembly 110. In some examples, the mounting 130 can be installed on the vehicle body, and the connection between the vehicle body and the mounting 130 can be gap-fitted, and the mounting 130 is limited by the structure on the vehicle body, so that the mounting 130 has a fixed moving distance. In some other examples, a connecting assembly is arranged between the fixed assembly 110 and the mounting 130, the fixed assembly 110 is fixedly connected with the vehicle body through the connecting assembly, the mounting 130 is gap-fitted with the connecting assembly, and a limiting portion is arranged on the connecting assembly, so that the mounting 130 has a fixed moving distance on the connecting assembly.

[0060] It can be understood that, in the process of transforming from the first state S1 to the second state S2, the pressure adjusting assembly 120 moves the mounting member 130 away from the fixed assembly 110, in the process of transforming from the second state S2 to the first state S1, the pressure applied by the pressure adjusting assembly 120 to the mounting member 130 gradually decreases until disappears, in this process, the driving force of the driving device 200 can exceed the load force of the steering wheel 10, the mounting member 130 can move towards the fixed assembly 110 to reduce the driving force of the driving device 200, until the first state S1 is restored, the driving device 200 does not need the mounting member 130 to provide additional driving force, and the mounting member 130 can move to a position where it is not subjected to the pressure applied by the pressure adjusting assembly 120.

[0061] The driving device 200 is fixedly connected with the mounting member 130, and the driving device 200 is used to drive the steering wheel 10 to move. For example, the driving device 200 includes a driving wheel 220, a driven wheel, a speed reducer 240, a motor and other components to realize the forward movement, backward movement and braking of the steering wheel 10. In some examples, a damping device is further arranged between the driving device 200 and the mounting member 130, so as to reduce the impact force of the driving device 200 on the mounting member 130 caused by the bumping of the driving surface.

[0062] According to the steering wheel 10 and the driving adjusting device 100 and the driving device 200 of the transportation device 20 provided in the present application, when the steering wheel 10 is transformed from the first state S1 to the second state S2, the driving adjusting device 100 applies pressure to the mounting member 130 through the pressure adjusting assembly 120, and the mounting member 130 transmits the pressure to the driving device 200, so that the driving device 200 obtains greater driving force, thereby avoiding the phenomenon of slippage or driving failure of the driving device 200 when the first state S1 is transformed to the second state S2 or in the second state S2.

[0063] Figure 4 A structural schematic diagram of a driving adjusting device 100 provided in some embodiments of the present application is shown. Figure 5 Another structural schematic diagram of a driving adjusting device 100 provided in some embodiments of the present application is shown.

[0064] As shown in Figure 3 and Figure 4 In some optional embodiments of the present application, the pressure adjusting assembly 120 includes a driving member 121 and an extension member 122, the driving member 121 is fixedly connected with the fixed assembly 110, and the extension member 122 is arranged at one end of the driving member 121 away from the fixed assembly 110.

[0065] The driving member 121 powers the extension member 122 to move towards the mounting member 130. In some examples of the embodiment, the driving member 121 is a hydraulic cylinder, which is in communication with a hydraulic pump on the vehicle body through a hydraulic pipeline. The hydraulic pump can provide hydraulic pressure to the hydraulic cylinder, which can press the extension member 122 to move. In other examples, the driving member 121 is an electric motor, and the extension member 122 is a screw rod assembly.

[0066] In the embodiment, the driving member 121 is fixedly connected with the fixed assembly 110 by bolts, welding, riveting or the like, so as to avoid the relative position deviation between the driving member 121 and the fixed assembly 110 during work, which can cause the insufficient pressure provided by the driving member 121. The extension member 122 moves between the fixed assembly 110 and the mounting member 130 to apply pressure to the mounting member 130, and then to provide driving force for the tiller 10.

[0067] As shown in Figure 4 , in some optional embodiments of the application, the pressure adjusting assembly 120 further comprises a buffer member 123, which is arranged at one end of the extension member 122 away from the driving member 121.

[0068] In some examples, the buffer member 123 is arranged between the extension member 122 and the mounting member 130, and one end of the buffer member 123 is fixedly connected with the extension member 122, so as to reduce the collision between the extension member 122 and the mounting member 130 when the extension member 122 contacts the mounting member 130, and improve the service life of the extension member 122. In other examples, the buffer member 123 is also arranged on the surface of the mounting member 130 facing the extension member 122, to further reduce the collision between the extension member 122 and the mounting member 130. Optionally, the buffer member 123 comprises a spring and an elastic base 123a. One end of the spring is fixed to one end of the extension member 122, and the other end of the spring is fixedly connected with the elastic base 123a.

[0069] As shown in Figure 4 and Figure 5 , in some optional embodiments of the application, the fixed assembly 110 comprises a first fixed member 111 and a second fixed member 112, which are arranged at intervals along the first direction X. The first fixed member 111 and the second fixed member 112 are respectively fixed on the vehicle body, so as to improve the stability of the tiller 10.

[0070] As shown in Figure 4 and Figure 5 , in some optional embodiments of the application, the mounting member 130 is located between the first fixed member 111 and the second fixed member 112, and the mounting member 130 has a preset movable stroke along the first direction X, which is 5mm-100mm.

[0071] The greater the distance that the mounting member 130 can move in the first direction X, the greater the volume required for the rudder 10, which is not conducive to miniaturization of the rudder 10. The smaller the distance that the mounting member 130 can move in the first direction X, the smaller the driving force that the mounting member 130 can provide for the driving device 200. If the distance that the mounting member 130 can move in the first direction X is too small, the mounting member 130 cannot provide sufficient driving force for the driving device 200. Therefore, the present embodiment limits the preset distance that the mounting member 130 can move in the first direction X to 5 mm to 100 mm, which is as small as possible while ensuring that the mounting member 130 can provide sufficient driving force for the driving device 200.

[0072] As shown in Figure 4 and Figure 5 , in some optional embodiments of the present application, the rudder 10 further comprises a guide assembly 300, which is arranged between the fixing assembly 110 and the mounting member 130 and is fixedly connected to the fixing assembly 110, and the mounting member 130 is movably connected to the guide assembly 300.

[0073] The mounting member 130 moves on the guide assembly 300 in the extension direction X of the guide assembly 300. In some optional examples of the present embodiment, the shape of the guide assembly 300 includes a rod shape or a plate shape. The mounting member 130 is provided with a mounting hole that cooperates with the guide assembly 300. It can be understood that the mounting hole on the mounting member 130 is in clearance fit with the guide assembly 300, so that the mounting member 130 can move on the guide assembly 300.

[0074] Please continue to refer to Figure 4 and Figure 5 , in some optional embodiments of the present application, the guide assembly 300 comprises a first guide rod 310 and a second guide rod 320, the first guide rod 310 and the second guide rod 320 are arranged in a spaced manner in a second direction Y, the first guide rod 310 and the second guide rod 320 are both arranged in connection with the fixing assembly 110, and the second direction Y is arranged in intersection with the first direction X.

The first guide rod 310 and the second guide rod 320 can provide more movable distance for the mounting member 130, and can provide more driving force for the driving device 200.

[0078] Please continue to refer to Figure 4 and Figure 5 In some optional embodiments of the present application, the mounting member 130 is movably connected with at least one of the first guide rod 310 and the second guide rod 320.

[0079] In some optional embodiments, the mounting member 130 comprises a mounting hole, and the mounting member 130 is sleeved on the first guide rod 310 and the second guide rod 320 through the mounting hole.

[0086] Please continue to refer to Figure 4 and Figure 5 In some optional embodiments of the present application, the rudder 10 further comprises a damping member 400, the damping member 400 is located between the fixed assembly 110 and the mounting member 130, and the damping member 400 is movably arranged relative to the fixed assembly 110 along the first direction X.

[0087] It should be noted that Figure 5 part of the damping member 400 is not shown.

[0088] Optionally, the damping member 400 includes a damping spring, a rubber shock absorber, etc.

[0089] In the present embodiment, the damping member 400 is used to absorb the extrusion force of the drive device 200 on the vehicle body when the rudder 10 travels on a bumpy road.

[0090] Please continue to refer to Figure 4 and Figure 5In some optional embodiments of the present application, the damping member 400 is arranged on the guide assembly 300, and the damping member 400 comprises a movable end along the length direction of the guide assembly 300, and the movable end of the damping member 400 is arranged close to the mounting member 130.

[0091] In some embodiments, the damping member 400 is sleeved on the guide assembly 300, and the end of the damping member 400 close to the fixed assembly 110 is fixedly connected with the guide assembly 300, so as to avoid that the damping member 400 generates an acting force on the fixed assembly 110 during the working process.

It can be understood that when the mounting member 130 moves on the guide assembly 300, the mounting member 130 is in contact with the damping member 400, and the damping member 400 can provide damping effect for the mounting member 130, so as to reduce the acting force of the mounting member 130 on the guide assembly 300 and the fixed assembly 110 during the moving process. In some other embodiments, both ends of the damping member 400 are movable along the length direction of the guide assembly 300.

[0096] Optionally, the driving motor 510 comprises a servo motor, a steering direct current motor.

[0097] In the present embodiment, through the cooperation of the first gear 520 and the driving device 200, the steering wheel 10 can be provided with a steering angle, and the driving motor 510 can provide steering force for the steering device 500.

[0098] Please continue to refer to Figure 6In some optional embodiments of the present application, the driving device 200 comprises a rotating support 210 and a driving wheel 220, the driving wheel 220 is arranged on the side of the rotating support 210 away from the mounting member 130, and the side of the rotating support 210 away from the driving wheel 220 is fixedly connected with the mounting member 130. The rotating support 210 is rotationally connected with the first gear 520.

[0099] The circumferential side of the rotating support 210 comprises a gear structure meshing with the first gear 520, and the meshing rotation of the first gear 520 with the rotating support 210 can drive the driving wheel 220 to realize the steering action. It can be understood that the rotating support 210 and the driving wheel 220 are fixedly arranged, and the rotation angle of the rotating support 210 is positively correlated with the steering angle of the driving wheel 220.

[0100] Optionally, the driving device 200 further comprises a second driving motor 510230 and a reduction box 240, so as to cooperate with the use of the first gear 520 and the second gear, thereby bringing the driving wheel 220 to a precise steering angle.

[0103] The mounting member 130 is provided with a mounting hole of the sensing member 610, so as to fix the sensing member 610 on the mounting member 130. It can be understood that the mounting hole can be a through hole or a blind hole.

[0104] The sensing member 610 can be provided with an indicator lamp for indicating whether the driving device 200 returns to the reset state after steering, and the sensing member 610 is arranged on the side of the mounting member 130 away from the driving device 200, which can be understood as the side that can be more convenient for a user to observe the indicator lamp. In some examples, the indicator lamp on the sensing member 610 is turned on, and the driving device 200 is in a steering state or is recovering to a reset state after steering. The indicator lamp on the sensing member 610 is turned off, and the driving device 200 is in a reset state.

[0105] The thickening member 620 is arranged between the second gear and the driving device 200. It can be understood that there is a gap between the second gear and the driving wheel 220, and the thickening member 620 does not fill the gap. The thickening member 620 is fixedly connected with the second gear, and can rotate with the second gear.

[0106] In some examples, the sensing member 610 can sense the presence of the thickening member 620 along the thickness direction of the mounting member 130, and determine whether the driving device 200 is restored to the reset state by sensing whether the thickening member 620 is within the sensing range. In other examples, the sensing member 610 can sense the gap distance between the second gear and the driving wheel 220 along the thickness direction of the mounting member 130, and determine whether the driving device 200 is restored to the reset state by sensing the size of the gap distance.

[0107] It should be noted that the reset state refers to the normal state of each component in the steering wheel 10 when the steering wheel 10 is in the first state S1.

[0108] Please continue to refer to Figure 6 In some optional embodiments of the present application, the thickening member 620 comprises a first sensing area, and the first sensing area is arranged at a variable position of the thickening member 620. In the first state S1, the projection of the sensing member 610 along the thickness direction of the mounting member 130 overlaps the first sensing area.

[0111] Optionally, the projection of the thickening member 620 along the thickness direction of the mounting member 130 has a shape similar to that of the rotary support 210, and covers a part of the rotary support 210.

[0112] Optionally, the thickness of the thickening member 620 is 2mm-10mm.

[0113] In the present embodiment, the projection of the sensing member 610 and the first sensing area along the thickness direction of the mounting member 130 is overlapped, that is, the sensing member 610 and the first sensing area are overlapped along the thickness direction of the mounting member 130. In the first state S1, the sensing member 610 and the first sensing area are overlapped along the thickness direction of the mounting member 130, which can simplify the assembly process and avoid the problem that the sensing member 610 cannot accurately sense whether the driving device 200 is reset due to assembly and manufacturing errors.

[0114] Please continue to refer to Figure 6In some optional embodiments of the present application, the projection of the thickening member 620 in the thickness direction is semi-annular, and the first sensing area is arranged at one end of the thickening member 620.

[0115] The semi-annular thickening member 620 is convenient to install on the rotary support 210, and as the rotary support 210 rotates, the thickening member 620 can rotate by the same angle, so that the sensing member 610 can more accurately sense the rotation angle of the thickening member 620, thereby knowing the rotation angle of the driving wheel 220.
