Example 1

A motor vehicle for tobacco hole-digging cultivation with transverse foot control steering is shown in figure 1 and comprises a roller device I100, a roller device II200 and a connecting device 300, wherein the roller devices are respectively arranged on two sides of the connecting device 300 and are linear, so that the size of a double-wheel monocycle is reduced to the maximum extent. Wherein,

the roller devices I, II100, 200 are respectively provided with rollers 101, 201 which can roll independently under the drive of the drive device 400; the driving device 400 is disposed at an outer side position of the roller devices I, II100, 200, the driving device 400 is usually a universal motor, and includes a storage battery with a certain size, in order to improve the structural strength of the whole roller device, the position of the driving device 400 including the storage battery is used as a foot part for placing an operator, the foot part 102 is used for the operator to step on, the connecting device 300 is respectively connected with the connecting parts 103 of the roller devices I, II100, 200, and the diameter of the connecting part 103 is gradually reduced from the diameter of the foot part 102 to be slightly larger than that of the connecting shaft 310 of the connecting device 300. The middle part of connecting portion 103 sets up a vertical wall 104 that extends along the radial direction of connecting axle 310 for support connecting portion 103 and the one end of fixed connecting axle 310, in addition, still is provided with a plurality of vertical, hollow support bars 105 in the one side of vertical wall 104 near connecting axle 310, is used for supporting connecting axle 310 in vertical direction further, reduces the connecting axle abnormal sound that causes because single vertical wall 104 connects unstably and the problem of the vibration of traveling. Further, the middle of the supporting bar 105 near the whole wheelbarrow is provided with at least one second supporting wall 106 for installing the fixed supporting device 331 and the bearing 332. The second support wall 106 extends along the radial direction of the connecting shaft 310, and forms an annular structure in the circumferential direction of the connecting shaft 310, so that the structural strength of the connecting portion 103 is further enhanced, and the stability of the whole vehicle is improved.

Two ends of the connecting device 300 are respectively connected with the roller device I100 and the roller device II200, and further, the connecting device 300 comprises a connecting shaft 310; the connection shaft 310 extends from one end of the connection device 300 to the other end, and the extending structure forms a unique offset structure of the connection shaft 310, by which the sensitivity and the lifespan of the rotation sensor of the connection shaft 310 are improved, and the offset structure is a state in which components or structures related to the connection shaft 310 are rearranged in the design of the structure to structurally form a structure having more functional components at one end of the connection shaft 310. The operator can change the roller device by controlling the acting force applied to the roller devices I, II100, 200 through foot force

I, II100, 200, thereby inducing attitude regulation of the wheelbarrow.

For the above-mentioned offset structure, in actual use, it is found that although there is an advantage that the manufacturing is more convenient in the existing connecting shaft 310 that is symmetrically arranged, because the inductor is through inducing the connecting shaft 310, there is often a problem that the left and right force is uneven when the operator exerts force through the leg, which often causes frequent start of the inductor for rotating the connecting shaft 310 on one side, and causes the aging due to overuse, and the rotation of the connecting shaft 310 cannot be well corresponded. In this way, in the present application, as a solution to the above problem, an offset structure is provided that extends from the roller device on one side of the wheelbarrow to the roller device on the other side, and in this solution, only one sensor is used and is provided only in the roller device on one side.

Further, in order to better improve the stability of the connection between the connection shaft 310 and the connection portion 103 and improve the operation experience of an operator, the following scheme may be adopted, in which the connection shaft 310 may be divided into two parts, including a shaft I320 and a shaft II330 which are coaxially disposed; the axis II330 is located in the direction in which one end of the axis I320 extends. The shafts I320 and II330 are hollow tubular structures having the same outer and inner diameters. The lower part of the end ports of the connecting shaft 310 are cut with a notch 107, as shown, the notch 107 is placed on the vertical support bar 105, and the rest of the end ports are abutted against the vertical wall 104, so as to form a firm connection and reduce the instability of the connecting shaft 310.

One end of the shaft I320 close to the roller device I100 is fixedly connected with the roller device I100, and one end of the shaft II330 close to the roller device II200 is fixedly connected with the roller device II 200; the other ends of the axes I320 and II330 are non-fixed ends and can be displaced relative to each other. Generally, the connection is achieved by a common connecting device. The non-fixed ends of the shafts I320 and II330 are movably connected, so that the shafts I320 and II330 rotate relatively, and the sensing device senses the direction rotation of the shafts by sensing the relative rotation of the shafts I320 and II 330.

Thus, shaft I320 can rotate relative to shaft II 330;

further, the shaft I320 is connected with the shaft II330 through a rotation limiting device 500 for limiting the relative rotation angle between the shaft I320 and the shaft II330, and the rotation limiting device 500 is also used for connecting the shaft I320 and the shaft II 330; the rotation limiting device 500 is generally a device for restoring the initial relative positions of the shaft I320 and the shaft II330 by using elastic force, and a spring or other similar elastic devices can achieve similar effects.

The rotation limiting device 500 is made of an elastic material, preferably rubber, and has two ends respectively connected to the shaft I320 and the shaft II330, and the elastic material is formed by a certain mold and then fixed to the two ends of the shaft I320 and the shaft II 330.

Further, the rotation restricting device 500 is required to have a structure in which a specific shape of the rotation restricting device 500 can be obtained by designing a corresponding mold.

The rotation limiting means 500 is formed as a twisted section 510 extending in the axial direction of the connecting shaft 310. The two ends of the twisted section 510 are connected to the shaft I320 and the shaft II330 respectively. The twisted section 510 serves to provide relative displacement of the shafts I320 and II330 and to elastically restore the position of the shafts I320 and II330 in dependence thereon. Alternatively, the twisted section is located between the shafts I320 and II330, and is generally a hollow tubular structure having the same inner diameter as the connecting shaft 310, but a different outer diameter. Further, a radially extending diaphragm, not shown, may be provided in the middle of the twisted section 510, and the thickness of the diaphragm is relatively thin, and the average thickness should be at least smaller than the thickness of the pipe wall of the connecting shaft 310, but the thickness should not be too small. In addition, the diaphragm may have a thickness gradually increasing from the inside to the outside, and the central portion may be thinner. The diaphragm is used to prevent the rotation of the shafts I320 and II330 from being affected by the sagging of the middle portion of the twisted section 510 due to gravity. Through determination, after the diaphragm is arranged, the service life of the twisting section 510 can be further prolonged, the anti-telescoping capability of the twisting section is improved, and deformation is prevented.

Further, the twisting segment 510 extends outwards in the radial direction of the connecting shaft 310, and both ends of the rotation limiting device 500 extend along the outer side surface of the shaft I or the shaft II to form an extension segment 520, i.e. the extension portion of the twisting segment 510 extends towards the direction of the shaft I320 or the shaft II330 and covers part of the outer side surface of the shaft I320 or the shaft II 330. The extension 520 serves to improve the connection between the rotation limiting device 500 and the shafts I320 and II330, and particularly to strengthen the connection of the edges of the twisted section 510, preventing the influence of frequent telescoping. In addition, the extension 520 may also serve well for stabilization.

Further, in order to improve the stability of the shaft I320, the rotation limiting device 500 further includes a cover section 530; the covering section 530 is located on the outer side surface of the shaft I, and preferably, the shaft I320 is generally short and should cover at least a part or most of the outer side surface of the shaft I320; the covering section 530 is extended from the extending section 520. Further, the cover section 530 should extend at least as far as the support bar 105 and be fixedly connected to the support bar 105. The outer diameter of the cover section 530 should be slightly larger than the outer diameter of the other portions of the rotation-restricting device 500, and at the same time, one end of the cover section 530 should abut against the support bar 105 to prevent direct contact between the shaft I320 and the support bar 105.

Preferably, the length of the axis I320 is less than the length of the axis II 330. Further, the length of the shaft I320 should be much smaller than the length of the connecting portion 103 of the roller device I100, at least less than 1/2 of the connecting portion 103, and preferably substantially equivalent to 1/3-1/4 of the connecting portion 103.

The restraining connection 300 is located on the side of the connection 300 near the axis I320.

The limiting connection device 300 is located in the roller device I100.

The diameter of the rotation limiting device 500 decreases in the direction from the axis I320 to the axis II 330.

The diameter of the covering section 530 of the rotation limiting means 500 is larger than the diameter of the extension section 520.

Further, after one end of the shaft II330 extends toward the shaft I320 to the fixed supporting device 331 located at the roller device II200, the end continues to extend through the bearing 332 located at the roller device I100 to the rotation limiting device 500, the fixed supporting device 331 is used for the fixed connection between the shaft II330 and the roller device II200, and the bearing 332 is used for the movable connection between the shaft II330 and the roller device I100. The fixed supporting device 331 is located in the roller device near the shaft II330, and in order to balance with the roller device on the other side, 2 fixed supporting devices 331 are usually provided, and the fixed supporting devices 331 are fixedly connected with the shaft II 330. A bearing 332 is provided in the roller device adjacent to the shaft I320, one side of the bearing 332 abutting against an extension of the restraining connection 300, with which extension 520 the lateral movement of the shaft II330 is prevented. Therefore, the shaft I320 is not provided with other supporting parts except the supporting bars 105, and the structure can effectively reduce the vibration problem caused by the rotation of the shaft I320 due to the short length of the shaft I320.
