Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0026] like Figure 1 As shown, this embodiment discloses a three-wheeled lifting vehicle, which includes a vehicle assembly 1, a lifting component 2 and a cargo platform 3, wherein the lifting component 2 is arranged on the vehicle assembly 1, and is used to drive the cargo platform 3 to adjust its height up and down to facilitate the docking of cargo.

[0027] like Figure 2 As shown, the vehicle assembly 1 includes a vehicle body 11 and an operating component 12; the lower end of the vehicle body 11 is respectively provided with two active wheels 13 and a passive wheel 14 for walking, and the active wheels 13 can be driven to rotate, thereby driving the vehicle body 11 forward or backward, and the operating component 12 is set on the vehicle body 11, and is used to control the direction of the passive wheels 14 and control the walking of the active wheels 13.

[0028] like Figure 2 As shown, two driving wheels 13 are arranged side by side at the rear end of the vehicle body 11, and a passive wheel 14 is arranged at the front end of the vehicle body 11, so that the two driving wheels 13 and one passive wheel 14 form a triangular distribution.

[0029] like Figure 3 As shown, the operating assembly 12 is disposed at the front end of the vehicle body 11 and can be used to control the movement and steering of the vehicle body 11. The operating assembly 12 includes a mounting member 121, a steering bracket 122, a wheel frame 123, a steering rod 124, an elastic member 125, and an accelerator pedal 126, as follows:

[0030] like Figure 3 and Figure 4 As shown, the mounting member 121 is arranged on the vehicle body 11 for mounting the steering bracket 122; the steering bracket 122 passes through the mounting member 121 along the height direction, and there is a certain gap between the outer periphery of the steering bracket 122 and the mounting member 121, so that the steering bracket 122 can rotate with the mounting member 121 in the horizontal circumferential direction.

[0031] like Figure 4 As shown, the mounting member 121 includes a connecting plate 1211 and a steering sleeve 1212. Figure 5 As shown, the front end of the vehicle body 11 is provided with an installation position, and the installation position is provided with upper and lower through holes 11a. The connecting plate 1211 is fixedly provided on the installation position at the front end of the vehicle body 11. The steering sleeve 1212 is passed through the connecting plate 1211, and the steering sleeve 1212 and the connecting plate 1211 are fixedly connected. The steering bracket 122 passes through the steering sleeve 1212 and the through hole 11a on the installation position along the height direction, and the steering bracket 122 can rotate circumferentially with the steering sleeve 1212.

[0032] like Figure 3 As shown, the lower end of the steering bracket 122 is fixedly connected to the wheel frame 123, and the passive wheel 14 is rotatably provided on the wheel frame 123. When the steering bracket 122 rotates circumferentially, it can drive the passive wheel 14 to rotate, thereby changing the movement direction of the vehicle body 11. One end of the steering rod 124 is hinged to the upper end of the steering bracket 122, so that the steering rod 124 can swing up and down relative to the steering bracket 122. The two ends of the elastic member 125 (such as a spring) are respectively connected to the upper end of the steering bracket 122 and the steering rod 124. The elastic force of the elastic member 125 makes the steering rod 124 tend to tilt upward; the accelerator pedal 126 is arranged on the steering bracket 122, and the accelerator pedal 126 and the steering rod 124 in the height direction at least partially overlap (that is, the accelerator pedal 126 is located below the steering rod 124). When the tension of the elastic member 125 is overcome and the steering rod 124 is pressed downward, the steering rod 124 can press the accelerator pedal 126 downward, and the accelerator pedal 126 thereby controls the driving wheel 13 to move. When the steering rod 124 is released, the steering rod 124 automatically returns to its original position under the action of the elastic member 125, and the steering rod 124 is disengaged from the accelerator pedal 126, and the accelerator pedal 126 returns to its non-working state.

[0033] like Figure 6 As shown, in this embodiment, a U-shaped mounting portion 1221 is provided at the upper end of the steering bracket 122, with the opening of the U-shaped mounting portion 1221 facing upward; an accelerator pedal 126 is disposed within the U-shaped mounting portion 1221, and a steering rod 124 is hinged to the opening of the U-shaped mounting portion 1221 via a pin. When in the initial state (i.e., when the steering rod 124 is not subjected to external force), the elastic member 125 pulls the steering rod 124 upward, and the steering rod 124 does not apply downward pressure to the accelerator pedal 126. At this time, the accelerator pedal 126 is inoperative, and the driving wheel 13 does not move. If a person manually presses down on the steering rod 124, the steering rod 124 applies downward pressure to the accelerator pedal 126, and the accelerator pedal 126 is thus inoperative, causing the driving wheel 13 to move.

[0034] like Figure 6 As shown, in this embodiment, a horizontal plate 127 is fixedly mounted on the open end surface of the U-shaped mounting portion 1221. A threaded adjustment member 128 (e.g., a bolt) is threadedly connected to the middle portion of the horizontal plate 127. The threaded adjustment member 128 can be screwed in or out upward. The lower end of the threaded adjustment member 128 can abut against the upper surface of the steering rod 124, thereby limiting the upward angle of the steering rod 124. One end of the elastic member 125 is connected to the horizontal plate 127, and the other end of the elastic member 125 is connected to the steering rod 124.

[0035] like Figure 4 As shown, in some preferred embodiments, the operating component 12 also includes a protective cover 129, which is arranged at the upper end of the steering bracket 122 to provide protection for other components, wherein the U-shaped mounting portion 1221, the accelerator pedal 126, the cross plate 127, the elastic member 125 and at least part of the steering rod 124 are all arranged in the protective cover 129, and in order not to hinder the up and down swinging of the steering rod 124, the protective cover 129 is also provided with a strip opening along the height direction, and the strip opening can avoid the up and down swinging of the steering rod 124.

[0036] like Figure 4 As shown, in some preferred embodiments, the steering rod 124 is a circular rod with a certain length. One end of the steering rod 124 is hinged to the steering bracket 122, and the other end of the steering rod 124 away from the steering bracket 122 is fixedly provided with a U-shaped handle 1241. The U-shaped handle 1241 facilitates the staff to press down and rotate the steering rod 124.

[0037] The vehicle body 11 in this embodiment can refer to existing technologies. For example, the vehicle body 11 is provided with a power unit, a transmission unit, a control unit, and other structures. The power unit is connected to the two active wheels 13 on the vehicle body 11 through the transmission unit. The power of the power unit can drive the active wheels 13 to move on the ground. The control unit is directly or indirectly connected to the power unit. The control unit is connected to the accelerator pedal 126. When the accelerator pedal 126 is pressed, the accelerator pedal 126 generates an operating signal. The control unit controls the operation of the power unit based on the operating signal. It should be noted that the details of how the accelerator pedal 126 controls the active wheels 13 to move on the ground are referred to in the existing technology and will not be repeated here.

[0038] like Figure 7 As shown, the cargo platform 3 is arranged on the lifting assembly 2, and the lifting assembly 2 can drive the cargo platform 3 to move up and down. The lifting assembly 2 includes a fork frame 21, a first connecting shaft 22, an intermediate shaft 23, a second connecting shaft 24, a lifting cylinder 25 and a transition platform 26;

[0039] like Figure 7 As shown, there are two forks 21, which are arranged on the back side of the vehicle body 11 along the width direction of the vehicle body 11. The fork 21 includes a first lever arm 211 and a second lever arm 212. The middle positions of the first lever arm 211 and the second lever arm 212 are hinged to each other to form an X-shaped structure.

[0040] like Figure 7 As shown, the first connecting shaft 22 passes through the lower ends of the two first lever arms 211 along the width direction, and the end of the first connecting shaft 22 is hinged to the back side of the vehicle body 11; the axial ends of the intermediate shaft 23 are respectively fixedly connected to the middle positions of the two second lever arms 212 (specifically, an inner plate is fixedly provided on the inner side of the second lever arm 212, and the intermediate shaft 23 is fixedly connected to the inner plate), the second connecting shaft 24 passes through the lower ends of the two second lever arms 212 along the width direction, and a slider 241 is provided at the end of the second connecting shaft 24, and a slide groove (not shown) is provided on the vehicle body 11, which is opened in the horizontal direction (i.e., the length direction of the vehicle body 11), and the slider 241 The slide is set in the slide groove, and the slide groove limits the slider 241 to slide only in the length direction of the vehicle body 11; one end of the lifting cylinder 25 is hinged to the first connecting shaft 22, and the other end of the lifting cylinder 25 is hinged to the intermediate shaft 23; the transition platform 26 is set at the upper end of the first force arm 211 and the second force arm 212. When the lifting cylinder 25 is extended, the lifting cylinder 25 pushes the fork frame 21 to change the angle, and the transition platform 26 is immediately lifted upward. Conversely, when the lifting cylinder 25 is retracted, the transition platform 26 is lowered; wherein, the cargo platform 3 is set on the transition platform 26, and the cargo platform 3 can adjust the height up and down following the transition platform 26.

[0041] like Figure 8 and Figure 9 As shown, in some embodiments, a plurality of weighing components 31 (such as weighing sensors, etc.) are provided on the lower side of the cargo platform 3. The weighing components 31 are located between the cargo platform 3 and the transition platform 26 and can be used to weigh the weight of the cargo on the cargo platform 3.

Those skilled in the art will clearly understand that for the convenience and brevity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the scope of protection of the present application.
