The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0033] See also Figures 1 to 3 The utility model discloses a shock-absorbing unicycle, which includes a motor wheel 1, an upper body 2, a battery frame 4, a shock-absorbing mechanism 6 and two columns 3; the motor wheel 1 has a wheel axle 11, the two columns 3 are respectively connected to the two ends of the wheel axle 11, the upper body 2 is fixedly connected to the upper ends of the two columns 3, and the relative positions of the upper body 2 and the wheel axle 11 are fixed; the battery frame 4 is slidably arranged on the columns 3 up and down; the shock-absorbing mechanism 6 is movably connected between the upper body 2 and the battery frame 4.

[0034] The shock-absorbing unicycle provided in the present embodiment has an upper body 2 which remains at a constant distance relative to the wheel axle 11 in the vertical direction when traveling, and a battery frame 4 slides up and down relative to a column 3. Driven by the battery frame 4, a shock-absorbing mechanism 6 can move to provide shock absorption. In this way, the upper body 2 remains stationary relative to the motor wheel 1, and there is no need to reserve a lifting space for the upper body 2, thereby achieving the purpose of lowering the height of the upper body 2. In this way, the overall height of the shock-absorbing unicycle can be ensured to be low, so as to lower the center of gravity and thus improve riding stability.

[0035] Specifically, in this embodiment, the upper body 2 is used to mount circuit components.

[0036] like Figure 1 As shown, specifically, in this embodiment, the shock-absorbing unicycle also includes a foot pedal 9, which is connected to the lower end of the battery frame 4 and moves synchronously with the battery frame 4.

[0037] Specifically, in this embodiment, a third connecting hole extending laterally is provided at the lower end of the column 3, a fourth connecting hole is provided on the axle 11, and the shock-absorbing unicycle also includes a second fastener, which is inserted into the third connecting hole and the fourth connecting hole to fix the column 3 to the axle 11.

[0038] Specifically, in this embodiment, the upper body 2 is penetrated by a first connecting hole extending up and down, and the upper end of the column 3 is provided with a second connecting hole extending up and down. The shock-absorbing unicycle also includes a first fastener, which is inserted into the first connecting hole and the second connecting hole to fix the upper body 2 and the column 3. In this way, the connection is simple and convenient, and the production cost is low.

[0039] It should be noted that, in some other embodiments, the upper body 2 and the column 3 may be, but are not limited to, an integrally formed structure, thereby achieving the purpose of saving production costs and improving structural strength.

[0040] like Figure 2 and Figure 3As shown, specifically, in this embodiment, the shock absorbing mechanism 6 includes a shock absorber 67, a first connecting rod 65 and a second connecting rod 66, the shock absorber 67 has a first end 671 and a second end 672; the first connecting rod 65 is hinged to the upper body 2, and the hinge point between the first connecting rod 65 and the upper body 2 is the first hinge point 61; the second connecting rod 66 is hinged to the battery frame 4, and the hinge point between the second connecting rod 66 and the battery frame 4 is the second hinge point 62, specifically, the second hinge point 62 moves up and down following the up and down movement of the battery frame 4; the first connecting rod 65 and the second connecting rod 66 are connected to each other. They are hinged to each other, with the first end 671 hinged to the first connecting rod 65 and the second end 672 hinged to the second connecting rod 66; preferably, in this embodiment, the second hinge point 62 is located below the first hinge point 61, and when the second hinge point 62 moves downward relative to the first hinge point 61, the first end 671 and the second end 672 move toward each other, that is, the shock absorber 67 is compressed to provide a shock absorbing function, and when the second hinge point 62 moves upward relative to the first hinge point 61, the first end 671 and the second end 672 move away from each other, that is, the shock absorber 67 is stretched and rebounds.

[0041] In this way, on the one hand, the shock absorber 67 is not arranged on any component of the upper body 2 and the battery frame 4, so that the shock absorber 67 and the components for installing the shock absorber 67 can be transferred to the outside of the space area between the upper body 2 and the battery frame 4, which not only reduces the structural space occupied by the upper body 2 and the battery frame 4, making the overall structure of the wheelbarrow more concise and compact, but also further reduces the height of the upper body 2, thereby improving the stability of the wheelbarrow and the user's driving safety; on the other hand, when the wheelbarrow encounters bumps or impacts, the first connecting rod 65 and the second connecting rod 66 can convert the impact force into an axial compression force on the shock absorber 67, instead of generating a force in the radial direction of the shock absorber 67, thereby preventing the side wall of the shock absorber 67 from bending or breaking due to excessive load, thereby improving the service life of the shock absorber 67 and the reliability of the overall structure.

[0042] like Figure 3 As shown, specifically, in this embodiment, the hinge point between the first end 671 and the first connecting rod 65 is the fourth hinge point 64, and the fourth hinge point 64 is located above the first hinge point 61, so as to achieve the purpose of setting the first end 671 of the shock absorber 67 above the upper body 2, thereby further achieving the purpose of reducing the structural space occupied by the upper body 2 and the battery frame 4, and further reducing the height of the upper body 2.

More preferably, in this embodiment, the second connecting rod 66 extends toward the rear and upper direction of the travel direction of the wheelbarrow, so as to achieve the purpose of reducing the overall space occupied by the shock absorbing mechanism 6. Specifically, the travel direction of the wheelbarrow can refer to Figure 2 The e1 direction in .

[0044] It should be noted that, in some other embodiments, the second connecting rod 66 may also extend toward the rear and lower direction of the wheelbarrow's travel direction, or the second connecting rod 66 may also be parallel to the horizontal direction and extend toward the rear of the wheelbarrow's travel direction; it can be selected according to actual needs and is not a sole limitation here.

[0045] Specifically, in this embodiment, when the second hinge point 62 moves downward relative to the first hinge point 61, the third hinge point 63 and the fourth hinge point 64 move toward each other, and the first end 671 and the second end 672 move toward each other, that is, the shock absorber 67 is compressed to provide a shock absorbing function; when the second hinge point 62 moves upward relative to the first hinge point 61, the third hinge point 63 and the fourth hinge point 64 move away from each other, and the first end 671 and the second end 672 move away from each other, that is, the shock absorber 67 is stretched and rebounds.

More preferably, in this embodiment, the third hinge point 63 is located between the first hinge point 61 and the second hinge point 62 in the vertical direction, which can also reduce the active space required for the shock absorber 67 to be extended and retracted.

[0047] like Figure 3 As shown, specifically, in this embodiment, the first hinge point 61 is located on the rear side of the upper body 2 in the direction of travel of the wheelbarrow, the line connecting the second hinge point 62 and the middle hinge point 68 is the first line, and the line connecting the third hinge point 63 and the middle hinge point 68 is the second line. Preferably, the first line and the second line form a first angle, and the first angle is an obtuse angle facing downward. In this way, the horizontal spacing of the second end 672 of the shock absorber 67 relative to the upper body 2 can be larger, and the height of the second end 672 of the shock absorber 67 in the vertical direction can be appropriately reduced, so that the activity space occupied by the first end 671 of the shock absorber 67 on the upper body 2 can be reduced as much as possible.

[0049] like Figure 1 and Figure 5 As shown, preferably, in this embodiment, the second connecting rod 66 is provided with a hinge groove 663, and the first connecting rod 65 is inserted into the hinge groove 663 and hinged in the hinge groove 663. The setting of the hinge groove 663, on the one hand, can provide positioning and guidance for the hinge connection between the first connecting rod 65 and the second connecting rod 66, thereby improving the hinge efficiency and hinge stability between the first connecting rod 65 and the second connecting rod 66, and on the other hand, can also achieve the purpose of reducing the overall occupied space of the shock absorbing mechanism 6. Specifically, the hinge groove 663 is provided at the intersection between the first connecting section 661 and the second connecting section 662.

It can be selected according to actual needs and is not limited here.

[0052] See also Figure 1 , Figure 4 and Figure 5Specifically, in this embodiment, the upper body 2 is provided with a controller (not shown). Preferably, the shock-absorbing unicycle also includes a handle box 5, which includes an outer box body 51 and an electrical connection plate 52. The outer box body 51 is connected to the battery frame 4. The outer box body 51 is located in front of the upper body 2 in the driving direction. The outer box body 51 is used for the user to lift the unicycle. The electrical connection plate 52 is provided on the outer box body 51. The electrical connection plate 52 is electrically connected to the above-mentioned controller and the battery 8 through wires (not shown). In this way, the outer box body 51 is connected to the battery frame 4. The electrical connection plate 52 moves synchronously with the battery frame 4, that is, the electrical connection plate 52 moves synchronously with the battery frame 4. The relative positions of the electrical connection plate 52 and the battery frame 4 can remain unchanged when the shock-absorbing unicycle is traveling, that is, the relative positions of the electrical connection plate 52 and the battery 8 can remain unchanged.

[0053] like Figure 1 and Figure 3 As shown, preferably, in this embodiment, in order to further enhance the user experience, the outer box body 51 is designed to be inclined toward the upper rear side in the direction of travel. This inclined design not only facilitates the user to lift and apply force, but also helps to connect the wires between the electrical connection board 52 and the battery 8 and the controller, making the wiring simpler and smoother.

[0054] like Figure 4 As shown, preferably, in this embodiment, the outer box body 51 has a mounting side wall 511 facing the motor wheel 1, and the mounting side wall 511 is also inclined toward the upper rear of the driving direction.

Preferably, a second wire groove 211 is provided on the connecting side wall 21 for routing and installing the second wire.

[0059] In summary, the shock-absorbing unicycle disclosed in the utility model can at least bring the following beneficial technical effects:

[0060] 1) The upper body 2 remains stationary relative to the motor wheel 1, so there is no need to reserve lifting space for the upper body 2, thereby achieving the purpose of lowering the height of the upper body 2 and ensuring that the overall height of the shock-absorbing unicycle is low, thereby lowering the center of gravity and improving riding stability;

[0061] 2) The shock absorber 67 is not arranged on any of the upper body 2 and the battery frame 4, which not only reduces the structural space occupied by the upper body 2 and the battery frame 4, making the overall structure of the wheelbarrow more concise and compact, but also further reduces the height of the upper body 2, thereby improving the stability of the wheelbarrow and the driving safety of the user;

[0062] 3) The first connecting rod 65 and the second connecting rod 66 can convert the impact force into an axial compression force on the shock absorber 67, rather than generating a force in the radial direction of the shock absorber 67, thereby preventing the side wall of the shock absorber 67 from bending or breaking due to excessive load, thereby improving the service life of the shock absorber 67 and the reliability of the overall structure;

[0063] 4) The second connecting rod 66 extends toward the upper rear direction in the direction of travel of the wheelbarrow, so as to achieve the purpose of reducing the overall space occupied by the shock absorbing mechanism 6; and the first connecting line and the second connecting line form a first angle, which is an obtuse angle pointing downward, so that the horizontal distance between the second end 672 of the shock absorber 67 and the upper body 2 can be larger, and the height of the second end 672 of the shock absorber 67 in the vertical direction can be appropriately reduced, so that the active space occupied by the first end 671 of the shock absorber 67 on the upper body 2 can be reduced as much as possible.
