[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Example 1

[0038] Please also read Figures 1 to 6 , the balancing vehicle provided by the first embodiment of the present invention is now described. The first embodiment of the present invention provides a balancing vehicle, comprising a body 10, and two wheels 20 rotatably mounted on both sides of the body 10. The balancing vehicle also includes: a first pedal 30, a second pedal 40, an incomplete transmission wheel assembly 50, and a reset mechanism 60. The first pedal 30 and the second pedal 40 are rotatably mounted on both sides of the body 10, and are used to swing downward to provide the driving force required for the rotation of each wheel 20. The incomplete transmission wheel assembly 50 is connected to the first pedal 30 and the second pedal 40, respectively, and is used to convert the driving force generated by the downward swing of the first pedal 30 and the second pedal 40 into a rotational motion and transmit it to each of the wheels 20 to drive each of the wheels 20 to rotate. Through the arrangement of the incomplete transmission wheel assembly 50, the up and down reciprocating motion of the first pedal 30 and the second pedal 40 can be converted into a forward rotation or reverse rotation of the wheel 20, thereby realizing the forward or backward movement of the wheel 20, and is conducive to maintaining balance. The forward rotation of the wheel 20 refers to a rotation direction that drives the wheel 20 forward, and the reverse rotation of the wheel 20 refers to a rotation direction opposite to the forward rotation.

[0039] The reset mechanism 60 is connected to the first pedal 30 and the second pedal 40 respectively, and is used to realize the reverse swing of the first pedal 30 and the second pedal 40, so that when the first pedal 30 is at the lowest point of the stroke, the second pedal 40 is at the highest point of the stroke, and when the first pedal 30 is at the highest point of the stroke, the second pedal 40 is at the lowest point of the stroke. By alternately pedaling, the balancing vehicle continues to move forward or backward, which is not only conducive to maintaining balance, but also effectively solves the problem of complex structure and high cost caused by the use of electric balancing vehicles in the prior art.

[0040] Compared with the prior art, the balance vehicle provided by the present invention is a balance vehicle provided by the present invention. By providing a first pedal 30, a second pedal 40, an incomplete transmission wheel assembly 50 and a reset mechanism 60, the up and down reciprocating motion of the first pedal 30 and the second pedal 40 is converted into a forward rotation or a reverse rotation of the wheel 20 by utilizing the provision of the incomplete transmission wheel assembly 50. By alternately pedaling, the balance vehicle continues to move forward or backward, which is not only conducive to maintaining balance, but also effectively solves the problem of complex structure and high cost caused by the use of electric balance vehicles in the prior art. The structure is very simple, the transmission has no dead point, pedaling is time-saving and labor-saving, and the speed and comfort of the balance vehicle are effectively improved. In addition, by alternately pedaling the first pedal 30 and the second pedal 40, the swing amplitude of the first pedal 30 and the second pedal 40 can be appropriately reduced, so that both feet can land and support earlier in case of emergencies, and provide safe upright driving conditions.

[0041] For further information, please also refer to Figures 2 to 5As a specific implementation of the balancing vehicle provided by the first embodiment of the present invention, the incomplete transmission wheel assembly 50 includes a first transmission wheel 511, a second transmission wheel 512 and a first incomplete transmission wheel 513. The first transmission wheel 511 is connected to the first pedal 30, and the second transmission wheel 512 is connected to the second pedal 40, so that the first transmission wheel 511 or the second transmission wheel 512 can be driven to rotate by stepping on the first pedal 30 or the second pedal 40. The first incomplete transmission wheel 513 is rotatably mounted on the vehicle body 10, and the first incomplete transmission wheel 513 is meshed with the first transmission wheel 511 or the second transmission wheel 512. When the first incomplete transmission wheel 513 is meshed with the first transmission wheel 511, the first transmission wheel 511 can drive the wheel 20 to rotate forward or reversely, and the first incomplete transmission wheel 513 and the second transmission wheel 512 are in a state of no transmission matching, and the second transmission wheel 512 is in an idle state, that is, the second transmission wheel 512 will not drive the wheel 20 to rotate. When the first incomplete transmission wheel 513 is meshed with the second transmission wheel 512, the second transmission wheel 512 can also drive the wheel 20 to rotate forward or reversely, and the first incomplete transmission wheel 513 and the first transmission wheel 511 are in a non-transmission matching state, at which time the first transmission wheel 511 is in an idle state, that is, the first transmission wheel 511 does not drive the wheel 20 to rotate. Through the matching of the first transmission wheel 511, the second transmission wheel 512 and the first incomplete transmission wheel 513, the wheel 20 can rotate forward or reversely, so that the wheel 20 can continuously move forward or backward.

[0042] For further information, please also refer to Figures 2 to 5 As a specific implementation of the balance vehicle provided by the first embodiment of the present invention, specifically, the first transmission wheel 511 and the second transmission wheel 512 are symmetrically arranged on opposite sides of the first incomplete transmission wheel 513. Preferably, in this embodiment, the first incomplete transmission wheel 513 can be an incomplete gear or an incomplete chain plate, and the first transmission wheel 511 and the second transmission wheel 512 can be gears. The maximum tooth spacing of the first incomplete transmission wheel 513 is greater than the minimum tooth spacing between the first transmission wheel 511 and the second transmission wheel 512, so as to ensure that the first incomplete transmission wheel 513 can only mesh with the first transmission wheel 511 or the second transmission wheel 512, and will not be disengaged from the first transmission wheel 511 and the second transmission wheel 512 at the same time, thereby ensuring the reliability of movement.

[0043] For further information, please also refer to Figures 2 to 5As a specific implementation of the balancing vehicle provided by the first embodiment of the present invention, the reset mechanism 60 includes a third transmission wheel 611, a fourth transmission wheel 612, a first transmission belt 613 and a first reversing wheel 614. The third transmission wheel 611 is coaxially connected and fixed with the first transmission wheel 511, and the fourth transmission wheel 612 is coaxially connected and fixed with the second transmission wheel 512. The first transmission belt 613 connects the third transmission wheel 611 and the fourth transmission wheel 612, and the first reversing wheel 614 is used to support the first transmission belt 613, one end of the first transmission belt 613 is connected and fixed with the first pedal 30, and the other end is connected and fixed with the second pedal 40. Through the setting of the reset mechanism 60, the first pedal 30 and the second pedal 40 can achieve reverse swing. Preferably, the third transmission wheel 611 and the fourth transmission wheel 612 are gears, and the first transmission belt 613 is a chain.

[0044] The working principle of the balancing vehicle of the first embodiment of the present invention is as follows:

[0045] When the first pedal 30 is stepped on downward, the third transmission wheel 611 is driven to rotate in the opposite direction through the first transmission belt 613, and the third transmission wheel 611 drives the first transmission wheel 511 to rotate in the opposite direction, thereby driving the first incomplete transmission wheel 513 to rotate forward, thereby driving the wheel 20 to rotate forward. Due to the driving of the reset mechanism 60, when the first pedal 30 moves downward, the second pedal 40 moves upward. When the first pedal 30 moves to the lowest point of the stroke, the second pedal 40 is located at the highest point of the stroke. At this time, the first incomplete transmission wheel 513 is separated from the first transmission wheel 511 due to inertia and cooperates with the second transmission wheel 512. At this time, the second pedal 40 is continued to be stepped on downward, and the fourth transmission wheel 612 is driven to rotate in the opposite direction through the first transmission belt 613. The fourth transmission wheel 612 drives the second transmission wheel 512 to rotate in the opposite direction, thereby driving the first incomplete transmission wheel 513 to rotate forward, thereby driving the wheel 20 to rotate forward. Driven by the reset mechanism 60, when the second pedal 40 moves to the lowest point of the stroke, the first pedal 30 is located at the highest point of the stroke. At this time, the first incomplete transmission wheel 513 is separated from the second transmission wheel 512 due to inertia and re-engages with the first transmission wheel 511, completing an alternating process. By repeatedly stepping on the first pedal 30 and the second pedal 40, the continuous advancement of the wheel 20 is achieved.

[0046] The reversing operation of the balancing vehicle of the first embodiment of the present invention is divided into two cases, the first is reversing at the meshing position, and the second is reversing at the alternating position. Among them, the meshing position refers to the position when the first incomplete transmission wheel 513 is meshed with the first transmission wheel 511 or the first incomplete transmission wheel 513 is meshed with the second transmission wheel 512. The alternating position refers to the position where the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point or the first pedal 30 is at the lowest point and the second pedal 40 is at the highest point, that is, at this time, the first incomplete transmission wheel 513 is at the critical position for meshing with the first transmission wheel 511 and the second transmission wheel 512. The specific principle is as follows:

[0047] When the first incomplete transmission wheel 513 is meshed with the first transmission wheel 511 , at this time, the first incomplete transmission wheel 513 and the second transmission wheel 512 are in a state of non-transmission cooperation, that is, the second transmission wheel 512 is in an idling state. If the first pedal 30 is stepped on downward, the first pedal 30 drives the third transmission wheel 611 to rotate in the opposite direction through the first transmission belt 613, so that the first transmission wheel 511 coaxially fixed with the third transmission wheel 611 rotates in the opposite direction, thereby driving the first incomplete transmission wheel 513 to rotate forward, and then driving the wheel 20 to rotate forward, realizing forward operation; if the second pedal 40 is stepped on downward, the second pedal 40 drives the third transmission wheel 611 to rotate forward through the first transmission belt 613, so that the first transmission wheel 511 coaxially fixed with the third transmission wheel 611 rotates forward, thereby driving the first incomplete transmission wheel 513 to rotate in the opposite direction, and then driving the wheel 20 to rotate in the opposite direction, realizing backward operation, so that when the first incomplete transmission wheel 513 and the first transmission wheel 511 are in the meshing position, the rotation direction of the wheel 20 can be changed by stepping on different pedals, and the reversing operation is very simple and convenient.

[0048] When the first incomplete transmission wheel 513 is meshed with the second transmission wheel 512 , at this time, the first incomplete transmission wheel 513 and the first transmission wheel 511 are in a state of non-transmission cooperation, that is, the first transmission wheel 511 is in an idling state. If the second pedal 40 is stepped on downward, the second pedal 40 drives the fourth transmission wheel 612 to rotate in the opposite direction through the first transmission belt 613, so that the second transmission wheel 512 coaxially fixed with the fourth transmission wheel 612 rotates in the opposite direction, thereby driving the first incomplete transmission wheel 513 to rotate forward, and then driving the wheel 20 to rotate forward, realizing forward operation; if the first pedal 30 is stepped on downward, the first pedal 30 drives the fourth transmission wheel 612 to rotate forward through the first transmission belt 613, so that the second transmission wheel 512 coaxially fixed with the fourth transmission wheel 612 rotates forward, thereby driving the first incomplete transmission wheel 513 to rotate in the opposite direction, and then driving the wheel 20 to rotate in the opposite direction, realizing backward operation, so that when the first incomplete transmission wheel 513 and the second transmission wheel 512 are in the meshing position, the rotation direction of the wheel 20 can be changed by stepping on different pedals, and the reversing operation is very simple and convenient.

[0049] When the first incomplete transmission wheel 513 is in an alternating position with the first transmission wheel 511 and the second transmission wheel 512, the direction of rotation of the wheel 20 can be changed by using the center of gravity. The user only needs to twist the body forward or backward to change the direction of rotation of the wheel 20.

[0050] For further information, please also refer to Figures 1 to 6 As a specific implementation of the balance vehicle provided by the first embodiment of the present invention, the balance vehicle further includes a differential mechanism 70. Through the setting of the differential mechanism 70, the differential motion of the two wheels 20 can be realized. The differential mechanism 70 includes a differential shaft 71, a differential 72 arranged on the differential shaft 71, and a transmission wheel set 73 for driving the differential 72 to rotate. The two ends of the differential shaft 71 are respectively connected to each wheel 20, and the transmission wheel set 73 is connected to the incomplete transmission wheel assembly 50. Specifically, in this embodiment, the transmission wheel set 73 is connected to the first incomplete transmission wheel 513, so that the movement of the first incomplete transmission wheel 513 can be transmitted to each wheel 20, so as to realize the continuous forward, backward or reversing operation of the balance vehicle. Preferably, the transmission wheel set 73 includes a fifth transmission wheel 731, a sixth transmission wheel 732 and a fourth transmission belt 733 for transmission connection between the fifth transmission wheel 731 and the sixth transmission wheel 732, the fifth transmission wheel 731 is coaxially fixed with the first incomplete transmission wheel 513, and the sixth transmission wheel 732 is coaxially fixed with the differential 72.

[0051] For further information, see Figure 1As a specific implementation of the balance vehicle provided by the first embodiment of the present invention, the balance vehicle further includes a seat cushion 80. Through the arrangement of the seat cushion 80, the user can improve the balance during riding and ride more comfortably. Specifically, the vehicle body 10 includes a vertical rod 11, and the seat cushion 80 is installed at the top of the vertical rod 11.

[0052] For further information, see Figure 1 As a specific implementation of the balance car provided by the first embodiment of the present invention, the balance car also includes a brake device 90, which includes two brake pads 911 respectively installed on the corresponding wheels 20, and two brake handles 912 respectively corresponding to each brake pad 911 and used to control each brake pad 911 to contact or separate from the corresponding wheel 20. Through the control of the brake device 90, braking and reversing operations can be achieved. Specifically, the brake handle 912 is installed on the vehicle body 10. Preferably, the brake handle 912 is installed on the vertical rod 11. When braking is needed, the braking operation of the corresponding wheel 20 can be achieved by swinging the leg to touch the brake handle 912. The operation is very simple and convenient.

[0053] Example 2

[0054] Please also read Figures 7 to 10 The structure of the balancing vehicle provided by the second embodiment of the present invention is basically the same as that of the balancing vehicle provided by the first embodiment of the present invention, except that:

[0055] In this embodiment, the incomplete transmission wheel assembly 50 includes a first transmission bar 521, a second transmission bar 522, a second incomplete transmission wheel 523 and a third incomplete transmission wheel 524. The first transmission bar 521 is connected to the first pedal 30, the second transmission bar 522 is connected to the second pedal 40, the second incomplete transmission wheel 523 is rotatably mounted on the vehicle body 10, and the third incomplete transmission wheel 524 is coaxially connected and fixed with the second incomplete transmission wheel 523 and is symmetrically arranged up and down. The first transmission bar 521 is meshed with the second incomplete transmission wheel 523, and the second transmission bar 522 is meshed with the third incomplete transmission wheel 524. Specifically, when the first transmission bar 521 is disengaged from the second incomplete transmission wheel 523, the second transmission bar 522 begins to mesh with the third incomplete transmission wheel 524, and when the first transmission bar 521 is meshed with the second incomplete transmission wheel 523, the second transmission bar 522 begins to disengage from the third incomplete transmission wheel 524. Through the cooperation of the first transmission bar 521 , the second transmission bar 522 , the second incomplete transmission wheel 523 and the third incomplete transmission wheel 524 , the forward rotation or reverse rotation of the wheel 20 is achieved, so that the wheel 20 continuously moves forward or backward.

[0056] For further information, please also refer to Figures 7 to 9As a specific implementation of the balancing vehicle provided by the second embodiment of the present invention, the second incomplete transmission wheel 523 and the third incomplete transmission wheel 524 can be incomplete gears or incomplete chain plates, and the first transmission bar 521 and the second transmission bar 522 can be racks or chains. Specifically, the first transmission bar 521 and the second transmission bar 522 are arc-shaped.

[0057] For further information, please also refer to Figures 7 to 9 As a specific implementation of the balancing vehicle provided in the second embodiment of the present invention, the reset mechanism 60 includes a second transmission belt 621 and a second reversing wheel 622 disposed on the vehicle body 10 and used to support the second transmission belt 621. One end of the second transmission belt 621 is connected and fixed to the first pedal 30, and the other end is connected and fixed to the second pedal 40. Through the arrangement of the reset mechanism 60, the first pedal 30 and the second pedal 40 can achieve reverse swing. Preferably, the second transmission belt 621 is a chain or a rope.

[0058] For further information, please also refer to Figures 7 to 9 As a specific implementation of the balancing vehicle provided by the second embodiment of the present invention, the second reversing wheel 622 is fixed to the vehicle body 10 by a first adjusting screw 623. By setting the first adjusting screw 623, the meshing position of the first transmission bar 521 and the second transmission bar 522 can be adjusted, so that when the first transmission bar 521 is disengaged from the second incomplete transmission wheel 523, the second transmission bar 522 starts to mesh with the third incomplete transmission wheel 524, and when the first transmission bar 521 is engaged with the second incomplete transmission wheel 523, the second transmission bar 522 starts to disengage from the third incomplete transmission wheel 524.

[0059] The working principle of the balancing vehicle of the second embodiment of the present invention is as follows:

[0060] When the first transmission bar 521 is meshed with the second incomplete transmission wheel 523, the second transmission bar 522 is disengaged from the third incomplete transmission wheel 524, that is, the second transmission bar 522 and the third incomplete transmission wheel 524 are in a state of no transmission cooperation, that is, the second transmission bar 522 will not drive the third incomplete transmission wheel 524 to rotate, and at this time, the third incomplete transmission wheel 524 is in an idle rotation state. When the first pedal 30 is stepped down, the second incomplete transmission wheel 523 is driven to rotate forwardly through the first transmission bar 521, thereby driving the wheel 20 to rotate forwardly. Due to the driving of the reset mechanism 60, when the first pedal 30 moves downward, the second pedal 40 moves upward. When the first pedal 30 moves to the lowest point of the stroke, the second pedal 40 is at the highest point of the stroke, at which time the first transmission bar 521 disengages from the second incomplete transmission wheel 523, and the second transmission bar 522 begins to mesh with the third incomplete transmission wheel 524. At this time, the second pedal 40 is continuously stepped downward, and the third incomplete transmission wheel 524 is driven to rotate forward through the second transmission bar 522, thereby driving the wheel 20 to rotate forward. When the second pedal 40 moves to the lowest point of the stroke, the first pedal 30 is at the highest point of the stroke, and at this time the first transmission bar 521 begins to mesh with the second incomplete transmission wheel 523 again, and the second transmission bar 522 disengages from the third incomplete transmission wheel 524, completing an alternating process. By repeatedly stepping on the first pedal 30 and the second pedal 40, the wheel 20 can continuously move forward.

[0061] The reversing operation of the balance vehicle of the second embodiment of the present invention is divided into two cases, the first is reversing at the meshing position, and the second is reversing at the alternating position. Among them, the meshing position refers to the position when the first transmission bar 521 is meshed with the second incomplete transmission wheel 523 or the second transmission bar 522 is meshed with the third incomplete transmission wheel 524. The alternating position refers to the position where the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point or the first pedal 30 is at the lowest point and the second pedal 40 is at the highest point, that is, at this time, the first transmission bar 521 and the second incomplete transmission wheel 523 are in meshing and non-meshing, and the second transmission bar 522 and the third incomplete transmission wheel 524 are at the junction of meshing and non-meshing. The specific principle is as follows:

[0062] When the first transmission bar 521 is meshed with the second incomplete transmission wheel 523, at this time, the second transmission bar 522 is disengaged from the third incomplete transmission wheel 524, that is, the second transmission bar 522 and the third incomplete transmission wheel 524 are in a state of no transmission cooperation, that is, the second transmission bar 522 will not drive the third incomplete transmission wheel 524 to rotate, and at this time, the third incomplete transmission wheel 524 is in an idling state. If the first pedal 30 is stepped on downward, the first pedal 30 drives the second incomplete drive wheel 523 to rotate forward through the first transmission bar 521, and then drives the wheel 20 to rotate forward, realizing forward operation; if the second pedal 40 is stepped on downward, the second pedal 40 drives the first pedal 30 to move upward through the reset mechanism 60, and the first transmission bar 521 drives the second incomplete drive wheel 523 to rotate reversely, and then drives the wheel 20 to rotate reversely, realizing backward operation, so that when the first transmission bar 521 is engaged with the second incomplete drive wheel 523, the rotation direction of the wheel 20 can be changed by stepping on different pedals, and the reversing operation is very simple and convenient.

[0063] When the second transmission bar 522 is meshed with the third incomplete transmission wheel 524, the first transmission bar 521 is disengaged from the second incomplete transmission wheel 523, that is, the first transmission bar 521 and the second incomplete transmission wheel 523 are in a state of no transmission matching, that is, the second incomplete transmission wheel 523 is in an idle state. If the second pedal 40 is stepped down, the second pedal 40 drives the third incomplete transmission wheel 524 to rotate forward through the second transmission bar 522, and then drives the wheel 20 to rotate forward, so as to realize the forward operation; if the first pedal 30 is stepped down, the first pedal 30 drives the second pedal 40 to move upward through the reset mechanism 60, and the second transmission bar 522 drives the third incomplete transmission wheel 524 to rotate in the opposite direction, and then drives the wheel 20 to rotate in the opposite direction, so as to realize the backward operation, so that when the second transmission bar 522 and the third incomplete transmission wheel 524 are in the meshing position, the rotation direction of the wheel 20 can be changed by stepping on different pedals, and the reversing operation is very simple and convenient.

[0064] When the first transmission bar 521 or the second transmission bar 522 is in an alternating position, the direction of rotation of the wheel 20 can be changed by using the center of gravity. The user only needs to twist the body forward or backward to change the direction of rotation of the wheel 20 .

[0065] For further information, please also refer to Figures 7 to 9As a specific implementation of the balancing vehicle provided by the second embodiment of the present invention, a stopper 624 is provided on the vehicle body 10 for preventing the first transmission bar 521 from sliding out of the second incomplete transmission wheel 523 and the second transmission bar 522 from sliding out of the third incomplete transmission wheel 524. The stopper 624 is located above the first pedal 30 and the second pedal 40. When the first pedal 30 or the second pedal 40 moves upward to the position of the stopper 624, the first pedal 30 or the second pedal 40 cannot continue to move upward due to the obstruction of the stopper 624, thereby playing a limiting role and preventing the first transmission bar 521 or the second transmission bar 522 from sliding out of the meshing position due to inertia.

[0067] Please also read Figures 11 to 14 The structure of the balancing vehicle provided by the third embodiment of the present invention is basically the same as that of the balancing vehicle provided by the second embodiment of the present invention, except that:

[0068] In this embodiment, the reset mechanism 60 includes a fourth incomplete transmission wheel 631, a fifth incomplete transmission wheel 632, a third transmission bar 633, and a fourth transmission bar 634. The fourth incomplete transmission wheel 631 is coaxially connected and fixed to the second incomplete transmission wheel 523, and the fifth incomplete transmission wheel 632 is coaxially connected and fixed to the third incomplete transmission wheel 524. The third transmission bar 633 meshes with a side of the fourth incomplete transmission wheel 631 away from the first transmission bar 521, and the fourth transmission bar 634 meshes with a side of the fifth incomplete transmission wheel 632 away from the second transmission bar 522. When the lowest point of the first transmission bar 521 and the second incomplete transmission wheel 523 are located at alternating positions, the lowest point of the third transmission bar 633 and the fourth incomplete transmission wheel 631 are located at alternating positions, and the highest point of the second transmission bar 522 and the third incomplete transmission wheel 524 are located at alternating positions, and the highest point of the fourth transmission bar 634 and the fifth incomplete transmission wheel 632 are located at alternating positions; when the highest point of the first transmission bar 521 and the second incomplete transmission wheel 523 are located at alternating positions, the highest point of the third transmission bar 633 and the fourth incomplete transmission wheel 631 are located at alternating positions, and the lowest point of the second transmission bar 522 and the third incomplete transmission wheel 524 are located at alternating positions, and the lowest point of the fourth transmission bar 634 and the fifth incomplete transmission wheel 632 are located at alternating positions.

[0069] Among them, the alternating position refers to: the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point, or the first pedal 30 is at the lowest point and the second pedal 40 is at the highest point, that is, the first transmission bar 521 and the second incomplete transmission wheel 523 are in meshing and non-meshing, the second transmission bar 522 and the third incomplete transmission wheel 524 are in meshing and non-meshing, the third transmission bar 633 and the fourth incomplete transmission wheel 631 are in meshing and non-meshing, and the fourth transmission bar 634 and the fifth incomplete transmission wheel 632 are at the junction of meshing and non-meshing.

[0070] The working principle of the balancing vehicle of the third embodiment of the present invention is as follows:

[0071] When the first transmission bar 521 is meshed with the second incomplete transmission wheel 523, the fourth transmission bar 634 is meshed with the fifth incomplete transmission wheel 632, the second transmission bar 522 is disengaged from the third incomplete transmission wheel 524, and the third transmission bar 633 is disengaged from the fourth incomplete transmission wheel 631, that is, the second transmission bar 522 and the third incomplete transmission wheel 524, the third transmission bar 633 and the fourth incomplete transmission wheel 631 are in a state of no transmission cooperation, that is, the second transmission bar 522 will not drive the third incomplete transmission wheel 524 to rotate, and the third transmission bar 633 will not drive the fourth incomplete transmission wheel 631 to rotate, at this time, the third incomplete transmission wheel 524 and the fourth incomplete transmission wheel 631 are in an idle rotation state. When the first pedal 30 is stepped down, the second incomplete transmission wheel 523 is driven to rotate forwardly through the first transmission bar 521, thereby driving the wheel 20 to rotate forwardly. Since the fifth incomplete transmission wheel 632 is coaxially fixed with the second incomplete transmission wheel 523, the fifth incomplete transmission wheel 632 rotates synchronously in the positive direction, thereby driving the fourth transmission bar 634 to move upward, and further causing the second pedal 40 to move upward. When the first pedal 30 moves to the lowest point of the stroke, the second pedal 40 is located at the highest point of the stroke, at which time the first transmission bar 521 is disengaged from the second incomplete transmission wheel 523, the fourth transmission bar 634 is disengaged from the fifth incomplete transmission wheel 632, and the second transmission bar 522 begins to mesh with the third incomplete transmission wheel 524, and the third transmission bar 633 begins to mesh with the fourth incomplete transmission wheel 631.

[0072] When the first transmission bar 521 is disengaged from the second incomplete transmission wheel 523, the third transmission bar 633 is meshed with the fourth incomplete transmission wheel 631, and the second transmission bar 522 is meshed with the third incomplete transmission wheel 524, and the fourth transmission bar 634 is disengaged from the fifth incomplete transmission wheel 632, that is, the first transmission bar 521 and the second incomplete transmission wheel 523, the fourth transmission bar 634 and the fifth incomplete transmission wheel 632 are in a state of no transmission cooperation, that is, the first transmission bar 521 will not drive the second incomplete transmission wheel 523 to rotate, and the fourth transmission bar 634 will not drive the fifth incomplete transmission wheel 632 to rotate. At this time, the second incomplete transmission wheel 523 and the fifth incomplete transmission wheel 632 are in an idling state. When the second pedal 40 is continuously stepped on downward, the third incomplete transmission wheel 524 is driven to rotate forward through the second transmission bar 522, thereby driving the wheel 20 to rotate forward. Since the fourth incomplete transmission wheel 631 is coaxially fixed with the third incomplete transmission wheel 524, the fourth incomplete transmission wheel 631 rotates forward synchronously, thereby driving the third transmission bar 633 to move upward, thereby causing the first pedal 30 to move upward, completing an alternating process. By repeatedly stepping on the first pedal 30 and the second pedal 40, the wheel 20 can move forward continuously.

[0073] The reversing operation of the balance vehicle of the third embodiment of the present invention is divided into two cases, the first is reversing at the meshing position, and the second is reversing at the alternating position. Among them, the meshing position refers to: when the first transmission bar 521 is meshed with the second incomplete transmission wheel 523, the fourth transmission bar 634 is meshed with the fifth incomplete transmission wheel 632, the second transmission bar 522 is disengaged from the third incomplete transmission wheel 524, and the third transmission bar 633 is disengaged from the fourth incomplete transmission wheel 631; or, the first transmission bar 521 is disengaged from the second incomplete transmission wheel 523, the third transmission bar 633 is meshed with the fourth incomplete transmission wheel 631, and the second transmission bar 522 is meshed with the third incomplete transmission wheel 524, and the fourth transmission bar 634 is disengaged from the fifth incomplete transmission wheel 632. The specific principle is as follows:

[0074] When the first transmission bar 521 is meshed with the second incomplete transmission wheel 523, the fourth transmission bar 634 is meshed with the fifth incomplete transmission wheel 632, the second transmission bar 522 is disengaged from the third incomplete transmission wheel 524, and the third transmission bar 633 is disengaged from the fourth incomplete transmission wheel 631. If the first pedal 30 is stepped on downward, the first pedal 30 drives the second incomplete transmission wheel 523 to rotate forward through the first transmission bar 521, thereby driving the wheel 20 to rotate forward, thereby realizing forward operation; if the second pedal 40 is stepped on downward, the second pedal 40 drives the fourth transmission bar 634 to move downward, thereby driving the fifth incomplete transmission wheel 632 to rotate in the opposite direction, thereby driving the wheel 20 to rotate in the opposite direction, thereby realizing backward operation, so that when the first transmission bar 521 is meshed with the second incomplete transmission wheel 523, the rotation direction of the wheel 20 can be changed by stepping on different pedals, and the reversing operation is very simple and convenient.

[0075] When the second transmission bar 522 is meshed with the third incomplete transmission wheel 524, the third transmission bar 633 is meshed with the fourth incomplete transmission wheel 631, the first transmission bar 521 is disengaged from the second incomplete transmission wheel 523, and the fourth transmission bar 634 is disengaged from the fifth incomplete transmission wheel 632. If the second pedal 40 is stepped on downward, the second pedal 40 drives the third incomplete transmission wheel 524 to rotate forward through the second transmission bar 522, thereby driving the wheel 20 to rotate forward, thereby realizing forward operation; if the first pedal 30 is stepped on downward, the first pedal 30 drives the third transmission bar 633 to move downward, thereby driving the fourth incomplete transmission wheel 631 to rotate in the opposite direction, thereby driving the wheel 20 to rotate in the opposite direction, thereby realizing backward operation, so that when the second transmission bar 522 is in the meshing position with the third incomplete transmission wheel 524, the direction of the wheel 20 can be changed by stepping on different pedals, and the reversing operation is very simple and convenient.

[0076] When the first transmission bar 521 or the second transmission bar 522 is in an alternating position, the direction of rotation of the wheel 20 can be changed by using the center of gravity. The user only needs to twist the body forward or backward to change the direction of rotation of the wheel 20 .

[0077] For further information, please also refer to Figures 11 to 14 As a specific implementation of the balancing vehicle provided by the third embodiment of the present invention, the fourth incomplete transmission wheel 631 and the fifth incomplete transmission wheel 632 can be incomplete gears or incomplete chain plates, and the third transmission bar 633 and the fourth transmission bar 634 can be racks or chains. Specifically, the third transmission bar 633 and the fourth transmission bar 634 are arc-shaped.

[0078] Example 4

[0079] Please also read Figures 15 to 17The structure of the balancing vehicle provided by the fourth embodiment of the present invention is basically the same as that of the balancing vehicle provided by the first embodiment of the present invention, except that:

[0080] In this embodiment, the incomplete transmission wheel assembly 50 includes a sixth incomplete transmission wheel 531, a fifth transmission bar 532 and a sixth transmission bar 533. The sixth incomplete transmission wheel 531 is rotatably mounted on the vehicle body 10. The fifth transmission bar 532 and the sixth transmission bar 533 are respectively arranged on opposite sides of the sixth incomplete transmission wheel 531. The sixth incomplete transmission wheel 531 is meshed with the fifth transmission bar 532 or the sixth transmission bar 533. When the fifth transmission bar 532 begins to disengage from the sixth incomplete transmission wheel 531, the sixth transmission bar 533 begins to mesh with the sixth incomplete transmission wheel 531. When the fifth transmission bar 532 begins to mesh with the sixth incomplete transmission wheel 531, the sixth transmission bar 533 begins to disengage from the sixth incomplete transmission wheel 531. Through the cooperation of the sixth incomplete transmission wheel 531, the fifth transmission bar 532 and the sixth transmission bar 533, the positive rotation or reverse rotation of the wheel 20 is realized, so that the wheel 20 continues to move forward or backward. The reset mechanism 60 includes a third transmission belt 641 and a third reversing wheel 642 disposed on the vehicle body 10 and used to support the third transmission belt 641. One end of the third transmission belt 641 is connected and fixed to the first pedal 30, and the other end is connected and fixed to the second pedal 40. Through the arrangement of the reset mechanism 60, the first pedal 30 and the second pedal 40 can achieve reverse swing.

[0081] Preferably, in this embodiment, the sixth incomplete transmission wheel 531 can be an incomplete gear or an incomplete chain plate, the fifth transmission bar 532 and the sixth transmission bar 533 can be racks or chains, and the third transmission belt 641 can be a chain or a rope.

[0082] The working principle of the balancing vehicle of the fourth embodiment of the present invention is as follows:

[0083] When the fifth transmission bar 532 is meshed with the sixth incomplete transmission wheel 531, the sixth transmission bar 533 is disengaged from the sixth incomplete transmission wheel 531, that is, the sixth transmission bar 533 and the sixth incomplete transmission wheel 531 are in a non-transmission matching state, and the sixth transmission bar 533 will not interfere with the rotation of the sixth incomplete transmission wheel 531. When the first pedal 30 is stepped down, the sixth incomplete transmission wheel 531 is driven to rotate forwardly through the fifth transmission bar 532, thereby driving the wheel 20 to rotate forwardly. And due to the setting of the third transmission belt 641, when the first pedal 30 moves downward, the second pedal 40 is driven to move upward. When the first pedal 30 moves to the lowest point of the stroke, the second pedal 40 is at the highest point of the stroke, at which time the fifth transmission bar 532 begins to disengage from the sixth incomplete transmission wheel 531, and the sixth transmission bar 533 begins to mesh with the sixth incomplete transmission wheel 531. At this time, the second pedal 40 is continuously stepped downward, and the first pedal 30 is driven upward through the third transmission belt 641, so that the fifth transmission bar 532 and the sixth transmission bar 533 move upward at the same time. At this time, the sixth transmission bar 533 drives the sixth incomplete transmission wheel 531 to rotate forward, thereby driving the wheel 20 to rotate forward. When the second pedal 40 moves to the lowest point of the stroke, the first pedal 30 is at the highest point of the stroke, and at this time the sixth incomplete transmission wheel 531 is disengaged from the sixth transmission bar 533 due to inertia and re-engages with the fifth transmission bar 532, completing an alternating process, so that the wheel 20 can be continuously advanced by repeatedly stepping on the first pedal 30 and the second pedal 40.

[0084] The reversing operation of the balancing vehicle of the fourth embodiment of the present invention is divided into two cases, the first is reversing at the meshing position, and the second is reversing at the alternating position. Among them, the meshing position refers to the position when the fifth transmission bar 532 is meshed with the sixth incomplete transmission wheel 531 or the sixth transmission bar 533 is meshed with the sixth incomplete transmission wheel 531. The alternating position refers to the position where the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point or the first pedal 30 is at the lowest point and the second pedal 40 is at the highest point, that is, at this time, the fifth transmission bar 532 and the sixth incomplete transmission wheel 531 are in meshing and non-meshing, and the sixth transmission bar 533 and the sixth incomplete transmission wheel 531 are at the junction of meshing and non-meshing. The specific reversing principle is as follows:

[0085] When the fifth transmission bar 532 is meshed with the sixth incomplete transmission wheel 531, the sixth transmission bar 533 is disengaged from the sixth incomplete transmission wheel 531. If the first pedal 30 is stepped on downward, the sixth incomplete transmission wheel 531 is driven to rotate forwardly through the fifth transmission bar 532, thereby driving the wheel 20 to rotate forwardly, and realizing forward operation; if the second pedal 40 is stepped on downward, the second pedal 40 drives the fifth transmission bar 532 to move upwardly through the third transmission belt 641, thereby causing the sixth incomplete transmission wheel 531 to rotate in the opposite direction, thereby driving the wheel 20 to rotate in the opposite direction, and realizing backward operation, so that when the fifth transmission bar 532 is in the meshing position with the sixth incomplete transmission wheel 531, the rotation direction of the wheel 20 can be changed by stepping on different pedals, and the reversing operation is very simple and convenient.

[0086] When the sixth transmission bar 533 is meshed with the sixth incomplete transmission wheel 531, the fifth transmission bar 532 is disengaged from the sixth incomplete transmission wheel 531. If the second pedal 40 is stepped on downward, the second pedal 40 drives the sixth transmission bar 533 to move upward through the third transmission belt 641, so that the sixth incomplete transmission wheel 531 rotates forward, and then drives the wheel 20 to rotate forward, realizing forward operation; if the first pedal 30 is stepped on downward, the first pedal 30 drives the sixth transmission bar 533 to move downward, so that the sixth incomplete transmission wheel 531 rotates in the opposite direction, and then drives the wheel 20 to rotate in the opposite direction, realizing backward operation, so that when the sixth transmission bar 533 is in the meshing position with the sixth incomplete transmission wheel 531, the rotation direction of the wheel 20 can be changed by stepping on different pedals, and the reversing operation is very simple and convenient.

[0087] When in the alternating position, the direction of rotation of the wheel 20 can be changed by utilizing the center of gravity. The user only needs to twist the body forward or backward to change the direction of rotation of the wheel 20 .

[0104] If the eighth transmission bar 5413 drives the seventh incomplete transmission wheel 5411 to rotate in the opposite direction, and the ninth transmission bar 5422 drives the eighth incomplete transmission wheel 5421 to rotate in the opposite direction, then both wheels 20 rotate in the opposite direction, and at this time, the balancing vehicle moves backward.

[0105] When the second pedal 40 moves downward from the highest point, due to the setting of the reset mechanism 60, the first pedal 30 moves upward from the lowest point; at this time, the balance vehicle has the following four motion states.

[0106] If the ninth transmission bar 5422 drives the eighth incomplete transmission wheel 5421 to rotate forwardly, and the seventh transmission bar 5412 drives the seventh incomplete transmission wheel 5411 to rotate reversely, the two wheels 20 rotate in opposite directions. At this time, the balancing vehicle rotates in place.

[0107] If the ninth transmission bar 5422 drives the eighth incomplete transmission wheel 5421 to rotate forward, and the eighth transmission bar 5413 drives the seventh incomplete transmission wheel 5411 to rotate forward, then both wheels 20 rotate forward, and the balancing vehicle moves forward.

[0108] If the tenth transmission bar 5423 drives the eighth incomplete transmission wheel 5421 to rotate in the opposite direction, and the seventh transmission bar 5412 drives the seventh incomplete transmission wheel 5411 to rotate in the opposite direction, then both wheels 20 rotate in the opposite direction, and at this time, the balancing vehicle moves backward.

[0109] If the tenth transmission bar 5423 drives the eighth incomplete transmission wheel 5421 to rotate in the reverse direction, and the eighth transmission bar 5413 drives the seventh incomplete transmission wheel 5411 to rotate in the forward direction, the two wheels 20 rotate in opposite directions. At this time, the balancing vehicle rotates in place.

[0110] In the embodiment of the present invention, the first pedal 30 and the second pedal 40 can move up and down to realize the forward, backward or in-situ rotation operation of the balancing vehicle.

[0111] The working process of the positive rotation of the wheel 20 on the same side as the first pedal 30 is as follows:

[0112] When the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point, the seventh incomplete transmission wheel 5411 and the eighth incomplete transmission wheel 5421 are at alternating positions, wherein the alternating positions refer to: the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point or the first pedal 30 is at the lowest point and the second pedal 40 is at the highest point. That is, the seventh transmission bar 5412 and the seventh incomplete transmission wheel 5411 are in meshing and non-meshing, the eighth transmission bar 5413 and the seventh incomplete transmission wheel 5411 are in meshing and non-meshing, the ninth transmission bar 5422 and the eighth incomplete transmission wheel 5421 are in meshing and non-meshing, and the tenth transmission bar 5423 and the eighth incomplete transmission wheel 5421 are in meshing and non-meshing intersection. If the user steps on the first pedal 30, the second pedal 40 moves upward, and the first pedal 30 simultaneously drives the seventh transmission bar 5412 and the eighth transmission bar 5413 to move downward. If the seventh transmission bar 5412 is engaged with the seventh incomplete transmission wheel 5411, and the eighth transmission bar 5413 is disengaged from the seventh incomplete transmission wheel 5411, the seventh transmission bar 5412 drives the seventh incomplete transmission wheel 5411 to rotate forward, and the eighth transmission bar 5413 does not work. When the second pedal 40 moves to the highest point and the first pedal 30 moves to the lowest point, at this time, the seventh transmission bar 5412 begins to disengage from the seventh incomplete transmission wheel 5411, and the eighth transmission bar 5413 begins to engage with the seventh incomplete transmission wheel 5411, and the second pedal 40 continues to be stepped on downward. At this time, the first pedal 30 moves upward, and the first pedal 30 simultaneously drives the seventh transmission bar 5412 and the eighth transmission bar 5413 to move upward. At this time, the eighth transmission bar 5413 drives the seventh incomplete transmission wheel 5411 to rotate forward, and the seventh transmission bar 5412 does not work, thereby completing an alternating process of forward rotation of the wheel 20, and the continuous advancement of the wheel 20 is achieved by repeatedly stepping on the first pedal 30 and the second pedal 40.

[0113] The working process of the reverse rotation of the wheel 20 on the same side as the first pedal 30 is as follows:

[0114] When the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point, if the user steps on the first pedal 30, the second pedal 40 moves upward, and the first pedal 30 simultaneously drives the seventh transmission bar 5412 and the eighth transmission bar 5413 to move downward. If the eighth transmission bar 5413 is engaged with the seventh incomplete transmission wheel 5411 and the seventh transmission bar 5412 is disengaged from the seventh incomplete transmission wheel 5411, the eighth transmission bar 5413 drives the seventh incomplete transmission wheel 5411 to rotate in the opposite direction, and the seventh transmission bar 5412 does not work. When the second pedal 40 moves to the highest point and the first pedal 30 moves to the lowest point, at this time, the eighth transmission bar 5413 begins to disengage from the seventh incomplete transmission wheel 5411, and the seventh transmission bar 5412 begins to engage with the seventh incomplete transmission wheel 5411, and the second pedal 40 continues to be stepped on downward. At this time, the first pedal 30 moves upward, and the first pedal 30 simultaneously drives the seventh transmission bar 5412 and the eighth transmission bar 5413 to move upward. At this time, the seventh transmission bar 5412 drives the seventh incomplete transmission wheel 5411 to rotate in the opposite direction, and the eighth transmission bar 5413 does not work, thereby completing an alternating process of reverse rotation of the wheel 20, and the continuous retreat of the wheel 20 is achieved by repeatedly stepping on the first pedal 30 and the second pedal 40.

[0115] The working process of the positive rotation of the wheel 20 on the same side as the second pedal 40 is as follows:

[0116] When the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point, if the user steps on the first pedal 30, the second pedal 40 moves upward, and the second pedal 40 drives the ninth transmission bar 5422 and the tenth transmission bar 5423 to move upward. If the tenth transmission bar 5423 is engaged with the eighth incomplete transmission wheel 5421 and the ninth transmission bar 5422 is disengaged from the eighth incomplete transmission wheel 5421, the tenth transmission bar 5423 drives the eighth incomplete transmission wheel 5421 to rotate forward, and the ninth transmission bar 5422 does not work. When the second pedal 40 moves to the highest point and the first pedal 30 moves to the lowest point, at this time, the tenth transmission bar 5423 begins to disengage from the eighth incomplete transmission wheel 5421, and the ninth transmission bar 5422 begins to engage with the eighth incomplete transmission wheel 5421. Continue to step on the second pedal 40 downward, and the second pedal 40 simultaneously drives the seventh transmission bar 5412 and the eighth transmission bar 5413 to move downward, the ninth transmission bar 5422 drives the eighth incomplete transmission wheel 5421 to rotate forward, and the tenth transmission bar 5423 does not work, thereby completing an alternating process of forward rotation of the wheel 20, and the continuous advancement of the wheel 20 is achieved by repeatedly stepping on the first pedal 30 and the second pedal 40.

[0117] The working process of the reverse rotation of the wheel 20 on the same side as the second pedal 40 is as follows:

[0118] When the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point, if the user steps on the first pedal 30, the second pedal 40 moves upward, and the second pedal 40 drives the ninth transmission bar 5422 and the tenth transmission bar 5423 to move upward. If the ninth transmission bar 5422 drives the eighth incomplete transmission wheel 5421 to rotate in the opposite direction, the tenth transmission bar 5423 does not work; if the ninth transmission bar 5422 is engaged with the eighth incomplete transmission wheel 5421 and the tenth transmission bar 5423 is disengaged from the eighth incomplete transmission wheel 5421, the ninth transmission bar 5422 drives the eighth incomplete transmission wheel 5421 to rotate in the opposite direction, and the tenth transmission bar 5423 does not work. When the second pedal 40 moves to the highest point and the first pedal 30 moves to the lowest point, at this time, the ninth transmission bar 5422 begins to disengage from the eighth incomplete transmission wheel 5421, and the tenth transmission bar 5423 begins to engage with the eighth incomplete transmission wheel 5421. The second pedal 40 continues to be stepped on downward. At this time, the tenth transmission bar 5423 drives the eighth incomplete transmission wheel 5421 to rotate in the opposite direction, and the ninth transmission bar 5422 does not work, thereby completing an alternating process of reverse rotation of the wheel 20. By repeatedly stepping on the first pedal 30 and the second pedal 40, the continuous retreat of the wheel 20 is achieved.

[0119] When it is necessary to convert two wheels 20 that are rotating forward or backward at the same time into rotation in place, the body can be twisted in the alternating position so that one of the wheels 20 rotates in the opposite direction, thereby realizing rotation in place. For example, when the two wheels 20 are rotating forward at the same time, and the first pedal 30 is at the highest point and the second pedal 40 is at the lowest point, when the seventh incomplete transmission wheel 5411 is about to disengage from the eighth transmission bar 5413 and mesh with the seventh transmission bar 5412, the body is twisted so that the seventh incomplete transmission wheel 5411 rotates backward and meshes with the eighth transmission bar 5413, and when the first pedal 30 is stepped down, the eighth transmission bar 5413 drives the seventh incomplete transmission wheel 5411 to rotate backward; and the eighth incomplete transmission wheel 5421 continues to rotate forward under the twisting action, thereby realizing the conversion of the two wheels 20 that are rotating forward at the same time into rotation in place.

[0120] When it is necessary to convert the rotation in situ into two simultaneous forward rotations or simultaneous reverse rotations, the brake device 90 can be used to separate the seventh incomplete transmission wheel 5411 from the wheel 20 and keep the original inertial rotation without being affected by the twisting of the vehicle body 10, while the eighth incomplete transmission wheel 5421 rotates in the opposite direction to the original direction due to the twisting of the vehicle body 10, so that the rotation directions of the two wheels 20 are the same. For example, when the seventh incomplete transmission wheel 5411 rotates forward and the eighth incomplete transmission wheel 5421 rotates reversely, the brake device 90 can be used to separate the seventh incomplete transmission wheel 5411 from the wheel 20 and the seventh incomplete transmission wheel 5411 continues to rotate forward. When the vehicle body 10 is twisted at the alternating position, the eighth incomplete transmission wheel 5421 changes from reverse rotation to forward rotation. After releasing the brake device 90, the seventh incomplete transmission wheel 5411 and the eighth incomplete transmission wheel 5421 rotate forward at the same time.

[0121] 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 in the protection scope of the present invention.
