Correspondingly, the right side of the top wall of transverse connecting member 30 is provided with two second support members 32. Two second support members 32 are all provided with the second recesses matching the second cylinders. Right pedal 20 is connected to second support member 32 in a rotatable manner.

[0043] Preferably, first resilient members 12 and second resilient members 22 are also included. One end of first resilient member 12 is connected to the bottom of left pedal 10, and the other end correspondingly is connected to the left side of the top wall of transverse connecting member 30. One end of second resilient member 22 is connected to the bottom of right pedal 20, and the other end thereof is correspondingly connected to the right side of the top wall of transverse connecting member 30.

Left pedal 10 and right pedal 20 is rotatably connected to transverse connecting member 30 respectively. Left pedal 10 and right pedal 20 are independent from each other. During the use of the balancing vehicle, the weight applied to the pedal by the human body is conveyed to transverse connecting member 30, such that transverse connecting member 30 bears the weight of the human body, and thus the force distributes evenly. This avoids the defect of the prior art in which in the balancing vehicle, the left and right pedals are connected through a middle shaft, and the middle shaft bears the weight of the human body, and therefore the middle shaft is likely to wear and even crack. balancing vehicle made by this pedal connection mechanism is reliable, safe, and durable. Moreover, this pedal connection mechanism not only can be used in a double-wheeled balancing vehicle, but also can be used in a three-wheeled balancing vehicle, a four-wheeled balancing vehicle, or other suitable types of vehicles. It has a wide range of applications, a high practical utility, and a great commercial prospect.

[0046] The present invention further provides an electric balancing vehicle using this pedal connection mechanism, which includes a housing, a pedal connection mechanism, wheels, motors, main boards, and a power supply. The interior of the housing is provided with an accommodating cavity, and the top surface thereof is provided with the first notch and the second notch that are bilaterally symmetrical with each other. The first notch matches left pedal 10. The second notch matches right pedal 20. The pedal connection mechanism is provided within the accommodating cavity. Among others, left pedal 10 is provided inside the first notch, and right pedal 20 is provided inside the second notch. The wheels include a left wheel and a right wheel. They are provided on the left and right sides of the housing respectively. The motors include the first motor and the second motor. The first motor is provided within the left wheel, with its power output terminal being connected to the left wheel drive. After receiving the signal transmitted from the main board, the first motor controls the motion status of the left wheel. The second motor is provided within the right wheel, with its power output terminal being connected to the right wheel drive. After receiving the signal transmitted from the main board, the second motor controls the motion status of the right wheel. Main boards include a left main board and a right main board. The left main board is provided on the bottom of left pedal 10, and is provided in parallel with left pedal 10. Right main board 20 is provided on the bottom of right pedal 20, and is provided in parallel with right pedal 20. The left main board includes a first sensor, a first signal processor, and at least one first touch sensing switch. The first sensor senses the motion status of left pedal 10, with its signal output terminal being connected to the first signal processor. The signal output terminal of the first signal processor is connected to the first signal input terminal of the first motor. The signal output terminal of the first touch sensor is connected to the second signal input terminal of the second motor. The right main board includes a second sensor, a second signal processor, and at least one second touch sensing switch. The second sensor sensing the motion status of the right pedal, with its signal output terminal being connected to the signal input terminal of the second signal processor. The signal output terminal of the second signal processor is connected to the first signal input terminal of the second motor. The signal output terminal of the second touch sensor is connected to the second signal input terminal of the second motor. The power supply is provided within the accommodating cavity, providing energy for the electric balancing vehicle.

[0047] Hereinafter, the providing manners of the left main board and the right main board are further illustrated.

[0048] The first sensor includes the first gyroscope and the first acceleration sensor.

[0049] Preferably, the number of first touch sensing switches is two. The number of second touch sensing switches is two. Among others, one first touch sensing switch and one second touch sensing switch are spare switches. Providing spare switches is convenient and practical, because it avoids the defect of providing only one switch in which once the switch is broken, the balancing vehicle cannot start up.

[0050] Moreover, a power display is provided outside the top surface or the sidewall of the housing. A night light is provided outside the sidewall of the housing. the user can clearly know the power status of the balancing vehicle through the power display, and can recharge in time, so as to avoid the situation in which the vehicle is stopped due to the lack of power. Moreover, a night light is further provided on the housing. The night light can improve the safety when the user is using the electric balancing vehicle at night.

[0051] The working principle of the electric balancing vehicle provided by the present invention is as follows:

[0052] During the operation of the electric balancing vehicle, when the user's left foot steps on left pedal 10, touching the touch sensing switch on the left main board such that the touch sensing switch is turned on. When the user's right foot steps on right pedal 20, touching the touch sensing switch on right main board such that the touch sensing switch is turned on the user's left foot steps on left pedal 10, such that left pedal 10 inclines forwards or backwards, Meanwhile, the left main board which is parallel connected to the bottom of left pedal 10 inclines forwards or backwards along with left pedal 10. At this time, the first sensor on the left main board detects the motion status of left pedal 10 constantly, and transmits the signal to the first signal processor on left main board. The first signal processor feeds back to the first motor. The motion status of the left wheel is adjusted correspondingly according to the power output of the first motor. On the other hand, the user's right foot steps on right pedal 20, such that right pedal 20 inclines forwards or backwards. Meanwhile, the right main board which is parallel connected to the bottom of right pedal 20 inclines forwards or backwards along with right pedal 20. At this time, the first sensor on the right main board detects the motion status of right pedal 20, and transmits the signal to the second signal processor on the right main board. The second signal processor feeds back to the second motor. The motion status of the right wheel is adjusted correspondingly according to the power output of the second motor. When the user steps hard on left pedal 10 and right pedal 20 simultaneously to the forward, the left wheel and the right wheel keep rolling forwards, and the balancing vehicle moves forwards. When the user steps hard on left pedal 10 and right pedal 20 backwards simultaneously, the left wheel and the right wheel keep rolling backwards, and the balancing vehicle moves backwards. However, when the stepping motion of the user makes motion statuses of left pedal 10 and right pedal 20 inconsistent, the balancing vehicle will turn. Meanwhile, the first sensor and the second sensor will feed back the swing magnitude of the user's body, such that the first motor and the second motor obtain different power outputs, so as to adjust the velocity of the balancing vehicle.

[0053] For a person with ordinary skill in the art, other kinds of corresponding alternations and modifications can be made according to technical solutions and concepts described above. All of these alternations and modifications should belong to the scope of the claims of the present invention.
