Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1 and 2, the present embodiment provides a two-wheeled electric vehicle including a cross arm 1, wheels 2, a cockpit 3, and a balance weight. The balancing stand comprises a first ring body 4, a second ring body 5 and a third ring body 6, and the first ring body 4, the second ring body 5 and the third ring body 6 are all circular or oval. The shapes of the first ring 4, the second ring 5 and the third ring 6 are selected as appropriate according to the actual situation.

In the embodiment, for example, the shapes of the first ring body 4, the second ring body 5 and the third ring body 6 are circular, the left outer side surface and the right outer side surface of the first ring body 4 are respectively and correspondingly and rotatably connected with the two wheels 2 through the two cross arms 1, and the two cross arms 1 are overlapped with the left radial axis 9 and the right radial axis 9 of the first ring body 4. The concrete connection structures of the two cross arms 1 are the same, and the embodiment takes the cross arm 1 on the left as an example for explanation: the right end of the cross arm 1 is fixedly connected with the outer side face of the left side of the first ring body 4, the left end of the cross arm 1 is provided with a protruding driving shaft 8, and the driving shaft 8 is fixedly connected with the left wheel 2.

In the embodiment, the driving part adopts a motor 7, namely, the two cross arms 1 are provided with the motors 7 for driving the corresponding wheels 2. The motors 7 are all fixedly connected to the lower side surfaces of the corresponding cross arms 1. Two motors 7 are hidden at the lower side surface of the cross arm 1, so that the situation that the motor is arranged at the upper side surface of the cross arm 1 and is prominent, and the overall attractiveness is influenced is avoided.

And a transmission gear set is arranged in the cross arm 1, and an output shaft of the motor 7 is in transmission connection with the corresponding driving shaft 8 through the transmission gear set. The driving shaft 8 is rotatably mounted in the cross arm 1 through a bearing, and a transmission gear set is further arranged in the cross arm 1 and is a reduction gear set used for reducing the rotating speed of the motor 7 so as to obtain enough driving power. The two motors 7 respectively and independently work to independently drive the corresponding wheels 2. When the two motors 7 rotate synchronously, straight line running is realized, and steering is realized when the motors rotate asynchronously. The motor 7 is electrically connected with a control circuit of the cockpit 3 through a lead and is controlled by an operation interface of the cockpit 3.

The specific connection structure of the first ring body 4, the second ring body 5 and the third ring body 6 is as follows:

the second ring body 5 is rotatably installed on the inner side surface of the first ring body 4 through a first rotating shaft, the first rotating shaft is overlapped with the left and right radial axes 9 of the first ring body 4, and the third ring body 6 is rotatably installed on the inner side surface of the second ring body 5 through a second rotating shaft, and the second rotating shaft is overlapped with the front and rear radial axes 10 of the second ring body 5. Here, the right and left radial axes 9 refer to the dashed lines AB and the front and rear radial axes 10 refer to the dashed lines CD in fig. 1. The cockpit 3 is fixedly arranged at the lower part of the inner side surface of the third ring body 6, namely the cockpit 3 is fixedly connected with the inner side surface of the third ring body 6 positioned at the lower part.

The working principle of the device is as follows:

the driver rides in the cab 3 to drive, and the driver controls the start, stop, and speed of the vehicle through the operation interface. Since the second ring 5 can rotate about the first axis of rotation and the third ring 6 rotates about the second axis of rotation, the principle of balance of a three-axis gyroscope is used. Whether the vehicle is stopped or driven or the vehicle is braked and accelerated in the driving process, the cab 3 can be always vertical when the vehicle is driven on an uneven road or a road with a slope, namely, a driver is always upright, the possibility of side turning is greatly reduced, and the driving safety level is improved. The brake mechanism in the device can realize braking by controlling the motor 7 to stop rotating, and can also realize braking by arranging a brake component on the cross arm 1.
