Abstract

A longitudinal two-wheel somatosensory car, comprising a car frame, and a front wheel and a rear wheel that are provided at the front and rear ends of the car frame. The rear wheel is connected to a drive motor which is used for driving the rear wheel. The two-wheel car further comprises a somatosensory platform. The somatosensory platform is built-in with an attitude sensor. The somatosensory platform in a mechanical transmission connection with the motor stator shaft of the drive motor. The traditional balanced structure, in which the wheels are provided on the left and right sides of a balanced car, is changed to a structure in which the moving wheels are provided at the front and the rear ends.

First claim

What is claimed is:

1. A longitudinal two-wheel somatosensory car, comprising a car frame, and a front wheel and a rear wheel that are provided on front and rear ends of the car frame, wherein the rear wheel is connected to a drive motor used for driving the rear wheel to rotate, the two-wheel car further comprises a somatosensory platform, the somatosensory platform is built-in with an attitude sensor, and the somatosensory platform is in a mechanical transmission connection to a motor stator shaft of the drive motor.

2. The longitudinal two-wheel somatosensory car according to claim 1 , wherein the drive motor is an external rotor motor fixedly connected to the car frame and including an external rotor and an internal stator that are coaxial, an outer end of the external rotor is fixedly connected to a driving wheel that coaxially rotates with the external rotor, the driving wheel is in a transmission connection to a driven wheel that is fixedly disposed on the rear wheel and that rotates coaxially with the rear wheel, and two ends of a motor stator shaft of the internal stator respectively extend outward to be connected to the somatosensory platform.

3. The longitudinal two-wheel somatosensory car according to claim 1 , wherein the drive motor is an external rotor type hub motor, fixedly mounted in a hub of the rear wheel, a motor stator shaft of the hub motor is in a transmission connection to a driven wheel that is fixedly disposed on the somatosensory platform and that rotates coaxially with the somatosensory platform.

4. The longitudinal two-wheel somatosensory car according to claim 1 , wherein the somatosensory platform is a sitting-type somatosensory platform or a standing-type somatosensory platform.

5. The longitudinal two-wheel somatosensory car according to claim 1 , wherein the two-wheel car further comprises a steering handle connected to the front wheel.

6. The longitudinal two-wheel somatosensory car according to claim 5 , wherein the two-wheel car is in a modular structural design, and respectively comprises a front drive module, a rear drive module, and a somatosensory platform module that are independent from each other and that are able to be assembled and connected with each other; the front drive module comprises a front drive skeleton, and the steering handle and the front wheel; the steering handle passes through a mounting hole of a front section of the front drive skeleton to be connected to the front wheel disposed on a bottom end of the front drive skeleton; the rear drive module comprises a rear drive skeleton, the drive motor and the rear wheel; the rear wheel and the rear drive skeleton are fixedly mounted and connected; the somatosensory platform module comprises the somatosensory platform; the front drive skeleton and the rear drive skeleton are assembled and connected to each other to form the car frame; and the somatosensory platform module is fixedly mounted and connected at a coaxial connection location of the front drive skeleton and the rear drive skeleton.

7. The longitudinal two-wheel somatosensory car according to claim 6 , wherein the two-wheel car further comprises a shock absorption module; the shock absorption module is fixedly mounted and disposed between the front drive skeleton and the rear drive skeleton, one end of the shock absorption module is connected to the front drive skeleton, and the other end is connected to the rear drive skeleton.

8. The longitudinal two-wheel somatosensory car according to claim 7 , wherein coaxial first openings are disposed on two sides of an upper end of the front drive skeleton, and coaxial second openings are disposed on an upper end of the rear drive skeleton, and pivot connection members corresponding to the first openings and the second openings are respectively correspondingly disposed on two ends of the shock absorption module.

9. The longitudinal two-wheel somatosensory car according to claim 6 , wherein the front drive skeleton comprises a skeleton body and a front drive upper cover in a fitting connection to the skeleton body; a battery cavity is disposed in the skeleton body, and a battery pack is built in the battery cavity.

10. The longitudinal two-wheel somatosensory car according to claim 2 , wherein the somatosensory platform is a sitting-type somatosensory platform or a standing-type somatosensory platform.

11. The longitudinal two-wheel somatosensory car according to claim 3 , wherein the somatosensory platform is a sitting-type somatosensory platform or a standing-type somatosensory platform.
