Self-adaptive vehicle frame

Abstract

The invention discloses a self-adaptive vehicle frame comprising a vehicle body, a first supporting arm, a second supporting arm, a driving wheel, a first auxiliary wheel, a second auxiliary wheel anda swing rod. The middle portion of the first supporting arm is connected to one end of the vehicle body in a pivoted manner. The first auxiliary wheel is arranged at one end of the first supporting arm. One end of the swing rod is connected to the other end of the vehicle body in a pivoted manner. The other end of the swing rod is connected to the middle portion of the second supporting arm in apivoted manner. The second auxiliary wheel is arranged at one end of the second supporting arm. The other end of the first supporting arm is connected with the other end of the second supporting arm in a pivoted manner. The driving wheel is connected to the first supporting arm in a pivoted manner and located between the first auxiliary wheel and the second auxiliary wheel. By means of the self-adaptive vehicle frame, all wheels can be kept in effective contact with the ground on rough roads, and normal running is ensured.

Description

technical field [0001] The invention relates to a vehicle frame, in particular to a wheelchair frame capable of keeping each wheel in effective contact with the ground on uneven roads and ensuring normal driving. . Background technique [0002] The existing two-wheeled self-balancing vehicles generally have two large wheels, and in order to ensure the balance of the two-wheeled self-balancing vehicle, auxiliary small wheels are added on both sides of the large wheel in the front and rear directions. The large wheels are usually directly installed on the two-wheeled self-balancing vehicle The frame is driven by a motor fixed on the frame. The small wheel is usually pivotally connected to the support arm, and the support arm is pivotally connected to the frame, and the shock absorber is used for shock absorption, while the small wheel and the support arm provide auxiliary support for the frame to prevent the frame from losing balance. . Although the existing two-wheeled sel...

Problems solved by technology

Although the existing two-wheel balance car has good adaptability on smooth roads, it may not be able to move forward when driving on uneven roads.

This is because the front and rear small wheels are supported by independent support arms and shock absorbers. When the large wheels pass through low-lying ground and the front and rear small wheels are on a higher ground, the two small wheels may directly support the wheelchair wheel, and the big wheel will be erected, unable to contact the low-lying ground, and the whole frame is driven forward through the motor output power to the big wheel, therefore, the motor at this time The driving force cannot be converted into forward power, so that the two-wheeled balance frame cannot move forward
