Vehicle Frame

Abstract

As shown in the "reference perspective view showing the state of use," this article is a vehicle frame that supports wheels in a vehicle that has a saddle for a human body to sit on, three wheels, a brake for braking the wheels, and a handle for steering the wheels. The wheels include front wheels and rear wheels attached to the vehicle frame. The front wheels include a left front wheel and a right front wheel, making up a pair of two wheels on the left and right. The rear wheels are connected to a motor attached to the vehicle frame. This motor rotates the rear wheels, which are drive wheels, around a rotation axis in response to an accelerator operation input by a vehicle user. This article is a lower unit that has wheels. As shown in the "reference exploded perspective view showing the article and the upper unit," the lower unit is detachably attached to an upper unit that has a saddle and a handle. The lower unit is connected to the upper unit and includes a lower plate that mechanically transmits steering operation of the handle and braking operation of the brake from the upper unit. Here, the upper unit includes an upper plate that is connected to the lower plate of the lower unit and mechanically transmits the steering operation of the handlebars and the braking operation of the brakes to the lower unit. The vehicle can mechanically transmit the operation of the upper unit to the lower unit by attaching the upper plate and the lower plate. Therefore, the vehicle can easily replace only the upper unit, and even if the upper unit is replaced, the mechanical operation can be transmitted from the new upper unit to the lower unit.
