Abstract

The present invention discloses an improved self-running slide plate whose car body can be contracted. It is characterized by that a rear axle is fixed in the inner side of two retractable slipways, a rear plate is pivoted on the middle portion of said rear axle, two rear wheels are respectively placed on two ends of said rear axle, left and right two sides of said rear plate are respectively extended downwards, a brake is placed over the rear wheel hub. Said structure is simple, and its cost is low.

Description

Technical field: [0001] The invention relates to a wheeled vehicle driven by a rider, in particular to a skateboard, in particular to a self-propelled skateboard with a telescopic transmission mechanism, which is suitable for dryland skating. Background technique: [0002] Existing skateboards are formed by setting four pulleys under a base plate, and the user must drive with a pedal. The inventor has improved the prior art, and successively filed four patent applications with the State Intellectual Property Office, the publication numbers being respectively: CN1600396, CN1600632, CN1736524 and CN1749099. The common technical feature of the four patent applications is that the board surface is divided into front and rear two sections and fixed on a slideway, a return tension spring is arranged under the front and rear two board surfaces, and a one-way overrunning clutch is respectively arranged in the two rear wheels. . Therefore it can be seen that the one-way overrunning...
