Abstract
A body of a vehicle can include a front structure including a front wheel of the vehicle; a rear structure including a rear wheel of the vehicle; a rotation shaft connecting the front structure and the rear structure and allowing the front structure and the rear structure to rotate relative to each other; and an elastic system providing a return force in the opposite direction of the relative rotation in response that the front structure and the rear structure rotate relative to each other is disclosed.
Claims20
A vehicle body of a vehicle, comprising:
- a front structure of the vehicle body including a front wheel of the vehicle;
- a rear structure of the vehicle body including a rear wheel of the vehicle;
- a rotation shaft extending in a longitudinal direction of the vehicle, connecting the front structure and the rear structure, and configured to allow the front structure and the rear structure to rotate relative to each other;
- and
- an elastic system configured to provide a return force in an opposite direction of relative rotation in response to the front structure and the rear structure rotating relative to each other;
- wherein the front structure and the rear structure are able to rotate relative to each other about a center of the rotation shaft;
- wherein the elastic system includes an elastic body configured to store an elastic force upon compression;
- and
- wherein the elastic body is connected to the front structure or the rear structure depending on a relative rotation direction of the front structure and the rear structure.

A vehicle body of a vehicle, comprising:
- a front structure of the vehicle body including a front wheel of the vehicle;
- a rear structure of the vehicle body including a rear wheel of the vehicle;
- a rotation shaft connecting the front structure and the rear structure and configured to allow the front structure and the rear structure to rotate relative to each other;
- an elastic system configured to provide a return force in an opposite direction of relative rotation in response to the front structure and the rear structure rotating relative to each other;
- a front frame provided in the front structure;
- a rear frame provided in the rear structure, wherein the rotation shaft has a first end fixed to either one of the front frame or the rear frame, and a second end rotatably coupled to another of the rear frame or the front frame, respectively, wherein when the first end of the rotation shaft is fixed to the front frame then the second end of the rotation shaft is rotatably coupled to the rear frame, and wherein when the first end of the rotation shaft is fixed to the rear frame then the second end of the rotation shaft is rotatably coupled to the front frame;
- a stopping protrusion provided on an outer circumferential surface of the second end of the rotation shaft;
- a limiting protrusion base provided on the front frame or rear frame;
- and
- a pair of limiting protrusions provided to face each other at each of limiting-protrusion-base ends of the limiting protrusion base, and wherein the stopping protrusion and the pair of limiting protrusions are configured such that the stopping protrusion can move between the pair of limiting protrusions so that a relative rotation angle of the front frame and the rear frame is limited.

A vehicle body of a vehicle, comprising:
- a front structure of the vehicle body including a front wheel of the vehicle, a front body, and a front frame, wherein the front body and the front frame may slide up and down relative to each other by a front fixing portion configured to fix a first relative position to which the front body and the front frame slide;
- a rear structure of the vehicle body including a rear wheel of the vehicle, a rear body and a rear frame, wherein the rear body and the rear frame may slide up and down relative to each other by a rear fixing portion configured to fix a second relative position to which the rear body and the rear frame slide;
- a rotation shaft connecting the front structure and the rear structure and configured to allow the front structure and the rear structure to rotate relative to each other;
- and
- an elastic system configured to provide a return force in an opposite direction of relative rotation in response to the front structure and the rear structure rotating relative to each other.
