Abstract
Various electric balance vehicles are described. In some embodiments, the vehicle has first and second housings with platforms to support a user's feet. The first and second housings can be rotatable relative to each other. The vehicle can have first and second wheel assemblies. A support member can extend within tapered portions of the first and second housings. In some embodiments, one of the first and second housings can rotate relative to the support member and the other of the housings can be rotationally fixed relative to the support member. The vehicle can balance and provide locomotion to the user. The vehicle can be light, compact, and/or have a low center of gravity.
Claims20
An electric balance vehicle, comprising:
- a first foot placement section comprising a first housing and a first wheel assembly, the first wheel assembly comprising a first wheel, a first motor positioned within the first wheel, and a first axle extending from the first wheel;
- a second foot placement section comprising a second housing and a second wheel assembly, the second wheel assembly comprising a second wheel, a second motor positioned within the second wheel, and a second axle extending from the second wheel;
- a connection member having a first end and a second end, wherein the first end is positioned within the first housing and the second end is positioned within the second housing;
- and
- wherein the first housing comprises a first gap between the first end of the connection member and the first wheel assembly;
- and
- wherein the second housing comprises a second gap between the second end of the connection member and the second wheel assembly.
An electric balance vehicle, comprising:
- a first housing and a second housing, each of the first and second housings configured to support a respective foot of a user, the second housing being rotatable relative to the first housing;
- a first wheel assembly comprising a first wheel, a first motor positioned within the first wheel, and a first axle extending from the first wheel;
- a second wheel assembly comprising a second wheel, a second motor positioned within the second wheel, and a second axle extending from the second wheel;
- a support member connecting the first and second housings;
- a first controller for controlling the first wheel assembly and a second controller for controlling the second wheel assembly;
- a battery for supplying power to the first and second controllers and the first and second motors;
- and
- a first sensor provided in the first housing and a second sensor provided in the second housing, the first sensor configured to sense rotation of the first housing and generate a first sensing signal and the second sensor configured to sense rotation of the second housing and generate a second sensing signal;
- wherein the battery and the first controller are disposed to a first lateral side of the support member, between the support member and the first axle, and the second controller is disposed to a second lateral side of the support member, between the support member and the second axle.
