Exoskeleton wheelchair system
An exoskeleton wheelchair system includes a base, one or more wheels coupled to the base, a body support connected to the base. The body support includes a back support, and one or more leg supports pivotally coupled to the back support. The exoskeleton wheelchair system also includes an actuator linked with the one or more leg supports and configured to rotate the one or more leg supports, a processor, a memory module, and machine readable instructions that, when executed by the processor, cause the processor to rotate the one or more leg supports with the actuator. The one or more leg supports pivot about a first axis when the back support is in a standing position mode, and the first axis is maintained at a fixed position when the one or more leg supports pivot about the first axis while the back support is in the standing position mode.
1. An exoskeleton wheelchair device, comprising:
a base;
one or more wheels coupled to the base; and
a body support connected to the base, the body support comprising:
a back support; and
one or more leg supports pivotally coupled to the back support; and
an actuator linked with the one or more leg supports via one or more linkages and configured to rotate the one or more leg supports,
wherein the one or more leg supports are configured to pivot about a first axis when the back support is in a standing position mode,
wherein the first axis is maintained at a fixed position relative to a location of the base while the one or more leg supports pivot about the first axis and the back support is in the standing position mode, and
wherein the one or more linkages are pivotally coupled to a contour of the actuator.
2. The exoskeleton wheelchair device of claim 1 , wherein the actuator has a circular shape.
3. The exoskeleton wheelchair device of claim 2 , wherein one end of each of the one or more linkages makes a circular movement in response to a rotation of the actuator.
4. The exoskeleton wheelchair device of claim 1 , wherein the body support further comprises one or more straps configured to fix a user in the exoskeleton wheelchair device.
5. An exoskeleton wheelchair system, comprising:
a base;
one or more wheels coupled to the base;
a body support connected to the base, the body support comprising:
a back support; and
one or more leg supports pivotally coupled to the back support;
an actuator linked with the one or more leg supports via one or more linkages and configured to rotate the one or more leg supports;
a processor;
a memory module; and
machine readable instructions stored in the memory module that, when executed by the processor, cause the processor to rotate the one or more leg supports with the actuator,
wherein the one or more leg supports are configured to pivot about a first axis when the back support is in a standing position mode,
wherein the first axis is maintained at a fixed position relative to a location of the base while the one or more leg supports pivot about the first axis and the back support is in the standing position mode, and
wherein the actuator is mechanically coupled to the one or more wheels, and is configured to rotate in association with the one or more wheels.
6. The exoskeleton wheelchair system of claim 5 , wherein the back support is configured to transition between a wheelchair position mode and the standing position mode.
7. The exoskeleton wheelchair system of claim 6 , wherein the back support in the standing position mode is positioned at a higher position in terms of a vertical direction than a position of the back support in the wheelchair position mode.
8. The exoskeleton wheelchair system of claim 6 , wherein when the back support is in the standing position mode, the one or more leg supports pivot clockwise or counter-clockwise about the first axis.
9. The exoskeleton wheelchair system of claim 5 , wherein the one or more linkages are configured to push or pull the one or more leg supports to rotate the one or more leg supports about the first axis in response to a rotation of the actuator.
10. The exoskeleton wheelchair system of claim 5 , wherein the one or more linkages are pivotally coupled to a contour of the actuator.
11. The exoskeleton wheelchair system of claim 5 , wherein the actuator includes an electric motor.
12. The exoskeleton wheelchair system of claim 5 , further comprising
one or more armrests linked with the actuator via one or more arm linkages,
wherein the one or more armrests are configured to rotate about a fixed point in response to a rotation of the actuator.
