Braking device for a personal mobility vehicle
A personal mobility vehicle, such as a scooter, includes at least one battery and motor for powering at least one driven wheel. The vehicle also includes a braking assembly configured to isolate the motor from the at least one driven wheel such that power is terminated from the motor to the at least one wheel in response to a user engaging a braking assembly of the vehicle. The vehicle can include a switch or position sensor that interacts with the braking assembly to initiate the isolation of the motor from the at least one driven wheel and the switch or position sensor preferably is inaccessible to the foot of the user.
1. A personal mobility vehicle comprising:
a body having a deck and an opening extending through the deck, the deck being configured to support a user, the deck defining a first height;
at least one wheel connected with the body and rotatable around an axis;
a braking assembly supported by the body; the braking assembly comprising:
an actuator portion that extends through the opening, the actuator portion having a second height accessible to the foot of a user through the opening;
a braking surface connected with the actuator portion and configured to apply frictional braking force when in contact with the at least one wheel;
a motor connected with the body and arranged to transfer rotational force to the at least one wheel;
a switch connected with the body and positioned below the deck;
wherein the braking assembly has an engaged position in which the braking surface is in contact with the at least one wheel;
wherein the braking assembly has a second position in which the braking surface does not contact the at least one wheel, the braking assembly being movable to the engaged position in response to the user acting upon the actuator portion, wherein the second height is greater than the first height such that the second height remains greater than the first height after moving the braking assembly to the engaged position and a top surface of the actuator portion does not move below the first height;
wherein the switch is configured to be actuated when the braking assembly is moved from the second position to the engaged position, and actuating the switch stops or impedes the transfer of force from the motor to the at least one wheel.
2. The personal mobility vehicle of claim 1 , wherein the braking assembly is configured to be rotatably supported by the body.
3. The personal mobility vehicle of claim 1 , wherein the braking assembly is biased away from the engaged position.
4. The personal mobility vehicle of claim 1 , wherein the braking surface is configured to apply a frictional braking force upon the outer circumference of the at least one wheel.
5. The personal mobility vehicle of claim 1 , wherein the actuator portion is proximate the foot of the user and the deck and the actuator portion are generally oval in shape from a top view with a major axis of the oval extending in a lengthwise direction of the deck.
6. The personal mobility vehicle of claim 1 , wherein the deck defines a surface on which the user can stand and covers at least a portion of the at least one wheel, and the actuator portion extends above the deck.
7. The personal mobility vehicle of claim 1 , wherein the braking surface is part of a braking member which is a separate piece supported by the braking assembly.
8. The personal mobility vehicle of claim 1 further comprising a handlebar assembly available to the user, the handlebar assembly comprising a throttle configured to allow power transfer from the motor to the at least one wheel.
9. The personal mobility vehicle of claim 8 , wherein the throttle is isolated from the motor when the braking assembly is moved to the engaged position.
10. The personal mobility vehicle of claim 1 , wherein the switch is positioned underneath the deck of the personal mobility vehicle.
11. The personal mobility vehicle of claim 10 , wherein the switch is positioned forward of the axis of the at least one wheel.
12. A braking assembly for a personal mobility vehicle, the personal mobility vehicle having a support member, a wheel, at least one battery and a motor configured to transfer power to the wheel, the braking assembly comprising:
a body comprising:
an attachment portion configured to be connected with the personal mobility vehicle;
an actuator portion that is accessible to a foot of a user, the actuator portion including a switch release member;
a braking member connected with the body and configured to apply frictional braking force when in contact with the wheel;
a switch configured to be connected with the body and underneath a portion of the personal mobility vehicle;
wherein the body is movable to an engaged position in which the braking member is in contact with a wheel in response to the user acting upon the actuator portion;
wherein, in response to the user acting upon the actuator portion, the switch release member engages at least a portion of the switch when the body is in a disengaged position and the switch release member pulls a portion of the switch to disengage the switch when the body is moved to the engaged position.
13. The braking assembly of claim 12 , wherein the body is biased away from the engaged position.
14. The braking assembly of claim 12 , wherein the braking member is configured to apply a frictional braking force upon an outer circumference of the wheel.
15. The braking assembly of claim 12 , wherein the actuator portion extends through a portion of the personal mobility vehicle.
16. The braking assembly of claim 12 , further comprising a switch contact portion configured to interact with the switch, the switch being configured to change status when the switch contact portion is moved relative to the switch.
17. A personal mobility vehicle configured to roll over a surface, the vehicle comprising:
a body having a deck configured to support a user, a rear portion of the deck being at a first height above the surface, the body further comprising an opening extending through the deck;
at least one wheel connected with the body and rotatable around an axis, the wheel configured to roll on the surface;
a braking assembly connected with the body, the braking assembly comprising an actuator portion that extends through the opening, the actuator portion having a second height above the surface, a top portion of the actuator portion being accessible to the foot of a user;
the braking assembly being movable to an engaged position in response to a generally downward force being applied to the actuator portion, the braking assembly being configured such that in the engaged position:
the braking assembly applies frictional braking force to the at least one wheel; and
the second height is greater than the first height.
18. The personal mobility vehicle of claim 17 , wherein, in the engaged position, the top surface of the actuator portion is higher than the first height.
