Abstract

A kart having a pedal speed controller and other components and arrangements thereof are disclosed. The kart can be provided with a controller for controlling speed; the pedal speed controller comprising a pedestal and a pedal, one end of the pedal is articulated with the pedestal and keeps a certain angle with the pedestal. The pedal speed controller also comprises a sensor connected with the controller, and the sensor can obtain displacement signal along the tread direction of the pedal. The pedal speed controller has the advantages of realizing pedal control of acceleration or deceleration for drivers, avoiding interference with manual adjustment of kart direction, preventing from mutual influence between speed regulation and steering, improving the speed control performance of the kart, and improving the driving experience.

First claim

What is claimed is:

1. A retention device for a kart battery, comprising:
a baseplate comprising a hook hole and an insertion hole;
a bracket comprising a transverse section that can apply a force to a surface of the battery, the bracket further comprising a lateral section that is coupled to the baseplate, wherein the transverse section comprises a socket; and
a locking hook and a nut, the locking hook comprising:
a first upwardly extending portion;
a second upwardly extending portion spaced apart from the first upwardly extending portion;
an intermediate portion that connects the first upwardly extending portion and the second upwardly extending portion; and
an end that is configured to be inserted into the socket of the bracket and fixed to the transverse section by the nut,

wherein the insertion hole is configured to receive a part of the locking hook therethrough and to enable the locking hook to be translated, relative to the baseplate, generally toward the hook hole;
wherein the hook hole is configured to receive the second upwardly extending portion of the locking hook after the locking hook has been inserted into the insertion hole and translated generally toward the hook hole; and
wherein the intermediate portion of the locking hook is configured to engage the baseplate between the insertion hole and the hook hole.

2. A kart, comprising:
a frame;
a seat supported by the frame;
a battery configured to power the kart;
the retention device of claim 1 ;
a front fork rotatably supported by the frame;
a front wheel rotatably supported by the front fork;
a motor operably coupled to the front wheel so that it can drive the front wheel; and
a controller operably coupled to the motor and configured to control a speed of the kart, the controller comprising:
a pedestal;
a pedal, wherein one end of the pedal is articulated with respect to the pedestal and the pedal maintains a certain angle with respect to the pedestal; and
a sensor connected to the controller, the sensor configured to determine a displacement signal of the pedal;

wherein the controller controls the speed of the kart based on the displacement signal detected by the sensor, and
wherein the baseplate or frame supports an anti-sway pillar extending below the baseplate or frame, the one anti-way pillar configured to contact a driving surface during a turning action of the kart and configured to inhibit the kart from tipping laterally.

3. The kart of claim 2 , wherein the battery is supported by the baseplate adjacent the front wheel and forward of the seat, and the controller is supported by the frame facing a rider on the kart.

4. The kart of claim 3 , wherein the front fork is arranged along a longitudinal axis of the frame, and the battery is supported by the baseplate and positioned on the longitudinal axis of the frame.

5. The kart of claim 4 , further comprising a shell configured to cover a top portion of the frame and enclose at least a portion of the battery, the controller, and the front fork.

6. The kart of claim 3 , further comprising a positioning structure configured to attach the battery to the baseplate, the positioning structure comprising a lock piece, a lock hook and a nut, wherein the lock piece comprises a transverse segment configured to attach to an upper surface of the battery, a lateral segment positioned at a lateral side of the battery, and a transverse permanent seat attached to the baseplate, the transverse segment including a plughole such that one end of a lock hook can be inserted into the plughole and fixed to the transverse segment of the lock piece by the nut.

7. The kart of claim 6 , wherein the baseplate further comprises an installation slot and the battery is locked by the lock piece inside the installation slot.

8. The retention device of claim 1 , further comprising a bolt such that the bracket is fixed to the baseplate by the bolt passing through the lateral section of the bracket.

9. The retention device of claim 8 , wherein the nut is a wing nut.

10. The retention device of claim 1 , wherein the baseplate forms at least a portion of a ridable kart.

11. The retention device of claim 1 , wherein the baseplate forms a kart baseplate of a ridable kart.

12. The retention device of claim 1 , wherein the baseplate further comprises an installation slot such that the bracket is configured to retain the battery in the installation slot.

13. A kart, comprising:
a frame;
a seat supported by the frame;
a battery configured to power the kart; and
a retention device for the battery, the retention device comprising:
a baseplate comprising a hook hole and an insertion hole;
a bracket comprising a transverse section that can apply a force to a surface of the battery, the bracket further comprising a lateral section that is coupled to the baseplate, wherein the transverse section comprises a socket; and
a locking hook and a nut, the locking hook comprising:
a first upwardly extending portion;
a second upwardly extending portion spaced apart from the first upwardly extending portion;
an intermediate portion that connects the first upwardly extending portion and the second upwardly extending portion; and
an end that is configured to be inserted into the socket of the bracket and fixed to the transverse section by the nut;

wherein the insertion hole is configured to receive a part of the locking hook therethrough and to enable the locking hook to be translated, relative to the baseplate, generally toward the hook hole;
wherein the hook hole is configured to receive the second upwardly extending portion of the locking hook after the locking hook has been inserted into the insertion hole and translated generally toward the hook hole; and
wherein the intermediate portion of the locking hook is configured to engage the baseplate between the insertion hole and the hook hole.

14. The kart of claim 13 , wherein the baseplate is supported by the frame.

15. The kart of claim 13 , further comprising a front fork rotatably supported by the frame and a front wheel rotatably supported by the front fork.

16. The kart of claim 15 , further comprising a motor operably coupled to the front wheel so that it can drive the front wheel.

17. The kart of claim 16 , further comprising a controller operably coupled to the motor and configured to control a speed of the kart.

18. The kart of claim 17 , wherein the controller comprises:
a pedestal;
a pedal, wherein one end of the pedal is articulated with respect to the pedestal and the pedal maintains a certain angle with respect to the pedestal; and
a sensor connected to the controller, the sensor configured to determine a displacement signal of the pedal.

19. The kart of claim 18 , wherein the controller controls the speed of the kart based on the displacement signal detected by the sensor.

20. The kart of claim 13 , wherein the baseplate or frame supports an anti-sway pillar extending below the baseplate or frame, the one anti-way pillar configured to contact a driving surface during a turning action of the kart and configured to inhibit the kart from tipping laterally.
