Abstract

The present invention provides a movable vehicle. The movable vehicle comprises a carrying mechanism and a holding mechanism connected to the carrying mechanism, and the bottom of the carrying mechanism is provided with wheels, wherein the movable vehicle further comprises a starting mechanism arranged on the holding mechanism, the starting mechanism comprising a starting unit, a power supply unit, and a controller. The starting unit is configured to be switchable between an initial position and a start position. The controller is configured to be electrically connectable to the power supply unit, wherein when the starting unit is in the start position, the starting unit is coupled to the controller to activate the electrical connection between the controller and the power supply unit, and when the starting unit is in the initial position, the starting unit is decoupled from the controller. According to the above solution, a user can easily activate the electrical connection between the controller and the power supply unit simply by operating the starting unit on the holding mechanism, thereby allowing the controller to further perform various control operations.

First claim

The invention claimed is:

1. A movable vehicle, the movable vehicle comprising: a carrying mechanism and a holding mechanism connected to the carrying mechanism, and a bottom of the carrying mechanism is provided with wheels, wherein the movable vehicle further comprises a starting mechanism arranged on the holding mechanism, the starting mechanism comprising: a starting unit configured to be movable between an initial position and a start position, wherein the entire starting unit is irremovably arranged on the holding mechanism in both the initial position and the start position; a power supply unit; a controller configured to be electrically connectable to the power supply unit, wherein when the starting unit is in the start position, the starting unit is coupled to the controller to activate an electrical connection between the controller and the power supply unit, and when the starting unit is in the initial position, the starting unit is decoupled from the controller; the starting mechanism further comprising a locking portion, the locking portion having a lock position and an unlock position and being configured to, when in the lock position, lock the starting unit in the initial position.

2. The movable vehicle as claimed in claim 1 , wherein the starting unit is configured as a knob rotatably arranged on the holding mechanism, the knob being configured to be rotatable between the start position and the initial position.

3. The movable vehicle as claimed in claim 1 , wherein the locking portion is configured as a locking rod and that one of the locking rod and the starting unit is provided with a protrusion and the other one thereof is provided with a recess that fits the protrusion, the protrusion being removably coupled in the recess.

4. The movable vehicle as claimed in claim 3 , wherein the locking rod is pivotally connected to the holding mechanism around a pivot shaft and a pressing portion is arranged on the locking rod, the pressing portion being opposite the protrusion on both sides relative to the pivot shaft.

5. The movable vehicle as claimed in claim 1 , the movable vehicle further comprising an electric motor and a driving unit connected to the electric motor, wherein the electric motor drives a wheel axle of the wheels through the driving unit.

6. The movable vehicle as claimed in claim 5 , the movable vehicle further comprising a clutch mechanism arranged on the carrying mechanism, and the clutch mechanism is configured to cause the driving unit to be selectively coupled to or decoupled from the wheel axle of the wheels.

7. The movable vehicle as claimed in claim 1 , the movable vehicle further comprising a first housing portion and a second housing portion opposite the first housing portion, the first housing portion is arranged on a side of the holding mechanism near the carrying mechanism, the first housing portion and the second housing portion are butt-jointed at the holding mechanism, the first housing portion and the second housing portion form an accommodating space, and the controller, a part of the locking portion, and a first connecting member are arranged in the accommodating space.

8. The movable vehicle as claimed in claim 7 , wherein one of the first housing portion and the second housing portion is provided with a first through hole and a second through hole, a direction adjustment rod extending through the first through hole, the locking portion extending through the second through hole.

9. The movable vehicle as claimed in claim 1 , wherein the carrying mechanism comprises a first frame portion and a second frame portion, the first frame portion being connected to the second frame portion, the first frame portion being pivotable relative to the second frame portion between an initial position and a lifted position,
wherein the carrying mechanism further comprises a support device, wherein a first end of the support device is connected to the first frame portion and a second end thereof is connected to the second frame portion, and the support device is configured to support the first frame portion when the first frame portion is in the lifted position, thereby keeping the first frame portion in the lifted position.

10. The movable vehicle as claimed in claim 9 , wherein the holding mechanism is connected to one end of the second frame portion, the first frame portion is pivotally connected to the second frame portion around a first pivot shaft, and the first pivot shaft is connected to the other end of the second frame portion away from the holding mechanism.

11. The movable vehicle as claimed in claim 10 , wherein the second frame portion comprises a second distal bracket, the second distal bracket being arranged at one end of the second frame portion away from the holding mechanism, the first frame portion comprises a first distal bracket, the first distal bracket being arranged at one end of the first frame portion away from the holding mechanism, and the first distal bracket is further away from the holding mechanism than the second distal bracket.

12. The movable vehicle as claimed in claim 11 , wherein the first frame portion further comprises a first extension frame and a second extension frame arranged to be substantially parallel to the first extension frame, the first distal bracket is connected to the ends of the first extension frame and the second extension frame, the first frame portion further comprises an intermediate bracket connected between the first extension frame and the second extension frame, and the intermediate bracket is arranged to be substantially parallel to the first distal bracket.

13. The movable vehicle as claimed in claim 12 , wherein a first end of the support device is connected to the intermediate bracket and a second end thereof is connected to the second distal bracket.

14. The movable vehicle as claimed in claim 13 , wherein the support device comprises a mounting base, the mounting base being fixedly connected to the second distal bracket, a second pivot shaft being arranged on the mounting base.

15. The movable vehicle as claimed in claim 14 , wherein the support device further comprises a first support portion and a second support portion, the first support portion and the second support portion are separate components, the first support portion is connected to the intermediate bracket, the second support portion is connected to the second distal bracket, and the support device further comprises an elastic member configured to act simultaneously on the first support portion and the second support portion.

16. The movable vehicle as claimed in claim 15 , wherein the first support portion comprises a first peripheral portion and a first extension section connected to the first peripheral portion, the second support portion comprises a second peripheral portion and a second extension section connected to the second peripheral portion, the first extension section and the second extension section are arranged opposite each other, the elastic member is configured as a spring, and the spring is sleeved on the outside of at least one of the first extension section and the second extension section, wherein, when the first frame portion is in the initial position, the spring is in a compressed state and both ends thereof are respectively connected to the first peripheral portion and the second peripheral portion.
