Abstract

A control panel, a self-propelled switch apparatus, and a power device (13). The control panel comprises a pushing rod (1) connected to a machine body and a panel assembly (2) reciprocatingly sliding on the pushing rod. The control panel further comprises locking assembly (41, 42) connected to the panel assembly. The locking assembly (41, 42) are adapted to lock the panel assembly on the pushing rod and unlock the control panel and the pushing rod. The control panel further comprises a self-propelled switch (134), and when the self-propelled switch (134) is triggered, a device in which the control panel is disposed can be switched from a manual-power driving mode to a self-propelled driving mode. By means of the solution, a garden tool can walk in a self-propelled manner, and can also be pushed to walk.

First claim

I claim:

1. A control panel, comprising a pushing rod connected to a machine body;
a panel assembly reciprocatingly sliding on said pushing rod;
a locking assembly connected to said panel assembly, said locking assembly being adapted to lock said panel assembly on said pushing rod and unlock said panel assembly from said pushing rod;
a sensor configured to detect relative positions between said pushing rod and said panel assembly and to adjust a rotating speed of a motor driving said machine body; and
a self-propelled switch, wherein said self-propelled switch is configured to be triggered causing said machine body to be switched from a manual-power driving mode to a self-propelled driving mode;
wherein said locking assembly comprises a locking knob connected to said panel assembly, and at least one locking shaft connected to said locking knob and movable relative to said panel assembly to be latched with said pushing rod, wherein said locking rod is locked and unlocked with said pushing rod by entering and exiting said pushing rod, and said panel assembly slides along said pushing rod when said locking rod is unlocked;
wherein said panel assembly comprises a first switch unit connected with said locking knob, wherein said first switch unit is adapted to control said locking shaft to lock or unlock said panel assembly through said locking knob;
wherein said first switch unit comprises a self-propelled key connected with said locking knob, said locking knob is driven to rotate by rotating said self-propelled key about an axis of rotation extending transverse to said panel assembly; and
wherein said first switch unit further comprises a self-propelled key knob assembled on said self-propelled key, wherein said self-propelled key is driven to move upwardly and downwardly transverse to said panel assembly by said self-propelled key knob in a direction parallel to said axis of rotation of said self-propelled key.

2. The control panel as claimed in claim 1 , wherein said first switch unit further comprises a positioning assembly connected with said self-propelled key, wherein said positioning assembly is adapted to fix said self-propelled key.

3. The control panel as claimed in claim 1 , wherein when said locking knob rotates to bring said locking shaft to unlock said panel assembly, said locking knob simultaneously touches and triggers said self-propelled switch.

4. The control panel as claimed in claim 1 , further comprising a starting switch arranged on said panel assembly, said panel assembly comprises a starting unit disposed on said panel assembly, said starting unit comprises a starting key disposed on said panel assembly and being moveable upwardly and downwardly; wherein when said starting key moves to a bottom of said panel assembly, a bottom of said starting key will touch and start said starting switch under a push of a bottom of a pulling rod, and said starting switch will be closed when said bottom of said starting key disconnects from said starting switch.

5. The control panel as claimed in claim 4 , wherein said pulling rod comprises a compression block adapted to push said starting key to touch said starting switch as said pulling rod rotates, wherein a distance between said starting switch and said compression block is larger than a translation distance of said compression block caused by the rotation thereof.

6. The control panel as claimed in claim 1 , wherein said control panel comprises a starting switch and a starting unit, said starting unit comprising a button unit, a connecting assembly, and an operating assembly;
wherein said button unit moves downwardly to press said connecting assembly connecting with said operating assembly and said connecting assembly is driven to move and press said starting switch by moving said operating assembly, in such a manner that said starting switch is triggered.

7. The control panel as claimed in claim 6 , wherein said operating assembly comprises:
a pulling rod movably connected to said panel assembly and a pulling plate driven by said pulling rod;
said button unit comprises a pressing head configured to receive a pressing operation;
said connecting assembly comprises a sliding plate moveably connected with said panel assembly and a hanging plate movably connected with said sliding plate, wherein said pressing head is arranged on said upper part of said hanging plate, one end of said hanging plate is located on said upper part of said pulling plate, said pressing head is pressed down to engage said hanging plate and said pulling plate, and said hanging plate is driven to move by moving said pulling plate driven by said pulling rod; and
said sliding plate is driven to move along said panel assembly to trigger said starting switch through said hanging plate.

8. The control panel as claimed in claim 7 , wherein said pressing head includes an upper end, and further comprising a pressing head button arranged and connected at said upper end of said pressing head, and said pressing head is driven to move downward by pressing said pressing head button.
