It is suitable for detection and search operations in mountainous areas, especially for special areas such as earthquake-stricken areas and radiation areas.

Description

A throwing-type miniature robot throwing cabin opening mechanism

technical field

The invention belongs to the field of robot technology and aerospace. In particular, it relates to a cabin opening mechanism of a throwing two-wheeled robot throwing cabin. Designed for the application field of micro-robots, it is suitable for detection and search operations in mountainous areas, especially for special areas such as earthquake-stricken areas and radiation areas.

Background technique

The application background is in special scenarios such as detection and search in mountainous areas, earthquake relief, and nuclear leakage. Due to the unknown environment in the area, people cannot directly participate in the area operations or cannot guarantee the safety of the staff. In similar scenarios, it is required to be able to carry out pre-detection work in the area. The agency is designed for micro-robots, which can accurately place micro-robots in a specific area over a predetermined location.

Contents of the invention

The present invention provides a throwing two-wheel robot throwing cabin opening mechanism, and provides a simple and easy-to-use implementation scheme for the existing throwing methods. The invention has low cost and convenient installation and maintenance. The present invention is realized as described below.

A hatch opening mechanism includes a motor, a cam mechanism, a hatch hook, a hatch, and a micro switch. It is characterized by:

The motor is a DC motor driven by an external power supply and a PLC control box.

Described cam mechanism is driven cam by motor, and cam is positioned at cam groove, and cam groove drives hatch door hook to do lever motion around the hatch hook rotating shaft during work.

The hatch door is disengaged from the hatch door hook after the hatch door hook moves in place, and moves around the hatch door shaft under the action of the spring, thereby realizing the opening action.

The microswitch is used to disconnect the motor power supply when the hatch hook is in place.

According to the above, the cam groove is a rectangular groove, which is used to ensure the danger of opening the cabin door under malfunction.

According to the above, the spring is used to pull the hatch door back to the cabin body after the cabin is opened, so as to avoid possible problems such as preventing the robot from getting out of the cabin and hindering the flight safety of the aircraft.

According to the above, the microswitch acts when the cabin door is fully closed to ensure the safety of the cabin door in flight.

According to the above, the present invention is designed based on functions and actual use. The components such as the motor, hatch door, and hatch hook are all fixed on the cabin body by buckles, and the structure is simple and easy to install.

Detailed ways

Fig. 1 is the installation diagram of the present invention. Wherein the motor 11 and the micro switch 8 are connected to an external power supply and a PLC control box. When working, the PLC gives a signal to turn on the power supply to drive the motor to rotate.

Cam 10 is fixed on the motor 11 shaft by set screw 14, and when motor rotates, cam 10 rotates thereby driving cam groove 9 to drive hatch door hook 6 to rotate around hatch hook rotating shaft 7, and hatch door 5 is on spring when cam 10 rotates 180 °. 1 under the action of flipping around the door shaft 2, thereby realizing the process of opening the cabin.

When the hatch door needs to be closed for throwing again, the motor power supply is switched on manually, and when the hatch door hook 6 catches the hatch door 5, the micro switch 8 moves, so that the power supply is cut off and thus reaches the process of accurately closing the hatch door.
