[0026] This section is an embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.

[0027] An electromechanical brake control device includes a controller 1, a power supply 2, a micro switch 3, an electric control switch 4 and a power output mechanism 5; the controller 1 is connected to and controls the electric control switch 4, the power supply 2 is connected to the power output mechanism 5 through the electric control switch 4, and a micro switch 3 is also provided between the power supply 2 and the power output mechanism 5, and the micro switch 3 is controlled by a mechanical insurance starting device.

[0028] The micro switch 3 is a mechanical normally closed switch. When the mechanical linkage button of the micro switch 3 is pressed, the micro switch 3 is opened.

[0029] The mechanical safety starting device comprises a plug-in lock pin 6 , which contacts and presses the mechanical linkage button of the micro switch 3 when inserted, so that the micro switch 3 is disconnected.

[0030] The mechanical safety starting device also includes a lever brake mechanism 7. When the plug-in lock pin 6 is not inserted, the lever brake mechanism 7 is in a relaxed state, and both ends of the lever brake mechanism 7 are not in contact with other structures; after the plug-in lock pin 6 is inserted, the plug-in lock pin 6 contacts one end of the lever brake mechanism 7, so that the other end of the lever brake mechanism 7 engages with the power output mechanism 5, thereby locking the power output mechanism 5.

[0031] The controller 1 is also grounded via the plug-in switch 8 . The plug-in switch 8 is disconnected when the plug-in lock pin 6 is not inserted, and is connected after the plug-in lock pin 6 is inserted.

[0032] The plug-in lock pin 6 is made of a metal conductive material, and the plug-in switch 8 is turned on by mechanically overlapping the two joints of the plug-in switch 8 with the plug-in lock pin 6 to achieve the on state.

[0033] The controller 1 is provided with a high-level start signal by the plug-in switch 8; when the plug-in switch 8 is turned on, a low-level signal is provided to the controller 1, and the controller 1 does not start to output control instructions; when the plug-in switch 8 is disconnected, a high-level start signal is provided to the controller 1, and the controller 1 starts working, and outputs control instructions when the working conditions are met, controls the electronic control switch 4 to be turned on, and provides power supply to the power output mechanism 5, and the power output mechanism 5 outputs system control power to complete the control task of this device.

[0034] The plug-in switch 8 is arranged at the near entrance of the insertion hole of the plug-in lock needle 6, and the mechanical linkage button of the lever brake mechanism 7 and the micro switch 3 is arranged at the far entrance of the insertion hole of the plug-in lock needle 6.

[0035] Another embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] An electromechanical brake control device comprises a plug-in lock pin 6, a plug-in switch 8, a controller 1, a power supply 2, a micro switch 3, an electric control switch 4, a lever brake mechanism 7 and a power output mechanism 5.

[0037] The plug-in lock pin 5 is made of a metal conductive material, which controls the plug-in switch 8, the micro switch 3 and the lever brake mechanism 7. Figure 1 A working principle diagram of an electromechanical brake control device.

[0038] When the plug-in lock pin 6 is inserted, the plug-in switch 8 is turned on and provides a low-level signal to the controller 1, the microswitch 3 disconnects the power supply, and the lever brake mechanism 7 locks the power output mechanism; when the plug-in lock pin 6 is pulled out, the plug-in switch 8 is disconnected and provides a high-level start signal to the controller 1, the microswitch 3 connects the power supply 2, and the lever brake mechanism 7 releases the power output mechanism. Once the controller 1 gives a control signal, the electric control switch 4 is turned on, and the power output mechanism 5 outputs the system control power to complete the control task of this device.

[0039] The plug-in switch 8 is turned on and off by plugging and pulling the lock pin 6. Because the plug-in lock pin 6 is made of a metal conductive material, when the plug-in lock pin 6 is inserted, the plug-in switch 8 is turned on; when the plug-in lock pin 6 is pulled out, the plug-in switch 8 is disconnected.

[0040] The micro switch 3 also switches on and off the power supply 5 by plugging and pulling out the lock pin 6. When the plug-in lock pin 6 is inserted, the micro switch 3 is subjected to mechanical pressure to turn off the power supply, and the power output mechanism 5 cannot work without electric energy.

[0041] The lever brake mechanism 7 also completes the mechanical control of locking and releasing the power output mechanism 5 by plugging and pulling the lock pin 6. When the plug-in lock pin 6 is inserted, the lever brake mechanism 7 locks the power output mechanism, and the power output mechanism 5 cannot work.

[0042] The controller 1 is provided with a high-level start signal by the plug-in switch 6. When the plug-in lock pin 6 is inserted, the plug-in switch 8 is turned on and provides a low-level signal to the controller 1, and the controller 1 does not start to output control instructions; when the plug-in lock pin 6 is pulled out, the plug-in switch 8 is turned off and provides a high-level start signal to the controller 1, and the controller 1 starts working, outputs control instructions when the working conditions are met, controls the electronic control switch 8 to be turned on, and provides power supply to the power output mechanism 5, and the power output mechanism 5 outputs system control power to complete the control task of this device.

[0043] The plug-in lock pin 6, as a functional component of the system, provides a system start signal and limits the power output mechanism from erroneous operation through mechanical and electrical means.

[0044] Application examples of this embodiment:

[0045] Application scenario 1: The ejection seat program controller used for tasks such as pilot ejection and life-saving not only provides a system start-up signal, but also limits the power output mechanism from erroneous operation through mechanical and electrical means.

[0046] Application scenario 2: The ejection seat program controller used for tasks such as ejection and life-saving of aerospace crew members not only provides a system start-up signal, but also limits the erroneous operation of the power output mechanism through mechanical and electrical means.

[0047] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable technicians familiar with the technical field to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent transformation or modification made according to the spirit and essence of the present invention should be included in the protection scope of the present invention.
