DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1 to 5 shown, an electromagnetic release for an aircraft simulator of the present utility model includes a plastic shell 1, a moving iron core 2, a pull rod 3, and a magnetic flux mechanism; the magnetic flux mechanism in the present utility model is the same as that in the background art, and is also composed of components such as a U-shaped frame 101, a magnet 102, a magnetic flux coil 103, a magnetic flux skeleton 104, and a magnetic flux cover plate 105. Its principle is also the same as that in the background art, that is, an electromagnet with a coil and a magnet inside. When the coil is energized, the magnetic force generated plus the elastic force of the spring is greater than the suction force of the magnet, and the button part will pop out. Consistent with the original patent, a main spring 4 is sleeved on the moving iron core 2 of the present utility model; one end of the moving iron core 2 and the pull rod 3 are fixedly connected to each other, and the fixed part of the two is located inside the magnetic flux mechanism. One end of the moving iron core 2 is placed inside the button reset mechanism. Different from the original patent, the button reset mechanism includes a button upper cover 10 and a button lower cover 11 that are connected to each other, omitting components such as a button spring and a button pin. The other end of the pull rod 3 of the present utility model is fixedly connected to a sleeve 5, and a secondary spring 6 is fixedly installed between the bottom of the sleeve 5 and the plastic shell 1; limit switches 7 are fixedly installed inside the plastic shell 1 and on both sides of the sleeve 5, and a switch button 71 is provided on the top of the limit switch 7; when the sleeve 5 is in a pressed state, the sleeve 5 can contact and press the switch button 71; when the sleeve 5 rebounds, the sleeve 5 is in a separated state from the switch button 71.

[0021] As Figure 4 shown: Two connecting pressure pieces 51 are symmetrically provided at one end of the sleeve 5 of the present utility model; the sleeve 5 presses the switch button 71 to open or separates and closes it through the two connecting pressure pieces 51. As Figure 5 shown, three pins are provided on the limit switch 7 of the present utility model. Two wires coming out of the magnetic flux coil inside the magnetic flux mechanism, one is directly connected to a copper sheet, and the other is connected to another copper sheet through the limit switch 7; the limit switch 7 is respectively connected to a signal copper sheet I 8 and a signal copper sheet II 9, that is, the limit switch 7 on the left side of the pull rod 3 is connected to the signal copper sheet I 8, and the limit switch 7 on the right side of the pull rod 3 is connected to the signal copper sheet II 9.

[0022] The functions that the present utility model can achieve are: 1. The button can be manually pressed to conduct the signal copper sheet; 2. The button can be manually pulled out to disconnect the signal copper sheet; 3. It can be ejected by power on; the working principle to achieve the above is:

[0023] 1. The signal copper sheet can be conducted by manually pressing the button: When it is not powered on, manually press the upper button cover 10. While the upper button cover 10 drives the moving iron core 2, the pull rod 3 and the sleeve 5 to move downward, the main spring 4 and the secondary spring 6 are compressed until the moving iron core 2 is attracted by the magnet 102. At this time, the connecting tab 51 of the sleeve 5 contacts the switch button 71 of the limit switch 7, and the switch button 71 of the limit switch 7 is in a pressed state, so that the signal copper sheet is conducted;

[0024] 2. The signal copper sheet of the button can be disconnected by manually pulling it out: Select to manually pull the upper button cover 10 upward. When the applied force is greater than the adsorption force of the magnet 102, the sleeve 5 can also be driven to release the switch button 71 of the limit switch 7, resulting in power off.

[0025] 3. It can pop out when powered on: When the main spring 4 is compressed (at this time, the two connecting tabs 51 of the sleeve 5 press the switch button 71 of the limit switch 7), apply 24V or 28V power to it, and the whole composed of the upper button cover 10, the lower button cover 11, the moving iron core 2, and the pull rod 3 will pop out. Under the action of the secondary spring 6, the sleeve 5 will also move forward, so that the switch button 71 of the limit switch 7 is released, and all things are powered off.

[0026] In addition, the limit switch 7 is connected to the signal copper sheet I 8 and the signal copper sheet II 9. When the sleeve 5 pops out, the electrical signals of the signal copper sheet I 8 and the signal copper sheet II 9 are disconnected, and vice versa. In the case of all disconnections, press the button, the pull rod 3 pushes the sleeve 5, the secondary spring 6 is compressed, the sleeve 5 squeezes the switch button 71 of the limit switch 7, and the circuit (two wiring copper sheets) and the electrical signal (two signal copper sheets) are both conducted. Finally, it should be noted that the limit switch of the present utility model has three pins, one is normally open, and the other is normally closed. As long as the pin for feedback electrical signal (connecting the signal copper sheet and the limit switch) is changed, the electrical signal can be reversed, that is, in the popped state, the electrical signal is conducted, and when pressed, it is disconnected.

[0027] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
