[0014] The present invention is further described in detail below by means of specific embodiments in combination with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0015] See also Figures 1 to 4 , the figure shows a double-stroke magnetic holding trigger switch, which can be used in airborne control equipment, shipborne control equipment or other field control equipment.

[0016] The dual-stroke magnetic holding trigger switch comprises: a switch housing 1, a trigger button 2, a fixed mounting seat 3, a first-stroke trigger assembly 4, a second-stroke trigger assembly 5, etc.

[0017] The switch housing 1 has a housing built-in space and a housing lateral opening communicating with the housing built-in space. The housing built-in space has the fixed mounting seat 3, the first-stage trigger assembly 4, the second-stage trigger assembly 5, the magnetic holding assembly 6, etc.

[0018] The trigger button 2 is rotatably mounted on the lateral opening of the housing to enable the trigger button 2 to be pulled laterally. Specifically, a cylindrical pin is provided at the upper end of the trigger button 2. The cylindrical pin is fixed to a preset hole of the switch housing 1. The trigger button 2 can be pulled laterally around the cylindrical pin.

[0019] The fixed mounting seat 3 has a first accommodating blind hole and a second accommodating blind hole below the first accommodating blind hole. The opening of the first accommodating blind hole and the opening of the second accommodating blind hole are both lateral to the trigger button 2.

[0020] The one-stage stroke trigger assembly 4 has a one-stage stroke rod 41, a one-stage micro switch 42, a one-stage compression spring 43, a one-stage switch reed 44, etc. The one-stage stroke rod 41 is matched with the axial hole of the first accommodating blind hole. There is a gap between the trigger button 2 end of the one-stage stroke rod 41 and the inner surface of the trigger button 2. The one-stage stroke rod 41 has a stroke rod shoulder. The stroke rod shoulder of the one-stage stroke rod 41 abuts against the one-stage compression spring 43 inside the first accommodating blind hole. The stroke rod shoulder of the one-stage stroke rod 41 abuts against the switch button of the one-stage micro switch 42 through the one-stage switch reed 44. In this embodiment, the one-stage micro switch 42 is above the one-stage stroke rod 41. By shifting the one-stage stroke rod 41 toward the fixed mounting seat 3, the one-stage stroke rod 41 can drive the one-stage switch reed 44 to press the switch button of the one-stage micro switch 42 through its stroke rod shoulder, thereby realizing the switching action of the one-stage micro switch 42.

[0021] The two-stage stroke trigger assembly 5 has a two-stage stroke rod 51, a two-stage micro switch 52, a two-stage compression spring 53, a two-stage switch reed 54, etc. The two-stage stroke rod 51 is matched with the axial hole of the second accommodating blind hole. The trigger button 2 end of the two-stage stroke rod 51 is against the inner surface of the trigger button 2. The two-stage stroke rod 51 has a stroke rod shoulder. The stroke rod shoulder of the two-stage stroke rod 51 is against the two-stage compression spring 53 inside the second accommodating blind hole. The stroke rod shoulder of the two-stage stroke rod 51 is against the switch button of the two-stage micro switch 52 through the two-stage switch reed 54. In this embodiment, the two-stage micro switch 52 is below the two-stage stroke rod 51. The two-stage stroke rod 51 is shifted toward the fixed mounting seat 3 , and the two-stage stroke rod 51 can drive the two-stage switch reed 54 to press the switch button of the two-stage micro switch 52 through its stroke rod shoulder, thereby realizing the switching action of the two-stage micro switch 52 .

[0022] In one embodiment, the switch housing 1 and / or the trigger button 2 are made of polyethylene plastic.

[0023] In one embodiment, the one-stage micro switch 42 and / or the two-stage micro switch 52 are both commercially available products. The one-stage travel rod 41 and / or the two-stage travel rod 51 are made of aluminum. The one-stage compression spring 43 and / or the two-stage compression spring 53 are made of stainless steel. The one-stage switch reed 44 and / or the two-stage switch reed 54 are made of beryllium tin copper.

[0024] In one embodiment, the number of the first-stage travel rod 41 and / or the second-stage travel rod 51 is not limited to one.

[0025] The two-stage travel trigger assembly 5 and the one-stage travel trigger assembly 4 are opened sequentially, and the specific principle is as follows: the trigger button 2 is pulled sideways, and the trigger button 2 end of the two-stage travel rod 51 is against the trigger button 2, and the trigger button 2 drives the two-stage travel rod 51 to shift toward the fixed mounting seat 3, and the two-stage compression spring 53 is compressed by the travel rod shoulder of the two-stage travel rod 51, generating an obvious trigger pressing feedback force. In the process, the travel rod shoulder of the two-stage travel rod 51 presses the switch button of the two-stage micro switch 52 through the deformation of the two-stage switch reed 54, that is, the one-stage travel trigger function is activated. Continue to pull the trigger button 2 sideways, and the trigger button 2 end of the one-stage travel rod 41 and the trigger button 2 end of the two-stage travel rod 51 are both against the trigger button 2. The trigger button 2 drives the one-stage travel rod 41 and the two-stage travel rod 51 to shift toward the fixed mounting seat 3 at the same time. The trigger pressing feedback force generated by the compression of the first stage compression spring 43 by the travel rod shoulder of the first stage travel rod 41 and the trigger pressing feedback force generated by the compression of the second stage compression spring 53 by the travel rod shoulder of the second stage travel rod 51 are superimposed, and the trigger feedback force with a greater travel pressing effect is generated. In addition, during the process, the travel rod shoulder of the first stage travel rod 41 presses the switch button of the first stage micro switch 42 through the deformation of the first stage switch reed 44, thereby activating the second stage travel trigger function. In this way, two-stage trigger travel and double-stroke tactile sensation are achieved.

[0026] The dual-stroke magnetic holding trigger switch further comprises: a magnetic holding assembly 6. The magnetic holding assembly 6 comprises an electromagnetic coil 61, a permanent magnet 62, a magnetic holding micro switch 63 and the like.

[0027] The electromagnetic coil 61 surrounds the outer sides of the first stroke rod 41 and the second stroke rod 51. The electromagnetic coil 61 is fixed. The electromagnetic coil 61 generates magnetic field force when it is energized. The permanent magnet 62 is fixed on the inner surface of the trigger button 2. The permanent magnet 62 attracts the electromagnetic coil 61 after it is energized through its own magnetic field force. In this way, the effect of magnetic retention and buffer recovery of the double-stroke trigger is achieved.

[0028] In one embodiment, the electromagnetic coil 61 is made of an enameled copper round coil, and the permanent magnet 62 is made of a cubic NdFeB permanent magnet.

[0029] Whether the electromagnetic coil 61 is energized is controlled by the magnetic holding micro switch 63. The switch button of the magnetic holding micro switch 63 is provided with a magnetic holding switch reed 630, and the magnetic holding switch reed 630 is in the motion path of the trigger button 2. That is, the trigger button 2 can press the switch button of the magnetic holding micro switch 63 through the deformation of the magnetic holding switch reed 630 to energize the electromagnetic coil 61.

[0030] After being energized, the electromagnetic coil 61 generates a magnetic field force that attracts each other relative to the permanent magnet 62. The magnetic field force is smaller than the restoring force of the first-stage compression spring 43 and / or the second-stage compression spring 53. That is, the magnetic field force cannot completely offset the restoring force of the first-stage compression spring 43 and / or the second-stage compression spring 53, but it can reduce the force applied by the user to the trigger button 2, and easily realize the function of continuous pressing.

[0031] See also Figure 5 The magnetic holding principle of the double-stroke magnetic holding trigger switch is briefly described as follows: when a triggering force is applied to the trigger button 2, when the trigger button 2 abuts against the magnetic holding micro switch 63 and presses the magnetic holding micro switch 63, the electromagnetic coil 61 is energized and generates a magnetic field force that attracts the permanent magnet, forming a magnetic holding effect. If the force is canceled, the trigger button 2 is reset under the action of the first-stage compression spring 43 and the second-stage compression spring 53. Since the direction of the magnetic field force is opposite to the restoring force of the first-stage compression spring 43 and the second-stage compression spring 53, the magnetic holding effect can play a certain buffering role on the trigger button 2 during the key resetting process.

[0032] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
