[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Please refer to Figures 1 to 7 , which shows a quick trigger mechanism for a micro switch assembly.

[0032] The quick trigger mechanism is composed of components such as a micro switch assembly 1, a rotating piece body 2, an actuating piece body 3, a reed piece body 4, and a tension spring body 5. Preferably, the quick trigger mechanism further includes a fixed support 6.

[0033] The micro switch assembly 1 has a micro switch 11. A switch button 110 is formed on the top surface of the micro switch 11. Pressing the switch button 110 downwards can realize the switching function of the micro switch 11. The number of the micro switches 11 can be 1, 2 or more. When the number of the micro switches 11 is greater than 1, the micro switches 11 can be arranged in sequence from front to back.

[0034] The rotating piece body 2 is arranged above the micro switch assembly 1. The rotating piece body 2 is a downward convex arc section extending in the left - right direction. The bottom surface of the rotating piece body 2 abuts against the top surface of the switch button 110. A rotating piece left sleeve 21 extending in the front - back direction is formed at the left end of the rotating piece body 2. A rotating piece fixing shaft 7 is inserted into the rotating piece left sleeve 21. The rotating piece fixing shaft 7 is fixed. The rotating piece body 2 can rotate up and down around the rotating piece fixing shaft 7.

[0035] Preferably, the rotating piece fixing shaft 7 can be fixed on the fixed support 6. Specifically, the fixed support 6 is arranged above the rotating piece body 2. A first connecting ear of the support is formed on the bottom surface of the fixed support 6. A first connecting hole 61 is formed in the first connecting ear of the support. The rotating piece fixing shaft 7 is inserted through the first connecting hole 61. The first connecting hole 61 is fixedly connected to the rotating piece fixing shaft 7 to fix the rotating piece fixing shaft 7. Further, the left sleeve 21 of the rotating piece can be a continuous section or a discontinuous section (i.e., disconnected front and back), and the right sleeve 22 of the rotating piece can be a continuous section or a discontinuous section (i.e., disconnected front and back).

[0036] A right sleeve 22 of the rotating piece body 2 extending in the front-back direction is formed at the right end of the rotating piece body 2. A tension spring moving shaft 8 is inserted through the right sleeve 22 of the rotating piece. The tension spring moving shaft 8 is integrated with the rotating piece body 2 to move synchronously.

[0037] The actuator body 3 is arranged above the rotating piece body 2. The bottom surface of the actuator body 3 abuts against the top surface of the rotating piece body 2. Preferably, the fixed support 6 is formed with a support guiding hole 62 extending in the vertical direction. The actuator body 3 is located inside the support guiding hole 62 (with shaft-hole fit between the two) and can move up and down along the support guiding hole 62.

[0038] The reed body 4 is arranged above the microswitch assembly 1 and on the right side of the rotating piece body 2. The reed body 4 extends in the vertical direction and faces the rotating piece body 2. The reed body 4 has a reed vertical section 41 and a reed flange section 42. A reed limiting shaft 10 extending in the front-back direction is arranged on the right side of the reed vertical section 41, and the right surface of the reed vertical section 41 abuts against the left surface of the reed limiting shaft 10. A portion 411 of the reed vertical section 41 above the reed limiting shaft 10 is fixed. If a rightward external force is applied to a portion 412 of the reed vertical section 41 below the reed limiting shaft 10, the portion 412 of the reed vertical section 41 below the reed limiting shaft 10 will bend rightward around the reed limiting shaft 10. Preferably, the portion of the reed vertical section 41 below the reed limiting shaft 10 is trapezoidal with a larger upper part and a smaller lower part.

[0039] The reed flange section 42 is located below the reed vertical section 41. The reed flange section 42 projects integrally to the left starting from the imaginary extension plane of the reed vertical section 41. The reed flange section 42 has a flange section upper edge 421 and a flange section lower edge 422. The flange section upper edge 421, the flange section lower edge 422 and the imaginary extension plane form a triangle or a quasi-triangle. The right swivel sleeve 22 abuts against the flange section upper edge 421. Preferably, there is also a flange section reinforcing rib 43, which is arranged on the right side of the reed flange section 42 and is located between the flange section upper edge 421 and the flange section lower edge 422. The flange section reinforcing rib 43 is used to strengthen the overall strength of the reed flange section 42 and prevent deformation under stress.

[0040] The tension spring body 5 is arranged above the microswitch assembly 1 and on the right side of the swivel body 2. The tension spring body 5 extends vertically. The upper end of the tension spring body 5 is fixed. There is a tension spring fixing shaft 9 corresponding to the upper end of the tension spring body 5. The tension spring fixing shaft 9 can be fixed on the fixed support 6. Specifically, a second connecting ear of the support is formed on the top surface of the fixed support 6. A second connecting hole 63 is formed in the second connecting ear of the support. The tension spring fixing shaft 9 is passed through the inside of the second connecting hole 63. The second connecting hole 63 is fixedly connected to the tension spring fixing shaft 9 to fix the tension spring fixing shaft 9. A hook portion 51 is formed at the upper end of the tension spring body 5 to hook on the tension spring fixing shaft 9.

[0041] The lower end of the tension spring body 5 is a movable end. The lower end of the tension spring body 5 is fixedly connected to the tension spring movable shaft 8 to support the tension spring movable shaft 8. Preferably, a hook portion 52 is formed at the lower end of the tension spring body 5 to hook on the tension spring movable shaft 8. If the right swivel sleeve 22 is a discontinuous section, the hook portion 52 at the lower end of the tension spring body 5 is exactly at the disconnection distance of the right swivel sleeve 22.

[0042] Further, a support receiving groove 64 opening to the right is formed on the right surface of the fixed support 6. A part 411 of the reed vertical section 41 above the reed limiting shaft 10 is received inside the support receiving groove 64. The support receiving groove 64 is fixedly connected to the part 411 of the reed vertical section 41 above the reed limiting shaft 10. A support receiving hole 65 opening to the right is formed on the left surface of the support receiving groove 64. The tension spring body 5 is located inside the support receiving hole 65. The tension spring body 5 is circumferentially limited by the support receiving hole 65 and the part 411 of the reed vertical section 41 above the reed limiting shaft 10. With the above design, the crosstalk of the reed body 4 and the tension spring body 5 can be restricted.

[0043] Preferably, third connection holes 66 are formed in front of and behind the support accommodating groove 64. A reed limiting shaft 10 is inserted through the third connection holes 66. The third connection holes 66 are fixedly connected to the reed limiting shaft 10 to fix the reed limiting shaft 10.

[0044] The working principle of the quick trigger mechanism is as follows: Define the position where the centers of the rotating piece fixed shaft 7, the tension spring movable shaft 8, and the center of the reed flange section 42 (i.e., the joint of the upper edge 421 and the lower edge 422 of the flange section) are collinear as the critical position A. Apply a downward pressure to the actuator body 3. The actuator body 3 moves downward along the support guiding hole 62 and drives the rotating piece body 2 to rotate downward around the rotating piece fixed shaft 7 from the initial position, so that the right sleeve 22 of the rotating piece moves downward along the reed flange section 42: Before the critical position A, the reed flange section 42 is squeezed to the right by the rotating piece body 2, and the reed flange section 42 always provides an upward elastic force (the upward elastic force is generated by the rightward bending of the part 412 of the reed vertical section 41 below the reed limiting shaft 10) to the right sleeve 22 of the rotating piece to prevent the rotating piece body 2 from moving downward; After the critical position A, the rotating piece body 2 can no longer squeeze the reed flange section 42 to the right, and the reed flange section 42 always provides a downward elastic force (the downward elastic force is generated by the rightward bending of the part 412 of the reed vertical section 41 below the reed limiting shaft 10) to the right sleeve 22 of the rotating piece to promote the downward movement of the rotating piece body 2; During the downward rotation of the rotating piece body 2, the tension spring movable shaft 8 moves synchronously with the rotating piece body 2, causing the tension spring body 5 to deform and elongate; If the downward pressure is withdrawn, the rotating piece body 2 returns to the initial position under the upward pulling force (the upward pulling force is greater than the downward elastic force) generated by the deformation and elongation of the tension spring body 5.

[0045] Utilize the deformation and mutation of the reed body 4 to achieve the quick trigger of the switch button 110, and utilize the sudden release of the elastic potential energy of the reed body 4 to achieve the pressing tactile feedback, improving the reliability of the pressing operation and the level of human-machine ergonomics.

[0046] The above only represents the implementation modes of the present invention, and its description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
