Description
Technical Field
The invention relates to the field of switches, in particular to a push type aviation switch.
Background
The aircraft is vibrated by factors such as airflow and engines, and impacts can also occur during landing. The large vibration and shock are not good for the normal operation of the switch, even cause the contact of the switch to be loose, thereby causing a series of faults and further affecting the normal safe flight of the aircraft. Statistically, the switch of a small airplane often has poor contact due to vibration impact, so that the shock resistance and stability of the switch are urgently required to be improved.
The utility model provides a high performance aviation toggle switch is proposed to the utility model for CN207909776U of bulletin number, is wavy reed through setting up the shape to make the ball among the driving lever device can stop steadily in the crooked contact site of reed, play the auto-lock effect, thereby improve the contact stability of switch contact. The high-performance aviation toggle switch compresses the reed by moving the ball, and the control reed is contacted with one of the pins at the two ends of the control reed, so that the switch function is realized.
The high-performance aviation toggle switch has three defects: firstly, in a very noisy vibration environment, after an operator dials a switch, the touch feedback of the switch is poor, and the operator cannot sense whether the switch is dialed in place; secondly, the requirements on the recovery capability and the service life of the reed are high, and the reed can recover the original shape after being deformed within a long service life, so that higher requirements are undoubtedly put forward on the manufacturing process of the reed; and thirdly, no standby guarantee exists, and once the reed is damaged, the switch function is invalid.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a push type aviation switch, which has the following effects: in a very noisy vibration environment, after an operator presses a switch, the operator can obviously perceive whether the switch is pressed in place; secondly, the requirement on the manufacturing process of the reed is not high, and the reed of the common microswitch can meet the requirement; and thirdly, standby guarantee is provided.
The above object of the present invention is achieved by the following technical solutions: a push type aviation switch comprises a push rod seat assembly, a push force conversion assembly and a micro switch assembly, wherein the push rod seat assembly comprises a push rod, the push rod is connected with the push force conversion assembly, the micro switch assembly comprises at least three micro switches, each micro switch is provided with a movable pin, a first fixed pin and a second fixed pin, a button seat is arranged between the push force conversion assembly and the micro switch assembly, a plurality of buttons are arranged on the button seat, the positions and the number of all the buttons are in one-to-one correspondence with all the movable pins, and the movable pins, the first fixed pins and the second fixed pins are all connected with power connection posts;
the push rod is used for pressing the force conversion assembly, the force conversion assembly is used for simultaneously pressing all the buttons, the buttons are used for pressing the movable pins, when the push rod does not press the force conversion assembly, the force conversion assembly presses the movable pins through the buttons, the movable pins are forced to be in contact with the first fixed pins, and at the moment, the switch is in a circuit breaking state;
the push force conversion assembly comprises two blocking parts, when the push rod presses the push force conversion assembly, the inner structure of the push force conversion assembly deforms, the deformed structure impacts one blocking part, meanwhile, the deformed structure causes the push force conversion assembly to release the button, the button releases the movable pin, the movable pin rebounds to be in contact with the second fixed pin, and the switch is in a closed circuit state;
when the push rod releases the press force conversion assembly, the deformed structure in the press force conversion assembly collides with the other blocking part when being recovered, and meanwhile, the structure of the recovered state leads the press force conversion assembly to press the button, so that the button presses the movable pin, the movable pin is forced to be in contact with the first fixed pin, and the switch is in a circuit breaking state at the moment.
By adopting the technical scheme, when the push rod is pressed by hand to cause the deformation structure in the pressure conversion assembly to impact one blocking part, crisp sound and sudden jump force generated by impact can be transmitted to an operator; when the hand does not apply force to the push rod, the push rod can be rebounded when the deformation structure in the force conversion assembly is restored to the original state, and simultaneously the other blocking part is impacted, so that crisp sound and sudden jump force generated by the impact can be transmitted to an operator. Therefore, in a noisy vibration environment, after the operator presses the switch, the operator can clearly perceive whether the switch is pressed in place.
The structure of the pressing reed (namely the movable pin) is adopted to replace the structure of the pressing reed along the length direction of the reed in the background technology, the deformation of the pressed reed is much smaller than the deformation of the pressed reed along the length direction of the reed, because the reed needs to be pressed twice along the length direction of the reed when one opening and closing action is completed, but the structure of the pressing reed is only required to press the reed once when one opening and closing action is completed, because the reed is in a pressed state when the aviation switch is in an open circuit (namely in an off state), and the state switched to be in the on state is the state of releasing the reed. Therefore, the structure of the pressing reed adopted by the invention has little influence on the service life of the reed, has low requirement on the manufacturing process of the reed, and can meet the requirement by adopting the reed on the common microswitch.

As shown in fig. 1, the force conversion assembly 3 includes a first elastic sheet 16 and a second elastic sheet 17 sequentially arranged from top to bottom, wherein the left end of the first elastic sheet 16 is positioned (clamped) and the right end is a movable end, and the right end of the second elastic sheet 17 is positioned (clamped) and the left end is a movable end. Spring sleeves 19 are fixed on the movable ends of the first elastic sheet 16 and the second elastic sheet 17, the two spring sleeves 19 are connected through a straight spring 18, and the end part of the straight spring 18 is sleeved on the spring sleeve 19. The second elastic sheet 17 is provided with an opening which is free from the straight spring 18, so that the deformation of the straight spring 18 is not blocked.
As shown in fig. 1, the pressing force conversion assembly 3 further includes two blocking portions 15, when the push rod 6 presses the pressing force conversion assembly 3, the internal structure of the pressing force conversion assembly 3 deforms, and the deformed structure impacts one blocking portion 15, and at the same time, the deformed structure causes the pressing force conversion assembly 3 to release the micro switch 7, and the switch is in an on state; when the push rod 6 releases the press force conversion component 3, the structure deformed in the press force conversion component 3 collides with the other blocking part 15 when being restored to the original state, and meanwhile, the structure restored to the original state causes the press force conversion component 3 to press the micro switch 7, and the switch is in an open circuit state at the moment.
The detailed process of deformation of the structure in the force transfer assembly 3 is as follows:
when the pressing cap 20 is pressed, the pressing cap 20 vertically presses the push rod 6 against the movable end of the first elastic sheet 16, so that the connecting end of the straight spring 18 and the first elastic sheet 16 is continuously lowered, and the straight spring 18 is continuously compressed, so that when the straight spring 18 reaches a horizontal state, the push rod 6 is completely compressed, the first elastic sheet 16 continues to press the first elastic sheet 16, the first elastic sheet 16 generates a downward pressure on one end of the straight spring 18, because the straight spring 18 cannot be continuously compressed, the connecting end of the straight spring 18 and the first elastic sheet 16 will bend downward, and the connecting end of the straight spring 18 and the second elastic sheet 17 is stationary, so when the connecting end of the straight spring 18 and the first elastic sheet 16 bends downward to a certain extent, the connecting end of the straight spring 18 and the second elastic sheet 17 will push the movable end of the second elastic sheet 17 upward (the pushing force will be referred to as "upward pushing force"), because the straight spring 18 is still in a compressed state, i.e. the straight spring 18 still has a downward-directed thrust on the free end of the second elastic strip 17, when the upward-directed thrust overcomes the downward-directed thrust, the free end of the second elastic strip 17 will momentarily bounce at a very fast rate, striking the upper blocking portion 15. When the hand does not press the push rod 6 any more, the second elastic piece 17 rebounds to the original position under the restoring force of the straight spring 18, so that the movable end of the second elastic piece 17 strikes the blocking part 15 below.
As shown in fig. 1, the microswitch assembly 4 comprises at least three microswitches 7, each microswitch 7 having a movable pin 8, a first fixed pin 9, a second fixed pin 10. A button seat 13 is fixed on the partition plate 12, a plurality of buttons 14 (only one button 14 can be seen in a row of buttons 14 in fig. 1) are arranged on the button seat 13, the positions and the number of all the buttons 14 correspond to those of all the movable pins 8 one by one, and the movable pins 8, the first fixed pins 9 and the second fixed pins 10 are all connected with the electric poles 11. When the aviation switch is in the open circuit state, the second elastic sheet 17 is normally pressed on all the buttons 14, and each button 14 is pressed on the movable pin 8 of the corresponding microswitch 7.
As shown in fig. 1, when the push rod 6 does not press the first elastic sheet 16, the second elastic sheet 17 presses the movable pin 8 through the button 14, the movable pin 8 is forced to contact with the first fixed pin 9, and the switch is in an off state; when the push rod 6 presses the first elastic sheet 16, the movable end of the second elastic sheet 17 springs upwards, so that the second elastic sheet 17 moves upwards away from the button 14, the button 14 releases the movable pin 8, and the movable pin 8 is restored to be in contact with the second fixed pin 10 because the movable pin 8 is a reed with shape restoring capability, and the switch is in an on state at the moment.
The advantages of the invention are as follows:
(1) when the push rod 6 is pressed by hand to cause the deformation structure in the pressure conversion component 3 to impact one blocking part 15, crisp sound and sudden jump force generated by impact can be transmitted to an operator; when the hand does not apply force to the push rod 6, the push rod 6 can be rebounded when the deformation structure in the force conversion assembly 3 is restored to the original state, and simultaneously the other blocking part 15 is impacted, so that crisp sound and sudden jump force generated by the impact can be transmitted to an operator. Therefore, in a noisy vibration environment, an operator can clearly perceive whether the switch is pressed in place after pressing the switch.
(2) The structure of the pressing reed (namely the movable pin 8) is adopted to replace the structure of pressing the reed along the length direction of the reed in the background technology, the deformation of the reed when being pressed is much smaller than the deformation of the reed when being pressed along the length direction of the reed, because the reed needs to be pressed twice along the length direction of the reed when completing one opening and closing action, the structure of the pressing reed adopted by the invention only needs to press the reed once when completing one opening and closing action, because the reed is in a pressed state when the aviation switch is in an open circuit (namely in an off state), and the state switched to be in the on state is the state of releasing the reed. Therefore, the structure of the pressing reed adopted by the invention has little influence on the service life of the reed, has low requirement on the manufacturing process of the reed, and can meet the requirement by adopting the reed on the common microswitch.
(3) Because the reed is pressed in the state that the aviation switch is in the open circuit state by adopting the pressing reed structure, the reed cannot shake and mistakenly touch the second fixed pin 10 to cause the misoperation of the aviation switch no matter how much vibration is generated by the aircraft, and the pressing reed structure is an advantage of the invention relative to other pressing switches.
(4) Because at least three micro-switches 7 are integrated in the micro-switch assembly 4, the movable pins 8, the first fixed pins 9 and the second fixed pins 10 of the micro-switches 7 can be used in a matched mode, for example, the movable pin 8 of one micro-switch 7 can form a loop with the second fixed pin 10 of another micro-switch 7, even if part of the movable pins 8 or part of the second fixed pins 10 are damaged, the movable pins 8 and the second fixed pins 10 can form a loop, so that the aviation switch can normally work, and the aviation switch has a standby guarantee. For example, as shown in fig. 4, there may be A, B, C three uses for the four microswitches 7, wherein the connection of the second and third microswitches 7 from top to bottom results in more uses.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
