Those skilled in the art can reasonably design the magnetic attraction force between the magnetic assembly 30 and the magnetic conductive shell 50 according to the actual required magnetic attraction force, and will not be described in detail herein.
As shown in fig. 1 to 3, in an embodiment of the trigger button device 100 of the present invention, an end of the third cylinder 535 facing away from the second cylinder 531 is bent inward to form an adjusting ring 5351.
It can be appreciated that the existence of the adjusting ring 5351 can realize adjustment of the relative relationship between the amount of the magnetic conductive material on the first cylinder portion 511 and the amount of the magnetic conductive material on the second cylinder portion 531, thereby realizing adjustment of the magnetic attraction between the magnetic assembly 30 and the magnetic conductive shell 50, and further being beneficial to realizing constant force output under large displacement of the magnetic assembly 30.
In addition, it should be noted that, in the practical application process, due to the existence of the adjusting ring 5351, when the coil 10 is not energized, the magnetic assembly 30 will give an initial reaction force to the finger of the user through the output member, and the initial reaction force is the reference force generated by the magnetic circuit system formed by the magnetic assembly 30 and the magnetic conductive shell 50. Further, when the coil 10 is energized in the forward direction, the reaction force given to the user's finger by the output member will become "reference force+electromagnetic driving force"; and when the coil 10 is negatively energized, the reaction force imparted to the user's finger by the output member will become "reference force-electromagnetic driving force". The electromagnetic driving force is proportional to the current, and any force output in the section of reference force +/-electromagnetic driving force can be realized by combining different waveform control.
The invention also proposes an electronic device comprising a trigger button device 100 as described above, the specific structure of the trigger button device 100 being referred to the previous embodiments. Because the electronic device adopts all the technical schemes of all the embodiments, the electronic device at least has all the beneficial effects brought by all the technical schemes of all the embodiments, and the detailed description is omitted.
It will be appreciated that the electronic device may be a variety of operating handles, toy guns, virtual reality devices, augmented reality devices, and the like.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
