In this embodiment, the plurality of adjustment grooves 50a are formed only at one end of the first barrel portion 511 that is away from the second barrel portion 531, and the plurality of adjustment grooves 50a are provided at intervals in the circumferential direction of the first barrel portion 511.
It can be understood that the existence of the adjusting groove 50a can save the material of the magnetic conductive shell 50 and avoid waste; on the other hand, the relative relationship between the usage amount of the magnetic conductive material on the first barrel portion 511 and the usage amount of the magnetic conductive material on the second barrel portion 531 can be adjusted, so that the magnetic attraction between the magnetic assembly 30 and the magnetic conductive shell 50 can be adjusted, and the constant force output of the magnetic assembly 30 under large displacement can be realized.
Of course, in other embodiments, the adjustment groove 50a may be formed only at the end of the third barrel portion 535 away from the second barrel portion 531; alternatively, the adjustment groove 50a opens at both the end of the first barrel portion 511 facing away from the second barrel portion 531 and the end of the third barrel portion 535 facing away from the second barrel portion 531. Those skilled in the art can design the magnetic attraction force between the magnetic assembly 30 and the magnetic conductive shell 50 according to the actual requirement, 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 cylindrical body portion 535 away from the second cylindrical body portion 531 is bent inward to form an adjusting ring 5351.
It can be understood that, the existence of the adjusting ring 5351 can realize the adjustment of the relative relationship between the usage amount of the magnetic conductive material on the first cylindrical portion 511 and the usage amount of the magnetic conductive material on the second cylindrical portion 531, thereby realizing the adjustment of the magnetic attraction between the magnetic assembly 30 and the magnetic conductive shell 50, and further facilitating the realization of the constant force output under the large displacement of the magnetic assembly 30.
In addition, it should be noted that, in practical applications, when the coil 10 is not energized due to the existence of the adjusting ring 5351, the magnetic assembly 30 will give an initial reactive force to the user's finger through the output member, and the initial reactive force is a 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"; when the coil 10 is energized negatively, the reaction force given to the user's finger by the output member becomes "reference force — electromagnetic driving force". The magnitude of the electromagnetic driving force is in direct proportion to the magnitude of the current, and arbitrary force output in a range of 'reference force +/-electromagnetic driving force' can be realized by combining different waveform control.
The present invention also provides an electronic device including the trigger button device 100 as described above, and the specific structure of the trigger button device 100 refers to the foregoing embodiments. Since the electronic device adopts all the technical solutions of all the embodiments, at least all the beneficial effects brought by all the technical solutions of all the embodiments are achieved, and no further description is given here.
It is to be appreciated that the electronic device can be any of a variety of operating handles, toy guns, virtual reality devices, augmented reality devices, and the like.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
