The present invention will be further described with attached drawing combined with specific embodiments below.
The utility model is a kind of earphone rotary dampening mechanism, as shown in FIGS. 1 and 2 comprising: earphone base 1 is mounted on
Rotating device 20 on earphone base 1 and the connector 6 being connect with rotating device 20.
Earphone base 1 generally use plastic material production, in headphone usually as constitute headband component,
Installation for rotating device 20.
As shown in connection with fig. 2,1 end of earphone base is formed with an assembling groove 10, and the assembling groove 10 is for pacifying
Fill rotating device 20.Left and right locating slot 11,12 is formed on the left and right sides inner wall of assembling groove 10.It is recessed in assembly simultaneously
The side of 10 left and right sides of slot has been separately formed positioning pin 13 and fixing threaded hole 14.
In conjunction with shown in Fig. 2 to Fig. 7, the rotating device 20 includes: the left and right otic placode being fixedly connected with earphone base 1
31,32, the circular shaft 4 being fixedly connected between left and right otic placode 31,32 and the rotating member 5 with 4 shaft hole matching of circular shaft.
The left and right otic placode 31,32 is symmetrical arranged, and is fixed in above-mentioned left and right locating slot 11,12.Left and right positioning
The moulding of slot 11,12 is corresponding with left and right otic placode 31,32 moulding, enables left and right otic placode 31,32 respectively and can be fixed on inlay card and is left and right
In locating slot 11,12.In addition, the end outward bending in left and right otic placode 31,32 is formed with left and right fixed plate 311,321；Institute
Offered in the left and right fixed plate 311,321 stated pin hole 312,322 corresponding with above-mentioned positioning pin 13 and fixing threaded hole 14 and
Screw hole 313,323.When installation, positioning pin 13 plays further positioning action with the cooperation of corresponding pin hole 312,322, passes through simultaneously
Screw and fixing threaded hole 14, being threadedly engaged for screw hole 313,323 enable left and right otic placode 31,32 be fixed on earphone base 1.
The circular shaft 4 uses cross section for circular metal shaft, both ends with it is fixed with left and right otic placode 31,32 respectively
Connection, the mode used for shaft hole matching, i.e., offered respectively on left and right otic placode 31,32 with circular shaft 4 cooperation axis hole 310,
320.In order to guarantee that the two will not produce relative rotation, the both ends of circular shaft 4 are similarly, described using noncircular cross section moulding
Axis hole 310,320 using corresponding non-circular moulding.
The rotating member 5 includes: integrally formed circular groove 51 and interconnecting piece 52.Circular groove 51 is a unclosed circle
Slot.The interconnecting piece 52 includes the extension plate 521 extended to form along 51 edge of circular groove and is located at 521 two sides of extension plate
The connecting plate 522 of bending forming.
Above-mentioned circular groove 51 with circular shaft 4 for connecting, and interconnecting piece 52 with connector 6 for connecting.Wherein, the circular groove
51 are coated on circular shaft 4, and using interference fit between circular groove 51 and circular shaft 4, i.e., are interference fitted by circular groove 51 and circular shaft 4
Pressure is generated between circular shaft surface afterwards, to obtain the connection of fastening, and while enabling rotating member 5 rotate forms damping.Damping size can
To determine according to the tolerance being interference fitted before circular groove 51 and circular shaft 4, while also depending on coefficient of friction between the two.In general,
The aperture of circular groove 51 is smaller, and the holding active force generated to circular shaft 4 is bigger, and it is bigger to be formed by damping.Due to circular groove 51
Cooperate between circular shaft 4 using periphery, contact surface between the two is larger, it is possible to form stable damping.Together
When, it therebetween can be relatively fixed in any angle realization, to realize linear rotational positioning.
The connector 6 include: attachment base 61 and with the integrally formed connection pin shaft 62 of attachment base 61, the connection
The mounting groove 610 that seat 61 sandwiches rotating member 5 with one, two connecting plates 522 of the interconnecting piece 52 stick on mounting groove respectively
610 opposite inner walls, and be fixedly connected with connecting plate 522 with 610 inner wall of mounting groove of corresponding side by rivet 7.
In order to further realize being stably connected between connector 6 and rotating member 5, the connecting plate of the interconnecting piece 52
It is formed with protrusion 523 on 522 lateral walls, offers corresponding card slot in the position of 610 inner wall respective protrusions 523 of mounting groove
611.It is positioned by the inlay card between protrusion 523 and card slot 611, realizes further consolidating between attachment base 61 and interconnecting piece 52
Connection.
In addition, the attachment base 61 is formed with the groove 612 cooperated with circular shaft 4, the circular shaft 4 falls into the groove
In 612.
When using the utility model, the earpiece of headphone is connected to connector 6 by the way of shaft hole matching
It connects on pin shaft 62, realizes horizontally rotating for earpiece.Meanwhile when needing to rotate earpiece in the vertical direction, it is only necessary to hold
Earpiece, then time certain external force, overcomes the damping of rotating member 5 that the angular adjustment of earpiece in the vertical direction can be realized.
Since the power that user applies acts on earpiece, the arm of force of the external force is enabled to increase by earpiece, so not needing Fei Tai great 's
Power can realize the adjustment of earpiece angle.Meanwhile the torque that the gravity of earpiece itself generates is not enough to that rotating member 5 is overcome to damp
Torque, so earpiece is not in automatic to slide the problem of resetting.According to actual test, the damping formed using this structure
After mechanism can be with folding headset earpiece 7000 times, earpiece is still able to maintain opposite rotational positioning.
It certainly, is not to limit the utility model and implement the foregoing is merely specific embodiment of the utility model
Range, all equivalent change or modifications done according to structure, feature and principle described in present utility model application the scope of the patents, should all wrap
It includes in present utility model application the scope of the patents.
