Fig. 2, Fig. 3 and Fig. 4 are please referred to, the first embodiment of the utility model proposes a kind of fold mechanism, including 1 He of headband Fold arm 2.

Specifically, the folding arm 2, for being fixedly connected with ear-hang 3, the headband 1 passes through locating shaft 4 and the folding Arm 2 is rotatablely connected, and the folding arm 2 is equipped with location hole 21, and the locating shaft 4 is located in the location hole 21, the positioning Axis 4 is fixedly connected with the headband 1, and damping spring plate 22, the locating shaft are equipped between the location hole 21 and the locating shaft 4 It is squeezed state between 4 and the damping spring plate 22.

The advantage of the utility model is, due to generating extruding, locating shaft 4 and resistance between locating shaft 4 and damping spring plate 22 Frictional force can occur between Buddhist nun's elastic slice 22, i.e., generate frictional force between folding arm 2 and headband 1, turn to a positioning when folding arm 2 When setting, due to the effect of frictional force, it will not freely swing.

Specifically, the headband 1 and the junction for folding arm 2 are equipped with folding rack 11, the locating shaft 4 with it is described Folding rack 11 is fixedly connected.

Since locating shaft 4 is arranged on folding rack 11, the effect of folding rack 11 is and folds the rotation connection of arm 2, Its major function, which is to protrude locating shaft 4, fixes, convenient for folding the connection of arm 2 and locating shaft 4.

Referring to Fig. 5, in the present embodiment, the locating shaft 4 is fixedly connected by screw 12 with the folding rack 11, The locating shaft 4 is equipped with the first limited block 41, corresponding first limit of the folding rack 11 towards the folding rack 11 Block 41 is equipped with limiting slot 13, and first limited block 41 is located in the limiting slot 13.

It is understood that folding arm 2 and head even if locating shaft 4 is fixedly connected by screw 12 with folding rack 11 Under rotation repeatedly with 1, the relative rotation between locating shaft 4 and folding rack 11 is inevitably resulted in, and then leads to screw 12 Fixation loosens, and the first limited block 41 cooperation limiting slot 13 can prevent that opposite turn occurs between locating shaft 4 and folding rack 11 It is dynamic.

In addition, the damping spring plate 22 be wavy strip structure, around the locating shaft 4 arrange, and with it is described It folds arm 2 to be fixedly connected, then the one of locating shaft 4 week can generate frictional force with damping spring plate 22, what the extruding compared with single-point generated Frictional force is bigger.And due to the elasticity of damping spring plate 22 itself, allow to occur certain elastic deformation, it is enabled to pass through damping spring plate 22 occur elastic deformations to turn folding arm 2.

Specifically, the damping spring plate 22 includes 2 sub- elastic slices, be equipped on the inner wall of the location hole 21 in opposite directions 2 it is recessed Slot 23, the both ends of the bullet piece are respectively positioned in 2 grooves 23, and the position of damping spring plate 22 is fixed with this.Groove 23 Can be regarded as to accommodate the small gaps of two sub- elastic slice thickness realizes fixation when group elastic slice is inserted into groove 23.

In the present embodiment, the locating shaft 4 is cylindrical-shaped structure, and the surface of the locating shaft 4 is equipped with several fixture blocks 42, The fixture block 42 is used to be clamped with the damping spring plate 22.It can make to fold when arm 2 rotates by fixture block 42 and issue sound, increase machine Tool sense, and when fixture block 42 is located inside the circular arc of damping spring plate 22, it can realize clamping, folding arm 2 is more stable, is not susceptible to certainly By swinging.

In other embodiments, the locating shaft 4 or polygonal column structure (not shown), the rib of locating shaft 4 Angle can be clamped with damping spring plate 22, without additional setting fixture block 42.

In addition, the edge of the location hole 21 is equipped with the second limited block 24, second limited block 24 is for limiting institute State the position of damping spring plate 22.

Referring to Fig. 1, the second embodiment of the utility model proposes a kind of earphone, which includes at least first embodiment In fold mechanism.

In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show The description of example " or " some examples " etc. means specific features, structure, material or spy described in conjunction with this embodiment or example Point is contained at least one embodiment or example of the utility model.In the present specification, to the schematic table of above-mentioned term Stating may not refer to the same embodiment or example.Moreover, particular features, structures, materials, or characteristics described can be It can be combined in any suitable manner in any one or more embodiment or examples.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
