Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model is further introduced and explanation, but be not limited to this.
Extremely shown in Figure 5 such as Fig. 1, a kind of foldable earphone structure of the utility model, comprise headband 10 and two ear casing assemblies 20 that connect with headband 10 two ends, also comprise for connecting the rotation coupling block 30 of headband 10 with ear casing assembly 20, upper end and headband 10 hinge-coupled of rotation coupling block 30, lower end and ear casing assembly 20 rotary being actively coupled of rotation coupling block 30.
The two ends of headband 10 are provided with flute profile lug boss 11, flute profile lug boss 11 is provided with horizontal pin-and-hole 111 and is positioned at middle open slot 112, the upper end of rotation coupling block 30 is provided with for the protruding pinna 31 that embeds in the open slot 112, pass the hinge hole 313 that horizontal pin-and-hole 111 and protruding pinna 31 are provided with by hinge 90 again, consisted of the hinge-coupled of headband 10 with rotation coupling block 30.
Be provided with the detent mechanism that is made of positioning convex point and detent in the upper end of rotation coupling block 30 and the contact-making surface of headband 10: open slot 112 both sides are provided with positioning convex point 113; The both sides of protruding pinna 31 are provided with detent 311, and wherein one group of positioning convex point and detent are used for the location after folding, another group positioning convex point and the location of detent for full open position.Its principle is: positioning convex point and detent be not at once, produce certain pretightning force between protruding pinna and the flute profile lug boss because of crimp, thereby resistance when having increased rotation coupling block and headband and rotating, and when being in folded state or full open position, positioning convex point is corresponding with detent, there is not pretightning force between protruding pinna and the flute profile lug boss, both realized the location of folded state and full open position, so that there is not the existence of pretightning force between protruding pinna and the flute profile lug boss yet, be conducive to keep the locating effect between the two, thereby can improve useful life.
For making protruding pinna have certain deformability, to realize the crimp of positioning convex point and conjunction plane, in the middle of preferentially adopting, protruding pinna is provided with the structure of grooving 312.
The lower end of rotation coupling block 30 is provided with connection holes 32, and the upper end of fixed arm inner casing 2212 is provided with the lug boss 23 that penetrates in connection holes 32.Lug boss 23 comprises the connection neck 231 that cooperates with connection holes 32 and the connection stopper section 232 that places connection holes 32 inboards; The center of lug boss 23 is provided with axial groove 233.Also comprise the latch fitting 80 that places in the axial groove 233, latch fitting 80 comprises latch fitting head 81 and latch fitting insertion section 82, and latch fitting insertion section 82 is inserted in the axial groove 233.Rotation coupling block 30 also is provided with the enclosing cover 33 that clamp-close type connects.Wherein, axial groove 233 can extend to the part in upper end of fixed arm inner casing 2212 own, to improve the deformability of lug boss.The ear casing assembly with the assembling process of rotation coupling block is: with certain pressure with fixed arm inner casing upper end lug boss be inserted in the connection holes that rotates in the coupling block, latch fitting is inserted in the axial groove of lug boss again, again enclosing cover is covered.Wherein, the thickness of latch fitting insertion section is slightly larger than the width of axial groove, to realize closely cooperating between the two.
In order to prevent that the rotation between ear casing assembly and the rotation coupling block from surpassing 360 degree (because also have the audio frequency tie between the two, if energy continuous rotation, be easy to damage the audio frequency tie), be provided with anti-rotation stops 234 at connection neck 231, also be provided with corresponding projection (not shown) on the connection holes 32.Ear casing assembly and the rotation of rotation between the coupling block again can so that the user when wearing, ear casing is regulated along with the tapering of user's head carries out self adaptation, has improved the comfortableness of wearing.
Because the use state that the ear casing assembly is being opened fully, during with receiving state after folding, the state of itself suffers restraints, and is difficult for rotating, therefore, ear casing assembly and the rotary location that does not need to consider direction of rotation that is actively coupled that rotates coupling block.
In other embodiment, the rotation coupling block also can adopt opposite structure with the hinge-coupled of headband, is about to protruding pinna and is located at the end of headband, and be provided with the flute profile lug boss in the upper end of ear casing assembly.
In other embodiment, the rotation coupling block also can adopt opposite structure with the salient point groove location structure of headband, and namely the open slot dual-side of flute profile lug boss is established and had plenty of detent, and the both sides of protruding pinna are established and had plenty of positioning convex point.
In other embodiment, link arm can adopt monolithic construction, and its length can not change.
In other embodiment, the length of rotation coupling block can be adjusted accordingly according to the needs of folding space, thereby makes the Headphone structure of difformity, different size reach different folding effects.
In sum, the utility model is by hinge-coupled and the rotary movable linkage structure of rotation coupling block, can realize that ear casing assembly 90-degree rotation is afterwards again to the headband folded inside, so that two ear casing assemblies are after 90-degree rotation, stagger mutually in the position, realized maximum folding effect, reduce widely the folding size afterwards of earphone, and be provided with the location structure of salient point groove in the connection place of rotation coupling block and headband, help the location of earphone when opening with folded state, conveniently use and carry.Rotate the simple in structure of coupling block, assembling is easy, and production cost is low, and this critical piece of link arm has been adopted split-type structural, the structure of the built-in steel band of travelling arm shell that travelling arm employing plastic cement is wherein made had both guaranteed structural strength, had reduced again production cost; And assembling is simple.Owing to be the rotary mode that is actively coupled between ear casing and the headband, so, be applied to when upper, ear casing can be regulated automatically along with different users's head tapering the angle of ear casing, make itself and human body ear properer, also do not have the sensation of pressing ear, promoted the comfortableness of wearing.
Above-mentionedly only further specify technology contents of the present utility model with embodiment; so that the reader is more readily understood; but do not represent execution mode of the present utility model and only limit to this, any technology of doing according to the utility model is extended or recreation, all is subjected to protection of the present utility model.Protection range of the present utility model is as the criterion with claims.
