The present invention relates to a ear stand device for an earphone, and more particularly to a head stand device.

With the increasing popularity of portable electronic products such as smart phones, tablets, PDAs, people listening to music or watching movies in public places such as MRT cars and restaurants have become a sight everywhere in everyday life. In order to maintain high-quality sound effects in the above-mentioned noisy public places, many people use earmuff-type headphones to isolate external noise.

Although the earmuff type earphone has good sound insulation effect, the volume of the ear frame device is relatively large, which often causes the user to be troubled during storage. Therefore, in order to improve the convenience of earphone type headphone storage, some manufacturers have developed earphones with a folding ear holder device, so as to reduce the volume of the earphone storage.

However, in the prior art, the earphone with the folding ear frame device has to reserve space or dig a gap on other components in order to make the movable component not interfere with other components during the movement, so as to provide the movable component as an activity. Space. However, the above-mentioned reserved space or the method of severing the gap will destroy the integrity of the ear frame device, which will not only reduce the overall structural strength, but also The connection between the movable element and other components forms a discontinuous or uneven discontinuous plane, which makes the joint connection of the component impossible to be integrated, resulting in a significant reduction in aesthetics and texture.

In addition, although the existing folding ear frame device has a gap for the movable element to be moved in advance, the movable range of the movable element is still limited by the limitation of the size of the gap, and will still be combined with other operations for a large range of motion. The components interfere with each other and the ear holder device cannot be completely folded and stored. Therefore, the existing folding ear frame device obviously has room for improvement.

Accordingly, it is an object of the present invention to provide a storable ear holder device that is rotatably received without damaging the structural integrity.

The first telescopic portion and the second telescopic portion are respectively restrained from each other and can only move relative to each other in the telescopic direction, so that the mounting brackets can only be moved along the telescopic direction between a retracted position near the headband and a stretched position away from the headband. Complex exercise.

The two suspension units are pivotable relative to the corresponding mounting seat about a pivoting position through the two mounting seats between a stowed position inside the headband and a position away from the headgear.

Preferably, when the mounting seats are in the retracted position and the corresponding hanging unit is in the use position, the inner side of the hanging unit is adjacent to the inner side surface of the headband, and the joints are substantially continuous.

Preferably, each suspension unit is pivotable at an angle greater than or equal to 180 degrees with respect to the corresponding mount.

Preferably, the accommodating ear holder device further comprises two pivoting mechanisms respectively connecting the hanging unit and the corresponding mounting seat. Each pivoting mechanism includes a pivoting member that passes through the hanging unit from the inside of the corresponding hanging unit and is fixed to the mounting seat along the pivot. The pivoting member cooperates with the corresponding mounting seat, so that the hanging unit is clamped in the direction of the pivot, and can pivot pivotally.

Preferably, each pivoting mechanism further includes a shaft hole formed on an inner side surface of each mounting seat, and a shaft post protruding from the corresponding hanging unit toward the shaft hole. Each of the shaft columns is cylindrical and the threading limit is located in the corresponding shaft hole.

Preferably, each of the shaft columns has a ring-shaped annular wall. The pivoting mechanism further includes an elastic member fixed to the mounting seat and partially extending into the shaft hole. Each of the elastic members has a top abutting portion that abuts against the corresponding ring wall.

Preferably, the elastic member is integrally formed with the corresponding mounting seat.

The foregoing and other technical aspects, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to FIG. 1 to FIG. 4 , the present invention can include a headband 1 having an arc shape, two mounting brackets 2 at opposite ends of the headband 1, and two mounting brackets 2 and a headband 1 respectively. The telescopic mechanism 3 and the two are respectively pivotally connected to the hanging unit 4 inside the two mounting bases 2, and two pivoting mechanisms 5 respectively connecting the hanging unit 4 and the corresponding mounting base 2. The headband 1 is for the user to wear on the head. Each of the mounts 2 extends downward from a corresponding end of the headband 1 in a telescopic direction D. Each of the telescopic mechanisms 3 includes a first telescoping portion 31 disposed at one end of the headband 1 and a second telescoping portion 32 disposed at one end of the corresponding mounting bracket 2 adjacent to the headband 1. The first telescopic portion 31 and the second telescopic portion 32 are mutually constrained and can only move relative to each other along the telescopic direction D, so that the mounting brackets 2 can only be in the retracted position of the headband 1 along the telescopic direction D (as shown in the figure). 2) Reciprocating motion with a stretched position away from the headband 1 (Fig. 4). In this comparison In a preferred embodiment, each of the first telescopic portions 31 is a chute formed at both ends of the headband 1; each of the second telescoping portions 32 extends from the corresponding mounting seat 2 toward the headband 1 and the through-limit is located in the corresponding chute. Slide. However, in practical applications, the first telescopic portion 31 and the second telescopic portion 32 are not limited to the chute and the slide, and only need to be able to be restrained from each other and only move relative to each other along the telescopic direction D.

Referring to FIGS. 3-6, each pivoting mechanism 5 includes a pivoting member 51. Each pivoting member 51 passes through the hanging unit 4 from the inner side of the corresponding hanging unit 4 along a pivot X passing through the two mounting bases 2, and is fixed to the corresponding mounting seat 2 to cooperate with the mounting seat 2 to make the hanging unit 4 The clamping position is clamped in the direction of the pivot X, and the two hanging units 4 can be pivoted with respect to the corresponding mounting seat 2 with the pivot axis X as a center inside the headband 1 (as shown in FIG. 5 Figure 6) pivots with a position away from the headband 1 (as in Figures 3 and 4). Wherein, when each of the mounting bases 2 is in the retracted position and the corresponding hanging unit 4 is in the use position, the inner side surface of the hanging unit 4 is adjacent to the inner side surface of the headband 1, and the joints thereof are in a continuous plane ( Referring to Fig. 2), therefore, the abutment of the suspension unit 4 and the headband 1 maintains the structural integrity and continuity, and can be used for various continuous design designs.

When the storage device for storing the ear holder of the present invention is stored, the mounting base 2 is first stretched from the retracted position to the extended position by the telescopic mechanism 3, whereby the suspension unit 4 and the headband 1 are stretched. The abutting portions are separated from each other to generate an active space for the hanging unit 4 to rotate; then the hanging unit 4 is rotated, and the hanging unit 4 is rotated from the use position by the pivot X to the storage position, so that the hanging unit 4 is Partially overlapping the inner side of the headband 1, the overall volume of the earhook device can be reduced for storage. Among them, the use of telescopic The mechanism 3 keeps the hanging unit 4 away from the design of the headband 1 when it is to be stored, and maintains the integrity of the connection between the hanging unit 4 and the headband 1 before storage, and also makes the hanging unit 4 completely closed during storage. It does not interfere with the headband 1 and other components, and the rotation angle of the suspension unit 4 is not limited by the blocking of the headband 1. In addition, after the suspension unit 4 is rotated to the storage position, the mount 2 can also be slightly contracted toward the retracted position, further reducing the overall volume of the ear holder device. The headband 1 further includes two cushions 11 respectively disposed on the inner sides of the opposite ends, thereby providing a mechanism for protecting the hanging unit 4 when the hanging unit 4 is in the storage position and the mounting seat 2 is contracted to the retracted position. The hanging unit 4 does not cause collision friction with the inside of the headband 1.

Referring to FIG. 7 to FIG. 9 , each pivoting mechanism 5 further includes a shaft hole 52 formed on an inner side surface of each mounting seat 2 , a shaft post 53 protruding from the corresponding hanging unit 4 toward the shaft hole 52 , and An elastic member 54 integrally formed on the mount 2. Each of the shaft columns 53 is substantially cylindrical and has a toothed ring wall 531 which is disposed in the corresponding shaft hole 52 to be rotatable in the shaft hole 52 as the suspension unit 4 rotates. Each of the elastic members 54 extends into the corresponding shaft hole 52 and has a protrusion abutting against the abutting portion 541 of the ring wall 531 of the shaft post 53. The abutting abutting portion 541 abuts against the toothed ring wall 531, so that the abutting portion 541 can be engaged with each of the recesses of the toothed ring wall 531 when the hanging unit 4 rotates, so that the user has a segment. The hand is adjusted and fixed by the engagement of the abutting portion 541 with the recess of the ring wall 531, so that the hanging unit 4 can be fixed at an arbitrary rotation angle. In the preferred embodiment, the elastic member 54 is a spring piece integrally formed with the mounting seat 2, so that no additional processing procedure for mounting the elastic member 54 on the mounting seat 2 is required, which simplifies the storage of the ear. The complexity of the components of the rack device achieves the effect of improving manufacturing efficiency and reducing costs.

Each of the hanging units 4 forms an arcuate limiting groove 41 with respect to a side of the corresponding mounting seat 2. Each of the mounting bases 2 further includes a limiting block 21 formed by being convex with respect to one side of the hanging unit 4, a plurality of bumps 22 disposed in the corresponding shaft holes 52, and a headband from the outside of the mounting base 2 A baffle 23 extending in one direction. Each of the limiting blocks 21 extends into the corresponding limiting slot 41 and is limited by the limiting slot 41. Therefore, the limiting block 21 can only move relative to the limiting slot 41 within the arc angle range of the limiting slot 41, and the hanging strap is attached. The angle at which the element 4 can rotate relative to the corresponding mount 2 is limited. Each of the bumps 22 has a curved surface 221 that abuts the end of the corresponding shaft post 53, whereby the end of the shaft post 53 is in point contact with the mounting seat 2 in the shaft hole 52 (see FIG. 6), effectively reducing the shaft. The friction between the post 53 and the mount 2 makes the stud 53 more smooth during rotation. The baffle 23 of the mounting seat 2 is spaced apart from the outer side of the corresponding second telescopic portion 32, and can provide an additional protection for the second telescoping portion 32 when the first telescoping portion 31 is stretched, which is not easily damaged by accidental collision. The second expansion and contraction portion 32 is not exposed to the outside of the ear mount device, and the outer shape is affected, so that the overall design is more beautiful.

In this embodiment, the angle of rotation of the hanging unit 4 relative to the mounting seat 2 is approximately equal to 180 degrees, and when the hanging unit 4 is rotated to the opposite limit position points, respectively, the storage position and the use position are respectively It is convenient for the user to switch the hanging unit 4 between the storage position and the use position, and the rotation angle of the hanging unit 4 is not particularly controlled. Of course, the range of relative rotation angles of the hanging unit 4 and the mounting seat 2 can also be changed by changing the arc angle of the limiting slot 41. The degree is changed to an angle greater than 180 degrees, and only the hanging unit 4 can be switched between the storage position and the use position.

In summary, the expansion unit 3 allows the suspension unit 4 to generate an active space during storage, so that the storage of the ear holder device can maintain the integrity of the structure not only during use, but also when the storage unit 4 is stored. The rotation is also completely uninterrupted or limited by other components. In addition, the configuration in which the elastic member 54 is integrally formed on the mount 2 simplifies the component composition and the machining program for accommodating the ear frame device, thereby effectively reducing the manufacturing cost and improving the production efficiency. Therefore, the purpose of this new type can be achieved.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
