Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a novel rotatable and adjustable ear hook component. Background Art

[0002] An earhook earphone is an earphone with an auxiliary hanging earhook added to the side of the earphone for easy use. The earhook wireless earphone includes an earhook and an earphone housing. The earphone housing is connected to the lower end of the earhook, and a speaker is installed inside the earphone housing. In the prior art, the earhook of an earhook earphone often cannot be adjusted by rotating, making it difficult to match the ears of different users and difficult to adjust to the most comfortable wearing effect.

[0003] With the advancement of technology, headphones with new rotatable and adjustable ear hook components have gradually appeared. Refer to Chinese patent document CN 218634221 U, which discloses a rotating ear hook structure, including an ear hook unit, and an active connection sleeve rotatably connected to the ear hook unit; one end of the ear hook unit is provided with a first inclined portion extending obliquely in a preset rotation direction, and the active connection sleeve is provided with a second inclined portion cooperating with the first inclined portion; the active connection sleeve is connected to a spring for driving the active connection sleeve to move in a direction close to the ear hook unit. External force drives the ear hook unit to rotate along the preset rotation direction to adjust the wearing angle of the ear hook unit; when the ear hook unit is not subjected to external force, the active connection sleeve will move in a direction close to the ear hook unit under the action of the spring, realizing the automatic reset function after the ear hook is rotated. The rotating ear hook structure also includes a sleeve, and the movable connection sleeve can be slidably mounted in the sleeve; a first limiting boss is arranged in the sleeve, and the movable connection sleeve slides along the sleeve to a preset position, and the movable connection sleeve abuts against the first limiting boss, and a first limiting space is formed between the first limiting boss and the upper end opening of the sleeve, so that the movable connection sleeve can slide up and down along the first limiting space, and a second limiting boss is arranged at one end of the sleeve away from the ear hook unit, and two ends of the spring are respectively connected to the movable connection sleeve and the second limiting boss, and a protective sleeve is arranged at one end surface of the protective sleeve. A receiving groove is provided; the second limiting boss A through hole is formed in the middle of the platform, and one end of the connecting shaft passes through the through hole and is accommodated in the accommodating groove. The function of the protective sleeve is that when assembling the earphone, the sleeve needs to be glued and fixed to the earphone body. In order to prevent the glue from overflowing into the sleeve, this scheme provides a protective sleeve at the end of the sleeve close to the earphone body. The protective sleeve accommodates the connecting shaft in the accommodating groove, thereby separating the inner space of the sleeve from the gluing installation surface, thereby protecting the movable connecting sleeve and the elastic member; an annular groove is provided at the insertion end of the connecting shaft, and an isolation sleeve is installed in the annular groove; the isolation sleeve is accommodated in the accommodating groove, and the diameter of the isolation sleeve is larger than the diameter of the through hole.

[0004] However, the rotating ear hook structure disclosed in the above-mentioned Chinese patent document CN 218634221 U has the following defects: (1) Although the ear hook has a rotating function and can realize the automatic reset function after the ear hook is rotated under the cooperation of the movable connecting sleeve and the spring, the ear hook has no damping effect during the rotation process and cannot maintain a certain adjusted angle, which is not suitable for most headphone users; (2) When assembling the headphone, the sleeve needs to be fixed to the headphone body with glue, which is cumbersome to assemble and has poor stability; (3) A protective cover needs to be provided at the end of the sleeve close to the headphone body, and a movable connecting sleeve and a spring need to be provided inside the sleeve, which increases the cost of parts and assembly costs.

The "O" ring structure has an interference fit with the upper end inner cavity wall of the bracket cavity 501, and the friction force serves as the damping of the ear hook rotation.

[0030] When assembling the present invention, first, the ear hook shaft 2 is inserted into the fixed sleeve 3 from top to bottom. During the insertion process, the lower end of the ear hook shaft 2 pushes outward to open the elastic clamping claw 301, and the clamping claw buckling portion 303 buckles into the annular groove 201 to achieve limiting, preventing the ear hook shaft 2 from loosening upward from the fixed sleeve 3, and the elastic clamping claw 301 elastically resets inward; then, the fixed sleeve 3 and the ear hook shaft 2 are inserted into the bracket cavity 501 of the rotating bracket 5 together, and the sleeve buckling portion and the cavity buckling portion are buckled and fixed to each other, which is easy to assemble, and there is no need to fix the fixed sleeve with glue. The buckling fixing method has good stability; after the fixed sleeve 3 is assembled with the bracket cavity 501, the damping portion 101 of the ear hook 1 is located in the upper end of the bracket cavity 501 to achieve rotational damping cooperation, so that the new rotatable and adjustable ear hook component of the present invention has a rotational damping effect and can maintain the adjusted angle to suit most headphone users. The utility model realizes the rotation of the ear hook of the earphone through the ear hook, the ear hook rotating shaft, the fixing sleeve and the rotating bracket, and has fewer overall parts, and the parts cost and the assembly cost are low.

[0031] like Figure 3-Figure 5 As shown, the lower end of the ear hook shaft 2 is provided with a conical plug 202, the annular groove 201 is located on the upper side of the conical plug 202, the lower groove surface of the annular groove 201 is a plane, and the upper groove surface of the annular groove 201 is an inclined surface; the number of the elastic clamping claws 301 is four, the lower side surface of the clamping claw buckling part 303 is a plane, and the upper side surface of the clamping claw buckling part 303 is an inclined surface. When the ear hook shaft 2 is inserted downward into the fixing sleeve 3, the outer side surface of the conical plug 202 is an inclined surface, which can match the upper side surface of the clamping claw buckling part 303 to gradually push open the elastic clamping claw 301; after the clamping claw buckling part 303 is buckled into the annular groove 201, the upper side surface of the clamping claw buckling part 303 is an inclined surface, which can match the upper groove surface of the annular groove.

[0032] like Figure 3-Figure 5 As shown, the upper end of the ear hook shaft 2 is provided with a plurality of outwardly protruding ribs 203 and a plurality of connecting holes 204, and one end of the ear hook 1 is integrally formed with the upper end of the ear hook shaft 2 by in-mold injection molding. During in-mold injection molding, the material of the ear hook 1 is integrated into the gaps between the ribs and the connecting holes, so that the ear hook 1 and the ear hook shaft 2 are tightly connected.

[0033] like Figure 3-Figure 6As shown, the cavity buckling part includes a positioning slot 502 arranged on the inner wall of the bracket cavity 501, and the sleeve buckling part includes an elastic arm 304 connected to the upper end of the fixed sleeve 3 and extending upward, and a positioning block 305 protruding from the outer side of the upper end of the elastic arm 304, and an elastic arm gap 306 is provided between the elastic arm 304 and the fixed sleeve 3. When the fixed sleeve 3 is inserted into the bracket cavity 501 from top to bottom, the bracket cavity 501 can squeeze the positioning block 305, so that the upper end of the elastic arm 304 elastically deforms inward and compresses the elastic arm gap 306 until the positioning block 305 is buckled into the positioning slot 502, and the positioning block 305 is buckled and fixed with the positioning slot 502, and the upper end of the elastic arm 304 is elastically reset outward; one side of the ear hook shaft 2 is provided with an avoidance position 205 for avoiding the elastic deformation of the upper end of the elastic arm 304 inward. After the positioning block 305 is buckled into the positioning slot 502 , the upper side surface of the positioning block 305 abuts against the upper groove surface of the positioning slot 502 , which can prevent the positioning block 305 from moving upward.

[0034] like Figure 3-Figure 6 As shown, the inner wall of the bracket cavity 501 is also provided with a vertical guide clip 503, and the guide clip 503 is inserted into one of the jaw gaps 302 of the fixed sleeve 3. By providing the guide clip 503, on the one hand, it can play a guiding role when the fixed sleeve 3 is inserted into the bracket cavity 501 from top to bottom, and on the other hand, it can prevent the fixed sleeve 3 from rotating in the bracket cavity 501.

[0035] like Figure 3-Figure 5 As shown, the upper end height of the elastic arm 304 is higher than the upper end height of the fixed sleeve 3, and the upper end of the ear hook shaft 2 has a shaft limiter 206 protruding outward, and the lower end surface of the shaft limiter 206 abuts against the upper end surface of the fixed sleeve 3 to prevent the ear hook shaft 2 from loosening downward from the fixed sleeve 3. The side walls of the shaft limiter 206 are limited and matched with the side walls of the elastic arm 304. When the ear hook shaft 2 rotates clockwise or counterclockwise, the side walls of the elastic arm 304 can limit the rotation end position of the shaft limiter 206. Figure 2 As shown, through the limiting cooperation between the elastic arm 304 and the rotation axis limiting portion 206, the maximum rotation angle of the ear hook 1 is: the maximum clockwise rotation is 20 degrees, and the maximum counterclockwise rotation is 90 degrees. The width of the elastic arm 304 and the rotation axis limiting portion 206 can be adjusted according to the actual rotation angle. The rotation limiting structure is set above the fixed sleeve 3, the torsional strength is increased, and a lower strength material can be used to achieve the required strength to reduce the cost; all parts can be injection molded with plastic materials when the reliability requirements are met, which is the most cost-effective.

[0036] As a preferred embodiment of the present invention, the ear hook 1 is made of wear-resistant TPU material or silicone material, and the fixing sleeve 3 is made of high-strength plastic. The ear hook shaft 2 and the rotating bracket 5 are made of metal material by casting or powder metallurgy process, or made of high-strength plastic by injection molding process.

[0037] like Figure 7-Figure 11As shown, the novel rotatable and adjustable ear hook assembly further comprises an earphone housing 6, a first gasket 7, an elastic damping member 8 and a connecting member 9, a turntable cavity 603 is provided on the outer side of the earphone housing 6, the elastic damping member 8 is installed in the turntable cavity 603, a cavity through hole 6031 is provided in the middle of the turntable cavity 603, a gasket groove 604 is provided on the inner side of the earphone housing 6, the first gasket 7 is rotatably installed in the gasket groove 604, and a plug-in hole 701 is provided in the middle of the first gasket 7; the other end of the rotating bracket 5 is provided with The rotating disk 505 is rotatably installed in the turntable cavity 603. A rotating column 506 is provided in the middle of the side of the rotating disk 505 facing the earphone housing 6. The rotating column 506 can rotatably pass through the cavity through hole 6031. The end of the rotating column 506 is plugged and fixed in the plug hole 701 of the first gasket 7. The connecting member 9 passes through the first gasket 7 and connects to the rotating column 506, so that the first gasket 7 and the rotating column 506 are fixed to each other; the rotating disk 505 cooperates with the elastic damping member 8 for rotational damping. The rotating disk of the rotating bracket of the utility model can rotate in the turntable cavity of the earphone housing, and the rotatable connection between the rotating bracket and the earphone housing is realized by connecting the rotating column to the first gasket and the first gasket rotating in the gasket groove, which can avoid the problem of poor connection caused by severe wear. The first gasket 7 of the utility model is plugged and fixed with the end of the rotating column 506 through the plug hole 701, so that the first gasket 7 can be linked with the rotating disk 505 of the rotating bracket 5. When rotating, the rotating bracket 5, the first gasket 7, and the connecting member 9 will not have relative rotation displacement, which can avoid the problem of the connecting member and the first gasket being loosened due to rotation. In addition, the contact surface of the gasket groove 604 of the earphone housing 6 and the first gasket 7 are both smooth surfaces, and the degree of wear during the life cycle of the earphone will not affect the normal use of the new rotatable and adjustable ear hook assembly. The utility model uses the elastic force of the elastic damping member 8 and forms a rotation damping through the friction between the rotating disk 505 and the elastic damping member 8, so that the ear hook 1 can maintain the adjusted angle after the rotating disk 505 of the rotating bracket 5 rotates to a certain angle. The rotating disk of the rotating bracket of the utility model can rotate within the turntable cavity of the earphone shell, and the rotating bracket and the earphone shell are rotatably connected in a manner that the first gasket is connected by a rotating column and the first gasket rotates within the gasket groove, thereby avoiding the problem of poor connection caused by severe wear; the utility model installs the first gasket and the connecting piece from the inside of the earphone shell, and there is no need to open holes and embed parts on the back of the rotating bracket, so that the external integrity of the ear hook assembly is good.

[0038] like Figure 8 and Fig.10As shown, the plug hole 701 is a non-circular chamfered hole or a polygonal hole or a special-shaped hole, and the end of the rotating column 506 is provided with a plug connector 5061 matching the shape of the plug hole 701, and the plug connector 5061 is plugged into the non-circular chamfered hole or the polygonal hole or the special-shaped hole. Since the plug hole 701 is a non-circular chamfered hole or a polygonal hole or a special-shaped hole, after the plug connector 5061 of the rotating column 506 is inserted into the plug hole 701 of the first gasket 7, the rotating column 506 can be fixedly linked with the first gasket 7 without relative rotation displacement.

[0039] like Figure 8-Figure 11 As shown, a screw hole 5062 is provided in the rotating column 506, and the connecting member 9 is a screw, one end of which passes through the insertion hole of the first gasket 7 and is screwed into the screw hole 5062. After the screw is screwed into the rotating column 506, the rotating bracket 5, the first gasket 7, and the screw are fixed together without relative rotation displacement.

[0040] like Figure 8-Figure 11 As shown, an elastic damping member positioning block 605 is provided in the rotating disk cavity 603, and an elastic damping member positioning groove 6051 is provided in the elastic damping member positioning block 605, and the elastic damping member 8 is installed in the elastic damping member positioning groove 6051. The elastic damping member 8 is a spring steel ball, and a plurality of arc-shaped continuously arranged pits 507 are provided on the side of the rotating disk 505 facing the earphone housing 6, and the spring steel ball elastically abuts against any of the pits 507. When the rotating disk 505 rotates, the spring steel ball can elastically fall into different pits 507, and the shape of the pit 507 is preferably an arc surface matching the surface of the spring steel ball. When the spring steel ball falls into a certain pit 507, the spring steel ball can abut against the pit 507 to achieve the positioning of the earphone housing 6 and the rotating bracket 5; when the angle between the earphone housing 6 and the rotating bracket 5 needs to be adjusted, the rotating bracket 5 needs to be rotated with force to make the spring steel ball elastically compressed, disengaged from the abutment with a certain pit 507, and then fall into another pit 507 to achieve the positioning of the earphone housing 6 and the rotating bracket 5 again. As a preferred embodiment of the spring steel ball, the spring steel ball includes a spring sleeve, a spring and a steel ball, one end of the spring sleeve has an opening, the spring is installed in the spring sleeve, and the steel ball is connected to the spring and movably installed at the opening of the spring sleeve.

[0041] like Figure 8 and Fig. 9As shown, the first limit stopper 5081 and the second limit stopper 5082 are provided on the side of the rotating disk 505 facing the earphone housing 6, and the plurality of the pits 507 are located in the area between the first limit stopper 5081 and the second limit stopper 5082. The elastic damping member positioning block 605 and the spring steel ball extend into the area between the first limit stopper 5081 and the second limit stopper 5082. When the rotating disk 505 rotates, the first limit stopper 5081 and the second limit stopper 5082 can cooperate with the two sides of the elastic damping member positioning block 605 to limit the rotation angle of the rotating disk 505. Figure 7 As shown, through the limiting action of the first limiting block 5081 and the second limiting block 5082, the maximum rotation angle of the rotating disk 505 of the rotating bracket 5 is: a maximum clockwise rotation of 30 degrees, and a maximum counterclockwise rotation of 30 degrees.

[0042] like Figure 8-Figure 11 As shown, the novel rotatable and adjustable ear hook assembly further includes a second gasket 10, which is installed at the bottom of the turntable cavity 603, and is provided with a gasket through hole 1001, one end of which corresponds to and matches the cavity through hole 6031, and the other end of which is sleeved outside the elastic damping member positioning block 605; the side of the rotating disk 505 facing the earphone housing 6 is in contact with the second gasket 10. Generally, the external force that pushes the rotating bracket 5 to rotate is not always in an ideal state, and there will be forces in all directions. The edge of the rotating disk 505 of the rotating bracket 5 and the matching surface of the earphone housing 6 will be locally subjected to greater pressure, which may cause serious wear. In this design, a second gasket 10 is provided between the two, which can prevent the problem of serious wear of the edge of the rotating disk 505 of the rotating bracket 5 and the matching surface of the earphone housing 6. Preferably, the second gasket 10 is a UPE ultra-high molecular weight polyethylene gasket, which can best solve this wear problem by relying on its excellent wear resistance and self-lubricating properties.
