[0002] Headphones are widely used in people's lives as an audio output device to improve the convenience and portability of various audio, video and call equipment. At present, the headphones on the market have a connecting arm, mounting arms arranged at both ends of the connecting arm, an earphone body arranged on the mounting arm, and a wire connecting the two earphone bodies along the connecting arm. In order to improve wearing comfort, the length of the connecting arm of conventional headphones is mostly adjustable. In the process of adjusting the connecting arm, the wire also needs to move inside the connecting arm. Therefore, a larger moving space is required, resulting in a very large size of the sliding arm, which is not beautiful and is easy to cause the wire to be tangled and worn, affecting the use of the headphones. Summary of the invention

[0003] The purpose of the present invention is to provide a headset stand to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] A headphone stand comprises: a connecting arm, on which a first wire clamping structure is provided, the first wire clamping structure has an inlet wire channel and a transfer space; an adjusting arm, on which a second wire clamping structure is provided, the second wire clamping structure extends in a direction close to the first wire clamping structure, the second wire clamping structure has an outlet wire channel, the transfer space is connected to the inlet wire channel and the outlet wire channel respectively, and the second wire clamping structure is slidably connected to the first wire clamping structure; and a stopping structure, which can fix the connecting arm and the adjusting arm relatively.

[0006] This technical solution has at least the following beneficial effects: adjusting arms are slidably provided at both ends of the connecting arm, and mounting arms are provided on the adjusting arms. During use, the position of the second wire clamping structure on the first wire clamping structure is adjusted so that the adjusting arm and the connecting arm slide relative to each other, and the stopping structure clamps the adjusting arm on the connecting arm to adjust the length of the headphone holder. Moreover, when adjusting the length of the headphone holder, the wire extends in sequence along the connecting arm, the wire inlet channel of the first wire clamping structure, the transfer space, the wire outlet channel of the second wire clamping structure, the adjusting arm, and the mounting arm, and the wire inlet channel and the wire outlet channel are clamped thereon. The extended wire part, the wire input channel and the wire output channel both have a wire input end and a wire output end, and the transfer space connects the wire output end of the wire input channel and the wire input end of the wire output channel. When in use, the adjusting arm is pulled out, and the second wire clamping structure gradually slides out of the first wire clamping structure. The wire moves with the second wire clamping structure, and the part of the wire located in the transfer space gradually moves out with the wire output channel, reducing the knotting and wear of the wire. After use, the second wire clamping structure is stored on the first wire clamping structure, and the transfer space can store enough wires to ensure the position adjustment of the adjusting arm, thereby reducing space occupancy and improving user experience.

[0007] As a further improvement of the above technical solution, the top surface of the first wire clamping structure is provided with a lead groove, a rotary groove, and a accommodating groove horizontal to the lead groove in sequence along the direction away from the connecting arm, the lead groove and the rotary groove are connected to each other to form the incoming wire channel, the rotary groove is semicircular, the top surface of the second wire clamping structure is provided with a wiring groove, the wiring groove forms the outgoing wire channel, the second wire clamping structure is slidably connected to the accommodating groove, the transfer space and the accommodating groove are respectively located on both sides of the lead groove, and the transfer space is respectively connected to one end of the rotary groove away from the wiring groove and one end of the wiring groove close to the connecting arm. The transfer space and the accommodating groove are respectively arranged on both sides of the lead groove, and the wire is fixed on the lead groove and the rotating groove in turn. Then, after the wire extends out of the rotating groove, it enters the transfer space in the direction opposite to the extension direction of the lead groove. Then, the wire passes over the lead groove in the vertical direction and is fixed in the wiring groove. When the second wire clamping structure slides along the accommodating groove, the part of the wire in the wiring groove moves with the second wire clamping structure, while the part of the wire in the transfer space spans the lead groove and moves, saving setting space. At the same time, the method of rotating and winding the wire is adopted, which not only provides sufficient activity area for the wire and reduces the torsional wear of the wire, but also the retained wire provides a basis for the position adjustment of the adjusting arm, reducing the adjustment jamming phenomenon caused by insufficient wire length. When in use, the adjusting arm is pulled out, and the second wire clamping structure gradually withdraws from the first wire clamping structure. After use, the second wire clamping structure is stored on the first wire clamping structure to reduce space occupancy.

The rack is arranged on the adjustment arm, and the sliding direction of the adjustment arm is horizontal to the extension direction of the rack. One end of the spring sheet is arranged on the first clamping structure, and the other end of the spring sheet can extend into any tooth groove on the rack. The adjustment arm is slidably connected to the first clamping structure, so that the adjustment arm can slide relative to the connecting arm. The adjustment arm is provided with a rack, and as the adjustment arm slides, the other end of the spring sheet arranged on the first clamping structure slides along the rack and can be pressed into the adjacent closest tooth groove, so as to realize the rapid positioning of the adjustment arm and the first clamping structure, and the structure is reliable, convenient and fast.

[0011] As a further improvement of the above technical solution, the adjusting arm is sleeved on the first wire clamping structure, the first wire clamping structure also includes a cover plate, the cover plate covers the incoming wire channel, the transfer space and the outgoing wire channel, and the adjusting arm is slidably connected to the cover plate. The cover plate covers the incoming wire channel, the transfer space and the outgoing wire channel, which facilitates the installation of the wire body, and plays a role in dust prevention and preventing the wire body from falling off, and the adjusting arm is slidably connected to the cover plate, so that the adjusting arm and the first wire clamping structure can slide relative to each other, and the structure is reliable.

[0012] As another improvement of the above technical solution, the present invention also includes a mounting arm and an adapter, wherein the adapter is arranged at one end of the adjustment arm away from the connecting arm, the end face of the adapter is provided with a mounting through hole, the mounting through hole is connected to the outlet channel, the peripheral wall of the adapter is provided with a slide groove, the mounting arm is sleeved on the adapter, the mounting arm is provided with a positioning block, the positioning block extends into the slide groove and can slide along the slide groove.

Moreover, the wire directly passes through the second clamping structure through the mounting through hole and is connected to the earphone body of the mounting arm, so that the user can prevent the wire from twisting and getting stuck during the adjustment process.

[0013] As a further improvement of the above technical solution, the mounting arm includes a connecting part and a mounting part detachably connected to the connecting part, the connecting part is provided with a connecting through hole, the adapter is located in the connecting through hole, the side of the connecting part is provided with a positioning hole, the positioning hole is tangent to the connecting through hole and is connected to the slide slot, the positioning block is arranged in the positioning hole, the mounting part is relatively fixed to the connecting part, and the mounting part covers the positioning hole.

Specifically, when in use, the adjustment arm 130 is pulled out, and the second wire clamping structure 140 gradually withdraws from the first wire clamping structure 120, and the wire 100 moves with the outlet channel 220, and always moves in the transfer space 123, so as to ensure that the movement trajectory of the wire 100 is fixed, and reduce the knotting and wear of the wire 100. After use, the second wire clamping structure 140 is stored on the first wire clamping structure 120, and the transfer space 123 can store enough wires 100 to ensure the position adjustment of the adjustment arm 130, thereby reducing space occupation and improving the user experience. It should be noted that the inlet channel 210 and the outlet channel 220 surround the two sides of the wire body, and the side walls of the inlet channel 210 and the side walls of the outlet channel 220 can each be provided with a plurality of convex particles at intervals along the extension direction thereof, so as to realize the clamping and positioning of the wire body, facilitate disassembly and assembly, and have a simple structure.

[0030] Moreover, in some embodiments, the top surface of the first wire clamping structure 120 is provided with a lead groove 121, a rotary groove 122, and a receiving groove horizontal to the lead groove 121 in sequence along the direction away from the connecting arm 110, the lead groove 121 and the rotary groove 122 are connected to each other to form an incoming wire channel 210, the rotary groove 122 is semicircular, and the top surface of the second wire clamping structure 140 is provided with a wiring groove 141, the wiring groove 141 forms an outgoing wire channel 220, the second wire clamping structure 140 is slidably connected to the receiving groove, the transfer space 123 and the receiving groove are respectively located on both sides of the lead groove 121, and the transfer space 123 is respectively connected to one end of the rotary groove 122 away from the wiring groove 141 and one end of the wiring groove 141 close to the connecting arm 110.

At the same time, the method of rotating and winding the wire 100 not only provides sufficient activity area for the wire 100 and reduces torsional wear of the wire 100, but also the remaining wire 100 provides a basis for position adjustment of the adjusting arm 130, reduces the adjustment jamming phenomenon of the adjusting arm 130 caused by insufficient length of the wire 100, and ensures that the movement trajectory of the wire 100 is fixed in the transition space and the accommodating groove.

In addition, the rotation groove 122 extends in the direction away from the wiring groove 141, which is convenient for the installation of the wire 100. In fact, the part of the wire 100 in the transfer space 123 can be crossed from the top or bottom of the lead groove 121 to achieve the avoidance of the wire 100, and the wire 100 has a certain thickness and elasticity, which provides a torsion space for the rotation and winding of the wire 100, and reduces the wear of the wire 100. In actual applications, the openings of the lead groove 121, the receiving groove, the rotation groove 122, the wiring groove 141 and the transfer space 123 are all upward.

[0031] Moreover, in some embodiments, the outlet channel 220 has a height difference with the inlet channel 210. The wire 100 is staggered in height in sections, providing an avoidance effect for the movement of the wire 100 in the outlet channel 220, and reducing the wear of the wire 100.

In this embodiment, the curved wall 160 is located above the lead groove 121, and the lead groove 121 extends upward to the top surface of the curved wall 160, providing an escape space to facilitate the installation of the wire 100 into the lead groove 121.

[0033] Reference Figure 3In order to achieve rapid positioning between the adjustment arm 130 and the connecting arm 110, in some embodiments, the adjustment arm 130 is slidably connected to the first clamping structure 120, and the stop structure includes a rack 320 and a spring 150. The rack 320 is arranged on the adjustment arm 130, and the sliding direction of the adjustment arm 130 is horizontal to the extension direction of the rack 320.

The adjustment arm 130 is slidably connected to the first clamping structure 120, so that the adjustment arm 130 can slide relative to the connecting arm 110. The adjustment arm 130 is provided with a rack 320, and as the adjustment arm 130 slides, the other end of the spring 150 arranged on the first clamping structure 120 slides along the rack 320 and can be pressed into the adjacent closest tooth groove, so as to achieve rapid positioning of the adjustment arm 130 and the first clamping structure 120, and the structure is reliable, convenient and fast. In fact, the spring piece 150 can be threadedly connected to the first clamping structure 120, and the first clamping structure 120 is provided with a positioning column, and the spring piece 150 is hung on the positioning column at the same time, so as to realize the positioning of the threaded connection point and the positioning column, prevent the spring piece 150 from shaking and turning, and improve the installation stability. In addition, the rack 320 has a wavy tooth groove, and the part of the spring piece 150 extending into the tooth groove is also in an arc shape, which is convenient for adjustment and reduces friction.

[0034] Furthermore, in some embodiments, the adjusting arm 130 is sleeved on the first clamping structure 120, and the first clamping structure 120 further includes a cover plate 230, the cover plate 230 covers the incoming line channel 210, the transfer space 123 and the outgoing line channel 220, and the adjusting arm 130 is slidably connected to the cover plate 230. The cover plate 230 covers the incoming line channel 210, the transfer space 123 and the outgoing line channel 220, which is convenient for the installation of the wire body, and at the same time plays a role in dust prevention and preventing the wire body from falling off, and the adjusting arm 130 is slidably connected to the cover plate 230, so that the adjusting arm 130 and the first clamping structure 120 can slide relative to each other, and the structure is reliable.

[0035] In addition, refer to Figure 4 and Figure 5In practical applications, in order to improve the wearing comfort of the headset, a rotating bracket is often inserted between the connecting arm 110 and the mounting arm 410, and then the rotating bracket is fixed with screws. The adjustment structure takes up space, resulting in internal stacking. At the same time, it is necessary to increase the rotating bracket and screws, which has many parts and is troublesome to install. The increased cost also affects the production efficiency. Therefore, in order to solve the above problems, in some embodiments, the present invention also includes a mounting arm 410 and an adapter 310. The adapter 310 is arranged at an end of the adjusting arm 130 away from the connecting arm 110. The end surface of the adapter 310 is provided with a mounting through hole 311, and the mounting through hole 311 is connected to the outlet channel 220. The peripheral wall of the adapter 310 is provided with a slide groove 510. The mounting arm 410 is sleeved on the adapter 310. A positioning block 520 is provided on the mounting arm 410. The positioning block 520 extends into the slide groove 510 and can slide along the slide groove 510. Moreover, in this embodiment, the peripheral wall of the adapter 310 is covered with an anti-skid ring 540, and the outer wall of the anti-skid ring 540 abuts against the side wall of the connecting through hole. The mounting arm 410 has an external earphone body, and the mounting arm 410 is covered on the adapter 310. The peripheral wall of the adapter 310 is provided with a slide groove 510. The positioning block 520 of the mounting arm 410 slides along the slide groove 510 relative to the adapter 310 in the circumferential direction, so that the mounting arm 410 can rotate relative to the connector. When the mounting arm 410 rotates relative to the adapter 310, the anti-skid ring 540 increases the rotation resistance of the mounting arm 410. When the user wears the earphone, the mounting arm 410 can slide around the anti-skid ring 540. , and the earphone body is automatically adapted to the user's ear under the action of the mounting arm 410 while maintaining the position, which is convenient for adjustment without the need for additional positioning parts. The rotation axis of the mounting arm 410 coincides with the central axis of the adapter 310, which facilitates the adjustment of the angle of the earphone body, so that the earphone body fits the user's ear and improves the wearing comfort. Moreover, the wire 100 directly passes through the second wire clamping structure 140 through the mounting through hole 311 and is connected to the earphone body of the mounting arm 410. During the adjustment process, the user can prevent the wire 100 from being twisted or stuck.

[0036] Moreover, in the present embodiment, the mounting arm 410 includes a connecting portion 411 and a mounting portion 412 detachably connected to the connecting portion 411; a connecting through hole is provided on the connecting portion 411; the adapter 310 is located in the connecting through hole; a positioning hole 530 is provided on the side of the connecting portion 411; the positioning hole 530 is tangent to the connecting through hole and is connected to the slide groove 510; the positioning block 520 is disposed in the positioning hole 530; the mounting portion 412 is relatively fixed to the connecting portion 411; and the mounting portion 412 covers the positioning hole 530. During installation, the connecting portion 411 is sleeved on the adapter 310 through the connecting through hole, and the shapes and sizes of the connecting through hole and the adapter 310 match each other. The positioning block 520 is inserted into the positioning hole 530 from the side of the connecting portion 411. Through the position positioning function of the positioning hole 530, the extension direction of the positioning block 520 is tangent to the slide groove 510, and the positioning block 520 extends into the slide groove 510 to achieve relative sliding. Then, the mounting portion 412 is connected and installed on the positioning block 520, and at the same time covers the positioning hole 530 to prevent the positioning block 520 from falling out. There are few parts, a reliable structure, reduced internal stacking, reduced space occupation, convenient installation, and improved production efficiency. In fact, the positioning block 520 can be a columnar structure such as a pin or other structure, as long as it will not fall out of the slide groove 510 and the positioning hole 530.

[0037] In addition, refer to Figure 6 and Figure 7 , the rotation angle α of the slide groove 510 along the adapter 310 satisfies: 90°<α<135°, and the slide groove 510 extends from the top of the swivel joint 310. The rotation angle is greater than 90°, which facilitates the storage and deployment of the mounting arm 410, conforms to ergonomics, improves the wearing comfort of the headset, and prevents the mounting arm 410 from rotating too much. In fact, the rotation angle α of the slide groove 510 is 125°.
