DETAILED DESCRIPTION

[0034] The embodiment of the utility model discloses a sliding arm pull-out structure of headphones and headphones, which are used to solve the technical problem in the prior art that when a user pulls the sliding arm to slide it relative to a fixed bracket, the user's operating feel is poor, which affects the user experience.

[0035] To help those skilled in the art better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the embodiments described are only a portion of the present invention, not all of the embodiments. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0036] See also Figures 1 to 6 The embodiment of the present invention provides a headphone sliding arm pulling structure, comprising a fixed bracket 1 and a sliding arm 2. The fixed bracket 1 is provided with a slide groove 5 inside, the sliding arm 2 is slidably arranged in the slide groove 5, and the head end of the sliding arm 2 is exposed in the slide groove 5. The sliding arm 2 can be pulled and slid in the slide groove 5.

[0037] A first damping pad 3 is provided between the starting end of the slide groove 5 and the sliding arm 2, and the first damping pad 3 is sleeved on the outer periphery of the sliding arm 2;

[0038] The sliding arm 2 is sleeved with a second damping pad 4 , and a protrusion 401 is provided on the outer side of the second damping pad 4 . The protrusion 401 abuts against the inner side wall of the sliding groove 5 to form an interference fit.

[0039] It should be noted that the raised portion 401 in this embodiment is specifically arranged around the second damping pad 4, and the cross section of the raised portion 401 can be semicircular, rectangular, etc., which is not limited in this embodiment.

[0040] Through the above design, during the pulling and extending process of the sliding arm 2, the first damping pad 3 is always in contact with the outer wall of the sliding arm 2, and the protrusion 401 on the second damping pad 4 is always in contact with the inner wall of the slide groove 5. The cooperation between the first damping pad 3 and the second damping pad 4 generates damping when the sliding arm 2 slides, so that the user can pull and extend the sliding arm 2 stably, improve the user's operating feel, and facilitate the user to accurately adjust the position of the sliding arm 2, greatly improving the user experience.

[0041] In addition, in this embodiment, the first damping pad 3 not only plays a damping role when the sliding arm 2 slides, but also plays a supporting role, effectively preventing the sliding arm 2 from shaking during the sliding process.

[0042] Furthermore, the protrusion 401 in this embodiment is specifically an annular protrusion, which is arranged around the second damping pad 4 .

[0043] It should be noted that, by designing the protrusion 401 as a ring structure, the protrusion 401 can always rub against the inner side walls of the sliding groove 5 when the sliding arm 2 slides to stably generate damping.

[0044] Furthermore, the fixed bracket 1 in this embodiment includes a sliding upper shell 101 and a sliding lower shell 102;

[0045] The sliding lower shell 102 is provided with a sliding cavity 1021 along its length direction, and the sliding upper shell 101 covers the sliding lower shell 102 to cooperate with the sliding cavity 1021 to form the sliding groove 5.

[0046] It should be noted that the cross-section of the sliding cavity 1021 is similar to a semicircular structure. When the sliding upper housing 101 is covered with the sliding lower housing 102, the sliding upper housing 101 can cover the upper part of the sliding cavity 1021 and form the sliding groove 5 in this embodiment with the sliding cavity 1021. It can be further understood that the specific shapes of the sliding upper housing 101 and the sliding lower housing 102 in this embodiment need to match the shape of the sliding arm 2.

[0047] Furthermore, in order to facilitate the assembly personnel to assemble or disassemble the fixed bracket 1, the sliding upper shell 101 of this embodiment is preferably connected to the sliding lower shell 102 in a detachable manner, specifically by a snap-on connection, a screw-fixed connection, etc., which is not limited in this embodiment.

[0048] Furthermore, a first annular mounting groove 1022 is provided at the starting end of the sliding lower shell 102 in this embodiment, and the first annular mounting groove 1022 is recessed toward the inner side wall of the sliding lower shell 102, and the first damping pad 3 is installed in the first annular mounting groove 1022 and is sleeved on the outer periphery of the sliding arm 2.

[0049] It should be noted that, through the above design, installing the first damping pad 3 in the first annular mounting groove 1022 can prevent the first damping pad 3 from moving along the front and rear directions of the slide groove 5. In addition to playing an installation role, the first annular mounting groove 1022 also plays a limiting role, effectively ensuring that the first damping pad 3 can be used normally.

[0050] Furthermore, the second damping pad 4 in this embodiment is sleeved on the tail end portion of the sliding arm 2 .

[0051] It should be noted that, through the above-mentioned design boundary, a sufficient distance can be left between the second damping pad 4 and the first damping pad 3, thereby ensuring that the sliding arm 2 can produce a continuous damping effect during the sliding process.

[0052] Specifically, the rear end of the sliding arm 2 in this embodiment is provided with a second annular mounting groove 201, and the second annular mounting groove 201 is recessed toward the interior of the sliding arm 2;

[0053] The second damping pad 4 is installed in the second annular installation groove 201 .

[0054] It should be noted that, through the above design, installing the second damping pad 4 in the second annular mounting groove 201 can prevent the second damping pad 4 from moving along the front and rear directions of the slide groove 5. In addition to playing an installation role, the second annular mounting groove 201 also plays a limiting role, effectively ensuring that the second damping pad 4 can be used normally.

[0055] Furthermore, in order to make the second damping pad 4 and the sliding arm 2 more firmly installed, this embodiment further includes a locking screw;

[0056] A threaded hole 202 is provided in the second annular mounting groove 201;

[0057] The second damping pad 4 is provided with a through hole corresponding to the threaded hole 202;

[0058] The screw rod of the locking screw passes through the through hole and is threadedly connected to the threaded hole 202 so that the second damping pad 4 is locked in the second annular mounting groove 201 .

[0059] It should be noted that tightening the locking screw ensures that the second damping pad 4 is securely mounted in the second annular mounting groove 201. In addition to the method of securing with the locking screw, in this embodiment, an adhesive layer can be applied to the wall surface of the second annular mounting groove 201 to securely mount the second damping pad 4 in the second annular mounting groove 201.

[0060] Furthermore, the first damping pad 3 and the second damping pad 4 in this embodiment are both damping pads made of silicone.

[0061] It should be noted that, through the above design, since silicone can generate greater friction with other plastic parts, the first damping pad 3 and the second damping pad 4 made of silicone can achieve a damping effect.

[0062] Furthermore, an anti-slip pad is provided on the outer side wall of the head end portion of the outer side wall of the sliding arm 2 in this embodiment.

[0063] It should be noted that, through the above design, when the user's hand operates the sliding arm 2 to slide, the user's hand pinches the anti-slip pad, thereby preventing the hand from slipping, effectively improving the user experience.

[0064] See also Figures 1 to 6 , an embodiment of the present invention provides a headset, comprising a headset frame and the above-mentioned headset sliding arm 2 pulling structure;

[0065] The fixing bracket 1 in the pulling structure of the headphone sliding arm 2 is arranged on the inner side of the headband frame.

[0066] In the headphones of this embodiment, the sliding arm 2 is slidably arranged in the sliding groove 5, and the sliding arm 2 can be pulled and slid in the sliding groove 5; a first damping pad 3 is provided between the starting end of the sliding groove 5 and the sliding arm 2, and the first damping pad 3 is sleeved on the outer periphery of the sliding arm 2; a second damping pad 4 is sleeved on the sliding arm 2, and a protrusion 401 is provided on the outer side of the second damping pad 4, which abuts against the inner side wall of the sliding groove 5 to form an interference fit. Through the above design, when the sliding arm 2 is pulled out, the first damping pad 3 always abuts against the outer side wall of the sliding arm 2, and the protrusion 401 on the second damping pad 4 always abuts against the inner side wall of the sliding groove 5. The cooperation between the first damping pad 3 and the second damping pad 4 generates damping when the sliding arm 2 slides, thereby allowing the user to stably pull and retract the sliding arm 2, improving the user's operating feel, and facilitating the user to accurately adjust the position of the sliding arm 2, greatly improving the user experience.
