Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically a foldable headphone. Background Technology

[0002] In the current technology, most traditional headphones have a one-piece structure and a relatively fixed shape. This makes them inconvenient to store and carry when not in use due to their large size. For example, when placed in a bag, they take up a lot of space, making it impossible to put other items in the bag.

[0003] Therefore, there is an urgent need in the market for a type of over-ear headphone that can be easily folded and takes up less space. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a foldable headphone that solves the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foldable headphone, comprising a first frame and a second frame, the first frame and the second frame being hinged together by a pivot, both the first frame and the second frame having a rotating groove at their ends, a connecting block being rotatably installed in the rotating groove, an mounting shell being installed on the connecting block, a sliding sleeve being slidably connected to the first frame, a positioning bolt being slidably connected to the sliding sleeve, a positioning hole adapted to the positioning bolt being provided on the second frame, and a locking structure being provided between the connecting block and the rotating groove.

[0008] Preferably, the first frame has two symmetrical arc-shaped guide grooves, and the sliding sleeve has through holes adapted to the first frame and the second frame, with two protrusions adapted to the arc-shaped guide grooves inside the through holes.

[0009] Preferably, the locking structure includes a sliding hole on the connecting block, a movable plug slidably arranged in the sliding hole, and a locking groove adapted to the movable plug in the rotating groove.

[0010] Preferably, two symmetrical vertical guide grooves are formed on the inner wall of the sliding hole, and a vertical guide block is slidably arranged in the vertical guide groove and the vertical guide block is installed on the movable plug.

[0011] Preferably, a guide rod is provided in the vertical guide groove, and the vertical guide block is slidably arranged on the guide rod.

[0012] Preferably, a return spring is sleeved on the guide rod, with one end of the return spring abutting against the inner wall of the vertical guide groove and the other end of the return spring abutting against the vertical guide block.

[0013] Preferably, a pull ring is provided at the end of the movable plug away from the locking groove.

[0014] Compared with the prior art, this utility model provides a foldable headphone with the following advantages: This utility model, through its structure including a first frame, a second frame, and a sliding sleeve, allows the headphone to be folded when needed. The sliding sleeve can slide along the first frame away from the second frame, exposing the hinge between the first and second frames, allowing them to be folded. Unlocking the connecting blocks on the two mounting shells from the first and second frames allows the two connecting blocks to rotate along the first and second frames, achieving folding. Conversely, unfolding the headphone allows it to be unfolded. When the first and second frames are unfolded, the sliding sleeve can be slid to the connection point between them, and a positioning pin passes through the sliding sleeve and inserts into the positioning hole on the second frame to fix the sliding sleeve.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-5 A foldable headphone includes a first frame 1 and a second frame 2. The first frame 1 and the second frame 2 are hinged together by a pivot 14. The ends of the first frame 1 and the second frame 2 are provided with a rotating groove 11. A connecting block 6 is rotatably installed in the rotating groove 11. An installation shell 7 is installed on the connecting block 6. A sliding sleeve 3 is slidably connected to the first frame 1. A positioning bolt 4 is slidably connected to the sliding sleeve 3. A positioning hole 16 adapted to the positioning bolt 4 is provided on the second frame 2. A locking structure is provided between the connecting block 6 and the rotating groove 11.

[0025] With the structure of the first frame 1, the second frame 2, and the sliding sleeve 3, when the headphones need to be folded, the sliding sleeve 3 can be slid along the first frame 1 away from the second frame 2. At this time, the hinge of the first frame 1 and the second frame 2 is exposed, and the first frame 1 and the second frame 2 can be folded. The connecting blocks 6 on the two mounting shells 7 can be unlocked from the first frame 1 and the second frame 2, and the two connecting blocks 6 can be rotated along the first frame 1 and the second frame 2 to achieve folding. Conversely, the headphones can be unfolded. When the first frame 1 and the second frame 2 are unfolded, the sliding sleeve 3 can be slid to the connection between the first frame 1 and the second frame 2, and the positioning pin 4 passes through the sliding sleeve 3 and is inserted into the positioning hole 16 on the second frame 2 to fix the sliding sleeve 3.

[0026] Specifically, in this embodiment, the first frame 1 has two symmetrical arc-shaped guide grooves 5, and the sliding sleeve 3 has through holes 15 that are adapted to the first frame 1 and the second frame 2. Two protrusions 13 that are adapted to the arc-shaped guide grooves 5 are provided in the through holes 15.

[0027] The movement range of the sliding sleeve 3 can be limited by the cooperation of the arc-shaped guide groove 5 and the protrusion 13, thus preventing the sliding sleeve 3 from detaching from the first frame 1.

[0028] Specifically, in this embodiment, the locking structure includes a sliding hole 10 on the connecting block 6, a movable plug 9 slidably arranged in the sliding hole 10, and a locking groove 8 adapted to the movable plug 9 in the rotating groove 11.

[0029] By setting the movable plug 9, when the movable plug 9 is inserted into the locking groove 8, the connecting block 6 can be limited and fixed in the rotating groove 11.

[0030] Specifically, in this embodiment, two symmetrical vertical guide grooves 18 are provided on the inner wall of the sliding hole 10, and a vertical guide block 19 is slidably arranged in the vertical guide groove 18. The vertical guide block 19 is installed on the movable plug 9.

[0031] The vertical guide groove 18 and the vertical guide block 19 cooperate to guide the movement direction of the movable plug 9 and limit the movement range of the movable plug 9.

[0032] Specifically, in this embodiment, a guide rod 17 is provided in the vertical guide groove 18, and a vertical guide block 19 is slidably arranged on the guide rod 17. A reset spring 20 is sleeved on the guide rod 17. One end of the reset spring 20 abuts against the inner wall of the vertical guide groove 18, and the other end of the reset spring 20 abuts against the vertical guide block 19.

[0033] By setting the return spring 20, the vertical guide block 19 can always be pressed against the inner wall of one side of the vertical guide groove 18 under normal conditions, so that the movable plug 9 is kept inserted in the locking groove 8 when not manually operated. When it is necessary to release the lock of the connecting block 6, the movable plug 9 can be pulled to drive the vertical guide block 19 to slide along the vertical guide groove 18 and squeeze the return spring 20. At this time, the movable plug 9 moves away from the locking groove 8. After the movable plug 9 is released, the elastic potential energy of the return spring 20 can make the movable plug 9 automatically reset.

[0034] Specifically, in this embodiment, a pull ring 12 is provided at the end of the movable plug 9 that is away from the locking groove 8.

[0035] It should be noted that the two mounting shells contain the internal structure of conventional headphones. The headphone structure, working principle, and usage are the same as existing technologies, and will not be described in detail here.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
