Description

Technical Field

[0001] This utility model relates to the technical field of Bluetooth headsets, and in particular to a sliding and foldable over-ear Bluetooth headset. Background Technology

[0002] Bluetooth headsets are wireless headphones that use Bluetooth technology to communicate via radio waves in the 2.4 GHz band, replacing traditional wired headphones. Bluetooth headsets free users from the constraints of wires, allowing for free calls and music enjoyment. Bluetooth technology is a low-cost, high-capacity, short-range wireless communication standard with wide compatibility and application range. Common types of Bluetooth headsets include in-ear, ear-hook, over-ear, and bone conduction Bluetooth headsets.

[0003] Currently, existing over-ear Bluetooth headphones often employ a telescopic design due to the varying ages and head sizes of their users, as well as the inherent differences in head dimensions between individuals. However, traditional sliding telescopic Bluetooth headphones only offer telescopic functionality and lack a fixed fit. During wear, unintentional bumps or scratches by the wearer may cause unintended length adjustments, leading to discomfort.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: This utility model provides a slidable foldable Bluetooth headset, as shown in Figures 1-4, including a headset body (1), a connecting frame (11), two sets of connecting posts (12), two sets of earphone heads (13), two sets of folding components (2) and two sets of adjustment mechanisms (5). The headset body (1) is provided with folding components (2) at both ends. The outer walls of the two sets of folding components (2) are provided with connecting posts (12). The other ends of the two sets of connecting posts (12) are provided with earphone heads (13). The two sets of adjustment mechanisms (5) are respectively provided on the outer walls of the corresponding earphone heads (13).

[0025] The adjustment mechanism (5) includes a limiting block (51), a fixing plate (52), a limiting plate (53), a storage hole (54), multiple sets of springs (55), multiple sets of latches (56), and a locking hole (57). The outer wall of the connecting column (12) is provided with a limiting block (51). The inside of the limiting block (51) is slidably connected to the fixing plate (52). The upper end of the fixing plate (52) is provided with a limiting plate (53). The side wall of the fixing plate (52) is provided with storage holes (54) at equal intervals. Springs (55) are respectively provided in the storage holes (54). The other end of the springs (55) is fixed with a latch (56). The side wall of the limiting block (51) is provided with a locking hole (57).

[0026] When the length of the Bluetooth headset needs to be adjusted, the wearer can first press the latch (56). At this time, the latch (56) will slide down along the inner wall of the storage hole (54). At the same time, the latch (56) will apply pressure to the spring (55). The spring (55) will store and contract until the latch (56) is stored in the storage hole (54). Then pull the earphone head (13). At this time, the earphone head (13) will drive the fixing plate (52) to slide down along the inner wall of the limiting block (51). When the storage hole (54) and the latch hole (57) coincide, the latch (56) will pop out and reset through the spring (55). When the latch (56) is engaged in the latch hole (57), the Bluetooth headset is fixed at the current length.

[0027] Furthermore, a connection hole (14) is provided on the outer wall of the earphone head (13). Through the connection hole (14), the wearer can connect the Bluetooth earphone to the terminal using a connection cable.

[0028] Furthermore, a connecting rod (4) is provided on the outer wall of the connecting frame (11). The movement trajectory of the earphone head (13) can be restricted by the connecting rod (4).

[0029] Furthermore, the folding assembly (2) includes a connecting block (21), a central shaft (22), and a connecting groove (23). The connecting frame (11) has a connecting block (21) at its front end, and the connecting block (21) has a central shaft (22) on its side wall. The two ends of the central shaft (22) are connected to the side wall of the connecting groove (23). When the Bluetooth headset is not in use, the user can rotate the headset head (13). At this time, the headset head (13) will drive the connecting post (12) to rotate around the central shaft (22), thereby folding the headset head (13) and the connecting frame (11) together.

[0030] Furthermore, the outer wall of the latch (56) matches the inner wall size of the receiving hole (54), and the number of positions of the latch (56) and spring (55) matches the number of positions of the receiving hole (54). By setting the outer wall of the latch (56) to match the inner wall size of the receiving hole (54), the latch (56) can be better stored in the receiving hole (54).

[0031] Furthermore, the connecting block (21) can rotate within the connecting groove (23) via the central shaft (22). The arrangement of the connecting block (21) rotating within the connecting groove (23) via the central shaft (22) allows for better folding of the earphone head (13) and the connecting bracket (11).

[0032] Furthermore, the outer wall dimension of the latch (56) matches the inner wall dimension of the latch hole (57), and the inner wall dimension of the limiting block (51) matches the outer dimension of the fixing plate (52). By matching the inner wall dimension of the limiting block (51) with the outer dimension of the fixing plate (52), the stability between the earphone head (13) and the connecting bracket (11) is increased.

[0033] Furthermore, a sponge pad (3) is provided on the outer wall of the connecting frame (11). The sponge pad (3) increases the comfort of the wearer when wearing the Bluetooth headset.

[0034] Working principle: When the length of the Bluetooth headset needs to be adjusted, the wearer can first press the latch (56). At this time, the latch (56) will slide down along the inner wall of the storage hole (54). At the same time, the latch (56) will apply pressure to the spring (55). The spring (55) will store and contract until the latch (56) is stored in the storage hole (54). Then pull the earphone head (13). At this time, the earphone head (13) will drive the fixing plate (52) to slide down along the inner wall of the limiting block (51). When the storage hole (54) and the latch hole (57) coincide, the latch (56) will pop out and reset through the spring (55). When the latch (56) is engaged in the latch hole (57), the Bluetooth headset is fixed at the current length. Through the connection hole (14), the wearer can connect the Bluetooth headset to the terminal using a connecting cable; through the connection rod (4), the movement trajectory of the earphone head (13) can be restricted; when the Bluetooth headset is not needed, the user can rotate the earphone head (13), at which time the earphone head (13) will drive the connecting post (12) to rotate around the central axis (22), thereby folding the earphone head (13) and the connecting frame (11) together; through the outer wall of the latch (56) and the inner wall of the storage hole (54) being the same size The fitting design allows the latch (56) to be better stored in the storage hole (54); the connection block (21) can rotate in the connection groove (23) via the central shaft (22), which allows the earphone head (13) and the connecting frame (11) to be folded together; the inner wall size of the limiting block (51) matches the outer size of the fixing plate (52), thereby increasing the stability between the earphone head (13) and the connecting frame (11); the sponge pad (3) adds to the comfort of the wearer when wearing the Bluetooth earphone.

[0035] 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.
