[0028] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0029] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The adjustable silicone ear hooks provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] Example 1:

[0032] This application provides an adjustable silicone ear hook, including a temple 1 and an ear hook 2. The temple 1 is provided with a mounting groove 3 extending along its length. One end of the ear hook 2 is fixedly assembled to one end of the mounting groove 3, and the other end is slidably controlled to enter and exit the mounting groove 3 by a limiting member 4, so as to realize the length adjustment and storage of the ear hook 2.

[0033] In this embodiment of the application, a plug 5 is also included, which is inserted through the temple 1 and the fixed end of the silicone ear loop.

[0034] like Figures 1 to 5 As shown, due to the above-mentioned structure, the mounting groove 3 extending along the length direction on the temple 1 provides a stable reference support for the adjustment of the ear hook 2. The design of the ear hook 2, which is "fixed at one end and fixed at the other end by the limiting member 4", breaks the existing adjustment mode that can only slide back and forth. Users can flexibly adjust the relative assembly position of the ear hook 2 and the temple 1 according to their own head size and ear contour characteristics to achieve personalized adaptation of the effective wearing length of the ear hook 2. At the same time, when the ear hook 2 is not in use, it can be completely stored in the mounting groove 3 to avoid the problem of the ear hook 2 scratching foreign objects when idle. The structure of the insert 5 passing through the temple 1 and one end of the ear hook 2 can directly strengthen the assembly strength of the fixed end of the ear hook 2, reduce the risk of the ear hook 2 breaking at the root due to long-term stress, and lay the foundation for the service life of the product.

[0035] Example 2:

[0036] In this embodiment, in addition to the structural features of the aforementioned embodiments, the limiting member 4 includes a first sliding groove 41, a second sliding groove 42, and a sliding block 43. The first sliding groove 41 and the second sliding groove 42 are respectively opened on the temple 1 and the ear loop 2, and the sliding block 43 is simultaneously slidably installed in the first sliding groove 41 and the second sliding groove 42.

[0037] In this embodiment of the application, the sliding block 43 is made of Tr rubber.

[0038] like Figures 1 to 5 As shown, due to the above structure, the corresponding arrangement of the first groove 41 and the second groove 42 forms a bidirectional guide channel. The sliding block 43 made of Tr rubber (i.e., thermoplastic rubber TPR, Shore hardness 60-70A, with good elasticity and friction damping characteristics) is simultaneously embedded in the double grooves. On the one hand, it realizes the synchronous sliding guidance of the sliding block 43, ensuring that the adjustment process of the ear hook 2 is smooth and stable, avoiding the problems of jamming and adjustment jerking that may occur in the "toothed belt-protrusion" cooperation in the prior art. On the other hand, the elasticity and friction characteristics of Tr rubber itself enable the sliding block 43 to form a stable damping positioning effect at any adjustment position, effectively preventing the ear hook 2 from shifting on its own due to slight external forces (such as turning the head or touching) during the wearing process, significantly improving the structural stability after adjustment, and making the wearing state more durable and reliable after fitting.

[0039] Example 3:

[0040] In this embodiment, in addition to the structural features included in the aforementioned embodiments, the first sliding groove 41 and the insert block 5 are both disposed on the outer side of the temple 1.

[0041] like Figures 1 to 5 As shown, due to the above structure, the first sliding groove 41 and the insert block 5 are both located on the outside of the temple 1. The design of the outside layout allows users to intuitively observe the adjustment position of the ear hook 2 and operate it accurately without blindly fumbling around. This further optimizes the convenience of adjustment and is especially suitable for scenarios where the wearing status needs to be frequently adjusted, adapting to the operating habits of different users.

[0042] Example 4:

[0043] In this embodiment, in addition to the structural features of the aforementioned embodiments, an anti-detachment structure 44 is also included, which is used to prevent the sliding block 43 from detaching from the first slide groove 41 and the second slide groove 42.

[0044] In this embodiment of the application, the anti-detachment structure 44 includes a slot 441 and a plurality of protrusions 442. Each protrusion 442 is disposed on the adjacent side of the top and bottom surfaces of the first sliding groove 41 and the second sliding groove 42. The slot 441 is disposed on the periphery of the sliding block 43 and is slidably engaged with each protrusion 442.

[0045] In this embodiment of the application, the contact surface between the protruding edge 442 in the first groove 41 and the slot 441 is wavy.

[0046] In this embodiment of the application, the outer side of the temple 1 is provided with a scale corresponding to the first sliding groove 41.

[0047] like Figures 1 to 5 As shown, due to the above structure, the protruding edge 442 provided on the adjacent sides of the top and bottom surfaces of the first slide groove 41 and the second slide groove 42 forms a sliding engagement with the peripheral slot 441 of the insert block 5, thus providing comprehensive limiting constraints on the sliding block 43 and the insert block 5 from both above and below, ensuring that the ear hook 2 maintains a stable assembly state during long-term adjustment and high-frequency use. At the same time, the sliding engagement design of the protruding edge 442 and the slot 441 does not affect the smoothness of adjustment, achieving a dual balance of "reliable anti-detachment" and "flexible adjustment", thereby improving the overall structural reliability of the product.

[0048] The contact surface between the raised edge 442 and the slot 441 is wavy, which provides sliding damping and graded positioning for the sliding block 43 through the concave-convex interlocking structure; the scale on the surface of the temple 1 provides an intuitive positional reference for adjusting the ear hooks 2. In practical applications, when only the wavy contact surface is used, the user can adjust a pair of ear hooks 2 to a symmetrical state simultaneously by relying on the feedback of the interlocking damping; when only the scale is set, the adjustment positions of the two ear hooks 2 can be directly aligned through the scale markings to achieve precise symmetry; and when the wavy contact surface and the scale are used together, the interlocking positioning can ensure the structural stability after adjustment, and the scale can be used to achieve visual and precise adjustment, further improving the ease of operation and symmetry accuracy, and adapting to the adjustment needs of different usage scenarios.

[0049] Example 5:

[0050] In this embodiment, in addition to the structural features of the aforementioned embodiments, the outward-facing sidewalls of each protrusion 442 in the first groove 41 are inclined guide surfaces, used to guide the sliding block 43 into the second groove 42.

[0051] like Figures 1 to 5 As shown, due to the above structure, the inclined guide surface with the inner convex edge 442 of the first slide groove 41 facing outward has a precise guiding function. During assembly, it can provide a clear insertion path for the sliding block 43, helping the sliding block 43 to quickly and accurately align with the second slide groove 42 without repeated alignment and calibration, which significantly reduces the assembly difficulty of the ear hook 2 and the temple 1. In the subsequent adjustment process, the guide surface can also reduce the frictional resistance between the sliding block 43 and the slide groove, making the adjustment operation more effortless and the feel smoother. This further optimizes the assembly convenience of the product and the user adjustment experience, and solves the problems of low assembly efficiency and poor adjustment feel in the prior art.

[0052] Example 6:

[0053] In this embodiment, in addition to the structural features included in the aforementioned embodiments, the ear loop 2 has several perforations 6.

[0054] In this embodiment of the application, the ear hook 2 is made of silicone and has an initial arc shape.

[0055] like Figures 1 to 5 As shown, due to the aforementioned structure, the silicone ear hook 2 possesses excellent softness and fit. Combined with its initial curved shape, it naturally conforms to the contour of the back of the ear, providing a close fit without pressure, effectively reducing discomfort caused by prolonged wear. The numerous perforations 6 on the ear hook 2 quickly allow air to escape from the area where the ear and ear hook 2 are in contact, accelerating sweat evaporation and completely solving the problem of stuffiness and stickiness caused by sweat accumulation in the wearing area of ​​the ear hook 2 in existing technologies, significantly improving breathability. This design is particularly suitable for summer or sports and other scenarios where sweating is likely, broadening the product's applicable scenarios. At the same time, the wear-resistant and anti-aging properties of silicone material further extend the service life of the ear hook 2.
