Description

Technical Field

[0001] This utility model relates to the field of bone conduction hearing aid technology, specifically to a toggle component for a bone conduction hearing aid. Background Technology

[0002] In the design of bone conduction hearing aids, the toggle component is the core interactive component for realizing the power on / off function. Its operational stability, waterproof performance, and structural reliability directly affect the user experience.

[0003] Traditional toggle mechanisms often use a single silicone ring or glue seal, which is prone to aging and cracking after long-term use, allowing moisture and sweat to seep into the housing and cause short circuits. Furthermore, existing toggle mechanisms often employ an integrated push-button design, with the connection to the sliding switch secured only by a simple clip. Frequent toggling can lead to wear and loosening, resulting in unclear operational feedback or even accidental activation. Therefore, we propose a toggle mechanism for bone conduction hearing aids. Utility Model Content

[0004] The purpose of this invention is to provide a toggle assembly for a bone conduction hearing aid to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a toggle assembly for a bone conduction hearing aid, comprising a shell, an inner shell, a metal push knob, waterproof silicone, and a card;

[0006] The metal push-twist is installed in the grooves opened in the outer shell and the inner shell. The metal push-twist fork arm passes through the outer shell and the inner shell and engages with the sliding switch. The waterproof silicone is embedded in the groove on the inner side of the metal push-twist. The card is inserted into the limiting groove of the metal push-twist fork arm, and the card makes the waterproof silicone and the inner shell interference fit.

[0007] Preferably, the fork arm of the metal push knob has a "U" shaped structure, and the metal push knob passes through the outer shell and inner shell and engages with the sliding switch.

[0008] Preferably, the waterproof silicone fills the space between the inner groove of the hardware push knob and the inner shell to form a sealing structure to prevent moisture from entering the interior of the outer shell.

[0009] Preferably, the card is inserted into the limiting groove of the hardware push-twist fork arm from the side of the inner shell facing away from the waterproof silicone, in order to limit the axial movement of the hardware push-twist and enhance the sealing fit between the waterproof silicone and the inner shell.

[0010] Preferably, the inner shell and the outer shell are assembled after separate processing, and the corner of the groove where the hardware push-twist is located adopts a design without R-angle.

[0011] Compared with existing technologies, the advantages of this invention are as follows: By using a metal push-twist fork arm to engage the sliding switch, and combining it with waterproof silicone to form an interference-sealed structure with the card, moisture penetration is effectively prevented, solving the problem of easy aging and cracking of traditional seals. The metal push-twist "U"-shaped fork arm enhances the stability of the engagement with the sliding switch, reducing accidental activation. The inner and outer shells are machined separately, and the grooves have no rounded corners, improving fitting precision, simplifying the assembly process, and facilitating maintenance and replacement. The overall structure improves the operational stability, waterproof reliability, and assembly efficiency of the bone conduction hearing aid's toggle assembly. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] Example 1: A toggle assembly for a bone conduction hearing aid, comprising an outer shell 1, an inner shell 11, a metal push knob 2, waterproof silicone 3, and a card 4;

[0020] The metal push knob 2 is installed in the groove 101 opened in the outer shell 1 and the inner shell 11. The fork arm of the metal push knob 2 passes through the outer shell 1 and the inner shell 11 and is engaged with the sliding switch 5. The waterproof silicone 3 is embedded in the groove 101 on the inner side of the metal push knob 2. The card 4 is inserted into the limiting groove of the fork arm of the metal push knob 2, and the card 4 makes the waterproof silicone 3 and the inner shell 11 interference fit.

[0021] During use and assembly, first embed the waterproof silicone 3 into the groove 101 inside the metal push-touch 2, then pass the fork arm of the metal push-touch 2 through the corresponding holes in the outer shell 1 and the inner shell 11, so that the fork arm engages with the sliding switch 5. Next, insert the card 4 from the side of the inner shell 11 facing away from the waterproof silicone 3. After the card 4 engages with the fork arm's limiting groove, it will compress the waterproof silicone 3, making it fit tightly against the inner shell 11, forming an interference fit. During use, push the metal push-touch 2 with your finger to slide it within the groove 101. The fork arm drives the sliding switch 5 to switch between on and off states, realizing the power on / off function. The card 4 restricts the axial movement of the metal push-touch 2, while the waterproof silicone 3 seals the gap between the push-touch and the shell, preventing sweat and moisture from seeping into the interior of the outer shell 1.

[0022] Example 2: The technical solution of this example, which differs from that of Example 1, is as follows: the fork arm of the metal push-twist 2 has a "U" shaped structure, and the metal push-twist 2 passes through the outer shell 1 and the inner shell 11 and is engaged with the sliding switch 5. Waterproof silicone 3 is filled between the inner groove 101 of the metal push-twist 2 and the inner shell 11 to form a sealing structure to prevent moisture from entering the interior of the outer shell 1. The card 4 is inserted into the limiting groove of the fork arm of the metal push-twist 2 from the side of the inner shell 11 facing away from the waterproof silicone 3 to limit the axial movement of the metal push-twist 2 and to strengthen the sealing fit between the waterproof silicone 3 and the inner shell 11. The inner shell 11 and the outer shell 1 are assembled after separate processing, and the corner of the groove 101 where the metal push-twist 2 is located adopts a design without R-angle.

[0023] In use, the metal push knob 2, which has a "U"-shaped fork arm, is pushed. The fork arm engages with the sliding switch 5 and moves it laterally to switch the circuit on and off. The "U"-shaped structure enhances the engagement stability between the fork arm and the sliding switch 5 and reduces the free travel when turning. Waterproof silicone 3 is filled between the groove 101 on the inner side of the metal push knob 2 and the inner shell 11. When the metal push knob 2 slides, the card 4 presses the waterproof silicone 3 from the inside of the inner shell 11, so that it maintains an interference fit with the inner shell 11, forming a dynamic sealing barrier to prevent moisture from seeping in along the movement trajectory of the push knob. The inner shell 11 and the outer shell 1 are assembled after separate processing. The corner of the groove 101 has no R-angle design, which reduces the gap between the metal push knob 2 and the groove 101 and further improves the sealing accuracy.

[0024] 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.
