Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, specifically to an in-ear hearing aid battery compartment. Background Technology

[0002] Hearing aids, as essential devices to help people with hearing impairments improve their hearing, have become increasingly smaller in size with technological advancements, especially in-the-ear (ITE) hearing aids, which are favored by many users due to their discreetness and comfortable fit. However, there are currently some issues with the battery compartments of ITE hearing aids during use.

[0003] Based on the above, the inventors have discovered the following problems: Existing in-ear hearing aids have a buckle on the battery compartment cover. When the battery compartment cover is squeezed by a finger, the battery compartment deforms and the buckle on the battery compartment comes off the slot on the outer shell. Since the battery needs to be replaced frequently, the buckle on the battery compartment cover is prone to damage over time.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide an in-ear hearing aid battery compartment, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide an in-ear hearing aid battery compartment to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A battery compartment for an in-ear hearing aid includes a cover and a housing. The top of the housing and the bottom of the cover are fixedly connected. A battery is housed inside the cover. A PCB board is mounted on the top of the housing, and a copper electrode plate is mounted on the top of the PCB board. The outer side of the battery contacts one side of the copper electrode plate. An opening is provided on one side of the cover, and a battery compartment cover is located inside the opening. A first rotating shaft is rotatably connected to one end of the inner side of the battery compartment cover. The top of the first rotating shaft is rotatably connected to the top of the inner side of the cover. A button is located on the other side of the opening. A second rotating shaft is rotatably connected to the inner side of the button. The top of the second rotating shaft is rotatably connected to the top of the inner side of the cover. A V-shaped torsion spring for opening the battery compartment cover is sleeved on the outer side of the first rotating shaft. One end of the battery compartment cover and one end of the button are engaged. Further, one end of the V-shaped torsion spring is connected to the inner side of the battery compartment cover, and a torsion spring fixing seat is mounted on the other end of the V-shaped torsion spring. The top of the torsion spring fixing seat is fixedly connected to the top of the inner side of the cover. The beneficial effect of adopting the above-mentioned further solution is that, by connecting one end of the V-shaped torsion spring to the battery compartment cover and fixing the other end to the torsion spring fixing seat, when the button is released, the V-shaped torsion spring releases its elastic potential energy, pushes the battery compartment cover to rotate around the first pivot and spring open, thereby realizing the automatic opening of the battery compartment cover.

[0008] Furthermore, one end of the battery compartment cover is provided with an arc-shaped slot, and the inner side of the arc-shaped slot is engaged with one end of the button.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by engaging the inner side of the arc-shaped slot with one end of the button, a stable locking structure is formed, preventing the cover from opening on its own due to shaking or collision during the use of the hearing aid.

[0010] Furthermore, a spring retainer is installed at the top of the inner side of the cover, and a return spring is installed at one end of the spring retainer. One end of the return spring is fixedly connected to one side of the button.

[0011] The beneficial effect of adopting the above-mentioned further solution is that a return spring installed at one end of the spring fixing seat provides a reset force for the button. When the button is pressed to unlock the cover, the return spring pushes the button back to its original position when the button is released. Furthermore, a pair of conductive plates are provided at the top of the copper electrode plate, and the copper electrode plate is electrically connected to the battery through the conductive plates.

[0012] The advantage of adopting the above-mentioned further solution is that by providing a pair of conductive plates at the top of the copper electrode plate, a low-resistance conductive path is formed, ensuring that the battery power is efficiently transferred to the PCB board and other components of the hearing aid.

[0013] Furthermore, the bottom end of the first rotating shaft is rotatably connected to the top end of the housing.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the rotational stability of the first rotating shaft is improved by rotating the bottom end of the first rotating shaft and the top end of the housing.

[0015] Furthermore, the bottom end of the second rotating shaft is rotatably connected to the top end of the housing.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the rotational stability of the second shaft is improved by rotating the bottom end of the second shaft and the top end of the housing.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The battery compartment of this in-ear hearing aid consists of a cover and a housing forming the main structure of the battery compartment. A PCB board and copper plates provide electrical connection for the battery, supplying power to the hearing aid. The battery compartment cover is opened and closed via a first rotating shaft and a V-shaped torsion spring. A button, in conjunction with a second rotating shaft and a return spring, controls the opening and closing of the cover through a locking structure. When the button is pressed, the locking mechanism with the cover is released, and the V-shaped torsion spring opens the cover, facilitating battery replacement. One end of the V-shaped torsion spring is connected to the battery compartment cover, and the other end is fixed to a torsion spring mounting base. When the button is released, the V-shaped torsion spring releases its elastic potential energy, pushing the battery compartment cover to rotate around the first rotating shaft and open, thus achieving automatic opening of the battery compartment cover. This is achieved through the inner side of the arc-shaped slot and the button... One end engages to form a stable locking structure, preventing the cover from opening automatically due to shaking or collision during hearing aid use. A return spring is installed at one end of the spring fixing seat to provide a reset force for the button. When the button is pressed to unlock the cover, the return spring pushes the button back to its original position when the button is released. A pair of conductive plates are provided at the top of the copper electrode plate to form a low-resistance conductive path, ensuring efficient transmission of battery power to the PCB board and other components of the hearing aid. The bottom end of the first rotating shaft is rotatably connected to the top end of the housing, improving the rotational stability of the first rotating shaft. The bottom end of the second rotating shaft is rotatably connected to the top end of the housing, improving the rotational stability of the second rotating shaft. This utility model can effectively and conveniently open and close the battery compartment cover for users and improve the service life of the battery compartment, thus having high practical value.
