Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Referring to fig. 1-6, an embodiment of the present invention provides a hearing aid, which may include a housing 1, a connection cover assembly 2, and a limit edge 3, where a receiving cavity 11 is formed on the housing 1, one end of the connection cover assembly 2 is rotatably connected to the housing 1, and the other end is detachably connected to the housing 1, so as to seal the receiving cavity 11, where a battery receiving cavity 24 is disposed on the connection cover assembly 2 located in the receiving cavity 11. The limiting edge 3 is located on the connecting cover assembly 2 to cooperate with the battery accommodating cavity 24 to limit the battery 6.

In the embodiment of the present invention, the accommodating cavity 11 is used for accommodating relevant components of the hearing aid, such as the battery 6, conductive plates at two ends of the battery 6, and a speaker assembly. The battery 6 may be a button battery 6. A rotation shaft may be mounted to one end of the connection cap assembly 2 so as to be rotatably connected with the housing 1 through the rotation shaft. The other end of the connecting cover assembly 2 (the end which is rotatably connected with the connecting cover assembly 2 and the shell 1 is opposite to each other) is detachably connected with the shell 1, so that the quick assembly and disassembly of the connecting cover assembly 2 and the replacement of the battery 6 can be realized. Wherein, the detachable connection can comprise a clamping connection mode, a threaded connection mode and the like. The receiving chamber 11 is closed by the connection cap assembly 2 in a state that the other end of the connection cap assembly 2 is detachably connected with the housing 1.

And, a battery accommodating cavity 24 is provided on the connection cover assembly 2 located in the accommodating cavity 11, wherein the battery accommodating cavity 24 is used for accommodating the battery 6. Therefore, when the connecting cover assembly 2 is released from the sealing of the accommodating cavity 11 in the process of replacing the battery 6, the battery 6 can be taken out while the connecting cover assembly 2 is rotated outwards from the accommodating cavity 11, so that the battery 6 can be replaced conveniently.

In the embodiment of the present invention, the limiting edge 3 is configured to cooperate with the battery accommodating cavity 24 to limit the battery 6. For example, the battery accommodating cavity 24 is configured to form a radial limit for the battery 6, and the limit edge 3 may form an axial limit for the battery 6. So that the battery 6 can be taken out while the connection cap assembly 2 is rotated outward from the receiving chamber 11, and the connection firmness of the battery 6 on the connection cap assembly 2 is ensured. Thereby avoiding the situation that the battery 6 falls out of the receiving chamber 11 when the connection cap assembly 2 is screwed outward. Thereby, the connection cap assembly 2 rotates around the housing 1, and when it is rotated out of the receiving chamber 11, a force can be applied to the connection cap assembly 2. Thereby releasing the limit of the battery 6 under the action of the force. For example, the axial limit or the radial limit of the battery 6 is released. Thereby greatly improving the convenience of replacing the battery 6 by enlarging the operation space for placing or taking the battery 6. For example, the aged, who is not mobility-impaired, or the user group, who is relatively weak, can more easily perform battery replacement.

In summary, the embodiment of the invention discloses a hearing aid, which may include a housing 1, a connection cover assembly 2 and a limit edge 3, wherein a containing cavity 11 is formed on the housing 1, one end of the connection cover assembly 2 is rotatably connected to the housing 1, and the other end is detachably connected to the housing 1 to seal the containing cavity 11, wherein a battery containing cavity 24 is provided on the connection cover assembly 2 located in the containing cavity 11. The limiting edge 3 is located on the connecting cover assembly 2 to cooperate with the battery accommodating cavity 24 to limit the battery 6. Therefore, when the battery 6 is fixed through the connecting cover assembly 2, the battery 6 is taken out through the rotation of the connecting cover assembly 2, and the operating space for dismounting the battery 6 is enlarged, so that the convenience of replacing the battery 6 can be improved.

In an alternative embodiment of the invention, referring to fig. 4, 5 and 6, the connecting cover assembly 2 may include a first connecting cover 21, a second connecting cover 22 and a snap assembly 23, wherein:

the first connecting cover 21 is rotatably connected to the housing 1, and the second connecting cover 22 is rotatably connected to an end of the first connecting cover 21 remote from the housing 1. The buckle assembly 23 is disposed between the first connection cover 21 and the second connection cover 22, so that the first connection cover 21 and the second connection cover 22 are fixed by the buckle assembly 23, and the first connection cover 21 and the second connection cover 22 form radial limitation on the battery 6 under the condition of forming fixation.

In the embodiment of the present invention, the first connection cover 21 and the second connection cover 22 may be combined to form a closure of the accommodating cavity 11. Wherein the first connecting cover 21 is rotatably connected to the housing 1, and the second connecting cover 22 is rotatably connected to an end of the first connecting cover 21 remote from the housing 1. Wherein, the first connecting cover 21 and the second connecting cover 22 can be rotatably connected by a rotating shaft, and the fastening component 23 is disposed at the rotation connection position between the first connecting cover 21 and the second connecting cover 22. The first connecting cover 21 and the second connecting cover 22 can be fastened and fixed by the fastening component 23.

Therefore, when the battery 6 is replaced, the battery 6 can be taken out while the connecting cover assembly 2 rotates outwards from the accommodating cavity 11, and the clamping connection between the first connecting cover 21 and the second connecting cover 22 is kept fixed, so that the connection firmness of the battery 6 on the connecting cover assembly 2 is ensured, and the situation that the battery 6 falls off and the like when the connecting cover assembly 2 rotates outwards from the accommodating cavity 11 can be avoided. When the connection cap assembly 2 is rotated around the housing 1 to a proper position outside the receiving chamber 11, a force may be applied to the second connection cap 22. Thereby releasing the engagement between the first and second connection covers 21 and 22 by the action of the force. At this time, the second connection cover 22 may be rotated around the rotational connection with the first connection cover 21, and the radial restriction of the battery 6 may be released by expanding the space of the battery accommodating chamber 24. Thereby enlarging the operation space for placing or taking the battery 6 and greatly improving the convenience of replacing the battery 6. For example, the elderly with impaired mobility, or the weaker user group, can be more easily battery-exchanged, thereby further improving the product applicability of the hearing aid.

In an alternative embodiment of the invention, the limiting edge 3 is disposed on the first connecting cover 21, and/or the limiting edge 3 is disposed on the second connecting cover 22, so as to form an axial limit for the battery 6.

In this embodiment of the present invention, the limiting edge 3 may be located on the first connecting cover 21, for example, the limiting edge 3 and the first connecting cover 21 may be in an integrated structure, so that in the case that the first connecting cover 21 and the second connecting cover 22 cooperate to form a radial limit for the battery 6, an axial limit is formed for the battery 6 by the limiting edge 3 located on the first connecting cover 21.

In other embodiments, as shown with reference to fig. 3, the limiting edge 3 may be located on the second connection cover 22, for example, the limiting edge 3 and the second connection cover 22 may be in an integral structure, so that in the case that the first connection cover 21 and the second connection cover 22 cooperate to form radial limitation of the battery 6, axial limitation is formed on the battery 6 by the limiting edge 3 located on the second connection cover 22.

In still other embodiments, the limit edge 3 may be disposed on the first connection cover 21 and the second connection cover 22 at the same time. For example, the limit edge 3 provided on the first connecting cover 21 and the first connecting cover 21 may be in an integral structure. The limiting edge 3 disposed on the second connecting cover 22 and the second connecting cover 22 may be in an integral structure. Whereby in the case where the first and second connection covers 21 and 22 cooperate to form radial limitation of the battery 6, axial limitation of the battery 6 is simultaneously formed by the limitation sides 3 on the first connection cover 21 and the limitation sides 3 on the second connection cover 22. In summary, the limit edge 3 is matched with the battery accommodating cavity 24 to form radial limit and axial limit for the battery 6, so that the connection firmness of the battery 6 is ensured.

In an alternative embodiment of the invention, as shown with reference to fig. 4, 5 and 6, the catch assembly 23 may comprise a first catch 231 and a second catch 232. The first buckle 231 is disposed on an end portion of the first connection cover 21 near the second connection cover 22. The second buckle 232 is disposed on the end portion of the second connection cover 22 near the first connection cover 21. When the second connecting cover 22 is forced to rotate around the first connecting cover 21, the second buckle 232 is separated from the limit of the first buckle 231.

In an embodiment of the present invention, the buckle assembly 23 may include a first buckle 231 and a second buckle 232, where the first buckle 231 is disposed on an end portion of the first connection cover 21 near the second connection cover 22. Wherein, the first buckle 231 and the first connection cover 21 may be in an integrated structure. The second buckle 232 is disposed on the end portion of the second connection cover 22 near the first connection cover 21. Wherein, the second buckle 232 and the second connection cover 22 may be in an integral structure. In other words, the first and second hooks 231 and 232 are respectively located at the rotational connection of the first and second connection covers 21 and 22.

Referring to fig. 4 and 5, when the second connection cover 22 is forced around the first connection cover 21 and the rotation of the battery receiving chamber 24 is reduced (also the rotation of the second connection cover 22 is understood as being inward), the second catch 232 slides along one end surface of the first catch 231 along with the second connection cover 22 in a pressing contact manner onto the other end surface of the first catch 231. The first fastening buckle 231 has an inclined surface on one end, so that the second fastening buckle 232 can deform at an inclination angle when pressed against the first fastening buckle 231. Upon withdrawal of the force on the second connection cover 22, the other end surface of the first catch 231 is in press contact with the second catch 232, defining the position of the second catch 232, while defining the swiveling movement of the second connection cover 22. At this time, the first connection cover 21 and the second connection cover 22 cooperate to form a battery accommodating chamber 24 that limits the battery 6. For example, the cross-sectional shape of the first buckle 231 may be a right triangle.

Therefore, when the battery 6 is replaced, the battery 6 can be taken out while the connecting cover assembly 2 rotates outwards from the accommodating cavity 11, and the clamping connection between the first connecting cover 21 and the second connecting cover 22 is kept fixed, so that the connection firmness of the battery 6 on the connecting cover assembly 2 is ensured. The situation that the batteries 6 fall out of the accommodating cavity 11 is avoided when the connection cover assembly 2 rotates outwards.

Referring to fig. 6, when the coupling cap assembly 2 is rotated around the housing 1 to a proper position outside the receiving chamber 11, a force may be applied to the second coupling cap 22. Thereby, the second buckle 232 is deformed to slide from the other end face of the first buckle 231 to the position of one end face of the second buckle 232 under the action of the force, so that the clamping relationship between the first connecting cover 21 and the second connecting cover 22 is released. At this time, the second connecting cover 22 rotates freely around the rotational connection with the first connecting cover 21 (it can be understood that the second connecting cover 22 rotates outwards), and the radial limitation of the battery 6 is released by expanding the space of the battery accommodating cavity 24. Thereby enlarging the operation space for placing or taking the battery 6 and greatly improving the convenience of replacing the battery 6. For example, the aged, who is not mobility-impaired, or the user group, who is relatively weak, can more easily perform battery replacement. Thereby further improving the product suitability of the hearing aid.

In an alternative embodiment of the invention, the first latch 231 and the second latch 232 are made of acetal resin.

In the embodiment of the invention, the acetal resin (POM) has the performances of fatigue resistance, wear resistance, impact resistance and the like. The first buckle 231 and the second buckle 232 made of the POM material may have better deformation performance. Thereby extending the service life of the catch assembly 23 and optimizing the product performance of the hearing aid.

In an alternative embodiment of the invention, referring to fig. 4, the first connection cover 21 is disposed near the end face of the battery 6 and the second connection cover 22 is disposed near the end face of the battery 6 in a co-circle.

In an alternative embodiment of the invention, the first connection cover 22 is adjacent to the end face of the battery 6 and the second connection cover 22 is adjacent to the end face of the battery 6, and the sectional shape in the radial direction of the battery 6 is a circular arc shape of more than one half.

In the embodiment of the present invention, the first connection cover 21 is disposed close to the end face of the battery 6 and the second connection cover 22 is disposed close to the end face of the battery 6 in a co-circle. That is, the cross-sectional shape of the chamber wall of the battery housing chamber 24 in the radial direction is a circular arc shape of more than one half. Thus, when the battery 6 is assembled, the battery 6 can be axially limited by the limiting edge 3 in advance. The second connection cover 22 is then rotated until the first and second hooks 231 and 232 are capable of being fastened and fixed. Thereby effecting the installation of the battery 6 in the battery receiving chamber 24. Wherein, in the case that the first connection cover 21 is close to the end face of the battery 6 and the second connection cover 22 is close to the end face of the battery 6 and is arranged in a co-circle, the battery 6 and the battery accommodating cavity 24 are in clearance fit, so that the connection stability of the battery 6 can be further improved.

In an alternative embodiment of the invention, as shown in fig. 1, 2 and 3, the end surface of the second connecting cover 22 away from the battery 6 is outwardly extended with a handle 4, the second connecting cover 22 is extended into the accommodating cavity 11, and the handle 4 is extended to the outer surface of the housing 1.

In an embodiment of the present invention, the handle 4 and the second connecting cover 22 may be integrally formed. When the first connecting cover 21 and the second connecting cover 22 cooperate to seal the accommodating cavity 11, a part of the second connecting cover 22 extends into the accommodating cavity 11, wherein the handle 4 extends to the outer surface of the shell 1, and the handle 4 is arranged so as to apply a force to the second connecting cover 22. For example, in the case where the battery 6 needs to be detached, a pulling force may be applied to the handle 4 in advance, so that the second connection cover 22 and the first connection cover 21 are pushed out of the accommodating chamber 11, bringing the battery 6 out. And the first connection cover 21 and the second connection cover 22 are released from the engagement. After the replacement of the battery 6 is completed, the first connection cover 21 and the second connection cover 22 are fastened and fixed. At this time, pushing force is applied to the handle 4, so that the second connection cover 22 and the first connection cover 21 are pushed into the accommodating chamber 11, and the battery 6 is fixed.

In an alternative embodiment of the invention, referring to fig. 2, 3, 4 and 6, the hearing aid may further include a third buckle 5, where the third buckle 5 is fixed on the handle 4 or the second connection cover 22, the housing 1 is located in the area of the accommodating cavity 11 and a slot is formed, and the third buckle 5 and the slot cooperate to clamp the second connection cover 22 to the housing 1.

In the embodiment of the present invention, the third buckle 5 is configured to clamp the second connection cover 22 to the housing 1 located in the accommodating cavity 11. In one example, the third buckle 5 may be fixed to the handle 4, and the third buckle 5 and the handle 4 are integrally formed. In another example, the third buckle 5 may be fixed on the second connection cover 22, and the third buckle 5 and the second connection cover 22 are in an integral structure. Wherein the third catch 5 extends along the end of the second connecting cover 22 near the receiving chamber 11. After the battery 6 is fixed, the second connecting cover 22 and the first connecting cover 21 are rotated around the rotation joint between the first connecting cover 21 and the housing 1 through the handle 4, so that the third buckle 5 enters the accommodating cavity 11 and is deformed in pressing contact with the wall of the accommodating cavity 11. Until the third buckle 5 moves to the clamping groove, the third buckle 5 is embedded into the clamping groove by the deformation restoring force of the third buckle 5 to form clamping connection with the clamping groove, so that the second connecting cover 22 and the shell 1 are fixed.

In an example, in the case where the third buckle 5 is disposed on the handle 4, the third buckle 5 may further include an extension portion and a protrusion portion, the extension portion being connected at an angle to the protrusion portion, wherein the extension portion extends along the end portion of the second connection cover 22 near the accommodating cavity 11, and a pressure contact force generated by the protrusion portion contacting with the cavity wall of the accommodating cavity 11 acts on the extension portion, thereby deforming the extension portion. When the protruding portion moves to the clamping groove, the protruding portion is embedded in the clamping groove by means of deformation restoring force of the extending portion, so that the second connecting cover 22 and the shell 1 are fixed. When a force is applied to the handle 4, the third engagement piece 5 can be forced to come out of the housing chamber 11, and the engagement between the second connection cover 22 and the housing 1 can be released.

In an alternative embodiment of the invention, the hearing aid may further comprise a base fixed to the housing 1 and cooperating with the first and second connection covers 21, 22 so that the cross-sectional shape of the cavity wall of the battery receiving cavity 24 in the radial direction is annular.

In the embodiment of the invention, the base is located in the accommodating cavity 11, wherein the base is also used for further fixing the battery 6. For example, the cross-sectional shape of the end surface of the base adjacent to the battery 6 is a minor arc shape (which can also be understood as a circle of less than one-half). Thereby, the cross-sectional shape of the cell housing chamber 24 formed by the engagement of the base, the second connection cover 22, and the first connection cover 21 in the radial direction of the cell 6 is annular. Whereby the connection firmness of the battery 6 can be further improved. The base can be fixed on the shell 1 in an integrated mode, a threaded connection mode, a clamping mode and the like.

The outer surface of the first connecting cover 21, which is away from the accommodating chamber 11, and the outer surface of the second connecting cover 22, which is away from the accommodating chamber 11, are respectively kept flush with the outer surface of the housing 1. I.e. the contact area of the first connecting cover 21 and the housing 1 is smoothly transited, and the junction of the second connecting cover 22 and the housing 1 is smoothly transited. Thereby improving the user experience of the hearing aid.

In summary, the embodiment of the invention discloses a hearing aid, which may include a housing 1, a connection cover assembly 2 and a limit edge 3, wherein a receiving cavity 11 is formed on the housing 1, one end of the connection cover assembly 2 is rotatably connected to the housing 1, and the other end is detachably connected to the housing 1 to close the receiving cavity 11, wherein a battery receiving cavity 24 is provided on the connection cover assembly 2 located in the receiving cavity 11. The limiting edge 3 is located on the connecting cover assembly 2 to cooperate with the battery accommodating cavity 24 to limit the battery 6. Therefore, when the battery 6 is fixed through the connecting cover assembly 2, the battery 6 is rotationally carried out through the connecting cover assembly 2, and the operating space for dismounting the battery 6 is enlarged, so that the convenience of replacing the battery 6 can be improved.
