Definitions

  • the present invention relates to a battery door for a hearing device and a hearing device comprising a battery door.
  • a focus in the hearing aid industry is to make hearing aids smaller and more discrete for the benefit of the user and thus a design which can decrease the size of the hearing aid is of importance. Further, it is of great interest from a cost perspective that designs are easy and cheap to manufacture.
  • a button battery is used in a hearing device and traditionally a battery door of a hearing aid has been fitted with a locking mechanism, e.g. operated by a small slider or relying on a spring effect of the material, leading to bulky hearing devices a complex manufacturing process and/or high failure rate of the locking mechanism.
  • a battery door for a hearing device comprising a body with at least one pivoting element for coupling the battery door to a hearing device housing such that the battery door is configured to pivot about a pivoting axis.
  • the body has a bottom part and a sidewall.
  • the bottom part has a first bottom surface and the sidewall has a first wall surface, the first wall surface comprising contact points for supporting a battery with a battery radius, wherein the first bottom surface and the first wall surface at least partly defines a battery compartment with a battery axis and contact points of the first wall surface arranged at a battery distance from the battery axis.
  • a center axis perpendicularly crosses the pivoting axis and crosses the battery axis.
  • the battery door further comprises a first locking element and a second locking element.
  • the first locking element may be arranged in the bottom part of the body and/or the second locking element may be arranged in the bottom part of the body.
  • a hearing device comprising a housing and a battery door as described is disclosed, wherein the hearing device comprises at least one engagement member configured to engage with the first and second locking element of the battery door, when the battery door is in a first and second position, respectively.
  • the disclosed battery door is advantageous in that it decreases the space needed for the locking mechanism, thus facilitating a small hearing device and a small battery door. Furthermore, due to a simplification of the locking mechanism, a battery door that is simple to manufacture and has reduced requirements to material quality is provided, resulting in reduced costs and reduced failure rates.
  • a positive angle between the center axis and an axis is an angle from the center axis to the respective axis in the intended closing direction of the battery door.
  • a negative angle between the center axis and an axis is an angle from the center axis to the respective axis in the intended opening direction of the battery door.
  • the battery distance is measured perpendicular to the battery axis.
  • the body has a first end and a second end.
  • the battery is inserted into the battery compartment through an opening in the first end along the battery axis.
  • the bottom part of the body is the part of the body between the first bottom surface and the second end.
  • the first locking element may be arranged in the bottom part at a first distance from the battery axis.
  • the first distance may be less than the battery distance.
  • the second locking element may be arranged in the bottom part at a second distance from the battery axis.
  • the second distance may be less than the battery distance.
  • the first distance and the second distance are both less than battery distance.
  • the second distance may be less than the first distance.
  • the second distance may be larger than the first distance.
  • the first locking element may be arranged on a first straight axis perpendicularly crossing the pivoting axis, wherein a first angle between the center axis and the first axis may be in the range from -20° to 20°.
  • the first angle may be in the range from -10° to 10°.
  • the first angle may be larger than 0°.
  • the second locking element may be arranged on a second straight axis perpendicularly crossing the pivoting axis, wherein a second angle between the center axis and the second axis may be in the range from -20° to 20°.
  • the second angle may be in the range from -10° to 10°.
  • the second angle may be less than 0°.
  • the smallest angle between the first axis and the second axis is denoted the third angle.
  • the numerical value of the third angle may be in the range from 5° to 30°, e.g. in the range from 5° to 20°. In an exemplary battery door, the numerical value of the third angle is in the range from 6° to 15°, e.g. 8°.
  • the third angle must be large enough to facilitate a tactile difference between the first and second positions. On the other hand, a small angle may be desired to facilitate a compact design and prevent the battery door from being too open in a first position.
  • the locking elements may comprise one or more recesses in the bottom surface.
  • a recess may extend in any direction and may be in one direction in the first locking element and another in the second locking element.
  • the locking element(s) may each comprise one or more recesses extending radially inward towards the battery axis. Thereby a compact design is facilitated preventing the locking mechanism from taking up excess space.
  • the bottom part may have a first cutout section.
  • the first cutout section may extend to a second wall surface or outer surface of the sidewall, such that an electrical connector placed inside the housing of the hearing aid engages with the bottom of a battery placed in the battery door when a user closes the battery door by pivoting the battery door in the closing direction.
  • the bottom part may also have a second cutout section.
  • the second cutout may be located such that the bottom part comprises an arc-shaped bridge element.
  • the first locking element and/or the second locking element may be formed on an outer edge of the bridge element.
  • the thickness of the bridge element is to be determined by the specific material in use and should be thin enough to provide enough flexibility for an engagement member of the hearing aid to engage with the locking elements and thick enough to prevent the bridge element from breaking due to wear and tear.
  • the second cutout section may be an open cutout forming at least a first arm element in the bottom part.
  • the first arm element may point in the opening or the closing direction.
  • the second cutout may form a second arm element in the bottom part.
  • the first locking element and the second locking element may be formed in the first arm element.
  • the first locking element is formed in the first arm element and the second locking element is formed in the second arm element.
  • An arm element facilitates greater flexibility, but also dictates a higher demand to strength of the material.
  • one of the locking elements e.g. the first locking element, may be located on the first arm element while the other locking element, e.g. the second locking element, is formed as part of a cutout.
  • Fig. 1 shows a top view of an exemplary battery door 10 for a hearing device.
  • the battery door 10 comprises a body 12 with at least one pivoting element 14 for coupling the battery door 10 to the hearing device such that the battery door 10 is configured to pivot about a pivoting axis 32.
  • the body may comprise first and second pivoting elements with bores for accomodating a rod or pin to pivot the body 12 about the rod/pin forming the pivoting axis 32.
  • the body 12 has a bottom part 16 and a sidewall 18, the bottom part 16 having a first bottom surface 20 and the sidewall having a first wall surface 22 and a second wall surface 24.
  • the first wall surface comprises contact points and/or contact surfaces (26) for supporting a battery 28 with a battery radius R bat (see Fig.
  • the first bottom surface 20 and the first wall surface 22 at least partly defines a battery compartment 30 with a battery axis 34 and contact points of the first wall surface 22 arranged at a battery distance R 1 (see Fig. 3 ) from the battery axis 34.
  • the battery door 10 comprises a first locking element 38 formed as a first recess extending radially inward (perpendicular to the battery axis) in the bottom part 16.
  • the battery door 10 comprises a second locking element 42 formed as a second recess extending radially inward (perpendicular to the battery axis) in the bottom part 16.
  • the bottom part 16 has a first cutout 50 extending to the second wall surface 24, such that an electrical connector arranged inside the housing of the hearing aid is connectable to a bottom of a battery placed in the battery door by pivoting the battery door about the pivot axis 32.
  • the battery bottom of a battery is the battery surface facing the bottom part.
  • the bottom part 16 has a second cutout 52 forming a bridge element 53 in the bottom part, and wherein the first locking element 38 and the second locking element 42 are formed on an outer edge of the bridge element.
  • the bridge element 53 is flexible and allows the bridge element 53 with the first and second locking elements to move during opening and closing of the battery door, such that the first and second locking elements can engage with engagement member(s) of a hearing device housing in first and second positions, respectively.
  • the user opens the battery door 10 by pushing the tip of the handle element 54 in the opening direction 48. Closing the battery door is achieved by pushing the body 12 or the handle element 54 in the closing direction 46.
