The second container 120 has a contour corresponding to the first opening 102, so that the second container 120 entirely covers the first opening 101.

The opening of the second recess 103 is facing upwards, in the same direction as the first opening 102. The bte hearing aid 10 can be placed in the second recess 103. The bte hearing aid 10 is shaped to fit the second recess 103 such that the bte hearing aid 10 is not prone to wobble when placed in the second recess 103.

As shown in fig. 3 and 5, in the present embodiment, the receiving case 100 for receiving a hearing device further includes a connecting shaft 140. The cover 130 is rotatably coupled to the first case 110 by a coupling shaft 140.

Specifically, as shown in fig. 4, the third groove 104 is formed recessed inward from the outer surface of the second side plate 113. The opening of the third groove 104 faces away from the fourth side plate 115.

As shown in fig. 1 to 3, a connection block 131 is fixed to one end of the cover 130. The connection block 131 is located in the third groove 104. The connecting shaft 140 sequentially passes through the first side plate 112, the side wall of the third groove 104, the connecting block 131 and the third side plate 114, so that the cover 130 can rotate relative to the first side plate 112 and the third side plate 114 and the side wall of the third groove 104 through the connecting shaft 140, that is, the cover 130 is rotatably connected with the first box 110 through the connecting shaft 140.

It is understood that in other embodiments, the cover 130 may be rotatably connected to the second container 120. The connection manner of the cover 130 and the second container 120 is similar to the connection manner of the cover 130 and the first container 110.

Since the second groove 103 is in communication with the first groove 101, a portion of the structure of the transmission assembly can pass through the first groove 101 into the second groove 103. The cover 130 can be switched between an open state and a closed state when rotated with respect to the first container 110. Referring to fig. 1, when the cover 130 is in the open state, the second recess 103 is exposed, and the bte hearing aid 10 can be placed in the second recess 103, and at this time, the portion of the transmission component located in the second recess 103 can be matched with the battery compartment cover 12 of the bte hearing aid 10. Then, the cover 130 is switched from the open state to the closed state by rotating the cover 130, in the process, the cover 130 drives the transmission component to move, so that the portion of the transmission component located in the second recess 103 can drive the battery compartment cover 12 of the bte hearing aid 10 to open. When the cover 130 is rotated to the closed state, the cover can cover the second container 120 and block the opening of the second groove 103, so that the bte hearing aid 10 can be accommodated in the second container 120.

Specifically, in the present embodiment, the connecting block 131 is in interference fit with the connecting shaft 140, and the cover 130 drives the connecting shaft 140 to rotate synchronously when rotating. Because the connecting shaft 140 is partially located in the first groove 101, and the transmission assembly is located in the first groove 101, the transmission assembly can be driven to rotate by the connecting shaft 140 partially located in the first groove 101, so that the transmission assembly drives the battery compartment cover 12 of the behind-the-ear hearing aid 10 to open.

It will be appreciated by those skilled in the art that the battery compartment cover 12 has a protrusion (not shown) which protrudes from the housing of the hearing aid main unit 11. The portion of the transmission assembly located in the second groove 103 drives the protrusion to rotate, and thus the battery compartment cover 12 of the behind-the-ear hearing aid 10 can be driven to open. The specific structure of the bte hearing aid 10 is conventional and will not be described in detail herein.

In the storage box 100 for storing the hearing device, since the second groove 103 is communicated with the first groove 101, part of the structure of the transmission assembly can pass through the first groove 101 and enter the second groove 103. When the cover 130 is in the open state, the second recess 103 is exposed, so that the bte hearing aid 10 can be placed in the second recess 103, and at this time, the portion of the transmission component located in the second recess 103 can be matched with the battery compartment cover 12 of the bte hearing aid 10. In the process of switching the cover 130 from the open state to the closed state, the cover 130 can drive the transmission component to move, so that the portion of the transmission component located in the second groove 103 can drive the battery compartment cover 12 of the behind-the-ear hearing aid 10 to open. Above-mentioned process has realized taking in back of the ear formula audiphone 10 in the receiver 100 that is used for taking in the hearing device, and the battery storehouse lid 12 of back of the ear formula audiphone 10 is automatic to open to make things convenient for back of the ear formula audiphone 10 auto-power-off to shut down, save battery power. In addition, since the operation of turning off the behind-the-ear hearing aid 10 is combined with the operation of turning off the storage case 100 for storing the hearing device, the operation difficulty and the operation steps for turning off the behind-the-ear hearing aid 10 are reduced, which is convenient for the elderly to use.

It should be noted that, although the present embodiment is described only by taking the example in which the hearing device is the behind-the-ear hearing aid 10, the hearing device of the present application is not limited to the behind-the-ear hearing aid 10. For example, the hearing device may also be an in-the-ear hearing aid, a box hearing aid, or other type of hearing aid. Furthermore, the hearing device may also be an earphone, such as a headset, a neckband, a wireless earphone, etc. The present embodiment is not limited to a specific type of hearing device, as long as the hearing device is configured to be placed in the receiving case 100 for receiving the hearing device, and the battery compartment cover 12 of the hearing device can be automatically opened through the above-described process.

As shown in fig. 1, in the present embodiment, the behind-the-ear hearing aid 10 includes two hearing aid hosts 11, and the two hearing aid hosts 11 are respectively adapted to perform hearing aid for left and right ears. When the behind-the-ear hearing aid 10 is stored in the storage case 100 for storing the hearing device, the transmission unit can open the battery compartment covers 12 of the two hearing aid main units 11 at the same time, so that the two hearing aid main units 11 are turned off at the same time.

It is to be understood that in other embodiments, the bte hearing aid 10 may comprise only one hearing aid host 11, and the bte hearing aid 10 with one hearing aid host 11 is suitable for single-ear hearing aid. When the behind-the-ear hearing aid 10 is stored in the storage case 100 for storing the hearing device, the transmission unit opens only the battery compartment cover 12 of one hearing aid main unit 11, and shuts down the one hearing aid main unit 11.

In one embodiment, the transmission assembly comprises: a gear assembly and a toggle assembly. Part of the structure of the dial assembly is able to pass through the first recess 101 and into the second recess 103. In the process of switching the cover 130 between the open state and the closed state, the connecting shaft 140 can drive the gear assembly to rotate, the gear assembly can drive the shifting assembly to rotate, and the part of the shifting assembly located in the second groove 103 can drive the battery compartment cover 12 to rotate.

Specifically, as mentioned above, the connecting shaft 140 is at least partially located in the first groove 101, and since the transmission assembly is located in the first groove 101, the portion of the connecting shaft 140 located in the first groove 101 facilitates to drive the transmission assembly to move.

Referring to fig. 1, a bottom wall of the second groove 102 is provided with a communication opening 105. Part of the structure of the dial assembly can protrude through the communication opening 105 into the second recess 102.

The first bevel gear 151 is coaxially connected with the connecting shaft 140. The second bevel gear 152 is engaged with the first bevel gear 151. The rotation axis of the second bevel gear 152 is perpendicular to the rotation axis of the first bevel gear 151, and the second bevel gear 152 is used for driving the spur gear set to rotate.

Specifically, the first bevel gear 151 is sleeved on the connecting shaft 140 and is in interference fit with the connecting shaft 140, so that the connecting shaft 140 can drive the first bevel gear 151 to rotate synchronously when rotating. Referring to fig. 4, the transmission assembly further includes a first rotating shaft 181, and the first rotating shaft 181 is disposed on the bottom plate 111. The second bevel gear 152 is sleeved on the first rotating shaft 181. When the first bevel gear 151 rotates the second bevel gear 152, the second bevel gear 152 can rotate around the first rotating shaft 181.

Because the first bevel gear 151 is coaxially connected with the connecting shaft 140, the second bevel gear 152 drives the spur gear set to rotate, and the rotation axis of the second bevel gear 152 is perpendicular to the rotation axis of the first bevel gear 151, the rotation axis of the spur gear set can be perpendicular to the rotation axis of the connecting shaft 140 through the steering action of the second bevel gear 152 and the first bevel gear 151.

As shown in fig. 3, the rotation axis of the connecting shaft 140 is along the horizontal direction, and the rotation axis of the spur gear set is along the vertical direction, so that the rotation axis of the toggle assembly is along the vertical direction, and the battery compartment cover 12 can be driven to open when the toggle assembly rotates.

Referring to fig. 3, in an embodiment, the spur gear set includes: a first spur gear 171, a second spur gear 172, and a third spur gear 173. The first straight gear 171 is coaxially connected to the second bevel gear 152. The second spur gear 172 is engaged with the first spur gear 171 and the third spur gear 173, respectively. The toggle assembly includes a first toggle portion 160 a. A portion of the first toggle part 160a is configured to pass through the first recess 101 and enter the second recess 103. The third spur gear 173 can drive the first toggle part 160a to rotate, so that the portion of the first toggle part 160a entering the second groove 103 can drive the battery compartment cover 12 to open.

Specifically, as shown in fig. 3, the first straight gear 171 is sleeved on the first rotating shaft 181 and located between the second bevel gear 152 and the bottom plate 111. The first spur gear 171 is provided with a first pin hole (not shown), and the second spur gear 152 is provided with a second pin hole (not shown). Referring to fig. 6, the transmission assembly further includes a first cylindrical pin 182, and the first straight gear 171 and the second bevel gear 152 can be coaxially connected by interference fit of the first cylindrical pin 182 with the first pin hole and the second pin hole, respectively.

Referring to fig. 4, the driving assembly further includes a second shaft 183, and the second shaft 183 is disposed on the bottom plate 111. The second spur gear 172 is sleeved on the second rotating shaft 183. When the first spur gear 171 rotates the second spur gear 172, the second spur gear 172 rotates around the second rotation shaft 183.

The transmission assembly further includes a third shaft 184. The third shaft 184 is rotatably connected to the base plate 111. The third rotation shaft 184 is coaxially connected to the third spur gear 173. Specifically, the third spur gear 173 is sleeved on the third rotating shaft 184 and is connected to the third rotating shaft 184 in a key manner, so that the third spur gear 173 and the third rotating shaft 184 can be coaxially connected.

When the second bevel gear 152 rotates, the first spur gear 171 rotates synchronously, the first spur gear 171 drives the second spur gear 172 to rotate, the second spur gear 172 drives the third spur gear 173 to rotate, the third spur gear 173 drives the first shifting portion 160a to rotate, and a portion of the first shifting portion 160a entering the second groove 103 drives the battery compartment cover 12 to rotate, so as to open the battery compartment cover 12.

As shown in fig. 3, the second spur gear 172 reverses the direction between the first spur gear 171 and the third spur gear 173, so that the rotation direction of the third spur gear 173 is opposite to the rotation direction of the first spur gear 171, which makes the third spur gear 173 drives the first shifting portion 160a to rotate in the direction of opening the battery compartment cover 12 during the closing process of the cover 110.

It is understood that in other embodiments, the second spur gear 172 may not be provided, but the third spur gear 173 may be directly engaged with the first spur gear 171, in which case, by adjusting the installation direction of the first bevel gear 151, the rotation direction of the third spur gear 173 may also be adjusted, and the third spur gear 173 drives the first toggle part 160a to rotate in the direction of opening the battery compartment cover 12 during the closing process of the cover 110.

Referring to fig. 3, in an embodiment, an outer diameter of the second spur gear 172 is smaller than an outer diameter of the third spur gear 173.

Specifically, by providing the second spur gear 172 between the first spur gear 171 and the third spur gear 173, the position of the third spur gear 173 can be adjusted to the middle area of the first groove 101, and the third spur gear 173 is prevented from interfering with the first side plate 112. Also, since the outer diameter of the second spur gear 172 is small, the second spur gear 172 does not interfere with the first side plate 112.

It is understood that in other embodiments, the second spur gear 172 may not be provided, and the third spur gear 173 may be directly engaged with the first spur gear 171, in which case, by increasing the volume of the first groove 101, the third spur gear 173 may be prevented from interfering with the first side plate 112.

Referring to fig. 3, in an embodiment, the spur gear set further includes a fourth spur gear 174. The fourth spur gear 174 is engaged with the third spur gear 173. The toggle assembly further includes a second toggle portion 160 b. Part of the structure of the second toggle part 160b can pass through the first recess 101 into the second recess 103. When the third spur gear 173 rotates, the fourth spur gear 174 is driven to rotate, and the fourth spur gear 174 can drive the second shifting portion 160b to rotate, so that the portion of the second shifting portion 160b entering the second groove 103 can drive the battery compartment cover 12 to open.

Specifically, as described above, in the present embodiment, the behind-the-ear hearing aid 100 includes two hearing aid main units 11, each hearing aid main unit 11 has one battery compartment cover 12, the first toggle part 160a is used for toggling one of the battery compartment covers 12, and the second toggle part 160b is used for toggling the other battery compartment cover 12.

When the third spur gear 173 rotates, the first toggle portion 160 is driven to toggle one of the battery compartment covers 12 to open. And, the third spur gear 173 drives the fourth spur gear 174 to rotate, and the fourth spur gear 174 drives the second toggle part 160b to rotate, so that the portion of the second toggle part 160b entering the second groove 103 drives another battery compartment cover 12 to open.

It is understood that in other embodiments, when the bte hearing aid 100 only includes one hearing aid main unit 11, only one battery compartment cover 12 needs to be opened, the spur gear set may not include the fourth spur gear 174, and the one battery compartment cover 12 can be opened by driving the first toggle portion 160a through the third spur gear 173.

Referring to fig. 3, in an embodiment, each toggle portion includes a toggle rod 161 and a toggle finger 162, one end of the toggle rod 161 is connected to the gear assembly, and the other end is connected to the toggle finger 162.

In particular, it is to be understood that when the bte hearing aid 100 comprises only one hearing aid host unit 11, the bte hearing aid 100 comprises at least the first toggle part 160 a. When the bte hearing aid 10 comprises two hearing aid hosts 11, the bte hearing aid 100 comprises both the first and

second dials

160a, 160 b.

In this embodiment, the bte hearing aid 100 includes both the first toggle 160a and the second toggle 160 b. One end of the tap lever 161 of the first tap portion 160a is connected to the third spur gear 173, and the other end is connected to the tap finger 162. Referring to fig. 1, the finger 162 passes through the communication opening 105 and enters the second groove 103. When the third spur gear 173 rotates during the closing of the cover 130, the shifting rod 161 of the first shifting portion 160a is driven to rotate, the shifting rod 161 drives the corresponding shifting finger 162 to rotate, and the shifting finger 162 pushes one of the battery compartment covers 12 to open.

Similarly, one end of the toggle rod 161 of the second toggle portion 160b is connected to the fourth spur gear 174, and the other end is connected to the toggle finger 162, and the toggle finger 162 passes through the communication opening 105 and enters the second groove 103. When the fourth spur gear 174 rotates during the closing of the cover 130, the shifting rod 161 of the second shifting portion 160b is driven, the shifting rod 161 drives the corresponding shifting finger 162, and the shifting finger 162 pushes the corresponding other battery compartment cover 12 to open.

Since the third spur gear 173 and the fourth spur gear 174 rotate simultaneously during the closing of the cover 130, the battery compartment covers 12 of the two hearing aid main units 11 can be opened simultaneously, and the two hearing aid main units 11 can be shut down simultaneously.

In one embodiment, the cover 130 can drive the transmission assembly to move during the process of switching from the closed state to the open state, and part of the transmission assembly can drive the battery compartment cover 12 to close.

Specifically, as shown in fig. 3, in the present embodiment, two fingers 162 are connected to the other end of each tap lever 161, and the two fingers 162 are spaced apart from each other. The two fingers 162 simultaneously pass through the communication opening 105 into the second groove 102.

When the cover 110 is in the open position and the bte hearing aid 10 is placed in the second recess 103, the protrusion of the battery compartment cover 12 can fall between the two fingers 162. Therefore, in the process of switching the cover 130 from the open state to the closed state, one of the fingers 162 may drive the corresponding battery compartment cover 12 to open, and the behind-the-ear hearing aid 100 may be automatically turned off. When the cover 130 is switched from the closed state to the open state, the other finger 162 may drive the battery compartment cover 12 to automatically close, so that the behind-the-ear hearing aid 100 can be automatically turned on. Therefore, the opening of the cover 130 corresponds to the turning on of the bte hearing aid 100, and the closing of the cover 130 corresponds to the turning off of the bte hearing aid 100, thereby facilitating the turning on and off of the bte hearing aid 100.

It can be understood that the movement process of the transmission assembly during the process of switching the cover 130 from the closed state to the open state is opposite to the movement process of the transmission assembly during the process of switching the cover 130 from the open state to the closed state, and therefore, the description thereof is omitted.

Referring to fig. 4 in conjunction with fig. 3, in an embodiment, a first boss 186 is fixed at one end of the third shaft 184. The first toggle part 160a has a first fitting hole (not shown) that is fitted with the first boss 186. The cross-sectional profile of the first boss 186 is non-circular.

Specifically, as shown in fig. 4, in the present embodiment, the cross-sectional profile of the first boss 186 is square, so that when the first toggle part 160a is engaged with the first boss 186, the first toggle part 160a can rotate synchronously with the first boss 186. Specifically, when the third spur gear 173 drives the third rotating shaft 184 to rotate synchronously, the third rotating shaft 184 drives the first boss 186 to rotate synchronously, and the first boss 186 drives the first shifting portion 160a to rotate synchronously, so as to conveniently drive the first shifting portion 160a to rotate.

It is understood that the cross-section of the first boss 186 may also be triangular, pentagonal, or other irregular shapes, etc.

Referring to fig. 4 in conjunction with fig. 3, in an embodiment, a second boss 187 is fixed at one end of the fourth shaft 185. The second dial portion 160b has a second fitting hole (not shown) to be fitted with the second boss 187. The cross-sectional profile of the second bosses 187 is non-circular.

Specifically, like the first boss 186, when the fourth spur gear 174 drives the fourth rotation shaft 185 to rotate synchronously, the fourth rotation shaft 185 drives the second boss 187 to rotate synchronously, and the second boss 187 drives the second shifting portion 160b to rotate synchronously, so as to conveniently drive the second shifting portion 160b to rotate.

The second bosses 187 may also be triangular, pentagonal, or otherwise irregular in cross-section, etc.

Referring to fig. 4, in an embodiment, a third boss 188 is further disposed between the third spur gear 173 and the bottom plate 111. The third boss 188 is fixedly connected to the base plate 111. The third boss 188 is sleeved on the third shaft 184.

Specifically, since the third boss 188 is located between the third spur gear 173 and the base plate 111, the lower end surface of the third spur gear 173 is in contact with the third boss 188, not the base plate 111, so that the contact area between the third spur gear 173 and the base plate 111 can be reduced, and thus the frictional resistance when the third spur gear 173 rotates can be reduced.

Meanwhile, the third spur gear 173 is located between the third boss 188 and the first dial part 160a, and thus, the third boss 188 and the first dial part 160a may define an axial position of the third spur gear 173.

Referring to fig. 4, in an embodiment, a fourth boss 189 is further disposed between the fourth spur gear 174 and the base plate 111. The fourth boss 189 is fixedly coupled to the base plate 111. The fourth boss 189 is sleeved on the fourth shaft 185.

Specifically, like the third boss 188, since the fourth boss 189 is located between the fourth spur gear 174 and the base plate 111, a contact area between the fourth spur gear 174 and the base plate 111 may be reduced, and thus frictional resistance when the fourth spur gear 174 rotates may be reduced. Meanwhile, the fourth boss 189 and the second toggle part 160b may define an axial position of the fourth spur gear 174.

Referring to fig. 3, in one embodiment, the receiving case 100 for receiving a hearing device further includes a bolt 191. A threaded hole is formed in the second rotating shaft 183. The bolt 191 is fitted into the threaded hole. The second spur gear 172 is located between the head of the bolt 191 and the bottom plate 111, so that the head of the bolt and the bottom plate 111 can define the axial position of the second spur gear 172.

Referring to fig. 4, in an embodiment, a fifth boss 190 is further disposed between the second spur gear 172 and the bottom plate 111. The fifth boss 190 is fixedly connected to the base plate 111. The fifth boss 190 is sleeved on the second shaft 183.

Specifically, like the third boss 188, since the fifth boss 190 is located between the second spur gear 172 and the base plate 111, a contact area between the second spur gear 172 and the base plate 111 may be reduced, and thus frictional resistance when the second spur gear 172 rotates may be reduced.

Meanwhile, it is understood that the second spur gear 172 is located between the head of the bolt 191 and the fifth boss 190, so that the axial position of the second spur gear 174 may be defined.
