[0053] A hearing aid is a common tool for improving hearing impairment. Nowadays, the main user group of the hearing aid is the elderly, in order to prevent the hearing aid from being lost, the hearing aid is usually equipped with an anti-lost rope. The anti-lost rope is detachably connected with the hearing aid. When the hearing aid is used, the user can connect the anti-lost rope and the hearing aid. If the hearing aid needs to be temporarily taken off during use, the hearing aid can be hung around the neck or wrist through the anti-lost rope to avoid losing the hearing aid. After the use of the hearing aid is completed, the user needs to place the hearing aid in the charging box for charging to restore the endurance of the hearing aid. However, the charging box of the current hearing aid is not compatible with the anti-lost rope. This makes it necessary to first detach the anti-lost rope from the hearing aid when the hearing aid needs to be charged using the charging box, resulting in a relatively cumbersome charging process of the hearing aid. In addition, since the charging box is not compatible with the anti-lost rope, the user needs to store the hearing aid and the anti-lost rope separately when carrying the hearing aid outside, which not only increases the storage difficulty, but also makes the anti-lost rope easy to be lost.

[0054] The hearing aid assembly provided by the embodiments of the present disclosure comprises a charging box, a hearing aid and an anti-lost rope. Figure 1 As shown in the figure, the hearing aid assembly comprises a charging box 1, a hearing aid 2 and an anti-lost rope 3.

[0055] The charging box 1 comprises a box body 11 and a connecting piece 12. The connecting piece 12 is located in the box body 11 and connected with the box body 11. The connecting piece 12 has a containing groove 121 and a connecting through groove 122. The containing groove 121 is compatible with the shape and size of the hearing aid 2. The connecting through groove 122 is in communication with the containing groove 121. The box body 11 has an avoiding hole 101 penetrating the inner wall and the outer wall. The avoiding hole 101 is in communication with the connecting through groove 122. The hearing aid 2 is located in the containing groove 121. The end of the anti-lost rope 3 passes through the avoiding hole 101 and the connecting through groove 122 in sequence and is connected with the hearing aid 2.

[0056] In this way, the box body 11 has the avoiding hole 101 penetrating the inner wall and the outer wall. The connecting piece 12 has the connecting through groove 122. The end of the anti-lost rope 3 can pass through the avoiding hole 101 and the connecting through groove 122 in sequence and be connected with the hearing aid 2. That is, the charging box 1 is compatible with the anti-lost rope 3. In the case that the hearing aid 2 is placed in the charging box 1, the anti-lost rope 3 can still be connected with the hearing aid 2. Therefore, the user does not need to detach the anti-lost rope when charging the hearing aid 2 using the charging box 1, which simplifies the charging process of the hearing aid.

[0057] At the same time, since the anti-lost rope 3 can still be connected with the hearing aid 2 in the case that the hearing aid 2 is placed in the charging box 1, the user does not need to store the hearing aid and the anti-lost rope separately when carrying the hearing aid outside, which reduces the storage difficulty and also avoids the anti-lost rope from being lost.

[0058] In some possible embodiments, the hearing aid assembly comprises two hearing aids 2.

[0059] As shown in Figure 1 The connecting piece 12 has two accommodating grooves 121 and two connecting through-slots 122, each connecting through-slot 122 corresponds to one accommodating groove 121. The box body 11 has two avoiding holes 101, each avoiding hole 101 corresponds to one connecting through-slot 122.

[0060] Further, the two ends of the anti-lost rope 3 pass through one avoiding hole 101 and one connecting through-slot 122 respectively, and are connected with one hearing aid 2 respectively.

[0061] In this way, after the two ends of the anti-lost rope 3 pass through one avoiding hole 101 and one connecting through-slot 122 respectively and are connected with the hearing aid 2, a ring structure can be formed between the anti-lost rope 3 and the charging box 1, which facilitates the user to hold the hearing aid assembly.

[0062] In some possible embodiments, the box body 11 includes a base 111 and an upper cover 112.

[0063] As shown in Figure 1 The box body 11 includes a base 111 and an upper cover 112. The base 111 is open at one end, and the connecting piece 12 is located at the open end of the base 111 and connected with the base 111. The upper cover 112 is connected with the base 111.

[0064] Specifically, the base 111 and the upper cover 112 can each have a structure similar to a spherical cap, and the base 111 and the upper cover 112 are adapted to each other.

[0065] The connecting piece 12 is located at the open end of the base 111 and at least partially located in the base 111, and is connected with the base 111. The upper wall surface of the connecting piece 12 has the accommodating grooves 121 and the connecting through-slots 122. In the case that the connecting piece 12 extends into the base 111 to different depths, the forming mode of the avoiding holes 101 will change accordingly.

[0066] In an example, the upper cover 112 and / or the base 111 has the avoiding holes 101.

[0067] In this example, the base 111 has the avoiding hole 101 when the connecting piece 12 is inserted into the base 111 to a deep position so that the upper wall surface of the connecting piece 12 is located inside the base 111. The upper cover 112 has the avoiding hole 101 when the connecting piece 12 is inserted into the base 111 to a shallow position so that the groove bottom of the accommodating groove 121 and the connecting through groove 122 is located outside the base 111. The upper cover 112 has a partial avoiding hole 101 and the base 111 also has a partial avoiding hole 101 when the connecting piece 12 is inserted into the base 111 to a moderate position so that the upper wall surface of the connecting piece 12 is located outside the base 111 and the groove bottom of the accommodating groove 121 and the connecting through groove 122 is located inside the base 111, and the two partial avoiding holes 101 are arranged to form a complete avoiding hole.

[0068] In some possible embodiments, the connection between the anti-loss rope 3 and the hearing aid 2 is detachable connection.

[0069] In one example, the anti-loss rope 3 is connected with the hearing aid 2 by clamping.

[0070] As shown in Figure 2 , the outer wall of the hearing aid 2 has a clamping groove 201, and a connecting column 202 is arranged in the clamping groove 201. The anti-loss rope 3 includes a rope body 31 and a clamping hook 32, the clamping hook 32 is fixedly connected with the end of the rope body 31 and detachably connected with the connecting column 202.

[0071] Specifically, the clamping groove 201 has two opposite wall surfaces which can be parallel to each other, the connecting column 202 can have a cylindrical structure, and the two ends of the connecting column 202 are connected with the two wall surfaces respectively, and the outer wall of the connecting column 202 has a gap with the bottom surface and the side wall of the clamping groove 201. The clamping hook 32 includes a clamping part and a connecting part, the clamping part is used to extend into the clamping groove 201 and clamp with the connecting column 202, and the connecting part is used to connect with the end of the rope body 31.

[0072] Further, the outer diameter of the connecting column 202 is smaller than the inner diameter of the clamping part of the clamping hook 32, and the outer diameter of the clamping part is smaller than the size of the gap, so that the clamping hook 32 can be smoothly extended into the clamping groove 201 and clamped with the connecting column 202. The connecting manner between the connecting part and the end of the rope body 31 can be adhesive connection, which is not limited in the embodiments of the present disclosure.

[0073] In this example, the shape and size of the connecting through groove 122 on the connecting piece 12 are matched with the anti-loss rope 3.

[0074] As shown in Figure 2 , the anti-loss rope 3 includes the rope body 31 and the clamping hook 32 connected with each other, and the outer diameter of the clamping hook 32 is greater than the outer diameter of the rope body 31. Correspondingly, as shown in Figure 3The connecting channel 122 comprises a first part 1221 and a second part 1222. The first part 1221 is in communication with the accommodating groove 121, and the first part 1221 is adapted to the shape and size of the hook 32. The second part 1222 is in communication with the first part 1221 and the avoiding hole 101 respectively, and the second part 1222 is adapted to the shape and size of the rope 31.

[0075] Optionally, the first part 1221 and the second part 1222, and the first part 1221 and the accommodating groove 121 can be smoothly transitioned.

[0076] It can be understood that the above-mentioned "adapted to" means that the hook 32 can be smoothly assembled into the first part 1221 of the connecting channel 122, and the hook 32 will not shake greatly after being assembled into the first part 1221 of the connecting channel 122. Similarly, the rope 31 can be smoothly assembled into the second part 1222 of the connecting channel 122, and the rope 31 will not shake greatly after being assembled into the second part 1222 of the connecting channel 122.

[0077] In an example, the anti-lost rope 3 is threadedly connected with the hearing aid 2.

[0078] In implementation, the outer wall of the hearing aid 2 can even have a threaded hole, which has the same extension direction as the avoiding hole 101, and the threaded hole is provided with an internal thread. The anti-lost rope 3 comprises a connecting stud and a rope body, the outer wall of the stud is provided with an external thread which is adapted to the internal thread, the stud is fixedly connected with the end of the rope body, and the anti-lost rope 3 is detachably connected through the cooperation between the stud and the threaded hole.

[0079] It can be understood that the above-mentioned internal thread and external thread are adapted to each other, which means that the parameters such as tooth type and pitch of the internal thread and the external thread are adapted to each other.

[0080] In some possible embodiments, the first side of the base 111 is hingedly connected with the first side of the upper cover 112, and the second side of the base 111 is detachably connected with the second side of the upper cover 112.

[0081] Specifically, as shown in Figure 4 the first side of the base 111 is provided with a connecting seat, and the first side of the upper cover 112 is provided with a connecting head which is adapted to the connecting seat, and the connecting head and the connecting seat are hingedly connected through a hinge shaft 100 to realize the rotational connection of the base 111 and the upper cover 112.

[0082] As shown in Figure 5As shown, the box body 11 further comprises a first clamping structure 113 and a second clamping structure 114. The second side of the base 111 can be provided with a receiving hole 1111, the first clamping structure 113 is located in the receiving hole 1111 and is in sliding connection with the receiving hole 1111 along the axial direction of the receiving hole 1111, and the second clamping structure 114 is located on the second side of the upper cover and is connected with the upper cover 112.

[0083] Further, the first clamping structure 113 comprises a push button and a first clamping piece connected with each other. The push button is in sliding connection with the receiving hole 1111 provided on the outer wall of the base 111, and the first clamping piece is connected with one end of the push button close to the first side of the base 111. The first clamping piece can move in the axial direction of the receiving hole 1111 to combine or separate from the second clamping structure 114 under the action of the push button, so as to realize the clamping or separation between the base 111 and the upper cover 112.

[0084] In implementation, when the user needs to use the charging box 1 to charge the hearing aid 2, an action force can be applied to the push button towards the hinge shaft 100, so that the first clamping structure 113 and the second clamping structure 114 are separated, and the base 111 and the upper cover 112 are unlocked. Then, the upper cover 112 is rotated to separate the base 111 from the upper cover 112, and then the hearing aid 2 is placed on the connecting piece 12 for charging.

[0085] Optionally, a torsional spring can be sleeved on the outer wall of the hinge shaft 100, and two pins of the torsional spring are connected with the upper cover 112 and the base 111 respectively.

[0086] In this way, when the user needs to use the charging box 1 to charge the hearing aid 2, an action force can be applied to the push button towards the hinge shaft 100, so that the first clamping structure 113 and the second clamping structure 114 are separated, and the upper cover 112 and the base 111 can be directly pushed apart by the elastic force of the torsional spring, without the need for the user to manually rotate the upper cover 112, thereby improving the convenience of charging.

[0087] In an example, as shown in Figure 1 , the outer wall of the base 111 is provided with a charging jack 200.

[0088] As shown in Figure 1 , the charging jack 200 penetrates the inner wall and the outer wall of the base 111 and is electrically connected with the battery 400 through the circuit board 300. The charging jack 200 can be arranged below the hinge shaft 100. In this way, when the charging jack 200 is connected with the charging line, it will not block the front of the hearing aid charging box, and the convenience of connecting the charging line of the hearing aid charging box can be improved.

[0089] In some possible embodiments, as shown in Figure 3As shown, the hearing aid assembly further comprises a scratch-proof pad 4 fixed to the groove wall of the accommodating groove 121.

[0090] In this way, the hearing aid 2 can avoid hard contact with the groove wall of the accommodating groove 121, thereby preventing the hearing aid 2 from being scratched.

[0091] The technical solutions provided by the embodiments of the present disclosure have at least the following beneficial effects:

[0092] The hearing aid assembly provided by the embodiments of the present disclosure comprises a charging box 1, which comprises a box body 11 and a connecting piece 12. The connecting piece 12 is located in the box body 11 and connected to the box body 11. The connecting piece 12 has an accommodating groove 121 and a connecting through groove 122. The accommodating groove 121 is matched in shape and size with the hearing aid 2. The connecting through groove 122 is in communication with the accommodating groove 121. The box body 11 has an avoiding hole 101 penetrating the inner wall and the outer wall. The avoiding hole 101 is in communication with the connecting through groove 122. The hearing aid 2 is located in the accommodating groove 121. The end of the anti-lost rope 3 passes through the avoiding hole 101 and the connecting through groove 122 in sequence and is connected to the hearing aid 2. In this way, the box body 11 has the avoiding hole 101 penetrating the inner wall and the outer wall. The connecting piece 12 has the connecting through groove 122. The end of the anti-lost rope 3 can pass through the avoiding hole 101 and the connecting through groove 122 in sequence and be connected to the hearing aid 2. That is, the charging box 1 is matched with the anti-lost rope 3. In the case that the hearing aid 2 is placed in the charging box 1, the anti-lost rope 3 can still be connected to the hearing aid 2. Therefore, the user does not need to disassemble the anti-lost rope when charging the hearing aid 2 with the charging box 1, thereby simplifying the charging process of the hearing aid.

[0093] Meanwhile, since the anti-lost rope 3 can still be connected to the hearing aid 2 in the case that the hearing aid 2 is placed in the charging box 1, the user does not need to store the hearing aid and the anti-lost rope separately when carrying the hearing aid outside, thereby reducing the difficulty of storage and avoiding the loss of the anti-lost rope.
