Description

Technical Field

[0001] This utility model relates to the technical field of hearing aid charging boxes, specifically a hearing aid charging box. Background Technology

[0002] A hearing aid is a small amplifier that amplifies sounds that are otherwise inaudible. It utilizes the residual hearing of the hearing-impaired person to send the sound to the auditory center of the brain, allowing them to perceive the sound. The hearing aid charging case is a dedicated device for charging hearing aids, integrating power supply, maintenance, storage, and status management functions. It replenishes the hearing aid's power through physical contact or wireless sensing.

[0003] In real life, hearing aid charging cases need to be recharged promptly after the battery is depleted. When charging the charging case, most people simply plug the power cord directly into the charging case. This can easily cause the power cord and the plug to loosen or even fall off when the charging case is subjected to external force, resulting in the charging case failing to charge properly and affecting the subsequent use of the hearing aid. Therefore, a hearing aid charging case is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a hearing aid charging case to solve the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a hearing aid charging case, comprising:

[0006] The charging box has a fixing groove on its back, and a plug interface is fixedly provided on one side of the fixing groove.

[0007] The protective component includes two protective plates. A toggle bar is fixedly provided on the front of one of the protective plates. Springs are fixedly provided on opposite sides of both protective plates. Racks are fixedly provided on opposite sides of the inner walls of both protective plates. A transmission gear is provided on opposite sides of the two racks.

[0008] Furthermore, a lid is hinged to the top of the charging box.

[0009] Furthermore, the protective component also includes four slide bars, one end of each slide bar being fixedly disposed at the upper and lower ends of the two protective plates, and the outer walls of the four slide bars being slidably connected to the upper and lower ends of the fixing groove.

[0010] Furthermore, the opposite ends of the two springs are respectively fixedly connected to the two sides inside the charging box.

[0011] Furthermore, the protective component also includes a connecting shaft, the outer wall of which is fixedly disposed on the inner wall of the transmission gear, and the bottom end of the connecting shaft is connected to the inner bottom bearing of the charging box.

[0012] Furthermore, the outer walls of the two protective plates respectively penetrate both sides of the fixing groove.

[0014] This utility model has the following beneficial effects:

[0015] This invention features protective plates and a toggle bar. When the charging case is not charging, the two protective plates are in contact and close together. When charging the charging case, moving the toggle bar to the right causes the two protective plates to move in opposite directions and open. The protective plates then compress two springs, allowing the charging cable to be inserted into the connector. Releasing the toggle bar causes the springs to move the two protective plates towards each other until they are tightly fitted against both sides of the charging cable. This method clamps and secures the charging cable, preventing it from loosening and falling off when the charging case is subjected to external force, thus ensuring normal charging of the charging case and not affecting subsequent hearing aid charging. Additionally, the protective plates also protect the connector in the fixing slot when not charging. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a hearing aid charging case, comprising:

[0026] The charging box 11 has a fixing groove 111 on the back and a plug interface 112 fixed on one side of the fixing groove 111.

[0027] The charging box 11 is used for charging and extending the battery life of the hearing aid. When the charging box 11 is working, it generates an alternating magnetic field through the built-in coil. After the hearing aid is placed in the charging box 11, the receiving coil inside the hearing aid obtains electrical energy through electromagnetic induction, thereby realizing wireless charging. The charging box 11 has a built-in energy storage battery, which can be charged through an external power cord. When there is no external power, the hearing aid is charged through the energy storage battery.

[0028] The protective component includes two protective plates 21. A toggle bar 22 is fixedly provided on the front of one of the protective plates 21. A spring 23 is fixedly provided on the opposite side of both protective plates 21. A rack 24 is fixedly provided on the opposite side of the inner wall of both protective plates 21. A transmission gear 25 is provided on the opposite side of both racks 24.

[0029] The actuating bar 22 not only facilitates the movement of the two protective plates 21, but also limits the movement of the protective plates 21. When the actuating bar 22 contacts one side of the fixed groove 111, the transmission gear 25 is still meshing with the rack 24, thus ensuring that the two protective plates 21 move synchronously.

[0030] The top of the charging case 11 is hinged with a lid 12.

[0031] The protective component also includes four slide bars 27, one end of each slide bar 27 is fixedly mounted on the upper and lower ends of the two protective plates 21, and the outer walls of the four slide bars 27 are slidably connected to the upper and lower ends of the fixing groove 111.

[0032] The slider 27 is used to assist in the movement of the protective plate and can also increase the sealing between the protective plate 21 and the fixing groove 111. The upper and lower ends of the fixing groove 111 are provided with sliding grooves that are adapted to the slider 27, and the two ends of the sliding grooves extend into the interior of the charging box 11.

[0033] The opposite ends of the two springs are fixedly connected to the two sides inside the charging box 11, respectively.

[0034] The protective component also includes a connecting shaft 26, the outer wall of which is fixedly mounted on the inner wall of the transmission gear 25, and the bottom end of the connecting shaft 26 is connected to the inner bottom bearing of the charging box 11.

[0035] The connecting shaft 26 is used to connect the rotation of the transmission gear 25, thereby improving the stability of the synchronous movement of the two racks 24.

[0036] The outer walls of the two protective plates 21 respectively penetrate both sides of the fixing groove 111;

[0037] The protective plate 21 is slidably fitted with the fixing groove 111.

[0038] Working principle: When the charging box 11 is not charging, the two protective plates 21 are in contact with each other, thus protecting the fixing groove 111. When the charging box 11 is charging, the toggle bar 22 moves to the right, causing one of the protective plates 21 to move to the right. The movement of one protective plate 21 to the right causes the rack 24 to move to the right. The movement of the rack 24 to the right, through the transmission gear 25, causes the other rack 24 to move in the opposite direction. This causes the two protective plates 21 to open in opposite directions and press the two springs 23 respectively, allowing the charging cable to be plugged into the connector 112 on the charging box 11. Release the lever 22, and under the elastic action of the spring 23, move the two protective plates 21 toward each other until they are tightly attached to both sides of the charging cable. This method can clamp and fix the charging cable, thus preventing the charging cable from loosening and falling off the connector 112 when the charging box is subjected to external pulling force, thereby ensuring normal charging of the charging box and not affecting the subsequent charging and use of the hearing aid. At the same time, the protective plate 21 can also protect the connector 113 in the fixing groove 111 when not charging. Furthermore, the entire protective component is set inside the fixing groove 111 and the charging box body 11, which reduces its space occupation and improves the overall aesthetics.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The display component includes several indicator lights 13, which are embedded on the front of the charging box 11. Light guide plates 14 are fixedly provided on the front of the charging box 11 outside the indicator lights 13.

[0041] The light guide plate 14 is made of acrylic sheet.

[0042] Working principle: When the hearing aid is being charged by the charging box 11, the indicator light 13 on its front emits light to show the power level of the charging box 11. The light tube of the indicator light 13 is refracted and transmitted through the light guide plate 14, thereby increasing the brightness of the indicator light 13, making it convenient for the user to observe and charge in time.
