Description

Technical Field

[0001] The present invention relates to the technical field of hearing aids, and in particular to an opening and closing structure of a power supply compartment. Background Art

[0002] Hearing aids are mainly composed of components such as microphones, amplifiers, receivers and batteries. They can transmit sounds that hearing-impaired people cannot hear to the auditory center of the brain, allowing them to hear the sounds clearly. As the only power supply for hearing aids, batteries often need to be replaced in a timely manner in actual daily use to avoid affecting normal use due to the hearing aid being out of power. Existing behind-the-ear hearing aids generally use the up and down rotation of the hinge pin to open and close the battery compartment, that is, the battery compartment cover is opened and rotated upward to open the battery compartment to replace the battery. Due to the size of the battery, the opening angle of the battery compartment cannot be too large. This affects the removal and placement of the battery, especially for the elderly. It is difficult to operate. On the other hand, if impurities are accidentally mixed into this rotating battery compartment, it will be difficult to clean, affecting the service life of the hearing aid. Summary of the Invention

[0003] According to one aspect of the present invention, there is provided an opening and closing structure of a power supply compartment for a hearing aid, comprising

[0004] A power supply compartment, formed on the hearing aid housing;

[0005] A compartment cover is detachably mounted on the power supply compartment;

[0006] A battery is detachably mounted on the compartment cover;

[0007] The composite connection mechanism includes a spring, a slide plate, and a connecting block. The slide plate is slidably arranged on the power supply compartment. The spring is arranged on the housing and connected to one end of the slide plate. The connecting block is hinged to the other end of the slide plate. The compartment cover is provided with a connecting groove that cooperates with the connecting block.

[0008] When installing the compartment cover, after the connection slot and the connection block are limited and matched, rotate and slide the compartment cover to install it on the power supply compartment.

[0009] This invention provides a power supply compartment opening and closing mechanism that facilitates the removal and installation of the compartment cover for battery replacement. This mechanism utilizes a spring and a slidable slide for reciprocating motion, along with a rotatable connecting block. This allows for greater freedom of movement when pulling out and flipping the compartment cover when replacing hearing aid batteries, meeting users' needs for simple, stable, and easy cleaning of hearing aid batteries. The invention boasts an ingenious structural design, flexibly utilizing the characteristics of the sliding guide rail and the rotating shaft, resulting in convenient operation and high practicality.

[0010] In some embodiments, the composite connection mechanism further includes a pressure plate, which is disposed on the power supply compartment, and the slide plate is located between the pressure plate and the power supply compartment.

[0011] Thus, the pressing plate limits the position of the slide plate.

[0012] In some embodiments, a limiting column is provided on the power supply compartment, the limiting column is connected to the pressure plate, and a limiting groove is provided on the slide plate, and the limiting column cooperates with the limiting groove;

[0013] The limiting groove extends along the sliding direction of the slide plate, and the limiting column can limit the stroke of the slide plate.

[0014] Therefore, the travel of the slide plate is controlled by utilizing the cooperation between the limiting column and the limiting groove, which can prevent the slide plate from falling off.

[0015] In some embodiments, a guide bar protruding toward the slide plate is provided on the pressing plate, and the guide bar extends along the sliding direction of the slide plate;

[0016] There are convex strips on both sides of the slide plate, which extend along the sliding direction of the slide plate, and a guide groove is formed between the two convex strips;

[0017] The guide strip cooperates with the guide groove.

[0018] Therefore, the pressure plate also has a guiding effect on the slide plate, and the motion trajectory of the slide plate is guided by the cooperation relationship between the guide bar and the guide groove, which can ensure and support the slide plate to move back and forth in a straight line.

[0019] In some embodiments, one end of the slide away from the spring is bent into a circular ring shape and has a hinge portion in the middle, and the connecting block is mounted on the hinge portion via a rotating shaft.

[0020] Thus, the curved ring and the hinge portion provide installation space for the hinge of the connecting block, and can accommodate the rotating shaft and the connecting shaft.

[0021] In some embodiments, a limiting strip is provided on the connecting block, and the limiting strip and the sliding plate can be separated and abutted against each other;

[0022] By rotating the connecting block, the limiting bar is separated from or counteracted with the sliding plate.

[0023] Therefore, through the cooperation between the limiting bar and the slide plate, the swing angle of the connecting block can be limited, thereby preventing the connecting block from swinging into the power supply compartment.

[0024] In some embodiments, one end of the slide plate close to the spring is bent at a right angle and has recessed portions on both sides, and the recessed portions of the spring are engaged.

[0025] Thus, the recessed portion is engaged with the spring, thereby preventing the engaging portion of the spring from falling off.

[0026] In some embodiments, a mounting slot is provided on the compartment cover, and the battery is detachably disposed in the mounting slot.

[0027] Thus, the mounting groove is used to mount the battery, and the battery can be mounted by inserting the compartment cover.

[0028] In some embodiments, the mounting slot is hollowed out, and the side wall of the power supply compartment is provided with two springs;

[0029] When the compartment cover is installed, the battery is clamped between two spring pieces, one of which directly contacts the battery, and the other penetrates the installation slot and contacts the battery.

[0030] Thus, by installing the compartment cover, the battery is clamped between the two springs, which are not only used to maintain the balance of the battery, but also serve as conductors for the battery to supply power.

[0031] In some embodiments, the opening and closing structure of the power supply compartment also includes a mortise and tenon connection mechanism, including a female buckle and a male buckle. The female buckle is molded at the power supply compartment position on the shell, and the female buckle is located on the side of the power supply compartment away from the composite connection mechanism. The male buckle is molded on the compartment cover, and the male buckle is located on the side of the compartment cover away from the connection groove. The female buckle and the male buckle are interlocked.

[0032] Therefore, a mortise and tenon joint mechanism is also provided on the side away from the composite connection mechanism, effectively improving the stability of the opening and closing structure. One end of the compartment cover is connected to the connecting shaft and simultaneously engages with the lower part of the housing, while the other end is connected to the upper part of the housing, forming a complete hearing aid structure and ensuring the opening and closing of the power supply compartment.

[0033] The beneficial effects of this invention are embodied in its breakthrough in conventional battery replacement control mechanisms. By extending and rotating the hearing aid's power supply compartment to open and close, the compartment provides a larger contact area, making battery replacement easier for users. This is particularly beneficial for the elderly, who often have reduced fine control of their hands. This increased contact area effectively reduces the difficulty of battery replacement for those with reduced hand control. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] More specifically, the opening and closing structure includes a composite connection mechanism 600 and a mortise and tenon connection mechanism 700. The composite connection mechanism 600 and the mortise and tenon connection mechanism 700 are respectively arranged above and below the power supply compartment 101.

[0047] Combine Figure 3-6 The composite connection mechanism 600 includes a spring 610, a slide 620, a connecting block 630, and a pressure plate 640. The slide 620 is slidably mounted on the power supply compartment 101; the pressure plate 640 is mounted on the power supply compartment 101, and the slide 620 is located between the pressure plate 640 and the power supply compartment 101, with the pressure plate 640 used to limit the position of the slide 620; one end of the spring 610 is fixed to the housing 100, and the other end of the spring 610 is connected to one end of the slide 620; the connecting block 630 is hinged to the other end of the slide 620, and the compartment cover 500 is provided with a connecting groove 501 that cooperates with the connecting block 630. When installing the compartment cover 500, after the connecting groove 501 and the connecting block 630 are limited and matched, the compartment cover 500 is rotated and slid to be installed on the power supply compartment 101. This structure provides a spring 610 and a slidable slide 620 for reciprocating motion, and is also provided with a rotatable and swingable connecting block 630, so that the compartment cover 500 can be pulled out and flipped more significantly when replacing the hearing aid battery 300, meeting the user's needs for simple, stable and easy cleaning of the hearing aid battery 300.

[0048] Combine Figure 6The pressure plate 640 is provided with a guide bar 641 that protrudes toward the slide plate 620 and extends in the sliding direction of the slide plate 620. The slide plate 620 is provided with ridges 621 on both sides of the slide plate 620, extending in the sliding direction of the slide plate 620. A guide groove 622 is formed between the ridges 621. The guide bar 641 cooperates with the guide groove 622. The pressure plate 640 also guides the slide plate 620. The cooperation between the guide bar 641 and the guide groove 622 guides the movement trajectory of the slide plate 620, ensuring and supporting the slide plate 620's reciprocating motion in a straight line.

[0049] Combine Figure 3-6 The power supply compartment 101 is provided with a limiting post 650, which is connected to the pressure plate 640.

[0053] Combine Figure 7 Located at the lower portion of the compartment cover 500, i.e., at the front and rear sides of the connection slot 501, two latches 800 are further provided. The two latches 800 are configured to protrude from the surface in the depth direction of the connection slot 501. When the compartment cover 500 is installed, the latches 800 are embedded in the power supply compartment 101 and engage with the embedded latch of the power supply compartment 101.

[0054] Combine Figure 5 and 7 The compartment cover 500 is provided with a mounting groove 502, and the battery 300 is detachably arranged in the mounting groove 502. The mounting groove 502 is used to install the battery 300, and the battery 300 can be installed by inserting the compartment cover 500.

[0055] Combine Figure 5 and 7 The mounting slot 502 is hollowed out, and two spring clips 400 are provided on the sidewalls of the power supply compartment 101. When the compartment cover 500 is installed, the battery 300 is clamped between the two spring clips 400, one of which directly contacts the battery 300, while the other penetrates the mounting slot 502 and contacts the battery 300. With the compartment cover 500 installed, the battery 300 is clamped between the two spring clips 400, which not only maintain the balance of the battery 300 but also serve as conductors for the battery 300 to provide power.

[0056] When installing the compartment cover 500:

[0057] First, make the connection groove 501 of the compartment cover 500 fit with the connection block 630; then, rotate the compartment cover 500 so that the male buckle 720 of the compartment cover 500 is aligned with the female buckle 710 of the power supply compartment 101; finally, slide the compartment cover 500 so that the male buckle 720 and the female buckle 710 fit together, and the compartment cover 500 can be installed on the power supply compartment 101.

[0058] When disassembling the compartment cover 500: simply slide the compartment cover 500 to disengage the male buckle 720 and the female buckle 710, and then disengage the connecting groove 501 of the compartment cover 500 from the connecting block 630.

[0059] This design breaks through the traditional battery 300 replacement control mechanism in the industry. By stretching and rotating the hearing aid power supply compartment 101 to open and close, the compartment 101 has a larger contact area, making it easier for users to replace the battery 300. This is especially true for the elderly, who tend to have reduced fine control of their hands. The larger contact area provided by this invention effectively reduces the difficulty of replacing the battery 300 for those with reduced hand control.

[0060] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
