Description

Technical Field

[0001] This utility model relates to the field of consumer electronics technology, and in particular to an earphone with a snap-on detachment structure. Background Technology

[0002] With the development of wireless technology, Bluetooth headsets have become an indispensable electronic product in people's daily lives. In pursuit of portability and aesthetics, most existing Bluetooth headsets adopt an integrated design, with the battery built into the headset shell and charged via Micro-USB or Type-C interface.

[0003] However, this design has some inherent flaws: Battery life limitation: The built-in battery has a limited number of charge and discharge cycles. When the battery performance degrades, users usually cannot replace it themselves, causing the entire headset to become unusable and resulting in a waste of resources.

[0004] Battery life anxiety: When out for a long time or traveling, once the earphone battery runs out, users have to find a power source and charging cable to charge it, and cannot immediately resume use, affecting the continuity of use.

[0005] Charging port wear and tear: The charging port needs to be plugged and unplugged frequently, which can easily cause physical wear or damage. Once the charging port fails, the headphones will not work.

[0006] Although there are some earphone designs with replaceable batteries on the market, their structures are usually quite complex, the replacement process is cumbersome, or the connection structure is not stable enough, making them prone to falling off during exercise or other scenarios.

[0007] Therefore, how to design a headset with a simple structure, a stable connection, convenient operation, and quick battery replacement is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0008] (a) Technical problems that need to be solved This utility model aims to overcome the shortcomings of the prior art and provide an earphone with a snap-on disassembly structure. Its purpose is to realize the quick disassembly and installation of the battery module. This structure is not only stable and reliable, but also simple and intuitive to operate, while ensuring the electrical connection stability of the device during rotation and use.

[0009] (II) Technical Solution To achieve the above objectives, the present invention adopts the following technical solution: An earphone with a snap-on detachment structure, comprising: Earphone body (10); A connector (20) is fixedly disposed at one end of the earphone body (10), and at least one latching protrusion (21) is provided on its outer side; A cover (30) has an internal slot (31) for placing a battery. The cover (30) is detachably connected to the connecting seat (20). A sliding groove (32) is annularly arranged inside the cover (30), and a groove is provided at the connection contact end face between the cover (30) and the connecting seat (20). At least one first slot (33) is provided for guiding the card protrusion (21) into the sliding groove (32); At least one second slot (34) is provided for guiding the card protrusion (21) out of the sliding groove (32).

[0010] As a preferred embodiment, a first inclined portion (331) is provided in the first slot (33), and the first inclined portion (331) is inclined from the connection contact end of the cover (30) and the connecting seat (20) towards the inside of the cover (30).

[0011] As a preferred embodiment, a second inclined portion (341) is provided in the second slot (34), and the second inclined portion (341) is inclined from the inside of the cover (30) toward the connection contact end face between the cover (30) and the connecting seat (20).

[0012] As a further preferred embodiment, the bottom surface of the second inclined portion (341) near the sliding groove (32) covers the movement path of the latching protrusion (21), so that when the latching protrusion (21) enters the second slot (34) from the sliding groove (32), it needs to pass over the bottom surface of the second inclined portion (341) under the action of external force. This design forms a limiting structure to prevent accidental dislodgement.

[0013] As a further preferred embodiment, the bottom surface of the second inclined portion (341) covers the latch protrusion (21) by a height of 2 to 3 millimeters. This height provides sufficient resistance to prevent accidental detachment while ensuring that the user can disassemble it with moderate force.

[0014] As a preferred embodiment, the cam (21) is made of an elastic material, which allows it to undergo slight deformation as it passes over the second inclined portion (341), thereby protecting the structure from damage and providing a smooth "click" feel.

[0015] To achieve electrical connection, this utility model also includes a conductive structure (40), which includes an annular conductive base (41), a positive contact (42), a negative contact (43), and an insulating base (44). The positive contact (42) and the negative contact (43) are disposed within the connector (20) and connected to the internal circuit of the earphone body (10). The annular conductive base (41) is fixedly disposed within the connector (20) and electrically connected to the negative contact (43). The center of the annular conductive base (41) is hollow to expose the positive contact (42). The insulating base (44) is disposed within the connector (20) to isolate the positive and negative electrodes, and its center has a through hole adapted to the positive contact (42).

[0016] As a preferred embodiment, the insulating base (44) is provided with a groove (441) on the bottom periphery, and the annular conductive base (41) is stably coaxially installed by being inserted into the groove (441).

[0017] As a further preferred embodiment, the conductive structure further includes a conductive sheet (45). The insulating base (44) is recessed outward to form a first bayonet (442), and the annular conductive base (41) is provided with a second slot (411) that mates with it. When the annular conductive base (41) is engaged in the slot (441), the outside of the first bayonet (442) is engaged in the second slot (411). One end of the conductive sheet (45) is engaged in the first bayonet (442), and the other end is connected to the negative contact (43) to form a reliable conductive path.

[0018] (III) Beneficial Effects Compared with the prior art, the present invention has the following beneficial effects: Easy to operate and flexible connection: During installation, users only need to align the latch (21) of the cover (30) with the first slot (33) and press it to easily complete the insertion. After insertion, the cover (30) can rotate freely 360 degrees on the connector (20) without worrying about tightening or loosening it, or aligning it at a specific angle, which greatly improves the user experience.

[0019] The structure is robust and prevents accidental detachment: By setting a second inclined part (341) with a limiting function in the second slot (34), the latch (21) will not accidentally slide out when rotating in the sliding groove (32). Disassembly requires a clear action of "rotating and aligning and pulling out" and overcoming a certain resistance, which effectively avoids the cover (battery compartment) from accidentally falling off due to collision or vibration in scenarios such as movement and walking.

[0020] Durable and extends product lifespan: The snap-fit ​​structure and ring-shaped conductive structure of this invention replace the traditional USB charging interface, avoiding physical wear and damage caused by frequent plugging and unplugging. At the same time, the replaceable battery design allows users to simply replace the battery inside the cover (30) when the battery ages, extending the overall lifespan of the headphones and conforming to the concept of green environmental protection.

[0021] Reliable electrical connection: The design of the annular conductive base (41) ensures that no matter how the cover (30) rotates, the negative terminal of the battery inside always maintains stable contact with the annular conductive base (41), and the positive terminal contact (42) in the center is always aligned with the positive terminal of the battery, ensuring continuous and reliable power supply.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0031] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will be able to understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] Please see Figures 1 to 7 This utility model provides an earphone with a snap-on detachable structure. The earphone mainly includes an earphone body (10), a connector (20) fixed to one end of the earphone body (10), and a cover (30) detachably mounted on the connector (20).

[0036] The connecting seat (20) is the main part of the connection, and two symmetrical locking protrusions (21) are fixedly provided on its outer peripheral side (two are taken as an example, one or more can be implemented in this utility model). In this embodiment, the locking protrusions (21) are preferably made of engineering plastic or metal elastomer with a certain elasticity, which provides the possibility for them to pass over the limiting structure in the future.

[0037] The cover (30) is a component that houses the battery (not shown), and it has a slot (31) inside for placing the battery. The core structure of the cover (30) is inside. A sliding groove (32) is formed in a ring on its inner wall. On the open end face of the cover (30), that is, the end face that contacts the connecting seat (20), two first slots (33) and two second slots (34) are formed, corresponding to the latching protrusion (21).

[0038] The installation process is as follows: The user holds the cover (30), aligns the first slot (33) with the latch (21) on the connector (20), and then presses it towards the connector (20). Inside the first slot (33), there is a first inclined part (331), which is a gentle slope structure. When the latch (21) contacts the first inclined part (331), the pressing force is decomposed along the slope, generating a force that pushes the latch (21) into the sliding groove (32), thereby guiding the latch (21) to slide smoothly into the sliding groove (32). Once the latch (21) is fully in the sliding groove (32), the user can release it. At this time, the cover (30) and the connector (20) are mechanically locked, and the cover (30) can rotate freely around the connector (20).

[0039] The disassembly process is as follows: The user needs to rotate the cover (30) until the protrusion (21) moves to the entrance of the second slot (34) through the guide of the sliding groove (32). The second slot (34) also has a second inclined part (341). Unlike the first inclined part (331), the end of the second inclined part (341) near the sliding groove (32) forms a "protrusion" or "threshold", the bottom surface of which partially covers the movement path of the protrusion (21). Specifically, the height of this protrusion is preferably 2 mm to 3 mm. Therefore, when the protrusion (21) wants to enter the second slot (34) from the sliding groove (32), it will be blocked by this protrusion. The user needs to apply an axial pull-out force, using the elasticity of the protrusion (21) itself or the small elastic deformation of the connecting structure, to make the protrusion (21) "jump" over the protrusion and slide smoothly out along the inclined surface of the second inclined part (341), thereby completing the disassembly of the cover (30). This design cleverly achieves the effect of being "easy to install and difficult to accidentally fall off".

[0040] Please see Figure 6To power the headphones, a precision conductive structure (40) is installed inside the connector (20). The core of this structure is the coaxially arranged positive and negative electrodes. The positive contact (42) is usually a probe or a contact point, located at the center of the connector (20). An insulating base (44) is provided around the positive contact (42), which completely isolates the positive electrode from the external negative electrode structure. A through hole is opened in the center of the insulating base (44), allowing the positive contact (42) to pass through and be exposed to contact the positive electrode of the battery.

[0041] The annular conductive base (41) is the main contact of the negative electrode. It is a metal ring that fits over the outside of the insulating base (44). This annular design is one of the key features of this invention, ensuring that the negative electrode of the battery maintains an uninterrupted electrical connection no matter what angle the cover (30) is rotated to.

[0042] To ensure a more secure and reliable assembly of the conductive structure, a groove (441) is formed around the bottom periphery of the insulating base (44), into which the annular conductive base (41) can be directly inserted for precise positioning. Furthermore, to ensure a stable connection between the annular conductive base (41) and the negative contact (43) of the internal circuit of the earphone body (10), a first recessed slot (442) is designed on the insulating base (44), and a second slot (411) is formed at the corresponding position on the annular conductive base (41). One end of a conductive sheet (45) can be firmly inserted into the space formed by the first slot (442) and the second slot (411). The first slot (442) has a gap, so that the second slot (411) is embedded in the first slot (442). At the same time, the surface of the second slot (411) is exposed to the first slot (442). One end of the conductive sheet (45) is in contact with the negative contact (43) through the exposed surface of the second slot (411), thus forming a stable, low-resistance conductive path.

[0043] In summary, this utility model, through its ingenious buckle, inclined surface, limiting structure, and ring conductive design, successfully realizes an earphone that is simple in structure, easy to use, reliable in connection, and supports quick battery replacement.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
