Description

Technical Field

[0001] This utility model relates to the field of ear-hook walkie-talkie structures, and in particular to a battery push-button connection structure for an ear-hook walkie-talkie. Background Technology

[0002] In the field of ear-hook walkie-talkies, the battery installation structure generally adopts a built-in, non-removable design, with the battery permanently connected to the walkie-talkie body through an insert injection molding process. While this design simplifies the product structure, once the battery is depleted, it must be discontinued for charging, and the device's operating time cannot be extended by replacing the battery.

[0003] In other words, the main technical problem with current ear-hook walkie-talkies is that the built-in non-removable battery severely limits the device's continuous operating time. When the battery runs out, users have to interrupt communication and wait for it to recharge, which can cause serious work interruptions in professional applications requiring long-term continuous operation. Especially in critical mission scenarios such as the catering industry and industrial inspection, this design flaw can lead to important communication interruptions, affecting the efficiency of work communication. Utility Model Content

[0004] To address the shortcomings mentioned above in the background technology, this utility model provides a battery push-type connection structure for an ear-hook walkie-talkie.

[0005] The present invention adopts the following technical solution: A battery push-type connection structure for an ear-hook walkie-talkie, characterized in that the connection structure includes a base and a connector, wherein the base and the connector are optionally disposed on the walkie-talkie body and the other is disposed on the battery; The base is provided with a connector, the sidewall of the connector is circumferentially distributed with multiple protrusions, and the bottom surface inside the connector is provided with a first electrode. The outer diameter of the connector is clearance-fitted with the inner diameter of the socket, and the outer ring surface of the connector is also provided with an annular groove. The end face of the connector is provided with a second electrode. When the connector is inserted into the socket, the annular groove and the protrusion form a snap-fit ​​fixation, and at the same time, the first electrode and the second electrode make contact and conduction.

[0006] In one possible implementation, the connector ring surface is provided with two limiting rings, and the gap between the two limiting rings forms the annular groove. When the connector is inserted into the socket, the limiting rings cross the protrusion to form a snap-fit ​​fixation.

[0007] In one possible implementation, magnets are provided on the corresponding end faces of the base and the connector after they are connected. When the annular groove and the protrusion are fixed in a snap-fit ​​manner, the magnets of the battery and the magnets of the walkie-talkie body attract each other.

[0008] In one possible implementation, one end of the ear hook is connected to the walkie-talkie body, and the base or the connector is disposed at the other end of the ear hook, so that the walkie-talkie body is connected to the battery through the ear hook, and the battery is located behind the ear when the ear hook is hung on the ear.

[0009] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: The protrusions of the connector and the base of this utility model interlock with the snap-fit ​​of the annular groove, realizing the detachable connection between the battery and the walkie-talkie body, and the battery maintains a stable connection state relative to the walkie-talkie body after connection. Compared with walkie-talkies with built-in non-removable batteries that require charging, this connection structure configuration enables rapid battery replacement, significantly reduces the time of communication interruption, avoids the risk of long-term communication interruption due to charging, and allows users to maintain continuous online operation by rotating spare batteries, which is beneficial to improving communication efficiency.

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0016] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0017] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0018] The utility model provides a battery push-type connection structure for an ear-hook walkie-talkie, as shown in the attached figure. Figure 1 and 2 As shown, the connection structure includes a base 5 and a connector 4. The base 5 and the connector 4 are optionally disposed on the walkie-talkie body 1 and the other is disposed on the battery 2. The two are disposed in one piece, which is used to realize the detachable connection of the battery 2 to the walkie-talkie body 1 and realize power transmission.

[0019] Continue to refer to the appendix Figure 1 The base 5 has a connector 51 inside, and multiple protrusions 52 are distributed circumferentially on the side wall of the connector 51. A first electrode 61 is also provided on the bottom surface inside the connector 51. This first electrode 61 is electrically connected to the internal circuitry of the walkie-talkie body 1 or the battery 2 fixed to the base 5. Taking the base 5 fixed to the walkie-talkie body 1 as an example, the first electrode 61 is electrically connected to the circuitry of each functional module inside the walkie-talkie body 1.

[0020] As attached Figure 4 and 5 As shown, the outer diameter of the connector 4 is clearance-fitted with the inner diameter of the socket 51, ensuring that the connector 4 can be smoothly inserted into the socket 51 axially. The outer ring surface of the connector 4 is also provided with an annular groove 41, and the end face of the connector 4 is provided with a second electrode 62. When the connector 4 is fully inserted into the socket 51, the group of protrusions 52 on the inner wall of the socket 51 and the annular groove 41 on the outer ring surface of the connector 4 create a radial interlocking effect, causing the protrusions 52 to embed into the annular groove 41 and form an interlock. This interlocking mechanism reliably restrains the connector 4 within the socket 51 base 5 when there is no external axial tensile force, effectively preventing the connector 4 from accidentally coming out. Simultaneously, the first electrode 61 at the bottom of the socket 51 establishes a surface contact conductive connection with the second electrode 62 on the end face of the connector 4, achieving a stable connection between the connector 4 and the base 5 while ensuring continuous and stable contact of the electrodes, thereby maintaining the connection state between the battery 2 and the walkie-talkie body and the physical stability of the power transmission path.

[0021] Furthermore, two retaining rings are provided on the annular surface of the connector 4. The connector 4 and the retaining rings are integrally formed by injection molding. The base 5 and the protrusions 52 distributed on its inner wall are also integrally injection molded into a rigid whole. The gap between the two retaining rings forms an annular groove 41. When the connector 4 is axially inserted into the connector 51, the protrusions 52 and the retaining rings are squeezed relative to each other. This causes the rigid plastic base 5 wall to undergo instantaneous diameter expansion deformation under the extrusion force, which drives the protrusions 52 to move outward relative to the retaining rings. This allows the retaining rings to overcome the protrusions 52. After the retaining rings have completely crossed the protrusions 52, the base 5 returns to its original deformation, and the protrusions 52 immediately spring back and embed into the internal space of the annular groove 41. At this time, the retaining rings and the protrusions 52 form a circumferentially constrained snap-fit ​​relationship, ensuring a stable connection between the battery 2 and the walkie-talkie body. This structure achieves a one-way self-locking function for the axial movement of the connector through the synergistic effect of material elastic deformation and rigid reset, effectively eliminating the risk of axial movement of the connection structure after assembly.

[0022] When battery 2 needs to be removed, an axial pulling force is applied along the direction in which battery 2 detaches from the walkie-talkie body. This force is transmitted to the base 5, causing the wall of the base 5 to undergo radial elastic expansion deformation under compression. The protrusion 52 on the inner wall of the base 5 then displaces and disengages from the constraint space of the annular groove 41. At this point, the interlocking state between the limiting ring and the protrusion 52 is released, and battery 2 smoothly exits, completing the disassembly. This disassembly mechanism relies solely on the linear motion path of the insertion and removal action to achieve a complete connection and separation cycle between battery 2 and the main unit, without the need for rotational alignment or auxiliary tools, significantly simplifying the replacement process. Compared to walkie-talkies with built-in non-removable batteries that require charging, this solution achieves rapid physical replacement of battery 2 through a snap-fit ​​connection structure with interlocking protrusion 52 and annular groove 41. This significantly reduces the time the device is interrupted from communication, avoids the risk of prolonged communication interruption due to charging, and allows users to maintain continuous online operation by rotating spare batteries 2, thus improving communication efficiency.

[0023] It is worth mentioning that the interlocking connection structure of the protrusion 52 and the annular groove 41 provides a physical basis for the hot-swappable replacement strategy of the backup battery 2 of the ear-hook walkie-talkie.

[0024] Please refer to the appendix. Figure 3 After connection, the base 5 and connector 4 are equipped with magnets 7 (such as neodymium iron boron magnets) on their corresponding end faces. When the annular groove 41 and the protrusion 52 form a snap-fit ​​fixation, the magnet 7 of the battery 2 and the magnet 7 of the walkie-talkie body 1 come into contact and attract each other. This further enhances the firmness of the connection between the base 5 and connector 4, and further prevents the connector 4 from accidentally coming loose from the base 5.

[0025] Furthermore, the structure of this utility model also includes an ear hook arm 3, one end of which is connected to the walkie-talkie body 1, and the base 5 or connector 4 is disposed at the other end of the ear hook arm 3, allowing the walkie-talkie body 1 to be connected to the battery 2 via the ear hook arm 3. When the device is worn, the ear hook arm 3 conforms to the contour of the ear with an ergonomic curve, allowing the walkie-talkie body 1 to be naturally positioned on the front side of the auricle, while the battery 2 provides balanced weight distribution on the back side of the auricle, forming a symmetrical weight distribution system. This innovative spatial layout effectively reduces the feeling of unilateral weight, significantly improves wearing comfort through the principle of mechanical balance, and ensures the stability of the device during mobile use.

[0026] In summary, the battery 2 connection structure of this utility model achieves axial blind insertion through the gap fit between the connector 51 of the base 5 and the connector 4. The interlocking mechanism formed by the protrusion 52 embedded in the annular groove 41 enables the detachable connection between the battery 2 and the walkie-talkie body, and the battery 2 maintains a stable connection relative to the walkie-talkie body after connection. During the insertion and removal of the battery 2, tool-free switching between self-locking and unlocking states can be achieved, simplifying the battery 2 replacement action to a single axial linear movement and significantly shortening the disassembly cycle to the second level. Compared to the fixed charging solution for the walkie-talkie battery 2, this snap-fit ​​connection structure significantly reduces the communication interruption time caused by device charging, improving the continuous online rate and task response time of the team's communication network in scenarios such as field inspections and emergency command, while ensuring the durable and stable conductivity of the electrode contact interface.

[0027] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
