Description

Technical Field

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

[0005] The present invention adopts the following technical solution: A battery snap-on connection structure for an ear-hook walkie-talkie includes a base and a snap-on connector; The base is provided with a groove, and the end face of the groove is provided with a first electrode. The first electrode is electrically connected to the internal circuit of the walkie-talkie body or battery fixed to the base. Multiple L-shaped slots are evenly distributed around the inner wall of the groove. Each slot includes a vertical section and a parallel section. The vertical section passes through the end face of the groove opening. The parallel section is parallel to the end face of the groove, and the side of the parallel section away from the vertical section is provided with a protruding limiting part. The end face of the rotary connector is provided with a second electrode, which is electrically connected to the internal circuit of the walkie-talkie body or battery fixed by the rotary connector; the rotary connector has a plurality of limiting posts evenly distributed around its circumference. The base is fixedly installed on either the walkie-talkie body or the battery, and the rotary connector is fixedly installed on the other of the walkie-talkie body or the battery. During installation, each of the limiting posts of the rotary joint is inserted into the vertical section of each of the slots of the base to the junction of the vertical section and the parallel section. Then, the rotary joint is rotated so that the limiting posts are pressed through the limiting part and locked at the end of the parallel section. At the same time, the first electrode and the second electrode are pressed into contact and connected.

[0006] In one possible implementation, the connection structure further includes an ear hook arm, one end of which is connected to the walkie-talkie body, and the base or the screw connector is disposed at the other end of the ear hook arm, so that the walkie-talkie body is connected to the battery through the ear hook arm, and the battery is located behind the auricle when the ear hook arm is hung on the ear.

[0007] In one possible implementation, after the base and the rotary joint are connected, magnets are provided on their corresponding end faces. When the rotary joint is fitted into the base, the magnets of the base and the magnets of the rotary joint attract each other.

[0008] 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: This utility model realizes the locking connection between the battery and the walkie-talkie body through the connection between the base and the rotary connector. Specifically, the precise assembly process is achieved through the cooperation between the limiting post of the rotary connector and the slot in the base. When rotated into place, the electrodes of the walkie-talkie body and the electrodes of the battery are automatically contacted and locked, which effectively improves the convenience of battery installation and removal. Only simple rotation and insertion / removal actions are needed to simultaneously complete the battery fixing and circuit conduction, which can improve the continuous use capability of the walkie-talkie and is particularly suitable for work scenarios that require long-term communication.

[0014] 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.

[0015] In this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown 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 orientation of the components in the accompanying drawings.

[0016] The utility model provides a battery screw-on connection structure for an ear-hook walkie-talkie, as shown in the attached figure. Figure 1 As shown, the connection structure includes a base 4 and a screw connector 5. The base 4 is fixedly installed on either the walkie-talkie body 1 or the battery 2, and the screw connector 5 is fixedly installed on the other of the walkie-talkie body 1 or the battery 2. The fixing method can be an integral molding method, which is used to realize the detachable locking of the battery 2 relative to the walkie-talkie body 1 so as to realize power transmission.

[0017] As attached Figure 2 and 3 As shown, the base 4 has a groove 41, and the end face of the groove 41 is provided with a first electrode. The first electrode is electrically connected to the internal circuit of the walkie-talkie body 1 or the battery 2 fixed to the base 4. Taking the base 4 being fixed to the walkie-talkie body 1 as an example, the first electrode is electrically connected to the circuit of each functional module inside the walkie-talkie body 1. The inner wall of the groove 41 also has a plurality of L-shaped slots 42 evenly distributed circumferentially. The slots 42 include a vertical section 421 and a parallel section 422 that are connected. The vertical section 421 penetrates the end face of the opening of the groove 41, and the parallel section 422 is parallel to the end face of the base 4 outside the slot of the groove 41. The side of the parallel section 422 away from the vertical section 421 is provided with a protruding limiting part 43.

[0018] As attached Figure 4 As shown, the end face of the rotary connector 5 is provided with a second electrode 6, which is electrically connected to the internal circuit of the walkie-talkie body 1 or the battery 2 to which the rotary connector 5 is fixed. Taking the base 4 fixed to the walkie-talkie body 1 in the above embodiment as an example, the rotary connector 5 should be fixedly installed in the other of the walkie-talkie body 1 or the battery 2. Therefore, the rotary connector 5 needs to be fixed to the battery 2, and the second electrode is electrically connected to the internal circuit of the battery 2. The rotary connector 5 also has a plurality of limiting posts 51 evenly distributed around its circumference, each limiting post 51 corresponding to each slot 42.

[0019] When battery 2 needs to be installed, see attached Figure 5As shown, each limiting post 51 of the rotary connector 5 is inserted one by one into the vertical section 421 of each slot 42 of the base 4, until the limiting post 51 abuts against the junction of the vertical section 421 and the parallel section 422; then the rotary connector 5 is rotated so that the limiting post 51 passes through the limiting part 43. At this time, the limiting post 51 is blocked by the limiting part 43 and is fastened to the end of the parallel section 422, and the first electrode and the second electrode 6 are pressed into contact and connected. Specifically, both the base 4 and the screw connector 5 can be made of plastic, giving the portion of the base 4 from the parallel section 422 to the groove end face of the groove 41 elasticity. The limiting post 51 and the limiting part 43 can undergo moderate elastic deformation during rotation. The limiting post 51 smoothly passes over the limiting part 43 and the portion from the parallel section 42 to the groove end face of the groove 41 through elastic compression, forming a tight fit with the end face of the parallel section 422 and the limiting part 43. This ensures that, without external force intervention, the limiting part 43 blocks the limiting post 51, effectively preventing the screw connector 5 from accidentally loosening. This allows the screw connector 5 to maintain a stable connection with the base 4 without external force, ensuring the reliability of the battery 2 locking. This installation method only requires the insertion and rotation steps, making it very convenient.

[0020] When it is necessary to remove the battery 2, hold the walkie-talkie body 1 or the battery 2 connected to the rotary connector 5 and apply rotational torque to make the limiting post 51 move backward past the limiting part 43 and return to the vertical section 421 area. Then, pull the limiting post 51 out of the slot 42 along the vertical section 421 to complete the removal of the battery 2. This removal method only requires the operation of rotating and pulling out, so it is very convenient.

[0021] Referring to the attached diagram, magnets 7 (such as neodymium iron boron magnets) are provided on the corresponding end faces of the base 4 and the screw connector 5 after connection. When the screw connector 5 is fitted into the base 4, the magnets 7 of the base 4 and the screw connector 5 attract each other, thereby improving the firmness of the connection between the base 4 and the screw connector 5 and further preventing the screw connector 5 from accidentally coming loose from the base 4.

[0022] 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 4 or screw connector 5 is disposed at the other end of the ear hook arm 3, so that the walkie-talkie body 1 is connected to the battery 2 through 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, so that the walkie-talkie body 1 is naturally positioned on the front side of the auricle, while the battery 2 is balanced and distributed on the back side of the auricle, forming a symmetrical weight distribution system. This innovative spatial layout effectively reduces the feeling of unilateral load, significantly improves wearing comfort through the principle of mechanical balance, and ensures the stability of the device during mobile use.

[0023] In summary, the structure of this utility model achieves a locking connection and power transmission between the battery 2 and the walkie-talkie body through the connection between the base 4 and the rotary connector 5. The engagement of the limiting post 51 of the rotary connector 5 and the slot 42 within the base 4 ensures precise assembly, automatically completing the contact and locking of the electrodes of the walkie-talkie body 1 and the battery 2 upon rotation into position. To remove the battery 2, rotate the rotary connector 5 to reverse the limiting post 51 past the limiting part 43 and return it to the vertical section 421 area, then pull the limiting post 51 out of the slot 42. It is evident that the connection structure of this utility model effectively improves the ease of battery 2 installation and removal, requiring only simple rotation and insertion / removal actions to simultaneously fix the battery 2 and establish circuitry, enhancing the walkie-talkie's continuous operation capability, making it particularly suitable for work scenarios requiring long-term communication.

[0024] 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.
