Description

Technical Field

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

[0005] The present invention adopts the following technical solution: A flexible battery connection structure for an ear-hook walkie-talkie includes a connector sleeve and a connector plug, wherein one of the connector sleeve and the connector plug is disposed on the walkie-talkie body and the other is disposed on the battery; The connector sleeve has an internal receiving groove, and the side wall of the connector sleeve is provided with a limiting hole that penetrates the inside and outside of the receiving groove. A first electrode is provided on the bottom surface inside the receiving groove. The outer diameter of the connector is clearance-fitted with the inner diameter of the receiving groove. A second electrode is provided on the end face of the connector, and a limiting pin is provided on the side of the connector. The limiting pin and the connector are connected by an elastic element. The elastic force of the elastic element causes the limiting pin to move elastically relative to the center of the connector. When the connector is inserted into the receiving groove, and the elastic element pushes the limiting pin into the limiting hole, the first electrode and the second electrode make contact and conduct.

[0006] In one possible implementation, the elastic element is a spring sheet, one end of which is fixed to the connector and is parallel to the axis of the connector. The limiting pin is fixed to the other end of the spring sheet facing outward from the connector. When the connector is inserted into the receiving groove, the spring sheet swings and deforms towards the connector. The elastic force of the spring sheet returning to its original position drives the limiting pin to push radially outward into the limiting hole.

[0007] In one possible implementation, the elastic element is a spring, with the connector and the limiting pin connected to its two ends respectively. When the connector is inserted into the receiving groove, the spring is compressed and its restoring elastic force drives the limiting pin to be pushed radially outward into the limiting hole.

[0008] In one possible implementation, magnets are provided on the corresponding end faces of the connector sleeve and the connector after they are connected. After the elastic member pushes the limiting pin into the limiting hole, the magnets of the battery and the walkie-talkie body attract each other.

[0009] 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 connector sleeve or connector plug 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 ear when the ear hook arm is hung on the ear.

[0010] 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: When installing the battery, through the synergistic action of the limiting pin and the elastic element, automatic alignment and self-locking are achieved when the connector is inserted into the connector sleeve, ensuring that the first electrode and the second electrode make immediate and reliable contact and conduction, and guaranteeing the long-term stability of the circuit connection. When removing the battery, the limiting pin is pushed inward at the limiting hole to disengage the limiting pin from the limiting hole and release the locking state. Then, the connector can be pulled out from the receiving groove to complete the battery removal. It can be seen that the connection structure of this utility model can simultaneously complete the battery fixing and circuit conduction with only a simple pressing and plugging action, which can improve the continuous use capability of the walkie-talkie and is particularly suitable for work scenarios that require long-term communication.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] The utility model provides a flexible connection structure for the battery 2 of an ear-hook walkie-talkie, as shown in the attached figure. Figure 1 As shown, the connection structure includes a connector sleeve 4 and a connector plug 5. The connector sleeve 4 and the connector plug 5 are optionally disposed on the walkie-talkie body 1 and the other disposed on the battery 2. They can be integrally formed into the outer shell of the walkie-talkie body 1 or the battery 2.

[0020] As attached Figure 2 As shown, a receiving groove 41 is formed inside the connector sleeve 4, and a limiting hole 42 penetrating the inside and outside of the receiving groove is provided on the side wall of the connector sleeve 4. A first electrode 61 is provided on the bottom surface inside the receiving groove 41. The first electrode 61 is electrically connected to the internal circuit of the walkie-talkie body 1 or the battery 2 fixed to the connector sleeve 4. Taking the connector sleeve 4 fixed to the walkie-talkie body 1 as an example, the first electrode 61 is electrically connected to the circuit of each functional module inside the walkie-talkie body 1.

[0021] As attached Figure 3 and 4 As shown, the outer diameter of the connector 5 is in clearance fit with the inner diameter of the receiving groove 41. The end face of the connector 5 is provided with a second electrode 62. Taking the connector sleeve 4 fixed to the walkie-talkie body 1 in the above embodiment as an example, the connector 5 should be fixedly installed in the other of the walkie-talkie body 1 or the battery 2. That is, the connector 5 needs to be fixed to the battery 2, and the second electrode 62 is electrically connected to the internal circuit of the battery 2.

[0022] A limiting pin 51 is provided on the side of the connector sleeve 4. The limiting pin 51 and the connector 5 are connected by an elastic element. The elastic force of the elastic element causes the limiting pin 51 to move elastically relative to the center of the connector 5. The elastic element can be a spring sheet 52 or other elastic parts. When the connector 5 is inserted into the receiving groove 41, and the elastic element pushes the limiting pin 51 into the limiting hole 42, the first electrode 61 and the second electrode 62 make contact and conduct. This structure can ensure automatic alignment and self-locking performance during the connection process, ensuring that the equipment maintains a durable and reliable circuit connection during dynamic use.

[0023] Continue to refer to the appendix Figure 3 and 4 The elastic element is a spring piece 52, one end of which is fixed to the connector 5, and the spring piece 52 is parallel to the axis of the connector 5. The fixing method can be that the connector 5 has a slot, and one end of the spring piece 52 is inserted into the slot. Further, a screw is inserted from the outside of the connector 5 inwards until it passes through the spring piece 52 for tightening. A limiting pin 51 is fixed to the side of the spring piece 52 facing outwards from the connector 5. The fixing method can be welding or stamping, i.e., the limiting pin 51 is a protrusion at one end of the spring piece 52. During the insertion of the connector 5 into the receiving groove 41, the inner wall of the receiving groove 41 presses against the limiting pin 51, causing the spring piece 52 to swing and deform towards the connector 5. When the limiting pin 51 corresponds to the limiting hole 42, the elastic force of the spring piece 52 returning to its original position drives the limiting pin 51 to be pushed radially outwards into the limiting hole 42, achieving simultaneous completion of mechanical locking and electrode conduction.

[0024] As attached Figure 5 As shown, the elastic element is a spring 53, with the connector 5 and the limiting pin 51 connected to its two ends respectively. During the insertion of the connector 5 into the receiving groove 41, the inner wall of the receiving groove 41 presses against the limiting pin 51, causing the spring 53 to compress and deform. When the limiting pin 51 corresponds to the limiting hole 42, the elastic force of the spring 53 restores its elasticity, pushing the limiting pin 51 radially outward into the limiting hole 42, thus simultaneously completing the mechanical locking and electrode conduction. When removing the battery 2, the limiting pin 51 is pushed inward at the limiting hole 42, causing it to disengage from the limiting hole 42 and release the locking state. Then, the connector 5 can be pulled out of the receiving groove 41. Preferably, limiting holes 42 are provided on both sides of the connector sleeve 4, and elastic elements and limiting pins 51 are provided on both sides of the connector 5 to improve the stability of the locking structure. Furthermore, when installing or removing the battery, pressing the limiting pin 51 into the receiving groove 41 simultaneously with the thumb and forefinger also improves the ease of operation.

[0025] Please refer to the appendix. Figure 4After connection, the corresponding end faces of the connector sleeve 4 and connector 5 are equipped with magnets 7 (such as neodymium iron boron magnets). When the limiting pin 51 is pushed into the limiting hole 42, 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 connector sleeve 4 and connector 5, and further prevents the connector 5 from accidentally coming loose from the connector sleeve 4.

[0026] 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 a connector sleeve 4 or connector 5 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.

[0027] In summary, the flexible connection structure of the battery 2 in this invention innovatively optimizes the reliability and wearing experience of the ear-hook walkie-talkie. Through the synergistic action of the limiting pin 51 and the elastic element, the flexible connection structure achieves automatic alignment and self-locking when the connector 5 is inserted into the connector sleeve 4, ensuring immediate and reliable contact and conduction between the first electrode 61 and the second electrode 62, guaranteeing the long-term stability of the circuit connection. When removing the battery 2, the limiting pin 51 is pushed inward at the limiting hole 42, causing it to disengage from the limiting hole 42 and release the locking state. Then, the connector 5 can be pulled out of the receiving groove 41, completing the removal of the battery 2. It is evident that the connection structure of this invention requires only a simple pressing and plugging action to simultaneously fix the battery 2 and establish circuit conduction, improving the continuous use capability of the walkie-talkie, making it particularly suitable for work scenarios requiring long-term communication.

[0028] 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.
