Description

Technical Field

[0001] The present invention relates to the technical field of communication devices, and particularly to a special communication walkie-talkie. Background Art

[0002] In the modern communication field, as an important instant communication device, the walkie-talkie is widely used in various field work scenarios, such as logistics distribution, security patrol, emergency rescue, outdoor exploration, etc. With its advantages of instant communication and group call, it provides convenience for the communication and cooperation of field personnel, and plays a key role in improving work efficiency and ensuring the smooth execution of tasks. However, with the continuous expansion of application scenarios and the increasing improvement of work requirements, a series of problems that need to be solved urgently have emerged in the actual field use of existing walkie-talkies.

[0003] Currently, when field personnel use a walkie-talkie, the common wearing method is to hang it on the chest or shoulder. However, in this way, the length of the walkie-talkie antenna will limit the movement of the human body. In some work scenarios that require frequent turning, bending, climbing or rapid movement, the antenna is likely to affect work efficiency and may also cause damage to the walkie-talkie or injury to personnel.

[0004] When the walkie-talkie is hung on the chest or shoulder, the distance between the conversation microphone and the user's mouth is relatively far. In a noisy field work environment, this makes it difficult for the walkie-talkie to clearly receive the user's voice, resulting in a decline in communication quality, inaccurate information transmission, and easy occurrence of work mistakes or delays.

[0005] To improve the sound reception effect, some field personnel choose to wear wired or wireless headphones in combination with the walkie-talkie. However, when it comes to some field work involving strenuous exercise, the headphones are very easy to fall off and cause damage, and the personnel also have to monitor both the headphones and the microphone at all times, increasing the burden on the personnel and distracting their attention. Therefore, a special communication walkie-talkie is proposed to solve the above-mentioned problems. Summary of the Invention

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a communication dedicated interphone, which has the following beneficial effects:

[0021] 1. For this communication dedicated interphone, the communication antenna can be stored in the storage groove. The pressing surface on the top edge of the connecting groove presses and connects the electrode sheet, so that it is disconnected from the antenna electrode to avoid electric leakage. After being stored in place, the locking rod of the locking part is inserted into the locking groove of the communication antenna to fix the antenna and prevent it from sliding out accidentally. When in use, unlocking can pull out the antenna. This design avoids the influence of the too long antenna on the limb activities of personnel, reduces the risks of the interphone damage and personnel injury caused by the antenna, and improves the action convenience and work efficiency of field personnel in complex working scenarios.

[0022] 2. For this communication dedicated interphone, in a noisy outdoor environment, when the communication antenna is stored, the contact infrared sensor is triggered to activate the electrode sheet one. The processor controls the analog switch to cut off the original antenna circuit, and at the same time controls the switching part to work. The sliding cover rises, and the electrode sheet two abuts against the electrode sheet one to be energized, and the bendable microphone is activated. The user can adjust the bendable gooseneck tube to adjust the microphone nozzle close to the mouth. Compared with the fixed microphone position of the traditional interphone, it is more conducive to sound collection, effectively improves the sound reception quality, reduces the inaccurate information transmission situation, and reduces the probability of work mistakes and delays.

[0023] 3. This dedicated communication walkie-talkie abandons the traditional way of using it with an earphone, avoiding the problem that the earphone is prone to falling off and being damaged during strenuous exercise. Through components such as a built-in bendable microphone and loudspeaker, the optimization of the voice collection and playback functions is realized. Field staff do not need to monitor the earphone and microphone all the time, reducing the burden and enabling them to focus more on the work task itself, improving work concentration and overall efficiency.

[0024] 4. When the sliding cover of this dedicated communication walkie-talkie is raised, it can not only switch the microphone but also protect the loudspeaker and communication microphone of the communication walkie-talkie body, reducing the damage to these components caused by external factors such as collision and dust, extending the service life of the walkie-talkie, and reducing the maintenance cost.

[0025] 5. This dedicated communication walkie-talkie uses a spare antenna connected by a universal joint and electrically connected to the processor. When the communication antenna is retracted or fails to work properly, the spare antenna can be put into use at any time. Users can freely adjust the direction of the spare antenna according to the actual signal reception situation to ensure stable communication signals in various complex environments, ensuring the continuity and reliability of communication, and avoiding communication interruption caused by antenna problems and affecting work progress.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1-8 , the present invention provides a technical solution: a communication dedicated walkie-talkie, including a communication walkie-talkie body 1, a communication part 2 is arranged on the communication walkie-talkie body 1 for storing and releasing the antenna. The communication part 2 includes a communication antenna 21. A connection groove 22 is opened on one side of the bottom end of the communication antenna 21. An antenna electrode is arranged on the inner wall of the connection groove 22. An insulating sheet 23 is integrally connected to one side of the outer wall of the communication antenna 21. A pressing surface 24 is arranged on the top edge of the connection groove 22. The pressing surface 24 is a slope structure. Slide blocks 25 are fixedly connected to both sides of the bottom end of the communication antenna 21. A storage groove 26 is opened on one side of the top of the communication walkie-talkie body 1. Slide grooves 27 are opened on both sides of the inner wall of the storage groove 26. The communication antenna 21 is slidably connected to the inner wall of the storage groove 26. The two slide blocks 25 are respectively slidably connected to the inner walls of the two slide grooves 27. An L-shaped groove 28 is opened inside the communication walkie-talkie body 1. One end of the L-shaped groove 28 is communicated with the storage groove 26.

[0037] In the present invention, a disconnection part 3 is arranged in the L-shaped groove 28 for switching the electrical connection and disconnection of the antenna. The disconnection part 3 includes a partition 31 fixedly connected to the inner wall of the L-shaped groove 28. A through hole 32 is opened in the middle of the partition 31. One end inner wall of the L-shaped groove 28 is slidably connected with a connection electrode piece 33. A first spring 34 is elastically connected between the partition 31 and the connection electrode piece 33. A cable 35 is fixedly connected to the connection electrode piece 33. The end of the cable 35 passes through the through hole 32 and extends downward along the other end inner wall of the L-shaped groove 28. The top edge of the end of the connection electrode piece 33 away from the cable 35 is a bevel structure. The connection electrode piece 33 abuts against the inner wall of the connection groove 22 and is electrically connected to the antenna electrode. When the communication antenna 21 slides downward into the storage groove 26, the pressing surface 24 presses the bevel of the connection electrode piece 33, prompting the connection electrode piece 33 to enter the L-shaped groove 28 and disconnect from the antenna electrode. Subsequently, the connection electrode piece 33 is only abutted against the insulating sheet 23 by the elastic force of the first spring 34 to avoid electric leakage.

[0038] In this embodiment, a locking part 4 is arranged in the storage groove 26 for locking the antenna in place after storage. The locking part 4 includes a rod groove 41 opened inside the communication interphone body 1. A locking rod 42 slidably penetrates through the inner wall of the rod groove 41. One end of the locking rod 42 extends into the storage groove 26, and the other end of the locking rod 42 extends outside the communication interphone body 1 and is fixedly connected with a dial 43. The dial 43 can be manually adjusted to lock and unlock the antenna. A second spring 44 is elastically connected between the outer wall of the locking rod 42 and the inner wall of the rod groove 41. A locking groove 45 corresponding to the locking rod 42 is opened on the communication antenna 21.

[0039] It should be noted that an installation part 6 is arranged on the front of the communication interphone body 1 for installing protective tools and an adjustable microphone. The installation part 6 includes two adjustment grooves 61 symmetrically opened on both sides of the front of the communication interphone body 1. Two hanging pieces 62 are symmetrically installed on the top of the front of the communication interphone body 1. An electrode piece one 63 is installed on one side of the front of the communication interphone body 1. A contact infrared sensor 5 is installed on the inner wall of the storage groove 26. The contact infrared sensor 5 is electrically connected to the electrode piece one 63. The contact infrared sensor 5 fits the connection groove 22 of the stored communication antenna 21 to trigger a contact electrical signal to activate the electrode piece one 63. A processor 8 is installed inside the communication interphone body 1. A microprocessor Arduino is set as the core processing unit in the processor 8, and a CD4066 analog switch chip component is used to construct a switching circuit. The processor 8 is electrically connected to the contact infrared sensor 5. The extended end of the cable 35 is fixedly connected to and electrically connected to the processor 8. When the contact infrared sensor 5 is triggered, the cable 35 is not powered on.

[0040] A switching part 7 is provided on the adjustment groove 61 for switching the usage permissions of the microphone and antenna of the walkie-talkie. The switching part 7 includes a sliding cover 71. The sliding cover 71 is of a U-shaped structure. The two ear ends of the sliding cover 71 are respectively slidably connected to the inner walls of the two adjustment grooves 61. The top of the ear end of the sliding cover 71 and the top of the inner wall of the corresponding adjustment groove 61 attract each other with opposite genders. After the sliding cover 71 rises, it is adsorbed and fixed without falling. A loudspeaker 72 is installed on the sliding cover 71. On one side of the inner wall of the sliding cover 71, an electrode sheet two 73 corresponding to the electrode sheet one 63 is installed. The electrode sheet one 63 adopts a phosphor bronze spring sheet electrode. A bendable microphone 74 is installed on the electrode sheet two 73. After the sliding cover 71 rises and is fixed, the electrode sheet two 73 abuts against the electrode sheet one 63 to directly conduct electricity. The bendable microphone 74 includes a bendable gooseneck tube and a microphone nozzle. The use position of the microphone can be freely adjusted by using the bendable gooseneck tube. The bendable gooseneck tube can be wound around the hanging piece 62 for storage.

[0041] It should be noted that a speaker and a communication microphone are provided on the front of the communication walkie-talkie body 1. After the sliding cover 71 rises, it plays a role in protecting the speaker and microphone of the communication walkie-talkie body 1. Both the speaker and the communication microphone are electrically connected to the processor 8. A channel knob and a switch volume knob are provided on the top of the communication walkie-talkie body 1. Both the channel knob and the switch volume knob are electrically connected to the processor 8. A battery 9 is installed inside the communication walkie-talkie body 1. The battery 9 is electrically connected to the processor 8. Anti-slip sheets 10 are installed on both sides of the outer wall of the communication walkie-talkie body 1. The anti-slip sheets 10 improve the stability during grasping. A spare antenna is installed on one side of the outer wall of the communication walkie-talkie body 1. The spare antenna is connected by a universal joint and is electrically connected to the processor 8. The spare antenna can freely adjust the direction to replace the communication antenna 21 after storage for use.

[0042] Working principle: The communication antenna 21 can slide in the storage groove 26. The slider 25 at its bottom end cooperates with the chute 27 on the inner wall of the storage groove 26 to ensure stable sliding. When the antenna needs to be stored, the communication antenna 21 is slid down into the storage groove 26. At this time, the pressing surface 24 (bevel structure) on the top edge of the connecting groove 22 will squeeze the bevel of the connecting electrode sheet 33, so that the connecting electrode sheet 33 overcomes the elastic force of the spring one 34 and enters the L-shaped groove 28, thus disconnecting from the antenna electrode to avoid electric leakage. After that, the connecting electrode sheet 33 will only abut against the insulating sheet 23. After storage in place, the dial 43 of the locking part 4 is pushed, and the locking rod 42 extends out under the action of the spring two 44 and inserts into the locking groove 45 on the communication antenna 21 to fix the antenna and prevent it from sliding out accidentally. When in use, the dial 43 is toggled to retract the locking rod 42, and the antenna can be pulled out of the storage groove 26. The connecting electrode sheet 33 is re-electrically connected to the antenna electrode under the elastic force of the spring one 34 to ensure the communication function.

[0043] After the contact infrared sensor 5 on the inner wall of the storage groove 26 fits against the connection groove 22 and triggers a contact electrical signal after the communication antenna 21 is stored in place, it activates the first electrode piece 63. The first electrode piece 63 is electrically connected to the processor 8. The processor 8 controls the analog switch circuit (constructed by the CD4066 analog switch chip). When the contact infrared sensor 5 is triggered, the processor 8 controls the analog switch to cut off the power supply of the cable 35, and at the same time controls the switching part 7 to work. The sliding cover 71 of the switching part 7 can slide in the adjustment groove 61, and the top of its ear end is attracted by the opposite sex to the top inner wall of the adjustment groove 61 and can be adsorbed and fixed after rising. When the sliding cover 71 rises, the second electrode piece 73 abuts against the first electrode piece 63 to conduct electricity. At this time, the bendable microphone 74 (including a bendable gooseneck tube and a microphone nozzle) is activated. The user can adjust the position of the microphone nozzle by adjusting the bendable gooseneck tube to make it closer to the mouth and improve the sound collection effect. When the communication antenna 21 is not stored, the contact infrared sensor 5 is not triggered, and the analog switch enables the original communication microphone to work normally.

[0044] When in normal use and the communication antenna 21 is not stored, the user speaks to the communication microphone on the front of the communication walkie-talkie body 1. The sound signal is collected and transmitted to the processor 8. The processor 8 processes the signal and then sends it out through the communication antenna 21 of the communication unit 2. When the communication antenna 21 is stored and the bendable microphone 74 is activated, the user speaks to the microphone nozzle. The sound signal is collected by the bendable microphone 74 and transmitted to the processor 8 through the second electrode piece 73 and the first electrode piece 63, and then is controlled by the processor 8 to be sent out through the spare antenna. When receiving a signal, the communication antenna 21 or the spare antenna receives the signal and transmits it to the processor 8. After the processor 8 processes it, the sound signal is sent to the speaker for playback. If the environment is noisy, the sound playback effect can also be enhanced through the loudspeaker 72 on the sliding cover 71.

[0045] After the communication antenna 21 is stored, the spare antenna can be used for communication. The spare antenna is connected by a universal joint and can be freely adjusted in direction, which is convenient for the user to adjust its angle according to the actual signal reception situation to achieve the best reception effect. The spare antenna is electrically connected to the processor 8 and undertakes the task of signal transmission and reception when the communication antenna 21 cannot work properly or is stored, ensuring that the communication function of the walkie-talkie is not affected.
