Description

Technical Field

[0001] This invention relates to the field of walkie-talkie technology, and in particular to a waterproof walkie-talkie holder. Background Technology

[0002] A walkie-talkie is a two-way mobile communication tool that allows communication without any network support or call charges, making it suitable for relatively fixed and frequent communication situations. There are three main types of walkie-talkies: analog walkie-talkies, digital walkie-talkies, and IP walkie-talkies. Walkie-talkies are terminal devices for trunked radio communication; they can serve not only as terminal devices for trunked radio communication but also as a specialized wireless communication tool in mobile communication.

[0003] Existing walkie-talkies typically lack waterproofing. In rainy weather or if accidentally dropped into water, water can easily seep into the device, damaging it and reducing its lifespan. Furthermore, existing walkie-talkie antennas are simply cylindrical, serving only to receive signals. Since walkie-talkies need to be carried even when not in use, their large size makes them unsuitable for pockets, and the mounting brackets add to their weight, making them inconvenient to carry. While some waterproof walkie-talkies have emerged to address this, such as the Chinese patent document CN201920114402.2 which discloses a multi-functional waterproof walkie-talkie, including a housing, a display screen on the front panel of the housing, a speaker on the front panel of the housing above the display screen, an infrared sensor on the front panel of the housing next to the speaker, a power button panel on the front panel of the housing below the display screen, a microphone on the front panel of the housing below the power button panel, an antenna hinged to the upper side of the housing, a frequency tuning knob on the upper side of the housing, a charging port on the lower side of the housing, a USB port on the lower side of the housing, a battery inside the housing, a waterproof cover hinged to the side of the housing and fitting with the front panel, and a walkie-talkie system inside the housing, this invention, while possessing a certain degree of waterproofing, still allows water to seep into the charging port and USB port, achieving only a slightly temporary waterproofing effect in a simple sense, and its waterproof performance is not ideal. Summary of the Invention

[0004] Therefore, in view of the above problems, the present invention proposes a waterproof walkie-talkie with reasonable structure, low cost, strong waterproof performance, can be charged without plugging and unplugging charging structure, is easy to use, and has a small size.

[0005] To solve this technical problem, the present invention adopts the following solution: a waterproof walkie-talkie, including an earphone strap, a charging base, a walkie-talkie housing, a circuit board and a battery disposed within the walkie-talkie housing. A first magnet is provided on one inner wall of the walkie-talkie housing. A first, second, third, and fourth conductor post are sealed and passed through the side of the walkie-talkie housing where the first magnet is located. The earphone strap audio input / output interface of the circuit board is electrically connected to the ends of the first and second conductor posts located inside the walkie-talkie housing, respectively. The radio frequency transceiver antenna interface of the circuit board is electrically connected to the ends of the first and second conductor posts located inside the walkie-talkie housing, respectively. The positive and negative terminals of the battery charging connector are electrically connected to the ends of the third and fourth conductor posts located inside the walkie-talkie housing, respectively. The earphone strap includes a strap body, input interfaces at both ends of the strap body, and an earphone speaker. A second magnet with opposite polarity and compatible with the first magnet in the walkie-talkie housing is provided on the input interface of the earphone strap. A conductor post is also passed through the input interface of the earphone strap, respectively connected to the first and second conductor posts on the walkie-talkie housing. The fifth and sixth lead wires are located on the outer side of the walkie-talkie housing and are connected in a one-to-one correspondence. The earphone speaker is electrically connected to the fifth and sixth lead wires at the end of the earphone strap via the strap body. The length of the earphone strap is the same as the length of the strip antenna for the corresponding frequency band. The RF transceiver antenna interface of the circuit board is connected to the fifth and sixth lead wires via the first and second lead wires. One wire in the strap body connected to the earphone speaker is used as an antenna to transmit RF signals and receive RF signals. The upper part of the charging base is provided with a third magnet with the opposite polarity to the first magnet of the walkie-talkie housing. The upper surface of the charging base is provided with two power output terminals, and the two power output terminals of the charging base are respectively connected to the third and fourth lead wires on the outer side of the walkie-talkie housing. The charging base is attracted by the opposite polarity of the third magnet and the first magnet of the walkie-talkie housing, so that the two power output terminals of the charging base are respectively connected to the third and fourth lead wires of the walkie-talkie housing to charge the battery inside the walkie-talkie housing.

[0006] Furthermore, the charging base includes a base body, a charging circuit board disposed within the base body, a third magnet, a power connection wire, and two power output terminals. The third magnet is disposed on the upper part of the base body, corresponding to the position of the first magnet on one side of the walkie-talkie housing. The two power output terminals are electrically connected to the power output of the charging circuit board. The two power output terminals are respectively disposed on the upper surface of the base body. The input end of the power connection wire is connected to the power supply, and the output end of the power connection wire passes through the base body and is electrically connected to the power input of the charging circuit board.

[0007] Furthermore, one side of the walkie-talkie housing has an inwardly recessed positioning groove in the area where the first magnet, first conductor post, second conductor post, third conductor post, and fourth conductor post are located.

[0008] Furthermore, the inner wall of the walkie-talkie housing is provided with a waterproof sealing ring or a waterproof adhesive layer around the first, second, third, and fourth conductor posts.

[0009] Furthermore, the upper surface of the walkie-talkie housing is provided with an LED electronic display screen, which is connected to and controlled by the circuit board.

[0010] Furthermore, the input interface of the earphone strap is provided with the free ends of the second magnet, the fifth conductor post and the sixth conductor post being protruding ends that can be adapted to be embedded in the positioning groove of the walkie-talkie housing, and the free ends of the fifth conductor post and the sixth conductor post both protrude 1mm-3mm from the end face.

[0011] Furthermore, the first magnet inside the walkie-talkie housing includes two spaced-apart magnetic posts, and the first, second, third, and fourth wire posts pass through the walkie-talkie housing between the two magnetic posts.

[0012] Furthermore, the earphone strap also includes an air duct earplug, the inlet of which is connected to the earphone speaker of the earphone strap.

[0013] By adopting the aforementioned technical solution, the beneficial effects of the present invention are as follows: By setting a first magnet in the walkie-talkie housing and sealing and passing through the first, second, third, and fourth conductor posts, the audio input / output interface of the earphone strap on the main board is electrically connected to the ends of the first and second conductor posts located inside the walkie-talkie housing, respectively. The RF transceiver antenna interface of the main board is also electrically connected to the ends of the first and second conductor posts located inside the walkie-talkie housing, respectively. The frequency programming of the main board adopts the factory-set fixed frequency, eliminating the need for a frequency programming interface. If frequency adjustment is required, it can be returned to the factory for adjustment. The positive and negative terminals of the battery charging connector are electrically connected to the ends of the third and fourth conductor posts located inside the walkie-talkie housing, respectively. A conductor in the earphone speaker strap acts as an antenna to transmit and receive RF signals. The earphone strap is equipped with corresponding and matching fifth and sixth conductor posts. The input interface of the earphone strap is attracted by the second magnet in conjunction with the first magnet on the walkie-talkie housing, so that the fifth and sixth conductor posts of the earphone strap are respectively connected to the earphone housing. The first and second lead wires are connected to enable voice reception and playback on the walkie-talkie. This eliminates the need for a plug-in charging port, headphone jack, USB connector, speaker, microphone, and PTT transmitter button. The walkie-talkie of this invention has no water ingress or leakage points, boasts a reasonable structure, excellent dustproof performance, superior waterproofing, ease of use, smaller size, and lower manufacturing cost. Furthermore, a contact-type charging base is incorporated, where the third magnet of the charging base engages with the first magnet of the walkie-talkie housing. When charging is required, the two power output terminals of the charging base connect to the third and fourth lead wires of the walkie-talkie housing to charge the battery inside. This eliminates the need for a plug-in charging connector, saving space for antenna installation and reducing the space required for the charging port, microphone, PTT button, and headphone jack audio interface. This significantly reduces the overall length of the walkie-talkie housing, allowing for faster installation and enabling the creation of a simple, mini, waterproof walkie-talkie for receiving and playing voice messages. With further design, an inwardly recessed positioning groove is provided on one side of the walkie-talkie housing in the area where the first magnet, first guide post, second guide post, third guide post, and fourth guide post are located. The free ends of the second magnet, fifth guide post, and sixth guide post of the earphone strap input interface are protruding ends that can be fitted into the positioning groove of the walkie-talkie housing, making the contact connection between the earphone strap and the walkie-talkie more stable. An LED electronic display screen is provided on the upper surface of the walkie-talkie housing. This LED electronic display screen is connected to and controlled by the circuit board, so that the walkie-talkie can display welcoming messages such as "Welcome". Attached Figure Description
