For ease of description, the reference orientation of this utility model is the state of the main body 100 in normal use, and the length direction of the main body 100 is the left-right direction, and the width direction is the up-down direction. The main body 100 includes a shell 1, a display screen 11, a circuit board 12, and functional units.

[0043] The aforementioned outer shell 1 is a square shell, and the outer shell 1 is the same as the outer shell of outdoor equipment and emergency equipment already sold on the market, such as the outer shell of a walkie-talkie. In this embodiment, the outer shell 1 includes two mutually overlapping front shells and rear shells, which are assembled together in a conventional manner, such as by clamping or bolting. In this embodiment, the outer shell 1 is a conventional plastic shell.

[0044] The aforementioned circuit board 12 is fixedly installed inside the housing 1, and the circuit board 12 is located on the front side of the housing 1, that is, the circuit board 12 is installed on the front housing, and the installation structure of the circuit board 12 inside the housing 1 adopts the existing conventional installation structure. For example, mounting holes are opened around the circuit board 12, and the front housing is provided with mounting posts with threaded holes corresponding to the positions of each mounting hole. Each mounting hole and each threaded hole are threaded in a one-to-one manner. The circuit board 12 integrates a main control chip, which is a conventional main control chip, such as the ME32F030 series control chip produced by National Technology.

[0045] The aforementioned display screen 11 is embedded in the front side of the housing 1. The embedding structure of the display screen 11 is a conventional mounting structure, that is, a mounting hole is provided on the front housing, and the display screen 11 is embedded in the mounting hole. In this embodiment, the signal input terminal of the display screen 11 is electrically connected to the signal output terminal of the main control chip on the circuit board 12, so as to display the corresponding content on the display screen 11. Preferably, the display screen 11 can be a touch screen, which is bidirectionally electrically connected to the main control chip, that is, the user can send control commands to the main control chip through the touch screen, and the main control chip controls the start and stop of the corresponding unit according to the sent control commands.

[0046] The aforementioned functional units include a radiation detection device and a power supply device. The radiation detection device is used to detect the radiation value of the surrounding environment, and the power supply device is used to provide power to the present invention and can also be used as a power bank.

[0047] Specifically, the aforementioned radiation detection device includes a Geiger tube 21 and a Geiger tube detection board 22 integrating a Geiger tube detection circuit. The Geiger tube detection board 22 is fixedly installed on the rear side of the outer casing 1, that is, the Geiger tube detection board 22 is fixedly installed on the rear casing of the outer casing 1, and the two are installed together using a conventional bolt assembly method. The Geiger tube 21 is located in front of the Geiger tube detection board 22 and behind the circuit board 12, and the Geiger tube 21 is located on the right side inside the outer casing 1. The Geiger tube 21 is arranged vertically, and the upper end of the Geiger tube 21 is fixedly installed on the Geiger tube detection board 22. That is, the upper side of the Geiger tube detection board 22 has two conductive holes, and the upper end of the Geiger tube 21 is connected to two conductive elements 211. The two conductive elements 211 and the two conductive holes are connected in a one-to-one manner. The ferrule tube 21 is indirectly installed in the housing 1 through a tight insertion and connection. The sampling end of the ferrule tube 21 is electrically connected to the signal input end of the ferrule tube detection board 22 through the conductive engagement of the conductive element 211 and the conductive hole. The ferrule tube detection board 22 has a conductive line embedded in it in a conventional manner between the conductive hole and the signal input end of the ferrule tube detection board 22, so that the sampling end of the ferrule tube 21 is electrically connected to the signal input end of the ferrule tube detection board 22, and the signal output end of the ferrule tube detection board 22 is electrically connected to the signal input end of the main control chip. In this way, the radiation detection device converts the collected data into radiation values ​​and transmits them to the main control chip. The main control chip can display the radiation values ​​directly on the display screen, or issue an alarm in the following manner.

[0048] The main control chip has a storage unit that stores radiation thresholds, and a warning light is embedded on the front side of the housing 1. This warning light is electrically connected to the signal output terminal of the main control chip. When the radiation detection device detects that the radiation level in the surrounding environment exceeds the threshold, the main control chip sends a warning signal to illuminate the warning light, thereby alerting the user. Preferably, a speaker 13 is installed on the front side inside the housing 1. The speaker 13 is located on the right side of the inner side of the housing 1. The speaker 13 uses a conventional mounting structure, i.e., a mounting plate 131 is fixedly installed on the front side inside the housing 1, and the two are installed together by bolts. A fixing hole is provided on the mounting plate 131, and the speaker 13 is fixedly secured in the fixing hole. A sound hole area 132 is provided on the front side of the housing 1 corresponding to the position of the speaker 13. Several sound holes are arranged sequentially in this sound hole area to facilitate sound playback. The speaker 13 is electrically connected to the signal output terminal of the main control chip. Thus, when the radiation detection device detects excessive radiation, the main control chip can also transmit a warning signal to the speaker, causing the speaker 13 to play a sound as a warning.

[0049] Preferably, a radiation detection button is installed on the front side of the housing 1. The radiation detection button is electrically connected to the signal input terminal of the main control chip, so as to facilitate the user to turn the radiation detection device on or off by means of the radiation detection button.

[0050] It is worth mentioning that the radiation detection device formed by the Geiger tube 21 and the Geiger tube detection board 22 integrated with the Geiger tube detection circuit is a radiation detection instrument that is already available on the market. The Geiger tube detection board 22 is also the circuit board used in radiation detection instruments that are already available on the market.

[0051] The aforementioned power supply device includes a solar panel, a hand-cranked generator, and a battery assembly installed inside the housing 1. The battery assembly includes a lithium battery pack 32, a battery controller, and a charging / discharging interface 31. The charging / discharging interface 31 is embedded in the lower side of the housing 1, and the charging / discharging interface 31 can be a conventional Type-C interface, USB interface, etc. In this embodiment, the charging / discharging interface 31 is a Type-C interface. The battery controller is integrated into the aforementioned main control chip, and the battery controller is a commercially available battery controller, such as the SW6201 management chip produced by Zhuhai Zhirong Technology. The lithium battery pack 32 is a commercially available high-capacity lithium battery. The charging / discharging interface 31 is bidirectionally electrically connected to the battery controller, and the lithium battery pack 32 is bidirectionally electrically connected to the battery controller. When the user charges an external handheld device, the lithium battery pack delivers electrical energy from the charging / discharging interface 31 to the handheld device for charging through the battery controller. When the user charges the lithium battery pack, the lithium battery pack delivers electrical energy from an external power supply device to the lithium battery pack through the charging / discharging interface 31 under the control of the battery controller. This power supply device can be AC ​​power or DC power with an adapter.

[0052] Preferably, a power switching button is installed on the front side of the housing 1. The power switching button is electrically connected to the signal input terminal of the main control chip and is used to switch between charging the external handheld device and charging the lithium battery pack by the power supply device.

[0053] Furthermore, the aforementioned solar energy module uses commercially available solar energy modules. For example, in this example, the solar energy module includes a solar panel 41 and a charging control circuit 40. The charging control circuit 40 is integrated in the circuit board 12. The solar panel 41 is embedded on the upper side of the outer casing 1, and the surface of the solar panel 41 occupies as much as possible on the upper side of the outer casing 1 to increase the light-receiving area of ​​the solar panel 41. The solar panel 41 is electrically connected to the power input terminal of the charging control circuit 40, and the power output terminal of the charging control circuit 40 is electrically connected to the power input terminal of the lithium battery pack. In this way, the solar panel 41 converts solar energy into electrical energy, and the electrical energy is stored in the lithium battery pack through the charging control circuit 40, thereby realizing the use of solar energy to charge the lithium battery pack, thus facilitating continuous power supply to this utility model when the sun is shining.

[0054] Furthermore, the aforementioned hand-cranked generator assembly includes a rotating component 42, an operating handle 43, and a hand-cranked generator 44. The hand-cranked generator is a commercially available small hand-cranked generator. The hand-cranked generator 44 is fixedly installed inside the housing 1 and located on the rear side of the lithium battery pack 32. The conventional hand-cranked generator 44 has a rotatable rotary input section 441. The rotating component 42 is rotatably mounted on the rear side of the housing 1. One end of the operating handle 43 is connected to the rotating component 42, and the operating handle 43 is located on the outside of the housing 1. The hand-cranked generator 44 has a rotatable rotary input section 441, which is mounted on the rotating component 42. The rotation of the rotating component 42 drives the rotary input section 441 to rotate, thereby generating electrical energy. The power output terminal of the hand-cranked generator 44 is electrically connected to the power input terminal of the lithium battery pack 32 to provide electrical energy to the lithium battery pack 32.

[0055] In detail, a fixing plate is fixedly installed on the housing of the aforementioned hand-cranked generator 44. Several fixing holes are formed around the perimeter of this fixing plate. The outer casing 1 has threaded holes corresponding to each fixing hole. Each corresponding fixing hole and threaded hole is fastened together with bolts, thus fixing the hand-cranked generator 44 inside the outer casing 1. The rotary input part 441 of the hand-cranked generator 44 faces the rear of the outer casing 1 and is arranged along the front-rear direction. A mounting hole is formed on the left side of the rear side of the outer casing 1. The rotating member 42 is rotatably disposed in this mounting hole, with its front end extending into the outer casing 1 and tightly engaging with the rotary input part 441. Specifically, a locking protrusion is integrally connected to the middle position of the rotating member 42, and a locking recess is provided on the rotary input part 441 itself. The locking protrusion and locking recess engage with each other, thus securing the rotating member 42... The rotation can drive the rotation of the rotary input unit 441. The operating handle 43 is elongated, and its left end is hinged to the rotating component 42. The left end of the operating handle 43 is hinged to the rotating component 42 through a conventional hinge structure such as a pin or a rotating shaft. For example, two mounting lugs 421 are integrally connected to the rear side of the rotating component 42. The two mounting lugs 421 are arranged opposite each other and are arranged sequentially from top to bottom. Each mounting lug 421 has a lug hole, which corresponds to each other, and the same pin is tightly inserted into each lug hole. The left end of the operating handle 43 has a shaft hole, which is sleeved on the pin. The diameter of the shaft hole is larger than the diameter of the pin. This allows the operating handle 43 to rotate with its left end as the base point, so that the operating handle 43 can be pulled up and rotated, thereby driving the rotating component 42 to rotate. Preferably, to prevent the operating handle 43 from shaking when idle, a plug-in slot 14 is provided on the right end of the rear side of the housing 1. The upper and lower side walls of the plug-in slot 14 are integrally connected with limiting strips, and the right end of the operating handle 43 is integrally connected with a plug-in block 431. When the operating handle 43 is in the retracted state, the plug-in block 431 is engaged in the corresponding plug-in slot 14. At this time, the plug-in block 431 is clamped between the two limiting strips, thereby fixing the right end of the operating handle 43 and also making it easy for the right end of the operating handle 43 to detach from the plug-in slot under the action of external force.

[0056] Preferably, to ensure that the rotating part 42 does not wobble or deviate when rotating, the mounting hole on the rear side of the housing 1 is provided with a limiting groove arranged in the circumferential direction, and a limiting slider is integrally connected to the outer circumferential surface of the rotating part 42. The limiting groove and the limiting slider slide together to limit the rotating part 42.

[0057] It should be noted that the lithium battery pack in this embodiment can be charged by solar power, power supply equipment, or hand-cranked generator. The switching between the charging methods of the solar panel, power supply equipment, and hand-cranked generator is set according to the actual situation. For example, in this embodiment, the solar panel can be charged by default, and the solar panel can be automatically disconnected when the hand-cranked generator is charging. When the power supply equipment is charging, either the solar panel or the hand-cranked generator can be automatically disconnected. Alternatively, one or more of the solar panel, hand-cranked generator, and power supply equipment can be charged together. For example, the solar panel and the hand-cranked generator can both supply power to the battery, and both use conventional low-current slow charging. An external power source can supply power to the lithium battery pack when the solar panel and the hand-cranked generator are not working. This external power source can be a conventional high-current fast charging source. It is worth mentioning that the conventional lithium battery pack in this embodiment has a charge and discharge protection mechanism. When the lithium battery pack is fully charged, it will automatically stop charging and perform charging protection.

[0058] Furthermore, a lighting lamp 51 is embedded on the left side of the aforementioned outer casing 1. The lighting lamp 51 is adjacent to the lithium battery pack 31. In this embodiment, the lighting lamp 51 is a conventional LED lamp or lamp tube. The lighting lamp 51 is equipped with a lighting button 52, which is fixedly installed on the lower side of the outer casing 1. The two are installed using conventional methods such as tight insertion and snap-fit. The lighting button 52 is electrically connected to the signal input terminal of the main control chip, and the signal output terminal of the main control chip is electrically connected to the control terminal of the lighting lamp 51, so that when the user presses the lighting button 52, the lighting lamp 51 turns on or turns off.

[0059] Furthermore, a compass 53 is fixedly installed on the upper side of the aforementioned outer casing 1. The compass 53 is located on the right side of the solar panel 41. In this embodiment, the compass 53 is a commercially available compass to facilitate direction determination outdoors.

[0060] Furthermore, the aforementioned functional unit also includes a radio function, namely, an AM / FM receiver. This AM / FM receiver can be a conventional handheld device, such as an AM / FM receiver including an FM antenna 61, an AM antenna 62, and an AM / FM chip. The FM antenna 61 and AM antenna 62 are arranged side by side, with their lengths aligned along the left-right direction of the housing 1. Both the FM antenna 61 and AM antenna 62 are located on the lower side inside the housing 1. The FM antenna 61 is located on the front side of the circuit board 12, and the FM antenna 62 is located on the rear side of the lithium battery pack 32. The AM / FM chip is integrated on the circuit board 12. The FM antenna 61 is fixedly installed in the front housing of the housing 1, and the two can be assembled using conventional methods such as bolt assembly. The AM antenna 62 is fixedly installed in the rear housing of the housing 1, and the rear housing has a receiving slot into which the AM antenna 62 is tightly inserted.

[0061] The circuit connections for FM and AM radio reception are as follows: FM antenna 61 is electrically connected to the signal input terminal of AM / FM chip via FM high-frequency amplifier circuit; AM antenna 62 is electrically connected to the signal input terminal of AM / FM chip via AM high-frequency amplifier circuit; and the signal output terminal of AM / FM chip is electrically connected to the signal input terminal of speaker 13 via audio power amplifier circuit. The FM high-frequency amplifier circuit, AM high-frequency amplifier circuit, and AM / FM chip are all integrated in the aforementioned circuit board 12. Thus, when FM antenna 61 or AM antenna 62 receives a signal, the received signal is amplified by the corresponding high-frequency amplifier circuit and then sent to AM / FM chip for demodulation. The demodulated audio is then sent to the audio power amplifier circuit (i.e., audio power amplifier circuit) for amplification, and finally, the amplified sound is played through speaker 13.

[0062] Furthermore, the front of the outer casing 1 is equipped with a rotary button 63 for adjusting the radio and an AM / FM switch button 64. The installation structure of the rotary button 63 is the same as that of the rotary button 63 used for radio tuning in conventional handheld devices, so it will not be described in detail. The rotary button 63 and the AM / FM switch button 64 are electrically connected to the signal input terminal of the main control chip, and the signal input terminal of the AM / FM chip is electrically connected to the signal output terminal of the main control chip. In this way, the AM / FM switch button 64 is used to switch the radio band, and the rotary button 64 is used to tune the frequency of the corresponding band (i.e., search for stations).

[0063] Furthermore, the aforementioned functional unit also includes an intercom function, namely, a GMRS wireless intercom device. The GMRS wireless intercom device includes a GMRS antenna 71, a microphone 15, and an intercom circuit. The GMRS antenna 71 is fixedly installed on the upper side of the outer shell 1. The GMRS antenna 71 is a commercially available GMRS antenna. A receiving recess is provided on the rear part of the upper side of the shell 1. The GMRS antenna 71 is housed in the receiving recess, and the left end of the GMRS antenna 71 is rotatably mounted on the shell 1. The rotation structure of the GMRS antenna 71 adopts the rotation structure used in the antenna of a walkie-talkie, which will not be described in detail here. The microphone 15 is fixedly installed inside the shell 1 and is fixedly installed on the mounting plate 131, facing the sound hole area. In this embodiment, the microphone 15 is located on the upper side of the mounting plate 131, and the intercom circuit is integrated on the circuit board 12.

[0064] The GMRS intercom circuit is configured as follows: it includes a high-frequency amplifier circuit, a GMRS power amplifier circuit, an RF chip, and an audio processing circuit. The GMRS antenna 71 is electrically connected to the signal input terminals of the high-frequency amplifier circuit and the RF chip in sequence. The microphone's signal output terminal is electrically connected to the signal input terminal of the RF chip. The RF chip's signal output terminal is electrically connected to the signal input terminals of the audio processing circuit and the GMRS power amplifier circuit, respectively. The audio processing circuit's signal output terminal is electrically connected to the signal input terminal of the audio power amplifier circuit. The GMRS power amplifier circuit's signal output terminal is electrically connected to the GMRS antenna 71. The RF chip's signal input terminal is electrically connected to the signal output terminal of the main control chip. In this embodiment, the RF chip can be a chip with modulation / demodulation and audio processing functions, such as the commercially available BK4829 intercom transceiver RF chip or the Si473x series chip.

[0065] In this way, during transmission, sound is received through the microphone and sent to the radio frequency chip. After processing by the radio frequency chip, the frequency-modulated GMRS radio frequency signal is output. After being amplified by the GMRS power amplifier circuit, it is transmitted out from the GMRS antenna 71. During reception, the GMRS antenna 71 receives the signal, which is amplified by the high-frequency amplifier circuit and sent to the radio frequency chip. After being processed and demodulated by the radio frequency chip, the audio signal is sent to the audio processing circuit and then sent to the speaker for playback.
