[0026] like Figure 1 and Figure 2As shown, one embodiment of this application discloses an outdoor survival whistle, which includes a housing 10, a power supply 20, a control board 30, a pressing component 40, a sound component 50, and a light-emitting component 60. The housing 10 has an installation chamber 11. The power supply 20 and the control board 30 are both located in the installation chamber 11. The power supply 20 is electrically connected to the control board 30, and a step-up transformer 31 is provided on the control board 30. The pressing component 40 is located in the housing 10 and is electrically connected to the control board 30. The sound component 50 and the light-emitting component 60 are both located in the housing 10. The sound component 50 is electrically connected to the step-up transformer 31, and the light-emitting component 60 is electrically connected to the control board 30.

[0027] The outdoor survival whistle disclosed in this embodiment can be manufactured with a shell 10 made of corrosion-resistant and stable materials such as metal or plastic to increase the service life of the shell 10 and adapt to the changing outdoor environment. The shell 10 can be divided into two parts: a front shell and a rear shell. The front shell and the rear shell are snapped together and the assembly gap is filled with a waterproof sealing ring to form a complete mounting chamber 11, so as to facilitate the installation of electrical components in the mounting chamber 11. The shell 10 plays a protective and support role.

[0028] In this embodiment, power is provided by a power source 20, which can be a storage battery, lithium battery, dry cell battery, etc. To increase the utilization rate of the power source 20, a rechargeable battery can be used. Providing power through a portable power source 20 improves portability, allowing the outdoor survival whistle to be used anytime and anywhere in the wild, thus increasing its flexibility.

[0029] The control board 30 disclosed in this embodiment includes, but is not limited to, a printed circuit board. Wires are soldered onto the control board 30 to connect to the power supply 20, the pressing component 40, the sound component 50, and the light-emitting component 60, respectively, so that the circuit of the entire device is complete and centrally controlled by the control board 30, so as to efficiently realize the functions of light emission and sound emission.

[0030] The pressing component 40 disclosed in this embodiment includes, but is not limited to, a mechanical button or a touch button, which can generate a signal by sensing the pressing pressure. As a triggering structure, the pressing component 40 is simple to operate and does not require continuous operation, thus facilitating use in outdoor emergencies. Specifically, in an emergency, the user only needs to take out the outdoor survival whistle and press the mechanical button to simultaneously activate the sound component 50 and the light component 60, thereby sending out a distress signal. It is evident that the outdoor survival whistle disclosed in this embodiment is simple to operate, more adaptable to sudden situations, and has good application prospects in the wild.

[0031] Specifically, when the pressing component 40 is subjected to pressure, a pressure signal is generated and transmitted to the control board 30. When the control board 30 receives the pressure signal, it controls the sound component 50 and the light-emitting component 60 to start, thereby achieving the effects of emitting light and sound. In other words, the outdoor survival whistle disclosed in this embodiment only requires a simple pressing operation to continuously emit a distress signal, replacing the traditional blow-type whistle, reducing the difficulty of operation, facilitating use in the wild, increasing the chances of rescue, and adapting to emergency situations.

[0032] In this embodiment, a step-up transformer 31 is provided on the control board 30 to regulate the power supply voltage of the sound component 50, raising the power supply voltage of the sound component 50 to approximately 80V, thereby increasing the output volume. Therefore, the outdoor survival whistle in this embodiment can be set to different working modes, improving its flexibility of use. It can effectively play a role in transmitting distress signals in a timely manner, whether in open plains or rugged mountainous areas.

[0033] like Figure 2 and Figure 3 As shown, in another embodiment of this application, the housing 10 is provided with a first opening 12 communicating with the mounting chamber 11; the sound component 50 includes a speaker 51 and a waterproof and sound-permeable membrane 52, the speaker 51 is disposed in the first opening 12; the rear side of the speaker 51 is provided with an end, the end is used to connect a wire to the step-up transformer 31; the front side of the speaker 51 is provided with the waterproof and sound-permeable membrane 52.

[0034] The speaker 51 disclosed in this embodiment is a loudspeaker that converts electrical energy into sound waves and amplifies them to propagate over long distances. The speaker 51 is mounted on the housing 10 and can be fixed within the first opening 12 by snap-fitting, welding, or adhesive to maintain stability. A waterproof and sound-permeable membrane 52 is provided to prevent sewage from entering the speaker 51 or the housing 10 through the first opening 12, thus preventing circuit failures or corrosion and extending the service life of the outdoor survival whistle.

[0035] Specifically, as another embodiment of this application, the waterproof and sound-permeable membrane 52 is disclosed as a porous polytetrafluoroethylene film or a thermoplastic polyurethane film. The waterproof and sound-permeable membrane 52 adopts a microporous structure design, possessing waterproof, dustproof, breathable, and sound-permeable functions, and can be used in diverse outdoor environments.

[0036] For example Figure 3As shown, in another embodiment of this application, the housing 10 is provided with two second openings 13 communicating with the mounting chamber 11; the light-emitting component 60 includes a base plate 61 and two beacon light sources 62, the base plate 61 is electrically connected to the control board 30; the two beacon light sources 62 are spaced apart on the base plate 61; and the beacon light sources 62 are inserted into the second openings 13.

[0037] The beacon light source 62 disclosed in this embodiment includes, but is not limited to, high-brightness optical devices such as LED beads and laser emitters. The beacon light source 62 keeps flashing, which is beneficial for identification in complex and dimly lit environments in the field. The base plate 61 is used to support the two beacon light sources 62 and acts as a converter; printed circuits can be set on the base plate 61 to transfer the electrical signals of the control board 30 to the two beacon light sources 62.

[0038] Specifically, a second opening 13 is provided to expose the signal light source, which improves the light emission effect and facilitates light propagation. The size of the signal light source matches the diameter of the second opening 13, reducing assembly gaps and increasing product integrity. This not only enhances stability but also prevents impurities, dust, and sewage from entering the housing 10.

[0039] For example Figure 3 As shown, in another embodiment of this application, the outdoor survival whistle also includes an indicator light component 70, which is electrically connected to the control board 30; the housing 10 is provided with a plurality of third openings 14 communicating with the mounting chamber 11; the indicator light component 70 includes a plurality of LED beads 71 ​​and a plurality of light guides 72, the LED beads 71 ​​being disposed on the control board 30; the light guides 72 being disposed on the control board 30 and covering the LED beads 71; and the third openings 14 are positioned directly opposite the light-emitting surface of the light guides 72, the light guides 72 being used to guide the light emitted by the LED beads 71 ​​out of the third openings 14.

[0040] In this embodiment, the remaining battery power can be displayed via the indicator light component 70 to remind the user to charge the device in time. The LED beads 71 ​​include, but are not limited to, light-emitting diode (LED) beads. Multiple LED beads 71 ​​are spaced apart on the control board 30, and light is guided by the light guide component 72. The user can observe the light emission from the third opening 14 to obtain battery power information. Specifically, the remaining battery power can be indicated by the number of lit LED beads 71.

[0041] For example Figure 3As shown in another embodiment of this application, the housing 10 is provided with a fourth opening 15 communicating with the mounting chamber 11; the control board 30 is provided with an external terminal 32, which is positioned opposite the fourth opening 15 for connecting a data cable or charging cable. In this embodiment, a power supply 20 is used for power supply, but the power supply 20 has limited capacity. The fourth opening 15 is provided on the housing 10 to assemble the external terminal 32, exposing the connection port of the external terminal 32 for connecting wires. The external terminal 32 can charge the power supply 20; the external terminal 32 can be a USB interface, a Lightning interface, or a wireless charging interface.

[0042] For example Figure 2 and Figure 3 As shown, in another embodiment of this application, the housing 10 is disclosed to include an outer shell 16, a clamping plate 17, and a torsion spring 18. The outer shell 16 disclosed in this embodiment may be composed of the aforementioned front shell and rear shell. The outer shell 16 is hollow, forming the mounting chamber 11. Furthermore, a connecting seat 161 is provided on the outer surface of the outer shell 16, and a rotatable shaft 162 is provided on the connecting seat 161. The clamping plate 17 is rotatably sleeved on the shaft 162. The torsion spring 18 is sleeved on the shaft 162 and is used to abut against the clamping plate 17.

[0043] Specifically, in this embodiment, the first opening 12 and the second opening 13 can be located on the front of the outer casing 16, the third opening 14 and the fourth opening 15 can be located on the side of the outer casing 16, and the connecting seat 161 is located on the rear of the outer casing 16. A shaft 162 is mounted on the connecting seat 161 to connect the clamping plate 17, so that the clamping plate 17 maintains a rotational tendency toward the surface of the outer casing 16 under the push of the torsion spring 18. In use, by opening the clamping plate 17, the outdoor survival whistle can be hung on a belt, waist belt, shoulder strap, or other similar position, and held stable by the clamping plate 17.

[0044] For example Figure 3 As shown, in another embodiment of this application, a first anti-slip rubber block 163 is provided on the side of the outer shell 16 facing the clamping plate 17. A second anti-slip rubber block 171 is provided on the clamping plate 17 at a position opposite to the first anti-slip rubber block 163.

[0045] In outdoor sports environments, survival whistles are constantly in a bumpy state, making them prone to loosening. By using the first anti-slip rubber block 163 and the second anti-slip rubber block 171, the surface friction coefficient is increased, allowing the survival whistle to be fixed more securely and reducing the risk of accidental drop.

[0046] Specifically, as another embodiment of this application, the first anti-slip block 163 is disclosed to be any one of a rubber block, a latex block, or a silicone block, or the second anti-slip block 171 is any one of a rubber block, a latex block, or a silicone block. In this embodiment, the first anti-slip block 163 and the second anti-slip block 171 are manufactured using materials with good stability, durability, and corrosion resistance, such as rubber, latex, and silicone, which can reduce costs and extend service life.

[0047] Specifically, as another embodiment of this application, a control method for an outdoor survival whistle is disclosed, applied to any of the outdoor survival whistles described above; wherein, the control method includes: Step S10: Acquire the start signal; Step S20: Determine the sound emission mode based on the activation signal; Step S30: If the sound emission mode is a long-term sound emission mode, then the sound emission frequency, light-up frequency, and working duration are determined based on the current remaining power value; wherein, the working duration includes the continuous working time of the sound component 50 and the continuous working time of the light-emitting component 60.

[0048] The outdoor survival whistle disclosed in this embodiment can automatically determine the sound mode based on the activation signal and select the corresponding sound frequency, light frequency, and working duration to enhance its adaptability in outdoor environments. Specifically, in outdoor emergencies, users may not be able to maintain operational actions for an extended period. Therefore, once the long-duration sound mode is activated, the sound frequency and light frequency are automatically calculated to balance alarm functionality and working time, allowing the device to remain continuously operational for a certain period to facilitate search and rescue personnel. It is evident that the control method disclosed in this embodiment is simple, enabling the outdoor survival whistle to operate automatically, improving ease of use, and facilitating its adaptation to outdoor environments.

[0049] Specifically, as another embodiment of this application, the working time is disclosed to be greater than or equal to 72 hours. In emergency situations, the 72 hours following an accident are the golden rescue time. Therefore, in this embodiment, the working time of the outdoor survival whistle is adjusted to at least 72 hours to ensure continuous light and sound emission during the golden rescue time, making it easier for rescuers to search.

[0050] Specifically, as another embodiment of this application, the activation signal is disclosed to include a short press signal, a continuous press signal, and a long press signal; the step of determining the sound mode based on the activation signal specifically includes: If the activation signal is a continuous press signal, then the sound mode is set to long-duration sound mode; If the activation signal is a long press signal, then the sound mode is set to the preset sound mode; If the activation signal is a short press signal, then the sound mode is set to short-time sound mode.

[0051] In actual use, there may be general use cases and emergency use cases outdoors. Setting different working modes according to different situations can help improve the flexibility of equipment use and increase efficiency.

[0052] Specifically, in this embodiment, when the pressing component 40 is pressed briefly for 1-2 seconds, a short press signal is generated; when it is pressed briefly two or more times for 1-2 seconds, a continuous press signal is generated; and when it is pressed for a long time of 3 seconds or more, a long press signal is generated. Users only need to press the pressing component 40 according to the actual situation to adjust the operating frequency and duration of the sound component 50 and the light-emitting component 60, making it convenient to use.

[0053] Specifically, as another embodiment of this application, after disclosing the step of determining the sound mode based on the activation signal, it further includes: If the sound emission mode is a short-time sound emission mode, the sound component 50 is activated according to the rated sound emission frequency, and the total sound emission duration is 1-5 seconds. If the sound mode is a preset sound mode, the sound component 50 is activated according to the preset sound frequency, and the total sound duration is 1-5 seconds; wherein, the maximum value of the preset sound frequency is the rated sound frequency of the sound component 50.

[0054] In outdoor environments, under normal conditions, the operator can use the outdoor survival whistle as a tool for real-time information transmission. Specifically, when it is necessary to report real-time location, a brief press of the whistle will produce a short-lived sound, allowing companions to receive real-time location information. Additionally, because battery life needs to be considered during outdoor use, a custom sound power level lower than the rated sound power can be preset. When in the preset sound mode, the whistle will emit a sound at this custom power level, thereby extending the device's battery life.

[0055] As another embodiment of this application, a terminal is disclosed, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the control method of the outdoor survival whistle as described above.

[0056] As another embodiment of this application, a computer-readable storage medium is disclosed, wherein a computer program is stored on the computer-readable storage medium; when the computer program is processed and executed, it implements the steps of the control method of the outdoor survival whistle as described above.

[0057] It should be understood that various parts of this application can be implemented using hardware, software, firmware, or a combination thereof. In the above embodiments, multiple steps or methods can be implemented using software or firmware stored in memory and executed by a suitable instruction execution system. If implemented in hardware, as in another embodiment, it can be implemented using any one or a combination of the following techniques known in the art: discrete logic circuits having logic gates for implementing logical functions on data signals, application-specific integrated circuits (ASICs) having suitable combinational logic gates, programmable gate arrays (FPGAs), field-programmable gate arrays (FPGAs), etc.

[0058] Furthermore, the functional units in the various embodiments of this application can be integrated into a processing module, or each unit can exist physically separately, or two or more units can be integrated into a module. The integrated module can be implemented in hardware or as a software functional module. If the integrated module is implemented as a software functional module and sold or used as an independent product, it can also be stored in a computer-readable storage medium.

[0059] In summary, this application discloses an outdoor survival whistle, comprising a housing 10, a power supply 20, a control board 30, a pressing component 40, a sound component 50, and a light-emitting component 60. The housing 10 contains an installation chamber 11. The power supply 20 and the control board 30 are both located within the installation chamber 11. The power supply 20 is electrically connected to the control board 30, and a step-up transformer 31 is mounted on the control board 30. The pressing component 40 is located within the housing 10 and is electrically connected to the control board 30.
