Description

Technical Field

[0001] This application relates to the field of alarm devices, and more particularly to a personal safety alarm device. Background Technology

[0002] Personal alarms are widely used in the field of personal safety alarms. They typically include a buzzer and a warning light, which provide a dual warning effect by emitting light and sound, making it easy for users to quickly send out an alarm signal when they encounter danger, thereby deterring or even scaring away criminals.

[0003] Existing personal alarms typically use a latch to trigger the alarm. Many latches on the market are made of metal parts. A conductive metal latch is inserted into the socket of the personal alarm to control the circuit of the alarm, thus putting the alarm in standby mode. When the latch is pulled out, the internal circuit of the alarm is disconnected, thereby triggering the circuit program and causing the personal alarm to start and emit an alarm sound and light.

[0004] Regarding the aforementioned technologies, in existing personal alarms, the metal pins are easily affected by environmental humidity and become damp and rusty. The rust layer on the surface not only increases the resistance to plugging and unplugging but also easily affects the electrical connection performance of the circuit, which in turn leads to unstable start-up or shutdown of the personal alarm. This can easily cause the personal alarm to fail to send an alarm signal when the user encounters danger. Summary of the Invention

[0005] To make the activation or deactivation of a personal alarm more stable, this application provides a personal safety alarm.

[0006] The personal safety alarm device provided in this application adopts the following technical solution:

[0007] A personal safety alarm includes a socket, a plug, and an alarm component. The socket has a slot, the plug passes through and engages with the slot, and the alarm component is disposed in the socket and is used to emit an alarm signal.

[0008] The alarm component includes a circuit board, an alarm light, and a buzzer. The circuit board is fixedly installed inside the socket. An alarm button is fixedly connected to the circuit board. When the pin passes through and engages with the slot, the pin presses the alarm button.

[0009] The alarm light is installed in the socket and electrically connected to the circuit board. The alarm light is used to emit a light alarm signal. The buzzer is installed in the socket and electrically connected to the circuit board. The buzzer is used to emit an audible alarm signal.

[0010] Optionally, the buzzer and the circuit board are electrically connected via a power-conducting wire to ensure a stable electrical connection between the buzzer and the circuit board.

[0011] Optionally, the alarm component further includes a battery module disposed inside the socket and electrically connected to the circuit board to power the circuit board.

[0012] Optionally, the socket has a circuit cavity, a battery cavity, and a buzzer cavity, which are arranged sequentially from the direction closest to the plug to the direction furthest from the plug.

[0013] The circuit board is disposed in the circuit cavity, the battery module is disposed in the battery cavity, and the buzzer is disposed in the buzzer cavity.

[0014] Optionally, the socket has a through-hole light hole and multiple connection holes, the light hole is connected to the circuit cavity, and the connection holes are evenly distributed around the axis of the light hole in the circumferential direction;

[0015] The alarm light is fixedly provided with multiple connecting posts. When the alarm light is installed in the socket, the alarm light passes through the light hole, and each of the connecting posts passes through and is fixedly installed in the respective connecting hole.

[0016] Optionally, the socket includes two base parts. One base part is fixedly provided with multiple snap-fit ​​blocks, and the other base part is provided with multiple snap-fit ​​slots. When the two base parts are fixedly connected, each snap-fit ​​block passes through and snaps into each of the snap-fit ​​slots.

[0017] Optionally, the socket further includes a connecting portion, both of the base portions abutting and engaging with the connecting portion to form a socket, and the slot is located in the connecting portion.

[0018] Optionally, the pin is fixedly provided with a plurality of fixing protrusions. When the pin passes through the slot and engages with the slot, each fixing protrusion abuts against the connecting part.

[0019] Optionally, both of the base portions are fixedly provided with fixing posts, and one of the base portions is also fixedly provided with positioning posts. The circuit board has a through positioning hole. When the circuit board is installed in the socket, the fixing posts of the two base portions are respectively abutted and fixed to both sides of the circuit board, and the positioning posts pass through the positioning holes.

[0020] Optionally, the pin has a through hole to facilitate pulling the pin.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] In this application, when the alarm button is pressed, the personal alarm is in standby mode and is not triggered. At this time, neither the alarm light nor the buzzer works. When the alarm is not pressed, the alarm circuit of the circuit board is disconnected, thereby triggering the personal alarm to sound, that is, the alarm light emits a light alarm signal and the buzzer emits an audible alarm signal. Therefore, when a user activates the personal alarm, pulling the latch disengages it from the slot. Once disengaged, the alarm button, no longer pressed, springs back up, causing the circuit board to simultaneously activate the alarm light and buzzer, emitting both a light and sound alarm. To stop the alarm, the latch is reinserted into the slot, pressing the alarm button and stopping the alarm. In summary, controlling the alarm circuit's on / off state by releasing or holding the latch on the alarm button makes the personal alarm less susceptible to environmental humidity and component aging, resulting in more stable activation and deactivation. This addresses the issue in existing personal alarms where the metal latch is easily affected by humidity and rust. Rust not only increases insertion / removal resistance but also affects electrical connections, leading to unstable activation and deactivation, and potentially causing alarm failures when the user encounters danger.

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0033] This application discloses a personal safety alarm device. (Refer to...) Figure 1 , Figure 2 as well as Figure 3 A personal safety alarm includes a socket 1, a pin 2, and an alarm component 3. The socket 1 has a slot 11, through which the pin 2 passes and engages with the slot 11. The alarm component 3 is disposed in the socket 1 and is used to emit an alarm signal. The alarm component 3 includes a circuit board 31, an alarm light 32, and a buzzer 33. The circuit board 31 is fixedly disposed inside the socket 1 and is electrically connected to an alarm button 311. When the pin 2 passes through and engages with the slot 11, the pin 2 presses the alarm button 311. The alarm light 32 is disposed in the socket 1 and electrically connected to the circuit board 31, and is used to emit a light alarm signal. The buzzer 33 is disposed in the socket 1 and electrically connected to the circuit board 31, and is used to emit an audible alarm signal.

[0034] Reference Figure 1 , Figure 2 as well as Figure 3 It should be noted that the circuit board 31 is equipped with an alarm circuit. The alarm button 311 can control the conduction or disconnection of the alarm circuit. When the alarm button 311 is pressed, the alarm button 311 closes the alarm circuit, thus making the alarm circuit in an open circuit state. When the alarm button 311 is not pressed, the alarm button 311 resets and pops up, thus making the alarm circuit in a conduction state.

[0035] Reference Figure 1 , Figure 2 as well as Figure 3In this embodiment, the buzzer 33 and the circuit board 31 can be electrically connected through metal terminals, or through a live wire. Preferably, the buzzer 33 and the circuit board 31 are electrically connected through a live wire, which reduces the resistance between them and makes it less likely to affect the stability of the electrical connection when the buzzer 33 vibrates. This avoids the instability of the electrical connection between the buzzer 33 and the circuit board 31 when they are connected through metal terminals, which would otherwise cause the alarm signal emitted by the buzzer 33 to attenuate due to vibration.

[0036] Reference Figures 2 to 4 In this embodiment, the alarm component 3 further includes a battery module 34, which is disposed inside the socket 1 and electrically connected to the circuit board 31 to supply power to the circuit board 31. Preferably, the battery module 34 is composed of multiple button batteries, thereby making the power supply of the battery module 34 to the circuit board 31 more stable. It should be noted that, in order to accommodate button batteries, the socket 1 has a through-hole partition slot 12, so that when the personal alarm is sold or stopped, a partition card that can disconnect the electrical connection of each button battery can be inserted into the partition slot 12 to stop the battery module 34 from supplying power to the circuit board 31, so that the battery module 34 has sufficient power when the user needs to use the personal alarm.

[0037] Reference Figures 2 to 5 In this embodiment, the socket 1 has a circuit cavity 13, a battery cavity 14, and a buzzer cavity 15. The circuit cavity 13, battery cavity 14, and buzzer cavity 15 are arranged sequentially from the direction closest to the plug 2 to the direction furthest from the plug 2. The circuit board 31 is disposed in the circuit cavity 13, the battery module 34 is disposed in the battery cavity 14, and the buzzer 33 is disposed in the buzzer cavity 15. This makes it difficult for the circuit board 31, the battery module 34, and the buzzer 33 to interfere with each other. It should be understood that although the circuit cavity 13, the battery cavity 14, and the buzzer cavity 15 are provided in the socket 1, the electrical connection between the buzzer 33 and the circuit board 31, as well as the electrical connection between the battery module 34 and the circuit board 31, can still be ensured through the layout of the connecting lines. In a further embodiment, the socket 1 has a through-hole light hole 16 and multiple connection holes 17. The light hole 16 is connected to the circuit cavity 13. The connection holes 17 are evenly distributed around the axis of the light hole 16. The alarm light 32 is fixedly provided with multiple connecting posts 321. When the alarm light 32 is provided in the socket 1, the alarm light 32 passes through the light hole 16, and each connecting post 321 passes through and is fixedly provided in each connection hole 17.

[0038] Reference Figure 2 and Figure 6 In this embodiment, the socket 1 includes two base portions 1a. One base portion 1a is fixedly provided with a plurality of snap-fit ​​blocks 1a1, and the other base portion 1a has a plurality of snap-fit ​​slots 1a2. When the two base portions 1a are fixedly connected, each snap-fit ​​block 1a1 passes through and snaps into each snap-fit ​​slot 1a2. In a further embodiment, the socket 1 also includes a connecting portion 1b. Both base portions 1a abut against the connecting portion 1b to form the socket 1. The slot 11 is located in the connecting portion 1b. It should be understood that the two base portions 1a abut against the connecting portion 1b to form the socket. When the two body parts 1a abut against multiple sides of the connecting part 1b, the position of the connecting part 1b is stable and does not easily change when it abuts against the two body parts 1a. In addition, the design of the connecting part 1b improves the manufacturing precision of the connecting part 1b, thereby improving the fitting precision between the pin 2 and the connecting part 1b. This ensures that when the pin 2 needs to be pulled out, the force required to pull the pin 2 out of the slot 11 is appropriate, so that the pin 2 can be pulled out quickly and that the pin 2 cannot be dislodged from the slot 11 during daily carrying.

[0039] Reference Figure 2 In a further embodiment, the pin 2 is fixedly provided with a plurality of fixing protrusions 21. When the pin 2 passes through the slot 11 and engages with the slot 11, each fixing protrusion 21 abuts against the connecting part 1b. (Refer to...) Figure 6 and Figure 7 In a further embodiment, both body parts 1a are fixedly provided with fixing posts 1a3, and one of the body parts 1a is also fixedly provided with positioning posts 1a4. The circuit board 31 has a through positioning hole 312. When the circuit board 31 is installed in the socket 1, the fixing posts 1a3 of the two body parts 1a are respectively abutted and fixed to both sides of the circuit board 31, and the positioning posts 1a4 are inserted through the positioning hole 312.

[0040] Reference Figure 8 In this embodiment of the application, the pin 2 has a through-hole 22, so that when the user needs to pull out the pin 2, he / she can quickly pull out the pin 2 by inserting his / her finger into the pin hole 22, thus making it simpler and more convenient to pull out the pin 2.

[0041] The implementation principle of a personal safety alarm according to an embodiment of this application is as follows: In this application, when the alarm button 311 is pressed, the personal alarm is in standby mode and is not triggered. At this time, the alarm light 32 and the buzzer 33 are not working. When the alarm is not pressed, the alarm circuit of the circuit board 31 is disconnected, thereby triggering the personal alarm to sound an alarm, that is, the alarm light 32 emits a light alarm signal and the buzzer 33 emits an audible alarm signal. Therefore, when a user activates the personal alarm, pulling the latch 2 disengages it from the slot 11. Once the latch 2 is disengaged, the alarm button 311, no longer pressed by the latch 2, resets and pops back up. This causes the circuit board 31 to simultaneously activate the alarm light 32 and the buzzer 33, emitting both a light and an audible alarm signal. To stop the alarm, the latch 2 is reinserted into the slot 11, pressing the alarm button 311 and stopping the alarm. In summary, by releasing the latch 2… Pressing or holding the alarm button 311 controls the on / off state of the alarm circuit on the circuit board 31, making the personal alarm less susceptible to environmental humidity and component aging issues. This results in a more stable start-up and shutdown of the personal alarm. In existing personal alarms, the metal pin 2 is easily affected by environmental humidity and rusts. The rust layer on its surface not only increases the insertion and removal resistance but also easily affects the electrical connection performance of the circuit, leading to unstable start-up or shutdown of the personal alarm. This can easily cause the alarm to fail to send an alarm signal when the user encounters danger.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
