Description

Technical Field

[0001] The invention relates to the technical field of alarm devices, in particular to a portable multifunctional silent alarm device. Background Art

[0002] Traditionally, when encountering an emergency, victims usually use their mobile phones to call the police, but this method has obvious shortcomings. On the one hand, operating the mobile phone to call the police may not be convenient enough in a tense situation; on the other hand, the sound and action of using the mobile phone to call the police can easily alert criminals, thereby increasing the danger to the victims. Therefore, alarm devices designed specifically for vulnerable groups came into being.

[0003] Traditional alarm devices usually have a one-button alarm function, and the alarm device has structures such as spikes or electrodes for self-defense. When the user takes out the alarm device, he can press the alarm button, and the alarm device can immediately make an alarm noise to scare away the criminals; in addition, the user can attack the perpetrator through the spikes or electrodes on the alarm device, thereby achieving the purpose of protecting his own life safety. However, this type of alarm device has obvious disadvantages. For example, in the wild environment, even if the alarm device makes a noise, it cannot scare away the perpetrator; secondly, although the self-defense structure on the alarm device has a certain attack capability, it also needs to be used by the user, otherwise it is likely to be countered by the perpetrator.

[0004] Existing alarm devices usually also have a positioning function. For example, the Chinese patent with publication number CN220627208U proposes a portable anti-wolf alarm, which specifically includes a handle, a flash light body, electrodes, a positioning device and an audio device. The audio device is used to emit a warning sound, and the positioning device is used to send real-time positioning to the contact person, so that the contact person can find the victim as soon as possible.

[0005] However, although the existing alarm device has a positioning function and can greatly improve the safety of users, it still has certain disadvantages. For example, when the user takes out the alarm device and presses the switch button, it often arouses the vigilance of the perpetrator, which may cause the perpetrator to snatch the alarm device and throw it away. Therefore, once the alarm device is thrown away by the perpetrator, its positioning function for the victim will no longer exist. In view of this, we propose a portable multifunctional silent alarm device to effectively solve the above disadvantages. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 - Figure 8 A portable multifunctional silent alarm device includes a shell 100. The shell 100 is a two-stage structure, with a front end in a disc shape and a rear end in a rectangular parallelepiped shape. The shell 100 is fixed by bolts on an upper and lower half body. A circuit board 200 and a power supply 300 are arranged inside the shell 100. A lighting bulb 400 is arranged at the front end of the shell 100. A central processing unit 201, a recording module 202 and a wireless communication module 203 are arranged on the circuit board 200. The lighting bulb 400, the central processing unit 201, the recording module 202 and the wireless communication module 203 are all electrically connected to the power supply 300. The signal output end of the recording module 202 is connected to the signal input end of the central processing unit 201, and the signal output end of the central processing unit 201 is connected to the wireless communication module 203. Specifically, a power slot (not shown in the figure) for installing a power supply is provided on the back of the shell 100, and a power cover is provided on the outside of the power slot. The power supply adopts a primary battery, has a long standby time, and does not need to be charged. At the same time, a bulb switch 101 for controlling the lighting of the lighting bulb 400 is also provided on one side of the outer surface of the housing 100 so that the user can use it as a flashlight at night.

[0034] Furthermore, a sound receiving cover 102 is fixedly embedded on the front of the housing 100, and the sound receiving cover 102 is located at a position directly facing the recording module 202; an information storage module 204 is also provided on the circuit board 200, such as Figure 2 As shown, the information storage module 204 is electrically connected to the output end of the central processor 201; the circuit board 200 is also provided with a toggle switch 205, which is electrically connected to the central processor 201. Under normal conditions, the toggle switch 205 is in an off state, and the recording module 202 does not work at this time; when the toggle switch 205 is turned on, the central processor 201 receives the switch-on signal at the first time, and starts the recording module 202 to power on, and the recording module 202 sends the collected audio information to the central processor 201, and the central processor 201 stores the audio in the information storage module 204, and at the same time sends the audio signal to the mobile terminal of the emergency contact through the wireless communication module 203.

[0035] It is worth mentioning that the wireless communication module 203 adopts a 4G communication module. At the same time, when the toggle switch 205 is turned on, the central processor 201 sends an alarm message to the mobile phone terminal of the emergency contact through the wireless communication module 203, thereby reminding the emergency contact in the first time.

[0036] More specifically, an ambient light 103 is provided on the front of the housing 100 and outside the sound receiving cover 102. Figure 1 As shown, the atmosphere lamp 103 is electrically connected to the output terminal of the central processor 201; the circuit board 200 is also provided with a vibration motor 206, as shown in FIG. Figure 2 As shown, the vibration motor 206 is electrically connected to the output terminal of the central processor 201. When the toggle switch 205 is turned on, the central processor 201 immediately starts the atmosphere light 103 and the vibration motor 206 to work, specifically, starts the atmosphere light 103 to flash twice, starts the vibration motor 206 to vibrate for several seconds, thereby reminding the user that the alarm is successful.

[0037] Furthermore, a button hole 104 is provided on the side of the housing 100, and a button block 105 is provided at the movable end of the toggle switch 205, and the outer end of the button block 105 passes through the button hole 104 and extends to the outside of the housing 100; a pull-out portion 500 is also provided inside the housing 100, and a locator 501 is provided inside the pull-out portion 500, and one end of the pull-out portion 500 extends outside the housing 100, and the pull-out portion 500 is also detachably connected to the housing 100. The use of an up-and-down sliding switch can largely avoid accidental touches and improve the accuracy of the alarm. In addition, the locator 501 uses a Beidou locator. When the locator 501 is turned on, the emergency contact can view the location of the locator 501 in real time through the terminal device.

[0038] In addition, a pull-out hole is provided at the rear end of the housing 100, and a positioning sleeve 106 is provided on the inner surface of the rear end of the housing 100 and outside the pull-out hole. Figure 6 As shown, the pull-out portion 500 is inserted into the positioning sleeve 106, and the inner surface of the positioning sleeve 106 is provided with a sealing layer 107, and the sealing layer 107 is tightly fitted with the outer surface of the pull-out portion 500. The function of the sealing layer 107 is to improve the stability of the pull-out portion 500 and prevent it from moving back and forth; in addition, the pull-out portion 500 is composed of two halves, the upper and lower halves, and the interior of the pull-out portion 500 also has a button battery 502 for powering the locator 501. Secondly, a connecting hole 503 is provided at the outer end of the pull-out portion 500, and a key ring 505 is connected to the connecting hole 503 through an iron chain 504, so that the user can bind the device to a key chain for easy carrying.

[0039] A positioning portion 600 is fixedly disposed on the circuit board 200. Figure 2As shown, the positioning portion 600 is located at the front side of the pull-out portion 500, and the front and rear ends of the positioning portion 600 are respectively provided with an adjustment hole 601 and a mounting hole 602, wherein the mounting hole 602 is used for the front end of the pull-out portion 500 to be inserted, and the upper and lower surfaces of the positioning portion 600 are both provided with positioning holes 603 that communicate with the adjustment hole 601 and the mounting hole 602. Figure 3 As shown, a cover body 604 is provided in each of the two positioning holes 603, a guide column 605 is provided on the inner surface of the cover body 604, and positioning blocks 606 are also movably provided in the two positioning holes 603, the positioning blocks 606 and the guide columns 605 are slidably matched, and a positioning spring 607 is connected between the positioning blocks 606 and the corresponding cover body 604, and positioning columns 608 are provided on the facing surfaces of the two positioning blocks 606, and a through hole 506 for inserting the positioning columns 608 is provided through the pull-out portion 500. In a natural state, the positioning spring 607 is in a compressed state, and the positioning column 608 is embedded in the through hole 506, so that the position of the pull-out portion 500 is fixed.

[0040] Furthermore, a displacement portion 609 is slidably connected in the adjustment hole 601, a displacement hole 610 is penetrated through the displacement portion 609, a displacement block 611 is slidably connected in the displacement hole 610, and connecting rods 612 are hingedly provided at both upper and lower ends of the displacement block 611, and the ends of the two connecting rods 612 are respectively hinged to the two positioning blocks 606; a guide portion 207 is provided at an edge position of one side of the circuit board 200, and a push rod 208 is slidably connected to the guide portion 207, and both ends of the push rod 208 are fixedly connected to the button block 105 and the displacement portion 609, respectively. When the toggle switch 205 is in the off state, the positioning column 608 is embedded in the through hole 506; when the toggle switch 205 is in the closed state, the positioning column 608 is detached from the through hole 506. When the toggle switch 205 needs to be closed, the user needs to push the button block 105 forward, thereby indirectly driving the displacement portion 609 forward through the push rod 208, so that the positioning column 608 is disengaged from the through hole 506, and the pull-out portion 500 can be pulled out from the inside of the shell 100 by force.

[0041] It is worth mentioning that the on / off positions of the toggle switch 205 have a self-locking function. When the user pushes the button block 105 forward until the toggle switch 205 is closed, the position of the button block 105 can be locked, that is, the thrust of the positioning spring 607 is not sufficient to reset the button block 105.

[0042] On the other hand, a hidden hole 507 is provided on the front end surface of the pull-out portion 500, a through hole 613 is provided between the adjustment hole 601 and the mounting hole 602, the inside of the hidden hole 507 is elastically connected to an insulating block 508 through a spring, and both left and right ends of the insulating block 508 are provided with conductive contacts 509, and both left and right side walls of the inside of the hidden hole 507 are provided with conductive contact sheets 510, the two conductive contacts 509 are respectively connected to the positive and negative electrodes of the button battery 502, and the two conductive contact sheets 510 are respectively connected to the two ends of the positioner 501. The lead wire is connected. When the toggle switch 205 is in the off state, one end of the displacement portion 609 passes through the penetration hole 613 and extends into the hidden hole 507 and abuts against the insulating block 508, and the two conductive contacts 509 and the two conductive contact pieces 510 are not in contact; when the toggle switch 205 is in the closed state, the end of the displacement portion 609 moves out of the hidden hole 507, and under the action of the spring, the insulating block 508 moves forward. At this time, the two conductive contacts 509 respectively abut against the two conductive contact pieces 510, and the positioner 501 is powered on and opened.

[0043] In summary, in the actual application of this embodiment, when the user encounters a criminal following or infringing upon him, the user can take out the device and push the button block 105 forward with the thumb. When the button block 105 is pushed forward, the toggle switch 205 is closed, and the central processor 201 receives the alarm signal, and the central processor 201 immediately starts the recording module 202, the vibration motor 206 and the atmosphere light 103, wherein the vibration of the vibration motor 206 and the flashing of the atmosphere light 103 can remind the user that the alarm is successful, and after the recording module 202 is turned on, the on-site recording can be collected, and the central processor 201 then sends the on-site audio to the emergency contact through the wireless communication module 203, so that the emergency contact can grasp the on-site situation in time.

[0044] Secondly, the CPU 201 also sends an alarm prompt SMS to the emergency contact's mobile phone terminal through the wireless communication module 203, thereby timely reminding the emergency contact. At the same time, when the button block 105 is pushed forward, the locator 501 is also powered on, and the emergency contact can lock the user's location through the signal sent by the locator 501, so as to rush to the scene as soon as possible.

[0045] On the other hand, when the user takes out the alarm device and pushes the button block 105, if the perpetrator is alerted by this action, the perpetrator may snatch the alarm device. At this time, the user can actively hold the housing 100 and pull it out, so that the pull-out portion 500 remains on the keychain. The pull-out portion 500 is small in size and connected to the key ring, so it has strong concealment and is easily overlooked by the perpetrator. Therefore, compared with the existing alarm device, the present invention has stronger concealment, which is conducive to the emergency contact person to lock the user's location in real time.
