Description

Technical Field

[0001] The present invention relates to the technical field of traffic safety equipment, and specifically relates to an alarm device for a vehicle that is triggered by a specific audio for alarm. Background Art

[0002] In recent years, with the growth of the national economy, cars have become more and more popular. Cars have now become an important means of transportation in people's daily lives. While bringing convenience to our lives, they also pose a threat to our personal and property safety. As the number of vehicles on the road surface increases, the incidence of traffic accidents also increases. Every year, a huge number of people lose their lives due to car accidents in our country, bringing huge economic and mental losses to the country and the people. In many traffic safety accidents, the driver enters a fainting state after a violent car impact, resulting in the delay of the best time to call for help and ultimately causing an irreparable situation.

[0003] According to an alarm column triggered by a specific audio provided by Chinese Patent No. CN201710027836.4, this document includes an alarm column and an automatic alarm device installed on the alarm column. The automatic alarm device includes an audio acquisition module for collecting audio signals, a control module for processing audio data, and a networking module for transmitting alarm information to the alarm receiving center. The networking module is connected to a telephone network or the Internet. The control module includes an audio storage module and an audio recognition module. The audio acquisition module is connected to the input end of the control module through an audio acquisition circuit, and the networking module is connected to the output end of the control module.

[0004] However, if the alarm column triggered by a specific audio proposed in this document is installed in a vehicle, when a car accident occurs, if the impact generated by the car accident is relatively violent, it is easy to cause the internal device to malfunction under the impact of various sundries or fragments that take off during the impact, resulting in the delay of the alarm time and inconvenient use. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the present invention provides an alarm device for a vehicle that is triggered by a specific audio for alarm, and solves the problems raised in the above background art.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the present invention is realized by the following technical solutions: An alarm device for triggering an alarm with specific audio for an automobile, comprising a housing, a bottom plate fixedly connected inside the housing, an automatic alarm device provided on the back surface of the bottom plate, protection mechanisms symmetrically arranged on the left and right sides of the housing, and a side collision trigger mechanism provided on the bottom plate. When the automobile is violently impacted on the left or right side, the side collision trigger mechanism will trigger the corresponding protection mechanism.

[0009] Preferably, the automatic alarm device includes a sound pickup module, an audio recognition module, and a networking module. The sound pickup module, the audio recognition module, and the networking module are connected in sequence. The sound pickup module collects audio signals, the audio recognition module analyzes, processes, and recognizes the audio signals collected by the sound pickup module, and compares them with the audio sample feature library stored in the audio recognition module. The networking module is connected to the telephone network or the Internet to transmit alarm information to the alarm center.

[0010] Preferably, the protection mechanism includes a housing, a top cover, a safety airbag, an inflation device, and two contact pieces. The housing is fixedly connected to the outside of the housing. The inflation device is fixedly connected inside the housing. A safety airbag is fixedly connected to one side of the inflation device. The housing is connected with a top cover. One end of the inflation device is fixedly connected with two contact pieces, and the two contact pieces extend into the housing. When the two contact pieces are connected, the inflation device forms a circuit so that the inflation device inflates the safety airbag, and the safety airbag expands to push the top cover out of the housing.

[0011] Preferably, the side impact trigger mechanism includes a turntable, an eccentric weight, a first permanent magnet, an arc seat, a second permanent magnet, a first installation groove, and an iron sheet. The turntable is rotatably connected to the bottom plate. An eccentric weight is fixedly connected to the top end of the turntable. Iron sheets are fixedly connected to both sides of the eccentric weight. A first permanent magnet is fixedly connected to the bottom end of the turntable. An arc seat is arranged below the turntable. The arc seat is fixedly connected to the housing. A first installation groove is formed in the middle of the top of the arc seat. A second permanent magnet is slidably fitted in the first installation groove. A non-slip layer is fixedly connected to the top of the second permanent magnet. Under normal conditions, the eccentric weight at the top of the turntable is at the highest position. The first permanent magnet at the bottom of the turntable corresponds to the second permanent magnet in the first installation groove, and the first permanent magnet and the second permanent magnet are mutually attracting magnets. The second permanent magnet rises under the action of the magnetic force, so that the non-slip layer of the second permanent magnet abuts against the turntable. Under the action of the frictional force, the turntable keeps the eccentric weight at the highest position. When the left side of the vehicle is subjected to a violent impact of sufficient intensity, the vehicle body will instantaneously move to the right due to the left impact. At this time, the eccentric weight as an eccentric counterweight drives the turntable to rotate counterclockwise under the action of the inertial force, and then instantaneously overcomes the static friction between the first permanent magnet and the second permanent magnet. The turntable rotates counterclockwise until the eccentric weight contacts the contact piece of the left protection mechanism. Under the action of the iron sheet, the two contact pieces of the left protection mechanism and the iron sheet form a circuit, so as to trigger the airbag in the left protection mechanism, and the airbag pops up to protect the left side of the device.

[0012] Preferably, second installation grooves are formed in the arc seat on both sides of the first installation groove. A third permanent magnet is slidably fitted in the second installation groove. A non-slip layer is fixedly connected to the top end of the third permanent magnet. The first permanent magnet and the third permanent magnet are mutually attracting magnets. A buzzer and a single-chip microcomputer are arranged on the bottom plate. A fourth permanent magnet is fixedly connected to the back of the turntable and below the eccentric weight. A straight cylinder is fixedly connected to the back of the bottom plate. A fifth permanent magnet is slidably fitted in the straight cylinder. The fifth permanent magnet and the fourth permanent magnet are mutually repulsive magnets. One end of the fifth permanent magnet is fixedly connected to a spring. The other end of the spring is fixedly connected to the bottom end of the straight cylinder. A button sensor is fixedly connected to the bottom end of the straight cylinder. When the fourth permanent magnet corresponds to the fifth permanent magnet in the straight cylinder, under the action of the repulsive magnetic force, the fifth permanent magnet moves towards the bottom end of the straight cylinder until the button sensor is pressed. When the button sensor is pressed, the button sensor sends a signal to the single-chip microcomputer, and the single-chip microcomputer controls the buzzer to generate an alarm sound. When the button sensor pops up, the buzzer stops the alarm sound.

[0013] Preferably, four straight cylinders are provided.

[0014] Preferably, it further includes a mounting base, a reinforcing plate, a first connecting plate, and a second connecting plate. The mounting base is disposed above the outer shell. The bottom of the mounting base is fixedly connected to the first connecting plate. The top of the outer shell is fixedly connected to the second connecting plate. The reinforcing plate is connected to the first connecting plate and the second connecting plate by bolts.

[0015] Preferably, the protection mechanism is disposed on both sides of the bottom of the outer shell.

[0016] (III) Beneficial effects

[0017] The present invention provides an alarm device for specific audio-triggered alarm in automobiles, which has the following beneficial effects:

[0018] 1. For the alarm device for specific audio-triggered alarm in automobiles, through the setting of the automatic alarm device, when a car accident occurs, the sound pickup module collects the impact audio at the scene. The audio recognition module analyzes, processes, and recognizes the audio signal collected by the sound pickup module, and compares it with the audio sample feature library stored in the audio recognition module. The networking module is connected to the telephone network or the Internet to transmit the alarm information to the alarm center, so as to be able to alarm in the first time of the accident and ensure the rescue efficiency.

[0019] 2. For the alarm device for specific audio-triggered alarm in automobiles, through the setting of the side impact trigger mechanism, when the left side of the car is subjected to a violent impact of sufficient intensity, the vehicle body will instantaneously displace to the right due to the left impact. At this time, the eccentric weight increase block as the eccentric counterweight drives the turntable to rotate counterclockwise under the action of inertia force, and then instantaneously overcomes the static friction between the first permanent magnet and the second permanent magnet. The turntable rotates counterclockwise until the eccentric weight increase block contacts the contact piece of the left protection mechanism. Under the action of the iron sheet, the two contact pieces of the left protection mechanism and the iron sheet form a circuit, so as to trigger the airbag in the left protection mechanism. The airbag pops out to protect the left side of the device, thereby preventing the device from being damaged by the fragments and some sundries flying out during the impact, and ensuring that the alarm can be given in time during the accident.

[0020] 3. The alarm device for a car that is triggered by a specific audio. Through the settings of the second installation groove and the third permanent magnet, when a collision occurs, if the accident is relatively minor and the impact force is relatively weak, when the turntable overcomes the static friction of the first permanent magnet and the second permanent magnet under the action of the impact force, when the first permanent magnet passes through the second installation groove, under the action of magnetic suction, the third permanent magnet moves upward and adsorbs with the first permanent magnet. If the subsequent force of the turntable is insufficient, it cannot overcome the static friction between the first permanent magnet and the third permanent magnet, and thus will stop at the third permanent magnet. At this time, the fourth permanent magnet on the turntable just corresponds to the fifth permanent magnet in the straight cylinder. Under the repulsive magnetic force, the fifth permanent magnet moves towards the bottom end of the straight cylinder until the button sensor is pressed. And when the button sensor is pressed, the button sensor sends a signal to the single-chip microcomputer, and the single-chip microcomputer controls the buzzer to generate an alarm sound. If the impact force is very large, resulting in sufficient subsequent force of the turntable, when the first permanent magnet of the turntable passes through the second installation groove, it overcomes the static friction between the first permanent magnet and the third permanent magnet and continues to rotate until the iron sheet fits with the contact piece of the protection mechanism, triggering the protection mechanism, causing the airbag to pop out. At the same time, the fourth permanent magnet on the turntable just corresponds to the fifth permanent magnet in the straight cylinder. Under the repulsive magnetic force, the fifth permanent magnet moves towards the bottom end of the straight cylinder until the button sensor is pressed. And when the button sensor is pressed, the button sensor sends a signal to the single-chip microcomputer, and the single-chip microcomputer controls the buzzer to generate an alarm sound. Thus, it can judge whether the airbag of the protection mechanism is needed according to the impact degree of the accident, so as to prevent waste caused by the airbag popping out in some minor impact accidents.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] The embodiment of the present invention provides an alarm device for triggering an alarm with a specific audio for an automobile, as Figure 1-8 shown, including a housing 1, a bottom plate 10 is fixedly connected inside the housing 1, an automatic alarm device 14 is provided on the back of the bottom plate 10, protection mechanisms are symmetrically arranged on the left and right sides of the housing 1, and a side collision triggering mechanism is arranged on the bottom plate 10. When the automobile is violently impacted on the left or right side, the side collision triggering mechanism will trigger the corresponding protection mechanism.

[0032] The automatic alarm device 14 includes a sound pickup module, an audio recognition module and a networking module. The sound pickup module, the audio recognition module and the networking module are connected in sequence. The sound pickup module collects audio signals, the audio recognition module analyzes, processes and recognizes the audio signals collected by the sound pickup module, and compares them with the audio sample feature library stored in the audio recognition module. The networking module is connected to the telephone network or the Internet and transmits alarm information to the alarm center.

[0033] Through the setting of the automatic alarm device 14, when a car accident occurs, the sound pickup module collects the impact audio at the scene, the audio recognition module analyzes, processes and recognizes the audio signals collected by the sound pickup module, and compares them with the audio sample feature library stored in the audio recognition module. The networking module is connected to the telephone network or the Internet and transmits alarm information to the alarm center, so that an alarm can be made in the first time of the accident and the rescue efficiency can be guaranteed.

[0034] The protection mechanism includes a housing 4, a top cover 17, an airbag 19, an inflation device 20, and two contact pieces 7. The housing 4 is fixedly connected to the outside of the outer shell 1. An inflation device 20 is fixedly connected inside the housing 4. One side of the inflation device 20 is fixedly connected to an airbag 19. A top cover 17 is connected to the housing 4. One end of the inflation device 20 is fixedly connected to two contact pieces 7, and the two contact pieces 7 extend into the inner part of the outer shell 1. When the two contact pieces 7 are connected, the inflation device 20 forms a circuit so that the inflation device 20 inflates the airbag 19, and the inflated airbag 19 pushes the top cover 17 out of the housing 4.

[0035] The side impact trigger mechanism includes a turntable 9, an eccentric weight 8, a first permanent magnet 11, an arc seat 12, a second permanent magnet 22, a first installation groove 21, and an iron sheet 13. The turntable 9 is rotatably connected to the bottom plate 10. The top end of the turntable 9 is fixedly connected to an eccentric weight 8. Iron sheets 13 are fixedly connected to both sides of the eccentric weight 8. The bottom end of the turntable 9 is fixedly connected to a first permanent magnet 11. An arc seat 12 is arranged below the turntable 9. The arc seat 12 is fixedly connected to the outer shell 1. A first installation groove 21 is opened in the middle of the top of the arc seat 12. A second permanent magnet 22 is slidably fitted in the first installation groove 21. A non-slip layer is fixedly connected to the top of the second permanent magnet 22. Under normal conditions, the eccentric weight 8 at the top of the turntable 9 is at the highest position. The first permanent magnet 11 at the bottom of the turntable 9 corresponds to the second permanent magnet 22 in the first installation groove 21, and the first permanent magnet 11 and the second permanent magnet 22 are mutually attracting magnets. The second permanent magnet 22 rises under the action of magnetic force so that the non-slip layer of the second permanent magnet 22 abuts against the turntable 9. Under the action of friction, the turntable 9 maintains the state where the eccentric weight 8 is at the highest position. When the left side of the car is subjected to a violent impact of sufficient intensity, the vehicle body will instantaneously shift to the right due to the left impact. At this time, the eccentric weight 8, which is an eccentric counterweight, drives the turntable 9 to rotate counterclockwise under the action of inertia force, and then instantaneously overcomes the static friction between the first permanent magnet 11 and the second permanent magnet 22. The turntable 9 rotates counterclockwise until the eccentric weight 8 contacts the contact piece 7 of the left protection mechanism. Under the action of the iron sheet 13, the two contact pieces 7 of the left protection mechanism and the iron sheet 13 form a circuit, so as to trigger the airbag 19 in the left protection mechanism, and the airbag 19 pops out to protect the left side of the device.

[0036] Through the setting of the side impact trigger mechanism, when the left side of the car is subjected to a violent impact of sufficient intensity, the vehicle body will instantaneously displace to the right due to the left side impact. At this time, the eccentric weight increasing block 8 acting as an eccentric counterweight drives the turntable 9 to rotate counterclockwise under the action of inertia force, and then instantaneously overcomes the static friction between the first permanent magnet 11 and the second permanent magnet 22. The turntable 9 rotates counterclockwise until the eccentric weight increasing block 8 contacts the contact piece 7 of the left protection mechanism. Under the action of the iron sheet 13, the two contact pieces 7 of the left protection mechanism and the iron sheet 13 form a circuit, triggering the airbag 19 in the left protection mechanism. The airbag 19 pops out to protect the left side of the device, thereby preventing failures caused by the impact of fragments and some sundries flying out during the impact, and ensuring that an alarm can be given in time during an accident.

[0037] When the right side of the car is subjected to a violent impact of sufficient intensity, the vehicle body will instantaneously displace to the left due to the right side impact. At this time, the eccentric weight increasing block 8 acting as an eccentric counterweight drives the turntable 9 to rotate clockwise under the action of inertia force, and then instantaneously overcomes the static friction between the first permanent magnet 11 and the second permanent magnet 22. The turntable 9 rotates clockwise until the eccentric weight increasing block 8 contacts the contact piece 7 of the right protection mechanism. Under the action of the iron sheet 13, the two contact pieces 7 of the right protection mechanism and the iron sheet 13 form a circuit, triggering the airbag 19 in the right protection mechanism. The airbag 19 pops out to protect the right side of the device.

[0038] Second installation grooves 23 are formed on both sides of the first installation groove 21 on the arc-shaped seat 12. A third permanent magnet 24 is slidably fitted in the second installation groove 23. An anti-slip layer is fixedly connected to the top end of the third permanent magnet 24. The first permanent magnet 11 and the third permanent magnet 24 are mutually attracting magnets. A buzzer 16 and a single-chip microcomputer 15 are arranged on the bottom plate 10. A fourth permanent magnet 18 is fixedly connected to the back surface of the turntable 9 and below the eccentric weight increasing block 8. A straight cylinder 25 is fixedly connected to the back surface of the bottom plate 10. A fifth permanent magnet 28 is slidably fitted in the straight cylinder 25. The fifth permanent magnet 28 and the fourth permanent magnet 18 are mutually repulsive magnets. One end of the fifth permanent magnet 28 is fixedly connected to a spring 27. The other end of the spring 27 is fixedly connected to the bottom end of the straight cylinder 25. A button sensor 26 is fixedly connected to the bottom end of the straight cylinder 25. And when the fourth permanent magnet 18 corresponds to the fifth permanent magnet 28 in the straight cylinder 25, under the action of the repulsive magnetic force, the fifth permanent magnet 28 moves towards the bottom end of the straight cylinder 25 until the button sensor 26 is pressed. And when the button sensor 26 is pressed, the button sensor 26 sends a signal to the single-chip microcomputer 15, and the single-chip microcomputer 15 controls the buzzer 16 to generate an alarm sound. When the button sensor 26 pops up, the buzzer 16 stops the alarm sound.

[0039] Through the settings of the second installation groove 23 and the third permanent magnet 24, when a collision occurs, if the accident is relatively minor, the impact force is relatively slight. When the turntable 9 overcomes the static friction between the first permanent magnet 11 and the second permanent magnet 22 under the action of the impact force, when the first permanent magnet 11 passes through the second installation groove 23, under the action of magnetic suction, the third permanent magnet 24 moves upward and adsorbs with the first permanent magnet 11. If the subsequent force of the turntable 9 is insufficient, it cannot overcome the static friction between the first permanent magnet 11 and the third permanent magnet 24, and thus will stop at the third permanent magnet 24. At this time, the fourth permanent magnet 18 on the turntable 9 just corresponds to the fifth permanent magnet 28 in the straight cylinder 25. Under the repulsive magnetic force, the fifth permanent magnet 28 moves towards the bottom end of the straight cylinder 25 until the button sensor 26 is pressed. And when the button sensor 26 is pressed, the button sensor 26 sends a signal to the single-chip microcomputer 15, and the single-chip microcomputer 15 controls the buzzer 16 to generate an alarm sound. If the impact force is very large, resulting in sufficient subsequent force of the turntable 9, when the first permanent magnet 11 of the turntable 9 passes through the second installation groove 23, it overcomes the static friction between the first permanent magnet 11 and the third permanent magnet 24 and continues to rotate until the iron sheet 13 fits with the contact piece 7 of the protection mechanism, triggering the protection mechanism, causing the airbag 19 to pop out. At the same time, the fourth permanent magnet 18 on the turntable 9 just corresponds to the fifth permanent magnet 28 in the straight cylinder 25. Under the repulsive magnetic force, the fifth permanent magnet 28 moves towards the bottom end of the straight cylinder 25 until the button sensor 26 is pressed. And when the button sensor 26 is pressed, the button sensor 26 sends a signal to the single-chip microcomputer 15, and the single-chip microcomputer 15 controls the buzzer 16 to generate an alarm sound. Thus, it can be judged whether the airbag 19 of the protection mechanism is needed for protection according to the impact degree of the accident, thereby preventing waste caused by the pop-up of the airbag 19 in some minor impact accidents.

[0040] Four straight cylinders 25 are provided.

[0041] It further includes a mounting seat 2, a reinforcing plate 3, a first connecting plate 5, and a second connecting plate 6. The mounting seat 2 is arranged above the housing 1.

The reinforcing plate 3 is connected to the first connecting plate 5 and the second connecting plate 6 by bolts.

[0042] When the mounting seat 2 is installed, it is fixedly connected to the top of the vehicle, so that it can be conveniently installed in the vehicle.

[0043] The protection mechanism is arranged on both sides of the bottom of the housing 1.

[0044] Working principle: Through the setting of the automatic alarm device 14, when a car accident occurs, the sound pickup module collects the impact audio at the scene. The audio recognition module analyzes, processes, and recognizes the audio signal collected by the sound pickup module, and compares it with the audio sample feature library stored in the audio recognition module. The networking module is connected to the telephone network or the Internet and transmits the alarm information to the alarm center, so that an alarm can be sent in the first moment of the accident, ensuring the rescue efficiency.
