[0003] However, most of the existing recorders are not equipped with anti-fall structures. Since most recorders are worn on the body and used in various occasions, the recorders are often dropped. After falling, they are easily hit and bumped, causing damage to the camera. The repair cost of a damaged recorder is high, which affects its use and makes it impossible to continue to use it, affecting the evidence collection work. The anti-fall structure of the existing recorders with anti-fall structures is relatively simple, and most of them are set on the outside of the recorder, causing the recorder to be too bulky, affecting its use.

[0014] Preferably, the number of the mounting plates is four.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects:
[0016] In the above scheme, a protection unit is set up. When the recorder falls accidentally, the speed sensor in the anti-fall control system senses that the falling speed of the recorder reaches a certain value, and then sends an electrical signal to the protection unit through the anti-fall control system to power on the protection unit. The speed sensor is a prior art and will not be described in detail. The recorder is fully protected by the protection unit to prevent the camera part and the recorder casing from being damaged, thereby realizing the function of automatic protection. The problem of damage to the existing recorder due to accidental falling is reduced, which makes it easier for the recorder to continue working and facilitates the subsequent evidence collection work of the staff.
[0017] By setting a coil and an electric push rod, when the recorder falls and the speed sensor senses that the speed has reached a certain value, the speed sensor sends an electrical signal, so that the coil and the electric push rod are energized, and the coil generates a magnetic force when it is energized. Under the action of the magnetic block, the coil is driven to move, and the movement of the coil drives the second connecting shaft to move, and then drives the limiting bead to move. At the same time, the movement of the second connecting shaft drives the second compression spring to compress. As the limiting bead moves, the limiting bead moves and separates from the exhaust hole, so that the second airbag is connected to the first airbag. The second airbag is a high-elastic structure. Since the second airbag is connected to the first airbag, the high-elastic second airbag filled with gas inflates the first airbag to expand the first airbag. After the first airbag is inflated, the coil is de-energized, and under the action of the second compression spring, the limiting bead is driven to block the exhaust hole. During the expansion of the first airbag, the electric push rod is energized, so that the electric push rod contracts, and then drives the first connecting rod to move, and drives the limiting block to move through the first connecting rod, so that the limiting block is expanded, and the first airbag is automatically inflated and expanded. The opening and limiting blocks are moved to open, so that the recorder is protected by the first airbag and the limiting blocks. In the process of the recorder falling, when the four corners of the recorder touch the ground first, the first airbag contacts the ground first. When the falling speed is large, the limiting blocks play a further buffering role to prevent the first airbag from being damaged by a large impact force. When the limiting blocks are impacted, further buffering is achieved through the first compression spring to prevent the recorder from being damaged by excessive impact force. When the first airbag is subjected to a large impact force, the first airbag pushes the limiting beads to move, so that the limiting beads are separated from the exhaust hole, so that a certain amount of gas flows into the second airbag. After the impact force is reduced, the limiting beads are driven to move by the second compression spring, so that the limiting beads block the exhaust hole. As the gas in the first airbag decreases, the first airbag can be prevented from being damaged by a large impact force, thereby improving the service life of the first airbag. As the gas in the first airbag decreases, the elastic force of the first airbag decreases, so as to prevent the first airbag from rebounding, thereby solving the problem of secondary damage to the recorder caused by rebound.
[0018] By setting an electric push rod and an exhaust sleeve, when the recorder falls and the protection unit needs to be folded up, the electric push rod is started by the control button, and the second connecting rod is driven to move by the electric push rod, and the first connecting rod and the first connecting shaft are driven to move at the same time by the second connecting rod, and the limit block is driven to reset by the first connecting rod, and the piston is driven to move by the first connecting shaft. With the movement, the first rotating plate in the air outlet is driven to rotate and open, and the first airbag is evacuated by the piston, so that the gas in the first airbag is discharged, and the first airbag is attached to the first connecting rod. With the reset of the limit block, the first airbag is stored. At the position between the limit block and the mounting plate, until the limit block is completely moved into the through hole, the protective unit is reset, and then the first connecting shaft is driven by the electric push rod to move in the opposite direction. Under the action of the first reset spring, the first rotating plate is driven to rotate and close. At the same time, the gas in the vacuum sleeve pushes the second rotating plate to rotate and open, and the gas is filled into the second airbag for the next anti-fall use. The first airbag is driven by the piston to flow into the second airbag, thereby realizing the purpose of automatic storage and repeated use. In addition, by arranging the protective unit inside the back cover, the problem of the recorder being too bloated and inconvenient to use is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 2-7 As shown, the protection unit 3 includes a mounting plate 4, which is mounted on the inside of the back cover 2. There are four mounting plates 4, a first connecting rod 5 is inserted on the mounting plate 4, a first through hole is opened on the back cover 2, one end of the first connecting rod 5 is fixedly connected to the limiting block 6 corresponding to the inside of the first through hole, a first airbag 7 is sleeved on the first connecting rod 5, the first airbag 7 is arranged at a position between the mounting plate 4 and the limiting block 6, and the opening of the first airbag 7 is fixedly connected to the mounting plate 4, an electric push rod 14 is installed on the mounting plate 4, the output end of the electric push rod 14 is fixedly connected to the second connecting rod 15, and one end of the first connecting rod 5 is fixedly connected to the second connecting rod 15, a connecting pipe 16 is fixedly connected to the mounting plate 4, and one end of the connecting pipe 16 passes through the mounting plate 4 and is connected to the opening of the first airbag 7, a second airbag 17 is arranged inside the back cover 2, the other end of the connecting pipe 16 is fixedly connected to the second airbag 17, and the second airbag 17 is connected to the The connecting pipe 16 is connected to the first airbag 7, and the second airbag 17 is connected to the exhaust sleeve 9 through the second through hole. Two second mounting frames 18 are arranged inside the connecting pipe 16, and two magnetic blocks 19 are arranged between the two second mounting frames 18. A third mounting frame 20 is arranged inside the connecting pipe 16, and a second connecting shaft 21 is slidably connected to the third mounting frame 20. One end of the second connecting shaft 21 is fixedly connected to a coil 22, and the coil 22 is inserted at a position between the two magnetic blocks 19. The other end of the second connecting shaft 21 is fixedly connected to a limiting bead 23. A second compression spring 24 is sleeved on the second connecting shaft 21, and one end of the second compression spring 24 is fixedly connected to the third mounting frame 20, and the other end of the second compression spring 24 is fixedly connected to the limiting bead 23. A limiting plate 25 is arranged on one side of the connecting pipe 16 corresponding to the limiting bead 23, and an exhaust hole 26 is opened on the limiting plate 25, and the limiting bead 23 is adapted to the exhaust hole 26.
[0038] When the recorder falls and the speed sensor senses that the speed reaches a certain value, the speed sensor sends an electrical signal to energize the coil 22 and the electric push rod 14. The coil 22 generates magnetic force, and under the action of the magnetic block 19, the coil 22 is driven to move. The movement of the coil 22 drives the second connecting shaft 21 to move, and then drives the limiting bead 23 to move. At the same time, the movement of the second connecting shaft 21 drives the second compression spring 24 to be compressed. As the limiting bead 23 moves, the limiting bead 23 moves and separates from the exhaust hole 26, so that the second airbag 17 is connected to the first airbag 7. The second airbag 17 is a highly elastic structure. Since the second airbag 17 is connected to the first airbag 7, the highly elastic second airbag 17 filled with gas inflates the first airbag 7 to expand the first airbag 7. After the first airbag 7 is inflated, the coil 22 is powered off. Under the action of the second compression spring 24, the limiting bead 23 is driven to block the exhaust hole 26. During the expansion of the first airbag 7, the electric push rod 14 is energized to cause the electric push rod 14 to contract, thereby driving the first connecting rod 5 to move, and driving the limiting block 6 to move through the first connecting rod 5, so that the limiting block 6 is expanded, and the first airbag 7 is opened. 7 is automatically inflated and expanded and the limit block 6 is moved and expanded, so that the recorder is protected by the first airbag 7 and the limit block 6. In the process of the recorder falling, when the four corners of the recorder touch the ground first, the first airbag 7 contacts the ground first. When the falling speed is large, the limit block 6 plays a further buffering role to prevent the first airbag 7 from being damaged by a large impact force. When the limit block 6 is impacted, further buffering is achieved through the first compression spring 13 to prevent the recorder from being damaged by excessive impact force. When the first airbag 7 is subjected to a large impact force, the first airbag 7 pushes The limiting bead 23 moves, so that the limiting bead 23 is separated from the exhaust hole 26, allowing a certain amount of gas to flow into the second airbag 17. After the impact force is reduced, the limiting bead 23 is driven to move by the second compression spring 24, so that the limiting bead 23 blocks the exhaust hole 26. As the gas in the first airbag 7 decreases, the first airbag 7 can be prevented from being damaged by a large impact force, thereby increasing the service life of the first airbag 7. As the gas in the first airbag 7 decreases, the elastic force of the first airbag 7 decreases, preventing the first airbag 7 from rebounding, thereby solving the problem of secondary damage to the recorder due to rebound.
[0039] like Figure 2-6As shown, an air outlet 8 is provided on the mounting plate 4 at a position corresponding to the opening of the first airbag 7, a first rotating plate is rotatably connected to one side of the mounting plate 4 corresponding to the air outlet 8, and a first return spring is provided at the position where the mounting plate 4 and the first rotating plate are rotatably connected, a suction sleeve 9 is fixedly connected to one side of the mounting plate 4 corresponding to the air outlet 8, one end of the suction sleeve 9 is communicated with the air outlet 8, a second through hole is provided on one side of the suction sleeve 9, a piston 10 is slidably connected to the inside of the suction sleeve 9, a first connecting shaft 11 is fixedly connected to the piston 10, one end of the first connecting shaft 11 is fixedly connected to the second connecting rod 15, and the first A first compression spring 13 is sleeved on the connecting rod 5, a first mounting bracket 12 is fixedly connected to the mounting plate 4, and one end of the first connecting rod 5 is inserted into the first mounting bracket 12, one end of the first compression spring 13 is fixedly connected to the first connecting rod 5, and the other end of the first compression spring 13 is fixedly connected to the first mounting bracket 12, a second rotating plate is rotatably connected at a position corresponding to the second through hole on the exhaust sleeve 9, and a second return spring is arranged at a position where the second rotating plate is rotatably connected to the exhaust sleeve 9, a control button is arranged on the top of the front cover 1, and the speed sensor is electrically connected to the control button, the electric push rod 14 and the coil 22 respectively.
[0040] After the recorder falls, when the protection unit 3 needs to be folded up, the electric push rod 14 is started by the control button, and the second connecting rod 15 is driven to move by the electric push rod 14, and the first connecting rod 5 and the first connecting shaft 11 are driven to move by the second connecting rod 15 at the same time, and the limit block 6 is reset by the first connecting rod 5, and the piston 10 is driven to move by the first connecting shaft 11. With the movement of the piston 10, the first rotating plate in the air outlet 8 is driven to rotate and open, and the first airbag 7 is evacuated by the piston 10, so that the gas in the first airbag 7 is discharged, and the first airbag 7 is attached to the first connecting rod 5. With the reset of the limit block 6, the first airbag 7 is stored. At the position between the limit block 6 and the mounting plate 4, until the limit block 6 is completely moved into the through hole, the protection unit 3 is reset, and then the first connecting shaft 11 is driven by the electric push rod 14 to move in the opposite direction. Under the action of the first reset spring, the first rotating plate is driven to rotate and close. At the same time, the gas in the vacuum sleeve 9 pushes the second rotating plate to rotate and open, and the gas is filled into the second airbag 17 for the next anti-fall use. The first airbag 7 is driven by the piston 10 to flow into the second airbag 17, so as to achieve the purpose of automatic storage and repeated use. In addition, by arranging the protection unit 3 inside the back cover 2, the problem of the recorder being too bloated and inconvenient to use is reduced.
[0041] The technical solution provided by the present invention is to set a protection unit. When the recorder falls accidentally, the speed sensor in the anti-fall control system senses that the falling speed of the recorder reaches a certain value, and then sends an electrical signal to the protection unit through the anti-fall control system to power on the protection unit. The speed sensor is a prior art and will not be described in detail. The recorder is fully protected by the protection unit to prevent the camera part and the recorder casing from being damaged, thereby realizing the function of automatic protection, reducing the problem of damage to the existing recorder due to accidental falling, making it easier for the recorder to continue working and facilitating the subsequent evidence collection work of the staff.
[0042] By setting a coil and an electric push rod, when the recorder falls and the speed sensor senses that the speed has reached a certain value, the speed sensor sends an electrical signal, so that the coil and the electric push rod are energized, and the coil generates a magnetic force when it is energized. Under the action of the magnetic block, the coil is driven to move, and the movement of the coil drives the second connecting shaft to move, and then drives the limiting bead to move. At the same time, the movement of the second connecting shaft drives the second compression spring to compress. As the limiting bead moves, the limiting bead moves and separates from the exhaust hole, so that the second airbag is connected to the first airbag. The second airbag is a high-elastic structure. Since the second airbag is connected to the first airbag, the high-elastic second airbag filled with gas inflates the first airbag to expand the first airbag. After the first airbag is inflated, the coil is de-energized, and under the action of the second compression spring, the limiting bead is driven to block the exhaust hole. During the expansion of the first airbag, the electric push rod is energized, so that the electric push rod contracts, and then drives the first connecting rod to move, and drives the limiting block to move through the first connecting rod, so that the limiting block is expanded, and the first airbag is automatically inflated. The expansion and limit block move to expand, so that the recorder is protected by the first airbag and the limit block. During the recorder falling process, when the four corners of the recorder touch the ground first, the first airbag contacts the ground first. When the falling speed is high, the limit block plays a further buffering role to prevent the first airbag from being damaged by a large impact force. When the limit block is impacted, further buffering is achieved through the first compression spring to prevent the recorder from being damaged by excessive impact force. When the first airbag is subjected to a large impact force, the first airbag pushes the limit bead to move, so that the limit bead is separated from the exhaust hole, so that a certain amount of gas flows into the second airbag. After the impact force is reduced, the limit bead is driven to move by the second compression spring, so that the limit bead blocks the exhaust hole. As the gas in the first airbag decreases, the first airbag can be prevented from being damaged by a large impact force, thereby increasing the service life of the first airbag. As the gas in the first airbag decreases, the elastic force of the first airbag decreases to prevent the first airbag from rebounding, thereby solving the problem of secondary damage to the recorder caused by rebound.
[0043] By setting an electric push rod and an air extraction sleeve, when the recorder falls and the protection unit needs to be folded up, the electric push rod is started by the control button, and the second connecting rod is driven to move by the electric push rod, and the first connecting rod and the first connecting shaft are driven to move at the same time by the second connecting rod, and the limit block is reset by the first connecting rod, and the piston is driven to move by the first connecting shaft. With the movement of the piston, the first rotating plate in the air outlet is driven to rotate and open, and the first airbag is evacuated by the piston, so that the gas in the first airbag is discharged, and the first airbag is attached to the first connecting rod. With the reset of the limit block, the first airbag is folded. The protective unit is inserted between the limit block and the mounting plate until the limit block is completely moved into the through hole to realize the reset action of the protective unit, and then the first connecting shaft is driven to move in the opposite direction by the electric push rod, and the first rotating plate is driven to rotate and close under the action of the first reset spring. At the same time, the gas in the vacuum sleeve pushes the second rotating plate to rotate and open, and the gas is filled into the second airbag for the next anti-fall use. The first airbag is driven by the piston to flow into the second airbag, so as to realize the purpose of automatic storage and repeated use, and by arranging the protective unit inside the back cover, the problem of the recorder being too bloated and inconvenient to use is reduced.
