Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted recording equipment, and in particular to a vehicle-mounted audio and video recording device for intelligent vehicle monitoring and management. Background Art

[0002] As people's living standards improve, the purchase and use rates of cars are getting higher and higher, and the incidence of scratches, traffic accidents, etc. is also increasing accordingly. In order to record the images and sounds of the vehicle in real time during driving and provide the driver with effective driving evidence, on-board audio and video recording equipment is widely used.

[0003] Existing on-vehicle audio and video recording equipment usually focuses on the situation in front of the vehicle. However, when the vehicle is hit, the recording equipment cannot record the driver's operations and reactions when the vehicle is hit, and cannot provide a more comprehensive basis for the determination of accident responsibility. At the same time, when hit, the driver will become unconscious or even fall into a coma. This sudden physical condition will seriously affect the driver's accurate judgment of the current situation, making it impossible for the driver to make correct responses in time, increasing the possibility of driver misoperation leading to more serious consequences.

[0004] In addition, existing vehicle-mounted video recording equipment is usually fixed to the inside of the vehicle by suction cups or adhesive fixation. When the vehicle is hit, the impact force increases the risk of the video recording equipment falling off. Once the video recording equipment falls off, not only will the video recording work fail to be completed, but data transmission will also be interrupted due to damage during the falling process, making it impossible to accurately record the situation when the accident occurred, affecting the determination of the cause and responsibility of the accident.

[0005] Therefore, a vehicle-mounted audio and video recording device for intelligent vehicle monitoring and management is proposed. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When a vehicle is hit from the side, the camera can turn to the driver in time to shoot the situation inside the car, and then can record the driver's behavior and state when the accident occurs in time, so as to provide evidence for the cause of the accident. At the same time, during the rotation of the camera, the liquid with a pungent smell can wash the surface of the camera, wash away the dust accumulated on the surface of the camera, and also settle the dust near the camera. In addition, the pungent smell emitted by the liquid can also keep the driver awake to a certain extent, reducing the risk of more serious consequences caused by the driver's unclear consciousness and inability to make correct judgments in time;

[0017] 2. When the vehicle is hit, the reinforcement plate quickly moves upward and the top of the reinforcement box is designed to be wide at the bottom and narrow at the top, so that the glue inside the reinforcement box can be quickly sprayed from the connecting hose to the contact surface between the fixing plate and the vehicle. Compared with the existing vehicle-mounted video recording equipment that only has the function of sticking and fixing but lacks the reinforcement function in emergency situations, it can timely increase the stability of the fixing plate when the vehicle is hit, avoiding the loosening and falling of the recording subject due to the impact, and failing to record the internal situation of the vehicle in time when the accident occurs, so as to assist in the determination of accident responsibility;

[0018] 3. By following the rotation of the recording subject, the liquid in the liquid storage tank can be used to flush the camera surface, and the reciprocating movement of the cleaning sponge after flushing can timely wipe the residual moisture on the camera surface. No additional drive is required to remove dust and residual moisture on the camera surface, avoiding the presence of water stains that affect the camera's shooting effect, thereby effectively recording the interior of the vehicle. At the same time, the used cleaning sponge is reset to the inside of the cleaning shell, which will not affect the normal use of the camera. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The liquid outlet at the bottom of the liquid storage tank 32 is located above the camera 15 , and the liquid stored in the liquid storage tank 32 is a liquid with a pungent odor.

[0041] The reinforcement assembly includes a reinforcement box 41, which is fixedly connected to the top of the driving box 21. The top of the inner cavity of the reinforcement box 41 is set to a funnel shape that is wide at the bottom and narrow at the top. A reinforcement spring 42 is fixedly connected to the bottom of the inner wall of the reinforcement box 41, and a reinforcement plate 43 is fixedly connected to the top of the reinforcement spring 42.

A connecting hose 47 is fixedly connected to the top of the reinforcement box 41, and the other end of the connecting hose 47 is interconnected with the fixed plate 14.

[0042] The liquid stored in the reinforcement box 41 is glue, and the guide chute 46 includes an inclined chute and a straight chute.

[0043] The above implementation works as follows:

[0044] The initialization steps are as follows:

[0045] The user tears off the protective film on the surface of the fixing plate 14, and sticks the recording body 1 to a suitable position on the front side of the vehicle through the adhesive plate of the fixing plate 14. In the initial state, the camera 15 faces the direction of vehicle travel, the driving spring 23 is in an extended state, the clamping block 29 and the fixing groove 27 are in a clamping state, the sliding baffle 33 blocks the liquid outlet at the bottom of the liquid storage tank 32, the linkage slide rod 35 is located inside the driving groove frame 36, the cleaning sponge 37 is located inside the cleaning shell 31, the top end of the clamping slide rod 44 is clamped with the reinforcing plate 43 through the clamping groove on the reinforcing plate 43, and the bottom end of the clamping slide rod 44 is located inside the inclined groove of the guide slide groove 46.

[0046] The working steps are as follows:

[0047] The following is an explanation of the process by which the steering component turns in time to record the situation inside the vehicle when a vehicle crashes:

[0048] like Figures 2 to 5 As shown, when the vehicle is hit, the vehicle itself will shake violently, and the shaking of the vehicle will cause the recording body 1 inside it to shake. Under the action of the violent shaking, the driving slide bar 26 has a tendency to slide along the steering slide groove 25 inside the steering slide groove 25. The sliding tendency of the driving slide bar 26 causes the groove wall of the fixed groove 27 to resist the clamping block 29, causing the clamping block 29 to slide away from the driving slide bar 26 and compress the clamping spring 28. At this time, the clamping block 29 is no longer clamped with the driving slide bar 26, and the driving slide bar 26 will slide inside the steering slide groove 25. Because the steering slide groove 25 is set as a U-shaped groove, when the driving slide bar 26 slides to the vertical part of the U-shaped groove, the groove wall of the steering slide groove 25 no longer resists the driving slide bar. 26. At this time, under the elastic contraction of the driving spring 23, the linkage tooth plate 24 slides in the direction of the linkage slide plate 45 inside the driving box 21. Because the linkage gear 22 is located on the moving path of the linkage tooth plate 24, when the linkage tooth plate 24 slides to engage with the linkage gear 22, the sliding of the linkage tooth plate 24 causes the linkage gear 22 to start rotating. The rotation of the linkage gear 22 drives the connecting shaft 11 fixedly connected thereto to rotate on the surface of the rotating shaft 12. The rotation of the connecting shaft 11 drives the video recording body 1 fixedly connected thereto to rotate. The rotation of the video recording body 1 causes the camera 15 to face the driver. Therefore, when a car accident occurs, the video recording body 1 can timely record the situation inside the car, providing a basis for analyzing the cause of the accident.

[0049] The following is an explanation of the process of cleaning the camera 15 by the cleaning component:

[0050] When the vehicle is hit, dust in every corner of the vehicle becomes loose and suspended in the air, which reduces the clarity of the vehicle interior environment. The increase in suspended dust also increases the dust accumulated on the surface of the camera 15 , affecting the shooting effect of the camera 15 .

[0051] like Figures 6 to 9 As shown, the sliding of the linkage tooth plate 24 drives the driving slot frame 36 fixedly connected thereto to move synchronously. Since the linkage slide bar 35 is located inside the driving slot frame 36, the movement of the driving slot frame 36 causes its inner wall to contact the linkage slide bar 35 and push the linkage slide bar 35 to move in the direction of the rotating shaft 12. The movement of the linkage slide bar 35 drives the connecting slide bar 34 to move in the direction of the rotating shaft 12 inside the camera body 1. The movement of the connecting slide bar 34 drives the sliding baffle plate 33 fixedly connected thereto to move in the direction of the camera body 1 inside the liquid storage tank 32. At this time, the sliding baffle plate 33 no longer blocks the liquid outlet at the bottom of the liquid storage tank 32. The liquid inside the liquid storage tank 32 flows out from the liquid outlet to the surface of the camera head 15, washing away the dust and impurities on the surface of the camera head 15. The outflow of liquid from the liquid storage tank 32 is also beneficial to the sedimentation of dust near the video subject 1, thereby improving the clarity of the video footage taken by the video subject 1. In addition, the liquid inside the liquid storage tank 32 contains a pungent odor. When the driver becomes unconscious or unconscious due to the impact of the vehicle, the pungent odor can keep the driver awake to a certain extent, so that the driver can make a correct judgment on the current situation and avoid more serious consequences. When the video subject 1 rotates to drive the linkage slide bar 35 to rotate around the rotating shaft 12, because the driving slot frame 36 is set as an arc-shaped plate, the end of the linkage slide bar 35 close to the driving slot frame 36 will rotate away from the inside of the driving slot frame 36, and the driving slot frame 36 will not hinder the rotation of the linkage slide bar 35.

[0052] At the same time, the rotation of the recording body 1 drives the cleaning gear 315 to rotate around the rotating shaft 12. When all the liquid in the liquid storage tank 32 flows out, the arc-shaped toothed plate 316 is located on the moving path of the cleaning gear 315. At this time, the rotation of the cleaning gear 315 makes it mesh with the arc-shaped toothed plate 316. During the rotation of the cleaning gear 315, the cleaning gear 315 starts to rotate. The rotation of the cleaning gear 315 drives the active belt shaft bevel gear 314 fixedly connected to it to rotate synchronously. The rotation of the active belt shaft bevel gear 314 drives the driven bevel gear 313 meshing with it to rotate synchronously. The rotation of the driven bevel gear 313 drives the linkage turntable 310 fixedly connected to it to rotate one circle inside the fixed bracket 39. The rotation of the fixed bracket 39 drives the fixed The circular block 311 rotates around the center of the linkage turntable 310, and the rotation of the fixed circular block 311 drives the linkage rotating rod 312 to rotate and move up and down reciprocatingly. The up and down reciprocating movement of the linkage rotating rod 312 drives the cleaning slide bar 38 to move up and down inside the cleaning shell 31. The reciprocating movement of the cleaning slide bar 38 drives the cleaning sponge 37 fixedly connected thereto to move up and down reciprocatingly. When the cleaning sponge 37 moves down and leaves the inside of the cleaning shell 31, the cleaning sponge 37 will fit together with the surface of the camera 15, and take away excess moisture on the surface of the camera 15, avoiding the presence of water stains that affect the shooting effect of the camera 15, ensuring the imaging quality, and being able to effectively record the interior of the vehicle. After the cleaning sponge 37 is wiped, the cleaning sponge 37 moves up and resets to the inside of the cleaning shell 31.

[0053] The following is an explanation of the process of reinforcing the components to enhance the stability of the recording subject 1:

[0054] When a vehicle is impacted by a collision, the dashcam that was originally well-attached may become loose and fall off due to the impact of the collision.

[0055] like Figure 10 to Figure 11As shown, when the linkage tooth plate 24 slides inside the drive box 21, the sliding of the linkage tooth plate 24 drives the linkage slide plate 45 fixedly connected thereto to slide in the direction of the reinforcement spring 42, and the sliding of the linkage slide plate 45 drives the guide slide groove 46 to move synchronously. Because the bottom end of the card-connecting slide rod 44 is located at the inclined groove part inside the guide slide groove 46, at this time, the inclined groove wall inside the guide slide groove 46 will push the card-connecting slide rod 44 to slide away from the reinforcement plate 43 into the straight groove part of the guide slide groove 46. At this time, the movement of the linkage slide plate 45 will no longer push the card-connecting slide rod 44, and at the same time, the sliding of the card-connecting slide rod 44 makes it no longer carded with the card groove of the reinforcement plate 43. At this time, under the elastic extension action of the reinforcement spring 42, the reinforcement plate 43 quickly slides upward inside the reinforcement box 41, pushing the reinforcement box 41 inside. The glue liquid accelerates to move toward the top of the inner cavity of the reinforcement box 41. At the same time, the top of the inner cavity of the reinforcement box 41 is set to be a funnel shape that is wide at the bottom and narrow at the top. When the fluid passes through a pipeline or a flow device, if the cross-sectional area becomes narrower, for example, the pipeline shrinks, according to the continuity equation, the mass flow rate remains constant. Since the mass flow rate is proportional to the speed, when the speed increases, the flow rate of the fluid through the narrow part will also increase. According to the principle of conservation of energy, as the speed increases, the kinetic energy of the fluid will also increase. Then, the glue liquid inside the reinforcement box 41 will accelerate to enter the interior of the connecting hose 47 and spray toward the contact surface between the fixing plate 14 and the vehicle, thereby increasing the stability of the fixing plate 14 and avoiding the inability to record the internal conditions of the vehicle in time when a car accident occurs due to the loosening and falling of the recording subject 1, so as to assist in the determination of accident responsibility.
