Description

Technical Field

[0001] This invention relates to the field of dashcams, and more specifically, to a shake-resistant dashcam. Background Technology

[0002] A dashcam is an instrument that records images and sounds during a vehicle's journey. After installation, it can record video images and sounds of the entire driving process, providing evidence for determining liability in traffic accidents. People who enjoy road trips can also use it to record the process of overcoming difficult obstacles. It records video while driving, capturing time, speed, and location, much like a "black box."

[0003] However, existing dash cams have poor installation stability and cannot prevent the dash cam from shaking, which can easily cause unstable recording of the dash cam's image and affect its use.

[0004] Chinese patent CN219122735U discloses a shake-resistant dashcam. By using shock-absorbing resistance devices and two springs at the top and bottom of the dashcam body, the stability of the dashcam body is effectively improved, preventing the dashcam body from shaking.

[0005] While the aforementioned patents can improve the stability of dashcams to some extent, thereby improving the clarity of dashcam footage, the shock absorption effect is limited because the springs used for buffering do not dissipate the impact force. Furthermore, for some dashcams installed outside the vehicle, the large temperature difference in autumn and winter can cause water vapor to form on the dashcam lens, severely affecting the clarity of the footage. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of this invention is to provide a shake-resistant dashcam that can improve the clarity of the dashcam image.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A shake-resistant dashcam includes: a housing;

[0009] The image stabilization mechanism includes a first elastic pad fixedly installed on the top wall of the housing, a recorder body fixedly installed on the bottom wall of the first elastic pad, a second elastic pad fixedly installed on the bottom wall of the recorder body and the bottom wall of the housing, a communication port that mates with the recorder body is opened on the side wall of the housing, and a lens that is electrically connected to the recorder body is fixedly installed on the side wall of the recorder body.

[0010] The linkage mechanism includes a drying trough formed on the side wall of the housing, and an arc-shaped groove connected to the communication port is formed on the side wall of the drying trough. A first cavity is formed on the first elastic pad, and an air inlet valve and an air outlet valve are respectively inserted into the side wall of the first cavity. A first air pipe connected to the drying trough is fixedly installed on the output end of the air outlet valve.

[0011] Furthermore, a limiting cylinder is uniformly fixedly installed on the inner top wall of the housing, and a limiting rod that cooperates with the limiting cylinder is uniformly installed on the top wall of the recorder body. A first friction ring is fixedly installed on the inner wall of the limiting cylinder, and a second friction ring that slides and cooperates with the first friction ring is sleeved on the limiting rod.

[0012] Furthermore, symmetrical grooves are provided on the side wall of the housing, a sealing plate is slidably installed in the groove, a spring is fixedly installed between the bottom wall of the groove and the sealing plate, a magnet is embedded in the sealing plate, and a coil that cooperates with the magnet is embedded in the housing.

[0013] Furthermore, a brush plate that mates with the lens is detachably mounted on the sealing plate, and brush bristles are evenly installed on the side wall of the brush plate.

[0014] Furthermore, a sleeve is embedded in the bottom wall of the housing, a piston rod is slidably installed inside the sleeve, a horizontal rod is fixedly installed on the output end of the piston rod, and a scraper is fixedly installed on the end of the horizontal rod away from the piston rod.

[0015] Furthermore, a second cavity is provided on the second elastic pad, and a second air tube communicating with the sleeve is inserted into the side wall of the second cavity.

[0016] Furthermore, an installation port communicating with the housing is provided on the bottom wall of the housing, and a collection box is detachably installed in the installation port, and a filter screen is detachably installed in the collection box.

[0017] Furthermore, a third air pipe connected to the collection box is inserted into the input end of the air intake valve, and the end of the third air pipe near the collection box is located below the filter screen.

[0018] Furthermore, a filter plate is embedded in the side wall of the housing on the side away from the sealing plate.

[0019] Furthermore, the sidewall of the arc-shaped groove forms a 60-degree angle with the horizontal plane.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) This solution sets up a first elastic pad and a second elastic pad. During the shaking of the housing, the first elastic pad and the second elastic pad deform and buffer the recorder body, thereby reducing the shaking of the recorder body. At the same time, during the compression of the first elastic pad, the gas in the first cavity flows to the drying tank through the exhaust valve and the first air pipe and blows to the lens through the arc groove. By blowing air onto the lens, the water mist on the lens surface can be dried, thereby effectively preventing water mist from adhering to the lens surface and affecting the image clarity. At the same time, the process of drying the lens utilizes the impact force of the recorder body, thereby consuming the impact force received by the recorder body, thereby reducing the impact force received by the recorder body, that is, reducing the shaking of the recorder body, and playing a role in improving the image clarity.

[0022] (2) This solution sets up a first friction ring and a second friction ring. During the vibration of the limiting cylinder, the first friction ring and the second friction ring are driven to rub against each other, which can increase the resistance of the recorder body to vibration. When the road is bumpy, the first friction ring and the second friction ring will rub against each other quickly and generate heat. Then, the heated first friction ring and the second friction ring can heat the gas in the first cavity, thereby improving the drying effect of the lens. At the same time, the friction and heating process of the first friction ring and the second friction ring utilizes the impact force on the recorder body. According to the law of conservation of energy, the friction and heating process of the first friction ring and the second friction ring can weaken the impact force on the recorder body, thereby reducing the vibration of the recorder body and improving the image clarity.

[0023] (3) This solution uses the combination of magnet and coil. Under the action of magnetic field, the magnet drives the sealing plate to move downward. At this time, the spring is squeezed and has the tendency to recover. When the recorder body is finished, the recorder body is powered off and the magnetic field disappears. Then the spring extends and drives the sealing plate to reset. During the process of the sealing plate resetting, the connection port is gradually blocked and the lens is isolated from the outside world. This effectively prevents external dust from adhering to the lens surface and affecting the image clarity. It can also prevent naughty children from hanging pictures on the lens, thus improving the image clarity.

[0024] (4) This solution uses a brush plate to move the brush bristles up and down as the sealing plate moves up and down. When the brush bristles pass the lens, they can remove the dirt on the lens surface from the lens, thereby effectively preventing the dirt on the lens surface from affecting the image clarity and improving the image clarity.

[0025] (5) This solution uses a scraper to allow gas in the second cavity to flow into the sleeve through the second air pipe during the contraction of the second elastic pad, causing the piston rod to move upward along the inner wall of the sleeve. During the movement of the piston rod, the scraper moves upward through the horizontal rod. During the extension of the second elastic pad, the second cavity draws air from the sleeve through the second air pipe, causing the piston rod to move downward along the inner wall of the sleeve. During the movement of the piston rod, the scraper moves downward through the horizontal rod. Then, during the up-and-down movement of the scraper, the dirt adhering to the surface of the brush bristles can be cleaned, which improves the cleaning effect of the brush bristles.

[0026] (6) This solution, by setting up an air intake valve and a third air pipe, allows the airflow to carry dust that has detached from the brush bristles into the collection box and adhere to the filter surface during the process of the first elastic pad drawing air from the housing. This effectively prevents fine dust particles that have detached from the brush bristles from flying around and affecting the cleaning efficiency of the user, and also prevents dust that has been flying around from entering the recorder body and affecting the normal use of the recorder body. It can also accelerate the airflow inside the housing, thereby accelerating the heat dissipation effect of the recorder body. At the same time, it can also accelerate the airflow near the brush bristles. When there are water stains on the surface of the brush bristles, it can accelerate the evaporation of moisture on the surface of the brush bristles, thus improving the cleaning effect of the brush bristles.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 7 A shake-resistant dashcam includes: a housing 1;

[0038] The image stabilization mechanism includes a first elastic pad 2 fixedly installed on the top wall of the housing 1, a recorder body 3 fixedly installed on the bottom wall of the first elastic pad 2, a second elastic pad 4 fixedly installed on the bottom wall of the recorder body 3 and the bottom wall of the housing 1, a communication port that cooperates with the recorder body 3 is opened on the side wall of the housing 1, and a lens 5 electrically connected to the recorder body 3 is fixedly installed on the side wall of the recorder body 3.

[0039] The linkage mechanism includes a drying groove 6 formed on the side wall of the housing 1, and an arc-shaped groove 7 connected to the communication port is formed on the side wall of the drying groove 6. A first cavity 8 is formed on the first elastic pad 2. An air inlet valve 9 and an air outlet valve 10 are respectively inserted on the side wall of the first cavity 8. A first air pipe 11 connected to the drying groove 6 is fixedly installed on the output end of the air outlet valve 10.

[0040] Limiting cylinders 12 are uniformly fixedly installed on the inner top wall of the housing 1. Limiting rods 13 that cooperate with the limiting cylinders 12 are uniformly installed on the top wall of the recorder body 3. A first friction ring 14 is fixedly installed on the inner wall of the limiting cylinder 12. A second friction ring 15 that slides and cooperates with the first friction ring 14 is sleeved on the limiting rod 13.

[0041] In use, the housing 1 is first installed on the vehicle. When the vehicle shakes, the housing 1 will vibrate. During the vibration of the housing 1, the first elastic pad 2 and the second elastic pad 4 deform and tend to recover. During the deformation of the first elastic pad 2 and the second elastic pad 4, the impact force during the shaking can be buffered, thereby reducing the impact force on the recorder body 3. This reduces the vibration of the recorder body 3 and effectively prevents damage to the internal parts of the recorder body 3 due to excessive shaking, thus extending the service life of the recorder body 3. At the same time, it can also effectively prevent the shaking of the recorder body 3 from affecting the image clarity, thereby improving the image clarity.

[0042] During the upward shaking of the housing 1, the inertial recorder body 3 tends to maintain its original shape. At this time, the first elastic pad 2 is stretched and the second elastic pad 4 is compressed. During the stretching of the first elastic pad 2, the first cavity 8 draws in air through the air intake valve 9. During the downward shaking of the housing 1, the recorder body 3 tends to maintain its original shape. At this time, the first elastic pad 2 is compressed and the second elastic pad 4 is stretched. During the compression of the first elastic pad 2, the gas in the first cavity 8 flows to the drying tank 6 through the exhaust valve 10 and the first air pipe 11, and is blown towards the lens 5 through the arc-shaped groove 7. Since the lens 5 is exposed to the outside world, and In autumn and winter, the temperature difference between day and night is large, and water vapor easily adheres to the surface of lens 5. Also, when it rains, some rainwater inevitably splashes onto the surface of lens 5. Blowing air onto lens 5 can dry the water vapor on its surface, thus effectively preventing water vapor from affecting image clarity. At the same time, the process of drying lens 5 utilizes the impact force on the recorder body 3, thereby dissipating the impact force received by the recorder body 3 and reducing the vibration of the recorder body 3, which improves image clarity.

[0043] During the up-and-down shaking of the housing 1, the limiting cylinder 12 slides up and down along the limiting rod 13, and at this time, the connecting port and the lens 5 are relatively displaced, thereby limiting the recorder body 3 and effectively preventing the recorder body 3 from shifting during the shaking of the housing 1 and causing the recorder body 3 to get stuck with the housing 1, affecting the buffering effect. During the shaking of the limiting cylinder 12, the first friction ring 14 and the second friction ring 15 rub against each other, thereby increasing the resistance of the recorder body 3 during shaking. When the road is bumpy, the first friction ring 14 and the second friction ring 15 will rub against each other quickly and generate heat. Then, the heated first friction ring 14 and the second friction ring 15 can heat the gas in the first cavity 8, thereby improving the drying effect of the lens 5. At the same time, the friction and heating process of the first friction ring 14 and the second friction ring 15 utilizes the impact force on the recorder body 3. According to the law of conservation of energy, the friction and heating process of the first friction ring 14 and the second friction ring 15 can weaken the impact force on the recorder body 3, thereby reducing the shaking of the recorder body 3 and improving the image clarity.

[0044] like Figure 5 , Figure 6 As shown, the side wall of the housing 1 is symmetrically provided with sliding grooves 16, a sealing plate 17 is slidably installed in the sliding grooves 16, a spring 18 is fixedly installed between the bottom wall of the sliding grooves 16 and the sealing plate 17, a magnet 19 is embedded in the sealing plate 17, and a coil 20 that cooperates with the magnet 19 is embedded in the housing 1.

[0045] A brush plate 21 that mates with the lens 5 is detachably mounted on the sealing plate 17, and brush bristles 22 are evenly mounted on the side wall of the brush plate 21.

[0046] By adopting the above technical solution, when the recorder body 3 is powered on and started, the coil 20 is electrically connected to the recorder body 3. Then the coil 20 is energized and generates a magnetic field. Under the action of the magnetic field, the magnet 19 drives the sealing plate 17 to move downward. At this time, the spring 18 is squeezed and has a tendency to return to its original state. When the recorder body 3 is finished using, the recorder body 3 is powered off and the magnetic field disappears. Then the spring 18 extends and drives the sealing plate 17 to reset. During the reset process of the sealing plate 17, the connection port is gradually blocked and the lens 5 is isolated from the outside world. This effectively prevents external dust from adhering to the surface of the lens 5 and affecting the image clarity. It can also prevent naughty children from scratching the lens 5, thus improving the image clarity.

[0047] When it rains, dirty water will inevitably splash onto the surface of lens 5. Although blowing air onto the surface of lens 5 can dry the moisture, the dust and stains in the dirty water will still adhere to the surface of lens 5. Then, as the sealing plate 17 moves up and down, the brush plate 21 drives the brush bristles 22 to move up and down. When the brush bristles 22 pass over lens 5, they can remove the stains on the surface of lens 5 from the lens 5, thereby effectively preventing the stains on the surface of lens 5 from affecting the image clarity and improving the image clarity.

[0048] like Figure 2 , Figure 5 As shown, a sleeve 23 is embedded in the bottom wall of the housing 1, a piston rod 24 is slidably installed inside the sleeve 23, a horizontal rod 25 is fixedly installed on the output end of the piston rod 24, and a scraper 26 is fixedly installed on the end of the horizontal rod 25 away from the piston rod 24.

[0049] A second cavity 27 is provided on the second elastic pad 4, and a second air pipe 28 communicating with the sleeve 23 is inserted into the side wall of the second cavity 27.

[0050] The bottom wall of the housing 1 has an installation port that communicates with the housing 1. A collection box 29 is detachably installed in the installation port, and a filter screen 32 is detachably installed in the collection box 29.

[0051] A third air pipe 30, which communicates with the collection box 29, is inserted into the input end of the air intake valve 9, and the end of the third air pipe 30 near the collection box 29 is located below the filter screen 32.

[0052] A filter plate 31 is embedded in the side wall of the housing 1 on the side away from the sealing plate 17.

[0053] By adopting the above technical solution, during the contraction of the second elastic pad 4, the gas in the second cavity 27 flows into the sleeve 23 through the second air pipe 28, increasing the pressure inside the sleeve 23. Then, under the action of the pressure, the piston rod 24 begins to move upward along the inner wall of the sleeve 23. During the movement of the piston rod 24, the scraper 26 moves upward through the horizontal rod 25. During the extension of the second elastic pad 4, the second cavity 27 draws air from the sleeve 23 through the second air pipe 28, creating a negative pressure inside the sleeve 23. Then, under the action of the pressure, the piston rod 24 begins to move downward along the inner wall of the sleeve 23. During the movement of the piston rod 24, the scraper 26 moves downward through the horizontal rod 25. During the up-and-down movement of the scraper 26, the dirt adhering to the surface of the bristles 22 can be cleaned, thereby improving the cleaning effect of the bristles 22.

[0054] Under the influence of gravity, dirt that has detached from the bristles 22 falls into the collection box 29. Users can then remove the collection box 29 and clean the dirt inside, thus facilitating the cleaning process. During the extension of the first elastic pad 2, the first cavity 8 draws air from the housing 1 through the air inlet valve 9, the third air pipe 30, the collection box 29, and the filter screen 32. As the airflow passes through the filter screen 32 and the collection box 29 and is drawn into the third air pipe 30, it can carry dust that has detached from the bristles 22 into the collection box 29 and adhere to the surface of the filter screen 32. This effectively prevents fine dust particles that have detached from the bristles 22 from scattering everywhere and affecting the user's cleaning efficiency. It also prevents dust that has scattered everywhere from entering the recorder body 3 and affecting the normal use of the recorder body 3. This ensures the normal use of the recorder body 3 while facilitating the user's cleaning of dirt.

[0055] During the process of air being drawn from the housing 1 through the first cavity 8 via the intake valve 9, the third air pipe 30, the collection box 29, and the filter screen 32, the pressure inside the housing 1 decreases. Then, under the action of the pressure, the external airflow enters the housing 1 through the filter plate 31, thereby accelerating the airflow speed inside the housing 1, which improves the heat dissipation effect of the recorder body 3. At the same time, during the process of air being drawn from the housing 1 through the first cavity 8 via the intake valve 9, the third air pipe 30, the collection box 29, and the filter screen 32, the airflow speed near the bristles 22 can be accelerated. When there are water stains remaining on the surface of the bristles 22, the evaporation of the moisture on the surface of the bristles 22 can be accelerated, which improves the cleaning effect of the bristles 22. This improves both the cleaning effect of the bristles 22 and the heat dissipation effect of the recorder body 3.

[0056] like Figure 4 As shown, the sidewall of the arc-shaped groove 7 forms a 60-degree angle with the horizontal plane.

[0057] By adopting the above technical solution, when the surface of the lens 5 is dried in the first cavity 8 through the exhaust valve 10, the first air pipe 11, the drying tank 6, and the arc groove 7, the airflow can be directly blown onto the surface of the lens 5 by making the side wall of the arc groove 7 form a 60-degree angle with the horizontal plane, thereby improving the drying effect.

[0058] Instructions for use: First, install the housing 1 on the vehicle. During vehicle vibration, the first elastic pad 2 and the second elastic pad 4 deform and tend to recover, thus buffering the impact on the recorder body 3 and reducing vibration. Simultaneously, as the first elastic pad 2 is compressed, the gas in the first cavity 8 flows through the exhaust valve 10 and the first air pipe 11 to the drying tank 6 and is blown onto the lens 5 through the arc-shaped groove 7. Blowing air onto the lens 5 dries the water mist on its surface, effectively preventing water mist from affecting image clarity. When the road is bumpy, the first friction ring 14 and the second friction ring 15 will quickly rub together. The friction rings 14 and 15, which generate heat through friction, can heat the gas in the first cavity 8, thereby improving the drying effect of the lens 5. At the same time, the friction and heating process of the first friction rings 14 and 15 utilizes the impact force on the recorder body 3. According to the law of conservation of energy, the friction and heating process of the first friction rings 14 and 15 can weaken the impact force on the recorder body 3. After the recorder body 3 is used, the connection port is gradually sealed and the lens 5 is isolated from the outside world during the resetting process of the sealing plate 17. During the movement of the sealing plate 17, the bristles 22 are driven to clean the dirt on the surface of the lens 5.

[0059] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
