Description

Technical Field

[0001] The invention relates to the technical field of vehicle accessories, and in particular to a multi-angle adjustable driving recorder. Background Art

[0002] With the continuous increase in the number of cars, the demand for road traffic safety and evidence recording during vehicle driving has become increasingly prominent. As a device that can record relevant information such as images and sounds while the vehicle is driving, the driving recorder has become an important tool for many car owners to protect their own rights and interests and maintain driving safety.

[0003] At present, the shooting angles of most driving recorders on the market lack flexibility and are difficult to adjust dynamically according to the real-time driving status of the vehicle. When the vehicle turns, due to the fixed shooting angle, the recorder cannot synchronously follow the vehicle's turning and change the viewing angle, resulting in an offset in the shooting picture. The road conditions and surrounding environment that should have been fully recorded can only be captured partially, and there is an obvious blind spot in the field of vision. This may cause the omission of key driving information when driving on complex urban roads or narrow curves, such as violations of other vehicles and obstacles on the road, which brings difficulties to the determination of accident responsibility and subsequent handling. Similarly, when the vehicle goes up and down steep slopes, the fixed shooting angle cannot adapt to the tilt of the vehicle, so that the shooting picture cannot accurately reflect the actual situation in front of and around the vehicle.

[0004] Therefore, how to realize that the driving recorder can dynamically adjust the shooting angle according to the real-time driving status of the vehicle, and then completely save the driving information of the vehicle under complex road conditions, is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In order to completely preserve the driving information of the vehicle under complex road conditions and enable the vehicle recorder to dynamically adjust the shooting angle according to the real-time driving status of the vehicle, the present application provides a multi-angle adjustable driving recorder.

[0006] The multi-angle adjustable driving recorder provided in this application adopts the following technical solution: A multi-angle adjustable driving recorder comprises a mounting base, a first rotating component is mounted on the mounting base, a second rotating component is mounted on the first rotating component, the first rotating component rotates in a horizontal direction, the second rotating component rotates in a vertical direction, and a camera is mounted on the second rotating component; a swing detection component and a tilt detection component for detecting the driving state of a vehicle are installed inside the mounting base, and the first rotating component, the second rotating component, the swing detection component and the tilt detection component are electrically connected to a controller.

[0007] By adopting the above technical solution, using the swing detection component and the tilt detection component to work in conjunction with the first rotating component and the second rotating component, it can be ensured that when the vehicle turns or goes up and down steep slopes, the camera always maintains the best shooting angle, avoids the shooting image from being offset due to changes in the vehicle's driving state, and completely records the vehicle's surroundings, providing more comprehensive and accurate image data for accident responsibility determination, etc.

[0008] Furthermore, the first rotating component includes a support frame fixedly mounted on the mounting seat, the support frame is rotatably connected to a horizontally arranged turntable, the second rotating component is fixedly mounted on the turntable, the outer side surface of the turntable is fixedly connected to a gear ring, a first driving member electrically connected to the controller is fixedly mounted on the support frame, a driving gear is fixedly mounted on the first driving member, and the driving gear is meshed with the gear ring.

[0009] By adopting the above technical solution and utilizing the meshing transmission mode of the active gear and the gear ring, more precise angle control can be achieved. Different changes in the vehicle's driving state correspond to different electrical signal instructions. The first drive member can accurately control the number of turns and angles of the active gear according to the instructions, and then accurately drive the turntable to rotate, so that the camera can accurately adjust to the appropriate horizontal shooting angle, ensuring that the shooting picture always covers the key area, and providing more accurate image data for accident recording, etc. In addition, the first drive member is electrically connected to the controller and can quickly respond to the instructions issued by the controller. In the case of frequent changes in the vehicle's driving state, the rotation angle of the turntable can be quickly adjusted, so that the camera can change the shooting direction in time according to the vehicle's driving state, meeting the needs of the driving recorder for multi-angle and fast adjustment of shooting angles under complex road conditions.

[0010] Furthermore, the second rotating component includes a mounting frame, the mounting frame is fixedly mounted on the first rotating component, the mounting frame is rotatably connected to a rotating shaft, the rotating shaft is fixedly connected to a camera mounting seat, the camera is fixedly mounted inside the camera mounting seat, the rotating shaft passes through the outer end of the mounting frame and is fixedly connected to a driven pulley, a second driving member electrically connected to the controller is fixedly mounted on the mounting frame corresponding to the driven pulley, a driving pulley is fixedly mounted on the second driving member, and a toothed belt is transmission-connected between the driving pulley and the driven pulley.

[0011] By adopting the above technical solution and using the belt drive method, the camera can be more flexibly adjusted in the vertical direction. In different tilt states such as when the vehicle is going up or down a steep slope, the controller can accurately control the operation of the second drive member according to the signal of the tilt detection component, so that the camera can be quickly and accurately adjusted to a suitable shooting angle, avoiding the deviation of the shooting picture due to the tilt of the vehicle, and ensuring that the front and surrounding conditions of the vehicle can always be recorded clearly and completely. In addition, the toothed belt drive has the characteristics of smooth transmission, which can effectively reduce vibration and noise during the transmission process. During the driving process of the vehicle, the smooth transmission can ensure that the camera will not shake violently during the angle adjustment process, making the shooting picture more stable and improving the shooting quality of the driving recorder.

[0012] Furthermore, the swing detection assembly includes a swing rod, which is centrally rotatably connected to the mounting base, and a driving gear is fixedly connected to the swing rod along its rotation center. A first sensor electrically connected to the controller is fixedly installed on the mounting base corresponding to the driving gear, and a driven gear is fixedly installed on the detection shaft of the first sensor, and the driven gear is meshed with the driving gear. The first sensor is used to detect the rotation angle of the driven gear.

[0013] By adopting the above technical solution, using the gear meshing transmission and the precise detection of the first sensor, the swing angle information of the swing lever can be accurately obtained, providing accurate data support for the system, which is helpful for accurately controlling and adjusting the swing state of related equipment. In addition, the first sensor can detect the rotation angle of the driven gear in real time, and then reflect the swing state of the swing lever in real time, so that the controller can make corresponding decisions and adjustments in time according to the detected information, and realize real-time monitoring and dynamic control of the entire system.

[0014] Furthermore, both ends of the swing arm are fixedly connected with tension springs, one end of the tension spring away from the swing arm is fixedly connected to the inner wall of the mounting seat, and counterweight blocks are fixedly connected to the swing arm near its two ends.

[0015] By adopting the above technical solution, the elastic force of the tension spring can limit the swing range of the swing rod, prevent it from swinging too much, ensure that the swing is carried out within a specified reasonable range, and avoid collision or damage with other components caused by excessive swinging. The counterweight block can increase the moment of inertia, make the swing rod more stable during the swing process, reduce unnecessary vibration and shaking, and help improve the stability and reliability of the entire swing detection component and related systems.

[0016] Furthermore, the tilt detection component includes a sealing box fixedly mounted on the mounting seat, the length direction of the sealing box is parallel to the length direction of the vehicle body, the top of the sealing box near its two ends are sealed and fixedly connected with vertical tubes extending upward, and a detection tube is sealed and fixedly connected between the two vertical tubes; the interior of the sealing box is filled with liquid fluid, and the two vertical tubes are filled with gaseous fluid, the interior of the detection tube is sealed and slidably connected with a detection column, the outer side surface of the detection tube is provided with a slide groove in the center, the outer side surface of the detection column passes through the slide groove and is transmission-connected with a second sensor electrically connected to the controller, and the second sensor is used to detect the sliding position of the detection column inside the detection tube.

[0017] By adopting the above technical solution, the flow and pressure change of liquid fluid are used to drive the detection column, which can respond to the slight tilt of the vehicle, has high sensitivity, can accurately detect different tilt states of the vehicle such as uphill and downhill, and provide accurate tilt information for the angle adjustment of the driving recorder. In addition, the sealing structure composed of the sealing box, vertical tube and detection tube, as well as the combination of liquid fluid and gaseous fluid, makes the entire detection system have good stability.

[0018] Furthermore, the liquid fluid is configured as mercury, and the gaseous fluid is configured as nitrogen.

[0019] By adopting the above technical solution, mercury's high fluidity and high density can be used to quickly respond to the slight tilt of the vehicle and flow accurately, providing a basis for accurately detecting the tilt state of the vehicle, and making the detection results closer to the actual tilt of the vehicle. Nitrogen is stable in nature. When used as a pressure transmission medium, it can ensure the stability and accuracy of pressure changes, so that the displacement of the detection column and the vehicle tilt angle have a more accurate correspondence, thereby improving the detection accuracy.

[0020] Furthermore, the second sensor includes a brush electrically connected to the controller, the brush is installed on the outer surface of the detection column at a position in the middle thereof, the brush passes through the slide groove, and a resistor block electrically connected to the controller is fixedly installed on the outside of the detection tube corresponding to the brush, the resistor block is conductively connected to the brush, a spring is fixedly connected between the brush and the detection column, and the spring pushes the brush to abut against the resistor block.

[0021] By adopting the above technical solution, the second sensor composed of a brush, a resistor block and a spring has a relatively simple structure without complex electronic components and precision mechanical structures. This makes its manufacturing cost lower, which is conducive to reducing the cost of the entire driving recorder system and improving the market competitiveness of the product. In addition, the setting of the spring ensures that the brush always maintains good conductive contact with the resistor block. Even if there is vibration during the driving of the vehicle, the spring can make the brush stably abut against the resistor block, ensuring that the change in resistance value can accurately reflect the sliding position of the detection column, thereby ensuring the reliability and stability of the detection of the vehicle's tilt state.

[0022] Furthermore, an outer box covering the outside of the first rotating component is fixedly mounted on the top of the mounting seat, and a protective cover covering the second rotating component and the outside of the camera is mounted on the first rotating component, and the protective cover is made of transparent material.

[0023] By adopting the above technical solution, the outer box can protect the first rotating component from the intrusion of external dust, water vapor, debris, etc., reduce the wear, corrosion or failure of the components caused by external factors, extend the service life of the first rotating component, and ensure the smoothness and stability of its rotation. The protective cover provides reliable protection for the second rotating component and the camera. It can prevent stones, rain, dust, etc. splashed during the driving of the vehicle from directly hitting or contaminating the second rotating component and the camera, reduce the risk of damage caused by external impact or adhesion of pollutants, and improve the overall reliability and durability of the driving recorder.

[0024] Furthermore, a mounting groove is provided at the bottom of the mounting seat, an adhesive block is fixedly installed inside the mounting groove, the adhesive block is made of elastic material, and the adhesive layer at one end of the adhesive block is away from the mounting seat.

[0025] By adopting the above technical solution, the adhesive layer on the adhesive block is used for fixing, and no complicated installation tools and cumbersome installation steps are required. The car owner can easily complete the installation by himself, which greatly improves the installation efficiency and reduces the installation difficulty. In addition, the dashcam is installed on the roof, which is relatively high, so that the camera of the dashcam can obtain a wider viewing angle, which can not only better capture the road conditions in front of the vehicle, but also take into account the conditions on both sides of the vehicle and even the rear. It has greater advantages in recording some sudden traffic conditions, such as side vehicle collisions and rear-end collisions of rear vehicles.

[0026] Beneficial effects achieved: This application utilizes the swing detection component and the tilt detection component to work in conjunction with the first rotating component and the second rotating component, and can automatically adjust the shooting angle according to the driving state of the vehicle, so that the driving recorder can adapt to a variety of complex road conditions, and realize that the driving recorder can dynamically adjust the shooting angle according to the real-time driving state of the vehicle, thereby completely saving the driving information of the vehicle under complex road conditions. Compared with traditional fixed-angle driving recorders, the applicable scenarios have been greatly increased, whether it is frequent turns on urban roads or steep slopes on mountain roads, it can work stably; and the entire adjustment process is completed by the detection component, controller and rotating component in coordination, without manual intervention, realizing intelligent operation, reducing the burden of the driver to manually adjust the angle of the recorder during driving, and improving driving safety.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0038] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] The embodiment of the present application discloses a driving recorder with multi-angle adjustment.

[0040] Please refer to Figures 1 to 8In one embodiment of the present application, a multi-angle adjustable driving recorder includes a mounting base 100, a first rotating component 200 is mounted on the mounting base 100, a second rotating component 300 is mounted on the first rotating component 200, the first rotating component 200 rotates in a horizontal direction, the second rotating component 300 rotates in a vertical direction, and a camera 900 is mounted on the second rotating component 300; a swing detection component 400 and a tilt detection component 500 for detecting the driving state of the vehicle are installed inside the mounting base 100, and the first rotating component 200, the second rotating component 300, the swing detection component 400 and the tilt detection component 500 are electrically connected to a controller 600.

[0041] The implementation principle of a multi-angle adjustable driving recorder in the embodiment of the present application is: During operation, the swing detection component 400 is responsible for real-time monitoring whether the vehicle is in a swinging state due to turning, and the tilt detection component 500 is responsible for monitoring whether the vehicle is in a tilting state due to going up or down a steep slope. The swing detection component 400 and the tilt detection component 500 transmit the detected vehicle driving state data to the controller 600 in the form of an electrical signal. After receiving the signals from the swing detection component 400 and the tilt detection component 500, the controller 600 analyzes and processes the signals according to a preset program. If it is detected that the vehicle is turning, the controller 600 will send an electrical signal to the first rotating component 200 to drive it to rotate in the horizontal direction, thereby driving the second rotating component 300 and the camera 900 connected thereto to adjust the angle in the horizontal direction, so that the shooting angle is synchronized with the vehicle turning; if it is detected that the vehicle is going up or down a steep slope, the controller 600 will send an electrical signal to the second rotating component 300 to rotate in the vertical direction, driving the camera 900 to adjust the angle in the vertical direction to adapt to the tilt state of the vehicle.

[0042] Please refer to Figures 1 to 8 In one embodiment of the present application, an outer box 101 covering the outside of the first rotating component 200 is fixedly installed on the top of the mounting base 100, and a protective cover 102 covering the outside of the second rotating component 300 and the camera 900 is installed on the first rotating component 200, and the protective cover 102 is made of transparent material.

[0043] During operation, the outer box 101 is fixedly mounted on the top of the mounting base 100 and covers the outside of the first rotating assembly 200. It does not affect the normal rotation of the first rotating assembly 200, but only provides a relatively closed space for the first rotating assembly 200 to play a protective role. The protective cover 102 is mounted on the first rotating assembly 200 and can cover the outside of the second rotating assembly 300 and the camera 900. Since the protective cover 102 is made of transparent material, it will not block the shooting line of sight of the camera 900, and can provide protection for the second rotating assembly 300 and the camera 900.

[0044] In a specific embodiment of the present application, the transparent material is made of polymethyl methacrylate (PMMA), which is commonly known as organic glass. It has good optical transparency and a light transmittance of more than 92%, which can make the picture captured by the camera clear and distortion-free. It is relatively light in texture, with a density of about 1.18g / cm³, which is much lighter than glass and will not add too much burden to the driving recorder. At the same time, PMMA also has good weather resistance, can maintain stable performance under different temperature and humidity environments, and is not easy to turn yellow or crack. Good light transmittance can ensure that the camera shooting effect is not affected and can clearly record the situation around the vehicle. The light weight is easy to install and use, and will not have an adverse effect on the overall structure and stability of the driving recorder. It has strong weather resistance and can adapt to various complex outdoor environments, extend the service life of the protective cover, and thus ensure the normal operation of the driving recorder.

[0045] It is understandable that in other specific embodiments of the present application, the protective cover 102 may also be made of other transparent materials, such as polycarbonate (PC), glass, etc.

[0046] Please refer to Figures 1 to 8 In one embodiment of the present application, a mounting groove 103 is provided at the bottom of the mounting seat 100, and an adhesive block 104 is fixedly installed inside the mounting groove 103. The adhesive block 104 is made of elastic material, and the adhesive layer at one end of the adhesive block 104 is away from the mounting seat 100. The mounting seat 100 is fixedly bonded to the top of the vehicle through the adhesive layer on the adhesive block 104.

[0047] When in use, align the adhesive block 104 in the mounting groove 103 at the bottom of the mounting seat 100 with the position on the top of the vehicle to be installed. Since the adhesive layer is provided at one end of the adhesive block 104 away from the mounting seat 100, the mounting seat 100 is pressed, and the adhesive layer is closely attached to the top surface of the vehicle. The mounting seat 100 is firmly fixed on the top of the vehicle by utilizing the viscosity of the adhesive. During driving, the vehicle will vibrate due to bumps on the road, etc. At this time, the adhesive block 104 made of elastic material comes into play. When the vibration of the vehicle is transmitted to the mounting seat 100, the adhesive block 104 can absorb and buffer the vibration energy through its own elastic deformation, reduce the impact of the vibration on the mounting seat 100 and the entire driving recorder installed thereon, and keep the driving recorder in a relatively stable state.

[0048] Please refer to Figures 1 to 8In one embodiment of the present application, the first rotating component 200 includes a support frame 201 fixedly mounted on the mounting base 100, and a horizontally arranged turntable 202 is rotatably connected to the support frame 201. The second rotating component 300 is fixedly mounted on the turntable 202, and a gear ring 203 is fixedly connected to the outer side surface of the turntable 202. A first driving member 204 electrically connected to the controller 600 is fixedly mounted on the support frame 201, and a driving gear 205 is fixedly mounted on the first driving member 204, and the driving gear 205 is meshed with the gear ring 203.

[0049] During operation, when the vehicle's driving state changes, such as turning, the swing detection component 400 in the mounting seat 100 detects a signal and transmits it to the controller 600. After analysis and processing, the controller 600 sends an electrical signal command to the first driving member 204. After receiving the electrical signal from the controller 600, the first driving member 204 starts to operate. Since the first driving member 204 is fixedly mounted with a driving gear 205, it drives the driving gear 205 to rotate synchronously. The driving gear 205 is meshed with the ring gear 203 fixedly connected to the outer side of the turntable 202. When the driving gear 205 rotates, the ring gear 203 is driven to rotate through the meshing transmission between the gears. The ring gear 203 is fixedly connected to the turntable 202, so that the turntable 202 rotates horizontally on the support frame 201. Because the second rotating assembly 300 is fixedly mounted on the turntable 202, the rotation of the turntable 202 will drive the second rotating assembly 300 and the camera 900 mounted on the second rotating assembly 300 to rotate synchronously in the horizontal direction, thereby adjusting the shooting angle in the horizontal direction.

[0050] Please refer to Figures 1 to 8 In one embodiment of the present application, the second rotating component 300 includes a mounting frame 301, the mounting frame 301 is fixedly mounted on the first rotating component 200, the mounting frame 301 is rotatably connected to a rotating shaft 302, the rotating shaft 302 is fixedly connected to a camera mounting seat 303, the camera 900 is fixedly mounted inside the camera mounting seat 303, the rotating shaft 302 passes through the outer end of the mounting frame 301 and is fixedly connected to a driven pulley 304, a second driving member 305 electrically connected to the controller 600 is fixedly mounted on the mounting frame 301 corresponding to the driven pulley 304, a driving pulley 306 is fixedly mounted on the second driving member 305, and a toothed belt 307 is transmission-connected between the driving pulley 306 and the driven pulley 304.

[0051] During operation, when the vehicle's driving state changes, such as when going up or down a steep slope, the tilt detection component 500 detects the tilt state of the vehicle and transmits a signal to the controller 600. After analyzing and processing the signal, the controller 600 sends a corresponding electrical signal command to the second drive member 305. After receiving the command from the controller 600, the second drive member 305 starts to operate, driving the active pulley 306 fixed thereon to rotate. Since the active pulley 306 and the driven pulley 304 are connected by a toothed belt 307, the rotation of the active pulley 306 is transmitted to the driven pulley 304 through the toothed belt 307, thereby rotating the driven pulley 304. The driven pulley 304 is fixedly connected to the rotating shaft 302, and the rotating shaft 302 is fixedly connected to the camera mounting seat 303, so the rotation of the driven pulley 304 drives the rotating shaft 302 to rotate, thereby rotating the camera mounting seat 303 around the rotating shaft 302. Finally, the camera 900 installed inside the camera mounting seat 303 will adjust its angle in the vertical direction as the camera mounting seat 303 rotates to adapt to the tilt state of the vehicle and ensure that the shooting picture is normal.

[0052] In a specific embodiment of the present application, the first drive member 204 and the second drive member 305 are both configured as stepper motors, which are open-loop control motors that convert electrical pulse signals into angular displacement or linear displacement. Each time a pulse signal is input, the motor rotates a fixed angle, which is called a step angle. By controlling the number, frequency and sequence of pulses, the rotation angle and number of turns of the motor can be accurately controlled. For example: STM20M integrated stepper servo motor. The STM20M integrated stepper servo motor has a volume of only 20mm, integrates a stepper motor, an encoder and a driver, has an internal integrated 17-bit absolute encoder, supports CANOPEN / RS485 bus communication, has a variety of motion control modes and configurable DI / DO functions. STM20M integrates a 17-bit absolute encoder, which can provide extremely high angle feedback accuracy for the first rotating assembly and the second rotating assembly, so that the rotation of the turntable 202 and the rotation of the camera mounting seat 303 can be accurately controlled to meet the demand for precise adjustment of the camera angle.

[0053] Please refer to Figures 1 to 8 In one embodiment of the present application, the swing detection component 400 includes a swing rod 401, which is centrally rotatably connected to the mounting base 100, and a driving gear 402 is fixedly connected to the swing rod 401 along its rotation center. A first sensor 403 electrically connected to the controller 600 is fixedly installed on the mounting base 100 corresponding to the driving gear 402, and a driven gear 404 is fixedly installed on the detection axis of the first sensor 403, and the driven gear 404 is meshed with the driving gear 402. The first sensor 403 is used to detect the rotation angle of the driven gear 404.

[0054] During operation, when the vehicle turns during driving, the swing arm 401 will swing relatively under the action of inertia. When the swing arm 401 swings, it will drive the driving gear 402 fixed thereon to rotate together. Since the driving gear 402 and the driven gear 404 are meshed with each other, the rotation of the driving gear 402 will drive the driven gear 404 to rotate accordingly. The detection shaft of the first sensor 403 is fixedly connected to the driven gear 404, so the rotation angle of the driven gear 404 can be accurately detected by the first sensor 403. The first sensor 403 converts the detected angle information into a processable signal form such as an electrical signal, and transmits it to the controller 600, thereby realizing real-time monitoring and feedback of the swing angle of the swing arm 401.

[0055] In some specific implementations of the present application, the first sensor 403 may be a rotary encoder, a potentiometer angle sensor, a magnetoelectric angle sensor, or the like.

[0056] The rotary encoder converts the angular displacement of the driven gear 404 into an electrical pulse signal through photoelectric conversion or electromagnetic conversion. The rotation angle can be calculated according to the number of pulses and the resolution of the encoder. It has high measurement accuracy and can achieve high-precision angle measurement; it has fast response speed and can track the rotation of the driven gear in real time, and has high reliability.

[0057] The potentiometer angle sensor is based on the principle of potentiometer. When the driven gear drives the rotating shaft of the sensor to rotate, the resistance value of the potentiometer will change. By measuring the change in resistance value, the rotation angle can be obtained. The structure is simple and the cost is low; the output signal is analog and the processing is relatively simple.

[0058] The magnetoelectric angle sensor uses the magnetoelectric effect to determine the rotation angle of the driven gear by detecting the change of the magnetic field. It is usually composed of a magnet and a sensing element. When the driven gear rotates, the magnetic field of the magnet changes, and the sensing element converts the magnetic field change into an electrical signal. It can achieve non-contact measurement, no wear, long life; strong anti-interference ability, can adapt to harsh working environments.

[0059] Please refer to Figures 1 to 8 In one embodiment of the present application, both ends of the swing rod 401 are fixedly connected with tension springs 405, one end of the tension spring 405 away from the swing rod 401 is fixedly connected to the inner wall of the mounting base 100, and a counterweight block 406 is fixedly connected to the swing rod 401 near its two ends.

[0060] During operation, the two ends of the tension spring 405 are respectively connected to the swing rod 401 and the inner wall of the mounting seat 100. When the swing rod 401 swings, the tension spring 405 will be stretched or compressed. The tension spring 405 will generate an elastic force opposite to the swing direction, trying to restore the swing rod 401 to the initial equilibrium position, which plays a role in limiting the swing amplitude and providing a reset force. The counterweight block 406 is fixed on the swing rod 401 near the two ends, and uses its own mass to increase the moment of inertia of the swing rod 401. During the swinging process, due to the existence of the moment of inertia, the change of the swinging speed and direction of the swing rod 401 will become relatively difficult, making the swing more stable, and at the same time, it can also affect the frequency and period of the swing to a certain extent.

[0061] Please refer to Figures 1 to 8 In one embodiment of the present application, the tilt detection component 500 includes a sealing box 501 fixedly mounted on the mounting base 100, the length direction of the sealing box 501 is parallel to the length direction of the vehicle body, the top of the sealing box 501 near its two ends are sealed and fixedly connected with vertical tubes 502 extending upward, and a detection tube 503 is sealed and fixedly connected between the two vertical tubes 502; the interior of the sealing box 501 is filled with liquid fluid, and the two vertical tubes 502 are filled with gaseous fluid, and the interior of the detection tube 503 is sealed and slidably connected with a detection column 504, and a slide groove 505 is centrally opened on the outer side surface of the detection tube 503, and the outer side surface of the detection column 504 passes through the slide groove 505 and is transmission-connected with a second sensor 700 electrically connected to the controller 600, and the second sensor 700 is used to detect the sliding position of the detection column 504 inside the detection tube 503.

[0062] During operation, when the vehicle is traveling on a steep slope and tilts, since the length direction of the sealed box 501 is parallel to the length direction of the vehicle body and the inside is filled with liquid fluid, according to the principle of communicating vessels, the liquid fluid will flow in the sealed box 501 under the action of gravity. For example, when the vehicle goes uphill, the liquid fluid flows to the rear end of the sealed box 501; when going downhill, the liquid fluid flows to the front end of the sealed box 501. The two ends of the sealed box 501 are connected to the detection tube 503 through the vertical tube 502, and the vertical tube 502 is filled with gaseous fluid. The flow of liquid fluid will change the pressure of the gaseous fluid at both ends of the sealed box 501. For example, when the liquid fluid flows to one end, the gaseous fluid at this end is compressed, the pressure increases, and the pressure of the gaseous fluid at the other end decreases. This pressure difference will push the detection column 504 in the detection tube 503 to slide toward the end with less pressure. The outer end of the detection column 504 that passes through the outer chute 505 of the detection tube 503 is transmission-connected to the second sensor 700. The second sensor 700 detects the position of the detection column 504 sliding inside the detection tube 503 in real time, and converts the detected position information into an electrical signal and transmits it to the controller 600. The controller 600 determines the tilt state and tilt degree of the vehicle according to the received signal.

[0063] Please refer to Figures 1 to 8 In one embodiment of the present application, the liquid fluid is configured as mercury, and the gaseous fluid is configured as nitrogen.

[0064] During operation, mercury has the characteristics of high density, good fluidity and obvious influence of gravity. When the vehicle tilts, under the action of gravity, the mercury in the sealed box will flow according to the tilt direction. For example, when the vehicle tilts forward while driving on a slope, the mercury will gather at the front end of the sealed box; when the vehicle tilts backward while driving on a slope, the mercury will gather at the rear end, responding to the tilt state of the vehicle through this flow. Nitrogen, as a gaseous fluid, has compressibility and good pressure transmission performance. When the flow of mercury causes the space at one end of the sealed box 501 to be compressed, the nitrogen at that end is compressed and the pressure increases; the space at the other end increases and the nitrogen pressure decreases. The change in nitrogen pressure will push the detection column in the detection tube 503 to slide toward the end with low pressure, thereby converting the flow of mercury into the displacement of the detection column 504. The sliding displacement of the detection column 504 is detected by the second sensor 700 electrically connected to the controller 600. The second sensor 700 converts the position information of the detection column 504 into an electrical signal and transmits it to the controller 600. The controller 600 analyzes and processes the information to obtain relevant data such as the vehicle's tilt angle, thereby realizing the monitoring of the vehicle's tilt state.

[0065] Please refer to Figures 1 to 8 In one embodiment of the present application, the second sensor 700 includes a brush 701 electrically connected to the controller 600, the brush 701 is installed on the outer surface of the detection column 504 at a position in the middle thereof, the brush 701 passes through the slide groove 505, and a resistor block 702 electrically connected to the controller 600 is fixedly installed on the outside of the detection tube 503 corresponding to the brush 701, the resistor block 702 is conductively connected to the brush 701, and a spring 703 is fixedly connected between the brush 701 and the detection column 504, and the spring 703 pushes the brush 701 to abut against the resistor block 702.

[0066] During operation, when the vehicle tilts, the liquid fluid (mercury) in the tilt detection assembly 500 flows, causing the pressure of the gaseous fluid (nitrogen) to change, thereby pushing the detection column 504 in the detection tube 503 to slide. The sliding of the detection column 504 is an external manifestation of the vehicle's tilt state, and its sliding position is related to the degree of tilt of the vehicle. The brush 701 is installed in the middle of the outer surface of the detection column 504 and is connected to the detection column 504 through a spring 703. The spring 703 pushes the brush 701 to always abut against the resistor block 702. When the detection column 504 slides as the vehicle tilts, the brush 701 will slide synchronously on the resistor block 702. Since the resistance values ​​of different positions of the resistor block 702 are different, the sliding of the brush 701 will change the resistance value between the brush 701 and the resistor block 702. The resistor block 702 and the brush 701 are both electrically connected to the controller 600, and the change in resistance value will cause changes in electrical parameters such as current or voltage in the circuit. By detecting the changes in these electrical parameters, the controller 600 can calculate the sliding position of the detection column 504 according to the pre-set corresponding relationship, and then infer the degree and direction of the vehicle's tilt. Since the sliding of the detection column 504 directly drives the brush 701 to slide on the resistor block 702, there are few intermediate links, so the sensor can quickly respond to changes in the vehicle's tilt state. When the vehicle tilts, the detection column 504 slides immediately, and the brush 701 changes its resistance value synchronously. The controller 600 can quickly receive the changing electrical signal to achieve real-time monitoring of the vehicle's tilt state.

[0067] In a specific embodiment of the present application, the resistor block 702 is made of a material with linear resistance characteristics into a rectangular shape, such as constantan (copper-nickel alloy), which is usually composed of about 55% copper and 45% nickel. Constantan has a low temperature coefficient of resistance, that is, the resistance value changes less at different temperatures, and can maintain relatively stable resistance characteristics over a wide temperature range. Its resistivity is moderate and its linearity is good. In the second sensor 700, it can be ensured that when the brush 701 slides on the resistor block 702, the change in resistance value is in a more accurate linear proportion to the sliding distance, so that the controller 600 can more accurately calculate the sliding position of the detection column 504 and the degree of inclination of the vehicle based on the resistance change.

[0068] It is understandable that in other specific embodiments of the present application, the resistor block 702 can also be made of manganese copper (copper-manganese-nickel alloy), the main components of which include copper, manganese and nickel, and the manganese content is generally around 11%-13%. The outstanding feature of manganese copper is that it has an extremely low temperature coefficient of resistance, and even the effect of temperature on resistance can be ignored within a certain temperature range. At the same time, its linear resistance characteristics are very excellent, and the resistance value follows a strict linear law as the length and cross-sectional area change.

[0069] In one embodiment of the present application, the controller includes a control module and an information processing module, the control module and the information processing module are electrically connected, the control module is electrically controlled and connected to the first driving member 204 and the second driving member 305, the information processing module is electrically connected to the first sensor 403 and the second sensor 700, and the control module is also electrically connected to a signal transceiver, and the signal transceiver is radio-connected to a mobile control terminal.

[0070] During operation, the first sensor 403 is responsible for detecting the rotation angle of the driven gear 404 and converting the swing information of the swing rod 401 into an electrical signal; the second sensor 700 converts the position information of the detection column 504 into an electrical signal through the resistance change caused by the brush 701 sliding on the resistor block 702. The two sensors transmit the collected electrical signals to the information processing module. After receiving the electrical signals from the first sensor 403 and the second sensor 700, the information processing module processes and analyzes these signals. The analog signals transmitted from the first sensor 403 and the second sensor 700 are converted into digital signals, and the signal data are converted into actual swing angle and tilt degree information according to the pre-set algorithm and model.

[0071] The control module is electrically connected to the information processing module and receives the processed swing and tilt information. Based on this information and in combination with a preset control strategy, the control module determines whether it is necessary to adjust the angles of the first rotating assembly 200 and the second rotating assembly 300. If adjustment is required, the control module generates a corresponding control instruction. The control module sends the generated control instruction to the first driving member 204 and the second driving member 305, driving the first rotating assembly 200 to rotate in the horizontal direction and the second rotating assembly 300 to rotate in the vertical direction, thereby driving the camera 900 to adjust to a suitable shooting angle.

[0072] At the same time, the signal transceiver electrically connected to the control module can be connected to the mobile control terminal by radio. The user can send a control instruction to the signal transceiver through the mobile control terminal, and the signal transceiver transmits the instruction to the control module. The control module controls the actions of the first driving member 204 and the second driving member 305 according to the instruction, thereby realizing remote control of the camera angle of the driving recorder. At the same time, the control module can also send the status information of the driving recorder (such as the current camera angle, swing and tilt detection data, etc.) to the mobile control terminal through the signal transceiver for the user to view.

[0073] Through the precise analysis of sensor data by the information processing module and the intelligent decision-making of the control module, the driving recorder can automatically adjust the angle of the camera according to the swing and tilt of the vehicle, realize intelligent shooting angle adjustment, ensure clear and complete pictures in various driving conditions, and improve the effectiveness and reliability of driving records.

[0074] The radio connection between the signal transceiver and the mobile control terminal allows the user to remotely control the camera angle of the dashcam. For example, the user can adjust the camera angle outside the vehicle to check the situation around the vehicle; or during driving, the driver does not need to manually operate the dashcam, but can complete the angle adjustment through the mobile control terminal, which improves the convenience and safety of use.

[0075] The two-way data transmission between the control module and the mobile control terminal enables users to understand the working status of the dashcam and the swing and tilt information of the vehicle in real time. This helps users to find potential problems in time, such as abnormal vehicle driving posture, and also facilitates users to manage and maintain the dashcam. The controller adopts a modular design with separate control module and information processing module, which is convenient for system upgrade and maintenance. If you need to improve the information processing algorithm or add control functions, you only need to upgrade the corresponding module, which reduces the maintenance cost and complexity of the system.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
