Description

Technical Field

[0001] This utility model relates to the field of dashcam technology, and more specifically, to a multi-functional dashcam based on the Internet of Things. Background Technology

[0002] With the rapid development and advancement of technology and the increase in car ownership, dashcams, as important in-vehicle devices, are widely used to record video information during driving. Dashcams not only provide evidence in traffic accidents but also help car owners monitor vehicle status and ensure safety. However, existing dashcams still face some problems in practical use:

[0003] During driving, especially in complex road conditions or off-road conditions, the vibration of the vehicle will be transmitted to the dashcam, causing the camera footage to shake and become blurry, which seriously affects the recording quality. Existing dashcams usually only have one fixed image stabilization design, which cannot be adjusted according to different driving environments, resulting in poor image stabilization in some situations. Many existing image stabilization designs rely on complex mechanical springs or friction dampers, which are prone to wear and tear, and may lead to a decrease in image stabilization effect or even failure after long-term use. Utility Model Content

[0004] The problem solved by this invention is that when a vehicle is driving under different road conditions, the camera footage will show different levels of blurriness due to the different vibration frequencies of the dashcam.

[0005] To address the aforementioned problems, this utility model provides a multi-functional dash cam based on the Internet of Things (IoT). The multi-functional dash cam is installed in a vehicle and includes: a fixing device, a buffer device, and a recording device. The fixing device is fixed to the roof of the vehicle; the buffer device is connected to the fixing device to mitigate vibrations generated during vehicle operation; the recording device is movably connected to the fixing device via the buffer device to record the entire vehicle operation process. The buffer device includes a housing, a cylinder, and a regulating valve. The housing is movably connected to the cylinder, and the cylinder is equipped with an oil guide pipe for oil flow. The regulating valve is located on the oil guide pipe to control the oil flow rate inside the pipe, thereby generating different damping forces in the cylinder to adapt to different road conditions.

[0006] The technical effects achieved by adopting this solution are as follows: In existing technologies, vehicle dashcams are equipped with springs to mitigate vibrations during vehicle operation, which slightly improves the image clarity of the dashcam camera footage. However, when the vehicle is traveling on bumpy roads with inclines, the springs have a limited impact on the camera's image. This application effectively mitigates vibrations generated during vehicle operation, ensuring stable operation of the recording device. The buffer device controls the oil flow through a regulating valve, causing the cylinder to generate different damping forces, thereby adapting to different road conditions and ensuring the clarity of the recorded image.

[0007] Furthermore, the buffer device also includes a connecting rod that passes through and moves within the cylinder, and is subjected to damping.

[0008] The technical effect achieved by adopting this technical solution is that the connecting rod moves inside the cylinder and is subjected to damping, which enhances the vibration reduction effect of the buffer device and ensures that the shooting device can remain stable under various driving conditions.

[0009] Furthermore, the connecting rod includes a baffle plate, which is disposed inside the cylinder and fixed to the connecting rod.

[0010] The technical effects achieved by adopting this technical solution are as follows: the presence of the baffle allows the connecting rod to separate the oil in the cylinder during movement, forming two chambers, increasing the oil flow path, improving the damping effect, and further enhancing the vibration reduction performance.

[0011] Furthermore, the cylinder includes a first chamber and a second chamber, which are separated by a baffle plate, and the capacity of the first chamber and the second chamber is changed by the position of the baffle plate; wherein, the first chamber and the second chamber are connected by an oil guide pipe.

[0012] The technical effects achieved by adopting this technical solution are as follows: the two cavities formed by the baffle plate change their respective capacities when the baffle plate moves, which allows the oil to flow in the oil guide pipe, enhances the damping effect, and improves the stability of the system.

[0013] Furthermore, the regulating valve includes a guide element, which is disposed in the oil guide pipe and is movably connected to the inside of the oil guide pipe to control the flow of oil inside the oil guide pipe.

[0014] The technical effects achieved by adopting this technical solution are as follows: the guide can precisely control the flow of oil in the oil pipe, thereby achieving fine adjustment of the damping force and ensuring that the system can improve the best vibration reduction effect under different road conditions.

[0015] Furthermore, the regulating valve also includes: a control component, which is connected to a guide component, controls the guide component to rotate inside the oil guide pipe, and controls the flow rate of the oil inside the oil guide pipe; wherein, the control component has a position one and a position two. When the control component is fixed in position one, the oil inside the oil guide pipe flows rapidly, and the cylinder damping force is reduced; when the control component is fixed in position two, the oil inside the oil guide pipe flows slowly, and the cylinder damping force is increased.

[0016] The technical effects achieved by adopting this solution are as follows: the control component controls the oil flow speed by changing the rotation angle of the guide component, thus achieving dynamic adjustment of the damping force. Users can select the appropriate damping mode according to different driving environments to optimize shooting results.

[0017] Furthermore, the dashcam includes a connecting device disposed between the buffer device and the recording device. The connecting device is equipped with multiple springs to provide a restoring force to the recording device and to limit excessive swinging of the recording device.

[0018] The technical effects achieved by adopting this technical solution are as follows: multiple springs in the connecting device provide the restoring force of the shooting device, allowing it to quickly return to its initial position after the vibration ends, and limiting excessive swinging, thus ensuring the stability of the captured image.

[0019] Furthermore, the fixing device includes a connecting rod, which is detachably fixed to the top of the vehicle, and the end of the connecting rod is provided with a ball head.

[0020] The technical benefits of adopting this solution include: the detachable connecting rod facilitates installation and disassembly, making maintenance and replacement easier for users; and the ball joint design allows for flexible angle adjustment of the fixing device to meet different shooting needs.

[0021] Furthermore, the fixing device also includes a rotating component, which has a space inside for accommodating the ball head, and the rotating component is rotatably connected to the ball head.

[0022] The technical effects achieved by adopting this technical solution are as follows: the rotating part and the ball head rotating connection design allow the fixing device to rotate freely within a certain range, improving the flexibility of the shooting device angle adjustment and adapting to more shooting scenarios.

[0023] Furthermore, the rotating part has an annular groove inside to prevent the ball head from dislodging.

[0024] The technical effects achieved by adopting this technical solution are as follows: The design of the annular groove effectively prevents the ball head from coming out during severe vibration, improves the reliability and safety of the system, and ensures that the shooting device can work stably under various complex road conditions.

[0025] In summary, the various technical solutions described above in this application can have one or more of the following advantages or beneficial effects: i) Through the coordinated work of the cylinder, connecting rod, and regulating valve, vibrations generated during vehicle operation are effectively mitigated. This design ensures that the recording device remains stable under various road conditions, guaranteeing clear and shake-free recording footage. ii) The regulating valve can dynamically adjust the oil flow rate according to different driving environments, thereby changing the damping force. Users can select the appropriate damping mode (such as flat road or off-road) according to actual needs to optimize the recording effect. iii) Multiple springs in the connecting device not only provide the restoring force of the recording device but also limit its excessive swing, ensuring that the recording device quickly returns to its initial position and remains stable after vibration ends. iv) The fixing device adopts a ball joint and rotating component design, allowing the recording device to rotate freely within its range of motion, improving the flexibility of angle adjustment and adapting to more shooting scenarios. v) The detachable design of the connecting rod makes the dashcam easy to install and remove, facilitating user maintenance or replacement. In addition, the modular design simplifies the maintenance process. Attached Figure Description

Detailed Implementation

[0035] The purpose of this invention is to provide a multi-functional dashcam based on the Internet of Things, which can keep the dashcam stable when the vehicle is driving under different road conditions, and avoid the effect of shaking and blurring in the footage captured by the camera.

[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0037] Figure 3 A schematic diagram of the structure for stretching the buffer device; Figure 6 This is a schematic diagram of the structure for compressing a buffer device.

[0038] See Figures 1 to 7 This utility model provides a multi-functional vehicle dashcam based on the Internet of Things. The multi-functional vehicle dashcam is installed in a car and includes: a fixing device 1, a buffer device 2, and a recording device 3. The fixing device 1 is fixed to the top of the car. The buffer device 2 is connected to the fixing device 1 and is used to mitigate the vibration generated during the operation of the car. The recording device 3 is movably connected to the fixing device 1 through the buffer device 2 and is used to record the entire process of the car's operation. The buffer device 2 includes a housing, a cylinder 21, and a regulating valve 22. The housing 26 is movably connected to the cylinder 21. The cylinder 21 is provided with an oil guide pipe 211 for oil flow. The regulating valve 22 is provided on the oil guide pipe 211 to control the oil flow rate inside the oil guide pipe 211, so that the cylinder 21 generates different damping forces to adapt to different road conditions.

[0039] Specifically, the mounting device 1 installs the dashcam in the car's interior ceiling; the recording device 3 is suspended inside the windshield to record all information during the car's driving process; the buffer device 2, positioned between the mounting device 1 and the recording device 3, reduces bumps or vibrations during the car's movement, thus providing vibration damping and ensuring the recording device 3 remains relatively stable, improving the recording quality. The buffer device 2 includes a housing 26, a cylinder 21, a regulating valve 22, and an oil guide pipe 211. The outer diameter of the cylinder 21 is smaller than the inner diameter of the housing 26, and when the buffer device 2 is compressed, the cylinder 21 overlaps with the housing 26. The cylinder 21 is filled with oil, and the oil guide pipe 211 is located on the inner wall of the cylinder 21 for oil flow. The regulating valve 22 controls the oil flow rate inside the oil guide pipe 211, generating different damping forces within the cylinder 21. This ensures that the recording device 3 remains relatively stable under different road conditions, guaranteeing clear footage.

[0040] Furthermore, the resistance generated by the flow of oil in narrow channels is used to absorb vibrational energy. The oil has a high viscosity, enabling it to provide a stable damping effect over a wide temperature range.

[0041] Furthermore, the oil inside cylinder 21 can be made of gas. The compression and release of the gas within the sealed cavity provides a damping effect. The compressibility of the gas allows it to respond quickly to vibrations, but the damping effect is significantly affected by temperature.

[0042] Furthermore, the side of the shooting device 3 away from the car windshield is equipped with a display screen 31 for the user to view.

[0043] See Figure 2 , Figure 3 , Figure 5 and Figure 6 The buffer device 2 also includes a connecting rod 23, which passes through the cylinder 21 and moves within the cylinder 21, and is subjected to damping.

[0044] Specifically, the buffer device 2 also includes a connecting rod 23, which passes through the cylinder 21 and moves up and down inside the cylinder 21, contacting the oil inside the cylinder 21 and receiving a damping effect.

[0045] See Figure 2 , Figure 3 , Figure 5 and Figure 6 The connecting rod 23 includes a baffle 231, which is disposed inside the cylinder 21 and fixed to the connecting rod 23.

[0046] Specifically, a baffle plate 231 is provided on the connecting rod 23. When the connecting rod 23 moves up and down, the baffle plate 231 squeezes the oil into the oil guide pipe 211, thereby improving the vibration damping performance. The connecting rod 23 and the outer shell 26 are fixed on the buffer device 2. The outer shell 26 is movably connected to the cylinder 21, that is, the connecting rod 23 passes through the cylinder 21 and moves up and down, and the baffle plate 231 moves up and down inside the cylinder 21. Figure 3 During the process, the buffer device 2 is stretched, the cylinder 21 does not overlap with the outer shell 26, and the baffle 231 is located in the middle of the cylinder 21; Figure 6 In the middle, the buffer device 2 compresses, the cylinder 21 overlaps with the outer shell 26, and the baffle 231 is located at the bottom of the cylinder 21, squeezing the oil inside the cylinder 21.

[0047] See Figure 2 , Figure 3 , Figure 5 and Figure 6 The cylinder 21 includes a first chamber 24 and a second chamber 25, which are separated by a baffle 231. The capacity of the first chamber 24 and the second chamber 25 is changed by the position of the baffle 231. The first chamber 24 and the second chamber 25 are connected by an oil guide pipe 211.

[0048] Specifically, the cylinder 21 is divided into upper and lower chambers, separated by a baffle plate 231. The first chamber 24 is the upper chamber, and the second chamber 25 is the lower chamber. The capacity of the first chamber 24 and the second chamber 25 is determined by the vertical movement of the baffle plate 231. The first chamber 24 and the second chamber 25 are connected by an oil guide pipe 211. The connecting rod 23 moves up and down, causing the baffle plate 231 to move up and down, squeezing the oil inside the second chamber 25 into the oil guide pipe 211, and then discharging it into the first chamber 24.

[0049] See Figure 3 and Figure 4 The regulating valve 22 includes a guide 221, which is disposed in the oil guide pipe 211 and is movably connected to the inside of the oil guide pipe 211 to control the flow of oil inside the oil guide pipe 211.

[0050] Specifically, the guide 221 is installed inside the oil guide pipe 211 and has the same internal diameter as the oil guide pipe 211. It can be rotated at a certain angle to control the oil flow rate inside the oil guide pipe 211.

[0051] See Figure 3 and Figure 4The regulating valve 22 also includes a control component 222, which is connected to the guide component 221. The control component 222 controls the rotation of the guide component 221 inside the oil guide pipe 211 and controls the flow rate of the oil inside the oil guide pipe 211. The control component 222 has a position one and a position two. When the control component 222 is fixed in position one, the oil inside the oil guide pipe 211 flows rapidly, and the damping force of the cylinder 21 decreases. When the control component 222 is fixed in position two, the oil inside the oil guide pipe 211 flows slowly, and the damping force of the cylinder 21 increases.

[0052] Specifically, the control component 222 is located on the side wall of the cylinder 21 and connected to the guide component 221 inside the oil guide pipe 211, controlling the rotation angle of the guide component 221. The control component 222 has two positions: position one corresponds to a relatively flat ordinary road surface, and position two corresponds to a relatively bumpy dirt road (such as a rugged mountain road). When the control component 222 rotates to position one, the guide component 221 allows the oil inside the guide pipe to flow quickly, reducing flow resistance. The damping force of the cylinder 21 decreases, requiring a lower damping force to stabilize the shooting device 3 in response to low-frequency, small-amplitude vibrations. When the control component 222 rotates to position two, the guide component 221 slows down the flow speed of the oil inside the guide pipe, increasing the damping force of the cylinder 21 to suppress high-frequency, large-amplitude vibrations. A higher damping force is required to stabilize the camera.

[0053] Furthermore, the rotational position of the control element 222 can be increased as needed.

[0054] Furthermore, the control unit 222 can be remotely controlled by an installed device. Vehicle vibration is monitored in real time by onboard sensors, the embedded microcontroller analyzes the data and sends out control commands, which drive a micro stepper motor to adjust the control unit 222. The photoelectric encoder provides closed-loop feedback to guide the rotation angle of the guide 221 to ensure accuracy and dynamically optimizes the damping force, so that the camera device 3 automatically switches the rotation position of the control unit 222 under different road conditions.

[0055] See Figure 1 and Figure 2 The dashcam includes a connecting device 4, which is located between the buffer device 2 and the shooting device 3. The connecting device 4 is equipped with multiple springs 41 to provide a restoring force for the shooting device 3 and to limit the excessive swinging of the shooting device 3.

[0056] Specifically, four disc springs 41 are provided at the connection between the connecting device 4 and the shooting device 3 to provide the shooting device 3 with a restoring force and to limit the left and right swing of the shooting device 3.

[0057] See Figure 1 and Figure 2 The fixing device 1 includes a connecting rod 11, which is detachably fixed to the top of the car, and the end of the connecting rod 11 is provided with a ball head 111.

[0058] The fixing device 1 also includes a rotating member 12, which has a space inside for accommodating the ball head 111, and the rotating member 12 is rotatably connected to the ball head 111.

[0059] Specifically, one end of the connecting rod 11 is detachably installed on the top of the car, and the other end is a ball head 111, which is fixed inside the rotating part 12 and rotatably connected to the rotating part 12 for multi-angle shooting by the shooting device 3.

[0060] See Figure 1 and Figure 2 The rotating part 12 has an annular groove inside to prevent the ball head 111 from dislodging.

[0061] Specifically, the inner edge of the rotating part 12 is provided with an annular groove to prevent vibration during vehicle operation and to allow the ball head 111 to disengage from the rotating part 12.

[0062] The multi-functional dashcam achieves vibration reduction through the synergistic action of its mechanical structure. The fixing device 1 is connected to the vehicle body via a ball joint 111 and a rotating component 12. The buffer device 2 contains a housing-enclosed cylinder 21, which is divided into two chambers. A connecting rod 23 passes through the cylinder 21 and fixes a baffle 231. The baffle changes the volume of the first chamber 24 and the second chamber 25 with vibration displacement, forcing oil to flow between the two chambers via the oil guide pipe 211. The regulating valve 22 changes the oil flow rate inside the oil guide pipe 211 via a guide component 221, controlling the oil flow rate to adjust the flow resistance and create a dynamically changing damping force. The spring in the connecting device 4 absorbs vibration energy through elastic deformation and simultaneously constrains the displacement amplitude of the recording device 3. In this process, the viscous resistance of the oil and the elastic response of the spring work together to counteract the transmission of external vibration to the recording device 3.

[0063] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
