A type of overheat-proof dashcam

Abstract

This utility model discloses an overheat-resistant dash cam, relating to the field of dash cam technology. It includes a connecting base, an adjustment component on one side of the connecting base, and a heat dissipation mechanism on the other side for cooling the dash cam. The heat dissipation mechanism includes a mounting plate with mounting holes through the four corners of its top. Through the adjustment component and heat dissipation mechanism, during use, the heat sink frame and sealing strip are first installed on the outer casing via the mounting plate and mounting holes. When the internal components of the dash cam operate, the heat generated is transferred to the outer casing components, contacting the heat-conducting plate. The heat-conducting plate then conducts the heat to the heat spreader and the heat sink. The heat sink undergoes a phase change when its temperature rises, absorbing a large amount of heat, which is further absorbed through the heat dissipation fins. Simultaneously, a fan accelerates airflow and exhausts the heat through a dustproof plate. This device effectively reduces the internal temperature of the dash cam.

Description

Technical Field

[0001] This utility model relates to the field of dashcam technology, specifically to an overheat-resistant dashcam. Background Technology

[0002] Dashcams are a common car accessory. They record events along the way in real time and can also preserve video evidence after a traffic accident, playing an important role in safe driving. Dashcams are installed on the windshield and generate a lot of heat when working continuously. Because the dashcam is enclosed, air circulation is not good, and heat is not easily dissipated, which can easily cause the internal electronic components to age and reduce the lifespan of the dashcam. Especially in summer, the sun shines on the dashcam and generates high temperatures. If it is powered on under these conditions, it can easily cause the internal components to overheat and be damaged.

[0003] Existing dashcams typically employ simple heat dissipation designs, such as adding ventilation holes to the casing or using a metal casing to improve heat dissipation performance. However, these existing solutions have some drawbacks. First, the design of the ventilation holes may be unreasonable, failing to fully utilize airflow for heat dissipation and thus limiting the improvement of heat dissipation effect. Second, although metal casings have good thermal conductivity, their size and heat dissipation area limitations still cannot meet the heat dissipation requirements of high-power dashcams. Therefore, we propose a more convenient and practical dashcam to meet user needs. Utility Model Content

[0004] The purpose of this invention is to provide an overheat-resistant dashcam to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an overheat-proof dash cam, including a connecting base, an adjustment component on one side of the connecting base, and a heat dissipation mechanism on one side of the connecting base for dissipating heat from the dash cam. The heat dissipation mechanism includes a mounting plate, mounting holes are provided through the four corners of the top of the mounting plate, a heat dissipation frame is fixedly connected to the bottom of the mounting plate, a sealing strip is fixedly connected to the outer wall of the heat dissipation frame, and a heat dissipation component is provided inside the heat dissipation frame.

[0006] Furthermore, the adjustment assembly includes a connecting plate, which is connected to a connecting base, and a connecting socket is electrically connected to one side of the connecting plate.

[0007] Furthermore, a rotating rod is rotatably connected to one side of the connecting plate, a fixing bolt is installed at one end of the rotating rod, and a housing is fixedly connected to one end of the rotating rod. A camera is installed on one side of the housing, and a slot is opened on one side of the housing, which is compatible with the mounting plate.

[0008] Furthermore, the mounting plate has slots on both sides of the top, with dustproof plates fixedly connected inside the slots, fans installed on both sides of the bottom of the mounting plate, and heat dissipation fins fixedly connected to the center of the top of the mounting plate.

[0009] Furthermore, the heat dissipation assembly includes a heat spreader plate, a heat sink plate and a heat conduction plate are provided on one side of the heat spreader plate, the heat spreader plate and the heat dissipation frame are connected to each other, and the heat conduction plate is in contact with the outer shell components.

[0010] Furthermore, the heat sink is made of microcapsule phase change material.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This overheat-resistant dashcam, through adjustments to its components and heat dissipation mechanism, works by first installing the heat sink frame and sealing strip onto the outer casing via a mounting plate and mounting holes. When the internal components of the dashcam operate, the heat generated is transferred to the outer casing components, contacting the heat-conducting plate. The heat-conducting plate then conducts the heat to the heat spreader and the heat sink, ensuring even heat distribution. The heat sink undergoes a phase change when its temperature rises, absorbing a large amount of heat, which is further absorbed through its heat dissipation fins. Simultaneously, a fan accelerates airflow and exhausts the heat through a dustproof plate. This device effectively reduces the internal temperature of the dashcam, preventing overheating that could lead to decreased performance, shortened lifespan, or even damage to electronic components. It is highly practical and suitable for widespread adoption.

[0012] Meanwhile, the adjustment components can flexibly adjust the angle of the housing and the camera mounted on it according to the actual usage scenario and needs. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] A dashcam is needed while the car is in motion. The dashcam provided by this utility model is specifically designed for dashcam heat dissipation. When using this device for heat dissipation, ensure that all components are securely connected during installation of the dashcam and its heat dissipation mechanism 8 to prevent components from loosening or falling off due to vibrations during vehicle operation. Before use, check whether the fan 806 of the heat dissipation mechanism 8 is operating normally, and whether components such as the heat dissipation fins 807 and the heat spreader 808 are clean and unblocked to ensure good heat dissipation. The dashcam generates a certain amount of heat when working, so avoid prolonged exposure to direct sunlight or high-temperature environments to prevent affecting the heat dissipation effect and the lifespan of the dashcam.

[0017] like Figures 1-3 As shown, this utility model provides a technical solution: an overheat-proof dash cam, including a connecting base 1, an adjustment component on one side of the connecting base 1, and a heat dissipation mechanism 8 on one side of the connecting base 1 for dissipating heat from the dash cam. The heat dissipation mechanism 8 includes a mounting plate 801, mounting holes 802 are provided through the four corners of the top of the mounting plate 801, a heat dissipation frame 803 is fixedly connected to the bottom of the mounting plate 801, a sealing strip 804 is fixedly connected to the outer wall of the heat dissipation frame 803, and a heat dissipation component is provided inside the heat dissipation frame 803.

[0018] like Figure 2 As shown, the adjustment assembly includes a connecting plate 2, which is connected to the connecting base 1. A connecting socket 3 is electrically connected to one side of the connecting plate 2, and a rotating rod 5 is rotatably connected to one side of the connecting plate 2. A fixing bolt 4 is installed at one end of the rotating rod 5, and a housing 6 is fixedly connected to one end of the rotating rod 5. A camera 7 is installed on one side of the housing 6, and a slot is opened on one side of the housing 6. The slot is compatible with the mounting plate 801.

[0019] It should be noted that during use, the angle of the housing 6 and the camera 7 is first changed by rotating the rotating rod 5 to obtain the desired shooting angle. After adjusting to the appropriate angle, the fixing bolt 4 is tightened to fix the rotating rod 5, thereby locking the angle of the housing 6. Finally, the connecting plate 2 and the connecting base 1 are installed on the fixing piece, and the connecting port 3 provides power and data transmission for the camera 7 and other devices. The adjustment component can flexibly adjust the angle of the housing 6 and the camera 7 installed on it according to the actual use scenario and needs.

[0020] like Figure 3 As shown, the mounting plate 801 has slots on both sides of the top, and a dustproof plate 805 is fixedly connected in the slots. Fans 806 are installed on both sides of the bottom of the mounting plate 801. A heat dissipation fin 807 is fixedly connected to the center of the top of the mounting plate 801. The heat dissipation assembly includes a heat spreader 808. A heat dissipation plate 809 and a heat conduction plate 810 are provided on one side of the heat spreader 808. The heat spreader 808, the heat dissipation plate 809 and the heat dissipation frame 803 are connected. The heat conduction plate 810 is in contact with the outer shell 6 components. The heat dissipation plate 809 is made of microcapsule phase change material.

[0021] It should be noted that during use, the heat sink frame 803 and sealing strip 804 are first installed on the housing 6 through the mounting plate 801 and mounting holes 802. When the internal components of the dashcam are working, the heat generated is transferred to the components on the housing 6 and comes into contact with the heat conduction plate 810. The heat conduction plate 810 conducts the heat to the heat spreader 808 and the heat sink 809. The heat spreader 808 distributes the heat evenly. When the temperature rises, the heat sink 809 undergoes a phase change to absorb a large amount of heat and absorbs heat through the heat dissipation fins 807. At the same time, the fan 806 runs to accelerate airflow and exhausts the heat through the dustproof plate 805. The heat dissipation mechanism 8 is easy to install and disassemble, making it more convenient for production, assembly, and subsequent maintenance and replacement.

[0022] During use, the angles of the housing 6 and camera 7 are first changed by rotating the rotating rod 5 to obtain the desired shooting angle. After adjusting to the appropriate angle, the fixing bolt 4 is tightened to fix the rotating rod 5, thereby locking the angle of the housing 6. Finally, the connecting plate 2 and the connecting base 1 are installed on the fixing component. At the same time, the connecting port 3 provides power and data transmission for the camera 7 and other devices. The heat dissipation frame 803 and the sealing strip 804 are installed on the housing 6 through the mounting plate 801 and the mounting hole 802. When the heat generated by the internal components of the dashcam is transferred to the components of the housing 6, it comes into contact with the heat conduction plate 810. The heat conduction plate 810 conducts the heat to the heat spreader 808 and the heat sink 809. The heat spreader 808 distributes the heat evenly. When the temperature rises, the heat sink 809 undergoes a phase change to absorb a large amount of heat and absorbs heat through the heat dissipation fins 807. At the same time, the fan 806 runs to accelerate the airflow and exhausts the heat through the dustproof plate 805. This device can effectively reduce the internal temperature of the dashcam and prevent the electronic components from degrading, shortening their lifespan, or even being damaged due to overheating.
