Description
Technical Field
[0001] The utility model belongs to the technical field of driving recorders, and particularly relates to a heat dissipation structure for driving recorders. Background Art
[0002] In recent years, with the continued development of the economy and the improvement of people's living standards, cars have become an important means of transportation for many families, and the number of cars owned has increased rapidly. However, this has also led to increasingly prominent road safety issues. According to relevant Chinese research reports, the number of traffic accidents and fatalities resulting from traffic accidents each year remains high. Against this backdrop, dashcams have garnered widespread attention as a key tool for improving driving safety. Dashcams are devices designed to capture and store video and audio information while a vehicle is in motion. They record real-time video and audio, as well as information such as the vehicle's speed, location, and time, similar to an aircraft's "black box." Their main functions and advantages include preserving accident evidence, recording road conditions, preventing fraudulent activity, monitoring driver behavior, and providing entertainment and sharing.
[0003] The dashcam will continue to work while the vehicle is driving, constantly recording images and audio materials, and processing and storing data. This process will generate a lot of heat. If the heat cannot be dissipated in time, the internal temperature of the device will increase. In a high temperature environment, the performance of electronic components will be affected, and may even cause failures or damage, thereby affecting the stable operation of the dashcam. Therefore, heat dissipation is a key factor in ensuring the long-term and reliable operation of the dashcam. However, the heat dissipation holes of traditional dashcams are usually opened on the side facing the car's windshield. During the heat dissipation process, the heat will diffuse toward the car's windshield, resulting in a temperature difference between the inside and outside of the car at the windshield. Fog will appear on the windshield, blocking the driver's line of sight and affecting the safety of car driving. For this reason, the present application proposes a heat dissipation structure for a dashcam. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the purpose of this utility model is to provide a heat dissipation structure for a driving recorder, aiming to solve the technical problem in the existing technology that during the heat dissipation process of the driving recorder, heat will diffuse toward the windshield of the car, causing a temperature difference between the inside and outside of the car at the windshield, resulting in fogging on the windshield, blocking the driver's vision, and affecting the safety of car driving.

[0013] Beneficial effects
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] The utility model starts the fan in the exhaust hood by setting a fan, generates negative pressure in the air guide groove, and the hot air generated in the interior of the driving recorder body due to continuous work enters the air guide groove from the ring plate, and then enters the exhaust hood and is discharged from the exhaust slot, while the outside air enters from the top of the driving recorder body through the air intake slot on the air intake hood, thereby forming an air circulation between the inside and outside of the driving recorder body, realizing efficient heat dissipation of the driving recorder body, and because the air intake hood is arranged on the top of the driving recorder body and the ring plate is embedded in the bottom of the driving recorder body, during the process of air circulation and heat dissipation inside and outside the driving recorder body, the air flow inside the driving recorder body is from top to bottom, which can avoid dust accumulation inside the driving recorder body.
[0016] The first dust-shielding net arranged in the exhaust slot and the air inlet slot can block external dust and mosquitoes from entering the dash cam body as much as possible.

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] This embodiment provides a heat dissipation structure for a driving recorder, and its structural diagram is as follows: Figures 1-6 As shown, it is applied to the dashcam body 1, including a heat dissipation frame 2 mounted on the dashcam body 1, with an air guide groove 7 provided on the inner wall of the heat dissipation frame 2, and the air guide groove 7 is connected to the internal space of the dashcam body 1. Specifically, a ring plate 8 embedded in the dashcam body 1 is provided at the bottom of the heat dissipation frame 2, and the air guide groove 7 is connected to the internal space of the dashcam body 1 through the ring plate 8. An exhaust hood 3 is provided on the heat dissipation frame 2, which is connected to the air guide groove 7. The exhaust hood 3 is arranged on the top of the heat dissipation frame 2, and an exhaust notch 5 is provided on the exhaust hood 3 facing the side away from the lens of the dashcam body 1. A fan 11 is installed in the exhaust hood 3, and the fan 11 is located below the first dust screen 10. When the fan 11 in the exhaust hood 3 is started, a negative pressure is generated in the air guide groove 7. The hot air generated by the continuous operation of the dashcam body 1 enters the air guide groove 7 from the ring plate 8, and then enters the exhaust hood 3 and is discharged from the exhaust notch 5. The heat dissipation of the driving recorder body 1 is achieved to prevent the internal components of the driving recorder body 1 from being damaged by overheating due to long-term operation. In addition, the exhaust slots 5 are distributed toward the side away from the lens of the driving recorder body 1. After the driving recorder body 1 is assembled on the windshield of the car, the exhaust slots 5 are distributed away from the windshield of the car. Therefore, the hot air flow discharged from the exhaust slots 5 can be prevented from blowing toward the windshield, thereby avoiding the phenomenon of fogging of the windshield due to the temperature difference between the inside and outside of the car, which affects the driver's vision.
[0028] In a further embodiment, an air intake hood 4 is provided on the top of the driving recorder body 1, and the air intake hood 4 is communicated with the internal space of the driving recorder body 1. An air intake slot 9 is provided on the air intake hood 4 facing the lens side of the driving recorder body 1. After the hot air inside the driving recorder body 1 is discharged through the air guide groove 7 and the exhaust hood 3, the external air enters from the top of the driving recorder body 1 through the air intake slot 9 on the air intake hood 4, forming an air flow circulation between the inside and outside of the driving recorder body 1, thereby realizing efficient heat dissipation of the driving recorder body 1.
[0029] In a further embodiment, the exhaust slot 5 and the air intake slot 9 are both equipped with a first dust-proof net 10, which can block external dust and mosquitoes from entering the driving recorder body 1 as much as possible. Since the air intake cover 4 is arranged on the top of the driving recorder body 1, the ring plate 8 is embedded in the bottom of the driving recorder body 1. During the process of air circulation and heat dissipation inside and outside the driving recorder body 1, the air flow inside the driving recorder body 1 is from top to bottom, which can avoid dust accumulation inside the driving recorder body 1.
[0030] Furthermore, a pair of second dust-shielding nets 12 are provided in the air guide groove 7 at the bottom of the heat dissipation frame 2, and the pair of second dust-shielding nets 12 are respectively located at the two ends of the ring plate 8. A bottom cover plate 6 embedded in the air guide groove 7 is provided on the bottom wall of the heat dissipation frame 2. Part of the dust entering the driving recorder body 1 enters the air guide groove 7 under the top-down airflow circulation inside the driving recorder body 1, and is blocked in the air guide groove 7 at the bottom of the heat dissipation frame 2 by the pair of second dust-shielding nets 12. By opening the bottom cover plate 6, this part of the dust can be cleaned.
[0031] In this embodiment, one side of the bottom cover plate 6 is hinged to the heat dissipation frame 2, and a second iron ear plate 14 is provided on the other side of the bottom cover plate 6. A first ear plate 13 that can be aligned and fitted with the second ear plate 14 is provided on the side wall of the heat dissipation frame 2. A magnetic block 15 for magnetically attracting the second ear plate 14 is fixedly penetrated on the first ear plate 13, and a groove 16 is provided on the side of the first ear plate 13. Through this structural method, the opening and closing of the bottom cover plate 6 can be facilitated.
[0032] Working principle: When in use, the driving recorder body 1 is mounted on the front windshield of the car. By starting the fan 11 in the exhaust hood 3, a negative pressure is generated in the air guide groove 7. The hot air generated by the continuous work inside the driving recorder body 1 enters the air guide groove 7 from the ring plate 8, and then enters the exhaust hood 3 and is discharged from the exhaust slot 5. The external air enters from the top of the driving recorder body 1 through the air intake slot 9 on the air intake hood 4. Thus, an air circulation is formed between the inside and outside of the driving recorder body 1, thereby achieving efficient heat dissipation of the driving recorder body 1. Moreover, since the air intake hood 4 is arranged on the top of the driving recorder body 1, the ring plate 8 is embedded in the conduction from the bottom of the driving recorder body 1. Therefore, during the process of air circulation and heat dissipation inside and outside the driving recorder body 1, the airflow inside the driving recorder body 1 is from top to bottom, which can avoid dust accumulation inside the driving recorder body 1. Furthermore, the first dust-proof net 10 provided in the exhaust slot 5 and the air inlet slot 9 blocks external dust and mosquitoes from entering the dash cam body 1 as much as possible. Part of the dust entering the dash cam body 1 enters the air guide groove 7 under the upward-downward airflow circulation inside the dash cam body 1, and is blocked in the air guide groove 7 at the bottom of the heat dissipation frame 2 by a pair of second dust-proof nets 12. By opening the bottom cover 6, this part of the dust can be cleaned to achieve the purpose of efficient dust prevention. Furthermore, since the exhaust slot 5 is distributed toward the side away from the lens of the dash cam body 1, after the dash cam body 1 is assembled, the exhaust slot 5 is distributed back to the windshield of the car. Thus, the hot air flow discharged from the exhaust slot 5 can be prevented from blowing toward the windshield, thereby preventing the windshield from fogging due to the temperature difference between the inside and outside of the car, affecting the driver's vision.
