Description

Technical Field

[0001] This utility model relates to the field of dashcam technology, and in particular to a dashcam with a heat dissipation structure. Background Technology

[0002] A dashcam is an electronic device used to record images, sounds, and other status information during vehicle operation. It can provide evidence for traffic accidents and also has extended functions such as navigation and driver assistance. During use, dashcams generate heat inside their casing. To cool the internal electrical components, a heat-conducting structure or a miniature fan is installed inside the casing to assist in heat dissipation and improve the device's durability.

[0003] However, in actual use, since the heat-conducting structure and the miniature fan are both installed inside the casing, they are inconvenient to maintain. Moreover, the miniature fan only has the effect of cooling the electrical components, resulting in its limited functionality and significantly reducing the applicability of the dashcam. Therefore, this application proposes a dashcam with a heat-dissipating structure that is easy to maintain and has multiple functions. Utility Model Content

[0004] The purpose of this invention is to address the problems of inconvenient maintenance and limited functionality of built-in heat dissipation structures in the prior art, and to propose a vehicle dashcam with a heat dissipation structure that is easy to maintain and has multiple functions.

Two brackets are fixedly installed at the two ends of the housing that are far apart from each other. A connecting shaft is fixedly installed at the top and bottom of the fan. The end of the connecting shaft that is far away from the fan is rotatably connected to a matching bracket.

[0007] The heat dissipation vents are located at both ends of the housing, and the fan is located on one side of the corresponding heat dissipation vent.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1 , Figure 2 As shown, this utility model proposes a dashcam with a heat dissipation structure, including a housing 1. Heat dissipation vents 7 are provided at both ends of the housing 1 to ensure that heat inside the housing 1 can be discharged outwards through the vents 7. Fans 4 are provided on both sides of the housing 1. Connecting shafts 42 are fixedly installed at the top and bottom of the fans 4. Two brackets 41 are fixedly installed at both ends of the housing 1. The ends of the connecting shafts 42 away from the fans 4 are rotatably connected to the matching brackets 41, ensuring that the fans 4 can be rotated and adjusted. When the fans 4 rotate and face the heat dissipation vents 7, they can deliver cold air into the housing 1, accelerating the efficiency of heat dissipation and improving the cooling effect on the internal electrical components. When the fans 4 rotate and face the passengers, they can blow cold air onto the passengers, thus serving as a cooling device for them and increasing its functionality. The fans 4, as a heat dissipation structure, are installed on the outside of the housing 1 for easy maintenance.

[0032] like Figures 2-3 As shown, in order to facilitate the installation of the dashcam, a rear cover plate 9 is fixedly installed on the outer shell 1, and a suspension bracket 2 is fixedly installed on the rear cover plate 9. A suction cup 3 is threadedly installed on the end of the suspension bracket 2 away from the rear cover plate 9. The suction cup 3 is attached to the windshield of the car to ensure that the suspension bracket 2 can firmly install the outer shell 1 on the windshield of the car. The dashcam can be disassembled by removing the suction cup 3, which improves the convenience of installing and removing the dashcam.

[0033] Furthermore, to facilitate the adjustment of the dashcam's tilt angle, two limiting blocks 91 are fixedly installed on the rear cover plate 9, and a connecting block 21 is fixedly installed on one end of the suspension bracket 2. The connecting block 21 is positioned between the two limiting blocks 91. A locking screw 22 is threaded through both the connecting block 21 and the limiting block 91. A locking nut 23 is threaded onto one end of the locking screw 22. When the locking nut 23 is not in close contact with the matching limiting block 91, the outer casing 1 can be rotated to facilitate the adjustment of the dashcam's tilt angle. When the locking nut 23 is in close contact with the matching limiting block 91, the outer casing 1 can be locked and fixed, improving the stability of the dashcam after the angle is adjusted.

[0034] Secondly, to prevent the dashcam from rotating on its own after the angle is adjusted, several rubber washers 92 are movably sleeved on the locking screw 22. One rubber washer 92 is tightly clamped between the nut of the locking screw 22 and the matching limit block 91, one rubber washer 92 is tightly clamped between the locking nut 23 and the matching limit block 91, and the other two rubber washers 92 are tightly clamped between the connecting block 21 and the matching limit block 91. The rubber washers 92 can increase the friction between the connecting block 21, the nut of the locking screw 22, and the contact end surfaces of the locking nut 23 and the limit block 91, thereby improving the stability of the dashcam after installation.

[0035] like Figure 4 As shown, in order to improve the ease of disassembly and assembly of the suction cup 3, a rotating block 31 is fixedly installed at the bottom of the suction cup 3. A connecting screw 32 is fixedly installed at the end of the rotating block 31 away from the suction cup 3. The threaded end of the connecting screw 32 is inserted into the internal threaded hole drilled on the suspension frame 2 and threadedly connected to it. The threaded connection structure facilitates the disassembly and assembly of the suction cup 3.

[0036] In this embodiment, a display screen 5 and a button 6 are fixedly installed on the outer casing 1. The control boards of the display screen 5 and the button 6 are electrically connected to the circuit board inside the outer casing 1. A camera 8 is fixedly installed on the outer casing 1 and located on one side of the rear cover 9. The camera 8 is electrically connected to the circuit board inside the outer casing 1. The camera 8 can capture images of the scene in front of the car and display the images on the display screen 5. The button 6 is used to conveniently set the dashcam, improving its ease of use. During the use of the dashcam, the fan 4 is rotated and directed towards the heat dissipation vent 7, so that the fan 4 can dissipate heat into the inner casing 1. The delivery of cool air accelerates air circulation within the casing 1, aiding in the expulsion of internal heat and improving the dashcam's heat dissipation. Since fan 4, as a heat dissipation structure, is installed externally on the casing 1, it facilitates maintenance should a malfunction occur, enhancing the ease of maintenance. When fan 4 rotates and faces the passengers, it blows cool air onto those in the driver's seat, thus serving as a cooling device for them. This gives the dashcam's heat dissipation structure both cooling the circuit board and cooling the passengers, increasing its functionality and effectively improving its applicability.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
