Description

Technical Field

[0001] The invention belongs to the technical field of 4G law enforcement instruments, and specifically relates to a cooling device for a 4G law enforcement instrument under a long-term high-temperature working state. Background Art

[0002] The 4G law enforcement recorder is a law enforcement recording device that can record videos and upload them to a monitoring platform via a 4G network.

[0003] In the utility model patent with authorization announcement number CN206413108U, a 4G law enforcement recorder is disclosed, including a shell, a battery compartment is arranged in the shell, and the battery compartment is sealed by a battery cover. It is characterized in that an intercom microphone and a recording microphone are respectively arranged on the left and right sides of the top of the front side of the shell, and an infrared lamp and a laser lamp are arranged above the intercom microphone and the recording microphone, and the laser lamp is located on the outside of the infrared lamp. A brightness sensor, a lighting lamp and a camera are also arranged on the front side of the shell, and the lighting lamp is located above the camera.

[0004] However, the existing 4G law enforcement cameras need to be in standby mode for a long time, so their temperature will be too high, which will affect their normal use. In addition, during the law enforcement process, a slightly violent movement will cause the recorder to fall off the body, which is not stable enough. Therefore, it is necessary to design a cooling device for 4G law enforcement cameras that work under high temperature for a long time. Summary of the invention

Then, air intake mesh covers are set on both sides of the cooling shell, and an air outlet is set at the bottom. A rotating shaft driven by a motor is set on the inner side of the air outlet, and the rotating shaft is provided with fan blades. This can drive the circulation of air in the cooling shell, and can take away the heat absorbed by the heat-conducting seat and the heat dissipation fins, thereby achieving the purpose of dissipating the heat of the law enforcement instrument body, so that it can continue to work in a high temperature environment.

[0017] Secondly, a vibration mechanism is arranged on the inner side of the air intake grille. The swing pin in the vibration mechanism is fixed on the rotating shaft and rotates with the rotating shaft. The swing pin will periodically hit the top pin, so that the top pin will apply the impact force to the striker pin through the linkage block. Then the striker pin will hit the air intake grille after passing through the hollow shell.
