In the technical solution of the utility model, by placing different model modules on different circuit boards, the two circuit boards are stacked to reduce the area of ​​the circuit board, thereby reducing the volume of the device; at the same time, the functional modules of different signals are arranged on different circuit boards to reduce the signal interference between different functional modules.

[0004] Existing GNSS positioning terminals do not have rainproof and water drainage structures. When used outdoors, water easily enters the device connection gap or heat dissipation window. Once water enters, the rainwater cannot be discharged in time, which will affect the service life of the device. At the same time, the above-cited patent documents do not propose relevant solutions to solve the above problems.

[0005] Therefore, in order to solve the above problems, a GNSS positioning terminal with water discharge function is proposed. Utility Model Content

[0017] Compared with the prior art, the GNSS positioning terminal with water discharge function is equipped with a rain cover, a rain sensor, a rain baffle and a leakage hole. The rain sensor can monitor in real time whether it is raining outside. If rain is detected, the servo motor will work to drive the rain baffle to rotate. The rain baffle can be rotated to a primary rain protection mode slanting downward or a completely closed absolute rain protection mode, which has a better rain protection effect. If water enters the functional seat, the rainwater will fall into the water guide groove formed between the ladder seat and the functional seat under the action of gravity, and then be discharged from the device through the leakage hole to achieve water discharge and prevent rainwater from affecting the service life of the device.

[0018] Compared with the existing technology, the circuit board of the GNSS positioning terminal with water discharge function is placed in a semiconductor refrigeration frame, which can effectively dissipate the heat of the working circuit board and prevent the functional component group from overheating and damage. The semiconductor refrigeration frame forms an elastic buffer structure through spring buffer columns and ladder bases, which can effectively reduce vibration and impact force, reduce damage to the internal functional components of the device due to collision or falling, and is safer to use.
