Electronic speed controller device with multilayer shielding structure

Abstract

The invention discloses an electronic speed controller device with a multilayer shielding structure. The electronic speed controller device comprises a drive module and a control module, wherein the drive module comprises a drive module shielding shell and a drive module end cover; the drive module shielding shell is provided with a first opening, an assembling vessel and a second opening which are mutually communicated; the drive module end cover is arranged at the second opening in a covering way; a drive part shielding shell is convexly arranged on the inner wall of the assembling vessel, and divides the assembling vessel into at least first shielding cavity; the control module comprises a control module end cover and a control module shielding shell which are mutually connected; the control module shielding shell is nested in the first shielding cavity; the control module end cover is arranged at the first opening in the covering way. The drive module shielding shell, the control module shielding shell and the drive part shielding shell form a three-layer shielding structure arranged in a laminating way inside and outside, and a control signal leaked during work can be completely shielded in the three-layer shielding structure, so that the influence on antenna intermodulation is reduced maximally, and thus the intermodulation level of an antenna product is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an electric control device with a multi-layer shielding structure. Background technique [0002] In the field of mobile communication, the signal coverage area and distance of the base station antenna are affected by the beam direction of the antenna, and the adjustment of the beam direction can usually be done by adjusting the mechanical downtilt angle of the antenna, but this method requires manual adjustment and is inconvenient to maintain; and in recent years The operation convenience of the electric adjustment method is favored by technicians, and the installation of the electric adjustment downtilt device on the antenna brings great convenience to the maintenance of the device. These days, such devices are often referred to as RET units, or "remote electric tuning" devices. The structure of the existing electric adjustment device is usually to install the control ci...

AI Technical Summary

Problems solved by technology

Due to the poor airtightness caused by the quality of the shielding material used in the shell, the processing accuracy of the shell and the end cover, etc., the shielding effect of the shell will be reduced, causing leakage of the control signal or affecting the transmission stability of the signal, and further affecting the antenna interaction. Influenced by the modulation, the intermodulation level of the antenna product is reduced
