Automobile microelectronic control navigation circuit board mechanism

Abstract

The invention discloses and relates to the technical field of circuit boards, in particular to an automobile microelectronic control navigation circuit board mechanism. The mechanism includes circuitboard bodies, the circuit board body is of a curved plate structure which is bent back and forth, wherein upper protection plates are arranged above the circuit board bodies, a plurality of groups ofcircuit board bodies are arranged, bottom protection plates are arranged at the lower ends of the circuit board bodies, rubber buffer pads are fixedly arranged at the bottoms of the bottom protectionplates, side protection plates are arranged on the side surfaces of the circuit board bodies, heat dissipation holes are formed in the surfaces of the side protection plates, and the upper ends of theside protection plates are fixedly welded on the bottom surfaces of the upper protection plates. The circuit board body is of a curved plate structure bent back and forth, the number of surface bearing circuits is large, and reasonable utilization is achieved; according to the invention, the circuit board body is vertically installed, so that heat dissipation gaps are increased; fixing structuresare arranged on the upper portion and the lower portion of the circuit board body, fixing is stable, resistors and wiring boards which can move and adapt to a certain range are installed on the leftside and the right side of the circuit board body, damage caused by resonance at the wiring positions is avoided, and protectiveness is high.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to an automotive microelectronic control navigation circuit board mechanism. Background technique [0002] Circuit boards are divided into three major categories: single-panel, double-panel, and multi-layer circuit boards according to the number of layers. [0003] It is single panel at first, and on the most basic PCB, parts are concentrated on one side, and wires are concentrated on the other side. Because wires only appear on one side, this PCB is called a single-sided circuit board. Single-sided panels are usually easy to manufacture and low in cost, but the disadvantage is that they cannot be applied to too complicated products. [0004] Double-sided panels are an extension of single-sided panels. When single-layer wiring cannot meet the needs of electronic products, double-sided panels must be used. There are copper clad and traces on both sides, and the lines betwee...

AI Technical Summary

Problems solved by technology

[0007] 1. In the prior art, the single-sided board is often a rectangular plate-shaped structure, and the circuit structure carried on the surface is less;

[0008] 2. In the existing technology, the bottom of the single panel is often directly installed on the body, and the heat dissipation of the bottom is poor, which affects the service life;

[0009] 3. In the prior art, when the single panel is installed, especially in the car navigation system, it often has bumpy resonance phenomenon, and the wire body is easy to fall off and loose, which affects the use
