Inductively controlled circuit board fixing structure of automobile model

Abstract

The invention relates to the technical field of circuit board installation, in particular to an inductively controlled circuit board fixing structure of an automobile model. A locking device comprisesa fixing shaft and a pressure plate. Straight rods are disposed in through holes and are in sliding connection with the through holes. One end of the straight rod is fixedly connected with the top ofa positioning sleeve. The other end of the straight rod passes through the corresponding through hole from bottom to top and then is fixedly connected with the pressure plate. The outer side wall ofthe fixing shaft is provided with shaft external threads. The top of a spacer sleeve is fixedly connected with the bottom of the positioning sleeve. A plurality of thin plates are uniformly distributed in the inner cavity of a outer fixing sleeve. The top of the thin plate is hinged to the outer fixing sleeve. The bottom of the thin plate is inclined downwards and is directed to the axis directionof the fixing shaft. A support spring is fixed to the bottom of the thin plate. The end of the support spring is pressed against the inner side wall of the outer fixing sleeve. The inductively controlled circuit board fixing structure can improve the assembly and disassembly efficiency of the circuit board, and the components of the circuit board fixing structure can be used repeatedly.

Description

technical field [0001] The invention relates to the technical field of circuit board installation, in particular to a circuit board fixing structure of an induction-controlled car model. Background technique [0002] Remote control model car is not a toy, it is actually a reduced version of a real car; some remote control model cars are actually the epitome of a real sports car, but we are not sitting in the car to control; in Europe, America, Japan and even Southeast Asian countries, remote control model car competitions It's a sport, it's a sport, it's a high-tech hobby. [0003] The circuit board inside the remote control model car is used to receive external control signals and issue instructions to control the walking of the remote control model car. The circuit board is generally installed in the car by welding or screwed with bolts and screwed to lock and fix it in the remote control model car; the circuit board fixing method of the welding type is fast and conveni...

AI Technical Summary

Problems solved by technology

The circuit board is generally installed in the car by welding or screwed with bolts and screwed to lock and fix it in the remote control model car; the circuit board fixing method of the welding type is fast and convenient to fix and install the circuit board, but the welding structure is irreversible. When the plate is removed, the welded structure needs to be destroyed; therefore, it is inconvenient to maintain; and the bolt-fixed form requires multiple bolts to be locked and fixed, and the locking efficiency of the bolt-fixed is low; when the bolts are connected, it is easy to slip teeth ; also invalidates the structure
