Protection device of vehicle cylinder lock

Abstract

A protector of a cylinder lock for a vehicle in which a shutter plate, which is capable of operation between a closed position where an insertion hole corresponding to a keyhole of the cylinder lock is closed and an open position where the insertion hole is open, is housed in a casing, and in which a magnet lock that allows the operation of the shutter plate from the closed position to the open position during the engagement of the magnet key into the engagement concavity is disposed in the casing, wherein the magnet lock (25A) is formed separately from the shutter plate (24A) and is provided with a rotor (26A) in which the engagement concavity (27) is provided, the rotor (26A) being connected to the shutter plate (24A) via a link mechanism (44). This increases the degree of freedom in the selection of the material and manufacturing method of the shutter plate and enables the shutter plate to be formed from a high-strength material.

Description

technical field [0001] The present invention relates to a protection device for a cylinder lock for a vehicle, comprising: a casing having an insertion hole corresponding to a keyhole of the cylinder lock; It moves between the locked position of closing the above insertion hole and the open position of opening the above insertion hole, and is received inside the above housing; the magnetic lock has a fitting recess that can be inserted and pulled out to fit the magnetic key, according to The housing is provided in such a manner that when the magnetic key is fitted into the fitting recess, the opening and closing plate is allowed to move from the locked position to the opened position. Background technique [0002] In the past, the above-mentioned device has been disclosed in, for example, JP-A-2000-104426. [0003] However, in the above-mentioned conventional devices, the rotating member provided with the magnetic lock and the opening and closing plate are integrally formed...

AI Technical Summary

Problems solved by technology

In addition, due to its complex shape, the rotating part forming part of the magnetic lock is generally formed by die casting, and the strength of the molded product cannot be said to be high, so it is difficult to obtain high strength for the opening and closing plate.

In addition, since the rotating member in the cylinder lock must be formed of a non-magnetic material, the degree of freedom in selecting the material of the opening and closing plate is limited.
