Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a vehicle door cylinder lock.

(Prior art) As a device of this kind, a cylinder lock is provided with a rotor that rotates left and right from a neutral position, and a lock cam that pivotally supports the operating rod of the door lock on the rotor and a switch provided in the operating circuit of the door lock are opened and closed. It is known that a cylinder lock is provided with a switch cam so that a cylinder lock can be rotated from a neutral position to a locking position or an unlocking position of a door lock.

(Problem to be solved by the invention) In this case, various mutual relationships between the lock cam and the switch cam provided on the rotor have been proposed, but the assembly is complicated, and
Since two cams are arranged in a stack on the rotor, the operation is not smooth, and most of them have two switches arranged around the cylinder lock to detect the rotation of the switch cam in the locking or unlocking direction. The problem was that the system configuration became expensive. The present invention aims to improve such defects.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be described with reference to an embodiment.A cylinder lock 2 mounted on a vehicle door is equipped with a rotor 3 that rotates left and right from a neutral position. A lock cam 6 and a door lock operating circuit 7 are provided, and a door lock operating lever 5 is attached to the rotor 3.
A switch cam 9 for opening and closing the switch 8 provided at the cylinder lock 2 is provided so that the cylinder lock 2 can be rotated from the neutral position to the locking position or the unlocking position of the door lock.
The switch cam 9 is formed to be a sliding type having an operator 8a arranged adjacent to the rotor 3 and tilted from a neutral OFF position to an ON position on both sides. 8a is formed into a cam plate having a pair of actuating pieces 9a, 9a sandwiched at a distance, and the lock cam 6 is engaged with the rotor 3 with a predetermined rotation angle. shall be.

(Function) The present invention uses the above-mentioned means to provide the cylinder lock 2.
When the rotor 3 of the key is rotated in one direction, the door lock is unlocked, and when the rotor 3 is rotated in the other direction, the door lock is locked.
The switch cam 9 is engaged with the rotor 3 with a predetermined play rotation angle, and the switch cam 9, which is integrated with the rotor 3, is sandwiched between its actuating pieces 9a, 9a and the operating element 8a of the switch 8 with a play gap. The initial turning force of the rotor 3 is reduced to allow smooth operation.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 indicates a door handle, and a rotor 3 of a cylinder lock 2 attached to the front surface of the door handle 1 is protruded from the back surface of the door handle 1. , the rotor 3
always returns to the neutral position by return spring 4,
It is provided so that it can be rotated left and right from the neutral position by means of a key, and a door lock operating rod 5 is attached to the terminal of the key.
A lock cam 6 that pivotally supports the door lock, and a switch cam 9 that opens and closes a switch 8 provided in the door lock operating circuit 7.
and are provided by polymerization. And switch 8
is attached to the back side of the door handle 1 adjacent to the cylinder lock 2, and the switch 8 is formed into a sliding type having operating elements 8a that automatically return to the neutral OFF position and tilt to the ON position on both sides, The switch cam 9 is formed into a cam plate having a pair of actuating pieces 9a, 9a sandwiching the operator 8a with a clearance, and the square shaft of the rotor 3 is inserted into the square hole of the cam plate and locked. Furthermore, the lock cam 6 has a pair of protrusions 3a, 3a provided in the shaft hole of the lock cam 6, which protrude in the diametrical direction of the rotor 3 so as to engage the rotor 3 at a predetermined rotation angle. Approximately 30 mm to the engagers 6a, 6a
The rotor 3 is provided so as to be engaged with the lock cam 6 at an angle of 40°C, and after the engagement, the rotor 3 is provided to further rotate with the lock cam 6 to an angle of about 40°C. The door lock is unlocked by the rotation, and the operating pieces 9a, 9 of the switch cam 9
At the same time, the operator 8a of the switch 8 is also tilted to the on position.

(Effect of the invention) As described above, according to the present invention, the switch 8 provided in the door lock operating circuit 7 is formed into a sliding type having operating elements 8a that tilt from the neutral on position to the on positions on both sides. At the same time, the switch cam 9 provided on the rotor 3 of the cylinder lock 2 has a pair of operating pieces 9 that sandwich the operating element 8a with a gap between them.
Since it is formed on a cam plate having a and 9a, it is easy to assemble the switch 8 and the switch cam 9, and the initial rotation of the rotor 3 when the switch is activated is made light, and it also supports the operating rod 5 of the door lock. Since the lock cam 6 is engaged with the rotor 3 with a predetermined free rotation angle, it is easy to assemble the lock cam 6, and the lock cam 6 is left in the lock position so that the rotor 3
This has the effect of making the initial rotation easier.
