Problems solved by technology

[0004] Due to the nature of such a solenoid, it is necessary to continuously energize it during driving (when the shift lever is in a position other than the "P" position), and it is necessary to drive the plunger against the force of the spring, so a large driving force is required. The size of the solenoid may increase, power consumption may increase, or the steering lock and key may become hot due to heat generated by the solenoid

Embodiment approach

[0199] According to the second embodiment described above, it is constituted by the leaf spring 260 having the functions of the first spring 61 and the second spring 62 of the first embodiment in one member. Therefore, instead of three coil springs that are originally required, only one spring is required in the second embodiment, and the number of parts can be reduced, thereby reducing costs.

[0200] In addition, in the second embodiment, the leaf spring 260 can be mounted coaxially with the rotating shaft 244 of the link 240, and the connecting rod 240, the slider 250, the leaf spring 260, and the rotating shaft 244 can be assembled in advance, so that Figure 11B As shown, componentization is realized, so assembly man-hours can be reduced.

Abstract

The invention provides a steering locking device which is miniature, low in power consumption and capable of reducing heating of a solenoid. The steering locking device (1) comprises a connecting rod (40) which prevents a cam shaft (20) to rotate towards a locking position at a limiting position of a withdrawing position of a plunger (31) and allows the cam shaft (20) to rotate towards a locking position at an allowing position of a protruding position of the plunger (31); a sliding block (50) enabling the connecting rod (40) to move between the limiting position and the allowing position according to the rotation of the cam shaft (20); a first spring (61) applying a force to the sliding block (50) so as to enable the connecting rod (40) to be located at the limiting position; and a second spring (62) applying a force to the connecting rod (40) so as to enable the connecting rod (40) to be located at the allowing position. According to the rotation from the locking position to a conduction position of the cam shaft (20), the sliding block (50) utilizes the acting force of the first spring (61) to move, and the connecting rod (40) is enabled to move towards a stop position.

Description

technical field [0001] The invention relates to a steering lock device in which a key cylinder is locked by a key lock mechanism and a key cannot be pulled out. Background technique [0002] The steering locking device of automatic transmission vehicles is equipped with a key interlock device, which is locked by the key when the shift lever is set to reverse gear "R", neutral gear "N" or forward gear "D" other than the park gear "P". The mechanism locks the cylinder without the ability to remove the key. [0003] Usually, this key interlock device uses a solenoid. For example, when the shift lever is in a position other than "P", the solenoid is energized so that the plunger protrudes and engages with the cam of the steering lock device, so that the key cannot be released. The "locked" position turns. In addition, when the energization is released, the plunger returns to the initial plunged position by spring force (see Patent Document 1). [0004] Due to the nature of su...
