Embodiment Construction

[0072] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0073] figure 1A door lock device 10 according to an embodiment of the present invention is shown. The door lock device 10 is installed inside the door (not shown) of the vehicle, and is used to close the door relative to the vehicle body. In the closed state, the door lock device 10 can be switched to an unlocked state in which the door can be opened and a locked state in which the door cannot be opened. . In this embodiment, the overall weight reduction is achieved by pivotally supporting the external opening lever 65 on the resin-made protective block 25 .

[0074] like figure 2 and image 3 As shown, the housing 11 includes a housing main body 14 having an L-shape in plan view, a protective block 25 and a cover member 39 attached to the housing main body 14 .

[0075] The housing main body 14 is made of resin, and includes a first arrangement portion 15 arrang...

Abstract

The invention provides a door lock device which is light in weight. The door lock device comprises a spring key mechanism (43) having a shifting fork (44) capable of rotating to engage with or disconnect from a striker (1) and a jaw rod (48) capable of clamping and limiting the shifting fork to maintain the engagement state of the striker and the shifting fork; a locking mechanism (53) being switched through an unlocking operation to an unlocking position where the spring key mechanism (43) can be operated and through a locking operation to a locking position where the spring key mechanism cannot be operated; an opening mechanism (64) having an opening rod (65) which transmits an operation of a door handle to the locking mechanism (53) and being capable of releasing the engagement of the spring key mechanism and the striker when the locking mechanism is located in the unlocking position; and a protection block (25) having a fixing plate (38) used for pivot bearing of the shifting fork of the spring key mechanism. The protection block is provided with a shaft part (33) which can perform rotatable pivot bearing of the opening rod. The protection block is made of resin, while the fixing plate is made of metal.

Description

technical field [0001] The present invention relates to a door lock device. Background technique [0002] The door lock device is arranged so as to be located on an outer end surface opposite to the hinge connection part inside the door of the vehicle. When the door is closed, the door lock device engages with a striker provided on the vehicle body side to hold the door so that it cannot be opened with respect to the vehicle body. [0003] The door lock device includes a latch mechanism capable of engaging or disengaging with a striker disposed on the vehicle body. The operation of the door handle arranged on the inside and outside of the door is transmitted through the opening mechanism, and the operation force thereof is further transmitted to the latch mechanism through the lock mechanism. The lock mechanism can be switched to an unlocked position where the engagement of the striker can be released and a locked position where the engagement of the striker cannot be rele...
