no. 1 Embodiment approach

[0040] This embodiment is cited in the above description figure 2 and image 3 The door lock device 100 in. In the door lock device 100 , a water hole 10 penetrating the second storage space B is provided in the casing 1 as a water stop mechanism. The housing 1 includes a first cover 1a and a second cover 1b, and a water passage 10 is formed on the upper side of the housing 1 and is formed in one of the first cover 1a and the second cover 1b. Because it is necessary to combine the door lock device 100 with the lock striker 300 on the side of the vehicle body X, it is necessary to make one end (that is, the latch mechanism 2) on the side of the second accommodation space B toward the edge portion 300a of the door Y (refer to figure 1 ) exposed to install it. In addition, the door lock device 100 is provided inside the door Y, and moisture such as rainwater flows through the inside of the door Y. Therefore, moisture such as rainwater reaches the door lock device 100 inside ...

no. 2 Embodiment approach

[0044] exist Figure 4 Among them, FIG. (a) is a partial front view showing the main part configuration of the door lock device 200 in the second embodiment of the present invention. (b) is a partial plan view of the door lock device 200 . In the door lock device 200 of this embodiment, a V-shaped water stop plate 20 is additionally provided on the water passage hole 10 as a water stop mechanism. The configuration other than this is the same as that of the door lock device 100 of the first embodiment.

[0045] The water stop plate 20 can be provided within a range from the upper surface side of the casing 1 , that is, the end portion of the cover member 6 to a position above the first accommodation space A described above. More specifically, it can be installed close to the upper surface of the casing 1 corresponding to the upper position of the second storage space B. Moisture such as rainwater enters from the gap between the cover member 6 on the second storage space B si...

Abstract

Provided is a door lock device which can positively prevent water from approaching and making contact with electrical components housed in a housing. In the housing 1, a latch mechanism 2 which can holds a vehicle door in a closed state in a vehicle body, a lever mechanism 3 driven by door handles arranged inside / outside the vehicle door, a link mechanism 4 interposed between the lever mechanism 3 and the latch mechanism 2, for switching the position thereof in order to connecting / disconnecting transmission of an operating force from the lever mechanism 3 to the latch mechanism 2, and a mode driving mechanism 5 for switching the position of the link mechanism 4, and secures, in the housing 1, a first housing space A where at least the motor driving mechanism is installed, and a second housing space B where at least the latch mechanism 2 is installed. The door lock device is comprised of a water cutoff means for inhibiting water entering an upper portion of the housing 1 from further entering an upper portion of the first housing space A through an upper portion of the second housing space B.

Description

technical field [0001] The present invention relates to a door lock device for a door of an automobile or the like. More specifically, it relates to a door lock device that can be used for a vehicle door using electrical components such as an automatic door lock. Background technique [0002] As a conventional door lock device, a device including a latch mechanism, a handle mechanism, a link mechanism, a motor drive mechanism, and the like in a housing is known (for example, refer to Patent Document 1). Here, the latch mechanism is a mechanism for switching a vehicle door between a closed support state and an openable state with respect to the vehicle body. The handle mechanism is a part that operates the latch mechanism, and operates by operating a door opening mechanism such as a door handle. The link mechanism and the motor drive mechanism are mechanisms for switching between an unlocked state in which the latch mechanism can operate and a locked state in which it canno...
