Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a front lid lock device for a vehicle.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, there is a front lid provided as a foldable panel section at a lower portion of a front panel for inspecting internal equipment housed in a lower portion of a cab (see Japanese Utility Model Laid-Open No. 2-25376). As shown in FIG. 4, this front lid is attached to the lower part of the front panel 2 of the cab 1 of the vehicle through a hinge, and by operating a lid opener provided in the cabin of the cab 1, the lid opener is operated. The lock device connected to the wire with a wire is released and opened.

For example, in a tilt-type cab-over vehicle, when a passenger performs an opening operation of the front lid 3 while the cab 1 is tilted, the front lid 3 is opened while accelerating and the peripheral parts such as the bumper 4 are opened. If you accidentally open the vehicle and accidentally open it while driving, you may obstruct the forward field of view.In order to prevent these, a second lock mechanism separate from the first lock mechanism that is released by the lid opener is used. There is one provided. In this case, the front lid 3 is half-opened by the unlocking operation by the lid opener, and then the second locking mechanism is released to completely open the front lid 3.

Therefore, even if the first lock mechanism is released by the lid opener, the front lid 3 is locked by the second lock mechanism, so that the front lid 3 is accelerated even in the tilted state and the traveling state. It has a safe structure that does not open.

[0005]

[Problems to be solved by the device]

 By the way, the conventional second lock mechanism is provided with, for example, an engaging portion on one of the front panel and the front lid, and a lever-type hook on the other, and by engaging the hook with the engaging portion, the front lid is locked. 3 is locked to the front panel 2 side.

However, conventionally, when releasing the second lock mechanism, the hook inside the front lid is operated from the outside of the lid to release the lock, but the hook cannot be seen from the outside, and the hook is felt by hand. I'm looking for and are unlocking. Therefore, there is a problem that it takes a long time to release the second lock mechanism and the hands are soiled. The present invention has been made in view of the above circumstances, and an object thereof is to facilitate the operation of releasing the second lock of the front lid.

[0007]

[Means for Solving the Problems]

 Therefore, according to the present invention, the front lid rotatably supported on the front surface of the cab is provided with the first locking means operated by the lid opener provided in the cab chamber and the second locking means provided inside the front lid. A front lid lock device for a vehicle configured to be locked in two stages by one locking means, wherein the unlocking operation portion of the second locking means is exposed to the outer surface of the front lid.

[0008]

[Action]

 According to this structure, since the unlocking operation portion of the second locking means is visible and it is not necessary to put a hand inside the lid, the unlocking operation of the second locking means is easy and the hand You will be able to do it without getting dirty.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3, an unlocking operation portion 12 of a second locking means, which will be described later, is provided at an appropriate position on the outer surface of the front lid 11. As shown in FIG. 2, the unlocking operation portion 12 includes a cylindrical guide member 13 having a flange portion 13a, and a stepped columnar slide member that is slidably inserted into the guide member 13. 14 and the flange portion 13a of the guide member 13 is fitted and fixed to the front lid 11. As shown in FIG. 1, the inner end surface of the slide member 14 on the inside of the rit is in contact with the side surface of a hook 16 rotatably provided on the inner surface of the front lid 11 by a hinge 15.

The second locking means is composed of the hook 16 and an engaging member 17 having a shape as shown in FIG. 3, which is fixed to the front panel side (not shown). The engaging member 17 has an engaging groove 17a formed near the tip thereof, with which the tip of the hook 16 is engaged. Further, the hook 16 is elastically biased to the hinge 15 in the locking direction (counterclockwise direction in FIG. 1) by a coil spring or the like.

Next, the operation of this embodiment will be described. After operating the lid opener in the vehicle compartment to unlock the first locking means to bring the front lid 11 into the half-opened state, the slide member 14 of the unlocking operation portion 12 of the second locking means is moved to the front lid 11. Operate from the outside and slide it toward the inside of the lid as shown by the chain double-dashed line in FIG. As a result, the hook 16 is pushed as shown by the chain double-dashed line in FIG. 2, and pivots clockwise in FIG. 1 against the elastic force of the coil spring with the hinge 15 as a fulcrum. By the pivoting operation of the hook 16, the tip of the hook 16 is disengaged from the engaging groove 17a of the engaging member 17, and the lock of the second locking means is released.

If the hand is released from the slide member 14 after unlocking, the hook 16 automatically rotates counterclockwise in FIG. 1 by the elastic force of the coil spring, and the slide member 14 is released before unlocking. Return to the original position. Further, when the front lid 11 is closed, if the front lid 11 is simply closed, the tip of the hook 16 automatically penetrates through the engaging groove 17a of the engaging member 17 and engages with each other to be locked.

According to this structure, since the unlocking operation of the second locking means can be performed at a position visible from the outside of the front lid 11, the unlocking operation becomes extremely easy. In addition, it is not necessary to put the hand inside the front lid 11 to perform the unlocking operation by groping, so that the hand is not soiled.

[0014]

[Effect of device]

 As described above, according to the present invention, since the unlocking operation portion of the second locking means is provided so as to be exposed on the outer surface of the front lid, the unlocking operation of the second locking means is extremely easy. In addition, it is not necessary to perform the unlocking operation by groping inside the front lid, and the hands are not soiled by the unlocking operation.
