Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing device for an automobile hood.

Various types of opening/closing devices for automobile hoods have been known in the past, and in recent years, automobile hoods of this type have been classified into either one of front-opening and rear-opening.

In this case, the decision as to whether to adopt a front-opening model or a rear-opening model is made mainly from the viewpoint of serviceability. There was a problem.

The present invention has been made in view of such problems, and includes:
To provide an opening/closing device for an automobile hood that can be opened either forward or backward as needed, and furthermore, the entire hood can be removed from the vehicle body as needed.

Therefore, in the first embodiment of the present invention, a hood rotation shaft is provided that extends one length in the front and back directions of the hood, and this hood rotation shaft is used as a striker of the lock mechanism, and the lock mechanism is used only as the original lock mechanism. However, when the front unlocking cable is used as a bearing mechanism for the rotating shaft and the front unlocking cable is installed between the two locking mechanisms at the rear of the vehicle body, the front lock is released. Opening is possible, reverse 1
When you unlock the front side by operating the rear unlocking cable, you can open the rear door, and then operate both the rear unlocking cables to lock the front and rear doors. It is characterized by being bent so that the hood can be removed from the vehicle body by releasing it.

Hereinafter, the present invention will be explained in more detail based on the illustrated embodiments.

As shown in FIG. 1, a front body 1 of an automobile equipped with an engine includes a front side frame 2 that supports a front grill, a rear side frame 3 such as a cowl panel that partitions the engine mounting area and the passenger compartment. The front and rear frames 2 and 3 are connected together in the front-rear direction, and the left and right side frames 4 and 5 form a front suspension housing in the middle.

The left and right side frames 4 and 5 are provided with 1 in the left and right direction on the inside of the upper part of the connection portion with the front side and rear side frames 2 and 3, respectively.
In this case, a pair of front and rear locking devices 6, 6', γ having a structure known per se are arranged opposite to each other.

γ′ and fix it, and lock the front pair of locking devices 6°6.
'1 This is a rear opening unlocking knob 8 that can be operated inside the vehicle.
(A pair of unlocking cables 9, 9' having a well-known double cable structure connected to each other are guided forward along the inner wall 1 of one side frame 4, and one unlocking cable 9 is connected to the left side.) The locking device 61 and the other unlocking case 9 are connected to a cross member 2a forming a part of the eye 1 frame 2.
After inserting the inside, connect the locking devices 6' on the right side respectively, and pulling and operating the rear opening unlocking operation knob 8. From this, the front side locking devices 6 and 6' can be unlocked at the same time. It is so that it can be unlocked.

In addition, the pair of locking devices 7 and 7' on the rear side are connected to a pair of front-opening unlocking knobs 101 that can be operated inside the vehicle interior, similar to the rear-opening unlocking knob 8. Unlocking cables 11, 11' having a double cable structure of
are connected to each other, and by pulling the front opening release operation knob 10, the rear side locking device 7. 1 so that one γ' can be unlocked at the same time.
It's straining.

FIG. 2 1 As shown, the front, B12a and rear 12b of the bonnet 12 that covers the upper surface of the front body 1
The inner wall 1 of the bonnet 12 is connected to the striker shafts 13 and 14, which are the rotational axes of the bonnet 12, in the left-right direction of the vehicle body, respectively, and to the lower surface of the bonnet 12 and the pair of support brackets t-15, 15, 16 degrees. are supported at appropriate intervals.

The striker shaft 13 on the front side becomes a rotating shaft with its both ends locked and held by the locking devices 6, 6', and when the bonnet 12 is opened backwards, as shown in the left half of Fig. 2. When 1, the front part l 2 a is this axis of rotation 1
3, and turn it inward so as not to interfere with the front frame 2, as shown by arrow a.

Therefore, the locking devices 6, 6' serve as bearings for the striker shaft 13 once locked.

As shown in FIG. 2, the locking device 61 on the left side of 1 is attached, and the outer cable 9cl holds the inner cable 9a of the unlocking cable 9 from the wire clamp 9bl.
By pulling the latch 6b against the lock lever 6a, the striker shaft 13 that is locked in the lock groove 6d of the base 6c can be unlocked. Using the striker shaft 14 on the rear side as a rotation axis, the bonnet 12 is rotated once as shown by the arrow in FIG. 2 so that the bonnet 12 can be opened rearward.

The striker shaft 14 on the rear side is supported by a support bracket 161 facing diagonally rearward with the bonnet 12 closed, as shown in the right half of FIG.
As described above, with the striker shaft 14 locked in the lock groove Id of the base γC by the latch 7b held locked by the locking lever γa, the bonnet 12 is moved forward so that it can be opened forward. Arrow C at the rear
As shown in , the design 3b+ of the cowl panel 3s forming a part of the rear side frame 3 is made to fit into the design 3b+.

Note that 17 is a weather strip for preventing rainwater from entering.

Also, as described above, the striker shaft 14 can be unlocked by pulling the inner cable 11a of the unlocking cable 11. 1 strain and 0).

As mentioned above, there are a pair of locking devices 6, 6' at the front and rear of the front body 1, one on each side. , 7' are arranged, and the left and right striker shafts 13 and 14 are provided in the front and rear parts on the bonnet 12 side, and the striker shafts 13 and 14 are also used as rotating shafts. By operating the operating knob 8 to unlock the front side, you can rub the bonnet 12 so that it can be opened backwards, and if you want to open it forward, operate the unlocking operation knob 10 for front opening. By pressing and unlocking the rear side,
I strained it once so that it could be opened in the front.

Further, the entire bonnet 12 can be removed from the front body 1 by unlocking the front and rear parts of the bonnet 12 by simultaneously operating the rear opening and front opening unlocking operation knobs 8 and 10.

As is clear from the above explanation, the present invention supports one striker shaft, which also serves as a rotating shaft, in the left and right direction on the front and rear sides of an automobile hood such as a bonnet, and each striker shaft (with respect to this , when the striker shaft comes down from above, a pair of locking devices are placed on the left and right sides of the front and rear of the vehicle that lock it and release it by pulling the unlocking cable. The present invention provides an opening/closing device for an automobile hood characterized by the following characteristics.

According to the present invention, the rear opening, front opening, and front opening of the automobile hood can be completely removed as needed, so the serviceability of the vehicle can be improved, and the striker and rotating Since the shaft, the locking device, and the bearing device are respectively used, it is possible to obtain the advantage that the structure can be simplified.
