Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automobile hood locking device for locking the hood of an automobile.

(Prior Art) For example, as disclosed in Japanese Utility Model Application Publication No. 53-98412, a conventional automobile hood lock device engages with the hood on a vertical base plate fixed to the vehicle body to lock the hood. Various rotating members such as a latch lever that locks in the closed state and a locking lever that restricts the rotation of this latch lever are pivotally connected, and grease is injected into the sliding parts between these rotating members and the board. This allows each rotating member to rotate smoothly.

(Problems to be Solved by the Invention) Automobile hood lock devices are usually installed in the front part of the car body, which is easily exposed to the outside air. Raindrops, dust, etc. that enter the surface of the hood lock device wash away the oil on the surface of the hood lock device, or the paint peels off, causing early rusting. The grease injected into the sliding parts between the board and the board may be washed away by wind and rain, or dust or dirt contained in the outside air may adhere to the grease and fall in clumps, causing the grease to become eroded. There is a problem that grease tends to dissipate from sliding parts, so-called grease runs out quickly.

If this kind of grease runs out, problems such as the operation of each rotating member become unsmooth and rust formation occur, so it is necessary to replenish new grease as soon as possible. It is often difficult to inject grease into the sliding parts between each rotating member and the board, etc. after it has been assembled to the vehicle body, and even if it is possible to do so, the work is often complicated. .

SUMMARY OF THE INVENTION An object of the present invention is to provide an automobile hood lock device that solves these problems.

(Means for Solving the Problems) The present invention has a substrate fixed to either the vehicle body side or the hood side, and the hood is closed by engaging the substrate with the other of the vehicle body side or the hood side. In the automotive hood lock device, the outer surface of the board is covered with a protective cover, and the outer surface of the board is covered with a protective cover, and the outer surface of the board is covered with a protective cover. The present invention is characterized in that the cover is provided with an oil injection hole that penetrates the base plate and communicates with a gap between the base plate and an arbitrary rotating member.

(Function) According to the present invention, the protective cover protects the entire hood lock device, especially its substrate, from raindrops and dust flying from the radiator grille, and also supplies lubricating oil such as grease through the oil injection hole. It can be easily injected into the gap between the substrate and any rotating member at any time.

From this state, insert your fingers under the hood and By pushing up the tip of the portion 14 and rotating the secondary latch lever 10 in the unlocking direction,
The hook portion 13 is disengaged from the hook engaging portion 22a so that the hood can be opened.

The above configuration is almost the same as the conventional configuration,
The present invention is characterized by adding the following configuration to these configurations.

That is, in this embodiment, as clearly shown in FIG. 1, the front surface of the substrate 1 has a front surface shape that is approximately the same shape and size as the front surface shape of the substrate 1, and has appropriate elasticity. A protective cover 23 made of hard synthetic resin has engaging hooks 24 extending rearward from both ends of the protective cover 23 to engage both edges of the board 1, and a step protruding from the rear surface of the lower center of the protective cover 23. By press-fitting the small diameter portion 25a at the tip of the attached shaft 25 into the fitting hole 26 drilled in the substrate 1, the substrate 1
Therefore, the secondary latch lever 10 is attached with a gap d ₁ (see FIG. 4) in the front and back direction that is large enough to rotate.

Reference numeral 23a denotes a spring accommodating portion that protrudes forward from a portion near one side of the protective cover 23, in which a tension spring 12 for biasing the secondary latch lever 10 can be accommodated.

A refueling cylinder 28 is connected to the rear surface of the protective cover 23 and protrudes toward the rear, the tip of which passes through a through hole 27 drilled below the shaft 4 in the base plate 1. At the center of 28, there is provided an oil injection hole 29 which doubles as an oil reservoir and has both ends open to the front surface of the protective cover 23 and a rear end opened to the gap _d2 between the base plate 1 and the locking lever 3.

The front end of the oil injection hole 29 can be closed by a lid 30 that can be opened and closed and is connected to the protective cover 23 via a flexible piece 30a.

A hook piece 30b facing backward is connected to the tip of the lid 30, and this hook piece 30b is attached to the protective cover 2.
By engaging the engagement hole 31 drilled below the oil injection hole 29 in FIG. 3, the lid 30 can be latched in the closed state as shown by the solid line in FIG. By removing the piece 30b from the engagement hole 31, the lid 30 can be opened, as shown in phantom lines in FIG.

Since this embodiment has the above-described configuration, the protective cover 23 protects the entire hood lock device, especially the substrate 1 thereof, from raindrops and dust flying from the radiator grille, and protects the hood lock device, especially the substrate 1, from the oil adhering to the substrate 1. This prevents the paint from being washed away by wind and rain or from peeling off the paint.

Also, as shown by imaginary lines in FIG. 4, open the lid 30 and insert the injection nozzle 32a of the grease injector 32.
By inserting the grease 33 into the oil injection hole 29 and spouting the grease 33, the inside of the oil injection hole 29 and the gap d ₂ can be easily filled with the grease 33 at any time, and the grease 33 accumulated in the gap d ₂ can be easily filled with the grease 33. This spreads around the shaft 4 as the locking lever 3 rotates, allowing the locking lever 3 to rotate smoothly and preventing rust.

Even if the grease 33 in the gap d ₂ disappears, the grease 33 accumulated in the oil injection hole 29 leaks into the gap d ₂ , so that the grease 33 in the gap d ₂ remains for a long time.
can be supplied, and the grease 33 has good durability.

Furthermore, in this embodiment, the oil injection hole 29
A lid 30 is provided on the front surface of the oil injection hole 29, and the lid 30 is closed except when injecting the grease 33, so that raindrops, dust, etc. do not enter the oil injection hole 29.

The procedure for opening and closing the hood of this embodiment and the actions of each member at that time are the same as those of the known ones,
Since this is a matter self-evident to those skilled in the art, detailed explanation thereof will be omitted.

(Modification) In the above-mentioned embodiment, the protective cover 23 includes:
Although the oil injection hole 29 communicating with the gap between the base plate 1 and the locking lever 3 is provided, instead of this or in addition to this structure, a rotating member other than the locking lever 3, for example, the primary latch lever 6 may be connected to the oil injection hole 29. Board 1
An oil injection hole communicating with the gap between the protective cover 23 and the protective cover 23 may be provided.

Moreover, when the oil injection hole 29 is made small in diameter, the lid 30 does not need to be particularly provided.

Conversely, the oil injection hole 29 may have a large diameter or a liquid reservoir may be provided in the middle of the oil injection hole 29 to increase its function as an oil reservoir.

(Effects of the Invention) As is clear from the above, according to the present invention, the following effects can be achieved.

(b) The protective cover protects the entire hood lock device, especially its circuit board, from raindrops and dust flying from the radiator grill, and prevents oil adhering to the circuit board from being washed away by wind and rain or the paint peeling off. Therefore, the durability of the food lock device can be improved.

(b) Since grease can be easily injected even after the entire hood lock device has been assembled, problems that arise when injecting grease in the middle of the assembly process, such as problems caused by injected grease, can be avoided. As a result, rotating members and pivots may be lifted or moved to the side, causing misalignment, which may cause problems when assembling other parts, or the injected grease may adhere to the conveyor line, causing it to become dirty. It is possible to solve problems such as problems that occur.

(c) The grease that accumulates in the oil injection hole is unlikely to be washed away by wind and rain, and there is little risk of dust, etc. adhering to it, and the grease retains well.

(d) If the grease runs out, it can be easily replenished.
