DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel vehicular lamp. Specifically, in a vehicle lamp having a communication hole for communicating a lamp chamber with the outside in order to prevent clouding of a lens or a reflection surface, a lid is provided on an outer peripheral wall of two peripheral walls protruding from a lamp body. A new structure in which water is prevented from easily penetrating into the lamp chamber by forming a single-piece part and forming a double-structured ventilation path consisting of two spaces formed between the lid part and the peripheral wall part. It is an object of the present invention to provide a vehicular lamp.

[0002]

2. Description of the Related Art There is a vehicular lamp having a communication hole for communicating a lamp room with the outside in order to prevent clouding of a lens or a reflection surface.

FIG. 18 shows an example a of such a vehicular lamp.

[0004] Reference numeral b denotes a lamp body made of a synthetic resin.
Is formed. "e" denotes a light bulb arranged in the lamp room "d", which is attached to the lamp body "b".

F denotes a communication hole formed in the rear wall of the lamp body b, and a cylindrical communication tube g extends from a peripheral edge of the communication hole f.
Is projected rearward. h is a substantially L-shaped waterproof pipe having a side surface, and one end of the waterproof pipe h is externally connected to the communication pipe g.

In the vehicle lamp a described above, air flows in the lamp chamber d from the waterproof pipe h through the communication hole f, thereby preventing clouding of the lens c and the like. Further, since a waterproof pipe h having a substantially L-shaped side surface is attached to the communication pipe g, water from the outside is exposed to the light chamber d.
Hard to penetrate inside.

However, such a vehicular lamp a has a problem in that the cost is increased because a waterproof pipe h is used separately from the communication pipe g.

In order to solve such a problem, Japanese Utility Model Laid-Open No. 60-84003 discloses a vehicle lamp a 'as shown in FIG.

In the vehicle lamp a ', a communication hole f' is formed in a rear wall of a lamp body b 'made of synthetic resin, and an upper wall i extending rearward from an upper edge of the communication hole f'. When,
Side walls j, j (only one is shown in the figure) extending downward from the left and right side edges of the upper surface wall i and having a front edge continuous with the rear surface of the lamp body b '. Wall i
The lid k connected to the rear edge forms a ventilation path m which communicates with the communication hole f 'and extends vertically and has a lower end l opened.

The lid k is formed integrally with the upper wall i via a thin hinge portion n, and the lid k is moved from a state in which it projects rearward as shown by a two-dot chain line in FIG. This is bent at a substantially right angle at the hinge portion n and is brought into contact with the rear end of the side wall j, j.
It is stuck to.

Accordingly, the lamp chamber d 'defined by the lamp body b' and the lens c 'is provided with the communication hole f' and the ventilation path m.
Is communicated with the outside through

[0012]

By the way, in the above-mentioned vehicular lamp a ', a waterproof pipe h, which is a separate member, is not used as in the vehicular lamp a shown in FIG. k
Is formed integrally with the lamp body b ', the cost can be reduced. For example, when the splashed water enters from the opening at the lower end of the ventilation path m, the infiltrated water reaches the communication hole f'. There is a problem that the light reaches the light room d 'as it is.

[0013] Further, since the lid k has a simple structure in which one space for ventilation is formed by abutting the lid k on the side walls j, j, the lid k and the side walls j, j are connected to each other. (Particularly, if the lid and the side wall are made of synthetic resin, the degree of adhesion between the two members becomes a problem.) Water or the like easily enters the lamp chamber d '. There is a problem of entering.

[0014]

According to the present invention, there is provided a vehicular lamp having a lamp chamber defined between a lens and a lamp body. Is formed in the lamp body, and has the following configurations (a) to (f). (A) The first so that it is located above the communication hole and on the left and right sides
Is provided on the rear surface of the lamp body, and a part of the wall includes a water blocking wall provided below the communication hole. (B) A second peripheral wall surrounding the first peripheral wall is projected from the rear surface of the lamp body, and the second peripheral wall covers the protruding end side of the first peripheral wall. The lid to be positioned is formed integrally. (C) When the lid abuts on the first peripheral wall, a first space is formed between the lamp body, the lid, and the first peripheral wall, and the first space forms a communication hole. It is communicated with the light room through. (D) a second space is formed between the lamp body, the lid, the first peripheral wall, and the second peripheral wall by contacting the lid with the second peripheral wall; (E) The first space communicates with the second space via a first passage formed in a lower portion of the first peripheral wall. (F) a second space formed at a position below the second peripheral wall portion and not facing the opening of the passage;
Through the passage.

[0015]

Therefore, in the vehicle lamp according to the present invention, since the lid is formed integrally with the second peripheral wall, a separate member such as a waterproof pipe is not required, and the lamp body,
A double structure including a first space formed between the first peripheral wall and the lid, and a second space formed between the lamp body, the first and second peripheral walls, and the lid. Forming an airway,
Since the first passage connecting the first space and the second space and the opening of the second passage connecting the second space and the outside are arranged so as not to face each other, the first passage from the outside can be prevented. Water is second
And it is difficult to penetrate the first space through the space.

1 are facing each other on the opposing surfaces.
Are formed. The steps 18 are located slightly forward of the rear ends of the eaves wall 14 and the impermeable walls 15u, 15d.

Reference numeral 19 denotes a lid, which is the upper outer peripheral wall 16u.
Are integrally connected to each other via a thin integral hinge 20 formed at the rear end edge (see FIGS. 7 and 8). The lid 19 has a plate shape slightly larger than a region surrounded by the eaves wall 14, and a large shallow recess 21 is formed on a surface facing the rear wall 9. The recess 21 is the eaves wall 14
The rear end is sized to fit completely.

The tip of the lid 19, that is, the hinge 2
An engagement piece 22 protrudes from a center in the left-right direction of an end opposite to the end connected to the upper peripheral wall 16u at 0.

An elongated hole 23 extending in the left-right direction is formed at a position near the rear end of the lower outer peripheral wall 16d.

The lid 19 is bent at a substantially right angle by the hinge 20, so that the eave wall 14 and the impermeable wall 15u,
5d so that the engaging piece 22 is engaged with the engaging hole 23 of the lower outer peripheral wall 16d.

The rear end of the lid 15d is located in the recess 21 of the lid 19, and the left and right side edges of the lid 19 are left and right outer peripheral walls 16r, 16r.
1 are brought into contact with the steps 18, 18.

Therefore, between the lamp room 5 and the outside of the lamp body 2, the cylindrical portion 13, the rear surface of the rear wall 9, the eaves wall 14
, The impermeable walls 15u and 15d, the outer peripheral wall 16, and the lid 19
A maze-shaped air passage 24 communicated with the communication hole 12 is formed in a portion surrounded by

That is, the air passage 24 is formed in the cylindrical portion 1 of the communication hole 12.
3, an eaves wall 14, water-impervious walls 15 u and 15 d, a first space 24 a defined by a portion 9 a of the rear wall 9 and a lid 19, and an eaves wall 14 and an outer peripheral wall 1.
6 and part 9b of the rear wall 9 divided by these
And a second space 24b defined by the cover 19 and the first space 24a and the second space 24b. The passage 15p is formed between the impermeable walls 15u and 15d. And the second space 24b and the outside are cutout 17
Are communicated through.

In the headlamp 1 for an automobile, the lid 19 is formed integrally with the upper outer peripheral wall 16u, and the lid 19 is provided with the eaves wall 14 and the impermeable walls 15u, 1u.
The air passage 2 having a double structure including a first space 24a formed by covering 5d and a second space 24b formed by abutting the lid 19 on the inner surface of the outer peripheral wall 16.
4, sufficient waterproof measures can be taken.

For example, even if water splashes on the ventilation portions 11 and 11 'due to splashing during running, such water is blocked by the outer peripheral wall 16, particularly the lower outer peripheral wall 16d.

Further, even if there is water that enters the ventilation path 24 through the notch 17 of the outer peripheral wall 16, the notch 17 and the opening of the passage 15p are in a positional relationship such that they do not face each other. It is extremely rare that water enters the first space 24a from above, and even if an attempt is made to enter the first space 24a, the water is blocked by the impermeable wall 15u and the cylindrical portion 13, whereby water reaches the light room 5. It can be prevented from reaching.

Although water generated by splashing or the like often comes from the left and right sides of the lamp, the notch 17 is provided at the center of the lamp (the opening 8 of the light bulb 7) in the ventilation sections 11 and 11 '.
(Closer to the side), so there is an effect that water is hard to enter from this point as well.

Since the lid 19, the eaves wall 14, and the outer peripheral wall 16 are made of synthetic resin, there is a problem in the sealing property between these members.
And the side edge of the lid 19 abuts on the inner surface of the outer peripheral wall 16, and the abutment direction of the lid 19 against the eaves wall 14 and the outer peripheral wall 16 is different. ing.

Therefore, the lid 19 is attached to the eaves wall 14 and the outer peripheral wall 16.
The waterproofness can be improved by making the film sufficiently adhere to the surface. That is, in a configuration in which the inner surface of the lid 19 is simply brought into contact with the protruding end of the eaves wall 14 and the protruding end of the outer peripheral wall 16,
If the amount of rearward projection of the outer wall 16 and the outer wall 16 is not set to the same value with high accuracy, a gap may be formed between the lid 19 and the eaves wall 14 or the outer peripheral wall 16, and water or the like may enter. However, by changing the contact direction of the lid 19 with the eaves wall 14 and the outer peripheral wall 16 as described above, the lid 19 and the eaves are not required to have high molding accuracy. Wall 1
4 and the lid 19 and the outer peripheral portion can be brought into a state of being in close contact with each other.

As described above, the communication between the lamp chamber 5 and the outside of the lamp is established by the maze-shaped ventilation path 24, and only the inflow and outflow of air between the inside of the lamp chamber 5 and the outside is permitted. Thus, even if clouding occurs in the lens 4, the reflector 6, or the like, the clouding is quickly eliminated. Especially,
In the automotive headlamp 1, one vent 11 is located at the upper right and the other vent 11 'is located at the lower left, so that the vent 11' → light room 5 → vent 11 The flow of air is distributed evenly in the light room 5 along the path.

If the cross-sectional area of the passage 15p communicating the first space 24a and the second space 24b of the ventilation path 24 is substantially the same as the cross-sectional area of the communication hole 12, the flow rate in the communication hole 12 can be reduced. Thus, a sufficient flow can be ensured in the lamp room 5.

Further, since the members constituting the ventilation portions 11 and 11 'are all formed integrally with the lamp body 2, the cost can be reduced. The left and right eaves walls 14
The reason why the r, 14l and the left and right outer peripheral walls 16r, 16l are inclined in reverse is to make it possible to remove a mold for forming the concave portion 21 of the lid portion 19.

In the first embodiment, the cylindrical portion 13 of the communication hole 12 is formed in a cylindrical shape. However, like the cylindrical portion 13A shown in FIG. 9, a rectangular cylindrical shape surrounding the rectangular communication hole 12A is formed. May be formed. Further, the impermeable wall 15u is continuously formed so as to extend from the lower end of the left eave wall 14l rightward to just before the right eave wall 14r, and the impermeable wall 15d is connected to the right eave wall 14r.
r so as to extend leftward from the lower end to below the left eaves wall 14l, the first space 24
a and a passage 15p communicating the second space 24b with the second space 24b is formed as shown in FIG.
As shown in the passage 15q, a configuration having an opening facing in the horizontal direction may be adopted. However, in this state, water or the like easily enters the passage 15p through the notch 17 of the outer peripheral wall 16, so that the notch 17 and the opening of the passage 15q need to have a positional relationship that does not face each other. For example, as shown in FIG. 9, the notch 17A may be formed in the lower right part of the outer peripheral wall 16.

In the first embodiment, the lid 19 is formed integrally with the upper outer peripheral wall 16u. However, the present invention is not limited to this, and the lid 19 may be formed in another part of the outer peripheral wall 16. Of course, for example, the lid portion 19 is formed integrally with the right outer peripheral wall 16r to form a laterally open lid structure.

FIGS. 10 to 15 show a second embodiment of the vehicular lamp according to the present invention, in which a dustproof filter is disposed in a first space of a ventilation section and a waterproof wall is provided on an outer peripheral wall. The only difference from the first embodiment is that only the ventilation portion 11A is shown. In addition, this ventilation part 11
Since A is almost the same as that of the ventilation portion 11, the same portions are denoted by the same reference numerals as those of the similar portions in the ventilation portion 11, and the description is omitted. The manner of omitting such description is the same in the third embodiment described later.

Reference numeral 25 denotes a filter for preventing dust and the like in the air from entering the lamp chamber 5, and is formed in a rectangular parallelepiped shape by a soft urethane sponge. The filter 25 is attached to the concave portion 21 of the lid 19 corresponding to the first space 24a of the ventilation portion 24 so that the filter 25 is fitted inside the first space 24a of the ventilation portion 24 except the passage 15p when the lid 19 is closed. It is attached using an adhesive or the like.

Reference numerals 26 and 27 are waterproof walls formed integrally with the outer peripheral wall 16.

The waterproof wall 26 is formed integrally with the left outer wall 161 in such a manner as to be inclined leftward and downward on the outer surface of the left outer wall 161. The waterproof wall 27 is formed of the lower outer wall 16l.
The left end of d is formed integrally with the lower outer peripheral wall 16d by extending leftward. The waterproof walls 26 and 27
When the amount of protrusion of the waterproof wall 27 to the left is compared, the amount of protrusion of the waterproof wall 27 to the left is equal to or slightly smaller than that of the waterproof wall 26.

The waterproof wall 26 has a function of guarding water or the like flying from above or from the side from entering the second space 24b through the notch 17 of the outer peripheral wall 16, and the waterproof wall 27 from below. And has a role of guarding the splash water or the like from entering the second space 24b through the notch 17 of the outer peripheral wall 16.

Thus, in the second embodiment,
When the lid 19 is closed, the filter 25 becomes the first space 24a.
Of these, it is fitted into the portion except for the passage 15p (see FIGS. 14 and 15), so that it is possible to prevent dust and dirt from entering the lamp chamber 5 with the flow of air. Then, as shown in FIG. 15, when the filter 25 is located in the first space 24a, the filter 25 is partially compressed between the cylindrical portion 13 and the lid portion 19 of the communication hole 12. As the density of the filter holes gradually increases from the passage 15p to the communication hole 12, dust and the like adhere to the entire filter in a well-balanced manner, thereby improving the dustproof effect. That is, for the purpose of dust prevention only, the filter 25 is achieved simply by arranging it in the first space 24a.
The reason why the filter 25 is attached to the concave portion 21 of the filter 9 is as follows.
This is because, in addition to preventing falling off, the density distribution of the filter pores is assured to be a predetermined distribution.

FIGS. 16 and 17 show a third embodiment of the vehicular lamp according to the present invention, which is different from the first embodiment only in the shape of the outer peripheral wall and the impermeable wall in the ventilation portion. Therefore, only the ventilation part 11B is shown.

15U and 15D are impermeable walls. One of the impermeable walls 15U extends rightward from a position slightly above the lower end of the left eaves wall 141 and ends before the right eaves wall 14r. . The impermeable wall 15D extends leftward from the lower end of the right eave wall 14r and ends short of the lower end of the left eave wall 14l. A passage 15p is formed between the impermeable walls 15U and 15D.

Reference numerals 28 and 29 denote waterproof walls formed integrally with the outer peripheral wall 16.

The waterproof wall 28 is inclined downward to the left on the outer surface of the left outer wall 161 and is formed integrally with the left outer wall 161. The waterproof wall 29 is formed by forming the left end of the lower outer wall 16d at the left end. By extending downward and to the left, it is formed integrally with the lower outer peripheral wall 16d. The waterproof walls 28 and 29
When the amount of protrusion of the waterproof wall 29 to the left is compared, the amount of protrusion of the waterproof wall 29 to the left is equal to or slightly smaller than that of the waterproof wall 28.

The waterproof wall 28 has a function of guarding water or the like flying from above or from the side from entering the second space 24b through the notch 17 of the outer peripheral wall 16. Has a role of guarding splashing water or the like from below from entering into the second space 24b through the notch 17 of the outer peripheral wall 16.

[0059]

As is apparent from the above description, according to the first aspect of the present invention, since the lid is formed integrally with the second peripheral wall, another member such as a waterproof pipe can be formed. This is unnecessary, and the cost can be reduced. In addition, a first space formed between the lamp body, the first peripheral wall, and the lid, and a second space formed between the lamp body, the first and second peripheral walls, and the lid. By forming the air passage having a double structure consisting of: a high sealing property is not required between the lid and the peripheral wall, and the first space and the second space are not required.
By arranging the first passage connecting the second space and the opening of the second passage connecting the second space and the outside so as not to face each other, water from the outside passes through the second space. Thus, it is possible to prevent the intrusion into the first space, that is, the lamp room.

According to the second aspect of the present invention, the inner surface of the lid is brought into contact with the protruding end of the first peripheral wall so that the inner surface of the lid is formed between the lamp body, the lid and the first peripheral wall. A space between the lamp body, the lid, the first peripheral wall, and the second peripheral wall by contacting the side edge of the lid with the inner surface of the second peripheral wall. The second space is formed, and the direction in which the lid abuts on the first peripheral wall is different from the direction in which the lid abuts on the second peripheral wall. And the second peripheral wall portion can be brought into contact with each other in a sufficiently close contact state.

According to the third aspect of the present invention, the first
And the second peripheral wall portion is provided on the rear wall of the lamp body, and the opening of the second passage is directed toward the center of the lamp, so that water coming from the side of the lamp due to splashing or the like is formed in the second passage. The effect that it is difficult to enter the opening can be obtained.

According to the fourth aspect of the present invention, by disposing a dustproof filter member in the first space,
It is possible to prevent dust and the like from entering the lighting room.

It should be noted that the specific shapes and structures shown in the above embodiments are only a few examples for embodying the present invention, and these limit the technical scope of the present invention. Not to be interpreted.
