[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a temporary holding part for temporarily holding a door mirror base assembly to which a door mirror is attached, when the door mirror base assembly is assembled to the vehicle body.

[0002]

2. Description of the Related Art When a door mirror is attached to a door of a vehicle body, it is attached via a door mirror base assembly (hereinafter, appropriately abbreviated as a base assembly).

In this base assembly, a door mirror body is attached to the front surface of a door mirror base, and a gasket is provided on the back surface. The gasket is a vehicle body panel such as a door outer panel or a gusset provided between the door sash and the door panel. It is attached to these body panels so as to be in close contact with.

The door mirror body may be attached after the base assembly is assembled to the vehicle body or may be previously attached before the base assembly is assembled to the vehicle body.

As a door mirror assembly in which the door mirror body is assembled in advance to the base assembly, there is known one disclosed in Japanese Utility Model Publication No. 7-19905.

By the way, when the base assembly is attached to the vehicle outer panel such as the door outer panel or the gusset described above, the base assembly is arranged at a predetermined position of the vehicle body panel from the outside of the vehicle compartment and temporarily held, and then this temporary assembly is used. The held base assembly is attached to the vehicle body panel from the vehicle interior side with bolts, screws, etc., and is fully mounted.

Therefore, a temporary holding portion for temporarily holding the base assembly on the vehicle body panel is provided in the base assembly.

For example, in the above-mentioned Japanese Utility Model Publication No. 7-19905, the lower side of the door mirror harness passage hole is extended substantially horizontally from the base assembly and penetrates through the door mirror harness passage hole opened in the vehicle body panel. It has a locking claw that is locked to the peripheral edge.

Then, with the base assembly in close contact with the vehicle body panel via the gasket, the locking claws of the base assembly are hooked on the door mirror harness passage holes of the vehicle body panel to temporarily hold the base assembly on the vehicle body panel. ing.

[0010]

However, since the locking claws are hooked on the lower peripheral edge of the door mirror harness passage hole only by frictional force, a slight impact is applied to the base assembly. However, the locking claw may easily come off from the lower peripheral edge.

Further, when the leg portion extending substantially horizontally from the base assembly is largely bent, it may fall off.

The present invention has been made in view of the above circumstances, and provides a structure of a temporary holding portion of a door mirror base assembly in which the door mirror base assembly does not easily drop from a temporary holding state on a vehicle body panel. To aim.

[0013]

In order to solve the above problems, the structure of the temporary holding portion of the door mirror base assembly according to claim 1 of the present invention comprises a gasket on one surface side of the door mirror base, and Prior to the main mounting of the door mirror base assembly, in which the door mirror body is arranged on the other surface side of the door mirror base, to the vehicle body panel provided on the door of the vehicle body and extending in a substantially vertical direction via the gasket. , In a state where the door mirror base assembly is in close contact with the vehicle body panel via the gasket, extends substantially horizontally from the door mirror base assembly, and penetrates a locking hole opened in the vehicle body panel to be locked to the vehicle body panel. Door mirror base assembly for temporarily holding the door mirror base assembly on the vehicle body panel. A structure of a temporary holding portion of an assembly, wherein the temporary holding portion is a leg portion that extends horizontally from the door mirror base assembly toward the vehicle body panel, and is folded back upward from a tip of the leg portion. It is characterized in that the hook portion is engaged with the vehicle body panel, and the hook portion is formed such that an end surface that abuts on the vehicle body panel is convex upward.

Here, the vehicle body panel may be a door outer panel, or a gusset or the like additionally provided between the door panel and the door sash for attaching a door mirror.

Further, the upward convex means that the shape of the hook portion projected on the vehicle body panel is substantially fan-shaped, and the upper edge is formed in a convex curved line.

According to the structure of the temporary holding portion of the door mirror base assembly (hereinafter, abbreviated as a base assembly as appropriate) according to claim 1 of the present invention thus constructed, the temporary holding portion penetrating the vehicle body panel is provided. The end surface of the hook portion is abutted and locked to the inner side surface of the vehicle body panel in the passenger compartment, but since the end surface of this hook portion is formed to be convex upward, the end surface in contact with the vehicle body panel is wide. Formed,
Since the area of this end face, that is, the locked area is large, the locking with the vehicle body panel is not easily released.

Further, since the hook portion is folded back upward with respect to the leg portion of the temporary holding portion, the hook portion is hooked on the peripheral edge above the engaging hole of the vehicle body panel, but is arranged outside the vehicle compartment of the vehicle body panel. Due to the self-weight of the installed base assembly, the base assembly descends downward on the outside of the vehicle body panel compartment, and the leg and hook parts rise upward on the inside of the vehicle body panel compartment. .

Here, the acting rotational moment is
Since the moment is in the direction opposite to the direction in which the hook is unlocked, that is, in the direction in which the lock becomes firm, the hook does not easily come out of the temporary holding state, and the base assembly is impacted or temporarily held. It is possible to prevent the base assembly from easily falling off from the vehicle body panel even if the legs of the section are largely bent.

Further, in the state where the leg portion of the temporary holding portion and the hook portion folded back from the leg portion are being inserted into the locking hole of the vehicle body panel, in the direction in which the hook portion approaches the leg portion,
Since the connection between the hook and leg is elastically deformed,
Once the hook portion is locked to the vehicle body panel, the locking is not released unless a load is artificially applied to bring the hook portion close to the leg portion or the temporary holding portion is deformed.

Therefore, also from this point, it is possible to prevent the base assembly from easily falling off from the vehicle body panel.

When it is desired to remove the temporarily held base assembly from the vehicle body panel, the hook portion and the leg portion should be sandwiched by fingers, and a load should be applied so that the hook portion and the leg portion come close to each other to elastically deform the temporary holding portion. Thus, the temporary holding portion can be passed through the locking hole of the vehicle body panel, and can be easily removed from the vehicle body panel when desired.

The structure of the temporary holding portion of the door mirror base assembly according to claim 2 of the present invention is the structure of the temporary holding portion of the door mirror base assembly according to claim 1, wherein the temporary holding portion is the gasket. Is formed by erecting a part of it on the vehicle body panel side.

According to the structure of the temporary holding portion of the door mirror base assembly according to claim 2 of the present invention thus constructed, in addition to the operation and effect of claim 1, a part of the existing gasket is used. By forming the temporary holding portion by using it, there is an effect that it is not necessary to use a separate member and an increase in manufacturing cost can be suppressed.

Further, the structure of the temporary holding portion of the door mirror base assembly according to claim 3 of the present invention is the structure of the temporary holding portion of the door mirror base assembly according to claim 2, wherein the leg portion of the gasket is A rib that abuts from the side of the door mirror base near the rising edge,
It is characterized in that it is formed on the door mirror base.

According to the structure of the temporary holding portion of the door mirror base assembly according to the third aspect of the present invention thus constructed, in addition to the function and effect of the second aspect, the hook portion serves as the locking hole. In the locked state, that is, when the base assembly is temporarily held by the vehicle body panel,
When a load is applied so that the base assembly is not held by the vehicle body panel, the load is applied in the direction in which the entire temporary holding portion is pulled out from the locking hole while the end surface of the hook portion remains hooked on the upper peripheral edge of the locking hole. To work.

As a result, the gasket in the vicinity of the leg rising portion is dented and deformed toward the outside of the passenger compartment. When such deformation occurs, it cannot be reused as a base assembly without replacing the gasket.

However, by bringing a rib formed on the door mirror base into contact with the deformed gasket portion, that is, a portion near the rising edge of the leg portion, the deformed portion is prevented from being deformed by the abutted rib. It

Therefore, even if an unreasonable load acts on the base assembly in the temporarily held state, it can be reused as it is without replacing the gasket, and from this point as well, an increase in manufacturing cost can be suppressed. .

When the vehicle body panel and the gasket are separated from each other, wind, rainwater, or the like enters between the vehicle body panel and the gasket. Then, in the structure of the temporary holding portion of the base assembly according to claim 2, the infiltrating rainwater and the like descends inside the base assembly through the opening of the gasket cut out from the temporary holding portion, and the base assembly and the vehicle body. The structure of the temporary holding portion of the base assembly according to claim 3 penetrates into the vehicle interior through a fastening hole formed in the panel for fastening them, but in the structure of the temporary holding portion of the base assembly, the rib supporting the rising portion of the leg portion of the gasket is the base portion. Since the inner space of the assembly is divided into upper and lower parts, rainwater and the like that have entered the interior of the base assembly are prevented from falling by the ribs and do not enter the lower inner space that communicates with the vehicle interior.

Further, the structure of the temporary holding portion of the door mirror base assembly according to claim 4 of the present invention is the same as the structure of the temporary holding portion of the door mirror base assembly according to claim 2 or 3, It is characterized in that a tilt-preventing rib for preventing the leg portion from falling down is formed by connecting with a portion near a rising portion of the portion.

In the temporary holding state, the hook portion is hooked on the upper edge of the locking hole of the vehicle body panel, but here, the base assembly is pulled toward the outside of the vehicle compartment, and the leg portion is attached to the leg portion. When a load is pulled back to the outside of the vehicle, the hooks and legs tilt downwards,
The end surface of the hook may slide upward along the vehicle body panel and separate from the vehicle body panel, and the temporary holding state of the base assembly may be released.

However, according to the structure of the temporary holding portion of the door mirror base assembly according to claim 4 of the present invention, in addition to the actions and effects described in the corresponding claims of claims 2 and 3, the leg portion is provided. The load that acts to incline the
It is transmitted to the tilt prevention ribs connected to the legs.Since the tilt prevention ribs are connected to the rising portions of the legs, the legs cannot be deformed in the range where the rising portions of the legs are not deformed. Does not tilt downward, and therefore, the engagement between the hook portion and the vehicle body panel is prevented from being released, so that the temporary holding state of the base assembly can be made stable.

The structure of the temporary holding portion of the door mirror base assembly according to claim 5 of the present invention is the structure of the temporary holding portion of the door mirror base assembly according to any one of claims 2 to 4. The door mirror base is formed with a tilting prevention portion that extends from the door mirror base to a lower side of the leg portion and prevents the leg portion from falling down.

In the temporary holding state, the hook portion is hooked on the upper edge of the locking hole of the vehicle body panel, but here, the base assembly is pulled toward the outside of the vehicle compartment, and thus the leg portion is attached to the leg portion. When a load is pulled back to the outside of the vehicle, the hooks and legs tilt downwards,
The end surface of the hook may slide upward along the vehicle body panel and separate from the vehicle body panel, and the temporary holding state of the base assembly may be released.

However, according to the structure of the temporary holding portion of the door mirror base assembly according to the fifth aspect of the present invention, in addition to the actions and effects described in the corresponding claims among the second to fourth aspects, the door mirror base can be provided. Since the formed tilting prevention portion prevents the leg portion from falling down, the leg portion does not tilt downward, and therefore, the engagement between the hook portion and the vehicle body panel is prevented from being released, Therefore, the temporary holding state of the base assembly can be made stable.

Then, a tilt preventing rib is formed which connects the leg portion and a portion in the vicinity of the rising of the leg portion.
If a load exceeding the load that does not deform the part near the rising edge of the leg acts and the part near the rising part of the leg is deformed and the tilting prevention rib cannot prevent tilting of the temporary holding part, this tilting prevention This is particularly effective because the part can prevent the temporary holding part from tilting.

When the tilt of the leg portion 14a becomes excessively large, the leg portion 14a is broken and the temporary holding portion 1
The function of 4 is impaired, and the temporary holding state is inadvertently released.

When the function of the temporary holding portion 14 is impaired, the temporary holding portion 14 must be replaced together with the gasket 12.

However, according to the structure of the temporary holding portion 14 of the door mirror base assembly 10 of the third embodiment, the leg portion 1
As shown in FIG. 8, the load acting to incline 4a downward is transmitted from the leg portion 14a to the continuous inclination preventing rib 14d. The inclination preventing rib 14d has an end face of the leg portion 14a of the gasket 12. Since it is in contact with the rising vicinity portion, the leg portion 14a does not tilt downward under a load in a range where the rising vicinity portion is not deformed.

Therefore, in addition to the same operation and effect as in the second embodiment, the engagement between the hook portion 14b and the gusset 33 is firmly prevented from being released, so that the temporary holding state of the base assembly 10 is further stabilized. It can be (Fourth Embodiment) FIG. 10 is a sectional view corresponding to FIG. 4, showing a structure of a temporary holding portion of a door mirror base assembly according to a fourth embodiment of the present invention.
