Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ventilator grill assembly structure for a vehicle instrument panel.

[Prior art] The conventional ventilator grill assembly structure is as follows:
For example, there are those shown in FIGS. 1 to 4 (see Japanese Utility Model Application No. 57-97712). In the figure, reference numeral 1 denotes a ventilator grille, which is communicated with a duct 13 protruding from a cooling/heating device 12, and the wind passing through the duct 13 is sent into the vehicle interior through an air outlet 1a. The ventilator grill 1 has horizontal louvers 2, vertical louvers 3, etc. built-in so that the wind direction can be adjusted. Reference numeral 4 denotes a shut valve, and the air volume can be adjusted by opening and closing the shut valve 4.

Such a ventilator grill 1 is inserted from the front of the instrument panel 5 into an opening 5a formed in the front of the instrument panel 5,
The ventilator 1 is attached with one touch by engaging the claw 6 formed on the ventilator 1 with the rear edge 5b of the opening of the instrument panel 5 (FIGS. 2 and 3). The surface of the instrument panel 5 is covered with an elastic pad 7, and a cluster 8 covers the parts where units such as a heater controller 9 and a radio 10 are mounted. For example, the cluster 8 is mounted with screws 11 facing upward in a recess in which the heater controller 9 is attached, and is mounted so that the screws 11 are not visible from the viewpoint of appearance.

On the other hand, FIG. 4 shows the instrument panel 5.
An example of a ventilator grille 15 is shown that is inserted into the opening 5a and attached to the instrument panel 5 with screws 11 from the inside.

However, the claw 6 shown in FIGS.
In the one-touch ventilator grille assembly structure according to the present invention, if there is a dimensional variation in the ventilator grille 1 with respect to the opening 5a of the instrument panel 5, the ventilator grille 1 will play or become impossible to assemble. Additionally, once assembled, it is difficult to remove the ventilator grille 1 from the front when removing something that was accidentally put into the ventilator grille 1 during use, or when the louvers 2, 3 or the shut valve 4 break down. It was becoming a costly repair. In addition, since there is a resilient claw 6 on the outside of the ventilator grille 1, the dimension a shown in FIG. It was getting bigger than it needed to be. Air outlet 1
Narrowing the diameter of a will impair the function of the ventilator grille 1.

In addition, the instrument panel 5 shown in FIG.
In the case of a ventilator grille assembly structure in which the instrument assembly is inserted from inside and attached from the same direction with screws 11, once the instrument assembly is assembled to the vehicle body, it cannot be removed from the front of the instrument panel 5. In the case of the above-mentioned repair, the instrument assembly must be removed from the vehicle body and the repair must be carried out from inside the instrument panel 5. Furthermore, since the ventilator grille is assembled from the rear, processing of the surface end (parting) 14 is restricted and a gap is created, or the front edge 5c of the opening of the instrument panel 5 is
was exposed, causing problems with appearance.

[Object of the Invention] An object of the invention is to facilitate the assembly and repair work of a ventilator grill.

Another purpose is to absorb product variations in the ventilator grille and to allow the ventilator grille to be securely fixed without rattling.

Still another purpose is to ensure the discharge capacity of the ventilator and to increase the degree of freedom in designing the arrangement of equipment on the instrument panel.

Still another object is to improve the appearance of the joints of parts and cover the screwed parts with clusters.

[Structure of the Invention] Therefore, the present invention involves inserting the ventilator grille into the opening of the instrument panel from the front, and engaging the instrument panel at the upper part of the ventilator grille while restricting movement in the upward and longitudinal directions. Attach the mounting section at the bottom of the grill to the instrument panel from the front and secure it with screws, and fit the tip of the cluster into the groove provided between the mounting section and the vent of the ventilator grill. The ventilator grille is attached by covering the parts and screws with the cluster, and pressing the ventilator grille upward and backward.

[Example] The present invention will be explained below based on the drawings.

FIGS. 5 to 7 are diagrams showing an embodiment of the present invention. In the drawings, parts or members that are the same or equivalent to those of the conventional example are given the same reference numerals, and redundant explanations will be omitted.

First, to explain the configuration, ventilator grill 3
0 is provided with a horizontal louver 2, a vertical louver 3, and a shut valve 4 inside.

The upper part of the ventilator grille 30 is formed with a protrusion 30a that engages with the rear edge 5b of the opening 5a of the instrument panel 5, and a front edge 30b that engages with the front edge 5c of the opening.
and the ventilator grille 3 by the leading edge 30b.
An engaging portion 31 is formed that restricts movement of 0 in the front-rear direction and upward. Further, a mounting portion 33 is suspended from a lower portion of the ventilator grille 30 via a groove portion 32. The groove portion 32 is provided on the front side of the ventilator grille 30 outside the air outlet 1a and reaching the attachment portion 33. This mounting part 33
is in contact with the front side of the instrument panel 5 and is fixed with screws 11.

The cluster 35 covers units such as the heat controller 9 and the radio 10 from the front so that they can be operated, and further covers the mounting portion 33 and screws 11 of the ventilator grille 30, and the upper end portion 34 is fitted into the groove portion 32 to attach the instrument panel. It is attached to 5. In this embodiment, the cluster 35 is attached to the instrument panel 5 with screws 11 from below in a recess that covers the heater controller 9 of the cluster 35. This cluster 3
5 is attached so that the upper end portion 34 is fitted into the groove portion 32 to press and urge the ventilator grille 30 upward and rearward (instrument panel 5).

Next, the installation and removal of the ventilator will be explained.

Insert the ventilator grille 30 from the front into the opening 5a of the instrument panel 5 covered with the pad 7, with the tip slightly downward, so that the engaging part 31 is in a position corresponding to the periphery of the opening 5a, and then the rear edge 5b of the opening is connected to the opening 5a. The projection 30a and the front edge 5c of the opening are engaged with the front edge 30b to restrict movement of the ventilator grille 30 in the front-rear direction and upward. Then, the lower mounting portion 33 of the ventilator grille 30 is brought into contact with the instrument panel 5 and fixed with the screws 11 to attach the ventilator grille 30 to the instrument panel 5. In addition, although the installation state is omitted in the figure, the screw 11 that covers all but the operation parts of the unit installed on the instrument panel 5, such as the heater controller 9 and the radio 10, and that the above-mentioned ventilator grille 30 is installed.
Cover the cluster 35 from the front and tighten the screw 1.
Attach it to the instrument panel 5 in step 1. At this time, the upper end portion 34 of the cluster 35 is fitted into the groove portion 32 of the ventilator grille 30, and presses and urges the ventilator grille 30 upward and backward (into the instrument panel 5) to prevent the ventilator grille 30 from wobbling. .

The instrument panel assembly assembled in this way is put into the production line, and the cooling and heating equipment 12 and duct 13 attached to the vehicle body are assembled.
The assembly to the vehicle is completed by connecting the ventilator grille 30 to the ventilator grille 30, etc.

Next, a case will be described in which the ventilator grill 30 is removed during use or for reasons such as repair.

First, screw 11 in front of heater controller 9
Cluster 35 is removed by removing . Then, by removing the exposed screws 11 from the front, the mounting portion 33 is pulled out forward, the upper engagement is released, and the ventilator grille 30 is pulled out from the duct 13 and removed from the opening 5a of the instrument panel 5.

After the necessary repairs are completed, assembly can be performed in the reverse order.

[Effect of the invention] As explained above, according to this invention,
A ventilator grill with an air outlet has an engaging part at the top and a mounting part at the bottom so that the ventilator grill can be attached from the front of the instrument panel, and a groove between the outside of the air outlet and the mounting part. , attach such a ventilator grille to the instrument panel with screws, cover the screws and the mounting part with a cluster, and insert the tip of the cluster into the groove to press the ventilator grille upward and backward to install the instrument panel. The ventilator grill assembly structure is attached to the panel, resulting in the following effects.

Assembling the ventilator grill becomes easier.
This is particularly effective when it comes to repairs. The fixation of the ventilator grille to the instrument panel is reliable, there is no rattling compared to the conventional engagement using claws, and even if there is a variation in product dimensions, this is absorbed to a greater extent than before. In addition, because of the claws provided on the outside of the ventilator grille, it is possible to either reduce the area of the ventilator grille outlet to reduce performance, or increase the opening for attaching the ventilator grille without changing the area and install other items on the instrument panel. However, it is no longer necessary to take these into consideration, and flexibility in the performance of the ventilator grill and equipment arrangement design can be secured. Furthermore, since the ventilator is inserted from the front, the parting for fitting the parts is neat, and the screw-fastening parts are covered with clusters, which improves the appearance.
