Description

[Detailed Description of the Invention] The present invention relates to a lever box for an automobile.

Nowadays, the handbrake lever installed between the driver's seat and the passenger's seat is usually equipped with a D-box made of resin that covers the lever.

An opening is formed in this box over the range of rotation of the lever, and a cover is attached to the opening so that the gears, wires, etc. inside are not visible from the outside through this opening.

1 and 2 show a conventional cover mounting structure.

In the figure, 1 is a resin box, 2 is an opening provided over the 0-rotation range of the handbrake lever (not shown) of box 1, and 3 is a protrusion molded at a circumferential position on the back side of opening 2. 4 is a cover for the opening 2 having an insertion hole 5 corresponding to the pin 3 and an opening 6 for operating the lever; 7 is a frame-shaped rigid body having an insertion hole 8 corresponding to the pin 3. It is a molded frame.

The cover 4 is made of resin molded into a flat plate shape and has flexibility.

To attach the cover 4, first fit the pin 3 into the insertion hole 5 of the cover 4, fit the hard molded frame 7 onto the pin 3 in the same way, overlap the cover 4, and then insert the tip of the pin 3. Heat and swage (see Figure 2).

However, in such a cover 40 mounting structure, the curved shape of the box 1 is firmly attached only to the part caulked by the pin 3, and the box 1 may be affected by heat such as solar heat. When it gets hot, the cover 4 between the pins 3 sometimes bends.

Furthermore, since a heating crimping process is provided, the equipment required for this process increases, and furthermore, the increased number of processes leads to a decrease in work efficiency.

In view of the above-mentioned drawbacks of the conventional lever box for automobiles, the present invention has been developed to improve and eliminate these drawbacks.

The configuration of the present invention will be explained below according to the embodiments shown in the drawings.

Note that parts with the same symbols as those in the conventional version are the same members.

In the present invention, as shown in FIGS. 3 and 4, a support piece 9 is integrated on the longitudinal back side of the lever operation opening 2 of the box 1, and a locking claw 10 is integrated on the other side. Extrusion molding,
Further, a pin 11 for positioning the cover 4 in the vehicle width direction is integrally formed to protrude from the side edge of the back side of the opening 2.

An insertion hole 12 is provided at a location corresponding to the support piece 9 of the cover 4, the locking pawl 10, and the vehicle width direction positioning pin 11.

Reference numeral 13 denotes a highly rigid frame made of steel wire or resin.

The grooves 14 and 15 of the support piece 9 and the locking claw 10 are set to dimensions such that a pressing force is applied to the cover by the rigid frame 13.

In addition, the dimensions of both ends 13a and 13b of the rigid frame 13 corresponding to the support piece 9 and the locking claw 10 are
It is preferable that the dimensions of the grooves 14 and 15 of 0 are approximately the same or slightly larger.

To attach the cover 4 to the box 1, first, the support piece 9, the locking claw 10, and the pin 11 are fitted into the insertion hole 12 of the cover 4, and the cover 4 is held by the support piece 9 and the locking claw 10.

Then, one side of the steel wire frame 13 is supported by the support piece 13 (the state indicated by the chain line in FIG. 4), and the steel wire frame 13 is rotated about this support point as the rotation center, and the other side is supported by the locking claw 10.
Fit into.

In this case, the support piece 9 and the locking pawl 10 are resin molded parts that are integrally molded with the box 1 and have elasticity, so that they constantly apply an upward force to the cover 4 via the steel wire frame 13. Press it against box 1.

Also, both ends 13a of the tonality frame. When the dimensions of the grooves 13b are made slightly larger than the dimensions of the grooves 14 and 15 of the support piece 9 and the locking pawl 10, elasticity is imparted to the rigid frame 13, and a stronger upward force is applied to the cover 4.

Therefore, with this mounting structure, the steel wire frame 13 can press the cover 4 to the box 1 around almost the entire circumference of the box opening 2, and can prevent the intermediate portion from being bent.

Also, the installation work is extremely simple.

Note that the cover 4 is regulated in the vehicle width direction by positioning pins 11, so that it will not shift due to vibrations of the vehicle body or the like.

In this way, in the present invention, a support piece is integrally formed to protrude from the back side of the lever operation opening of the box on the negative side in the longitudinal direction, and a locking claw is integrally formed on the other side, and the flat cover of the opening is formed to support this support piece. One side of the frame-shaped rigid frame is supported by the support piece, and the other side of the rigid frame is fitted into the locking pawl with this support part as the center of rotation. Since the cover is supported in pressure contact with the back surface of the box by the elasticity of the locking claws or the elasticity of the rigid frame, it is possible to prevent the intermediate portion of the cover from bending, and to significantly simplify the installation work.

Therefore, it is possible to improve work efficiency and reduce costs.
