Description

[Detailed explanation of the idea] The present invention relates to a pedal arm mounting structure for a pedal device.

In conventional pedal devices, from the viewpoint of waterproofing and appearance,
Some models have a bracket covering the area around the pedal arm attachment point.

By the way, in such conventional devices, the pedal arm is attached by rotatably supporting the pedal arm on a bracket using a pin, and then attaching the bracket to the body. Since the arm is indirectly supported by the body via the bracket, if the bracket is deformed due to manufacturing or installation errors in the bracket mounting surface of the bracket arm and the body, the pedal mechanism will tilt and play will occur. This not only hinders smooth operation, but also causes the pedal force to be applied directly to the bracket, which can cause the tilt and backlash, especially if the bracket is made of a weak material such as synthetic resin. When used for a long period of time, deformation increases and cracks occur mainly at the attachment part of the pedal arm.

However, the present invention is intended to solve the above-mentioned conventional problems, and involves inserting a shaft body such as a bolt into the bracket at the position of the rotation axis of the pedal arm, and fixing the shaft end of the shaft body to the body. The present invention is characterized in that the various problems mentioned above are solved by fixing a bracket on the shaft body and rotatably supporting the pedal arm on the mouth of the shaft body.

Next, an embodiment in which the present invention is applied to an accelerator pedal device will be described.

As shown in FIGS. 1 to 3, an open part 2a is formed at the upper part of the rear surface in the front-rear direction of the vehicle in a hollow frame 1 having a sidewall shape and having a required width and opening at the bottom. As shown in FIG. 3, a pair of opposing holes 3 and 4 are bored on both sides of the bracket 1.

On the other hand, the pedal arm 7 consists of a rod-shaped arm piece 8 and a mounting piece 9. As shown in FIG. As shown in FIG. 1, the rear end of the base portion 8a is bent and extended laterally at a substantially right angle, and the intermediate portion 8c and the tip of the intermediate portion 8c are bent rearward in the longitudinal direction of the vehicle to integrate the pedal attachment portion 8d. The mounting piece 9 is formed by molding a metal plate into a rail shape with a U-shaped cross section, as shown in FIGS. A pair of holes 9 facing each other on both sides near one end are welded to the joint end 8b of 8.
It is formed by drilling holes a and 9b.

The pedal arm 1 is inserted into the bracket +-i from the mounting piece 9 side through the opening 2a of the bracket 1, and the pair of holes 9a and 9b of the mounting piece 9 are coaxial with the pair of holes 3 and 4 of the bracket 1. The sleeves 5 and 6 are driven into the pair of holes 3 and 4 of the bracket 1 from the outside of the bracket 1, and the sleeves 5 and 6 are fixed to the bracket 1, and a pedal arm γ is attached to the tips of the sleeves 5 and 6. Small diameter portions 5a, 6a with outer diameters that approximately match the diameters of the pair of holes 9a, 9b of the piece 9
The small diameter portions 5a, 6a are fitted into the pair of holes 9a, 9b of the mounting piece 9 of the pedal arm 7 to rotatably support the pedal arm 7 on the sleeves 5, 6. As shown in detail in FIG. 3, a bolt 10 is inserted into the through holes 5b, 6b of the sleeves 5, 60, and the bolt 10 approximately matches the diameter of the through holes 5b, 6b of the sleeves 5, 60 toward the shaft end. The bolt 1
0 to one side of the bracket 1, pass the large diameter portion 10a between the sleeves 5.6, and then attach the bracket 1.
The small diameter portion 10b is inserted with the small diameter portion 10b protruding from the other side.

The small diameter portion 10b of the bolt 10 protruding from the other side of the bracket 1 is inserted into the hole 11 formed in the inner plate A of the body as shown in FIG. The bolt 10 is fixed to the inner plate A by screwing together.

The button 13°14.15 in FIG. 1 is a washer that can be inserted between the bracket 1 and the inner plate A.

Thus, the bracket 1 connects one point to the inner plate A with the bolt 10.
By tightening the bracket 1 to the inner plate A with the bolt 16, the bracket 1 is attached to the body with the intention of simply restricting the rotation of the bracket 1 around the bolt 10 at another appropriate point. It is fixed to the inner plate A.

A pedal piece 17 is attached to the pedal attachment part 8d of the rod-shaped frame piece 8 on the pedal arm 7, and a tip of a wire 18 is inserted into the lower end of the attachment piece 9 through an opening 2b provided at the lower end of the back surface of the bracket 1. and wrapping the coil spring 19 around the bolt 10,
One end of the spring 19 is locked into a hole 9d formed in the mounting piece 9 of the pedal arm 7, and the other end is brought into contact with the inner surface of the bracket 1, so that the repulsive force of the spring 190 causes the pedal arm 7 to move as shown in FIG. The bracket 1 is always biased to rotate counterclockwise, and a stopper 20 is provided on the inner surface of the bracket 1 to restrict the counterclockwise rotation position.
It is forced to protrude.

In the present fl device having the above configuration, as described above, the bolt 10 fixed to the inner plate A is inserted into the rotation axis position of the pedal arm 7 of the bracket 1, and the bracket 1 is stopped by the bolt 10. Therefore, even if a load due to pedal depression force applied when operating the pedal arm 1 is applied to the sleeve 5°6 of the bracket 1 that supports the pedal arm 7, the load is transferred to the bolt 10 via the sleeves 5 and 6. Since the receiver is stopped, deformation of the bracket 1 due to the load being applied to the entire bracket 1 can be prevented.

In addition, since the bracket 1 is attached to the bolt 10 fixed to the mounting part of the bracket 1 and the pedal arm 7, and to the inner plate A, any deformation during manufacture or installation of the bracket 1 can be done using the bolt 10 fixed to the inner plate A as the pivot point. Since the pedal arm γ is regulated by this, the tilting or wobbling of the pedal arm γ rotatably supported on the sleeves 5 and 6 is naturally small.

By the way, in the above embodiment, the pedal arm 7 is rotatably supported on the sleeves 5 and 6 of the bracket 1 supported by the bolt 10, but it is also possible to directly support the pedal arm 7 rotatably on the bolt 10. In this case, the bolt 10 completely supports both the bracket 1 and the pedal arm T, and the deformation of the bracket 1 has no effect on the attachment of the pedal arm 7.

As explained above, in the present invention, in a pedal device, a suitable shaft body such as a bolt is inserted into the bracket at the rotation axis position of the pedal arm, and the shaft end of the core shaft body is fixed to the body, and the bracket is fixed to the shaft body. At the same time, by attaching the pedal arm rotatably around the shaft body, displacement of the pedal arm due to deformation of the bracket is restricted, or the pedal arm is attached regardless of the deformation of the bracket to ensure operability of the pedal arm. This structure reduces or prevents the deformation of the bracket due to loads such as part of the pedal depression force, and prevents the bracket from breaking.The structure also supports the bracket to the body using bolts as described above. This method is highly effective for resin brackets.
