Description

  The present invention relates to a mounting dimension adjusting member.

  As a conventional technique, there is known an attachment dimension adjusting member capable of attaching and removing a bearing portion of a brake lamp switch to and from an adjuster without consideration more than necessary (for example, Patent Document 1).

The mounting dimension adjusting member of Patent Document 1 includes a brake lamp switch and an adjuster, and a thread is partially provided on the outer wall of the bearing portion of the brake lamp switch, and a thread is partially provided on the inner wall of the adjuster. The brake lamp switch bearing is inserted into the adjuster and rotated in the opposite direction at the desired position, and the brake lamp switch thread and the adjuster thread are provided at the thread end of the adjuster. By screwing together to the position of the stopper, the bearing portion of the brake lamp switch can be positioned and fixed to the adjuster. Further, by providing the stopper, a fixing nut is not required for positioning and fixing, and at the same time, the mounting time can be shortened. In addition, because the thread end of the brake lamp switch and the thread end of the adjuster, which is the rotation stopper, are formed in a direction that bites into each other, the stopper strength during rotation increases and the adjuster is deformed by excessive tightening. Since there is no risk of damage, it is not necessary to consider more than necessary for installation and removal.

Below, the attachment dimension adjustment procedure of the attachment dimension adjustment member in the 1st Embodiment of this invention is demonstrated, referring each figure.

  When the driver of the vehicle 1 steps on the pedal pad 21, the brake pedal 20 rotates and pressure is applied to the hydraulic cylinder 24. The hydraulic cylinder 24 transmits the applied pressure to the hydraulic brake 10b. Simultaneously with the transmission of pressure, the counter magnet 26D moves following the rotation of the brake pedal 20, and the ECU 100 receives the output voltage of the brake lamp switch 26 based on the distance between the counter magnet 26D and the brake lamp switch 26. The received output voltage is compared with the threshold value of the storage unit 101, and the lighting control of the brake lamp 10a is performed based on the determination result. The mounting dimension adjusting member 2 adjusts the distance x1 at the initial position between the counter magnet 26D and the brake lamp switch 26.

  First, from the state shown in FIG. 5B, the adjuster piece 27F and the adjuster piece 28F are integrated into an adjuster 26F, and the adjuster 26F is attached to the attachment hole 220a of the attachment portion 22a. Next, the bearing portion 26E is inserted into the adjuster 26F. After inserting the adjuster 26F to a desired position, the bearing portion 26E is rotated clockwise with respect to the adjuster 26F, so that the stopper groove 261E and the stopper 260F are fitted to fix the bearing portion 26E and the adjuster 26F. Thus, the state shown in FIG.

  The adjustment of the initial position x1 of the bearing portion 26E is performed according to the following procedure. First, the initial position of the brake pedal 20 indicated by the solid line in FIG. Next, when the brake pedal 20 is in the initial position, the bearing portion 26E is inserted into the adjuster 26F, and is inserted to a position where the tip of the bearing portion 26E is in contact with the brake pedal 20 (a dotted line position shown in FIG. 4). Then, the bearing portion 26E is rotated clockwise with respect to the adjuster 26F.

  By rotating the bearing portion 26E, the bearing portion 26E and the adjuster 26F are fitted and fixed, and at the same time, the bearing portion 26E moves with respect to the adjuster 26F by a return amount x2 in the direction opposite to the A direction. At this time, it is possible to cope with various arrangements of the sensor units 26A by adjusting the return amount x2.

(Effects of the first embodiment)
According to the first embodiment described above, since the pitches of the thread 260E and the thread 261F are different, the pitch at which the thread 260E and the thread 261F are fitted is 1 in the present embodiment. Therefore, when mounting the bearing portion 26E, positioning can be performed with a dimensional accuracy equal to or greater than the thread pitch.

  In addition, the pitch of the thread 260E and the thread 261F, and the return amount x2 can be set to arbitrary values.

  Further, the brake lamp switch 26 is not limited to a non-contact type non-contact switch, and a contact type switch may be used.

  The adjuster 26F and the bearing portion 26E can be improved in accuracy and strength using a material such as modified PPE (modified-PolyPhenyleneEther) or PBO (Poly-p-Phenylene Benzobisoxazole) having high strength.

Next, the operator inserts the bearing portion 30 into the main body portion 311 of the adjuster 31 and pushes it in until the lower surface thereof contacts the brake pedal 20. At this time, since the bearing portion 30 and the adjuster 31 are both made of resin and the screw thread 301 has a tie wrap structure, the bearing portion 30 can be easily inserted into the adjuster 31.

  When the bearing portion 30 has been inserted into the adjuster 31, as shown in FIG. 12, the thread 312 and the thread 301 are engaged, and the bearing 30 and the adjuster 31 are fixed, as shown in FIGS. become.
