Embodiment 1

[0117] Figure 1A and 1B is a view showing an operation pedal device 10 according to one embodiment of the present invention for a commonly used vehicle brake. Figure 1A shows the operation pedal 16 in a state of being depressed to the middle point of the depression stroke, Figure 1B Another state in which the operating pedal 16 is further depressed to the end of the depression stroke is shown. Vehicle operating pedal device 10 represents that the present invention is applied to Figure 21A and 21B The situation of operating the pedal device 200 is shown. The operating pedal 16 is formed with a sensor mounting hole 28 for mounting a load sensor 30 therein.

[0118] Like the load sensor 204 described above, the load sensor 30 has a wire harness 56 having an end coupled to a connector 58 through which the wire harness 56 is connected to a control circuit portion of the vehicle. The operating pedal device 10 corresponds to an operating device in the claims, and the operati...

Embodiment 2

[0163] Figures 9A and 9B are corresponding to Figure 1A and 1B view. FIG. 9A shows a state where the depressing stroke is at its intermediate point, and FIG. 9B shows another state where the depressing stroke is at its final stage. The vehicle operating pedal device 80 includes an intermediate lever 82 through which the operating force is transmitted from the operating pedal 16 to the operating lever 22 .

[0164] The middle lever 82 has one longitudinal end pivotally mounted on the pedal bracket 12 by means of a support pin 84 extending parallel to the bracket shaft 14, and is pivotally connected to the operating pedal 16 via a link 86. the longitudinal middle. This allows the intermediate lever 82 to mechanically pivot about the support pin 84 accompanying the depression of the operating pedal 16 . The connecting link 86 has two longitudinal ends respectively connected to the operating pedal 16 and the intermediate rod 82 via a pair of connecting pins 88 and 90 extending ...

Embodiment 3

[0168] Figure 10 The load sensor 100 shown has the same basic structure as the above-described embodiments and includes a strain trigger element 32 , a housing member 34 and a shaft member 36 . However, the four strain resistance elements 102a to 102d are arranged at positions different from those in the above-described embodiment. That is, the four strain resistance elements 102a to 102d are arranged in four areas bounded by the neutral plane S and another plane that passes through the axis of the strain trigger element 32 perpendicular to the neutral plane S, that is, the centerline O. The sexual plane S is in a symmetrical positional relationship. More specifically, four strain-resistive elements 102a-102d are positioned at four locations on the strain-triggering element 32 at (intervals of) approximately 90° from the centerline O (axis Q) of the sensor and at approximately 45° The angle of the two straight lines passing through the neutral plane S intersects. The centr...

Abstract

A load-sensor-equipped vehicle operating pedal device includes a load sensor ( 30 ) having a case member ( 34 ) formed with a pair of mounting wall portions ( 62 a, 62 b) converged in a convex shape at a predetermined apex angle alpha. The pair of mounting wall portions ( 62 a, 62 b) are held in surface contact with a pair of rest surfaces ( 28 a, 28 b), formed in a sensor-mounting hole ( 28 ) in a fixed and positioned state. Thus, even if a direction of an input load (reactive force), applied to a clevis pin ( 26 ) varies with an operating pedal 16 being progressively depressed, the pair of rest surfaces ( 28 a, 28 b) always bear the input load via the pair of mounting wall portions ( 62 a, 62 b). This suppresses the case member ( 34 ) from flexure deforming due to stress concentration.; As a result, positional displacement of a sensor is prevented regardless of a variation in the direction of the input load, improving detecting precision.

Description

[0001] This application is based on Japanese Patent Application No. 2007-106377 and Japanese Patent Application No. 2007-330823, and the contents thereof are incorporated herein. technical field [0002] The present invention relates to an operating device such as a vehicle operating pedal device and the like, and more particularly to an improvement in an operating device equipped with a load sensor having a load sensor for electrically detecting (electrically detecting) an operating force. Background technique [0003] Hitherto there is known a type of operating device equipped with a load sensor comprising (a) a displaceably operated operating member; (b) a reaction member; (c) at least one pivot (rotation) connection ; and (d) load cells. The operation force of the operation member is transmitted to the reaction member, and a reaction force acts on the reaction member at a rate / magnitude (rate) depending on the operation force causing (the reaction force). At least one p...
