Abstract
The utility model discloses an involute type lever unlocking mechanism which is composed of a transmission shaft, a first-order lever, a first shaft shoulder rivet, a casing pipe, an involute face, a second-order lever, a second shaft shoulder rivet and a fixing support. One end of the first-order lever is fixedly connected with the transmission shaft, the other end of the first-order lever is pivoted to the casing pipe through the first shaft shoulder rivet, the second-order lever is hinged to an angle regulator body through the fixing support and the second shaft shoulder rivet, the upper section of the second-order lever is provided with the involute face, the casing pipe arranged at the head end of the first-order lever makes contact with the involute face, and the force application direction of the involute face of the second-order lever to the casing pipe is always perpendicular to the center line of the first-order lever. In the movement process of the involute type lever unlocking mechanism, the force application direction of the involute face of the second-order lever to the casing pipe is always perpendicular to the center line of the first-order lever, and the smallest force is applied, so that the first-order lever unlocking moment of force is maximized, and operation comfort is improved.
Description
Technical field
The utility model relates to a kind of evolvent type lever release mechanism.
Background technology
Existing automotive seat exist recliner unlocking operation power to be worth excessive problem, had a strong impact on the traveling comfort of operation, and the layout of mechanism are very subject to the restriction in space herein.
Summary of the invention
The purpose of this utility model is to be worth excessive problem in order to solve recliner unlocking operation power, and a kind of evolvent type lever release mechanism is provided.
The utility model is by transmission shaft, single order lever, the first shaft shoulder rivet, sleeve pipe, involute face, second order lever, the second shaft shoulder rivet and fixed support form, one end of single order lever is fixedly connected with transmission shaft, the other end of single order lever is by the first shaft shoulder rivet pivot joint sleeve pipe, second order lever is hinged on recliner body by the second shaft shoulder rivet by fixed support, the epimere of second order lever has involute face, the head end sleeve pipe of single order lever contacts with involute face, the involute of second order lever is in the face of the application of force direction of sleeve pipe is all the time perpendicular to the line of centers of single order lever.
Working process of the present utility model:
Pull second order lever, the involute face of second order lever is pressed and is touched sleeve pipe, by the first shaft shoulder rivet, drives single order lever to rotate, and single order lever drives transmission shaft rotates, and then to recliner release; In mechanism kinematic process, the involute of second order lever is in the face of the application of force direction of sleeve pipe is all the time perpendicular to the line of centers of single order lever.
The beneficial effects of the utility model:
The utility model is in mechanism kinematic process, and the involute of second order lever is faced the application of force direction of sleeve pipe all the time perpendicular to the line of centers of single order lever, imposes minimum power, and the moment of single order lever release is maximized, and has improved the traveling comfort of operation.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is lateral plan of the present utility model.
The specific embodiment
Refer to shown in Fig. 1 and Fig. 2, the present embodiment is by transmission shaft 1, single order lever 2, the first shaft shoulder rivet 3, sleeve pipe 4, involute face 5, second order lever 6, the second shaft shoulder rivet 7 and fixed support 8 form, one end of single order lever 2 is fixedly connected with transmission shaft 1, the other end of single order lever 2 is by the first shaft shoulder rivet 3 pivot joint sleeve pipes 4, second order lever 6 is hinged on recliner body A by the second shaft shoulder rivet 7 by fixed support 8, the epimere of second order lever 6 has involute face 5, the head end sleeve pipe 4 of single order lever 2 contacts with involute face 5, the application of force direction of 5 pairs of sleeve pipes 4 of involute face of second order lever 6 is all the time perpendicular to the line of centers of single order lever 2.
The working process of the present embodiment:
Pull second order lever 6, the involute face 5 of second order lever 6 is pressed and is touched sleeve pipe 4, by the first shaft shoulder rivet 3, drives single order lever 2 to rotate, and single order lever 2 drives transmission shaft 1 to rotate, and then to recliner release; In mechanism kinematic process, the application of force direction of 5 pairs of sleeve pipes 4 of involute face of second order lever 6 is all the time perpendicular to the line of centers of single order lever 2.
The present embodiment is in mechanism kinematic process, and the application of force direction of 5 pairs of sleeve pipes 4 of involute face of second order lever 6, all the time perpendicular to the line of centers of single order lever 2, imposes minimum power, and the moment of single order lever 2 releases is maximized, and has improved the traveling comfort of operation.
