Automobile horn pressing force control device, automobile horn pressing force control method and automobile

Abstract

The invention provides an automobile horn pressing force control device. An automobile horn comprises a press button switch comprising moving and stationary contact bodies which are oppositely arranged; wherein a springback device is arranged between the moving and stationary contact bodies, and therefore the moving and stationary contact bodies are arranged at an certain interval through the springback device; and the moving contact body can be electrically connected to the stationary contact body through pressing operation. The pressing force control device comprises a pressing force detection device, an electromagnet and a control unit, wherein the pressing force detection device is fixed on the moving contact body and / or the stationary contact body and is used for detecting pressing force applied on the moving contact body; the electromagnet is fixed on the moving contact body or the stationary contact body and can generate magnetic force on the moving contact body, and the magnetic force enables the moving contact body to move close to the static contact body; the input end of the control unit is connected with the pressing force detection device, the output end is connected with the electromagnet, the control unit controls the magnetic force of the electromagnet according to detected pressing force, and therefore a user can be assisted in pressing the horn, horn pressing force suitable for the hand touch of the user can be realized through adjustment, and the problem that the horn is hard to press is solved.

Description

technical field [0001] The invention belongs to the field of car horns, and in particular relates to a car horn pressing force control device and method and a car. Background technique [0002] At present, most car horns are triggered by pressing the button switch of the horn. The button switch usually includes a moving contact body and a static contact body arranged oppositely. A certain distance is arranged between the moving contact body and the static contact body. The body is electrically connected with the speaker. Pressing the movable contact body can make the movable contact body move towards the static contact body, contact the static contact body, and electrically connect with it, thereby connecting the horn circuit and triggering its ringing. Yet the button switch of the automobile horn of prior art is all more difficult to press, and this is because a rebound device is usually provided with between the dynamic and static contacts to keep the distance between the...
