Self-locking and lever principle-based vehicle electrical control/manual double-purpose safety hammer

Abstract

The invention discloses a self-locking and lever principle-based vehicle electrical control / manual double-purpose safety hammer, which belongs to the technical field of an automobile safety device. The self-locking and lever principle-based vehicle electrical control / manual double-purpose safety hammer is characterized in that: the hammer head is a conical hammer head of which the bottom surface is in contact with a compression spring; the hammer head is arranged in a circular guide cavity; a self-locking component force device is arranged on a mounting bracket of the shell through a pin shaft; a short arm end is in contact with a conical surface of the hammer head, and a long arm end is in contact with an electromagnetic iron core; a pull ring is arranged at the lower end of the self-locking component force device; a one-key type centralized control safety hammer parallel electrical control network can be constructed; after a starting switch is started or the pull ring is manually pulled, the self-locking component force device is unlocked and the hammer head bounces out along the circular guide cavity to smash glass; and under the condition that a safety cover is damaged in a mistaking way, an alarm switch is closed, and a buzzer sends an alarm. The self-locking and lever principle-based vehicle electrical control / manual double-purpose safety hammer has the effects and benefits of electrical control and manual operation, high reliability, capability of automatically smashing glass, convenience for passengers to escape, integrated shell, simple structure, easiness for batch production and capability of being applied to school buses, buses, sightseeing buses, trains and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile safety devices, and relates to an emergency glass breaking device, in particular to a vehicle electric control / manual dual-purpose safety hammer based on self-locking and lever principles. Background technique [0002] The safety hammer widely used on the passenger car is usually hung on the side window place at present, takes off during use and realizes escape by breaking the glass by manpower. Through actual investigation, it is found that the traditional safety hammer can be removed manually, and most of it is lost after a long time; at the same time, the scene of the accident was chaotic, and the passengers were in a state of panic, unable to find the safety hammer, and could not accurately break the glass, resulting in an escape environment during the accident. The request cannot be met. Recently, with the widespread concern of school bus safety, some manufacturers have begun to try to us...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: aiming at the problem that the safety hammer on the traditional passenger car is often lost and the passengers cannot break the glass to escape in time when an accident occurs, to design an electric control / manual dual-purpose vehicle based on the principle of self-locking and lever The safety hammer can build a one-button centralized control safety hammer parallel electronic control network. In a critical situation, the driver can turn on the start switch and smash all the glass at the safety exit at the same time, which is convenient for passengers to escape; at the same time, in the event of a failure, passengers The safety cover can be destroyed by itself, and the safety hammer can be activated by pulling the pull ring to break the glass. The two control methods improve the reliability
