Improved window breaking lifesaving device for cars

Abstract

The invention relates to an improved window breaking lifesaving device for cars. The window breaking device is mainly composed of a fixed shell, wherein a storage space is formed in the fixed shell, arotary shaft is arranged in the storage space in a transverse direction, both ends of the rotary shaft pass through rotary holes and are connected to power storage devices, a window breaking hammer is connected to the other end of a force bearing bar, two torsion springs are respectively arranged on the both ends, which are separated by the force bearing bar, of the rotary shaft, an excitation device is arranged in the shell, which is close to one end of the window breaking hammer, of the fixed shell, and wire holes penetrate through the fixed shell and are connected to the power storage devices on side surfaces. According to the improved window breaking lifesaving device, the power storage devices and the torsion springs are matched, so that force required by the operation of the windowbreaking hammer can be stored in advance; an upper cover is arranged outside, so that the device can be prevented from being accidentally triggered; and during operation, only the upper cover is opened, and the excitation device is pressed, so that the power storage devices can be released under the action of electromagnetic induction by using a power switch, the window breaking hammer can be driven to rotate for half cycle and then hit a car window by the torsion springs, and the window breaking lifesaving function is realized in the condition of falling into water or when other traffic accidents occur.

Description

technical field [0001] The invention relates to the field of vehicle lifesaving, in particular to an improved window lifesaving device for vehicles. Background technique [0002] At present, cars are used more and more frequently in people's daily life, and cars all use toughened glass, which is difficult to break. When a vehicle falls into water or a traffic accident occurs, the toughened glass that is not easy to break limits the escape of the passengers. Therefore, most vehicles are equipped with life-saving hammers and other devices, but the use of life-saving hammers requires great strength to break tempered glass, and life-saving hammers may not be effective in the face of emergencies or special groups of people. Contents of the invention [0003] The object of the present invention is to provide an improved vehicle window life-saving device to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the ...
