Alarm device for escape hatch

Abstract

An alarm device for an escape hatch is composed of an emergency handle (1), a lock shaft (3) and a support assembly (5). A spring bolt (2) is fixedly installed in the middle of the lock shaft (3). The emergency handle (1) is fixedly connected to the top end of the lock shaft (3). The lock shaft (3) is movably connected to the support assembly (5). A lock groove (6) is formed in the support assembly (5). The alarm device is characterized in that a microswitch (4) is fixedly installed on the support assembly (5), installed on one side of the lock shaft (3) and located below the spring bolt (2), and the emergency handle (1) is pulled to drive the lock shaft (3) to rotate so that the spring bolt (2) can enter the lock groove (6) and press down the microswitch (4). The alarm device is simple in structure and convenient and rapid to install, an automobile driver can quite visually recognize whether the escape hatch is opened or closed through a signal lamp, and potential safety hazards during driving are eliminated.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an alarm device for a safety roof window. Background technique [0002] At present, the safety roof window installed on the roof of the passenger car, in case of an emergency, pulls off the emergency handle protective cover, turns the emergency handle, and pushes the roof window outward to form an escape passage, thereby realizing escape; in actual use, the safety roof The window is often used as an inspection port. The vehicle maintenance personnel turn the emergency handle to access the vehicle on the roof from the opening of the roof window. In this way, the maintenance personnel often forget to restore the emergency handle to the original position after entering the vehicle from the roof after inspection. If the rear locking mechanism of the roof window is not locked at this time, the roof window will bounce up and down while the vehicle is running, which will easily da...

[0002] At present, the safety roof window installed on the roof of the passenger car, in case of an emergency, pulls off the emergency handle protective cover, turns the emergency handle, and pushes the roof window outward to form an escape passage, thereby realizing escape; in actual use, the safety roof The window is often used as an inspection port. The vehicle maintenance personnel turn the emergency handle to access the vehicle on the roof from the opening of the roof window. In this way, the maintenance personnel often forget to restore the emergency handle to the original position after entering the vehicle from the roof after inspection. If the rear locking mechanism of the roof window is not locked at this time, the roof window will bounce up and down while the vehicle is running. In the long run, the roof window parts will be easily damaged, and in severe cases, the roof window may fall off from the vehicle body.

At present, the driver mainly relies on the driver to visually determine whether the rear locking mechanism of the roof window is locked, resulting in complicated operation, increasing the labor intensity of the driver, and posing serious safety hazards.
