Safety reminding device for exit of underground parking lot

Abstract

The invention discloses a safety reminding device for an exit of an underground parking lot. The safety reminding device comprises a trigger mechanism, wherein the trigger mechanism comprises a plurality of deceleration strips, the plurality of deceleration strips are arranged in the exit of the parking lot, the deceleration strip comprises a supporting plate and a pressing plate, the pressing plate is arranged above the supporting plate, an air cavity is formed between the pressing plate and the supporting plate, a sealed pressure cavity is formed among the pressing plate, the supporting plate and the air cavity, the supporting plate is fixedly installed on the ground, a sealed air cavity is formed between the supporting plate and the ground, a reset piece is arranged in the air cavity, and a plurality of air holes are formed in the supporting plate. In the invention, when a vehicle drives out of the underground parking lot, an alarm mechanism makes a sound to remind external pedestrians or vehicles that the vehicle immediately drives out of the parking lot so as to pay attention to deceleration and avoidance, and no power element is needed in the whole process, so that extra power resources are not needed, the device can be used under any condition, and the use cost of a user can also be reduced.

Description

technical field [0001] The invention belongs to the technical field of safety reminding devices, in particular to a safety reminding device used for the exit of an underground parking lot. Background technique [0002] In an urban area with many vehicles, a parking lot with high parking efficiency is required. Therefore, in addition to the gondola-type three-dimensional parking lot in which the vehicle is hoisted into the building and stored therein, there is also an underground parking lot in which the parking space for the vehicle is layered under the basement of the building. The entrance and exit passages of underground parking lots are generally narrow, which causes great inconvenience to vehicles entering and exiting, especially the narrow passages are mostly with bends, which makes the driver's vision smaller, which makes it easier for vehicles to enter and exit the parking lot than to go straight. Vehicles collide and scratch, and even cause safety accidents to pass...

AI Technical Summary

Problems solved by technology

The entrance and exit passages of underground parking lots are generally narrow, which causes great inconvenience to vehicles entering and exiting, especially the narrow passages are mostly with bends, which makes the driver's vision smaller, which makes it easier for vehicles to enter and exit the parking lot than to go straight. Vehicles collide and scratch, and even cause safety accidents to passing pedestrians

[0003] Traditional intersections allow drivers to obtain a wider field of view by setting convex mirrors, but the field of view that can be improved by this method is limited, and there are still large blind spots in the field of vision; with the development of technology, reminder devices using sensors have gradually appeared, using sensors to perceive Whether there is a vehicle passing by, and then feed back to the alarm to achieve the alarm reminder effect; in this safety reminder system, both the sensor and the alarm are power components, which will not be used when the power is accidentally cut off, and will have an additional effect when used. power resources, the cost of use is relatively high
