Problems solved by technology

However, such a device is costly and complicated to install, and it is not comprehensive enough to judge whether it is overweight only by detecting the weight of the people in the car, because the goods in the car also account for a large part of the total load of the car

Embodiment Construction

[0022] In order to make the technical means realized by the present invention, the purpose and effect achieved easy to understand and understand, the automobile self-detection overload reminder device provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 , figure 2 , image 3 As shown, the automobile self-detection overload prompting device of the present invention includes: an air shock absorber 1 , a PLC controller 2 , a buzzer 3 , and a pressure sensor 12 . Wherein, the pressure sensor 12 is installed on the air shock absorber 1, and the pressure sensor 12 is installed close to the compression position of the air shock absorber 1 when the car is fully loaded, so as to ensure that the air shock absorber 1 is compressed to this point when the air shock absorber 1 is compressed again. position, pressure signals can be generated such as image 3 shown. And when the normal situation or th...

Abstract

The invention discloses an automobile self-detection overload prompting device which comprises air dampers, a PLC (Programmable Logic Controller) and a buzzer. Each damper is provided with pressure sensors in a manner that the lower of an air damper compression position clings to the pressure sensors when an automobile is of full load, each pressure sensor is connected with an input port of the PLC, and an output port of the PLC is connected with the buzzer. The PLC comprises a misjudgment preventive device which further comprises a normally open switch, a timer and an output port, the output port of the misjudgment preventive device serves as the output port of the PLC, and the normally open switch is connected with the pressure sensors. Alarm is triggered when a pressure signal continues for 5 seconds. The overload prompting device of the invention includes misjudgment processing and prompting manners, and has the advantages of wider measurement range, low cost, convenient installation and reliable and flexible use.

Description

technical field [0001] The invention is an auxiliary device for automobiles, especially an auto-induction device for overload shock absorbers of automobiles. Background technique [0002] Automobile overloading has always been a very important issue in automobile driving safety. Overloading not only causes great damage to the car itself, but also affects the handling performance of the car, such as the braking reaction distance of the car. These all directly affect the driving safety of the driver. [0003] At present, the existing overload detection device is mainly installed in fixed places such as relevant checkpoints and toll stations, and detects whether the automobile is overweight when the automobile passes through. Through such external detection, although it can play a certain warning role, due to location restrictions, when the driver does not pass the toll booth or monitoring point, the driver cannot find out whether he is overweight. [0004] There is also a...
