Abstract
The utility model provides a self-testing electronic scale for a vehicle. The electronic scale comprises a plurality of weight sensors and a processing module. The weight sensors are fixed in suspension positions respectively, each weight sensor comprises an elastomer, a resistance strain gauge, and a measuring circuit, the gravity of a vehicle frame acts on the elastomer, corresponding elastic deformation occurs to the elastomer, the elastic deformation is converted into the resistance change through the resistance strain gauge, and the resistance change is converted into an electrical signal through the measuring circuit; and the processing module is connected with the weight sensors, and performs amplification processing on the electrical signal, and the mass value of the vehicle frame is obtained and is output. According to the self-testing electronic scale for the vehicle provided by the utility model, the weight sensors are mounted on the vehicle, and the mass value of the vehicle frame is measured by the electronic scale itself, facilitating a driver to know load information of the vehicle frame in real time.
Description
[technical field]
The utility model relates to a kind of automatic electron scale for car, and particularly a kind of driver of convenience understands the automatic electron scale for car of vehicle frame weight information in real time.
[background technology]
Overweight meeting damages the suspension parts such as car damping; Braking distance can increase, and security reduces; The heavyduty tire wearing and tearing; Increase added burden for engine, variator and kinematic train, cause excessive wear, reduced the serviceable life of related components.Whether overweight, platform scale is divided into mechanical type, dynamo-electric convolution and electronic type 3 classes by 26S Proteasome Structure and Function if can understand automobile by platform scale, with mechanical type for basic model.The scale body of mechanical type and dynamo-electric convolution is placed in the underground foundation ditch, and scale surface and ground maintain an equal level.The scale body of electronic type be placed directly on the ground or frame on shallow hole, the scale surface is above the ground level, two ends are with the gradient, removable use claims again without the foundation ditch truck scale.The electronic type platform scale is the developing direction of truck scale, and the electronic type platform scale can form transition components one time by 4～6 sensors according to weighing.Usually with on 4 angles of 4 sensor locations below bearing platform, consist of a sensing system.For making 4 sensors share a power supply and improving antijamming capability, 4 groups of electric bridges are connected into parallel way.Use keyboard operation during the metering of electronic type platform scale; have the functions such as automatic zero set (AZS), power-failure protecting (memory contents does not disappear at the appointed time), overload warning, and the printable value of weighing, date and the moment, number of times, license number, gross weight, tare weight, net weight etc.It can not only be with pin-point accuracy, but also has the functions such as data processing, computing.
But because the installation of platform scale need to be selected the place, automobile is weighed and need to the infield of platform scale, can't be allowed the user understand the load-carrying of automobile whenever and wherever possible.
[summary of the invention]
Fundamental purpose of the present utility model is to provide a kind of driver of convenience to understand in real time the automatic electron scale for car of vehicle frame weight information.
