Abstract

An onboard weighing device comprises a vehicle body, a weighing sensor mounted on the vehicle body, a hook mounted at the lower end of the weighing sensor, and an electronic scale module electrically connected with the weighing sensor. During the operation of the weighing device, an object is suspended on the hook; the hook acts on the weighing sensor; the weighing sensor converts the gravity into a voltage or current analog signal, which is converted to a digital signal by an A/D processor after amplification and filtering processing; the digital signal is transmitted to the electronic scale module; and the central processing unit (CPU) of the electronic scale module processes the signal and displays the result on a display and a sound device. The onboard weighing device is convenient in weighing objects during shopping so as to safeguard the rights of consumers.

Description

A kind of vehicle-mounted weighing device

Technical field

The utility model relates to a kind of weighing device, particularly a kind of vehicle-mounted weighing device.

Background technology

At present people mostly can be with the shopping of going on a journey of the mode of electric motor car or motorcycle; but because the China market order is unsound; there is fraud in a lot of retailers; the article short weight; do shopping inconvenient and carry the instrument of weighing; the back finds have shortage in weight also late even go home, so a lot of consumer has no way out to pedlar's this fraud, consumers' rights and interests can not effectively be protected.

Summary of the invention

The purpose of this utility model is to remedy the deficiency of above-mentioned existing situation, has proposed a kind of vehicle-mounted weighing device, has characteristics simple in structure, easy to use.

The technical solution of the utility model is achieved in that a kind of vehicle-mounted weighing device, comprise a LOAD CELLS, LOAD CELLS is installed on the car body by the load-bearing line, the LOAD CELLS lower end is equipped with hook, LOAD CELLS is connected by electric wire with the electronic scales module, and the electronic scales module is installed in the panel board on the car body, and the electronic scale module is connected with storage battery electric wire on the car body, offer display window and power switch on the panel board, storage battery is connected with electronic scale module electric wire through power switch.

Described car body can be electric motor car car body or body of motor cycle.

Described LOAD CELLS is installed on the position that car body is convenient to weigh, as: handlebar, Che Liangchu.

Described power switch offers three gears, and the storage battery power supply shelves, dry cell power supply shelves and the power supply that are respectively on the car body disconnect shelves.

Described electronic scales module, comprise a mounting circuit boards and be installed on single-chip microcomputer on the circuit board, high precision linear amplifier, and the A/D converter that constitutes of voltage/frequency transducer, and display that is connected with circuit board and sound-producing device, supply and accessory circuit thereof.

Because the utility model has been installed weighing device on car body, make people when the trip shopping, be convenient to the weighing commodity weight, be convenient to protect consumer's rights and interests.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of electronic scale module 4 of the present utility model.

Embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are elaborated.

With reference to Fig. 1,2, the utility model comprises LOAD CELLS 1, LOAD CELLS 1 is installed on the car body 2 by load-bearing line 14, LOAD CELLS 1 lower end is equipped with hook 3, LOAD CELLS 1 and electronic scales module 4 are connected by electric wire, electronic scales module 4 is installed in the panel board 5 on the car body 2, electronic scale module 4 is connected with storage battery 12 electric wires on the car body 2, and on panel board 5, offer display window 6, offer power switch 11 on the panel board 5 simultaneously, storage battery 12 is connected with electronic scale module 4 electric wires through power switch 11.

Described car body 2 not only can be the electric motor car car body, also can be body of motor cycle.

Described LOAD CELLS 1 should be installed on the position that car body 2 is convenient to weigh, as: handlebar, Che Liangchu.

Described power switch 11 offers three gears, and the storage battery 12 power supply shelves, dry cell 13 power supply shelves and the power supply that are respectively on the car body 2 disconnect shelves.

With reference to Fig. 2, described electronic scales module 4, comprise a mounting circuit boards 7 and be installed on single-chip microcomputer on the circuit board 7, high precision linear amplifier, and the A/D converter 8 that constitutes of voltage/frequency transducer, and display 9 that is connected with circuit board and sound-producing device 10, supply 13 and accessory circuit thereof.

During work, turn on the power switch 11, article are hung on the hook 3, hook 3 acts on the LOAD CELLS 1, and LOAD CELLS 1 is converted to the analog signal of voltage or electric current with gravity, conducts to electronic scales module 4 by electric wire.Analog signal is converted to digital signal by A/D processor 8 after amplification and Filtering Processing in electronic scales module 4, and by central processing unit (CPU) calculation process, the result outputs on display 9 and the sound-producing device 10.

Because described LOAD CELLS 1 is installed on the position that car body 2 is convenient to weigh, as: handlebar, Che Liangchu, so weigh conveniently, can not cause damage, and adopt the dual power supply pattern the use of car body, use convenient.
