Abstract
The utility model relates to an odometer, in particular to a speedometer for an engineering truck, comprising a rear shell. A front cover is clamped in front of the rear shell, and a glass panel is fixed in the front cover through a lining. A circuit board is fixed in the rear shell, and a singlechip is arranged on the circuit board. The singlechip is connected with a stepping motor on the circuit board, and the stepping motor is connected with a pointer on a dial below the glass panel. Compared with the prior art, the speedometer for the engineering truck has the characteristics of reasonable design, simple structure, low manufacture cost, stable and accurate indication and the like.
Description
Technical field
The utility model relates to a kind of mileometer, and a kind of engineering truck speedometer specifically is provided.
Background technology
The speedometer of the speedometer under the prior art, especially engineering truck, it is all moving-magnetic type, to the cutting speed of the magnet magnetic line of force, feeds back to panel board, and then is characterized by the speed of a motor vehicle and the mileage number of vehicle during promptly by vehicle movement.The mileometer of this structure, it is owing to be subjected to influence of magnetic field, the indication pointer can shake, indicate forbidden, weak point such as instability.
Summary of the invention
The utility model is at above deficiency, provide a kind of reasonable in design, simple in structure, cost of manufacture is low, the indication stable and accurate engineering truck speedometer.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of engineering truck speedometer, comprise back cover, described back cover the place ahead fixes protecgulum, be fixed with face glass by liner in the described protecgulum, described back cover internal fixation has wiring board, described wiring board is provided with single-chip microcomputer, and the stepper motor on the described single-chip microcomputer connection line version, described stepper motor connect the pointer on the dial of face glass below.
A kind of engineering truck speedometer of the present utility model, it adopts Single Chip Microcomputer (SCM) system, programming software drive controlling stepper motor drives the pointer of instrument, digital signal is transferred directly and accurately to the demonstration output of simulation, and, defectives such as the pointer shake that moving-magnet instrument exists, indication instability have been overcome by liquid crystal drive.Also can provide signal input requirement simultaneously by the client, carry out online programming, and this scheme also has three toggle switchs, and this a kind of table can be applicable to the input of 8 kinds of signals simultaneously, have reasonable in design, simple in structure, cost of manufacture is low, indicate stable and accurate advantage.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural front view of engineering truck speedometer;
Fig. 2 is a kind of structure vertical view of engineering truck speedometer.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
Shown in accompanying drawing 1,2, a kind of engineering truck speedometer, comprise back cover 1, described back cover 1 the place ahead fixes protecgulum 2, be fixed with face glass 4 by liner 3 in the described protecgulum 2, described back cover 1 internal fixation has wiring board 5, and described wiring board 5 is provided with single-chip microcomputer, stepper motor 6 on the described single-chip microcomputer connection line version 5, the pointer 8 that described stepper motor 6 connects on the face glass 4 below dials 7.
A kind of engineering truck speedometer of the present utility model, its with two tight fourths of the twelve Earthly Branches of screw on back cover 1, wiring board 5 is loaded in the back cover, driving switch is on wiring board 5, and liquid crystal display is supported by locating piece on wiring board 5 simultaneously, is lined with a scattering sheet under liquid crystal display, so that the led under the liquid crystal display can allow light be radiated under the liquid crystal display uniformly after lighting, return zero bar and be loaded on the wiring board 5, align, stretch out face glass 4 so that press with the hole on dial 7 and the face glass 4.
Driving switch is divided into three toggle switchs, has 8 kinds of speed ratios and selects.Liquid crystal display (accumulative mileage: 0～999999Km, error ± 1%, subtotal mileage: 0～999.9Km, error ± 1%), scattering sheet allows light be radiated at uniformly on the liquid crystal display, and time zero bar is used for the zero clearing of mileage short biography and short biography, switching totally show.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
