Abstract
The utility model relates to a projection scale, which comprises a scale body, a power supply, a controller, a strain transducer and a display. The strain transducer can convert the force born by the scale body into electrical signals which are output to the display after being processed by the microprocessor of the controller, the display comprises an optical projection device which can project data onto a screen or other objects to display the data, the display and a shell are movably connected with each other so that the display can rotate relative to the shell and can form a certain angle with the plane on which the shell is arranged, and the display is also provided with a liquid crystal display screen or an LED display screen. Since the weighing data can be projected to the screen or other objects through the optical projection device so as to be displayed, the display of the scale body can simultaneously display the weighing data. Since the display and the shell are connected movably, and the display can rotate relative to the shell, the projection angle of the optical projection device can be adjusted more conveniently. The utility model also has the advantages of simple structure, beautiful appearance and convenient use.
Description
Technical field
The utility model relates to electronic scales, and especially a kind of optical projection apparatus that has can project weighing result the projection scale that screen or other object show.
Background technology
Existing electronic scales generally all is to show weighing result by LCDs or LED display on the market, display screen is set directly on the shell of scale body usually, need people's both feet of weighing to stand on the scale pan of scale body case, observe weighing data by eyes then.At present, more than the scale body and the display screen thereof of this electron-like scale all less, can cause difficulty for the use of some special populations.For example, pregnant woman, overweight people or the people who has defective vision when the above two are weighed in, because the belly of self lordosis obstructs the view, add and are difficult for bending over observing, and are difficult to directly see the weight data on the scale body display screen of own underfooting; The latter may can not see the weighing result of underfooting clearly because eyesight is relatively poor when health is in erectility.
The utility model content
At the deficiency of above existing electronic scales, the purpose of this utility model provides a kind of optical projection apparatus that has, and weighing result can be projected the projection scale that screen or other object show.
The purpose of this utility model is achieved by the following technical solution:
The projection scale, comprise scale body, power supply, controller, strain transducer and display, power supply is electrically connected with controller and microprocessor, strain transducer and display, strain transducer converts the power of scale body load-bearing to electric signal, and output to display after the microprocessor processes by controller, described display comprises optical projection apparatus, and optical projection apparatus can project the display data presented on screen or other object and show.
As optimal technical scheme of the present utility model, described scale body comprises housing and display, is provided with flexible connection between display and the housing, makes display to rotate and have a certain degree with housing place planar shaped relative to housing.
As optimal technical scheme of the present utility model, also be provided with LCDs or LED display on the described display.
As optimal technical scheme of the present utility model, described controller comprises amplifying circuit, filtering circuit, analog/digital converter and microprocessor.
As optimal technical scheme of the present utility model, described microprocessor also is furnished with storer.
As optimal technical scheme of the present utility model, described scale body is provided with control panel.
The beneficial effects of the utility model are: with respect to prior art, the data projection of electronic scales display can be shown on screen or other object by optical projection apparatus, the display of scale body can show the data of weighing simultaneously; Be made as flexible connection between display and the housing, make display to rotate, be convenient to regulate the crevice projection angle of optical projection apparatus relative to housing.The utility model is simple in structure, good looking appearance, easy to use.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is a principle schematic of the present utility model;
Fig. 2 is a sectional structure synoptic diagram of the present utility model;
Fig. 3 is the structural representation of facing of the present utility model;
Fig. 4 is the principle schematic of the utility model optical projection apparatus.
Embodiment
As shown in Figure 1 to Figure 3, the projection scale, comprise the scale body and the power supply 4 that constitute by housing 1 and display 6, controller 3 and strain transducer 2, power supply 4 and controller 3 and microprocessor thereof, strain transducer 2 and display 6 are electrically connected, strain transducer 2 converts the power of scale body load-bearing to electric signal, and output to display 6 after the microprocessor processes by controller 3, display 6 comprises optical projection apparatus 5 and LCDs or LED display, optical projection apparatus 5 can show the data projection of weighing on screen or other object, the display screen of display 6 shows the data of weighing simultaneously.
In the present embodiment, be made as flexible connection between display 6 and the housing 1, make display 6 to rotate and have a certain degree, thereby be convenient to regulate the crevice projection angle of optical projection apparatus 5 relative to housing 1 with housing 1 place planar shaped.Controller 3 comprises amplifying circuit, filtering circuit, analog/digital converter and microprocessor, and microprocessor also is furnished with storer, and the housing 1 of scale body is provided with control panel.
As shown in Figure 4, optical projection apparatus 5 comprises catoptron 7, light source 8, concavees lens 9 and convex lens 10, and the weighing data that LCDs or LED display show simultaneously is arranged between concavees lens 9 and the convex lens 10 as image, after light source 8 irradiations, image 12 can be suitable for displaying on the objects displayed at screen or other.
