Description

A kind of electronic digital swivel chair that can weigh in

Technical field

The utility model relates to a kind of equipment of weighing in, and especially is arranged on the weighing-appliance on the swivel chair.

Background technology

Staff's major part before the much domestic and international companies of China, enterprises and institutions, white collar clan, the especially computer desks is all being used swivel chair at present, and this swivel chair is easy to use, moves rapid, just adjustable.We can say One's name is legion, style has hundreds of, but also there is not to provide for the user at any time at present the swivel chair of body wt, if a kind of such swivel chair is arranged, at any time weighing body wt, impel user's increase activity or weight reducing exercise, so just can improve user's body health level, the quality of making the life better.

Summary of the invention

According to background technology, the purpose of this utility model is to avoid above-mentioned deficiency, a kind of maintenance swivel chair original function is provided, and install body weight sensor additional at the swivel chair base position of commonly using, on the right handrail of swivel chair, be provided with show and speech play partly and the electronic digital swivel chair that can weigh in of electronic compartment.

In order to realize above-mentioned functions, the utility model is achieved through the following technical solutions:

A kind of electronic digital swivel chair that can weigh in, mainly by swivel chair chair body (1), swivel chair base (2) and chair armrest (3) are formed, and wherein: swivel chair chair body (1) is for commonly using the chair body of swivel chair; Swivel chair base (2) is by deformable bedplate (21), body weight sensor (22) and Connection Block (25) are formed, wherein bedplate (21) is undertaken hinged with Connection Block (25) by slide hinged point (23), bedplate (21) contacts with body weight sensor (22) partial face (24), body weight sensor (22) is mutually permanently connected with Connection Block (25), and Connection Block (25) is connected with the swivel chair supporting mechanism (11) of swivel chair chair body (1); The right handrail (31) of chair armrest (3) keeps same contour structures with left handrail (32), upper surface at right handrail (31) is provided with LCDs (33), the button (34) of weighing, voice broadcast button (35), in the inboard of right handrail (33) power switch (36) is set, speech play hole (37) and electronic compartment (38), device has sensing circuit, amplifier, wave filter, analog-digital converter, CPU, battery and connecting circuit in electronic compartment (38).

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, the utility model can make things convenient for user's power-on switch when wanting to weigh in to show weight data in 2 seconds on LCDs, and error is no more than 0.5%, finishes the back powered-down; Also can click the voice broadcast button, enter for weight data by voice.

2, the utility model is for avoiding palm or arm false touch shift knob, with the side of shift knob device at chair armrest.Under the situation of power-on not, other buttons and LCDs can not be affected on the surface of handrail.

3, the utility model is simple in structure, makes easily, and starting material are easily purchased, and are cheap, and working service and repairing are simple and easy.

Embodiment

Illustrate by Fig. 1, a kind of electronic digital swivel chair that can weigh in, mainly by swivel chair chair body 1, swivel chair base 2 and chair armrest 3 are formed, and wherein: swivel chair chair body 1 is for commonly using the chair body of swivel chair; Swivel chair base 2 is by deformable bedplate 21, body weight sensor 22 and Connection Block 25 are formed, wherein bedplate 21 is undertaken hinged with Connection Block 25 by slide hinged point 23, bedplate 21 contacts with body weight sensor 22 partial face 24, body weight sensor 22 is mutually permanently connected with Connection Block 25, and Connection Block 25 is connected with the swivel chair supporting mechanism 11 of swivel chair chair body 1; The right handrail 31 of chair armrest 3 keeps same contour structures with left handrail 32, upper surface at right handrail 31 is provided with LCDs 33, the button 34 of weighing, voice broadcast button 35, in the inboard of right handrail 33 power switch 36 is set, speech play hole 37 and electronic compartment 38, device has sensing circuit, amplifier, wave filter, analog-digital converter, CPU, battery and connecting circuit in electronic compartment 38.

Other knows, the purpose of this utility model is to improve the deficiency of commonly using the swivel chair function, installing electronic digital weighing scales parts additional in the armrest portion of commonly using swivel chair forms, both feet while built on stilts during use, open switch, will accurately demonstrate body wt on the LCDs after 2 seconds, simultaneously also can the voice count off, error is in 0.5%.

Body weight sensor 22 can adopt piezoelectric crystal, also can adopt compression spring, they all possess the stress-strain relation of self structure, when human body weight acts on the bedplate 21, bedplate 21 produces amount of deflection deformation, contact with body weight sensor 22 partial face 24 by bedplate 21, load on the body weight sensor 22, make body weight sensor 22 produce deformation, certain deformation is corresponding with certain stress, power is converted to the simulating signal of voltage or electric current, after amplification and Filtering Processing, be converted to digital signal by the A/D processor, digital signal is by the central processor CPU calculation process, and periphery institute need function and various interface circuit also be electrically connected successively with single-chip microcomputer, show also and can read and played data with digital form by display screen at last by voice module.

By Fig. 2 the utility model circuit block diagram is shown.
