Abstract
The utility model discloses an automobile safety seat based on a magneto-rheological damper. The automobile safety seat comprises a seat body and a support column mounted below the seat body. A pressure sensor, the magneto-rheological damper and a spring is mounted in parallel between the support column and an automobile bottom. The pressure sensor is connected with an input end of a single-chip microcomputer through a signal processor. An output end of the single-chip microcomputer is connected with a controllable power supply which is connected with the magneto-rheological damper. The automobile safety seat is high in intelligence level, damping of the damper can be reasonably automatically adjusted according to weight of a driver and automobile vibration intensity during driving, and accordingly damper output force is changed, and riding comfortableness of the seat is improved.
Description
Technical field
The utility model belongs to the auto parts and components field, is specifically related to a kind of automotive seat.
Background technology
Along with national economy develop rapidly, freeway net all-round construction and living standard greatly improve, automobile be dissolved into gradually people work the life among, become the indispensable vehicle, people propose higher requirement to ride of vehicle and safety.Traditional automotive seat adopt common damper, because of its dumping force constant, so the extent of vibration in the time of can not be according to the body weight of passenger and running car reasonably changes damping, more weak and the less personnel of body weight of feasible vibration arrive in seat and cross " firmly ", and to big with the automobile vibration degree, the passenger body weight is bigger, feels that again seat crosses " soft ", greatly reduces the travelling comfort of seat thus.And the human discomfort that the vibration of automobile brings to the people is general, and especially on present lorry and passenger vehicle, its drawback is particularly outstanding.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is, a kind of safety chair seats of car that can improve seat comfort based on MR damper is provided.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of safety chair seats of car based on MR damper, comprise seat and pillar stiffener, pillar stiffener is installed in under-seat, between pillar stiffener and the automobile bottom surface pressure sensor, MR damper and spring are installed side by side, pressure sensor links to each other with the input end of micro controller system by signal processor, the mouth of micro controller system links to each other with controllable electric power, and controllable electric power links to each other with MR damper.
The utility model also has following technical characterstic:
Described pressure sensor adopts SM5651-003D-3S type pressure sensor.
Described micro controller system adopts the STC189C51 micro controller system.
Intelligent degree height of the present utility model, the damping of the intensity adjusting damper automatically and reasonably that vibrates in the time of can be according to the body weight size of passenger, running car changes the size of damper power output with this, improves the travelling comfort of seat greatly.
Description of drawings
Fig. 1 is an installation site of the present utility model scheme drawing.
Fig. 2 is a control part annexation scheme drawing of the present utility model.
Fig. 3 is the integral structure scheme drawing of MR damper.
The implication of each label is among the figure: 1-seat, 2-pillar stiffener, 3-automobile bottom surface, the 4-pressure sensor, 5-MR damper, 6-spring, the 7-signal processor, 8-micro controller system, 9-controllable electric power, the 51-clutch release slave cylinder, 52-damp channel, 53-magnetic flow liquid, the 54-excitation coil, the 55-magnetic flux, 56-piston, 57-piston rod.
Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.
The specific embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as depicted in figs. 1 and 2, a kind of safety chair seats of car based on MR damper, comprise seat 1 and pillar stiffener 2, pillar stiffener 2 is installed in seat 1 below, and pressure sensor 4, MR damper 5 and spring 6 are installed between pillar stiffener 2 and the automobile bottom surface 3 side by side, and pressure sensor 4 links to each other with the input end of micro controller system 8 by signal processor 7, the mouth of micro controller system 8 links to each other with controllable electric power 9, and controllable electric power 9 links to each other with MR damper 5.
Controllable electric power 9 adopts the non-maintaining type storage battery.The non-maintaining type storage battery is to make with lead-calcium alloy, because storage battery has adopted lead-calcium alloy to make the grid frame, so the water decomposition amount that produces during charging is few, water evaporation quantity is also low, adds that shell adopts hermetically-sealed construction, and the sulfuric acid gas that discharges also seldom, so it is compared with traditional storage battery, do not have and need add any liquid, butted line pile crown, advantages such as electric weight storage time length.
Working process of the present utility model is as follows:
In the vehicle traveling process, owing to road excitation is vibrated, relative vibration takes place with clutch release slave cylinder 51 in piston 56, because the vibration intensity difference, its pressure is also different.Pressure sensor 4 on each safety seat, the pressure variation that seat 1 is born passes to signal processor 7 in real time, is to pass to micro controller system 8 after the digital signal by signal processor 7 with analog signal conversion, excessive or kick the beam and running car time vibration when relatively more violent when the passenger body weight, the pressure signal that pressure sensor 4 is detected changes strong, signal processor 7 receives this strong signal and is converted to digital signal and passes to micro controller system 8, after making judgement, 8 pairs of pressure signals variations of micro controller system send control signal, the increase of the electric current of control controllable electric power 9 outputs, control the electric current that is carried in the MR damper 5 on the excitation coil 54 with this and increase, the power output of MR damper 5 is increased; When seat 1 vibration tends towards stability, the pressure signal that pressure sensor 4 detects changes and weakens, micro controller system 8 is controlled controllable electric power 9 again, make the electric current of controllable electric power 9 reduce, finally reduce the power output of MR damper, control makes the vibration of seat 1 reach the most reasonable effectiveness in vibration suppression so repeatedly, improves ride of vehicle.
