Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated further.
A kind of Intelligent massage armchair of accurately weighing as shown in Figures 1 to 5, comprise electric control gear, the mounting 1 of massage machine and support human body, massage machine is controlled by electric control gear, and (massage machine and electric control gear are prior art or the simple transformation to prior art, therefore not shown), electric control gear controls massage machine action and implements massage to human body, mounting 1 is provided with the leg supporting massage armchair, leg is generally 4, leg and earth surface, under the normality of not weighing, whole massage armchair is supported by leg, mounting 1 is also provided with weighing device, weighing device comprises the gravity sensor of human body weight, the driving mechanism that the push rod 5 of lifting mounting 1 and promotion push rod about 5 stretch, when needs are weighed to user, stretch out the upwards lifting of whole mounting 1 bottom mounting 1, whole massage armchair is supported by push rod 5.Gravity sensor is arranged on push rod 5, and push rod 5 is arranged on mounting 1, gravity sensor comprises elastic matrix 52 and resistance strain gage 54, resistance strain gage 54 to be fitted on elastic matrix 52 and and electric control gear electrical connection, elastic matrix 52 is provided with the touch part 53 protruded from outside push rod 5 bottom surface, when weighing, touch part 53 promotes elastic matrix 52 and produces elastic deformation and make resistance strain gage 54 produce deformation, the change in displacement that touch part 53 produces is converted to the resistance variations of resistance strain gage 54, and then generation current change, electric control gear calculates the weight of human body according to curent change, weight due to massage armchair is fixed value, human body weight is after removal.Driving mechanism comprises driving member 2 and power source, and driving member 2 connects push rod 5 by connecting rod 4, and mounting 1 is provided with the guide limiting driving member 2 motion track.
Driving member 2 is shaped as frame metal rack, and guide is four and is arranged in the bight of driving member 2, and push rod 5 is also four and installs the bight being connected to driving member 2 respectively.Guide is pull bar 3, the hinged mounting 1 in one end of pull bar 3, the hinged driving member 2 of the other end, and driving member 2 is arranged on mounting 1 by pull bar 3 suspension type, and power source drives driving member 2 to swing on mounting 1.Mounting 1 is provided with four support bars vertically stretched out upward 7, the upper end thereof of pull bar 3 is on support bar 7, lower end is hinged on driving member 2, driving member 2 is hung on support bar 7 by four pull bars 3, mounting 1 is provided with the guide slide 6 guiding push rod about 5 telescopic slide, push rod 5 is positioned at guide slide 6, and guiding slip is fixedly mounted on mounting 1, and the channeling direction of guide slide 6 is consistent with the direction of support bar 7.The hinged push rod 5 in connecting rod 4 one end, the coaxial hinged driving member 2 of the other end and guide, what is called is coaxially hinged refers to that connecting rod 4, driving member 2 and guide are movably hinged by same shipping and reselling on another market.Under the state of weighing, the pin joint of the pin joint of pull bar 3 and support bar 7, connecting rod 4 and driving member 2 is all positioned on the centrage that guiding slides, and ensures the stationarity of massage armchair under the state of weighing, reduces metrical error.Power source is electric pushrod, and the two ends of electric pushrod are movably hinged with mounting 1 and driving member 2 respectively, and in other embodiments, power source also can be air-leg or other pushing mechanisms.The bottom of push rod 5 is sensor holder 51, and sensor holder 51 is provided with mounting groove, and gravity sensor is arranged in mounting groove.Elastic matrix 52 comprises cantilever and hold-down arm, the cell wall of mounting groove is provided with plug-in type draw-in groove, hold-down arm is lamellar and inserts to be installed in draw-in groove, touch part 53 to be conflicted on cantilever and is protruded outside mounting groove, touch part 53 is provided with buckle, cantilever has support portion, touch part 53 is installed on support portion, and touch part 53 has the face of compressing, touch part 53 is pressed on support portion by compressing face, support portion is extended to side by the end of cantilever, and touch part 53 drives cantilever to produce elastic deformation by support portion.Resistance strain gage 54 is pasted on cantilever, and the elastic deformation amount of cantilever is converted to the change in resistance of resistance strain gage 54, thus the weight of human body.
Body weight information identification user identity is utilized and the massage program of customized personal by following technical measures in present embodiment.
Electric control gear comprises processing unit, memory element and operating unit, and processing unit controls gravity sensor and detects user's weight information and be stored in memory element the identity information being used as to identify this user.The height that user is inputted by operating unit by processing unit, sex or age information to be stored in memory element and using itself and above-mentioned weight information merger as the identity information identifying this user.Processing unit is selected this user to set or presets the massage program adapting to this user in the memory unit to control massage machine enforcement massage according to the identity information of user.So just can implement personalized massage program according to the identity of user.
Above embodiment is only preferred structure, and in other embodiments, guide also can be gathering sill, and driving member 2 slides and promotes push rod 5 and stretch in gathering sill, the sensor that weight sensor also can adopt solenoid, Hall element etc. equivalent with foil gauge.
Work process of the present invention is as follows: take massage armchair as user and start weighing procedures, electric control gear drives electric pushrod action to be driving member 2 forward rocking motion on mounting 1, driving member 2 promotes push rod 5 by connecting rod 4 and stretches out and the whole massage armchair of lifting, leg leaves ground, massage armchair supports on the ground by push rod 5, elastic matrix 52 is generation elastic deformation under the compressing of touch part 53, the resistance being fitted in the resistance strain gage 54 on elastic matrix 52 changes, electric control gear calculates according to the variable quantity of this resistance the weight judging human body and also stores in a register as the identity identification information of this user, operating unit can point out user to input its name, height, the identity information such as age and sex, above-mentioned information and weight information merger storage are used for identifying this user by processing unit, when this user again takes and massage armchair is massaged, with regard to this user of identifiable design after electric control gear drives weighing device again to weigh, the massage program that processing unit can set according to this user last time or the final massage program selected of its last time of massage are massaged, if this user needs to change other massage program, after only needing to carry out manual intervention, reset or select massage program.In addition, processing unit can be shown to user by display device or be transferred on telecreen by wireless communication apparatus and show after calculating the weight of human body, if this user body weight generation in a short time great change, electric control gear can remind this user to guard one's health.
