Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.It should be noted that not rushing
In the case where prominent, the feature in following embodiment and embodiment be can be combined with each other.
The mechanical finger for pulse-taking instrument of the utility model is for being mounted on pulse-taking instrument, for simulating pressing for traditional Chinese physician
Pulsation is made, and the pulse information of detected person is acquired by the pressure sensor being arranged on mechanical finger.
As shown in Figs. 1-2, the mechanical finger for pulse-taking instrument in the utility model embodiment is mainly by fixed column 20, pendulum
Swing arm 10, pressure sensor module 30 and driving device composition, wherein fixed column 20 extends along the vertical direction, fixed column 20
Upper end is fixing end 22, and lower end is free end 24.The fixing end 22 of fixed column 20 and the finger actuation mechanism of pulse-taking instrument are (in figure not
Show) connection, 20 oscilaltion campaign of fixed column is driven by finger actuation mechanism, so that entire mechanical finger be driven to rise up and down
Drop movement.
Swing arm 10 be mainly used for install pressure sensor module 30, swing arm 10 include arm 12 and under arm 12
The head 14 of connection is held, the bottom surface on head 14 is sensor mounting surface.Head 14 and the free end 24 of fixed column 20 pass through shaft
40 are rotatably coupled, so that sensor mounting surface 40 can be swung within the scope of certain angle around the shaft.
Pressure sensor module 30 includes multiple pressure sensors, connecting wire and the data processing chip of matrix arrangement,
Multiple pressure sensors are mounted on the sensor mounting surface, and multiple pressure sensors have the pressure contacted with human skin
Sensing face, multiple pressure sensors are connect by connecting wire with data processing chip.Pressure sensor module 30 passes through fixation
Block 90 is fixed on arm 12.
Driving device is for driving the swing arm 10 to swing around the shaft 40.The driving device include power source and

As shown in figure 3, the gear drive includes intermeshing driven gear 50 and driving gear 60, it is described from
Moving gear 50 is mounted on the swing arm 10, and concentric with the shaft 40.In order to reduce volume, mitigate weight, it is described from
Moving gear 50 is sector gear.The driving gear 60 is connect with the output end of the power source.It is described dynamic in the present embodiment
Power source is steering engine 70, and the steering engine 70 is mounted on the fixed column 20 back to the side of the arm 12 by mounting blocks 80.
The above-mentioned mechanical finger for pulse-taking instrument, due to sensor mounting surface can around the shaft 40 axis oscillating so that
The pressure-sensing face of pressure sensor 40 can be swung within the scope of certain angle around the shaft, be connect when pressure-sensing face with human skin
It can get pressure value signal when touching and pressure-sensing controlled by driving device further according to the distribution of matrix pressure value signal
Face is adjusted to reasonable angle, to obtain more accurate pulse signal.
After being contacted due to the pressure-sensing face of pressure sensor with human skin, when swing arm 10 rotates, pressure
Sensing face rotates with it the frictional force that can bring pressure-sensing face and skin, and shaft 40 is smaller at a distance from pressure-sensing face, pressure
The amplitude of oscillation of power sensing face is smaller, and the friction between pressure-sensing face and human skin is smaller, and comfort is higher；Moreover, pressure passes
After the pressure-sensing face of sensor is contacted with human skin, swing arm 10 can generate lateral reaction force, shaft to fixed column 20
40 is smaller at a distance from pressure-sensing face, and reaction force is smaller.In order to reduce shaft 40 at a distance from pressure-sensing face, described
Head 14 with the sensor mounting surface back to surface on be provided with mounting groove 142, the peace is inserted into the free end 24
In tankage 142, the both ends of the shaft 40 are supported on respectively in the two side walls of the mounting groove 142.Make shaft 40 in this way
Axis closer to pressure-sensing face.It is further preferred that between the axis of the shaft 40 and the sensor mounting surface
Spacing is less than 2mm.
Preferably, the surface of the pressure sensor is covered with protective case (not shown).Protective case can promote to press
Power sensing face with take being bonded for arteries and veins tested surface, obtain more accurate pulse signal, and play it is anti-scratch, anti-corrosion, antistatic etc. are protected
The effect for protecting sensor, improves the service life of sensor.
In use, finger actuation mechanism drives fixed column 20 to move downward, so that swing arm 10 be driven to move downward, swing
During arm 10 moves downward, when the head of swing arm 10 14 is contacted with human skin, control system acquires pressure sensor
The pressure value that module 30 acquires calculates the positional relationship between feeling of stress side and human skin according to pressure value, thus according to
Calculated result controls driving device driving swing arm 10 and rotates, and pressure-sensing face is made to be adjusted to reasonable angle, more smart to obtain
True pulse signal.
In conclusion the mechanical finger for pulse-taking instrument of the utility model embodiment has the advantages that
