Specific embodiment
The utility model is described in further detail below by specific embodiment combination attached drawing.
This example provides a kind of wearable L-type gait detection device, by ingehious design, simplifies the complexity of structure, repeatedly
The precision of gait detection is still ensured that after use.
Its structure chart is as shown in Figure 1, L-type gait detection device includes force snesor 1, is worn on user's calf and foot
L-type support 2 and socket part 3, when L-type support 2 is worn on user's calf and foot, the transverse part 21 of L-type support 2, which is located at, to be used
The vertical portion 22 of the foot bottom at family, L-type support 2 is located at user's shank rear, and force snesor 1 is set to the vertical portion of L-type support 2
22, socket part 3 is sheathed on the vertical portion 22 of L-type support 2, until force snesor 1 is accommodated to socket part 3, in the step of user
In the state period, force snesor 1 detects the dynamic force generated between socket part 3 and L-type support 2, when what force snesor 1 will test moves
State power is sent to background processor, and background processor generates " power-time " relevant pressure waveform figure according to dynamic force, and to step
Waveform diagram in the state period is analyzed and is studied, to analyze gait situation locating for measurand.
Wherein, the variation of dynamic force and gait is closely bound up, and a gait cycle is divided into two stages, is respectively
" driving phase " and " recovery phase ", a complete gait cycle schematic diagram is as shown in Fig. 2, as shown in Figure 2, in gait cycle
Different moments, the tilt angle of user's calf is different, therefore, can use user's calf to the vertical portion of L-type support 2
22 force size and direction are different, identify " driving phase " and " recovery phase " in gait cycle, and this example uses two power
Sensor distinguishes user's calf to the force of L-type support 2；Further, the force snesor 1 of this example includes the first force snesor 11
With the second force snesor 12, the first force snesor 11 be set to vertical portion 22 towards user calf side, the second power pass
Sensor 12 is set to vertical portion 22 backwards to the side of the calf of user, when socket part 3 is sheathed on vertical portion 22 and until first
When force snesor 11 and the second force snesor 12 are accommodated to 3 inside of socket part, when the user walks, the first force snesor 11 and the
Two force snesors 12 detect user's calf power different to the application size of vertical portion 22 of L-type support 2 and direction.
Specifically, socket part 3 applies pressure to vertical portion 22 and pulls to power, e.g., when user is small in user's walking process
When leg is tilted along direction of travel, socket part 3 drives vertical portion 22, power is pulled to accordingly to generate, when inclining for user's calf
When tilted direction and direction of travel are reversed, socket part 3 presses to vertical portion, to generate corresponding pressure, due to pressure and pulls to
The direction of power is different, therefore, as shown in the pressue-graph in Fig. 2, pressure DYNAMIC DISTRIBUTION in pressure curve in positive axis,
And power DYNAMIC DISTRIBUTION is pulled on the negative semiaxis in pressure curve, moreover, as shown in Figure 2, on pressure curve corresponding to positive axis
Pressure maximum value at the time of for driving phase initial time, pull to power most corresponding to negative semiaxis on pressure curve
It is the initial time of recovery phase at the time of big value, therefore, background processor is according to the DYNAMIC DISTRIBUTION energy of pressure on pressure curve
Analyze gait situation when user's walking.
Further, due to the first force snesor 11 and the second force snesor 12 detect be socket part 3 and vertical portion 22 it
Between the dynamic force that generates improved to increase the contact area of the first force snesor 11 and the second force snesor 12 and socket part 3
The detection accuracy of force snesor 1, it is preferred that first force snesor 11 is vertically arranged to calf of the vertical portion 22 towards user
Side, the second force snesor 12 are vertically arranged to vertical portion 22 backwards to the side of the calf of user, that is, according to the structure of this example
Design, by the longitudinal contact area for increasing force snesor 1 and socket part 3.
Further, the transverse part 21 of the L-type support 2 of this example and vertical portion 22 are rectangular slab, and socket part 3 is in hollow rectangular
Tubulose, when socket part 3 is sheathed on vertical portion 22, socket part 3 is passed relative to the first side of the first force snesor 11 and the first power
Sensor 11 is in contact, and socket part 3 is in contact relative to the second side of the second force snesor 12 with the second force snesor 12, and first
Force snesor 11 is in the pressure that detection first side generates vertical portion 22 in gait cycle, and the second force snesor 12 is in gait
Detection second side pulls to power to what vertical portion 22 generated in period；In gait cycle, when the calf of user is relative to foot
When perpendicular to ground, since calf does not generate active force to socket part 3, the first force snesor 11 and the second power sensing
The detected value of device 12 is zero.
Further, for the user for keeping L-type gait detection device different suitable for height, 3 movable sleeve of socket part of this example
Set on vertical portion 22, according to the difference of the calf length of user, the socket height of appropriate adjustment socket part 3 and vertical portion 22.
Further, the socket part 3 of this example is equipped with the first connector 4 with the wearing connection of the calf of user, transverse part 21
Equipped with the second connector 5 for dressing connection with the foot of user, first connector 4 and the second connector 5 of this example are preferably tied up
Band can also realize the calf and foot of L-type gait detection device and user in other embodiments using other fixed forms
Portion's connection.
The socket part 3 of this example is vertically equipped with first connector 4, and in other embodiments, socket part 3 is vertically
On two even more first connectors 4 can be set, to reinforce the secured connection of the calf of socket part 3 and user, into
One step reinforces fastness when L-type gait detection device use state.
This example is by designing the simple structure of wearable L-type gait detection device and the design position of force snesor, not only
Facilitate the dynamic force in the gait cycle of detection user, so that background processor is analyzed and is studied, moreover, by ingehious design,
Increase the service life of wearable L-type gait detection device.
Use above specific case is illustrated the utility model, is merely used to help understand the utility model, and
Not to limit the utility model.Think of for those skilled in the art of the present invention, according to the utility model
Think, several simple deductions, deformation or replacement can also be made.
