While touching, the assembly space between drive crank 51 and connecting rod 53 is also added, can prevent from actively shaking in subsequent movement
Interference is generated between bar 51 and passive rocking bar 52.
In conjunction with Fig. 2 and Fig. 3, outer layer leg support assembly 2 includes outer layer leg support plate 21, parallel set on 21 back side of outer layer leg support plate
Two sliding rails 22 and the outer layer leg support fixing piece 23 for being connected to 21 back side of outer layer leg support plate.The face equipped with track slot of sliding rail 22
It is oppositely arranged, track slot is arranged along the glide direction of internal layer leg support assembly 3, and is formed between 21 back side of sliding rail 22 and outer layer leg support plate
There is fit-up gap, the fit-up gap is for installing internal layer leg support assembly 3；One end of the close connecting rod 53 of sliding rail 22 passes through axis pin
533 is hinged with connecting rod 53.
In conjunction with Fig. 2 and Fig. 3, internal layer leg support assembly 3 includes the fit-up gap for being set to outer layer leg support plate 21 and being formed with sliding rail 22
Interior internal layer leg support plate 31, the sliding block 32 in sliding rail 22 and be connected to 31 back side of internal layer leg support plate internal layer leg support it is solid
Determine part 9.The width of internal layer leg support plate 31 is less than the width of outer layer leg support plate 21, and sliding block 32 passes through STATEMENT OF FEDERALLY SPONSORED 7 and connecting rod driving group
Part 5 connects.
In conjunction with Fig. 4 and Fig. 5, STATEMENT OF FEDERALLY SPONSORED 7 includes 22 disposed in parallel two extension rods 71 of opposite sliding rail, is set to extension rod 71
Separate sliding block 32 end universal driving shaft 73 and the interlocking bar 72 that is connected between universal driving shaft 73 and fixing axle 55.Linkage
The both ends of axis 73 are rotatablely connected with the extension rod of both sides 71 respectively, end and the sliding block 32 of the separate fixing axle 55 of extension rod 71
Side far from sliding rail 22 is fixedly connected；One end of interlocking bar 72 is fixedly connected with universal driving shaft 73, and the other end is solid with fixing axle 55
Fixed connection so that fixing axle 55 and universal driving shaft 73 form an entirety.And it is fixedly connected between the extension rod 71 of both sides
Axis 74 is reinforced, the position that axis 74 is located at the close sliding block 32 of extension rod 71 is reinforced, reinforces the extension rod 71 that axis 74 strengthens both sides
Between structural strength.
Since fixing axle 55 is fixedly connected with fixing bracket 61, interlocking bar 72 is fixed with fixing axle 55 and universal driving shaft 73 to be connected
It connects, therefore interlocking bar 72 forms a fixed body by fixing axle 55 and fixing bracket 61, therefore extension rod 71 and sliding block 32
It can only be rotated relative to the body around universal driving shaft 73, holder 61 will not be relatively fixed and generate movement.
In conjunction with Fig. 4, when device is in retracted state, sliding block 32 is located at one end of the separate axis pin 533 of sliding rail 22, actively
Rocking bar 51 is in vertical state with sliding rail 22, since height of the second hinge joint b on connecting rod 53 exists higher than third hinge joint c
Height on connecting rod 53,53 lower end of connecting rod is simultaneously by the upward pulling force of drive crank 51 and passive rocking bar 52（f1、f2）（Ginseng
Examine Fig. 6）, therefore connecting rod 53 is in stationary state, even if the upper end of connecting rod 53 is influenced by the dead weight of sliding rail 22, will not send out
Raw rotation so that the leg support being capable of self-locking in retracted state.
Drive drive crank 51 around synchronizing bar 42 when driving motor 43 drives recliner 41 to rotate in conjunction with Fig. 1 and Fig. 4
It is rotated to the direction far from seat body 1, under the drive of articulated shaft 54, drive crank 51 generates the directions F1 in 53 lower end of connecting rod
Thrust（With reference to figure 6）, drive link 53 rotates around axis pin 533 to the direction far from seat body 1, at the same connecting rod 53 it is whole to
Upper movement, 52 lower end of passive rocking bar are rotated around fixing axle 55 to the direction far from drive crank 51 under the drive of connecting rod 53, even
Angle between bar 53 and passive rocking bar 52 increases.In conjunction with Fig. 5, the connecting rod 53 moved upwards can be at axis pin 533 to sliding rail 22
Generate the driving force in a direction F（With reference to figure 6）, sliding block 32 is relatively fixed the fixation of holder 61, and the drive force in the directions F is slided
It is sliding since passive rocking bar 52 has pulling force in the lower end of connecting rod 53 simultaneously while rail 22 is moved downward along sliding block 32
Rail 22 can also be rotated around axis pin 533 to the direction far from seat body 1, to movable slider 32 around universal driving shaft 73 to separate
The direction of drive crank 51 rotates；Therefore connecting rod 53, while drive entire leg support device to be lifted up, outer layer leg support plate 21 is along interior
Layer leg support plate 31 stretches out so that whole device is in unfolded state.
In conjunction with Fig. 7, the rib of the close fixing axle 55 of drive crank 51 is equipped with protrusion 512, and drive crank 51, which rotates, to be made
During device is opened, protrusion 512 with fixing axle 55 when abutting so that the movement stopping of device, drive crank 51 can not be after
Continuous rotation, sliding block 32 is located at one end equipped with axis pin 533 of sliding rail 22 at this time.Protrusion 512 can be by limiting drive crank 51
It moves to limit the stroke that leg support device moves upwards, anti-limited slip block 32 is detached from sliding rail 22 so that the structure of device is destroyed.
In conjunction with Fig. 8, when whole device is in unfolded state, third bending part 532 and the passive rocking bar of 53 lower end of connecting rod
4th bending part 521 of 52 lower ends abuts so that connecting rod 53 is mutually stuck with passive rocking bar 52, connecting rod 53 and passive rocking bar 52 it
Between angle can not continue growing so that entire mechanism is in self-locking state.Even if outer layer leg support plate 21 is by downward
The stuck state of pressure, the mechanism will not be destroyed, and the clamping between connecting rod 53 and passive rocking bar 52 only can be more close,
So that whole device is more firm.Fig. 1 and Fig. 5 are reviewed, when driving motor 43 drives recliner 41 to rotate backward again,
Drive crank 51 is driven to be rotated to close to the direction of seat body 1 around synchronizing bar 42, connecting rod 53 is around axis pin 533 to close to seat sheet
The direction of body 1 rotates, while connecting rod 53 moves downward, and connecting rod 53 and the clamping of passive rocking bar 52 release, connecting rod 53 with shaken
Angle between bar 52 reduces；Sliding rail 22 is rotated around axis pin 533 to close to the direction of seat body 1, at the same along sliding block 32 to
Close to the movement of the direction of seat body 1, to be rotated to close to the direction of drive crank 51 around universal driving shaft 73 with movable slider 32；Therefore
While connecting rod 53 drives entire leg support device to withdraw downwards, outer layer leg support plate 21 is retracted along internal layer leg support plate 31 so that entire
Device is in retracted state.In conjunction with Fig. 9, the upper end of passive rocking bar 52 is abutted with the second bending part 531 of connecting rod 53 at this time, connecting rod
Angle between 53 and passive rocking bar 52 can not continue to reduce, and the movement of device stops.
As a preferred embodiment, reviewing Fig. 3, outer layer leg support plate 21 is rectangular, the side of outer layer leg support plate 21
Side is vertically equipped with multiple summits edge, and edge is set as three and is connected with each other, and includes the separate internal layer leg support positioned at outer layer leg support plate 21
Positive edge 211 on the side of plate 31 and positioned at 21 both sides of outer layer leg support plate and the two lateral sides parallel with sliding rail 22
