Overturning play better limit effect, avoid cushion 12 crooked in active procedure, more secure and reliable.
As shown in figure 5, the two sides of cushion 12 are equipped with side frame 5, side frame 5 is equipped with swivelling chute 51, and swivelling chute 51 is located at cushion
Front end position, 12 two sides of cushion are equipped with shaft 121, and shaft 121 is inserted into swivelling chute 51, guarantee that cushion 12 is only capable of generating in rear end
Overturning.
Side frame 5 is mutually fixed with pedestal, and side frame 5 is located at the two sides of pedestal, and knee-pad cover 6 is equipped between pedal 13 and side frame 5；Shield
Kneeboot 6 is the battened construction for abutting user's knee, and knee-pad cover 6 is " U "-shaped, is equipped between 6 both ends of knee-pad cover and side frame 5
Detachable structure, knee-pad cover 6 are located at 12 front of cushion, and 6 lower section of knee-pad cover is hanging and does not contact with pedal.Can protect first makes
The knee site of user, secondly can be when user be held up by stand-type electric wheelchair, through the knee actuator current amplifier for abutting user
Position, is supported the weight of entire body, user is avoided to slide.
Pedal 13 is equipped with foot's fixed block 130, and the effect of foot's fixed block 130 is that sole position is fixed, mesh
Preceding the present embodiment uses the form of groove, and the foot of user or shoes is fixed in a groove, is carried out user's sole with this
It is fixed.By fixed feet bottom, so that user's knee rests on knee-pad cover 6, reach to user's lower limb (shank and foot)
Fixation, it is more steady when so that the user is stood.
As shown in Figure 6 and Figure 7, detachable structure includes panel 54, caulking groove 60, stud 61 and nut 62, is set on panel 54
There is the through slot 53 passed through for stud 61, stud 61 is fixed on caulking groove 60, and nut 62 compresses panel 54 in 60 surface of caulking groove.Spiral shell
Column 61 includes external thread section 611 and connecting column 610, and 610 outer diameter of connecting column is less than 53 gap of through slot, and 611 outer diameter of external thread section is big
In 53 gap of through slot, the perforation 52 passed through for the external thread section 611 of stud 61 is additionally provided on panel 54,52 apertures of perforation are greater than
611 outer diameter of external thread section, perforation 52 are connected to through slot 53.
After external thread section 611 is pierced by perforation 52, external thread section 611 stays in the outside of through slot 53, the connecting column 610 of stud 61
In through slot 53, by the clamping structure, stud 61 is stuck on through slot 53, realize it is preliminary fixed, secondly by tightening spiral shell
Panel 54 is pressed in caulking groove 60 by mother 62, realizes that the side of knee-pad cover 6 is fixed.
As shown in figure 8, being equipped with the cushion 63 of corresponding knee on the inside of knee-pad cover 6, cushion 63 is located at detachable structure, passes through
Cushion 63 avoids knee site from directly contacting knee-pad cover 6, protects knee；Secondly the position knee-pad cover 6 of cushion 63 is directly by knee
The ejection strength of lid, therefore detachable structure is set up directly on the position, detachable structure is nearest apart from stress point, and avoiding can
Detaching structure stress deformation.63 middle part of cushion is arranged to lower recess, is bonded knee shape, knee is effectively protected.
As shown in figure 8, the both ends of knee-pad cover 6 are equipped with abutting part 64, abutting part 64 is located at the lower section of detachable structure；Due to
6 weight of knee-pad cover is concentrated in the front, therefore can be to be detachably connected the trend a little rotated, therefore passes through increase abutting part
64, abutting part 64 is mutually rested against with pedestal, for propping up knee-pad cover 6, it is avoided to fall off.
As shown in figure 9, being additionally provided with regulating mechanism between foot's fixed block 130 and pedal 13, regulating mechanism includes sliding slot
132, adjusting block 131, locking pressure plate 133 and clamping screw 134, adjusting block 131 are located at 130 bottom of foot's fixed block, sliding slot 132
Positioned at 13 surface of pedal, clamping screw 134 is tightened so that hypotelorism between locking pressure plate 133 and adjusting block 131, consolidates foot
Determine block 130 and locking pressure plate 133 clamps 13 two sides of pedal, realizes foot's fixed block 130 in the fixation on 13 surface of pedal.
The adjusting that can be controlled on sliding slot 132 to foot's fixed block 130 is unclamped, (no with practical different users
Same figure, different foots' spacing) use habit.
The above makes preferred embodiments of the present invention, does not depart from for those of ordinary skill in the art
Under the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model
Range.
