Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the wheelchair for assisting the elderly to move comprises a frame 10, a front wheel seat 15 and a rear wheel seat 14 installed at the left and right sides of the frame 10, a steering wheel 151 installed at the front wheel seat 15, a driving wheel 141 installed at the rear wheel seat 14, a hand-held ring 142 installed at the driving wheel 141 for the user to rotate the driving wheel 141, and a hand brake 16 for the wheelchair user to restrict the vehicle from moving. The frame is also provided with a seat plate 12 and a back plate 13, and the back plate 13 is provided with a handle 17 and a hand brake 171 for a maintainer or a family member to push the wheelchair.
In order to add a wheelchair for assisting the elderly to move, the bottom of the frame is provided with a mounting plate 11, the mounting plate 11 is provided with a lifting device, and the lifting device can adopt a compressed pneumatic support rod, which is called a pneumatic spring for short, or a pneumatic spring with a locking function. When the seat is in a normal level, the pneumatic spring is in a compressed state, and if the seat plate is opened, the seat plate can be automatically lifted by air pressure after force is removed, but the lifting position cannot be conveniently adjusted by the structure, and the better design is the lifting device 20 as further shown in fig. 1 and 3, wherein the lifting device 20 comprises a screw rod 23 driven by a motor, the screw rod 23 is provided with a slide block 21 which moves after rotating through the screw rod 23, the slide block 21 is provided with a hinged support 222, the hinged support is hinged with a push rod 22, and the other end of the push rod 22 is hinged to a hinged support 221 at the bottom of the seat plate 12; as shown in fig. 2, the lifting mechanisms 20 are provided in two side-by-side arrangement in order to improve the stability of the lifting of the seat pan.
In order to further ensure that the seat plate can stably rotate around the front side edge in the lifting process, namely, one end of the seat plate on the knee side is taken as a rotating shaft, as shown in fig. 3, rotating hinges 122 are arranged on the left side and the right side of the seat plate, in addition, one end of the push rod 22 hinged on the seat plate is arranged below the seat plate with the symmetric rotating shaft, and sliding heads 121 are arranged on the left side and the right side of the seat plate at the same transverse position, as shown in fig. 1, the sliding heads 121 move in the arc-shaped sliding grooves 24 on the two sides of the frame. The above structure shown in fig. 4 makes the sliding block 21 move from back to front when the screw is driven by the motor or the hand-operated rotating rod facing to the wheelchair, and the effect of pushing the seat plate 12 by the push rod is that the seat plate 12 tilts around the rotating hinge 122 as the rotating center, and the tilting angle is controlled by the rotation of the screw 22; since the screw rotates to drive the slider to move, the center of the rotation center has a certain displacement, and therefore, a certain horizontal displacement space needs to be provided for the rotary joint 122, i.e., the bracket 1221 in fig. 4. In addition, the screw 22 is driven by a motor or a hand-operated rotating rod, if the screw is stopped at the current position, a stopping deflector rod can be added, the stopping deflector rod is matched with a gear 230 at the end part of a rotating shaft of the screw, the mechanism is various in types and is a common mechanical structure, and therefore, the mechanism is not further shown in the drawing. Conversely, when the slide 21 is moved from front to back, the push rod pushes the seat plate to restore the seat plate to a horizontal state.
As further shown in fig. 4 and 7, the sliding head 121 has an internal threaded hole 1211 at the end thereof and a passive restraint ring 1210, the butterfly knob 25 includes an external threaded head 251 and an active restraint ring 252 that are engaged with the internal threaded hole 1211, and when the sliding head 121 moves in the arc chute 24 to reach a desired tilting angle, the butterfly knob 25 can be rotated such that the external threaded head 251 rotates into the internal threaded hole 1211, thereby allowing the distance between the active restraint ring 252 and the passive restraint ring 1210 to be reduced and restrained at both sides of the arc chute 24, thereby further stabilizing the seat board. The tilting effect of the seat plate can help the old to get up and stand or assist the old to walk upright in the rehabilitation training stage.
Further, since the armrests 19 are provided on both sides of the conventional wheelchair, the armrests of the wheelchair often abut against the table top, which causes an excessively long distance between the old sitting on the wheelchair and the table, and thus, the old is very inconvenient to eat or play. In order to solve this problem, the seat plate 12 is provided with an extension plate 18, which is coupled to the slide rail through a slide groove 181, and the extension length is controlled by using a stopper. As shown in fig. 5 and 6, the limiting device comprises a button 120 installed on the bottom surface of the seat plate 12, the button 120 drives an interlocking plate 121, the interlocking plate 121 has a limiting chuck 122, when the button is not pressed down, the limiting chuck 122 extends into a concave hole 123 on the seat plate, the concave holes 123 are arranged on the contact surface of the seat plate and the extending plate at equal intervals, a groove 182 for the movement of the interlocking plate 121 is formed in the bottom surface of the extending plate 18, a spring 183 is arranged in the groove 182, and the spring can be restrained in a round hole to avoid loosening. During the use, the hand stretches to seat board below, upwards presses button 120, and button 120's action stroke is greater than the height of recess 182, the linkage board 121 lifting of messenger to drive spacing dop 122 break away from shrinkage pool 123 and during the retraction groove, the adjustable flexible length of board is stretched in the pulling this moment, loosens the button, and linkage board 121 lets spacing dop 122 stretch into other shrinkage pools 123 under spring 183's self-recovery.
Another kind of design is drop-down formula structure, and there is the spacing buckle of spring seat board bottom, and the spacing buckle of drop-down then separates from the shrinkage pool, realizes stretching the board and slides on the seat board, if loosen the spacing buckle of drop-down, then stretch the board and can not slide on the seat board.
When the old people sit on the wheelchair and need to get close to the desk for eating, the extension plate can be pulled out, so that the old people can get close to the desk as much as possible, and the old people can conveniently eat food.
