Description
Technical field
This utility model relates to the mechanism of standing, lie low of the wheelchair of the disabled people of a kind of legs and feet or old people's use, belongs to technical field of medical instruments.
Background technology
Along with the development of global economy with society, aged tendency of population is more and more serious, and aging population are more and more.Add the disabled people of the existing millions of legs and feet of China.They need the practical wheelchair of function to increase self care ability; And all there are defective in existing common wheelchair, electric wheelchair in varying degrees, and for example the function singleness of common wheelchair is generally only ridden instead of walk; Can lie; Functions such as toilet seat, all functions are manually, far can not satisfy the demand of user; And electric wheelchair generally can only be as single walking-replacing tool, and what have also only has a single function of standing or lie low, and under the situation of maloperation, can damage human body.Therefore, press for a kind of multifunctional wheelchair that can lie low, can stand again.
The utility model content
The purpose of this utility model is the deficiency to above-mentioned prior art, and a kind of mechanism of standing, lie low of wheelchair is provided.Adopt the wheelchair of this mechanism, can be according to the needs of user, the form that easily wheelchair is transformed into seat, lies, stands.
The purpose of this utility model realizes through following technical scheme: a kind of mechanism of standing, lie low of wheelchair; Comprise back rest, mounting, frame, lower limb frame, the rear end of back rest and mounting is hinged, and the top of the front end of mounting and lower limb frame is articulated on the frame jointly; It is characterized in that; Be provided with the electric pushrod of standing, lie low electric pushrod and connecting rod, the seat end of the said electric pushrod of standing is hinged with frame, rod end and mounting are hinged; The seat end of the described electric pushrod that lies low is hinged with frame, and the bottom of rod end and lower limb frame is hinged, and the two ends of said connecting rod are hinged with back rest and lower limb frame respectively.
The front end of said mounting is provided with the circular arc kidney slot, and the top of said lower limb frame is provided with and the corresponding pin hole in circular arc kidney slot position, and the circular arc kidney slot of the front end of mounting and the vertical pin hole of lower limb frame are through the pin socket connection.
The angle of described circular arc kidney slot equates with the angle of mounting from lying status to the state of standing.
The center of circle of said circular arc kidney slot is the front end of mounting and the common pin joint (abbreviate O point) of top on frame of lower limb frame.
When wheelchair is in the sitting posture state; The use function of standing, through the manipulation electric pushrod of standing, the electric pushrod of standing outwards stretches gradually; Mounting can rotate around the pin joint O point of front end gradually; Back rest under the effect of connecting rod around with the rotation of the pin joint of mounting, make mounting, back rest and lower limb frame jointly in a face, entire mechanism is in standing state.
When wheelchair is in the sitting posture state; When use lies low function; Through the manipulation electric pushrod that lies low, the electric pushrod that lies low outwards stretches gradually, and the lower limb frame can rotate to horizontal level gradually around vertical pin joint O point; Back rest rotates to horizontal level around the pin joint with mounting under the effect of connecting rod, entire mechanism is in lying status.Can realize lifting the leg-training ability under the lying status.
The angle of the circular arc kidney slot of mounting equates with the anglec of rotation of mounting; Being used for hinged pin drops in the circular arc kidney slot all the time; Back rest, mounting and lower limb frame can stop the optional position in predetermined angular range, even maloperation can not damage people's health yet.
This utility model is simple and reasonable, and reliability is high, and safe ready has increased the function that auxiliary user is stood and lain low on the basis of the function that common wheelchair has, and flexible operation has popular widely.

The specific embodiment
A kind of mechanism of standing, lie low of wheelchair comprises back rest 1, mounting 2, connecting rod 3, the electric pushrod 4 of standing, the electric pushrod 5 that lies low, frame 6 and lower limb frame 7.Back rest 1 is hinged with the rear end of mounting 2, the top of the front end of mounting 2, lower limb frame 7 and frame 6 common hinged and a bit (O point).It is the circular arc kidney slot in the center of circle that the front end of mounting 2 is provided with the O point; The angle of circular arc kidney slot equates with the anglec of rotation of mounting; The top of lower limb frame 7 is provided with the pin hole corresponding with the circular arc kidney slot; Circular arc kidney slot and pin hole are through the pin socket connection, and this pin drops in the circular arc kidney slot all the time.The two ends of connecting rod 3 are hinged with back rest and lower limb frame respectively.The seat end of electric pushrod 4 of standing is hinged with frame 6, and rod end and mounting 2 are hinged.The seat end of electric pushrod 5 of lying low is hinged with frame 6, and the bottom of rod end and lower limb frame 7 is hinged.All hinged pins that all uses are hinged.
As shown in Figure 1, for this utility model at the sitting posture state.When function is stood in use; Through the manipulation electric pushrod 4 of standing, the electric pushrod 4 of standing outwards stretches gradually, and mounting 2 can rotate around the pin joint O point of front end gradually; Back rest 1 rotates around the pin joint with mounting 2 under the effect of connecting rod 3; Make mounting, back rest and lower limb frame jointly in a face, the electric pushrod 5 that lies low this moment is failure to actuate, and entire mechanism is in standing state.When mounting 2 rests on the optional position in the anglec of rotation; The user maloperation electric pushrod 5 that lies low; This moment, the circular arc kidney slot of mounting 2 front ends guaranteed to be installed in lower limb frame 7 vertical pins all the time within it, thereby avoided causing because of lower limb frame 7 anglecs of rotation are excessive personal injury.
When wheelchair is in the sitting posture state; When use lay low function, through the manipulation electric pushrod 5 that lies low, the electric pushrod 5 that lies low outwards stretched gradually; Lower limb frame 7 can rotate to horizontal level gradually around vertical pin joint O point; Back rest 1 rotates to horizontal level around the pin joint with mounting 2 gradually under the effect of connecting rod 3, the electric pushrod 4 of standing this moment is failure to actuate, and entire mechanism is in lying status.Can realize lifting the leg-training ability simultaneously when lying low.Back rest, mounting and lower limb frame can stop the optional position in predetermined angular range, even maloperation can not damage people's health yet.
More than show and described ultimate principle of this utility model and the advantage of principal character and this utility model; The technical staff of the industry should understand; This utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the description that this utility model just is described, under the prerequisite that does not break away from this utility model spirit and scope, this utility model also has various changes and modifications; These variations and improvement all fall in this utility model scope that requires protection, and this utility model requires protection domain to be defined by appending claims and equivalent thereof.
