As shown inFIGS.1to3, the present disclosure provides an electronic lifting-lowering transfer machine, applied in the nursing field, facilitating people who have reduced mobility to move between wheelchairs and sofas, beds, toilets, seats, and so on.

The electronic lifting-lowering transfer machine may include following components.

A main body assembly100and a lifting assembly200are provided. The main body assembly100may include two lifting rods102, which may move upwardly and downwardly, and two seat plates101corresponding to the two lifting rods102. Each of the two seat plates101may rotate around the corresponding lifting rod102, such that the two seat plates101may be enclosed with or separated from each other. The lifting assembly200may include a base201, a connecting rod220fixedly connected to the lifting rods102and an electronic controlling assembly210.

The base201may include a guiding rod202extending in an up-down direction. The lifting rods102may move upwardly and downwardly along the guiding rod202. The electronic controlling assembly210may include a pushing rod213, which is fixedly connected to the connecting rod220for driving the lifting rods102to move upwardly and downwardly, further driving the main body assembly100to move upwardly and downwardly. The connecting rod220may have a first connecting portion221and a second connecting portion222. The first connecting portion221may be connected to the lifting rods102. The second connecting portion222may be connected to the pushing rod213. A foot section223may be formed between the first connecting portion221and the second connecting portion222. The foot section223may be configured for the user to place feet. In the present embodiment, the connecting rod220may form the foot section223. A distance between the foot section223and the seat plate101may be fixed. The foot section223may be lifted or lowered as the main body assembly100lifts or lowers. According to the present embodiment, no additional components are arranged and structural strength is ensured, and at the same time, when the seat plate101is positioned high, the user's feet may not overhang to occupy spaces for legs, and without overhanging, the feet may not swing to cause any danger to the user.

In detail, the first connecting portion221and the second connecting portion222are connected to each other through the foot section223. The first connecting portion221may be connected to the lifting rods102, and the second connecting portion222may be connected to the pushing rod213.

To be noted that, the foot section223may be a portion for resting feet. A height difference h may be between the first connecting portion221and the second connecting portion222. When h=0, the connecting rod220may be arranged horizontally; and when h≠0, the connecting rod220may be arranged unevenly, having a concave part and a convex part.

In some embodiments of the present disclosure, the h≠0, and the connecting rod220has the concave part and the convex part. A middle part of the connecting rod220may be configured to connect the pushing rod213, and may be the second connecting portion222. The middle part of the connecting rod220(the second connecting portion222) may be the convex part. Two sides of the second connecting portion222are recessed downwards to form the foot section223. An outer side of the foot section223may be the first connecting portion221, and the pushing rod213may be arranged within the convex part formed by the second connecting portion222. The first connecting portion221may be configured as a columnar structure, extending upwardly. Alternatively, the first connecting portion221may be configured as a connecting part at an end of the foot section223for being fixedly connected to the lifting rod102. In the embodiment shown inFIG.2of the present disclosure, the first connecting portion221is configured as the columnar structure, extending upwardly.

In the present embodiment, a reinforcement structure224may be disposed between the foot section223and the first connecting portion221and/or between the foot section223and the second connecting portion222.

In detail, the electronic lifting-lowering transfer machine may further include the reinforcement structure224. The reinforcement structure224may be disposed between the first connecting portion221and the foot section223, or between the second connecting portion222and a foot pedal300. Alternatively, the reinforcement structure224may be disposed between the first connecting portion221and the foot section223, and between the second connecting portion222and the foot section223.

In some embodiments, the reinforcing structure224may be a curved bending portion. The curved bending portion may reduce local stress deformation of the bending portion, compared to a structure having a right-angle bending portion.

It shall be understood that, the connecting rod220may be arranged to achieve tow effects. On the one hand, the connecting rod220may be configured to connect the pushing rod213and the lifting rod102. On the other hand, the foot section223may be formed between the first connecting portion221and the second connecting portion222for the user to rest feet. In this way, the connecting rod220may be any one or combination of a tube, a plate, and a solid rod. For example, each of the first connecting portion221and the second connecting portion222may be the tube, and the foot section223may be the plate.

When the foot section223is made of a columnar component, such as a pipe or a bar, the foot section223may be arranged with a rectangular foot pedal300to increase an area for placing feet, such that the feet the user may be placed more stably.

In the present disclosure, the main body assembly100includes two lifting rods102and two seat plates101. Each of the two seat plates may rotate around a corresponding one of the two lifting rods102, such that the two seat plates101may close or separate from each other to form a combination of seat plates101that is ergonomically friendly. The seat plates101may be configured for carrying weights. The user may sit on the seat plates101for a long time comfortably.

The guiding rod202extends along the vertical direction of the lifting rod102, and the lifting rod102moves up and down along the guiding rod202.

It shall be understood that the lifting rods102may be arranged into two operating states relative to the base201.

In a first operating state, the lifting rod102only moves up and down along the guiding rod202. In this case, the seat plate101is movably connected to the lifting rod102, and the seat plate101rotates around the lifting rod102.

In a second operating state, the lifting rod102moves up and down along the guiding rod202and further rotate around an axis of the lifting rod102itself. In this case, the seat plate101is fixedly connected to the lifting rod102, and the seat plate101rotates as the lifting rod102is rotating around the lifting rod102itself.

For the electronic lifting-lowering transfer machine disclosed in the present disclosure, the pushing rod213, which is arranged with the electronic controlling assembly210, drives the lifting rod102and the connecting rod220to be lifted or lowered to further drive the main body assembly100to move up and down to reach a desired height. The electronic lifting-lowering transfer machine of the present disclosure may solve the problem of overall inconvenience of nursing care, which is caused by absent of a uniform standard height for sofas, beds, toilets, seats, and so on, leading to difficulties in adapting to corresponding heights. The sling type hydraulic transfer machine on the market may be heavy and may not be easily carried by nursing staff, and the user may not sit on the hydraulic transfer machine on the market for a long time. Compared to the sling type hydraulic transfer machine on the market, the transfer machine of the present disclosure may have a simple structure and may be easily carried. While using the transfer machine of the present disclosure, the user may adjust the height of the transfer machine and move the transfer machine without getting up or moving. When the transfer machine of the present disclosure is not in use, the nursing staff may operate the electronic controlling assembly210to reset the transfer machine without applying forces to the seat plate101.

In the present disclosure, the lifting assembly200further includes the connecting rod220and the electronic controlling assembly210for driving the connecting rod220to move up and down. On one hand, the connecting rod220is fixedly connected to the lifting rod102. On the other hand, the connecting rod220is connected to the pushing rod213. When the main body assembly100moves upwardly, the electronic controlling assembly210drives the pushing rod213to move upwardly. The pushing rod213drives the connecting rod220and the lifting rod102to move upwardly, further driving the entire main body assembly100to move upwardly, allowing the seat plate101to reach a desired height, and vice versa.

In some embodiments, the connecting rod220is further arranged with a foot pedal300for the user to place feet. Regardless of the height of the main body assembly100, a distance between the foot pedal300and the seat plate101is a fixed value. That is, the foot pedal300is lifted and lowered simultaneously as the main body assembly100is lifted and lowered, such that the user may be always comfortable when being lifted or lowered.

In addition to the above embodiments, the lifting rod102is arranged vertically on the base201. The lifting rod102is arranged to sleeve the guiding rod202in the up-down direction. A circumference of the lifting rod102is connected to the connecting rod220.

In the present embodiment, the main body assembly100moving upwardly and downwardly is defined as the main body assembly100being lifted and lowered in a height direction. The lifting rod102is arranged vertically and fixedly connected to the base201. The guiding rod202is arranged in the height direction. An axial direction of the lifting rod102and an axial direction of the guiding rod202are the same. The lifting rod102is arranged to sleeve the guiding rod202. The circumference of the lifting rod102is connected to the connecting rod220. When the pushing rod213applies a force to allow the connecting rod220(lifting rod102) and the guiding rod202to move relative to each other, the main body assembly100gradually moves to reach a desired lifting-lowering amplitude.

In addition to the above embodiment, the seat plate101includes a left seat plate and a right seat plate. A closing position between the left seat plate and the right seat plate defines an alignment hole.

The electronic lifting-lowering transfer machine further includes a snap and an alignment pin. The alignment pin is connected to the snap through the alignment hole to close the left seat plate and the right seat plate.

In detail, the seat plate101comprises the left seat plate and the right seat plate. Each of the left seat plate and the right seat plate rotates around a corresponding one of the two lifting rods102. When the two seat plates101reach the desired height, the two seat plates101may be aligned, and then the user applies a force to the left seat plate and the right seat plate to close the two seat plates. In this way, the two seat plates101are connected by the snap, and the alignment pin fixes the snap through the alignment hole, such that the two seat plates101are closed with each other.

In addition to the above embodiment, the electronic controlling assembly210further includes a driving assembly211, a transmission assembly212and a control assembly. The driving assembly211is configured as a motor. The transmission assembly212is configured as a gear transmission mechanism. The control assembly includes a control circuit for controlling the motor to be initiated or stopped, and a power supply. A control box203is arranged at a front of the base201, and the control assembly is arranged inside the control box203.

In the present embodiment, the driving assembly211is one of a stepper motor and a servo motor. Lifting and lowering the pushing rod213may be achieved by the motor rotating forwardly and reversely. Further, the electronic controlling assembly210further includes a remote control assembly, a sensor adapted to the remote control assembly. The sensor is configured to receive an electrical signal from the remote control assembly to control the motor to be initiated or stopped.

To be noted that, the pushing rod213can be self-locked. The remote control assembly may control the pushing rod213to be stopped at any height, improving responsiveness and stability of the transfer machine.

In the present embodiment, the upper surface of the control box203may be flat, serving as the foot pedal300for the user to place the feet when sitting still.

Further, the electronic controlling assembly210further includes a limitation assembly. The limitation assembly includes a first limitation switch for limiting a highest position and a second limitation switch for limiting a lowest position.

Both the first limitation switch and the second limitation switch are arranged in the lifting rod102.

In the present embodiment, each of the first limitation switch and the second limitation switch is configured as a travel switch.

To noted that while the main body assembly100and the connecting rod220are lifting and lowering, two operating states exist.

First Operating State:

When the main body assembly100and the connecting rod220are lifted and lowered to reach an extreme position (the highest position or the lowest position), the circuit may be automatically controlled to be disconnected without being controlled by the remote control assembly, such that the pushing rod213may be protected. It shall be understood that when the main body assembly100and the connecting rod220reach the highest position or the lowest position, the circuit is automatically disconnected, and the pushing rod213stops moving, increasing safety of the transfer machine.

Second Operating State:

When the main body assembly100and the connecting rod220are lifting and lowering between the highest position and the lowest point, the remote control assembly may control a lifting/lowering amplitude.

The above description shows only preferred embodiments of the present disclosure and does not limit the scope of the present disclosure. Any equivalent structural changes performed under the inventive concept of the present disclosure and based on the specification and the accompanying drawings, applied directly or indirectly in other related technical fields, shall be included in the scope of the present disclosure.
