The guiding rod 202 extends along the vertical direction of the lifting rod 102, and the lifting rod 102 moves up and down along the guiding rod 202.
It shall be understood that the lifting rods 102 may be arranged into two operating states relative to the base 201.
In a first operating state, the lifting rod 102 only moves up and down along the guiding rod 202. In this case, the seat plate 101 is movably connected to the lifting rod 102, and the seat plate 101 rotates around the lifting rod 102.
In a second operating state, the lifting rod 102 moves up and down along the guiding rod 202 and further rotate around an axis of the lifting rod 102 itself. In this case, the seat plate 101 is fixedly connected to the lifting rod 102, and the seat plate 101 rotates as the lifting rod 102 is rotating around the lifting rod 102 itself.
For the electronic lifting-lowering transfer machine disclosed in the present disclosure, the pushing rod 213, which is arranged with the electronic controlling assembly 210, drives the lifting rod 102 and the connecting rod 220 to be lifted or lowered to further drive the main body assembly 100 to 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 assembly 210 to reset the transfer machine without applying forces to the seat plate 101.
In the present disclosure, the lifting assembly 200 further includes the connecting rod 220 and the electronic controlling assembly 210 for driving the connecting rod 220 to move up and down. On one hand, the connecting rod 220 is fixedly connected to the lifting rod 102. On the other hand, the connecting rod 220 is connected to the pushing rod 213. When the main body assembly 100 moves upwardly, the electronic controlling assembly 210 drives the pushing rod 213 to move upwardly. The pushing rod 213 drives the connecting rod 220 and the lifting rod 102 to move upwardly, further driving the entire main body assembly 100 to move upwardly, allowing the seat plate 101 to reach a desired height, and vice versa.
In some embodiments, the connecting rod 220 is further arranged with a foot pedal 300 for the user to place feet. Regardless of the height of the main body assembly 100, a distance between the foot pedal 300 and the seat plate 101 is a fixed value. That is, the foot pedal 300 is lifted and lowered simultaneously as the main body assembly 100 is lifted and lowered, such that the user may be always comfortable when being lifted or lowered.
In addition to the above embodiments, the lifting rod 102 is arranged vertically on the base 201. The lifting rod 102 is arranged to sleeve the guiding rod 202 in the up-down direction. A circumference of the lifting rod 102 is connected to the connecting rod 220.
In the present embodiment, the main body assembly 100 moving upwardly and downwardly is defined as the main body assembly 100 being lifted and lowered in a height direction. The lifting rod 102 is arranged vertically and fixedly connected to the base 201. The guiding rod 202 is arranged in the height direction. An axial direction of the lifting rod 102 and an axial direction of the guiding rod 202 are the same. The lifting rod 102 is arranged to sleeve the guiding rod 202. The circumference of the lifting rod 102 is connected to the connecting rod 220. When the pushing rod 213 applies a force to allow the connecting rod 220 (lifting rod 102) and the guiding rod 202 to move relative to each other, the main body assembly 100 gradually moves to reach a desired lifting-lowering amplitude.
In addition to the above embodiment, the seat plate 101 includes 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 plate 101 comprises 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 rods 102. When the two seat plates 101 reach the desired height, the two seat plates 101 may 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 plates 101 are connected by the snap, and the alignment pin fixes the snap through the alignment hole, such that the two seat plates 101 are closed with each other.
In addition to the above embodiment, the electronic controlling assembly 210 further includes a driving assembly 211, a transmission assembly 212 and a control assembly. The driving assembly 211 is configured as a motor. The transmission assembly 212 is 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 box 203 is arranged at a front of the base 201, and the control assembly is arranged inside the control box 203.
In the present embodiment, the driving assembly 211 is one of a stepper motor and a servo motor. Lifting and lowering the pushing rod 213 may be achieved by the motor rotating forwardly and reversely. Further, the electronic controlling assembly 210 further 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 rod 213 can be self-locked. The remote control assembly may control the pushing rod 213 to be stopped at any height, improving responsiveness and stability of the transfer machine.
In the present embodiment, the upper surface of the control box 203 may be flat, serving as the foot pedal 300 for the user to place the feet when sitting still.
Further, the electronic controlling assembly 210 further 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 rod 102.
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 assembly 100 and the connecting rod 220 are lifting and lowering, two operating states exist.
First Operating State:
When the main body assembly 100 and the connecting rod 220 are 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 rod 213 may be protected. It shall be understood that when the main body assembly 100 and the connecting rod 220 reach the highest position or the lowest position, the circuit is automatically disconnected, and the pushing rod 213 stops moving, increasing safety of the transfer machine.
Second Operating State:
When the main body assembly 100 and the connecting rod 220 are 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.
