[0033] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0034] See Figures 1 to 6 The transfer machine provided in this embodiment includes a support mechanism 100, a lifting assembly 200, and a hand-held lifting mechanism 300.
[0035] The support mechanism 100 has multiple movable wheels 110, and one end of the support mechanism 100 extends upward and is provided with a connecting part. One end of the lifting assembly 200 is hinged to the connecting part for vertical rotation, and the other end is a lifting end for connecting tools for supporting the patient. The electric lifting mechanism 300 is disposed on and hinged to the support mechanism 100. The electric lifting mechanism 300 has a movable end, which is hinged to the lifting assembly 200. The electric lifting mechanism 300 includes a drive assembly 310 and a manual adjustment assembly 320. The drive assembly 310 is drivenly connected to the movable end, and the manual adjustment assembly 320 is drivenly connected to the drive assembly 310.
[0036] Among them, the hinge shafts of the lifting assembly 200 and the connecting part, the hinge shafts of the electric lifting mechanism 300 and the support mechanism 100, and the hinge shafts of the electric lifting mechanism 300 and the lifting assembly 200 are parallel to each other, and the drive assembly 310 drives the moving end to push the lifting assembly 200 to adjust the height of the lifting end.
[0037] Specifically, in the transfer machine provided in this embodiment, the support mechanism 100 supports the lifting and lowering assembly 200 and the electric lifting mechanism 300. The bottom of the support mechanism 100 is provided with multiple moving wheels 110 to facilitate the movement of the transfer machine.
[0038] Furthermore, in this embodiment, the lifting assembly 200 is mounted on and hinged to the connecting portion at the top of the support mechanism 100, allowing the lifting assembly 200 to rotate along the connecting portion. The electric lifting mechanism 300 is mounted on and hinged to the support mechanism 100, allowing the electric lifting mechanism 300 to rotate along the hinge point. The moving end of the electric lifting mechanism 300 is hinged to the lifting assembly 200. The lifting assembly 200, the electric lifting mechanism 300, and the support mechanism 100 form a stable triangular structure to ensure structural strength during use.
[0039] In use, the moving end can be driven upward by the drive component 310, thereby pushing the lifting component 200. The lifting component 200 rotates at the hinge point between its lower edge and the support mechanism 100, and the lifting end achieves lifting and lowering action.
[0040] When the height of the lifting end is manually adjusted, the drive component 310 connected to it can be driven by the manual adjustment component 320, thereby causing the lifting component 200 to move. This allows the moving end to achieve lifting and lowering movements under the action of the manual adjustment component 320, without the need for manual adjustment of the moving end. The point of force application will not change due to the lifting and lowering movements, making the operation convenient and more labor-saving.
[0041] In this embodiment, the flashlight lifting mechanism 300 further includes a first rotating member 330 and a moving member 340. The first rotating member 330 is connected to the drive assembly 310 for transmission. One end of the moving member 340 is the moving end, and the other end is threadedly connected to the first rotating member 330.
[0042] Specifically, in this embodiment, the lifting assembly 200 is pushed by a screw structure formed by the first rotating member 330 and the moving member 340. One end of the moving member 340 is a movable end hinged to the lifting assembly 200. Due to the constraint of the hinge structure, the moving end cannot rotate circumferentially. When the first rotating member 330 rotates with the drive assembly 310, the moving member 340 moves along the axial direction of the first rotating member 330 under the rotation of the first rotating member 330, thereby adjusting the height of the moving end, and thus driving the lifting assembly 200 to move together, thereby adjusting the height of the connecting part.
[0043] In this embodiment, the drive assembly 310 includes a drive motor 311 and a first transmission member 312. The drive motor 311 is connected to the first rotating member 330 via the first transmission member 312.
[0044] In this embodiment, the drive motor 311 is connected to the first rotating component 330 through the first transmission component 312 to ensure the smooth transmission of kinetic energy.
[0045] Specifically, in this embodiment, the first transmission component 312 is a worm gear structure. Under this structure, the drive motor 311 can be set on one side of the first transmission component 312. The shaft of the drive motor 311 is horizontally set and the rotation drive of the first rotating component 330 is realized through the transmission structure of the worm gear.
[0046] In addition, the worm gear has a self-locking characteristic, which can be used to lock the height after the height adjustment is completed.
[0047] In this embodiment, the manual adjustment component 320 includes an adapter 321 and a commutator 322.
[0048] One end of the adapter 321 is connected to the first transmission member 312. The commutator 322 has a rotation input end located on the side of the commutator 322. One end of the commutator 322 has an extended rotating part that is connected to the input end and connected to the other end of the adapter 321.
[0049] In this embodiment, the output end of the commutator 322 is located on the side of the commutator 322. The rotating part is driven to rotate by rotating the input end of the commutator 322. The adapter 321 is used for the transmission connection between the rotating part and the first transmission member 312, so that the rotating part can drive the first transmission member 312 to rotate together, thereby driving the first rotating member 330 to rotate, and then driving the moving member 340 to push the lifting assembly 200 to move.
[0050] It should be noted that the adapter 321 and commutator 322 in this embodiment are conventional parts in the prior art that can be directly purchased and are commonly used parts in the field, so they will not be described in detail here.
[0051] Furthermore, in this embodiment, a crank can be inserted into the input terminal, and the input terminal can be rotated by turning the crank, thereby driving the rotating part to rotate.
[0052] In this embodiment, the two ends of the adapter 321 are respectively sleeved on the first transmission member 312 and the rotating part. The adapter 321 is detachably connected to the first transmission member 312 and the commutator 322 by means of pins.
[0053] Specifically, in this embodiment, the end of the first rotating member 330 near the adapter 321 has a convex transmission end. The cross-sections of the transmission end, the rotating part, and the adapter 321 are all hexagonal. The transmission end and the rotating part are respectively adapted to the two ends of the adapter 321. The two ends of the adapter 321 are respectively sleeved on the outside of the transmission end and the rotating part. Both ends of the adapter 321 have through holes. Correspondingly, the transmission end and the rotating part have positioning holes opposite to the positions of the through holes. In this embodiment, the pin is inserted into the positioning hole after passing through the through hole, so that the first rotating member 330, the adapter 321, and the rotating part can rotate synchronously.
[0054] It should be noted that in this embodiment, the manual adjustment component 320 is provided with a protective cover, which covers the transmission end, commutator 322 and adapter 321 to protect the three components.
[0055] In this embodiment, the support mechanism 100 includes a leg assembly 120 and a support assembly 130. The leg assembly 120 has an access channel located below the lifting end and open on one side. The leg assembly 120 includes an adjustment section 121 for adjusting the width of the access channel. Multiple casters 110 are spaced apart at the bottom of the leg assembly 120. One end of the support assembly 130 is connected to the leg assembly 120, and the other end is a connecting section.
[0056] In this embodiment, when the access channel is adjusted to its maximum width, the width of the access channel is greater than that of a conventional wheelchair. This means that a conventional wheelchair can enter the access channel from its open end, allowing patients with mobility issues to move to the area below the lifting end.
[0057] In this embodiment, the outrigger assembly 120 further includes outriggers and a second rotating member. There are two outriggers arranged in a trapezoidal interval. The second transmission member 122 is connected to the adjustment part 121 and the two outriggers respectively, and the adjustment part 121 adjusts the included angle between the two outriggers through the second transmission member 122.
[0058] Specifically, in this embodiment, an access passage is formed between the two outriggers. The distance between the ends of the two outriggers furthest from the access passage is small, while the distance between the ends of the two outriggers with the access passage is large. The adjustment unit 121 can drive the ends of the two outriggers with the smaller distance to move closer together through the second transmission member 122, thereby moving the two outriggers to increase the included angle between the two outriggers, and thus increase the width of the access passage to facilitate wheelchair entry.
[0059] Correspondingly, after use, the adjustment unit 121 and the second transmission member 122 can be used to drive the ends of the two legs with a smaller distance to move away from each other, thereby reducing the included angle between the two legs and thus reducing the space occupied by the shifting machine.
[0060] In this embodiment, the adjustment part 121 is a pedal. The second transmission member 122 includes a second rotating member and a rotating connecting rod 123. The second rotating member is throttledly connected to the pedal. One end of the rotating connecting rod 123 is hinged to the second rotating member, and the other end is hinged to the support leg. There are two rotating connecting rods 123, each corresponding to one of the two support legs. The pedal has a first end and a second end. Pressing down the first end or the second end causes the second rotating member to rotate.
[0061] Specifically, in this embodiment, the pedal includes a horizontal section and foot pedals located at both ends of the horizontal section. The second rotating member abuts against the horizontal section. The middle position of the second rotating member is connected to the bracket assembly 130 via a rotating shaft. Two rotating connecting rods 123 are respectively located on both sides of the second rotating member.
[0062] Under normal conditions, the two pedals are in a high and low position. When the higher pedal is pressed down, the horizontal section pushes the second rotating component to rotate under the downward action. At this time, the ends of the two rotating connecting rods 123 that are hinged to the second rotating component move up and down respectively, thereby pulling the ends of the two legs with the smaller distance closer to each other, thus realizing the adjustment of the included angle between the two legs.
[0063] Similarly, when it is necessary to reduce the angle between the two outriggers, press down on the lower foot pedal to make the second rotating part rotate in the opposite direction, thereby causing the ends of the two outriggers with the smaller distance to move away from each other, thus achieving the reset of the two outriggers.
[0064] In this embodiment, the support assembly 130 and the leg assembly 120 are hinged together. A locking member 140 is provided at the hinge of the support assembly 130 and the leg assembly 120 to lock the included angle between the support assembly 130 and the leg assembly 120.
[0065] Specifically, in this embodiment, both the support assembly 130 and the leg assembly 120 are provided with insertion holes. When the support assembly 130 is rotated to a preset position, the insertion hole on the support assembly 130 coincides with the insertion hole on the leg assembly 120. At this time, screws or pins can be inserted into the insertion holes to lock the positions of the support assembly 130 and the leg assembly 120, thereby limiting the position of the support assembly 130 and ensuring that the support assembly 130 is stably mounted on the leg assembly 120.
[0066] In addition, in this embodiment, the support assembly 130 is provided with handles. There are two handles and they are symmetrically arranged on both sides of the support assembly 130 so that the handles can be gripped and pushed when the transfer machine is moved.
[0067] In this embodiment, the transfer machine also includes a hand controller. The hand controller has a battery and a controller, and is electrically connected to the drive assembly 310.
[0068] In this embodiment, the hand controller is connected to the drive component 310 via a wire to enable power supply and control of the drive component 310. The hand controller can be set at any position on the bracket component 130 or the leg component 120 to operate the drive component 310.
[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
