[0037] like Figures 1-4 As shown, the embodiment of the present application provides an electric lifting device, including a skeleton 1, the skeleton 1 includes a first wheel frame 11, a second wheel frame 12, a first connecting plate 13, a vertical rod 14, a sleeve rod 15 and a second connecting plate 16, the first wheel frame 11 and the second wheel frame 12 are in a "Z" shape, the first wheel frame 11 and the second wheel frame 12 are connected by the first connecting plate 13, the first connecting plate 13 is installed with at least two vertical rods 14 arranged in parallel and spaced apart, one end of each vertical rod 14 is connected to the first connecting plate 13, and the other end is movably sleeved with the sleeve rod 15, the first wheel frame 11, the second wheel frame 12 and the first connecting plate 13 are horizontally arranged, the first connecting plate 13 is located between the first wheel frame 11 and the second wheel frame 12, and the upper end of each sleeve rod 15 is fixedly connected to the second connecting plate 16;

[0038] Back plate 2, back plate 2 is fixedly sleeved on the outside of sleeve rod 15;

[0039] The load-bearing plate 3 is connected to the back plate 2, and the load-bearing plate 3 and the back plate 2 are detachably connected;

[0040] Armrests 4, the number of armrests 4 is at least two, the armrests 4 are arranged on both sides of the backboard 2, and one end of the armrest 4 is connected to the backboard 2 through a rotating mechanism 6;

[0041] The driving mechanism 5 is mounted on the surface of the first connecting plate 13 and is used to drive the sleeve rod 15 to move up and down;

[0042] The roller groups are respectively mounted on the ends of the first wheel frame 11 and the second wheel frame 12 .

[0043] In this embodiment, the cross-sectional shape of the first wheel frame 11, the second wheel frame 12 and the vertical rod 14 is a regular quadrilateral, and optionally, it can also be a circle, an ellipse and a regular polygon, etc. The shape of the sleeve rod 15 matches the shape of the vertical rod 14, the vertical rod 14 is vertically arranged, and the vertical rod 14 is detachably fixed to the first connecting plate 13 by bolts, and the upper end of the vertical rod 14 is tilted at a preset angle relative to the vertical plane where the vertical rod 14 is located toward the side away from the load-bearing plate 3, and the preset angle is 4°-10°. By setting a certain tilt angle, when the user sits on the load-bearing plate, the user's forward leaning tendency can be offset or partially offset, thereby preventing the user from falling forward, making the electric assisted lifting device of the present application safer and more reliable;

[0044] There are two vertical poles 14. The arrangement of the two vertical poles 14 can improve stability when the driving mechanism 5 drives the sleeve rod 15 and the bearing plate 3 to move up and down. In addition, the first wheel frame 11 and the second wheel frame 12 are both in a "Z" shape. This arrangement increases the horizontal width of the first wheel frame 11 and the second wheel frame 12. When the equipment turns, the stability of the structure can be further increased, which can effectively prevent rollover.

[0045] The back panel 2 includes a front guard plate 21 and a rear guard plate 22, which are detachably connected by bolts. The load-bearing plate 3 can be set parallel to the ground or tilted toward the ground. When tilted, the load-bearing plate 3 is 50 mm above the ground at its lowest point, making it easy for people to move onto the load-bearing plate. Handrails 4 are provided on both sides of the back panel 2.

[0046] The driving mechanism 5 can drive the sleeve rod 15 to slide up and down on the surface of the vertical rod 14, thereby driving the bearing plate 3 to achieve the purpose of rising and falling. The driving mechanism 5 is arranged on the side away from the bearing plate 3, so that the purpose of balanced counterweight can be achieved, making the lifting equipment more stable during movement;

[0047] The setting of the roller group allows the lifting equipment to move flexibly;

[0048] By setting up two vertical poles 14, when the driving mechanism 5 drives the sleeve rod 15 and the load-bearing plate 3 to move up and down, the vertical stability can be improved. The first wheel frame 11 and the second wheel frame 12 are designed to be in a "Z" shape. In this way, when the equipment turns, the horizontal stability can be further increased, which can effectively prevent rollover.

[0049] In one embodiment, with the plane where the vertical pole 14 is located as a reference, the load-bearing plate 3 is located on one side of the plane, and the distance between the ends of the first wheel frame 11 and the second wheel frame 12 on the same side as the load-bearing plate 3 is greater than the distance between the ends of the first wheel frame 11 and the second wheel frame 12 on the other side of the plane.

[0050] In this embodiment, through such an arrangement, the first wheel frame 11 and the second wheel frame 12 form an "eight" shape, which can further improve stability. At the same time, when the personnel are doing standing and moving training (the load-bearing plate 3 needs to be removed at this time), the legs have more room to move, and the first wheel frame 11 and the second wheel frame 12 will not affect the personnel. Among them, there is an angle between the first wheel frame 11 and the second wheel frame 12 located on the same side as the load-bearing plate 3 and the side of the load-bearing plate 3, which can further improve stability and provide more room for movement.

[0051] In one embodiment, first handles 161 are provided on both sides of the second connecting plate 16 , and second handles 23 are provided on both sides of the rear guard plate 22 of the back plate 2 . The first handles 161 and the second handles 23 are arranged in an upper and lower spaced relationship.

[0052] In this embodiment, by providing handles at different heights, the first handle 161 can be used when the equipment is pushed after the load-bearing plate 3 is lowered, and the second handle 23 can be used when a person stands up or does standing training.

[0053] In one embodiment, it also includes a first universal wheel 7 and a second universal wheel 9. The size of the first universal wheel 7 is smaller than or equal to the size of the second universal wheel 9. The first universal wheel 7 is installed at the end of the first wheel frame 11 and the second wheel frame 12 at the end with a larger distance between them. The second universal wheel 9 is installed at the end of the other end of the first wheel frame 11 and the second wheel frame 12 through the third mounting member 8.

[0054] In this embodiment, the setting of the first universal wheel 7 and the second universal wheel 9 can greatly improve the flexibility of the lifting equipment, so that the equipment can achieve flexible multi-directional steering during movement. The setting of the larger second universal wheel 9 can further improve the load-bearing capacity.

[0055] In one embodiment, the ends of the first wheel frame 11 and the second wheel frame 12 on which the first universal wheel 7 is mounted are covered with protective covers 111 .

[0056] In this embodiment, the provision of the protective cover 111 can effectively prevent collisions. In addition, the protective cover 111 is made of a relatively soft rubber material, which can reduce the vibration when a collision occurs.

[0057] In one embodiment, the second universal wheel 9 is equipped with a locker 91 .

[0058] In this embodiment, the locker 91 can lock and unlock the second universal wheel 9. When it does not need to be moved, the second universal wheel 9 can be locked. At this time, the lifting equipment is locked and cannot move. When it needs to be moved, the locker 91 is unlocked and the lifting equipment can be moved.

[0059] In one embodiment, the driving device includes an electric telescopic rod 51, a motor 52 and a power supply 53. The motor 52 is installed on the surface of the first connecting plate 13. One end of the electric telescopic rod 51 is transmission-connected to the motor 52, and the other end is hinged to the second connecting plate 16. The power supply 53 is installed on the side wall of the electric telescopic rod 51.

[0060] In this embodiment, the power supply 53 includes a battery and a charger, which form an integrated box body. The power supply 53 provides power to the motor 52. The motor 52 drives the electric telescopic rod 51 to extend and retract, thereby driving the second connecting plate 16 to move up and down, and driving the sleeve rod 15 and the load-bearing plate 3 to be raised and lowered. Among them, the electric telescopic rod 51 adopts a 24V safety voltage and a thrust of 3000N.

[0061] like Figure 5 As shown, in one embodiment, a controller 42 is provided at the other end of the armrest 4 , the controller 42 is electrically connected to the motor 52 , and the controller 42 is provided with a rocker 43 .

[0062] In this embodiment, the controller 42 can control the rotation of the motor 52. Specifically, by setting a joystick 43, when the joystick 43 is pushed upward, the controller 42 sends an instruction to the motor 52, and the motor 52 drives the electric telescopic rod 51 to extend, driving the sleeve rod 15 and the load-bearing plate 3 to rise. Conversely, when the joystick 43 is pushed downward, the motor 52 drives the electric telescopic rod 51 to retract, driving the sleeve rod 15 and the load-bearing plate 3 to descend.

[0063] like Figure 6 As shown, in one embodiment, at least one connecting rod 31 is provided at the bottom of the load-bearing plate 3, and a first mounting member 32 is provided at the bottom of the back plate 2. Through holes are provided on the side walls of the connecting rod 31 and the first mounting member 32. One end of the connecting rod 31 is inserted into the first mounting member 32. When the pin 33 passes through the through holes on the connecting rod 31 and the first mounting member 32 at the same time, the connecting rod 31 is connected to the first mounting member 32.

[0064] In this embodiment, the first mounting member 32 is tubular, and the cross-sectional shape is a regular quadrilateral. Optionally, it can also be circular, elliptical, polygonal, etc. One end of the first mounting member 32 is fixedly connected to the bottom of the back plate 2, and the other end is plugged into the connecting rod 31. The connecting rod 31 is "L"-shaped, and the cross-sectional shape is adapted to the first mounting member 32.

[0065] During installation, insert the mounting end of the connecting rod 31 into the first mounting member 32 so that the through hole on the connecting rod 31 overlaps with the through hole on the first mounting member 32. At this time, insert the pin 33 into the through hole and pass through the connecting rod 31 and the first mounting member 32 to complete the installation of the load-bearing plate 3.

[0066] In one embodiment, a flexible strip 331 is provided at one end of the latch 33 , one end of the flexible strip 331 is fixedly connected to the latch 33 , and a collar 332 is provided at the other end of the flexible strip 331 .

[0067] In this embodiment, the ring 332 is an elastic rubber ring that can be sleeved on the surface of the pin 33. Specifically, when the pin 33 passes through the through holes on the connecting rod 31 and the first mounting member 32 at the same time, the load-bearing plate 3 is installed. At this time, the ring 332 is sleeved on the other end of the pin 33. Under the action of the elastic force of the ring 332, it is sleeved on the pin 33, and the pin 33 and the flexible strip 331 form a closed loop. At this time, it can effectively prevent the pin 33 from disengaging from the through hole during movement, causing the connecting rod 31 to disengage from the first mounting member 32, and can further improve the stability of the connection between the connecting rod 31 and the first mounting member 32.

[0068] like Figure 7 As shown, in one embodiment, the rotating mechanism 6 includes a second mounting member 61, a limiting plate 62 and a sliding rod 63. One end of the second mounting member 61 is fixedly connected to the first mounting member 32, and the other end is rotatably connected to the armrest 4. The limiting plate 62 is fixedly sleeved on the outer wall of the second mounting member 61. At least one arc-shaped sliding rail 621 is provided on the edge of the limiting plate 62. One end of the sliding rod 63 is fixedly mounted on the side of the armrest 4 close to the limiting plate 62, and the other end extends into the sliding rail 621 and can slide in the sliding rail 621.

[0069] In this embodiment, the armrest 4 is rotatably connected to the end of the second mounting member 61 by a bolt, so that the armrest 4 can rotate in the vertical direction around the bolt. The limiting plate 62 is disc-shaped, and an arc-shaped slide rail 621 is provided on the edge of the limiting plate 62. A first groove 6211 and a second groove 6212 are provided at both ends of the slide rail 621. The first groove 6211 and the second groove 6212 correspond to the deployed state (i.e., the second groove 6212) and the retracted state (i.e., the first groove 6211) of the armrest 4, respectively. The retracted end of the slide rail 621 is located above the deployed end. In addition, the slide rail 621 can also limit the rotation angle of the armrest 4.

[0070] By means of the provided rotating mechanism 6, the armrest 4 can be rotated downward by the rotating mechanism 6 when it is needed, so that the armrest 4 forms a certain angle with the backboard 2. The downwardly rotated armrest 4 is now located on both sides of the load-bearing plate 3. During the movement, the armrest 4 can protect the person and prevent the person from tilting. When it is not needed, the armrest 4 is rotated upward by the rotating mechanism 6, so that the armrest 4 is parallel to the backboard 2 and the sleeve rod 15, which can greatly save space. Optionally, a soft packing 41 is further provided on the surface of the armrest 4 to improve the comfort of the person.

[0071] Specifically, taking the folded state as an example, the slide bar 63 is located in the first groove 6211 of the slide rail 621. When in use, the armrest 4 rotates downward around the connection point of the bolt, driving the slide bar 63 to slide from the first groove 6211 toward the second groove 6212. When the slide bar 63 slides to the second groove 6212, the armrest 4 is unfolded. At this time, the second groove 6212 can also limit the slide bar 63 to prevent the slide bar 63 from continuing to slide, thereby keeping the armrest 4 in the unfolded state. Conversely, when it needs to be folded, the armrest 4 is rotated in the opposite direction so that the slide bar 63 returns to the first groove 6211. At this time, the first groove 6211 also limits the slide bar 63 to prevent the slide bar 63 from continuing to slide, thereby keeping the armrest 4 in the folded state.

[0072] In one embodiment, a protective shell 64 is provided on the outside of the rotating mechanism 6. The provision of the protective shell 64 can prevent hands from being pinched when the armrest 4 is rotated, thereby improving safety.

[0073] In one embodiment, a hook 611 is installed on the side wall of the second mounting member 61 .

[0074] In this embodiment, the second mounting members 61 on both sides of the back plate 2 are provided with hooks 611 , which are used for connecting safety belts, thereby further improving safety.

[0075] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
