When it is necessary to help users such as the elderly and paralyzed patients to move and stand up for rehabilitation, the users cannot stand up directly by themselves. The driving member drives the lifting column to descend relative to the column to drive the seat assembly to descend. After the seat assembly descends to a suitable position (for example, the seat assembly descends to the lowest point), the user is allowed to sit on the seat assembly. The lifting column is then driven to rise relative to the column by the driving member to drive the seat assembly to rise, thereby causing the user's center of gravity to rise accordingly until the user is close to a standing posture, or the user can already achieve a standing posture. After that, the user can move by holding or pushing the electric assisted lifting device, thereby enabling the user to stand, walk, or perform rehabilitation training through the electric assisted lifting device. In addition, in the prior art, when a user sits on the seat assembly, the user has a tendency to lean forward, and the user is likely to fall from the seat assembly. However, since the column of the present application is tilted at a preset angle relative to the support assembly toward the side away from the seat assembly, and the lifting column is coaxially sleeved on the column, the column and the lifting column of the present application have a preset angle of tilting backward, so that when the user sits on the seat assembly, the user's tendency to lean forward can be offset or partially offset, thereby preventing the user from falling forward from the seat assembly, making the electric assisted lifting equipment of the present application safer and more reliable.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In addition, "and / or" in the full text includes three solutions. Taking A and / or B as an example, it includes A technical solution, B technical solution, and A and B technical solutions that meet both requirements. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0049] The specific structure of the electric auxiliary lifting equipment will be mainly described below.

[0050] like Figure 1-3 As shown, an electric assisted lifting device includes a support assembly 100, a column 200, a lifting column 300 and a driving member 500. The column 200 is arranged on the support assembly 100, the lifting column 300 is coaxially sleeved on the column 200, the lifting column 300 can be lifted and lowered along the axial direction of the column 200, the seat assembly 400 is connected to the lifting column 300, and the driving member 500 is arranged on the support assembly 100. The driving member 500 is used to drive the lifting column 300 to rise and fall relative to the column 200, so as to drive the seat assembly 400 to rise and fall; the column 200 is inclined at a preset angle relative to the support assembly 100 toward a side away from the seat assembly 400.

[0051] When it is necessary to help elderly people, paralyzed patients and other users to move or stand up for rehabilitation, the users cannot stand up directly by themselves, and the driving member 500 drives the lifting column 300 to descend relative to the column 200 to drive the seat assembly 400 to descend. After the seat assembly 400 descends to a suitable position (for example, the seat assembly 400 descends to the lowest point), the user is allowed to sit on the seat assembly 400, and then the driving member 500 drives the lifting column 300 to rise relative to the column 200 to drive the seat assembly 400 to rise, thereby causing the user's center of gravity to rise accordingly, until the user is close to a standing posture, or the user can already achieve a standing posture, after which the elderly, paralyzed patients and other users can move by holding or pushing the electric-assisted lifting device, so that the user's standing, walking, or rehabilitation training is achieved through the electric-assisted lifting device. In addition, in the prior art, when a user sits on the seat assembly 400, the user tends to lean forward, so that the user is likely to fall from the seat assembly 400. However, since the column 200 of the present application is inclined at a preset angle relative to the support assembly 100 toward a side away from the seat assembly 400 (see Figure 2 ), and the lifting column 300 is coaxially sleeved on the column 200, so that the column 200 and the lifting column 300 of the present application have a preset angle of tilting backward, so that when the user sits on the seat assembly 400, the user's forward tilting tendency can be offset or partially offset, thereby preventing the user from falling forward from the seat assembly 400, making the electric assisted lifting equipment of the present application safer and more reliable.

[0052] In this embodiment, the driving member 500 is an electric push rod, which uses a 24V safety voltage and has a thrust of 3000 N. In this embodiment, the electric push rod is disposed on the support assembly 100, and one end of the push rod of the electric push rod away from the support assembly 100 is connected to the lifting column 300, so that the extension and retraction of the push rod can drive the lifting column 300 to rise and fall.

[0053] Optionally, the number of the columns 200 is one or two, and the number of the lifting columns 300 is the same as that of the columns 200, and they correspond one to one. Figure 1 , Figure 3 and Figure 7 , when the number of the columns 200 is one, the electric auxiliary lifting equipment is a single column structure; Figure 8-9 When the number of the columns 200 is two, the electric-assisted lifting device is a double-column structure. The working principles of the electric-assisted lifting devices of the single-column structure and the double-column structure are the same, except that the number and arrangement of the columns and the structures connected with the columns are different.

[0054] Optionally, the preset angle is 4°-10°. In this embodiment, the preset angle is 5° or 6°. When the preset angle is 5° or 6°, the effect is the best. If the preset angle is too small, it will basically have no effect and cannot offset the user's forward leaning tendency. If the preset angle is too large, it will be counterproductive and cause the user to fall backwards.

[0055] The double column structure has better load-bearing capacity and stability than the single column structure. Among them, the lifting height of the single column structure is 500mm and the load is 300LB, while the lifting height of the double column structure is 760mm and the load is 400LB.

[0056] refer to Figure 1 and Figure 8 , the column 200 is a square tube, and the lifting column 300 is also a square tube. Specifically, the square tube has high up and down stability and is commonly used in the material market.

[0057] refer to Figure 10-11 , a friction sleeve 600 is provided between the column 200 and the lifting column 300. Specifically, the provision of the friction sleeve 600 can avoid direct contact friction between the column 200 and the lifting column 300, thereby avoiding wear of the column 200 and / or the lifting column 300. In this embodiment, the friction sleeve 600 is fixed to the inner side of the lifting column 300, and the friction sleeve 600 is slidably sleeved on the outer periphery of the lifting column 300, so that the column 200 and the lifting column 300 are slidably matched, so that the lifting column 300 can be lifted and lowered along the axial direction of the column 200.

[0058] refer to Fig.11 The friction sleeve 600 has a guide protrusion 610, and a group of guide blocks 210 are arranged at one end of the column 200 that cooperates with the lifting column 300. The group of guide blocks 210 includes two guide blocks 210 arranged at intervals. The guide protrusion 610 can be accommodated between the two guide blocks 210 of the group of guide blocks 210, thereby guiding the lifting column 300. Specifically, the number of guide protrusions 610 is multiple, and multiple groups of guide blocks 210 are arranged at one end of the column 200 that cooperates with the lifting column 300. Each guide protrusion 610 corresponds to a group of guide blocks 210. In this embodiment, the number of guide protrusions 610 is four, and the four guide protrusions 610 are located in the middle of the four inner side walls of the friction sleeve 600, and the four groups of guide blocks 210 are located at the four outer side walls of the end of the column 200 that cooperates with the lifting column 300.

[0059] In this embodiment, the friction sleeve 600 is made of POM material, where POM refers to polyoxymethylene resin.

[0060] refer to Figure 12-13In other embodiments, the electric auxiliary lifting equipment is not provided with the friction sleeve 600. The first guide wheel 220 is provided at one end of the column 200 that cooperates with the lifting column 300, and the second guide wheel 310 is provided at one end of the lifting column 300 that cooperates with the column 200. The first guide wheel 220 and the lifting column 300 are in rolling cooperation, and the second guide wheel 310 and the column 200 are in rolling cooperation. Specifically, the provision of the first guide wheel 220 and the second guide wheel 310 can, on the one hand, avoid direct contact friction between the column 200 and the lifting column 300, thereby avoiding wear of the column 200 and / or the lifting column 300, and on the other hand, can play a guiding role for the lifting column 300.

[0061] Specifically, the number of the first guide wheel 220 and the number of the second guide wheel 310 are both plural. In the present embodiment, the number of the first guide wheel 220 and the second guide wheel 310 are both four. The four outer side walls of one end of the column 200 that cooperates with the lifting column 300 are provided with four first openings 230. The four first guide wheels 220 are rotatably disposed at the four first openings 230 of the column 200. The four outer side walls of one end of the lifting column 300 that cooperates with the column 200 are provided with four second openings 320. The four second guide wheels 310 are rotatably disposed at the second openings 320 of the lifting column 300, so that the first guide wheel 220 and the lifting column 300 are rollingly matched, and the second guide wheel 310 and the column 200 are rollingly matched.

[0062] refer to Figure 1 and Figure 6 The support assembly 100 includes a support plate 110 and a first rectangular tube 120 and a second rectangular tube 130 vertically arranged at both ends of the support plate 110. The column 200 is arranged on the support plate 110, and the column 200 is arranged vertically relative to the plane formed by the support plate 110, the first rectangular tube 120 and the second rectangular tube 130. Specifically, when the equipment is placed on the ground, the axes of the first rectangular tube 120 and the second rectangular tube 130 are parallel to the horizontal direction, and the first rectangular tube 120 and the second rectangular tube 130 are both rectangular tubes, so that the first rectangular tube 120 and the second rectangular tube 130 have two side walls in addition to the top wall and the bottom wall, and the two side walls have a supporting and bearing function for the top wall. The existence of the two side walls makes the supporting function of the first rectangular tube 120 and the second rectangular tube 130 more reliable and can bear a larger load. In addition, the weight of the first rectangular tube 120 and the second rectangular tube 130 is lighter than that of a whole bottom plate.

[0063] refer to Figure 1 , Figure 6 and Figure 8, a reinforcing rib 140 is provided between the column 200 and the support plate 110. Specifically, the provision of the reinforcing rib 140 can strengthen the connection strength between the column 200 and the support plate 110. In this embodiment, the reinforcing rib 140 is welded to the top surface of the support plate 110, and the reinforcing rib 140 is welded to the side of the column 200.

[0064] refer to Figure 6 The number of the reinforcing ribs 140 is multiple, which further strengthens the connection strength between the column 200 and the support plate 110. In this embodiment, the number of the reinforcing ribs 140 is two, and the two reinforcing ribs 140 are arranged at intervals.

[0065] refer to Figure 1 and Figure 5-6 The support assembly 100 further includes a first rotating wheel 150 and a second rotating wheel 160. The first rotating wheel 150 is rotatably disposed on the first rectangular tube 120, and the second rotating wheel 160 is rotatably disposed on the second rectangular tube 130. Specifically, the arrangement of the first rotating wheel 150 and the second rotating wheel 160 facilitates the transfer of the electric auxiliary lifting device.

[0066] Furthermore, the distance from the rotation axis of the first rotating wheel 150 and the second rotating wheel 160 to the bottom surface of the first rectangular tube 120 is greater than the radius of the first rotating wheel 150 and the second rotating wheel 160, so that when the equipment is placed on the ground so that the bottom surfaces of the first rectangular tube 120 and the second rectangular tube 130 are in contact with the ground, the first rotating wheel 150 and the second rotating wheel 160 are not in contact with the ground. This arrangement enables the equipment to be stably placed on the ground to prevent the equipment from slipping and moving; when the equipment needs to be transferred, the equipment is pressed downward toward the side close to the first rotating wheel 150 and the second rotating wheel 160 so that the first rotating wheel 150 and the second rotating wheel 160 are in contact with the ground, and the side of the equipment away from the first rotating wheel 150 and the second rotating wheel 160 is tilted, thereby facilitating the transfer of the equipment.

[0067] The first rotating wheel 150 is rotatably disposed at the rear side of the first rectangular tube 120, and the second rotating wheel 160 is rotatably disposed at the rear side of the second rectangular tube 130. Specifically, the side of the seat plate 420 away from the column 200 is used as the front side of the device, and the side of the column 200 away from the seat plate 420 is used as the rear side of the device. In this way, the first rotating wheel 150 and the second rotating wheel 160 are both disposed at the rear side of the support assembly 100, so that when the device needs to be transferred, the device is pressed down from the rear side to make the front side of the device tilt up, and at this time, the first rotating wheel 150 and the second rotating wheel 160 contact the ground, so as to facilitate the transfer of the device.

[0068] refer to Figure 5-6The first rectangular tube 120 has a first extension portion 121 on the side facing the second rectangular tube 130, and the second rectangular tube 130 has a second extension portion 131 on the side facing the first rectangular tube 120. The first rectangular tube 120 and the second rectangular tube 130 are connected to the support plate 110 through the first extension portion 121 and the second extension portion 131.

[0069] refer to Figure 1 and Figure 5-6 The first extension part 121 and the second extension part 131 are connected to the support plate 110 by screws 170, so that the column 200 and the first rectangular tube 120 and the second rectangular tube 130 are detachable, saving transportation packaging space. Specifically, there are multiple screws 170, so that the first extension part 121 and the second extension part 131 can be more reliably connected to the support plate 110.

[0070] In one embodiment, a plurality of screws 170 pass through the support plate 110 from the top surface of the support plate 110 and extend into the first extension portion 121 and the second extension portion 131 , thereby achieving a reliable connection between the first extension portion 121 and the second extension portion 131 and the support plate 110 . In this embodiment, a plurality of screws 170 pass through the support plate 110 from the top surface of the support plate 110 and extend into the first extension portion 121 and the second extension portion 131; a plurality of screws 170 also pass through the support plate 110 from the rear side surface of the support plate 110, and a portion of the screws 170 extend into the first extension portion 121, and a portion of the screws 170 extend into the second extension portion 131, thereby further improving the reliability of the connection between the first extension portion 121 and the second extension portion 131 and the support plate 110. With such an arrangement, even if all the screws 170 passing through the top surface of the support plate 110 are damaged and fail, the rear side surface of the support plate 110 will not tilt up due to the support of the screws 170 passing through the rear side surface of the support plate 110, and thus the seat assembly 400 and the user sitting on the seat assembly 400 will not fall forward.

[0071] refer to Figure 1 and Figure 6 , the support plate 110 is a Z-shaped structure, the support plate 110 has a notch 111, and the column 200 is arranged at the notch 111 of the support plate 110 and connected to the support plate 110 of the Z-shaped structure. Specifically, the support plate 110 is arranged in a Z-shaped structure, so that in addition to the bottom surface of the column 200 being in contact and connection with the top surface of the support plate 110, the side surface of the column 200 at the notch 111 can also be in contact and connection with the side wall of the two top surfaces of the Z-shaped structure of the support plate 110, thereby increasing the contact area between the column 200 and the support plate 110, and further making the connection between the column 200 and the support plate 110 more stable and reliable.

[0072] In this embodiment, the column 200 and the support plate 110 are connected by welding.

[0073] refer to Figure 1 The seat assembly 400 includes a connecting frame 410, a seat plate 420 and two armrests 430. The connecting frame 410 is fixedly connected to the lifting column 300, the seat plate 420 is connected to the connecting frame 410, and the two armrests 430 are connected to opposite sides of the connecting frame 410. Specifically, the two armrests 430 are provided so that when a user sits on the seat plate 420, he can hold the armrests 430 with both hands, so that the user can sit on the seat plate 420 more stably, and after being lifted to a desired height, the user can support himself with both hands on the armrests 430, so that the user can stand up.

[0074] refer to Figure 1 The seat assembly 400 further includes a back plate 440, which is disposed on the connecting frame 410. The back plate 440 and the seat plate 420 have a certain angle. The back plate 440 is disposed so that when a user sits on the seat plate 420, the back of the user can lean against the back plate 440, making the user safer and more comfortable. In one embodiment, the back plate 440 and the seat plate 420 have a 90-degree angle.

[0075] The armrest 430 is hinged to the connecting frame 410, and the armrest 430 can be rotated relative to the connecting frame 410 to flip up the armrest 430; specifically, when the user needs to sit on the seat panel 420, the armrest 430 can be flipped up, so that the user can sit on the seat panel 420 not only from the front of the seat panel 420, but also from both sides of the seat panel 420, and when the user sits on the seat panel 420 from the front of the seat panel 420, the user can avoid colliding with the armrest 430, thereby improving the convenience of the user sitting on the seat panel 420.

[0076] Specifically, when in use, the armrest 430 is in a horizontally arranged use state, and after the armrest 430 is flipped up, the armrest 430 is in a vertically arranged flipped up state.

[0077] refer to Figure 1 and Figure 3-4 The seat assembly 400 further includes a limiting structure 450, which is used to limit the rotation angle of the armrest 430 to prevent the position of the armrest 430 from changing when the user grasps the armrest 430, thereby preventing the user from falling. Specifically, the setting of the limiting structure 450 enables the limiting structure 450 to provide an upward supporting force to the armrest 430 when the armrest 430 is in a horizontally set use state, so that the armrest 430 will not continue to rotate downward.

[0078] refer to Figure 1 and Figure 4The limiting structure 450 includes a bottom panel 451 and two side panels 452 spaced apart on the bottom panel. The bottom panel 451 and the two side panels 452 form a semi-accommodating space. When the armrest 430 is turned down into the semi-accommodating space, the bottom panel 451 provides an upward supporting force to the armrest 430, so that the armrest 430 cannot continue to rotate downward, so that the armrest 430 can provide reliable supporting force to the user.

[0079] refer to Figure 1 , the side of the seat plate 420 away from the column 200 and the left and right sides of the seat plate 420 are provided with downwardly inclined extension plates 421, thereby forming a slope.
