Drive assembly 2 comprises first guide rail 201, scissors fork mechanism 202, first fixed horizontal pole 203, connecting rod 204 and electric putter 205, the inboard parallel fixed mounting of accepting board 1 has a set of first guide rail 201, two the lower extreme fixed mounting of first guide rail 201 has first fixed horizontal pole 203, two equal slidable mounting has slider 3 on the first guide rail 201, and connects through connecting rod 204 between two sliders 3, cut fork mechanism 202 upper and lower both ends respectively with connecting rod 204 and first fixed horizontal pole 203 sliding connection, electric putter 205's push rod top and the hinge bar fixed connection who cuts fork mechanism 202. The articulated rod of the scissors mechanism 202 is pushed by the electric push rod 205, so that the scissors mechanism 202 generates parallelogram deformation, the lower end of the scissors mechanism 202 slides simultaneously, the longitudinal stretching and contracting deformation of the crossed rod of the scissors mechanism 202 drives the sliding block 3 to slide along the first guide rail 201, the lifting and descending of the supporting arm 4 are realized, and the armpit of the supporting arm 4 lifting user helps the user to realize the change of sitting and three-dimensional positions. And because the last crossbar deformation of pushing rod promotion scissors fork mechanism 202 can cause adjacent crossbar to deform simultaneously to deformation stack increases at double (one-way diagonal stack removal), and slider 3 lifting efficiency is higher, goes up and down more fast.

In the second embodiment, the difference between the present embodiment and the first embodiment is:

the electric push rod 205 is horizontally and fixedly installed inside the bearing plate 1, and the top end of the electric push rod 205 is fixedly connected with a free end of the lower end of the scissors mechanism 202. Through the stretching of electric putter 205, drive the free end of scissors mechanism 202 lower extreme and keep away from each other or be close to realize scissors mechanism 202 deformation, order about slider 3 and drive support arm 4 and descend or rise.

The third embodiment is different from the first and second embodiments in that:

the driving assembly 2 comprises a control box 211 and a power device 212 arranged in the control box 211, a main rotating wheel 213 is connected to an output shaft of the power device 212, driven wheels 214 are arranged on two sides of the main rotating wheel 213 in a meshed mode, a first screw rod 215 penetrating through and extending to the outside of the sliding block 3 and connected to the bearing plate 1 is arranged in the middle of each driven wheel 214, the two screw rods are in threaded connection with the sliding block 3, the driving wheel is driven to rotate through the power device 212, the two driven wheels 214 are driven to rotate through transmission teeth, the two first screw rods 215 are made to rotate, the sliding block 3 is made to ascend and descend along the two first screw rods 215 to drive the supporting arm 4 to ascend and descend due to the fact that the first screw rods 215 are in threaded connection with.

The fourth embodiment is different from any one of the first to third embodiments in that:

the output shaft of the power equipment 212 is fixedly connected with the second screw rod 221, the second screw rod 221 penetrates through the sliding block 3 and is in threaded connection with the sliding block 3, two second guide rails 222 are fixedly arranged on the inner side of the bearing plate 1 in parallel, the second guide rails 222 penetrate through the sliding block 3, the second screw rod 221 is directly driven to rotate through the power equipment 212, and the second screw rod 221 is in threaded connection with the sliding block 3, so that the sliding block 3 slides up and down along the second guide rails 222 to drive the supporting arm 4 to lift, the output power is strong, and the lifting is stable and powerful.

Fifth, the present embodiment is different from any one of the first to fourth embodiments in that:

the driving assembly 2 is composed of a third guide rail 231, a second fixed cross bar 232, a support frame 233, a driving motor 234, a two-way screw rod 235, a left-handed nut 236 and a right-handed nut 237, two third guide rails 231 are fixedly installed on the bearing plate 1 in parallel, the lower ends of the two third guide rails 231 are respectively fixedly connected with the two ends of the second fixed cross bar 232, the driving motor 234 is slidably installed between the two third guide rails 231 through the support frame 233, the output shaft of the driving motor 234 is fixedly connected with the two-way screw rod 235, the middle parts of the sliding block 3 and the second fixed cross bar 232 are respectively fixedly installed with the left-handed nut 236 and the right-handed nut 237, the two-way screw rod 235 passes through the inner sides of the left-handed nut 236 and the right-handed nut 237, the driving motor 234 drives the two-way screw rod 235 to rotate, and the outer thread at the lower part, make two-way lead screw 235 drive driving motor 234 and slide along third guide rail 231, the upper portion interact of levogyration nut 236 and two-way lead screw 235 at the same time slider 3 middle part, make slider 3 along two-way lead screw 235 activity, the slider drives the lift of support arm 4, because the rotation of two-way lead screw 235 orders about levogyration nut 236 and dextrorotation nut 237 and is relative (reverse) motion, make the relative second of slider 3 fix the horizontal pole 232 the velocity of motion 2 times of one-way lead screw, promote the efficiency of the up-and-down motion of support arm 4, thereby more efficient completion is sat, the change of three-dimensional position.

In addition, the supporting arm 4 in embodiments 1-5 can achieve proper extension and retraction of the length of the supporting arm 4 by using a telescopic mechanism (such as an electric telescopic rod, an electric slide rail, etc.) in the prior art, so as to adapt to the change of the transverse position of the armpit supporting point caused by the change of the sitting position and the three-dimensional position, and be more convenient for the user to use.

The control of the device can adopt the control modes of key control or AI intelligence and the like in the prior art, the control technology is the content already disclosed in the prior art, and the technical scheme is not described in detail.

The working principle is as follows:

the device is firstly fixed at the installation position required by the corresponding place, a hanging or fixed installation mode can be adopted, meanwhile, the fixing support 10 can be connected with the bearing plate 1, the device is pushed to the appointed installation position, and the position of the device is fixed by the fixing caster 13.

The drive assembly 2 works to enable the sliding block 3 to drive the supporting arm 4 to move to the armpit corresponding height of the standing position of the user, then the armpit is put at the front end of the supporting arm 4, namely, the armpit supporting point, the sliding block 3 is driven to slide downwards through the drive assembly 2, the sliding block 3 drives the supporting arm 4 to descend to enable the user to be in a stable sitting posture, and the user can freely do required activities by both hands in the process. In the same way, the driving component 2 drives the supporting arm 4 to rise through the sliding block 3, so that the armpit of the user is lifted, and the user can easily and stably stand.

Although embodiments of the present invention have been shown and described in the description of the present invention, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made herein without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
