Technical Field

[0001] This utility model relates to the field of upper limb assistive device technology, specifically, to an upper limb assistive device. Background Technology

[0002] In warehouses and factories, workers often need to use their upper limbs to carry out handling tasks, which requires them to raise their upper limbs for long periods of time or frequently. This can easily lead to excessive fatigue of the upper limbs or joint damage. Such long-term, high-intensity handling work can cause significant harm to the human body.

[0003] For example, patent CN219235289U discloses an upper limb assistive device, including: a fixed component installed on an external mechanism; an active rotating component disposed on the fixed component; an adjusting mechanical component disposed on the active rotating component; and a supporting component disposed on the adjusting mechanical component for supporting the upper limb; the adjusting mechanical component and the fixed component are both rotatably connected to the active rotating component via connecting shafts; the upper limb drives the adjusting mechanical component and the supporting component to adjust the spatial position of the supporting component; the supporting component drives the adjusting mechanical component to adjust the pitch and yaw angles of the supporting component. Although this upper limb assistive device can assist the upper limb in completing carrying tasks, reduce the load on the upper limb, and alleviate fatigue, in actual use, the upper limb assistive device cannot be adjusted according to the length of the worker's upper limb, resulting in inconvenience for the worker when performing carrying tasks. Utility Model Content

[0004] In view of the deficiencies in the existing technology, this utility model provides an upper limb assistive device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An upper limb assistive device includes an assistive device body, which includes an adjustment mechanism and a mounting rod disposed on the adjustment mechanism. The mounting rod has a mounting cavity with one end open along its length. A movable rod with one end extending out of the mounting cavity and slidable is disposed in the mounting cavity. A box is disposed on the side wall of the mounting rod, and a cavity is disposed inside the box. A positioning component for positioning the movable rod is disposed in the cavity. A rotatable support plate is hinged to the extended end of the movable rod.

[0007] Preferably, the moving rod has a plurality of positioning holes evenly distributed along its length; the positioning assembly includes a driving block disposed in the cavity, the driving block is provided with a positioning rod that penetrates the mounting rod and is inserted into the corresponding positioning hole, the side wall of the cavity is provided with a spring for always pushing the driving block to insert one end of the positioning rod into the corresponding positioning hole, and the cavity is also provided with a moving part for pushing the driving block to move and causing one end of the positioning rod to disengage from the corresponding positioning hole.

[0008] Preferably, the side wall of the box body has a connecting groove along its length to connect the cavity, and the end wall of the drive block has a first inclined surface; the moving part also includes a moving block that can be slidably disposed in the cavity, the moving block has a second inclined surface that cooperates with the first inclined surface, and the moving block has a lever with one end extending out of the connecting groove. The lever drives the moving block to slide along the connecting groove, and drives the second inclined surface to press the first inclined surface so that the drive block drives one end of the positioning rod to disengage from the corresponding positioning hole.

[0009] Preferably, the side wall of the drive block is provided with a limiting plate for abutting against the side wall of the cavity to limit the movement of the drive block.

[0010] Preferably, the side wall of the mounting cavity is provided with a groove along its length, the side wall of the moving rod is provided with a protrusion that fits into the groove at one end, and the opening of the mounting cavity is provided with a blocking ring for intercepting the protrusion.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the arrangement of an installation rod, an installation cavity, a moving rod, a box body, a cavity, a positioning component, and a support plate, allows the moving rod to extend along the installation cavity, thereby adjusting the position of the support plate. The moving rod is then positioned by the positioning component installed in the cavity, thus fixing the position of the support plate. Compared with existing models, this utility model can adjust the position of the support plate according to the position of the worker's upper limbs, making it easier for workers to use and for handling goods.

[0016] 2. This utility model, through the setting of a fixed ring, a rotating cylinder, and a limiting ring, allows the rotating cylinder to be clamped by twisting the limiting ring. When the limiting ring clamps the rotating cylinder, the rotating cylinder cannot rotate, that is, the bearing plate cannot rotate, thus enabling the worker's upper limbs to stably transport goods through the bearing plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution:

[0028] like Figure 1As shown, an upper limb assistive device in this embodiment includes an assistive device body 100. The assistive device body 100 includes an adjustment mechanical component 110 and a mounting rod 120 disposed on the adjustment mechanical component 110. A mounting cavity 201 with one end open is formed in the mounting rod 120 along its length direction. A movable rod 130 with one end extending out of the mounting cavity 201 and slidable is disposed in the mounting cavity 201. A box 140 is provided on the side wall of the mounting rod 120. A cavity 301 is provided in the box 140. A positioning component for positioning the movable rod 130 is provided in the cavity 301. A rotatable support plate 150 is hinged to the extended end of the movable rod 130.

[0029] In this embodiment, the power assist body 100 raises one end of the mounting rod 120 by adjusting the output torque generated by the mechanical component 110. The raising of the mounting rod 120 drives the support plate 150 on the moving rod 130 to rise, so that when the upper limb placed on the support plate 150 is performing a carrying operation, the output torque generated by the adjusting mechanical component 110 can offset part of the gravity on the upper limb, thereby reducing the load on the upper limb and relieving upper limb fatigue.

[0030] The booster body 100 and the adjustment mechanical component 110 adopt the structure of the patent with patent number CN219235289U, so they will not be explained further.

[0031] The movable rod 130 slides out along the mounting cavity 201, allowing the support plate 150 mounted on the movable rod 130 to be moved and adjusted to the position of the support plate 150 so that it is aligned with the upper limb of the worker. Then, the positioning component in the cavity 301 positions the adjusted movable rod 130 so that the movable rod 130 always maintains the adjusted length, thus adapting to the upper limb of the worker and making it highly practical.

[0032] Among them, the bearing plate 150 is hinged to the positioning rod 320, so that when the worker's upper limbs are placed on the bearing plate 150, the worker can move the bearing plate 150 by using his upper limbs to pick up and put down goods, which makes it more convenient to pick up and put down goods.

[0033] In actual use, the position of the support plate 150 is adjusted by the extension of the moving rod 130 along the mounting cavity 201. The position of the moving rod 130 is fixed by the positioning component installed in the cavity 301. Compared with the existing ones, this utility model can adjust the position of the support plate 150 according to the position of the worker's upper limb, which makes it easier for the worker to use the upper limb assist device and is more convenient when carrying goods.

[0034] like Figure 1-2As shown, in this embodiment, a groove 202 is provided on the side wall of the mounting cavity 201 along its length direction, and a protrusion 212 with one end inserted into the groove 202 is provided on the side wall of the moving rod 130. A blocking ring 220 for intercepting the protrusion 212 is provided at the opening of the mounting cavity 201.

[0035] In this embodiment, by setting the groove 202, the protrusion 212 and the blocking ring 220, when the moving rod 130 extends along the mounting cavity 201, the protrusion 212 slides along the groove 202. When the protrusion 212 slides to the position of the blocking ring 220, the moving rod 130 reaches the farthest end of its extension, thereby preventing the moving rod 130 from sliding out of the mounting cavity 201 and affecting its use.

[0036] When the moving rod 130 moves, the protrusion 212 slides in the groove 202 and limits the moving rod 130, so that the moving rod 130 cannot rotate, thereby preventing the moving rod 130 from rotating and causing the bearing plate 150 to rotate, which is inconvenient to use.

[0037] In actual use, the plug ring 220 is threadedly installed at the opening of the mounting cavity 201, so that the plug ring 220 can be installed and intercept the protrusion 212.

[0038] like Figure 1-3 As shown, in this embodiment, a plurality of positioning holes 211 are uniformly provided on the moving rod 130 along its length direction;

[0039] The positioning assembly includes a drive block 310 disposed in the cavity 301. The drive block 310 is provided with a positioning rod 320 that is inserted into the corresponding positioning hole 211 through the mounting rod 120. The side wall of the cavity 301 is provided with a spring 330 for continuously pushing the drive block 310 to insert one end of the positioning rod 320 into the corresponding positioning hole 211. The cavity 301 is also provided with a moving part for pushing the drive block 310 to move and causing one end of the positioning rod 320 to disengage from the corresponding positioning hole 211.

[0040] In this embodiment, the positioning hole 211, the connecting groove 302, the driving block 310, the positioning rod 320, the spring 330 and the moving part are arranged so that one end of the positioning rod 320 is inserted through the mounting rod 120 into the positioning hole 211 on the positioning rod 320 to achieve the positioning of the positioning rod 320. By inserting the positioning rod 320 into different positioning holes 211, the moving rod 130 is positioned by sliding out different distances.

[0041] Among them, by installing the spring 330, one end of the spring 330 is fixedly installed on the box 140, and the other end abuts against the drive block 310, so that the spring 330 always pushes the drive block 310 to drive the positioning rod 320 to move closer to the positioning hole 211, thereby ensuring that the positioning rod 320 can always remain in the corresponding positioning hole 211.

[0042] In actual use, the moving part is designed to push the drive block 310 to disengage one end of the positioning rod 320 from the positioning hole 211, thereby releasing the positioning of the positioning rod 320. At this time, the positioning rod 320 can slide along the mounting cavity 201 to adjust its length.

[0043] like Figure 1-3 As shown, in this embodiment, a connecting groove 302 for communicating with the cavity 301 is provided on the side wall of the box 140 along its length direction, and a first inclined surface 311 is provided on the end wall of the drive block 310.

[0044] The movable component also includes a movable block 340 that can be slidably disposed in the cavity 301. The movable block 340 has a second inclined surface 341 that cooperates with the first inclined surface 311. The movable block 340 has a lever 350 with one end extending out of the connecting groove 302. The lever 350 drives the movable block 340 to slide along the connecting groove 302, driving the second inclined surface 341 to press the first inclined surface 311, thereby driving the driving block 310 to drive one end of the positioning rod 320 to disengage from the corresponding positioning hole 211.

[0045] In this embodiment, the arrangement of the connecting groove 302, the first inclined surface 311, the moving block 340, the second inclined surface 341, and the lever 350 allows the moving block 340 to slide along the connecting groove 302 by pushing the lever 350. The second inclined surface 341 on the moving block 340 presses against the second inclined surface 341 on the driving block 310, causing the driving block 310 to move upward. This causes the driving block 310 to move the positioning rod 320 out of the corresponding positioning hole 211. At this time, the spring 330 is compressed. When the push on the lever 350 is released, the spring 330 returns to its original position, pushing the driving block 310 to move the positioning rod 320 into the corresponding positioning hole 211. At this time, the first inclined surface 311 on the driving block 310 presses against the second inclined surface 341 on the moving block 340, causing the moving block 340 to move the lever 350 back to its original position along the connecting groove 302. This achieves automatic positioning of the positioning rod 320, making it more convenient to use.

[0046] Among them, a limiting plate 360 ​​is fixedly installed on the side wall of the drive block 310 to abut against the side wall of the cavity 301 and limit the drive block 310. With the installation of the limiting plate 360, when the moving block 340 pushes the drive block 310, the drive block 310 can only drive the positioning rod 320 to approach or disengage from the positioning hole 211, so that the positioning effect of the positioning rod 320 is better.

[0047] In actual use, the opposite sidewalls of the box body 140 extend outward to form a mounting part 370. Each mounting part 370 is provided with a screw 371 that passes through the mounting part 370 and connects to the sidewall of the mounting rod 120. The box body 140 is installed on the sidewall of the mounting rod 120 by means of the screw 371, so that the box body 140 is installed.

[0048] like Figure 1-4 As shown, in this embodiment, a fixing ring 400 is sleeved on the extended end of the moving rod 130, and a rotatable rotating cylinder 410 is also sleeved on the extended end of the moving rod 130. The bearing plate 150 is hinged to the side wall of the rotating cylinder 410, and a limiting ring 420 for limiting the rotating cylinder 410 is threaded at the end of the moving rod 130.

[0049] In this embodiment, by setting up the fixing ring 400, the rotating cylinder 410 and the limiting ring 420, when the rotating cylinder 410 is sleeved on the positioning rod 320, one end wall of the rotating cylinder 410 abuts against the end wall of the fixing ring 400. The limiting ring 420 limits the other end wall of the rotating cylinder 410, so that the rotating cylinder 410 is installed and cannot move along the positioning rod 320. That is, the bearing plate 150 installed on the rotating cylinder 410 is installed.

[0050] Among them, the fixing ring 400 is fixedly installed on the positioning rod 320, and the limiting ring 420 is threadedly installed on the positioning rod 320 to limit the rotation cylinder 410;

[0051] In actual use, the rotating cylinder 410 is clamped by tightening the limiting ring 420. When the limiting ring 420 clamps the rotating cylinder 410, the rotating cylinder 410 cannot rotate, that is, the bearing plate 150 cannot rotate, so that the worker's upper limbs can be stably transported through the bearing plate 150. When the limiting ring 420 is loosened, the rotating cylinder 410 can rotate, that is, it drives the bearing plate 150 to rotate along the positioning rod 320, which makes it convenient for the worker to pick up and put down the goods, and the use effect is good.

[0052] like Figure 1-4 As shown, in this embodiment, a connecting rod 430 is provided on the outer side wall of the rotating cylinder 410, and the bearing plate 150 is rotatably mounted on the connecting rod 430.

[0053] In this embodiment, the connecting rod 430 is provided so that the connecting rod 430 passes through the bearing plate 150 and is threaded onto the rotating cylinder 410, so that the bearing plate 150 can be installed on the rotating cylinder 410.

[0054] In actual use, the support plate 150 has a recessed hole, so that the end of the connecting rod 430 is rotatably installed in the recessed hole through the bearing, thereby realizing the rotation of the support plate 150. At the same time, the upper end of the connecting rod 430 is located in the recessed hole, thus preventing the upper limb from being scratched by the connecting rod 430 when it is placed on the support plate 150.

[0055] Working principle: First, slide the push lever 350 along the connecting groove 302 to release the fixation of the moving rod 130. The moving rod 130 can then extend out of the mounting rod 120 to a suitable position, adjusting the position of the bearing plate 150. Then, release the push lever 350 to fix the moving rod 130. At this time, by loosening the limit ring 420, the bearing plate 150 can rotate the cylinder 410, facilitating the handling of goods. When the limit ring 420 is tightened, the bearing plate 150 cannot rotate, enabling stable handling of goods by the staff. Finally, by adjusting the output torque generated by the mechanical component 110, part of the gravity on the upper limbs can be offset, thereby reducing the load on the upper limbs and alleviating upper limb fatigue.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
