[0034] like Figure 1 As shown, the adjustment device 10 in one embodiment includes a base 100, a first telescopic component 200, a second telescopic component 300 and an adjustment component 400. The base 100 is used to be installed on the waist support structure of the power-assisted exoskeleton; the first telescopic component 200 extends from one end portion of the base 100 into the base 100; the second telescopic component 300 extends from the other end portion of the base 100 into the base 100; the adjustment component 400 is linked with the first telescopic component 200 and the second telescopic component 300, and the adjustment component 400 can drive the first telescopic component 200 and the second telescopic component 300 to move synchronously in opposite directions relative to the base 100, so that the lengths of the first telescopic component 200 and the second telescopic component 300 extending outside the base 100 are synchronously adjustable.

[0035] The above-mentioned adjustment device 10, whose base 100 is used to be installed on the waist support structure of the power-assisted exoskeleton, is because the adjustment component 400 can drive the first telescopic component 200 and the second telescopic component 300 to move synchronously in opposite directions relative to the base 100, so that the lengths of the first telescopic component 200 and the second telescopic component 300 extending outside the base 100 can be adjusted synchronously, thereby realizing symmetrical adjustment of the dimensions at both ends of the base 100, and further enabling the dimensions of the waist support mechanism of the power-assisted exoskeleton to be adjusted according to the waist circumference of the wearer to adapt to the actual use needs of wearers with different waist circumferences, and ensuring that the wearer is symmetrically centered relative to the waist support structure of the power-assisted exoskeleton, thereby improving the performance of the waist support structure of the power-assisted exoskeleton.

[0036] like Figure 2 and Figure 3As shown, further, the adjustment component 400 includes a first rack 410, a second rack 420 and a rotating shaft 430. The first rack 410 is arranged in the base 100 and connected to one end of the first telescopic component 200; the second rack 420 is arranged in the base 100 and connected to one end of the second telescopic component 300; one end of the rotating shaft 430 extends from one side of the base 100 into the base 100, and a gear 440 is arranged at one end of the rotating shaft 430, and both sides of the gear 440 are respectively meshed with the first rack 410 and the second rack 420, and the rotating shaft 430 can rotate around its own axis relative to the base 100 to pass The meshing transmission between the gear 440 and the first rack 410 and the second rack 420 drives the first rack 410 and the second rack 420 to move synchronously in opposite directions within the base 100, thereby driving the first telescopic assembly 200 and the second telescopic assembly 300 to move synchronously in opposite directions relative to the base 100, thereby making the lengths of the first telescopic assembly 200 and the second telescopic assembly 300 extending outside the base 100 synchronously adjustable, achieving symmetrical adjustment of the dimensions at both ends of the base 100, and thereby enabling the dimensions of the waist support mechanism of the power-assisted exoskeleton to be adjusted according to the waist circumference of the wearer to meet the actual usage needs of wearers with different waist circumferences.

[0037] like Figure 4 As shown, in one embodiment, the first rack 410 includes an auxiliary portion 412 and a rack portion 414, the auxiliary portion 412 is connected to one end of the first telescopic assembly 200, and the rack portion 414 is connected to a side of the auxiliary portion 412 away from the first telescopic assembly 200, and meshes with the gear 440. By driving the rotating shaft 430 to rotate around its own axial direction, the first rack 410 can be driven to move toward or away from the end of the base 100 through which the first telescopic assembly 200 is inserted through the meshing transmission of the gear 440 and the rack portion 414 of the first rack 410, thereby driving the first telescopic assembly 200 to move relative to the end of the base 100, so as to achieve the length adjustment of the first telescopic assembly 200 extending outside the base 100.

[0038] In this embodiment, the auxiliary portion 412 and the rack portion 414 are integrally formed. Further, in this embodiment, the structure of the second rack 420 is the same as that of the first rack 410, and will not be described again.

[0039] like Figure 5As shown, in one embodiment, the adjustment assembly 400 further includes a bearing 450, the bearing 450 is disposed in the base 100, and the rotating shaft 430 is rotatably disposed in the base 100 through the bearing 450. Further, the bearing 450 includes a plurality of bearings, and the plurality of bearings 450 are spaced relative to the rotating shaft 430 along the axial direction of the rotating shaft 430. In this embodiment, the bearing 450 includes two bearings, and the two bearings 450 are spaced relative to the rotating shaft 430 along the axial direction of the rotating shaft 430. It can be understood that in other embodiments, the number of bearings 450 can be one or more than three, and the specific arrangement method can be reasonably selected according to actual conditions.

[0040] Furthermore, the adjustment assembly 400 further includes a knob 460 for conveniently applying an external force to rotate the shaft 430 around its own axial direction relative to the base 100 . The knob 460 is sleeved on one end of the shaft 430 away from the gear 440 .

[0041] like Figure 6 As shown, further, a through hole 110 is provided on one side of the base 100, and the knob 460 passes through the through hole 110 and extends into the base 100, and a boss 462 is provided on the side of the knob 460 facing the gear 440. A support frame 500 is also provided in the base 100, and a plurality of sockets 520 are provided on the support frame 500. The plurality of sockets 520 are arranged at axial intervals around the rotating shaft 430. The knob 460 can move axially along the rotating shaft 430 relative to the rotating shaft 430 and the base 100 to drive the boss 462 to move toward or away from the socket 520, so that the boss 462 is matched with or separated from the socket 520, thereby locking the axial rotation of the knob 460 around the rotating shaft 430 or releasing the lock on the axial rotation of the knob 460 around the rotating shaft 430.

[0042] Specifically, initially, the boss 462 on the knob 460 is matched with a certain socket 520 on the support frame 500, so that the knob 460 is locked and cannot be rotated around the axial direction of the shaft 430. When the size of the waist support mechanism of the power-assisted exoskeleton needs to be adjusted, the knob 460 is pulled out along the axial direction of the shaft 430 and toward the outside of the base 100 to drive the boss 462 to move along the axial direction of the shaft 430 and away from the currently matched socket 520 on the support frame 500, so that the boss 462 is separated from the currently matched socket 520 on the support frame 500, thereby releasing the lock on the axial rotation of the knob 460 around the rotating shaft 430. At this time, the rotating shaft 430 can be driven to rotate by rotating the knob 460, and then the first telescopic component 200 and the second telescopic component 300 are driven to move synchronously in the opposite direction relative to the base 100 through the meshing transmission of the gear 440 and the first rack 410 and the second rack 420, thereby realizing the adjustment of the size of the lumbar support mechanism of the power-assisted exoskeleton.

[0043] After the size of the lumbar support mechanism of the above-mentioned power-assisted exoskeleton is adjusted, the knob 460 is pressed along the axial direction of the rotating shaft 430 and toward the inside of the base 100 to drive the boss 462 to move along the axial direction of the rotating shaft 430 and toward another socket 520 on the support frame 500, so that the boss 462 on the knob 460 cooperates with another socket 520 on the support frame 500, thereby realizing the re-locking of the axial rotation of the knob 460 around the rotating shaft 430, so as to improve the safety of the use of the adjustment device 10 and ensure that the size of the lumbar support mechanism of the power-assisted exoskeleton will not change after being adjusted.

[0044] It should be pointed out that in this embodiment, a bearing mounting hole 540 is provided on the support frame 500, and a plurality of sockets 520 are arranged at intervals around the bearing mounting hole 540, and one of the two bearings 450 that is relatively close to the knob 460 is installed in the bearing mounting hole 540 of the support frame 500.

[0045] like Figure 6 As shown, further, a through slot 120 is provided on one side of the base 100, and the through slot 120 extends along the telescopic direction of the first telescopic component 200. A slot 464 is provided on the circumference of the knob 460. The above-mentioned adjustment device 10 also includes a push-up component 600, and the push-up component 600 includes a push-up member 620 and an elastic member 640. The push-up member 620 passes through the through slot 120 and extends into the base 100. The elastic member 640 elastically abuts against one end of the push-up member 620 away from the slot 464. The push-up member 620 can move relative to the through slot 120 in a direction close to or away from the slot 464 to cooperate with or separate from the slot 464, thereby locking the knob 460 along the axial movement of the rotating shaft 430 or releasing the lock on the axial movement of the knob 460 along the rotating shaft 430. The elastic member 640 is used to provide a restoring force to the push-up member 620 to move in a direction close to the slot 464.

[0046] Initially, the push piece 620 cooperates with the slot 464 on the circumference of the knob 460, and the boss 462 on the knob 460 cooperates with a certain socket 520 on the support frame 500, so that the knob 460 is locked and cannot move along the axial direction of the shaft 430 or rotate around the axial direction of the shaft 430. When it is necessary to rotate the knob 460 to adjust the size of the waist support mechanism of the power-assisted exoskeleton, the push piece 620 is first driven by external force relative to the through slot 120. Move in a direction away from the slot 464 on the circumference of the knob 460 to separate from the slot 464 on the circumference of the knob 460, thereby releasing the lock on the axial movement of the knob 460 along the shaft 430. At this time, the knob 460 can be driven to move along the axial direction of the shaft 430 to release the lock on the subsequent axial rotation of the knob 460 around the shaft 430, and then the size of the lumbar support mechanism of the power-assisted exoskeleton can be adjusted by rotating the knob 460;

[0047] When the size of the lumbar support mechanism of the above-mentioned power-assisted exoskeleton is adjusted and the axial rotation of the knob 460 around the rotating shaft 430 is re-locked, the external force acting on the push-up member 620 is released at this time, and the push-up member 620 is automatically reset relative to the through groove 120 in the direction of the circumferential groove 464 of the knob 460 under the action of the restoring force provided by the elastic member 640. The push-up member 620 cooperates with the circumferential groove 464 of the knob 460 again and re-locks the axial movement of the knob 460 along the rotating shaft 430, thereby ensuring that the boss 462 on the knob 460 will not be accidentally separated from the other currently matched socket 520 on the support frame 500, so as to further improve the safety of the use of the adjustment device 10 and ensure that the size of the lumbar support mechanism of the power-assisted exoskeleton will not change after it is adjusted.

[0048] In one embodiment, the abutting assembly 600 further includes a shifting member 660 for conveniently applying an external force to move the abutting member 620 relative to the through slot 120 . The shifting member 660 is disposed at one end of the abutting member 620 exposed from the base 100 .

[0049] like Figure 5 and Figure 6 As shown, further, a step 466 is formed in the knob 460, and the adjustment assembly 400 also includes a limit member 470, which is sleeved in the knob 460 and fixed to the end of the shaft 430 away from the gear 440. The limit member 470 can abut against the step 466 to limit the axial movement of the knob 460 relative to the shaft 430 and the base 100 along the shaft 430, thereby preventing the knob 460 from accidentally falling off relative to the shaft 430.

[0050] like Figure 3 and Figure 4 As shown, further, the first telescopic component 200 includes a slider 210, a slide rail 220 and a fixing member 230, the slider 210 is fixed in the base 100; the slide rail 220 extends from one end portion of the base 100 into the base 100, and slides with the slider 210; the adjustment component 400 is linked with the slide rail 220; the fixing member 230 is arranged at one end of the slide rail 220 exposed from the base 100, and the adjustment component 400 can drive the slide rail 220 to reciprocate relative to the slider 210 along the extension direction of the slide rail 220, thereby driving the fixing member 230 to move toward or away from the end of the base 100 for the slide rail 220 to pass through, thereby realizing the size adjustment of the end of the base 100 for the slide rail 220 to pass through.

[0051] Specifically, the first rack 410 of the adjustment component 400 is connected to the end of the slide rail 220 away from the fixing member 230. More specifically, the fixing portion 412 of the first rack 410 is connected to the end of the slide rail 220 away from the fixing member 230. By driving the rotating shaft 430 to rotate around its own axial direction, the first rack 410 can be driven by the meshing transmission of the gear 440 and the first rack 410 to move toward or away from the end of the base 100 through which the slide rail 220 passes, thereby driving the slide rail 220 to reciprocate relative to the slider 210 along the extension direction of the slide rail 220, and then driving the fixing member 230 to move toward or away from the end of the base 100 through which the slide rail 220 passes, thereby realizing the size adjustment of the end of the base 100 through which the slide rail 220 passes.

[0052] like Figure 3 and Figure 4 As shown, in the present embodiment, the slider 210 and the slide rail 220 are arranged in pairs, and the two sliders 210 are arranged at intervals in the base 100. Specifically, the two sliders 210 are respectively arranged on the two opposite inner walls of the base 100, the two slide rails 220 correspond to the two sliders 210 one by one, the fixing member 230 is connected to one end of the two slide rails 220 exposed from the base 100, and the first rack 410 of the adjustment component 400 is connected to one end of the two slide rails 220 away from the fixing member 230. More specifically, the fixing portion 412 of the first rack 410 is connected to one end of the two slide rails 220 away from the fixing member 230.

[0053] Furthermore, a ball bearing is provided inside the slider 210, and the ball bearing is used to reduce the friction between the slider 210 and the slide rail 220, so that the size adjustment of the waist support mechanism of the power-assisted exoskeleton is more labor-saving, the user experience is improved, and the noise is reduced. It should be pointed out that in this embodiment, the structure of the second telescopic assembly 300 is the same as that of the first telescopic assembly 200, and will not be elaborated here.

[0054] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
