[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] The present application is a foldable and storable wearable device, which comprises a leg rod assembly, a main body structure rod, and a rotating shaft mechanism 7. The two ends of the main body structure rod are respectively connected to at least one leg rod assembly. The main body structure rod is connected by the rotating shaft mechanism 7 inside, and the rotating shaft mechanism 7 is used to realize the folding and storage of the wearable device.

[0034] In combination with Figure 2The main structural rod includes a rear waist rod 3 and side waist rods 4; at least one side waist rod 4 is connected to each end of the rear waist rod 3, and the two are connected by at least one of the rotating shaft mechanisms 7. The side waist rods 4 connected to the two ends of the rear waist rod 3 are mirror images, but the two mirror images of the side waist rods 4 are not fundamentally different in structure, so they are both referred to as side waist rods 4; the two ends of the rear waist rod 3 are connected to the side waist rods 4 by hinges in the form of hinges; the rear waist rod 3 and the rotating shaft female hinge 703 can be connected by shaft hole fitting / welding / riveting.

[0035] The rotating mechanism 7 includes a female hinge 703 and a male hinge 704. The male hinge 704 includes a hinge portion and a main body portion, and the female hinge 703 includes a hinge portion and a main body portion. The upper part of the hinge portion of the male hinge 704 is provided with a spline groove, and the lower part is a cylindrical through hole. The hinge portion of the female hinge 703 and the hinge portion of the male hinge 704 cooperate with each other to realize the folding and storage of the wearable device. The main body portion of the female hinge 703 is connected to the rear waist bar 3, and its other side is connected to the main body portion of the male hinge 704. The other side of the main body portion of the male hinge 704 is connected to the side waist bar 4.

[0036] Combination Figure 4 and Figure 5 The rotating shaft mechanism 7 further includes a splined shaft 701, a limiting sleeve 702, rubber plugs 705, and a spring 706. The splined shaft 701 has a through hole at its top for connecting to a traction rope, and its bottom is connected to the bottom of the spline groove of the male hinge 704. The limiting sleeve 702 is placed in the bottom hole of the female hinge 703 and contacts the spring 706. The spring 706 is installed in the lower section of the hinge portion of the female hinge 703 to provide locking force for locking the splined shaft 701. The rubber plugs 705 are provided at both ends of the hinge portion of the male hinge 704 to guide the splined shaft 701. The hinge portion of the male hinge 704 and the rubber plugs 705 at both ends fit into the middle empty section of the hinge portion of the female hinge 703.

[0037] The splined shaft 701 has a threaded hole at its end, and an external screw is tightened on the outside of the limiting sleeve 702 to axially fix the male hinge 704 and surrounding parts on the female hinge 703.

[0038] The rubber sleeve 705 includes a first rubber sleeve for supporting the upper part of the hinge portion of the male hinge 704 and the female hinge 703 of the rotating shaft, so as to prevent rigid friction caused by their rotation; it also includes a second rubber sleeve for supporting the lower part of the hinge portion of the male hinge 704 and the female hinge 703 of the rotating shaft, so as to prevent rigid friction caused by their rotation.

[0039] Combination Figure 3 The side waist rod 4 has a motor bracket inside, on which a drive motor 6 is mounted. The drive motor 6 is fixedly connected to the motor bracket by screws.

The drive circuit extends through the motor bracket and is connected to the rotor surface of the drive motor 6 for drive control. The side waist rod 4 has a motor housing for decoration and fixation. The side waist rod 4 has a contoured waist support 5, which is connected to the motor bracket by screws. The contoured waist support 5 conforms to the curve of the human waist, improves wearing comfort, and effectively prevents the wearable device from shifting.

[0040] The drive motor 6 is used to drive the leg assembly to move; the rear waist bar 3 is equipped with a power supply and controller 8, which are connected through the binding screw holes on the rear waist bar 3. The power supply and controller 8 is used to supply power to the machine and send control signals; the power lines and signal lines of the power supply and controller 8 are connected to the drive motor 6 through the through holes of the main body of the female hinge 703 and the male hinge 704.

[0041] Combination Figure 1 At least one leg rod assembly is mirror-mounted at each end of the main structural rod. The leg rod assembly includes a leg rod 1 and a protective gear 2. The mirror-mounted leg rod 1 and protective gear 2 are structurally identical and are therefore referred to as leg rod 1 and protective gear 2. One end of the leg rod 1 is positioned to the end face of the drive motor 6 in the side waist rod 4 through three pin holes and connected by six screws. The other end is connected to the protective gear 2, which can be connected by locking screws / pins / riveting.

[0042] Combination Figure 6 The leg rod 1 includes a thigh rod 101, a glass bead plunger rod 102, and a motor output rod 103;

[0043] The thigh rod 101 and the glass ball plunger rod 102 are engaged in a stepped fit.

The other end of the thigh rod 101 is connected to the protective gear 2. The glass ball plunger rod 102 is connected to the shaft hole of the motor output rod 103, providing the thigh rod 101 with an outward extension freedom. The motor output rod 103 is fixedly connected to the drive motor 6 by a locking screw.

[0044] The present invention provides a method for operating a foldable and retractable wearable device, including a folding and retracting method and an unfolding method.

[0045] The folding and storage method involves pulling out the spline shaft 701 axially until the limiting sleeve 702 abuts against the bottom of the cylindrical hole at the lower end of the female hinge 703. The side waist rod 4 is then rotated 90° to loosen the spline shaft 701, allowing its spline portion to fall into the spline hole of the female hinge 703 and the spline hole of the male hinge 704, thus locking the side waist rod 4 and achieving folding and storage. Simultaneously, when storing the leg rod 1, the thigh rod 101 is pulled out from the bottom groove of the glass bead plunger rod 102, completing the disassembly of the thigh rod 101 and separating it from the main body of the folded hip joint wearable device, thus completing the overall folding and storage.

[0046] The unfolding method involves pulling the splined shaft 701 axially until the limiting sleeve 702 abuts against the bottom end of the cylindrical shaft hole of the female hinge 703. The side waist rod 4 is then rotated 90° in the opposite direction to loosen the splined shaft 701, allowing it to fall into the spline hole of the female hinge 703 and the spline hole of the male hinge 704, thus locking the side waist rod 4 and enabling its unfolding. Simultaneously, as the leg rod 1 unfolds, the thigh rod 101 is inserted into the bottom groove of the glass bead plunger rod 102, completing the assembly of the thigh rod 101. This then combines with the unfolded main structure rod and the rotating shaft mechanism 7, completing the unfolding of the device.

[0047] Completed hip joint wearable device such as Figure 2 As shown, the storage space required for the final folded storage state is less than 40cm×20cm×20cm.

[0048] Example

[0049] (1) The spline shaft 701 in the rotating shaft mechanism 7 can be a non-cross spline, and different shapes of splines can be designed to make the side waist bar 4 fold at different angles;

[0050] (2) When the limiting sleeve 702 is pressed upward, it can be used in the form of a button. When the button is pressed, the rotating shaft is locked. When the button is pressed again, the button pops up, and the rotating shaft mechanism 7 becomes rotatable.

[0051] (3) When the spline shaft 701 is pulled upward, a spring can be used. The spring 706 provides a tendency force in both the extended and folded states of the shaft 7. When it reaches the end of the extended / folded state, it is held by the structural member to counteract the tendency force provided by the spring 706, so that it moves within a controllable range.

[0052] (4) The disassembly and assembly method of the thigh rod 101 and the glass bead plunger rod 102 can be changed to a buckle or a button. The button mechanism is realized by a spring snap-fit ​​limiting structure.
