Abstract
Description

[0001] This invention relates to the field of auxiliary support equipment technology, and in particular to an arm auxiliary support equipment. Background Technology
[0002] In scenarios where users work with their arms raised for extended periods, fatigue and even injury can easily occur. To address this issue, arm support devices are currently used to support the user's arms and reduce the intensity of labor.
[0003] However, existing arm support devices mainly consist of a support rod, a lever, and an elastic band. The lever is hinged to the support rod, with one end connected to the arm and the other end connected to the elastic band. Under the elastic force of the elastic band, a downward pulling force can be applied to the lever, causing the end of the lever connected to the arm to rotate upward, thus providing an upward assist effect to the user's arm. However, the lever in the above structure mainly relies on the tension of the elastic band, and the tension of the lever gradually decreases when the user's arm is raised from horizontal to overhead. Therefore, the support stability of the lever is poor, which in turn affects the user's stable control of the object being held during operation.
[0004] Therefore, how to improve the support effect of arm-assisted support devices on the arm is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0049] Please refer to Figures 1 to 7 The arm-assisted support device provided in this embodiment of the invention includes: a support member 10, a first movable member 20, a second movable member 30, a third movable member 40, a first connecting part 50, and an energy storage part 60. The support member 10, the first movable member 20, the second movable member 30, and the third movable member 40 can all be selected as rods. The arm-assisted support device also includes a wearable device, which includes a back strap part 100, a waist belt part 200, and an arm strap part 300. The upper end of the support member 10 is connected to the shoulder strap 100, and the lower end of the support member 10 is connected to the waist belt 200. One end of the first movable member 20 is movably connected to the support member 10, for example, one end of the first movable member 20 is hinged to the upper end of the support member 10 via a first hinge shaft 01. The first movable member 20 is used to connect to the arm, for example, one end of the first movable member 20 away from the support member 10 is connected to the armband 300, and the armband 300 is wrapped around the user's upper arm. One end of the second movable member 30 is movably connected to the first movable member 20, and the other end is movably connected to the third movable member 40. For example, the upper end of the second movable member 30 is hinged to the rod of the first movable member 20 via a second hinge shaft 02, and the lower end of the second movable member 30 is hinged to the third hinge shaft 40. The connecting shaft 03 is hinged to the third movable member 40; one end of the third movable member 40 is movably connected to the support member 10, for example, the third movable member 40 is hinged to the support member 10 via the fourth hinge shaft 04; the first connecting part 50 is provided on the second movable member 30 or the third movable member 40, for example, the first connecting part 50 can be provided on the second movable member 30 at a position away from the first movable member 20, or the first connecting part 50 can be provided on the third movable member 40; the first end of the energy storage part 60 is connected to the support member 10, for example, the first end of the energy storage part 60 is connected to the support member 10 at a position near the upper end, and the second end of the energy storage part 60 is connected to the first connecting part 50, that is, the connection position of the second end of the energy storage part 60 can be located on the second movable member 30 or the third movable member 40. After the user wears the above-mentioned arm assistive support device, when the arm is in a horizontal position, the positional relationship of each component is as follows. Figure 1 As shown; when the arm is in the lowered position, the positional relationship of each component is as follows: Figure 2As shown, when the arm is in the raised position, the positional relationship of each component is as follows: Figure 3 As shown, the energy storage unit 60 is always taut regardless of the arm's position. The energy storage unit 60 applies an upward pulling force to the first connecting part 50. For example, when the user's upper arm is in a horizontal position, when the upper arm is subjected to downward pressure, the first movable member 20 will generate a downward rotational torque relative to the support member 10. At this time, the second movable member 30 will tend to move downward, thereby generating a downward rotational torque on the third movable member 40. However, because the first connecting part 50, under the pulling force of the energy storage unit 60, applies an upward pulling force to the second movable member 30 and the third movable member 40, the second movable member 30 effectively supports the first movable member 20, thereby improving the support effect on the arm.
[0050] In some embodiments, such as Figure 4 and Figure 5 As shown, the first connecting part 50 is movably connected to the second movable member 30 or the third movable member 40. The second movable member 30 or the third movable member 40 is provided with an adjusting member. For example, when the first connecting part 50 is movably connected to the second movable member 30, the second movable member 30 is provided with a corresponding adjusting member; when the first connecting part 50 is movably connected to the third movable member 40, the third movable member 40 is provided with a corresponding adjusting member. The position of the first connecting part 50 can be adjusted via the adjusting member to change the distance between the hinge axis of the first connecting part 50 and the third movable member 40 and the support member 10. For example… Figure 1As shown, the first connecting part 50 is movably connected to the third movable member 40. The third movable member 40 and the support member 10 are relatively movably connected through the fourth hinge shaft 04. When the first connecting part 50 moves to the left, the distance between the first connecting part 50 and the fourth hinge shaft 04 can be increased, thereby increasing the pulling force of the energy storage part 60 on the first connecting part 50. When the first connecting part 50 moves to the right, the distance between the first connecting part 50 and the fourth hinge shaft 04 can be decreased, thereby decreasing the pulling force of the energy storage part 60 on the first connecting part 50. In practical use, when it is necessary to lift a heavier object, the distance between the first connecting part 50 and the fourth hinge shaft 04 can be increased. Conversely, when the object is lighter, the distance between the first connecting part 50 and the fourth hinge shaft 04 can be decreased. It should be noted that the adjustment component can be automatically or manually adjusted. For example, the first connecting part 50 can be moved by a linear motor. Furthermore, a pressure sensor can be installed on the first movable component 20. The pressure sensor can detect and send the detected information to the controller. The controller then determines whether the pressure exceeds the first preset pressure value. If so, the first connecting part 50 is moved away from the fourth hinge axis 04 by the linear motor to increase the distance between the two. If the pressure is lower than the second preset pressure value, the first connecting part 50 is moved towards the first hinge axis 01 by the linear motor to decrease the distance between the two. The first preset pressure value is greater than the second preset pressure value.
[0051] In some embodiments, such as Figure 5 As shown, the adjusting component includes a threaded adjusting component 41. A groove is provided on the third movable member 40. The first connecting part 50 is slidably connected to the groove via a slider. The threaded adjusting component 41 is threadedly connected to the slider. For example... Figure 1 As shown, a groove is provided on one side of the third movable member 40. The extension direction of the groove is parallel to the length direction of the third movable member 40. The slider is placed in the groove. The slider is constrained by the groove and can only move without rotating. One end of the first connecting part 50 is connected to the slider, and the other end is located outside the groove. The threaded adjusting part 41 passes through the third movable member 40 from the end away from the supporting member 10 and is threadedly connected to the slider. By turning the threaded adjusting part 41, the movement of the slider can be adjusted, thereby adjusting the distance between the first connecting part 50 and the fourth hinge shaft 04.
[0052] In some embodiments, such as Figure 5As shown, the energy storage unit 60 includes an elastic part 61, a first pull rope 62, and a second pull rope 63. The elastic part 61 can be a rubber band or a spring, and the first pull rope 62 and the second pull rope 63 can be steel wire ropes. One end of the first pull rope 62 is connected to one end of the elastic part 61, and the other end of the first pull rope 62 is connected to or wound around the first connecting part 50 to connect with the support member 10 or the third movable member 40. The first connecting part 50 can be a pulley, and the first pull rope 62 is wound around the pulley, that is, the pulley can engage the first pull rope. 62 serves as a reversing element. For ease of connection, the first pull rope 62 can be connected to the third movable member 40 and the fourth hinge shaft 04 of the support member 10. Furthermore, when the third movable member 40 is in a horizontal state, the height of the first connecting part 50 is lower than the position of the fourth hinge shaft 04. One end of the second pull rope 63 is connected to the other end of the elastic part 61, and the other end of the second pull rope 63 can be directly fixed to the support member 10, or fixed to the first hinge shaft 01 of the first movable member 20 and the support member 10. It should be noted that the above embodiment is described using the elastic part 61 as an example. In addition, the energy storage part 60 can be selected as a pull rope, one end of which is connected to a winch. The winch can be installed on the support member 10, and the length of the pull rope can be controlled by the winch, thereby applying tension to the first connecting part 50 through the pull rope. The winch can be used in conjunction with the pressure sensor and controller mentioned above.
[0053] In some embodiments, such as Figure 6 As shown, the arm-assisted support device also includes a second connecting part 70, which is disposed on the support member 10 or the first movable member 20. For example, the second connecting part 70 can be disposed on the upper end of the support member 10, or the second connecting part 70 can be disposed on the first movable member 20. That is, the second connecting part 70 can be located on the support member 10 or the first movable member 20. The first end of the energy storage part 60 is wound around the second connecting part 70 to connect with the first movable member 20. The end of the second pull rope 63 away from the elastic part 61 is wound around the second connecting part 70 to connect with the first movable member 20. For example, the second connecting part 70 can be connected to the first hinge shaft 01, and the end of the second pull rope 63 away from the elastic part 61 is connected to the second hinge shaft 02 of the first movable member 20 and the second movable member 30. The energy storage unit 60 can apply a pulling force to the first movable member 20. For example, when the user's upper arm is hanging down, the energy storage unit 60 can apply an upward pulling force to the first movable member 20 when the user's upper arm is raised, thereby providing assistance. When the user's upper arm is in a horizontal position, the energy storage unit 60 is Z-shaped under the action of the first connecting part 50 and the second connecting part 70.
[0054] In some embodiments, the first connecting portion 50 and the second connecting portion 70 are preferably pulleys. Pulleys can reduce friction on the energy storage unit 60, thereby improving its service life. It should be noted that pulleys are only one preferred option; cylinders can also be used as the first connecting portion 50 and the second connecting portion 70. Furthermore, to prevent the first pull rope 62 and the second pull rope 63 from detaching, grooves for accommodating the pull ropes can be provided on the outer periphery of the cylinder.
[0055] In some embodiments, the first movable member 20 is an axially extendable telescopic rod. For example, the telescopic rod includes multiple segments of rods that are sequentially connected. The telescopic rod can adapt to the needs of different users; for example, when the user's arm is long, the telescopic rod can be extended, and when the user's arm is short, the telescopic rod can be shortened. Figure 1 and Figure 5 As shown, the first movable component 20 includes a base rod 21 and an arm connecting rod 22. The base rod 21 has a hollow structure inside. The arm connecting rod 22 passes through the base rod 21, and the end of the arm connecting rod 22 extends out of the base rod 21. The side wall of the base rod 21 is provided with a plurality of connecting holes distributed along its axial direction. A spring pin can be provided on the side wall of the arm connecting rod 22. The spring pin can be selectively engaged in one of the connecting holes to achieve axial fixation of the arm connecting rod 22 relative to the base rod 21.
[0056] In some embodiments, the first movable member 20 is parallel to the third movable member 40, and the second movable member 30 is parallel to the support member 10, wherein the support member 10, the first hinge shaft 01, the first movable member 20, the second hinge shaft 02, the second movable member 30, the third hinge shaft 03, the third movable member 40, and the fourth hinge shaft 04 form a deformable parallelogram mechanism. One end of the first movable member 20, away from the support member 10, extends forward from the second movable member 30 to facilitate connection with an arm.
[0057] In some embodiments, such as Figure 1 and Figure 5 As shown, a support portion is provided at one end of the support member 10 away from the first movable member 20. That is, the support portion extends downward relative to the horizontal position of the third movable member 40. For example, the support portion is connected to the waist belt portion 200 so that the user's waist supports the support member 10. The support member 10 can be a square tube or a round tube, and its weight can be reduced by using a hollow structure.
[0058] In some embodiments, the support includes a support rod 12 and a ball joint 11. One end of the support rod 12 is movably connected to the support member 10 along its length. For example, multiple axially distributed adjustment holes can be provided on the support rod 12, and a snap-fit member 94 is provided on the support member 10. When the support rod 12 moves vertically so that one of the adjustment holes corresponds to and snaps into the snap-fit member 94, the support rod 12 can be fixed in the height direction. Alternatively, multiple axially distributed connection holes can be provided on the side wall of the support member 10, and the support rod 12 can be fixed by passing a pin or screw through the connection holes on the support member 10. The ball joint 11 is located at the other end of the support rod 12. Correspondingly, such as Figure 1 As shown, the waist belt 200 is provided with a hinge support 201. The support member 10 can move relative to the hinge support 201 through the ball joint 11, thereby facilitating the user's body movements.
[0059] In some embodiments, such as Figure 4 As shown, the arm support device has an energy storage unit 60 on both its inner and outer sides. The inner side refers to the side closer to the user's body, and the outer side refers to the side away from the user's body. The two energy storage units 60 improve the support stability of the arm support device and provide safety redundancy; for example, if one energy storage unit 60 breaks, the other energy storage unit 60 can still be used. To prevent injury to the user from pinching due to relative changes in the position of the arms, a protective shell 80 can be installed on both the inner and outer sides of the arm support device. Furthermore, during use, it can support one of the user's arms, or two sets can be installed to support both arms separately.
[0060] In some embodiments, such as Figure 8 and Figure 9 As shown, the support member 10 includes a housing 90, within which a chamber is provided for accommodating the energy storage unit 60 and the second movable member 30. The housing serves to support the first movable member 20 and the third movable member 40. Specifically, the housing includes a first shell 91 and a second shell 92, with one side of the first shell 91 and the second shell 92 fixedly connected. Figure 8As shown, the right sides of the first housing 91 and the second housing 92 are connected by fasteners. A gap is left between the opposing left sides of the first housing 91 and the second housing 92 to form the aforementioned chamber. The upper, left, and lower sides of the first housing 91 and the second housing 92 are not sealed to facilitate the movement of the first movable member 20, the second movable member 30, and the third movable member 40. Further, a through hole can be provided on the first housing 91. A snap-fit member 94 is located inside the housing and protrudes from the through hole. The support rod 12 has multiple axially distributed adjustment holes. A slide rail 93 is provided inside the housing 90. The upper part of the support rod 12 is slidably connected to the slide rail 93 to achieve height adjustment of the support rod 12. The snap-fit member 94 has a snap-fit protrusion that can selectively snap into one of the adjustment holes to fix the support rod 12 in the height direction. In addition, to facilitate the connection of the first movable member 20, a connector 95 can be provided at the upper end of the housing 90. The connector 95 can be an L-shaped member. One end of the connector 95 is fixed inside the housing 90, and the other end protrudes inside the housing 90 so as to be hinged to one end of the first movable member 20.
