Description

Technical Field

[0001] This utility model relates to an arm-assisting support device, belonging to the technical field of upper limb functional assistive devices. Background Technology

[0002] Upper limb assistive devices are devices designed and used to help restore, enhance, or replace upper limb function. These devices are widely used in many fields such as rehabilitation medicine, assistive technology, and bioengineering, and play a particularly important role in helping people with upper limb dysfunction improve their quality of life.

[0003] Traditional arm support devices mainly consist of a clamp and a support section. The clamp is mainly used to hold the arm to one side of the table, while the support section provides support for the patient's arm. This can relieve the patient's arm support force, reduce the strain on the arm, and facilitate movement.

[0004] However, traditional arm support devices only provide convenient support and cannot provide good assistance to people with severe arm mobility impairments. They cannot meet the needs of different patients, resulting in limited applicability.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing an arm-assisting support device. It can balance the weight of the arm through a spring compensation mechanism, helping the patient's arm to move flexibly. Furthermore, the size of the spring compensation force can be adjusted to meet the needs of different patients, thus expanding its applicability.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] An arm-assisting support device includes a fixed base, a support arm, a weight-reducing support component, and a support arm that are hinged together in sequence. A spring compensation mechanism is installed between the weight-reducing support component and the support arm. An arm fixing accessory is installed at the end of the support arm away from the weight-reducing support component.

[0009] The spring compensation mechanism includes a spring, one end of which is installed inside the end of the support arm, and the other end is installed on the indexing slider. The indexing slider is slidably mounted on the indexing limit plate and is locked in position by the indexing pin.

[0010] Furthermore, the hinge rotation direction of the weight-reducing support and the support arm is perpendicular to the hinge rotation direction of the weight-reducing support and the support arm.

[0011] Furthermore, the supporting swivel arm adopts a multi-section hinged structure.

[0012] Furthermore, the support arm and the weight-reducing support are connected by a hinge shaft, and guide gears are fixedly installed at both ends of the hinge shaft. The guide gears mesh inside the limiting seat, and the limiting seat is fixedly installed inside the weight-reducing support.

[0013] Furthermore, the weight-reducing support is composed of two separate parts, left and right.

[0014] Furthermore, the support arm includes a split-type rotating seat and a carbon fiber tube threaded to the end of the rotating seat.

[0015] Furthermore, the indexing limiting plate has an arc-shaped structure and is fixedly installed inside the weight-reducing support. The indexing limiting plate has multiple evenly distributed indexing holes.

[0016] Furthermore, the indexing pin is installed on the side of the indexing slider, and the indexing pin drives the indexing slider to slide along the indexing limit plate.

[0017] Furthermore, the side of the weight-reducing support is provided with an arc-shaped sliding hole for the indexing pin to slide.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0019] This invention uses a spring compensation mechanism to balance the weight of the arm, helping patients to perform daily activities such as eating, drinking, and retrieving objects independently; the rotation of the support arm and the support rotating arm enables flexible arm movement.

[0020] The indexing pin drives the indexing slider to slide along the indexing limit plate. The indexing pin can be inserted into different indexing holes to adjust the compensating force of the spring, thereby meeting the needs of different patients and improving the applicability.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figures 1-3 As shown in the figure, this utility model provides an arm-assisting support device, including a fixed base 1, a support arm 2, a weight-reducing support 3, and a support arm 4 that are hinged together in sequence. A spring compensation mechanism 6 is installed between the weight-reducing support 3 and the support arm 4. An arm fixing accessory 5 is installed at the end of the support arm 4 away from the weight-reducing support 3.

[0028] The hinge rotation direction of the weight reduction support 3 and the support arm 2 is perpendicular to the hinge rotation direction of the weight reduction support 3 and the support arm 4.

[0029] The support arm 2 adopts a multi-section hinge structure, and the support arm 2 can swing or extend and retract in the horizontal direction.

[0030] The support arm 4 and the weight-reducing support 3 are connected by a hinge shaft. Guide gears 8 are fixedly installed at both ends of the hinge shaft. The guide gears 8 mesh with the limiting seat 9. The limiting seat 9 is fixedly installed inside the weight-reducing support 3.

[0031] The swing angle between the support arm 4 and the weight-reducing support 3 is limited by the cooperation of the guide gear 8 and the limit seat 9.

[0032] The weight-reducing support 3 is composed of two separate parts, left and right.

[0033] The support arm 4 includes a split rotating seat and a carbon fiber tube threaded to the end of the rotating seat.

[0034] The spring compensation mechanism 6 includes a spring 61. One end of the spring 61 is installed inside the end of the support arm 4, and the other end of the spring 61 is installed on the indexing slider 64. The indexing slider 64 is slidably disposed on the indexing limit plate 62 and is locked in position by the indexing pin 65.

[0035] The indexing limiting plate 62 has an arc-shaped structure and is fixedly installed inside the weight reduction support 3. The indexing limiting plate 62 has a plurality of evenly distributed indexing holes 63.

[0036] The indexing pin 65 is installed on the side of the indexing slider 64. The indexing pin 65 drives the indexing slider 64 to slide along the indexing limit plate 62. The indexing pin 65 adjusts the compensating force of the spring 61 by inserting into different indexing holes 63.

[0037] The side of the weight-reducing support 3 is provided with an arc-shaped sliding hole 7 for the indexing pin 65 to slide.

[0038] The specific working principle of this utility model is as follows:

[0039] This invention connects to the arm via an arm-fixing accessory. During operation, a spring compensation mechanism balances the arm's weight, assisting patients in performing daily activities such as eating, drinking, and retrieving objects independently. The arm's flexible movement is achieved through the rotation of the support arm and the support rotating arm.

[0040] The indexing pin drives the indexing slider to slide along the indexing limit plate. The indexing pin can be inserted into different indexing holes to adjust the compensating force of the spring, thereby meeting the needs of different patients and improving the applicability.
