Technical Field

[0001] This utility model relates to a writing exoskeleton assistive device, belonging to the technical field of assistive writing devices. Background Technology

[0002] For young children and adolescents, this is a crucial period for physical development and the formation of good writing habits. However, due to a lack of guidance on proper writing posture, coupled with heavy academic pressure and prolonged periods of writing at a desk, many young children and adolescents suffer from problems such as hunching over, excessive forward head tilting, improper arm positioning, and incorrect pen grip. Prolonged poor writing posture not only affects the development of the spine and vision, but also leads to slow writing speed, messy handwriting, and even aversion to writing. Most existing writing aids on the market are structurally simple. For example, ordinary pen grips only assist in holding the pen and cannot provide overall arm support and guidance. While some desktop correctors can correct posture to some extent, their effect on proper arm and hand posture during writing is limited. Furthermore, some rehabilitation training devices, although providing some strength assistance, lack precise adaptation to writing movements, and are bulky and complex to operate, making them inconvenient for young children and adolescents in their daily writing. Therefore, there is an urgent need to design a writing exoskeleton that can effectively support, guide, and assist the arm, while also being comfortable, flexible, and scientifically designed to help young children and adolescents develop correct writing posture and meet the writing needs of different groups.

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.

[0013] Please see Figure 1-4 As shown, a writing exoskeleton assistive device includes a desktop mounting component 100, an arm support 110 slidably mounted on the desktop, a first strap 111-a and a second strap 111-b on the arm support 110, and a contoured groove 112 on the upper surface of the arm support 110, the contoured groove 112 having an arc-shaped structure adapted to the shape of the arm and wrist.

[0014] The arm support 110 has an arc-shaped plate structure, and the contoured groove 112 on the upper surface is ergonomically designed so that its curvature perfectly matches the shape of the arm and wrist bones. When in use, the user places the forearm in the groove, and the curved surface of the groove can evenly distribute the pressure on the arm, avoiding fatigue caused by localized pressure.

[0015] The desktop undermount component 200 includes a horizontal fixing rod 210 and a third clamping seat 220 that slides through the horizontal fixing rod 210.

[0016] Rotate the connector 300, and the desktop upper component 100 is connected to the desktop lower component 200 through the rotating connector 300.

[0017] The arm support 110 is also provided with a little finger support 113. The little finger support 113 is rotatably connected to the front end of the arm support 110 by screws. When in use, the little finger is located at the front end of the little finger support 113, which will make the little finger and the palm a certain distance away, avoiding the hand from clenching into a fist when writing, and helping the user to form a scientific and standard writing habit.

[0018] Both ends of the arm support 110 are provided with strip holes 114. One end of the first strap 111-a and the second strap 111-b are fixedly connected to the strip hole 114 on one side, and the other end is movably inserted into the strip hole 114 on the other side.

[0019] The rotating connector 300 includes a vertical rod 310, a first clamping seat 320, a second clamping seat 330, a first longitudinal rod 340 fixedly connected to the first clamping seat 320, and a second longitudinal rod 350 fixedly connected to the second clamping seat 330, the second longitudinal rod 350 being slidably inserted into the third clamping seat 220.

[0020] As shown in the figure, the first clamping seat 320, the second clamping seat 330, and the third clamping seat 220 are all provided with hollow structures. These hollow structures are through holes, and bolt holes are provided on the outside of the through holes. By tightening the bolts, the clamping force of the first clamping seat 320, the second clamping seat 330, and the third clamping seat 220 can be increased, and the clamping force can be reduced by loosening them. Through the function of the through holes, the first clamping seat 320, the second clamping seat 330, and the third clamping seat 220 can be appropriately matched with the horizontal fixing rod 210, the vertical rod 310, the first longitudinal rod 340, and the second longitudinal rod 350.

[0021] The first strap 111-a is a strap that is far away from the human body. The main position of the first strap 111-a is the wrist bone area of ​​the hand. Its main function is to fix the wrist bone and prevent wrist flipping.

[0022] The second strap 111-b is mainly used to secure the arm portion, specifically the back of the wrist.

[0023] like Figure 7 As shown, in an incorrect writing posture, the wrist is in a bent position, i.e., a hooked wrist position. However, in use, this application, through the combined action of the first strap 111-a and the second strap 111-b, the little finger support 113, and the arm support 110, will keep the user's wrist in a position similar to... Figure 5 The straight posture shown helps users develop a good and scientific writing posture.

[0024] like Figure 8The diagram shows an incorrect writing posture where the angle between the arm and the table is too small. However, when this application is used, when the first strap 111-a and the second strap 111-b are tied together, under the action of the arm support 110 and the first strap 111-a and the second strap 111-b, the angle between the arm and the edge of the table will be maintained at 60-80°. This is also the range of the angle between the arm and the edge of the table under the correct writing posture.

[0025] The first longitudinal rod 340 is provided with a first locking ring 400 and a second locking ring 500. The first locking ring 400 is fixedly installed at the end of the first longitudinal rod 340, and the second locking ring 500 is movably installed at the other end of the first longitudinal rod 340. One end of the arm support part 110 is provided with a cavity 600, and a bearing 700 is fixedly connected to the opening of the cavity 600. The arm support part 110 is slidably inserted into the first longitudinal rod 340 through the bearing 700.

[0026] The horizontal fixing rod 210 is fixed to the bottom of the tabletop by clamps or bolts. During installation, ensure that the horizontal fixing rod 210 is parallel to the edge of the tabletop to provide a stable support base for the rotating connector 300. The horizontal fixing rod 210 is provided with a third locking ring 800 and a fourth locking ring 900, which are respectively located on the horizontal fixing rod 210 on both sides of the third clamping seat 220. The third locking ring 800 and the fourth locking ring 900 are located on the left and right sides of the third clamping seat 220, respectively, and their tightness can be adjusted by themselves. By adjusting the distance between the third locking ring 800 and the fourth locking ring 900, the movement range of the third clamping seat 220 can be limited.

[0027] The first clamping seat 320 is connected to the arm support part 110 via the first longitudinal rod 340. The arm support part 110 has a cavity 600 at one end, and a bearing 700 is installed at the opening of the cavity 600. After the first longitudinal rod 340 passes through the bearing 700, the longitudinal position of the arm support part 110 is limited by the first locking ring 400 and the second locking ring 500, thereby realizing the rotation of the arm support part 110.

[0028] The second clamping seat 330 is connected to the third clamping seat 220 via the second longitudinal rod 350. The second longitudinal rod 350 can slide through the third clamping seat 220 and, in conjunction with the lateral sliding of the horizontal fixing rod 210, enables the device to move in multiple dimensions in the horizontal plane.

[0029] like Figure 4As shown, when wearing the arm support for writing, first adjust the second locking ring 500 to a suitable position as needed. The first locking ring 400 is always fixed to the end of the first longitudinal rod 340, so there will be a distance between the first locking ring 400 and the second locking ring 500. This distance is the distance that the arm support 110 can move back and forth.

[0030] When lateral movement is required, the linkage system consisting of the first longitudinal rod 340, the first clamping seat 320, the vertical rod 310, the second clamping seat 330, the second longitudinal rod 350, and the third clamping seat 220 moves as the third clamping seat 220 moves on the horizontal fixed rod 210, and the linkage system drives the arm support part 110 to move in the horizontal direction.
