Technical Field
[0001] The utility model relates to the technical field of artificial limb foot plates, in particular to a carbon fiber foot plate for a dynamic ankle cushioning artificial limb. Background Art
[0002] In order to help people with leg amputations or below to walk or exercise normally, foot prostheses have emerged. These tools simulate the human body to fill limb defects. Among the prosthetic limbs, the prosthetic foot is for people whose users are missing the soles of their feet. It mainly replaces the function of the human foot and helps the user to walk or do other exercises.
[0003] Currently, the prosthetic foot plates on the market are made of carbon fiber, but the connecting structures on the plates are generally made of aluminum alloy due to their shape. When people wear prosthetic feet for exercise, not only the plate itself will be subjected to impact force, but the connecting structures on it will also be subjected to impact force. However, aluminum alloy material does not have the good elastic deformation ability like carbon fiber. Prolonged impact force will cause it to be permanently deformed and eventually scrapped. Utility Model Content

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a carbon fiber footplate for a dynamic ankle cushioning prosthesis, comprising a connecting seat, an extension block fixedly connected to the middle of the upper surface of the connecting seat, both side surfaces of the extension block are laterally fixedly connected to a horizontal axis, the outer surfaces of the two horizontal axes are rotatably connected to a rotating ring, the top end between the two rotating rings is fixedly connected to a cap, the front and rear end surfaces of the cap are respectively laterally fixedly connected to a front extension seat and a rear extension seat, the front and rear ends of the upper surface of the connecting seat are respectively fixedly connected to a front buffer block and a rear buffer block, the upper surfaces of the front buffer block and the rear buffer block are respectively fitted to the lower surfaces of the front extension seat and the rear extension seat.
[0006] Furthermore, a locking piece is fixedly connected to the top of the cap.
[0007] Furthermore, the bottom end of the connecting seat is fixedly connected to a first foot plate, and the lower surface of the front end of the first foot plate is fixedly connected to a second foot plate.
[0008] Furthermore, the rear portion of the second foot plate is bent downward to form a full-length sole, and the end of the rear portion of the second foot plate is tilted upward to form an arc-shaped heel.
[0009] Furthermore, a groove extending toward the connecting seat is transversely formed at the middle portion of the front end of each of the first foot plate and the second foot plate.
[0010] Furthermore, the first foot plate and the second foot plate are both made of carbon fiber.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the carbon fiber footplate of the dynamic ankle buffer prosthesis is provided with a front buffer block and a rear buffer block, and the connection structure of the device is divided into two parts. The lower connecting seat is used to be directly connected to the footplate, and a cap that can swing back and forth is provided on the upper part. The front and rear ends of the cap are fixedly connected to the front extension seat and the rear extension seat respectively. The three are cast as one body, and their top-view contours are adapted to the connecting seat, so the upper surfaces of the front buffer block and the rear buffer block fixedly connected to the front and rear ends of the connecting seat can be respectively fitted with the lower surfaces of the front extension seat and the rear extension seat. The front buffer block and the rear buffer block can reduce the impact force received by the entire connecting structure during movement, so that it is no longer easy to deform, thereby improving its service life.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-3 The utility model provides a technical solution: a carbon fiber footplate of a dynamic ankle cushioning prosthesis, including a connecting seat 1, an extension block 6 is fixedly connected to the middle part of the upper surface of the connecting seat 1, and both side surfaces of the extension block 6 are transversely fixedly connected to a transverse axis 7, the outer surfaces of the two transverse axes 7 are rotatably connected to a rotating ring 8, and a cap 9 is fixedly connected to the top between the two rotating rings 8, and the front and rear end surfaces of the cap 9 are respectively transversely fixedly connected to a front extension seat 10 and a rear extension seat 11, and the front and rear end of the upper surface of the connecting seat 1 are respectively fixedly connected to a front buffer block 12 and a rear buffer block 13, and the upper surfaces of the front buffer block 12 and the rear buffer block 13 are respectively fitted to the lower surfaces of the front extension seat 10 and the rear extension seat 11.
[0020] The connection structure of the device is divided into two parts. The lower connection seat 1 is used to be directly connected to the foot plate, and a cap 9 that can swing back and forth is provided on the top. The front and rear ends of the cap 9 are fixedly connected to the front extension seat 10 and the rear extension seat 11 respectively. The three are cast as one body, and its top-view profile is adapted to the connection seat 1. Therefore, the upper surfaces of the front buffer block 12 and the rear buffer block 13 fixedly connected to the front and rear ends of the connection seat 1 can be respectively fitted with the lower surfaces of the front extension seat 10 and the rear extension seat 11. The front buffer block 12 and the rear buffer block 13 can reduce the impact force received by the entire connection structure during movement, so that it is no longer easily deformed, thereby improving its service life.
[0021] The front buffer block 12 and the rear buffer block 13 are both made of rubber, which can effectively absorb impact and recover quickly.
[0022] A locking piece 14 is fixedly connected to the top of the cap 9 .
[0023] The locking member 14 is used to connect to a lower leg prosthesis or a lower leg connecting component.
[0024] The bottom end of the connecting base 1 is fixedly connected to a first foot plate 2 , and the lower surface of the front end of the first foot plate 2 is fixedly connected to a second foot plate 3 .

[0027] The full-length sole and the curved heel 4 can simulate the real sole contour, while the inter-groove 5 can simulate the real toe structure, which enables the wearer to adapt more quickly after wearing it and ensures smooth movement.
[0028] The groove 5 on the second foot plate 3 can also be inserted into the Figure 5As shown, the second foot plate 3 is completely separated. When the heel of the second foot plate 3 contacts the uneven road surface, the heel-toe separation can effectively achieve balance and fully bear the force on the ground.
[0029] The first foot plate 2 and the second foot plate 3 are both made of carbon fiber.
[0030] Carbon fiber has high stiffness, is lightweight, and has strong shock absorption, making it the preferred material for prosthetic foot plates.
