Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of prosthetics, and more specifically, to a carbon fiber prosthetic footplate. Background Technology

[0002] A carbon fiber prosthetic footplate is a prosthetic footplate made of carbon fiber material. Due to its high strength, low weight and excellent impact resistance, carbon fiber is widely used in high-performance fields such as sports, aviation and automobiles. Applying this material to prostheses can provide users with greater stability, comfort and flexibility.

[0003] A carbon fiber composite prosthetic foot (publication number: CN205041572U) in the prior art includes an upper foot plate and a lower foot plate; the upper foot plate includes a C-shaped plate, the lower end of which extends into a lower plate and the upper end of which extends into a top plate; the forefoot of the lower foot plate is a downwardly convex arc and the arch of the foot is an upwardly convex arc; the lower plate is fixed to the forefoot.

[0004] Because different people have different walking habits, some use their toes more and some use their heels more, the detachable design allows for individual replacement when a part wears out, instead of replacing the whole thing, thus reducing costs.

[0005] However, the aforementioned device, with its C-shaped plate, lower foot plate, and lower plate working together, makes it difficult to achieve the effect of detaching the front and rear foot plates. This makes it difficult for users to easily disassemble and replace the front and rear foot plates, increases the maintenance and replacement costs of the prosthetic foot, makes it difficult to avoid damage caused by improper use, and reduces the service life of the prosthetic foot. Therefore, improvements are needed. Utility Model Content

[0006] To overcome the above-mentioned defects, embodiments of this disclosure provide a carbon fiber prosthetic foot plate, which solves the technical problems in related technologies / prior technologies, such as the difficulty for users to easily disassemble and replace the front and rear foot plates, the increased maintenance and replacement costs of prosthetic feet, the difficulty in avoiding damage caused by improper use, and the reduced service life of prosthetic feet.

[0007] According to one aspect, at least one embodiment of this disclosure provides a carbon fiber prosthetic footplate, including a front footplate, a rear footplate disposed on the side of the front footplate, and a mounting base disposed on the top of the rear footplate; The front foot plate is provided with a disassembly device, which includes a protective shell. The protective shell is fixedly connected to the side of the front foot plate. A support rod extends through the side of the protective shell. A disc is fixedly connected to one end of the support rod, and an installation block is fixedly connected to the other end of the support rod. A fixing plate is fixedly connected to the inner wall of the protective shell. A fixing block is fixedly connected to the side of the rear foot plate, and a positioning block is fixedly connected to the side of the fixing block.

[0008] For example, in at least one embodiment of the present disclosure, a carbon fiber prosthetic footplate is provided, wherein the side of the mounting block is set as an inclined surface and the side of the positioning block is set as an inclined surface. The inclined surface design of the mounting block and the positioning block is beneficial to fixing the front footplate and the rear footplate, thereby increasing the stability between the footplates.

[0009] A spring is fixedly connected to the side of the fixing plate. The end of the spring away from the fixing plate is fixedly connected to the circumferential surface of the support rod. When the front foot plate and the rear foot plate are fixed by the mounting block and the positioning block, the mounting block is reset by the elastic force of the spring, ensuring that it is firmly inserted into the positioning block.

[0010] The spring is initially in a relaxed state, and the mounting block is located on the movement trajectory of the positioning block. The spring design facilitates the automatic reset of the mounting block, reducing manual intervention.

[0011] According to another aspect, at least one embodiment of this disclosure also provides a carbon fiber prosthetic foot plate, wherein the disassembly device includes a limiting structure, the limiting structure includes a hydraulic cylinder, the hydraulic cylinder is fixedly connected to the inner wall of the front foot plate, one end of the hydraulic cylinder is slidably connected to a force-bearing rod via a piston, the other end of the hydraulic cylinder is slidably connected to a hydraulic rod via a piston, a protective pad is fixedly connected to the end of the force-bearing rod away from the hydraulic cylinder, and a mounting plate is fixedly connected to the end of the hydraulic rod away from the force-bearing rod.

[0012] For example, in at least one embodiment of the present disclosure, a carbon fiber prosthetic foot plate is provided, which further includes a disc located on the movement trajectory of the mounting plate, and a force-bearing rod passing through the top of the front foot plate. When the front foot plate is subjected to force, the displacement of the disc is restricted by a hydraulic system, so that the disc cannot move.

[0013] A return spring is fixedly connected to the side of the hydraulic cylinder. The end of the return spring away from the hydraulic cylinder is fixedly connected to the circumferential surface of the force-bearing rod. The design of the return spring helps the force-bearing rod to automatically return to its original position, reducing manual intervention.

[0014] The initial state of the return spring is relaxed, and the hydraulic cylinder is L-shaped. The design of the hydraulic cylinder enables the entire system to efficiently transmit and adjust the force, ensuring the stability and reliability of the footplate.

[0015] The protective shells are set to two in number and are symmetrical to each other along the vertical central axis of the front foot plate. The design of the protective shells increases the stability of the foot plate.

[0016] The springs are set to two and are symmetrical about each other along the vertical center axis of the front footplate. The spring design allows users to easily disassemble and replace the front and rear footplates, reducing the maintenance and replacement costs of the prosthetic foot.

[0017] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, by combining the force of the front and rear foot plates moving closer together with the components such as the mounting block, fixing block, and positioning block in the disassembly device, the disc is pulled to move the support rod, which in turn moves the mounting block, causing it to disengage from the positioning block. This completes the disassembly, allowing the front and rear foot plates to be easily removed and replaced. This reduces the maintenance and replacement costs of the prosthetic foot, avoids damage caused by improper use, and extends the service life of the prosthetic foot.

[0018] In this disclosure, the force that causes the force rod to move downward by the downward displacement of the protective pad works in conjunction with the components such as the protective pad, hydraulic cylinder, and hydraulic rod in the disassembly device. This enables the liquid inside the hydraulic cylinder to push another piston to move, the piston to push the hydraulic rod to move, and the hydraulic rod to push the mounting plate to move, thus limiting the disk by the mounting plate. At this time, the disk cannot move, achieving the effect that the footboard cannot be disassembled during use, increasing the safety of the device. Users do not need to worry about the footboard being unnecessarily disassembled or displaced while walking, thereby reducing possible accidental injuries. Attached Figure Description

Detailed Implementation

[0022] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0023] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0024] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0025] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-5 As shown, a carbon fiber prosthetic foot plate is provided in one embodiment of the present disclosure, including a front foot plate 101, a rear foot plate 102 is provided on the side of the front foot plate 101, and a mounting base 103 is provided on the top of the rear foot plate 102. A disassembly device 2 is provided on the side of the front foot plate 101. The disassembly device 2 includes a protective shell 201, which is fixedly connected to the side of the front foot plate 101. A support rod 203 passes through the side of the protective shell 201. A disc 205 is fixedly connected to one end of the support rod 203, and an installation block 206 is fixedly connected to the other end of the support rod 203. A fixing plate 202 is fixedly connected to the inner wall of the protective shell 201. A fixing block 207 is fixedly connected to the side of the rear foot plate 102, and a positioning block 208 is fixedly connected to the side of the fixing block 207.

[0029] In some examples, the sides of the mounting block 206 and the positioning block 208 are also beveled. The beveled design of the mounting block 206 and the positioning block 208 is beneficial for fixing the front foot plate 101 and the rear foot plate 102, and increases the stability between the foot plates.

[0030] A spring 204 is fixedly connected to the side of the fixing plate 202. The end of the spring 204 away from the fixing plate 202 is fixedly connected to the circumferential surface of the support rod 203. When the front foot plate 101 and the rear foot plate 102 are fixed by the mounting block 206 and the positioning block 208, the mounting block 206 is reset by the elastic force of the spring 204, ensuring that it is firmly inserted into the positioning block 208.

[0031] The initial state of spring 204 is relaxed, and the mounting block 206 is located on the movement trajectory of the positioning block 208. The design of spring 204 helps to automatically reset the mounting block 206, reducing manual intervention.

[0032] For example, such as Figures 1-5As shown, this application moves the front foot plate 101 and rear foot plate 102 closer together. Pressing the front foot plate 101 causes it to move the protective shell 201, which in turn moves the fixing plate 202. The fixing plate 202 then moves the support rod 203, which in turn moves the mounting block 206. The inclined surface of the mounting block 206 is then compressed by the positioning block 208, causing it to move. This movement of the mounting block 206 further moves the support rod 203. The spring 2 on the side of the support rod 203... When the mounting block 206 is compressed and moves into the interior of the positioning block 208, the mounting block 206 is reset by the elastic force of the spring 204, thus locking the mounting block 206 into the interior of the positioning block 208 and fixing the front foot plate 101 and the rear foot plate 102. When disassembly is required, the disc 205 is pulled to move the support rod 203. The displacement of the support rod 203 causes the mounting block 206 to move, thus disassembling the mounting block 206 from the positioning block 208 and completing the disassembly. This achieves the function of disassembling the front foot plate 101 and the rear foot plate 102.

[0033] like Figures 1-5 As shown, a carbon fiber prosthetic foot plate is illustrated in another embodiment of this disclosure. The disassembly device 2 includes a limiting structure, which includes a hydraulic cylinder 209. The hydraulic cylinder 209 is fixedly connected to the inner wall of the front foot plate 101. One end of the hydraulic cylinder 209 is slidably connected to a force rod 210 via a piston, and the other end of the hydraulic cylinder 209 is slidably connected to a hydraulic rod 211 via a piston. A protective pad 214 is fixedly connected to the end of the force rod 210 away from the hydraulic cylinder 209, and a mounting plate 212 is fixedly connected to the end of the hydraulic rod 211 away from the force rod 210. In some examples, the disc 205 is located on the movement trajectory of the mounting plate 212, and the force-bearing rod 210 passes through the top of the front foot plate 101. The hydraulic system restricts the displacement of the disc 205 when the front foot plate 101 is under force, so that the disc 205 cannot move.

[0034] A return spring 213 is fixedly connected to the side of the hydraulic cylinder 209. The end of the return spring 213 away from the hydraulic cylinder 209 is fixedly connected to the circumferential surface of the force rod 210. The design of the return spring 213 is conducive to the automatic reset of the force rod 210, reducing manual intervention.

[0035] The initial state of the return spring 213 is relaxed. The hydraulic cylinder 209 is L-shaped. The design of the hydraulic cylinder 209 enables the entire system to efficiently transmit and adjust the force, ensuring the stability and reliability of the foot plate.

[0036] The number of protective shells 201 is set to two, and they are symmetrical to each other along the vertical central axis of the front foot plate 101. The design of the protective shells 201 increases the stability of the foot plate.

[0037] The number of springs 204 is set to two, and they are symmetrical to each other along the vertical central axis of the front foot plate 101. The design of the springs 204 allows users to easily disassemble and replace the front foot plate 101 and the rear foot plate 102, thereby reducing the maintenance and replacement cost of the prosthetic foot.

[0038] For example, such as Figures 1-5 As shown, when the footplate is in use, the front footplate 101 will be subjected to force, pressing the protective pad 214 downward. The downward displacement of the protective pad 214 will drive the force rod 210 downward, causing the force rod 210 to move inward and squeeze the piston inside the hydraulic cylinder 209. The piston inside the hydraulic cylinder 209 pushes the liquid inside it, and the liquid inside the hydraulic cylinder 209 pushes another piston to move. The piston pushes the hydraulic rod 211 to move, and the hydraulic rod 211 pushes the mounting plate 212 to move, so that the mounting plate 212 limits the disc 205. At this time, the disc 205 cannot move, that is, the footplate cannot be disassembled during use, which increases the safety of the device.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
