Description

Technical Field

[0001] The utility model relates to the technical field of prosthetic feet, in particular to a carbon fiber all-ground energy storage prosthetic foot. Background Art

[0002] A prosthesis is an artificial prosthesis specially designed and manufactured to compensate for amputees or those with incomplete limb loss. Its main function is to replace some of the functions of the lost limb. For leg amputees, prosthetic feet can help them regain a certain degree of self-care and work ability.

[0003] Because the muscles of the amputated limbs are broken and atrophied, it is difficult for people with amputated limbs to exert force when using existing prosthetic limbs, making walking more inconvenient. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the shortcomings of the existing technology, the present invention provides a carbon fiber all-terrain energy storage prosthetic foot to solve the technical problems of difficulty in exerting force and inconvenience in walking when using existing prosthetic limbs.

[0006] (2) Technical solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A carbon fiber all-terrain energy storage prosthetic foot comprises a connecting plate, a carbon fiber panel is installed at the bottom end of the connecting plate, a carbon fiber energy storage plate is installed at the bottom end of the carbon fiber panel, and a foot plate is installed at the bottom end of the carbon fiber energy storage plate; the carbon fiber energy storage plate is clamped in a slot opened in the foot plate, a V-shaped connector is installed between the carbon fiber panel and the foot plate, and a fixing part is installed at the bottom end of the carbon fiber panel; the carbon fiber panel is located between the connecting plate and the fixing part, a forefoot rubber pad is installed at the bottom end of the foot plate, a rearfoot rubber pad is installed at the bottom end of the foot plate, four first screws are threadedly installed on the V-shaped connector, and the carbon fiber panel and the fixing part are connected by two second screws; the two first screws are used to connect and fix the carbon fiber panel and the V-shaped connector, and the two first screws are used to connect and fix the V-shaped connector, the foot plate and the forefoot rubber pad.

[0009] Preferably, the sole plate and the rear rubber pad are connected via four third screws.

[0010] Preferably, a threaded column is fixedly mounted on the top end of the connecting plate.

[0011] (3) Beneficial effects

[0012] When walking, the heel contacts the ground before the foot, and downward pressure is shared by the V-shaped connector and the carbon fiber energy storage plate. The carbon fiber energy storage plate bears the primary pressure. During walking, pressure gradually shifts from the heel to the forefoot. The carbon fiber energy storage plate's arched structure evenly distributes pressure as the force points shift, preventing concentrated pressure and breakage. When pressure is applied to the carbon fiber energy storage plate, it deforms slightly, providing shock absorption and energy storage. When the foot is lifted, the stored energy in the carbon fiber energy storage plate is released to assist in lifting the prosthesis. During this process, the force exerted by the forefoot causes the carbon fiber panel to bend, storing energy as it bends. This elastic force is released during forward movement, assisting in propulsing the prosthesis forward. The carbon fiber panel and carbon fiber energy storage plate store energy generated by the prosthesis landing, and release this stored energy when the foot is lifted, thus assisting in lifting the foot. This achieves the effects of shock absorption, energy storage, and force generation during foot lifting, facilitating walking.

[0013] 2. When used barefoot, the rear and forefoot rubber pads can increase the friction between the sole of the foot and the ground, and can be used stably even on smooth ground, and can be applied to a variety of terrains. When the rear and forefoot rubber pads and other components are worn or damaged, the first, second, and third screws can be unscrewed to complete the disassembly, thereby facilitating the replacement of damaged components. The sole of the prosthetic foot has the same curve as the foot shape, which can be conveniently used with shoes, thereby protecting the user's self-esteem. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The embodiment of the present application provides a carbon fiber all-ground energy storage prosthetic foot plate, which effectively solves the technical problems of difficulty in exerting force and inconvenience in walking when using existing prostheses. When walking, the heel will contact the ground first, and the downward pressure will be shared by the V-shaped connector and the carbon fiber energy storage plate. Among them, the carbon fiber energy storage plate bears the main pressure. During walking, the pressure will gradually move from the heel to the forefoot. The carbon fiber energy storage plate has an arched structure, which can evenly share the pressure during the movement of the force point to avoid the pressure being concentrated at one point and causing breakage. When pressure is applied to the carbon fiber energy storage plate, the carbon fiber energy storage plate will produce a certain deformation, which can not only play a shock-absorbing effect, but also store energy. When the foot is lifted, the energy stored in the carbon fiber energy storage plate is released, which can assist in lifting the prosthesis. In the process of lifting the foot, the force exerted by the forefoot will cause the carbon fiber panel to bend, and the carbon fiber panel will bend. Energy is stored when the prosthesis is bent, and the elastic force of the carbon fiber panel is released when moving forward, which can assist in pushing the prosthesis forward. The pressure generated when the prosthesis lands is stored through the carbon fiber panel and the carbon fiber energy storage plate, and the stored energy is released when the foot is lifted to assist in lifting the foot, achieving the effect of shock absorption and energy storage for landing, and assisting in lifting the foot to facilitate walking. When used with bare feet, the rear rubber pad and the forefoot rubber pad can increase the friction between the sole of the foot and the ground, and can be used stably even on smooth ground, and can be applied to various terrains. When the rear rubber pad, the forefoot rubber pad and other components are worn or damaged, the first screw, the second screw and the third screw can be unscrewed to complete the disassembly, thereby facilitating the replacement of damaged parts. The sole of the prosthetic foot has the same curve as the foot shape, which can be conveniently used with shoes, thereby protecting the user's self-esteem.

[0021] Example

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of difficulty in exerting force and inconvenience in walking when using existing prosthetic limbs. The overall idea is as follows:

[0023] In response to the problems existing in the prior art, the utility model provides a carbon fiber all-ground energy storage prosthetic foot, including a connecting plate 1, a carbon fiber panel 2 is installed at the bottom end of the connecting plate 1, a carbon fiber energy storage plate 6 is installed at the bottom end of the carbon fiber panel 2, and a foot sole 5 is installed at the bottom end of the carbon fiber energy storage plate 6; the carbon fiber energy storage plate 6 is clamped in a slot opened on the foot sole 5, and a V-shaped connector 4 is installed between the carbon fiber panel 2 and the foot sole 5.

[0024] A fixing part 9 is installed at the bottom end of the carbon fiber panel 2; the carbon fiber panel 2 is located between the connecting plate 1 and the fixing part 9, a forefoot rubber pad 8 is installed at the bottom end of the sole plate 5, and a rearfoot rubber pad 7 is installed at the bottom end of the sole plate 5. Four first screws 11 are threadedly installed on the V-shaped connecting part 4, and the carbon fiber panel 2 and the fixing part 9 are connected by two second screws 12.

[0025] The two first screws 11 are used to connect and fix the carbon fiber panel 2 and the V-shaped connector 4. The two first screws 11 are used to connect and fix the V-shaped connector 4, the sole plate 5 and the forefoot rubber pad 8. The sole plate 5 and the rearfoot rubber pad 7 are connected by four third screws 13. A threaded column 3 is fixed on the top of the connecting plate 1.

[0026] Working principle:

[0027] The first step is to connect the connecting plate 1 to the receiving cavity through the threaded column 3 during use. When walking, the heel will contact the ground first, and the downward pressure will be shared by the V-shaped connecting piece 4 and the carbon fiber energy storage plate 6. Among them, the carbon fiber energy storage plate 6 bears the main pressure. During walking, the pressure will gradually move from the heel to the forefoot. The carbon fiber energy storage plate 6 has an arched structure. During the movement of the force point, it can evenly share the pressure to avoid the pressure being concentrated at one point and causing breakage. When pressure is applied to the carbon fiber energy storage plate 6, the carbon fiber energy storage plate 6 will produce a certain deformation. While achieving a shock-absorbing effect, it can also store energy. When the foot is lifted, the energy stored in the carbon fiber energy storage plate 6 is released, which can assist in lifting the prosthesis. In the process of lifting the foot, the force exerted by the forefoot will cause the carbon fiber panel 2 to bend, and the carbon fiber panel 2 will store energy when it bends. When moving forward, the elastic force of the carbon fiber panel 2 is released, which can assist in pushing the prosthesis forward. The pressure generated when the prosthesis lands is stored through the carbon fiber panel 2 and the carbon fiber energy storage plate 6, and the stored energy is released when the foot is lifted, completing the assistance in lifting the foot, achieving the effect of shock absorption of landing, energy storage, and auxiliary force for lifting the foot to facilitate walking.

[0028] In the second step, when used barefoot, the rear rubber pad 7 and the forefoot rubber pad 8 can increase the friction between the sole of the foot and the ground, and can be used stably even on smooth ground, and can be applied to various terrains. When the rear rubber pad 7, the forefoot rubber pad 8 and other components are worn or damaged, the first screw 11, the second screw 12, and the third screw 13 can be unscrewed to complete the disassembly, thereby achieving the effect of facilitating the replacement of damaged parts. The sole of the prosthetic foot has the same curve as the foot shape, which can be conveniently used with shoes, thereby achieving the effect of protecting the user's self-esteem.

[0029] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
