Description

Technical Field

[0001] This invention relates to the field of personal transportation tools, and more specifically to electric powered shoes. Background Technology

[0002] Electric powered shoes are a new type of personal transportation that uses electricity to drive its wheels, propelling the user forward. Unlike other modes of transportation, electric powered shoes are highly portable, allowing users to walk, climb stairs, and perform other activities while wearing them.

[0003] Existing electric power shoes have soles consisting of two parts that rotate relative to each other via a hinge, and each part is equipped with a gravity sensor. Different gravity sensors receive pressure from different locations on the user's foot and output signals to the shoe's control module based on the magnitude of the received pressure. However, these electric power shoes cannot adapt to the different foot movements of various individuals, making it difficult for some users to control the shoes by applying force with their feet.

[0044] Electric powered shoes are a new type of personal transportation that uses electricity to drive its wheels, propelling the user forward. Unlike other modes of transportation, electric powered shoes are highly portable, allowing users to walk, climb stairs, and perform other activities while wearing them.

[0045] Existing electric motorized shoes incorporate gravity sensors in the sole. These sensors detect foot pressure and use it to control the shoe's acceleration, deceleration, or stopping. However, current gravity sensors are located either on the foot-facing side of the sole or within a cavity in the sole's midsole, leading to inconsistent pressure readings.

[0046] Specifically, the inventors discovered in practice that because existing electric power shoes place the gravity sensor directly on the surface of the shoe to support the foot, or place it between the layers of the shoe, when the user's foot steps on the sole located next to the gravity sensor, the sole directly transmits the pressure downward to the ground, and the gravity sensor does not generate a corresponding signal. The control module has difficulty knowing the user's current state based on the gravity sensor, which is not conducive to adjusting the behavior mode of the electric power shoes.

[0047] In view of this, please refer to Figures 1 to 11As shown, the present invention proposes an electric power shoe 10, including a sole 100, a base 200, and a gravity sensor 300. The sole 100 supports the foot. The base 200 is located below the sole 100 and is for contact with the ground. The gravity sensor 300 includes a fixing part 310 and a strain part 320. The strain part 320 is connected to the fixing part 310 and can output a signal when deformed relative to the fixing part 310; the sole 100 is connected to the strain part 320, and the fixing part 310 is connected to the base 200.

[0048] Since the base 200 is located below the sole 100 and is connected to the strain section 320 and the fixing section 310 of the gravity sensor 300 respectively, when the user steps on the sole 100, the pressure on the sole 100 is transmitted to the base 200 through the gravity sensor 300. The pressure exerted by the user on the sole 100 causes relative deformation of the fixing section 310 and the strain section 320 of the gravity sensor 300, thereby causing the gravity sensor 300 to output a signal. Furthermore, since the sole 100 is connected to the base 200 through the gravity sensor 300, the pressure exerted by the user on the sole 100 while walking, gliding, and climbing stairs while wearing the electric power shoe 10 of this invention can be directly transmitted to the gravity sensor 300. This allows the gravity sensor 300 to generate different signals based on the magnitude of the pressure exerted by the user on the sole 100, which is beneficial for the electric power shoe 10 to adjust its behavior pattern according to the signals from the gravity sensor 300.

[0049] It should be understood that the base 200 in this invention is for contacting the ground, the sole 100 is for supporting the foot, and the base 200 is connected to the gravity sensor 300, so that the gravity sensor 300 can directly bear the pressure on the sole 100. Based on the above inventive concept, those skilled in the art can make further modifications. Exemplarily, in some embodiments, the base 200 also includes an axle, the strain section 320 of the gravity sensor 300 is connected to the sole 100, and the fixing part 310 is rotatably connected to the axle.

[0050] In some embodiments, the sole 100 further includes an insole 180, which is made of an elastic material and supports the foot through the insole 180. Through this design, the elastic insole 180 can deform when pressure is applied to the foot, thereby better adapting to the shape of the foot, improving the user's comfort when using the electric power shoe 10, and enhancing the user experience.

[0051] Without departing from the inventive concept of this invention, those skilled in the art can further adjust the structure of the gravity sensor 300. Please refer to... Figure 7As shown, in some embodiments, the strain section 320 and the fixed section 310 of the gravity sensor 300 are connected by a cantilever beam structure. In some embodiments, the gravity sensor 300 further includes a strain gauge disposed on the surface of the strain section 320 and abutting the sole 200. The strain gauge can output a signal when the strain section 320 deforms relative to the fixed section 310. This design allows the sole 200 to apply pressure to the strain section 320, causing the strain gauge to deform, thereby changing the resistance of the strain gauge and outputting a resistance change signal.

[0052] Further, please refer to Figure 6 As shown, in some embodiments, the sole 100 includes a ball portion 110 and a toe portion 120. The ball portion 110 supports the ball of the foot, and the toe portion 120 supports the toes; the ball portion 110 and the toe portion 120 are movably connected. Through the movable connection of the ball portion 110 and the toe portion 120, the base 200 can deform accordingly according to the movement of the user's foot, which is beneficial for adapting to the movement of the user's foot. Exemplarily, in some embodiments, the ball portion 110 and the toe portion 120 are rotatably connected, and the rotation axes of the ball portion 110 and the toe portion 120 are parallel to a second direction, with the second direction, the first direction, and the vertical direction being perpendicular to each other. In the above-described solution, the toe portion 120 and the ball portion 110 can rotate relative to each other around the second direction, thereby following the rotation of the user's toes relative to the ball of the foot, making it easier for the user to perform a pushing-off action when using the electric power shoe 10.

[0053] Based on the movable connection between the ball of the foot 110 and the toes 120, please refer to Figure 6 , Figure 7 As shown, the base 200 includes a first seat 210 and a second seat 220. The electric power shoe 10 includes a plurality of gravity sensors 300, at least one gravity sensor 300 is defined as a first gravity sensor 300A, and at least one gravity sensor 300 is defined as a second gravity sensor 300B; the foot part 110 is connected to the strain portion 320 of the first gravity sensor 300A, the first seat 210 is connected to the fixing portion 310 of the first gravity sensor 300A; the toe part 120 is connected to the strain portion 320 of the second gravity sensor 300B, and the second seat 220 is connected to the fixing portion 310 of the second gravity sensor 300B.

[0054] With the above scheme, the foot part 110 is connected to the first base 210 through the first gravity sensor 300A, and the toe part 120 is connected to the second base 220 through the second gravity sensor 300B. Thus, the first gravity sensor 300A and the second gravity sensor 300B can work together to bear the pressure exerted by the user on the sole 100. Since the foot part 110 and the toe part 120 are movably connected, during the relative movement of the foot part 110 and the toe part 120, the first gravity sensor 300A and the first base 210 can move together with the foot part 110, and the second gravity sensor 300B and the second base 220 can move together with the toe part 120. The first gravity sensor 300A can receive the pressure exerted by the foot on the sole 110 and output a signal during the relative movement of the sole 110 and the toe 120. The second gravity sensor 300B can receive the pressure exerted by the foot on the toe 120 and output a signal during the relative movement of the sole 110 and the toe 120, thereby enabling the gravity sensor 300 to receive the pressure exerted by the toes and sole on the sole 100 respectively.

[0055] Furthermore, in some embodiments, the foot portion 110 is connected to the strain portions 320 of the two first gravity sensors 300A, and the fixing portions 310 of the two first gravity sensors 300A are connected to the first base 210. The two first gravity sensors 300A are arranged along a first direction, which is the direction from the foot portion 110 to the toe portion 120. With the above solution, since the two first gravity sensors 300A are arranged along the first direction, the two first gravity sensors 300A can respectively receive the pressure applied by different parts of the foot in the first direction, thereby enabling the gravity sensors 300 to receive the pressure exerted by the forefoot and heel on the sole 100 respectively.

[0056] It should be noted that the present invention does not limit the number of strain sections 320 in the gravity sensor 300. In some embodiments, the first gravity sensor 300A includes two strain sections 320, which are arranged along a second direction and connected to different positions of the foot portion 110, with the first direction, the second direction, and the vertical direction being perpendicular to each other. Through this scheme, the two strain sections 320 arranged along the second direction can respectively receive the pressure applied by different parts of the foot in the first direction, thereby enabling the gravity sensor 300 to receive the pressure exerted on the sole 100 by the inner and outer sides of the foot.

[0057] As a preferred option, please refer to Figure 6As shown, in some embodiments, at least one gravity sensor 300 is defined as a third gravity sensor 300C; the foot portion 110 is connected to the strain portion 320 of two third gravity sensors 300C, and the fixing portion 310 of the two third gravity sensors 300C is connected to the first base 210. One third gravity sensor 300C is located on one side of a first gravity sensor 300A in the second direction, and the other third gravity sensor 300C is located on one side of another first gravity sensor 300A in the second direction. The first direction, the second direction, and the vertical direction are perpendicular to each other. With the above scheme, the first gravity sensor 300A and the third gravity sensor 300C arranged along the second direction can respectively receive the pressure applied by different parts of the foot in the first direction, thereby enabling the gravity sensor 300 to receive the pressure exerted on the sole 100 by the inner and outer sides of the foot respectively. On the other hand, the first gravity sensor 300A and the third gravity sensor 300C can output signals separately based on the pressure on the inner and outer sides of the foot, reducing signal coupling, which is beneficial for the electric power shoe 10 to process data and adjust the movement mode.

[0058] Based on the above-described inventive concept, those skilled in the art can adjust the positions of the first gravity sensor 300A, the second gravity sensor 300B, and the third gravity sensor 300C according to the foot sizes of different individuals. For example, the electric power shoe 10 includes multiple pulleys rotatably connected to the base 200 and used to move the base 200 along a first direction. The strain section 320 of each gravity sensor 300 is positioned in the first direction at the same position as the different pulleys.

[0059] Without departing from the inventive concept of this invention, those skilled in the art can choose the connection method between the base 200 and the fixing part 310, and between the base 200 and the fixing part 310. The connection method can be adhesive bonding, snap-fitting, or fixed bonding, etc.

[0060] As a preferred embodiment, in some embodiments, the foot portion 110 is threaded vertically to the strain portion 320 of the first gravity sensor 300A and the strain portion 320 of the third gravity sensor 300C, and the first base 210 is threaded vertically to the fixing portion 310 of the first gravity sensor 300A and the fixing portion 310 of the third gravity sensor 300C. With this design, the pressure borne by the foot portion 110 can be transmitted to the strain portions 320 of the first gravity sensor 300A and the third gravity sensor 300C through the threads, thereby enabling the first gravity sensor 300A and the third gravity sensor 300C to receive the pressure exerted on the sole 100 by the inner and outer sides of the foot, respectively. Furthermore, the threaded connection facilitates the disassembly of the gravity sensor 300 by technicians, thus facilitating maintenance of the electric power shoe 10.

[0061] In addition to the threaded connection, in some embodiments, the electric power shoe 10 further includes at least two screws, both extending vertically. The upper end of one screw is threaded to the foot portion 110, and the lower end of the screw is threaded to the strain section 320 of the first gravity sensor 300A. The upper end of the other screw is threaded to the foot portion 110, and the lower end of the screw is threaded to the strain section 320 of the third gravity sensor 300C. There is a gap between the foot portion 110 and the strain section 320.

[0062] With the above scheme, when the foot part 110 is subjected to pressure, the foot part 110 transmits the pressure to the upper end of the two screws through the threaded connection with the screw. The upper end of the two screws transmits the pressure to the lower end of the screw in the vertical direction. The lower end of the two screws transmits the pressure to the first gravity sensor 300A and the third gravity sensor 300C respectively through the thread. Since the strain unit 320 is spaced from the foot part 110, the above threaded connection can avoid the screws from generating preload on the strain unit 320, reduce the deformation of the strain unit 320 caused by the threaded connection, and help improve the accuracy of the output signal of the gravity sensor 300. On the other hand, since the foot part 110 is connected to the first gravity sensor 300A and the third gravity sensor 300C respectively through two screws, the above solution can also restrict the rotation of the foot part 110 through the two screws. The user can more intuitively adjust the posture of the electric power shoe 10 through foot movement, which helps to reduce the time required for the user to master the electric power shoe 10 and reduce the practice cost.

[0063] It should be noted that the present invention does not limit the number of fixing parts 310 of the gravity sensor 300. Please refer to Figure 6 , Figure 7As shown, in some embodiments, the gravity sensor 300 includes multiple fixing parts 310, all of which are connected to the base 200. Through this design, the gravity sensor 300 can be more securely fixed to the base 200.

[0064] Please refer to Figure 4 As shown, in some embodiments, the sole 100 further includes a guide post 140, which is connected to the lower side of the toe portion 120 and slidably connected in the vertical direction to the second seat 220 and the fixing part 310 of the second gravity sensor 300B. Through this design, the guide post 140 can restrict the horizontal movement between the second seat 220, the fixing part 310 of the second gravity sensor 300B, and the first seat 210, thereby improving the stability of the connection between the toe portion 120 and the first seat 210.

[0065] Those skilled in the art can choose the specific method by which the guide post 140 is connected to the lower side of the toe portion 120. In some embodiments, the upper end of the guide post 140 is provided with threads, and the upper end of the guide post 140 is connected to the lower side of the toe portion 120 through the threads and abuts against the lower side of the toe portion 120. The above solution allows the other parts of the guide post 140 to maintain a sliding connection with the fixing part 310 of the second gravity sensor 300B, while maintaining a sliding connection with the second seat 220, which helps to reduce the interaction force between the second seat 220 and the toe portion 120 and improve the accuracy of the signal collected by the second gravity sensor 300B.

[0066] Further, please refer to Figure 4 As shown, in some embodiments, the sole 100 further includes multiple guide posts 140, each guide post 140 being connected to the underside of the toe portion 120 and slidably connected vertically to the first seat 210 and the fixing portion 310 of the same second gravity sensor 300B. Through this design, the multiple guide posts 140 can further restrict the horizontal movement between the second seat 220, the fixing portion 310 of the second gravity sensor 300B, and the first seat 210, thereby improving the stability of the connection between the toe portion 120 and the first seat 210. On the other hand, the above design also allows the first seat 210 to restrict the rotation of the foot portion 110 through the two guide posts 140, enabling the user to more intuitively adjust the posture of the electric power shoe 10 through foot movements, which helps reduce the time required for the user to master the electric power shoe 10 and lowers the practice cost.

[0067] Furthermore, in some embodiments, the sole 100 further includes a plurality of limiting portions 150, each limiting portion 150 being connected to the lower side of a different guide post 140 and protruding relative to the side of the guide post 140; the upper side of the limiting portion 150 abuts against the lower side of the second seat 220. The toe portion 120 has a downward-facing first abutting plane 130, and the strain portion 320 has an upward-facing second abutting plane 321, the first abutting plane 130 abutting against the second abutting plane 321, the second abutting plane 321 being larger than the first abutting plane 130. With the above solution, since the guide post 140 is also connected to the lower side of the toe portion 120, the second seat 220, which is slidably connected to the guide post 140, will be limited in the vertical direction by the toe portion 120 and the limiting portions 150. Through the mutual contact of the first abutting plane 130 and the second abutting plane 321, the toe portion 120 can restrict the position of the second gravity sensor 300B in the vertical direction. Since the second abutting plane 321 is larger than the first abutting plane 130, the toe portion 120 can move horizontally relative to the strain portion 320 of the second gravity sensor 300B. This reduces the horizontal force exerted by the toe portion 120 on the strain portion 320 of the second gravity sensor 300B during the movement of the electric power shoe 10, which helps the second gravity sensor 300B to collect more accurate pressure data.

[0068] Those skilled in the art can further adjust the degree of contact between the first abutting plane 130 and the second abutting plane 321. As one embodiment, the first abutting plane 130 is precisely in contact with the second abutting plane 321. This solution can further reduce the impact of deformation of the strain portion 320 on the signal when the first abutting plane 130 abuts the second abutting plane 321.

[0069] Please refer to Figure 4 , Figure 10 As shown, in some embodiments, the sole 100 includes a panel 160 and a protrusion 170. The panel 160 supports the foot, and the protrusion 170 is connected to the lower side of the panel 160 and to the strain section 320. The panel 160 and the fixing part 310 are spaced apart in the vertical direction. The base 200 has a downwardly recessed relief groove 230, and the bottom wall of the relief groove 230 is spaced apart from the strain section 320 in the vertical direction. With this design, after the panel 160 bears the pressure of the foot, the pressure can be transmitted to the strain section 320 through the protrusion 170, which protrudes downward relative to the panel 160. This allows the strain section 320 to deform under the pressure of the protrusion 170, reducing the possibility of contact between the panel 160 and the fixing part 310 and improving the accuracy of the output signal of the gravity sensor 300. The recessed relief groove 230 on the base 200 can also provide space for the strain unit 320 to deform downwards, reducing the possibility of the strain unit 320 contacting the base 200 and improving the accuracy of the output signal of the gravity sensor 300.

[0070] Further, please refer to Figure 6 , Figure 8 As shown, in some embodiments, the electric power shoe 10 includes a limiting post 400 located between the panel 160 and the base 200; the limiting post 400 is connected to the base 200 and has a gap in the vertical direction with respect to the panel 160. When the sole 100 deforms downward by pressing the strain portion 320 through the protrusion 170, the entire panel 160 also moves downward following the deformation of the strain portion 320. Since the limiting post 400 fills part of the space between the panel 160 and the base 200, the downward movement of the entire panel 160 can be limited by the limiting post 400, thereby limiting the maximum deformation of the strain portion 320 and preventing the strain portion 320 from undergoing plastic deformation relative to the fixed portion 310.

[0071] Please refer to Figure 6 , Figure 8 As shown, in some embodiments, the electric power shoe 10 also includes a cable, one end of which is signal-connected to the gravity sensor 300. The base 200 has a cable routing groove 240, in which the cable portion is housed. The cable signal-connected to the gravity sensor 300 can transmit pressure data measured by the gravity sensor 300 to other parts of the electric power shoe 10. The cable portion being housed in the cable routing groove 240 of the base 200 protects the cable, preventing direct contact with the external environment and improving the stability of the electric power shoe 10.

[0072] Please refer to Figure 6 As shown, in some embodiments, the electric power shoe 10 further includes a dustproof component 600, which is disposed in the horizontal direction of the gravity sensor 300. Through this solution, the dustproof component 600 can block external dust, thereby reducing the possibility of the gravity sensor 300 coming into contact with dust and improving the electrical stability of the gravity sensor 300 during long-term use.

[0073] As previously described, the sole 100 is adapted to the user's foot movements by movably connecting the forefoot portion 110 and the toe portion 120. In the prior art, to enable electric power shoes to adapt to the relative flexion between the toes and the forefoot, the sole of existing electric power shoes is divided into two parts, which rotate relative to each other via a mechanical hinge. However, the aforementioned electric power shoes cannot adapt to the foot movements of different individuals.

[0074] Through long-term practice, the inventors discovered that since the two parts of the sole of existing electric power shoes are directly rotated relative to each other through mechanical hinges and the axis of rotation of the two parts is fixed, users need to align the joints between their toes and the ball of their foot with the aforementioned axis of rotation when using existing electric power shoes, making it difficult for electric power shoes to adapt to the foot movements of different people.

[0075] In view of this, please refer to Figures 1 to 11 As shown, in some embodiments, the electric power shoe 10 includes a sole 100, which includes a ball portion 110 and a toe portion 120. The ball portion 110 is used to support the ball of the foot and includes a first connecting portion 111. The toe portion 120 is used to support the toes and includes a second connecting portion 121. The first connecting portion 111 and the second connecting portion 121 are spaced apart and elastically connected in a first direction, which is the direction from the ball portion 110 to the toe portion 120.

[0076] Through the above solution, the foot portion 110 and the toe portion 120 are elastically connected by the first connecting portion 111 and the second connecting portion 121, allowing them to deform accordingly according to the user's foot movements, thus facilitating adaptation to the user's foot movements. Furthermore, since the first connecting portion 111 and the second connecting portion 121 are spaced apart and elastically connected in the first direction, the toe portion 120 can rotate relative to the foot portion 110 using the elastic portion between the first connecting portion 111 and the second connecting portion 121 as its axis of rotation, thereby adapting to the foot rotation of different individuals.

[0077] The following specific examples illustrate the superiority of this embodiment in adapting to foot movements. Specifically, the relative positions of the ball of the foot and the heel may differ among different groups of people. When the user is wearing the electric power shoe 10 of this embodiment, and the rotational joint between the toes and the sole is located between the first connecting portion 111 and the second connecting portion 121 in the first direction, the elastic portion between the first connecting portion 111 and the second connecting portion 121 can also deform with the rotation of the toes relative to the sole, thereby causing the toe portion 120 and the sole portion 110 to rotate with the user's foot movements.

[0078] When different users use the electric power shoe 10 of this embodiment, or when a user uses the electric power shoe 10 of this embodiment multiple times but the position of the foot on the sole 100 is different, the elastic part between the first connecting part 111 and the second connecting part 121 can deform accordingly with the position of the rotation joint between the toes and the sole in the first direction. The position of the rotation axis of the toe part 120 relative to the sole part 110 will also be adjusted with the position of the rotation joint between the toes and the sole in the first direction, thereby causing the toe part 120 and the sole part 110 to flip with the user's foot movements.

[0079] To facilitate understanding by those skilled in the art, the following specific examples illustrate how the position of the rotation axis of the toe portion 120 relative to the foot portion 110 is adjusted according to the position of the rotation joint between the toes and the foot in the first direction. For example, when the rotation joint between the toes and the foot is located in a forward position in the first direction, the position of the rotation axis of the toe portion 120 relative to the foot portion 110 will also be located in a forward position in the first direction; conversely, when the rotation joint between the toes and the foot is located in a backward position in the first direction, the position of the rotation axis of the toe portion 120 relative to the foot portion 110 will also be located in a backward position in the first direction.

[0080] It should be noted that the elastic connection between the first connecting part 111 and the second connecting part 121 also allows the toe part 120 to rotate relative to the foot part 110 about an axis parallel to the first direction, thereby enabling the sole 100 to adapt to the user's toe eversion and inversion movements relative to the foot.

[0081] Without departing from the inventive concept of the present invention, the present invention does not limit the elastic connection method of the first connecting part 111 and the second connecting part 121. In some embodiments, the electric power shoe 10 further includes an elastic element, through which the first connecting part 111 is connected to the second connecting part 121. It should be noted that the elastic element in the above embodiments includes, but is not limited to, conventional springs, flexible hinges, etc.

[0082] As a preferred option, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 As shown, in some embodiments, the sole 100 further includes an insole 180, which is stacked above the toe portion 120 and the forefoot portion 110. The insole 180 includes an integrally connected forefoot pad 181 and a toe pad 182, which are arranged along a first direction. The insole 180 is made of an elastic material. The forefoot pad 181 is connected to a first connecting portion 111, and the toe pad 182 is connected to a second connecting portion 121, so that the toe portion 120 and the forefoot portion 110 are elastically connected.

[0083] Through the above design, the insole 180, layered above the toe section 120 and the ball of the foot 110, can support the foot. The elasticity of the insole 180 allows it to deform when pressure is applied to the foot, thus better adapting to the shape of the foot and improving the user's comfort when using the electric power shoe 10, thereby enhancing the user experience. On the other hand, the insole 180, layered above the toe section 120 and the ball of the foot 110, can adapt to the position of the rotation joint between the toes and the ball of the foot, causing the ball of the foot 110 and the toe section 120 to rotate relative to each other around different axes, so that the toe section 120 and the ball of the foot 110 rotate in accordance with the user's foot movements.

[0084] Without departing from the inventive concept of this invention, those skilled in the art can make further adjustments to the structure of the insole 180.

[0085] Please refer to Figure 6 As shown, in some embodiments, the upper surface of the insole 180 is provided with anti-slip texture. The insole 180 can increase the friction provided by the anti-slip texture, thereby reducing the slippage of the foot relative to the insole 180.

[0086] Please refer to Figure 9 As shown, for the convenience of those skilled in the art, Figure 9 The insole 180 is divided into a ball pad 181 and a toe pad 182 by a dotted line. In some embodiments, the insole 180 includes a reinforcing rib 183 extending along a first direction, located between the first connecting portion 111 and the second connecting portion 121, and connecting the toe pad 182 and the ball pad 181. With this design, the reinforcing rib 183, extending along the first direction and connecting the toe pad 182 and the ball pad 181, can enhance the rigidity of the insole 180, increase the rebound force of the toe portion 120 relative to the ball portion 110, and enhance the damping feel when the toe portion 120 rotates relative to the ball portion 110 about an axis perpendicular to the first direction.

[0087] Without departing from the inventive concept of this invention, those skilled in the art can further adjust the structure of the reinforcing rib 183. Please refer to... Figure 9 As shown, in some embodiments, the insole 180 includes two reinforcing ribs 183, which are respectively disposed on different sides of the insole 180 in a second direction, with the first direction, the second direction, and the vertical direction being perpendicular to each other. The two reinforcing ribs 183 disposed in the second direction can further enhance the rigidity of the insole 180, further enhance the rebound force of the toe portion 120 relative to the foot portion 110, which is beneficial to keep the toe portion 120 and the foot portion 110 relatively fixed when not in use, and can also enhance the damping feel when the toe portion 120 rotates relative to the foot portion 110 about an axis perpendicular to the first direction.

[0088] Please refer to Figure 9 As shown, in some embodiments, the size of the reinforcing rib 183 gradually decreases in the second direction along the first direction. Through this design, the reinforcing rib 183 can enhance the stiffness of the forward portion of the insole 180 in the first direction by a small amount, and enhance the stiffness of the rearward portion of the insole 180 in the first direction by a large amount. Because the forward portion of the insole 180 has lower stiffness in the first direction, it is more prone to bending when the user pushes off the ground, thus providing greater rebound force to the foot when lifting the foot, making it easier for the user to take a step. Because the rearward portion of the insole 180 has greater stiffness in the first direction, it is more durable and less prone to damage.

[0089] In some embodiments, the vertical dimension of the front side of the toe pad 182 in the first direction is larger than the vertical dimension of the rear side in the first direction. This design allows the toe pad 182 to have higher strength on the front side in the first direction, making it less prone to folding after long-term use and improving the durability of the toe pad 182.

[0090] Please refer to Figure 4 , Figure 10 As shown, in some embodiments, the insole 180 further includes a reinforcing sheet 184. The reinforcing sheet 184 includes a first reinforcing portion 1841 and a second reinforcing portion 1842 connected together. The second reinforcing portion 1842 is located on one side of the first reinforcing portion 1841 in a first direction. The second reinforcing portion 1842 is connected to and stacked on the toe pad 182, and the first reinforcing portion 1841 is connected to and stacked on the foot pad 181 and connected to the foot portion 110. The reinforcing sheet 184 is made of an elastic material, and its elastic coefficient is greater than that of the insole 180. Through the above solution, since the reinforcing sheet 184 is made of an elastic material and its elastic coefficient is greater than that of the insole 180, the reinforcing sheet 184 can improve the overall rigidity of the insole 180, which is beneficial for keeping the toe portion 120 and the foot portion 110 relatively fixed when not in use. It can also enhance the damping feel when the toe portion 120 rotates relative to the foot portion 110 around an axis perpendicular to the first direction.

[0091] Based on the above solution, in some embodiments, the foot pad 181 is connected to the foot portion 110 via a first reinforcing part 1841. The above solution can enhance the connection strength between the foot pad 181 and the foot portion 110, thereby making the electric power shoe 10 more robust overall.

[0092] Please refer to Figure 3As shown, in some embodiments, the electric power shoe 10 further includes a limiting member 700, which is connected to the foot portion 110 and located above the toe portion 120; the toe portion 120 is rotatable relative to the foot portion 110 to contact the limiting member 700. Through this design, the limiting member 700 can limit the rotation range of the toe portion 120 relative to the foot portion 110 by contacting the toe portion 120, which helps improve the stability of the elastic connection between the first connecting portion 111 and the second connecting portion 121 under long-term operation.

[0093] Please refer to Figure 3 As shown, in some embodiments, the electric power shoe 10 further includes a motion component 900 connected to the sole 100 and capable of driving the sole 100 to move along a first direction; the forefoot portion 110 and the toe portion 120 are in contact in the first direction. Through this solution, when the motion component 900 drives the sole 100 to move along the first direction, the forefoot portion 110 can restrict the toe portion 120 from moving in the opposite direction to the first direction, thereby ensuring that the sole 100 remains stable during movement.

[0094] Without departing from the inventive concept of this invention, those skilled in the art can make adjustments to the specific form of the motion component 900. Please refer to... Figure 1 , Figure 6 , Figure 8 As shown, in some embodiments, the motion component 900 includes multiple sets of pulleys, which are rotatably connected to the foot portion 110 and the toe portion 120 respectively, and can drive the foot portion 110 and the toe portion 120 to move along a first direction.

[0095] It should be noted that the present invention does not limit the specific connection method between the first connecting part 111 and the foot part 110, or between the second connecting part 121 and the toe part 120. The connection method can be adhesive bonding, snap-fit ​​bonding, or fixed bonding, etc.

[0096] As a preferred embodiment, in some embodiments, the first connecting part 111 is connected to the foot part 110 via secondary in-mold injection molding, and the second connecting part 121 is connected to the toe part 120 via secondary in-mold injection molding. This solution ensures secure installation while reducing the use of mounting components.

[0097] The solution utilizing the output signal of gravity sensor 300 has been described previously. Existing electric power shoes have soles divided into two parts, which rotate relative to each other via a hinge, and each part is equipped with a gravity sensor. Different gravity sensors are used to receive pressure from different positions of the user's foot and output signals to the control module of the electric power shoe based on the magnitude of the received pressure. However, these electric power shoes cannot adapt to the foot movements of different people, making it difficult for some users to control the electric power shoes by exerting force with their feet.

[0098] Through long-term practice, the inventors discovered that because the two parts of the sole of existing electric power shoes rotate relative to each other directly through mechanical hinges, and the axis of rotation for the relative rotation of the two parts is fixed, users need to align the joints between their toes and the ball of their foot with the aforementioned axis when using existing electric power shoes. Due to manufacturing limitations, electric power shoes are difficult to adapt to the foot movements of different people. When users push off the ground, their toes and the ball of their foot are prone to not fully conforming to the sole, causing the force applied by the toes and the ball of the foot to deviate from the setting position of the gravity sensor. The gravity sensor cannot receive the pressure applied by the foot, which in turn causes the output signal of the gravity sensor to differ from the actual situation. This results in the control module outputting incorrect commands to the electric power shoe, creating a risk of falling.

[0099] In view of this, please refer to Figures 1 to 11 As shown, in some embodiments, the electric power shoe 10 includes a sole 100, a base 200, and a plurality of gravity sensors 300.

[0100] Please refer to Figure 6 As shown, the sole 100 includes a ball portion 110 and a toe portion 120. The ball portion 110 supports the ball of the foot and includes a first connecting portion 111. The toe portion 120 supports the toes and includes a second connecting portion 121. The first connecting portion 111 and the second connecting portion 121 are spaced apart and elastically connected in a first direction, which is the direction from the ball portion 110 to the toe portion 120. The base 200 is located below the sole 100 and includes a first seat body 210 and a second seat body 220.

[0101] The electric power shoe 10 includes multiple gravity sensors 300, each gravity sensor 300 including a fixing part 310 and a strain part 320. At least one gravity sensor 300 is defined as a first gravity sensor 300A, and at least one gravity sensor 300 is defined as a second gravity sensor 300B. The foot part 110 is connected to the strain part 320 of the first gravity sensor 300A, and the first seat 210 is connected to the fixing part 310 of the first gravity sensor 300A. The toe part 120 is connected to the strain part 320 of the second gravity sensor 300B, and the second seat 220 is connected to the fixing part 310 of the second gravity sensor 300B.

[0102] With the above scheme, the foot part 110 is connected to the first base 210 through the first gravity sensor 300A, and the toe part 120 is connected to the second base 220 through the second gravity sensor 300B. Thus, the first gravity sensor 300A and the second gravity sensor 300B can work together to bear the pressure exerted by the user on the sole 100. Since the foot part 110 and the toe part 120 are movably connected, during the relative movement of the foot part 110 and the toe part 120, the first gravity sensor 300A and the first base 210 can move together with the foot part 110, and the second gravity sensor 300B and the second base 220 can move together with the toe part 120. The first gravity sensor 300A can receive the pressure exerted by the foot on the sole 110 and output a signal during the relative movement of the sole 110 and the toe 120. The second gravity sensor 300B can receive the pressure exerted by the foot on the toe 120 and output a signal during the relative movement of the sole 110 and the toe 120, thereby enabling the gravity sensor 300 to receive the pressure exerted by the toes and sole on the sole 100 respectively.

[0103] The foot portion 110 and the toe portion 120 are elastically connected by the first connecting portion 111 and the second connecting portion 121, allowing them to deform according to the movement of the user's foot, thus facilitating adaptation to the user's foot movements. Furthermore, since the first connecting portion 111 and the second connecting portion 121 are spaced apart and elastically connected in the first direction, the toe portion 120 can rotate relative to the foot portion 110 using the elastic portion between the first connecting portion 111 and the second connecting portion 121 as its axis of rotation, thereby adapting to the foot rotation of different individuals.

[0104] When a user pushes off the ground while wearing the electric power shoes 10 of this embodiment, the foot portion 110 can fit more closely to the user's foot, resulting in a larger force application area between the foot and the foot portion 110. This reduces the influence of the foot position on the force application position of the foot portion 110, allowing the first gravity sensor 300A connected to the foot portion 110 to collect more accurate pressure and output a more precise signal. Similarly, the toe portion 120 can fit more closely to the user's toes, also resulting in a larger force application area between the toes and the toe portion 120. This reduces the influence of the toe position on the force application position of the toe portion 120, allowing the second gravity sensor 300B connected to the toe portion 120 to collect more accurate pressure and output a more precise signal.

[0105] On the other hand, since the strain portion 320 of the gravity sensor 300 can deform relative to the fixed portion 310, when the user steps and the electric power shoe 10 contacts the ground, the gravity sensor 300 can absorb the impact on the electric power shoe 10 through its own deformation, thereby reducing the user's discomfort when stepping.

[0106] Further, please refer to Figures 6 to 11 As shown, in some embodiments, the electric power shoe 10 further includes a motion component 900, which is connected to the base 200 and used to move the base 200. Through this design, the motion component 900 can move the base 200, which in turn moves the sole 100.

[0107] Without departing from the inventive concept of this invention, those skilled in the art can adjust the structure of the motion component 900 themselves.

[0108] As a preferred option, please refer to Figure 3 , Figure 6 , Figure 8 , Figure 10 As shown, in some embodiments, the motion component 900 includes a first axle 910, a second axle 920, two first pulleys 930, and two second pulleys 940. The first axle 910 is rotatably connected to the first base 210, and the second axle 920 is rotatably connected to the second base 220. Each end of the first axle 910 is connected to a first pulley 930, and each end of the second axle 920 is connected to a second pulley 940. Through this design, the motion component 900 can move the first base 210 and the second base 220 by rotating the first pulleys 930 and the second pulleys 940.

[0109] In some embodiments, the motion component 900 further includes a motor connected to the first base 210, and the output end of the motor is driven to the first wheel axle 910. With this configuration, the motor can drive the first wheel axle 910 to rotate actively, thereby moving the electric power shoe 10.

[0110] In some embodiments, the motion component 900 includes at least two first axles 910 and four first pulleys 930; both first axles 910 are rotatably connected to the first base 210, and each end of the first axle 910 is connected to a first pulley 930. This design, by supporting the first base 210 with two sets of first pulleys 930, helps improve the stability of the electric power shoe 10.

[0111] Based on the above solution, in some embodiments, the motion component 900 further includes a transmission component, through which the two first wheel axles 910 are connected. Through this solution, the two first wheel axles 910 can move synchronously via the transmission component, which helps improve the stability of the electric power shoe 10's movement. It should be noted that the transmission component in the above embodiments can be a gear set, a timing belt, or other similar structure.

[0112] Furthermore, in some embodiments, the first seat 210 also has a receiving cavity in which the transmission assembly is housed, and the receiving cavity is used to hold lubricating oil. With the above solution, after the user drips lubricating oil into the receiving cavity, the transmission assembly can operate more stably due to the lubricating effect of the lubricating oil.

[0113] Without departing from the inventive concept of this invention, those skilled in the art can further adjust the connection structure of the wheel axle and pulley.

[0114] As a preferred option, please refer to Figure 9 , Figure 10 As shown, in some embodiments, the second wheel axle 920 includes a second shaft body 921 and two second protrusions 922. Each end of the second shaft body 921 is connected to a second protrusion 922, and the second protrusions 922 are radially protruding relative to the second shaft body 921. The second pulley 940 has a second groove 941 recessed along the axial direction of the second wheel axle 920, and the second protrusions 922 are accommodated in the second groove 941. With this design, when the second protrusions 922 located radially around the second shaft body 921 rotate about the second shaft body 921, they can push the sidewall of the second groove 941 to move, thereby assisting in driving the second pulley 940 to rotate about the second wheel axle 920.

[0115] Based on the above scheme, in some embodiments, the second protrusion 922 has a third inclined surface 9221 that is inclined relative to the axis of the second wheel shaft 920, the second groove 941 has a fourth inclined surface 9411 that is inclined relative to the axis of the second wheel shaft 920, and the second pulley 940 has a second through hole; the motion assembly 900 also includes a second connector 950, which includes a second threaded portion 951 and a second abutting portion 952. The second threaded portion 951 passes through the second through hole along the axial direction of the second wheel shaft 920. One end of the second threaded portion 951 is threadedly connected to the second pulley 940 along the axial direction of the second wheel shaft 920, and the other end is connected to the second abutting portion 952. The second abutting portion 952 abuts against the side of the second pulley 940 away from the second wheel shaft 920, and the third inclined surface 9221 abuts against the fourth inclined surface 9411.

[0116] Because the third inclined surface 9221 abuts against the fourth inclined surface 9411, when the second protrusion 922 rotates around the second wheel shaft 920, the friction generated by the third inclined surface 9221 against the fourth inclined surface 9411 can also assist in driving the second pulley 940 to rotate around the second wheel shaft 920. By rotating the second connecting member 950, the second abutting part 952 of the second connecting member 950 can drive the second pulley 940 to approach the second protrusion 922 along the axial direction of the second wheel shaft 920, thereby making the contact between the third inclined surface 9221 and the fourth inclined surface 9411 tighter, and thus improving the connection strength between the second pulley 940 and the second wheel shaft 920.

[0117] In some embodiments, the first wheel shaft 910 includes a first shaft body and two first protrusions. Each end of the first shaft body is connected to a first protrusion, and the first protrusions protrude radially relative to the first shaft body. The first pulley 930 has a first groove recessed along the axial direction of the first wheel shaft 910, and the first protrusions are accommodated in the first groove. With this design, when the first protrusion located radially around the first shaft body rotates, it can push the sidewall of the first groove to move, thereby assisting in driving the first pulley 930 to rotate around the first wheel shaft 910.

[0118] Based on the above scheme, in some embodiments, the first protrusion has a first inclined surface that is inclined relative to the axis of the first wheel shaft 910, the first groove has a second inclined surface that is inclined relative to the axis of the first wheel shaft 910, and the first pulley 930 has a first through hole; the motion assembly 900 also includes a first connector, the first connector including a first threaded portion and a first abutting portion, the first threaded portion passing through the first through hole along the axial direction of the first wheel shaft 910, one end of the first threaded portion being threadedly connected to the first pulley 930 along the axial direction of the first wheel shaft 910, and the other end being connected to the first abutting portion, the first abutting portion abutting against the side of the first pulley 930 away from the first wheel shaft 910, and the first inclined surface abutting against the second inclined surface.

[0119] Because the first inclined surface abuts against the second inclined surface, when the first protrusion rotates around the first wheel shaft 910, the friction generated between the first inclined surface and the second inclined surface can also assist in driving the first pulley 930 to rotate around the first wheel shaft 910. By rotating the first connecting member, the first abutting part of the first connecting member can drive the first pulley 930 to approach the first protrusion along the axial direction of the first wheel shaft 910, thereby making the contact between the first inclined surface and the second inclined surface tighter, and thus improving the connection strength between the first pulley 930 and the first wheel shaft 910.

[0120] Further, please refer to Figure 10 As shown, in some embodiments, the motion component 900 further includes a one-way bearing 960, which has a mounting portion 961 and a moving portion 962. The moving portion 962 is rotatably connected to the mounting portion 961, the second seat 220 is connected to the mounting portion 961, and the second wheel axle 920 is connected to the moving portion 962. The moving portion 962 can rotate unidirectionally relative to the mounting portion 961, so that the second pulley 940 can drive the second seat 220 to move in a first direction. Through the above solution, the one-way bearing 960 can limit the direction of rotation of the second pulley 940 relative to the second seat 220, prevent the second pulley 940 from rotating in the opposite direction, and improve the safety of walking.

[0121] Furthermore, in some embodiments, the first pulley 930 and the second pulley 940 are elastic. This design enables the first pulley 930 and the second pulley 940 to absorb the impact from the ground when the electric power shoe 10 contacts the ground, improving the user's foot comfort.

[0122] Further, please refer to Figure 1 , Figure 2 As shown, the electric power shoe 10 also includes a first strap 1000 and a second strap 1100. One end of the first strap 1000 is connected to one side of the base 200 in a second direction, and the other end is detachably connected to the other side of the base 200 in the second direction. One end of the second strap 1100 is connected to one side of the base 200 in the second direction, and the other end is detachably connected to the other side of the base 200 in the second direction. The second direction, the first direction, and the vertical direction are perpendicular to each other. With this design, when one end of the first strap 1000 and one end of the second strap 1100 are separated from the sole 100, the user can more easily place their foot on the sole 100. After placing the foot on the sole 100, the user can directly connect one end of the first strap 1000 and one end of the second strap 1100 to the sole 100, thereby securing the foot to the electric power shoe 10.

[0123] This invention does not limit the detachable connection form between the straps and the sole 100. In some embodiments, one end of the first strap 1000 and one end of the second strap 1100 are detachably connected to the sole 100 via a Velcro structure. This design improves the adaptability of the electric power shoe 10 to different foot shapes and allows for free adjustment of tightness. In some embodiments, one end of the first strap 1000 and one end of the second strap 1100 are both provided with magnetic snaps, and one end of the first strap 1000 and one end of the second strap 1100 are detachably connected to the sole 100 via these magnetic snaps.

[0124] It should be noted that those skilled in the art can also adjust the structure of the strap themselves. In some embodiments, the strap has a multi-layer design, with an outer layer of woven nylon or ultra-high molecular weight polyethylene webbing, an inner layer of breathable mesh material, and a surface covered with a TPU (thermoplastic polyurethane) film. In some embodiments, the edges of the strap are finished with binding or rolling to eliminate sharp edges. In some embodiments, the strap is filled with foam to improve the comfort of the user's feet.

[0125] Please refer to Figure 6As shown, in some embodiments, the electric power shoe 10 further includes a cushioning member 1200, which is elastic and connected to one side of the sole 100 in the first direction. Through this design, the cushioning member 1200 can absorb energy through its own elasticity, thereby reducing the impact on other structures of the electric power shoe 10 when it collides with an object in the first direction, and improving the durability of the electric power shoe 10.

[0126] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
