Abstract

The utility model provides an insole with a damping function. The insole comprises a body, a buffering piece, a front buffering piece and a rear buffering piece. Wherein the buffering piece, the front buffering piece and the rear buffering piece are integrally formed on the bottom surface of the body, the insole is made of a material with shock absorption and wear resistance as a basic material, the body, the buffering piece, the front buffering piece and the rear buffering piece are integrated and formed at the bottom of the insole through an integrally-formed hot-pressing process, and the body, the buffering piece, the front buffering piece and the rear buffering piece can be matched and combined in different colors. And the overall appearance of the insole is more layered. In addition, the buffer part and the balance beam are integrally designed in a 7 shape through the arc-shaped part, and collaborative optimization of foot movement supporting and stability is achieved. The arc-shaped part extends along the longitudinal arch of the foot arch and dynamically fits the shape of the foot sole during walking so as to form support; the balancing beams are arranged in the mode that the forefoot transversely extends to strengthen force exerting core areas on the two sides of the insole, the overall torsional rigidity of the forefoot is enhanced through a continuous supporting interface during steering or sudden stop or pedaling on the ground, and the lateral deviation and sliding tendency is restrained.

Description

Technical Field

[0001] This utility model relates to the field of insole structure, and in particular to an insole with shock absorption function. Background Technology

[0002] Traditional insole structures have long faced technological bottlenecks in the functional coordination between the arch and forefoot. For example, current arch support components often use homogeneous foam filling, whose geometry deviates from the natural curvature of the arch, easily causing localized pressure on the plantar fascia. Forefoot stability designs generally rely on discrete anti-slip blocks or symmetrically distributed lateral grooves, whose fragmented layout disrupts the overall transmission path of foot propulsion. During turning or sudden stops, the lack of a continuous, laterally extended support interface easily leads to forefoot grip imbalance. This deficiency exposes the core contradiction that existing technologies struggle to simultaneously address the physiological adaptation of the arch, enhanced forefoot stability, and multi-directional dynamic anti-slip properties, urgently requiring a systematic solution that integrates support and stability through structural innovation. Summary of the Invention

[0003] In view of the shortcomings mentioned above, this utility model provides an insole with shock absorption function.

[0004] The present invention adopts the following technical solution:

[0005] An insole with shock absorption function includes a body and a cushioning element. The cushioning element is embedded in the middle-forward section of the bottom of the body. The cushioning element has an integrally formed arcuate portion and a balance beam, both of which protrude from the bottom surface of the body.

[0006] The arc-shaped portion is inclinedly disposed in the middle part of the bottom of the body, and the two ends of the arc-shaped portion extend from the forefoot and heel of the middle of the body respectively, so that the arc-shaped portion corresponds to the inner longitudinal arch of the sole of the foot.

[0007] The balance beam is horizontally disposed at the front end of the bottom of the body, and extends horizontally to both sides of the body. The balance beam is connected to the end of the arc-shaped part near the forefoot, so that the balance beam corresponds to the forefoot of the foot.

[0008] In one possible implementation, the bottom surface of the buffer is textured, the texture including strip-shaped protrusions inclined relative to the body.

[0009] In one possible implementation, the insole further includes a front cushioning plate embedded in the area from the forefoot to the toes of the foot corresponding to the bottom of the body, and the front cushioning plate is spaced apart from the balance beam.

[0010] In one possible implementation, the insole further includes a rear cushioning plate embedded in the heel region of the bottom of the body, and the outer edge contour of the rear cushioning plate matches the physiological curve of the calcaneus.

[0011] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: The cushioning component of this utility model achieves synergistic optimization of foot movement support and stability through the integrated design of the arc-shaped part and the balance beam in a figure-seven shape. The arc-shaped part extends along the longitudinal arch of the foot, dynamically conforming to the shape of the sole during walking, adaptively dispersing local pressure in the arch area, and avoiding the harsh contact caused by static support structures; the balance beam, with its lateral extension layout in the forefoot, strengthens the core force-generating areas on both sides of the insole, and enhances the overall torsional stiffness of the forefoot through continuous support interfaces during turning, sudden stops, or push-off, suppressing lateral offset and slippage tendencies. Through complementary spatial configuration and functions, the two components integrate precise support for the physiological adaptation of the arch, enhanced control of multi-directional stability in the forefoot, and dynamic anti-slip requirements under complex terrain into a single cushioning system, thereby forming an integrated support and stability insole structure.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0015] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0016] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0017] The utility model discloses a shoe insole with shock absorption function, as shown in the attached... Figure 1As shown, the insole includes a body 1, a cushioning element 2, a front cushioning plate 3, and a rear cushioning plate 4, wherein the cushioning element 2, the front cushioning plate 3, and the rear cushioning plate 4 are all embedded in the bottom surface of the body 1, and the cushioning element 2, the front cushioning plate 3, and the rear cushioning plate 4 all protrude from the bottom surface of the body 1.

[0018] When the foot applies vertical pressure to the body 1, the buffer 2, the front buffer 3 and the rear buffer 4 deform under dynamic load and push back towards the upper surface of the body 1, forming a contact surface that dynamically matches the physiological curve of the foot. In this process, the impact energy is efficiently attenuated through the material's energy storage-release characteristics (such as improving the attenuation rate of running impact force), and the local hard pressure on the soft tissue of the foot caused by the rigid protrusions on the upper surface of the traditional foot (such as reducing the pressure in the arch area) is avoided, thus improving the comfort of wearing.

[0019] Preferably, the cushioning component 2, the front cushioning plate 3, and the rear cushioning plate 4 can all be integrally molded onto the bottom surface of the main body 1. Furthermore, the insole of this invention is made of a material with shock-absorbing and wear-resistant properties, such as TPU. The manufacturing process can be summarized as follows: First, a material with both shock-absorbing and wear-resistant properties is selected as the base material. The main body 1, cushioning component 2, front cushioning plate 3, and rear cushioning plate 4 are integrated into the bottom of the insole using an integral molding process. During production, differentiated patterns are first printed on the pre-defined areas corresponding to each component on the bottom of the insole to create visual distinction. Then, the areas are shaped using a hot-press molding technique. After cooling and curing, the surfaces of the cushioning component, the front cushioning plate, and the rear cushioning plate all form a three-dimensional textured surface with raised and recessed patterns. This microstructure design not only enhances the coefficient of friction between the insole and the sole to achieve anti-slip function but also improves shock absorption performance by absorbing impact through structural deformation. The final product is optimized in both functionality and aesthetics, giving the product both practicality and a sophisticated design.

[0020] Continue to refer to the appendix Figure 1 The cushioning element 2 is embedded in the middle-front section of the bottom of the main body 1, and the cushioning element 2 has an integrally formed arc-shaped part 22 and a balance beam 21. Specifically, the arc-shaped part 22 is obliquely set in the middle part of the bottom of the main body 1, and the two ends of the arc-shaped part 22 extend from the forefoot and heel of the middle of the main body 1, respectively, so that the arc-shaped part 22 corresponds to the inner longitudinal arch of the foot. At the same time, the arc-shaped part 22 extends along the physiological curve of the arch of the foot, and its curvature precisely conforms to the natural curvature of the longitudinal arch of the foot. When walking, the structure of the arc-shaped part 22 allows the insole to continuously provide support for the longitudinal arch of the foot, avoiding excessive stretching of the plantar fascia.

[0021] The balance beam 21 is located at the front end of the bottom of the main body 1 and extends to both sides of the main body 1. The balance beam 21 is laterally connected to the end of the arc-shaped part 22 near the forefoot, so that the balance beam 21 corresponds to the forefoot of the foot. When turning or walking on a slope, the balance beam 21 connects the two sides of the main body 1 to enhance the stability of the insole. The balance beam 21 and the front end of the arc-shaped part 22 form a figure-7 structure, which transmits the propulsive force when the forefoot pushes off the ground to the arc-shaped part 22 through the balance beam 21, and converts it into auxiliary power for arch rebound. This allows the cushioning and propulsion to be seamlessly connected in the gait cycle, which can form the effect of softening the landing cushioning and enhancing the power of the start.

[0022] Furthermore, the texture on the bottom surface of the cushioning element 2 includes strip-shaped protrusions inclined relative to the main body 1. These protrusions are arranged at an angle of 15°-30° towards the direction of foot propulsion, forming a directional friction-enhancing structure to prevent excessive displacement of the main body 1 and to alleviate foot pressure. Additionally, the texture pattern can match the gait propulsion path, allowing the push-off force to be converted into arch rebound kinetic energy through the figure-7 structure, thus seamlessly connecting the landing cushioning and walking propulsion processes. Preferably, the color of each protrusion can be a sequentially changing gradient to enrich the aesthetics of the insole.

[0023] Continue to refer to the appendix Figure 1 The front cushioning plate 3 is embedded in the bottom of the main body 1, corresponding to the area from the forefoot to the toes, and is spaced apart from the cushioning element 2. The front cushioning plate 3 is positioned by covering the area from the forefoot to the toes, forming a contact interface with the insole during foot propulsion. Its spaced arrangement works synergistically with the cushioning element 2, enhancing the fit between the insole and the shoe through the elastic deformation of the cushioning plate itself when the toes push off the ground, thereby improving the stability of the insole. Simultaneously, during rapid acceleration or turning, the front cushioning plate 3 generates directional friction, suppressing slippage through continuous engagement with the ground, providing locally reinforced anti-slip support for the forefoot, and meeting the friction requirements of high-intensity sports such as running and climbing.

[0024] Continue to refer to the appendix Figure 1 The rear cushioning plate 4 is embedded in the heel area at the bottom of the main body 1, and the outer contour of the rear cushioning plate 4 matches the physiological curve of the calcaneus. This positional design allows the impact force of the heel at the moment of landing to be evenly distributed across the entire contact surface of the rear cushioning plate 4, avoiding stress concentration at the heel edge of traditional insoles. At the same time, the anatomically matched structure between the calcaneus and the rear cushioning plate 4 guides the heel to naturally internally rotate during the gait rolling phase, inhibiting ankle joint displacement caused by excessive eversion. Especially when landing from running and jumping, the vertical impact is transformed into horizontal cushioning through the positionally adapted mechanical transmission path, forming a dynamic support effect.

[0025] In summary, this utility model discloses a modular shock-absorbing insole based on biomechanical design. Its core structure consists of a body 1, a cushioning component 2, a front cushioning plate 3, and a rear cushioning plate 4. The cushioning component 2, as the external shock-absorbing core, has an integrally formed arc-shaped portion 22 that precisely supports the medial longitudinal arch along the physiological curve of the foot arch. The balance beam 21 extends laterally to form a figure-7 structure, converting the forefoot push-off force into arch rebound power, achieving a seamless connection between cushioning and propulsion. The front cushioning plate 3 covers the area from the forefoot to the toes, and through its spaced layout, works synergistically with the cushioning component 2 to enhance fit and local anti-slip support during the push-off phase. The rear cushioning plate 4 matches the calcaneal curve, dispersing the impact of the ground over the entire area and guiding the heel to naturally internally rotate, inhibiting ankle joint displacement. This structure allows this utility model to match the internal space of the shoe while systematically solving the problems of displacement, support breakage, and localized high pressure in traditional insoles, achieving an upgrade in wearability for sports scenarios.

[0026] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
