Detailed implementation manners

[0041] To further explain the technical solution of the present utility model, the following will be elaborated in detail through specific embodiments.

[0042] A heel cup of the present utility model, as Figures 1 - 18As shown, it includes a heel cup body connected to the sole 2 and supporting the heel surface layer 3; the heel cup body includes a receiving and supporting portion 11 at the lower part for receiving the human heel 4 and an elastic swinging support plate 12 at the upper part that can elastically swing towards the outside of the shoe. The receiving and supporting portion 11 has a receiving space 111 for receiving the human heel 4. In the actual use process of the present utility model, when the user wears shoes, the human toe extends into the shoe from the shoe opening, and the human heel 4 contacts the elastic swinging support plate 12. When the heel presses on the elastic swinging support plate 12, the elastic swinging support plate 12 elastically swings towards the outside of the shoe by relying on its elasticity, making the shoe opening expand outwards and the inclination of the part in contact with the heel gradually increase, and performing a guiding similar to a shoehorn to push the heel forward and guide it downwards. The heel smoothly enters the shoe. As the user's toe gradually extends into the shoe, the elastic swinging support plate 12 dodges the heel and allows the heel to enter the shoe. As the heel enters the shoe and no longer presses outwards on the elastic swinging support plate 12, the elastic swinging support plate 12 elastically swings back towards the inside of the shoe by relying on its elasticity and blocks above the heel, making the heel be placed at the receiving and supporting portion 11 of the heel cup, realizing a stepping-on shoe wearing action without assistance, and the whole shoe wearing process is smooth and efficient; moreover, the elastic swinging support plate 12 that swings back towards the inside of the shoe can relieve pressure on the upper part of the heel, ensuring that the heel is not easily taken out of the shoe while having a certain auxiliary buffering performance. The upper elastic swinging support plate 12 does not affect the strength of the lower receiving and supporting portion 11, overall ensuring the strength and movement performance of the heel cup. Only when the heel applies enough pulling force relative to the shoe can it cross the elastic swinging support plate 12 and be taken out from the receiving and supporting portion 11 and the shoe. The elastic swinging support plate 12 can be connected to the receiving and supporting portion 11 through at least one of the upper, lower, left, and right parts. The preferred specific structure can be that the elastic swinging support plate 12 has a connecting end 121 at the upper end connected to the receiving and supporting portion 11 and a free swinging end 122 at the lower end that can freely swing towards the outside of the shoe.That is, the free swing end 122 at the lower end of the elastic swing support plate 12 is suspended, and can swing toward the outside and inside of the shoe by relying on the connection end 121 at the upper end of the elastic swing support plate 12. In particular, when the human heel 4 is forced by the inner surface (the surface facing the inside of the shoe) of the elastic swing support plate 12, the elastic swing support plate 12 will be squeezed to swing toward the outside of the shoe by relying on the connection end 121. Since the pedaling force of the human heel 4 drives the elastic swing support plate 12 to swing toward the outside of the shoe, the human heel 4 will smoothly enter the accommodating support portion 11 in the shoe. When the human foot tends to slip out of the accommodating support portion 11, the human heel 4 will be pushed into the accommodating support portion 11. When the heel 4 is stepped on, the elastic swing support plate 12 will provide downward support and resistance to the heel 4 of the human body. Only a small part of the upward pulling force of the heel is applied to the outside of the shoe, and it will be offset by the force that drives the elastic swing support plate 12 upward to swing into the shoe. Therefore, the heel 4 of the human body is not easy to escape upward from the accommodating support portion 11. This situation will be particularly obvious when at least the upper part of the elastic swing support plate 12 gradually tilts from top to bottom toward the inside of the shoe, which not only enhances the sensitivity of the elastic swing support plate 12 to deformation and swinging under the pedaling, but also supports and resists the heel 4 of the human body from escaping upward, ensuring the wrapping and exercise strength of the heel 4 of the human body. In practice, it is preferred that the elastic swing support plate 12 gradually tilts from top to bottom toward the inside of the shoe, and the elastic swing support plate 12 gradually bends downward from top to bottom, so that the heel 4 of the human body can be more efficiently guided into the shoe, and the curved elastic swing support plate 12 is more friendly to the heel 4 of the human body and comfortable to wear. The angle between the elastic swing support plate 12 and the horizontal plane is 10-80°, preferably 25-60°, and specifically 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70 and 75°. If the heel cup is overall high, the angle can be selected to be a larger angle such as 45-80°. If the heel cup is overall short, the angle can be selected to be a smaller angle such as 10-45°. The accommodating support portion 11 is a wall structure surrounding the human heel 4 and forming an accommodating space 111 to ensure the overall strength and support performance of the heel cup. The heel cup body can be specifically made of materials with certain strength and toughness such as TPU, PU, ​​TPE, PE, PC or nylon. The accommodating support portion 11 is provided with decorative holes or the outer surface is covered with a decorative layer. The decorative holes can be specifically a plurality of decorative holes forming a mesh distribution. The decorative layer can be specifically a coating or other attached decorative material layer. In order to facilitate the connection between the heel cup and the sole 2 or the heel surface layer 3, the lower end of the heel cup body is provided with two or more extension connectors connected to the sole 2. The extension connectors have the function of shaping the lower edge of the heel cup body, so as to facilitate the connection with the sole 2 or the heel surface layer 3 by gluing or sewing. The extension connectors can extend downward or forward. The specific structure can be that the thickness of the edge of the heel cup body is thinner than the thickness of the inner area of ​​the edge, which is convenient for connecting with the edge of the heel surface layer 3.

[0043] In order to make the elastic swing support plate 12 swing inward and outward more smoothly, it is further preferred thatFigures 1 - 14 As shown, a receiving opening 13 for receiving the elastic swing support plate 12 is formed in the heel cup body. This structure can ensure that the elastic swing support plate 12 is not blocked or restricted in the front and rear directions of swinging, ensuring the smooth and gentle performance of the elastic swing support plate 12 during internal and external swinging. At the same time, it simplifies the thickness of the heel cup and can also ensure the smooth demolding, swinging toughness, and strength of the integral injection molding of the elastic swing support plate 12 and the heel cup body. The specific structure can be that the upper end of the elastic swing support plate 12 is connected to the upper edge of the receiving opening 13, and there is a lower gap 131 between the lower end of the elastic swing support plate 12 and the lower edge of the receiving opening 13, and there are side gaps 132 between the two sides of the elastic swing support plate 12 and the side edges of the receiving opening 13. The lower gap 131 is connected to the side gaps 132 on both sides. The connected lower gap 131 and the side gaps 132 on both sides enable the elastic swing support plate 12 to swing except for the upper end, with only the upper end as the fulcrum. When the elastic swing support plate 12 is subjected to forces such as stepping, there is a large enough lever arm for the elastic swing support plate 12 to swing relying on the upper end fulcrum. Moreover, the lower gap 131 and the side gaps 132 on both sides can further ensure that the elastic swing support plate 12 is not scratched or restricted in the front and rear directions of swinging, ensuring the smooth and gentle performance of the elastic swing support plate 12 during internal and external swinging, and can also ensure the smooth demolding during the integral injection molding of the elastic swing support plate 12 and the heel cup body. The specific structure can be that the lower gap 131 and the side gaps 132 on both sides of the elastic swing support plate 12 form a U shape, ensuring that except for the upper end, the entire lower part of the elastic swing support plate 12 is in a state of being able to swing freely inside and outside relying on the upper end on the basis of stable and firm structure.

[0044] Further preferably, the upper part of the heel cup body has an inclined portion 15 which gradually extends from bottom to top toward the outside of the shoe; the upper end of the elastic swing support plate 12 is connected to the lower end of the inclined portion 15, and at least the upper part of the elastic swing support plate 12 gradually tilts from top to bottom toward the inside of the shoe; both sides of the inclined portion 15 have connecting support portions 151 connected to the accommodating support portion 11; the elastic swing support plate 12 is located between the two connecting support portions 151, and the lower end of the inclined portion 15 constitutes the upper edge of the accommodating opening 13, and the two connecting support portions 151 constitute the two side edges of the accommodating opening 13. The upper end of the elastic swing support plate 12 is connected and restricted, and the entire elastic swing support plate 12, especially the lower end, relies on the upper end to swing toward the outside and inside of the shoe. When the user wears the shoe, the toes extend obliquely downward into the shoe opening and the heel tilts obliquely upward. The human heel 4 may first step on the inclined portion 15 or directly step on the elastic swing support plate 12. The inclined portion 15 gradually extending obliquely toward the outside of the shoe from bottom to top and at least the upper portion of the elastic swing support plate 12 gradually tilting toward the inside of the shoe from top to bottom can adapt to the inclination of the sole of the human heel 4, and provide a comfortable and friendly contact with the human heel 4. The stepping force of the human heel 4 will drive the elastic swing support plate 12 to swing downward and toward the outside of the shoe, adapting to and avoiding the human heel 4, and the elastic swing support plate 12 plays a role in guiding the human heel 4 into the shoe; when the human heel 4 is against the elastic swing support plate 12 When the movable support plate 12 applies a stepping force downward, the human heel 4 will squeeze the elastic swing support plate 12 and swing downward and outward from the shoe by relying on the upper end as a deformation fulcrum, and the human heel 4 will smoothly enter the accommodating support portion 11 in the shoe; and when the human foot has a tendency to slip out of the accommodating support portion 11, at least the upper portion of the elastic swing support plate 12 gradually tilted from top to bottom toward the inside of the shoe will provide downward and inward support resistance to the human heel 4, and the human heel 4 is not easy to slip out upward from the accommodating support portion 11. At least the upper portion of the elastic swing support plate 12 gradually tilted from top to bottom toward the inside of the shoe can enhance the sensitivity of the elastic swing support plate 12 to deformation and swinging under the pedaling, and can also support and resist the human heel 4 from slipping out upward, ensuring the smoothness, efficiency, comfort, and wrapping and movement performance of the human heel 4 when wearing the shoe. The connecting support portion 151 supports the inclined portion 15 and the entire elastic swing support plate 12, and maintains the entire upper shape and structural strength of the heel cup body. The angle between the inclined portion 15 and the elastic swing support plate 12 and the horizontal plane is 10-80°, specifically 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70 and 75°. In order to ensure the structural strength of the connecting support portion 151, the specific structure may be that the thickness of the connecting support portion 151 is greater than the thickness of the accommodating support portion 11, or the connecting support portion 151 has a reinforcing rib, which may be specifically arranged on the outer side of the connecting support portion 151.In practice, it is preferred that the upper portion of the elastic swing support plate 12 bends gradually downward from top to bottom, while the lower portion bends gradually toward the outside of the shoe from top to bottom. This can more efficiently and comfortably guide the human heel 4 into the shoe, while the lower portion of the elastic swing support plate 12 bent toward the outside of the shoe adapts to the curvature of the human heel 4, making more friendly contact with the human heel 4 and making it comfortable to wear. In order to ensure the connection strength and deformation toughness between the elastic swing support plate 12 and the heel cup body, the specific structure can be that the elastic swing support plate 12 and the heel cup body are integrally formed, preferably by integral injection molding of a polymer material, such as TPU, PU, ​​TPE, PE, PC or nylon, etc., which has a certain elasticity and toughness strength; in order to avoid the human heel 4 from hitting the lower edge of the accommodating opening 13 when stepping into the accommodating support portion 11, the lower edge of the accommodating opening 13 is closer to the outside of the shoe than the lower edge of the elastic swing support plate 12, so that the lower edge of the accommodating opening 13 avoids the human heel 4 stepped downward, ensuring that the process of the elastic swing support plate 12 guiding the human heel 4 into the shoe is smoother and more comfortable. The specific structure can be that the lower edge of the accommodating opening 13 has an inclined edge extending gradually backward from bottom to top, or the inner side of the lower edge of the accommodating opening 13 has an inclined surface gradually inclined backward from bottom to top. This structure can further ensure that the lower edge of the accommodating opening 13 avoids the human heel 4 stepped downward, ensuring The elastic swing support plate 12 makes the process of guiding the human heel 4 into the shoe smoother and more comfortable; the lower edge of the accommodating opening 13 can specifically extend upward to a position that is equal to or nearly equal to the lower edge of the elastic swing support plate 12, thereby ensuring the strength of the accommodating support portion 11 and the entire heel cup; at least one of the elastic swing support plate 12 and the connecting support portion 151 has an elastic deformation portion 16 with stress concentration at the upper portion, and the elastic deformation portion 16 ensures the elastic swing performance of the elastic swing support plate 12 toward the outside and inside of the shoe, that is, when the human heel 4 applies a downward stepping force to the elastic swing support plate 12, the human heel 4 will squeeze the elastic swing support plate 12 and swing downward and toward the outside of the shoe by relying on the elastic deformation portion 16 as an elastic deformation fulcrum. As the heel enters the shoe, the elastic swing support plate 12 is no longer pressed outward, and the elastic swing support plate 12 relies on the elastic deformation portion 16 as an elastic deformation fulcrum to swing back toward the inside of the shoe and block the heel, so that the heel is accommodated in the accommodating support portion 11 of the heel cup. The specific structure may be that the elastic deformation portion 16 is in the shape of a flat plate, which is conducive to elastic deformation.

[0045] Preferably, the elastic swing support plate 12 protrudes further into the shoe than the accommodating support portion 11. This structure can ensure that the elastic swing support plate 12 that swings back into the shoe after the human heel 4 steps into the accommodating support portion 11 can be pressed gently on the upper part of the heel, ensuring that the heel is not easy to fall out of the shoe, and at the same time, it has a certain auxiliary buffering performance; the elastic swing support plate 12 gradually extends from top to bottom into the shoe, and the elastic swing support plate 12 gradually bends downward from top to bottom, which can more efficiently and comfortably guide the human heel 4 into the shoe; the elastic swing support plate 12 The shoe further comprises a lower curved portion 123 at the lower end, which gradually extends outward from top to bottom. When the human heel 4 steps into the accommodating support portion 11, the gradually outwardly curved portion 123 can adapt to the curvature of the human heel 4, making a more friendly contact with the human heel 4 and providing comfort when wearing. When the human foot has a tendency to slip out of the accommodating support portion 11, the force applied by the heel to the elastic swing support plate 12 is upward, which makes it difficult for the elastic swing support plate 12 to swing outward, thereby preventing the human heel 4 from slipping out of the accommodating support portion 11 and the shoe. The specific structure can be that the elastic swing support plate 12 has a protruding portion 124 facing the inside of the shoe, and the projection of the protruding portion 124 on the horizontal plane is an arc that is adapted to the curvature of the human heel 4. When the human heel 4 is gradually introduced into the shoe along the elastic swing support plate 12, the arc-shaped protruding portion 124 can adapt to the shape of the human heel 4 and contact in the form of a surface, making the wearing feeling more comfortable and friendly. Moreover, when the human heel 4 steps into the accommodating support portion 11, the elastic swing support plate 12 that returns to swing into the shoe can comfortably and slowly press on the upper part of the heel through the arc-shaped protruding portion 124, ensuring that the heel is not easy to fall out of the shoe, while also having certain auxiliary buffering performance to ensure wearing comfort; the elastic swing support plate 12 is located behind the human heel 4 or on the side of the human heel 4. Regardless of whether the elastic swing support plate 12 is located behind or on the side of the human heel 4, the above-mentioned effects of convenient shoe wearing and comfortable foot feel can be achieved. When the elastic swing support plate 12 is behind the human heel 4, the elastic swing support plate 12 can swing elastically forward and backward to directly guide the rear end of the human heel 4. When the elastic swing support plate 12 is on the side of the human heel 4, the specific structure can be that the two sides of the heel cup body have extended support parts extending toward the front of the shoe to the two sides of the human heel 4; the extended support parts are provided with side elastic swing support plates that can swing elastically toward the side of the shoe, and the side elastic swing support plates can swing elastically left and right to directly guide the side of the human heel 4. At least one of the inner surface and the outer surface of the elastic swing support plate 12 is provided with an elastic buffer pad 17.The elastic cushion 17 provided on the inner surface of the elastic swing support plate 12 is used for gentle and friendly contact with the human heel 4 to ensure comfort; the elastic cushion 17 provided on the outer surface of the elastic swing support plate 12 is used for elastic cushion support on the outer side of the elastic swing support plate 12 to maintain the working position of the elastic swing support plate 12, and to prevent the elastic swing support plate 12 from being directly in contact with the shoe heel surface layer 3 and being restricted, which affects the elastic swing of the elastic swing support plate 12. Moreover, the thickness of the elastic cushion 17 provided on the outer surface of the elastic swing support plate 12 can be adjusted according to actual design requirements to achieve the aesthetic appearance design of different arcs on the outer side of the shoe heel. The elastic cushion 17 can specifically be fabric, sponge or other foaming materials with a certain softness.

[0046] Another preferred embodiment is as Figure 15 shown. The heel cup body includes a support plate portion 14 connected to the upper end of the accommodation support portion 11 and extending upward. The upper end of the elastic swing support plate 12 is connected to the lower end of the support plate portion 14. Both the elastic swing support plate 12 and the support plate portion 14 gradually extend obliquely outward from bottom to top. That is, the heel cup body does not accommodate the elastic swing support plate 12 through the accommodation opening 13, but the elastic swing support plate 12 is directly located inside the heel cup body. Compared with the technical solution of accommodating the elastic swing support plate 12 through the accommodation opening 13, on the basis of having the above effect of guiding the human heel 4 into the accommodation support portion 11 smoothly, only the thickness of the heel cup is increased on the inner side of the original thickness, but the overall strength of the heel cup will be higher, which is suitable for shoes with strict high requirements for the strength of the heel cup.

[0047] Another preferred embodiment is as Figures 16 - 18 shown. The heel cup body includes a support plate portion 14 connected to the upper end of the accommodation support portion 11 and extending upward. The upper end of the elastic swing support plate 12 is connected to the upper end of the support plate portion 14. Both the elastic swing support plate 12 and the support plate portion 14 gradually extend obliquely outward from bottom to top. That is, the heel cup body does not accommodate the elastic swing support plate 12 through the accommodation opening 13, nor does it directly extend from the lower end of the support plate portion 14. Instead, the elastic swing support plate 12 is connected from the upper end of the support plate portion 14 and then winds down from the inner surface of the support plate portion 14 and is directly located inside the heel cup body. Compared with the technical solution of accommodating the elastic swing support plate 12 through the accommodation opening 13, on the basis of having the above effect of guiding the human heel 4 into the accommodation support portion 11 smoothly, only the thickness of the heel cup is increased on the inner side of the original thickness, but the overall strength of the heel cup will be higher, which is suitable for shoes with strict high requirements for the strength of the heel cup. To facilitate the free backward swing of the elastic swing support plate 12, as Figure 18As shown, the specific structure may be that there is a swing gap between the elastic swing support plate 12 and the support plate part 14 for the elastic swing support plate 12 to swing backward; or, the support plate part 14 is formed with a window 141 corresponding to the rear of the elastic swing support plate 12, and this window 141 provides a space for the elastic swing support plate 12 to swing backward and facilitates the demolding of the elastic swing support plate 12 from the rear to a certain extent.

[0048] A shoe made based on the aforementioned heel cup, such as Figures 1 - 18 As shown, it further includes a sole 2 and a shoe heel surface layer 3 connected to the heel cup. The shoe heel surface layer 3 has an inner surface facing the inside of the shoe and an outer surface facing the outside of the shoe; the elastic swing support plate 12 has an inner surface facing the inside of the shoe, and an elastic buffer pad 17 is provided on the inner surface of the plate. In the actual use process of the present invention, the heel cup is installed at the shoe heel to support the shoe heel surface layer 3, and the elastic buffer pad 17 protrudes towards the inside of the shoe. When the user wears the shoes, the human toe extends into the shoe from the shoe opening, and the human heel 4 gently and friendly contacts with the elastic buffer pad 17 of the elastic swing support plate 12. When the heel presses on the elastic buffer pad 17, the elastic swing support plate 12 drives the elastic buffer pad 17 to elastically swing towards the outside of the shoe by relying on elasticity, causing the shoe opening to open outwards and the inclination of the part in contact with the heel to gradually increase, and performing a guiding similar to a shoehorn to push the heel forward and guide it downward. The heel smoothly enters the shoe. As the user's toe gradually extends into the shoe, the elastic swing support plate 12 drives the elastic buffer pad 17 to avoid the heel and allows the heel to enter the shoe. As the heel enters the shoe and no longer presses on the elastic swing support plate 12 outward, the elastic swing support plate 12 drives the elastic buffer pad 17 to swing back towards the inside of the shoe by relying on elasticity and blocks above the heel. The elastic buffer pad 17 gently and friendly contacts with the upper part of the human heel 4, enabling the heel to be placed in the accommodation support part 11 of the heel cup, realizing the stepping-on shoe-wearing action without assistance, and the whole shoe-wearing process is smooth and efficient; moreover, the elastic swing support plate 12 and the elastic buffer pad 17 that swing back towards the inside of the shoe can relieve pressure on the upper part of the heel, ensuring comfort while also ensuring that the heel is not easily detached from the shoe, and having a certain auxiliary buffering performance. The upper elastic swing support plate 12 does not affect the strength of the lower accommodation support part 11, and overall ensures the strength and movement performance of the heel cup. Only when the heel applies sufficient pulling force relative to the shoe can it cross the elastic swing support plate 12 and the elastic buffer pad 17 and be detached from the accommodation support part 11 and the inside of the shoe. The specific structure may be that an elastic buffer pad 17 is also provided on the outer surface of the elastic swing support plate 12. The elastic buffer pad 17 provided on the outer surface of the elastic swing support plate 12 is used for elastic buffer support on the outside of the elastic swing support plate 12, maintaining the working position, and avoiding the elastic swing support plate 12 being directly in contact with the shoe heel surface layer 3 and being restricted, affecting the elastic swing of the elastic swing support plate 12. The elastic buffer pad 17 may specifically be a fabric, sponge or other foaming materials with a certain softness.

[0049] Regarding the setting position of the heel cup, in one specific embodiment, as Figure 7 shown, the heel cup body is provided on the inner surface of the shoe upper; on the basis that this structure can directly contact the human heel 4 with the heel cup and bring into play the above advantages such as efficient and smooth shoe wearing, the shoe heel upper layer 3 can also be used as a decorative layer of the shoe heel for aesthetic design.

[0050] In another specific embodiment, as Figure 8 shown, the heel cup body is provided on the outer surface of the shoe upper; this structure can make the heel cup serve as the exoskeleton of the shoe heel upper layer 3, directly contact the human heel 4 through the soft shoe heel upper layer 3, and is more comfortable and friendly on the basis of bringing into play the above advantages such as efficient and smooth shoe wearing.

[0051] In still another specific embodiment, as Figure 9 and 12 shown in FIGS. 13-14, the shoe heel upper layer 3 includes an inner layer 31 close to the inside of the shoe and an outer layer 32 close to the outside of the shoe, and the heel cup body is provided between the inner layer 31 and the outer layer 32. This structure can make the heel cup serve as the endoskeleton of the shoe heel upper layer 3, directly contact the human heel 4 through the soft inner layer 31, and on the basis of using the outer layer 32 as a decorative layer of the shoe heel for aesthetic design, also bring into play the above advantages such as efficient and smooth shoe wearing.

[0052] The product form of the present utility model is not limited to the illustrations and embodiments in this case. Any person who makes appropriate changes or modifications with a similar idea shall be regarded as not departing from the patent scope of the present utility model.
