[0035] The utility model provides a shoe heel structure.

[0036] As shown in Figures 1 and 2, in one embodiment of the present invention, the heel structure includes a tail portion 1 and a connecting portion 2 connected to the side of the tail portion 1. The tail portion 1 is provided with a first guide section 11 and a second guide section 12. The first guide section 11 is connected to the upper end of the second guide section 12, and a guide curved surface 110 is provided in the first guide section 11 and is tilted from bottom to top and backward. The inner side surface of the second guide section 12 is provided with a guide slope 121. The guide slope 121 is tilted relative to the guide curved surface 110. In some embodiments, the guide slope 121 can be a straight guide slope.

[0037] The technical solution of the present invention enables the user to enter the second guide section along the guide curved surface through the use of the guide curved surface of the first guide section, and the guide inclined surface of the second guide section can further accelerate the user's entry into the interior of the heel structure of the shoe, thereby improving the wearing smoothness and efficiency; and the guide inclined surface can also achieve guidance when the user takes off the shoe, thereby improving the smoothness and efficiency of taking off the shoe; in addition, by connecting the connecting part with the corresponding part of the shoe, it is possible to avoid the tail end portion from being directly connected with the corresponding part of the shoe, thereby reducing the assembly wear of the tail end portion; thereby improving the use smoothness and structural stability of the shoe heel structure.

[0038] In some embodiments, as shown in FIG1 , the tail portion 1 is U-shaped, and two connecting portions 2 are selected and connected to the ends of the U-shaped tail portion 1; the connecting portions 2 are integrally formed with the U-shaped tail portion 1. The U-shaped tail portion 1 is more stably assembled with the user's heel, and the extended connecting portions 2 prevent the U-shaped tail portion 1 from being directly assembled with the shoe, thus preventing damage to the U-shaped tail portion 1 during assembly, thereby increasing the service life of the U-shaped tail portion 1.

[0039] Specifically, in some embodiments, as shown in Figures 1 and 2, the guide slope 121 is arranged to be inclined from top to bottom and backward. An angle α is formed between the guide slope 121 and the horizontal plane of the second guide section 12. The angle α is between 60 and 90 degrees, preferably 75 degrees. This angle α ensures ease of entry and exit for the user. Furthermore, the V-shaped retaining structure formed by the guide slope 121 and the inner bottom structure of the shoe enhances foot retention and improves stability during use.

[0040] Specifically, in other embodiments, the guiding slope 121 is arranged to be tilted from top to bottom and forward; the convenience of the user's insertion is ensured by the guiding slope 121 tilted forward.

[0041] Specifically, in some embodiments, as shown in FIG2 , the guide curved surface 110 includes an arcuate section 112 and a straight section 111 tangent to the arcuate section 112; and the straight section 111 is arranged from bottom to top and tilted backward. In some embodiments, the straight section 111 forms an angle β with the horizontal plane where the first guide section 11 is located, and the angle β is 10-38 degrees, preferably 25 degrees. In some embodiments, the arcuate tangent of the arcuate section 112 forms an angle δ with the horizontal plane where the first guide section 11 is located, and the angle δ is 15-60 degrees. The user's foot is guided into the arcuate section 112 by the straight section 111 arranged from bottom to top and tilted backward, and the speed of the foot entering is increased by the arcuate smoothness of the arcuate section 112, thereby increasing the speed of wearing shoes.

[0042] Specifically, in some embodiments, as shown in Figures 1 and 4 , the heel structure further includes a reinforced outer layer 101; the reinforced outer layer 101 is connected to the back of the tail portion 1 and extends to the top of the guide curved surface 110. The reinforced outer layer 101 is constructed of an outer plate made of a material such as PVC (Polyvinyl chloride), TPU (Thermoplastic polyurethanes), or TPE (Thermoplastic Elastomer). The reinforced outer layer 101 improves the support stability of the tail portion 1, preventing excessive deformation of the first guide segment 11 during wear, thereby preventing the guide function from failing. Furthermore, the outer plate made of PVC, TPU, or TPE provides protection for the tail portion 1, preventing damage from the back.

[0043] In some embodiments, as shown in Figures 1-3, the tail portion 1 includes a first protective outer layer 103 and a first filling inner layer 102 connected to the first protective outer layer 103.

The connecting horizontal edge 21 and the connecting vertical edge 22 are arranged perpendicularly, and a retaining notch 23 is formed between the bottom of the connecting horizontal edge 21 and the side of the connecting vertical edge 22. Thus, the connecting horizontal edge 21 is retained in position on the corresponding assembly portion of the shoe, and the connecting vertical edge 22 is retained in position on another corresponding assembly portion of the shoe, thereby improving the positioning and stability of the shoe assembly.

[0045] Specifically, in some embodiments, as shown in Figures 2 and 4 , a retaining protrusion 211 is provided on the connecting horizontal edge 21. The retaining protrusion 211 is arranged to protrude inwardly from the connecting horizontal edge 21 and is located above or below the user's ankle. The retaining protrusion 211 cooperates with the connecting vertical edge 22 to provide a retaining connection to the user's foot, thereby improving wearer stability. In some embodiments, the retaining protrusion 211 abuts the lower surface of the user's ankle. When the shoe is a low-top shoe, the retaining protrusion 211 and the connecting vertical edge 22 retain the user's foot. In other embodiments, the retaining protrusion 211 abuts the upper surface of the user's ankle. When the shoe is a high-top shoe, the retaining protrusion 211 and the connecting vertical edge 22 retain the user's foot and ankle.

[0046] Specifically, in some embodiments, as shown in Figures 2 and 4, the limiting protrusion 211 is an arc-shaped limiting protrusion; the upper arc surface of the arc-shaped limiting protrusion can improve the convenience of the user putting on shoes, and the lower arc surface of the arc-shaped limiting protrusion can improve the convenience of the user taking off shoes, thereby improving the user's wearing efficiency.

[0047] Specifically, in some embodiments, as shown in Figures 1 and 4, a limiting arc surface 221 is provided on the inner side surface of the connecting vertical edge 22; the limiting arc surface 221 is used to achieve a limiting connection to the user's foot, thereby improving the user's comfort.

[0048] Specifically, in some embodiments, as shown in Figures 1 and 4 , the connecting portion 2 includes a second filling inner layer 202 and a second protective outer layer 201 connected to the second filling inner layer 202. The second filling inner layer 202 and the second protective outer layer 201 are press-fitted or integrally formed. A stopper 211 is located at the top of the second protective outer layer 201, and a stopper arc 221 is located at the bottom of the second protective outer layer 201. The second protective outer layer 201 is made of lycra fabric, and the second filling inner layer 202 is made of cotton filling.
