TECHNICAL FIELD

[0001] The utility model relates to the field of shoe material accessories, especially to a shockproof mute top skin for upper and lower differentiation effect of shoe heel. BACKGROUND

[0002] The heel is one of the main stress points when walking, and it is the part that wears out quickly at the bottom of the shoe, and it plays a key role in comfort. Therefore, the existing shoe heel is equipped with an auxiliary accessory, namely the top skin, which is in contact with the ground, and the general English name is Toplift or Toppiece;

[0003] The top skin of the shoe heel at present is mainly made of rubber or other high-hardness elastomer materials, which cannot take into account the characteristics of anti-skid, shockproof, mute, high wear resistance and visual effect of appearance, and cannot meet the increasingly high standards of the current consumer market;

[0004] And the existing double-hardness top skin, such as the public number: CN119423451B, in the disclosed technical solution, the soft elastomer is formed by injection molding and completely covers the side wall and bottom surface of the hard support body. This full covering structure can avoid the falling off and cracking of the joint between the two materials, but it also makes the exposed surface of the top skin only present the single form and texture of the soft elastomer. At present, consumers not only pay attention to comfort, but also pursue fashion design such as material splicing, color matching and texture contrast in the shoe market. The single soft appearance will make the top skin lack visual level and recognition in vision, and it is difficult to adapt to the appearance requirements of high-end shoes or personalized shoes.

[0017] The utility model will be further described below in combination with drawings and specific examples, but example does not make any form to the utility model with limitation.

[0018] As shown in the figure: Figures 1-4

[0019] A kind of shock-absorbing mute upper leather for upper and lower differentiation effect of shoe heel, it is characterized in that, including hard support body 100 and soft elastomer 200.Using hard support body matrix ensures that shoe heel assembly is anti-falling and structurally stable, while through soft elastomer outer layer gives landing layer high skid resistance, shock resistance, mute and high wear resistance and other dynamic performance.

[0020] The hard support body 100 assembly end surface has several connecting columns 110 for being connected with shoe heel, and the connecting column 110 is used for upper leather and shoe heel bottom connection fixed, and the connecting column 110 is integrally injection molded with the hard support body 100.

[0021] ​The surface of the hard support body 100 at least partially in contact with the soft elastomer 200 has a plurality of through holes 120. The purpose of providing the through holes 120 in the hard support body 100 is to facilitate the injection of the injection material into the through holes 120 during the injection molding of the soft elastomer 200. After cooling, the soft elastomer 200 is formed and integrated with the hard support body 100. By providing the through holes 120, the contact area of the soft elastomer 200 and the hard support body 100 is increased, and the integration effect and the firmness after integration are improved.

[0022] The through holes 120 at one end surface of the hard support body 100 provided with the connecting column 110 have a larger hole diameter than the through holes 120 at the other end surface. The through holes 120 are stepped holes or tapered holes. In this embodiment, stepped holes with a larger hole diameter at the top and a smaller hole diameter at the bottom are used. The purpose of using stepped holes or tapered holes is to further improve the integration firmness of the soft elastomer 200 and the hard support body 100. Even if grease or other contaminants enter during the injection molding process, the integration degree of the soft elastomer 200 and the hard support body 100 will not be high, and the soft elastomer 200 and the hard support body 100 will not directly delaminate and separate.

[0023] The bottom edge of the hard support body 100 is provided with a continuous upward extending fixed surrounding edge 130. The fixed surrounding edge 130 is circumferentially arranged around the bottom surface and is used for embedding the edge portion of the soft elastomer 200 to achieve limiting. The height of the fixed surrounding edge 130 is 1mm to 9mm, and the preferred height is 3mm. The soft elastomer 200 extends upward from the bottom surface of the hard support body 100, and the top surface height is higher than the top surface height of the fixed surrounding edge 130, with an overheight of 1.5mm to 10mm, and the preferred overheight is 8mm. The inner wall of the fixed surrounding edge 130 is inclined inward, further enhancing the stability of the skin. The inner wall of the fixed surrounding edge 130 is provided with a plurality of anti-extraction ribs 131. The cross section of the anti-extraction rib 131 is semicircular or quadrilateral. The anti-extraction rib 131 is embedded in the soft elastomer to form a limiting position, preventing the soft elastomer 200 from rotating or laterally deviating during use, and further improving the stability of the integrated structure.

[0024] The soft elastomer 200 is injection molded to cover the bottom surface of the hard support body 100, with the edge portion embedded in the fixed surrounding edge 130 and interpenetratingly engaged with the hard support body 100 to form an integrated structure. This design allows the soft elastomer to be partially embedded in the fixed surrounding edge 130, avoiding the skin exposed surface showing only a single form of soft elastomer. By local exposure, material splicing, color clashing or texture contrast is achieved, giving the skin rich visual levels.

[0025] The rigid support 100 is made of a material with a Shore hardness of 85A (or Shore hardness of 60D) or higher. The available materials are rubber and plastic materials or composite modified materials. The preferred materials are CPU, TPU, carbon fiber, PA, PA composite carbon fiber and TPU composite PA. Because the rigid support 100 plays the role of supporting and connecting the heel, its material must have both a certain toughness to resist impact and the hardness to provide support.

[0026] The injection molding temperature of the rigid support 100 is between 170 degrees Celsius and 280 degrees Celsius. In this embodiment, the injection molding temperature is preferably 215 degrees Celsius.

[0027] The soft elastomer 200 is made of a rubber-plastic elastomer material with a Shore hardness of 78A to 40A, preferably TPU.

[0028] Because the soft elastomer 200 needs to meet the requirements of anti-slip, noise reduction, and wear resistance, it is made of a soft elastic material with low hardness and high wear resistance.

[0029] The injection molding temperature of the soft elastomer 200 is between 150 degrees Celsius and 185 degrees Celsius, and the injection molding temperature in step two is preferably 185 degrees Celsius.

[0030] The TPU material in this embodiment is thermoplastic polyurethane elastomer rubber, which is an environmentally friendly new elastomer material.
