Abstract

The invention discloses a lifting-pin-type-mechanism-based height adjustable shoe heel driven by a shape memory alloy, and relates to the technical field of high-heeled shoes. The shoe heel comprises a lifting pin type mechanism, a shoe sole, a shape memory alloy spring, a power supply, a controller and an extension spring. The lifting pin type mechanism is connected with the shoe sole, located below the shoe sole and comprises an inner shoe heel body, an external shoe heel body and a rigid guide rod. A blind hole is formed in the external shoe heel body, and the inner shoe heel body is located in the blind hole formed in the external shoe heel body. The inner shoe heel body can be move upwards and downwards relative to the external shoe heel body. One end of the rigid guide rod is arranged on the inner wall of the blind hole of the external shoe heel body, and the other end of the rigid guide rod is arranged in a hole formed in the outer wall of the inner shoe heel body. The extension spring and the shape memory alloy spring are arranged between the inner shoe heel body and the external shoe heel body. The shape memory alloy spring is connected with the controller through a wire. The controller is connected with the power supply and comprises a wireless receiver and a wireless switch which are connected in series. According to the shoe heel, the shape memory alloy spring is heated with electricity to drive the lifting pin type mechanism so as to make the height of the shoe heel changed.

Description

technical field [0001] The invention relates to the technical field of high-heeled shoes, in particular to a height-adjustable shoe heel driven by a shape memory alloy and based on a push pin mechanism. Background technique [0002] At present, high heels have become an important part of women's life. Many women like to wear high-heeled shoes. High-heeled shoes can elongate a woman's body shape, highlight her body line, and enhance her overall temperament. However, the heel heights of existing high-heeled shoes are mostly fixed and non-adjustable, which cannot meet the different requirements of high-heeled shoes users on different occasions to the heel height. For example, in public places, women need higher heels in order to appear relatively tall and conspicuous, and when driving, wearing high heels with higher heels may cause traffic accidents. At present, there are many patents on the technology of high-heeled shoes with adjustable heel height, but there are still many...
