Description

Technical Field

[0001] The present invention belongs to the field of measuring instruments, and particularly relates to a foot shape measuring instrument based on subjective perception. Background Art

[0002] In recent years, the demand for personalization and comfort in the field of shoes has been continuously increasing. Especially, people's attention to health has put forward higher requirements for the comfort of shoes. However, there are problems such as unclear information of shoe products on the market and consumers' unclear understanding of their own foot shapes. It takes time and effort to find a pair of shoes that fit oneself. The customized shoes and boots come into being. Traditional foot shape measurement uses traditional tools such as measuring tapes or obtains foot shape data through three-dimensional reconstruction from optical photos. However, these methods obtain characteristic data under the guidance of external factors. Essentially, shoe production is still based on characteristic parameters, without obtaining subjective sensory data and unable to reflect the requirements of consumers' personal wearing habits for shoes. Summary of the Invention

Detailed Description of the Invention

[0015] The present invention will be described in detail below in conjunction with the specific embodiments.

[0016] As Figure 1 shown, the present invention discloses a foot shape measuring instrument based on subjective perception, including an external housing 1 and an internal housing 2. The external of the internal housing 2 is provided with a battery and motor module 7, and the inner wall is provided with a plurality of test units. The test units include an external airbag 5, an internal airbag 6, an air pump 3, and an air duct 4. The inner side of the external airbag 5 is provided with an internal airbag 6 and a microprocessor. The external airbag 5 and the internal airbag 6 are connected through a valve air duct. The inner layer of the internal airbag 6 is provided with a sensor group. The air pump 3 is arranged in the cavity formed by the external housing 1 and the internal housing 2 and is connected to the external airbag 5 through the air duct 4.

[0017] The external airbag is made of flexible airtight material and is connected to the air pump through the main air duct. When looking for more comfortable shoes and boots, when the subjective feeling is comfortable inside the tester cavity, each main airbag at the foot shape characteristic part is inflated to wrap the foot shape characteristic part, and then the internal airbag is inflated through the air duct for fine adjustment. When the pressure sensor covered on the internal airbag reaches the contact range, an electric current will be generated to activate the internal circuit. The light emitting device and the light sensor in each independent test module are activated. The strength of the optical signal and the magnitude of the pressure in the break point flexible material wrapped outside the optical fiber can be used as an index to judge the bending degree of the characteristic position. The signals collected by the signal collector are transmitted to the computer and software through data for analysis.

[0018] AsFigure 2 As shown, the sensor group includes a pressure sensor, a pressure coating, a break-point optical fiber, and an optical sensor. The pressure coating 13 is connected to the pressure sensor 9 via a wire. A light-emitting unit and an optical sensor 10 are provided at the end of the optical fiber 11, and the surface of the optical fiber 11 and the optical sensor is covered with a break-point flexible material 12.

[0019] As Figure 3 shown, a charging port 15 and a data transmission port 15 are provided on the outside of the outer housing 1.

[0020] In the test, the outer housing 1 is located on the outermost side, and an air pump 3 and part of the air passage 4 are provided inside. The outer housing 1 and the inner housing 2 are fixed by screws. Six test units, namely, toe-metatarsal circumference, right foot, left foot, dorsal surface, sole, and heel, are provided inside the inner housing. Each test unit contains an outer airbag 5 and an inner airbag 6 connected to the air pump 3 via the air passage 4. By adjusting the inflation amount in the different air passages 4, the pressure of the inner airbag on the foot can be adjusted, so as to find the most comfortable pressure value.

[0021] A storage battery and a motor 7 are provided outside the test unit for power supply. A pressure coating 13 is provided on the surface of the inner airbag 6, which can sense the applied pressure value. An optical fiber 11 is provided at the rear of the pressure coating. When the foot contacts the pressure coating 13, the pressure sensor 9, the light-emitting unit, and the optical sensor 10 are activated. The optical fiber 11 is covered with a break-point flexible material 12, and the signal magnitude transmitted by the emitted light under different bending shapes is captured by an optical processor. Combined with the pressure signal of the pressure sensor 9, they are transmitted to a signal processor 8 and converted into an electronic signal together.

[0022] The storage battery and the motor 7 are charged through the charging port 15 to provide energy. The processed data in the signal processor 8 is exported through the data transmission interface 15 and transmitted to a computer for visualization processing.
