[0002] Casual shoes are a type of footwear, and their main feature is a simple and comfortable design concept that meets people's daily wear needs. Casual shoes in the prior art are limited by their manufacturing process, so their soles have weak bending resistance and elasticity. In particular, when people walk, the toes of the foot are pressed and bent, causing the junction between the forefoot area and the middle area of ​​the shoe to bend more frequently. After long-term use, the bottom surface of the sole corresponding to the junction will have cracks along the width of the sole, which will cause the shoes to break over time. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a bending-resistant casual shoe to solve the problem in the prior art that the junction between the forefoot area and the middle area of ​​the shoe is frequently bent due to the pressure of the foot, resulting in cracks in the corresponding junction area on the bottom surface of the sole.

[0004] To achieve the above-mentioned purpose, the utility model provides a bending-resistant leisure shoe, including a sole, a shoe body and an insole, the sole is divided into a forefoot area, a middle area and a rear heel area, the bottom surface of the sole is provided with a deformation groove along the width direction of the sole, the deformation groove is arranged at the junction of the forefoot area and the middle area, the end surface of the sole is raised with a raised portion corresponding to the position of the deformation groove along the thickness direction of the sole, the radial cross-section of the raised portion and the radial cross-section of the deformation groove are both arranged in a circular arc shape and the arc directions of the two are arranged in the same manner, a metal spring is arranged in the sole, the metal spring includes a deformation portion and a support portion, the deformation portion is located in the raised portion and the radial cross-section of the deformation portion is arranged in a circular arc shape, the support portion is arranged in the rear heel area and a connecting portion is connected between the supporting portion and the deformation portion, and the connecting portion is arranged in the middle area.

[0005] The benefit of adopting the above technical scheme is that when the user walks, his forefoot area and the heel area are stepped on alternately in sequence, that is, when the user moves forward, his foot is in a tiptoeing posture, at this time the forefoot area is inclined relative to the middle area, that is, the junction of the forefoot area and the middle area is bent, so that the sole is in a certain bending shape, and the present technology is provided with a deformation groove at the junction of the forefoot area and the middle area, and the deformation groove is provided on the bottom surface of the sole along the width direction of the sole, so that when the junction of the forefoot area and the middle area is in a bent state, the deformation groove is driven to expand relatively, so that the force generated by the bending of the sole acts on the raised part, and a metal spring is provided in the sole, and the deformation part of the metal spring is located in the raised part. When the forefoot area is inclined relative to the middle area, the force brought by the relative bending of the two areas will act on the deformation part through the raised part, and the mechanical force generated by the deformation of the deformation part will The forces collide, that is, to buffer the force caused by the relative bending at the junction of the forefoot area and the middle area, part of the force is transmitted to the supporting part through the connecting part, a small part of the force is directly transmitted to the connecting part, and most of the force is buffered by the mechanical force generated by the deformation of the deformation part, so that the bending force acts excessively on the junction of the forefoot area and the middle area, resulting in stress concentration at the sole corresponding to the junction, cracks or fractures; the deformation groove in the above technology is used to adapt to the shape of the ridge and the deformation part, and at the same time avoid stress concentration at the junction when the sole is bent, and the sole in the prior art is mostly integrated.

[0007] The benefits of adopting the above technical solution are: the deformation part in the above technology is two relatively arranged deformation plates, and the two deformation plates and the conductive plate are combined in a "U" shape, so that when a single deformation plate is subjected to high force or stress concentration, part of the force can be transmitted to another deformation plate through the conductive plate, thereby avoiding stress concentration. In the above technology, the conductive plate is arranged close to the front end of the sole to avoid the conductive plate from affecting the user's daily life. At the same time, its position close to the front end of the sole is used to avoid the force from being at the junction of the forefoot area and the middle area when the force is transmitted, thereby avoiding stress concentration.

Therefore, the conductive sheet whose wave amplitude gradually decreases from one side of the shoe body to the other side of the shoe body is more suitable for the arrangement direction and fitting area of ​​the user's first toe to the fifth toe, so as to better press the conductive sheet when the user's foot presses down. At the same time, when the conductive sheet transmits part of the force output by the deformation sheet, the direction of application of the part of the force transmitted by the conductive sheet is set toward the user's foot, and the downward pressure of the user's toes will offset the force, so as to eliminate the force, thereby better buffering the force applied by the deformation sheet.

[0010] The utility model is further configured as follows: a plurality of notches are arranged on the end surface of the sole along the length direction of the sole, a plurality of the notches are opened along the width direction of the sole, a plurality of the notches are arranged in the middle area, the connecting portion is raised toward each notch position and is formed with a clamping portion, each of the clamping portions is clamped and matched with the corresponding notch, and the radial cross-section of the combination of the plurality of clamping portions is arranged in a wave shape.

[0011] The benefit of adopting the above technical solution is that the notch and the clamping part are arranged to improve the connection strength between the sole and the metal spring sheet, thereby avoiding the metal spring sheet from shaking or shifting on the sole, resulting in failure of the raised part under stress.

[0012] The utility model is further configured that: the radial cross section of the connecting portion is arranged in an arc shape, and the arc direction is arranged away from the bottom surface of the sole.

[0013] The benefits of adopting the above technical solution are: in the above technology, the radial cross-section of the connecting part is arranged in an arc shape and the arc direction is arranged away from the bottom surface of the sole. When the user is in a standing posture, part of the force applied by his foot to the middle area can be applied to the connecting part, and the slight deformation of the connecting part is used to apply part of the force to the user's foot, thereby providing a certain cushioning force and thus improving comfort.
