[0002] With the development of society and the improvement of people's living standards, outdoor sports as a healthy lifestyle are more and more people like. However, the current market of outdoor pants in the design has not been able to fully meet the heat dissipation needs of human body in sports. In the traditional design, the pant type air permeability needs to be improved, which cannot quickly discharge sweat, resulting in heat accumulation. The structure design of the existing trousers is general, which usually adopts exposed mesh cloth or opening, lacks targeted heat dissipation channel and ventilation area. And, as a part of dressing, trousers are also very important in appearance. Therefore, developing a pair of trousers with good heat dissipation function and beautiful appearance has become the design difficulty of clothing designers. UTILITY MODEL CONTENT

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application.

[0023] As shown in the accompanying drawings, the embodiments elaborate a pair of trousers with hidden heat dissipation structure. Figs. 1-3 The trousers realize efficient heat dissipation and take into account the comfort, functionality and aesthetics of wearing through unique live hinge structure and a series of related designs.

[0024] Embodiment one

[0025] The basic structure of the present application is implemented, and the specific structure includes a live hinge structure made of light, thin, tough and elastic material, and the live hinge structure is fixed to the junction of the posterior waist area and the hip area by a double line of reinforced sewing stitch. Fig. 3 In the embodiment, the live hinge structure 1 is designed in an inverted trapezoidal shape, with an upper edge length of 28 cm, a lower edge length of 34 cm and a height of 12 cm. In other embodiments, the live hinge structure 1 can also be designed in a square strip shape.

[0026] In the embodiment, the double line of reinforced sewing stitch 4 specifically includes a first line of stitch and a second line of stitch. The first line of stitch is 0.3 cm away from the edge and has a density of 12 needles per 3 cm. The second line of stitch is 0.5 cm away from the first line and has a density of 14 needles per 3 cm, using Tex 70 high-strength polyester thread (breaking strength ≥ 45 N) to enhance the sewing strength.

[0027] The light, thin, tough and elastic material used in the live hinge structure body can be specifically a polyamide elastic fiber (65% by weight) and spandex (35% by weight) blended fabric, which is treated by double-sided sanding to control the grammage at 95 g / m2±5%, with a warp elastic modulus of 88% and a weft elastic modulus of 77%.

[0028] The detachable structure 1 is fixedly connected with the trousers body by double-line reinforced sewing thread 4, forming a three-dimensional ventilation cavity which can be naturally unfolded and closed, and the maximum opening angle is greater than or equal to 60°.

[0029] Further, the detachable structure 1 is provided with opening and closing adjusting device at the edge, including invisible snap 5 and / or magic tape 6 components distributed at intervals, the snap distance is 8-12 cm, and the effective adhesion length of the magic tape is 3-5 cm. The invisible snap can be arranged at a free edge of the detachable structure at an interval of 10 cm, the snap base diameter is 8 mm, the embedding depth is 1.2 mm, and the surface is covered with 0.2 mm thick TPU film to realize visual hiding. The magic tape component is located between the snaps, the hook surface is 4 cm long and 1.5 cm wide, and the wool surface is 5 cm long and 2 cm wide, and a low-noise adhesive fastener tape with a peel strength greater than or equal to 1.8 N / cm can be used. 2 .

[0030] Further, the inner edge of the detachable structure 1 is provided with an antibacterial filter screen 7, which is sewn at the opening of the detachable structure of the trousers body, and the antibacterial filter screen adopts a 40-60 mesh stainless steel wire mesh and a polyester fiber composite layer structure, and the outer edge is reinforced by a 0.5 cm wide edge strip. In this embodiment, the antibacterial filter screen is a three-layer composite structure: an outer layer of 50 mesh 316L stainless steel wire mesh (wire diameter 0.08 mm), a middle layer of polyester melt-blown filter layer (fiber diameter 3-5 μm), and an inner layer of breathable nylon mesh (porosity 82%).

[0031] The filter screen pore density gradually changes from 80 holes / cm 2 to 120 holes / cm 2 along the airflow direction, and the edge is fixed to the inner edge of the detachable structure by ultrasonic welding.

[0032] Example Two

[0033] This embodiment is further optimized on the basis of example one, including:

[0034] The waistband and the detachable structure are designed to be elastically linked, and the detachable structure is linked with the waistband elastic band by an elastic connecting band, and when the waistband stretching amount exceeds 15%, the automatic unfolding angle of the detachable structure increases by 20%-30%. For example, 12 mm wide silicone-coated Spandex can be used as the elastic connecting band, and the elongation rate is greater than or equal to 300%, and the two ends are connected with the 5 cm wide rubber band of the waistband elastic band through Y-shaped bifurcated structure. When the waistband stretching amount reaches 15% (corresponding to a waist circumference expansion of 7-8 cm), the unfolding angle of the detachable structure can be increased from the basic value of 60° to 72°±3°.

[0035] Further, the surface of the loose-leaf structure is compounded with a temperature-sensitive color-changing coating, which has a reversible color change in the range of 28-32 DEG C, with a color difference DE of 5 or more, and can be used as a reference for real-time temperature changes, suitable for distinguishing the stable environment during outdoor activities, and also has aesthetic properties.

[0036] Further, the position of the hip region corresponding to the loose-leaf structure is provided with a differential elastic zone 8, which has an elastic modulus 15-20% higher than other parts, forming a directional deformation guide structure. As an optimization design in the aspect of mechanics, the differential elastic zone can be obtained by increasing the warp density (for example, from 120 to 138 per inch) during fabric weaving, so that the elastic modulus of this area is increased, and a three-dimensional arch structure is formed when the loose-leaf is unfolded. The differential elastic zone reduces the resistance to movement and improves the wearing comfort.

[0037] The antibacterial filter screen is connected to the loose-leaf structure by a miniature magnetic buckle, and the pore density of the filter screen is designed to change in a gradient along the airflow direction to improve the air permeability.

[0038] From the perspective of heat dissipation efficiency, if the unfolded area of the loose-leaf structure is too small, such as less than 15%, the ventilation volume is limited, and it is difficult to meet the large heat dissipation demand of the waist and hip area of the human body during movement or hot environment; while if the unfolded area is too large, more than 25%, although the ventilation volume can be greatly increased, it may affect the overall structural stability and aesthetics of the trousers, and also more easily cause wrinkles or unevenness when the loose-leaf is closed. By accurately controlling the area ratio within this range, both sufficient air flow channels can be ensured to achieve efficient heat dissipation, and the overall style and appearance coordination of the trousers can be maintained.

[0039] When the loose-leaf structure is in the closed state, the flatness of the outer surface has strict requirements, and the error needs to be controlled to be ≤2mm. To provide an extreme comfortable experience for the wearer and maintain the overall aesthetic appearance of the trousers.

[0040] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
