[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 and Figure 2 The front crotch structure of embodiment 1 comprises a front crotch piece 1 in a rectangular or isosceles trapezoidal shape, wherein the four sides of the front crotch piece 1 are respectively referred to as the first side L1, the second side L2, the third side L3 and the fourth side L4 in a clockwise direction, the line between the midpoint of the first side L1 and the midpoint of the third side L3 is referred to as the first reference line M1, the line between the midpoint of the second side L2 and the midpoint of the fourth side L4 is referred to as the second reference line M2; when the front crotch piece 1 is unfolded, the first reference line M1 and the second reference line M2 are formed in sequence along the direction of the first reference line M1. The first baffle portion 11, the second baffle portion 12, the third baffle portion 13, the fourth baffle portion 14 and the fifth baffle portion 15, wherein: one side of the first baffle portion 11 is the first side L1 of the front crotch piece 1, and one side of the fifth baffle portion 15 is the fourth side L4 of the front crotch piece 1; the front crotch piece 1 is formed by the connecting edge between the first baffle portion 11 and the second baffle portion 12, the connecting edge between the second baffle portion 12 and the third baffle portion 13, the connecting edge between the third baffle portion 13 and the fourth baffle portion 14, and the connecting edge between the fourth baffle portion 14 and the fifth baffle portion. The connecting edge between the first and second baffle portions 11 and 13 is folded as a folding edge, so that the second baffle portion 12 is sandwiched between one side portion of the first baffle portion 11 and the third baffle portion 13, and the fourth baffle portion 14 is sandwiched between the fifth baffle portion 15 and the other side portion of the third baffle portion 13. The structure in which the first baffle portion 11 and the second baffle portion 12 are folded together is referred to as a first folding structure, and the structure in which the fifth baffle portion 15 and the fourth baffle portion 14 are folded together is referred to as a second folding structure. A deformation gap 16 is formed between the first and second folding structures. The length direction of the deformation gap 16 is arranged along the second reference line M2, and the width of the deformation gap 16 is in the range of 0 mm to 30 mm. In actual application, depending on different design requirements, the deformation gap 16 can have a uniform width structure or a structure with a variable width along its length. The width variation can be irregular or gradually varying along the length direction of the deformation gap 16 (for example, a structure with a wide center and narrow ends, or a structure with a width that gradually narrows from one end to the other).

[0033] The mutually overlapping portions of the first baffle portion 11, the second baffle portion 12, the third baffle portion 13, the fourth baffle portion 14, and the fifth baffle portion 15 close to the second side edge L2 are connected and fixed together by sewing, and the mutually overlapping portions of the first baffle portion 11, the second baffle portion 12, the third baffle portion 13, the fourth baffle portion 14, and the fifth baffle portion 15 close to the fourth side edge L4 are connected and fixed together by sewing, thereby forming a structure that can be deformed into a pocket shape.

[0034] The working principle of this embodiment is as follows:

[0035] The initial state of the front baffle structure is a folded state; during use, the third baffle portion 13 is deformed along its central axis due to the force and compression, and the second baffle portion 12 and the fourth baffle portion 14 are driven by the third baffle portion 13 to fold over, so that the front baffle structure gradually switches from the folded state to the unfolded state, thereby making the front baffle structure have a larger exposed surface area, making the front crotch structure have better ductility, improving wearing comfort and heat dissipation, and being beneficial to male reproductive health and sperm motility. In addition, the design of the front baffle structure gradually deforming into a pocket-shaped structure during the process of switching from the folded state to the unfolded state allows the front baffle structure to accommodate and support the male genitals when in use, further improving wearing comfort and supporting the scrotum to show masculinity.

[0036] Example 2

[0037] like Figure 3 and Figure 4 The present invention relates to a male underwear according to Example 2, comprising a pant piece 2, a front crotch structure, and an elastic band 3. The pant piece 2 comprises side pant pieces 21 and a bottom pant piece 22. The front crotch structure is the same as that described in Example 1. The first and third side edges of the front crotch piece 1 of the front crotch structure are respectively connected to the respective sides of the side pant piece 21 to form a cylindrical structure. The bottom pant piece 22 is connected to one end of the cylindrical structure to form leg holes for the underwear, and the other end of the cylindrical structure serves as a waist opening for the underwear. The second side edge of the front crotch piece 1 of the front crotch structure is connected to the bottom pant piece 22, and the second side edge of the front crotch piece 1 of the front crotch structure is adjacent to the waist opening of the underwear. The elastic band 3 is provided along the edge of the waist opening of the underwear. In this embodiment, the deformation slit 16 of the front crotch piece 1 of the front crotch structure is a structure that is wide in the middle and narrow at both ends. The width of the deformation slit 16 at both ends is 0 mm, and the width of the middle portion of the deformation slit 16 is 30 mm.

[0038] The working principle of this embodiment is as follows:

[0039] By adopting a front crotch structure that is stretchable and can be deformed into a pocket-shaped structure as the front crotch part of the underwear, the men's underwear has good wearing comfort and heat dissipation effect when worn, which is beneficial to male reproductive health and sperm vitality. The front crotch structure can lift the scrotum to show masculinity.

[0040] like Figure 4 As shown, the third baffle portion 13 of the front crotch structure is located on the inside of the underwear, while the first baffle portion 11 and the fifth baffle portion 15 are located on the outside of the underwear. When the men's underwear is worn, the third baffle portion 13 is squeezed and deformed toward the outside of the underwear through the deformation slit 16. In this embodiment, the deformation slit 16 provides a deformation channel for the third baffle portion 13, allowing the third baffle portion 13 to deform from the inside of the underwear and move to the outside of the underwear when the front crotch structure switches from a folded state to an unfolded state. This design ensures that the men's underwear has good ductility and a more aesthetically pleasing appearance when not worn.

[0041] Example 3

[0042] like Figure 5 and Figure 6 This is a pair of men's underwear according to Example 3. The difference between Example 3 and Example 2 is that the third baffle portion 13 of the front crotch structure is located on the outside of the underwear, while the first baffle portion 11 and the fifth baffle portion 15 are located on the inside. The deformation slit 16 of the front crotch panel 1 is of uniform width, with a width of 60 mm. In this embodiment, the deformation slit 16 provides a clearance opening for the third baffle portion 13. When the men's underwear is worn, the male genitals directly contact the third baffle portion 13 through the deformation slit 16, squeezing and deforming the third baffle portion 13. This design prevents the connecting edges between the third baffle portion 13 and the second baffle portion 12, and between the third baffle portion 13 and the fourth baffle portion 14, from scratching the human skin during the process of switching the front crotch structure from a folded state to an unfolded state, thereby improving wearing comfort.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications, combinations, and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be within the scope of the claims of the present invention.
