[0047] The joints of the human body (such as the knee joint, elbow joint, and shoulder joint, etc.) are important parts that enable the human body to move freely. Since the muscle protection layer at the joints is relatively thin, the joints are easily attacked by cold and moisture, so the joints are easily damaged. Especially the elderly, women, and athletes are more likely to suffer from joint injuries, joint coldness, and joint pain. These problems are commonly manifested clinically as synovitis, knee effusion, joint cold pain, and rheumatism. Therefore, it is very necessary to protect the joints of the human body to maintain the health of the joints.

[0048] The human knee joint is an important part that enables the human body to move freely, and is also one of the important load-bearing joints that supports the weight of the human body. Most of the existing knee pads for protecting the knee joints are mainly made of cotton in terms of the fabric selection of the knee pads, and the design of the knee pad structure is mainly sewing the entire piece of fabric, which makes the knee joint stuffy and airtight, and is not convenient for the movement of the knee joint.

[0049] US37931309A discloses a kneepad. The kneepad is provided with a hemispherical depression at the position corresponding to the knee joint, and a disc-shaped layer is provided in the hemispherical depression, so as to protect the knee joint. The kneepad has the disadvantages that the disc-shaped layer and the hemispherical depression hinder air flow to a certain extent, causing the knee joint to be stuffy and airtight, and it is also inconvenient to move the knee joint.

[0050] Therefore, the main purpose of the present invention is to provide a knee pad with an opening structure, by providing an opening on the knee pad to improve the structure of the knee pad, thereby solving the technical problem that most of the existing knee pads will cause the knee joint to be stuffy and airtight, and at the same time, it is inconvenient for the movement of the knee joint.

[0051] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0052] See also Figure 1-5 The present invention provides a kneepad with an open structure, wherein the kneepad with an open structure comprises a kneepad body 100. Figure 1 and Figure 2 As shown, the kneepad body 100 includes a first kneepad sheet 110 and a second kneepad sheet 120 that are fixedly connected. Figure 3As shown, the first knee pad 110 includes a first knee pad first side 111, a first knee pad second side 112 and a first through hole 113. The first knee pad first side 111 and the first knee pad second side 112 are two side surfaces of the first knee pad 110 and are arranged opposite to each other; in some embodiments, the thickness of the first knee pad 110 is unique (the specific thickness can be set according to actual needs and is not limited here), so that the surface of the first knee pad first side 111 is parallel to the surface of the first knee pad second side 112. The first knee pad first side 111 is close to the user's skin and can be used to contact the user's skin, that is, when the user wears the knee pad body 100 (the first knee pad 110 can be fixed to the user's knee joint by setting Velcro on the first knee pad 110), the surface of the first knee pad first side 111 is not exposed to the outside of the user, and at least a part of the surface can contact the user's skin at the knee joint. In some embodiments, a skin-friendly material layer may be covered on the first side 111 of the first knee pad so that the skin-friendly material layer contacts the user's skin. The second side 112 of the first knee pad is away from the user's skin, that is, when the user wears the knee pad body 100, the surface of the second side 112 of the first knee pad is exposed outside the user and does not contact the user's skin.

[0053] like Figure 3 As shown, the first through hole 113 is provided on the first knee pad 110, and passes through the first side 111 of the first knee pad and the second side 112 of the first knee pad. The first through hole 113 includes a first opening 1131 located on the first side 111 of the first knee pad and a second opening 1132 located on the second side 112 of the first knee pad. The shape of the first opening 1131 or the shape of the second opening 1132 can be set to, but not limited to, a circle, an ellipse, a triangle, etc. according to actual needs. When the user wears the knee pad body 100, the first through hole 113 corresponds to the position of the patella of the user's knee joint, and the patella can be enclosed in the first through hole 113 (that is, the first through hole 113 can enclose the patella within the space surrounded by the inner surface of the first through hole 113 and its extended surface).

[0054] like Figure 4As shown, the second knee pad 120 includes a second knee pad first side 121, a second knee pad second side 122, and a second knee pad edge 123. The second knee pad first side 121 and the second knee pad second side 122 are two side surfaces of the second knee pad 120, and are arranged opposite to each other. The second knee pad edge 123 is located between the second knee pad first side 121 and the second knee pad second side 122, that is, the second knee pad first side 121 and the second knee pad second side 122 are located on opposite sides of the second knee pad edge 123; in some embodiments, the second knee pad 120 has a unique thickness (the specific thickness can be set according to actual needs, which is not limited here), so that the surface of the second knee pad first side 121 is parallel to the surface of the second knee pad second side 122, and each part of the second knee pad edge 123 is uniform. The first side 121 of the second knee pad can be used to contact with the user's skin, that is, when the user wears the knee pad body 100, the surface of the first side 121 of the second knee pad is not exposed to the outside of the user, and at least a portion of the surface of the first side 121 of the second knee pad can contact with the user's skin at the knee joint; wherein the first side 121 of the second knee pad can contact with the skin at the knee joint when the knee joint is not bent and / or bent. The second side 122 of the second knee pad is away from the user's skin, that is, when the user wears the knee pad body 100, the surface of the second side 122 of the second knee pad does not contact with the user's skin.

[0055] like Figure 3 , Figure 4 and Figure 5As shown, the second side 122 of the second knee guard and the first through hole 113 form a first opening 130, wherein the second opening 1132 of the first through hole 113 is the opening of the first opening 130, and at least a portion of the inner surface of the first through hole 113 and the surface of the second side 122 of the second knee guard are the inner surface of the first opening 130. A channel for air flow is formed between the first opening 130 and the first orifice 1131 (not shown in the figure); in some embodiments, the first knee pad 110 and the second knee pad 120 may be made of but not limited to a textured elastic material (for example, textured polyester fiber), and the textured elastic material contains different fibers, which form a texture that facilitates air convection with the surface of the first knee pad 110 in contact with the skin or the surface of the second knee pad 120 in contact with the skin, so that air can flow between the first side 111 of the first knee pad and the second side 122 of the first knee pad, and between the first side 121 of the second knee pad and the second side 122 of the second knee pad, that is, air can pass through between the first opening 130 and the first orifice 1131 to contact the skin, thereby increasing breathability and improving skin-friendliness. In some embodiments, the second knee pad 120 is provided with one or more second through holes (not shown in the figure) passing through the first side 121 of the second knee pad and the second side 122 of the second knee pad, and / or one or more second openings (not shown in the figure) located on the second side 122 of the second knee pad; wherein a channel for air flow is formed between the second opening and the first opening 1131, and the second through hole and the second opening are both located in the first through hole 113 (that is, the second through hole and the second opening are both located within the space enclosed by the inner surface of the first through hole 113 and its extended surface), thereby facilitating air circulation and helping to discharge moisture, while increasing air permeability and reducing the feeling of stuffiness.

[0056] In some embodiments, Figure 3 , Figure 4 and Figure 5 As shown, the surface of the second side 122 of the second knee pad and the surface of the first side 111 of the first knee pad can be attached and fixed together so that a portion of the surface of the second side 122 of the second knee pad just covers the first opening 1131 of the first through hole 113, thereby at least a portion of the inner surface of the first through hole 113, the second opening 1132 and this portion of the surface of the second side 122 of the second knee pad form the first opening 130.

[0057] In some embodiments, Figure 3 , Figure 4 and Figure 7As shown, the surface of the edge 123 of the second knee guard can be fitted and fixed together with the inner surface of the first through hole 113, so that the entire surface of the second side 122 of the second knee guard can serve as the bottom surface of the first opening 130, and form the first opening 130 together with the second hole 1132 and at least a portion of the inner surface of the first through hole 113.

[0058] In some embodiments, Figure 3 , Figure 4 and Fig. 9 As shown, the surface of the edge 123 of the second knee guard piece can be fitted and fixed to the surface of the first side 111 of the first knee guard piece located at the first opening 1131, so that a part of the surface of the second side 122 of the second knee guard piece just serves as a part of the side surface of the first opening 130, and the remaining part of the surface of the second side 122 of the second knee guard piece just serves as the bottom surface of the first opening 130, and forms the first opening 130 together with the second opening 1132 and the inner surface of the first through hole 113.

[0059] Among them, Figure 5 and Fig.15 As shown, when the first knee guard 110 is in a planar unfolded state (that is, the first knee guard 110 is unfolded into a planar structure, wherein the surface of the first side 111 of the first knee guard and the surface of the second side 112 of the first knee guard are both unfolded into a plane), the longitudinal width of the orifice of the first opening 130 (that is, the second orifice 1132) is a1. In some embodiments, the contour shape of the second orifice 1132 can be set to, but is not limited to, a substantially rectangular shape, and the longitudinal width of the rectangle is a1.

[0060] like Fig.15 and Fig.16As shown, when the user wears the knee brace body 100 and the user's knee joint is not bent (that is, the user's thigh, knee joint and calf are generally in a straight line structure without a bending angle), the first opening 130 corresponds to the position of the patella of the user's knee joint. The longitudinal width of the opening of the first opening 130 (that is, the second opening 1132) is b1, b1≥a1; that is, when the user wears the knee brace body 100 and the user's knee joint is not bent, due to the interaction force between the knee joint and the knee brace body 100, the second opening 1132 can be expanded compared to when the first knee brace sheet 110 is in the flat unfolded state, which not only ensures the user's comfort when wearing the knee brace body 100 but also facilitates the ventilation of the knee joint. In some embodiments, the contour shape of the second opening 1132 can be set to, but not limited to, a basic first ellipse, and the longitudinal short diameter of the first ellipse (that is, twice the length of the longitudinal short semi-axis of the first ellipse) is b1, b1≥a1.

[0061] like Figure 6 , Figure 8 , Fig.10 and Fig.16 As shown, when the user wears the knee pad body 100 and the user's knee joint is bent (that is, the user's thigh, knee joint and calf part generally present a non-linear structure with a certain bending angle), the first opening 130 corresponds to the position of the patella of the user's knee joint, and at least a portion of the second side 122 of the second knee pad extends from the second opening 1132 outside the first opening 130 (that is, outside the space enclosed by the inner surface of the first opening 130). The longitudinal width of the orifice of the first opening 130 (i.e., the second orifice 1132) is c1, c1>b1; that is, when the user wears the knee brace body 100 and the knee joint of the user is bent, the interaction force between the knee joint and the knee brace body 100 continues to increase during the bending of the knee joint, so the second orifice 1132 is further expanded compared to when the first knee brace sheet 110 is in the planar unfolded state and when the knee joint is not bent, thereby ensuring the ventilation of the knee joint and reducing the feeling of stuffiness during the bending of the knee joint. In some embodiments, the contour shape of the second orifice 1132 can be set to, but not limited to, a basic second ellipse, and the longitudinal minor diameter of the second ellipse (i.e., twice the length of the longitudinal minor semi-axis of the second ellipse) is c1, c1>b1.

[0062] In the above embodiment of the present invention, the kneepad body is configured as a two-piece structure in which the first kneepad sheet and the second kneepad sheet are attached and fixed together, and a first through hole is opened on the first kneepad sheet so that the second kneepad sheet and the first through hole form a first opening corresponding to the position of the patella of the user's knee joint. During the bending process of the user's knee joint, the opening of the first opening is gradually expanded so that at least a portion of the second layer protrudes out of the opening, thereby not only reserving space for the movement of the patella, but also facilitating the ventilation of the patella, preventing stuffiness, and facilitating the removal of moisture between the kneepad body and the skin.

[0063] Example 1

[0064] In this example, please continue to refer to Figure 5 and Figure 6 , the second side 122 of the second knee pad is attached to and fixed to the first side 111 of the first knee pad (for example, pressed and fixed together by a hot press), wherein the second side 122 of the second knee pad can be attached to and fixed to a part or all of the first side 111 of the first knee pad, and there is no limitation here. The second side 122 of the second knee pad covers the first opening 1131; that is, the part of the second side 122 of the second knee pad that is attached to and fixed to the first side 111 of the first knee pad should at least cover the first opening 1131, so that the second side 122 of the second knee pad, the inner surface of the first through hole 113 and the first opening 1131 form the first opening 130, wherein the part of the second side 122 of the second knee pad that is attached to and fixed to the first side 111 of the first knee pad is the bottom surface of the inner surface of the first opening 130, the inner surface of the first through hole 113 is the side surface of the inner surface of the first opening 130, and the second opening 1132 is the opening of the first opening 130.

[0065] Among them, Figure 5 As shown, when the first knee pad 110 is in a planar unfolded state, the second side 122 of the second knee pad is a planar structure and does not extend from the second hole 1132 outside the first opening 130, so that when the user wears the knee pad body 100 and the user's knee joint is bent, the second hole 1132 is prevented from being affected by the second side 122 of the second knee pad located outside the first opening 130 and cannot be expanded normally.

[0066] like Fig.16As shown, when the user wears the knee pad body 100 and the user's knee joint is not bent, the skin at the knee joint contacts at least a portion of the first side 111 of the first knee pad and / or at least a portion of the first side 121 of the second knee pad. Due to the interaction force between the knee joint and the knee pad body 100, the second orifice 1132 can be expanded compared to when the first knee pad 110 is in the planar unfolded state; when the second orifice 1132 is expanded, the second side 122 of the second knee pad is a non-planar structure of a basic arc surface convex toward the direction of the second orifice 1132, and does not extend out of the first opening 130 from the second orifice 1132, so that when the user wears the knee pad body 100 and the user's knee joint is bent, the second orifice 1132 is prevented from being affected by the second side 122 of the second knee pad located outside the first opening 130 and cannot be expanded normally.

[0067] like Figure 6 As shown, when the user wears the kneepad body 100 and the user's knee joint is bent, the skin at the knee joint contacts at least a portion of the first side 111 of the first kneepad piece and / or at least a portion of the first side 121 of the second kneepad piece. Since the interaction force between the knee joint and the kneepad body 100 continues to increase during the bending of the knee joint, the second orifice 1132 is further expanded compared to when the first kneepad piece 110 is in the planar unfolded state and when the knee joint is not bent; at the second orifice 1132 When being further expanded, the second side 122 of the second knee pad is a non-planar structure with a basic wavy surface protruding in the direction of the second opening 1132, and the wavy surface at least partially covers the entire arc surface (when the user wears the knee pad body 100 and the user's knee joint is not bent) (that is, the wavy surface at least completely covers the arc surface), and at least a part of the wavy surface extends out of the second opening, thereby facilitating the adaptation of the knee pad body 100 to the movement of the knee joint, and ensuring the breathability of the wearer and reducing the feeling of stuffiness during the bending process of the knee joint.

[0068] In this embodiment, the first knee pad 110 may be made of but not limited to elastic material (for example, elastic polyester fiber or textured polyester fiber), the second knee pad 120 may be made of but not limited to elastic material (for example, elastic polyester fiber or textured polyester fiber), and the second side 122 of the second knee pad is seamlessly fitted and fixed to the first side 111 of the first knee pad, thereby ensuring that the knee pad body is adapted to the bending movement of the knee joint, and when the user wears the knee pad body 100 and the user's knee joint is bent, at least a portion of the second side 122 of the second knee pad extends out of the first opening 130 from the second hole 1132.

[0069] Example 2

[0070] In this example, please continue to refer to Figure 7 and Figure 8 , the edge 123 of the second knee pad is fitted and fixed to the inner surface of the first through hole 113 (for example, pressed and fixed together by a heat press), and the second side 122 of the second knee pad is located in the first through hole 113 (that is, the second side 122 of the second knee pad is located within the space surrounded by the inner surface of the first through hole 113), so that the second side 122 of the second knee pad, the inner surface of the first through hole 113 and the second orifice 1132 form the first opening 130, wherein the second orifice 1132 is the orifice of the first opening 130. In some embodiments, the first side 121 of the second knee pad is also located in the first through hole 113, so that when the user wears the knee pad body 100 and the knee joint of the user is bent, the second side 122 of the second knee pad is prevented from being affected by the first side 121 of the second knee pad and being unable to extend out of the first opening 130 from the second orifice 1132.

[0071] Among them, Figure 7 As shown, when the first knee pad 110 is in a planar unfolded state, the second side 122 of the second knee pad is a planar structure and does not extend from the second hole 1132 outside the first opening 130, so that when the user wears the knee pad body 100 and the user's knee joint is bent, the second hole 1132 is prevented from being affected by the second side 122 of the second knee pad located outside the first opening 130 and cannot be expanded normally.

[0072] like Fig.16 As shown, when the user wears the knee pad body 100 and the user's knee joint is not bent, the skin at the knee joint contacts at least a portion of the first side 111 of the first knee pad. Due to the interaction force between the knee joint and the knee pad body 100, the second opening 1132 can be expanded compared to when the first knee pad 110 is in the planar unfolded state; when the second opening 1132 is expanded, the second side 122 of the second knee pad is a non-planar structure of a basic first arc surface protruding toward the direction of the second opening 1132, and does not extend out of the first opening 130 from the second opening 1132, so that when the user wears the knee pad body 100 and the user's knee joint is bent, the second opening 1132 is prevented from being affected by the second side 122 of the second knee pad located outside the first opening 130 and unable to be expanded normally.

[0073] like Figure 8As shown, when the user wears the kneepad body 100 and the user's knee joint is bent, since the interaction force between the knee joint and the kneepad body 100 continues to increase during the bending process of the knee joint, the second opening 1132 is continued to be expanded compared to when the first kneepad piece 110 is in the planar unfolded state and when the knee joint is not bent; when the second opening 1132 is continued to be expanded, the second side 122 of the second kneepad piece is a non-planar structure of a basic second curved surface protruding toward the direction of the second opening 1132, the second curved surface at least partially covers the entire first curved surface (when the user wears the kneepad body 100 and the user's knee joint is not bent) (that is, the second curved surface at least completely covers the first curved surface), and at least a portion of the second curved surface extends out of the first opening 130, thereby facilitating the adaptation of the kneepad body 100 to the movement of the knee joint, and ensuring the breathability of the wearer and reducing the feeling of stuffiness during the bending process of the knee joint.

[0074] In this embodiment, the first knee pad 110 may be made of but not limited to plastic material (e.g., ABS plastic) and / or cloth (e.g., polyester fiber), the second knee pad 120 may be made of but not limited to flexible material (e.g., silicone) and / or elastic material (e.g., elastic polyester fiber), and the edge 123 of the second knee pad is seamlessly fitted and fixed to the inner surface of the first through hole 113, thereby ensuring that the knee pad body is adapted to the bending movement of the knee joint, and when the user wears the knee pad body 100 and the user's knee joint is bent, at least a portion of the second side 122 of the second knee pad extends out of the first opening 130 from the second hole 1132.

[0075] Example 3

[0076] In this example, please continue to refer to Figure 3 , Fig. 9 and Fig.10, the edge 123 of the second knee pad is attached to and fixed to the first side 111 of the first knee pad (for example, pressed and fixed together by a heat press); in some embodiments, the fixed connection between the edge 123 of the second knee pad and the first side 111 of the first knee pad is located close to the first orifice 1131, so that the second side 122 of the second knee pad and the first through hole 113 form the first opening 130, wherein the second side 122 of the second knee pad includes a first portion 122a and a second portion 122b, the inner surfaces of the first portion 122a and the first through hole 113 are the side surfaces of the inner surface of the first opening 130, the second portion 122b is the bottom surface of the inner surface of the first opening 130, and the second orifice 1132 is the orifice of the first opening 130. In some embodiments, the connection between the first portion 122a and the second portion 122b can be set as follows Fig. 9 The sharp transition is shown, so that the first portion 122a does not need to be made of elastic material.

[0077] Among them, Fig. 9 As shown, when the first knee guard 110 is in a planar unfolded state, the first part 122a is a planar or curved structure, the second part 122b is a planar structure, the first part 122a and the second part 122b as a whole form a basic concave surface that is recessed in the direction of the first side 121 of the second knee guard, and the concave surface is in the shape of a guide rail, wherein the first part 122a forms the side surface of the guide rail, and the second part 122b forms the bottom surface of the guide rail; and neither the first part 122a nor the second part 122b extends out of the first opening 130 from the second hole 1132, so that when the user wears the knee guard body 100 and the user's knee joint is bent, the second hole 1132 is prevented from being affected by the second side 122 of the second knee guard located outside the first opening 130 and cannot be expanded normally.

[0078] like Fig.16As shown, when the user wears the knee pad body 100 and the user's knee joint is not bent, the skin at the knee joint contacts at least a portion of the first side 111 of the first knee pad and at least a portion of the second side 112 of the second knee pad. Due to the interaction force between the knee joint and the knee pad body 100, the second orifice 1132 can be expanded compared to when the first knee pad 110 is in the planar unfolded state; when the second orifice 1132 is expanded, the second portion 122b is a non-planar structure of a basic arc surface protruding toward the direction of the second orifice 1132, and the first portion 122a and the second portion 122b do not extend from the second orifice 1132 to the outside of the first opening 130, so that when the user wears the knee pad body 100 and the user's knee joint is bent, the second orifice 1132 is prevented from being affected by the second side 122 of the second knee pad located outside the first opening 130 and cannot be expanded normally.

[0079] like Fig.10 As shown, when the user wears the kneepad body 100 and the user's knee joint is bent, the skin at the knee joint contacts at least a portion of the first side 111 of the first kneepad. Since the interaction force between the knee joint and the kneepad body 100 continues to increase during the bending of the knee joint, the second orifice 1132 is further expanded compared to when the first kneepad 110 is in the planar unfolded state and when the knee joint is not bent. When the second orifice 1132 is further expanded, the second side 122 of the second kneepad is formed by the concave shape of the guide rail. The non-planar structure forms a basically wavy surface (including the first part 122a and the second part 122b of the second side 122 of the second knee pad), and the wavy surface at least partially covers the entire arc surface (when the user wears the knee pad body 100 and the user's knee joint is not bent) (that is, the wavy surface at least completely covers the arc surface), and at least a part of the wavy surface extends out of the first opening 130, so as to facilitate the adaptation of the knee pad body 100 to the movement of the knee joint, and ensure the breathability of the wearer and reduce the stuffiness during the bending process of the knee joint.

[0080] In this embodiment, the first knee pad 110 may be made of but not limited to plastic material (e.g., ABS plastic) and / or cloth (e.g., polyester fiber), the second knee pad 120 may be made of but not limited to flexible material (e.g., silicone) or cloth (e.g., polyester fiber), and the edge 123 of the second knee pad is seamlessly fitted and fixed to the first side 111 of the first knee pad, thereby ensuring that the knee pad body is adapted to the bending movement of the knee joint, and when the user wears the knee pad body 100 and the user's knee joint is bent, at least a portion of the second side 122 of the second knee pad extends out of the first opening 130 from the second hole 1132.

[0081] Example 4

[0082] In this example, please continue to refer to Figure 11-14 , the edge 123 of the second knee pad is fitted and fixed to the inner surface of the first through hole 113 (for example, pressed and fixed together by a heat press), and the second side 122 of the second knee pad is located in the first through hole 113 (that is, the second side 122 of the second knee pad is located within the space enclosed by the inner surface of the first through hole 113), so that the second side 122 of the second knee pad, the inner surface of the first through hole 113 and the second orifice 1132 form the first opening 130, wherein the second orifice 1132 is the orifice of the first opening 130. In some embodiments, the first side 121 of the second knee pad is also located in the first through hole 113, so that when the user wears the knee pad body 100 and the user's knee joint is bent, the second side 122 of the second knee pad is prevented from being affected by the first side 121 of the second knee pad and unable to extend out of the first opening 130 from the second orifice 1132. The second side 122 of the second knee pad is serrated (such as Fig.11 or Fig.13 as shown) and / or wavy (as Fig.12 or Fig.14 The present invention relates to a foldable non-planar structure (as shown), and includes one or more folding units 1221, that is, the surface of the second side 122 of the second knee pad can be folded in a zigzag shape (the folding units 1221 are all folding units with a zigzag structure), or in a wavy shape (the folding units 1221 are all folding units with a wavy structure), or in a zigzag plus wavy mixed folding (the folding units 1221 include both folding units with a zigzag structure and folding units with a wavy structure).

[0083] Among them, Fig.11 or Fig.13As shown, when the first knee guard 110 is in a planar unfolded state, the folding units 1221 are close to each other, so that the second side 122 of the second knee guard is a contracted folded structure as a whole.

[0084] When the user wears the knee pad body 100 and the user's knee joint is not bent, the skin at the knee joint contacts at least a portion of the first side 111 of the first knee pad. Due to the interaction force between the knee joint and the knee pad body 100, the second opening 1132 can be expanded compared to when the first knee pad 110 is in the planar unfolded state; when the second opening 1132 is expanded, the folding units 1221 move away from each other, so that the second side 122 of the second knee pad is an open folding structure as a whole.

[0085] like Fig.12 or Fig.14 As shown, when the user wears the kneepad body 100 and the user's knee joint is bent, the skin at the knee joint contacts at least a portion of the first side 111 of the first kneepad. Since the interaction force between the knee joint and the kneepad body 100 continues to increase during the bending of the knee joint, the second orifice 1132 is continuously expanded compared to when the first kneepad 110 is in the planar unfolded state and when the knee joint is not bent. When the second orifice 1132 is continuously expanded, the folding units 1221 continue to move away from each other, so that the second side 122 of the second kneepad as a whole is a continuously opened folding structure, and at least a portion of the second side 122 of the second kneepad in a continuously opened state (that is, at least a portion of all the folding units 1221) extends out of the first opening 130, thereby facilitating the adaptation of the kneepad body 100 to the movement of the knee joint and ensuring the breathability of the wearer and reducing the feeling of stuffiness during the bending of the knee joint.

[0086] In this embodiment, there is no limitation on the material of the first knee pad 110 and the material of the second knee pad 120 .

[0087] Example 5

[0088] In this example, please continue to refer to Figure 17-19The edge 123 of the second knee pad is fitted and fixed to the inner surface of the first through hole 113 (for example, a snap fit can be achieved by providing snap fittings on the edge 123 of the second knee pad and the inner surface of the first through hole 113), and the second side 122 of the second knee pad is located in the first through hole 113 (that is, the second side 122 of the second knee pad is located within the space enclosed by the inner surface of the first through hole 113), so that the second side 122 of the second knee pad, the inner surface of the first through hole 113 and the second orifice 1132 form the first opening 130, wherein the second orifice 1132 is the orifice of the first opening 130. The second side 122 of the second knee guard is a non-planar structure and includes at least two folding surfaces 1222, and at least two of the folding surfaces 1222 are rotatably connected to each other; in some embodiments, the first side 121 of the second knee guard corresponding to each folding surface 1222 is different, and the two adjacent folding surfaces 1222 can be rotated around the straight line between the two connecting points by respectively arranging the two lateral ends of one folding surface 1222 at the lateral ends of the first side 121 of the second knee guard corresponding to an adjacent folding surface 1222.

[0089] Among them, Fig.17 and Fig.19 As shown, when the first knee guard 110 is in a planar unfolded state, each of the folding surfaces 1222 is a plane (such as Fig.19 as shown) or curved surface (as shown Fig.17 As shown in the figure), the folding surfaces 1222 are close to each other and overlap each other.

[0090] When the user wears the knee pad body 100 and the user's knee joint is not bent, the skin at the knee joint contacts at least a portion of the first side 111 of the first knee pad. Due to the interaction force between the knee joint and the knee pad body 100, the second opening 1132 can be enlarged compared to when the first knee pad 110 is in the planar unfolded state; when the second opening 1132 is enlarged, the folding surfaces 1222 move away from each other, and all the folding surfaces 1222 form a convex structure that protrudes toward the direction of the second opening 1132 as a whole; in some embodiments, the convex surface may be a non-planar structure such as but not limited to a curved surface, a serrated surface, and a wavy surface.

[0091] like Fig.18As shown, when the user wears the kneepad body 100 and the user's knee joint is bent, the skin at the knee joint contacts at least a portion of the first side 111 of the first knee pad. Since the interaction force between the knee joint and the kneepad body 100 continues to increase during the bending of the knee joint, the second orifice 1132 is continuously expanded compared to when the first knee pad 110 is in the planar unfolded state and when the knee joint is not bent. When the second orifice 1132 is continuously expanded, the folding surfaces 1222 continue to move away from each other, and the convex surface formed by all the folding surfaces 1222 continues to protrude outward and extend out of the first opening 130, thereby facilitating the adaptation of the kneepad body 100 to the movement of the knee joint and ensuring the breathability of the wearer and reducing the feeling of stuffiness during the bending of the knee joint.

[0092] In this embodiment, there is no limitation on the material of the first knee pad 110 and the material of the second knee pad 120 .

[0093] In summary, the present invention provides a kneepad with an opening structure, the kneepad with an opening structure comprises a kneepad body, the kneepad body comprises a first kneepad sheet and a second kneepad sheet. The first kneepad sheet comprises a first side of a first kneepad sheet and a second side of a first kneepad sheet arranged opposite to each other, and a first through hole penetrating the first side of the first kneepad sheet and the second side of the first kneepad sheet. The first side of the first kneepad sheet is close to the user's skin, and the second side of the first kneepad sheet is away from the user's skin. The first through hole comprises a first orifice located on the first side of the first kneepad sheet, and a second orifice located on the second side of the first kneepad sheet. The second kneepad sheet is fixedly connected to the first kneepad sheet, and comprises a first side of a second kneepad sheet and a second side of a second kneepad sheet arranged opposite to each other. The second side of the second kneepad sheet and the first through hole form a first opening, the second orifice is the orifice of the first opening, and a passage for air flow is formed between the first opening and the first orifice. When the user wears the kneepad body and the user's knee joint is bent, the first opening corresponds to the position of the patella of the user's knee joint, and at least a portion of the second side of the second kneepad extends out of the first opening from the second opening. The present invention sets the kneepad body as a two-piece structure consisting of a first kneepad and a second kneepad attached and fixed together, and opens a first through hole on the first kneepad so that the second kneepad and the first through hole form a first opening to correspond to the position of the patella of the user's knee joint. During the bending process of the user's knee joint, the orifice of the first opening is gradually enlarged, so that at least a portion of the second kneepad protrudes out of the orifice, thereby not only reserving space for the movement of the patella, but also facilitating the ventilation of the patella, preventing stuffiness, and facilitating the removal of moisture between the kneepad body and the skin.
