[0032] This utility model provides a children's backpack that can adapt to the curve of a child's back, distribute the pressure on the back, and improve comfort and breathability when the child is carrying the backpack.

[0033] like Figure 1 As shown, this utility model embodiment provides a children's backpack 100, including a backpack body 110. The back of the backpack body 110 has a fitting surface 120 for close contact with a child's back. A first massage structure 130 is provided in the middle of the fitting surface 120. The cross-section of the first massage structure 130 is butterfly-shaped. The first massage structure 130 includes a first partition 131, a first ventilation groove 132 and a second partition 133 arranged longitudinally. The first partition 131 and the second partition 133 are both protruding from the fitting surface 120. The first ventilation groove 132 extends laterally. The area of ​​the first partition 131 is larger than that of the second partition 133. The first partition 131 and the second partition 133 are filled with a polymer flexible support material.

[0034] This utility model's technical solution features a butterfly-shaped first massage structure 130 on the contact surface 120 of the backpack body 110. The first massage structure 130 includes a first section 131 and a second section 133, both protruding from the contact surface 120. The first section 131 and the second section 133 are filled with a flexible polymer support material. The first section 131 is designed to fit the latissimus dorsi muscle area of ​​a child, while the second section 133 is designed to fit the areas on both sides of the spine. This partitioned design adapts to the curve of a child's back, distributing back pressure and providing support and massage to the back when the child carries the backpack 100, improving comfort and reducing back fatigue. Furthermore, a first ventilation groove 132 is provided between the first section 131 and the second section 133, improving breathability and reducing stuffiness when the backpack 100 is in prolonged contact with the child's back.

The second partition 133 includes a third part 1331, a third ventilation groove 1332, and a fourth part 1333 arranged horizontally in sequence, with the third ventilation groove 1332 extending longitudinally. The widths of the second ventilation groove 1312 and the third ventilation groove 1332 are both greater than the width of the first ventilation groove 132. This utility model's technical solution, by separately setting the first part 1311, the second part 1313, the third part 1331, and the fourth part 1333, facilitates partitioning to fit the curve of a child's back. Furthermore, ventilation grooves are provided between adjacent parts, forming a "+" shaped ventilation structure. When the backpack 100 is in contact with the child's back for extended periods, this improves breathability and reduces stuffiness.

[0036] like Figure 1 As shown, a second massage structure 140 is also provided at the bottom of the contact surface 120. The cross-section of the second massage structure 140 is semi-circular, and the interior of the second massage structure 140 is filled with a flexible polymer support material. This utility model's technical solution, by providing a semi-circular second massage structure 140 at the bottom of the contact surface 120, facilitates a close fit to the child's lower back area, reduces spinal pressure, and provides support and massage to the lower back when the child is carrying the backpack 100, improving comfort and reducing lower back fatigue.

[0037] Preferably, the polymeric flexible support material includes one of slow-rebound sponge, EVA material, and thermoplastic elastomer. The polymeric flexible support material can softly conform to the back and waist, and adapt to the child's movements (e.g., when bending over, the massage structure bends synchronously to maintain a close fit).

[0038] like Figure 1As shown, the second massage structure 140 includes a fifth part 141, a fourth ventilation groove 142, and a sixth part 143 arranged horizontally in sequence. Both the fifth part 141 and the sixth part 143 protrude from the contact surface 120. The fourth ventilation groove 142 extends longitudinally, and its width is greater than that of the first ventilation groove 132. This invention, by providing the fifth part 141 and the sixth part 143, facilitates zoned contact with different areas of the child's lower back. Furthermore, the fourth ventilation groove 142 between the fifth part 141 and the sixth part 143 improves breathability and reduces stuffiness when the backpack 100 is in prolonged contact with the child's waist.

[0039] In one embodiment, the width of the first venting groove 132 is 1 cm, and the widths of the second venting groove 1312, the third venting groove 1332, and the fourth venting groove 142 are 3 cm. Those skilled in the art can also determine the width of each venting groove according to actual needs, and this application does not limit the size of each venting groove.

[0040] like Figure 2 As shown, in one embodiment, the first massage structure 130 and / or the second massage structure 140 includes a hook and loop fastener (not shown) on the side near the bonding surface 120. The bonding surface 120 is provided with a hook and loop fastener surface S1, which is correspondingly arranged with the hook and loop fastener surface and can be adhered to each other, so that the first massage structure 130 and / or the second massage structure 140 can be detachably connected to the bonding surface 120. This utility model provides a hook and loop fastener on the side of the first massage structure 130 and / or the second massage structure 140 near the bonding surface 120, and a hook and loop fastener surface S1 on the bonding surface 120. Pressing allows for adhesion, and tearing allows for separation. This facilitates the detachable connection of the first massage structure 130 and / or the second massage structure 140 to the bonding surface 120, making it easy to replace the first massage structure 130 and / or the second massage structure 140 with different firmness levels, and also facilitating disassembly and cleaning. Furthermore, the hook and loop fastener is child-friendly and easy to replace.

[0041] It is understood that the hook and loop fastener surface and the hook and loop tack surface S1 can match the shape and size of the first massage structure 130 and / or the second massage structure 140, or they can be disposed only on the outer contour of the first massage structure 130 and / or the second massage structure 140, or only in the middle region of the first massage structure 130 and / or the second massage structure 140. This application does not limit the size, shape, and placement of the hook and loop fastener surface and the hook and loop tack surface S1. Those skilled in the art can determine the size, shape, and placement of the hook and loop fastener surface and the hook and loop tack surface S1 according to actual needs.

[0042] like Figure 3As shown, in another embodiment, the first massage structure 130 and / or the second massage structure 140 includes a first magnetic attraction structure (not shown in the figure) on the side near the contact surface 120, and the contact surface 120 is provided with a second magnetic attraction structure S2. The first magnetic attraction structure and the second magnetic attraction structure S2 are correspondingly arranged and can be attracted and connected to each other, so that the first massage structure 130 and / or the second massage structure 140 can be detachably connected to the contact surface 120. This utility model's technical solution, by providing a first magnetic attraction structure on the side of the first massage structure 130 and / or the second massage structure 140 near the contact surface 120 and providing a second magnetic attraction structure S2 on the contact surface 120, facilitates the quick detachment and connection of the first massage structure 130 and / or the second massage structure 140 to the contact surface 120, facilitates the replacement of the first massage structure 130 and / or the second massage structure 140 with different hardness, and also facilitates disassembly and cleaning.

[0043] Specifically, in hot weather such as summer, a thinner first massage structure 130 and / or second massage structure 140 can be selected to connect to the backpack body 110; in cold weather such as winter, a thicker first massage structure 130 and / or second massage structure 140 can be selected to connect to the backpack body 110. When carrying the backpack 100 for extended periods, a lighter material (such as EVA material) can be selected for the first massage structure 130 and / or second massage structure 140.

[0044] Furthermore, the first massage structure 130 and / or the second massage structure 140 are also provided with an elastic protective portion (not shown in the attached drawings), which wraps around and covers the exterior of the flexible polymer support material, such as... Figure 1 As shown, both the elastic protective part and the surface of the ventilation groove include multiple arrayed ventilation holes S3. This utility model's technical solution, by wrapping an elastic protective part around the first massage structure 130 and / or the second massage structure 140, and providing arrayed ventilation holes S3 on the surface of the elastic protective part and the ventilation groove, facilitates accelerated air convection on the back, improves breathability, and reduces stuffiness. Furthermore, the surface of the elastic protective part can also be provided with a wavy texture, which further enhances anti-slip properties and breathability. Specifically, the elastic protective part can be an elastic mesh fabric or a spacer fabric woven from multiple layers of fiber materials, forming a breathable structure in the middle.

[0045] like Figure 1 As shown, the outer side of the backpack body 110 also includes a solar power module 150, such as... Figure 2 as well as Figures 4 to 5As shown, a heating element 160 is further provided between the first massage structure 130 and / or the second massage structure 140 and the contact surface 120. The heating element 160 is electrically connected to the solar power module 150. The first massage structure 130 and the second massage structure 140 also include a heat-conducting layer S4, which can transfer the heat generated by the heating element 160 to the first massage structure 130 and / or the second massage structure 140. This utility model provides a heat therapy function for the back and / or waist by setting a solar power module 150 on the outside of the backpack body 110, sandwiching a heating element 160 between the first massage structure 130 and / or the second massage structure 140 and the contact surface 120, and transferring heat through the heat-conducting layer S4, which helps to save resources.

[0046] Specifically, the solar power module 150 is integrated into the top of the backpack body 110 for easy access to sunlight. The heating element 160 is a flexible and bendable graphene heating sheet, and the thermal conductive layer S4 is a silicone thermal conductive layer, which can adhere to the elastic protective part and conduct heat.

[0047] Furthermore, the backpack body 110 can also be equipped with temperature sensors that are electrically connected to the heating element 160 and the solar power module 150 respectively. The temperature sensors can monitor the temperature of the heating element 160 in real time and feed it back to the solar power module 150, thereby adjusting the temperature and helping to avoid burns.

[0048] like Figure 6 As shown, in one embodiment, the surfaces of the first massage structure 130 and / or the second massage structure 140 are provided with hemispherical massage protrusions S5. This invention, by providing hemispherical massage protrusions S5 on the surfaces of the first massage structure 130 and / or the second massage structure 140, provides micro-massage to the back and waist when carrying a child, which helps relieve muscle fatigue and improves comfort. Specifically, the massage protrusions S5 can be made of silicone. The massage protrusions S5 can be directly disposed on the surface of the elastic protective portion of the first massage structure 130 and / or the second massage structure 140, or the elastic protective portion can be used to wrap around the massage protrusions S5.

[0049] Furthermore, the backpack body 110 also includes shoulder straps 170 and a waist belt (not shown in the attached diagram). When a child carries the backpack 100, the shoulder straps 170 go around the child's shoulders and the waist belt goes around the child's waist, which helps to relieve back pressure. The shoulder straps 170 and the waist belt are connected to the backpack body 110 by an adjustment buckle, which allows the length of the shoulder straps 170 and the waist belt to be flexibly adjusted according to individual needs to ensure the comfort of the child wearing the backpack 100.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
