Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1-6 As shown, this embodiment discloses a child head shield with a flip-up forehead shield, including a first headband adjustment part 1 and a second headband adjustment part 2 symmetrically arranged, and a main support frame 3. The main support frame 3 is connected between the first headband adjustment part 1 and the second headband adjustment part 2 and covers the outer surface of both to form a head-accommodating space. The main support frame 3 is characterized in that the front and rear ends of the main support frame 3 are respectively provided with a forehead shield 31 and a back forehead shield 32. The front and rear ends of the first headband adjustment part 1 and the second headband adjustment part 2 are each provided with a first connecting part 4. The inner surface of the forehead shield 31 and the back forehead shield 32 is provided with a second connecting part 5 that is detachably connected to the first connecting part 4. The headband can be adjusted by changing the relative connection position of the first connecting part 4 and the second connecting part 5. The second connecting part 5 is disconnected from the first connecting part 4 to allow the forehead shield 31 and the back forehead shield 32 to be flipped up and down.

[0026] The detachable design of the first connecting part 4 and the second connecting part 5 allows for free adjustment of their contact positions, changing the overlapping areas of the front and rear ends of the forehead shield 31 and the back forehead shield 32 with the first hat size adjustment part 1 and the second hat size adjustment part 2, thereby expanding or shrinking the circumferential size of the head-accommodating space and realizing stepless adjustment of the hat size to adapt to children with different head sizes.

[0027] When it is necessary to check the condition of a child's head or remove the protective gear in an emergency, force is applied in the vertical direction to separate the second connecting part 5 from the first connecting part 4. The forehead shield 31 and the back forehead shield 32 can be flipped upward to form an open state, thereby realizing the quick flipping of the shields for temporary inspection or heat dissipation.

[0028] The main support frame 3 covers the outer surface of the first hat circumference adjustment part 1 and the second hat circumference adjustment part 2, forming a ring support frame to evenly distribute the impact force. After flipping open the forehead shield 31 and the back forehead shield 32, the first hat circumference adjustment part 1 and the second hat circumference adjustment part 2 are put on the child's head. The symmetrically arranged first hat circumference adjustment part 1 and the second hat circumference adjustment part 2 move synchronously to adapt to the child's head circumference during adjustment, maintain the balance of the protective gear center of gravity, and avoid wearing deviation caused by unilateral adjustment.

[0029] In one preferred embodiment, the first connecting part 4 is a hook and loop fastener, and the second connecting part 5 is a textured surface formed on the inner surfaces of the forehead shield 31 and the back forehead shield 32, or a textured hook and loop fastener covering the inner surfaces of the forehead shield 31 and the back forehead shield 32.

[0030] The second connecting part 5 covers the inner surface contact area of ​​the forehead shield 4 and the back forehead shield 5, providing multiple bonding options and enabling millimeter-level precise adjustment of the helmet circumference size. When the shield is flipped up with upward force, the fiber claws of the hook-and-loop fasteners detach from the loop or loop-and-loop fasteners under shearing force. When the shield is closed, simply pressing the shield will restore the bonding state.

[0031] In one preferred embodiment, the first connecting part 4 is a magnetic buckle located at the front and rear ends of the first hat circumference adjustment part 1 and the second hat circumference adjustment part 2, and the second connecting part 5 is a magnetic strip embedded in the inner surface of the forehead shield 31 and the back forehead shield 32 and magnetically engaging with the magnetic buckle.

[0032] Magnetic snaps are located at the front and rear ends of the first and second hat circumference adjustment sections 1 and 2, forming adjustment points. Magnetic strips are embedded in the inner surfaces of the forehead protector 31 and the back forehead protector 32, forming surface contact with the magnetic snaps for adsorption. By aligning the magnetic snaps with different positions on the magnetic strips, a gradient adjustment of the hat circumference is achieved. When the protectors are closed, they return to their original position to restore the adsorption state without needing to be pressed. The surface of the magnetic strip can be covered with a silicone protective layer, which can be wiped clean, avoiding hygiene problems caused by dirt accumulation and decreased adhesion after sweating, as is common with traditional Velcro.

[0033] Furthermore, such as Figure 2 As shown, the inner surface of the main support frame 3 is provided with folding grooves 33 corresponding to the forehead shield 31 and the back forehead shield 32, and the extending direction of the folding grooves 33 coincides with the flipping axis of the forehead shield 31 and the back forehead shield 32.

[0034] The folding groove 33, by locally thinning the thickness of the main support frame 3, forms a low-stiffness flexible hinge area. This concentrates the deformation at the folding groove 33 during the shield's rotation, guiding the shield's rotation and improving the reliability of rapid disengagement. The extension direction of the folding groove 33 coincides with the rotation axis of the forehead shield 31 and the rear forehead shield 32, ensuring that the rotation center of the shield remains aligned with the geometric centerline of the folding groove 33 during rotation, thus avoiding deflection friction. During shield rotation, the folding groove 33 absorbs most of the bending stress, improving the bending fatigue resistance of the main support frame 3.

[0035] Furthermore, the first connecting part 4 is in the shape of a circle or a polygon and is located on the front and rear corners of the first hat circumference adjustment part 1 and the second hat circumference adjustment part 2.

[0036] The first connecting part 4 uses a circular or polygonal dot-shaped adhesive structure to bond with the second connecting part 5, which is distributed in a planar manner. No complicated tools or skills are required. The bonding can be completed by pressing lightly and the parts can be separated by tearing in the opposite direction. It is suitable for scenarios that require frequent putting on and taking off or adjusting.

[0037] Furthermore, such as Figure 2 , Figure 7 As shown, the inner surfaces of the first hat circumference adjustment part 1 and the second hat circumference adjustment part 2 are formed with protruding ribs 11 for fitting the head.

[0038] The rib 11 protrudes from the inner surface of the first hat circumference adjustment part 1 and the second hat circumference adjustment part 2, forming a through airflow channel between the head contact surface and the base of the first hat circumference adjustment part 1 and the second hat circumference adjustment part 2, which improves the ventilation and heat dissipation efficiency. The through airflow channel can deform and play a buffering role when impacted.

[0039] Furthermore, the main support frame 3 is provided with a plurality of first ventilation holes 34, the first hat circumference adjustment part 1 and the second hat circumference adjustment part 2 are provided with a plurality of second ventilation holes 12, and the inner surfaces of the first hat circumference adjustment part 1 and the second hat circumference adjustment part 2 are provided with a plurality of ventilation grooves 13 that communicate with the second ventilation holes 12.

[0040] The first vent 34 and the second vent 12 are used for ventilation and heat dissipation. Together with the ventilation groove 13, they guide the hot air flow to be discharged outward, greatly improving the ventilation and heat dissipation efficiency.

[0041] This child head protection also includes a strap 6 connected to the lower edge of the first headband adjustment part 1 and the second headband adjustment part 2 for adjusting the tightness of the fit between the two and the head.

[0042] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
