Description

Technical Field

[0001] This utility model belongs to the technical field of child safety protection products, and in particular relates to an adjustable child head protector. Background Technology

[0002] Child head bumpers are protective devices specifically designed to protect children's heads. Their core function is to absorb impact energy through soft materials, reducing the risk of head injuries to children at home or in public places caused by collisions with furniture, hard objects, or surfaces.

[0003] Traditional head protection devices often use a structure with an internal support frame. For example, Chinese utility model patent with publication number CN 222656377 U places the first and second head circumference adjustment parts on the outside of the main support frame. The first and second head circumference adjustment parts work together to adjust the head circumference of the head.

[0004] However, traditional head guards with built-in support frames are limited by internal space, making it difficult to form an effective impact force dispersion structure, and they also hinder air circulation, which can easily cause stuffiness and discomfort when worn for a long time. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an adjustable child head protection device.

[0006] The objective of this utility model can be achieved through the following technical solution: An adjustable child head protector, comprising a hat body, the hat body comprising a main support frame, a first hat circumference adjustment part and a second hat circumference adjustment part, the main support frame covering the outer surfaces of the first hat circumference adjustment part and the second hat circumference adjustment part, the first hat circumference adjustment part and the second hat circumference adjustment part being connected by a retractable elastic element for adjusting the hat circumference of the hat body, the inner surfaces of the first hat circumference adjustment part and the second hat circumference adjustment part having raised ribs and the outer surfaces having relief grooves corresponding to the raised ribs.

[0007] Preferably, the main support frame is ring-shaped and its two ends extend laterally to form anti-collision parts covering the ends of the first and second hat circumference adjustment parts, and elastic elements are connected to both ends of the first and second hat circumference adjustment parts.

[0008] Preferably, the inner surface of the main support member is provided with a flexible liner, and the elastic member is slidably disposed between the main support frame and the flexible liner.

[0009] Preferably, the elastic element is an adjustable elastic band, and the top of the main support frame has a connecting hole through which the elastic element passes.

[0010] Preferably, the main support frame is provided with a number of first ventilation holes.

[0011] Preferably, the first and second hat circumference adjustment parts are provided with a plurality of second ventilation holes, and the inner surfaces of the first and second hat circumference adjustment parts are provided with a plurality of ventilation grooves that pass through the second ventilation holes.

[0012] Preferably, the front and / or rear end protrusions of the main support frame form anti-collision protrusions.

[0013] Preferably, this adjustable child head protector also includes a Y-shaped strap, the forked end of which is connected to the lower edge of the first and second headband adjustment parts, and the confluence end of the Y-shaped strap is provided with an adjustable mechanism for adjusting the tightness of the fit between the headband and the head.

[0014] Preferably, the adjustable mechanism is at least one of the following: Velcro, snap fastener, hook and loop fastener, D-ring, snap fastener, rivet, or magnetic fastener.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. Breaking through the limitations of traditional built-in support frames, the main support frame is placed externally to form a ring frame structure, which allows the impact force to be quickly dispersed to the sides and top through the arc-shaped extension surface, avoiding local stress concentration; a buffer space is formed between the external frame and the head, combined with the flexible contact of the internal adjustment part (the gap of the convex rib support), to build a double-layer protection mechanism of "external frame dispersion - internal adjustment part energy absorption", which significantly improves the impact resistance performance.

[0017] 2. The raised ribs on the inner surface of the adjustment part provide support to the head, preventing sweat accumulation caused by flat contact while maintaining air circulation; the first vent of the main support frame, the second vent of the adjustment part, and the ventilation groove form a directional airflow channel, which uses the Venturi effect to accelerate airflow, improve ventilation and heat dissipation efficiency, and significantly improve wearing comfort.

[0023] 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.

[0024] like Figures 1-4 As shown, this embodiment discloses an adjustable child head protector, including a hat body 1. The hat body 1 includes a main support frame 11, a first hat circumference adjustment part 12, and a second hat circumference adjustment part 13. The main support frame 11 covers the outer surfaces of the first hat circumference adjustment part 12 and the second hat circumference adjustment part 13. The first hat circumference adjustment part 12 and the second hat circumference adjustment part 13 are connected by a retractable elastic member 2 for adjusting the hat circumference of the hat body 1. The inner surfaces of the first hat circumference adjustment part 12 and the second hat circumference adjustment part 13 are formed with raised ribs 121a and the outer surfaces are formed with relief grooves 121b corresponding to the raised ribs 121a.

[0025] Through the elasticity and stretching characteristics of the elastic element 2, when the child's head size changes, the first hat circumference adjustment part 12 and the second hat circumference adjustment part 13 automatically move towards or away from each other under the drive of the elastic element 2, thereby realizing the adjustment of the hat circumference (e.g., Figure 3 (As indicated by the arrow direction).

[0026] As an external frame, the main support frame 11 is used to protect the head of the hat. The impact points of the hat are mainly concentrated at the front, rear, and top of the main support frame 11. When the main support frame 11 is impacted, the external covering structure can quickly disperse and transfer the impact force, avoiding local stress concentration. The impact force is further absorbed by the first hat circumference adjustment part 12 and the second hat circumference adjustment part 13, improving the impact resistance. At the same time, the external design creates a buffer space between the main support frame 11 and the head, enhancing the energy absorption effect.

[0027] The raised rib 121a forms a support gap with the child's head, avoiding the accumulation of sweat caused by flat contact. Air forms a circulation channel inside the hat body 1 through the gap, which, together with the buffer space formed between the main support frame 11 and the head, achieves multi-dimensional ventilation and heat dissipation, so that even if worn for a long time, it is not easy to cause stuffiness and discomfort.

[0028] like Figure 3 , Figure 4As shown, in this embodiment, the main support frame 11 is annular and its two ends extend laterally to form anti-collision parts 111 covering the two ends of the first hat circumference adjustment part 12 and the second hat circumference adjustment part 13. Both ends of the first hat circumference adjustment part 12 and the second hat circumference adjustment part 13 are connected to elastic members 2.

[0029] The laterally extended anti-collision part 111 increases the impact area at the front and rear ends. The anti-collision part 111 covers both ends of the first hat circle adjustment part 12 and the second hat circle adjustment part 13 to ensure the safety of the child's forehead and back of the head. When the child's forehead and back of the head are hit, the anti-collision part 111 disperses the impact force along the main support frame 11 to the sides and top through the arc-shaped extension surface.

[0030] Furthermore, such as Figure 4 As shown, the inner surface of the main support 11 is provided with a flexible liner 3, and the elastic member 2 is slidably inserted between the main support frame 11 and the flexible liner 3.

[0031] The elastic element 2 slides within the slide formed by the flexible liner 3 and the main support frame 11. The flexible liner 3 serves as a flexible isolation layer, such as by using a lining, fabric sleeve, or silicone sheet, to prevent the elastic element 2 from directly rubbing against the child's head. The slide space restricts the elastic element to extend and retract only in the horizontal direction, preventing it from tilting during the adjustment of the hat circumference.

[0032] Furthermore, the elastic element 2 is an adjustable elastic band, and the top of the main support frame 11 is provided with a connecting hole 112, through which the elastic element 2 passes.

[0033] Based on the elastic elements 2 installed at both ends of the first hat circumference adjustment section 12 and the second hat circumference adjustment section 13, a connecting hole 112 is opened at the top of the main support frame 11 and the elastic element 2 is inserted through it. This realizes multi-point connection and cooperation between the main support frame 11 and the first hat circumference adjustment section 12 and the second hat circumference adjustment section 13, enhancing the stability of the connection. At the same time, this multi-point connection structure forms an inverted V-shaped force structure. The connecting hole 112 serves as the fulcrum for the movement of the elastic element 2, keeping the tension of the elastic elements 2 on both sides balanced. During hat circumference adjustment, the first hat circumference adjustment section 12 and the second hat circumference adjustment section 13 move synchronously.

[0034] In this embodiment, the main support frame 11 is provided with a plurality of first ventilation holes 114.

[0035] The first vent 114 serves as both the outlet for hot air inside the cap body 1 and the inlet for cold air outside, thus improving the heat dissipation of the cap body 1.

[0036] Furthermore, the first hat circumference adjustment part 12 and the second hat circumference adjustment part 13 are provided with a plurality of second ventilation holes 122, and the inner surfaces of the first hat circumference adjustment part 12 and the second hat circumference adjustment part 13 are provided with a plurality of ventilation grooves 123 that pass through the second ventilation holes 122.

[0037] Based on the first vent 114, the second vent 122 serves as the outlet for hot air inside the cap 1, further improving the heat dissipation of the cap 1. The ventilation groove 123 constructs a directional airflow path for hot air inside the cap 1 to flow out from the second vent 122, thereby improving heat dissipation efficiency.

[0038] Specifically, such as Figure 3 , Figure 4 As shown, when a child exercises, utilizing the Venturi effect, external cold air flows at high speed along the annular main support frame 11 through the first vent 114 (e.g., Figure 3 (In the direction of the arrow), negative pressure is generated at the narrow part of the ventilation groove 123. The negative pressure accelerates the extraction of the hot and humid air emitted from the head and discharges it through the second vent 122.

[0039] Furthermore, the front and / or rear end of the main support frame 11 protrudes to form anti-collision protrusions 113.

[0040] The raised structure of the anti-collision protrusion 113 prioritizes contact with hard objects upon impact, absorbing the initial impact energy through deformation. The main support frame 11 as a whole transmits the dispersed impact force to the first hat-circle adjustment part 12 and the second hat-circle adjustment part 13 on both sides. A buffer space is formed between the first hat-circle adjustment part 12, the second hat-circle adjustment part 13 and the child's head. A buffer space is also formed between the main support frame 11 and the child's head, constructing a multi-level gradient buffer protection mechanism, which greatly improves the anti-collision and buffer performance.

[0041] Furthermore, this adjustable child head protector also includes a Y-shaped strap 4, the forked end of which is connected to the lower edge of the first headband adjustment part 12 and the second headband adjustment part 13, and the converging end of the Y-shaped strap 4 is provided with an adjustable mechanism 41 for adjusting the tightness of the fit between the headband 1 and the head.

[0042] The Y-shaped strap 4 is fixed to the wearer's chin via an adjustable mechanism 41, forming a stable triangular mechanical structure. The forked ends of the Y-shaped strap 4 ensure ventilation and heat dissipation. The adjustable mechanism 41 tightens or loosens the end of the strap to adjust the vertical fit of the cap body 1, improving the safety and comfort of children wearing it.

[0043] The adjustable mechanism 41 is at least one of the following: Velcro, snap fastener, hook and loop fastener, D-ring, snap-on-daughter fastener, rivet fastener, or magnetic fastener. Velcro offers stepless adjustment to fit any head circumference; snap fasteners provide a secure lock with high tensile strength; hook and loop fasteners allow for quick opening and closing, convenient one-handed operation; D-ring fasteners offer precise, graded adjustment to prevent accidental loosening; snap-on-daughter fasteners feature a hidden design to avoid snagging; rivet fasteners provide permanent fixation and durability; and magnetic fasteners offer intelligent adsorption for safe and quick release. The adjustable mechanism 41 provides a gradient fit from low-intensity daily use to high-intensity protection, and is adjusted to suit the usage scenarios and safety needs of child head protection devices.

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 replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
