Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of accessories for child seats, and specifically to a sunshade cover structure with enhanced cooling effect.
Background Art
[0002] A child seat is an important accessory for ensuring the safety and comfort of children during movement, and is widely used in various scenarios such as automobiles, baby strollers, and outdoor breaks. In an environment where strong sunlight directly hits in summer, regardless of indoors or outdoors, the surface of the child seat rapidly heats up due to solar radiation. In particular, the temperatures of the backrest and headrest parts exposed to sunlight are likely to reach over 50°C. Therefore, when a child sits, it not only causes stuffiness, discomfort, and an increase in sweating, but there is also a risk of unpleasant symptoms on the skin due to prolonged contact with the high-temperature surface, and in extreme cases, it may even cause heatstroke, so there are relatively significant safety concerns. On the other hand, most conventional sunshade covers for child seats only adopt a single-layer or double-layer light-shielding and reflective structure, and can only passively block a part of solar radiation, and active cooling cannot be achieved. Therefore, the cooling effect is extremely limited in a high-temperature environment, and it is difficult to meet the cooling requirements in various usage scenarios.
Summary of the Invention
[0003] (1) Problems to be Solved The technical problem to be solved by the present invention is to overcome the above-mentioned technical drawbacks and provide a sunshade cover structure having a dual cooling configuration that combines passive multi-layer heat insulation and active phase change cold storage.
[0004] (2) Technical Means To solve the above problems, the technical means provided by the present invention is a sunshade cover structure with enhanced cooling effect, comprising a seat body, wherein the upper part of the seat body is folded inward to form a bag-shaped covering portion, and the inner circumference shape of the bag-shaped covering portion conforms to the contours of the headrest and the upper part of the backrest of the child seat. An outer protective layer is integrally covered on the outer periphery of the sheet body, and the sheet body is laminated and fixed inside the outer protective layer, in order from the outside to the inside, as a reflective layer, a light-shielding layer, a buffer layer, and a heat-insulating layer. A cooling pad is sewn onto the inner surface of the outer protective layer on the child seat side, and a cooling storage compartment is formed between the inside of the cooling pad and the outer protective layer, with a cooling pack contained within the cooling storage compartment. Preferably, a water-absorbing material layer is placed in contact with the inner wall of the insulated storage compartment, and the water-absorbing material layer is provided to cover the entire inner surface of the insulated storage compartment, and quickly absorbs condensation water that forms on the surface of the coolant. The cooling agent is an individually sealed phase-change cooling pack, and an opening is provided on one side of the cooling storage section, and the phase-change cooling pack is detachably housed inside the cooling storage section through the opening. Preferably, the reflective layer is one of an aluminum vapor-deposited reflective film layer, an aluminum vapor-deposited PET film layer, or a mirror-finish aluminum vapor-deposited film layer. Preferably, the light-shielding layer is one of the following: a black Oxford cloth layer, a black light-shielding cloth layer, a black polyester taffeta layer, a light-shielding coated cloth layer, or a PVC light-shielding film layer. Preferably, the buffer layer is one of the following: a closed-cell EVA foam layer, a cross-linked polyethylene foam layer (XPE), an EPDM foam layer, a polyethylene foam layer, or a flexible polyurethane foam layer. Preferably, the thermal insulation layer is one of an aerogel thermal insulation felt layer, a polyurethane foam layer, a glass wool thermal insulation layer, an aluminosilicate-based thermal insulation layer, or a polystyrene foam layer. Preferably, the exterior protective layer is one of the following: an abrasion-resistant and waterproof Oxford cloth layer, a nylon woven fabric layer, a PVC coated cloth layer, a PU coated cloth layer, or a polyester canvas layer.
[0005] (3) Beneficial effects This invention offers the following advantages compared to conventional technology. Specifically, this invention employs a multi-layer passive heat shielding structure consisting of a reflective layer, a light-shielding layer, a buffer layer, and a heat-insulating layer, and combines this with a removable phase-change cooling pack inside the cooling storage compartment to achieve double cooling. This effectively reduces the temperature of the contact area of the child seat, thus solving the problem of the seat overheating after direct sunlight in summer, and making it applicable to multiple usage scenarios. Furthermore, in this invention, the water-absorbing layer provided on the inner wall of the insulated storage compartment effectively absorbs condensation water generated on the surface of the phase-change cooling pack, preventing seepage that wets the seat or children's clothes, thereby improving comfort during use. Furthermore, this invention combines and fixes each functional layer, and by providing an abrasion-resistant and waterproof outer protective layer that covers the entire structure, delamination and wear are prevented, extending the service life. In addition, by coordinating the upper bag-shaped covering portion and the peripheral fixing and connecting members, it can be stably attached to different types and models of child seats, offering high versatility, easy installation, and achieving both practicality and durability.

In order to provide a clearer understanding of the present invention, the technical means included in the embodiments will be described clearly and completely below, with reference to the drawings relating to the embodiments of the present invention.
[0008] The sunshade cover structure with enhanced cooling effect according to the present invention comprises a sheet body 1, the upper part of which is folded inward to form a bag-shaped covering portion 2. An outer protective layer is integrally covered on the outer circumference of the sheet body 1, and the sheet body 1 is laminated and fixed inside the outer protective layer in the order of a reflective layer 3, a light-shielding layer 4, a buffer layer 5, and a heat-insulating layer 6 from the outside to the inside. Furthermore, a cooling pad 7 is sewn to the inner surface of the outer protective layer on the child seat side, a cooling storage portion 8 is formed between the inside of the cooling pad 7 and the outer protective layer, and a cooling pack is stored inside the cooling storage portion 8.
[0009] When in use, it has the following configuration. The reflective layer 3 is one of the following: an aluminum vapor-deposited reflective film layer, an aluminum vapor-deposited PET film layer, or a mirror-finish aluminum vapor-deposited film layer. The light-shielding layer 4 is one of the following: a black Oxford cloth layer, a black light-shielding cloth layer, a black polyester taffeta layer, a light-shielding coated cloth layer, or a PVC light-shielding film layer. The buffering layer 5 is one of the following: a closed-cell EVA foam layer, a cross-linked polyethylene foam layer (XPE), an EPDM foam layer, a polyethylene foam layer, or a flexible polyurethane foam layer. The insulation layer 6 is one of the following: an aerogel insulation felt layer, a polyurethane foam layer, a glass wool insulation layer, an aluminosilicate-based insulation layer, or a polystyrene foam layer. The outer protective layer is one of the following: abrasion-resistant and waterproof Oxford cloth layer, nylon woven fabric layer, PVC coated cloth layer, PU coated cloth layer, or polyester canvas layer. The inner circumference shape of the bag-shaped covering part 2 conforms to the contours of the headrest and the upper part of the backrest of the child seat, and the depth of the bag-shaped covering part is 5 to 15 cm.
[0010] In one embodiment, As shown in Figures 1 to 3, the sunshade cover structure with enhanced cooling effect comprises a seat body 1, the upper part of which is folded inward to form a bag-shaped covering portion 2, and the inner circumference shape of the bag-shaped covering portion 2 conforms to the contours of the headrest and upper backrest of the child seat. When in use, it can be placed directly over the headrest of the child seat, and initial positioning is possible, making it applicable to the headrest structures of various seats such as car child seats and stroller seats. The outer perimeter of the sheet body 1 is integrally covered with an outer protective layer, and this outer protective layer uses an abrasion-resistant and waterproof Oxford cloth layer. As a result, it has excellent tear resistance, waterproofing and UV resistance, effectively protects each functional layer inside, and is suitable for use in different environments such as outdoor sunlight and high temperatures inside a vehicle. Inside the exterior protective layer, a reflective layer 3, a light-shielding layer 4, a buffer layer 5, and a heat-insulating layer 6 are laminated and fixed in order from the outside to the inside. Each layer is integrally joined with hot-melt adhesive to form a stable multi-layer heat-shielding structure. This prevents delamination between layers due to frequent use or environmental changes. Of these, the reflective layer 3 uses an aluminum-deposited PET film layer and is positioned facing the direction of solar radiation, which allows for the reflection of more than 80% of the sun's infrared radiation and visible light, thereby reducing heat inflow from the source. The light-shielding layer 4 uses a black Oxford cloth layer to block the transmission of light rays and heat that remain unreflected. The buffer layer 5 uses a cross-linked polyethylene foam layer (XPE) which has a continuous porous closed-cell structure, so a thermal insulation layer of still air can be formed between the light-shielding layer 4 and the thermal insulation layer 6, effectively blocking heat transfer by convection and easing stress caused by thermal expansion and contraction, thereby preventing separation of each layer. The insulation layer 6 uses a polyurethane foam layer, which blocks the conduction of small amounts of residual heat to the child seat, further enhancing the insulation effect and meeting the cooling requirements of different situations. A cooling pad 7 is sewn onto the inner surface of the outer protective layer on the child seat side, and the periphery of the cooling pad 7 is sewn to the outer protective layer, thereby forming a cool storage compartment 8 inside. An absorbent material layer 9 is placed in contact with the inner wall of the insulated storage compartment 8. The absorbent material layer 9 uses a nonwoven fabric compounded with a superabsorbent resin and is provided to cover the entire inner surface of the insulated storage compartment 8. This allows for the rapid absorption of condensation water, preventing the seat from getting wet. Inside, individually sealed phase-change cooling packs are placed as coolants. After freezing, they can maintain and release a cooling effect for 4 to 6 hours, thus meeting the requirement for long-term use. Furthermore, they are detachable and replaceable, making them suitable for frequent use.
[0011] When using the product, first freeze the phase-change cooling pack in the refrigerator until it is completely solidified, then place it in the cooling storage compartment, and cover the child seat's headrest with the bag-shaped cover 2. When sunlight shines on it, the reflective layer 3 first reflects most of the solar radiation, and the remaining heat is blocked in stages by the light-shielding layer 4, buffer layer 5, and heat-insulating layer 6, so that almost no heat is transferred to the child seat. At the same time, the phase-change cooling pack in the cooling storage compartment 8 continuously releases its cooling effect, further reducing the temperature of the contact area of the child seat and creating a cool and comfortable seating environment for the child. The dew water generated on the surface of the phase change cold storage pack is effectively absorbed by the water absorption material layer 9 on the inner wall of the cold storage housing 8, so no leakage occurs. After use, the phase change cold storage pack can be taken out and frozen again to prepare for the next use, meeting the requirements of repeated use in various scenarios such as moving in a vehicle and playing outdoors.
