Description

Technical Field

[0001] This utility model relates to the field of automotive safety products technology, specifically to an inner liner with a ventilation module and a child safety seat. Background Technology

[0002] As living standards continue to improve, child safety seats are being used more and more widely in cars, and people are also demanding higher levels of comfort from children's products. The contact distance between the inner liner of a child safety seat and the child is relatively close. In warmer temperatures, heat can easily accumulate between the child's back and the inner liner. Current technology typically uses a fan in the inner liner to blow directly onto the child's back, waist, or buttocks to dissipate heat. However, this direct airflow method can easily cause children to catch a cold, and the inner liner lacks a heating device for use in cold weather, making its function rather limited. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides an inner liner with a ventilation module, comprising an inner liner and a ventilation module mounted on the inner liner. The inner liner has a contact area suitable for contact with a child's back, waist, or buttocks, and a non-contact area away from the contact area. The ventilation module includes a fan, an air inlet, an electronic control component, and an air outlet. The air inlet is located in the contact area, and the air outlet is located in the non-contact area. The electronic control component is electrically connected to and drives the fan to operate. The fan draws air from the air inlet to remove heat from the contact area.

[0004] Optionally, the ventilation module includes an air guide vane for guiding the air blown out by the fan to the air outlet.

[0005] Optionally, the ventilation module further includes a housing assembly, which includes an upper cover, a lower cover, and side covers located at the left and right ends. An accommodating cavity is formed between the upper cover, the lower cover, and the side covers, and the air guide vanes, the fan, and the electronic control components are all accommodated in the accommodating cavity.

[0006] Optionally, the air inlet is located on the upper cover, and the air outlet is located on the side cover.

[0007] Optionally, the upper cover is provided with an air guide ring, which is sleeved on the fan, so that a first air cavity is formed between the upper cover and the fan. The first air cavity is used for air intake. The air guide plate is inclined upward. The air guide plate, the upper cover and the side cover together form a second air cavity. The second air cavity is used for air exhaust. The first air cavity is connected to the second air cavity.

[0008] Optionally, the side cover is provided with a button, and the electronic control assembly includes a battery and a PCB board that are electrically connected to each other, and the button and the PCB board are electrically connected.

[0009] Optionally, the inner liner has a mounting groove in the middle, the mounting groove is connected to the left and right sides, and the ventilation module is installed in the mounting groove.

[0010] Optionally, the fan is a centrifugal fan, which is capable of radially dispersing airflow.

[0011] Optionally, it also includes a heating module, which includes a heating pad mounted on the inner liner, and the heating pad is electrically connected to the electronic control component.

[0012] Compared to existing technologies, the inner liner with a ventilation module in this invention:

[0013] 1. Children are more sensitive to temperature changes. In a car seat, the inner lining area is the closest to the child, and the ventilation module in the inner lining has the most obvious effect on the child's temperature.

[0014] 2. The fan is a centrifugal fan, which can create a "suction-blowing" circulating air effect in a local area. It draws air in from the child's back and blows it out diagonally upwards from both sides, which removes heat while avoiding direct airflow on the child's back.

[0015] 3. Existing seat linings come in various sizes and forms. If each lining has its own built-in ventilation and heating function, the development cycle is long and the cost is high. This application sets up a ventilation module that can work independently. The ventilation module can be installed by opening an installation slot on the lining. This allows all linings of suitable size to have ventilation and heating functions, shortening the development cycle and reducing development costs.

[0016] 4. The heating module and ventilation module are electrically connected, allowing users to use the heating pad in cold weather, thus enriching its functionality.

[0017] In addition, this utility model provides a child safety seat, including an inner liner with a ventilation module as described above.

[0018] Compared to existing technologies, the child safety seat described in this utility model and the inner liner with ventilation module described above have the same advantages over existing technologies, which will not be repeated here. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] This utility model embodiment provides an inner liner with a ventilation module, combined with Figures 1 to 8 As shown, the device includes an inner liner 1 and a ventilation module mounted on the inner liner 1. The inner liner 1 has a contact area suitable for contact with a child's back, waist, or buttocks, and a non-contact area away from the contact area. The ventilation module includes a fan 2, an air inlet 41, an electrical control component, and an air outlet 61. The air inlet 41 is located in the contact area, and the air outlet 61 is located in the non-contact area. The electrical control component is electrically connected to the fan 2 and drives the fan 2 to work. The fan 2 draws air from the air inlet 41 to remove heat from the contact area.

[0031] like Figure 3As shown, the arrow points in the direction of airflow. The inner liner 1 is a component inside the child safety seat. It typically has a layer of fabric that comes into contact with the child's skin. The contact area refers to the area corresponding to the fabric, specifically the front area of ​​the inner liner closest to the child. The non-contact areas refer to the left, right, upper, and lower areas of the inner liner furthest from the child. In this embodiment, the air inlet 41 is located in the front area of ​​the inner liner 1, which is closer to the child's back, waist, or buttocks. This location allows the air inlet 41 to draw away hot air between the child and the inner liner 1, resulting in better cooling and a more noticeable cooling effect. The air outlet 61 is located in the left and right areas of the inner liner 1, closer to the child's arms. The air diffused from the air outlet 41 can circulate the air around the child, further reducing the ambient temperature.

[0032] In other embodiments, the air outlet 61 can also be located at the top of the upper region, so that it does not blow air onto the child's head, thus removing heat and lowering the ambient temperature. Alternatively, the air outlet 61 can be located in the lower or rear region, blowing air out from the gap between the car seat and the child safety seat.

[0033] The air inlet 41 and the air outlet 61 can be connected by a ventilation duct, or the air can be diffused directly by a centrifugal fan, or the airflow can be guided by the arrangement of the built-in parts.

[0034] Optionally, the ventilation module includes an air guide vane 3, which is used to guide the air blown out by the fan 2 to the air outlet 61.

[0035] In this embodiment, there are two centrifugal fans 2, which can radially diffuse the axially drawn air to the air outlet 61. Two guide vanes 3 are also provided, each guiding the airflow direction of the two fans 2 to the air outlets 61 at the left and right ends respectively. The centrifugal fans, in conjunction with the guide vanes 3, improve the radial diffusion effect of the airflow. Furthermore, the sheet-like structure of the guide vanes 3 not only uses less material and has a lower cost and occupies less space, but also facilitates integration into other parts or housings, thus enhancing versatility.

[0036] like Figure 6 As shown, the air guide 3 includes an inclined portion 31, the two ends of which are a guide start end 311 and a guide end end 312, respectively. The two ends of the fan 2 are connected to the air inlet 41 and the guide start end 311, respectively, and the air outlet 61 is connected to the guide end end 312.

[0037] like Figure 4As shown, optionally, the ventilation module further includes a housing assembly, which includes an upper cover 4, a lower cover 5, and side covers 6 located at the left and right ends. A receiving cavity is formed between the upper cover 4, the lower cover 5, and the side covers 6, and the air guide vane 3, the fan 2, and the electronic control components are all housed within the receiving cavity. The air guide vane 3 and the lower cover 5 are integrally formed or fixedly connected. The housing assembly makes the ventilation module more integrated, protecting internal components while facilitating integrated installation. The inner wall of the housing assembly also provides a certain air guiding effect, working with the air guide vane 3 to direct airflow to the air outlet 61.

[0038] like Figure 1 As shown, optionally, the air inlet 41 is located on the upper cover 4, and the air outlet 61 is located on the side cover 6. The air inlet 41 and air outlet 61 do not need to be directly mounted on the inner liner 1, increasing modular integration and reducing the processing steps of the inner liner 1, thereby accommodating more inner liners 1 and enhancing versatility. In this embodiment, the air inlet 41 is a circular hole, and the air outlet 61 is a strip. Since the area of ​​the left and right sides of the inner liner 1 is smaller than the area of ​​the front side, a strip-shaped vent is provided to increase the ventilation area.

[0039] Optionally, the upper cover 4 is provided with an air guide ring 42, which is sleeved on the fan 2, so that a first air cavity 43 is formed between the upper cover 4 and the fan 2. The first air cavity 43 is used for air intake. The air guide 3 is inclined upward. The air guide 3, together with the edge of the upper cover 4 and the side cover 6, forms a second air cavity 52. ​​The second air cavity 52 is used for air exhaust. The first air cavity 43 is connected to the second air cavity 52.

[0040] like Figure 5 As shown, in this embodiment, the air guide ring 42 is circular, and there are two air guide rings 42, which are respectively aligned with the two fans 2. When the fans 2 are positioned and installed on the lower cover 5, and the upper cover 4 and the lower cover 5 are engaged, the air guide ring 42 is aligned with the air inlet 41 of the fans 2 and forms the first air cavity 43. This arrangement makes the air force more concentrated and reduces the air force interference between the two adjacent fans 2.

[0041] Optionally, the side cover 6 is provided with a button 62, and the electronic control assembly includes a battery 7 and a PCB board 8 that are electrically connected to each other, and the button 62 and the PCB board 8 are electrically connected.

[0042] like Figure 4 and Figure 8 As shown, in this embodiment, the side cover 6 is also provided with an external power socket, an indicator light 64, etc., and the battery 7 is placed between the two fans 2, so that it can work without an external power cord.

[0043] Optionally, the upper cover 4 and the lower cover 5 are snapped together. The lower cover 5 is provided with a first positioning post 51 and a second positioning post. The fan 2 is positioned by the first positioning post 51, and the PCB board 8 is positioned by the second positioning post.

[0044] like Figures 5 to 7 As shown, in this embodiment, after the upper cover 4 and the lower cover 5 are connected, side covers 6 are inserted into the left and right ends respectively. The side covers 6 are provided with inserts 63, which are inserted into the gap between the upper cover 4 and the lower cover 5. The inserts 63 are provided with mounting holes, and the upper cover 4 and the lower cover 5 are provided with screw posts. The installation and fixation between the housing components are achieved by screws passing through the screw posts on the upper cover 4 and the lower cover 5 and the mounting holes on the side covers 6.

[0045] like Figure 2 As shown, optionally, the inner liner 1 has a mounting groove 11 in the middle, the mounting groove 11 being interconnected on both sides, and the ventilation module is installed in the mounting groove 11. The mounting groove 11 can be provided on different models of inner liners 1 to accommodate the installation of the ventilation module, making installation more convenient and more versatile. In other embodiments, the ventilation module can also be configured to fit the shape of the inner liner 1 and be fixedly connected to the inner liner 1 to form a whole, or the ventilation module can directly cover the inner liner 1, etc.

[0046] Optionally, it also includes a heating module, which includes a heating pad 9, which is mounted on the inner liner 1, and the heating pad 9 is electrically connected to the electronic control component.

[0047] like Figure 2 As shown, in this embodiment, the heating pad 9 is equipped with a power cord, which is connected to the PCB board 8 through a wire hole on the lower cover 5, thus forming the entire ventilation module. The electronic control component can control the ventilation of the fan 2 and also control the heating of the heating pad 9. The heating pad 9 is positioned above the housing assembly, and the resulting heating effect is transferred to the child's back, making the heat conduction effect more obvious.

[0048] like Figure 8 As shown, the buttons 62 on the side cover 6 include a ventilation button 62 and a heating button 62. The ventilation button 62 is used to control the operation of the ventilation module, and the heating button 62 is used to control the operation of the heating module. These buttons are conveniently located on the side cover 6 at the left and right ends of the inner liner 1 for easy pressing.

[0049] Working principle:

[0050] The first air cavity 43 formed between the upper cover 4 and the fan 2 through the air guide ring 42 serves as the air intake area. The second air cavity 52 formed by the edges of the lower cover 5, the air guide 3, the upper cover 4 and the side cover 6 can serve as the air outlet duct. The two fans 2 draw air in from the air inlet 41 of the upper cover 4. After passing through the first air cavity 43, the two air guide 3 guides the air force generated by the two fans 2 through the second air cavity 52 to the air outlets 61 at the left and right ends respectively.

[0051] Beneficial effects:

[0052] 1. Children are more sensitive to temperature changes. In a car seat, the inner pad 1 area is the closest to the child. The ventilation module in the inner pad 1 has the most obvious effect on the child's temperature.

[0053] 2. Fan 2 is a centrifugal fan, which can create a "suction-blowing" circulating air effect in a localized area. The airflow direction is shown below. Figure 3 It draws air in from the child's back and blows it out diagonally upwards from both sides, removing heat while avoiding direct airflow onto the infant's back;

[0054] 3. Existing seat liner pads 1 come in various forms and sizes. If each liner pad 1 has a built-in ventilation and heating function that cannot be independently implemented, the development cycle is long and the cost is high. This application sets up a ventilation module that can work independently. The ventilation module can be installed by simply opening an installation slot 11 on the liner pad 1. This enables all liner pads 1 of suitable size to have ventilation and heating functions, shortening the development cycle and reducing development costs.

[0055] 4. The heating module and ventilation module are electrically connected, allowing users to use the heating pad 9 in cold weather, thus enriching the functionality.
