Child seat with ventilation function

Abstract

This utility model discloses a safety seat with ventilation function, including a seat cushion and a backrest. The seat cushion has an air intake area and an air intake plate connected to the air intake area. When the air intake mechanism of the air intake area is working, the air intake on the air intake plate forms a vortex trajectory, causing the airflow to enter the air intake area in a vortex trajectory. The backrest has several exhaust holes. The airflow in the air intake area forms an upward exhaust trajectory through a transition area and is discharged horizontally through the exhaust holes. This utility model fully considers ventilation in the buttock area and cleverly designs the air intake plate to form a better airflow trajectory, thereby ensuring as much air intake as possible. Combined with horizontal exhaust, the airflow acts on the user's back, etc., fully considering the areas where the human body has the most contact with the seat, thus improving comfort through airflow.

Description

Technical Field

[0001] This utility model relates to the field of automotive and child safety seat technology, and particularly to a safety seat with ventilation function. Background Technology

[0002] In existing technologies, child safety seats have relatively poor ventilation. For both drivers and passengers, prolonged sitting causes constant compression of the buttocks, severely impacting user comfort. This is especially true for drivers, whose primary occupation is driving, as the lack of ventilation and compression can lead to various physiological injuries. Specific problems are as follows:

[0003] First, there are inherent defects in traditional seat materials;

[0004] To ensure safety and cushioning, existing child safety seats generally use cotton fabric or high-density filling, resulting in poor breathability. When children sit for long periods, heat and moisture easily accumulate in areas in close contact with the seat, such as their back and buttocks, causing discomfort and crying, and potentially triggering skin problems such as prickly heat and eczema. Especially in summer, the surface temperature of the seat in a closed car can reach over 35°C, significantly increasing the perceived temperature for children and exacerbating their irritability.

[0005] Secondly, children have special needs for ventilation due to their physiological characteristics;

[0006] Children generate 30% more heat per unit body surface area than adults, and their sweat glands are not fully developed, so they rely on passive heat dissipation. Therefore, ventilation systems need to be designed with non-direct airflow, using baffles or suction modes to guide the airflow and prevent it from blowing directly on the skin. Utility Model Content

[0007] The purpose of this invention is to provide a safety seat with ventilation function, thereby solving the above-mentioned problems.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0009] A safety seat with ventilation function includes a seat cushion and a backrest. The seat cushion is provided with an air intake area and an air intake plate connected to the air intake area. When the air intake mechanism of the air intake area is working, the air intake on the air intake plate forms a vortex trajectory trend, so that the airflow enters the air intake area in a vortex trajectory trend.

[0010] The backrest is provided with several exhaust holes. The airflow in the air intake area passes through the transition area to form an upward exhaust trajectory and is discharged horizontally through the exhaust holes.

[0011] Furthermore, the air intake mechanism is a fan, and the air inlet is a centrally symmetrical structure offset from the central axis of the fan.

[0012] Furthermore, the air inlet is provided with several air inlet tracks with different air inlet areas, and the air inlet track with a larger air inlet area is located above the central axis of the fan.

[0013] Furthermore, the air inlet includes a first air inlet and a second air inlet located at the front and rear ends of the seat cushion, wherein the air inlet area formed by the first air inlet is larger than the air inlet area formed by the second air inlet.

[0014] Furthermore, the first air inlet is located away from the backrest, and an installation cavity communicating with the air inlet area is formed below the first air inlet.

[0015] Furthermore, the transition area is provided with an air duct, and the air inlet, the air inlet area and the air duct form an airflow trajectory from top to bottom and then horizontal.

[0016] Furthermore, the air duct is divided by several partitions fixed to the transition section between the backrest and the seat cushion. The partitions are bow-shaped formed by chord cutting, and the arc segment of the bow shape is located near the bottom of the transition area.

[0017] Furthermore, several of the aforementioned vents are located in the lower middle part of the backrest.

[0018] Furthermore, an assembly plate is provided on the back, and a flexible pad with ventilation holes is laid on the outside of the assembly plate.

[0019] Furthermore, the vent holes are provided along the center point and the edge of the assembly plate.

[0020] The beneficial effects of this utility model are as follows:

[0021] In this invention, an air inlet plate is added so that the air entering through the air inlet has a certain dynamic trend. As a result, the air does not enter directly and will not produce a countercurrent effect. However, the vortex trend will introduce more air, allowing the user to feel more cool air, thereby improving the user experience; it is especially suitable for child seats.

[0022] In this invention, the airflow is diffused in a roundabout manner by using a non-direct airflow and the air-bearing cloth cover to prevent it from blowing directly on the skin and improve human comfort.

[0023] In this invention, a single fan is used to achieve ventilation at the bottom and back, which significantly reduces costs. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0030] See attached document Figure 1-3 As shown, the ventilated child safety seat in this embodiment primarily focuses on providing greater protection for the user's buttocks. Prolonged sitting can cause physiological damage and discomfort to the buttocks, and in severe cases, even require medical attention. To address these issues, the child safety seat in this embodiment includes a seat cushion 100 and a backrest 200. The seat cushion 100 has an air intake area 110 and an air intake panel 120 connected to the air intake area 110. During design, the area can be increased to create a larger ventilation area for the air intake area 110 and the air intake panel 120, allowing airflow to enter the user's buttocks. This airflow is not limited to cold air; the flowing airflow prevents the buttocks and other parts of the body in contact with the seat cushion from becoming stuffy, thus creating a comfortable experience.

[0031] In this embodiment, the air inlet plate 120 can be integrally set at the mounting shell of the seat cushion, or it can be detachably or fixedly connected to the mounting shell of the seat cushion or other positions of the seat cushion through assembly or other means.

[0032] During use, by energizing the air intake mechanism 130 of the air intake area 110, the air intake mechanism 130 rotates, causing the air intake port 121 on the air intake plate 120 to form a vortex trajectory trend, so that the airflow enters the air intake area 100 in a vortex trajectory trend. Compared with direct current, the vortex trajectory trend will increase the flow surface of the airflow, which will not only accelerate the airflow circulation at the bottom, but also form a larger airflow activity area, improving comfort.

[0033] To avoid airflow from cold or hot air coming into contact, several exhaust holes 210 are provided on the backrest 299. The airflow in the air intake area 110 forms an upward exhaust trajectory through the transition area 300 and is discharged horizontally through the exhaust holes 210.

[0034] In this embodiment, the entire airflow trajectory first enters the air intake area 100 from top to bottom, then flows through the transition area 300 to the backrest 200, and then exits horizontally through the exhaust hole 210 on the backrest 200, instead of continuing to flow directly upwards and exiting from the top. This flow trajectory allows the airflow to also act on the back, and at the same time solves the problem of poor breathability when the user's backrest is pressed against the seat for a long time.

[0035] In this embodiment, the air intake mechanism 130 is preferably a fan, and the air inlet 121 is a centrally symmetrical structure offset from the fan's central axis. Therefore, in this embodiment, the air inlet 121 and the fan are not aligned on the same center line. This offset arrangement causes the air inlet and the fan's rotation direction to be misaligned, thus creating the possibility for more airflow to enter subsequently.

[0036] In this embodiment, the air inlet 121 is provided with several air intake tracks, and the air inlet 121 is provided with several air intake tracks with different air intake areas, and the air intake track with a larger air intake area is located above the central axis of the fan. In this embodiment, a point is first selected as the center of the air inlet 121, and then several rings are set along the center. Then, by dividing the rings, several tracks are formed, and the several rings form air intake segments with different air intake areas, so that the larger air intake track is close to the center of rotation of the fan, which helps to increase the air intake volume at this point.

[0037] Furthermore, the air inlet 121 includes a first air inlet 122 and a second air inlet 123 located at the front and rear ends of the seat cushion 100. The air intake area formed by the first air inlet 122 is larger than the air intake area formed by the second air inlet 123. By setting different air inlets, airflow can be possible in multiple places on the seat cushion, avoiding stuffiness or long-term closure at the bottom, thus improving comfort.

[0038] Specifically, the first air inlet 122 is positioned away from the backrest 200, where the contact surface between the person and the seat is larger. Below the first air inlet 122, an installation cavity is formed that communicates with the air intake area 110. Seat adjustment mechanisms and structural components can be installed within this cavity, and its connection to the air intake area 110 results in a larger airflow surface at the bottom of the seat, leading to greater airflow. Subsequently, when various flexible ventilation pads, such as fiber pads, are laid on the seat cushion, there is still significant airflow at the point of contact with the body, preventing stuffiness and other issues.

[0039] To accelerate airflow between the seat cushion and backrest, the transition area 300 is equipped with an air duct 310, forming a top-to-bottom and then horizontal airflow trajectory between the air inlet 121, the air inlet area 110, and the air duct 310. This specific airflow trajectory makes the entire airflow smoother.

[0040] To ensure a secure installation and prevent blockage, the air duct 310 is divided by several partition plates 311 fixed to the transition section between the backrest 200 and the seat cushion 100. Each partition plate 311 is an arc shape formed by chord cutting, with the arcuate section of the arc positioned near the bottom of the transition area. This arrangement, with the arcuate section positioned at the bottom, prevents airflow blockage at the bottom, improving smoothness.

[0041] Preferably, a plurality of the exhaust vents 210 are disposed in the lower middle part of the backrest 200. They are located in the center, where the human body is generally in close contact with the seat cushion and backrest, while the upper part may have some gaps due to posture, thus requiring more ventilation in the lower middle part; hence, they are located here.

[0042] To facilitate the formation of a ventilation area, an exhaust vent 210 is added. A mounting plate 220 is provided at the back 200, and a flexible pad with ventilation holes is laid on the outside of the mounting plate 220. The flexible pad can be a fabric pad or the like, and it works in conjunction with the exhaust vents to complete the exhaust.

[0043] To allow for ventilation in more areas, ventilation holes 210 are provided along the center point and edges of the mounting plate 220. This ensures ventilation from the center to the edges, preventing stuffiness in the back or area near the buttocks.

[0044] In this embodiment, ventilation in the buttock area is fully considered, and the air intake plate is cleverly designed to form a better airflow trajectory, thereby ensuring that as much air as possible is introduced. Combined with horizontal exhaust, the airflow acts on the user's back and other areas, taking into full account the areas where the human body has the most contact with the seat, and thus improving comfort through airflow.

[0045] In this embodiment, several auxiliary exhaust holes can also be provided on the assembly plate 220, such as in a matrix arrangement, thereby increasing the overall exhaust efficiency.

[0046] In this embodiment, the air intake is normally located at the fan's air inlet, where the negative pressure of the fan is greatest, resulting in the best air intake and suction effect. A fabric cover is fitted above the air intake. The fabric cover has a soft interlayer of multi-mesh material in the middle; this structure prevents the air intake from being completely blocked, ensuring air intake and ventilation of the seat bottom. Even if the air intake is completely blocked, the fan can still draw air from inside the cavity to ensure ventilation for the back.

[0047] This invention is more suitable for use with chairs, and the specific effects are as follows:

[0048] Firstly, in summer, when children sit for long periods of time, the areas of their backs and buttocks that are in close contact with the seat tend to accumulate heat and moisture, which can not only cause discomfort and crying, but may also induce skin problems such as prickly heat and eczema. In addition, the surface temperature of the seats in the enclosed car can reach more than 35°C, which significantly increases the temperature felt by children and exacerbates their irritability. The breathable structure in this embodiment can significantly improve children's skin problems and irritability.

[0049] Secondly, children generate 30% more heat per unit body surface area than adults, and their sweat glands are not fully developed, so they rely on passive heat dissipation. Therefore, the non-direct-blowing ventilation system in this embodiment allows the airflow to diffuse in a roundabout way, avoiding direct airflow onto the skin.

All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
