Description

Technical Field

[0001] This utility model relates to the field of automotive safety seat technology, and in particular to a heat dissipation device, a lumbar support with the heat dissipation device, and a seat with the lumbar support. Background Technology

[0002] A child car seat is a seat specifically designed for children of different ages (or weights), installed in a car, and effectively improves children's safety while traveling. In the event of a collision or sudden deceleration, it reduces the impact force on the child and restricts their body movement to minimize injury and ensure the child's safety while traveling. In hot summer weather, children may feel uncomfortable sitting in a car seat for extended periods. Most current car seats improve comfort by incorporating ventilation systems to dissipate heat.

[0003] When infants and toddlers are seated in car seats, a lumbar support (also known as a backrest) is usually provided to offer better support for their lower back and hips. The lumbar support is typically made of flexible cushioning foam. However, when in use, the lumbar support blocks the ventilation vents of the child car seat's ventilation system, affecting heat dissipation. Since the lower back and hips are areas prone to heat dissipation, children often experience heat buildup and sweating in these areas after sitting for a while, resulting in poor comfort.

[0004] Existing technologies typically address this problem by incorporating a ventilation device within the lumbar support. For example, Chinese Invention Patent (Publication No.: CN118343035A) discloses a child seat and vehicle with intelligent temperature and humidity adjustment for all ages. The seat includes a seat body, a newborn pad, and a control unit. The newborn pad includes a lumbar support, an inner lining, and a headrest. The lumbar support includes a lumbar support body, a support block, a lumbar support heat dissipation unit, and a support layer. The lumbar support is formed as a single unit by mounting the support block, lumbar support heat dissipation unit, and support layer onto the lumbar support body. Through a fan in the lumbar support area, it can lower the temperature of the lumbar support area, preventing overheating and maintaining the comfort of the child's waist and hips.

[0005] However, the child seat and vehicle with intelligent temperature and humidity adjustment for all ages disclosed in the above-mentioned prior art have the following drawbacks: ① The lumbar support is assembled into a whole by installing the supporting block, lumbar support heat dissipation unit and support layer on the lumbar support body. That is, the ventilation device is integrated into the lumbar support instead of being an independent whole. When the ventilation device malfunctions, the repair process is cumbersome, requiring the disassembly of the entire lumbar support structure, which consumes a lot of time and effort, and may even lead to irreparable damage, requiring the replacement of the entire lumbar support. At the same time, if the user wants to replace the ventilation device inside the lumbar support, it is difficult to replace it conveniently. This greatly limits the product's flexibility of use and the convenience of later maintenance. ② When the lumbar support is connected to the seat body, its ventilation process is relatively complex. First, the fan in the lumbar support area draws air from the newborn's waist and buttocks area, expelling heat to the backrest area. Then, the fan in the backrest area draws air from the backrest area, transferring heat to the seat side wings. Finally, the fans in the seat side wings draw air from the side wings, expelling heat outside the seat. This results in low heat dissipation efficiency, and if the fan in any of these areas malfunctions, the lumbar support area will not be able to dissipate heat.

[0006] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0035] like Figure 4 and Figure 5 As shown, this utility model provides a heat dissipation device, including a heat dissipation device body 100. The heat dissipation device body 100 includes a ventilation and heat dissipation component and a mounting box 1. The ventilation and heat dissipation component includes a pair of blower fans 2, which are installed in the mounting box 1. Each blower fan 2 is provided with a first air inlet 21 and a first air outlet 22. The mounting box 1 is provided with a second air inlet 11 corresponding to the first air inlet 21 of the blower fan 2 and a second air outlet 12 corresponding to the first air outlet 22 of the blower fan 2.

A circuit board 3 electrically connected to the blower fans 2 is provided inside the mounting box 1.

[0036] Based on the above embodiments, the present invention aims to provide a heat dissipation device. The heat dissipation device body 100 is an independent heat dissipation component with an independent exhaust heat dissipation system, which can be flexibly applied to occasions requiring exhaust heat dissipation, such as lumbar support, backrest, or stroller. The heat dissipation device body 100 draws in hot air through the first air inlet 21 and the second air inlet 11, and exhausts it from the first air outlet 22 and the second air outlet 12 on the left and right sides, thereby avoiding the discomfort that may be caused by direct airflow onto the child, while providing the necessary heat dissipation effect for the child and avoiding discomfort caused by excessive temperature.

[0037] In this embodiment, compared to a regular fan, the blower fan 2 has a more compact structure and can generate a larger air volume with a lower power. Furthermore, the blower fan 2 is small in size and can be flexibly embedded into the heat dissipation device body 100 without affecting the compactness and portability of the heat dissipation device body 100.

[0038] As another preferred embodiment of this utility model, the heat dissipation device body 100 is further provided with a USB port 4, which is electrically connected to the circuit board 3.

Then, the sealing member 7 is installed into the mounting groove 61 to fix the heat dissipation device body 100 in the mounting groove 61. In this embodiment, the mounting groove 61 extends through both sides of the waist support body 6, so that when the heat dissipation device body 100 is installed into the mounting groove 61, neither the left nor right sides will obstruct the second air outlet 12.

[0044] As another preferred embodiment of this utility model, the lumbar support body 6 has a concave first arc-shaped surface 62 and a convex second arc-shaped surface 63. The first arc-shaped surface 62 is provided with a third air inlet 621 that communicates with the mounting groove 61. The position of the third air inlet 621 corresponds to the second air inlet 11 of the mounting box 1. Both the lumbar support body 6 and the sealing member 7 are made of elastic support material, and the sealing member 7 is detachably connected to the lumbar support body 6. In this embodiment, as... Figure 1 and Figure 2 As shown, the design of the second arc-shaped surface 63 allows the lumbar support body 200 to fit more closely to the seat body 300 when placed on it; the design of the first arc-shaped surface 62 provides better support for the lower back and buttocks of infants and toddlers when they sit in the seat body 300. The first arc-shaped surface 62 is provided with a third air inlet 621 corresponding to the second air inlet 11, which is used to draw in heat from the part of the infant and toddler that is in contact with the lumbar support body 200 and exhaust it into the air through the first air outlet 22 and the second air outlet 12, thereby improving heat dissipation efficiency, keeping the child cool and comfortable, and improving the comfort of the child's ride.

[0045] like Figures 1 to 5 As shown, this utility model also provides a seat, including a seat body 300, on which the lumbar support body 200 is provided. The seat body 300 has a left guard 301 and a right guard 302, and the lumbar support body 200 is in clearance fit with both the left guard 301 and the right guard 302.

[0046] Based on the above embodiments, the present invention aims to provide a seat. The lumbar support body 200 is placed on the seat body 300, and is in clearance fit with the left and right side guards 301 and 302 of the seat body 300 to facilitate ventilation and heat dissipation. This improves the reliability of ventilation and heat dissipation, making it independent of the seat body 300's ventilation system. In this embodiment, the left and right side guards 301 and 302 are located on the left and right sides of the seat body 300, forming a semi-enclosed space to prevent children from tilting to the sides or sliding out of the seat body 300 during sudden braking, steering, or other actions while the vehicle is in motion.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
