Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an air suction and blowing structure for automotive seat backrests. Background Technology

[0002] In the field of automotive seat design, seat comfort has always been a focus for designers and manufacturers. The seat back, in particular, is directly related to the passenger's riding experience and health. With technological advancements and rising demands for quality of life, the market is placing even higher demands on the functionality of automotive seats.

[0003] Traditional car seat backrests typically offer only basic support and protection, failing to meet passengers' higher demands for comfort and health during long journeys. Especially in hot or humid environments, passengers' backs and necks are prone to sweating, leading to discomfort. To address this issue, various seat ventilation systems have emerged on the market, designed to increase airflow over the seat surface through suction or blowing, thereby keeping passengers' backs dry and comfortable.

[0004] However, most existing car seat back ventilation systems suffer from limited functionality. Specifically, these systems typically only perform either suction or blowing functions individually, rather than simultaneously. Suction draws in hot and humid air from between the passenger's back and the seat through vents on the seat back, achieving cooling and dehumidification. Blowing, on the other hand, uses a fan to blow air into the seat back and then vents it out through vents, providing a cool environment for the passenger. Because suction and blowing cannot be performed simultaneously, passengers may experience limited ventilation, failing to meet diverse needs in different environments. Furthermore, the air drawn into the seat back tends to dissipate, resulting in wasted airflow. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention aims to provide a suction and blowing structure for a car seat back to simultaneously realize the suction and blowing functions of the seat back.

[0006] To achieve the above objectives, this utility model proposes a car seat back air intake and blowing structure, including a fan, an air bag, a backrest frame, and a backrest foam covering the backrest frame. The fan and air bag are both fixed to the backrest frame. The air bag has several air intake holes on its front side, and the backrest foam has air inlets communicating with each air intake hole on its front side. The back of the air bag is connected to the fan. The backrest foam has a cavity inside to accommodate the fan, and the cavity is closed. The fan is arranged in the cavity. The upper front of the backrest foam has an air outlet communicating with the cavity, and the air outlet is located in the neck support area of ​​the backrest foam.

[0007] In the above solution, the cavity of the foamed backrest is sealed by the backrest cover, which is simple in structure and easy to assemble.

[0008] In the above solution: the front of the back cover is provided with heat dissipation holes, which helps to improve the ventilation effect.

[0009] In the above scheme: there are two air outlets, which are arranged at intervals on the left and right to ensure uniform airflow as much as possible.

[0010] In the above scheme, there are multiple air outlets arranged in an array to ensure uniform air distribution.

[0011] In the above solution: the backrest frame includes a backrest suspension, and the fan and air bag are both fixed on the backrest suspension. The structure is simple and easy to assemble.

[0012] The beneficial effects of this utility model are:

[0013] 1. The seat backrest simultaneously incorporates air intake and air blowing functions. This allows for the extraction of heat and moisture from between the passenger's back and the seat through the air intake vents, achieving cooling and dehumidification. Simultaneously, air is delivered through the air outlets, providing a cool and comfortable seating environment. This significantly improves the seat's ventilation efficiency and comfort, meeting the diverse needs of passengers in different environments. 2. Waste of airflow is reduced. Air drawn in by the fan is blown out through the air outlets for further cooling, and the air blown out through the outlets can be drawn back in through the air intake vents, forming an air circulation system. 3. The air outlets are positioned to align with the neck area, keeping that area dry and comfortable. Attached Figure Description

[0016] Figure 3 This is a cross-sectional view of the present invention.

[0017] Figure 4 This is a partial sectional view of the present invention. Detailed Implementation

[0018] like Figure 1 As shown in Figure 4, a car seat back air suction and blowing structure mainly consists of a fan 1, an air bag 2, a backrest frame 3, and a backrest foam 4 covering the backrest frame 3.

[0019] Both the fan 1 and the air bag 2 are fixed on the backrest frame 3. The front of the air bag 2 has several air intake holes 7. The front of the backrest foam 4 has air inlet holes 5 that communicate with each air intake hole 7. The back of the air bag 2 is connected to the fan 1.

[0020] The backrest foam 4 has a cavity inside for accommodating the fan 1. The cavity is closed and the fan 1 is installed in the cavity.

[0021] An air outlet 6 communicating with the cavity is provided on the upper front of the backrest foam 4. The air outlet 6 is located in the neck support area of ​​the backrest foam 4.

[0022] This structure simultaneously realizes the air intake and air blowing functions of the seat back. In this way, the air intake hole 7 can draw out the heat and moisture between the passenger's back and the seat to achieve the cooling and dehumidification effect, and the air outlet hole 6 can deliver air to provide passengers with a cool riding environment. This greatly improves the ventilation efficiency and comfort of the seat, reduces the waste of air power, and meets the diverse needs of passengers in different environments.

[0023] Ideally, the cavity of the backrest foam 4 should be sealed by the backrest cover, which is simple in structure and easy to assemble.

[0024] Ideally, the front of the back cover should have ventilation holes to improve airflow.

[0025] Ideally, there should be two air outlets 6, spaced apart on the left and right sides, to ensure even airflow.

[0026] Ideally, there should be multiple air outlets arranged in an array to ensure even air distribution.

[0027] Ideally, the backrest frame 3 includes a backrest suspension, and the fan 1 and air bag 2 are both fixed to the backrest suspension (not shown in the figure), which has a simple structure and is easy to assemble.
