Description

Technical Field

[0001] This application relates to the field of automotive seat technology, specifically to an oxygen-generating headrest for an automotive seat. 。 Background Technology

[0002] With social development and technological progress, car sales have been increasing year by year, and more and more people are choosing cars as their means of transportation.

[0003] Studies have shown that an oxygen concentration of 26%-30% in the air is the optimal oxygen environment. However, the interior space of a car is limited and air circulation is not convenient, so the oxygen concentration is prone to be low. When drivers drive for long periods of time, do not stop at rest areas, go to high-altitude areas, are involved in accidents, or are not concentrating, the low oxygen content inside the car can more easily cause drowsiness, lethargy, and other driving safety hazards.

[0004] Improving the oxygen environment inside a car by installing an oxygen concentrator is an effective method. However, current in-car oxygen concentrators suffer from low efficiency, space constraints, and unsuitable locations for drivers, resulting in less than ideal practical effects. To ensure driving safety and reduce driver fatigue, drivers typically rest the back of their heads against the car seat headrest, making it the closest part of the body to their respiratory system. Furthermore, the availability of oxygen in the vehicle can improve rescue efficiency during emergencies. Current car seat headrests generally only provide support; therefore, creating a new type of headrest with oxygen-generating capabilities based on existing technology is a pressing issue that needs to be addressed.

[0047] The automotive seat oxygen-generating headrest of this embodiment has detailed quality requirements standards. For example, the position and size of the headrest must meet specific requirements, such as the length from the top of the headrest to the lower arc point should be greater than 700mm, the width of the headrest should be greater than 85mm, and the height of the headrest should meet specific requirements; in dynamic tests, the head shape movement must be less than 102mm, and the headrest and its mounting components should not be damaged when a vertical load of 890N is applied; the headrest material should have good support and energy absorption properties, with common headrest materials including memory foam and latex, which can provide good neck support and comfort; the headrest fixing method should ensure that no rigid, potentially harmful protrusions appear during a collision, and the height and position of the headrest should adapt to the needs of different drivers; the overall design of the headrest should reduce the risk of neck injury to passengers during a vehicle collision, and the spacing between the headrests should be small and not easily moved to ensure better protection during a collision; these standards aim to ensure that the front seat headrests can provide sufficient support and protection in various usage scenarios, reducing the risk of injury to passengers in vehicle collisions.

[0048] When using the oxygen-generating headrest of this car seat, first press the switch button 502 on the control panel 50 to start the exhaust fan 406 and air compressor 404. The exhaust fan 406 and air compressor 404 work together to create a pressure difference within the oxygen-enriching membrane unit 405. Oxygen from the air is drawn out by the exhaust fan 406 through the oxygen-enriching membrane unit 405 and delivered to the driver's respiratory system through the oxygen outlet 80 on the oxygen production system. The oxygen sensor detects the oxygen concentration inside the car and transmits the oxygen concentration signal to the controller. The controller then transmits the oxygen concentration signal to the display screen 501 on the control panel 50 for display. When the oxygen concentration inside the car reaches 30%, the oxygen concentration is activated. When the oxygen concentration inside the car drops below 26%, the controller stops the operation of the air compressor 404 and the exhaust fan 406, thus stopping the oxygen production process. When the oxygen concentration inside the car drops below 26%, the controller starts the air compressor 404 and the exhaust fan 406, thus starting the oxygen production process. This process is repeated to ensure that the oxygen concentration inside the car is always within the range of 26%-30%, providing the best oxygen environment for the people in the car. This ensures that users can receive timely oxygen supply when the oxygen level is low during driving, thereby effectively improving driving comfort and safety. It can also prevent moisture in the air inside the car from condensing on the windows, which would affect the visibility of the people inside the car and affect driving safety.
