Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to a headrest and its automotive seat. Background Technology

[0002] Currently, to address the issue of poor driving comfort due to low interior temperatures in cars during winter, mature heated seats have been developed, making the driver's lower limbs warmer and more comfortable.

[0003] However, as the neck and shoulders are the weakest parts of the upper body in terms of cold protection, there is currently no heating solution specifically designed for drivers' necks.

[0004] In today's automotive market, consumers are increasingly focusing on details when it comes to driving experience. Therefore, we are researching a headrest that can directly heat the driver's shoulders and neck to create a more comfortable and humanized driving experience, so as to stand out in the fierce market competition.

The pillow core has a built-in hot air mechanism, which includes a miniature fan, an air duct, and a heating component. The miniature fan is connected to the heating component through the air duct. When the miniature fan operates, it generates a directional airflow that is delivered to the heating component through the air duct and carries the heat generated by the heating component out through the air outlet to output warm air directionally to the user's neck and shoulder area.

[0010] Furthermore, the air outlet is located at the bottom of the rear cover in the vertical direction and close to the heating component.

[0011] Furthermore, from the pillowcase to the back cover, there are perforated foam, EPP, front panel and hot air mechanism arranged in sequence.

[0012] Furthermore, the miniature fan is fixed to the front panel on the side opposite to the pillowcase.

[0013] Preferably, the miniature fan is a thin brushless fan with a noise level below 30 decibels.

[0014] Furthermore, the air inlet of the air duct faces the miniature fan, and the air outlet of the air duct faces the heating component.

[0015] Optionally, the heating component generates heat in the range of 40-60°.

[0016] Optionally, the heating assembly includes a PTC ceramic plate, which is heated by an electric current to generate heat.

[0017] A second aspect of this utility model provides an automobile seat, including a seat cushion, a backrest, and a headrest.

[0027] To make the technical solutions and effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] The present invention aims to provide a headrest with a heating function that can directly heat the driver's shoulders and neck to improve the user's driving comfort in cold weather.

[0029] like Figure 1-2 As shown, the headrest includes a headrest body 1, which includes a pillowcase 11, a pillow core, and a back cover 17. The pillow core is configured as an internal space enclosed by the pillowcase 11 and the back cover 17.

[0030] The pillow core has a built-in hot air mechanism 15, which includes a miniature fan 151, an air duct 152 and a heating component 153. The miniature fan 151 is connected to the heating component 153 through the air duct 152. When the miniature fan 151 works, it forms a directional airflow that is delivered to the heating component 153 through the air duct 152.

[0031] The back cover 17 is adapted to the pillowcase 11. The back cover 17 is provided with an air outlet 171. Preferably, the air outlet 171 is located at the bottom of the back cover 17 in the vertical direction and close to the heating element 153. The miniature fan 151 operates, carrying the heat generated by the heating element 153 and outputting it from the air outlet 171 to directionally output warm air to the user's neck and shoulder area.

[0032] From the pillowcase 11 to the back cover 17, there are perforated foam 12, EPP 13, front panel 14 and hot air mechanism 15 arranged sequentially.

[0033] The miniature fan 151 is fixed to the side of the front panel 14 opposite to the pillowcase 11. In this embodiment, two miniature fans 151 are symmetrically arranged about the central axis of the front panel 14. In order to minimize noise interference during operation, the miniature fan 151 is a thin brushless fan, which uses a combination of a brushless motor and a centrifugal fan. Its noise level is below 30 decibels and its thickness is no more than 10 mm.

[0034] The air inlet of the air duct 152 faces the miniature fan 151, and the air outlet of the air duct 152 faces the heating component 153. Preferably, in this embodiment, the air duct 152 has an inverted V-shaped structure, wherein the air inlet consists of two separate openings, and the air outlet is a single opening that combines the two.

[0035] The heating element 153 generates heat in the range of 40-60°C. The heating element 153 includes a PTC ceramic plate and a wiring harness. The PTC ceramic plate is heated by an electric current to generate heat. The heating power of the PTC ceramic plate is 30W-100W.

[0036] Those skilled in the art further explain that PTC ceramic sheets have a positive temperature coefficient of resistance. When the temperature rises to the Curie point (approximately 60°C), their resistance increases exponentially, causing the current to automatically decrease to a level that maintains the temperature, forming a natural temperature limiting mechanism. This characteristic allows the system to autonomously stabilize the temperature below 60°C without external control, meeting the maximum temperature safety threshold requirements. Furthermore, for temperature controllability and adjustability, an NTC thermistor can be used as a temperature sensor to monitor the air outlet temperature in real time. The data is converted by an ADC and input to the MCU, thereby achieving controllable temperature at the air outlet. In addition, multiple preset temperature levels, such as 40 / 45 / 50 / 55°C, are linked to the in-vehicle entertainment system via a CAN bus, allowing users to select and adjust the appropriate temperature via the central control screen or physical buttons.

[0037] like Figure 3 As shown, this utility model also protects a car seat, including a seat cushion, a backrest 2 and the aforementioned headrest, wherein the headrest is detachably connected to the backrest 2 via a headrest rod 16.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
