Description

Technical Field

[0001] This utility model belongs to the field of automotive interior technology, specifically relating to an adjustable car seat headrest. Background Technology

[0002] In recent years, car seat design has increasingly focused on improving driving and passenger comfort and safety. However, most existing car seat headrests have a fixed angle design, failing to meet the individualized needs of different drivers for neck and head support. This design not only limits driver comfort during long drives but may also increase driver fatigue and affect driving safety. Summary of the Invention

[0003] To address the aforementioned problems, this utility model discloses an adjustable car seat headrest with a simple structure that overcomes the limitations of existing seat headrests in terms of personalized adjustment, providing a more personalized driving experience.

[0004] To achieve the above objectives, the specific technical solution of this application is as follows:

[0005] An adjustable car seat headrest includes a headrest with two parallel connecting rods connected to its bottom. The connecting rods are inserted into the backrest and connected to it. The connecting rods have a horizontal rotating shaft, and the headrest can be adjusted around the rotating shaft to adjust its angle with the backrest. The headrest includes a main body at the rear and an auxiliary steel plate connected to the front of the main body. The middle part of the auxiliary steel plate is connected to the main body, and the two sides are separate from the main body.

[0006] Based on the above technical features, the rotating shaft is further equipped with a servo motor that sends commands through an electronic controller to drive the headrest to rotate to the required angle.

[0007] Based on the above technical features, furthermore, the servo motors of the rotating shafts of the two connecting rods are connected to the electronic controller by a synchronous controller to ensure the synchronous movement of the two rotating shafts.

[0008] Based on the above technical features, optionally, a position sensor is installed on the rotating shaft to monitor the position of the headrest in real time and feed the data back to the electronic controller to ensure that the headrest accurately reaches the set angle.

[0009] Based on the above technical features, optionally, the main body is provided with openable storage boxes on both sides for placing spices or essential oil tablets for refreshing or soothing purposes.

[0010] Based on the above technical features, preferably, the auxiliary steel flexible plate and the main body are wrapped with memory foam and a wrapping layer.

[0011] Based on the above technical features, preferably, the main body has an airbag cavity inside, which contains an airbag that will deploy in case of an emergency to protect the driver and passengers inside the vehicle.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] This application allows the headrest to be freely adjusted at multiple angles via a rotating shaft. Combined with an auxiliary steel soft plate, the curvature of the soft plate can be manually adjusted to personalize the headrest, meeting the individual needs of different drivers for neck and head support and improving driving comfort.

[0014] The addition of a storage box in this application allows users to place spices or essential oil tablets, increasing the refreshing or soothing function and preventing traffic accidents caused by driver fatigue and drowsiness during long-term driving. Attached Figure Description

[0019] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] It should be noted that the terms "upper," "lower," "left," "right," "front," and "rear" used in the following description refer to the directions shown in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Furthermore, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 As shown, an adjustable car seat headrest includes a headrest comprising a main body 1 at the rear and an auxiliary steel plate 4 connected to the front of the main body. The middle of the auxiliary steel plate 4 is connected to the main body 1, while its sides are separate from the main body. The auxiliary steel plate 4 is malleable, allowing the user to manually adjust the curvature of its sides to better suit their needs.

[0022] The bottom of the main body 1 is connected to two parallel connecting rods 2. The connecting rods 2 are inserted into the backrest and connected to the backrest. The length of the insertion is adjustable, that is, the height of the headrest is adjustable.

[0023] The connecting rod is equipped with a horizontal rotating shaft 3, and the headrest can be adjusted around the rotating shaft to change its angle relative to the backrest. Furthermore, the rotating shaft 3 is equipped with a servo motor that sends commands through an electronic controller to drive the headrest to rotate to the desired angle.

[0024] Furthermore, the servo motors of the rotating shafts 3 of the two connecting rods are connected to the electronic controller by a synchronous controller to ensure the synchronous movement of the two rotating shafts.

[0025] Optionally, a position sensor is installed on the rotating shaft 3 to monitor the position of the headrest in real time and feed the data back to the electronic controller to ensure that the headrest accurately reaches the set angle.

[0026] This application allows the headrest to be freely adjusted at multiple angles via a rotating shaft, meeting the personalized needs of different drivers for neck and head support and improving driving comfort.

[0027] Optionally, the main body 1 has openable storage boxes 5 on both sides for storing spices or essential oil tablets for refreshing or soothing purposes.

[0028] Preferably, the auxiliary steel flexible plate 4 and the main body are wrapped with memory foam and a wrapping layer. This provides soft and elastic support, reducing fatigue during long drives or rides and improving the overall riding experience.

[0029] Preferably, the main body 1 has an airbag cavity 6 inside, which contains an airbag that will deploy in case of an emergency to protect the driver and passengers inside the vehicle.

[0030] It should be noted that the accompanying drawings merely illustrate the technical concept of the present invention and should not be used to limit the scope of protection of the present invention. For those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and all such improvements and modifications fall within the scope of protection of the claims of the present invention.
