[0054] This utility model proposes a car headrest designed to provide a more comprehensive, comfortable and healthy riding experience. The car headrest can be used in the driver's seat or passenger seat.

[0055] Please see Figures 1 to 5 In one embodiment of this utility model, the car headrest includes a headrest assembly 100, a neck pillow assembly 200, and a frame assembly 300. The headrest assembly 100 includes a headrest portion 110 and a speaker 120 disposed within the headrest portion 110. The neck pillow assembly 200 is disposed below the headrest assembly 100. The neck pillow assembly 200 includes a neck pillow portion 210 and a massage device 220 disposed within the neck pillow portion 210. In one embodiment, the neck pillow assembly 200 includes a neck pillow portion 210 and a heating device 230 disposed within the neck pillow portion 210. In another embodiment, the neck pillow assembly 200 includes a neck pillow portion 210 and a massage device 220 and a heating device 230 disposed within the neck pillow portion 210. The headrest assembly 100 is connected to the frame assembly 300, and the frame assembly 300 includes a connecting rod 310 for connection to the car seat.

[0056] Traditional car headrests may only provide basic head support but lack consideration for neck comfort. By adding a neck pillow component 200, specifically designed for neck support, the overall comfort during travel is improved. The speaker 120 integrated into the headrest 110 can meet passengers' entertainment needs during travel, such as listening to music or audiobooks, enhancing the travel experience. It also further enhances the headrest's functionality when users experience neck massage and heat therapy, helping to alleviate fatigue during travel. For example, during breaks, users can recline their seats to enjoy neck massage and heat therapy while listening to soothing music from the headrest, improving the quality of rest. The integration of multiple functions, such as the speaker 120, massage device 220, and heating device 230, allows the car headrest to meet the diverse needs of different passengers, such as entertainment, relaxation, and fatigue relief.

[0057] The technical solution of this utility model uses the connecting rod 310 of the frame assembly 300 to adjust the product to the optimal position with the human cervical spine. A massage device 220 and / or a heating device 230 are installed inside the neck pillow. By incorporating these devices, the user's neck muscles can be relieved, blood circulation promoted, sleep quality improved, cervical spine diseases assisted in treatment, and the user experience enhanced. The headrest 110 ensures proper support for the user's head and neck during long journeys, reducing fatigue. The speaker 120 does not interfere with this support effect; on the contrary, it further enhances riding comfort. Located within the headrest 110, the speaker 120 directs sound directly to the user's ears, providing a more private auditory experience. It avoids interference from other noises in the vehicle, allowing the user to hear music or navigation voices more clearly. In addition to music playback, the speaker 120 also supports various entertainment modes, such as watching movies, TV series, or playing games. This diverse entertainment option makes long journeys or waiting times more interesting and fulfilling. When the speaker 120 works in conjunction with other speakers in the vehicle, it can create a surround sound music experience, making the user feel as if they are at a live concert; it can also help users relax their mind and body while experiencing the massage therapy function.

[0058] Specifically, the speaker 120 supports multiple audio input methods, such as Bluetooth connection and USB interface, allowing passengers to select music or audiobooks to play according to their preferences. Passengers can also personalize the speaker 120 via a mobile app or in-vehicle system, such as adjusting volume and sound effects. The massage device 220 and heating device 230 within the neck pillow help improve neck blood circulation and relieve neck muscle tension and stiffness. During the journey, passengers can adjust the angle and height of the headrest and neck pillow to find the most comfortable sitting posture. Simultaneously, the speaker 120 within the headrest can play soft music or meditation audio to help passengers relax and reduce stress and anxiety.

[0059] Reference Figure 2Furthermore, the headrest 110 includes a central headrest body 111 and two side wings 112 located on either side of the headrest body 111. Two speaker devices 120 are included, one of which is located on one side wing 112, and each side wing 112 has a corresponding sound outlet for its respective speaker device 120. Because the speaker devices 120 are located on either side of the headrest body 111, and the sound outlets are correspondingly located on the side wings 112, sound can be transmitted to the passenger's ears more accurately, providing a high-quality audio experience. By placing the speaker devices 120 on either side of the headrest body 111, sound can be more accurately directed to the passenger's ears, improving sound quality and listening experience. The design of the side wings 112 provides better head support, increasing comfort during seating. Simultaneously, the position of the speaker devices 120 and the design of the sound outlets prevent direct sound impact on the passenger's eardrums, reducing discomfort. This design reduces sound leakage and enhances privacy when passengers use the speaker 120 to play music or make calls inside the vehicle.

[0060] Reference Figure 2 and Figure 4 Furthermore, to address the problem of poor sound quality and significant external noise interference caused by the difficulty in integrating high-quality speakers into the headrest, and to improve sound quality, the headrest portion 110 also includes two mounting covers 114. Both side wings 112 protrude away from the frame assembly 300, forming first acoustic cavities 113. Sound outlets connect to the first acoustic cavities 113. A speaker 120 is disposed within one of the first acoustic cavities 113, and the mounting covers 114 seal the first acoustic cavity 113. The main purpose of the first acoustic cavity 113 is to provide a closed or semi-closed space for the speaker 120, providing a high-quality sound experience and reducing sound leakage and sound quality degradation. The mounting covers 114 effectively seal the first acoustic cavity 113, reducing sound leakage and thus improving sound quality.

[0061] Specifically, the mounting cover 114 is recessed in the opposite direction to the first acoustic cavity 113 to form a second acoustic cavity 115. The edge of the mounting cover 114 is provided with a ring-shaped pressing section 116, which abuts against the edge of the opening of the first acoustic cavity 113, so that the first acoustic cavity 113 and the second acoustic cavity 115 correspond. The design of the second acoustic cavity 115 can increase the reflection and resonance of sound before it is emitted, thereby improving the sound transmission efficiency and sound quality. The design of the pressing section 116 can effectively abut against the edge of the opening of the first acoustic cavity 113, forming a tight seal and reducing sound leakage. The design of the second acoustic cavity 115 and the pressing section 116 not only enhances the sound transmission efficiency and reduces sound leakage, but also improves the stability of the headrest 110 structure.

[0062] Specifically, to facilitate the installation of the cover 114, the headrest side wing 112 is provided with positioning posts and mounting posts. The positioning posts are designed with claws, and the mounting posts are provided with mounting screw holes. The cover 114 is pre-positioned and fixed by the positioning posts, and then secured to the mounting posts with screws, thus completing the fixing of the cover 114. At the same time, the claws further engage the cover 114, making the fixation more secure. In addition, the back of the headrest body 111 is provided with multiple wire harness slots for securing and fixing speaker wire harnesses, arranged along the routing direction of the speaker wire harnesses, to facilitate the storage and organization of the wire harnesses.

[0063] To improve comfort, the headrest assembly 100 includes a headrest cover 101 and a headrest foam 102. The headrest foam 102 covers the headrest portion 110, and the headrest cotton cover is fitted over the headrest foam 102. Both the headrest foam 102 and the headrest cotton cover have small openings to allow sound from the speakers to be transmitted.

[0064] Furthermore, to enhance user comfort, the headrest 110 also includes a slow-rebound foam 117. The headrest body 111 has a mounting groove, and the slow-rebound foam 117 is housed within this groove, with its surface flush with the groove's opening surface. The slow-rebound foam 117 possesses unique viscoelastic properties, allowing it to automatically adjust according to the shape and pressure distribution of the passenger's head, providing personalized support and improving riding comfort. The slow-rebound foam 117 has high density and elasticity, providing additional support to the headrest 110. The flush surface of the slow-rebound foam 117 with the groove's opening surface makes the headrest 110 appear cleaner and more aesthetically pleasing.

[0065] Furthermore, the vehicle headrest also includes a headrest cover assembly 400, which has a headrest area 410 and a neck pillow area 420 distributed vertically. The headrest part 110 is installed in the headrest area 410, and the neck pillow part 210 is installed in the neck pillow area 420. The frame assembly 300 is connected to the headrest cover assembly 400, and the frame assembly 300 is disposed opposite to the headrest part 110 and the neck pillow part 210.

[0066] The connection between the frame assembly 300 and the headrest cover assembly 400, and their relative arrangement with the headrest portion 110 and neck pillow portion 210, provides a robust support structure for the headrest. This design allows the headrest to remain stable under external forces, preventing it from wobbling or deforming, thereby enhancing the safety and stability of the ride. When the speaker 120 is located within the headrest portion 110 or neck pillow portion 210, this zoned design helps to better locate the sound source, allowing the sound to be transmitted more concentratedly to the passenger's ears.

[0067] Specifically, for ease of installation, both the headrest assembly 100 and the neck pillow assembly 200 are snapped into the headrest cover assembly 400. The headrest portion 110 of the headrest assembly 100 is provided with a snap-fit ​​groove, and the headrest cover assembly 400 is provided with a buckle. The headrest assembly 100 and the neck pillow assembly 200 are respectively snapped into the headrest cover assembly 400.

[0068] Reference Figure 3 Furthermore, the neck pillow assembly 200 includes a neck pillow portion 210 within which a heating device 230, a flame-retardant cotton layer 240, and a massage device 220 are sequentially arranged. The neck pillow assembly 200 is connected to the headrest cover assembly 400 via a neck pillow frame 211. The heating device 230 is configured as a graphene heating pad, and the massage device 220 is configured as an airbag massager. The flame-retardant cotton layer 240 separates the graphene heating pad and the airbag massager. The flame-retardant cotton layer 240 has excellent flame-retardant properties, effectively preventing the risk of fire caused by overheating or short circuit of the graphene heating pad. This ensures passenger safety during use; and compared to foam materials, flame-retardant cotton provides a more comfortable experience, not only meeting passengers' needs for warmth, comfort, and relaxation, but also ensuring safety and reliability in use. The flame-retardant cotton layer 240 includes a non-woven cover that wraps around the inner flame-retardant cotton.

[0069] The graphene heating pad boasts excellent thermal conductivity, rapidly and evenly distributing heat to the neck pillow area 210, providing passengers with warm and comfortable neck support. Its high energy conversion efficiency enables rapid heating at lower voltages, reducing energy consumption and carbon emissions. The airbag massager simulates human hand pressure through the inflation and deflation of airbags, providing passengers with a gentle and comfortable massage sensation. Passengers can adjust the massage intensity and mode according to their preferences and needs. By integrating components such as the graphene heating pad, flame-retardant cotton insert 240, and airbag massager, a more comprehensive, comfortable, and safer travel experience is provided. The synergistic effect of these components not only meets passengers' needs for warmth, comfort, and relaxation but also ensures safety and reliability in use.

[0070] Furthermore, the car headrest also includes a backup battery (not shown in the image), which is electrically connected to the heating device 230, the massage device 220, and the speaker device 120. The power supply uses a rechargeable lithium battery, ensuring that the headrest function can still be used for short periods even when the vehicle is off, providing continuous and stable physiotherapy and audio services to meet user needs. The backup battery reduces the car headrest's dependence on external power sources to a certain extent, improving the device's independence and portability.

[0071] This utility model also proposes a seat assembly (not shown in the figure), which includes a seat body and a vehicle headrest. The specific structure of the vehicle headrest is as described in the above embodiments. Since this seat assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0072] Reference Figure 5 The seat itself features a four-way adjustment mechanism 500, allowing the headrest to move up and down, and forward and backward to accommodate different users' heights and adjust according to their preferences. This design not only enhances seating comfort but also helps reduce neck and back fatigue caused by prolonged sitting. The four-way adjustment mechanism 500 enables the headrest to adapt to passengers of different heights, body types, and sitting postures, thus improving the seat's practicality and versatility.

[0073] Specifically, in this embodiment, the four-way adjustment mechanism 500 is electrically operated. For the sake of a compact structure, the four-way adjustment mechanism 500 includes: an adjustment rod 510 bent into a U-shape, a vertical adjustment component 520, and a front-to-back adjustment component 530. The adjustment rod 510 includes two first rod segments 511 arranged in parallel and a second rod segment 512 connecting the two first rod segments 511.

[0074] The up-and-down adjustment assembly 520 includes a first bracket 521, a first motor 523, and a first slider 527. The first bracket 521 has two first guide sleeves 522. The first motor 523 is mounted on the first bracket 521 and has a first lead screw 524. The first motor 523 is fixed to the bottom of the first bracket 521 by a washer 610 and a buffer washer 620. The end of the first lead screw 524 is rotatably fixed to the first bracket 521 by a lead screw washer 630. The first slider 527 is driven by the first lead screw 524 and can move up and down relative to the first bracket 521 along the first lead screw 524. Two first rod segments 511 are movably inserted through the two first guide sleeves 522. 22, and connected to the first slider 527; the front and rear adjustment assembly 530 includes a second bracket 531, a second motor 533, and a second slider 535. The second bracket 531 is located on the second rod segment 512; the second bracket 531 is provided with two second guide sleeves 532; the second motor 533 is located on the second bracket 531, and the second motor 533 has a second lead screw 534. The second motor 533 is fixed to the second bracket 531 by a gasket 610 and a buffer washer 620; the second slider 535 is connected to the second lead screw 534 and can move back and forth relative to the second bracket 531 along the second lead screw 534; the two ends of the connecting rod 310 are movably passed through the two second guide sleeves 532 and connected to the second slider 535.

[0075] In order to reduce the interference between the first lead screw 524 and the first support 521 during the movement and to ensure the smooth operation of the first lead screw 524, a lead screw washer 630 is provided at the end of the first lead screw 524 and can be rotatably fixed on the first support 521. During the rotation of the first lead screw 524, the lead screw washer 630 can prevent the end of the first lead screw 524 from rubbing against the first support 521.

[0076] Furthermore, the first motor 523 is mounted on the first bracket 521 via a buffer washer 620 and a gasket 610. This reduces the transmission of vibration from the first motor 523 during operation to the first bracket 521, thus reducing vibration and noise experienced by the user in the headrest. Specifically, for ease of installation, the outer ring of the buffer washer 620 has an annular groove, and the buffer washer 620 snaps into the mounting hole of the first bracket 521. Both ends of the buffer washer 620 abut against the stepped screw and the motor, respectively. Similarly, the second motor 533 is mounted on the second bracket 531 via a buffer washer 620 and a gasket 610, reducing noise during operation of the second motor 533.

[0077] When the headrest needs to be adjusted up and down, the first motor 523 drives the first lead screw 524 to rotate, which in turn moves the first slider 527. The adjusting rod 510, guided by the first guide sleeve 522, moves up and down with the slider 527. When moving back and forth, the second motor 533 on the adjusting rod 510 drives the second lead screw 534 to rotate, which in turn moves the second slider 535. The connecting rod 310 connects the headrest assembly 100 and the neck pillow assembly 200. Both ends of the connecting rod 310 are connected to the second slider 535 via the second guide sleeve 532, which guides the movement. The second slider 535 moves the connecting rod 310 back and forth, thereby moving the headrest back and forth.

[0078] The four-way adjustment mechanism 500 typically involves adjusting the seat or headrest in both vertical and forward / backward dimensions. In other embodiments, the four-way adjustment mechanism 500 can be manual. The four-way adjustment mechanism 500 is usually integrated into the seat and can be operated by the passenger via adjustment buttons or handles on the side of the seat. During adjustment, the four-way adjustment mechanism 500 adjusts the height and forward / backward position of the headrest according to the passenger's instructions to ensure optimal support for the passenger's head and neck.

[0079] Combination Figure 1 and Figure 2Furthermore, a square-shaped shielding frame 700 is provided between the connecting rod 310 of the car headrest and the four-way adjustment mechanism 500. The connecting rod 310 is inserted into the second guide sleeve 532 and connected to the four-way adjustment mechanism 500. The shielding frame 700 is provided on both the car headrest and the four-way adjustment mechanism 500. On the one hand, the main purpose of the shielding frame 700 is to protect the internal mechanical components of the four-way adjustment mechanism 500 and its connecting rod 310 from interference or damage from the external environment.
