The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0055] The headrests in related technologies provide lateral support for the user's head, causing the head to shift and sway laterally with vehicle movement. This problem arises because existing headrests lack structures on either side of the user's head to restrict lateral movement. As a result, especially on bumpy roads, the user's head sways from side to side with the vehicle's movement, causing discomfort.

[0056] To address the aforementioned issues, this application provides a headrest and a vehicle. The headrest, by providing a first support mechanism and a second support mechanism at both ends of its main body along a first direction, achieves lateral support and limitation for the ears on both sides of the user's head through the first and second support mechanisms, thereby reducing the left-right swaying of the user's head along the first direction.

[0057] By using a first adjustment component to rotate the first support mechanism relative to the main body and a second adjustment component to rotate the second support mechanism relative to the main body, the headrest can be adjusted in multiple dimensions according to the user's ear position, improving the headrest's flexibility and practicality. The headrest and vehicle provided in this application are described below with reference to the accompanying drawings and specific embodiments.

[0058] Reference Figures 1 to 2 This application provides a headrest, which may include a body 100, a first support mechanism 200 and a second support mechanism 300.

[0059] The body 100 has along the first direction (e.g.) Figure 1The X direction is relative to the first side 110 and the second side 120. The body 100, as the basic load-bearing structure, can be injection molded from polyurethane foam material, with internal reinforcing ribs to improve structural strength. In some embodiments, the first direction can be the width direction of the headrest.

[0060] The first support mechanism 200 may include a first support portion 210 and a first adjustment component 220. One end of the first adjustment component 220 is rotatably connected to the first side portion 110, and the other end of the first adjustment component 220 is connected to the first support portion 210. The first adjustment component 220 drives the first support portion 210 to rotate relative to the first side portion 110 so that the first support portion 210 is used to support one of the user's ears.

[0061] The second support mechanism 300 may include a second support portion 310 and a second adjustment component 320. One end of the second adjustment component 320 is rotatably connected to the second side portion 120, and the other end of the second adjustment component 320 is connected to the second support portion 310. The second adjustment component 320 drives the second support portion 310 to rotate relative to the second side portion 120 so that the second support portion 310 is used to support the user's other ear.

[0062] The first support mechanism 200 can refer to a combination device that includes a rigid support unit and an adjustment component. Specifically, it can be implemented by using a multi-segment telescopic rod in conjunction with a rotary hinge structure, which changes the spatial position of the support part through axial telescopic and rotary motion.

[0063] Rotary connection refers to a mechanical connection that allows components to rotate around a specific axis, which can be achieved by using a rotating shaft structure with bearings.

[0064] Among them, the support for the user's ear can refer to the functional structure that restricts the lateral displacement of the head through physical contact. Specifically, it can be achieved by using an arc-shaped surface structure wrapped in soft silicone, the curvature of which matches the shape of the human ear.

[0065] The second support mechanism 300 refers to an independent adjustment device that is symmetrically arranged with the first support mechanism 200. Specifically, it can be implemented by adopting a reverse mirror structure design. The first support mechanism 200 and the second support mechanism 300 form a bilateral limiting effect on the head through synchronous adjustment.

[0066] In practical implementation, when the user needs to fix their head, the first adjustment component 220 corresponding to the first side 110 of the main body 100 rotates to drive the first support part 210 to rotate and change the spatial position of the first support part 210. The second adjustment component 320 corresponding to the second side 120 of the main body 100 rotates to drive the second support part 310 to rotate and change the spatial position of the second support part 310, so that the first support part 210 and the second support part 310 are finally positioned on the outside of the two ears, so as to support the two ears and further support the user's head.

[0067] During vehicle movement, the first support 210 and the second support 310 limit the lateral head movement through physical contact. The multi-degree-of-freedom adjustment capabilities of the first adjustment component 220 and the second adjustment component 320 can adapt to different head circumferences and accommodate individual differences.

[0068] This application provides a headrest, which provides a first support mechanism 200 and a second support mechanism 300 at both ends of the main body 100 along a first direction, so as to support and limit the ears on both sides of the user's head through the first support mechanism 200 and the second support mechanism 300, thereby reducing the left and right swaying of the user's head along the first direction.

[0069] Through the rotatable connection of the first adjustment component 220 and the second adjustment component 320, the first support portion 210 and the second support portion 310 can be rotated and adjusted relative to the sides of the main body 100. This rotational adjustment mechanism allows the support portion to be adaptively adjusted according to the shape and size of the user's head, thereby providing more precise support for the user's ears.

[0070] Reference Figures 1 to 2 In some embodiments, the first adjustment assembly 220 may include a first telescopic rod 221, a first rotating shaft 222, and a first support rod 223. One end of the first telescopic rod 221 is connected to the first side portion 110, and the first telescopic rod 221 extends and retracts along a first direction. The first rotating shaft 222 is disposed at the other end of the first telescopic rod 221, and the axial direction of the first rotating shaft 222 extends along the first direction. One end of the first support rod 223 is connected to the first telescopic rod 221 through the first rotating shaft 222 and rotates about the axial direction of the first rotating shaft 222. The other end of the first support rod 223 is connected to the first support portion 210.

[0071] The axial extension and retraction of the first telescopic rod 221 provides linear displacement adjustment along the width of the headrest. The axial direction of the first rotating shaft 222 is aligned with the extension and retraction direction, forming a composite motion foundation. The rotation plane of the first support rod 223 is perpendicular to the extension and retraction direction of the first telescopic rod 221, creating a two-dimensional motion degree of freedom. The first rotating shaft 222 at the end of the first telescopic rod 221 avoids motion interference, and the axial direction of the first rotating shaft 222 is parallel to the extension and retraction direction of the first telescopic rod 221.

[0072] Specifically, when the first telescopic rod 221 extends along the first direction, it pushes the first support rod 223 to move outward as a whole. At this time, the first support rod 223 rotates axially around the first pivot 222, which changes the pitch angle of the first support part 210. The extension stroke of the first telescopic rod 221 controls the left and right position of the first support part 210 along the first direction, and the rotation angle of the first support rod 223 controls the vertical height of the first support part 210. The two work together to form a spatial positioning adjustment. The axial arrangement of the first pivot 222 makes the rotation direction and the extension direction form a spatial rectangular coordinate system. The first support part 210 can perform combined movements along two independent axes in three-dimensional space, thereby achieving precise positioning of the ear support point. This structure realizes the compound motion output of a single operating mechanism through mechanical linkage, completing multi-directional adjustment functions within a limited space.

[0073] Through the above technical solution, this application achieves multi-degree-of-freedom adjustment of the first support portion 210 relative to the first side portion 110. The first telescopic rod 221 can extend and retract along a first direction to adjust the distance between the first support portion 210 and the first side portion 110. The first support rod 223 can rotate around the first pivot 222 to adjust the angle of the first support portion 210. This multi-degree-of-freedom adjustment mechanism allows the first support portion 210 to adapt to the ear position of users of different body types, improving the applicability and comfort of the headrest. At the same time, the structure is simple and compact, facilitating manufacturing and assembly.

[0074] Reference Figures 1 to 2 In some embodiments, the first adjusting component 220 may further include a first pin 224, and a first support rod 223 is connected to a first rotating shaft 222 via the first pin 224. The axial direction of the first pin 224 is perpendicular to the axial direction of the first rotating shaft 222, and the first support rod 223 rotates about the axial direction of the first pin 224. In some embodiments, the first support rod 223 may also be a telescopic rod.

[0075] The axis of the first pin 224 is perpendicular to the axis of the first rotating shaft 222, forming a multi-directional rotation structure. When the first support rod 223 rotates around the axis of the first pin 224, its angle can be adjusted along a plane perpendicular to the axis of the first rotating shaft 222.

[0076] When the first support rod 223 adopts a telescopic rod structure, its length can extend or retract axially. The extension and retraction direction of the first support rod 223 is perpendicular to the extension and retraction direction of the first telescopic rod 221. The combination of the first pin 224 and the first rotating shaft 222 gives the first support rod 223 the freedom to rotate around two different axes, and the telescopic rod structure provides the ability to adjust the length of the first support rod 223.

[0077] Specifically, the first pin 224 connects the first support rod 223 to the first rotating shaft 222, allowing the first support rod 223 to not only rotate axially around the first rotating shaft 222 but also swing around the axis of the first pin 224, thereby adjusting the support angle in both the horizontal and vertical directions. For example, when it is necessary to accommodate the ear height of different users, the first support rod 223 can be swung around the first pin 224 to change the vertical angle, while simultaneously adjusting the length of the first support rod 223 to accommodate the ear along a second direction (such as...). Figure 1 The front and rear positions (in the Y direction) of the first support 210 are determined by the combination of multi-directional rotation and telescopic functions, which allows the first support 210 to precisely fit the ears of different users, preventing head swaying when the vehicle turns.

[0078] In some embodiments, the telescopic structure of the first support rod 223 can be achieved through a slide rail and a locking assembly. After being adjusted to the target length, the position is fixed by the locking assembly to ensure support stability.

[0079] In some embodiments, a first pin 224 may be disposed at the end of a first rotating shaft 222, with the axial direction of the first pin 224 forming a 90-degree angle with the axial direction of the first rotating shaft 222. One end of a first support rod 223 is hinged to the first rotating shaft 222 via the first pin 224, allowing the first support rod 223 to rotate freely about the axial direction of the first pin 224. Thus, the angle of the first support rod 223 can be adjusted in a plane perpendicular to the axis of the first rotating shaft 222.

[0080] Thus, through the above technical solution, this application achieves multi-directional adjustment of the first support rod 223. The first support rod 223 can rotate around the first pivot 222 and also around the first pin 224, and its length can be extended and retracted to adjust, thereby allowing the first support part 210 to flexibly adjust its position and angle. This multi-degree-of-freedom adjustment mechanism adapts to the needs of users of different body types, improving the comfort and practicality of the headrest. At the same time, the telescopic structure allows the headrest to retract into a compact state when not in use, making it easy to store and carry.

[0081] Reference Figures 1 to 2In some embodiments, the first adjustment component 220 may further include a second pin 225, which is disposed at one end of the first support rod 223 toward the first support portion 210, and is used to rotatably connect the first support portion 210 and the first support rod 223.

[0082] The axis of the second pin 225 is orthogonal to the axis of the first pin 224, forming a two-degree-of-freedom rotational structure. The end of the first support rod 223 is hinged to the first support part 210 via the second pin 225, allowing the first support part 210 to rotate in a vertical plane around the axis of the second pin 225. The telescopic function of the first support rod 223 and the rotational function of the second pin 225 work together to allow the support part to adjust its spatial position in both horizontal and vertical directions.

[0083] Specifically, when the user adjusts the length of the first support rod 223, the support part moves closer to or further away from the first telescopic rod 221 along the extension / retraction direction of the first support rod 223. When the first support rod 223 rotates around the first pin 224, the first support part 210 moves closer to or further away from the user's ear. When the first support part 210 rotates around the second pin 225, the support surface of the first support part 210 can be adjusted to fit the ear.

[0084] By superimposing three degrees of freedom of motion, the first support 210 can precisely conform to the ear curves of different users. For example, when the first support 210 contacts the auricle, its contact surface can automatically deflect at a certain angle around the second pin 225, so that the support surface forms a surface contact with the ear rather than a line contact, reducing local pressure.

[0085] Through the above technical solution, this application achieves angle adjustment of the first support part 210 relative to the first support rod 223, increasing the headrest's degree of adjustment freedom. Therefore, users can adjust the angle of the first support part 210 according to their individual needs and head shape, making it fit the ears better and improving the headrest's comfort and support effect. At the same time, this structural design is simple and easy to implement, improving the headrest's practicality.

[0086] Reference Figures 1 to 2 In some embodiments, the first side portion 110 has a first groove 111 for receiving the first support mechanism 200.

[0087] The first groove 111 is formed on the first side portion 110 of the headrest, and its inner wall contour matches the folded shape of the first support mechanism 200. Alternatively, the first groove 111 can at least accommodate the first support mechanism 200. The depth of the first groove 111 is set to fully accommodate the telescopic rod in the retracted state, the first support rod 223 in the folded state, and the first support portion 210.

[0088] Specifically, when the first support mechanism 200 is in a non-working state, the first telescopic rod 221 retracts axially to its shortest length, and the first support part 210 folds around the second pin 225 to fit against the surface of the first support rod 223. At this time, by manually pressing, the folded first support mechanism 200 is fully embedded into the inner cavity of the first groove 111.

[0089] When stowed, the outer surface of the first support mechanism 200 remains flush with the outer contour of the first side portion 110 of the headrest, effectively reducing the overall volume. When needed, the first support mechanism 200 can slide out of the first groove 111 along the first direction and gradually unfold. The structure of the first groove 111 allows the first support mechanism 200 to form an integral encapsulated structure with the headrest in the stowed state, preventing abnormal noises caused by component shaking during transportation, while maintaining the integrity of the product's appearance.

[0090] Through the above technical solution, this application constructs a dedicated storage space on the headrest body 100, so that the first support mechanism 200 can be completely hidden inside the headrest when not in use. This not only avoids the interference of exposed parts with the passenger's activity space, but also prevents accidental damage to the first support part 210 during transportation, significantly improving the portability and storage efficiency of the headrest.

[0091] Reference Figures 1 to 2 In some embodiments, the second adjustment component 320 may include a second telescopic rod 321, a second rotating shaft 322, and a second support rod 323.

[0092] One end of the second telescopic rod 321 is connected to the second side portion 120, and the second telescopic rod 321 extends and retracts along the first direction. The second rotating shaft 322 is disposed at the other end of the second telescopic rod 321, and the axial direction of the second rotating shaft 322 extends along the first direction. One end of the second support rod 323 is connected to the second telescopic rod 321 through the second rotating shaft 322 and rotates around the axial direction of the second rotating shaft 322, and the other end of the second support rod 323 is connected to the second support portion 310.

[0093] The axial extension and retraction of the second telescopic rod 321 provides linear displacement adjustment along the width of the headrest. The axial direction of the second rotating shaft 322 is aligned with the extension and retraction direction, forming a foundation for the composite motion. The rotation plane of the second support rod 323 is perpendicular to the extension and retraction direction of the second telescopic rod 321, creating a two-dimensional degree of freedom. The second rotating shaft 322 at the end of the second telescopic rod 321 avoids motion interference, and the axial direction of the second rotating shaft 322 is parallel to the extension and retraction direction of the second telescopic rod 321.

[0094] Specifically, when the second telescopic rod 321 extends along the first direction, it pushes the second support rod 323 to move outward as a whole. At this time, the second support rod 323 rotates axially around the second pivot 322, which changes the pitch angle of the second support part 310. The extension stroke of the second telescopic rod 321 controls the left and right position of the second support part 310 along the first direction, and the rotation angle of the second support rod 323 controls the vertical height of the second support part 310. The two work together to form a spatial positioning adjustment. The axial arrangement of the second pivot 322 makes the rotation direction and the extension direction form a spatial rectangular coordinate system. The second support part 310 can perform combined movements along two independent axes in three-dimensional space, thereby achieving precise positioning of the ear support point. This structure realizes the compound motion output of a single operating mechanism through mechanical linkage, completing multi-directional adjustment functions within a limited space.

[0095] Through the above technical solution, this application achieves multi-degree-of-freedom adjustment of the second support portion 310 relative to the first side portion 110. The second telescopic rod 321 can extend and retract along the first direction to adjust the distance between the second support portion 310 and the first side portion 110. The second support rod 323 can rotate around the second pivot 322 to adjust the angle of the second support portion 310. This multi-degree-of-freedom adjustment mechanism allows the second support portion 310 to adapt to the ear position of users of different body types, improving the applicability and comfort of the headrest. At the same time, the structure is simple and compact, facilitating manufacturing and assembly.

[0096] Reference Figures 1 to 2 In some embodiments, the second adjusting component 320 may further include a third pin, and the second support rod 323 is connected to the second rotating shaft 322 via the third pin. The axial direction of the third pin is perpendicular to the axial direction of the second rotating shaft 322, and the second support rod 323 rotates about the axial direction of the third pin. In some embodiments, the second support rod 323 may be a telescopic rod.

[0097] The third pin refers to the rotating component used to connect the second support rod 323 and the second rotating shaft 322. Specifically, it can be implemented by using a hinged pin with a locking structure. The unfolding angle of the second support rod 323 can be changed by rotating it.

[0098] The second support rod 323 is a telescopic rod, which is a rod-shaped component that can extend or retract along the axial direction. Specifically, it can be realized by using a multi-section nested sleeve structure with a limiting buckle. The length can be adjusted to accommodate different user head sizes.

[0099] Specifically, in the deployed state of the second support mechanism 300, the rotation plane of the third pin is orthogonal to the rotation plane of the second rotating shaft 322, giving the second support rod 323 two degrees of rotational freedom. When the second support rod 323 is in the telescopic state, its overall length can be adaptively adjusted according to the user's ear position. In the retracted state, the entire structure is stored in the second side 120 of the headrest by retracting the second telescopic rod 321.

[0100] Through the above technical solution, this application achieves precise adjustment of the lateral support angle for the user's head, resolving the technical contradiction that existing headrests cannot simultaneously provide stable support and convenient storage. The telescopic characteristics of the second support rod 323 allow it to adapt to different head circumferences, while the multi-directional adjustment capability of the third pin ensures that the ear support component is always in the optimal contact position.

[0101] Reference Figures 1 to 2 In some embodiments, the second support mechanism 300 may further include a fourth pin, which is symmetrically arranged with the second pin 225 and has the same function as the second pin 225. The fourth pin is used to rotatably connect the second support part 310 and the second support rod 323 so that the second support part 310 can rotate relative to the second support rod 323, so that the second support part 310 can better fit the user's ear, increase the contact area between the second support part 310 and the ear, and improve the user's experience of using the headrest.

[0102] Reference Figures 1 to 2 In some embodiments, the second side 120 of the headrest may also have a second groove, which is symmetrically arranged with the first groove 111. When the second support mechanism 300 is in the folded state, it can be completely stored in the second groove, avoiding the second support mechanism 300 from protruding out of the second side 120 of the headrest, thereby improving the storage capacity and space utilization of the headrest.

[0103] Reference Figures 1 to 2 In some embodiments, the headrest may also include a ventilation system. The body 100 has a receiving cavity inside, and the wall of the headrest has a plurality of ventilation holes 130 communicating with the receiving cavity. The ventilation system is disposed in the receiving cavity.

[0104] The receiving cavity extends longitudinally along the body 100 to form a through airflow channel, and the ventilation holes 130 are distributed in an array on the upper and lower surfaces of the headrest. The ventilation system can be a fan assembly. When the fan assembly is running, the negative pressure airflow generated forms a directional flow through the receiving cavity. After the outside air enters from the lower ventilation hole 130, it absorbs heat from the surface of the headrest as it flows along the receiving cavity. Finally, the airflow carrying heat is discharged from the upper ventilation hole 130, which improves the heat dissipation performance of the headrest.

[0105] In some embodiments, the headrest may also include a battery that provides power to the ventilation system to ensure its proper functioning.

[0106] Reference Figures 1 to 2 In some embodiments, the first groove 111 and / or the second groove are further provided with a charging interface 140, which can be electrically connected to the battery disposed in the receiving cavity and can be used to charge electronic devices, further enriching the functions of the headrest and improving the convenience of using the headrest.

[0107] Reference Figures 1 to 2 In some embodiments, speakers are provided in both the first support portion 210 and the second support portion 310. By providing speakers in the first support portion 210 and the second support portion 310, audio information can be transmitted when the first support portion 210 and the second support portion 310 are in contact with the user's ears. For example, the user can listen to music, novels, or conduct audio conferences through the speakers of the headrest, thus enriching the functions of the headrest and improving its practicality.

[0108] In some embodiments, the outer surface of the main body 100 is covered with memory foam, which can deform under the pressure applied by the user's head and better conform to the user's head, thereby improving the comfort of the headrest.

[0109] Reference Figures 1 to 2 In some embodiments, the headrest may further include a mounting strap 500 and an adjustment member 600. The mounting strap 500 is disposed on the body 100 and is used to secure the body 100 to the seat. The adjustment member 600 is disposed on the mounting strap 500 and is used to adjust the length of the mounting strap 500.

[0110] By incorporating the mounting strap 500, users can easily secure the headrest when using it, for example, by fixing it to the back of a seat. The adjusting component 600 allows adjustment of the length of the mounting strap 500 based on its position, thereby adjusting the tightness of the connection between the mounting strap 500 and the object being secured.

[0111] This application also provides a vehicle, which may include a headrest, as described in the embodiments of this application.

[0112] The vehicle described in this application, by using the aforementioned headrest, can effectively suppress lateral displacement of the user's head when the vehicle is turning. The adaptive adjustment function of the first support mechanism 200 and the second support mechanism 300 can match the differences in ear position of different users, improve the head fixation effect, and thus improve the user's experience of using the vehicle.

[0113] In some embodiments, the vehicle may be a gasoline-powered vehicle, or it may be a new energy vehicle, such as a pure electric vehicle (PEV / BEV), a range-extended electric vehicle (REEV), a hybrid electric vehicle (HEV), or a fuel cell electric vehicle. The vehicle may also be any vehicle equipped with a battery.

[0114] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
