Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a headrest, a seat, and a vehicle. Background Art

[0002] The headrest is a crucial component of a car seat. It provides a comfortable driving environment for passengers and protects their spines. Comfort and whiplash resistance are key design considerations.

[0003] Related technologies primarily aim to improve safety by modifying the headrest's shape, the distance between the headrest and the head, and the headrest's material hardness and thickness. However, these improvements are limited. Using mechanical structures to alter the distance between the headrest and the head to improve safety can easily take up a significant amount of internal space and be costly. Utility Model Content

[0004] In view of this, the embodiments of the present application provide a headrest, a seat, and a vehicle that can provide a comfortable posture experience while having high safety performance and are not prone to occupying the interior space of the vehicle.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a headrest, comprising:

[0007] a headrest body, the headrest body being provided with a support surface for supporting the head;

[0008] a soft support body, the soft support body being arranged on the support surface;

[0009] A support portion, the support portion being located inside the headrest body, the support portion being opposite to and spaced from the soft support body;

[0010] a transformable support body, the transformable support body being located in a gap between the support portion and the soft support body, the transformable support body being filled with a non-Newtonian fluid filler;

[0011] Wherein, when the force applied to the transformable support body is lower than a preset value, the transformable support body is a flexible support body; when the force applied to the transformable support body reaches a preset value, the transformable support body is a rigid support body.

[0012] The headrest provided in the embodiments of the present application has a soft support body on the headrest's main body, providing a soft, skin-friendly feel during normal vehicle operation. Furthermore, a transformable support body is provided within the main body of the headrest. The transformable support body is filled with a non-Newtonian fluid filler, allowing it to transition between a flexible and rigid support body based on the material properties of the non-Newtonian fluid filler.

[0013] Specifically, during normal vehicle travel, the convertible support body becomes flexible, providing a soft and comfortable support feeling for passengers. When the vehicle is rear-ended or involved in a collision, the force applied to the convertible support body can be converted from a flexible support body to a rigid support body. This rigid support body can provide support for the head as it swings backward, reducing the distance the head must continue to move backward, thereby reducing the possibility of spinal damage and improving safety.

[0014] Therefore, by providing a convertible support body within the headrest body, a more comfortable riding experience can be provided to passengers. Furthermore, as the convertible support body transforms between a flexible support body and a rigid support body, the distance between the convertible support body and the head remains unchanged, thereby reducing space requirements within the vehicle. Furthermore, in the event of a vehicle collision or rear-end collision, since the convertible support body can be converted from a flexible support body to a rigid support body, the rigid support body can provide support and protection for the head. This eliminates the need for a complex mechanical structure, helping to address the increased costs associated with mechanical structures and reducing the possibility of head support failure due to low mechanical reliability.

[0015] In a possible implementation of the present application, there are multiple transformable supports, and the multiple transformable supports are evenly distributed in the gap between the support portion and the soft support body.

[0016] In a possible implementation of the present application, it also includes an elastic support member, which is located in the gap between the support portion and the soft support body. The elastic support member can produce elastic deformation along the direction of vehicle travel. The elastic support member is used to provide support for the head when the conversion support body is a flexible support body.

[0017] In a possible implementation of the present application, the transformation support body includes a flexible shell, the non-Newtonian fluid filler is filled in the flexible shell, and at least part of the elastic support member is located in the flexible shell.

[0018] In a possible implementation of the present application, the flexible shell is provided with an arc outer wall, and the arc outer wall is used to provide a deformation space between two adjacent transformation supports.

[0019] In a possible implementation of the present application, a soft belt shell capable of accommodating the transformable support body is further included, wherein the soft belt shell has a first side wall and a second side wall opposite to each other along the traveling direction of the vehicle;

[0020] One end of the elastic support member is connected to the first side wall to abut the first side wall and the support portion, and the other end of the elastic support member is connected to the second side wall to abut the second side wall and the soft support body.

[0021] In a possible implementation of the present application, a mounting frame is further included, one end of the mounting frame is located inside the headrest body, and the support portion is arranged on the mounting frame; the other end of the mounting frame passes through the outside of the headrest body for connection to a backrest.

[0022] The supporting portion includes a protruding structure facing the soft supporting body, and a buffer gap is defined between the protruding structure and the mounting bracket.

[0023] In a possible implementation of the present application, a heating device is further included. The heating device is located in the headrest body and corresponds to the conversion support body, so as to convert the conversion support body from a hard support body to a flexible support body.

[0024] In a second aspect, an embodiment of the present application provides a seat, comprising:

[0025] The headrest in any of the above embodiments, wherein the headrest includes a mounting bracket;

[0026] The backrest and the headrest are fixed to the backrest through a mounting bracket.

[0027] In a third aspect, an embodiment of the present application provides a vehicle including a seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0048] The embodiment of the present application provides a headrest that can be applied to the seat of a vehicle. It should be noted that the vehicle in the present application can refer to a large car, a small car, a special-purpose vehicle, etc. For example, according to the vehicle model, the vehicle in the present application can be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model, or other models. For example, a vehicle is generally provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate, thereby driving the vehicle.

[0049] It should be noted that in the embodiments of this application, the type of vehicle power source is not limited. For example, for a fuel-powered vehicle, the power source may refer to a gasoline engine, a diesel engine, or other fuel-powered engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; and for a vehicle powered by other means, the power source may refer to a device that generates power.

[0050] The headrest is an important component of vehicle seats, which is related to driving and riding comfort as well as safety.

[0051] Seat whiplash performance is a key indicator of vehicle seat safety performance, primarily examining the seat's ability to protect the passenger's neck in a rear-end collision. When a vehicle is rear-ended, the passenger's body moves forward due to inertia, while the head is whipped backward. This rapid neck movement can cause serious injuries, making the headrest's support crucial.

[0052] Related technologies primarily aim to improve safety by modifying the headrest's structural shape, the distance between the headrest and the head, and the headrest's material hardness and thickness. However, these improvements are limited. Mechanical structures can be used to improve safety by reducing the distance between the headrest and the head, protecting the passenger's neck. However, these structures often occupy a significant amount of internal space, are complex, and require high reliability, leading to increased costs.

[0053] The headrest provided in the embodiments of the present application has a soft support body on the headrest's main body, providing a soft, skin-friendly feel during normal vehicle operation. Furthermore, a transformable support body is provided within the main body of the headrest. The transformable support body is filled with a non-Newtonian fluid filler, allowing it to transition between a flexible and rigid support body based on the material properties of the non-Newtonian fluid filler.

[0054] Specifically, during normal vehicle travel, the convertible support body becomes flexible, providing a soft and comfortable support feeling for passengers. When the vehicle is rear-ended or involved in a collision, the force applied to the convertible support body can be converted from a flexible support body to a rigid support body. This rigid support body can provide support for the head as it swings backward, reducing the distance the head must continue to move backward, thereby reducing the possibility of spinal damage and improving safety.

[0055] Therefore, by providing a convertible support body within the headrest body, a more comfortable riding experience can be provided to passengers. Furthermore, as the convertible support body transforms between a flexible support body and a rigid support body, the distance between the convertible support body and the head remains unchanged, thereby reducing space requirements within the vehicle. Furthermore, in the event of a vehicle collision or rear-end collision, since the convertible support body can be converted from a flexible support body to a rigid support body, the rigid support body can provide support and protection for the head. This eliminates the need for a complex mechanical structure, helping to address the increased costs associated with mechanical structures and reducing the possibility of head support failure due to low mechanical reliability.

[0056] On this basis, refer to Figure 1 The embodiment of the present application provides a headrest 100 , which may include a headrest body 110 , a soft support body 120 , a support portion 130 and a transformable support body 140 .

[0057] The headrest body 110 has a support surface 110a for supporting the head 200. The soft support body 120 is disposed on the support surface 110a. The support portion 130 is located within the headrest body 110. The support portion 130 and the soft support body 120 are opposite and spaced apart. The conversion support body 140 is located in the space between the support portion 130 and the soft support body 120. The conversion support body 140 is filled with a non-Newtonian fluid filler 142.

[0058] When the force applied to the transformable support body 140 is lower than a preset value, the transformable support body 140 is a flexible support body, and when the force applied to the transformable support body 140 reaches a preset value, the transformable support body 140 is a rigid support body.

[0059] It should be noted that the preset value can be set based on experimental data from whipping performance testing. The material of the non-Newtonian fluid filler 142 can then be selected based on the preset value, so that when the force applied to the transforming support 140 reaches the preset value, the non-Newtonian fluid filler 142 can transform in shape, thereby transforming the transforming support 140 from a flexible support into a rigid support. The specific parameters of the preset value are not limited in this application.

[0060] In the embodiment of the present application, the transformation support 140 is filled with a non-Newtonian fluid filler 142. A non-Newtonian fluid is a fluid whose viscosity is not constant but changes with stress or strain rate. When subjected to an external force, the viscosity of the non-Newtonian fluid filler 142 changes. As the external force increases, the viscosity of the non-Newtonian fluid filler 142 increases, and the fluid in the non-Newtonian fluid filler 142 becomes thicker, thereby slowing the propagation of the impact force and providing a shock-absorbing effect.

[0061] Therefore, when the conversion support body 140 is not subjected to an impact force, or the impact force it is subjected to is less than a preset value, the non-Newtonian fluid filler 142 can be in a fluid state, making the conversion support body 140 a flexible support body. During the passenger's ride, the head 200 feels relatively soft and supported, making the ride more comfortable. When the vehicle collides, the head 200 strikes the headrest body 110, causing the conversion support body 140 to be subjected to a large impact force. At this time, the impact force on the conversion support body 140 reaches the preset value, and the non-Newtonian fluid filler 142 in the conversion support body 140 can be transformed from a fluid state to a solid state at the moment of the impact. The conversion support body 140 is transformed into a rigid support body.

[0062] After the convertible support 140 is converted into a rigid support, it can, on the one hand, provide support for the head 200 that is swinging backward, preventing the head 200 from swinging further backward, thereby reducing the distance the head 200 swings backward and protecting the neck. Furthermore, the convertible support 140 can also absorb and disperse at least part of the impact energy, thereby providing a shock-absorbing effect and mitigating damage to the spine.

[0063] It should be noted that when the transformation support body 140 is no longer subjected to external force, it can gradually recover from a rigid support body to a flexible support body.

[0064] In addition, a soft support body 120 is provided on the support surface 110a of the headrest main body 110 of the embodiment of the present application. Therefore, during normal vehicle operation, the soft support body 120 provides a soft support experience for the passenger's head 200. In the event of a vehicle collision, the head 200 moves backward, first contacting the soft support body 120, and then transmitting the impact force to the conversion support body 140 through the soft support body 120. During the contact between the head 200 and the soft support body 120, the soft support body 120 protects the head 200 from hard collisions.

[0065] In some examples, the soft support body 120 may correspond to the passenger's head 200. The soft support body 120 may protrude from the surface of the headrest body 110 facing the passenger's head 200. Alternatively, the soft support body 120 may also be flush with the surface of the headrest body 110 facing the passenger's head 200, which is not limited in this embodiment.

[0066] It should be noted that the headrest 100 in the embodiment of the present application can be applied to the seat in the main driving position, the seat in the co-pilot position, and the rear seat, which is not specifically limited in the embodiment of the present application.

[0067] It should be noted that in the present embodiment, the material of the non-Newtonian fluid filler 142 is not limited; as long as it can transform the flexible support body into a rigid support body when the force applied to the transformation support body 140 reaches a predetermined value, the material of the non-Newtonian fluid filler 142 can be, for example, D3O (a polymer material formed by combining a viscose liquid and a polymer).

[0068] In some examples, the material of the headrest body 110 may be, but is not limited to, a foam material. For example, the foam material may be polyurethane foam (PU foam).

[0069] In some examples, the soft support body 120 may be, but is not limited to, soft foam plastic.

[0070] In some examples, the shape of the transformable support 140 is not limited in this embodiment. For example, the transformable support 140 can be a square structure. The transformable support 140 can fill the gap between the support portion 130 and the soft support 120. Alternatively, the transformable support 140 can also be a spherical or ellipsoidal structure.

[0071] In some embodiments of the present application, reference is made to Figure 1 and Figure 2 The number of the transformable support bodies 140 can be multiple. The multiple transformable support bodies 140 are evenly distributed in the gap between the support portion 130 and the soft support body 120.

[0072] In the embodiment of the present application, by arranging multiple transformable support bodies 140 evenly distributed in the interval between the support portion 130 and the soft support body 120, the multiple transformable support bodies 140 can be made to evenly correspond to the soft support body 120, so that when the passenger's head 200 leans back, the multiple transformable support bodies 140 can provide uniform support for the head 200, avoiding hollowness in some areas, which affects the comfort experience of the passenger.

[0073] On this basis, refer to Figure 3 In some embodiments of the present application, the headrest 100 may further include an elastic support member 150. The elastic support member 150 may be located within the gap between the support portion 130 and the soft support body 120. The elastic support member 150 may elastically deform along the direction of vehicle travel. The elastic support member 150 is used to provide support for the head 200 when the support body 140 is converted to a flexible support body.

[0074] During normal vehicle operation, the force applied to the convertible support body 140 is lower than a preset value, and the non-Newtonian fluid filler 142 within the convertible support body 140 is in a fluid state, making the convertible support body 140 flexible, thereby providing a soft and comfortable support experience for the passenger. However, at high speeds, overly soft support can provide poor support for the head 200 and neck, easily leading to neck fatigue and compromising passenger comfort. Therefore, the elastic support member 150 can enhance the support effectiveness of the headrest 100, providing support for the head 200 while maintaining a soft and comfortable feel, thus helping to alleviate passenger fatigue.

[0075] Furthermore, the elastic support member 150 can generate elastic deformation. When the head 200 is impacted and moves backward, the elastic support member 150 can provide support for the head 200 on the one hand, and can also cushion the force exerted on the head 200 through its own elastic deformation, thereby reducing damage to the spine.

[0076] It should be noted that in the embodiment of the present application, when the number of the transformable support body 140 is one, the transformable support body 140 is filled in the gap between the support portion 130 and the soft support body 120. In this case, the elastic support portion 130 can be located inside the transformable support body 140, and the non-Newtonian fluid filler 142 is filled around the elastic support portion 130.

[0077] When there are multiple transformable supports 140 , the elastic support portion 130 may be located inside the transformable support 140 or outside the elastic support member 150 , which is not specifically limited in this embodiment.

[0078] In some implementations, reference Figure 2 and Figure 3 The transformation support 140 may include a flexible shell 141 . A non-Newtonian fluid filler 142 is filled in the flexible shell 141 . At least a portion of the elastic support member 150 is located in the flexible shell 141 .

[0079] In this embodiment of the present application, a non-Newtonian fluid filler 142 is filled within a flexible shell 141. The flexible shell 141 is deformable. Therefore, when the transformable support 140 is subjected to a force from the head 200, and the force applied to the transformable support 140 is below a predetermined value, the non-Newtonian fluid filler 142 can flow freely within the flexible shell 141. The shape of the transformable support 140 can change, and the transformable support 140 can deform according to the position of the head 200 against the support, thereby providing comfortable support and cushioning for the passenger.

[0080] When the force applied to the transformation support 140 reaches a preset value, the non-Newtonian fluid filler 142 inside the transformation support 140 changes from a fluid state to a solid state. The flexible shell 141 can provide an elastic space for the non-Newtonian fluid filler 142 to change its shape.

[0081] In some implementations, reference Figure 2 and Figure 3 The flexible housing 141 is provided with an arc outer wall. The arc outer wall is used to provide a deformation space 110c between two adjacent transformation supports 140.

[0082] In the embodiment of the present application, when the force applied to the transformable support body 140 is lower than a preset value, the transformable support body 140 may be deformed by the impact force so as to cushion the impact force applied to the head 200 .

[0083] Furthermore, portions of the non-Newtonian fluid filler 142 are susceptible to expansion when switching between fluid and solid states. By providing the flexible housing 141 with a circular outer wall, a deformation space 110c is formed between the circular outer walls of two adjacent transformation supports 140. When the non-Newtonian fluid filler 142 collides, the flexible housing 141 expands and deforms toward the deformation space 110c, providing space for the non-Newtonian fluid filler 142 to transition between states.

[0084] In some implementations, reference Figure 2 and Figure 3 The headrest 100 may further include a soft belt shell 160 that can accommodate the transformable support body 140. Along the vehicle's traveling direction, the soft belt shell 160 has a first side wall 161 and a second side wall 162 that are opposite to each other.

[0085] One end of the elastic support member 150 is connected to the first side wall 161 to abut against the first side wall 161 and connected to the support portion 130 . The other end of the elastic support member 150 is connected to the second side wall 162 to abut against the second side wall 162 and connected to the soft support body 120 .

[0086] In the embodiment of the present application, the elastic support member 150 can press against the first side wall 161 and the second side wall 162 of the soft belt shell 160 and be connected to the support part 130 and the soft support body 120 respectively, so that the elastic support member 150 can have a supporting effect between the support part 130 and the soft support body 120.

[0087] The soft belt shell 160 can be used to accommodate the conversion support body 140 and the elastic support member 150. The conversion support body 140 and the elastic support member 150 can be fixed in the soft belt shell 160 and formed into a whole, and then installed in the gap between the support portion 130 and the soft support body 120, which is conducive to improving assembly efficiency.

[0088] Furthermore, the soft belt shell 160 can be used to secure the transformable support body 140. When there are multiple transformable supports 140, the soft belt shell 160 can prevent significant movement between the multiple transformable supports 140. This reduces the possibility that the transformable supports 140 will produce significant movement displacement during a collision, resulting in a lack of support from the transformable support body 140 in the corresponding area of ​​the head 200 when the head 200 impacts backward, thus affecting safety performance.

[0089] The soft belt shell 160 can also be used to fix the elastic support member 150. The elastic support member 150 is fixed to the soft belt shell 160, so that the elastic support member 150 can maintain elastic deformation along the direction of vehicle travel, thereby reducing the possibility of the elastic support member 150 being offset, causing the direction of elastic deformation to also shift, thereby affecting the support effect of the elastic support member 150.

[0090] In some examples, the flexible shell 141 of the transform support 140 can be connected to the inner wall of the soft belt shell 160. Here, connected can mean that the flexible shell 141 and the soft belt shell 160 are an integral structure, or that the flexible shell 141 and the soft belt shell 160 are connected by gluing or other structural parts.

[0091] In some examples, when there are multiple transformation supports 140, the multiple transformation supports 140 may be distributed linearly. Figure 4 , multiple transformation supports 140 can be arranged in a lateral direction (eg Figure 4 X direction) and longitudinal direction (e.g. Figure 4 The horizontal direction may refer to the width direction of the headrest body 110. The vertical direction may refer to the vertical direction of the headrest body 110.

[0092] Wherein, each transformable support body 140 may be correspondingly provided with an elastic support member 150 .

[0093] In some implementations, reference Figure 1 and Figure 2 The headrest 100 may further include a mounting bracket 170. One end of the mounting bracket 170 may be located inside the headrest body 110, and the support portion 130 is disposed on the mounting bracket 170. The other end of the mounting bracket 170 extends outside the headrest body 110 for connection to a backrest.

[0094] In the embodiment of the present application, part of the mounting frame 170 can be located in the headrest body 110. The mounting frame 170 can be used to fix the support portion 130. The other end of the mounting frame 170 can be connected to the backrest to fix the headrest 100 on the backrest.

[0095] In some examples, the support portion 130 may be a metal plate structure, so that when impacted, the support portion 130 can provide better support, reduce the displacement of the head 200 swinging backward, and reduce damage to the spine.

[0096] For example, the support portion 130 may include a raised structure 131 facing toward the soft support body 120. A buffer gap 110d may be defined between the raised structure 131 and the mounting bracket 170. When the head 200 impacts the headrest 100, exerting an impact force on the raised structure 131 toward the mounting bracket 170, the buffer gap 110d provides a smaller deformation space 110c for the raised structure 131 of the support portion 130. The raised structure 131 deforms toward the buffer gap 110d to cushion the reaction force on the head 200, thereby more effectively improving safety.

[0097] The surface of the raised structure 131 facing the soft support body 120 may be a curved surface. The first sidewall 161 of the soft belt shell 160, which is connected to the support portion 130, may also have a curved surface. The curved surface of the first sidewall 161 may match the curved surface of the raised structure 131. The surface of the second sidewall 162 facing the soft support body 120 may also be a curved surface.

[0098] In some implementations, the headrest 100 may further include a heating device, which may be located in the headrest body 110. The heating device corresponds to the transformable support 140, and is used to transform the transformable support 140 from a rigid support to a flexible support.

[0099] In the embodiments of the present application, the heating device can be used to accelerate the transition from rigid support 140 to a flexible support when the rigid support is converted.
