Description

Technical Field

[0001] This application relates to the field of automotive technology, specifically to an automotive seat and an automotive vehicle. Background Technology

[0002] Currently, to enhance the user experience, car seats are typically equipped with massage functions to alleviate driving fatigue. In related technologies, car seat massage functions usually employ air bags or mechanical massage heads. Air bag massage primarily uses the inflation and deflation of air bags to massage the back, while mechanical massage heads use tapping and kneading motions to massage the back.

[0003] However, current mechanical massage heads require foam between the massage head and the backrest during massage, which may cause the foam to deform excessively and become damaged. Utility Model Content

[0004] This application provides a car seat and a car, which aims to solve the above-mentioned technical problems.

[0005] In a first aspect, this application provides an automobile seat, comprising:

[0006] Backrest foam, the backrest foam has through grooves that penetrate at least two sides of the backrest foam;

[0007] The massage device is located on the side of the backrest foam away from the human body. The massage device includes a drive mechanism and a massage head. The drive mechanism is used to drive the massage head to move.

[0008] The projection shape of the groove perpendicular to the foam surface of the backrest is linear, and during the massage process of the massage device, the massage head extends at least partially out of the groove.

[0009] In some embodiments, the drive mechanism includes a drive assembly and a massage arm;

[0010] The massage head is mounted on the massage arm, and the drive assembly is used to at least drive the massage arm to rotate.

[0011] During the rotation of the massage arm, the radius corresponding to the rotation trajectory of the massage head is less than or equal to the length of the through groove along the linear shape extension direction.

[0012] In some embodiments, the massage arm has a first rotational position and a second rotational position;

[0013] When the massage arm is in the first rotating position, the massage head extends at least partially out of the through groove and can contact the back of the human body;

[0014] When the massage arm is in the second rotation position, the massage head is located on the side of the backrest foam away from the body.

[0015] In some embodiments, the massage arm further has a first swing position and a second swing position, and the massage arm can swing back and forth between the first swing position and the second swing position.

[0016] In some embodiments, when the massage arm is in a first swing position or a second swing position, there is a gap between the massage arm and / or the massage head and the backrest foam.

[0017] In some embodiments, when the massage arm is in a first swing position or a second swing position, the massage arm and / or massage head compress the backrest foam.

[0018] In some embodiments, the backrest foam is fitted with protective components;

[0019] The protective element is in contact with at least a portion of the inner wall surface of the channel; and / or, the protective element covers at least a portion of the edge of the channel opening.

[0020] In some embodiments, the through slot extends along a first direction;

[0021] The protective component fits against the inner wall surface of the through groove parallel to the first direction, and the protective component covers the edge of the through groove opening parallel to the first direction.

[0022] In some embodiments, the width of the through groove is greater than or equal to mm and less than or equal to 100 mm.

[0023] In some embodiments, the width of the through groove gradually increases in the direction away from the massage device.

[0024] In some embodiments, the width of the through slot remains constant in the direction away from the massage device.

[0025] In some embodiments, the car seat also includes a cover located on the side of the backrest foam opposite to the massage device and covering the through groove;

[0026] When at least part of the massage head extends out of the groove, the massage head indirectly contacts the back of the human body through the cover.

[0027] In some embodiments, the covering includes an abrasion-resistant layer and a contact layer;

[0028] The wear-resistant layer is attached to the side of the backrest foam that is away from the massage device, and the contact layer is located on the side of the wear-resistant layer that is away from the backrest foam.

[0029] In a second aspect, this application provides an automobile, characterized in that it includes an automobile seat as described in the first aspect.

[0030] In this embodiment, during the massage process of the massage device, the massage head can extend at least partially out of the through groove and come into contact with the back of the human body. That is, the massage head can massage different areas of the human back by passing through the strip-shaped through groove of the car seat back foam. Firstly, the massage head will not excessively compress the back foam, thereby avoiding damage to the back foam or loss of elasticity in its recovery. Secondly, not having to massage through the back foam also helps to enhance the massage sensation of the massage head on the human back, thereby ensuring the massage strength and effect of the massage head.

[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0059] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0060] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0061] Currently, in order to improve the user experience, car seats are usually equipped with massage functions to relieve driving fatigue.

[0062] In related technologies, the massage function of car seats usually uses air bags or mechanical massage heads. Air bag massage mainly achieves back massage by inflating and deflating air bags, while mechanical massage heads achieve back massage by moving the massage head.

[0063] In comparison, airbag massage has advantages such as simple structure, small space occupation, and the ability to reduce seat thickness and increase car interior space, but it also has disadvantages such as weak massage intensity and poor massage effect. Mechanical massage head has advantages such as strong massage intensity and good massage effect, but it also has disadvantages such as complex structure, large space occupation, and not the ability to reduce seat thickness.

[0064] Currently, mechanical massage heads are increasingly used in car seats due to their superior massage effects. However, current mechanical massage heads require a foam pad inside the seat back to massage the user's back, which not only results in poor massage effectiveness but may also lead to excessive deformation and damage to the foam pad.

[0065] Therefore, this application provides an automobile seat and an automobile, which will be described in detail below.

[0066] First, refer to Figure 1 , Figure 1 An exploded view of a car seat according to an embodiment of this application is shown, wherein the car seat includes a backrest foam 100, a massage device 200, and a seat frame 300.

[0067] Specifically, the backrest foam 100 is installed on the seat frame 300. The seat frame 300 serves as a rigid support structure for the car seat, providing rigid support for the passenger. The backrest foam 100 provides flexible support for the passenger's back, ensuring the passenger's back comfort.

[0068] The backrest foam 100 has at least one through-slot 101 extending through both sides of the backrest foam 100. For example, see [reference needed]. Figure 2 , Figure 2 A schematic diagram of a backrest foam 100 in an embodiment of this application is shown. The through groove 101 penetrates the front of the backrest foam 100 that contacts the occupant and the back that is away from the occupant, so that the massage head 210 of the massage device 200 can pass through the backrest foam 100 and extend to the front of the backrest foam 100 to indirectly contact the back of the human body.

[0069] In this embodiment, the projection shape of the groove 101 perpendicular to the surface of the backrest foam 100 is linear, so that the massage head 210 can massage different parts of the human back through the linear groove 101. For example, the groove 101 can extend in an approximately vertical direction, so that the massage head 210 can massage the human back up and down through the approximately vertical groove 101; or, for example, the groove 101 can extend in an approximately horizontal direction, so that the massage head 210 can massage the human back left and right through the approximately horizontal groove 101.

[0070] As an exemplary embodiment, see [reference] Figure 3 , Figure 3 A schematic diagram of a backrest foam 100 in an embodiment of this application is shown, wherein the linear shape can be rectangular, that is, the projection shape of the through groove 101 perpendicular to the surface of the backrest foam 100 is rectangular, and the through groove 101 is a rectangular through groove. As another exemplary embodiment, the linear shape can be... Figure 4 The linear shape shown Figure 4 In the linear shape and Figure 3 The difference is that its two ends are curved.

[0071] As yet another exemplary embodiment, Figure 5 Another schematic diagram of the backrest foam 100 in an embodiment of this application is shown, wherein, Figure 5 In the linear shape and Figure 3 The difference is that the linear shape presents a meandering, serpentine form. As yet another exemplary embodiment, Figure 6 This paper shows another structural schematic diagram of the backrest foam 100 in an embodiment of this application, wherein the linear shape can be a strip-shaped arc.

[0072] As yet another exemplary embodiment, Figure 7 Another schematic diagram of the backrest foam 100 in an embodiment of this application is shown, wherein, Figure 7 In the linear shape and Figure 3 The difference is that one end of the linear shape is spherical; as yet another exemplary embodiment, Figure 8 Another schematic diagram of the backrest foam 100 in an embodiment of this application is shown, wherein, Figure 8 In the linear shape and Figure 3 The difference is that the linear shape has spherical ends.

[0073] It is understood that, in this application, "linear shape" refers to a shape that is approximately strip-shaped. Figures 5 to 8 This is merely an exemplary embodiment of the through-slot 101 in this application. Those skilled in the art can modify the shape of the through-slot 101 under the guidance of this application, for example... Figure 7 The upper end of the linear shape is spherical, but it can actually be modified so that only the lower end of the linear shape is spherical.

[0074] For example, the material of the backrest foam 100 can be, but is not limited to, soft foam, rigid foam and semi-rigid foam, such as foamed rubber and foamed plastic.

[0075] The massage device 200 can be installed on the seat frame 300. The massage device 200 is located on the side of the backrest foam 100 away from the human body. The massage device 200 includes a drive mechanism 220 and a massage head 210. The drive mechanism 220 is used to drive the massage head 210 to move, so as to massage the back of the occupant through the massage movement of the massage head 210. For example, the massage head 210 can repeatedly contact the human back in a manner similar to tapping or pressing to achieve a pressing or tapping massage process on the human back; for another example, the massage head 210 can move left and right on the human back to achieve a kneading massage process on the human back; for yet another example, the massage head 210 can perform tapping, pressing, or kneading movements while moving along the extension direction of the through groove 101 to achieve a walking tapping, pressing, or kneading movement, thereby performing tapping, pressing, or kneading massage on different parts of the human back.

[0076] In some embodiments of this application, see Figure 9 , Figure 9 A schematic diagram of a massage device 200 according to an embodiment of this application is shown. The drive mechanism 220 includes a drive component 221 and a massage arm 222. A massage head 210 is mounted on the massage arm 222. The drive component 221 is used to drive the massage arm 222 to rotate around a first axis X. For example, the drive component 221 can drive the massage arm 222 to swing back and forth around the first axis X to realize the pressing or tapping massage process of the human back; for another example, the drive component 221 can drive the massage arm 222 to rotate around the first axis X, thereby causing the massage head 210 to rise and pass through the backrest foam 100 to contact the human back; for yet another example, the drive component 221 can drive the massage arm 222 to rotate around the first axis X, thereby causing the massage head 210 to fall down and retract to the side of the backrest foam 100 away from the human back.

[0077] See the schematic diagram of a massage device 200. Figure 10 , Figure 10 Another schematic diagram of the massage device 200 in this application embodiment is shown, wherein the drive mechanism 220 includes a movable member 2211, a fixed member 2212 and a connecting rod 2213. The first end of the connecting rod 2213 is rotatably connected to the massage arm 222, and the second end of the connecting rod 2213 is rotatably connected to the movable member 2211. The movable member 2211 can move relative to the fixed member 2212 along a preset straight line. Under the movement of the movable member 2211, the connecting rod 2213 can pull the massage arm 222 to rotate around the first axis X.

[0078] It is understood that the implementation of the drive mechanism 220 is not limited to this. Those skilled in the art can make adaptive adjustments to the drive mechanism 220 according to actual needs (such as the number of massage arms 222). For example, the drive mechanism 220 may include, but is not limited to, hydraulic telescopic rods, pneumatic telescopic rods, electric telescopic rods, ball screws, rack and pinion mechanisms, and other linear motion mechanisms; or, for example, see [reference needed]. Figure 11 , Figure 11 Another schematic diagram of the massage device 200 in the embodiment of this application is shown, wherein the massage device 200 includes two massage arms 222, and the drive assembly 220 includes two moving parts 2211, which can drive the two massage arms 222 to rotate respectively.

[0079] In the embodiments of this application, see Figure 12 , Figure 12 This illustration shows a schematic diagram of a car seat backrest massage state in an embodiment of this application. During the massage process of the massage device 200, the massage head 210 extends at least partially out of the through groove 101 and can indirectly or directly contact the back of the human body. That is, the massage head 210 can pass through the car seat backrest foam 100 through the approximately strip-shaped through groove 101 to massage different areas of the human back without having to massage through the backrest foam 100. Firstly, the massage head 210 will not excessively compress the backrest foam 100, thereby avoiding damage to the backrest foam 100 or loss of elasticity in its recovery. Secondly, not having to massage through the backrest foam 100 also helps to enhance the massage sensation of the massage head 210 on the human back, thereby ensuring the massage strength and massage effect of the massage head 210.

[0080] It is understood that the massage process of the massage device 200 referred to in the embodiments of this application may be, but is not limited to, a fixed or mobile process of moving the massage head 210 to perform massage, such as tapping, pressing or kneading.

[0081] In some embodiments of this application, such as the embodiment where the drive mechanism 220 includes a drive assembly 221 and a massage arm 222, please continue reading. Figure 12 During the rotation of the massage arm 222, the radius R corresponding to the rotation trajectory of the massage head 210 is less than or equal to the length L of the through groove 101 along the linear shape extension direction, so as to avoid the massage head 210 being obstructed by the backrest foam 100 during the rotation of the massage arm 222, which would prevent the massage head 210 from passing through the through groove 101 or damage the backrest foam 100.

[0082] It should be noted that in some possible embodiments, the radius R corresponding to the rotation trajectory of the massage head 210 can be similar to the length L of the through groove 101 along the linear shape extension direction. For example, the length L of the through groove 101 along the linear shape extension direction is 30cm, while the radius R corresponding to the rotation trajectory of the massage head 210 can be 25cm. In some possible embodiments, the magnitude of the radius R corresponding to the rotation trajectory of the massage head 210 can be much smaller than the magnitude of the length L of the through groove 101 along the linear shape extension direction. For example, the length L of the through groove 101 along the linear shape extension direction is 30cm, while the radius R corresponding to the rotation trajectory of the massage head 210 can be 5cm, that is, the length L of the through groove 101 along the linear shape extension direction is six times the radius R corresponding to the rotation trajectory of the massage head 210.

[0083] In some possible embodiments, the radius R corresponding to the rotation trajectory of the massage head 210 can be greater than the length L of the through groove 101 along its linear shape extension direction, wherein the value of the greater length ranges from 10mm to 15mm. That is to say, in practical applications, the massage head 210 makes slight contact with the inner wall of the through groove 101 during rotation, and within this range, the inner wall of the through groove 101 is subjected to relatively light pressure from the massage head 210, thus allowing for a relatively light degree of pressure.

[0084] In some embodiments of this application, such as the embodiment where the drive mechanism 220 includes a drive assembly 221 and a massage arm 222, see [reference]. Figure 13 , Figure 13 This illustration shows another state of the car seat back massage in this embodiment of the application, wherein the massage arm 222 has a first rotation position and a second rotation position; when the massage arm 222 is in the first rotation position, the massage head 210 extends at least partially out of the through groove 101 and can contact the back of the human body; when the massage arm 222 is in the second rotation position, the massage head 210 is located on the side of the backrest foam 100 away from the human body.

[0085] It should be noted that the first rotation position is the position of the massage arm 222 when the massage device 200 is performing a massage. At this time, the massage arm 222 is extended away from the drive component 221 so that the massage head 210 on the massage arm 222 can pass through the through groove 101 of the backrest foam 100 and contact the back of the human body for massage. The second rotation position is the position of the massage arm 222 when the massage device 200 stops massaging. At this time, the massage arm 222 is retracted near the drive component 221 so that the massage head 210 can be retracted to the side of the backrest foam 100 away from the human body, so as to avoid the occupant feeling a foreign object sensation when sitting.

[0086] In some embodiments of this application, see Figure 14 , Figure 14This illustration shows another state of the car seat back massage in an embodiment of this application. The massage arm 222 can also swing back and forth in a direction perpendicular to the first axis X to facilitate kneading and massaging the human back.

[0087] As an example, see Figure 15 , Figure 15 This illustration shows another state diagram of the car seat backrest massage in this embodiment. The massage arm 222 also has a first swing position and a second swing position. The massage arm 222 can swing back and forth between the first swing position and the second swing position so that the massage head 210 can move left and right on the back of the human body to realize the kneading massage process of the human back. At the same time, when the massage arm 222 is in the first swing position and the second swing position, although the massage arm 222 and / or the massage head 210 squeeze the backrest foam 100, the degree of compression on the backrest foam 100 is small, so it will not cause damage to the backrest foam 100. At the same time, the width of the through groove 101 of the foam can be set to a narrower width, for example, the width of the through groove 101 can be set to be greater than or equal to 15mm and less than or equal to 100mm, so that the backrest foam 100 as a whole can provide sufficient area of ​​flexible support for the back of the passenger, ultimately improving the static seating comfort of the passenger.

[0088] As yet another example, see [reference] Figure 16 , Figure 16 This illustration shows another state of the car seat back massage in this embodiment. The massage arm 222 also has a first swing position and a second swing position. The massage arm 222 can swing back and forth between the first swing position and the second swing position. The massage arm 222 and / or the massage head 210 can squeeze the backrest foam 100 when it is in the second swing position, but will not squeeze the backrest foam 100 when it is in the first swing position. The width of the through groove 101 of the foam can also be set to a narrower width, so that the backrest foam 100 as a whole can provide sufficient area of ​​flexible support for the back of the passenger, ultimately improving the static seating comfort of the passenger.

[0089] It is understood that the present application's description of whether the massage arm 222 and / or massage head 210 squeezes the foam backrest 100 during the swinging process is not limited to the above embodiments. For example, the massage arm 222 and / or massage head 210 may squeeze the backrest foam 100 when it is in the first swinging position, but will not squeeze the backrest foam 100 when it is in the second swinging position; or, for another example, the massage arm 222 and / or massage head 210 may not squeeze the backrest foam 100 when it is in either the first swinging position or the second swinging position.

[0090] In some embodiments of this application, such as embodiments where the massage arm 222 can also reciprocate in a direction perpendicular to the first axis X, see [reference needed]. Figure 17 as well as Figure 18 , Figure 17 Another schematic diagram of the massage device 200 in an embodiment of this application is shown. Figure 18 A schematic diagram of a connecting rod 2213 in an embodiment of this application is shown, wherein the fixing member 2212 includes a base plate 22121, a drive shaft 22122, a first motor 22123 and an eccentric rotating shaft 22124, and the connecting rod 2213 includes a bushing 22131 and a connecting rod 22132.

[0091] Specifically, the drive shaft 22122 and the first motor 22123 are mounted on the base plate 22121. The drive shaft 22122 has a lead screw portion, and the moving member 2211 is fixed with a lead screw nut, which cooperates with the lead screw portion. The drive shaft 22122 is rotatably mounted on the base plate 22121. The first motor 22123 is used to drive the drive shaft 22122 to rotate. During the rotation of the drive shaft 22122, the lead screw nut moves on the lead screw portion of the drive shaft 22122, thereby driving the lead screw nut and driving the moving member 2211 to move. Finally, the moving member 2211 moves relative to the fixed member 2212 in a preset direction, and pulls the massage arm 222 to move through the connecting rod 2213.

[0092] The massage arm 222 is rotatably mounted on the eccentric shaft 22124. The first motor 22123 is also used to drive the eccentric shaft 22124 to rotate. The connecting rod 2213 includes a bushing 22131 and a connecting rod 22132. The bushing 22131 is rotatably mounted on the moving part 2211. The first end of the connecting rod 22132 is rotatably connected to the bushing 22131, and the second end of the connecting rod 22132 is hinged to the massage arm 222. The first connecting rod 22132 can rotate relative to the bushing 22131 about the second axis Y, and the second axis Y is perpendicular to the first axis X.

[0093] It should be noted that when the first motor 22123 drives the eccentric shaft 22124 to rotate, the massage arm 222 swings back and forth in the direction perpendicular to the first axis X. At this time, the connecting rod 22132 can also rotate relative to the bushing 22131 in the direction perpendicular to the first axis X. Therefore, the connecting rod 2213 does not restrict the massage arm 222 from swinging back and forth in the direction perpendicular to the first axis X. During the process of the massage arm 222 swinging back and forth in the direction perpendicular to the first axis X, the massage head 210 massages the back of the human body by moving left and right, so as to realize the kneading massage process of the back of the human body, thereby avoiding the phenomenon that the connecting rod 2213 restricts the massage arm 222 from driving the massage head 210 to knead and massage the back of the human body.

[0094] In some embodiments of this application, such as embodiments where the massage arm 222 compresses the backrest foam 100 when the massage arm 222 is in a first swing position or a second swing position, see [reference]. Figure 19 , Figure 19 An exploded view of a backrest foam 100 in an embodiment of this application is shown, wherein the backrest foam 100 is fitted with a protective member 102, the protective member 102 being in contact with at least a portion of the inner wall surface of the through groove 101; and / or, the protective member 102 wraps around at least a portion of the edge of the opening of the through groove 101, so that the protective member 102 protects the area of ​​the backrest foam 100 near the location of the through groove 101, avoiding damage to the backrest foam 100 due to pressure caused by the swing of the massage arm 222.

[0095] As an example, see Figure 20 , Figure 20 A cross-sectional schematic diagram of the backrest foam 100 in an embodiment of this application is shown, wherein the through groove 101 extends along a first direction, and the protective member 102 is fitted to the inner wall surface of the through groove 101 parallel to the first direction, and the protective member 102 covers the edge of the opening of the through groove 101 parallel to the first direction. Taking the through groove 101 extending in an approximately vertical direction as an example, the protective member 102 can protect the inner wall surface and edge of the through groove 101 parallel to the vertical direction. Since the inner wall surface and edge of the through groove 101 parallel to the vertical direction may come into contact with the massage head 210 (for example, when the massage head 210 is in the first swing position or the second swing position), the protective member 102 can prevent the backrest foam 100 from being damaged by pressure due to the swing of the massage arm 222.

[0096] It is understood that the protective element 102 may be, but is not limited to, a plastic shell, abrasion-resistant fabric, or elastic fabric, and this application does not impose any specific limitations.

[0097] In some embodiments of this application, see further reference. Figure 20 The width of the through groove 101 gradually increases in the direction away from the massage device 200. That is to say, the opening width on the back of the backrest foam 100 is usually larger than that on the other hand, the opening width on the back of the backrest foam 100 is usually smaller. On the one hand, the larger opening on the back can facilitate the guidance of the massage head 210 through the through groove 101. On the other hand, the smaller opening on the front can increase the contact area between the front of the backrest foam 100 and the back of the human body, thereby improving the user's static sitting comfort.

[0098] It is understood that in some possible embodiments, the width of the through slot 101 may also remain unchanged in the direction away from the massage device.

[0099] It is understood that in some possible embodiments, the width of the through groove 101 may also gradually decrease in the direction away from the massage device 200.

[0100] In some embodiments of this application, see Figure 21 and Figure 22 , Figure 21Another schematic diagram of the backrest foam 100 in this embodiment is shown, wherein a cover 103 is also installed on the side of the backrest foam 100 away from the massage device 200. The cover 103 is located on the side of the backrest foam 100 away from the massage device 200 and covers the through groove 101. When the massage head 210 extends at least partially out of the through groove 101, the massage head 210 can indirectly contact the back of the human body through the cover 103. That is to say, the massage head 210 can massage the back of the human body through the cover 103, so as to protect the backrest foam 101 through the cover 103.

[0101] For example, the covering 103 may include, but is not limited to, coverings such as fabric or leather. For example, the fabric may be, but is not limited to, Oxford cloth, nylon, Kevlar fiber, carbon fiber, bulletproof nylon, polyester fabric, nylon fabric, etc.; the leather may be, but is not limited to, genuine leather, recycled leather, artificial leather or synthetic leather.

[0102] In some embodiments of this application, see Figure 23 , Figure 23 This illustration shows another schematic diagram of the backrest foam 100 in an embodiment of this application. The cover 103 includes a wear-resistant layer 1031 and a contact layer 1032. The wear-resistant layer 1031 is attached to the side of the backrest foam opposite to the massage device 200, and the contact layer 1032 is located on the side of the wear-resistant layer 1031 opposite to the backrest foam.

[0103] It should be noted that the wear-resistant layer 1031 can be, but is not limited to, a fabric that meets wear-resistant requirements, in order to avoid the phenomenon that the contact layer 1032 will continue to wear down after the massage head 210 has been worn through for a long time; the contact layer 1032 can be, but is not limited to, genuine leather, recycled leather, artificial leather or synthetic leather, etc., so that the seat surface has light resistance, scratch resistance and is easy to clean.

[0104] It is understood that the wear-resistant layer 1031 can be directly attached to the contact layer 1032, or a flexible device, such as a heating pad or a ventilation bag, can be provided between the wear-resistant layer 1031 and the contact layer 1032.

[0105] It is worth noting that the above description of the massage device 200 is intended to clearly illustrate the implementation and verification process of this application. Those skilled in the art can also make equivalent modifications or further designs under the guidance of this application. For example, the first motor 22123 can drive the eccentric shaft 22124 to rotate through a worm gear, belt or other transmission mechanism.
