[0038] The cushion 1, seat assembly 10, and vehicle according to embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] Reference Figure 1-3 As shown, the seat cushion 1 according to an embodiment of the present invention includes: a seat cushion body 11, a seat cushion frame 12 and a seat cushion flange 13. The seat cushion body 11 is mounted on the seat cushion frame 12. The seat cushion flange 13 is at least partially located on the outside of the seat cushion body 11. The seat cushion flange 13 is connected to the seat cushion frame 12 and is adjustable in height relative to the seat cushion frame 12.

[0040] Specifically, the seat cushion 1 can be used in the seat assembly 10 of a vehicle, the seat cushion frame 12 can be fixedly connected to the vehicle body, the seat cushion body 11 and the seat cushion flange 13 can both be installed above the seat cushion frame 12, the seat cushion frame 12 can support and fix the seat cushion body 11 and the seat cushion flange 13, the seat cushion flange 13 is at least partially located on the outside of the seat cushion body 11, the seat cushion flange 13 is adjustable relative to the seat cushion frame 12, and the direction of adjustment of the seat cushion flange 13 can be... Figures 1-3 The up and down directions in the middle.

[0041] It should be noted that in some embodiments, the seat cushion flange 13 may be entirely located on the outer side of the seat cushion body 11, and the seat cushion flange 13 and the seat cushion body 11 may not overlap in the vertical direction, so as to facilitate the raising, lowering, installation, disassembly, and maintenance of the seat cushion flange. In other embodiments, a portion of the seat cushion flange 13 is on the outer side of the seat cushion body 11, and another portion of the seat cushion flange 13 is on the inner side of the seat cushion body 11. The seat cushion flange 13 may be an L-shaped structure, and the seat cushion body 11 may limit the raising and lowering of the portion of the seat cushion flange 13 located on the inner side of the seat cushion body 11 to prevent the seat cushion flange 13 from coming off.

[0042] When the driver or passenger needs to sit on the seat cushion 1, the seat cushion flange 13 can be lowered to reduce the height of the seat cushion flange 13 protruding upward relative to the seat cushion body 11, thereby increasing the seat width of the seat cushion 1. At this time, the seat cushion body 11 can support the driver's and passenger's buttocks and legs, and the seat cushion flange 13 can provide certain lateral support to the driver's and passenger's buttocks and legs, thereby improving the comfort and wrapping of the seat cushion 1.

[0043] When passengers need to lie down on the seat cushion 1 to rest, the seat cushion flange 13 can be raised to increase the height of the seat cushion flange 13 protruding upward relative to the seat cushion body 11. At this time, the seat cushion body 11 can support the passenger's body, and the seat cushion flange 13 can support the passenger's head and neck, acting as a pillow, thereby improving the comfort of the seat cushion 1.

[0044] Therefore, by adjusting the height of the seat cushion flange 13, the seat cushion 1 can provide good support and comfort when sitting or lying down. When the driver or passenger is lying down to rest, there is no need to use an extra pillow. The seat cushion flange 13 can meet the needs of the driver or passenger without taking up extra space, resulting in a better user experience.

[0045] According to an embodiment of the present invention, the seat cushion 1 has a seat cushion flange 13 that is adjustable relative to the seat cushion frame 12. When the seat cushion flange 13 is lowered, it can improve the comfort and support of the seat cushion 1. When the seat cushion flange 13 is raised, it can support the head and neck of the driver or passenger lying on the seat cushion 1, thereby improving the comfort of the seat cushion 1 when lying down.

[0046] In some embodiments of the present invention, reference is made to... Figure 3As shown, the seat cushion flange 13 includes: a flange body 131 and a flange support rod 132 connected together. The seat cushion frame 12 is provided with a support sleeve 121. In the lifting direction of the seat cushion flange 13, the flange support rod 132 passes through the support sleeve 121, and the flange support rod 132 and the support sleeve 121 are guided and engaged.

[0047] Specifically, the flange body 131 may include a foam and a wrapping layer. The foam can provide comfortable support for the human body, and the wrapping layer covers the outside of the foam. The wrapping layer may be made of fabric or leather to protect the internal foam.

[0048] The flange support rod 132 is fixedly connected to the flange body 131. The seat frame 12 is provided with a support sleeve 121. Both the flange support rod 132 and the support sleeve 121 can extend along the lifting direction of the seat flange 13. The flange support rod 132 and the support sleeve 121 can be arranged coaxially. The flange support rod 132 passes through the support sleeve 121, that is, the support sleeve 121 is sleeved on the outside of the flange support rod 132. The support sleeve 121 can provide support in the radial direction of the flange support rod 132 and provide guidance in the axial direction of the flange support rod 132 to improve the stability and reliability of the lifting of the flange support rod 132.

[0049] In some embodiments of the present invention, reference is made to... Figure 3 As shown, the seat cushion 1 also includes a first locking member 14, which is installed on the seat cushion frame 12 and can be selectively locked to the flange support rod 132.

[0050] Specifically, the first locking member 14 is installed on the seat cushion frame 12. The first locking member 14 and the flange support rod 132 can be selectively locked together. When the first locking member 14 and the flange support rod 132 are released from locking, the first locking member 14 and the flange support rod 132 are separated. The flange support rod 132 can be raised and lowered along the support sleeve 121 to adjust the height of the seat cushion flange 13. After the seat cushion flange 13 is adjusted to a suitable height, the first locking member 14 and the flange support rod 132 can be locked together. At this time, the flange support rod 132 is fixed by the first locking member 14. The flange support rod 132 will maintain its relative position with the seat cushion frame 12, thereby fixing the height of the seat cushion flange 13 and providing reliable support for the driver and passengers.

[0051] In some implementations, refer to Figure 3 As shown, in the lifting direction of the seat cushion flange 13, i.e. Figure 3In the vertical direction, the flange support rod 132 has multiple spaced locking grooves 1321. The first locking member 14 includes a housing and a button, a linkage, a buckle, and a return spring mounted on the housing. The housing can be fixed to the seat frame 12. The buckle is connected to the return spring. The return spring is used to push the buckle towards the flange support rod 132 so that the buckle extends out of the housing and locks into the locking groove 1321, thereby maintaining the height of the seat flange 13. The button is connected to the buckle through the linkage. When the button is pressed, the button can drive the buckle to move away from the flange support rod 132 through the linkage and compress the return spring, so that the buckle separates from the locking groove 1321, thereby releasing the locking engagement between the buckle and the flange support rod 132, so as to adjust the height of the seat flange 13.

[0052] In some other embodiments (not shown in the figures), the first locking member 14 is configured as a locking bolt. The locking bolt passes through the support sleeve 121 in the radial direction and is threaded into the support sleeve 121. When the locking bolt is tightened, the locking bolt presses against the flange support rod 132, so that the flange support rod 132 is clamped by the locking bolt and the inner wall of the support sleeve 121, thereby realizing the locking engagement between the locking bolt and the flange support rod 132. When the locking bolt is loosened, the locking bolt separates from the flange support rod 132, thereby releasing the locking engagement between the locking bolt and the flange support rod 132.

[0053] In some embodiments of the present invention, the number of support sleeves 121 and flange struts 132 are multiple and correspond one-to-one, which helps to improve the stability of the flange body 131 and prevent the flange body 131 from tilting.

[0054] Reference Figure 3 As shown, there are two support sleeves 121 and two flange struts 132. Along the length of the flange body 131, the two support sleeves 121 and two flange struts 132 are arranged at intervals. Each flange strut 132 is inserted into its corresponding support sleeve 121, so that the flange body 131 can provide stable support for the occupants. Alternatively, the number of support sleeves 121 and flange struts 132 can also be three, four, five, etc.

[0055] According to the embodiment of the present invention, the seat cushion 1 can be raised and lowered relative to the seat cushion frame 12 by setting mechanical structures such as the flange support rod 132 and the first locking member 14. The seat cushion 1 has a simple structure, low manufacturing and maintenance costs, and is convenient and reliable to use.

[0056] In other embodiments of the present invention (not shown in the figures), the seat cushion flange 13 can also be raised or lowered relative to the seat cushion frame 12 by an electric or hydraulic drive mechanism. For example, the seat cushion flange 13 includes a flange body 131 and a telescopic rod, which is an electric telescopic rod or a hydraulic telescopic rod. The flange body 131 is connected to the seat cushion frame 12 through the telescopic rod. The driver or passenger can control the extension and retraction of the telescopic rod through the central control screen or voice commands, thereby realizing the raising and lowering of the seat cushion flange 13.

[0057] In some embodiments of the present invention, reference is made to... Figures 1-3 As shown, in the width direction of the seat cushion 1, the seat cushion flange 13 and the seat cushion body 11 are fitted together. The width direction of the seat cushion 1 can be... Figures 1-3 In the left and right direction, when the seat cushion flange 13 and the seat cushion body 11 are in contact, the seat cushion flange 13 can ensure the support and wrapping of the driver and passenger, and avoid large gaps between the seat cushion flange 13 and the seat cushion body 11, so as to prevent items from falling between the seat cushion flange 13 and the seat cushion body 11.

[0058] In some embodiments of the present invention, in the width direction of the cushion 1, i.e. Figures 1-3 In the left and right directions, seat cushions 13 can be provided on both sides of the seat body 11. When the driver or passenger is in a sitting position, the seat cushions 13 on both sides can be adjusted to a suitable height to provide better lateral support and wrapping for the driver or passenger. When the driver or passenger lies flat in the left and right direction, one side of the seat cushion 13 can be raised to support the head and neck of the driver or passenger, and the other side of the seat cushion 13 can be raised to support the waist of the driver or passenger, so as to improve the comfort of the driver or passenger. In addition, when the driver or passenger lies on their side in the left and right direction, one side of the seat cushion 13 can be raised to support the head and neck of the driver or passenger, and the other side of the seat cushion 13 can be lowered to avoid the seat cushion 13 being too high and pressing against the waist of the driver or passenger, thus improving the comfort of the driver or passenger.

[0059] Reference Figures 4-6 As shown, a seat assembly 10 according to another embodiment of the present invention includes: a seat cushion 1, a backrest 2, and an armrest 3. The seat cushion 1 is the same as the seat cushion 1 described in the above embodiment. The backrest 2 is connected to the seat cushion frame 12. The armrest 3 includes a connecting arm 31 and a supporting arm 32. The connecting arm 31 has a first connecting end 311 and a second connecting end 312. The first connecting end 311 is connected to the supporting arm 32, and the second connecting end 312 is detachably connected to the backrest 2. The armrest 3 has a first usage position and a second usage position. In the first usage position, the first connecting end 311 is located above the second connecting end 312, and the supporting arm 32 and the seat cushion 1 are both located on the same side of the backrest 2. In the second usage position, the first connecting end 311 is located below the second connecting end 312, and the supporting arm 32 and the seat cushion 1 are both located on the same side of the backrest 2.

[0060] Specifically, the backrest 2 is connected to the seat cushion frame 12, and the backrest 2 can be used to support the back of the driver and passenger. The armrest 3 is detachably connected to the backrest 2 through the second connecting end 312 of its connecting arm 31. By changing the position of the armrest 3 assembled to the backrest 2, the armrest 3 can have different functions. For example, when the connecting arm 31 is in the first use position (i.e., Figure 4 As shown in the diagram, the armrest 3 can be used to support the arm of the driver or passenger sitting on the seat cushion 1. The connecting arm 31, in the second use position (i.e.,...) Figure 5 (As shown in the image), the armrest 3 can be used to support the head and neck of the driver or passenger lying on the seat cushion 1.

[0061] The armrest 3 can be an L-shaped structure. The armrest 3 includes a connecting arm 31 and a support arm 32 connected at an angle. The connecting arm 31 has a first connecting end 311 and a second connecting end 312. The first connecting end 311 is connected to the support arm 32, and the second connecting end 312 is detachably connected to the backrest 2.

[0062] When the armrest 3 is installed on the backrest 2 in the first use position, the first connecting end 311 is located above the second connecting end 312, at least part of the support arm 32 is higher than the connecting arm 31, and both the support arm 32 and the seat cushion 1 are located on the front side of the backrest 2. Thus, the support arm 32 has a higher height, and the support arm 32 can support the arm part of the driver and passenger sitting on the seat cushion 1 to ensure the comfort of the driver and passenger.

[0063] When the driver or passenger is lying on the seat cushion 1 and needs the armrest 3 to support their head and neck, the armrest 3 can be switched from the first use position to the second use position. That is, firstly, the armrest 3 in the first use position is separated from the backrest 2 at the second connecting end 312, then the armrest 3 is flipped in a mirror image along the horizontal plane, and finally the second connecting end 312 is installed on the backrest 2. At this time, the first connecting end 311 is located below the second connecting end 312, at least part of the support arm 32 is lower than the connecting arm 31, and both the support arm 32 and the seat cushion 1 are located on the front side of the backrest 2. Thus, the support arm 32 has a low height, and the support arm 32 can support the head and neck of the driver or passenger lying on the seat cushion 1 to ensure the comfort of the driver or passenger lying down.

[0064] It should be noted that when the driver or passenger is lying on the seat cushion 1, the head and neck of the driver or passenger can be supported by the armrest 3 of the second use position, or by raising the seat cushion flange 13, or by using both the armrest 3 of the second use position and the raised seat cushion flange 13 to support the head and neck of the driver or passenger, so as to meet the usage needs of different drivers and passengers.

[0065] According to the embodiment of the present invention, the seat assembly 10 has a seat cushion flange 13 that is adjustable relative to the seat cushion frame 12, and an armrest 3 that has a first use position suitable for supporting the arm and a second use position suitable for supporting the head and neck. The seat assembly 10 can adapt to different postures of the driver and passenger, and the seat assembly 10 has strong functionality and comfort, and has good product competitiveness.

[0066] In some embodiments of the present invention, reference is made to... Figures 4-6 As shown, the support arm 32 has a first support surface 321 and a second support surface 322 facing away from each other. In the second use position, the first support surface 321 is located below the second support surface 322, and the second support surface 322 is higher than its middle position at both ends near and away from the connecting arm 31.

[0067] Specifically, in Figure 4 In the first usage position shown, the first support surface 321 is located above the second support surface 322. That is, the first support surface 321 is the upper surface of the support arm 32, and the second support surface 322 is the lower surface of the support arm 32. The first support surface 321 can support the arm of the driver or passenger.

[0068] exist Figure 5 In the second usage position shown, the first support surface 321 is located below the second support surface 322. That is, the first support surface 321 is the lower surface of the support arm 32, and the second support surface 322 is the upper surface of the support arm 32. The second support surface 322 can support the head and neck of the driver and passenger. At the same time, the second support surface 322 is higher than its middle position at both ends near and far from the connecting arm 31. In other words, the front and rear ends of the second support surface 322 are higher, and the middle is lower, so that the second support surface 322 can better fit and support the head and neck of the driver and passenger, improving the comfort of the driver and passenger.

[0069] As shown in reference body 6, the first support surface 321 is a plane to facilitate the manufacturing of the support arm 32, and the second support surface 322 is an arched surface to increase the contact area between the second support surface 322 and the head and neck area of ​​the driver and passengers, thereby enhancing comfort.

[0070] In some embodiments of the present invention, the second support surface 322 is covered with a flexible material, which may be a material with low hardness such as leather or sponge, to further improve the comfort of the second support surface 322 in supporting the head and neck.

[0071] In some embodiments of the present invention, reference is made to... Figures 4-6 As shown, the backrest 2 is provided with a spline shaft 21, and the second connecting end 312 is provided with a spline hub 313. The spline shaft 21 and the spline hub 313 are detachably connected by insertion.

[0072] Specifically, the axial direction of the splined shaft 21 can be the width direction of the seat assembly 10, that is... Figures 3-6 In the left and right direction, the splined hub 313 can be inserted into the splined shaft 21 along the axial direction. Due to the meshing of the splined shaft 21 and the splined hub 313, the angle of the handrail 3 can be fixed, preventing the handrail 3 from rotating when the support arm 32 is under load, thus ensuring the load-bearing capacity of the support arm 32. At the same time, the splined hub 313 and the splined shaft 21 are easy to install and remove, so as to facilitate the disassembly and assembly of the handrail 3 and the switching between the first and second use positions.

[0073] In some embodiments of the present invention, the seat assembly 10 further includes a second locking member, which is mounted on the backrest 2 and selectively locks into the connecting arm 31.

[0074] Specifically, when the second locking member is released from the locking engagement with the connecting arm 31, the second locking member separates from the connecting arm 31, and the connecting arm 31 can be removed from the backrest 2 to facilitate the flipping of the armrest 3, allowing the armrest 3 to switch between the first and second use positions. After the armrest 3 is switched to the use position and assembled onto the backrest 2, the second locking member can be locked into the connecting arm 31. At this time, the connecting arm 31 is fixed by the second locking member, and the armrest 3 will maintain the switched use position, preventing the armrest 3 from separating from the backrest 2.

[0075] In some embodiments, the second locking element is constructed as a locking pin, which is detachably mounted on the spline shaft 21 on the backrest 2. When the locking pin is inserted into the spline shaft 21, the locking pin can axially lock and limit the connecting arm 31 at the free end of the spline shaft 21 to prevent the armrest 3 from coming off the spline shaft 21. When the locking pin is pulled out of the spline shaft 21, the locking pin can release the axial locking and limiting of the connecting arm 31 to facilitate the disassembly and assembly of the armrest 3.

[0076] In some embodiments of the present invention, reference is made to... Figure 4 and Figure 5 As shown, the armrest 3 is located on the side of the seat cushion flange 13 away from the seat cushion body 11.

[0077] Specifically, when the armrest 3 is located on the side of the seat cushion flange 13 away from the seat cushion body 11, both the armrest 3 and the seat cushion flange 13 are located on the same side of the seat assembly 10. When the driver or passenger lies on the seat cushion 1, one side of the seat cushion flange 13 can be raised, and the armrest 3 on the same side can be switched to the second use position. This allows the seat cushion flange 13 and the armrest 3 on the same side of the seat assembly 10 to jointly support the head and neck of the driver or passenger, thereby increasing the support area of ​​the seat assembly 10 for the head and neck and increasing the comfort of the head and neck of the driver or passenger.
