[0040] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
[0041] like Figures 1-6 As shown, a seat cushion with adjustable wings 2 according to this embodiment mainly comprises: a seat cushion body 1, adjustable wings 2, and a drive member 3. The seat cushion body 1 mainly comprises a seat cushion frame 11 and seat cushion foam 10, and the adjustable wings 2 mainly comprise support wires 21, a connecting structure, and wing foam 20. When the seat cushion with adjustable wings 2 is used in a car seat, the adjustable wings 2 can be installed on one side of the seat cushion or on both sides of the seat cushion, and the user can configure the adjustable wings 2 according to actual needs.
[0042] The seat cushion body 1 has a support surface 100 for passengers to sit on. Specifically, the seat cushion body 1 includes a seat cushion frame 11 and a seat cushion foam 10 arranged on the seat cushion frame 11. The seat cushion frame 11 serves as a strength support for the seat cushion body 1, and the seat cushion foam 10 serves as a comfort component to ensure the riding comfort of the passengers. A connecting shaft 12 is provided on the seat cushion foam 10. The connecting shaft 12 can be placed in a foaming mold and foamed into one piece with the seat cushion foam 10. A plurality of bending portions 121 are formed on the connecting shaft 12. The bending portions 121 can increase the contact area with the seat cushion foam 10 and play a limiting role, thereby preventing the adjustable side wings 2 from pulling the connecting shaft 12 out of the seat cushion foam 10 during the inward and outward rotation process. It can be understood that the connecting shaft 12 of this embodiment is a connecting steel wire, which is bent multiple times to form multiple axial connection parts and multiple bending parts 121, wherein the multiple axial connection parts include a first axial connection part 120A, a second axial connection part 120B and a third axial connection part 120C arranged in sequence, and the number of axial connection parts is set according to the number of connections required by the connection structure, and each axial connection part serves as the rotation center of the corresponding connection structure.
[0043] The adjustable wings 2 are movably connected to the seat cushion body 1 and can rotate inward and outward relative to the seat cushion body 1. Specifically, the adjustable wings 2 of this embodiment primarily comprise a support wire 21 and a wing foam 20, which is disposed on and fixedly connected to the support wire 21. Specifically, the adjustable wings 2 are provided with multiple connecting structures along the length of the support wire 21, each of which is rotatably connected to the seat cushion body 1.
[0044] Specifically, the multiple connection structures of this embodiment include at least one ball-joint linkage 22C, wherein the ball-joint linkage 22C comprises a connecting ball 221, a telescopic link 222, and a link seat 223. The connecting ball 221 is rotatably mounted on the adjustable wing 2, the link seat 223 is rotatably mounted on the shaft connection, and the telescopic link 222 is telescopically mounted on the link seat 223. The telescopic link 222 has a ball sleeve 222A mounted on the ball and forming a spherical pair with the ball. In the ball-joint linkage 22C, the telescopic link 222 can telescope relative to the link seat 223, and the ball sleeve 222A on the telescopic link 222 can rotate 360 degrees relative to the connecting ball 221, thereby preventing motion interference during the inward and outward rotation of the adjustable wing 2 and relieving torque.
[0045] More specifically, the connection structure of this embodiment further includes a first connection bracket 22A and a second connection bracket 22B. The first connection bracket 22A is disposed at one end of the support wire 21, the ball-joint linkage 22C is disposed at the other end of the support wire 21, and the second connection bracket 22B is located in the middle of the wing. The multiple pivoting portions include a first pivoting portion 120A, a second pivoting portion 120B, and a third pivoting portion 120C, which are disposed in sequence. The first connection bracket 22A is rotatably disposed on the first pivoting portion 120A, the second connection bracket 22B is rotatably disposed on the second pivoting portion 120B, and the connecting rod seat 223 is rotatably disposed on the third pivoting portion 120C. Among them, the first axial connection part 120A, the second axial connection part 120B and the third axial connection part 120C are respectively provided with notches 122 for installing the first connecting bracket 22A, the second connecting bracket 22B and the connecting rod seat 223. During the actual assembly process, the first connecting bracket 22A, the second connecting bracket 22B and the connecting rod seat 223 are respectively aligned with the notches 122 on the first axial connection part 120A, the second axial connection part 120B and the third axial connection part 120C, and assembled to the connecting shaft 12, and then moved a certain distance along the axial direction, so that the connecting shaft 12 limits the first connecting bracket 22A, the second connecting bracket 22B and the connecting rod shaft to ensure that the three will not detach from the connecting shaft 12.
[0046] In this embodiment, the adjustable wing 2 has at least two connecting structures with different rotation centers. For example, the rotation centers of the first connecting bracket 22A and the second connecting bracket 22B can be set to be concentric, while the rotation center of the ball head connecting rod mechanism 22C is different from that of the first connecting bracket 22A and the second connecting bracket 22B. 360-degree rotation can be achieved through the spherical pair, and telescopic movement can be achieved through the telescopic connecting rod 222 and the connecting rod seat 223. This ensures that even if the rotation centers are different, there will be no motion interference, thereby ensuring that the adjustable wing 2 can rotate inward and outward smoothly without jamming.
[0047] The driving member 3 is disposed on the seat cushion body 1 and connected to the adjustable wing 2. The driving member 3 can drive the adjustable wing 2 to rotate inward or outward relative to the seat cushion body 1. When the driving member 3 drives the adjustable wing 2 to rotate outward relative to the seat cushion body 1, the adjustable wing 2 can be flush with the support surface 100, or the height of the adjustable wing 2 can be lower than the height of the support surface 100.
[0048] It is understood that if the only concern is to resolve the issue of passengers' legs rubbing against each other when getting off the vehicle, either rotating the adjustable wing 2 to be flush with the support surface 100 or rotating the adjustable wing 2 to a height lower than the support surface 100 can achieve this goal. Optimally, if, in addition to resolving the issue of passengers' legs rubbing against each other when getting off the vehicle, it is also necessary to ensure passenger comfort when taking a nap, then the adjustable wing 2 can be rotated outward to be flush with the support surface 100, that is, the adjustable wing 2 is flush with the center of the seat cushion.
[0049] The second connecting bracket 22B has a guide shaft 224, on which a sleeve 225 is slidably mounted. The sleeve 225 can also rotate relative to the guide shaft 224. The driving member 3 is configured as a screw motor, and the screw of the screw motor is rotatably connected to the sleeve 225.
[0050] During actual use, the adjustable wing 2 of this embodiment can be arranged on the side of the seat body so as to rotate inward and outward. The driving member 3 can drive the adjustable wing 2 to rotate, and the adjustable wing 2 can be rotated outward to be flush with the support surface 100 of the seat body 1, or the height of the adjustable wing 2 can be made lower than the height of the support surface 100, which can effectively solve the problem of passengers' legs getting off the car. The overall structure of the adjustable wing 2 is simple, and the outward and inward movements are fast and smooth. For wings with different structural shapes, by setting multiple rotation centers and providing a ball head connecting rod mechanism 22C, interference can be effectively avoided during the inward and outward flipping of the adjustable wing 2, and the application range is wide.
