[0040] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this embodiment provides a seat cushion flip-up structure, including a seat cushion frame 100, a seat base 200, and a flip-up assembly 300; a rotary drive frame 110 is fixedly arranged on both sides of the rear end of the seat cushion frame 100, and the rotary drive frame 110 is pivotally connected to the seat base 200; the fixed end of the flip-up assembly 300 is arranged at the rear end of the seat base 200, and the driving end of the flip-up assembly 300 is pivotally connected to the rotary drive frame 110, so that the flip-up assembly 300 drives the rotary drive frame 110 to rotate the seat cushion frame 100.

[0042] Specifically, rotating drive frames 110 are provided on both sides of the rear end of the seat cushion frame 100. The rotating drive frames 110 on both sides are pivotally connected to the rear end of the seat base 200. When the seat cushion frame 100 needs to be flipped up, the flipping component 300 works to drive the rotating drive frame 110 to swing. The swinging of the rotating drive frame 110 can drive the seat cushion frame 100 to flip up, thereby exposing the storage box on the seat base 200 for users to store items. Moreover, the flipping component 300 is located at the rear end of the seat base 200. After the seat cushion frame 100 is flipped up, the flipping component 300 will not be exposed and will not occupy or affect the space under the seat cushion frame 100. In addition, the flipping components 300 are provided on both sides of the seat cushion frame 100 to improve the stability of the seat cushion frame 100 after it is flipped up.

[0043] The seat cushion frame 100 has seat cushion flipping reinforcement frames 101 on both sides, and the rotation drive frame 110 is fixedly mounted on the seat cushion flipping reinforcement frames 101.

[0044] See Figure 1 - Figure 8As shown, in the optional embodiment, the flip-up assembly 300 includes a motor mounting base 310, a drive motor 320, and a drive screw 330; the motor mounting base 310 is fixedly mounted on the seat base 200, the drive motor 320 is mounted inside the motor mounting base 310, the drive screw 330 is mounted on the drive motor 320, and one end of the drive screw 330 is pivotally connected to the rotary drive frame 110.

[0045] The rotary drive frame 110 is provided with a first pivot seat 111 for pivotally connecting with the drive screw 330.

[0046] The motor mounting base 310 has a motor mounting hole 311, the drive motor 320 is provided with a lead screw drive seat 321, the lead screw drive seat 321 is inserted into the motor mounting hole 311, and the drive lead screw 330 is inserted into the lead screw drive seat 321.

[0047] The motor mounting base 310 has an arc-shaped groove 312, and the drive screw 330 is located in the arc-shaped groove 312, so that when the drive motor 320 drives the drive screw 330, the drive screw 330 can swing with the movement of the rotary drive frame 110.

[0048] Specifically, the operation of the drive motor 320 can drive the drive screw 330 to move relative to the drive motor 320. The movement of the drive screw 330 can drive the rotary drive frame 110 to swing up or down. When the rotary drive frame 110 swings up or down, the seat cushion frame 100 can rotate relative to the seat base 200. During this process, the swing of the drive screw can drive the screw drive seat 321 to rotate within the motor mounting hole 311 of the motor mounting seat 310.

[0049] The rotary drive frame 110 is provided with a second pivot seat 112 for pivotal connection with the seat base 200. The first pivot seat 111 is located below the second pivot seat 112. The second pivot seat 112 on the rotary drive frame 110 is pivotally connected to the seat base 200. The drive screw 330 drives the rotary drive frame 110 to rotate relative to the second pivot seat 112 through the first pivot seat 111.

[0050] See Figure 1 - Figure 8 As shown, in an optional embodiment, the motor mounting base 310 is mounted on the inner wall of the seat base 200, and the drive motor 320 is mounted on the outer wall of the seat base 200.

[0051] Specifically, the motor mounting bracket 310 is installed on the inner wall of the seat base 200, and the drive motor 320 is installed on the outer wall of the seat base 200. This arrangement reduces the space occupied by the drive motor 320 under the seat cushion frame 100.

[0052] See Figure 1 - Figure 8 As shown, in the optional embodiment, the seat base 200 is provided with an assembly and maintenance window 210, which corresponds to the rotary drive frame 110.

[0053] Specifically, an assembly and maintenance window 210 is provided on the seat base 200, through which staff can easily connect the drive screw 330 and the first pivot seat 111 on the rotary drive frame 110.

[0054] This embodiment provides a car seat, including a seat cushion flip-up structure.

[0055] Specifically, the car seat provided in this embodiment has the advantages of the above-mentioned seat cushion flip-up structure compared with the prior art, which will not be elaborated here.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
