Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a seat cushion front lifting structure in zero-gravity mode, including a seat frame 100, a front lifting assembly 200, and a seat base 300. The front end of the seat frame 100 is mounted on the seat base 300 via the front lifting assembly 200, and the rear end of the seat frame 100 is pivotally connected to the seat base 300. The front lifting assembly 200 includes a drive motor 210, a drive toothed plate 220, and a lifting swing arm 230. One end of the drive toothed plate 220 is sleeved on the lower horizontal tube 310 of the seat base 300, and the other end is connected to the seat frame 100 via the lifting swing arm 230. The drive motor 210 is mounted on the seat base 300 and is connected to the toothed plate 220 in a transmission manner. The drive motor 210 is located in front of the lower horizontal tube 310, and the drive toothed plate 220 is located between the drive motor 210 and the lower horizontal tube 310.

[0041] Specifically, when the user adjusts the car seat to zero-gravity mode, the drive motor 210 located at the front end of the seat base 300 drives the drive gear plate 220 to swing. The swing of the drive gear plate 220 can drive the lifting arm to swing, thereby driving the front end of the seat frame 100 to swing upward and lift. The rear end of the seat frame 100 can rotate relative to the seat base 300, thus fulfilling the requirements of the zero-gravity seat mode for the seat frame 100. In this process, the drive motor 210 is located at the front end of the seat base 300, and the drive gear plate 220 is located between the drive motor 210 and the lower cross tube 310. This arrangement avoids the drive motor 210 and the drive gear plate 220 occupying the space in the middle of the lower part of the seat frame 100, making it easier to arrange other equipment in the middle of the lower part of the seat frame 100.

[0042] In addition, by placing the drive motor 210 and the drive toothed plate 220 in front of the lower cross tube 310, the size of the drive toothed plate 220 can be increased, thereby increasing the distance between the drive toothed plate 220 and the lower cross tube 310. This increases the torque of the drive motor 210 in driving the swing arm 230 to swing and lift, thereby reducing the power of the drive motor 210, saving costs, and better enabling the drive motor 210 to self-lock, thus preventing the drive toothed plate 220 from reversing. This makes it easier to keep the seat in zero-gravity mode without the need for a high-power drive motor 210.

[0043] It should be noted that the drive tooth plate 220 and the lower horizontal tube 310 can be fixedly connected, and a bearing is set between the lower horizontal tube 310 and the seat base 300, so that a single drive motor 210 can complete the lifting of the seat frame 100.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional embodiment, the front end of the seat frame 100 has a front cross tube 110, and the end of the lifting swing arm 230 away from the drive tooth plate 220 is sleeved on the front cross tube 110.

[0045] Specifically, the lifting arm 230 is fixedly sleeved on the front cross tube 110, and a bearing is provided between the front cross tube 110 and the seat frame 100.

[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional embodiment, the rear end of the seat frame 100 has a rear cross tube 120, and the rear end of the seat base 300 is provided with a connecting seat for connecting to the rear cross tube 120.

[0047] Specifically, a bearing is provided between the rear cross tube 120 and the seat frame 100, and the rear cross tube 120 can be installed on the connecting seat, thereby ensuring that the rear end of the seat frame 100 and the seat base 300 can rotate relative to each other.

[0048] It should be noted that the rear cross tube 120 at the end of the seat frame 100 is directly mounted on the seat base 300. This arrangement improves the stability and structural strength of the car seat, thereby ensuring that the structural strength of the car seat meets the requirements for installing a three-point seat belt.

[0049] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in an optional embodiment, the outer side of the seat base 300 has a mounting base 320 for mounting the drive motor 210, and the drive motor 210 is mounted on the mounting base 320 by bolts.

[0050] Specifically, the drive motor 210 is located on the outside of the seat base 300, further reducing the space occupied under the seat frame 100.

[0051] The output end of the drive motor 210 is provided with a drive gear 211 for meshing with the drive gear plate 220. The operation of the drive motor 210 can drive the drive gear 211 to rotate, thereby causing the drive gear plate 220 to swing. A reduction gearbox is provided at the output end of the drive motor 210.

[0052] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in the optional embodiment, the drive tooth plate 220 includes a drive plate 221, a tooth plate 222, and a connecting rod 223 for pivotally connecting with the lifting swing arm 230; the drive plate 221 has a connecting hole 225 for being sleeved on the lower horizontal tube 310, and the tooth plate 222 is located between the connecting hole 225 and the connecting rod 223.

[0053] Among them, the drive gear plate 220 is in the shape of a figure 9.

[0054] Specifically, the drive plate 221, the toothed plate 222, and the connecting rod 223 are an integral structure. The drive plate 221 has a connecting hole 225 for connecting the lower horizontal tube 310. The drive plate 221 is fixedly connected to the lower horizontal tube 310. The toothed plate 222 and the connecting hole 225 are located on both sides of the drive plate 221, and the toothed plate 222 can be connected to the drive gear 211 of the drive motor 210.

[0055] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in the optional solution of this embodiment, a limiting arc groove 224 is provided on the drive plate 221, and a limiting stop bar 330 is provided on the seat base 300. The limiting stop bar 330 is located in the limiting arc groove 224; the limiting arc groove 224 is located between the toothed plate 222 and the connecting hole 225.

[0056] Specifically, a limiting arc groove 224 is provided on the drive plate 221, and a limiting stop bar 330 is fixedly provided on the seat base 300. The limiting stop bar 330 is located in the limiting arc groove 224. When the drive motor 210 drives the toothed plate 220 to rotate, it can synchronously drive the drive plate 221 to rotate. The cooperation between the limiting arc groove 224 and the limiting stop bar 330 can limit the maximum angle of the up and down swing of the drive plate 221, and prevent the toothed plate 222 from disengaging from the drive motor 210.

[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional embodiment, a protective cover plate 340 is provided on the inner side of the seat base 300 to cover the drive gear 211 of the drive motor 210; one end of the protective cover plate 340 is fixedly mounted on the seat base 300, and the other end is fixedly mounted on the limit stop bar 330.

[0058] Specifically, a protective cover 340 is provided on the inner side of the seat base 300. The protective cover 340 can cover the drive gear 211 of the drive motor 210, preventing the drive gear 211 from being affected by external factors and ensuring the normal operation of the car seat.

[0059] This embodiment provides a car seat, including a seat cushion forward lifting structure in zero-gravity mode.

[0060] Specifically, the car seat provided in this embodiment has the advantages of the aforementioned zero-gravity mode seat cushion forward lifting structure compared with the prior art, which will not be elaborated here.

[0061] 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.
