Description

Technical Field

[0001] The utility model relates to a chimeric height-increasing seat cushion, belonging to the technical field of height-increasing seat cushions. Background Art

[0002] Car seat cushions are the main consumer product for car owners. It is particularly important to choose a set of comfortable and practical car seat cushions according to the season. Nowadays, there are car seat cushions made of different materials such as genuine leather, microfiber leather, artificial leather, nylon, chemical fiber, artificial wool, polyester wool, etc. on the market.

[0003] When the driver is not tall enough, a booster seat cushion is often used. The height of the embedded booster seat cushion used in the prior art is often fixed when in use, while the adjustable height of the car seat is limited. When the car seat is adjusted to the highest position, the height of the booster seat cushion will also be limited to a certain height. Since the height of the booster seat cushion cannot be adjusted after it is installed, it is difficult to find the most suitable sitting height during use of the seat cushion, which makes the booster seat cushion less practical.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] A chimeric height-enhancing seat cushion comprises a seat cushion 1, a bottom pad 2 is provided below the seat cushion 1, a pad plate 3 is provided inside the bottom pad 2, a plurality of pad blocks 4 are provided above the pad plate 3, a rotating sleeve 5 is provided above the pad block 4, a screw 6 is connected inside the rotating sleeve 5, the top of the screw 6 is fixedly connected to a pad block 7, the top of the pad block 7 is fixedly connected to a top plate 8, fixing straps 9 are provided on both sides below the bottom pad 2, and an adjustment buckle 10 is provided on the fixing strap 9, and a back cushion 11 is connected to one end of the seat cushion 1.

[0024] Specifically, a telescopic belt 12 is connected between the seat cushion 1 and the base cushion 2, and the telescopic belt 12 is arranged around the bottom of the seat cushion 1. A telescopic cavity 13 is provided on one side of the telescopic belt 12 between the seat cushion 1 and the base cushion 2. The cushion block 1 4, the rotating sleeve 5, the screw 6 and the cushion block 2 7 are respectively provided in five groups and are respectively arranged at the center of the pad 3 and the four corners of the pad pad 3. The telescopic belt 12 can follow the seat cushion 1 to expand and contract when the seat cushion 1 moves up and down. The rotating sleeve 5 and the screw 6 can be supported at different positions between the pad 3 and the top plate 8, so that the force on the top plate 8 is more even.

[0025] Specifically, a linkage gear 14 is provided on the outside of the rotating sleeve 5, and the linkage gear 14 on the rotating sleeve 5 located at the center of the pad 3 is meshed with a transmission gear 15. The bottom of the transmission gear 15 is connected to the output end of a small motor 16, and one side of each linkage gear 14 is connected to a transmission belt 17. The transmission belt 17 has tooth grooves matching the transmission gear 15 on both the inner and outer sides. A battery 18 is provided above the pad 3, and the output end of the battery 18 and the input end of the small motor 16 are electrically connected through a wire. The rotating sleeve 5 is embedded in the pad 4 and rotatably connected inside the pad 4. The transmission gear 15 can drive the linkage gear 14 to rotate, and the transmission belt 17 can simultaneously drive each linkage gear 14 and the rotating sleeve 5 to rotate, so that each screw 6 can be synchronously raised and lowered to adjust the height of the top plate 8 and the seat cushion 1.

[0026] Example 2: Please refer to Figure 1 The difference between this embodiment and embodiment 1 is that: the back cushion 11 is provided with a fixing strap 2 19, and the fixing strap 2 19 is provided with the same adjustment buckle 10 as that on the fixing strap 1 9. The fixing strap 2 19 can connect the back cushion 11 to the backrest of the car seat, thereby improving the stability of the back cushion 11 on the car seat.

[0027] The working principle of the utility model is as follows: when in use, first connect the fixing strap 1 9 to the car seat and fix the position of the seat cushion 1 and the bottom cushion 2 after adjusting the adjustment buckle 10, then connect the fixing strap 2 19 to the car seat backrest. After the height adjustment of the car seat is completed, when it is necessary to continue to adjust the heightened seat cushion, the small motor 16 can be started, and the small motor 16 drives the transmission gear 15 to rotate. When the transmission gear 15 rotates, the rotating sleeve 5 and the linkage gear 14 at the center of the pad 3 can be driven to rotate. When the rotating sleeve 5 and the linkage gear 14 at the center of the pad 3 rotate, the other rotating sleeves 5 and the linkage gear 14 can be driven to rotate through the transmission belt 17, so that each screw 6 can move upward at the same time to push the top plate 8 and the seat cushion 1 to move upward, so that the seat cushion 1 moves to a suitable height.
