[0002] Seats are commonly seen in our daily lives. With the changes in different scenes, flexible seats with a softer elastomer layer can achieve better support for the human body and provide more comfortable seat fit and comfort when the human body sits.

[0003] According to the Chinese patent publication number: CN212630348U, an elastic seat structure includes a seat assembly, a chair back and an elastic assembly, the seat assembly includes a seat surround and a support frame, a back rod is provided on each side of the chair back, the back rod is rotatably connected to the rear end of the seat surround, the elastic assembly includes an elastic strip, the elastic strip is connected between the seat assembly and the chair back, and the elastic strip is configured to deform when the chair back rotates to provide a restoring elastic force.

[0004] In the above scheme, the elastic strip can provide the restoring elastic force after the seat back is rotated, without the need for a complicated elastic device, thus saving costs. However, it still has the following disadvantages: the seat structure cannot adjust the elastic structure according to the needs of the user, which limits the use range of the seat structure and reduces the flexibility and use effect of the seat structure. Utility Model Content

[0005] The purpose of the utility model is to provide an elastic seat structure to solve the problem that the seat structure cannot be adjusted according to the needs of the user, which leads to a limited use range of the seat structure and further reduces the flexibility and use effect of the seat structure.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: an elastic seat structure, including a base, the base is arranged below the seat cushion, two fixing holes are provided on the rear side of the inner wall of the base, a bearing is fixed to the inner wall of the fixing hole, fixing blocks are fixed on the left and right sides of the inner wall of the base, a placement hole is provided on the left side of the fixing block, a through hole is provided on the rear side of the fixing block, the through hole extends into the left placement hole, the through hole is connected with the placement hole, a threaded column is slidably inserted into the inner wall of the through hole, the threaded column is fixed to the inner wall of the bearing inner ring, a support frame is provided on the inner wall of the base, a plurality of springs are fixed to the bottom surface of the support frame, the other end of the spring is fixed to the inner bottom surface of the base, a plurality of elastic ropes are fixed on the left and right sides of the support frame, and the elastic ropes are entangled with the outer wall of the threaded column.

[0007] Preferably, two fixing rings are arranged on the rear side of the base, inner walls of the fixing rings are provided with threads, and the fixing rings are threadedly connected to the threaded columns.

[0008] Preferably, an elastic plate is fixed to the rear side of the base, a mounting plate is fixed to the top surface of the elastic plate, a plurality of arc plates are threadedly connected to the front side of the mounting plate, and an elastic net is fixed to the inner wall of the arc plate.

[0009] Preferably, a U-shaped plate is fixed to the rear side of the mounting plate, a placement plate is fixed to the front side of the U-shaped plate, a headrest is fixed to the front side of the placement plate, and a receiving groove is provided on the front side of the headrest.

[0010] Preferably, a sound insulation pad is fixed to the top surface of the base, and the top surface of the sound insulation pad is fixed to the bottom surface of the seat cushion.

[0011] Preferably, two heating plates are fixed to the inner bottom surface of the base.

[0012] Compared with the prior art, an elastic seat structure adopting the above technical solution has the following beneficial effects:

[0013] 1. Through the cooperation of the threaded column and the elastic rope, the elasticity of the support frame can be adjusted so that the seat structure can be adjusted according to the weight and needs of the user. When the staff rotates the threaded column to tighten the elastic rope, the support frame is in a horizontal state, thereby satisfying the use of lighter users; when the staff rotates the threaded column to loosen the elastic rope, the support frame will move downward under the tension of the spring, thereby satisfying the use of heavier users, thereby improving the flexibility and use effect of the seat structure. The threaded column can be limited and fixed by the fixing ring. After the staff has adjusted the tension of the elastic rope, the fixing ring can be rotated to connect with the threaded column, thereby preventing the threaded column from rotating, thereby improving the stability of the threaded column;

[0014] Second, the elastic net can support the user's back to prevent the curved board from shaking and causing damage to the user's back, so that the user can better lean on the curved board, thereby providing a more comfortable rest experience. The receiving groove allows the head to better fit the headrest, thereby providing additional support for the head and reducing the burden on the neck and shoulders. When the head is properly placed in the receiving groove, it can effectively reduce neck fatigue and discomfort and improve riding comfort;

[0015] 3. The noise generated by the spring is reduced by the sound insulation pad, thereby reducing the interference of the noise to the seat user and providing a quieter sitting environment. At the same time, the sound insulation pad can also serve as a buffer layer to protect other devices in the base from external vibration and impact, extend its life and improve reliability. The seat cushion can be heated by the heating plate, so that the heating plate can provide additional warmth to the user in cold weather, making the user feel warm and comfortable, increasing the comfort of the seat, thereby further increasing the diversified functions of the seat and providing users with more choices and enjoyment.
