[0027] As Figures 1 to 13 shown, an adjustment mechanism for assisting in riding on a vehicle seat includes a rotation mechanism 1, a rotating shaft 2, a front drive assembly 3, a link 4, and a seat frame assembly 5;

[0028] One end of the rotating mechanism 1 is provided with a front driving assembly 3, and a seat frame assembly 5 is arranged above the front driving assembly 3. One end of the front driving assembly 3 is connected to one end of a connecting rod 4, and the other end of the connecting rod 4 is connected to one end of the seat frame assembly 5. The other end of the seat frame assembly 5 and the other end of the rotating mechanism 1 are rotatably connected through a rotating shaft 2; a seat cushion sponge 6 is arranged on the top end of the seat frame assembly 5. The rotating mechanism 1 in this application is prior art, so it will not be described in detail here. The front driving assembly 3, the seat frame assembly 5 and the connecting rod 4 in this application can all rotate synchronously with the rotating mechanism 1 under the drive of the rotating mechanism 1, and finally realize the rotation of the seat cushion sponge 6, so as to facilitate adapting to the rotation needs of passengers for the car seat.

[0029] When the adjustment mechanism for assisting in riding of the car seat of the present utility model is needed for normal riding by passengers, at this time, the front driving assembly 3 is in a horizontal state, the seat frame assembly 5 and the seat cushion sponge 6 arranged on the top end of the seat frame assembly 5 are both in a horizontal state, and passengers can ride normally; when it is necessary to assist passengers in riding and standing up from the seat, the front driving assembly 3 is started, then the front driving assembly 3 drives the connecting rod 4, and the connecting rod 4 drives one end of the seat frame assembly 5 connected to the connecting rod 4 to move downward. One end of the seat frame assembly 5 is rotatably connected to the rotating mechanism 1 through the rotating shaft 2. Then, during the process of one end of the seat frame assembly 5 moving downward, one end of the seat frame assembly 5 connected to the rotating mechanism 1 rotates along the rotating shaft 2. Finally, it is realized that one end of the seat frame assembly 5 connected to the connecting rod 4 is lower, while one end of the seat frame assembly 5 connected to the rotating mechanism 1 is higher, and the whole seat is in an inclined state with one end high and one end low. In this application, one end of the seat frame assembly 5 connected to the connecting rod 4 can be arranged at the outer edge of the seat, and one end of the seat frame assembly 5 connected to the rotating mechanism 1 can be arranged near the backrest assembly. Then, it is realized that one end of the seat frame assembly 5 near the backrest is set higher, while one end of the seat frame assembly 5 connected to the connecting rod 4 is lower, which is convenient for passengers, especially the elderly and shorter people, to sit on the seat cushion sponge 6. Moreover, the inclined state with one end of the seat frame assembly 5 near the backrest being higher and the other end of the seat frame assembly 5 being lower is also convenient for the passengers' feet to contact the bottom of the vehicle, which is convenient for the passengers to slide from the seat cushion sponge 6 to the outer edge of the car seat, convenient for the passengers to stand up from the car seat, and convenient for the passengers to ride on the car seat, improving the comfort when riding on the seat and when standing up from the seat, and realizing the functions of facilitating the elderly and shorter people to sit and getting off the vehicle conveniently. Similarly, the front driving assembly 3 can also be driven to make the connecting rod 4 drive one end of the seat frame assembly 5 connected to the connecting rod 4 to move upward, so as to realize that one end of the seat frame assembly 5 connected to the connecting rod 4 is higher, while one end of the seat frame assembly 5 near the backrest assembly is lower, and the car seat is inclined from the outer edge to the backrest assembly direction from high to low, so as to meet the different needs of customers and improve the adaptability of the car seat.

[0030] As a preferred embodiment, the front drive assembly 3 in the present application includes a bottom support plate 301, a disc 302, a drive rod 303, a synchronizing shaft 304, and a motor 305;

[0031] The bottom support plate 301 is fixedly arranged on the rotating mechanism 1, and discs 302 are fixedly connected to both sides of the bottom support plate 301 respectively. One ends of drive rods 303 are fixedly connected to the two discs 302 respectively, and the other ends of the drive rods 303 are rotatably connected to the connecting rod 4; the motor 305 is arranged on the synchronizing shaft 304, and both ends of the synchronizing shaft 304 are arranged on the two discs 302 respectively.

[0032] When it is necessary to adjust the seat frame assembly 5 to be higher at the end close to the backrest assembly and lower at the end close to the outer edge to facilitate a passenger to sit on or get off the seat, first start the motor 305 to rotate forward. Then the motor 305 drives the synchronizing shaft 304 to rotate forward. Since both ends of the synchronizing shaft 304 are connected to the discs 302 respectively, the synchronizing shaft 304 drives the discs 302 to rotate. Also, since one end of the drive rod 303 is arranged on the disc 302 and the other end of the drive rod 303 is rotatably connected to the connecting rod 4, when the synchronizing shaft 304 drives the disc 302 to rotate, one end of the drive rod 303 also rotates along the synchronizing shaft 304 synchronously. At this time, one end of the drive rod 303 drives the connecting rod 4 to move downward, thereby driving one end of the seat frame assembly 5 connected to the connecting rod 4 to move downward, and the end of the seat frame assembly close to the backrest assembly rotates along the rotating shaft. Finally, it is realized that one end of the seat frame assembly 5 connected to the connecting rod 4 is low and the end of the seat frame assembly close to the backrest assembly is high, achieving the angle adjustment of the seat frame assembly 5, facilitating the angle adjustment of the seat, facilitating a passenger to stand up from the vehicle seat, facilitating a passenger to sit on the vehicle seat, and improving the comfort when sitting on the seat and when standing up from the seat. Similarly, when it is necessary to adjust the seat frame assembly 5 to be lower at the end close to the backrest assembly and higher at the end close to the outer edge to meet the needs of customers, first start the motor 305 to rotate in reverse. Then the motor 305 drives the synchronizing shaft 304 to rotate in the reverse direction. Since both ends of the synchronizing shaft 304 are connected to the discs 302 respectively, the synchronizing shaft 304 drives the discs 302 to rotate. Also, since one end of the drive rod 303 is arranged on the disc 302 and the other end of the drive rod 303 is rotatably connected to the connecting rod 4, when the synchronizing shaft 304 drives the disc 302 to rotate, one end of the drive rod 303 also rotates along the synchronizing shaft 304 synchronously. At this time, one end of the drive rod 303 drives the connecting rod 4 to move upward, thereby driving one end of the seat frame assembly 5 connected to the connecting rod 4 to move upward, and the end of the seat frame assembly close to the backrest assembly rotates along the rotating shaft 2. Finally, it is realized that one end of the seat frame assembly 5 connected to the connecting rod 4 is high and the end of the seat frame assembly 5 close to the backrest assembly is low, achieving the angle adjustment of the seat frame assembly 5 and improving the adaptability of the vehicle seat.
