[0020] like Figures 1-5As shown, a sliding structure of a seat includes a seat cushion 1 and a fixed guide block 2. The seat cushion 1 is slidably arranged relative to the fixed guide block 2. A guide sliding structure 3 is arranged between the fixed guide block 2 and the seat cushion 1. A tension spring 4 for sliding and resetting the seat cushion 1 is connected between the seat cushion 1 and the fixed guide block 2. A gear block 5 is arranged on the seat cushion, and a gear structure 6 is arranged between the gear block 5 and the fixed guide block 2. The guide sliding structure 3 includes a slide groove 31 arranged on the seat cushion 1 and a gear structure 6 arranged on the fixed guide block 2. The slider 32 is located in the slide groove 31; the gear structure 6 includes a gear groove 61 arranged on the fixed guide block 2 and a limit block 62 arranged on the gear block 5, the limit block 62 is arranged corresponding to the gear groove 61, and the limit block 62 can be clamped in the gear groove 61; the gear block 5 is hingedly installed on the seat cushion 1, and the gear block 5 includes a toggle portion 51, a matching portion 52 and a hinge portion 53 located between the toggle portion 51 and the matching portion 52, and a hinge shaft 53 is arranged on the hinge portion 53 1, the limit block 62 is arranged on the matching portion 52, and a compression spring 54 for the gear block 5 to rotate and reset is arranged between the matching portion 52 and the seat cushion 1, and the toggle portion 51 is pushed upward to make the limit block 62 disengage from the gear slot 61 and compress the compression spring 54; the seat cushion 1 is provided with a first hook portion 111, and the fixed guide block 2 is provided with a second hook portion 21, and the two ends of the tension spring 4 are respectively connected to the first hook portion 111 and the second hook portion 21; the fixed guide block 2 includes a main body portion 2 mounted on the seat cushion 1 2 and a fixing portion 23 fixedly connected to the main body portion 22, the fixing portion 23 is located below the seat cushion 1, a plurality of mounting blocks 24 are formed below the main body portion 22, the slider 32 is located between the mounting block 24 and the fixing portion 23, a first guide groove 11 adapted to the mounting block 24 is provided on the seat cushion 1, the mounting block 24 is placed in the first guide groove 11, a second guide groove 12 adapted to the fixing portion 23 is provided below the seat cushion 1, and the fixing portion 23 is placed in the second guide groove 12.

[0021] By adopting the above technical solution, in actual use scenarios, a cushion cover will be installed on the cushion 1, and the main body 22 will be fixedly installed on the seat frame through the fixing part 23, so that the fixing guide block 2 is fixed. During the specific installation, the mounting block 24 of the main body 22 is installed in the first guide groove 11, and the slider 32 is placed in the slide groove 31, and then the fixing part 23 is installed in the second guide groove 12 below the bottom of the cushion 1, and the fixing part 23 and the slider 32 are snap-fitted and connected, and there is a snap-fit installation structure between the top surface of the fixing part 23 and the bottom surface of the slider 32. Among them, the setting of the first guide groove 11 and the second guide groove 12 can be used to accommodate and guide the sliding mounting block 24 and the fixing part 23, respectively, so that the slider 32 has better stability when sliding relative to the slide groove 31. Furthermore, the fixed guide block 2 may be provided with four mounting blocks 24 , and correspondingly, four sliders 32 , slide grooves 31 and fixing portions 23 are also provided. The four mounting blocks 24 are arranged in a rectangular shape, thus further ensuring the stability of the slider 32 sliding relative to the slide groove 31 .

[0022] Furthermore, in the present invention, since the fixed guide block 2 is fixedly mounted on the seat frame, during the sliding adjustment, the seat cushion 1 will slide closer to or away from the seat back through the guide sliding structure 3, and the setting of the gear structure 6 can make the limit block 62 engage in the gear slot 61 to achieve the limit position of the seat cushion 1 after sliding. When the sliding adjustment is required, the limit block 62 can be disengaged from the gear slot 61 by toggling the toggle portion 51 upward, so that the seat cushion 1 can slide relative to the fixed guide block 2. At this time, due to the upward toggle portion 51, the matching portion 52 will move downward and compress the compression spring 54, and the compression spring 54 provides a force to cause the gear block 5 to rotate and reset. Among them, two limit blocks 62 can be provided, so as to ensure the connection stability when the limit block 62 and the gear slot 61 are engaged.

[0023] Among them, the setting of the tension spring 4 can provide a sliding restoring force for the seat cushion 1. Specifically, after the seat cushion 1 slides forward several gears, if the toggle part 51 is continuously pushed upward, due to the force of the tension spring 4, the seat cushion 1 will directly move backward and reset to the innermost gear position, thereby making the sliding operation adjustment of the seat cushion 1 more convenient.
