[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention provides a steering support, including a fixed base 10 and a bogie 20. The bogie 20 is mounted on the fixed base 10. The fixed base 10 is provided with a first moving part 31, a second moving part 32, and a third moving part 33. A first moving member 41 is provided on the first moving part 31 and moves within the first moving part 31. A second moving member 42 is provided on the second moving part 32 and moves within the second moving part 32. A third moving member 43 is provided on the third moving part 33 and moves within the third moving part 33. The bogie 20 is rotatably connected to the first moving member 41, the second moving member 42, and the third moving member 43. When the bogie 20 rotates, at least two of the first moving member 41, the second moving member 42, and the third moving member 43 move. The fixed base 10 of this invention is relatively fixed, and the bogie 20 rotates on the fixed base 10. The three moving parts move in the same plane. The bogie 20 generally rotates and adjusts in the horizontal plane. It is hinged to the three moving parts through three fixed points. Through the synchronous constraint of the three moving parts, the bogie 20 can only rotate within a limited range in the plane, realizing adjustment in a specific direction. This invention can realize the directional change of the bogie 20 within a limited range and has high support performance. Its structure is flat, thin, and compact. A seat cushion can be installed on the bogie 20 for seat cushion steering adjustment. The top of the first moving part 41, the second moving part 42, and the third moving part 43 is provided with a vertical rotating shaft 60, and the bogie 20 has corresponding shaft holes to connect with the three rotating shafts 60.
[0024] Furthermore, in the steering support provided by this utility model, the first moving part 31 and the second moving part 32 are symmetrically arranged, and the third moving part 33 is located at the center of symmetry between the first moving part 31 and the second moving part 32. The left-right symmetrical arrangement of the first moving part 31 and the second moving part 32 ensures that the left and right steering range of the bogie 20 is also symmetrical and consistent. Furthermore, in the steering support provided by this utility model, the first moving part 31 is a slide rail, the first moving component 41 is a slider, the second moving part 32 is a slide rail, the second moving component 42 is a slider, the third moving part 33 is a slide rail, and the third moving component 43 is a slider, with the slider sliding on the corresponding slide rail. The sliding of the slider on the slide rail ensures smooth and noiseless sliding. The use of slide rails and sliders in this utility model is only a preferred solution for relatively movable connection; similar alternative structures such as grooves and sliders with similar effects can also be used, which are also within the scope of this utility model. Furthermore, in the steering support provided by this utility model, the first moving part 31 and the second moving part 32 are both linear slide rails. The ends of the first moving part 31 and the second moving part 32 are positioned close to each other on one side, while the ends of the first moving part 31 and the second moving part 32 are positioned far apart on the other side. In this embodiment, the bogie 20 is a T-shaped or Y-shaped frame, and the connection points of the first moving part 41 and the second moving part 42 with the bogie 20 are symmetrically arranged on the left and right sides of the bogie 20. Further, in the steering support provided by this utility model, the third moving part 33 is a linear slide rail, and the third moving part 33 is located on the centerline between the first moving part 31 and the second moving part 32. The middle part of the bogie 20 is connected to the third moving part 43, and the three connection points of the bogie 20 and the three moving parts are not on the same straight line. The first moving part 31 and the second moving part 32 are arranged obliquely, forming an angle between them. With the side of the angle as the inside, when the bogie 20 turns left, the left end of the bogie 20 (the first moving part 31) moves inward and the right end of the bogie 20 (the second moving part 32) moves outward until the first moving part 41 moves to the inside of the first moving part 31. At this time, when the bogie 20 turns right, the left end of the bogie 20 moves outward and the right end of the bogie 20 moves inward until the second moving part 42 moves to the inside of the second moving part 32. During this unidirectional rotation, the third moving part 43 will move outward and then inward to complete one reciprocating motion.
[0025] Preferably, in the steering support provided by this utility model, a directional member 51 is provided between the bogie 20 and the fixed base 10. The directional member 51 is fixed to the bogie 20, and a positioning part 52 is provided on the fixed base 10. The directional member 51 is engaged with the positioning part 52. The engagement of the directional member 51 and the positioning part 52 can maintain the bogie 20 at a specific angle.
[0026] Furthermore, in the steering support provided by this utility model, the directional component 51 includes a positioning post 53. The positioning post 53 contains a ball bearing 55 and an elastic element 54 that drives the ball bearing 55 to protrude from the bottom of the positioning post 53. The elastic element 54 can be a spring. There are at least two positioning portions 52, each a positioning recess that engages with the ball bearing 55. In this embodiment, the bogie 20 rotates at 90°, and two positioning recesses are symmetrically arranged on the left and right sides. There is a certain gap between the positioning post 53 and the fixed seat 10. During steering, the ball bearing 55 of the positioning post 53 rolls on the fixed seat 10. When the positioning post 53 moves above the positioning recess, the ball bearing 55 is pressed into the positioning recess under the action of the elastic element 54. The user can hear a click, indicating that the steering adjustment is complete. When the ball bearing 55 wants to move out of the positioning recess, this structure provides a certain resistance, ensuring a certain holding force when steering to the preset angle.
[0027] Furthermore, in the steering support provided by this utility model, the directional component 51 further includes a limiting plate 56, which is fixedly connected to the directional component 51. The fixed base 10 is provided with limiting blocks 57 that cooperate with the limiting plate 56. In this embodiment, there are two limiting blocks 57, symmetrically arranged left and right, used to limit the left and right movement range of the bogie 20, and they abut against both ends of the limiting plate 56. Furthermore, in the steering support provided by this utility model, a limiting cover 58 is also provided at the limiting block 57, and the limiting plate 56 moves from below the limiting cover 58. The limiting plate 56 moves within the gap between the limiting cover 58 and the fixed base 10, without contacting either. Furthermore, in the steering support provided by this utility model, one end of the limiting cover 58 is provided with an guide ramp 59, which is located below the bogie 20. The guide plate 59 tilts upward to guide the movement of the limiting plate 56 into the limiting cover 58, which is located on one side of the positioning recess and is used to accommodate the upward movement of the limiting plate 56 after it enters and mates with the positioning recess.
[0028] In summary, the fixed base of this invention is relatively fixed, the bogie rotates on the fixed base, and the three moving parts move in the same plane. The bogie generally rotates and adjusts in a horizontal plane, and is hinged to the three moving parts through three fixed points. Through the synchronous constraint of the three moving parts, the bogie can only rotate within a limited range in the plane, achieving adjustment in a specific direction. This invention can realize the directional change of the bogie within a limited range, has high support performance, and its structure is flat, thin, and compact. A seat pad can be installed on the bogie for seat pad steering adjustment.
