DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-4 The utility model provides a technical solution: a car seat cushion with adjustable height, including a seat cushion and a backrest 1, such as Figure 1 As shown, the seat cushion and the backrest 1 are provided with a mechanism fixed to the car seat (not shown in the figure), the seat cushion includes a seat cushion cover 2, the interior of the seat cushion cover 2 is provided with a height adjustment mechanism, the seat cushion cover 2 is sleeved on the outside of the height adjustment mechanism, the seat cushion cover 2 is made of elastic material to adapt to the adjustment of the height adjustment mechanism, the height adjustment mechanism includes a bottom plate 3 and a top plate 4, the bottom plate 3 and the top plate 4 are respectively rectangular plates, the bottom plate 3 and the top plate 4 are arranged parallel, the bottom plate 3 and the top plate 4 are respectively fixedly connected with a first connecting plate 5 at one end of the surface opposite to the top plate 4, the number of the first connecting plates 5 on the bottom plate 3 and the top plate 4 are two, and the two first connecting plates 5 are arranged At both sides of the bottom plate 3 and the top plate 4, a movable plate 6 is movably provided at one end of the bottom plate 3 corresponding to the end away from the first connecting plate 5. The movable plate 6 is a long strip plate and extends along the width direction of the bottom plate 3. A slide plate 8 corresponding to the movable plate 6 is movably provided on the surface of the top plate 4. The slide plate 8 is a long strip plate and extends in the same direction as the length direction of the movable plate 6. The lower surface of the slide plate 8 and the upper surface of the movable plate 6 are respectively fixedly connected with a second connecting plate 9. A support rod 10 is connected between the first connecting plate 5 and the second connecting plate 9. The support rod 10 is in a cross shape, and the two crossed support rods 10 are rotatably connected to each other, such as Figure 1 As shown, by controlling the movable plate 6 to slide along the length direction of the bottom plate 3, the top plate 4 can be pushed to move by the support rod 10, and the distance between the bottom plate 3 and the top plate 4 can be adjusted, thereby adjusting the height of the seat cushion;

[0019] Specifically, the end surface of the top plate 4 is penetrated with a movable groove 11, and the slide plate 8 is slidably arranged on the inner surface of the movable groove 11. Since the slide plate 8 is located inside the movable groove 11, the overall thickness of the seat cushion is reduced, which facilitates the use of the seat cushion.

[0020] Specifically, the surface of the bottom plate 3 is symmetrically provided with plates 12, and an adjusting screw 13 is rotatably provided between the plates 12. The adjusting screw 13 is extended along the length direction of the bottom plate 3, and the adjusting screw 13 is threadedly connected to the movable plate 6. One end of the adjusting screw 13 is fixedly connected with an adjusting knob 14, and the adjusting knob 14 is located on the outside of the cushion cover 2, so that when the adjusting screw 13 is driven to rotate by the adjusting knob 14, the movable plate 6 slides under the action of the thread cooperation, thereby adjusting the height of the top plate 4 through the support rod 10;

[0021] Specifically, the movable plate 6 is screwed with the adjusting screw 13 through the buffer sleeve 15, and a through groove is provided on the end surface of the movable plate 6. The buffer sleeve 15 is slidably arranged inside the through groove. Limiting rings are respectively arranged at both ends of the buffer sleeve 15 to prevent the buffer sleeve 15 from being separated from the movable plate 6, and an elastic element is arranged between the buffer sleeve 15 and the movable plate 6. The elastic element can be a spring, and the spring is sleeved on the outside of the buffer sleeve 15, and the two ends of the spring are respectively in contact with the limiting ring and the movable plate 6. The adjusting screw 13 passes through the buffer sleeve 15 and is screwed with the buffer sleeve 15, so that the buffer sleeve 15 can overcome the elastic element to slide relative to the movable plate 6, so that the top plate 4 and the bottom plate 3 can move relatively to form a buffer, thereby increasing the comfort of the equipment, so that the thickness of the cushion cover 2 can be appropriately reduced to prevent the overall thickness of the cushion from being too large;

[0022] Specifically, the outer wall of the buffer sleeve 15 is provided with a slide groove 7, and the inner wall of the through groove is provided with a slider corresponding to the slide groove 7. The slide groove 7 extends along the length direction of the buffer sleeve 15. When the buffer sleeve 15 slides in the through groove, the slider slides inside the slide groove 7 to prevent the buffer sleeve 15 from rotating relative to the movable plate 6.

[0023] When the utility model is used, the adjusting knob 14 can be rotated to drive the adjusting screw 13 to rotate, and the movable plate 6 can be controlled to slide under the action of the threaded cooperation. The support rod 10 can be used to adjust the distance between the bottom plate 3 and the top plate 4, and the height of the seat cushion can be adjusted. The buffer sleeve 15 can overcome the sliding of the elastic element relative to the movable plate 6, and the top plate 4 and the bottom plate 3 can be relatively displaced to form a buffer, thereby increasing comfort.
