DETAILED DESCRIPTION

[0018] The following is combined with Figures 1 to 3 This application is described in further detail.

[0019] The present application discloses a micro air suspension vibration reduction mechanism for a car seat. Figure 1 , 2 , including a mounting base 1 and a liftable seat support 2, a lifting component and a driving airbag 3 are arranged between the mounting base 1 and the seat support 2, the driving airbag 3 is located in the lifting component, and can drive the lifting component to drive the seat support 2 to rise and fall.

[0020] Reference Figure 3 The lifting assembly includes outer hinged arms 5 hinged to the left and right sides of the rear side of the mounting base 1, and inner hinged arms 4 hinged to the left and right sides of the rear side of the cushion support 2, the inner hinged arms 4 and the outer hinged arms 5 on the same side are hinged at their middle positions, and a mutually intersecting scissor-type hinged structure is formed between the inner hinged arms 4 and the outer hinged arms 5. In order to ensure the structural stability of the lifting assembly, a reinforcing cross bar can be set between the inner hinged arms 4 on the left and right sides. Of course, a reinforcing cross bar can also be set between the outer hinged arms 5 on the left and right sides.

[0021] The scissor-type hinge structure is formed. During operation, there will be a relatively fixed point and a relatively movable point. A displacement track for the lifting component when lifting can be set between the lifting component and the mounting base 1 and the cushion support 2. After the displacement track is designed, the inner hinge arm 4 and the outer hinge arm 5 will also be designed with corresponding adaptation structures. For example, an upper track pulley 6 is provided at the front end of the inner hinge arm 4. The upper track pulley 6 is adapted to the sliding of the displacement track on the front side of the mounting base 1. At this time, the displacement track on the front side of the mounting base 1 includes a U-shaped track opening 11 arranged inwardly. Track 7, a limiting baffle 8 is provided at the rear end of the U-shaped track 7, that is, one of the track side walls of the U-shaped track 7 is fixed to the mounting base 1, and its front end can be a sealed structure or an open structure, which can be set specifically according to actual needs; at the same time, a lower track pulley 9 can also be provided at the front end of the outer hinged arm 5, and the lower track pulley 9 is slidably adapted to the displacement track on the front side of the seat cushion support 2, and the displacement track on the front side of the seat cushion support 2 includes a concave track slide groove 10 arranged on the front side of the seat cushion support 2, and the inner side wall of the concave track slide groove 10 is provided with a track opening 11.

[0022] In order to enable the driving airbag 3 to better achieve the driving effect and the rationality of the spatial layout, the driving airbag 3 is installed in the middle position of the mounting base 1, and the driving airbag 3 is located between the outer hinged arms 5 on the left and right sides. At the same time, a driving bracket 12 is installed on the top of the driving airbag 3, and the left and right sides of the driving bracket 12 are downwardly provided with bending plates 13, and the lower ends of the bending plates 13 are bent outward to provide driving abutment plates 14, and the driving abutment plates 14 are welded to the area between the middle hinge position and the rear hinge position of the outer hinged arm 5. When the driving airbag 3 is inflated, the driving abutment plate 14 drives the outer hinged arm 5 to lift, thereby enabling the entire lifting assembly to achieve lifting, and the structure also has a certain buffering effect.

[0023] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
