Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] A bus seat based on EPP environmentally friendly material includes a base 1 and a backrest 2 fixedly disposed on one side of the top of the base 1. The backrest 2 has a plurality of first ventilation holes 3 evenly distributed on the side wall near the base 1 for back ventilation. The top of the base 1 has a plurality of second ventilation holes 4 evenly distributed on the top side for hip ventilation. A first ventilation component 5 and a second ventilation component 6 are respectively disposed on the bottom sides of the base 1. The back of the backrest 2 has a mounting groove 7. A first hollow plate 8 is detachably disposed inside the mounting groove 7. The surface of the first hollow plate 8 has a plurality of first air holes evenly distributed and connected to the first ventilation holes 3. The base 1 has a mounting cavity 9 inside. A second hollow plate 10 is detachably disposed inside the mounting cavity 9. The top of the second hollow plate 10 has a second air hole evenly distributed and connected to the second ventilation holes 4.

[0022] In this embodiment, both the base 1 and the backrest 2 are made of a metal frame, EPP environmentally friendly material, and decorative fabric.

[0023] In this embodiment, the No. 1 ventilation assembly 5 and the No. 2 ventilation assembly 6 have the same structure. The No. 1 ventilation assembly 5 includes a cylinder 51 connected to the vehicle body by bolts. A cover plate 52 is detachably provided on the top of the cylinder 51, and a piston plate 53 is slidably and sealed inside the cylinder 51.

[0024] In this embodiment, a plurality of support columns 54 are uniformly fixedly arranged on the top of the piston plate 53. The plurality of support columns 54 slide through the cover plate 52 and are jointly fixedly arranged on a pressure plate 55. A spring 56 is slidably sleeved on the outer wall of the support column 54 and located between the pressure plate 55 and the cover plate 52.

[0025] In this embodiment, an air inlet pipe 57 communicating with the interior is uniformly fixedly arranged on one side wall of the cylinder 51. Each air inlet pipe 57 is equipped with a first one-way valve that only allows gas to enter the base 1. An exhaust pipe 58 communicating with the interior is uniformly fixedly arranged on the other side wall of the air inlet pipe 57. A second one-way valve that only allows gas to be discharged is fixedly arranged inside the exhaust pipe 58. The output ends of multiple exhaust pipes 58 are connected to the same air supply pipe. The output ends of the air supply pipe are connected to the first hollow plate 8 and the second hollow plate 10 through two branch pipes respectively.

[0026] Working principle: When in use, the passenger sits on the surface of the base 1. During the vehicle's movement, the passenger's weight on the surface of the base 1 changes due to the bumps in the ground. When the surface of the base 1 is under greater pressure, the pressure plate 55 pushes the piston plate 53 downward along the inner wall of the cylinder 51. The air inside the cylinder 51 is squeezed by the piston plate 53 and output through multiple exhaust pipes 58. The gas is collected in the air supply pipe and then transported to the first hollow plate 8 and the second hollow plate 10 through two branch pipes. The air entering the first hollow plate 8 and the second hollow plate 10 is output through the first air hole and the second air hole, respectively. The air is blown towards the back and buttocks of the human body through the first vent hole 3 and the second vent hole 4, respectively, accelerating the surrounding air flow speed. When the weight at the top of the base 1 decreases, the elasticity of the support column 54 pushes the piston plate 53 upward, and the external air is drawn into the cylinder 51 through the air intake pipe 57, completing the air replenishment operation.
