It is a green and environmentally friendly means of transportation. There are many types of bicycles, including single-person bicycles, double-person bicycles, and multi-person bicycles.

[0003] At present, the heat dissipation performance of bicycle seats on the market is relatively poor, especially in the hot summer, when people ride bicycles, due to the poor heat dissipation effect of the bicycle seat cushion, people feel strongly uncomfortable when riding in the summer. Summary of the invention

[0007] A seat cushion, the seat cushion is covered on the vehicle seat frame, the seat cushion comprises a covering layer and a filling layer, the filling layer is arranged in the covering layer, a plurality of heat dissipation structures are arranged in the filling layer, and the plurality of heat dissipation structures are arranged symmetrically;

[0008] The heat dissipation structure comprises an elastic cavity, a plurality of air inlets and a plurality of air outlets, wherein the air inlets and the air outlets are both connected to the elastic cavity, and the diameter of the outlet end of the air outlet is smaller than the diameter of the end connected to the elastic cavity.

[0009] As a further description of the above technical solution:

[0010] An outer blocking layer is arranged inside the air outlet, an inner blocking layer is arranged inside the outer blocking layer, and a first through hole is arranged on the inner blocking layer.

[0011] As a further description of the above technical solution:

[0012] The structure of the air outlet is the same as that of the air inlet.

[0013] As a further description of the above technical solution:

[0014] A plurality of springs are arranged in the elastic cavity, and the plurality of springs are arranged in the elastic cavity.

[0015] As a further description of the above technical solution:

[0016] A hydrophobic layer is arranged on the coating layer, and the hydrophobic layer is a super-hydrophobic nano coating.

[0017] As a further description of the above technical solution:

[0018] The cladding layer is provided with a plurality of ventilation channels, the channel walls of the ventilation channels are provided with a plurality of second through holes, and the second through holes are connected with the air outlet or the air inlet.

[0019] As a further description of the above technical solution:

[0020] A third through hole is arranged on the seat frame at a position corresponding to the ventilation passage.

[0025] In summary, due to the adoption of the above-mentioned technical scheme, the beneficial effect of the present invention is as follows: during riding, the left leg and the right leg alternately step on the bicycle pedal. During the process of the left leg stepping on the left pedal, the left half of the buttocks will press the heat dissipation structure on the left, the right half of the buttocks will be slightly lifted, and the center of gravity of the human body will tilt toward the left half. At this time, after the elastic cavity in the heat dissipation structure on the left is squeezed, the elastic cavity can allow the air inside it to enter the interior through the air outlet. Since the diameter of the outlet end of the air outlet is smaller than the diameter of the end connected to the elastic cavity, the air can be compressed to release heat and then the temperature is lowered to become cold air for heat dissipation. After the squeezing force disappears, the elastic cavity rebounds and air is taken in through the air inlet to prepare for the next heat dissipation. Similarly, during the process of the right leg stepping on the right pedal, the right half of the buttocks will be cooled. In this way, the left and right halves of the seat cushion cool alternately, thereby improving the heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] See also Figure 1-5 The present invention provides a technical solution: a comfortable bicycle seat heat dissipation structure, comprising:

[0041] Car seat frame 1;

[0042] A seat cushion 2, the seat cushion 2 is covered on the vehicle seat frame 1, the seat cushion 2 comprises a covering layer 21 and a filling layer 22, the filling layer 22 is arranged in the covering layer 21, a plurality of heat dissipation structures 3 are arranged in the filling layer 22, and the plurality of heat dissipation structures 3 are arranged symmetrically;

[0043] The heat dissipation structure 3 includes an elastic cavity 31 , a plurality of air inlet holes 32 and a plurality of air outlet holes 33 . The air inlet holes 32 and the air outlet holes 33 are both connected to the elastic cavity 31 . The diameter of the outlet end of the air outlet hole 33 is smaller than the diameter of the end connected to the elastic cavity 31 .

[0044] An outer barrier layer 8 is arranged inside the air outlet 33, an inner barrier layer 9 is arranged inside the outer barrier layer 8, and a first through hole 10 is arranged on the inner barrier layer 9. When air is inletted, external gas enters through the air inlet and through the first through hole to complete the passage of gas, and when air is outletted, the internal gas pushes the inner barrier layer against the outer barrier layer, so that the inner barrier layer outside the first through hole is attached to the outer barrier layer to complete the blockage.

[0045] The structure of the air outlet 33 is the same as that of the air inlet 32. Both the air outlet and the air inlet are one-way vents.

[0046] A plurality of springs 4 are arranged in the elastic cavity 31, and the plurality of springs 4 are arranged in the elastic cavity 31. This facilitates the elastic cavity to be reset.

[0047] The coating layer 21 is provided with a hydrophobic layer 5, which is a super hydrophobic nano coating, which effectively prevents rainwater from gathering on the surface of the coating layer and can effectively reduce rain attenuation. The super hydrophobic nano coating is a reactive silane-containing nano coating with a particle size of 4-80nm and a contact angle with water of more than 160 degrees.

[0048] The coating layer 21 is provided with a plurality of ventilation channels 6, and the channel wall of the ventilation channels 6 is provided with a plurality of second through holes, which are connected with the air outlet 33 or the air inlet 32. This facilitates ventilation and heat dissipation.

[0049] A third through hole 7 is provided on the seat frame 1 at a position corresponding to the ventilation channel 6, so as to prevent rainwater from accumulating on the seat frame.

[0050] The filling layer 22 is made of EVA resin material.

[0051] The coating layer 21 is a resin fiber fabric layer with a microporous structure, which can further improve the heat dissipation effect.

[0052] Working principle: During riding, the left leg and the right leg step on the bicycle pedal alternately. When the left leg steps on the left pedal, the left half of the buttocks will press the heat dissipation structure on the left, and the right half of the buttocks will be slightly lifted, and the center of gravity of the human body will tilt toward the left half. At this time, after the elastic cavity in the heat dissipation structure on the left is squeezed, the elastic cavity can allow the air inside it to enter the interior through the air outlet. Since the diameter of the outlet end of the air outlet is smaller than the diameter of the end connected to the elastic cavity, the air can be compressed to release heat and then the temperature is lowered to become cold air for heat dissipation. After the squeezing force disappears, the elastic cavity rebounds and air is taken in through the air inlet to prepare for the next heat dissipation. Similarly, when the right leg steps on the right pedal, the right half of the buttocks will be cooled. In this way, the left and right halves of the seat cushion cool alternately, thereby improving the heat dissipation effect.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
