An automatic heat-insulating bicycle seat cushion

Abstract

The invention discloses an automatic heat-insulating bicycle seat cushion, which comprises a support frame and a seat cushion. The top end of the support frame is fixedly connected with a seat cushion. A container is arranged on the support frame, and the inside of the container is sealed and filled with evaporating liquid. The minimum phase transition temperature of the evaporating liquid is 39° C., the top of the container is sealed and communicated with a pipe, the support frame is also fixedly connected with a fixing frame, and a fixing block is arranged at the port of the fixing frame. When the bicycle is placed in the sun, it is irradiated by the sun’s rays, and the evaporating liquid absorbs heat continuously and maintains its continuous vaporization, so the continuously expanding gas in the container passes through the pipe and enters the air cavity of the folding cover. The deflated folding cover continuously stretches and stands upright under the filling of gas, so that more than half of the seat cushion can be covered, so as to play a good sunshade effect. The outstanding feature of the present invention is that it can realize the covered sunshade of the bicycle seat cushion without additional limited energy drive, which is energy-saving and environmentally friendly, and promotes green travel in summer.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an automatic heat-insulating bicycle seat cushion. Background technique [0002] With the development of the sharing economy, shared bicycles have exploded in the streets and alleys of the city, making it convenient for people to travel green for short distances. However, the seat cushions of the shared bicycles in the traditional technology are generally made of black rubber cushions, which can reach up to 70 ℃ in the sun, and have poor thermal conductivity, resulting in a long time for cooling down. For pedestrians on the road, if Sitting directly on the seat cushion without cooling down can easily cause low temperature burns, but for low-cost shared bicycles, they cannot be equipped with special shaded parking spaces. Therefore, in the high temperature of summer, the utilization rate of bicycles is reduced, which is inconvenient for people. Green travel. SUMMARY OF THE INV...

Problems solved by technology

However, the seat cushions of shared bicycles in traditional technology generally use black rubber cushions, which can reach up to 70°C when exposed to sunlight, and have poor thermal conductivity, which requires a long time to cool down. For pedestrians on the road, if Sitting directly on the cushion without cooling down can easily cause low-temperature burns, but for shared bicycles with low cost, they cannot be equipped with special shaded parking spaces. Therefore, under the high temperature in summer, the utilization rate of bicycles is reduced, which is not convenient for people Green travel
