Abstract

The invention discloses an automatic heat insulation bicycle cushion, which comprises a support frame and a cushion, wherein the top end of the support frame is fixedly connected with the cushion, a container is arranged on the support frame, an evaporation liquid is hermetically filled in the container, the lowest phase change temperature of the evaporation liquid is 39 ℃, the top end of the container is hermetically communicated with a pipeline, 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, the evaporating liquid absorbs heat continuously and keeps vaporizing continuously under the irradiation of sunlight, so that the gas which is expanded continuously in the container passes through the pipeline to enter the air cavity of the folding cover, and the folding cover which is shrivelled originally continuously extends and stands up under the filling of the gas, so that more than half of the cushion can be coated, and a good sun-shading effect is achieved. The bicycle seat cushion has the outstanding characteristics that the bicycle seat cushion can be coated and shaded without being driven by additional limited energy, energy is saved, the environment is protected, and green travel in summer is promoted.

Description

Automatic thermal-insulated bicycle cushion

Technical Field

The invention relates to the technical field of vehicles, in particular to an automatic heat insulation bicycle seat cushion.

Background

Along with the development of sharing economy, sharing single-vehicle explosive type appears in each street head lane of city, has made things convenient for people's green trip of short distance. But its cushion of sharing bicycle among the conventional art is general all adopts black rubber cushion, and it insolate under the sunshine can reach 70 ℃ at most, and thermal conductivity is poor, leads to the cooling to need very long one end time, if the pedestrian that drives the way directly sits and causes the low temperature scald very easily on the cushion not cooling, nevertheless to the lower sharing bicycle of cost, it can't be equipped with special sunshade parking stall, therefore under the high temperature in summer, make the utilization ratio of bicycle reduce, be not convenient for people's green trip.

Disclosure of Invention

The invention aims to solve the problems and provides an automatic heat insulation bicycle seat cushion. In order to achieve the purpose, the invention adopts the following technical scheme:

the automatic heat insulation bicycle cushion comprises a support frame and a cushion, wherein the top end of the support frame is fixedly connected with the cushion, a container is arranged on the support frame, evaporation liquid is filled in the container in a sealing mode, the lowest phase change temperature of the evaporation liquid is 39 ℃, the top end of the container is communicated with a pipeline in a sealing mode, the support frame is further fixedly connected with a fixing frame, a fixing block is arranged at the port of the fixing frame, an inflatable folding cover is fixedly connected onto the fixing block, and the folding cover can cover more than half of the size of the cushion after being inflated.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example one

Referring to fig. 1 to 4, an automatic thermal insulation bicycle cushion comprises a support frame 1 and a cushion 2, the cushion 2 is fixedly connected to the top end of the support frame 1, a container 3 is arranged on the support frame 1, an evaporation liquid is hermetically filled in the container 3, the lowest phase change temperature of the evaporation liquid is 39 ℃, a pipeline 4 is hermetically communicated with the top end of the container 3, the support frame 1 is further fixedly connected with a fixing frame 6, a fixing block 7 is arranged at the port of the fixing frame 6, an inflatable folding cover 5 is fixedly connected to the fixing block 7, and the folding cover 5 can cover more than half of the volume of the cushion 2 after being inflated.

In a preferred embodiment of the present invention, the folding cover 5 may have a U-shaped structure, and both ends thereof are fixed by a pin so as to be covered from the rear side of the seat cushion 1.

In the preferred embodiment of the present invention, the folding cover 5 is formed by sealing two parts of a folding outer cover 51 and a folding inner cover 52, and an air chamber 53 is formed between the folding outer cover 51 and the folding inner cover 52, and the air chamber 53 is communicated with the pipeline 4.

Further, the folding outer cover 51 and the folding inner cover 52 are both folded into a zigzag wave-shaped structure, and the wavelength of the folding outer cover 51 in each repetition period is greater than that of the folding inner cover 52 in each repetition period, and when the air chamber 53 is filled with air, the folding outer cover 51 and the folding inner cover 52 continuously stand upright and are continuously stretched into line segments from the zigzag waves, so that a larger sun-shading range is provided for the cushion 2, and the space on the cushion 2 is not occupied during storage.

When a bicycle is placed in the sun and is irradiated by sunlight, the cushion 2, the support frame 1 and the container 3 fixedly connected with the cushion continuously absorb heat, the container 3 absorbs heat and transfers the heat to the evaporating liquid in the container, when the temperature reaches the boiling point of the evaporating liquid, a large amount of steam is generated, the evaporating liquid continuously absorbs heat and maintains continuous vaporization of the evaporating liquid, and the gas which continuously expands in the container 3 passes through the pipeline 4 to enter the gas cavity 53 of the folding cover 5 because the molecular distance of the gas is larger, at the moment, the originally shriveled folding cover 5 continuously extends and stands up under the filling of the gas, and the pin shaft is used as the shaft center to extend, so that more than half of the cushion 2 can be coated, and a good sun shading effect is achieved.

Example two

Referring to fig. 4, in the second embodiment, the use flexibility of the folding cover is further increased on the basis of the first embodiment, and the specific connection mode is as follows:

fixed block 7 rotates to be connected in the port department of mount 6, fixedly connected with reset spring 8 on the fixed block 7, and reset spring 8 keeps away from the one end fixed connection of fixed block 7 on support frame 1.

Further, the one end fixedly connected with that mount 6 is close to fixed block 7 adopts stopper 9 of L type structure, and stopper 9's effect lies in: the fixing block 7 can only drive the folding cover 5 to rotate for a fixed angle, so that the folding cover is prevented from excessive movement and cannot be reset under the tension of the reset spring 8.

Because the fixed block 7 is connected on the fixed frame 6 in a rotating mode, the foldable cover 5 which is not contracted is pushed down from the cushion 2 when the foldable cover is used by a pedestrian, and the reset spring 8 is arranged to pull the fixed block 7 and the foldable cover 5 connected with the fixed block through the tension of the fixed block, so that the foldable cover is prevented from being shifted under the pushing of the user and cannot achieve a good sun-shading effect.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
