Referring to fig. 1, a flowchart of steps of a method for intelligently and precisely adjusting the massage support intensity of a seat according to the present embodiment is shown.
As shown in fig. 1, the method for intelligently and accurately adjusting the massage supporting strength of the seat disclosed in the embodiment comprises the following steps:
s10, the control module acquires the pressure of the main gas path in real time through a pressure sensor arranged in the main gas path.
In the step, a pressure sensor is arranged in the main gas path, and the pressure sensor is used for collecting the pressure of the main gas path in real time and feeding back the pressure to the control module.
In this embodiment, the control module may adopt a control chip, which is in communication connection with the pressure sensor, and obtains the pressure of the main gas path in real time through the pressure sensor, so as to realize real-time monitoring of the pressure of the main gas path.
S11, controlling the working state of a pressure regulating valve connected with the main gas path according to the pressure of the main gas path, thereby controlling the pressure of the main gas path.
In this step, the control mechanism described in step S10 is connected to the pressure regulating valve, and controls the operating state of the pressure regulating valve according to the obtained main gas path pressure, thereby controlling the main gas path pressure.
Specifically, the working states of the pressure regulating valve comprise a pre-pressing state and a gas release state, when the pressure regulating valve is in the pre-pressing state, the pre-pressing force of the sealing block arranged at the gas release port of the pressure regulating valve is larger than the pressure of the main gas path, so that the main gas path is sealed, when the pressure regulating valve is in the pressure release state, the pre-pressing force of the sealing block arranged at the gas release port of the pressure regulating valve is smaller than the pressure of the main gas path, so that the gas release of the main gas path is realized, and the pre-pressing force of the sealing block arranged at the gas release port of the pressure regulating valve is regulated through the transmission mechanism.
Therefore, the control of the operation state of the pressure regulating valve in this step specifically includes: the control module controls the transmission mechanism of the pressure regulating valve to generate displacement so as to change the pre-pressure of the sealing block arranged at the gas leakage port of the pressure regulating valve, so that the pressure regulating valve is switched between a pre-pressure state and a gas leakage state.
S12, controlling the supporting strength of the seat supporting massage module connected with the main air channel by adjusting the pressure of the main air channel.
In this step, the seat support massage module is connected to the main air passage, so that the strength of the seat support massage module is adjusted when the pressure of the main air passage is adjusted.
Therefore, this embodiment acquires main gas circuit pressure in real time through the pressure sensor that sets up in main gas circuit, according to the operating condition of main gas circuit pressure control air-vent valve, change the precompression of the sealing block that the air-vent mouth department of air-vent valve set up, make it realize sealedly or the pressure release to main gas circuit, with the regulation main gas circuit pressure, realize the accurate accuse to main gas circuit pressure, thereby reach the purpose that carries out accurate regulation to the support intensity of seat support massage module, promote the comfort level of seat, bring more comfortable riding experience for the passenger.
Referring to fig. 2, a flowchart of a main air path pressure control step in a method for intelligently and precisely adjusting a massage support intensity of a seat according to the present embodiment is shown.
As shown in fig. 2, the control of the main air path pressure in the method for intelligently and accurately adjusting the massage support intensity of the seat disclosed in the embodiment includes the following steps:
s20, judging whether the pressure of the main gas path is within a preset pressure range, and if so, keeping the pressure regulating valve in a pre-pressing state.
In the implementation process, it can be understood that the main air channel pressure has a certain relation with the strength of the seat support massage module, for example, the main air channel pressure is the pressure required by the strength of the seat support massage module, and then the strength of the seat support massage module can be adjusted by adjusting the main air channel pressure.
The intensity of the seat support massage module can be controlled within a certain preset pressure range according to the comfort, and when the intensity exceeds the preset pressure range, the main air path pressure needs to be regulated, so that the step can be understood as follows; whether the main gas path pressure detected by the pressure sensor is within a preset pressure range is judged, if so, the pressure regulating valve is kept in a pre-pressing state, namely the current state is kept, and the main gas path pressure is not regulated.
S21, if not, judging whether the pressure of the main gas path is higher than a preset pressure range, if so, controlling the pressure regulating valve to be in a pressure relief state so as to regulate the pressure of the main gas path to fall into the preset pressure range, otherwise, controlling the pressure regulating valve to be in a pre-pressing state, and performing air charging operation on the main gas path through an air pump connected with the main gas path so as to regulate the pressure of the main gas path to rise into the preset pressure range.
Based on step S20, when the main air path pressure is not within the preset pressure range, the main air path pressure needs to be adjusted and controlled within the preset pressure range, so that the strength of the seat support massage module can be ensured. While the treatment schemes of the too high or too low main gas path pressure are different, and the treatment needs to be aimed at.
Therefore, the technical scheme is as follows: judging whether the pressure of the main gas path is higher than a preset pressure range, and when the pressure of the main gas path is higher than the preset pressure range, reducing the pressure of the main gas path, and controlling the pressure regulating valve to process a pressure relief state; when the pressure of the main gas path is lower than the preset pressure range, the main gas path is required to be boosted, then the pressure regulating valve is required to be controlled to be in a pre-pressing state, and the main gas path is required to be inflated at the same time.
In this embodiment, it should be noted that, in the application of the present technical solution to the use process of the seat, the air pump is always in the working state, that is, the inflated state, and then, when the strength of the seat supporting massage module needs to be within the preset pressure range, the air pump is always in the inflated state, so that the pressure regulating valve is always in the deflated state, and the working state is only changed under special conditions. When the intensity of the seat support massage module is adjusted according to the needs of a seat occupant, the pressure required by the intensity of the corresponding seat support massage module is also required to be adjusted, the corresponding preset pressure range is also changed, at the moment, when the preset pressure range is enlarged, the pressure regulating valve is required to be controlled to be in a pre-pressing state until the pressure of the main air channel is within the current preset pressure range, and then the pressure regulating valve changes the working state in real time according to the main air channel pressure detected in real time; similarly, when the preset pressure range is reduced, the pressure regulating valve needs to be controlled to be in a venting state until the main gas path pressure reaches the current preset pressure range, and then the pressure regulating valve changes the working state in real time according to the main gas path pressure detected in real time, so that the real-time monitoring and control of the main gas path pressure is realized, and the accurate control of the strength of the seat support massage module is further realized.
