Description

Technical Field

[0001] The present invention relates to the field of automotive seat detection, and specifically to a flexible full-automatic detection system applied to automotive seat ventilation and massage. Background Art

[0002] With the progress of seat comfort system technology, seats with air exchange functions have become a new type of product that is gradually accepted by people. Automotive seat ventilation refers to installing small fans in the seat cushion and backrest, sucking the air flow in the cockpit, guiding it through pipes to the upper layer of the seat, and then flowing out through the breathable holes on the seat surface to form a ventilation effect. This design can effectively improve the air circulation environment in the contact part between the human body and the seat, prevent sweating on the buttocks and back, and provide a comfortable riding experience. The seat ventilation function is mainly divided into two types: blowing type and sucking type.

[0003] Currently, in the seat industry, the detection of seat ventilation and massage depends entirely on the human senses to evaluate the ventilation and massage functions, which cannot be quantified and has a high risk of quality detection. Therefore, it is necessary to use equipment to quantify the ventilation and massage data, establish standards, achieve automated detection, and improve the quality standards.

[0004] In view of the above technical problems, this application proposes a solution. Summary of the Invention

[0005] In the present invention, by applying different ventilation parameter controls to the automotive seat and collecting the surface ventilation effect of the automotive seat, quantitative analysis of the automotive seat ventilation effect can be performed based on the collected data, and standardized verification of the automotive seat ventilation effect can be achieved according to the results of the quantitative analysis, ensuring that the detection result of the automotive seat ventilation effect will not deviate due to the subjective behavior of manual detection by personnel, and solving the problem that the automotive seat ventilation and massage functions lack a complete system for quantitative evaluation and automated detection, resulting in the inability to accurately control the quality of automotive ventilation seats. Therefore, a flexible full-automatic detection system applied to automotive seat ventilation and massage is proposed.

[0006] The object of the present invention can be achieved through the following technical solutions:

[0007] A flexible full-automatic detection system applied to automotive seat ventilation and massage, including a ventilation detection module, which is used to detect the ventilation ability of the automotive seat and obtain the ventilation coupling and ventilation hysteresis of the automotive seat;

[0008] A massage detection module, which is used to detect the massage function of the automotive seat and judge the massage frequency and massage pressure of the automotive seat;

[0009] A result input unit, which obtains the ventilation detection result through a ventilation detection module, obtains the massage detection result through a massage detection module, and generates a seat qualified signal or a seat unqualified signal according to the ventilation detection result and the massage detection result;

[0010] A cycle control unit, which controls the re-inspection process according to the seat unqualified signal;

[0011] A production line control unit, which performs corresponding production line control according to the seat qualified signal or the seat unqualified signal.

[0012] As a preferred embodiment of the present invention, the ventilation detection module further includes an air volume control module, an air volume detection module, and an analysis and generation module;

[0013] The air volume control module controls the air outlet component under the seat to blow air according to different air outlet parameters. The air outlet parameters include air volume and air speed. The air volume control module generates an image of the change of the air outlet parameters with time according to the change time and the air outlet parameters;

[0014] The air volume detection module detects the ventilation parameters above the seat, and the air volume detection module obtains an image of the change of the ventilation parameters with time according to the detected ventilation parameters and time.

[0015] As a preferred embodiment of the present invention, in the image of the change of the air outlet parameters with time, the analysis and generation module selects the points where the air volume changes, and records the time corresponding to the points where the air volume changes as the air volume input points, selects the points where the air speed changes, and records the corresponding time as the air speed input points. The analysis and generation module counts the number of the air volume input points and the air speed input points to obtain the total number of input adjustments;

[0016] In the image of the change of the ventilation parameters with time, the analysis and generation module records the time corresponding to the points where the air volume changes as the air volume output points, and records the time corresponding to the points where the air speed changes as the air speed output points. The analysis and generation module records the sum of the number of the air volume output points and the air speed output points as the ventilation change points.

[0017] As a preferred embodiment of the present invention, the method for the analysis and generation module to judge the change of the ventilation parameters is as follows:

[0018] In the image of the change of the ventilation parameters with time, calculate the change speed of the ventilation parameters to obtain the air volume change speed and the air speed change speed, and compare the air volume change speed and the air speed change speed with the corresponding thresholds respectively. Record the air volume change speed greater than or equal to the threshold and the air speed change speed greater than or equal to the threshold as the change of the ventilation parameters.

[0019] As a preferred embodiment of the present invention, the analysis and generation module compares the ventilation change points with the total number of input regulations. If the number of ventilation change points is the same as the total number of input regulations, a change coupling signal is generated; otherwise, a change difference signal is generated and sent to the result input unit, and the result input unit generates a ventilation detection unqualified signal.

[0020] After generating the change coupling signal, the analysis and generation module numbers all the air volume input points in chronological order, and at the same time numbers all the air velocity input points, air volume output points, and air velocity output points in chronological order. The analysis and generation module calculates the time difference between each group of air volume input points and air volume output points with the same number to obtain multiple groups of air volume time lag values, and calculates the time difference between each group of air velocity input points and air velocity output points with the same number to obtain multiple groups of air velocity time lag values.

[0021] The analysis and generation unit respectively performs arithmetic averaging on the air volume time lag values and the air velocity time lag values to obtain the air volume time lag mean value and the air velocity time lag mean value. The analysis and generation unit compares the air volume time lag mean value and the air velocity time lag mean value with the corresponding standard upper limits respectively to generate an air volume response abnormal signal, an air volume response normal signal, an air velocity response abnormal signal, or an air velocity response normal signal.

[0022] When the result input unit simultaneously obtains the air velocity response normal signal and the air volume response normal signal, it generates a ventilation detection qualified signal. When obtaining any one group of the air velocity response abnormal signal and the air volume response abnormal signal, it generates a ventilation detection unqualified signal.

[0023] As a preferred embodiment of the present invention, the massage detection module further includes a monitoring and capturing module and a point analysis module.

[0024] The massage detection module can enable the massage component to switch between multiple different massage control logics. The monitoring and capturing module can detect the seat surface and obtain the massage pressure and massage frequency transmitted by the massage component.

[0025] As a preferred embodiment of the present invention, the point analysis module compares the massage pressure and massage frequency with the set massage pressure and massage frequency to generate a pressure adjustment normal signal, a pressure adjustment abnormal signal, a frequency adjustment normal signal, or a frequency adjustment abnormal signal.

[0026] After the result input unit simultaneously obtains the pressure adjustment normal signal and the frequency adjustment normal signal, it generates a massage detection qualified signal. When obtaining any one group of the frequency adjustment abnormal signal and the pressure adjustment abnormal signal, it generates a massage detection unqualified signal.

[0027] As a preferred embodiment of the present invention, when the result input unit generates a massage detection failure signal or a ventilation detection failure signal, it sends a re-inspection instruction to the circulation control unit and marks the currently detected vehicle seat. The circulation control unit sends detection instructions to the ventilation detection module and the massage detection module again, so that the ventilation detection module and the massage detection module detect the marked vehicle seat again;

[0028] When the result input unit obtains a massage detection failure signal or a ventilation detection failure signal from the marked vehicle seat again, it records the vehicle seat as a failed seat.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. By applying different ventilation parameter controls to the vehicle seat and collecting the surface ventilation effect of the vehicle seat, the present invention can quantitatively analyze the ventilation effect of the vehicle seat based on the collected data, and realize the standardized audit of the ventilation effect of the vehicle seat according to the results of the quantitative analysis, ensuring that when detecting the ventilation effect of the vehicle seat, the detection results will not deviate due to the subjective behavior of manual detection by personnel, guaranteeing the consistency of the seat factory quality. At the same time, when detecting the ventilation effect of the vehicle seat, it is divided into ventilation effectiveness detection and adjustment effectiveness detection, making the detection coverage more comprehensive.

[0031] 2. In the present invention, through multiple detections of the strength and frequency of the vehicle massage function, the standardized analysis of the massage function and adjustment effect of the vehicle seat is realized, ensuring the comprehensiveness of the vehicle massage function detection, and thus effectively discovering defective vehicle seats and guaranteeing the factory quality of the vehicle seats.

[0032] 3. In the present invention, through automated detection equipment, automatic loading and unloading and automatic detection of vehicle seats are realized, and the re-inspection, marking and detection reminder of the seats can be automatically realized according to the detection results, increasing the automation degree of the detection process. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] For the convenience of those skilled in the art to understand, the present invention will be further described below with reference to the accompanying drawings.

[0034] Figure 1 is the system block diagram of the present invention;

[0035] Figure 2 is the system flow chart of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention. Embodiment

[0037] Please refer to Figure 1 - Figure 2 As shown in the figure, a flexible full-automatic detection system applied to automotive seat ventilation and massage includes a ventilation detection module, a massage detection module, a circulation control unit, a result input unit, and a production line control unit. The production line control unit is used to control the double-speed chain line body in the seat detection production line, control the operation of the double-speed chain line body by generating a loading instruction or an unloading instruction, unload the detected seat from the detection station, and move the seat to be detected to the position of the detection station.

[0038] The ventilation detection module includes an air volume control module, an air volume detection module, and an analysis and generation module.

[0039] The air volume control module is used to control the air outlet component under the seat to operate, so that the component outputs air according to different air outlet parameters. The air outlet parameters include air volume and air speed. The air volume control module changes the air volume and air speed multiple times during the detection process, records the corresponding air outlet parameters at each moment, and generates an image of the change of air outlet parameters with time according to time and air outlet parameters.

[0040] The air volume detection module detects the ventilation parameters above the seat. The ventilation parameters also include air volume and air speed. When detecting the ventilation parameters, the air volume detection module synchronously records the time, and draws a coordinate system with time as the horizontal axis and air speed and air volume as the vertical axes respectively to obtain an image of the change of ventilation parameters with time.

[0041] In the image of the change of air outlet parameters with time, the analysis and generation module selects the points where the air volume changes, and records the time corresponding to the points where the air volume changes as the air volume input points. It selects the points where the air speed changes, and records the time corresponding to the points where the air speed changes as the air speed input points.

[0042] The analysis and generation module counts the number of air volume input points and air speed input points to obtain the total number of input adjustments.

[0043] In the image of the change of ventilation parameters with time, the analysis and generation module obtains the points where the air volume changes, and records the corresponding time as the air volume output points. It records the points where the air speed changes, and records the corresponding time as the air speed output points. The analysis and generation module records the sum of the number of air volume output points and air speed output points as the ventilation change points.

[0044] When the analysis and generation module obtains the points where the ventilation parameters change, the judgment method adopted is as follows:

[0045] In the image where the ventilation parameters change with time, calculate the change speed of the ventilation parameters to obtain the air volume change speed and the wind speed change speed. Compare the air volume change speed with the corresponding threshold, ignore the air volume change speed less than the threshold, record the air volume change speed greater than or equal to the threshold as the ventilation parameter change, compare the wind speed change speed with the corresponding threshold, ignore the air volume change speed less than the threshold, and record the air volume change speed greater than or equal to the threshold as the ventilation parameter change;

[0046] The analysis and generation module compares the ventilation change points with the total number of input regulations. If the number of ventilation change points is the same as the number of the total number of input regulations, a change coupling signal is generated. If the number of ventilation change points is different from the number of the total number of input regulations, a change difference signal is generated, and the change difference signal is sent to the result entry unit through the network. After obtaining the change difference signal, the result entry unit generates a ventilation detection unqualified signal;

[0047] After generating the change coupling signal, the analysis and generation module numbers all the air volume input points in chronological order. At the same time, numbers all the wind speed input points, air volume output points and wind speed output points in chronological order. The analysis and generation module calculates the time difference between each group of air volume input points and air volume output points with the same number to obtain multiple groups of air volume time lag values. Similarly, calculates the time difference between each group of wind speed input points and wind speed output points with the same number to obtain multiple groups of wind speed time lag values;

[0048] The analysis and generation unit performs arithmetic averaging on the air volume time lag values to obtain the air volume time lag mean value, performs arithmetic averaging on the wind speed time lag values to obtain the wind speed time lag mean value. The analysis and generation unit compares the air volume time lag mean value and the wind speed time lag mean value with the corresponding standard upper limits respectively. If the air volume time lag mean value exceeds the corresponding standard upper limit, a air volume response abnormal signal is generated. If the air volume time lag mean value does not exceed the corresponding standard upper limit, a air volume response normal signal is generated. If the wind speed time lag mean value exceeds the corresponding standard upper limit, a wind speed response abnormal signal is generated. If the wind speed time lag mean value does not exceed the corresponding standard upper limit, a wind speed response normal signal is generated;

[0049] When the analysis and generation unit sends the normal wind speed response signal, normal air volume response signal, abnormal wind speed response signal, and abnormal air volume response signal to the result input unit, when the result input unit simultaneously obtains the normal wind speed response signal and normal air volume response signal, it generates a qualified ventilation detection signal, and when obtaining any one group of the abnormal wind speed response signal and abnormal air volume response signal, it generates an unqualified ventilation detection signal. Embodiment

[0050] Please refer to Figure 1 - Figure 2 As shown in the figure, the massage detection module includes a monitoring and capturing module and a point analysis module. The massage detection module can control the massage components of the car seat, making the massage components enter the working state and switching between multiple different massage control logics. The monitoring and capturing module can detect the seat surface through a contact pressure sensor to obtain the massage pressure and massage frequency transmitted by the massage components.

[0051] The monitoring and capturing module sends the massage pressure and massage frequency to the point analysis module. The point analysis module compares the massage pressure and massage frequency with the set massage pressure and massage frequency. If the massage pressure meets the set massage pressure, it generates a normal pressure adjustment signal. If the massage pressure does not meet the set massage pressure, it generates an abnormal pressure adjustment signal. If the massage frequency meets the set massage frequency, it generates a normal frequency adjustment signal. If the massage frequency does not meet the set massage frequency, it generates an abnormal frequency adjustment signal.

[0052] The massage detection module sends the abnormal frequency adjustment signal, abnormal pressure adjustment signal, normal pressure adjustment signal, and normal frequency adjustment signal to the result input unit.

[0053] After the result input unit simultaneously obtains the normal pressure adjustment signal and normal frequency adjustment signal, it generates a qualified massage detection signal. When obtaining any one group of the abnormal frequency adjustment signal and abnormal pressure adjustment signal, it generates an unqualified massage detection signal. Embodiment

[0054] Please refer to Figure 1 - Figure 2 As shown in the figure, when the result input unit simultaneously generates a qualified massage detection signal and a qualified ventilation detection signal, it sends a detection completion instruction to the production line control unit.

[0055] When the result input unit generates an unqualified massage detection signal or an unqualified ventilation detection signal, it sends a re-inspection instruction to the circulation control unit and marks the currently detected car seat. The circulation control unit sends a detection instruction to the ventilation detection module and the massage detection module again, so that the ventilation detection module and the massage detection module detect the marked car seat again.

[0056] When the result input unit obtains the massage detection unqualified signal or the ventilation detection unqualified signal for the marked car seat again, it sends a detection completion instruction to the production line control unit, and at the same time records the car seat as an unqualified seat, and sends the recorded seat number to the management platform through the network.

[0057] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation manners. Obviously, many modifications and variations can be made according to the content of this specification.
