Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive testing technology, and in particular to a testing device for the massage and ventilation functions of automotive seats. Background Technology
[0002] Car seat massage and ventilation function testing refers to a comprehensive test of the functionality, safety, and reliability of the massage and ventilation system equipped in a vehicle seat. This testing typically includes: verifying whether the ventilation fan operates normally, whether the airflow is uniform, and whether the temperature control is accurate; checking whether the massage motor or pneumatic device can work according to preset modes, and whether the intensity and rhythm meet design requirements; and also evaluating the control system's responsiveness, fault self-diagnosis capabilities, and stability under different environmental conditions.
[0003] Currently, the testing of massage and ventilation functions in car seats primarily relies on manual touch, a method with significant limitations. Manual testing is highly dependent on the operator's subjective perception; individual differences in perception of "massage intensity," "airflow strength," or "temperature changes" lead to inconsistent and unrepeatable results. Secondly, in mass production or quality inspection processes, manual testing is inefficient and cannot meet the demands of modern, fast-paced, and high-precision automotive manufacturing. Furthermore, human judgment is susceptible to factors such as fatigue and emotions, easily leading to missed inspections, misjudgments, or even incorrect inspections. This not only affects product quality control but may also cause after-sales issues and customer complaints. Summary of the Invention

The first air pressure sensor is used to detect the air pressure change data after inflation.
[0014] The bottom detection assembly further includes a stabilizing base, which is fixedly connected to the first disc body and rotatably connected to the lifting base.
[0015] The back detection assembly includes a longitudinal fine-tuning block, a lateral fine-tuning block, a second disc, and a second air pressure sensor.

Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0031] Please see Figures 1 to 7 This invention provides a car seat massage and ventilation function testing device, including a support frame 101, a seat limiting component 102, a positioning component 103, a ventilation detection component 104, and multiple massage force detection heads 105. The seat limiting component 102 is disposed on the support frame 101 and is used to limit the seat moving to a designated position on the conveyor line. The positioning component 103 includes a lateral moving member 106, a longitudinal moving member 107, and a lifting seat 108. The lateral moving member 106 is slidably disposed on the top of the support frame 101, and the longitudinal moving member 107 is slidably disposed on the top of the support frame 101. The lifting seat 108 is mounted on the longitudinal moving member 107 on the lateral moving member 106; the ventilation detection assembly 104 includes a bottom detection assembly 109 and a back detection assembly 110. The bottom detection assembly 109 is mounted on the bottom of the lifting seat 108 and is used to detect the ventilation performance of the bottom of the seat. The back detection assembly 110 is mounted on one side of the lifting seat 108 and is used to detect the ventilation performance of the back of the seat. A plurality of massage force detection heads 105 are mounted on one side of the back detection assembly 110 and are used to detect the massage force of the seat.
[0032] In this embodiment, the support frame 101 serves as the basic framework of the entire testing device. Made of high-strength rigid material, it possesses excellent stability and load-bearing capacity, supporting and integrating the remaining functional modules. The seat limiting component 102 is fixedly installed on the support frame 101. Its function is to precisely limit and fix the car seat as it moves along the conveyor line to the preset testing station, preventing seat shaking or displacement from affecting the accuracy of the test results during the testing process. The positioning component 103 is located on the top of the support frame 101, used to precisely adjust the position of the testing component relative to the seat, ensuring that the testing probe can accurately align with the area to be tested on the seat. The positioning component 103 includes a lateral moving part 106, a longitudinal moving part 107, and a lifting seat 108: the lateral moving part 106 slides horizontally along the top of the support frame 101, enabling left-right position adjustment; the longitudinal moving part 107 is slidably installed on the lateral moving part 106 for precise front-back positioning; the lifting seat 108 is fixed on the longitudinal moving part 107 and can move up and down to adapt to different seat heights, achieving flexible positioning in three-dimensional space. The ventilation detection assembly 104 consists of two parts: a bottom detection assembly 109 and a back detection assembly 110. The bottom detection assembly 109 is mounted on the bottom surface of the lifting seat 108, conforming to the seat cushion area. Through built-in airflow sensors and pressure sensors, it collects and analyzes in real time the airflow volume, wind speed uniformity, and airflow distribution of the ventilation holes at the bottom of the seat. The back detection assembly 110 is located on one side of the lifting seat 108, facing the seat back. It is also equipped with corresponding sensing units to detect the ventilation performance of the backrest area, ensuring that the ventilation system functions normally in different areas. Multiple massage force detection heads 105 are arranged on one side of the back detection assembly 110, preferably a retractable miniature pressure sensor array. These heads can simulate the contact state of the human back and, when the seat activates the massage function, collect in real time the pressure values, frequency, stroke, and force change curves applied at each massage node. This comprehensively evaluates whether the working performance of the massage mechanism meets design standards, enabling automated seat detection and improving work efficiency.
[0033] The support frame 101 includes a frame body 111, foot pads 112, and a stabilizing block 113. The foot pads 112 are fixed on the frame body 111, and the stabilizing block 113 is disposed on one side of the frame body 111.
[0034] The frame 111 is constructed from high-strength steel or aluminum alloy profiles, welded or screwed together, forming a frame structure with excellent load-bearing capacity and resistance to deformation. The foot pads 112 are fixedly installed at the four corners of the bottom of the frame 111, preferably height-adjustable rubber or metal composite shock-absorbing foot pads 112, which can not only effectively absorb vibration interference caused by uneven ground, but also finely adjust the machine's level according to the on-site working conditions to ensure that the testing platform is in an ideal working posture. The stabilizing block 113 is set on one side of the frame 111 (usually near the conveyor line entrance or the operating side) to enhance the lateral stability of the support frame 101 under stress, prevent the whole machine from shaking due to the reaction force generated by seat positioning or testing actions, and further improve the reliability of system operation.
[0035] The seat limiting assembly 102 includes a first cylinder 114, a connecting block 115, and a positioning plate 116. The first cylinder 114 is fixed on the support frame 101. The connecting block 115 is connected to the output end of the first cylinder 114. The positioning plate 116 is detachably connected to the connecting block 115.
[0036] The first cylinder 114 is securely mounted on the frame 111 of the support frame 101 by bolts or other fastening methods, providing linear thrust as a drive source; one end of the connecting block 115 is hinged or rigidly connected to the piston rod output end of the first cylinder 114, and the other end is detachably connected to the positioning plate 116 (e.g., through quick-change buckles, threaded connectors or positioning pin structures), which facilitates the replacement of the appropriate positioning plate 116 according to different seat models, improving the versatility and ease of maintenance of the equipment; the side of the positioning plate 116 facing the seat can be designed with a contour-following structure according to the seat profile to achieve a more fitting and reliable limiting effect.
[0037] The seat limiting assembly 102 also includes a horizontal guide rod 117, and a guide seat 118 is provided on the frame 111. The horizontal guide rod 117 is fixed on the positioning plate 116 and is slidably connected to the guide seat 118.
[0038] A guide seat 118 is fixedly installed at a corresponding position on the frame 111 of the support frame 101. The guide seat 118 contains a linear bearing or sliding sleeve. One end of the horizontal guide rod 117 is rigidly fixed to the back of the positioning plate 116, and the other end passes through the guide seat 118, forming a sliding engagement with it. This design allows the positioning plate 116 to move smoothly along a predetermined straight path under the drive of the first cylinder 114, effectively preventing shaking, jamming, or tilting caused by cylinder thrust eccentricity or external interference, thereby ensuring the repeatability of the limit action and the reliability of long-term operation. Simultaneously, this guide structure also helps to distribute the lateral load borne by the cylinder, extending the service life of the pneumatic components.
[0039] The lateral moving component 106 includes a lateral cylinder 119, a first connecting block 120, and a lateral moving seat 121. The lateral cylinder 119 is fixed to the top of the frame 111. The first connecting block 120 is connected to the output end of the lateral cylinder 119. The lateral moving seat 121 is fixed to the first connecting block 120 and slidably disposed on the top of the frame 111.
[0040] The lateral moving component 106 serves as a key actuator for the positioning assembly 103 to achieve precise left-right (i.e., X-axis) positioning in the horizontal plane. Its structural design balances motion stability, load-bearing capacity, and repeatability. The lateral cylinder 119 is securely fixed to the top of the frame 111 of the support frame 101 by bolts or mounting brackets, providing linear thrust in the lateral direction as a power source. One end of the first connecting block 120 is rigidly connected to the piston rod output end of the lateral cylinder 119 (using a pin, flange, or threaded interface), while the other end is fixedly connected to the lateral moving seat 121 to transmit driving force and ensure a clear force flow path. The lateral moving seat 121 has a plate-like or frame-like structure, with a slider or linear guide pair at its bottom, forming a sliding fit with the guide rail or groove pre-installed on the top of the frame 111, thereby allowing for smooth and low-friction reciprocating movement along the top of the frame 111 under the drive of the lateral cylinder 119. This structure not only ensures high responsiveness and positioning accuracy in lateral movement, but also effectively supports the weight of the upper longitudinal moving part 107 and the detection components, preventing swaying or displacement during operation.
[0041] The longitudinal moving component 107 includes a longitudinal cylinder 122, a guide seat 118, and a vertical guide rod 124. The longitudinal cylinder 122 is fixed on the transverse moving seat 121. The guide seat 118 is connected to the output end of the longitudinal cylinder 122. The vertical guide rod 124 is fixed on the transverse moving seat 121 and is slidably connected to the guide seat 118.
[0042] The longitudinal cylinder 122 is mounted on the upper surface or side wall of the transverse moving seat 121 by fasteners, with its piston rod extending towards the seat under test. The guide seat 118 is fixedly connected to the output end (i.e., the piston rod end) of the longitudinal cylinder 122 and is used to support the back detection assembly 110, the lifting seat 108, and related sensing modules. To ensure that the guide seat 118 remains stable and does not twist or wobble during longitudinal movement, one or more vertical guide rods 124 (usually high-precision linear optical axes or chrome-plated guide posts) are also fixedly installed on the transverse moving seat 121. The vertical guide rods 124 are arranged perpendicular to the plane of the transverse moving seat 121 and pass through the corresponding linear bearings or sliding sleeves inside the guide seat 118, forming a precise sliding connection. Thus, when the longitudinal cylinder 122 extends or retracts, the guide seat 118 slides smoothly along the vertical guide rods 124 under the thrust of the cylinder, achieving precise displacement in the front-to-back direction. At the same time, the guide rods bear the lateral load, significantly improving the system rigidity and motion repeatability.
[0043] The bottom detection assembly 109 includes an adjustment block 125, a first disc 126, multiple air supply heads 127, and a first air pressure sensor 128. The adjustment block 125 is slidably disposed on one side of the lifting seat 108. The first disc 126 is fixedly connected to the adjustment block 125. The multiple air supply heads 127 are disposed on the first disc 126 for inflating after the first disc 126 is in close contact with the seat. The first air pressure sensor 128 is used to detect the air pressure change data after inflation.
[0044] The adjusting block 125 is slidably disposed on one side of the lifting seat 108. Its position can be adjusted in a direction perpendicular to the seat surface via a manual fine-tuning mechanism or an electric / pneumatic drive device to accommodate seat cushions of different thicknesses or shapes, ensuring that the first disc 126 can fully conform to the seat ventilation area during subsequent testing. The first disc 126 is fixedly connected to the adjusting block 125 and has an overall contoured plate structure. Its side facing the seat can be optimized according to the common seat cushion ventilation hole layout, with a flat surface and a certain degree of flexible sealing edge (such as a silicone sealing ring or a soft cushioning pad) to form a locally sealed chamber upon contact, preventing gas leakage from affecting the testing accuracy.
[0045] Multiple air supply heads 127 are integrated on the first disc 126. These air supply heads 127 are arranged in a preset array, corresponding to the common ventilation outlet positions in the seat cushion. When the first disc 126 is pressed against the seat, the air supply system injects a constant flow of compressed air into each air supply head 127 synchronously or in sections through pipelines, simulating the air intake state when the seat ventilation system is working normally. At the same time, the first air pressure sensor 128 is embedded inside the first disc 126 or on the air supply pipeline to monitor the air pressure change data in the sealed chamber during inflation in real time. By analyzing parameters such as the air pressure rise rate, steady-state pressure value, and attenuation characteristics, it is possible to determine whether the seat cushion ventilation channel is unobstructed, whether the air resistance is normal, and whether there are defects such as blockages or leaks, thereby achieving a quantitative evaluation of the ventilation function.
[0046] The bottom detection assembly 109 also includes a stabilizing base 129, which is fixedly connected to the first disc body 126 and rotatably connected to the lifting base 108.
[0047] The stabilizing seat 129 is rigidly fixed to the first disc 126 and rotatably connected to the lifting seat 108 via a pivot, hinge, or universal joint structure. This design allows the first disc 126 to pitch or yaw slightly around the connection point when in contact with uneven or tilted seat surfaces, automatically adapting to the seat contour and preventing poor sealing or damage to the detection head due to rigid pressure. Simultaneously, the stabilizing seat 129 effectively disperses the reaction force generated during the detection process, reducing impact on the lifting seat 108 and the upper positioning assembly 103, thus improving the operational stability and service life of the entire detection system.
[0048] The back detection assembly 110 includes a longitudinal fine-tuning block 130, a transverse fine-tuning block 131, a second disc 132, and a second air pressure sensor 133. The longitudinal fine-tuning block 130 is slidably disposed on the lifting seat 108, and the transverse fine-tuning block 131 is slidably connected to the longitudinal fine-tuning block 130. The second disc 132 is disposed on the transverse fine-tuning block 131, and the second air pressure sensor 133 is disposed inside the second disc 132. A plurality of massage force detection heads 105 are disposed on the second disc 132.
[0049] The longitudinal fine-tuning block 130 is slidably disposed on the side of the lifting seat 108 (usually the side facing the seat back) and can be precisely adjusted in the vertical direction (i.e., the Z-axis direction). This fine-tuning block can be driven by a manual knob, a precision lead screw, or a miniature electric push rod to accurately align the detection component with the core area of the seat back ventilation and massage functions according to the height difference of the seat back, ensuring the consistency and completeness of the detection position.
[0050] The longitudinal fine-tuning block 130 is further slidably connected to the transverse fine-tuning block 131. The two are connected by a high-precision linear guide or dovetail groove structure to achieve a low-friction, high-rigidity sliding fit. The transverse fine-tuning block 131 can be slightly displaced along the horizontal direction (i.e., the Y-axis direction, perpendicular to the depth direction of the seat) to compensate for the left and right offset or local curvature changes of the backrest caused by different seat models, thereby improving the fit between the second disc 132 and the surface of the seat back.
[0051] The second disc 132 is fixedly mounted on the front end of the transverse fine-tuning block 131, and its contour can be optimized according to the ergonomic curve of the backrest of mainstream automobile seats. The side of the second disc 132 facing the seat is usually provided with a flexible sealing layer (such as silicone pad or foam material), which can form a local sealed chamber when in contact with the backrest, effectively preventing gas leakage and improving the accuracy of ventilation detection. At the same time, the surface of the disc is integrated with multiple massage force detection heads 105. These detection heads are preferably miniature pressure sensor arrays, which are embedded inside the disc according to a preset grid or massage node layout. They can collect key parameters such as pressure value, vibration frequency, action period and force distribution applied to the simulated position of the "human body" by the seat massage mechanism in real time, so as to comprehensively evaluate whether the performance of the massage function meets the design specifications.
[0052] The second pressure sensor 133 is also embedded inside the second disc body 132, and it is connected to the ventilation detection area on the surface of the disc body through an internal air passage. When the second disc body 132 is pressed against the back of the seat, the external air supply system injects test airflow into the ventilation channel of the backrest, and the second pressure sensor 133 monitors the air pressure changes in the sealed cavity in real time. By analyzing data such as steady-state pressure, response time, and airflow attenuation curve, it is possible to determine whether the backrest ventilation holes are unobstructed, whether the airflow is uniform, and whether there are any problems such as blockage or poor sealing.
[0053] The car seat massage and ventilation function detection device also includes an information processing terminal, which includes a data acquisition module 134, a judgment module 135, and a notification module 136. The data acquisition module 134 is used to acquire pressure data from the first pressure sensor 128 and the second pressure sensor 133, as well as massage data from the massage force detection head 105. The judgment module 135 is used to judge the state of the seat based on the pressure data and the massage data. The notification module 136 is used to send the seat state to a designated device.
[0054] The data acquisition module 134 collects key detection data from various sensing units of the device in real time via wired (e.g., RS485, CAN bus, Ethernet) or wireless (e.g., Wi-Fi, Bluetooth, industrial LoRa) communication. This includes: pressure change data of the seat cushion area during air supply measured by the first air pressure sensor 128; air pressure response data of the seat back area fed back by the second air pressure sensor 133; and multi-dimensional massage performance parameters such as massage intensity, frequency of action, stroke displacement, and pressure distribution map output by multiple massage force detection heads 105. This module features a high sampling rate, strong anti-interference capability, and multi-channel synchronous acquisition capability, ensuring the integrity and timeliness of the raw data and providing a reliable basis for subsequent analysis.
[0055] The judgment module 135, based on a preset quality judgment rule library, comprehensively analyzes and evaluates the pressure and massage data collected by the data acquisition module 134. For example, when the air pressure rise rate of the seat cushion or backrest is lower than the standard value, the steady-state pressure fluctuation exceeds the allowable range, or the force curve fed back by the massage force detection head 105 deviates from the design specifications, the judgment module 135 can identify potential defects in the seat such as ventilation blockage, air duct leakage, massage motor failure, airbag rupture, or abnormal control logic. Simultaneously, this module supports multi-level judgment logic—it can perform both "qualified / unqualified" binary judgments and output detailed fault type, location, and severity scores, facilitating quality traceability and process optimization.
[0056] The notification module 136 is responsible for timely and accurate push of the seat status information (including detection results, abnormal alarms, data summaries, or complete reports) generated by the judgment module 135 to designated devices or systems. These designated devices may include: production line PLC control systems, MES (Manufacturing Execution System), operator handheld terminals, workshop dashboard displays, or remote quality management platforms. The notification method supports diverse formats, such as audible and visual alarms, pop-up notifications, SMS / email alerts, and API data interface pushes, and can be configured with differentiated information content and response strategies according to different roles (such as quality inspectors, equipment maintenance personnel, and production supervisors). Furthermore, the notification module 136 also has log recording and data archiving functions; all detection results can be stored by time, workstation, vehicle model, etc., meeting the automotive industry's compliance requirements for product lifecycle quality traceability.
[0057] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
