Mark in the content expressed every width accompanying drawing in instructions of the present invention below and figure is briefly described:
Fig. 1 is the cushion abnormal sound on-line detecting system structural representation of automotive seat;
Mark in above-mentioned figure is: 101, the first microphone; 102; First slide; 103, the first push-and-pull hydraulic cylinder; 104, lifting hydraulic cylinder; 105, holder; 106, connecting rod; 107, briquetting; 108, counterweight; 109, guidepost; 110, laser induced mechanism.
Embodiment
The cushion abnormal sound on-line detecting system of automotive seat is arranged on automobile assembly line, need to be arranged on seat be installed and do not install on one section of production line of car door, owing to being the detection to abnormal sound (sound), therefore automobile assembly line is provided with a section of this system and is positioned at airtight quiet cabin, automobile assembly line is provided with the transmission system of automatic transportation automobile, the front and back in quiet cabin are provided with the cabin door for automobile turnover, after automobile automatic transportation to be detected to the desired location in quiet cabin, detect, automatically quiet cabin is transported again afterwards, cabin door is then closed automatically when detecting, and automatically open when Automobile Transportation.The necessary sound insulation in quiet cabin, avoiding external noise to impact testing result, for guaranteeing sealing property, being provided with sealing joint strip between hatch door and quiet cabin.
The cushion abnormal sound on-line detecting system of automotive seat is provided with the guide rail vertical with automobile assembly line in automobile assembly line symmetria bilateralis, can detect two automotive seats of automobile with row respectively, and detect front-row seats of vehicle and back seat according to this, as shown in Figure 1, guide rail is provided with the first slide 102, first slide 102 can along slide, first slide 102 drives along slide by the first push-and-pull hydraulic cylinder 103, first slide 102 is vertically provided with lifting hydraulic cylinder 104, lifting hydraulic cylinder 104 is supported with holder 105, lifting hydraulic cylinder 104 can control holder 105 and rises or decline.The front-end and back-end of holder 105 respectively level are provided with the connecting rod 106 with guide rail parallel, briquetting 107 is provided with near connecting rod 106 end of automobile assembly line side, another connecting rod 106 end winding support has counterweight 108, briquetting 107 sits on for simulating passenger or driver the state (jolt when vehicle travels and produce moving up and down of passenger) that cushion moves up and down, counterweight 108 for balanced system, and can coordinate the weight increasing briquetting 107 and exert pressure on cushion.For avoiding causing damage to automobile seat cushion cortex, avoid producing noise jamming because rubbing with cortex, briquetting 107 is wrapped with flannelette napped fabric layer, is filled with soft inserts, as soft rubber between flannelette napped fabric layer and briquetting 107 simultaneously.
For ensureing the stable of system physical structure further, the first slide 102 is vertically fixed with guidepost 109, and holder 105 is provided with the pilot hole matched with guidepost 109.The guidance system that such guidepost 109 and pilot hole are formed can ensure the stable of top briquetting 107 and counterweight 108, reduces the impact on lifting hydraulic cylinder 104.
In order to gather after cushion is extruded by briquetting 107 whether can produce abnormal sound, the first microphone 101 be fixed on connecting rod 106 is provided with on briquetting 107 side, first microphone 101 can by soft and have the Metallic rod of certain toughness to be fixed on above briquetting 107 or side, like this, first microphone 101 is when gathering sound, be positioned at pilothouse, can gather more accurately.
System is controlled by control module, and the first microphone 101 exports induced signal to control module, and control module outputs control signals to the oil pump driver element of the first push-and-pull hydraulic cylinder 103 and lifting hydraulic cylinder 104, thus controls whole system work.
Preferred version, briquetting 107 lower surface is provided with pressure transducer, pressure transducer outputs signal to control module, form closed-loop control, what then control module accurately can control briquetting 107 presses down strength (caning be controlled in 200-300 jin pressure), ensures reliability and the accuracy of testing result.
Preferred version, holder 105 both sides are provided with laser induced mechanism 110, the laser induced mechanism 110 being positioned at automobile assembly line side receives the laser signal of the laser induced mechanism 110 of automobile assembly line opposite side, the laser induced mechanism 110 of automobile assembly line both sides is needed to cooperatively interact, briquetting 107 is then needed to be less than the width of holder 105, the laser induced mechanism 110 matched like this can carry out responding to (Emission Lasers and reception laser), installing this device is in order to avoid the conveying arrangement of automobile assembly line can accurately not stop automobile, and cause briquetting 107 to failing during moving vehicle to move to above automotive seat, but arrive to automobile frame, and cause system failure, if the laser induced mechanism 110 matched can receive signal, then represent that briquetting 107 can safe displacement, can not cause and have an accident.
In addition, the touch screen be connected with control module is provided with outside quiet cabin, touch screen display and input parameter information, the work times, dynamics etc. of such as briquetting 107, control module is connected with computer, and the data of reception are delivered to computer, more complicated analytic process can be carried out by computer, draw more accurately testing result (acoustic processing can be programmed as required, such as can be detected by the amount in decibels of sound, or detected by wave-shape amplitude), in addition, computer can also store the data message received.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
