Embodiment
The cushion abnormal sound on-line detecting system of automotive seat is arranged on automobile assembly line, it is necessary to installed in mounting seat
Chair and do not install on one section of production line of car door, due to being the detection to abnormal sound (sound), therefore automobile assembly line is provided with this
One section of system is in closed Jing Yin cabin, and automobile assembly line is provided with the Transmission system of automatic transportation automobile, Jing Yin cabin
The front and rear cabin door provided with the disengaging of steam supply car, after automobile automatic transportation to be detected to the setting position in Jing Yin cabin, progress
Detection, transport Jing Yin cabin automatically again afterwards, and cabin door is then closed automatically in detection, and beaten automatically in Automobile Transportation
Open.Jing Yin cabin must sound insulation, avoid external noise from impacting testing result, to ensure sealing property, hatch door with it is Jing Yin
Sealing joint strip is provided between cabin.
The cushion abnormal sound on-line detecting system of automotive seat is arranged with automobile assembly line both sides to hang down with automobile assembly line
Straight guide rail, automobile can be detected with two automotive seats of row respectively, and detect front-row seats of vehicle according to this with after
Seat is arranged, as shown in figure 1, being provided with first slide 102 on guide rail, first slide 102 can be slided along guide rail, first slide
102 are slided by the drives edge guide rail of the first push-and-pull hydraulic cylinder 103, and lifting hydraulic cylinder 104 is provided with vertically in first slide 102, are lifted
Fixed seat 105 is supported by hydraulic cylinder 104, lifting hydraulic cylinder 104 can control fixed seat 105 to rise or decline.Fixed seat 105
The front-end and back-end horizontal connecting rod 106 being provided with guide rail parallel respectively, set close to the end of connecting rod 106 of automobile assembly line side
There is briquetting 107, another end of connecting rod 106 is fixed with counterweight 108, and briquetting 107 is used to simulate passenger or driver sits on cushion
The state (vehicle jolts when travelling produces the up and down motion of passenger) of upper up and down motion, counterweight 108 is used for balance system, and energy
It is enough to coordinate increase briquetting 107 to press the weight onto cushion.To avoid causing damage to automobile seat cushion cortex, avoid simultaneously
Noise jamming is produced because being rubbed with cortex, briquetting 107 is wrapped with flannelette napped fabric layer, filled with soft between flannelette napped fabric layer and briquetting 107
Inserts, such as soft rubber.
To be further ensured that the stabilization of system physical structure, lead 109 is vertically fixed in first slide 102, Gu
Reservation 105 is provided with the pilot hole being engaged with lead 109.The guidance system that so lead 109 and pilot hole are formed
The stabilization of top briquetting 107 and counterweight 108 can be ensured, reduce the influence to lifting hydraulic cylinder 104.
Whether abnormal sound can be produced after cushion is extruded by briquetting 107 in order to gather, the company of being fixed on is provided with the side of briquetting 107
The first microphone 101 on bar 106, the first microphone 101 can be fixed on pressure by metallic rod that is soft and having certain toughness
The top of block 107 or side, so, the first microphone 101 in driver's cabin, can be adopted more accurately when gathering sound
Collection.
System is controlled by control unit, and the first microphone 101 exports induced signal to control unit, control unit output control
Signal processed is to the first push-and-pull hydraulic cylinder 103 and the oil pump driver element of lifting hydraulic cylinder 104, so as to control whole system to work.
Preferred scheme, the lower surface of briquetting 107 are provided with pressure sensor, and pressure sensor outputs signal to control unit, structure
Into closed-loop control, then control unit can accurately control the lower amount of pressure (caning be controlled in 200-300 jin pressure) of briquetting 107, protect
Demonstrate,prove the reliability and accuracy of testing result.
Preferred scheme, the both sides of fixed seat 105 are provided with laser induced mechanism 110, the laser sense positioned at automobile assembly line side
Mechanism 110 is answered to receive the laser signal of the laser induced mechanism 110 of automobile assembly line opposite side, it is necessary to swashing for automobile assembly line both sides
Photoinduction mechanism 110 cooperates, then needs briquetting 107 to be less than the width of fixed seat 105, the laser induced machine being so engaged
Structure 110 can be sensed (transmitting laser and reception laser), and it is the transport in order to avoid automobile assembly line to install this device
Device can accurately not stop automobile, and fail when causing briquetting 107 to move to automobile to move to above automotive seat, but support
To automobile frame, and system failure is caused, if the laser induced mechanism 110 being engaged can receive signal, then it represents that briquetting
107 can safe displacement, will not cause that accident occurs.
In addition, Jing Yin cabin is externally provided with the touch screen being connected with control unit, touch screen is shown and input paramete information,
Such as the work times of briquetting 107, dynamics etc., control unit is connected with computer, and the data of reception are delivered into computer, is passed through
Computer can carry out more complicated analysis process, show that (acoustic processing can compile more accurate testing result as needed
Journey, such as can be detected by the amount in decibels of sound, or detected by wave-shape amplitude), in addition, computer can also store receipts
The data message arrived.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
