[0023] The technical solution of the utility model is described in detail below with reference to the accompanying drawings:

[0024] like Figure 1-Figure 4 As shown, a weight-variable seat noise detection device includes a weight-variable flexible tooling and a noise detection platform that cooperate with each other. The noise detection platform includes a detection base 14 arranged on the upper part of a support base, at least two groups of second guide shafts 16 are arranged on the detection base 14, a matching noise detection lifting cylinder 17 is arranged on the upper part of each group of second guide shafts 16, and a noise detector 22 is arranged on the upper part of the noise detection lifting cylinder 17; a tray lifting cylinder 25 is arranged in the middle part of the detection base 14, a socket tooling 23 is arranged on the upper part of the tray lifting cylinder 25, and a plurality of pins 24 are arranged on the socket tooling 23.

[0025] like Figure 4 As shown, a seat fixing and pushing-out cylinder 13 is arranged on the outer periphery of the detection base 14 of the utility model through a supporting column, a seat fixing cylinder 12 is arranged on the upper part of the seat fixing and pushing-out cylinder 13, and a seat fixing tool 11 is arranged at the output end of the seat fixing cylinder 12; the seat fixing tool 11 is used to fix the car seat placed on the tray.

[0026] like Figure 2 , Figure 3 As shown, the variable-weight flexible tooling of the utility model includes a second lower pressure plate located on the upper part of the car seat, a deep groove ball bearing 9 and a swing mechanism 10 are respectively arranged at the lower part of the second lower pressure plate, a lower pressure mechanism 8 is arranged between the deep groove ball bearing 9 and the second lower pressure plate; a weight block 7 is arranged on the upper end surface of the second lower pressure plate.

[0027] like Figure 2 , Figure 3 As shown, the first lower pressing plate is arranged on the upper part of the second lower pressing plate of the utility model, a plurality of columns and a plurality of flexible belts 5 are arranged between the second lower pressing plate and the first lower pressing plate, a floating joint 3 and a first guide shaft 2 are respectively arranged on the upper end surface of the first lower pressing plate, and a matching lower pressing cylinder 1 is arranged on the upper end part of the floating joint 3.

[0028] like Figure 4 As shown, the second guide shaft 16 of the present invention slides in the second linear bearing 18 .

[0029] like Figure 2 As shown, the first guide shaft 2 of the utility model slides in the first linear bearing 4.

[0030] like Figure 2 As shown, the weight block 7 of the utility model is fixed on the second lower pressing plate through the weight positioning column 6.

[0031] like Figure 4 As shown, a shock-absorbing pad 15 is arranged between the supporting base and the detecting base 14 of the utility model.

[0032] A weight-variable seat noise detection device, when in use, the car seat on the pallet is sent into the detection device by the conveyor line, and when the pallet reaches the position, the pallet lifting cylinder 25 performs the lifting work to lift the pallet to the designated position, during which the pallet positioning column 19 will accurately position the pallet, and when the car seat on the pallet reaches the designated position, the two seat fixing and pushing cylinders 13 perform the pushing work, and after reaching the designated position, the two seat fixing cylinders 12 synchronously return to the state, driving the two seat fixing cylinders 11 to fix the car seat at the same time, ensuring that the car seat will not tilt. At this time, the pressing cylinder 1 extends out, and the guide shaft 2 slides in the linear bearing 4. The deep groove ball bearing 9 on the pressing mechanism 8 is pressed on the car seat, and the swing mechanism 10 is also pressed on the car seat, and is completely fitted with the car seat through its own swing. At this time, the eight belts 5 are in a completely relaxed state and are not affected by any external force. In this way, the weight of the weight block 7 will be fully applied to the seat, imitating the weight of the human body sitting on the seat. The weight block 7 is fixed by the weight positioning column 6, and the weight block 7 can be increased or decreased according to the demand. When the pressing cylinder 1 is in place, the noise detection lifting cylinder 17 is lifted, and the noise detector 22 is sent to the detection position. When the noise lifting cylinder 17 is in place, it is pushed out by the socket cylinder, and the socket tooling 23 is inserted into the seat. At this time, the pin 24 is used to identify the car seat model, and the car seat is powered on to allow it to vibrate itself. At this time, the weight block 7 and the flexible belt 5 are completely free of force, simulating the weight of the human body on the car seat. During the vibration, the car seat will drive the detection base 14 to vibrate together. At this time, the shock-absorbing pad 15 reduces the vibration of the detection base 14 and reduces the noise outside the seat. The micro shock-absorbing pad 21 under the noise detector 22 will also reduce the noise outside the seat, and more clearly measure the noise generated only by the car seat to determine whether the car seat noise detection is qualified. After the detection is completed, the socket tooling 23 is powered off and returns to its original position. The car seat is no longer vibrating, the noise detection lifting cylinder 17 is retracted, and the noise detector 22 is brought to a safe position. The pressing cylinder 1 is retracted, and the weight block 7 simulating the weight of the human body and the belt 5 are completely separated from the car seat. At this time, the belt 5 is in a tensioned state. When the pressing cylinder 1 is retracted to its position, the two seat fixing cylinders 12 are simultaneously pushed out and no longer fix the car seat. After the seat fixing cylinder 12 is in place, the seat fixing push-out cylinder 13 is in the return state. After the seat fixing push-out cylinder 13 is in place, the pallet lifting cylinder 25 returns to its original position. At this time, the pallet positioning column 19 is completely separated from the pallet. At this time, the pallet will be placed on the conveyor line, and the conveyor line will output in the reverse direction, so that the car seat on the pallet leaves the noise detection equipment and proceeds to the next process.

[0033] The utility model uses a flexible belt structure to better exert the force on the object under force, and uses a rubber shock-absorbing structure to further reduce the influence of non-detection noise.

[0034] The utility model uses a weight block to simulate the load-bearing capacity of a car seat, adopts a design concept of variable weight, increases the compatibility of equipment, and can make the equipment compatible with more product tests; at the same time, an electrical detection function is used to realize automatic identification of product models.
