DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Specific examples are given below.
[0025] like Figures 1 to 5 As shown, a vibration detection device for seat testing described in an embodiment of the utility model comprises a fixing plate 1; a frame 11 is fixedly connected to the side wall of the fixing plate 1; a bidirectional screw 12 is rotatably connected to the frame 11; a pair of sliders 13 are threadedly connected to the bidirectional screw 12; a clamping plate 14 is fixedly connected to the side wall of the slider 13; a rotating rod 15 is fixedly connected to the end of the bidirectional screw 12; a connecting assembly is provided on the side wall of the fixing plate 1; a support seat 16 is installed on the connecting assembly; and a vibration sensor body 17 is installed on the support seat 16. When performing vibration detection on a car seat, the vibration detection device is fixed on the frame of the seat, and the vibration sensor body 17 is brought into contact with the part to be tested on the seat. The vibration sensor body 17 is used to collect the vibration signal of the seat. The vibration sensor body 17 is connected to an external host device through a cable, and then the signal collected by the vibration sensor body 17 is analyzed in conjunction with the detection software program to determine whether the seat meets the test requirements. When the vibration detection device is fixed on the car seat, the clamping plate 14 is located on both sides of the seat frame, and then the rotating rod 15 is rotated to drive the bidirectional screw 12 to rotate. At this time, the sliders 13 inside the frame 11 will move toward each other, and the sliders 13 will drive the clamping plates 14 to move toward each other. When the bidirectional screw 12 rotates and drives the clamping plates 14 to approach each other, the clamping plates 14 can be clamped and fixed on the seat frame after contacting the seat, so that the position of the vibration detection device is fixed. In summary, by setting the fixing plate 1, the bidirectional screw 12 and the clamping plate 14, it is convenient to fix the support seat 16 and the vibration sensor body 17 on the frame of the car seat, and this method is used to fix them more securely. At the same time, by adjusting the bidirectional screw 12, the clamping plate 14 can be driven to move different distances, which can adapt to seats of different sizes to improve the versatility of the vibration detection device.
[0026] like Figure 1 as well as Figure 4 As shown, the first rotating disk 2 is fixedly connected to the rotating rod 15; the first rotating disk 2 is provided with a plurality of first fixing holes 21; the fixing plate 1 is provided with a second fixing hole 23 on the side facing the first rotating disk 2; the first rotating disk 2 is fixed by inserting the latch 22 into the first fixing hole 21 and the second fixing hole 23. During operation, after the clamping plate 14 is clamped and fixed on the seat frame, and a first fixing hole 21 on the first rotating disk 2 is aligned with the second fixing hole 23 on the side wall of the fixing plate 1, the latch 22 is inserted into the first fixing hole 21 and the second fixing hole 23, and the first rotating disk 2 can be fixed on the fixing plate 1, and the first rotating disk 2 will fix the position of the rotating rod 15 and the bidirectional screw 12. In summary, by setting the first turntable 2, the first fixing hole 21 and the second fixing hole 23, and using the pin 22, after the splint 14 is fixed to the seat frame, the position of the first turntable 2 and the bidirectional screw 12 can be fixed by the pin 22, so as to avoid the situation in which the bidirectional screw 12 rotates due to vibration during detection, causing the splint 14 to loosen, thereby affecting the fixing effect of the vibration sensor body.
[0027] like Figure 1 , Figure 2 and Figure 5 As shown, the connection assembly includes a pair of fixing seats 3; the pair of fixing seats 3 are fixedly connected to the side walls of the support seat 16 and are symmetrically distributed; a support rod 31 is rotatably connected to the fixing seat 3; the two side walls of the support rod 31 are fixedly connected to the second turntable 32; one of the second turntables 32 is provided with a plurality of third fixing holes 33; a spring pin 34 is slidably connected to the fixing seat 3 near the third fixing hole 33; the spring pin 34 can be inserted into the third fixing hole 33. After the vibration detection device is installed on the seat, if the angle of the vibration sensor body 17 needs to be adjusted, the spring pin 34 is pulled to disengage it from the third fixing hole 33, and then the support seat 16 is rotated to drive the fixing seat 3 to rotate. When it is rotated to a suitable position, the spring pin 34 is released to allow the spring pin 34 to rebound and be inserted into the third fixing hole 33, thereby fixing the position of the fixing seat 3 and the support seat 16. In summary, by setting the fixing seat 3, the support rod 31 and the second turntable 32, in conjunction with the spring pin 34 and the third fixing hole 33, the angle of the vibration sensor body 17 can be easily adjusted during use, so that the vibration sensor body 17 can be adjusted to contact the part to be tested on the seat.
[0028] like Figure 3As shown, a slide groove 4 is provided on the clamping plate 14; a card plate 41 is rotatably connected in the slide groove 4; the card plate 41 is in an L-shaped structure; a torsion spring is provided at the connection between the card plate 41 and the clamping plate 14. In the process of installing the vibration detection device on the seat, the card plate 41 may contact the surface of the seat. Since the card plate 41 is rotatable, the card plate 41 will not make hard contact with the surface of the seat and cause the seat to be scratched. When the vibration detection device is installed in place, the card plate 41 will be reset under the action of the torsion spring, and the card plate 41 will hook the back of the seat frame. In summary, by providing the slide groove 4 and the card plate 41, when the clamping plate 14 is clamped and fixed on the seat frame, the card plate 41 can hook the back of the seat frame, thereby improving the clamping stability of the clamping plate 14.
[0029] like Figure 3 As shown, a pair of the clamping plates 14 are fixedly connected to a rubber pad on one side thereof close to each other. When the clamping plates 14 are clamped and fixed on the seat frame, the rubber pad 5 will contact the surface of the seat frame. The rubber pad 5 can reduce the squeezing force between the clamping plates 14 and the seat frame, and at the same time increase the friction between the clamping plates 14 and the seat frame, thereby improving the clamping stability of the clamping plates 14.
[0030] like Figure 4 As shown, a drawstring 7 is fixedly connected to the side wall of the fixing plate 1; the end of the drawstring 7 is connected to the latch 22. During operation, when the latch 22 is taken out, the drawstring 7 will pull the latch 22, so that the latch 22 can be hung on the side wall of the fixing plate 1. By providing the drawstring 7 to connect the latch 22 and the fixing plate 1, the latch 22 can be stored conveniently, so as to reduce the possibility of the latch 22 being lost.
[0031] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
