Description

Technical Field

[0001] The utility model relates to the technical field of dynamic impact testing equipment for toy vehicles. Background Art

[0002] In actual use scenarios, it is foreseeable that children will have accidents while operating toy cars while playing. When accidents occur, toy cars hit common obstacles on the ground such as steps, thresholds, stones, etc., causing the front wheel to break or fall off, resulting in mechanical failure, which accounts for the vast majority of cases. The above-mentioned failure of the physical strength of riding toys in dynamic use can lead to the falling of children's roller skate wheels, the breaking of scooter steering rods, and the falling of parts, which may cause children to fall suddenly. The injuries or even fatal accidents caused by broken parts stabbing children have prompted toy standards in various countries to have strict requirements for the dynamic impact performance of riding toys. Therefore, it is necessary to conduct quality testing on riding toys entering the market to determine the quality of products during their use period and ensure their safety.

[0003] In response to this market demand, the applicant developed a dynamic impact performance testing device for ride-on toys in 2019, patent number CN201921059797.7.

This device can meet the testing requirements of different types of ride-on toys. However, after extensive and long-term testing, the applicant discovered that the device had some shortcomings in terms of stability. Utility Model Content

[0028] The speed sensor 9 and the power-off sensor 10 are respectively arranged above the synchronous belt linear guide 6, the speed sensor 9 is located in the middle section of the synchronous belt linear guide 6, and the power-off sensor 10 is located between the impact block 11 and the speed sensor 9; the balancing guide rail 12 is an aerial guide rail, which is arranged directly above the dual synchronous belt linear guide 6; the traction slider 13 is arranged on the balancing guide rail 12 and is used to suspend the load weight; the servo motor 8, the speed sensor 9 and the power-off sensor 10 are electrically or signal-connected to the PLC control cabinet 14.

[0029] refer to Figure 2 This embodiment further provides a sample support rod 2 comprising a base plate 201, an adjustment plate 202, and a tree-shaped rod 203. The adjustment plate 202 is vertically fixed to the base plate 201 and has an arc-shaped long waist hole 202a. The bottom of the tree-shaped rod 203 is connected to the adjustment plate 202 via a bolt passing through the long waist hole 202a. To more stably hang the sample, the sample support rods 2 are preferably arranged in pairs.

[0030] In order to keep the sample in a relatively stable state before it moves forward and hits the impact block, baffles 204 may be further provided on the outside of the two tree-shaped rods 203 .
