Structural stability testing of children's toy vehicles

Structural stability testing of children's toy vehicles (such as electric toy cars, pedal toy cars, push-pull toy cars, etc.) is a core component in ensuring the safety of children's use, and must strictly adhere to international or national toy safety standards (such as China's GB 6675, the EU's EN 71, and the US's ASTM F963, etc.).

The structure serves as the “framework” of the toy vehicle, and must ensure that it does not break, deform, or overturn during children's play activities (such as riding, pushing/pulling, or colliding), thereby preventing risks such as crushing or falling.

For rideable toy vehicles (such as children's electric four-wheelers), simulate the weight of a child (typically based on the standard-specified “maximum load capacity,” such as 20–50 kg) by applying static loads to critical components like seats and footrests and maintaining the load for a specified duration (e.g., 10–30 minutes). The test evaluates whether the structure deforms, fractures, or if fasteners (such as screws or rivets) become loose.

Purpose: To prevent children from falling or sustaining compression injuries due to structural collapse while riding.

Simulate collisions that may occur during toy car use (such as hitting walls or furniture). Collide the toy car with a rigid obstacle at a specified speed (e.g., 3–5 km/h), or allow a dummy of a certain weight to fall from the seat. Test whether the car body, frame, guardrail, and other parts are cracked, and whether sharp edges or fragments are produced.

Purpose: To verify the structure's ability to withstand impacts during unexpected collisions and prevent component fractures that could cause cuts.

Test the toy car's ability to resist overturning when tilted, turning, or subjected to force on one side:  

Place the toy car on a plane with an increasing tilt angle (e.g., from 10° to 30°) and observe whether it overturns;  

For steerable toy cars, simulate the centrifugal force during a sharp turn to test whether it overturns.  

Purpose: Prevent children from falling and getting injured due to the toy car overturning during play.

For toy vehicles with folding functions (such as folding bicycles), test whether the locking device of the folding mechanism is secure: apply a specified force (such as 50-100N) to attempt to unlock it, and observe whether it accidentally loosens; repeatedly fold and unfold it multiple times (such as 50-100 times) to test whether the locking device fails.

Purpose: To prevent sudden unlocking of the folding structure from causing finger or body injuries to children.
