As shown in fig. 1 and 2, the utility model discloses a baby stroller walking test device to detect the performance of the running gear of baby stroller 100, the test device in this embodiment includes test board 1, obstacle collision belt 22, recorder and anomaly detection device. The testing machine 1 is provided with a supporting platform 200 formed by a conveyor belt 20, the supporting platform 200 is used for placing the baby stroller 100 to be tested, when the baby stroller 100 is fixed on the supporting platform 200, the wheels are driven to rotate along with the operation of the conveyor belt 20, and therefore, the supporting platform 200 simulates a moving road surface. The edge of the supporting table 200 is provided with a fixing rod 3 for fixing the stroller 100, and the fixing rod 3 is detachably connected to the stroller 100 by a connecting member 4, so that the stroller 100 is stably fixed on the supporting table 200. The barrier collision belt 22 is transversely disposed on the conveyor belt 20, and the barrier collision belt 22 passes through the front and rear wheels of the stroller 100 once per one rotation of the conveyor belt 20 to collide with the front and rear wheels. The recording device is used to record the length of time the stroller 100 is tested under normal conditions and/or the number of collisions with the obstacle collision belt 22. The abnormality detecting device includes a pair of area sensors 50 provided at the rear end of the support table 200, the area sensors 50 detecting whether a falling obstacle is generated on the support table 200, and the rotation of the conveyor belt 20 is stopped when the area sensors 50 are triggered. The pair of area sensors 50 are respectively installed at both sides of the support table 200, and the light curtain of the pair of area sensors 50 can cover the entire width area of the support table 200.

The utility model discloses baby's shallow walking testing arrangement's working process does: as shown in fig. 1, firstly, the stroller 100 is placed on the supporting platform 200, and then the stroller 100 is fixed by the connecting member 4 connected to the fixing rod 3 so as to be fixed on the supporting platform 200, thereby preventing the stroller from shifting during the test, and then the driving motor 21 of the conveyor belt 20 is turned on, so that the conveyor belt 20 starts to rotate circularly, and the wheels are driven to rotate in situ along with the rotation of the conveyor belt 20, thereby achieving the purpose of testing the performance of the walking mechanism. During the operation of the conveyor belt 20, the barrier impact belt 22 collides with the front and rear wheels of the stroller 100 once every time the conveyor belt 20 runs for one circle, i.e., the barrier impact belt 22 passes under the front and rear wheels once, respectively, to simulate the collision avoidance performance of the wheels. In the test process, if the wheels or other parts and other objects fall off, the objects are conveyed to the rear end of the supporting table top 200 by the conveyor belt 20, the area sensor 50 is triggered, then the conveyor belt 20 stops acting, so that the phenomenon that the frame or the falling objects scratch the conveyor belt 20 is avoided, and as the area sensor 50 can cover the whole width range of the supporting table top 200, the missed detection of the falling objects can be avoided, the sensing time of the area sensor 50 is short, and the anti-interference capability is strong, so that the normal operation of the infant test device is ensured. The area sensor 50 in this embodiment is a safety light curtain, and a common light curtain or a measurement light curtain may be used as an option, i.e., the specific choice of the area sensor 50 is not limited as long as the sensor has a function of detecting an object in a specific area space. In the above-mentioned testing process, the recording device can record the testing duration of the stroller 100 under normal conditions, and also record the number of collisions between the obstacle collision belt 22 and the wheels, so as to provide detection data for the test report of the running mechanism of the stroller 100.
