Furthermore, during use, the adjustment precision is low, failing to accurately simulate test conditions under different usage scenarios, resulting in limited reference value of the test results.

[0004] In response to the problems raised in the above article, we propose a dynamic stability testing and collision testing machine for baby walkers. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a dynamic stability testing and collision testing machine for baby walkers, which can effectively solve the problems in the existing technology.

[0010] According to the above-mentioned dynamic stability test and collision test machine for baby walkers, a connecting frame is fixedly connected to the bottom of the mounting plate, a connecting rod is rotatably connected inside the mounting plate, and a rotating shaft one and a rotating shaft two are rotatably connected to both ends of the connecting rod, and a rubber ring is fixedly connected to one end of the rotating shaft two.

[0011] According to the above-mentioned dynamic stability test and collision test machine for baby walkers, the rubber ring is in contact with or separates from the turntable.

[0012] According to the above-mentioned dynamic stability test and collision test machine for baby walkers, a threaded rod is rotatably connected inside the top plate, a slider is threadedly connected to the outside of the threaded rod, a traction rope is provided at the bottom of the slider, a traction hook is fixedly connected to one end of the traction rope, a stepper motor is fixedly installed on one side of the top plate, and the output end of the stepper motor is fixedly connected to the threaded rod.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention utilizes an auxiliary component that drives a second bevel gear via a drive motor. Since the second bevel gear meshes with the first bevel gear, it drives the turntable to rotate. By controlling the rotation angle of the drive motor, the turntable and auxiliary rod rotate. The contact between the auxiliary rod and the connecting shaft causes the inner plate to rotate, allowing for precise angle adjustment and accurate testing of slope conditions. After angle adjustment, the second bevel gear is moved upwards via an electric telescopic rod. Simultaneously, during retraction, the second electric telescopic rod moves the second rotating shaft upwards, causing the rotating shaft to move downwards and contact the rubber ring with the turntable. The rubber ring then limits the turntable's position, effectively fixing the tilt angle of the inner plate and further improving testing accuracy. Furthermore, the included grooves can simulate scenarios with potholes on the road surface, while the first electric telescopic rod can drive the protrusion upwards to simulate obstacles and collisions on the road surface, thus improving test results and providing valuable reference.

A connecting shaft 59 is slidably connected inside the limiting groove 32. The connecting shaft 59 passes through the inner plate 5 and is fixedly connected to it. An auxiliary rod 309 is provided at both ends of the turntable 31. The auxiliary rod 309 contacts the connecting shaft 59. Through the auxiliary component, precise adjustment can be achieved.

[0028] A mounting plate 308 is fixedly connected to one side of side plate 3. An electric telescopic rod 301 is fixedly connected to the bottom of mounting plate 308. A connecting plate 36 is fixedly connected to the output end of electric telescopic rod 301. A bevel gear 34 is rotatably connected to the bottom of connecting plate 36. A drive motor 35 is fixedly connected to the top of connecting plate 36. The output end of drive motor 35 is fixedly connected to bevel gear 34. A bevel gear 33 is fixedly connected to one side of turntable 31. Bevel gear 33 meshes with bevel gear 34. The connection between bevel gear 34 and bevel gear 33... The meshing drives the bevel gear 33 to rotate. A connecting frame 38 is fixedly connected to the bottom of the mounting plate 308. A connecting rod 39 is rotatably connected inside the mounting plate 308. Rotating shaft 302 and rotating shaft 303 are rotatably connected to both ends of the connecting rod 39, respectively. A rubber ring 37 is fixedly connected to one end of the rotating shaft 303. The rotation shaft 302, rotating shaft 303 and connecting rod 39 form a seesaw structure. The rubber ring 37 contacts or separates from the turntable 31 and limits the position of the turntable 31.

[0029] A threaded rod 22 is rotatably connected inside the top plate 2. A slider 23 is threadedly connected to the outside of the threaded rod 22. A traction rope 24 is provided at the bottom of the slider 23. One end of the traction rope 24 is fixedly connected to a traction hook 25. A stepper motor 21 is fixedly installed on one side of the top plate 2. The output end of the stepper motor 21 is fixedly connected to the threaded rod 22. The stepper motor 21 drives the threaded rod 22 to rotate and drives the slider 23 to move, thereby driving the walker to move stably through the traction rope 24 and the traction hook 25. A groove 51 is provided at the top of the inner plate 5. The device has an internal sliding connection with a protrusion 53. It is used to test uneven road sections through a groove 51. An electric telescopic rod 52 is fixedly connected inside the groove 51. The output end of the electric telescopic rod 52 is fixedly connected to the protrusion 53.

The control panel 9 allows the user to operate the device.

[0030] The working principle of this utility model is as follows: The walker is placed on the surface of the inner plate 5, and the traction rope 24 and traction hook 25 are attached to both ends of the walker frame to move the walker steadily. The speed of the stepper motor 21 can be adjusted so that the two stepper motors 21 have different speeds, thus enabling turning tests. Alternatively, the drive motor 35 can drive the bevel gear 34 to rotate. Since the bevel gear 34 meshes with the first bevel gear 33, it can drive the turntable 31 to rotate. By controlling the rotation angle of the drive motor 35, the turntable 31 and the auxiliary rod 309 are driven to rotate. Then, through the contact between the auxiliary rod 309 and the connecting shaft 59, the inner plate 5 rotates, and the angle can be precisely adjusted to adapt to different road conditions. After precise testing and angle adjustment, the electric telescopic rod 301 can drive the bevel gear 34 to move upward. Simultaneously, during the retraction process, the electric telescopic rod 301 drives the rotating shaft 303 to move upward, causing the rotating shaft 302 to move downward and the rubber ring 37 to contact the turntable 31. The rubber ring 37 then limits the turntable 31, achieving the effect of fixing the tilt angle of the inner plate 5, further improving the accuracy of the test. Furthermore, the groove 51 can be used to simulate scenarios with potholes on the road surface. Simultaneously, the electric telescopic rod 52 can drive the protrusion 53 to move upward, simulating scenarios with obstacles and collisions on the road surface, thus improving the test results and providing reference value.
