Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a stroller rollover strength testing machine. Background Technology

[0002] A stroller is a portable seat designed specifically for taking babies out. It provides a safe and comfortable environment, is easy for parents to push, and has functions such as sunshade and wind protection to ensure the safety and comfort of babies during outdoor activities.

[0003] After strollers are manufactured, they undergo a rollover strength test. During this test, the stroller is loaded with a simulated load of a specified weight to mimic the weight of infants at different ages. The stroller is then rolled over at a certain speed and preset angle to test the stability and durability of the overall structure, particularly the connection points and locking mechanisms, to ensure they can withstand sudden external forces without damage or failure. This helps identify potential design and manufacturing defects, ensuring user safety.

[0004] Existing testing machines are typically designed for specific stroller models or structures, and their fixtures, fixing devices, and test parameters cannot be flexibly adjusted. This necessitates replacing specialized parts or even redesigning parts of the structure when testing strollers of different brands or types, which is not only cumbersome and time-consuming but also significantly increases testing costs. Furthermore, frequent replacement of parts can easily lead to a decrease in equipment accuracy, affecting the accuracy and consistency of test results and making it difficult to meet the testing needs of diverse stroller products.

The sliders 6 are slidably connected to the support plate 4 through the sliding grooves 41. The electric push rods 7 are slidably connected to the left and right sides of the top of the support plate 4. The push rods of the electric push rods 7 pass through the sliding grooves 41. Block 6, the electric push rods 7 are all fixedly connected to the slider 6, the push rods of the left and right electric push rods 7 are connected to the clamping plate 8 on the side of the push rods that are close to each other, the first anti-slip pad 81 is connected to the side of the clamping plate 8 that is close to each other, the slider 6 is hinged to the connecting rod 10, the connecting rod 10 is connected to the fixed seat 11, the left and right fixed seats 11 are connected to the first clamping block 13 on the side of the fixed seat 11 that is close to each other, the second clamping block 14 is slidably connected to the fixed seat 11, the third screw 15 is rotatably connected to the fixed seat 11, the third screw 15 is threadedly connected to the second clamping block 14, the hinge connection between the connecting rod 10 and the slider 6 is connected to the first damper 9, the hinge connection between the connecting rod 10 and the fixed seat 11 is connected to the second damper 12, the side of the first clamping block 13 and the second clamping block 14 that is close to each other is connected to the second anti-slip pad 16.

[0021] like Figure 1 As shown, the lifting assembly includes a bracket 101, a guide rod 102, a first screw 103, a first motor 104, and a guide plate 105. The top left and right sides of the base 1 are connected to the bracket 101. The guide rod 102 is connected to one bracket 101, and the first motor 104 is installed at the bottom of the other bracket 101. The output shaft of the first motor 104 is connected to the first screw 103. The first screw 103 is rotatably connected to the other bracket 101. The guide plates 105 are slidably connected to the sides of the left and right brackets 101 that are close to each other. One guide plate 105 is slidably connected to the guide rod 102, and the other guide plate 105 is threadedly connected to the first screw 103. The second motor 3 is installed on the guide plate 105. The first motor 104, the second motor 3, and the electric push rod 7 are all manually or automatically controlled by the external contact screen controller.

[0022] When testing the stroller, the support plate 4 is kept horizontal, and the long rod 107 is not engaged with the slider 6. The touch screen controller of this testing machine drives the first motor 104 to rotate the first screw 103, causing the lifting assembly to move the support plate 4 downward to the lowest position. The stroller is placed on the support plate 4. The second screw 5 is rotated by an electric screwdriver, causing the slider 6 to slide along the slide groove 41. The slider 6 drives the electric push rod 7 to move, aligning the clamping plate 8 with the stroller's wheels. The electric push rod 7 drives the clamping plate 8 to move closer to the wheels, and the stroller is initially fixed under the clamping action of the left and right clamping plates 8. The position of the stroller wheels can be adjusted according to the position of the front and rear clamping plates. The distance between the clamps 8 can be flexibly adjusted to accommodate strollers of different sizes and structures, enhancing the versatility and adaptability of this testing machine. The first anti-slip pad 81 increases the friction between the clamp 8 and the stroller wheels, improving the stability of the clamp 8. Then, rotating the connecting rod 10 brings the fixing seat 11 closer to the stroller frame, positioning the frame between the first clamp 13 and the second clamp 14. Finally, rotating the third screw 15 with an electric screwdriver causes the second clamp 14 to slide closer to the first clamp 13. Thus, the stroller frame is clamped and fixed by the first clamp 13 and the second clamp 14, achieving secondary fixation and preventing the stroller from slipping during testing. The machine can be used for displacement or rotation, and is suitable for stroller frames with different pipe diameters and shapes, improving the fixing effect of the testing machine. The second anti-slip pad 16 can increase the friction between the first clamping block 13 and the second clamping block 14 and the stroller frame, improve the clamping reliability of the first clamping block 13 and the second clamping block 14, and also prevent the first clamping block 13 and the second clamping block 14 from damaging the frame. Then, the long rod 107 is passed through the left and right wheels of the stroller, and then the long rod 107 is fixed to the slider 6 by snap-fit, thereby fixing the stroller three times. Then, the second motor 3 drives the rotating shaft 2 to rotate, causing the support plate 4 to rotate, thereby testing the strength of the stroller. The angle is adjustable, rotating 360 degrees forward and backward or 45 degrees forward and backward. After a single test time is reached, the touch screen controller automatically reverses the above steps to restore the support plate 4 to a horizontal state. When it is necessary to remove the stroller from this testing machine, the second motor 3 drives the rotating shaft 2 to reverse, so that the support plate 4 returns to a horizontal state. Then, the above clamping steps are reversed to release the stroller, and the stroller can be removed from the support plate 4. The first damper 9 can prevent the clamping structure from becoming unstable due to the sudden swing of the connecting rod 10. The second damper 12 can make the clamping block move smoothly and accurately when it is close to the stroller frame, avoiding impact or damage to the stroller due to rapid or unstable movements.
