Description

technical field [0001] The invention relates to a car seat testing machine, in particular to a car seat bump and creep durability test machine, which belongs to a kind of testing equipment and is used for the durability test of car seat bump and creep. Background technique [0002] The standard for the bump and creep test of the car seat is: at a frequency of 100 times / min, the seat cushion is subjected to a vibration test of 100,000 times. and pads are undamaged. [0003] The requirements of the car seat bump and creep test are: fix the test sample on the platform of the testing machine, adjust the sample so that the center line of the H point of the sample is aligned with the simulated false buttocks, and adjust the height of the simulated false buttocks. When the seat is loaded with a load of 68kg, the bump amplitude is 30mm from peak to peak, and the creep angle is 21°. [0004] In the prior art, the crankshaft mechanism is used to convert the circular motion into the ...

Problems solved by technology

If only one seat such as the driver's seat or co-pilot's seat is used for the test, and other power sources cannot be turned off during the test, it will appear that there is only one test seat, and the three positions of the test machine are all in the same position. Start, a great waste of energy (because of the large power of the equipped motor), also increases the loss of the machine

[0007] 2. After the jolting motor outputs kinetic energy, three seats are driven, so the lack of kinetic energy during the test is considered in the design, and an energy stabilization device needs to be added, which means adding an inertia wheel to stabilize the vibration stability , complex structure and high cost

[0008] 3. Considering the three-person seat, the H points of the three seats cannot be aligned with the center of gravity of the peristaltic buttocks of the test equipment at the same time, so two sets of horizontal movement mechanisms in the X and Y directions can only be added to the equipment to ensure that the structure is complicated. high cost

[0009] 4. In the turbulence test, the peristaltic power mechanism is fixed on the support. In order to ensure the stability of the support, it is designed as a turbulence guide column sleeve, slider, slide rail, etc. to meet the up and down movement. During the long-term operation, it is easy to causing this component to get stuck

[0010] 5. The creep test is to design the motor in a horizontal state, and the motor drives a pair of bevel gears to convert horizontal rotation into vertical rotation; the disadvantages are: relying on the rotation of a pair of bevel gears, the production cost is high, and it is easy to wear and the noise is low. larger

[0011] 6. All moving parts need to be lubricated manually, which increases the workload of the tester and cannot guarantee the accuracy of the amount of lubricating oil injected

[0012] 7. There is no bumping platform, and the seat fixing plate is directly used as a bumping platform, which is inconvenient to install during use
