Embodiment 1

[0032] Embodiment 1, as shown in Figure 1 and Figure 2, the acceleration simulation table includes: a bracket 100, a cylinder 13, a cylinder seat 14, a rack and cylinder connection block 1, a rack 2, a rolling guide rail 3, a spacer 11, and a bearing seat 5 , Gear shaft 4, crank 6, connecting rod 7, slider 9, special pin 8, aluminum plate 10 and linear bearing 12. As shown in Figure 3, the cylinder 13 and the cylinder seat 14 are fixed together on the bracket 100, the cylinder 13 is connected with the rack 2 through the rack cylinder connecting block 1, and drives the rack 2 to slide on the rolling guide rail 3, and the rack 2 passes through the pad The block 11 is in rigid contact with the rolling guide rail 3, the rack 2 meshes with the gear shaft 4, the rack 2 is located directly below the gear shaft 4, and drives the gear shaft 4 to rotate, and the gear shaft is supported by two bearing seats 5 fixed on the bracket , the crank 6 here adopts a disk, which is fixed on one en...

Embodiment 2

[0044] In the second embodiment, compared with the acceleration simulation platform in the first embodiment, a buffer mechanism is added, as shown in Figure 6, the buffer mechanism includes: a linear bearing 31, a guide rod 32, a spring 33, a housing 34 and a piston 35, and 31 sets of linear bearings On the guide rod 32 and connected with one end of the spring 33, the other end of the spring 34 is connected with the piston 35, the piston 35 slides inside the casing 34, the casing 34 is connected with the linear bearing 31, and fixed on the bracket 100 through the rolling guide rail 3 . The main effect of adding the buffer mechanism is to make the module under test stop quickly after reaching the target acceleration, effectively reducing the time required for testing.

Embodiment 3

[0045] The difference between the third embodiment and the acceleration simulation platform in the second embodiment is that the buffer mechanism includes: a support base 41, a spring 43, a rubber rod 44 and a rubber column 42, and the support base 41 is fixed on the bracket 100 through the rolling guide rail 3 , The rubber post 42 is connected to one end of the spring 43 , the other end of the spring 43 is connected to the rubber rod 44 , and the rubber rod 44 slides in the cavity of the rubber post 42 . The main effect of the buffer mechanism is to make the module under test stop quickly after reaching the target acceleration, effectively reducing the time required for testing.

The cylinder drives measured module move in variable motion by mechanical transmission device. The mechanical transmission and measured module are set on the support. The invention is provided with simple operation and low cost so on. It can solve high cost of prior related equipment and complex operation so on well.

Description

【Technical field】 [0001] The invention relates to an acceleration simulation platform, in particular to an acceleration simulation platform used for collision performance detection and the like of an electronic control unit of an automobile safety air bag. 【Background technique】 [0002] With the wide application of airbags in automobiles, it is becoming more and more important to test the product performance of its electronic control unit. The electronic control unit of the airbag needs to test its performance before leaving the factory, and check whether the electronic control unit can send a control signal when the car collides, and control the airbag to open in time to protect the driver. Acceleration is simulated. This test can also be applied to other products. For example, some electronic products need to be tested for their ability to withstand acceleration to determine whether they can meet the work requirements; requirements, so the demand for acceleration simula...
