[0014] See also Figure 1 to Figure 7In an embodiment of the present invention, an automobile bumper automatic testing device includes a slide 1, a tractor 2, a slide 3, a traction disengagement mechanism 4, an impact barrier 5 and an impact bar 6, wherein the slide 1 is trapezoidal, a limited sliding groove is provided on the slide 1, the tractor 2 is slidably arranged along the limited sliding groove, the slide 3 is slidably arranged on the slide 1, and a traction disengagement mechanism 4 is arranged between the tractor 2 and the slide 3, the impact barrier 5 is fixedly arranged on one side of the slide 1, at least one impact bar 6 is slidably arranged in the impact barrier 5, and a protective cover 7 is fixedly arranged on the outer side of the impact barrier 5; The traction disengagement mechanism 4 comprises a fixed seat 41, a deflection plate 42, a clamping plate 43 and a reset mechanism 44, wherein the fixed seat 41 is fixedly arranged on the tractor 2, a plurality of deflection plates 42 are rotatably arranged on the fixed seat 41, a clamping plate 43 for clamping the deflection plate 42 is symmetrically slidably arranged at the bottom of the fixed seat 41, and a reset mechanism 44 for resetting the deflection plate 42 is also slidably arranged in the fixed seat 41; Two clamping rods 31 for fixing the car bumper are fixedly provided at the front end of the slide 3, a drag plate 32 is fixedly provided on the slide 3, a plurality of placement grooves 33 for placing counterweight blocks are opened on the drag plate 32, and a plurality of fixing plates 34 are also fixedly provided at the bottom of the slide 3, the number of the fixing plates 34 is the same as the number of the deflection plates 42, and the fixing plates 34 can clamp the deflection plates 42.

[0015] During implementation, the car bumper is fixed on the slide 3 by two clamping rods 31, and then a corresponding number of counterweight blocks are placed in the placement groove 33 according to the car counterweight, and the counterweight blocks are tightened and fixed by bolts, and then the slide 3 is driven by the tractor 2 to slide, so that the car bumper hits the impact bar 6, and various data during the collision are recorded and the deformation of the bumper is observed. The number of impact bars 6 can be increased or decreased according to the detection requirements, thereby simulating a variety of different impact conditions, so that the test results are more accurate. In the test process, the tractor 2 can be separated from the slide 3 before the collision occurs under the action of the traction separation mechanism 4, so that the force generated by the collision after the collision does not act on the tractor 2, thereby avoiding damage to the tractor 2 and reducing the maintenance cost.

[0016] In this embodiment, Figure 2 and Figure 3A plurality of arc grooves 411 are provided at the bottom of the fixing seat 41, and a clamping rod 421 is symmetrically fixedly arranged on the deflection plate 42, and the clamping rod 421 penetrates the arc groove 411 and slides along the arc groove 411, and the clamping plate 43 is located on one side of the arc groove 411, and the clamping plate 43 can be clamped above the clamping rod 421, and a hydraulic telescopic rod 412 for driving the clamping plate 43 to slide is also fixedly arranged on the fixing seat 41.

[0017] During implementation, initially, the tractor 2 and the carriage 3 are located on one side of the carriage 1, and the impact barrier 5 is located on the other side of the carriage 1. At this time, the deflection plate 42 is in a vertical state, and the clamping plate 43 is clamped on the clamping rod 421, that is, at this time, the deflection plate 42 is restricted by the clamping plate 43 and will not deflect, so that the deflection plate 42 and the fixed plate 34 are clamped together. When the tractor 2 moves, the carriage 3 can be effectively driven to slide through the traction disengagement mechanism 4. Then, when the bumper is about to hit the impact bar 6, the hydraulic telescopic rod 412 drives the clamping plate 43 to slide, so that the clamping plate 43 The deflection plate 42 is disengaged from the clamping rod 421. At this time, the deflection plate 42 is not restricted, that is, the deflection plate 42 is deflected when subjected to force. When a collision occurs, the carriage 3 stops moving, so that the fixed plate 34 stops being subjected to force. At this time, the deflection plate 42 is deflected and then disengaged from the fixed plate 34, that is, the impact force will not be transmitted to the tractor 2, effectively avoiding damage to the tractor 2 and reducing maintenance costs. After an impact test is completed, the tractor 2 and the carriage 3 are reset, and the deflection plate 42 is reset by the reset mechanism 44, and the deflection plate 42 is re-restricted by the clamping plate 43, so that the deflection plate 42 and the fixed plate 34 are re-locked together.

[0018] In this embodiment, Figure 2 and Figure 3 The reset mechanism 44 includes a sliding rod 441, a reset bar 442 and a pull rod 443, wherein the sliding rod 441 is configured with two, and the two sliding rods 441 are symmetrically slidably arranged in the fixed seat 41, a spring is arranged between the sliding rod 441 and the fixed seat 41, a plurality of reset bars 442 are fixedly arranged on the sliding rod 441, and one end of the two sliding rods 441 is fixedly connected by a pull rod 443.

[0019] In this embodiment, Figure 2 and Figure 3 The fixing seat 41 is provided with a plurality of arc grooves 413, and the deflection plate 42 is symmetrically fixed with a reset rod 422, the reset rod 422 penetrates the arc groove 413 and slides along the arc groove 413, the reset bar 442 is located on one side of the arc groove 413, and the reset bar 442 can push the reset rod 422 to slide along the arc groove 413.

[0020] During implementation, when the deflection plate 42 deflects due to impact, the reset rod 422 will slide along the second arc groove 413, that is, the reset rod 422 will move radially. At this time, the pull rod 443 is pulled, so that the multiple reset bars 442 can push the multiple reset rods 422 to slide. At this time, the reset rod 422 slides along the second arc groove 413 under the thrust of the reset bar 442 and the restriction of the second arc groove 413, and the clamping rod 421 also slides along the first arc groove 411. When the deflection plate 42 is deflected to a vertical state, the clamping rod 421 is at the lowest end of the arc groove 411, and then the hydraulic telescopic rod 412 is used to drive the clamping plate 43 to slide and clamp above the clamping rod 421, thereby restricting the clamping rod 421 so that the clamping rod 421 does not slide along the arc groove 411, that is, the deflection plate 42 is restricted and does not deflect, thereby achieving the effect of collision separation of the tractor 2 while ensuring the sliding of the driving slide 3, thereby ensuring that the tractor 2 is not damaged.

[0021] In this embodiment, Figure 6 and Figure 7 The impact barrier 5 is fixedly provided with a support bar 51, in which a T-shaped slot 511 is provided, and the impact bar 6 is fixedly provided with a T-shaped block 61, and the T-shaped block 61 slides along the T-shaped slot 511; Two clamping plates 512 are slidably provided in the support bar 51, and two lead screws are rotatably provided on the support bar 51. The two lead screws respectively drive the two clamping plates 512 to slide, and the two clamping plates 512 can push the T-block 61 to slide along the T-slot 511 and clamp it.

[0022] In particular, providing the two clamping plates 512 can ensure that no matter how the number and position of the impact bars 6 in the support bar 51 change, the impact bars 6 can be firmly connected to the impact barrier 5, thereby ensuring that the impact bars 6 will not shift when a collision occurs, thereby improving its safety.

[0023] In summary, when the present invention is implemented, the traction disengagement mechanism 4 is provided so that the tractor 2 and the slide 3 can be separated before the collision occurs, so that the impact force generated by the collision will not act on the tractor 2, effectively avoiding damage to the tractor 2 and further reducing maintenance costs. A reset mechanism 44 is provided in the traction disengagement mechanism 4, so that the multiple deflection plates 42 can be quickly reset after deflection and disengagement, and re-engaged with the fixed plate 34, thereby improving the convenience of testing and effectively improving the test efficiency. In addition, an impact bar 6 is slidably provided on the impact barrier 5, and impact tests under various different conditions are simulated by increasing or decreasing the number of the impact bars 6 and moving the position of the impact bars 6, thereby further making the test results more comprehensive and accurate.
