[0002] As an important safety device of an automobile, the automobile bumper has multiple functions such as safety protection, vehicle decoration, and improvement of the aerodynamic characteristics of the vehicle. After the automobile bumper is formed, it needs to go through a series of processing and testing to ensure its quality and performance.

[0003] Currently, traditional automobile bumper collision tests mainly rely on manual operation and simple mechanical equipment. During the test, only a single collision test can be carried out, resulting in low test efficiency. In the traditional test process, the automobile bumper is often installed on a power vehicle, and the bumper is towed by the power vehicle to impact a barrier for testing. When the bumper collides, the impact force often exceeds the transmission to the power vehicle and the fixing frame, resulting in damage to the fixing frame and the power vehicle. As a result, a large amount of test materials and equipment maintenance are required, leading to high test costs. Moreover, due to the low test efficiency, the overall cost of automobile production is also increased.

[0023] Please refer to Figures 1 to 7, in an embodiment of the present invention, an automated testing device for an automotive bumper includes a sliding seat 1, a towing vehicle 2, a sliding frame 3, a towing detachment mechanism 4, an impact barrier 5, and an impact strip 6. Among them, the sliding seat 1 is trapezoidal, a limiting sliding groove is provided on the sliding seat 1, the towing vehicle 2 is slidably arranged along the limiting sliding groove, the sliding frame 3 is slidably arranged on the sliding seat 1, and a towing detachment mechanism 4 is arranged between the towing vehicle 2 and the sliding frame 3. The impact barrier 5 is fixedly arranged on one side of the sliding seat 1, at least one impact strip 6 is slidably arranged in the impact barrier 5, and a protective cover 7 is fixedly arranged outside the impact barrier 5;

[0024] The towing detachment mechanism 4 includes a fixed seat 41, a deflecting plate 42, a clamping plate 43, and a reset mechanism 44. Among them, the fixed seat 41 is fixedly arranged on the towing vehicle 2, a plurality of deflecting plates 42 are rotatably arranged on the fixed seat 41, clamping plates 43 for clamping the deflecting plates 42 are symmetrically slidably arranged at the bottom of the fixed seat 41, and a reset mechanism 44 for resetting the deflecting plates 42 is also slidably arranged in the fixed seat 41;

[0025] Two clamping rods 31 for fixing the automotive bumper are fixedly arranged at the front end of the sliding frame 3. A drag plate 32 is fixedly arranged on the sliding frame 3, a plurality of placement grooves 33 for placing counterweight blocks are provided on the drag plate 32, and a plurality of fixing plates 34 are also fixedly arranged at the bottom of the sliding frame 3. The number of the fixing plates 34 is the same as that of the deflecting plates 42, and the fixing plates 34 can clamp the deflecting plates 42.

[0026] During implementation, the automotive bumper is fixedly arranged on the sliding frame 3 through the two clamping rods 31. Subsequently, corresponding numbers of counterweight blocks are placed in the placement grooves 33 according to the vehicle weight, and the counterweight blocks are tightened and fixed with bolts. Then, the towing vehicle 2 is used to drive the sliding frame 3 to slide, so that the automotive bumper impacts on the impact strip 6. Various data during the collision process are recorded and the deformation condition of the bumper is observed. The number of impact strips 6 can be increased or decreased according to the detection requirements, thereby simulating a variety of different impact situations, making the test results more accurate. And during the test process, the towing vehicle 2 can be detached from the sliding frame 3 under the action of the towing detachment mechanism 4 before the impact occurs, so that the force generated by the impact after the impact does not act on the towing vehicle 2, avoiding damage to the towing vehicle 2 and thus reducing the maintenance cost.

[0027] In this embodiment, as 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] During implementation, when the impact occurs and the deflector plate 42 deflects, at this time the reset rod 422 will slide along the second arc-shaped groove 413, that is, the reset rod 422 will generate a radial movement. At this time, the pull rod 443 is pulled, so that a plurality of the reset strips 442 can push a plurality of the reset rods 422 to slide. At this time, the reset rod 422 slides along the second arc-shaped groove 413 under the thrust of the reset strip 442 and the restriction of the second arc-shaped groove 413. At the same time, the latch rod 421 also slides along the first arc-shaped groove 411. When the deflector plate 42 deflects to the vertical state, at this time the latch rod 421 is at the lowest end of the first arc-shaped groove 411. Subsequently, the hydraulic telescopic rod 412 is used to drive the clamping plate 43 to slide and clamp above the latch rod 421, thereby restricting the latch rod 421 so that the latch rod 421 will not slide along the first arc-shaped groove 411, that is, the deflector plate 42 is restricted and will not deflect, thereby realizing the effect that the tractor 2 can achieve impact separation while ensuring the sliding of the driving carriage 3, and further ensuring that the tractor 2 is not damaged.

[0032] In this embodiment, as Figure 6 and Figure 7 , a support strip 51 is fixedly arranged on the impact barrier 5, a T-shaped groove 511 is formed in the support strip 51, a T-shaped block 61 is fixedly arranged on the impact strip 6, and the T-shaped block 61 slides along the T-shaped groove 511;

[0033] Two clamping plates 512 are slidably arranged in the support strip 51, two lead screws are rotatably arranged on the support strip 51, the two lead screws respectively drive the two clamping plates 512 to slide, and the two clamping plates 512 can push the T-shaped block 61 to slide along the T-shaped groove 511 and clamp it.

[0034] Particularly, setting the two clamping plates 512 can ensure that no matter how the number and position of the impact strips 6 in the support strip 51 change, the impact strips 6 can be firmly connected to the impact barrier 5, thereby ensuring that the impact strips 6 will not shift during impact and improving its safety.

[0035] In summary, during the implementation of the present invention, through the setting of the traction detachment mechanism 4, the tractor 2 and the carriage 3 can be detached before the impact occurs, so that the impact force generated by the impact will not act on the tractor 2, effectively avoiding the damage of the tractor 2, further reducing the maintenance cost, and a reset mechanism 44 is arranged in the traction detachment mechanism 4, so that a plurality of deflector plates 42 can be quickly reset after deflecting and detaching, and can be re-latched with the fixed plate 34, thereby improving the convenience of the test and effectively improving the test efficiency. In addition, the impact strip 6 is slidably arranged on the impact barrier 5, and by increasing or decreasing the number of the impact strips 6 and moving the position of the impact strip 6, impact tests under various different conditions can be simulated, further making the test results more comprehensive and accurate.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
