AI Technical Summary
Traditional car bumper compressive strength testing devices cannot accurately pinpoint areas with weak compressive strength, resulting in poor testing results.
A multi-point detection mechanism is adopted, including several mounting bases, pressure components, pressure switches and indicator lights. Multi-point detection triggers the indicator lights to indicate the pressure position. Combined with an electric push rod and spring support structure, pressure is gradually applied to avoid excessive pressure.
It achieves more accurate detection results, allowing for direct observation of the pressure points on the bumper and avoiding excessive pressure during the detection process from affecting the results.

Detailed Implementation
[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0024] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a vehicle bumper compressive strength testing device.
[0025] Example 1
[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of the automobile bumper compressive strength testing device provided by this utility model includes a base 1, a mounting bracket 2 fixedly installed on the top of the base 1, a pressing mechanism provided inside the top of the mounting bracket 2, and a multi-point testing mechanism provided on the top of the base 1.
[0027] The multi-point detection mechanism includes several mounting bases 9, several pressure components 10, several second springs 13, several pressure switches 15, and several indicator lights 8. The mounting bases 9 are fixedly installed on the top of the base 1. The pressure components 10 are movably connected to the inside of the mounting bases 9 through the second springs 13. The pressure switches 15 are fixedly installed inside the mounting bases 9, with the pressure components 10 located on top of the pressure switches 15. The indicator lights 8 are fixedly installed on one side of the base 1.
[0028] It should be noted that by setting several mounting bases 9 and pressure components 10, a multi-point detection effect can be formed on the top of the base 1, which improves the detection effect. When the pressure component 10 is subjected to pressure, it will trigger the pressure switch 15 to turn on the indicator light 8, so as to more intuitively observe the pressure position of the car bumper.
[0029] In some embodiments, such as Figure 3 As shown, a pressure plate 14 is fixedly installed at the bottom of the pressure component 10, one end of the second spring 13 is in contact with the bottom of the pressure plate 14, and the other end of the second spring 13 is in contact with the inner wall of the mounting base 9. The second spring 13 is located on one side of the pressure switch 15.
[0030] It should be noted that by setting the second spring 13, the bottom of the pressure component 10 can be supported, so that the pressure component 10 does not come into contact with the pressure switch 15 before being subjected to pressure.
[0031] In some embodiments, such as Figure 4As shown, two support seats 6 are fixedly installed on the top of the base 1, and several mounting seats 9 are evenly distributed between the two support seats 6. Support pads 7 are fixedly installed on the top of the support seats 6. A connecting wire 16 is fixedly installed on the connecting end of the pressure switch 15, and the other end of the connecting wire 16 is connected to the indicator light 8.
[0032] It should be noted that the pressure switch 15 can be connected to the indicator light 8 by setting the connecting line 16, so that the pressure switch 15 can control the indicator light 8 to turn on and off. The car bumper can be supported by setting the support seat 6, so that the car bumper can be installed on the support seat 6. The car bumper can be supported by setting the support pad 7.
[0033] Example 2
[0034] In some embodiments, such as Figure 2 As shown, the pressing mechanism includes an electric push rod 3, a pressure plate 4, a pressing member 5, and a first spring 12. The electric push rod 3 is fixedly installed inside the mounting bracket 2, and the pressure plate 4 is fixedly installed at the output end of the electric push rod 3. The bottom of the pressure plate 4 has several movable cavities 11 corresponding to the mounting base 9. The pressing member 5 is movably connected to the inside of the movable cavity 11 through the first spring 12.
[0035] It should be noted that by setting the first spring 12, the pressure holding member 5 can be supported, allowing the pressure holding member 5 to slide inside the movable cavity 11 when subjected to pressure. This allows pressure to be gradually applied to the car bumper during the pressure test, avoiding excessive direct pressure that could affect the test results.
[0036] The electric push rod 3 in this utility model is a known component and will not be described in detail here.
[0037] Working principle: When in use, the car bumper to be tested is installed on the support base 6. Then, the electric push rod 3 drives the pressure plate 4 to move, so that the pressure holding part 5 at the bottom of the pressure plate 4 can contact the top of the car bumper and apply pressure to the top of the car bumper. When a part of the car bumper is deformed by pressure, it will press the pressure part 10 at the bottom downward. The pressure part 10 moves down and contacts the pressure switch 15, thereby triggering the pressure switch 15 and illuminating the indicator light 8 at the corresponding position. This allows for a more intuitive observation of the pressure position of the car bumper.
[0038] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
