Description

Technical Field

[0001] This invention relates to the technical field of automotive component testing, and more particularly to an automotive component testing device and method. Background Technology

[0002] Automotive parts are individual components that make up the various parts and systems of a car, and are typically used to achieve specific functions of the vehicle.

[0003] Automotive components, such as braking and suspension systems, are directly related to vehicle safety. Testing ensures these critical components function properly even under extreme conditions, protecting the safety of drivers and passengers. Shock absorbers absorb road impacts, providing a smooth driving experience. Shock absorbers require shock springs, a crucial component that directly affects driving comfort. To ensure shock springs meet standards, their lifespan needs to be tested. Current automotive component testing equipment, for convenience, simultaneously performs compression tests on multiple shock springs. However, due to the varying diameters of the springs, the limiting effect is insufficient, affecting test data during compression and preventing the springs from being stably supported before lifespan testing.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0040] Example 1, referring to Figures 1-10 The first embodiment of the present invention provides a method for testing automotive parts, which enables testing of springs of different diameters and facilitates the removal and collection of the tested springs.

[0041] First, place the spring on the surface of the placement component 101.

[0042] Then the moving part 203 is driven to compress the right side of the spring by the connecting part 201 and the adjusting part 202.

[0043] The connecting post 201a of the connecting component 201 is plugged into the placement post 101b of the placement component 101.

[0044] Then the drive transmission component 103 changes the angle of multiple rotating plates 101d, which in turn changes the position of multiple adjusting blocks 202a.

[0045] Finally, a compression test is performed on the spring, and the spring after the test is collected by the collection component 102.

[0046] Example 2, refer to Figures 1-10 In the second embodiment of the present invention, a placement component 101, a transmission component 103, and a groove 101b-1 are provided, which can support springs of different diameters.

[0047] The support mechanism 100 includes a placement component 101, a collection component 102, and a transmission component 103. The collection component 102 is disposed at the bottom of the placement component 101, and the transmission component 103 is disposed on the left side of the placement component 101. The placement component 101 includes a first upright plate 101a, a placement column 101b, multiple teeth 101c, multiple rotating plates 101d, multiple rotating teeth 101e, and an annular shell 101f. The left side of the placement column 101b is rotatably connected to the interior of the first upright plate 101a. The multiple teeth 101c are all fixed to the left side of the surface of the placement column 101b and are evenly distributed. The left sides of the multiple rotating plates 101d are respectively fixedly connected to the right sides of the multiple rotating teeth 101e. The left sides of the multiple rotating teeth 101e are all rotatably connected to the interior of the first upright plate 101a, and the right sides of the multiple rotating teeth 101e are all meshed with the surfaces of the multiple teeth 101c. The left side of the annular shell 101f is fixedly connected to the right side of the first upright plate 101a.

[0048] The transmission component 103 includes a mounting bracket 103a, a motor 103b, a transmission belt 103c, and a gear 103d. The right side of the mounting bracket 103a is fixedly connected to the left side of the first upright plate 101a. The right side of the motor 103b is fixedly connected to the left side of the mounting bracket 103a. The right side of the output end of the motor 103b passes through the mounting bracket 103a and is fixedly connected to the left side of the gear 103d. The interior of the transmission belt 103c meshes with the surface of the gear 103d. The left side of the placement column 101b passes through the first upright plate 101a and is fixedly connected to the right side of the gear 103d.

[0049] The interior of the placement column 101b has a groove 101b-1, and the interior of the groove 101b-1 is inserted into the surface of the connecting column 201a.

[0050] Specifically, the number of placement column 101b, multiple teeth 101c, multiple rotating plates 101d, multiple rotating teeth 101e, and annular shell 101f are all multiple and evenly distributed. The multiple rotating plates 101d are at their maximum range at this time. When the placement column 101b rotates counterclockwise, the multiple rotating plates 101d shrink, and conversely, when it rotates clockwise, they expand. The number of gears 103d is multiple and evenly distributed. After the groove 101b-1 is inserted and connected to the connecting column 201a, the rotation of the placement column 101b can carry the connecting column 201a to rotate.

[0051] Furthermore, when it is necessary to test the service life of the spring by compression, the spring is first sleeved on the surface of multiple rotating plates 101d. After multiple springs are installed, two electric telescopic columns 203b are driven, so that the output end of the two electric telescopic columns 203b causes the moving plate 203c to move to the left. The moving plate 203c will bring the connecting column 201a to move to the left, so that the left side of the connecting column 201a is inserted and connected to the inside of the placement column 101b.

[0052] Then, drive motor 103b, causing the output end of motor 103b to drive gear 103d to rotate and drive belt 103c to rotate. Drive belt 103c will cause multiple gears 103d to rotate simultaneously. The rotation of gears 103d will cause placement column 101b to drive multiple teeth 101c to rotate. Multiple teeth 101c will cause multiple rotating teeth 101e to rotate. Multiple rotating teeth 101e will cause multiple rotating plates 101d to rotate. By rotating clockwise through the output end of motor 103b, multiple rotating plates 101d can expand and support the spring from the inside. By rotating counterclockwise, multiple rotating plates 101d will shrink, at which time the spring can be placed.

[0053] Example 3, referring to Figures 1-10This is the third embodiment of the present invention, which provides a collection component 102, a connecting component 201, an adjusting component 202, a moving component 203, an electromagnet 202a-1, a control terminal 203a-1, a first protective plate 101a-1, and a second protective plate 203a-2. Through the collection component 102, the connecting component 201, the adjusting component 202, the moving component 203, the electromagnet 202a-1, the control terminal 203a-1, the first protective plate 101a-1, and the second protective plate 203a-2, compression tests on springs of different diameters can be realized, and the springs after the test can be easily collected.

[0054] The extrusion mechanism 200 includes a connecting component 201, an adjusting component 202, and a moving component 203. The connecting component 201 includes a connecting post 201a, multiple connecting blocks 201b, a fixing block 201c, and multiple protrusions 201d. The sides of the multiple connecting blocks 201b closest to the connecting post 201a are all fixedly connected to the connecting post 201a. The sides of the multiple connecting blocks 201b closest to the fixing block 201c are all fixedly connected to the fixing block 201c. The sides of the multiple protrusions 201d closest to the fixing block 201c are all fixedly connected to the fixing block 201c. The adjusting component 202 is disposed inside the fixing block 201c. The moving component 203 is disposed on the right side of the connecting component 201.

[0055] The collection component 102 includes a base 102a, a collection box 102b, and a rubber pad 102c. The surface of the collection box 102b is inserted and connected to the bottom of the base 102a. The rubber pad 102c is fixed to the bottom inside the collection box 102b. The bottom of the first upright plate 101a is fixedly connected to the left side of the top of the base 102a.

[0056] The adjusting component 202 includes an adjusting block 202a, a slider 202b, two return springs 202c, and a limiting block 202d. The left side of the slider 202b is fixedly connected to the right side of the adjusting block 202a. The surface of the limiting block 202d is slidably connected to the right side of the interior of the adjusting block 202a. The right side of the limiting block 202d is fixedly connected to the left side of the moving plate 203c. The two return springs 202c are respectively sleeved on the left and right sides of the limiting block 202d. The side of each return spring 202c near the limiting block 202d is fixedly connected to the limiting block 202d. The side of each return spring 202c near the slider 202b is fixedly connected to the slider 202b. The surface of the adjusting block 202a is in contact with the surface of the protrusion 201d.

[0057] The movable component 203 includes a second upright plate 203a, two electrically operated telescopic columns 203b, and a movable plate 203c. The bottom of the second upright plate 203a is fixedly connected to the right side of the top of the base 102a. The left sides of the two electrically operated telescopic columns 203b are fixedly connected to the right side of the second upright plate 203a. The left sides of the output ends of the two electrically operated telescopic columns 203b penetrate the second upright plate 203a and are fixedly connected to the right side of the movable plate 203c. The interior of the movable plate 203c is rotatably connected to the right side of the surface of the connecting column 201a.

[0058] An electromagnet 202a-1 is fixedly connected to the left side of the adjusting block 202a, and a control terminal 203a-1 is installed on the right side of the second vertical plate 203a.

[0059] The first protective plate 101a-1 is fixedly connected to the front and rear sides of the right side of the first upright plate 101a, and the second protective plate 203a-2 is fixedly connected to the front and rear sides of the left side of the second upright plate 203a.

[0060] Specifically, the number of connecting parts 201 and adjusting parts 202 are multiple and evenly distributed. The use of rubber pads 102c reduces the impact force generated by the spring falling. The inside of the collection box 102b is used to collect the spring after testing. The number of adjusting blocks 202a, sliders 202b, two reset springs 202c, and limiting blocks 202d are multiple and evenly arranged in a circular array. When the connecting post 201a rotates the fixing block 201c and multiple protrusions 201d through multiple connecting blocks 201b, the multiple protrusions 201d will squeeze the multiple adjusting blocks 202a. Counterclockwise rotation will cause the adjusting blocks 202a to contract, and clockwise rotation will cause the adjusting blocks 202a to contract. The segment 202a will rebound to its original position via two return springs 202c. The output ends of the two electric telescopic columns 203b can move the moving plate 203c. The moving plate 203c can move the connecting part 201 in the left and right directions, thereby compressing the spring to test its service life. The control end 203a-1 can control the use of the electromagnet 202a-1. When energized, it can attract the spring, and when de-energized, it will not attract it. The control end 203a-1 can drive the motor 103b and the electric telescopic column 203b. The first protective plate 101a-1 and the second protective plate 203a-2 both play a protective role to prevent spring debris from flying.

[0061] Furthermore, when the placement column 101b rotates, it causes the connecting column 201a to rotate through the groove 101b-1. The connecting column 201a causes the fixing block 201c to rotate through multiple connecting blocks 201b, which in turn causes multiple protrusions 201d to rotate. When multiple protrusions 201d rotate, the corresponding adjusting block 202a is compressed. The movement of the adjusting block 202a causes the slider 202b to move and the return spring 202c to deform. When the protrusion 201d is rotated clockwise, the adjusting block 202a and the slider 202b will rebound to their original positions through the deformation of the return spring 202c, thus expanding outward. When the protrusion 201d is rotated counterclockwise, it will compress the adjusting block 202a, causing the adjusting block 202a to move inward.

[0062] After the angle is adjusted, the electric telescopic column 203b is driven to move the moving plate 203c to the left. Multiple adjusting blocks 202a will press the right side of the spring to test its service life. After the test is completed, multiple electromagnets 202a-1 are energized through the control terminal 203a-1. The multiple electromagnets 202a-1 will attract the spring. When the spring is removed from the multiple rotating plates 101d, the multiple electromagnets 202a-1 are de-energized, and the spring will fall into the collection box 102b. During the test, the first protective plate 101a-1 and the second protective plate 203a-2 play a protective role. The outer side of the first protective plate 101a-1 will slide and connect with the inner side of the second protective plate 203a-2.

[0063] The remaining structure is the same as that in Example 2.

[0064] Example 4, refer to Figures 1-10 This is the fourth embodiment of the present invention, which differs from the third embodiment in that it provides an automotive parts testing device.

[0065] When it is necessary to test the service life of the spring by compression, the spring is first placed on the surface of multiple rotating plates 101d. After multiple springs are installed, two electric telescopic columns 203b are driven so that the output ends of the two electric telescopic columns 203b move the moving plate 203c to the left. The moving plate 203c will bring the connecting column 201a to move to the left, so that the left side of the connecting column 201a is inserted into the interior of the placement column 101b.

[0066] Then, drive motor 103b, causing the output end of motor 103b to drive gear 103d to rotate and drive belt 103c to rotate. Drive belt 103c will cause multiple gears 103d to rotate simultaneously. The rotation of gears 103d will cause placement column 101b to drive multiple teeth 101c to rotate. Multiple teeth 101c will cause multiple rotating teeth 101e to rotate. Multiple rotating teeth 101e will cause multiple rotating plates 101d to rotate. By rotating clockwise through the output end of motor 103b, multiple rotating plates 101d can expand and support the spring from the inside. By rotating counterclockwise, multiple rotating plates 101d will shrink, at which time the spring can be placed.

[0067] When the placement post 101b rotates, it causes the connecting post 201a to rotate through the groove 101b-1. The connecting post 201a causes the fixing block 201c to rotate through multiple connecting blocks 201b, which in turn causes multiple protrusions 201d to rotate. When multiple protrusions 201d rotate, the corresponding adjusting block 202a is squeezed. The movement of the adjusting block 202a causes the slider 202b to move and the return spring 202c to deform. When the protrusion 201d is rotated clockwise, the adjusting block 202a and the slider 202b will rebound to their original positions through the deformation of the return spring 202c, thus expanding outward. When the protrusion 201d is rotated counterclockwise, it will squeeze the adjusting block 202a, causing the adjusting block 202a to move inward.

[0068] After the angle is adjusted, the electric telescopic column 203b is driven to move the moving plate 203c to the left. Multiple adjusting blocks 202a will press the right side of the spring to test its service life. After the test is completed, multiple electromagnets 202a-1 are energized through the control terminal 203a-1. The multiple electromagnets 202a-1 will attract the spring. When the spring is removed from the multiple rotating plates 101d, the multiple electromagnets 202a-1 are de-energized, and the spring will fall into the collection box 102b. During the test, the first protective plate 101a-1 and the second protective plate 203a-2 play a protective role. The outer side of the first protective plate 101a-1 will slide and connect with the inner side of the second protective plate 203a-2.

[0069] In summary, by supporting identical springs with placement component 101, for springs of different diameters, the angles of multiple rotating plates 101d can be adjusted by driving the transmission component 103, which can quickly and stably support the springs, making the rotating plates 101d contact the inner side of the springs. The adjustment component 202 changes with the rotation of the rotating plates 101d. By driving the moving component 203 to simultaneously compress multiple springs, a benchmark dataset can be obtained for analyzing the springs' compressive strength, fatigue life, and other indicators.
