Description
Technical Field
[0001] This invention relates to the field of vehicle component performance testing technology, and in particular to a performance testing device for aluminum materials used in vehicle protection. Background Technology
[0002] Because aluminum alloys are lightweight, do not rust, and have good energy absorption and heat dissipation properties, they are widely used in automotive structures. In addition to the aluminum alloy body-in-white, aluminum alloy doors, hoods, and fenders of high-end cars, aluminum alloys are also widely used in automotive chassis.
[0003] The engine is located at the bottom of a car. To protect the engine during driving, an aluminum alloy underbody shield is installed at the bottom of the engine, which does not affect heat dissipation. The presence of the underbody shield significantly improves vehicle safety. Currently, the testing of automotive aluminum materials mainly focuses on the compressive strength testing of traditional beams and body panels. However, the underbody shield is unlikely to be subjected to frontal impacts during normal driving. It is mainly affected by friction caused by ground protrusions and tilting pressure caused by friction, or the impact of high-speed stones kicked up by the vehicle. These factors are the main causes affecting the underbody shield. Therefore, the testing of the underbody shield should be designed specifically for its working environment. However, existing equipment for testing the performance of aluminum materials cannot effectively achieve the above testing results. Therefore, a vehicle protection aluminum material performance testing device specifically for engine underbody shields is proposed. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that in the prior art, the possibility of the engine underbody protection plate being subjected to frontal impact force during normal driving is zero. It is mainly affected by friction caused by ground protrusions and tilting pressure caused by friction, or the impact of high-speed stones splashed up during vehicle driving. Therefore, this invention proposes a vehicle protection aluminum material performance testing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A performance testing device for aluminum materials used in vehicle protection includes an automatic circulation device and a testing device disposed within a protective chamber.

Each component is fixedly connected to a power storage plate, which is connected to a sliding connecting rod via an elastic power storage component. Two sliding connecting rods are connected to a reciprocating plate. A raised abrasive grinding layer is fixedly connected above the reciprocating plate. Beating components are connected to the two side walls of the reciprocating plate via elastic rubber ropes. A conveyor motor is installed on the support base. The output end of the conveyor motor is connected to a transmission belt via a belt drive component. A rectangular opening is provided on the support base through the side wall. A traction plate is provided on the transmission belt through the rectangular opening. A carrying plate adapted to the traction plate is fixedly connected to the bottom of the reciprocating plate.
[0007] Preferably, the drive ring is rotatably mounted on the inner side wall of the protective chamber, and the outer side wall of the drive ring is evenly provided with ring tooth grooves that mesh with the drive gear. The side wall of the conveyor disc is fixedly connected to the drive ring.
[0008] Preferably, the limiting component includes L-shaped side strips disposed opposite each other on the surface of the conveyor tray, and a bottom blocking strip is provided at one end of each of the two L-shaped side strips.
[0009] Preferably, the protective chamber is provided with a protective top plate connected by hinges, and a storage box is provided at the bottom of the protective top plate. The storage box has an inlet at the top that penetrates the protective top plate and an outlet at the bottom. A blocking ring located at the bottom of the storage box is fixedly connected to the outer wall of the drive ring. The blocking ring has a notch that matches the multi-faceted position display screen of the conveyor plate.
[0010] Preferably, the adjustable contact element includes a telescopic hole through the side wall of the conveyor plate, an elastic column is provided in the telescopic hole, and a rubber disc with an aluminum back contact is provided at the end of the elastic column.
[0011] The other end of the elastic column is fixedly connected to an abutment plate. The abutment plate is connected to the inner wall of the conveying plate through an abutment spring sleeved on the elastic column. An abutment ball is provided on the side wall of the abutment plate, and an arc-shaped abutment ring is provided on the outer side wall of the inner cylinder.
[0012] Preferably, one end of the elastic rubber rope is connected to the side wall of the reciprocating plate, and the other end is connected to the striking component. The support base is provided with a limiting groove for engaging the striking component. The limiting groove consists of a semi-circular groove and a rectangular limiting groove.

This allows for testing the performance of the engine underbody protection plate during actual driving and obtaining accurate data on different aluminum components.
[0017] 2. This invention is specifically designed to address the impact of gravel splashing onto the engine underbody protection plate during vehicle operation.

[0018] 3. This solution involves setting up a protective chamber to conduct automatic reciprocating cyclic performance testing of the aluminum material of the engine underbody protection plate. The entire impact test is fully automated, improving testing efficiency while ensuring the safety of the testing and observation personnel. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0028] Example 1
[0029] Reference Figure 1-7 A performance testing device for aluminum materials used in vehicle protection includes an automatic circulation device and a testing device installed in a protective chamber 1. By setting up the protective chamber 1, it can be ensured that the test is conducted in an environment isolated from the outside, thereby ensuring safety during the testing process.
[0030] The automatic circulation device includes a circulation motor 2 installed on the side wall of the protective chamber 1. The circulation motor 2 is intermittently driven, and the transmission interval is sufficient to meet the time required for the detection process of the detection device. The circulation motor 2 is connected to a drive ring 4 via a drive gear 3. An inner cylinder 6 is fixedly connected to the side wall of the protective chamber 1. A function display panel 5 is provided at the end of the inner cylinder 6. The function display panel 5 is a display panel for the status and control time of various components on the detection equipment. This is a conventional technology and will not be described in detail here. A conveyor plate 7 with multiple facets is sleeved and connected on the inner cylinder 6. Multiple limit components are evenly arranged on the conveyor plate 7.
[0031] Furthermore, the drive ring 4 is rotatably mounted on the inner wall of the protective chamber 1. The outer wall of the drive ring 4 is evenly provided with ring tooth grooves that mesh with the drive gear 3. The side wall of the conveyor plate 7 is fixedly connected to the drive ring 4. The multifaceted surface of the conveyor plate 7 is provided with L-shaped side strips 20 arranged opposite to each other. One end of each L-shaped side strip 20 is provided with a bottom blocking strip 21.
[0032] It should be noted that the drive ring 4 is sleeved on the outer wall of the inner cylinder 6, and the inner cylinder 6 and the drive ring 4 are rotatably connected. The function of the drive ring 4 is to drive the conveyor plate 7 and the blocking ring 25 on it to rotate effectively.
[0033] In this scheme, the conveyor plate 7 is hexagonal, and its shape can be flexibly adjusted according to the number of control test groups required during the experimental testing process.
[0034] Furthermore, the top of the protective chamber 1 is provided with a protective top plate 22 connected by hinges, and the bottom of the protective top plate 22 is provided with an inclined storage box 23. The top of the storage box 23 has an inlet 24 that penetrates the protective top plate 22, and the bottom of the storage box 23 has an outlet. The outer wall of the drive ring 4 is fixedly connected with a blocking ring 25 located at the bottom of the storage box 23. The blocking ring 25 has a notch 26 that matches the multi-faceted position display screen of the conveyor plate 7.
[0035] The advantage of this further approach is that a blocking ring 25, which rotates together with the conveyor plate 7, is provided between the bottom of the storage box 23 and the conveyor plate 7. By using the blocking ring 25, the engine under guard plate inside the storage box 23 is limited when it enters the limiting component on the conveyor plate 7. This ensures that the discharge port at the bottom of the storage box 23 will only be opened at the matching notch 26. At other times, the discharge port will be blocked by the side wall of the blocking ring 25, preventing it from falling off and affecting the normal rotation of the conveyor plate 7.
[0036] An adjustable abutment is provided on the conveyor plate 7 located in the limiting assembly. Further, the adjustable abutment includes a telescopic hole that penetrates the side wall of the conveyor plate 7, an elastic post 27 is provided in the telescopic hole, and a rubber plate 28 with aluminum back abutment is provided at the end of the elastic post 27.
[0037] Under pressure, the rubber disc 28 will squeeze the back of the engine under guard plate within the limiting assembly, thereby preventing the engine under guard plate within the limiting assembly from moving and falling off as the conveyor disc 7 rotates, thus ensuring the inspection process can proceed.
[0038] Furthermore, the other end of the elastic column 27 is fixedly connected to an abutment plate 29. The abutment plate 29 is connected to the inner wall of the conveyor plate 7 through an abutment spring sleeved on the elastic column 27. An abutment ball is provided on the side wall of the abutment plate 29, and an arc-shaped abutment ring 30 is provided on the outer side wall of the inner cylinder 6. The abutment ring 30 is concave at the top position and convex at the rest. This means that the engine lower guard plate can only be released and removed when the abutment plate 29 is concave. At other positions, the engine lower guard plate is in a limited state.
[0039] The further advantage of this approach is that the engine underguard plate, which is normally installed on the vehicle, is installed using elastic bolts to ensure that the engine underguard plate has a certain buffering effect. Therefore, in order to ensure the accuracy of the experiment, the elastic column 27 under the action of the contact spring will provide a certain buffering effect on the engine underguard plate, thereby more realistically simulating the actual situation.
[0040] The detection device includes a support base 8, with a power storage plate 9 fixedly connected to both sides of the support base 8. The power storage plate 9 is connected to a sliding connecting rod 10 through an elastic power storage component. The two sliding connecting rods 10 are connected to a reciprocating plate 11. Further, the elastic power storage component includes a rectangular groove opened on the side wall of the power storage plate 9. A sliding guide post 33 is fixedly connected to the inner wall of the rectangular groove. A power storage block 34 is slidably arranged on the sliding guide post 33. The power storage block 34 is connected to the sliding connecting rod 10 and is connected to the inner wall of the rectangular groove through an anti-spring sleeved on the sliding guide post 33.
[0041] A raised abrasive grinding layer 12 is fixedly connected above the reciprocating plate 11. The abrasive grinding layer 12 can be made of crushed stone to simulate the friction environment of the ground as much as possible to ensure the accuracy of the experimental data. Similarly, the striking part 14 below is also made of a material with a hardness similar to that of stone.
[0042] The two side walls of the reciprocating plate 11 are connected to the striking parts 14 by elastic rubber ropes 13. Furthermore, one end of the elastic rubber rope 13 is connected to the side wall of the reciprocating plate 11, and the other end is connected to the striking parts 14. The support base 8 is provided with a limiting groove 31 for engaging the striking parts 14. The limiting groove 31 is composed of a semi-circular groove and a rectangular limiting groove. The end of the rectangular limiting groove is connected to a limiting telescopic block 32 by a pressure spring.
[0043] When the striking element 14 connected to the elastic rubber rope 13 is in the semi-circular groove, it will fall into the limiting groove 31. At this time, when the reciprocating plate 11 is driven forward by the traction plate 18, the striking element 14 will move to the limiting telescopic block 32. The continuous movement of the reciprocating plate 11 will cause the elastic rubber rope 13 to be stretched. When the stretching force is greater than the resistance of the limiting telescopic block 32, the striking element 14 will quickly impact the engine lower guard plate, thereby simulating the real situation of gravel hitting the engine lower guard plate.
[0044] A conveyor motor 15 is installed on the support base 8. The output end of the conveyor motor 15 is connected to a transmission belt 16 via a belt drive component. A rectangular opening 17 is provided on the support base 8 through the side wall. A traction plate 18 is provided on the transmission belt 16 through the rectangular opening 17. A carrying plate 19 adapted to the traction plate 18 is fixedly connected to the bottom of the reciprocating plate 11. The belt drive component includes two rotating shafts 35 rotatably installed at both ends of the support base 8. A pulley is fixed at the end of the rotating shaft 35. The rotating shaft 35 located on one side is connected to the output end of the conveyor motor 15. The two ends of the transmission belt 16 are engaged with the pulley.
[0045] When inspecting the engine underbody, the present invention places the engine underbody to be inspected into the storage box 23, turns on the circulation motor 2 and the conveying motor 15. When the circulation motor 2 rotates, it drives the drive gear 3 and drive ring 4 connected to it to rotate the conveying plate 7. When the limiting component set on the conveying plate 7 moves to the predetermined position, the matching notch 26 on the blocking ring 25 aligns with the discharge port of the storage box 23. Under the action of gravity, the engine underbody located in the storage box 23 will move downward into the limiting component composed of the L-shaped side strip 20 and the bottom blocking strip 21, and be continuously conveyed to the inspection device below. During the conveying process, the pressing of the pressing plate 29 by the pressing ring 30 will achieve the pressing and fastening of the engine underbody by the rubber plate 28.
[0046] When the engine under guard plate to be tested is transported to the bottom, it will be driven by the traction block driven by the conveyor motor 15 to drive the reciprocating plate 11 to move continuously by accumulating force. During the process of accumulating force, when the traction plate 18 set on the transmission belt 16 rotates to the pulley to turn, the traction force on the carrying plate 19 will be released. Under the action of the anti-spring, the abrasive grinding layer 12 set on the reciprocating plate 11 will repeatedly impact and grind the engine under guard plate. In addition, during the process of accumulating force, the reciprocating plate 11 will continuously impact the hammer 14 onto the engine under guard plate, thereby maximally simulating the real situation and achieving the test of the performance of the engine under guard plate.
[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
