[0002] Good toughness in automotive parts can improve vehicle safety. If the parts are of poor quality, they are more likely to break in the event of an accident, and the broken fragments can easily injure the driver. Therefore, before leaving the factory, factory workers test the toughness of automotive parts. Currently, the testing is generally done by pressing. Workers place the automotive parts on a pressing table, and then start the equipment. The pressure bar inside the equipment presses the automotive parts. If the parts break, it indicates poor toughness; otherwise, it indicates good toughness. However, this method involves manual loading and unloading at close range, which is quite troublesome, and the flying fragments from broken parts can easily injure workers, resulting in poor safety.

Detailed Implementation
[0036] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.
[0037] Example 1
[0038] A toughness testing device for new energy vehicle components, such as Figure 1-18 As shown, it includes a main frame 1, first fixed posts 3, first fixed plates 4, pressure plates 5, first sliding rods 6, first linear springs 7, a detection mechanism 8, and an isolation mechanism 9. Two first fixed posts 3 are welded to the top front side of the main frame 1. The first fixed posts 3 are arranged symmetrically on the left and right. A first fixed plate 4 is provided between the bottom of the two first fixed posts 3. The first fixed plate 4 is an n-shaped plate. Two first sliding rods 6 are slidably connected to the left and right sides of the middle of the first fixed plate 4. A pressure plate 5 is connected between the tops of the four first sliding rods 6. A first linear spring 7 is sleeved on the upper part of each of the four first sliding rods 6. The two ends of the four first linear springs 7 are welded to the first fixed plate 4 and the pressure plate 5, respectively. A detection mechanism 8 is provided on the top of the main frame 1, and an isolation mechanism 9 is provided on the front side of the main frame 1.
[0039] The detection mechanism 8 includes a contact switch 81, a second fixed column 82, a first electric push rod 83, a pressure rod 84, a first sensing rod 85, and a first distance sensor 86. The contact switch 81 is located on the top rear side of the main frame 1. The second fixed column 82 is welded to the upper front side of the main frame 1. The first electric push rod 83 is located in the middle of the second fixed column 82. The bottom of the telescopic rod of the first electric push rod 83 is connected to the pressure rod 84 through a coupling. The first sensing rod 85 is located on the upper front side of the pressure rod 84. The first distance sensor 86 is located on the upper front side of the main frame 1. The first distance sensor 86 is located in front of the second fixed column 82.
[0040] The isolation mechanism 9 includes a fixed rod 91, a second sliding rod 92, a second linear spring 93, and a folding curtain 94. Two fixed rods 91 are welded to the front side of the main frame 1. The fixed rods 91 are arranged symmetrically up and down. Two second sliding rods 92 are slidably arranged between the two fixed rods 91. The second sliding rods 92 are arranged symmetrically left and right. A folding curtain 94 is connected between the two second sliding rods 92. A second linear spring 93 is sleeved in the middle of each of the two fixed rods 91. The two ends of the two second linear springs 93 are respectively connected to the two second sliding rods 92.
[0041] When staff need to test the toughness of new energy vehicle components, they power on the device by pressing the main power switch. The staff then manually moves the second slide bar 92 on the left to the right, or the second slide bar 92 on the right to the left. This compresses the second linear spring 93, folding the curtain 94. Next, the staff manually moves the pressure plate 5 upwards, causing the first slide bar 6 to move upwards. This stretches the first linear spring 7, pushing the vehicle component under the pressure plate 5. Releasing the pressure plate 5 releases the first linear spring 7, causing the pressure plate 5 and the first slide bar 6 to move downwards and reset, thus pressing the vehicle component down. This prevents the vehicle component from shifting during testing, which could lead to test failure. After the pressure plate 5 has pressed the vehicle component down, releasing the second slide bar 92 resets the second linear spring 93, causing the second slide bar 92 to reset as well, allowing the curtain 94 to unfold. This prevents the vehicle component from shifting during testing. During the testing of automotive parts, parts with poor toughness may break and scatter when crushed. Manually pressing the contact switch 81 activates the first electric push rod 83 after three seconds. The extension rod of the first electric push rod 83 moves the pressure rod 84 downwards, which in turn moves the first sensing rod 85 downwards. When the pressure rod 84 contacts the automotive part, it presses down on the part. The first distance sensor 86 detects that the distance between itself and the first sensing rod 85 has reached a preset value. The control module then retracts the first electric push rod 83 for one second to reset. The extension rod of the first electric push rod 83 then moves the pressure rod 84 and the first sensing rod 85 upwards to reset. The condition of the automotive part is then observed. If the part breaks, it indicates poor toughness; if there is only slight deformation, it indicates good toughness. After testing, the automotive part can be removed. When no longer needed, simply press the main power switch to disconnect the device.
[0042] It also includes a feeding mechanism 10, which includes a third fixed column 101, a second electric push rod 102, a first push rod 103, a push plate 104, a storage frame 105, a second sensing rod 106, and a second distance sensor 107. Two third fixed columns 101 are installed on the rear side of the bottom of the main frame 1 by screws. The upper part of the two third fixed columns 101 is connected to the second electric push rod 102. The front side of the telescopic rod of the second electric push rod 102 is connected to the first push rod 103. The push plate 104 is welded to the upper rear side of the first push rod 103. The storage frame 105 is welded to the upper rear side of the main frame 1. The second sensing rod 106 is provided on the rear side of the first push rod 103. The second distance sensor 107 is provided on the rear side of the inner wall of the main frame 1.
[0043] The staff places the automotive parts to be inspected into the storage box 105, then presses the contact switch 81. The control module also controls the second electric push rod 102 to start. The extension rod of the second electric push rod 102 drives the first push rod 103 to move forward, which in turn drives the push plate 104 and the second sensing rod 106 to move forward. This causes the push plate 104 to move the automotive parts forward to below the pressure plate 5. The second distance sensor 107 detects that the distance between itself and the second sensing rod 106 has reached a preset value. The control module controls the extension rod of the second electric push rod 102 to retract for one second to reset. The extension rod of the second electric push rod 102 drives the first push rod 103, the push plate 104, and the second sensing rod 106 to move backward to reset. After pressing is completed, when the first distance sensor 86 detects that the distance between itself and the first sensing rod 106 has reached a preset value, the second electric push rod 102 retracts for one second to reset. The second electric push rod 102 then drives the first push rod 103, the push plate 104, and the second sensing rod 106 to move backward to reset. When the distance between the push rods 85 reaches the preset value, the control module will also control the second electric push rod 102 to start, so that the extension rod of the second electric push rod 102 will drive the first push rod 103, the push plate 104 and the second sensing rod 106 to move forward again, so that the push plate 104 will drive the new car parts to move forward. When the second distance sensor 107 detects that the distance between itself and the second sensing rod 106 has reached the preset value again, the control module controls the extension rod of the second electric push rod 102 to retract for one second to reset, and at the same time controls the first electric push rod 83 to start. This cycle can continuously detect car parts, thereby improving the working efficiency of the device. After the detection is completed, press the contact switch 81 again, and the control module will control the first electric push rod 83 and the second electric push rod 102 to stop operating.
[0044] It also includes a release mechanism 11, which includes a second push rod 111, a third slide rod 112, a first wedge block 113 and a second wedge block 114. The second push rod 111 is provided on the lower front side of the push plate 104. Two third slide rods 112 are welded to the rear top of the main frame 1. The third slide rods 112 are arranged symmetrically on the left and right. The left and right sides of the second push rod 111 are slidably connected to the third slide rods 112 on the same side. The left and right sides of the front side of the second push rod 111 are provided with first wedge blocks 113. The left and right sides of the pressure plate 5 are fixed with second wedge blocks 114 by bolts. The two second wedge blocks 114 are in contact with the first wedge blocks 113 on the same side.
[0045] When the pusher plate 104 moves forward, it drives the second push rod 111 to move forward, which in turn drives the first wedge block 113 to move forward. The first wedge block 113 drives the second wedge block 114 to move upward, which in turn drives the pressure plate 5 to move upward. At this time, the first linear spring 7 is stretched, so there is no need for the operator to manually control the pressure plate 5 to move upward, reducing the difficulty of operation. Then the pusher plate 104 pushes the car parts under the pressure plate 5. The pusher plate 104 moves backward to reset, driving the second push rod 111 and the first wedge block 113 to move backward to reset. At this time, the first linear spring 7 resets, driving the pressure plate 5 and the second wedge block 114 to reset, so that the pressure plate 5 clamps and fixes the car parts, which is convenient for subsequent inspection of the car parts.
[0046] It also includes a protective mechanism 12, which includes a rotating shaft 121, an indicator light 122, a material support frame 123, a second fixing plate 124, a fourth sliding rod 125, a third linear spring 126, a sliding plate 127, a shock-absorbing plate 128, a pressure block 129, and a pressure sensor 1210. The rotating shaft 121 is connected to the middle of the main frame 1 through a bearing seat. An indicator light 122 is located in the middle of the top of the main frame 1. A material support frame 123 is located in the middle of the rotating shaft 121. A second fixing plate 124 is located on both the left and right sides of the material support frame 123. Both second fixing plates 124 slide on each other. The system is connected by four fourth slide rods 125. Each of the four fourth slide rods 125 on the same side is connected to a shock-absorbing plate 128. Each of the eight fourth slide rods 125 is fitted with a third linear spring 126. The two ends of the eight third linear springs 126 are welded to the fourth slide rods 125 on the same side and the second fixing plate 124 on the same side, respectively. A sliding plate 127 is connected between the bottom front side of the first fixing plate 4 and the inside front side of the main frame 1. A pressure block 129 is provided in the middle of the left side of the shock-absorbing plate 128 on the left side. A pressure sensor 1210 is provided in the middle of the right side of the second fixing plate 124 on the left side.
[0047] It also includes a material pouring mechanism 13, which includes a photoelectric sensor 131, a fourth fixed column 132 and a geared motor 133. The photoelectric sensor 131 is provided on the upper front side of the storage frame 105. The fourth fixed column 132 is welded to the left side of the main frame 1. The geared motor 133 is provided in the middle of the fourth fixed column 132. The output shaft of the geared motor 133 is connected to the left side of the rotating shaft 121 through a coupling.
[0048] The broken car part falls into the support frame 123. It contacts the shock absorber 128, causing it to move downwards, which in turn moves the fourth slide bar 125 downwards. At this time, the third linear spring 126 is stretched. The shock absorber 128 acts as a buffer, preventing the broken car part from damaging the device due to the large impact force. The left shock absorber 128 moves the pressure block 129 downwards until it contacts the pressure sensor 1210. The pressure sensor 1210 detects that the pressure has reached a preset value, and the control module indicator light 122 illuminates. Simultaneously, the broken car part slides down the shock absorber 128 into the support frame 123. At this time, the third linear spring 126 resets, causing the fourth slide bar 125 and the shock absorber 128 to reset. After the left shock absorber 128 and the pressure block 129 reset, the pressure sensor 1210 detects the pressure return. When the initial value is reached, the control module controls the indicator light 122 to turn off. When the photoelectric sensor 131 detects that the light is bright enough to reach the preset value, the control module controls the reduction motor 133 to rotate for two seconds, and then reverses for two seconds to reset. The output shaft of the reduction motor 133 drives the rotating shaft 121 to rotate, which in turn drives the material support frame 123, the second fixing plate 124, the fourth sliding rod 125, the shock absorber 128, the pressure block 129 and the pressure sensor 1210 to rotate forward. This causes the material support frame 123 to pour the broken car parts onto the sliding plate 127, so that the broken car parts slide into the frame prepared by the staff. In this way, the broken car parts can be collected in a concentrated manner. After two seconds, the output shaft of the reduction motor 133 drives the rotating shaft 121, the material support frame 123, the second fixing plate 124, the fourth sliding rod 125, the shock absorber 128, the pressure block 129 and the pressure sensor 1210 to reverse and reset.
[0049] It also includes a control box 2, which is located on the lower left side of the main frame 1. The control box 2 includes a battery, a power module, and a control module. The battery supplies power to the entire new energy vehicle component toughness testing device. The battery output terminal is electrically connected to the power module. The power module is connected to the main power switch via a line. The power module is electrically connected to the control module. The control module is connected to a DS1302 clock circuit and a 24C02 circuit. The first distance sensor 86, the second distance sensor 107, the pressure sensor 1210, the contact switch 81, the photoelectric sensor 131, and the indicator light 122 are all electrically connected to the control module. The geared motor 133 is connected to the control module via a DC motor forward and reverse rotation module. The first electric push rod 83 and the second electric push rod 102 are both connected to the control module via a relay control module.
