Description

When performing other tests on the wiring harness, such as thermal shock, the operator needs to reinstall the wiring harness for testing, which can easily cause burns to the operator. Therefore, we propose an accelerated aging simulation testing equipment for automotive wiring harnesses. Utility Model Content

[0039] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0040] Example:

[0041] like Figures 1-5 As shown, the automotive wiring harness aging simulation accelerated testing equipment includes:

[0042] Mounting base 1 has symmetrical support blocks at its bottom end, a water storage cavity inside, and a water pump. A through groove is provided on one side of its front surface.

[0043] The testing chamber 2 is fixedly mounted on the top of the mounting base 1. A rectangular through slot is provided on the top of the chamber, and threaded holes are provided symmetrically.

[0044] The drive adjustment mechanism 3 is connected and is bolted to the top of the detection chamber 2;

[0045] The connecting clamping mechanism 4 is fixedly mounted at the output end of the connecting drive adjustment mechanism 3;

[0046] The fixed partition plate 5 is fixedly installed in the middle of the inner side of the connecting detection chamber 2, and the top is provided with a groove that is compatible with the connecting clamping mechanism 4.

[0047] The filter mechanism 6 is connected and is movably inserted into the through groove on one side of the front surface of the mounting base 1;

[0048] Heating wire 7 is fixedly installed on one side inside the connecting detection chamber 2;

[0049] The water spray pipe 8 is fixedly installed on the other side of the inside of the connection test chamber 2, and is connected to the water pump inside the mounting base 1 through a pipe.

[0050] The working principle of the above technical solution is as follows:

[0051] During use, the wire harness is first installed inside the connecting clamping mechanism 4, so that the wire harness is inside the connecting detection chamber 2. Then, the connecting detection chamber 2 is closed, so that the heating wire 7 heats the wire harness, enabling high-temperature testing. Then, the connecting drive adjustment mechanism 3 adjusts the position of the connecting clamping mechanism 4, moving the wire harness to the other side inside the connecting detection chamber 2. Then, under the action of the water pump and pipes, water is sprayed out through the connecting spray water distribution pipe 8 to quickly cool the wire harness, thereby performing thermal shock testing on the wire harness. At the same time, the water can be filtered by the connecting filter mechanism 6 and then flow back to the inside of the mounting base 1 for water recycling, making the operation convenient.

[0052] In another embodiment, such as Figure 3 As shown, the connecting drive adjustment mechanism 3 includes a first support leg 31, a first connecting mounting frame 32 is fixedly connected to the end of the first support leg 31, an output motor 33 is fixedly connected to one end of the first connecting mounting frame 32, a first connecting threaded rod 34 is fixedly connected to the output end of the output motor 33, and a movable mounting block 35 is movably connected to the outer surface of the first connecting threaded rod 34 via a thread.

[0053] The output motor 33 drives the first connecting threaded rod 34, so that when the first connecting threaded rod 34 rotates, the movable mounting block 35 can move on the outer side of the surface of the first connecting threaded rod 34 and on the inner side of the first connecting mounting frame 32, thereby adjusting the position of the connecting clamping mechanism 4 and the wire harness, which is convenient to operate.

[0054] In another embodiment, such as Figure 3 As shown, the connecting clamping mechanism 4 includes a connecting mounting bracket 41 fixedly disposed at the bottom of the movable mounting block 35, and a connecting clamping assembly 42 is symmetrically disposed on the inner side of the connecting mounting bracket 41 by bolts.

[0055] The connection mounting bracket 41 and the connection clamping assembly 42 can move with the movable mounting block 35, and the wire harness can be stably held between the connection clamping assembly 42 and the connection mounting bracket 41 for easy installation.

[0056] In another embodiment, such as Figure 2 and Figure 3 As shown, the outer surface of the connecting mounting bracket 41 slides and fits against the inner side of the rectangular through groove at the top of the connecting detection chamber 2, and fits against the inner side of the groove at the top of the fixed partition plate 5.

[0057] The mounting bracket 41 can move stably inside the rectangular through groove at the top of the connection and testing chamber 2, and can also move stably inside the top groove of the fixed partition plate 5, making operation convenient.

[0058] In another embodiment, such as Figure 4 As shown, the connecting clamping assembly 42 includes a second leg 421. One end of the second leg 421 is fixedly connected to a connecting mounting block 422. A movable connecting rod 423 is movably connected inside the connecting mounting block 422. One end of the movable connecting rod 423 is fixedly connected to a connecting pressing block 424. The other end of the movable connecting rod 423 is fixedly connected to a second connecting threaded rod 425. A connecting sleeve plate 426 is movably sleeved on the outer surface of the second connecting threaded rod 425. A fastening nut 427 is threadedly connected to the outer surface of the second connecting threaded rod 425. A third leg 428 is bolted to one side of the connecting mounting block 422. One end of the third leg 428 is fixedly connected to a connecting sleeve block 429. A force spring 4210 is provided inside the connecting sleeve block 429. One end of the force spring 4210 is in contact with one side of the connecting sleeve plate 426. A drainage hole 4211 is provided at the bottom of the connecting sleeve block 429.

[0059] It is convenient to place the wire harness between the connecting compression block 424 and the connecting mounting bracket 41. Under the action of the force spring 4210, the connecting sleeve plate 426 can be pushed, which drives the movable connecting rod 423 and the connecting compression block 424 to be pushed, so that the connecting compression block 424 and the connecting mounting bracket 41 cooperate to clamp and fix the wire harness, which is convenient to operate.

[0060] In another embodiment, such as Figure 5 As shown, one end of the connecting extrusion block 424 has a bevel, and the outer edge of the connecting sleeve plate 426 slides and fits against the inner side of the connecting sleeve block 429.

[0061] To facilitate the installation of the wire harness, the wire harness is moved along the inclined plane, causing it to compress the connecting compression block 424. This causes the connecting compression block 424 to move the movable connecting rod 423, the second connecting threaded rod 425, the fastening nut 427, and the connecting sleeve plate 426, compressing the force spring 4210 until the wire harness is positioned between the connecting compression block 424 and the connecting mounting bracket 41. This method is convenient and ensures that the connecting sleeve plate 426 can move stably inside the connecting sleeve block 429.

[0062] In another embodiment, such as Figure 2As shown, the connecting filter mechanism 6 includes a second connecting mounting frame 61, a filter plate 62 is fixedly connected to the inner side of the second connecting mounting frame 61, a connecting end plate 63 is fixedly connected to one end of the second connecting mounting frame 61, and a connecting handle 64 is fixedly connected to the surface of the connecting end plate 63.

[0063] The filter plate 62 facilitates the filtration of water used to cool the wire harness, and also makes it easy to pull the connecting handle 64 to disassemble the connecting end plate 63, the second connecting mounting frame 61, and the filter plate 62, allowing for the cleaning of impurities inside. The operation is convenient and quick.

[0064] The working principle of this utility model is as follows: During use, the wire harness is first installed and moved along the inclined plane, causing it to compress the connecting compression block 424. This causes the connecting compression block 424 to move the movable connecting rod 423, the second connecting threaded rod 425, the fastening nut 427, and the connecting sleeve 426, compressing the force spring 4210 until the wire harness is between the connecting compression block 424 and the connecting mounting bracket 41. At this point, under the action of the force spring 4210, the connecting sleeve 426 is pushed, causing the movable connecting rod 423 and the connecting compression block 424 to move, allowing the connecting compression block 424 to engage with the connecting mounting bracket 41 to clamp and fix the wire harness. The connection detection chamber 2 is then closed, allowing the heating wire 7 to operate and provide heating. Heat treatment is performed on the wire harness for high-temperature testing. After the high-temperature test, the output motor 33 drives the first connecting threaded rod 34, causing the movable mounting block 35 to move on the outer side of the surface of the first connecting threaded rod 34 and the inner side of the first connecting mounting frame 32. This adjusts the position of the connecting clamping mechanism 4 and the wire harness, moving the wire harness to the other side of the connecting test chamber 2. Then, the water pump and pipes inside the mounting base 1 spray water out through the connecting water spraying pipe 8 to quickly cool the wire harness, thus enabling thermal shock testing. The water sprayed through the connecting water spraying pipe 8 is filtered by the filter plate 62 and then collected and treated again. The overall structure is simple and the operation is convenient and quick.

[0065] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
