Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] A functional testing device for an automotive electric drive control board includes a testing device body 1. An isolation mechanism 2 is provided on the front side of the testing device body 1 for isolating the interior and exterior of the testing device body 1. The isolation mechanism 2 includes:

[0026] The opening and closing unit 21 is located on the front side of the detection equipment body 1, and includes an isolation door 217 that is slidably installed on the front side of the detection equipment body 1. The isolation door 217 is slidably installed on the front side of the detection equipment body 1 to isolate the inside and outside of the detection equipment body 1 when it is working, thereby isolating external electromagnetic noise.

[0027] The positioning unit 22 is located on the right side of the isolation door 217 and is used to fix the position of the isolation door 217 when it closes the internal space of the detection equipment body 1.

[0028] By closing the sliding isolation door 217, external electromagnetic noise is blocked from coupling to the test signal line or the tested electric drive control board, thus solving the problems of unstable test results and increased misjudgment rate.

[0029] In this embodiment, a first track bar 211 and a second track bar 212 are fixedly installed on the front side of the detection device body 1. A first sliding seat 213 is slidably installed on the surface of the first track bar 211, and a connecting plate 214 is fixedly installed on the front side of the first sliding seat 213. A second sliding seat 215 is movably installed on the surface of the second track bar 212, and a base plate 216 is fixedly installed above the second sliding seat 215. The bottom of the connecting plate 214 is fixedly connected to the top of the isolation door 217, and the top of the base plate 216 is fixedly connected to the bottom of the isolation door 217. The sliding of the isolation door 217 is achieved by sliding the first sliding seat 213 and the second sliding seat 215.

[0030] The first track bar 211 and the second track bar 212 are respectively connected to the connecting plate 214 at the top and the base plate 216 at the bottom of the isolation door via the first sliding seat 213 and the second sliding seat 215, ensuring that the door moves without deviation.

[0031] In this embodiment, an observation window 218 is provided on the front side of the isolation door 217, through which the interior of the detection equipment body 1 can be observed and the detection status can be viewed.

[0032] It provides a visual window for the testing process, allowing observation of the internal testing status without opening the isolation door, thus avoiding frequent opening and closing that could damage the electromagnetic isolation environment.

[0033] In this embodiment, the positioning unit 22 includes a mounting base 223 fixedly installed on the right side of the isolation door 217, and an insert 224 fixedly installed on the right side of the mounting base 223. An installation box 221 is fixedly installed on the front side of the detection device body 1, and an installation plate 222 is fixedly installed on the left side of the installation box 221 by screws. The insert 224 is inserted into the interior of the installation box 221 through the through hole in the middle of the installation plate 222.

[0034] The insert 224 is precisely inserted into the mounting box 221 through the through hole of the mounting plate 222, simplifying the closing operation. The mounting plate 222, which is fixed with screws, allows for the maintenance and replacement of internal parts of the mounting box 221.

[0035] In this embodiment, the mounting box 221 has a fixedly installed socket 225 inside, and the rectangular plate 226 has a slidingly installed plug 227 inside. The plug block 224 has a socket 225 below it, and the plug 227 is driven by the driving component 3 to slide its upper end into the socket 225, thereby fixing the position of the plug block 224. The position of the isolation door 217 is fixed by the plug block 224 and the mounting base 223.

[0036] When the insert block 224 is inserted, its inclined surface pushes the insert post 227 downward, and the reset spring 33 then drives the insert post to insert into the insertion hole 225, thus achieving self-locking.

[0037] In this embodiment, the drive assembly 3 includes a fixed plate 31 fixedly installed inside the mounting box 221, and the insertion post 227 slides inside the fixed plate 31. A baffle 34 is fixedly installed on the surface of the insertion post 227, and a return spring 33 is installed on the surface of the insertion post 227. The return spring 33 is located between the baffle 34 and the fixed plate 31. A rectangular groove 32 is opened on the front side of the fixed plate 31. A connecting rod 35 is fixedly installed on the front side of the bottom end of the insertion post 227, and the connecting rod 35 slides inside the rectangular groove 32. One end of the rectangular groove 32 passes through the rectangular groove 32 and a push block 36 is fixedly installed thereon.

[0038] Pushing the push block 36 pulls down the insert post 227 via the connecting rod 35, releasing the fixation of the insert block 224, making the operation simple.

[0039] The return spring 33 provides elastic force between the retaining plate 34 and the fixing plate 31 to ensure that the insert 227 remains locked under normal conditions.

[0040] The rectangular groove 32 restricts the sliding path of the connecting rod 35.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] During operation, firstly, the electric drive control board is placed on the needle bed inside the main body 1 of the detection equipment. The user pushes the isolation door 217 to slide, so that the insert block 224 is inserted into the interior of the mounting box 221 through the through hole of the mounting plate 222. The inclined surface of the insert block 224 contacts the top of the insert post 227, pushing the insert post 227 to move downward. The insert post 227 drives the baffle 34 to squeeze the return spring 33. Then, the return spring 33 pushes the baffle 34 with its own elasticity, driving the insert post 227 to be inserted into the interior of the insertion hole 225, thus fixing the position of the isolation door 217.

[0043] Then, the user pulls the push block 36 to move the connecting rod 35, which in turn moves the insertion post 227 downward. One end of the insertion post 227 is pulled out of the insertion hole 225, and the isolation door 217 is pushed to open the interior of the detection equipment body 1, allowing the user to retrieve the internal electric drive control board.
