Detailed implementation manners

[0030] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0031] Please refer to Figures 1-4 As shown, in this embodiment, a power module protection device is provided, including a box body 1, and a power module body 102 is placed inside the box body 1;

[0032] A cover plate 2 located above the power module body 102, and clamping plates 201 are installed at both ends of the cover plate 2;

[0033] Two U-shaped plates 3, a threaded rod 304 with opposite thread directions on both sides is rotatably fitted on one side of the U-shaped plate 3, both ends of the threaded rod 304 are threadedly fitted with T-shaped plates 306, and one end of the T-shaped plate 306 is clamped and fitted with one side of the clamping plate 201.

[0034] Working principle:

[0035] First, place the cover plate 2 inside the box body 1, then place the U-shaped plate 3 around the clamping plate 201, and then rotate the threaded rod 304. The threaded rod 304 drives the two T-shaped plates 306 to slide. Since the thread directions on both sides of the threaded rod 304 are opposite, the T-shaped plates 306 position the cover plate 2 inside the box body 1 through the clamping plates 201.

[0036] A set T-shaped plate 306 is provided, so that the T-shaped plate 306 slides under the action of the threaded rod 304, so that one end of the T-shaped plate 306 slides into and out of the inside of the clamping plate 201, so as to realize that one end of the T-shaped plate 306 fixes and releases the fixing of the cover plate 2 through the clamping plate 201, reducing the problem that the connecting spring repeatedly elongates and shortens when being subjected to vibration impact in the prior art, reducing the problem that one end of the plug slides out of the inside of the cover plate 2, and improving the stability of the cover plate 2 when placed.

[0037] In order to make the sliding process of the T-shaped plate 306 on one side of the U-shaped plate 3 in this embodiment more stable, the following structure is improved, as Figures 1-4 As shown, a groove 301, two through holes 302 and two guide grooves 303 are provided on one side of the U-shaped plate 3 in this embodiment. The adjacent guide grooves 303 communicate with the through holes 302, and the through holes 302 communicate with the groove 301. The threaded rod 304 is rotationally fitted inside the groove 301, the through hole 302 and the guide groove 303. An annular plate 305 is installed in the middle of the threaded rod 304. The T-shaped plate 306 is slidably fitted inside the guide groove 303. A threaded hole 309 is provided on one side of the T-shaped plate 306. The threaded hole 309 is threadedly fitted with the threaded rod 304. A guide rod 308 is installed inside the guide groove 303. A guide hole 307 is provided on one side of the T-shaped plate 306. One end of the guide rod 308 is located inside the guide hole 307. Card slots 202 are provided at both ends of the clamping plate 201. One end of the T-shaped plate 306 is located inside the card slot 202. Placing grooves 101 are provided on both sides of the box body 1. The U-shaped plate 3 and the clamping plate 201 are both located inside the placing groove 101. The thickness of the clamping plate 201 is less than the thickness of the cover plate 2.

[0038] When this embodiment is in use, first rotate the annular plate 305. The annular plate 305 drives the threaded rod 304 to rotate inside the through hole 302. One end of the threaded rod 304 drives the T-shaped plate 306 to slide inside the guide groove 303 through the threaded hole 309. The T-shaped plate 306 slides on the periphery of the guide rod 308 through the guide hole 307. The T-shaped plate 306 fixes the clamping plate 201 through the card slot 202.

[0039] The provided guide hole 307 enables the T-shaped plate 306 to slide on the guide rod 308 through the guide hole 307 under the action of the threaded rod 304, and guides the sliding direction of the T-shaped plate 306 through the guide hole 307, reducing the problem that the T-shaped plate 306 tilts when sliding, and improving the stability of the T-shaped plate 306 when sliding.

[0040] In order to make the placement process of the power module body 102 in this embodiment more stable, the following structure is improved, as Figures 1-4As shown in the figure, on both sides of the power module body 102 of this embodiment, a first clamping plate 103 and a second clamping plate 104 are respectively provided. A plurality of first springs 105 are installed between the first clamping plate 103 and the cover plate 2, and a plurality of second springs 106 are installed between the second clamping plate 104 and the inner side wall of the box body 1. With the first springs 105 and the second springs 106 provided, when the power module body 102 shakes, the first springs 105 and the second springs 106 provided can reduce the amplitude of the shake of the power module body 102.
