Power module with shock protection

Abstract

This utility model discloses a power module with shock absorption and protection function, including a housing, a protective box, a power supply body, and a shock absorption mechanism disposed on the inside of the housing. The shock absorption mechanism includes lateral shock absorbers, compression plates, compression springs, a base, a vertical shock absorber, a support spring, and a limiting ring. A lead screw drives a drive rod to move, thereby adjusting the position of the clamping plate, allowing the power module to meet the needs of various power supply body specifications, enriching the functionality of the power module. During operation, multiple lateral shock absorbers and multiple compression springs work together to buffer lateral impacts on the power module, while the vertical shock absorber and support spring work together to buffer vertical impacts. The retaining ring limits the movement trajectory of the base to prevent the base from detaching from the bottom of the housing, thereby providing shock absorption and protection against multi-directional impacts on the power module and improving the protection effect of the power module.

[0038] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] Example 1:

[0040] like Figure 1-5As shown, a power module with shock absorption and protection function includes a housing 100, a protective box 200 installed inside the housing 100, a power supply body 300 installed in the middle of the protective box 200, and a shock absorption mechanism disposed inside the housing 100 for shock absorption and protection of the power module. The shock absorption mechanism includes a lateral shock absorber 101, which is fixed to the outer wall of the protective box 200 by bolts. One end of the lateral shock absorber 101 is fixed to a compression plate 102 by bolts, and the outer side of the lateral shock absorber 101 is fixed to a compression plate 102 by bolts. A compression spring 103 is fixedly attached. A base 104 is slidably connected to the bottom of the housing 100. A retaining ring 110 is bolted to the top of the base 104, limiting the movement of the base 104 and preventing it from detaching from the bottom of the housing 100. A vertical shock absorber 105 is bolted to the top of the base 104. The lateral shock absorber 101 and the vertical shock absorber 105 convert impact energy into heat energy. A support spring 107 is bolted to the outer side of the vertical shock absorber 105. The support spring 107 and the compression spring 103 are connected to the bottom of the housing 100. Spring 103 absorbs impact force. A limit ring 108 is bolted to the bottom of the housing 100. Multiple ventilation holes 400 are evenly cut on both sides of the housing 100 to dissipate heat from the power module. A dustproof mesh 500 is bolted inside each ventilation hole 400 to prevent dust from entering the housing 100. A clamping mechanism is also included on one side of the protective box 200 for mounting and securing the power module. The clamping mechanism includes a frame 201, which is bolted... A lead screw 202 is rotatably connected to the middle position of the frame 201, which is fixed to the outer wall of the protective box 200. A drive rod 203 is driven to the outer side of the lead screw 202. A square hole is cut on the outer side of the protective box 200 to limit the drive rod 203. One end of the drive rod 203 is fixed to a clamping plate 204 by bolts. A rubber pad 210 is pasted on the inner wall of the clamping plate 204 to prevent damage to the surface of the power module. One end of the lead screw 202 is fixed to a turntable 220 by bolts, and the turntable 220 drives the lead screw 202 to rotate.

[0041] In this embodiment, the operator rotates the turntable 220, which drives the drive rod 203 to move via the lead screw 202, thereby adjusting the position of the clamping plate 204. This allows the power module to be used with power supply bodies 300 of various specifications, enriching the functionality of the power module. During operation, multiple lateral shock absorbers 101 and multiple compression springs 103 work together to buffer the lateral impact of the power module. Vertical shock absorbers 105 and support springs 107 work together to buffer the vertical impact of the power module. The retaining ring 110 limits the movement trajectory of the base 104 to prevent the base 104 from detaching from the bottom of the housing 100, thereby providing shock absorption and protection against multi-directional impacts on the power module and improving the protection effect of the power module.

[0042] Example 2:

[0043] like Figure 1-7 As shown, a power module with shock absorption and protection function is provided. The bottom of the housing 100 is equipped with a mounting mechanism for fixing the housing 100. The mounting mechanism includes a track 301, which is fixed to the bottom of the housing 100 by bolts. A slider 302 is slidably connected to the inner wall of the track 301, and the slider 302 slides along the track 301. A support leg 303 is welded to one side of the slider 302, and a bolt hole 304 is cut in the middle of the support leg 303. The box 100 is fixed by bolt holes 304. The top of the box 100 is provided with an opening and closing mechanism for opening or closing the box 100. The opening and closing mechanism includes a box cover 401, which is installed on the top of the box 100. The outer side of the box cover 401 is evenly cut with grooves 402. A nut 403 is welded to the outer side of the box cover 401. The nut 403 is internally threaded with a screw 404, and the screw 404 is clearance-fitted with the groove 402.

[0044] In this embodiment, the operator slides the slider 302 along the track 301 to adjust the position of the support foot 303, so that the power module can be fixedly installed in multiple positions during operation. When maintenance is required, the screw 404 is turned to remove the screw 404 from the nut 403, so as to quickly install the cover 401, which improves the convenience of power module maintenance.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
