Technical Field

[0001] The utility model relates to the technical field of power modules, in particular to a waterproof power module. Background Art

[0002] A power module is a functional module that integrates power electronic devices and related circuits. It's like a small power "hub." For example, in a motor drive system, the power module processes input electrical energy. Through the switching action of internal devices such as insulated-gate bipolar transistors (IGBTs) or metal-oxide semiconductor field-effect transistors (MOSFETs), it changes the form of electrical energy according to control signals, such as converting direct current to alternating current. It can also control the output power to meet the needs of different motor operating conditions. Due to its high level of integration, it can simplify circuit design, reduce equipment size, and improve reliability. It is widely used in industrial automation, new energy vehicles, power systems, and other fields.

[0003] Existing power modules still have some shortcomings in practical applications. First, power modules are a common module in power distribution equipment, but the wiring ports of existing power modules have poor waterproof and moisture-proof performance. In some special places, such as places with heavy rain or some places with perennial humidity, the docking structure inside the power module wiring port will corrode, resulting in rust, which will lead to the deterioration of the functional effect of the power module and affect the service life of the power module.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a waterproof power module, including a main body 1, a mounting base 2 is fixedly installed on the outer wall of the main body 1, a wiring port 3 is fixedly installed on the outer wall of the main body 1, a sealing mechanism 4 is provided on the outer wall of the main body 1, and a fixing mechanism 5 is provided on the outer wall of the main body 1.

[0021] The sealing mechanism 4 includes: a slide groove 401, a slider 402, a hinged rod 403, a groove 404, a round rod 405, a V-groove rod 406, a connecting rod 407, a round block 408, and an arc-shaped sealing strip 409. The slide groove 401 is provided on the inner wall of the main body 1, the slider 402 slides on the inner wall of the slide groove 401, the side wall of the slider 402 is hinged with the hinged rod 403, the inner wall of the main body 1 is provided with a groove 404, the inner wall of the groove 404 is slidably installed with a round rod 405, one end of the hinged rod 403 is hinged to the side wall of the slider 402, and the other end of the hinged rod 403 is hinged to the outer wall of the round rod 405, the end of the round rod 405 is fixedly installed with a V-groove rod 406, the inner wall of the main body 1 is slidably installed with a connecting rod 407, the upper surface of the connecting rod 407 is fixedly installed with a round block 408, the outer wall of the round block 408 is aligned with the inner wall of the V-groove rod 406 The walls are in a fitted shape, and there are four groups of connecting rods 407, which are symmetrically arranged in pairs with the center line of the main body 1 in the vertical direction as the axis of symmetry, and the upper surfaces of the four groups of connecting rods 407 are fixedly installed with round blocks 408. The ends of the connecting rods 407 are fixedly installed with arc-shaped sealing strips 409, which push the slider 402 to slide inward on the inner wall of the slide groove 401. When the slider 402 slides inward, the hinged rod 403 will push the round rod 405 to slide to the right on the inner wall of the groove 404, and push the V-groove rod 406 to slide to the right. When the V-groove rod 406 slides to the right, the V-groove rod 406 will squeeze the round block 408 so that the round block 408 drives the arc-shaped sealing strips 409 at the ends of the two groups of connecting rods 407 to approach each other and seal the wiring port 3 to prevent moisture from entering the wiring port 3, causing the wiring port 3 to corrode and rust, thereby affecting the service life of the power module.

[0022] The above-mentioned fixing mechanism 5 includes: a long slot 501, a fixing rod 502, a rubber positioning block 503, a short rod 504, and an auxiliary positioning block 505. The long slot 501 is opened on the side wall of the main body 1, and the fixing rod 502 is slidably installed on the inner wall of the long slot 501. The end of the fixing rod 502 is fixedly installed with a rubber positioning block 503. The rubber positioning block 503 is arc-shaped, and the outer wall of the rubber positioning block 503 is hinged with a short rod 504. One end of the short rod 504 is hinged to the outer wall of the rubber positioning block 503, and the other end of the short rod 504 is hinged to the outer wall of the connecting rod 407. The outer wall of the main body 1 is fixedly installed with an auxiliary positioning block 505. The short rod 504 pushes the rubber positioning block 503 to slide downward on the inner wall of the long slot 501 and cooperates with the auxiliary positioning block 505 to fix the wire to prevent the wire from loosening and affecting the normal use of the power module.

[0023] Working principle: By inserting the wire into the wiring port 3, the slider 402 is pushed at this time so that the slider 402 slides inward on the inner wall of the slide groove 401. At the same time as the slider 402 slides inward, the hinged rod 403 pushes the round rod 405 to slide to the right on the inner wall of the groove 404 and pushes the V-groove rod 406 to slide to the right as well. At the same time as the V-groove rod 406 slides to the right, the V-groove rod 406 squeezes the round block 408 so that the round block 408 drives the arc-shaped sealing strips 409 at the ends of the two sets of connecting rods 407 to approach each other and seal the wiring port 3 to prevent moisture from entering the wiring port 3, causing corrosion and rust at the wiring port 3, thereby affecting the service life of the power module. At the same time as the two sets of connecting rods 407 approach each other, the short rod 504 pushes the rubber positioning block 503 to slide downward on the inner wall of the long groove 501 and assemble The auxiliary positioning block 505 is combined to fix the wire to prevent the wire from loosening and affecting the normal use of the power module. When the wire needs to be removed, the slider 402 is pulled to slide outward on the inner wall of the slide groove 401. While the slider 402 slides outward, the hinged rod 403 pulls the round rod 405 to slide to the left on the inner wall of the groove 404 and pulls the V-groove rod 406 to slide to the left. While the V-groove rod 406 slides to the left, the V-groove rod 406 squeezes the round block 408 and causes the two sets of connecting rods 407 to slide on the inner wall of the main body 1 and causes the two sets of arc-shaped sealing strips 409 to move away from each other to release the seal. While the two sets of connecting rods 407 move away from each other, the short rod 504 pulls the rubber positioning block 503 to slide upward on the inner wall of the long groove 501 to release the fixation.

[0024] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
