[0002] The IPM module, short for Intelligent Power, is an advanced power switching device that offers the advantages of high current density, low saturation voltage, and high voltage resistance, as well as high input impedance, high switching frequency, and low drive power. Furthermore, the IPM integrates logic, control, detection, and protection circuits, making it easy to use. This not only reduces system size and development time, but also significantly enhances system reliability, adapting to the current development trends of power devices.

[0003] The inventors believe that the following defects often exist: when the IPM module is packaged, due to the different lengths of the IPM module pins, different packaging structures are required to protect the IPM module, which increases the cost of manufacturing the IPM module packaging structure; therefore, to address the above problems, an intelligent IPM module packaging structure is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when the IPM module is packaged, different packaging structures are required to protect the IPM module due to the different lengths of the IPM module pins, which increases the manufacturing cost of the IPM module packaging structure, and to propose an intelligent IPM module packaging structure.

[0006] The effect achieved by the above components is: it achieves the effect of encapsulating pins of different lengths of the IPM module, avoids the situation where the IPM module pins are too long and the IPM module is placed in the packaging box. Since the IPM module pins need to be placed on the placement board and then the packaging box is sealed, the pins are squeezed by the box cover and caused to bend, thereby improving the practicality of the device.

[0007] Preferably, the inner surface of the box cover, the surface of the placement plate and the support table are all fixedly connected with a protective pad, and the material of the protective pad is silicone.

[0008] The effects achieved by the above components are: achieving the effect of multi-directional protection of the IPM module, avoiding damage to the IPM module, and improving the practicality of the device.

[0009] Preferably, the arc surface of the sliding rod is covered with a spring, and both ends of the spring are fixedly connected to the L-shaped plate and the pulling plate respectively.

[0010] The effect achieved by the above components is: improving the stability of the sliding rod and the toothed plate when they are clamped together.

[0011] Preferably, a limiting rod is slidably inserted in the L-shaped plate, a limiting groove is provided on the arc surface of the sliding rod, and the arc surface of the limiting rod is slidably connected to the inner surface of the sliding rod limiting groove.

[0012] The effects achieved by the above components are: achieving the effect of limiting the stretched slide bar, facilitating opening the packaging structure to check the condition of the IPM module, and improving the practicality of the device.

[0013] Preferably, the arc surface of the sliding rod is provided with scale lines.

[0014] The effect achieved by the above components is that it is easy to compare with the pins of the IPM module, so as to determine the depth of the toothed plate's downward movement, thereby improving the practicality of the device.

[0015] Preferably, the size of the tooth opening of the toothed plate is larger than the size of the sliding rod.

[0016] The effects achieved by the above components are: facilitating the sliding rod to be clamped in the toothed plate slot, so that the packaging structure is in a relatively stable state and will not shake under the force of the damper, thereby improving the practicality of the device.

[0017] In summary, the beneficial effects of the present invention are as follows:

[0018] In the utility model, the effect of encapsulating pins of different lengths of the IPM module is achieved, which avoids the situation that when the pins of the IPM module are too long, the pins are placed on the placement board and then the packaging box is sealed, which causes the pins to bend under the pressure of the box cover when the IPM module is placed in the packaging box, thereby improving the practicality of the device.

[0024] Reference Figure 1As shown, the utility model provides a technical solution: a packaging structure of an intelligent IPM module, including a packaging box 1, a fixed plate 2 is fixedly connected to both sides of the packaging box 1, a sliding groove is provided on the surface of the fixed plate 2, a damper 3 is fixedly connected to the inner surface of the sliding groove of the fixed plate 2, a blocking plate 4 is fixedly connected to the surface of the damper 3, a placement plate 5 is slidably connected to the surface of the blocking plate 4, the inner surface of the packaging box 1 is fixedly connected to the support platform 15, the placement plate 5 is slidably connected to the inner surface of the packaging box 1, a clamping groove is provided on the surface of the packaging box 1, a clamping plate 6 is slidably connected to the inner surface of the clamping groove of the packaging box 1, and the clamping plate 6 is fixedly connected to the side away from the packaging box 1. A box cover 7 is connected, and two sliding rods 8 are slidably inserted in the box cover 7. One end of the sliding rod 8 is fixedly connected to a toothed plate 9, and the toothed plate 9 is slidably connected to the inner surface of the fixing groove of the fixing plate 2. The side of the toothed plate 9 away from the sliding rod 8 abuts against the surface of the placement plate 5. The side wall of the fixing plate 2 is fixedly connected with an L-shaped plate 10, and a sliding rod 11 is slidably inserted in the L-shaped plate 10. One end of the sliding rod 11 is fixedly connected to a pulling plate, which achieves the effect of packaging pins of different lengths of the IPM module, and avoids the problem that when the IPM module pins are too long, the IPM module is placed in the packaging box 1 because the IPM module pins need to be placed on the placement plate 5, and then the packaging box 1 is folded. The sealing is carried out, and the pins will be bent under the extrusion of the box cover 7, which improves the practicality of the device. The inner surface of the box cover 7, the surface of the placement plate 5 and the support table 15 are fixedly connected with a protective pad 12. The material of the protective pad 12 is silicone material, which achieves the effect of multi-directional protection of the IPM module and avoids the damage of the IPM module, thereby improving the practicality of the device. The arc surface of the slide rod 11 is sleeved with a spring 13, and the two ends of the spring 13 are respectively fixedly connected to the L-shaped plate 10 and the pull plate, which improves the stability of the slide rod 11 when it is clamped with the toothed plate 9. A limit rod 14 is inserted into the L-shaped plate 10 for sliding. The arc surface of the slide rod 11 A limiting groove is provided, and the arc surface of the limiting rod 14 is slidably connected to the inner surface of the limiting groove of the slide rod 11, thereby achieving the effect of limiting the stretched slide rod 11, facilitating opening the packaging structure to check the condition of the IPM module, and improving the practicality of the device. The arc surface of the slide rod 8 is provided with scale lines, which are convenient for comparison with the pins of the IPM module, so as to determine the depth of the sliding of the toothed plate 9, and improve the practicality of the device. If the size of the tooth mouth of the toothed plate 9 is larger than the size of the slide rod 11, it is convenient for the slide rod 11 to be clamped in the clamping groove of the toothed plate 9, so that the packaging structure is in a relatively stable state and will not shake under the action of the damper 3, thereby improving the practicality of the device.

[0025] Working principle: when the staff needs to package the IPM module, they first observe the length of the IPM module pins, compare the IPM module pins with the scale lines of the sliding rod 8, and then pull the sliding rod 11 to slide in the L-shaped plate 10. The spring 13 is in a stretched state, pushing the limit rod 14 to slide in the L-shaped plate 10 until the limit rod 14 slides into the limit groove of the sliding rod 11. At this time, the sliding rod 8 is pushed to drive the toothed plate 9, the toothed plate 9 drives the placement plate 5, the placement plate 5 drives the blocking plate 4, and the blocking plate 4 drives the damper 3 to be compressed. When the sliding rod 8 drives the toothed plate 9 to slide down to the compared depth, the limit rod 14 is pulled to release the limit rod 14 from the limit of the sliding rod 11, and the sliding rod 11 automatically bounces into the slot of the toothed plate 9 under the action of the spring 13, achieving the effect of fixing the toothed plate 9. After that, the IPM module is placed on the support table 15, and the box cover 7 is closed to seal it. At this time, the effect of packaging the IPM module is achieved.
