The bottom case 20 includes a bottom wall 21 and a side wall 22 connected to the bottom wall 21, and the bottom wall 21 and the side wall 22 enclose a cavity formed with a plurality of module limiting slots 201 for placing power modules. The side of the upper cover 30, which is covered with the bottom case 20, is provided with a pressing block 301 corresponding to the module limiting groove 201, and the side of the upper cover 30, which is away from the bottom case 20, is provided with a stacking buffer pad 311 for protecting the package box 100. The structure design of the module limiting groove 201 can play a role in preliminary limiting on the power module, the design of the pressing block 301 can play a role in positioning the power module, and further, the pressing block 301 adopts an overpressure design, so that even if the packaging box 100 is pressed and deformed in the transportation process, the pressing block 301 can fix a product, and therefore effective protection of the power module can be ensured; in summary, through the mutual cooperation of the module limiting groove 201 on the bottom box 20 and the pressing block 301 arranged on the upper cover 30, the power module can be effectively prevented from shifting and being extruded by the package box 100 body; in the transportation or storage application scenario, when a plurality of packaging boxes 100 are stacked, the stacking buffer cushion 311 is disposed on one side of the upper cover 30 away from the bottom box 20, so that the packaging boxes 100 and/or the power modules can be effectively prevented from being damaged due to mutual extrusion or friction between the packaging boxes 100, and the packaging boxes 100 and/or the power modules can be better protected.

In a preferred embodiment, as shown in fig. 2 and 4, the reinforcing ribs 202 corresponding to the respective module limiting grooves 201 and the notches 2020 formed in the reinforcing ribs 202 are formed on the bottom case 20 in a protruding manner from the bottom wall 21 portion in the transverse direction of the arrangement of the module limiting grooves 201, and the supporting blocks 302 are provided on the upper cover 30 at positions corresponding to the notches 2020. The design of the slot 2020 may be used as an accommodating space for the support block 302, which is helpful for the accurate matching of the stiffener 202 and the support block 302; preferably, the first contact cambered surface 2021 is further arranged on the reinforcing rib 202, the second contact cambered surface 3022 corresponding to the first contact cambered surface 2021 is arranged on the supporting block 302, and the structural design ensures that in the covering process of the bottom box 20 and the upper cover 30, the clamping process of the reinforcing rib 202 and the supporting block 302 is smooth and unobstructed under the action of the first contact cambered surface 2021 and the second contact cambered surface 3022, so that possible collision and scratch in the multiple use process are effectively avoided, and the abrasion process of the packaging box 100 is relieved; preferably, the reinforcing ribs 202 are distributed at the middle position of the bottom wall 21, and the position is selected so as to effectively avoid the problem that the middle part of the upper cover 30 is recessed when a plurality of packaging boxes 100 are stacked; according to the scheme, the reinforcing ribs 202 are matched with the supporting blocks 302, so that supporting force can be provided for the packaging box 100, the strength and the bearing capacity of the packaging box 100 are effectively improved, and the packaging box 100 is prevented from deforming in the carrying process. More preferably, reinforcing ribs 202 may be added around the bottom case 20 to enhance the supporting force of the edges of the package 100.

In a preferred embodiment, as shown in fig. 2, buffer pads 2011 are disposed on two opposite side walls of each module limiting slot 201. The metal heat dissipation bottom plate of the power module plays a role in heat dissipation in the working process of the module, a layer of electroplated layer is arranged on the surface of the metal heat dissipation bottom plate to protect the metal surface, and if deformation occurs in the transportation process, the surface of the metal heat dissipation bottom plate is scratched, so that the performance of a product is degraded. The design of the cushion 2011 not only can prevent the metal radiating bottom plate of the power module from being scratched, but also can play a role in flexible positioning through contact with the metal radiating bottom plate.

In a preferred embodiment, as shown in fig. 2, slots 2012 for taking and placing the power modules are provided on two opposite side walls of each module limiting slot 201, and the slots 2012 are located on two different sides from the buffer pads 2011. For example, the cushion pad 2011 is provided in the lateral direction of the arrangement of the module limit grooves 201, and the slit 2012 is provided in the longitudinal direction of the arrangement of the module limit grooves 201. The design of the slot 2012 can facilitate the taking and placing of the power module, and the possible abrasion and scratch to the power module in the taking process are effectively avoided.

In a preferred embodiment, as shown in fig. 2 and 4, the upper cover 30 is further provided with a stopper 306 corresponding to the module limiting groove 201, and the stopper 306 is provided with a clearance groove 3061. The design of the limiting block 306 and the avoidance groove 3061 can effectively prevent the upper cover 30 from deforming when being partially pressed, and the upper cover 30 is sunk and touches the signal Pin needle; preferably, the depth of the clearance groove 3061 is greater than the length of the Pin, so as to ensure that the signal Pin is not touched when the upper cover 30 reaches the sinking limit, and the signal Pin is not contacted by external force or foreign objects. Because the briquetting 301 presses the angles on 4 edges of the power module, the power module is large in size, and for the protection of the middle part of the power module, the limiting block 306 is mainly used for limiting the power module when the box body in the middle part of the module is extruded and deformed, so that the limiting block 306 can limit the power module and prevent the box body from being pressed to the Pin needle.

The design of the orientation recognition notch 23 facilitates positioning of the bottom case 20 and the upper cover 30 during assembly. Preferably, the direction recognition notch 23 is provided at one corner of the package 100.

In a preferred embodiment, the press block 301 includes a contact portion 3011 and a root portion 3012 connecting the contact portion 3011, the volume of the contact portion 3011 being smaller than the volume of the root portion 3012. The contact part 3011 with smaller volume is easy to be pressed and deformed when contacting a product, can provide flexible pressure with buffer for the power module, and the root 3012 with larger volume can provide certain strength so as not to cause the pressing block 301 to lose pressure after being pressed and deformed; preferably, the contact 3011 is disposed at a corner of the root 3012 facing the power module, and the contact 3011 is configured to be positioned closest to and against the power module.
