Please refer to FIG. 2 to FIG. 5 , wherein FIG. 4 and FIG. 5 are schematic diagrams from different angles of a power module according to a preferred embodiment of the present invention. As shown in the figure, the upper case 21 of the power module 20 of the present invention includes a top plate 211 and a first side plate 212, and the lower case 22 includes a bottom plate 221 and a second side plate 222, wherein the top plate 211 and the bottom plate 221 are disposed opposite to each other, and the first side plate 212 and the second side plate 222 are also disposed opposite to each other. According to the idea of the present invention, the second side plate 222 has a first protruding portion 224 and a second protruding portion 225 compared with the first side plate 212, and the first protruding portion 224 and the second protruding portion The protruding portion 225 is located at two opposite edges of the second side plate 222. The first protruding portion 224 has a first fixing slot 226. The second protruding portion 225 is adjacent to the power transmission interface 26 and has a a second fixing slot 227 .

In addition, as shown in FIG. 2 and FIG. 3 , the upper case 21 also includes an extension plate 214 extending vertically downward from the top plate 211, which can be attached to the second side plate 222 of the lower case 22 and can be locked through the lock.

Engage, and then fix the upper case 21 and the lower case 22 .

Please refer to FIG. 6 , which is a schematic diagram of a power module fixed on a wall of an electronic device body according to a preferred embodiment of the present invention. Since the first protruding portion 224 and the second protruding portion 225 of the second side plate 222 of the power module 20 are respectively provided with a first fixing slot 226 and a second fixing slot 227, the locking components 31, 32 can be used to Correspondingly pass through the first fixing slot 226 and the second fixing slot 227, and lock to the fixing hole (not shown) on the body of the electronic device, so as to fix the power module 20 inside the body of the electronic device. On the wall 30, complete the fixed installation (as shown in Figure 7). In one embodiment, the locking components 31 and 32 can be screws, but not limited thereto.

Since the power module 20 of the present invention is directly attached to the wall surface 30 inside the body of the electronic device with the second side plate 222 of the casing itself, and the first fixing groove on the second side plate 222 is penetrated by the locking components 31 and 32 hole 226 and the second fixing slot 227 for fixing, thus no L-shaped fixing piece or other additional fixing pieces are needed to assist the fixing of the power module 20, so the cost can be saved, and because the power module 20 is directly fixed inside the body of the electronic device The wall 30 of the wall 30 does not need to fix the power module 20 to other fixing parts first, and then fix the fixing parts to the machine body, so the time for installation and fixing is also saved.

On the other hand, although the second side plate 222 has the first protruding portion 224 and the second protruding portion 225 protruding compared to the first side plate 212, but in the design of the first protruding portion 224, the first The protruding part 224 is arranged on the upper end of the first edge of the second side plate 222, and the top plate 211 and the first side plate 212 also have a retracted design at the corresponding position, for example, the first edge of the first side plate 212 The upper end portion has a concave portion 217 (as shown in FIGS. 2 and 3 ), so that the first protruding portion 224 of the second side plate 222 protrudes compared with the concave portion 217 of the first side plate 212, and the second side plate The lower end of the first edge of 222 is still flush with the bottom plate 221 . In other words, the design of the first protruding portion 224 does not increase the volume of the power module 20 .

In the part of the second protruding part 225, the second protruding part 225 is arranged on the second edge of the second side plate 222, that is, the side adjacent to the power transmission interface 26, because the power transmission interface 26 originally protrudes and exposed to the casing of the power module 20, and although the second protruding portion 225 protrudes from the first side plate 21, it does not protrude from the power transmission interface 26, so the second protruding portion 225 The design also does not increase the size of the power module 20 .

Therefore, since the design of the first protruding portion 224 and the second protruding portion 225 does not increase the volume of the power module 20, and the power module 20 is directly fixed on the wall inside the body, it is better than the prior art As far as additional installation space is required for fixing through the L-shaped fixing piece, the design of the power module 20 of the present invention further reduces the installation space required for the power module 20, making the use of space inside the body of the electronic device more efficient, and further enabling Electronic equipment can be developed in the direction of miniaturization.

To sum up, the present invention provides a power module without additional fixing parts, since the second side plate of the casing has a first protruding portion and a second protruding portion compared with the first side plate, and the first The protruding part and the second protruding part respectively have a first fixing slot and a second fixing slot, so that the power module can be directly attached to the wall inside the body of the electronic device with the second side plate of the housing itself, and the lock can be used to The fixing component passes through the first fixing slot hole and the second fixing slot hole on the second side plate for fixing, so no L-shaped fixing piece or other additional fixing pieces are needed to assist the fixing of the power module, so it can be completed quickly and easily The installation has the advantages of saving cost, saving installation time, and reducing the space required for installing the power module. It also makes the use of space inside the body of the electronic device more efficient, and thus enables the development of the electronic device in the direction of miniaturization. Therefore, the present invention has great industrial value, so an application is filed according to law.

The present invention can be modified in various ways by those skilled in the art without departing from the intended protection scope of the appended claims.
