FIG. 1 is a perspective view showing that a panel according to a preferred embodiment of the present invention is mounted on a case. FIG. 2 is an exploded view of the preferred embodiment of the present invention. The present invention discloses a panel structure of a power apparatus. The power apparatus comprises a case 10. The front of the case 10 is longitudinally provided with a panel 20.
The panel 20 is transversely formed with at least two parallel heat dissipation holes 21. The heat dissipation holes 21 are adapted for the case 10 to dissipate heat. The panel 20 is formed with a connecting portion 22 between the heat dissipation holes 21. A heat dissipation net 23 is provided on the heat dissipation holes 21. The heat dissipation net 23 is formed with a plurality of openings 231 corresponding to the connecting portion 22. In this preferred embodiment of the present invention, left and right sides of the panel 20 are formed with a plurality of apertures 24, respectively.
A reinforcement rib 30 is provided and vertically disposed at the inner side of the connecting portion 22. The reinforcement rib 30 is an elongate plate. The reinforcement rib 30 has a long side parallel to a long side of the connecting portion 22. In this preferred embodiment of the present invention, the bottom of the reinforcement rib 30 is formed with a plurality of engaging recesses 31.
At least one fixing plate 40 is provided. The fixing plate 40 is formed with stop pieces 41 extending downward and corresponding in position to the engaging recesses 31. When the fixing plate 40 is engaged with the reinforcement rib 30, the stop pieces 41 are adapted to fix the heat dissipation net 23.
Two L-shaped locking units 50 are provided and disposed at the left and right sides of the panel 20, respectively. The L-shaped locking units 50 each have a first locking piece 51 parallel to the panel 20 and a second locking piece 52 perpendicular to the panel 20. The first locking piece 51 is formed with a plurality of through holes 511 corresponding to the apertures 24. The second locking piece 52 is formed with a plurality of locking holes 521. The through holes 511 and the locking holes 521 are provided with screws 200 respectively for the first locking piece 51 to be locked to the panel 20 and the second locking piece 52 to be locked to the case 10. Furthermore, a retaining piece 512 extends from a middle section of the first locking piece 51. The retaining piece 512 protrudes out of the first locking piece 51. A spacer 53 is provided under the retaining piece 512. A gap is formed between the spacer 53 and the panel 20 for the heat dissipation net 23 to be inserted therein.
A plurality of connecting pieces 60 are provided and vertically disposed at upper and lower sides of the panel 20. The connecting pieces 60 each have a screw hole 61. The screw hole 61 is provided with a screw 200 for the panel 20 to be locked to the case 10.
FIG. 3 is a schematic view of the preferred embodiment of the present invention when in use. FIG. 4 is a sectional view showing the L-shaped locking unit to lock the heat dissipation net according to the preferred embodiment of the present invention. FIG. 5 is a sectional view showing the fixing plate to fix the heat dissipation net according to the preferred embodiment of the present invention. In cooperation with the FIG. 1 and FIG. 2, when the user wants to mount the panel 20 on the case 10, the heat dissipation net 23 is first mounted on the panel 20. The heat dissipation net 23 is placed corresponding in position to the heat dissipation holes 21. The openings 231 of the heat dissipation net 23 is aligned with the connecting portion 22. As shown in FIG. 3, two sides of the heat dissipation net 23 are inserted into the gaps between spacers 53 of the L-shaped locking units 50 and the panel 20. Through the screws 200, the first locking pieces of the L-shaped locking units 50 are locked to the panel 20, so that the two sides of the heat dissipation net 23 are secured. The reinforcement ribs 30 are placed into the openings 231 of the heat dissipation net 23. The fixing plates 40 are connected with the reinforcement ribs 30 respectively, with the stop pieces 41 to engage with the corresponding engaging recesses 31. The fixing plates 40 stride over the openings 231, as shown in FIG. 4, such that the upper and lower sides of the openings 231 of the heat dissipation net 23 are retained. After that, the screws 200 are screwed to the locking holes 521 of the second locking pieces 52 and locked to the left and right sides of the case 10. The screws 200 are screwed to the screw holes 61 of the connecting pieces 60 and locked to the upper and lower sides of the case 10. In this way, the panel 20 is securely fixed to the case 10. When the case 10 is running to generate heat, the heat dissipation holes 21 of the panel 20 are adapted to dissipate heat. The reinforcement ribs 30 provided on the connecting portion 22 is able to reinforce the strength of the connecting portion 22. Thus, the L-shaped locking units 50 and the fixing plates 40 provide a simply way to fix the heat dissipation net 23 so as to enhance the convenience of the heat dissipation net 23. The connecting portion 22 formed between the heat dissipation holes 21 is provided with the reinforcement ribs 30, preventing the panel 20 from collapsing or deforming. The durability of the panel 20 is increased, and the appearance of the panel 20 is pleasing to the eye.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
