Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.
[0019] As Figure 1 、 2 shown, an inverter housing of a lightweight electric drive system includes a shell cover 1. A rib 4 is provided on the inner surface of the shell cover 1, a reticulation 2 is provided on the edge surface of the shell cover 1, and a heat dissipation and dust-proof assembly 5 is provided on the surface of the shell cover 1.
[0020] As Figure 1As shown, a number of mounting holes 3 are fixedly installed at equal distances on the four sides of the upper surface of the shell cover 1, facilitating the installation of the shell cover 1 by this device.
[0021] As Figure 2 , 3 shown, the rib 4 is in a honeycomb shape. The use of a honeycomb-shaped rib provides better anti-collision performance and a more solid structure. The heat dissipation and dust-proof component 5 includes a number of heat dissipation holes 501. A number of the heat dissipation holes 501 are equidistantly arranged on the inner surface of the shell cover 1. An installation sleeve 503 is installed inside the heat dissipation hole 501. An internal thread 502 is provided on the inner wall of the heat dissipation hole 501. An external thread 504 is provided on the side of the installation sleeve 503. The external thread 504 is meshed and connected with the internal thread 502. A dust-proof net 505 is fixedly installed between the inner walls of the installation sleeve 503. An installation column 506 is fixedly installed on the upper surface inside the dust-proof net 505. A texture 2 is provided on the edge surface of the shell cover 1, which can provide better sealing performance when installing the shell cover 1. The shell cover 1 is made of an aluminum casting, and the aluminum material is injection-molded. The aluminum material has better heat dissipation and exhaust performance. The use of a honeycomb-shaped rib provides better anti-collision performance and a more solid structure. By providing the heat dissipation holes 501, the heat dissipation efficiency of this device can be better. By providing the dust-proof net 505, it can play a role in dust-proofing the heat dissipation holes 501, preventing dust from entering the device interior through the heat dissipation holes 501 and affecting the operation inside the inverter. When it is necessary to clean the dust-proof net 505, by the staff rotating 506, the installation sleeve 503 can be rotated at the same time, so that the installation sleeve 503 rotates inside the heat dissipation hole 501, and the external thread 504 is disengaged from the internal thread 502. At this time, the installation sleeve 503 can be disengaged from the heat dissipation hole 501, and at this time, the dust-proof net 505 can be disengaged from the heat dissipation hole 501, facilitating the staff to clean and replace the dust-proof net 505. Conversely, the dust-proof net 505 can be installed, facilitating the operation of the staff.
[0022] The working principle of this lightweight electric drive system inverter housing:
[0023] In use, a reticulation 2 is provided on the edge surface of the shell cover 1, which can provide better sealing performance when installing the shell cover 1. The shell cover 1 is made of an aluminum casting, and the aluminum material is injection-molded. The aluminum material has better heat dissipation and exhaust performance. The honeycomb-shaped convex ribs provide better anti-collision performance and a more solid structure. By providing heat dissipation holes 501, the heat dissipation efficiency of this device can be improved. By providing a dust-proof net 505, it can prevent dust from entering the device through the heat dissipation holes 501 and affecting the internal operation of the inverter. When the dust-proof net 505 needs to be cleaned, by the staff rotating 506, the mounting sleeve 503 can be rotated simultaneously, causing the mounting sleeve 503 to rotate inside the heat dissipation hole 501, disconnecting the external thread 504 from the internal thread 502. At this time, the mounting sleeve 503 can be detached from the heat dissipation hole 501, and then the dust-proof net 505 can be detached from the heat dissipation hole 501, facilitating the staff to clean and replace the dust-proof net 505. Conversely, the dust-proof net 505 can be installed, making it convenient for the staff to operate.
