AI Technical Summary
Existing controller housings for electric medical beds face challenges in achieving both sealing and effective heat dissipation, as the sealing mechanism often leads to a closed environment that impedes heat dissipation and causes adhesion issues with the sealing ring over time.
A controller housing design featuring heat dissipation grooves, heat conducting plates, and ventilation holes, along with a detachable sealing ring placement between heat conducting plates, facilitates heat dissipation through heat dissipation pins and allows easy removal of the sealing ring.
The design ensures effective heat dissipation while preventing the sealing ring from adhering to the housing, enhancing disassembly and improving thermal management through enhanced air flow and conductive heat transfer.

[0003] The controller housing for electric medical beds usually has a sealing ring between the upper and lower shells to achieve IP65 and IP66 protection levels to meet the needs of different customers and usage scenarios. However, this method will cause a closed environment to be formed inside the controller housing, which is not conducive to heat dissipation of internal components during operation. In addition, long-term use of the sealing ring will cause the sealing ring to adhere to the upper and lower shells of the controller, affecting the disassembly of the controller housing.

The upper heat conducting plate can be detachably connected to the mating surface of the platform, and the lower heat conducting plate can be detachably connected to the mating surface of the lower boss and the upper boss. A plurality of heat dissipation pins are respectively connected to the upper heat conducting plate and the lower heat conducting plate, and the heat dissipation pins of the upper heat conducting plate extend into the heat dissipation groove and the upper shell respectively, and the heat dissipation pins of the lower heat conducting plate extend into the heat dissipation groove and the lower shell. An arched protrusion matching the sealing groove formed on the mating surface of the lower boss is formed on the lower heat conducting plate, and a sealing ring for sealing is embedded in the arched protrusion of the lower heat conducting plate.
[0006] A further improvement includes that the heat dissipation slot adopts a through structure so that the heat dissipation slot is connected to the outside.
[0007] A further improvement includes providing ventilation holes on the upper shell and the lower shell respectively, wherein the ventilation holes are connected to the heat dissipation grooves.
[0008] A further improvement includes connecting a guide column to the fitting surface of the upper boss, and the guide column passes through the upper heat conducting plate and the lower heat conducting plate in sequence, and the guide column is embedded in a positioning hole opened on the fitting surface of the lower boss.
[0009] The beneficial effects of the utility model are as follows: the design facilitates the disassembly of the sealing ring by arranging the sealing ring between the upper heat conducting plate and the lower heat conducting plate, thereby avoiding adhesion of the sealing ring to the controller housing; the upper heat conducting plate and the lower heat conducting plate conduct heat through the heat dissipation pins; the vents can increase the air flow in the heat dissipation slot and improve the heat dissipation effect of the heat dissipation pins; the guide columns and the positioning holes play a role of docking and limiting.

Into the heat dissipation groove 5 and the upper shell 1, the heat dissipation pin 13 of the lower heat conducting plate 7 extends into the heat dissipation groove 5 and the lower shell 2, so that the heat generated in the controller is discharged through the heat dissipation pin 13, the upper heat conducting plate 10 and the lower heat conducting plate 7, and an arched protrusion is formed on the lower heat conducting plate 7 to match the sealing groove 8 opened on the fitting surface of the lower boss 4, and a sealing ring 6 for sealing is embedded in the arched protrusion of the lower heat conducting plate 7.
