Abstract
Disclosed herein is an assembly structure for a motor drive unit. An assembly structure for a motor drive unit is disclosed. The assembly structure does not require the time for rotating, laying down, or fastening the components during processes of producing it, so that the time required for production can be shortened. In addition, since no separate fastening part is required, the assembly structure can be simplified and the production costs can be reduced.
Claims8
An assembly structure for a motor drive unit for converting an input power into an alternating current (AC) power suitable for driving a motor, including:
- a base case;
- a heat dissipation fan comprising a fan and a fan housing arranged outside the fan to fix the fan, the heat dissipation fan being disposed in an area of an upper portion of the base case;
- a heat sink comprising a base and at least one side face portion formed by extending vertically downward from both left and right ends of the base, the heat sink being disposed on one side of the heat dissipation fan on the base case;
- a middle base disposed on the heat sink;
- a power printed circuit board (PCB) assembly disposed on the middle base;
- and
- a filter PCB assembly disposed over the power PCB assembly, the assembly structure comprising:
- at least one hook fixing portion disposed on an upper surface of the base case to face a front face portion of the fan housing;
- at least one hook support disposed on the upper surface of the base case to face a rear face portion of the fan housing;
- a first guide portion disposed on the upper surface of the base case to face each of a left side face portion and a right side face portion of the fan housing;
- and
- a hook engagement portion formed on an inner surface of each of the at least one hook fixing portion and the at least one hook support facing each other across the fan housing,
- wherein a hole fitting with the hook engagement portion is formed in areas facing the hook engagement portion on a front surface and a rear surface of the fan housing,
- wherein at least one first hook portion is disposed on the upper surface of the base case to fix the heat sink at the at least one side face portion of the heat sink,
- wherein a second guide portion is disposed on the upper surface of the base case along the at least one side face portion of the heat sink except for an area where the at least one first hook portion is disposed,
- wherein a rib vertically protruding from an area of the base case is provided facing a lower surface of the at least one side face portion of the heat sink, and
- wherein the lower surface of the at least one side face portion of the heat sink is provided with a recess in which the rib enters.
