Abstract

A structure for mounting electronic apparatuses in an electric motor-driven vehicle can be provided, in which the electronic apparatuses such as a high voltage battery unit and motor control unit can be mounted compactly in the same section occupying a minimum mounting space, allowing them to be mounted in a vehicle of rather short wheelbase, driving efficiency of the electric motor can be improved by reducing the length of cables for transferring high voltage electric power, and space for mounting the refrigerating system can be increased which eases the mounting of the refrigerating system. The structure comprises: a pair of first brackets each having a base part being fixed to the side face of a chassis frame extending in the longitudinal direction of the vehicle and an arm part extending in the lateral direction of the vehicle, a pair of second brackets fixed to the upper surfaces of said arm parts such that they extend in the longitudinal direction of the vehicle with a certain space between them, said battery unit placed on the upper surfaces of said second brackets, and said electronic apparatus unit is placed under said battery unit between said second brackets.

Claims

1. A structure for mounting electronic apparatuses to a vehicle in an electric motor-driven vehicle (50) having an electric apparatus unit (2) for controlling an electric motor (61) to drive wheels (53) and a battery unit constituting electric source for them, comprising:

a pair of first brackets (10) each having a base part (12z) to be fixed to the side face of a chassis frame (54) extending in the longitudinal direction of the vehicle (50) and an arm part (12y) extending in the lateral direction of the vehicle (50), and a pair of said first brackets being provided with a certain distance length to each other in the longitudinal direction of the vehicle,

a pair of second brackets (20) fixed to the upper surfaces of said arm parts (12y) such that the second brackets extend in the longitudinal direction of the vehicle with a certain space between them,

said battery unit (1) placed on the upper surfaces of said second brackets (20), and

said electronic apparatus unit (2) located under said battery unit (1) between said second brackets (20).

2. The structure for mounting electronic apparatuses to a vehicle according to claim 1, wherein the height (H) of each of said second brackets (20) is higher than the height (H1) of said electronic apparatus unit (2).

3. The structure for mounting electronic apparatuses to a vehicle according to claim 1, wherein a bracket means (30) comprised of said first brackets (10) and second brackets (20) is attached to the chassis frame (54) of the vehicle (50) between front and rear wheels.

4. The structure for mounting electronic apparatuses to a vehicle according to claim 1, wherein an accessory (59) is attached to said chassis frame (54) between a front wheel (52) of the vehicle (50) and a bracket means (30) comprised of said first brackets (10) and second brackets (20).

5. The structure for mounting electronic apparatuses in a vehicle according to claim 1, wherein each of said second brackets (20) has a vertical wall part, a lower flange extending from the lower end of said vertical wall part to be attached to the upper surfaces of the arm parts (12y) of said first brackets (10), and an upper flange extending from the upper end of said vertical wall part on which said battery unit (1) is placed, and wherein said electronic apparatus unit (2) is fixed to the vertical wall parts of said second brackets (20).
