Abstract

The utility model relates to an electric vehicle controller. The electric vehicle controller comprises a housing, a pcb and an mos pipe. The mos pipe is installed on one side of the pcb, a pcb slot is formed in one side of the inner wall of the housing, and an mos pipe slot is formed in the other side of the inner wall of the housing. Heat radiating fins are arranged at the position, corresponding to the top surface of the mos pipe slot, outside the housing. An mos pipe fixing device which can fix the mos pipe is movably installed in the mos pipe slot. The mos pipe fixing device is composed of a spring pressing piece and a cylindrical contact pin which is used for fixing the spring pressing piece. A limiting groove and a pin groove are formed in the top of the mos pipe slot, wherein the limiting groove can limit the position of the spring pressing piece 3, and the pin groove can fix the contact pin. Heat radiating aluminum strips are not needed by the controller for heat conduction, and holes do not need to be drilled in the housing, so that the housing is not damaged, and the waterproof and dustproof performance of the controller are improved; the mos pipe directly makes contact with the housing, and therefore the heat radiating effect is enhanced; the damping effect is good, and the mos pipe is not easy to damage.

Embodiment

In the accompanying drawings, this controller for electric vehicle, comprises housing 1, pcb plate 5, mos pipe 4, and described mos pipe 4 is arranged on a side of pcb plate 5; Described housing 1 inwall one side is provided with pcb plate slot 6 along its length, and described housing 1 inwall opposite side is provided with the mos pipe slot 1-3 that can place mos pipe 4 along its length; The end face of the outside corresponding mos pipe slot 1-3 of described housing 1 is provided with fin 1-1; In described mos pipe slot 1-3, be movably installed with the fixedly mos pipe fixing device of mos pipe 4; Described mos pipe fixing device consists of the cylinder type contact pin 2 of spring pressuring plate 3 and fixing spring compressing tablet 3; The top of described mos pipe slot 1-3 is provided with and can limits the stopper slot 1-4 of spring pressuring plate 3 positions and needle tray 1-2 that can fixing plug pin 2.

Described spring pressuring plate 3 comprises and interconnecting and rectangle lamellar body I 3-1 and the lamellar body II 3-3 of angle each other; Wherein, the outer edge of lamellar body II 3-3 is connected with the spacing lamellar body 3-4 of the rectangle of stretching out laterally; The junction of described lamellar body I 3-1 and lamellar body II 3-3 is provided with the arc support rod 3-2 that bottom surface is circular arc; this arc support rod 3-2 can reduce the contact area of spring pressuring plate 3 and mos pipe 4; reduce friction between the two; avoid mos to manage 4 impaired, spring pressuring plate 3 has the effect of heat conduction and damping, mos can be managed to 4 heat and pass to housing 1; strengthen radiating effect; and when controller is collided or vehicle jolts when serious, effective protective circuit plate, alleviates that it is impaired.

Angle between described lamellar body I 3-1 and described lamellar body II 3-3 is 90 degree～175 degree.

Angle between described lamellar body II 3-3 and described spacing lamellar body 3-4 is 90 degree～120 degree.

Described needle tray 1-2 is half-cylindrical, and its slightly larger in diameter, in the diameter of contact pin 2, is located at the inboard of mos pipe slot 1-3 inside top surface; Described stopper slot 1-4 inclination certain angle, is located at the outside of mos pipe slot 1-3 inside top surface, and the bottom of stopper slot 1-4 is positioned at the sidewall of mos pipe slot 1-3, and described stopper slot 1-4 matches with spacing lamellar body 3-4.

Use under shape, when spring pressuring plate 3 lies in mos, manage 4 end faces, when lamellar body I 3-1 is level, the height of spring pressuring plate 3 is not less than the end face of mos pipe 4 and the distance between mos pipe slot 1-3 end face; The radius of described contact pin 2 is not less than the end face of lamellar body I 3-1 and the distance between mos pipe slot 1-3 end face.

During use, pcb plate 5 is inserted by one end of housing 1 together with mos pipe 4, thereby mos pipe 4 is flat in mos pipe slot 1-3; And then the spacing lamellar body 3-4 of spring pressuring plate 3 is aimed to stopper slot 1-4, and spring pressuring plate 3 is pushed in mos pipe slot 1-3, now spring pressuring plate 3 is placed in mos and manages 4 tops, and arc support rod 3-2 manages 4 end faces with mos and touches and support mutually; Again contact pin 2 is pushed in needle tray 1-2, make contact pin 2 prop up lamellar body I 3-1 downwards, thereby reach the fixedly object of mos pipe 4.Meanwhile, spring pressuring plate 3 and contact pin 2 play the effect of heat conduction, have strengthened the radiating effect of mos pipe 4.

By finding out above, controller described in the utility model, abandoned the mode that traditional utilization heat radiation aluminum strip is 4 heat radiations of mos pipe, thereby avoided being screwed because of needs the way that heat radiation aluminum strip punches on the housing 1 of controller, not only make the better tightness of controller housing 1, and greatly improved the heat dispersion of mos pipe 4, there is good promotion prospect.
