Abstract
The utility model relates to the brush motor controller of an electric vehicle, comprising a housing, an upper cover, a control circuit board, and a port flat pencil. Epoxy resin is enclosed inside the housing, constituting a modularized whole structure. The modularized structure enclosed by the epoxy resin completely seals and insulates the chips of the circuit board, the components and the housing, having three prevention traits of waterproof, shakeproof and antisepsis. When the electric vehicle runs in rainy days or is washed, water cannot get into the controller from the aperture of the housing, causing no circuit damage or component corrosion. The flat pencil is led out from the two sides, and the line port adopts the standardized connector. The brush motor controller of an electric vehicle of the utility model has easy mount and commissioning, reliable running of the whole vehicle, long life time, and firm reliability, and can meet the requirements of electric vehicle manufacturing enterprises.
Description
Technical field
The utility model relates to a kind of electric machine controller, particularly a kind of electric motor car brush motor controller.
Background technology
At present, the brush motor controller architecture that the electric motor car industry is adopted is generally control circuit is installed in metal or the plastic casing, circuit board and components and parts and shell have certain space, shell can not guarantee to seal fully, electric motor car travels on the road that jolts for a long time, can make controller part occur becoming flexible, coming off; Electric motor car also can make water enter controller inside from the shell slit when the rainy day travels or wash and cause circuit damage or component corrosion, thereby shortened its useful life.
Summary of the invention
In view of the prior art above shortcomings, the utility model provides a kind of modular construction, built-in electrical insulation encapsulation and draws the electric motor car brush motor controller of novel shockproof, the anti-liquid infiltration of port wire harness from bilateral.
The technical scheme that the utility model is taked for achieving the above object is: controller comprises casing, loam cake, control circuit board and terminal wire harness, it is characterized in that in the inner encapsulating epoxy resin of casing, composition module overall structure.
Because the modular construction that adopts epoxy encapsulation is gone up in the utility model design, with the chip of wiring board and components and parts with the complete sealed insulation of casing, have waterproof, shockproof and corrosion-resistant three anti-characteristics, bilateral is drawn wire harness, line port adopts standardized connector, be easy to Installation and Debugging, make car load reliable, the life-span is long, more solid and reliable.
Description of drawings
Fig. 1 is the utility model structure cutaway view, and book extract accompanying drawing as an illustration;
Fig. 2 electric motor car brush motor controller logic block diagram.
1. shells among the figure, 2. loam cake, 3. base plate, 4 wiring boards, 5. components and parts, 6 screws, 7 wire harness, 8. epoxy resin.
Embodiment
As shown in Figure 1, electric motor car brush motor controller is placed on shell (1) the right and left by the wiring board that will weld components and parts (5), its cross section is the interior edge (11) of h shape, (12) on the plane, and with screw (6) with wiring board (4), plastic shell (1) is fixing with the base plate (3) of aluminum material, encapsulated epoxy resin (8) in the enclosure, make the complete submergence of components and parts (5) and wiring board (4) and be solidified into module with epoxy resin (8), port wire harness (7) is drawn at shell (1) loam cake (2) both-side opening suitable for reading from gland, line port adopts standardized connector, and loam cake (2) cements with binder with shell (1) junction
The circuit structure of electric motor car brush motor controller is made of single-chip microcomputer and peripheral circuit as shown in Figure 2, realizes the real-time change at random of power-assisted state by the program that writes chip.
After CPU handles, give the shaping amplification driving circuit, export from the command signal of handle, brake lever through carrying out terminating circuit MOS, again through current limliting, overcurrent protection, detection, amplifying circuit output control signal, this control signal one tunnel is passed to brush motor, and another road feeds back to singlechip CPU;
Single-chip microcomputer sends riding speed and the storage battery electric quantity signal that feeds back to Displaying Meter simultaneously;
From the rotary speed information that is installed in the Hall element on the foot-operated axis of electric motor car, after CPU handles, the controller output order, the rotating speed of brush motor output is changed according to foot-operated varying in size of power, power-assisted and electronic ratio are: 1: 1,1: 2,1: 3, the change of its power-assisted ratio was to trigger by the knob on the handgrip.
With the change of the rotational angle of electric motor car handgrip, the voltage signal of the Hall element output on the handgrip also changes thereupon, and after CPU handled, the controller output order made the rotating speed of brush motor output vary in size according to the handgrip rotational angle and changes.
When the rotation of electric motor car handgrip paused 8 seconds in a certain position, receive the information of Hall element output, after CPU handles, the controller output order, making the rotating speed of brush motor output is definite value.
It is known that the principle of electric motor car brush motor controller and circuit are the present technique field, is appreciated that and reproduces by the present technique domain knowledge.
Make as stated above, can constitute the electric motor car brush motor controller with modular construction of present embodiment.
Claims (2)
1. electric motor car brush motor controller comprises shell (1), loam cake (2), the wiring board (4) and the port wire harness (7) of components and parts (5) have been welded, it is characterized in that encapsulated epoxy resin (8) in shell (1), make the complete submergence of components and parts (5) and wiring board (4) and be solidified into module with epoxy resin (8), port wire harness (7) is drawn at shell (1) loam cake (2) opening suitable for reading from gland, loam cake (2) cements with binder with shell (1) junction, the composition module overall structure
2. device according to claim 1 is characterized in that port wire harness (7) slave controller bilateral draws.
