Description
Technical field
The utility model belongs to a kind of equipment of electric automobiles, is a kind of electric motor car control appliance more specifically.
Background technology
At present, motor vehicle comprises electric bicycle, electro-tricycle, battery-operated motor cycle etc., and controller need have good waterproof, heat radiation, shockproof properties as the control maincenter part of electric motor car.If radiating effect is bad, the circuit board long-term work, temperature raise to surpass the peak of components and parts, and components and parts damage, thereby cause controller work undesired and even operate malfunctioning; If poor sealing, the electric vehicle controller water inlet makes the components and parts short circuit of circuit board malfunctioning.
Common controller on the market, be when the constant power pipe, to adopt to punch in the housing side, and with screw with the fixing this mode in the side of power tube and housing, the defective that can bring screw hole to leak like this, thus cause electric vehicle controller to damage, need and twist screw in the punching of housing side simultaneously, so complex procedures, be unfavorable for enhancing productivity, also bring very big puzzlement, dismounting complexity for maintenance.
Controller architecture on the market is that shell is divided into loam cake and drain pan two parts, these two parts connect by the buckle spiral-lock, because the buckle place leaves the space, steam is easy to enter in the cavity at circuit board place by this space, makes the components and parts short circuit of circuit board malfunctioning; Even smear one deck waterproof material at the buckle place, because the limitation of waterproof material water resistance is added when smearing, be subjected to the influence of operating personnel's level, coating layer thickness is inhomogeneous, influences sealing effectiveness; Because the thermal conductivity of waterproof coating is bad, between loam cake and drain pan, reduced the effect of heat radiation simultaneously, made loam cake and drain pan can not form the radiator of a circulation.
In a word, this side punching of electric vehicle controller of the prior art and to twist the waterproof effect of monolithic construction of screw bad, the effect that the structure of loam cake and drain pan spiral-lock combination can not well reach not only waterproof but also dispel the heat, and these waterproof cooling problems all are the more scabrous technical problems of present electric vehicle controller technical field.
The shortcoming of existing controller is:
1. the consistency of installing owing to power tube can not guarantee, thereby power tube can not closely be contacted with loam cake, and the heat of power tube just can not pass by loam cake preferably, thereby can not reach better radiating effect.
2. power tube is screwed on the shell of controller, need make a call to 3 holes at least in the side of shell, earlier power tube is connected on the aluminum strip with screw, on aluminum strip, punch again, match in the hole of this hole and shell side, pass the hole of aluminum strip and shell side at last with screw, the three is coupled together.
3. the housing side has screw hole also can bring the defective of leaking, and causes controller malfunctioning, brings potential safety hazard to electric motor car.
4. shell is made of loam cake and drain pan two parts, and the space is left in the junction, causes poor sealing, water inlet easily, and waterproof effect is poor.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of water proofing property, good seal performance, installation are firm, easy accessibility, easy to maintenance and help the electric vehicle controller of power tube heat radiation.
The technical problem that the utility model solves takes following technical scheme to realize: a kind of electric vehicle controller, comprise shell, circuit board and the end cap that is arranged on the shell two ends, described shell is all-in-one-piece cavity structure, the top of described shell inner cavity is provided with the protrusion of downward protrusion, power tube on the described circuit board is arranged between the sidewall of described protrusion and described shell, also be provided with springs between described power tube and the described protrusion, described springs is used to compress described power tube, the middle part of described springs is provided with bent sheet, the lower end of described protrusion is provided with saddle, be used to hold the bent sheet of described springs, the top of described shell inner cavity also is provided with groove, and described groove is used to place the upper end of described springs.
The technical problem that the utility model solves can also take following technical scheme to realize: the section configuration of described springs is roughly " fore-telling " shape, and its top is provided with a bend, and is positioned in the described groove; Described shell inner cavity surface is smooth circular arc with the coupling part of described groove, and the center of circle of circular arc is below circular arc, and the central angle of circular arc is less than or equal to 90 degree; The bottom of described springs is provided with kink, is used for extruding, constant power pipe; The side of described springs is provided with guide plate, and guide plate is partial to described saddle one side; Described saddle and protrusion are tabular; The sidewall of described shell is provided with the limiting stand that is used for the described power tube of maintenance; Described bent sheet be equidistant intervals be arranged on described springs in a lateral direction; The kink of described shell fragment shape spring is provided with the breach of vertical direction, makes kink form several free ends; Described free-ended number is a times or two times of circuit board power tube number preferably.
The utility model compared with prior art has significant advantage and beneficial effect, is embodied in the following aspects:
1. the active force of springs generation can make power tube contact more closely with shell, has increased area of dissipation, and has improved the steadiness of power tube, and shockproof properties is good.
2. only need to be provided with the springs of kink shape, both can reach good waterproof effect, saved production cost again, and improved production efficiency with simple bottom; Simultaneously, operation is few, and is very simple during dismounting, helps maintenance.
3. because the stroke of springs is bigger, not only tighten effectively, and lower to the required precision of shell processing, help reducing cost and enhancing productivity.
4. shell adopts the integral type cavity structure, and the infiltration in gap had both been avoided in the gap when having avoided spiral-lock to connect, and has guaranteed the good result of circulation heat radiation again.
