Description

A kind of controller for electric vehicle heat-dissipating casing

Technical field

The utility model relates to a kind of casing of electric vehicle controller, and a kind of controller for electric vehicle heat-dissipating casing, belongs to controller for electric vehicle technical field specifically.

Background technology

At present, controller for electric vehicle is the central control unit of electric motor car, and due to its long-term work, its components and parts self-heating, if do not have good heat radiation, easily damages because temperature is too high; In addition due to the work bad border of its open air, the water-tight of himself also has requirement.Most controller assembling is in the market all adopt power component (power tube) to be screwed on aluminum strip, puts a slice dielectric film and prevent its electric leakage to shell between power tube and aluminum strip.Then aluminum strip tension is touched shell heat radiation by the hole of the side of shell by screw.

There is shortcoming and be in existing controller housing scheme: (1), due to the very difficult guarantee of consistency of manual assembly when a lot of power tubes is assembled on aluminum strip, the heat of power tube just can not well be gone over by radiation shell transmission; (2) because fixed screw when being assembled to aluminum strip at power tube perforates a hole to be screwed on aluminum strip again on dielectric film, easily dielectric film torn when perforation and cause electric leakage; (3) all power tubes will be screwed on aluminum strip one by one in assembling process, then aluminum strip will have the screw of more than 3 to be fixed on shell again, a lot of artificial of whole process need, and efficiency is very low; (4) shell side draws the screw hole of aluminum strip to be a leak of controller waterproof, and the water capacity is easily entered from its infiltration.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thus provides a kind of controller for electric vehicle heat-dissipating casing, can install simple, firm by guaranteed output pipe, improve radiating shell water resistance, improve the heat dispersion of casing of electric vehicle controller.

According to the technical scheme that the utility model provides, a kind of controller for electric vehicle heat-dissipating casing comprises 7 font shell fragments, wiring board, power tube and shell, shell inner cavity bottom is provided with wiring board draw-in groove, wiring board is clamped in wiring board draw-in groove, bonding power pipe on wiring board, it is characterized in that: the shell fragment that described shell inner cavity top is provided with shell fragment draw-in groove and protrusion compresses lug boss, shell fragment compresses boss in shell fragment draw-in groove opening part; Be provided with 7 font shell fragments between shell fragment draw-in groove and power tube, described 7 font shell fragments comprise shell fragment and lower shell fragment, and upper shell fragment and lower shell fragment are linked into an integrated entity by shell fragment knuckle; Upper shell fragment stretches in shell fragment draw-in groove, and upper shell fragment lower surface compresses lug boss difference corresponding compress with shell fragment with shell fragment draw-in groove lower surface, rear portion, upper shell fragment upper surface contact with shell fragment draw-in groove upper surface, shell fragment knuckle; Lower shell fragment lower end compresses contact power tube, is pressed on the sidewall of shell inner cavity by power tube.

Further, shell is the cavity type aluminum hull of integrally stretching.

Further, lower shell fragment lower end is provided with the lower shell fragment lug boss of U-shaped.

Further, lower shell fragment lower end is provided with multiple separation trough, and multiple separation trough is uniformly distributed along lower shell fragment length direction.

Compared with the prior art the utility model has the following advantages:

The utility model structure is simple, compact, reasonable, can ensure that multiple power tube installation site is consistent, and power tube is installed simple, firm, improves efficiency of assembling; Owing to not needing screw to pass dielectric film, do not have when screw screws in and tear dielectric film, cause the problem of leaking electricity; Radiation aluminium shell-side face does not have hole, and water resistance is better.

Fig. 2 is 7 font shell fragment front views.

Description of reference numerals: under 1-7 font shell fragment, 2-wiring board, 3-power tube, 4-shell, 5-wiring board draw-in groove, 6-shell fragment draw-in groove, the upper shell fragment of 7-, 8-, under shell fragment, 9-shell fragment knuckle, 10-separation trough, 11-, shell fragment lug boss, 12-shell fragment compress lug boss.

Embodiment

Embodiment in is by reference to the accompanying drawings further described by the utility model below:

As shown in Figure 1 and 2, the utility model mainly comprises 7 font shell fragments 1, wiring board 2, power tube 3 and shell 4, and shell 4 inner chamber bottom is provided with wiring board draw-in groove 5, clamps wiring board 2 in wiring board draw-in groove 5, bonding power pipe 3 on wiring board 2.

Described shell 4 is the cavity type aluminum hull of integrally stretching, the shell fragment compression lug boss 12 that shell 4 inner chamber top is provided with shell fragment draw-in groove 6 and protrudes, and shell fragment compresses lug boss 12 and is positioned at shell fragment draw-in groove 6 opening part.

7 font shell fragments 1 are provided with between shell fragment draw-in groove 6 and power tube 3.As shown in Figure 2, described 7 font shell fragments 1 comprise shell fragment 7 and lower shell fragment 8, and upper shell fragment 7 and lower shell fragment 8 are linked into an integrated entity by shell fragment knuckle 9.Upper shell fragment 7 stretches in shell fragment draw-in groove 6, and upper shell fragment 7 lower surface compresses lug boss 12 difference corresponding compress with shell fragment with shell fragment draw-in groove 6 lower surface, rear portion, upper shell fragment 7 upper surface contact with shell fragment draw-in groove 6 upper surface, shell fragment knuckle 9.

Lower shell fragment 8 lower end compresses contact power tube 3, is pressed on by power tube 3 on the sidewall of shell 4 inner chamber.

Described lower shell fragment 8 lower end is provided with the lower shell fragment lug boss 11 of U-shaped, and lower shell fragment lug boss 11 can better contact with power tube 3, thus compresses power tube.

Described lower shell fragment 8 lower end is provided with multiple separation trough 10, and multiple separation trough 10 is uniformly distributed along lower shell fragment 8 length direction.

The utility model is when assembling, first the wiring board welding power tube is loaded in the wiring board draw-in groove of shell inner cavity, the upper shell fragment of 7 font shell fragments is snapped in shell fragment draw-in groove, then exert a force to the right at shell fragment knuckle place, shell fragment knuckle is extruded onto shell fragment to compress on the right side of lug boss 12, now power tube is pressed on the sidewall of shell inner cavity by the lower shell fragment of 7 font shell fragments.The utility model structure is simple, compact, reasonable, can ensure that multiple power tube installation site is consistent, and power tube is installed simple, firm, improves efficiency of assembling; Owing to not needing screw to pass dielectric film, do not have when screw screws in and tear dielectric film, cause the problem of leaking electricity; Radiation aluminium shell-side face does not have hole, and water resistance is better.
