Description
Technical field：
The utility model is related to the control box field of electric bus, specifically a kind of anti-water control for electric bus
Box processed.
Background technology：
Circuit board is housed in the control box on electric bus, is the vital part of whole vehicle, due to current control box
It is unreasonable in structure design so that poor sealing, since electric bus is constantly in working condition, circuit board be easy by
Tide, aging and damage.
Utility model content：
The purpose of this utility model provides a kind of reasonable in design, good airproof performance exactly in order to solve existing issue,
Can also in control box pressure the waterproof control box for electric bus.
The technology solution of the utility model is as follows：
A kind of waterproof control box for electric bus, including pedestal and the upper cover for being bolted in base top surface, the bottom
Seat is rectangular, and inside forms the chamber for accommodating circuit board, and the chamber bottom is equipped with several guide posts and threaded post, institute
It states and forms several connection jaws on the long side wall side of pedestal, semi-enclosed seal groove is molded on the top surface of the pedestal, it is described
Upper cover top surface forms several heat dissipation raised lines, and the lower end of the heat dissipation raised line is equipped with the installation screw for fixing relief valve, institute
The bottom surface for stating upper cover has the sealing surface of gluing, sealing ring recess.
Preferably, the both sides of the installation screw form the nameplate installing zone of recess.
Preferably, the heat dissipation raised line extends along upper cover long side and linear array is in its top surface.
Preferably, the otic placode with through-hole is formed on the long lateral wall of the upper cover, the long lateral wall of the pedestal
On form threaded block corresponding with otic placode.
Preferably, the quadrangle of the upper cover forms through-hole, the top surface quadrangle of the pedestal forms screw hole.
Preferably, forming two groups of footing holes on the long lateral wall of the pedestal.
The beneficial effects of the utility model are：It is reasonable in design, sealing ring is embedded in seal groove, while connecing
It is embedded the rubber stopper with string holes in line mouth, improves the leakproofness of control box, be spirally connected relief valve in installation screw, moreover it is possible to control
The high pressure in box caused by high temperature avoids aging and damage caused by making moist due to control box interior circuit board.
Description of the drawings：

Specific implementation mode：
As shown in Figure 1, the waterproof control box for electric bus, including pedestal 1 and the upper cover for being bolted in 1 top surface of pedestal
2, the pedestal 1 is rectangular, and inside forms the chamber for accommodating circuit board, and the chamber bottom is equipped with several guide posts 3
With threaded post 4, several connection jaws 5 are formed on the long side wall side of the pedestal 1, are molded on the top surface of the pedestal 1 semiclosed
Seal groove 6,2 top surface of the upper cover forms several heat dissipation raised lines 7, and the lower end of the heat dissipation raised line 7 is equipped with for fixing
The installation screw 8 of relief valve, the bottom surface of the upper cover 2 have the sealing surface of gluing, sealing ring recess 6.
Specifically, the both sides of the installation screw 8 form the nameplate installing zone 9 of recess.
Specifically, the heat dissipation raised line 7 extends along 2 long side of upper cover and linear array is in its top surface, this setting can improve
The heat dissipation performance of control box.
Specifically, the otic placode 10 with through-hole, the long outside of the pedestal 1 are formed on the long lateral wall of the upper cover 2
Threaded block 11 corresponding with otic placode 10 is formed on wall, this setting, which facilitates, is fixed on control box on vehicle body.
Specifically, the quadrangle of the upper cover 2 forms through-hole, and the top surface quadrangle of the pedestal 1 forms screw hole, this setting
For upper cover 2 and pedestal 1 to be spirally connected fixation.
Specifically, two groups of footing holes 12 are formed on the long lateral wall of the pedestal 1.
When assembling, by circuit board sleeve after being positioned in guide post 3, circuit board is passed through to be connect admittedly with threaded post 4 with screw
It is fixed, it is embedded sealing ring in seal groove 6, the electric wire for connecting circuit board passes through the rubber stopper with string holes, and rubber stopper is embedded
In connection jaws 5,2 top surface of upper cover is spirally connected relief valve and to be spirally connected fixation by screw and pedestal 1, finally passes through footing hole with screw
12 are fixed on control box on vehicle body.
The above is only the preferred embodiment of the present invention, and those of ordinary skill in the art are not making creativeness
The every other embodiment obtained under the premise of labour should all belong to the range of the utility model protection.
