Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an electric vehicle controller casing includes

casing

1, 1 inside buffering protection device 2 that is provided with of casing, 1 both sides slip joint of casing has

visor

3, 1 inside spout 7 that is provided with of casing, sliding connection has sliding plate 8 on the

spout

7, 8 up end fixedly connected with telescopic link 9 of sliding plate, board 10 is placed to 9 up end fixedly connected with of telescopic link, spring 11 has been cup jointed to telescopic link 9 outside, 11 one end of spring and the fixed connection of placing board 10, place board 10 up end fixedly connected with fixed block 12, rotate on the fixed block 12 and be connected with and rotate layering 13, it is provided with circuit control board 15 to place board 10 up end, 1 inside power 16 that is provided with of casing.

In this embodiment, the rotating pressing bar 13 is sleeved with a torsion spring 14. Through pulling the sliding plate 8 with the hand and making it pull out from spout 7, pull open the rotation layering 13 with the hand and place the controller circuit board on placing board 10, it is fixed with the controller circuit board to turn around under torsional spring 14's effort from opening the hand, avoid going the in-process at the electric motor car and lead to dropping, can go on ground at unevenness because the electric motor car is inevitable, can make whole automobile body jolt, thereby make inside controller circuit board jolt rock, it can take place to damage with the inside collision of casing 1 to avoid, place board 10 can extrude telescopic link 9 and make its downstream at the in-process of jolting, spring 11 between board 10 and the sliding plate 8 is placed in the extrusion simultaneously, thereby make spring 11 give a reverse power and alleviate jolt and bring rocking.

In this embodiment, a cooling plate 18 is disposed on an inner wall of the housing 1, and the cooling plate 18 is electrically connected to the power supply 16. Thereby make the power circular telegram drive cooling plate 18 operation through the electric motor car circular telegram, because the controller circuit board of this self is exactly in an inclosed space, the air does not circulate and the long-time operation of circuit board leads to the overload can take place the temperature rise unavoidably, can lead to the circuit board to damage in the long term, can cool down to whole casing 1 inside after cooling plate 18 opens to the low temperature operation in the protection casing 1.

In this embodiment, the lower portion of the protection cover 3 is fixedly connected with a connecting block 4, the connecting block 4 is in threaded connection with a screw 5, and a sealing ring 6 is arranged inside the protection cover 3. Through adding sealing washer 6 in the gap of protective cover 3, with the side slip joint of protective cover 3 and casing 1, pass connecting block 4 and sweep threaded connection fixed with screw 5, thereby because storage battery car itself is waterproof not pasting that one of other time controller of water intaking leads to the short circuit easily to influence normal use, thereby has had the sealing washer and can stop rivers and avoid entering into the inside protection control ware circuit board of casing 1 outward.

In this embodiment, the protective cover 3 is provided with a charging port 17. Charging the power supply of the entire controller through the charging port 17 does not require disassembly for charging to save time.

In this embodiment, the housing 1 itself is made of a stainless steel material.

When the electric vehicle works, firstly, the sliding plate 8 is pulled by hand to be pulled out from the sliding chute 7, the rotary pressing strip 13 is pulled by hand to place the controller circuit board on the placing plate 10, the electric vehicle rotates under the action of the torsion spring 14 from the beginning to fix the controller circuit board, the falling of the electric vehicle in the running process is avoided, the electric vehicle inevitably runs on the uneven ground to cause the whole vehicle body to jolt, so that the controller circuit board in the electric vehicle jolts and shakes, the electric vehicle inevitably collides with the inside of the shell 1 to cause damage, the placing plate 10 extrudes the telescopic rod 9 to cause the telescopic rod 9 to move downwards in the jolt process, and simultaneously extrudes the spring 11 between the placing plate 10 and the sliding plate 8, so that the spring 11 gives a reverse force to relieve the jolt and shake, the electric vehicle is electrified to enable the power supply to drive the cooling plate 18 to run, and the controller circuit board is in a closed space, the long-time operation of air non-circulation plus circuit board leads to the overload can take place the temperature rise inevitably, can lead to the circuit board to damage long time, can cool down to whole casing 1 inside after cooling plate 18 opens, thereby the low temperature operation in the protection casing 1, through adding sealing washer 6 in the gap at protection cover 3, with the side sliding clamping of visor 3 with casing 1 on, it is fixed with sweep threaded connection to pass connecting block 4 with screw 5, thereby because that the controller is intake and leads to the short circuit easily to influence normal use when the waterproof subsides of storage battery car itself do not, thereby it can block rivers and avoid getting into casing 1 inside protection controller circuit board outside to have the sealing washer, charge through the power of the whole controller and need not dismantle the time-saving that charges. The whole electric vehicle controller shell is convenient for fixing the controller circuit board and buffering in bumping through the matching between the spring 11 and the torsion spring 14, so that the whole device is protected; through the cooperation between the power supply 16 and the cooling plate 18, the interior of the whole device is conveniently cooled, so that the internal device is prevented from running in an overload manner; through the cooperation between connecting block 4 and the sealing washer 6, the convenience is sealed the shell of whole device and is avoided the rainy day to lead to rivers to get into and lead to the short circuit damage.
