Description

Technical Field

[0001] The invention relates to an electric vehicle control mainboard, in particular to a dust-proof and heat-dissipating electric vehicle control mainboard. Background Art

[0002] In order to realize various control functions, electric vehicles need to be equipped with more electronic components on the control motherboard. A large amount of heat will be generated during operation, which needs to be dissipated in time. In order to dissipate heat, the existing electric vehicle control motherboard generally uses a fan to blow air, which not only easily brings impurities into the control motherboard, causing short circuit damage to the control motherboard, but also increases power consumption. Summary of the invention

[0003] The object of the present invention is to provide a dust-proof and heat-dissipating electric vehicle control mainboard which can dissipate heat in time while reducing the entry of impurities into the control mainboard and consuming no unnecessary electricity.

[0004] The technical solution for achieving the purpose of the present invention is as follows:

[0005] A dustproof and heat-dissipating electric vehicle control mainboard comprises a base, a support column fixed on the base, and a mounting plate fixed on the support column, wherein the mounting plate is provided with a through hole, a circuit mainboard is fixed in the through hole, an upper cover covering the upper end of the through hole is provided on the upper surface of the mounting plate, and a lower cover covering the lower end of the through hole is provided on the lower surface of the mounting plate;

[0006] The upper surface of the mounting plate is provided with a plurality of circles of closed first protrusions, and the side of the upper cover facing the mounting plate is provided with a plurality of circles of closed second protrusions, the first protrusions and the second protrusions are arranged alternately along the direction from the inner circle to the outer circle, and a labyrinth sealing structure is formed between the upper cover and the mounting plate; a first elastic support member is provided between the mounting plate and the upper cover, a gap is provided between the first protrusion and the upper cover, and a gap is provided between the second protrusion and the mounting plate;

[0007] The lower surface of the mounting plate is provided with a plurality of closed circles of third protrusions, and the side of the lower cover facing the mounting plate is provided with a plurality of closed circles of fourth protrusions, the third protrusions and the fourth protrusions are arranged alternately along the direction from the inner circle to the outer circle, and a labyrinth sealing structure is formed between the lower cover and the mounting plate; a second elastic support member is provided between the lower cover and the base, a gap is provided between the third protrusion and the lower cover, and a gap is provided between the fourth protrusion and the mounting plate.

[0008] After adopting the above structure, a labyrinth sealing structure is formed between the first protrusion and the second protrusion, and a labyrinth sealing structure is also formed between the third protrusion and the fourth protrusion. During the driving of the electric vehicle, the vibration of the electric vehicle drives the upper cover and the lower cover to vibrate slightly up and down, which can absorb the vibration energy transmitted to the circuit main board by the electric vehicle, and reduce the risk of the circuit main board being broken or the electronic components falling off due to excessive vibration of the circuit main board. At the same time, the vibration of the upper cover and the lower cover can drive the flow of air in the space surrounded by the upper cover, the mounting plate and the lower cover, which facilitates the dissipation of heat, and the labyrinth sealing structure avoids the situation where impurities enter the control main board during the heat dissipation process. The present invention can achieve heat dissipation while reducing the situation where impurities fall on the circuit main board, and at the same time does not consume extra electricity, reducing energy consumption and usage costs.

[0009] Preferably, the first elastic support member and the second elastic support member are springs.

[0010] Preferably, the first protrusion and the second protrusion are in the shape of square rings.

[0011] Preferably, the first protrusion and the second protrusion are in the shape of a circular ring.

[0012] Preferably, the third protrusion and the fourth protrusion are in the shape of square rings.

[0013] Preferably, the third protrusion and the fourth protrusion are in the shape of a circular ring.

[0014] Preferably, the cross-sections of the first protrusion and the third protrusion are rectangular.

[0015] Preferably, the cross-sections of the first protrusion and the third protrusion are T-shaped.

[0016] Preferably, in order to reduce the impact on the ends of the first protrusion, the second protrusion, the third protrusion and the fourth protrusion due to collision, rubber buffer pads are provided on the ends of the first protrusion, the second protrusion, the third protrusion and the fourth protrusion.
