Abstract
The utility model discloses a kind of internal and external pressure balance mechanism of electric machine controller, including bottom plate and pcb board, the pcb board is fixed on bottom plate, shell provided with encapsulation pcb board above the pcb board, the ventilated membrane group that covering air-vent is provided with least one set of ventilation part being made up of multiple air-vents, the ventilation part is provided with the shell.Controller can be made in the case where inner and outer ring temperature changes, can also keep the pressure inside controller to be consistent with outside air pressure, eliminate causes damage of product because of external and internal pressure difference.
Description
Technical field
The utility model is related to a kind of internal and external pressure balance mechanism of electric machine controller, more particularly to a kind of electric car
The internal and external pressure balance mechanism of electric machine controller.
Background technology
Electric car is using electric power as driving, using electric power as the car of the energy, with the reinforcement of people's environmental consciousness, electric car
Turn into one of important vehicles of people's go off daily.Controlled as the electric car of one of the big core component of electric car three
Device, its reliable, security plays vital effect against the quality of vehicle.
At present, be usually in controller for electric vehicle be fully sealed it is not breathable, it is internal so when controller works
High-power electronic device will produce substantial amounts of heat so that the air themperature inside controller is raised rapidly, such controller
Internal air pressure increase, when increasing to a certain extent, may destroy the shell or other devices of product.In addition, when vehicle by
When low temperature drives into hot environment or drives into low temperature environment by high temperature, closed controller air pressure inside can also change, internal
The transformation of air pressure causes external and internal pressure uneven, may destroy product casing, easily water will be caused to enter when being such as internally formed negative pressure
Interiors of products, influences the safety of vehicle.
Utility model content
For the unbalanced problem of the external and internal pressure for solving current electric machine controller, the utility model purpose is：There is provided one
The internal and external pressure balance mechanism of electric machine controller is planted, controller can be made in the case where inner and outer ring temperature changes, can also be protected
Pressure inside held controller is consistent with outside air pressure, and eliminate causes damage of product because of external and internal pressure difference.
The technical solution of the utility model is：
A kind of internal and external pressure balance mechanism of electric machine controller, including bottom plate and pcb board, the pcb board are fixed on bottom plate,
Be provided with shell provided with encapsulation pcb board above the pcb board, the shell it is at least one set of by multiple air-vents constitute it is saturating
The ventilated membrane group of covering air-vent is provided with gas portion, the ventilation part.
It is preferred that, the first groove is provided with around the air-vent of the ventilation part, it is recessed that the ventilated membrane group is arranged on first
In groove.
It is preferred that, the ventilated membrane group includes carrier layer, ventilative film layer and adhesive layer.
It is preferred that, covering protection film above the ventilated membrane group, the diaphragm lower end is provided with adhesive glue, the protection
Correspondence ventilation part is provided with through hole on film, and the diaphragm is pasted onto the second groove of ventilation part periphery.
Compared with prior art, the utility model has the advantages that：
Ventilated membrane group gas-permeable of the present utility model but impenetrable liquid, are set by multilayer and top sets diaphragm
Can prevent ventilated membrane group come off or use during be damaged, effectively protection ventilated membrane group.Controller can be made in inner and outer ring
In the case that temperature changes, it can also keep the pressure inside controller to be consistent with outside air pressure, eliminate because inside and outside
The damage of product caused by pressure differential, so as to improve performance and the life-span of product, improves the security of vehicle.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the structural representation of ventilated membrane group of the present utility model.
Wherein, 1, shell, 2, ventilated membrane group, 3, diaphragm, the 11, first groove, 12, air-vent, the 13, second groove, 21,
Ventilative film layer, 22, adhesive layer, 23, carrier layer, 31, adhesive glue, 32, through hole.
Embodiment
To make the purpose of this utility model, technical scheme and advantage of greater clarity, with reference to embodiment
And referring to the drawings, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid not
Necessarily obscure concept of the present utility model.
Embodiment：
As shown in figure 1, a kind of internal and external pressure balance mechanism of electric machine controller, including bottom plate and pcb board, pcb board is fixed

The ventilation part that stomata 12 is constituted, the present embodiment is two ventilation parts, is arranged side by side.Covering air-vent 12 is provided with ventilation part
Ventilated membrane group 2.
The first groove 11 is provided with around the air-vent 12 of each ventilation part, ventilated membrane group 2 is arranged in the first groove 11.
As shown in Fig. 2 the ventilated membrane group 2 of the present embodiment includes three layers, respectively carrier layer 23, ventilative film layer 21 and viscous
Close layer 22.Ventilated membrane group 2 is bonded in the first groove 11 by adhesive layer 22.The shape of ventilative module 2 can be circle.
The top of ventilated membrane group 2 is also covered with diaphragm 3, and the lower end of diaphragm 3 is provided with adhesive glue 31, diaphragm 3
The position of correspondence ventilation part is provided with through hole 32, the second groove 13, the second groove 13 are provided with the periphery of two ventilation parts
To be square, diaphragm 3 is pasted onto in the second groove 13 of ventilation part periphery.
Ventilated membrane group 2 is fixed to onto shell 1 by the utility model diaphragm 3 by the adhesive glue 31 of its lower surface, profit
With the gas-permeable but the particularity of impenetrable liquid of ventilated membrane group 2, the internal and external pressure balance of product is realized.
