Abstract
The utility model relates to a kind of waterproof power distribution unit case of electric car, and the power distribution cabinet has waterproof construction, and the waterproof construction can guarantee the safety of car body, and then guarantee the personal safety of user.
Description
Technical field
The utility model relates to automobile power source field more particularly to a kind of waterproof power distribution unit casees of electric car
Body.
Background technique
Under the background of New-energy electric vehicle fast development, vehicle insulation safety performance quality directly affects the people of user
Body safety.And power distribution unit (PDU) is the brain of vehicle power supply power supply, the main portion such as control and data transmission
Point.However, power distribution unit in the prior art is easier to break down, one of reason is exactly to place power distribution list
The cabinet (PDU cabinet) of member can seep water in any case or this leak, causes power distribution unit short circuit, affects electronic
The stability and security performance of automobile.By analysis and summary, PDU cabinet in the prior art does not have applicant during drenching with rain
Drainage grade is set, ponding is easy to produce；PDU cabinet can often include cabinet, case lid and be set to close between cabinet and case lid
Seal, sealing ring can be accelerated to harden in cabinet and case lid press for a long time, and then waterproofing grade declines, and has the danger into water
Danger；The sealing ring production cost of PDU is excessively high
Utility model content
In view of this, the application provides a kind of waterproof power distribution unit cabinet.
The power distribution cabinet has cabinet, case lid；The power distribution unit cabinet, which has, is capable of Quick drainage
The gradient.
Optionally, the side of the cabinet has a groove, and the groove has upper top, side and bottom face, institute
Stating bottom face is inclined-plane, and the gradient of Quick drainage is capable of described in formation；
Optionally, the groove is formed in the opening of the cabinet, and around the entire opening.
Optionally, the outer surface of the cabinet is coated with a material layer, and the material layer can be heat-conducting layer or hydrophobic
Layer.
On the other hand, the case lid has sealing ring towards the side of box house, and optionally, the sealing ring is a plurality of
The splicing sealing ring that sealing strip is spliced；
Optionally, the upper top of the groove of the cabinet and the sealing ring all have location hole, when the case
When lid is placed on the cabinet, the location hole alignment of the location hole of the upper top of the groove and the sealing ring, into
One step, the case lid is fixed on the cabinet by the location hole using screw and nut, the sealing ring sealing
The power distribution unit cabinet.
Detailed description of the invention
By the description below with reference to attached drawing to the utility model embodiment, the above-mentioned and other mesh of the utility model
, feature and advantage it is apparent, in the accompanying drawings:
Fig. 1 is the waterproof power distribution unit case of the utility model embodiment；
Fig. 2 is the sectional view of the waterproof power distribution unit case of the utility model embodiment；
Fig. 3 is the cover structure of the waterproof power distribution unit case of the utility model embodiment.
Specific embodiment
The utility model is described below based on embodiment, but it is worth noting that, the utility model is simultaneously unlimited
In these embodiments.It is detailed to describe some specific detail sections below in the datail description of the utility model.So
And for the part of no detailed description, the utility model can also be understood completely in those skilled in the art.
Meanwhile unless the context clearly requires otherwise, "include", "comprise" etc. otherwise throughout the specification and claims
Similar word should be construed as the meaning for including rather than exclusive or exhaustive meaning；That is, being " including but not limited to "
Meaning.
Power distribution unit case as illustrated in fig. 1 and 2, the power distribution unit case has cabinet 1 and case lid 2, described
Cabinet 1 is the cuboid that top has opening, and the case lid 2 is matched with the opening on the cabinet top, is placed on the cabinet 1
On, and cover the opening and seal the cabinet 1.
The groove that the side tool one of the cabinet 1 is recessed to box house, optionally, the extending direction of the groove is in water
Plane is parallel；The groove has upper top, side and bottom face, and the bottom face is inclined-plane 3, can described in formation
The gradient of Quick drainage；The inclined-plane and the side form an obtuse angle.Optionally, the top of each side of the cabinet 1
Portion all has the groove, and the groove of each side is located at the same horizontal position；Optionally, each side
The groove is interconnected to an enclosed construction.
Optionally, the inside grooves surface is coated with hydrophobic material layer, to further avoid ponding.
Optionally, the tank surface has a material layer, and the material layer can paint commonly, heat-conducting layer or hydrophobic
Layer.
As shown in figure 3, being equipped with sealing ring 7 on the inside of the case lid 2, the sealing ring 3 is that four sealing strips are spliced.It can
Selection of land, the sealing strip have adhesion layer towards 2 side of case lid.
The sealing ring has multiple first positioning holes across the sealing strip and case lid 2, the cabinet 1 it is described recessed
The upper top of slot have multiple second location holes, when covering case lid 2 when on the cabinet 1, the first positioning hole and institute
State second location hole alignment；Multiple screws 6 pass through the multiple first positioning hole and second location hole, the multiple screw 6 into
One step and multiple nuts 5 form fastening structure.
In case lid and cabinet engagement process when screw is tightened to nut, splicing sealing ring is also shunk in pressing, works as receipts
When reaching IP67 waterproof requirement, locating ring is also just within this range.Sealing ring is also that 30%~50% material is received at this time
Within the scope of contracting, reach optimum range.
Embodiment described above is only to express the embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that the ordinary skill people of this field
For member, without departing from the concept of the premise utility, several deformations, same replacement can also be made, improved etc., these
Belong to the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
