Specific embodiment
It should be noted that in the absence of conflict, the spy in embodiment and embodiment in the utility model
Sign can be combined with each other.
The utility model is described in detail below with reference to the accompanying drawings and in conjunction with embodiment.
The utility model provides a kind of lateral coaming plate of battery pack, and as depicted in figs. 1 and 2, the lateral coaming plate includes 1 He of frame
Sealing element 2 is formed with the cavity 3 of both ends perforation in the frame 1, is provided with multiple mounting holes 5 on the top surface 4 of the frame 1,
The sealing element 2 is arranged in the cavity 3 so that the part positioned at 2 two sides of sealing element of the cavity 3 is not connected to, described close
The top of sealing 2 fits in the top surface 4, and the lateral coaming plate includes at least two sealing elements 2, multiple mounting holes 5
On the part of the top surface 4 being located between two sealing elements 2.
When constituting the side round part of battery pack using the lateral coaming plate of the offer of the utility model, from the air of the entrance of mounting hole 5
Needing could be further to the internal penetration of battery pack by sealing element 2, and air is from lateral coaming plate in original lateral coaming plate
Mounting hole 5 enter after can directly to the internal penetration of battery pack, therefore original battery pack in order to guarantee sealing effect it is necessary to
Mounting hole 5 is sealed, it is general that the rivet nut with sealant is selected to be sealed each mounting hole 5.In contrast, originally
As long as the lateral coaming plate of battery pack described in utility model guarantees that the leakproofness of sealing element 2 can be realized as good sealing effect,
The complexity of assembly is significantly reduced, the reliability of battery pack is improved.
It should be noted that automobile is when paddling, battery pack is due to by water projection or impregnating in water, if battery pack
Poor sealing, then water is just able to enter the inside of battery pack, to damage the internal element of battery pack.In order to examine
The leakproofness of battery pack generallys use air tightness test in production to examine the leakproofness of battery pack, as long as guaranteeing battery pack
Air-tightness be to ensure that the waterproof performance of battery pack.The application guarantees do not have by guaranteeing the leakproofness of sealing element 2
Gas can penetrate internal penetration of the sealing element 2 to battery pack, ensure that the water entered from mounting hole 5 can not enter further into
The inside of battery pack, to protect the internal element of battery pack.
Wherein, two sealing elements 2 are included at least in the lateral coaming plate, the two sealing elements 2 need to be arranged in these mounting holes 5
Head and the tail both ends can obtain better seal effect in this way it is of course also possible to which more sealing elements 2 are arranged.But from economy
Property and assembly efficiency etc. consider, two sealing elements 2 are preferably set.
As shown in Fig. 2, frame 1 is internally provided with partition, cavity 3 is by partition and top surface 4 and the two sides structure of frame 1
At.As shown in figure 3, cavity 3 is horizontally extending, sealing element 2 guarantees the shape of the plate face of sealing element 2 using the plate of rigidity
The shape in the section of shape and cavity 3 matches, then sealing element 2 can be arranged in cavity 3 along the direction perpendicular to top surface 4,
To close mounting hole 5 to the access between battery pack inside, play the role of sealing.
Preferably, the section of sealing element 2 can select rectangle, and sealing element 2 can select the aluminium sheet of rectangle and select welding
Mode be arranged in cavity 3；Certain sealing element 2 can also be arranged 3 in cavity by binder.
In the another embodiment of present aspect, sealing element 2 can be flexible piece or elastic component, and sealing element 2
Extrusion packing is in cavity 3, and deformation occurs and is deformed into the section with cavity 3 for meeting when being squeezed for flexible piece or elastic component
The shape to match, to close the access inside mounting hole 5 to battery pack.Wherein, the section of cavity 3 should be avoided with rib
Angle, because sealing element 2 in the inner wall of edges and corners and cavity 3 it is difficult to ensure that be bonded, the edge in the section of cavity 3 is preferably justified
It slips over and crosses.The section of usual situation lower chamber 3 is rectangle, in order to enable the inner wall of sealing element 2 and cavity 3 is bonded, it can be in square
Fillet is selected at four angles of shape.Sealing element 2 can select foamed silica gel, and foamed silica gel is a kind of ep-type material, nontoxic nothing
Taste, stable chemical performance and air proof.
In addition, the utility model second aspect provides a kind of battery pack, which includes side round part, is arranged in the side
It encloses the top plate on portion top and the bottom plate of the side round part lower part is set, the side round part is first by multiple lateral coaming plates as described above
Tail connects to be formed.
With reference to structure shown in Fig. 3, four lateral coaming plates head and the tail are spliced to form the side round part of square frame-shaped, between each lateral coaming plate
It is connected to each other by welding, in a practical situation, it is well known in the art that battery pack can only guarantee each lateral coaming plate outer surface
Between weld seam sealing, and not can guarantee the sealing of the weld seam between each lateral coaming plate inner surface.Therefore, in automobile wading
When, if water is into mounting hole 5, the weld seam that water can further pass through between the inner surface of each lateral coaming plate enters
In battery pack, to be damaged to elements such as mould groups in battery pack.Therefore, it is necessary to be sealed place to each mounting hole 5
Reason sealing element 2 in the application block water from mounting hole 5 to battery pack inside path, only need to guarantee at least down to two
The sealing of sealing element 2 can prevent water from entering the inside of battery pack, without guaranteeing tens even a mounting holes 5 up to a hundred
Sealing, reduces assembly difficulty and cost.
It is of course also possible to use guaranteeing the sealing (for example sealant is arranged on mounting hole 5) of mounting hole 5 and close simultaneously
The mode of the sealing of sealing 2, this dual-seal has better seal performance, can be improved the reliability of battery pack.
In terms of third according to the present utility model, the utility model also provides a kind of automobile, which includes institute as above
The battery pack stated.
The foregoing is merely the better embodiments of the utility model, are not intended to limit the utility model, it is all
Within the spirit and principles of the utility model, it is practical new to should be included in this for any modification, equivalent replacement, improvement and so on
Within the protection scope of type.
