Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, and object is to help those skilled in the art to have more complete, accurate and deep understanding to design of the present utility model, technical scheme, and contributes to its enforcement.
As shown in Figures 1 to 4, a kind of Waterproof battery bag of the utility model, comprises upper shell 1 and lower house 2, and upper shell 1 covers on lower house 2, and upper shell 1 and lower house 2 are connected to form the shell of power brick, and enclosure is for holding the space of battery component.This Waterproof battery bag also comprises the first sealing ring 6, and the edge of upper shell 1 is provided with upper overturning 4, and the edge of lower house 2 is provided with lower flange 5, the first sealing rings 6 that are connected by securing member with upper overturning 4 and is clipped between upper overturning 4 and lower flange 5.
Specifically, the material of the first sealing ring 6 is closed pore silica-gel sponge or porous silica gel sponge, have stronger sealing property, the features such as high resilience energy, serviceability temperature wide scope (50 ℃～260 ℃), can further improve the water resistance of power brick.
As preferably, upper overturning 4 is provided in a side of the edge of the opening towards lower house 2 of upper shell 1, and extends along the whole edge of upper shell 1, and be towards the outside of upper shell 1 protrusion.Lower flange 5 is provided in a side of the edge of the opening towards upper shell 1 of lower house 2, and extends along the whole edge of lower house 2, and is to protrude towards lower house 2 outsides.Upper overturning 4 is parallel with lower flange 5, and both shapes are basic identical, and the shape of the shape of the first sealing ring 6 and upper overturning 4 and lower flange 5 is also basic identical.
As preferably, the width of upper overturning 4 and lower flange 5 is 24mm, and this width can guarantee there are enough contacts area with the first sealing ring 6, guarantees that upper overturning 4 and lower flange 5 have suitable spatial dimension to compress the first sealing ring 6, to improve sealing property.
Because the overall volume of power brick is generally all larger, if the first sealing ring 6 adopts integral seal circle will produce higher production cost, and easily cause the waste of sealing strip, therefore, first sealing ring 6 of this power brick is the loop configuration being in turn connected to form by multistage sealing strip.In the present embodiment, the first sealing ring 6 is spliced by four sections of sealing strips.
As preferably, two sections of sealing strips that are connected on the first sealing ring 6 are to adopt the mode of clamping to connect, in two sections of sealing strips that are connected, wherein the link of one section of sealing strip is provided with the fixture block 61 of protrusion, the link of another section of sealing strip is provided with and allows fixture block 61 embed fixing draw-in groove 62, and one end of each section of sealing strip arranges fixture block 61, the other end arranges draw-in groove 62.
As shown in Figure 4, fixture block 61 be shaped as isosceles trapezoid, fixture block 61 is identical with sealing strip thickness, and both are in same plane.Draw-in groove 62 is the dovetail groove coordinating with fixture block 61, and draw-in groove 62 forms respectively an opening at the end face of sealing strip with relative two sides.One end that fixture block 61 width are little is connected with the link of sealing strip, and corresponding draw-in groove 62 equates at the width of the width of the opening of the end face formation of sealing strip one end little with the width of fixture block 61.
Sealing strip adopts above-mentioned fixture block 61 to be connected with the mode clamping that draw-in groove 62 coordinates, easy to connect, between sealing strip, be not easy to get loose, and good reliability, the sealing property of raising power brick.
Securing member for fixing upper overturning 4 and lower flange 5 is to consist of clamping screw 8 and staking nut 7, as shown in Figure 2, this securing member is evenly equipped with a plurality of along whole annular on upper overturning 4 and lower flange 5, guarantee that upper overturning 4 and lower flange 5 can clamp the first sealing ring 6, improve the sealing property of power brick, and can guarantee that upper shell 1 is connected reliably with lower house 2.
As preferably, as shown in Figure 3, staking nut 7 is to be welded on the lower surface of lower flange 5, and clamping screw 8 is passed down through after upper overturning 4 and lower flange 5 and is screwed in staking nut 7, and each section of sealing strip of upper overturning 4, lower flange 5 and the first sealing ring 6 is provided with the through hole that allows clamping screw 8 pass.The Main Function of staking nut 7 is except play the effect of fastening clamping screw 8 after upper shell 1 and lower house 2 close, another Main Function plays position-limiting action exactly, mainly at upper shell 1 and lower house 2, under the unified torsion of clamping screw 8, to compress post gap to be consistent, this has just guaranteed the consistency of inner the first sealing ring 6 decrements, except guaranteeing preferably sealing property, the decrement everywhere that can also guarantee upper overturning 4 and lower flange 5 keeps uniformity, prevent the first sealing ring 6 overvoltages and cause damaging, extend the useful life of the first sealing ring 6, prevent the appearance of weak spot, stop the existence of potential safety hazard.
As shown in Figure 2, on upper shell 1, be also provided with a service ports, and this service ports by a cover plate 3 sealing being connected with upper shell 1, between cover plate 3 and upper shell 1, be bolted, be convenient to dismounting and the installation of cover plate 3.Service ports be shaped as rectangular opening, the shape of corresponding cover plate 3 is also rectangle.
In order to improve the sealing at service ports place, between cover plate 3 and upper shell 1, be provided with second sealing ring, the material of the second sealing ring is also closed pore silica-gel sponge or porous silica gel sponge, there is stronger sealing property, the features such as high resilience energy, serviceability temperature wide scope (50 ℃～260 ℃).
In addition, the lower house 2 of this power brick is to be stretched and formed by DC06 material, and upper shell 1 is to be stretched and formed by QSTE340TM material, on upper shell 1 and lower house 2, all adds muscle and floor, can guarantee the bulk strength of power brick, have stronger compression set resistant ability.The peripheral weld of upper shell 1 and lower house 2 is connected to the fixed support for being connected with vehicle body, on support, be welded with location hole and backstay, with the accuracy that guarantees to be connected with vehicle body, and rust prevention by applying liquid material coatings on upper shell 1 and lower house 2, make its insulation safety performance reach perfect condition.
The Waterproof battery bag later stage of said structure is through a large amount of waterproof tests, adopt the moment of torsion of 10N.m evenly to lock all clamping screws in this power brick 8, whole power brick is sunk to the water tank of filling water, according to IPX7 test request, by this Waterproof battery bag 1 meter of that sinks under the water, keep after 30 minutes, power brick is pulled out after the water surface, unclamp clamping screw 8, open upper shell 1 and observe the inner anhydrous mark of power brick, illustrate that the hermetically-sealed construction in power brick meets IPX7 requirement completely.
