Technical field

The utility model is related to electric automobile accessory field, particularly a kind of battery bag for being used to deposit batteries of electric automobile Casing.

Background technology

Ev industry is actively promoted with the development and country of electric vehicle engineering, electric vehicle engineering is obtained Quick development is arrived.Battery pack is as the significant components of electric automobile, and the development to electric vehicle engineering plays important push away Action is used.Batteries of electric automobile group is made up of multiple battery tandem stacks.The plurality of battery will integrally be stacked in battery bag casing In, according to professional standard, battery bag casing will meet the requirement of IP67 standards.Existing battery bag body structure as shown in Figure 1, The bending laterally of lower box top, upper lid is simultaneously to after outside bending, and downward bending, is then placed on lower box by upper again On, upper sealing strip is padded between the two, is fixedly connected using screw rod.Which waterproof effect is poor, and water can be flowed into along screw rod Inside lower box, it is difficult to meet IP67 requirement.Accordingly, it would be desirable to which a kind of new technical scheme improves the IP67 of battery bag casing It is required that.

Utility model content

The purpose of this utility model is to provide a kind of new battery bag body structure, to improve the waterproof of battery bag casing Performance, the utility model provides following technical scheme：

A kind of in-flanges structure battery lodge body, the casing includes lower box and upper lid, and the upper edge of the lower box has The Z-shaped bending structure of turnover on the inside of the oriented lower box, the Z-shaped bending knot that the upper lid is turned down with upward outer side of lid direction Structure, the bending structure of the lower box is engaged with the bending structure of the upper lid.

As a kind of preferred scheme of the present utility model, being provided with the Z-shaped bending structure of the lower box is used for and institute The spiro cap that top cap connects is stated, the spiro cap is upper opening, the cylindrical structure of sealed bottom.The spiro cap and lower box Between for be seamlessly connected, if that is, from the downward pouring in top of spiro cap, during water will not be flowed into casing from spiro cap position.

As another preferred scheme of the present utility model, the Z-shaped bending structure of the lower box is included by lower box top Portion to horizontal-extending cross break side on the inside of the lower box, from the outlying one end from the lower box top-direction of the cross break to The vertical flanging of upper extension.

As another preferred scheme of the present utility model, the spiro cap is installed on the cross break side.The nut Cover and installed for vertical direction.

As another preferred scheme of the present utility model, the upper lid includes the first folding that cover rim is extended downwardly Side, from the one end of the first flanging away from cover rim to be distanced laterally from upper lid side extend the second flanging and by second The 3rd flanging that one end of flanging is extended downwardly, first flanging is engaged with the vertical flanging, second flanging and institute State cross break side to be engaged, the 3rd flanging is engaged with the side of the lower box.

It is used as another preferred scheme of the present utility model, the bending knot of the bending structure of the lower box and the upper lid The junction that structure is engaged is provided with sealing ring.

The utility model advantage is：

1st, the utility model by by battery bag lower box upper edge carry out to inward side to Z-shaped bending, in battery bag Lid carries out Z-shaped bending in outward direction, and both cooperate, while using sealed spiro cap on lower box bending edges, makes Battery bag box house can not be directly entered, it is necessary to could enter inside by repeatedly turning, so as to improve by obtaining external water source Water resistance, the requirement for making it meet IP67；

2nd, the utility model is by the way that lower box upper edge to inward side to bending, to be realized to battery bag casing overall space Raising.The space of placing battery lodge body is fixed on usual electric automobile, if using existing scheme, i.e., as shown in Figure 1 Scheme, then the lower section of casing junction can not placing battery, and use the technical solution of the utility model after, casing junction Lower section, that is, bending attachment structure lower section, can effective placing battery, it is achieved thereby that the raising of battery bag cabinet space.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite Define.

As the utility model structural representation of accompanying drawing 2, the utility model Structure explosion diagram of accompanying drawing 3 and 4 practicalities of accompanying drawing are new Shown in type marginal texture sectional view, a kind of in-flanges structure battery lodge body, the casing includes lower box 1 and upper lid 2, lower box 1 upper edge has the Z-shaped bending structure to the turnover of the inner side of lower box 1, and upper lid 2 has the Z-shaped of upward outer side of lid direction turnover Bending structure, the bending structure of lower box 1 is engaged with the bending structure of upper lid 2.

The Z-shaped bending structure of lower box 1 include by the horizontal-extending cross break side 11 in the inner side of 1 top down casing of lower box 1, The vertical flanging 12 upwardly extended by the one end of cross break side 11 away from the top-direction of lower box 1.It is downward that upper lid 2 includes cover rim First flanging 21 of extension, the extended from first one end of flanging 21 away from cover rim to the side for being distanced laterally from upper lid 2 Two flangings 22 and the 3rd flanging 23 extended downwardly by one end of the second flanging 22, the first flanging 21 match with vertical flanging 12 Close, the second flanging 22 is engaged with cross break side 11, and the 3rd flanging 23 is engaged with the side of lower box 1.

Spiro cap 41 for being connected with upper lid 2 is installed, spiro cap 41 is top on the Z-shaped bending structure of lower box 1 Opening, the cylindrical structure of sealed bottom.Spiro cap 41 is installed on cross break side 11.When upper lid 2 is placed on lower box 1, screw rod 42 are screwed into spiro cap 41 downwards from the second flanging 22 of upper lid 2, and sealing is provided between the second flanging 22 and cross break side 11 Circle 3.

If moisture will enter in casing, it is necessary to be flowed up from the inner side of the 3rd flanging 23, by sealing ring 3, then Flow up, can just enter in casing by vertical flanging 12, drastically increase the difficulty that moisture enters battery bag casing, make Obtain the requirement that battery bag casing meets classification of waterproof.

It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to In this, any those skilled in the art, can be without creative labor in the technical scope disclosed by the utility model The dynamic change or replacement expected, should all cover within protection domain of the present utility model.Therefore, protection model of the present utility model Enclosing be determined by the scope of protection defined in the claims.
