Description
Technical field
The utility model relates to electric automobile accessory field, is specifically related to the lower shoe of batteries of electric automobile group.
Background technology
Along with the continuous consumption of the energy, greenhouse effect and atmosphere polluting problem increasingly serious, electric automobile research and development have become the important trend of Global Auto enterprise development.
Part New-energy electric vehicle forms based on changing a social system on conventional fuel oil Automobile basis, and power battery pack is arranged in below bottom of car, and with lower shoe carrying battery pack, battery pack arrangement space directly has influence on distance travelled.
The lower shoe mainly sheet metal component of batteries of electric automobile group in the market, the direct bending welding of simple sheet metal component, cost is lower; Complex Panels then needs by mould punching shaping, and surface treatment generally adopts electrophoretic paint technique.In use, there is lower shoe and cause battery surface electrophoretic paint damaged due to scraping, easily cause for a long time and get rusty; Sheet metal component mainly through welding, electrophoretic process, exist local location electrophoresis less than, cause for a long time getting rusty, and Complex Panels welding controlling distortion become important problem.
Utility model content
The purpose of this utility model is the problem of rustiness of the lower shoe overcoming batteries of electric automobile group, provides a kind of space to arrange the lower shoe of more reasonably batteries of electric automobile group.
For achieving the above object, the utility model provides following technical scheme:
A kind of lower shoe of batteries of electric automobile group, described lower shoe is casting integrated molded part, rectangular configuration is surrounded by diapire and four sidewalls, each described sidewall all has hanger, described hanger has the first bolt hole, described diapire has a point muscle, and described diapire is divided into two mutual disconnected chambers by described point of muscle, and described point of muscle has the second bolt hole.
Preferably, described point of muscle has the boss stretching to described chamber, and described second bolt hole is opened on described boss.
Preferably, described boss is multiple and spaced, and described chamber is separated into multiple positioning unit by described boss.
Preferably, described hanger is flute profile.
Preferably, the upper surface of described hanger is not higher than the end face of described sidewall.
The utility model adopts the structure of casting integrated molded part, avoid the risk of weld electrophoresis less than easy-to-rust, and be separated out two mutual disconnected chambers, chamber indoor location battery pack with a point muscle, divide muscle both to play structural strengthening effect, play again and prevent battery pack scraping effect.
Further, the utility model adopts the boss on point muscle that chamber is separated into multiple positioning unit, and boss plays booster action to a point muscle and plays battery pack and prevents mutual scraping effect.
Further, the upper surface of hanger is not higher than the end face of sidewall, and lower shoe is installed to after below vehicle body through hanger by bolt, can ensure that battery pack is not swiped with vehicle body.
Accompanying drawing explanation
Next will be described in further detail specific embodiment of the utility model by reference to the accompanying drawings, wherein:
Fig. 1 is the stereogram of the lower shoe of embodiment of the present utility model;
Fig. 2 is the stereogram after the lower shoe upset in Fig. 1.
Description of symbols in upper figure: lower shoe 100, diapire 110, point muscle 111, first chamber 112, second chamber 113, boss 114, second bolt hole 115, positioning unit 116, sidewall 120, end face 121, hanger 130, first bolt hole 131, upper surface 132, end wall 133, first wall 134, second wall 135.
Embodiment
With reference to figure 1, the lower shoe 100 of the batteries of electric automobile group in the present embodiment is casting integrated molded part, replace multiple the welding of sheet metal parts structure of the prior art, avoid the risk of weld electrophoresis less than easy-to-rust, and effectively can solve battery water inlet, guarantee integral strength and rigidity.Lower shoe 100 surrounds rectangular configuration by diapire 110 and four sidewalls 120, and each sidewall 120 all has hanger 130, each hanger has the first bolt hole 131.During installation, bolt is adopted to be fastened to below vehicle body by lower shoe 100 through the first bolt hole 131.Diapire 110 has point muscle 111, muscle 111 is divided diapire 110 to be divided into the first chamber 112 and the second chamber 113, two chambers are not communicated with mutually, for installing battery pack in first chamber 112 and the second chamber 113, like this, divide muscle 111 both to play structural strengthening effect, play again and prevent battery pack scraping effect.Muscle 111 is divided to have the multiple boss 114 stretching to the first chamber 112, second chamber 113, each boss 114 has the second bolt hole 115, first chamber 112 or the second chamber 113 are separated into independent positioning unit 116 by two adjacent boss 114, therefore in two chambers, there is multiple positioning unit 116, in the second bolt hole 115, be screwed into bolt thus battery pack be fastened in positioning unit 116, like this, boss 114 plays booster action to a point muscle 111 and plays the battery pack in the first chamber 112 and the second chamber 113 and prevents mutual scraping effect.
With reference to figure 2, hanger 130 surrounds flute profile by the first wall 134, second wall 135 and end wall 133, and as seen from Figure 1, the upper surface 132 of hanger 130 is not higher than the end face 121 of sidewall 120, like this, lower shoe 100 is installed to after below vehicle body through hanger 130 by bolt, can ensure that battery pack does not produce with vehicle body and swipe.Adopt bolt battery pack to be installed in positioning unit 116, the mounting means be installed to below vehicle body also makes the easier for installation of battery pack by lower shoe 100 to adopt bolt.
Although the utility model is described in conjunction with above embodiment, the utility model is not limited to above-described embodiment.Those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
