Fig. 1 is the schematic diagram of the lower body structure of electronlmobil according to an embodiment of the invention.
Detailed description of the invention
Fig. 1 is the schematic diagram of the lower body structure of electronlmobil according to an embodiment of the invention.The lower body structure of the electronlmobil of the present embodiment comprises two underframe longitudinal members 10, centre gangway 20 and diagonal ligament plate 30, the battery installing space of electronlmobil is formed between two underframe longitudinal members 10, battery installing space is see the A place, rectangular area marked in Fig. 1, centre gangway 20 is between two underframe longitudinal members 10, and centre gangway 20 is identical with the bearing of trend of underframe longitudinal member 10.Diagonal ligament plate 30 is fixedly connected with underframe longitudinal member 10 respectively at centre gangway 20, and the bearing of trend of diagonal ligament plate 30 and the bearing of trend of underframe longitudinal member 10 have the first angle.The angle of the first angle is between 30 degree to 70 degree, and in an embodiment preferably, the angle Selection of the first angle is 45 degree.
The lower body structure of electronlmobil, by the frame form of himself structure, carries out actv. protection to electrokinetic cell, protection battery security.When front shock, impact load can carry out load decomposition by multiple paths of centre gangway and diagonal ligament plate, avoids dynamic changes process to battery module, ensures that territory, Battery compartment moderate finite deformation does not occur.
See Fig. 1, two underframe longitudinal members 10 of the lower body structure of the present embodiment extend along bodywork length direction, each underframe longitudinal member 10 comprises first paragraph 11, second segment 12 and the 3rd section 13, second segment 12 is between first paragraph 11 and the 3rd section 13, have the second angle between the bearing of trend of second segment 12 and first paragraph 11, the angle of the second angle is between 30 degree to 50 degree.First paragraph 11 is fixedly connected with the front side member 40 of electronlmobil, the outside being positioned at electronlmobil relative to first paragraph 11 for the 3rd section 13.As seen from Figure 1, underframe longitudinal member 10 is the longerons with certain bending section, owing to being formed with the second angle between second segment 12 and first paragraph 11, therefore when battery-driven car receives front shock, the impact energy of first paragraph 11 is delivered to the 3rd section of 13 places by second segment 12 and carries out decomposition load, 3rd section 13 everywhere in the edge of battery installing space, even if there is certain distortion also can not produce considerable influence to battery module.
Lower body structure also comprises two thresholds 50, two thresholds 50 are separately positioned on the outside of two underframe longitudinal members 10, each threshold 50 is fixedly connected with the 3rd section 13 of underframe longitudinal member 10 near the part of first end, and threshold 50 has distance near the part of the second end with first paragraph 11.When side collision or post touch, threshold and underframe longitudinal member carry out actv. cross-tie, improve vehicle body lateral rigidity, reduce side direction and invade, protection battery security.
Lower body structure also comprises two the first connecting panels 61 and two the second connecting panels 62, and one end of each connecting panel is fixedly connected on one of them threshold 50 and is fixedly connected between the first paragraph 11 of corresponding underframe longitudinal member 10 near the part of the second end, the other end.One end of each second connecting panel 62 is fixedly connected on the first paragraph 11 of one of them underframe longitudinal member 10, the other end is fixedly connected on centre gangway 20.
Lower body structure also comprises cross-tie plate 70, and cross-tie plate 70 is extended along the horizontal direction of electronlmobil, and the two ends of cross-tie plate 70 are fixedly connected on two the second connecting panels 62 respectively.The impact load that cross-tie plate 70 receives for absorbing the second connecting panel 62, and strengthen the intensity of centre gangway 20.
The bearing of trend of the bearing of trend of the second connecting panel 62 and the first paragraph 11 of underframe longitudinal member 10 has the 3rd angle, and the 3rd angle is less than 90 degree.Diagonal ligament plate 30, first connecting panel 61, two the second connecting panels 62 of the present embodiment and cross-tie plate 70 are all adopt the material of high strength to make, as steel, alloy material etc.
As shown in fig. 1, the direction of arrow is the transmission direction of the impact load when front shock, as can be seen from Fig. 1, load on the second segment 12 of the first connecting panel 61, underframe longitudinal member 10 to decompose threshold 50 and underframe longitudinal member 10 towards the lateral direction of vehicle the 3rd section 13, and through the second connecting panel 62 and diagonal ligament plate 30 towards vehicle interior side Directional Decomposition on cross-tie plate 70 and centre gangway 20.Carry out load decomposition through multiple path like this, avoid dynamic changes process to battery module, ensure that territory, Battery compartment moderate finite deformation does not occur.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present invention is illustrate and described herein detailed, but, without departing from the spirit and scope of the present invention, still can directly determine or derive other modification many or amendment of meeting the principle of the invention according to content disclosed by the invention.Therefore, scope of the present invention should be understood and regard as and cover all these other modification or amendments.
