The vibration of vehicle is the important indicator for evaluating automotive performance.For complete vehicle structure, when by from road surface, hair The excited frequency of the exciting source such as motivation and transmission system close to or the exactly equal to intrinsic frequency of vehicle body entirety or part, will produce Raw covibration.Covibration can cause structure to be deformed and dynamic stress, and with violent vibration and noise, the vibration meeting The comfort level taken is influenceed, more serious meeting causes the destruction of body structure.So to avoid various forms as far as possible in design Vibration, so as to improve reliability and NVH (Noise, Vibration, Harshness) performance of vehicle.
Usual pure electric vehicle is considered to have the technical advantage of good vibration and noise, but in fact, is just currently in For the pure electric vehicle of development phase, advantage is not obvious compared with orthodox car.At present, pure electric vehicle refers to just completely by moving Power battery provides the electric motor car of driven by power, and power accumulator is important equipment component in vehicle body, supported with it be The gross weight of system generally up to tens kilograms of even more highs, because its quality is larger and arrangement of fixed position, for vehicle knot The influence of structure vibration characteristics is also larger.Irrational battery pack structure design can change body vibrations characteristic, vehicle has been occurred altogether Shake, cause deformation and the noise of car body, influence the NVH performances of vehicle, so, by the supporting construction of reasonably optimizing battery bag, Excited frequency is avoided, has highly important meaning for optimization body vibrations characteristic, lifting vehicle body first-order flexure mode.
In sum, how reasonably optimizing battery bag dependency structure, to ensure battery bag and vehicle body bonding strength, improve curved Bent modal frequency, is the current technical issues that need to address of those skilled in the art.
Accordingly, it would be desirable to one kind ensure that battery bag and vehicle body bonding strength, while shaking for battery bag generation can be reduced The battery bag longeron assembly of dynamic and noise.
Utility model content
In view of this, the purpose of this utility model is to provide one kind and ensure that battery bag and vehicle body bonding strength, while The vibration of battery bag generation and the battery bag longeron assembly of noise can be reduced;
Battery bag longeron assembly of the present utility model is included for supporting the longeron body of battery bag, being arranged at the longeron Body two ends are used to longitudinally carrying out along longeron the battery bag spacing locating part and are fixed on the longeron body bottom portion Support member for supporting the longeron body;The support member is provided with the installation position for being connected with vehicle frame;
Further, the longeron body is the bathtub construction of opening upwards;
Further, the top side wall outward flanging of the longeron body forms the platform for supporting battery bag;
Further, the locating part is the limiting plate for being fixed on longeron body end;
Further, the support member includes that it is the base plate of U-shaped structure and two side plates that can surround, and side plate wild card described in two is simultaneously The lateral wall of longeron body is fixed on, the installation position is the installation nut being fixed on the base plate;
Further, the support member is fixed by fastener with the side wall of longeron body, and the side plate of support member is provided with use In the bar hole for passing through fastener;
Further, described support member one end is fixed with the plate of the L-shaped for supporting longeron body bottom portion.
The beneficial effects of the utility model are:Battery bag longeron assembly of the present utility model, battery bag may be supported on longeron Carry out spacing on body and by the locating part at longeron body two ends, the support member below longeron body can be fixedly mounted on vehicle frame On, so as to realize interfixing for longeron and vehicle frame, battery bag longeron assembly of the present utility model ensure that battery bag and car Body bonding strength, while the vibration of battery bag generation and the battery bag longeron assembly of noise can be reduced.
Brief description of the drawings
Technical solutions of the utility model are further illustrated with reference to the accompanying drawings and examples:
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Fig. 1 is structural representation of the present utility model;As illustrated, the battery bag longeron assembly in the present embodiment includes using It is used to longitudinally carry out the battery bag along longeron in supporting the longeron body 3 of battery bag, being arranged at the two ends of longeron body 3 Spacing locating part and the bottom of longeron body 3 is fixed on for supporting the support member 6 of the longeron body 3;The branch Support member 6 is provided with the installation position for being connected with vehicle frame;The battery bag longeron assembly of the present embodiment, battery bag may be supported on longeron Carry out spacing on body 3 and by the locating part at the two ends of longeron body 3, the support member 6 of the lower section of longeron body 3 can be fixedly mounted on On vehicle frame, so as to realize interfixing for longeron and vehicle frame, battery bag longeron assembly of the present utility model ensure that battery bag With vehicle body bonding strength, while can reduce battery bag generation vibration and noise battery bag longeron assembly;
In the present embodiment, the longeron body 3 is the bathtub construction of opening upwards, the longeron body 3 of bathtub construction it is anti- Curved intensity is stronger, can carry out secure support to larger battery bag of conducting oneself with dignity.
In the present embodiment, the top side wall outward flanging 1 of the longeron body 3 forms the platform for supporting battery bag, The podium level formed on the two side of longeron body 3 is equal and in being generally aligned in the same plane, and the size of flange 1 is according to the big of battery bag Depending on small, to improve the stationarity that longeron body 3 is supported to battery bag;
