Abstract

The invention discloses a vehicle body of an electric vehicle, and relates to the technical field of automobile manufacturing. The vehicle body of the electric vehicle comprises a left front longitudinal beam, a right front longitudinal beam and a floor. A floor upper portion left reinforcing longitudinal beam and a floor upper portion right reinforcing longitudinal beam are arranged on the floor. The positions of front seats on the floor protrude upwards to reserve battery pack mounting space. The floor upper portion left reinforcing longitudinal beam and the floor upper portion right reinforcing longitudinal beam turn in the protruding positions and extend to a front seat left rear cross beam and a front seat right rear cross beam. A floor lower portion left reinforcing longitudinal beam and a floor lower portion right reinforcing longitudinal beam are arranged in the positions, corresponding to the floor upper portion left reinforcing longitudinal beam and the floor upper portion right reinforcing longitudinal beam, of the bottom face of the floor correspondingly and are connected with the left front longitudinal beam and the right front longitudinal beam correspondingly. A transverse reinforcing beam is arranged between the floor lower portion left reinforcing longitudinal beam and the floor lower portion right reinforcing longitudinal beam. According to the vehicle body of the electric vehicle, the wide and regular mounting space is provided for a battery pack of the electric vehicle, vehicle body deformation in collision of the electric vehicle is effectively reduced, and the safety of passengers and the battery pack is protected.

Description

Electric car body
Technical field
The present invention relates to field of automobile, be that the body structure installing and strengthening electric automobile collision security performance put by a kind of batteries of electric automobile infantees that is beneficial to.
Background technology
Traditional automobile body floor structure is generally divided into floor panel and floor frame, and this floor frame framework is by many crossbeams, and longeron forms, and the framework formed is substantially in same level, and for single layer structure, and this horizontal plane position ratio is relatively low.Electrokinetic cell is such as placed on below floor, road clearance will be abnormal little, as being placed on above floor, then battery bag is in crew module, cannot be effectively isolated with occupant, dangerous and to take bigger interior space, so the body platform of said structure cannot be directly used in electric automobile, the installation of electrokinetic cell can be affected.On the other hand, electric automobile complete vehicle weight after increasing battery bag substantially increases, and easily causes bigger body distortion when collision, directly threatens occupant and the safety of battery bag.
Summary of the invention
The technical problem to be solved is to provide a kind of electric car body, and it can solve batteries of electric automobile bag and be difficult to arrange the problem installed, and can effectively reduce the electric automobile body distortion when collision, protection occupant and battery bag safety.
In order to solve the problems referred to above, the technical scheme is that this electric car body includes left front girder and front right longitudinal beam and floor, above described floor, both sides are respectively arranged with top, the floor left longeron of reinforcement and right vertical beam is strengthened on top, floor, the indwelling that starts to raise up from front-row seats position of described floor has battery bag installing space, left longeron is strengthened on top, described floor and top, floor strengthen right vertical beam respectively after described high spot transfer and is extended to the left back crossbeam of front-row seats with the right rear cross beam of front-row seats；In bottom surface, described floor, left longeron and the position of top, floor reinforcement right vertical beam is strengthened corresponding to top, described floor, it is respectively arranged with bottom, floor and strengthens left longeron and bottom, floor reinforcement right vertical beam, and be connected with described left front girder and front right longitudinal beam respectively, strengthen left longeron in bottom, described floor and bottom, floor is strengthened between right vertical beam, corresponding to after the left back crossbeam of front-row seats and the position of the right rear cross beam of front-row seats, it is provided with horizontal buttress brace.
Owing to using technique scheme, there is advantages that
1, the present invention starts to raise up from front-row seats position, indwelling has battery bag installing space, in the case of not changing other regions of vehicle body, can be that battery bag provides spacious, regular installing space, be conducive to arranging large-capacity battery pack to increase electric motor car course continuation mileage；And this battery bag installing space and crew module can be effectively isolated, be conducive to improving the safety of occupant.
2, the present invention have employed the most double longeron and horizontal buttress brace structure in both sides, battery bag installation region; effectively strengthen bus body strength and rigidity; this structure carries out central collision at vehicle, biasing is touched or the panel beating deflection of vehicle body sheet metal especially battery bag installation region can be obviously reduced during side impact, to play protection occupant and the purpose of battery bag.Its advantage is simple in construction, and collision safety performance is obviously improved, and does not affect battery bag installing space.
Accompanying drawing explanation
Fig. 1 is the schematic top plan view of the present invention；
Fig. 2 is the elevational schematic view of the present invention.
In figure, label is expressed as: 1, floor, 2, left longeron is strengthened on top, floor, 3, right vertical beam is strengthened on top, floor, 4, the left back crossbeam of front-row seats, 5, the right rear cross beam of front-row seats, 6, bottom, floor strengthen left longeron, 7, right vertical beam is strengthened in bottom, floor, 8, left front girder, 9, front right longitudinal beam, 10, horizontal buttress brace.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
The electric car body of Fig. 1 and Fig. 2, including and floor 1 and left front girder 8 and front right longitudinal beam 9, floor 1 the right and left above is respectively arranged with top, floor and strengthens left longeron 2 and top, floor reinforcement right vertical beam 3, floor 1 indwelling that starts to raise up from front-row seats position has battery bag installing space, and left longeron 2 is strengthened on top, floor and left longeron 3 is strengthened respectively after described high spot is transferred and extended to the left back crossbeam of front-row seats 4 and the right rear cross beam of front-row seats 5 in top, floor；In bottom surface, floor 1, left longeron 2 and the position of the left longeron 3 of top, floor reinforcement is strengthened corresponding to top, floor, it is respectively arranged with bottom, floor and strengthens left longeron 6 and bottom, floor reinforcement right vertical beam 7, and be connected with left front girder 8 and front right longitudinal beam 9 respectively, portion strengthens left longeron 6 and bottom, floor is strengthened being provided with horizontal buttress brace 10 between right vertical beam 7 under floor.
The projection on floor 1 is that battery bag provides sufficient space, it is simple to be integrated under seat by battery bag.And left longeron 2 is strengthened on top, floor and right vertical beam 3 is strengthened on top, floor, bottom, floor strengthens left longeron 6 and right vertical beam 7 is strengthened in bottom, floor and horizontal buttress brace 10 then can be remarkably reinforced vehicle body bulk strength and rigidity；When collision, due to the booster action of these beams, the deflection of vehicle body can be obviously reduced, to reduce the occupant in collision and the infringement of battery bag.
