Technical field
The present invention relates to the electronlmobil field, the particularly integrated technology of electronlmobil is specifically related to the arrangement structure of the electrokinetic cell assembly of electronlmobil.
Background technology
Electronlmobil is as the representative of new-energy automobile, and its energy-saving and environmental protection, zero-emission, noise are little etc., and advantage is widely known by the people.But there are problems such as safety, reliability, insufficient driving range.In order to guarantee that electronlmobil in use has safety preferably and reliability, and the continual mileage that improves electronlmobil, just must be by rational layout, and increase the capacity and the volume of battery assembly as much as possible.Cause the installing space of electrokinetic cell assembly on car load very limited thus.
Because the orthodox car parts are numerous, body construction is fixed, and realize the rational deployment of electrokinetic cell assembly on existing vehicle, and the arrangement space of electrokinetic cell assembly is extremely limited.As: crossbeam that automobile fore suspension and rear suspension, left-right longeron, spare tyre and installation seat are used or the like.These important spare parts have all limited the available space that is used to arrange battery.If vehicle body is not carried out a large amount of modifications, be difficult to the electrokinetic cell assembly is reasonably arranged.
Existing hybrid vehicle or electronlmobil generally all adopt following several arrangements: what have is arranged in forward engine room with the electrokinetic cell assembly, what have is arranged in the baggage container position with the electrokinetic cell assembly, what have is arranged in the fuel tank position with the electrokinetic cell assembly, and what have is arranged in back seat position or the like with the electrokinetic cell assembly.These can cause car load front and back axle load skewness, deterioration of safety, and the battery thermal management inconvenience reduces shortcomings such as crew module space.
Summary of the invention
The invention provides a kind of arrangement structure of four-player seat electric automobile power battery assembly, solve the capacity of electrokinetic cell assembly and the contradiction of volume demand and arrangement space; The safety performance of electrokinetic cell assembly requires the problem with collision safety; The problem of the heat management system of electrokinetic cell assembly and in-use performance and cycle life; And vehicle body is improved the contradiction that reduces with ride comfort by the floor.
The arrangement structure of a kind of four-player seat electric automobile power battery assembly that the present invention proposes, be that the electrokinetic cell assembly is arranged in below the body platform, between left-right longeron, front and back axletree, described electrokinetic cell assembly occupies the position that fuel tank is placed in traditional fuel-engined vehicle arranging exhaust air pipe, noise silencer and below, back seat position.
Further, described electrokinetic cell assembly electrokinetic cell assembly, medium power battery assembly and back electrokinetic cell assembly are formed, preceding electrokinetic cell assembly and medium power battery assembly are positioned at the space that body platform is used to load freeing pipe, and back electrokinetic cell assembly is positioned at the space that is used to load fuel tank and noise silencer under the body platform.
Further again, the shape of the upper surface of electrokinetic cell assembly, medium power battery assembly and back electrokinetic cell assembly changes with the height and the longeron of body platform before described, the local electrokinetic cell assembly thickening of ground plate hight, the local electrokinetic cell assembly attenuation that the floor is low, the lower surface of electrokinetic cell assembly is in sustained height.
The arrangement structure that the present invention proposes is when guaranteeing gordian techniquies such as the distribution of car load axle load, collision safety, guarantee certain ground Clearance, spare tyre and trunk space, satisfy the maximization of capacity of cell and volume simultaneously, vehicle body is changed minimized target, has easy installation and removal, is artistically decorated, advantage such as convenient management.

The specific embodiment
Below in conjunction with compound detailed description the present invention:
The tradition fuel-engined vehicle is furnished with freeing pipe and noise silencer under the floor, fuel tank is placed in below, back seat position.And, do not have driving engine at four-player seat pure electric automobile, and do not need freeing pipe, noise silencer and fuel tank, in order to be utilized the space, increase battery assembly capacity and installation volume.Parts such as freeing pipe, noise silencer, fuel tank and mounting bracket thereof are cancelled, thereby can effectively utilize these spaces, when considering the distribution of car load axle load, satisfying collision safety, battery thermal management requirement and ride comfort, also satisfied the demand of electronlmobil, increased continual mileage capacity of cell.
After former traditional vehicle N/R part cancellation, arrange the electrokinetic cell assembly, original crew module, boot compartment and the spare tyre space of having kept in working order.
See figures.1.and.2, the vehicle 100 that the battery assembly that adopts embodiments of the invention to relate to is arranged describes.
In the following description, the electrokinetic cell assembly that is loaded into vehicle 100 not only can be a secondary battery, also can be fuel cell etc.; In addition, in the following description, constituting the battery of electrokinetic cell assembly, both can be any in lead-acid storage battery, lithium ion battery and the Ni-MH battery, also can be other batteries.Below, the method for arranging of secondary battery (lithium ion battery) is described.
