Embodiment
In order to make those skilled in the art person understand the present invention program better, below in conjunction with drawings and embodiments, the present invention is described in further detail.
See Fig. 1 to Fig. 3, the invention provides a kind of Battery case and bracket jockey of three-dimensional position constraint, comprise bracket 8 and casing bottom girder 2, described bracket 8 is fixedly connected with by multiple bolt 10 with battery flat base plate 5, and described battery flat base plate 5 is fixedly connected with needing the automobile installed.
In specific implementation, described bracket 8 is not limited to be connected with described battery flat base plate 5, can also, with the automobile body bottom plate needing to install, certainly the automobile component installed can also be needed to be connected with other.
In the present invention, described bracket 8 is frame-type girder construction, and the upper lateral interval of described bracket 8 is provided with four row's rollers 14.Described casing bottom girder 2 is the gate mount structure that can improve casing intensity.
In the present invention, see Fig. 2, described casing bottom girder 2 welds together with Battery case 1, is placed with battery module in described Battery case 1.
In the present invention, bottom described Battery case 1, there is track 15, shape, the corresponding coupling of size of the shape of described track 15, size and described roller 14, therefore, for the present invention, described Battery case 1, under the guiding of described track 15 and the support of bracket 8 upper roller 14 coordinate, can be installed on bracket 8 easily.
In the present invention, the left end of described casing bottom girder 2 is provided with taper pin 12, and the right-hand member of described casing bottom girder 2 is provided with casing bottom girder tapered sleeve 4;
The position that the left end of described bracket 8 is corresponding with described taper pin 12 is provided with bracket tapered sleeve 13, the position that the right-hand member of described bracket 8 is corresponding with described casing bottom girder tapered sleeve 4 is provided with bracket thread bush 3;
In the present invention, shape, the size Corresponding matching of the shape of described bracket tapered sleeve 13, size and described taper pin 12, therefore, when casing bottom girder 2 turn left mobile to the end time, described taper pin 12 is inserted in bracket tapered sleeve 13, forms taper seat and coordinate between described taper pin 12 with described bracket tapered sleeve 13.
In specific implementation, lock-screw 6 is threaded with described bracket thread bush 3 mutually through after movable tapered sleeve 7, casing bottom girder tapered sleeve 4 successively, namely described movable tapered sleeve 7 is enclosed within lock-screw 6, lock-screw 6 screw in be fastened to bracket thread bush 3 time, namely realize connection between Battery case 1 and bracket 8 and fastening.
In the present invention, described bracket 8 is connected with the three-dimensional position constraint of casing bottom girder 2 and is realized by following structure: when Battery case 1 pushes bracket 8 along the roller 14 on bracket, the taper pin 12 making to be welded on inside casing bottom girder 2 left end realizes taper seat with the bracket tapered sleeve 13 be welded on bracket 8 left end and coordinates;
Casing bottom girder tapered sleeve 4 is welded with on outside described casing bottom girder 2 right-hand member, bracket thread bush 3 is welded with outside the right-hand member of bracket 8, the movable internal diameter of tapered sleeve 7 coordinates with the non-threaded axle journal place of lock-screw 6, movable tapered sleeve 7 male cone (strobilus masculinus) with casing bottom girder tapered sleeve 4 for taper seat coordinates, therefore, when lock-screw 6 screws in bracket thread bush 3, the cone match of movable tapered sleeve 7 and casing bottom girder tapered sleeve 4 can be made, continue screw-in to prescribed torque and can realize fastening.
In the present invention, see Fig. 2, described bracket 8 and battery flat base plate 5 or need the automobile body bottom plate etc. installed to need to install automobile component between be fixedly connected with for screw thread;
In specific implementation, before and after the bottom of described bracket 8, both sides are distributed with three bolts 10 in lateral separation respectively, and described battery flat base plate 5 is provided with three welded nuts matched with described bolt 10 with described bolt 10 corresponding position.
In specific implementation, described bolt 10 is threaded with the welded nut on described battery flat base plate 5 mutually through insulating case 11, beam 9 successively.
In specific implementation, described insulating case 11 is preferably and adopts resin material to make, and can realize the insulation between battery flat base plate 5 and bracket 8 like this;
In the present invention, in specific implementation, see Fig. 2, during in order to ensure to be connected between bracket 8 with described battery flat base plate 5, have damping effect and can eliminate the foozle connecting plane, be provided with beam 9, described beam 9 is positioned on the position between described bolt 10 head (namely towards one end of Battery case 1) and battery flat base plate 5, beam 9 can reduce the shock loading from road vertical direction, eliminates and connects interplanar foozle.
In specific implementation, before and after the bottom of described bracket 8, lower plane lateral separation, both sides is distributed with three through holes, and described through hole is corresponding with described bolt 10 to be arranged, and the aperture of described through hole coordinates with the internal diameter of beam 9 and the outside dimension of insulating case 11.
Therefore, for Battery case and the bracket jockey of three-dimensional position constraint provided by the invention, it has the function that insulation, damping and compensation are connected plane machining error.
It should be noted that, for Battery case and the bracket jockey of three-dimensional position constraint provided by the invention, it when mounted, first, be welded on the Battery case 1 on described casing bottom girder 2, under described four guiding of arranging rollers 14 and track 15 coordinate, slip of turning left from the right side pushes, and finally makes the taper pin 12 on the left of casing bottom girder 2 and the bracket tapered sleeve 13 on the left of bracket 8 plug cooperation.Then, by lock-screw 6 insertion activity tapered sleeve 7, again the lock-screw 6 that movable tapered sleeve 7 is housed is screwed in the bracket thread bush 3 on bracket 8, in screw-in process, progressively make inside and outside two to record taper seat laminating and realize location, continuing to screw in lock-screw 6 to prescribed torque can realize fastening, and these work all complete at the Battery case of handled easily and the outside of bracket.
It should be noted that, progressively screw in lock-screw 6, the taper seat of inside and outside both sides is fitted and realizes being positioned in the connection fastener cycle of prescribed torque, beam 9 axial deformation makes assembling be more convenient for.
Therefore, the present invention can realize Battery case (or battery system) Fast Installation on battery flat base plate or body of a motor car, and realize reliable position constraint in X, Y, Z tri-directions, there is the function of plane machining error of damping, insulation, balancing battery Ceiling simultaneously, greatly can improve the safety and reliability of battery module (or battery system).
In sum, compared with prior art, the invention provides a kind of Battery case and bracket jockey of three-dimensional position constraint, it can realize in X, Y, Z tri-directions carrying out reliable position constraint and fastening reliably to battery module, realize connecting, insulating and damping between bracket and battery flat base plate or automobile body bottom plate, improve the ability that battery module bears vibration and shock loading, ensure that the use safety of battery module, be conducive to applying widely, be of great practical significance.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
