The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, thereby the utility model provides a kind of battery box stop motion mechnism of eliminating case stop in realize in the gap between the case and outside frame in the battery box.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Batteries of electric automobile case stop motion mechnism comprises two assemblies of slide block assembly and pushing block, and one of them assembly is installed on the interior case of battery box, and another assembly is installed on the outside frame; Said slide block assembly comprises the slides in telescopic piece, and the slides in telescopic piece is provided with the cleat planes A that direction flexible with it forms the oblique angle, and pushing block is provided with the suitable cleat planes B with cleat planes A; Case and outside frame installation state in the battery box, cleat planes A and cleat planes B fit.
During use; Earlier slide block assembly and pushing block being installed in respectively in the battery box closes on the outside frame on the case; Again with case in the battery box by being conventionally loaded in the outside frame, along with case in the battery box is installed the process that phases in, cleat planes A contact the generation interference with cleat planes B by not touching; Force the slides in telescopic piece to produce moving of flexible direction, case is in place in battery box; Case and outside frame installation state in battery box; Structure that slide block assembly and pushing block form, it has filled up the gap between the case and outside frame in the battery box at thickness direction, in the time of can effectively stoping vehicle to rock; Bump in the battery box between case and the outside frame, the stability of assurance battery.
Preferably, the end cut mutually of said slides in telescopic piece and pushing block rounding separately; This structure design is in order to guarantee the smooth installation of case in the battery box.
Preferably, the angle of bevel of the flexible direction formation of said cleat planes A and slides in telescopic piece is 17 °～30 °.
As a kind of preferred structure, said sliding shoe assembly also comprises sliding bar and spring, and said slides in telescopic piece and spring housing are contained on the sliding bar, are respectively arranged with position limiting structure at the two ends of sliding bar, and length of spring compressed is between position limiting structure and slides in telescopic piece; This kind structure Design; The slides in telescopic piece can be done fore and aft motion along the sliding bar direction, because spring is in compressive state always, it can guarantee case and outside frame installation state in battery box; Cleat planes A and cleat planes B fit closely, can not produce free motion; Certainly this is a kind of structure, can also be designed to other structures, such as using the cylindricality elastomeric element to replace sliding bar and spring, equally can realize identical function.
Preferably, said pushing block has a right angle medial surface; During use, pushing block is installed in the battery box on the case, its right angle medial surface can be simultaneously with battery box in two flanked of case touch the assurance stable installation.
Beneficial effect: the batteries of electric automobile case stop motion mechnism that the utility model provides; Simple in structure, easy to use, be convenient to the maintenance; Can reliably eliminate the gap between interior case of battery box and the outside frame, avoid rocking of the interior case of battery box, guarantee the stability that battery uses.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the perspective view of the utility model;
Fig. 3 is the scheme drawing of a kind of preferred structure of the utility model;
Fig. 4 is the utility model mounting structure scheme drawing in actual use.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
As Fig. 1, shown in Figure 2 be batteries of electric automobile case stop motion mechnism, comprise the slide block assembly 1 that is installed on the outside frame 3, be installed in the pushing block 2 on the case 4 in the battery box; Said slide block assembly 1 comprises slides in telescopic piece 11, and slides in telescopic piece 11 is provided with the cleat planes A14 that direction flexible with it forms the oblique angle, and pushing block 2 is provided with the suitable cleat planes B21 with cleat planes A14; Case 4 and outside frame 3 installation states in the battery box, cleat planes A14 and cleat planes B21 fit.
In order to guarantee the smooth installation of case 4 in the battery box, the rounding separately in end that slides in telescopic piece 11 and pushing block 2 are cut mutually; The angle preferable range at said oblique angle is 17 °～30 °; In order to improve the stable installation property of case 4 in pushing block 2 and the battery box, at right angle medial surface of pushing block 2 inboard designs, this right angle medial surface can touch with interior two flanked of case of battery box simultaneously.
As shown in Figure 3; A kind of preferred structure for this case; In this structure, sliding shoe assembly 1 also comprises sliding bar 12 and spring 13, and said slides in telescopic piece 11 is sleeved on the sliding bar 12 with spring 13; Two ends at sliding bar 12 are respectively arranged with position limiting structure, and spring 13 is compressed between position limiting structure and the slides in telescopic piece 11; Sliding bar 12 is fixedly mounted on the outside frame 3.
The horizontal direction of arrow among Fig. 3 is the case 4 issuable directions of rocking in the battery box, and vertically the direction of arrow is the installation direction of case 4 in outside frame 3 in the battery box.
During use, earlier slide block assembly 1 is installed on the outside frame 3, makes the position limiting structure at sliding bar 12, sliding bar 12 two ends and outside frame 3 keep fixing, slides in telescopic piece 11 can carry out telescopic moving, spring 13 normal operation; Again with the right angle medial surface of pushing block 2 respectively with battery box in two sides of case 4 fix; Then case in the battery box 4 is put into outside frame 3 by conventional approach, with pushing block 2 movement therewith that case in the battery box 4 fixes, pushing block 2 is with after slides in telescopic piece 11 contacts; Drive slides in telescopic piece 11 motion together; Pushing block 2 is because of the 4 spacing stop motions of case in the battery box subsequently, and slides in telescopic piece 11 continues the bounce-back under the effect of the spring on the sliding bar 12 3 of motion back, just in time with pushing block 2 clampings; Gap in fully eliminating between case and the outside frame reaches the stop purpose; Constructional drawing during installation is as shown in Figure 4.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
