Description

A kind of pin-connected panel battery bag casing
Technical field
The utility model is related to electrokinetic cell field, more particularly to a kind of pin-connected panel battery bag casing.
Background technology
Battery bag is the important power source of electric automobile, the device that battery bag casing is deposited and protected as battery bag, case The anti-extrusion ability of body, collision resistance are required for paying special attention to, because different battery bag size weight is differed, its battery core Assembling mode can also have nothing in common with each other, and some battery bags need the polycrystalline substance of battery bag casing to strengthen, and some battery bags are then needed Casing or so side structural strengthening or front and rear side structure is wanted to strengthen, but battery bag casing is generally monoblock cast shaping or is drawn into Type, shape of product is single.If in order to realize some strength and anti-extrusion ability of casing, each face of casing all thickened Words, whole box weight will be very big, it has not been convenient to transport and cost is also high;If will be according to actual conditions, by increasing Certain face of casing or the thickness in some faces are come if meeting the intensity requirement of casing, it is necessary to which large complicated many molds are Can realize, such casing manufacturing process is complicated, cost is also high.
Utility model content
Regarding to the issue above, the utility model provides a kind of pin-connected panel battery bag casing, including square base plate, around Base plate top and the front side board vertical with base plate, back side panel, left plate, right plate;The front side board, back side panel are individually fixed in Two sides long of base plate, the left plate, right plate are individually fixed in two short sides of base plate;The side edge long of the base plate sets Have multiple bottom holes, the lower end of the front side board and back side panel be all provided with oriented base plate inner side direction extend and with bottom hole pair The multiple protuberances answered, the protuberance is provided with side plate through-hole corresponding with bottom hole, can be by bottom hole and side plate Through hole realizes the bolt connection of front side board, back side panel and base plate.
Preferably, the front side board, be welded and fixed between back side panel, left plate, right plate.
Preferably, the base plate and front side board, back side panel, left plate(4), right plate(5)Between fixed with brazing mode Connection.
Preferably, a plurality of reinforcement parallel with base plate side long is provided with the base plate.
Preferably, the thickness difference of the base plate, front side board, back side panel, left plate, right plate.
Preferably, the front side board, back side panel, left plate, right plate upper end are provided with to the outer of plate outer side direction extension Flange, the outward flange is provided with multiple cover plate mounting holes.
Preferably, the base plate edge is provided with the base flanges for stretching out, and the base flanges are provided with multiple base plates Mounting hole.
The pin-connected panel battery bag casing that the utility model is provided, due to using assembled structure, therefore can be for actual Situation meets the intensity requirement to casing using the plate of different-thickness, and intensity requirement face high uses thicker plate, and intensity will Ask low face to use relatively thin plate, the overall weight of casing, and manufacturing process can be reduced on the premise of intensity requirement is met Simply, low cost.And fixed using first coordinating through hole to position with bolt, then the mode of Welding ensures between side plate and base plate Installation site is accurate, is connected firmly.
Brief description of the drawings
Fig. 1 is the pin-connected panel battery bag casing example structure figure that the utility model is provided.
Fig. 2 is Fig. 1 embodiment base arrangement figures.
Fig. 3 is lateral plate structure figure before and after Fig. 1 embodiments.
Fig. 4 is Fig. 1 embodiment left side plate structure charts.
Specific embodiment
The utility model is better understood from for ease of those skilled in the art, is carried out below in conjunction with the accompanying drawings further It is bright.
Pin-connected panel battery bag casing as shown in Figure 1,2,3, 4, including square base plate 1, around the top of base plate 1 and with bottom The vertical front side board 2 of plate 1, back side panel 3, left plate 4, right plate 5;Between front side board 2, back side panel 3, left plate 4, right plate 5 By being welded and fixed.
The side edge long of base plate 1 is provided with multiple bottom holes 11, and the lower end of front side board 2 and back side panel 3 is all provided with oriented base plate Inner side direction extends and multiple protuberances 6 corresponding with bottom hole 11, and the protuberance 6 is provided with corresponding with bottom hole 11 Side plate through-hole 61, by the cooperation of bottom hole 11, side plate through-hole 61 and bolt, be capable of achieving front side board 2, back side panel 3 and bottom After the fixation of plate 1, base plate 1 and front side board 2, back side panel 3 are beforehand through bolt stationary positioned, then reinforced using Welding, from And front side board 2, back side panel 3 are individually fixed in two sides long of base plate 1, it is to avoid because of front side board 2, rear side when directly being welded Welding position deviation between plate 3 and base plate 1 causes inventory disposal.Soldering is fixed on the two of base plate 1 respectively for left plate 4, right plate 5 Bar short side, due to being welded and fixed between left plate 4, right plate 5 and front side board 2, back side panel 3, therefore is positioned, no indirectly Need to be positioned using bolt in advance.
Because the battery bag casing of the utility model offer is by base plate 1, front side board 2, back side panel 3, left plate 4, right plate 5 It is assembled into, therefore each several part can be designed as different thickness according to actual strength requirement, it is ensured that mitigate whole while intensity requirement Body weight.
Because base plate 1 directly carries battery bag, therefore to increase the intensity of base plate 1, can be set a plurality of flat with the side long of base plate 1 Capable reinforcement 12.
Front side board 2, back side panel 3, left plate 4, the upper end of right plate 5 are provided with the outward flange 7 extended to the lateral direction of base plate 1, The outward flange 7 is provided with multiple cover plate mounting holes 71 for installing battery bag.
