Embodiment
The practical implementation of the electrokinetic cell box assembly of the utility model is Fig. 1 ~ shown in Figure 5 for example, and this battery case mainly is made up of battery case 100 and battery compartment 200, and the slip pull cooperates between battery case 100 and the battery compartment 200.The frame that the base of battery compartment 200 encloses around comprising and along the vertical beam 202 between relative two frames that sets firmly of the pull direction spaced and parallel of battery case 100; In the present embodiment; This vertical beam 202 adopts in pairs and is provided with; Each vertical beam 202 surrounds opening U-lag structure up by steel plate, and like Fig. 4, shown in Figure 5, its lengthwise bearing of trend offers paired draw-in groove 204 side by side in cell wall upper edge, the both sides of each vertical beam 202; In the draw-in groove 204 of vertical beam 202 both sides, be installed with BOGEY WHEEL 2 through wheel shaft 1, and the vertical beam on corresponding each battery compartment 200 on the bottom surface of battery case 100 corresponding be provided with the gathering sill 101 that rolls and cooperate with BOGEY WHEEL 2.Wherein, Wheel shaft 1 comprises the central shaft 11 that axially is arranged in BOGEY WHEEL 2 centers; Central shaft 11 1 end ends radially convex with the convex edge 13,14 that cooperates with the inside and outside wall block of corresponding cell wall; Radially convex with the retaining that cooperates with BOGEY WHEEL 2 limit blocks near the outer peripheral face at middle part at central shaft 11 along 12; Be set with this retaining at the other end of central shaft 11 and cooperate the axle sleeve 15 that BOGEY WHEEL 2 is clamped the location along 12, also radially convex with the convex edge 16,17 with corresponding cell wall internal face block cooperation away from the far-end of BOGEY WHEEL 2 at axle sleeve 15.The BOGEY WHEEL 2 main bearings 21 that adopt are as its center framework; The external diameter of the internal diameter of bearing 21 and central shaft 11 adopts interference fit; Thereby be convenient to the installation of bearing 21; For guaranteeing in use to reduce wearing and tearing, on the circumferential exterior surface of bearing 21, be coated with the coating layer 22 that constitutes by super polyurethane material through injection moulding processing to battery case 100 bottom enamelled coatings.The super polyurethane material of bearing 21 peripheries are low with hardness, flexible coats, and it has wear-resisting characteristic, can guarantee its useful life under adverse circumstances, and the noise can reduce work the time.The gathering sill 101 of the width of the coating layer 22 of this super polyurethane material and battery case 100 bottoms is adaptive, thereby battery case 100 is played guide effect.
During installation; Central shaft 11 is penetrated in the bearing 21 of BOGEY WHEEL 2; Simultaneously; Put on axle sleeve 15 from the other end of central shaft 11, the retaining through central shaft 11 middle parts cooperates with axle sleeve 15 BOGEY WHEEL 2 clamped along 13 and is fixed on central shaft 11 middle parts, then central shaft 11 and axle sleeve 15 is snapped on the vertical beam 202 in the corresponding draw-in groove of offering 204 simultaneously.This mounting structure has been cancelled the fastening mode of screw commonly used, and is easy to assembly, and motion can improve the efficiency of assembling of battery case assembly flexibly greatly.Deviate from from draw-in groove 204 for preventing BOGEY WHEEL 2; In the present embodiment; The corresponding draw-in groove of offering 204 can adopt rectangular channel or circular recess on the vertical beam 204, and the width of the port part of this draw-in groove 204 is slightly less than the diameter of axle sleeve 15 and central shaft 11 corresponding wedging positions, and is as shown in Figure 5; So when mounted need be with certain pressure with axle sleeve 15 and central shaft 11 by advancing in the draw-in groove 204; Utilize the port of draw-in groove 204 to guarantee will can not deviate under axle sleeve 15 and central shaft 11 are in working order, this project organization is simple, easy for installation, has improved the dependability of battery case assembly.
In practical application, because the battery case overall weight is heavier, the about 300kg of some battery case weight; Consider battery case in circular flow, can have difference in height between the different battery compartments, thereby make indivedual bearings can bear bigger impact and local top load; Two platforms also can exist axis not parallel simultaneously, make bearing can bear certain axial load, so in the present embodiment; Select deep groove ball bearing for use in the BOGEY WHEEL 2; Thereby make radially load-bearing 100 kg of each bearing, and can bear certain axial load, and have sealing.Simultaneously, for guaranteeing the adhesion of bearing and external packets coating, the circumferential outer rim of each bearing all processes twice groove 23 through turning, and two bearings are used in combination side by side in each BOGEY WHEEL 2.
The frame that the base of the battery compartment 200 of the utility model encloses around comprising and along the vertical beam 202 that is provided with between relative two frames, in pairs that sets firmly of the pull direction spaced and parallel of battery case 100; Each vertical beam 202 upper edge its longitudinally wheel shaft that passes through at interval is rotatably equipped with BOGEY WHEEL 2; Its concrete mounting structure is existing in the above-described embodiments to be described in detail, repeats no more here.
