Jar frame for truck

Abstract

A jar for a truck is used for placing all truck jars. An upper-layer frame is fixed on a main body bracket; a side plate is welded on the main body bracket; a ball-type slideway is fixed on the main body bracket; holes are uniformly distributed in the slideway; balls are mounted in the holes through plugs; a movable baseplate is in contact with the balls directly; the movable baseplate is fixed with a movable baseplate bracket; the movable baseplate is fixed on a front fixed bracket through a bolt I; a guide sleeve is fixed at the bottom of the movable baseplate; a guide rod passes through holes on the front fixed bracket and a rear fixed bracket, which are arranged at two ends of the bottom of the movable baseplate, and the guide sleeve; and the guide rod is fixed on the front fixed bracket and the rear fixed bracket by a bolt II. The integral function is optimized, the weight is reduced by 4.5 kg as compared with an original double-layered jar frame, the size is smaller and the appearance is more attractive, a bearing, a mechanism and a connecting bolt nut in the original scheme are removed, the slideway adopts a ball-type, the sideway and a guiding mechanism are optimized to lower the cost to the great extent, and the guiding mechanism causes the movable baseplate to slide more stably without generating noise.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a storage battery frame used for storing storage batteries in trucks. Background technique [0002] Such as Figure 7 As shown, although the existing double-deck truck battery frame is compact in structure and beautiful in appearance, it still has the following defects: [0003] 1. The battery frame is bulky, which is not conducive to the lightweight requirements of the truck; [0004] 2. The cost of the battery frame is higher than that of the ordinary single-layer battery frame: the mechanism 15 is heavy, and the heavy double-layer shape makes the material cost higher than that of the ordinary single-layer battery frame; [0005] 3. The guiding device does not play an obvious guiding role, and the movable bottom plate is easy to shake left and right when it is pulled, and the noise is large; [0006] 4. After the mechanism 15 is laid flat, there is a transiti...

AI Technical Summary

Problems solved by technology

[0003] 1. The battery frame is bulky, which is not conducive to the lightweight requirements of the truck;

[0004] 2. The cost of the battery frame is higher than that of the ordinary single-layer battery frame: the mechanism 15 is heavy, and the heavy double-layer shape makes the material cost higher than that of the ordinary single-layer battery frame;

[0005] 3. The guiding device does not play an obvious guiding role, and the movable bottom plate is easy to shake left and right when it is pulled, and the noise is large;

[0006] 4. After the mechanism 15 is laid flat, there is a transition between the connection with the main body of the battery frame. During the drawing process of the movable bottom plate, when passing through this transition, the sliding is not smooth and there is a lot of noise;

[0007] 5. Twelve bearings are used as the sliding mechanism of the movable floor in the prior art, and the bearings need to be connected to the main body of the battery frame with twelve sets of standard bolts and nuts, which is costly;

[0008] 6. Mechanism 15 is connected to the main body through multiple connecting bolts and nuts, which is inconvenient to install and slide
