Abstract

The invention provides a method and a device for assembling power batteries in a square energy pack. In the invention, batteries are grouped with an even number, each group of batteries are assembled into a module by adopting an independent fixing device, and in each module, two batteries are assembled into a group to divide the batteries into a plurality of sub groups; the independent fixing devices are connected by four end plates to form a square box-shaped structure, a symmetrical position of a group of two symmetrical end plates is provided with a plurality of small ports, and the part of the small ports is provided with a partition plate; and every two batteries are put in each parallel interval divided by the partition plates. By adopting the invention, the modularization, the generalization and the standardization of the battery assembly can be realized, thus the invention is convenient for modularization assembly and maintenance; meanwhile, the batteries are reliably fixed, thus friction between the batteries can be effectively reduced.

Description

The assembly method and the device of square energy bag internally-powered battery

Technical field

The present invention relates to the assemble method and the device of battery, the assembly method and the device of particularly square energy bag internally-powered battery.

Background technology

Battery for no independent stationary position, existing energy bag mainly adopts the fixed form of clamping plate and pull bar, after battery-arrangements is placed, place high strength clamping plate respectively at the two ends of battery pack, lock with nut with pull bar between the two clamping plates and be connected, thereby make relative fixed between battery pack and clamping plate and the pull bar, the battery of this fixed form is mainly strained clamping plate by pull bar, thereby compress battery, reach the purpose that prevents the battery play by frictional force and screens between the battery, be subjected to the pressure size that battery bears and the difference of screw-down torque size, the box body size can not be fixed, operation or vibration the time can get loose, and be fixing unreliable, and dissimilar energy bag sizes is different and can not carry out the modularization assembling of reference format.

Summary of the invention

The present invention aims to provide a kind of assembly method and device of realizing battery load moduleization, generalization and standardized square energy bag internally-powered battery, and when being convenient to the scale installation and maintenance, battery is fixing reliable, can effectively reduce the friction between the battery.

The present invention realizes by following scheme: the assembly method of square energy bag internally-powered battery, with battery is the unit grouping with the even number, each Battery pack adopts independently that fixture is assembled into a module, with one group on two batteries battery is divided into some groups again in each module.

Normal conditions, in order to adapt to batch process, the number of batteries in each module is identical, and the independent stationary device of employing also just can use same size and size, and one is one to assemble that to be made into standalone module comparatively suitable with 10 batteries.

A kind of device of realizing the assembly method of square energy bag internally-powered battery, interconnect by some battery modules of the assembling of fixture independently and to be assembled into the energy bag, wherein independently fixture is connected to form the box-like structure that is square by four end plates, wherein have some osculums at the symmetric position place of two end plates of one group of symmetry, there is dividing plate at the osculum place, places two batteries between each parallel zone that is divided into by dividing plate.Be that an assembling is made into a module even, then just be divided between 5 parallel zones two batteries of interior placement between each parallel zone in each module by dividing plate with 10 batteries.

For preventing the battery bob, have fixing hole in symmetric positions of two end plates of another group symmetry of described independent stationary device, with fixture depression bar is being installed on the assemble and between these two end plates.

For ease of heat radiation and reduce friction between the battery, both sides end plate for the symmetry that has osculum of described independent stationary device, end plate has two rows position symmetry and the equal osculum of quantity on one side, there is small baffle at each osculum place, and the osculum of another side end plate and small baffle position are then symmetrical with it.Be to be made up by two dividing plates up and down of two dividing plates up and down of one side end plate and the symmetrical position of another side end plate between per two batteries to separate.

Than prior art, the present invention has the following advantages: 1. adopt assembly method of the present invention and device, battery is fixed with modularization, but fixture standardization, therefore battery module is by standardization, and the assembling of energy bag also just can realize modularization, standardization, is convenient to production control.

2. adopt this independent stationary device of the present invention, can disperse the active force of battery pack to the fixture two ends, avoid battery in motion process, two end plates to be applied excessive impulsive force, cause the end plate distortion, and the pull bar set bolt is loosening, reduce the play friction between the battery module, also force to divide equally the ventilation gap between battery simultaneously, be beneficial to Homogeneouslly-radiating.

Description of drawings

The individual module STRUCTURE DECOMPOSITION figure of Fig. 1: embodiment 1; The individual module schematic diagram of Fig. 2: embodiment 1; Fig. 3: by the schematic diagram that becomes the energy bag after four assemblings of module of embodiment 1.

Embodiment

Embodiment 1 is referring to Fig. 1, and independently the assembly of fixture comprises first member plate 1, end plate 2, right end plate 4, depression bar 5 and front end-plate 6.First member plate 1, end plate 2, right end plate 4 and front end-plate 6 welding form a battery fixed bin that is square.

Have on the front end-plate 6 two rankings put the symmetry osculum 8, be divided into two rows, above four, below four; At each osculum place dividing plate 9 is arranged all, totally eight; With the end plate 2 of front end-plate symmetry on also have two row's osculums 10, each osculum position of position and osculum 8 is symmetrical, and at each osculum place dividing plate 11 is arranged, the position of dividing plate 11 is also symmetrical with the upper spacer 9 of front end-plate.

By two dividing plates up and down of the symmetric position of every two dividing plates up and down of front end-plate 6 and end plate 2, combination is divided into some front and back parallel space with space in the battery fixed bin, places two electrokinetic cells 3 in each parallel space.

Four bolts hole 12 are arranged on first member plate 1 and right end plate 4 symmetrically, be fixed in two depression bars 5 between the end plate of the left and right sides and place on the battery 3 with bolt, to prevent the battery bob.

Adopt above-mentioned independent stationary device to assemble battery and promptly can be assembled into as shown in Figure 2 independently battery module 8.And then by four independently battery module 8 interconnect the electrokinetic cell energy bag 13 that is assembled at last as shown in Figure 4.
