Description

Battery module pressurization anchor clamps

Technical Field

The utility model relates to a battery module manufacturing technical field especially relates to a battery module pressurization anchor clamps.

Background

As a core component of a new energy automobile, the production of a power battery pack has received more and more attention in recent years. The power battery pack mainly comprises a module, a battery management system and other electric mechanical devices, and the size of the module significantly influences the internal space and subsequent assembly of the battery pack, so that the width of the module is strictly controlled during production. The module production includes the equipment and the welding of battery, end plate, curb plate and integrated apron, and wherein, the laminating compactness of curb plate and electric core side will directly influence the module width. The existing solution is to bond the side plates and the cells together by structural glue to control the dimensions. However, the process has a certain disadvantage that the module needs to be kept still for several hours after the glue is applied, so that continuous operation cannot be realized, and the production efficiency is seriously influenced. In the curing process, no pressurizer exists, tight fitting between the side plates and the batteries cannot be guaranteed, the width of the module is poor, and assembly of subsequent battery packs is affected.

Detailed Description

Referring to fig. 1-5, the utility model provides a battery module pressurization anchor clamps, including connecting plate 1, the interval is connected with a plurality of U type supports on the connecting plate 1, and U type support includes the bottom plate 2 of being connected perpendicularly with connecting

plate

1, and 2 both ends of bottom plate are connected with first curb plate 3, second curb plate 4 respectively perpendicularly, and bottom plate 2 passes through with the equal circular arc of first curb plate 3, second curb plate 4 junction. The first side plate 3 and the second side plate 4 are located on the same side of the bottom plate 2, and the inner sides of the first side plate 3 and the second side plate 4 are respectively connected with a first cushion pad 5 and a second cushion pad 6 through bolts.

In a specific embodiment, the middle part of the bottom plate 2 is provided with a wedge-shaped clamping groove 7, the connecting plate 1 is clamped in the wedge-shaped clamping groove 7, and the thickness of the connecting plate 1 is consistent with the depth of the wedge-shaped clamping groove 7.

In a specific embodiment, a first chamfer 8 is arranged at one end of the first buffer pad 5 away from the connecting plate 1, and a second chamfer 9 is arranged at one end of the second buffer pad 6 away from the connecting plate 1. The restraint space that the module can imbed U type support smoothly and form is guaranteed. First blotter 5, second blotter 6 can adopt silica gel, rubber etc. to have elastic material to do not by the fish tail when guaranteeing that the module curb plate puts into anchor clamps.

The utility model discloses 1 length of connecting plate keeps unanimous with module actual length, can customize the connecting plate 1 of different length according to module actual length. The width between first blotter 5, the second blotter 6 slightly is less than the actual width of module to guarantee that the module can continuously keep the extrusion state in embedding U type support. The vertical distance from the top of the first cushion pad 5 and the second cushion pad 6 to the connecting plate 1 is not higher than the actual height of the module.
