Description

Novel lithium battery module fixed bolster

Technical Field

The utility model belongs to the technical field of the battery installation, especially, relate to a novel lithium cell module fixed bolster.

Background

A lithium battery is a primary battery using a nonaqueous electrolyte solution with lithium metal or a lithium alloy as a negative electrode material. The lithium battery is used as an energy battery with high reaction efficiency, strong safety and small volume, and is more and more widely applied; the lithium battery has the advantages of small volume, light weight, high energy power, low self-discharge rate, environmental protection, long service life and the like, so that the lithium battery gradually becomes the mainstream of the power battery.

The battery pack of the electric automobile is formed by connecting a plurality of battery modules in series and parallel, so when the battery pack is assembled, the battery modules are required to be fixed together, the traditional method usually adopts adhesive tapes to bind and fix the modules to form the battery pack, the modules are easy to fall off in the mode, the heat dissipation performance is poor, the disassembly is time-consuming and labor-consuming, and the modules are easy to scrap.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem of the prior art, the utility model provides a novel lithium battery module fixed bolster, including the module frame, the module frame includes left side board and right side board, the top and the bottom side of left side board and right side board are fixed through the steel lath respectively, and it is fixed that layering or baffle are passed through to anterior and rear portion side, the battery module has been placed between left side board and the right side board.

Further, the lath that takes the kink of steel lath both sides bending type one-tenth cross-section is "C" type structure, the kink outwards buckles for battery module.

Further, the fixed bolster still includes outside box, the module frame is placed in the outside box, outside box is one side open-ended closed shell structure, and a side of outside box is recessed to form and dodges the portion, dodge and install battery module pin on the portion, left side board and right side board laminating the inner wall of outside box makes the module frame can't rock in the external box, leave the space between the rear portion side of module frame and the outside box inner wall, install the circuit protection shield in the space, the circuit protection shield is installed on the inner wall of outside box, the circuit protection shield passes through the wire and connects respectively battery module and battery module pin.

Furthermore, a cover plate is arranged at an opening of the external box body.

Further, the middle part of the steel strip plate is bent to form a reinforcing rib.

According to the technical solution provided by the utility model, the utility model has the advantages that: the utility model discloses a fixed lithium battery module of iron stand structure has overcome the defect that prior art adopted the sticky tape ligature mode to have for the battery contains quick detachable, and convenient maintenance or renewal part have good thermal diffusivity simultaneously, have improved the life of battery. In addition, the fixed bolster appearance design is reasonable, leaves the battery module pin and dodges the position, and the pin can not take up space and influence the installation during the installation.

Detailed Description

As shown in fig. 1 and 2, a novel lithium battery module fixing bracket for fixing a block-shaped lithium battery comprises a module frame 1, wherein the module frame comprises a left side plate 2 and a right side plate 3. The top and the bottom side of left side board 2 and right side board 3 are fixed through lath 4 respectively, and lath 4 detachably fixes at 3 borders on left side board 2 and right side board, for example can adopt the screw connection mode, convenient follow-up dismantlement equipment. The front and rear side edges are fixed by a baffle 5, and the baffle 5 and the left and right side plates 2 and 3 are also detachably fixed, for example, by screws. Placed battery module 6 between left side board 2 and the right side board 3, battery module 6 compresses tightly the range by a plurality of cubic lithium cell and forms. Wherein left side board 2, right side board 3, steel lath 4, baffle 5 all separate with battery module 6 through insulating cushion. In order to improve the anti bending property of lath 4, the lath of taking kink 7 that the both sides of lath 4 were buckled into the cross-section and be "C" type structure, the kink outwards buckles for the battery module. In order to further improve the bending resistance of the steel strip plate 4, a reinforcing rib can be formed in the middle of the steel strip plate by bending.

As shown in fig. 3, the fixing bracket further includes an external box 8, the module frame 1 is placed in the external box 8, the external box 8 is a closed shell structure with an opening on one side, and according to different requirements, a cover plate may be provided at the opening of the external box to prevent dust from entering, or the cover plate may not be provided, so as to improve heat dissipation. A side of the external box body is recessed inwards to form an avoiding part 9, and a battery module lead post 10 is installed on the avoiding part 9, so that the lead post 10 does not occupy space and influence installation when a battery pack is installed. Left side board 2 and the laminating of right side board 3 the inner wall of outside box makes the module frame can't rock in the outside box. A gap 11 is reserved between the rear side face of the module frame 1 and the inner wall of the outer box body 8, and a circuit protection plate 12 is installed in the gap 11 and used for preventing a battery pack from being burnt out due to current or voltage overload. The circuit protection board is mounted on the inner wall of the outer box 8. The circuit protection board 12 is connected to the battery module 6 and the battery module lead post 10 through a conductive wire, respectively.

The technical solution provided by the present invention has been described in detail, and to the general technical personnel in the field, according to the utility model discloses the thought of embodiment all has the change part on concrete implementation and application scope, to sum up, this description content should not be understood as right the utility model discloses a restriction.
