Description

Technical Field

[0001] This utility model relates to the field of battery installation technology, specifically to a battery bracket structure. Background Technology

[0002] A battery bracket, also known as a battery mounting bracket, is a device used to secure lithium batteries. Lithium battery brackets are typically made of aluminum alloy. Their design varies depending on the type of lithium battery and the application scenario. The main components include a positive electrode bracket, a negative electrode bracket, connectors, and cables. Mounting methods include patch mounting, side mounting, and vertical mounting to suit different application needs.

[0003] However, the existing technology has the following drawbacks:

[0004] When installing battery packs, existing battery mounting brackets place adjacent batteries close together. In harsh environments, these batteries are prone to squeezing and collision, which can damage them, cause leakage and pose safety hazards. In addition, some batteries are not securely installed and are prone to shaking. Utility Model Content

[0005] The purpose of this invention is to provide a battery support structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a battery bracket structure, comprising two outer shells, each outer shell having an installation cavity inside which a battery body is installed, the back of the battery body being tightly abutted against the inner wall of the back of the outer shell, the front of the battery body being covered with a limiting plate, the bottom of one side of the limiting plate and one side of the bottom being fixedly connected to the outer shell by a first fixing member and a second fixing member respectively, and the backs of the two outer shells being tightly abutted against each other.

[0007] The above technical solution involves two outer shells arranged opposite each other and back-to-back to isolate the two battery bodies, providing insulation, while the limiting plate provides a fixing and limiting function.

[0008] The outer shell is a rectangular shell with an open front and is made of aluminum alloy. The inner walls of the mounting cavity are all bonded with rubber pads. Several grooves are evenly distributed on the back of the outer shell. Several partitions are evenly distributed on the inner side of the outer shell, and the partitions are located between two adjacent grooves. Connecting posts are provided at one end of each side of the outer shell near the opening.

[0009] Using the above technical solution, the rubber pad provides cushioning and protection for the battery body, the groove prevents pressure between the battery cells when they bulge, and the separator acts as an isolation to prevent contact between the battery cell bodies.

[0010] Several pads are evenly provided on one side of both ends of the back of the outer shell, and two threaded through holes are evenly provided on the other side of both ends of the back of the outer shell. Bolts are threadedly installed in the two opposite threaded through holes, and fastening nuts are threadedly installed at the ends of the bolts. The pads are cylindrical and made of rubber.

[0011] The above technical solution connects the two outer shells with bolts through two opposite threaded holes, and the two opposite pads fit tightly together, leaving a gap between the two outer shells to facilitate ventilation and heat dissipation.

[0012] The width of the battery body is smaller than the width of the mounting cavity. The battery body is snapped into the inside of the mounting cavity. There are several protruding strips evenly distributed on both ends of the side of the battery body near the opening of the mounting cavity. A third fixing member is snapped into the front of two adjacent protruding strips.

[0013] The above technical solution has a rectangular cross-sectional shape for the protruding strip and a U-shaped frame with protruding plates on both sides for fixing the limiting plate and the battery body.

[0014] The limiting plate has several rectangular second through holes evenly opened at both ends. The second through holes are correspondingly arranged with the convex strip body and the convex strip body is inserted into the second through hole. The third fixing member covers the front of the convex strip body on both sides and the two are fixedly connected by screws. The top and bottom of the limiting plate have several first through holes evenly opened, and the middle part of the limiting plate has several elliptical holes evenly opened.

[0015] Using the above technical solution, both the first through hole and the elliptical hole serve the function of ventilation and heat dissipation, and the first through hole on both sides of the limiting plate is designed with side openings.

[0016] The outer casing has a first slot and a second slot on both sides from top to bottom. The first fixing member is an L-shaped plate and is fitted into the second slot. One side of the first fixing member covers the surface of the protruding strip on the bottom side of the front of the battery body, and the two are fixedly connected by screws.

[0017] In the above technical solution, one side plate of the first fixing plate is fixedly connected to one side of the outer casing, and the other side plate is fixedly connected to the front of the battery body.

[0018] The bottom of the outer casing is provided with a third slot on both sides. The bottom of the second fixing member is engaged and installed inside the third slot. The top of the second fixing member is covered on the surface of the protruding strip on the other side of the bottom front of the battery body, and the two are fixedly connected by screws.

[0019] Using the above technical solution, the second fixing component securely connects the battery body to the outer casing, and the cross-sectional shape of the second fixing component is L-shaped.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This utility model fixes the battery inside the outer casing, and then connects the two outer casings back to back, which isolates and insulates the battery. A limiting plate is provided on the front of the battery, which fixes and limits the battery to prevent it from falling off. Multiple ventilation holes are provided on the limiting plate and the outer casing to facilitate ventilation and heat dissipation. Attached Figure Description
