Abstract
The invention discloses a battery pack handle and a manufacturing method thereof. During manufacturing, the fixing piece on the handle assembly is firstly adhered or welded at the position of the prefabricated groove on the surface of the battery pack. And (3) winding 2 packing belts around the battery pack for one circle along the prefabricated groove on the surface of the battery pack, bending and wrapping the packing belts at the joint of the packing belts by using two fins at two ends of a first handle assembly, and then tightly pressing the packing belts, and welding or riveting for fixing. And a second or third handle assembly is arranged at the passing part of the two packing belts on the other surfaces of the battery pack and is welded or riveted for fixing. By adopting the invention, when the handle is pulled, the stress of the handle is transferred to the packing belt, thus solving the problem that the handle is too concentrated and easy to break when being directly arranged on the battery pack; while also increasing the structural strength of the entire battery pack.

Disclosure of Invention
The invention aims to solve the technical problem of providing a battery pack handle and a manufacturing method thereof.
The technical scheme of the invention is as follows: a handle of a battery pack comprises a packing belt and a handle assembly, wherein the handle assembly consists of fixing pieces, fins and a handle, and two fixing pieces are arranged at two ends of the handle; fins are arranged on two sides of the fixing piece; the packing belt penetrates through the groove reserved in the surface of the battery pack and surrounds the battery pack for a circle.
The battery pack handle is formed by sticking or welding a fixing sheet on the surface of a battery pack in advance at a preset groove fixing position; and 2 packing belts are pressed on the two fins of the fixing piece, a circle of packing belt is wound along the groove reserved on the surface of the battery pack, the two fins of the handle fixing piece are bent at the overlapped part of the two ends of the packing belt and are riveted or welded and fixed after the packing belt is wrapped by the two fins of the handle fixing piece.
The packing belt is made of a steel belt or a plastic steel belt.
The handle assembly is fixedly arranged on the surface of any battery pack through which the packing belt passes, and one or more handle assemblies are arranged on different surfaces of the battery pack by adopting the same method according to needs.
A manufacturing method of a battery pack handle comprises the following steps:
(1) Firstly, a fixing piece on the handle component is stuck or welded at a fixed position of a prefabricated groove on the surface of the battery pack.
(2) And (3) winding 2 packing belts around the battery pack for a circle along the prefabricated groove on the surface of the battery pack, bending and wrapping the two fins at the two ends of the first handle assembly at the joint of the packing belts to tightly press the packing belts, and then welding or riveting for fixing.
Furthermore, a second or third handle assembly is arranged at the passing position of the two packing belts on the other surfaces of the battery pack and is welded or riveted for fixing.
The invention has the beneficial effects that: by adopting the scheme of the invention, when the handle is lifted, the stress of the handle is transferred to the packing belt, so that the problem that the handle is directly arranged on the battery pack, is too concentrated in stress and is easy to break is solved;
through two packing belts, tighten up the battery box body and upper and lower bottom, alleviateed the atress of battery box body and upper and lower bottom connecting piece or screw, increased the structural strength of whole battery package.
