Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, and more specifically, to a handle for stacking and fixing battery packs. Background Art

[0002] In the market, a single battery pack cannot meet a family's daily electricity consumption. In existing technologies, people stack multiple battery packs and then use external connecting plates to connect and fix the upper and lower packs. The disadvantage of this fixing method is that the position accuracy error in the stacking assembly is large, which increases the complexity of installation and the external protrusion affects the appearance.

[0003] When the battery pack weighs more than 40 kg, the plastic handle can no longer withstand the weight. Forcibly pulling it up can easily cause the plastic handle to break. The current carbon steel handle is fixed with screws, which is time-consuming to install, has a prominent appearance, cannot achieve product integration, and is costly. Therefore, it is necessary to develop a handle for stacking and securing battery packs. Utility Model Content

[0004] The purpose of the utility model is to provide a handle for stacking and fixing battery packs.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A handle for stacking and fixing battery packs comprises a handle body 1. The handle body 1 is arranged on both sides of a product chassis, and the handle body 1 is a structure concave toward the product chassis.

[0007] Furthermore, a protrusion is provided in the structure concave toward the product chassis, and the protrusion corresponds to the place where the palm bears weight, and the protrusion is flush with the place where the palm bears weight.

[0008] Furthermore, a circular through hole is provided at the bottom of the structure concave toward the product chassis.

[0009] Furthermore, it also includes screws and rivets. When the battery packs are stacked, the screws pass through the circular through holes below the handle body and engage with the rivets on the lower product chassis cover.

[0010] Furthermore, the handle body 1 is made of the same sheet metal as the product chassis.

[0011] Furthermore, the handle body 1 and the product chassis adopt an integrated structure, and the handle body 1 is formed by bending sheet metal multiple times and then welding it to the product chassis.

[0012] Compared with the prior art, the advantages of the present invention are: the present invention adopts a semi-hidden fixing method, which reduces the complexity of installing the connecting piece on the outside of the battery pack, improves the appearance, improves the positioning accuracy, and reasonably reduces the cost.

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0020] See Figure 1-Figure 4 As shown, the present invention provides a handle for stacking and fixing battery packs, comprising a handle body 1. The handle body 1 is arranged on both sides of a product chassis, and the handle body 1 is a structure concave toward the product chassis.

[0021] Among them, the structure concave into the product chassis is provided with a protrusion, forming a shape that fits the human palm, the protrusion corresponds to the weight-bearing part of the palm, and the protrusion is flat with the weight-bearing part of the palm, and the part that fits the palm curvature is semicircular, which is more in line with the palm curvature principle, increases the force-bearing area, reduces the single-area pressure, and reserves sufficient space at the part that fits the fingers. The overall shape is similar to a semicircle, and then the handle is perfectly welded to the chassis. To ensure the appearance, it needs to be fully welded, polished, and powder-sprayed together with the chassis to make the handle and the chassis completely integrated, so that the handle's bearing capacity is maximized.

[0022] A circular through hole 4 is provided at the bottom of the structure concave toward the product chassis, which is formed during laser cutting of the handle.

[0023] The present invention also includes screws 2 and rivets 3. When the battery packs are stacked, the screws (M5X30) pass through the circular through holes below the handle body and engage with the rivets (M5) on the cover of the product chassis below. The upper and lower fixing screws are perfectly semi-hidden on the basis of the integrated handle, thereby improving the performance and beautifying the product appearance.

[0024] The material of the handle body 1 is the same sheet metal as that of the product chassis, which can be SPCC, SGCC, A6061, SUS301, etc.

[0025] The handle body 1 and the product chassis adopt an integrated structure. The handle body 1 is formed by bending sheet metal multiple times and then welding it to the product chassis.

[0026] Compared with traditional plastic handles, stainless steel handles, etc., the handle of this utility model has lower raw material costs and a simpler processing technology. Some processes are carried out simultaneously with the chassis, which reduces processing costs. The handle is integrated with the product chassis, which improves the aesthetics of the product, reduces the overall size, takes up less packaging space, reduces transportation costs, reduces the number of product parts (connecting pieces), reduces installation steps, improves installation efficiency, and is more firmly fixed than traditional connecting pieces.

[0027] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, the patent owner may make various variations or modifications within the scope of the appended claims. As long as they do not exceed the scope of protection described by the claims of the present invention, they should be within the scope of protection of the present invention.
