Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and in particular to a battery mounting rack and a power supply assembly. Background Art

[0002] At present, conventional batteries are all flat plate structures or round column structures, which are suitable for powering common electrical appliances. However, with the popularization of new consumer electronic products, the use scenarios of special-shaped batteries have high requirements. For example, when used in wearable scenarios such as VR glasses, bracelets, and special-shaped body massage equipment, the installation space of special-shaped equipment such as VR glasses, bracelets, and body massage is narrow and arc-shaped. These standard flat plate structures or round column structures cannot be installed in a matching manner. Even if the outer shell structure of special-shaped electronic products is modified to form a space for accommodating batteries, only a small number of batteries can be installed, resulting in low total power and short standby time.

[0003] Moreover, even if multiple battery cells are fixed in a plastic frame and integrated with PCM (pulse code modulation) and then wrapped with polyester film (Mylar) to form a battery pack, when using the battery pack, the plastic frame is fixed by screws. Installation and disassembly require tightening and loosening the screws, which is inconvenient. In addition, thin plastic frames are not easy to form a certain angle, and are prone to brittle cracks due to insufficient strength. Thicker plastic materials are easy to shrink and difficult to form, and are difficult to apply to wearable scenarios such as VR glasses and bracelets, as well as special-shaped human massage equipment scenarios. Therefore, the current battery packs also have the problem of being difficult to quickly install and disassemble in curved installation spaces. Summary of the invention

The thickness of the battery mounting frame 10 can be 0.3-1.0mm, and the stamping direction is in the direction of the buckle 102 to avoid the formation of burrs on the upper surface and piercing the battery assembly 20 installed on the upper surface of the battery mounting frame 10. The formed battery mounting frame 10 is electrolytically polished, and the surface is cleaned for rust prevention and burrs are removed. It must be noted that the selection of materials with high corrosion resistance and hardness is within the protection scope of this solution. In order to facilitate the installation of the battery assembly 20 on the battery mounting frame 10 on the shell, a plurality of first positioning holes 101 may be provided on the battery mounting frame 10, and the battery assembly 20 is provided with a second positioning hole 201 at a position corresponding to the first positioning hole 101, and the battery mounting frame 10 is fixed to the shell by fasteners, wherein the first positioning holes 101 and the second positioning holes 201 may be of any number, size, and position without limitation, and the number, size, and position of the undercuts 102 are not limited, and any deformation and combination made in this way are within the protection scope of this scheme.

It is preferred that the lengths of the first frame plate 11 and the second frame plate 13 are equal, and the first frame plate 11 and the second frame plate 13 are mirror-imaged relative to a central symmetry axis of the middle connecting plate 12, so that the structure can be symmetrical as a whole. The battery mounting rack 10 with a curved surface structure formed is W-shaped, V-shaped or U-shaped as a whole. It is understandable that the first frame plate 11 and the second frame plate 13 may not be mirror-imaged, and the battery mounting rack 10 with a curved surface structure formed at this time may also be Z-shaped as a whole.

[0034] A first bending member 1 is provided on the first side of the middle connecting plate 12 and is connected to the first frame plate 11 with an adjustable angle, and a second bending member 2 is provided on the second side of the middle connecting plate 12 and is connected to the second frame plate 13 with an adjustable angle.

During installation, the battery assembly 20 is positioned through the positioning hole 101, and the left and right batteries are gently pressed together so that the undercut 102 on the first frame plate 11 and the second frame plate 13 are engaged with the hook on the shell. The easy-pull adhesive 24 on the lower surface of the battery mounting frame 10 can be removed by pulling the handle 241, which is convenient for customers to assemble and disassemble the battery.

[0037] When the first frame plate 11 and the second frame plate 13 are mirror-imaged on both sides of the middle connecting plate 12, the middle connecting plate 12 is horizontally arranged, the plane where the first frame plate 11 is located and the plane where the middle connecting plate 12 is located have a first angle, the plane where the second frame plate 13 is located and the plane where the middle connecting plate 12 is located have a second angle, and the first angle and the second angle are equal.
