Description

Technical Field

[0001] This utility model relates to the field of battery assembly technology, and in particular to a plastic battery product with an improved casing fixing structure. Background Technology

[0002] With the rapid development of portable electronic devices, users have placed higher demands on the portability, battery life, and performance of these devices. To meet these demands, the integration of internal components and space utilization have become key design challenges. Among these, the layout and structural design of the battery, motherboard, and display panel, as core components, directly affect the overall size, weight, and performance of the device.

[0003] In traditional device internal structure designs, the battery, motherboard, and display panel are typically arranged separately and secured and connected by additional structural components. While this design is simple and reliable, it also has significant drawbacks. Specifically, a large structural space needs to be reserved between the battery, motherboard, and display panel to accommodate mounting components, connectors, and heat dissipation materials. This results in the underutilization of internal space, limiting further reduction in overall device size and making it difficult to meet users' demands for thinner and lighter devices.

[0004] To improve space utilization, the industry has tried various optimization solutions. For example, designing batteries in irregular shapes to better fit the internal space of devices. However, the design of irregularly shaped batteries is limited by the requirements of battery manufacturing processes and energy density, making it difficult to fully adapt to the internal spatial form of devices. Therefore, existing technologies cannot fundamentally solve the problem of wasted space between batteries, motherboards, and display panels, making it difficult to achieve greater compactness in the internal structural design of devices.

[0005] In summary, the current layout of the battery, motherboard, and display panel suffers from low space utilization, limiting the overall compactness of the device and failing to meet users' demands for thinner, lighter, and higher-performance devices. Therefore, there is an urgent need for an innovative internal structure design that can effectively improve space utilization, optimize component layout, and achieve efficient use of internal space, thereby driving the development of portable electronic devices towards thinner, lighter, and higher-performance devices.

The upper end of the outer casing 10 is provided with a protruding window portion 11. The display panel 20, the battery cell body 30, and the main circuit board 40 are all installed inside the outer casing 10, with the display panel 20 abutting against the window portion 11. The main circuit board 40 is pressed against one side of the battery cell body 30. The battery cell connector... The battery cell connector 50 is connected to one end of the battery cell body 30; the battery cell connector 50 is electrically connected to the battery cell body 30; the main circuit board 40 and the battery cell connector 50 are electrically connected through the first flexible circuit board 60; the main circuit board 40 and the display panel 20 are electrically connected through the second flexible circuit board 70; the bracket 80 is disposed between the battery cell body 30 and the display panel 20, the lower end of the bracket 80 is adapted to the battery cell body 30, and the upper end of the bracket 80 is adapted to the display panel 20, so that the battery cell body 30 and the display panel 20 are pressed against the inside of the outer casing 10 by the bracket 80.

[0029] By setting a structure with a protruding window portion 11, the display panel 20 is positioned and engaged with the window portion 11. Then, using the structure of the battery cell body 30 and the bracket 80, the battery cell body 30 and the display panel 20 are firmly fixed inside the housing 10 by the bracket 80. The main circuit board 40 is pressed between the side of the battery cell body 30 and the inside of the housing 10. The display panel 20, the battery cell body 30 and the main circuit board 40 are electrically connected through the battery cell connector 50, the first flexible circuit board 60 and the second flexible circuit board 70.
