Description
Technical Field
[0001] This utility model relates to the field of battery technology, and in particular to a battery structure for communication equipment. Background Technology
[0002] With the widespread adoption and development of mobile phones and other communication devices, the high-capacity and high-power performance of lithium-ion batteries has attracted increasing attention. Historically, due to issues with current collection, the lithium battery industry has generally believed that low-capacity conventional batteries are produced using a small cylindrical process, while high-capacity or high-power batteries are produced using a square stacking process.
[0003] Lithium-ion batteries have advantages such as high energy density, small size, long storage life, and no pollution, making them a clean energy source that the country is currently vigorously developing. Square lithium-ion batteries are widely used due to their large capacity and ease of use. Existing battery structures used in mobile phones and other communication devices typically include a fixed frame and a battery body mounted on the fixed frame. The battery body is a square block structure, with the left and right sidewalls of the fixed frame covering the left and right sides of the battery body, respectively. It connects to the motherboard of the mobile phone or other communication device via an FPC board. While the fixed frame can position and fix the battery body to the communication device, the FPC board only considers the conductive connection with the motherboard and lacks a positioning and fixing structure design, resulting in poor stability of the positioning connection.
[0004] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content
[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a battery structure for communication equipment that facilitates assembly and positioning, making the positioning connection more stable.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A battery structure for a communication device includes a fixed frame and a battery body mounted on the fixed frame. The battery body has a square block structure. The left and right sidewalls of the fixed frame cover the left and right sides of the battery body, respectively. A fixed steel plate is provided on the rear side of the lower end of the fixed frame. A connecting plate extends integrally downward from the lower end of the fixed steel plate, protruding beyond the lower end of the fixed frame. The connecting plate has a connecting hole. An FPC board is provided on the surface of the battery body. The FPC board has a first plate portion, a second plate portion, and a bent plate portion. The two ends of the bent plate portion are respectively connected to the first plate portion and the second plate portion. The first plate portion and the second plate portion are located on the front and rear sides of the battery body, respectively. The bent plate portion is located outside the right side wall of the fixed frame. A first connecting end is provided at the end of the first plate portion away from the bent plate portion, and a connector is fixed on the first connecting end. A second connecting end is provided at the end of the second plate portion away from the bent plate portion. The second connecting end is positioned on the rear side of the fixed steel plate, and a connecting terminal is provided on the side of the second connecting end facing away from the fixed steel plate.
[0008] As a preferred embodiment, there are two connecting plates arranged symmetrically on the left and right, and each connecting plate has a connecting screw in its connecting hole.
[0009] As a preferred embodiment, the rear sidewall of the fixing steel sheet is provided with a positioning part, and a limiting protrusion extends integrally rearward from the lower part of the positioning part on the rear sidewall of the fixing steel sheet. The second connecting end is positioned inside the positioning part, and the lower end of the second connecting end is restricted by the upper end of the limiting protrusion.
[0010] As a preferred embodiment, the positioning part has a first positioning hole on the fixing steel plate and a second positioning hole on the second connecting end, with the first positioning hole and the second positioning hole being provided correspondingly.
[0011] As a preferred embodiment, the connecting plate is integrally connected to the lower end of the fixed steel sheet via a bending portion, which bends downward from back to front and extends outside the lower end of the fixed frame.
[0012] As a preferred embodiment, the first plate extends in the left-right direction, and a first bending extension is connected to the end of the first plate away from the bending plate, and the first connecting end is connected to the end of the first bending extension away from the first plate.
[0013] As a preferred embodiment, the second plate extends in the left-right direction, and a second bending extension is connected to the end of the second plate away from the bending plate, and the second connecting end is connected to the end of the second bending extension away from the second plate.
[0014] As a preferred embodiment, the lower end of the bent plate portion extends downward to form an extended covering portion, which covers the outside of the right side wall of the fixed frame.
[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves setting a fixing steel plate on the rear side of the lower end of the fixing frame, so that the lower end of the fixing steel plate extends downward integrally with a connecting plate part, and a connecting hole is set in the connecting plate part. The second connecting end of the FPC board is positioned on the rear side of the fixing steel plate. In this way, the second connecting end of the FPC board can be positioned and connected to the external structure through the fixing steel plate and the connecting plate part, which facilitates its assembly and positioning, and makes the positioning connection more stable.
[0016] To more clearly illustrate the structural features, technical means, and specific objectives and functions of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description
