Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and in particular relates to a mobile phone lithium battery with good bending resistance. Background Technology

[0002] The primary function of a mobile phone lithium battery is to power the phone. It uses lithium metal or lithium alloy as the negative electrode material and is composed of a non-aqueous electrolyte solution. Thanks to its high energy density, this battery provides long-lasting and stable battery life, ensuring users enjoy a smooth and uninterrupted experience during calls, web browsing, and gameplay. Furthermore, lithium batteries offer numerous advantages such as long cycle life, no memory effect, and environmental friendliness. These characteristics not only extend the phone's lifespan but also enhance the user experience, bringing a more convenient, efficient, and worry-free smart life.

[0003] However, existing mobile phone lithium batteries generally adopt a rigid structure design and do not have the ability to bend. This characteristic makes lithium batteries easy to bend when subjected to external impact. Physical deformation of mobile phone lithium batteries often leads to leakage of electrolyte inside the battery. Once the electrolyte comes into contact with other materials in the battery, it will greatly increase the risk of short circuit, which may lead to serious consequences such as high temperature or even explosion.

[0004] To address these issues, we provide a mobile phone lithium battery with good bending resistance. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile phone lithium battery with good bending resistance. The outer sheath provides protection for the battery, and multiple connecting strips allow the multiple battery parts to be bent at a certain angle, which solves the problem that mobile phone batteries are easily bent and damaged after being impacted, causing leakage and explosion.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a mobile phone lithium battery with good bending resistance, including multiple battery units and multiple mounting frames; the multiple battery units are installed inside the corresponding mounting frames, each mounting frame has a heat dissipation component installed inside, the multiple mounting frames are fixedly connected by connecting strips, and the multiple mounting frames are covered with an outer protective sleeve.

[0008] The present invention is further configured such that the mounting frame includes a lower frame and an upper frame, and the battery is separately located between the lower frame and the upper frame. A fixing post is fixedly connected to each of the four corners of the lower frame, and a fixing seat is fixedly connected to each of the four corners of the upper frame. A fixing screw is rotatably connected inside each of the four fixing seats, and the fixing screw is threaded into the inside of the corresponding fixing post.

[0009] The present invention is further configured such that the heat dissipation component includes two heat-conducting plates, which are respectively attached to the top and bottom of the battery assembly, and multiple heat dissipation fins are fixedly connected to the opposite side of each heat-conducting plate.

[0010] The present invention is further configured such that two pressure strips are fixedly connected to the inner sides of both the lower frame and the upper frame, and the heat-conducting plate is in contact with the pressure strips.

[0011] The present invention is further configured such that the pressure strip has multiple slots on the side facing the heat conduction plate, and the heat dissipation fins are snapped into the corresponding slots.

[0012] The present invention is further provided that thermal grease is applied between the heat-conducting plate and the battery.

[0013] The present invention is further configured such that the connecting strip includes two connecting frames, and the two connecting frames are respectively fixedly connected to the outside of two adjacent lower frames, and multiple connecting brackets are fixedly connected between the two connecting frames.

[0014] The present invention is further configured such that the connecting frame is an X-shaped rubber strip.

[0015] The present invention is further configured such that the outer sheath is a rubber sleeve and the outer sheath has a mesh structure.

[0016] This utility model has the following beneficial effects:

[0017] 1. The outer sheath with a mesh structure can act as a buffer, and the X-shaped connecting frame can make multiple batteries bend at a certain angle, thereby preventing leakage and explosion caused by bending.

[0018] 2.

[0029] Specifically, the mounting frame 2 includes a lower frame 201 and an upper frame 203, and the battery assembly 1 is located between the lower frame 201 and the upper frame 203.
