Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology; more specifically, it relates to a lithium iron phosphate battery pack that is easy to maintain. Background Technology

[0002] The field of lithium-ion battery technology refers to a comprehensive field involving a series of technologies and scientific research related to the design, development, manufacturing, application and management of lithium-ion batteries. Its working principle is based on the movement of lithium ions between positive and negative electrode materials. A type of lithium iron phosphate battery pack that is easy to maintain is often used in the field of lithium-ion battery technology. By combining multiple battery cells together, higher voltage and capacity can be achieved to meet the needs of different application scenarios.

[0003] Currently, existing battery packs typically have batteries fixed in place during use. This can be inconvenient when the equipment needs to be inspected or repaired after long-term use, reducing the equipment's convenience to some extent. Furthermore, existing battery packs often make it difficult to cool the equipment, which may lead to battery swelling, leakage, or even explosion, reducing the equipment's safety. Therefore, there is an urgent need for an easy-to-maintain lithium iron phosphate battery pack to solve these problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lithium iron phosphate battery pack that is easy to maintain, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a lithium iron phosphate battery pack that is easy to maintain, comprising a battery body and a housing box.

[0006] The battery body is provided with multiple sets, and the placement box has multiple sets of square slots that cooperate with the battery body. The battery body is installed in the square slots. Rubber strips are fixed on both sides of the square slots. Vents are provided on both sides of the square slots. A cooling box is attached to the lower surface of the placement box.

[0007] Preferably, the upper end of the placement box is provided with a seal, one end of which is hinged to one side of the placement box, and the other end of which is fixedly connected to the other side of the placement box by bolts. This design can be used to fix the position of multiple battery bodies and improve the stability of the battery bodies during use.

[0008] Preferably, the vents are vertically and evenly distributed inside the placement box, and the rubber strips are horizontally and evenly distributed from top to bottom on the inner wall of the square groove. With the help of the vents, the heat generated by the battery body during use can be transferred. The battery body may bulge during long-term use. At this time, the elasticity of the rubber strips can buffer the pressure when the internal pressure of the battery body increases, help to disperse the pressure, and prevent the battery body from being squeezed and damaged.

[0009] Preferably, the cooling box is a hollow aluminum structure. This design allows the cooling box to better hold cold water while reducing the weight of the equipment.

[0010] Preferably, a water inlet is fixedly connected to one side of the upper end of the cooling box, and a sealing cap is threaded onto the surface of the water inlet. The use of the water inlet allows cold water to enter the interior of the cooling box more effectively.

[0011] Preferably, a support column is fixed inside the lower end of the cooling box, and multiple sets of support columns are provided to support the interior of the cooling box and prevent the battery body from being deformed or damaged due to excessive weight.

[0012] The technical effects and advantages of this utility model are as follows: This utility model removes the seal by rotating the bolt, then hinges the rotating seal at one end of the placement box, and then, through the cooperation of the placement box and the rubber strip, the battery body can be easily taken out, avoiding the situation where the device is inconvenient to maintain or install after long-term use, thus improving the convenience of the device to a certain extent.

[0013] By using the exhaust vents in conjunction with the cooling system, when the battery body emits heat, the hot air can be exhausted to the bottom of the storage box. Then, cold water is poured back into the cooling box from the inlet. Through the coverage and conduction of the cold water, the overall temperature of the cooling box is reduced. At the same time, multiple battery bodies are cooled and vented, preventing the battery bodies from expanding, leaking, or even exploding, thus improving the safety of the equipment to a certain extent.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The lithium-ion battery involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown, this embodiment proposes a lithium iron phosphate battery pack that is easy to maintain, including a battery body 1, which has multiple sets of square slots that cooperate with the battery body 1 inside the placement box 2. The battery body 1 is installed inside the square slots. Rubber strips 4 are fixed on both sides of the square slots. Vents 5 are opened on both sides of the square slots. A sealing strip 3 is provided at the upper end of the placement box 2. One end of the sealing strip 3 is hinged to one side of the placement box 2, and the other end of the sealing strip 3 is fixed to the other side of the placement box 2 by bolts. The vents 5 are vertically and evenly opened inside the placement box 2. The rubber strips 4 are horizontally and evenly distributed from top to bottom on the inner wall of the square slots.

[0022] In this embodiment, multiple battery bodies 1 and placement box 2 can be used or installed as a whole. By rotating the sealing strip 3 clockwise so that its lower surface is in contact with the upper surface of the placement box 2, the position of multiple battery bodies 1 can be fixed. By rotating the sealing strip 3 counterclockwise, the battery body 1 can be moved out of the placement box 2 for replacement or testing. With the cooperation of the rubber strip 4, the battery body 1 can be prevented from being damaged by expansion and compression during use. When the battery body 1 generates heat during use, the heat can be dissipated through the vent 5.

[0023] Example 2

[0024] like Figure 3 and Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: a cooling box 6 is attached to the lower surface of the placement box 2, the cooling box 6 is a hollow aluminum structure, a water inlet 7 is fixedly connected to one side of the upper end of the cooling box 6, and a sealing cap is threadedly connected to the surface of the water inlet 7, and a support column 8 is fixed inside the lower end of the cooling box 6, and multiple sets of support columns 8 are provided.

[0025] In this embodiment, by using the inlet 7 and the sealing cap together, cold water can be backflowed from the inside of the inlet 7 into the cooling box 6. Then, the sealing cap is rotated to isolate the cold water, which allows for convenient replacement of the cold water. The material of the cooling box 6 reduces the weight of the equipment, making it more convenient to operate or use. By using multiple sets of support columns 8 together, multiple battery bodies 1 can be supported, which can prevent the cooling box 6 from deforming or being damaged due to excessive weight of the battery bodies 1, and at the same time improve the service life of the equipment.

[0026] Working principle: When using the equipment, first install the cooling box 6 in a suitable position, then pour cold water into the interior of the cooling box 6 through the water inlet 7, then rotate the sealing cover, then place the placement box 2 on the top of the cooling box 6, and then place multiple battery bodies 1 inside the square slot. Hinged rotating seal 3 and bolts are used to make it threadedly connected to the placement box 2.

[0027] When the device is in use, the heat generated by the multiple battery bodies 1 is cooled and dissipated by the combined use of the exhaust vent 5 and the cold water inside the cooling box 6. At the same time, the rubber strip 4 is used to maintain the stability of the battery body 1 during use and to prevent the battery body 1 from being squeezed and damaged due to expansion during use. The above is the complete working principle of this utility model.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
