Description

Technical Field

[0001] This utility model relates to the field of battery casing technology, specifically to an explosion-proof battery casing for forklifts. Background Technology

[0002] With the development of technology, forklifts are being used more and more widely in industrial production. Electric forklifts, with their advantages such as environmental protection and low noise, are gradually becoming the mainstream. The power source of electric forklifts is mainly batteries, and the safety of batteries is of paramount importance, requiring the use of explosion-proof battery casings.

[0003] The prior art patent document CN215896583U provides an explosion-proof battery housing for forklifts. This device makes the battery housing easy to carry by setting up mounting blocks and handles, improving the applicability of the device and saving manpower. By setting fixing bolts, the first and second connecting parts can be fixed, and the battery housing cover is fixed to the battery housing body to prevent it from loosening. By setting vent holes and vent valves, the internal pressure and heat of the battery after being heated can be released, preventing the pressure value from being too high and causing an explosion.

[0004] While the existing technology can release internal pressure, it relies solely on heat dissipation plates embedded on both sides of the battery casing. This single heat dissipation method and limited heat dissipation area make it difficult to meet the rapid heat dissipation requirements of batteries during high-intensity forklift operations. Therefore, we need an explosion-proof battery casing for forklifts. Utility Model Content

[0005] The purpose of this invention is to provide an explosion-proof battery housing for forklifts to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an explosion-proof battery housing for forklifts, comprising a battery housing body, wherein two explosion-proof partitions are fixedly connected to the inner wall of the battery housing body, and the two explosion-proof partitions divide the interior of the battery housing body into three independent battery mounting cavities; a battery housing cover is fixedly connected to the top of the battery housing body by bolts; a vent valve is installed on the outer wall of the battery housing body; a heat dissipation component is provided at the bottom of the battery housing body; and an installation component is provided on the outer wall of the battery housing body.

[0007] The heat dissipation component includes a mounting slot, and a circulating air duct is fixedly connected to the inner wall of the mounting slot. One end of the circulating air duct is provided with an air inlet pipe, and the other end of the circulating air duct is provided with an air outlet pipe. A base plate is fixedly connected to the bottom of the battery casing body.

[0008] The installation assembly includes a fixing groove, and the inner wall of the fixing groove is provided with a heat-conducting plate. A heat-conducting block is fixedly connected to the outer wall of the heat-conducting plate, and a fixing bolt is provided on the outer wall of the heat-conducting plate. Heat dissipation fins are fixedly connected to the outer wall of the heat-conducting plate, and a protective net is fixedly connected to the outer wall of the heat-conducting plate by bolts.

[0009] Preferably, one end of the air inlet pipe extends into the battery casing and connects to the circulation duct, and one end of the air outlet pipe extends into the battery casing and connects to the circulation duct.

[0010] Preferably, the inner wall of the base plate has four mounting holes.

[0011] Preferably, there are three venting valves, and the three venting valves are arranged at equal intervals on the battery casing.

[0012] Preferably, the inner wall shape and size of the fixing groove match the outer wall shape and size of the heat-conducting plate, and the inner wall of the fixing groove is in contact with the outer wall of the heat-conducting plate.

[0013] Preferably, the battery casing body is fixed to the heat-conducting plate by fixing bolts, and one end of the fixing bolt is threaded through the heat-conducting plate and extends into the battery casing body for connection.

[0014] Preferably, there are multiple heat dissipation fins, and the multiple heat dissipation fins are arranged at equal intervals on the heat conduction plate.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model is equipped with an installation groove, a circulating air duct, an air inlet pipe, an air outlet pipe, and a base plate. The heat generated by the battery during operation can be efficiently transferred to the circulating air duct installed inside the battery casing. After connecting the air inlet pipe to the external fan pipe and starting the fan, the outside air quickly enters the circulating air duct and flows. During the flow of the air in the circulating air duct, the outside air comes into full contact with the high-temperature circulating air duct wall and exchanges heat, quickly carrying away the heat from the duct wall. Then it is discharged through the air outlet pipe, which improves the heat dissipation efficiency, can quickly reduce the battery temperature, and effectively ensure that the battery operates stably at a suitable temperature.

[0017] Secondly, this utility model is equipped with a fixing groove, a heat-conducting plate, a heat-conducting block, fixing bolts, heat dissipation fins, and a protective net. The heat generated by the battery during operation can be conducted to the heat-conducting plate through the heat-conducting block. The heat-conducting plate conducts the heat to multiple heat dissipation fins. The arrangement of multiple heat dissipation fins increases the heat dissipation area, accelerates the dissipation of heat to the outside, and improves the heat dissipation efficiency. The protective net can protect the heat dissipation fins, prevent external objects from colliding with or scratching the heat dissipation fins, and avoid the heat dissipation effect being affected by damage to the heat dissipation fins.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5As shown, an explosion-proof battery housing for forklifts includes a battery housing body 1. Two explosion-proof partitions 2 are fixedly connected to the inner wall of the battery housing body 1, dividing the interior of the battery housing body 1 into three independent battery mounting cavities 3. A battery housing cover 4 is fixedly connected to the top of the battery housing body 1 by bolts. A vent valve 5 is installed on the outer wall of the battery housing body 1. A heat dissipation assembly 6 is provided at the bottom of the battery housing body 1, and a mounting assembly 7 is provided on the outer wall of the battery housing body 1. The heat dissipation assembly 6 includes a mounting groove 601, and a mounting component 7 is fixedly connected to the inner wall of the mounting groove 601. The circulating air duct 602 has an air inlet pipe 603 at one end and an air outlet pipe 604 at the other end. A base plate 605 is fixedly connected to the bottom of the battery casing body 1. The mounting assembly 7 includes a fixing groove 701, and a heat-conducting plate 702 is provided on the inner wall of the fixing groove 701. A heat-conducting block 703 is fixedly connected to the outer wall of the heat-conducting plate 702, and fixing bolts 704 are provided on the outer wall of the heat-conducting plate 702. Heat dissipation fins 705 are fixedly connected to the outer wall of the heat-conducting plate 702, and a protective net 706 is fixedly connected to the outer wall of the heat-conducting plate 702 by bolts.

[0026] Through the above technical solution, the heat generated by the battery operation can be efficiently transferred to the circulating air duct 602 installed inside the battery casing 1. After connecting the air inlet pipe 603 to the external fan pipe and starting the fan, the outside air quickly enters the circulating air duct 602 and flows. During the flow of the outside air in the circulating air duct 602, the outside air comes into full contact with the high-temperature circulating air duct wall 602 and exchanges heat, quickly carrying away the heat from the pipe wall. Then it is discharged through the air outlet pipe 604, which improves the heat dissipation efficiency, can quickly reduce the battery temperature, and effectively ensure that the battery operates stably at a suitable temperature. The heat generated by the battery operation can be conducted to the heat conduction plate 702 through the heat conduction block 703. The heat conduction plate 702 conducts the heat to multiple heat dissipation fins 705. The arrangement of multiple heat dissipation fins 705 increases the heat dissipation area, accelerates the dissipation of heat to the outside, and improves the heat dissipation efficiency. The heat dissipation fins 705 can be protected by the protective net 706 to prevent external objects from colliding with or scratching the heat dissipation fins 705, and avoids the heat dissipation effect being affected by damage to the heat dissipation fins 705.

[0027] Specifically, one end of the air intake pipe 603 extends into the battery casing body 1 and is connected to the circulation air pipe 602, and one end of the air outlet pipe 604 extends into the battery casing body 1 and is connected to the circulation air pipe 602.

[0028] Through the above technical solution, the bottom of the battery casing body 1 is provided with an installation groove 601, and the two sides of the battery casing body 1 are provided with fixing grooves 701. One end of the air inlet pipe 603 and the air outlet pipe 604 are provided with flanges to facilitate connection with pipelines. The air inlet pipe 603 is connected to the external fan pipeline, and the air outlet pipe 604 is connected to the external air outlet pipeline.

[0029] Specifically, the inner wall of the base plate 605 has four mounting holes.

[0030] The above technical solution provides four mounting holes, which facilitates fixing the battery casing 1 to the device using bolts.

[0031] Specifically, there are three venting valves 5, and the three venting valves 5 are equally spaced on the battery casing body 1.

[0032] Through the above technical solution, the vent valve 5 corresponds to three independent battery mounting chambers 3. During the battery operation, due to chemical reactions and other reasons, gas may be generated inside, causing the pressure to rise. When the pressure reaches a certain level, the vent valve 5 will automatically open to release the excess gas, so as to ensure that the pressure inside the battery casing is within a safe range. The battery casing body 1 is divided into three independent battery mounting chambers 3 by two explosion-proof partitions 2. The independent battery mounting chambers 3 can realize the partition management of the battery. When a battery in one of the battery mounting chambers 3 experiences an abnormal situation such as short circuit, overheating or even explosion, the explosion-proof partition 2 can form an effective physical barrier. With its high strength, high temperature resistance and explosion-proof characteristics, it can prevent flames, high temperature gases and shock waves from spreading to other battery mounting chambers 3, thereby avoiding the chain reaction of the fault and controlling the impact of the accident to a minimum.

[0033] Specifically, the inner wall shape and size of the fixing groove 701 match the outer wall shape and size of the heat-conducting plate 702, and the inner wall of the fixing groove 701 fits against the outer wall of the heat-conducting plate 702.

[0034] The above technical solution facilitates the placement of the heat-conducting plate 702 into the fixing groove 701 for assembly, ensuring the installation of the heat-conducting plate 702.

[0035] Specifically, the battery casing body 1 is fixed to the heat-conducting plate 702 by fixing bolts 704, and one end of the fixing bolts 704 is threaded through the heat-conducting plate 702 and extends into the battery casing body 1 for connection.

[0036] With the above technical solution, there are multiple fixing bolts 704, which can effectively fix the heat conduction plate 702 to the battery casing body 1, making it easy to install and disassemble.

[0037] Specifically, there are multiple heat dissipation fins 705, and these multiple heat dissipation fins 705 are arranged at equal intervals on the heat conduction plate 702.

[0038] Through the above technical solution, the heat dissipation fins 705 arranged at multiple equal intervals increase the heat dissipation area. When the heat is conducted to the heat conduction plate 702, the heat dissipation fins 705 can quickly dissipate the heat into the surrounding air.

[0039] In use, the intake pipe 603 is connected to the air intake duct of the fan on the forklift, and the exhaust pipe 604 is connected to the air exhaust duct on the forklift. When the forklift starts, the battery begins to work, generating heat during the chemical reaction. Some of this heat is conducted to the circulating air duct 602 installed in the mounting slot 601 at the bottom of the battery casing 1. At this time, with the fan on the forklift working, outside air quickly enters the circulating air duct 602 from the intake pipe 603 under the action of the fan. As the outside air flows in the circulating air duct 602, it comes into full contact with the warmer duct wall, exchanging heat rapidly. The heat is quickly absorbed from the tube wall and then discharged to the outside through the vent pipe 604, reducing the temperature around the battery. Another part of the heat is conducted to the heat-conducting plate 702 through the heat-conducting block 703. The heat-conducting plate 702 conducts the heat to multiple heat dissipation fins 705 and dissipates it into the surrounding air. The protective net 706 protects the heat dissipation fins 705 from collisions and scratches by external objects, ensuring stable heat dissipation. This completes the entire process. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
