Technical Field
[0001] This utility model relates to the field of control box technology, and in particular to a multi-channel heat dissipation control box structure for intelligent management of electric vehicle batteries. Background Technology
[0002] With the continuous development of electric vehicle technology, the performance and safety of batteries, as the core component of electric vehicles, are receiving increasing attention. To improve battery performance and safety, a multi-channel heat dissipation control box for intelligent battery management in electric vehicles has emerged.
[0003] The battery management system (BMS) is the core component of the control box, responsible for monitoring the battery status, including parameters such as voltage, current, and temperature, and adjusting the operation of the cooling system based on these parameters. The BMS can also communicate with other systems, such as the vehicle's computer and charging system, via a communication interface to share battery status information and control commands. For example, Chinese patent publication number "CN217239603U" provides an electric vehicle battery box, including a box body. Positioning holes are provided on the upper sides of both sides of the box body. Sliding grooves are provided on both sides of the inner wall of the box body. A box cover is fixedly installed at the upper end of the box cover. A fixing groove is provided in the middle of the upper end of the box cover. A mounting cylinder is fixedly installed inside the fixing groove. A cooling fan is fixedly installed in the middle of the mounting cylinder. Connecting plates are fixedly installed on both sides of the lower end of the box cover. A mounting groove is provided on the middle outer surface of the connecting plate. A positioning block is movably installed inside the mounting groove. A connecting shaft is fixedly connected to the lower end of the positioning block. A torsion spring is fixedly installed inside the mounting groove on one side of the positioning block. The box body includes an outer shell and a protective layer. This utility model can effectively protect the electric vehicle battery through the battery box, effectively improve the use effect of the electric vehicle battery box, and is practical.
[0004] Currently, when storing the batteries of some large electric vehicles, multiple batteries need to be housed in an integrated box to protect them from dust and accidental contact. However, conventional storage box structures rely solely on heat conduction from the casing or natural ventilation through heat dissipation holes to cool the batteries during continuous operation. If the ambient temperature is high, the heat dissipation efficiency of this method will be greatly reduced. Furthermore, most storage control box structures allow the batteries to be placed close together when installed, which can easily cause heat transfer, leading to overheating and reduced battery life. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a multi-channel heat dissipation control box structure for intelligent management of electric vehicle batteries.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a multi-channel heat dissipation control box structure for intelligent management of electric vehicle batteries, including a box body. A partition plate is fixedly installed on the inner wall of the box body. The partition plate has a cross structure and the partition plate and the box body form four battery slots of equal size. The battery body is placed inside any one of the battery slots.
[0008] A connecting plate is installed through one side of the inner wall of the battery compartment. A cylinder is fixed through the inside of the connecting plate. A motor is fixedly installed on the inner wall of the cylinder by a bracket. The motor has a rotating shaft for driving inside. Several blades are fixedly distributed on the surface of the rotating shaft. Dustproof nets are fixedly embedded on both sides of the inner wall of the cylinder.
[0009] A heat dissipation hole is provided at one end of the inner wall of the battery compartment, and a second dustproof net is embedded and fixed inside the heat dissipation hole. Both the second dustproof net and the first dustproof net are made of aluminum alloy wire mesh material.
[0010] In detail, the upper part of the box body is covered with a box cover, and a battery management component is fixedly installed on the upper part of the box cover. A power interface is provided at the lower part of the battery management component. The power interface extends through the box cover into the interior of the box body. The power interface of the battery management component is connected to the terminal of the battery body through a wire.
[0011] In detail, threaded posts are fixedly installed on the lower ends of both sides of the box cover, and collars are fixedly installed on both sides of the box body through brackets. The threaded posts and collars are slidably sleeved together.
[0012] In detail, the other end of the threaded column is threaded with a threaded cap, the end face of the threaded cap is tightly fitted against the end of the collar, and knobs are fixedly installed on the surface of the threaded cap.
[0013] In detail, the box body and the connecting plate have a through hole at the through position. The through hole is a rectangular hole, and the upper and lower ends of its inner wall are provided with pin grooves.

[0017] 1. This solution divides the internal space into four independent battery compartments using a cross-shaped partition, achieving physical isolation of the battery body and preventing heat accumulation. Each battery compartment is equipped with an independent air-cooling system (motor-driven blades) and a multi-channel heat dissipation structure (dustproof mesh one, heat dissipation holes, and dustproof mesh two), forming a directional airflow circulation, significantly improving heat dissipation efficiency. At the same time, the battery management components integrated into the cover (including power control and monitoring functions) can regulate the power status in real time. Combined with the multi-channel heat dissipation design, this effectively solves the problem of performance degradation of electric vehicle batteries caused by high temperatures, extends battery life, and ensures operational safety.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Reference Figures 1-6 A multi-channel heat dissipation control box structure for intelligent management of electric vehicle batteries includes a box body 1. A partition plate 11 is fixedly installed on the inner wall of the box body 1. The partition plate 11 has a cross structure and forms four battery slots 12 of equal size with the box body 1. A battery body 13 is placed inside any one of the battery slots 12. The partition plate 11 can reasonably divide the space inside the box body 1 into four areas for placing the battery body 13, so that the battery bodies 13 can be separated from each other.
[0028] A connecting plate 14 is installed through one side of the inner wall of the battery compartment 12. A cylinder 15 is fixed through the inside of the connecting plate 14. A motor 16 is fixedly installed on the inner wall of the cylinder 15 by a bracket. The motor 16 has a rotating shaft for driving inside. Several blades 17 are fixedly distributed on the surface of the rotating shaft. Dustproof nets 18 are fixedly embedded on both sides of the inner wall of the cylinder 15. The rotating shaft of the motor 16 drives the blades 17 to rotate, which can generate airflow, thereby transporting air into the inside of the battery compartment 12 and accelerating the air circulation inside. Thus, when the battery body 13 is working continuously, it can circulate and remove more heat. The dustproof nets 18 can provide dust protection at the air inlet.
[0029] A heat dissipation hole 19 is provided at one end of the inner wall of the battery compartment 12. A second dustproof mesh 110 is embedded and fixed inside the heat dissipation hole 19. Both the second dustproof mesh 110 and the first dustproof mesh 18 are made of aluminum alloy wire mesh. The heat dissipation hole 19 can ensure that air can pass through normally when air circulates inside the battery compartment 12. Each battery compartment 12 is equipped with a first dustproof mesh 18 and a second dustproof mesh 110, which can form a multi-channel heat dissipation structure on a box 1, thereby allowing the battery body 13 to be cooled down one-to-one.
[0030] It should be further explained that the upper end of the box body 1 is covered by a cover 2, and a battery management component 21 is fixedly installed on the upper end of the cover 2. A power interface is provided at the lower end of the battery management component 21. The power interface extends through the cover 2 into the interior of the box body 1. The power interface of the battery management component 21 is connected to the terminal of the battery body 13 through a wire. The battery management component 21 includes a power controller, a power monitor, and other interfaces. The power controller is used to convert the input power into a power suitable for the load, such as converting AC power to DC power or high voltage power to low voltage power. The power monitor is used to control the power switch and can automatically or manually turn the power on or off according to preset conditions or external instructions.
[0031] It should be further noted that threaded posts 3 are fixedly installed on both lower ends of the lid 2, and collars 31 are fixedly installed on both sides of the body 1 through brackets. The threaded posts 3 and collars 31 are slidably sleeved together. Through the cooperation of the threaded posts 3 and collars 31, the lid 2 and the body 1 can be quickly positioned and connected.
[0032] It should be further explained that a threaded cap 32 is threadedly installed at the other end of the threaded post 3. The end face of the threaded cap 32 is tightly fitted against the end of the collar 31. A knob is fixedly installed on the surface of the threaded cap 32. When it is necessary to remove the box cover 2, the threaded cap 32 is rotated by the knob to separate it from the threaded post 3, thereby separating the box body 1 from the box cover 2.
[0033] It should be further noted that a through hole is provided at the through position of the box body 1 and the connecting plate 14. The through hole is a rectangular hole, and pin grooves 4 are provided at both the upper and lower ends of its inner wall. The through hole facilitates the installation of the connecting plate 14, so that the airflow generated by the blade 17 can communicate with the battery slot 12.
[0034] It should be further explained that a locking pin 41 is slidably sleeved inside the pin groove 4. The end face of the locking pin 41 is a curved structure. A spring 42 is installed inside the pin groove 4. The two ends of the spring 42 are fixedly installed to the end face of the locking pin 41 and the inner wall of the pin groove 4, respectively. By compressing and resetting the spring 42, the locking pin 41 can be stably extended and retracted, thereby enabling the locking pin 41 to better engage or disengage with the arc-shaped groove 43.
[0035] It should be further explained that the end face of the connecting plate 14 near the pin groove 4 is provided with an arc-shaped groove 43. The inside of the arc-shaped groove 43 is provided with an inner arc surface. The end curved surface of the locking pin 41 is in close contact with the inner arc surface of the arc-shaped groove 43. During installation, the connecting plate 14 is inserted into the through hole, so that the locking pin 41 is squeezed and the spring 42 is compressed into the inside of the pin groove 4. Then, the connecting plate 14 can move normally through the through hole. When the position of the locking pin 41 corresponds to the position of the arc-shaped groove 43, the return effect of the spring 42 causes the end curved surface of the locking pin 41 to be squeezed into the inner arc surface of the arc-shaped groove 43, thereby fixing the position of the connecting plate 14.
[0036] Working method: This solution divides the interior of the box 1 into four independent battery slots 12 by the partition plate 11. Each battery slot 12 contains a battery body 13, achieving physical isolation. Each battery slot 12 is equipped with an independent heat dissipation system, including a cylinder 15, a motor 16, and blades 17 in the connecting plate 14. When the motor 16 is started, the shaft drives the blades 17 to rotate, generating directional airflow. The airflow enters from the dustproof net 18 on one side of the cylinder 15, passes through the inside of the battery slot 12, and carries away the heat generated by the battery body 13 during operation. Finally, it is discharged through the heat dissipation hole 19 and the dustproof net 110 on the other side. The dustproof net 18 and the dustproof net 110 are made of aluminum alloy wire mesh material, which ensures air circulation and prevents dust from entering.
[0037] The battery management component 21 installed on the cover 2 is connected to the terminal block of the battery body 13 through the power interface to realize intelligent management of the battery. The battery management component 21 includes a power controller and a power monitor: the power controller is responsible for power conversion (such as AC to DC or high voltage to low voltage) to ensure that the load receives a stable power supply; the power monitor monitors the battery status (such as voltage, temperature, etc.) in real time and controls the power supply on and off according to preset conditions or external commands. For example, when the temperature in a battery compartment 12 is too high, the monitor can trigger the motor 16 to accelerate and enhance heat dissipation; if the battery is abnormal, the power supply can be automatically cut off. In addition, the cover 2 and the box body 1 can be quickly connected through the threaded post 3 and the collar 31. The knob design of the threaded cap 32 is easy to disassemble and install, and convenient for maintenance or battery replacement.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
