Abstract
Description
Technical Field
[0001] This utility model relates to the field of BMS control system technology, specifically to a BMS control system capable of automatic cooling. Background Technology
[0002] BMS is an abbreviation for Battery Management System. The Battery Management System (BMS) plays a crucial role in new energy vehicles. It can monitor the battery status in real time, including parameters such as voltage, current, and temperature, to ensure the safe operation of the battery, thus becoming one of the most important components in a car.
[0003] When existing BMS control systems are in use, a large number of electronic components are installed inside the entire housing. When these electronic components are working, they generate a lot of heat. In order not to affect the internal layout of the housing, only heat dissipation holes are usually provided. However, relying solely on heat dissipation holes cannot effectively dissipate heat from the internal electronic components and does not have the function of automatically cooling the inside of the housing. Utility Model Content
[0004] The purpose of this invention is to provide a BMS control system with automatic cooling, so as to solve the problem mentioned in the background art that the currently used BMS control system does not have automatic cooling.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a BMS control system with automatic cooling capability, comprising: a lower housing and an interface, an upper housing mounted on the top of the lower housing, mounting blocks mounted on both sides of the lower housing, and the interface being located on one side of the lower housing and the upper housing;
[0006] The lower housing contains a mounting shell, which contains a drive motor. The output of the drive motor is connected to a drive shaft via a coupling. A cooling fan is mounted on the outside of the drive shaft. Air inlets are provided on both sides of the mounting shell. The temperature sensor is installed inside the lower housing.
[0007] Preferably, both ends of the mounting housing are connected to air ducts, and the top of the air ducts has an air outlet.
[0008] Preferably, a fixing block is installed on the inner wall of the lower housing, and a movable rod is connected through the middle of the fixing block.
[0009] Preferably, a movable spring is connected between the outer side of the movable rod and the groove of the fixed block, and a pull block penetrating the lower housing is connected to one side of the movable rod.
[0010] Preferably, a connecting block is installed on the side of the movable rod away from the pull block, and a locking block is installed on the side of the connecting block away from the movable rod.
[0011] Preferably, a protrusion is inserted into the middle of the card block through a groove, and the protrusion is installed on the inner wall of the upper housing.
[0012] Preferably, the movable rod forms a telescopic structure with the fixed block via a movable spring.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the automatic cooling BMS control system can monitor the temperature inside the lower housing in real time through a temperature sensor. When the temperature is too high, it will transmit the temperature signal to the control system, which will then control the drive motor to work. The drive motor will drive the cooling fan to rotate through the drive shaft, so that the cooling fan blows air into the lower housing through the air duct and air outlet, thereby increasing the air flow speed inside the lower housing and making the heat dissipation effect of the electronic components inside the lower housing better. At the same time, it has the function of automatic cooling. This is the characteristic of the automatic cooling BMS control system.
[0014] 1. This automatic cooling BMS control system can monitor the internal temperature of the lower housing through a temperature sensor during use, and control the drive motor to work through the control system. The drive motor will drive the cooling fan to rotate through the drive shaft, so that the cooling fan can deliver air into the lower housing through the air duct and air outlet, thereby quickly cooling down the electronic components inside the lower housing and ensuring that the electronic components inside the lower housing can work normally.
[0015] 2. When the electronic components inside the lower housing need to be inspected and maintained, the automatic cooling BMS control system can pull the two sets of pull blocks closer together, so that the pull blocks drive the locking block to move through the movable rod and connecting block. At this time, the locking block will separate from the protrusion on the inner wall of the upper housing. Without the limiting effect of the locking block and the protrusion, the upper housing can be quickly removed from the top of the lower housing, thus facilitating the inspection and maintenance of the electronic components inside the lower housing.

[0023] 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.
[0024] Please see Figure 1 This utility model provides a technical solution: a BMS control system with automatic cooling, including: a lower housing 1 and an interface 4, an upper housing 2 is installed on the top of the lower housing 1, mounting blocks 3 are installed on both sides of the lower housing 1, and the interface 4 is opened on one side of the lower housing 1 and the upper housing 2.
[0025] The lower housing 1 houses a mounting shell 5, and the mounting shell 5 houses a drive motor 6. The output end of the drive motor 6 is connected to a drive shaft 7 via a coupling. A cooling fan 8 is mounted on the outside of the drive shaft 7. Air inlets 9 are provided through the two sides of the mounting shell 5. A temperature sensor 19 is installed inside the lower housing 1. Both ends of the mounting shell 5 are connected to air ducts 10. An air outlet 11 is provided at the top of the air ducts 10. Two sets of cooling fans 8 are symmetrically mounted about the center line of the mounting shell 5.
[0026] In practical implementation, this BMS control system with automatic cooling will detect a temperature change when the temperature inside the housing 1 rises. The temperature sensor 19 will then transmit the measured temperature signal to the control system via wires. Upon receiving the temperature signal, the control system will start the drive motor 6, causing it to rotate the drive shaft 7 via a coupling. A cooling fan 8 is mounted on the outside of the drive shaft 7; therefore, the rotation of the drive shaft 7 will drive the cooling fan 8 to rotate. When the cooling fan 8 rotates, it will draw in air through the air inlets 9 on both sides of the mounting housing 5. A partition is installed on one side of the mounting housing 5 to allow air to escape. The space inside the lower housing 1 is divided into two parts to prevent heat from being drawn into the mounting housing 5 when air is drawn in. When air is drawn into the mounting housing 5 by the cooling fan 8, it flows out through the air ducts 10 at both ends of the mounting housing 5. An air outlet 11 is provided at the top of the air duct 10. When air flows to the air outlet 11 of the air duct 10, it flows out through the air outlet 11, thereby increasing the air flow speed inside the lower housing 1 and allowing heat to flow out of the lower housing 1 quickly, thus achieving the function of automatically cooling the inside of the lower housing 1.
[0027] See Figure 5 and Figure 6 It can be seen that when the temperature sensor 19 senses that the temperature is too high during use, the control system can control the drive motor 6 to work, and together with the drive shaft 7 and the cooling fan 8, air can be blown into the air duct 10 and flow out from the air outlet 11 at the top of the air duct 10, thereby increasing the air flow speed inside the lower housing 1 and making the heat dissipation effect better.
[0028] A fixing block 12 is installed on the inner wall of the lower housing 1. A movable rod 13 is connected through the middle of the fixing block 12. A movable spring 14 is connected between the outer side of the movable rod 13 and the groove of the fixing block 12. A pull block 15 that penetrates the lower housing 1 is connected to one side of the movable rod 13. A connecting block 16 is installed on the side of the movable rod 13 away from the pull block 15. A locking block 17 is installed on the side of the connecting block 16 away from the movable rod 13. A protrusion 18 is inserted into the middle of the locking block 17 through a groove. The protrusion 18 is installed on the inner wall of the upper housing 2. The movable rod 13 forms a telescopic structure with the fixing block 12 through the movable spring 14. The pull block 15, the movable rod 13, the connecting block 16 and the locking block 17 are an integrated structure.
[0029] In practical implementation, when the upper housing 2 and lower housing 1 need to be disassembled, the automatic cooling BMS control system only needs to pull the two sets of pull blocks 15 closer together, so that the pull blocks 15 drive the movable rod 13 to move. When the movable rod 13 moves, it will drive the connecting block 16 at the other end to move. At the same time, the movement of the movable rod 13 will cause the movable spring 14 in the groove of the fixed block 12 to be in a compressed state. The movement of the connecting block 16 will drive the locking block 17 on the other side to move. Since the protrusion 18 is inserted into the groove of the locking block 17, when the connecting block 16 drives the locking block 17 to move to the side of the protrusion 18, the protrusion 18 will separate from the locking block 17. The protrusion 18 is installed on the inner wall of the upper housing 2. The connecting block 16 is installed on the inner wall of the lower housing 1 through the movable rod 13 and the fixed block 12. When the locking block 17 separates from the protrusion 18, the upper housing 2 can be removed from the top of the lower housing 1, which facilitates the inspection and maintenance of the electronic components inside the lower housing 1.
[0030] Conversely, the upper housing 2 can be connected to the top of the lower housing 1, and then the pull block 15 can be released so that the pull block 15 does not exert any pulling force on the movable rod 13. At this time, under the reset action of the movable spring 14, the movable rod 13 can move in the opposite direction, and through the connecting block 16, it can drive the locking block 17 on the other side to move in the opposite direction. At this time, the locking block 17 will move to the outside of the protrusion 18 and fit on the outside of the protrusion 18. Through the cooperation of the locking block 17 and the protrusion 18, the upper housing 2 and the lower housing 1 can be quickly connected and fixed.
[0031] See Figure 2 , Figure 3 and Figure 4 As can be seen, during use, the two sets of pull blocks 15 can be pulled closer to each other according to the usage requirements, so that the pull blocks 15 drive the locking block 17 to move through the movable rod 13 and the connecting block 16. At this time, the locking block 17 will separate from the protrusion 18 on the inner wall of the upper housing 2. Without the docking action of the locking block 17 and the protrusion 18, the upper housing 2 can be quickly disassembled from the top of the lower housing 1, thereby facilitating the inspection and maintenance of the electronic components inside the lower housing 1.
[0032] In summary, when using this BMS control system with automatic cooling, the necessary electronic components can be installed inside the lower housing 1, then the upper housing 2 can be connected to the top of the lower housing 1, and the entire BMS controller can be fixed inside the vehicle by bolts to the lower housing 1. Finally, the corresponding wires can be connected to the vehicle through the interface 4, thereby realizing the function of monitoring and controlling the vehicle battery. This is the characteristic of the use of the BMS control system with automatic cooling. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
