It can achieve higher voltage and capacity, facilitates the installation, connection and management of battery modules, and provides necessary protection and monitoring functions. A base plate is required when installing a battery pack, so a battery pack base plate is needed.

[0003] When operators are fixing and installing battery packs, they often use corresponding battery pack base plates. Although the existing base plates can achieve the purpose of installation, in actual use they are mostly installed at the bottom of the car. Due to the lack of a buffer mechanism, foreign objects may damage the base plate and battery pack when they are impacted. In addition, the heat dissipation method for the battery pack is singular and the heat dissipation performance is poor. Utility Model Content

[0004] The purpose of this utility model is to provide a battery pack base plate to solve the problem mentioned in the background art. When operators fix and install battery packs, they often use corresponding battery pack base plates. Although existing base plates can achieve the purpose of installation, in actual use, they are mostly installed at the bottom of the car. Due to the lack of a buffer mechanism, when foreign objects impact them, the base plate and battery pack may be damaged. In addition, the heat dissipation method for the battery pack is singular and the heat dissipation performance is poor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery pack base plate, comprising a base plate, with vertical tubes fixedly installed at both ends of the bottom of the base plate, a return spring fixedly installed at the top of the inside of each vertical tube, a movable plate fixedly installed at the bottom of each return spring located inside the vertical tube, a pressure rod movably installed at the bottom of each vertical tube, the top of the pressure rod penetrating the vertical tube and fixedly connected to the bottom of the movable plate, a buffer plate fixedly installed at the bottom of the pressure rod, vertical grooves being formed on both sides of each vertical tube, a connecting rod movably installed inside each vertical groove, one side of the connecting rod being fixedly connected to one side of the movable plate, and a fixing block fixedly installed on the other side of the connecting rod.

[0006] Preferably, the bottom of the base plate has grooves on both sides, and a round rod is fixedly installed inside each groove. A slider is movably sleeved on the surface of each round rod. A buffer spring is fixedly installed between each slider and the groove. The inner surface of the buffer spring is movably connected to the outer surface of the round rod, and a moving rod is fixedly installed at the bottom of each slider.

[0007] Preferably, the bottom plate has a liquid storage tank inside, and heat dissipation holes are provided at equal intervals on the top of the bottom plate.

[0008] Preferably, a connecting groove is provided on one side of the base plate, and a sealing rod is movably installed inside the connecting groove.

[0009] Preferably, each side of the base plate is provided with a mounting groove, and a mounting plate is movably installed inside each mounting groove, with one end of the mounting plate being fixedly connected to one end of the closing rod.

[0010] Preferably, bolts are rotatably mounted on one side of the mounting plate, and one side of the bolts penetrates the mounting plate and extends into the interior of the base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In daily use, when a foreign object impacts the buffer plate, the buffer plate causes the pressure rod to slide. The pressure rod then causes the moving plate to slide inside the vertical tube, which in turn squeezes and compresses the return spring. At this time, the moving plate causes the connecting rod to slide inside the vertical groove, which in turn causes the fixed block to slide. Simultaneously, the outer surface of the fixed block continuously squeezes the outer surface of the moving rod, which in turn causes the slider to slide inside the groove and on the surface of the round rod. The slider then squeezes and compresses the buffer spring, thus buffering the impact force.

[0013] In daily use, this type of battery pack base plate allows the operator to place coolant into the reservoir through the connecting slot, then place the sealing rod inside the connecting slot. At this time, the mounting plate will be placed inside the mounting slot. Then, the bolts are turned and screwed into the mounting plate and the base plate to install the coolant. When the battery pack heats up, the coolant inside the reservoir can absorb the heat, and the heat dissipation holes can also dissipate heat, thereby improving the heat dissipation performance.

[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 1-8This utility model provides a technical solution: a battery pack base plate, including a base plate 1. Vertical tubes 2 are fixedly installed at both ends of the bottom of the base plate 1. Return springs 3 are fixedly installed at the top of the interior of each vertical tube 2. Movable plates 4 located inside the vertical tubes 2 are fixedly installed at the bottom of each return spring 3. When the movable plates 4 slide, they press and compress the return springs 3. The outer surface of the movable plates 4 is movably connected to the inner surface of the vertical tubes 2. Both the outer surface of the movable plates 4 and the inner surface of the vertical tubes 2 are smooth. A pressure rod 5 is movably installed at the bottom of each vertical tube 2. The top of the pressure rod 5 penetrates the vertical tube 2 and is fixedly connected to the bottom of the movable plates 4. When the pressure rod 5 slides, it causes the movable plates 4 to slide. A buffer plate 6 is fixedly installed at the bottom of the pressure rod 5. When the buffer plate 6 slides, it causes the pressure rod 5 to slide. Vertical grooves 7 are opened on both sides of the vertical tubes 2. Movable plates 4 are installed inside the vertical grooves 7. The base plate 1 is equipped with a connecting rod 8, one side of which is fixedly connected to one side of the movable plate 4. When the movable plate 4 slides, it will cause the connecting rod 8 to slide inside the vertical groove 7. The other side of the connecting rod 8 is fixedly installed with a fixing block 9. When the connecting rod 8 slides, it will cause the fixing block 9 to slide. The bottom of the base plate 1 has a sliding groove 10 on both sides. A round rod 11 is fixedly installed inside the sliding groove 10. A slider 12 is movably sleeved on the surface of the round rod 11. A buffer spring 13 is fixedly installed between the slider 12 and the sliding groove 10. When the slider 12 slides inside the sliding groove 10 and on the surface of the round rod 11, it will squeeze and compress the buffer spring 13. The inner surface of the buffer spring 13 is movably connected to the outer surface of the round rod 11. The bottom of the slider 12 is fixedly installed with a movable rod 14. When the movable rod 14 slides, it will cause the slider 12 to slide.

[0025] The base plate 1 has a liquid storage tank 15 inside, which can store coolant. The top of the base plate 1 has heat dissipation holes 21 at equal intervals, which can dissipate heat. One side of the base plate 1 has a connecting groove 16, and a sealing rod 17 is movably installed inside the connecting groove 16. The sealing rod 17 can close the connecting groove 16. One side of the base plate 1 has a mounting groove 18, and a mounting plate 19 is movably installed inside the mounting groove 18. The mounting groove 18 and the mounting plate 19 are adapted to each other, and one end of the mounting plate 19 is fixedly connected to one end of the sealing rod 17. When the sealing rod 17 slides, it will drive the mounting plate 19 to slide. One side of the mounting plate 19 is rotatably installed with a bolt 20, and one side of the bolt 20 passes through the mounting plate 19 and extends into the interior of the base plate 1. The design of the bolt 20 can make the connection between the mounting plate 19 and the base plate 1 tighter, thereby making the sealing rod 17 more stable.

[0026] Working principle: First, the operator places coolant into the reservoir 15 through the connecting groove 16, and then places the sealing rod 17 into the connecting groove 16. At this time, the mounting plate 19 will be placed into the mounting groove 18. Then, the bolt 20 is rotated and screwed into the mounting plate 19 and the base plate 1. The coolant in the reservoir 15 can absorb the heat generated by the battery pack and dissipate it through the heat dissipation hole 21. Second, when a foreign object impacts the buffer plate 6, the buffer plate 6 will cause the pressure rod 5 to slide. Then, the pressure rod 5 will cause the moving plate 4 to slide inside the vertical tube 2, thereby squeezing and compressing the reset spring 3. At this time, the moving plate 4 will cause the connecting rod 8 to slide inside the vertical groove 7. Then, the connecting rod 8 will cause the fixing block 9 to slide. At the same time, the outer surface of the fixing block 9 will continuously squeeze the outer surface of the moving rod 14. Then, the moving rod 14 will cause the slider 12 to slide inside the sliding groove 10 and on the surface of the round rod 11. Then, the slider 12 will squeeze and compress the buffer spring 13, thus buffering the impact force.

[0027] 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.
