[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a tooling fixture device for a battery pack base includes a box 1 that is snapped into the top plate of the battery pack base. The box 1 is a hollow structure with openings at the top and bottom. Ventilation slots 2 for accommodating battery heat are provided on both sides of the box 1. Multiple sets of vents 5 are provided on both sides of the box 1. A fan 4 is fixedly installed on one side of the vent 5.
[0027] The bottom of the housing 1 is fixedly equipped with a water-cooling structure for assisting the heat dissipation of the battery pack. The interior of the housing 1 is provided with a sandwich layer 3 that communicates with the water-cooling structure. The inner wall of the housing 1 is distributed with multiple sets of air vents 25, which are connected to the sandwich layer 3.
[0028] Clamping structures are provided on both sides of the inner wall of the housing 1. The clamping structures are used to stably clamp battery packs of different sizes.
[0029] In this embodiment, the battery packs of different sizes are first stabilized by a clamping structure according to the size of the battery pack. After clamping, the housing 1 and the bottom support plate of the battery pack are combined. During the use of the battery pack, the heat generated by the battery pack enters the housing 1 and the ventilation slot 2. The water cooling system at the bottom of the housing 1 is used to absorb the heat generated by the battery pack.
[0030] Meanwhile, since the internal interlayer 3 of the housing 1 is connected to the water-cooling structure, it can accommodate some cold air. The cold air is continuously discharged through the air vents 25, acting on the outside of the battery pack. Then, the fan 4 rotates to generate airflow. The airflow carries the cold air from the air vents 25 through the inside of the housing 1 and combines with multiple sets of adjacent parallel vents 5 to discharge hot air, achieving air convection heat dissipation and efficient heat dissipation for the battery pack.
[0031] As one implementation method, such as Figure 3 As shown, the water-cooling structure includes a water-cooling plate 15 fixedly installed at the bottom of the housing 1. Multiple sets of retaining rings 16 are fixedly installed inside the water-cooling plate 15. Metal pipes 17 for conveying cooling liquid are provided inside the multiple sets of retaining rings 16. Inlet pipes 18 and outlet pipes 19 are respectively connected to the two ends of the metal pipes 17. One end of the inlet pipe 18 and one end of the outlet pipe 19 extend to the outside of the water-cooling plate 15, and threaded connectors 20 are provided at the extended ends of the inlet pipe 18 and the outlet pipe 19.
[0032] The metal tube 17 has an S-shaped structure, and at least two sets of retaining rings 16 are provided. The retaining rings 16 are equidistantly distributed on the outside of the metal tube 17. Water circulation can be achieved by setting up an inlet pipe 18 and an outlet pipe 19 in conjunction with an external water pump and water tank structure. The S-shaped structure ensures the cooling effect while reducing water waste.
[0033] In this embodiment, threaded connectors 20 are provided for the inlet pipe 18 and outlet pipe 19 to provide a stable connection channel for the external water pump. Cooling liquid flows in the metal pipe 17 by injection, and the external retaining ring 16 can stabilize the metal pipe 17 in the water cooling plate 15. The metal pipe 17 is made of metal and has better heat conduction effect. With the cooling liquid in the metal pipe 17, the heat generated by the battery pack during use can be effectively removed. At the same time, the internal interlayer 3 of the housing 1 is connected to the water cooling plate 15 to accommodate some cold air, and the cold air is continuously discharged through the air hole 25.
[0034] As one implementation method, such as Figure 1 and Figure 2As shown, the clamping structure includes threaded openings 8 on both sides of the housing 1. An adjusting shaft 9 is threadedly connected inside the threaded opening 8. A threaded section 10 corresponding to the threaded opening 8 is opened on the outside of the adjusting shaft 9. A support cylinder 11 is rotatably sleeved on one end of the adjusting shaft 9. A clamping plate 12 for stabilizing the battery pack is fixedly installed on the outside of the support cylinder 11. An anti-slip pad 13 is provided on one side of the clamping plate 12.
[0035] Among them, the threaded port 8 is located between the two sets of fan components 4, and the other end of the adjusting shaft 9 is provided with a limiting port 14 for wrench insertion. After the stable battery pack is installed, the adjusting shaft 9 can be cut to increase the flatness of the appearance of the housing 1.
[0036] In this embodiment, the anti-slip pad 13 on one side of the clamping plate 12 can increase the friction between the clamping plate 12 and the battery pack, thereby increasing the stability of the clamping plate 12. During the clamping process, the limiting port 14, in conjunction with the external wrench, can rotate the adjusting shaft 9 to adjust the distance between adjacent clamping plates 12, thereby stabilizing battery packs of different sizes and increasing the compatibility between the clamping plate 12 and the battery pack.
[0037] As one implementation method, such as Figure 1 , Figure 3 As shown, at least four sets of vents 5 are provided, and multiple sets of vents 5 are arranged in a mirror symmetrical manner with respect to the center of the box body 1.
[0038] Among them, the fan component 4 includes a fixed cylinder 21 fixedly installed on one side of the housing 1. The fixed cylinder 21 corresponds to the vent 5. A dustproof net 6 is fixedly installed on one side of the fixed cylinder 21. A servo motor 22 is fixedly installed inside the fixed cylinder 21. The output shaft of the servo motor 22 is fixedly connected to a fixed block 23. Fan blades 24 are distributed around the outside of the fixed block 23.
[0039] In this embodiment, a servo motor 22 is provided to provide the power required for the rotation of the fixed block 23, thereby driving the fan blades 24 to rotate and generating airflow to assist in the cooling of the battery pack, thus forcing airflow.
[0040] As one implementation method, such as Figure 1 As shown, a cover plate 7 is hinged to one end of the fixed cylinder 21. A sealing gasket is provided on one side of the cover plate 7. By setting the cover plate 7, the ventilation channel of the box 1 can be closed when the device is idle. This not only effectively ensures the cleanliness of the internal space of the box 1, but also protects the cleanliness of the dustproof net 6, preventing the dustproof net 6 from being exposed to the outer surface for a long time when the box 1 is idle, thus preventing dust from adhering to the outer surface and affecting the normal use of the box 1.
[0041] Working principle: First, according to the size of the battery pack, the adjustment shaft 9 can be rotated by the limiting port 14 inside the adjustment shaft 9 in cooperation with the external wrench to adjust the distance between adjacent clamping plates 12, thus clamping and stabilizing battery packs of different sizes. The anti-slip pad 13 on one side of the clamping plate 12 can increase the friction between the clamping plate 12 and the battery pack, thereby increasing the stability of clamping. After clamping, during the use of the battery pack, the heat generated by the battery pack enters the housing 1 and the ventilation slot 2. The water cooling system at the bottom of the housing 1 is used to inject cooling liquid into the metal tube 17. The external retaining ring 16 can stabilize the metal tube 17 in the water cooling plate 15. With the help of the cooling liquid in the metal tube 17, the heat generated at the bottom of the battery pack during use can be effectively removed.
[0042] Meanwhile, the internal interlayer 3 of the housing 1 is connected to the water cooling plate 15 to accommodate some cold air. The cold air is continuously discharged through the air vent 25 and acts on the outside of the battery pack. Then, the servo motor 22 in the fan component 4 provides the power required for the rotation of the fixed block 23, thereby driving the fan blades 24 to rotate and generate airflow to assist in the cooling of the battery pack. The forced airflow generates airflow, which carries the cold air through the air vent 25, passes through the inside of the housing 1, and combines with the adjacent parallel sets of vents 5 to discharge hot air, realizing air convection cooling and efficient cooling of the battery pack.
