Description

Technical Field

[0001] This utility model relates to the field of battery temperature control technology, specifically to a liquid cooling module structure for a high-performance power battery for two-wheeled vehicles. Background Technology

[0002] With the development of two-wheeled electric vehicles, the requirements for power and range are constantly increasing. In order to improve the range of two-wheeled electric vehicles, some two-wheeled electric vehicles use high-performance power batteries in their power components, and equip the high-performance power batteries with liquid cooling systems to cool them down during operation.

[0003] In the prior art, patent document with publication number CN213905448U discloses a power battery liquid cooling device and power battery system. During assembly, multiple plates need to be combined to form a housing for the battery. When the battery is cold-cut, only the water-cooling plate body below the battery and the aluminum profile end plates at both ends can have coolant flowing, which results in complicated assembly and low battery cooling efficiency.

[0004] The patent document with publication number CN213905457U discloses a power battery cooling structure. This technical solution also has the above-mentioned technical problems. In this technical solution, coolant flows in only two wall plates and one bottom plate, which leads to complicated assembly and low battery cooling efficiency.

[0005] High-performance battery packs for two-wheeled electric vehicles are typically 60V or 72V, and usually consist of 5 or 6 batteries. Therefore, using a fixed-volume housing to hold the batteries is suitable for different two-wheeled electric vehicles and can improve assembly efficiency. Utility Model Content

[0006] The main objective of this invention is to provide a liquid-cooled module structure that is easy to assemble and can effectively control the temperature of the battery.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: A high-performance power battery liquid-cooled module structure for two-wheeled vehicles includes a base plate with an inner cavity. A rectangular upper frame is fixed to the upper part of the base plate, and an annular cavity is formed inside the upper frame. The base plate is fixed to the lower end of the upper frame, and the inner cavity communicates with the annular cavity. A liquid inlet component is fixedly connected to one side of the base plate, and a liquid outlet component is fixedly connected to the upper end of the upper frame. The liquid outlet component is located above the liquid inlet component. Multiple partitions are arranged sequentially in the upper frame above the base plate, and a battery is placed between two adjacent partitions. A limiting component is provided in one end of the upper frame, and the limiting component abuts against a partition on one side. A cover plate is detachably fixed to the upper end of the upper frame, and a wire hole is formed at one end of the cover plate, through which a cable connected to the battery passes.

[0008] Specifically, the bottom plate has multiple first outlet holes on its left end, and the upper frame has a second outlet hole that corresponds to and is connected to the first outlet holes on its lower end.

[0009] Specifically, the liquid outlet assembly includes multiple outlet tubes fixed to the right end of the upper frame, the outlet tubes being connected to the annular cavity, and the multiple outlet tubes being fixedly connected to the upper manifold.

[0010] Specifically, multiple inlet pipes are fixed to the right end of the base plate, the inlet pipes are connected to the inner cavity, and the multiple inlet pipes are fixedly connected to the lower manifold.

[0011] Specifically, the upper frame has multiple mounting holes at its upper end, and screws are threaded into the mounting holes after passing through the holes in the cover plate.

[0012] Specifically, the limiting component includes two limiting units, which are symmetrically arranged on the left and right. Each limiting unit includes an ear plate fixed to the inner side of the rear side wall of the upper frame. A swing rod is rotatably connected to the ear plate. The front end of the swing rod is inclined towards the center of the upper frame. An elastic plate is fixed to the front end of the swing rod. The elastic plate is tightly pressed against a partition on one side. A fixing plate is fixed to one side of the ear plate. A bolt is threadedly connected to the fixing plate. One end of the bolt is tightly pressed against the swing rod.

[0013] Specifically, the elastic sheet is inverted V-shaped, with the front part of the elastic sheet tightly abutting against the partition, and the rear part of the elastic sheet fixed to the front end of the swing arm.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the interconnected design of the bottom plate's inner cavity and the upper frame's annular cavity, combined with the liquid cooling circulation paths of the inlet and outlet components, the coolant can evenly cover the battery area, achieving efficient heat exchange. This solves the potential problem of battery overheating in two-wheeled vehicles under high-speed or high-temperature conditions, ensuring stable operation of the power battery and extending its service life.

[0015] 2. The separator effectively separates adjacent batteries, providing insulation and physical buffer to prevent short circuits or collision damage; the cover's encapsulation structure improves overall sealing and dust and moisture protection capabilities, while the limiting components further absorb vibration and impact, preventing batteries from shifting or colliding with each other during vehicle operation, significantly reducing safety risks.

[0016] 3. The adjustable design of the limiting components allows for a tight fit between the battery and separator, accommodating different battery sizes; the rigid connection between the upper frame and the base plate ensures overall module stability and improves assembly efficiency. This enhances the system's durability on bumpy roads or under frequent start-stop conditions, reducing maintenance requirements.

[0017] 4. The modular design facilitates quick assembly and battery replacement; the wire hole design makes cable laying convenient and reduces on-site construction complexity. The limit component allows for battery positioning simply by turning the bolt, reducing the difficulty of daily maintenance.

[0018] 5. Combining liquid cooling and mechanical fixing mechanisms, this structure can efficiently cope with the space constraints and dynamic loads unique to two-wheeled vehicles, such as heat accumulation and mechanical stress during high-speed cornering or rapid acceleration. This allows the battery module to maintain high-performance output even in harsh environments, supporting the electric vehicle's range and power stability. Attached Figure Description

[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] Example 1: Refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a liquid-cooled module structure for a high-performance power battery for two-wheeled vehicles includes a base plate 2, an inner cavity 20 inside the base plate 2, a rectangular upper frame 1 fixed to the upper end of the base plate 2, an annular cavity 21 inside the upper frame 1, the base plate 2 fixed to the lower end of the upper frame 1, the inner cavity 20 communicating with the annular cavity 21, a liquid inlet assembly fixedly connected to one side of the base plate 2, and a liquid outlet assembly fixedly connected to the upper end of the upper frame 1, the liquid outlet assembly being located above the liquid inlet assembly.

[0028] Multiple partitions 4 are arranged sequentially inside the upper frame 1 above the base plate 2. A battery 3 is placed between two adjacent partitions 4. A cover plate 6 is detachably and fixedly connected to the upper end of the upper frame 1. A wire hole 13 is opened at one end of the cover plate 6, and the cable connected to the battery 3 passes through the wire hole 13.

[0029] The bottom plate 2 has multiple first outlet holes 14 on its left end, and the upper frame 1 has a second outlet hole 15 on its lower end that corresponds to and is connected to the first outlet holes 14.

[0030] The liquid outlet assembly includes multiple outlet tubes 17 fixed to the right end of the upper frame 1. The outlet tubes 17 are connected to the annular cavity 21, and the multiple outlet tubes 17 are fixedly connected to the upper manifold 16.

[0031] Multiple inlet pipes 18 are fixed at the right end of the base plate 2. The inlet pipes 18 are connected to the inner cavity 20, and the multiple inlet pipes 18 are fixedly connected to the lower manifold 19.

[0032] The upper frame 1 has multiple mounting holes 5 at its upper end. Screws 7 pass through the holes on the cover plate 6 and are threaded into the mounting holes 5.

[0033] In this embodiment, the upper frame 1 is fixedly connected to the bottom plate 2. When installing the battery 3, multiple partitions 4 are placed inside the upper frame 1, and the battery 3 is installed between two adjacent partitions 4. The partitions 4 can separate two adjacent batteries 3 and can provide insulation and buffer protection for the battery 3. Then, the cover plate 6 is used to encapsulate the battery 3 and the partitions 4 between the upper frame 1 and the bottom plate 2, and the cable connected to the battery 3 passes through the wire hole 13.

[0034] When battery 3 is working, coolant enters the inner cavity 20 through the lower manifold 19 and multiple inlet pipes 18. The coolant in the inner cavity 20 enters the annular cavity 21 through the first outlet 14 and the second outlet 15. The coolant in the annular cavity 21 is discharged through multiple outlet pipes 17 and the upper manifold 16.

[0035] The coolant can flow in the inner cavity 20 and the annular cavity 21, which can improve the cooling efficiency of the battery 3.

[0036] Example 2: Based on Example 1, referring to... Figure 1 and Figure 2 As shown, a limiting component is provided inside one end of the upper frame 1, and the limiting component is in close contact with the partition 4 on one side.

[0037] The limiting component includes two limiting units, which are arranged symmetrically on the left and right sides.

[0038] The limiting unit includes an ear plate 8 fixed to the inner side of the rear side wall of the upper frame 1. A swing rod 9 is rotatably connected to the ear plate 8. The front end of the swing rod 9 is inclined towards the center of the upper frame 1. An elastic piece 10 is fixed to the front end of the swing rod 9. The elastic piece 10 is tightly pressed against the partition plate 4 on one side. A fixing plate 11 is fixed to one side of the ear plate 8. A bolt 12 is threadedly connected to the fixing plate 11. One end of the bolt 12 is tightly pressed against the swing rod 9.

[0039] The elastic plate 10 is inverted V-shaped, with the front part of the elastic plate 10 tightly abutting against the partition 4, and the rear part of the elastic plate 10 fixed to the front end of the swing rod 9.

[0040] In this embodiment, by setting a limiting component, the multiple batteries 3 and the partition 4 in the upper frame 1 can be stabilized, so as to avoid the batteries 3 colliding with each other during the movement of the two-wheeled electric vehicle.

[0041] When the battery 3 is located between two adjacent partitions 4, the bolt 12 is rotated. The bolt 12 causes the swing arm 9 to drive the elastic plate 10 to swing away from the center of the upper frame 1. The elastic plate 10 is gradually compressed, and multiple batteries 3 and multiple partitions 4 are pressed together, thereby realizing the positioning of the battery 3 and the partition 4.

[0042] During the movement of the two-wheeled electric vehicle, the battery 3 can compress the elastic sheet 10 and cause the elastic sheet 10 to deform, and the elastic sheet 10 can buffer and protect the battery 3.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
