Description

Technical Field

[0001] The present application relates to the technical field of energy storage power supplies, and in particular to an energy storage power supply structure. Background Art

[0002] Power batteries are the power source for tools, often referring to the storage batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. They are also known as energy storage power sources. Power batteries are a core component of new energy vehicles and a key direction for future energy transformation.

[0003] In related technologies, the energy storage power supply structure includes a housing, a top cover, and a battery pack. The battery pack is fixedly mounted within the housing, and the top cover is detachably connected to the housing. The housing and top cover work together to protect the battery pack. However, there is a gap at the connection between the top cover and the housing, which is prone to water ingress. Furthermore, the housing is relatively rigid, which can easily damage the internal battery pack in the event of a fall. Utility Model Content

[0004] In order to reduce the risk of water ingress into the energy storage power supply structure and prevent falls and collisions, the present application provides an energy storage power supply structure.

[0005] The energy storage power supply structure provided in this application adopts the following technical solution:

[0006] A storage power supply structure includes a shell, an upper cover and a battery pack. The battery pack is arranged in the shell. The upper cover is detachably connected to the shell. A waterproof soft rubber layer is provided on the outer side walls of the upper cover and the shell. The waterproof soft rubber layers at the connection between the upper cover and the shell abut against each other.

[0007] By adopting the above technical solution, the waterproof soft rubber layers at the connection between the upper cover and the shell abut against each other and form an interference fit, thereby improving the sealing and waterproof properties; at the same time, the soft rubber layer can also buffer and absorb shock, playing a role in preventing falls and collisions.

[0008] Optionally, first mounting protrusions are provided at four corners of a side of the upper cover close to the shell, and a first groove for plugging the first mounting protrusions is provided on a side of the shell close to the upper cover;

[0009] A second groove is formed between adjacent first mounting protrusions, a second mounting protrusion is formed on a side of the shell close to the upper cover and facing the upper cover, and the second mounting protrusion is inserted into the second groove.

[0010] By adopting the above technical solution, when connecting the upper cover and the shell, it is helpful to position and limit the upper cover and the shell, thereby improving the convenience and stability of the connection between the upper cover and the shell.

[0011] Optionally, the battery pack includes a battery skeleton structure, an inverter and a protection plate, wherein the inverter and the protection plate are fixedly arranged at two ends of the battery skeleton structure, respectively, and the inverter is closer to the upper cover than the protection plate.

[0012] Optionally, an air inlet is provided on one side of the shell, and air outlets are provided on both sides of the shell adjacent to the air inlet. Shutters are provided at both the air inlet and the air outlet, and the blades of the shutters are arranged to face away from the upper cover.

[0013] By adopting the above technical solution, a one-side air intake and two-side air outlet method is adopted. Air is taken in through the shutters on the air inlet side, passes through the battery skeleton structure, and discharges internal heat during charging and discharging, and then discharged from the air outlets on both sides, which effectively dissipates heat for the protection board and inverter, thereby improving the performance of the energy storage power supply structure.

[0014] Optionally, a middle portion of the shell side wall is recessed toward the interior of the shell, and the shutter is arranged at the recessed portion of the shell side wall.

[0015] By adopting the above technical solution, the protruding setting of the blinds is avoided, which facilitates the subsequent installation of the energy storage power supply structure and improves the overall appearance; in addition, when the staff takes the energy storage power supply structure of this application, it helps to improve comfort.

[0016] Optionally, buckles are fixedly connected to opposite side walls of the shell, and the buckles are used to connect to the whole machine used in conjunction with the energy storage power supply structure.

[0017] By adopting the above technical solution, the clips on both sides are installed on the whole machine used in conjunction with the energy storage power supply structure of this application to play a fixing role. The battery pack can withstand vibration during charging and discharging, prevent falling off, and ensure product safety.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The waterproof soft rubber layer at the connection between the upper cover and the shell abuts against each other, forming an interference fit, which improves the sealing and waterproofness; at the same time, the soft rubber layer can also buffer and reduce shock, playing a role in preventing falls and collisions;

[0020] 2. The system adopts a one-side air intake and two-side air outlet mode. Air enters through the louvers on the air inlet side, passes through the battery skeleton structure, and removes internal heat during charging and discharging. The heat is then discharged from the air outlets on both sides, effectively dissipating heat for the protection board and inverter, thereby improving the performance of the energy storage power supply structure.

[0021] 3. By setting the buckles, the buckles on both sides are fixed on the whole machine used in conjunction with the energy storage power structure of this application, which plays a fixing role. The battery pack can withstand vibration during charging and discharging, prevents it from falling off, and ensures product safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The embodiment of the present application discloses an energy storage power supply structure. Figure 1-2 The energy storage power supply structure includes a housing 7, an upper cover 2, and a battery pack. The battery pack is disposed within the housing 7. The upper cover 2 is detachably connected to the housing 7 via bolts 1. The upper cover 2 and the housing 7 are supported by plastic. A transparent waterproof soft rubber layer is bonded to the outer walls of the upper cover 2 and the housing 7. The waterproof soft rubber layer abuts against each other at the connection between the upper cover 2 and the housing 7. The waterproof soft rubber layer abuts against each other at the connection between the upper cover 2 and the housing 7, forming an interference fit to improve sealing and waterproofing. The soft rubber layer also provides shock absorption and prevents falls.
