Description

Technical Field

[0001] This utility model relates to the field of energy storage power technology, and in particular to a portable energy storage device. Background Technology

[0002] Traditional energy storage power supply casings are generally made of metal materials such as aluminum alloys. However, due to the increasing price of alloys, the casings of some energy storage power supplies have been redesigned to be made entirely of plastic to reduce costs. However, the plastic material reduces heat transfer efficiency and natural heat dissipation efficiency, which can easily lead to a series of risks due to poor heat dissipation during use. Utility Model Content

[0003] This invention provides a portable energy storage device to overcome the problems of high cost of traditional energy storage power supply casings and inconvenience in battery installation and removal.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Portable energy storage devices, including:

[0006] The device comprises an upper shell, a middle shell, a lower shell, and a battery compartment. The lower shell has an inner cavity for housing the battery compartment and a first heat dissipation hole communicating with the inner cavity. The middle shell is disposed on the lower shell and has a heat dissipation device communicating with the inner cavity. The upper shell is disposed on the middle shell and has a second heat dissipation hole communicating with the heat dissipation device.

[0007] As described above, the portable energy storage device includes two boxes arranged opposite each other. Each box includes a main body and connecting edges on both sides of the main body. The main body and the connecting edges are integrally bent from sheet metal. The connecting edges of the two boxes are connected by fasteners.

[0008] As described above, the portable energy storage device has a third heat dissipation hole on the middle shell, and the heat dissipation device is a fan, which is mounted on the third heat dissipation hole.

[0009] In the portable energy storage device described above, the upper shell, middle shell, and / or lower shell are made of plastic.

[0010] In the portable energy storage device described above, the battery box is detachably connected to the middle shell.

[0011] In the portable energy storage device described above, the upper shell and the middle shell are connected by fasteners.

[0012] As described above, the portable energy storage device has a positioning slot on the inner side wall of the lower shell and a positioning strip on the middle shell for insertion into the positioning slot.

[0013] As described above, the portable energy storage device has a tactile switch and a socket electrically connected to the battery box on its upper casing.

[0014] As described above, the portable energy storage device also has limiting structures at the four corners of the middle shell. When the middle shell is installed on the lower shell, the limiting structures restrict the middle shell within the lower shell and limit the movement of the middle shell in the length and width directions of the lower shell.

[0015] As described above, the portable energy storage device has a central wiring port in the middle of the shell, a fan wiring port next to the heat dissipation device on the shell, and an edge wiring port along the edge of the shell.

[0016] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0017] The outer shell is divided into an upper shell, a middle shell, and a lower shell. The middle shell is equipped with heat dissipation holes and a fan to dissipate the heat generated by the battery during operation and improve the overall heat dissipation efficiency. Therefore, the upper, middle, and lower shells can be made of plastic materials with relatively low heat transfer and natural heat dissipation efficiency, which reduces costs.

[0027] 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.

[0028] Example:

[0029] like Figures 1 to 7 The portable energy storage device shown includes an upper shell 1, a middle shell 2, a lower shell 3, and a battery compartment 4. The lower shell 3 has an inner cavity 31 for housing the battery compartment 4, and a first heat dissipation hole 32 communicating with the inner cavity 31. The middle shell 2 is disposed on the lower shell 3 and has a heat dissipation device 21 communicating with the inner cavity 31. The upper shell 1 is disposed on the middle shell 2 and has a second heat dissipation hole 11 communicating with the heat dissipation device 21. The heat dissipation device 21 helps dissipate heat and can improve the overall heat dissipation efficiency.

[0030] Furthermore, the battery box 4 includes two opposing box bodies 41. Each box body 41 includes a main body 411 and connecting edges 412 on both sides of the main body 411. The main body 411 and the connecting edges 412 are integrally bent from sheet metal. The connecting edges 412 of the two box bodies 41 are connected by fasteners. The shape of the box body 41 can be U-shaped, semi-circular, or square. The design of the box body 41 makes the installation of the battery box 4 more convenient, and the integral bending technology of sheet metal makes the processing of the battery box 4 easier.

[0031] Furthermore, the middle shell 2 is provided with a third heat dissipation hole 22, and the heat dissipation device 21 is a fan 211, which is disposed on the third heat dissipation hole 22. The third heat dissipation hole 22 can be a large hole that is circular, square, or polygonal, or it can be a group of holes composed of multiple circular, square, or polygonal holes. The arrangement of the third heat dissipation hole 22 can enhance the airflow rate of the air blown out by the fan 211, thereby improving the heat dissipation efficiency.

[0032] Furthermore, since the middle shell 2 is provided with a third heat dissipation hole 22 and a fan 211 for heat dissipation, the heat generated by the battery during operation can be dissipated. Therefore, the upper shell 1, middle shell 2, and / or lower shell 3 can be made of lower-cost plastics. This reduces costs while improving heat dissipation efficiency.

[0033] Furthermore, the battery box 4 is detachably connected to the middle shell 2. The connection method can be riveting, screwing, etc., making installation convenient.

[0034] Furthermore, the upper shell 1 and the middle shell 2 are connected by fasteners. Specific connection methods can include riveting, screwing, etc., making installation convenient.

[0035] Furthermore, the inner wall of the lower shell 3 is provided with a positioning slot 33, and the middle shell 2 is provided with a positioning strip 23 for insertion into the positioning slot 33. The positioning strip 23 is located on the side of the middle shell 2 near the lower shell 3 and corresponds one-to-one with the positioning slot 33. When connecting the middle shell 2 and the lower shell 3, the positioning strip 23 is simply aligned with the positioning slot 33 and snapped into place, making the connection convenient.

[0036] Furthermore, the upper shell 1 is provided with a tactile switch 12 and a socket 13 electrically connected to the battery box 4 for ease of use.

[0037] Furthermore, the middle shell 2 is provided with limiting structures 24 at its four corners. When the middle shell 2 is installed on the lower shell 3, the limiting structures 24 restrict the movement of the middle shell 2 in the length and width directions of the lower shell 3. The design of the limiting structures 24 not only prevents the middle shell 2 from moving within the lower shell 3, but also facilitates installation. After aligning the limiting structures 24 at the four corners, the battery box 4 can be easily installed inside the lower shell 3.

[0038] Furthermore, the middle shell 2 has a central wiring port 25 in its center, a fan wiring port 26 next to the heat dissipation device 21 on the middle shell 2, and an edge wiring port 27 along its edge. These different wiring ports allow wires for different purposes to pass through, preventing messy wiring and facilitating the installation of the battery box 4 and the middle shell 2.

[0039] Furthermore, during installation, the battery box 4 is first fixedly connected to the middle shell 2. After the wiring is laid out, the upper shell 1 is fixedly connected to the middle shell 2, and then the entire assembly is placed into the lower shell 3. The connection between the middle shell 2 and the lower shell 3 makes it easier to assemble and disassemble the battery box 4, and the handle 14 of the upper shell 1 can be easily lifted and placed during assembly and disassembly, facilitating the installation of the battery box 4 into the lower shell 3.

[0040] The working principle of this embodiment is as follows:

[0041] The outer casing is divided into an upper shell, a middle shell, and a lower shell. The middle shell has heat dissipation holes and a fan to dissipate the heat generated by the battery during operation, improving overall heat dissipation efficiency. Therefore, the upper, middle, and lower shells can be made of plastic materials with relatively low heat transfer and natural heat dissipation efficiency, reducing costs. The fan airflow can pass through the upper, middle, and lower shells, forming an airflow channel within them, further improving overall heat dissipation efficiency.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
