Technical Field

[0001] The utility model relates to the technical field of lithium - ion battery energy storage devices, in particular to a portable lithium - ion battery energy storage device. Background Art

[0002] Lithium - ion batteries, commonly known as rocking - chair batteries, refer to the general term of batteries with lithium - ion intercalation compounds as the positive electrode materials. They are secondary batteries (rechargeable batteries), mainly relying on the movement of lithium ions between the positive and negative electrodes to work. Currently, lithium - ion batteries can be combined to form a battery energy storage device, enabling the lithium - ion battery energy storage device to be carried outdoors for use.

[0003] Existing lithium - ion battery energy storage devices usually have a handle set on the outer shell. The handle can be used to make the energy storage device portable outdoors. In addition, positive and negative electrode posts are also set on the outer shell of the energy storage device for power connection operations when used outdoors.

[0004] Currently, the positive and negative electrode posts of the energy storage device are directly exposed outside, which results in a lack of practical protection for the positive and negative electrode posts. During outdoor mobile use, the surfaces of the positive and negative electrode posts are easily damaged, and other things are easily attached to the surfaces, causing poor contact when connecting electricity. At the same time, in rainy days, the positive and negative electrode posts cannot be directly exposed for use on the energy storage device, so that users must also pay attention to the rain - proof effect of the energy storage device, bringing inconvenience to users. Summary of the Utility Model

[0005] In view of the problems that the electrode posts on the above - mentioned energy storage device lack protection and cannot be used in the rain, the present utility model is proposed.

[0006] To solve the above - mentioned technical problems, the present utility model provides the following technical solutions: A portable lithium - ion battery energy storage device, including a battery energy storage device body, a handle set on the battery energy storage device body, and a protective pad sleeved on the handle;

[0007] The battery energy storage device body is provided with electrode posts, and a protection mechanism is arranged outside the electrode posts. The protection mechanism surrounds the electrode posts and forms protection for them;

[0008] The protection mechanism includes a protective cover, anti - slip patterns set on the protective cover, and a connecting ring installed on the battery energy storage device body.

[0009] As a preferred solution of the portable lithium - ion battery energy storage device of the present utility model, among them: The protective cover covers outside the electrode posts, and there is no contact between them. The protective cover is connected to the connecting ring by screwing.

[0010] As a preferred embodiment of the portable lithium-ion battery energy storage device of the present utility model, the following is provided: a through groove for the wire to pass through is formed on the pole column, and a lower pressing plate is arranged in the through groove.

[0011] As a preferred embodiment of the portable lithium-ion battery energy storage device of the present utility model, the following is provided: a movable rod penetrating through the pole column is connected to the lower pressing plate, and an elastic sheet is sleeved on the outer wall of the movable rod.

[0012] As a preferred embodiment of the portable lithium-ion battery energy storage device of the present utility model, the following is provided: an extension ring is movably connected to one side of the protective cover facing the connection ring, and a first tooth opening is formed on the extension ring.

[0013] As a preferred embodiment of the portable lithium-ion battery energy storage device of the present utility model, the following is provided: a first fitting pad is arranged in the first tooth opening, and the first fitting pad is connected to the extension ring.

[0014] As a preferred embodiment of the portable lithium-ion battery energy storage device of the present utility model, the following is provided: a second tooth opening is formed on the connection ring, and a second fitting pad is placed in the second tooth opening, and the second fitting pad is connected to the connection ring.

[0015] Advantages of the present utility model:

[0016] First, the protective cover can protect the pole column, preventing the pole column from being damaged when carried outdoors, thus ensuring the normal use of the battery energy storage device, avoiding poor contact during power connection, and when the protective cover is connected to the connection ring, the protective cover approaching the connection ring can press down the movable rod, and the movable rod drives the lower pressing plate to move, and the lower pressing plate can press the wire in the through groove, so that the wire can be prevented from detaching from the pole column and the connection between the wire and the pole column can be strengthened;

[0017] Second, as the distance between the protective cover and the connection ring shortens, the first tooth opening and the second tooth opening approach each other to squeeze the wire, so that a seal is formed at the position where the wire contacts the protective cover, thus preventing rainwater from entering the interior of the protective cover and causing a short circuit of the wire when the pole column is powered.

[0025] Embodiment 1

[0026] Refer to Figures 1-3 , which is the first embodiment of the present utility model, provides a portable lithium-ion battery energy storage device, including a battery energy storage device body 1, a handle 11 provided on the battery energy storage device body 1, and a protection pad 12 sleeved on the handle 11; the handle 11 is rotatably connected to the battery energy storage device body 1, and the battery energy storage device body 1 can be conveniently lifted by using the handle 11, so as to realize the portability of the energy storage device, and the protection pad 12 can buffer and protect the user's palm.

[0027] A terminal post 13 is provided on the battery energy storage device body 1, and a protection mechanism is provided outside the terminal post 13. The protection mechanism surrounds the terminal post 13 and forms protection for it;

[0028] The protection mechanism includes a protective cover 2, an anti-slip pattern 21 provided on the protective cover 2, and a connecting ring 22 installed on the battery energy storage device body 1. The connecting ring 22 is fixedly connected to the battery energy storage device body 1, and the outer wall of the connecting ring 22 is provided with threads.

[0029] The protective cover 2 covers the pole 13 without contacting each other, and the protective cover 2 is screwed to the connecting ring 22. When the protective cover 2 is screwed to the connecting ring 22, the protective cover 2 can protect the pole 13 to prevent the pole 13 from being damaged when carried outdoors, thereby ensuring that the battery energy storage device can be used normally and avoiding poor contact when connected to the power supply. Anti-slip grooves 21 are provided on the protective cover 2 so that the user can rotate the protective cover 2.

[0030] The pole 13 is provided with a through slot 1301 for the wire to pass through, wherein a lower pressing plate 1302 is arranged in the through slot 1301 .

[0031] The lower pressing plate 1302 is connected with a movable rod 1303 penetrating the pole 13, and an elastic sheet 1304 is sleeved on the outer wall of the movable rod 1303. The movable rod 1303 is arranged in a T-shape, and when the movable rod 1303 moves downward, the elastic sheet 1304 can be deformed by accumulating force, and when power is turned on, the wire is wound around the pole 13 and allowed to pass through the through slot 1301.

[0032] When the protective cover 2 is connected to the connecting ring 22, the protective cover 2 close to the connecting ring 22 can press the movable rod 1303 downward, and the movable rod 1303 moves with the lower pressure plate 1302, and the lower pressure plate 1302 can press the wires in the through groove 1301, thereby preventing the wires from detaching from the pole 13 and strengthening the connection between the wires and the pole 13.

[0033] Example 2

[0034] Reference Figures 1-4 , which is the second embodiment of the utility model, is different from the first embodiment in that: the protective cover 2 is movably connected to the side of the connecting ring 22 with an extension ring 201, wherein the extension ring 201 is provided with a first tooth opening 202. The protective cover 2 and the extension ring 201 are rotatably connected.

[0035] A first fitting pad 203 is disposed in the first tooth opening 202, wherein the first fitting pad 203 is connected to the extension ring 201. The first fitting pad 203 is made of rubber.

[0036] The connecting ring 22 is provided with a second tooth opening 2201, and a second fitting pad 2202 is placed in the second tooth opening 2201, and the second fitting pad 2202 is connected to the connecting ring 22. The second fitting pad 2202 is fixedly connected to the connecting ring 22.

[0037] After the wire is wound around the terminal post 13, the extending part of the wire passes through the second tooth socket 2201. When the protective cover 2 is connected to the connecting ring 22, the positions of the first tooth socket 202 and the second tooth socket 2201 are made to correspond. And when the wire contacts the first tooth socket 202, since the extension ring 201 is movably connected to the protective cover 2, the extension ring 201 will not rotate with the protective cover 2. As the distance between the protective cover 2 and the connecting ring 22 shortens, the first tooth socket 202 and the second tooth socket 2201 approach each other to squeeze the wire, so that a seal is formed at the position where the wire contacts the protective cover 2, thus preventing rainwater from entering the interior of the protective cover 2 when the terminal post 13 is powered, causing a short circuit of the wire.

[0038] The rest of the structure is the same as that of Embodiment 1.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
