[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0031] like Figure 1 Combination Figures 5-7 As shown, a lithium battery pack for a street light in one embodiment of the present invention includes a lithium battery pack shell 1, a lithium battery pack 101 installed inside the lithium battery pack shell 1, and a pair of male plug wires 9 respectively plugged into a pair of female plug wires 8. One male plug wire 9 is connected to the street light, and the other male plug wire 9 can be connected to the solar panel. The female plug wires 8 and the male plug wires 9 are matched.

[0032] An end cap 2 is installed on the lithium battery pack shell 1. A groove 103 is provided on the lithium battery pack shell 1, and a protrusion 201 is provided on the end cap 2. The groove 103 matches the protrusion 201, that is, the protrusion 201 can be inserted into the groove 103. At the same time, a sealing gasket 2011 is fixedly installed on the protrusion 201.

[0033] Preferably, in this embodiment, the sealing gasket 2011 is preferably a silicone rubber sealing gasket, which has good elasticity, corrosion resistance and sealing performance, and can provide a good sealing effect.

[0034] A locking assembly first bolt 6 is provided between the groove 103 and the convex frame 201. Multiple sets of first through holes 102 are provided on the lithium battery pack outer shell 1, and multiple sets of first screw holes 202 are provided on the convex frame 201. The first through holes 102 and the first screw holes 202 are matched, and the first bolt 6 is connected between the first through holes 102 and the first screw holes 202. Therefore, when the convex frame 201 is inserted into the groove 103, the first screw holes 202 on the convex frame 201 can be aligned with the first through holes 102 on the lithium battery pack outer shell 1. At this time, the first bolt 6 is inserted into the first through hole 102 and rotated into the first screw hole 202. The convex frame 201 can then be stably fixed inside the groove 103, meaning the end cap 2 can be securely installed on the lithium battery pack outer shell 1, ensuring the protection and sealing effect of the end cap 2 on the female connector 8 and the male connector 9.

[0035] like Figures 2-4As shown, a baffle 3 is fixedly installed on the end cap 2 by welding. The baffle 3 has multiple sets of strip-shaped slots 303. An insertion post 401 is fixedly installed on the insertion plate 4. The insertion post 401 can be inserted into the strip-shaped slots 303. The baffle 3 and the insertion plate 4 are interference-fitted. That is, the insertion plate 4 can be tightly inserted into the strip-shaped slots 303 on the baffle 3 through the insertion post 401.

[0036] The baffle 3 has multiple sets of second through holes 304, and the insert post 401 has a second screw hole 4011. The second through holes 304 and the second screw holes 4011 are matched, and a second bolt 7 is inserted between the second through holes 304 and the second screw holes 4011. Therefore, when the insert post 401 is fully inserted into the slot 303, the second through holes 304 on the baffle 3 are aligned with the second screw holes 4011 on the insert post 401. The second bolt 7 is then inserted into the second through holes 304 and rotated into the second screw holes 4011. At this point, the insert post 401 can be firmly inserted into the slot 303, meaning the insert plate 4 can be securely installed on the baffle 3.

[0037] The baffle 3 has a pair of circular holes 301, and the insert plate 4 has a pair of elliptical holes 402. The circular holes 301 are semicircular, and the elliptical holes 402 are semielliptical. The major axis of the elliptical holes 402 is equal to the diameter of the circular holes 301, and the minor axis is less than the radius of the circular holes 301. The ratio of the minor axis to the radius is 1 / 2.

[0038] A sealing lead-out structure is also provided between the baffle 3 and the insert plate 4. The male plug wire 9 passes through the sealing lead-out structure to the outside of the end cover 2. The sealing lead-out structure includes a compression ring 302.

[0039] The compression ring 302 is fixedly installed on the circular hole 301. The shape of the compression ring 302 matches the shape of the circular hole 301. The outer radius of the compression ring 302 is equal to the radius of the circular hole 301. At the same time, the inner radius of the compression ring 302 matches the outer radius of the male connector wire 9, ensuring that the male connector wire 9 can be inserted into the interior of the compression ring 302. A sealing ring is also installed inside the compression ring 302 to ensure the sealing effect of the wire harness.

[0040] Therefore, when the insert post 401 on the insert plate 4 is fully inserted into the slot 303 on the baffle 3, the second bolt 7 is inserted into the second through hole 304, and then the second bolt 7 is rotated and connected into the second screw hole 4011. At this time, the insert plate 4 is tightly fixed on the baffle 3.

[0041] Furthermore, the elliptical hole 402 on the insert plate 4 can be close to the circular hole 301 on the baffle plate 3. The elliptical hole 402 can squeeze the compression ring 302 fixedly installed inside the circular hole 301. At this time, the male plug wire 9 inside the compression ring 302 will also be squeezed and fixed, so the male plug wire 9 will not move arbitrarily, ensuring the stability of the plug. At the same time, the compression ring 302 squeezes and hugs the male plug wire 9, which will also improve the sealing effect and effectively prevent rainwater from entering its interior.

[0042] The engagement of the plug 401 on the plug plate 4 and the strip slot 303 on the baffle 3 can effectively stabilize the male plug cable 9, and at the same time, it can also make it easy to open the end cover 2, so that the wire harness inside the end cover 2 can be organized and arranged when it is not necessary to remove the end cover 2. It is very convenient and achieves two goals at once.

[0043] Both the baffle 3 and the insert plate 4 are equipped with handles 5. When it is necessary to insert the insert plate 4 into the baffle 3 separately, you can hold the handle 5 on the insert plate 4 to install the insert plate 4 into the baffle 3. At the same time, when the lithium battery pack is completely installed, that is, when the end cover 2, the baffle 3 and the insert plate 4 are all fixedly installed on the lithium battery pack shell 1, you can also easily move the entire lithium battery pack by taking the handles 5 on the baffle 3 and the insert plate 4 at the same time.

[0044] In use, first remove the two sets of female plug wires 8 inside the lithium battery pack casing 1, then connect the two sets of male plug wires 9 to the two sets of female plug wires 8. Next, remove the end cap 2 and pass the wire harness of the male plug wires 9 through the compression ring 302 installed on the baffle 3. At this time, take the insert plate 4 and hold the handle 5. Align the insert post 401 on the insert plate 4 with the strip slot 303 on the baffle 3 and insert it. When the insert post 401 is fully inserted into the strip slot 303, the second screw hole 4011 will be aligned with the second through hole 304. Then, connect the second bolt 7 between the second through hole 304 and the second screw hole 4011, and the insert plate 4 will be stably fixed on the baffle 3.

[0045] At this time, the elliptical hole 402 will come into contact with the compression ring 302 and compress the male plug wire 9 inside the compression ring 302. The male plug wire 9 will then be fixed inside the compression ring 302, and the male plug wire 9 will achieve a good sealing effect, which can effectively prevent rainwater from entering.

[0046] Next, remove end cap 2 and insert it into the groove 103 on the lithium battery pack outer shell 1, aligning the protrusion 201 on end cap 2 with the groove 103 on the lithium battery pack outer shell 1. At this time, the four sets of first screw holes 202 on end cap 2 will be aligned with the four sets of first through holes 102 on the lithium battery pack outer shell 1. Take the first bolt 6 and connect the first bolt 6 one by one between the first through holes 102 and the first screw holes 202. End cap 2 will then be stably fixed on the lithium battery pack outer shell 1. At this time, the female plug wire 8 and male plug wire 9 will be well protected inside end cap 2, and will not be affected by the external environment. Their anti-aging ability is enhanced, which can improve the service life of female plug wire 8 and male plug wire 9 and reduce maintenance costs.

[0047] When it is necessary to inspect the female plug wire 8 and male plug wire 9 inside the end cover 2, the second bolt 7 can be removed, and then the handle 5 can be held to pull the plug plate 4 out of the baffle 3. The female plug wire 8 and male plug wire 9 can be inspected and sorted. After the inspection is completed, the plug plate 4 can be reinstalled back into the baffle 3.

[0048] Compared with the prior art, the lithium battery pack for streetlights of this utility model can protect the male and female connectors from damage by the external environment through the protective function of the end caps, and can also increase their anti-aging ability, extend the service life of the male and female connectors, and eliminate safety hazards during the use of the male and female connectors.

[0049] 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.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
