Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides an energy storage device with a sealed structure. The energy storage device with a sealed structure includes an energy storage mechanism 1, a top cover 2 and a sealing structure 3. The sealing structure 3 squeezes the sealing strip 35 through the gap between the box body 11 and the top cover 2. The sealing strip 35 can be replaced without disassembling the top cover 2, which will not cause wear on the sealing performance, reduce operation time and save time and effort.

[0032] Specifically, the energy storage mechanism 1 includes a housing 11, a first guide groove 13 is provided on one side of the housing 11, a sealing strip 35 is slidably connected in the first guide groove 13, a guide ring 12 is fixedly connected to one side of the housing 11 and is located inside the sealing strip 35, a fixing plate 15 is fixedly connected to one side of the housing 11 and is located outside the sealing strip 35, and a battery 11-1 is installed inside the housing 11. By setting the guide ring 12, the top cover 2 can be better aligned with the bolt hole 18 and play a supporting role. The first guide groove 13 is set to guide and limit the insertion of the sealing strip 35. By setting the fixing plate 15, a gap is formed between the box body 11 and the top cover 2, allowing the second sealing block 32, the third sealing block 33 and the fourth sealing block 34 to move within it.

[0033] Specifically, the top cover 2 is installed on one side of the housing 11. A second guide groove 21 is provided on one side of the top cover 2, and a docking groove 22 is provided on one side of the top cover 2 and located inside the second guide groove 21. The second guide groove 21 is designed to cooperate with the first guide groove 13 and to serve as a limit when the sealing strip 35 is replaced.

[0034] Specifically, the sealing structure 3 is installed between the housing 11 and the top cover 2, including a first sealing block 31 that is slidably connected between the housing 11 and the top cover 2, a second sealing block 32, a third sealing block 33 and a fourth sealing block 34 that are slidably connected between the fixing plate 15 and the top cover 2 and are located between the fixing plate 15 and the sealing strip 35, a limiting mechanism 19 is installed on the housing 11 and cooperates with the first sealing block 31, the second sealing block 32, the third sealing block 33 and the fourth sealing block 34, and a sealing strip 35 is sleeved on the surface of the guide ring 12 and cooperates with the first guide groove 13 and the second guide groove 21.

[0035] By designing the sealing strip 35 to have a concave cross-section, and the first sealing block 31, the second sealing block 32, the third sealing block 33, and the fourth sealing block 34 to have isosceles trapezoidal cross-sections, the first sealing block 31, the second sealing block 32, the third sealing block 33, and the fourth sealing block 34 compress the sealing strip 35, and the two sides of the sealing strip 35 compress the housing 11 and the top cover 2 to form a sealing effect. By designing the first sealing block 31 to be removable, the sealing strip 35 can be replaced more easily.

[0036] Example 2 Reference Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, one side of the sealing strip 35 extends into the first guide groove 13, the other side of the sealing strip 35 extends into the first guide groove 13, and the surface of the sealing strip 35 contacts the inner wall of the first guide groove 13 and the second guide groove 21.

[0038] The first guide groove 13 and the second guide groove 21 are set to limit the movement when the sealing strip 35 is replaced.

[0039] The bottom of the housing 11 is fixedly connected to the base 14. The surfaces of the first sealing block 31, the second sealing block 32, the third sealing block 33, and the fourth sealing block 34 are all in contact with the surface of the sealing strip 35 and cooperate with each other.

[0040] By setting the base 14, the housing 11 can be prevented from directly contacting objects, which can better dissipate heat and also provide stability.

[0041] The housing 11 has multiple slots 16, and the limiting mechanism 19 is installed in the slot 16. A block 19-4 is slidably connected in the slot 16. A rod 19-3 is fixedly connected to one side of the block 19-4. The first sealing block 31, the second sealing block 32, the third sealing block 33 and the fourth sealing block 34 are all provided with a first positioning slot 19-7 and a second positioning slot 19-8. One end of the rod 19-3 is inserted into the first positioning slot 19-7 or the second positioning slot 19-8.

[0042] By designing the first positioning groove 19-7 and the second positioning groove 19-8, the insertion rod 19-3 is inserted into the second positioning groove 19-8 to limit the sealing strip 35 when the sealing block is pressing it. When the sealing strip 35 is replaced, the insertion rod 19-3 is inserted into the first positioning groove 19-7 to limit the sealing strip 35.

[0043] A spring 19-5 is fixedly connected between the surface of block 19-4 and the inner wall of groove 16, and a pull rod 19-2 is fixedly connected to the surface of plug rod 19-3, and it is slidably connected to box 11.

[0044] One end of the insertion rod 19-3 is provided with a bevel. When the handle 19-1 is pushed to compress the sealing block against the sealing strip 35, the insertion rod 19-3 will slide into the second positioning groove 19-8 to fix the sealing block.

[0045] Handles 19-1 are fixedly connected to the second sealing block 32, the third sealing block 33 and the fourth sealing block 34, and are slidably connected to the fixing plate 15.

[0046] When the spring 19-5 pulls the lever 19-2, the insert rod 19-3 pushes the block 19-4 to compress the spring 19-5. When the lever 19-2 is released, the spring 19-5 returns to its original position.

[0047] A groove 23 is provided between the housing 11 and the top cover 2 to cooperate with the first sealing block 31.

[0048] The first sealing block 31 is fixedly connected to a handle 19-1, which passes through the fixing plate 15 and is fixedly connected to one side of the second sealing block 32, the third sealing block 33 and the fourth sealing block 34. Pulling the handle 19-1 stops the sealing block from squeezing the sealing strip 35, and the sealing strip 35 can be replaced.

[0049] The first guide groove 13 and the second guide groove 21 are respectively connected to the groove opening 23.

[0050] The slot 23 is designed so that when replacing the sealing strip 35, it can be directly inserted into the first guide slot 13 and the second guide slot 21 that cooperate with the sealing strip 35.

[0051] Bolt holes 18 are provided on one side of the fixing plate 15, and bolts 17 are installed on one side of the top cover 2. One end of the bolt 17 is threaded to the bolt hole 18.

[0052] By setting the first guide groove 13 and the second guide groove 21 to have curved surfaces on both sides, it is easier to insert the sealing strip 35 more smoothly.

[0053] The housing 11 has a square hole 19-6 that mates with the pull rod 19-2, and it is connected to the groove 16.

[0054] The square hole 19-6 is designed to allow the pull rod 19-2 to slide within the square hole 19-6.

[0055] In use, the top cover 2 is fixed to one side of the box body 11 by bolts 17 and bolt holes 18. Pushing the corresponding handle 19-1 causes the first sealing block 31, the second sealing block 32, the third sealing block 33 and the fourth sealing block 34 to squeeze the U-shaped sealing strip 35, causing the sides of the U-shaped sealing strip 35 to deform and form a seal. The insertion rod 19-3 is inserted into the second positioning groove 19-8 to limit the position.

[0056] When replacing the sealing strip 35, pull the lever 19-2 to pull the insert rod 19-3 out of the second positioning groove 19-8, pull out the first sealing block 31 through the handle 19-1, pull the handles 19-1 on the second sealing block 32, the third sealing block 33 and the fourth sealing block 34 until they can no longer be moved, release the lever 19-2, the spring 19-5 returns to its original position and drives the insert rod 19-3 to be inserted into the first positioning groove 19-7 and fixed, then pull out the sealing strip 35 from the groove 23 and insert the new sealing strip 35.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
