In the first embodiment, please refer to fig. 1-4:

a novel clip-shaped seal ring comprises a clip-shaped seal ring 30 which is arranged between a battery upper shell 10 and a battery lower shell 20 and has a waterproof cross section in a clip shape; the top surface 31 and the bottom surface 32 of the outer side of the square-shaped sealing ring 30 are respectively provided with at least two convex arc water retaining strips 33 which are respectively abutted with the battery upper shell 10 and the battery lower shell 20; the center of the ring-shaped seal 30 is a hollow structure 36. The battery lower shell 20 is provided with a containing groove 21 for containing the clip-shaped sealing ring 30; the width between the two side surfaces of the square-shaped sealing ring 30 is the same as the width of the accommodating groove 21. The arc water bar 33 is abutted against the bottom surface of the accommodating groove 21; the left side surface 34 and the right side surface 34 of the outer side of the square sealing ring 30 are vertical planes; the top surface 31 and the bottom surface 32 of the square-shaped sealing ring 30 are respectively provided with two arc water bars 33, when the square-shaped sealing ring 30 is positioned in the accommodating groove 21, the side surfaces 34 are tightly attached to the two side walls of the accommodating groove 21, and after the battery upper shell 10 is buckled on the battery lower shell 20, four corners are fixed through screws 40, so that the bottom of the battery upper shell 10 extrudes the square-shaped sealing ring 30 to realize the waterproof of the joint; because the center of the square-shaped sealing ring 30 is a hollow structure, after the upper and lower shells are extruded, the space of the accommodating groove can be self-adapted to realize sealing, and the two arc water bars 33 arranged on the upper and lower sides are used for double-layer sealing and water proofing, when water enters, the water permeates from the joint of the upper and lower covers, viewed from the connecting structure positioned above, if the water wants to enter the battery, the water can enter the battery only after passing through the waterproof barrier formed by the double-layer arc water bars 33 on the top, and then the water can enter the battery through the tight contact between the extruded double-layer arc water bars 33 and the bottom of the upper shell 10 of the battery, so that the water can effectively enter the battery, viewed from the connecting structure positioned below, if the water wants to enter the battery, the water sequentially passes through the space on the left side of the side face 34 and the accommodating groove 21, the two layers of arc water bars, the space on the right side of the side face 34 and the accommodating groove 21, and the four layers of barriers in total, and the waterproof effect is further improved. The circular arc water bar 33 is connected with the side surface 34 through a chamfer surface 35. Compare the O shape sealing washer and the H shape sealing washer of traditional structure, the utility model discloses the sealing washer is behind adopting hollow structure, can be after the extrusion improvement holding power that lasts, and when the side 34 of returning the shape sealing washer 30 is close to two inside walls of storage tank 21, resilience force when can be with the extrusion is concentrated at top surface 31 and bottom surface 32, thereby strengthen the waterproof ability here, also strengthened weak department among the waterproof construction, and traditional O shape sealing washer and H shape sealing washer, generally, solid seal circle, its compression ratio itself is little, simultaneously be solid structure again, can't realize concentrating the effect of resilience force, even increase pressure bigger again, often the release department of pressure can not effectually concentrate at waterproof weak district, consequently still can have the risk of waterproof inefficacy, consequently, the roughness requirement on traditional sealing washer surface also can be higher, also can lead to the increase of cost.

In an embodiment of the present invention, the hollow structure 36 is a square with rounded corners.

In an embodiment of the present invention, the thickness of the solid ring of the square-shaped sealing ring 30 is 1-2mm; the height of the circular arc water bar 33 is 0.5-1mm.

In an embodiment of the present invention, the side length of the rounded square is 1.5-2.5 times of the thickness of the solid ring.

The utility model relates to a novel circle shape sealing washer, the shape is special, can bear the high pressure. The main used materials are ethylene propylene diene monomer, silicon rubber, nitrile rubber, chloroprene rubber, polytetrafluoroethylene, rubber and the like, and the materials can be selected according to different use occasions. Thus. The utility model discloses possess a lot of advantages:

1. the compression rate can reach 45% -60%, which is higher than the compression rate of 15% -30% of the common sealing ring.

2. The high pressure resistance can reach 100MPa to 120MPa, which is far higher than the ordinary sealing ring by 5MPa to 10MPa.

3. Higher volume-to-gap ratios allow for filling of larger volumes and gaps.

4. The processing cost is saved. The roughness requirement to the sealing washer is lower, and prior art common use requires for Ra =6.3-12.5 mu m, the utility model discloses the sealing washer is less than the roughness grade of ordinary sealing washer, and Ra =6.3-3.2 mu m.

5. The cost of the die is saved, and the cost of the product is reduced. The utility model discloses use the extrusion die rather than vulcanized membrane technology, can freely splice according to different projects and slot shape. And a pair of dies is not required to be arranged for production in each project, the material utilization rate is high, and the product cost can be effectively reduced.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
